Moreover, the skylight is installed on the roof, which can effectively circulate the air inside the car, increase the intake of fresh air and bring healthy and comfortable enjoyment to the owner. At the same time, the window can also broaden the field of vision, and is often used for the shooting needs of mobile phone photography. Automobile skylights can be roughly divided into: external sliding type, internal hiding type, internal hiding type and external turning type, panoramic type and curtain type. Mainly installed in commercial SUVs, cars and other models. Since 1936 obtained the first patent for automobile sunroof, now Webasto has more than 60 patents for sunroof, with a market share of 65% in the field of automobile sunroof, and has become synonymous with high-quality sunroof.
Type: At present, the popular panoramic skylight is divided into two independent special glass structures, so that the front and rear seat members can enjoy the feeling of skylight respectively. The other is that the whole roof is skylight. There are full-open, half-open or full-closed opening modes.
Distinguish:
1. Ordinary skylights only "take care" of the front (driver's seat or co-pilot).
2. Compared with ordinary skylights, panoramic skylights have a wider field of vision and good ventilation.
3. Panoramic skylight has high manufacturing cost, while ordinary skylight has low manufacturing cost.
4. Panoramic skylight is difficult to "take care of or maintain", and it is often necessary to clean up dust or other foreign objects, otherwise it will affect the beautiful appearance or affect the line of sight because of blocking foreign objects, and even affect the mood of enjoying sunshine.
5. Panoramic skylight is difficult to maintain, and its "safety factor" is obviously lower than that of single skylight (or ordinary skylight).
6. Panoramic skylights are divided into fully enclosed, semi-open and fully open, and fully open panoramic skylights are rare, generally concentrated in high-end car series. The ordinary skylight has a single function.
7. Panoramic skylights require much higher glass in terms of technical parameters than ordinary skylights. If they are subjected to external force, their stress area or scope is wider and larger than that of ordinary skylights, so they are slightly inferior to ordinary skylights in this respect.
