Title:
WEARABLE NON-CONTACT POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2023147984
Kind Code:
A
Abstract:
To provide a technique which realizes high power transmission efficiency regarding a technique for transmitting power from a battery attached to a belt that a user wears to an electric device.SOLUTION: A non-contact power supply system comprises a belt that a person wears, and a relay. The belt includes a power transmitting coil, which is connected to a battery, and a first magnet. The relay is mounted on clothing that the user wears along with the belt. The relay includes a power receiving coil, a terminal connected to the power receiving coil, and a second magnet. The first/second magnets and the power transmitting/receiving coils satisfy the following positional relation. Namely, when the second magnet is attracted to the first magnet by a magnetic force, the power transmitting coil and the power receiving coil face each other. In the non-contact power supply system, non-contact power transmission is performed between the belt and the relay, and the power transmitting coil and the power receiving coil are accurately face each other by the first magnet and the second magnet, thereby realizing high power transmission efficiency between the power transmitting and power receiving coils.SELECTED DRAWING: Figure 1
