The directional switch section 20'has a directional switch housing 21 (21a, 21b), a directional switch knob 22 (22a, 22b), a directional switch printed circuit board 24, and a plurality of directional switches 25a, 25b. , Equipped with. The directional switch housing 21 (21a, 21b) comprises a directional switch lower housing 21b and a directional switch upper housing 21a that are attached to the steering wheel, but the directional switch lower housing 21b and the directional switch upper housing 21a. Are combined to form an internal space. A directional switch printed circuit board 24 is arranged in this internal space. The directional switch printed circuit board 24 has various configurations such as a structure that electrically communicates with the control unit 60 via a connector or the like, or the control unit of the vehicle via an external electric device such as SRC. It can be adopted.
An opening is provided in the directional switch upper housing 21a, through which the directional switch knobs 22 (22a, 22b) are movably arranged with respect to the directional switch housing 21. The directional switch knob 22 includes a directional switch enter knob 22a and a directional switch round knob 22b, and the directional switch enter knob 22a is arranged at the center of the directional switch round knob 22b as separate components from each other. However, such a configuration is merely an example of this embodiment, and the present invention is not limited thereto. An extension is formed on the outer circumference of the directional switch enter knob 22a, and a knob stopper 22d is provided on the directional switch round knob 22b, but the knob stopper 22d and the extension of the directional switch enter knob 22a can contact each other. By adopting the structure, it is possible to prevent the directional switch enter knob 22a from being accidentally detached to the outside. The directional switch round knob mounting portion 26a is provided at the lower end of the directional switch round knob 22b, and the directional switch lower housing 21b is provided with the round knob mounting compatible portion 26b. The 26a has a structure that allows partial contact with the round knob mounting compatible portion 26b, and can prevent the directional switch round knob 22b from being accidentally detached to the outside.
The directional switches 25a and 25b are arranged on one surface of the directional printed circuit board 24, and the directional switches 25a and 25b are realized by the push type tact switch in this embodiment. The directional switches 25a and 25b include a directional enter switch 25a and a directional round switch 25b. The directional switch knob 22 is provided with a directional enter switch movable portion 23a and a directional round switch movable portion 23b, respectively, so as to correspond to the directional switches 25a and 25b.
As described above, the directional switches 25a and 25b generate various union signals that can perform a predetermined control mode selected by the driver by electrically communicating with the control unit 60 and / or an external electric device. Can be transmitted.
The embodiments are merely examples for explaining the present invention, and the present invention is not limited thereto. For example, the haptic rotary switch sensing unit and the haptic enter switch of the haptic steering wheel switch system according to the present invention may be realized by a non-contact switch having a non-contact sensing sensor or the like. Further, in the above embodiment, it is disclosed that a control unit for controlling the haptic rotary switch unit of the haptic steering wheel switch unit is externally attached, but in some cases, the haptic steering wheel switch unit is a built-in dedicated control. It may have a structure further including a part, and the transmission weight may be arranged not only on the haptic transmission knob but also on other components constituting the rotational movement, and includes a haptic rotary switch part attached to the steering wheel. Various modifications are possible within the scope of providing the haptic steering wheel switch unit and the haptic steering wheel switch system.
The haptic steering wheel switch unit and the haptic steering wheel switch system provided with the haptic steering wheel switch unit according to the present invention give the driver tactile cognition by a haptic feeling and prevent the attention from being dispersed during driving to ensure safe driving of the driver. It can be realized by vehicle switches and safety devices, and may be arranged not only on the steering wheel of the vehicle but also on the center face or dashboard, and in some cases, the switch operation like the game machine operation panel. It can be applied in various fields in technical fields that require sensory cognition.
