DETAILED DESCRIPTION [0018] A wireless charging device 10 according to disclosure implementations can be a wireless charging base or a chip system. The following will describe in detail the wireless charging device 10 according to implementations of the disclosure with reference to FIG. 1.
[0019] As illustrated in FIG. 1, the wireless charging device 10 includes a wireless transmission circuit 12, a transmission coil 14 and a control circuit 16. In the following, the shapes and functions of components within the wireless charging device 10 will be elaborated.
Petition 870190077087, of 08/09/2019, p. 12/63
5/29 [0020] Wireless transmission circuit 12 is configured to transmit a wireless charging signal through transmission coil 14. Wireless transmission circuit 12 may include a high frequency oscillator circuit. The wireless transmission circuit 12 can generate a high frequency oscillation signal based on the high frequency oscillator circuit and transmit the high frequency oscillation signal outwards through the transmission coil 14, to form the wireless charging signal. .
[0021] The transmission coil 14 includes multiple pairs of joints (a joint is formed by a wire taken from a certain position of the transmission coil 14), where the coil turns defined by each pair of joints are different (here, turns transmission coil). The position of a joint in the transmission coil 14 can be flexibly adjusted according to actual needs. For example, the joint can be located in one or more of the following positions on the transmission coil 14: a start position, an end position and any position between the start position and the end position. Each of the multiple pairs of joints of the transmission coil 14 can define the transmission coil of certain turns. The transmission coil defined by a pair of joints in this document refers to a transmission coil with one joint of the pair of joints as a starting position and the other joint of the pair of joints as an end position.
[0022] The number of gasket pairs included in the transmission coil 14 is not particularly limited here. For example, two pairs of joints can be included, or three
Petition 870190077087, of 08/09/2019, p. 13/63
6/29 or more pairs of joints can be included.
[0023] FIG. 2 illustrates a possible design of the transmission coil. As illustrated in FIG. 2, the transmission coil 14 includes three joints, that is, Joint 1, Joint 2 and Joint 3 illustrated in FIG. 2. Joint 2 is located in the starting position (or in the innermost position) of the transmission coil 14. Joint 1 is located in the final position (or in the outermost position) of the transmission coil 14. Joint 3 is located in an intermediate position (that is, a position between the starting position and the ending position) of the transmission coil 14.
[0024] As illustrated in FIG. 2, the transmission coil 14 includes two pairs of joints, that is, a pair of joints including Joint 1 and Joint 2 (hereinafter referred to as a second pair of joints or a second pair of joints) and a pair of joints including Joint 2 and Joint 3 (referred to as a first pair of joints or a first pair of joints to follow). In one example, the transmission coil 14 includes N turns, where N is a positive integer greater than 1. Since Joint 1 is located in the innermost position of the transmission coil 14 and Joint 2 is located in the outermost of the transmission coil 14, Joint 1 and Joint 2 define an N-turn transmission coil (i.e., all transmission coil turns 14). Since Gasket 3 is located in the middle position of the transmission coil 14, the transmission coil turns defined by Gasket 2 and Gasket 3 are less than N.
[0025] The control circuit 16 is configured to select one of the multiple pairs of joints to be
Petition 870190077087, of 08/09/2019, p. 14/63
7/29 electrically coupled with the wireless transmission circuit 12. The wireless transmission circuit 12 will transmit a wireless charging signal to the outside through a transmission coil defined by the pair of gaskets that is electrically coupled to the transmission circuit wireless 12. Still taking FIG. 2 as an example, if wireless transmission circuit 12 is electrically coupled to the second pair of joints (ie, Joint 1 and Joint 2), wireless transmission circuit 12 will transmit the wireless charging signal to the outside via the entire transmission coil 14 (including N transmission coil turns). If wireless transmission circuit 12 is electrically coupled to the first pair of joints (ie, Joint 2 and Joint 3), wireless transmission circuit 12 will transmit the wireless charging signal to the outside via a transmission coil located between Board 2 and Board 3 (less than N turns).
[0026] As long as the above control function can be achieved, the shape of the control circuit 16 is not limited here. As an example, the control circuit 16 can include a microcontroller unit (MCU) and a switching circuit. The switching circuit alternates between different pairs of joints under the control of the MCU.
[0027] The way in which the control circuit 16 selects one of the multiple pairs of joints to be electrically coupled with the wireless transmission circuit 12 is not specifically limited here. For example, control circuit 16 first selects a pair of joints that define which larger transmission coil turns work. If excessive heat is produced by the
Petition 870190077087, of 08/09/2019, p. 15/63
8/29 wireless charging device 10, the control circuit 16 can then select a pair of joints that define smaller transmission coil turns to work to reduce the heat produced during work [0028] The transmission coil 14 provided in This document includes multiple pairs of joints, and control circuit 16 can select and switch between multiple pairs of joints according to current needs, which makes wireless charging more flexible.
[0029] The following describes in detail one possible way in which one of the multiple pairs of joints is selected.
[0030] The wireless charging device 10 can be operated in a first wireless charging mode or a second wireless charging mode. A charging speed at which the wireless charging device 10 charges a device to be charged in the first wireless charging mode is greater than in the second wireless charging mode.
[0031] In other words, compared to the wireless charging device 10 operating in the second wireless charging mode, the wireless charging device 10 operating in the first wireless charging mode takes less time to fully charge the battery. capacity of the device to be loaded 230.
[0032] The second wireless charging mode can be called normal wireless charging mode and can be, for example, a conventional wireless charging mode based on the IQ standard, PMA (power matters alliance) standard or alliance standard for wireless power (A4WP). 0
Petition 870190077087, of 08/09/2019, p. 16/63
9/29 first wireless charging mode can be called fast wireless charging mode. The normal wireless charging mode may refer to a wireless charging mode in which the wireless charging device 10 has a low transmission power (typically less than 15W and the commonly used transmission power 5W or 10W). In normal wireless charging mode, it usually takes several hours to fully charge a high capacity battery (like 3000mA). However, in the fast wireless charging mode, the transmission power of the wireless charging device 10 is relatively high (typically greater than or equal to 15W). In comparison to the normal wireless charging mode, in the fast wireless charging mode, the wireless charging device 220 can fully charge a battery with the same capacity in a substantially shorter charging period and charging is faster. [0033] The control circuit 16 can be configured to: control a first pair of joints between the multiple pairs of joints to be electrically coupled with the wireless transmission circuit to make the wireless transmission circuit 12 transmit a charging signal wirelessly through the transmission coil defined by the first pair of joints, when the wireless charging device 10 charges the device to be charged in the first wireless charging mode; controlling a second pair of joints between multiple pairs of joints to be electrically coupled with the wireless transmission circuit to make wireless transmission circuit 12 transmit a wireless charging signal
Petition 870190077087, of 08/09/2019, p. 17/63
10/29 through the transmission coil defined by the second pair of joints, when the wireless charging device 10 charges the device to be charged in the second wireless charging mode, where the transmission coil turns defined by the first pair of joints is less than those defined by the second pair of joints.
[0034] Taking the transmission coil 14 illustrated in FIG. 2 as an example, the second pair of joints corresponds to Joint 1 and Joint 2 and defines the entire transmission coil 14; the first pair of joints corresponds to Joint 2 and Joint 3 and
define part gives coil in streaming 14. When O device in loading wireless 10 carries O device a to be loaded at the second mode in loading wireless, the circuit of control 16 can to control O circuit of streaming without wire 12 to be coupled electrically with the Board 1 and Gasket 2 for do all The
transmission coil 14 works. When wireless charging device 10 charges the device to be charged in the first wireless charging mode, control circuit 16 can control wireless transmission circuit 12 to be electrically coupled with Board 2 and Board 3 to form part the transmission coil 14 works.
[0035] Longer turns of the transmission coil defined by a pair of joints can lead to higher impedance of the transmission coil. When wireless charging device 10 works in the first wireless charging mode, since charging the wireless charging device 10 in the first wireless charging mode is faster, the heating of the charging coil
Petition 870190077087, of 08/09/2019, p. 18/63
11/29 transmission will be severe if the impedance of the transmission coil in a working state is high. Therefore, in order to reduce the heating of the transmission coil, when the wireless charging device 10 is in the first wireless charging mode, the first pair of gaskets will be controlled to function, thereby reducing the impedance and heating of the transmission coil. in the working state. To reduce the inductance due to smaller coil turns, a transmission voltage can be increased to compensate for this reduction in inductance, for example. When wireless charging device 10 operates in the second wireless charging mode, the second pair of gaskets will be controlled to function.
[0036] Besides the wireless transmission circuit 12, the transmission coil 14 and the control circuit 16 described above, the wireless charging device 10 can also be equipped with circuits with other functions according to the real needs, what is not limited hereinafter Below, several possible implementations of the wireless charging device 10 will be described in detail with reference to FIGs. 3 and 4.
[0037] As illustrated in FIG. 3, the wireless charging device 10 further includes a voltage conversion circuit 18. The voltage conversion circuit 18 is configured to receive an input voltage and convert the input voltage to obtain an input voltage and an input current from the wireless transmission circuit 12. Control circuit 16 is further configured to communicate wirelessly with the device to be charged during wireless charging to adjust a power
Petition 870190077087, of 08/09/2019, p. 19/63
12/29 transmission of the wireless transmission circuit 12, to make the transmission power of the wireless transmission circuit 12 correspond to a charging voltage and / or a charging current currently required by a battery of the device to be charged . [0038] With the help of the voltage conversion circuit 18 it is possible for the wireless charging device 10 to adjust a voltage received by the wireless transmission circuit 12 according to the actual needs. For example, wireless charging device 10 needs to transfer energy with high voltage and small current, and this energy transfer has high requirements on the input voltage (such as 10V (volt) or 20V) of the wireless transmission circuit 12. If the minimum output voltage of an external power supply device is unable to meet the input voltage requirements of wireless transmission circuit 12, voltage conversion circuit 18 may cause the input voltage of transmission circuit 12 cord reaches an expected input voltage. Alternatively, if the output voltage of the external power supply device can satisfy the input voltage requirements of wireless transmission circuit 12, voltage conversion circuit 18 can be omitted, to simplify the implementation of the charging device without wire 10.
[0039] As illustrated in FIG. 4, the device
loading without thread 10 includes still an interface in loading 13. THE interface charging 13 is configured for to be coupled to a device in
external power supply 20. The input voltage

13/29 received by the voltage conversion circuit 18 is provided by the power supply device 20 via the charging interface 13. In this implementation, the control circuit 16 is further configured to communicate with the power supply device 20 for adjusting an output voltage and / or an output current of the power supply device 20 to adjust the transmission power of the wireless transmission circuit 12.
[0040] In one implementation, the charging interface 13 is a universal serial bus (USB) interface. The type of the loading interface 13 is not particularly limited here. As an example, charging interface 13 is a USB interface and the USB interface can be, for example, a USB 2.0 interface, a micro USB interface or a USB TYPE-C interface. In another implementation, the charging interface 13 can also be a lighting interface, or other types of parallel interface and / or serial interface that can be used for charging.
[0041] The mode of communication between the control circuit 16 and the power supply device 20 is not limited here. As an example, the control circuit 16 can be coupled and communicate with the power supply device 20 via a communication interface other than the charging interface. As another example, control circuit 16 can communicate wirelessly with power supply device 20. For example, control circuit 16 can perform near field communication (NEC) with the
Petition 870190077087, of 08/09/2019, p. 21/63
14/29 power supply device 20. Still as another example, control circuit 16 can communicate with power supply device 20 via charging interface 13 and no other communication interface or communication module is required without wireless, which can simplify the implementation of wireless charging device 10. As an implementation, charging interface 13 is a USB interface. The control circuit 16 can communicate with the power supply device 20 via a data line (such as a D + line and / or a D- line) from the USB interface. As another implementation, charging interface 13 is a USB interface that supports a power delivery communication (PD) protocol (such as the USB TYPE-C interface). The control circuit 16 can communicate with the power supply device 210 based on the communication protocol PD.
[0042] The wireless charging device 10 illustrated in FIG. 3 receives a power charge from the external power supply device 20. Unlike the wireless charging device 10 illustrated in FIG. 3, the function of the power supply device 20 is integrated into the wireless charging device 10 illustrated in FIG. 4, that it is possible to decrease the number of devices needed for wireless charging and improve the integration of the wireless charging device 10.
[0043] The wireless charging device has been described in detail above. In the following, a device to be loaded will be elaborated with reference to the implementations

In addition to implementations of the present disclosure, the device to be charged or terminal may also include a power bank. The power bank can be charged by a wireless charging device and thus store energy to charge other electronic devices.
[0045] As illustrated in FIG. 5, a device to be loaded 30 of implementations of the disclosure includes a receiving coil 32, a wireless receiving circuit 34 and a control circuit 36.
[0046] The receiving coil 32 is configured to receive a wireless charging signal from a wireless charging device. The receiving coil 32 includes multiple pairs of joints, where different pairs of joints define different turns of the receiving coil. A joint is formed by a wire extracted from a specific position of the receiving coil 32. The position of a joint in the receiving coil 32 can be flexibly adjusted according to actual needs. For example, the joint can be located in one or more of the following positions on the receiving coil 32: a start position, an end position and any position between the start position and the end position. Each of the multiple pairs of joints of the receiving coil 32 can define the receiving coil of certain turns.

In one example, the receiving coil 32 includes N turns, where N is a positive integer greater than 1. Since Joint 1 is located in the innermost position of the receiving coil 32 and Joint 2 is located in the outermost of the receiving coil 32, Joint 1 and Joint 2 define a Nvolta receiving coil (i.e., all receiving coil turns 32). Since Joint 3 is located in the middle position of the receiving coil 32, the receiving coil turns defined by Joint 2 and Joint 3 are less than N.

19/29 [0053] The way in which the control circuit 36 selects one of the multiple pairs of joints to be electrically coupled with the wireless receiving circuit 34 is not limited here.
