[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] Example 1:

[0031] Please refer to Figure 1-4A battery module replacement auxiliary device for an automotive battery pack includes a counterweight plate 1. A vertical plate 2 is fixedly connected to the top of the counterweight plate 1. A drive box 3 is fixedly connected to the left side of the vertical plate 2. A servo motor 4 is fixedly installed on the top of the inner cavity of the drive box 3. A screw 5 is fixedly connected to the output end of the servo motor 4. A rectangular plate 6 is threaded onto the outer surface of the screw 5. A drive plate 7 is fixedly connected to the right side of the rectangular plate 6. A protective frame 8, which works in conjunction with the vertical plate 2, is fixedly connected to the right side of the top of the counterweight plate 1. A lifting plate 9 is fixedly connected to the right side of the drive plate 7, penetrating the vertical plate 2. A support plate 10 is fixedly connected to the top of the lifting plate 9. Battery modules, which work in conjunction with the protective frame 8, are evenly stacked on the top of the support plate 10. The main body 11 has a limit component 12 at the bottom left side of the drive box 3. A guide plate 14 is fixedly connected to the left side of the rectangular plate 6. A guide groove 15 that works with the guide plate 14 is opened on the left side of the inner cavity of the drive box 3. The outer surface of the guide plate 14 is slidably connected to the inner surface of the guide groove 15. The bottom of the screw 5 is rotatably connected to the drive box 3 through a bearing. A moving groove that works with the lifting plate 9 is opened on one side of the vertical plate 2. Universal wheels 16 are movably connected to the four corners of the bottom of the counterweight plate 1. A handle 17 is fixedly connected to the top left side of the drive box 3. A temporary storage platform 18 is fixedly connected to the right side of the top of the protective frame 8. Protective pads are fixedly connected to the opposite sides of the protective frame 8 and the vertical plate 2.

[0032] In this embodiment: By setting up a counterweight plate 1, a vertical plate 2, a drive box 3, a servo motor 4, a screw 5, a rectangular plate 6, a drive plate 7, a protective frame 8, a lifting plate 9, and a bearing plate 10, this utility model can conveniently stack and protect the battery module body 11, and at the same time, facilitate its lifting and loading. By setting up the above structure, it can have an auxiliary lifting and loading function, thereby meeting the user needs of customers and effectively reducing the labor intensity of workers.

[0033] Example 2:

[0034] Reference Figure 2 The limiting component 12 includes a horizontal plate 121. The right side of the horizontal plate 121 is fixedly connected to the drive box 3. A stud 122 is threadedly connected to the top of the horizontal plate 121. The bottom of the stud 122 passes through the horizontal plate 121 and is rotatably connected to a limiting plate 123 through a bearing. A crank 13 is fixedly connected to the top of the stud 122. A rubber pad is fixedly connected to the bottom of the limiting plate 123.

[0035] In this embodiment: By setting a horizontal plate 121, a stud 122 and a limiting plate 123, the present invention can conveniently press and limit the device to prevent movement.

[0036] The implementation principle of this utility model is as follows: When it is necessary to replace the battery module body 11 of the battery pack, the staff uses the handle 17 and the universal wheel 16 to move the device to the designated position on the maintenance workbench of the battery pack. At the same time, the temporary storage platform 18 is closely attached to the maintenance workbench and kept on the same horizontal plane. Then, the staff turns the crank handle 13, which drives the stud 122 to rotate on the inner surface of the horizontal plate 121. This causes the stud 122 to drive the limiting plate 123 to move downward, thereby causing the limiting plate 123 to drive the rubber pad to move downward and press against the ground, thereby achieving the pressing and limiting positioning of the device and preventing it from moving.

[0037] Next, the staff connected the device to the mains power. When it was necessary to load and install the battery module body 11, the staff activated the external controller of the servo motor 4, causing the output end of the servo motor 4 to drive the screw 5 to rotate on the inner surface of the rectangular plate 6. This caused the rectangular plate 6 to drive the drive plate 7 to move upward, the drive plate 7 to drive the lifting plate 9 to move upward, and the lifting plate 9 to drive the support plate 10 to move upward. This caused the support plate 10 to drive the stacked battery module bodies 11 to move upward, thus moving the uppermost battery module body 11 out of the inner cavity of the protective frame 8. Then, the staff pushed the battery module body 11 to move it to the top of the maintenance workbench via the temporary storage platform 18, thus facilitating the moving and installation of the battery module body 11. Then, the staff activated the servo motor 4 again, causing the servo motor 4 to... The output end drives the screw 5 to rotate on the inner surface of the rectangular plate 6, causing the rectangular plate 6 to drive the drive plate 7 to move upward again. The drive plate 7 drives the lifting plate 9 to move upward again, causing the lifting plate 9 to drive the bearing plate 10 to move upward again. This causes the bearing plate 10 to drive the stacked battery module bodies 11 to move upward again, so that the uppermost battery module body 11 moves out of the inner cavity of the protective frame 8. Then, the staff pushes the battery module body 11 to move it through the temporary storage platform 18 to the top of the maintenance workbench, realizing the continuous replacement of the battery module body 11. This cycle is repeated to realize the complete loading, replacement and installation of the battery module body 11. The device is simple to operate and easy to use for auxiliary lifting and loading replacement, thus meeting the needs of customers and effectively reducing the labor intensity of staff.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
