Description
Technical field
This utility model relates to a kind of buffer unit, a kind of for vehicle bumper, utilizes the buffer unit of pivot plate.
Background technology
Generally, automobile or other vehicles are both provided with bumper, during so that automobile collides with automobile or other barriers, the bumper arranged before and after automobile is by absorbing and buffering foreign impacts power, the safety of protection vehicle body front and rear part, thus reduces personnel and the injury of vehicle when high-speed impact.In general, by arranging padded coaming between bumper and vehicle body, when bumper is impacted, by impulsive force being shifted to vehicle body, thus during the bumper interphase interaction with vehicle body, padded coaming deformation is to reach to absorb and the effect of buffering.
As disclosed a kind of bumper in Chinese patent CN104742838A, it includes vehicle body and the bumper being installed on vehicle body, bumper is cushioning effect in collision, this bumper includes front thick stick, this bumper also includes the Buffer Unit that at least two relative tilt is arranged, this each Buffer Unit includes that elastic component is fixed the articulated part being connected and fixes, with this elastic component other end, the connecting rod being connected with this elastic component one end, this articulated part is for being articulated with this vehicle body, and this connecting rod is away from one end of elastic component and this front thick stick pivot joint.But although this bumper can play a role in the case of colliding when low cruise well, limited when speed per hour buffer capacity of Buffer Unit self as padded coaming when more than more than 30km/h, and the Buffer Unit connecting rod-type is the most damaged, cushioning effect more cannot be realized.
Chinese patent CN103978943A and for example discloses a kind of elastomeric composition bumper, including: plastic shell, anti-collision beam and helical spring, described plastic shell is arranged on the front of anti-collision beam, described helical spring is connected between plastic shell and anti-collision beam, several positioning sleeve it is provided with on described anti-collision beam, the end of described positioning sleeve is respectively arranged with hole, location, and the inner side of described plastic shell is provided with several guide post, and the front end of described guide post is separately positioned on inside hole, location.By the way, by the toughness of plastic shell itself plus the shock-absorbing capacity of spring, in slight-scuffing, can effectively reduce the damage of pedestrian and vehicle, and anti-collision beam is it is also ensured that the intensity of structure.Although this kind of bumper has carried out reinforcement to a certain extent for guide post by the way of hole, location, and recognize the plastic deformation using plastic shell and spring to increase protective effect, but crash protection when being still limited to vehicle low cruise.But time actually due to motor vehicles and pedestrian impact, usually having taken up brake measure due to driver, the power on bumper that acts on usually less than can make the degree of the padded coaming deformation such as guide post so that this kind of bumper effectively can not provide protection for pedestrian.
Along with the development of control technology, car manufactures has been developed for carrying multiple sensors, such as touch sensor, radar, laser radar, optical pickocff etc. on onboard system, by the collision detected or predict between pedestrian.When onboard system when detection or when predicting the collision with pedestrian or will with pedestrian impact time, active activation or transfer some counter-measures to alleviate the collision that pedestrian is subject to.But such system needs complicated sensor and Mechatronic Systems to play a role, and its unfailing performance is still worth discussion.Most important, when its most unresolved inevitable collision occurs, the problem that protection is the most effectively provided.
