At present, most batteries in the market adopt a traditional silica gel wire + waterproof groove waterproof structure for waterproofing in consideration of easy assembly, cost and after-sale maintenance factors, the structure can only reach the waterproof grade of IPX5 and below, and particularly, when the section of a battery shell is large, the structure is difficult to reach the waterproof grade of IPX 7. When the structure is subjected to destructive test, the problem of breakage of the root part of the waterproof groove also exists, and the waterproof grade of the whole battery is reduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a novel waterproof construction of electricity friction battery.
The technical scheme of the utility model as follows:
the utility model provides a novel waterproof construction of electricity battery that rubs, includes a section of thick bamboo, battery lower cover and battery package in the aluminum hull, cover under the battery and be equipped with the boss, just the boss all be equipped with all around with battery lower cover integrated into one piece's waterproof circle.
The utility model discloses in, waterproof circle with a section of thick bamboo interference fit in the aluminum hull.
The utility model discloses in, cover under the battery and be equipped with the fixed screw of several, be equipped with the screw on the corresponding position of a section of thick bamboo in the aluminum hull equally, the battery lower cover through mechanical screw fixed mounting in on the section of thick bamboo in the aluminum hull.
The utility model discloses in, the battery package is arranged in inside the section of thick bamboo in the aluminum hull.
The utility model discloses in, the battery lower cover adopts the aluminum alloy to make.
The utility model discloses in, waterproof circle adopts silica gel to make.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses an integrated into one piece's waterproof construction reduces assembly tolerance, adopts the aluminum alloy lower cover simultaneously, further strengthens structural strength to make waterproof circle and aluminum hull middle tube interference fit, play certain shock attenuation and fixed effect when reinforcing waterproof performance, and adopt mechanical screw fixation, convenient assembling reduces the cost of labor between battery lower cover and aluminum hull middle tube.
