[0042] When the present invention is in use, the battery box 5 is fixedly installed with the chassis of the new energy electric vehicle through the fixed eaves plate 511, and the battery panel 6 is installed inside the battery box 5. The battery panel 6 is connected to the connection plug 510 through the connection slot 603 to drive and supply power to the vehicle;

[0043] When a new energy vehicle is out of power and breaks down on a highway and needs to be replaced, a new energy mobile battery replacement vehicle drives on the highway for rescue. The new energy mobile battery replacement vehicle drives to the position of the rescue vehicle to make the positioning synchronization column 407 face the direction opposite to the positioning plug 512. At this time, the lifting screw 305 is rotated by controlling the operation of the screw power box 306 to drive the lifting support plate 3 to move up and down. The lifting support plate 3 moves to a suitable height, so that the positioning synchronization column 407 is opposite to the positioning plug 512, and then the load-bearing plate 1 reverses and moves back, so that the positioning synchronization column 407 is slowly inserted into the positioning plug 512;

[0044] The supporting movable plate 4 is movably installed with the lifting support plate 3 through the supporting structure, such as Figure 6As shown, the supporting movable plate 4 can swing and displace on the horizontal plane when there is a deviation in the direction between the positioning synchronization plug column 407 and the positioning plug tube 512, so as to adapt to a small deviation, thereby facilitating the plug-in cooperation between the positioning synchronization plug column 407 and the positioning plug tube 512. The supporting movable plate 4 can be manually rotated to move and deflect for guidance. When the supporting movable plate 4 is not subjected to external force, it can automatically return to a straight state through the elastic tension of the reset tension spring 310, as shown in FIG. Figure 1 As shown in;

[0045] After the positioning synchronization pin 407 is plugged into the positioning plug tube 512 and is in place, the conduction pin 514 is plugged into the power supply hole 408 and is connected, and the conduction pin 514 is powered through the power supply hole 408, so that the rotary power box 505 is operated, thereby driving the fixing bolt 502 to rotate, so that the fixing bolt 502 is moved out of the battery screw hole 601, so that the battery panel 6 is released;

[0046] The telescopic hydraulic column 402 controls the telescopic latch 403 to extend, so that the telescopic latch 403 is inserted into the traction ear 602, and the traction hydraulic rod 406 is retracted to pull out the solar panel 6;

[0047] After the battery panel 6 is pulled out to a certain extent, the telescopic hydraulic column 402 controls the telescopic latch 403 to retract, and then the battery panel 6 is driven to move to the central position of the supporting movable plate 4 through the rotation of the movable plate driving roller 410. At this time, the carrying plate truck 1 moves forward, so that the positioning synchronization plug column 407 is pulled out from the positioning plug tube 512, and then the lifting support plate 3 is lifted and moved, so that the supporting movable plate 4 is facing the blank layer inside the battery exchange storage warehouse 2, and then the movable plate driving roller 410 and the layer plate driving roller 203 rotate together to move the low-power battery panel 6 to the top of the partition layer plate 201 of the corresponding blank layer for storage; the lifting and lifting of the lifting support plate 3 drives the supporting movable plate 4 to lift and move, and similarly, the fully charged battery panels 6 on other layers inside the battery exchange storage warehouse 2 are moved to the central position of the supporting movable plate 4, and the supporting movable plate 4 is lowered again, and the carrying plate truck 1 reverses again, so that the positioning synchronization plug column 407 is inserted into the positioning plug tube 512;

[0048] Reverse the above process, first make the movable plate driving roller 410 drive the battery panel 6 to move, after reaching the appropriate position, the telescopic hydraulic column 402 controls the telescopic bolt 403 to extend, so that the telescopic bolt 403 is inserted into the traction ear 602, and the traction hydraulic rod 406 is extended, so that the battery panel 6 is pushed into the installation battery box 5, and after reaching the position, the telescopic bolt 403 is retracted, and the rotating power box 505 drives the fixing bolt 502 to rotate, so that the battery panel 6 is fixed to the installation battery box 5; thus, the battery replacement is completed, and at this time the load-bearing plate vehicle 1 moves forward, so that the positioning synchronization plug column 407 can be pulled out from the positioning plug tube 512;

[0049] When the new energy mobile battery exchange vehicle is driving on a muddy road and the wheels are stuck, the hydraulic impact member 311 controls the impact push rod 312 to extend and then retract in a cycle, so that the supporting movable plate 4 is pushed and shakes back and forth. Since the impact push rod 312 is facing the rear of the vehicle, Fig.10 As shown, when it is extended impactively, it will rigidly impact the surface of the supporting movable plate 4, so that the vehicle obtains a forward thrust. After the impact top rod 312 is retracted, the supporting movable plate 4 is flexibly reset under the elastic force of the reset spring 310, so that the reaction force exerted on the vehicle backward is more moderate. The thrust difference between the reaction forces is utilized to increase the vehicle's ability to escape from trouble, so that the new energy mobile battery exchange vehicle can adapt to more road surfaces and increase rescue scenarios.
