[0002] New energy batteries refer to batteries that use renewable energy or other environmentally friendly energy for charging and energy storage. Compared with traditional fossil energy batteries, they have higher energy density, longer service life and lower environmental pollution.

At the same time, new energy batteries, as automotive energy storage devices, need to be charged and discharged quickly. During the charging and discharging process, the battery will generate heat. The existing shell has poor heat dissipation effect, and the heat will accumulate inside the shell, causing the temperature inside the shell to rise, resulting in a decrease in battery performance and even causing safety problems.

DETAILED DESCRIPTION

[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Reference Figure 1 , Figure 2 and Figure 4 As shown, a new energy battery safety protection shell comprises a protective shell 1 and a top cover 2 which is tightly fitted with the upper end of the protective shell 1, a sliding sleeve 3 is fixedly connected at the four corners of the inner bottom end of the protective shell 1, a sliding rod 4 is slidably connected inside the sliding sleeve 3, a spring damper 5 is fixedly connected between the inner bottom ends of the sliding rod 4 and the sliding sleeve 3, a fixing plate 6 which is tightly fitted with the inner wall of the protective shell 1 is fixedly connected to the upper end of the sliding rod 4, a plurality of evenly distributed through holes 7 are penetrated through the upper end of the fixing plate 6, and a plurality of evenly distributed through holes 7 are formed in the middle of the inner bottom end of the protective shell 1. A fan 8 is fixedly installed at the center, and the wind direction of the fan 8 is vertically upward. A plurality of strip-shaped heat dissipation grooves 9 are fixedly opened on the left and right sides of the protective shell 1. A battery body 10 is arranged at the center of the upper end of the fixing plate 6. The wind is blown upward by the fan 8. The wind generated by the fan 8 is blown to the surface of the battery body 10 through the through hole 7, which can cool the battery body 10. At the same time, the hot air inside the protective shell 1 will be discharged outward through the heat dissipation groove 9, which can avoid the temperature inside the protective shell 1 being too high, resulting in a decrease in battery performance or even causing safety problems.

[0025] Reference Figure 1 and Figure 3As shown, the left and right inner walls of the protective shell 1 are fixedly connected with a threaded rod 11, the outer surface of the threaded rod 11 is threadedly connected with a threaded sleeve 12, and the end of the threaded sleeve 12 is fixedly connected with a circular push plate 13. The left and right inner walls of the protective shell 1 are located on the front and rear sides of the threaded rod 11 and are fixedly connected with two telescopic rods 14, and the ends of the telescopic rods 14 are fixedly connected with clamping blocks 16. The outer surface of the telescopic rod 14 is sleeved with a reset spring 15, and the reset spring 15 is fixedly connected between the clamping block 16 and the left and right inner walls of the protective shell 1. The inner side of the clamping block 16 is fixedly connected with a first buffer pad 21. By rotating the threaded sleeve 12, the push plate 13 can be driven to push the clamping block 16 close to the left and right sides of the battery body 10 for clamping. By rotating the threaded sleeve 12 in the opposite direction, the push plate 13 will move away from the clamping block 16. At this time, the clamping block 16 can be reset under the action of the reset spring 15.

[0026] Furthermore, a sliding groove 17 is provided at the upper end of the clamping block 16, and two sliding blocks 18 are slidably connected inside the sliding groove 17. The top of the sliding block 18 is higher than the top of the clamping block 16, and the ends of the two sliding blocks 18 that are away from each other are fixedly connected to a guide rod 19, and the other end of the guide rod 19 passes through the inner wall of the sliding groove 17 and is fixedly connected to a side plate 20. The outer surface of the guide rod 19 is sleeved with a second spring 29, and the inner side of the side plate 20 is fixedly connected to a second buffer pad 22. Pulling the sliding block 18 outward can enable the guide rod 19 to push the side plate 20 to move outward while compressing the second spring 29. After releasing the sliding block 18, the side plate 20 will shrink inward under the action of the elastic force of the second spring 29, thereby clamping the front and rear sides of the battery body 10.

[0027] A plurality of first springs 23 are fixedly connected to the lower end of the top cover 2, an upper pressure plate 24 is fixedly connected to the other end of the first spring 23, a vibration-damping rubber pad 25 is fixedly connected to the lower end of the upper pressure plate 24, the vibration-damping rubber pad 25, the first buffer pad 21 and the second buffer pad 22 can absorb impact force and vibration, and reduce the impact and vibration on the battery body 10, docking holes 27 are opened at the four corners of the upper end of the protective shell 1, and a connecting hole 26 is opened at the corresponding position of the upper end of the top cover 2 and the docking hole 27, and a fixing screw 28 is connected to the internal thread of the connecting hole 26 and the docking hole 27.

[0028] Working principle: When the device is in use, the battery body 10 is first placed at the center of the upper end of the fixing plate 6, and then the sliding block 18 is pulled outward so that the guide rod 19 pushes the side plate 20 to move outward while compressing the second spring 29. At this time, the threaded sleeve 12 is rotated so that the push plate 13 pushes the first buffer pad 21 on the clamping block 16 close to the left and right sides of the battery body 10 for clamping. When the first buffer pad 21 is completely in contact with the left and right sides of the battery body 10, the sliding block 18 is released. Under the action of the elastic force of the second spring 29, the side plate 20 will shrink inward so that the second buffer pad 22 is close to the front and rear sides of the battery body 10. The protective shell 1 is clamped on the side, and then the top cover 2 is covered, and the top cover 2 is connected and fixed through the connecting hole 26, the docking hole 27 and the fixing screw 28. When the protective shell 1 is working normally, the wind generated by the fan 8 is blown to the surface of the battery body 10 through the through hole 7, thereby cooling the battery body 10. At the same time, the hot air inside the protective shell 1 will be discharged outward through the heat dissipation groove 9. When the shell is subjected to external impact force, the impact force is reduced in the vertical direction by compressing the spring damping 5 and the first spring 23, and the impact force is absorbed in the horizontal direction by the first buffer pad 21 and the second buffer pad 22, thereby reducing the magnitude of the impact force.
