Front-end module carrying frame of car

Abstract

The invention discloses a front-end module carrying frame of a car, which comprises a sheet-metal part and a plastic part. The front-end module carrying frame of the car is characterized in that the sheet-metal part and the plastic part are combined to form a whole by the injection molding. The plastic part attached on the sheet-metal part by the injection molding plays a good role in reinforcing a sheet-metal stamped component and simultaneously forms mounting spaces of a left headlight and a right headlight and a heat radiator mounting space together with sheet-metal components. The invention has the beneficial effects that the metal-sheet part and the plastic part are combined to form the front-end module carrying frame by adopting the injection molding; the integral strength of the front-end module carrying frame is improved; simultaneously, the requirement on light weight is met; the plastic part is respectively provided with reinforcing ribs at positions corresponding to an upper beam and a lower beam of the sheet-metal part to improve the integral strength; the metal-sheet part adopts the impact molding; and all mounting positioning holes are arranged on the sheet-metal part so as to ensure mounting precision.

Description

technical field [0001] The invention belongs to automobile body components, in particular to an automobile front-end module carrier. Background technique [0002] The front-end module of the vehicle is a unit that integrates the cooling module-radiator, hood hook, hood lock, headlights, etc., and the front-end module carrier is a frame structure for assembling the front-end parts, and the assembled whole forms the front-end module. As the development trend of car body, modular design is getting more and more attention. The front end of the body is the earliest module design in the body structure. The integrated front-end module is an important part of the body. Its assembly process and its own structural strength requirements become the body The focus of the structural designer's consideration. The traditional front-end module carrier is mainly made of plastic parts, and the parts with high strength requirements (such as: the upper part of the module - the upper beam, the ...

Problems solved by technology

But this also creates a problem: since the main part is plastic parts, the front-end module as a whole, its overall strength is difficult to meet the requirements, and local reinforcement cannot effectively meet the design requirements. In addition, due to the cooling shrinkage of the plastic material molding, it is inevitable Some parts have an impact on the installation manufacturability
