Description
Technical field
The present invention relates to a kind of fender guard, be used for after particularly relating to automobile and roadside pedestrian impact protecting pedestrian shank position to escape injury or reducing the anti-collision device for automobile of 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 is no longer confined to protect the passenger in car; but expand the pedestrian collided with automobile to; when automobile and pedestrian collision; usually be all vehicle body directly and pedestrian shank portion come in contact, thus pedestrian shank portion directly to be damaged.Be difficult to the requirement meeting GB GB/T 24550-2009.
It can thus be appreciated that when automobile and pedestrian collision, the shank of pedestrian will come to harm at first, and the degree of injury of pedestrian shank also by have influence on further cannot stand because shank is injured or fall after further injury to pedestrian.
And in prior art, the safe design of automobile is consider safely for the protection of passenger inside the vehicle mostly, seldom consider that the safety of rear pedestrian 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 protecting pedestrian shank, and when head-on crash occurs for automobile and pedestrian, this device can effectively be avoided or reduce owing to colliding the injury caused pedestrian shank position.
Its technical matters to be solved can be implemented by the following technical programs.
A kind of anti-collision device for automobile protecting pedestrian shank; this anti-collision device for automobile beam structure in protrude overall relative to car body; this beam structure is made up of the connecting portion of connection body of being used for of the energy-absorbing portion in outside, middle rib and inner side, and this beam structure is connected and fixed on the front end of automobile accessory frame and the top of deflecting plate through described connecting portion.
As the further improvement of the technical program, the center of gravity position of calf shank when the spatial altitude of described beam structure is not walked higher than pedestrian, such as this center of gravity terrain clearance is 276mm.
As the further improvement of the technical program, the lower surface distance ground 15 ~ 40cm of described beam structure.
As one of the preferred embodiments of the present invention, the lower surface distance ground 40cm of described beam structure.
Also as the further improvement of the technical program, described energy-absorbing portion entirety is in banded, and its banded inside forms multiple buffering energy-absorbing space through the segmentation of multiple " * " type gusset.
Wherein, the bandwidth in described banded energy-absorbing portion is 40 ~ 50mm, preferred 50mm.
Also as the further improvement of the technical program, the longitudinal profile undulate structure of described rib.
Further, be large wave structure with described wavy shaped configuration, form the less rips structure of peak value at the crest/trough of the described large wave structure of part.
In addition, rib also comprises the crest connecting described large wave structure and is connected gusset with trough and the described crest of rips structure with the longitudinal direction of trough.
Again as the further improvement of the technical program, described connecting portion is provided with mounting-positioning holes, and the surrounding of described mounting-positioning holes is provided with knock hole reinforced rib.
In addition, can also leaking hole be provided with at each trough place of each large wave structure described, accumulate wherein to prevent rainwater.
Adopt the anti-collision device for automobile of the protection pedestrian shank of technique scheme; by arranging an outstanding crossbeam operator guards in the relevant position of automotive front; and utilize the buffering crumple in the banded energy-absorbing portion of this structure front end to carry out suitable protection to the pedestrian of collision rift, thus the injury that reduction traffic accident causes pedestrian.

Detailed description of the invention
The object of the invention is to propose a kind of city SUV pedestrian protection that can reduce the injury of pedestrian shank portion.
As shown in Figures 1 to 4, this anti-collision device for automobile main body is a crashproof girder structure, and the front end (outside) of shank collision prevention girders 2 is the energy-absorbing region 3 of a band shape.Because position of collision when pedestrian and vehicle collision is below pedestrian shank shin bone center of gravity.Thus the lower end terrain clearance of shank collision prevention girders 2 is set to 15 to 40 centimetres (preferably 40 centimetres).
Become the energy-absorbing band of " * " type structure in shank collision prevention girders front end, the inside of energy-absorbing band forms the energy-absorbing buffering region of multiple hollow by the segmentation of multiple " * " type gusset 31, and several " * " font structures are equidistant is one by one distributed in reinforcement structure front end.Make there is certain crumple function when colliding, its shrinkable region is (i.e. the width in energy-absorbing region be 40 arrive 50mm, preferred 50mm) between 40mm to 50mm.Because shank collision prevention girders mainly plays support pedestrian shank, prevent pedestrian in collision process 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 compared with other structural advantages, and its intensity can meet the function supporting shank in collision.
In the reinforcement structure that the banded endergonic structure rear end of " * " type is the similar wavelike structure of not shrinkable, with reference to Fig. 4 middle section figure; Its longitudinal cross-section is waveform, and wave structure 4 to be separated by distribution by large wave 41 and rips 42 liang of types, wherein defines this rips 42 at 412, the trough of large wave 41; Large rips interval, the centre of longitudinally two large wave structures of wave structure is by a waling 43 thus the crest 412 of the crest 411 of large wave, trough 412 and rips and trough are linked together.The wave structure 4 being arranged on shank collision prevention girders 2 rear end is the mode in order to improve shank collision prevention girders, the mode of shank collision prevention girders can be improved, again can in collision process, " * " word structure of front end energy-absorbing first produces crumple function, absorb a part of shank collision energy, when after crumple to the reinforcement structure of rear end, the no longer crumple of shank collision prevention girders, support shank, prevent pedestrian from piercing bottom of car.Thus pedestrian is toppled over to automobile steering, which reduces the angle of bend of shank.
There is a leaking hole 44 at trough 412 place of each large wave, pile up to prevent rainwater.
Mounting structure is in the rear end strengthening structure, strengthens structure is fixed on automobile accessory frame 1 front end by erecting device, the top of deflecting plate.This mounting structure is mainly used to whole crossbeam to be connected with car body, and it mainly comprises mounting-positioning holes 5 and is arranged on the knock hole reinforced rib 51 around it.
The automobile anti-collision protective device of pedestrian shank of the present invention, its structure is simple, for the higher automobile in this kind of chassis of city SUV can actv. reduce collision time injury to pedestrian shank, improve the safety of automobile.
