After the car is driven onto the table top of the test bench, the hydraulic lifting column can be extended to drive the load-bearing plate, the support plate and the rotating roller to move upward, so that the wheel is lifted and supported by the cooperation between two adjacent rotating rollers, so that the car can be accelerated in the air. After accelerating to a certain speed, the hydraulic lifting column is retracted, and the rotating roller is lowered below the test bench, and the car tire is fitted with the test bench table, so as to simulate the car under high-speed driving state to perform a simulated collision experiment, which effectively solves the problem that the automobile safety collision test equipment in the prior art cannot effectively simulate the vehicle collision situation under high-speed driving state, resulting in the lack of comprehensiveness and accuracy of the detection data. Its specific technical scheme is as follows:

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0024] A high-speed automobile collision detection device comprises a test bench 1, a ramp plate 11 is fixedly installed on the right surface of the test bench 1, a wall 12 is fixedly installed on the left side of the upper surface of the test bench 1, four through holes 13 are opened on the upper surface of the test bench 1, a hydraulic lifting column 2 is fixedly installed in the test bench 1, a load-bearing plate 21 is fixedly installed on the upper surface of the hydraulic lifting column 2, eight support plates 22 are symmetrically fixedly installed on the upper surface of the load-bearing plate 21, weighing bearings are embedded in the support plates 22, a follower roller 23 is rotatably installed between two corresponding weighing bearings, and the support plates 22 are located directly below the corresponding through holes 13;
[0025] During the actual test, the hydraulic lifting column 2 is first extended to drive the rotating roller 23 to move up to expose the surface of the test bench 1, and then the vehicle is driven onto the test bench 1 through the ramp 11, and the tires of the car are driven between two adjacent rotating rollers 23. Subsequently, the hydraulic lifting column 2 is used again to move the rotating roller 23 up to make the tires of the car empty. Then, the unmanned driving technology during the car collision is used to increase the vehicle speed to the speed to be tested. Finally, the hydraulic lifting column 2 is retracted to mobilize the rotating roller 23 to move down under the surface of the test bench 1. At this time, the car tire contacts the surface of the test bench 1, thereby moving at high speed to rush towards the wall 12 to complete the high-speed collision detection experiment. Compared with the existing technology, the equipment can simulate the collision of vehicles under different driving speeds, and the detected experimental data is more comprehensive and accurate.
[0026] Since the follower roller 23 rotates at high speed with the tire during the acceleration of the car, the weighing bearing is prone to generate a high temperature. In order to reduce the damage caused by high temperature to the weighing bearing, the following method is combined with Figure 1 and Figure 4 As shown, two water tanks 3 are symmetrically installed in the experimental table 1, and water pumps 4 are fixedly installed on the outer surfaces of the water tanks 3. A water suction pipe 41 is installed between the water inlet end of the water pump 4 and the corresponding water tank 3, and a water supply pipe 42 is installed at the drainage end of the water suction pipe 41. The water supply pipe 42 is L-shaped, and the drainage end of the water supply pipe 42 is fixedly connected with a water spray pipe 43, and two atomizing nozzles 431 are fixedly installed on the outer surface of the water spray pipe 43. The spraying position of the atomizing nozzle 431 corresponds to the position of the weighing bearing. The water pump 4 can be used to supply the cooling water in the water tank 3 to the atomizing nozzle 431 through the water suction pipe 41, the water supply pipe 42 and the water spray pipe 43, so as to water-cool the weighing bearing at the corresponding position, thereby reducing the damage caused by the high-speed rotation of the weighing bearing and extending its service life.
[0027] In addition, in order to prevent the cooling water sprayed by the atomizing nozzle 431 from splashing onto the driving area of the vehicle and affecting the friction between the vehicle and the test bench 1, the accuracy of the test data can be ensured. Figure 1 As shown, two shielding frames 5 are symmetrically fixedly installed on the upper surface of the test bench 1, and the water spray pipe 43 is fixedly installed in the corresponding shielding frame 5. The lower surface of the shielding frame 5 is provided with two embedding openings. When the rotating roller 23 is used to lift the automobile tire, the top of the support plate 22 is located in the corresponding embedding opening, and the load-bearing bearing is located in the corresponding shielding frame 5. The shielding frames 5 can be used to control the spray range of the atomizing nozzle 431, so as to avoid water splashing to the automobile driving area and ensure the accuracy of the detection data.
[0028] In addition, in order to facilitate the collection of the sprayed cooling water, Figure 4 As shown, two water flow grooves 14 with slopes are symmetrically opened on the upper surface of the experimental table 1, and the shielding frame 5 is set in the corresponding water flow grooves 14 to seal the water flow grooves 14. Drain outlets 15 are opened through the water flow grooves 14, and water inlets 31 are opened on the upper surface of the water tank 3. The water inlet 31 is connected with the corresponding drain outlet 15. After the sprayed cooling water contacts the load-bearing bearing, it will flow toward the drain outlet 15 under the action of the water flow grooves 14, and finally flow into the water tank 3 for recycling and reuse.
[0029] Here, it is necessary to explain the above water recycling. During the automobile testing process, since the acceleration time of the automobile is usually no more than fifteen seconds, the continuous cooling time of the symmetrical weight bearing will also be no more than fifteen seconds. In addition, considering that a long interval is required between two automobile high-speed collision tests, the used water can be simply recycled into the water tank 3 and allowed to cool itself for the next use. Therefore, it is not necessary to set up a special cooling device for the water tank 3.
[0030] To prevent impurities from entering the water tank 3, Figure 4 As shown, Figure 4 As shown, a filter plate 151 is embedded and installed at the opening of the drain port 15. The filter plate 151 can effectively filter large particles of impurities from the outside to prevent them from falling into the water tank 3 and being used as cooling medium, thereby affecting the service life of the weighing bearing.
[0031] In order to ensure that the load-bearing plate 21, the support plate 22 and the rotating roller 23 can move vertically up and down, so as to accurately lift the tire of the car, Figure 4 As shown, four bushings 25 are fixedly installed in the test bench 1, and four directional rods 24 are fixedly installed on the lower surface of the load-bearing plate 21. The directional rods 24 are slidably installed in the bushings 25. Under the action of the directional rods 24 and the bushings 25, the load-bearing plate 21, the support plate 22 and the rotating roller 23 can be ensured to move vertically up and down, so as to accurately lift the automobile tires.
[0032] Finally, when the car collides with the wall 12, to ensure that the broken debris will not be scattered everywhere, such as Figure 1 As shown, two side protection plates 6 are fixedly installed on the upper surface of the experimental table 1, and the rear ends of the side protection plates 6 are in contact with the front surface of the wall 12. Through their blocking effect, the broken residues can be confined to a specific range, thereby greatly facilitating the cleaning and collection of the residues.
