Description

Technical Field

[0001] The invention relates to the technical field of sunroof marks, and in particular to a replaceable high-strength, high-toughness, wear-resistant and corrosion-resistant vehicle sunroof mark. Background Art

[0002] The car sunroof provides passengers with additional views and ventilation options. It allows more natural light to enter the car, making the interior brighter, which helps improve the mood of the driver and passengers. At the same time, opening the sunroof can increase air circulation in the car, especially when driving at low speeds. Natural convection can be formed through the sunroof to improve the air quality in the car. In certain emergency situations, the sunroof can be used as an emergency escape exit. For some people who like outdoor activities, vehicles with sunroofs can provide a better driving experience, such as viewing the stars and enjoying the sunshine.

[0003] Generally, stamps are used on the guide rails of car sunroofs to mark relevant information on the sunroof, or sunroof stamps are used to mark the sliding positioning information of the sunroof on the guide rails. However, the conventional sunroof stamps are completely fixed in position and difficult to change accordingly. In addition, the conventional sunroof stamps are easily damaged by friction on the guide rails due to their insufficient rigidity, which greatly affects the marking effect of the stamp. Therefore, there is an urgent need to design a replaceable, strong, flexible and wear-resistant car sunroof stamp. Summary of the invention
