Technical Field

[0001] The utility model relates to a motor-driven adjustable chair, belonging to the technical field of office or home chairs. Background Art

[0002] With the advancement of technology and the extension of working hours, more and more working groups and consumers have put forward diverse requirements for the comfort and versatility of seats. Simple mechanical adjustment is complex and monotonous, and the electrification, activation and intelligent adjustment of seats are becoming more and more important. Utility Model Content

[0003] The utility model provides a motor-driven adjustable seat, which solves the problem that the current simple mechanical adjustment is complicated and monotonous.

[0004] The utility model relates to a motor-driven adjustable chair, comprising a main seat surface, a base and a movable seat surface, and also a motor. Each movable seat surface is controlled in angle position by rotating a separate motor output shaft.

[0005] The motor is fixed at the bottom of the main seat surface, making it easy to install the wires.

[0006] The motor is fixed at the bottom of the movable seat surface, leaving enough installation space for the lifting device at the bottom of the base.

[0007] As a preferred embodiment, the motor is connected to a reducer, and the reducer is fixed to the front of the motor to facilitate driving the movable seat surface and prevent damage to the motor.

[0008] As a preferred embodiment, a connecting piece is fixed at the bottom of the movable chair seat, and a driving shaft for fixing the connecting piece is provided on the reducer, which is convenient for connection and has a simple structure.

[0009] As a preferred embodiment, shafts of the motors on both sides are equipped with shaft position signal collectors, which are connected to a power supply and a signal controller, so that the motors on both sides can be driven synchronously and the movable seat surface can be adjusted synchronously.

[0010] The utility model has the following beneficial effects:

[0011] The movable seat surface can automatically adjust the inclination of the movable seat surface by rotating the output shaft of the motor fixed under the main seat surface, which is more automated, saves manpower, saves adjustment time, and will not pinch the human body.

[0016] The utility model is further described below in conjunction with embodiments.

[0017] Embodiment 1, as Figure 1 to Figure 2 As shown, the utility model is a motor-driven adjustable chair, comprising a main seat surface 6, a base 5 and a movable seat surface 1, and also comprising a motor 8, each movable seat surface 1 is rotated to control the angle position through the output shaft of a separate motor 8. The motor 8 is fixed at the bottom position of the main seat surface 6.

[0018] During operation: when sitting normally, the main seat surface 6 and the movable seat surface 1 have no inclination angle. When the movable seat surface 1 needs to change its angle position, the motor 8 starts to drive the movable seat surface 1 to adjust its angle. After the adjustment is completed, the motor 8 stops.

[0019] Embodiment 2, as Figure 3 As shown, the difference from the first embodiment is that the motor 8 is fixed at the bottom of the movable seat surface 1, so that sufficient space is reserved at the bottom of the base 5 to install the lifting structure.

[0020] Embodiment 3, based on embodiment 1 or 2, the motor 8 is connected to a reducer 3, and the reducer 3 is fixed at the front of the motor 8.

[0021] A connector 2 is fixed at the bottom of the movable seat surface 1, and a drive shaft 9 for fixing the connector 2 is provided on the reducer 3. The drive shaft 9 is a D-shaped shaft, which is fixed on the reducer 3. A bracket is provided at the lower end of the connector 2, and a D-shaped hole matching the D-shaped shaft is provided on the bracket.

[0022] The shafts of the motors 8 on both sides are equipped with shaft position signal collectors 7, which are connected to a power supply and a signal controller 4. The shaft position signal collectors 7 are Hall signal collectors, which detect the position of the rear shaft of the motor 8 during adjustment, thereby determining the inclination angle of the movable seat surfaces 1 on both sides, thereby achieving synchronous control and adjustment of the movable seat surfaces 1 on both sides.

[0023] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0024] In the description of the present invention, the terms "inside", "outside", "longitudinal", "lateral", "upper", "lower", "top", "bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.
