Abstract

The invention relates to a wireless power supply device for gallbladder endoscope, which adopts a magnetic coupling resonant wireless energy transmission and reception mode, including a transmitting coil, a magnetic aggregation low loss iron core, a receiving coil and a coupling enhanced iron core, and a magnetic aggregation low loss iron core. The core includes a thin-axis cylinder of the iron core and circular platforms at both ends of the iron core; the coupling enhanced iron core includes a cylinder in the middle of the iron core and cylinders at both ends of the iron core; the cross-sectional radius R of the thin-axis cylinder of the iron core is related to the emission Coil radius R 1 Equal; the receiving coil is wound close to the cylinder in the middle of the iron core; the cross-sectional radius R of the cylinder in the middle of the iron core 3 with the receiving coil radius R 2 equal; R, R 1 , R 2 and the radius r of the upper bottom surface of the round platform at both ends of the iron core 1 equal; the radius r of the lower bottom surface of the round table at both ends of the iron core 2 is r 1 2.5 times. The invention increases the intensity of the magnetic field passing through the coil, enhances the magnetic coupling effect between the two coils, improves the transmission distance, and can also improve the transmission efficiency.

Description

technical field

[0001] The invention belongs to the technical field of wireless power transmission, and relates to a wireless power supply device for gallbladder endoscope. Background technique

[0002] According to different transmission mechanisms, wireless power transmission technology can be divided into electromagnetic induction, resonance coupling, laser, microwave, electric field coupling, and other methods. Among them, resonant coupling, laser, microwave and other methods can realize medium and long-distance transmission; electromagnetic induction, resonant coupling, laser and other methods can realize high-power transmission. The electromagnetic induction method and the resonant coupling method use the alternating magnetic field generated by the transmitting coil to couple the electric energy to the receiving coil, so as to realize the wireless energy transmission to the load. However, the inductive wireless power transmission technology has relatively strict requi...
