TECHNICAL FIELD
[0001] The application relates to the technical field of automobile sunroof frames, in particular to a light-weight sunroof frame structure. BACKGROUND
[0002] A sunroof is one of the configurations preferred by many consumers, and a vehicle equipped with a sunroof is often more popular in the market. The sunroof is generally composed of a glass, a sunroof frame and a control system, etc. The sunroof frame is an important component on the roof of a sunroof vehicle, and is fixedly installed at a sunroof opening of the roof by a mushroom buckle. The roof is provided with a protrusion, and the sunroof frame is located between the sunroof opening and the protrusion.
[0003] At present, the sunroof frame of an automobile is mostly made of metal material, especially iron material, and has a quadrangular frame shape. The sunroof frame has no rib at a corner, and the sheet metal joint has no welding point. The force transmission path is poor, resulting in poor structural strength and rigidity. In a side impact performance test, the corner is often crushed first. The sunroof frame structure has low stability. In addition, the iron sunroof frame is heavy, which not only increases the overall weight of the vehicle, affects fuel efficiency and maneuverability, but also, due to the action of gravity, may cause the mushroom buckle and other connecting structures of the roof at the sunroof part to move downward, affecting the appearance consistency of the roof. CONTENT OF THE UTILITY MODEL

[0016] Optionally, the sunroof strip is provided with a mounting boss, and the mounting boss is provided with a plurality of fixing holes.
[0017] By adopting the technical scheme, the mounting boss and the plurality of fixing holes thereof provide a stable platform for the installation of mushroom buckles, allowing reliable connection between the sunroof frame and the roof, and improving the stability and reliability of the overall structure.
[0018] Optionally, the wrinkle absorbing rib penetrates the mounting boss.
[0019] By adopting the technical scheme, the design of the wrinkle absorbing rib penetrating the mounting boss allows the sunroof strip to effectively absorb and disperse impact energy when subjected to external impact, improving the impact resistance of the overall structure. At the same time, the connection strength between the sunroof strip and the roof is enhanced, the stability and reliability of the sunroof frame during vehicle driving are improved, and the service life of the sunroof frame is prolonged.
