Abstract
The utility model relates to a leg collision-prevented energy-absorbing device at the front of an automobile, comprising a front collision surface and upper and lower collision surfaces, the upper and lower collision surfaces are respectively located at both sides of the front collision surface and integrated with the front collision surface, the upper and lower collision surfaces are provided with reinforced ribs, the upper collision surface and the lower collision surface are mutually parallel and are perpendicular to the front collision surface. The leg collision-prevented energy-absorbing device, when the automobile is impacted from the right side, can effectively absorb the collision energy and can reduce the damage of the collision to the leg.
Description
Technical field
The utility model relates to a kind of automobile component, particularly is welded on the anti-shank collision energy-absorbing device of automotive front on the preceding crashproof crossbeam of automobile.
Background technology
Be provided with front bumper and preceding crashproof crossbeam in the front portion of automobile, also be welded with anti-shank collision energy-absorbing device on preceding crashproof crossbeam, it is between front bumper and preceding crashproof crossbeam.This energy absorption device must have deformability preferably, to absorb collision energy, alleviates by rammer's injury, can guarantee that the crash structure of automobile has enough deformation spaces simultaneously.Existing anti-shank collision energy-absorbing device mostly is metal sheet gold part greatly, form by preceding impingement area and the upper and lower impingement area that is connected in these preceding impingement area both sides, have certain included angle between upper and lower impingement area and the preceding impingement area, make the cross-sectional plane of this energy absorption device be the trapezium structure that does not have the base.Upper and lower impingement area is provided with reinforced rib, and reinforced rib keeps at a certain distance away and is arranged on the whole upper and lower impingement area, and with preceding impingement area edge-perpendicular, reinforced rib is a strip shape, its bottom surface is an arcwall face.Anti-shank collision energy-absorbing device is welded on before the automobile on the crashproof crossbeam (as shown in Figure 3) by upper and lower impingement area.
This kind structure of existing anti-shank collision energy-absorbing device is when head-on crash takes place in automobile and pedestrian, the suffered lateral impact power of the preceding impingement area of energy absorption device will resolve into less component and be passed to upper and lower impingement area, this component is difficult to make upper and lower impingement area to produce distortion, thereby make upper and lower impingement area can not dissolve, absorb the energy that above-mentioned horizontal impact force produces preferably, whole so anti-shank collision energy-absorbing device just can not better realize being out of shape energy-absorbing, thereby will cause than major injury the knocked's shank.And, owing to be covered with reinforced rib on the upper and lower impingement area of existing anti-shank collision energy-absorbing device, the bottom surface of these reinforced ribs is an arcwall face, this will make the compression stiffness of upper and lower impingement area excessive, upper and lower impingement area is not easy to produce distortion when the component of the horizontal impact force that is subjected to transmitting from preceding impingement area, this also will cause anti-shank collision energy-absorbing device to be not easy to be out of shape energy-absorbing, thereby when Vehicular impact human body shank, will cause than major injury the human body shank.
The utility model content
The purpose of this utility model provides the anti-shank collision energy-absorbing device of a kind of automotive front, makes it easily produce distortion when automobile is subjected to positive bump, with effective absorption collision energy.
Automotive front described in the utility model is prevented the shank collision energy-absorbing device, constitute by preceding impingement area and upper and lower impingement area, upper and lower impingement area lays respectively at preceding impingement area both sides, combine as a whole with preceding impingement area, upper and lower impingement area is provided with reinforced rib, and last impingement area is parallel to each other with following impingement area and is vertical with preceding impingement area.
Described reinforced rib is positioned at the two ends of upper and lower impingement area.
The bottom surface of described reinforced rib is the plane.
The anti-shank collision energy-absorbing device of this automotive front is parallel to each other owing to its upper and lower impingement area and is vertical with preceding impingement area, its cross-sectional plane is has lacked rectangular configuration on one side, when current impingement area is subjected to lateral impact power, upper and lower impingement area be subjected to force direction consistent with it, can not produce component, so more be easy to generate compressive deformation with respect to existing anti-shank collision energy-absorbing device structure; And because the reinforced rib that is provided with on the upper and lower impingement area only is distributed in the two ends of upper and lower impingement area, the bottom surface of reinforced rib is the plane, this also makes this anti-shank collision energy-absorbing device more be easy to generate compressive deformation than existing structure, thereby make the utility model when automobile is subjected to positive bump, can effectively absorb collision energy, reduce to collide injury the human body shank.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the block diagram of the anti-shank collision energy-absorbing device of automotive front described in the utility model;
Fig. 2 is the cross-sectional plane enlarged drawing of the reinforced rib on the upper and lower impingement area;
Fig. 3 is the welded condition scheme drawing of crashproof crossbeam before this anti-shank collision energy-absorbing device and the automobile.
The specific embodiment
As shown in Figure 1, the anti-shank collision energy-absorbing device of this automotive front is made of preceding impingement area 3 and upper and lower impingement area 1,4, upper and lower impingement area 1,4 lays respectively at preceding impingement area 3 both sides, combine as a whole with preceding impingement area 3, last impingement area 1 is parallel to each other with following impingement area 4 and is vertical with preceding impingement area 3, the cross-sectional plane of this anti-shank collision energy-absorbing device is has lacked rectangular configuration on one side.
As shown in Figure 2, upper and lower impingement area 1,4 is provided with the reinforced rib 2 with preceding impingement area 3 edge-perpendicular, and it keeps at a certain distance away and is arranged in the two ends of upper and lower impingement area 1,4, and the bottom surface 5 of reinforced rib 2 is the plane.
As shown in Figure 3, the anti-shank collision energy-absorbing device 6 of this automotive front is welded on before the automobile on the crashproof crossbeam 7 by upper and lower impingement area 1,4.
Claims (3)
