[0044] In order to solve the current problem, the present application provides a magnetic wireless charging device, which includes:

[0045] The first magnetic component is used to absorb and fix the charged device placed on the surface of the magnetic wireless charging device;

[0046] A driving device, used for driving the first magnetic component to move between a first position and a second position, wherein when the first magnetic component is located at the first position, the first magnetic component can adsorb and fix a charged device placed on the surface of the magnetic wireless charging device, and when the first magnetic component is located at the second position, the first magnetic component deviates from a second magnetic component of the charged device placed on the surface of the magnetic wireless charging device;

[0047] The controller is used to: when the charged device placed on the surface of the magnetic wireless charging device leaves the surface of the magnetic wireless charging device, control the driving device to drive the first magnetic component to move from the first position to the second position; when the charged device has moved away from the magnetic wireless charging device or the charged device is placed on the surface of the magnetic wireless charging device but is not in a working state, control the driving device to drive the first magnetic component to move from the second position to the first position.

[0048] The magnetic wireless charging device of the present application includes a first magnetic component, a driving device and a controller. When the charged device placed on the surface of the magnetic wireless charging device leaves the surface of the magnetic wireless charging device, the driving device is controlled by the controller to drive the first magnetic component to move from the first position to the second position to weaken or eliminate the force between the first magnetic component and the second magnetic component, so that the user can remove the first magnetic component placed on the surface of the magnetic wireless charging device without spending too much effort, thereby improving the user's experience. When the charged device is far away from the magnetic wireless charging device, the driving device is controlled by the controller to drive the first magnetic component to move from the second position to the first position, so that when the user uses the magnetic wireless charging device next time, the first magnetic component can be ensured to absorb and position the charged device, thereby charging the charged device, and will not affect the normal realization of the charging function of the magnetic wireless charging device. In addition, when the charged device is placed on the surface of the magnetic wireless charging device and is not in a working state, the first magnetic component is driven by the driving device to move from the second position to the first position to reset, thereby ensuring the normal realization of the charging function.

[0049] Below, reference Figure 1 The magnetic wireless charging device of the present application is explained and illustrated. Figure 1 is a schematic block diagram of a magnetic wireless charging device in an embodiment of the present application; Figure 2 is a schematic block diagram of a driving device in an embodiment of the present application.

[0050] As an example, Figure 1 As shown, the magnetic wireless charging device 100 of the present application includes a housing (not shown), and the housing has a containing space. The shape of the housing can be reasonably set according to actual needs, for example, it can be square, circular, elliptical, polygonal or other irregular shapes.

[0051] The shell is usually made of insulating materials, including but not limited to plastics, such as ABS plastic, PC and other materials. The use of these materials with good insulation and flame retardancy can increase the flame retardant temperature of the shell and further enhance the safety of the shell. Of course, it is not limited to the above materials, for example, it can also be made of metal materials.

[0052] The housing has a containing space therein, and the containing space is used to accommodate, for example, a battery cell, a driving device, a coil, a controller 101, a first magnetic component 104, and the like.

[0053] In one example, the magnetic wireless charging device 100 further includes a battery cell (not shown), which may be any battery cell capable of storing electrical energy known to those skilled in the art, such as a lithium-ion battery cell, etc., which may have charging and discharging functions.

[0054] In one example, the magnetic wireless charging device 100 further includes a coil (not shown), which is used to enable the magnetic wireless charging device to charge the charged device, and wirelessly charge the charged device such as a mobile phone, a tablet computer, etc. through the coil. For example, the coil is used to charge the charged device through electromagnetic coupling with a receiving coil of a charged device such as a mobile phone, and the charged device includes but is not limited to a mobile phone, a tablet computer, etc. The coil can be made of a material with good electrical conductivity such as copper or aluminum. Exemplarily, the coil can be in a ring structure.

[0055] In one example, the magnetic wireless charging device 100 also includes a first magnetic component 104, which is used to adsorb and fix the charged device placed on the surface of the magnetic wireless charging device. Optionally, the first magnetic component 104 is arranged in the accommodating space of the shell and is located on the outside of the coil, so as to avoid the magnetic field of the first magnetic component from interfering with the magnetic field of the coil. The first magnetic component 104 is used to make the position of the coil for receiving electric energy of the charged device correspond to the position of the coil of the magnetic wireless charging device, and can also play the role of fixing the charged device.

[0056] Exemplarily, the first magnetic component 104 is annular or partially annular and is arranged outside the coil 104. Optionally, the first magnetic component 104 may include one or more magnets, such as an annular magnet, or multiple magnets arranged at intervals, or multiple magnets connected end to end.

[0057] In one example, the magnetic wireless charging device 100 of the present application also includes a driving device 102, which is used to drive the first magnetic component 104 to move between a first position and a second position, wherein when the first magnetic component 104 is located at the first position, the first magnetic component 104 can adsorb and fix the charged device placed on the surface of the magnetic wireless charging device, that is, the first magnetic component 104 located at the first position is used to make the position of the coil for receiving electrical energy of the charged device correspond to the position of the coil of the magnetic wireless charging device, and can also play a role in fixing the charged device. When the first magnetic component 104 is located at the first position, the first magnetic component 104 surrounds the coil in a ring shape or a partial ring shape.

[0058] Optionally, when the first magnetic component 104 is located at the second position, the first magnetic component 104 deviates from the second magnetic component of the charged device placed on the surface of the magnetic wireless charging device, that is, when the first magnetic component 104 is located at the second position, the first magnetic component 104 deviates from the second magnetic component of the charged device, thereby weakening the force of the first magnetic component 104 on the charged device, that is, the attraction. The second position can be any suitable position in the shell that can meet the above-mentioned action requirements, or it can also be located outside the shell.

[0059] Continue as Figure 1 As shown, the magnetic wireless charging device of the present application also includes a controller 101, which is used to: when the charged device placed on the surface of the magnetic wireless charging device leaves the surface of the magnetic wireless charging device, control the driving device 102 to drive the first magnetic component 104 to move from the first position to the second position, and when the charged device is away from the magnetic wireless charging device, control the driving device 102 to drive the first magnetic component 104 to move from the second position to the first position for reset. The controller 101 can be any suitable controller 101 known to those skilled in the art, for example, it can include a microcontroller unit (MCU).

[0060] When the charged device placed on the surface of the magnetic wireless charging device leaves the surface of the magnetic wireless charging device, the controller 101 controls the driving device 102 to drive the first magnetic component 104 to move from the first position to the second position, so as to weaken or eliminate the force between the first magnetic component 104 and the second magnetic component, so that the user can easily remove the first magnetic component 104 placed on the surface of the magnetic wireless charging device without expending too much effort, thereby improving the user's usage experience, and when the charged device is away from the magnetic wireless charging device, the controller 101 controls the driving device 102 to drive the first magnetic component 104 to move from the second position to the first position, so that the next time the user uses the magnetic wireless charging device, it can ensure that the first magnetic component 104 adsorbs and positions the charged device, thereby charging the charged device, and will not affect the normal implementation of the charging function of the magnetic wireless charging device.

[0061] Optionally, the controller 101 is also used to: when the charged device is placed on the surface of the magnetic wireless charging device but is not in a working state, control the drive device 102 to drive the first magnetic component 104 to move from the second position to the first position. Since when the charged device is placed on the surface of the magnetic wireless charging device but is not in a working state, it indicates that the magnetic wireless charging device cannot charge the charged device, and the first magnetic component 104 may be misplaced, therefore, control the drive device 102 to drive the first magnetic component 104 to move from the second position to the first position to reset the magnetic component, thereby ensuring the normal implementation of the charging function.

[0062] In one example, if Figure 1 As shown, the magnetic wireless charging device also includes a detection unit 103, which is used to detect whether the user touches the magnetic wireless charging device. When it is detected that the user touches the magnetic wireless charging device, a detection signal is output, and the detection signal is used to indicate that the charged device placed on the surface of the magnetic wireless charging device is leaving the surface of the magnetic wireless charging device or the charged device is placed on the magnetic wireless charging device. The detection signal output by the detection unit 103 triggers the controller 101 to control the driving device 102.

[0063] Optionally, the detection unit 103 may include a touch chip arranged in the shell. When the user takes away the charged device placed in the magnetic wireless charging device or places the charged device in the magnetic wireless charging device, the hand will touch the touch chip. When the touch chip detects that the user touches the magnetic wireless charging device, it outputs a detection signal.

[0064] Optionally, the detection unit 103 is communicatively connected to the controller 101, and the controller 101 is used to: when a detection signal is obtained and the magnetic wireless charging device is in a working state, control the driving device 102 to drive the first magnetic component 104 to move from the first position to the second position. When the detection signal is obtained and the magnetic wireless charging device is in a working state, it indicates that the user wants to take away the charged device. Therefore, the controller 101 controls the driving device 102 to drive the first magnetic component 104 to move from the first position to the second position to weaken or eliminate the force between the first magnetic component 104 and the second magnetic component, so that the user does not need to expend too much effort to remove the first magnetic component 104 placed on the surface of the magnetic wireless charging device, thereby improving the user's experience.

[0065] Optionally, when the detection signal is not obtained and the magnetic wireless charging device is not in a working state, the control drive device 102 drives the first magnetic component 104 to move from the second position to the first position. When the detection signal is not obtained and the magnetic wireless charging device is not in a working state, it indicates that the user has taken away the charged device, or that there is no charged device on the surface of the magnetic wireless charging device. Therefore, the first magnetic component 104 can be reset, that is, the control drive device 102 drives the first magnetic component 104 to move from the second position to the first position, so that the next time the user uses the magnetic wireless charging device, it can ensure that the first magnetic component 104 adsorbs and positions the charged device, thereby charging the charged device, and will not affect the normal implementation of the charging function of the magnetic wireless charging device.

[0066] Optionally, when a detection signal is obtained and the magnetic wireless charging device is not in a working state, the control drive device 102 drives the first magnetic component 104 to move from the second position to the first position. When a detection signal is obtained and the magnetic wireless charging device is not in a working state, it indicates that the magnetic wireless charging device cannot charge the charged device, and the first magnetic component 104 may be misplaced. Therefore, the control drive device 102 drives the first magnetic component 104 to move from the second position to the first position to reset the magnetic component, thereby ensuring the normal implementation of the charging function.

[0067] In one example, if Figure 2 As shown, the driving device 102 includes a driving circuit 1021 and a motor 1022. The driving circuit 1021 is electrically connected to the controller 101 and the motor. The driving circuit is used to: obtain a control signal output by the controller 101, and control the motor to drive the first magnetic component to move according to the control signal. The controller 101 can output a first control signal when a detection signal is obtained and the magnetic wireless charging device is in a working state, and output a second control signal when the detection signal is not obtained or the detection signal is obtained and the magnetic wireless charging device is not in a working state, thereby controlling the driving device to perform different actions.

[0068] Optionally, the control signal includes a first control signal and a second control signal. When the control signal is the first control signal, the drive circuit is used to: control the motor to drive the first magnetic component 104 to move from the first position to the second position according to the first control signal. For example, the motor and the first magnetic component 104 are connected through a rotating shaft. The motor is controlled to drive the rotating shaft to rotate counterclockwise according to the first control signal, and the rotating shaft drives the first magnetic component 104 to move from the first position to the second position, thereby ultimately causing the first magnetic component 104 to deviate from the first position; when the control signal is the second control signal, the drive circuit is used to: control the motor to drive the first magnetic component 104 to move from the first position to the second position according to the second control signal. The signal controls the motor to drive the first magnetic component 104 to move from the second position to the first position. For example, when the user has taken away the charged device, the controller 101 detects whether the detection signal output by the detection unit 103 can still be obtained. If there is no detection signal and the output is a second detection signal, the controller 101 outputs a second control signal, and the drive circuit is used to control the motor to drive the first magnetic component 104 to move from the second position to the first position according to the second control signal. For example, the motor rotates forward, thereby resetting the first magnetic component 104 to the first position, preparing for the next time the user places the charged device for charging.

[0069] Optionally, when the detection unit 103 outputs a detection signal, when the controller 101, such as the MCU, obtains the detection signal, the MCU begins to determine whether the magnetic wireless charging device is working. If the magnetic wireless charging device is not working, the motor is controlled to rotate forward and the first magnetic component 104 is driven to reset to ensure the normal operation of the magnetic wireless charging.

[0070] In one example, the controller 101 is also used to: obtain motion data information of the drive device 102; based on the motion data information, determine whether the first magnetic component 104 moves from the first position to the second position, or determine whether the first magnetic component 104 moves from the second position to the first position, wherein when it is determined according to the motion data information that the drive device 102 has moved to the second position or has moved to the first position, the drive device 102 is controlled to stop working.

[0071] Optionally, the motion data information includes the number of rotations of the motor, or may also include motion data information such as direction and speed. After the controller 101 obtains the number of rotations of the motor, the moving distance of the first magnetic component 104 can be calculated based on the number of rotations of the motor, and the moving distance can be compared with the preset distance between the first position and the second position to determine whether it has moved into place, thereby further controlling the drive device 102 to stop working, for example, controlling the motor to stop rotating.

[0072] In one example, the magnetic wireless charging device includes a first limiting structure and a second limiting structure, wherein the first limiting structure is used to limit the first magnetic component 104 moved from the first position to the second position to the second position, and the second limiting structure is used to limit the first magnetic component 104 moved from the second position to the first position to the first position. The first limiting structure and the second limiting structure can accurately locate the position to which the first magnetic component 104 needs to be moved, thereby ensuring the realization of its function. Optionally, the first limiting structure and the second limiting structure can be structures such as limiting blocks.

[0073] In one example, the controller 101 is also used to: detect the current output by the drive circuit; determine whether the first magnetic component 104 has moved to the first position or the second position according to the current, wherein when the current is greater than the preset current, it is determined that the first magnetic component 104 has moved to the first position or the second position. For example, when the first magnetic component 104 reaches the first limit structure or the second limit structure under the drive of, for example, a motor, the first magnetic component 104 is restricted from moving, so that the motor can no longer rotate, which will cause the drive circuit to output a larger current, thereby judging whether the first magnetic component 104 has moved to the predetermined position based on the magnitude of the current, so that the controller 101 can more accurately control the drive device 102 to stop working, such as controlling the motor to stop rotating, when the first magnetic component 104 moves to the predetermined position.

[0074] The magnetic wireless charging device 100 also includes a circuit board, on which are integrated components for realizing the corresponding functions of the magnetic wireless charging device (such as a wireless charging power supply), for example, components with functions related to transmission to realize corresponding power supply and other functions (such as signal processing and other functions). The controller 101 can be set on the circuit board.

[0075] Optionally, a power input interface and a power output interface (not shown) are provided on the side of the housing of the magnetic wireless charging device 100. The power input interface is used to charge the battery cell of the magnetic wireless charging device 100 through an external circuit, and the power output interface is used to supply power to an external circuit (such as an electronic device such as a mobile phone, a tablet computer, a headset, etc.). The side of the housing may also include a button for adjusting the output power, an indicator light for displaying the remaining power of the magnetic wireless charging device, and other elements that can be selected and set by those skilled in the art as needed, which will not be described in detail here.

[0076] So far, the description of the magnetic wireless charging device of the present application has been completed. A complete magnetic wireless charging device may also include other components, which will not be described one by one here.

[0077] In summary, in order to facilitate users to remove the charged device from the magnetic wireless charging device, the present application provides a magnetic wireless charging device, which includes a first magnetic component, a driving device and a controller. When the charged device placed on the surface of the magnetic wireless charging device leaves the surface of the magnetic wireless charging device, the controller controls the driving device to drive the first magnetic component to move from the first position to the second position, so as to weaken or eliminate the force between the first magnetic component and the second magnetic component, so that the user does not need to expend too much effort to remove the first magnetic component placed on the surface of the magnetic wireless charging device, thereby improving the user's usage experience.
