Problems solved by technology

[0004] However, when the user places the device to be charged on the wireless charging base, it often happens that the placement position of the structural coil of the device to be charged deviates from the generating coil of the wireless charging base.
After this happens, the efficiency of electromagnetic energy transmission decreases due to the decrease in the coupling degree between the transmitting coil and the receiving coil, and the transmitting coil needs to provide more energy to maintain the charging power of the receiving coil
Due to the offset of the device to be charged, the transmitting coil needs to emit more energy, which causes the wireless charging base to heat up, which affects the stable operation of the system and the charging speed
When the device to be charged is placed too far away, it will cause the charging failure of the wireless charging base or the failure of the trigger, resulting in the inability to charge, etc.

Abstract

The invention provides a wireless charging base and a control method of the wireless charging base. The wireless charging base comprises a base body, a motion mechanism, a charging module, and an image acquisition module, wherein the base body is configured to carry the device to be charged, the motion mechanism is located in the base body, the charging module is moveably set in the motion mechanism, the image acquisition module is configured to acquire position image information of the device to be charged on the base body, and the motion mechanism makes the charging module move to the bottomof the device to be charged according to the position image information. The charging module of the wireless charging base can be aligned with the charging coil of the device to be charged to ensurethe charging efficiency of the wireless charging base to the charging device.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a wireless charging base and a control method for the wireless charging base. Background technique [0002] Wireless charging technology originates from wireless power transmission technology, which can be divided into low-power wireless charging and high-power wireless charging. Since energy is transmitted between the charger and the device to be charged by a magnetic field, there is no wire connection between the two. [0003] At present, most of the wireless chargers on the market are wireless charging bases, the wireless charging base is provided with a transmitting coil, and the device to be charged is provided with a receiving coil. When the device to be charged is wirelessly charged, the positions of the transmitting coil of the wireless charging base and the receiving coil of the device to be charged are aligned to ensure smooth charging. [0004] However, when the user...
