The invention discloses a battery box body locking device and a vehicle body connecting structure of a battery box body. The device comprises a telescopic sleeve, a telescopic pin and an insertable telescopic sleeve which are arranged in the telescopic sleeve, and a fixed sleeve which matches the telescopic pin and is fixed in the telescopic sleeve, a pressing rod which can drive the telescopic pin to axially move into the fixed sleeve is arranged in the telescopic sleeve, a clamping column component capable of keeping the telescopic pin at the position matching the fixed sleeve is arranged inthe telescopic sleeve, and a reset component capable of enabling the telescopic pin to retreat from the fixed sleeve is connected between the telescopic pin and the telescopic sleeve. The locking device is simple and reliable in structure and convenient to machine, the connection operation of the battery box body and the vehicle body is simple, locking and unlocking actions can be achieved only through pressing of the telescopic mechanism, and the requirement for the pressing alignment precision of battery replacing equipment is not high. The quick mounting requirement of the battery box bodyand the vehicle body is met, meanwhile, the reliability of the connecting structure of the battery box body and the vehicle body is guaranteed, the quick change time of the battery box is shortened,and the quick change quality of the battery box is improved.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a locking device for a battery box and a vehicle body connection structure for the battery box. 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. In order to ensure the cruising range, the battery pack needs to be replaced regularly to ensure the battery’s cruising range. To meet customers' requirements for cruising range, on the other hand, it can also solve the charging time anxiety of operating users. There are various battery replacement methods currently appearing, such as the fast replacement method using bolt tightening, which has defects in service life, and the buckle-type locking method has defects such as vibration and noise. In this regard, it is necessary to propose a structural form that is s...
