Description

Front Structure for Vehicle The present invention relates to a vehicle front structure, and more specifically, to a vehicle front structure capable of distributing load during a vehicle collision. The vehicle includes a front compartment and a passenger compartment partitioned by a dashboard. The powertrain, including the prime mover, is located within the front compartment. For example, in an internal combustion engine vehicle, the powertrain, including the internal combustion engine, is located in the front compartment, while in an electric vehicle, the powertrain, including the electric motor, is located in the front compartment. The front compartment is defined by the vehicle front structure, which includes a front end module, a pair of front side members connected to the front end module, a pair of fender apron members connected to the front end module, a pair of damper housings connected to the pair of front side members, and a dash panel. A pair of front side members are spaced apart along the width direction of the vehicle, and each fender apron member is bent in the up-down and left-right directions, with the front end of each fender apron member connected to the front bumper. It is configured to support the fenders located on both the left and right sides of the vehicle. Each damper housing is configured to support a damper, such as a shock absorber of the vehicle's suspension system, and each damper housing can be positioned between each front side member and fender apron member. A cowl is attached to the top of the dashboard panel. In conventional vehicle front structures, the upper crossmember of the front-end module is composed of injection-molded plastic or injection-molded plastic with steel inserted, resulting in relatively weak rigidity; consequently, the structure is vulnerable to load transmission. In addition, in the existing vehicle front structure, the fender apron member has a 3D bending shape that bends in all directions (up, down, left, and right), making it difficult to support the load and allowing it to easily bend. Consequently, when a vehicle collision occurs, such as a frontal collision, small overlap collision, or offset collision, the fender apron member cannot stably support the load. As such, existing vehicle front structures had the disadvantage of not being able to distribute the load evenly during a vehicle collision.
