Panoramic automobile skylight

Abstract

The invention discloses a panoramic automobile skylight comprising a skylight outer frame, sliding rails arranged at both sides of the skylight outer frame, and an automobile skylight glass arranged on the sliding rails in a sliding mode. The automobile skylight glass is driven and controlled by a stepping motor to enable the automobile skylight glass to slide along the sliding rails; the automobile skylight glass comprises a first glassy layer and a second glassy layer, a middle glassy layer is installed between the first glassy layer and the second glassy layer, a temperature sensing color changing film layer is installed between the first glassy layer and the middle glassy layer, and a heat preservation film coating layer is installed between the second glassy layer and the middle glassy layer; the middle glassy layer is internally provided with a cavity channel, a ventilation duct is installed in the cavity channel, an air inlet end of the ventilation duct is connected with a warmair machine, and multiple riser vents are formed in the outer wall of the ventilation duct. Dazzling hard light and dazzle light can be avoided through the temperature sensing color changing film layer, and fog generated on the first glassy layer and the second glassy layer can be avoided through the ventilation duct.

Description

technical field [0001] The invention relates to the technical field of automobile sunroofs, in particular to a panoramic automobile sunroof. Background technique [0002] The car sunroof is installed on the roof of the car. The car sunroof ventilation means that when the car has a driving speed, the air flow speed inside the car will be lower than the air flow speed outside the car, thereby forming a pressure difference of the air flow, and the air flow inside and outside the car will be exchanged, so it is It can be ventilated. The sunroof of the car is installed on the roof. When the car is running at high speed, because the roof of the car has a certain curvature, the speed of the external airflow will be very high when it flows through the roof of the car, and the pressure of the external air on the roof of the car will be lower than that of the car. The pressure of the inside air on the roof of the car, the air inside the car flows outside the car, the pressure becomes...

Problems solved by technology

[0003] The current car sunroof has a single function, and the sunroof does not have the function of defogging. In winter, because the hot air in the car encounters the cold car sunroof, at this time, the temperature inside the car window is low, and the hot air will be cold when it is cold. Condensate into small water droplets or water mist on the glass. At the same time, the current car sunroof often needs to control the change of light through the electronic film layer to achieve the purpose of discoloration. However, this kind of car sunroof is expensive and the manufacturing process is complicated, which is not conducive to popularization and use.
