Description
Technical field
The utility model relates to auto parts and components, especially relates to a kind of automobile buffer beam.
Background technology
Before and after automobile, collision prevention girders is one of important spare part ensureing automotive SBC energy.In high speed offset collision, impact on the left of vehicle body (or right side) can be delivered to right side (or left side) by actv. by collision prevention girders, allows whole car body go to absorb collision energy as far as possible.When low speed collision occurs (being generally below 15km/h), collision prevention girders can avoid impact to the infringement of longeron before and after vehicle body, reduces maintenance cost.The pattern of collision prevention girders can be related to its final intensity with thin and thick and material, and the intensity of collision prevention girders can not be too large, can not be too little, and intensity is too little does not have buffer action, and intensity is unfavorable for too greatly shock to be delivered to car whole body.The collision prevention girders of current most of car is all a monoblock steel plate, and it mainly plays rigid snubber effect, once be hit, has substantially just scrapped.Also some collision prevention girders arranges some dashpots, soft buffering can be played, such as: Chinese patent 201310677030.1 discloses a kind of front anticollision beam of automobile, comprise front anti-collision beam body, front anti-collision beam body comprises front end face and aft end face, and front end face and aft end face arrange dashpot respectively.It takes up space too large, and will greatly reduce can usage space in car.
Utility model content
The purpose of this utility model is: for prior art Problems existing, provides a kind of automobile buffer beam, solves existing collision prevention girders absorption collision energy effect undesirable, and the too large problem that takes up space.
The purpose of this utility model is achieved through the following technical solutions:
A kind of automobile buffer beam, it is characterized in that, this collision prevention girders comprises collision prevention girders housing, this collision prevention girders housing comprises end face outside and inner side end, the inside of collision prevention girders housing is divided into the first cavity, the second cavity and the 3rd cavity successively from end face outside to inner side end, load padded coaming in described first cavity, be provided with damper element in described second cavity, in described 3rd cavity, be provided with bumpar post.
Preferably, described padded coaming is plastics.
Preferably, described damper element is made up of four Metallic rod, and four Metallic rod connect to form " rhombus " structure, and two vertical angles ends of this damper element are separately fixed on the both sides inwall of the second cavity.
Preferably, institute's damper element is provided with multiple, and is covered with the second cavity.
Preferably, described bumpar post comprises many Metallic rod, and the two ends of every root Metallic rod are all separately fixed on the both sides inwall of the 3rd cavity.
Compared with prior art, the utility model has the following advantages:
1, be designed with three layers of buffering, can absorb collision energy step by step, assimilation effect is better;
2, three layers of buffering when collision energy is lower, can be absorbed by ground floor to hard by soft, to which floor cushions and causes damage, and then can not greatly reduce maintenance cost below;
3, every layer of buffering is all replaceable structure, even if run into strong collision, whole collision prevention girders also can not be caused all to scrap, and its bumpar post, damper element can carry out recycling.
Accompanying drawing explanation
Fig. 1 is external structure schematic diagram of the present utility model;
Fig. 2 is inner structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
The utility model provides a kind of automobile buffer beam, and as shown in Figure 1, this collision prevention girders comprises collision prevention girders housing, and this object profile can design according to actual needs.This collision prevention girders housing comprises end face outside B and inner side end A, and during installation, inner side end A installs towards vehicle body.As shown in Figure 2, it is divided into the first cavity 1, second cavity 2 and the 3rd cavity 3 successively to the inner structure of collision prevention girders housing from end face outside to inner side end.The through whole collision prevention girders of each cavity.Load padded coaming in first cavity 1, padded coaming can select the materials such as plastics, foam, rubber.Damper element 4 is provided with in second cavity 2.The damper element 4 of the present embodiment is made up of four Metallic rod, and four Metallic rod connect to form " rhombus " structure, and two vertical angles ends of this damper element are separately fixed on the both sides inwall of the second cavity 2.Damper element is provided with multiple, and is covered with the second cavity 2.Bumpar post 5 is provided with in 3rd cavity 3.Bumpar post comprises many Metallic rod, and the two ends of every root Metallic rod are all separately fixed on the both sides inwall of the 3rd cavity 3.The thickness of every layer of cavity can be selected as required, if second and third layer of cavity thickness increases, is then equivalent to the hardness adding whole collision prevention girders, if increase the thickness of first time cavity, is then equivalent to the flexibility adding collision prevention girders.
When the speed of a motor vehicle is higher, when there is strong collision, three cavitys can play three layers of buffer action, by soft to hard, significantly can absorb collision energy.Although whole collision prevention girders can deform after absorption collision energy, but the damper element inside collision prevention girders, bumpar post not necessarily all deformation occur, major part still can recycling, compared to conventional crash beam once there is deformation, then scrap for whole, greatly reduce service expenditure.
When the speed of a motor vehicle is lower, when there is slight impact, collision energy is directly absorbed by the first cavity, and owing to being elastomeric material in the first cavity, after impact pressure is cancelled, it recovers nature shape, without the need to changing.Nor damage can be caused to the parts in the second cavity, the 3rd cavity, thus maintenance cost is almost nil.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
