[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] like Figures 1 to 4 A vehicle noise detection platform includes a detection platform 1 with a concave center. An anti-collision mechanism is provided in the concave area. The anti-collision mechanism includes an electric telescopic rod 9, a connecting rod 10, anti-collision tubes 11, and a shock-absorbing ring 12. The connecting rod 10 has electric telescopic rods 9 at both ends. The connecting rod 10 is perpendicular to the ground, and anti-collision tubes 11 are evenly spaced. The anti-collision tubes 11 are fitted with shock-absorbing rings 12. Vibration simulation mechanisms are provided at the four corners of the detection platform. These vibration simulation mechanisms include a vibrator 2, a lifting rod 3, a support plate 4, a telescopic device 5, and a limiting plate 6. The vibrator 2 has a lifting rod 3 at its upper end, and a support plate 4 at its upper end. Both sides of the support plate 4 abut against one end of the limiting plate 6, with the abutting surfaces fitting together. The other end of the limiting plate 6 is connected to the telescopic device 5. The inward retraction distance of the limiting plate 6 is set to the distance between the vertical surface of the limiting plate and the vertical surfaces of the front guide ramp 7, the detection platform 1, and the rear guide ramp 8. The telescopic device 5 drives the limiting plate 6 to retract inward, and the lifting rod 3 drives the support plate 4 to descend to the end of the limiting plate 6 to form a groove to facilitate the vehicle to be stabilized in the corresponding position.
[0017] The testing platform 1 is equipped with a front ramp 7 and a rear ramp 8 to facilitate vehicles entering and exiting the testing platform.
[0018] The end of the anti-collision tube 11 is equipped with a buffer pad.
[0019] The support plate 4 is in the shape of an inverted trapezoid. The left and right sides of the support plate 4 are provided with inclined surfaces that gradually narrow from wide to narrow. The upper surface is concave inward to form a limiting groove.
[0020] The center of the support plate 4 has a driving mark to clearly indicate the vehicle's stopping position.
[0021] The limiting plate 6 is a right-angled trapezoid, and the inclined surface of the limiting plate 6 matches the inclined surface of the support plate 4.
[0022] In operation, the vehicle travels from the front ramp 7 to the marked position on the testing platform 1. The telescopic device controls the limit plate 6 to retract inward, and the lifting rod 3 to descend, stabilizing the vehicle within the limit groove. Maintenance personnel can then inspect the vehicle's exterior. Next, the lifting rod 3 is activated to lift the vehicle, and the electric telescopic rod 9 raises the anti-collision mechanism. The vibrator 2 is activated, causing the support plate 4 to vibrate, simulating the shaking that occurs when a vehicle is in motion. Adjusting the vibrator 2 to different intensities simulates different driving conditions, facilitating the maintenance personnel's investigation of the specific cause of abnormal vehicle noises. After inspection, the vibrator 2 is stopped, the anti-collision mechanism and vibration simulation mechanism return to their original positions, and the vehicle drives away from the rear ramp 8.
