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

[0024] Please refer to Figures 1 to 4 In the embodiment of the present utility model, a collision safety test device includes a bottom plate 1. A fixed seat 2 is fixedly connected to the front end of the bottom plate 1. A cover body 3 is fixedly connected to the top surfaces of the fixed seat 2 and the bottom plate 1. One side of the cover body 3 away from the fixed seat 2 is open. A first sliding groove 4 is formed in the middle of the bottom plate 1. Second sliding grooves 5 are symmetrically formed on both sides of the bottom plate 1. The width between the second sliding grooves 5 is greater than the width of the vehicle. Door bodies 6 are symmetrically hinged inside the cover body 3 near the fixed seat 2. A stop block 7 is fixedly connected to the bottom plate 1 corresponding to the closing position of the door bodies 6. The stop block 7 is lower than the height of the vehicle chassis. A first slider 8 is slidably connected to the second sliding groove 5 corresponding to the door bodies 6. A connecting rod 9 is hinged to the first slider 8. One end of the connecting rod 9 is hinged to the door body 6. A sliding plate 27 is slidably connected to the first sliding groove 4. A front baffle 10 is fixedly connected to the sliding plate 27. The front baffle 10 corresponds to the front of the vehicle head. A collision sensor 11 is fixedly connected to the front surface of the front baffle 10. Push plates 12 are symmetrically and fixedly connected to both sides of the sliding plate 27. The push plates 12 extend into the second sliding groove 5. A long slot for the movement of the push plates 12 is provided between the second sliding groove 5 and the first sliding groove 4.

[0025] During the collision test of the door body 6, the vehicle can push the sliding plate 27 through the front baffle 10, thereby pushing the first slider 8 through the push plates 12. Then the first slider 8 pulls the door body 6 to close through the connecting rod 9 until the door body 6 fits with the stop block 7 to form a limit, so as to isolate the rear area of the cover body 3, and cooperate with the cover body 3 to isolate the outside, so as to control the range of debris splashing during the collision between the door body 6 and the cover body 3, effectively reducing the splashing range and facilitating subsequent cleaning.

[0026] A second slider 13 is slidably connected to the front side of the push plate 12 in the second sliding groove 5. A guide rod 14 is fixedly connected to the second slider 13. The tail end of the guide rod 14 slidably penetrates through the push plate 12. A round hole for the guide rod 14 to slide through is formed at the end of the push rod 12.

[0027] A stop piece 15 is fixedly connected to the tail end of the guide rod 14. The stop piece 15 is provided to prevent the guide rod 14 from slipping off the push plate 12. A spring 16 is sleeved on the outside of the guide rod 14. The spring 16 is arranged between the second slider 13 and the push plate 12.

[0028] By cooperating with the spring 16, a second slider 13 is installed on the front side of the push plate 12 through the guide rod 14, so that the push plate 13 can elastically push the first slider 8 through the second slider 13. When the push plate 12 drives the door body 6 to form a closed effect through the stop block 7, the sliding plate 27 can continue to slide, avoiding affecting the collision.

[0029] The fixed seat 2 is provided with an installation cavity 17. A partition plate 18 is fixedly connected inside the installation cavity 17. A rotating seat 19 is rotatably connected to the partition plate 18. A motor 20 is fixedly installed on the bottom surface of the partition plate 18. The output end of the motor 20 rotatably penetrates through the partition plate 18 and is fixedly connected to the rotating seat 19.

[0030] The top surface of the rotating seat 19 is fixedly connected with an intermediate platform 21.

[0031] On one side of the intermediate platform 21, first fixing rods 22 are symmetrically and fixedly connected. The ends of the first fixing rods 22 are jointly fixedly connected with an impact plate 23. On the other side of the intermediate platform 21, second fixing rods 24 are symmetrically and fixedly connected. The ends of the second fixing rods 24 are jointly fixedly connected with an impact column 25.

[0032] The motor 20 can drive the rotating seat 19 to rotate, thereby switching the impact column 25 and the impact plate 23, so as to facilitate the impact test with different impact objects.

[0033] The cover body 3 is provided with an inlet and outlet corresponding to the side of the fixed seat 2. A sealing door 26 is provided at the inlet and outlet. One side of the sealing door 26 is hinged to the cover body 3, and a door lock is provided between the other side of the sealing door 26 and the cover body 3.

[0034] The inlet and outlet are blocked by the sealing door 26, so that the inlet and outlet can be opened after the collision test, facilitating the entry of personnel.

[0035] The collision sensor 11 and the motor 20 are both electrically connected to an external controller and a power supply.

[0036] The working principle of the present utility model is as follows:

[0037] During use, the vehicle drives onto the bottom plate 1. At this time, the front baffle 10 is brought close to the head of the vehicle. The motor 20 drives the rotating seat 19 to rotate to switch the impact plate 23 or the impact column 25 for corresponding impact tests. At this time, the vehicle starts for the impact test. During the forward movement of the vehicle, the front baffle 10 drives the sliding plate 27 to slide, and the sliding plate 27 drives the push plate 12 to move synchronously. The push plate 12 drives the second slider 13 to approach the first slider 8 through the cooperation of the spring 16 and the guide rod 14. Thus, the second slider 13 pushes the first slider 8, and the first slider 8 drives the door body 6 to close through the connecting rod 9 until the door body 6 approaches the stop block 7, thereby completing the closing operation. During this process, the vehicle continues to move forward until it impacts the corresponding impact plate 23 or impact column 25. At this time, the push plate 12 can continue to move forward by squeezing the spring 16. During the impact, the collision force can be monitored by the collision sensor 11. After the collision is completed, the sealing door 26 is opened, and the isolation area formed by the door body 6 and the cover body 3 is entered for observation and cleaning.

[0038] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
