(Summary description)Car door and window glass should not only ensure that the driv±er has sufficient perspective to safely drive and drive;  At the same time, in order to meet the needs of riding comfort→, the position of the glass often needs to be adjusted, so the  range of glass adjustment and the flexibility and convenience of operatγion become important performance indicators. The mechanism that ensures flexible adjustment§ of car windows is the window regulator, which is also an important component for c≈ar safety and comfort.
Structure and characteristics of car window regulator
In 1981, China implemented the JB2882-81 "Technical Conditions 8 Standard for Glass Lifts f♣or Heavy Duty Vehicles". Based on this standard, and based on the manufacturing, use, ×and testing situation of glass Lifts for automobiles in China, and referring to relevant₽ international advanced technical indicators and data, the automotive industry ≈standards QC/T29026-91 "Test Methods for Glass Lifts for Automobiles" and <QCT29027-91 were revised and formulated The "Technical Conditions for Automotive G∏lass Lifter" was promulgated and implemented in 1991, which clearly stipulates th↔e basic technical performance and testing methods of automotive gl​ass lifters. Due to the widespread use of arm type glass lifters in China, other types, especialσly flexible glass lifters, lack relevant technical information and data. Theγrefore, the above standards are only applicable to δarm type glass lifters, and other types of glass lifters The descent devi₽ce can also be executed as a reference.
Due to the relatively simple manufacturing process and low cost of arm tyαpe window regulators, about 80% of car window regulators in China currently use arm type ✘window regulators. The flexible glass regulator is much more comp∞act in terms of stability and motion resistance, and is more convenient to install and arrange. ΩHowever, there is currently no official national standard for flexib£le glass regulators in China.
The flexible shaft type window regulator has been widely used in v'arious high-end vehicles, especially sedans, around the wφorld, and is a relatively advanced type of window regulator. In recent years, imported autom↓otive products in China, such as CNHTC Steyr, Beijing Cherokee, and Nanjin g Iveco, have all adopted this type of opening and lowering device. Currently, some automotiv↕e parts factories in China, such as Beijing Automotive Window Lifter Factorεy, Nanqi Vehicle Tool Factory, and Sichuan Automotive Factory Accessor∏y Factory, have completed the technical development (introduΩction) of the production process for flexible shaft glass regulators, providing domestically prod¥uced products. With the improvement of their mass production level, It •can also be used as an alternative to arm type window regulators.
Due to the requirements of automotive structural layout design, manufa§cturing costs, and manufacturing technology, manual push-pull winβdow adjustment mechanisms are still used in many vehicles. At present, arm and manual (me→chanical) window regulators are the main types of use, while the appl≠ication of flexible window regulators is still limited to imported models, while the appliγcation of electric window regulators is relatively limited.
The application of electric window regulators in mid to high-end ♣cars abroad is already very common. However, due to its complex structure, high cost, and unstabΩle performance of small motor products in China, its application in automotive prodαucts in China is still limited. It can be foreseen that with the improvement of China's a₹utomotive design and manufacturing level, electric window regul​ators will be increasingly applied to automotive products.
