Front subframe assembly, car and method for mounting front subframe assembly and front bumper

Abstract

The invention discloses a front subframe assembly, a car and a method for mounting the front subframe assembly and a front bumper. The front subframe assembly comprises a front subframe main body and a front extension beam, wherein the front ends of two sides of the front subframe main body are provided with forward first connection plates; the first connection plates are provided with hooking holes; two ends of the front extension beam are provided with second connection plates toward the front end of the front subframe main body; the second connection plates are provided with hooks which are matched with the hooking holes; the first and second connection plates are overlapped; the hooks are hooked in the hooking holes. By utilizing the split type design of the front subframe main body and the front extension beam, the mounting process of the front subframe assembly can be divided into a front subframe main body mounting process and a front extension beam mounting process; during the mounting, enough front extension beam assembling space can be retained between the front bumper and the front subframe main body, so that the mounting difficulty of the front subframe assembly is reduced and the mounting efficiency is enhanced.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to a front auxiliary frame assembly of an automobile, a method for installing the front auxiliary frame assembly and a front bumper, and an automobile. Background technique [0002] figure 1 It is a structural schematic diagram of the front sub-frame assembly of an existing automobile, figure 2 for its top view, image 3 its side view. Such as figure 1 , figure 2 , image 3 As shown, the front subframe assembly 1 of an existing automobile is mainly composed of a front subframe main body 11 and a front extension beam 12 . Wherein, the front extension beam 12 is provided for cooperating with the collision safety, and the connection with the front sub-frame main body 11 can be connected by welding or bolts. Specifically, the left and right ends of the front extension beam 12 are provided with connecting arms 121, and the left and right ends of the front subframe body 11 are ...

AI Technical Summary

Problems solved by technology

As mentioned above, since the front extension beam 12 is accommodated in the enclosed space formed by the front bumper, the front bumper and the front extension beam 12 in the front sub-frame assembly 1 have a relatively large overlapping portion in the Z direction. Part of the assembly space is occupied, so that after the front bumper is assembled, the front extension beam 12 in the front sub-frame assembly 1 is difficult to snap into the surrounding space of the front bumper, thereby increasing the space of the front sub-frame assembly 1. Difficult to install, even after installing the front bumper, it may not be possible to complete the installation of the front subframe assembly 1
