[0039] As described in the background section, button assemblies are components widely used in various electronic devices and mechanical devices. In related technologies, button assemblies include buttons, button housings, and circuit boards. The circuit board is installed inside the button housing, and part of the button's structure is housed within the button housing to cooperate with the circuit board. Another part of the button's structure is located outside the button housing for user operation. During button installation, the portion of the button's structure that needs to extend outside the button housing is pushed outwards from back to front. However, this installation method exposes the front of the button housing through the installation gap, thus preventing the button assembly from achieving waterproofing.

[0040] Reference Figures 1 to 7 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a button assembly. The button assembly includes a button portion 100, a mounting portion 200, and a control portion 300. The mounting portion 200 has a mounting space 230 and a mounting surface 222. The control portion 300 is disposed within the mounting space 230. The mounting surface 222 is located outside the mounting space 230 and is provided with a mounting hole 2221 communicating with the mounting space 230. The button portion 100 passes through the mounting hole 2221 for cooperating with the control portion 300. The mounting surface 222 is provided with a waterproof structure 240, which surrounds the mounting hole 2221 and protrudes in a direction away from the mounting hole 2221.

[0041] In this embodiment, the button part 100 is a button that can be used by the user; the mounting part 200 is a mounting shell or mounting box, the mounting space 230 is a closed space, and the mounting hole 2221 is a through hole that extends from the mounting surface 222 into the mounting space 230; the control part 300 is a control circuit board, which is fixedly installed in the mounting space 230; the waterproof structure 240 is a waterproof ring, which is made of a rigid material (such as metal or rigid plastic) and is integrally molded with the mounting part 200. It can be understood that the waterproof structure 240 can also be made of a soft material (such as silicone or rubber).

[0042] In this application, the waterproof structure 240 is arranged around the mounting hole 2221, which not only effectively prevents liquid on the mounting surface 222 from entering the mounting space 230 through the mounting hole 2221, but also effectively prevents liquid from contacting the control unit 300 located in the mounting space 230, reducing the possibility of the control unit 300 malfunctioning due to moisture, improving the waterproof performance of the button assembly, and extending the service life of the control unit 300. At the same time, compared with using complex sealing gaskets or sealants, the waterproof structure 240 simplifies the installation process, reduces installation difficulty, and improves installation efficiency.

[0043] Reference Figures 4 to 7 In one embodiment, the mounting surface 222 is located above the mounting space 230 in the direction of gravity; the mounting surface 222 is provided with a drain hole 2222, and the mounting part 200 also has a drain structure 250, which communicates with the drain hole 2222 and extends to the outside of the mounting space 230 to guide the liquid on the mounting surface 222 to flow to the outside of the mounting space 230.

[0044] In this embodiment, the drain hole 2222 is a hole extending toward the mounting space 230, and the drain structure 250 is a drain pipe. The drain structure 250 is connected to the end of the drain hole 2222 that is away from the mounting surface 222.

[0045] Since the mounting surface 222 is above the mounting space 230, when liquid falls onto the mounting surface 222, the liquid will naturally flow to the drain hole 2222 under the action of gravity. At the same time, since the drainage structure 250 is connected to the drain hole 2222, the drainage structure 250 will guide the liquid on the mounting surface 222 to the outside of the mounting space 230 in a timely manner, avoiding the accumulation of liquid on the mounting surface 222. By using the drain hole 2222 and the drainage structure 250, the risk of liquid seeping into the mounting space 230 through gaps such as the mounting hole 2221 can be further reduced, which helps to further enhance the waterproof capability of the button assembly.

[0046] Reference Figures 4 to 7In one embodiment, the drainage structure 250 is arranged along the direction of gravity and extends through the installation space 230 to the outside of the installation space 230.

[0047] The drainage structure 250, which is set along the direction of gravity, can make the greatest use of gravity to allow the liquid to be discharged quickly and smoothly under its own gravity. Compared with the drainage design in the direction of non-gravity, the drainage structure 250 set along the direction of gravity significantly improves the drainage speed, reduces the time that the liquid stays on the mounting surface 222, and further avoids the accumulation of liquid on the mounting surface 222.

[0048] Furthermore, the drainage structure 250 extends through the installation space 230 and beyond the installation space 230, minimizing the length of the drainage structure 250. This not only helps to form a complete and direct drainage path, eliminating possible drainage angles and ensuring thorough drainage, but also helps to reduce manufacturing costs.

[0049] Reference Figures 4 to 7 In one embodiment, the mounting surface 222 is provided with a guide slope 2223, which is arranged around the drain hole 2222 and gradually tilts towards the drain hole 2222 along the direction of gravity.

[0050] In this embodiment, the guide ramp 2223 is a guide ring surface. The guide ramp 2223 not only effectively guides the liquid falling on the mounting surface 222 to the drain hole 2222 using gravity, reducing the possibility of liquid accumulation on the mounting surface 222; at the same time, compared with a flat design, the inclination angle of the guide ramp 2223 allows the liquid to gain a certain acceleration under the action of gravity, thereby enabling the liquid to flow to the drain hole 2222 faster, which helps to speed up the overall drainage speed.

[0051] Reference Figures 4 to 7 In one embodiment, the mounting part 200 includes a mounting body 210 and a mounting member 220. The mounting body 210 has a first mounting area 211, and the mounting member 220 has a second mounting area 221. The second mounting area 221 communicates with the first mounting area 211 and forms a mounting space 230. The mounting body 210 has an operating surface 212, and the operating surface 212 is provided with a mounting groove 2121, which is a through groove arranged along the direction of gravity. The button part 100 and the mounting surface 222 are both provided in the mounting member 220, and the mounting member 220 is disposed in the mounting groove 2121.

[0052] In this embodiment, the first installation area 211 is a closed area, and the second installation area 221 is a closed area. Part of the structure of the control unit 300 is installed in the first installation area 211, and another part of the structure of the control unit 300 is installed in the second installation area 221. The installation unit 200 is fixedly installed in the installation groove 2121, and all its structures are located in the installation groove 2121. It can be understood that the installation component 220 may also have part of its structure disposed in the installation groove 2121, and another part of its structure disposed outside the installation groove 2121.

[0053] The mounting groove 2121 provides some protection for the mounting component 220, preventing it from directly bearing external impact forces and reducing the risk of damage due to collisions. The mounting groove 2121 is positioned along the direction of gravity, ensuring that liquid falling between the mounting component 220 and the groove wall flows quickly out of the groove under its own weight. This prevents liquid from accumulating between the mounting component 220 and the groove wall and flowing into the mounting space 230, effectively improving the waterproof performance of the button assembly. Furthermore, the mounting groove 2121 is located on the operating surface 212, ensuring that liquid falling from above or splashing onto the operating surface 212 first, rather than falling directly onto the mounting surface 222, thus preventing liquid from flowing into the mounting space 230 through the mounting hole 2221.

[0054] Reference Figures 4 to 7 In one embodiment, the operating surface 212 is provided with a guide slope 2122, which is arranged around the opening of the mounting groove 2121 and gradually tilts towards the mounting groove 2121 along the direction of gravity.

[0055] In this embodiment, the guide slope 2122 is a guide ring surface. The guide slope 2122 not only effectively guides the liquid falling on the operating surface 212 to flow into the mounting groove 2121 by gravity, reducing the possibility of liquid accumulation on the operating surface 212; at the same time, compared with the planar design, the inclination angle of the guide slope 2122 allows the liquid to gain a certain acceleration under the action of gravity, so that the liquid can flow to the mounting groove 2121 more quickly, which helps to speed up the overall drainage speed.

[0056] Reference Figure 1 , Figure 2 as well as Figures 4 to 7 In one embodiment, a connector 260 is provided between the mounting member 220 and the mounting body 210, and the connector 260 is disposed in the mounting groove 2121; a drainage gap 270 is provided between the mounting member 220 and the mounting body 210.

[0057] In this embodiment, the connector 260 is a connecting plate or connecting block arranged circumferentially along the mounting groove 2121. The connector 260 is integrally formed with the mounting body 210 and with the mounting component 220. Furthermore, the entire structure of the connector 260 is located within the mounting groove 2121. It can be understood that a portion of the structure of the connector 260 may be located within the mounting groove 2121, while another portion may be located outside the mounting groove 2121. In addition, the drainage gap 270 is part of the mounting groove 2121, and its length projected onto the horizontal plane through the connector 260 is less than the circumference of the groove opening of the mounting groove 2121 projected onto the horizontal plane.

[0058] The connector 260 serves as a connection, allowing the mounting component 220 to be securely installed on the mounting body 210. The drainage gap 270 provides a dedicated drainage channel for liquid between the mounting body 210 and the mounting component 220, preventing liquid from accumulating between them and improving the overall waterproof performance of the button assembly.

[0059] Reference Figures 1 to 7 In one embodiment, the operating surface 212 is higher than the upper surface of the connector 260 in the direction of gravity. This structural design not only facilitates effective protection of the connecting surface but also helps reduce the size of the mounting portion 200 in the direction of gravity, thereby reducing the overall volume of the button assembly.

[0060] Reference Figures 4 to 7 In one embodiment, the mounting surface 222 is provided with a protective structure 280, which is disposed around the mounting surface 222 and protrudes in a direction away from the mounting hole 2221; in the direction of gravity, the operating surface 212 is higher than the upper surface of the protective structure 280.

[0061] In this embodiment, the protective structure 280 is a protective ring, and the protective structure 280 and the mounting part 220 are integrally formed; it can be understood that the protective structure 280 can also be fixedly installed on the mounting surface 222 by welding, gluing or other connection methods.

[0062] The protective structure 280 is arranged around the mounting surface 222, which not only prevents liquid flowing from the operating surface 212 into the mounting groove 2121 from easily flowing onto the mounting surface 222, forming a preliminary barrier against liquid; it also protects the mounting surface 222 and the components mounted on it, preventing external objects from directly impacting the mounting surface 222 and the mounting hole 2221. The operating surface 212 is higher than the upper surface of the protective structure 280. This structural design not only facilitates effective protection of the protective structure 280, but also helps to reduce the size of the mounting part 200 in the direction of gravity, thereby reducing the overall volume of the button assembly.

[0063] Reference Figures 3 to 7 To further reduce the size of the mounting part 200 in the direction of gravity, the lower surface of the mounting body 210 and the lower surface of the mounting component 220 are kept flush.

[0064] Reference Figures 1 to 9 In one embodiment, the button unit 100 includes a press button 110, which includes a detachably connected press keycap 111 and a press mating body 112. The press keycap 111 is located on the side of the press mating body 112 away from the mounting space 230. The press mating body 112 passes through the mounting hole 2221 and is used to move closer to or away from the control unit 300 in a preset direction.

[0065] In this embodiment, the pressing engagement body 112 is a spring arm. A limiting groove is provided on the surface of the pressing engagement body 112 away from the installation space 230. A portion of the structure of the pressing keycap 111 is inserted into the limiting groove, and the pressing keycap 111 is prevented from rotating within the limiting groove by contacting the groove wall. The pressing keycap 111 can be detachably connected to the pressing engagement body 112 by a snap-fit ​​method or a screw connection method. The control unit 300 includes a control body and conductive contacts. The conductive contacts are fixedly installed on the control body. The preset direction is parallel to the direction of gravity. Specifically, the pressing engagement body 112 moves closer to or away from the conductive contacts along the preset direction to contact or separate from the conductive contacts.

[0066] When the press button 110 is installed onto the mounting part 200, the press mating body 112 is inserted from the mounting space 230 into the mounting hole 2221, and then the press keycap 111 is installed from outside the mounting space 230 onto the press mating body 112. The detachable connection between the press keycap 111 and the press mating body not only allows the press keycap 111 and the press mating body to be installed separately onto the mounting part 200, reducing installation difficulty and improving installation efficiency; at the same time, when the press button 110 malfunctions, by separating the press keycap 111 from the press mating body 112, maintenance personnel can repair or replace the press keycap 111 or the press mating body 112 separately, reducing maintenance costs and difficulty.

[0067] Reference Figure 4 , Figure 5 , Figure 8 as well as Figure 9 In one embodiment, one of the keycap 111 and the pressing mating body 112 is provided with a connecting hook 1111, which is an elastic structure, and the other is provided with a connecting groove 1121. The keycap 111 is detachably installed on the pressing mating body 112 through the engagement of the connecting hook 1111 and the connecting groove 1121.

[0068] In this embodiment, the connecting hook 1111 is made of elastic material such as plastic or rubber; the keycap 111 can be detachably installed on the pressing body 112 by hooking it in the connecting slot 1121 through the connecting hook 1111, or it can be detachably installed on the pressing body 112 by passing the connecting hook 1111 through the connecting slot 1121 and hooking it to the surface outside the connecting slot 1121.

[0069] During assembly, the assembler only needs to align the connecting hook 1111 with the connecting slot 1121 and then press the connecting hook 1111 into the connecting slot 1121 to complete the connection between the keycap 111 and the pressing mating body 112. No additional tools or complicated procedures are required, greatly improving assembly efficiency and saving assembly time and labor costs. Furthermore, the elastic connecting hook 1111 generates a certain elastic force when engaging with the connecting slot 1121, which not only makes the connection between the keycap 111 and the pressing mating body 112 tighter and more stable, but also provides a certain degree of cushioning and shock absorption during the pressing of the key 110.

[0070] Reference Figure 4 , Figure 5 , Figure 8 as well as Figure 9 In one embodiment, a connecting hook 1111 is disposed on the keycap 111; a connecting groove 1121 is disposed on the surface of the pressing mating body 112 away from the installation space 230, and extends along a preset direction to the surface of the pressing mating body 112 near the installation space 230; after the keycap 111 is installed onto the pressing mating body 112, the main body of the connecting hook 1111 passes through the connecting groove 1121, and the hook portion of the connecting hook 1111 extends outside the connecting groove 1121 and hooks onto the surface of the pressing mating body 112 near the installation space 230.

[0071] In this embodiment, the connecting hook 1111 and the keycap 111 are integrally formed parts, and the connecting hook 1111 is disposed on the surface of the keycap 111 near the mounting space 230; the connecting slot 1121 passes through the limiting slot.

[0072] On the one hand, the main body of the connecting hook 1111 passes through the connecting slot 1121, and the hooking part of the connecting hook 1111 extends outside the connecting slot 1121 and hooks onto the surface of the pressing mating body 112 near the installation space 230, forming a structure similar to a "barb". This structure can limit the pressing keycap 111 and the pressing mating body 112 in multiple directions, greatly enhancing the connection stability between the two and effectively preventing the pressing keycap 111 and the pressing mating body 112 from separating during frequent pressing.

[0073] On the other hand, the connection hook 1111 is set on the keycap 111, and the connection slot 1121 is set on the keycap 112. Compared with the solution where the connection hook 1111 is set on the keycap 112 and the connection slot 1121 is set on the keycap 111, it helps the assembly personnel to see more intuitively the process of aligning the connection hook 1111 with the connection slot 1121, which facilitates precise operation.

[0074] Reference Figures 1 to 4 , Figure 5 , Figure 8 as well as Figure 9 In one embodiment, there are multiple keycaps 111, which are spaced apart in a direction parallel to a preset direction, and the multiple key bodies are integrally formed.

[0075] In this embodiment, multiple push buttons 110 are arranged at circumferential intervals along the mounting surface 222. The multiple push buttons 110 enrich the button functions of the button assembly.

[0076] Reference Figures 1 to 4 , Figure 5 , Figure 8 as well as Figure 9 In one embodiment, the button part 100 further includes a rotary button 120, which is located on one side of the press button 110. The rotary button 120 passes through the mounting hole 2221 and is rotatably disposed on the mounting surface 222 about a direction parallel to a preset direction.

[0077] In this embodiment, the rotary button 120 is coaxially arranged with the mounting surface 222 in the circumferential direction, and multiple push buttons 110 are spaced apart along the circumferential direction of the rotary button 120. The control unit 300 also includes an encoder or potentiometer, which is mounted on the control body. The rotary button 120 works in conjunction with the control body via the encoder or potentiometer. The rotary button 120 enriches the button functions of the button assembly.

[0078] Reference Figures 1 to 9 According to another aspect of this application, embodiments of this application also provide an electronic device, which includes a device body and the aforementioned button assembly, wherein the button assembly is disposed on the device body and electrically connected to the device body.
