[0026] The following is a further description of the method of use of the present invention in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 3 As shown, a variable elastic anti-collision bracket includes an anti-collision plate 1 for track anti-collision, and also includes: a hinge assembly 2;

[0028] The hinge assembly 2 comprises:

[0029] A plurality of hinge pieces 21 are connected to form a polygon, wherein one of the hinge pieces 21 is connected to the anti-collision plate 1, and a fixing seat is connected to the hinge piece 21 on the side of the hinge assembly 2 away from the anti-collision plate 1 and fixed to the ground; the fixing seat is fixed to the ground by expansion bolts, thereby fixing the entire anti-collision plate 1 to the ground.

[0030] The elastic material 3 is arranged inside the polygon formed by the plurality of hinge pieces 21 connected to each other, and is used to absorb the impact force generated by the collision and provide buffering.

[0031] According to the track conditions, corresponding elastic material 3 is selected and placed inside the hinge assembly 2 .

[0032] The hinge plate 21 is a rectangular structure, and a plurality of openings 24 are provided in a linear array at a midline position of the hinge plate 21 . The hinge plate 21 is connected to the anti-collision plate 1 by bolts passing through the openings 24 .

[0033] The adjacent hinge pieces 21 are rotatably connected via the positioning pins 4. The hinge pieces 21 are connected via the positioning pins 4, so that each hinge piece 21 can rotate when it is hit, thereby providing a buffer.

[0034] The elastic material 3 is a prism. The prism matches the hinge piece 21, and the number of hinge pieces 21 is the same as the number of faces of the prism, so that the hinge piece 21 can completely wrap the prism, and a multi-faceted prism can be made according to the actual situation of the track.

[0035] The anti-collision plate 1 is a rectangular structure and is used to resist the impact of the racing car.

[0036] The anti-collision plate 1 is a PE plate.

[0037] The number of the hinge pieces 21 is greater than four. Because a prism is placed inside the hinge piece 21, and according to the actual situation of the track, the number of the hinge pieces 21 can be increased or decreased to form different polygons to absorb impact forces of different sizes.

[0038] The fixing seat comprises:

[0039] A plurality of connecting plates 22 are vertically connected to both sides of the hinge piece 21; and the connecting plates 22 and the hinge piece 21 can also be formed by bending a piece of sheet metal, which can improve its force strength and avoid damage caused by excessive impact.

[0040] The bottom plate 23 is disposed at the bottom of the connecting plate 22 and is used to fix the hinge assembly 2 on the ground. After the anti-collision plate 1 is hit, the anti-collision plate 1 will move backwards and cause the elastic material 3 inside the hinge assembly 2 to deform, thereby absorbing energy, while the hinge assembly 2 will not move due to the fixation of the fixing seat.

[0041] The connecting plate 22 is a triangular structure and is used to increase the connection strength between the hinge assembly 2 and the ground.

[0042] Working process: When the anti-collision plate 1 is hit, the anti-collision plate 1 will be subjected to a large impact force, and the anti-collision plate 1 will move backward. At the same time, the hinge assembly 2 and the elastic material 3 behind the anti-collision plate 1 will be deformed, and the hinge piece 21 on the hexagonal hinge assembly 2 will move, thereby absorbing the large impact force. After the impact is completed, the elastic material 3 will push the hinge piece 21 to move through its own elastic potential energy, and slowly return to its original state, thereby driving the anti-collision plate 1 to return to its original position.

[0043] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
