Abstract
The utility model discloses a car front bumper buffer, including front bumper body, preceding crashproof roof beam and buffer block, on the front side profile of buffer block and the inboard profile of front bumper body at least the percent 85 or more the region match closely the scarf joint together, the rear side profile of buffer block and preceding crashproof roof beam fixed connection. When the vehicle bumped with the pedestrian, the powerful impact force of vehicle, the powerful impact force that produces were suffered to pedestrian's shank during buffer block ability active absorption vehicle collision to reduce the vehicle to pedestrian's injury, protection pedestrian's safety improves whole car security performance.
Description
Technical field
This utility model relates to field of automobile, especially relates to a kind of automobile front beam buffer unit.
Background technology
Frontal crash of vehicles and side collision are modal two class vehicle accidents, and head-on crash accident causes casualties at most, the therefore emphasis of head-on crash Shi Ge automobile vendor impact test research.When head-on crash occurs for vehicle and pedestrian, the shank of pedestrian is subject to the impulsive force that vehicle is powerful, brings damage to pedestrian shank.The existing vehicle of existing market has all kinds of buffer unit, when automotive crash safety regulation is more and more stricter, by increasing buffer device for collision, the damage that pedestrian shank is caused by vehicle with pedestrian's head-on crash can be effectively reduced, reduce the injury that pedestrian is brought by vehicle to greatest extent, promote vehicle security energy.Some vehicles realize buffering collision at front bumper reload buffer block, owing to buffer block structure design is unreasonable, cause the desired value not reaching setting during test, it is impossible to effectively realize the protection to pedestrian shank.
Utility model content
This utility model is for the deficiencies in the prior art; technical problem to be solved is to provide a kind of automobile front beam buffer unit, when making vehicle and pedestrian that head-on crash to occur, effectively reduces the damage that pedestrian shank is caused by vehicle; the safety of protection pedestrian, increases vehicle security energy.
This utility model is to make above-mentioned technical problem be addressed by the following technical programs.
A kind of automobile front beam buffer unit, including front bumper body, front anti-collision beam and buffer stopper, together with the front side profile of buffer stopper is closely rabbeted with the inner side profile of front bumper body, the rear side profile of buffer stopper is fixing with front anti-collision beam to be connected.As vehicle and pedestrian collision, the shank of pedestrian suffers the impulsive force that vehicle is powerful, the powerful impulsive force that buffer stopper produces when can effectively absorb vehicle collision, thus reducing the vehicle injury to pedestrian, the safety of protection pedestrian, improves vehicle security energy.As collision CAE sunykatuib analysis, improving buffer block structure on prior art basis, in simulation pedestrian impact, acceleration is reduced to 160.59g by original 171.44g, has reached desired desired value 170g, and effect is obvious.
As preferably, the medial type Middle face horizontal direction of front bumper body being provided with convex tendon, the front side profile of buffer stopper offers groove close-fitting with described convex tendon.
As preferably, the profile lower end, front side of buffer stopper protrudes from front bumper body lower end.
As preferably, buffer stopper is integrally fixed by mounting bracket and front bumper body.
As preferably, uniform in the front side profile of buffer stopper it is provided with some projections.
As preferably, buffer stopper is EPP foamed material structure.
As preferably, the inner side profile area ratio of the contact surface area of the front side profile of buffer stopper and the inner side profile of front bumper body and front bumper body is be more than or equal to 85 percent.
The beneficial effects of the utility model:
1. simple in construction, parts are few, and processing technique difficulty is low.
2. easy for installation, occupy little space.
3. when vehicle, with pedestrian, head-on crash occurs, the damage that pedestrian shank is caused by vehicle can be effectively reduced, protect pedestrains safety.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
In figure: 1-front bumper body, 2-front anti-collision beam, 3-buffer stopper.
Detailed description of the invention
By the examples below and in conjunction with accompanying drawing this utility model is described in detail.
This utility model one automobile front beam buffer unit as shown in Figure 1, including front bumper body 1, front anti-collision beam 2 and buffer stopper 3, the front side profile of buffer stopper 3 matches together with closely interlocking with eight ten five in the inner side profile of front bumper body 1 at least percent area above, and the rear side profile of buffer stopper 3 is fixed with front anti-collision beam 2 and is connected.In order to strengthen the chimeric degree of buffer stopper 3 and front bumper body 1, may select and convex tendon is set in the medial type Middle face horizontal direction of front bumper body 1, the front side profile of buffer stopper 3 is offered groove close-fitting with described convex tendon.In order to strengthen buffering dynamics, increase the profile area of buffer stopper 3, make the profile lower end, front side of buffer stopper 3 protrude from front bumper body 1 lower end.Buffer stopper 3 can pass through mounting bracket and be integrally fixed with front bumper body 1.Buffer stopper 3 generally adopts EPP foamed material structure.Uniform in the front side profile of buffer stopper 3 some projections are set, are conducive to strengthening the elastic profile laminating degree between buffer stopper 3 and front bumper body 1.
This utility model is not limited to embodiments described above, front bumper body, the contour structures of front anti-collision beam and the connected mode with buffer stopper can also adopt the embodiment of other malformation that equivalence is replaced in the middle of the known technology or prior art that those skilled in the art are obtained in that, as long as belonging to technology of the present utility model design or spirit, the powerful impulsive force produced during by improving buffer block structure and reaching effectively to absorb vehicle collision, thus reducing vehicle, the embodiment for the purpose of the injury of pedestrian is all fallen within protection domain of the present utility model.
