Abstract
The utility model discloses a pedestrian protection device used for vehicles, which comprises an upper buffer bar (1) and a lower buffer bar (2), wherein the upper buffer bar (1) and the lower buffer bar (2) are arranged on the inner side of a front buffer bar of a vehicle and are connected through a connecting element (3), both ends and the middle of the upper buffer bar (1) and the lower buffer bar (2) are all provided with a crossed net structure (4), both of the buffer bar (1) and the lower buffer bar (2) are formed by one-step molding and are parallelly arranged in different planes, and one side of the lower buffer bar (2) opposite to the front buffer bar of the vertical is supported by a support frame. The pedestrian protection device with the structure changes the contact of the single front buffer bar of the vehicle by the pedestrian into the contact of the upper buffer bar and the lower buffer bar, the contact area of small legs and the buffer bars is enlarged, the impact is averagely distributed, and the injury degree of the impact on the legs is reduced.
Description
Technical field
The utility model relates to a kind of pedestrian protection, especially relates to a kind of pedestrian protection that is installed on the vehicle front bumper inboard.
Background technology
In recent years, national governments and automaker more and more pay attention to the protective value of automobile to the pedestrian, the degree that the pedestrian is hurt when taking place to reduce traffic accident.When the pedestrian takeoffs with the vehicle collision of travelling, collision once more will take place in the pedestrian with the upper surface of vehicle front body structure, and therefore, shank very easily causes than major injury.Therefore, the device that needs protection drops to minimum with injury.
Following document discloses the fender guard to the pedestrian, as: the patent No. is that the patent documentation of ZL 200710041605.5 discloses " bumper pedestrian protecting equipment special-purpose for automobile bumper ", comprising: this fender guard is installed in the front bumper assembly bottom of automobile by support, the employing thin material is made, be hollow structure in the U type, the angle of support is downward-sloping 13 ° of space; The patent No. is that the patent documentation of ZL200710109114.X discloses " pedestrian protection that is used for vehicle ", this fender guard is arranged in the vehicle front side bottom, plate-like piece along the fore-and-aft direction of vehicle extends comprises front and rear, and reinforced rib is arranged in certain sequence on the plate; The patent No. is that the patent documentation of ZL02821946.5 discloses a kind of " vehicle head structure of automobile ", and a spill anticollision box is installed on headstock, and between fill in foam, and absorb collision energy, to reach protection vehicle and pedestrian's purpose.
Yet, the disclosed pedestrian protection of above-mentioned patent documentation all has all defectives that is difficult to overcome, as: patent documentation 1 disclosed pedestrian protection is a hollow structure in the U type, and U type cross-sectional plane is also unstable, and the angle of support is the space and does not also have practicality for downward-sloping 13 °; Patent documentation 2 disclosed pedestrian protections need a large amount of assemblies, and demand space is big, complex manufacturing technology, and the cost of assembly is higher, installs also pretty troublesome; The complex structure of anticollision box in the patent documentation 3 needs the longitudinal extension sheet metal component to be located, and the space that needs is bigger, is not suitable for the less vehicle of front space, and poor for applicability, only is fit to indivedual vehicles, and difficulty is installed, and is unfavorable for the NVH performance of car load.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of pedestrian protection that is used for vehicle at problems of the prior art; its objective is by when vehicle and pedestrian bump, reducing the acceleration peak value of pedestrian's shank; reduce the angle of bend of shank, thereby played good protective effect the pedestrian.
The technical solution of the utility model is that this a kind of pedestrian protection that is used for vehicle comprises insure thick stick and the following bumper/spoiler that is installed in the vehicle front bumper inboard, and insuring links together by attaching parts between thick stick and the following bumper/spoiler.
Described two ends and middle part of insuring thick stick and following bumper/spoiler is equipped with the cross network structure that is used to absorb impact energy.
The described thick stick of insuring all adopts single injection-molded with following bumper/spoiler, and parallel being arranged in the different planes.
A described bumper/spoiler side relative with vehicle front bumper down passed through stent support.
A kind of pedestrian protection that is used for vehicle with above-mentioned special construction has the following advantages:
1, this kind pedestrian protection contacts with vehicle front bumper by original pedestrian is single, becomes with bumper/spoiler up and down to contact, and has increased the area of contact of shank and bumper/spoiler, and the mean allocation impact load has reduced the extent of injury that impacts shank.
2, the cross network structure of arranging on this kind pedestrian protection bumper/spoiler; impact energy can be cushioned, reach the purpose that reduces the shank acceleration peak value, stop the shank bottom further to travel forward simultaneously; reduce the angle of bend of shank, reach the purpose of protection pedestrian lower leg.
3, this pedestrian protection moulding is simple, light, and demand space is less, is fit to multiple vehicle and uses.
