A car sun visor is a sun visor installed above the main and co-pilot. Its main function is to block out harsh sunlight. You must know that the dazzling sunlight can be called a "street killer", especially when traveling in summer. The "dazzling" sunlight is likely to pose a threat to the safety of drivers and passengers. This is not groundless. According to statistics, there have been tens of thousands of traffic accidents caused by harsh sunlight. The sun visor can be very clever to avoid direct sunlight. Not only that, the connection of the car sun visor is even more "hidden mystery". In fact, one of the two fixed parts of the car sun visor can be disengaged and the other can be rotated. That is, car sun visors can be used to block the sunlight coming in from the side windows. In addition, most of the sun visors now have vanity mirrors, which is an additional feature that provides convenience for travelers.

Car sun visors can be divided into three types: front, side and rear. Although this principle of the sun visor can suppress the temperature rise in the car in a short time, after all, the environment in which it is located has not changed. All parts of the car will conduct heat, and the temperature in the car will still rise after a long parking time. The little visor has changed. However, this sun visor is not completely useless. The reason is that if there is no sun visor, the sun will directly enter the car and cause the temperature of the center console to rise to more than 60 degrees. If there is this sun visor, most of the The heat will be absorbed by the sun visor, and the temperature of the interior will be the same as the temperature inside the car.

From this, we can conclude that: although the car covers will not alleviate the temperature rise in the car if the car is placed for a long time, the sun visor will play a role in reducing the temperature rise of the interior and alleviating the aging of the interior. The other is the sun visor installed above the driver to prevent the sun glare. If your driving route to work is in the east direction around 6-7 in the morning, you can use the sun visor just against the morning sun! So the car Sun visors can still play an important role while driving.
