Automobile sun shielding board with large mirror surface cosmetic mirror

Abstract

The invention provides an automobile sun shielding board with a large mirror surface cosmetic mirror. The automobile sun shielding board with the large mirror surface cosmetic mirror comprises a mirror surface EPP, a framework sub assembly and a back surface EPP, wherein the mirror surface EPP, the framework sub assembly and the back surface EPP are sequentially connected, a cosmetic mirror assembly is arranged on the framework sub assembly, and the framework sub assembly comprises an abnormal shaped aluminum tube, an injection molding framework, an annular steel wire framework and a front plug. The automobile sun shielding board with the large mirror surface cosmetic mirror is characterized in that the cosmetic mirror assembly comprises a large mirror surface cosmetic mirror body, a mirror frame and a decorative frame, and the decorative frame, the mirror frame and the injection molding framework are sequentially connected. The large mirror surface cosmetic mirror body and a roller shutter device are arranged in the mirror frame, a plurality of cosmetic mirror buckles are arranged on the back surface of the mirror frame, a plurality of decorative frame buckles are arranged in themirror frame, and a plurality of decorative frame buckle slotted holes are formed in the back surface of the decorative frame. A PCB is fixedly connected to the side surface of the mirror frame, an abnormal shaped aluminum tube extension structure is arranged on the lower part of the abnormal shaped aluminum tube and fixedly fixed to the injection molding framework, a honeycomb mesh-shaped enhancing structure is arranged on the injection molding framework, and a weaken energy absorption structure is arranged beside a hook shaft of the injection molding framework.

Description

technical field [0001] The invention relates to an automobile sun visor, in particular to an automobile sun visor with a large cosmetic mirror. Background technique [0002] Self-driving car technology is the current development trend of the automotive industry. The roof-mounted airbag of the self-driving car is located above the sun visor of the car. The sun visor must not only be able to withstand the impact force of the normal deployment of the airbag after it explodes, but also be able to withstand the higher impact load when the airbag is deployed. [0003] At present, the visible area of ​​cosmetic mirrors on car sun visors is relatively small (the area of ​​cosmetic mirrors accounts for 15% to 20% of the total area of ​​sun visors). About 40% of the total area), which can increase the visual area of ​​passengers and improve the comfort of passengers when they see. However, increasing the viewing area of ​​the vanity mirror will weaken the structure of the sun visor ...

AI Technical Summary

Problems solved by technology

However, increasing the viewing area of ​​the vanity mirror will weaken the structure of the sun visor body, reduce the impact resistance of the sun visor structure, and increase the fragility of the vanity mirror lens, causing many potential safety hazards. After the airbag blasts, the vanity mirror lens is the most easily broken part after being impacted, and the flying debris will cause secondary damage to the occupants of the car

The blasting test was carried out after increasing the visible area of ​​the vanity mirror on the existing sun visor structure. The sun visor had a series of problems such as the aluminum tube falling off the frame, the support shaft flying out, and the lens being shattered and broken.
