[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment of a power battery fixing device, comprising a base 1 and four fixing plates 2 12, the fixing plate 2 12 is arranged on the top of the base 1, the inside of the base 1 is rotatably connected with a cross plate 2, the outside of the cross plate 2 is rotatably connected with four connecting plates 3, the other side of the connecting plate 3 is rotatably connected with a slider 4, the slider 4 is slidably connected to the middle part of the base 1, the side of the slider 4 away from the connecting plate 3 is fixedly connected with a fixing plate 1 5, the fixing plate 1 5 and the top of the fixing plate 2 12 are both fixedly connected with a mounting plate 11, when the cross plate 2 rotates and under the action of the connecting plate 3, the slider 4 can be retracted into the base 1, and then the fixing plate 1 5 can be driven to clamp the battery, thereby improving the speed of fixing the battery, and at the same time, different types of batteries can be clamped, and there is no need to replace the base 1 to adjust the clamping range of the fixing plate 1 5, thereby reducing the cost required for fixing the battery, a limited position component is arranged between the base 1 and the fixing plate 1 5, and the middle part of the base 1 is rotatably connected with a driving component.

[0032] Reference Figure 1-Figure 3 The limit assembly includes a plurality of limit rods 6, which are evenly distributed on the outside of the base 1. The fixed plate 5 is slidably connected to the outside of the limit rod 6. The outer periphery of the limit rod 6 away from the base 1 is threadedly connected with a stopper 7. The fixed plate 5 contacts the stopper 7. The limit rod 6 can limit the fixed plate 5, which can maintain the parallel movement of the fixed plate 5 and reduce the pressure on the slider 4, so that the fixed plate 5 can be more fully in contact with the battery, thereby improving the clamping stability. The driving assembly includes a rotating rod 10, which is rotatably connected to the middle part of the base 1. The end of the rotating rod 10 close to the base 1 is fixedly connected with a worm 8. The bottom of the cross plate 2 is rotatably connected with a worm wheel 9. The worm 8 and the worm wheel 9 are meshed with each other. The worm 8 can drive the worm wheel 9 to rotate by rotating the rotating rod 10. At the same time, the worm wheel 9 can rotate the cross plate 2 when rotating, so that the battery can be conveniently clamped.

[0033] Reference Figure 3-Figure 4A positioning block 13 is fixedly connected to the bottom of the fixing plate 12, and the positioning block 13 is slidably connected to the middle part of one of the mounting plates 11. A positioning groove 19 is provided at the top of the mounting plate 11, and the positioning block 13 is plugged into and matched with one of the positioning grooves 19. The positioning block 13 can be limited by the positioning groove 19. When the positioning block 13 enters the positioning groove 19 in the mounting plate 11 at the top of the fixing plate 15, the fixing plate 15 and the fixing plate 2 12 can be aligned and connected, thereby accelerating the installation speed between the fixing plate 15 and the fixing plate 2 12. The interiors of the two mounting plates 11 are fixedly connected with a compression spring 14, and the other end of the compression spring 14 is fixedly connected with a card block 15, and the positioning block 13 is in contact with one of the card blocks 15. A card slot 16 is provided in the middle of the positioning block 13, and one of the card blocks 15 is plugged into and matched with the card slot 16.

[0034] Reference Figure 3-Figure 4 When the positioning block 13 enters the positioning groove 19, the positioning block 13 will contact the card block 15, and then squeeze the card block 15 so that the card block 15 compresses the compression spring 14 and receives it into the mounting plate 11. At this time, the positioning block 13 can be fully entered. When the card slot 16 moves to the original position of the card block 15, the card block 15 is not squeezed by external force and the card block 15 can be bounced into the card slot 16 under the action of the compression spring 14. Then, after the fixing plate 1 5 and the fixing plate 2 12 are connected, they can be fixed between them. When the number of batteries is large or the height is high, the clamping range can be increased, and the clamping height can be adjusted to meet different needs.

[0035] Reference Figure 1-Figure 4 A disassembly component is slidably connected to the middle part of the mounting plate 11, and the disassembly component includes a protrusion 17, which is slidably connected to the middle part of the mounting plate 11, and the protrusion 17 is fixedly connected between the compression spring 14 and the block 15. The block 15 can be pulled out of the middle part of the slot 16 by pushing the protrusion 17, so that the fixed plate 1 5 and the fixed plate 2 12 can be quickly separated. A limiting groove 20 is provided on the outer side of the mounting plate 11, and the protrusion 17 is specifically slidably connected to the middle part of the limiting groove 20. The protrusion 17 can be limited by the limiting groove 20 to prevent the protrusion 17 from tilting or offsetting when moving, thereby avoiding the problem that the block 15 tilts and cannot move or generates large wear between the mounting plate 11.

[0036] Reference Figure 1-Figure 4 A gasket 18 is fixedly connected to one side of the plurality of fixing plates 1 5 and the plurality of fixing plates 2 12 close to the base 1. The gasket 18 can protect the clamped battery to prevent damage to the outside of the battery during the clamping process.

[0037] Working principle: When in use, multiple batteries are welded into a battery pack and placed on the top of the base 1. At this time, the worm 8 can drive the worm wheel 9 to rotate by rotating the rotating rod 10. When the worm wheel 9 rotates, the cross plate 2 can drive one side of the connecting plate 3 to move. At the same time, the other side of the connecting plate 3 can drive the slider 4 to move toward the base 1, so that the fixed plate 5 can clamp and fix the battery pack.

[0038] Among them, when the number of batteries is large and higher than the fixing plate 15, by inserting the positioning block 13 into the middle of the mounting plate 11 on the top of the fixing plate 15, the positioning block 13 will squeeze the card block 15 when entering and make the card block 15 compress the compression spring 14, so that the positioning block 13 can completely enter the mounting plate 11, and when the card slot 16 moves to the original position of the card block 15, the card block 15 can be bounced into the card slot 16 under the action of the compression spring 14, and then the fixing plate 15 and the fixing plate 2 12 can be connected. At this time, a large number or a higher battery pack can be effectively clamped, and the card block 15 and the card slot 16 can be separated by pushing the protrusion 17, so that the fixing plate 15 and the fixing plate 2 12 can be quickly separated.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
