New energy vehicles include hybrid electric vehicles, pure electric vehicles, fuel cell vehicles, hydrogen engine vehicles, gas vehicles, and alcohol ether vehicles. New energy vehicles are composed of power batteries, vehicle chassis, vehicle bodies, and vehicle electrical appliances.

[0003] New energy vehicle batteries can be divided into several categories such as lead-acid batteries, nickel-metal hydride batteries, and lithium batteries. When new energy vehicle batteries leave the factory, the battery quality will be detected, including the detection of battery collisions. At present, the detection methods for battery collisions are relatively single, lacking detection methods for batteries with local and side collisions. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that there is no detection for local and side collisions of new energy vehicle batteries in the collision detection of new energy vehicle batteries, and to propose a battery testing device for new energy vehicles.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A battery testing device for new energy vehicles, which includes a base, a telescopic cylinder, a support plate, a first collision block, a collision mechanism, two support seats, and a battery body.

A guide chute is opened on the top of the base. The collision mechanism is slidably connected in the guide chute, and the collision mechanism is located between the first collision block and the two support seats.

The bottom of the fixed plate is slidably connected in the guide chute. The collision plate, the collision column, and the side collision blocks are all located between the fixed plate and the support base. The three sliding blocks all penetrate the fixed plate and are slidably connected to the fixed plate. The ends of the three sliding blocks are respectively fixedly connected to the collision plate, the collision column, and the side collision blocks.

[0008] As a further description of the above technical solution:

[0009] The sliding blocks, the collision plate, and the collision column are all cylindrical in shape. The diameter of the collision plate is larger than that of the sliding block, and the diameter of the collision column is smaller than that of the sliding block. The diameters of the three sliding blocks are all equal.

[0010] As a further description of the above technical solution:

[0011] The distance between the support plate, the fixed plate, and the support base is not greater than the length of the sliding block.

[0012] As a further description of the above technical solution:

[0013] The support base is made of a high-hardness elastic material.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-3 , the present invention provides a technical solution: a new energy vehicle battery testing device, including a base 1, a telescopic cylinder 2, a support plate 3, a first collision block 4, a collision mechanism 5, two support seats 6 and a battery body 7. The support plate 3 and the two support seats 6 are both fixedly installed on the top of the base 1. The telescopic cylinder 2 is fixedly installed on the support plate 3. The first collision block 4 is fixedly connected to the telescopic end of the telescopic cylinder 2, and the first collision block 4 is located between the support plate 3 and the two support seats 6. A guide chute 8 is opened on the top of the base 1. The collision mechanism 5 is slidably connected in the guide chute 8, and the collision mechanism 5 is located between the first collision block 4 and the two support seats 6. The battery body 7 is arranged in the gap 9 formed between the two support seats 6;

[0023] The collision mechanism 5 includes a fixed plate 51, three sliding blocks 52, a collision plate 53, a collision column 54 and a side collision block 55. The bottom of the fixed plate 51 is slidably connected in the guide chute 8. The collision plate 53, the collision column 54 and the side collision block 55 are all located between the fixed plate 51 and the support seat 6. The three sliding blocks 52 all penetrate the fixed plate 51 and are slidably connected to the fixed plate 51. The ends of the three sliding blocks 52 are respectively fixedly connected to the collision plate 53, the collision column 54 and the side collision block 55;

[0024] The sliding block 52, the collision plate 53, and the collision column 54 are all cylindrical in shape. The diameter of the collision plate 53 is larger than that of the sliding block 52, and the diameter of the collision column 54 is smaller than that of the sliding block 52. The diameters of the three sliding blocks 52 are all equal. By using the sliding block 52, the collision plate 53, the collision column 54, and the side collision block 55, it is possible to detect the corresponding battery body 7 during frontal collision, local collision, and side collision. Multiple detection methods for the battery body 7 meet the battery detection results of new energy vehicles under different collision conditions, and the practicability is better;

[0025] The distance between the support plate 3, the fixed plate 51, and the support base 6 is not greater than the length of the sliding block 52;

[0026] The support base 6 is made of a high-hardness elastic material, which reduces the secondary damage to the battery body 7 caused by surrounding fixtures during the collision detection of the new energy battery body 7, ensuring the accuracy of the precise measurement results.

[0027] Working principle: First, start the telescopic cylinder 2. At this time, the telescopic cylinder 2 extends, driving the first collision block 4 to move and collide with the collision mechanism 5. When testing the frontal collision, it collides with the collision plate 53 and the sliding block 52 in the collision mechanism 5, thereby detecting the collision between the collision plate 53 and the battery body 7 and detecting the frontal collision situation of the battery body 7 when the new energy vehicle has a frontal collision. By the same principle, when testing the local collision, move the fixed plate 51 along the guide chute 8 so that the sliding block 52 on the fixed plate 51 is aligned with the first collision block 4. The movement of the telescopic cylinder 2 drives the first collision block 4 to move, thereby causing the collision column 54 and the sliding block 52 to move, and then testing the detection situation of the local collision of the battery body 7. When testing the side collision, move the fixed plate 51 so that the side collision block 55 is aligned with one of the side edges of the battery body 7. Thus, when the sliding block 52 moves, the side collision block 55 can collide with the battery body 7, detecting the side collision situation of the battery body 7 when the new energy vehicle has a side collision, thereby realizing a multi-directional detection method for the new energy vehicle battery and improving the practicability of the device.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
