Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically, to mobile terminal bases, electronic devices, and methods of using them. Background Technology

[0002] Tablet computers and other terminal products can be used with peripherals such as keyboards and touchpads to achieve a user experience similar to that of a laptop. Some existing products such as leather keyboard cases and tablet docks can achieve this function.

[0003] However, existing products suffer from unreasonable structural and functional configurations. Summary of the Invention

[0004] This application provides a mobile terminal base, an electronic device, and a method for using the electronic device to solve the problem of unreasonable structure and functional settings in existing products.

[0005] In a first aspect, embodiments of this application provide a mobile terminal base, including a support plate, a first cover plate, a touch panel, and a power-connecting structure. The support plate has a first side. The first cover plate is foldably connected to the first side of the support plate and can be folded to a first state opposite to the support plate. The touch panel is disposed on the first cover plate. The power-connecting structure is disposed on the first cover plate and electrically connected to the touch panel.

[0006] In the first state, the first cover plate can cover the mobile terminal placed on the support plate and pair the power connection structure on it with the power supply structure disposed on the mobile terminal or on the support plate, so that the power supply structure supplies power to the touch panel through the power connection structure.

[0007] In this embodiment of the mobile terminal base, the touchpad is mounted on a first cover plate that is foldably connected to the support plate, without occupying space on the support plate, thus allowing more space on the support plate to place a keyboard or other structures. Furthermore, this arrangement allows the first cover plate to cover the mobile terminal placed on the support plate, which provides some protection to the mobile terminal and allows the touchpad to be powered by either the mobile terminal or the support plate.

[0008] In this embodiment, the first cover plate can cover the mobile terminal to achieve the function of protecting or storing the mobile terminal. At the same time, in the state of protection or storage, it can also maintain power supply to the touchpad, so the user does not need to pay attention to the touchpad's battery level. The combination of structure and function is reasonable and convenient to use.

[0009] In one possible implementation, the power connection structure includes a first charging coil and a battery; the first charging coil is electrically connected to the battery, which supplies power to the touchpad. The power supply structure includes a second charging coil disposed on the mobile terminal. When the mobile terminal is placed on the support plate, the first charging coil on the first cover plate in a first state is paired with the second charging coil to enable the mobile terminal to charge the battery through the pairing of its second charging coil and the first charging coil.

[0010] This implementation proposes a structure for wireless charging via a coil. The coil size can be relatively large and can be completely integrated inside the mobile terminal or the first cover plate without protruding from the surface, thus not affecting the appearance of the mobile terminal or the first cover plate. Simultaneously, the coil occupies relatively little space in the thickness direction of the structure, yet it can be easily configured to have a large coverage area. Therefore, the relative position requirements of the first and second charging coils are less stringent; even if they are slightly misaligned, normal charging functionality can still be maintained.

[0011] In one possible implementation, the power connection structure includes a charging Pogo Pin (i.e., a charging spring pin) and a battery; the charging Pogo Pin is electrically connected to the battery, which supplies power to the touchpad. The power supply structure includes a charging Pad (i.e., a charging pad, used in conjunction with the charging Pogo Pin) disposed on the mobile terminal. When the mobile terminal is placed on the support plate, the charging Pogo Pin on the first cover plate in the first state pairs with the charging Pad, enabling the mobile terminal to charge the battery through the pairing of its charging Pad and the charging Pogo Pin.

[0012] This implementation proposes a structure that achieves wireless charging through the cooperation of a charging Pogo Pin and a charging Pad. Charging is achieved by pairing the charging Pogo Pin and the charging Pad, which is an improvement over wired charging and offers higher charging efficiency.

[0013] In one possible implementation, the charging Pogo Pin extends vertically out of the surface of the first cover plate; the corresponding charging Pad is located on the back of the mobile terminal.

[0014] In this implementation, by having the charging Pogo Pin and the charging Pad extend from their respective ground locations, they can be precisely engaged and connected to enable charging when the first cover plate covers the mobile terminal, making it convenient to use.

[0015] In one possible implementation, the mobile terminal base further includes a second cover plate, which is foldably connected to a second side of the support plate and can be folded to a second state opposite to the support plate; the second side and the first side are opposite to each other. The power connection structure includes a charging Pogo Pin and a battery; the charging Pogo Pin is electrically connected to the battery, which supplies power to the touchpad; the charging Pogo Pin extends from the side of the first cover plate away from the first side along the plate surface where the first cover plate is located. The power supply structure includes a charging port disposed on the support plate, a charging Pad disposed on the side of the second cover plate away from the second side, and a flexible circuit board electrically connecting the charging port and the charging Pad. When the first cover plate is in its first state and the second cover plate is in its second state, the charging Pogo Pin pairs with the charging Pad so that an external power source connected to the charging port can charge the battery through the pairing of the charging Pad and the charging Pogo Pin.

[0016] This implementation includes a second cover plate, which, along with the aforementioned first cover plate, covers the mobile terminal from both sides, providing further protection and storage. Furthermore, the charging Pogo Pin (connecting the power supply) and the charging Pad (power supply) are positioned outside the first and second cover plates, respectively. This allows the charging Pogo Pin and the charging Pad to electrically engage when the mobile terminal is covered, enabling charging of the touchpad. In other words, this implementation allows the combination of the first and second cover plates to simultaneously provide protection and storage for the mobile terminal, while also enabling touchpad charging under these protected conditions.

[0017] In one possible implementation, the mobile terminal base further includes a second cover plate, which is foldably connected to a second side of the support plate and can be folded to a second state opposite to the support plate; the second side and the first side are opposite each other. When the first cover plate is in its first state and the second cover plate is in its second state, the first cover plate and the second cover plate can respectively cover the mobile terminal placed on the support plate from both sides of the support plate.

[0018] In this implementation, the first cover plate, in combination with the second cover plate, covers and protects the mobile terminal from both sides, enabling the mobile terminal to be stored. On the other hand, even when stored, it can still maintain power supply to the touchpad on the first cover plate, making it convenient to use and a reasonable combination.

[0019] In one possible implementation, when the first cover is in its first state, the third suction member on the first cover is attracted to the mobile terminal. When the second cover is in its second state, the second suction member on the second cover is attracted to the mobile terminal.

[0020] By setting up various suction components, the covering state between the first / second cover plate and the support plate can be maintained to a certain extent, while also allowing for easy removal of the covering state, making it convenient to use. The suction method of the third / second suction component mentioned here can be magnetic.

[0021] In one possible implementation, the second cover plate includes a first sub-plate foldably connected to the second side and a second sub-plate foldably connected to the first sub-plate. The second sub-plate is provided with a second suction member capable of suctioning the mobile terminal. The support plate is provided with a fixing groove so that the mobile terminal can be tilted and supported by the first sub-plate with its lower edge limited to the fixing groove and its back side suctioned to the second sub-plate.

[0022] In this implementation, by setting the second cover plate as a first sub-plate and a second sub-plate that can be folded relative to each other, and combining it with the fixing groove set on the support plate, the tilt support of the mobile terminal can be realized.

[0023] In one possible implementation, there are multiple fixing slots, which are distributed in parallel intervals along a direction perpendicular to the second side.

[0024] In this implementation, multiple fixing slots are set up, and combined with the foldable connection between the first sub-board and the support plate, and the foldable connection between the second sub-board and the first sub-board, it is possible to easily realize the use of mobile terminals for tilt support at different angles.

[0025] In one possible implementation, the first cover plate has a folding angle of 360° relative to the support plate, and the second cover plate has a folding angle of 360° relative to the support plate.

[0026] In this implementation, the first and second cover plates can fold at an angle of 360°, allowing them to fold to the side of the support plate that supports the mobile terminal, or to the other side of the support plate; they can also fold to other angles to achieve tilt support for the mobile terminal, etc. In other words, different combinations of use are possible.

[0027] In one possible implementation, the mobile terminal base includes a flexible substrate, with a first cover plate, a support plate, and a second cover plate sequentially and spaced apart from each other on the surface of the flexible substrate.

[0028] In this implementation, the flexible substrate can be a single flexible material supporting a surface material, with all parts being bendable flexible structures; alternatively, it may not be entirely flexible, but only partially flexible between the first cover plate and the support plate, and between the second cover plate and the support plate, enabling foldable connections between the first cover plate and the support plate, and between the second cover plate and the support plate. Preferably, the portions of the flexible substrate between the first cover plate and the support plate, and between the second cover plate and the support plate, are entirely flexible. Optionally, the first cover plate, the support plate, and the second cover plate are connected to the flexible substrate by bonding or covering, and the portions of the flexible substrate corresponding to the first cover plate, the support plate, and the second cover plate can be made of flexible material or rigid material.

[0029] In one possible implementation, the flexible substrate is made of a sheath.

[0030] In this implementation, the flexible substrate is a sheath; in other implementations, the flexible substrate can also be made of flexible rubber, silicone or other flexible materials.

[0031] In one possible implementation, the foldable connection structure between the first cover plate and the support plate is: a hinge structure is provided, which connects the support plate and the first cover plate.

[0032] This implementation proposes a hinged connection between the first cover plate and the support plate, allowing for a foldable connection; the specific hinge structure can be selected and configured as needed.

[0033] In one possible implementation, the foldable connection structure between the first cover plate and the support plate is: a first flexible connecting strip is provided, which connects the support plate and the first cover plate.

[0034] This implementation proposes a foldable connection between the first cover plate and the support plate using a first flexible connecting strip; the first flexible connecting strip can be made of leather, flexible rubber, mesh woven material, etc.

[0035] In one possible implementation, with the mobile terminal placed on a support plate and covered by a first cover plate, a strip space is defined between the first flexible connecting strip and the end face of the corresponding mobile terminal for accommodating the stylus of the mobile terminal.

[0036] This implementation method can reliably accommodate the stylus while the first cover plate closes the mobile terminal.

[0037] In one possible implementation, a fourth suction member is fixed on the first flexible connecting strip, which is used to suction the corresponding end face of the mobile terminal when no stylus is placed in the strip space, so as to drive the first flexible connecting strip to approach and adhere to the corresponding end face of the mobile terminal.

[0038] This implementation is compatible with both usage modes: when the stylus is stored and when it is not. When the stylus is stored, it is housed in the aforementioned strip space, supporting the first flexible connecting strip and maintaining its shape. When the stylus is not stored, the fourth suction member is attached to the corresponding end face of the mobile terminal, bringing the first flexible connecting strip to fit the corresponding end face of the mobile terminal and maintaining its shape.

[0039] In one possible implementation, the first flexible connecting strip is made of an elastic material and is elastically stretchable or shortenable to adapt to the mobile terminal with or without a stylus.

[0040] Optionally, the first flexible connecting strip is made of a variable elastic material only in the middle section to accommodate the stylus; while it is made of a non-elastic material that cannot be stretched or shortened on both sides to maintain the spacing between the first cover plate and the support plate.

[0041] In this implementation, when a stylus is set, the first flexible connecting strip can be elastically stretched to cover the stylus; when no stylus is set, the first flexible connecting strip can be shortened to cover the end face of the mobile terminal.

[0042] In one possible implementation, a keyboard assembly is provided on the support plate; the keyboard assembly is capable of communicating with the mobile terminal.

[0043] In this setup, a keyboard assembly is placed on the support plate, and a touchpad is placed on the first cover plate, which can provide a corresponding input method for the mobile terminal.

[0044] Furthermore, in cases where a mounting slot is provided on the support plate, the keyboard assembly is located on the side closer to the first cover plate, and the mounting slot is located on the side closer to the second cover plate. This ensures that keyboard operation is not affected when the mobile terminal is supported by the mounting slot.

[0045] The keyboard assembly and the mobile terminal can communicate wirelessly via Bluetooth or other wireless methods. The aforementioned touchpad can wirelessly connect to the mobile terminal via Bluetooth, Wi-Fi, etc.; of course, it can also be connected via a wired connection.

[0046] Secondly, embodiments of this application provide an electronic device including a mobile terminal and the aforementioned mobile terminal base. The mobile terminal can be placed on a support plate. In a first state, a power connection structure and a power supply structure disposed on the mobile terminal or disposed on the support plate are paired, and the power supply structure supplies power to the touchpad through the power connection structure.

[0047] In the electronic device of this application embodiment, the mobile terminal base can be used in combination with the mobile terminal to cover and protect the mobile terminal. At the same time, when covering the mobile terminal, the power supply structure can supply power to the touch panel through the power connection structure, so the user does not need to pay extra attention to the touch panel's power status.

[0048] In one possible implementation, the touchpad and the mobile terminal are connected via wireless communication.

[0049] In this implementation, the wireless communication connection can be via Bluetooth or other methods.

[0050] Thirdly, embodiments of this application provide an electronic device, which includes a mobile terminal, a stylus, and a mobile terminal base. The mobile terminal has a screen on its front and a first, second, and third attracting member arranged sequentially from bottom to top along its back; a fourth attracting member is provided on the top surface of the mobile terminal. A fifth attracting member matching the fourth attracting member is provided on the side of the stylus, for attracting the stylus to the top surface of the mobile terminal. The mobile terminal base includes a flexible substrate, a first cover plate, a support plate, and a second cover plate. The first cover plate, support plate, and second cover plate are sequentially and spaced apart and fixed to the surface of the flexible substrate. The portion of the flexible substrate between the first cover plate and the support plate is a first flexible connecting strip, which allows the first cover plate to fold 360° relative to the support plate. The portion of the flexible substrate between the second cover plate and the support plate is a second flexible connecting strip, which allows the second cover plate to fold 360° relative to the support plate. A keyboard assembly is provided on the side of the support plate near the first cover plate, and a keyboard assembly is provided on the side of the support plate near the second cover plate. The first cover plate has multiple sequentially spaced fixing grooves on one side. The second cover plate includes a second sub-plate and a first sub-plate, which are respectively connected to a flexible substrate. The first sub-plate and the support plate are spaced apart to allow the first sub-plate to fold relative to the support plate, and the second sub-plate and the first sub-plate are spaced apart to allow the second sub-plate to fold relative to the first sub-plate. The first sub-plate has a first suction member adapted to a first attracted component, the second sub-plate has a second suction member adapted to a second attracted component, the first cover plate has a third suction member adapted to a third attracted component, and the first flexible connecting strip has a fourth suction member adapted to a fourth attracted component. The distance between the first and second attracted components in the vertical direction of the mobile terminal is approximately equal to the distance between the first and second suction members in the direction from the first sub-plate to the second sub-plate. The mobile terminal base also includes a touch panel and a power connection structure. The touch panel is disposed on the first cover plate, and the power connection structure is disposed on the first cover plate and electrically connected to the touch panel. When the first cover plate is folded over to cover the mobile terminal placed on the support plate, the power connection structure and the power supply structure disposed on the mobile terminal or on the support plate are paired so that the power supply structure supplies power to the touch panel through the power connection structure.

[0051] The electronic device provided in this application embodiment, through a specific mobile terminal base structure and functional settings, can support multiple usage modes of the mobile terminal, provide peripherals such as touchpad and keyboard components for the mobile terminal, power the touchpad in the storage state, and realize reasonable storage of the mobile terminal and stylus. The functional and structural design is reasonable and convenient to use.

[0052] Fourthly, embodiments of this application provide a method for using an electronic device, which is based on the electronic device described in the third aspect above, and the electronic device can be used in any of the following combinations of states:

[0053] First combined state: The mobile terminal is detached from the mobile terminal base and can be used alone or with a stylus;

[0054] Second combined state: The first cover plate and the second cover plate of the mobile terminal base are unfolded relative to the support plate, the mobile terminal screen is stacked on the second cover plate with the screen facing upward, and the first suction member on its back is correspondingly suctioned to the first suction member and the second suction member is correspondingly suctioned to the second suction member.

[0055] Third combination state: The support plate is placed horizontally, the first sub-plate is tilted upwards and forms an acute angle with the support plate; the mobile terminal is tilted and supported by the first sub-plate, and the back of the mobile terminal is attached to the second sub-plate and its second suction part is attached to the second suction part of the second sub-plate, and the bottom of the mobile terminal is limited to one of the fixing slots; the stylus is held in hand or attached to the top surface of the mobile terminal.

[0056] Fourth combination state: The mobile terminal screen is stacked on the second cover plate with the screen facing up, and the first suction member on its back is correspondingly suctioned to the first suction member and the second suction member is correspondingly suctioned to the second suction member; the support plate is folded to the side of the second cover plate away from the mobile terminal and attached to the second cover plate, and the first cover plate is folded to the side of the support plate away from the mobile terminal.

[0057] Fifth combined state: The mobile terminal is placed on the support plate with its top surface facing the first cover plate and its back surface facing upward; the first cover plate is flipped over to cover the back of the mobile terminal, and its third suction member is attached to the third suction member on the back of the mobile terminal; the second cover plate is flipped over to cover the back of the mobile terminal, and its first suction member is attached to the first suction member on the back of the mobile terminal, and its second suction member is attached to the second suction member on the back of the mobile terminal; in the fifth combined state, the power supply structure supplies power to the touchpad through the power connection structure.

[0058] The method of using the electronic device provides several combinations of states of the electronic device in the third aspect.

[0059] Fifthly, this application also provides a mobile terminal base, including a support plate, a first cover plate, and a touch panel, with the touch panel disposed on the first cover plate. The support plate has a first side edge, and the first cover plate is foldably connected to the first side edge of the support plate via a first flexible connecting strip. The first flexible connecting strip includes elastic and non-elastic regions arranged sequentially along a direction parallel to the first side edge. The elastic regions can be elastically stretched or shortened to accommodate the storage or non-storage of a stylus; the non-elastic regions cannot be stretched or shortened. A main battery is disposed on the support plate, and the main battery is electrically connected to the touch panel via a flexible circuit board for supplying power to the touch panel, wherein the flexible circuit board extends from the non-elastic region through the first flexible connecting strip.

[0060] In this embodiment of the mobile terminal base, the touchpad is mounted on a first cover plate that is foldably connected to the support plate, without occupying space on the support plate, thus providing more space on the support plate for placing a keyboard or other structures. Furthermore, by setting a first flexible connecting strip to distinguish between elastic and non-elastic areas, the flexible circuit board passes through the non-elastic area via the first flexible connecting strip, preventing it from being stretched and damaged. The elastic area can be used to accommodate situations where a stylus may or may not be stored. This structure and functional design are reasonable, convenient, and reliable to use.

[0061] In one possible implementation, the middle portion of the first flexible connecting strip is set as an elastic region, and the two sides are set as non-elastic regions.

[0062] This setup effectively maintains the spacing between the support plate and the first cover plate, and also provides good storage for the stylus.

[0063] In one possible implementation, the mobile terminal base further includes a second cover plate, which is connected to the second side of the support plate opposite to its first side plate via a second flexible connecting strip, and the second cover plate is foldable relative to the support plate.

[0064] This implementation method uses a first cover plate and a second cover plate, which can respectively cover the mobile terminal placed on the support plate from both sides. It has a simple structure, is easy to use, and can reliably protect the mobile terminal.

[0065] Sixthly, embodiments of this application also provide an electronic device, including a mobile terminal and a mobile terminal base as described in the fifth aspect. The mobile terminal can be placed on the support plate and covered by a first cover plate. Simultaneously, a touchpad disposed on the first cover plate can be powered via a flexible circuit board passing through the non-elastic area of ​​the first flexible connecting strip.

[0134] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0135] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0136] Example

[0137] See also Figure 1 and Figure 2 This application provides an electronic device 100, which includes a mobile terminal 20 and a mobile terminal dock 40. The mobile terminal 20 can be a commonly used product such as a tablet computer, mobile phone, television, or e-reader; the mobile terminal dock 40 can be used in combination with the mobile terminal 20, for example, as a peripheral device such as a mouse or keyboard for the mobile terminal 20.

[0138] See also Figure 1 and Figure 2 The mobile terminal base 40 provided in this embodiment includes a support plate 42, a first cover plate 47, a touch panel 48, and a power connection structure 55. The support plate 42 has a first side 45. The first cover plate 47 is foldably connected to the first side 45 of the support plate 42 and can be folded to a first state opposite to the support plate 42 (see...). Figure 1 A touchpad 48 is disposed on a first cover plate 47. A power connection structure 55 is disposed on the first cover plate 47 and electrically connected to the touchpad 48. In a first state, the first cover plate 47 can cover the mobile terminal 20 placed on the support plate 42, and pair the power connection structure 55 on it with the power supply structure 56 disposed on the mobile terminal 20 or disposed on the support plate 42, so that the power supply structure 56 supplies power to the touchpad 48 through the power connection structure 55.

[0139] In the mobile terminal base 40 of this embodiment, the touchpad 48 is disposed on the first cover plate 47 which is foldably connected to the support plate 42, without occupying space on the support plate 42, so that there is more space on the support plate 42 for placing the keyboard or other structures; and, through this arrangement, there is a state in which the first cover plate 47 covers the mobile terminal 20 placed on the support plate 42, which can provide a certain degree of protection for the mobile terminal 20, and just so that the touchpad 48 can be powered by the power supply structure 56 of the mobile terminal 20 or by the power supply structure 56 at the support plate 42.

[0140] In this embodiment, the first cover plate 47 can cover the mobile terminal 20 to achieve the function of protecting or storing the mobile terminal 20. At the same time, in the protected or stored state, it can also maintain power supply to the touch panel 48, so the user does not need to pay attention to the power of the touch panel 48. The structure and function combination is reasonable and convenient to use.

[0141] In this embodiment, optionally, a keyboard assembly 43 is provided on the support plate 42. The keyboard assembly 43 can communicate with the mobile terminal 20. In this configuration, the keyboard assembly 43 is provided on the support plate 42, and a touchpad 48 is provided on the first cover plate 47, which can provide a corresponding input method for the mobile terminal 20. Since the touchpad 48 is provided on the first cover plate 47, the keyboard assembly 43 has a larger installation space without reducing its size.

[0142] See also Figure 1 and 2 In this embodiment, the mobile terminal base 40 further includes a second cover plate 49, which is foldably connected to the second side 46 of the support plate 42 and can be folded to a second state opposite to the support plate 42 (see...). Figure 1 The second side 46 and the first side 45 are opposite each other. When the first cover plate 47 is in its first state and the second cover plate 49 is in its second state, the first cover plate 47 and the second cover plate 49 can cover the mobile terminal 20 placed on the support plate 42 from both sides. In this implementation, the first cover plate 47 and the second cover plate 49 together cover and protect the mobile terminal 20 from both sides, realizing the storage of the mobile terminal 20. On the other hand, in the stored state, the touch panel 48 on the first cover plate 47 can still be powered, making it convenient to use. Optionally, in the covered state, the first cover plate 47 and the second cover plate 49 basically cover most of the surface of the mobile terminal 20 to provide more comprehensive protection. Of course, a certain gap between the two is allowed. When needed, the first cover plate 47 and the second cover plate 49 can also be provided with a structure that can be interlocked (not shown in the figure) so that the first cover plate 47 and the second cover plate 49 are connected to each other when covered.

[0143] In one possible implementation, when the first cover plate 47 is in its first state, the third suction member 66 on the first cover plate 47 is attracted to the mobile terminal 20. When the second cover plate 49 is in its second state, the second suction member 65 on the second cover plate 49 is attracted to the mobile terminal 20. By providing various suction members, the covering state between the first cover plate 47 / second cover plate 49 and the support plate 42 can be maintained to a certain extent, while the covering state can also be easily released, making it convenient to use. The suction method of the third suction member 66 / second suction member 65 mentioned here can be magnetic attraction, and the third suction member 66 / second suction member 65 can be a sheet-like magnet.

[0144] In one possible implementation, the second cover plate 49 includes a first sub-plate 50 foldably connected to the second side 46 and a second sub-plate 51 foldably connected to the first sub-plate 50. The second sub-plate 51 is provided with a second suction member 65 capable of attracting the mobile terminal 20. The support plate 42 is provided with a fixing groove 44, so that the mobile terminal 20 can be tilted and supported by the first sub-plate 50 with its lower edge limited to the fixing groove 44 and its back surface 22 attracted to the second sub-plate 51. Optionally, there are multiple fixing grooves 44, which are distributed in parallel intervals along a direction perpendicular to the second side 46. In this implementation, by setting the second cover plate 49 as a first sub-plate 50 and a second sub-plate 51 that can be folded relative to each other, and combining it with the fixing grooves 44 provided on the support plate 42, the tilted support of the mobile terminal 20 can be realized. When multiple fixing grooves 44 are provided, it is convenient to realize the tilted support of the mobile terminal 20 at different angles. Optionally, see Figure 3 The fixing groove 44 is a strip-shaped groove whose extension direction is approximately parallel to the second side 46. The fixing groove 44 is formed by a downward indentation from the surface of the support plate 42, and the inclination angle of the fixing groove 44 varies depending on the corresponding support angle. When needed, one side of the mobile terminal 20 is supported in the corresponding fixing groove 44, and the back surface 22 is approximately attached to the second sub-plate 51 to achieve relative position fixation. At this time, the support plate 42, the mobile terminal 20, and the first sub-plate 50 form a triangular structure, achieving stable support for the mobile terminal 20. When it is necessary to adjust the support angle of the mobile terminal 20, the fixing groove 44 is replaced, and the included angle between the first sub-plate 50 and the support plate 42, and between the first sub-plate 50 and the second sub-plate 51, can be adaptively adjusted to achieve another support angle.

[0145] See Figure 2 and Figure 3 In the case where a fixing slot 44 is provided on the support plate 42, the keyboard assembly 43 is located on the side closer to the first cover plate 47, and the fixing slot 44 is located on the side closer to the second cover plate 49. Thus, when the mobile terminal 20 is supported by the fixing slot 44, keyboard operation is not affected.

[0146] The keyboard assembly 43 and the mobile terminal 20 can communicate wirelessly via Bluetooth or other wireless methods. The aforementioned touchpad 48 can also wirelessly connect to the mobile terminal 20 via Bluetooth, Wi-Fi, or other wireless methods; of course, it can also be connected via a wired connection.

[0147] In one possible implementation, the first cover plate 47 and the second cover plate 49 are both foldable at a 360° angle relative to the support plate 42. This 360° folding angle allows both covers to fold to the side of the support plate 42 supporting the mobile terminal 20, or to the other side; they can also be folded to other angles to provide tilted support for the mobile terminal 20. In other words, different combinations of uses are possible, which will be described in detail below.

[0148] See also Figures 1-3 In this embodiment, the mobile terminal base 40 includes a flexible substrate 41, with a first cover plate 47, a support plate 42, and a second cover plate 49 sequentially and spaced apart from each other on the surface of the flexible substrate 41. In this implementation, the flexible substrate 41 can be a single flexible material support surface, with all parts being bendable flexible structures; or it can be less entirely flexible, with only some flexible areas existing between the first cover plate 47 and the support plate 42, and between the second cover plate 49 and the support plate 42, enabling foldable connections between the first cover plate 47 and the support plate 42, and between the second cover plate 49 and the support plate 42. Preferably, the portions of the flexible substrate 41 between the first cover plate 47 and the support plate 42, and between the second cover plate 49 and the support plate 42, are entirely flexible. Optionally, the first cover plate 47, the support plate 42, and the second cover plate 49 are connected to the flexible substrate 41 by bonding or covering. The portions of the flexible substrate 41 corresponding to the first cover plate 47, the support plate 42, and the second cover plate 49 can be made of flexible material or rigid material. Optionally, the flexible substrate 41 is made of a sheath. In other implementations, the flexible substrate 41 may also be made of flexible rubber, silicone, or other flexible materials.

[0149] In other embodiments, the foldable connection structure between the first cover plate 47 and the support plate 42 can also be a hinge structure (not shown in the figure), which connects the support plate 42 and the first cover plate 47. Using a hinge structure can also achieve the foldable connection between the first cover plate 47 and the support plate 42. Similarly, when a second cover plate 49 is provided, the second cover plate 49 and the support plate 42 can also be hinged. This implementation proposes a form of foldable connection between the first cover plate 47 / second cover plate 49 and the support plate 42 via a hinge; the specific hinge structure can be selected and set as needed.

[0150] In one possible implementation, the foldable connection structure between the first cover plate 47 and the support plate 42 is provided with a first flexible connecting strip 52, which connects the support plate 42 and the first cover plate 47. This implementation proposes a foldable connection between the first cover plate 47 and the support plate 42 through the first flexible connecting strip 52; the first flexible connecting strip 52 can be made of leather material, flexible rubber, mesh woven material, etc. The first flexible connecting strip 52 mentioned here can also be the portion of the aforementioned flexible substrate 41 located in the gap between the first cover plate 47 / second cover plate 49 and the support plate 42.

[0151] like Figure 1 or Figure 2 As shown in the diagram, the mobile terminal 20 in this embodiment can also be used in conjunction with the stylus 10. For example... Figure 1 As shown, when the mobile terminal 20 is placed on the support plate 42 and covered by the first cover plate 47, a strip-shaped space 53 is defined between the first flexible connecting strip 52 and the corresponding end face of the mobile terminal 20. The stylus 10 is housed within this strip-shaped space 53. Optionally, a fifth suction member 11 is provided on the stylus 10, and a corresponding fourth suction member 31 is provided on the end face of the mobile terminal 20. Thus, the stylus 10 can be suctioned onto the end face of the mobile terminal 20 when not in use; simultaneously, when it is necessary to store both the mobile terminal 20 and the stylus 10, the stylus 10 can be stored within the aforementioned strip-shaped space 53, making it convenient to use and preventing the stylus 10 from easily falling out or being lost. Optionally, a fourth suction member 67 is fixed on the first flexible connecting strip 52, used to suction onto the corresponding end face of the mobile terminal 20 when the stylus 10 is not housed within the strip-shaped space 53, thereby driving the first flexible connecting strip 52 closer to and adhering to the corresponding end face of the mobile terminal 20. For details, please refer to [link to relevant documentation]. Figure 4 This implementation is compatible with both usage states: when the stylus 10 is stored and when it is not stored. When the stylus 10 is stored, it is housed in the aforementioned strip space 53, supporting the first flexible connecting strip 52 and maintaining its shape. When the stylus 10 is not stored, the fourth suction member 67 is attached to the corresponding end face of the mobile terminal 20, bringing the first flexible connecting strip 52 to fit against the corresponding end face of the mobile terminal 20 and maintaining its shape.

[0152] In another embodiment, the first flexible connecting strip 52 is made of an elastic material (such as elastic rubber) and can be elastically stretched or shortened to adapt to the mobile terminal 20 with or without the stylus 10. In this embodiment, when the stylus 10 is provided, the first flexible connecting strip 52 can be elastically stretched (see...). Figure 1This allows the stylus 10 to be covered; however, when the stylus 10 is not present, the first flexible connecting strip 52 can be shortened to cover the end face of the mobile terminal 20 (see...). Figure 5 In other embodiments, the first flexible connecting strip may be made of a variable elastic material only in the middle section to accommodate the stylus 10; while the sides may be made of a non-elastic material that cannot be stretched or shortened to maintain the distance between the first cover plate 47 and the support plate 42. This arrangement can be referred to in conjunction with [see also...]. Figure 16 The implementation method is shown.

[0153] See you again Figure 1 and Figure 2 In this embodiment, the power connection structure 55 includes a first charging coil 57 and a battery 58. The first charging coil 57 is electrically connected to the battery 58, and the battery 58 is used to supply power to the touchpad 48. Optionally, the touchpad 48 can be located in the middle of the first cover plate 47, with the first charging coil 57 and the battery 58 located on opposite sides of the touchpad 48. The power supply structure 56 includes a second charging coil 59 disposed in the mobile terminal 20; for example, a coil connected to the built-in battery of the mobile terminal 20 can be separately disposed inside the mobile terminal 20 as the second charging coil 59. When the mobile terminal 20 is placed on the support plate 42, the first charging coil 57 and the second charging coil 59 on the first cover plate 47 in the first state correspond to each other in the thickness direction 32 of the mobile terminal 20 to achieve mutual pairing, so that the mobile terminal 20 charges the battery 58 through the pairing of its second charging coil 59 and first charging coil 57. Wireless charging through a coil is based on the principle of electromagnetic induction, which will not be elaborated here. This implementation proposes a structure for wireless charging through a coil. The coil size can be set relatively large and can be completely built into the mobile terminal 20 or the first cover plate 47 without being exposed on the surface, thus not affecting the appearance of the mobile terminal 20 or the first cover plate 47. At the same time, the coil occupies little space in the thickness direction of the structure, but can be easily set to have a large coverage area. Therefore, the relative position requirements of the first charging coil 57 and the second charging coil 59 are low when wireless charging is achieved through the coil. Even if the two are slightly misaligned, normal charging function can still be maintained.

[0154] See also Figure 6 and Figure 7In another implementation, the power connection structure 55 includes a charging Pogo Pin 60 and a battery 58; the charging Pogo Pin 60 is electrically connected to the battery 58, and the battery 58 supplies power to the touchpad 48. The power supply structure 56 includes a charging Pad 61 disposed on the mobile terminal 20. When the mobile terminal 20 is placed on the support plate 42, the charging Pogo Pin 60 on the first cover plate 47 in the first state pairs with the charging Pad 61, so that the mobile terminal 20 charges the battery 58 through the pairing of its charging Pogo Pin 60 and charging Pad 61. This implementation proposes a structure for wireless charging through the cooperation of the charging Pogo Pin 60 and the charging Pad 61. Charging is achieved by pairing the charging Pogo Pin 60 and the charging Pad 61, which is a wired charging method with high charging efficiency. Optionally, the charging Pogo Pin 60 extends vertically out of the surface of the first cover plate 47; the corresponding charging Pad 61 is disposed on the back 22 of the mobile terminal 20. In this implementation, by having the charging Pogo Pin 60 and the charging Pad 61 extend from their respective ground locations, they can be precisely engaged to achieve charging when the first cover plate 47 covers the mobile terminal 20, making it convenient to use.

[0155] See also Figure 8 and Figure 9This embodiment also provides an implementation applicable to the case where the aforementioned mobile terminal base 40 is provided with a foldable second cover plate 49. In this case, the power connection structure 55 includes a charging Pogo Pin 60 and a battery 58; the charging Pogo Pin 60 is electrically connected to the battery 58, and the battery 58 is used to supply power to the touchpad 48; the charging Pogo Pin 60 extends from the side of the first cover plate 47 away from the first side 45 along the plate surface where the first cover plate 47 is located. The power supply structure 56 includes a charging port 62 disposed on the support plate 42, a charging Pad 61 disposed on the side of the second cover plate 49 away from the second side 46, and a flexible circuit board 63 electrically connecting the charging port 62 and the charging Pad 61. When the first cover plate 47 is in its first state and the second cover plate 49 is in its second state, the charging Pogo Pin 60 is paired with the charging Pad 61 so that an external power source (not shown in the figure) connected to the charging port 62 can charge the battery 58 through the pairing of the charging Pad 61 and the charging Pogo Pin 60. In this implementation, a second cover plate 49 is provided. The second cover plate 49 and the aforementioned first cover plate 47 can respectively cover the mobile terminal 20 from both sides, providing further protection and storage for the mobile terminal 20. Furthermore, the charging Pogo Pin 60 of the power connection structure 55 and the charging Pad 61 of the power supply structure 56 are respectively positioned outside the first cover plate 47 and the second cover plate 49. This allows the charging Pogo Pin 60 of the power connection structure 55 and the charging Pad 61 of the power supply structure 56 to electrically engage when the second cover plate 49 and the first cover plate 47 cover the mobile terminal 20, enabling charging of the touchpad 48. In other words, this implementation allows the combination of the first cover plate 47 and the second cover plate 49 to simultaneously provide both storage and protection for the mobile terminal 20 and charging of the touchpad 48 while in a protected state.

[0156] Therefore, in the electronic device 100 provided in this application embodiment, the mobile terminal 20 can be placed on the support plate 42. In the first state, the power connection structure 55 and the power supply structure 56 disposed on the mobile terminal 20 or disposed on the support plate 42 are paired, and the power supply structure 56 supplies power to the touch panel 48 through the power connection structure 55. The mobile terminal base 40 can be used in combination with the mobile terminal 20 to cover and protect the mobile terminal 20. At the same time, when covering the mobile terminal 20, the power supply structure 56 can supply power to the touch panel 48 through the power connection structure 55, so the user does not need to pay extra attention to the battery status of the touch panel 48, making it convenient to use.

[0157] See also Figure 10 and 11The electronic device 100 in one embodiment of this application includes a mobile terminal 20, a stylus 10, and a mobile terminal base 40. The front 21 of the mobile terminal 20 has a screen 23, and the back 22 has a first suction member 28, a second suction member 29, and a third suction member 30 arranged sequentially from bottom 25 to top 26 along its height 24; the top 27 of the mobile terminal 20 has a fourth suction member 31. The side of the stylus 10 has a fifth suction member 11 that matches the fourth suction member 31, for attaching the stylus 10 to the top 27 of the mobile terminal 20. The mobile terminal base 40 includes a flexible substrate 41, a first cover plate 47, a support plate 42, and a second cover plate 49. The first cover plate 47, the support plate 42, and the second cover plate 49 are sequentially and spaced apart from each other on the surface of the flexible substrate 41. The portion of the flexible substrate 41 located between the first cover plate 47 and the support plate 42 is a first flexible connecting strip 52, which allows the first cover plate 47 to be folded 360° relative to the support plate 42. The portion of the flexible substrate 41 located between the second cover plate 49 and the support plate 42 is a second flexible connecting strip 54, which allows the second cover plate 49 to be folded 360° relative to the support plate 42. A keyboard assembly 43 is provided on the side of the support plate 42 near the first cover plate 47. The cover plate 49 has multiple sequentially spaced fixing grooves 44 on one side; the second cover plate 49 includes a second sub-plate 51 and a first sub-plate 50, the second sub-plate 51 and the first sub-plate 50 are respectively connected to the flexible substrate 41, and the first sub-plate 50 and the support plate 42 are spaced apart so that the first sub-plate 50 can be folded relative to the support plate 42, and the second sub-plate 51 and the first sub-plate 50 are spaced apart so that the second sub-plate 51 can be folded relative to the first sub-plate 50; the first sub-plate 50 is provided with a first suction member 64 adapted to the first suction member 28, the second sub-plate 51 is provided with a second suction member 65 adapted to the second suction member 29, the first cover plate 47 is provided with a third suction member 66 adapted to the third suction member 30, and the first flexible connecting strip 52 is provided with a fourth suction member 67 adapted to the fourth suction member 31. The distance h1 between the first attracting member 28 and the second attracting member 29 in the height direction 24 of the mobile terminal 20 is substantially equal to the distance h2 between the first attracting member 64 and the second attracting member 65 in the direction from the first sub-plate 50 to the second sub-plate 51. The mobile terminal base 40 also includes a touch panel 48 and a power connection structure 55; the touch panel 48 is disposed on the first cover plate 47; the power connection structure 55 is disposed on the first cover plate 47 and electrically connected to the touch panel 48. When the first cover plate 47 is folded over to cover the mobile terminal 20 placed on the support plate 42, the power connection structure 55 and the power supply structure 56 disposed on the mobile terminal 20 or on the support plate 42 are paired, so that the power supply structure 56 supplies power to the touch panel 48 through the power connection structure 55. Figure 10 and Figure 11 In the embodiment shown, the structure for supplying power to the touchpad 48 is as described above. Figure 1and Figure 2 The embodiment shown is powered by a charging coil; of course, the same implementation can also adopt the aforementioned method. Figure 6 and Figure 7 or Figure 8 and Figure 9 The method shown involves power supply via the charging Pogo Pin 60 and the charging Pad 61, which will not be described in detail here.

[0158] In this embodiment, the first attracting member 64, the second attracting member 65, the third attracting member 66, the fourth attracting member 67, and the fifth attracting member 11 can all be made of magnets; similarly, the first attracted member 28, the second attracted member 29, the third attracted member 30, and the fourth attracted member 31 can also be made of magnets, as long as they can correspond and attract each other. Each attracting member can be provided in one or more forms. As shown in the figure, each attracting member and attracted member is provided in pairs, spaced apart from each other. Providing two of each attracting member improves the reliability of the attraction.

[0159] It should be noted that, without conflict, all additional defining features of the electronic device 100 in this embodiment can be used for Figures 1-9 The various embodiments shown.

[0160] The electronic device 100 is used in any of the following combinations of states:

[0161] First combined state: The mobile terminal 20 is detached from the mobile terminal base 40 and can be used alone or in conjunction with the stylus 10; in this combined state, the stylus 10 can be attracted to the fourth attracted part 31 on the top surface 27 of the mobile terminal 20 via the fifth attracted part 11; this combined state can be seen in [reference needed]. Figure 11 ;

[0162] Second combined state: The first cover plate 47 and the second cover plate 49 of the mobile terminal base 40 are unfolded relative to the support plate 42, the screen 23 of the mobile terminal 20 is stacked on the second cover plate 49 with its screen facing upward, and the first suction member 28 on its back 22 is correspondingly suctioned to the first suction member 64, and the second suction member 29 is correspondingly suctioned to the second suction member 65; since the distance h1 between the first suction member 28 and the second suction member 29 in the height direction 24 of the mobile terminal 20 is basically equal to the distance h2 between the first suction member 64 and the second suction member 65 in the direction from the first sub-plate 50 to the second sub-plate 51, it is possible to simultaneously satisfy the states of the first suction member 64 and the first suction member 28 corresponding and the second suction member 65 and the second suction member 29 corresponding; this combined state can be referred to Figure 12 ;

[0163] Third combined state: The support plate 42 is placed horizontally, the first sub-plate 50 is tilted upwards and forms an acute angle with the support plate 42; the mobile terminal 20 is supported by the first sub-plate 50 at an overall tilt, and the back 22 of the mobile terminal 20 is attached to the second sub-plate 51 and its second suction member 29 suctions the second suction member 65 of the second sub-plate 51, and the bottom edge of the mobile terminal 20 is located at one of the fixing slots 44; the stylus 10 is held for use or suctioned onto the top surface 27 of the mobile terminal 20; this combined state can be seen in [reference needed]. Figure 13 ;

[0164] Fourth combined state: The screen 23 of the mobile terminal 20 is stacked on the second cover plate 49 with its screen facing upwards, and the first suction member 28 on its back 22 is correspondingly suctioned to the first suction member 64, and the second suction member 29 is correspondingly suctioned to the second suction member 65; the support plate 42 is folded to the side of the second cover plate 49 away from the mobile terminal 20 and adheres to the second cover plate 49, and the first cover plate 47 is folded to adhere to the side of the support plate 42 away from the mobile terminal 20; the realization of this combined state also benefits from the aforementioned setting that the distance h1 between the first suction member 28 and the second suction member 29 in the height direction 24 of the mobile terminal 20 is basically equal to the distance h2 between the first suction member 64 and the second suction member 65 in the direction from the first sub-plate 50 to the second sub-plate 51; this combined state can be seen in [reference needed]. Figure 14 ;

[0165] Fifth combined state: The mobile terminal 20 is placed on the support plate 42 with its top surface 27 facing the first cover plate 47 and its back surface 22 facing upwards; the first cover plate 47 is flipped to cover the back surface 22 of the mobile terminal 20, and its third suction member 66 is suctioned to the third suction member 30 on the back surface 22 of the mobile terminal 20; the second cover plate 49 is flipped to cover the back surface 22 of the mobile terminal 20, and its first suction member 64 is correspondingly suctioned to the first suction member 28 on the back surface 22 of the mobile terminal 20, and its third suction member 66 is suctioned to the third suction member 30 ...30 is suctioned to the third suction member 30 on the back surface 22 of the mobile terminal 20, and its third suction member 30 is suctioned to the third suction member 30 on the back surface 22 of the mobile terminal 20, and its third suction member 30 is suctioned to the third suction member 30 on the back surface 22 of the mobile terminal 20, and its third suction member 30 is suctioned to the third suction member 30 on the back surface 22 of the mobile terminal 20, and its third suction The second suction member 65 on the mobile terminal 20 is correspondingly suctioned to the second suction member 29 on the back 22 of the mobile terminal 20; the realization of this combination state also benefits from the fact that the distance h1 between the first suction member 28 and the second suction member 29 in the height direction 24 of the mobile terminal 20 is basically equal to the distance h2 between the first suction member 64 and the second suction member 65 in the direction from the first sub-board 50 to the second sub-board 51; in the fifth combination state, the power supply structure 56 supplies power to the touch panel 48 through the power connection structure 55; this combination state can be seen in Figure 10 .

[0166] Furthermore, in all five combined states mentioned above, the stylus 10 can be attracted to the fourth attracted component 31 of the mobile terminal 20 via its fifth attracting member 11, and can also be detached from the mobile terminal 20. In the fifth combined state, when the stylus 10 is detached from the mobile terminal 20, the fourth attracting member 67 on the mobile terminal base 40 attracts the fourth attracted component 31 on the mobile terminal 20, as can be seen from [the following description is missing from the original text]. Figure 15 .

[0167] See Figure 16 This application also provides an electronic device 100, including a mobile terminal 20 and a mobile terminal base 40.

[0168] The mobile terminal base 40 includes a support plate 42, a first cover plate 47, and a touch panel 48, with the touch panel 48 disposed on the first cover plate 47. The support plate 42 has a first side 45, and the first cover plate 47 is foldably connected to the first side 45 of the support plate 42 via a first flexible connecting strip 52. The first flexible connecting strip 52 includes an elastic region 81 and a non-elastic region 82 arranged sequentially along a direction parallel to the first side 45. The elastic region 81 can be elastically stretched or shortened to accommodate the placement or non-placement of the stylus 10; the non-elastic region 82 cannot be stretched or shortened. A main battery 84 is provided at the support plate 42, and the main battery 84 is electrically connected to the touch panel 48 via a flexible circuit board 83 to supply power to the touch panel 48. The flexible circuit board 83 extends from the non-elastic region 82 through the first flexible connecting strip 52. The mobile terminal 20 can be placed on the support plate 42 and covered by the first cover plate 47. Meanwhile, the touch panel 48 disposed on the first cover plate 47 can be powered by the flexible circuit board 83 passing through the non-elastic area 82 of the first flexible connecting strip 52.

[0169] In the mobile terminal base 40 and electronic device 100 of this application embodiment, the touchpad 48 is disposed on the first cover plate 47 which is foldably connected to the support plate 42, without occupying space on the support plate 42, thus providing more space on the support plate 42 for placing the keyboard or other structures; furthermore, by setting the first flexible connecting strip 52 to distinguish the elastic area 81 and the non-elastic area 82, the flexible circuit board 83 passes through the first flexible connecting strip 52 from the non-elastic area 82, which can prevent the flexible circuit board 83 from being stretched and damaged in that area; the elastic area 81 can be used to accommodate the situation of storing or not storing the stylus 10. This structure and function design is reasonable and convenient to use.

[0170] In one possible implementation, the mobile terminal base 40 further includes a second cover plate 49. The second cover plate 49 is connected to the second side 46 of the support plate 42 opposite to its first side 45 via a second flexible connecting strip 54, and the second cover plate 49 can be folded relative to the support plate 42. This implementation, with the first cover plate 47 and the second cover plate 49, can respectively cover the mobile terminal 20 placed on the support plate 42 from both sides. It has a simple structure, is easy to use, and can reliably protect the mobile terminal 20.

[0171] In one possible implementation, the middle portion of the first flexible connecting strip 52 is designated as an elastic region 81, and the two sides are designated as non-elastic regions 82. The length of the elastic region 81 is adapted to the length of the stylus 10, for example, it can be set to be slightly longer than the length of the stylus 10.
