Description

Buttons and Electronics

technical field

The utility model relates to a button, and in particular to an electronic device with a button.

Background technique

The existing key is formed by assembling a key body on a key base. When the user presses the key body, the key body will move and touch the trigger part in the key base, thereby forming an electrode conduction and transmitting an electronic signal to a central processing unit. However, when the keys are assembled on the key base, they are usually heat-welded for positioning. However, this is likely to cause a gap between the key and the key base when the key is pressed due to assembly tolerances. Once the electronic device has liquid or dust on the surface of the key, it is easy to enter the key base through this gap, causing the electronic device Electronic components and circuit boards inside are damaged by a short circuit. Therefore, how to improve the above-mentioned shortcomings so that the keys have waterproof and dustproof functions is a problem that manufacturers are eager to solve.

Detailed ways

FIG. 1 is an exploded view of an electronic device at a key according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the key of FIG. 1 installed on the key base. Please refer to FIG. 1 and FIG. 2 at the same time. The electronic device 100 includes a key 200 and a key base 300 , wherein the key 200 is disposed on the key base 300 . The key base 300 includes a first step portion 310 and a first stop portion 320 . The button 200 includes a button body 210 , a sealing member 220 and an elastic member 230 . The key body 210 includes a pressing portion 212 , a protrusion 214 and at least one hook 216 . The pressing part 212 is disposed on the step part 310 . The protrusion 214 extends from the pressing portion 212 toward the key base 300 . The hook 216 is engaged with the first stop portion 320 . In this embodiment, the sealing member 220 is, for example, a rubber washer, which is compressed between the pressing portion 212 and the step portion 310 by the key body 210 . The elastic member 230 is, for example, a telescopic spring, which is sleeved on the boss 214 .

FIG. 3 is a schematic diagram of the post pressing contact portion of FIG. 2 . Please refer to FIG. 2 and FIG. 3 at the same time. When the user presses the pressing portion 212 , the protrusion 214 moves from the first position A to the second position B, and the pressing portion 212 compresses the elastic member 230 at this moment. When the user no longer presses the pressing portion 212 , the elastic force of the elastic member 230 will drive the boss 214 to move from the second position B back to the first position A. As shown in FIG.

In the electronic device 100 and its button 200 of the present invention, since the sealing member 220 is disposed between the button body 210 and the step portion 310 , when the button 200 is mounted on the button by snapping the hook 216 to the first stopper portion 320 When the seat 300 is used, the sealing member 220 will be pressed by the key body 210 in the gap between the pressing part 212 and the step part 310, so the key 200 improves the problem that the key 200 is positioned on the key base 300 by thermal welding in the prior art. The gap between the keys 200 prevents foreign matter such as water or dust from entering the key base 300 through the gap between the key 200 and the key base 300 .

Moreover, the button 200 also includes an elastic member 230 sheathed on the protrusion 214 , so after the user presses the button 200 , the elastic member 230 restores the button 200 to its original unpressed state through its elastic restoring force. Based on the above, the button 200 and the electronic device 100 of the present invention have considerable practicability.

Further description is as follows, please refer to FIG. 2 and FIG. 3 again. In this embodiment, the key base 300 further includes a second stop portion 330, wherein the elastic member 230 sleeved on the boss 220 is located at the second stop. between the part 330 and the pressing part 212 . When the button 200 is pressed by the user to move the protrusion 220 from the first position A to the second position B, one end of the elastic member 230 is against the second stop portion 330 so that the pressing portion 212 can move from the elastic member 230 The other end compresses the elastic member 230 , thereby deforming the elastic member 230 and accumulating energy for driving the button 200 to reset.

Furthermore, the electronic device 100 includes a circuit board 110 having a trigger portion 112 , the trigger portion 112 faces the key base 300 and is opposite to the boss 220 . When the protruding post 220 is at the second position B, the protruding post 220 will press the trigger part 112, so that the trigger part 112 generates electrode conduction, thereby sending an electronic signal to the central processing unit (not shown) of the electronic device 100 processing, and display the processed signal through a display unit (not shown).

FIG. 4 is a partial schematic view of the button in FIG. 2 at another angle. Please refer to FIG. 4 , in this embodiment, the key body 210 further includes a groove 218 , and the key base 300 (marked in FIG. 1 ) further includes a rib 340 . When assembling the key 200 on the key base 300 , the user needs to align the rib 340 with the groove 218 before installing the key 200 into the key base 300 by moving the rib 340 along the groove 218 . This enables the key 200 to be positioned on the key base 300 through the interfitting ribs 340 and grooves 218 , which has a fool-proof function in assembly to avoid errors during assembly.

FIG. 5 is a partial schematic view of the button in FIG. 2 at another angle. Please refer to FIG. 2 and FIG. 5. In this embodiment, in order to enable the key 200 to be installed on the key base 300 smoothly, the key body 210 also includes a guide 211, and the key base 300 also includes a guide surface 350 ( Marked in FIG. 2 ), the guide member 211 is used to move according to the shape of the guide surface 350 so that the key 200 can be placed in the key base 300 . In this embodiment, the guiding surface 350 is a guiding inclined surface located on the step portion 310 , at this time, the guiding element 211 also has a corresponding inclined surface, so that they can cooperate with each other. Here, the present invention does not limit the appearance of the guide member 211 and the guide surface 350 , which can be changed according to the manufacturing method between the key 200 and the key base 300 .

Please refer to FIG. 2 and FIG. 3 again. On the other hand, in this embodiment, the key body 210 is essentially an elastic body, so the key 200 can be pressed into the key base 300 through the instant deformation of the hook 216 . In addition, it is worth noting that when the user presses the pressing portion 212 of the key 200, the key body 210 will also be deformed, such as being dented downward, so that the protrusion 214 moves from the first position A to the second position B, and compresses the elastic 230 pieces. Once the user no longer applies force to the pressing portion 212, the button body 210 returns to the original unstressed state through the elastic restoring force between it and the elastic member 230, and the protrusion 214 moves from the second position B back to the first position. position a. To sum up, in the button and the electronic device of the present utility model, the seal is pressed between the pressing part and the step part by the button body, so that the gap between the button and the key base can be filled by the seal, so that Prevent foreign objects from entering the key base through this gap. Furthermore, the elastic member is sleeved on the boss and is located between the pressing portion and the second stopper portion, so that the button can be reset by driving the boss after being pressed.

In addition, in order to make the assembly of the keys more smooth, the key body and the key base each have corresponding ribs and grooves, as well as guides and guide surfaces. By cooperating with each other, the user can assemble the keys in the key base with less effort, and achieve the fool-proof function to avoid assembling errors.

Although the utility model has been disclosed as above with the embodiment, it is not intended to limit the utility model. Anyone with ordinary knowledge in the technical field can make some changes without departing from the spirit and scope of the utility model. and retouching, so the protection scope of the present utility model should be defined by the claims as the criterion.
