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 includes a power module, a metal dot matrix, a driving module and a controller. Adjacent metal points in the metal dot matrix are connected through controllable switches. The controller receives a wireless charging instruction, generates a first control signal and sends the first control signal to the driving module. The driving module drives the controllable switches in the first region of the metal dot matrix to be switched on according to the first control signal so that metal dots in the first region of the metal dot matrix switch on to form a first transmitting coil. According to the wireless charger and the charging control method thereof, the position of a charging coil can be adjusted by connecting the metal dots to form the coil and adjusting the controllable switches so that a device to be charged can be freely placed in the wireless charger. The wireless charger is adaptable to different devices to be charged and improves the usability and the user experience of wireless charging.

Description

technical field [0001] The invention relates to the field of electronic technology, 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 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 existi...
