Description
Technical field
The utility model relates to automobile technical fields, more particularly to a kind of basalt Anti-impact vehicle bumper.In addition,
The utility model further relates to a kind of automobile including above-mentioned basalt Anti-impact vehicle bumper.
Background technique
The development trend of World Auto Industry shows；Safety, the automobile of energy-saving and environmental protection are own through becoming 21 century development of automobile
Mainstream, automotive light weight technology is undoubtedly its optimal path, and one of mainstream material of automotive light weight technology is exactly automobile composite wood
Material.Advantage on automobile using composite material compared with steel is: loss of weight 20~40%；Flexibility in terms of punching press moulding,
And metal stamping is limited sending aspect；Reduce by 40~60% die cost；Assembly cost is reduced, when reduction fills cruel
Between；Corrosion-resistant, damage resistant, resistance to recess reduces noise vibration, higher damping；Material and process innovation can be in save the costs
Under the premise of increase added value；Due to that can absorb more energy, structure is safer.In miscellaneous automobile composite wood
In material, carbon fibre composite using oneself through more and more extensive.
When head-on crash occurs for automobile, bumper collides first, and can protect automobile to a certain extent
Car body and occupant.Bumper can be divided into insurance lever plate and installation shell.Installing shell is a non-structural part, it can rise
To the effect for reducing air drag.Energy absorbing device, energy absorption dress can be added between insurance lever plate and installation shell
Set the part kinetic energy for absorbing and generating in collision process.Insuring lever plate is a structural element, it is absorbed by bending
The energy generated in low speed collision.In general, mainly there are four effects for bumper assembly: in automobiles and other vehicles or object
When low speed collision occurs, it can protect fender, and radiator, hood and lamps and lanterns are without damage；High velocity impact is occurring
When, it can be by the other parts of the energy transmission of collision to automobile；When automobile and pedestrian collision, it can make pedestrian's
Injury reduces；Bumper must aerodynamically reach standard；There is bumper, decoration and beautification vehicle body can be played
Purposes.
Bumper includes insurance lever plate and installation shell, and the insurance lever plate and the side for installing shell are equipped with tightly
Fixing bolt and connecting plate, and the insurance lever plate is fixedly connected with installation shell by connecting plate, the fastening bolt is passed through respectively
It wears and sets in insurance lever plate and installation shell, this kind of Anti-impact vehicle bumper has high-density sponge spring layer and foam
Plastic layer, and high-density sponge spring layer is made of high-density sponge, when automobile is by hitting, high-density sponge spring layer
The power that outer bound pair automobile applies will be greatly reduced, so that the safety of driver in automobile be allowed to be improved, and encryption layer by
Carbon fibers/fiberglass hybrid composite is made, and improves the ductility of the first support tube and the second support tube, allows device
Impact resistance is reinforced.
Automobile front and back end is equipped with bumper, not only has decoration functions, more importantly absorbs and mitigates foreign impacts power, prevents
Protect the safety device of vehicle body protection vehicle body and occupant safety function.Many years before, automobile front/rear collision bumper is with metal material
Based on, with steel plate punched at U-lag steel, being surface-treated chromium plating has one section with vehicle body together with longitudinal beam rivet or weld
Biggish gap seems that an additional component up seems very unsightly.With the development of the automobile industry and engineering
For plastics in the extensive application of auto industry, bumper also moved towards the road of innovation as a kind of important safety device.
Automobile front/rear collision bumper will also pursue the harmony with car body moulding with uniformly, chase after other than keeping original defencive function at present
Ask the lightweight of itself.
But existing bumper, most of bumpers are all metal material and plastic product, metal material
Cost and maintenance cost are very high, the crashworthiness of plastic product be not comparatively it is classic, protective performance is not strong enough,
When automobile is by hitting, the shock force coefficient of weakening is not able to satisfy the demand of people, and hit when the side of automobile
When power is smaller, the side of bumper will be damaged, but people need to replace entire bumper, allow the economy of people
Loss improves, and has aggravated the financial burden of people, and the impact resistance of entire bumper is also not strong enough.
It is that current those skilled in the art are badly in need of solving in conclusion how to effectively improve the impact resistance of bumper
The problem of.

To weaken impact force significantly, the safety of device is improved, when automobile is by hitting, high-density sponge spring layer 2 will
Greatly reduce the power that outer bound pair automobile applies, so that the safety of driver in automobile be allowed to be improved.High-density sponge spring
Layer 2 and foam layer 3 are evenly distributed in putting groove, are easy to fixed high-density sponge spring layer 2 and foam layer
3。
For the basalt Anti-impact vehicle bumper in above-mentioned each embodiment, reinforce the middle position of protective baffle plate 8
It is provided with and reinforces protective baffle plate 7, be anticollision reinforced region, increase the crashworthiness of car door entirety, when vehicle doorn is hit,
Pressure, the safety of protection staff can be resisted well.Reinforce protective baffle plate 7 and reinforcement protective baffle plate 8 fits closely fixation, passes through
Reinforcing protective baffle plate 8 will directly can be accurately fitted within whole device on automobile, easy to connect, secured.
In order to further optimize the above technical scheme, the quantity of protective baffle plate can be two pieces, be distributed side by side, particular number
It can be determined according to different zones and applying in corresponding site with distribution situation, carry out local strengthening.It is logical to reinforce protective baffle plate 7
Overpopulation sponge spring and foamed plastics are made, light-weight, can weaken impact force significantly, and it is anti-to effectively improve basalt
The intensity of bumper is hit, and then effectively increases the integral strength of automobile door skin when side impact.
On the basis of above-mentioned each specific embodiment, structure glue 10 is the epoxy resin structural adhesive 10 of bi-component, infiltration
Property is good, and intensity is also preferable, and caking property is preferable.
The working principle of basalt Anti-impact vehicle bumper: firstly, installation shell 1 is passed through with protective baffle plate 8 is reinforced
Structure glue 10 connects, and fastening bolt 11 and attaching nut 9 are then installed through installation shell 1 and reinforce anti-guard block
Then left branch spring lever, right branch spring lever 4 and support connection bolt spring bar 6 setting are being reinforced protective baffle plate by the inside of plate 8
Then whole device is mounted on automobile by 8 side by pre-load nut 5, highly dense when installing shell 1 by hitting
Spending sponge spring layer 2, there are also foam layers 3 can weaken the power that outer bound pair reinforcement protective baffle plate 8 applies significantly, then reinforces anti-
Guard 7 can weaken again next impact force, then left branch spring lever, right branch spring lever 4 and support connection bolt
Subsequent impact force can be reduced a part to buffering by spring lever 6, then reinforce the left and right sides of protective baffle plate 8 by shock
When, impact force can be transferred to left branch spring lever, right branch spring lever 4 by they, and left branch spring lever, right branch spring lever 4 again pass power
It is defeated to be connected on bolt spring bar 6 to support, to weaken extraneous impact force significantly, protect the safety of people.
