[ detailed description ] embodiments

The first embodiment is as follows:

referring to fig. 1 to 4, a battery module sheet metal box 100 with high waterproof performance in this embodiment includes a box 1 and a box cover 2, where the box 1 is of an integral sheet metal structure and has an opening 11 formed at an upper portion thereof, and the box cover 2 covers the opening 11.

A step surface 21 is formed by horizontally contracting below the peripheral edge of the box cover 2, a turnover plate surface 22 is arranged by downwards extending the edge of the step surface 21, and the outline formed by the peripheral surface of the turnover plate surface 22 is matched with the opening 11 and extends into the box body 1. A plurality of horizontal connecting columns 23 which are distributed horizontally and inwards are arranged on the turnover plate surface 22 at intervals around the opening 11 for one circle, one end of each horizontal connecting column 23 is closed, a threaded hole 24 is formed in the surface of the other end of each horizontal connecting column 23, and the threaded holes 24 penetrate through the outer side surface of the turnover plate surface 22.

The upper part of the box body 1 is provided with through holes 12 which are in one-to-one correspondence with the threaded holes 24, and the box body 1 and the box cover 2 are connected together by screws 3 which pass through the through holes 12 and then are screwed into the threaded holes 24.
