[0028] like Figure 1-8 The illustrated rear door corner window guide rail assembly includes a triangular outer frame 1. A movable arm 3 is movably mounted on the inner wall of the triangular outer frame 1. A guide rail 6 is movably mounted on the end of the movable arm 3 away from the triangular outer frame 1. Two first positioning grooves 7 are formed on the upper surface of the guide rail 6. Two first positioning pins 8 are fixedly connected to the lower surface of the triangular outer frame 1. The first positioning pins 8 are located inside the first positioning grooves 7. Two first screws 9 are threadedly connected to the side wall of the guide rail 6. The first positioning pins 8 and the guide rail 6 are connected by the first screws 9. The lower surface of the triangular outer frame 1 has two second positioning grooves 10. A second positioning pin 11 is fixedly connected to the upper surface of the guide rail 6, located inside the second positioning groove 10. Two second screws 12 are threaded onto the side wall of the triangular outer frame 1. The second positioning pin 11 and the triangular outer frame 1 are threaded together by the second screws 12. A corner window assembly 13 is movably installed inside the guide rail 6. When the rear door corner window guide rail assembly needs to be disassembled, the first screw 9 and the second screw 12 are turned off to remove them, and then the guide rail is slowly lowered. Rail 6 detaches the guide rail 6 from the triangular outer frame 1. Ensure the guide rail 6 remains horizontal. As the guide rail 6 continues to descend, it will cause the moving arm 3 to descend as well, stopping when the moving arm 3 can no longer descend. At this point, the corner window assembly 13 is still on the guide rail 6, but it is completely detached from the triangular outer frame 1. The corner window assembly 13 can then be easily removed. The guide rail assembly is now completely separated, allowing replacement of damaged parts. The inner wall of the triangular outer frame 1 has two first limiting grooves 2. The side wall of the moving arm 3 is fixedly connected to two first limiting pins 4. There are two limit pins. The first limit pin 4 is located inside the first limit groove 2 and can slide in the first limit groove 2. At the same time, the movable arm 3 is used to connect the triangular outer frame 1 and the guide rail 6 together for easy subsequent installation. The inner wall of the guide rail 6 is provided with a rotating groove 19. There are two rotating grooves 19. The side wall of the movable arm 3 is fixedly connected with a rotating pin 5. There are two rotating pins 5. The rotating pin 5 is located below the first limit pin 4 and inside the rotating groove 19. The rotating pin 5 can rotate in the rotating groove 19 and can adjust the tilt angle between the guide rail 6 and the movable arm 3.

[0029] The upper surface of the guide rail 6 is provided with a second limiting groove 15. The cross-sectional shape of the second limiting groove 15 is an isosceles trapezoid. The side wall of the corner window assembly 13 is fixedly connected with a second limiting pin 14. There are two second limiting pins 14. The second limiting pins 14 are located inside the second limiting groove 15. The second limiting pins 14 allow the corner window assembly 13 to slide in the second limiting groove 15, which is convenient for removing and placing the corner window assembly 13. At the same time, it also makes it difficult for the corner window assembly 13 to fall off. The inner wall of the triangular outer frame 1 is provided with a sealing groove 16. The inner surface of the sealing groove 16 is fixedly connected with a sealing strip 17. The sealing groove 16 and the sealing strip 17 cooperate with each other to increase the sealing between the triangular outer frame 1 and the corner window assembly 13. The side wall of the guide rail 6 is provided with a drainage groove 18. Rainwater will slide down the surface of the corner window assembly 13 and eventually flow out through the drainage groove 18.

[0030] Working principle: When it is necessary to disassemble the rear door corner window guide rail assembly, loosen the first screw 9 and the second screw 12 to remove them. Then slowly lower the guide rail 6 so that the guide rail 6 is separated from the triangular outer frame 1. Note that the guide rail 6 should be kept horizontal. As the guide rail 6 continues to descend, it will drive the moving arm 3 to descend as well until the moving arm 3 can no longer descend and stops moving. At this time, the corner window assembly 13 is still on the guide rail 6, but the corner window assembly 13 is completely separated from the triangular outer frame 1. At this time, the corner window assembly 13 can be easily removed. Thus, the guide rail assembly is completely separated and the damaged parts can be replaced.
