First, when the orientation information of the electronic device is included in the posture information, S120 specifically includes:
when the orientation information is that the first electronic equipment is in a first orientation, the first electronic equipment outputs first electric energy to the second electronic equipment;
and under the condition that the orientation information is that the first electronic equipment is in a second orientation, the first electronic equipment receives second electric energy output by the second electronic equipment.
If the first orientation is north orientation of the electronic device, and the second orientation is south orientation of the electronic device, when the first electronic device is connected to the external electronic device shown in fig. 2, the orientation indicator 260 may display the orientation information of the current power transfer device, and obtain the orientation information of the first electronic device.
The charging process of the first electronic device and the second electronic device is described in detail below with reference to fig. 3-7.
As shown in fig. 3, fig. 3 is a schematic diagram of a charging method according to a first embodiment of the present invention.
The first electronic device 121 is connected to the first interface 230 of the first power transfer apparatus 400, and the second electronic device 122 is connected to the second interface 350 of the second power transfer apparatus 300.
If it is necessary to charge the second electronic device 122 by using the first electronic device 121, the first power transfer device 400 is placed in a first orientation (e.g., a north orientation) and the second power transfer device 300 is placed in a second orientation (e.g., a south orientation) according to the orientation indicator 260 and the orientation indicator 360.
At this time, the power management chip 210 of the first power transfer device 400 controls the electromagnetic induction coil 220 of the first power transfer device 400 to be in the magnetic field releasing state, and the power management chip 310 of the second power transfer device 300 controls the electromagnetic induction coil 320 of the second power transfer device 300 to be in the magnetic field inducing state. At this time, the first electronic device is connected with the second electronic device.
Next, since the first electronic device is connected to the first electric energy relay device, when the first electric energy relay device is placed in a north-facing direction, the posture information of the first electronic device may be acquired as the north-facing direction. Namely, the posture information of the first electronic equipment is judged to meet the first condition.
Therefore, the power management chip 210 of the first power transfer device 400 obtains the power of the first electronic device 121 and transmits the power to the electromagnetic induction coil 220 of the first power transfer device 400, so that the electromagnetic induction coil 220 generates an electromagnetic field, and the electromagnetic induction coil 320 of the second power transfer device 300 in an induced magnetic field state generates an induced current to charge the second electronic device 122. Namely, the first electronic device 121 outputs the first power to the second electronic device 122.
Alternatively, in other embodiments, as shown in fig. 4, fig. 4 is a schematic diagram of a charging method according to a second embodiment of the present invention.
If it is necessary to charge the first electronic device 121 by using the second electronic device 122, the first power transfer device 400 is placed in the second orientation (e.g., the south orientation) and the second power transfer device 300 is placed in the first orientation (e.g., the north orientation) according to the orientation indicator 260 and the orientation indicator 360.
At this time, the power management chip 310 of the second power transfer device 300 controls the electromagnetic induction coil 320 of the second power transfer device 300 to be in the magnetic field releasing state, and the power management chip 210 of the first power transfer device 400 controls the electromagnetic induction coil 220 of the first power transfer device 400 to be in the magnetic field inducing state. At this time, the first electronic device is connected with the second electronic device.
Next, since the first electronic device is connected to the first electric energy relay device, when the first electric energy relay device is placed in a south-facing direction, the posture information of the first electronic device may be acquired as south-facing. Namely, the posture information of the first electronic equipment is judged to meet the second condition.
Therefore, the power management chip 310 of the second power transfer device 300 obtains the power of the second electronic device 122 and transmits the power to the electromagnetic induction coil 320 in the second power transfer device 300, so that the electromagnetic induction coil 320 generates an electromagnetic field, and the electromagnetic induction coil 220 of the first power transfer device 400 in an induced magnetic field state generates an induced current to charge the first electronic device 121. Namely, the first electronic device 121 receives the second power output by the second electronic device 122.
Optionally, in some embodiments, as shown in fig. 5, fig. 5 is a schematic diagram of a charging method according to a third embodiment of the present invention.
The first electronic device 121 is positioned above the first power transfer device 400 and contacts the electromagnetic induction coil 220, and the second electronic device is positioned above the second power transfer device 300 and contacts the electromagnetic induction coil 320.
When it is necessary to charge the second electronic device 122 with the first electronic device 121, the first power transfer device 400 is placed in a first orientation (e.g., a north orientation) and the second power transfer device 300 is placed in a second orientation (e.g., a south orientation) according to the orientation indicator 260 and the orientation indicator 360. At this time, the power management chip 210 of the first power transfer device 400 controls the electromagnetic induction coil 220 of the first power transfer device 400 to be in the magnetic field releasing state, and the power management chip 310 of the second power transfer device 300 controls the electromagnetic induction coil 320 of the second power transfer device 300 to be in the magnetic field inducing state.
Next, the two electric energy relay devices are placed close to each other, so that the electromagnetic induction coil 320 in the second electric energy relay device 300 can induce the electromagnetic field generated by the first electric energy relay device 400, generate an induced current, and charge the second electronic device 122 with the generated induced current. And further the first electronic equipment outputs the first electric energy to the second electronic equipment.
Optionally, in some embodiments, as shown in fig. 6, fig. 6 is a schematic diagram of a charging method according to a fourth embodiment of the present invention.
The first electronic device 121 is positioned above the first power transfer device 400 and contacts the electromagnetic induction coil 220, and the second electronic device is positioned above the second power transfer device 300 and contacts the electromagnetic induction coil 320.
When it is necessary to charge the first electronic device 121 by using the second electronic device 122, it is also necessary to place the second power transfer device 300 in the first orientation (e.g., in the north direction) and the first power transfer device 400 in the second orientation (e.g., in the south direction) according to the orientation indicator 260 and the orientation indicator 360. At this time, the power management chip 310 of the second power transfer device 300 controls the electromagnetic induction coil 320 of the second power transfer device 300 to be in the magnetic field releasing state, and the power management chip 210 of the first power transfer device 400 controls the electromagnetic induction coil 220 of the first power transfer device 400 to be in the magnetic field inducing state.
Next, the two electric energy relay devices are placed close to each other, so that the electromagnetic induction coil 220 in the first electric energy relay device 400 can induce the electromagnetic field generated by the second electric energy relay device 300, generate an induced current, and charge the first electronic device 121 with the generated induced current. And then the first electronic equipment receives the second electric energy output by the second electronic equipment.
In the embodiment of the invention, a user can accurately judge the electronic equipment in the charging state and the electronic equipment in the discharging state through the posture information of the first electronic equipment, and can control the first electronic equipment to output the first electric energy to the second electronic equipment or control the first electronic equipment to receive the second electric energy output by the second electronic equipment through adjusting the posture information of the first electronic equipment according to the own requirements of the user. Therefore, the user can independently adjust whether the electronic equipment is in a charging state or a discharging state, and the use experience of the user is improved.
In some embodiments of the present invention, the power transfer device may be built in the first electronic device and the second electronic device. As shown in fig. 7, fig. 7 is a schematic view of an electronic device according to an embodiment of the present invention.
The electronic device shown in fig. 7 is provided with the power transfer device shown in fig. 2, and when the power transfer device is provided in the electronic device, some structures of the power transfer device may be replaced by a program configured in the electronic device. For example, an electronic compass sensor of the electronic device itself is used to replace a sensor in the power transfer device, so that the power transfer device built in the electronic device is more compact.
If the power transfer apparatus is integrated in an electronic device, and if the first electronic device 121 needs to be used to charge the second electronic device 122, the "power transfer station" mode of the first electronic device 121 and the second electronic device 122 needs to be turned on first.
Next, by rotating the placement orientations of the first electronic device 121 and the second electronic device 122, the electronic compass sensor in the electronic device senses the orientation, and feeds back the current orientation on the electronic device, so as to help the user determine the orientation of the electronic device, so as to determine the charging and discharging state.
The first electronic device 121 may be considered to be in a discharged state when the first electronic device 121 is oriented in a first orientation (e.g., a north-facing orientation), and the second electronic device 122 may be considered to be in a charged state when the second electronic device 122 is oriented in a second orientation (e.g., a south-facing orientation).
Next, the two electronic devices are placed close to each other, and the electronic devices determine whether the first condition is satisfied or the second condition is satisfied according to the orientation of the electronic compass.
When the posture information of the first electronic device 121 satisfies a first condition, the first electronic device 121 outputs a first power to the second electronic device 122;
in a case where the posture information of the first electronic device 121 satisfies the second condition, the first electronic device 121 receives the second power output by the second electronic device 122.
Optionally, in some embodiments of the present invention, a preset control for controlling the electronic device to be a charging party or a discharging party may be configured in the electronic device including the electric energy transfer device.
For example, when the first electronic device 121 is used to charge the second electronic device 122, the first electronic device 121 may be set as a discharging party through a preset control in the first electronic device 121, and the second electronic device 122 may be set as a discharging party through a preset control in the second electronic device 122.
After the first electronic device 121 is set as a discharging side, the power management chip in the first electronic device 121 may control the electromagnetic induction coil in the first electronic device 121 to release the acquired electric energy of the first electronic device 121 in the form of an electromagnetic field. After the second electronic device 122 is set as a charging party, the power management chip in the second electronic device 122 can control the electromagnetic induction coil in the second electronic device 122 to induce the electromagnetic field released by the surrounding first electronic device 121, so as to generate an induced current, and the induced current is used to charge the second electronic device 122.
By the charging method provided by the embodiment of the invention, when a user uses the electronic equipment provided with the electric energy transfer device, under the condition that the electric quantity of the electronic equipment is insufficient, the cross-correlation charging between the electronic equipment can be realized only by another electronic equipment which is also provided with the electric energy transfer device, so that the condition that the user cannot charge the electronic equipment because the user cannot find a power supply is avoided, and the use experience of the user is improved.
Next, when the shielding information of the electronic device is included in the pose information, before S110, the method further includes:
receiving a detection signal sent by a target sensor; wherein the target sensor includes: a pressure sensor or an infrared sensor.
S110 may specifically include:
based on the detection signal, attitude information is acquired. Wherein the pose information comprises occlusion information.
S120 specifically comprises:
under the condition that the shielding information indicates that the first electronic equipment has a shielding object, the first electronic equipment outputs first electric energy to the second electronic equipment;
and under the condition that the shielding information is that the first electronic equipment does not have the shielding object, the first electronic equipment receives second electric energy output by the second electronic equipment.
Optionally, the acquisition of the shielding information may be performed by an infrared sensor or a pressure sensor.
Continuing to refer to fig. 2, the sensor 240 shown in fig. 2 may be an infrared sensor or a pressure sensor.
The first electronic equipment is connected with a first interface of the first electric energy transfer device, and the second electronic equipment is connected with a second interface of the second electric energy transfer device.
If the first electronic device is needed to charge the second electronic device, the second electric energy transfer device is first needed to be stacked above the first electric energy transfer device.
At this time, the power management chip of the first electric energy transfer device controls the electromagnetic induction coil of the first electric energy transfer device to be in a magnetic field releasing state, and the power management chip of the second electric energy transfer device controls the electromagnetic induction coil of the second electric energy transfer device to be in an induced magnetic field state, so that the first electronic device is connected with the second electronic device.
Next, since the first electronic device is connected to the first electric energy relay device, the second electronic device is connected to the second electric energy relay device. Therefore, when the second electric energy relay device is stacked above the first electric energy relay device, the posture information of the first electronic device can be acquired, and the first electronic device is provided with a shielding object. Namely, the posture information of the first electronic equipment is judged to meet the first condition.
Therefore, the power management chip of the first electric energy transfer device can obtain the electric energy of the first electronic device and transmit the electric energy to the electromagnetic induction coil in the first electric energy transfer device, so that the electromagnetic induction coil generates an electromagnetic field, and the electromagnetic induction coil of the second electric energy transfer device in an induced magnetic field state generates an induced current to charge the second electronic device. Namely, the first electronic equipment outputs the first electric energy to the second electronic equipment.
Optionally, in another embodiment, if it is required to charge the first electronic device by using the second electronic device, the first electric energy transfer device is first stacked above the second electric energy transfer device.
At this time, the power management chip of the second electric energy transfer device controls the electromagnetic induction coil of the second electric energy transfer device to be in a magnetic field releasing state, and the power management chip of the first electric energy transfer device controls the electromagnetic induction coil of the first electric energy transfer device to be in an induced magnetic field state, so that the first electronic device is connected with the second electronic device.
Next, since the second electronic device is connected to the second electric energy relay device, the first electronic device is connected to the first electric energy relay device. Therefore, when the first electric energy relay device is stacked above the second electric energy relay device, the posture information of the first electronic device can be acquired, and the first electronic device does not have a shielding object. Namely, the posture information of the first electronic equipment is judged to meet the second condition.
Therefore, the power management chip of the second electric energy transfer device can obtain the electric energy of the second electronic device and transmit the electric energy to the electromagnetic induction coil in the second electric energy transfer device, so that the electromagnetic induction coil generates an electromagnetic field, and the electromagnetic induction coil of the first electric energy transfer device in an induced magnetic field state generates an induced current to charge the first electronic device. Namely, the first electronic device receives the second electric energy output by the second electronic device.
In the embodiment of the invention, a user can accurately judge the electronic equipment in a charging state and the electronic equipment in a discharging state through shielding information in the posture information of the first electronic equipment, and can control the first electronic equipment to output the first electric energy to the second electronic equipment or control the first electronic equipment to receive the second electric energy output by the second electronic equipment by adjusting the placing mode between the first electronic equipment and the second electronic equipment according to the own requirements of the user. Therefore, the user can independently adjust whether the electronic equipment is in a charging state or a discharging state, and the use experience of the user is improved.
To make the use more convenient for the user, please continue to refer to the electric energy relay device shown in fig. 2.
The power transfer device is further configured with a first switch 270 matched with the first interface 230, a second switch 290 matched with the second interface 250, and a third switch 280 matched with the electromagnetic induction coil 220.
The first switch 270 is used to control the first interface 230 to be in a charging state or to control the first interface 230 to be in a discharging state. The second switch 290 is used to control the second interface 250 to be in a charging state or to control the second interface 250 to be in a discharging state. The third switch 280 can control the electromagnetic coil 220 to generate an electromagnetic field or an induced magnetic field.
For example, the state control signal sent by the first switch 270 to the power management chip may be represented by "0" and "1", and when the power management chip 210 receives the state control signal of the first switch 270, the state control signal is "0", the first interface 230 is controlled to be in the charging state, and when the state control signal of the first switch 270 is "1", the state control signal is received, the first interface 230 is controlled to be in the discharging state.
Similarly, the state control signal sent by the second switch 290 to the power management chip may be represented by "0" and "1", and when the power management chip 210 receives the state control signal of the second switch 290 as "0", the second interface 250 is controlled to be in the charging state, and when the state control signal of the second switch 290 is received as "1", the second interface 250 is controlled to be in the discharging state.
The state control signal sent by the third switch 280 to the power management chip can also be represented by "0" and "1". When the power management chip 210 receives a control command of "0" from the third switch 280, the electromagnetic induction coil 220 is controlled to be in the magnetic field releasing state, and when the power management chip 210 receives a control command of "1" from the third switch 280, the electromagnetic induction coil 220 is controlled to be in the magnetic field inducing state.
In the embodiment of the invention, a user can control the first interface to be in the charging state by using the first switch or control the first interface to be in the discharging state by using the first switch, so that the user can accurately know the charging and discharging states of the first electronic device connected with the first interface, and can also control the magnetic field state of the electromagnetic induction coil by using the third switch, and the electronic device on the charging side and the electronic device on the discharging side can be accurately judged by using the magnetic field state of the electromagnetic induction coil, thereby improving the use experience of the user.
In some embodiments of the present invention, in order to better determine the charging state of the electronic device, the present invention further provides another charging method, and fig. 8 is a flowchart of the charging method according to another embodiment of the present invention. As shown in fig. 8, the method includes:

The first switch 270, the second switch 290, and the third switch 280 may be key switches, and a user may transmit the state control signal to the first electronic device and the second electronic device by pressing the key switches.
For example, when the first switch 270 is pressed, a discharge control signal is transmitted to the first electronic device, and when the first switch is in the pop-up state, a charge control signal is transmitted to the first electronic device. When the third switch 280 is pressed, a discharge control signal is transmitted to the second electronic device, and when the second switch is in the pop-up state, a charge control signal is transmitted to the second electronic device.
Then, when the state control signal received by the first electronic device is a discharging control signal, the first electronic device will be used as a first target device, and when the state control signal received by the second electronic device is a charging control signal, the second electronic device will be used as a second target device.
