[0052] The two ends of the front crossbeam 40 of the sunroof are connected to the sunroof guide rails 10 on both sides, and the middle part of the front crossbeam 40 of the sunroof is connected to the rear crossbeam of the car body by bolts, thereby fixing the sunroof of the car body to the car body.

[0053] Figure 10 yes Figure 1 A magnified view of part D in the middle.

[0054] like Figure 10As shown, the sunroof guide rail 10 is provided with a first flexible shaft groove 15, and the sunroof front crossbeam 40 is provided with a second flexible shaft groove 41 that matches the first flexible shaft groove 15. The flexible shaft passes through the first flexible shaft groove 15 and the second flexible shaft groove 41. One end of the flexible shaft extending from the first flexible shaft groove 16 is connected to the first connecting rod 311, and the other end extending from the second flexible shaft groove 41 is connected to the motor shaft of the motor. The motor (not shown in the figure) is mounted on the sunroof front crossbeam 40. By driving one end of the flexible shaft to rotate, the other end of the flexible shaft is extended and retracted, allowing the first connecting rod 311 to slide within the drive groove 11. Through the driving method of the motor and the flexible shaft, the sliding protrusion 3111 can slide more smoothly, further improving the quality of the product.
