For the overall stiffness of the car body, the top cover is not a very important component, which is also the reason for allowing a sunroof on the roof cover. For the overall stiffness of the car body, the top cover is not a very important component, which is also the reason for allowing a sunroof on the roof cover. From the design point of view, the important thing is how to smoothly transition with the front and rear window frames and the junction point with the pillar, so as to obtain the best visual sense and minimum air resistance. Of course, for the sake of safety, the roof cover should also have a certain strength and stiffness. Generally, a certain number of reinforcing beams are added under the top cover, and the inner layer of the top cover is laid with thermal insulation liner material to prevent the conduction of external temperature and reduce the transmission of noise during vibration. classification The roof cover is usually divided into fixed top cover and convertible top cover. The fixed top cover is a common form of car top cover, which belongs to a large covering with large outline size and a part of the overall structure of the car body. It has strong rigidity and good safety. It plays a role in protecting passengers when the car rolls over. The disadvantage is that it is fixed, has no ventilation, and can not enjoy the fun of sunshine and driving. The convertible top cover is generally used on high-grade cars or sports cars. By moving part or all of the top cover through electric and mechanical transmission, you can fully enjoy the sunshine and air and experience the fun of driving. The disadvantage is that the mechanism is complex and the safety and sealing performance are poor. There are two forms of convertible top cover, one is called "hardtop", and the movable top cover is made of light metal or resin material. The other is called "soft top", and the top cover is made of tarpaulin. characteristic The components of the hardtop convertible are matched very accurately, and the whole electric control mechanism is complex. However, due to the use of hard materials, the sealing performance after restoring the compartment top cover is good. The soft top convertible is composed of tarpaulin and support frame. The open carriage can be obtained by folding the tarpaulin and support frame back. Due to the soft texture of the tarpaulin, the folding is relatively compact, and the whole mechanism is relatively simple, but the sealing and durability are poor.
