The following describes the specific structure and operation principle of the wireless charging/discharging device with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a circuit block diagram of a wireless charging/discharging device 10 according to a first embodiment of the present invention. In this embodiment, the wireless charging/discharging device 10 is a mobile communication device, such as a mobile phone or a tablet computer. The wireless charging/discharging device 10 includes a display screen for displaying images and a back case located right above the display screen.
As shown in fig. 1, the wireless charging and discharging device 10 includes an energy storage unit 11, a processing unit 12, a transmission control unit 13, a receiving control unit 14, a first coil 15, a second coil 16, a magnetic core 17, a gravity sensing unit 18, and a command receiving module 19.
The energy storage unit 11 is used for storing externally provided electric energy and outputting the stored electric energy to other electronic devices.
The processing unit 12 is electrically connected to the transmitting control unit 13, the receiving control unit 14, the gravity sensing unit 18 and the command receiving module 19, and the processing unit 12 is configured to receive the charging signal or the discharging signal and output a corresponding control signal to the transmitting control unit 13 and the receiving control unit 14 according to the charging signal or the discharging signal, so as to control the transmitting control unit 13 to work in cooperation with the first coil 15 or control the receiving control unit 14 to work in cooperation with the second coil 16. The charging signal and the discharging signal can be from the gravity sensing unit 18 or from the command receiving module 19.
The transmission control unit 13 is electrically connected to the first coil 15, that is, the first coil 15 is electrically connected to the processing unit 12 through the transmission control unit 13; the receiving control unit 14 is electrically connected to the second coil 16, and the second coil 16 is electrically connected to the processing unit 12 through the receiving control unit 14. The first coil 15 and the second coil 16 share the magnetic core 17 and do not operate simultaneously, whereby the first coil 15 cooperates with the magnetic core 17 to generate an electromagnetic effect and the second coil 16 cooperates with the magnetic core 17 to generate an electromagnetic effect. In this embodiment, the first coil 15 and the second coil 16 are enameled wires.
Specifically, the gravity sensing unit 18 is configured to sense a current position state of the wireless charging/discharging device 10, that is, determine that the wireless charging/discharging device 10 is currently with a display screen facing upward or downward according to the acquired Z-axis value, or determine that the wireless charging/discharging device 10 is currently with a display screen closer to or farther from the user than the back housing.
The gravity sensing unit 18 outputs a corresponding charging signal or discharging signal to the processing unit 12 according to the current position state of the wireless charging and discharging device 10.
In this embodiment, when the display screen of the wireless charging and discharging device 10 faces downward, it indicates that the wireless charging and discharging device 10 needs to output an electrical signal to an external device for discharging, so as to charge the external device, and is in a discharging mode; when the display screen of the wireless charging and discharging device 10 faces upward, it indicates that the wireless charging and discharging device 10 receives the output electric signal of the external device to charge itself, and is in a charging mode.
Then, when the range of the acceleration value of the Z axis acquired by the gravity sensing unit 18 is-9.5 to-10, it indicates that the current position state of the wireless charge and discharge device 10 is screen down, indicating that the wireless charge and discharge device 10 needs to be in the discharge mode, and therefore, the acceleration value of the Z axis between-9.5 and-10 is provided to the processing unit 12 as a discharge signal, and correspondingly, the processing unit 12 outputs the first control signal to the transmitting unit 13 and the receiving control unit 14 according to the discharge signal. Preferably, the acceleration value of the Z axis is-9.8, which indicates that the current position state of the wireless charging and discharging device 10 is that the display screen faces downward.
When the range of the acceleration value of the Z axis acquired by the gravity sensing unit 18 is not within-9.5 to-10, it indicates that the current position state of the wireless charging and discharging device 10 is that the display screen is facing upward, and it indicates that the wireless charging and discharging device 10 needs to be in the charging mode, so that the acceleration value of the Z axis not within-9.5 to-10 is provided to the processing unit 12 as a charging signal, and correspondingly, the processing unit 12 outputs a second control signal to the transmitting unit 13 and the receiving control unit 14 according to the charging signal.
When receiving the first control signal sent by the processing unit 12, the emission control unit 13 controls the first coil 15 to work, and the first coil 15 cooperates with the magnetic core 17 to send the electric energy signal of the energy storage unit 11 to the outside of the wireless charging and discharging device 10, so as to achieve the purpose of discharging, and thus, external electronic equipment is charged. At this time, the receiving control unit 14 controls the second coil 16 to stop operating when receiving the first control signal corresponding to the discharging signal sent by the processing unit 12.
The receiving control unit 14 controls the second coil 16 to work when receiving a second control signal corresponding to the charging signal sent by the processing unit 12, and the second coil 16 cooperates with the magnetic core 17 to receive an electrical signal from the outside of the wireless charging and discharging device 10, convert the electrical signal into an induced current, and transmit the induced current to the energy storage unit 11 for storage, so as to achieve the purpose of charging.
The specific mating process for the gravity sensing unit 18 and the processing unit 12 is as follows:
the preset mode of the wireless charging and discharging device 10 is a charging mode, that is, the default state of the wireless charging and discharging device 10 is the charging mode, that is, the processing unit 12 receives the charging signal by default, and outputs the second control signal to the transmitting control unit 13 and the receiving control unit 14 correspondingly, wherein the transmitting control unit 13 controls the first coil 15 to pause, and the receiving control unit 14 controls the second coil 16 to be in the working state. At this time, if an external device provides an electrical signal, the second coil 16 cooperates with the magnetic core 17 to receive the electrical signal and transmit an induced current generated by an electromagnetic induction principle to the energy storage unit 11.
When the gravity sensing unit 18 sends the obtained sensing data to the processing unit 12, and the processing unit 12 determines that the current position of the wireless charging and discharging device 10 is located with the display screen corresponding to the discharging mode facing downward according to the sensing data, it indicates that the processing unit 12 receives the discharging signal, and the wireless charging and discharging device 10 enters the discharging mode from the charging mode, that is, the processing unit 12 outputs a first control signal to the sending control unit 13 and the receiving control unit 14 corresponding to the discharging signal, so as to start the first coil 15 to be in the working state and control the second coil 16 to stop working.
Preferably, the wireless charging and discharging device 10 may output a prompt message to inform the user that the wireless charging and discharging device 10 is in the discharging mode currently, for example, output and display a corresponding prompt message from a display screen or set a charging indicator lamp such as a discharging indicator lamp for display. Meanwhile, the charge indicator lamp and the discharge indicator lamp may have the same flickering frequency, wherein the discharge indicator lamp is turned on when the wireless charging and discharging device 10 enters the discharging mode and flickers at a predetermined frequency, and the flickering frequency of the discharge indicator lamp may be preset.
Preferably, within the first preset time, when the gravity sensing unit 18 determines that the position state corresponding to the discharging state of the wireless charging and discharging device 10 is not changed and the wireless charging and discharging device 10 and the electronic device to be charged meet the preset condition, for example, the wireless charging and discharging device 10 and the electronic device to be charged are located at the preset distance or the verification information is successfully transmitted to each other, that is, after the handshake is successful, the wireless charging and discharging device 10 keeps the discharging mode unchanged.
Preferably, when the wireless charging and discharging device 10 and the electronic device to be charged do not conform to the preset condition, the wireless charging and discharging device 10 maintains the discharging mode within a second preset time, and when the wireless charging and discharging device 10 and the electronic device to be charged do not conform to the preset condition even after the second preset time is exceeded, the wireless charging and discharging device 10 is switched to the charging mode; when the wireless charging/discharging device 10 and the electronic device to be charged meet the preset condition again within the second preset time, the wireless charging/discharging device 10 still maintains the discharging mode.
Preferably, when the gravity sensing unit 18 determines that the position state corresponding to the discharging state of the wireless charging and discharging device 10 changes, for example, changes to a state where the display screen faces upward, but no electronic device to be charged meeting the preset condition exists, the wireless charging and discharging device 10 maintains the discharging mode within the second preset time and performs discharging according to the preset discharging threshold. The discharge threshold may be set according to actual requirements, for example, 30%, 50%, 80%, 100%. If the wireless charging/discharging device 10 and the electronic device to be charged meet the preset condition within the first preset time, the wireless charging/discharging device 10 still maintains the discharging mode. The charging indicator lamp and the reference indicator lamp are in the same flickering frequency.
The command receiving module 19 receives the operation of the user to generate an operation command corresponding to the operation, and outputs a corresponding charging signal or discharging signal to the processing unit 12 according to the operation command.
