The utility model discloses a rear crash barrier of a lorry. The rear crash barrier comprises a crash bar and a support provided with a mounting hole, wherein the shape of the cross section of the crash bar is as follows: the middle part is of the shape of U and the two side edges of the U shape respectively outwards extend and are bent to form arc-shaped curved hooks; and the support is fixedly connected with the flat bottom part of the U-shaped middle part of the crash bar. The rear crash barrier disclosed by the utility model has the advantages of simple structure and capabilities of increasing the area for buffering stress and improving the buffering effect, and can be widely applied to lorries.
Description
Technical field
The utility model relates to the parts on the automobile, refers more particularly to lorry rear anti-crash guardrail.
Background technology
For the dolly that prevents to knock into the back creeps in the truck chassis, cause casualties,, lorry all requires the rear anti-crash guardrail to be installed when dispatching from the factory at the lorry afterbody; But present stage, mostly the crash bar of the rear anti-crash guardrail of most of lorry is the hollow cylinder structure; Not only the cost cost is high, waste material; And owing to be the narrow and small tube sheet of mono-, area of thrust surface are little, can not play crashproof buffer action well; Such rear anti-crash guardrail not only can not alleviate the vehicle collision degree sometimes, the extent of injury that has even also can add serious accident.
The utility model content
The utility model has overcome deficiency of the prior art, and a kind of simple in structure, lorry rear anti-crash guardrail with big area of thrust surface, high buffering effect is provided.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: described lorry rear anti-crash guardrail; Comprise crash bar and the support that is provided with mounting hole; Wherein: the shape of cross section of said crash bar is: the intermediate portion is " U " shape shape, and the dual-side of " U " shape shape stretches out respectively and bends to the arc hook solid; Said support is captiveed joint with the flat of bottom of " U " shape shape of crash bar centre portion.
Further, aforesaid lorry rear anti-crash guardrail, wherein: described support two ends are provided with flange.
Through adopting technique scheme, the utility model compared with prior art has the following advantages: simple in structure, increased the buffering area of thrust surface, improved buffering effect.
Description of drawings
Fig. 1 is the structural representation of the described lorry rear anti-crash of the utility model guardrail.
Fig. 2 is the structural representation of the left apparent direction of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Like Fig. 1, shown in Figure 2, described lorry rear anti-crash guardrail comprises: crash bar 1, support 2, mounting hole 3, flange 21; Wherein: the shape of cross section of crash bar 1 is: centre portion is " U " shape shape; And the dual-side of " U " shape shape stretches out respectively and bends to the arc hook solid, and this structure has not only increased crash-proof area of thrust surface, and because the object of circular shape has the excellent in cushioning properties ability; So the crash bar 1 of this structure has also had excellent in cushioning properties can; When automobile is accidentally impacted, can reduce the impact that passengers inside the car and vehicle body receive, improved the safety of automobile; Support 2 fixes with welding manner with the flat of bottom of " U " shape shape of crash bar 1 centre portion; In addition, the two ends that the support 2 of mounting hole 3 is housed are provided with flange 21, have increased the welding fixed-area of support 2 with crash bar 1, the safety that has improved automobile; That the lorry rear anti-crash guardrail of said structure has is simple in structure, increased the buffering area of thrust surface, improved the advantage of buffering effect.
