Abstract

The invention relates to a support frame of an automobile forecabin and the automobile forecabin applying the same, aiming at enhancing the lateral rigidity of the automobile forecabin so as to improve the transversely swinging mode of the automobile forecabin and enhancing the NVH (Noise Vibration and Harshness) property of an automobile. The support frame of the automobile forecabin comprises a base, a left connecting rod and a right connecting rod, wherein the left connecting rod and the right connecting rod are respectively connected at both sides of the base; the end parts of the left connecting rod and the right connecting rod are provided with bolt holes; the base of the support frame of the automobile forecabin is fixed on a front baffle plate of the automobile forecabin; the left connecting rod is connected with a shock absorber bearing positioned at the left side of the automobile, and the right connecting rod is connected with a shock absorber bearing positioned at the right side of the automobile. The support frame of the automobile forecabin and the automobile forecabin applying the same have simple structure and lower cost, and is easy for manufacture and realization; in addition, the connecting rods combine the front baffle plate with a stiffening beam into a shape similar to a tripod so as to convert the bending rigidity of the stiffening beam into the compressive rigidity of the connecting rods, therefore the lateral rigidity of the forecabin is effectively enhanced, the mode of the forecabin is improved, and the NVH property of the integral automobile is enhanced.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an automobile front cabin bracket and an automobile front cabin using the bracket. Background technique [0002] Mode and stiffness are important factors affecting the NVH performance of the car body. A car body with good modal and stiffness performance can not only reduce vibration and noise, but also avoid fatigue problems caused by vibration. With the improvement of automobile performance requirements, the requirements for body modality and stiffness are also constantly increasing. The connection relationship and connection reliability between body sheet metal parts directly affect the modality and stiffness of the body. As an important part of the car body, the front compartment is used to house important assemblies such as the automobile engine, transmission, steering system, and battery. The quality of these assemblies has a great influence on ...
