Problems solved by technology

However, the power generated by the multiple second transmission coils 34 below the multiple first transmission coils 33 is partially shielded by the multiple first transmission coils 33, so that this part of the power cannot be transmitted to the closed receiving coil 21, which will cause waste of electricity
That is, the existing wireless charging transmission device 3 has the disadvantage of low power usage

Abstract

The invention discloses a wireless charging transmission apparatus. The wireless charging transmission apparatus comprises a body, a first enclosed transmission coil and a second enclosed transmission coil. The first enclosed transmission coil and the second enclosed transmission coil are arranged in the body; the second enclosed transmission coil is adjacent to the first enclosed transmission coil; and the first enclosed transmission coil and the second enclosed transmission coil are both quadrangles so as to enable magnetic flux generated by the short side sections of the first enclosed transmission coil and the second enclosed transmission coil to be greater than magnetic flux generated by a circular enclosed transmission coil. Therefore, the wireless charging transmission apparatus provides a larger wireless charging scope.

Description

technical field [0001] The present invention relates to a charging transmission device, and in particular to a wireless charging transmission device utilizing wireless charging technology. Background technique [0002] Various electronic devices must be connected to a power supply to obtain power before they can be used. Generally speaking, electronic devices are plugged into a power source (such as a power socket) by a power cord to obtain power. With the development of science and technology, various electronic devices have become thinner and lighter in response to the needs of users, so as to be easy to carry. Due to the portable nature of the electronic device, the electronic device cannot rely on the power line to obtain power at any time. Therefore, a rechargeable battery must be arranged in the electronic device to provide power to the electronic device. [0003] When the power of the rechargeable battery in the electronic device is insufficient, the user uses a cha...
