Description
Technical field
The present invention relates to automobile technical field, more particularly to a kind of combined type automobile back buffer beam.
Background technology
Anticollision girder steel is the U-lag formed with cold-rolling steel-plate punch, is connected with longitudinal beam, as vehicle passive safety
First of barrier, anticollision girder steel are absorption and relax foreign impacts power, the important safety of protection vehicle body front and rear part.
At present, the back buffer beam body of existing back buffer beam is the molding platy structure of integrated punching mostly, it is in quilt
Hit deformation after will integral replacing, considerably increase maintenance and repair cost.
The content of the invention
To solve the above problems, the invention discloses a kind of combined type automobile back buffer beam.
In order to reach object above, the present invention provides following technical solution：
A kind of combined type automobile back buffer beam, it is characterised in that：Including back buffer beam body, energy-absorption box and fixed plate, institute
Stating back buffer beam body includes base and anticollison block, and the base includes bottom plate and is symmetricly set on the side at plate outer side both ends
Plate, the anticollison block are sequentially arranged between biside plate from left to right, and the anticollison block includes grafting block, the grafting block outside
Equipped with fixed block, and grafting block is respectively arranged on the left side and the right side strip groove and strip bulge, is provided inwardly with the outside of the fixed block
Groove, is equipped with buffer stopper and spring in the groove, and the buffer stopper outside is in cambered surface, the both ends of the spring respectively with buffer stopper
Inner side is connected with bottom portion of groove, and the strip groove and strip bulge are adapted, and it is fixed to be respectively equipped with the inside of the left and right sides plate
Position is raised and positioning groove, the positioning protrusion and positioning groove are adapted with strip groove and strip bulge respectively, the suction
Energy box is distributed between base and fixed plate.
Further, the buffer stopper is damping rubber block.
Further, the fixed block is rubber fixed block.
Compared with prior art, the beneficial effects of the present invention are：It is whole anti-to form to employ knockdown anticollison block
Hit beam body, on the one hand, anticollison block can effectively slow down impact force, raising cushion performance is another self by buffer stopper and spring
Aspect, anticollison block are independent individual, and collision prevention girders body is formed by being mutually inserted, can be according to actual feelings after being hit
Condition, removable parts anticollison block, and since by the way of being mutually inserted, not only disassembling, assembling and replacing is convenient, also a saving dimension
Protect maintenance cost；By using evenly distributed energy-absorption box, the cushion performance of overall collision prevention girders body is can further improve, is improved
Safety coefficient.

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 limiting the scope of the invention.
A kind of as shown in the figure, combined type automobile back buffer beam, it is characterised in that：Including back buffer beam body 1, energy-absorption box 2
With fixed plate 3, back buffer beam body 1 includes base 4 and anticollison block 5, and base 4 includes bottom plate 41 and is symmetricly set on outside bottom plate 41
The side plate 42 at side both ends, anticollison block 5 are sequentially arranged between biside plate 42 from left to right, and anticollison block 5 includes grafting block 51, grafting
The outside of block 51 is equipped with fixed block 52, and grafting block 51 is respectively arranged on the left side and the right side strip groove 53 and strip bulge 54, fixed block
52 outsides are provided inwardly with groove 55, and buffer stopper 56 and spring 57 are equipped with groove 55, are in cambered surface on the outside of buffer stopper 56,57 liang of spring
End is connected with the inner side of buffer stopper 56 and 55 bottom of groove respectively, and strip groove 53 and strip bulge 54 are adapted, left and right sides plate
42 inner sides are respectively equipped with positioning protrusion 6 and positioning groove 7, positioning protrusion 6 and positioning groove 7 respectively with strip groove 53 and bar shaped
Protrusion 54 is adapted, and energy-absorption box 2 is distributed between base 4 and fixed plate 3.
Present invention employs knockdown anticollison block 5 to form whole collision prevention girders body 1, on the one hand, when being hit,
Since the outside of buffer stopper 56 of anticollison block 5 is in cambered surface so that buffer stopper 56 can preferential contact be impacted a little, then pass through spring 57
Deformation come effectively slow down shock kind excitation, improve cushion performance, on the other hand, anticollison block 5 is independent individual, adjacent two
Collision prevention girders body 1 is formed by being mutually inserted between anticollison block 5, can be according to actual conditions, removable parts quilt after being hit
The anticollison block 5 damaged after shock, and since by the way of being mutually inserted, not only disassembling, assembling and replacing is convenient, also a saving
Maintenance and repair cost.
In the present embodiment, buffer stopper 56 is damping rubber block, and fixed block 52 is rubber fixed block, when impact is spent greatly
When, in addition to by the cushioning effect of spring 57, damping rubber block and rubber fixed block can also play cushioning effect at the same time.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in the above embodiment, further includes
Formed technical solution is combined by above technical characteristic.It should be pointed out that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
