The invention relates to a quick locking device for connecting a battery box body with a vehicle body, and an electric automobile, the quick locking device comprises a rotating shaft, a spring, a locking body, a rotating body and a fixing body, and the bottom end of the quick locking device is provided with a first cylinder structure and two first grooves; the locking body is provided with two locking shafts extending outwards; the top end of the rotating body is provided with a second cylinder structure and two second grooves; the bottom end of the rotating shaft and the bottom end of the rotating body are both fixed to the fixing body. And the rotating shaft, the spring, the locking body and the rotating body are coaxially arranged. The embodiment of the invention provides the quick locking device for connecting the battery box body with the vehicle body, the quick locking device is simple and reliable in structure and convenient to process, and the locking and unlocking actions canbe realized only by rotating the rotating body in the quick locking device; and the rotating body and the locking body are separated into two independent parts, the strength and the service life of the locking body cannot be affected by frequent use, only the rotating body needs to be replaced after being damaged, and the implementation cost is low.
Description
technical field [0001] The present application relates to the field of a quick locking mechanism between a battery box and a vehicle body, in particular to a quick locking device for connecting a battery box and a vehicle body and an electric vehicle. Background technique [0002] In order to solve the energy problem, my country is vigorously developing the electric vehicle industry. Users’ anxiety about the cruising range has always been a difficult problem to overcome. The use of quick-change technology can meet the customer’s requirements for the cruising range on the one hand, and on the other hand, it can also solve the operating user’s needs. Charging time anxiety. Currently, there are a variety of battery replacement methods. In the related technologies, the connection between the battery box and the vehicle body is realized by bolt tightening or buckle locking. There are defects such as vibration and noise in the buckle-type locking method. [0003] Therefore, it is...
