Description
Technical field
The utility model relates to bumper/spoiler technical field, particularly a kind of automotive rear anti-collision bumper/spoiler.
Background technology
At present, in automobile body accessories anticollision device field, Federal bumper, as the requisite important safety parts of vehicle, plays an important role.Federal bumper is the safety device absorbing the foreign impacts power that relaxes, protection vehicle body front and rear part.
Federal bumper is arranged on the front and rear of automobile usually, and when being collided for preventing automobile, automobile is impaired, the safety of protection automobile and occupant, and the structure of front/rear collision bumper is all not identical; The crashproof buffering effect of existing automobile rear bumper is not very desirable, more weak for the protection of knocking into the back.Therefore be necessary to carry out technical innovation further to the structure of existing automobile rear bumper.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, provides a kind of structure simple, automotive rear anti-collision bumper/spoiler reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of automotive rear anti-collision bumper/spoiler described in the utility model, comprise collision prevention girders and two foams, described collision prevention girders is provided with front end face and bottom face, the two side ends of described front end face is symmetrically arranged with two grooves matched mutually with foam along its length, and described foam one end is all fixedly embedded in a groove; The middle end face of described front end face is provided with several Buffer Units along its length, arranges between every two Buffer Units in gap; Described bottom face is provided with several joint pins along its length.
Further, described Buffer Unit is made up of two springs and dash plate, and two spring one end and dash plate surface are fixedly connected, and the middle end face of two spring other ends and front end face is fixedly connected.
Further, the quantity of described Buffer Unit is four.
Further, the length of described foam is identical with the length of collision prevention girders.
Further, the height after described spring-compressed deformation is less than the height of foam.
After adopting said structure, the utility model beneficial effect is: a kind of automotive rear anti-collision bumper/spoiler described in the utility model, comprise collision prevention girders and two foams, described collision prevention girders is provided with front end face and bottom face, the two side ends of described front end face is symmetrically arranged with two grooves matched mutually with foam along its length, and described foam one end is all fixedly embedded in a groove; The middle end face of described front end face is provided with several Buffer Units along its length, arranges between every two Buffer Units in gap; Described bottom face is provided with several joint pins along its length.When using the utility model; by the Buffer Unit in collision prevention girders, energy-absorbing and buffering are carried out to external force; by the foam of two in collision prevention girders, energy-absorbing and buffering are carried out to external force; drastically increase the crashproof buffering effect of automobile rear bumper; effectively prevent rear-end collision and the personnel casualty accidents that causes, the safety of protection automobile and occupant.It is simple that the utility model has structure, arranges rationally, the advantages such as cost of manufacture is low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As Figure 1-3, a kind of automotive rear anti-collision bumper/spoiler described in the utility model, comprise collision prevention girders 1 and two foams 3, described collision prevention girders 1 is provided with front end face 1-1 and bottom face 1-2, the two side ends of described front end face 1-1 is symmetrically arranged with two groove 1-1a matched mutually with foam 3 along its length, and described foam 3 one end is all fixedly embedded in groove 1-1a; The middle end face of described front end face 1-1 is provided with several Buffer Units along its length, arranges between every two Buffer Units in gap; Described bottom face 1-2 is provided with several joint pins 2 along its length.
Further, described Buffer Unit is made up of two springs 4 and dash plate 5, two spring 4 one end and dash plate 5 surface are fixedly connected, and the middle end face of two spring 4 other ends and front end face 1-1 is fixedly connected, and two connection modes all can adopt and be welded and fixed.Dash plate 5 can adopt iron plate or iron sheet to be made, and when dash plate 5 damages, comparatively easily changes, and can be car owner's maintenance cost saving like this.
Further, the quantity of described Buffer Unit is four.
Further, the length of described foam 3 is identical with the length of collision prevention girders 1, improves buffering energy-absorbing function.In addition, fixing between foam 3 and groove 1-1a is mainly close to leakproof fit and glue is pasted, and when foam 3 damages, comparatively easily changing, can be car owner's maintenance cost saving like this.
Further, height after described spring 4 compression set is less than the height of foam 3, when there is compression set by External Force Acting in spring 4, when the height after spring 4 compression set is identical with the height of foam 3, spring 4 and foam 3 can together with do buffering energy-absorbing, greatly improve the safety performance of bumper/spoiler.
When using the utility model, carry out energy-absorbing and buffering by the Buffer Unit in collision prevention girders to external force, this is as first time buffering; By the foam of two in collision prevention girders, energy-absorbing and buffering are carried out to external force, the conduct second time buffering; By twice buffering, drastically increase the crashproof buffering effect of automobile rear bumper, effectively prevent rear-end collision and the personnel casualty accidents that causes, the safety of protection automobile and occupant.In addition, this structure is simple, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
