Description

Lower plastic part and pole column mounting ventilation structure and battery cover plate Technical Field The utility model relates to the technical field of battery cover plates, in particular to a ventilation structure for mounting a lower plastic part and a pole and a battery cover plate. Background The battery cover plate is an important component part in the battery, and the battery cover plate is covered on the top opening of the shell, and forms a shell cavity for accommodating the battery cell with the shell. The battery cover plate comprises a top cover plate, a lower plastic part is arranged below the top cover plate, a pole is arranged in the top cover plate in a penetrating mode, meanwhile, the pole also penetrates through the lower plastic part, and the pole and the lower plastic part are relatively fixed. In the prior art, the bottom of utmost point post has the connection piece, and the bottom of moulding down is formed with encloses and closes the region, and after the utmost point post passed the top cap piece and moulded down, the connection piece then arranges in enclosing and closes the region, but at the in-process of installing utmost point post, the connection piece inlays the in-process of enclosing and closing the region, encloses the air in closing the region and is compressed, forms great pressure, and pressure reaction is on the connection piece, leads to the connection piece to be difficult to inlay and closes in the region, leads to moulding down and is difficult to install between utmost point post. Disclosure of utility model The utility model aims to provide a ventilation structure for mounting a lower plastic part and a pole, and aims to solve the problem that in the prior art, the lower plastic part and the pole are difficult to mount. The utility model is realized in such a way that the lower plastic part and the polar post are provided with the ventilation structure, the ventilation structure comprises a top cover plate, the lower plastic part and the polar post, the polar post penetrates through the lower plastic part and the top cover plate, a connecting sheet is formed at the bottom of the polar post, a surrounding area is formed at the bottom of the lower plastic part, the connecting sheet is embedded in the surrounding area, a ventilation notch is formed at the periphery of the surrounding area, and the ventilation notch is communicated with the surrounding area. Further, a plurality of ventilation gaps are formed in the periphery of the enclosing area, and the ventilation gaps are arranged at intervals along the periphery of the enclosing area. Further, the bottom of the lower plastic part is convexly provided with an encircling wall which is arranged in an annular mode, the encircling wall surrounds and forms the encircling area, and the ventilation notch is formed in the encircling wall.
