Abstract

The invention provides a self-guiding wireless charger and a working method thereof. The wireless charger comprises a base and a transmitting disc, and the base and the transmitting disc are connectedthrough a transmission device; a sensor array is arranged on the transmitting disc and is used for acquiring the positions of an outer frame and a wireless receiving coil of a to-be-charged mobile phone; a control module is arranged in the base, and the control module is connected with the sensor array; the control module controls the transmission device to correct the position of the transmitting disc according to the outer frame of the mobile phone to be charged and the position of the wireless receiving coil, and the transmitting disc is aligned with the mobile phone to be charged. The invention has the beneficial effects that a mobile phone can be automatically aligned, so the mobile phone can automatically realize position correction under the condition that the mobile phone touchesthe emitter or the mobile phone deviates and cannot be charged, and then automatic charging is carried out.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a self-guiding wireless charger and a working method thereof. Background technique [0002] At present, wireless charging has been widely used in the field of mobile phones. The use of traditional wireless chargers is that the user places the mobile phone on the wireless transmitter, and then judges whether it is in the correct position according to the prompts of the mobile phone. However, if the transmitter is accidentally touched or the mobile phone is shifted, it may not be able to charge. Contents of the invention [0003] The invention provides a self-guided wireless charger and its working method, which are used to solve the situation that charging may not be possible due to offset caused by touching a transmitter or a mobile phone. [0004] A self-guided wireless charger, characterized in that it includes: a base and a launching plate, the base and the launch...
