About skylights

"With a glass house, you can look up at the deep and silent night sky at night, watch the stars twinkle and watch the meteors pass through the roof." Glass houses have become the dream life of many people. As private cars enter more people's lives, it is no longer difficult to open the skylight to find the world of meteors or stars. Recently, when a car owner in Foshan talked about his newly modified skylight, his words were full of unspeakable superiority. The reporter's investigation found that in addition to the power and personalized appearance modification, installing a skylight on the roof has also become a modification behavior that many car owners are very keen on. Experts remind that private skylights are illegally modified, which will lead to changes in vehicle structure and pose great security risks. Add a skylight at least 1600 yuan. The reporter learned in the interview that the phenomenon of vehicles opening skylights privately is not a case. The reporter learned that at present, the proportion of models with skylights is about 30%, and most of the models below 6.5438+10,000 yuan are not equipped with skylights. Therefore, adding a skylight to your car has become a new idea for many car owners who pursue individuality. Some car owners even think that opening the skylight is the perfect combination of spiritual enjoyment and material enjoyment. The person in charge of Foshan Webasto skylight said that many refitters have driven cars with skylights, and the models are mainly concentrated in some sports models, such as Civic, Peugeot 307, Fit and other sports models. At present, the number of modified cars per month is above 10. Many QQ owners also like to install skylights. At present, the consumers in the refitting market are mainly male customers, and the owners who install skylights are mostly male. More male car owners believe that one of the main reasons for opening the skylight privately is that smoking is faster after smoking. According to the salesperson, having a skylight can really bring many benefits to the driver. When the vehicle is driving at a high speed, the air quickly flows out from the roof. When the skylight is opened, a negative pressure area is formed outside the car. Because the air pressure inside and outside the car is different, the dirty air inside the car can be pumped out to achieve the purpose of ventilation, so that the car can always keep fresh air and avoid the odor inside the car. Because the skylight ventilation uses the negative pressure principle, dust and sundries will not be involved when opening the skylight ventilation. In addition, the cooling effect of opening the skylight is also very good. Compared with opening the side window, as long as the skylight replaces the side window, the noise interference can be greatly reduced, and it is less affected by the speed. The reporter learned that the price of skylight modification ranges from 1.6 million yuan to 1 10,000 yuan, and the cost of installing manual skylight needs at least 1.6 million yuan, while the cost of automatic skylight modification starts from 3,000 yuan. The reporter visited a number of 4S stores and learned that these 4S stores were not found to carry out skylight modification business. The person in charge of a 4S shop said that there were fewer models with skylights in the past, and some modification companies would take the initiative to cooperate with them. With the increase of models with skylights, they will actively recommend car owners to buy models with skylights. Adding a skylight is purely fishing in troubled waters. The person in charge of a modification company in Foshan said that because there are many models, the modification technology is better now, so it is difficult to tell whether the car has been modified during the annual inspection. The relevant person in charge of Foshan Toyota said that there are many models, and many models often adopt the method of increasing the price without increasing the price. The same model may have a sunroof version and a sunroof version. The variability of this vehicle configuration provides an opportunity for private modification to fish in troubled waters. The reporter's investigation found that during the annual inspection of the car, the staff may be more concerned about whether the engine is modified or not, whether the exhaust emission exceeds the standard, and not much about whether the roof is replaced. The person in charge of a refitting shop, who did not want to be named, said that he had been refitting in Foshan for four years, and more than 500 cars had their skylights refitted. At present, he has not encountered the situation that the skylight can't pass the annual inspection because of modification. Hidden trouble: it is unsafe to add windows after modification. Industry experts remind consumers that opening the skylight privately will not only affect the annual inspection, but also bring safety hazards such as quality. The rigidity of the whole vehicle is greatly weakened. Lai Junhui, the after-sales person in charge of Guangben Baoxing, said that motor vehicles with skylights are generally equipped with high-priced transverse and longitudinal beams when they leave the factory to ensure the safety and technicality of the vehicles. Private skylight will change the overall structure and safety performance of the original car. If a hole is added to the roof, the structure of the whole vehicle will be destroyed, the rigidity of the vehicle will be greatly weakened, and the safety is much lower than that of the vehicle without skylight. At present, the quality of skylights on the market is uneven, and the risks that may be formed after modification are incalculable. It is reported that every car must go through trial run and collision test before it is finalized, and it can only be produced and sold after it has passed the inspection by the national quality and technical supervision department. If there is no collision, it is difficult to ensure the protection of people in the car. Poor sealing will corrode the roof. In addition, if the modification is not good, it will also cause problems such as skylight leakage and roof corrosion. "Installing a skylight requires very accurate calculation, and waterproof problems alone require high technical difficulty." Chen Peihua, the person in charge of the modification of Foshan Hong Ling, pointed out, "In addition, the calculation of safety factor of safety car needs to be considered according to the parameters of different materials and different radians designed by manufacturers." The private skylight destroyed the structure of the top of the vehicle, so it is difficult to ensure the sealing performance in ordinary installation, resulting in water leakage in the vehicle and roof corrosion. Reminder: It is not only unsafe but also illegal to open the skylight after buying a car. According to the Road Traffic Safety Law of the People's Republic of China, no unit or individual may engage in the following acts: assembling a motor vehicle or changing the registered structure, structure or characteristics of a motor vehicle without authorization. At the same time, when a registered motor vehicle carries out safety technical inspection, if the registered contents recorded in the motor vehicle driving license are inconsistent with the relevant situation of the motor vehicle, it will not pass the inspection. Unauthorized modification of the skylight is an unauthorized change of the registered structure, structure or characteristics of the motor vehicle, and the registration content recorded in the motor vehicle driving license is inconsistent with the relevant situation of the motor vehicle, which is a prohibited act. In Europe and America, it is illegal to open the skylight by yourself, because such modification will destroy the original structure of the car, and if an accident occurs, it will be an unsafe hidden danger. Lai Junhui said that the manufacturer's models with skylights are generally only 8,000 ~110,000 yuan, and leather sofas are also added. Adding a skylight alone is prone to risks such as water leakage and reduced safety factor. It is recommended that consumers who like skylights buy original models with skylights.
