Description

technical field

[0001] The present invention relates to a battery box and an assembly method thereof, and more particularly to a safe and seamlessly weldable battery box and an assembly method thereof. Background technique

[0002] Electric bicycles play an important role in people's lives, bringing people a fast way of life. Existing electric bicycles generally include a shifting device, a transmission system and a battery. The battery is placed in the battery box. The battery box includes a box body, and some also have a bottom cover that matches the electric vehicle. The left and right box bodies are molded out through the mold, and the battery display is placed on one of them, and then the sealing ring or other sealing parts are placed on the surrounding edges to assemble the other half, and finally fixed by screws or other fasteners. ;During the use of this kind of battery box, due to the perennial wind and rain, the sealing degree between the left box body and the rig...
