Lower plastic, cover plate structure and battery cell

Abstract

The utility model relates to the technical field of lower plastic, disclose a kind of lower plastic, cover plate structure and electric core, including lower plastic body, exhaust hood and exhaust structure, wherein, pole hole and first liquid injection hole are set on the lower plastic body;The exhaust hood is set on the lower plastic body, and the hollow exhaust space is formed in the exhaust hood interior, and the exhaust space has opposite first side and second side;The exhaust structure includes multiple first elastic sheet and multiple second elastic sheet, and the first elastic sheet and second elastic sheet can be deformed after being stressed;Multiple first elastic sheet is along the first side and is spaced apart, and multiple second elastic sheet is along the second side and is spaced apart, and the first elastic sheet and the second elastic sheet are alternately arranged. Multiple exhaust channels are set, even if the channel is blocked, gas can still be discharged from the first channel gap and the second channel gap by the deformation of the first elastic sheet and the second elastic sheet, to ensure smooth exhaust.
