Battery pack quick change locking device and vehicle

Abstract

The invention provides a battery pack quick-change locking device and a vehicle, and belongs to the field of vehicles. The battery pack quick-change locking device comprises a plurality of fixing rods, an installation seat, and a locking block, wherein the multiple fixing rods are fixedly arranged on the side wall of a battery pack; the installation seat is fixed to a vehicle body, and provided with a plurality of first gaps extending in the vertical direction and with the lower parts communicating with the outside world; and the locking block is arranged on the installation seat and can moverelative to the installation seat in the horizontal direction, the locking block is provided with second gaps corresponding to the first gaps one to one, the second gaps are provided with transverse parts extending in the horizontal direction and longitudinal parts communicating with the transverse parts and extending in the vertical direction, and the lower ends of the longitudinal parts communicate with the outside world; and movement of the locking block makes the battery pack quick-change locking device have the locking state where the first gaps are overlapped with the transverse parts and the fixing rods extend into the overlapped position, and the opening state where the first gaps are overlapped with the longitudinal parts and the fixed rods can move downwards along the first gaps.According to the battery pack quick-change locking device and the vehicle, the overall structure can be simplified and the volume is decreased.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a battery pack quick-change locking device and a vehicle. Background technique [0002] The key to realize quick change of electric vehicle battery pack is how to design the quick change device, and the key to the design of the quick change device is the design of the locking mechanism. The locking mechanism ensures that when the battery pack is replaced to the whole vehicle, it can be unlocked smoothly; when the battery pack is installed in place, the locking mechanism can be quickly locked, thus ensuring the reliability of quick battery pack replacement. [0003] The existing locking mechanisms are all independent structures, and each locking mechanism is independent of each other and does not interfere with each other. As a result, the overall structure of the quick change device is complicated, the cost is high, and the volume is large, which occupies the design space of the power bat...

Problems solved by technology

[0003] The existing locking mechanisms are all independent structures, and each locking mechanism is independent of each other and does not interfere with each other. As a result, the overall structure of the quick change device is complicated, the cost is high, and the volume is large, which occupies the design space of the power battery pack, resulting in The size of the power battery pack is reduced, which in turn affects the driving range of the entire electric vehicle
