Description
Technical field
The present invention relates to a kind of fender guard, relate in particular to the anti-collision device for automobile that is used for protecting pedestrian's calf position to escape injury behind automobile and the roadside pedestrian impact or reduces injury, belong to field of automobile.
Background technology
Along with the development of automotive technology and the raising of people's awareness of safety; the protection of automobile no longer is confined to protect the passenger in the car; but expand the pedestrian who bumps with automobile to; when automobile and pedestrian bump; usually all be vehicle body directly and pedestrian's calf come in contact, thereby pedestrian's calf is directly damaged.Be difficult to satisfy the requirement of GB GB/T 24550-2009.
Hence one can see that, and when automobile and pedestrian bump, pedestrian's shank will come to harm at first, and the degree of injury of pedestrian's shank also will further have influence on because the injured rear further injury to the pedestrian of can't standing or fall of shank.
And in the prior art, the safe design of automobile is to consider safely for the protection of passenger in the car mostly, considers that seldom rear pedestrian's safety occurs in collision.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of anti-collision device for automobile of the pedestrian's of protection shank, and when head-on crash occured for automobile and pedestrian, this device can effectively avoid or reduce because the injury that collision causes pedestrian's shank position.
Its technical matters to be solved can be implemented by the following technical programs.
A kind of anti-collision device for automobile of protecting pedestrian's shank; this anti-collision device for automobile is the beam structure of protrusion with respect to car body integral body; this beam structure is made of the energy-absorbing section in the outside, middle rib and the inboard connecting portion that is used for connection body, and this beam structure is connected and fixed on the top of front end and the deflecting plate of automobile accessory frame through described connecting portion.
As the further improvement of the technical program, the center of gravity position of calf shank that the spatial altitude of described beam structure is not higher than the pedestrian when walking, for example this center of gravity terrain clearance is 276mm.
As the further improvement of the technical program, the lower surface of described beam structure is apart from ground 15～40cm.
As one of the preferred embodiments of the present invention, the lower surface of described beam structure is apart from ground 40cm.
Also as the further improvement of the technical program, described energy-absorbing section integral body is banded, and form a plurality of buffering energy-absorbings space its banded inner cutting apart through a plurality of " * " type gusset.
Wherein, the bandwidth of described banded energy-absorbing section is 40～50mm, preferred 50mm.
Also as the further improvement of the technical program, the longitudinal profile undulate structure of described rib.
Further, take described wavy shaped configuration as large wave structure, form the less rips structure of peak value at the crest of the described large wave structure of part/trough.
In addition, rib also comprises the crest and the crest of trough and described rips structure and vertical gusset that is connected of trough that connects described large wave structure.
As the further improvement of the technical program, described connecting portion is provided with mounting-positioning holes again, is provided with the knock hole reinforced rib around the described mounting-positioning holes.
In addition, can also be provided with leaking hole at each trough place of described each large wave structure, to prevent the rainwater accumulation wherein.
Adopt the anti-collision device for automobile of the protection pedestrian shank of technique scheme; by the relevant position at automotive front an outstanding crossbeam protection structure is set; and utilize the buffering crumple of the banded energy-absorbing of this structure front end section that the pedestrian after colliding is carried out suitable protection, thereby reduce the injury that traffic accident causes the pedestrian.

The specific embodiment
The objective of the invention is to propose a kind of city SUV pedestrian protection that can reduce the injury of pedestrian's calf.
As shown in Figures 1 to 4, this anti-collision device for automobile main body is a crashproof girder structure, and the front end of shank collision prevention girders 2 (outside) is the energy-absorbing zone 3 of a band shape.Because the position of collision when pedestrian and vehicle collision is pedestrian's calf shank center of gravity below.Thereby the lower end terrain clearance of shank collision prevention girders 2 is set to 15 to 40 centimetres (preferred 40 centimetres).
Become the energy-absorbing band of " * " type structure at shank collision prevention girders front end, the inside of energy-absorbing band is regional by the energy-absorbing buffering that forms a plurality of hollows cutting apart of a plurality of " * " type gusset 31, and several " * " font structures are the equidistant reinforcement structure front end that is distributed in one by one.So that certain crumple function is arranged when collision, its shrinkable zone is (width that is the energy-absorbing zone is 40 to 50mm, preferred 50mm) between the 40mm to 50mm.Because mainly rising, the shank collision prevention girders supports pedestrian's shank, prevent that in collision process pedestrian from piercing the effect of bottom of car, therefore the endergonic structure intensity of front end can not be too low, " * " font structure is existing certain crumple than other structural advantages, and its intensity can satisfy the function that supports shank in the collision.
Be the reinforcement structure of the similar wavy structure of not shrinkable in the banded endergonic structure of " * " type rear end, with reference to Fig. 4 middle section figure; Its longitudinal cross-section is waveform, and wave structure 4 is by large wave 41 and 42 two types of distributions of being separated by of rips, and wherein 412 in trough at large wave 41 has formed this rips 42; Large rips interval, thus the centre of vertical two large wave structures of wave structure is linked together by crest 412 and the trough of a waling 43 with crest 411, trough 412 and the rips of large wave.The wave structure 4 that is arranged on shank collision prevention girders 2 rear ends is in order to improve the mode of shank collision prevention girders, can improve the mode of shank collision prevention girders, again can be in collision process, " * " word structure of front end energy-absorbing produces first the crumple function, absorb a part of shank collision energy, when crumple to the reinforcement structure of rear end, the no longer crumple of shank collision prevention girders, support shank, prevent that the pedestrian from piercing bottom of car.Thereby the pedestrian is toppled over to automobile steering, so just reduced the angle of bend of shank.
There is a leaking hole 44 at trough 412 places at each large wave, pile up to prevent rainwater.
Mounting structure is in the rear end of strengthening structure, strengthens structure is fixed in automobile accessory frame 1 by erecting device front end, the top of deflecting plate.This mounting structure is mainly used to whole crossbeam is connected with car body, and it mainly comprises mounting-positioning holes 5 and is arranged on its knock hole reinforced rib 51 on every side.
The automobile anti-collision protective device of pedestrian's shank of the present invention, it is simple in structure, when can actv. reducing collision for the higher automobile in this class chassis of city SUV to the injury of pedestrian's shank, the safety that improves automobile.
