Waterproof structure and electronic device with same

Abstract

The invention relates to a waterproof structure which comprises a shell and a cover, wherein the cover is assembled on the shell. The shell is provided with a groove. The cover comprises a protruding rib and a soft material structure, wherein the protruding rib is coated with the soft material structure, and the protruding rib and the soft material structure are integrally formed. The soft material structure is in interference fit with the groove. Due to the arrangement of the protruding rib, when the soft material structure is in interference fit with the groove, a support of the protruding rib can make the deformation of the soft material be reliable and achieve a good waterproof effect. Meanwhile, due to the fact that the soft material structure and the cover are integrally formed, additional assembly waterproof soft rubber is not needed, the assembly deviation of the waterproof soft rubber does not need to be taken into consideration for the arrangement of magnitude of interference, and therefore the good waterproof effect is achieved through a small amount of interference, and the requirement for the structure strength of a battery cover is lowered. The invention further relates to an electronic device with the waterproof structure, for example, a mobile phone. The waterproof structure has the good waterproof effect, assembly processes are reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to a waterproof structure and an electronic device using the waterproof structure. Background technique [0002] In recent years, with the increase of people's outdoor activities, various waterproof electronic devices emerge in an endless stream. In the waterproof link of such electronic devices, the waterproofing of the battery cover is always a technical difficulty. In the prior art, the waterproofing of the battery cover mostly adopts the side pressure waterproofing method, please refer to figure 1 and figure 2 The waterproof structure of the electronic device includes a rear case 100, a soft battery cover 200 and a battery cover 300, the rear case 100 includes a plane 101 and a side 102 perpendicular to the plane, the plane 101 and The sides 102 are connected in an "L" shape, and the battery cover 300 includes a plane 301 and a side 302 perpendicular to the plane 301, the plane 301 and the side 302 are connected in an upsi...

AI Technical Summary

Problems solved by technology

In the above-mentioned waterproof structure, the battery cover waterproof soft glue 200 is processed and manufactured separately. When the battery cover waterproof soft glue 200 is fixed on the battery cover 300, a special assembly station is required. At the same time, the operation consistency of the pasted and fixed assembly process is poor , there is a large assembly deviation, and it is difficult to ensure that the assembly is in place, please refer to image 3 , A is the distance between 102 planes on the side of the rear case, B is the distance between 302 planes on the side of the battery cover, the manufacturing accuracy of A and B directly affects the interference and waterproof of the battery cover soft rubber 200, and because the dimensions of A and B are large, The tolerance is difficult to control, thus increasing the manufacturing difficulty of the battery cover 300 and the casing 100. At the same time, for the battery cover soft rubber 200, its own manufacturing tolerance plus assembly deviation leads to inconsistent interference fit deformation everywhere. To achieve a reliable waterproof effect, it is necessary to increase the interference. A larger interference has higher requirements on the structural strength of the rear case 100 and the battery cover 300. Therefore, it is necessary to increase the strength design in the structure, which will inevitably affect the rear case. The overall design dimensions of the shell 100 and the battery cover 300; in addition, the waterproof effect of the side pressure interference waterproof method in the prior art depends entirely on the pressing force of the two planes 102, 302 on the battery cover soft glue 200, in the same Under the action of pressing force, according to the above analysis, the interference fit deformation of the soft battery cover 200 is inconsistent, so the waterproof effect is poor. In addition, because the rear case 100, a soft battery cover 200 and a battery cover 300 are manufactured When reassembling, it is necessary to consider the sealing of the two waterproof positions of the rear case 100 and the battery cover soft rubber 200, and the battery cover soft rubber 200 and the battery cover 300, which increases the difficulty of waterproofing
