Abstract

The utility model discloses a waterproof housing structure for an electronic product, and the structure comprises an upper housing and a lower housing. A circle of silica-gel groove is disposed along the periphery of one housing inside the housing in an all-in-one manner. A silica gel sealing ring is molded as a body inside the silica-gel groove. A sealing groove is disposed on the silica gel sealing ring along the extension direction of the silica gel sealing ring. An embedded flange is disposed on the lower surface of the other housing and is corresponding to the sealing groove. After the upper housing and the lower housing are closed, the embedded flange is tightly embedded into the sealing groove. Therefore, the difficulty in assembly of a waterproof electronic product is reduced and the efficiency of production is improved through the all-in-one common-mode combination of the silica gel sealing ring with the lower housing. Meanwhile, the waterproof structure is different from a sealing waterproof mode of conventional ORING silica gel, overcomes the great shrinkage variability of the characteristics of conventional waterproof strip materials, enables water not to penetrate into the interior of the electronic product when the product is under a certain water pressure, and improves the waterproof performance of the electronic product.

For achieving the above object, the utility model adopts following technical scheme:

An electronic product casing waterproof construction, comprises upper and lower two housings, and in being wherein wholely set a circle silica gel groove along its periphery in a housing, one-body molded in this silica gel groove have a silica gel sealing ring, on silica gel sealing ring, along its bearing of trend, is provided with seal groove; In the corresponding above-mentioned seal groove of another housing lower surface, be provided with embedding flange, after upper and lower two housings closes, embed in the tight embedding sealing groove of flange.

As a kind of preferred version: described silica gel groove is arranged on lower house, and described embedding flange is arranged on upper shell.

As a kind of preferred version: be provided with a circle enchasing plate along surrounding on described upper shell lower surface, above-mentioned embedding flange is integrally formed at this enchasing plate lower end.

As a kind of preferred version: the sidewall of described lower house surrounds one for installing the chimeric cavity of housing, and above-mentioned seal groove is arranged in this chimeric cavity, and after upper shell closes on lower house, the enchasing plate outer wall of upper shell and the inside sidewalls of lower house are close to.

As a kind of preferred version: described silica gel sealing ring is liquid-state silicon gel.

As a kind of preferred version: described seal groove is arc, the corresponding seal groove of described embedding flange is also arc.

As a kind of preferred version: be provided with a square through hole on the roof of described upper shell, be covered with a display screen on this square through hole.

As a kind of preferred version: described square through hole periphery is provided with embedding step, and above-mentioned display screen is installed on this embedding step.

The utility model compared with prior art has obvious advantage and beneficial effect, particularly, as shown from the above technical solution, by silica gel sealing ring is combined with lower house one common mode, reduced the assembling difficulty of waterproof electronic product, improved production efficiency, simultaneously, this waterproof construction is different from the water-tight mode of traditional ORING silica gel, overcome the very big variability of contraction of conventional waterproof strip material characteristic, make product under certain hydraulic pressure, water cannot infiltrate electronic product inside, has improved the waterproof ability of electronic product.

For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, be described in detail.
