Curved Bulletproof Glass for Liftable Side Windows
Mainly compatible with special-purpose vehicles that require frequent lifting and lowering of side windows, such as police patrol vehicles, emergency rescue vehicles, and high-end commercial protective vehicles. During mission execution or daily use, these vehicles need to lift and lower the side windows to communicate with the outside world, transfer items, or ventilate. Therefore, they have extremely high requirements for the lifting smoothness, structural stability, and protection performance of the side windows.
Key Performance and Technological Breakthroughs
Guarantee of Lifting Smoothness
Through multi-curved high-precision forming technology, the tolerance between the actual outer surface of the side-window glass and the theoretical size is controlled within 1mm. At the same time, the flatness and smoothness of the glass edges are optimized, reducing the frictional resistance between the glass and the guide rails during the lifting process. This avoids problems such as jamming, abnormal noise, or difficulty in lifting, ensuring light and smooth lifting operations.
Optimization of Structural Stability
Aiming at the problem of easy interlayer stress concentration in liftable side windows during frequent movement, a special composite process is adopted to reduce the stress between the layers of the glass and the bonding materials. At the same time, the bonding strength is enhanced to ensure the structural stability of the glass during the lifting process, preventing degumming, delamination, or damage caused by vibration and friction, and prolonging the service life of the product.
Guarantee of Sealing Performance
By optimizing the matching accuracy between the glass and the guide rails, combined with special sealing materials, the side window has good sealing performance when closed. It can effectively isolate rainwater, dust, noise, etc. At the same time, the sealing structure is not easily damaged during the lifting process, maintaining long-term sealing effect and adapting to different usage environments.
Adaptation and Usage Advantages
Dimensional Matching with Vehicle Models: According to the side-window lifting guide rail structure, stroke length, and installation space of different vehicle models, the size, thickness, and surface contour of the glass are custom-designed. This ensures that the glass is always within the effective constraint range of the guide rails during the lifting process, with no deviation or jamming, and has strong adaptability.
Balance between View and Operation: While ensuring the protection performance and lifting smoothness, the optical distortion and secondary image deviation are strictly controlled. The optical distortion value is less than 1 minute of arc, and the secondary image deviation is less than 10 minutes of arc. This ensures that the driver and passengers have a clear view when observing the outside through the side windows during the lifting process, without affecting operational judgment.
