[0026] For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Regarding the drawings of the present application, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of the present specification. It should also be understood that the drawings are not drawn to scale.

[0028] A traditional waterproof switch includes a base, a cover, a spring and a button. The base is provided with a first cavity for installing the spring, the cover is provided with a second cavity for the button to slide up and down, a sealing gasket is provided between the base and the cover, and the lower end of the button is pressed against the sealing gasket. However, the thickness of the waterproof switch with this structure is relatively thick, which limits its application in ultra-thin devices.

[0029] Based on the above problems, Figures 1 to 6As shown, the present specification provides an ultra-thin waterproof switch, including a base 1, a cover plate 2, a spring 3 and a button 4, wherein the base 1 is provided with a mounting cavity 100, the spring 3 is arranged in the mounting cavity 100, the cover plate 2 is arranged at the upper end of the base 1, the button 4 includes a pressing portion 40, a sealing pad portion 41 and a pressing portion 42 integrally formed of an elastic material, the cover plate 2 is provided with an opening 200 for the pressing portion 40 to pass through, the sealing pad portion 41 is pressed between the cover plate 2 and the base 1, and the pressing portion 42 extends into the mounting cavity 100 and abuts against the spring 3. In this arrangement, by integrating the traditional button with the sealing pad, the space for installing the sealing pad is saved in terms of height space, and there is no need to set a space for the button to move on the cover plate 2, which not only realizes the lightness and thinness of the switch, but also ensures the waterproof performance and the sensitivity of the operation.

[0030] Specifically, in a traditional waterproof switch, the button moves up and down to trigger the spring, which requires a certain height space, and in particular, a sealing gasket is required to isolate the button from the spring. In this switch, the spring can be triggered only by forming the button, and the button can be formed in the mounting cavity 100 of the base.

[0031] Preferably, the button 4 is made of rubber material or silicone material, and the cover plate 2 is made of metal material, so as to ensure the lightness and thinness of the switch and the strength of the switch.

[0032] In some embodiments, a groove portion 101 adapted to the sealing gasket portion 41 is provided at the upper end of the base 1, and the lower sides of the two side walls of the groove portion 101 are inclined toward the center of the mounting cavity 100. Such a configuration is conducive to the thinness of the switch, and at the same time can guide the accurate positioning of the sealing gasket portion 41, making the assembly process simpler and more efficient. The inclined side walls can help the operator to more easily place the sealing gasket portion 41 into the groove portion 101, thereby reducing errors and time in the assembly process and improving production efficiency.

[0033] Secondly, positioning columns 102 are provided at both ends of the groove portion 101, and a through hole 201 is provided on the cover plate 2. The upper end of the positioning column 102 passes through the through hole 201 and is riveted and fixed. This not only enhances the structural stability and sealing performance of the ultra-thin waterproof switch, but also simplifies the assembly process.

[0034] In some embodiments, positioning holes 410 adapted to the positioning posts 102 are provided on both sides of the sealing pad portion 41 , which can ensure accurate positioning of the sealing pad during the assembly process, thereby forming a more effective sealing effect.

[0035] In some embodiments, an H-shaped positioning groove 103 is provided at the bottom of the base 1, which is mainly used to realize automated production.

[0036] In some embodiments, a sealing convex ring 104 is provided on the upper end surface of the base 1 along the outer edge of the installation cavity 100. Its protruding shape can abut against the sealing pad portion 41 when the cover plate 2 is pressed together, forming a closer contact and increasing the sealing contact area, thereby significantly improving the waterproof and dustproof performance.

[0037] like Figure 5 As shown, in some embodiments, the end surface of the sealing gasket portion 41 facing the installation cavity 100 is provided with a convex ring portion 43 adapted to the installation cavity 100, and the outer wall of the convex ring portion 43 is closely attached to the inner wall of the installation cavity 100, thereby establishing an effective sealing interface, effectively preventing the infiltration of moisture and dust, and improving the overall waterproof and dustproof performance. Secondly, a clear positioning interface is provided, so that the sealing gasket can be more easily aligned and fixed during the assembly process.

[0038] Secondly, a limiting step 44 is provided at the lower end of the convex ring portion 43, and the limiting step 44 contacts the outer edge of the spring 3, providing a clear position limit to prevent the spring from moving too far or losing its normal working position during operation, thereby ensuring that the spring 3 is always within the predetermined working range, thereby improving the stability and reliability of the switch. In addition, the sensitivity of the switch is not affected.

[0039] like Figure 4 As shown, in some embodiments, an I-shaped metal insert 5 is provided in the pressing portion 40, and the metal insert 5 partially extends into the sealing pad portion 41, thereby enhancing the structural strength of the button 4 and ensuring the long-term reliability and durability of the switch.

[0040] In some embodiments, the cross-sectional area of ​​the pressing portion 42 gradually decreases toward the spring 3, and the force applied to the pressing portion 42 will be transmitted to the spring 3 more concentratedly, which can improve the response sensitivity of the spring 3, making the switch more sensitive and responding faster to the pressing operation, thereby improving the user experience.

[0041] like Figure 6 As shown, in some embodiments, the button 4 includes an outer cover 400 and an inner block 401, the hardness of the outer cover 400 is less than that of the inner block 401, the inner layer uses silicone with higher hardness to improve tactile feedback, and the outer layer uses soft silicone to increase comfort and ease of use. This can provide a good touch while avoiding excessive deformation and extending the service life of the button 4.

[0042] Secondly, the pressing portion 42 is arranged at the bottom of the embedded block 401, and at least two arc-shaped cavities 402 are arranged on the embedded block 401 along its axial direction in sequence, so as to form a multi-cavity design, which effectively disperses the pressure applied to the button 4. At the same time, each arc-shaped cavity 402 can independently respond to the change of force, thereby ensuring that the force is transmitted more evenly when pressing, reducing local stress concentration, and reducing material fatigue and wear.

[0043] Preferably, the upper end of the arc-shaped cavity 402 is a circular plane, and the lower end thereof is a spherical surface, so that the pressing force can be concentrated along the axis direction of the embedded block 401 to avoid misalignment of the contact points between the spring and the contact sheet when they are in conductive contact.

[0044] Preferably, three arc-shaped cavities 402 are arranged in sequence, the circular planes have the same size, and the heights of the spherical surfaces decrease in sequence, so that graded feedback is generated during the pressing of the button 4, allowing the user to feel a sense of hierarchy and progression.

[0045] An elliptical cavity 403 is provided at the lower portion of the embedded block 401 to further enhance the tactile feedback of the button and reduce the noise when the switch is used.
