Positioning method for recharging, self-moving equipment and body positioning system

A positioning method for self-moving equipment, the self-moving equipment comprising a body and a plurality of inductors distributed in a triangular configuration, the method comprising:

• autonomously moving the self-moving equipment toward a positioning device, the positioning device comprising a base and a coil assembly installed on the base, the coil assembly comprising a triangular positioning element;
• and
• locating a position of the body relative to the base by sensing a positioning inductance generated through electromagnetic induction between the plurality of inductors and the triangular positioning element, wherein the position is located when each inductor is induced within a corresponding angle of the triangular positioning element such that a circular induction range of each inductor is inscribed within the corresponding angle of the triangular positioning element.

A positioning device for locating a position of a self-moving equipment, the positioning device comprising:

• a base;
• and
• a coil assembly installed on the base, the coil assembly comprising a triangular positioning element configured to electromagnetically induce with a plurality of inductors on the self-moving equipment distributed in a triangular configuration to generate a positioning inductance, wherein the triangular positioning element is dimensioned such that a circular induction range of each of the inductors is inscribable within a corresponding angle of the triangular positioning element when the self-moving equipment is positioned on the base.
