Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
Fig. 1 is the schematic diagram of the buffer structure reducing Pedestrian Lower Leg Injury of an embodiment of the present utility model.This buffer structure is the plastic. buffer body of a strip, and it includes energy-absorbing main panel 1 and the first limiting plate the 21, second limiting plate 22 and the gripper shoe 23 being positioned on energy-absorbing main panel 1.In an embodiment of the present utility model, this buffer structure is installed on front beam.First limiting plate 21, second limiting plate 22 and gripper shoe 23 extend to form to the direction towards front beam by energy-absorbing main panel 1, first limiting plate 21, second limiting plate 22 and gripper shoe 23 are almost parallel, and arrange from bottom to top along the short transverse of energy-absorbing main panel 1, energy-absorbing main panel 1, it is formed with the first cushion space 11 between first limiting plate 21 and the second limiting plate 22, energy-absorbing main panel 1, the second cushion space 12 it is formed with between second limiting plate 22 and gripper shoe 23, the height of the first cushion space 11 and the second cushion space 12 is roughly equal, namely the distance between the first limiting plate 21 and the second limiting plate 22 is substantially equal to the distance between the second limiting plate 22 and gripper shoe 23.First limiting plate 21 and the second limiting plate 22 are used for fixing buffer structure, and gripper shoe 23 is unsettled setting after buffer structure installs.
Refer to Fig. 2; the panel moulding of energy-absorbing main panel 1 is consistent with the moulding of automobile front beam and is fitted in inside front bumper eyelid covering, to improve the rigidity of front bumper, absorbs the main energetic of lower leg crash; knee time simultaneously for lower leg crash provides and supports, and shields.
First limiting plate the 21, second limiting plate 22 laminating is fixed on two end faces up and down of front beam, for limiting the vertically movable of this buffer structure.In an embodiment of the present utility model, first limiting plate the 21, second limiting plate 22 is provided with 12 boss 24 protruded to the first cushion space 11, these boss 24 intervals are arranged, and these boss 24 are respectively provided with an installing hole 3, when buffer structure assembles, first limiting plate the 21, second limiting plate 22 is fixed on front beam by the buckle formed by boss 24, thus fixing this buffer structure.Certainly in other embodiments, it is also possible to boss 24 and the installing hole 3 of other numbers be set or boss 24 and installing hole 3 are only located therein on a limiting plate, or by other fixed forms, this buffer structure being fixed on front beam.In an embodiment of the present utility model, part at the close energy-absorbing main panel 1 of the first limiting plate 21 offers multiple reduction hole 5, these weaken hole 5 and mutually stagger with boss 24, namely weaken hole 5 and be arranged on the position being not provided with boss 24 on the first limiting plate 21, so, carry out local weakness when integral rigidity is big by reduction hole 5, be so more conducive to collapse energy-absorption.Can certainly only on the second limiting plate 22 simultaneously or reduction hole 5 is set on the first limiting plate 21 and the second limiting plate 22.In an embodiment of the present utility model, buffer structure also includes multiple reinforcement 4, and these reinforcements 4 include six the first reinforcements 41 being located in the first cushion space 11 and nine the second reinforcements 42 being located in the second cushion space 12.These six the first reinforcements 41 separate certain interval in the first cushion space 11 and uniformly erect, and are connected with first limiting plate the 21, second limiting plate 22 and energy-absorbing main panel 1.These nine the second reinforcements 41 separate certain interval in the second cushion space 12 and uniformly erect, and are connected with the second limiting plate 22, gripper shoe 23 and energy-absorbing main panel 1.In order to be more beneficial for collapse energy-absorption and protect shank knee; the width of the first reinforcement 41, less than the width of the second reinforcement 42, is positioned at the width width less than the second reinforcement 42 being positioned at the second cushion space 12 two ends of the second middle reinforcement 42 of the second cushion space 12.Specifically, the width of the first reinforcement 41 is 30mm, primarily serves the purpose of collapse energy-absorption；The width being positioned at seven the second reinforcements 42 in the middle of the second cushion space 12 is 35mm, and the width of the first reinforcement 41 being positioned at the second cushion space 12 two ends is 60mm, primarily serves the purpose of support shank knee.The number in reinforcement 4 and size in the present embodiment are not used to limit this utility model, the first reinforcement 41 or the second reinforcement 42 can also be provided only with simultaneously, or the width that will be located in the first reinforcement 41 in the middle of the first cushion space 11 is set smaller than being positioned at the width of first reinforcement 41 at the first cushion space 11 two ends.
In an embodiment of the present utility model, described buffer structure is to be made of plastics, and by adopting plastic material, it is prone to one-body molded；Quality is lighter；Relatively foam buffer stopper, reduces the requirement in energy-absorbing space；This utility model is not limited to cover position, front beam front end simultaneously, it is possible to cover whole bumper even cell structure.
Below its operation principle is described in detail.
When people's car collides; impact on lower legs automotive front end; collision impact is then communicated to buffer structure; elastic deformation even plastic deformation can be there is in the first reinforcement 41 and energy-absorbing main panel 1 on collision course; slow down lower leg crash speed, thus the energy of absorbing impact on lower legs, and the hole 5 of weakening arranged is more conducive to collapse energy-absorption when colliding; second reinforcement 42 also can well support knee location, protects knee ligament.
In sum, this utility model is by increasing the height of energy-absorbing main panel, it is internally formed two cushion spaces at buffer structure, thus increasing cushion area, can under the premise of front beam to front guarantor's eyelid covering energy-absorbing insufficient space (if energy-absorbing space is less than 60mm), also the injury values requirement of pedestrian shank collision can be met, and, the second cushion space owing to being additionally formed on the first cushion space top can well support knee location, protection knee ligament, buffer structure of the present utility model is made to be more conducive to protection pedestrian lower leg, reduce shank collision injury values.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
