[0029] Reference Figure 1-6This utility model discloses an outer panel for an automobile roof, comprising: a roof outer panel body 1; an opening groove 10 on the lower surface of the roof outer panel body 1; a sliding groove 11 on the inner surface of the opening groove 10; a bidirectional lead screw 12 rotatably connected to the inner surface of the sliding groove 11; a connecting frame 13 threadedly connected to the outer surface of the bidirectional lead screw 12; and a toothed clamping block 14 fixedly connected to the upper surface of the connecting frame 13. The toothed block can improve the clamping stability of a motor 15. The inner surface of the toothed clamping block 14 is provided with... Motor 15, with a drive shaft 16 fixedly connected to its output end. A second gear 17 is fixedly connected to the outer surface of the drive shaft 16, and a first bevel gear 18 is fixedly connected to the outer surface of the second gear 17. A connecting shaft 19 is rotatably connected to the inner surface of the top cover outer plate body 1, with a second bevel gear 20 fixedly connected to the outer surface of the connecting shaft 19. A disc 21 is fixedly connected to the outer surface of the connecting shaft 19. A skylight groove 2 is provided on the outer surface of the top cover outer plate body 1. The inner surface of the top cover outer plate body 1 is rotatably connected to... A lead screw 3 is connected to a skylight 4, which is threaded onto its outer surface. A synchronous pulley 5 is fixedly connected to the outer surface of the skylight 4, and a toothed belt 6 is driven onto the inner surface of the synchronous pulley 5. A rotating shaft 7 is rotatably connected to the inner surface of the outer plate 1 of the top cover, and a pulley 8 is fixedly connected to the outer surface of the rotating shaft 7. A first gear 9 is fixedly connected to the outer surface of the rotating shaft 7. Multiple insertion holes 26 are provided on the lower surface of the outer plate 1 of the top cover to facilitate the limiting and fixing of the disc 21. The outer surface of the skylight 4 is connected to the outer plate of the top cover. The main body 1 is slidably connected, which facilitates the opening and closing of the sunroof 4. There are two lead screws 3, which are symmetrically distributed. The diameter of the synchronous pulley 5 is smaller than that of the pulley 8, which can increase the tension of the toothed belt 6 and facilitate the synchronous rotation of the two lead screws 3. The first gear 9 and the second gear 17 mesh with each other. The inner surface of the slide groove 11 is adapted to the connecting frame 13 and is used to limit the movement of 13. There are two toothed clamping blocks 14, which are symmetrically distributed. The first conical tooth 18 and the second conical tooth 20 mesh with each other.

[0030] A pin 22 is slidably connected to the inner surface of the disc 21. A pull block 23 is fixedly connected to the lower end of the pin 22. A limit ring 24 is fixedly connected to the outer surface of the pin 22. A spring 25 is provided on the outer surface of the pin 22. The upper end of the spring 25 is fixedly connected to the limit ring 24, and the lower end of the spring 25 is fixedly connected to the disc 21.

[0031] Working principle: When the sunroof 4 needs to be opened or closed, simply start the motor 15, which drives the transmission shaft 16 to rotate the shaft 7 and pulley 8 under the meshing action of the second gear 17 and the first gear 9. Then, under the transmission action of the pulley 8 and the toothed belt 6, and the toothed belt 6 and the synchronous pulley 5, the two lead screws 3 are driven to rotate synchronously, thereby moving the sunroof 4 to realize the opening and closing operation. When the toothed clamping block 14 needs to be replaced, simply pull down the pull block 23 to drive the pin rod 22 out of the insertion hole 26 and compress the spring 25, thereby releasing the restriction on the disc 21. Then, the disc 21 is rotated around the connecting shaft 19, which drives the bidirectional rotation under the meshing action of the second conical tooth 20 and the first conical tooth 18. The lead screw 12 rotates, causing the two toothed clamping blocks 14 to move away from each other under the action of the connecting bracket 13, thereby releasing the restriction on the motor 15 as a whole. Then, the motor 15 can be removed directly to complete the disassembly. Then, the new motor 15 is placed between the two toothed clamping blocks 14, and the pull block 23 is rotated in the opposite direction to drive the two toothed clamping blocks 14 to move closer to each other, thereby limiting and fixing the motor 15 as a whole and re-meshing the second gear 17 with the first gear 9. Then, the pull block 23 is released, and under the action of the spring 25, the pin 22 will automatically insert into the corresponding insertion hole 26, thereby limiting the position of the toothed clamping blocks 14 and preventing the sunroof 4 from malfunctioning due to the loosening of the toothed clamping blocks 14.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
