[0028] Specific references Figure 1 As a vehicle with a large arc side window according to the present invention, the device includes: a vehicle body, high-strength laminated glass 110, and a sealing structure; the high-strength laminated glass 110 includes a convex surface 111 and a flat surface 112, the convex surface 111 being the front half of the high-strength laminated glass, and the flat surface 112 being the rear half of the high-strength laminated glass, the radius of the convex surface 111 being much smaller than the radius of the flat surface 111, forming a large arc shape; the sealing structure includes a sealing strip 121 and auxiliary sealing measures (sealant 122, drainage groove), which are wrapped around the edge of the side window at the connection with the vehicle body.
[0029] In this specific embodiment, the present invention uses a hot bending process to form a high-strength laminated glass with a large arc shape, combined with a EPDM rubber sealing strip (and a sealing structure of sealant and continuous groove drainage channels), to achieve seamless integration with the streamlined design of the vehicle body, widen the lateral field of vision of the driver and passengers, utilize PVB film to improve sound and heat insulation performance and prevent shattering, and prevent rainwater from seeping into and corroding the vehicle body, thereby significantly improving the aesthetics of the car's appearance, driving comfort and safety.
[0030] In this example, the high-strength laminated glass 110 includes a convex surface (radius of curvature R1) on the front side and a flat surface (radius of curvature R2) on the rear side, wherein the radius of the convex surface R1 is much smaller than the radius of the flat surface R2 (for example, R1≤R2 / 5). The outer convex surface maintains a distance of 5-10mm from the side wall of the vehicle body, which not only meets the requirements of streamlined design, but also reserves installation space for the sealing structure, forming a streamlined shape with a convex front and a gentle rear.
[0031] In this example, the glass consists of at least two layers of glass with a polyvinyl butyral (PVB) film sandwiched between them, which improves impact resistance and sound insulation performance; and the large curvature shape is optimized by finite element simulation to match the side window of the MPV model, with the curvature radius tolerance controlled within ±0.5%, ensuring a high-precision fit with the body surface.
[0032] In this example, the sealing strip 121 is made of EPDM rubber and is located on the outer edge of the window. Its cross-section is "L" shaped, which fits tightly against the gap between the body and the edge of the side window. It is fixed to the body window frame and side window glass through a slot structure to prevent the sealing strip from falling off when driving at high speed.
[0033] In this example, sealant 122 is applied to the inside edge of the window with silicone sealant to fill tiny gaps and enhance sealing performance.
[0034] In this example, a drainage channel with a continuous groove structure is provided at the bottom edge of the side window, extending along the bottom of the side window and connecting with the body's drainage channel. When rainwater seeps in, it can be quickly discharged to avoid corroding the body.
[0035] In this example, positioning holes 130 are made at the four corners of the side window. The positions of the holes match the reserved holes on the vehicle body. The windows are fixed with bolts, and rubber gaskets are placed inside the bolt holes to prevent water leakage.
[0036] In this example, the groove of the fixed sealing strip is provided with anti-slip texture. The anti-slip texture adopts a triangular raised array, which can increase the friction coefficient between the fixed raised strip and the groove, and prevent the sealing strip from falling off due to vibration or external force. The large arc shape is determined by finite element analysis simulation to match the arc of the side window of mainstream MPV models on the market. For example, the side window convex radius of a certain brand of MPV is designed to be 800mm and the plane radius is 2000mm, ensuring seamless connection with the streamlined design of the body.
[0037] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
