Abstract

The invention discloses a battery case. The battery case comprises a case body, a lower shell arranged on the bottom of the case body, a bottom cover arranged on the lower shell, an upper cover arranged on the top of the battery case, and a top cover arranged on the upper cover; the case body is an integrated annular cylinder; a plurality of supporting protruded strips are arranged between the upper end surface and the lower end surface of the internal wall of the case body, separation grooves are formed between the support protruded strips; a plurality of embossments A stretch upwards from the joint surface between the lower shell and the case body, a ring of annular groove is arranged on the joint surface along the outer edges of the embossments A, the embossments A are matched with the separation grooves; a plurality of embossments B stretch downwards from the joint surface between the upper cover and the case body, a ring of annular groove is arranged on the joint surface along the outer edges of the embossments B, and the embossments B are matched with the separation grooves. The battery case can well protect the battery in the case from water, and the battery can be conveniently stored in the case and taken out from the case. The invention also discloses an assembly method of the battery case.

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...
