Description

TECHNICAL FIELD

[0001] The utility model relates to the field of traffic tool accessories, especially to a battery mounting structure mainly used for electric bicycle. BACKGROUND

[0002] The battery of the conventional electric bicycle adopts the mounting structure of taking from above, which leads to the inconvenience of battery mounting and dismounting in the case of insufficient space above, such as being blocked by a crossbar. The battery of the side-drawing type is generally installed in an exposed manner, which has poor waterproof and theftproof performance. The battery mounted in the concealed manner is invisible from outside and has good waterproof and theftproof performance, but the lower tube and the five-way pipe of the frame must be staggered to draw out the battery due to the need to set a lower-drawing space for the battery, and a section of the bottom frame is generally welded at the bottom end of the lower tube to set the five-way pipe, which has a complex structure and a complicated process and affects the appearance of the whole vehicle. Moreover, the battery is above and the controller is below, and the controller must be dismounted before the battery is drawn out during battery maintenance, which causes inconvenience to maintenance and repair. Therefore, the applicant proposes a Chinese utility model patent application with the title of "Concealed Lower-drawing Battery Mounting Structure", which bends the lower end of the lower tube into a curved section to form a five-way pipe, so that the lower end of the lower tube is staggered with the main body of the lower tube to facilitate the mounting and taking of the battery, the manufacturing process is simpler, and the appearance is more beautiful. Meanwhile, the controller is arranged inside the bottom cover, and the controller will be away from the battery after the bottom cover is opened, so that the battery can be directly taken out without dismounting the controller, and the maintenance and repair operation is more convenient. However, this scheme still has some problems, such as the use of elastic lock (lock core) to fix the battery, which not only has high cost but also needs to be equipped with a key, and only the key can be used to open it, which is troublesome to use. In addition, the brake wire and the control wire are routed from the outside of the lower tube, which is not only not beautiful but also not safe and easy to damage. In addition, the heat generated by the controller in the bottom cover is not easy to dissipate. UTILITY MODEL CONTENTS
