[0002] New energy vehicles mainly consist of a battery drive system, a motor system, an electric control system and assembly, etc. Among them, the motor, electric control and assembly are basically the same as those of traditional vehicles, and the difference lies in the battery drive system.

[0003] Reference Publication (Announcement) No.: CN218725161. The utility model discloses a testing device for the research and development of new energy power batteries, which relates to the technical field of battery safety data testing. The utility model includes a bottom plate, and a telescopic support plate is arranged at the upper end of the bottom plate. In this scheme, the fixing of the battery is realized by setting components such as long rods and threaded rods, so that the drop test of the battery can be carried out. However, in the above scheme, the distance between each long rod is not adjustable, so that different-sized batteries cannot be fixed by the threaded rod, resulting in limitations when the battery pack enters the test and insufficient practicability. Therefore, it is necessary to redesign a testing device for the research and development of new energy power batteries for the above problems. Summary of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

The limiting rod 8 slidably penetrates the moving sleeve 9, and the limiting rod 8 can limit the moving sleeve 9, so that the moving sleeve 9 can only axially move along the outer wall of the screw rod 6.

[0023] The outer wall of the moving sleeve 9 is fixedly connected to a connecting plate 11 through a connecting mechanism. The connecting mechanism includes a connecting rod 10 fixedly installed on the outer wall of the moving sleeve 9. The end of the connecting rod 10 is fixedly connected to the upper end surface of the connecting plate 11. Two sliding rods 13 are fixedly installed on the bottom wall of the connecting plate 11 through a moving frame 12. Sliding sleeves 15 are slidably installed on the outer walls of the two sliding rods 13 through a stabilizing mechanism. The stabilizing mechanism includes a stabilizing rod 14 fixedly installed inside the moving frame 12. The stabilizing rod 14 slidably penetrates the sliding sleeve 15, and the stabilizing rod 14 can limit the sliding sleeve 15, so that the sliding sleeve 15 can only axially move along the outer wall of the sliding rod 13.

[0024] Toothed plates 16 are fixedly installed on the outer walls of the two sliding sleeves 15. A third motor 17 is fixedly installed on the upper end surface of the connecting plate 11. Gears 18 that engage with the two toothed plates 16 are fixedly installed on the outer wall of the output shaft of the third motor 17. Clamping plates 21 are fixedly connected to the outer walls of the two sliding sleeves 15 through a connecting mechanism. The connecting mechanism includes a connecting rod 20 fixedly installed on the outer wall of the sliding sleeve 15.

[0025] When the utility model is used, the bottom plate 1 can be conveniently moved by a plurality of pulleys 2. When the battery pack is viewed from the side, the second motor 7 can drive the screw rod 6 to rotate, and the screw rod 6 drives the movable sleeve 9 to move by cooperating with the limit rod 8, thereby the movable sleeve 9 can drive the connecting plate 11 to move downward by cooperating with the connecting rod 10, so that the connecting plate 11 can drive the two clamping plates 21 to be located at the outer wall of the battery pack, and then the third motor 17 drives the gear 18 to rotate, and the gear 18 can bite the two toothed plates 16 when rotating, so that the two toothed plates 16 can respectively drive the two sliding sleeves 15 to slide on the outer wall of the sliding rod 13 through the cooperation of the stabilizing rod 14, so that the two sliding sleeves 15 can respectively drive the two clamping plates 21 to move and approach each other through the cooperation of the connecting rod 20, so that the two clamping plates 21 clamp and fix the battery pack, and under the bite of the gear 18 and the toothed plate 16, the spacing between the two clamping plates 21 can be conveniently adjusted, so that battery packs of different sizes can be clamped and fixed;

[0026] After the battery pack is clamped and fixed, the second motor 7 can drive the screw 6 to reverse, thereby driving the battery pack to move upward, and then the third motor 17 reverses, which can make the two clamping plates 21 move away from each other, thereby releasing the clamping of the battery pack, and then the battery pack can be drop tested. When the battery pack needs to be subjected to an anti-puncture test, the first motor 4 can drive the lifting frame 5 to move, thereby driving the clamped and fixed battery pack to move to the upper end surface of the storage frame 22, and then the cylinder 23 can drive the nail plate 24 to move upward. At this time, the clamping plate 21 can release the fixation of the battery pack, and the battery pack falls on the upper end surface of the nail plate 24 to complete the anti-puncture test.
