[0019] This utility model provides a gear chain folding structure for an automobile table, including a table 1 and a folding assembly. The folding assembly includes two folding parts 2, a driving gear 3, a chain 5, and a driven gear 6. Each folding part 2 includes a mounting bracket 7, a first pin 8, a first folding rod 9, a second pin 10, a second folding rod 11, and a guide member 14. The guide member 14 includes an eccentric shaft 15, a guide shaft 16, a guide wheel 17, and a guide rod 18. The aforementioned solution enables the automobile table 1 to fold, reducing the space occupied in the vehicle and improving passenger comfort.

[0020] In this specific embodiment, the two folding sections 2 are respectively located on the tabletop 1. Each folding section 2 includes a mounting frame 7, a first pin 8, a first folding rod 9, a second pin 10, and a second folding rod 11. The mounting frame 7 is fixedly connected to the tabletop 1 and is located on the side of the tabletop 1. The first pin 8 is rotatably mounted on the mounting frame 7. One end of the first folding rod 9 is fixedly connected to the first pin 8, and the end of the first folding rod 9 away from the first pin 8 has a first pin hole 12. The second pin 10 is rotatably mounted on the mounting frame 7. One end of the second folding rod 11 is fixedly connected to the second pin 10, and the end of the second folding rod 11 away from the second pin 10 has a second pin hole 13. The driving gear 3 is fixedly connected to the second pin 10 and is located on the side of the second pin 10. The chain 5 is sleeved on the side of the driving gear 3. The driven gear 6 is located inside the chain 5. The first pin hole 12 is used to connect with a rotating shaft, which hinges the first folding rod 9 to the car seat frame. The second pin hole 13 is also used to connect with a rotating shaft, which hinges the second folding rod 11 to the car seat frame. By flipping the table 1, the first folding rod 9 rotates around the first pin 8, and the second folding rod 11 rotates around the second pin 10, allowing the table 1 to open or close for passengers to place items. Alternatively, a drive motor can be installed inside the table 1 to drive the driven gear 6 to rotate. The driven gear 6 drives the driving gear 3 to rotate via the chain 5, and the driving gear 3 drives the second pin 10 and the second folding rod 11 to rotate. This method also enables the table 1 to be opened and closed. This invention can achieve the folding of the table 1 with fewer parts, reducing the space occupied in the vehicle and improving passenger comfort.

[0021] The folding section 2 further includes a guide member 14, which is disposed on the side of the mounting bracket 7. The guide member 14 is used to provide guidance when the second folding rod 11 rotates.

[0022] Secondly, the eccentric shaft 15 is fixedly connected to the center of the driven gear 6; the guide shaft 16 is rotatably mounted on the mounting bracket 7; the guide wheel 17 is fixedly connected between the eccentric shaft 15 and the guide shaft 16; the guide rod 18 is hinged to the second folding rod 11 and is located on the side of the second folding rod 11. The eccentric shaft 15 is located at the eccentric position of the guide wheel 17. When the second folding rod 11 rotates, it will drive the guide rod 18 to rotate. At the same time, the driven gear 6 drives the guide wheel 17 to rotate through the eccentric shaft 15. The guide wheel 17 will always be in contact with the guide rod 18 when rotating, further optimizing the smoothness and angle control of the tabletop 1 flipping.

[0023] Meanwhile, the second folding rod 11 has an arc-shaped surface 19, which is located on the side of the second folding rod 11 closer to the guide rod 18. The arc-shaped surface 19 prevents interference with the rotation of the guide rod 18.

[0024] In using this utility model, the first pin hole 12 is used to connect with a rotating shaft, which is used to hinge the first folding rod 9 to the car seat frame. Similarly, the second pin hole 13 is used to connect with a rotating shaft, which is used to hinge the second folding rod 11 to the car seat frame. When the passenger flips the table 1, the first folding rod 9 rotates about the first pin 8, and the second folding rod 11 rotates about the second pin 10, allowing the table 1 to open or fold up for the passenger to place items. Alternatively, it is possible to install [something] inside the table 1. A drive motor drives the driven gear 6 to rotate, and the driven gear 6 drives the drive gear 3 to rotate via the chain 5. The drive gear 3 drives the second pin shaft 10 and the second folding rod 11 to rotate. In this way, the table 1 can also be folded up and down. Through the transmission of the drive gear 3, the driven gear 6, and the chain 5, the table 1 can be folded up to a designated position while flipping, reducing interference with other parts in the vehicle. This utility model can achieve the folding of the table 1 with fewer parts, reducing the space occupied in the vehicle and improving passenger comfort.
