[0035] In the process of seat side impact, in order to ensure the test efficiency and reduce the test cost, such as Figure 1-Figure 3 As shown, the utility model provides a seat side impact test device. The seat side impact test device comprises a support base plate 1, a collision test frame 2, a test seat 3, a sliding guide assembly 4 and a buffer cylinder 6.
[0036] The collision test frame 2 is fixedly arranged at one end of the support base plate 1; the test seat 3 is slidably arranged on the support base plate 1. The sliding guide assembly 4 is arranged between the test seat 3 and the support base plate 1, and the test seat 3 can move toward or away from the collision test frame 2 through the sliding guide assembly 4 to collide or bounce off. The buffer cylinder 6 is arranged along the movement direction of the test seat 3, the piston rod 61 of the buffer cylinder 6 is connected to the test seat 3, and the cylinder body 62 of the buffer cylinder 6 is connected to the support base plate 1.
[0037] During the test, the buffer cylinder 6 replaces the existing honeycomb aluminum to play a buffering role, reducing the generation of consumables and waste. It not only meets the technical requirements but also reduces the cost. At the same time, there is no need to replace the honeycomb aluminum every time, which improves the test efficiency. In the present application, the buffer cylinder 6 can be a hydraulic cylinder or a pneumatic cylinder, and no excessive restrictions are made here.
[0038] Furthermore, the sliding guide assembly 4 includes a slide rail 41 and a slider 42. The slide rail 41 is fixedly arranged on the support base plate 1 along the movement direction of the test seat 3. The slider 42 is slidably arranged on the slide rail 41, and the slider 42 is fixedly connected to the test seat 3. In this embodiment, two slide rails 41 are arranged in parallel and spaced apart. Through the cooperation of the slider 42 and the slide rail 41, the smoothness of the sliding of the seat 3 relative to the support base plate 1 can be tested, which is convenient for testing the collision between the test seat 3 and the collision test frame 2.
[0039] Furthermore, the seat side impact test device further includes a shock absorbing assembly 5, which is fixedly arranged at the other end of the support base plate 1 and is used to reduce the shock of the test seat 3. By providing the shock absorbing assembly 5, the test seat 3 that rebounds after colliding with the collision test frame 2 can be buffered and reduced.
[0040] Furthermore, the shock absorbing assembly 5 includes an elastic shock absorber 51, which is fixedly arranged at the other end of the supporting base plate 1 and opposite to the collision test frame 2. By using the elastic shock absorber 51, the test seat 3 can be effectively buffered and shock-absorbed.

[0042] Further, an elastic buffer pad 32 is fixedly provided on one side of the test seat 3 facing the shock absorbing assembly 5. By providing the elastic buffer pad 32, it is possible to avoid a rigid collision between the test seat 3 and the elastic buffer, thereby avoiding damage to the test seat 3.
[0043] Furthermore, the elastic buffer pad 32 is made of rubber. Rubber has good elastic buffering performance and can play a good buffering role between the test seat 3 and the elastic shock absorber 51.

By rotatably connecting the buffer cylinder 6 to the first fixing seat 31 and the second fixing seat 11, the piston rod 61 of the buffer cylinder 6 can be prevented from being broken by shear force during the extension and retraction of the buffer cylinder 6.

The first fisheye joint 63 is rotatably matched with the first rotating shaft, and during the expansion and contraction of the buffer cylinder 6, there is a movable margin between the first fisheye joint 63 and the first rotating shaft, so that part of the shear force can be offset.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
