Vehicle front body structure

Abstract

The invention provides a vehicle front body structure which has the advantages of good process feasibility and easy manufacture. The vehicle front body structure is characterized by comprising a front baffle plate and a front windshield lower bean assembly, wherein the front windshield lower beam assembly comprises a front windshield lower beam, a lower supporting plate of the front windshield lower beam and a running water tank body; the upper end of the front baffle plate is fixedly connected with the front windshield lower beam and the lower supporting plate of the front windshield lower beam through the running water tank body; and sealing cavity structures extending along the width direction of the vehicle body are formed among the running water tank, the front windshield lower beam and the lower supporting plate of the front windshield lower beam. In the invention, the front torsional rigidity of the vehicle body can be effectively improved through a plurality of sealing cavity body structures, and through the connection of a left damper seat and a right damper seat, the local rigidity of the damper seats is also obviously improved; and in addition, the front baffle plate with a novel structure is adopted to effectively separate noise transmitted from a front cabin, thereby the NVH (Noise Vibration and Harshness) performance of a passenger compartment is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an automobile front body structure, that is, an automobile front fender and a partial structure of the automobile body around it. Background technique [0002] The front baffle of a car is the partition between the engine compartment and the passenger compartment. It has functions such as sound insulation and heat insulation. In the event of a collision accident, the front baffle must have a certain rigidity and strength to protect the safety of the occupants in the passenger compartment. The body of the front fender will have a certain influence on the torsional rigidity of the front part of the vehicle body, and at the same time, the overlapping relationship between the front fender and the front shock absorber seat will also affect the local stiffness and strength of the front shock absorber seat to a certain extent, so The design of the front fend...

AI Technical Summary

Problems solved by technology

The traditional car front fenders are only made of ordinary steel plates, which have poor sound insulation and heat insulation effects; at the same time, the front body structure of the car does not fully consider the impact of the front fender structure on the performance of the car body, the design is relatively simple, and the front fender cannot be used. Plate to improve the front torsional stiffness of the front body of the car and the local stiffness of the front shock absorber seat
