Referring to FIG. 5A , in this embodiment, the first button 116 includes a push portion 117 extending into the first housing 112 . The position of a first central axis A1 of the pushing portion 117 is shifted from the position of a second central axis A2 of the first trigger switch 122 . In this embodiment, the position of a first central axis A1 of the push portion 117 is shifted from the position of a second central axis A2 of the first trigger switch 122 , which represents the push portion 117 of the first button 116 and the first trigger switch 122 There is an offset segment difference.

In other embodiments, the first trigger switch 122 and the push portion 117 of the first button 116 may not be on the same plane, for example, the push portion 117 of the first button 116 is significantly lower or higher than the circuit board 120, so that the first button The pushing portion 117 of 116 cannot directly press the first trigger switch 122 when pressed.

Therefore, in the present embodiment, the electronic device 100 adopts the design that the elastic arm 132 is located between the pushing portion 117 and the first trigger switch 122 .

The spring arm 132 triggers the first trigger switch 122 . Therefore, even if the first button 116 is not well aligned with the first trigger switch 122, the first trigger switch 122 can still be triggered well.

In addition, it can be seen from FIG. 5A and FIG. 5B , in this embodiment, the pushing portion 117 continuously abuts on the end of the elastic arm 132 away from the covering portion 134 , so that the first button 116 can stably push the elastic arm 132 to make the elastic arm 132 be pushed. The arm 132 pushes the first trigger switch 122 . Of course, in other embodiments, the push portion 117 may also abut against the end of the elastic arm 132 away from the cover portion 134 after the first button 116 is pushed, which is not limited by the drawings.

Furthermore, the circuit board 120 of this embodiment can be a main circuit board, and the first trigger switch 122 is disposed on the edge of the circuit board 120 . The electronic device 100 of this embodiment does not need to push the first trigger switch 122 to the pushing portion 117 of the first button 116 on the premise that the circuit board 120 is not aligned with the pushing portion 117 of the first button 116 . The trigger switch 122 is disposed on the additional secondary circuit board, so that the first trigger switch 122 is positioned on the push portion 117 of the first button 116 .

Compared with the design that also requires a secondary circuit board, in this embodiment, since the first trigger switch 122 can be directly disposed on the edge of the main circuit board 120, the overall cost and the number of components can be reduced, and there is no need to provide Extra wiring to connect the primary circuit board to the secondary circuit board.

In addition, it should be noted that the electronic device 100 of the present embodiment uses the original inner shell 130, and the elastic arm 132 is designed on the inner shell 130, and no additional elastic sheet structure is required, and the design can be simplified.

In addition, since the material of the elastic arm 132 is the same as that of the inner shell 130, both are hard materials. Compared with soft materials such as rubber, which absorb the feedback feeling of pressing, the feedback feeling of the first trigger switch 122 when pressed can be transmitted to the first button 116 through the hard elastic arm 132, and the feedback is given to the user to know that the pressing has been completed correctly.

In addition, as can be seen from FIG. 5A , one of the first casing 112 and the second casing 114 includes an engaging groove 113 , and the other includes a convex portion 115 extending into the engaging groove 113 . In addition, the electronic device 100 further includes a waterproof glue 118 located in the joint groove 113 . The joint groove 113 is, for example, a glue groove, which can accommodate the waterproof glue 118 , and the convex portion 115 extends into the joint groove 113 and is located in the joint groove 113 The waterproof gel 118 will adhere to the convex portion 115 . Therefore, the electronic device 100 can have a good waterproof effect.

FIG. 6 is a schematic diagram of another viewing angle of the electronic device of FIG. 1 . FIG. 7 is a schematic diagram of removing the second button of FIG. 6 . FIG. 8 is a schematic diagram of another viewing angle of the second housing and the elastomer. FIG. 9 is a schematic cross-sectional view of FIG. 6 . It should be noted that, in FIGS. 7 and 8 , two opposite sides of the elastic body can be seen respectively.

Referring to FIGS. 6 to 9 , in this embodiment, the electronic device 100 further includes two second buttons 119 located in the second casing 114 and adjacent to each other, and two second triggers corresponding to the positions of the two second buttons 119 The switch 150 ( FIG. 9 ) and an elastic body 140 ( FIG. 9 ) located between the two second trigger switches 150 and the two second buttons 119 . As shown in FIG. 8 , the elastic body 140 includes two contact portions 142 corresponding to the positions of the two second trigger switches 150 .

As shown in FIG. 9 , in this embodiment, when the second button 119 is pressed, it will be pressed against the contact portion 142 of the elastic body 140 , and the contact portion 142 will be deformed and pressed against the second trigger switch 150 , so that the second trigger switch 150 is pressed. Switch 150 is activated.

That is to say, in this embodiment, when one of the second buttons 119 is pressed, one of the contact portions 142 on the elastic member is pressed against the corresponding second trigger switch 150 . Similarly, when the other second button 119 is pressed, the other second trigger switch 150 is also pressed through the other contact portion 142 on the same elastic member.

Since the size of the electronic device 100 is limited to a certain extent, the two second buttons 119 are quite close, and correspondingly the two second trigger switches 150 are quite close. In this embodiment, the distance D between the two second trigger switches 150 is 11 Between mm and 12 mm.

Since the two second trigger switches 150 are quite close together, the two contact portions 142 are formed on the same elastic body 140 . In order to avoid the linkage between the two contact portions 142, when one of the buttons is pressed, both the second trigger switches 150 are triggered.

As shown in FIG. 8 , the elastic body 140 further includes a blocking structure 144 located between the two contact portions 142 . In this embodiment, the blocking structure 144 is a wall protruding toward the space between the two trigger switches. The arrangement of the blocking structure 144 can help to avoid the linkage between the two contact portions 142 . When one of the buttons is pressed, one of the contact portions 142 moves, and the blocking structure 144 can reduce the probability of this motion being transmitted to the other contact portion 142 , thereby effectively preventing both the second trigger switches 150 from being triggered.

It can be seen from FIGS. 7 and 9 that the blocking structure 144 is hollow and recessed on a surface of the elastic body 140 facing the two second buttons 119 to reduce material and weight. Of course, in other embodiments, the blocking structure 144 may not be hollow.

In addition, compared to each second button 119 having an independent elastic member, in this embodiment, the two second buttons 119 share a single elastic member, which also has the advantage of simplifying the assembly process and the number of parts.

To sum up, since the position of the first central axis of the push portion of the first button of the electronic device is shifted from the position of the second central axis of the first trigger switch, the first trigger switch may not be located at the push portion of the first button. on the moving path. The electronic device of the novel creation utilizes the elastic arm formed on the inner shell, and the elastic arm is located between the push portion and the first trigger switch, so that the first button can trigger the first trigger switch through the elastic arm. Therefore, even if the first button is not well aligned with the first trigger switch, the first trigger switch can still be triggered well.
