Problems solved by technology

[0003] 1. The use of iron products will lead to the overall weight of the rearview mirror, which may exceed the weight range of the door
[0004] 2. The surface of iron products is sprayed with plastic or painted. After bumping, the paint will be peeled off, which will cause the place to rust
[0005] 3. Since the inner wall of the steel pipe cannot be completely anti-rust, the inner wall will rust after a period of use, which will cause abnormal sound caused by yellow water flowing from the lower end of the steel pipe or rust residue generated

Abstract

The invention provides an aluminum supporting arm for an automobile rearview mirror and a manufacturing method for the aluminum supporting arm for the automobile rearview mirror. The aluminum supporting arm for the automobile rearview mirror is composed of an aluminum pipe, an aluminum sleeve, an upper protection cover and a lower protection cover, wherein the aluminum pipe and the aluminum sleeve are both made of aluminum alloy, the aluminum pipe is in a C shape, the aluminum sleeve is fixedly connected with the top end of the aluminum pipe, the aluminum sleeve is in a cylinder shape which is opened on two sides, an arc-shaped notch is formed in the top end of the aluminum pipe, the appearance of the notch is matched with the outer wall of the aluminum sleeve, the aluminum sleeve is fixed on the notch through welding, more than two connecting holes are formed in the bottom of the aluminum pipe, the connecting holes are through holes and distributed in an up-down mode, the upper protection cover wraps and covers the upper portion of the aluminum pipe and the aluminum sleeve, and the lower protection cover wraps and covers the lower portion of the aluminum pipe. The invention further provides the manufacturing method for the aluminum supporting arm for the automobile rearview mirror. The manufacturing method for the aluminum supporting arm for the automobile rearview mirror is simple in process and capable of achieving industrialized production.

Description

technical field [0001] The invention relates to a support arm for an automobile rearview mirror, in particular to an anti-rust aluminum support arm, and also provides a preparation method for the support arm, which belongs to the field of manufacturing and processing of auto parts. Background technique [0002] At present, the support arms for automobile rearview mirrors used in the market are all made of steel and made of steel pipes. There are the following problems in the long-term use process: [0003] 1. The use of iron products will lead to the overall weight of the rearview mirror, which may exceed the weight range of the door. [0004] 2. The surface of iron products is sprayed with plastic or painted. After being bumped, the paint will be peeled off, which will cause the place to rust. [0005] 3. Since the inner wall of the steel pipe cannot be completely anti-rust, the inner wall will rust after a period of use, which will cause abnormal sound caused by yellow wa...
