Battery case of electric bicycle

Abstract

The invention relates to a battery case of an electric bicycle; key points of the battery case are as follows: the battery case comprises a case body, a case cover, a handle and a locking device, wherein the case body, the case cover and the handle are injected and molded to form an integral body. The case body comprises a baseplate, a side frame part of the case body, a main beam blocking shell and a case cover fixing column. An inserting and limiting part is arranged at the front side of the case body. The case cover comprises a cover plate part, a supporting part, a bolt column and a handle base part. The supporting part is arranged at the front part of the case cover. The handle base part is arranged at the back of the cover plate part. The handle is rotatably connected on the handle base part of the case cover. The case cover is detachably fixed on the case body. The locking device comprises a lock which is fixedly arranged at the back of the case cover; and a spring bolt of the lock can be used for locking the battery case of the electric bicycle on the corresponding electric bicycle. When being arranged or dismantled, the battery case of the electric bicycle of the invention rotatably moves by using the supporting part as a supporting point, thereby more labor is saved and the dismantling and installation are convenient.

Description

technical field [0001] The invention relates to a battery box equipped with a rechargeable battery, in particular to a battery box for an electric bicycle. Background technique [0002] An electric bicycle is a special bicycle that uses a battery as an auxiliary energy source, has two wheels, and can realize the functions of manpower riding, electric or electric assist. Although it has the appearance characteristics of ordinary bicycles (some have the appearance characteristics of motorcycles), the main thing is that it is equipped with operating components such as motors, controllers, batteries, display instrument systems and handles on the basis of ordinary bicycles. Mechatronic personal transportation. As a means of transportation, electric bicycles have developed rapidly in just a few years. In order to solve the problem of anti-theft and charging, it is often necessary to unload the battery of the electric bicycle parked outside from the electric bicycle and take it h...

AI Technical Summary

Problems solved by technology

It can be seen from this that: firstly, the structure is relatively complicated, and the seat needs to be adjusted when disassembling the battery box 32, which greatly increases the difficulty and cost of the seat structure.

Secondly, due to the high installation position of the battery box of this oblique battery box structure, the center of gravity of the whole vehicle is high, which reduces the stability and safety of the electric bicycle.

Again, because in the process of disassembling the battery box, the stroke of the battery box in the up and down direction is relatively large, and usually the weight of the battery box after being filled with rechargeable batteries is all relatively large, so it is relatively laborious for the rider to operate. Especially for some weaker cyclists (such as female cyclists or older cyclists) it is more difficult
