Abstract

The invention relates to the technical field of battery accessories, in particular to an integrated water-cooling extrusion large-bottom-plate battery box. The integrated water-cooling extrusion large-bottom-plate battery box comprises a large-bottom-plate welding assembly, a water-cooling plug assembly and a whole vehicle mounting bracket, wherein the large-bottom-plate welding assembly comprises first extrusion parts, a second extrusion part and a water cooling runner; the first extrusion parts and the second extrusion part are each of a plate-shaped structure with the hollow interior, the number of the second extrusion part is at least one, the first extrusion parts are welded to the two sides of the second extrusion part side by side, and the first extrusion parts and the second extrusion part jointly form a plate-shaped overall structure; the water-cooling flow channel is arranged at the hollow inner cavities of the first extrusion part and the second extrusion part along the length directions of the first extrusion part and the second extrusion part, and the two ends of the water-cooling flow channel are blocked by water-cooling plug assemblies; and the whole vehicle mounting bracket is mounted on the end face of the large-bottom-plate welding assembly. According to the scheme, good ball strike resistance and a water cooling structure are achieved, safety is good, and integration on a whole vehicle is facilitated.

Description

technical field

[0001] The invention relates to the technical field of battery accessories, in particular to an integrated water-cooled extruded large-bottom battery box. Background technique

[0002] With the vigorous development of new energy vehicles, the competition is becoming more and more fierce. Every OEM has begun to build its own platform models. How to make their own platforms more attractive must have considerable novelty and innovation. In addition, new energy vehicles spontaneously ignite or catch fire and explode after being hit hard, so the battery pack itself must have sufficient protection for the battery cells, and the bottom ball is the point that needs the most attention.

[0003] Existing battery boxes or battery boxes have the following problems:

[0004] 1. The number and types of parts are many, the welding process is complicated, and the cost is high.

[0005] 2. The anti-bottom ball performance is weak, and it is mainly realized by using thicker ...
