Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As depicted in figs. 1 and 2, multistage protection bumper/spoiler of the present invention, comprise at least two anti-collision upright posts 3, some connecting cross beams 1 are set between anti-collision upright post 3, the anti-collision upright post arranged outside of both sides has flank 2, connecting cross beam 1, flank 2 and anti-collision upright post 3 form a U-shaped bumper, or yi word pattern bumper, this bumper/spoiler is fixedly connected with car chassis crossbeam by Buffer Unit, wherein: Buffer Unit is made up of the slide bar 16 of slide rail and the supporting setting of slide rail, the recoil spring 12 that some length do not wait is provided with in slide rail inside, deformation direction and the slide bar activity direction of recoil spring 12 are consistent, when collision happens accident, recoil spring 12 enters crashproof buffer status according to the ascending classification successively of the size of impact force, pushing tow slide bar 16, multistage protection protection is formed to the vehicle that crashes, the flexibility formed when vehicle generation head-on crash is protected step by step thus.
Wherein, slide rail one end is fixedly connected with car chassis crossbeam by permanent seat 11, and slide bar 16 one end is fixedly connected with anti-collision upright post 3; Preferably, slide rail and slide bar 16 all adopt square tube, the spring perch 13 supporting with recoil spring 12 is provided with in pairs in slide rail and slide bar 16, namely the logarithm of spring perch 13 and the number of recoil spring 12 are consistent, wherein, the spring perch 13 be arranged in slide bar 16 is fixed on by recoil spring seat board 18 on the sidewall of anti-collision upright post 3, and recoil spring 12 is placed on spring perch 13; In addition, anti-collision upright post 3 is provided with anti-collision rubber, anti-collision rubber adopts foamed rubber; it is inner in cellular structure, and preferably, the height of anti-collision rubber matches with the knee height being knocked human body; formed by the buffer protection of thrusting into this, reduce by the injured degree of thrusting into.
The sidewall of anti-collision upright post 3 is provided with several trough type mounting holes 20, mounting hole 20 is coordinated to be provided with several circular holes on slide bar 16, slide bar 16 one end is fixed on mounting hole 20 by bolt of rear end plate 19, slide rail is set on slide bar 16, the position that wears of slide rail and slide bar 16 arranges several bolts 15 and is connected and fixed, when being subject to clashing into, bolt 15 ruptures, and slide bar 16 can start to slide in slide rail; Preferably, the contact surface of slide rail and slide bar 16 is provided with detent projection, falls back when this projection can stop slide bar to slide in slide rail, and at the end of preventing collision, automobile rebounds by recoil spring 12, causes man-made further destroy.In addition, because mounting hole 20 is trough type, therefore, the distance between anti-collision upright post 3 and car chassis crossbeam and the slippage between slide bar and slide rail can be regulated by regulating the installation site of slide bar 16 one end on mounting hole 20; With the protection requirements of satisfied different anti-collision level vehicle.
The arranged outside of guide rail has one section of rigidity energy-absorbing crumple pipe 14, this rigidity energy-absorbing crumple pipe is bellows form, this rigidity energy-absorbing crumple pipe is coordinated to have wedge 17 in the arranged outside of guide rod, after recoil spring 12 in Buffer Unit is fully compressed, wedge 17 is oppressed rigidity energy-absorbing crumple pipe 14 and is out of shape energy-absorbing, carry out buffering energy-absorbing to the energy that collision produces further, maximized reduction automobile is because colliding the damage caused.
As shown in Figure 3, preferably, flank 2 and connecting cross beam 1 all adopt pipe and the two junction is arranged on the inside of anti-collision upright post 3, flank 2 was provided with orifice plate 7 with the coupling end of connecting cross beam 1, the internal engagement of connecting cross beam 1 is crossed orifice plate 7 and is provided with extension spring 4, two pieces of one end crossing orifice plate 7 are articulated and connected by adapter shaft 6, and the other end is strained by extension spring 4 and fit together; One end of extension spring 4 is fixed in connecting cross beam 1, and what the other end of extension spring 4 held flank 2 by flexible connecting member 8 through the through holes that two pieces are crossed on orifice plate 7 crosses orifice plate 7; In addition, cross orifice plate 7 through two pieces and be provided with some steel ropes 10, steel rope 10 distributes in the horizontal direction, and steel rope 10 two ends are provided with snap close, the diameter of snap close was greater than the diameter of through hole on orifice plate 7, flank 2 be impacted distortion be separated with connecting cross beam 1 time, steel rope 10 ruptures by root; Preferably, one end of steel rope 10 is fixed end, and the other end is free end; Or the two ends of steel rope 10 are free end; Preferably, one end of extension spring 4 is connected with connecting cross beam 1 is adjustable, by the pulling force size of the adjustable extension spring of setting nut 54 pairs of flanks 2 by setting nut 5; Two pieces are provided with reset guide device between orifice plate 7 excessively, and the through hole that this device crosses supporting setting on orifice plate by the taper pin 9 that a piece excessively orifice plate are arranged and another block is formed.
As shown in Figure 4 and Figure 5, before automobile generation side impact, the state of flank 2 and connecting cross beam 1 as shown in Figure 4, the orifice plate 7 of crossing that the contact surface place of the two is arranged fits together closely under the effect of extension spring 4, two when automobile generation side impact, the contact jaw that flank 2 and connecting cross beam 1 are strained by extension spring 4 around adapter shaft 6 opened with certain angle, when side impact force rate is comparatively descended, one end because of steel rope 10 is free end, and now steel rope 10 is inoperative; After collision terminates, flank 2, under the application force of extension spring 4 and the guiding of reset guide device, recovers the position before initial collision; When side impact power is larger, the angle that the contact jaw that flank 2 and connecting cross beam 1 are strained by extension spring 4 opens around adapter shaft 6 increases, and now steel rope 10 starts to rupture gradually, cushions the energy because collision produces thus; Because being provided with some steel ropes 10, so, the energy produced collision is formed flexible buffer step by step by root steel rope 10, by automobile because the damage rate that side impact causes drops to minimum, similarly, after collision terminates, flank 2, under the application force of extension spring 4 and the guiding of reset guide device, recovers the position before initial collision.
In sum, multistage protection bumper/spoiler of the present invention can not only form classification flexible buffer to the frontal impact of automobile, and, still the damage rate of automobile can be reduced when automobile generation side impact.
Described just in order to the present invention is described above, be construed as the present invention and be not limited to above embodiment, meet the various variants of inventive concept all within protection scope of the present invention.
