Abstract
The invention discloses a vehicular anti-collision energy absorption box comprising an energy absorption pipe fitting mounted between a bumper and a longitudinal beam of a vehicle body. The length direction of the energy absorption pipe fitting is equal to the body length direction of the vehicle body, the energy absorption pipe fitting collapses and absorbs energy when being collided in the vehicle body direction, and the radial section of the energy absorption pipe fitting is octagonal. The energy absorption pipe fitting forming the energy absorption box is arranged to be octagonal, so that compared with a conventional quadrangular energy absorption box, the vehicular anti-collision energy absorption box has four more corners and is higher in strength and capable of absorbing energy better when being collided.
Description
Technical field
The present invention relates to vehicle safety field, be specifically related to a kind of collision prevention of vehicle energy-absorption box.
Background technology
Vehicle is in the time running impact front obstacle with higher speed, vehicle can be subject to very large momentum, producing larger obstruction acceleration/accel makes vehicle be down to static by high speed moment, originally larger kinetic energy almost all changes into the interior energy of vehicle, make vehicle be subject to serious destruction and distortion, cause the injures and deaths of personnel in driving compartment.Therefore in vehicle design, conventionally adopt the energy-absorption box that these energy of absorption are installed at front part of vehicle.At present, the energy-absorption box on market mostly is quadrangular section, and its structural strength is not high, does not reasonably arrange to add powerfully, and energy-absorbing effect is not good, in the time being subject to clashing into, can not absorb well energy.
Summary of the invention
The object of the present invention is to provide a kind of collision prevention of vehicle energy-absorption box, it can better absorb energy in the time being subject to clashing into.
The technical solution used in the present invention is: a kind of collision prevention of vehicle energy-absorption box, it is characterized in that: comprise the energy-absorbing pipe fitting being arranged between bumper/spoiler and chassis runner, the length direction of energy-absorbing pipe fitting is consistent with vehicle body height direction, crumple energy-absorbing when energy-absorbing pipe fitting is clashed into by vehicle body direction, the radial section of energy-absorbing pipe fitting is octagon.
Find by great many of experiments, be arranged to octagon by forming the energy-absorbing pipe fitting of energy-absorption box, with respect to traditional quadrangle energy-absorption box many four turnings, intensity is higher, in the time being subject to clashing into, can better absorb energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of grooved plate;
Fig. 3 is scheme of installation of the present invention;
Fig. 4 is the section drawing of Fig. 1.
The specific embodiment
The scheme that the present invention takes as shown in Figure 1,3, a kind of collision prevention of vehicle energy-absorption box, comprise the energy-absorbing pipe fitting 10 being arranged between bumper/spoiler and chassis runner, the length direction of energy-absorbing pipe fitting 10 is consistent with vehicle body height direction, crumple energy-absorbing when energy-absorbing pipe fitting 10 is clashed into by vehicle body direction, the radial section of energy-absorbing pipe fitting 10 is octagon.The radial section of energy-absorbing pipe fitting 10 is octagon, with respect to traditional quadrangle energy-absorption box many four turnings, intensity is higher, energy-absorbing effect is better.Certainly, the octagon here can be octagon or non-octagon, and eight limits do not comprise the little arc-shaped transition section forming between adjacent edge.
Further scheme is, energy-absorbing pipe fitting 10 is greater than other end caliber for Taper Pipe shape and one end caliber of being connected with chassis runner.Changing kind of a mode energy-absorbing pipe fitting 10 is Taper Pipe shapes, wherein large-diameter pipe section and chassis runner are affixed, this structure can guide the crumple direction of energy-absorbing pipe fitting 10, the pipe with small pipe diameter section of energy-absorbing pipe fitting 10 is shunk towards retraction Large Diameter Pipeline section one side gradually along pipe range direction, thereby it is bending to avoid energy-absorbing pipe fitting 10 to produce in endergonic process, guarantee actv. crumple distance, improve energy-absorbing effect.The tube wall upper punch of energy-absorbing pipe fitting 10 is pressed with the crumple reinforced rib 11 of strip, and the length direction of crumple reinforced rib 11 is vertical with the pipe range direction of energy-absorbing pipe fitting 10.Crumple reinforced rib 11 can play the effect of strengthening energy-absorbing pipe fitting 10 intensity, can play again the effect that guides energy-absorbing pipe fitting 10 crumple directions while being impacted.
More specifically scheme is, to be energy-absorbing pipe fitting 10 tube walls form to punching press inside body crumple reinforced rib 11.Crumple reinforced rib 11 is stratiform setting along the pipe range direction of energy-absorbing pipe fitting 10 on the tube wall of energy-absorbing pipe fitting 10, and the crumple reinforced rib 11 of same layer is along the circumferentially evenly interval setting of pipe fitting, and the crumple reinforced rib 11 of adjacent layer is staggered layout.Energy-absorbing pipe fitting 10 is to be welded after two identical involutory overlap joints of grooved plate 10a, the structure of grooved plate 10a as shown in Figure 2, two identical grooved plate 10a notches of structure are placed relatively and along the dislocation of groove width direction, it is the alternately overlap joint of cell wall of grooved plate 10a, as shown in Figure 4, grooved plate 10a cell wall bonded to each other is welding edge to concrete overlapping mode.Existing energy-absorbing pipe fitting more than 10 is combined by two different plates of structure, often there will be the phenomenon that misplaces part when assembling, very easily causes scrapping of product, and assembling difficulty is large, and productive costs is high.And the structure of grooved plate 10a in the application is identical, so can avoid misplacing the phenomenon of part, when reducing assembling difficulty, also reduce productive costs.
While offering vehicle paintwork electrophoresis on the tube wall of energy-absorbing pipe fitting 10, flow into and flow out the through hole 12 of energy-absorbing pipe fitting 10 tube chambers for electrophoresis liquid.Through hole 12 can play the role of positioning in the time that the involutory overlap joint of two grooved plate 10a is welded, and enters the effect that can play liquid-leaking nozzle after painting electrophoresis, makes the electrophoresis liquid can circulate, has guaranteed electrophoretic effects, the risk of having avoided energy-absorption box inner chamber easily to get rusty.Grooved plate 10a landing edge place adopts spot welding to connect, and than freezing, form quality of connection is more reliable, and Joint strenght is higher.When use, be connected with front guarantor's crossbeam with the less one end of cross-sectional plane, be connected with front stringpiece of vehicle body 20 front ends with the larger one end of cross-sectional plane, as shown in Figure 3.Can adjust according to actual needs the length of energy-absorbing pipe fitting 10, and can suitably increase and decrease crumple reinforced rib 11 numbers simultaneously and adjust crumple reinforced rib 11 shapes.
