In the present invention, the mounting chamber is opened laterally, and the battery assembly is loaded into or unloaded from the side of the mounting chamber. When the storage battery assembly is installed, the storage battery assembly is placed on a fork arm of a small-sized carrying forklift, then the local part of the storage battery assembly is forked into the installation chamber through the carrying forklift, one end, provided with the idler wheels, of the tray body faces towards the inside of the installation chamber, one end, provided with the baffle, of the tray body faces outwards, and finally the storage battery assembly is completely pushed into the installation chamber until one end, close to the idler wheels, of the storage battery assembly is in contact with the side wall inside the installation chamber. When the storage battery assembly needs to be replaced, the traction device is firstly installed on a small-sized carrying forklift, the bracket is fixed on a fork arm of the carrying forklift through the installation fixing mechanism, then the carrying forklift is driven to the side position of the installation chamber, the position of the fork arm on the carrying forklift is adjusted, the baffle plate on the tray body is inserted into the groove on the bracket, the fork arm of the carrying forklift is positioned below the installation chamber, the fork arm is lifted a certain distance, so that one end of the tray body is slightly lifted by the bracket, the roller on the tray body is contacted with the bottom surface of the installation chamber, then the storage battery assembly is pulled outwards through the carrying forklift, the storage battery assembly is completely pulled out of the installation chamber, after the storage battery assembly is completely pulled out of the installation chamber, the storage battery assembly falls onto the fork arm positioned below the storage battery assembly, the removed storage battery assembly is transported through the carrying forklift, and finally a new storage battery assembly is loaded into the installation chamber again, the specific installation procedure is as described above. The tray body is provided with the gyro wheel in one end, and when battery assembly was in pushing into the installation room, perhaps when pulling out battery assembly from the installation room, the gyro wheel can reduce the frictional force between battery assembly and the installation room bottom surface, is convenient for battery assembly at the indoor removal of installation.

When the battery assembly is completely pulled out from the mounting chamber and falls onto the fork arm, a certain height difference exists between the bottom of the battery assembly and the fork arm positioned below the battery assembly, and the battery assembly can generate large impact with the fork arm when falling onto the fork arm. According to the utility model, the airbag buffer device is arranged at the lower end of the tray body, so that the impact force of the storage battery assembly falling onto the fork arm can be reduced. The specific working principle of the air bag buffer device is as follows: when the storage battery assembly is completely installed in the installation chamber, the bolt on the safety rod is pulled out by the bolt pulling-out mechanism, the air bag buffer device is in a state to be triggered, at the moment, the lower end of the ejector rod is in contact with the bottom surface of the installation chamber, the lower piston is positioned above the through hole, at the moment, the first reactant cannot be in contact with the second reactant to react, and the buffer air bag is in a contracted state; when the storage battery assembly is pulled out of the mounting chamber, once the ejector rod is separated from the bottom surface of the mounting chamber, due to the fact that limitation of the bottom surface is lost, the first piston and the second piston move downwards under the action of the spring, the lower piston moves to the position below the through hole, at the moment, the second reactant in the second cavity is in contact with the first reactant in the first cavity, the first piston and the second piston react to generate a large amount of gas, the gas is filled into the buffering air bag through the inflation tube, the buffering air bag expands, the lower end of the buffering air bag is lower than the lower end face of the tray body after expansion, and therefore when the storage battery assembly falls onto the fork arm, the buffering air bag is in contact with the fork arm firstly, the buffering air bag plays a buffering role, and impact force of the storage battery assembly on the fork arm is effectively reduced.

When the storage battery assembly is not installed in the installation chamber, the telescopic rod and the piston rod are both in an extending state, the bolt is inserted in the bolt hole, and the upper piston and the lower piston cannot move downwards, so that the gas generating device cannot be triggered in an unnecessary state; after the storage battery assembly is completely installed in the installation chamber, the telescopic rod abuts against the inner wall of the installation chamber, the telescopic rod moves inwards, the first piston is pushed to move, the volume of the first oil chamber is reduced, hydraulic oil in the first oil chamber enters the second oil chamber through the connecting pipe, the second piston and the piston rod are pushed to move, the bolt is pulled out from the bolt hole, the safety of the gas generating device is relieved, and therefore when the storage battery assembly is pulled out from the installation chamber, the gas generating device can be triggered.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some technical features, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
