[0031] As Figures 5 to 7 shown, the clamping and bending assembly 4 is composed of a support frame 401, a third electric cylinder 402, a bending rod 403, a first sliding groove 404, a spring 405, a fixing plate 406, a first fixed joint plate 407, a guide rod 408, a slide bar 409, a connecting shaft 410, a connecting rod 411, and a first rotating shaft 412.

[0032] The clamping and bending assembly 4 is as follows: A support frame 401 is installed on the rotating seat 9. On one side of the support frame 401, a first rotating shaft 412 rotatably connected to the rotating seat 9 is provided. At the bottom of the first rotating shaft 412, a sliding rod 409 is provided, which is swing-connected to the arc-shaped sliding hole 15 of the rotating seat 9 along the arc direction. A third electric cylinder 402 is fixedly installed on the support frame 401. The output shaft of the third electric cylinder 402 is fixedly connected to a connecting shaft 410. Two connecting rods 411 are rotatably installed on the connecting shaft 410. The two connecting rods 411 are symmetric with each other with the perpendicular bisector of the connecting shaft 410 as the symmetry line. Two bending rods 403 are rotatably installed on the support frame 401. The two bending rods 403 are symmetric with each other with the symmetry line of the support frame 401 as the perpendicular line. One end of each connecting rod 411 is respectively rotatably connected to the bending rod 403 on the corresponding side. A first sliding groove 404 is respectively machined on each bending rod 403.

[0034] The working principle of this embodiment is as follows: Place the spoiler 10 on the two fixing plates 406. The second fixed joint plates 14 at both ends of the bottom of the spoiler 10 and the first fixed joint plates 407 of the fixing plates 406 are fixedly connected by bolts. Under the action of the spring 405, the two fixing plates 406 slide on the corresponding first sliding grooves 404 and guide rods 408 respectively, and the distance between the two fixing plates 406 can be easily adjusted according to the size of the spoiler 10. The clamping and bending assembly 4 bends the spoiler 10. Through the high-speed camera and optical measurement technology in the prior art, the surface deformation of the spoiler 10 is monitored in real time to test the deformation situation and the ability to resist damage of the spoiler 10 in the bent state, so as to detect the toughness of the spoiler 10.

[0035] The output end of the second electric cylinder 2 drives the support plate 12 to slide horizontally along the second chute 13 at the top of the fixed frame 3, facilitating the adjustment of the positions of the multiple first electric cylinders 1 on the support plate 12 in the horizontal direction. The output end of each first electric cylinder 1 drives the striking hammer 11 to move vertically. When the spoiler 10 is directly below the multiple striking hammers 11, the multiple striking hammers 11 or a single striking hammer 11 can strike the corresponding position of the spoiler 10. When the spoiler 10 rotates or swings, the corresponding single striking hammer 11 can strike the position of the spoiler 10, which is used to test the toughness of the spoiler 10 in the bent state.

[0036] When simulating the driving of a vehicle on an uphill or downhill slope to detect the toughness of the spoiler 10, the output shaft of the second motor 6 drives the second rotating shaft 22 to rotate. The second rotating shaft 22 drives the two first gears 23 to rotate. Each first gear 23 drives the swinging housing 8 to swing through meshing transmission with the arc-shaped rack 20. The swinging housing 8 drives the spoiler 10 to swing through the rotating seat 9 and the clamping and bending assembly 4 in sequence, simulating the uphill and downhill states of the vehicle.

[0037] When simulating the driving of a vehicle on a side slope to detect the toughness of the spoiler 10, the output shaft of the first motor 5 drives the lead screw 17 to rotate. The sliding block 26 slides horizontally along the lead screw 17. The sliding rod 409 slides vertically in the vertical sliding hole 16 of the sliding block 26. At the same time, the sliding rod 409 slides along the arc direction in the arc-shaped sliding hole 15 on one side of the rotating seat 9. The sliding rod 409 drives the entire clamping and bending assembly 4 and the spoiler 10 to move, which is used to simulate the side slope state of the vehicle.

[0038] When simulating the driving of a vehicle in a turning state to detect the toughness of the spoiler 10, the output shaft of the third motor 19 drives the second gear 24 to rotate. The second gear 24 drives the third gear 25 to rotate through meshing transmission. The third gear 25 drives the rotating seat 9 to rotate. The rotating seat 9 drives the spoiler 10 on the clamping and bending assembly 4 to rotate by a certain angle, which is used to simulate the turning state of the vehicle.

[0039] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
