Embodiment Construction
[0051]Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.
[0052] figure 1 It is a block diagram showing the structure of a wireless power receiving device according to an exemplary embodiment. Such as figure 1 As shown, the wireless power receiving device 11 includes: a power receiving coil 111 , a receiver 112 , a charging management chip 113 and a battery 114 .
[0053] The wireless power receiving device 11 is an electronic device that c...

The disclosure discloses a wireless power receiving / charging device and system, belonging to the field of wireless charging. The wireless power receiving device includes: n power receiving coils, a receiver, a charging management chip, and a battery, where n is a positive integer greater than 1; the output terminals of the n power receiving coils are connected to the input terminals of the receiver, and the receiver's The output terminal is connected to the input terminal of the charging management chip, and the output terminal of the charging management chip is connected to the battery; the receiver is used to obtain the power receiving ratio of the n receiving coils, and the power receiving ratio of the i-th receiving coil and the charging coil The coupling coefficient is related, where 1≤i≤n. By setting multiple power receiving coils, when the wireless power receiving device is placed on the wireless charging device for charging, only one of the power receiving coils needs to correspond to the charging coil to charge the battery of the wireless power receiving device. The effective placement range of the powered device on the wireless charging device is relatively large, and the degree of freedom of placement is relatively large.
Description
technical field [0001] The present disclosure relates to the field of wireless charging, and in particular to a wireless power receiving device, a wireless charging device and a system. Background technique [0002] Wireless charging technology is used in charging various mobile terminals such as mobile phones, tablets, and notebook computers. [0003] A wireless charging technology is provided in the related art. The wireless charging technology includes a wireless charging device and a wireless power receiving device. The wireless charging device includes a charging coil, and the wireless power receiving device includes a power receiving coil and a battery. [0004] However, when performing wireless charging at present, since the charging coil and the power receiving coil need to be placed correspondingly, when the position deviation between the charging coil and the power receiving coil is large, the charging cannot be continued, and the wireless power receiving device is...
