Wireless-powered receiving coil with direction adaptability

A wireless-powered receiving coil with direction adaptability belongs to the technical field of electromagnetic wave power supply or power distribution systems and is used for gastrointestinal tract robots. The wireless-powered receiving coil with the direction adaptability comprises a first coil assembly, a second coil assembly, a bias magnetic core portion and a rotating self-orientating mechanism, wherein the first coil assembly and the second coil assembly are arranged on the bias magnetic core portion orthogonally and in a winding mode and are respectively connected with a peripheral circuit; the bias magnetic core portion is arranged on the rotating self-orientating mechanism; and the rotating self-orientating mechanism enables angles of deflection of the first coil assembly and the second coil assembly to change, and accordingly enables the two coil assemblies to receive magnetic fields of any direction. The wireless-powered receiving coil with the direction adaptability enables the coils to be capable of maintaining a receiving gesture through the rotating self-orientating mechanism so that the stability of the space gesture is improved; and is simple in structure, easy to manufacture, low in cost, reliable in performance and relatively high in energy receiving efficiency.
