Description

Bumper with shrink mark prevention mounting bracket

Technical Field

The utility model relates to the technical field of automobile parts, in particular to a bumper with a shrink mark prevention mounting bracket.

Background

The front end and the rear end of the automobile are provided with bumpers which not only have the decoration function, but also are more important to be safety devices which absorb and buffer the external impact force and protect the automobile body and passengers. Bumpers have the effect of providing safety protection, decorating vehicles, and improving the aerodynamics of vehicles. From the aspect of safety, the automobile can play a role in buffering when a low-speed collision accident occurs, and front and rear automobile bodies are protected; the pedestrian protection device can play a certain role in protecting pedestrians in case of accidents with the pedestrians. From the appearance, the decorative material has the decorative effect and becomes an important part for decorating the appearance of the car; meanwhile, the automobile bumper has certain aerodynamic effect.

Because the bumper is plastics injection moulding, so mainly fix the bumper body on the automobile body through the installing support, the design thickness of its body of traditional bumper is 3mm, the bottom of installing support is generally 1mm, installing support and bumper body integrated into one piece, because the bumper is the injection moulding product, consequently can form an obvious sink mark owing to the sudden change of thickness at the hookup location of installing support and bumper body, this sink mark is more obvious after bumper application (spraying paint), influence the whole appearance molding of car, and also lead to the design structure of mould relatively complicated owing to the structure of installing support and bumper body formula as an organic whole, the die sinking cost of mould has been increased.

Therefore, in order to solve the above problems, a bumper with a shrink mark-proof mounting bracket is needed, which can overcome the shrink mark defect of the original bumper appearance, simplify the die design of the mounting bracket and the bumper, make the automobile exquisite appearance, and meet the market demand.

SUMMERY OF THE UTILITY MODEL

In view of the above, an object of the present invention is to overcome the defects in the prior art, and to provide a bumper with a shrink mark prevention mounting bracket, which can overcome the shrink mark defect in the appearance of the original bumper, simplify the die design of the mounting bracket and the bumper, create a delicate appearance for the automobile, and meet the market demand.

The bumper with the shrink mark preventing mounting bracket comprises a bumper body and the mounting bracket, wherein the bumper body and the mounting bracket are fixedly connected after being subjected to split injection molding, and the split bumper body and the mounting bracket simplify the mold design, reduce the mold opening cost of the mold and also facilitate the guarantee of the injection molding quality of a single part.

Further, the installing support is including connecting face and bayonet socket, connect the face with bumper body inboard laminating and hot melt completely is connected, the bayonet socket is used for being connected with the automobile body lock, connects the face and contacts and form the face with the bumper face and be connected, and holistic connection is more firm, and the wholeness is stronger.

Furthermore, the connection surface and the bumper body are connected in a puncture welding mode, the puncture welding is mainly used for connection between plastic parts, the connection quality is uniform, and the connection strength is high.

Furthermore, the inboard hookup location of connecting the face of bumper body sets up the spacing groove that the shape suited with connecting the face, and the spacing groove not only can play the effect of location to the installing support, more can absorb the deformation that produces when connecting between face and the bumper, guarantees the dimensional tolerance and the assembly size chain of bumper.

Furthermore, the thickness of connecting the face is 1.5mm, and the thickness of bumper body is 3mm, does not produce great deformation after with connecting the face puncture welding, guarantees dimensional tolerance better.

Furthermore, the thickness of bayonet socket is 2.5mm, and the connection intensity can be guaranteed better to thicker bayonet socket, avoids bayonet socket to connect insecurely.

The utility model has the beneficial effects that: according to the bumper with the shrink mark preventing mounting bracket, the bumper body and the mounting bracket are formed in a split mode and then fixedly connected, an original integral die is simplified into two independent dies, the defect of shrink marks on the appearance of the integrally formed bumper is overcome, the exquisite appearance of an automobile is created, and the bumper meets the market requirements.
