Description

Technical Field

[0001] This application relates to the field of terminal equipment technology, and in particular to a rotating shaft mechanism and an electronic device. Background Technology

[0002] Foldable electronic devices (such as laptops) are increasingly favored by users due to their portability.

[0003] The laptop computer includes a display section and a keyboard section, which are rotatably connected by a hinge mechanism, allowing the display section to rotate relative to the keyboard section to achieve folding.

[0004] However, the hinge mechanism of existing laptops has a complex overall structure, making disassembly and repair difficult. Summary of the Invention

[0005] This application provides a hinge mechanism and an electronic device to solve the problem that the hinge mechanism of existing laptops has a complex structure, which leads to greater difficulty in disassembly, assembly, and repair.

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

[0007] In a first aspect, a rotating shaft 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, and the rotating seat has an inner surface and an outer surface. The rotating seat is rotatably connected to the base, and the axis of rotation connecting 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 connected to the rotating seat, forming a wire-passing channel between the baffle and the rotating seat, the wire-passing channel extending around the rotation axis.

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

[0009] The hinge mechanism provided in the first aspect of this application allows the aforementioned cable routing channel to accommodate a flexible connector (e.g., an FPC board) between the first and second components, thereby enabling electrical connection between the display section and the keyboard section via the FPC board. The baffle effectively shields and protects the flexible connector.

[0010] Meanwhile, the baffle is located on one side of the outer surface of the rotating base, allowing it to be exposed as an exterior component when the electronic device is in the unfolded state, thus shielding the rotating base and flexible connectors. Since the baffle is an independent structural component, aesthetic processing of the baffle can enhance the overall appearance of the electronic device.

[0011] Furthermore, when repair or replacement of the flexible connector is required, only the baffle needs to be removed to expose the flexible connector, facilitating such repair or replacement. During disassembly, the entire rotating shaft mechanism does not need to be disassembled, thus reducing the difficulty of disassembly.

[0012] In one possible implementation of the first aspect of this application, a wire-passing groove is formed on the outer surface of the rotating seat, and the wire-passing groove forms a wire-passing channel between the rotating seat and the baffle. In this structure, the baffle is attached to the outer surface of the rotating seat, so that the baffle and the inner wall of the wire-passing groove can enclose the aforementioned wire-passing channel, which makes the structure simpler and the processing and installation more convenient.

[0013] In one possible implementation of the first aspect of this application, a receiving groove is formed on the outer surface of the rotating seat, a wire guide groove is formed on the bottom surface of the receiving groove, and a baffle is disposed within the receiving groove. This arrangement of the baffle within the receiving groove increases the contact area between the baffle and the rotating seat, thereby enhancing the connection strength between them and improving the overall structural reliability.

[0014] In one possible implementation of the first aspect of this application, the outer wall of the baffle is flush with the outer surface of the rotating seat. This structure prevents the baffle from protruding from the outer surface of the rotating seat, thus improving aesthetics.

[0015] In one possible implementation of the first aspect of this application, a baffle covers the outer surface of the rotating base. With 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 aesthetic feature, which improves the overall appearance.

[0016] In one possible implementation of the first aspect of this application, the rotating seat further has two opposing sidewalls, which are connected between the outer surface and the inner surface of the rotating seat; a baffle covers the two sidewalls of the rotating seat. In this structure, the exposed portion of the rotating seat is enclosed by the baffle, making the exposed portion of the rotating shaft mechanism an integrated unit, which further enhances the overall aesthetics.

[0017] In one possible implementation of the first aspect of this application, the baffle and the rotating seat are detachably connected. This helps to further reduce the difficulty of disassembling the baffle, that is, to reduce the difficulty of disassembling and installing the aforementioned flexible connector.

[0018] In one possible implementation of the first aspect of this application, one of the baffle and the rotating seat is provided with a snap-fit ​​hole, and the other of the baffle and the rotating seat is provided with a snap-fit ​​protrusion, which snaps into the snap-fit ​​hole. Exemplarily, the snap-fit ​​structure can be provided at both ends of the circumferential direction along the rotation axis of the rotating seat, and the snap-fit ​​structure is 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.

[0019] In this way, two sets of snap-fit ​​structures are provided between each side wall of the rotating seat and the baffle. That is, the rotating seat is provided with snap-fit ​​structures on both sides along the axial direction of the rotation axis, and the two ends along the circumferential direction of the rotation axis. This ensures that the force is balanced when the rotating seat and the baffle are snapped and fixed, which helps to improve the reliability of the connection between the two.

[0020] In one possible implementation of the first aspect of this application, the rotating seat includes an arc-shaped portion and a connecting portion. The axis of the arc-shaped portion is parallel to the axis of rotation. The connecting portion is disposed at the circumferential end of the arc-shaped portion and is used for fixed connection with the second component. The arc-shaped portion is rotatably connected to the base. The surface of the arc-shaped portion away from the axis is the outer surface.

[0021] In this way, the arc-shaped part is used to form a wire passage between itself and the baffle, and the connecting part can be fixedly connected to the structural components of the display part. For example, the connecting part can extend between the display screen and the top cover of the display part and be fixedly connected to the top cover.

[0022] In one possible implementation of the first aspect of this application, the rotating shaft mechanism further includes a pressure plate, with the connecting part fixedly connected to the pressure plate, and the pressure plate fixedly connected to the second component. This structure reduces the volume of the connecting part and increases the contact area between it and the second component through the pressure plate. On the one hand, this improves the overall connection strength; on the other hand, it reduces the installation difficulty of the rotating shaft mechanism.

[0023] In one possible implementation of the first aspect of this application, the pressure plate includes a first plate and a second plate. The first plate has second plates on both sides along the axial direction of the arcuate portion. The connecting portion is fixedly connected to the first plate, and the second plates are fixedly connected to the second component. That is, the second plates increase 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 this application, one of the base and the rotating seat has a shaft hole, and the other of the base and the rotating seat has a rotating shaft inserted into the shaft hole. With this structure, the rotating shaft mechanism is simpler, has fewer parts, which helps to reduce the overall size of the rotating shaft mechanism and contributes to the thinning and lightening of electronic devices.

[0025] In one possible implementation of the first aspect of this application, the rotating shaft and the shaft hole are interference-fitted. This allows the friction generated between the rotating base and the base during relative rotation to form a damping force during the rotation of the rotating shaft mechanism. This enables the display portion of the electronic device to remain at any position relative to the keyboard portion when the display portion rotates relative to the keyboard portion, adapting to different user habits and usage scenarios.

[0026] In one possible implementation of the first aspect of this application, the rotating seat includes an arc-shaped portion and an extension portion. The axis of the arc-shaped portion is parallel to the axis of the rotating shaft. Along the circumference of the arc-shaped portion, the first end of the arc-shaped portion is used for fixed connection with the second component. The extension portion is disposed 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] In this structure, the rotating shaft is fixed to the extension, which allows the rotating shaft to be coaxially arranged with the arc-shaped part. This enables the arc-shaped part to rotate around its own axis when it rotates, thereby reducing the diameter of the circular motion trajectory formed during the rotation of the arc-shaped part. This reduces the space occupied by the rotating shaft mechanism during rotation, which in turn reduces the space occupied in electronic devices and contributes to the thinning and lightening of electronic devices.

[0028] In one possible implementation of the first aspect of this application, two extensions are provided, distributed along the axial direction of the arc-shaped portion. Each extension is equipped with a rotating shaft, which is coaxially arranged, with the two extensions located between the two rotating shafts. Both rotating shafts are inserted into shaft holes on the base. In this structure, rotating shafts are provided on both sides of the rotating seat along the axial direction, which facilitates balanced force distribution and improves structural reliability.

[0029] In one possible implementation of the first aspect of this application, two bases are provided, distributed on both sides of the rotating seat along a direction parallel to the rotation axis. Shaft holes are formed on the bases, and the rotating shaft is fixed to the rotating seat, with both ends of the shaft extending into the shaft holes on the two bases respectively. In this structure, both bases are fixed to the first component, and the two rotating shafts can be correspondingly inserted into the shaft holes on the two bases, thereby facilitating overall force balance.

[0030] In one possible implementation of the first aspect of this application, the base includes a support and a fixed base. A shaft hole is formed in the fixed base, and a through hole is formed in the support. The fixed base is fixedly connected to the support. A rotating shaft is fixed to a rotating base, inserted into the through hole, and inserted into the shaft hole. In this structure, the support can be installed inside the first component first. Since there is no interference fit between the through hole and the rotating shaft, inserting the rotating shaft into the through hole achieves a rotatable connection between the rotating base and the support. Then, the shaft hole of the fixed base is fitted onto the end of the rotating shaft to provide damping force. This helps reduce the installation difficulty of the rotating shaft mechanism inside electronic equipment.

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

[0032] In one possible implementation of the first aspect of this application, the support base includes a first part and two second parts. The two second parts are distributed along a direction parallel to the rotation axis and are respectively fixed to both ends of the first part. Each of the two second parts has a through hole, and both ends of the rotating shaft are respectively inserted into the through holes of the two second parts. In this way, the space enclosed by the first and second parts of the support base can accommodate the part of the rotating base on which the rotating shaft is provided, thereby improving the integration of the rotating shaft mechanism composed of the base and the support base, that is, it is beneficial to further reduce the overall volume of the rotating shaft mechanism, thus contributing to the thinning and lightening of electronic devices.

[0033] In one possible implementation of the first aspect of this application, the support base further includes a third part, which is fixed to the opposing surfaces of the two second parts. The third part is used for fixed connection with the first component. In this way, the third part is provided on both sides of the two second parts symmetrically, so that when the base is fixed to the first component, the overall force is more balanced, thereby improving the connection reliability between the base and the first component.

[0034] In one possible implementation of the first aspect of this application, the rotating seat includes the aforementioned arc-shaped portion and the aforementioned extension portion. The axis of the arc-shaped portion is parallel to the rotation axis between the rotating seat and the base. Along the circumference of the arc-shaped portion, the first end of the arc-shaped portion is used for fixed connection with the second component. The extension portion is disposed at the second end of the arc-shaped portion and extends in a direction close to the axis of the arc-shaped portion. A limit structure is provided between the extension portion and the second portion.

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

[0036] For example, in the case of the aforementioned laptop computer, when the display portion rotates away from the keyboard portion, the limiting structure can prevent the display portion from rotating excessively, so as to avoid damage.

[0037] In one possible implementation of the first aspect of this application, the limiting structure includes a limiting protrusion and a limiting groove, one of which is disposed on the extension, and the other is disposed on the second part. When the rotating seat is in the first position, the limiting protrusion separates from the limiting groove; when the rotating seat is in the second position, the limiting protrusion abuts against the limiting groove. That is, by the mutual abutment between the limiting protrusion and the limiting groove, excessive rotation between the rotating seat and the base is prevented, thereby improving the reliability of the overall structure.

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

[0039] In one possible implementation of the first aspect of this application, the shaft hole radially penetrates the surface of the base or rotating seat to form an opening. The width of the opening is smaller than the diameter of the rotating shaft in a direction perpendicular to the axial direction of the shaft hole, and a portion of the rotating shaft is located at the opening. For example, along the thickness direction of the electronic device, the shaft 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, while ensuring the strength of the pivot without reducing its diameter, it is also beneficial to reduce the size of the pivot mechanism along the thickness direction of the electronic device, thus contributing to the thinning and lightening of the electronic device.

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

[0042] In one possible implementation of the first aspect of this application, the axis of the shaft hole and the axis of the rotating shaft do not coincide. This structure allows the rotating shaft and the shaft hole to be eccentrically positioned, reducing the risk of the rotating shaft coming out of the opening.

[0043] In one possible implementation of the first aspect of this application, the axis of the shaft hole and the axis of the rotating shaft are distributed along a direction perpendicular to the mounting surface of the base and the first part. An opening is provided on the upper surface of the rotating seat along the thickness direction of the electronic device, thereby further reducing the risk of the rotating shaft coming off.

[0044] Secondly, an electronic device is provided, comprising a keyboard portion, a display portion, and a hinge mechanism. The hinge mechanism is as described in any of the above technical solutions, with its base fixedly connected to the keyboard portion and its rotating seat fixedly connected to the display portion.

[0045] The electronic device provided in the second aspect of this application, by including the rotating shaft mechanism as described in any of the above technical solutions, is able to solve the same technical problem and achieve the same technical effect.

[0046] In one possible implementation of the second aspect of this 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 is stacked on top of the first region. With this structure, the maximum thickness of the electronic device can be the thickness of the second region, thereby facilitating the thinning and lightening of the electronic device.

[0047] In one possible implementation of the second aspect of this application, an interface module is provided within the keyboard portion. The interface module's connector is located on a side wall of the keyboard portion parallel to and close to the axis of the hinge mechanism. This way, the interface module does not affect the thickness of the first region, thus contributing to the thinner and lighter design of the electronic device.

[0048] Alternatively, the thickness of the keyboard section can gradually decrease along the width direction from the rear (the side closer to the hinge mechanism) to the front (the side farther from the hinge mechanism), which also contributes to the thinning and lightening of electronic devices.

Detailed Implementation

[0074] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0075] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0076] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0077] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed connection, a detachable connection, or an integral part; it may be a direct connection or an indirect connection through an intermediate medium.

[0078] This application provides an electronic device, which is a type of foldable terminal device. For example, the electronic device may be a laptop computer, a foldable mobile phone, or a tablet computer. In the following embodiments, a laptop computer will be used as an example for illustration.

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

[0080] For ease of description below, an XYZ coordinate system is established, defining the width direction of electronic device 01 as the X-axis, the length direction of electronic device 01 as the Y-axis, and the thickness direction of electronic device 01 as the Z-axis. It should be noted that this coordinate system applies when electronic device 01 is in a folded state; when electronic device 01 is in an open state, the keyboard portion 20 of electronic device 01 adapts to this coordinate system.

[0081] It is understood that the coordinate system of electronic device 01 can be flexibly set according to actual needs. This application only provides an example and should not be considered as constituting a special limitation on this application. Figure 1 and Figure 2 The electronic device 01 is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1 and Figure 2 Restrictions.

[0082] The aforementioned display portion 10 is used to display images, videos, etc. The display portion 10 may include a top cover 11 and a display screen 12. The display screen 12 is fixed to the top cover 11, for example, by adhesive, snap-fit, or other means. The display screen 12 is located on the side of the top cover 11 closest to the keyboard portion 20. The top cover 11 can be made of metal or plastic. Therefore, this application does not impose any special limitations on the material of the top cover 11.

[0083] Furthermore, the aforementioned display screen 12 can be a flexible display screen 12 or a rigid display screen 12. For example, the display screen 12 can 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 (MLED) display screen 12, a micro light-emitting diode (MLED) display screen 12, a micro organic light-emitting diode (MOLED) display screen 12, a quantum dot light-emitting diode (QLED) display screen 12, a liquid crystal display (LCD) display screen 12, and so on.

[0084] The keyboard section 20 described above is used for editing or other operations on the content displayed on the display screen 12. The keyboard section 20 may include a keyboard 21, an upper shell 22, and a lower shell 23. The keyboard 21 is fixed to the upper shell 22, and the upper shell 22 and the lower shell 23 are fixedly connected, for example, by means of adhesive bonding, snap-fitting, threaded connection, or welding. An accommodating space (not shown in the figure) is formed between the upper shell 22 and the lower shell 23. This accommodating space is used to house electronic components of the electronic device 01, such as the motherboard, CPU (Central Processing Unit), graphics card, memory, fan, and interface modules.

[0085] Furthermore, the keyboard 21 is electrically connected to the motherboard, and the display screen 12 is electrically connected to the motherboard through a flexible connector, such as an FPC board (Flexible Printed Circuit Board), so that the content displayed on the display screen 12 can be edited through the keyboard 21.

[0086] The aforementioned hinge mechanism 30 connects the display section 10 and the keyboard section 20, allowing them to rotate relative to each other, thus enabling the electronic device 01 to switch between an open state and a folded state. The rotation axis of the hinge mechanism 30 is parallel to the Y-axis. When the electronic device 01 is in the open state, the display section 10 rotates away from the keyboard section 20, forming an angle between the display section 10 and the keyboard section 20, separating the display screen 12 from the keyboard 21. In this state, the user can view the content displayed on the display screen 12 and perform editing and other operations using the keyboard 21.

[0087] When the electronic device 01 is folded, the display portion 10 and the keyboard portion 20 are interlocked, the display screen 12 and the keyboard 21 are positioned opposite each other, and both the display screen 12 and the keyboard 21 are located between the top cover 11 and the bottom cover 23, thereby effectively protecting the display screen 12 and the keyboard 21. In this state, the electronic device 01 can form an approximately rectangular plate structure, making it easy to carry.

[0088] To enhance the user experience, the aforementioned hinge mechanism 30 can also provide damping force so that the display part 10 can be kept in different positions during the opening process of the electronic device 01, thereby adapting to different user habits and different usage scenarios, which is conducive to improving the user experience.

[0089] Furthermore, with the trend towards thinner and lighter electronic devices, higher requirements are placed on the structure and placement of the aforementioned hinge mechanism 30. Please refer to [link / reference]. Figure 3 and Figure 4 , Figure 3 This is an exploded view of the electronic device 01 provided in the embodiments of this application. Figure 4 This is a partial structural diagram of the electronic device 01 provided in the embodiment of this application in a folded state.

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

[0091] Furthermore, when the electronic device 01 is in a folded state, the display portion 10 and the first region 20a of the keyboard portion 20 are stacked, meaning that 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 may be equal to the thickness D2 of the second region 20b.

[0092] In this way, when the electronic device 01 is in a folded state, its maximum thickness is the thickness of the second region 20b. Therefore, the display part 10 is stacked on the keyboard part 20, which 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 region 20b.

[0093] Furthermore, the aforementioned interface module can be located 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 connector is located on the rear side of the keyboard portion 20 (i.e., along the X-axis direction, on the surface of the second region 20b that is away from the first region 20a). Since the connector size of the interface module has a standard dimension and cannot be arbitrarily changed, placing 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 will not increase due to the interface module, thereby contributing to the thinner and lighter design of the 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 stepped structure is formed at the junction of the first region 20a and the second region 20b. Therefore, the aforementioned 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 continue reading Figure 3 and Figure 4 and in conjunction with reference Figure 5 , Figure 5 This is a partial cross-sectional view of the keyboard portion 20 provided in an embodiment of this application. The upper surface of the keyboard portion 20 (i.e., the surface on which the keyboard 21 is disposed) may include a first surface 20c and a second surface 20d. The first surface 20c is located in the first region 20a, and the second surface 20d is located in the second region 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 stepped structure.

[0096] Furthermore, an installation port 24 communicating with the aforementioned receiving space can be provided at the junction between the first surface 20c and the second surface 20d. Figure 3The pivot mechanism 30 shown can connect the keyboard part 20 and the display part 10 through the mounting port 24, thereby realizing the rotatable connection between the keyboard part 20 and the display part 10.

[0097] In other embodiments, the keyboard portion 20 may also be configured 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 furthest from the user when in use) to the front side (the side closest to the user when in use).

[0098] In this way, since the rear of the keyboard section 20 is relatively thick, the interface module can be located on the rear side, and the interface module's connector is located on the rear side of the keyboard section 20. Simultaneously, the interface module does not increase the front thickness of the keyboard section 20, thus contributing to the slimming and lightweight design of the electronic device 01. In this configuration, the hinge mechanism 30 can be located at the rear edge of the keyboard section 20, thereby enabling a rotatable connection between the keyboard section 20 and the display section 10.

[0099] Therefore, this application does not impose any special limitation on the specific location of the hinge mechanism 30. In the following embodiments, the keyboard portion 20 includes the first region 20a and the second region 20b, and the hinge mechanism 30 is located at the junction of the first region 20a and the second region 20b as an example for description.

[0100] Based on this, please refer to Figure 6 , Figure 6 This is a partial cross-sectional view of the electronic device 01 provided in an embodiment of this application. The display screen 12 of the display portion 10 (e.g., Figure 1 The keyboard portion 20 and the motherboard inside the keyboard portion 20 are electrically connected by 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 a part of the flexible connector is located outside the keyboard portion 20 and the display portion 10, that is, at least a part of the flexible connector needs to be exposed.

[0101] For aesthetic purposes and to effectively protect the flexible connector, in related technologies, the exposed portion of the flexible connector of electronic device 01 can be housed within the pivot mechanism 30. This pivot mechanism 30 provides both shielding and protection for the exposed portion of the flexible connector, improving the overall aesthetics of electronic device 01. However, in this electronic device 01, the pivot mechanism 30 has a complex structure, making disassembly difficult when the flexible connector needs maintenance, thus impacting the user experience.

[0102] To address the aforementioned problems, this application provides a rotating shaft mechanism 30, which can be applied to the aforementioned electronic device 01. Please refer to... 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 this application. Figure 8 This is a partial cross-sectional view of a rotating shaft mechanism 30 installed in an electronic device 01 according to an embodiment of this application. Figure 9 An exploded view of a rotating shaft mechanism 30 provided in an embodiment of this application. Figure 10 This is a cross-sectional view of a rotating shaft mechanism 30 provided in an embodiment of this application.

[0103] Specifically, the pivot 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 aforementioned accommodating 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 accommodating space through the aforementioned mounting port 24 and is rotatably connected to the base 100. The rotation axes of the two are parallel to the aforementioned Y-axis direction, thereby enabling a rotatable connection between the keyboard part 20 and the display part 10.

[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 (e.g. Figure 8 When the rotating base 200 rotates out of the receiving space from the mounting port 24 (as shown), a portion of the rotating base 200 faces the surface of the keyboard portion 20 (i.e., the surface of the keyboard portion 20). Figure 8 The concave surface is the inner surface 200b, and the surface of the rotating seat 200 away from the keyboard portion 20 is the outer surface 200a. The axis of rotation between the rotating seat 200 and the base 100 is located on one side of the inner surface 200b of the rotating seat 200.

[0105] In addition, please continue to refer to Figures 7-10 The rotating mechanism 30 also includes a baffle 300, which is disposed on one side of the outer surface 200a of the rotating seat 200 and connected to the rotating seat 200. A wire passage 400 is formed between the baffle 300 and the rotating seat 200. The wire passage 400 extends around the rotation axis between the rotating seat 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 portion 10 to the keyboard portion 20.

[0106] In this way, by placing the flexible connector within the cable passage, it can be shielded and protected. 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 exterior component.

[0107] On the one hand, simply removing the baffle 300 exposes the flexible connector, facilitating its repair or replacement. Furthermore, the entire rotating shaft mechanism 30 does not need to be disassembled during disassembly, reducing the difficulty of disassembly. On the other hand, since the baffle 300 is an external component and an independent structural part, it can be aesthetically pleasing through processing, thereby enhancing the overall appearance of the electronic device 01 and improving the user experience.

[0108] In some examples, the outer surface 200a of the aforementioned rotating seat 200 may have a wire-passing groove 201, which forms the aforementioned wire-passing channel 400 between the baffle 300 and the rotating seat 200. That is, a wire-passing channel 400 is formed between the baffle 300 and the inner wall of the wire-passing groove 201, thereby preventing the flexible connector located in the wire-passing groove 201 from being exposed.

[0109] In addition, please 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 this application. Figure 12 for Figure 11 The provided assembly drawing shows the rotating base 200 and the baffle 300. A receiving groove 202 can also be formed on the outer surface 200a of the rotating base 200. The aforementioned wire guide groove 201 is formed on the bottom surface of the receiving groove 202, and the baffle 300 can be disposed within the receiving groove 202. This arrangement of 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 them and enhancing the overall structural reliability.

[0110] For example, when the baffle 300 and the rotating seat 200 are fixed together by adhesive, increasing the contact area between the two will help improve the bonding strength, thereby improving the connection strength between the baffle 300 and the rotating seat 200.

[0111] Furthermore, the outer wall of the baffle 300 (i.e. the surface away from the wire groove 201) can be flush with the outer surface 200a of the rotating seat 200 to prevent the baffle 300 from protruding from the outer surface 200a of the rotating seat 200, which helps to improve the overall aesthetics.

[0112] Alternatively, please see Figure 13 , Figure 13This is an assembly diagram of another rotating base 200 and baffle 300 provided in an embodiment of this 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 part of the outer surface 200a of the rotating base 200; or, it can cover the entire area of ​​the outer surface 200a of the rotating base 200. That is, the outer surface 200a of the rotating base 200 and the wire groove 201 on the outer surface 200a are both covered by the baffle 300, so that the baffle 300 is entirely an appearance component, which helps to improve the overall aesthetics.

[0113] Furthermore, the rotating seat 200 also has two opposing sidewalls 200c, which are connected between the inner surface 200b and the outer surface 200a of the rotating seat 200.

[0114] In some possible examples, the baffle 300 may also cover the two side walls 200c of the rotating seat 200. In this way, the baffle 300 can cover the outer surface 200a and the two side walls 200c of the rotating seat 200, so that the exposed part of the rotating seat 200 is completely wrapped by the baffle 300. This can protect the rotating seat 200 while making the exposed part of the rotating shaft mechanism 30 integrated, hiding the gaps between the connected parts, thereby further improving the overall aesthetics.

[0115] In other possible examples, the baffle 300 can be fastened to the rotating seat 200, and the baffle 300 is connected to the two side walls 200c of the rotating seat 200. The baffle 300 and the outer surface 200a of the rotating seat 200 are spaced apart, thereby forming the aforementioned wire passage 400 between the baffle 300 and the rotating seat 200. With this structure, it is possible to avoid slotting on the outer surface 200a of the rotating seat 200, which helps to reduce the number of process steps and reduce the processing difficulty.

[0116] In some embodiments, the baffle 300 and the rotating seat 200 may be detachably connected to further reduce the difficulty of disassembling the baffle 300. For example, please refer to... Figure 11 , Figure 12 as well as Figure 13 The edge of the baffle 300 may have a snap-fit ​​hole 310, and the side wall 200c of the rotating seat 200 is provided with a snap-fit ​​protrusion 203. The edge of the baffle 300 is bent to face the side wall 200c of the rotating seat 200, and the snap-fit ​​protrusion 203 is engaged in the snap-fit ​​hole 310, thereby realizing the snap-fit ​​between the baffle 300 and the rotating seat 200. Alternatively, the baffle 300 and the rotating seat 200 may be connected by screws, that is, the baffle 300 and the rotating seat 200 are provided with threaded holes, thereby locking and fixing them.

[0117] In addition, the connection point between the baffle 300 and the rotating seat 200 can be set at both ends of the circumference along the aforementioned rotation axis, so as to hide the connection structure between the two (i.e., the snap-fit ​​protrusion 203 and the snap-fit ​​hole 310), thereby further improving the overall aesthetics.

[0118] In other possible embodiments, the baffle 300 and the rotating seat 200 can also be fixedly connected by means of bonding, welding, etc., which helps to improve the connection strength between the two. Therefore, this application does not make any special limitation in this regard.

[0119] Based on the above, please refer to Figure 14 and Figure 15 , Figure 14 Exploded views of the rotating seat 200, baffle 300, and pressure plate 500 provided in the embodiments of this application. Figure 15 for Figure 14 Assembly drawings of the rotating base 200, baffle 300, and pressure plate 500 are provided. To facilitate the installation of the rotating base 200, the rotating base 200 may include an arc-shaped portion 210 and a connecting portion 220. The axis of the arc-shaped portion 210 is parallel to the aforementioned rotation axis (i.e., the rotation axis through which the rotating base 200 and the base 100 are rotatably connected). The connecting portion 220 is disposed at the first circumferential end of the arc-shaped portion 210 and is used for fixed connection with the aforementioned display portion 10. The second end of the arc-shaped portion 210 is used for rotatable connection with the base 100.

[0120] Specifically, after the second end of the arc-shaped portion 210 is rotatably connected to the base 100, the first end of the arc-shaped portion 210 and the connecting portion 220 can be connected via the above-mentioned... Figure 8 The mounting port 24 shown is rotated out of the aforementioned receiving space. Then, the connecting part 220 is fixedly connected to the aforementioned display part 10. For example, the connecting part 220 and the upper cover 11 of the display part 10 can be fixed by welding, bonding or bolting.

[0121] In some embodiments, due to the above Figure 8 The mounting port 24 shown is located on the upper shell 22 of the keyboard section 20. That is, when the electronic device 01 is in the unfolded state, the mounting port 24 of the upper shell 22 will be exposed, and the user can directly see the mounting port 24. Therefore, the smaller the size of the mounting port 24, the better it is for the overall aesthetics.

[0122] Based on this, please continue reading Figure 14 and Figure 15The aforementioned rotating shaft mechanism 30 may further include a pressure plate 500. The connecting portion 220 of the aforementioned rotating seat 200 is fixedly connected to the pressure plate 500, and the pressure plate 500 is fixedly connected to the upper cover 11 of the display portion 10. Specifically, the pressure 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 along the axial direction of the arc-shaped portion 210. The connecting portion 220 is fixedly connected to the first plate 510, and the second plates 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. Simultaneously, the pressure plate 500 increases the contact area with the upper cover 11, thereby enhancing 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 allows for a corresponding reduction in the size of the mounting opening 24 on the upper shell 22. The size of the mounting opening 24 is only required to allow the rotating part and the connecting portion 220 to rotate normally and pass through it. Therefore, reducing the size of the mounting opening 24 further improves the aesthetics of the electronic device 01.

[0124] Furthermore, during installation, first connect the rotating base 200 to the base 100 by rotation, then rotate the connecting part 220 and the arc-shaped part 210 of the rotating base 200 outward through the mounting port 24. Then, fix the pressure plate 500 to the connecting part 220, and finally, fix the pressure plate 500 to the top cover 11.

[0125] In some examples, the first plate 510 of the pressure plate 500 and the connecting part 220, as well as the second plate 520 of the pressure plate 500 and the upper cover 11 of the display part 10, can be fixed by bolts. Furthermore, to ensure the strength of the fixed connection, multiple connection points can be provided between the first plate 510 and the connecting part 220, and between the second plate 520 and the upper cover 11. These multiple connection points are avoided to be on the same straight line, thereby increasing the area of ​​the locking force at the multiple connection points and improving the connection strength.

[0126] Furthermore, the aforementioned baffle 300 is disposed on one side of the outer surface 200a of the rotating seat 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 seat 200. Moreover, the snap-fit ​​structure between the baffle 300 and the rotating seat 200, namely the snap-fit ​​hole 310 and the snap-fit ​​protrusion 203, can be disposed between the baffle 300 and the side wall 200c of the connecting portion 220, thereby improving connection reliability while also helping to conceal the snap-fit ​​hole 310 and the snap-fit ​​protrusion 203, thus enhancing the overall aesthetics.

[0127] It is understandable that, since both ends of the rotating seat 200 and the baffle 300 are provided with a connection structure formed by snap-fit ​​holes 310 and snap-fit ​​protrusions 203, that is, the second end of the arc-shaped part 210 away from the connecting part 220 is also provided with this connection structure, so that a total of four sets of snap-fit ​​holes 310 and snap-fit ​​protrusions 203 are provided between the baffle 300 and the rotating seat 200, that is, four connection points are formed, which is conducive to the force balance of the overall connection structure.

[0128] Based on this, the above is a detailed description of the connection structure between the rotating base 200 and the display section 10. The following is a detailed description of the connection structure between the rotating base 200 and the base 100. Please refer to... Figure 16 and Figure 17 , Figure 16 This is a structural diagram of another rotating shaft mechanism 30 provided in an embodiment of this application. Figure 17 for Figure 16 Exploded view of the provided rotating shaft mechanism 30.

[0129] The rotating seat 200 and the base 100 are rotatably connected via a rotating shaft 240 and a shaft hole 110. Specifically, one of the base 100 and the rotating shaft 240 has a shaft hole 110, and the other of the base 100 and the rotating shaft 240 has a rotating shaft 240. The rotating shaft 240 is inserted into the shaft hole 110, thereby achieving a rotatable connection between the rotating seat 200 and the base 100.

[0130] Specifically, the aforementioned rotating base 200 may further include an extension 230, which is disposed at the second end of the arcuate portion 210, i.e., the end away from the connecting portion 220. Furthermore, the extension 230 extends from the second end of the arcuate portion 210 towards the axis of the arcuate portion 210. The aforementioned rotating shaft 240 may be fixed to the extension 230, and the shaft hole 110 may be formed in the base 100. For example, the axis of the rotating shaft 240 may coincide with the axis of the arcuate portion 210 (i.e., parallel to the Y-axis direction), meaning the arcuate portion 210 and the rotating shaft 240 are coaxially arranged.

[0131] To ensure a balanced force between the rotating seat 200 and the base 100 during rotational connection, two extensions 230 can be provided. These two extensions 230 are distributed along the axial direction of the arc-shaped portion 210, and each extension 230 is equipped with a rotating shaft 240. The two rotating shafts 240 are coaxially arranged, and the two extensions 230 are positioned between them. Both rotating shafts 240 are inserted into the shaft holes 110 on the base 100. In this way, the arc-shaped portion 210 has a connection structure for rotational connection with the base 100 on both sides along its own axial direction, allowing the rotating seat 200 to be evenly stressed on both sides along the axial direction, thus improving the overall structural reliability.

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

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

[0134] In some examples, the aforementioned pivot 240 and the pivot hole 110 can be interference-fitted. In this way, when the rotating seat 200 and the base 100 rotate relative to each other, the friction generated between them can form a damping force when the pivot mechanism 30 rotates, so that when the display part 10 of the electronic device 01 rotates relative to the keyboard part 20, the display part 10 can stay in any position relative to the keyboard part 20 to adapt to different users' usage habits and different usage scenarios.

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

[0136] For other examples, please refer to [link / reference]. Figure 16 and Figure 17 The aforementioned shaft hole 110 can radially penetrate the surface of the base 100 to form an opening 111. 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 portion 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 a central arc angle greater than 180° and less than 360°. This allows the rotating shaft 240 and the shaft hole 110 to achieve a rotatable connection while also reducing the weight of the base 100.

[0137] And, please see Figure 18 , Figure 18 for Figure 16The provided structural diagram shows the rotating shaft 240 of the rotating shaft mechanism 30 and the shaft hole 110 of the base 100. A portion of the rotating shaft 240 can extend out of the shaft hole 110 through the opening 111, meaning that 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. With this structure, it is beneficial to reduce the size of the base 100 along the Z-axis, so that without reducing the diameter of the rotating shaft 240, i.e., ensuring the strength of the rotating shaft 240, it is also beneficial to further reduce the thickness of the electronic device 01.

[0139] Furthermore, to ensure smoother relative rotation between the rotating shaft 240 and the shaft hole 110, a lubricating material can be added between the rotating shaft 240 and the shaft hole 110 provided in this embodiment. Please refer to... Figure 19 , Figure 19 This is a structural diagram of a rotating shaft 240 provided in an embodiment of this 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. The annular groove 241 can be used to store lubricating material so that during the relative rotation of the shaft 240 and the shaft hole 110, the lubricating material can cover the outer wall of the shaft 240 and the inner wall of the shaft hole 110, thereby making the relative rotation between the shaft hole 110 and the shaft 240 smoother and reducing wear, which is beneficial to improving the user experience.

[0140] In some 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 this application. The axis of the rotating shaft 240 and the axis of the shaft hole 110 may not coincide. 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, the rotating shaft 240 and the shaft hole 110 are not coaxially arranged, i.e., eccentrically arranged. Therefore, during the relative rotation between the two, there can be an interference amount, which helps to reduce the risk of the rotating shaft 240 dislodging in the direction of the opening 111 and improves the reliability of the overall structure.

[0142] In another embodiment, please refer to Figure 21 and Figure 22 , Figure 21 This is a structural diagram of another rotating shaft mechanism 30 provided in an embodiment of this application. Figure 22 for Figure 21An exploded view of the provided pivot mechanism 30. The base 100 of the pivot mechanism 30 may include a support 120 and a fixed base 130. The aforementioned shaft hole 110 is formed on the fixed base 130, and the support 120 has a through hole 120a. The fixed base 130 is fixedly connected to the support 120. The pivot 240 is inserted into the through hole 120a and also into the shaft hole 110. During installation, the support 120 is first fixed to the bottom shell 23 of the keyboard part 20. Then, the pivot 240 of the pivot 200 is inserted into the through hole 120a on the support 120. Since there is no interference fit between the through hole 120a and the pivot 240, the pivot 240 can rotate relative to the support 120 simply by inserting it into the through hole 120a. Then, the fixed base 130 is fitted onto the end of the pivot 240 and fixedly connected to the support 120. This makes installation simpler and more convenient, and helps to reduce the difficulty of installation.

[0143] The support base 120 may 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 (i.e., along the Y-axis direction) and are respectively fixed to both ends of the first part 121. Each of the two second parts 122 has a through hole 120a. The extension 230 of the rotating base 200 is disposed 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 continue reading Figure 21 and Figure 22 The first part 121 and the two second parts 122 are both flat plate structures, and the first part 121 and the second part 122 are arranged perpendicular to each other. For example, the first part 121 is parallel to the YZ plane, and the second part 122 is parallel to the XZ plane. The first part 121 and the second part 122 can be fixed by means of bonding, snap-fitting, welding, or threaded connection, or the second part 122 and the first part 121 can also be integrally formed to form a structural component. Therefore, this application does not impose any special limitations in this regard.

[0145] In some examples, the aforementioned through hole 120a may also penetrate the surface of the support base 120 radially. For example, along the Z-axis direction, the through hole 120a penetrates the upper surface of the support base 120. In this way, during the installation of the rotating base 200, it is only necessary to insert the rotating shaft 240 into the through hole 120a from the upper side of the second part 122 to achieve the installation of the rotating base 200 and the support base 120, which helps to further reduce the installation difficulty.

[0146] In addition, please continue to refer to Figure 21 and Figure 22The aforementioned support base 120 may further include a third portion 123, on which the third portion 123 is fixedly attached to the opposing surfaces of the two second portions 122. The third portion 123 is used for fixed connection with 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, thus improving the connection strength between the support base 120 and the keyboard portion 20, and enhancing the overall structural reliability.

[0147] The aforementioned fixing seat 130 can be fixed to the opposing surfaces of the two second parts 122 of the support seat 120, so that the fixing seat 130 is positioned at the end of the rotating shaft 240, thereby facilitating installation. Furthermore, the fixing seat 130 can be offset from the aforementioned third part 123 on the surface of the second part 122 to ensure the rationality of the overall structure and avoid mutual conflict.

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

[0149] It should be noted that the shaft hole 110 opened on the fixed 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 embodiment. Therefore, the structure of the shaft hole 110 opened on the fixed seat 130 will not be described again.

[0150] Based on this, a limiting structure can be provided between the extension 230 of the rotating seat 200 and the second part 122 of the support seat 120. This 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, so as to avoid the risk of damage caused by excessive rotation of the display part 10.

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

[0152] Please see Figure 23 and Figure 24 , Figure 23 This is a structural diagram of another rotating shaft mechanism 30 provided in an embodiment of this application. Figure 24 for Figure 23 An exploded view of the provided pivot mechanism 30. When the pivot 200 is in the second position, the arc-shaped portion 210 rotates beyond the two second portions 122, that is, the electronic device 01 is in the unfolded state, and the limiting structure can prevent the pivot 200 from continuing to rotate in the direction of rotation from the first position to the second position, that is, the display portion 10 cannot continue to rotate away from the keyboard portion 20.

[0153] In some examples, please refer to [link / reference]. Figure 23 and Figure 24 The limiting structure may include a limiting protrusion 124 and a limiting groove 231. One of the limiting protrusion 124 and the limiting groove 231 is disposed on the extension 230, and the other of the limiting protrusion 124 and the limiting groove 231 is disposed on the second portion 122. For example, the limiting protrusion 124 is disposed on the surface of the second portion 122 away from the fixing base 130, and the limiting groove 231 is formed on the surface of the extension 230 facing the second portion 122.

[0154] When the rotating base 200 is in the first position, i.e. the electronic device 01 is in a 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, i.e. the electronic device 01 is in an unfolded state, the limiting protrusion 124 abuts against the limiting groove 231, thereby preventing the rotating base 200 from rotating further, i.e. preventing the display part 10 from rotating further.

[0155] Furthermore, the aforementioned limiting structure can be provided only between one extension 230 and a corresponding second part 122, while the limiting structure between the other extension 230 and the corresponding second part 122 may not be provided. Alternatively, the limiting structure can be provided between both extensions 230 and the two corresponding second parts 122 to ensure balanced force distribution and improve the limiting effect.

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