Abstract
A motorised trolley with a traction wheel, an assisting motor, a clutch, a speed sensor and a motor controller. The assisting motor engages when accelerating beyond an activation speed and disengages when decelerating below the activation speed. The assisting motor disengages when the motorised trolley accelerates beyond a maximum speed and re-engages when decelerating below the maximum speed. The assisting motor engageably-disengages when the rotational speed exceeds a maximum motor speed. A power source may include power-tool batteries.
Claims20
A motorised trolley (100) comprising:
- a traction wheel (110) positionable over a guiding structure (50);
- an assisting motor (120) connected to the traction wheel (110) via a clutch (130);
- a speed sensor (140) measuring a rotational speed of the traction wheel (110);
- and
- a motor controller (150) electrically attached to the assisting motor (120) and the speed sensor (140).
A method (200) for operating a motorised trolley (100), the method comprising:
- engaging (230) an assisting motor (120) when the motorised trolley (100) accelerates along a guiding structure (50) beyond an activation speed;
- and
- disengaging (220) the assisting motor (120) when the motorised trolley (100) decelerates along the guiding structure (50) below the activation speed.
A non-transitory computer-readable medium storing a set of instructions for operating a motorised trolley (100), the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a device, cause the device to:
- engage (230) an assisting motor (120) when the motorised trolley (100) accelerates along a guiding structure (50) beyond an activation speed;
- and
- disengage (220) the assisting motor (120) when the motorised trolley (100) decelerates along the guiding structure (50) below the activation speed.
