Technical Field
[0001] This utility model relates to the field of waterproof button technology for walkie-talkies, and in particular to a waterproof button structure for walkie-talkies that does not require glue. Background Technology
[0002] In daily life, walkie-talkies may also be used in rainy or humid environments. A waterproof design can meet the user's needs in various complex environments, improve the user experience, and ensure the walkie-talkie continues to function normally in these conditions. For the waterproofing of the side buttons on walkie-talkies, adhesive and sealing rings are usually used. However, as the walkie-talkie is used over time, the adhesive and sealing rings gradually age, causing the waterproofing effect of the buttons to deteriorate. Adhesive is usually applied to silicone buttons from the outside, a method that requires a dispensing process. This dispensing process is prone to excess adhesive, affecting the product's appearance and causing problems on the production line. Internal excess adhesive can cause the tactile lever inside the button to stick, leading to button travel jamming and malfunction. Therefore, it is necessary to optimize and improve the waterproofing solution for the side buttons of walkie-talkies to solve these problems. Utility Model Content
[0003] In view of this, this utility model proposes a waterproof button structure for walkie-talkies that does not require glue. It uses silicone buttons but does not require glue. An internal connector is used to clamp the bottom edge of the silicone button to the stepped hole of the button mounting position, thereby achieving waterproofing.
[0004] The technical solution disclosed in this utility model is a waterproof button structure for a walkie-talkie that does not require glue, including a button mounting hole on the side wall of the walkie-talkie, a silicone button located at the button mounting hole, and a locking device between the silicone button and the button mounting hole to achieve waterproof sealing between the silicone button and the button mounting hole.
[0005] The button mounting holes are stepped holes with a first diameter hole near the outer side and a second diameter hole near the inner side, and the first diameter hole is larger than the second diameter hole. The outer edge of the second diameter hole is provided with a conical hole edge.
[0006] The silicone key includes a keycap portion and a tactile rod portion with an upward protrusion from the center of the inner side of the keycap portion. The keycap portion includes a pressing surface, a first bent sidewall that bends along the edge of the pressing surface toward the same side of the tactile rod portion, and a second bent bottom wall that bends along the lower end of the first bent sidewall toward the tactile rod portion in a vertical direction. The first bent sidewall, the second bent bottom wall and the inner side of the pressing surface form a slot.
[0007] The locking component is a tube with a hollow through hole. The outer wall of the locking component has a front flange and a rear flange at both ends of the hollow through hole. A first conical sidewall is provided between the front face of the front flange and the outer wall. A locking position is formed between the front flange and the rear flange. The tactile rod of the silicone button is inserted into the hollow through hole. The rear flange is locked into the locking groove. The front flange of the locking component is inserted into the second diameter hole. The locking position clamps and connects the second bent bottom wall with the second diameter hole, thereby completing the assembly structure of the silicone button without glue and achieving waterproofing.
[0008] In a preferred embodiment, the side wall of the locking member near the front flange is provided with a plurality of notches that divide the front flange into multiple elastic latching positions.
[0009] In a preferred embodiment, the outer wall of the first bent sidewall of the silicone button is provided with at least one raised ring portion along the periphery of the first bent sidewall, and the raised ring portion is tightly connected to the inner wall of the first aperture hole.
[0010] Furthermore, the cross-section of the convex ring portion is semi-circular.
[0011] In another preferred embodiment, the outer periphery of the bottom of the second bent bottom wall of the silicone button is provided with a flange portion, and a second conical sidewall is provided between the flange portion and the outer edge of the bottom of the second bent bottom wall, and the flange portion is tightly connected to the inner wall of the first aperture hole.
[0012] The beneficial effects of this utility model are as follows: Compared with the existing technology that uses glue to achieve sealing and bonding, this solution uses a locking component to support the silicone button and assemble the silicone button into the button mounting hole, thus avoiding the problems of glue application and glue overflow. The locking component is assembled with the silicone button, and then the front end of the locking component with the assembled silicone button is pressed into the button mounting hole. Since the second diameter hole of the button mounting hole has a conical edge, it cooperates with the first conical sidewall of the front flange of the locking component to achieve a tangential entry. Because the casing of a walkie-talkie is usually made of plastic, which has a certain degree of elasticity, the first conical sidewall and the conical edge of the conical hole are tangentially inserted, and then the front flange is engaged at the bottom of the second diameter hole. The width of the locking position formed by the front and rear flanges of the locking component must be smaller than the natural overlap width of the second bent bottom wall and the second aperture hole of the silicone button. Therefore, when the locking position clamps the second bent bottom wall to the second aperture hole, the second bent bottom wall of the silicone button is clamped and compressed. The elasticity and filling effect of the silicone material achieve a sealed connection between the second bent bottom wall of the silicone button and the upper surface of the second aperture hole of the button mounting hole. This technical solution has a simple structure, is easy to assemble, and helps to ensure waterproof characteristics while reducing the production and processing costs of waterproof buttons for walkie-talkies.

[0020] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this disclosure.
[0021] Please refer to Figure 1 , Figure 2 , Figure 4This technical solution provides a waterproof, glue-free button structure for a walkie-talkie, including button mounting holes on the side wall of the walkie-talkie, silicone buttons located in the button mounting holes, and a locking device between the silicone button and the button mounting holes to achieve a waterproof seal. The button mounting holes are stepped holes with a first diameter 101 near the outer side and a second diameter 102 near the inner side, with the first diameter being larger than the second diameter. The outer edge of the second diameter hole 102 has a tapered edge 1021. The silicone key includes a keycap portion 201 and a tactile rod portion 205 that protrudes upward from the center of the inner side of the keycap portion 201. The keycap portion 201 includes a pressing surface, a first bent sidewall 202 that bends along the edge of the pressing surface toward the same side as the tactile rod portion 205, and a second bent bottom wall 203 that bends along the lower end of the first bent sidewall 202 toward the tactile rod portion 205 in a vertical direction. The first bent sidewall 202 and the second bent bottom wall 203 form a slot 204 with the inner side of the pressing surface. The locking component is a tube with a hollow through hole. The outer wall of the locking component has a front flange 302 and a rear flange 301 at both ends of the hollow through hole. A first conical sidewall 3021 is provided between the front face of the front flange 302 and the outer wall. A locking position 303 is formed between the front flange 302 and the rear flange 301. The tactile rod 205 of the silicone button is inserted into the hollow through hole. The rear flange 301 is inserted into the locking groove 204. The front flange 302 of the locking component is inserted into the second diameter hole 102. The locking position 303 clamps and connects the second bent bottom wall 203 with the second diameter hole 102, thereby completing the silicone button assembly structure solution that is glue-free and waterproof.
[0022] In a preferred embodiment, the sidewall of the locking member near the front flange 302 is provided with a plurality of notches 304 that divide the front flange 302 into multiple elastic locking positions. By designing the notches 304 to divide the front flange 302 and the sidewall of the locking member into multiple elastic locking positions, the notches 304 provide elastic deformation space for the front flange 302 of the locking member to be inserted into the second diameter hole 102 of the button mounting hole, which is more conducive to the assembly of the locking member and the button mounting hole.
[0023] In a preferred embodiment, the outer wall of the first bent sidewall 202 of the silicone button is provided with at least one convex ring portion 2021 along the circumference of the first bent sidewall 202. The convex ring portion 2021 is tightly connected to the inner wall of the first aperture hole 101, and the cross-section of the convex ring portion 2021 is semi-circular. During the assembly of the silicone button, although the second bent bottom wall 203 of the silicone button and the second aperture hole 102 are clamped by the locking position 303 of the locking member to achieve bottom sealing and waterproofing, the tight connection between the convex ring portion 2021 and the inner wall of the first aperture hole 101 achieves an additional layer of waterproofing structure.
[0024] In another preferred embodiment, a flange 2031 is provided on the outer periphery of the bottom of the second bent bottom wall 203 of the silicone button. A second conical sidewall 2032 is provided between the flange 2031 and the outer edge of the bottom of the second bent bottom wall 203. The flange 2031 is tightly connected to the inner wall of the first aperture hole 101. When the second bent bottom wall 203 and the second aperture hole 102 of the silicone button are clamped by the locking position 303 of the locking member to achieve bottom sealing and waterproofing, the designed flange 2031 serves two purposes: firstly, it adds a waterproof structure; secondly, the tight contact of the flange 2031 with the inner wall of the first aperture hole 101 ensures that the inner wall of the second bent bottom wall 203 is tightly abutted against the outer wall of the locking member, which facilitates the more secure locking of the front flange 302 of the locking member into the slot 204.
[0025] This embodiment discloses a waterproof button structure for walkie-talkies that requires no glue. The assembly process involves assembling a locking component with a silicone button, then pressing the front end of the locking component (with the assembled silicone button) into the button mounting hole. Since the second diameter hole 102 of the button mounting hole has a conical edge 1021, it aligns with the first conical sidewall 3021 designed on the front flange 302 of the locking component, allowing for a tangential entry. Because the walkie-talkie casing is typically made of plastic, which has some elasticity, the first conical sidewall 3021 enters tangentially with the conical edge 1021. Then, the front flange 302 engages with the bottom of the second diameter hole 102, achieving a sealed connection between the second bent bottom wall 203 of the silicone button and the upper surface of the second diameter hole 102 of the button mounting hole. This technical solution has a simple structure, is easy to assemble, and helps to ensure waterproof characteristics while reducing the production and processing costs of waterproof buttons for walkie-talkies.
