Abstract
The utility model relates to an automobile passive safety protection device, in particular to automobile front and rear safety beams made of carbon fiber composite materials and enhanced metal porous materials. On the premise of meeting the indexes of technological and economical performance that when an automobile encounters collision or tailgating in the running process at intermediate and high speed of 64-100 km/h, a driver and all passengers in the automobile are basically prevented from injuries and deaths, and the damage degree of the automobile is reduced, the front beam, the rear beam and a housing are made of the carbon fiber composite materials, the carbon fiber enhanced metal porous materials are used for making an energy absorber, the front and rear beams, the housing and the energy absorber are integrated through high-strength polymer binders, and therefore the front and rear safety beams which have combination of rigidity and flexibility and can efficiently buffer energy absorption are assembled. Compared with the prior art, the automobile front and rear safety beams have the advantages of being simple in structure, simplified in manufacturing process, low in weight, superior in performance than steel components, low in investment, and the like.
Description
Technical field
The utility model patent relates to vehicle passive safety fender guard technical field, is specifically related to the forward and backward safe beam of automobile of carbon fiber composite material and enhancing metal polyporous material.
background technology
The forward and backward safe beam of automobile (CN102582546A) of flexibility combined efficient buffering energy-absorbing is that one is applicable to that automobile is high, driving at moderate speed can substitute former bumper/spoiler (crossbeam or collision prevention girders), protection driver and conductor and substantially realize the product of the quantitative design of zero injures and deaths when bumping and knocking into the back; but all components such as the energy absorber of interior middle configuration, case, bottom girder are all to adopt common iron to make, keep off the user of manned vehicle for senior middle school without selecting alternative leeway.
Carbon fiber composite material and carbon fiber reinforced metal aerated materials, large owing to thering is stiffness-to-density ratio, strength-to-density ratio is high, energy absorption capacity is good, the excellent properties such as light specific gravity, be widely used in aerospace flight vehicle as structure and functional material, high speed train, automobile, the buffering energy-absorbing of the vehicle such as steamer and important building, in shock absorption device, making Federal bumper and energy absorber thereof also has the report of many documents and patent document, but all there are some defects, particularly quantitative design is made the vehicle passive safety fender guard that is suitable for travelling with 64～100km/h at express highway, having no other similarly reports.
Summary of the invention
The utility model patent object is on the CN102582546A patent basis proposing applicant, substitutes the forward and backward safe beam of automobile of common iron making with carbon fiber composite material and carbon fiber reinforced metal aerated materials, is development and the innovation of former patent.
The technical solution adopted in the utility model is: in the time meeting automobile and bump or knock into the back in the middle and high speed of 64～100 km/h is travelled, make all driver and conductors in car substantially avoid injures and deaths and alleviate under the technical and economic performance index prerequisite of automobile damage rate,
Select carbon fiber composite material to make forward and backward bottom girder and case, select carbon fiber reinforced metal aerated materials to make energy absorber, select high strength polymer binder that three assemblies are adhesive into one, be assembled into the forward and backward safe beam of flexibility combined efficient buffering energy-absorbing.
Compared with prior art, have the following advantages:
1, simple in structure, simplified manufacturing process, reduced investment;
2, weight saving is more than 50%, suitable with existing bumper/spoiler weight;
3, multiple lightweight energy absorber used packs bottom girder inner chamber into, does not change any structure, the profile appearance of automobile, and applicable new car, used car, cart, dolly all can be selected;
4, the energy-absorbing rate of the intensity of carbon fiber composite material bottom girder, case and carbon fiber reinforced metal aerated materials energy absorber is all better than ordinary steel product;
5, in the time occurring low speed collision or the impulsive force that knocks into the back in energy absorber elastic deformation area, compressed energy absorber can be recovered original state voluntarily, the use of still can remaining valid of safe beam.
For realizing technique scheme, technical matters to be solved is:
1, safe beam is formed by bottom girder, case and energy absorber combination adhesion, and wherein forward and backward bottom girder and case select carbon fiber composite material to make, and energy absorber selects carbon fiber reinforced metal aerated materials to make, and high strength polymer binder is selected in combination adhesion.
2, forward and backward bottom girder and case, makes by different automobile types bumper/spoiler physical dimension, employing integrated molding mode, and bottom girder thickness is 3-4 times of case thickness.
3, energy absorber energy-absorbing rate is (3～5) 104kJ/m
3, the cube shaped or cylindrical that adopts integrated molding mode to make to match with bottom girder or the energy absorber of cuboid.
4, the assembling mode of safe beam is: according to basic specifications such as vehicle, the speed of a motor vehicle, load-carryings, multiple energy absorbers below of calculative determination sticks in the bottom of bottom girder inner side with high strength polymer binder, then case is sticked in to energy absorber top, is assembled into one.
accompanying drawing explanation
Fig. 1 is the automotive safety girder construction schematic diagram of carbon fiber composite material and carbon fiber reinforced metal aerated materials.
The specific embodiment
Referring to Fig. 1,1 is carbon fiber composite material case, and 2 is carbon fiber composite material bottom girder, and 3 is carbon fiber reinforced metal aerated materials energy absorber; Referring to A-A section in Fig. 1, wherein main energy absorber 3 line of centerss face the line of centers installation of the forward and backward longeron of automobile, and auxiliary energy absorber distributes facing to the line of centers left and right of forward and backward safe beam; In the front bottom girder and rear bottom girder of forward and backward safe beam, by design-calculated requirement and position, adopt adhesive approaches, by energy absorber below and bottom girder bottom adhesion, energy absorber top and case adhesion, be configured to forward and backward safe beam, then link together with front end, the rear end of bolt and automobile longitudinal girder.
