Abstract

The invention discloses a battery box, which comprises a box body, a lower case installed at the bottom of the box body, a bottom cover covered on the lower case, an upper case installed on the top of the battery box and a top cover covered on the upper case; The box body is an integrally formed ring-shaped cylinder; the upper end surface of the inner wall of the box extends downward to the lower end surface, and a number of supporting ribs are provided, and interval grooves are formed between the supporting ribs; the bonding between the lower shell and the box body A number of bumps A extend upwards, and a ring-shaped groove is provided on the outer edge of the bumps A on the bonding surface, and the bumps A match the interval grooves; the bonding between the upper shell and the box body A plurality of bumps B extend downwards, and an annular groove is provided on the outer edge of the bumps B on the bonding surface, and the bumps B are matched with the interval grooves. The invention has good water leakage prevention effect on the batteries in the battery box, and is convenient to take and place. The invention also discloses an assembly method of the battery box.

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...
