Abstract

The invention belongs to the technical field of wireless energy transmission, and particularly relates to a magnetic coupling mechanism of a sliding ring. The magnetic coupling mechanism comprises anelectromagnetic coupling mechanism, wherein the electromagnetic coupling mechanism comprise an external cylinder coil, an external cylinder magnetic core, an internal cylinder coil and an internal cylinder magnetic core, and wireless energy transmission can be achieved. By coaxially sleeving an energy emission mechanism and an energy receiving mechanism, the wireless energy transmission of the energy emission mechanism and the energy receiving mechanism can be achieved in a relatively rotation system the groups of magnetic strips are controlled by losing a part of magnetic shielding performance and controlling maximum magnetic induction intensity of the magnetic cores under the condition that the magnetic cores cannot reach magnetic saturation, and the mass of the coupling mechanism is reduced to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission, and in particular relates to a slip ring magnetic coupling mechanism. Background technique [0002] At present, the fixed part and the rotating part of most machines realize the transmission of electric energy through the sliding contact of conductive slip rings, such as solar sail panel drive device (SADA), drone camera, stage lights, etc. when the relevant parts need to rotate Both adopt the contact method of conductive slip ring device to realize energy transmission, but there are certain problems in energy transmission in this way. On the one hand, the slip ring is easily damaged once it is subjected to a large vibration during operation; The life of the ring is easy to decrease. In addition, the interior of the conductive slip ring is generally very complicated, and the process requirements are high, so the cost is high. Therefore, the traditional conductive slip ring ca...
