Embodiment Construction

[0022] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] First, a charging prompt method according to an embodiment of the present invention will be described.

[0024] The charging prompt method of the embodiment of the present invention is applied to various electronic devices such as tablet computers and smart phones. The electronic device includes a wireless charging receiving unit such as a receiving coil, so that it can be charged by wireless charging. That is, the electronic device serving as the receiving end of wireless charging receives electric energy from the wireless charging device serving as the transmitting end of wireless charging through electromagnetic induction. The principle of wireless charging is known to those skilled in the art and will not be described in detail here. In addition, the electronic device further includes an output unit configured to output information to the us...

Abstract

The invention provides a charging prompting method for electronic equipment and the electronic equipment. The charging prompting method comprises the steps that when a wireless charging apparatus is coupled with the electronic equipment, the magnetic field strength in each of multiple predetermined points of the electronic equipment is detected independently; a first relative position relation between the electronic equipment and the wireless charging apparatus is calculated based on the detected multiple magnetic field strengths; and prompting is carried out for a user of the electronic equipment based on the first relative position relation.

Description

technical field [0001] The present invention relates to the field of electronic equipment, and more specifically, the present invention relates to an electronic equipment and a charging prompt method. Background technique [0002] In recent years, more and more electronic devices have adopted wireless charging technology to simplify charging lines and improve user experience. However, in the current wireless charging technology, the efficiency of wireless charging is low when the receiving end and the transmitting end are misaligned, and the heat generation is serious. [0003] In view of the above problems, in an existing wireless charging technology, a permanent positioning magnet is added to the center of the coil at the transmitting end to locate the relative positional relationship between the receiving end and the transmitting end. However, this wireless charging method will affect the coil coupling parameters, which may cause the magnetic flux saturation of the magne...
