In the prior art, the front sunroof body 3 is generally driven by a motor and a pull lock. The slider 7 of the rear sunroof body 4 can also be moved by a motor-driven pull lock or manually. The slider 7 is provided with a front slide groove 71 and a rear slide groove 72. The upper end of the front lift arm 5 is hinged to the sunroof bracket 4. The lower end of the front lift arm 5 has a front protrusion 51 that inserts into the front slide groove 71. The upper end of the rear lift arm 6 is hinged to the sunroof bracket 4. The lower end of the rear lift arm 6 has a rear protrusion 61 that inserts into the rear slide groove 72. The upper and lower ends of the front protrusion 51 and the rear protrusion 61 both have arc-shaped surfaces.

[0033] The slider 7 includes a front plate 73 and a rear plate 74, which are rotatably connected. The front plate 73 has a slot, and the rear plate 74 has a fixed rod 75. A limit plate 76 is fixed on the rod 75. The front slide groove 71 is located on the front plate 73, and the rear slide groove 72 is located on the rear plate 74. The front plate 73 and the rear plate 74 fit together more well to slide on the guide rail 1. When installing the front plate 73 and the rear plate 74, the rod 75 is inserted into the slot and then rotated. The limit plate 76 prevents the front plate 73 and the rear plate 74 from separating.

[0034] The guide rail 1 is provided with a stabilizing groove 11. The front plate 73 and the rear plate 74 are both fixed with sliding plugs 77 that are inserted into the stabilizing groove 11. The sliding plugs 77 are inserted into the stabilizing groove 11 so that the slider 7 can slide stably.

[0035] The front slide groove 71 includes a connected slide groove 1 711, a slide groove 2 712, and a slide groove 3 713. The slide groove 1 711 and the slide groove 3 713 are at the same height. The position of the slide groove 2 712 is higher than that of the slide groove 1 711. The front protrusion 51 is located in the slide groove 3 713. The front lifting arm 5 is fixed with a front insert block 52 that is inserted into the slide groove 2 712. The upper and lower ends of the front insert block 52 also have arc-shaped surfaces. The rear slide groove 72 includes a connected straight section 721 and an inclined section 722. The rear protrusion 61 is located in the straight section 721.

[0036] A fixing block 8 is fixed on the guide rail 1. The fixing block 8 has an entry groove 81 and a limiting groove 82. A limiting block 62 is fixed on the rear lifting arm 6. The limiting block 62 is located in the limiting groove 82. The entry groove 81 and the limiting groove 82 are connected. The limiting block 62 and the rear protrusion 61 are located on both sides of the rear lifting arm 6.

[0037] An extension block 63 is fixed on one side of the rear lifting arm 6. The guide rail 1 has a side groove 12 for sliding the extension block 63. The extension block 63 is located in the side groove 12. The rear protrusion 61, located in the straight section 721, cooperates with the extension block 63 to keep the rear lifting arm 6 stable.

[0038] In use, slider 7 slides backward within guide rail 1, front protrusion 51 slides within slide groove 3 713, rear protrusion 61 slides within straight section 721, and front insert block 52 slides within slide groove 2 712. As the front insert block 52 slides from slide groove 2 712 into slide groove 1 711, front protrusion 51 simultaneously enters slide groove 2 712. The front end of sunroof bracket 4 rotates downward with the hinge point between rear lifting arm 6 and sunroof bracket 4 as the center. Sunroof bracket 4 moves together with rear sunroof body 2. Then, front plate 73 and rear plate 74 continue to move backward, rear protrusion 61 enters inclined section 722, and rear lifting arm 6 extends with extension block 6. Rotating around the center of the circle causes the rear side of the sunroof bracket 4 to descend. The sunroof bracket 4 moves together with the rear sunroof body 2. As the rear lifting arm 6 rotates downward, the limiting block 62 moves from the limiting groove 82 into the entry groove 81. At this time, the rear sunroof body 2 completes the overall descent. The slider 7 moves the sunroof bracket 4 backward through the front lifting arm 5 and the rear lifting arm 6. The extension block 63 and the limiting block 62 slide together in the side groove 12. The sunroof bracket 4 moves backward with the rear sunroof body 2. The limiting block 62 moves out of the entry groove 81. The rearward movement of the rear sunroof body 2 makes the sunroof open wider, providing better space and visibility.

[0039] When the rear sunroof body 2 returns to its original position, the slider 7 moves the sunroof bracket 4 forward via the front and rear lifting arms 6. The sunroof bracket 4 moves the rear sunroof body 2 forward, and the limiting block 62 moves into the entry groove 81 and is then blocked. The slider 7 continues to move forward, and the rear protrusion 61 returns from the inclined section 722 to the straight section 721. The rear lifting arm 6 rotates upward around the extension block 63, and the limiting block 62 enters the limiting groove 82, preventing the rear sunroof body 2 from moving forward or backward. During the process of the rear protrusion 61 returning from the inclined section 722 to the straight section 721, the front insert block 52 slides forward. The front protrusion 51 moves from the groove 1 711 towards the groove 2 712, and the front protrusion 51 moves from the groove 2 712 towards the groove 3 713. Then the slider 7 continues to move forward, and the rear protrusion 61 moves within the straight section 721. The front insert 52 moves from the groove 1 711 to the groove 2 712, and the front protrusion 51 moves from the groove 2 712 to the groove 3 713. During the process of the front insert 52 moving from the groove 1 711 to the groove 2 712, the front end of the window bracket is restored by the front lifting arm 5, which in turn restores the rear sunroof body 2. At this time, the rear sunroof body 2 is restored.
