Abstract
An induction coil structure (10), comprising at least one layer of induction coil (100). The at least one layer of induction coil (100) is formed by winding a wire (101); the number of turns of each layer is 3-20; the maximum outer diameter is 10-100 millimeters; the diameter of the wire (101) is 0.1-5 millimeters; and the inductance of the induction coil (100) itself is 5-30 microhenries. A wireless charging apparatus (20), comprising a coil matching circuit (200) for generating an induced current, a chip peripheral circuit (210) which is connected to the coil matching circuit (200) and is used for rectifying the induced current, and an output interface circuit (220) which is connected to the chip peripheral circuit (210) and is used for outputting the rectified induced current to a device to be charged so as to achieve charging.
Description
technical field [0001] The invention relates to wireless charging technology, in particular to an induction coil structure and a wireless charging device. Background technique [0002] With the development of wireless charging, the demand for 2W wireless charging of smart wearable devices is becoming more and more intense. However, according to the market requirements for smart wearable devices such as miniaturization, refinement, and diversification, the wireless charging receiver coils and motherboards equipped inside must be To meet this requirement, coils and main boards are gradually developing in the direction of miniaturization and diversified shapes. At the same time, it is necessary to ensure the convenience of charging, high charging sensitivity and efficiency, so that the equipment to be charged can be charged more conveniently and faster. In order to improve the user experience, there must be a transmitter supporting the receiver to meet these requirements. [0...
