Problems solved by technology
[0003] For the above situation, although the existing technology realizes the unidirectional detection of whether the wireless charging receiving device is placed on it by the wireless charging transmitter, the reverse situation cannot be realized, that is, the detection of the wireless charging receiving device by the wireless charging receiving device cannot be realized. Whether it is placed in the wireless charging transmitter or not, furthermore, the existing technology is still unable to realize the two-way detection of the existence of the wireless charging receiving device and the wireless charging transmitter

Embodiment Construction
[0028] Before discussing the exemplary embodiments in greater detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowchart depicts the operations as a sequential process, many of the operations may be performed in parallel, concurrently, or concurrently. Additionally, the order of operations can be rearranged. The process may be terminated when its operation is complete, but may also have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, subroutines, and the like.
[0029] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the exemplary embodiments. As used herein, the singular forms "a", "an" and "an" are intended to include the plural unless the context clearly dictates otherwise. It should also be understood that the terms "comprising" and / or "compri...

The present application provides a method and device for detecting that a wireless charging receiving device is placed in a wireless charging transmitter. The method includes: detecting that the state of the wireless charging receiving device satisfies a specific condition during the process of charging the wireless charging receiving device by the wireless charging transmitter. Condition, send a command to stop charging to the wireless charging transmitter; in response to the sending of the stop charging command, determine whether a scheduled interruption event generated on the wireless charging receiving device is detected; if the scheduled interruption event is detected, then detect the The wireless charging receiving device is placed on the wireless charging transmitter. Otherwise, it is detected that the wireless charging receiving device is not placed on the wireless charging transmitter. According to the technical solution of the present application, it is possible for the wireless charging receiving device to detect whether it is placed on the wireless charging transmitter.
Description
technical field [0001] The present application relates to wireless charging of electronic devices, and in particular, to a method and apparatus for detecting that a wireless charging receiving device is placed in a wireless charging transmitter. Background technique [0002] At present, as far as the field of wireless charging is concerned, when a wireless charging receiving device (such as a mobile phone, smart watch, etc.) is placed in a wireless charging transmitter (such as a wireless charging base) for charging, if the wireless charging receiving device meets certain conditions, such as charging Completed, overheated or overcurrent, etc., the wireless charging receiving device will send a stop charging command to the wireless charging transmitter. In this case, although the wireless charging transmitter stops charging the wireless charging receiving device, it will periodically send The wireless charging receiving device transmits a detection signal for detecting whethe...
