Abstract
The utility model provides a car anticollision girder steel, including base, energy -absorbing buffering box and girder, the fixed welding in girder both ends has an energy -absorbing buffering box, energy -absorbing buffering box with the base welding, the base is connected with car automobile body girder, and energy -absorbing buffering box is two -sided fold -type, and the girder is a mouthful style of calligraphy structure. The utility model provides an energy -absorbing is efficient, the good car anticollision girder steel of resistance performance.
Description
Technical field
The utility model relates to automotive field, particularly a kind of automobile collision preventing girder steel.
Background technology
The vehicle frame afterbody of most of vehicle of China uses the crashproof girder steel of foam or plasthetics making, softer and crisp, lack impact resistance and buffer capacity, the protective action of actv. is not possessed when rear-end collision, automobile tail can be made seriously impaired once collide, its service expenditure is strengthened, and the life security of rear row passenger when certain seriously knocks into the back, can be endangered.
Utility model content
The technical problems to be solved in the utility model will provide a kind of can possess impact resistance and the strong automobile collision preventing girder steel of buffer capacity.
To achieve these goals, the technical solution adopted in the utility model is, a kind of automobile collision preventing girder steel, it is characterized in that, comprise base, energy-absorbing buffering box and girder, girder two ends are fixedly welded with energy-absorbing buffering box, are connected bottom energy-absorbing buffering box with base, base is connected with car body crossbeam, and described energy-absorbing buffering box is two-sided fold-type.So more effectively can absorb the kinetic energy that collision produces.
In some embodiments, described girder is the hollow structure of side ports font.Larger intensity can be produced thus to resist impact force.
In some embodiments, the material of described girder is metal material.The crashproof ability of automobile can be strengthened by actv. thus.
In some embodiments, described girder is provided with foam buffer zone.The effect alleviating impact force can be played thus.
In some embodiments, described base and car body crossbeam are removably connected by screw.Thus can the crashproof girder steel of more convenient replacing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of a kind of automobile buffer beam of the utility model;
Fig. 2 is the structural representation of the another kind of embodiment of a kind of automobile buffer beam of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 show schematically show a kind of automobile buffer beam of the present utility model, comprise base 1, energy-absorbing buffering box 2 and girder 3, girder 3 two ends are fixedly welded with energy-absorbing buffering box 2, the top of energy-absorbing buffering box 2 is connected with girder 3, bottom is connected with base 1, base 1 is connected with car body crossbeam, and its effect is that automobile buffer beam is arranged on automobile.Relative to car body outwardly, its radian can adjust according to the radian of car body crossbeam girder 3.Automobile buffer beam can be separately positioned on car body crossbeam front and back position; when car body is knocked into the back or is knocked into the back; collision can be born the very first time and resist the impact force be subject to; to reduce the impulsive force suffered by car body; protect the safety of car body and complete to greatest extent, play the effect of the safety of protection passenger.
Energy-absorbing buffering box 2 is two-sided fold-type, namely two faces that the side of energy-absorbing buffering box is wherein relative are fold-type, energy-absorbing buffering box 2 is arranged between car body crossbeam and girder 3, its effect is when automobile is when being collided power, the crumple process of plastic deformation can be produced, play the effect absorbing and collide impact force and the energy produced, alleviate the dynamics of collision, reduce the injury that rear-end impact produces automobile.But the energy-absorption box of plane is not easy directly to deform in stressed, the kinetic energy absorbed is limited, with the energy-absorption box of two-sided fold, crumple can be there is respectively, can better one-level level crumple be out of shape stressed time, absorbing forces of impact in the process of distortion crumple, therefore onesize energy-absorption box, two-sided fold-type energy-absorbing buffering box 2 can absorptance plane the more kinetic energy of energy-absorbing buffering box 2 thus energy-absorbing buffering box 2 is set to two-sided fold-type can the more efficiently absorption car body impact force of bearing, the more efficiently injury reducing collision and automobile is produced.
As shown in Figure 1, described girder 3 is hollow structure.Namely side is the hollow-pole charge structure of mouthful word; be characterized in being 4 force structures; can a bit suffered impact of multidirectional dispersion automobile; the intensity of the power suffered by a point can be reduced to greatest extent; larger intensity can be produced to resist impact force; reduce impact to greatest extent to the infringement of vehicle body, more effectively protect the complete of car body.
The material of described girder 3 is metal material, is mainly aluminum alloy or steel.Aluminum alloy density is low, but intensity ratio is higher, close to or exceed high-quality steel, plasticity is good, can be processed into various section bar, has excellent electric conductivity, permeability of heat and non-corrodibility, industrially widely uses, and use amount is only second to steel.Some aluminum alloys can adopt heat treatment to obtain good mechanical characteristics, physical property and corrosion resistance; Steel is the iron carbon of carbon content between 0.0218%-2.11%, is characterized in that tensile strength is high, modulus of elasticity is strong, plasticity and dynamic ductility is strong, hardness is high, and its impact strength and toughness are far superior to aluminum alloy.Therefore adopt the girder 3 made of metal material, be characterized in that intensity is high, hardness is large, can strengthen the crashproof ability of automobile by actv., can more effective protection automotive frame rear-end collision or when being knocked into the back, and reduces service expenditure.The material of girder can be selected according to the design requirement of car body.In some vehicle, foam or plasthetics also can be used to make, and its shortcoming is softer and crisp, does not possess actv. protective action when automobile generation rear crash event.
As shown in Figure 2, girder 3 arranged outside has foam buffer zone 4.Namely the soft foam of one deck is increased in the outside of girder 3; object is the space in order to increase buffering; add foam buffer zone 4; not only when the low speed collision of below 4km/h, an effect supported can be played to girder 3, alleviates the effect of impact force; reduce the damage of collision to Federal bumper; reduce maintenance cost, in certain degree, protection ratio can also be hit object, the safety of such as pedestrian compared with weak tendency.
Four angles of base 1 and car body crossbeam two ends are all provided with equal-sized circular hole, base 1 and car body crossbeam use screw and nut to removably connect by circular hole, so arranging can the automobile buffer beam that breaks of more convenient replacing, makes maintenance process more convenient.
