Embodiment 1

[0023] In order to make the received energy even when parallel to the axis of the magnetic ring and when the magnetic field direction is perpendicular to the axial direction of the magnetic ring, the outer diameter of the magnetic ring is determined, and the value of H can be obtained according to the calculation formula.

[0024]

[0025] This embodiment is a receiving coil for wireless power supply, including: a hollow cylindrical magnetic ring 1 used as a magnetic core, and a three-dimensional coil 2 wound on the hollow cylindrical magnetic ring 1, wherein: the three-dimensional coil 2 includes several excitation wires, each The winding start points of the excitation wires are separated by 120° on the circumference of the end face of the hollow cylindrical magnetic ring 1, so that the three-dimensional coil 2 receives energy in three dimensions, and the winding shape of each excitation wire on the hollow cylindrical magnetic ring 1 is Elliptic curve shape.

Abstract

The invention discloses a wireless power supplied receiving coil in the endoscope technical field. The wireless power supplied receiving coil comprises a hollow cylindrical magnetic ring serving as a magnetic core, and a three-dimensional coil body wound on the hollow cylindrical magnetic ring, wherein the three-dimensional coil body comprises a plurality of magnet exciting wires, the distance of the winding initial points of every two magnet exciting wires is 120 degrees on the circumference of the end face of the hollow cylindrical magnetic ring so that the three-dimensional coil body can receive energy of three dimensions, and the winding of each magnet exciting wire on the hollow cylindrical magnetic ring is in an elliptic curve shape. The hollow cylindrical magnetic ring serves as the cylindrical magnetic core, so that a circuit board of a capsule is placed in the hollow magnetic core, and accordingly the length of a video image capsule endoscope is effectively shortened.

Description

technical field [0001] The invention relates to a device in the field of endoscope technology, in particular to a receiving coil for wireless power supply. Background technique [0002] The acceleration of people's life rhythm and the change of diet structure have led to an increasing incidence of digestive tract diseases. According to statistics, the total incidence of digestive system diseases accounts for 30% of the population, and 1 / 2 of the outpatients in major hospitals are digestive system diseases. Among them, those who need emergency admission account for about 25% of the patients admitted to the emergency department; worldwide, the number of deaths due to digestive system diseases accounts for 14% of the total number of deaths. Endoscopy is an effective method commonly used clinically at present, and plays an extremely important role in the diagnosis of gastrointestinal diseases. The traditional endoscope enters the body through a guiding cannula, which will cause...
