[ detailed description ] embodiments

Referring to fig. 1-3, the present invention provides a waterproof sealing ring 1, which is made of elastic material and assembled between a front shell 20 and a rear cover 21 of an electronic device 2, wherein the front shell 20 can be fastened and fixed on the rear cover 21, and the waterproof sealing ring 1 includes an embedded body 10 and a waterproof body 11.

The main body 10 can be inserted into an annular groove formed on an end surface of one of the front housing 20 and the rear cover 21, in this embodiment, the annular groove 200 is formed on the front housing 20, the cross section of the main body 10 corresponds to the cross section of the annular groove 200 and is substantially triangular, and the bottom of the main body 10 abuts against the bottom of the annular groove 200.

The waterproof body 11 includes a first waterproof layer 110 and a second waterproof layer 111 extending from the embedded body 10 to a direction away from the bottom of the annular groove 200 to form different heights, wherein the second waterproof layer 111 is located inside the first waterproof layer 110, that is, the second waterproof layer 111 is closer to the inside of the electronic device 2 than the first waterproof layer, the second waterproof layer 111 is higher than the first waterproof layer 110, that is, the extending length of the second waterproof layer 111 extending to the direction away from the bottom of the annular groove 200 is greater than the extending length of the first waterproof layer 110 extending to the direction away from the bottom of the annular groove 200, when the rear cover 21 is fastened and fixed to the front cover 20, the annular boss of the front cover 20 or the rear cover 21 on the end surface corresponding to the annular groove will abut against the space between the first waterproof layer 110 and the second waterproof layer 111, and when the rear cover 21 is fastened and fixed with respect to the front cover 20, a part of the structure of the front cover 20 without an annular groove or the annular boss of the rear cover 21 on the end surface corresponding to the annular groove is clamped into the annular groove, in this embodiment, the annular boss 210 is disposed on the rear cover 21, the first waterproof layer 110 and the second waterproof layer 111 are extruded and deformed in the process of clamping the annular boss between the first waterproof layer 110 and the second waterproof layer 111, so that the waterproof seal ring 1 connects the front cover 20 and the rear cover 21 without a gap, thereby playing a waterproof role, the first waterproof layer 110 abuts against the inner wall of the annular groove 200 and is higher than the annular groove 200, forming a waterproof first waterproof wall, preventing foreign matters or liquid from invading the inner side of the electronic device from the outer side of the electronic device 2, the second waterproof layer 111 abuts against the inner wall of the annular groove 200 close to the inner side of the electronic device 2 and is higher than the annular groove 200, and forming a waterproof second waterproof wall which is higher than the first waterproof wall.

In this embodiment, a substantially V-shaped waterproof groove 112 is formed between the first waterproof layer 110 and the second waterproof layer 111, and when the annular protrusion 210 is inserted into the annular groove 200 between the first waterproof layer 110 and the second waterproof layer 111, the waterproof groove 112 between the first waterproof layer 110 and the second waterproof layer 111 is located below the annular protrusion 210, so that if a foreign substance or liquid is inadvertently infiltrated into the first waterproof layer 110, the foreign substance or liquid will be confined in the waterproof groove 112 and blocked by the second waterproof layer 110, and thus cannot enter the inside of the electronic device 2.

When the waterproof sealing ring is installed, the embedded body 11 is first embedded into the annular groove 200, the embedded body 11 abuts against the annular groove 200, for example, the bottom of the embedded body 11 abuts against the bottom of the annular groove 200, for example, the embedded body 11 and the annular groove 200 are mutually matched by the same shapes of the two, then, the rear cover 21 is covered on the front shell 20, the annular boss 210 of the rear cover 21 is correspondingly accommodated between the first waterproof layer 110 and the second waterproof layer 111 of the waterproof body 11 of the annular groove 200 of the front shell 20, the rear cover 21 is fastened and fixed on the front shell 20, the annular boss 210 of the rear cover 21 extrudes the waterproof body 11 to deform and tightly clamp between the first waterproof layer 110 and the second waterproof layer 111, so that the front shell 20 and the rear cover 21 are seamlessly connected by the waterproof sealing ring 1.

To sum up, the waterproof sealing ring 1 of the present invention is provided with two first waterproof layers 110 and two second waterproof layers 111 with different heights, wherein the second waterproof layer 111 near the inside of the electronic device 2 is higher than the first waterproof layer 110, when the front shell 20 is fastened and fixed on the rear cover 21, the annular boss 210 of the rear cover 21 is inserted into the annular groove 200, the first waterproof layer 110 and the second waterproof layer 111 are respectively located at two sides of the boss 210, and the boss 210 is respectively abutted against the inner sides of the first waterproof layer 110 and the second waterproof layer 111, that is, the boss 210 is respectively abutted against one side of the first waterproof layer 110 and the second waterproof layer 111 facing the waterproof groove 112, so as to form two waterproof walls, as shown in fig. 4, if the gap between the front shell 20 and the rear cover 21 is too large due to improper force application by a user, so that the first waterproof layer 110 is not sealed with one of the front shell 20 or the rear cover 21, if foreign matters or liquid inadvertently intrude from the first waterproof layer 110, the second waterproof layer 111 is higher than the first waterproof layer 110, so that the second waterproof layer 111 can prevent foreign matters or liquid from entering the electronic device 2.
