Car body moulding harmony with uniformly, the lightweight of pursuit itself.Currently, the front/rear collision bumper of car is all made of plastics, claim
For plastic bumper.The plastic bumper of general automobile is made of outside plate, padded coaming and crossbeam three parts.Wherein outside plate and
Padded coaming is made of plastic, and crossbeam is stamped to form U-lag with flat cold-rolled sheet；Outside plate and padded coaming are attached to crossbeam.
With the rapid development of auto industry, automotive light weight technology designs the common recognition for having become industry.It is thin for vehicle loss of weight
Body, not only can be with fuel-saving environmental protection, but also can improve dynamics of vehicle performance.The front/rear collision bumper being made of plastics is as the front and back of automobile
It surrounds, general own total weight also has certain lightweight space in 8~10kg or so.
Utility model content
In view of the foregoing deficiencies of prior art, the purpose of this utility model is to provide a kind of lightweight bumper and
Vehicle realizes lightweight target under the premise of ensureing bumper performance by reducing the material thickness of bumper.
In order to achieve the above objects and other related objects, the utility model provides a kind of lightweight bumper, including insurance
Thick stick main body, installation point position, horizontal surface areas and pressing area；The thickness of the bumper body is 2.2~2.3mm；It is described
The thickness of installation point position, the horizontal surface areas and the pressing area is linearly increasing to 2.8mm from 2.2~2.3mm and protects
It holds constant.
In one embodiment of the utility model, the bumper is made of PP resin material.
In one embodiment of the utility model, the installation point position, the horizontal surface areas and the pressing area
Thickness is from 2.2~2.3mm according to 100:1 speedup increases to 2.8mm.
In one embodiment of the utility model, the installation point position, the horizontal surface areas and the pressing area are equal
Including transitional region and stability region, the thickness of the transitional region is linearly increasing to 2.8mm from 2.2~2.3mm；The stabilization
The thickness in region is 2.8m.
In one embodiment of the utility model, the thickness of the bumper body is 2.3mm, the installation point position, institute
The thickness for stating horizontal surface areas and the pressing area is linearly increasing to 2.8mm from 2.3mm and remains unchanged.
Meanwhile the utility model provides a kind of vehicle, including above-mentioned lightweight bumper.
As described above, the lightweight bumper and vehicle of the utility model, have the advantages that：
(1) under the premise of ensureing bumper performance, lightweight target is realized by reducing the material thickness of bumper；
(2) it is effectively improved the economic benefit of vehicle.

Specific implementation mode
Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below
Content disclosed by specification understands other advantages and effect of the utility model easily.
It should be clear that structure, ratio, size etc. depicted in this specification institute accompanying drawings, only coordinating specification to be taken off
The content shown is not limited to the enforceable restriction item of the utility model so that those skilled in the art understands and reads
Part, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing
Under the effect of the utility model can be generated and the purpose that can reach, should all still it fall in the revealed technology of the utility model
In the range of Rong get Neng is covered.Meanwhile it is cited such as "upper", "lower", "left", "right", " centre " and " one " in this specification
Deng term, be merely convenient to being illustrated for narration, rather than to limit the enforceable range of the utility model, relativeness
It is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable scope of the utility model.
The lightweight bumper and vehicle of the utility model are insured under the premise of ensureing bumper performance by reducing
The material thickness of thick stick realizes lightweight target, to increasing the economic benefit of vehicle.
As shown in Figure 1-Figure 3, in an embodiment, the lightweight bumper of the utility model includes bumper body 1, peace
Decorate position 2, horizontal surface areas 3 and pressing area.Wherein, installation point position 2 refers to installation when bumper is mounted on car body
Position, the usually periphery of on the upside of the bumper and left and right sides；Horizontal surface areas 3 refers to the periphery on the downside of bumper；Pressing area
Domain refers to the most weak band of position of bumper rigidity, depending on the concrete structure of bumper.Bumper body 1 is then to remove
Insurance bumper region except installation point position 2, horizontal surface areas 3 and pressing area.
The thickness of the bumper body 1 is 2.2~2.3mm；The installation point position 2, the horizontal surface areas 3 and institute
The thickness for stating pressing area is linearly increasing to 2.8mm from 2.2~2.3mm and remains unchanged.
