[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings: The specific structure of this utility model is shown below. Figures 1-2As shown, its main structure includes base 10, rotary disc 20 which is revolved matched on base 10 around horizontal axis and support plate 30 which is fixed at the center of the end face of rotary disc 20 and arranged horizontally. Among them, the top surface of support plate 30 is connected with test plate 40 for fixing battery pack through support spring 42 at four corners, and the bottom of test plate 40 is installed with vibration motor 43. During test detection, the battery pack is fixed on test plate 40, and through the rotation of rotary disc 20, the overturning action of support plate 30 and test plate 40 can be driven, so as to realize the test detection of the battery pack under the overturning and tilting working conditions. During the overturning process, since the battery pack is fixed on the test plate 40 instead of the support plate 30, that is, the battery pack is arranged eccentrically away from the rotation axis, so that when the rotary disc 20 rotates, the battery pack makes eccentric overturning or tilting compound motion, which is more accurate for detection under overturning and tilting working conditions. In addition, the vibration force of test plate 40 can be generated through vibration motor 43, and the shock absorber of automobile can be simulated by using support spring 42, so that the battery plate makes small amplitude high frequency vibration under the double action of vibration force of vibration motor 43 and support spring 42, thereby simulating the small amplitude high frequency vibration of automobile when passing through long distance potholed road section. Through the simulation test detection of battery pack under different working conditions, the accuracy of the detection of battery pack coolant leakage is improved.

[0024] On the basis of the above, Figure 1 As shown, rotary disc 20 is arranged as two groups of coaxial interval distribution, and support plate 30 is fixed at the axis between the two rotary discs 20, so as to stably support the two ends of support plate 30 and prevent support plate 30 from being broken under long time rotation, thereby prolonging the service life of support plate 30.

[0025] Further, as shown in the drawings, Figure 1 As shown, rotary motor 11 is installed on base 10 to drive the rotation of rotary disc 20, which is more labor-saving and can effectively control the speed of rotary disc 20 compared with manual rotation of rotary disc 20.

[0026] On the basis of the above, Figure 1 As shown, suction cup 60 is installed on the upper surface of test plate 40, and the battery pack is fixed on the upper surface of test plate 40 through suction cup 60. The suction cup 60 has the advantages of high efficiency and convenience in fixing the battery pack. Specifically, suction cup 60 can be negative pressure vacuum suction cup 60, or traditional rubber suction cup 60, which can fix the battery pack on test plate 40. Of course, in actual implementation, other fixing methods in the prior art can also be used, such as bolt cooperation with pressing plate locking and fixing, or cylinder straight stroke power mechanism driving clamping plate to clamp and fix the battery pack.

[0027] It is worth mentioning that, as shown in the drawings, Figure 1As shown, in order to prevent the battery pack from causing potential safety hazard due to high temperature during test, the utility model discloses a water cooling pipe 41 is installed on the upper surface of the test board 40, and the water cooling pipe 41 is connected with the water supply assembly through the connecting hose 411 to cool the battery pack on the test board 40.

[0028] Specifically, as shown, Figure 1 The water cooling pipe 41 is in S-shaped structure, which ensures the uniformity of the coverage of the test board 40 and the cooling effect of the test board 40.

[0029] In addition, as shown, Figure 1 The water supply assembly comprises a water tank 50 and a water pump 51 connected with the water tank 50, and the water inlet end and the water outlet end of the water cooling pipe 41 are connected with the output end of the water pump 51 and the water tank 50 respectively through the connecting hose 411. During operation, the cooling water in the water tank 50 is guided into the water cooling pipe 41 through the water pump 51, and finally flows back to the water tank 50 through the connecting hose 411, so that the recycling of the cooling water can be realized.

[0030] Further, as shown, Figure 1 The connecting hose 411 is in spiral structure, which reduces the resistance of the connecting hose 411 to the rotation of the test board 40 and ensures that the test board 40 can rotate smoothly.
