Abstract: A furniture accessory includes an armrest body and an insertion plate moveably coupled to the armrest body and configured for mounting to a furniture item. The furniture accessory may include a power output assembly for receiving and providing power to a detachable electrical accessory. The furniture accessory may include a power input interface and a power supply circuit for providing power from an external power source to the power output interface.

Abstract: An exemplary supporting audio element for a furniture item may include a control circuit positioned within a body portion, a supporting leg, and a loudspeaker. The supporting audio element may be mounted to a furniture item, for supporting the furniture item, and configured for one or more of, without limitation, communicating with an external audio device, playing audio, controlling a function of the furniture item, voice recognition, and voice control. An exemplary supporting audio element may include a microphone connected to a phonetic recognition module, for receiving and recognizing voice commands and relaying the voice commands to the control circuit for controlling a function of the supporting audio leg and the furniture item. A furniture item may include an exemplary supporting audio element for incorporating the features thereof.

Abstract: A furniture accessory may include an armrest body and an insertion plate moveably coupled to the armrest body and configured for mounting to a furniture item. A moveable cover plate may provide access to a hollow interior of the armrest body. The furniture accessory may include a power output assembly for receiving and providing power to a detachable electrical accessory. The furniture accessory may include a power input interface and a power supply circuit for providing power from an external power source to the power output interface.

Abstract: An eccentric column structure of a waist twisting exercise machine is provided which includes a base, a cushion, and an eccentric column assembled between the base and the cushion. The cushion is supported above the base through the eccentric column, so that the seat height of the cushion is slightly higher than the height of knees of an average adult, thereby enabling riding in a relatively comfortable and ergonomic posture, and enabling exercising movements of rotating and waist twisting by using two feet landing on the ground as points of force application. In addition, the eccentric column is integrally formed by a bending processing of a metal pipe column, which not only avoids the formation of seams during assembly or structural weaknesses derived from welding, but also greatly enhances the overall strength of the structure, thereby being conducive to prolonging the service life and safety of the exercise machine.

Abstract: A drive control system for a linear driver may include a power module, a controller, a motor drive module, a motor, and a position control module. The power module may be connected to the controller, the controller may be connected to the motor drive module, and the position control module may be connected in series between the controller and the motor drive module to form a control loop. The power module may be connected to the motor drive module to input power to the motor drive module, and the motor drive module may be connected to the motor to form a drive loop. The control loop may control the work of the drive loop, and the drive loop may directly form a loop in series connection with the motor and the power module through the motor drive module.

Abstract: A furniture item includes a main body with an electrical device installed thereon. A power line electrically connects the electrical device to an external power source and is concealed in a power line channel formed in one or more of the walls of the main body. A switch may be connected to the main body and electrically connected to the electrical device, for controlling the electrical device. A main body door moveable from a first position to a second position may trigger the switch to enable and disable electrical connection between the external power source and the electrical device.

Abstract: An electrical connector for electrically coupling an electrical accessory to a furniture item may include a support column and a power interface set that may be provided in an interior of the support column. The power interface set may include an electrically contactable lower surface that may be spaced apart from an end of the support column. A distance between the electrically contactable lower surface of the power interface set and the end of the support column may be equal to a length of a retention portion of the support column. The retention portion and the electrically contactable lower surface of the power interface set may be together dimensioned for connection to an external power source coupled to the furniture item.

Abstract: A support base includes a connector hub having a top end, a bottom end spaced apart from the top end, and a chamber wall extending between the top and bottom ends. The chamber wall defines a chamber within the connector hub. An interface may be positioned in the chamber. The interface is dimensioned such that a support gap is formed between the interface and the chamber wall. The support gap may be dimensioned for receiving a wall of a support structure having a hollow interior into which the interface is received.
