Abstract
The invention discloses an automobile bumper and belongs to the field of automobile accessories. The automobile bumper is used for solving the problem that buffering of a bumper shell is difficult to increase, and consequently the impact stress is difficult to resist. The automobile bumper comprises a bumper shell. The shell is an integrated injection molding piece, grids are arranged on the side, facing an installation support, of the shell, the grids are triangular and are distributed at the two ends and the middle end of the bumper, and lamp holes matched with automobile lamps are formed in the two ends of the shell. The automobile bumper has the beneficial effects that resistance stress is effectively improved at the reasonable stress positions, buffering is increased, the impact stress is resisted, and material waste is reduced.
Description
Technical field
The invention belongs to auto parts machinery field, specifically, be a kind of better bumper receiving the extraneous stamping press of mitigation.
Background technology
Bumper relaxes the safety device of foreign impacts power as absorbing, and protection vehicle body front and rear part and protection driver and crew are played an important role.
Wherein, whole bumper is played decisive role by the intensity of thick stick body, and the thick stick body of high intensity is more beneficial for being uniformly distributed of collision energy, but in the design, it is impossible to the purpose of intensity is reached to increase by unrestrictedly increasing thickness of steel product.
Vehicle front/rear collision bumper, except keeping original defencive function, is also pursued harmonious with car body moulding and unified, the lightweight of pursuit itself.The front/rear collision bumper of current car have employed plastics, and people are called plastic bumper.Plastic bumper is made up of three parts such as outside plate, padded coaming and crossbeams.Wherein outside plate and padded coaming are made of plastic, and crossbeam flat cold-rolled sheet is stamped to form U-type groove；Outside plate and padded coaming are attached on crossbeam, crossbeam and longitudinal beam screw joints, it is possible to disassemble at any time.The plastics that this plastic bumper uses; generally using polyester system and polypropylene-based bi-material, adopt injection moulding to make, plastic bumper has intensity, rigidity and dicoration; from safety; cushioning effect can be played when vehicle crashes, car body before and after protecting, from the appearance; naturally enough can be combined in one piece with car body; completely integral, there is good dicoration, become the vitals of decoration vehicle external form.
Existing bumper skin is difficult to self and increases buffering, resists impact stress, and the padded coaming being only made by being attached on crossbeam is to realize buffering effect.
Summary of the invention
Increasing buffering for there is bumper skin self in prior art, the problem of opposing impact stress is not enough, the invention provides one and can increase buffering, the bumper of opposing impact stress.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is as follows:
A kind of bumper, including bumper skin, the integrated moulding of shell, it has grid towards mounting bracket side, and grid is triangle, and its distribution is arranged on bumper two ends and middle-end, and there is the lamp hole coordinating car light at shell two ends.
Adopting the invention of technique scheme, the integrated injection mo(u)lding of shell ensure that its securement strength, for increasing the securement strength of shell, is set to the better triangular grid structures of steadiness inside the shell；The impact position of bumper is mainly based on two ends and middle impulsive force, therefore particularly important at bumper two ends and middle reinforcing, the waste of material and technique can be avoided loaded down with trivial details simultaneously, the lamp hole coordinating lamp installation is provided simultaneously, strengthen the use of bumper and attractive in appearance.
Limiting further, described grid side is fixing inside the shell, and it is 1cm-3cm from the distance inside shell., the restriction of this structure enhances the steadiness of bumper skin, it is to avoid taking of inner space.
Limiting further, described lamp hole is oval, the aesthetic limiting enhancing bumper skin of this structure.
The present invention is beneficial in that, is rationally effectively improved opposing stress at forced position, increases buffering, resists impact stress, reduces waste of material.

Detailed description of the invention
In order to make those skilled in the art can be more fully understood that the present invention, below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated.
As Figure 1-4, a kind of bumper, including bumper skin 2, the integrated moulding of shell 2, it has grid 1 towards mounting bracket side, and grid 1 is triangle, and its distribution is arranged on bumper two ends and middle-end, and there is the lamp hole 3 coordinating car light at shell 2 two ends.Grid 1 side is fixed on inside shell 2, and it is 2cm from the distance inside shell 2；Lamp hole 3 is oval.
During use, bumper is arranged on crossbeam, padded coaming is filled inside bumper skin 2, owing to automobile is in collision process, its two ends and middle-end are impulsive force primary contact point, therefore particularly important at bumper two ends and middle reinforcing, inside shell 2, it is set to steadiness good triangular mesh 1 structure；The lamp hole 3 coordinating lamp installation is provided simultaneously, strengthens the use of bumper and attractive in appearance.
Above bumper provided by the invention is described in detail.The explanation of specific embodiment is only intended to help to understand method and the core concept thereof of the present invention.It should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to the present invention carries out some improvement and modification, these improve and modify in the protection domain also falling into the claims in the present invention.
