[0026] Example 1

[0027] like Figure 1As shown, this utility model proposes a folding shaft structure, including a base 1 and a shaft mechanism disposed on both sides of the outer wall of the base 1. The base 1 serves as the basic support component of the entire structure, providing a platform for the installation and fixation of other components, ensuring the stability of the entire shaft structure during operation. The shaft mechanism includes multiple limiting rotating rings 2 fixed to both sides of the outer wall of the base 1. The limiting rotating rings 2 precisely limit the rotation range of the bearing rings 3, ensuring the accuracy of their rotation trajectory and preventing deviation or shaking during rotation, which would affect the stability of the entire folding operation. The inner walls of the multiple limiting rotating rings 2 are rotatably connected to the bearing rings 3. The bearing rings 3 can rotate flexibly under the constraint of the limiting rotating rings 2, driving other connected components to perform corresponding movements. Multiple connecting plates 4 are fixedly connected to the outer walls of the two bearing rings 3. A through rod 5 passes through one side of the outer wall of each of the multiple connecting plates 4. External fixing plates 6 are sleeved at both ends of the two through rods 5. The multiple external fixing plates 6 are located on one side of the gear reduction mechanism. The through rods 5 are connected to the connecting plates 4. Driven by the movement, it moves and its movement directly participates in the folding or unfolding action, achieving a change in the shape of the entire structure through changes in its own position.

[0028] In addition, such as Figure 2 As shown, a gear reduction mechanism is provided at the bottom of the base 1. The gear reduction mechanism includes an extension plate 7 fixed to the bottom of the base 1. Reduction gears 8 are rotatably connected to both sides of the outer wall of the extension plate 7. Limiting rods 9 are fixedly connected to both ends of the two bearing rings 3. Driving gears 10 are fixedly connected to the outer walls of multiple limiting rods 9. Multiple driving gears 10 are meshed with reduction gears 8. The extension plate 7 mainly serves to support and position the reduction gears 8, ensuring that the reduction gears 8 can rotate stably. The meshing of the reduction gears 8 with the driving gears 10 can reduce the rotational speed transmitted by the driving gears 10, so that the speed of the folding process can be effectively controlled, avoiding structural damage or unstable operation due to excessive speed, and making the folding operation more stable and safe.

[0029] And, as Figure 3 and Figure 4As shown, a buffer mechanism is provided at the top of the base 1. The buffer mechanism includes a bottom connecting block 11 fixed to the top of the base 1. A connecting spring 12 is fixedly connected to the top of the bottom connecting block 11. A top connecting block 13 is fixedly connected to the end of the connecting spring 12 away from the bottom connecting block 11. A support plate 14 is fixedly connected to the top of the top connecting block 13. Connecting sections 15 are fixedly connected to both sides of the outer wall of the support plate 14. Connecting arms 16 are rotatably connected to the outer walls of the two connecting sections 15. Telescopic rods 17 are rotatably connected to the ends of the multiple connecting arms 16 away from the connecting sections 15. Fixed sections 18 are rotatably connected to the ends of the two telescopic rods 17 away from the connecting arms 16. One end of each of the two fixed sections 18 is fixedly connected to one side of the connecting plate 4 near the middle. The bottom connecting block 11, as the connecting component between the buffer mechanism and the base 1, is responsible for transmitting the force of the buffer mechanism to the base 1. It also provides a fixed base for the connecting spring 12. This design allows the device to absorb and buffer energy during folding when subjected to external impact through compression and expansion, reducing damage to the structure caused by collisions or rapid movements and protecting the entire rotating shaft structure and connected equipment. The top connecting block 13 receives the buffering force transmitted by the connecting spring 12 and provides an installation platform for the support plate 14, transferring the buffered force to the support plate 14. The support plate 14 is mainly used to support items placed on the rotating shaft structure. The connecting section 15 and the connecting arm 16 form a rotatable connection structure, which can change the angle according to the folding action, thus adjusting the position of the support plate 14. The telescopic rod 17 can extend and retract under the drive of the connecting arm 16 to adapt to different folding states. The fixed section 18 connects the telescopic rod 17 to the connecting plate 4, enabling the entire buffering mechanism and the rotating shaft mechanism to work together. During folding, the various components cooperate to effectively buffer and disperse external forces, ensuring smooth folding operations.

[0030] In this embodiment, when a folding operation is required, the rotating bearing ring 3 can rotate stably due to the limiting effect of the limiting rotating ring 2. The rotation of the bearing ring 3 drives the connecting plate 4 to move, which in turn drives the through rod 5 to move. At the same time, the limiting rods 9 at both ends of the two bearing rings 3 also rotate. The driving gear 10 fixedly connected to the limiting rod 9 meshes with the reduction gear 8, thereby achieving deceleration rotation, making the folding process more stable and controllable. The driving gear 10 transmits the rotation of the bearing ring 3 to the reduction gear 8. The reduction gear 8 uses its own gear ratio to reduce the rotation speed. During the folding process, the top connecting block 13 is connected to the bottom connecting block 11 through the connecting spring 12, which plays a buffering role. The support plate 14 is mainly used to support the items placed on the rotating shaft structure. The connecting section 15 and the connecting arm 16 form a rotatable connecting structure, which can change the angle according to the needs of the folding action to realize the position adjustment of the support plate 14. The telescopic rod 17 can extend and retract under the drive of the connecting arm 16 to adapt to different folding states. The fixed section 18 connects the telescopic rod 17 to the connecting plate 4, so that the entire buffer mechanism and the rotating shaft mechanism can work together.

[0031] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
