Abstract
The invention discloses a multi-stage buffer bumper. The multi-stage buffer bumper comprises a front crossbeam and a back crossbeam. The back crossbeam is arranged on the front crossbeam. A buffer support frame is arranged between the front crossbeam and the back crossbeam. Left and right sides of the buffer support frame are provided with buffer support plates. Multiple air bags are arranged among the buffer support plates and the front crossbeam. Shock absorbers are arranged between the buffer support frame and the front crossbeam and between the buffer support frame and the back crossbeam. Multiple buffer springs are arranged inside of the buffer support frame.By adoption of the above mode, the multi-stage buffer bumper is capable of absorbing energy in a multi-stage mode in order to greatly reduce collision-induced impact and prevent a vehicle body against damage. The multi-stage buffer bumper has a simple structure and is safe and reliable.
Description
Technical field
The present invention relates to Federal bumper field, particularly relate to a kind of multi-buffer bumper/spoiler.
Background technology
Federal bumper absorbs to relax foreign impacts power, the safety device of protection vehicle body front and rear part.When colliding, bumper/spoiler can protect vehicle body, avoids vehicle body directly to collide.For low speed collision, it can be played a protective role by dispersing impact forces; For the collision of speed, it is energy limited efficiency, and protective effect also has limitation.Existing bumper/spoiler is mainly rigidly attached on chassis, when colliding, himself can absorb some energy, quite a few is then delivered on vehicle body, thus cause vehicle body breakage and personal casualty, although some bumper/spoiler also has energy-absorbing function, cause limited efficiency because energy-absorbing is unbalanced.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of multi-buffer bumper/spoiler, can multistage energy-absorbing, significantly reduces the impact of clashing into and bringing, and prevent vehicle body damaged, structure is simple, safe and reliable.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of multi-buffer bumper/spoiler, comprise: front cross rail and after cross member, described after cross member is installed on front cross rail, cushioning supportive frame is provided with between described front cross rail and after cross member, the described cushioning supportive frame left and right sides is provided with cushioning supportive plate, multiple air bag is provided with between described cushioning supportive plate and front cross rail, described cushioning supportive frame is provided with bumper respectively and between front cross rail and after cross member, is provided with multiple recoil spring inside described cushioning supportive frame.
In a preferred embodiment of the present invention, described cushioning supportive frame is rhombus, and four tops of described cushioning supportive frame are connected on front cross rail, after cross member and buffering stay bearing plate.
In a preferred embodiment of the present invention, the two ends of described cushioning supportive plate are connected on front cross rail and after cross member.
In a preferred embodiment of the present invention, the quantity of described air bag is 4, described front cross rail be each side provided with 2 air bags.
In a preferred embodiment of the present invention, the quantity of described recoil spring is 3, and it is inner that described recoil spring is disposed in an evenly spaced relation in cushioning supportive frame.
The invention has the beneficial effects as follows: level buffer bumper of the present invention, can multistage energy-absorbing, significantly reduce the impact of clashing into and bringing, prevent vehicle body damaged, structure is simple, safe and reliable.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of multi-buffer bumper/spoiler one of the present invention preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, front cross rail, and 2, after cross member, 3, cushioning supportive frame, 4, air bag, 5, bumper, 6, recoil spring, 7, cushioning supportive plate.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, a kind of multi-buffer bumper/spoiler, comprise: front cross rail 1 and after cross member 2, described after cross member 2 is installed on front cross rail 1, be provided with cushioning supportive frame 3 between described front cross rail 1 and after cross member 2, described cushioning supportive frame 3 left and right sides is provided with cushioning supportive plate 7, is provided with multiple air bag 4 between described cushioning supportive plate 7 and front cross rail 1, described cushioning supportive frame 3 is provided with bumper 5 respectively and between front cross rail 1 and after cross member 2, is provided with multiple recoil spring 6 inside described cushioning supportive frame 3.
In addition, state cushioning supportive frame 3 for rhombus, four tops of described cushioning supportive frame 3 are connected on front cross rail 1, after cross member 2 and buffering stay bearing plate 7.
In addition, the two ends of described cushioning supportive plate 7 are connected on front cross rail 1 and after cross member 2.
In addition, the quantity of described air bag 4 is 4, described front cross rail 1 be each side provided with 2 air bags 4.
In addition, the quantity of described recoil spring 6 is 3, and it is inner that described recoil spring 6 is disposed in an evenly spaced relation in cushioning supportive frame 3.
Be different from prior art, level buffer bumper of the present invention, can multistage energy-absorbing, significantly reduce the impact of clashing into and bringing, prevent vehicle body damaged, structure is simple, safe and reliable.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
