[0024] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0025] According to an embodiment of the present disclosure, an electronic device is provided, which can be conveniently and quickly aligned with a charging coil of a wireless charging stand in either an unfolded or closed state of the electronic device, thereby improving charging efficiency.

[0026] The electronic device may be a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, a translator, a watch, a wristband, or other wearable device. In this embodiment, the terminal device is a mobile phone. The following description uses a mobile phone as the electronic device, but is not limited to this.

[0027] Figure 1 The figure is a schematic structural diagram of an electronic device according to an exemplary embodiment. Figure 2 is a schematic diagram showing another state of an electronic device according to an exemplary embodiment.

[0028] like Figure 1 and Figure 2 As shown, the electronic device 100 includes a housing 10 and a wireless charging coil assembly 20 .

[0029] The housing 10 is an exterior component of the electronic device 100 and is used to support components such as the display screen, battery, and wireless charging coil assembly 20. The housing 10 may be rectangular, including long sides extending along the length direction of the electronic device 100 and short sides extending along the width direction.

[0030] The housing 10 includes a first housing 11 and a second housing 12. The first housing 11, serving as the main component of the electronic device 100, may be a frame-shaped structure with an opening facing the second housing 12 for the second housing 12 to pass through and be housed within the first housing 11. Specifically, the first housing 11 has a front and a back. The front of the housing 10 is where the phone's display is located, supporting the display. The back of the housing 10 houses components such as the battery and motherboard.

[0031] The second housing 12 can linearly reciprocate relative to the first housing 11 to expand or close the housing 10. In one example, the second housing 12 can linearly reciprocate relative to the first housing 11 along the width of the electronic device 100 to expand or close the housing 10 in the width direction. In another example, the second housing 12 can linearly reciprocate relative to the first housing 11 along the length of the electronic device 100 to expand or close the housing 10 in the length direction.

[0032] The second housing 12 also has a frame-like structure, and its thickness and length are smaller than those of the interior space of the first housing 11. This allows the second housing 12 to extend into the interior of the first housing 11 through the opening of the first housing 11 and, under the action of an external driving force, to perform linear reciprocating motion relative to the first housing 11. When the second housing 12 linearly moves toward the first housing 11, the housing 10 gradually closes. When the second housing 12 linearly moves away from the first housing 11, the housing 10 gradually expands.

[0033] The wireless charging coil assembly 20 is disposed in the housing 10 . The second housing 12 and the wireless charging coil assembly 20 can move linearly back and forth in the same direction relative to the first housing 11 .

[0034] When the housing 10 is unfolded or closed, the wireless charging coil assembly 20 is located at the center of the housing 10. When the housing 10 is closed, that is, when the second housing 12 is housed within the first housing 11, the wireless charging coil assembly 20 can be located at the center of the first housing 11. In this case, the wireless charging coil assembly 20 is also located at the center of the housing 10. When the electronic device 100 is placed on a wireless charging dock for charging, the wireless charging coil assembly 20 located at the center of the housing 10 facilitates alignment with the wireless charging coil on the dock, allowing for almost blind alignment during placement. When the housing 10 needs to be unfolded, the first housing 11 can remain stationary while the second housing 12 moves widthwise. At this point, the wireless charging coil assembly 20 also moves widthwise, following the second housing 12, to the center of the unfolded housing 10. This allows the wireless charging coil assembly 20 located at the center of the housing 10 to be easily aligned with the wireless charging coil on the dock during charging, allowing for almost blind alignment during placement, thereby improving charging efficiency.

[0035] In summary, in the electronic device 100 disclosed herein, when the shell 10 is in the expanded or closed state, the wireless charging coil of the electronic device 100 can be maintained at the center position of the shell 10, so as to facilitate alignment with the wireless charging coil on the wireless charging stand to improve charging efficiency.

[0036] In one embodiment, the connection between the first shell 11 and the second shell 12 can be a sliding connection. A guide rail (not shown) and a linear bearing (not shown) can be provided in the first shell 11. The guide rail can be cylindrical and extend along the length or width direction of the electronic device 100. The linear bearing is sleeved on the outside of the guide rail and can reciprocate along the extension direction of the guide rail. The linear bearing can be provided with a plurality of evenly distributed load-bearing balls, which are in contact with the guide rail. When the linear bearing moves along the guide rail, the load-bearing balls roll relative to the guide rail. The load-bearing balls are in point contact with the guide rail. When the load-bearing balls roll relative to the guide rail, the friction resistance generated by the rotation of the load-bearing balls is small, thereby achieving high-precision and smooth motion.

[0037] In one embodiment, the guide rail may also be provided with a groove, which is used to cooperate with the load-bearing ball in the linear bearing. The load-bearing ball rolls relative to the guide rail in the groove, which can ensure that when the load-bearing ball and the guide rail are matched, the load-bearing ball and the guide rail are prevented from being out of contact due to tolerance, collision and other problems, and the resistance to lateral deformation can also be enhanced. Not only that, the low friction reduces the wear of the mechanism components, avoids damage to the mechanism components due to wear, reduces the frequency of replacement or maintenance of the mechanism components, and reduces costs. In addition, when a flexible roll-up screen is provided on the first shell 11 and the second shell 12, the linear bearing moves along the linear guide rail, which can ensure that the display surface of the flexible screen is smoothly unfolded and the user experience is good.

[0038] Furthermore, the flexible screen is provided on the front of the first shell 11 and the second shell 12. The flexible screen can be in an expanded state or a closed state as the second shell 12 makes a linear reciprocating motion relative to the first shell 11.

[0039] Specifically, in some embodiments, a reel (not shown) may be provided within the first housing 11, with one end of the flexible screen wound around the reel and the other end supported on the second housing. The reel is located close to the side of the first housing 11 that is away from the second housing 12. The flexible screen may include a fixed end and a movable end. The fixed end is fixed to the reel within the first housing 11, and the other end is wound around the reel multiple times, passes around the upper surface of the first housing 11 and the upper surface of the second housing 12, and is fixed to the second housing 12. The reel follows the second housing 12 as it approaches or moves away from the first housing 11 to unfold or retract the screen.

[0040] In some embodiments, the electronic device 100 may further include a drive mechanism 30, disposed on the first housing 11 and connected to the second housing 12 and the wireless charging coil assembly 20, to drive the second housing 12 and the wireless charging coil assembly 20 to move linearly back and forth in the same direction relative to the first housing 11. Based on the received unfolding screen command, the electronic device 100 controls the drive mechanism 30 to drive the second housing 12 to move linearly away from the first housing 11. Simultaneously, the drive mechanism 30 may also drive the wireless charging coil assembly 20 to move in the same direction as the movement of the second housing 12, so that the wireless charging coil assembly 20 is located at the center of the unfolded housing 10, facilitating alignment with the wireless charging coil of the wireless charging stand.

[0041] In some embodiments, the drive mechanism 30 may include a drive motor 31, a first transmission assembly, and a second transmission assembly. The drive motor 31 is fixed to the first housing 11. One end of the first transmission assembly is connected to the drive motor 31, and the other end is connected to the second housing 12. The second transmission assembly connects the first transmission assembly and the wireless charging coil assembly 20. The drive motor 31 drives the first transmission assembly and the second transmission assembly, respectively, to cause the second housing 12 and the wireless charging coil assembly 20 to move linearly back and forth in the same direction relative to the first housing 11.

[0042] The drive motor 31 drives the first transmission assembly to move the second housing 12 a first distance away from the first housing 11. The second housing 12 and the first housing 11 unfold, and the screen is extended. Simultaneously, the first transmission assembly drives the second transmission assembly to move the wireless charging coil assembly 20 in the same direction as the second housing 12 by a second distance, which is half the first distance. The transmission ratio of the first and second transmission assemblies is varied to achieve simultaneous movement of the first housing 11 by the first distance and the wireless charging coil assembly 20 by a second distance, which is half the first distance. For example, the transmission ratio of the first and second transmission assemblies can be 2:1. This allows the wireless charging coil assembly 20 to be positioned at the center of the housing 10, facilitating alignment with the wireless charging coil of the wireless charging stand. The driving motor 31 drives the first transmission assembly to move the second shell 12 a first distance closer to the first shell 11. The second shell 12 is closed with the first shell 11, and the screen is in a retracted state. At the same time, the first transmission assembly drives the second transmission assembly to move the wireless charging coil assembly 20 in the same direction as the second shell 12, and the distance at one end is the second distance, wherein the second distance is half of the first distance, so that the wireless charging coil assembly 20 is located in the center of the shell 10, which is convenient for alignment with the wireless charging coil of the wireless charging stand.

[0043] In this disclosure, a single drive motor 31, in conjunction with the first and second transmission assemblies, simultaneously drives the second housing 12 and the wireless charging coil assembly 20 in the same direction. This allows the wireless charging coil assembly 20 to be positioned centrally within the housing 10, facilitating alignment with the wireless charging coil of the wireless charging stand. Furthermore, a single drive motor 31 provides energy savings and facilitates control, facilitating the synchronous movement of the wireless charging coil assembly 20 and the second housing 12.

[0044] As an example, the drive motor can be a linear motor. The first transmission assembly is a first rack 32, one end of the first rack is connected to the linear motor, and the other end is connected to the second shell 12. The second transmission assembly includes a first driving gear (not shown), a first reducer 33, a first driven gear (not shown) and a second rack 34, the first driving gear is meshed with the first rack 32, the input end of the first reducer 33 is connected to the first driving gear, the output end of the reducer 33 is connected to the first driven gear, one end of the second rack 34 is meshed with the first driven gear, and the other end is connected to the wireless charging coil assembly 20. The speed of the first driven wheel can be adjusted by the reducer 33 so that the distance the first driven wheel drives the second rack 34 to move is half the distance the first driving gear drives the first rack 32 to move.

[0045] The first rack 32 can extend along the width of the electronic device 100, with one end connected to the telescopic end of the linear motor and the other end connected to the back of the second shell 12. The linear motor drives the first rack 32 to move along the width direction to move the second shell 12 closer to or farther away from the first shell 11. The first rack 32 moves along the width direction, driving the driving gear to rotate. After being decelerated by the reducer 33, the driven gear rotates, driving the second rack 34 to move along the width direction, so that the wireless charging coil assembly 20 also moves in the same direction as the movement of the second shell 12, that is, it moves with the second shell 12. This ensures that the wireless charging coil assembly 20 is located in the center of the shell 10 when the shell 10 is in the expanded or closed state, so as to facilitate alignment with the wireless charging coil of the wireless charging stand.

[0046] In the present disclosure, the wireless charging coil assembly 20 and the second housing 12 are moved in the same direction by cooperating with a linear motor and a gear rack, but the present invention is not limited thereto.

[0047] As another example, the drive motor 31 is a rotary motor. The first transmission assembly includes a first transmission rod and a first nut. The first transmission rod is provided with a first threaded portion and a second driving gear. The first transmission rod is connected to the output shaft of the rotary motor. The first nut is threadedly connected to the first threaded portion on the first transmission rod and fixedly connected to the second shell. The second transmission assembly includes a second transmission rod and a second nut. The second transmission rod is provided with a second threaded portion and a second driven gear. The second driven gear is connected to the second driving gear through a second reducer. The second nut is threadedly connected to the second threaded portion on the second transmission rod and connected to the wireless charging coil assembly 20. The rotation speed of the second driven wheel can be adjusted by the second reducer so that the second driven wheel drives the second transmission rod to rotate at a speed half of the rotation speed of the first transmission rod, so that the first nut drives the second shell to move a first distance, and the second nut drives the wireless charging coil to move a second distance that is half of the first distance.

[0048] The first transmission rod can extend in the width direction of the electronic device 100, with one end connected to the output shaft of the rotary motor and the other end threadedly connected to a first nut. The first nut is connected to the second housing 12. The rotary motor rotates, driving the first transmission rod to rotate, causing the first nut to drive the second housing 12 to move along the width direction of the electronic device 100. At the same time, the second driving gear on the first transmission rod drives the second driven gear to rotate through the second reducer, thereby driving the second transmission rod to rotate, so that the second nut threadedly connected to the second transmission rod drives the wireless charging coil assembly 20 to move along the width direction of the electronic device 100.

[0049] In some embodiments, the wireless charging coil assembly 20 may include a coil support (not shown) and a wireless charging coil mounted on the coil support. The coil support is connected to a drive mechanism. The coil support supports the wireless charging coil. The drive mechanism 30 drives the wireless charging coil via the coil support.

[0050] In some embodiments, two drive mechanisms 30 are provided, one on opposite sides of the first housing 11 and connected to the second housing 12 and the wireless charging coil assembly 20, respectively. The two drive mechanisms 30 drive the second housing 12 and the wireless charging coil assembly 20 to move, respectively, making the movement of the second housing 12 and the wireless charging coil assembly 20 smoother.

[0051] According to the present disclosure, a method for controlling an electronic device is also provided, which can control the expansion or closing of a shell and adjust the position of the wireless charging coil to facilitate alignment with the wireless charging stand.

[0052] Figure 3 FIG. 1 is a flow chart of a method for controlling an electronic device according to an exemplary embodiment. Figure 3 As shown, the electronic device control method 200 provided by the present disclosure is applied to the electronic device 100 of any of the above embodiments. The electronic device control method 200 includes step S11 and step S12.

[0053] In step S11 , a screen expansion or screen closing instruction is received.

[0054] The screen expansion or screen closing instruction may be an instruction triggered by the user pressing a button on the electronic device 100 , or an instruction triggered by touching a virtual button on the screen.

[0055] In step S12 , the driving mechanism is controlled to drive the second housing 12 of the housing 10 and the wireless charging coil assembly 20 to move linearly back and forth in the same direction relative to the first housing 11 .

[0056] According to the received screen unfolding instruction, the driving mechanism is controlled to drive the second shell 12 to move away from the first shell 11, so that the screen is unfolded, and at the same time drive the wireless charging coil assembly 20 to move in the same direction as the movement direction of the second shell 12 to adjust the position of the wireless charging coil assembly 20 to facilitate alignment with the wireless charging base.

[0057] According to the screen closing instruction received, the driving mechanism is controlled to drive the second shell 12 to move closer to the first shell 11, so that the screen is closed, and at the same time drive the wireless charging coil assembly 20 to move in the same direction as the movement direction of the second shell 12 to adjust the position of the wireless charging coil assembly 20 to facilitate alignment with the wireless charging base.

[0058] In the present disclosure, the second shell 12 and the wireless charging coil assembly 20 are driven to move in the same direction by controlling the driving mechanism. When the screen is unfolded or closed, the position of the wireless charging coil assembly 20 is adjusted accordingly, and the wireless charging stand can be more conveniently aligned when the screen is unfolded or closed.

[0059] In one embodiment, step S12 includes: controlling the driving mechanism 30 to drive the second shell 12 of the shell 10 to move a first distance along the first direction relative to the first shell 11, and controlling the driving mechanism 30 to drive the wireless charging coil assembly 20 to move a second distance along the first direction relative to the first shell 11, wherein the second distance is half of the first distance.

[0060] In the initial state (also known as the screen-closed state), the wireless charging coil assembly 20 is located at the center of the first housing 11. Based on the received screen-expanding instruction, the control driving mechanism drives the second housing 12 to move a first distance away from the first housing 11 in a first direction (e.g., the width of the electronic device 100), thereby expanding the screen. This simultaneously drives the wireless charging coil assembly 20 to move a second distance in the first direction, where the second distance is half of the first distance. This allows the wireless charging coil assembly 20 to move from the center of the first housing 11 to the center of the housing 10 in the screen-expanded state, thereby more conveniently aligning with the wireless charging base.

[0061] According to the received screen closing instruction, the driving mechanism is controlled to drive the second shell 12 to move a first distance toward the direction opposite to the first direction close to the first shell 11, so that the screen is closed, and at the same time drive the wireless charging coil assembly 20 to move a second distance in the direction opposite to the first direction, so that the wireless charging coil assembly 20 moves from the center position of the shell 10 in the screen unfolded state to the center position of the first shell 11, so as to be more conveniently aligned with the wireless charging stand.
