[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Example: Refer to Figures 1 to 5A protective cover for battery pack management includes a mounting frame 1, a protective cover 2 is arranged on the mounting frame 1, and both ends of the protective cover 2 are provided with a clamping assembly, the clamping assembly includes a placement groove 5 opened at the top of the mounting frame 1, a "∩"-shaped pressing plate 4 is slidably installed in the placement groove 5, a main sliding column 6 is fixedly installed in the placement groove 5, and slave sliding columns 7 are fixedly installed on both sides of the main sliding column 6 in the placement groove 5, and the slave sliding column 7 is located above the main sliding column 6, and both ends of the protective cover 2 are provided with a slide groove 9, and a slide groove 9 is slidably installed in the slide groove 9 There is a card column 10, and a spring 11 is fixedly installed at one end of the card column 10 close to the main sliding column 6, and the other end of the spring 11 is fixedly connected to the inner wall of the slide groove 9. The opposite inner side of the pressure plate 4 is fixedly installed with a traction rope 8. The other end of the traction rope 8 passes through the back of the sliding column 7, passes through the interlayer between the placement groove 5 and the slide groove 9, and is fixedly connected to the card column 10. A card slot that can be connected with each card column is opened on the inner wall of the installation frame 1; when the protective cover plate 2 is not installed, the card assembly is in a natural state, and the spring 11 is in its original state. When the protective cover 2 is to be installed on the installation frame 1, the pressure plate 4 is pressed downward. When the pressure plate 4 moves downward, the traction ropes 8 at both ends are driven to move downward. The traction ropes 8 are pressed on the slave slide column 7. The traction ropes 8 pull the clamping column 10 toward the placement groove 5 through the main slide column 6 and the slave slide column 7. At this time, the clamping assembly is in the installation state. When the clamping column 10 moves into the slide groove 9, the protective cover 2 is placed in the installation frame 1, and then the pressure on the pressure plate 4 is released. The traction ropes 8 no longer stretch the clamping column 10, and the clamping column 10 slides to the corresponding After being inserted into the card slot 12, the compressed spring 11 also rebounds, and the rebounded spring 11 squeezes the card column 10 into the card slot 12, so that the protective cover 2 is fixed in the installation frame 1, and the installation of the protective cover 2 is completed. The protective cover 2 is fixed by the card column 10, the spring 11 and the card slot 12. The connection method is simple and efficient, which avoids the problem of loosening of the protective cover 2 caused by rust of the bolts when using bolts for installation, reduces the maintenance cost, and ensures the maintenance and disassembly efficiency of the protective cover 2.

[0024] Specifically, a "∩"-shaped support frame 3 is fixedly installed on the top of the protective cover 2. The support frame 3 is located above the pressure plate 4. A screw rod 15 is threadedly connected to the support frame 3. The screw rod 15 passes through the support frame 3 and is rotatably connected to the pressure plate 4. When installing the protective cover 2, the screw rod 15 is turned, and the pressure plate 4 is pressed down when the screw rod 15 rotates. When the clamping column 10 is located in the slide groove 9, the rotation of the screw rod 15 is stopped. The self-locking property of the screw rod 15 prevents the pressure plate 4 from moving upward due to the elastic force of the spring 11, which is convenient for the operator to put the protective cover 2 into the installation frame 1.

[0025] Furthermore, a limit ring 16 is fixedly mounted on the bottom end of the screw rod 15 ; the limit ring 16 can prevent the screw rod 15 from being separated from the pressure plate 4 when rotating.

[0026] Furthermore, limit strips 13 are fixedly installed on both sides of the card column 10, and a limit groove 14 is opened in the slide groove 9 to limit and slide with the limit strip 13; the card column 10 is slidably connected to the slide groove 9 through the limit strip 13 and the limit groove 14, and the limit strip 13 and the limit groove 14 ensure that the card column 10 will not rotate due to the spring 11 when sliding in the slide groove 9, thereby avoiding twisting of the traction rope 8.

[0027] Furthermore, a groove 17 is provided on both the main sliding column 6 and the slave sliding column 7, and the traction rope 8 is located in the groove (17), and the cross-sectional diameter of the traction rope 8 is smaller than the width of the groove 17; when the traction rope 8 slides on the main sliding column 6 and the slave sliding column 7, it is located in the groove 17, and the groove 17 can prevent the traction rope 8 from being deviated.

[0028] Furthermore, a sealing gasket 18 is fixedly installed on the inner side of the installation frame 1 ; the sealing gasket 18 is made of silicone material, and the sealing gasket 18 can enhance the sealing between the installation frame 1 and the protective cover plate 2 .

[0029] The working principle of the device is as follows: when the protective cover 2 is not installed, the clamping assembly is in a natural state, and the spring 11 is in its original state. When the protective cover 2 needs to be installed on the installation frame 1, the screw rod 15 is rotated, and the screw rod 15 drives the pressure plate 4 to move downward. When the pressure plate 4 moves downward, it drives the traction ropes 8 at both ends to move downward. The traction rope 8 is pressed on the slave slide column 7, and the traction rope 8 pulls the clamping column 10 toward the placement groove 5 through the main slide column 6 and the slave slide column 7. At this time, the clamping assembly is in the installation state. When the clamping column 10 moves into the slide groove 9, the protective cover 2 is placed in the installation frame 1, and then the screw rod 15 is rotated in the opposite direction to release it. When the pressure plate 4 is pressed, the traction rope 8 no longer stretches the clamping column 10. After the clamping column 10 slides into the corresponding clamping groove 12, the compressed spring 11 also rebounds. The rebounded spring 11 squeezes the clamping column 10 into the clamping groove 12, thereby fixing the protective cover 2 in the installation frame 1, completing the installation of the protective cover 2. The protective cover 2 is fixed by the clamping column 10, the spring 11 and the clamping groove 12. The connection method is simple and efficient, avoiding the problem of loosening of the protective cover 2 caused by rust of the bolts when using bolts for installation, reducing the maintenance cost, and ensuring the maintenance and disassembly efficiency of the protective cover 2.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
