[0017] The present invention will be further described below by way of examples, but the scope of the present invention is not limited thereto.

[0018] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0019] like Figure 1-9 As shown, a road collision avoidance vehicle is composed of four main parts: a working vehicle 10, a hydraulic flipping mechanism 20, a buffer device 30 and an anti-collision pad 40.

[0020] The anti-collision buffer structure is connected to the rear of the working vehicle 10 through a hydraulic flip mechanism 20. The anti-collision buffer structure consists of a buffer device 30 and an anti-collision pad 40. The anti-collision pad 40 consists of a cover plate 401, a rubber pad 402, a fixing seat 403, a fixing cylinder 404, a support cylinder 405, an arched support plate 406, a hinge A407 and a hinge B408. Two fixing rods are welded on the fixing seat 403 and threaded holes are drilled on the upper end surface of the fixing rod. The two fixing rods are fixed with a fixing cylinder 404 and the annular rubber pad 402 is fixed by the fixing cylinder 404. The rubber pad 402 is supported by a support cylinder 405 and an arched support plate 406. The two ends of the arched support plate 406 are inserted into the gap between the rubber pad and the fixing cylinder. The support cylinder 405 and the fixing cylinder 404 are both composite materials of EVA and polyurethane. This material is elastic and anti-collision. Wear-resistant, the material of the arched support plate 406 is elastic steel and the overall curvature of the front end is 320° and the rear end is a triangular structure. The two support rollers 405 are connected to the front and rear ends of the arched support plate 406 respectively through hinges A407 and hinges B408 to ensure the stability of the internal support structure as a whole, thereby improving the buffering performance of the anti-collision pad, thereby protecting the front of the impact vehicle from excessive deformation. Specifically, a pivot is fixed in the middle of the front and rear ends of the arched support plate, and the two ends of the connecting rod are rotatably connected to the pivot to form corresponding hinges A and hinges B; at the same time, there are triangular protrusions on both sides of the fixed seat 403, and the triangular protrusions use the side faces of the fixed seat as right angles, which are used to cooperate and fix with the inverted triangular notches on the front fixed plate 304 of the buffer device 30. In order to facilitate installation, the matching relationship between the two is a transition match.

[0021] During installation, first assemble the anti-collision pad into a whole except the cover plate, then insert the triangular protrusion of the whole into the inverted triangular notch on the front fixing plate 304, cover the cover plate, and fix it with bolts. This can realize pre-assembly of scattered parts and components, and improve the assembly efficiency of the whole machine.

[0022] The buffer device 30 is composed of a rear fixing plate 301, an energy absorption box 302, a support rod 303, a front fixing plate 304 and a buffer block 305. The front fixing plate 304 has inverted triangular notches on both sides for installing the crash pad 40; two pairs of inwardly curved hollow support rods 303 and two energy absorption boxes 302 with arc-shaped sides are installed between the front fixing plate 406 and the rear fixing plate 301, and the rear fixing plate 301, the energy absorption box 302, the support rod 303 and the front fixing plate 304 are fixed by welding; the energy absorption box 302 is filled with a buffer block 305, which is a buffer shock-absorbing structure composed of multiple elliptical tubes 305a and support tubes 305b arranged in an interlaced and closely spaced manner. The material is a high-performance composite plastic, and the elliptical tube 305a is provided with support ribs inside, and the support ribs intersect at the focus of the ellipse ( Figure 8The supporting ribs between the elliptical tubes 305a are parallel to each other, which can ensure that the force is evenly transmitted in the buffer block 305 when impacted. Due to the special structural characteristics of the ellipse (the external force will be concentrated on two focal points), the buffer block 305 is not only more impact-resistant than the traditional hexagonal hollow aluminum buffer block, but also lighter and less expensive; four Φ8 threaded holes are opened on the surface of the rear fixing plate 301, which are used to be fixedly connected to the transmission connecting plate 201 of the hydraulic flipping mechanism 20.

[0023] The hydraulic flipping mechanism 20 consists of a transmission connecting plate 201, a hydraulic device 202 and a fixed plate 203. A 6mm groove is opened on one side of the transmission connecting plate 201 for cooperating with the rear fixed plate 301 for installation, and is fixed to the rear fixed plate 301 by bolts through four Φ8 circular holes on the surface; two groups of triangular steel plates are welded on the other side, and two reinforcing plates are added on both sides. The triangular steel plates are opened with Φ8 and Φ10 circular holes for cooperating with the hydraulic rod and the rotating shaft respectively, thereby realizing the linkage with the hydraulic device 202, and the hydraulic device 202 is connected and fixed to the working vehicle through the fixed plate 203.

[0024] During operation, the road operator drives the anti-collision vehicle to the front of the working section, starts the hydraulic device 202 and places the buffer device 30 equipped with the anti-collision pad 40 parallel to the ground through the transmission connecting plate 201. When a vehicle collides with the working vehicle due to failure to avoid, the anti-collision pad 40 first deforms to absorb part of the collision energy and protects the front of the collision vehicle from excessive deformation. Then, during the force transmission process, the support rod 303 of the buffer device 30 and the buffer block 305 in the energy absorption box 302 deform to further absorb the collision energy, thereby protecting the operator and the collision vehicle.

[0025] The road operation anti-collision vehicle of the present invention has a compact structure, small size, light weight, and simple operation. It can be applied to scenes such as urban block roads and urban express lanes, and can reduce or mitigate the occurrence of secondary traffic accidents and reduce the damage caused to the impacting vehicles to a certain extent.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
