[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0021] like Figure 1 , 2 As shown in Figure 3, a bow-shaped plate and elliptical rotor combined guardrail includes a plurality of fixed columns 1, with bow-shaped plates 3 connected between adjacent fixed columns 1, a plurality of mounting grooves 4 provided on the bow-shaped plates 3, a plurality of elliptical rotors 5 that rotate with external force collision are evenly installed in each mounting groove 4, and when the elliptical rotor 5 is rotated by external force, its major and minor axes can intermittently rub against the inner wall of the mounting groove 4 to buffer the external collision contact force.

[0022] The elliptical rotor 5 is located in the arch plate, made of polymer elastic material, and has an ellipsoidal shape. The major axis diameter is 300mm, the minor axis diameter is 250-270mm, the spacing between adjacent elliptical rotors 5 can be set to 50mm, and the outer edge is coated with reflective material. In the event of a collision, the elliptical rotor can rotate and the major axis section intermittently rubs to effectively disperse and absorb the impact force to the greatest extent, reducing damage to vehicles and pedestrians.

[0023] The arched plate 3 is made of high-strength, lightweight alloy material and processed into an arched structure. The length can be made into three specifications of 4320mm, 8320mm, and 12320mm. Two transverse holes are opened at both ends of the arched plate 3 to facilitate overlapping and fixing of the plates.

[0024] like Figure 5 As shown, the transverse cross section of the elliptical rotor 5 is elliptical, and the elliptical major axis section of the elliptical rotor 5 is in the same horizontal direction as the arch plate 3, so that the installation of the elliptical rotor 5 is more convenient and quick.

[0025] There is a rotation gap between the side wall of the short axis section of the elliptical rotor 5 and the inner wall of the installation groove 4 , and a force-bearing deformation portion 9 is generated when the side wall of the long axis section of the elliptical rotor 5 contacts the inner wall of the installation groove 4 .

[0026] The outer sides of the upper and lower ends of the elliptical rotor 5 are provided with bevels 6 matching the inner shape of the mounting groove 4 .

[0027] The center of the elliptical rotor 5 is rotationally connected to the plug-in shaft rod 7 vertically installed on the arch plate 3. The plug-in shaft rod 7 passes through multiple installation grooves 4 from the upper part of the arch plate 3 and is fixed with a fixing nut 8. The plug-in shaft rod 7 is made of high-strength, lightweight alloy material and has high resistance to deformation, ensuring that it remains in its original state in the event of a collision, which is convenient for maintenance and disassembly.

[0028] Protective gaskets are provided at the upper and lower ends of the elliptical rotor 5, which are inserted into the inserted shaft rod 7. High-density fabric or rubber gaskets are placed at the contact position between the arch plate 3 and the elliptical rotor 5. Both sides have large friction and are used to protect the anti-corrosion layer of the arch plate 3 and stabilize the rotation of the elliptical rotor 5, making it difficult to rotate when it is not directly subjected to force.

[0029] like Figure 4 As shown, the rear ends of both sides of the arch plate 3 are fixedly connected to the fixed columns 1 through multiple anti-obstruction blocks 2. The anti-obstruction blocks 2 are made of high-strength, lightweight alloy material and are processed into a hexagonal structure, which improves the energy absorption capacity of the guardrail.

[0030] The outside of the elliptical rotor 5 is coated with a reflective coating to enhance the warning effect.

[0031] The implementation principle of the bow plate elliptical rotor combined guardrail in the embodiment of the present application is:

[0032] When a car on the road collides with the side guardrail, the car body will first contact the elliptical rotor 5 inside the mounting groove 4 of the arch plate 3, driving the elliptical rotor 5 to rotate (when there is no collision, the long axis section of the elliptical rotor 5 is parallel to the arch plate 3, that is, attached to the arch plate 3). Figure 5When the elliptical rotor 5 rotates, its long axis section marked as A moves toward the inside of the installation slot 4, while the short axis section marked as B moves toward the outside of the installation slot 4. The initial rotation of the elliptical rotor 5 forms a buffer for the colliding vehicle. When the elliptical long axis section of the elliptical rotor 5 contacts and rubs against the inner wall of the installation slot 4 (see Figure 2), the elliptical rotor 5 rotates, and the long axis section of the elliptical rotor 5 moves toward the inside of the installation slot 4. Figure 5 In the state diagram marked as b and c), the stress-deformed portion 9 of the long axis section of the elliptical rotor 5 is squeezed and deformed by the inner side of the mounting groove 4 to form a large friction buffer force, so that the elliptical rotor 5 and the colliding vehicle rotate relative to each other, which can greatly reduce the speed of the vehicle, and has a good effect of absorbing energy and reducing the speed of the spraying vehicle, thereby greatly protecting the safety of the colliding vehicle;

[0033] Moreover, the mounting groove 4 of the arch plate 3 also supports and protects the elliptical rotor 5, thereby preventing the elliptical rotor 5 from being subjected to a large force and falling off the arch plate 3. The overall structure prolongs the service life of the guardrail.

[0034] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
