The extension spring 53 is sleeved on the insertion rod 52, a first end of the extension spring 53 is connected with the guide block 51, a second end of the extension spring 53 is connected with the insertion rod 52, and the extension spring 53 enables the first end of the insertion rod 52 to have a tendency of being inserted into the slot 21 of the movable frame 20. A first end of a cable 54 is connected to the plunger 52 and a second end of the cable 54 is connected to the lifter plate 42.
When the locking mechanism 50 is operated, the insert rod 52 is inserted into the insert groove 21 of the moving frame 20, so that the position of the moving frame 20 is locked. When the locking mechanism 50 is unlocked, the electric push rod 44 is contracted, the inserted rod 52 is pulled out of the slot 21 in the moving frame 20 under the action of the wire rope 54, and the position of the moving frame 20 can be moved under the action of external force, so that unlocking is completed.

In an emergency state, for example, when one of the storage batteries 25 is on fire, the wireless temperature sensor 30 detects that the temperature of the storage battery 25 exceeds a safety threshold, the control system judges that the storage battery 25 is in the emergency state, and reminds a driver to drive the passenger car to a safe area with few people nearby. At the moment, a driver firstly controls the cabin door 2 of the accommodation cabin 1 to be automatically opened; then the control system controls the electric push rod 44 to extend, so that the blade 43 at the bottom of the lifting plate 42 shears the wiring harness 70; finally, the electric push rod 44 is controlled to contract, the inserting rod 52 is pulled out of the slot 21 in the moving frame 20 under the action of the steel wire rope 54, and at the moment, the storage battery 25 in an emergency state is pushed out of the accommodating cabin 1 by the pressure spring 61, so that the storage battery leaves the passenger car and falls on the ground, and the safety of passengers on the passenger car is guaranteed.
It should be noted that when a certain emergency battery 25 is thrown out, the other batteries 25 can still supply power to the passenger car, so that the passenger car can still run. After the inserted link 52 leaves the slot 21, the moving frame 20 and the storage battery 25 can be thrown farther by the force instantaneously released by the pressure spring 61, so that the situation that the storage battery 25 impacts the vehicle body or the tire due to too close throwing is avoided, and the safety of passengers on the passenger car is further ensured.
In one embodiment, the bottom of the moving frame 20 is formed with a sealing frame 22 extending downward and parallel to the guide rail 10, and the bottom of the sealing frame 22 is attached to the bottom of the receiving compartment 1. The sealing frame 22 has a notch 23 at one end near the hatch 2.

The periphery of the sealing plate 81 is attached to the wall of the accommodating groove 3, and when the sealing plate 81 extends out of the accommodating groove 3, the sealing plate can form a sealing cavity 26 together with the sealing frame 22, the bottom of the moving frame 20 and the bottom of the accommodating chamber 1. The sealing plate 81 is provided with small air outlet holes 84. The first electromagnet 82 is installed at the bottom of the sealing plate 81, the second electromagnet 83 is installed at the bottom of the accommodating groove 3, and both the first electromagnet 82 and the second electromagnet 83 are electrically connected with the control system.
In a normal state, the first electromagnet 82 and the second electromagnet 83 are not energized, and the sealing plate 81 is hidden in the accommodation groove 3.
In a normal state, when the storage battery 25 needs to be replaced or repaired, a driver controls the cabin door 2 of the accommodation cabin 1 to be automatically opened. Then, the control system first energizes the first electromagnet 82 and the second electromagnet 83, so that the first electromagnet 82 and the second electromagnet 83 repel each other, and the sealing plate 81 extends out of the accommodating groove 3. Finally, the electric push rod 44 is controlled to contract, the inserted rod 52 is pulled out of the slot 21 in the moving frame 20 under the action of the wire rope 54, and the pressure spring 61 pushes the moving frame 20 to move towards the hatch door 2. When the sealing frame 22 at the bottom of the moving frame 20 contacts the sealing plate 81, a sealing chamber 26 is formed together with the sealing frame 22, the bottom of the moving frame 20 and the bottom of the receiving chamber 1. The pushing action of the pressure spring 61 can make the volume of the sealing cavity 26 gradually reduced, the gas in the sealing cavity 26 can be discharged through the small gas outlet hole 84 on the sealing plate 81, so that the pressure difference phenomenon can occur, the pushing action of the pressure spring 61 generates damping, the movement of the movable frame 20 is further blocked, the instant impact force brought to the movable frame 20 by the pressure spring 61 is weakened, and the movable frame 20 can stop until the back plate 27 of the sealing frame 22 contacts with the sealing plate 81.
The design utilizes the principle of orifice throttling, weakens the instant impact force of the moving frame 20, so that the moving frame 20 can be slowly stopped at the cabin door 2 finally, and the storage battery 25 is convenient for workers to replace or overhaul.
In one embodiment, a guide wheel 4 is installed on the wall of the accommodation chamber 1, and a second end of the wire rope 54 is connected to the lifting plate 42 after passing around the guide wheel 4. Under the action of the guide wheel 4, the first end of the wire rope 54 is in a horizontal state, and the second end of the wire rope 54 is in a vertical state, so that the lifting plate 42 can pull the insertion rod 52 better.
In one embodiment, the movable frame 20 is provided with a plurality of heat dissipation holes 24, and the heat dissipation holes 24 facilitate the heat of the storage battery 25 to be dissipated as soon as possible, which is beneficial to cooling the storage battery 25.
In one embodiment, a wire harness frame 5 is mounted on a sidewall of the first side of the moving frame 20. The harness frame 5 is for housing a harness 70 connected between the battery 25 and the vehicle body. The design of the wire harness frame 5 can better fix the position of the wire harness 70 and avoid the scattering of the wire harness 70.
In one embodiment, a stop block 6 is mounted on the bottom of the accommodation chamber 1 at a position far away from the door 2. And a pressure sensor 7 is arranged on the limiting block 6, and the pressure sensor 7 is electrically connected with a control system. When the moving frame 20 is in contact with the pressure sensor 7, the first end of the insertion rod 52 is aligned with the insertion slot 21 of the moving frame 20.
When the maintenance of the storage battery 25 is completed or the replacement of the storage battery 25 is completed, the worker puts the storage battery 25 into the moving frame 20. Then, the moving frame 20 is pushed toward the inside of the receiving chamber 1, and the compression spring 61 is compressed, when the moving frame 20 contacts the pressure sensor 7 on the stopper 6, indicating that the first end of the insertion rod 52 is aligned with the insertion groove 21 of the moving frame 20. And then the control system controls the electric push rod 44 to extend, the inserted rod 52 is inserted into the slot 21 of the movable frame 20 under the action of the tension spring 53, the position of the movable frame 20 is locked, and finally the wiring harness 70 of the storage battery 25 is connected with the wiring harness 70 between the vehicle body. This design facilitates the installation of the accumulator 25.
In one embodiment, the size of the plunger 52 is smaller than the size of the slot 21. This enables the insertion rod 52 to be inserted into the insertion slot 21 more easily, increasing the allowable error space.
In one embodiment, a telescoping pole is also included. The compression spring 61 is sleeved on the telescopic rod, one end of the telescopic rod is connected with the cabin wall of the containing cabin 1, and the other end of the telescopic rod is in contact with the movable frame 20.
