Abstract
The invention relates to the technical field of automobile parts, in particular to an automobile bumper. The automobile bumper comprises a bumper body, wherein the bumper body comprises an inner plate which is arranged on a body and an outer protective plate which is fixedly arranged on the inner plate; the surface of the inner plate is provided with a first pit which sinks towards the body of the inner plate; the surface of the outer protective plate is provided with a second pit which sinks towards the body of the outer protective plate; after the inner plate and the outer protective plate are assembled together, the first pit and the second pit form a buffer chamber. The first pit and the second pit form one buffer chamber; when collision force acting on the bumper is small, the collision force is firstly buffered by the outer protective plate and then born by the outer protective plate and the buffer chamber, so that the inner plate is not impacted to guarantee the safety of the inner plate, and only the outer protective plate is required to be replaced but the inner plate is not required to be replaced during maintenance to reduce the maintenance cost.
Description
Technical field
The present invention relates to technical field of automobile, be specifically related to a kind of Federal bumper.
Background technology
Federal bumper absorbs to relax foreign impacts power, the safety device of protection vehicle body; Existing bumper/spoiler is for adopting Shooting Technique, and an an injection moulding integrally-built bumper/spoiler sheet material out, by techniques such as surface sprayings, obtains a bumper product; The bumper/spoiler of this spline structure does not have buffer structure, when colliding, easily damages, and need to change whole bumper/spoiler, service expenditure is higher.
Summary of the invention
For above-mentioned technical matters, the invention provides a kind of Federal bumper, it when colliding, can cushion impact force, plays the certain protection to car body; And when slight impact, without the need to changing whole bumper/spoiler, relatively reduce service expenditure.
Realize technical scheme of the present invention as follows:
A kind of Federal bumper, comprise bumper body, bumper body comprises the inner panel be installed on car body, and the outer casing be fixedly installed on inner panel, inner plate surfaces is provided with the first pit to inner plate body depression, outer casing surface is provided with the second pit to outer casing body depression, and after described inner panel, outer casing are assembled together, above-mentioned first pit, the second pit form a cushion chamber.
Further, in order to the fire resistance making bumper/spoiler specifically certain, described outer casing, inner plate surfaces are provided with fireprotection layer.
Further, described fireprotection layer is the refractory fiber cotton layer of 2mm-5mm.
Have employed this programme, inner panel is fixedly installed on car body, and outer casing facing to body outer, then is fixedly installed on inner panel by the first pit, forms a complete bumper/spoiler; Wherein, the second pit is facing to the first pit, and such first pit, the second pit form a cushion chamber, to collide power hour at bumper/spoiler, first cushioned by outer casing, then cushion through cushion chamber, impact force is shared by outer casing and cushion chamber, and inner panel can not be impacted, ensureing the safety of inner panel, when keeping in repair, also only needing to change outer casing, and do not need to change inner panel, reduce service expenditure.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present invention;
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described;
See Fig. 1, a kind of Federal bumper, comprise bumper body 6, comprise the inner panel 1 be installed on car body, and be fixedly installed on the outer casing 2 on inner panel, inner panel and outer casing adopt the mode of bolt or screw or buckle to link together, inner plate surfaces is provided with the first pit 3 to inner plate body depression, outer casing surface is provided with the second pit 4 to outer casing body depression, and after inner panel, outer casing are assembled together, above-mentioned first pit, the second pit form a cushion chamber.Outer casing, inner plate surfaces are provided with fireprotection layer 5, and fireprotection layer can prevent extraneous burning things which may cause a fire disaster from lighting bumper/spoiler.Fireprotection layer is the refractory fiber cotton layer of 2mm-5mm, and concrete enforcement can be 2mm, 3mm, 4mm, 5mm.
