The top of the threaded sleeve 12 is fixedly connected to the bottom of the connecting base 3. A first motor 13 is fixedly connected to the movable base frame 1 to drive the adjusting screw 11 to rotate. By starting the first motor 13, the adjusting screw 11 is driven to rotate on the top of the movable base frame 1, causing the threaded sleeve 12 to rise and fall on the outer surface of the adjusting screw 11, thereby pushing the connecting base 3 to rise and fall as a whole, raising the battery to a suitable height.

[0026] Please refer to it again. Figure 1 The top of the mobile base frame 1 is fixedly connected to a telescopic rod 2, and the connecting base 3 is fixedly connected to the telescopic end of the telescopic rod 2. There are four telescopic rods 2, which are distributed at the four corners of the bottom of the connecting base 3. As an adjustable rod, the telescopic rod 2 plays an important role in many fields due to its flexibility and practicality. The telescopic rod 2 improves the stability of the connecting base 3 during the lifting process.

[0027] Please refer to it again. Figure 1 , Figure 2 and Figure 5 One end of the placement seat 4 is hinged to one end of the connecting base 3 via a pin. Connecting plates for the connecting pin are fixed on both sides of the connecting base 3. Multiple rollers 5 supporting the battery are rotatably connected to the top of the placement seat 4. Under the action of the rollers 5, the friction at the bottom of the battery is changed to rolling friction, which facilitates the movement of the battery on the rollers 5. The connecting base 3 is provided with a flipping mechanism to drive the placement seat 4 to flip. A sliding groove 31 is opened on the top of the connecting base 3, and a bottom groove 41 is opened on the bottom of the placement seat 4. A sliding block 32 is slidably connected inside the sliding groove 31. A pressing rod 34 is hinged to the top of the sliding block 32 via a pin. One end of the pressing rod 34 extends into the bottom groove 41 and is hinged to the bottom groove 41 via a pin. By driving the sliding block 32 to slide inside the sliding groove 31, the pressing rod 34 presses the placement seat 4 to flip around the pin at one end of the placement seat 4, so that the placement seat 4 is adjusted to an inclined position, and the battery can slide off under the action of the rollers 5.

[0028] Please refer to it again. Figure 1 , Figure 2 and Figure 5The sliding groove 31 is rotatably connected to a rotating screw 33, and the sliding block 32 is threadedly connected to the rotating screw 33. One end of the connecting base 3 is fixedly connected to a second motor 35 that drives the rotating screw 33 to rotate.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A fixing plate 6 is fixedly connected inside the placement seat 4. The fixing plate 6 has an insertion hole 61. One end of the limiting rod 7 is inserted into the insertion hole 61. Multiple limiting rods 7 are used to restrict the area around the battery and prevent the limiting rod 7 from sliding on the roller 5. The inner wall of the insertion hole 61 has a vertical sliding groove 62 and an annular sliding groove 63. The vertical sliding groove 62 and the annular sliding groove 63 are interconnected. A sliding stop 71 is fixedly connected to the outer surface of one end of the limiting rod 7. The sliding stop 71 slides inside the vertical sliding groove 62. When the limiting rod 7 is inserted into the fixing plate 6, the sliding stop 71 is aligned with the vertical sliding groove 62, so that the limiting rod 7 is inserted into the fixing plate 6. Then, by rotating the limiting rod 7, the sliding stop 71 is rotated into the annular sliding groove 63 to prevent one end of the limiting rod 7 from being pulled out of the fixing plate 6. This utility model embodiment also provides an automotive battery swapping device, including the above-mentioned protective device.

[0030] Working principle: By moving the device to the bottom of the vehicle, the first motor 13 is started to drive the adjusting screw 11 to rotate. Under the action of the threaded sleeve 12, the connecting base 3 is pushed up, so that the placement seat 4 is raised to a suitable position. After the vehicle's waste battery is removed and placed on the roller 5, the placement seat 4 is controlled to descend as a whole, and the device is moved to a suitable position. The second motor 35 is started to drive the rotating screw 33 to rotate, and the sliding block 32 is controlled to slide inside the sliding groove 31. The squeezing rod 34 pushes the placement seat 4 to rotate around the pin shaft. Under the action of the roller 5, the waste battery is easily unloaded. The new battery is placed on the roller 5. One end of the limiting rod 7 is inserted into the inside of the fixed plate 6. When the limiting rod 7 is inserted into the inside of the fixed plate 6, the sliding stop 71 is aligned with the vertical sliding groove 62, so that the limiting rod 7 is inserted into the inside of the fixed plate 6. Then, by rotating the limiting rod 7, the sliding stop 71 is rotated into the inside of the annular sliding groove 63 to prevent one end of the limiting rod 7 from being pulled out of the inside of the fixed plate 6. Multiple limiting rods 7 are used to limit the area around the battery to ensure that the battery can rise stably to the replacement position.
