Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment as necessary without making a contribution thereto after reading the present specification, but all are protected by patent laws within the scope of the claims of the present invention.

The embodiment relates to a waterproof structure of a long-life side key, as shown in fig. 1-2, comprising: the key comprises a key body 100, a waterproof ring 200 and a wear-resistant hard sheet 300.

Specifically, the key body 100 is mounted in the key groove 401 of the device case 400. The waterproof ring 200 is disposed in the key slot 401 and located between the key body 100 and the inner wall of the key slot 401. The waterproof ring 200 is in interference fit with the inner wall of the key groove 401 to ensure the waterproof sealing performance of the device shell 400 at the key groove 401. The wear-resistant hard sheet 300 and the waterproof ring 200 are integrally formed on one side close to the device switch 500. One end of the wear-resistant hard sheet 300 is close to the touch surface 510 of the device switch 500, and the other end extends towards one side of the key body 100, so that when the key body 100 is pressed, the wear-resistant hard sheet moves towards one side of the touch surface 510 and presses the touch surface 510, and the device switch 500 is turned on or turned off. It should be noted that the hard wear-resistant sheet 300 is made of hard plastic, and the protruding part at the left end of the hard wear-resistant sheet 300 is a soft rubber part, so that the positioning in the mold is facilitated.

Further, as shown in fig. 1-2, the waterproof ring 200 includes: the waterproof ring comprises a waterproof ring body 210, a first limit part 220, a second limit part 230, a convex ring 240 and an assembling part 250.

Specifically, the first position-limiting portion 220 is disposed on the waterproof ring body 210 near the key body 100. The second limiting portion 230 is disposed on the waterproof ring body 210 near the pressing surface 510. The second position-limiting portion 230 is used to cooperate with the first position-limiting portion 220 to limit the waterproof ring body 210 in the key slot 401. The protruding ring 240 is disposed on the waterproof ring body 210 and located between the first position-limiting portion 220 and the second position-limiting portion 230. The convex ring 240 is used for realizing interference fit between the waterproof ring body 210 and the inner wall of the key groove 401. The assembling portion 250 is disposed on the waterproof ring body 210 near the second position-limiting portion 230. The fitting portion 250 extends toward the pressing surface 510 to form a protrusion. The assembling portion 250 is used for assembling the hard wear-resistant sheet 300, and the joint of the assembling portion 250 and the waterproof ring body 210 is a first deformation portion 260.

Preferably, as shown in fig. 1-2, a groove 201 is further disposed on an outer side wall of the flashing ring body 210, the groove 201 is located between the protruding ring 240 and the second position-limiting portion 230, and a bottom of the groove 201 is a second deformation portion 270 of the flashing ring body 210. Set up like this and not only can alleviate the tolerance of first deformation position 260 in frequent operation process, take place deformation simultaneously with first deformation position 260 moreover and can effectively prolong the life of waterproof circle body 210.

Further, as shown in fig. 1-2, the waterproof ring 200 further includes a support steel sheet 280. Specifically, the supporting steel sheet 280 is integrally formed in the waterproof ring body 210 at a side close to the key body 100. The supporting steel sheet 280 is used for preventing the sealing failure when the elastic deformation is generated on one side of the waterproof ring body 210 close to the contact surface 510.

Preferably, as shown in fig. 1-2, the assembly portion 250 and the waterproof ring body 210 enclose to form a cavity 202, a key pressing portion 110 is convexly disposed on one side of the key body 100 close to the hard wear-resistant sheet 300, and the key pressing portion 110 is accommodated in the cavity 202.

Preferably, as shown in fig. 1-2, the key slot 401 is a stepped slot in which two stepped portions 410 are disposed, and the first stopper 220 is fitted on the stepped portion 410 at a side close to the device switch 500. A gap is formed between the head of the key body 100 and the step portion 410 of the stepped groove on the side far from the device switch 500, and the gap is the movable gap 101 of the key body 100.

The working principle of the present embodiment is roughly as follows: through the mutually combined wear-resistant hard sheet 300 and the waterproof ring 200, the wear resistance of the key at the contact point can be solved, and the mutually combined soft rubber and the hard sheet can effectively ensure the waterproof function of the key. In addition, the groove 201 is formed in the waterproof ring body 210, so that the second deformation part 270 is formed in the position, located in the groove 201, of the waterproof ring body 210, tolerance of the first deformation part 260 in a frequent operation process can be relieved, and the service life of the waterproof ring body 210 can be effectively prolonged by deformation of the first deformation part 260. The high life side button waterproof construction who sets up like this has that water-proof effects is good, and the wearability is strong, long service life's advantage.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered by the claims of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
