[0022] By adopting the above technical solution, it is possible to utilize the terminal connector 53 to be electrically connected to the control unit 2, and then utilize the feed assembly 563 to control the movement of the trapezoidal block 561 to lift the connection frame 52 and the terminal connector 53, thereby providing space for the assembly of the bidirectional converter 3, until the connection terminals of the bidirectional converter 3 are docked with the docking plate 51, control the trapezoidal block 561 to move to the initial position, and control the terminal connector 53 to automatically sleeve on the connection terminals of the bidirectional converter 3 under the action of the support assembly 54, thereby facilitating the rapid assembly of the bidirectional converter 3 after maintenance, thereby reducing the labor intensity of the staff.

[0023] Example 2: Please refer to Figure 1-3 On the basis of the first embodiment, the connection module 5 includes a docking plate 51, which is fixedly installed between the left and right side walls of the inner cavity of the energy storage inverter compartment 1. A connection frame 52 is fixedly connected to the top of the docking plate 51. A terminal connector 53 is slidably installed inside the connection frame 52.

[0026] By adopting the above technical solution, the bidirectional converter 3 is installed into the interior of the energy storage inverter compartment 1, so that the connecting terminal at the top of the bidirectional converter 3 is inserted into the docking groove on the docking plate 51, and then the trapezoidal block 561 is controlled to move to the initial position, so that the terminal connector 53 moves downward under the elastic action of the supporting spring, so that the terminal connector 53 is automatically sleeved on the connecting terminal at the top of the bidirectional converter 3, thereby realizing the rapid assembly of the bidirectional converter 3.

[0029] The working principle of the above embodiment is:

[0030] After the inspection and maintenance of the bidirectional converter 3 is completed, the portable backpack modular energy storage inverter compartment starts the electric push rod in the feed assembly 563 and controls the two trapezoidal blocks 561 to move to the opposite side, so that the moving trapezoidal block 561 lifts the connection frame 52 and the terminal connector 53, so that the terminal connector 53 compresses the support spring in the support assembly 54, and then the bidirectional converter 3 is installed into the interior of the energy storage inverter compartment 1, so that the connection terminal at the top of the bidirectional converter 3 is inserted into the docking groove on the docking plate 51, and then the trapezoidal block 561 is controlled to move to the initial position, so that the terminal connector 53 moves downward under the elastic action of the support spring, so that the terminal connector 53 is automatically connected to the connection terminal at the top of the bidirectional converter 3, thereby realizing the rapid assembly of the bidirectional converter 3.
