Example 1

Referring to fig. 1 to 5, the present embodiment provides a swivel assembly for furniture, the furniture including a fixed base and a swivel unit disposed above the fixed base, the swivel assembly including a swivel member 10, a fixed member 20 and a driving mechanism 30;

the rotating part 10 is relatively and rotatably connected with the fixed part 20, and a rotating shaft through hole 11 is formed in the rotating part 10;

the driving mechanism 30 comprises a driving shell 31 and a driving shaft 32 which rotate relatively, and the driving shell 31 is fixedly connected with the rotating part 10;

the fixed part 20 is arranged on one side of the rotating part 10 far away from the driving mechanism 30, the fixed part 20 is provided with a gear ring 21, one end of the driving shaft 32 passes through the rotating shaft through hole 11 and is connected with a driving gear 40, and the driving gear 40 is meshed with the gear ring 21;

the rotation member 10 is used to connect with a rotation unit, the fixing member 20 is used to connect with a fixed base, and the driving mechanism 30 is used to drive the rotation member 10 to rotate relative to the fixing member 20.

The driving mechanism 30 is disposed on a side of the rotation member 10 away from the fixed base. Since the driving mechanism 30 is installed on the side of the rotation member 10 close to the furniture rotation unit in the embodiment of the present specification, the driving mechanism 30 can be supported by the rotation member 10, and the driving housing 31 and its internal components and the driving shaft 32 do not need to be affected by a load in the vertical direction. On the contrary, if the driving mechanism 30 is disposed on one side of the rotating member 10 close to the fixed base, and the driving shaft 32 passes through the rotating shaft through hole 11 to engage with the fixed member 20 and drive the rotating member 10 to rotate, the driving mechanism 30 not only bears its own weight in the vertical direction, but also is affected by the loads of the rotating member 10 and the fixed member 20, which seriously affects the service life of the driving mechanism 30.

As shown in fig. 4, the outer side wall of the driving gear 40 is provided with a gear 41 matching the gear ring 21, and the gear 41 is engaged with the gear ring 21. In the embodiment of the present specification, the fixing member 20 is used for connecting a fixing base of furniture, the fixing member 20 is in a relatively stationary state, and the driving shaft 32 is connected with the driving housing 31 and can rotate relatively. In actual use, the driving shaft 32 of the driving mechanism 30 rotates and engages with the gear ring 21 on the fixed member 20, that is, the driving shaft 32 revolves along the gear ring 21 while rotating on itself; the driving shell 31 revolves along the gear ring 21 under the driving of the driving shaft 32; the rotation member 10 fixedly coupled to the driving housing 31 rotates along the gear ring 21; the effect is that the rotary member 10 drives the rotary unit in the furniture to rotate relatively to the fixed base. Since the driving housing 31 and the rotating member 10 connected thereto only rotate along the gear ring 21, that is, the driving housing 31 and the rotating member 10 only perform revolution motion and do not rotate, the wires on the driving mechanism 30 only swing and do not twist, thereby reducing or even eliminating the interference of the wire winding on the furniture rotation.

Preferably, the distance from the rotation shaft through hole 11 to the center of the rotation member 10 is equal to the distance from the gear ring 21 to the center of the fixing member 20.
