It realizes being automatically repaired for collision bumper after impact loading, is keeping and conventional collision bumper property unanimous circumstances
Under, realize substantially drop weight.
Background technique
Collision bumper is generally disposed at the front and rear portion of vehicle, when head-on crash and rear-end collision occurs, needs
Have preferable energy absorption characteristics, convenient for the dissipation of collision energy, and mitigates and rushed suffered by the critical component and assembly being coupled
It hits.Conventional collision bumper is to be fabricated by steel plate through processes such as roll bending, punching press, welding, in order to guarantee its impact resistance
Property and reliability, usually exist and expect thick redundancy, there is the heavy spaces of biggish drop；And after collision accident generation, if collision
Biggish deformation occurs for buffer, needs to replace immediately, otherwise will affect its buffering energy-absorbing effect.
Summary of the invention
The present invention proposes a kind of bionical skeleton-type memorial alloy collision bumper, can be the effect for being parallel to the vehicle longitudinal axis
Power provides enough barrier forces.Due to using bionical skeleton-type design concept, the path for participating in crash energy absorption and dissipation is more,
The carrying participation of each skeletal layer is high, and integral energy-absorbing is good.Using NiTi marmem as bone material, carried in impact
After lotus unloading, original state can be returned back to, is obviously improved the service life of buffer, and total with the roll bending steel of traditional handicraft
At comparing, light weight effect is significant.
The present invention is directed to the functional characteristics of front part of vehicle and rear impact buffer, to promote collision bumper energy-absorbing effect
It is designed using bionical skeleton-type structure-design technique using NiTi shape memory alloy material and light composite material for target
Bumper for vehicles when being collision.Wherein, NiTi shape memory alloy material is made through cutting, punching press, heat treatment, shape training, welding
At the bionical bone in the inside of buffer；Coating of the carbon fibre composite plate as buffer, plays envelope and fixing internal
The effect of bone；Carbon fibre composite plate and NiTi marmem bone are fixed by resene glue sticking.Side carbon
Staying there are four bolt hole for fibre cover, achieves a fixed connection convenient for buffer and the other components of vehicle.Such crusherbull zone
Device structure has good energy absorption characteristics, and the recovery characteristic using NiTi shape memory alloy material after load unloading, comes
Realize the automatic rebounding reparation of whole bone after impact load unloads；The structure-design technique and lightweight composite wood of bionical skeleton-type
The application of material can guarantee that weight reduces by 30% or more compared with the buffer structure of same level vehicle.Similar bionical skeleton-type note
Recall the field of structural design that alloy collision bumper does not appear in vehicle collision protection.
The present invention includes carbon fibre composite coating and NiTi shape memory alloy bionic bone, NiTi shape note
The upper and lower surfaces for recalling alloy bionic bone cover carbon fibre composite coating, and carbon fibre composite coating passes through oxygen
Change resin glue to be adhesively fixed with the realization of bionical bone, constitutes collision bumper structure.The side carbon fiber of collision bumper is compound
Material coating is stayed there are four bolt hole, is achieved a fixed connection by other components of bolt and nut and vehicle.Described
NiTi shape memory alloy bionic bone is successively formed by welding by M font NiTi alloy bracket and groined type NiTi latten
, M font NiTi alloy bracket is welded on groined type NiTi latten, forms single layer skeleton structure, single layer skeleton structure
Successively welding forms NiTi shape memory alloy bionic bone.
Upper and lower surfaces covering of the carbon fibre composite coating as collision bumper；
NiTi shape memory alloy bionic bone is the M font through wire cutting, punching press, heat treatment, shape training manufacture
What NiTi alloy bracket and the groined type NiTi latten manufactured through wire cutting technology were successively formed by welding.
The side carbon fibre composite coating of collision bumper is stayed there are four bolt hole, passes through bolt and nut and vehicle
Other components achieve a fixed connection.
The present invention can be used for the collision protection and crash energy absorption equipment at design vehicle front, rear portion, and it is passive to be conducive to be promoted
Security performance and light weight effect.
Carbon fibre composite coating can be according to rigidity and intensity requirement, using different performance grade, different fiber rows
The carbon fiber board of column direction, different-thickness.
Through wire cutting, punching press, heat treatment, shape training manufacture M font NiTi alloy bracket, play support, energy-absorbing,
And the function of shape is automatically replied, it is each laminated to play connection for the groined type NiTi latten manufactured using wire cutting technology
The effect of golden bracket, M font NiTi alloy bracket and groined type NiTi latten weld to form single layer skeleton structure, by single layer
Skeleton structure is successively welded into NiTi shape memory alloy bionic bone.
Beneficial effects of the present invention:
The collision bumper that traditional heavy wall metal structure form can be substituted, in the premise for having same buffering energy-absorbing performance
Under, realize lightweight；Or in the case where equivalent weight is horizontal, buffering energy-absorbing effect is substantially improved, improves the whole crash-worthiness of vehicle
Energy.Original shape, the service life of Promoting Layered Buffer device are automatically replied after shock loading unloading using NiTi marmem.
The stability of buffer overall profile in load bearing process is kept using carbon fibre composite coating；Utilize NiTi shape memory
Alloy bionic bone Promoting Layered Buffer energy-absorbing is horizontal, and reduces shock loading damage caused by the other components of vehicle and occupant；And
NiTi marmem can automatically return to the shape of initial training after external force unloading, and then support to be pressurized and generate deformation
Position return back to original state.In addition, the design method of the application of lightweight carbon fibre composite and bionical skeleton-type
Overall weight is reduced significantly, is conducive to the light-weight design of vehicle.The material type of carbon fibre composite coating and
Angle, the arrangement of bracket are close at the top of M font NiTi alloy bracket in intensity rank and NiTi shape memory alloy bionic bone
Spend the front, rear impact guard that according to the completely new optimization design of different bearer function progress, can can be used for design vehicle
