Description

Technical Field

[0001] The present application relates to the technical field of terminal equipment, and in particular to a hinge mechanism and an electronic device. Background Art

[0002] Foldable electronic devices (eg, laptop computers) are more popular among users due to their portability.

[0003] The notebook computer includes a display part and a keyboard part. The display part and the keyboard part are rotatably connected via a hinge mechanism so that the display part can rotate relative to the keyboard part to achieve folding.

[0004] However, the overall structure of the hinge mechanism of existing laptop computers is complex, which makes disassembly, assembly and maintenance difficult. Summary of the Invention

[0005] The embodiments of the present application provide a hinge mechanism and an electronic device, which are used to solve the problem that the hinge mechanism of an existing laptop computer has a complex structure, resulting in difficulty in disassembly, assembly and maintenance.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, a pivot mechanism is provided, comprising a base, a rotating seat, and a baffle. The base is fixedly connected to a first component. The rotating seat is fixedly connected to a second component. The rotating seat has an inner surface and an outer surface. The rotating seat is rotatably connected to the base, and the rotation axis of the rotational connection between the rotating seat and the base is located on one side of the inner surface of the rotating seat. The baffle is disposed on one side of the outer surface of the rotating seat and is connected to the rotating seat. A wire passage is formed between the baffle and the rotating seat, and the wire passage extends around the rotation axis.

[0008] For example, the hinge mechanism can be applied to an electronic device, which may be a laptop computer. The first component may be the keyboard portion of the laptop computer, and the second component may be the display portion of the laptop computer, so that the laptop computer can be rotated between a folded state and an unfolded state through the hinge mechanism.

[0009] In the hinge mechanism provided in the first aspect of the present application, the cable passage can be used to accommodate a flexible connector (e.g., an FPC board) between the first component and the second component, thereby achieving electrical connection between the display portion and the keyboard portion via the FPC board. The baffle can thus shield and effectively protect the flexible connector.

[0010] Furthermore, the baffle is located on one side of the outer surface of the rotating base, allowing it to be exposed as a visual component when the electronic device is in the unfolded state, shielding the rotating base and the flexible connector. Since the baffle is an independent structural component, aesthetically pleasing processing of the baffle can enhance the overall aesthetics of the electronic device.

[0011] Moreover, when the flexible connector needs to be repaired or replaced, only the baffle can be removed to expose the flexible connector for easy repair or replacement. During the disassembly process, the entire shaft mechanism does not need to be disassembled, thereby reducing the difficulty of disassembly.

[0012] In one possible implementation of the first aspect of the present application, a wire groove is defined on the outer surface of the rotating base, forming a wire passage between the rotating base and the baffle. In this configuration, the baffle is attached to the outer surface of the rotating base, so that the baffle and the inner wall of the wire groove enclose the wire passage, resulting in a simpler structure and easier processing and installation.

[0013] In one possible implementation of the first aspect of the present application, a receiving groove is defined on the outer surface of the rotating base, a wire-passing groove is defined on the bottom surface of the receiving groove, and a baffle is disposed within the receiving groove. Thus, disposing the baffle within the receiving groove increases the contact area between the baffle and the rotating base, thereby enhancing the connection strength therebetween and improving the reliability of the overall structure.

[0014] In a possible implementation of the first aspect of the present application, the outer wall of the baffle is flush with the outer surface of the rotating base. In this structure, the baffle can be prevented from protruding from the outer surface of the rotating base, which is conducive to improving the aesthetics.

[0015] In a possible implementation of the first aspect of the present application, the baffle covers the outer surface of the rotating base. In this structure, when the electronic device is in the unfolded state, the outer surface of the rotating base is completely covered, with only the baffle exposed as an external appearance component, which is conducive to improving the aesthetics.

[0016] In one possible implementation of the first aspect of the present application, the rotating base further comprises two side walls that are spaced apart from each other, the side walls of the rotating base being connected between the outer surface of the rotating base and the inner surface of the rotating base; and the baffle covers the two side walls of the rotating base. In this structure, the baffle wraps around the exposed portion of the rotating base, thereby integrating the exposed portion of the rotating shaft mechanism, which further enhances the overall aesthetics.

[0017] In a possible implementation of the first aspect of the present application, the baffle is detachably connected to the rotating seat, which is conducive to further reducing the difficulty of disassembling the baffle, that is, reducing the difficulty of disassembling and installing the flexible connector.

[0018] In one possible implementation of the first aspect of the present application, a snap-fit ​​hole is provided on one of the baffle plate and the rotating seat, and a snap-fit ​​protrusion is provided on the other of the baffle plate and the rotating seat, the snap-fit ​​protrusion being snap-fitted into the snap-fit ​​hole. For example, the snap-fit ​​structure may be provided at both ends of the rotating seat's rotation axis in a circumferential direction, and the snap-fit ​​structure may be provided on both side walls of the rotating seat, so that four sets of snap-fit ​​structures are provided between the rotating seat and the baffle plate.

[0019] In this way, two sets of clamping structures are arranged between each side wall of the rotating seat and the baffle, that is, the rotating seat is provided with clamping structures on both sides of the axial direction of the rotating axis, and the clamping structures are provided at both ends along the circumferential direction of the rotating axis, so as to ensure that the force is balanced when the rotating seat and the baffle are clamped and fixed, which is conducive to improving the connection reliability between the two.

[0020] In a possible implementation of the first aspect of the present application, the rotating seat includes an arc-shaped portion and a connecting portion, the axis of the arc-shaped portion is parallel to the rotation axis, the connecting portion is arranged at the end of the arc-shaped portion along the circumferential direction, the connecting portion is used to be fixedly connected to the second component, the arc-shaped portion is rotatably connected to the base, and the surface of the arc-shaped portion away from the axis is the outer surface.

[0021] In this way, the arc portion is used to form a wire passage between the above-mentioned baffle, and the connecting portion can be fixedly connected to the structural member of the above-mentioned display part. For example, the connecting portion can extend between the display screen of the display part and the upper cover, and be fixedly connected to the upper cover.

[0022] In one possible implementation of the first aspect of the present application, the hinge mechanism further includes a pressure plate, the connecting portion being fixedly connected to the pressure plate, and the pressure plate being fixedly connected to the second component. This structure reduces the volume of the connecting portion and increases the contact area between the pressure plate and the second component. This improves the overall connection strength and reduces the difficulty of installing the hinge mechanism.

[0023] In one possible implementation of the first aspect of the present application, the pressure plate includes a first plate and a second plate. The first plate has a second plate on both sides of the arcuate portion along an axial direction. The connecting portion is fixedly connected to the first plate, and the second plate is fixedly connected to the second component. Specifically, the second plate increases the contact area between the connecting portion and the second component, thereby improving the overall connection strength.

[0024] In one possible implementation of the first aspect of the present application, a shaft hole is defined in one of the base and the rotating base, and a rotating shaft is provided in the other of the base and the rotating base, which is inserted into the shaft hole. This structure simplifies the rotating shaft mechanism and reduces the number of parts, thereby reducing the overall size of the rotating shaft mechanism and contributing to the thinness and lightness of the electronic device.

[0025] In one possible implementation of the first aspect of the present application, the rotating shaft and the shaft hole have an interference fit. This allows the friction generated between the rotating seat and the base during relative rotation to form a damping force during rotation of the rotating shaft mechanism. This allows the display portion of the electronic device to remain in any position relative to the keyboard portion when the display portion rotates relative to the keyboard portion, thereby adapting to different user habits and usage scenarios.

[0026] In a possible implementation of the first aspect of the present application, the rotating seat includes an arc-shaped portion and an extension portion, the axis of the arc-shaped portion is parallel to the axial direction of the rotating shaft, and along the circumference of the arc-shaped portion, the first end of the arc-shaped portion is used to be fixedly connected to the second component, the extension portion is arranged at the second end of the arc-shaped portion and extends in a direction close to the axis of the arc-shaped portion, the rotating shaft is fixed on the extension portion, and the shaft hole is opened on the base.

[0027] Under this structure, the rotating shaft is fixed on the extension part, and the rotating shaft and the arc-shaped part can be arranged coaxially, so that the arc-shaped part rotates around its own axis when rotating, which is beneficial to reducing the diameter of the circular motion trajectory formed during the rotation of the arc-shaped part, thereby reducing the space volume occupied by the rotating shaft mechanism during the rotation process, and further beneficial to reducing the space occupied in the electronic device, which is beneficial to the lightweight and thinning of the electronic device.

[0028] In one possible implementation of the first aspect of the present application, two extensions are provided, distributed axially along the arcuate portion. A rotating shaft is disposed on each extension, coaxially disposed between the two extensions, and inserted into an axial hole in the base. With this structure, the rotating base is provided with a rotating shaft on both axial sides, which facilitates force balance and improves structural reliability.

[0029] In one possible implementation of the first aspect of the present application, two bases are provided, distributed on either side of the rotating base along a direction parallel to the rotation axis. Axle holes are defined in the bases, and a rotating shaft is fixed to the rotating base, with both ends of the rotating shaft extending into the shaft holes of the two bases. In this configuration, both bases are fixed to the first component, and the two rotating shafts can be inserted into the corresponding shaft holes of the two bases, thereby facilitating overall force balance.

[0030] In a possible implementation of the first aspect of the present application, the base includes a support base and a fixed base, an axial hole is provided on the fixed base, a through hole is provided on the support base, and the fixed base is fixedly connected to the support base; the rotating shaft is fixed to the rotating base, and the rotating shaft is inserted into the through hole and the axial hole. Under this structure, the support base can be first installed in the first component. Since there is no interference between the through hole and the rotating shaft, the rotating base and the support base can be rotatably connected by inserting the rotating shaft into the through hole. The axial hole of the fixed base is then sleeved on the end of the rotating shaft to provide a damping force. This helps to reduce the difficulty of installing the rotating shaft mechanism inside the electronic device.

[0031] In one possible implementation of the first aspect of the present application, two fixing seats are provided, one on each side of the support seat along the axial direction of the rotating shaft, and the other ends of the rotating shaft are respectively inserted into the axial holes of the two fixing seats. In this structure, damping force can be generated on both sides of the rotating shaft along the axial direction, which is conducive to force balance.

[0032] In one possible implementation of the first aspect of the present application, the support base includes a first portion and two second portions, the two second portions being arranged parallel to the rotation axis and fixed to the ends of the first portion, each of the two second portions having a through hole, and the ends of the rotating shaft being inserted into the through holes of the two second portions. In this way, the space enclosed by the first and second portions of the support base can accommodate the portion of the rotating base on which the rotating shaft is disposed, thereby facilitating improved integration of the rotating shaft mechanism formed by the base and the support base, that is, further reducing the overall volume of the rotating shaft mechanism, thereby facilitating a thinner and lighter electronic device.

[0033] In one possible implementation of the first aspect of the present application, the support base further includes a third portion, the third portion being fixed to surfaces of the two second portions facing away from each other, and the third portion being configured to be fixedly connected to the first component. Thus, the third portion is provided on both symmetrical sides of the two second portions, thereby ensuring a more balanced overall force when the base is fixed to the first component, thereby improving the reliability of the connection between the base and the first component.

[0034] In a possible implementation of the first aspect of the present application, the rotating seat includes the above-mentioned arc-shaped portion and the above-mentioned extension portion, the axis of the arc-shaped portion is parallel to the rotation axis between the rotating seat and the base, and along the circumference of the arc-shaped portion, the first end of the arc-shaped portion is used to be fixedly connected to the second component, the extension portion is arranged at the second end of the arc-shaped portion, and extends in a direction close to the axis of the arc-shaped portion, and a limiting structure is arranged between the extension portion and the second portion.

[0035] The rotating seat can rotate between a first position and a second position relative to the supporting seat. When the rotating seat is in the first position, at least a portion of the arc portion is located between the two second portions; when the rotating seat is in the second position, the arc portion is located outside the two second portions, and the limiting structure can prevent the rotating seat from continuing to rotate in the direction from the first position to the second position.

[0036] For example, in the case where the electronic device is the above-mentioned laptop computer, during the process of the above-mentioned display part rotating away from the keyboard part, the limiting structure can prevent the display part from excessively rotating to avoid damage.

[0037] In one possible implementation of the first aspect of the present application, the limiting structure includes a limiting protrusion and a limiting groove, one of which is disposed on the extension portion, and the other of which is disposed on the second portion. When the rotating seat is in the first position, the limiting protrusion is separated from the limiting groove; when the rotating seat is in the second position, the limiting protrusion abuts within the limiting groove. In other words, the abutment between the limiting protrusion and the limiting groove prevents excessive rotation between the rotating seat and the base, thereby improving the reliability of the overall structure.

[0038] In one possible implementation of the first aspect of the present application, two extensions are provided, and the two extensions are distributed along the axial direction of the arc-shaped portion. The two extensions are provided corresponding to the two second portions, and a limiting structure is provided between each extension and the corresponding second portion. This structure is conducive to ensuring balanced force, thereby further improving the limiting effect.

[0039] In one possible implementation of the first aspect of the present application, the axial hole radially penetrates the surface of the base or rotating seat to form an opening. The width of the opening, along a direction perpendicular to the axial direction of the axial hole, is smaller than the diameter of the rotating shaft, and a portion of the rotating shaft is located within the opening. For example, along the thickness direction of the electronic device, the axial hole may radially penetrate the upper surface of the rotating seat so that the highest point of the rotating shaft is flush with the highest point of the rotating seat, or the highest point of the rotating shaft may be higher than the highest point of the rotating seat.

[0040] In this way, the shaft strength can be ensured without reducing the shaft diameter, and the size of the shaft mechanism along the thickness direction of the electronic device can be reduced, thereby facilitating the thinning of the electronic device.

[0041] In one possible implementation of the first aspect of the present application, at least one annular groove is formed on the portion of the rotating shaft that extends into the shaft hole. In this structure, lubricating material can be added to the annular groove to make the rotation smoother, reduce wear, and improve the user experience.

[0042] In a possible implementation of the first aspect of the present application, the axis of the shaft hole and the axis of the rotating shaft do not overlap with each other. In this structure, the rotating shaft and the shaft hole are eccentrically arranged to reduce the risk of the rotating shaft falling out of the opening.

[0043] In one possible implementation of the first aspect of the present application, the axis of the shaft hole and the axis of the rotating shaft are arranged perpendicular to the mounting surface of the base and the first portion. The opening is provided on the upper surface of the rotating base along the thickness of the electronic device, thereby further reducing the risk of the rotating shaft falling out.

[0044] In a second aspect, an electronic device is provided, comprising a keyboard portion, a display portion, and a hinge mechanism. The hinge mechanism is the hinge mechanism described in any of the above technical solutions, wherein the base of the hinge mechanism is fixedly connected to the keyboard portion, and the rotating base of the hinge mechanism is fixedly connected to the display portion.

[0045] The electronic device provided in the second aspect of the present application, because it includes the rotating shaft mechanism described in any of the above technical solutions, can solve the same technical problems and achieve the same technical effects.

[0046] In one possible implementation of the second aspect of the present application, the keyboard portion includes a first region and a second region, wherein the thickness of the first region is smaller than the thickness of the second region. When the display portion and the keyboard portion are interlocked, the display portion and the first region are stacked. In this structure, the maximum thickness of the electronic device can be the thickness of the second region, thereby facilitating a thinner and lighter electronic device.

[0047] In one possible implementation of the second aspect of the present application, an interface module is disposed within the keyboard portion, with a socket for the interface module disposed on a side wall of the keyboard portion parallel to and proximate to the axis of the hinge mechanism. In this manner, the interface module does not affect the thickness of the first region, thereby facilitating a thinner and lighter electronic device.

[0048] Alternatively, the thickness of the keyboard portion may gradually decrease along the width direction from the rear side (the side close to the hinge mechanism) to the front side (the side away from the hinge mechanism), which is also conducive to making the electronic device lighter and thinner.

DETAILED DESCRIPTION

[0074] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0075] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0076] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0077] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0078] The present application provides an electronic device that is a foldable terminal device. For example, the electronic device may be a laptop computer, a foldable mobile phone, or a tablet computer. The following embodiments are described using a laptop computer as an example.

[0079] See also Figure 1 and Figure 2 , Figure 1 This is a structural diagram of the electronic device 01 (open state) provided in an embodiment of the present application. Figure 2 This is a structural diagram of an electronic device 01 (folded state) provided in an embodiment of the present application. The electronic device 01 may include a display portion 10 , a keyboard portion 20 , and a hinge mechanism 30 .

[0080] To facilitate the following description, an XYZ coordinate system is established, defining the width of electronic device 01 as the X-axis, the length of electronic device 01 as the Y-axis, and the thickness of electronic device 01 as the Z-axis. It should be noted that this coordinate system applies when electronic device 01 is in the folded state; when electronic device 01 is in the unfolded state, the keyboard portion 20 of electronic device 01 conforms to this coordinate system.

[0081] It is understandable that the coordinate system of the electronic device 01 can be flexibly set according to actual needs. This application only provides an example and cannot be considered as a special limitation of this application. Figure 1 and Figure 2 Only some components of the electronic device 01 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 1 and Figure 2 restrictions.

[0082] The display portion 10 is used to display images, videos, and the like. The display portion 10 may include an upper cover 11 and a display screen 12. The display screen 12 is secured to the upper cover 11, for example, by bonding, snapping, or other means. The display screen 12 is positioned on a side of the upper cover 11 proximate to the keyboard portion 20. The upper cover 11 may be made of either metal or plastic. Therefore, this application does not impose any particular restrictions on the material of the upper cover 11.

[0083] In addition, the display screen 12 may be a flexible display screen 12 or a rigid display screen 12. For example, the display screen 12 may be an organic light-emitting diode (OLED) display screen 12, an active-matrix organic light-emitting diode (AMOLED) display screen 12, a mini light-emitting diode (LED) display screen 12, a micro light-emitting diode (LED) display screen 12, a micro organic light-emitting diode (OLED) display screen 12, a quantum dot light-emitting diode (QLED) display screen 12, a liquid crystal display screen 12 (LCD), and the like.

[0084] The keyboard portion 20 is used to edit or perform other operations on the content displayed on the display screen 12. The keyboard portion 20 may include a keyboard 21, an upper shell 22, and a bottom shell 23. The keyboard 21 is fixed to the upper shell 22. The upper shell 22 and the bottom shell 23 are fixedly connected. For example, the upper shell 22 and the bottom shell 23 may be fixed together by bonding, snapping, threading, or welding. A storage space (not shown) is formed between the upper shell 22 and the bottom shell 23. This storage space is used to accommodate electronic components of the electronic device 01, such as the motherboard, CPU (central processing unit), graphics card, memory, fan, and interface module.

[0085] In addition, the keyboard 21 is electrically connected to the mainboard, and the display screen 12 is electrically connected to the mainboard via a flexible connector. For example, the flexible connector may be an FPC (Flexible Printed Circuit) board, so that the content displayed on the display screen 12 can be edited via the keyboard 21.

[0086] The hinge mechanism 30 connects the display portion 10 and keyboard portion 20, enabling relative rotation between them, thereby transitioning the electronic device 01 between the open and folded states. The axis of rotation of the hinge mechanism 30 is parallel to the Y-axis. When the electronic device 01 is in the open state, the display portion 10 rotates away from the keyboard portion 20, forming an angle between them and separating the display screen 12 and keyboard 21. In this state, the user can view content displayed on the display screen 12 and perform operations such as editing using the keyboard 21.

[0087] When electronic device 01 is folded, display portion 10 and keyboard portion 20 are interlocked, display screen 12 and keyboard 21 are positioned opposite each other, and both are located between upper cover 11 and bottom case 23, effectively protecting display screen 12 and keyboard 21. In this state, electronic device 01 forms a roughly rectangular plate-like structure, making it easy to carry.

[0088] In order to enhance the user experience, the hinge mechanism 30 can also provide damping force so that the display portion 10 of the electronic device 01 can be maintained at different positions during the opening process, thereby being able to adapt to the usage habits and different usage scenarios of different users, which is conducive to enhancing the user experience.

[0089] In addition, with the development trend of electronic devices 01 becoming thinner and lighter, higher requirements are placed on the structure and location of the rotating shaft mechanism 30. Figure 3 and Figure 4 , Figure 3 This is an exploded view of the electronic device 01 provided in an embodiment of the present application. Figure 4 This is a partial structural diagram of the electronic device 01 provided in an embodiment of the present application in a folded state.

[0090] In some embodiments, the keyboard portion 20 may include a first area 20a and a second area 20b, the first area 20a and the second area 20b are distributed along the X-axis direction, and the thickness dimension D1 of the first area 20a is smaller than the thickness dimension D2 of the second area 20b, and the keyboard 21 is located in the first area 20a, that is, along the Z-axis direction, the thickness D1 of the first area 20a is smaller than the thickness D2 of the second area 20b.

[0091] Furthermore, when the electronic device 01 is in the folded state, the display portion 10 is stacked with the first region 20a of the keyboard portion 20, i.e., the display portion 10 only covers the first region 20a of the keyboard portion 20. In some examples, the sum of the thickness D3 of the display portion 10 and the thickness D1 of the first region 20a can be equal to the thickness D2 of the second region 20b.

[0092] In this way, when the above-mentioned electronic device 01 is in a folded state, its maximum thickness is the thickness of the second area 20b. Therefore, the display part 10 is stacked on the keyboard part 20, and will not further increase the maximum thickness of the keyboard part 20. That is, the maximum thickness of the electronic device 01 is the thickness of the second area 20b.

[0093] Furthermore, the interface module can be disposed within the second region 20b of the keyboard portion 20. For example, the interface module can be a USB interface module or a Type-C interface module. The interface module's socket is disposed on the rear side of the keyboard portion 20 (i.e., along the X-axis, the second region 20b is away from the surface of the first region 20a). Since the interface module's socket size is standard and cannot be arbitrarily changed, disposing the interface module in the second region 20b ensures that the thickness of the first region 20a is not affected by the interface module. That is, the thickness of the first region 20a is not increased by the interface module, thereby facilitating a thinner and lighter electronic device 01.

[0094] In this embodiment, since the thickness D2 of the second region 20b is greater than the thickness D1 of the first region 20a, a step structure is formed at the junction of the first region 20a and the second region 20b. Therefore, the hinge mechanism 30 can be disposed at the junction of the first region 20a and the second region 20b of the keyboard portion 20.

[0095] For details, please refer to Figure 3 and Figure 4 , and refer to Figure 5 , Figure 5 A partial cross-sectional structural diagram of the keyboard portion 20 provided in an embodiment of the present application, wherein the upper surface of the keyboard portion 20 (i.e., the surface on which the keyboard 21 is provided) may include a first surface 20c and a second surface 20d, wherein the first surface 20c is located in the above-mentioned first area 20a, and the second surface 20d is located in the above-mentioned second area 20b. Since the second surface 20d is higher than the first surface 20c along the Z-axis direction, the first surface 20c and the second surface 20d are connected by a third surface, thereby forming a step structure.

[0096] In addition, a mounting opening 24 communicating with the accommodation space may be provided at the junction between the first surface 20c and the second surface 20d. Figure 3The hinge mechanism 30 shown can connect the keyboard portion 20 and the display portion 10 through the mounting opening 24 , thereby achieving a rotational connection between the keyboard portion 20 and the display portion 10 .

[0097] In other embodiments, the keyboard portion 20 may also have a structure with a gradually decreasing thickness. That is, along the X-axis, the thickness of the keyboard portion 20 gradually decreases from the rear side (the side away from the user when in use) to the front side (the side closer to the user when in use).

[0098] In this case, since the rear side of the keyboard portion 20 is thicker, the interface module can be placed there, with its socket located on the rear side of the keyboard portion 20. Furthermore, the interface module does not increase the thickness of the front side of the keyboard portion 20, thereby contributing to a slimmer and lighter electronic device 01. In this case, the hinge mechanism 30 can be located at the rear edge of the keyboard portion 20, thereby achieving a pivoting connection between the keyboard portion 20 and the display portion 10.

[0099] Therefore, the present application does not impose any particular limitation on the specific location of the hinge mechanism 30. In the following embodiments, the keyboard portion 20 includes the first area 20a and the second area 20b, and the hinge mechanism 30 is located at the junction of the first area 20a and the second area 20b.

[0100] On this basis, see Figure 6 , Figure 6 This is a partial cross-sectional structural diagram of the electronic device 01 provided in the embodiment of the present application. Figure 1 The keyboard portion 20 and the display portion 10 are electrically connected to each other through a flexible connector. Therefore, the flexible connector needs to extend from the accommodating space to the display screen 12, that is, when the electronic device 01 is in the unfolded state, at least part of the flexible connector is located outside the keyboard portion 20 and the display portion 10, that is, at least part of the flexible connector needs to be exposed.

[0101] To enhance aesthetics and effectively protect the flexible connector, in related art, the exposed portion of the flexible connector of electronic device 01 can be disposed within a hinge mechanism 30. This means that the exposed portion of the flexible connector is shielded and protected by the hinge mechanism 30. This protects the flexible connector while also shielding it, contributing to the overall aesthetics of electronic device 01. However, the hinge mechanism 30 in this electronic device 01 is complex, making disassembly difficult when the flexible connector needs to be repaired, impacting the user experience.

[0102] To solve the above problems, the present invention provides a hinge mechanism 30, which can be applied to the above electronic device 01. Figure 7 、 Figure 8 、 Figure 9 as well as Figure 10 , Figure 7 This is a structural diagram of a rotating shaft mechanism 30 provided in an embodiment of the present application. Figure 8 This is a partial cross-sectional structural diagram of a rotating shaft mechanism 30 provided in an embodiment of the present application installed in an electronic device 01. Figure 9 This is an exploded view of a rotating shaft mechanism 30 provided in an embodiment of the present application. Figure 10 This is a cross-sectional view of a rotating shaft mechanism 30 provided in an embodiment of the present application.

[0103] Specifically, the hinge mechanism 30 may include a base 100 and a rotating seat 200, the base 100 is fixedly connected to the keyboard part 20, that is, the base 100 is fixed in the above-mentioned accommodation space; the first end of the rotating seat 200 is fixedly connected to the display part 10, and the second end of the rotating seat 200 extends into the accommodation space through the above-mentioned mounting port 24, and is rotatably connected to the base 100, and the rotation axes of the two are parallel to the above-mentioned Y-axis direction, thereby enabling the keyboard part 20 and the display part 10 to be rotatably connected.

[0104] The rotating base 200 may have an inner surface 200b and an outer surface 200a. When the electronic device 01 is in the unfolded state (eg Figure 8 As shown), a portion of the rotating base 200 is rotated from the mounting opening 24 to the outside of the accommodation space. At this time, the rotating base 200 faces the surface of the keyboard portion 20 (ie Figure 8 The concave surface in the middle is the inner surface 200b, and the surface of the rotating base 200 away from the keyboard portion 20 is the outer surface 200a. The rotation axis between the rotating base 200 and the base 100 is located on one side of the inner surface 200b of the rotating base 200.

[0105] Also, please continue reading Figure 7-10 The hinge mechanism 30 also includes a baffle 300, which is arranged on one side of the outer surface 200a of the rotating base 200, and the baffle 300 is connected to the rotating base 200. A wire passage 400 is formed between the baffle 300 and the rotating base 200, and the wire passage 400 extends around the rotation axis between the rotating base 200 and the base 100. The wire passage 400 can be used to accommodate the above-mentioned flexible connector so that the flexible connector can extend from the display part 10 to the keyboard part 20.

[0106] In this way, the flexible connector is arranged inside the wire passage, thereby shielding and protecting the flexible connector. At the same time, the baffle 300 is located on the outer surface 200a of the rotating base 200. That is, when the electronic device 01 is in the unfolded state, the baffle 300 is exposed on the outside, forming an external appearance.

[0107] On the one hand, simply removing the baffle 300 exposes the flexible connector, facilitating repair or replacement. Furthermore, disassembly eliminates the need to completely disassemble the hinge mechanism 30, reducing the difficulty. On the other hand, since the baffle 300 is a visually appealing component and an independent structural element, it can be aesthetically pleasingly processed, thereby enhancing the overall aesthetics of the electronic device 01 and improving the user experience.

[0108] In some examples, the outer surface 200a of the rotating base 200 may be provided with a wire groove 201, which forms the wire passage 400 between the baffle 300 and the rotating base 200. That is, the wire passage 400 is formed between the baffle 300 and the inner wall of the wire groove 201, thereby preventing the flexible connector located in the wire groove 201 from being exposed.

[0109] Also, see Figure 11 and Figure 12 , Figure 11 This is an exploded view of a rotating seat 200 and a baffle 300 provided in an embodiment of the present application. Figure 12 for Figure 11 The assembly diagram of the rotating base 200 and the baffle 300 is provided. The outer surface 200a of the rotating base 200 can also be provided with a receiving groove 202. The wire groove 201 is provided on the bottom surface of the receiving groove 202, and the baffle 300 can be disposed within the receiving groove 202. Thus, placing the baffle 300 within the receiving groove 202 increases the contact area between the baffle 300 and the rotating base 200, thereby improving the connection strength between the two and enhancing the reliability of the overall structure.

[0110] For example, when the baffle 300 and the rotating base 200 are fixed by gluing, increasing the contact area between the two is beneficial to improving the bonding strength, thereby improving the connection strength between the baffle 300 and the rotating base 200.

[0111] Furthermore, the outer wall of the baffle 300 (ie, the surface away from the wire groove 201 ) can be flush with the outer surface 200 a of the rotating base 200 to prevent the baffle 300 from protruding from the outer surface 200 a of the rotating base 200 , thereby improving the overall appearance.

[0112] Alternatively, see Figure 13 , Figure 13This is another assembly diagram of a rotating base 200 and a baffle 300 provided in an embodiment of the present application. The baffle 300 can cover the outer surface 200a of the rotating base 200. For example, when the electronic device 01 is in the unfolded state, the baffle 300 can only cover the exposed portion of the outer surface 200a of the rotating base 200; alternatively, it can cover the entire outer surface 200a of the rotating base 200. In other words, the outer surface 200a of the rotating base 200 and the wire groove 201 on the outer surface 200a are both obscured by the baffle 300, allowing the baffle 300 to serve entirely as an exterior component, thereby enhancing the overall aesthetics.

[0113] Furthermore, the rotating base 200 further has two side walls 200 c that are separated from each other. The side walls 200 c of the rotating base 200 are connected between the inner surface 200 b and the outer surface 200 a of the rotating base 200 .

[0114] In some possible examples, the baffle 300 may also cover the two side walls 200c of the rotating base 200. In this way, the baffle 300 can cover the outer surface 200a of the rotating base 200 and the side walls 200c on both sides, so that the exposed portion of the rotating base 200 is completely enclosed by the baffle 300. While protecting the rotating base 200, the exposed portion of the rotating shaft mechanism 30 is integrated, hiding the gaps between the connected components, and thus further improving the overall aesthetics.

[0115] In other possible examples, the baffle 300 can be buckled onto the rotating base 200, and the baffle 300 is connected to the two side walls 200c of the rotating base 200, with the baffle 300 and the outer surface 200a of the rotating base 200 spaced apart, thereby forming the wire passage 400 between the baffle 300 and the rotating base 200. With this structure, it is possible to avoid grooving the outer surface 200a of the rotating base 200, which helps to reduce the number of process steps and ease the processing difficulty.

[0116] In some embodiments, the baffle 300 and the rotating base 200 may be detachably connected to further reduce the difficulty of disassembling the baffle 300. Figure 11 、 Figure 12 as well as Figure 13 The edge of the baffle 300 may be provided with a snap-fitting hole 310, and the side wall 200c of the rotating base 200 may be provided with a snap-fitting protrusion 203. The edge of the baffle 300 is bent so as to face the side wall 200c of the rotating base 200, and the snap-fitting protrusion 203 is snapped into the snap-fitting hole 310, thereby achieving the snap-fitting connection between the baffle 300 and the rotating base 200. Alternatively, the baffle 300 and the rotating base 200 may be connected by screws, that is, threaded holes are provided on the baffle 300 and the rotating base 200, so as to be locked and fixed.

[0117] In addition, the connection points between the baffle 300 and the rotating seat 200 can be set at the two circumferential ends along the above-mentioned rotation axis to hide the connection structure between the two (i.e., the snap-fit ​​protrusion 203 and the snap-fit ​​hole 310), which is conducive to further improving the overall aesthetics.

[0118] In other possible embodiments, the baffle 300 and the rotating base 200 may also be fixedly connected by bonding, welding, etc., thereby facilitating improving the connection strength between the two. Therefore, this application does not impose any special limitation on this.

[0119] Based on the above, please refer to Figure 14 and Figure 15 , Figure 14 This is an exploded view of the rotating seat 200, the baffle 300 and the pressure plate 500 provided in an embodiment of the present application. Figure 15 for Figure 14 An assembly diagram of the rotating base 200, the baffle 300, and the pressure plate 500 is provided. To facilitate installation of the rotating base 200, the rotating base 200 may include an arcuate portion 210 and a connecting portion 220. The axis of the arcuate portion 210 is parallel to the rotation axis (i.e., the rotation axis of the rotating base 200 and the base 100). The connecting portion 220 is provided at a first end of the arcuate portion 210 along the circumferential direction. The connecting portion 220 is used for fixed connection with the display portion 10, and the second end of the arcuate portion 210 is used for rotational connection with the base 100.

[0120] Specifically, after the second end of the arc portion 210 is rotatably connected to the base 100, the first end of the arc portion 210 and the connecting portion 220 can be rotated. Figure 8 The mounting opening 24 is rotated to the outside of the accommodation space. Then, the connecting portion 220 is fixedly connected to the display portion 10. For example, the connecting portion 220 and the upper cover 11 of the display portion 10 can be fixed by welding, bonding or bolting.

[0121] In some embodiments, due to the above Figure 8 The mounting opening 24 is shown to be provided on the upper shell 22 of the keyboard portion 20. That is, when the electronic device 01 is in the unfolded state, the mounting opening 24 of the upper shell 22 is exposed to the outside, and the user can directly see the mounting opening 24. Therefore, the smaller the size of the mounting opening 24, the more conducive to the overall aesthetics.

[0122] Based on this, please continue to refer to Figure 14 and Figure 15The hinge mechanism 30 may further include a pressing plate 500. The connecting portion 220 of the rotating base 200 is fixedly connected to the pressing plate 500, and the pressing plate 500 is fixedly connected to the upper cover 11 of the display portion 10. Specifically, the pressing plate 500 may include a first plate 510 and a second plate 520. The first plate 510 has a second plate 520 on both sides of the arc-shaped portion 210 along the axial direction. The connecting portion 220 is fixedly connected to the first plate 510, and the second plate 520 on both sides are fixedly connected to the upper cover 11.

[0123] This reduces the volume of the connecting portion 220 of the rotating base 200. At the same time, the contact area between the connecting portion 220 and the upper cover 11 is increased through the pressure plate 500, thereby improving the connection strength between the rotating base 200 and the upper cover 11. Furthermore, reducing the volume of the connecting portion 220 of the rotating base 200 facilitates a corresponding reduction in the size of the mounting opening 24 provided in the upper shell 22. Specifically, the size of the mounting opening 24 only needs to allow the rotating portion and the connecting portion 220 to rotate normally and pass through the mounting opening 24. Therefore, reducing the size of the mounting opening 24 further enhances the aesthetics of the electronic device 01.

[0124] During installation, the rotating base 200 is first rotatably connected to the base 100, and then the connecting portion 220 and the arc-shaped portion 210 of the rotating base 200 are rotated out of the accommodation space through the installation opening 24. Then, the pressing plate 500 is fixedly connected to the connecting portion 220, and finally, the pressing plate 500 is fixedly connected to the upper cover 11.

[0125] In some examples, the first plate 510 of the pressure plate 500 and the connecting portion 220, as well as the second plate 520 of the pressure plate 500 and the upper cover 11 of the display portion 10, can be fixed by bolting. Furthermore, to ensure the strength of the fixed connection, multiple connection points can be provided between the first plate 510 and the connecting portion 220, and between the second plate 520 and the upper cover 11. These multiple connection points should not be on the same straight line, thereby increasing the area over which the locking force of the multiple connection points acts, thereby improving the connection strength.

[0126] Furthermore, the baffle 300 is disposed on one side of the outer surface 200a of the rotating base 200, and the end of the baffle 300 can extend between the pressure plate 500 and the connecting portion 220, thereby further improving the connection reliability between the baffle 300 and the rotating base 200. Furthermore, the engaging structure between the baffle 300 and the rotating base 200, namely the engaging hole 310 and the engaging protrusion 203, can be disposed between the baffle 300 and the sidewall 200c of the connecting portion 220, thereby improving the connection reliability while concealing the engaging hole 310 and the engaging protrusion 203, thereby enhancing the overall aesthetics.

[0127] It can be understood that, since the connecting structure formed by the clamping holes 310 and the clamping protrusions 203 is arranged between the two end portions of the rotating seat 200 and the baffle 300, that is, the second end of the arc-shaped portion 210 away from the connecting portion 220 is also provided with the connecting structure, so that the baffle 300 and the rotating seat 200 are provided with four groups of clamping holes 310 and clamping protrusions 203, that is, four connecting points are formed, thereby facilitating force balance of the overall connecting structure.

[0128] Based on this, the above is a detailed description of the connecting structure of the rotating seat 200 and the display part 10. The connecting structure between the rotating seat 200 and the base 100 will be described in detail below. Please refer to Figure 16 and Figure 17 , Figure 16 the structure diagram of another rotating shaft mechanism 30 provided by the embodiment of the application, Figure 17 the exploded view of the rotating shaft mechanism 30 provided by Figure 16 .

[0129] Among them, the rotating seat 200 and the base 100 can be rotatably connected through the rotating shaft 240 and the shaft hole 110. That is, one of the base 100 and the rotating shaft 240 is provided with the shaft hole 110, and the other of the base 100 and the rotating shaft 240 is provided with the rotating shaft 240, and the rotating shaft 240 is inserted into the shaft hole 110, thereby realizing the rotatable connection between the rotating seat 200 and the base 100.

[0130] Specifically, the rotating seat 200 can further include an extension portion 230, which is arranged at the second end of the arc-shaped portion 210, that is, the end away from the connecting portion 220. Moreover, the extension portion 230 extends from the second end of the arc-shaped portion 210 to the direction close to the axis of the arc-shaped portion 210. The rotating shaft 240 can be fixed to the extension portion 230, and the shaft hole 110 can be arranged on the base 100. For example, the axis of the rotating shaft 240 can coincide with the axis of the arc-shaped portion 210 (that is, parallel to the Y-axis direction), that is, the arc-shaped portion 210 and the rotating shaft 240 are coaxially arranged.

[0131] In order to keep the force balance between the rotating seat 200 and the base 100 when they are rotatably connected. The extension portion 230 can be provided with two, which are distributed along the axial direction of the arc-shaped portion 210, and the rotating shaft 240 is arranged on each of the two extension portions 230, the two rotating shafts 240 are coaxially arranged, and the two extension portions 230 are arranged between the two rotating shafts 240, and the two rotating shafts 240 are inserted into the shaft hole 110 on the base 100. In this way, the arc-shaped portion 210 has a connecting structure for rotatable connection with the base 100 on both sides along its own axial direction, so that the two sides of the rotating seat 200 along the axial direction can be uniformly stressed, which is beneficial to improve the reliability of the overall structure.

[0132] Correspondingly, two of the above-mentioned bases 100 can be provided, and both bases 100 are fixed in the accommodation space of the keyboard part 20. The two bases 100 are distributed on both sides of the rotating seat 200 along the axial direction of the rotating shaft 240 (i.e., the Y-axis direction), so that the above-mentioned two rotating shafts 240 are respectively inserted into the corresponding shaft holes 110 on the base 100.

[0133] For example, the base 100 can be fixed to the bottom shell 23 or the upper shell 22 by bolts, thereby achieving a fixed connection between the base 100 and the keyboard portion 20. Alternatively, the base 100 can also be fixedly connected by welding, bonding, etc. Therefore, this application does not impose any special restrictions on the fixing method of the base 100.

[0134] In some examples, the rotating shaft 240 can be interference-fitted with the shaft hole 110. This allows the frictional force generated between the rotating base 200 and the base 100 during relative rotation to form a damping force for the rotating shaft mechanism 30 during rotation. This allows the display portion 10 of the electronic device 01 to remain at any position relative to the keyboard portion 20 when the display portion 10 rotates relative to the keyboard portion 20, thereby adapting to different user habits and usage scenarios.

[0135] Moreover, in the hinge mechanism 30 provided in the embodiment of the present application, the rotational connection between the display portion 10 and the keyboard portion 20 is realized only through the rotating seat 200 and the base 100, and the damping force is generated based on the interference fit between the hinge 240 and the shaft hole 110. The overall structure is simple and has fewer parts, which is beneficial to reducing the overall volume of the hinge mechanism 30 and is beneficial to making the electronic device 01 lighter and thinner.

[0136] For other examples, see Figure 16 and Figure 17 The shaft hole 110 can penetrate the surface of the base 100 in a radial direction to form an opening 111, and in a direction perpendicular to the axial direction of the shaft hole 110, the width of the opening 111 is smaller than the diameter of the rotating shaft 240, and a part of the rotating shaft 240 is located at the opening 111. For example, along the thickness direction of the electronic device 01 (i.e., the Z-axis direction), the shaft hole 110 can penetrate the upper surface of the base 100, and along the Y-axis direction, the width of the opening 111 is smaller than the diameter of the rotating shaft 240. In this way, the cross-section formed by the shaft hole 110 forms an incomplete circular structure, that is, the inner wall of the shaft hole 110 forms an arc surface with an arc center angle greater than 180° and less than 360°, so that the rotating shaft 240 and the shaft hole 110 can achieve a rotational connection while also helping to reduce the weight of the base 100.

[0137] Also, see Figure 18 , Figure 18 for Figure 16The provided structural diagram of the rotating shaft 240 of the rotating shaft mechanism 30 and the shaft hole 110 of the base 100 shows that a portion of the rotating shaft 240 can extend out of the shaft hole 110 through the opening 111, that is, along the Z-axis, the highest point of the rotating shaft 240 is higher than the highest point of the base 100. Alternatively, along the Z-axis, the highest point of the rotating shaft 240 is flush with the highest point of the base 100.

[0138] That is, along the Z-axis, the distance L1 from the highest point of the rotating shaft 240 to the bottom surface of the base 100 is greater than or equal to the height L2 of the base 100. This structure helps reduce the size of the base 100 along the Z-axis, thereby further reducing the thickness of the electronic device 01 while maintaining the diameter of the rotating shaft 240 and ensuring the strength of the rotating shaft 240.

[0139] In addition, in order to make the relative rotation of the rotating shaft 240 and the shaft hole 110 smoother, a lubricating material can be added between the rotating shaft 240 and the shaft hole 110 provided in the embodiment of the present application. Figure 19 , Figure 19 This is a structural diagram of a rotating shaft 240 provided in an embodiment of the present application. The rotating shaft 240 extends into Figure 17 At least one annular groove 241 is provided on the portion of the shaft hole 110 shown, and the annular groove 241 can be used to store lubricating material so that during the relative rotation of the rotating shaft 240 and the shaft hole 110, the lubricating material can cover the outer wall of the rotating shaft 240 and the inner wall of the shaft hole 110, thereby making the relative rotation between the shaft hole 110 and the rotating shaft 240 smoother and reducing wear, which is beneficial to improving the user experience.

[0140] For other possible examples, see Figure 20 , Figure 20 This is a structural diagram of a rotating shaft 240 and another type of shaft hole 110 provided in an embodiment of the present application. The axis of the rotating shaft 240 and the axis of the shaft hole 110 may not coincide with each other. For example, the cross-section of the rotating shaft 240 is circular, and the cross-section of the shaft hole 110 is elliptical, so that the axis of the rotating shaft 240 and the axis of the shaft hole 110 are distributed along the Z-axis direction.

[0141] In this structure, since the rotating shaft 240 and the shaft hole 110 are not coaxially arranged, that is, eccentrically arranged, there can be interference during the relative rotation between the two, which is beneficial to reducing the risk of the rotating shaft 240 falling out toward the opening 111 and improving the reliability of the overall structure.

[0142] In another embodiment, see Figure 21 and Figure 22 , Figure 21 This is a structural diagram of another rotating shaft mechanism 30 provided in an embodiment of the present application. Figure 22 for Figure 21An exploded view of the rotating shaft mechanism 30 is provided. The base 100 of the rotating shaft mechanism 30 may include a support base 120 and a fixed base 130. The above-mentioned shaft hole 110 is opened on the fixed base 130, and a through hole 120a is opened on the support base 120. The fixed base 130 is fixedly connected to the support base 120; the rotating shaft 240 is inserted into the through hole 120a and inserted into the shaft hole 110. During installation, the support base 120 is first fixed to the bottom shell 23 of the keyboard part 20, and then the rotating shaft 240 of the rotating base 200 is inserted into the through hole 120a on the support base 120. Since there is no interference between the through hole 120a and the rotating shaft 240, the rotating base 200 and the support base 120 can be rotated relative to each other by inserting the rotating shaft 240 into the through hole 120a. Then, the fixed base 130 is sleeved on the end of the rotating shaft 240 and fixedly connected to the support base 120. This makes installation simpler and more convenient, helping to reduce installation difficulty.

[0143] In which, the above-mentioned support seat 120 can include a first part 121 and two second parts 122, the two second parts 122 are distributed along a direction parallel to the axial direction of the rotating shaft 240 (that is, along the Y-axis direction), and are respectively fixed at both ends of the first part 121, and a through hole 120a is provided on the two second parts 122. The extension part 230 of the above-mentioned rotating seat 200 is arranged between the two second parts 122, and the two rotating shafts 240 are respectively inserted into the through holes 120a on the corresponding second parts 122.

[0144] For example, please refer to Figure 21 and Figure 22 The first portion 121 and the two second portions 122 are both flat-plate structures, and the first portion 121 and the second portion 122 are arranged perpendicular to each other. For example, the first portion 121 is parallel to the YZ plane, and the second portion 122 is parallel to the XZ plane. The first portion 121 and the second portion 122 can be fixed together by bonding, clamping, welding, or threading. Alternatively, the second portion 122 and the first portion 121 can be integrally formed to form a single structural component. Therefore, this application does not impose any specific limitations on this.

[0145] In some examples, the through hole 120a may also extend radially through the surface of the support base 120. For example, along the Z-axis, the through hole 120a extends through the upper surface of the support base 120. This allows the rotating base 200 to be installed by simply inserting the rotating shaft 240 from the upper side of the second portion 122 into the through hole 120a, further simplifying installation.

[0146] Also, please continue reading Figure 21 and Figure 22The support base 120 may further include a third portion 123, with the third portion 123 fixed to the surfaces of the two second portions 122 facing away from each other. The third portion 123 is configured to be fixedly connected to the upper shell 22 or the bottom shell 23 of the keyboard portion 20. For example, the third portion 123 may be formed into a flat plate structure parallel to the XY plane, thereby increasing the contact area between the third portion 123 and the mounting surface of the upper shell 22 or the bottom shell 23, thereby increasing the connection strength between the support base 120 and the keyboard portion 20 and improving the reliability of the overall structure.

[0147] The fixing base 130 can be fixed to the surfaces of the two second portions 122 of the support base 120 that are separated from each other, so that the fixing base 130 is disposed at the end of the rotating shaft 240, thereby facilitating installation. The fixing base 130 can also be staggered with the third portion 123 on the surface of the second portion 122 to ensure the rationality of the overall structure and avoid mutual interference.

[0148] For example, only one fixing seat 130 may be provided, that is, the damping force is generated by one fixing seat 130 and the corresponding rotating shaft 240, and in this case, the fixing seat 130 may be fixedly connected to any one of the two second parts 122. Alternatively, two fixing seats 130 may be provided (e.g., Figure 21 and Figure 22 As shown), that is, a fixing seat 130 is correspondingly provided for each of the two rotating shafts 240, and the two fixing seats 130 are fixedly connected to the two second parts 122 respectively, so that the force on both sides of the rotating seat 200 along the axial direction is balanced.

[0149] It should be noted that the shaft hole 110 opened on the above-mentioned fixing seat 130 and the connection structure between the shaft hole 110 and the rotating shaft 240 are the same as the structure provided in the above-mentioned embodiment. Therefore, the structure of the shaft hole 110 opened on the fixing seat 130 will not be repeatedly described.

[0150] On this basis, a limiting structure can be set between the extension part 230 of the above-mentioned rotating seat 200 and the second part 122 of the support seat 120. The limiting structure can limit the maximum rotation angle of the rotating seat 200, that is, it can limit the maximum rotation angle of the display part 10 to avoid the risk of damage caused by excessive rotation of the display part 10.

[0151] Specifically, the rotating base 200 can rotate relative to the supporting base 120 between a first position and a second position. When the rotating base 200 is in the first position, please continue to refer to Figure 21 and Figure 22 At least a portion of the arc-shaped portion 210 of the rotating base 200 is located between the two second portions 122 , that is, the electronic device 01 is in a folded state at this time.

[0152] See also Figure 23 and Figure 24 , Figure 23 This is a structural diagram of another rotating shaft mechanism 30 provided in an embodiment of the present application. Figure 24 for Figure 23 An exploded view of the hinge mechanism 30 is provided. When the rotating base 200 is in the second position, the arc-shaped portion 210 rotates outside the two second portions 122, i.e., the electronic device 01 is in the unfolded state, and the limiting structure prevents the rotating base 200 from rotating further in the direction from the first position to the second position, i.e., the display portion 10 cannot continue to rotate away from the keyboard portion 20.

[0153] For some examples, see Figure 23 and Figure 24 The limiting structure may include a limiting protrusion 124 and a limiting groove 231, one of which is disposed on the extension portion 230, and the other of which is disposed on the second portion 122. For example, the limiting protrusion 124 is disposed on a surface of the second portion 122 away from the fixing seat 130, and the limiting groove 231 is provided on a surface of the extension portion 230 facing the second portion 122.

[0154] When the rotating base 200 is in the first position, that is, the electronic device 01 is in the folded state, the limiting protrusion 124 and the limiting groove 231 are separated from each other; when the rotating base 200 is in the second position, that is, the electronic device 01 is in the unfolded state, the limiting protrusion 124 abuts against the limiting groove 231, thereby preventing the rotating base 200 from rotating further, that is, preventing the display part 10 from rotating further.

[0155] Furthermore, the aforementioned limiting structure may be provided only between one extension portion 230 and the corresponding second portion 122, and may not be provided between the other extension portion 230 and the corresponding second portion 122. Alternatively, the limiting structure may be provided between both extension portions 230 and the corresponding second portions 122 to ensure balanced force and improve the limiting effect.

[0156] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0157] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
