It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a motor vehicle braking performance detection device, including a bearing plate 1 and a moving plate 2, a mounting groove 22 is provided at the bottom of the moving plate 2 near the front side, an axial hole 21 is symmetrically provided at the top of the moving plate 2, a rotating shaft 3 is rotatably provided inside the two axial holes 21, a second motor 31 is embedded inside the mounting groove 22, an output end of the second motor 31 is fixedly connected to one of the rotating shafts 3, the tops of the two rotating shafts 3 are fixedly connected to a rotating plate 32, a U-shaped frame 35 is fixedly installed on the top of the rotating plate 32, a hydraulic push rod 36 is fixedly installed on the inner top of the U-shaped frame 35, the telescopic end of the hydraulic push rod 36 slides through the inner top of the U-shaped frame 35 and extends to the top, and the hydraulic push rod 31 is embedded inside the mounting groove 22, and the output end of the second motor 31 is fixedly connected to one of the rotating shafts 3, and the tops of the two rotating shafts 3 are fixedly connected to the rotating plate 32, a U-shaped frame 35 is fixedly installed on the top of the rotating plate 32, a hydraulic push rod 36 is fixedly installed on the inner top of the U-shaped frame 35, and the telescopic end of the hydraulic push rod 36 slides through the inner top of the U-shaped frame 35 and extends to the top, and the hydraulic push rod 31 is embedded inside the mounting groove 22. A support plate 37 is fixedly installed on the telescopic end of 6, and connecting shafts 33 are symmetrically fixedly installed on the tops of the two rotating plates 32 near the edges. The four connecting shafts 33 are distributed in two groups on the left and right, and connecting rods 34 are rotatably arranged between the outer surfaces of the two groups of connecting shafts 33. A detection roller 11 is arranged on the top of the load-bearing plate 1 near the front side, and slopes 12 are arranged on the outer surfaces of the front and rear sides of the load-bearing plate 1. Rectangular grooves 13 are symmetrically opened near the middle of the top of the load-bearing plate 1, and the rectangular grooves 13 cooperate with the support plate 37. A groove 14 is opened at the bottom of the load-bearing plate 1, and a limit rod 38 is symmetrically fixedly installed on the bottom of the support plate 37. The outer surface of the limit rod 38 slides through the top of the U-shaped frame 35 and extends to the bottom.
[0024] The effect achieved by the entire embodiment 1 is that the motor vehicle is driven onto the load-bearing plate 1, and the support plate 37 is driven to move upward by starting the hydraulic push rod 36, so that the chassis of the motor vehicle can be supported and suspended, and one of the support plates 37 can be driven to rotate by starting the second motor 31, and the two rotating plates 32 can be rotated with the two rotating shafts 3 as the axis by cooperating with the connecting rod 34.

[0026] The effect achieved by the entire embodiment 2 is that by starting the first motor 25 to drive the threaded rod 26 to rotate, the movable plate 2 can be moved forward or backward, thereby adjusting the front and rear positions of the motor vehicle, ensuring that the wheels are exactly in the position between the supporting plates 1, and further improving the braking detection conditions of the motor vehicle. When the movable plate 2 moves, the slider 23 slides in the slide groove 15, which plays a role in guiding and limiting the movable plate 2.
[0027] Working principle: When in use, drive the motor vehicle onto the supporting plate 1, and drive the supporting plate 37 to move upward by starting the hydraulic push rod 36, and support the chassis of the motor vehicle so that the motor vehicle is suspended in the air. Then, one of the supporting plates 37 can be driven to rotate by starting the second motor 31, and the two supporting plates 37 can be rotated synchronously with the connecting rod 34. When the two supporting plates 37 rotate, the angle of the motor vehicle can be fine-tuned, thereby ensuring the verticality of the tire of the motor vehicle and the detection roller 11, providing reliable and objective detection conditions for the braking performance of the motor vehicle. By starting the first motor 25 to drive the threaded rod 26 to rotate, the movable plate 2 can be moved forward or backward, which adjusts the front and rear positions of the motor vehicle, ensures that the wheels are exactly in the position between the supporting plates 1, and further improves the detection conditions of the braking performance of the motor vehicle.
