[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown in the figure, a vibration reduction and noise reduction protection structure for an automobile acceleration trolley test system according to an embodiment of the present invention includes an acceleration trolley body 1. A protective mechanism is provided on the top of the acceleration trolley body 1. The protective mechanism includes: an anti-collision component, including a pair of concave frames 2 fixedly connected to the top of the acceleration trolley body 1, symmetrically distributed on the left and right sides of the base plate, a pair of fixed rods 3 fixedly connected between opposite side walls of the concave frames 2, sliding blocks 4 slidably connected to the fixed rods 3, and an anti-collision plate 5 fixedly connected between opposite side walls of a set of sliding blocks 4, vertically arranged at the front end of the acceleration trolley body 1, facing the direction of trolley movement, and is the direct force-bearing component of the collision. The material is high-strength Q235 steel plate to resist impact. A vibration reduction component is provided on the acceleration trolley body 1 to support the anti-collision plate 5; and a noise reduction component is provided on the acceleration trolley body 1 to reduce noise.

[0018] The shock absorption assembly includes an acceleration platform body 1 with a pair of fixed columns 6 fixed to the top, a support plate 7 fixed to the top of the pair of fixed columns 6, and a horizontal plate located at the top of the fixed columns 6 for mounting a concave block 8 and a first threaded rod 10, providing an upper mounting platform for the shock absorption assembly. The top of the support plate 7 has a concave block 8 fixed to it, and the bottom of the concave block 8 has a first motor 9 fixed to it horizontally. The output end of the first motor 9 is provided with a first threaded rod 10, and the bottom of the first threaded rod 10 is rotatably connected to the top of the support plate 7, and the bottom of the first threaded rod 10 penetrates the bottom of the support plate 7.

[0019] A sliding plate 11 is threaded onto the first threaded rod 10. A hydraulic buffer 12 is fixed to the side wall of the sliding plate 11. It is horizontally arranged with its telescopic end facing the anti-collision plate 5. It is a core shock-absorbing component that absorbs the impact force of the collision through internal damping oil and attenuates the collision force of the trolley. A square block 13 is fixed to the telescopic end of the hydraulic buffer 12.

[0020] The side wall of the anti-collision plate 5 has a pair of rectangular grooves 14. A guide rod 15 is fixed between the opposite side walls of the rectangular grooves 14. The square block 13 is slidably connected to the guide rod 15 through a sliding hole, and can slide smoothly along the guide rod 15 to avoid the square block 13 from shifting. The square block 13 is slidably connected in the rectangular groove 14.

[0021] During operation, the first motor 9 is activated based on the height of the trolley and the position of the test piece. The output of the first motor 9 drives the first threaded rod 10 to rotate, and the sliding plate 11 rises or falls along the threaded rod until the height of the hydraulic buffer 12 is aligned with the center of gravity of the trolley, thus providing protection. Furthermore, the protective center of gravity can be adjusted according to the impact position of different vehicle models. This solves the problem in the existing technology where the vehicle acceleration test system may experience a forward collision during operation. Due to the lack of a targeted and effective protective structure, the existing system is prone to damage to the vehicle body, with parts flying everywhere, posing a safety risk to the workers.

[0022] The noise reduction component includes a pair of sliding grooves 16 on each side of the accelerator body 1. Sliding rails 17 are slidably connected in the sliding grooves 16. Protective chambers 18 are fixed on the pair of sliding rails 17. The semi-enclosed cover is U-shaped and covers the accelerator body 1. The left and right sides are fixed to the sliding rails 17, and the top covers the width of the accelerator body 1. During the test, it can completely cover the trolley and block the spread of noise. The inner wall of the protective chamber 18 is provided with sound-absorbing panels 19. The material is porous polyester fiber with a thickness of 5-8mm. It absorbs sound wave energy through the pores and converts noise into heat energy, thereby reducing environmental noise.

[0023] An upright plate 20 is fixedly attached to the top of the accelerator body 1. A second threaded rod 21 is rotatably connected to the upright plate 20 through a rotating hole. A rectangular block 22 is fixedly attached to the top of the protective chamber 18. The rectangular block 22 is threadedly connected to the second threaded rod 21 through a threaded hole. An L-shaped block 23 is fixedly attached to the side wall of the upright plate 20. A second motor 24 is fixedly attached to the vertical side wall of the L-shaped block 23. The output end of the second motor 24 is drivenly connected to the second threaded rod 21.

[0024] During operation, the acceleration chamber can be moved, allowing staff to move the car to the corresponding position and leaving space for testing. The sound-absorbing panel 19 can absorb the sound waves generated during the acceleration testing process, improving the environment and protecting the hearing of personnel.

[0025] Working principle: Based on the height of the trolley and the position of the test piece, until the height of the hydraulic buffer 12 is aligned with the center of gravity of the trolley, the first motor 9 is started. The output end of the first motor 9 drives the first threaded rod 10 to rotate. The first motor 9 drives the first threaded rod 10 to rotate, and the sliding plate 11 moves up and down along the threaded rod through the thread transmission, thereby adjusting the height of the hydraulic buffer 12. The hydraulic buffer 12 cooperates with the rectangular groove 14 of the anti-collision plate 5 through the square block 13 at the telescopic end. The square block 13 can slide laterally along the guide rod 15 in the rectangular groove 14. When the anti-collision plate 5 is moved by a collision, the hydraulic buffer 12 absorbs the impact force through the damping effect of the telescopic end. At the same time, the guide rod 15 restricts the movement direction of the square block 13 to ensure accurate transmission of the buffering force.

[0026] Before the test begins, the second motor 24 is started. The output end of the second motor 24 drives the second threaded rod 21 to rotate. The rectangular block 22 moves along the second threaded rod 21, which drives the protective chamber 18 to move synchronously. The sliding rail 17 slides along the sliding groove 16 until the protective chamber 18 completely covers the car.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
