Magnetic coupling structure for wireless charging and autonomous underwater vehicle system

Abstract

The invention discloses a wireless charging magnetic coupling structure and an autonomous underwater vehicle. The magnetic coupling structure is applied to an autonomous underwater vehicle, and includes a transmitting end arranged on a charging dock and a receiving end arranged on an autonomous underwater vehicle, the transmitting end includes a transmitting coil and is arranged at a distance from the transmitting coil. A launch core on one side of the autonomous underwater vehicle. The invention can help the autonomous underwater vehicle realize seabed wireless charging, and solves the problems of poor battery life and difficult charging of the autonomous underwater vehicle. At the transmitting end of the magnetic coupling structure, a transmitting magnetic core is arranged on one side of the transmitting coil, which reduces the limitation of the transmitting magnetic core on the transmitting coil and increases the flexibility of the transmitting coil; and the magnetic core at the transmitting end is compatible with the autonomous underwater vehicle. There is a distance between them to prevent seawater pressure from changing the parameters of the transmitting magnetic core, thereby improving the adaptability of the system to underwater wireless charging.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a magnetic coupling structure of wireless charging and an autonomous underwater vehicle system. Background technique [0002] There are a lot of biological resources and mineral resources in the ocean, but human beings still know very little about the ocean. Autonomous underwater vehicle AUV (Autonomous underwater vehicle) is an important tool to help humans understand and explore the ocean. In recent years, although AUV has played an important role in marine national defense security, marine environmental observation, and marine resource exploration. However, due to the limitation of AUV's own size and load capacity, the battery capacity is limited, and the battery life problem has always limited the further development of AUV. There are two traditional methods for charging AUVs: the first is to salvage the AUV to the mother ship every time the battery is exhausted, ...

AI Technical Summary

Problems solved by technology

However, due to the limitation of AUV's own volume and load capacity, the battery capacity is limited, and the battery life problem has always limited the further development of AUV.

At present, some magnetic coupling devices for wireless charging of AUVs have been proposed. At the transmitting end, the transmitting coil is often wound on the transmitting magnetic core, causing the shape and number of turns of the transmitting coil to be limited by the transmitting magnetic core, resulting in the setting of the transmitting coil. Restricted; and when charging on the seabed, the transmitting core and the AUV are basically bonded. Affected by seawater pressure, the shell at the transmitting end is squeezed, which directly causes the transmitting core to be compressed or even deformed, resulting in the magnetic permeability of the transmitting core.
