Embodiment Construction

[0051] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0052] figure 1 is a schematic structural diagram of a wireless charger shown according to an exemplary embodiment of the present disclosure, as shown in figure 1 As shown, the wireless charger includes a power supply module 5 , a wireless transmitting module 4 and a transmitting coil 3 . In addition, the wireless charger also includes a magnet 1 and a starting module 2 .

[0053] The magnet 1, set in such as figure 1The transmitting coil 3 of the wireless charger shown is used to provide a magnetic field around the transmitting coil 3 . Since the receiving coil on the device to be charged is made of metal, when the device to be charged moves close to the ...

Abstract

The invention relates to a wireless charger and a wireless charging system and relates to the technical field of wireless charging. The wireless charger comprises a power module, a wireless transmission module, a transmitting coil, a magnet and a starting module, wherein the magnet is arranged in the transmitting coil and is used for providing a magnetic field around the transmitting coil; the starting module is connected with the power module, the wireless transmission module and the transmitting coil separately and is used for starting the power module to provide the wireless transmission module with working voltage when the transmitting coil generates first voltage due to a change in the magnetic field; and the working voltage is used for driving the transmitting coil to work to carry out wireless charging on equipment which needs to be charged. Immediate discharge and immediate charge of the wireless charger can be really achieved, and the equipment which needs to be charged can beautomatically charged when close to the transmitting coil, so that the user experience is improved, the situation that the transmitting coil needs to be in the working condition all the time to achieve immediate discharge and immediate charge is avoided and power consumption of the wireless charger in free time is greatly reduced.

Description

technical field [0001] The present disclosure relates to the technical field of wireless charging, and in particular, to a wireless charger and a wireless charging system. Background technique [0002] At present, a variety of electronic devices have begun to have the function of wireless charging. For a wireless charger connected to the mains, in order to realize instant charging, the transmitting coil used for charging in the wireless charger is usually kept working, and because the power consumption of the transmitting coil is usually large, if the wireless charger Connecting to the mains all the time will cause serious power consumption and waste power resources, and for the case of wireless charging using a mobile power supply, since the power of the mobile power supply is limited, the continuous operation of the transmitting coil will seriously affect the normal use of the mobile power supply . Therefore, in the case of using a mobile power supply for wireless chargi...
