The application relates to a quick locking device for connecting the battery box and the vehicle body and an electric vehicle. The quick locking device includes a rotating shaft, a spring, a locking body, a rotating body and a fixed body, and the bottom end has a first cylinder structure and is provided with two first grooves; the locking body has two locking shafts extending outward; the top of the rotating body has a second cylindrical structure and is provided with two second grooves; the rotating shaft and the bottom of the rotating body Both ends are fixed on the fixed body; the rotating shaft, the spring, the locking body and the rotating body are coaxially arranged. The embodiment of the present application provides a fast locking mechanism for connecting the battery box and the vehicle body. The body and the locking body are separated into two separate parts. Frequent use will not affect the strength and life of the locking body. After the rotating body is damaged, only the part needs to be replaced, and the cost is low.
Description
technical field [0001] The present application relates to the field of quick locking mechanisms for battery boxes and vehicle bodies, and 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, and users' anxiety about the cruising range has always been a difficult problem to overcome. Charge time anxiety. There are a variety of power exchange methods that have appeared at present. In the related art, the method of tightening the bolts or locking when the buckle is used is used to realize the connection between the battery box and the vehicle body. The snap-on locking method has defects such as vibration and noise. [0003] Therefore, it is necessary to propose a structure that is simple in structure, convenient and reliable, and low in cost. SUMMARY OF THE INVENTION [0004] The e...
