DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0019] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0020] This embodiment relates to a long-life side button waterproof structure, such as Figure 1-2 As shown, it includes: a button body 100, a waterproof ring 200 and a wear-resistant hard sheet 300.

[0021] Specifically, the key body 100 is installed in the key slot 401 of the device housing 400. The waterproof ring 200 is arranged in the key slot 401 and is located between the inner wall of the key slot 401 and the key body 100. The waterproof ring 200 and the inner wall of the key slot 401 are interference fit to ensure the waterproof sealing performance of the device housing 400 at the key slot 401. The wear-resistant hard sheet 300 is integrally formed with the waterproof ring 200 on the side close to the device switch 500. One end of the wear-resistant hard sheet 300 is close to the touch and pressure surface 510 of the device switch 500, and the other end extends to the side of the key body 100, so that when the key body 100 is pressed, it moves to the side of the touch and pressure surface 510 and squeezes the touch and pressure surface 510 to realize the opening or closing of the device switch 500. It should be noted that the wear-resistant hard sheet 300 is made of hard plastic, and the protruding part on the left end of the wear-resistant hard sheet 300 is a soft plastic part, so as to facilitate in-mold positioning.

[0022] Furthermore, if Figure 1-2 As shown, the waterproof ring 200 includes: a waterproof ring body 210 , a first limiting portion 220 , a second limiting portion 230 , a convex ring 240 and an assembly portion 250 .

[0023] Specifically, the first limiting portion 220 is arranged on the waterproof ring body 210 near the button body 100. The second limiting portion 230 is arranged on the waterproof ring body 210 near the touch and pressure surface 510. The second limiting portion 230 is used to cooperate with the first limiting portion 220 to limit the waterproof ring body 210 in the key slot 401. The convex ring 240 is arranged on the waterproof ring body 210 and is located between the first limiting portion 220 and the second limiting portion 230. The convex ring 240 is used to achieve an interference fit between the waterproof ring body 210 and the inner wall of the key slot 401. The assembly portion 250 is arranged on the waterproof ring body 210 near the second limiting portion 230. The assembly portion 250 extends toward the touch and pressure surface 510 to form a convex portion. The assembly portion 250 is used for assembling the wear-resistant hard sheet 300, and the connection between the assembly portion 250 and the waterproof ring body 210 is the first deformation portion 260.

[0024] Preferably, Figure 1-2 As shown, a groove 201 is further provided on the outer wall of the waterproof ring body 210, and the groove 201 is located between the convex ring 240 and the second limiting portion 230, and the bottom of the groove 201 is the second deformation part 270 of the waterproof ring body 210. This arrangement can not only alleviate the tolerance of the first deformation part 260 during frequent operations, but also the deformation at the same time as the first deformation part 260 can effectively extend the service life of the waterproof ring body 210.

[0025] Furthermore, if Figure 1-2 As shown, the waterproof ring 200 further includes a supporting steel sheet 280. Specifically, the supporting steel sheet 280 is integrally formed and arranged in the waterproof ring body 210 near the button body 100. The supporting steel sheet 280 is used to prevent the sealing from failing when elastic deformation occurs on the side of the waterproof ring body 210 near the contact surface 510.

[0026] Preferably, Figure 1-2 As shown, the assembly portion 250 and the waterproof ring body 210 are surrounded to form a cavity 202 , and a key contact portion 110 is protrudingly provided on one side of the key body 100 close to the wear-resistant hard sheet 300 , and the key contact portion 110 is accommodated in the cavity 202 .

[0027] Preferably, Figure 1-2 As shown, the key slot 401 is a stepped slot, in which two stepped portions 410 are arranged, and the first limit portion 220 is assembled on the stepped portion 410 on the side close to the device switch 500. There is a gap between the head of the key body 100 and the stepped portion 410 on the side of the stepped slot away from the device switch 500, and the gap is the active gap 101 of the key body 100.

[0028] The working principle of this embodiment is as follows: by combining the wear-resistant hard sheet 300 with the waterproof ring 200, not only can the wear resistance of the key at the contact point be solved, but also the combination of the soft glue and the hard sheet can effectively ensure the waterproof function of the key. In addition, a groove 201 is provided on the waterproof ring body 210, so that a second deformation part 270 is formed on the waterproof ring body 210 at the position of the groove 201, which can not only alleviate the tolerance of the first deformation part 260 during frequent operation, but also the deformation at the same time as the first deformation part 260 can effectively extend the service life of the waterproof ring body 210. The high-life side button waterproof structure set in this way has the advantages of good waterproof effect, strong wear resistance and long service life.

[0029] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
