[0002] New energy batteries are divided into two categories: storage batteries and fuel cells. Storage batteries are applicable to pure electric vehicles, and fuel cells are specifically used for fuel cell electric vehicles. When manufacturing new energy batteries, workers will use a bump test device to test the anti-bump ability of new energy batteries.
[0003] When the existing bump test device for new energy batteries is in use, the degree of bump is mostly fixed. Therefore, when in use, it is not convenient for workers to test new energy batteries with different bump degrees, which brings certain inconvenience to workers during the production and processing of new energy batteries. Summary of the Utility Model

[0021] The following will describe two implementation manners of the present application in detail with reference to the accompanying drawings.
[0022] The first implementation manner:
[0023] Figures 1-4 There is shown a bump test device for a new energy battery, including a test bench 1. On a pair of side ends of the test bench 1, a fixed frame one 2 and a fixed frame two 3 are respectively fixedly connected. On the side end of the fixed frame one 2, an electric push rod one 4 is fixedly connected. On the telescopic end of the electric push rod one 4, a push plate 5 is fixedly connected. On the side end of the fixed frame two 3, an electric push rod two 6 is fixedly connected. Those skilled in the art can make the best selection for the models of the electric push rod one 4 and the electric push rod two 6, such as ETS-50. On the output end of the electric push rod two 6, a reinforcement frame 7 is fixedly connected. Above the test bench 1, there is a box body one 8 and a box body two 9. The side end of the box body one 8 is fixedly connected with the push plate 5. On the upper end of the test bench 1, a rectangular groove 10 is opened. Inside the rectangular groove 10, a plurality of rectangular plates 11 are slidably inserted. On the upper ends of the rectangular plates 11, a plurality of round tubes 12 are fixedly connected. On a pair of side ends of the rectangular plates 11, a plurality of limiting grooves 13 are opened. Inside the limiting grooves 13, limiting tubes 14 are inserted. On a pair of side ends of the test bench 1, a plurality of limiting holes 15 are opened;
[0024] The side end of the box body one 8 is in contact with the side end of the box body two 9. The lower ends of the box body one 8 and the box body two 9 are both in contact with the upper ends of the round tubes 12. The end of the limiting tube 14 away from the rectangular plate 11 movably penetrates through the limiting hole 15 and extends out of the limiting hole 15. On a pair of side ends of the rectangular plates 11, plug-in blocks 16 are fixedly connected. On a pair of inner side walls of the rectangular groove 10, a plurality of plug-in grooves 17 for movably inserting the plug-in blocks 16 are opened. The length of the box body two 9 is equal to the inner wall length of the reinforcement frame 7. When the box body two 9 moves, the outer end of the box body two 9 is in contact with the inner wall of the reinforcement frame 7.
[0025] During use, place the battery between the box body one 8 and the box body two 9. Start the electric push rod two 6, and make its telescopic end push the reinforcement frame 7 towards the box body two 9 until the inner wall of the reinforcement frame 7 is in contact with the outer end of the box body two 9. When the box body two 9 moves, the reinforcement frame 7 can limit a pair of side ends of the box body two 9, improving its stability on the round tubes 12. Then start the electric push rod one 4, and make its telescopic end push the push plate 5, so that the push plate 5 pushes the box body one 8 and the box body two 9 to move on the round tubes 12. At the same time, the electric push rod two 6 will drive the reinforcement frame 7, making the reinforcement frame 7 move synchronously with the box body two 9 (as shown in Figure 3 ), and during the movement, the inner wall of the reinforcement frame 7 always remains in contact with the side end of the box body two 9, thereby completing the bump test. Finally, take out the battery and observe its damage degree;
[0026] When adjusting the magnitude of the bumpiness, pull up the corresponding rectangular plate 11, so that the circular tube 12 at its upper end is driven to move upward together, thereby adjusting the height difference between the circular tubes 12 on two adjacent rectangular plates 11. After adjusting the height difference between the circular tubes 12, pass the limiting tube 14 through the limiting hole 15 and insert it into the limiting groove 13 to fix the rectangular plate 11 and the circular tube 12. Finally, repeat the above steps and use different bumpiness to test the battery;
[0027] In summary, when the device is in use, it can test the battery under different bumpiness, and the operation steps are simple, which is convenient for personnel to use when processing and testing the battery.
[0028] The second embodiment:
[0029] On the basis of the first embodiment, this embodiment adds structures such as the moving frame 18, and the rest is the same as the first embodiment.
[0030] Figures 5-6 It is shown that one end of the box body 8 close to the box body 9 is fixedly connected with a moving frame 18. A sliding groove 19 for the moving frame 18 to be movably inserted is opened at one end of the box body 9 close to the box body 8. Threaded tubes 20 are threadedly connected to both side ends of the box body 9, and a plurality of docking grooves 21 for the threaded tubes 20 to be movably inserted are opened at both side ends of the moving frame 18.
[0031] When in use, it is necessary to move the box body 8 and the box body 9 away from each other. When the box body 8 moves, the moving frame 18 moves in the sliding groove 19 and gradually moves out of the sliding groove 19, thereby adjusting the distance between the box body 8 and the box body 9. Finally, fix the moving frame 18 in the sliding groove 19 by using the threaded tube 20, so as to fix the box body 8 and the box body 9. Therefore, the device can test batteries of different sizes.
[0032] Combined with the current actual requirements, the above-mentioned embodiments adopted in this application, the protection scope is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of the present invention.
