Abstract
The present invention discloses one kind of pedestrian protecting unit attached to the front bumper of vehicle to minimize the injury of the pedestrian caused by collision. The pedestrian protecting unit mounted through a support below the front bumper is made of light material and has new structure. It can lower the collision height of the bumper, reduce the impact to the legs of the pedestrian and absorb collision energy through cooperation with the bumper.
Description
Technical field
The present invention relates to a kind of pedestrian protection, particularly a kind of pedestrian protection of automobile front beam special use.
Background technology
Now, along with the development of auto trade, automobile is more and more universal, and people also more and more pay attention to for the safety problem of automobile, are not only for the passenger in the car, also will protect the outer pedestrains safety of car simultaneously.
The vehicle collision guard technology also begins the important development direction of protection pedestrian security column for it; and existing automobile front beam is not provided with special proof equipment for the pedestrian; the pedestrian causes very big injury to the pedestrian easily after the collision that is subjected to automobile; shank when special very easily sustains damage.
Therefore, need especially a kind ofly fully the injury of pedestrian when being collided to be dropped to minimum, to protect the bumper pedestrian protecting equipment special-purpose for automobile bumper of pedestrains safety better.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of bumper pedestrian protecting equipment special-purpose for automobile bumper, when getting into an accident, farthest reduces to collide the degree of injury that causes to the pedestrian, protects pedestrains safety better.
Technical matters to be solved by this invention can be achieved through the following technical solutions:
A kind of bumper pedestrian protecting equipment special-purpose for automobile bumper is characterized in that, described pedestrian protection is installed in the bottom of the front bumper assembly of automobile by support.
Described support links to each other with pedestrian protection with front bumper assembly, and the angle of described support is downward-sloping 13 ° of space, by angle with rational distortion, reduces to clash into strength when pedestrian impact, thereby ensures that effectively pedestrian's knee, leg avoid grievous injury.
Described pedestrian protection adopts thin material to make, and it is a hollow structure in the U type, with the impact process of control to shank, reduces to clash into strength.
Be provided with reinforced rib at the front bumper assembly two ends, described reinforced rib is connected with described support, correctly is fixed on the described front bumper assembly to guarantee pedestrian protection.
Bumper pedestrian protecting equipment special-purpose for automobile bumper of the present invention; pedestrian protection adopts thin material and newly-designed structure; reduce the impact site height; with the impact process of control to shank; reduce to clash into strength; guarantee that simultaneously energy absorbing coordinates mutually with front bumper, thereby ensure that effectively pedestrian's knee, leg avoid grievous injury, realize purpose of the present invention.
Description of drawings
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is the contrast scheme drawing of the present invention and existing structure.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is an assembling scheme drawing of the present invention.
The specific embodiment
As Fig. 2, shown in Figure 3, a kind of bumper pedestrian protecting equipment special-purpose for automobile bumper, pedestrian protection 4 are installed in the bottom of the front bumper assembly 1 of automobile by support 2,3.
Support 2,3 links to each other with pedestrian protection 4 with front bumper assembly 1, and the angle of support 2,3 is downward-sloping 13 ° of space, by angle with rational distortion, reduces to clash into strength when pedestrian impact, thereby ensures that effectively pedestrian's knee, leg avoid grievous injury.
Be provided with reinforced rib 5,6 at front bumper assembly 1 two ends, reinforced rib 5,6 is connected with support 2,3 respectively, correctly is fixed on the front bumper assembly 1 to guarantee pedestrian protection 4.
According to the ISO11096 international standard, when bumping with the speed of 40km/h between the leg type of pedestrian's shank and the vehicle, maximum dynamic knee angle of bend must not surpass 21.0 °, and maximum dynamic knee shear displacemant must not surpass 6.0mm, and the measured acceleration/accel in shin bone upper end must not surpass 200g.
Generally when pedestrian and traveling automobile bump, it at first is bumper impact pedestrian's shank, shank is fractured, the engine case edge clashes into pedestrian's thigh then, be pedestrian's head and engine case collision at last, the collision of head is very easy to cause fatal harm to the pedestrian; Simultaneously, according to the difference of collision velocity, pedestrian's head also may bump with front windshield.
During collision, the pedestrian protection 4 on the front bumper assembly 1 contacts with the pedestrian, because pedestrian protection 4 is installed in the bottom of front bumper assembly 1, can effectively reduce the height with pedestrian impact, alleviates the wound that the pedestrian is subjected to; Simultaneously, when pedestrian protection 4 and pedestrian collided and contact, support 2,3 made pedestrian protection 4 can absorb the strength of bump effectively inwardly with the angle with rational bending, plays protection pedestrian's effect.
In the bumper pedestrian protecting equipment special-purpose for automobile bumper of the present invention; pedestrian protection 4 adopt flexible structures and reduce position of collision, and front bumper assembly 1 between reserve the method for buffer distance; be equivalent in vehicle body front structure, increase a crash energy absorption passage; can reduce injury; in order to avoid pedestrian lower leg is clashed into strongly; and scoop up the pedestrian, and fly once more to hit bonnet and front windshield, cause brain impaired.
More than show and described groundwork of the present invention and principal character and advantage thereof.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (3)
