Detailed Description

The utility model is further described with reference to the following figures and specific examples.

Example one

Referring to fig. 1 to 5, the utility model provides a battery cover plate pole copper-aluminum connection structure, which comprises an aluminum piece 1 and a red copper piece 2, wherein a first protruding block 4 is integrally formed at the bottom of the aluminum piece 1, a second protruding block 5 is integrally formed at the bottom of the first protruding block 4, a groove 3 is formed in the red copper piece 2, the second protruding block 5 is assembled in the groove 3 of the red copper piece 2, and the top of the red copper piece 2 and the bottom of the first protruding block 4 are welded and assembled.

In this embodiment, when needs make aluminium part 1 and red copper spare 2 equipment, make the second bulge piece 5 assemble into the recess 3 department that red copper spare 2 was seted up earlier, weld the seam crossing of aluminium part 1 and red copper spare 2 at last and carry out the secondary and fix, can increase fixed strength like this and reach outer lane aluminium part 1 and red copper spare 2 when fusing, reach former combined material's performance requirement through the mode of back combination, greatly reduced the cost of raw and other materials and processing.

Further, as shown in fig. 1, the second projection 5 is riveted into the recess 3 of the red copper member 2 by an external riveter. In order to ensure that the second convex block 5 can not be pulled out when being assembled into the groove 3 of the red copper piece 2, the second convex block 5 is assembled into the red copper piece 2 more firmly.

Further, as shown in fig. 1, the joint between the top of the red copper member 2 and the bottom of the first protruding block 4 is formed by welding with a laser welding machine, and a weld seam generated by the laser welding machine can enable the connection between the aluminum member 1 and the red copper member 2 to be firmer on one hand, and can enable the second protruding block 5 and the top of the red copper member 2 to be connected without a gap on the other hand.

Further, as shown in fig. 3, the laser welder welds a circle around the joint between the red copper member 2 and the first projection 4. The welding seam surrounds the joint of the first convex block 4 and the red copper piece 2, so that the first convex block 4 and the red copper piece 2 can be welded more fully.
