摘要： Disclosed is a drive unit for a wheelchair and a wheelchair including such. The wheelchair includes a control input and a structural frame with two lateral frame elements, each supporting a drive wheel. The drive unit includes two drive motors within a driveshaft housing, adapted to drive the drive wheels independently based on input via the control input. The drive shaft housing is releasably attached between the two lateral frame elements of the wheelchair and connected to the drive wheels via quick-release couplings. The drive shaft housing is divided into at least two sections, each section housing one of the drive motors and that the at least two sections of the drive shaft housing are telescopically moveable relative to each other for adjusting the width of the drive shaft housing to different wheelchairs having different distances between the lateral frame elements of the structural frame of the wheelchair.

摘要： The presently disclosure describes a system for a providing an assistive driving force to a wheelchair. The system comprises a power assist system which includes a motion sensing system that is configured to detect the motion of the power assist system, and hence of the wheelchair, and a power assist drive system that is configured to provide an assistive drive force. The system also comprises a sensor, such as may be embedded in a wearable wristband, that is configured to detect the motion of a user's hand and that is in communication with the power assist system. The system may be configured to determine whether the wheelchair is being manually pushed based at least in part on the user motion, and to activate an assistive drive force in response to a manual push. The system may also be configured to determine whether the wheelchair is being manually braked based at least in part on the user motion, and to deactivate an assistive drive force in response to a manual brake.

摘要： A swing arm assembly for a foldable wheelchair consisting of a camber tube and adapters is disclosed. The adapters mount to the frame of the wheelchair and receive the ends of the camber tube. One end of the camber tube is pinned into an adapter such that it pivots. The other end is pinned in an adapter using a quick release pin. The camber tube improves the stability of the foldable wheelchair. When desired to fold the wheelchair, the quick release pin is removed and the camber tube is rotated approximately 90 degrees, thereby allowing the wheelchair to fold. The adapters may be mounted to the wheelchair frame or to stub axles if used. The swing arm assembly adds substantial stiffness and stability to a folding wheelchair.

摘要： An improved walker has a detachable propulsion unit, which is attached to the walker by a platform member which extends forwardly from the propulsion unit, with an upwardly extending walker structure partially attached to the platform member. The user steps onto the propulsion unit while support on either side by the handles of the walker. The platform member is so attached to the propulsion unit as to allow a left section and a right section of the propulsion unit to be independently movable with respect to one another, thereby allowing operation of the propulsion unit. The propulsion unit may be a hover board or power board.

摘要： A method for electrically assisting with the propulsion of a rolling system comprising a driving wheel driven by an electric motor, the torque applied by the motor being a function of a propulsion torque transmitted by a user to the driving wheel, wherein the method comprises: a preliminary step of storing in memory an unknown input model representing the weighted system, which is a function of the geometry and of the mass of the weighted system, and having as output data the rotational speed of the driving wheel; a step of estimating unknown input being the total torque applied to the wheel, influencing the rotational speed, the total torque being estimated from the rotational speed by calculating the inverse model; the propulsion torque transmitted by the user being deduced from the total torque estimated on the basis of the other known torques that make up the total torque.

摘要： A motion-based push activation power assist system for manual wheelchairs. The system uses motion-based measurements to determine when the user applies a push to the wheelchair handrims and brakes with the handrims. The push recognition activates a drive system that provides an assistive driving force-pulse to the wheelchair to reduce the demand on the user during propulsion. The brake recognition deactivates the power assist. The provided power assist is proportional to the sensed push and can be modulated to different proportional settings.
