Description
Technical field
The present invention relates to a kind of snubber assembly, especially a kind of for vehicle bumper, utilize the snubber assembly of pivot plate.
Background technology
Usually, automobile or other vehicles are all provided with collision bumper, so that when automobile and automobile or other obstacles collide, the collision bumper arranged before and after automobile is by absorbing and cushion the safety of foreign impacts power, protection vehicle body front and rear part, thus reduces the injury of personnel and vehicle when high-speed impact. In general, by arranging cushioning material between collision bumper and vehicle body, when collision bumper is subject to impacting, by surging force is shifted to vehicle body, thus in the process interacted between collision bumper and vehicle body, cushioning material distortion is to reach the effect absorbing and cushioning.
As disclosed a kind of bumper in Chinese patent CN104742838A, it collision bumper comprising vehicle body and being installed on vehicle body, collision bumper is shock absorption in collision, this collision bumper comprises front thick stick, this collision bumper also comprises the Buffer Unit that at least two relative tilts are arranged, this each Buffer Unit comprises the articulated part that elasticity part is fixedly connected with and the union lever being fixedly connected with this elasticity part the other end with this elasticity part one end, this articulated part is for being articulated with this vehicle body, and this union lever is away from one end of elasticity part and this front thick stick pivot joint. Can play a role well but although this kind of bumper collides when low cruise, when speed per hour is limited more than surge capability as the Buffer Unit of cushioning material self during more than 30km/h, and the Buffer Unit connecting rod-type is easily damaged, shock absorption more cannot be realized.
Chinese patent CN103978943A and for example discloses a kind of elasticity combined bumper, comprise: plastic shell, anti-collision beam and whisker, described plastic shell is arranged on the front of anti-collision beam, described whisker is connected between plastic shell and anti-collision beam, described anti-collision beam is provided with several locating sleeves, the end of described locating sleeve is respectively arranged with pilot hole, and the inner side of described plastic shell is provided with several tail rods, and the front end of described tail rod is separately positioned on pilot hole inside. By the way, the shock-absorbing capacity of spring is added by the toughness of plastic shell itself, in slight-scuffing, it is possible to effectively reduce the damage of pedestrian and vehicle, and anti-collision beam can also ensure the intensity of structure. Although this kind of collision bumper is by the carry out reinforcement to a certain extent of the mode of pilot hole for tail rod; and recognize and use the flexible distortion of plastic shell and spring to increase provide protection, but collision protection when being still confined to vehicle low cruise. But time in fact due to Motor vehicles and pedestrian impact, owing to driver has usually taked brake measure, the power on collision bumper that acts on usually is less than the degree of the distortion such as the cushioning material that can make tail rod so that this kind of collision bumper effectively can not provide protection for pedestrian.
Along with the development of control techniques, car manufactures has been developed and has been carried multiple sensors on onboard system, such as contact pickup, radar, lidar, optical sensing device etc., by the collision detected or predict between pedestrian. When onboard system when detect when predicting the collision with pedestrian or will with pedestrian impact time, active activation or transfer the collision that some counter-measures are subject to alleviate pedestrian. But such system needs complicated sensor and Mechatronic Systems to play a role, and its reliable performance is still worth discussion. The most important, how it effectively provides the problem protected when still unresolved collision unavoidably occurs.
Summary of the invention
The present invention provides a kind of technical scheme, has solved in prior art at least one technical problem existed.
The present invention provides a kind of snubber assembly, comprises collision bumper whippletree, and described collision bumper whippletree is attached on vehicle frame by bumper coupling parts, and can relative to longitudinal relative movement of described vehicle frame; It is characterized in that: described bumper coupling parts comprises support bar and the pivot plate of longitudinally extension, wherein said collision bumper whippletree attaches to one end of described support bar, the other end of described support bar by the first rotating shaft can pivotable be connected to pivot plate, described pivot plate and buffer rack are by the connection of the 2nd rotating shaft energy pivotable simultaneously; Described pivot plate can rotate relative to described buffer rack in predetermined angular.
Preferably, the upper side wall of described buffer rack has uncovered groove, and the lower wall of described buffer rack has perforated slot, and described uncovered groove and described perforated slot are suitable for the both ends card with described pivot plate and close.
Preferably, it is provided with back up pad in the end of described vehicle frame, described back up pad is longitudinally being extended with whisker along described vehicle frame, it is provided with transverse wall in the middle part of described buffer rack, described transverse wall inside is provided with permanent magnet, the inner side of described collision bumper whippletree be attached with the magnetic pole of the permanent magnet with described transverse wall inside contrary permanent magnet dividing plate.
