[0037] Please refer to Figures 1 to 8 A multifunctional balancing chair includes a supporting part 10, a seat part 20, a kneeling pad part 30, a connecting mechanism 31, a supporting mechanism and a transmission mechanism 51.

[0038] The support part 10 is provided with a chair leg 12, and in the specific structure: the support part 10 includes a fixed seat fixed on the chair leg, a support seat 13 that can be swung and connected to the chair leg, and an elastic body that is connected between the fixed seat and the support seat 13, so that the support seat 13 can swing relative to the chair leg, and the elastic body is used to make the swing slow and have a rebound effect, so as to achieve an effect similar to a rocking chair, and the chair has a rocking effect regardless of whether it is a seat state or a balance chair state. According to needs, the fixed seat and the elastic body can be omitted, and the support seat 13 is directly fixed to the chair leg, and in this case, it does not have a rocking effect.

[0039] The seat portion 20 is rotatably connected to the support seat 13 and the angle between the seat portion 20 and the horizontal plane can be controlled through the relative movement of the seat portion 20. According to needs, a mechanism can be set so that when the seat portion 20 tilts forward by an angle of 30" to 40", the locking is completed, that is, the maximum swing angle of the seat portion is limited. The kneeling pad portion 30 is rotatably connected to the seat portion 20 and is connected to the support seat 13 through a connecting mechanism 31. The kneeling pad portion 30 can move between a first position aligned with the seat portion 20 and a second position constituting a kneeling pad of a balancing chair. The swing of the seat portion 20 and the movement of the kneeling pad portion 30 are linked so that the inclination angles of the kneeling pad portion 30 and the seat portion 20 change synchronously in opposite directions. Among them, when in the first position, the multifunctional balancing chair constitutes a seat state, such as Figure 1 , 2 , 4, and 7, when the multifunctional balance chair is in the second position, it forms a balance chair state, such as Figure 3 , 5 , as shown in Figure 8.

[0040] The support mechanism is movably connected to the support seat 13 and can move between a support position and a non-support position relative to the support seat 13. When the multifunctional balancing chair is in a seat state, the support mechanism is in the support position, and when it is in a seat state, the support mechanism is in the non-support position, that is, the support mechanism in the support position is connected to the kneeling pad part 30 to support the kneeling pad part 30 in the first position, so that the multifunctional balancing chair remains in the seat state; the movement of the support mechanism, the swing of the seat part 20 and the movement of the kneeling pad part 30 are linked to improve the convenience and stability and reliability of the multifunctional balancing chair in changing between the two states.

[0041] The support mechanism includes a support member 52, which can be rotatably connected to the support seat 13.

[0043] In the specific structure: the support member 52 is in a V-shaped structure and has a common end 521 and two end portions 522, 522', the common end 521 is rotatably connected to the support seat 13, one end portion 522 constitutes a support portion that can support the kneeling pad part 30, and the other end portion 522' is rotatably connected to the second connecting rod 511; the back side of the kneeling pad part 30 is fixed with a supporting portion 32, and the supporting portion 32 of the kneeling pad part 30 located in the first position has a slanted supporting surface 321 that is inclined downward, and the slanted supporting surface 321 is adapted to support the support portion of the support member 52 located in the supporting position. In this embodiment, the support is stable and reliable, and the second connecting rod is driven to move by the first connecting rod, and the support member is driven to rotate by the movement of the second connecting rod. In addition, the support member 52 is in a V-shaped structure, which can stably and reliably realize transmission and avoid the support member interfering with the change of the multifunctional balance chair. Furthermore, the rotation axis of the support member 52 relative to the support seat 13 and the swing axis of the seat portion 20 relative to the support seat 13 coincide with each other, and the structure is more compact, which can stably and reliably realize transmission and avoid the support member interfering with the change of the multifunctional balance chair. Furthermore, the middle part of the first connecting rod 311 is concavely provided with a through hole, one end of the second connecting rod 511 is located in the through hole, and a pivot is provided to connect the first connecting rod and the second connecting rod; the terminal part 522 of the support member 52 is provided with a groove, the terminal end of the second connecting rod 511 is located in the groove, and a pivot is provided to connect the second connecting rod and the support member.
