This is directed to a smart ergonomic chair and mobility system. The system can be used as a working station, a working chair, a mobility device, a personal care device, or a combination thereof. The system is designed to provide ergonomic seating posture for a person who is seated on the chair. The system is also designed to reduce body stress by providing automatic movements of parts of the chair at predefined time points.

A lift mechanism self-locking push rod is provided, which comprises a drive component, a transmission component, and a lift component, and a self-locking device is disposed between the drive component and the transmission component; a power input shaft of the transmission component is sleeved into a one-way bearing; a first locking piece and a second locking piece are disposed around the one-way bearing; the first locking piece is fixedly connected with the one-way bearing, and the second locking piece rotatably cooperates with the one-way bearing; the first locking piece is abutted against the second locking piece; a resistance is generated between abutting surfaces of the first locking piece and the second locking piece for the purpose of locking. The resistance between the abutting surfaces helps to achieve the locking effect while the entire structure not be rotated and the length of the lift component not be changed.

A length-adjustable support having a telescopic column assembly that includes a rotatable spindle rod configured to telescope an interior tube into and out of an exterior tube, or vice versa, of the telescopic column assembly in order to adjust the length of the length-adjustable support. The column assembly is illustratively attached to a motor housing containing a motor that rotates the spindle rod. In illustrative embodiments, a portion of the spindle rod is attached to the motor housing via a bushing member comprising two complimentary bushing components that surround the spindle rod and support a spindle plate that mates with the spindle rod to rotate therewith. The motor assembly is configured to substantially float within the motor housing and is attached to a flange of the housing by a clip or grommet that retains an attachment arm of the motor assembly.
