When buying a smart car window product, there will be a lift function or other special functions in the introduction of the functional configuration. What is the difference between the lift function and the traditional window lifter, which one is better when buying? We can analyze it in terms of features, price and installation. One. Function: Compared with the traditional products that only have the function of locking the window of the car, in addition to the window can be lowered by remote control, most manufacturers will increase the suspension of work during the lifting process and the intelligent retention of the four windows, and even increase the one-button lift of the four windows. The window (AUTO) can be described in a variety of functions. two. In terms of price: the lifting window has many functions and high cost. In addition to the wiring harness and motherboard components being more complicated than traditional window lifting devices, the research and development cost will be higher, so most brands will price the lifting window higher than the single lifting window Out a lot. three. In terms of installation: The traditional window lifter was listed earlier, and has developed from an early universal full-wiring to a special plug-in product for special vehicles. The wiring of most products is relatively simple. Compared with the traditional window lifter, the lifting window product is not complicated in terms of wiring. Conventional models only have one "central control unlocking belt with instant positive wire". There is no essential difference between the two installation methods. four. Product stability: In addition to the direct relationship between product performance and workmanship and materials, the functional category of the product also has an impact. The more functional the product, the higher the probability of failure. Selection suggestions: I recommend that when you choose a product, you must purchase a product suitable for the vehicle in accordance with your actual needs, and you cannot buy a multifunctional product because of the promotion of the merchant. To comprehensively consider the installation and after-sales terms, you can buy the product you are satisfied with.

With the development of the economy, the popularity of automobiles is getting higher and higher, and vehicle safety has become a concern for many car owners. The installation of automotive electronics has become one of the necessary equipment for many car owners. In view of the fact that most vehicles are not equipped with intelligent control windows when they leave the factory, the intelligent window lifter is designed to improve vehicle safety and prevent the loss of property in the car or the rain or snow due to the failure to close the window after the car is locked. Tianjinshui's products have naturally become one of the hottest automotive electronic products on the market. At the same time, many car owner friends will have such doubts before choosing to install the smart window lifter. Will this product affect the vehicle's line safety and maintenance? Let's start with the installation of smart window lifters. Due to the different working methods of the window control system when vehicles from various manufacturers leave the factory, and in order to facilitate installation, the current smart window lifters on the market are dedicated products for special vehicles. According to the installation method and the composition of the product hardware, we can classify them into two types: OBD computer detection port plug-in type and original car transfer plug-in type. The CAN bus protocol communicates with the original car computer. When the vehicle lock signal and unlock signal are received, the original car computer sends work instructions to the window system, and the original car system completes the automatic window-up, window-down and other functions. The main features of this type of product are: 1. Easy installation, just plug directly into the OBD computer detection port, without disassembling the vehicle, just start the vehicle once. 2. Compatible with the original car system program and dual use, will not affect other functions of the original car. 3. Using high-precision components, it only needs to send signals to the original car system, and the product consumes very low power. 4. Can be reused. When the vehicle needs to use the original car inspection port, it can be pulled out and plugged in again. This type of product is mostly used in European and American models, such as Shanghai GM, Audi, BMW and other models are mostly this type of product. The original car transfer plug type is installed in the position of the original car window control switch. The principle is to directly install a control host through the original vehicle adapter plug. When the vehicle lock signal and unlock signal are received, the host triggers or directly supplies power to the window lift motor to complete the automatic closing or lowering of the window. The main features are: 1. Special connector for the special car, the interface can match the original car, will not damage the original car line, and greatly reduce the tedious wiring and wiring. 2. When the product is in non-working state, the host is in a low-power sleep state, and the vehicle will not suffer from power loss. Only when it receives the central control lock signal will it wake up again. 3. It will not interfere with the functions of the computer ECU or other components of the original car. The products are installed in the glass control circuit, most of them are in the door, and the main components such as the instrument in the car are in different positions and circuits. 4. Anti-overload protection. The main board of the window lifter is equipped with a power protection circuit. At the same time, the product has a fuse. The fuse specification is lower than the original car glass window fuse. When the current overload or short circuit occurs, it will blow first to protect the original car circuit. Affected. Therefore, the installation of the smart window lifter will not affect the car. In addition, according to relevant laws and regulations after the installation of the smart window lifter, 4S stores still have to perform the maintenance and repairs agreed upon when purchasing the car. The owner can enjoy the national regulations. Warranty policy. However, because the smart window lifter is a retrofitted product, there are certain requirements for the quality of the product and the installation technology. Therefore, it is also recommended that the majority of car owners, when buying products, we must pay attention to the brand, try to choose a good reputation, quality and reliable brands, manufacturers with strong research and development production capacity, but also to find technically qualified modification personnel, not because of the price Cheap or false propaganda causing unnecessary losses.
