(Switch device) As shown in FIGS. 1 to 3, the switch device 1 includes a pressing operation unit 2, a shaft unit 3, a switch unit 4, and a circuit board 40 shared with the instrument device 100. Further, the pressing operation unit 2 includes a pressing unit 2c and a support unit 2e. As shown in FIG. 1, the switch device 1 according to the present embodiment is composed of one pressing operation unit 2, a shaft unit 3 corresponding to the pressing operation unit 2, a switch unit 4, and the like, and is arranged at two locations on the left and right of the instrument device 100. Has been done. The two switch devices 1 and 1 on the left and right are for switching the display mode (such as resetting the odometer / trip meter) of the display display 30 and changing the emission brightness of the illumination of the instrument device 100, for example. Since these switch devices 1 and 1 have the same structure, the switch device 1 on the right side will be described below.

The pressing operation unit 2 is a portion that is pressed by a user (mainly a driver of a vehicle on which the instrument device 100 is mounted). The pressing operation unit 2 is made of a predetermined elastic material such as ethylene propylene rubber. The pressing operation unit 2 has a columnar pressing unit 2c, and the pressing operation unit 2 is formed in an oblique direction in which the pressing operation unit 2 is tilted in a predetermined direction with respect to the axial direction of the pressing unit 2c. The tilted diagonal direction of the pressing operation unit 2 is the shaft portion in which the axial direction of the pressing unit 2c operates the switch unit 4 with the pressing operation unit 2 attached to the through hole 92 of the transparent plate 91 of the inclined outer case 90. The direction coincides with the axial direction of 3. The pressing operation unit 2 further has a support portion 2e that surrounds the pressing portion 2c and elastically supports the pressing portion 2c so as to be displaceable. The support portion 2e is formed integrally with the pressing operation portion 2 and is inclined with respect to the surface direction of the circuit board 40. The switch portion 4 is mounted on the circuit board 40, and the direction perpendicular to the axial direction of the shaft portion 3 of the switch portion 4 is the surface direction of the circuit board 40. The shaft portion 3 extends from the switch portion 4 toward the pressing portion 2c and comes into surface contact with the tip surface 2d of the pressing portion 2c. The shaft unit 3 is pushed by the pressing unit 2c that is displaced by the pressing operation on the pressing operation unit 2 and moves to the circuit board 40 side to operate the switch unit 4. As a result, the pressing unit 2c is displaced in the axial direction by the pressing operation of the pressing operation unit 2 attached in the inclined oblique direction, and the shaft unit 3 is pushed by the pressing unit 2c to move to the circuit board 40 side and switch. Operate part 4. That is, as shown in FIG. 3, a pressing portion 2c protruding in a columnar shape is integrally provided on the back side of the pressing operation portion 2. The back side surface (tip surface) 2d of the pressing portion 2c is a pressing surface, and is in surface contact with the operation surface 3a on the front side of the shaft portion 3. By pressing the pressing operation unit 2, the switch unit 4 is operated via the shaft unit 3. Details of each part of the pressing operation part 2 will be described after the description of the shaft part 3 and the switch part 4.

The shaft portion 3 is located on the back side of the pressing operation portion 2, and the operation rod 4a of the switch portion 4 is integrally formed. The shaft portion 3 is a member extending perpendicularly to the surface direction of the substrate 41 from the switch portion 4 mounted on the substrate 41 of the circuit board 40 toward the pressing operation portion 2. The shaft portion 3 has, for example, a cylindrical shape, and is formed separately from the pressing operation portion 2. When the pressing operation unit 2 is pressed, the shaft unit 3 moves to the circuit board 40 side (sinking direction) together with the pressing operation unit 2. That is, as shown in FIG. 2, the shaft portion 3 includes a tubular guide portion 72 formed through the facing portion 70, a through hole 62 formed in the dial 60, and a shaft arrangement portion of the inner case 50. It is inserted through the through hole 52 formed in 51 and can be moved in the front and back directions of the instrument device 100. The circular operation surface 3a on the front side of the shaft portion 3 faces parallel to the back surface (tip surface) 2d of the pressing portion 2c of the pressing operation portion 2, and is arranged so as to make surface contact by the pressing operation of the pressing operation portion 2.

The portion of the shaft portion 3 located inside the middle case 50 constitutes the operation rod 4a of the switch portion 4. A disk-shaped spring receiver 3b is formed on the shaft portion 3 constituting the operation rod 4a, and a locking portion 3c is formed on a portion protruding through the through hole 52 of the inner case 50. A coil spring 3d is interposed between the spring receiver 3b and the shaft arrangement portion 51 of the inner case 50 in the shaft portion 3. The shaft portion 3 (operation rod 4a) is always urged to the front side, and the urging position to the front side is regulated by locking the locking portion 3c to the inner case 50. As a result, the shaft portion 3 (operation rod 4a) is arranged in the direction perpendicular to the surface direction of the substrate 41 (the approximate normal direction of the substrate 41 (including the normal direction)) and has a restoring force due to the coil spring 3d. ing. The shaft portion (operation rod 4a) 3 has a light-shielding portion 3e on the back side of the through hole 62 of the dial 60 to block the back side of the through hole 62 to prevent the illumination light of the instrument device 100 from leaking. There is.

The switch unit 4 includes a contact switch 4b mounted on the front side of the substrate 41. In the switch unit 4, the contact switch 4b is pressed by the operation rod 4a (shaft unit 3). The operation rod 4a (shaft portion 3) is integrally provided with a switch operation portion 4c facing the contact switch 4b. The contact switch 4b is pressed by the switch operating unit 4c. The operating rod 4a (shaft portion 3) and the switch operating portion 4c have a restoring force in the direction perpendicular to the surface direction of the substrate 41, that is, in the axial direction of the operating rod 4a. That is, the switch unit 4 is configured to return to the state before being pressed by its own restoring force after being pressed. The switch unit 4 is electrically connected to the above-mentioned control unit (not shown) by a printed wiring or the like formed on the substrate 41 of the circuit board 40. When pressed, the switch unit 4 turns on or off, and outputs an operation signal indicating the on or off state to the control unit. The control unit changes the display mode of the display display 30 or changes the emission brightness of the light source (not shown) according to the operation signal output in this way.

In the switch device 1, the switch unit 4 is configured to be turned on / off when the pressing operation unit 2 provided on the upper case 90 is pressed. As a result, the user presses the switch unit 4 from the pressing operation unit 2 via the shaft unit 3 (operation rod 4a), so that the switch operating unit 4c presses the contact switch 4b, and the display mode of the display display 30 is displayed. Various operations such as change are possible.

The pressing operation unit 2 is a member for pressing the switch unit 4 via the shaft unit 3 (operation rod 4a), and is attached to the through hole 92 of the inclined transparent plate 91 of the upper case 90. The pressing operation unit 2 is for preventing water from entering through the through hole 92 of the transparent plate 91 and improving the operation feeling of the pressing operation for reliable operation. The pressing operation unit 2 is located around the shaft portion 3 so as to protrude from the seal portion 2a for sealing the through hole 92 formed in the upper case 90 toward the substrate 41 of the circuit board 40 and move the shaft 3. It has a guide portion 2b for guiding the guide portion 2b and a pressing portion 2c formed in the guide portion 2b and projecting into a columnar shape in surface contact with the shaft portion 3. As described above, the pressing operation unit 2 is made of a predetermined elastic material such as ethylene propylene rubber. As shown in FIG. 1, the pressing operation unit 2 has a planar shape formed into a substantially quadrangular shape with four corners arcuate, and is attached so as to cover the through hole 92 of the transparent plate 91. The inclined surface of the transparent plate 91 to which the pressing operation unit 2 is attached includes either a flat surface or a curved surface.

The seal portion 2a is formed in a tubular shape on the back side of the pressing operation portion 2, and an annular groove is formed on the outer periphery of the tubular shape. The annular groove of the seal portion 2a has, for example, a saddle shape, and covers the vertical inner peripheral surface and the inclined surfaces of the front and back surfaces of the through hole 92 of the transparent plate 91 to be in a watertight state. The guide portion 2b protrudes vertically from the tubular portion covering the inner peripheral portion of the through hole 92 of the seal portion 2a to the back side, and is integrally formed in a cylindrical shape. As shown in FIG. 3, the pressing portion 2c is integrally provided in the guide portion 2b so as to project in a columnar shape in a vertical direction inclined with respect to the pressing operation portion 2. As a result, the back side surface (tip surface) 2d of the pressing portion 2c becomes parallel to the operation surface 3a on the front side of the shaft portion 3 in the direction perpendicular to the surface direction of the substrate 41, and is in surface contact with each other. On the front side of the pressing operation portion 2, a supporting portion 2e that surrounds the pressing portion 2c and elastically supports the pressing portion 2c so as to be displaceable is further formed. The support portion 2e is formed in a dome shape on the pressing operation portion 2 in accordance with the position of the pressing portion 2c. The user elastically deforms the support portion 2e and displaces the pressing portion 2c to perform the pressing operation in order to operate the switch device 1.

In the pressing operation unit 2, the supporting portion 2e is a portion (region) 2g where the side L1 having a large distance L from the inclined surface of the upper case 90 to the back surface (tip surface) of the pressing portion 2c is easily bent, and the distance L The small side L2 is set as the part (region) 2h that is difficult to bend. That is, the support portion 2e is inclined with respect to the surface direction of the circuit board 40, and the region 2g of the side L1 having a long distance L to the tip surface 2d of the pressing portion 2c is the region 2h of the side L2 having a short distance L. It is formed to be more flexible than. In the present embodiment, as shown in FIG. 3, the cylindrical side surface of the pressing portion 2c is scraped off on the support portion 2e to form the flat surface portion 2f over the entire length in the front-back direction, so that the portion (region) that is easily bent is 2 g and is bent. A difficult part (area) 2h is formed. As a result, on the back surface of the pressing operation unit 2, the flat surface portion 2f side becomes a wide and easily flexible portion (area) 2g with the guide portion 2b, and the opposite side of the flat surface portion 2f has a narrow space with the guide portion 2b and is difficult to bend. Part (area) is 2h. Therefore, when the dome-shaped support portion 2e is pushed in, the side L2 (the portion (region) 2h that is difficult to bend) with a small distance L from the inclined surface of the upper case 90 to the back surface (tip surface) of the pressing portion 2c is used as the base point. The amount of deflection of the side L1 (flexible part (area) 2 g) with a large distance L increases. Therefore, the flexible portion 2g of the support portion 2e is extended and can be bent so as to rotate clockwise in FIG. 3 (b) (see FIG. 4 (a)). According to such a pressing operation unit 2, even if the user pushes the support portion 2e of the pressing operation unit 2 perpendicularly to the inclined surface of the upper case 90, the distance L from the inclined surface to the back surface side of the pressing portion 2c is L. By setting the large side L1 to a flexible portion (region) of 2 g, the direction of the pressing force applied to the pressing operation portion 2 can be directed toward the axial direction (standing direction) of the shaft portion 3, and the shaft portion 3 can be set. The shaft portion 3 can be pushed in by bringing the back surface (tip surface) 2d of the pressing portion 2c into surface contact with the operation surface 3a of the shaft portion 3 without tilting.

The switch device 1 configured in this way operates as follows. When the pressing operation unit 2 is pressed (pushed in), the shaft unit 3 is moved toward the substrate 41 side of the instrument device 100 as the pressing operation unit 2 is pushed in. In this pressing operation of the pressing operation unit 2, as described above, the support portion 2e is pushed vertically into the transparent plate 91 of the upper case 90, but the pressing portion 2c is in surface contact with the operation surface 3a of the shaft portion 3. Since the back side surface (tip surface) 2d of the shaft portion 2 has a flexible portion 2g formed on the support portion 2e of the pressing operation portion 2, the shaft portion 3 is pushed along the upright direction (axial direction). As a result, the operation rod 4a integrated with the shaft portion 3 and the switch operation portion 4c are moved. When the switch operating unit 4c is moved, the switch operating unit 4c pushes the contact switch 4b toward the board 41. As a result, the switch unit 4 is turned on or off. The pressed switch unit 4 outputs an operation signal indicating on or off to the control unit, and the control unit controls a predetermined operation (for example, switching the display image of the display display 30).

When the user stops the pressing operation (for example, when the finger is released from the pressing operation unit 2), the operating rod 4a integrated with the shaft unit 3 and the switch operating unit are due to the restoring force of the switch unit 4 in the approximate normal direction of the substrate 41. 4c is returned. As a result, when the pressing operation is stopped, the switch device 1 returns to the initial state again.

When the switch device 1 is configured as described above, the user can execute various settings of the instrument device 100 by the pressing operation from the pressing operation unit 2.

According to this switch device 1, even if the pressing operation unit 2 attached to the curved inclined surface is operated, the pressing operation unit 2 is pushed in the axial direction of the shaft unit 3, and the operation feeling (operation feeling) is excellent. The on / off of the switch unit 3 can be reliably operated. That is, when the pressing operation portion 2 attached to the through hole 92 of the transparent plate 91 of the inclined upper case 90 is pushed in, the pressing force tends to be applied vertically to the inclined transparent plate 91, and the pressing portion 2c is tilted to the shaft. It was difficult to transmit in the pressing operation direction of the part 3 (the direction perpendicular to the surface direction of the substrate 41) (see FIG. 4B), but in this switch device 1, the flexible part 2g of the pressing operation part 2 The hard-to-bend portion 2h can be bent so as to extend from the base point, and the pressing portion 2c can be pushed in the direction perpendicular to the surface direction of the substrate 41 of the circuit board 40, which is the axial direction of the shaft portion 3.

Further, since the shaft portion 3 is located in the guide portion 2b of the pressing operation portion 2, the movement is guided by the guide portion 2b, and the shaft portion 3 is surely pushed or returned in the axial direction (standing direction). Can be done. Further, according to the switch device 1, a seal portion 2a is formed in the pressing operation portion 2 and seals the inner peripheral portion and the front and back surfaces of the through hole 92 of the upper case 90 so as to cover the through hole. It can be waterproofed by sealing the ingress of rainwater from 92. As a result, the switch device 1 can be installed by preventing rainwater or the like from entering the instrument device 100 of a two-wheeled vehicle or an open car. Further, the pressing operation portion 2 is formed with a rib on the guide portion 2b that protrudes toward the shaft portion 3 and narrows the gap with the shaft portion 3. As a result, by projecting from the inner peripheral side of the guide portion 2b toward the shaft portion 3 side to form a rib (not shown), the gap with the shaft portion 3 can be narrowed and the eccentricity of the shaft portion 3 can be suppressed. You can guide more reliably. Instead of forming ribs on the guide portion 2b, a protruding portion (not shown) protruding toward the outer periphery may be formed on the shaft portion 3 to narrow the gap with the guide portion 2b. By doing so, the eccentricity of the shaft portion 3 can be suppressed, and the movement of the shaft portion 3 in the front-back direction can be guided more reliably. In the above embodiment, the support portion 2e of the pressing operation portion 2 is provided by forming a flat portion 2f on the cylinder of the pressing portion 2c so that the portion 2g that easily bends and the portion 2h that does not easily bend according to the inclined surface are provided. However, without changing the shape of the pressing portion 2c, the wall thickness of the supporting portion 2e of the pressing operation portion 2 may be changed to be a flexible portion 2g or a non-flexible portion 2h. Further, the formation of the flat surface portion 2f of the pressing portion 2c may be combined with changing the wall thickness. Further, the shape of the pressing portion 2c is not limited to the case where the flat portion is formed as a columnar shape, and the shape of the pressing portion 2c may be formed as a prismatic shape with a notched side surface for easy bending.

In the above embodiment, the case where the operation rod 4a of the switch portion 4 is integrally provided with the shaft portion 3 has been described as an example, but the present invention is not limited to this. The shaft portion 3 and the operation rod 4a of the switch portion 4 may be connected as separate bodies.

Further, the case where the pressing operation unit 2 is provided with the seal unit 2a and the guide unit 2b has been described as an example, but if it is not a two-wheeled vehicle or an open car, the seal unit 2a can be omitted and the guide unit 2b Is not always necessary, and if the shaft portion 3 is provided according to the length or the like, the movement of the shaft portion 3 can be stabilized.

The switch device 1 described above has a columnar pressing portion 2c, and is pressed in an oblique direction tilted in a predetermined direction in the axial direction of the pressing portion 2c to displace the pressing portion 2c. The circuit board 40 on which the part 2 and the switch part 4 are mounted and whose surface direction is perpendicular to the axial direction, and the tip surface (back side surface) of the pressing part 2c extending from the switch part 4 toward the pressing part 2c. A shaft portion 3 that comes into surface contact with 2d and is displaced by a pressing operation on the pressing operation portion 2 and is pushed by the pressing portion 2c to move to the circuit board 40 side to operate the switch portion 4 is provided. Further has a support portion 2e that surrounds the pressing portion 2c and elastically supports the pressing portion 2c so as to be displaceable. The support portion 2e is inclined with respect to the surface direction of the circuit board 40, and the pressing portion 2c The region 2g of the side L1 having a long distance L to the tip surface 2d is formed to be more flexible than the region 2h of the side L2 having a short distance L. In this way, the pressing operation unit 2 is expanded by extending 2 g of the easily flexible region (side) to increase the amount of deflection, and the opposite side of the less flexible region (side) 2h is pushed into the base point to push the inclined surface of the upper case 90. The shaft portion 3 can be pushed in the axial direction even if it is pushed against the shaft (see FIG. 4 (a)), the operation feeling is excellent, and the switch device 1 can be reliably operated via the shaft portion 3. ..

Further, the pressing operation unit 2 has a seal portion 2a for sealing the through hole 92 formed in the upper case 90 to which the support portion 2e is attached, and the seal portion 2a seals the through hole 92 of the upper case 90. Can be made watertight. As a result, even in a two-wheeled vehicle or an open car, it is possible to install the switch device 1 which prevents rainwater from entering and has an excellent operability.

Further, the pressing operation unit 2 has a guide portion 2b that protrudes from the support portion 2e toward the circuit board 40 side and is located around the shaft portion 3 to guide the movement of the shaft portion 3. You can surely guide the movement of 3. As a result, the switch device 1 having an excellent operability can be obtained.

Further, in the pressing operation unit 2, the support portion 2e is configured to easily bend by forming a flat surface portion 2f on the outer cylindrical outer portion of the pressing portion 2c, so that the easily flexible portion 2g and the less flexible portion 2h can be separated. It can be formed, and the shaft portion 3 can be reliably pushed in the axial direction by the pressing operation portion 2.

Further, in the pressing operation unit 2, the guide portion 2b is formed with a rib protruding toward the shaft portion 3 to narrow the gap, and the shaft portion 3 is formed with a protruding portion protruding toward the guide portion 2b to narrow the gap. By doing so, the movement of the shaft portion 3 can be guided more reliably, the operation feeling is improved, and the switch device 1 can be operated reliably.
