Description

Technical Field

[0001] The present application relates to the field of wireless charging technology, and in particular to a portable wireless charging and transmitting device. Background Art

[0002] Wireless charging transmitters mainly work based on electromagnetic induction, magnetic field resonance or radio waves. For electromagnetic induction wireless charging, the transmitter generates a changing magnetic field through a coil. When the receiving device (such as a mobile phone) approaches, the coil inside it will sense these magnetic field changes and convert them into current, thereby charging the battery. Magnetic field resonance wireless charging uses the resonance principle to achieve efficient energy transmission.

[0003] The wireless charging transmitter needs to receive power when in use, and the power starts the coil to power the device. Considering that the connection terminal needs to be powered by a wire, a data cable is still used to supply power to the wireless charging transmitter, which causes the data cable to affect the storage when the wireless charging transmitter is carried. In the prior art, a torsion spring is set to retract the data cable. When the data cable is connected, the use distance is limited.
