DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] In order to more comprehensively understand the features and technical content of the embodiments of the present utility model, the implementation of the embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and explanation purposes and are not used to limit the embodiments of the present utility model. In the following technical descriptions, for the convenience of explanation, numerous details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be shown in a simplified manner to simplify the drawings.

[0033] The waterproof button assembly involved in the embodiments of the present invention can be installed in various terminals, such as mobile phones, tablet computers, and watches, etc. The waterproof button assembly involved in the embodiments of the present utility model mainly solves the problem that the installation steps of the waterproof button assembly in the prior art are complex. Below, the waterproof button assembly provided by the present invention will be described in detail through specific embodiments.

[0034] Please refer to Figures 1-4 , the waterproof button assembly disclosed by the present utility model is used to be installed on an electronic device, and includes: a button 7, including a main body 720 and side plates 710 arranged on the edge of the main body 720, and a first limiting portion 712 is arranged on the side plate 710; a button bracket 5, assembled on the button 7, and the button bracket 5 is used to be fixed to the electronic device, and the first limiting portion 712 limits the movement of the button 7 away from the electronic device relative to the button bracket 5; a waterproof pad 4, used to be clamped between the button bracket 5 and the electronic device to form a waterproof seal between the button bracket 5 and the electronic device. By assembling the button 7 and the button bracket 5 in a limited way, and then matching the button bracket 5 with the electronic device, and tightly clamping the waterproof pad 4 between the two, the present utility model optimizes the installation structure of the button 7 on the premise of ensuring the waterproof performance of the waterproof button assembly, making the installation steps of the waterproof button assembly more convenient and facilitating installation and disassembly.

[0035] In this embodiment, the button 7 further includes a button post 701, arranged on one side of the button 7. An installation hole 501 is formed on the button bracket 5, and the size of the installation hole 501 is adapted to the button post 701, and the button post 701 passes through the installation hole 501. The button cover includes a main body 720 and side plates 710, and the side plates 710 are arranged at both ends of the main body 720. Specifically, the button post 701 and the side plates 710 are located on the same side of the main body 720, and the button bracket 5 is installed between the two side plates 710 and is passed through its installation hole 501 by the button post 701. Preferably, the side plate 710 is perpendicularly arranged to the plane where the main body 720 is located.

[0036] Further, in some embodiments, an abutting portion 713 is formed on the other side of the side plate 710. The abutting portion 713 is used to abut against the button bracket 5 to limit the movement of the button 7 deflecting relative to the button bracket 5. After the button post 701 passes through the mounting hole 501, the button bracket 5 can be rotated counterclockwise or clockwise to the buckling direction. After the button bracket 5 rotates to the buckling direction, it abuts against the abutting portion 713 on the inner side wall of the side plate 710 to limit its rotation angle during the rotational installation process of the button bracket 5. Among them, the rotation direction depends on the opening direction of the limiting groove 711 of the side plate 710.

[0037] During the specific installation process, first pass the button bracket 5 through the button post 701 in an inclined direction with respect to the button 7, and then rotate the button bracket 5 through the limiting groove 711 on the side of the side plate 710, so as to rotate and combine the button bracket 5 onto the button 7. At this time, the directions of the button 7 and the button bracket 5 are the same. After the button bracket 5 is assembled onto the button 7, a first limiting portion 712 is provided on the side of the limiting groove 711, and a second limiting portion 502 is provided at the position of the button bracket 5 opposite to the first limiting portion 712, which can limit the button bracket 5 in the axial direction of the button post 701, thereby limiting the button bracket 5 within the button 7.

[0038] In one embodiment, please refer to Figure 2 , a limiting groove 711 is provided on one side of the side plate 710, and a first limiting portion 712 is formed on the side wall of the limiting groove 711. The button bracket 5 is provided with a second limiting portion 502 corresponding to the first limiting portion 712. The first limiting portion 712 and the second limiting portion 502 cooperate to limit the movement of the button 7 away from the electronic device relative to the button bracket 5. Specifically, the two side plates 710 are oppositely arranged at both ends of the body 720, and a limiting groove 711 is respectively provided at the diagonal sides of the two side plates 710. The height of the limiting groove 711 is slightly higher than the height of the bracket to facilitate the button bracket 5 to rotate through the limiting groove 711 during installation. The height of the side plate 710 is higher than the height of the limiting groove 711. Thus, the protruding part still retains part of the side plate 710, forming the side wall of the limiting groove 711, which is called the first limiting portion 712. At the position of the button bracket 5 corresponding to the limiting groove 711, a protruding second limiting portion 502 is provided. When the button bracket 5 is installed in the button 7, the second limiting portion 502 is located in the limiting groove 711. When the button 7 has a tendency to move away from the electronic device relative to the button bracket 5, the second limiting portion 502 will offset in the groove and abut against the side wall of the groove, that is, the first limiting portion 712. Thus, the first limiting portion 712 and the second limiting portion 502 cooperate to be able to limit the movement of the button 7 away from the electronic device relative to the button bracket 5, that is, to assemble the button bracket 5 into the button 7.

[0039] In one embodiment, one end of the side plate 710 away from the body 720 is folded inward to form the first limiting portion 712, thereby limiting the key 7 in a direction away from the electronic device relative to the key bracket 5. Specifically, the inwardly bent portion of the side plate 710 can directly limit the key bracket 5, thereby realizing the limiting function without cooperating with other parts.

[0040] In one embodiment, please refer to Figure 3 The key 7 moves between the first position and the second position. When the key 7 is in the first position, the key 7 is spaced from the electronic device. Specifically, a certain gap is left between the end of the key cover side plate 710 and the electronic device, which is reserved for a stroke for the key 7 to press. When the key 7 is in the second position, the key 7 is pressed, and the key 7 is against the electronic device. By reserving a certain gap to reserve a stroke for the key 7 to press, the key 7 is divided into two states: pressed and released.

[0041] In one embodiment, Figure 2 The button bracket 5 is provided with a third limit portion 503 on the side facing the housing 3, and the third limit portion 503 is used to abut against the electronic device. Specifically, the third limit portion 503 is a plurality of protrusions on the side of the button bracket 5 away from the button cover, and these protrusions abut against the electronic device. The height of the protrusions defines the distance between the button bracket 5 and the electronic device. A silicone pad is sandwiched between the two. The height of the protrusion is slightly less than the thickness of the waterproof pad 4. A certain interference is designed to help ensure the waterproof performance. At the same time, the support provided by the protrusions can prevent the silicone pad from being excessively squeezed and deformed.

[0042] In one embodiment, referring to 1 and 2, the waterproof button assembly further includes an elastic member 6, which is sandwiched between the button 7 and the button bracket 5. The elastic member 6 is elastic, so that the button 7 tends to move away from the electronic device, that is, the elastic member 6 plays a rebound role, and the button 7 can reciprocate on the button bracket 5 when pressed, and the button 7 is not easy to be skewed or stuck when pressed. It should be noted that the elastic member 6 includes but is not limited to being made of foam material. The shape of the elastic member 6 can be a long elastic sheet passing through the button column 701 as shown in the figure, or it can be a ring, a dot, or other shapes dispersed between the button 7 and the button bracket 5.

[0043] In one embodiment, the waterproof pad 4 has a recess 401, and the end of the key post 701 abuts against the recess 401. The waterproof pad 4 is made of an elastic material, so that the key 7 has a tendency to move away from the electronic device. Thus, in some embodiments, due to the elasticity of the waterproof pad 4 itself, the key 7 can be reset by relying on its elasticity, and there is no need to additionally provide an elastic member 6. In other embodiments, the elastic member 6 and the silica gel pad are used in cooperation. Such a design can optimize the feel of the key 7, and the feel can be adjusted by adjusting the hardness, softness, thickness of the silica gel, while ensuring the waterproof performance of the key 7 and optimizing the feel of the key 7. It should be noted that the material of the waterproof pad 4 in this embodiment includes but is not limited to silica gel material.

[0044] In a specific embodiment, the key 7 is made of aluminum processed by CNC. The structural space limitation is relatively high in terms of plastic structure strength. It should be noted that the material of the key 7 is not limited to aluminum processed by CNC, and it can also be other materials that are easy to process and have high strength.

[0045] The waterproof key assembly provided in the first aspect of the present utility model limits and assembles the key 7 and the key bracket 5 together, and then makes the key bracket 5 cooperate with the electronic device, and tightly clamps the waterproof pad 4 between the two, so as to optimize the installation structure of the key 7 on the premise of ensuring the waterproof performance of the waterproof key assembly, making the installation steps of the waterproof key 7 assembly simpler and facilitating installation and disassembly.

[0046] In the second aspect, the present utility model also discloses an electronic device, including a housing 3 and a waterproof key assembly.

[0047] In one embodiment, please refer to Figure 1 , the housing 3 is provided with a through hole 301, and the recess 401 and the end of the key post 701 pass through the through hole 301. Specifically, the waterproof pad 4 is clamped between the bottom wall of the key groove and the key bracket 5. A through hole 301 is provided in the center of the bottom wall of the key groove. The waterproof pad 4 has a protrusion adapted to the shape of the through hole 301. Since the waterproof pad 4 is a film-like structure, the other side of the protrusion is a recessed structure. The end of the key post 701 abuts against the recess 401 of the waterproof pad 4, that is, the protrusion of the waterproof pad 4 and the end of the key post 701 pass through the through hole 301.

[0048] In one embodiment, please refer to Figure 1 、 3, 4. On the side of the housing 3 facing away from the button 7, an electronic control board is fixed. When the button 7 is in the second position, the end of the button post 701 abuts against the electronic control board through the waterproof pad 4. In some embodiments, the electronic device further includes an electronic control board bracket 2. The electronic control board bracket 2 is fixed inside the housing 3 by screws 1 or other means. The screw 1 passes through the housing 3 to fix the electronic control board bracket 2 and the button bracket 5 on both sides of the housing 3 respectively. The electronic control board is clamped between the electronic control board bracket 2 and the housing 3. Among them, the electronic control board is attached to the center of the electronic control board bracket 2 by an adhesive. The end of the button post 701 abuts against the electronic control board through the recess 401 of the elastic waterproof pad 4. An induction switch corresponding to the trigger is provided on the electronic control board. Therefore, when the button 7 is pressed, the button post 701 can trigger the corresponding switch on the electronic control board to achieve control.

[0049] In one embodiment, please refer to Figure 1 , 3 , the housing 3 is provided with a button groove so that when the button 7 switches between the first position and the second position, the side plate 710 is in guiding cooperation with the button 7 groove along the moving direction of the button 7, thereby limiting the pressing stroke of the button 7 and preventing it from shifting.

[0050] In one embodiment, please refer to Figure 1 , the button bracket 5 is fixed to the housing 3 by screws 1. Screw holes 302 are also provided on both sides of the through hole 301. The screw 1 extends into the button groove from the inside of the housing 3 and is connected to the button bracket 5, thereby fixing the button assembly on the housing 3.

[0051] The electronic device provided in the second aspect of the present utility model uses a waterproof button assembly with excellent waterproof performance to limit and assemble the button 7 and the button bracket 5 together, and then make the button bracket 5 cooperate with the electronic device, and tightly clamp the waterproof pad 4 between the two. Thus, on the premise of ensuring the waterproof performance of the waterproof button assembly, the installation structure of the button 7 is optimized, the installation steps of the waterproof button assembly are made more convenient, the installation and disassembly of the device are facilitated, its service life is improved, and the use experience of the electronic device is optimized.
