The present invention provides a movable vehicle. The movable vehicle comprises a carrying mechanism and a holding mechanism connected to the carrying mechanism, and the bottom of the carrying mechanism is provided with wheels, wherein the movable vehicle further comprises a starting mechanism arranged on the holding mechanism, the starting mechanism comprising a starting unit, a power supply unit, and a controller. The starting unit is configured to be switchable between an initial position and a start position. The controller is configured to be electrically connectable to the power supply unit, wherein when the starting unit is in the start position, the starting unit is coupled to the controller to activate the electrical connection between the controller and the power supply unit, and when the starting unit is in the initial position, the starting unit is decoupled from the controller. According to the above solution, a user can easily activate the electrical connection between the controller and the power supply unit simply by operating the starting unit on the holding mechanism, thereby allowing the controller to further perform various control operations.

A weight-bearing device includes a single wheel, a frame attached to the wheel, and an electric motor attached to the frame. The electric motor is configured to rotate a first gear, connected to a second gear with a chain. The second gear is connected to the wheel. The second gear and the first gear may have a gear ratio of greater than 8:1.

A hand-driven, wheeled carrier deceleration device, applied to an axle of a hand-driven, wheeled carrier, is introduced and has a wheel, driven gear, reluctance motor and resistive component. The wheel, pivotally disposed at the axle, has a drive gear which rotates together with the wheel. The driven gear, disposed beside the axle, meshing with and driven by the drive gear, has a connection portion. The reluctance motor, connected to the connection portion and driven by the driven gear, has permanent magnets and metal elements. The metal elements and permanent magnets are arranged annularly. The metal elements rotate relative to the permanent magnets. The resistive component electrically connects to the permanent magnets. Therefore, a driving force exerted on the hand-driven, wheeled carrier is partially offset by reluctance to effectively slow down the hand-driven, wheeled carrier.

A walk-behind vehicle includes a vehicle body assembly, a driving wheel, a power assembly, a braking assembly, a control assembly and a power supply device. The driving wheel is connected on the vehicle body assembly. The power assembly is mounted in the driving wheel. The braking assembly is arranged on the driving wheel. The control assembly is arranged on the vehicle body assembly and is electrically coupled to the power assembly and the braking assembly. The power supply device is arranged on the vehicle body assembly and is electrically coupled to the power assembly, the braking assembly and the control assembly. The control assembly includes a steering control device, which is electrically connected with the power assembly in the driving wheel on both sides of the vehicle body assembly and configured for controlling a steering of the driving wheel on both sides of the vehicle body assembly.

A transfer device includes an automated guided vehicle, a positioning platform, and a positioning transmission mechanism. The automated guided vehicle is provided with a supporting frame; the positioning platform is arranged on the supporting frame.
