As shown in fig. 1, the embodiment of the utility model provides an energy dissipation end for road guard rail (the viewing direction of fig. 1 is downwards from the top of road guard rail), this energy dissipation end includes interconnect's end grafting 22 and end casing 2, end grafting 22 is used for pegging graft with road guard rail 1, end casing 2 includes arc 21 and fixed plate 23, the one end bending extension that end grafting 22 was kept away from to arc 21 (that is to say, arc 21 is extended to the direction of fixed plate 23 by end grafting 22), arc 21 is connected in the top of fixed plate 23 in order to enclose jointly with fixed plate 23 and establish formation cushion chamber 20, fixed plate 23 passes through backup pad 3 and connects road guard rail 1.
In this embodiment, the arc plate 21 is provided, so that when the vehicle impacts the energy dissipation end laterally or obliquely, the energy dissipation end tends to deflect towards the outside of the road, and the support plate 3 is connected with the road protection fence 1, so that the road protection fence 1 can be inclined, direct impact on the vehicle is avoided, and the risk that all parts of the road protection fence 1 are inserted into the vehicle body is reduced. Compared with the surface with edges, the arc-shaped plate 21 enhances the surface area contacted with the vehicle body when collision occurs, has small pressure on the vehicle body, and is not easy to be inserted into the vehicle body to damage the vehicle body; and the arc plate 21 is more easily inwards sunken when being impacted, thereby playing a role in buffering.
As shown in fig. 2, in one embodiment, an impact-resistant plate-like structure is provided in the cushion chamber 20, and both ends of the impact-resistant plate-like structure are connected to the head housing 2, the impact-resistant plate-like structure being used to absorb kinetic energy of a vehicle impact. When a vehicle impacts the energy dissipation end head, the impact resistant plate-shaped structure can deform, so that part of impact force on the vehicle can be offset.
In one embodiment, as shown in fig. 2, the transverse cross-sectional shape of the impact resistant plate-like structure is an arc, and the arc-shaped impact resistant plate-like structure 24 extends from the terminal insertion part 22 toward the fixing plate 23. The curved impact-resistant plate-like structure 24, which is similar to the curved plate 21 in shape, can resist the impact energy of a vehicle and at the same time, can cause the road guard rail to tend to topple towards the outside of the road.
As shown in fig. 2, in one embodiment, the number of the impact-resistant plate-shaped structures is multiple, and the multiple impact-resistant plate-shaped structures are sequentially arranged at intervals from the arc-shaped plate 21 to the fixing plate 23.
As shown in fig. 3, in one embodiment, the transverse cross-sectional shape of the impact resistant plate structure is a wave shape, one end of the wave-shaped impact resistant plate structure 25 is located at the terminal insertion part 22, and the other end of the wave-shaped impact resistant plate structure 25 is connected to the fixing plate 23. Compared with the arc-shaped impact-resistant plate-shaped structure 24, the wavy impact-resistant plate-shaped structure 25 has a larger expansion area, so that a larger deformation amount can be generated when the shock-resistant plate-shaped structure is impacted, and the buffering effect is enhanced.
In one embodiment, the corrugated impact resistant plate-like structure 25 is made of carbon spring steel or alloy spring steel. Due to the elasticity of the material itself, the wavy impact-resistant plate-shaped structure 25 made of carbon spring steel or alloy spring steel can exert a better cushioning effect.
As shown in fig. 4, in one embodiment, the buffer chamber 20 is provided with a partition 26, the partition 26 longitudinally divides the buffer chamber 20 into two chambers, and one of the chambers 20 is filled with an elastic buffer 27.
In one embodiment, the resilient cushion 27 comprises rubber or coconut palm.
In one embodiment, restraining ropes 4 are provided between posts (not shown) of the road guard rail 1. When the vehicle side hits the energy dissipation end, due to the existence of the restraining ropes 4, a plurality of continuous upright posts are easy to topple towards the outer side of the road, and the damage to the vehicle is reduced.
In one embodiment, the support plate 3 is located between the arc plate 21 and the fixing plate 23, the support plate 3 is provided with support plate tips 31; the thickness of the support plate tip 31 is greater than the thickness of the support plate 3. The cross-section of the support plate ends 31 may be arcuate, circular or rectangular. When tip shell 2 is completely collapsed, support plate 3 provided with rectangular support plate tip 31 reduces the risk of insertion into the vehicle body as compared to support plate 3 without support plate tip 31.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
