[0015] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0016] Refer to Figure 2 、 Figure 4, a car sunroof drive assembly with a lifting slide, comprising a support arm 1, a front connecting rod 36, a main slider 37, and a rear connecting rod 38, wherein a track main slider is arranged at the bottom of the front connecting rod 36, and the track main slider moves along the corresponding slide groove of the sunroof track; a rear slide groove 43 is opened on the main slider 37, and a rear slide rod 17, a rear slide rod 29 and a rear slide rod 30 are arranged on the rear connecting rod 38, wherein the rear slide rod 17 and the rear slide rod 29 are respectively located on both sides of the rear connecting rod 38, and the rear slide rod 17 and the rear slide rod 30 are located on the same side of the rear connecting rod 38, and the main slider 37 and the track main slider 361 are both located on the side away from the support arm 1; a lifting slide groove 4 is arranged in the sunroof track, and a first arc slide is arranged on the lifting slide groove 4, and the track main slider 361 enters or exits the bottom surface of the sunroof track from the first track slider area through the first arc slide. The mechanism structure of the present invention is greatly simplified. A lifting slide groove is installed in the sunroof track. The lifting slide groove does not need to follow the movement of the moving structural parts. The sunroof drive assembly no longer needs a locking slider to follow the movement to guide the movement of the front connecting rod when the sunroof is initially opened and closed. The mechanism of the present invention is simplified from 5 moving structural parts (i.e., 3 connecting rod parts and 2 slider parts) of the traditional mechanism to 4 parts (i.e., 3 connecting rod parts and 1 slider part), the reliability is improved, and the probability of mechanical problems is greatly reduced. During the deployment of the mechanism, the glass cover can be lifted up slowly and at a uniform speed instead of with a large speed fluctuation, and the risk of abnormal noise of the mechanism and abnormal noise caused by friction of the sunroof sealing strip is greatly reduced.

[0017] The sunroof track is also provided with a locking slide groove 3, on which a second arc-shaped slide is provided, and the first rear slide bar 17 passes through the second arc-shaped slide and enters or exits the top surface of the sunroof track from the third track slider area. The present invention guides the movement of the rear connecting rod in the initial opening and closing of the sunroof by embedding the locking slide groove in the sunroof track without following the movement of the moving structure.

[0018] Track sliders are arranged at both ends of the main slider 37, and both track sliders are located in the second track slider area; a driving block 2 is also arranged in the second track slider area, and a claw protruding from the side of the driving block 2 is arranged on the driving block 2, and the claw corresponds to the driving connection hole of the main slider 37 and is plugged and connected; the driving block 2 corresponds to the first driving block and the second driving block respectively, wherein the first driving block is located between the two track sliders; the first driving block and the second driving block are linked. The driving block of the present invention is fixedly connected with a transmission member, and is connected to the driving mechanism of the automobile sunroof through the transmission member, and the first driving block is connected to the main slider through the claw to control the movement of the main slider.

[0019] Reference Figure 2 , Figure 6, the support arm 1 is used to support and connect the skylight cover plate, and the front hinge hole and the rear hinge hole are respectively arranged at both ends thereof. The front end of the front link 36 is provided with a first riveting pin and is connected to the front hinge hole through the first riveting pin, so as to realize the hinge connection between the front link 36 and the support arm 1. The rear end of the rear link 38 is provided with a second riveting pin and is connected to the rear hinge hole through the second riveting pin, so as to realize the hinge connection between the rear link 38 and the support arm 1. A front slide bar 363 is further arranged on the front link 36. The front slide bar 363 is a horizontally placed 7-shaped structure, and the vertical bar of the 7-shaped structure is arranged towards the support arm 1. The front slide bar 363 and the third rear slide bar 30 are both located in the third track slider area, and the front slide bar 363 and the third rear slide bar 30 both move along the corresponding sliding grooves in the third track slider area. The contact end of the vertical bar of the 7-shaped structure with the corresponding sliding groove in the third track slider area and the contact end of the third rear slide bar 30 with the corresponding sliding groove in the third track slider area are both arc-shaped surfaces; the second rear slide bar 29 is arranged corresponding to the rear sliding groove 43, and the first rear slide bar 17 and the third rear slide bar 30 are both located on the side of the rear link 38 facing the support arm 1. After the mechanism of the present invention is unfolded, since both the front link and the rear link have two sliding feet sliding within the guide rails, and at the same time, both the front link and the rear link are rotationally hinged to the support arm, the heights of the front and rear ends of the support arm relative to the guide rails are both stable, ensuring the best morphological stability of the unfolded mechanism; only one sliding pair (the cooperation between the second rear slide bar 29 and the rear sliding groove 43) between the main slider and the rear link can drive the mechanical group to complete the action, which not only has a simple and reliable action principle but also ensures the smoothness of the mechanism unfolding process.

[0020] Refer to Figure 3 , an arc-shaped elastic piece 371 is arranged on the top surface of any one of the track sliders, wherein the outer arc surface of the arc-shaped elastic piece 371 is arranged upward, and an M-shaped through hole is arranged in the middle of the arc-shaped elastic piece 371. The M-shaped through hole in the middle of the arc-shaped elastic piece of the present invention forms an "arch" - shaped elastic piece feature, so that the main slider slides more stably and reliably in the guide rail, and the structure is simple.

[0021] Refer to Figure 2 , Figure 5 , a convex block 362 is arranged on the side of the track main slider 361 facing the front slide bar 363, and a groove is arranged on the side of the second driving block facing the track main slider 361. The convex block 362 can be matched with the groove. The present invention limits the front link when the skylight is closed by the cooperation between the convex block on the side of the track main slider facing the front slide bar and the groove of the second driving block.

[0022] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
