【Car owner's car knowledge】Car sunroof has always been one of the interest points of car consumers when buying a car. Whether a car has a sunroof or not is likely to be the basis for distinguishing the model version of a car, so how do car owners maintain the sunroof? Does the skylight only have the function of ventilation or pulling the wind? Today, I will analyze the maintenance and use methods of car sunroofs, and let everyone know how important car sunroofs are to car owners.
Start with the subtleties
The car sunroof is installed on the top of the car and is generally mainly composed of a glass window, a sealing rubber strip and a driving mechanism. It uses the principle of negative pressure ventilation, relies on the rapid flow of airflow on the roof of the car when the car is driving to form a negative pressure, and draws out the dirty air in the car, so that the air inside and outside the car flows, completes the conversion of air, and filters the car. inner air.
Many car owners know the importance of the sunroof, and some car owners who like DIY want to complete the maintenance work by themselves, so how to maintain the sunroof? The maintenance of the sunroof by yourself is actually very simple: you can fully open the sunroof, first use a clean soft Wipe the dust on the slide rail with a cloth; then use a lubricant that is not easy to absorb dust to lubricate the slide rail part and the transmission pipe of the sunroof.
In addition, daily special attention should be paid to the dustproof work of the sunroof sealing ring. In spring and autumn, you can clean the sealing ring with a damp sponge every other season. Before the vehicle is parked for a long time, the sunroof should be thoroughly cleaned with talcum powder to avoid the natural aging of the rubber strip due to chemical changes in the air for too long.
When washing the car at ordinary times, it is necessary to check the rubber strips and grooves of the sunroof for dust, leaves or twigs and other dirt. When using a high-pressure water gun to wash the car, do not directly spray water on the sealing ring around the sunroof, otherwise the sealing ring will be easily deformed under the spray pressure of the high-pressure water column, and water will easily enter the car after a long time.
One thing that car owners can't do DIY is to find the blocked drain pipe. Because the design of the drain pipe is relatively hidden, it needs to be disassembled by professionals to find it. Therefore, this link needs to be repaired in the factory.
specific tips
The car sunroof has improved the grade of the vehicle, but most consumers do not understand the sunroof. The master of the 4S shop gave us the following tips.
Firstopening the sunroof when driving is smaller than opening the side windows, so the sunroof can be opened at medium speeds to avoid increasing fuel consumption.
second, in the rainy season, the skylight can be used to quickly remove the fog. In the southern summer and autumn and other seasons with more rain or a large temperature difference, if the windows are tightly closed during driving, it will cause a temperature difference between the inside and outside of the car, and the front windshield and side windows are prone to fog. If you open the sunroof to speed up the air convection in the car, you can quickly eliminate the fog in the front windshield.
thirdWhen the vehicle is parked in the sun for a period of time, the temperature inside the car will be as high as 50~60 ℃. At this time, as long as the car sunroof is opened, the negative pressure formed during the driving of the car can be used to extract the hot air, which can quickly cool down.
In addition, when a traffic accident occurs, if the door is squeezed and deformed and cannot be opened, as long as it is not a rollover accident, the sunroof can be used as an effective escape route.
