Battery pack quick-change device for vehicle and vehicle

Abstract

The invention discloses a battery pack quick-change device for a vehicle and the vehicle, and relates to the technical field of vehicles. The battery pack quick-change device for the vehicle comprises: a limiting pin shaft, wherein one end of the limiting pin shaft is connected with a lower vehicle body of the vehicle; a shell, wherein the shell is connected with the battery pack and is internallyprovided with a cavity with a trapezoidal structure; a bolt, wherein the bolt is positioned at the lower part of the cavity, extends into the cavity and is in threaded connection with the shell; a supporting rod, wherein the supporting rod is positioned in the cavity, is supported in the cavity by a bolt and can move up and down relative to the shell along with the bolt; and a limiting ball, wherein the limiting ball is located in the middle of the supporting rod, a concave part is arranged in the middle of the limiting pin shaft, the interior of the supporting rod is hollow, a notch is formed in the position, corresponding to the concave part, of the supporting rod, the limiting ball is matched with the notch, and when the battery pack quick-changing device is in a locked state, the limiting pin shaft is inserted into the supporting rod, and the limiting ball is clamped into the concave part. The invention further provides a vehicle which comprises the battery pack quick-changing device. The mounting and dismounting efficiency of the battery pack can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a battery pack quick-changing device for a vehicle and the vehicle. Background technique [0002] With the development and progress of society, pure electric vehicles, as an environmentally friendly means of transportation, have the advantages of economical operation, clean and environmental protection, and their application range has become wider and wider. However, due to the limitation of low battery capacity, the mileage is short. At the same time, due to the long charging time of the battery, high battery cost and difficult maintenance, the promotion of pure electric vehicles is limited. In order to extend the mileage of pure electric vehicles, the battery replacement method can be adopted. When the battery power is low, a fully charged battery pack can be quickly replaced at the charging station. The battery replacement time is controlled within 3 minutes, which is the sam...
