Light-weight overall mud guard assembly

Abstract

The invention discloses a light-weight overall mud guard assembly which comprises a front mud guard, a rear mud guard, a top cover and a locking mechanism assembly, wherein bulges are arranged in the middles of the front mud guard and the rear mud guard; bolt adjusting holes are formed in upper platforms of the bulges; transverse through holes are formed in outer sides of the bulges; pressing plates are arranged on the front mud guard and the rear mud guard; the top cover is fixed together with the front mud guard and the rear mud guard through pull belts and the pressing plates; the locking mechanism assembly comprises a bottom plate, a fixed side, a movable side and fixing hinge pins; the bottom plate, the front mud guard and the rear mud guard are integrally formed in an injection molding manner; the fixed side is welded with the bottom plate; the movable side is connected with the fixed side; fastening bolts penetrate through the bolt adjusting holes, the bottom plate and long holes in the fixed side and are connected with screw nuts; a double-arched toothed round hole is formed in the middle of the fixed side; a mud guard bracket penetrates through the transverse through holes and is arranged inside the double-arched toothed round hole. Problems that a mud guard is cracked, rotated, disassembled and loosened to cause pivoting can be overcome, an assembling process is simplified, and the light-weight overall mud guard assembly has the advantages of simple structure, light weight and high reliability.

Description

technical field [0001] The invention relates to a lightweight integral fender structure, which belongs to the technical field of auto parts structures. Background technique [0002] For commercial vehicles, especially heavy-duty tractor vehicles, the vibration intensity and acceleration at the rear of the vehicle are particularly large, causing the fenders at the rear to be subjected to impact forces from up and down, front and rear directions all the time. First of all, in the prior art, the locking mechanism of the fender and the fender are basically assembled together separately. Due to the limitation of this structure, there are generally problems that the locking mechanism and the fender are connected and fixed. In the case of strong vibration or more ice on the fender in winter and snow, problems such as fender falling off and cracking are very likely to occur; the existing fender locking mechanism and fender support round tube are basically hoop locks Tight, using su...
