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 invention discloses a wireless power receiving / charging device and a wireless power receiving / charging system, and belongs to the field of wireless charging. The wireless power receiving device comprises n power receiving coils, a receiver, a charging management chip and a battery, wherein n is a positive integer greater than 1; the output ends of the n power receiving coils are connected withthe input end of the receiver, the output end of the receiver is connected with the input end of the charging management chip, and the output end of the charging management chip is connected with thebattery; the receiver is used for obtaining the power receiving proportion of the n power receiving coils, the power receiving proportion of the ith power receiving coil is related to the coupling coefficient between the charging coils, and i is larger than or equal to 1 and smaller than or equal to n. By arranging the plurality of 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, so that the battery of the wireless power receiving device can becharged, the effective placement range of the wireless power receiving device on the wireless charging device is relatively large, and the placement freedom degree is relatively high.
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...
