At present, existing back buffer beam is all the structure that anticollision back plate coordinates two energy-absorption boxes mostly, its minibus
Can be low, the tailstock and headstock of the fore-aft vehicle after shock all can gross distortions.
The content of the invention
To solve the above problems, the invention discloses a kind of new automobile back buffer beam assembly.
In order to reach object above, the present invention provides following technical scheme：
A kind of new automobile back buffer beam assembly, it is characterised in that：Including back buffer beam body, the back buffer beam body includes
Back buffer beam outside plate, back buffer beam inner panel and the support block set gradually from outside to inside, the back buffer beam outside plate in middle part to
The arc tabular of outer lug, the inner side both ends of back buffer beam outside plate are respectively equipped with energy-absorption box, the back buffer beam inner panel and support
Block is arranged between two energy-absorption boxes, and the back buffer beam inner panel is in the hollow arc tabular being adapted with back buffer beam outside plate,
Its outside is arranged in sequence with the arc that middle part caves inward from left to right with being close on the inside of back buffer beam outside plate in hollow structure inside
Shape elastic plate, and space in addition to arc elastic plate be filled with buffer liner in back buffer beam inner panel, the support block outside
Side is the arcwall face being adapted with back buffer beam inner panel medial surface, and cushion is provided between support block and back buffer beam inner panel.
Further, in addition to buffer plate, the support block and energy-absorption box are arranged on buffer plate.
Further, the left and right ends of the buffer plate are additionally provided with symmetrical limited post.
Further, one end of the limited post is fixedly connected with buffer plate, and the other end is nested in back buffer beam outside plate
It is internal.
Compared with prior art, the beneficial effects of the present invention are：Using back buffer beam inner panel, by past from a left side inside it
Right evenly distributed arc elastic plate can preferably bear the impulsive force for coming from back buffer beam outside plate, and combine buffer liner,
Effectively improve the impact resistance and shock-absorbing capacity of back buffer beam inner panel；, can by the arcwall face and cushion on the outside of support block
Effectively support back buffer beam inner panel, and shock-absorbing capacity is further improved with reference to cushion；Using buffer plate, after improving entirety
The resiliency of collision prevention girders；By limited post, when being hit in the middle part of back buffer beam outside plate, collision prevention girders outside plate is due to middle part stress
Indent, both ends can produce the thrust to both sides, and both ends limited post can provide support force, slow down the deformation of collision prevention girders outside plate, carry
The impact resistance of high back buffer beam outside plate.

Embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following embodiments are only
For illustrating the present invention rather than limitation the scope of the present invention.
As illustrated, a kind of new automobile back buffer beam assembly, including back buffer beam body, back buffer beam body include by
It is outer outside in middle part to interior back buffer beam outside plate 1, back buffer beam inner panel 2 and the support block 3 set gradually, back buffer beam outside plate 1
Raised arc tabular, the inner side both ends of back buffer beam outside plate 1 are respectively equipped with energy-absorption box 4, back buffer beam inner panel 2 and support block 3
It is arranged between two energy-absorption boxes 4, back buffer beam inner panel 2 is in the hollow arc tabular that is adapted with back buffer beam outside plate 1, outside it
Side is close to the inner side of back buffer beam outside plate 1, is arranged in sequence with the arc that middle part caves inward in hollow structure inside from left to right
Elastic plate 5, and the space in back buffer beam inner panel 2 in addition to arc elastic plate 5 is filled with buffer liner 6, the outside of support block 3
For the arcwall face being adapted with the medial surface of back buffer beam inner panel 2, and cushion 7 is provided between support block 3 and back buffer beam inner panel 2.
When receiving shock, external impacts back buffer beam outside plate 1, collision prevention girders outside plate 1 deform upon first, now rear anti-crash
Arc elastic plate 5 evenly distributed from left to right can preferably bear to come from the deformation power of back buffer beam outside plate 1 in beam inner panel 2,
Arc elastic plate 5 can play the speed for slowing down the deformation of back buffer beam inner panel 2, and then slow down the rate of deformation of back buffer beam outside plate 1,
And buffer liner 6 is combined, impact resistance and shock-absorbing capacity are effectively improved, and after the arcwall face in the outside of support block 3 can play support
The middle part of collision prevention girders outside plate 1 and back buffer beam inner panel 2, and effectively scattered middle part stress, further improve impact resistance and buffering
Performance.
In the present embodiment, in addition to buffer plate 8, support block 3 and energy-absorption box 4 are arranged on buffer plate 8.When after
Collision prevention girders are impacted formula, and buffer plate 8 can improve the resiliency of overall back buffer beam.
In the present embodiment, the left and right ends of buffer plate 8 are additionally provided with symmetrical limited post 9, and one end of limited post 9 is with delaying
Rush backing plate 8 to be fixedly connected, the other end is nested in inside back buffer beam outside plate 1.When the middle part of back buffer beam outside plate 1 is hit,
In the presence of external force, the middle part meeting stress indent of collision prevention girders outside plate 1 so that the both ends of collision prevention girders outside plate 1 can be produced to both sides
Thrust carries out deformation, and can provide support force by both ends limited post 9, effectively slows down the deformation of collision prevention girders outside plate 1, extends deformation
Time, and then the impact resistance of back buffer beam outside plate 1 is improved, play cushioning effect.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, in addition to
Formed technical scheme is combined by above technical characteristic.It should be pointed out that for those skilled in the art
