[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] It should be noted that when a component is referred to as being "mounted on", "fixed on" or "disposed on" another component, it may be directly on the other component or there may be a central component at the same time. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time.

[0033] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, the utility model provides a flip connection component, including a connecting frame 11, a rotating main part 12, a rotating auxiliary part 13 and a flip arm 14, wherein the rotating main part 12 is fixedly connected to the connecting frame 11, and the flip arm 14 is fixedly connected to the rotating auxiliary part 13, wherein the rotating main part 12 and the rotating auxiliary part 13 are relatively rotatably connected, wherein the rotating main part 12 and the rotating auxiliary part 13 have the same rotation center, and the rotating auxiliary part 13 has an internal gear 15, wherein a main gear 16 is arranged inside the internal gear 15, wherein the main gear 16 rotates inside the internal gear 15, wherein the main gear 16 is eccentrically arranged at the rotation center, wherein the main gear 16 is partially meshed with the internal gear 15, and drives the main gear 16 to rotate eccentrically, wherein the main gear 16 drives the internal gear 15 to rotate, thereby the rotating auxiliary part 13 rotates, and drives the flip arm 14 to flip relative to the connecting frame 11. The utility model has a small size and low noise, and can be applied to the rotatable connection of furniture modules such as seat headrests, table boards, and headrests. The utility model drives the internal gear 15 to rotate through the eccentrically rotating main gear 16. When the connecting frame 11 is connected and fixed, the external driving shaft drives the main gear 16 to rotate eccentrically, and the main gear 16 is partially meshed with the internal gear 15. The number of teeth of the main gear 16 is less than the number of teeth of the internal gear 15. It can not only achieve a deceleration effect, but also have a larger transmission ratio. Only a smaller motive force is needed to enable the rotating secondary part 13 to obtain a larger rotation output force. Conversely, when the main gear 16 loses the input of the motive force, it has a larger resistance when it wants to rotate the rotating secondary part 13 or flip the flip arm 14. That is to say, it has a certain self-locking effect. When the main gear 16 is driven to drive the rotating secondary part 13 to rotate to the corresponding angle, after no longer driving, at this angle, the rotating secondary part 13 can still be maintained at this angle and has sufficient bearing capacity. Therefore, the utility model can realize the angle adjustment between the flip arm 14 and the connecting frame 11, and can keep the angles of the two fixed at any angle after adjustment.

[0035] Further, the utility model provides a flip connection component, the rotating main part 12 is provided with a rotating sleeve 17 at the rotation center, the rotating main part 12, the rotating auxiliary part 13 and the main gear 16 are all installed on the rotating sleeve 17, and the rotating sleeve 17 rotates to drive the main gear 16 to rotate eccentrically. The external drive shaft can be installed in the sleeve to drive the rotating sleeve 17, and the rotating sleeve 17 rotates, only driving the main gear 16 to rotate eccentrically, and rotating relative to the rotating main part 12 and the rotating auxiliary part 13. Further, the utility model provides a flip connection component, the middle part of the rotating sleeve 17 is provided with a drive shaft hole 18, which is used to connect with the external drive shaft, so as to facilitate the automatic angle adjustment of the utility model. Further, the utility model provides a flip connection component, the drive shaft hole 18 is a non-circular shaft hole or a shaft hole with a keyway. Further, the utility model provides a flip connection component, the drive shaft hole 18 is a hexagonal shaft hole.

[0036] Furthermore, in the flip connection component provided by the utility model, an eccentric shaft portion 19 is provided on the rotating sleeve 17, the axis of the eccentric shaft portion 19 is eccentrically arranged with the axis of the rotating sleeve 17, the main gear 16 is mounted on the eccentric shaft portion 19, and the main gear 16 rotates on the eccentric shaft portion 19. The eccentric shaft portion 19 is also a circular shaft, the rotating auxiliary portion 13, the rotating main portion 12 and the rotating sleeve 17 have the same rotation center (axis), the axis of the eccentric shaft portion 19 deviates from the rotation center, and when the eccentric shaft portion 19 drives the main gear 16 to operate, its axis rotates around the rotation center (axis of the rotating sleeve 17).

[0037] Furthermore, in the flip connection component provided by the utility model, the rotating main part 12 is a rotating inner wheel, the rotating auxiliary part 13 is a rotating outer wheel, the rotating outer wheel is mounted on the rotating inner wheel, the rotating inner wheel rotates on the rotating shaft sleeve 17, and the rotating outer wheel rotates on the rotating inner wheel. The rotating shaft sleeve 17 is the rotating shaft of the rotating inner wheel, and the rotating inner wheel is equivalent to the rotating shaft of the rotating outer wheel, which can ensure the stable operation of the structure and is conducive to maintaining low noise.

[0038] Furthermore, in the flip connection component provided by the utility model, the main gear 16 is installed between the rotating inner wheel and the connecting frame 11, and the connecting frame 11 is fixedly connected to the rotating inner wheel. Furthermore, both ends of the rotating sleeve 17 pass through the rotating auxiliary part 13, the rotating main part 12, the connection between the connecting frame 11 and the rotating main part 12, and the connection between the rotating arm and the rotating auxiliary part 13, and are exposed to the outside world, so that both ends can be connected to the external drive shaft.

[0039] Furthermore, the flip connection component provided by the utility model has a plurality of connection posts 20 disposed between the rotating inner wheel and the connection frame 11, and the connection frame 11 is fixedly connected to the rotating inner wheel through the connection posts 20. In this embodiment, there are four connection posts 20, and the connection frame 11 is fixedly connected to the connection posts 20 by screws. Further, the flip connection component provided by the utility model has the connection posts 20 disposed through the main gear 16, the connection posts 20 are symmetrically disposed around the center of rotation, the main gear 16 is provided with a plurality of limiting holes 21 corresponding to the connection posts 20 one by one, the connection posts 20 are fixedly connected to the connection frame 11 through the limiting holes 21, the connection posts 20 are cylindrical, the limiting holes 21 are circular holes, and the aperture of the limiting holes 21 is larger than the diameter of the connection posts 20 located in the limiting holes 21. The movable path of the limiting hole 21 is similar to the eccentric shaft 19 of the rotating sleeve 17. Therefore, there needs to be enough movable space inside the limiting hole 21 to facilitate the eccentric rotation of the main gear 16. The connecting column 20 cooperates with the limiting hole 21 to limit the movable range of the main gear 16 to ensure normal force on the tooth.

[0040] In summary, the utility model has a small size and low noise, and can be applied to the rotatable connection of furniture modules such as seat headrests, table boards, and headrests. The utility model drives the internal gear to rotate through the eccentrically rotating main gear. When the connecting frame is connected and fixed, the external driving shaft drives the main gear to rotate eccentrically, and the main gear is partially meshed with the internal gear. The number of teeth of the main gear is less than the number of teeth of the internal gear. It can not only achieve a deceleration effect, but also have a larger transmission ratio. Only a smaller original power is needed to make the rotating secondary part obtain a larger rotation output force. Conversely, when the main gear loses the input of the original power, it has a larger resistance to make the rotating secondary part rotate, or the flip arm flip. That is to say, it has a certain self-locking effect. When the main gear is driven to drive the rotating secondary part to rotate to the corresponding angle, after no longer driving, at this angle, the rotating secondary part can still be maintained at this angle and has sufficient bearing capacity. Therefore, the utility model can realize the angle adjustment between the flip arm and the connecting frame, and can keep the angles of the two fixed at any angle after adjustment.
