Abstract
The utility model provides a vehicle bumper and a vehicle. The vehicle bumper comprises a support and a bar connected with the support, an outer cover plate is covered outside the bar, a gas chamber is arranged in the bar, and shear thickening fluid is filled in the gas chamber of the bar. In the scheme, the shear thickening fluid is filled in the bar of a hollow steel tube or coated on the inner wall of the steel tube to make a shear thickening buffer type bumper. When the vehicle is collided, the bumper can quickly absorb collision energy to achieve buffering effect. In addition, impact resistance of the bumper is improved, weight is reduced, and cost is lowered.
Description
Technical field
The utility model relates to automobile manufacturing field, refers to especially a kind of Federal bumper and vehicle.
Background technology
Along with the develop rapidly of automobile manufacture industry, people more and more pay attention to the safety of automobile.Federal bumper as safety device, is the important component part of vehicle structure, when collision happens, can effectively reduce personal casualty and automobile damage rate.The collision prevention girders of bumper/spoiler is generally high strength steel or aluminum alloy material at present, and the main intensity and the thickness that improve material of relying on improves energy-absorbing effect, this means that cost increases, and the thickness that improves material is unfavorable for also with the car weight that increases energy-conservation.
STF is to be dispersed in by micro-nano granules a kind of novel nano composite material that forms in certain basal liquid.It is very easy to distortion under low shear rate, can be as liquid slow flowing, be subject to the huge foreign impacts such as high-rate of shear and do the used time and can become hard solid in moment but work as it, after external force removes, again can be mobile as liquid.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of Federal bumper and vehicle, and is high with workout cost, the problem that bumper/spoiler is heavy.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of Federal bumper, comprise support, with the whippletree that described support is connected, described whippletree is coated with outer cover plate outward, be provided with air cavity in described whippletree, be provided with STF in described whippletree air cavity.
Wherein, be perfused with STF in described air cavity.
Wherein, be coated with STF on described air cavity inwall.
The utility model embodiment also provides a kind of vehicle, comprises car body, also comprises the Federal bumper for energy-absorbing buffering, and the support of described Federal bumper is fixed on described car body.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, by perfusion STF in the whippletree of hollow steel pipe or at steel pipe inner wall coating STF, make the shear thickening energy management bumper.Vehicle is when collision, and bumper/spoiler can absorb collision energy fast, plays buffering effect; Improve simultaneously the shock-resistant ability of bumper/spoiler, alleviated weight, reduced cost.
Description of drawings
Fig. 1 is the structural representation of a kind of Federal bumper of the utility model embodiment.
［ main element nomenclature ］
1: outer cover plate;
2: whippletree;
3: air cavity;
4: support;
5: STF.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model is high for existing bumper/spoiler cost, and the problem of Heavy Weight provides a kind of Federal bumper.
As shown in Figure 1, a kind of Federal bumper of the utility model embodiment, comprise outer cover plate 1, whippletree 2, support 4, described whippletree 2 is arranged on support 4, and be hollow steel pipe, the weight that has alleviated vehicle body has also reduced cost, the outer outer cover plate 1 that is coated with of described whippletree 2, and described support 4 is welded on car body, in order to fixing whole Federal bumper.
As shown in Figure 1, be provided with air cavity 5 in described whippletree 2.In the utility model embodiment, to the interior perfusion STF 3 of air cavity 5, or be coated with STF 3 on air cavity 5 inwalls, described STF 3 is a kind of novel nano composite materials, having can be slow mobile as liquid under low shear rate, makes in foreign impacts such as high-rate of shear the characteristic that the used time can become hard solid moment.Whippletree 2 is at perfusion or the rear formation Federal bumper of coating STF 3, collision speed of vehicle though is larger, and the rate of shear that is subject to of the STF 3 in whippletree 2 is also larger, and the viscosity of STF 3 is also larger, absorb fast collision energy, thereby play buffering effect; Simultaneously the intensity of whippletree 2 increases thereupon, thereby prevents that safety lever from producing serious deformation, effectively reduces damage that collision causes automobile and to occupant's injury.
The utility model embodiment also provides a kind of vehicle, comprising: car body, also comprise the Federal bumper for energy-absorbing buffering, and the support of described Federal bumper is fixed on described car body.
In such scheme, by perfusion STF in the whippletree of hollow steel pipe or at steel pipe inner wall coating STF, make the shear thickening energy management bumper.Vehicle is when collision, and bumper/spoiler can absorb collision energy fast, plays buffering effect; Improve simultaneously the shock-resistant ability of bumper/spoiler, alleviated weight, reduced cost.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
