The coordinated use of the buffer component 10 and the rubber protective plate 3 is convenient for playing a protective role during the test drive of the autonomous driving vehicle. During operation, the staff uses the equipment to splice into a test drive runway for the autonomous driving vehicle to test drive the autonomous vehicle. Through the coordination of the rubber protective plate 3 and the arc component, hard contact between the vehicle and the fence is avoided when the autonomous driving vehicle collides with the fence. When the driving vehicle collides with the rubber protective plate 3, the impact force generated on the rubber protective plate 3 will be transmitted to the buffer component 10, and then the connecting column 15 compresses the second spring 16 to move toward the inside of the limiting sleeve 14, so that the elastic potential energy of the second spring 16 offsets the impact force of the vehicle, further reducing the damage to the driving vehicle.
[0025] The working principle of the anti-collision fence for autonomous driving vehicles provided by the present invention is as follows:
[0026] When operating this type of anti-collision fence for autonomous vehicles, the staff uses equipment to splice into a test drive track for autonomous vehicles to test drive the autonomous vehicles. By cooperating with the rubber protective plate 3 and the arc component, hard contact between the vehicle and the fence is avoided when the autonomous vehicle collides with the fence. When the driving vehicle collides with the rubber protective plate 3, the impact force generated on the rubber protective plate 3 will be transmitted to the buffer component 10, and then the connecting column 15 compresses the second spring 16 to move into the limiting sleeve 14, so that the elastic potential energy of the second spring 16 impacts the vehicle. The force can be offset to further reduce the damage to the driving vehicle. By setting the slide groove 13, the slider 11 and the first spring 12 for coordinated use, the impact force on the rubber protective plate 3 can be offset for the second time. When the rubber protective plate 3 is hit, the impact force will be transmitted to the first vertical plate 2 and the second vertical plate 5 through the connecting plate 7. Then, the first vertical plate 2 and the second vertical plate 5 slide in the slide groove 13 through the slider 11, and then the first spring 12 is compressed, so that the elastic potential energy of the first spring 12 can offset the impact force of the vehicle, so as to protect the vehicle for the second time.
[0027] Compared with the related art, the anti-collision fence for autonomous driving vehicles provided by the present invention has the following beneficial effects:

During operation, the staff splices the equipment into a test drive track for the autonomous driving vehicle to test drive the autonomous vehicle. The rubber protective plate 3 cooperates with the arc component to avoid hard contact between the vehicle and the fence when the autonomous driving vehicle collides with the fence. When the driving vehicle collides with the rubber protective plate 3, the impact force generated on the rubber protective plate 3 will be transmitted to the buffer component 10, and then the connecting column 15 compresses the second The spring 16 moves toward the inside of the limiting sleeve 14, so that the elastic potential energy of the second spring 16 offsets the impact force of the vehicle, further reducing the damage to the driving vehicle. By setting the slide groove 13, the slider 11, and the first spring 12 for coordinated use, it is convenient to offset the impact force received by the rubber protective plate 3 for a second time, so that when the rubber protective plate 3 is subjected to an impact force, the impact force will be transmitted to the first vertical plate 2 and the second vertical plate 5 through the connecting plate 7, and then the first vertical plate 2 and the second vertical plate 5 slide in the slide groove 13 through the slider 11, and then compress the first spring 12, so that the elastic potential energy of the first spring 12 offsets the impact force of the vehicle, so as to facilitate secondary protection of the vehicle.
