Problems solved by technology

[0003] The purpose of the present invention is to provide an easy-to-implement solution to overcome the problem of using electronic products such as mobile phones in rainy days and when there is a lot of sweat because too much water (or sweat) from the battery cover (back cover) causes corrosion of the components on the PCB. failure

Embodiment Construction

[0013] A specific embodiment of the present invention is as figure 1 As shown, it is a mobile phone battery cover waterproof structure, which includes a battery cover 2, a middle case 3 and a PCB board 4 from the outside to the inside. A water-blocking groove 1 is provided in the matching area of ​​the inner surface. There may be multiple water blocking grooves. The water blocking groove is 0.2-0.3mm deep and 1-3mm wide.

[0014] The middle shell of the mobile phone matches the inner surface of the battery cover, and the gap is uniform (for example, 0.1mm). Water will easily penetrate due to capillary phenomenon. Add an appropriate water-blocking groove on the matching area between the middle shell of the mobile phone and the inner surface of the battery cover to change In the case of a uniform 0.1mm gap between the inner surface of the battery cover and the mating surface of the middle case, the 0.1mm gap will be suddenly enlarged on the water inlet path, and the capillary ...

Abstract

The invention provides a waterproof structure for a battery cover. The waterproof structure for the battery cover sequentially comprises the battery cover, a middle shell and a PCB (printed circuit board) from the outside in, wherein the middle shell is matched with the inner surface of the battery cover; and a water blocking slot is formed in an area on the middle shell and matched with the inner surface of the battery cover. The purpose of avoiding invalidation of functions of a mobile phone due to too much water (or sweat) entering from the battery cover (a back cover) when electronic products such as the mobile phone are used on rainy days or too much sweat is generated can be fulfilled; and the waterproof structure for the battery cover is easy to assemble and is reliable.

Description

technical field [0001] The invention relates to a waterproof structure of a battery cover. Background technique [0002] When electronic products such as mobile phones are used in rainy days and when there is a lot of sweat, water (or sweat) will enter from the battery cover (back cover), which will cause the components on the mobile phone PCB to be corroded and cause functional failure. The existing technology mainly solves the above problems by improving the tightness of assembly. For example, Chinese patent applications with application numbers 02207861.4, 201020693051.4 and 201120070291.3 all involve communication terminals with waterproof functions, which are mainly realized by snapping tight waterproof casings. This solution is operationally difficult and not as easy to implement as it was supposed to be. Contents of the invention [0003] The purpose of the present invention is to provide an easy-to-implement solution, which can overcome the problems of using elect...
