As a common form of traffic accidents, the safety performance test of side collision is particularly critical.

[0003] When conducting automobile side collision tests, the guide rail system is usually designed as a fixed structure, that is, the layout and inclination angle of the guide rail cannot be adjusted after installation. Since the guide rail cannot freely adjust the angle of travel, the test vehicle can only contact the side of the test vehicle at a single preset angle during side collision testing. This limitation results in the limitation of the test scenario, which cannot comprehensively cover various collision angles and speed combinations that may be encountered in actual traffic accidents. The data obtained is relatively single, making it difficult to fully and accurately reflect the real safety performance of the vehicle under different collision conditions. SUMMARY

[0030] The angle adjusting assembly 2 includes the translation plate 21, the rotary disc 23 is rotatably installed on the top of the translation plate 21 and close to the side of the base 1, the extension plate 24 is welded on the side of the rotary disc 23 away from the base 1, and the dynamic guide rail 4 is fixed in the middle of the top of the rotary disc 23 and the extension plate 24, the angle adjusting main body 29 for driving the rotary disc 23 to rotate is installed on the top of the translation plate 21.

[0031] The linear motor 291 drives the straight rack 292 to move laterally, and drives the vertical shaft 27 to rotate clockwise or counterclockwise under the meshing transmission action of the straight rack 292 and the circular rack 28, and then adjusts the angle of the movable guide rail 4 through the rotating disc 23, and then guides the impact trolley to impact the side of the test vehicle at different angles, so as to simulate various collision angles and speed combinations that may be encountered in actual traffic accidents as much as possible, so that the obtained data is comprehensive and complete, and the real safety performance of the vehicle under different collision conditions can be reflected.

[0032] As Figures 1 to 2 As shown in the drawings, in the embodiment, the translation assembly 5 includes an electric telescopic rod 51 installed inside the installation cavity 11, the movable end of the electric telescopic rod 51 is fixedly connected with a connecting column 52, and the end of the connecting column 52 away from the electric telescopic rod 51 is fixed to one side of the translation plate 21 close to the base 1. The electric telescopic rod 51 is shortened to pull the translation plate 21 to one side of the base 1 through the connecting column 52, so that the flat end 26 on the rotating disc 23 is in contact with the base 1, and the opposite ends of the movable guide rail 4 and the static guide rail 3 are in contact, so that a continuous guide rail line is formed therebetween, thereby ensuring that the impact trolley smoothly transitions from the static guide rail 3 to the movable guide rail 4. After the impact trolley transitions from the static guide rail 3 to the movable guide rail 4, the electric telescopic rod 51 is elongated to separate the movable guide rail 4 from the static guide rail 3, and there is a gap between them, thereby preventing the static guide rail 3 and the movable guide rail 4 from touching each other when the rotating disc 23 rotates, affecting the smooth rotation of the rotating disc 23, ensuring the stability of the angle adjustment assembly 2, and ensuring the accuracy of the impact angle adjustment of the impact trolley on the test vehicle, and improving the service life.

[0033] As Figures 1 to 3 As shown in the drawings, in the embodiment, the bottom of the translation plate 21 is provided with a plurality of groups of universal ball bearings 25, and the bottom of the extension plate 24 away from the rotating disc 23 is provided with two groups of universal ball bearings 22, and the rolling ends of the universal ball bearings 22 roll on the upper surface of the translation plate 21. When rotating and moving, the rolling of the universal ball bearings 22 and the universal ball bearings 25 respectively supports the translation plate 21 and the extension plate 24, so that the stability during movement is improved, and bending and breaking due to uneven stress is avoided, and the stability is better.

[0034] As Figures 2 to 4 As shown in the drawings, in the embodiment, the bottom of the rotating disc 23 is fixed with a vertical shaft 27 coaxial with the rotating disc 23, and the bottom end of the vertical shaft 27 is fixed to the top end of the translation plate 21. A circular rack 28 is sleeved on the vertical shaft 27. The angle adjustment body 29 includes a linear motor 291 fixed on the translation plate 21, and the movable end of the linear motor 291 is provided with a straight rack 292 engaged with the circular rack 28.

The mounting base 294 has a rack cavity 293 for fixing the rack 292 on the side near the vertical axis 27.

[0036] like Figures 2 to 4 As shown in the figure, in this embodiment, the angle adjustment body 29 also includes a slide rail 296 fixed on the translation plate 21, and a slider 295 that slides on the slide rail 296 is fixed at the bottom of the mounting base 294. The rack 292 is mounted on the mounting base 294, and the mounting base 294 supports the mounting base 294 through the sliding of the slider 295 and the slide rail 296, that is, it supports the rack 292, so that the force on the rack 292 is evenly distributed on the translation plate 21, ensuring the accuracy and stability of the meshing between the rack 292 and the circular rack 28.

[0037] like Figures 2 to 3 As shown in the figure, in this embodiment, the rotating disk 23 has a flat end 26 on the side near the pad 1, and the flat end 26 and the end face of the moving guide rail 4 near the stationary guide rail 3 are on the same vertical plane.

[0038] When in use, place the vehicle to be tested on the side of the angle adjustment component 2 away from the pad 1, and make the side of the test vehicle face the angle adjustment component 2. The electric telescopic rod 51 shortens and pulls the translation plate 21 to one side of the pad 1 through the connecting column 52, so that the flat end 26 on the rotating disk 23 abuts against the pad 1.

[0039] The impact trolley moves on two stationary guide rails 3. The two stationary guide rails 3 limit the travel path of the impact trolley, so that the impact trolley can only move at high speed in a straight line. When the impact trolley transitions from the stationary guide rail 3 to the moving guide rail 4, the electric telescopic rod 51 extends to separate the moving guide rail 4 from the stationary guide rail 3, and there is a gap between them, so as to prevent the stationary guide rail 3 and the moving guide rail 4 from touching each other when the rotating disk 23 is rotating.

[0040] The linear motor 291 drives the rack 292 to move laterally. Under the meshing transmission of the rack 292 and the circular rack 28, the vertical shaft 27 is driven to rotate clockwise or counterclockwise. The angle of the moving guide rail 4 is adjusted by the rotating disk 23, thereby guiding the impact trolley to impact the side of the test vehicle at different angles.
