Description

Technical Field

[0001] The present application relates to the field of wireless charging technology, and particularly to a wireless charging device, a charging method thereof, and an electronic device. Background Art

[0002] In recent years, with the continuous development of technology, various terminal devices have gradually emerged in people's daily lives and have become an indispensable part of modern people's daily lives. The traditional charging method is that different terminal devices rely on charging cables matching them for charging, and this wired charging method is rather troublesome and cannot meet the charging needs of modern people. Therefore, wireless charging devices have emerged as the times require.

[0003] However, the current wireless charging devices still require manual operation, which easily causes the detachment of structural components and leads to the abnormal use of the wireless charging device. Summary of the Invention

[0004] Embodiments of the present application provide a wireless charging device, a charging method thereof, and an electronic device to solve or alleviate one or more technical problems in the prior art.

[0005] As the first aspect of the embodiments of the present disclosure, embodiments of the present disclosure provide a wireless charging device, including a receiving bin, a wireless charging module, a control module, and a driving component, where the wireless charging module is connected to the control module;

[0006] The control module is configured to send a first control signal to the driving component when it detects that the change in magnetic flux of the wireless charging module meets a preset condition in the first state, and the first state is the state where the wireless charging module is located inside the receiving bin;

[0007] The driving component is configured to drive the wireless charging module to convert from the first state to the second state to charge the terminal device under the control of the first control signal, and the second state is the state where the wireless charging module is located outside the receiving bin.

[0008] In one implementation, the control module is further configured to send a second control signal to the driving component when it detects that the change in magnetic flux of the wireless charging module does not meet the preset condition in the second state;

[0009] The driving component is further configured to drive the wireless charging module to reset from the second state to the first state under the control of the second control signal.

[0010] In one implementation, the driving component includes a power source, a winding, and a self-locking mechanism. The winding is wound around the power shaft of the power source, the movable end of the winding is connected to the wireless charging module, and the wireless charging module is connected to the self-locking mechanism;

[0011] Under the control of the first control signal, the power shaft of the power source rotates and winds the wire, so as to apply a first pulling force with a preset duration to the wireless charging module through the winding of the wire.

[0012] The self-locking mechanism is configured to be converted from the first locking state to the second locking state after the wireless charging module bears the first pulling force for a preset duration, so that the wireless charging module extends out of the accommodation bin to the second state and remains.

[0013] In an implementation manner, when the power source is under the second control signal, the power shaft of the power source rotates and winds up the wire, so as to apply a second pulling force to the wireless charging module through the winding of the wire, driving the wireless charging module to reset from the second state to the first state. The self-locking mechanism is converted from the second locking state to the first locking state along with the reset of the wireless charging module, and the wireless charging module is kept in the first state.

[0014] In an implementation manner, the wireless charging device further includes a support plate located in the accommodation bin. The support plate includes a first end and a second end arranged oppositely. The first end is close to the outside of the accommodation bin. The support plate further includes a slideway arranged between the first end and the second end.

[0015] The self-locking mechanism includes a locking block, a locking member and an elastic member. The locking block is slidably arranged in the slideway. One end of the elastic member is connected to one of the first end and the second end, and the other end of the elastic member is connected to the locking block. The locking block is provided with a locking position, an extending position and a first track arranged between the locking position and the extending position. One end of the locking member is rotatably connected to the second end.

[0016] Applying the first pulling force with a preset duration to the wireless charging module through the winding of the wire causes the other end of the locking member to pop out from the locking position. The locking block moves towards the first end direction under the reset action of the elastic member, so that the other end of the locking member moves along the first track to the extending position, and the wireless charging module is converted from the first state to the second state along with the movement of the locking block.

[0017] In an implementation manner, the locking block is further provided with a second track arranged between the locking position and the extending position. Applying the second pulling force to the wireless charging module through the winding of the wire drives the wireless charging module to move from the second state towards the inside of the accommodation bin to the first state. The locking block forces the other end of the locking member to move from the extending position to the locking position along the second track along with the movement of the wireless charging module, and locks the locking block, so that the wireless charging module is locked in the first state.

[0018] In an implementation manner, the elastic member is a stretchable spring, and the stretchable spring is located between the first end and the locking block.

[0019] In an implementation manner, the driving assembly further includes a wire winding disc located between the wireless charging module and the power source, and the wire is wound on the wire winding disc.

[0020] In one embodiment, the wireless charging module includes a carrier and a charging coil disposed on the carrier. The carrier is connected to a driving component. The control module is further configured to control the charging coil to charge the terminal device when it detects that the terminal device is placed on the carrier.

[0021] In one embodiment, the control module includes a detection unit and a controller. The detection unit is connected to the wireless charging module;

[0022] The detection unit is configured to send a start signal to the controller when it detects that the change in magnetic flux of the wireless charging module meets a preset condition in a first state; the controller is configured to send a first control signal to the driving component when it receives the start signal;

[0023] The detection unit is further configured to send a stop signal to the controller when it detects that the change in magnetic flux of the wireless charging module does not meet the preset condition in a second state; the controller is further configured to send a second control signal to the driving component when it receives the stop signal.

[0024] In one embodiment, the preset conditions include: the change in magnetic flux is greater than or equal to a preset value; the duration of the change in magnetic flux is greater than or equal to a preset duration.

[0025] As a second aspect of the embodiments of the present disclosure, the embodiments of the present disclosure provide a charging method for a wireless charging device, which is used for the wireless charging device in the embodiments of the present disclosure. The method includes:

[0026] When the control module detects that the change in magnetic flux of the wireless charging module meets the preset condition in a first state, it sends a first control signal to the driving component. The first state is the state where the wireless charging module is located in the accommodation bin;

[0027] Under the control of the first control signal, the driving component drives the wireless charging module to switch from the first state to the second state to charge the terminal device. The second state is the state where the wireless charging module is located outside the accommodation bin.

[0028] In one embodiment, it further includes:

[0029] When the control module detects that the change in magnetic flux of the wireless charging module does not meet the preset condition in the second state, it sends a second control signal to the driving component;

[0030] Under the control of the second control signal, the driving component drives the wireless charging module to reset from the second state to the first state.

[0031] As a third aspect of the embodiments of the present disclosure, the embodiments of the present disclosure provide an electronic device, which includes the wireless charging device in the embodiments of the present disclosure.

[0032] The wireless charging device according to the embodiment of the present application adopts the above technical solution, and cleverly uses the change of magnetic flux to automatically control the wireless charging module to pop out from the accommodation bin, without manual operation, which is beneficial to improving the loosening of internal structural parts caused by manual operation, and at the same time can also reduce the cost of replacing structural parts.

[0051] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0052] In the related art, most wireless charging modules are based inside the whole machine and cannot be externalized. The built-in wireless charging module has defects in terms of temperature and user experience. During the charging process, the built-in wireless charging module causes the temperature of the whole machine to rise, which is not conducive to the operation of the whole machine. Some wireless charging modules that can be externalized require manual operation by the user. For example, the user needs to manually press a button to make the wireless charging module extend from inside the whole machine. Long-term manual operation will cause the detachment of structural parts, resulting in loosening of the matching of structural components, and ultimately the wireless charging module cannot be used normally.

[0053] In the related art, a first charging coil 20 is provided on the charging board 10 of the wireless charging device, and the first charging coil 20 generates a magnetic field with a specific law different from other natural magnetic fields. When the terminal device to be charged is placed above the charging board 10, such as Figure 1As shown, the magnetic field intensity generated by the first charging coil 20 will change due to the terminal device to be charged. Therefore, it is possible to determine whether there is a terminal device to be charged based on the change in the magnetic field of the first charging coil 20. An embodiment of the present disclosure provides a wireless charging device that can cleverly control the wireless charging module to pop out or retract from the accommodation bin according to the change value of the magnetic field intensity.

[0054] Please refer to Figures 2 to 8 together. The wireless charging device includes an accommodation bin (not shown), a wireless charging module 30, a control module (not shown), and a driving component 40.

[0055] Specifically, the wireless charging module 30 is connected to the control module; the control module is configured to send a first control signal to the driving component 40 when it detects that the magnetic flux change of the wireless charging module 30 satisfies a preset condition in the first state; the driving component 40 is configured to drive the wireless charging module 30 to switch from the first state to the second state to charge the terminal device under the control of the first control signal. Here, the first state is the state where the wireless charging module 30 is located inside the accommodation bin, and the second state is the state where the wireless charging module 30 is located outside the accommodation bin.

[0056] In this embodiment, the wireless charging module 30 is housed in the accommodation bin. Then, the terminal device to be charged is placed above the wireless charging module 30, so that the control module can detect the change in the magnetic flux of the wireless charging module 30 and compare the detected result with the preset condition. If the preset condition is satisfied, a first control signal is sent to the driving component 40, so that the driving component 40 drives the wireless charging module 30 to pop out from the accommodation bin to the outside of the accommodation bin under the control of the first control signal. Then, the terminal device to be charged is placed on the wireless charging module 30 for charging. By cleverly using the change in magnetic flux, the wireless charging module can be automatically controlled to pop out from the accommodation bin without manual operation, which is beneficial to improving the loosening of internal structural parts caused by manual operation and can also reduce the cost of replacing structural parts.

[0057] It should be noted that the magnetic flux change is defined as the difference between the current magnetic flux of the wireless charging module and the first magnetic flux. Assume that the self-magnetic flux of the wireless charging module 30 is the first magnetic flux. When a terminal device approaches, the current magnetic flux of the wireless charging module 30 is the second magnetic flux, and the difference between the second magnetic flux and the first magnetic flux is the magnetic flux change value.

[0058] Exemplarily, the preset conditions may include that the magnetic flux change reaches a preset value, and / or the duration for which the magnetic flux change persists reaches a preset time. For example, when the battery power of the terminal device is high, after the terminal device approaches the wireless charging module 30, the control module detects that the magnetic flux change of the wireless charging module 30 does not reach the preset value, that is, the preset conditions are not met, indicating that the terminal device does not need to be charged. For example, when the user accidentally approaches the terminal device to the wireless charging module 30, the control module detects that the duration for which the magnetic flux change of the wireless charging module 30 persists is too short and does not reach the preset time, that is, the preset conditions are not met, indicating that the terminal device does not need to be charged. In both of these cases, the wireless charging module 30 remains in the first state. By setting the preset conditions, the misoperation of the wireless charging device can be avoided.

[0059] Exemplarily, the control module and the driving component 40 are located in the accommodation bin. This is beneficial for protecting the control module and the driving component 40 and can prevent interference or damage from external substances.

[0060] In one implementation, the control module is further configured to send a second control signal to the driving component 40 when it detects that the magnetic flux change of the wireless charging module 30 does not meet the preset conditions in the second state. The driving component 40 is further configured to drive the wireless charging module 30 to reset from the second state to the first state under the control of the second control signal.

[0061] Exemplarily, during the charging process, the magnetic flux of the wireless charging module 30 changes with the change in the battery level of the terminal device. When the terminal device is removed from the wireless charging module 30, the wireless charging module 30 stops charging. After the charging is completed, if the control module detects that the magnetic flux change of the wireless charging module 30 does not meet the preset conditions, it sends a second control signal to the driving component 40 so that the driving component 40 is controlled to drive the wireless charging module 30 to reset from the second state to the first state (i.e., from the wireless charging module being outside the accommodation bin to inside the accommodation bin). The wireless charging device according to the embodiments of the present disclosure cleverly uses the change in magnetic flux to control the automatic retraction of the wireless charging module 30 into the accommodation bin without manual operation, which is beneficial for improving the loosening of internal structural components caused by manual operation and can also reduce the cost of replacing structural components.

[0062] In one implementation, the driving component 40 includes a power source 41, a winding 42, and a self-locking mechanism 43. The winding 42 is wound around the power shaft of the power source 41. The movable end of the winding 42 is connected to the wireless charging module 30, and the wireless charging module 30 is connected to the self-locking mechanism 43.

[0063] Under the control of the first control signal, the power shaft of the power source 41 rotates to wind up the winding 42, so as to apply a first pulling force with a preset duration to the wireless charging module 30 through the winding 42. The self-locking mechanism 43 is configured to be switched from the first locked state to the second locked state after the wireless charging module 30 bears the first pulling force for the preset duration, so that the wireless charging module 30 extends out of the accommodation bin to the second state and remains.

[0064] Exemplarily, in the case of the second control signal, the power shaft of the power source 41 rotates to retract the winding 42, so as to apply a second pulling force to the wireless charging module 30 through the winding 42, driving the wireless charging module 30 to reset from the second state to the first state. The self-locking mechanism 43 is switched from the second locked state to the first locked state along with the reset of the wireless charging module 30, and the wireless charging module 30 is kept in the first state.

[0065] In this embodiment, the first locked state means that when the wireless charging module 30 is received in the accommodation bin, the self-locking mechanism 43 locks the wireless charging module 30, so that the wireless charging module 30 remains in the first state; while the second locked state means that when the wireless charging module 30 pops out of the accommodation bin, the self-locking mechanism 43 locks the wireless charging module, so that the wireless charging module 30 remains in the second state.

[0066] Adopting the above structure can automatically control the wireless charging module 30 to pop out of the accommodation bin or be received back into the accommodation bin without manual operation, which is beneficial to improving the loosening of internal structural parts caused by manual operation.

[0067] It should be noted that the self-locking mechanism 43 can achieve self-locking of the state. The duration of the first pulling force is relatively short. For example, a short-term first pulling force is applied to the wireless charging module 30, so that after the self-locking mechanism 43 disengages from the first self-locked state, the self-locking mechanism 43 can pop the wireless charging module 30 out of the accommodation bin to the second state under the action of its own structure, and the self-locking mechanism 43 is switched to the second locked state, so that the wireless charging module 30 remains in the second state.

[0068] Exemplarily, the duration of the second pulling force is greater than the duration of the first pulling force.

[0069] In one embodiment, as Figure 3 and Figure 4 shown, the wireless charging device further includes a support plate 50. The support plate 50 is located in the accommodation bin. The support plate 50 includes a first end 50B and a second end 50A arranged oppositely, and the first end 50B is close to the outside of the accommodation bin. The support plate 50 further includes a slideway 50C arranged between the first end 50B and the second end 50A.

[0070] As Figures 4 to 6As shown, the self-locking mechanism 43 includes a locking block 432, a locking member 433, and an elastic member 431. The locking block 432 is slidably disposed within the slideway 50C. One end of the elastic member 431 is connected to one of the first end 50B and the second end 50A, and the other end of the elastic member 431 is connected to the locking block 432. The locking block 432 is provided with a locking position 438, an extended position 439, and a first track 434 disposed between the locking position 438 and the extended position 439. One end of the locking member 433 is rotatably connected to the second end 50A.

[0071] Exemplarily, the winding 42 applies a first pulling force of a preset duration to the wireless charging module 30 such that the other end of the locking member 433 pops out from the locking position 438. The locking block 432 moves in the direction of the first end 50B under the reset action of the elastic member 431, such that the other end of the locking member 433 moves along the first track 434 to the extended position 439, and the wireless charging module 30 is converted from the first state to the second state as the locking block 432 moves.

[0072] In one embodiment, the locking block 432 is further provided with a second track 435 disposed between the locking position 438 and the extended position 439. The winding 42 applies a second pulling force to the wireless charging module 30 to drive the wireless charging module 30 to move from the second state towards the inside of the receiving bin to the first state. The locking block 432 forces the other end of the locking member 433 to move along the second track 435 from the extended position 439 to the locking position 438 as the wireless charging module 30 moves, and locks the locking block 432, such that the wireless charging module 30 is locked in the first state.

[0073] Exemplarily, as Figures 4 to 6 shown, the locking block 432 may be provided with a sunken groove. Both the locking position 438 and the extended position 439 are located within the groove. A convex block 436 and a guiding block 437 are disposed between the locking position 438 and the extended position 439. The guiding block 437 is located on the side of the convex block 436 facing the elastic member 431. The convex block 436 is generally triangular, and one side edge of the convex block 436 facing the guiding block 437 is a concave edge, and one side edge of the guiding block 437 facing the convex block 436 is a convex edge, as Figure 5 shown. The locking position 438 is located between the guiding block 437 and the convex block 436. The upper part of the convex block 436 forms a first track 434 between the guiding block 437 and the side of the locking block 432, as Figure 6 shown, and the first track 434 is shown by a thick solid line in Figure 6 . The lower part of the convex block 436 forms a second track 435 between the guiding block 437 and the side of the locking block 432, as Figure 6 shown, and the second track 435 is shown by a thick solid line in Figure 6 . And an arc-shaped groove (not shown) is provided at one end of the convex block 436 facing the guiding block 437.

[0074] As Figure 5 and Figure 6 shown, at the position of the extended position 439, the second track 435 includes a guiding section 4351 near the extended position 439. Exemplarily, the guiding section 4351 is recessed relative to the first track 434. Thus, during the process that the end of the locking member 433 moves from the extended position 439 through the second track 435 to the locking position 438, the end of the locking member 433 can move along the second track 435 under the guiding action of the guiding section 4351, avoiding the end of the locking member 433 sliding onto the first track 434.

[0075] Referring Figures 4 to 6 , when the wireless charging module 30 is in the first state, a short-term first pulling force is applied to the wireless charging module 30, so that the end of the locking member 433 pops out from the locking position 438. Under the elastic reset action of the elastic member 431, the locking block 432 moves towards the direction of the elastic member 431, so that the end of the locking member 433 moves along the first track 434 to the extended position 439 and is held at the extended position 439 under the action of the elastic member 431. During this process, the wireless charging module 30 pops out to the second state along with the movement of the locking block 432 and remains.

[0076] Referring Figures 4 to 6 , when the wireless charging module 30 is driven by a second pulling force to drive the locking block 432 to move away from the elastic member 431, under the guiding action of the guiding section 4351, the end of the locking member 433 enters the second track 435 along the guiding section 4351, moves along the second track 435 to the locking position 438, and is locked at the locking position 438, thereby locking the wireless charging module 30 and receiving the wireless charging module 30 into the accommodation bin.

[0077] In one embodiment, the elastic member 431 is a stretchable spring, and the stretchable spring is located between the first end and the locking block 432. Exemplarily, the elastic member 431 is a stretchable spring. When the wireless charging module 30 is driven by the power source 41, the locking member 433 and the locking block 432 are disengaged from each other, and then the elastic force of the stretchable spring is used to enable the wireless charging module 30 to automatically pop out from the accommodation bin, thereby realizing the automatic control of the wireless charging module 30. In addition, the elastic member 431 can be other elastic components (such as rubber bands, circlips, etc.) in addition to being a stretchable spring.

[0078] In the above embodiment, the elastic member 431 is located between the first end 50B and the locking block 432. In other embodiments, the elastic member can be arranged between the second end 50A and the locking block 432. Correspondingly, the elastic member can be a compressible elastic member, such as a compressible spring.

[0079] In one embodiment, the driving component 40 further includes a winding disk 44, which is located between the wireless charging module 30 and the power source 41, and the winding 42 is wound around the winding disk 44. It should be noted that by arranging the winding disk 44 between the wireless charging module 30 and the power source 41 and winding the winding 42 around the winding disk 44, when the power source 41 pulls the winding 42, the winding disk 44 can be driven to rotate, so as to realize the storage of part of the winding 42, and prevent the winding 42 from being randomly wound around other components in the accommodation bin, which may affect the automatic control of the pop-up or retraction of the wireless charging module 30.

[0080] In one embodiment, the wireless charging module 30 includes a carrier 31 and a charging coil 32 disposed on the carrier 31. The carrier 31 is connected to the driving component 40. The control module is further configured to control the charging coil 32 to charge the terminal device when it detects that the terminal device is placed on the carrier 31.

[0081] Exemplarily, when the driving component 40 ejects the carrier 31 from the accommodation bin and the control module detects that the terminal device is placed on the carrier 31, the control module controls the charging coil 32 to start charging the terminal device; if the control module does not detect that the terminal device is placed on the carrier 31, the control module does not control the charging coil 32 to charge the terminal device, realizing the intelligent control of the charging coil 32, which helps to protect the battery of the terminal device and can prevent the battery from being damaged due to unstable current.

[0082] In one embodiment, the control module includes a detection unit and a controller, and the detection unit is connected to the wireless charging module.

[0083] Among them, the detection unit is configured to send a start signal to the controller when it detects that the magnetic flux change of the wireless charging module 30 satisfies a preset condition in the first state. The controller is configured to send a first control signal to the driving component 40 when it receives the start signal.

[0084] The detection unit is further configured to send a stop signal to the controller when it detects that the magnetic flux change of the wireless charging module 30 does not satisfy the preset condition in the second state. The controller is further configured to send a second control signal to the driving component 40 when it receives the stop signal.

[0085] In this embodiment, the detection unit in the control module is used to detect the magnetic flux change of the wireless charging module 30, then compare the detected magnetic flux change with the preset condition, and transmit the comparison result to the controller. Finally, the controller controls the driving component 40 to drive the wireless charging module 30 to perform corresponding operations.

[0086] For example, when the wireless charging module is in the first state (i.e., the wireless charging module is located in the receiving bin), the detection unit detects the change in magnetic flux of the wireless charging module 30 in this state. If the detected change in magnetic flux of the wireless charging module 30 meets the preset condition, a start signal is sent to the controller, and after receiving the start signal, the controller controls the driving component to drive the wireless charging module 30 to pop out of the receiving bin for wireless charging of the terminal device. If no change in the magnetic flux of the wireless charging module 30 is detected, or the detected change in magnetic flux does not meet the preset adjustment, the controller does not control the driving component 40 to drive the wireless charging module 30 to pop out of the receiving bin, which can effectively prevent the wireless charging module 30 from being frequently popped out due to misoperation and is beneficial to protecting the wireless charging module 30.

[0087] Similarly, when the wireless charging module 30 is in the second state (i.e., the wireless charging module is located outside the receiving bin), the detection unit detects the change in magnetic flux of the wireless charging module 30 in this state. If the detected change in magnetic flux of the wireless charging module 30 does not meet the preset condition, it indicates that the charging has been completed or the terminal device has been taken away, and a stop signal is sent to the controller. After receiving the stop signal, the controller controls the driving component 40 to drive the wireless charging module 30 to retract into the receiving bin to achieve automatic retraction of the wireless charging module 30 without manual operation. If the detection unit detects that the change in magnetic flux of the wireless charging module 30 meets the preset condition, the controller does not control the driving component 40 to drive the wireless charging module 30 to retract into the receiving bin, and the controller controls the wireless charging module 30 to charge the terminal device.

[0088] In one embodiment, the wireless charging device can be integrated in a computer (PC), and the controller can be the MCU (micro - control unit) of the computer.

[0089] As the second aspect of the embodiments of the present disclosure, the embodiments of the present disclosure provide a charging method for a wireless charging device, which is used for the wireless charging device in the embodiments of the present disclosure. The method includes:

[0090] S11. When the control module detects that the change in magnetic flux of the wireless charging module meets the preset condition in the first state, a first control signal is sent to the driving component. The first state is the state where the wireless charging module is located in the receiving bin.

[0091] S12. Under the control of the first control signal, the driving component drives the wireless charging module to convert from the first state to the second state to charge the terminal device. The second state is the state where the wireless charging module is located outside the receiving bin.

[0092] In this embodiment, in the first state (i.e., the wireless charging module is located in the accommodation bin), the control module detects the change in the magnetic flux of the wireless charging module and compares the detected result with a preset condition. If the detected change in magnetic flux meets the preset condition, a first control signal is sent to the driving component. Under the control of the first control signal, the driving component drives the wireless charging module to switch from the first state to the second state (i.e., from the wireless charging module being located in the accommodation bin to being located outside the accommodation bin), and then charges the terminal device. The charging method of the present disclosure embodiment cleverly uses the change in magnetic flux to automatically control the wireless charging module to pop out of the accommodation bin, without the need for manual operation, which is beneficial to improving the loosening of internal structural components caused by manual operation and can also reduce the cost of replacing structural components.

[0093] Exemplarily, the first control signal refers to an instruction for controlling the wireless charging module to pop out of the accommodation bin. This first control signal can be transmitted wirelessly or in a wired manner, and no limitation is imposed thereon.

[0094] In one implementation manner, the charging method further includes:

[0095] S21. When the control module detects that the change in the magnetic flux of the wireless charging module does not meet the preset condition in the second state, a second control signal is sent to the driving component;

[0096] S22. Under the control of the second control signal, the driving component drives the wireless charging module to reset from the second state to the first state.

[0097] In this embodiment, in the second state (i.e., the wireless charging module is located outside the accommodation bin), the control module detects the change in the magnetic flux of the wireless charging module and compares the detected result with the preset condition. If it is detected that the change in the magnetic flux of the wireless charging module does not meet the preset condition, a second control signal is sent to the driving component, so that the driving component is controlled to drive the wireless charging module to reset from the second state to the first state (i.e., from the wireless charging module being located outside the accommodation bin to being reset inside the accommodation bin).

[0098] Exemplarily, the second control signal refers to an instruction for controlling the wireless charging module to retract from outside the accommodation bin into the accommodation cavity. This second control signal can be transmitted wirelessly or in a wired manner, and no limitation is imposed thereon.

[0099] As the third aspect of the present disclosure embodiment, the present disclosure embodiment provides an electronic device including the wireless charging device in the present disclosure embodiment. Exemplarily, the electronic device may include a computer (PC) and the like.
