Abstract

A swing chair includes a base, a seat, and a driving frame. The seat is disposed above the base. The driving frame is disposed between the base and the seat. The driving frame includes a first fixing base, a first shaft, a second fixing base, a second shaft, a first driving assembly, and a second driving assembly. The first fixing base is fixed to the base. The first shaft is rotatably connected to the first fixing base. The second fixing base is fixed to the seat. The second shaft is connected to the first shaft and the second fixing base is rotatably connected to the second shaft. The first driving assembly is configured to drive the first shaft to rotate with respect to the first fixing base. The second driving assembly is configured to drive the second fixing base to rotate with respect to the second shaft.

First claim

What is claimed is:

1. A swing chair, comprising:
a base;
a seat, disposed above the base; and
a driving frame, disposed between the base and the seat, wherein the driving frame comprises:
a first fixing base, fixed to the base;
a first shaft rotatably, connected to the first fixing base;
a second fixing base, fixed to the seat;
a second shaft, connected to the first shaft, and the second fixing base is rotatably connected to the second shaft;
a first driving assembly, coupled to the first shaft to drive the first shaft to rotate with respect to the first fixing base; and
a second driving assembly, coupled to the second fixing base to drive the second fixing base to rotate with respect to the second shaft,
wherein a central axis of the first shaft and a central axis of the second shaft are located on a same plane.

2. The swing chair according to claim 1 , wherein the first shaft and the second shaft are perpendicular to each other.

3. The swing chair according to claim 1 , wherein the first driving assembly comprises:
a motor, fixed to the first shaft;
a bearing, fixed to the first fixing base;
a driven member, fixed to the bearing, and the first shaft is connected to the bearing; and
a linking member, coupled to the motor and the driven member.

4. The swing chair according to claim 3 , wherein the linking member comprises a belt and the driven member comprises a pulley.

5. The swing chair according to claim 1 , wherein the first driving assembly comprises:
a motor, fixed to the base;
a bearing, fixed to the first fixing base;
a driven member, fixed to the first shaft, and the first shaft is connected to the bearing through the driven member; and
a linking member, coupled to the motor and the driven member.

6. The swing chair according to claim 5 , wherein the linking member comprises a belt and the driven member comprises a pulley.

7. The swing chair according to claim 1 , wherein the second driving assembly comprises:
a motor, fixed to the first shaft;
a driven member, fixed to the second fixing base;
a bearing, fixed to the driven member, and the driven member is connected to the second shaft through the bearing; and
a linking member, coupled to the motor and the driven member.

8. The swing chair according to claim 7 , wherein the linking member comprises a belt and the driven member comprises a pulley.

9. The swing chair according to claim 1 , further comprising a carrier fixed to the first shaft, wherein the first driving assembly comprises a first motor and the second driving assembly comprises a second motor, and the first motor and the second motor are fixed to the carrier.

10. The swing chair according to claim 9 , wherein a power output shaft of the first motor and a power output shaft of the second motor are located on a same plane.
