Description

Technical Field

[0001] The utility model relates to the technical field of collision test benches, in particular to a multi-position collision test bench. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and new vehicle-mounted power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. Currently, most common new energy vehicles are powered by electricity, and battery packs are an indispensable component of new energy vehicles. Since cars often encounter unexpected situations and collisions while driving on the road, in order to improve the safety of new energy vehicles, it is necessary to conduct collision tests on the produced battery packs, which also requires the use of collision test benches.

[0003] The patent publication number of the inspection institute is CN213544207U, which discloses an impact collision test bench, including a bottom plate, a side plate, a top plate, a clamp body support plate, a clamp body lower plate, a stud, a clamp body upper plate, a locking nut, a slide rail, a slider, an inverted T-shaped collision body frame, a sensor, and a collision body. The upper end of the inverted T-shaped collision body frame is plugged into the top plate through a rectangular through hole, a pulley support plate is provided on one side of the upper end of the top plate, a pulley used in conjunction with the pulley support plate is provided on the upper end of the pulley support plate, a rope used in conjunction with the pulley is provided on the pulley, one end of the rope is connected to the middle of the upper end of the inverted T-shaped collision body frame, the side plate and the slide rail, and the slider and the inverted T-shaped collision body frame are all connected by threads, and the top plate and the pulley support plate, and the pulley support plate and the pulley are all connected by bolts. Compared with the prior art, the advantages of the utility model are: high flexibility and good use effect.

[0004] However, this patent still has some shortcomings. Since the car may be subjected to collisions from all directions during actual use, the battery pack needs to be fully tested. However, this type of collision test bench can only perform a single-surface collision test on the top of the battery pack through a collision body during the experiment. Therefore, during the experiment, the staff is required to constantly move the battery pack and turn the test surfaces on the battery pack to test them in turn. The operation steps are cumbersome and time-consuming, resulting in low efficiency of the collision test. In addition, it is also laborious for the staff to frequently move the battery pack, and the labor intensity during the test is high.

[0005] To this end, we propose a multi-position crash test rig. Utility Model Content
