The inner sliding sleeve 23 of the rear lifting arm of the rear lifting assembly 2 is disposed within the rear sliding groove 42. The flexible shaft mounting assembly 5 is fixed to the upper part of the drive block 4 via the drive block insertion part 44, causing the drive block 4 to move together. The drive block 4 is disposed within the corresponding track of the slide rail 7 via the lower sliding wing 43. During lifting, the front lifting assembly 1 moves from the straight section of the front sliding groove 41 to the arc section, while the rear lifting assembly 2 moves from the rear end of the rear sliding groove 42 to the front end.

[0029] The front lifting assembly 1 includes a front lifting arm 11. The top of the front lifting arm 11 is hinged to the front end of the robotic arm 3 via a front riveting pin 15. A front riveting pin washer 16 is provided between the front riveting pin 15 and the front lifting arm 11, and a front washer 17 is provided between the front lifting arm 11 and the robotic arm 3. The front ends of the front lifting arm 11 are provided with front lifting arm outer sliding sleeves 12 that cooperate with the slide rail 7 via front lifting arm riveting pins 14, and the rear ends are provided with front lifting arm inner sliding sleeves 13 that cooperate with the front slide groove 41 via front lifting arm riveting pins 14.

[0030] The robotic arm 3 is a long strip sheet metal structure. The front end is provided with a front riveting hole 31 that is hinged to the front lifting arm 11, the middle part is provided with a rear riveting hole 32 that is hinged to the rear lifting arm 21, and the rear end is provided with a robotic arm locking connection part 33 that cooperates with the locking block assembly 6. The sunroof glass assembly is installed on the robotic arm 3. The motion mechanism composed of the front lifting assembly 1, the rear lifting assembly 2, the drive block 4 and the robotic arm 3 drives the robotic arm 3 to move, thereby completing the lifting or opening and closing of the sunroof glass.

[0031] Combination Figures 6-7 As shown, in this embodiment, the locking block assembly 6 is disposed within the slide rail 7, and the locking block assembly 6 is connected to the rear end of the robotic arm 3 to lock the robotic arm 3. When the rear end of the robotic arm 3 disengages from the locking block assembly 6, the robotic arm 3 unlocks and can perform the tilting action (i.e., the robotic arm 3 can tilt up). By setting the locking block assembly 6, the accidental tilting of the sunroof can be effectively prevented, while ensuring the accuracy of the movement position.

[0032] In this embodiment, the locking block assembly 6 includes a locking block body 61. The front end of the locking block body 61 is provided with a locking groove 62 that connects to the rear end of the robotic arm 3. The rear end of the locking block body 61 is provided with a first inner clamp 63 and a second inner clamp 64 that cooperate with the slide rail 7.

The flexible shaft coupling assembly 5 moves in the second sliding area 72, and the locking block assembly 6 moves in the third sliding area 73. A first locking groove 74 and a second locking groove 75 are provided in the rear sliding groove of the third sliding area 73. The first locking groove 74 cooperates with the first inner clamp 63, and the second locking groove 75 cooperates with the second inner clamp 64. By setting the first locking groove 74 and the second locking groove 75, the locking block assembly 6 can only move between the first locking groove 74 and the second locking groove 75. When the first inner clamp 63 slides into the first locking groove 74, the locking block body 61 is inserted and fixed to the rear end of the robotic arm 3. When the second inner clamp 64 slides into the second locking groove 75, the locking groove 62 at the front end of the locking block body 61 is disengaged from the robotic arm locking connection part 33 at the rear end of the robotic arm 3, thus completing the unlocking.

[0034] When the sunroof is raised, the motor drives the flexible shaft 8 to first drive the locking block assembly 6 to move backward, so that the mechanical arm locking connection part 33 at the rear end of the mechanical arm 3 disengages from the locking groove 62 at the front end of the locking block body 61. Then the flexible shaft 8 drives the flexible shaft hook assembly 5 to run, thereby driving the drive block 6 to run, that is, the entire mechanism assembly moves, completing the sunroof raising, opening and closing.
