Load-supporting mirror shell structure of automobile mirror

Abstract

The invention discloses a load-supporting mirror shell structure of an automobile mirror. A mirror shell, an upper mirror arm and a lower mirror arm are fixed by an upper mirror arm connection structure and a lower mirror arm connection structure, the upper mirror arm connection structure and the lower mirror arm connection structure include inserting holes formed in the upper end and the lower end of the mirror shell correspondingly, the ends, connected with the mirror shell, of the upper mirror arm and the lower mirror arm are tubular joints matched with the corresponding inserting holes, each tubular joint is fastened with a matched inserting hole through a set screw, a mirror shell bearing structure is arranged between the upper mirror arm connection structure and the lower mirror armconnection structure, the mirror shell bearing structure includes a main reinforcing rib extending in the length direction of the mirror shell, and the main reinforcing rib is arranged between the upper mirror arm connecting structure and the lower mirror arm connecting structure and is connected with the upper mirror arm connecting structure and the lower mirror arm connecting structure. According to the load-supporting mirror shell structure of the automobile mirror, the production steps are optimized, the working efficiency is improved, the strength and stiffness properties of products canbe improved by decreasing the number of connecting parts, and meanwhile, the shaking risk and the stability of rearview mirror use are also lowered.

Description

technical field [0001] The invention relates to the technical field of manufacturing rearview mirrors for buses and heavy-duty vehicles, in particular to an automobile mirror bearing type mirror housing structure. Background technique [0002] Cars are increasingly becoming a part of human life, and higher and higher requirements are placed on their economy and environmental protection. Therefore, for the rearview mirrors of large vehicles such as buses and heavy-duty vehicles, as important automotive exterior parts, there are higher requirements in many aspects such as service life and production efficiency. [0003] The traditional rearview mirror bracket structure is composed of a mirror rod made of metal or metal composite material and the upper and lower plastic mirror arms, so the number of parts is large, and the material properties of various parts are completely different, resulting in The disadvantages of high cost and difficult assembly make the price of high-qua...

Problems solved by technology

[0003] The traditional rearview mirror bracket structure is composed of a mirror rod made of metal or metal composite material and the upper and lower plastic mirror arms, so the number of parts is large, and the material properties of various parts are completely different, resulting in Disadvantages such as high cost and difficult assembly make the price of high-quality rearview mirrors high

[0004] Moreover, due to the large number of parts, the assembly requirements are high and difficult, the joints are easily damaged after assembly, the production efficiency and cost are not good, and the joints of the mirror arm and the mirror rod are easily broken due to the rigid connection between the metal material and the polymer material. , reducing service life
