[0033] 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.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The utility model provides an embodiment: a new energy vehicle battery protection device, including a base 1, a plurality of bottom plates 2 are fixedly connected to the upper surface of the base 1, a mounting plate 3 is arranged on the top of each bottom plate 2, an extrusion block 1 4 is fixedly connected to the upper surface of the bottom plate 2, an extrusion block 2 5 is fixedly connected to the lower surface of the mounting plate 3, a fixing frame 6 is fixedly connected to the opposite side of the bottom plate 2 and the mounting plate 3, a damper 8 is fixedly connected to the lower surface of the extrusion block 2 5, an output end of the damper 8 is fixedly connected to the upper surface of the extrusion block 1 4, and a sliding frame 7 is slidably connected to the side wall of the extrusion block 1 4 and the sliding frame 7 The side wall is fixedly connected with a side frame 9, and a sliding block 10 is slidably connected inside the side frame 9. The side walls of the fixing frame 6 are all rotatably connected with a connecting plate 11, and one end of the connecting plate 11 is rotatably connected to the side wall of the sliding block 10. A rubber column 12 is fixedly connected between the mounting plate 3 and the bottom plate 2. A mounting assembly is arranged on the top of the mounting plate 3, and a battery body 13 is arranged on the upper surface of the mounting plate 3. The mounting assembly includes a mounting frame 14 and a side plate 15. The lower surface of the mounting frame 14 is fixedly connected to the upper surface of the mounting plate 3, and the side wall of the side plate 15 is fixedly connected to the side wall of the battery body 13. The mounting frame 14 and the side plate 15 are connected by bolts;

[0035] When the device vibrates during use, the force generated by the vibration will cause the mounting plate 3 to slide downward. The sliding of the mounting plate 3 will cause the extrusion block 25 to be squeezed into the interior of the sliding frame 7, and at the same time, the connecting plate 11 will be squeezed and deflected. One side of the connecting plate 11 will rotate on the fixing frame 6, and the other side will rotate on the sliding block 10. While the connecting plate 11 rotates, the sliding block 10 is pushed to both sides to reduce the distance between the mounting plate 3 and the bottom plate 2, and the force generated by the vibration is transferred to the inside of the damper 8. The damper 8 can alleviate and weaken the force generated by the vibration. In this process, the rubber column 12 will be deformed, and the rubber column 12 plays the role of assisting the damper 8 to weaken the force generated by the vibration. When the force dissipates, the rubber column 12 will reset, so that the device returns to its original state. Through the above scheme, the impact of vibration on the battery body 13 is reduced, and the service life of the battery body 13 is extended.

[0036] Reference Figure 2 , Figure 5 and Figure 6 A protective cover 16 is slidably connected to the upper surface of the base 1, a cooling fan 17 is fixedly connected inside the protective cover 16, a battery 18 is fixedly connected to the side wall of the protective cover 16, the cooling fan 17 and the battery 18 are connected by wires, a card slot 19 is provided inside the protective cover 16, a positioning block 20 is fixedly connected inside the base 1, a sleeve 21 is fixedly connected to the side wall of the positioning block 20, a slide rod 23 is slidably connected inside the sleeve 21, a spring 22 is arranged inside the sleeve 21, one end of the spring 22 is fixedly connected to the side wall of the positioning block 20, and the other end of the spring 22 is fixedly connected to the side wall of the positioning block 20. It is connected to the side wall of the slide bar 23, and the side wall of the slide bar 23 is fixedly connected to a slide block 24. The side wall of the slide block 24 is slidably connected to the inside of the base 1. A block 25 is fixedly connected to the upper surface of the slide block 24. The side wall of the block 25 is slidably connected to the inside of the card slot 19. A rotating shaft 26 is rotatably connected to the inside of the base 1. The side wall of the rotating shaft 26 penetrates the base 1 and the positioning block 20 and extends to the outside. A rotating plate 27 is fixedly connected to the side wall of the rotating shaft 26. A connecting plate 28 is rotatably connected to the side wall of the rotating plate 27. One side of the connecting plate 28 is rotatably connected to the side wall of the slide block 24. A turntable 29 is fixedly connected to the side wall of the rotating shaft 26.

[0037] During the use of the battery body 13, when the temperature is too high, the cooling fan 17 can be started, which can effectively reduce the temperature of the battery body 13 and prevent the battery from being damaged by overheating. The storage battery 18 will supply power to it to ensure its heat dissipation efficiency. When the battery body 13 needs to be repaired, the staff can operate the rotating shaft 26 through the turntable 29. The rotation of the rotating shaft 26 will simultaneously drive the rotating plates 27 on both sides to rotate. This rotation allows the connecting plate 28 to move relatively. During this process, the slider 24 will slide toward the middle inside the base 1, thereby pulling the card block 25 out of the inside of the card slot 19. At this time, it is only necessary to lift the protective cover 16 to remove it from the base 1 to complete the disassembly work. After the maintenance is completed, the staff can operate the turntable 29 again to rotate the rotating plates 27 on both sides. This rotation drives one side of the connecting plate 28 to rotate on the rotating plate 27, and the other side to rotate on the slider 24, while pulling the slider 24 to move toward the middle inside the base 1. During this process, the slide bar 23 will pressurize the spring 22 to shrink it. Then, put the protective cover 16 back on the surface of the base 1, insert the card block 25 into the inside of the card slot 19, loosen the turntable 29 to reset the slider 24 to both sides, and clamp the card block 25 in the inside of the card slot 19 to complete the installation. This design makes the installation and removal of the protective cover 16 more convenient and improves work efficiency. Through the above scheme, not only the safety of the battery body 13 during use is guaranteed, but also the maintenance work is made easier. Through the effective heat dissipation of the cooling fan 17, the life of the battery body 13 is extended, ensuring the stable operation of the equipment. During the maintenance process, the staff can easily remove and install the protective cover 16, reducing the difficulty of maintenance work.

[0038] Working principle: When the equipment vibrates during use, the force generated by the vibration will cause the mounting plate 3 to slide downward and squeeze the extrusion block 25 into the interior of the sliding frame 7. When the mounting plate 3 moves downward, the connecting plate 11 will be squeezed and deflected. One side of the connecting plate 11 will rotate on the fixing frame 6, and the other side will rotate on the sliding block 10 while pushing the sliding block 10 to both sides, thereby reducing the distance between the mounting plate 3 and the bottom plate 2, and transferring the force generated by the vibration to the inside of the damper 8. The damper 8 will alleviate and weaken the force generated by the vibration. At the same time, the rubber column 12 will deform, and the auxiliary damper 8 will weaken the force generated by the vibration. When the force dissipates, the rubber column 12 will reset, thereby driving the mounting plate 3 to reset, achieving a buffering effect, reducing the impact of the force generated by the vibration on the battery body 13, and extending its service life. When the temperature of the battery body 13 is overheated, the cooling fan 17 can be started to dissipate the heat of the battery body 13 to avoid damage caused by excessive temperature. When the battery body 13 needs to be repaired, the staff can The rotating disk 29 rotates the rotating shaft 26, so that it drives the rotating plates 27 on both sides to rotate at the same time. The rotation of the rotating plates 27 drives the connecting plates 28 on both sides to move relatively, so that the slider 24 slides inward inside the base 1, and the card block 25 is pulled out from the inside of the card slot 19. At this time, the protective cover 16 is lifted up to remove it from the base 1, and the disassembly work is completed. The battery body 13 is inspected and repaired. After the inspection is completed, the rotating disk 29 is rotated again to drive the rotating plates 27 on both sides to rotate, so that one side of the connecting plate 28 rotates on the rotating plate 27, and the other side of the connecting plate 28 rotates on the rotating plate 27. One side will pull the slider 24 while rotating on it, so that it moves inward inside the base 1, and pressurizes the spring 22 through the slide bar 23 to shrink it. At this time, the protective cover 16 is placed back on the surface of the base 1, and the card block 25 is inserted into the inside of the card slot 19. After the placement is completed, the turntable 29 is released. At this time, the spring 22 loses pressure and resets, pushing the slider 24 to both sides, and making the card block 25 stuck in the inside of the card slot 19, thereby completing the installation of the protective cover 16, achieving the effect of facilitating the installation and disassembly of the protective cover 16.
