1. What are the types of car sunroofs?
1. Built-in sunroofs
This is the most common The skylight structure has two opening methods: outward tilting and full opening, which can be said to be diverse in function. The outward tilt is the most commonly used. It can only open a gap and cannot be fully opened. Its function is to ventilate. Through the negative pressure effect, the air in the car is quickly sucked out of the car without causing too much noise and turbulence.
If you want to open it all, you can only slide it back and forth in the sunroof track. This function seems practical, but its frequency of use is very low. However, it is still possible to escape if you fall into the water. However, this type of sunroof will be hidden in the roof mezzanine, so the headroom in the rear row will be smaller.
2. External sliding sunroof
The installation of this type of sunroof may be due to the small space in the car, the large curvature of the roof or the structure of the roof, etc. For this reason, the skylight cannot be stored in the mezzanine. This way of opening the sunroof rises diagonally to the rear, which does not sacrifice the interior space of the car, and has advantages in structural cost and other advantages over the built-in type. However, this design cannot be fully opened, and it will increase the car’s wind resistance coefficient and make relatively loud noise.
3. Closed large-area sunroof
This type of sunroof is also commonly known as the canopy. This type of sunroof has a large area, making it easy for passengers in the front and rear rows to Both can have a good lighting effect. This kind of skylight has a good sense of space, but its roof has poor bearing capacity, and it cannot be opened. It can only be seen but not ventilated. Car owners who need ventilation need to consider carefully.
4. Segmented electric sunroof
Strictly speaking, this kind of sunroof is not a panoramic sunroof. It adds a crossbeam in the middle to divide the window. It is divided into two parts: front and back. In this way, there will be good lighting effects in the front and back, adding fun to the trip. The roof’s bearing capacity is also stronger than that of the panoramic sunroof. The most important thing is that the front sunroof can be tilted and slid outwards.
5. Openable panoramic sunroof
Although the area is not as large as the segmented sunroof, it can be tilted outwards and fully opened, and its The lighting effect is also good, and it can take into account the passengers in the front and rear rows, but its roof area must be large and flat.
2. Is it necessary to buy a car sunroof?
Whether to buy a car sunroof or not depends on the car owner.need. Some car owners think that car sunroofs are very convenient and have many advantages, so it is necessary to equip them. Some car owners think that car sunroofs are of little use and there is no need to equip them with sunroofs when buying a car.
1. Advantages of car sunroofs
First of all, some people may think that there are only four side windows in the car. It looked rather dark, and the atmosphere in the car was quite depressing. After opening the sunroof, the overall field of vision in the car is expanded, and you can see further while sitting in the car.
There are also a small number of people who may have symptoms such as claustrophobia. If you don’t open the sunroof, you may feel that staying in a car in such a small environment will be uncomfortable. It’s airtight and makes people feel uncomfortable.

2. Disadvantages of car windows
After a sunroof is installed in a car, it needs to be maintained frequently. If the skylight is not maintained regularly, the skylight may get stuck when it is closed, especially when it rains heavily, it will become very troublesome.
At the same time, after opening the skylight, some leaves and branches may fall into the gaps in the skylight track. If these branches and leaves are not cleaned in time, they may get stuck inside, causing the skylight to fail to close. superior.
Similarly, after installing a skylight, we also need to clean and clear the drainage holes of the skylight regularly. If the drainage holes of the skylight are blocked, it will cause the skylight to leak.
Secondly, the sunroof is a thin curtain, and the thermal conductivity of the glass outside the car window is also relatively strong. When the sun is very strong, the sun may shine through the sunroof and into the car, causing damage to the car. The temperature inside the car will rise, and people in the car will feel very hot and uncomfortable. The air conditioner needs to be turned lower to reduce the temperature inside the car. At the same time, buying a sunroof when buying a car also requires a high cost. .
In the event of a traffic accident, since the skylight is made of glass, its hardness and thickness cannot be compared with that of steel, which may cause safety hazards.
Summary: If you can accept the small environment in the car and don’t have the habit of smoking frequently, buying a sunroof doesn’t make much sense. But if you are a habitual smoker and the local air quality is relatively good, you can buy a car sunroof.Behind the window, the skylight must be maintained regularly.
