[0035] The utility model provides an electronic device, which is a device that uses a toggle switch 3 to achieve gear shifting, such as an electric toy, an audio device, or a wireless microphone receiver, etc. The utility model takes the electronic device as a wireless microphone receiver as an example to continue to introduce the technical solution and technical effects.

[0036] The electronic device of the utility model comprises a housing 1, a circuit board 4, a toggle switch 3 and a key component 2.

In other words, the box body 11 and the cover body 12 enclose a receiving cavity 1a for receiving electronic components. Of course, the structure of the housing 1 is not limited to that described herein.

[0037] The toggle switch 3 and the circuit board 4 in the utility model are located in the accommodating chamber 1a of the housing 1, and the toggle switch 3 can be mounted on the circuit board 4 by SMT. The toggle switch 3 is mainly used to trigger the corresponding functional circuit on the circuit board 4 to realize the gear shifting function. The toggle switch 3 can be a two-gear toggle switch, a three-gear toggle switch, or a toggle switch with more gears.

[0038] The key component 2 in the present invention includes a main body 20 and an operating part 21. The main body 20 is located inside the accommodating cavity 1a. The operating part 21 is connected to the main body 20. The operating part 21 and the main body 20 can be an integral structure. The operating part 21 can extend to the outside of the housing 1 through the key through hole 11a on the housing 1 to facilitate manual operation by the user. The key through hole 11a is usually located on the peripheral wall 112 of the housing 1. The size and shape of the key through hole 11a can be determined according to the size and shape of the operating part 21, which is not limited in this article.

[0039] In the present invention, the main body 20 further includes a toggle portion, which can be limitedly connected with the toggle switch 3 to toggle the toggle switch 3 to move back and forth, that is, when the user operates the operating portion of the key component 2, under the limit action of the toggle portion and the toggle switch 3, the key component 2 can drive the toggle switch 3 to operate to select the functional circuit. The toggle portion can be a groove 22, and the cantilever end 31 of the toggle switch 3 extends into the groove 22, and the two groove side walls of the groove 22 are used to abut against the cantilever end 31 of the toggle switch 3 to drive the toggle switch 3 to operate.

[0040] In the utility model, the shell 1 has a first limit portion, and the main body 20 also includes a second limit portion. The first limit portion cooperates with the second limit portion to limit the movement of the main body in the direction toward the toggle switch 3. That is to say, through the cooperation of the first limit portion and the second limit portion, the movement of the main body toward the toggle switch 3 can be limited, or the main body 20 is only allowed to move toward the toggle switch 3 within a predetermined range, that is, the movement displacement of the main body 20 toward the toggle switch 3 is limited.

[0041] Compared with the current technology, the housing 1 and the button component 2 of the electronic device of the utility model are respectively provided with a first limit portion and a second limit portion, and the first limit portion and the second limit portion cooperate to limit the movement of the button component 2 in the direction of the toggle switch 3, so that when the button component 2 is subjected to a large external force, the button component 2 will not hit the toggle switch 3, thereby reducing the risk of functional failure of the toggle switch 3.

[0042] In a specific embodiment, the bottom wall 111 of the housing 1 is provided with a slide groove 11b, and the main body 20 has a convex body 23 that slidably cooperates with the slide groove, that is, the first limiting portion is the slide groove, and the second limiting portion is the convex body 23. Of course, the main body can also be provided with a slide groove, and the bottom wall 111 of the housing 1 is provided with a convex body 23, and the convex body 23 cooperates with the slide groove.

[0043] In this embodiment, one of the first limiting portion and the second limiting portion is a slide groove, and the other is a protrusion 23 slidably matched with the slide groove. The protrusion 23 and the slide groove 11b have simple structures and are easy to implement.

[0044] In a specific embodiment, a first protrusion 113 is disposed on the inner wall surface of the bottom wall 111 of the box body 11 , a slide groove 11 b is formed between the first protrusion 113 and a portion of the peripheral wall 112 of the box body 11 , and the key through hole is located on the peripheral wall 112 .

[0045] In this embodiment, a first protrusion 113 is provided on a local inner wall surface of the bottom wall 111 of the box body 11. On the one hand, the overall thickness of the bottom wall 111 of the box body 11 can be reduced, and the overall weight of the box body 11 can be reduced. On the other hand, the first protrusion 113 can also improve the use strength of the box body 11.

[0046] In order to facilitate the protrusion 23 to slide into the sliding groove formed by the first protrusion 113 and the peripheral wall 112, guide surfaces can be set on the surfaces opposite to each other of the first protrusion 113 and the protrusion 23. For example, a guide slope 231 is set on the surface of the first protrusion 113 facing the protrusion 23. The farther from the bottom wall 111, the greater the distance between the guide slope 231 and the peripheral wall 112 opposite to it. The surface of the protrusion 23 facing the first protrusion 113 can also be a guide surface 113a. The guide surface can be an inclined surface or a curved surface, as long as the first protrusion 113 can slide smoothly into the sliding groove.

[0047] In this embodiment, the guide slope 231 is processed on the first protrusion 113, so as to avoid the slope of the guide surface 113a processed by the protrusion 23 and avoid the problem of poor light and shadow appearance of the shell 1.

[0048] In order to take into account the flexibility of the button component 2 and reduce the friction, at least one protrusion 232 may be provided on the first protrusion 113 , and the protrusion 232 is in abutment contact with the first protrusion 113 .

[0049] In a specific embodiment, a groove 22 is provided on the side of the main body 20 facing the toggle switch 3, the groove extends in a direction perpendicular to the circuit board 4, and passes through the end surface of the main body facing the cover 12, that is, the groove 22 passes through the upper end surface of the main body. The groove 22 includes two groove side walls and a groove bottom wall 111 connecting the two groove side walls, the toggle portion includes two groove side walls, and the cantilever end of the toggle switch 3 is located between the two groove side walls.

[0050] In this embodiment, the first protrusion 113 and the groove 22 are respectively located at two opposite ends of the key component 2, the first protrusion 113 is located at the lower end, and the groove 22 is located at the upper end. When the electronic device in this embodiment is assembled, the toggle switch 3 and the circuit board 4 can be pre-assembled into one at other stations. After the key component 2 is installed in the housing 1, the pre-assembled toggle switch 3 and the circuit board 4 are installed together inside the housing 1. During assembly, the cantilever end of the toggle switch 3 slides from the groove opening on the upper end surface of the main body into the groove 22. This structure can improve the flexibility of assembling various components of the electronic device, and the overall spatial modeling selectivity of the electronic device is also greatly improved.

[0051] In a specific embodiment, the first limiting portion also includes a second protrusion 121 arranged on the inner wall of the cover body 12, the main body has an extension portion extending toward the cover body 12, and the second limiting portion includes an extension portion, which is located between the second protrusion 121 and the surrounding wall 112. In this embodiment, the upper end of the button component 2 is further provided with an extension portion, and the cover body 12 can limit the extension portion from moving the button component 2 toward the toggle switch 3. In this way, the lower end and the upper end of the button component 2 are both provided with the second limiting portion, which makes the restriction on the button component 2 more reliable, the force on the button component 2 is relatively uniform, and it is also beneficial to the installation stability of the button component 2.

[0052] In a specific embodiment, there is a space between the circuit board 4 and the peripheral wall 112 to avoid the second protrusion 121 and / or the extension. That is, in this embodiment, only the second protrusion 121 or the extension can be located between the circuit board 4 and the peripheral wall 112, so that the avoidance space between the circuit board 4 and the peripheral wall 112 can be relatively small, which is conducive to the miniaturization design of the electronic device. Of course, considering the use strength of each component, the second protrusion 121 and the extension can be located between the circuit board 4 and the peripheral wall 112 at the same time, so that the matching area of ​​the two is relatively large.

[0053] In a specific embodiment, the groove 22 includes a first section located at the extension part 221, that is, along the length direction of the groove 22, the groove 22 includes a first section and a second section connected, the first section is located at the extension part, and the second section is used to cooperate with the toggle switch 3. The height of the groove side wall of the first section is less than the height of the groove side wall at the position (second section) where the toggle switch 3 is located. The groove side wall of the first section is defined as the first groove side wall 2211, and the groove side wall of the second section is defined as the second groove side wall 222. The second protrusion 121 cooperates with the two groove side walls of the first section to limit. In this embodiment, the groove 22 extends to the upper end surface of the extension part 221. On the one hand, the setting of the extension part does not hinder the setting of the groove, and it is convenient for the processing of the groove. On the other hand, the weight of the key component 2 can be reduced as much as possible under the premise of meeting the use strength of the extension part.

[0054] In the above-mentioned embodiments, at least one support platform 1161 is provided on the inner wall of the housing 1, and the circuit board 4 is supported and connected to the support platform 1161. The circuit board 4 can be fixed to the support platform 1161 by screws and other components. The support platform 1161 can be formed by a structure fixed to the peripheral wall 112 and / or the bottom wall 111 of the box body 11. The utility model shows that the box body 11 includes a support column 116 integrally formed with the bottom wall 111 and the peripheral wall 112, and the support platform 1161 is the upper end surface of the support column. Of course, the support platform 1161 can also be formed by a component that is separately formed from the box body 11. The toggle switch 3 is connected to the side of the circuit board 4 facing the bottom wall 111, that is, the toggle switch 3 is connected to the lower side of the circuit board 4.

[0055] In this embodiment, the circuit board 4 is close to the opening of the box body 11, which is convenient for installation and maintenance.

[0056] In order to improve the installation efficiency of the circuit board 4, in a specific embodiment, the electronic device further includes a positioning column 115, which can be fixed to the inner wall of the housing 1 or the support platform 1161.
