Principle of car sunroof

      The structure of the car sunroof mainly includes the sunroof drive motor system, glass combination and sliding mechanical structure. The sunroof drive motor system is composed of components such as the motor, transmission system and sliding screw. The motor provides power for the opening and closing of the sunroof through the transmission system. Its rotation direction can be adjusted by changing the direction of the current, thereby realizing the opening and closing function of the sunroof. The sliding system is composed of core components such as guide blocks, guide pins, connecting rods, brackets, and front and rear pillows. These components jointly support the sliding of the glass. 

1、Negative pressure ventilation principle:

    According to Bernoulli's principle, when the car is driving, the air velocity outside the car body is high and the pressure is lower than that inside the car. After opening the sunroof, a negative pressure area is formed outside the car, and the air inside the car will be drawn out. At the same time, filtered fresh air is added from the air inlet to achieve efficient ventilation and ventilation, which can quickly update the air inside the car and keep the air fresh.

2、Electric drive principle:

        The opening and closing of the car sunroof mainly depends on the electric drive system. Through the sunroof switch control circuit, current is transmitted to the drive motor, and the motor operation drives the transmission mechanism, which in turn drives the sunroof glass to move on the track to achieve various actions of the sunroof, such as sliding open, closing, inclined rise, inclined fall, etc.

3、Sliding track system:

          The sliding system of the electric sunroof is mainly composed of core components such as guide blocks, guide pins, connecting rods, brackets, and front and rear pillows. These components work together to ensure the smooth sliding of the sunroof.

4、Control module:

      The control module is a digital control circuit that integrates functions such as timer, buzzer and relay. It receives information from the switch   input, performs logical operations through digital circuits, determines the action of the relay, and thus controls the opening and closing operation of the sunroof.
