Technical Field

[0001] The invention relates to the field of safety protection, and in particular to an assembled anti-collision guardrail with a built-in origami-shaped energy-absorbing and buffering device. Background Art

[0002] Anti-collision guardrails, also known as traffic safety guardrails or collision buffer facilities, are a type of traffic infrastructure designed to reduce the risk of vehicle damage and occupant injury when a vehicle deviates from its normal driving path. They are usually installed on the edge of the road, on both sides of bridges, in the central median, and in dangerous sections such as sharp turns and intersections.

[0003] Most of the current anti-collision guardrails are made of cables or corrugated metal plates with a relatively simple structure. They can stop vehicles when a traffic accident occurs, but it is difficult to absorb and buffer the impact force generated by the vehicle, which can easily cause injuries to people in the vehicle and has a poor protective effect.

[0006] Furthermore, the energy absorption component includes an anti-collision column, and the anti-collision column is fixedly connected to the top of the two embedded bases, the anti-collision column is made of highly elastic rubber, the fixed pile is located in the anti-collision column, and four arc-shaped elastic washers are fixedly connected to the two anti-collision columns, the four arc-shaped elastic washers located in the same anti-collision column form a group, the fixed pile is in contact with the side of the four arc-shaped elastic washers in the same group that are close to each other, the top of the two anti-collision columns are fixedly connected to debris filters, and three anti-collision beams are fixedly connected between the two anti-collision columns.

[0007] Furthermore, the shock absorbing assembly includes a mounting bolt, three of the mounting bolts are fixedly connected to the two anti-collision columns, two of the mounting bolts are fixedly connected to the three anti-collision beams, four of the mounting bolts located at the same level form a group, a connecting plate is fixedly connected between the four mounting bolts in the same group, three corrugated plates are fixedly connected to the three connecting plates, the three corrugated plates located on the same connecting plate form a group, a buffer plate is fixedly connected between the three corrugated plates in the same group, a dustproof shell is fixedly connected to the buffer plate, the dustproof shell is slidably connected to the connecting plate, a number of unloading wheels are rotatably connected to the buffer plate, a number of the unloading wheels located on the same buffer plate form a group, and four reflective warning strips are fixedly connected to the number of unloading wheels.

[0008] Furthermore, it also includes a buffer assembly, which is arranged between the connecting plate and the buffer plate, and the buffer assembly includes a sliding base, four sliding bases are fixedly connected to the three connecting plates, two bottom bolts are slidably connected to the sliding base, and the two bottom bolts of the same sliding base form a group, four top bolts are fixedly connected to the three buffer plates, and a connecting swing frame is rotatably connected between the top bolts and the two bottom bolts of the same group, each mounting bolt is fixedly connected to a sleeve, the sleeve passes through the connecting plate, and four sleeves located in the same plane form a group, four sliding shafts are fixedly connected to the three buffer plates, the sliding shafts are slidably connected to the sleeves, a buffer spring is connected between the buffer plate and the four sleeves of the same group, and the buffer spring is sleeved on the sliding shaft.

[0009] The present invention has the following advantages: when a vehicle collides with the guardrail, the three sets of unloading wheels will unload the impact force generated by the vehicle, slow down the vehicle and change the collision direction of the vehicle to a certain extent, thereby preventing the vehicle from running off the road and falling; at the same time, the corrugated plate will be deformed by the impact, thereby being able to buffer and absorb the impact force; then the swing of the anti-collision column will squeeze the arc-shaped elastic tile, and the fixed column will resist the anti-collision column; when the guardrail is hit by the vehicle, it will swing back to a certain extent to unload the force; at the same time, it will rebound and swing back to reset under the elastic action of the arc-shaped elastic tile, thereby further buffering and unloading the impact force of the vehicle, thereby better protecting the safety of the people on the vehicle; and the reflective warning strip on the unloading wheel will guide and warn the driver when illuminated by the headlights.

[0010] When the three groups of unloading wheels drive the three buffer plates to move horizontally respectively, the buffer spring will be compressed, and the horizontal movement of the top bolt will also drive the two connecting swing frames of the same group to swing. The swinging of the two connecting swing frames of the same group will respectively drive the two bottom bolts of the same group to move away from each other, and then the buffer spring will reset. The reset of the two connecting swing frames of the same group will respectively drive the two bottom bolts of the same group to move towards each other and reset. In this way, the impact force of the vehicle can be further absorbed and buffered, so that the injuries to people in a traffic accident are less. BRIEF DESCRIPTION OF THE DRAWINGS

A shock absorbing component is arranged on the energy absorbing component, and the shock absorbing component is used to reduce the shock of the vehicle.

[0022] The energy absorption component includes an anti-collision column 31. The tops of the two embedded bases 1 are connected to the anti-collision columns 31 by bolts.
