A method for controlling an electric hand truck includes determining whether user manipulation is present due to a user input on the electric hand truck; and, if there is no user manipulation, then braking an electric motor that drives the wheels of the electric moving vehicle in a softlock manner in which, instead of power being applied to the electric motor, electrodes of the electric motor are short-circuited.

A cart may include: a driving wheel; a motor configured to rotate the driving wheel; a motor drive circuit configured to drive the motor; a motor brake circuit configured to electrically brake the motor; a rotation speed sensor configured to detect a rotation speed of the motor; and a control device configured to control the motor via the motor drive circuit and the motor brake circuit based on a target rotation speed of the motor and the rotation speed detected by the rotation speed sensor. The motor brake circuit may include an electronically variable resistance element configured to operate in a linear mode and a switching mode in response to a control input signal. The motor brake circuit may be configured to operate. the electronically variable resistance element in the linear mode when braking the motor.

A cart may include a driving wheel, a motor configured to rotate the driving wheel, a motor drive circuit configured to drive the motor, a motor brake circuit configured to electrically brake the motor, a control device configured to control the motor via the motor drive circuit and the motor brake circuit so that a travelling speed of the cart becomes equal to or lower than an upper limit travelling speed, and a temperature sensor configured to detect a temperature of the motor brake circuit. The control device may be configured to change the upper limit travelling speed to a second upper limit travelling speed lower than the first upper limit travelling speed when the upper limit travelling speed is a first upper limit travelling speed and the temperature detected by the temperature sensor exceeds a first predetermined temperature.

A tugger cart system used in an industrial setting, including a tugger cart and a controller. The tugger cart includes a tugger frame, a bay that is dimensioned to receive a rider cart, a platform configured to secure a rider cart within the bay, and at least one motor that pivots a plurality of wheels from side to side to steer the plurality of wheels. The tugger frame further includes a connector bracket that pivots from side to side along a vertical axis. The connector bracket is configured to attach the tugger frame to an adjacent tugger cart or tugger truck. A sensor system senses a degree that the connector bracket is pivoted relative to the tugger frame and generates an electronic signal. The controller receives the electronic signal from the sensor system and controls the motor to steer the plurality of wheels based on the electronic signal.

A walking aid vehicle (1) includes: an operation part (3) provided on an upper portion of a vehicle body for grasping by a user in a walking posture; a detector (30) for detecting an operation force applied to the operation part; and an inclination detector (20) for detecting inclination of the vehicle body. When an advance direction inclination detected by the detector is less than threshold, a normal control (100) generates a normal direction torque in the drive motor (40L, 40R) responsive to pushing the operation part (3) forward and generates a reverse direction torque in the drive motor responsive to pulling the operation part rearward, and when the advance direction inclination is equal to or greater than threshold and pushing operation force is detected, a shift to a pull control (110) is made which generates normal direction torque in the drive motor responsive to a pulling operation force.

A motorized riding stroller is provided including a frame having a base platform, a handlebar, and a plurality of legs, wherein the plurality of legs extend from a lower surface of the base platform. The handlebar is pivotally affixed to a rear side of the base platform. An interchangeable seat is removably securable to an upper surface of the base platform. A standing platform is disposed between a pair of rear legs, wherein the pair of rear legs are disposed on opposing lateral sides of the base platform along a rear side thereof. A wheel is affixed to a distal end of each leg of the plurality of legs, wherein each wheel is operably connected to a motor disposed within an interior of the frame. The wheels rotate upon actuation of a drive control disposed on the handlebar, such that the stroller can move in opposing directions.

An autonomously traveling cart system includes a mover, a memory, a position detector, and a processor. The mover moves a cart main body. The memory stores map data indicating an autonomously traveling cart storage space installed in an area where the cart main body is movable. The position detector detects a position of the cart main body. The processor designs a moving route from the position of the cart main body which the position detector detects toward the autonomously traveling cart storage space indicated by the map data, and allows the cart main body to move toward the autonomously traveling cart storage space by the mover.

A load handling device is disclosed for lifting and moving storage containers stacked in a grid framework structure having first and second sets of parallel rails or tracks. The load handling device includes: a body mounted on first and second sets of wheels arranged to engage with the tracks. A direction-change assembly is arranged to raise or lower the first set of wheels and or lower or raise the second set of wheels with respect to the body to engage and disengage the wheels with the tracks. The direction-change assembly includes a linkage-set having a series of members arranged between a traveller and a fixed brace, wherein the traveller is arranged to move under an applied force to cause the wheels to raise or lower.

A drive belt assembly for a load handling device includes a drive belt; a drive wheel; and one or more driven wheels. A first tensioning arm, having a fixed end above an elbow and a rotatable distal end pivotally attached at the elbow, is horizontally displaceable relative to the drive wheel and driven wheels. A second tensioning arm is provided wherein the drive belt is routed around the first and second tensioning arms, and the first and second tensioning arms are arranged to put pressure on the drive belt to tension the drive belt.

The present invention proposes an electric luggage, comprising: a luggage body, an electric chassis, a sensor and a controller. The luggage body is installed on the electric chassis; the front end of the electric chassis is provided with a steerable front handle; the bottom of the front handle is provided with a front wheel; the bottom of the rear end of the electric chassis or the luggage body is provided with a rear wheel; and the speed regulation and braking of the front wheel and/or the rear wheel are controlled through the sensor, the controller, and a battery pack electrically connected with the controller. The luggage body can be combined with the electric chassis to serve as a riding tool. Children can ride the luggage during a journey, which can make parents more relaxed.
