Abstract: 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.

Abstract: A pallet jack power assembly upgrades a manually powered pallet jack to provide a motor-driven drive wheel. In one example, the manually powered pallet jack includes left and right steering wheels separated by a narrow distance. A frame of the pallet jack power assembly may be adapted for attachment to the pallet jack. The frame supports a drive axle, which in turn supports a drive wheel. Attachment of the frame of the pallet jack power assembly locates the drive wheel between the left and right steering wheels. The drive axle and a steering axle, supporting the left and right steering wheels of the pallet jack, may be located in a same vertical plane. A biasing device, such as a spring, may be used to provide a downward force on the drive wheel, thereby increasing friction between the drive wheel and the floor.

Abstract: A front-wheel motor powered golf trolley comprised of a compact backward tricycle-wheel arrangement and a lightweight stiff open truss chassis. Left and right front wheel assemblies, driven by common drive axle, motorized through silent motor speed reduction, pull the trolley in an easily guided walk-along fashion. The driven front wheels are compliantly isolated from the chassis by sprung front axle support arms. Trolley stance stabilization and steering are by an independently sprung rear wheel/pivot assembly, the pivot being located between the front drive and rear wheel axles. A steering handle is the user-guiding interface and location for all hand operated controls. Upper and lower golf bag supports fold out from the chassis. Stow-ability is compact and without bulkiness. This trolley is adaptable to remote control of power, steering, and braking functions. The trolley also accommodates multiple other user conveniences.

Abstract: A wheel includes a hub having a number of teeth formed on one end. A cam is rotatably supported on one end of the hub. An axle is rotatably engaged in the hub and has one end engaged with the cam. A spring biases the axle to engage with the cam. A coupler is rotatably engaged on the axle and includes a key for engaging with the teeth of the hub when the spring biases the axle toward the cam, and the key is disengaged from the teeth when the axle is moved against the spring by the cam. The wheel can be applied to push carts or applied to motor vehicles.

Abstract: Wheeled cart carries one-way electric motor, battery for energizing motor, and one-way transmission for driving wheels. Transmission includes belt loosely trained about pulleys, and a roller engageable with belt to make it taut so that it transmits motion from motor to wheels; disengagement of roller from belt allows cart to be rolled backwardly. Handle includes two telescoping parts, inner part being connected to a rheostat which controls amount of current supplied to motor. Pulling force on outer end of handle determines setting of rheostat and speed of motor.
