Preferably, the anticollision beam body has the two sides being oppositely arranged along its width direction, wherein on the end face of side
It is provided with the groove being recessed to the collision prevention girders body interior, is the open sky in end face with the other side that the side is oppositely arranged
Cavity configuration, the groove are formed in the cavity structure from the bottom of the cavity structure to the open end of the cavity structure
The protrusion of protrusion.
Preferably, the tail collision prevention girders further include the connecting column for being separately positioned on the both ends of the anticollision beam body, institute
Connecting column is stated to connect with vehicle energy absorption box.
Further, the both ends of the anticollision beam body are respectively arranged with mounting hole, and the connecting column is arranged described
In mounting hole.
Further, every end of the anticollision beam body is respectively provided with there are two the connecting column.
Preferably, the tail collision prevention girders further include the reinforcing rib being arranged in the anticollision beam body.
Further, the material of the reinforcing rib is plastics, with the anticollision beam body integrated injection molding.
Further, the reinforcing rib is provided with multiple groups, is arranged along the length extending direction interval of the anticollision beam body.
Preferably, the anticollision beam body extends along a length thereof the domed structure in direction.
The present invention also provides a kind of automobiles, have tail collision prevention girders as described in any one of the above embodiments.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：Automobile of the invention
Tail anticollision girder construction is simple, and light weight and cost is low, shock resistance and cushion energy absorbing property are good, and when car crass can reduce secondary wound
Harmful risk.
Detailed description of the invention
Attached drawing 1 is the perspective view of car tail collision prevention girders of the invention；
Attached drawing 2 is the front view of car tail collision prevention girders of the invention；
Attached drawing 3 is the right view of car tail collision prevention girders of the invention；
Attached drawing 4 is the left view of car tail collision prevention girders of the invention.
Specific embodiment
The technical solution of the present invention will be further described below with reference to the accompanying drawings.
As shown in Fig. 1 ~ Fig. 4, car tail collision prevention girders of the invention include anticollision beam body 1.
Anticollision beam body 1 extends along a length thereof the domed structure in direction, and anticollision beam body 1 has opposite along its width direction
The two sides of setting are wherein provided with the groove 11 to the inner recess of collision prevention girders main body 1 on the end face of side, opposite with side to set
The other side set be the open cavity structure 12 in end face, groove 11 formed in cavity structure 12 from the bottom of cavity structure 12 to
The protrusion 13 of the open end protrusion of cavity structure 12.The anticollision beam body 1 being arranged in this way, so that the materials of anticollision beam body 1 are few,
It is light-weight, oil consumption can be reduced, to reduce cost, but also there is preferable intensity, so that the shock resistance of tail collision prevention girders
Performance and cushion energy absorbing property are good, can reduce the risk of the secondary injury in automobile collision procedure.
In the present embodiment, along the length extending direction of anticollision beam body 1, anticollision beam body 1 includes being located in the middle first
The second segment 1b and third section 1c of section 1a and the both ends for being separately positioned on middle section 1a, in first segment 1a, second segment 1b and third
Two grooves 11 extended along its length are provided on section 1c, two grooves 11 are arranged side by side along the vertical direction, thus
Two protrusions 13 arranged side by side along the vertical direction are formed in cavity structure 12.It is preferred that groove 11 on first segment 1a,
Groove 11 on second segment 2a and the groove 11 on third section 3a are along identical with the arcuate profile of anticollision beam body 1
Same camber line extends.
Tail collision prevention girders further include the connecting column 2 for being separately positioned on the both ends of anticollision beam body 1, and connecting column 2 is used for and vapour
The connection of vehicle energy-absorption box.Specifically, the both ends of anticollision beam body 1 are respectively arranged with mounting hole, connecting column 2 is arranged in the mounting hole
In.
In the present embodiment, every end of anticollision beam body 1 is respectively provided with to be used to connect with vehicle energy absorption box there are two connecting column 2
It connects.
Tail collision prevention girders further include the reinforcing rib 3 being arranged in anticollision beam body 1, by the way that reinforcing rib 3 is arranged, can further be mentioned
The intensity of the high anticollision beam body 1, to improve the shock resistance of tail collision prevention girders.
In the present embodiment, reinforcing rib 3 is arranged on the first segment 1a of anticollision beam body 1, and is located in cavity structure 12, adds
Strengthening tendons 3 are provided with multiple groups, and each group reinforcing rib 3 is arranged along the length extending direction interval of anticollision beam body 1.
Anticollision beam body 1 uses plastic material, is formed by injection molding machine integral molded plastic, specific manufacturing process is：By plastics
Using injection molding machine by setting pressure injection mold, then pressure maintaining cools, demoulds later, so just completes anticollision material
The production of beam body 1, this makes the production process of the anticollision beam body 1 simple.Reinforcing rib 3 also uses plastic material, can
