Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found the following problems in the current technology: accurate alignment is required between the sending coil of the wireless charger and the receiving coil of the device to be charged in the existing Qi standard, and inaccurate alignment will lead to charging Low efficiency, affecting use
At this stage, since the coil of the wireless charger is fixed, it is usually used to mark the charging position on the wireless charger to remind the user to place the device to be charged. This is not only troublesome, but also due to the variety of devices to be charged, the wireless charger It is difficult to match a variety of different devices to be charged, and the user experience is poor

Abstract

The invention discloses a wireless charger and a charging control method thereof. The wireless charger comprises a metal lattice, a driving module and a controller, wherein the metal lattice, the driving module and the controller are electrically connected with a power supply module. The metal lattice comprises a plurality of metal points. Adjacent metal points in the metal lattice are connected through a controllable switch. The control end of the controllable switch is connected with the driving module. The controller generates a first control signal to the driving module. The driving module drives the controllable switches in a first area of the metal lattice according to the first control signal for realizing conduction so that the metal points in the first area of the metal lattice are started for forming a first transmitting coil. According to the wireless charger and the charging control method thereof, through forming the coil by means of connecting the plurality of metal points and adjusting the controllable switches, charging coil position adjustment can be realized, thereby realizing free placement of to-be-charged equipment in the wireless charger, realizing high suitability for different kinds of to-be-charged equipment, and improving wireless charging availability and user experience.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charger and a charging control method thereof. Background technique [0002] Wireless charging technology is a technology that uses magnetic resonance to transmit charges in the air between the charger and electronic products, and coils and capacitors form resonance between the charger and electronic products to achieve efficient power transmission. At present, the methods that can realize this technology include the electromagnetic induction coupling method of the Qi standard, the radio wave method, and the electromagnetic resonance method proposed by MIT (Massachusetts Institute of Technology). [0003] In the process of realizing the present invention, the inventors found the following problems in the current technology: accurate alignment is required between the sending coil of the wireless charger and the receiving coil of the device to be charged in the...
