Problems solved by technology

However, the operation of the power exchange method also faces some difficulties
First of all, in order to ensure a certain cruising range, the vehicle power battery pack needs to increase the weight of the battery when the capacity density of the existing battery is low, so it is impossible to manually replace the battery, and certain professional equipment is required; Connected by a locking mechanism similar to the opening and closing parts, it is necessary to ensure the accuracy and reliability of positioning and meet the needs of multiple disassembly and assembly
[0005] At present, most of the quick battery replacement methods use battery replacement from the bottom of the car. At present, there are two locking methods for bottom battery replacement: one is to use a linkage locking mechanism, which is easy to operate but prone to failure, easy to get stuck, unable to disassemble and cannot be installed If there is a serious fault, the battery pack will fall; one is to use bolts to lock. This method has a simple structure, but the weight of the battery is borne by the bolts, and the torque is relatively large. In the case of cyclic disassembly of the bolts, the bolts are prone to fatigue damage

Description

technical field [0001] The invention relates to the technical field of battery replacement, in particular to a battery replacement locking device. Background technique [0002] With the development of the economy and the progress of the society, people pay more and more attention to the living environment around them, and their awareness of protecting the environment is getting stronger and stronger. Therefore, the rational use of many environmentally friendly and clean energy is gradually placed on the agenda. As an important tool for people to travel, traditional fuel vehicles have always been concerned about their exhaust emissions. The exhaust emissions cause a lot of pollution. The emergence of pure electric energy vehicles has solved the environmental problems of exhaust emissions from traditional fuel vehicles. Pure electric energy vehicles have the huge advantage of being clean and environmentally friendly with zero emissions, and have been valued by many countries in...
