Description

Electronic devices and keyboards

[0001] This application claims priority to Chinese Patent Application No. 202510068765.7, filed on January 15, 2025, entitled “Electronic Device and Keyboard”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronics, specifically to an electronic device and a keyboard. Background Technology

[0003] Terminal devices such as computers have become indispensable tools for consumers in their daily lives and work. Laptops have keyboards, which provide strong input interactivity, while tablets offer better convenience. Combining the features of both for personal or office use has become a trend.

[0004] Typically, the keyboard is attached to the back of the tablet computer via a stand. To ensure the tablet is held at a certain angle and height for easy use, the stand design is complex and heavy, making it inconvenient for users to carry and limiting the device's flexibility. Summary of the Invention

[0005] Embodiments of this application provide an electronic device and a keyboard that can reduce the weight of the electronic device, thereby providing users with a better user experience.

[0006] In a first aspect, this application provides an electronic device, including a keyboard and a host. The keyboard includes a keyboard body and a keyboard stand, which are rotatably connected to the keyboard body.

[0007] The host includes a host body and a host stand. The host body includes a display surface and a non-display surface, which are arranged opposite to each other. The non-display surface includes a first area and a second area connected to the first area. The host stand is rotatably connected to the non-display surface. The host stand and the keyboard stand are detachably connected. The keyboard stand is located on the side of the host stand away from the host body.

[0008] When the electronic device is folded, the main unit stand is stacked in the first area, the keyboard stand is stacked on top of the main unit stand, and the main unit and keyboard are stacked on top of each other. Both the keyboard stand and the main unit stand are located on the side of the main unit that faces away from the keyboard. The second area is exposed relative to the keyboard stand. When the electronic device is unfolded, the keyboard stand and keyboard are at an angle, and the main unit stand and main unit are at an angle.

[0009] The keyboard stand is defined as being at an angle to the keyboard body, with the keyboard stand open relative to the keyboard body, and the angle between the keyboard stand and the keyboard body being greater than 0°. Similarly, the host stand is defined as being at an angle to the host body, with the host stand open relative to the host body, and the angle between the host stand and the host body being greater than 0°.

[0010] The second area of ​​the main unit is the back of the main unit that protrudes from the main unit stand. In this embodiment, the keyboard stand is connected to the main unit stand. The keyboard stand only covers a portion of the main unit's surface. Compared to commonly used electronic devices where the keyboard stand covers the entire surface of the main unit, the keyboard stand of this application is smaller, which is beneficial for the miniaturization and weight reduction of the keyboard. The miniaturized and lightweight keyboard makes it more convenient to carry. When going out or traveling, users can easily put the keyboard into a backpack or handbag without adding too much weight or taking up too much space.

[0011] Only a portion of the host's surface (the first area, excluding the display surface) is covered by the keyboard stand, while the remaining portion of the host's surface is exposed relative to the keyboard stand. This creates a difference from the form of existing electronic devices, allowing users to experience a unique appearance and enhancing their user experience.

[0012] In one possible implementation, the keyboard includes a first hinge assembly, and the keyboard bracket includes a keyboard connection part and a host connection part. The keyboard connection part is rotatably connected to the keyboard body via the first hinge assembly, and the host connection part is connected to the side of the keyboard connection part away from the keyboard body. The host connection part can be detachably connected to the host bracket.

[0013] The keyboard connector is provided with a first pen groove, which is recessed toward the surface of the keyboard body when the keyboard is folded.

[0014] In this embodiment, the host and the keyboard connector together cover the keyboard body. The width of the keyboard body can be the same as or similar to the sum of the width of the keyboard connector and the width of the host. Therefore, the keyboard connector allows for an increase in the width of the keyboard body. Increasing the area of ​​the keyboard body increases the contact area between the keyboard body and the supporting surface. A larger contact area provides more stable support for the electronic device, helping to prevent slippage or tipping due to accidental touch or movement during use, thus protecting the electronic device from damage.

[0015] Increasing the width of the keyboard allows for a larger area to accommodate keycaps and a touchpad. Larger keycaps in electronic devices result in larger, more evenly spaced keys with a more traditional layout, making them easier for users with specific key preferences to operate and effectively reducing accidental keystrokes and typing fatigue. The increased keyboard area also typically means more reasonable spacing between adjacent keys, which helps users type more accurately, thus improving typing speed and accuracy.

[0016] A larger touchpad means a larger operating area for the user, making it easier to perform various gesture operations such as swiping, zooming, and rotating, thus improving the convenience and flexibility of operation. When handling editing tasks or dragging and dropping files, a larger touchpad can provide a smoother and more efficient operating experience.

[0017] In one possible implementation, the keyboard body further includes a second pen slot, which is recessed into the surface of the keyboard body facing the keyboard support. When the keyboard support is in the closed state, the second pen slot is opposite to the first pen slot.

[0018] In this embodiment, when the keyboard stand is closed, the second pen slot and the first pen slot together form a space for the stylus. When the keyboard stand is open, the second pen slot moves away from the first pen slot, exposing the stylus for easy access by the user. After use, the user can directly place the stylus in the second pen slot without any further alignment, simplifying the user's operation. When the user closes the keyboard stand, the walls of the first and second pen slots automatically align to restrain the stylus, preventing it from falling off the keyboard.

[0019] In one possible implementation, the keyboard is provided with a charging port, which is located on the side of the keyboard connector, or the charging port is located on the side of the keyboard body.

[0020] In this embodiment, the charging port is located on the side of the keyboard connector or on the side of the keyboard body, which makes the charging position of the electronic device similar to that of a laptop computer. This design allows users of the electronic device provided in this application to adapt more quickly and reduces operational inconvenience caused by different charging positions.

[0021] In one possible implementation, when the electronic device is in the unfolded state, the end face of the keyboard connector facing away from the host connector protrudes from the bottom face of the keyboard body facing away from the host. The end face of the keyboard connector facing away from the host connector can be used to abut against the bearing surface of the electronic device.

[0022] The surface used to support the electronic device can be a desktop or tabletop, etc.

[0023] In this embodiment, when the keyboard stand is in the open state, the keyboard connection portion of the keyboard stand can directly abut against the flat surface on which it is placed. The flat surface at the placement point can directly provide support to the keyboard stand, thereby making the host connected to the keyboard stand less prone to shaking, reducing the impact of host shaking on the keyboard body, and preventing the center of gravity of the electronic device from shifting away from the keyboard body when the user touches the host, thus avoiding the electronic device tipping over, and improving the stability of the electronic device.

[0024] In one possible implementation, the first hinge assembly includes at least two torque units, which are spaced apart. Each torque unit is connected between the keyboard bracket and the keyboard body, and the multiple torque units distribute the torque of the first hinge assembly into multiple torque ranges.

[0025] In one possible implementation, the torque unit includes a spindle, a first fixing member, and a second fixing member. Both the first fixing member and the second fixing member are sleeved on the spindle. The first fixing member can rotate relative to the spindle, and the rotation of the second fixing member relative to the first fixing member can drive the spindle to rotate. The first fixing member is fixedly connected to the keyboard body, and the second fixing member is fixedly connected to the keyboard bracket.

[0026] In this embodiment, the hinge between the keyboard bracket and the keyboard body transforms a single torque range into multiple smaller torque ranges. That is, the keyboard bracket and keyboard body are connected via multiple torque units. This distributes the torque between the keyboard bracket and keyboard body into multiple small torques. This reduces the torque borne by each individual torque unit, allowing for a smaller size of the torque unit and thus reducing the installation space it occupies on the keyboard. This results in a simpler keyboard design and contributes to overall keyboard miniaturization.

[0027] In one possible implementation, the torque unit further includes a cam sleeved on a spindle. Rotation of the cam relative to the first fixing member can drive the spindle to rotate. The cam is fitted into the first fixing member. The first fixing member has a first recess and a second recess, both recessed on the end face of the first fixing member facing the cam.

[0028] The cam has a first protrusion, which protrudes from the end face of the cam facing the first fixing member.

[0029] When the keyboard stand is in the closed state, the first protrusion is located in the first recess. When the keyboard stand is opened, the first protrusion can slide out from the first recess and slide into the second recess, so that the keyboard stand is in the open state.

[0030] In this embodiment, when the first protrusion automatically slides into the second recess, the keyboard stand automatically opens. Users do not need to manually adjust the opening angle of the keyboard stand to quickly reach a suitable usage state, greatly improving ease of use. Automatically opening to the optimal angle for use reduces improper host angle caused by an incorrect keyboard stand angle, avoiding visual fatigue or uncomfortable hand operation angles due to host angle issues.

[0031] In one possible implementation, the first protrusion includes a first abutting surface, a second abutting surface, and a connecting surface. The first abutting surface and the second abutting surface are respectively connected to opposite sides of the connecting surface. The angle between the first abutting surface and the connecting surface is greater than the angle between the second abutting surface and the connecting surface.

[0032] The first recess includes a first sidewall, a second sidewall, and a first bottom wall. The first sidewall and the second sidewall are connected to opposite sides of the first bottom wall. The angle between the first sidewall and the first bottom wall is greater than the angle between the second sidewall and the first bottom wall.

[0033] The second recess includes a third sidewall, a fourth sidewall, and a second bottom wall. The third sidewall and the fourth sidewall are connected to opposite sides of the second bottom wall. The angle between the third sidewall and the second bottom wall is greater than the angle between the fourth sidewall and the second bottom wall.

[0034] When the keyboard stand is opened, the first protrusion slides out of the first recess, the second abutting surface slides along the second side wall, so that the first protrusion slides out of the first recess, the first protrusion slides into the second recess, and the first abutting surface of the first protrusion slides along the third side wall, so that the first protrusion is located in the second recess.

[0035] In this embodiment, when the first protrusion slides out of the first recess, the second abutment surface slides along the second sidewall. Since the angle between the second sidewall and the first bottom wall is small, the torque unit has a small torque. This allows the keyboard bracket to open before the main unit bracket when subjected to external force. When the first protrusion slides out of the second recess, the first abutment surface slides along the third sidewall. Since the angle between the third sidewall and the second bottom wall is large, the torque unit has a large torque. This allows the main unit bracket to close before the keyboard bracket when subjected to external force. Ultimately, this allows the electronic device to operate sequentially during opening and closing.

[0036] In one possible implementation, the torque unit further includes a friction plate sleeved on a spindle. Rotation of the spindle can drive the friction plate to rotate, and the friction plate applies an elastic force to the cam so that the cam abuts against the first fixing member.

[0037] In one possible implementation, the first rotating shaft further includes a fastener, which is sleeved on the spindle and located on the side of the friction plate away from the cam. The fastener is fixedly connected to the end of the spindle.

[0038] In this embodiment, the fastener can fix the cam, fastening plate, friction plate, etc. on the mandrel to prevent the cam, fastening plate, friction plate, etc. from falling off the mandrel.

[0039] In one possible implementation, the first rotating shaft assembly further includes a connecting sleeve, wherein the two spindles of two adjacent torque units are fixedly connected by the connecting sleeve, and rotation of any spindle can drive the connecting sleeve to rotate.

[0040] In this embodiment, the connecting sleeve can fix the two spindles together, allowing them to rotate coaxially with the same rotation angle. This ensures that the opening angle is the same at different positions of the keyboard bracket, improving the reliability of the keyboard bracket opening.

[0041] In one possible implementation, the main unit also includes a mid-frame and a stop assembly. One end of the stop assembly is connected to the mid-frame, and the other end is connected to the main unit bracket. The stop assembly can prevent the angle between the main unit bracket and the mid-frame from increasing further when the main unit bracket is opened to a certain angle.

[0042] In one possible implementation, the stop assembly includes a first fixed seat, a second fixed seat, a slider, and a stop block. The stop block is connected to the first fixed seat, the slider is slidably connected to the first fixed seat, and the second fixed seat is rotatably connected to the slider. The first fixed seat is connected to the main support bracket, and the second fixed seat is connected to the middle frame. When the main support bracket is in the closed state, the stop block is located outside the sliding path of the slider; when the main support bracket is in the open state, the stop block is located within the sliding path of the slider.

[0043] In this embodiment, when the main unit bracket is opened to a certain angle, the stop block can move into the sliding path of the slider to block the slider from continuing to slide, thereby stopping the relative position of the first fixed seat and the second fixed seat from changing, and thus keeping the main unit bracket and the main unit body at a certain angle for user convenience.

[0044] In one possible implementation, the keyboard bracket is provided with a first magnetic element, and the stop block is provided with a second magnetic element. The first mounting base has a sliding groove and a stop block through-slot. The sliding groove is recessed from the surface of the first mounting base away from the host bracket and extends in the width direction of the host bracket. The stop block through-slot penetrates the first mounting base along its thickness direction and communicates with the sliding groove. The stop block is connected to the side of the first mounting base facing the host bracket. Under the repulsive force of the first magnetic element, the second magnetic element can drive the stop block through the stop block through-slot, so that at least a portion of the stop block is located within the sliding groove.

[0045] In one possible implementation, the stop assembly further includes an elastic element and a connecting rod. The elastic element abuts against the stop block and the first fixed seat. The second magnetic element can drive the stop block to move away from the first magnetic element under the repulsive force of the first magnetic element and compress the elastic element.

[0046] With the keyboard stand and the host stand detached, the elastic element drives the stop block to move toward the host stand, so that the stop block is outside the slide groove.

[0047] With the keyboard stand and the host stand detached, the elastic element drives the stop block to move toward the host stand, so that the stop block is outside the slide groove.

[0048] One end of the connecting rod is rotatably connected to the slider, and the other end of the connecting rod is rotatably connected to the second fixed component.

[0049] In this embodiment, after the host and keyboard stand are separated, the magnetic component of the keyboard stand moves away from the host. Therefore, the magnetic component of the stop assembly on the host is not subject to the repulsive force of the magnetic component of the keyboard stand. Under the action of the elastic component, the stop block is lifted from the stop block through groove of the first fixed seat. At this time, the slider can slide freely along the slide groove of the first fixed seat, so that the host stand can continue to open to a larger angle relative to the host body.

[0050] In one possible implementation, the host body is provided with a third magnetic element, and the keyboard bracket is provided with a fourth magnetic element.

[0051] When the host stand is in the closed state, the host body, host stand and keyboard stand are stacked, and there is magnetic attraction between the third magnetic component and the fourth magnetic component. The distance between the third magnetic component and the fourth magnetic component is the first distance.

[0052] When the host bracket is in the open state, the host body and the host bracket are at an angle, and the third magnetic component and the fourth magnetic component have a second distance, which is greater than the first distance.

[0053] In this embodiment, when the host stand is in the open state, the magnetic force between the fourth magnetic component of the keyboard stand and the third magnetic component of the host body is relatively small. Therefore, the connection force between the host and the keyboard is also relatively small under external force. The magnetic attraction between the host and the keyboard stand is less than the magnetic attraction between the host and the keyboard when the host stand is in the open state. Thus, the host of the electronic device can be detached from the keyboard stand with a smaller external force, allowing the user to use the host independently.

[0054] In one possible implementation, the host body is provided with a fifth magnetic element, which is connected to the edge of the host body.

[0055] The main unit bracket is equipped with a sixth magnetic component, which is connected to the edge of the main unit bracket. When the main unit bracket is in the closed state, there is a magnetic attraction between the sixth magnetic component and the fifth magnetic component, and the distance between the sixth magnetic component and the fifth magnetic component is the third distance. When the main unit bracket is in the open state, the distance between the sixth magnetic component and the fifth magnetic component is the fourth distance, which is greater than the third distance.

[0056] In this embodiment, when the main unit and the main unit stand are closed, the fifth magnetic component of the main unit and the sixth magnetic component of the main unit stand are at least partially opposite each other. At this time, the fifth and sixth magnetic components attract each other, so that the main unit stand and the main unit can be kept in a closed state, thereby facilitating the user to use the main unit alone.

[0057] In one possible implementation, the host stand is equipped with a seventh magnetic element, which is connected to the middle area of ​​the host body's frame. The seventh magnetic element is spaced apart from the sixth magnetic element along the width of the host stand. The host stand and the keyboard stand are connected by the magnetic attraction between the seventh magnetic element and the first magnetic element.

[0058] The keyboard stand has an eighth magnetic component, which is connected to the side of the keyboard stand's main unit connection facing the keyboard connection. The main unit stand is connected to the keyboard stand, and the eighth magnetic component has a magnetic attraction with the sixth magnetic component.

[0059] In this embodiment, the keyboard stand and the host stand can be magnetically attracted by the eighth magnetic component and the sixth magnetic component to connect the host and the keyboard.

[0060] In one possible implementation, the electronic device includes an initial state and a first state. In the initial state, both the keyboard stand and the host stand are in a closed state. In the first state, the keyboard stand is in an open state and the host stand is in a closed state.

[0061] During the process of an electronic device transitioning from its initial state to its first state, Fa, Fb, Fc, L, M1, and M2 satisfy the following relationship.

[0062] Fb*L+M2>M1, Fc*L+M2>M1, Fb>Fc.

[0063] Among them, the sum of the magnetic attraction forces of the fourth magnetic component and the third magnetic component, and the first magnetic component and the seventh magnetic component is Fa; the magnetic attraction force of the eighth magnetic component and the sixth magnetic component is Fb; the sum of the magnetic attraction forces of the fifth magnetic component and the sixth magnetic component is Fc; the opening torque of the keyboard stand is M1; the opening torque of the host stand is M2; and the width of the host stand is L.

[0064] In this embodiment, during the transition of the electronic device from the initial state to the first state, the keyboard bracket rotates relative to the keyboard body, causing the second fixing member of the torque unit to rotate relative to the first fixing member. Since Fc*L+M2>M1, the main unit bracket does not rotate during the normal rotation of the keyboard bracket. This prevents the main unit from accidentally opening and impacting the keyboard body.

[0065] In one possible implementation, the electronic device further includes a second state in which both the keyboard stand and the main unit stand are in the open state. During the transition from the first state to the second state, Fb, Fc, L, and M2 satisfy the following relationships: Fb*L > M2, Fb*L > M2 + Fc*L.

[0066] In this embodiment, when the host stand is opened, since Fb*L>M2+Fc*L and Fb*L>M2, the force exerted on the host stand during the opening process will not exceed the magnetic attraction between the host stand and the keyboard stand. Therefore, the host stand will not separate from the keyboard stand during the opening process, thus preventing the host from falling off during normal opening.

[0067] In one possible implementation, during the transition of the electronic device from the second state to the first state, Fb, L, and M2' satisfy the following relationship: M2' < Fa*L. Wherein, the torque required to close the main unit bracket is M2'.

[0068] In this embodiment, during the transition of the electronic device from the second state to the first state, due to the large torque required to close the keyboard bracket, the angle between the main unit and the main unit bracket gradually decreases under the action of external force, thus keeping the main unit bracket in a closed state. Furthermore, during the closing process of the main unit bracket, Fa needs to be sufficiently large to prevent the main unit from detaching from the keyboard bracket under external force.

[0069] In one possible implementation, during the transition of the electronic device from a first state to an initial state, Fa, L, and M1' satisfy the following relationship: M1' < Fa * L. Wherein, the torque required to close the keyboard bracket is M1'.

[0070] In this embodiment, as the electronic device changes from the first turntable to its initial state, the angle between the keyboard bracket and the keyboard body gradually decreases under the continued action of external force, so that the keyboard body is in a closed state. Furthermore, during the closing process of the keyboard bracket, Fa needs to be large enough to prevent the host from detaching from the keyboard bracket under the action of external force.

[0071] In one possible implementation, the keyboard also includes a hinge cover and a first hinge assembly.

[0072] The keyboard body is provided with a first hinge receiving groove, which is recessed from the end face of the keyboard body toward the keyboard bracket and extends to two opposite surfaces of the keyboard body along a first direction.

[0073] The keyboard bracket is provided with a second hinge receiving groove, which is recessed from the end face of the keyboard bracket toward the keyboard body and extends to two opposite surfaces of the keyboard bracket along a first direction.

[0074] The first hinge receiving groove and the second hinge receiving groove are connected to form a receiving space. The first hinge assembly is located in the receiving space. The hinge cover is connected to the keyboard bracket and covers the openings of the first hinge receiving groove and the second hinge receiving groove.

[0075] In this embodiment, the surface of the hinge cover facing away from the first hinge assembly can be the keyboard's exterior surface facing the X direction. The exterior surface of the keyboard facing away from the X direction is simpler, thereby improving the overall aesthetics and visual harmony of the keyboard.

[0076] In one possible implementation, the keyboard further includes a keyboard support connector, a keyboard body connector, and a torque unit. The keyboard support connector is fixedly connected to the keyboard support, the keyboard body connector is fixedly connected to the keyboard body, and the torque unit is connected between the keyboard support connector and the keyboard body connector to enable the keyboard support connector to rotate relative to the keyboard body connector.

[0077] In one possible implementation, the keyboard further includes a pen slot cover, and the keyboard body connector is provided with a pen slot, which is recessed on the side of the keyboard body connector away from the keyboard body and extends along a first direction.

[0078] The keyboard support connector includes two hinge housings located at both ends of the keyboard body connector along a first direction, and a torque unit is connected between the hinge housings and the end faces of the keyboard body connector.

[0079] The pen slot cover is located between the two hinge housings. The pen slot cover is detachably connected to the keyboard body connector and covers the opening of the pen slot.

[0080] In this embodiment, when the electronic device is off, the pen slot cover can be opened from the outer surface of the keyboard hinge area to allow for pen access. The pen slot cover and the hinge housing can form an integrated appearance structure. This allows for a differentiated appearance at the keyboard hinge position, which often enhances the overall aesthetics of the keyboard and provides a better visual experience for the user.

[0081] Secondly, this application also provides a keyboard, including the keyboard described above.

[0082] Thirdly, this application also provides a keyboard, including a keyboard body, a first hinge assembly and a keyboard bracket, wherein the keyboard body is rotatably connected to the keyboard bracket through the first hinge assembly;

[0083] The keyboard body has a key group and a touchpad on its surface. The touchpad is located on the side of the key group away from the first hinge assembly. The width of the keyboard bracket is smaller than the width of the keyboard body. The width of the keyboard is perpendicular to the axis of the first hinge assembly. When the keyboard bracket is in the closed state, the keyboard bracket is stacked on top of the keyboard body. At least part of the key group is covered by the keyboard bracket, and at least part of the touchpad is exposed relative to the keyboard bracket.

[0084] In this embodiment, since keyboards for general electronic devices are frequently carried or moved, a smaller keyboard stand structure means the entire keyboard is more compact and lightweight, making it easier for users to carry. The reduced size of the keyboard stand helps to reduce the overall weight of the keyboard. Lighter weight reduces the burden on the user during use and improves comfort during extended use.

[0085] A smaller keyboard stand takes up less space when stored or carried. For example, the compact keyboard design makes it easier to fit into a backpack or handbag when traveling or commuting.

[0086] In one possible implementation, the keyboard further includes a first hinge assembly, and the keyboard bracket includes a keyboard connection part and a host connection part. The keyboard connection part is rotatably connected to the keyboard body through the first hinge assembly, and the host connection part is connected to the side of the keyboard connection part away from the keyboard body.

[0087] The keyboard connector is provided with a first pen groove, which is recessed toward the surface of the keyboard body when the keyboard is folded.

[0088] In one possible implementation, the keyboard body is further provided with a second pen slot, which is recessed from the surface of the keyboard body toward the keyboard support.

[0089] When the keyboard stand is closed, the second pen slot is opposite to the first pen slot.

[0090] In one possible implementation, when the keyboard stand is in the open state, the end face of the keyboard connector facing away from the host connector protrudes from the bottom face of the keyboard body facing away from the host. The end face of the keyboard connector facing away from the host connector can be used to abut against the support surface that carries the keyboard.

[0091] In one possible implementation, the first shaft assembly includes at least two torque units, which are spaced apart.

[0092] Each torque unit includes a spindle, a first fixing member, and a second fixing member. Both the first fixing member and the second fixing member are sleeved on the spindle. The first fixing member can rotate relative to the spindle, and the second fixing member can rotate relative to the first fixing member to drive the spindle to rotate. The first fixing member is fixedly connected to the keyboard body, and the second fixing member is fixedly connected to the keyboard bracket.

[0093] In one possible implementation, the torque unit further includes a cam, which is sleeved on the spindle. The rotation of the cam relative to the first fixing member can drive the spindle to rotate. The cam is fitted to the first fixing member.

[0094] The first fixing member has a first recess and a second recess, which are recessed on the end face of the first fixing member facing the cam.

[0095] The cam has a first protrusion, which protrudes from the end face of the cam facing the first fixing member;

[0096] When the keyboard stand is in the closed state, the first protrusion is located in the first recess. When the keyboard stand is opened, the first protrusion can slide out from the first recess and slide into the second recess, so that the keyboard stand is in the open state.

[0097] In one possible implementation, the first protrusion includes a first abutting surface, a second abutting surface, and a connecting surface. The first abutting surface and the second abutting surface are respectively connected to opposite sides of the connecting surface. The angle between the first abutting surface and the connecting surface is greater than the angle between the second abutting surface and the connecting surface.

[0098] The first recess includes a first sidewall, a second sidewall, and a first bottom wall. The first sidewall and the second sidewall are connected to opposite sides of the first bottom wall. The angle between the first sidewall and the first bottom wall is greater than the angle between the second sidewall and the first bottom wall.

[0099] The second recess includes a third sidewall, a fourth sidewall, and a second bottom wall. The third sidewall and the fourth sidewall are connected to opposite sides of the second bottom wall. The angle between the third sidewall and the second bottom wall is greater than the angle between the fourth sidewall and the second bottom wall.

[0100] When the keyboard stand is opened, the first protrusion slides out of the first recess, the second abutting surface slides along the second side wall, so that the first protrusion slides out of the first recess, the first protrusion slides into the second recess, and the first abutting surface of the first protrusion slides along the third side wall, so that the first protrusion is located in the second recess.

[0149] The specific embodiments of this application will now be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in other ways different from those described herein, and therefore, this application is not limited to these embodiments.

[0150] For ease of understanding, the terminology used in the embodiments of this application will be explained first.

[0151] Multiple: refers to two or more.

[0152] Connection: should be interpreted broadly. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through an intermediary.

[0153] Along a certain direction: This includes the described situation and situations similar to the described situation, where the range of similar situations is within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "vertical" includes absolute vertical and approximately vertical, where the acceptable deviation range for approximately vertical can also be, for example, a deviation within 5°.

[0154] The specific embodiments of this application will now be clearly described in conjunction with the accompanying drawings.

[0155] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the electronic device 100 provided in this embodiment in a folded state. Figure 2 is a schematic diagram of the electronic device 100 shown in Figure 1 in an open state. In these figures, the X direction represents the width direction of the electronic device 100, the Y direction represents the length direction of the electronic device 100, and the Z direction represents the thickness direction (height direction) of the electronic device 100. It should be noted that the directional descriptions of each part of the electronic device 100 in the following text are based on the X, Y, and Z directions in Figure 1. That is, the overall description of the electronic device 100 and the descriptions of each part of its structure are based on the electronic device 100 in a closed state.

[0156] In this design, electronic device 100 can be a tablet computer. For example, electronic device 100 can be a detachable 2-in-1 tablet computer. The practicality of a 2-in-1 tablet computer lies in the user's ability to freely switch between computer and tablet modes, quickly transitioning between computer and tablet states. The computer can primarily serve as an office tool, while the tablet can primarily be used for entertainment. When electronic device 100 is folded to the state shown in Figure 1, it is thin and small, making it easy for users to carry.

[0157] Electronic device 100 includes a main unit 10 and a keyboard 20. The main unit 10 and the keyboard 20 can be detached or connected at any time. When the main unit 10 and the keyboard 20 are connected, a connection structure is needed to enable power supply and signal transmission between the main unit 10 and the keyboard 20. The connection structure typically needs to meet requirements such as easy plugging and unplugging and stable signal transmission.

[0158] As shown in Figure 1, the electronic device 100 is in the off state, with the host 10 and keyboard 20 closed. A portion of the non-display surface of the host 10 is covered by the keyboard bracket of the keyboard 20, while the remaining portion of the non-display surface of the host 10 is exposed relative to the keyboard bracket of the keyboard 20.

[0159] As shown in Figure 2, the electronic device 100 is in the open state, and the host 10 is opened to a certain angle relative to the keyboard 20. This angle can be a right angle, an acute angle, or an obtuse angle, and can be flexibly adjusted according to the user's angle.

[0160] In existing technologies, the keyboard is typically integrated with the tablet by attaching a stand to the entire back of the tablet. To ensure the tablet maintains a certain angle and height for convenient use when open, the stand structure is complex and heavy, making it inconvenient for users to carry and limiting the device's flexibility.

[0161] Based on this, by adjusting the structure of the electronic device 100, this application can reduce the weight of the electronic device 100 and improve the stability of the connection between the host 10 and the keyboard 20, thereby providing users with a better user experience. Detailed embodiments are described in conjunction with the accompanying drawings and the following description.

[0162] Please refer to Figures 3, 4, and 5. Figure 3 is a structural diagram of the disassembled main unit 10 and keyboard 20 of the electronic device 100 shown in Figure 2. Figure 4 is a partial structural diagram of the main unit 10 shown in Figure 3. Figure 5 is an exploded view of the main unit 10 shown in Figure 3. In these figures, the X direction represents the width of the main unit 10, the Y direction represents the length of the main unit 10, and the Z direction represents the thickness of the main unit 10.

[0163] The host 10 includes a host body 11, a display module 112, a second hinge assembly 12, and a host bracket 13. The host body 11 includes a display surface 1101 and a non-display surface 1102, which are arranged opposite to each other along the Z-direction. The display module 112 is connected to the display surface 1101 of the host body 11. The host bracket 13 is rotatably connected to the non-display surface 1102 of the host body 11 via the second hinge assembly 12.

[0164] It should be noted that Figure 4 is only intended to schematically illustrate the connection relationship between the main unit 11, the second rotating shaft assembly 12, and the main unit bracket 13, and is not intended to specifically limit the connection positions, specific structures, or quantities of each device. Furthermore, the structure illustrated in the embodiments of this application does not constitute a specific limitation on the main unit 10. In other embodiments of this application, the main unit 10 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements.

[0165] Please refer to Figure 5 again. The main body 11 includes a middle frame 111, a stop assembly 113, and a magnetic component 114. The display module 112, the stop assembly 113, and the magnetic component 114 are all mounted on the middle frame 111. The middle frame 111 is the structure for housing and supporting various components inside the electronic device 100. The display module 112 is located on one side of the middle frame 111 in the thickness direction. The display module 112 can be an LCD (liquid crystal display) or OLED (organic light-emitting diode) display module, used to display images and text, and can also be used to operate the main body 11. The stop assembly 113 can keep the main support 13 at a certain angle relative to the main body 11 when the main support 13 is opened to a certain angle with the main body 11, preventing the main support 13 from moving relative to the main body 11. The magnetic component 114 can be magnetically attracted to the keyboard support of the keyboard 20 and the main support 13.

[0166] Please refer to Figures 6 and 7. Figure 6 is a structural schematic diagram of the middle frame 111 shown in Figure 5 from one angle. The viewing angle of the middle frame 111 shown in Figure 6 is the view from the side of the middle frame 111 facing the display module 112 of the host 10. Figure 7 is a structural schematic diagram of the middle frame 111 shown in Figure 6 from another angle. The viewing angle of the middle frame 111 shown in Figure 7 is the view from the side of the middle frame 111 facing away from the display module 112 of the host 10.

[0167] The middle frame 111 includes a base plate 1111, a side frame 1112, and a support 1113. The side frame 1112 is arranged around the periphery of the base plate 1111. The side frame 1112 and the base plate 1111 surround each other to form a receiving space. The support 1113 is located within the receiving space.

[0168] The base plate 1111 includes a non-display surface 1102 and an inner surface 1115. In the Z direction (the thickness direction of the base plate 1111), the non-display surface 1102 and the inner surface 1115 are arranged opposite to each other. The non-display surface 1102 of the base plate 1111 is also the non-display surface 1102 of the main body 11. The non-display surface 1102 includes a first region 1103 and a second region 1104 connected together, and along the X direction, the first region 1103 and the second region 1104 are arranged sequentially.

[0169] The frame 1112 can be a rectangular frame. The frame 1112 includes a first side 111a and a second side 111b opposite each other along the X direction, and a third side 111c and a fourth side 111d opposite each other along the Y direction. The first side 111a, the fourth side 111d, the second side 111b, and the third side 111c are connected end-to-end in sequence. The first side 111a and the second side 111b are respectively connected to two opposite edges along the X direction of the inner surface 1115 of the base plate 1111. The third side 111c and the fourth side 111d are respectively connected to two opposite edges along the Y direction of the inner surface 1115 of the base plate 1111. The non-display surface 1102 of the base plate 1111 forms the non-display surface 1102 of the main body 11. The surface of the frame 1112 facing the opposite direction to the Z direction is the display surface 1101 of the main body 11.

[0170] The support body 1113 connects the third side 111c and the fourth side 111d, and extends along the Y direction. The support body 1113 is spaced apart from the first side 111a and the second side 111b. The support body 1113 divides the receiving space into two sub-spaces. One sub-space can be used to accommodate the circuit board, camera, battery, and other structures of the host 10. The other sub-space can be used to accommodate the second hinge assembly 12, the stop assembly 113, and the magnetic component 114, and other structures.

[0171] In some embodiments, the support body 1113 and the frame 1112 can jointly support the display module 112, thereby stabilizing the overall structure of the display module 112. The support body 1113 and the frame 1112 can also jointly absorb and disperse external impact forces, thereby protecting the display module 112 from damage. This improves the overall durability and impact resistance of the host 10.

[0172] Please refer to Figure 7 again. The main unit 10 is also provided with a charging port 1116. The charging port 1116 extends through the third side 111c along the Y direction. The charging port 1116 can be located in the middle of the third side 111c.

[0173] Referring again to Figure 6, the middle frame 111 also includes a second pivot through slot 1151, a stop through slot 1152, and a bracket receiving slot 1153. The second pivot through slot 1151 is used for the second pivot assembly 12 to extend and connect with the main unit bracket 13. The stop through slot 1152 is used for the stop assembly 113 to pass through and connect with the main unit bracket 13. The bracket receiving slot 1153 is used to provide accommodating space when the main unit bracket 13 is closed.

[0174] The second pivot groove 1151 extends through the base plate 1111 along the Z direction. The second pivot groove 1151 is located between the support 1113 and the second side 111b. The second pivot groove 1151 can be located on the side opposite to the X direction of the charging hole 1116. For example, the number of second pivot grooves 1151 can be three, and the three second pivot grooves 1151 are spaced apart along the X direction.

[0175] In some possible implementations, referring again to Figure 6, the base plate 1111 may also be provided with a relief groove 1154. The relief groove 1154 is recessed from the inner surface 1115 of the base plate 1111. The relief groove 1154 is located on the side of the second rotating shaft through groove 1151 facing the support body 1113 and communicates with the second rotating shaft through groove 1151. The bottom wall of the relief groove 1154 may be provided with a boss 1155. The boss 1155 may be recessed with a screw hole. The wall of the screw hole can be fixedly connected to the second rotating shaft assembly 12 by a screw.

[0176] The stop groove 1152 extends through the base plate 1111 along the Z direction. The stop groove 1152 is located between the support body 1113 and the second side 111b. For example, there are two stop grooves 1152, which are located in the two gaps between the three second shaft through grooves 1151. The stop grooves 1152 and the second shaft through grooves 1151 are spaced apart.

[0177] Referring again to Figure 7, the bracket receiving groove 1153 is recessed inward from the first region 1103 of the non-display surface 1102 of the base plate 1111. The bracket receiving groove 1153 can extend through the second side 111b, part of the third side 111c, and part of the fourth side 111d. The bracket receiving groove 1153 communicates with the second pivot through groove 1151 and the stop through groove 1152. The width of the bracket receiving groove 1153 in the X direction can be less than half the length of the third side 111c. That is, the width of the bracket receiving groove 1153 in the X direction can be less than half the dimension of the middle frame 111 in the X direction.

[0178] In some possible implementations, the edge of the bracket receiving groove 1153 may also be provided with a clearance groove 1156. The clearance groove 1156 may be recessed from the bottom wall of the bracket receiving groove 1153 and extend through the edge 1112 of the middle frame 111. Exemplarily, there may be two clearance grooves 1156. One clearance groove 1156 may be recessed from the bottom wall of the bracket receiving groove 1153 and extend through the surface of the base plate 1111 facing the opposite direction of the Y direction. The other clearance groove 1156 may be recessed from the bottom wall of the bracket receiving groove 1153 and extend through the surface of the base plate 1111 facing the Y direction.

[0179] In this embodiment, the clearance groove 1156 can provide a force point for the user's hand, so that the user can apply force in different directions to the main body 11 and the main support 13, thereby allowing the main support 13 to open relative to the main body 11.

[0180] Please refer to Figures 8 and 9. Figure 8 is a structural schematic diagram of the closed state of the stop assembly 113 shown in Figure 5. Figure 9 is an exploded schematic diagram of the stop assembly 113 shown in Figure 8. The stop assembly 113 includes a first fixed seat 1131, a second fixed seat 1132, a connecting rod 1133, a slider 1134, a first pin 1135, a second pin 1136, an elastic element 1137, a stop block 1138, and a second magnetic element 1139. The first fixed seat 1131 is used for fixed connection with the main unit bracket 13. The second fixed seat 1132 is used for fixed connection with the middle frame 111 of the main unit body 11. The slider 1134 is slidably connected to the first fixed seat 1131. The connecting rod 1133 is rotatably connected to the slider 1134 via the first pin 1135. The connecting rod 1133 is rotatably connected to the second fixed seat 1132 via the second pin 1136. The stop block 1138 is connected to the first fixed seat 1131. The elastic element 1137 abuts against the stop block 1138 and the first fixed seat 1131. The second magnetic element 1139 is fixedly connected to the stop block 1138.

[0181] Specifically, please refer to Figure 10, which is a structural schematic diagram of the first fixing seat 1131 shown in Figure 9. The first fixing seat 1131 is provided with a sliding groove 1161. The sliding groove 1161 is recessed by a surface of a certain thickness of the first fixing seat 1131. The sliding groove 1161 can extend along the X direction and penetrates two end faces of the first fixing seat 1131 opposite to each other in the X direction. The sidewalls of the sliding groove 1161 can be stepped.

[0182] The first fixed base 1131 is also provided with a stop block through groove 1162, a screw hole 1163 and a positioning hole 1164.

[0183] The bottom wall of the slide 1161 is recessed with a stop block through groove 1162, which penetrates the bottom wall of the slide 1161 and the surface of the first fixed seat 1131 facing the Z direction.

[0184] The screw hole 1163 can penetrate the bottom wall of the slide groove 1161 and the surface of the first fixing seat 1131 facing the Z direction. The screw hole 1163 and the stop block through groove 1162 are arranged sequentially along the extension direction of the slide groove 1161. For example, the number of screw holes 1163 can be three. The three screw holes 1163 can be arranged in a triangle.

[0185] The positioning hole 1164 can penetrate the bottom wall of the slide groove 1161 and the surface of the first fixing seat 1131 facing the Z direction. The positioning hole 1164 can be located on the side of the stop block through groove 1162 opposite to the screw hole 1163. For example, there can be two positioning holes 1164. The two positioning holes 1164 can be spaced apart along the Y direction.

[0186] Referring again to Figure 9, the first fixed base 1131 is also provided with positioning posts 1165. The positioning posts 1165 protrude from the surface of the first fixed base 1131 facing away from the slide groove. For example, there can be two positioning posts 1165, and the two positioning posts 1165 can be arranged at intervals in the Y direction. In the Y direction, the two positioning posts 1165 are respectively located on opposite sides of the stop block through groove 1162.

[0187] The elastic element 1137 can be a spring. For example, there can be two elastic elements 1137. The two elastic elements 1137 can be respectively sleeved on the two positioning posts 1165.

[0188] The slider 1134 is provided with a first pivot hole 1171, a first limiting groove 1172, a first rotation clearance groove 1173 and a connecting rod clearance groove 1174.

[0189] The first pivot hole 1171 passes through the slider 1134 along the Y direction.

[0190] There can be two first limiting grooves 1172. One first limiting groove 1172 is recessed in the surface of the slider 1134 facing the Y direction and penetrates the surface of the slider 1134 facing the opposite Z direction and the two opposing surfaces of the slider 1134 in the X direction. The other first limiting groove 1172 is recessed in the surface of the slider 1134 facing the opposite Y direction and penetrates the surface of the slider 1134 facing the opposite Z direction and the two opposing surfaces of the slider 1134 in the X direction. The two first limiting grooves 1172 communicate with the first rotating shaft hole 1171.

[0191] The first rotation clearance groove 1173 is recessed from the surface of the slider 1134 facing the opposite direction to the X direction. The first rotation clearance groove 1173 penetrates the two opposing surfaces of the slider 1134 in the Z direction. The first pivot hole 1171 penetrates the two sidewalls of the first rotation clearance groove 1173 along the Y direction.

[0192] The connecting rod clearance groove 1174 is recessed from the surface of the slider 1134 in the opposite direction to the Z direction. The connecting rod clearance groove 1174 penetrates two opposing surfaces of the slider 1134 in the X direction.

[0193] The slider 1134 is slidably mounted in the groove 1161 of the first fixed base 1131, and both sides of the slider 1134 are slidably connected to the groove 1161. The groove wall of the first limiting groove 1172 can be opposite to the stepped groove side wall of the groove 1161. The opening of the connecting rod clearance groove 1174 faces the opening of the groove 1161.

[0194] The two ends of the first pin 1135 are rotatably connected to the wall of the first rotating shaft hole 1171. The middle part of the first pin 1135 is located in the first rotating clearance groove 1173.

[0195] The connecting rod 1133 has a first pin through hole 1175 and a second pin through hole 1176 at its two opposite ends in the X direction. Both the first pin through hole 1175 and the second pin through hole 1176 penetrate the connecting rod 1133 in the Y direction. The first pin through hole 1175 is fitted into the middle part of the first pin 1135. The second pin through hole 1176 is fitted into the middle part of the second pin 1136.

[0196] In this embodiment, the connecting rod 1133 can swing relative to the slider 1134 with the first pin 1135 as the axis.

[0197] Please refer to Figure 9. The second fixed base 1132 includes a second rotating shaft hole 1181, a second rotation clearance groove 1182, and a mounting groove 1183.

[0198] The second rotation clearance groove 1182 is recessed from the end face of the second fixed seat 1132 facing the opposite direction of the X direction, and the second rotation clearance groove 1182 penetrates the two opposing surfaces of the second fixed seat 1132 in the Z direction. The second shaft hole 1181 penetrates the two sidewalls of the second rotation clearance groove 1182 along the Y direction.

[0199] The mounting groove 1183 is recessed from the surface of the second fixing seat 1132 facing the Z direction and extends through the end face of the second fixing seat 1132 facing the X direction.

[0200] The second fixing seat 1132 may also be provided with screw holes. The screw holes penetrate the bottom wall of the mounting groove 1183 and the surface of the second fixing seat 1132 facing the opposite direction to the Z direction.

[0201] The second rotating shaft hole 1181 of the second fixed seat 1132 is fitted into the middle part of the second pin 1136. The second fixed seat 1132 is connected to the slider 1134 via a connecting rod 1133. The second fixed seat 1132 can be connected to the bracket by screws. Some screws can be located in the mounting groove 1183. The screws pass through the screw holes and are connected to the main unit bracket 13.

[0202] Please refer to Figure 9. The stop block 1138 includes a stop body 1184 and a connecting seat 1185.

[0203] The stop body 1184 protrudes from the surface of the connecting seat 1185 in the Z-axis direction. The stop body 1184 protrudes from both sides of the connecting seat 1185 in the Y-direction.

[0204] The connector 1185 is provided with mounting holes 1186 and magnetic component receiving holes 1187. The mounting holes 1186 are located on opposite sides of the stop body 1184 in the X direction. The mounting holes 1186 protrude from both sides of the stop body 1184 along the Z direction through the connector 1185. The magnetic component receiving holes 1187 protrude from the connector 1185 along the Z direction and are recessed into the interior of the stop body 1184.

[0205] The connecting seat 1185 has one side of the stop body 1184 facing the first fixed seat 1131. A mounting hole 1186 of the connecting seat 1185 is fitted onto a positioning post 1165 of the first fixed seat 1131, so that the elastic member 1137 can abut against the connecting seat 1185 of the first fixed seat 1131 and the stop block 1138.

[0206] The second magnetic component 1139 can be a magnet, and is installed in the magnetic component receiving hole 1187.

[0207] Please refer to Figure 11 again. Figure 11 is a structural schematic diagram of the middle frame 111 shown in Figure 5, which is equipped with a magnetic component 114. The magnetic component 114 of the main unit 11 can be magnetically attracted to the magnetic component of the main unit bracket 13. So that when the main unit bracket 13 is closed, the main unit bracket 13 can be stably maintained in a closed state by being attracted to the main unit 11 through the magnetic component 114.

[0208] In some possible implementations, the magnetic element 114 of the main body 11 can be of various types. These various magnetic elements 114 can be categorized into a third magnetic element 1141 and a fifth magnetic element 1142. The third magnetic element 1141 and the fifth magnetic element 1142 can be mounted on the middle frame 111. The third magnetic element 1141 and the fifth magnetic element 1142 are spaced apart in the width direction of the main body 11. In this embodiment, the magnetic element 114 can be a small magnetic clasp. Exemplarily, the magnetic elements 114 mentioned in this embodiment can all be fixedly connected to the middle frame 111 by being embedded in it.

[0209] The third magnetic component 1141 can be installed on the inner surface 1115 of the middle frame 111.

[0221] The seventh magnetic element 132 is connected to the first edge region 131a of the first bracket 131. For example, there may be multiple seventh magnetic elements 132. Some of the seventh magnetic elements 132 may be installed in the seventh magnetic element 132 mounting groove 1183 of the stop shaft boss 1312, and some of the seventh magnetic elements 132 may be connected to the two end positions of the first edge region 131a.

[0222] The sixth magnetic element 133 is connected to the second edge region 131b of the first bracket 131. For example, there can be multiple sixth magnetic elements 133. Multiple sixth magnetic elements 133 can be spaced apart along the Y direction within the second edge region 131b.

[0223] Referring to Figures 9, 10, and 12, the stop shaft boss 1312 of the main unit bracket 13 is connected to the first fixing seat 1131 of the stop assembly 113. Specifically, the positioning pin 1314 of the stop shaft boss 1312 can be inserted into the positioning hole 1164 of the first fixing seat 1131 to align the stop shaft boss 1312 with the first fixing seat 1131. The screw hole 1163 of the stop shaft boss 1312 is aligned with the screw hole 1316 of the first fixing seat 1131. Screws can pass through the screw holes 1163 of the stop shaft boss 1312 and 1316 of the first fixing seat 1131, thereby locking the stop shaft boss 1312 and the first fixing seat 1131 together.

[0224] Referring to Figures 6 and 9, the middle frame 111 of the main body 11 is connected to the second fixing seat 1132 of the stop assembly 113. Specifically, the inner surface 1115 of the base plate 1111 of the middle frame 111 may be provided with screw holes, which are aligned with the screw holes in the mounting groove 1183 of the second fixing seat 1132. Screws can pass through the screw holes in the base plate 1111 and the screw holes in the mounting groove 1183 of the second fixing seat 1132, thereby locking the middle frame 111 and the second fixing seat 1132 together.

[0225] Please refer to Figures 13 and 14. Figure 13 is a structural schematic diagram of another state of the stop assembly 113 shown in Figure 8. Figure 14 is a partial internal structural schematic diagram of part AA of the main unit 10 shown in Figure 4. When the main unit bracket 13 is opened relative to the main unit body 11, the second fixed seat 1132 of the stop assembly 113 moves with the main unit bracket 13, and the relative position of the second fixed seat 1132 and the first fixed seat 1131 changes. At this time, the slider 1134 of the stop assembly 113 slides within the slide rail of the first fixed seat 1131. One end of the connecting rod 1133 rotates around the first pin 1135 in the first rotation clearance groove 1173 of the slider 1134. The other end of the connecting rod 1133 rotates around the second pin 1136 in the second rotation clearance groove 1182 of the second fixed seat 1132. The angle between the connecting rod 1133 and the first fixed seat 1131 changes. The second fixed seat 1132 moves out of the slide groove 1161 of the first fixed seat 1131. At this time, the stop block 1138 can compress the elastic element 1137 under the repulsive force of the external magnetic force (the magnetic force provided by the keyboard 20 bracket described below), and cause the stop body 1184 to move into the stop block through groove 1162 of the first fixed seat 1131. At this time, the stop body 1184 can block the slider 1134 from continuing to slide in the slide groove 1161, thereby stopping the relative position of the first fixed seat 1131 and the second fixed seat 1132 from changing, and thus keeping the host bracket 13 and the host body 11 at a certain angle for user convenience.

[0226] Please refer to Figure 15, which is an exploded view of the second rotating shaft assembly 12 shown in Figure 5. The second rotating shaft assembly 12 includes a rotating shaft base 121, a rotating component 122, and an auxiliary rotating component 123. The auxiliary rotating component 123 is connected between the rotating shaft base 121 and the rotating component 122. The rotating shaft base 121 is used for fixed connection to the middle frame 111 of the main body 11. The rotating component 122 is used for fixed connection to the main body bracket 13.

[0227] The rotating shaft base 121 includes a first connecting portion 1211 and a first sliding portion 1212. The first connecting portion 1211 is connected to one end of the first sliding portion 1212. The first connecting portion 1211 is provided with a screw hole 1213. Along the Z direction, the screw hole 1213 passes through the first connecting portion 1211. The first sliding portion 1212 has recessed rotating grooves 1214 on both opposite sides in the Y direction. The rotating grooves 1214 extend along the length direction of the first sliding portion 1212. In this embodiment, the rotating grooves 1214 are arc-shaped grooves.

[0228] The rotating component 122 includes a second connecting portion 1221 and a second sliding portion 1222. The second connecting portion 1221 is connected to one end of the second sliding portion 1222. The second connecting portion 1221 is provided with a screw hole 1163. The screw hole 1163 penetrates the second connecting portion 1221 along its thickness direction. The second sliding portion 1222 is provided with a receiving groove 1223. The receiving groove 1223 penetrates the second connecting portion 1221 along the Z direction and is located away from the surface of the second sliding portion 1222. Two limiting bodies 1224 are provided on the sidewall of the receiving groove 1223. The two limiting bodies 1224 are located inside the receiving groove 1223 and are arranged opposite to each other along the Y direction.

[0229] The auxiliary component 123 includes two third sliding portions 1231 and a connecting rod portion 1232. The two third sliding portions 1231 are connected to opposite ends of the connecting rod portion 1232. Each third sliding portion 1231 includes an inner surface 1233 and an outer surface 1234. The inner surface 1233 is the surface of the two third sliding portions 1231 facing each other. The outer surface 1234 is the surface of the two third sliding portions 1231 facing away from each other. The inner surface 1233 is provided with a sliding body 1235. The sliding body 1235 is arc-shaped. The outer surface 1234 is provided with a slide rail 1191. The slide rail 1191 can be arc-shaped.

[0230] The first sliding portion 1212 of the rotating shaft base 121 is connected to the connecting rod of the auxiliary rotating member 123. The groove wall of the rotation groove 1214 of the first sliding portion 1212 of the rotating shaft base 121 mutually limits the sliding body 1235 of the inner side surface 1233 of the auxiliary rotating member 123. The second sliding portion 1222 of the rotating member 122 is connected to the outer side surface 1234 of the auxiliary rotating member 123. The limiting body 1224 of the second sliding portion 1222 mutually limits the groove wall of the slide 1191 of the outer side surface 1234 of the auxiliary rotating member 123.

[0231] During the rotation of the rotating member 122 relative to the rotating shaft base 121, the auxiliary rotating member 123 can rotate relative to the rotating base around the center line of the connecting rod portion 1232, thereby increasing the angle of rotation of the rotating member 122 relative to the rotating shaft base 121. That is, when the rotating member 122 rotates relative to the rotating shaft base 121, the limiting body 1224 of the rotating member 122 slides along the slide rail 1191 of the auxiliary rotating member 123, and at the same time, the sliding body 1235 of the inner surface 1233 of the auxiliary rotating member 123 also slides along the rotation groove 1214 of the rotating base. Thus, by rotating the auxiliary rotating member 123 around the center line of the connecting rod portion 1232 relative to the rotating shaft base 121, the angle of rotation of the rotating member 122 relative to the rotating shaft base 121 is increased.

[0232] Please refer to Figure 16, which is a partial cross-sectional view of the main unit 10 shown in Figure 4 at point DD. The first connecting portion 1211 of the pivot base 121 is connected to the boss 1155 on the bottom wall of the relief groove 1154 of the middle frame 111. Screws can pass through the screw holes 1213 of the first connecting portion 1211 and the screw holes of the boss 1155, thereby fixing the boss 1155 in the relief groove 1154 to the first connecting portion 1211.

[0233] The second connecting portion 1221 of the rotating member 122 is connected to the second rotating shaft boss 1311 of the main bracket 13. Screws can pass through the screw holes of the second connecting portion 1221 and the screw holes of the second rotating shaft boss 1311, thereby fixing the second rotating shaft boss 1311 to the second connecting portion 1221.

[0234] After the main body 11 and the main bracket 13 are rotatably connected through the second rotating shaft assembly 12, the rotating part 122 of the second rotating shaft assembly 12 can rotate relative to the rotating shaft base 121, so that the main bracket 13 can switch between the closed state and the open state.

[0235] In this embodiment, the second hinge assembly 12 can utilize the fragmented space in the host 10, thereby avoiding increasing the overall size of the host 10 and making the appearance of the host 10 more concise.

[0236] When the main unit 11 and the main unit bracket 13 are closed, the fifth magnetic element 1142 of the main unit 11 and the sixth magnetic element 133 of the main unit bracket 13 are at least partially opposite to each other. At this time, the fifth magnetic element 1142 and the sixth magnetic element 133 attract each other so that the main unit bracket 13 and the main unit 11 can be kept in a closed state, thereby facilitating the user to use the main unit 10 alone.

[0237] The host 10 may also include one or more of the following structures: buttons, a touch layer, and a circuit board. The touch layer allows users to perform touch operations and can be a transparent glass cover, plastic, or other materials with good light transmittance. The buttons can be power buttons or volume buttons, and the number of buttons can be one, two, or three, etc., which is not limited in this application. The circuit board can be located inside the host 10 and can be the motherboard of the host 10.

[0238] In some other possible implementations, the host 10 may also include a battery and a camera, the camera being used to capture pictures or videos to meet the shooting needs of the host 10, and the battery being located inside the host 10 to power the host 10.

A first pen groove 2115 is spaced apart from the first hinge receiving groove 2112. For example, the length of the first pen groove 2115 can be less than the length of the first hinge receiving groove 2112.

[0246] Please refer to Figures 18 and 19. The keyboard housing 211 and the base housing 212 are stacked in the Z direction. The first pivot receiving groove 2112 of the keyboard housing 211 communicates with the pivot cover clearance groove 2121 of the base housing 212. The key assembly 213 is located between the keyboard housing 211 and the base housing 212. The key assembly 213 protrudes from the keyboard 20 through hole of the keyboard housing 211. The touchpad 214 can be installed on the side of the keyboard housing 211 away from the base housing 212. The touchpad 214 is located on the side of the key assembly 213 away from the pivot area 21b. The feet 215 are located on the side of the base housing 212 away from the keyboard housing 211. For example, there can be four feet 215.

[0247] In this embodiment, the button group 213 of the electronic device 100 provides users with efficient and convenient input and control means through its rich button combinations and functional design, enabling users to easily interact and communicate with the electronic device 100.

[0248] The touchpad 214 is an input device widely used in laptops. It controls cursor movement by sensing the movement of the user's fingers and can serve as a replacement for the mouse, providing users with a more convenient and efficient interactive experience.

[0249] The design of the foot 215 creates a space between the bottom of the electronic device 100 and the desktop, which facilitates air circulation and improves the heat dissipation of the electronic device 100. The foot 215 also increases the friction between the electronic device 100 and the supporting surface, thus preventing the electronic device 100 from sliding or tipping over during use.

[0250] Please refer to Figure 20, which is an exploded view of the keyboard bracket 22 shown in Figure 17. The keyboard bracket 22 includes a second bracket 221, a fourth magnetic element 222, a first magnetic element 223, an eighth magnetic element 224, a bracket cover 225, a hinge cover 226, and a pen holder 227. The second bracket 221 provides mounting positions for the fourth magnetic element 222, the first magnetic element 223, the eighth magnetic element 224, the bracket cover 225, the hinge cover 226, and the pen holder 227.

[0251] Please refer to Figure 21, which is a structural schematic diagram of the keyboard bracket 22 equipped with a fourth magnetic element 222, a first magnetic element 223, and an eighth magnetic element 224.

The reinforcing rib 2217 is spaced apart from the fourth magnetic element 222, the first magnetic element 223, and the eighth magnetic element 224 described above.

[0262] In this embodiment, the reinforcing rib 2217 can effectively disperse and resist the force exerted by the host 10 on the keyboard support 22, thereby enhancing the overall strength and rigidity of the keyboard support 22 structure. The reinforcing rib 2217 uses less material while maintaining the structural strength of the keyboard support 22. This not only reduces costs but also lightens the overall weight of the keyboard support 22.

[0263] Please refer to Figure 22, which is a structural schematic diagram of the pivot cover 226 shown in Figure 20. The pivot cover 226 includes a pivot cover body 2260, an extension plate 2261, and a limiting body 2262. The extension plate 2261 is connected to the side of the pivot cover body 2260 facing the thickness direction and extends away from the pivot cover body 2260. The extension plate 2261 is provided with screw holes 1163. The screw holes 1163 penetrate the extension plate 2261 along the thickness direction. For example, there can be two extension plates 2261. The two extension plates 2261 are spaced apart along the length direction of the pivot cover body 2260. The extension plates 2261 are used for fixed connection with the second bracket 221.

[0264] The limiting body 2262 is disposed on one side of the shaft cover body 2260 in the thickness direction, and is disposed on the same side as the extension plate 2261. The limiting body 2262 extends along the length direction of the shaft cover body 2260. The limiting body 2262 is located on the side of the extension plate 2261 facing the opposite direction of the Z direction. The limiting body 2262 and the extension plate 2261 are spaced apart.

[0265] The limiting body 2262 is provided with a shaft clearance groove 2263. The shaft clearance groove 2263 extends through the limiting body 2262 along the Z-axis direction. For example, the number of shaft clearance grooves 2263 can be four. The four shaft clearance grooves 2263 are spaced apart along the Y-axis direction.

[0266] The hinge cover 226 is located within the first hinge receiving groove 2112 of the keyboard housing 211 and the second hinge receiving groove 2210 of the keyboard bracket 22. An extension plate 2261 of the hinge cover 226 is connected to the keyboard connecting portion 2211 of the second bracket 221. The extension plate 2261 can be connected between two adjacent second recesses 2214 of the keyboard connecting portion 2211. The extension plate 2261 can be fixedly connected to the keyboard connecting portion 2211 by screws.

[0267] When the keyboard 20 is closed, the non-display surface 1102 of the hinge cover body 2260 can be flush with the surface of the keyboard support 22 facing the opposite direction of the X direction and the surface of the keyboard body 21 facing the opposite direction of the X direction.

[0268] Please refer to Figures 23, 24, and 25. Figure 23 is a structural schematic diagram of the keyboard 20 shown in Figure 1 in the closed state. Figure 24 is a cross-sectional schematic diagram of the keyboard 20 shown in Figure 23 at point BB. Figure 25 is a side view of the keyboard 20 shown in Figure 23. When the keyboard support 22 is in the closed state, the side of the keyboard 20 facing the opposite direction to the X direction can be divided into three appearance structures. Along the Y direction, the first appearance surface includes the surface of the second support 221 of the keyboard support 22 facing the opposite direction to the X direction, and the surface of the keyboard shell 211 of the keyboard body 21 facing the opposite direction to the X direction. The second appearance surface is the surface of the hinge cover 226 facing away from the extension plate 2261. The third appearance structure includes the surface of the second support 221 of the keyboard support 22 facing the opposite direction to the X direction, and the surface of the keyboard shell 211 of the keyboard body 21 facing the opposite direction to the X direction.

[0269] Since the width (X-direction dimension) of the keyboard bracket 22 is smaller than the width (X-direction dimension) of the keyboard body 21, when the keyboard bracket 22 is in the closed state, the keyboard bracket 22 and the keyboard body 21 are stacked, and the touchpad 214 and at least part of the key group 213 are exposed relative to the keyboard bracket 22.

[0270] For example, in some other possible embodiments, with the keyboard bracket 22 stacked on top of the keyboard body 21, the keyboard bracket 22 may also cover the entire key group 213. The touchpad 214 is exposed relative to the keyboard bracket 22.

[0271] Alternatively, when the keyboard stand 22 is stacked with the keyboard body 21, the keyboard stand 22 can also cover all the key groups 213 and part of the touchpad 214. Additionally, part of the touchpad 214 is exposed relative to the keyboard stand 22.

[0272] In this embodiment, the keyboard of a typical electronic device needs to be frequently carried or moved for use. The keyboard stand 22 of this application is smaller in size; the smaller size of the keyboard stand 22 means that the entire keyboard 20 is more compact and lightweight, making it easier for users to carry. The reduced size of the keyboard stand 22 helps to reduce the overall weight of the keyboard 20. The lighter weight reduces the burden on the user during use and improves comfort during extended use.

[0273] A smaller keyboard stand takes up less space when stored or carried. For example, the compact keyboard design makes it easier to fit into a backpack or handbag when traveling or commuting.

[0274] Please refer to Figure 26, which is a structural schematic diagram of the pen holder 227 shown in Figure 20. The pen holder 227 includes a first section 2271 and a second section 2272. The first section 2271 and the second section 2272 are bent and connected. The second section 2272 is provided with a second pen slot 2273 and a housing clearance slot 2274. The second pen slot 2273 is recessed from the surface of the second section 2272 away from the first section 2271. The second pen slot 2273 extends along the Y direction and is located at the middle position of the second section 2272 in the Y direction.

[0275] There are two housing clearance slots 2274. The two housing clearance slots 2274 are located at both ends of the second segment 2272 along the Y direction. The housing clearance slots 2274 are recessed from the surface of the second segment 2272 away from the first segment 2271. The two housing clearance slots 2274 are located at opposite ends of the second pen groove 2273 along the Y direction, and the housing clearance slots 2274 and the second pen groove 2273 are spaced apart.

[0276] Referring to Figures 21 and 26, the pen holder 227 is mounted on the keyboard connector 2211. The first segment 2271 of the pen holder 227 covers the surface of the keyboard connector 2211 facing the host connector 2212. The second segment 2272 of the pen holder 227 covers the first recess 2213 and the second recess 2214. The groove of the partial housing clearance groove 2274 can be located within the first recess 2213.

[0277] The bracket cover 225 is connected to the main unit connection part 2212. The bracket cover 225 covers the fourth magnetic element 222, the first magnetic element 223, the eighth magnetic element 224 and the reinforcing rib 2217.

[0278] Please refer to Figure 27, which is an exploded view of the first rotating shaft assembly 23 shown in Figure 16. The first rotating shaft assembly 23 includes multiple torque units 231. Each torque unit 231 includes a spindle 2311, a first fixing member 2312, a second fixing member 2313, a cam 2314, a friction plate 2315, and a fastener 2316. The first fixing member 2312, the second fixing member 2313, the cam 2314, the friction plate 2315, and the fastener 2316 are all sleeved on the spindle 2311.

[0279] Please refer to Figure 28, which is a structural schematic diagram of the mandrel 2311 shown in Figure 27. The mandrel 2311 includes a first connecting segment 2321, a second connecting segment 2322, and a third connecting segment 2323. Along the axial direction of the mandrel 2311, the first connecting segment 2321, the second connecting segment 2322, and the third connecting segment 2323 are connected sequentially. The first connecting segment 2321 is provided with a first engaging surface 2324. The first engaging surface 2324 is recessed relative to the circumferential surface of the first connecting segment 2321 and extends along the axial direction of the mandrel 2311. For example, there can be two first engaging surfaces 2324. The two first engaging surfaces 2324 can be arranged opposite each other radially along the first connecting segment 2321.

[0280] The second connecting segment 2322 is provided with a limiting baffle 2325 and a limiting protrusion 2326. The limiting baffle 2325 is connected to the connection between the second connecting segment 2322 and the first connecting segment 2321. The limiting baffle 2325 is arranged around the periphery of the second connecting segment 2322. The limiting protrusion 2326 is connected to the side of the limiting baffle 2325 opposite to the first connecting segment 2321.

[0281] The third connecting section 2323 is provided with a second engaging surface 2327. The second engaging surface 2327 is partially recessed relative to the circumferential surface of the third connecting section 2323, and extends axially along the mandrel 2311. Exemplarily, there are two second engaging surfaces 2327. The two second engaging surfaces 2327 may be arranged radially opposite to each other along the third connecting section 2323. The end of the third connecting section 2323 away from the second connecting section 2322 may also be threaded.

[0282] Please refer to Figure 27 again. The first fixing member 2312 is provided with a first mandrel through hole 2331 and a first fixing through hole 2332. The first mandrel through hole 2331 penetrates the first fixing member 2312 along the Y direction. The first fixing through hole 2332 penetrates the first fixing member 2312 along the Z direction. The first mandrel through hole 2331 and the first fixing through hole 2332 are spaced apart along the X direction.

[0283] The first mandrel through hole 2331 of the first fixing member 2312 is sleeved on the first connecting section 2321. The shape of the hole wall of the first mandrel through hole 2331 is adapted to the outer peripheral surface of the first connecting section 2321. The hole wall of the first mandrel through hole 2331 and the groove wall of the first snap-fit ​​surface 2324 of the first connecting section 2321 mutually limit each other, so that the rotation of the first fixing member 2312 can drive the mandrel 2311 to rotate.

[0284] Please refer to Figures 29 and 30. Figure 29 is a structural schematic diagram of the second fixing member 2313 shown in Figure 27 from one angle. Figure 30 is a structural schematic diagram of the second fixing member 2313 shown in Figure 27 from another angle. The second fixing member 2313 includes a spindle connecting part 2333 and a keyboard fixing part 2334. The spindle connecting part 2333 is connected to one end of the keyboard fixing part 2334.

[0285] The spindle connecting portion 2333 is provided with a second spindle through hole 2335. The second spindle through hole 2335 extends through the spindle connecting portion 2333 along the Y direction. The spindle connecting portion 2333 is provided with a positioning structure 2336. The positioning structure 2336 is connected to the axial end of the spindle connecting portion 2333 and is located at the edge of the second spindle through hole 2335. The positioning structure 2336 protrudes relative to the end face of the spindle connecting portion 2333. The axial direction of the spindle connecting portion 2333 is the Y direction.

[0286] The mandrel connecting portion 2333 has a first recess 2337 and a second recess 2338 on its end face away from the positioning structure 2336. Both the first recess 2337 and the second recess 2338 are recessed from the end face of the mandrel connecting portion 2333 away from the positioning structure 2336. The first recess 2337 and the second recess 2338 are located on opposite sides of the second mandrel through hole 2335 and are spaced apart.

[0287] The first recess 2337 includes a first sidewall 2341, a second sidewall 2342, and a first bottom wall 2343. The first sidewall 2341 and the second sidewall 2342 are connected to opposite sides of the first bottom wall 2343. The first bottom wall 2343 can be parallel to the end face of the spindle connecting part 2333. The side of the first sidewall 2341 facing away from the first bottom wall 2343 is connected to the end face of the spindle connecting part 2333. The side of the second sidewall 2342 facing away from the first bottom wall 2343 is connected to the end face of the spindle connecting part 2333. The first sidewall 2341, the first bottom wall 2343, and the second sidewall 2342 are arranged sequentially along the periphery of the second spindle through hole 2335. The angle between the first sidewall 2341 and the first bottom wall 2343 is greater than the angle between the second sidewall 2342 and the first bottom wall 2343. The angle between the first sidewall 2341 and the first bottom wall 2343 can be understood as the angle between two planes. It can be understood that the angle between the two planes is less than 90°.

[0288] The second recess 2338 includes a third sidewall 3444, a fourth sidewall 3445, and a second bottom wall 3446. The third sidewall 3444 and the fourth sidewall 3445 are connected to opposite sides of the second bottom wall 3446. The second bottom wall 3446 can be parallel to the end face of the spindle connecting portion 2333. The side of the third sidewall 3444 facing away from the second bottom wall 3446 is connected to the end face of the spindle connecting portion 2333. The side of the fourth sidewall 3445 facing away from the second bottom wall 3446 is connected to the end face of the spindle connecting portion 2333. The third sidewall 3444, the second bottom wall 3446, and the fourth sidewall 3445 are arranged sequentially along the periphery of the second spindle through hole 2335. The angle between the third sidewall 3444 and the second bottom wall 3446 is greater than the angle between the fourth sidewall 3445 and the second bottom wall 3446. The angle between the third side wall 3444 and the second bottom wall 3446 can be understood as the angle between two planes. It is understood that the angle between the two planes is less than 90°.

[0289] Along the circumference of the second mandrel through hole 2335, the first side wall 2341, the first bottom wall 2343, the second side wall 2342, the part end face of the mandrel connecting part 2333, the third side wall 3444, the second bottom wall 3446, and the fourth side wall 3445 of the first recess 2337 are arranged in sequence.

[0290] In some possible implementations, there may be two first recesses 2337, which are arranged radially opposite to each other along the axial connection. There may also be two second recesses 2338, which are arranged radially opposite to each other along the axial connection.

[0291] With the keyboard bracket 22 in the closed state, one end of the keyboard fixing part 2334 is connected to the peripheral side of the spindle connecting part 2333 and extends in the X direction. The keyboard fixing part 2334 is provided with a second fixing through hole 2347. The second fixing through hole 2347 penetrates the keyboard fixing part 2334 along the Z direction.

[0292] Referring again to Figures 27-30, the second mandrel through hole 2335 of the second fixing member 2313 is sleeved on the second connecting section 2322 of the mandrel 2311. The positioning structure 2336 of the second fixing member 2313 and the limiting protrusion 2326 can mutually limit each other. The first recess 2337 and the second recess 2338 of the second fixing member 2313 face the third connecting section 2323 of the mandrel 2311.

[0293] Please refer to Figure 31, which is a structural schematic diagram of the cam 2314 shown in Figure 27. The cam 2314 has a third spindle through-hole 2351. The third spindle through-hole 2351 extends through the cam 2314 along its axial direction. The axial direction of the cam 2314 is the Y direction. The cam 2314 has a first protrusion 2352 and a second protrusion 2353. The first protrusion 2352 and the second protrusion 2353 are respectively located on two opposite end faces of the cam 2314 along its axial direction.

[0294] There can be two first protrusions 2352. The two first protrusions 2352 are opposite each other in the radial direction of the cam 2314. Each first protrusion 2352 includes a first abutment surface 2354, a second abutment surface 2355, and a connecting surface 2356. The first abutment surface 2354 and the second abutment surface 2355 are respectively connected to opposite sides of the connecting surface 2356. Along the circumference of the cam 2314, the first abutment surface 2354, the connecting surface 2356, and the second abutment surface 2355 are connected sequentially. The angle between the first abutment surface 2354 and the connecting surface 2356 is greater than the angle between the second abutment surface 2355 and the connecting surface 2356. The angles between the first abutment surface 2354 and the connecting surface 2356, and the angles between the second abutment surface 2355 and the connecting surface 2356, can be understood as the angles between two planes. It is understood that the angle between the two planes is less than 90°.

[0295] The second protrusion 2353 is connected to the end face of the cam 2314 opposite to the first protrusion 2352. The second protrusion 2353 extends away from the cam 2314. For example, there may be two second protrusions 2353. The two second protrusions 2353 are arranged opposite each other along the radial direction of the cam 2314.

[0296] The third spindle through-hole 2351 of the cam 2314 is fitted onto the third connecting section 2323 of the spindle 2311. The shape of the hole wall of the third spindle through-hole 2351 is adapted to the shape of the outer peripheral surface of the third connecting section 2323. The hole wall of the third spindle through-hole 2351 and the groove wall of the second engaging surface 2327 of the third connecting section 2323 mutually limit each other, so that the rotation of the spindle 2311 can drive the cam 2314 to rotate. The first protrusion 2352 of the cam 2314 can mutually limit each other with the groove wall of the first recess 2337 or the groove wall of the second recess 2338 of the second fixing member 2313.

[0297] Referring again to Figure 27, in some possible embodiments, the torque unit 231 may also be provided with a fastening plate 2317. The fastening plate 2317 is provided with a second protrusion receiving groove 2318. The second protrusion receiving groove 2318 extends through the fastening plate 2317 along its thickness direction. The thickness direction of the fastening plate 2317 is the Y direction. For example, there may be two second protrusion receiving grooves 2318, and the two second protrusion receiving grooves 2318 may be radially opposite each other along the fastening plate 2317.

[0298] The fastening plate 2317 is sleeved on the third connecting section 2323 of the spindle 2311. The fastening plate 2317 is located on the side of the cam 2314 opposite to the second fixing member 2313. The groove wall of the second protrusion receiving groove 2318 of the fastening plate 2317 and the second protrusion 2353 mutually limit each other.

[0299] Friction plate 2315 is sleeved on the third connecting section 2323 of spindle 2311. Friction plate 2315 is located on the side of fastening plate 2317 opposite to cam 2314. There can be multiple friction plates 2315. Multiple friction plates 2315 can provide axial pressure to cam 2314 so that cam 2314 can abut against second fixing member 2313.

[0300] Fastener 2316 is sleeved on the third connecting section 2323 of the spindle 2311, and fastener 2316 can connect with the threaded portion of the third connecting section 2323. Fastener 2316 is located on the side of friction plate 2315 opposite to fastening plate 2317. Fastener 2316 can fix cam 2314, fastening plate 2317, friction plate 2315, etc. on spindle 2311, preventing cam 2314, fastening plate 2317, and friction plate 2315 from falling off spindle 2311.

[0301] In some possible implementations, a shim 2319 may also be provided between the fastener 2316 and the friction plate 2315. The shim 2319 can disperse the pressure between the friction plate 2315 and the screw, making the pressure distribution between the friction plate 2315 and the screw more uniform, thereby preventing the friction plate 2315 from being deformed due to concentrated force and losing its elasticity.

[0302] The first rotating shaft assembly 23 may include two torque units 231. The two torque units 231 of the first rotating shaft assembly 23 may be mirror-symmetrical. The third connecting sections 2323 of the two spindles 2311 are opposite to each other, and the first connecting sections 2321 of the two spindles 2311 are opposite to each other.

[0303] The first rotating shaft assembly 23 may also be provided with a connecting sleeve 236 and a blocking tube 237. The connecting sleeve 236 is connected to the third connecting section 2323 of the two spindles 2311. The blocking tube 237 may be sleeved on the outer periphery of the cam 2314, fastening plate 2317, friction plate 2315, fastener 2316 and connecting sleeve 236 of the two torque units 231.

[0304] In this embodiment, the connecting sleeve 236 can fix the two spindles 2311 of the first rotating shaft assembly 23 together, so that the two spindles 2311 can rotate coaxially and have the same rotation angle. This ensures that the opening angle of the keyboard bracket 22 is the same at different positions, improving the reliability of opening the keyboard bracket 22. The shielding tube 237 can shield the cam 2314, fastening plate 2317, friction plate 2315, fastener 2316, and connecting sleeve 236 of the torque unit 231, making the appearance of the first rotating shaft assembly 23 simpler. This prevents the cam 2314, fastening plate 2317, friction plate 2315, and fastener 2316 of the torque unit 231 from being directly impacted by external forces and deformed, thus affecting the rotation process of the torque unit 231.

[0305] For example, referring again to Figures 17 and 27, the number of first hinge assemblies 23 can be two. The two first hinge assemblies 23 can be arranged alternately along the Y direction. A first fixing member 2312 is connected to the keyboard housing 211. The first fixing through hole 2332 of the first fixing member 2312 corresponds to the screw hole 1163 in the hinge fixing groove 2113 of the keyboard housing 211. One first fixing member 2312 is fixedly connected to the groove wall of one hinge fixing groove 2113 of the keyboard housing 211 by screws. Part of the first fixing member 2312 can be located within a shaft clearance groove 2263 of the hinge cover 226.

[0306] In this embodiment, the hinge between the keyboard bracket 22 and the keyboard body 21 transforms a single torque range into multiple smaller torque ranges. That is, the keyboard bracket 22 and the keyboard body 21 are connected via multiple torque units 231 or multiple first hinge assemblies 23. This disperses the torque between the keyboard bracket 22 and the keyboard body 21 into multiple smaller torques. This reduces the torque borne by each individual torque unit 231, allowing for a smaller size of the torque unit 231. This reduces the installation space occupied by the torque unit 231 on the keyboard 20, resulting in a simpler overall appearance and contributing to the miniaturization of the keyboard 20.

[0307] The second fixing member 2313 is connected to the keyboard bracket 22. The second fixing through hole 2347 of the second fixing member 2313 corresponds to the screw hole 1163 in a second groove 2214 of the keyboard bracket 22. One second fixing member 2313 is fixedly connected to the groove wall of a second groove 2214 of the keyboard bracket 22 through the screw hole 1163. Part of the second fixing member 2313 may be located in another shaft clearance groove 2263 of the hinge cover 226.

[0308] When the keyboard bracket 22 is in the closed state, please refer to Figure 32, which is a schematic diagram of the contact surface structure between the second fixing member 2313 and the cam 2314 shown in Figure 27. Both the cam 2314 and the second fixing member 2313 are in their initial states. The two first protrusions 2352 of the cam 2314 are respectively located within the two first recesses 2337 of the second fixing member 2313. The first abutting surface 2354 of the first protrusion 2352 abuts against the first sidewall 2341 of the first recess 2337. The connecting surface 2356 of the first protrusion 2352 abuts against the first bottom wall 2343 of the first recess 2337. The second abutting surface 2355 of the first protrusion 2352 abuts against the second sidewall 2342 of the first recess 2337.

[0309] Please refer to Figures 32 and 33. Figure 33 is a line graph showing the torque change during the rotation of the second fixing member 2313 and the cam 2314 shown in Figure 32. During the opening of the keyboard bracket 22, the keyboard body 21 remains stationary, therefore the first fixing member 2312 remains stationary, thus keeping the spindle 2311 and the structural member fitted on the third connecting section 2323 of the spindle 2311 stationary. The keyboard bracket 22 drives the second fixing member 2313 to rotate, causing the first protrusion 2352 to gradually slide out of the first recess 2337. The second abutment surface 2355 of the first protrusion 2352 slides along the extending direction of the second sidewall 2342. The friction plate 2315 can be compressed, and the first protrusion 2352 moves away from the second fixing member 2313.

[0310] At this time, since the angle between the second sidewall 2342 and the first bottom wall 2343 is small (smaller than the angle between the first sidewall 2341 and the first bottom wall 2343), the torque M1 that the first protrusion 2352 needs to overcome to slide out of the first recess 2337 is small.

[0311] When the first protrusion 2352 has slid out of the first recess 2337, the first bottom wall 2343 abuts against the end face of the spindle connecting portion 2333. The first bottom wall 2343 slides on the end face of the spindle connecting portion 2333. At this time, the first protrusion 2352 does not displace in the Y direction. There is friction between the first bottom wall 2343 of the first protrusion 2352 and the end face of the spindle connecting portion 2333. At this time, the cam 2314 can rotate relative to the initial state by a first preset angle α1. The first preset angle α1 is less than 70°. For example, the range of the first preset angle α1 can be between 40° and 60°. For example, the first preset angle α1 can be 50°.

[0312] When the first protrusion 2352 slides to the area where the second recess 2338 is located, the first abutment surface 2354 of the first protrusion 2352 slides along the third sidewall 3444 of the second fixing member 2313. At this time, the first protrusion 2352 can move closer to the second fixing member 2313 under the elastic force of the friction plate 2315, so that the first protrusion 2352 is embedded in the second recess 2338, and the keyboard bracket 22 is in the open state. At this time, the first abutment surface 2354 of the first protrusion 2352 can abut against the third sidewall 3444 of the second recess 2338. The connecting part of the first protrusion 2352 can abut against the second bottom wall 3446 of the second recess 2338. The second abutment surface 2355 of the first protrusion 2352 abuts against the fourth sidewall 3445 of the second recess 2338. During the process of the first protrusion 2352 sliding into the second recess 2338, the torque between the first protrusion 2352 and the second fixing member 2313 is less than M1. The first protrusion 2352 can automatically slide into the second recess 2338 under the elastic force of the friction plate 2315, so that the keyboard bracket 22 can automatically open to the second preset angle α2. The second preset angle α2 is greater than or equal to 70°. For example, the second preset angle α2 can be 75°. At this time, the positioning structure 2336 of the second fixing member 2313 abuts against the limiting protrusion 2326 of the spindle 2311, so that the included angle between the second fixing bracket and the first fixing member 2312 is maintained at the second preset angle α2. When the electronic device 100 is in the unfolded state, the second preset angle α2 can be the predetermined angle at which the keyboard bracket 22 is opened. That is, the angle that the user is accustomed to in the use state.

[0313] In this embodiment, when the first protrusion 2352 automatically slides into the second recess 2338, the keyboard bracket 22 automatically opens. Users do not need to manually adjust the opening angle of the keyboard bracket 22 to quickly reach a suitable usage state, greatly improving ease of use. Automatically opening to the second preset angle α2 ensures that the keyboard bracket 22 is at the optimal angle during use, reducing improper angles of the host 10 caused by improper keyboard bracket 22 angles, and avoiding visual fatigue or discomfort in hand operation caused by host 10 angle issues.

[0314] When the keyboard bracket 22 changes from the open state to the closed state, during the process of rotating from the second preset angle α2 to the first preset angle α1, the first protrusion 2352 can slide out from the second recess 2338. At this time, the first abutting surface 2354 of the first protrusion 2352 slides along the third sidewall 3444 of the second recess 2338. Since the angle between the third sidewall 3444 and the second bottom wall 3446 is relatively large (greater than the angle between the fourth sidewall 3445 and the second bottom wall 3446), the torque M1' required for the first protrusion 2352 to slide out from the second recess 2338 is greater than M1.

[0315] When the cam 2314 rotates to the point where the first protrusion 2352 slides out of the second recess 2338, the torque of the first fixing member 2312 relative to the cam 2314 enters a smooth phase. The torque of the first fixing member 2312 relative to the cam 2314 is M1.

[0316] When the cam 2314 rotates to the area where the first recess 2337 is located, the second abutment surface 2355 of the first protrusion 2352 slides along the second sidewall 2342 of the first recess 2337. Under the elastic force of the friction plate 2315 and the action of external force, the first protrusion 2352 can move towards the second fixing member 2313, so that the first protrusion 2352 slides into the first recess 2337. During the process of the first protrusion 2352 sliding into the first recess 2337, the keyboard bracket 22 can be automatically closed, so that the closing action felt by the user when closing the keyboard bracket 22 can be smooth and stable, thereby improving the user's operating convenience.

[0317] Please refer to Figure 34, which is an enlarged view of point A of the electronic device 100 shown in Figure 2. When the keyboard bracket 22 is in the open state, the keyboard connection portion 2211 of the second bracket 221 protrudes from the end face opposite to the host connection portion 2212, relative to the surface of the base housing 212 of the keyboard body 21 facing the bearing surface. At least a portion of the end face of the keyboard connection portion 2211 facing the opposite direction of the X direction can abut against the bearing surface (the surface on which the electronic device 100 is placed).

[0318] In this embodiment, the host device 10 of the electronic device 100 formed by assembling the tablet and keyboard 20 generally has a relatively large mass, and its center of gravity is relatively high compared to a typical laptop computer. Users may experience instability when typing or using the touchpad. Alternatively, placing the electronic device 100 on an uneven surface may also lead to instability.

[0319] In this embodiment of the electronic device 100, when the keyboard stand 22 is in the open state, the keyboard connection portion 2211 of the second bracket 221 of the keyboard stand 22 can directly abut against the surface on which it is placed. The surface at the placement point can directly provide support to the second bracket 221, thereby making the host 10 connected to the keyboard stand 22 less prone to shaking, reducing the impact of the host 10's shaking on the keyboard body 21, and preventing the center of gravity of the electronic device 100 from shifting away from the keyboard body 21 when the user touches the host 10, thus avoiding the electronic device 100 tipping over. This improves the stability of the electronic device 100.

[0320] The host stand 13 of the host 10 can be connected to the keyboard stand 22 of the keyboard 20. The surface of the host stand 13 facing away from the host body 11 faces the stand cover 225 of the keyboard stand 22. The keyboard stand 22 can cover the entire surface of the host stand 13 facing away from the host body 11, or the keyboard stand 22 can cover a portion of the surface of the host stand 13 facing away from the host body 11.

[0321] For example, please refer to Figure 35, which is a schematic diagram of the electrical connection path between the host 10 and the keyboard 20 shown in Figure 3. The host bracket 13 is provided with a first electrical connection point 1301, a circuit board 1302, a battery 1303, and a flexible circuit board 1304. The first electrical connection point 1301 is exposed relative to the surface of the host bracket 13 that is away from the host body 11.

[0322] Circuit board 1302 is electrically connected to the first electrical connection point 1301 via flexible circuit board 1304. Circuit board 1302 is also electrically connected to battery 1303 via flexible circuit board 1304. Circuit board 1302 can be the motherboard of host 10. For example, the motherboard is the connection center for all internal components of host 10. It connects key hardware such as processor, memory, storage devices, graphics card (if integrated on the motherboard), and power management module through various slots, interfaces, and cables to form a complete system.

[0323] The keyboard 20 has a second electrical connection point 2201, a circuit board 2202, and a flexible circuit board 2203. The second electrical connection point 2201 is exposed relative to the bracket cover 225 of the keyboard bracket 22. The circuit board 2202 can be installed inside the keyboard body 21.

[0324] For example, the charging port 2215 of the keyboard 20 can be located on the side of the keyboard connection portion 2211 of the keyboard stand 22. Alternatively, the charging port 2215 of the keyboard 20 can be located on the side of the keyboard body 21.

[0325] In this embodiment, the charging port 2215 is located on the side of the keyboard connection part 2211, or the charging port 2215 is located on the side of the keyboard body 21. This allows the position of the charging port 2215 of the electronic device 100 to be similar to the charging position of existing laptops. This design allows users of the electronic device 100 provided in this application to adapt more quickly and reduce operational inconvenience caused by different charging positions.

[0326] The charging port 2215 is electrically connected to the circuit board 2202 and the second electrical connection point 2201 via the flexible circuit board 2203. For example, the circuit board 2202 can be responsible for signal transmission between the keyboard 20 and the host 10 after the keyboard 20 is connected to the host 10. The second electrical connection point 2201 is electrically connected to the charging port 2215.

[0327] When the host bracket 13 is connected to the keyboard bracket 22, the first electrical connection point 1301 and the second electrical connection point 2201 come into contact, so that the keyboard 20 is electrically connected to the host 10. The power supply connected to the charging port 2215 can supply power to the keyboard 20 and the host 10. Furthermore, the circuit board 2202 can communicate with the host 10 through the contact between the second electrical connection point 2201 and the first electrical connection point 1301, so that characters and shortcut key commands entered by the user through the keyboard 20 will be transmitted to the circuit board 1302 of the host 10 by the communication module.

[0328] When the electronic device 100 is in the closed state, the host bracket 13 is stacked on the first region 1103 of the host body 11. The keyboard bracket 22, host bracket 13, host body 11, and keyboard body 21 are stacked in sequence. The second region 1104 of the host body 11 is exposed relative to the keyboard bracket 22.

[0329] Please refer to Figure 36, which is a schematic diagram of the distribution of magnetic components in the electronic device 100 shown in Figure 1. The magnetic components within the range of label 1 are the magnetic components of the keyboard bracket 22. The magnetic components within the range of label 2 are the magnetic components of the host bracket 13. The magnetic components within the range of label 3 are the magnetic components of the host body 11.

[0330] The fourth magnetic element 222 of the keyboard bracket 22 is magnetically attracted to the third magnetic element 1141 of the host body 11. The first magnetic element 223 of the keyboard bracket 22 is magnetically attracted to the seventh magnetic element 132 of the host bracket 13. The eighth magnetic element 224 of the keyboard bracket 22, the sixth magnetic element 133 of the host bracket 13, and the fifth magnetic element 1142 of the host body 11 are arranged sequentially in the Z direction. A portion of the eighth magnetic elements 224 are magnetically attracted to a portion of the sixth magnetic elements 133. Another portion of the eighth magnetic elements 224 can be magnetically attracted to a portion of the fifth magnetic elements 1142. Another portion of the sixth magnetic elements 133 are magnetically attracted to another portion of the fifth magnetic elements 1142.

[0331] It should be noted that, in this embodiment, in addition to the one-to-one magnetic attraction between the fifth magnetic element 1142, the sixth magnetic element 133, and the eighth magnetic element 224, all the eighth magnetic elements 224 of the keyboard bracket 22 can be magnetically attracted to all the sixth magnetic elements 133 of the host bracket 13. All the sixth magnetic elements 133 of the host bracket 13 can be magnetically attracted to all the fifth magnetic elements 1142 of the host body 11. That is, the eighth magnetic elements 224, the sixth magnetic elements 133, and the fifth magnetic elements 1142 can be three layers of magnets, with adjacent layers attracting each other, thereby connecting the keyboard bracket 22, the host bracket 13, and the host body 11 magnetically.

[0332] When the electronic device 100 is in the closed state, the first pen slot 2115 on the keyboard body 21 and the second pen slot 2273 on the keyboard bracket 22 can form a space for accommodating the stylus. The stylus can be located within the space formed by the first pen slot 2115 and the second pen slot 2273.

[0333] In this embodiment, the host 10 is located in the X-direction of the pen holder 227 of the keyboard bracket 22. Therefore, the host 10 and the pen holder 227 together cover the keyboard body 21. The dimension of the keyboard body 21 in the X-direction can be the same as or similar to the sum of the dimension of the pen holder 227 in the X-direction and the dimension of the host 10 in the X-direction. Therefore, the addition of the pen holder 22 to the keyboard bracket 22 can adaptively increase the width (X-direction dimension) of the keyboard body 21. The increased area of ​​the keyboard body 21 can increase the contact area between the keyboard body 21 and the supporting surface. A larger contact area can provide more stable support for the electronic device 100, helping to prevent slippage or tipping due to accidental touch or movement during use, and protecting the electronic device 100 from damage.

[0334] The increased width of the keyboard body 21 allows for a larger area on the keyboard 20 to accommodate the key clusters 213 and touchpad 214. The larger key clusters 213 in the electronic device 100 result in larger, more evenly spaced keys with a traditional layout, making operation more convenient for users with specific key preferences and effectively reducing accidental keystrokes and typing fatigue. The increased keyboard area also typically means more reasonable spacing between adjacent keys, which helps users type more accurately, thereby improving typing speed and accuracy.

[0335] The larger touchpad 214 means a larger operating area for the user, making it easier to perform various gesture operations such as swiping, zooming, and rotating, thus improving the convenience and flexibility of operation. When handling editing tasks or dragging and dropping files, the larger touchpad 214 can bring a smoother and more efficient operating experience.

[0336] Furthermore, the keyboard stand 22 provided in this embodiment is only connected to the host stand 13 of the host 10. The keyboard stand 22 only covers a portion of the surface of the host 10. Compared to commonly used electronic devices where the keyboard stand covers the entire surface of the host, the keyboard stand 22 of this application is smaller, which is beneficial for the miniaturization and weight reduction of the keyboard 20. The miniaturized and lightweight keyboard 20 makes it more convenient to carry. When going out or traveling, users can easily put the keyboard 20 into a backpack or handbag without adding too much weight or taking up too much space.

[0337] Only a portion of the surface of the host 10 (the first area 1103 of the non-display surface 1102) is covered by the keyboard bracket 22, while the other portion of the surface of the host 10 is exposed relative to the keyboard bracket 22, thus creating a difference from the form of the electronic device 100 in the prior art, so that users can feel a unique appearance and improve the user experience.

[0338] Furthermore, the second pen slot 2273 and the first pen slot 2115 together form a space for accommodating the stylus. When the keyboard bracket 22 is open, the second pen slot 2273 moves away from the first pen slot 2115, thus exposing the stylus for easy access by the user. After using the stylus, the user can directly place it in the second pen slot 2273 without any further alignment, simplifying the user's operation. When the user closes the keyboard bracket 22, the walls of the first pen slot 2115 and the second pen slot 2273 automatically align to limit the stylus, preventing it from falling off the keyboard.

[0339] During the opening process of the electronic device 100, firstly, the first fixing member 2312 and the second fixing member 2313 in the torque unit 231 rotate relative to each other to open the keyboard bracket 22. Then, the rotating member 122 in the second pivot assembly 12 rotates relative to the pivot base 121 to open the host bracket 13.

[0340] Specifically, please refer to Figures 37, 38, and 39. Figure 37 is a structural schematic diagram of the electronic device 100 shown in Figure 1 in its initial state. Figure 38 is a structural schematic diagram of the electronic device 100 in its first state. Figure 39 is a structural schematic diagram of the electronic device 100 in its second state. The electronic device 100 includes an initial state, a first state, and a second state.

[0341] For ease of understanding, in the initial state, the keyboard support 22 and the host support 13 of the electronic device 100 are both closed. In the first state, the keyboard support 22 and the host support 13 of the electronic device 100 are both open. In the second state, both the keyboard support 22 and the host support 13 of the electronic device 100 are both open.

[0342] Specifically, in the initial state, the electronic device 100 is in a closed state, and the keyboard bracket 22 is also in a closed state. The third magnetic element 1141 of the main unit bracket 13 and the fourth magnetic element 222 of the keyboard bracket 22 are magnetically attracted to each other, with a first distance between them. The fifth magnetic element 1142 of the main unit 11 and the sixth magnetic element 133 of the main unit bracket 13 are magnetically attracted to each other, with a third distance between them. When the electronic device 100 is subjected to an external force F0, it changes from the initial state to the first state. At this time, the external force can act on the main unit 11.

[0343] Both the host 10 and the keyboard 20 are constrained by magnetic attraction.

[0344] During the transition of the electronic device 100 from its initial state to its first state, the keyboard bracket 22 rotates relative to the keyboard body 21, and the angle between the keyboard bracket 22 and the keyboard body 21 rotates to the second preset angle α2 described above, so that the keyboard bracket 22 is in the open state. This causes the second fixing member 2313 of the torque unit 231 to rotate relative to the first fixing member 2312. The positioning structure 2336 of the second fixing member 2313 abuts against the limiting protrusion 2326 of the spindle 2311. During this process, the second rotating shaft assembly 12 does not rotate, so that the main unit bracket 13 is in the closed state.

[0345] During the process of electronic device 100 changing from the initial state to the first state, equations 1, 2, and 3 are satisfied:

[0346] Equation 1: Fc*L+M2>M1.

[0347] Equation 2: Fb*L+M2>M1.

[0348] Equation 3: Fb > Fc.

[0349] in:

[0350] Fa is the sum of the magnetic attraction forces of the fourth magnetic element 222 of the keyboard bracket 22 and the seventh magnetic element 132 of the host bracket 13, and the first magnetic element 223 of the keyboard bracket 22 and the third magnetic element 1141 of the host 10.

[0351] Fb represents the magnetic attraction between the eighth magnetic component 224 of the keyboard bracket 22 and the sixth magnetic component 133 of the host bracket 13.

[0352] Fc is the magnetic attraction between the sixth magnetic component 133 of the main unit bracket 13 and the fifth magnetic component 1142 of the main unit body 11.

[0353] L represents the width of the main unit bracket 13. In other words, L is the dimension of the main unit bracket 13 in the X direction.

[0354] M1 is the torque used when the keyboard bracket 22 is opened. M1' is the torque used when the keyboard bracket 22 is closed.

[0355] M2 is the torque during the opening process of the main unit bracket 13, and M2' is the torque during the closing process of the main unit bracket 13. The torques during the opening and closing processes of the main unit bracket 13 can be the same.

[0356] During the transition of the electronic device 100 from the first state to the second state, the shape of the torque unit 231 remains unchanged, and the keyboard bracket 22 remains open. The shape of the second pivot assembly 12 changes. The angle between the main unit bracket 13 and the main unit body 11 changes. The slider 1134 of the stop assembly 113 slides within the slide rail of the first fixed seat 1131. One end of the connecting rod 1133 rotates around the first pin 1135 in the first rotation clearance groove 1173 of the slider 1134. The other end of the connecting rod 1133 rotates around the second pin 1136 within the second rotation clearance groove 1182 of the second fixed seat 1132. The angle of the connecting rod 1133 relative to the first fixed seat 1131 changes. The second fixed seat 1132 moves out of the groove 1161 of the first fixed seat 1131. At this time, the magnetic element 114 in the stop block 1138 can be pushed away from the first magnetic element 223 by the repulsive force of the first magnetic element 223 of the keyboard bracket 22, compressing the elastic element 1137 and causing the stop body 1184 to move into the stop block through groove 1162 of the first fixed seat 1131. At this time, the stop body 1184 can block the slider 1134 from continuing to slide in the groove 1161, thereby stopping the relative position of the first fixed seat 1131 and the second fixed seat 1132 from changing, and thus keeping the host bracket 13 and the host body 11 at a certain angle.

[0357] At this time, the host bracket 13 is in the open state. The distance between the third magnetic element 1141 of the host body 11 and the fourth magnetic element 222 of the keyboard bracket 22 is the second distance. The second distance is greater than the first distance. The distance between the sixth magnetic element 133 of the host bracket 13 and the fifth magnetic element 1142 of the host body 11 is the fourth distance. The fourth distance is greater than the third distance. The angle between the host bracket 13 and the host body 11 can be a predetermined angle, that is, the user's preferred angle when the electronic device 100 is in the unfolded state. Furthermore, it is ensured that Fb is large enough during the opening process of the host bracket 13 to prevent the host bracket 13 from detaching from the keyboard bracket 22.

[0358] During the transition of electronic device 100 from the first state to the second state, equations 4 and 5 are satisfied:

[0359] Equation 4: Fb*L>M2.

[0360] Equation 5: Fb*L>M2+Fc*L.

[0361] When the electronic device 100 is in its second state, the main unit 10 opens to achieve a floating effect for user use. Since the third magnetic component 1141 and the fifth magnetic component 1142 of the main unit 11 are far from the main unit support 13 and the keyboard support 22, there is almost no magnetic attraction between the third magnetic component 1141 and the fifth magnetic component 1142 and the main unit support 13 and the keyboard support 22. At this time, the magnetic attraction between the main unit 10 and the keyboard support 22 is less than the magnetic attraction between the main unit 10 and the keyboard 20 in the initial state. Therefore, in the second state, the main unit 10 of the electronic device 100 can be detached from the keyboard support 22 with a small external force, allowing the user to use the main unit 10 independently.

[0362] Furthermore, after the host 10 is separated from the keyboard bracket 22, the magnetic component 114 of the keyboard bracket 22 moves away from the host 10. Therefore, the magnetic component 114 of the stop assembly 113 on the host 10 is not subject to the repulsive force of the magnetic component 114 of the keyboard bracket 22. Under the action of the elastic component, the stop block 1138 is lifted from the stop block through groove 1162 of the first fixed seat 1131. At this time, the slider 1134 can slide freely along the sliding groove 1161 of the first fixed seat 1131, so that the host bracket 13 can continue to open to a larger angle relative to the host body 11.

[0363] During the transition of electronic device 100 from the second state to the first state, due to the large closing torque of keyboard bracket 22, the angle between the main unit 11 and the main unit bracket 13 gradually decreases under the action of external force, so that the main unit bracket 13 is in the closed state. Furthermore, during the closing process of the main unit bracket 13, Fa needs to be large enough to prevent the main unit 10 from detaching from the keyboard bracket 22 under the action of external force.

[0364] During the transition of electronic device 100 from the second state to the first state, relation 6 is satisfied:

[0365] Equation 6: M2' < Fa*L.

[0366] During the transition of the electronic device 100 from the first turntable to its initial state, under the continued action of external force, the angle between the keyboard bracket 22 and the keyboard body 21 gradually decreases, so that the keyboard body 21 is in a closed state. Furthermore, during the closing process of the keyboard bracket 22, Fa needs to be large enough to prevent the host 10 from detaching from the keyboard bracket 22 under the action of external force.

[0367] During the process of electronic device 100 changing from the first state to the initial state, relation 7 is satisfied:

[0368] Equation 7: M1' < Fa*L.

[0369] The design of the magnetic force of the magnetic component 114 of the keyboard bracket 22, the magnetic force of the magnetic component 114 of the host bracket 13, the magnetic force of the magnetic component 114 of the host body 11, the torque of the keyboard bracket 22, and the torque of the host bracket 13 allows the keyboard bracket 22 and the host bracket 13 to act sequentially. This makes the opening and closing process of the keyboard bracket 22 and the host bracket 13 of the electronic device 100 more in line with user habits, thereby improving the user experience.

[0370] In addition, the aforementioned magnetic component 114 can utilize the fragmented space of the electronic device 100. The magnetic components 114 of the keyboard bracket 22, the host bracket 13, and the host body 11, while connecting the keyboard 20 and the host 10, utilize the fragmented space of the keyboard bracket 22 or the host 10, thus completing the detachable connection between the keyboard 20 and the host 10 without increasing the volume of the keyboard 20 and the host 10.

[0371] It should be noted that the above description of the structure of the keyboard 20 is only an example. In addition to the keyboard 20 provided in the first embodiment, this application also provides a second embodiment of the keyboard 20 to provide another possible design for the appearance of the keyboard 20.

[0372] Please refer to Figures 40 and 41. Figure 40 is a structural schematic diagram of the second embodiment of the keyboard 20 shown in Figure 1. Figure 41 is an exploded schematic diagram of the keyboard 20 shown in Figure 40. The keyboard 20 of the second embodiment differs from the keyboard 20 of the first embodiment in that the length of the hinge cover 226 of the keyboard 20 of the second embodiment is greater than the length of the hinge cover 226 of the first embodiment.

[0373] In this embodiment, the first pivot receiving groove 2112 of the keyboard housing 211 of the keyboard body 21 extends along the Y direction. The two ends of the first pivot receiving groove 2112 opposite to each other along the Y direction can extend to two surfaces of the keyboard housing 211 opposite to each other along the Y direction.

[0374] The second pivot accommodating groove 2210 of the second bracket 221 extends along the Y direction. The two ends of the second pivot accommodating groove 2210 that are opposite to each other along the Y direction can extend to the two surfaces of the second bracket 221 that are opposite to each other along the Y direction.

[0375] When the keyboard bracket 22 is in the closed state, the second hinge receiving groove 2210 and the first hinge receiving groove 2112 are opposite to each other in the Z direction and together form the receiving space of the first hinge assembly 23.

[0376] Please refer to Figure 42, which is a cross-sectional view of the keyboard 20 shown in Figure 40 at the CC position. The first fixing member 2312 of the torque unit 231 is located in the first pivot receiving groove 2112 of the keyboard housing 211 and the second pivot receiving groove 2210 of the second bracket 221. The first fixing member 2312 is provided with a pivot cover relief groove 2310. The pivot cover relief groove 2310 is recessed from the first fixing member 2312 in the opposite direction to the Z direction.

[0377] The cross-section of the pivot cover 226 can be U-shaped. The middle part of the pivot cover 226 protrudes in the opposite direction of the X direction, and the two opposite edges of the pivot cover 226 extend in the X direction along the Z direction.

[0378] The hinge cover 226 is located within the first hinge receiving groove 2112 of the keyboard housing 211 and the second hinge receiving groove 2210 of the second bracket 221. The hinge cover 226 covers the opening of the first hinge receiving groove 2112 facing the opposite direction in the X direction, the opening of the second hinge receiving groove 2210 facing the opposite direction in the X direction, and the first hinge assembly 23. The hinge cover 226 protrudes in the opposite direction in the X direction relative to the second bracket 221 and the keyboard housing 211, and forms the appearance surface of the keyboard 20 facing the opposite direction in the X direction.

[0379] When the keyboard bracket 22 is in the open position, the hinge cover 226 rotates, and one edge of the hinge cover 226 can slide into the hinge cover relief groove 2310 of the first fixing member 2312.

[0380] In this embodiment, the surface of the hinge cover 226 facing away from the first hinge assembly 23 can be the exterior surface of the keyboard 20 facing the X direction. Compared to the keyboard 20 of the first embodiment, the exterior surface of the keyboard 20 facing the opposite direction of the X direction in the second embodiment is simpler, improving the overall aesthetics and appearance harmony of the keyboard 20.

[0381] Please refer to Figure 43, which is a structural schematic diagram of the keyboard 20 according to a third embodiment of this application. In this embodiment, the structure of the hinge area of ​​the keyboard 20 is different from that of the hinge area of ​​the keyboard 20 in the first embodiment.

[0382] Specifically, please refer to Figures 44 and 45. Figure 44 is an exploded view of the keyboard 20 shown in Figure 43. Figure 45 is a structural schematic diagram of the keyboard body connector 2382 shown in Figure 44. The keyboard 20 includes a keyboard body 21, a keyboard support 22, and a first hinge assembly 23. The keyboard body 21 and the keyboard support 22 are rotatably connected via the first hinge assembly 23.

[0383] The specific structure of the keyboard body 21 can be referred to the description of the specific structure of the keyboard body 21 in the first embodiment above. This application will not elaborate on the structure of the keyboard body 21 here.

[0384] The first hinge assembly 23 includes at least two torque units 231, a keyboard bracket connector 2381, a keyboard body connector 2382, and a pen slot cover 2383. The torque range of the first hinge assembly 23 can be distributed among the torque ranges of multiple torque units 231. The sum of the torque ranges of the multiple torque units 231 can be the size of the required torque range for the entire first hinge assembly 23.

[0385] Referring again to Figure 45, the keyboard body connector 2382 includes a hinge receiving portion 2384 and a fixing portion 2385. There can be two hinge receiving portions 2384.
