A vehicle having an electrical drive wheel hub system (30) and the hub system incorporated in the vehicle has a wheel hub (18) driven by an electric motor (31) formed by a brushless DC motor having stators (40) and rotors (42). The electric motor is arranged to drive an epicyclic gear system (32) which provides a reduction gear arrangement to drive the hub (18). Located entirely within the periphery of the stator is power circuitry and control circuitry for the electric motor, the circuitry being provided on toroidal printed circuit boards (70, 71).

A chassis for a tracked mobility device may include: a battery box floor; a battery box rear wall; a pair of main side rails; a main front cross member; a lower box rear cross member; a pair of side bogie support tubes; a pair of motor support tubes; rear side support tubes; front side support tubes; a pair of bogie support plates; short bogie cross tubes; seat frame plates; a tensioner support frame; a rear cross support plate; motor/gear boxes having floors, rear walls, outer side walls, inner side walls, and outer side wall extensions/gussets; anti-tip tubes; anti-tip cross-members; and anti-tip vertical tie rods. The chassis components may be welded together to provide a rigid, stable, unitary construction.

A mobility device that can accommodate speed sensitive steering, adaptive speed control, a wide weight range of users, an abrupt change in weight, traction control, active stabilization that can affect the acceleration range of the mobility device and minimize back falls, and enhanced redundancy that can affect the reliability and safety of the mobility device.

A mobility assistance apparatus includes first and second frames positioned on left and right sides of a user; a hinge arm mechanism coupled to the first and second frames; and a securing unit or a walking seat coupled to the frames to transfer at least a portion of the user's body weight from the legs and to transfer weight through the user's hip or pelvis to the first and second frame enabling the user to stand or work for an extended period without requiring the user's arms to hold the frame.

It becomes possible to monitor a driven state of each wheel in a wheelchair whose wheels are driven according to output information calculated based on input information. A left wheel controller and a right wheel controller are provided. The presence or absence of a drive abnormality of the left wheel is determined by the right wheel controller receiving first drive related information that is related to a drive of the left wheel and transmitted from the left wheel controller, and the presence or absence of a drive abnormality of the left wheel is determined by the left wheel controller receiving second drive related information that is related to a drive of the right wheel and transmitted from the right wheel controller.

A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

The present invention discloses a moving mechanism including a support; a driving device mounted on the support; a controller arranged on the support; two sets of moving assemblies respectively mounted at two ends of the support; wherein each of the moving assemblies includes a track and two synchronous wheels of different diameters arranged inside the track, such that the moving mechanism could be functioned and run freely over stairs, rugged road surface and all-terrain ground under the action of the driving device and the controller. The present invention also discloses electric vehicles and toys equipping the moving mechanism. The moving mechanism of the present invention overcomes shortcomings of conventional moving mechanisms by making use of a breakthrough composite structure of a half-wheel-half-track configuration in combination with an additional omni-directional wheel, whereby the moving mechanism and the electric vehicles and toys equipping the same are adaptable to different road surfaces and stairs of various angles, and also very convenient and reliable to use.

The present invention is a smart electric wheelchair for the elderly, which comprises a battery for power supply and a control system for integrally controlling the electric wheelchair, and also comprises a body bracket, wherein the bottom of the body bracket is connected with a standing platform for a user to stand, a driving unit is provided on each side of the standing platform to drive the electric wheelchair; and a foldable seat is provided in the middle of the body bracket, and an armrest is provided on each side of the seat, with at least one of the armrests provided with a controller for controlling the entire electric wheelchair. The electric wheelchair is provided with a plurality of sensors which include a ranging and positioning sensor and/or an obstacle avoidance sensor, and further include an identification sensor, wherein the identification sensor identifiably corresponds to a one-to-one mobile identification device worn by a user, so that the electric wheelchair can automatically follow the user's position according to the collaboration between the mobile identification device and the sensor. The present invention solves the drawbacks of existing similar apparatuses and gives the elderly a better use experience, showing both practical and economical significance.
