[0014] S1. Simultaneously start the electric telescopic rods on both sides, and make one electric telescopic rod extend and the other electric telescopic rod retract. The electric telescopic rod starts to drive the sleeve to move, and the sleeve movement drives the plug to move. The plug moves and slides inside the slide groove through the ball bearing. At the same time, the plug moves and docks with the socket. At this time, the plug can transmit the power of the battery through the first wire, the conductive rod and the second wire. When the power of one of the batteries is about to run out, the sleeve drives the plug to move by controlling the extension and contraction of the two electric telescopic rods, so as to achieve the effect of docking with another power source;

[0015] S2. The movement of the sleeve drives the movement of the U-shaped rod, and the movement of the U-shaped rod drives the movement of the aluminum-based heat-conducting plate. When the plug and the socket are connected, the aluminum-based heat-conducting plate fits with the aluminum-based heat-conducting frame on the surface of the corresponding battery.

[0016] S3, open the sealing plate, and then pull the two traction rods toward the middle at the same time through the operation port. The movement of the traction rods drives the trapezoidal block to move.

At this time, the battery is taken out of the placement slot;

[0017] S4. After placing a new battery in the placement slot, press down the protection frame. At this time, the protection frame drives the sleeve to descend. The sleeve descends to allow the U-shaped rod to be inserted into the linkage slot through the socket. The U-shaped rod is inserted into the linkage slot and contacts the inclined surface at the bottom of the trapezoidal block, so that the two trapezoidal blocks move toward the middle and compress the spring. After the U-shaped rod is inserted into the sleeve, the spring ejects the trapezoidal block through the elastic force. At this time, the trapezoidal block limits and fixes the U-shaped rod through the limiting opening, thereby achieving the effect of facilitating the replacement of batteries.

[0018] Beneficial Effects

[0019] The present invention provides a new energy power switching device and method. Compared with the existing technology, it has the following beneficial effects:

[0020] (1) The new energy power switching device and method starts the electric telescopic rods on both sides at the same time, and makes one electric telescopic rod extend and the other electric telescopic rod retract. The electric telescopic rod starts to drive the sleeve to move, and the sleeve movement drives the plug to move. The plug moves and slides inside the slide groove through the ball bearing. At the same time, the plug moves and docks with the socket. At this time, the plug can transmit the power of the battery through the first wire, the conductive rod and the second wire. When the power of one of the batteries is about to run out, the sleeve drives the plug to move by controlling the extension of the two electric telescopic rods, so as to achieve the effect of docking with another power source, thereby effectively avoiding the situation where the device stops running due to the inability of one of the electric telescopic rods to store power.

[0021] (2) The new energy power switching device and method simultaneously starts the electric telescopic rods on both sides, and makes one electric telescopic rod extend and the other electric telescopic rod retract. The electric telescopic rod starts to drive the sleeve to move, and the movement of the sleeve drives the U-shaped rod to move. The movement of the U-shaped rod drives the aluminum-based heat-conducting plate to move. When the plug and the socket are connected, the aluminum-based heat-conducting plate fits with the aluminum-based heat-conducting frame on the surface of the corresponding battery. At this time, the heat generated by the battery during operation will be transmitted to the aluminum-based heat-conducting plate through the aluminum-based heat-conducting frame, and then transmitted to the water inside the frame through the aluminum-based heat-conducting plate, thereby achieving the effect of heat dissipation protection for the battery.

[0022] (3) The new energy power switching device and method, by opening the sealing plate, and then pulling the two traction rods toward the middle at the same time through the operating port, the movement of the traction rod drives the trapezoidal block to move, and after the trapezoidal block moves to the outside of the U-shaped rod, the protection frame can be pulled up to separate the protection frame from the placement frame. At this time, the battery can be taken out of the placement slot, and after replacing the new battery, the protection frame is pressed down. At this time, the U-shaped rod is inserted into the linkage slot through the socket. After the U-shaped rod is extended into the sleeve, the spring ejects the trapezoidal block through the elastic force. At this time, the trapezoidal block limits and fixes the U-shaped rod through the limit port, thereby achieving the effect of facilitating the replacement of the battery.

When the power of one of the batteries 4 is about to run out, the sleeve 6 drives the plug 8 to move by controlling the two electric telescopic rods 5 to extend and retract, so as to achieve the effect of docking with another power source;

[0040] S2, the movement of the sleeve 6 drives the U-shaped rod 21 to move, and the movement of the U-shaped rod 21 drives the aluminum-based heat-conducting plate 18 to move. When the plug 8 and the socket 14 are connected, the aluminum-based heat-conducting plate 18 fits with the aluminum-based heat-conducting frame 20 on the surface of the corresponding battery 4.

[0041] S3, open the sealing plate 29, and then pull the two traction rods 26 toward the middle at the same time through the operation port 28, so that the traction rods 26 move and the trapezoidal block 24 moves, and after the trapezoidal block 24 moves to the outside of the U-shaped rod 21, the protection frame 1 can be pulled up to separate the protection frame 1 from the placement frame 2, and the battery 4 is taken out of the placement slot 3;

[0042] S4. After placing a new battery 4 in the placement slot 3, the protection frame 1 is pressed down. At this time, the protection frame 1 drives the sleeve 6 to descend. The sleeve 6 descends to allow the U-shaped rod 21 to be inserted into the linkage slot 12 through the socket 22. The U-shaped rod 21 is inserted into the linkage slot 12 and contacts the inclined surface at the bottom of the trapezoidal block 24, so that the two trapezoidal blocks 24 move toward the middle and compress the spring 23. After the U-shaped rod 21 is extended into the sleeve 6, the spring 23 ejects the trapezoidal block 24 through the elastic force. At this time, the trapezoidal block 24 limits and fixes the U-shaped rod 21 through the limiting opening 25, thereby achieving the effect of facilitating the replacement of the battery 4.
