Problems solved by technology

[0003] With the gradual popularization of automobiles and the deepening of people's understanding of automobiles, the method of improving the grade of automobiles is more and more recognized by automobile manufacturers and consumers. The car decoration strip made of aluminum and its alloy materials is installed on the car. Because the rear end of the door and window has corners, the existing car decoration strips are installed separately in two sections. The disadvantage of this is: in the two sections There is a gap at the junction of the car trim, which not only affects the aesthetics of the car trim, but also rainwater easily enters the inner side of the car trim from the gap, resulting in corrosion and rust in the gap
[0004] In addition, when the surface gloss of the existing car trim is treated, it is simply polished. In this way, the car trim is not only dull in appearance, but also has poor elastic strength and tensile strength, and it will become rough as the rain corrodes , prone to cracks, affecting the overall decorative effect after loading

Abstract

The invention belongs to the technical field of automobile decoration accessories and provides an automobile decoration strip which solves the problem that the existing automobile decoration strip is coarse, is liable to crack, and the like. The automobile decoration strip is arranged at corners around an automobile door window and forms a body portion and a bending portion which are integrally connected through extrusion, bending and edge cutting. The section width of the bending portion is larger than that of the body portion, and the section width gradually grows larger from the body portion and the bending position of the bending portion to a curved portion. Edge buckling portions folding inwards are arranged around the body portion and the bending portion, and sealing protection films are attached to the inner sides of the edge buckling portions. The invention further provides a method for processing the surface of the automobile decoration strip. The automobile decoration strip which is manufactured through polishing, degreasing and dewaxing, washing, surface oxidization, surface hole sealing and drying is simple in structure, convenient to install, smooth in surface and good in gloss and corrosion resistance. In addition, after the automobile decoration strip is installed on the automobile door window, the firmness is good, the quality is reliable, and the integral effect of the appearance of an automobile is improved.
