Abstract

The invention provides a power battery cover plate and a power battery using the same. The power battery cover plate comprises a cover plate base body with a pole column unit, wherein the pole column unit comprises a pole column base and a pole column body; the pole column base is in sealing and blocking fit with the lower side surface of the cover plate base body by a center sealing ring; the pole column body is arranged on the pole column base; the pole column body is provided with a penetrating section which can penetrate out of a pole column hole in the upper edge of the cover plate base body and extend in the up-down direction; the outer periphery surface of the penetrating section is provided with a blocking slot extending or distributed around the pole column body; a lifting piece which is in blocking fit with the upper side surface of the cover plate base body is arranged outside the penetrating section in a sleeving manner; elastic inverted pokes are arranged on the lifting piece, and the elastic inverted pokes extend along the radial direction of the pole column body, and upwards turnover to be inserted into the blocking slot so as to lift upwards the pole column unit. According to the power battery cover plate and the power battery using the same, the assembling process is fast, easy and convenient, the lifting piece is simple in manufacture technique, and the whole design and manufacture cost is relatively reduced.

Description

technical field [0001] The invention relates to a power battery cover plate and a power battery using the cover plate. Background technique [0002] The technology of pure electric vehicles is becoming more and more mature, and the technology of hybrid electric vehicles is becoming more and more perfect. The power battery is the main energy carrier and power source of various electric vehicles, and it is also the main component of the whole electric vehicle. [0003] The existing power battery cover usually consists of a cover base, a safety valve structure, and positive and negative pole units. The pole hole is used to realize the conductive connection with the outside world, and a sealing ring is arranged in the pole body and the pole hole to realize the sealing of the pole body, such as a lithium battery disclosed in the Chinese utility model patent with the authorized announcement number CN201523031U Combined cover plate, the cover plate includes a cover plate base ...
