[0021] A dovetail slider is fixed to one side of the second vertical sliding column 12 close to the arc-shaped anti-collision plate 2, and a dovetail slide groove adapted to the dovetail slider is provided inside the arc-shaped anti-collision plate 2. The second vertical sliding column 12 and the arc-shaped anti-collision plate 2 are slidably connected through the cooperation of the dovetail slider and the dovetail slide groove. Through the arrangement of the dovetail slider and the dovetail slide groove, the second vertical sliding column 12 can slide on the outer side of the arc-shaped anti-collision plate 2.

[0022] The buffer assembly includes two first rectangular connecting blocks 3, both ends of the first rectangular connecting blocks 3 are rotatably connected with oblique rotating columns 5, and a second rectangular moving block 4 is rotatably connected between the two oblique rotating columns 5 at the same end through a pin shaft, one of the first rectangular connecting blocks 3 is close to one side of the arc-shaped anti-collision plate 2 and is fixedly connected to the arc-shaped anti-collision plate 2, and a vertical light rod 8 is slidably connected inside the other first rectangular connecting block 3, and the vertical light rod 8 is close to one side of the U-shaped frame 1 and is fixedly connected to the U-shaped frame 1, and a circular stopper 10 is fixed to the side of the vertical light rod 8 away from the U-shaped frame 1, and a first rigid spring 9 is arranged between the circular stopper 10 and the other first rectangular connecting block 3 and on the outside of the vertical light rod 8;

[0023] A circular through hole is provided inside the other first rectangular connecting block 3, and the vertical light rod 8 is located inside the circular through hole and is slidably connected with the other first rectangular connecting block 3 through the circular through hole. The circular through hole is provided so that the vertical light rod 8 can slide inside the first rectangular connecting block 3, and when the first rectangular connecting block 3 slides, the first rigid spring 9 is deformed by force;

[0024] When the arc-shaped anti-collision plate 2 is hit, the first rectangular connection block 3 can slide outside the vertical light rod 8 by setting the oblique rotating column 5. The sliding of the first rectangular connection block 3 causes the first rigid spring 9 to contract under force, thereby providing a buffering performance for the hit.

[0025] The pushing mechanism includes a vertical rotating plate 6, one end of the second rectangular moving block 4 is rotatably connected to the vertical rotating plate 6 through a pin shaft, the side of the vertical rotating plate 6 close to the U-shaped frame 1 is rotatably connected to a vertical connecting block 7, the vertical connecting block 7 is close to one side of the U-shaped frame 1 and is fixedly connected to the U-shaped frame 1, a vertical sliding piece 16 is fixed to one end of the second vertical sliding column 12 close to the first vertical sliding column 11, the vertical sliding piece 16 is located inside the first vertical sliding column 11 and is slidably connected to the first vertical sliding column 11, and a second rigid spring 13 is provided inside the first vertical sliding column 11 and inside the vertical sliding piece 16;

[0026] A transverse light rod 14 is fixed at both ends inside the U-shaped frame 1. The transverse light rod 14 passes through the interior of the first vertical sliding column 11 and is slidably connected to the first vertical sliding column 11. A third rigid spring 15 is provided at one end of the first vertical sliding column 11 and located on the outside of the transverse light rod 14.

[0027] When the arc-shaped anti-collision plate 2 is hit, the second rectangular moving block 4 allows the vertical rotating plate 6 to rotate with the connection between the vertical rotating plate 6 and the vertical connecting block 7 as the center of the circle. The rotation of the two vertical rotating plates 6 allows the first vertical sliding column 11 to slide on the outside of the horizontal light rod 14. The sliding of the first vertical sliding column 11 causes the third rigid spring 15 to deform under force, so that when the arc-shaped anti-collision plate 2 is hit longitudinally, the force can be converted into the horizontal movement of the first vertical sliding column 11, so as to better protect the frame.

[0028] When the arc-shaped anti-collision plate 2 is hit, the vertical sliding piece 16 can slide inside the first vertical sliding column 11, and the sliding of the vertical sliding piece 16 causes the second rigid spring 13 to be deformed, thereby improving the buffering performance of the arc-shaped anti-collision plate 2;

[0029] Designed to provide better cushioning performance and prevent damage to the frame, it can effectively convert the force of longitudinal impact into lateral force to reduce the driver's injuries.

[0030] Working principle: When the arc-shaped anti-collision plate 2 is hit, the first rectangular connection block 3 can slide outside the vertical light rod 8 through the setting of the oblique rotating column 5. The sliding of the first rectangular connection block 3 causes the first rigid spring 9 to contract under force, thereby providing a buffering performance for the hit;

[0031] When the arc-shaped anti-collision plate 2 is hit, the vertical sliding piece 16 can slide inside the first vertical sliding column 11, and the sliding of the vertical sliding piece 16 causes the second rigid spring 13 to be deformed, thereby improving the buffering performance of the arc-shaped anti-collision plate 2;

[0032] When the arc-shaped anti-collision plate 2 is hit, the second rectangular moving block 4 allows the vertical rotating plate 6 to rotate with the connection between the vertical rotating plate 6 and the vertical connecting block 7 as the center of the circle. The rotation of the two vertical rotating plates 6 allows the first vertical sliding column 11 to slide on the outside of the horizontal light rod 14. The sliding of the first vertical sliding column 11 causes the third rigid spring 15 to deform under force, thereby enabling the arc-shaped anti-collision plate 2 to be subjected to a longitudinal impact and convert it into a force for the horizontal movement of the first vertical sliding column 11, thereby better protecting the vehicle frame.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
