Aluminum oxide film layer license plate frame

Abstract

The invention discloses an aluminum oxide film layer license plate frame. The aluminum oxide film layer license plate frame comprises a license plate frame body, wherein the license plate frame body comprises a convex edge and a groove integrally formed with the convex edge, the bottom of the groove is provided with four installation holes conforming to relevant national standards, the surface of the license plate frame body is provided with an aluminum oxide film layer, a special aluminum tape for a motor vehicle license plate is arranged inside the license plate frame body, the thickness of the aluminum oxide film layer is 3 to 5 micrometers, and the thickness of the license plate frame body is 0.6 to 1 mm. The aluminum oxide film layer license plate frame has the advantages of high strength, good corrosion resistance, uneasiness in abrasion, high temperature resistance and non-conductivity and is suitable for various license plates in the market to use in various environments.

Description

technical field [0001] The invention belongs to the field of motor vehicle auxiliary accessories, and in particular relates to an aluminum oxide film layer license plate frame. Background technique [0002] The so-called license plate frame is the shelf for installing the license plate of the motor vehicle. It can also be called the license plate frame, the license plate holder, and the license plate frame. The role of license plate damage, at the same time, some imported car license plate mounting holes are different from domestic license plate mounting holes, and the license plate frame can also play a role in compatible with the installation of imported car license plates. [0003] At present, the market has plastic license plate frame, stainless steel license plate frame, aluminum alloy license plate frame, iron license plate frame, zinc alloy license plate frame, titanium alloy license plate frame, magnesium aluminum alloy license plate frame, etc.; different materials ...

AI Technical Summary

Problems solved by technology

[0003] At present, the market has plastic license plate frame, stainless steel license plate frame, aluminum alloy license plate frame, iron license plate frame, zinc alloy license plate frame, titanium alloy license plate frame, magnesium aluminum alloy license plate frame, etc.; different materials have different characteristics, ABS plastic, aluminum alloy 1. The iron license plate frame is the most common, and the price is relatively cheap, while the stainless steel, zinc alloy, titanium alloy, magnesium alloy license plate frame is of better quality, it is not easy to deform or rust when used, and of course the price is more expensive

[0004] With the development of science and technology and productivity, through reasonable process routes and processes, the aluminum alloy produced has made great breakthroughs in strength, and at the same time has the advantages of high elongation, good ductility and good corrosion resistance. , coupled with its original characteristics of light weight, strong plasticity, and recyclability, formed a popular and general-purpose aluminum strip / plate for motor vehicle license plates in the market; however, people found during use that the aluminum alloy surface The natural oxide film still has the problem of unsatisfactory effect in terms of corrosion resistance and wear resistance.
