Vehicle front body structure

A front body and automobile technology, which is applied to the superstructure, superstructure sub-assemblies, vehicle components, etc., can solve the problem that the torsional stiffness of the front body of the front baffle cannot be utilized, and the local stiffness and strength of the front shock absorber seat cannot be used. Comprehensive consideration of the front baffle, sound insulation, poor heat insulation effect, etc., to achieve the effect of improving NVH performance, improving local stiffness and strength, and improving front torsional stiffness

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

Abstract

The invention provides a vehicle front body structure which has the advantages of good process feasibility and easy manufacture, especially including a front baffle plate, a front windshield lower beam assembly, and a front baffle plate lower beam assembly formed by a lower reinforcing beam and a connection plate, wherein a lower end of the front baffle plate and the lower reinforcing beam are welded fixedly to form a sealing cavity structure extending along a vehicle body width direction, the lower reinforcing beam is fixedly connected to a front vertical beam of the vehicle through the connection plate, 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 the sealing cavity structure extending along the width direction of the vehicle body is formed among the running water tank, the front windshield lower beam and the lower supporting plate of the front windshield lower beam. The vehicle front body structure of the invention can effectively improve the front torsional rigidity of the vehicle body, also obviously increase the local rigidity of the damper seats, at the same time improve the NVH (Noise Vibration and Harshness) performance of a passenger compartment.

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...
