[0023] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0024] The present invention relates to a rear-mounted fixed window for vehicle doors, such as... Figure 1-7 As shown, the device includes glass 1, guide rail 2, and sealing strip 6. The glass 1 is made of automotive-grade tempered glass, which is cut and shaped according to the size of the fixed window of the car door. The edges are then polished to remove burrs and sharp corners. The periphery of the glass 1 is injection molded with a rubber coating 5, which is made of TPE or PVC soft rubber material. The rubber coating 5 is L-shaped and partially surrounds the edge of the glass 1, thus ensuring a stable fit between the glass 1 and the rubber coating 5.

[0025] The coating 5 has a connecting part 7 located at the sharp corner of the glass 1. The connecting part 7 and the coating 5 are integrally formed. The connecting part 7 and the sealing strip 6 are injection molded together by inserts, which can improve the sealing performance and structural integrity. The sealing strip 6 and the coating 5 are equipped with guide rails 2.

[0026] As per the material specification of guide rail 2, guide rail 2 is a metal guide rail, preferably made of aluminum alloy.

[0027] As a preferred embodiment of the rubber coating 5, a limiting bracket 9 is provided on the lower side of the rubber coating 5, and a nut 10 is provided on the limiting bracket 9. A through hole 11 is provided on the guide rail 2 at the position corresponding to the nut 10. A screw that is threaded to the nut 10 is installed at the through hole 11. By passing the screw through the through hole 11 and threading it to the nut 10, the Z-direction limiting of the guide rail 2 is achieved.

[0028] The lower side of the rubber coating 5 and the limiting bracket 9 are injection molded together by inserts.

[0029] The limiting bracket 9 is a metal bracket or a plastic bracket, and the nut 10 is a conical nut, which is fixed to the limiting bracket 9 by insert injection molding or welding.

[0030] As an installation instruction for the guide rail 2, the guide rail 2 is slidably snapped together with the connecting part 7 and the sealing strip 6. The guide rail 2 has an assembly groove 12, and the connecting part 7 and the sealing strip 6 slide into the inner wall of the assembly groove 12.

[0031] As a structural description of the guide rail 2 snap-fit ​​assembly, snap-fit ​​protrusions 13 are provided on both sides of the opening of the assembly groove 12, and the rubber coating 5 is provided with a slot that cooperates with the snap-fit ​​protrusions 13; the rubber coating 5 achieves the quick assembly of the guide rail 2 through the sliding cooperation between the snap-fit ​​protrusions 13 and the slot.

[0032] As a preferred embodiment of the connecting part 7, a stop bar 8 is provided at the end of the connecting part 7. The stop bar 8 is engaged with the end of the guide rail 2 to further restrict the relative displacement of the guide rail 2 and improve the assembly reliability.

[0033] Assembly process of guide rail 2: Align the assembly groove 12 of guide rail 2 with the sealing strip 6 and the connecting part 7, and slowly slide it in along the inner wall of the assembly groove 12 so that the slot on the rubber coating 5 slides and engages with the snap-fit ​​protrusions 13 on both sides of the assembly groove 12 until the stop strip 8 at the end of the connecting part 7 is engaged with the end of the guide rail 2, completing the initial snap-fit ​​positioning. At this time, the nut 10 of the limiting bracket 9 on the lower side of the rubber coating 5 is aligned with the through hole 11 on the guide rail 2. The guide rail 2 is fixed by threading the screw through the through hole 11 and the nut 10, thus forming the rear-mounted fixed window of the car door.

[0034] The rubber coating 5 is provided with a mounting bracket 3, and the guide rail 2 is provided with a metal bracket 4; by using the mounting bracket 3 and the metal bracket 4 in conjunction with fasteners, the overall assembly and fixation of the fixed window and the car door can be achieved.

[0035] This utility model solves the defects of the existing one-piece injection molding process by first molding the glass 1, the adhesive 5, and the sealing strip 6 into a body, and then assembling it with the guide rail 2. This improves the product qualification rate and production efficiency, reduces production costs, and the assembly structure is stable and adaptable to the actual use needs of car doors. It has good practicality and promotion value.
