Abstract

The invention discloses a locking device of a power battery pack. The locking device comprises a power battery pack support and locking parts, lock pins are arranged on the two sides of the power battery pack support, and the power battery pack support is used for fixing the power battery pack; the number of the locking parts are equal to the number of the lock pins; the locking parts are fixed ona vehicle frame body and is used for being matched with the lock pins, and the power battery pack support is detachably arranged on the vehicle frame body; the locking parts comprise locking mechanisms, stopping mechanisms, unlocking mechanisms and side plates; the side plates are fixedly connected with the vehicle frame body through rigid pins, and the locking mechanisms and the stop mechanismsare rotationally connected to the side plates correspondingly; and the unlocking mechanisms are connected with the stop mechanisms correspondingly and can drive the stop mechanisms to rotate. According to the locking device, the relative rotation between the locking mechanisms and the stop mechanisms is controlled to mount and dismount the power battery pack rapidly, so that the power battery packreplacing efficiency of an electric vehicle is remarkably improved.

Description

Technical field [0001] The invention relates to the technical field of new energy special vehicles, and in particular to a power battery pack locking device. Background technique [0002] With the rapid development of new energy technology and the continuous maturity of power battery technology, electric vehicles are becoming more and more popular. New energy vehicles are not only widely used in the field of civilian passenger vehicles, but are also continuously developed and applied in the field of special vehicles. As we all know, power battery technology has always been an important factor restricting the development of new energy vehicles. Especially after power battery technology gradually reaches the market demand indicators, how to replenish power batteries with electric energy has become an important part of market success. [0003] In the field of passenger cars, due to the small battery capacity, power battery charging is generally carried out by charging pile ch...
