Description

Technical Field

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

[0002] Foldable screen phones, tablets, and other portable electronic devices are relatively large and inconvenient to hold for extended periods, often requiring placement on a table. To stably support these devices, a stand is typically included. Stands can be divided into external stands and built-in stands. External stands are attached to the electronic device from the outside and come in various forms, such as metal stands, plastic stands, foldable stands, or even foldable cases that function as stands. The disadvantage of external stands is their inconvenience in carrying; they require assembly and disassembly, resulting in poor usability. Prolonged use of external devices like cases can make electronic devices bulky and heavy, negatively impacting the user experience. To improve portability, enhance user convenience, and improve the overall experience, some manufacturers integrate stands directly into the device's casing, creating built-in stands.

[0003] Electronic devices typically have built-in stands that connect to the device body via a hinge mechanism, allowing them to rotate relative to the device and switch between a retracted and an open state. When retracted, the stand fits snugly against the device, making it easy to hold and carry. When open, it opens at a certain angle relative to the device, supporting it on a table. The hinge mechanism includes a damping structure that generates damping force, allowing the stand to hover at a specific angle during rotation. The magnitude of this damping force directly determines the stability of the device on the table. However, in existing electronic devices with built-in stands, the damping force of the damping structure is related to its length, usually requiring a relatively long damping structure to achieve stable support. The width of the stand corresponds to the length of the damping structure; a longer damping structure results in a wider stand, leading to a larger overall size.

[0004] For example, some rotating mechanisms include a shaft and a sleeve. The shaft is fitted inside the sleeve, and the two rotate relative to each other. Connecting one part of the electronic device body and the bracket to the sleeve and the other to the shaft allows the bracket to rotate relative to the electronic device body about an axis, the direction of which is the same as the axis of the shaft. The relative rotation of the shaft and sleeve generates damping force through friction; the larger the contact area, the greater the damping force. To obtain sufficient damping force, the length of the shaft and sleeve can be increased along the axial direction. The width of the bracket (its dimension along the axial direction) is directly proportional to the length of the shaft and sleeve; increasing the length of the shaft and sleeve requires increasing the width of the bracket. Alternatively, multiple pairs of mating shafts and sleeves can be arranged along the axial direction, each pair providing damping force. In this case, the bracket needs to be connected to each pair of shafts and sleeves; the more shafts and sleeves there are, the wider the bracket becomes. Therefore, in either case, the width of the bracket will increase, resulting in a larger bracket size. The bracket occupies a larger area on the electronic device's casing, which in turn causes problems such as large differences in the appearance of the electronic device, low structural strength of the casing, and is not conducive to the design of thinner and lighter electronic devices.

[0005] It is evident that the hinge mechanism in existing electronic devices with built-in brackets cannot provide a large damping force when the bracket width is small, making it difficult to balance the stability of the bracket support with miniaturized design. Summary of the Invention

[0006] The rotating shaft mechanism and electronic device provided in this application embodiment solve the problem that the rotating shaft mechanism in the prior art electronic device with built-in bracket cannot provide a large damping force when the bracket width is small, and it is difficult to balance the stability of the bracket support and the miniaturization design.

[0007] This application provides a rotating shaft mechanism for connecting a first component and a second component. The first component is rotatably connected to the second component around a first axis. The rotating shaft mechanism includes a first damping structure, a second damping structure, and a connecting member. The first damping structure is installed on the first component. The first damping structure and the second damping structure are spaced apart in a first direction and connected by the connecting member.

[0008] When the first damping structure rotates relative to the second component around the first axis under the drive of the first component, it drives the second damping structure to rotate relative to the second component around the second axis through the connecting piece. Both the first axis and the second axis extend along the second direction, which is perpendicular to the first direction.

[0009] The rotating shaft mechanism provided in this application embodiment can be applied to electronic devices. The first component can be a bracket, and the second component can be the electronic device body. The rotating shaft mechanism can rotatably connect the electronic device body and the bracket, and the bracket can rotate relative to the electronic device body around a first axis. The rotating shaft mechanism includes two damping structures linked by a connecting member. When the bracket and the electronic device body rotate relative to each other, both damping structures provide damping force. The damping forces of each damping structure are superimposed and can be used to support the electronic device body. The first and second damping structures are arranged along a first direction, while the bracket rotates relative to the electronic device body around the first axis. The first axis extends along a second direction, and the first and second directions are perpendicular to each other. This can be understood as the arrangement direction of the two damping structures being perpendicular to the axis of rotation of the bracket.

[0010] In this structure, the bracket is mounted only on the first damping structure, and the width of the bracket (its dimension in the second direction) is only related to the dimension of the first damping structure in the second direction. However, the supporting force of the bracket on the electronic device body is the sum of the damping forces of the first and second damping structures. When the damping force of the first damping structure is insufficient, the second damping structure can compensate. Therefore, the size of the first damping structure can be reduced in the second direction, and the width of the bracket can be reduced accordingly. At the same time, the second damping structure can be designed to be larger to provide sufficient damping force, ensuring the stability of the bracket when supporting the electronic device body.

[0011] As can be seen, the pivot mechanism provided in this application embodiment can provide a large damping force when the width of the electronic device bracket is small, and can take into account both the stability of the bracket support and the miniaturization design.

[0012] In some embodiments, the first damping structure includes a first rotating shaft and a first sleeve, the first rotating shaft being sleeved inside the first sleeve and rotatable relative to the first sleeve about a third axis; the second damping structure includes a second rotating shaft and a second sleeve, the second rotating shaft being sleeved inside the second sleeve and rotatable relative to the second sleeve about a fourth axis.

[0013] The first rotating shaft is mounted on the first component, and the first sleeve is mounted on the first component via the first rotating shaft; both the first sleeve and the second sleeve are connected to the connector and fixed relative to the connector, so as to connect the first damping structure and the second damping structure via the connector.

[0014] The third and fourth axes both extend along the second direction, and each of the first, second, third, and fourth axes is spaced apart from the others; the distance between the first and second axes is equal to the distance between the third and fourth axes, and the distance between the first and third axes is equal to the distance between the second and fourth axes.

[0015] Using the above scheme, in a plane perpendicular to the second direction, the first axis, the second axis, the third axis, and the fourth axis form a parallelogram structure, that is, the second component, the first damping structure, the second damping structure, and the connecting member form a four-bar structure.

[0016] In some embodiments, a first limiting portion is provided inside the first sleeve, and a portion of the outer surface of the first rotating shaft along its circumference is formed as a plane. The first limiting portion is an elastic structure, and when the first rotating shaft rotates relative to the first sleeve to a first position, the first limiting portion and the first rotating shaft are engaged through a plane. A second limiting portion is provided inside the second sleeve, and a portion of the outer surface of the second rotating shaft along its circumference is formed as a plane. The second limiting portion is an elastic structure, and when the second rotating shaft rotates relative to the second sleeve to a second position, the second limiting portion and the second rotating shaft are engaged through a plane.

[0017] Using the above solution, the rotation angle of each shaft can be limited by the limiting part, so that the damping force of each damping structure changes with the opening angle of the bracket, providing the user with a different feel and reminding the user of the optimal angle for using the bracket.

[0018] In some embodiments, the connector is configured as a connecting rod, with a first sleeve and a second sleeve formed at both ends of the connecting rod, respectively. That is, both the first sleeve and the second sleeve are integrally formed with the connector, resulting in a simple structure and ease of manufacturing.

[0019] In some embodiments, the rotating shaft mechanism further includes:

[0020] The first fixing member is fixed to the first component, and the first rotating shaft of the first damping structure is mounted on the first fixing member. The first damping structure can be mounted on the first component through the first fixing member.

[0021] The second fixing member is fixed to the second component, and the second rotating shaft of the second damping structure is mounted on the second fixing member. The second damping structure can be mounted on the second component through the second fixing member.

[0022] The first fixing member can rotate relative to the second fixing member about the first axis, so that the first component can rotate relative to the second component about the first axis.

[0023] Using the above solution, the second fixing member is fixed to the electronic device body, and the bracket is fixed to the first fixing member, and is rotatably connected to the first fixing member and the second fixing member, and further rotatably connected to the electronic device body. When the user rotates the bracket, the bracket drives the first fixing member to rotate relative to the second fixing member. Since the second fixing member is fixed relative to the electronic device body, the first fixing member also rotates relative to the electronic device body, and the bracket rotates relative to the electronic device body.

[0024] In some embodiments, the first rotating shaft of the first damping structure is fixed to the first fixing member. With this structure, there is no relative rotation between the first rotating shaft and the first fixing member, which can better transmit the damping force of the first damping structure to the bracket.

[0025] In some embodiments, the first fixing member is slidably connected to the second fixing member, such that the first fixing member can rotate relative to the second fixing member about a first axis, and the first damping structure can rotate relative to the second fixing member under the influence of the first fixing member. The second damping structure is slidably connected to the second fixing member, such that the second damping structure can rotate relative to the second fixing member about a second axis.

[0026] In some embodiments, the second fixing member includes a base extending along a second direction and two extension arms respectively connected to both ends of the base in the second direction. Each of the two extension arms extends along a first direction and protrudes from the base in the same direction, such that the two extension arms and the base form an installation space. The first damping structure, the second damping structure, the connector, and the first fixing member are all installed within the installation space. In the first direction, the second damping structure is located on the side of the first damping structure closer to the base, and the first fixing member is located on the side of the first damping structure away from the base.

[0027] The first fixing member includes a base, a mounting part and two rotating arms. The base is fixedly connected to the first component, the mounting part is connected to the base and protrudes from the base in a first direction toward the side where the first damping structure is located. The first rotating shaft of the first damping structure is mounted on the mounting part.

[0028] Two rotating arms are respectively connected to both ends of the base in the second direction, and each of the two rotating arms corresponds one-to-one with the two extension arms of the second fixing member. Each of the two rotating arms is slidably connected to the corresponding extension arm through a first sliding structure, so that the first fixing member can rotate relative to the second fixing member about the first axis.

[0029] The first sliding structure includes a sliding arc-shaped groove and an arc-shaped slider, one of which is disposed on the rotating arm of the first fixing member and the other is disposed on the extension arm of the second fixing member.

[0030] In some possible embodiments, the arc-shaped groove of the first sliding structure is disposed on the rotating arm of the first fixing member, and the arc-shaped slider is disposed on the extension arm of the second fixing member.

[0031] In some embodiments, the mounting portion includes two bosses spaced apart in a second direction, a first damping structure located between the two bosses, and each of the two bosses having a through hole. The two ends of a first rotating shaft in the first damping structure protrude from the first sleeve and pass through the through holes of the two bosses, respectively. With this structure, the first fixing member can drive the first rotating shaft to move, so that the first damping structure can rotate relative to the second component.

[0032] In some possible embodiments, the two ends of the first rotating shaft are fixedly connected to two bosses, so that the first rotating shaft is fixed to the first fixing member.

[0033] In some embodiments, the first fastener further includes a protrusion connected to the base, the protrusion protruding from the base in a first direction toward the side opposite to the first damping structure and embedded in the first component.

[0034] By adopting the above solution, the connection strength between the mounting component and the first fixing component can be improved.

[0035] In some embodiments, the second damping structure further includes two bushings spaced apart along the second direction, the two bushings being respectively sleeved on both ends of the second rotating shaft; the two bushings correspond one-to-one with the two extension arms of the second fixing member, and each bushing is slidably connected to the corresponding extension arm through a second sliding structure, so that the second damping structure can rotate relative to the second fixing member about the second axis.

[0036] The second sliding structure includes an arc-shaped slider and an arc-shaped groove that are slidably connected to each other. One of the arc-shaped slider and the arc-shaped groove of the second sliding structure is disposed on the bushing, and the other is disposed on the extension arm of the second fixing member.

[0037] In some possible embodiments, the arc-shaped slider of the second sliding structure is disposed on the bushing, and the arc-shaped groove is disposed on the extension arm of the second fixing member.

[0038] In some embodiments, the second fixing member has two fixing portions, each of the two fixing portions including a first portion extending along a second direction and a second portion extending along a first direction, the first portion and the second portion being connected, the first portions of the two fixing portions being connected and fixedly connected to form a base of the second fixing member, and the second portions of the two fixing portions respectively forming two extension arms of the second fixing member.

[0039] Using the above scheme, the second fixing component adopts a split structure, which is divided into two fixing parts. Each fixing part includes an extension arm and a part of the seat, which facilitates the assembly of the rotating shaft mechanism.

[0040] This application also provides an electronic device, including an electronic device body and a bracket, and further including the hinge mechanism provided in any of the above embodiments. One of the electronic device body and the bracket is configured as a first component, and the other is configured as a second component, so as to rotatably connect the electronic device body and the bracket through the hinge mechanism. The electronic device utilizes the hinge mechanism provided in this application, resulting in a smaller bracket width, a smaller area occupied by the bracket on the electronic device's housing, smaller appearance variations in the electronic device, and higher structural strength, which is beneficial for the thinner and lighter design of the electronic device.

[0041] In some embodiments, the bracket is configured as a first component, and the electronic device body is configured as a second component. The electronic device body includes a display screen, a mid-frame, and a rear cover. The mid-frame includes a base plate and an outer frame. The display screen and the rear cover are respectively mounted at both ends of the outer frame in a third direction. The base plate is located between the display screen and the rear cover. The third direction is perpendicular to both the first and second directions.

[0042] The back cover of the electronic device body has a cutout, and the pivot mechanism and bracket are arranged on the bottom plate of the middle frame along the first direction. In the third direction, the bracket and pivot mechanism are correspondingly arranged in the cutout of the back cover.

[0043] The bracket includes a bracket body and a mounting component. The bracket body is a plate-like structure. The mounting component is connected to the bracket body and is located on the side of the bracket body facing the display screen in a third-dimensional direction. A pivot mechanism is mounted on the mounting component, allowing the bracket to rotate relative to the electronic device body about a first axis to switch between a retracted state and an open state. When the bracket is in the retracted state, the entire bracket body is embedded in the cutout portion of the back cover. When the bracket is in the open state, at least a portion of the bracket body detaches from the cutout portion and protrudes from the outer surface of the electronic device body.

[0044] With the above solution, when the bracket is in the retracted state, the bracket body can be embedded in the electronic device body without protruding from the electronic device body. The bracket will not increase the local thickness of the electronic device, making the electronic device lighter and thinner.

[0045] In some embodiments, the electronic device body further includes a cover plate disposed in the hollow portion of the rear cover. The cover plate is disposed along a first direction on the side of the bracket facing the rotating shaft mechanism and is connected to the bracket body, so that the cover plate and the bracket constitute a bracket structure. When the bracket is in a retracted state, the projection of the bracket structure along a third direction on the display screen coincides with the projection of the hollow portion along a third direction on the display screen.

[0046] The base plate of the mid-frame features a stepped structure. This stepped structure connects to the base plate and is located on the side of the base plate away from the display screen in the third direction. The stepped structure includes a top surface and a side surface that are perpendicular to each other. The side surface extends along the third direction, and the top surface connects to the end of the side surface that is away from the display screen in the third direction. When the bracket is in the retracted state, the top surface faces the bracket body. When the bracket is in the open state, an opening is formed between the bracket body and the top surface of the stepped structure.

[0047] Using the above solution, the stepped structure has a certain thickness. When the bracket body is rotated open, the top surface of the stepped structure can cover the opening between the bracket body and the electronic device body, allowing the user to see the top surface of the stepped structure instead of other electronic components in the electronic device. This enhances the aesthetics of the electronic device while protecting its electronic components.

[0048] In some embodiments, the first axis is located on the surface of the bracket structure that is third-direction upward away from the display screen and at the seam between the cover plate and the bracket body.

[0049] With the above solution, during the rotation of the bracket relative to the electronic device body, the upper surface of the bracket body and the upper surface of the cover plate are always in contact through the gap, resulting in a simple and beautiful appearance and smooth surface transition of the electronic device.

[0050] In some embodiments, the mounting component of the bracket is configured as an arc-shaped structure, and a receiving groove is provided inside the mounting component. A portion of the structure of the rotating shaft mechanism is located inside the receiving groove. When the bracket is in the retracted state, the entire mounting component is located on the side of the stepped structure facing the cover plate in the first direction. When the bracket is in the open state, at least a portion of the structure of the mounting component is located on the side of the stepped structure away from the cover plate in the first direction.

[0051] With the above solution, the arc-shaped mounting component is located in the gap between the stepped structure and the rotating shaft mechanism. When the bracket rotates, the arc-shaped structure also rotates within the gap. When the bracket body opens at a certain angle relative to the electronic device body, the arc-shaped structure is also exposed along with the bracket body, shielding the gap between the stepped structure and the rotating shaft mechanism, as well as the gap between the bracket body and the rotating shaft mechanism, thus providing all-round shielding for the rotating shaft mechanism.

[0052] In some possible embodiments, the receiving groove of the mounting component includes a first receiving groove and two second receiving grooves, each of the first receiving groove and the two second receiving grooves being spaced apart along a second direction, and the first receiving groove being located between the two second receiving grooves.

[0053] When the rotating shaft mechanism includes a first fixing member, and the first fixing member includes two rotating arms and a protrusion, at least a portion of the structure of the protrusion is located in the first receiving groove, and the two rotating arms correspond one-to-one with the two second receiving grooves, with at least a portion of the structure of each rotating arm located in the corresponding second receiving groove.

[0054] By adopting the above solution, the reliability of the connection between the bracket and the rotating shaft mechanism is improved by increasing the connection area between the two. Attached Figure Description

Approximate perpendicularity due to processing and assembly errors (e.g., the included angle between two structural features is 89.9°) is also within the scope of mutual perpendicularity in this application. Similarly, the mutual parallelism in this application is not absolute parallelism. Approximate parallelism due to processing and assembly errors (e.g., the included angle between two structural features is 0.1°) is also within the scope of mutual parallelism in this application. The axial symmetry in this application is not absolute axial symmetry. Approximate axial symmetry due to processing and assembly errors (e.g., a partial structure offset by a certain distance or angle relative to the axis of symmetry) is also within the scope of axial symmetry in this application. The central symmetry in this application is not absolute central symmetry. Approximate central symmetry due to processing and assembly errors (e.g., a partial structure offset by a certain distance or angle relative to the axis of symmetry) is also within the scope of central symmetry in this application. This application does not impose specific limitations in these respects.

[0132] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0133] Foldable screen phones, tablets, and other portable electronic devices are relatively large and inconvenient to hold for extended periods, often requiring placement on a table. To stably support these devices, a stand is typically included. Stands can be divided into external stands and built-in stands. External stands are attached to the electronic device from the outside and come in various forms, such as metal stands, plastic stands, foldable stands, or even foldable cases that function as stands. The disadvantage of external stands is their inconvenience in carrying; they require assembly and disassembly, resulting in poor usability. Prolonged use of external devices like cases can make electronic devices bulky and heavy, negatively impacting the user experience. To improve portability, enhance user convenience, and improve the overall experience, some manufacturers integrate stands directly into the device's casing, creating built-in stands.

[0134] Electronic devices typically have built-in stands that connect to the device body via a hinge mechanism, allowing them to rotate relative to the device and switch between a retracted and open state. When retracted, the stand fits snugly against the device, making it easy to hold and carry. When open, it opens at a certain angle relative to the device, supporting it on a table. The hinge mechanism includes a damping structure that generates damping force, allowing the stand to hover at a specific angle during rotation. The magnitude of this damping force directly determines the stability of the device on the table. However, in existing electronic devices with built-in stands, the damping force of the damping structure is related to its length, usually requiring a relatively long damping structure to achieve stable support. The width of the stand corresponds to the length of the damping structure; a longer damping structure results in a wider stand, leading to a larger overall size. The following section explains this issue using the structures of several electronic devices with built-in stands and their hinge mechanisms.

[0135] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic device.

[0136] like Figure 1 As shown, the electronic device 100' includes an electronic device body 1' and a bracket 2'. The bracket 2' is rotatably connected to the electronic device body 1' via a rotating shaft mechanism 3', and can rotate relative to the electronic device 100'. Specifically, the rotating shaft mechanism 3' includes a damping structure 31', which can be composed of a rotating shaft 311' and a sleeve 312'. The rotating shaft 311' is fitted inside the sleeve 312', and the two can rotate relative to each other. By connecting one of the electronic device body 1' and the bracket 2' to the sleeve 312' and the other to the rotating shaft 311', the bracket 2' can rotate relative to the electronic device body 1' around the first axis Q'. Figure 1 In the illustrated scenario, the bracket 2' is connected and fixed to the rotating shaft 311' via the connector 4', and the sleeve 312' is fixedly connected to the electronic device body 1'. The axial direction Y' (the direction where the first axis Q' is located) is the same as the axis of the rotating shaft 311', or it can be understood that the axis of the rotating shaft 311' is the first axis Q'.

[0137] When the rotating shaft 311' and sleeve 312' rotate relative to each other, they rub against each other, generating a damping force. This damping force can be used as the force for the bracket 2' to support the electronic device body 1'. The larger the contact area between the rotating shaft 311' and sleeve 312', the greater the damping force, and the more stably the bracket 2' supports the electronic device 100'. However, the rotating shaft 311' rotates relative to the sleeve 312' under the drive of the bracket 2'. To improve the stability of the rotation of the rotating shaft 311' and prevent the rotating shaft 311' from jamming, it is necessary to ensure that the force on the rotating shaft 311' is uniform. Generally, both ends of the rotating shaft 311' need to be connected to the bracket. For example, Figure 1 Both ends of the rotating shaft 311' are fixedly connected to both ends of the bracket 2' via a connector 4'. At this time, the width d' of the bracket 2' (the dimension of the bracket 2' in the axial direction Y') is directly proportional to the length of the rotating shaft 311' and the sleeve 312'; as the length of the rotating shaft 311' and the sleeve 312' increases, the width d' of the bracket 2' also needs to increase. To stably support the electronic device body 1' and obtain sufficient damping force, the length of the rotating shaft 311' and the sleeve 312' can be increased along the axial direction Y', increasing the contact area between the rotating shaft 311' and the sleeve 312', thus making the width d' of the bracket 2' longer.

[0138] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of another electronic device.

[0139] like Figure 2 As shown, the electronic device 100" includes an electronic device body 1" and a bracket 2". The bracket 2" is rotatably connected to the electronic device body 1" via a rotating shaft mechanism 3", and can rotate relative to the electronic device 100". Figure 1 The electronic device 100' shown differs in that its rotating shaft mechanism 3" includes multiple damping structures 31 (four shown in the figure) arranged along the axial direction Y". Each damping structure 31" includes a pair of cooperating rotating shafts 311" and sleeves 312". The bracket 2" can be connected to the rotating shafts 311" of each damping structure 31" via connectors 4". When the bracket 2" rotates, it drives each rotating shaft 311" to rotate relative to the corresponding sleeve 312". The frictional forces generated by the friction between the rotating shafts 311" and sleeves 312 in each damping structure 31" are superimposed to form the damping force of the rotating shaft mechanism 3", which is used to support the electronic device body 1". With this structure, multiple damping structures 31" are arranged along the axial direction Y (the direction where the first axis Q is located). The bracket 2" needs to be connected to the rotating shafts 311" in each damping structure 31". The more damping structures 31" there are, the larger the width d" of the bracket 2" will be. To ensure stable support for the electronic device body 1” with sufficient damping force, it is necessary to increase the number of damping structures 31”, and the width d” of the bracket 2” is also larger.

[0140] In summary, the hinge mechanism in electronic devices with built-in brackets cannot provide a large damping force when the bracket width is small, making it difficult to balance the stability of the bracket support with miniaturized design.

[0141] Those skilled in the art will understand that brackets are typically mounted on the housing of electronic devices. If the bracket is wide, its overall size is large, occupying a significant area on the housing and resulting in a large visual difference in the device's appearance. Since the bracket and the housing are separable structures, the space on the housing to accommodate the bracket usually requires a groove, reducing the housing's thickness and structural strength. Furthermore, to ensure the flatness of the electronic device's appearance, the bracket is generally an embedded design, completely embedded within the device body when stored. Given a fixed thickness, the electronic components inside the device corresponding to the bracket's position need to be spaced out. A large bracket size is detrimental to the spatial arrangement of electronic components, causing problems such as the inability to install some components. To avoid these problems, the thickness of the electronic device must be increased to increase the space for the electronic components. Therefore, a large bracket size is also detrimental to the design of thinner and lighter electronic devices.

[0142] To address the aforementioned issues, this application provides a pivot mechanism with damping structures arranged perpendicular to the axis, which can provide a large damping force even when the width of the electronic device's bracket is small, thus balancing the stability of the bracket support with miniaturized design.

[0143] This application also provides an electronic device that utilizes the pivot mechanism provided in this application. The bracket is narrow, occupies a small area on the housing of the electronic device, has small appearance differences, and high structural strength, which is beneficial for the thin and light design of the electronic device.

[0144] The electronic device provided in this application may be, but is not limited to, a mobile phone, tablet computer, monitor, personal digital device, smart wearable device, etc. The mobile phone may be a unibody phone or a foldable screen phone. The following description uses a foldable screen phone as an example to illustrate the structure of the electronic device. It should be noted that the following description of the electronic device's structure is merely illustrative and does not limit the electronic device provided in this application. In practice, the electronic device may include more or fewer components as shown in the following examples and figures.

[0145] Please see Figures 3a-6 , Figures 3a-3b This is a three-dimensional structural diagram of the electronic device from different perspectives according to an embodiment of this application, wherein the electronic device body is in an unfolded state; Figure 4 This is a three-dimensional structural diagram of an electronic device according to an embodiment of this application, wherein the electronic device body is in a folded state; Figure 5This is a rear view of an electronic device according to an embodiment of this application, wherein the electronic device body is in an unfolded state; Figure 6 This is a rear view of the electronic device with the cover removed, according to an embodiment of this application.

[0146] like Figures 3a-6 As shown, the electronic device 200 includes an electronic device body 7 and a bracket 81, with the bracket 81 supporting the electronic device body 7. Those skilled in the art will understand that the structure of the electronic device body 7 is not limited. In one embodiment, the electronic device body 7 includes a display screen 71 and a housing assembly 72. The display screen 71 is mounted on the housing assembly 72 and is used for displaying images and human-computer interaction. The housing assembly 72 supports the display screen 71 and has internal space for accommodating other electronic components. These electronic components include, but are not limited to, circuit boards, batteries, camera modules, microphones, and speakers; this application does not impose any limitations on these components.

[0147] In one embodiment, the housing assembly 72 includes a first housing 721, a second housing 722, and a hinge device 723. Both the first housing 721 and the second housing 722 have internal accommodating spaces to house electronic components. The first housing 721 and the second housing 722 are rotatably connected via the hinge device 723 and can rotate relative to each other, allowing the electronic device body 7 to present different usage states in different usage scenarios, including... Figures 3a-3b , Figures 5-6 The unfolded state shown and Figure 4 The folded state shown.

[0148] In one embodiment, when the electronic device body 7 is in the unfolded state, its opening angle is 180°, that is, the angle between the first housing 721 and the second housing 722 is 180°. Those skilled in the art will understand that the opening angle of the electronic device body 7 can also be 90°, 120°, 210°, etc., and this application does not limit this. Furthermore, the angles illustrated in this application are allowed to have slight deviations. For example, when the electronic device body 7 is in the unfolded state, the opening angle of the first housing 721 and the second housing 722 can be 180°, or approximately 180°, such as 170°, 175°, 185°, or 190°, etc. Other angles will be understood similarly below.

[0149] Furthermore, both the first housing 721 and the second housing 722 can rotate around the hinge device 723, allowing relative rotation between them. When the first housing 721 and the second housing 722 rotate relative to each other until they are coplanar, the electronic device body 7 is in an unfolded state, at which point the included angle between the first housing 721 and the second housing 722 is 180°. When the first housing 721 and the second housing 722 rotate relative to each other until they are stacked, the electronic device body 7 is in a folded state, at which point the included angle between the first housing 721 and the second housing 722 can be approximated as 0°.

[0150] It should be noted that this application does not limit the structure of the display screen 71 or the connection method between it and the housing assembly 72.

[0151] like Figures 3a-4 As shown, in one embodiment, a display screen 71 is disposed on one side of the housing assembly 72. The display screen 71 may be, but is not limited to, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, or a quantum dot light-emitting diode (QLED) display screen, etc. The display screen 71 is connected to one side surface of the housing assembly 72, and the side surface of the display screen 71 facing away from the housing assembly 72 is its display surface, which is used to display information and provide an interactive interface for the user.

[0152] In one embodiment, the display screen 71 includes a first portion 711, a second portion 712, and a foldable portion 713. The first portion 711 is connected to a first housing 721, the second portion 712 is connected to a second housing 722, and the foldable portion 713 is located between the first portion 711 and the second portion 712. During use, the first portion 711 and the second portion 712 remain in a planar state, while the foldable portion 713 can be bent to change the angle between the first portion 711 and the second portion 712, so that the display screen 71 folds or unfolds with the movement of the housing assembly 72, thereby enabling the foldable electronic device body 7 to switch between a folded state and an unfolded state. For example, in the display screen 71, at least a portion of the foldable portion 713 is made of a flexible material to allow the foldable portion 713 to be bent.

[0153] Driven by the hinge device 723, the display screen 71 opens or closes together with the first housing 721 and the second housing 722. The foldable portion 713 of the display screen 71 is flattened or bent, allowing the first portion 711 and the second portion 712 to rotate relative to each other. When the foldable electronic device body 7 is in the open state, the first portion 711 and the second portion 712 are in an unfolded state with their positions relatively far apart, the foldable portion 713 is flattened, and the display surfaces of the first portion 711 and the second portion 712 face the same direction. When the foldable electronic device body 7 is in the closed state, the first portion 711 and the second portion 712 are stacked relative to each other, the foldable portion 713 is bent, and the display surfaces of the first portion 711 and the second portion 712 face each other or away from each other.

[0154] It should be noted that the electronic device 200 provided in this application can be an outward-folding electronic device or an inward-folding electronic device. When the electronic device body 7 of the outward-folding electronic device is in a folded state, the display screen 71 surrounds the outer side of the housing assembly 72. Alternatively, it can be understood that the first part 711 and the second part 712 of the display screen 71 are arranged opposite to each other, and the housing assembly 72 is located between the first part 711 and the second part 712, with the display surfaces of the first part 711 and the second part 712 exposed to the user. When the electronic device body 7 of the inward-folding electronic device is in a folded state, the first part 711 and the second part 712 of the display screen 71 face each other, and the entire display screen 71 is housed inside the housing assembly 72, with the housing assembly 72 protecting the display screen 71 from the outside.

[0155] Furthermore, the bracket 81 is mounted on the housing assembly 72 and located on the back of the housing assembly 72 (the side of the housing assembly 72 facing away from the display screen 71 in the thickness direction of the electronic device 200). When the electronic device body 7 is in the unfolded state, its size is relatively large, making it inconvenient to hold for extended periods. The bracket 81 can support it for use on a desktop. It should be noted that the specific position of the bracket 81 on the housing assembly 72 is not limited; it can be mounted on the first housing 721, the second housing 722, or both. Figure 3b , Figures 5-6 As shown, in one embodiment, the bracket 81 is mounted on the first housing 721.

[0156] Those skilled in the art will understand that the mounting position of the bracket 81 on the first housing 721 and the cooperation relationship between the bracket 81 and the first housing 721 are not limited. The following describes the possible structures in conjunction with the accompanying drawings.

[0157] Please see Figures 7-10c , Figure 7 for Figure 3b A magnified view of part D in the middle; Figure 8This is a schematic diagram illustrating the cooperation relationship between the bracket and the housing in an electronic device according to an embodiment of this application, wherein the bracket is in the open state; Figure 9a This is a cross-sectional structural diagram of an electronic device according to an embodiment of this application, wherein the bracket is in a retracted state; Figure 9b This is a cross-sectional view of the electronic device according to an embodiment of this application, wherein the bracket is in the open state. Figure 10a This is a schematic diagram illustrating the cooperation relationship between the bracket, the pivot mechanism, and the step structure in an electronic device according to an embodiment of this application, wherein the bracket is in a retracted state; Figures 10b-10c This is a schematic diagram illustrating the cooperation relationship between the bracket, the pivot mechanism, and the step structure in an electronic device according to an embodiment of this application. The bracket is in the open state, and... Figure 10b and Figure 10c The angle at which the middle support opens is different.

[0158] It should be noted that, Figure 9a and Figure 9b This is a schematic diagram, intended only to show the cooperation relationship between the rotating shaft mechanism 100 and the bracket 81 and other components in the electronic device 200, and does not limit the specific structure of the electronic device 200.

[0159] like Figures 3a-10c As shown, the electronic device 200 also includes a pivot mechanism 100. The electronic device body 7 and the bracket 81 are rotatably connected via the pivot mechanism 100. The bracket 81 can rotate relative to the electronic device body 7 around a first axis Q1, switching between a stored state and an open state. The direction of the first axis Q1 is the axial direction of the bracket 81's rotation relative to the electronic device body 7. The first axis Q1 extends along a second direction Y, which is both the axial direction and the width direction of the bracket 81.

[0160] In one embodiment, the pivot mechanism 100 and the bracket 81 are arranged along a first direction X, which is perpendicular to the second direction Y. Alternatively, the pivot mechanism 100 and the bracket 81 are arranged in a direction perpendicular to the axis of rotation of the electronic device. Those skilled in the art will understand that the orientation of the bracket 81 on the electronic device body 7 is not limited. For example, one of the first direction X and the second direction Y can be the length direction of the electronic device 200, and the other can be the width direction of the electronic device 200. Alternatively, both the first direction X and the second direction Y can be inclined to the length direction of the electronic device 200, i.e., the bracket 81 is obliquely arranged on the electronic device body 7. In one embodiment, the first direction X is the width direction of the electronic device 200, and the second direction Y is the length direction of the electronic device 200. For ease of description, the thickness direction of the electronic device 200 is defined as the third direction Z, and the first direction X, the second direction Y, and the third direction Z are all mutually perpendicular.

[0161] For example, when the bracket 81 is in the retracted state, the bracket 81 is in close contact with the electronic device body 7, or it can be understood that the thickness direction of the bracket 81 is consistent with the thickness direction (third direction Z) of the electronic device 200. When the bracket 81 is in the open state, the bracket 81 is opened at a certain angle relative to the electronic device body 7, and the thickness direction of the bracket 81 is not consistent with the thickness direction of the electronic device body 7. The relative opening angle between the bracket 81 and the electronic device body 7 is not limited; it can be a specific angle or an arbitrary angle. For example, through the design of the damping structure in the pivot mechanism 100, the bracket 81 can be suspended at any angle within its allowable stroke range, supporting the electronic device body 7 at any angle. Alternatively, some limiting structures can be set to restrict the rotational stroke of the bracket 81, and in conjunction with the damping structure design, the bracket 81 can only be suspended at one or more set angles to support the electronic device body 7.

[0162] In one embodiment, a limiting structure can be provided between the bracket 81 and the electronic device body 7 (e.g., on the hinge mechanism 100). When the bracket 81 rotates relative to the electronic device body 7 to a specific angle (which can be designed according to the actual product size, such as 60°, 75°, 80°, etc., without specific limitations), the opening angle between the bracket 81 and the electronic device 200 reaches its maximum. At this point, the electronic device 200 is placed on the table for optimal use. In another embodiment, multiple limiting structures can be provided between the bracket 81 and the electronic device body 7. Each limiting structure corresponds to a specific angle. When the bracket 81 rotates to several specific angles, the damping force of the hinge mechanism 100 is relatively large, allowing the electronic device 200 to be placed on the table at several specific angles, meeting different usage needs. In yet another embodiment, a limiting structure is provided between the bracket 81 and the electronic device body 7. The limiting structure corresponds to a specific angle, allowing the bracket 81 to hover at any angle within its allowable travel range and support the electronic device body 7. The support of the electronic device body 7 is most effective when the bracket 81 is hovered at a specific angle.

[0163] Those skilled in the art will understand that the structure of the first housing 721 is not limited. The following description, in conjunction with the accompanying drawings, exemplarily illustrates the possible structures of the first housing 721 and the cooperative relationship between the bracket 81, the rotating shaft mechanism 100, and the first housing 721. It should be noted that, since the bracket 81 is mounted on the first housing 721 in the above embodiments, only the structure of the first housing 721 will be described below, and the structure of the second housing 722 will not be elaborated upon. The second housing 722 may adopt the same or different structure as the first housing 721, and this application does not impose any limitations on this.

[0164] like Figures 9a-10cAs shown, in one embodiment, the first housing 721 includes a middle frame 724 and a rear cover 725. The middle frame 724 includes a base plate 7242 and an outer frame 7241. The display screen 71 and the rear cover 725 are respectively mounted on both sides of the outer frame 7241 in the third direction Z (i.e., Figure 9a and Figure 9b The bottom plate 7242 is located between the display screen 71 and the back cover 725 (on both the top and bottom sides of the screen).

[0165] The back cover 725 of the electronic device body 7 has a cutout portion 7250. The pivot mechanism 100 and the bracket 81 are disposed on the base plate 7242 of the middle frame 724, and are correspondingly disposed within the cutout portion 7250 of the back cover 725 in the third direction Z. Alternatively, it can be understood that a portion of the back cover 725 is cut out to accommodate the bracket 81 and the pivot mechanism 100 mounted on the base plate 7242 of the middle frame 724.

[0166] It should be noted that the specific structure of the bracket 81 is not limited. In one embodiment, the bracket 81 includes a bracket body 811 and a mounting member 812. The bracket body 811 is configured as a plate-like structure, and the mounting member 812 is connected to the bracket body 811 and located on the side of the bracket body 811 facing the display screen 71 in the third direction Z. The hinge mechanism 100 is mounted on the mounting member 812 of the bracket 81. The bracket body 811 is a structure for supporting the electronic device body 7, while the mounting member 812 is mainly used for connecting with the hinge mechanism 100. In the third direction Z, both the hinge mechanism 100 and the mounting member 812 are located on the side of the bracket body 811 facing the display screen 71. With this structure, there is a height difference between the bracket body 811 and the hinge mechanism 100, which facilitates hiding the hinge mechanism 100 within the electronic device body 7. In one embodiment, when the bracket 81 is in the retracted state, the bracket body 811 is entirely embedded in the cutout portion 7250 of the back cover 725. Alternatively, it can be understood that, in the third direction Z, the bracket body 811 is entirely located within the cutout portion 7250. When the bracket 81 is in the open state, at least a portion of the structure of the bracket body 811 detaches from the cutout portion 7250 and protrudes from the outer surface of the electronic device body 7; that is, the bracket body 811 and the electronic device body 7 are relatively open. With this structure, when the bracket 81 is in the retracted state, the bracket body 811 can be embedded within the electronic device body 7 without protruding from it. The bracket 81 does not increase the local thickness of the electronic device 200, making the electronic device 200 thinner and lighter.

[0167] like Figure 9a As shown, in one embodiment, when the bracket 81 is in the closed state, in the first direction X, the bracket 81 is located between the two outer frame edges 7241 of the middle frame 724, and the end of the bracket 81 away from the first axis Q1 is connected to that side ( Figure 9aThe outer frame 7241 (right side) is clearance-fitted. In other alternative embodiments, the bracket 81 may also extend to the outer frame 7241, for example, by... Figure 9a A portion of the outer frame 7241 on the right side is hollowed out to accommodate the bracket 81, but this application does not limit this.

[0168] like Figures 9a-10c As shown, in one embodiment, the electronic device body 7 further includes a cover plate 82 disposed within the cutout portion 7250 of the rear cover 725. The cover plate 82 is disposed along the first direction X on the side of the bracket 81 facing the pivot mechanism 100 and is connected to the bracket body 811, so that the cover plate 82 and the bracket 81 constitute a bracket structure 8. When the bracket 81 is in the retracted state, the projection of the bracket structure 8 along the third direction Z on the display screen 71 coincides with the projection of the cutout portion 7250 along the third direction Z on the display screen 71. Alternatively, it can be understood that the cover plate 82 covers the pivot mechanism 100, hiding the pivot mechanism 100 inside the electronic device body 7, so that the user cannot directly see the pivot mechanism 100 from the outside. Furthermore, the support structure 8, composed of the cover plate 82 and the bracket 81, is laid in the hollow portion 7250 of the rear cover 725. When the bracket 81 is in the retracted state, the support structure 8 completely overlaps with the hollow portion 7250 in the third direction Z. The four sides of the support structure 8 are connected to the solid structure of the rear cover 725, so that the display screen 71, the housing, and the bracket 81 of the electronic device 200 form a closed structure, and the user cannot observe the internal components of the electronic device 200. Those skilled in the art will understand that the cover plate 82 is for shielding and protecting the hinge mechanism 100. The cover plate 82 can be set separately or integrally formed with the rear cover 725; this application does not limit this. In one example scenario, when the cover plate 82 is integrally formed with the rear cover 725, a portion of the structure of the rear cover 725 can be reused as the cover plate, and the hollow portion 7250 of the rear cover 725 can be used only to accommodate the bracket 81.

[0169] In one embodiment, on the third direction Z, the surface of the cover plate 82 away from the display screen 71 and the surface of the rear cover 725 away from the display screen 71 are in the same plane. When the bracket 81 is in the retracted state, the surface of the bracket 81 away from the display screen 71 is also in the same plane as the surface of the rear cover 725 away from the display screen 71. Alternatively, it can be understood that in... Figures 9a-10c From this perspective, when the bracket 81 is in the retracted state, the upper surface of the bracket body 811 is flush with the upper surface of the back cover 725, which ensures the flatness and smoothness of the outer surface of the electronic device 200, making the thickness of the electronic device 200 more uniform, simple and beautiful, and with a good feel. In other alternative embodiments, the upper surface of the bracket structure 8 may not be flush with the upper surface of the back cover 725, and this application does not limit this.

[0170] It should be noted that, for the sake of aesthetic appeal, the shapes of the bracket 81 and the cover 82 can be designed to give the back cover 725 of the electronic device a specific shape. The bracket 81 and the cover 82 can be fitted together through a gap or by any other shaped component; this application does not impose any limitations on this. For example, as... Figure 7 As shown, in one embodiment, a crossbeam 726 is provided between the bracket 81 and the cover plate 82, so that the bracket 81, cover plate 82 and crossbeam 726 present an H-shaped structure, which is simple and beautiful in appearance. The crossbeam 726 can be integrally formed with the rear cover 725 or it can be a separate structure; this application does not limit this. In other alternative embodiments, the crossbeam 726 may not be provided between the bracket 81 and the cover plate 82, and the bracket 81 and cover plate 82 can also be designed with other shapes, which can be set as needed.

[0171] Those skilled in the art will understand that when the bracket 81 is in the retracted state, the bracket 81, together with the cover plate 82, can close the cutout 7250 on the back cover 725. However, when the bracket 81 is in the open state, an opening will appear between the bracket body 811 and the electronic device body 7, exposing the cutout 7250 on the back cover 725 and thus exposing the internal structure of the electronic device 200. To solve this problem, some shielding structures can be provided in the electronic device body 7.

[0172] like Figures 8-10c As shown, in one embodiment, a stepped structure 9 is provided on the base plate 7242 of the middle frame 724. The stepped structure 9 is connected to the base plate 7242 and is located on the side of the base plate 7242 away from the display screen 71 in the third direction Z. The bracket 81 is mounted on the base plate 7242 of the middle frame 724 via the stepped structure 9. The stepped structure 9 includes a top surface 91 and a side surface 92 that are perpendicular to each other. The side surface 92 extends in the third direction Z, and the top surface 91 is connected to the end of the side surface 92 away from the display screen 71 in the third direction Z. When the bracket 81 is in the retracted state, the top surface 91 is opposite to the bracket body 811 of the bracket 81. When the bracket 81 is in the open state, an opening is formed between the bracket body 811 and the top surface 91 of the stepped structure 9. Alternatively, it can be understood that the step structure 9 is set between the bracket body 811 and the base plate 7242 of the middle frame 724. The step structure 9 has a certain thickness. When the bracket body 811 is rotated open, the top surface 91 of the step structure 9 can cover the opening between the bracket body 811 and the electronic device body 7, so that the user can see the top surface 91 of the step structure 9 instead of other electronic components in the electronic device 200. This improves the aesthetics of the electronic device while protecting the electronic components of the electronic device 200.

[0173] It should be noted that this application does not limit the specific structure of the step structure 9, which can be a straight plate structure, an "L-shaped" plate structure, etc. The step structure 9 can be integrally formed with the base plate 7242 of the middle frame 724, or it can be designed separately, with the step structure 9 installed on the base plate 7242. This application does not limit this.

[0174] Furthermore, since the bracket 81 is connected to the rotating shaft structure 100, the connection between the bracket 81 and the rotating shaft mechanism 100 is made through a connecting member or other structure. This connection cannot be concealed by the step structure 9. When the bracket 81 is opened, the connection between the rotating shaft mechanism 100 and the bracket 81 will still be exposed. The rotating shaft mechanism 100 can be concealed by the shape design of the mounting member 812 on the bracket 81.

[0175] like Figures 8-10c As shown, in one embodiment, the mounting member 812 of the bracket 81 is configured as an arc-shaped structure. When the bracket 81 is in the retracted state, the mounting member 812 is located on the side 92 of the stepped structure 9 facing the cover plate 82 in the first direction X. When the bracket 81 is in the open state, at least a portion of the structure of the mounting member 812 is located on the side 92 of the stepped structure 9 facing away from the cover plate 82 in the first direction X. Alternatively, it can be understood that the arc-shaped mounting member 812 is located in the gap between the stepped structure 9 and the pivot mechanism 100. When the bracket 81 rotates, the arc-shaped structure also rotates within the gap. When the bracket body 811 is opened at a certain angle relative to the electronic device body 7, the arc-shaped structure is also exposed along with the bracket body 811, shielding the gap between the stepped structure 9 and the pivot mechanism 100, and also shielding the gap between the bracket body 811 and the pivot mechanism 100, thus providing all-round shielding of the pivot mechanism 100.

[0176] Those skilled in the art will understand that the bracket 81 rotates relative to the electronic device body 7 about the first axis Q1, and the position of the first axis Q1 is not limited.

[0177] like Figures 3a-10c As shown, in one embodiment, the first axis Q1 is located on the surface of the bracket structure 8 in the third direction Z, away from the display screen 71, and at the seam between the cover plate 82 and the bracket body 811. During the rotation of the bracket 81 relative to the electronic device body 7, the upper surface of the bracket body 811 and the upper surface of the cover plate 82 are always in contact through a gap, resulting in a clean and aesthetically pleasing appearance and smooth surface transitions for the electronic device 200. In other alternative embodiments, the first axis Q1 may also be located outside the surface of the bracket structure 8, or outside the seam between the cover plate 82 and the bracket body 811, etc., and this application does not impose any limitations on this.

[0178] The preceding text mainly describes the structure of the electronic device 200 to roughly illustrate the cooperation relationship between the bracket 81 and the electronic device body 7, as well as the application scenario of the rotating mechanism 100 provided in this application. The following text, in conjunction with the accompanying drawings, further explains the principle and structure of the rotating mechanism 100.

[0179] Please see Figures 11-12 , Figures 11-12 This is a schematic diagram of the principle structure of the rotating shaft mechanism in an embodiment of this application.

[0180] like Figures 11-12 As shown, the pivot mechanism 100 provided in this embodiment can be used to connect a first component E and a second component F. The first component E can rotate relative to the second component F about a first axis Q1. In one embodiment, the first component E is a bracket 81, and the second component F is an electronic device body 7, so that the electronic device body 7 and the bracket 81 are rotatably connected by the pivot mechanism 100. In another alternative embodiment, the first component E can also be the electronic device body 7, and the second component F can also be the bracket 81; this application does not limit this. It should be understood that the first component E mentioned below can refer to the bracket 81, and the second component F can refer to the electronic device body 7; this will not be repeated hereafter.

[0181] The rotating shaft mechanism 100 includes a first damping structure 1, a second damping structure 2, and a connecting member 3. The first damping structure 1 is mounted on the first component E. The first damping structure 1 and the second damping structure 2 are spaced apart in the first direction X and connected by the connecting member 3. The first damping structure 1 can rotate relative to the second component F around the first axis Q1 under the drive of the first component E, and the second damping structure 2 can rotate relative to the second component F around the second axis Q2 via the connecting member 3. Both the first axis Q1 and the second axis Q2 extend along the second direction Y.

[0182] The rotating shaft mechanism 100 provided in this embodiment of the application is provided with two damping structures, which are linked by a connector 3. When the first component E and the second component F rotate relative to each other, both damping structures provide damping force. The damping forces of each damping structure are superimposed and can be used to support the second component F, for example, the bracket 81 supports the electronic device body 7. The first damping structure 1 and the second damping structure 2 are arranged along the first direction X, while the bracket 81 rotates relative to the electronic device body 7 around the first axis Q1. The first axis Q1 extends along the second direction Y. The first direction X and the second direction Y are perpendicular to each other. It can be understood that the arrangement direction of the two damping structures is perpendicular to the axis of rotation of the bracket 81.

[0183] With this structure, the bracket 81 is mounted only on the first damping structure 1, and the width of the bracket 81 (its dimension in the second direction Y) is only related to the dimension of the first damping structure 1 in the second direction Y. However, the supporting force of the bracket 81 on the electronic device body 7 is the sum of the damping forces of the first damping structure 1 and the second damping structure 2. When the damping force of the first damping structure 1 is insufficient, the second damping structure 2 can compensate. Therefore, the dimension of the first damping structure 1 can be reduced in the second direction Y, and the width d of the bracket 81 can also be reduced accordingly. At the same time, the second damping structure 2 can be designed to be larger to provide sufficient damping force and ensure the stability of the bracket 81 when supporting the electronic device body 7.

[0184] As can be seen, the pivot mechanism 100 provided in this application embodiment can provide a large damping force when the width of the bracket 81 of the electronic device 200 is small, and can take into account both the stability of the bracket 81 support and the miniaturized design.

[0185] Those skilled in the art will understand that the specific structures of the first damping structure 1, the second damping structure 2, and the connecting member 3 are not limited. The following description, in conjunction with the accompanying drawings, illustrates the possible structures that may be adopted.

[0186] Please see Figures 13-18b , Figure 13 This is a three-dimensional structural diagram of the rotating shaft mechanism according to an embodiment of this application; Figure 14 This is a top view of the rotating shaft mechanism according to an embodiment of this application; Figure 15 For along Figure 14 Schematic diagram of the cross-sectional structure along the AA direction; Figure 16 For the rotating shaft mechanism of this application embodiment, in another state along Figure 14 Schematic diagram of the cross-sectional structure along the AA direction; Figure 17 This is an exploded structural diagram of the rotating shaft mechanism according to an embodiment of this application; Figure 18a This is a schematic diagram of the connection structure of the first damping structure, the second damping structure, and the connecting member in the rotating shaft mechanism of this application embodiment; Figure 18b This is a schematic diagram of the connection structure of the first damping structure, the second damping structure, and the connecting member in the rotating shaft mechanism of this application embodiment at another angle.

[0187] like Figures 11-18bAs shown, in one embodiment, the first damping structure 1 includes a first rotating shaft 11 and a first sleeve 12. The first rotating shaft 11 is sleeved inside the first sleeve 12 and can rotate relative to the first sleeve 12 about a third axis Q3. The second damping structure 2 includes a second rotating shaft 21 and a second sleeve 22. The second rotating shaft 21 is sleeved inside the second sleeve 22 and can rotate relative to the second sleeve 22 about a fourth axis Q4. Both the third axis Q3 and the fourth axis Q4 extend along a second direction Y. The first sleeve 12 and the second sleeve 22 are both connected to and fixed relative to the connecting member 3, so as to connect the first damping structure 1 and the second damping structure 2 through the connecting member 3.

[0188] The first rotating shaft 11 is mounted on the first component E, i.e., the bracket 81 of the electronic device 200 is connected to the first rotating shaft 11. When the bracket 81 is needed, the user can manually rotate it. The bracket 81 drives the first rotating shaft 11 to rotate relative to the first sleeve 12 within the first sleeve 12. The friction between the two generates a damping force in the first damping structure 1. Simultaneously, the first rotating shaft 11 and the first sleeve 12 rotate around the first axis Q1, driving the second rotating shaft 21 and the second sleeve 22 to rotate around the second rotating shaft 21. The second rotating shaft 21 rotates relative to the second sleeve 22 within the second sleeve 22, and the friction between them generates a damping force in the second damping structure 2. Both the first sleeve 12 and the second sleeve 22 are connected to and fixed relative to the connecting member 3, so as to connect the first damping structure 1 and the second damping structure 2 through the connecting member 3.

[0189] Wherein, the first axis Q1 is the axis of rotation of the first damping structure 1 relative to the second component F, and also the axis of rotation of the first component E relative to the second component F, that is, the axis of rotation of the bracket 81 relative to the electronic device body 7. The second axis Q2 is the axis of rotation of the second damping structure 2 relative to the second component F. The first axis Q1 and the second axis Q2 are parallel to each other, and may coincide or not coincide, which is not limited in this application. The third axis Q3 is the axis of rotation of the first rotating shaft 11 relative to the first sleeve 12, and is also the axis of the first rotating shaft 11. The fourth axis Q4 is the axis of rotation of the second rotating shaft 21 relative to the second sleeve 22, and is also the axis of the second rotating shaft 21. Since the first axis Q1 and the second axis Q2 are parallel, and the first sleeve 12 and the second sleeve 22 are connected by the connector 3, the third axis Q3 and the fourth axis Q4 are also parallel to each other and both extend along the second direction Y.

[0190] In one embodiment, the first axis Q1, the second axis Q2, the third axis Q3, and the fourth axis Q4 are spaced apart from each other. The distance between the first axis Q1 and the second axis Q2 is equal to the distance between the third axis Q3 and the fourth axis Q4, and the distance between the first axis Q1 and the third axis Q3 is equal to the distance between the second axis Q2 and the fourth axis Q4. Alternatively, it can be understood that in a plane perpendicular to the second direction Y, the first axis Q1, the second axis Q2, the third axis Q3, and the fourth axis Q4 form a parallelogram structure. In the parallelogram structure, the side between the first axis Q1 and the second axis Q2 is fixed, the side between the first axis Q1 and the third axis Q3 rotates, the side between the second axis Q2 and the fourth axis Q4 rotates, and the side between the third axis Q3 and the fourth axis Q4 moves while always remaining parallel to the side between the first axis Q1 and the second axis Q2. That is, the second component F, the first damping structure 1, the second damping structure 2, and the connecting member 3 form a four-bar structure.

[0191] In other alternative embodiments, the axes can be arranged in other positional relationships. For example, the first axis Q1 can coincide with the second axis Q2. In a plane perpendicular to the second direction Y, the first axis Q1 (second axis Q2), the third axis Q3, and the fourth axis Q4 form a triangular structure, and the entire triangular structure can rotate around the first axis Q1. In this case, the distance between the first axis Q1 (second axis Q2) and the third axis Q3, and the distance between the first axis Q1 (second axis Q2) and the fourth axis Q4, can be equal or unequal, and this application does not impose any restrictions on this.

[0192] As mentioned above, the electronic device 200 can be equipped with some limiting structures to limit the opening angle of the bracket 81 relative to the electronic device body 7, or to remind the user of the optimal angle for the bracket 81 to support the electronic device body 7. These limiting structures can be set in the pivot mechanism 100, or more specifically, on the damping structure, using the shape of the damping structure itself for limiting.

[0193] like Figures 15-18b As shown, in one embodiment, the first sleeve 12 is provided with a first limiting part 13, and the outer surface of the first rotating shaft 11 along its circumference is set as a plane. The first limiting part 13 is an elastic structure (such as a spring sheet, which is not limited in this application). When the first rotating shaft 11 rotates relative to the first sleeve 12 to the first position ( Figures 18a-18b(As shown in the diagram), the first limiting part 13 and the first rotating shaft 11 are engaged by a planar fit. Alternatively, it can be understood that an elastic first limiting part 13 is provided between the first rotating shaft 11 and the first sleeve 12. Along the circumference of the first rotating shaft 11, a portion of its outer surface is arc-shaped, and another portion is flat. When the first rotating shaft 11 rotates relative to the first sleeve 12, both the arc-shaped and flat surfaces can engage with the first limiting part 13. When the first rotating shaft 11 engages with the first limiting part 13 via the arc-shaped surface, the first limiting part 13 is compressed by the first rotating shaft 11 into a sheet-like structure close to the inner wall of the first sleeve 12. At this time, the friction between the first rotating shaft 11 and the first sleeve 12 is small, the damping force of the first damping structure 1 is small, and the user rotates the bracket 81 more smoothly and effortlessly. When the first rotating shaft 11 engages with the first limiting part 13 via the plane, the first limiting part 13 springs back to a planar shape. At this time, the friction between the first rotating shaft 11 and the first sleeve 12 is relatively large, and the damping force of the first damping structure 1 is relatively large, making it more difficult for the user to rotate. The first position refers to the limiting position of the first damping structure 1. There can be one or more first positions, each corresponding to a specific angle. For example, the first damping structure 1 can be set such that at a specific angle (e.g., the bracket 81 is opened 60°, 70°, 75°, etc. relative to the electronic device body 7, the specific angle is not limited), the first rotating shaft 11 engages with the first limiting part 13 via the plane, and the user's rotation of the bracket 81 changes from smooth to difficult. At this specific angle, placing the electronic device 200 on a table provides stable support and a better user experience.

[0194] In other alternative embodiments, the first limiting part 13 can also adopt other structures. For example, a groove can be provided in the inner wall of the first sleeve 12, and the first limiting part 13 can be an elastic element provided in the groove. When the arc surface of the first rotating shaft 11 rotates to be opposite to the groove on the inner wall of the first sleeve 12, the arc surface compresses the elastic element into the groove, the friction between the first rotating shaft 11 and the first sleeve 12 is small, and the damping force of the first damping structure 1 is small. When the plane of the first rotating shaft 11 is opposite to the groove on the inner wall of the first sleeve 12 (i.e., the first rotating shaft 11 rotates relative to the first sleeve 12 to the first position), the elastic element pops out of the groove, protrudes from the inner wall surface of the first sleeve 12 and abuts against the plane of the first rotating shaft 11, the friction between the first rotating shaft 11 and the first sleeve 12 is large, and the damping force of the first damping structure 1 is large. The elastic element can be a spring sheet or other structure that is elastic in itself, or it can be an elastic structure composed of a spring and a protrusion. For example, the protrusion and the spring can be installed in the groove of the first sleeve 12, with one end of the spring connected to the bottom of the groove and the other end connected to the protrusion. The protrusion cooperates with the first rotating shaft 11.

[0195] In one embodiment, the second sleeve 22 is provided with a second limiting part 23, and a portion of the outer surface of the second rotating shaft 21 along its circumference is formed as a plane. The second limiting part 23 is an elastic structure. When the second rotating shaft 21 rotates relative to the second sleeve 22 to a second position, the second limiting part 23 and the second rotating shaft 21 are engaged through a planar fit. The second position is the limiting position of the second damping structure 2, i.e. Figures 18a-18b The position is shown in the figure. The function and working principle of the second limiting part 23 are the same as those of the first limiting part 13, and will not be repeated here. This application does not limit the specific structure of the second limiting part 23, and it can be designed with reference to the first limiting part 13.

[0196] Those skilled in the art will understand that only one of the first damping structure 1 and the second damping structure 2 may be provided with a limiting part, while the other may not be provided with a limiting part, or both damping structures may be provided with limiting parts. This application does not impose any restrictions on this.

[0197] In one embodiment, multiple limiting parts can be provided in the first damping structure 1 or the second damping structure 2, each limiting part corresponding to a different set angle. The specific number of limiting parts in each damping structure is not limited, and can be one, two, three or more. In an example scenario, two first limiting parts 13 can be provided in the first damping structure 1. When the bracket 81 is opened 45° relative to the electronic device body 7, the first rotating shaft 11 and one of the first limiting parts 13 are in planar engagement. When the bracket 81 is rotated further to open 60° relative to the electronic device body 7, the first rotating shaft 11 and the other first limiting part 13 are in planar engagement. At both specific angles, the damping force of the rotating shaft mechanism 100 is relatively large, and the bracket 81 can stably support the electronic device body 7. Users can choose according to their height, the height of the table, and other scenarios. In an alternative embodiment, limiting parts can also be provided in the first damping structure 1 and the second damping structure 2 respectively. The limiting parts in the first damping structure 1 and the second damping structure 2 can correspond to different angles and usage scenarios, and this application does not limit this.

[0198] Those skilled in the art will understand that the specific structure of the connector 3 is not limited. The connector 3 can be fixedly connected to the first sleeve 12 and the second sleeve 22. The first sleeve 12 and the connector 3 can be integrally formed or have a separate structure. The second sleeve 22 and the connector 3 can be integrally formed or have a separate structure; this application does not impose any restrictions in this regard. Figures 13-18b As shown, in one embodiment, the connector 3 is configured as a connecting rod, and the two ends of the connecting rod are respectively formed into a first sleeve 12 and a second sleeve 22. That is, the first sleeve 12 and the second sleeve 22 are integrally formed with the connector 3, which has a simple structure and is easy to process.

[0199] Those skilled in the art will understand that the rotating shaft mechanism 100 needs to be installed on the second component F and connected to the first component E in order to rotatably connect the first component E and the second component F. Various structures for connection and fixation can be provided between the rotating shaft mechanism 100 and the second component F, as well as between the first component E and the rotating shaft mechanism 100. This application does not limit the connection method between the rotating shaft mechanism 100 and the second component F and the first component E. The following describes the possible structures in conjunction with the accompanying drawings.

[0200] Please see Figures 19-23 , Figure 19 This is a schematic diagram of the structure of the first fixing member in the rotating shaft mechanism of this application embodiment; Figure 20 This is a schematic diagram of the connection structure between the first fixing member and the first damping structure in the rotating shaft mechanism of this application embodiment; Figure 21 This is a schematic diagram of the structure of the second fixing member in the rotating shaft mechanism of this application embodiment; Figure 22 This is a schematic diagram showing the cooperation relationship between the first and second fixing members in the rotating shaft mechanism of this application embodiment; Figure 23 This is a schematic diagram showing the cooperation relationship between the second fixing member and the second damping structure in the rotating shaft mechanism of this application embodiment.

[0201] like Figures 13-23 As shown, in one embodiment, the rotating shaft mechanism 100 further includes a first fixing member 4 and a second fixing member 5. The first fixing member 4 is fixed to the first component E, and the first rotating shaft 11 of the first damping structure 1 is mounted on the first fixing member 4, allowing the first damping structure 1 to be mounted to the first component E. The second fixing member 5 is fixed to the second component F, and the second rotating shaft 21 of the second damping structure 2 is mounted on the second fixing member 5, allowing the second damping structure 2 to be mounted to the second component F.

[0202] Furthermore, the first fixing member 4 can rotate relative to the second fixing member 5 about the first axis Q1, so that the first component E can rotate relative to the second component F about the first axis Q1. For example, the second fixing member 5 is fixed to the electronic device body 7, and the bracket 81 is fixed to the first fixing member 4 and rotatably connected to the second fixing member 5 through the first fixing member 4, and further rotatably connected to the electronic device body 7. When the user rotates the bracket 81, the bracket 81 drives the first fixing member 4 to rotate relative to the second fixing member 5. Since the second fixing member 5 is fixed relative to the electronic device body 7, the first fixing member 4 also rotates relative to the electronic device body 7, and the bracket 81 rotates relative to the electronic device body 7. In some alternative embodiments, the first fixing member 4 may not be provided in the rotating shaft mechanism 100. For example, the first component E may be directly mounted on the first rotating shaft 11. The second fixing member 5 may also not be provided in the rotating shaft mechanism 100. For example, the second damping structure 2 may be directly mounted on the second component F. This application does not limit this.

[0203] It should be noted that the specific shapes of the first fixing member 4 and the second fixing member 5 are not limited. For example... Figure 13 , Figure 17 , Figures 21-23 As shown, in one embodiment, the second fixing member 5 includes a base 51 extending along the second direction Y, and two extension arms 52 respectively connected to both ends of the base 51 along the second direction Y. Each of the two extension arms 52 extends along the first direction X and protrudes from the base 51 to the same side, such that the two extension arms 52 and the base 51 surround to form an installation space 50. The first damping structure 1, the second damping structure 2, the connector 3, and the first fixing member 4 are all installed within the installation space 50. In the first direction X, the second damping structure 2 is located on the side of the first damping structure 1 closer to the base 51, and the first fixing member 4 is located on the side of the first damping structure 1 away from the base 51. Alternatively, it can be understood that the second fixing member 5 is a U-shaped structure in general, and the second damping structure 2, the first damping structure 1, and the first fixing member 4 are arranged sequentially along the first direction X within the U-shaped structure, with the second damping structure 2 close to the base 51 of the second fixing member 5.

[0204] In this embodiment, each part of the second fixing member 5 along its extension direction can be fixedly connected to the second component F. In one embodiment, the base 51 and each extension arm 52 of the second fixing member 5 can be fixedly connected to the second component F. The base 51 is provided with multiple fixing holes 510, and the base 51 can be fixedly connected to the second component F using fasteners such as screws and bolts. The extension arm 52 is provided with an extension platform 521 protruding from the extension arm 52, and the extension platform 521 is also provided with fixing holes 5210, and the extension arm 52 can be fixedly connected to the second component F using fasteners such as screws and bolts. Those skilled in the art will understand that the number of fixing holes 510 on the base 51 is unlimited, as are the number of extension platforms 521 on the extension arm 52 and the number of fixing holes 5210 on the extension platforms 521, and can be configured as needed.

[0205] Those skilled in the art will understand that the second fastener 5 can be an integral structure or a split structure. In one embodiment, the second fastener 5 has two fastening portions 53, each of which includes a first portion 531 extending along the second direction Y and a second portion 532 extending along the first direction X. The first portion 531 and the second portion 532 are connected, and the first portions 531 of the two fastening portions 53 are connected and fixedly joined to form the base 51 of the second fastener 5. The second portions 532 of the two fastening portions 53 respectively form two extension arms 52 of the second fastener 5. Alternatively, it can be understood that the second fastener 5 is split from the base 51 into two fastening portions 53, each fastening portion 53 including an extension arm 52 and a portion of the base 51. The two fastening portions 53 can be fixedly connected by welding, bolting, bonding, riveting, etc., and there is no specific limitation. In one embodiment, the mating surfaces of the two fixing parts 53 are configured as two inverted L-shaped structures. The fastener passes through the fixing hole 510 at the corresponding position on the base 51, and can pass through the two fixing parts 53 at the same time, so as to firmly connect the two fixing parts 53.

[0206] like Figure 13 , Figure 17 , Figures 19-20 , Figure 22 As shown, in one embodiment, the first fixing member 4 includes a base 41, which is fixedly connected to the first component E. The specific connection method between the base 41 and the first component E will be described later in conjunction with the structural description of the bracket 81, and will not be elaborated here.

[0207] In one embodiment, the first fixing member 4 is further provided with a mounting part 42, the mounting part 42 is mounted with the first rotating shaft 11, the mounting part 42 is connected to the base 41, and protrudes from the base 41 in the first direction X toward the side where the first damping structure 1 is located. The first rotating shaft 11 of the first damping structure 1 is mounted on the mounting part 42 so as to connect the first component E to the first rotating shaft 11 through the mounting part 42.

[0208] It should be noted that the specific structure of the mounting part 42 is not limited. In one embodiment, the mounting part 42 includes two protrusions 421 spaced apart in the second direction Y. The first damping structure 1 is located between the two protrusions 421. Each of the two protrusions 421 has a through hole. The two ends of the first rotating shaft 11 in the first damping structure 1 protrude from the first sleeve 12 and pass through the through holes of the two protrusions 421 respectively. As can be seen from the above, the first rotating shaft 11 can rotate relative to the second fixing member 5 together with the first fixing member 4. The first rotating shaft 11 and the first fixing member 4 only need to be relatively fixed in a plane perpendicular to the second direction Y. The first rotating shaft 11 can rotate relative to the first fixing member 4 around the third axis Q3 in the through holes of the two protrusions 421, or it can be completely fixedly connected to the first fixing member 4. This application does not limit this. In one embodiment, the two ends of the first rotating shaft 11 are fixedly connected to two bosses 421, meaning the first rotating shaft 11 is completely fixedly connected to the first fixing member 4. This prevents the first rotating shaft 11 from sliding in the through holes of the first sleeve 12 and the bosses 421, making the connection more reliable and better transmitting the damping force of the first damping structure 1 to the first component E. The fixing method between the first rotating shaft 11 and the bosses 421 is not limited; they can be fixed by bonding, welding, structural positioning, etc. In one embodiment, a portion of the outer peripheral surface of the first rotating shaft 11 can be made into a plane, and the corresponding positions on the inner wall surfaces of the through holes 4210 on each boss 421 can be made into planes. The first rotating shaft 11 and each boss 421 are fitted together by planes, restricting their relative rotation.

[0209] It should be noted that the rotation of the first fixing member 4 relative to the second fixing member 5 is not limited. For example, a connecting shaft can be provided between the first fixing member 4 and the second fixing member 5, and the connecting shaft can rotate relative to the second fixing member 5 about the first axis Q1, so that the first fixing member 4 can rotate relative to the second fixing member 5. In one embodiment, the first fixing member 4 is slidably connected to the second fixing member 5, so that the first fixing member 4 can rotate relative to the second fixing member 5 about the first axis Q1, and the first damping structure 1 can rotate relative to the second fixing member 5 under the drive of the first fixing member 4.

[0210] Specifically, in one embodiment, the first fixing member 4 further includes two rotating arms 43, which are disposed at both ends of the base 41 along the second direction Y and are respectively connected to both ends of the base 41. Furthermore, the two rotating arms 43 correspond one-to-one with the two extension arms 52 of the second fixing member 5. Each of the two rotating arms 43 is slidably connected to its corresponding extension arm 52 via a first sliding structure 61, so that the first fixing member 4 can rotate relative to the second fixing member 5 about the first axis Q1. The first sliding structure 61 includes an arc-shaped groove 611 and an arc-shaped slider 612 that are slidably connected to each other. One of the arc-shaped groove 611 and the arc-shaped slider 612 of the first sliding structure 61 is disposed on the rotating arm 43 of the first fixing member 4, and the other is disposed on the extension arm 52 of the second fixing member 5. The arc-shaped slider 612 slides along the arc-shaped track in the arc-shaped groove 611. The first axis Q1 passes through the center of the arc-shaped track, and the first fixing member 4 can rotate relative to the second fixing member 5 around the first axis Q1. Then the first component E and the first damping structure 1 can rotate relative to the second component F around the first axis Q1.

[0211] In one embodiment, the arc-shaped groove 611 of the first sliding structure 61 is disposed on the rotating arm 43 of the first fixing member 4, and the arc-shaped slider 612 is disposed on the extension arm 52 of the second fixing member 5. In an alternative embodiment, the arc-shaped groove 611 of the first sliding structure 61 may also be disposed on the extension arm 52 of the second fixing member 5, and the arc-shaped slider 612 may also be disposed on the rotating arm 43 of the first fixing member 4; this application does not limit this.

[0212] Those skilled in the art will understand that since the second rotating shaft 21 is mounted on the second fixed member 5, if the second rotating shaft 21 can rotate relative to the second fixed member 5, then the second damping structure 2 can also rotate relative to the second component F. Similarly, the manner in which the second rotating shaft 21 rotates relative to the second fixed member 5 is not limited. In one embodiment, the second damping structure 2 is slidably connected to the second fixed member 5, allowing the second damping structure 2 to rotate relative to the second fixed member 5 about the second axis Q2.

[0213] Specifically, such as Figure 17 , Figure 23As shown, in one embodiment, the second damping structure 2 further includes two bushings 24 spaced apart along the second direction Y, with the two bushings 24 respectively fitted onto both ends of the second rotating shaft 21. The two bushings 24 correspond one-to-one with the two extension arms 52 of the second fixing member 5. Each bushing 24 is slidably connected to its corresponding extension arm 52 via a second sliding structure 62, allowing the second damping structure 2 to rotate relative to the second fixing member 5 about the second axis Q2. The second sliding structure 62 includes an arc-shaped slider 622 and an arc-shaped groove 621 slidably connected to each other. One of the arc-shaped slider 622 and the arc-shaped groove 621 of the second sliding structure 62 is disposed on the bushing 24, and the other is disposed on the extension arm 52 of the second fixing member 5. The arc-shaped slider 622 slides along the arc-shaped track in the arc-shaped groove 621. The second axis Q2 passes through the center of the arc-shaped track. The second rotating shaft 21 can rotate around the second axis Q2 relative to the second fixed member 5 through the bushing 24. Then the second damping structure 2 can rotate around the second axis Q2 relative to the second component F.

[0214] In one embodiment, the arc-shaped slider 622 of the second sliding structure 62 is disposed on the bushing 24, and the arc-shaped groove 621 is disposed on the extension arm 52 of the second fixing member 5. In an alternative embodiment, the arc-shaped slider 622 of the second sliding structure 62 may also be disposed on the extension arm 52 of the second fixing member 5, and the arc-shaped groove 621 may also be disposed on the bushing 24; this application does not limit this.

[0215] The above mainly describes the cooperation relationship between the bracket 81 and the electronic device body 7 in the electronic device 200, as well as the specific structure of the rotating mechanism 100. The following describes the installation method between the rotating mechanism 100 and the bracket 81 with reference to the accompanying drawings.

[0216] Please see Figures 24-26b , Figure 24 This is an exploded structural diagram of the rotating shaft mechanism and the support frame according to an embodiment of this application; Figure 25 This is a schematic diagram of the connection structure between the rotating shaft mechanism and the bracket in an embodiment of this application; Figure 26a for Figure 25 Cross-sectional view along the BB direction; Figure 26b for Figure 25 A cross-sectional view along the CC direction.

[0217] like Figures 24-26bAs shown, the mounting member 812 of the bracket 81 is fixedly connected to the base 41 of the first fixing member 4 in the rotating shaft mechanism 100 to mount the bracket 81 onto the rotating shaft mechanism 100. Specifically, in one embodiment, the base 41 is provided with a through hole 410 extending through the base 41 along the first direction X. The number of through holes 410 is not limited and can be one, two, three, etc., and can be set as needed. In one embodiment, the base 41 is provided with two through holes 410, which are respectively provided on both sides of the mounting part 42 in the second direction Y. Two connecting walls 8123 are provided between the mounting member 812 of the bracket 81 and the bracket body 811, and each connecting wall 8123 connects the bracket body 811 and the mounting member 812. The two connecting walls 8123 correspond to the two through holes 410 on the base 41, and each mounting component 812 is provided with a fixing hole 8120. Screws, bolts, or other fasteners can be passed sequentially through the through holes 410 on the base 41 and the fixing holes 8120 on the mounting component 812 to fix the bracket 81 to the first fixing component 4 of the rotating shaft mechanism 100. In other alternative embodiments, the base 41 and the bracket 81 can also be fixedly connected by bonding, welding, bolting, riveting, etc., and this application does not impose any limitations on this.

[0218] Those skilled in the art will understand that when the user rotates the bracket 81, torque will be generated between the bracket 81 and the rotating shaft mechanism 100. If only fasteners are used to connect the bracket 81 and the rotating shaft mechanism 100, frequent use of the bracket 81 may cause problems such as deformation of the bracket 81 and loosening of the fasteners. To enhance the reliability of the connection between the bracket 81 and the rotating shaft mechanism 100, some connection reinforcement structures can be provided between the bracket 81 and the rotating shaft mechanism 100. For example, a pin or other component can be provided between the mounting part 812 and the base 41 to reinforce the connection. The specific form is not limited.

[0219] like Figures 24-26b As shown, in one embodiment, a receiving groove is provided inside the mounting member 812, and part of the structure of the rotating shaft mechanism 100 is located inside the receiving groove. The reliability of the connection between the bracket 81 and the rotating shaft mechanism 100 is improved by increasing the connection area between them. It should be noted that this application does not limit the specific shape and position of the receiving groove on the mounting member 812, nor the structure in the rotating shaft mechanism 100 that mates with the receiving groove.

[0220] In one embodiment, the mounting member 812 includes a first receiving groove 8121, and the first fixing member 4 further includes a protrusion 44 connected to the base 41. The protrusion 44 protrudes from the base 41 in the first direction X toward the side opposite to the first damping structure 1. The protrusion 44 can be embedded in the first receiving groove 8121 to improve the connection strength between the mounting member 812 and the first fixing member 4. In one embodiment, the mounting member 812 also includes two second receiving grooves 8122. The two second receiving grooves 8122 are located on both sides of the first receiving groove 8121 in the second direction Y, and correspond to the two rotating arms 43 of the first fixing member 4 in the first direction X, respectively. The two rotating arms 43 can be respectively accommodated in the two second receiving grooves 8122. The specific form of the first receiving groove 8121 and the second receiving groove 8122 is not limited. For example, the first receiving groove 8121 can be formed by the space between two connecting walls 8123, and the second receiving groove 8122 can be formed by the space enclosed by each connecting wall 8123 and the side wall of the mounting member 812 on its side.

[0221] The shapes of the first receiving groove 8121 and the second receiving groove 8122 are not limited. In one embodiment, the protrusion 44 on the base 41 is a rectangular protrusion, and the first receiving groove 8121 is configured as a rectangular receiving groove corresponding to the shape of the protrusion 44. In one embodiment, the second receiving groove 8122 is an arc-shaped groove, and the rotating arm 43 on the base 41 is also configured as an arc, and the arc-shaped rotating arm 43 can be engaged in the arc-shaped second receiving groove 8122. In one embodiment, the end of the second fixing member 5 connected to each rotating arm 43 is also configured as an arc structure. When the bracket 81 is in the retracted state, the end of the second fixing member 5 can also be accommodated in the second receiving groove 8122. When the bracket 81 switches from the retracted state to the open state, the end of the second fixing member 5 can gradually disengage from the second receiving groove 8122. In other alternative embodiments, the shape of the first receiving groove 8121 may not be the same as that of the protrusion 44, and the shape of the second receiving groove 8122 may not be the same as that of the rotating arm 43. These will not be listed in detail in this application.

[0222] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
