Multi-directional button for handheld electronic device

Multi-directional key device for handheld electronic products

The present invention relates to a control device, and more particularly to a multi-directional key device for a handheld electronic product.

In view of the fact that a single-directional button of a general portable electronic device (or a handheld electronic device, such as a personal digital assistant PDA or a palm-type game machine) has a large setting space and is inconvenient to operate, the creator has created As shown in FIG. 1 and FIG. 2, the water-repellent control device 20 is mounted on an electronic device 10 having an upper cover 11 to which a lock is fixed. The circuit board 12 in the upper cover 11 and a micro-patch switch 13 and a digital button switch 14 respectively fixed to the circuit board 12 and electrically connected to each other are mounted.

The waterproof control device 20 has a resilient button body 21 and a guide button 22. The elastic button body 21 is made of rubber and is sandwiched between the upper cover 11 and the circuit board 12. The elastic button body 21 has a corresponding shape formed by the micro switch 13 and the push button switch 14 The multi-directional button 211 and the number button 212. The guide button 22 is mounted and fixed in the multi-directional button 211 while the micro-rod switch 13 is sleeved.

In use, the user only needs to operate the multi-directional button 211 by a single finger, and the micro-rod switch 13 can be driven through the guide button 22, thereby achieving the effect of saving installation space and convenient operation, and the elastic button can be used. The body 21 produces a waterproof and dustproof effect, and further protects components mounted between the upper cover 11 and the circuit board 12.

Although the patent has the above-mentioned use effect, there is still a user pressing the multi-directional button 211, because the multi-directional button 211 is made of rubber, and has a large buffering resistance, thereby affecting the micro-rod switch 13 The movement feedback power transmission speed, and thus there is a problem that the finger touch time difference is long and the finger touch sensitivity is poor.

Accordingly, it is an object of the present invention to provide a multi-directional key device for a hand-held electronic product that can reduce the time difference between the finger touch and the sensitivity of the finger touch.

Therefore, the multi-directional key device of the present invention is mounted on a handheld electronic product, the handheld electronic product has an upper cover provided with a receiving hole, a circuit board fixedly fixed in the upper cover, and is fixedly mounted on the circuit A micro-switch that electrically connects the boards to each other. The multi-directional key device comprises a rubber pad and a plastic sleeve.

The rubber pad is sandwiched and fixed between the upper cover and the circuit board, and includes a top surface and a bottom surface opposite to each other, and a receiving hole formed on the top cover from the top surface toward the top end respectively a convex ring inside, and a multi-directional key located in the convex ring and provided with a perforation.

The plastic sleeve is mounted and fixed in the multi-directional key, has a top wall located in the perforation, and a surrounding wall extending from the top wall toward the bottom end, the top wall and the surrounding wall are cooperatively defined To sleeve the sleeve hole of the micro-rod switch.

With the above composition, when the user directly operates the plastic sleeve, the micro-rod switch can be driven, and the moving feedback force of the micro-rod switch can be directly transmitted to the plastic sleeve and the user's finger, so that the novel has It can reduce the time difference of finger touch and improve the use characteristics of finger touch sensitivity.

The foregoing and other technical aspects, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Before the present invention is described in detail, it is to be noted that the relative positional terms used in the following description, such as "top" and "bottom", are used in the normal direction of use.

As shown in FIGS. 3, 4, and 5, the preferred embodiment of the multi-directional key device of the present invention is mounted on a handheld electronic product 30, which can be a personal digital assistant (PDA) or a palm-type game machine. And so on, having an upper cover 31 provided with a receiving hole 311, a circuit board 33 fixed in the upper cover 31 by a plurality of screws 32, and a micro-mounting and fixing to the circuit board 33 and electrically connected to each other A micro-switch switch 34 (micro Stick Switch), the micro-rod switch 34 can be a multi-directional switch with front, rear, left, and right control directions, or can have front, rear, left, and right control directions. And the multi-directional switch that uses the function of the down button.

The preferred embodiment includes a rubber pad 40 and a plastic sleeve 50.

The rubber mat 40 can be waterproof and dustproof by its own characteristics, including a top surface 41 and a bottom surface 42 which are opposite to each other, and a receiving hole 311 for inserting into the upper cover 31 from the top surface 41 toward the top end. The inner convex ring 43, a multi-directional key 44 formed from the top surface 41 toward the top end and located in the convex ring 43, and a through hole 45 provided in a top wall 441 of the multi-directional key 44.

The multi-directional key 44 has a surrounding wall 442 extending from the top surface 41 toward the top end, and a top wall 441 connecting the surrounding wall 442. The top wall 441 and the surrounding wall 442 cooperate to define a top and bottom opening. Room 443.

Further, the rubber mat 40 has a hardness of 30 to 90 in the present invention.

The plastic sleeve 50 is mounted and fixed in the open chamber 443 of the rubber mat 40, and includes a top wall 51 located in the through hole 45, and a surrounding wall 52 extending from the top wall 51 toward the bottom end, the top wall The 51 and the surrounding wall 52 cooperate to form a sleeve hole 53 for receiving the micro-rod switch 34.

Further, the top wall 51 of the plastic sleeve 50 has a small diameter portion 511 for inserting the through hole 45 of the rubber pad 40, and a large diameter portion 512 located in the open chamber 443. The small diameter portion 511 A shoulder portion 513 is naturally formed between the large diameter portion 512 to increase the contact area with the top wall 441, and the bonding strength between the rubber pad 40 and the plastic sleeve 50 can be relatively increased.

It should be noted that, during the production, the plastic sleeve 50 and the rubber pad 40 can be integrally molded by using an insert molding method or a double injection molding method, thereby making the plastic sleeve 50 and the plastic sleeve 50 Both rubber pads 40 have excellent bonding strength.

In use, the user only needs to place the finger on the top wall 51 of the plastic sleeve 50, and the plastic sleeve 50 can be operated to move the micro-switch 34 in a predetermined direction, because the feedback force of the micro-switch 34 is directly The rubber sleeve 50 and the user's finger are transmitted, so that the utility model has the advantages and advantages of reducing the touch time difference of the finger and improving the sensitivity of the touch. In addition, the rubber pad 40 can be waterproof and dustproof. Further, the effects and advantages of protecting the components mounted between the upper cover 31 and the circuit board 32 are obtained.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification according to the scope of the novel application and the new description of the present invention. , are still within the scope of this new patent.
