Description

Rotating shaft mechanism and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 14, 2023, with application number: 202311191742.2 and application name: “Rotating shaft mechanism and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of rotating shafts, and in particular to a rotating shaft mechanism and electronic equipment. Background Art

[0003] Portable electronic devices such as foldable phones and tablets are large in size and not convenient to hold in hand for a long time. They often need to be placed on a desktop for use. In order to firmly support such electronic products on the desktop, they are usually equipped with a stand. Stands can be divided into external stands and built-in stands. External stands are external stands that are installed on electronic devices. They have various forms, such as metal stands, plastic stands, foldable stands, or the leather case of the electronic device is set to a foldable structure to be used as a stand, etc. The disadvantage of external stands is that they are not convenient to carry. When using, the stand needs to be assembled with the electronic device and then disassembled after use, which is not convenient. If an external device such as a leather case is installed on an electronic device for a long time, the electronic device will become too thick and heavy, and the user experience will be poor. In order to improve the portability of the stand, make it more convenient and quick for users to use the stand, and improve the user experience, some manufacturers set the stand directly on the housing of the electronic device when designing the electronic device, forming a stand that comes with the electronic device.

[0004] The built-in stand of an electronic device is generally connected to the electronic device body through a hinge mechanism, so that it can rotate relative to the electronic device body and switch between a stored state and an open state. When the stand is in the stored state, it fits the electronic device body, making it convenient to hold and carry the electronic device. When the stand is in the open state, it is opened to a certain angle relative to the electronic device body so as to support the electronic device on the desktop. The hinge mechanism includes a damping structure, which can generate a damping force so that the stand can hover at a certain angle when it rotates. The magnitude of the damping force of the damping structure directly determines the stability of the support of the electronic device on the desktop. However, in existing electronic devices with built-in stands, the damping force of the damping structure is related to its own length. Usually, the damping structure needs to be set longer to achieve stable support. The width of the stand corresponds to the length of the damping structure. When the length of the damping structure is longer, the width of the stand will also increase, resulting in a larger overall size of the stand.

[0005] For example, part of the rotating shaft mechanism includes a rotating shaft and a sleeve, and the rotating shaft is sleeved in the sleeve. The two rotate relative to each other. By connecting one of the electronic device body and the bracket to the sleeve and the other to the rotating shaft, the bracket can rotate around an axis relative to the electronic device body, and the axis direction is the same as the axial direction of the rotating shaft. When the rotating shaft and the sleeve rotate relative to each other, the friction between them generates a damping force. The larger the contact area between the two, the greater the damping force. In order to obtain sufficient damping force, the length of the rotating shaft and the sleeve can be increased along the axial direction, and the width of the bracket (the size of the bracket in the axial direction) is positively correlated with the length of the rotating shaft and the sleeve. When the length of the rotating shaft and the sleeve increases, the width of the bracket also needs to be increased. Alternatively, multiple pairs of mutually cooperating rotating shafts and sleeves can be set along the axial direction, and multiple pairs of rotating shafts and sleeves all provide damping force. In this case, the bracket needs to be connected to each pair of rotating shafts and sleeves. The more the number of rotating shafts and sleeves, the greater the width of the bracket. Therefore, in either case, the width of the bracket will be increased, resulting in a larger size of the bracket. The bracket occupies a larger area on the shell of the electronic device, which in turn causes problems such as large step differences in the appearance of the electronic device and low shell structural strength, and is not conducive to the lightweight design of the electronic device.

[0006] It can be seen that the rotating shaft mechanism in the electronic device with a built-in stand in the prior art cannot provide a large damping force when the stand width is small, and it is difficult to take into account both the stability of the stand support and the miniaturization design.

[0007] Summary of the Invention

[0008] The hinge mechanism and electronic device provided in the embodiments of the present application solve the problem in the prior art that the hinge mechanism in electronic devices with built-in brackets cannot provide a large damping force when the bracket width is small, and it is difficult to take into account both the stability of the bracket support and the miniaturized design.

[0009] An embodiment of the present application provides a rotating shaft mechanism for connecting a first component and a second component, wherein the first component is rotatably connected to the second component around a first axis, and the rotating shaft mechanism includes a first damping structure, a second damping structure and a connecting member, wherein the first damping structure is installed on the first component, and the first damping structure and the second damping structure are spaced apart in a first direction and connected by a connecting member.

[0010] When the first damping structure rotates around the first axis relative to the second component under the drive of the first component, the second damping structure is driven to rotate around the second axis relative to the second component through the connecting member. Both the first axis and the second axis extend along the second direction, and the second direction is perpendicular to the first direction.

[0011] The hinge mechanism provided in the embodiment of the present application can be used in electronic devices, where the first component can be a bracket, and the second component can be the electronic device body. The electronic device body and the bracket can be rotatably connected by the hinge mechanism, and the bracket can rotate relative to the electronic device body around a first axis. Two damping structures are provided in the hinge mechanism, and the two damping structures are linked by a connecting member. When the bracket and the electronic device body rotate relative to each other, the two damping structures both provide damping force, and the damping forces of each damping structure are superimposed together and can be used to support the electronic device body. The first damping structure and the second damping structure are arranged along a first direction, and the bracket rotates relative to the electronic device body around the first axis. The first axis extends along a second direction, and the first direction and the second direction are perpendicular to each other. It can be understood that the arrangement direction of the two damping structures is perpendicular to the axis direction of rotation of the bracket.

[0012] With this structure, the bracket is only installed on the first damping structure, and the width of the bracket (the size of the bracket in the second direction) is only related to the size of the first damping structure in the second direction. However, the supporting force of the bracket supporting the electronic device body is the superposition of the damping forces of the first damping structure and the second damping structure. 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 also be reduced accordingly. At the same time, the second damping structure can be designed to be larger in size to provide sufficient damping force to ensure the stability of the bracket when supporting the electronic device body.

[0013] It can be seen that the hinge mechanism provided in the embodiment of the present application 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 miniaturized design.

[0014] In some embodiments, the first damping structure includes a first rotating shaft and a first sleeve, the first rotating shaft is sleeved in the first sleeve, and can rotate around a third axis relative to the first sleeve; the second damping structure includes a second rotating shaft and a second sleeve, the second rotating shaft is sleeved in the second sleeve, and can rotate around a fourth axis relative to the second sleeve.

[0015] The first rotating shaft is installed on the first component, and the first sleeve is installed on the first component through the first rotating shaft; the first sleeve and the second sleeve are both connected to the connecting member and fixed relative to the connecting member to connect the first damping structure and the second damping structure through the connecting member.

[0016] The third axis and the fourth axis both extend along the second direction, and the first axis, the second axis, the third axis, and the fourth axis are spaced apart from each other; the distance between the first axis and the second axis is equal to the distance between the third axis and the fourth axis, and the distance between the first axis and the third axis is equal to the distance between the second axis and the fourth axis.

[0017] With the above solution, 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 linkage structure.

[0018] In some embodiments, a first limiting portion is provided within the first sleeve, and a portion of the outer surface of the first rotating shaft along its circumference is configured as a flat surface. The first limiting portion is an elastic structure. When the first rotating shaft rotates to a first position relative to the first sleeve, the first limiting portion and the first rotating shaft engage through a flat surface. A second limiting portion is provided within the second sleeve, and a portion of the outer surface of the second rotating shaft along its circumference is configured as a flat surface. The second limiting portion is an elastic structure. When the second rotating shaft rotates to a second position relative to the second sleeve, the second limiting portion and the second rotating shaft engage through a flat surface.

[0019] By adopting 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 changing feel and reminding the user to use the best angle of the bracket.

[0020] In some embodiments, the connecting member is configured as a connecting rod, with the first sleeve and the second sleeve formed at both ends of the connecting rod. That is, the first sleeve and the second sleeve are integrally formed with the connecting member, which is simple in structure and easy to process.

[0021] In some embodiments, the shaft mechanism further comprises:

[0022] The first fixing member is fixed to the first component. The first rotating shaft of the first damping structure is installed on the first fixing member. The first damping structure can be installed on the first component through the first fixing member.

[0023] The second fixing member is fixed to the second component. The second rotating shaft of the second damping structure is installed on the second fixing member. The second damping structure can be installed on the second component through the second fixing member.

[0024] The first fixing member can rotate relative to the second fixing member around the first axis, so that the first component can rotate relative to the second component around the first axis.

[0025] With this solution, the second fixing member is fixed to the electronic device body, and the bracket is fixed to the first fixing member. The bracket is rotatably connected to the second fixing member through the first 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.

[0026] In some embodiments, the first rotating shaft of the first damping structure is fixed to the first fixing member. With this structure, the first rotating shaft and the first fixing member do not rotate relative to each other, and the damping force of the first damping structure can be better transmitted to the bracket.

[0027] 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 drive 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.

[0028] In some embodiments, the second fixing member includes a base extending along the second direction, and two extending arms respectively connected to both ends of the base in the second direction, each of the two extending arms extends along the first direction and protrudes from the base toward the same side, so that an installation space is formed between the two extending arms and the base, and the first damping structure, the second damping structure, the connecting member and the first fixing member are all installed in the installation space. In the first direction, the second damping structure is located on the side of the first damping structure close to the base, and the first fixing member is located on the side of the first damping structure away from the base.

[0029] The first fixing member includes a base, a mounting portion, and two rotating arms, the base being fixedly connected to the first member, the mounting portion being connected to the base and protruding from the base in a first direction toward a side where the first damping structure is located, and the first rotating shaft of the first damping structure being mounted on the mounting portion;

[0030] The two rotating arms are respectively connected to the two ends of the base in the second direction, and the two rotating arms correspond 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 around the first axis relative to the second fixing member.

[0031] The first sliding structure includes an arcuate sliding groove and an arcuate sliding block which are slidably connected. One of the arcuate sliding groove and the arcuate sliding block of the first sliding structure is arranged on the rotating arm of the first fixing member, and the other is arranged on the extending arm of the second fixing member.

[0032] In some possible embodiments, the arc-shaped sliding groove of the first sliding structure is provided on the rotating arm of the first fixing member, and the arc-shaped sliding block is provided on the extending arm of the second fixing member.

[0033] In some embodiments, the mounting portion includes two bosses spaced apart in the second direction, the first damping structure is located between the two bosses, and each of the two bosses is provided with a through hole. The ends of the first rotating shaft in the first damping structure protrude from the first sleeve and are respectively inserted into the through holes of the two bosses. With this structure, the first fixing member can drive the first rotating shaft to move, thereby enabling the first damping structure to rotate relative to the second component.

[0034] In some possible embodiments, both ends of the first rotating shaft are fixedly connected to the two bosses, so that the first rotating shaft is fixed to the first fixing member.

[0035] In some embodiments, the first fixing member further includes a protrusion connected to the base. The protrusion protrudes from the base in the first direction toward a side away from the first damping structure and is embedded in the first component.

[0036] By adopting the above solution, the connection strength between the mounting member and the first fixing member can be improved.

[0037] In some embodiments, the second damping structure also includes two bushings spaced apart along the second direction, and the two bushings are respectively sleeved on both ends of the second rotating shaft; the two bushings correspond one-to-one to the two extension arms of the second fixing member, and each of the two bushings is slidably connected to the corresponding extension arm through a second sliding structure, so that the second damping structure can rotate around the second axis relative to the second fixing member.

[0038] The second sliding structure includes an arcuate sliding block and an arcuate sliding groove which are slidably connected to each other. One of the arcuate sliding block and the arcuate sliding groove of the second sliding structure is arranged on the shaft sleeve, and the other is arranged on the extension arm of the second fixing member.

[0039] In some possible embodiments, the arc-shaped sliding block of the second sliding structure is disposed on the shaft sleeve, and the arc-shaped sliding groove is disposed on the extension arm of the second fixing member.

[0040] In some embodiments, the second fixing member has two fixing parts, each of the two fixing parts includes a first part extending along the second direction and a second part extending along the first direction, the first part and the second part are connected, the first parts of the two fixing parts are connected and fixedly connected to form a base body of the second fixing member, and the second part of each of the two fixing parts respectively constitutes two extension arms of the second fixing member.

[0041] With the above solution, the second fixing member adopts a split structure, and the second fixing member is split into two fixing parts, each fixing part includes an extension arm and a part of the seat body, which is convenient for assembling the rotating shaft mechanism.

[0042] An embodiment of the present application further provides an electronic device, comprising an electronic device body and a bracket, and further comprising the hinge mechanism provided in any of the above embodiments, wherein 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 that the electronic device body and the bracket are rotatably connected via the hinge mechanism. The electronic device utilizes the hinge mechanism provided in the present application, and the bracket has a small width, and the bracket occupies a small area on the housing of the electronic device. The electronic device has a small step difference in appearance and a high structural strength, which is conducive to the lightweight and thin design of the electronic device.

[0043] 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 middle frame, and a back cover. The middle frame includes a bottom plate and an outer frame. The display screen and the back cover are respectively mounted on opposite ends of the outer frame in a third direction, and the bottom plate is located between the display screen and the back cover. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0044] A hollow portion is provided on the back cover of the electronic device body, and the hinge mechanism and the bracket are arranged on the bottom plate of the middle frame along the first direction. In addition, in the third direction, the bracket and the hinge mechanism are correspondingly arranged in the hollow portion of the back cover.

[0045] The bracket includes a bracket body and a mounting member. The bracket body is configured as a plate-like structure. The mounting member is connected to the bracket body and is located on a side of the bracket body facing the display screen in the third direction. A hinge mechanism is mounted on the bracket mounting member, enabling the bracket to rotate about a first axis relative to the electronic device body to switch between a stowed state and an open state. When the bracket is in the stowed state, the bracket body is entirely embedded in a hollow portion of the rear cover. When the bracket is in the open state, at least a portion of the bracket body is separated from the hollow portion and protrudes from the outer surface of the electronic device body.

[0046] With the above solution, when the bracket is in the stored state, the bracket body can be embedded in the electronic device body without protruding from the electronic device body. The bracket does not increase the local thickness of the electronic device, making the electronic device thinner.

[0047] In some embodiments, the electronic device body also includes a cover plate, which is arranged in the hollow portion of the back cover. The cover plate is arranged on the side of the bracket facing the hinge mechanism along the first direction 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 stored state, the projection of the bracket structure along the third direction on the display screen coincides with the projection of the hollow portion along the third direction on the display screen.

[0048] The bottom plate of the middle frame is provided with a stepped structure, which connects to the bottom plate and is located on the side of the bottom plate facing away from the display in the third direction. The stepped structure comprises a top surface and side surfaces that are perpendicular to each other. The side surfaces extend along the third direction, and the top surface connects to the side surfaces at the end facing away from the display in the third direction. When the stand is in the stowed position, the top surface faces the stand body. When the stand is in the open position, an opening is formed between the stand body and the top surface of the stepped structure.

[0049] With the above solution, the step structure has a certain thickness. When the bracket body is rotated open, the top surface of the step structure can cover the opening between the bracket body and the electronic device body, allowing the user to see the top surface of the step structure instead of other electronic components in the electronic device, thereby improving the electronic aesthetics while protecting the electronic components of the electronic device.

[0050] In some embodiments, the first axis is located on a surface of the support structure away from the display screen in the third direction, and is located at a joint between the cover plate and the support body.

[0051] 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 always fit together through the gap, and the electronic device has a simple and beautiful appearance and a smooth plane transition.

[0052] In some embodiments, the mounting member of the bracket is configured as an arc-shaped structure, a receiving groove is provided in the mounting member, and part of the structure of the rotating shaft mechanism is located in the receiving groove. When the bracket is in the storage state, the mounting member as a whole is located on the side of the step structure facing the cover plate in the first direction. When the bracket is in the open state, at least part of the structure of the mounting member is located on the side of the step structure facing away from the cover plate in the first direction.

[0053] With the above solution, the arc-shaped mounting part is located in the gap between the step structure and the rotating shaft mechanism. When the bracket rotates, the arc-shaped structure also rotates in the gap. When the bracket body is opened to a certain angle relative to the electronic device body, the arc-shaped structure is also exposed to the outside together with the bracket body, covering the gap between the step structure and the rotating shaft mechanism, and also covering the gap between the bracket body and the rotating shaft mechanism, thereby providing all-round shielding for the rotating shaft mechanism.

[0054] In some possible embodiments, the accommodating groove of the mounting member includes a first accommodating groove and two second accommodating grooves, each of the first accommodating groove and the two second accommodating grooves is spaced apart along the second direction, and the first accommodating groove is located between the two second accommodating grooves.

[0055] When the rotating shaft mechanism includes a first fixing member, and the first fixing member includes two rotating arms and a protrusion, at least part of the structure of the protrusion is located in the first accommodating groove, the two rotating arms correspond one-to-one to the two second accommodating grooves, and at least part of the structure of each rotating arm is located in the corresponding second accommodating groove.

[0056] 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0135] Portable electronic devices such as foldable phones and tablets are large in size and not convenient to hold in hand for a long time. They often need to be placed on a desktop for use. In order to firmly support such electronic products on the desktop, they are usually equipped with a stand. Stands can be divided into external stands and built-in stands. External stands are external stands that are installed on electronic devices. They have various forms, such as metal stands, plastic stands, foldable stands, or the leather case of the electronic device is set to a foldable structure to be used as a stand, etc. The disadvantage of external stands is that they are not convenient to carry. When using, the stand needs to be assembled with the electronic device and then disassembled after use, which is not convenient. If an external device such as a leather case is installed on an electronic device for a long time, the electronic device will become too thick and heavy, and the user experience will be poor. In order to improve the portability of the stand, make it more convenient and quick for users to use the stand, and improve the user experience, some manufacturers set the stand directly on the housing of the electronic device when designing the electronic device, forming a stand that comes with the electronic device.

[0136] The built-in stand of an electronic device is generally connected to the electronic device body via a hinge mechanism, allowing it to rotate relative to the electronic device body and switch between a stowed state and an open state. When the stand is in the stowed state, it fits snugly against the electronic device body, making it convenient to hold and carry the electronic device. When the stand is in the open state, it is opened to a certain angle relative to the electronic device body to support the electronic device body on a desktop. The hinge mechanism includes a damping structure that generates a damping force, allowing the stand to hover at a certain angle during rotation. The magnitude of the damping force of the damping structure directly determines the stability of the electronic device supported on the desktop. However, in existing electronic devices with built-in stands, the damping force of the damping structure is related to its own length, and the damping structure usually needs to be longer to achieve stable support. The width of the stand corresponds to the length of the damping structure. If the damping structure is longer, the width of the stand will also increase, resulting in a larger overall size of the stand. The following illustrates this issue by combining the structures of several electronic devices with built-in stands and their hinge mechanisms.

[0137] Please refer to FIG1 , which is a schematic structural diagram of an electronic device.

[0138] As shown in Figure 1, 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 hinge mechanism 3' and can rotate relative to the electronic device 100'. Specifically, the hinge mechanism 3' includes a damping structure 31', which can be composed of a shaft 311' and a sleeve 312'. The shaft 311' is sleeved within 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 shaft 311', the bracket 2' can rotate relative to the electronic device body 1' about a first axis Q'. In the scenario illustrated in Figure 1, the bracket 2' is fixedly connected to the shaft 311' via a connector 4', and the sleeve 312' is fixedly connected to the electronic device body 1'. The axis direction Y' (the direction of the first axis Q') is the same as the axial direction of the shaft 311', or it can be understood that the axis center of the shaft 311' is the first axis Q'.

[0139] When the rotating shaft 311' and the sleeve 312' rotate relative to each other, friction between them generates a damping force, which can be used as a force to support the electronic device body 1'. The larger the contact area between the rotating shaft 311' and the sleeve 312', the greater the damping force, and the more securely the bracket 2' supports the electronic device 100'. However, the rotating shaft 311' rotates relative to the sleeve 312' driven by the bracket 2'. To improve the stability of the rotating shaft 311''s rotation and prevent it from getting stuck, it is necessary to ensure that the force on the rotating shaft 311' is evenly distributed. Generally, both ends of the rotating shaft 311' are connected to the bracket. For example, in Figure 1, each end of the rotating shaft 311' is fixedly connected to the opposite end of the bracket 2' via a connecting member 4'. In this case, the width d' of the bracket 2' (the dimension of the bracket 2' in the axial direction Y') is positively correlated with 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. In order to stably support the electronic device body 1' and obtain sufficient damping force, the length of the shaft 311' and the sleeve 312' can be increased along the axis direction Y' to increase the contact area between the shaft 311' and the sleeve 312'. In this way, the width d' of the bracket 2' is also longer.

[0140] Please refer to FIG2 , which is a schematic structural diagram of another electronic device.

[0141] As shown in Figure 2, 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 hinge mechanism 3", and can rotate relative to the electronic device 100". Unlike the electronic device 100' shown in Figure 1, the hinge mechanism 3" of the electronic device 100" includes multiple damping structures 31" (4 are shown in the figure) arranged along the axial direction Y". Each damping structure 31" includes a pair of mutually cooperating rotating shafts 311" and sleeves 312". The bracket 2" can be connected to the rotating shaft 311" of each damping structure 31" through a connecting member 4". When the bracket 2" rotates, it drives each rotating shaft 311" to rotate relative to the corresponding sleeve 312". The friction force generated by the mutual friction between the rotating shaft 311" and the sleeve 312" in each damping structure 31" is superimposed to form the damping force of the hinge 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 of the first axis Q″), and the bracket 2″ needs to be connected to the rotating shaft 311″ in each damping structure 31″. The more damping structures 31″ there are, the larger the width d″ of the bracket 2″. To ensure stable support for the electronic device body 1″ and sufficient damping force, it is necessary to increase the number of damping structures 31″ and the width d″ of the bracket 2″ will also be larger.

[0142] From the above two structures, it can be seen that the hinge mechanism in the electronic device with its own stand cannot provide a large damping force when the stand width is small, and it is difficult to take into account both the stability of the stand support and the miniaturization design.

[0143] It will be understood by those skilled in the art that the bracket is usually installed on the housing of the electronic device. If the width of the bracket is large, its overall size is large, and it occupies a large area on the housing of the electronic device, which in turn causes a large step difference in the appearance of the electronic device. Since the bracket and the housing of the electronic device are separable structures, the position on the housing for accommodating the bracket usually needs to be grooved, the thickness of the housing at this location is reduced, and the structural strength of the housing is reduced. On the other hand, in order to ensure the flatness of the appearance of the electronic device, the bracket is generally of embedded design, and is embedded as a whole in the electronic device body when in the storage state. When the thickness of the electronic device is certain, the electronic components inside the electronic device body corresponding to the position of the bracket need to be avoided. The large size of the bracket is not conducive to the spatial layout of the electronic components, resulting in problems such as some electronic components cannot be installed. In order to avoid such problems, the thickness of the electronic device can only be increased to increase the accommodating space for electronic components. Therefore, the large size of the bracket is also not conducive to the lightweight design of the electronic device.

[0144] In order to solve the above problems, the present application provides a rotating shaft mechanism, in which the damping structure is arranged perpendicular to the axial direction, which can provide a larger damping force when the width of the electronic device bracket is small, and can take into account the stability of the bracket support and the miniaturized design.

[0145] An embodiment of the present application also provides an electronic device, which utilizes the hinge mechanism provided by the present application. The bracket width is small, the bracket occupies a small area on the housing of the electronic device, the appearance step difference of the electronic device is small, and the structural strength is high, which is conducive to the lightweight design of the electronic device.

[0146] The electronic devices provided in this application may be, but are not limited to, mobile phones, tablet computers, monitors, personal digital devices, smart wearable devices, etc. The mobile phone may be an all-in-one mobile phone or a foldable screen mobile phone. The following uses a foldable screen mobile phone as an example to illustrate the structure of the electronic device. It should be noted that the following description of the structure of the electronic device is only an example and does not limit the electronic device provided in this application. In fact, the electronic device may include more or fewer components as shown in the following examples and drawings.

[0147] Please refer to Figures 3a-6. Figures 3a-3b are schematic diagrams of the three-dimensional structure of the electronic device of the embodiment of the present application from different perspectives, wherein the electronic device body is in an unfolded state; Figure 4 is a schematic diagram of the three-dimensional structure of the electronic device of the embodiment of the present application, wherein the electronic device body is in a folded state; Figure 5 is a back view of the electronic device of the embodiment of the present application, wherein the electronic device body is in an unfolded state; Figure 6 is a back view of the electronic device of the embodiment of the present application without the cover.

[0148] As shown in Figures 3a to 6, the electronic device 200 includes an electronic device body 7 and a bracket 81, and the bracket 81 is used to support the electronic device body 7. It will be understood by those skilled in the art 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 shell assembly 72, and the display screen 71 is mounted on the shell assembly 72. The display screen 71 is used to display images and human-computer interaction, and the shell assembly 72 is used to support the display screen 71, which has an accommodation space inside, which can be said to accommodate the installation of other electronic components. Among them, electronic components include but are not limited to circuit boards, batteries, camera modules, microphones, speakers, etc., and this application does not limit this.

[0149] 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 spaces for accommodating 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 the unfolded state shown in Figures 3a-3b, Figures 5-6, and the folded state shown in Figure 4.

[0150] In one embodiment, when the electronic device body 7 is in the expanded state, the angle at which it is opened is 180°, that is, the angle between the first shell 721 and the second shell 722 is 180°. It will be understood by those skilled in the art that the opening angle of the electronic device body 7 may also be 90°, 120°, 210°, etc., and this application does not limit this. In addition, the angles illustrated in this application are all allowed to have slight deviations. For example, when the electronic device body 7 is in the expanded state, the angle at which the first shell 721 and the second shell 722 are opened may be 180°, or approximately 180°, such as 170°, 175°, 185° or 190°, etc., and the same understanding may be given to other angles hereinafter.

[0151] Furthermore, the first shell 721 and the second shell 722 can both rotate about the hinge device 723, allowing the first shell 721 and the second shell 722 to rotate relative to each other. When the first shell 721 and the second shell 722 are rotated relative to each other until they are coplanar, the electronic device body 7 is in an unfolded state, at which point the angle between the first shell 721 and the second shell 722 is 180°. When the first shell 721 and the second shell 722 are rotated relative to each other until they overlap each other, the electronic device body 7 is in a folded state, at which point the angle between the first shell 721 and the second shell 722 can be approximately considered to be 0°.

[0152] It should be noted that this application does not limit the structure of the display screen 71 and the connection method between the display screen 71 and the housing assembly 72.

[0153] As shown in Figures 3a-4, in one embodiment, a display screen 71 is provided on one side of a housing assembly 72. Display screen 71 may be, but is not limited to, an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, or a quantum dot light-emitting diode (QLED) display. Display screen 71 is connected to a side surface of housing assembly 72. The side of display screen 71 facing away from housing assembly 72 serves as a display surface, which is used to display information and provide an interactive interface for the user.

[0154] 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 the first housing 721, the second portion 712 is connected to the second housing 722, and the foldable portion 713 is located between the first portion 711 and the second portion 712. During use of the foldable electronic device body 7, the first portion 711 and the second portion 712 always remain in a planar state, while the foldable portion 713 can bend 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. Exemplarily, in the display screen 71, at least a portion of the foldable portion 713 is made of a flexible material so that the foldable portion 713 is bendable.

[0155] Driven by the hinge device 723, the display screen 71 opens or closes together with the first shell 721 and the second shell 722. The foldable portion 713 of the display screen 71 is flattened or bent to allow 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 a relatively distant expanded state, 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 relatively stacked, the foldable portion 713 is in a bent state, and the display surfaces of the first portion 711 and the second portion 712 face each other or opposite each other.

[0156] 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 the folded state, the display screen 71 surrounds the outer side of the housing assembly 72. Alternatively, it can be understood that the first portion 711 and the second portion 712 of the display screen 71 are arranged opposite each other, the housing assembly 72 is located between the first portion 711 and the second portion 712, and the display surfaces of the first portion 711 and the second portion 712 are exposed to the user. When the electronic device body 7 of the inward-folding electronic device is in the folded state, the first portion 711 and the second portion 712 of the display screen 71 face each other, the display screen 71 is entirely contained within the housing assembly 72, and the housing assembly 72 protects the display screen 71.

[0157] Furthermore, the bracket 81 is mounted on the shell assembly 72 and is located on the back side of the shell assembly 72 (the side of the shell 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, the electronic device body 7 is large in size and is not convenient for holding for a long time. It can be supported by the bracket 81 for use on a desktop. It should be noted that the specific position of the bracket 81 on the shell assembly 72 is not limited. It can be mounted on the first shell 721, the second shell 722, or both the first shell 721 and the second shell 722. As shown in Figure 3b, Figure 5-Figure 6, in one embodiment, the bracket 81 is mounted on the first shell 721.

[0158] Those skilled in the art will appreciate that the installation position of the bracket 81 on the first shell 721 and the matching relationship between the bracket 81 and the first shell 721 are not limited. The following exemplifies the possible structures with reference to the accompanying drawings.

[0159] Please refer to Figures 7-10c, Figure 7 is a partial enlarged view of part D in Figure 3b; Figure 8 is a schematic diagram of the matching relationship between the bracket and the shell in the electronic device of the embodiment of the present application, wherein the bracket is in an open state; Figure 9a is a schematic diagram of the cross-sectional structure of the electronic device of the embodiment of the present application, wherein the bracket is in a stored state; Figure 9b is a schematic diagram of the cross-sectional structure of the electronic device of the embodiment of the present application, wherein the bracket is in an open state; Figure 10a is a schematic diagram of the matching relationship between the bracket, the rotating shaft mechanism and the step structure in the electronic device of the embodiment of the present application, wherein the bracket is in a stored state; Figures 10b-10c are schematic diagrams of the matching relationship between the bracket, the rotating shaft mechanism and the step structure in the electronic device of the embodiment of the present application, wherein the bracket is in an open state, and the opening angles of the bracket in Figures 10b and 10c are different.

[0160] It should be noted that FIG. 9 a and FIG. 9 b are schematic diagrams, which are only used to illustrate the coordination relationship between the rotating shaft mechanism 100 and the bracket 81 and other components in the electronic device 200 , and cannot limit the specific structure of the electronic device 200 .

[0161] As shown in Figures 3a-10c, the electronic device 200 further includes a hinge mechanism 100. The electronic device body 7 and the bracket 81 are rotatably connected via the hinge mechanism 100. The bracket 81 can rotate relative to the electronic device body 7 about a first axis Q1 to switch between a stowed state and an open state. The first axis Q1 is oriented in the 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.

[0162] In one embodiment, the hinge mechanism 100 and the bracket 81 are arranged along a first direction X, and the first direction X is perpendicular to the second direction Y. Alternatively, it can be understood that the hinge mechanism 100 and the bracket 81 are arranged in a direction perpendicular to the axis of rotation of the electronic device. It will be understood by those skilled in the art that the arrangement direction 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, the first direction X and the second direction Y can both be inclined to the length direction of the electronic device 200, that is, the bracket 81 is arranged obliquely 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 perpendicular to each other.

[0163] Exemplarily, when the bracket 81 is in the retracted state, the bracket 81 fits the electronic device body 7 as a whole, 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 inconsistent with the thickness direction of the electronic device body 7. Among them, the relative opening angle between the bracket 81 and the electronic device body 7 is not limited, and can be a specific angle or an arbitrary angle. For example, the design of the damping structure in the hinge mechanism 100 can enable the bracket 81 to hover at any angle within its allowed range of travel, and can support the electronic device body 7 at any angle. Alternatively, some limiting structures can be set to limit the rotation travel of the bracket 81, and cooperate with the design of the damping structure to enable the bracket 81 to only hover at one or more set angles to support the electronic device body 7.

[0164] 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 is rotated to a specific angle relative to the electronic device body 7 (which can be designed based on the actual product size, for example, 60°, 75°, 80°, etc., without limitation), the angle between the bracket 81 and the electronic device 200 reaches its maximum, and at this time, the electronic device 200 is placed on the desktop for optimal use. In one embodiment, multiple limiting structures can be provided between the bracket 81 and the electronic device body 7, each limiting structure corresponding to a specific angle. When the bracket 81 rotates to several specific angles, the damping force of the hinge mechanism 100 is relatively large, and the electronic device 200 can be placed on the desktop at any of the specific angles, meeting different usage requirements. In one embodiment, a limiting structure is provided between the bracket 81 and the electronic device body 7, and the limiting structure corresponds to a specific angle. The bracket 81 can hover at any angle within its travel range and support the electronic device body 7. The bracket 81 is most effective in supporting the electronic device body 7 when it hovers at a specific angle.

[0165] Those skilled in the art will appreciate that the structure of the first housing 721 is not limited. The following, in conjunction with the accompanying drawings, illustrates exemplary structures of the first housing 721 and the coordination between the bracket 81, the hinge 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 embodiment, the following description will only focus on the structure of the first housing 721, and will not expand on the structure of the second housing 722. The second housing 722 may have the same or different structure as the first housing 721, and this is not a limitation of this disclosure.

[0166] As shown in Figures 9a to 10c, in one embodiment, the first shell 721 includes a middle frame 724 and a back cover 725, the middle frame 724 includes a bottom plate 7242 and an outer frame 7241, the display screen 71 and the back cover 725 are respectively installed on both sides of the outer frame 7241 in the third direction Z (i.e., the upper and lower sides in Figures 9a and 9b), and the bottom plate 7242 is located between the display screen 71 and the back cover 725.

[0167] The back cover 725 of the electronic device body 7 has a hollow portion 7250. The hinge mechanism 100 and the bracket 81 are disposed on the bottom plate 7242 of the middle frame 724 and are disposed within the hollow 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 hollowed out to accommodate the bracket 81 and the hinge mechanism 100 mounted on the bottom plate 7242 of the middle frame 724.

[0168] 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. The mounting member 812 is connected to the bracket body 811 and is located on the side of the bracket body 811 facing the display screen 71 in the third direction Z. The hinge mechanism 100 is installed on the mounting member 812 of the bracket 81. Among them, the bracket body 811 is a structure for supporting the electronic device body 7, and the mounting member 812 is mainly used to connect with the hinge mechanism 100. In the third direction Z, the hinge mechanism 100 and the mounting member 812 are both located on the side of the bracket body 811 facing the display screen 71. With such a structure, there is a height difference between the bracket body 811 and the hinge mechanism 100, which makes it easy to hide the hinge mechanism 100 in the electronic device body 7. In one embodiment, when the bracket 81 is in the stowed state, the bracket body 811 is entirely embedded in the hollow portion 7250 of the back cover 725, or it can be understood that in the third direction Z, the bracket body 811 is entirely located within the hollow portion 7250. When the bracket 81 is in the open state, at least part of the bracket body 811 is separated from the hollow portion 7250 and protrudes from the outer surface of the electronic device body 7, that is, the bracket body 811 is relatively open to the electronic device body 7. With this structure, when the bracket 81 is in the stowed state, the bracket body 811 can be embedded in the electronic device body 7 without protruding from the electronic device body 7. The bracket 81 does not increase the local thickness of the electronic device 200, making the electronic device 200 lighter and thinner.

[0169] As shown in FIG9a , in one embodiment, when the bracket 81 is in a closed state, in the first direction X, the bracket 81 is located between the two outer frames 7241 of the middle frame 724, and the end of the bracket 81 away from the first axis Q1 is in a clearance fit with the outer frame 7241 on that side (the right side in FIG9a ). In other alternative embodiments, the bracket 81 may also extend onto the outer frames 7241, for example, by hollowing out a portion of the right outer frame 7241 in FIG9a to accommodate the bracket 81, and this application is not limited thereto.

[0170] As shown in Figures 9a-10c, in one embodiment, the electronic device body 7 further includes a cover plate 82 disposed within the hollow 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 hinge mechanism 100 and is connected to the bracket body 811, such that the cover plate 82 and the bracket 81 form a bracket structure 8. When the bracket 81 is in the stowed state, the projection of the bracket structure 8 along the third direction Z onto the display screen 71 coincides with the projection of the hollow portion 7250 along the third direction Z onto the display screen 71. Alternatively, it can be understood that the cover plate 82 is disposed above the hinge mechanism 100, concealing the hinge mechanism 100 within the electronic device body 7, preventing the user from directly viewing the hinge mechanism 100 from the outside. Furthermore, the support structure 8 consisting of the cover plate 82 and the bracket 81 is connected and laid in the hollow portion 7250 of the back cover 725. When the bracket 81 is in the storage 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 physical structure of the back 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. It can be understood by those skilled in the art that the cover plate 82 is to shield and protect the hinge mechanism 100. The cover plate 82 can be provided separately or integrally formed with the back cover 725. This is not limited in this application. In an example scenario, when the cover plate 82 is integrally formed with the back cover 725, a part of the structure of the back cover 725 can be reused as the cover plate, and the hollow portion 7250 of the back cover 725 can be used only to accommodate the bracket 81.

[0171] In one embodiment, in the third direction Z, the surface of the cover plate 82 away from the display screen 71 and the surface of the back cover 725 away from the display screen 71 are located in the same plane. When the bracket 81 is in the storage state, the surface of the bracket 81 away from the display screen 71 and the surface of the back cover 725 away from the display screen 71 are also located in the same plane. Or it can be understood that, in the perspective of Figures 9a to 10c, when the bracket 81 is in the storage state, the upper surface of the bracket body 811 is flush with the upper surface of the back cover 725, which can ensure the flatness and smoothness of the outer surface of the electronic device 200, so that the thickness of the electronic device 200 is relatively uniform, simple and beautiful, and has a good feel when used. 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 impose any restrictions on this.

[0172] It should be noted that, in order to make the electronic device beautiful, the shapes of the bracket 81 and the cover 82 can be designed so that the back cover 725 of the electronic device presents a specific shape. The bracket 81 and the cover 82 can be matched through a gap, or can be connected and matched through all other styling parts, and this application does not impose any restrictions on this. For example, as shown in Figure 7, in one embodiment, a crossbeam 726 is provided between the bracket 81 and the cover 82, so that the bracket 81, the cover 82 and the crossbeam 726 present an H-shaped structure with a simple and beautiful shape. Among them, the crossbeam 726 can be integrally formed with the back cover 725, or it can be a split structure, and this application does not impose any restrictions on this. In other alternative embodiments, the crossbeam 726 may not be provided between the bracket 81 and the cover 82, and the bracket 81 and the cover 82 may also be designed into other shapes, which can be set as needed.

[0173] Those skilled in the art will appreciate that when the bracket 81 is in the stowed state, the bracket 81 and the cover plate 82 together seal the hollow portion 7250 on the back cover 725. However, when the bracket 81 is in the open state, an opening is created between the bracket body 811 and the electronic device body 7, exposing the hollow portion 7250 on the back cover 725 and the internal structure of the electronic device 200. To address this issue, some shielding structure can be provided in the electronic device body 7.

[0174] As shown in Figures 8-10c, in one embodiment, a step structure 9 is provided on the bottom plate 7242 of the middle frame 724. The step structure 9 is connected to the bottom plate 7242 and is located on the side of the bottom plate 7242 facing away from the display screen 71 in the third direction Z. The bracket 81 is disposed on the bottom plate 7242 of the middle frame 724 via the step structure 9. The step structure 9 includes a top surface 91 and a side surface 92 that are perpendicular to each other. The side surface 92 extends along the third direction Z, and the top surface 91 is connected to the end of the side surface 92 that is away from the display screen 71 in the third direction Z. When the bracket 81 is in the stowed 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 step structure 9. Or it can be understood that the step structure 9 is arranged between the bracket body 811 and the bottom plate 7242 of the middle frame 724, and 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, thereby improving the electronic aesthetics while protecting the electronic components of the electronic device 200.

[0175] It should be noted that the present application does not limit the specific structure of the step structure 9, which may be a straight plate structure, an "L-shaped" plate structure, etc. The step structure 9 may be integrally formed with the bottom plate 7242 of the middle frame 724, or a split design may be adopted, with the step structure 9 mounted on the bottom plate 7242, and this application does not limit this.

[0176] Furthermore, since the bracket 81 is connected to the shaft structure 100, the connection position between the bracket 81 and the shaft mechanism 100 is connected and transitioned by a connecting piece or other structure, and this position cannot be shielded by the step structure 9. When the bracket 81 is opened, the connection position between the shaft mechanism 100 and the bracket 81 will still be exposed. The shape design of the mounting piece 812 on the bracket 81 can shield the shaft mechanism 100.

[0177] As shown in FIG8-10 c , 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 stowed state, the mounting member 812 is entirely located on the side 92 of the step structure 9 facing the cover 82 in the first direction X. When the bracket 81 is in the open state, at least a portion of the mounting member 812 is located on the side 92 of the step structure 9 facing away from the cover 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 step structure 9 and the hinge mechanism 100. When the bracket 81 rotates, the arc-shaped structure also rotates within the gap. When the bracket body 811 is opened to a certain angle relative to the electronic device body 7, the arc-shaped structure is exposed along with the bracket body 811, shielding the gap between the step structure 9 and the hinge mechanism 100, and also shielding the gap between the bracket body 811 and the hinge mechanism 100, thereby providing all-round shielding for the hinge mechanism 100.

[0178] Those skilled in the art will appreciate that the bracket 81 rotates relative to the electronic device body 7 around the first axis Q1 , and the position of the first axis Q1 is not limited.

[0179] As shown in Figures 3a to 10c, in one embodiment, the first axis Q1 is located on the surface of the support structure 8 away from the display screen 71 in the third direction Z, and is located at the joint between the cover plate 82 and the support body 811. During the rotation of the support 81 relative to the electronic device body 7, the upper surface of the support body 811 and the upper surface of the cover plate 82 are always matched through the gap, and the electronic device 200 has a simple and beautiful appearance and a smooth plane transition. In other alternative embodiments, the first axis Q1 can also be located outside the surface of the support structure 8, or outside the joint between the cover plate 82 and the support body 811, etc., and this application does not impose any restrictions on this.

[0180] The foregoing mainly describes the structure of the electronic device 200 to roughly illustrate the matching relationship between the bracket 81 and the electronic device body 7, as well as the usage scenario of the hinge mechanism 100 provided in this application. The following further illustrates the principle and structure of the hinge mechanism 100 in conjunction with the accompanying drawings.

[0181] Please refer to Figures 11 and 12, which are schematic diagrams of the principle structure of the rotating shaft mechanism of the embodiment of the present application.

[0182] As shown in Figures 11 and 12, the hinge mechanism 100 provided in the embodiment of the present application can be used to connect the first component E and the second component F, and the first component E can rotate relative to the second component F around the 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 through the hinge 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, and 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, and this will not be repeated.

[0183] The hinge 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 and second damping structures 1 and 2 are spaced apart in a first direction X and connected by the connecting member 3. The first damping structure 1 can rotate relative to the second component F about a first axis Q1 driven by the first component E. The second damping structure 2 can also rotate relative to the second component F about a second axis Q2 driven by the connecting member 3. Both the first and second axes Q1 and Q2 extend along the second direction Y.

[0184] The hinge mechanism 100 provided in the embodiment of the present 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 a damping force. The damping forces of each damping structure are combined to support the second component F, such as the bracket 81 supporting the electronic device body 7. The first damping structure 1 and the second damping structure 2 are arranged along a first direction X, while the bracket 81 rotates relative to the electronic device body 7 about a first axis Q1. The first axis Q1 extends along a 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.

[0185] With this structure, the bracket 81 is only installed on the first damping structure 1, and the width of the bracket 81 (the size of the bracket 81 in the second direction Y) is only related to the size of the first damping structure 1 in the second direction Y. However, the supporting force of the bracket 81 supporting the electronic device body 7 is the superposition 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 size 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 in size to provide sufficient damping force to ensure the stability of the bracket 81 when supporting the electronic device body 7.

[0186] It can be seen that the hinge mechanism 100 provided in the embodiment of the present application can provide a larger 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.

[0187] Those skilled in the art will appreciate that the specific structures of the first damping structure 1 , the second damping structure 2 and the connecting member 3 are not limited, and possible structures thereof are described below with reference to the accompanying drawings.

[0188] Please refer to Figures 13-18b, Figure 13 is a schematic diagram of the three-dimensional structure of the rotating shaft mechanism of the embodiment of the present application; Figure 14 is a schematic diagram of the top structure of the rotating shaft mechanism of the embodiment of the present application; Figure 15 is a schematic diagram of the cross-sectional structure along the AA direction in Figure 14; Figure 16 is a schematic diagram of the cross-sectional structure of the rotating shaft mechanism of the embodiment of the present application along the AA direction in Figure 14 in another state; Figure 17 is a schematic diagram of the decomposed structure of the rotating shaft mechanism of the embodiment of the present application; Figure 18a 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 the embodiment of the present application; Figure 18b 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 the embodiment of the present application at another angle.

[0189] As shown in Figures 11-18b, 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 within 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 within the second sleeve 22 and can rotate relative to the second sleeve 22 about a fourth axis Q4. The third axis Q3 and the fourth axis Q4 both extend along the second direction Y. The first sleeve 12 and the second sleeve 22 are both connected to the connecting member 3 and fixed relative to the connecting member 3, thereby connecting the first damping structure 1 and the second damping structure 2 via the connecting member 3.

[0190] The first rotating shaft 11 is mounted on the first component E, that is, the bracket 81 of the electronic device 200 is connected to the first rotating shaft 11 and is mounted on the electronic device 200 via the first rotating shaft 11. When the bracket 81 is needed, the user can manually rotate the bracket 81, and 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 the damping force of the first damping structure 1. At the same time, the first rotating shaft 11 and the first sleeve 12 rotate about the first axis Q1, driving the second rotating shaft 21 and the second sleeve 22 to rotate about the second rotating shaft 21. The second rotating shaft 21 rotates relative to the second sleeve 22 within the second sleeve 22. The friction between the two generates the damping force of the second damping structure 2. The first sleeve 12 and the second sleeve 22 are both connected to the connecting member 3 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.

[0191] Among them, the first axis Q1 is the axis of rotation of the first damping structure 1 relative to the second component F, and is 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 or may not coincide, and this application does not impose any restrictions on this. 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 center 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 center 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 connecting member 3, the third axis Q3 and the fourth axis Q4 are also parallel to each other and both extend along the second direction Y.

[0192] 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, within 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 this parallelogram structure, the edge between the first axis Q1 and the second axis Q2 is fixed, the edge between the first axis Q1 and the third axis Q3 rotates, the edge between the second axis Q2 and the fourth axis Q4 rotates, and the edge between the third axis Q3 and the fourth axis Q4 moves while always remaining parallel to the edge between the first axis Q1 and the second axis Q2. In other words, the second component F, the first damping structure 1, the second damping structure 2, and the connecting member 3 form a four-bar linkage.

[0193] In other alternative embodiments, the axes can also 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, as well as 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.

[0194] As previously mentioned, the electronic device 200 may be provided with some limiting structures to limit the angle at which the bracket 81 can be opened relative to the electronic device body 7, or to remind the user of the optimal angle at which the bracket 81 supports the electronic device body 7. These limiting structures may be provided in the hinge mechanism 100, or more specifically, on the damping structure, utilizing the shape of the damping structure itself for limiting.

[0195] As shown in Figures 15-18b, in one embodiment, a first limiting portion 13 is provided in the first sleeve 12, and a portion of the outer surface of the first rotating shaft 11 along its circumference is configured as a plane. The first limiting portion 13 is an elastic structure (such as a spring, etc., which is not limited in this application). When the first rotating shaft 11 rotates to the first position (the position shown in Figures 18a-18b) relative to the first sleeve 12, the first limiting portion 13 cooperates with the first rotating shaft 11 through a plane. Alternatively, it can be understood that an elastic first limiting portion 13 is provided between the first rotating shaft 11 and the first sleeve 12, and along the circumference of the first rotating shaft 11, a portion of the outer surface of the first rotating shaft 11 is an arcuate surface, and another portion of the outer surface is a plane. When the first rotating shaft 11 rotates relative to the first sleeve 12, both the arcuate surface and the plane can cooperate with the first limiting portion 13. When the first rotating shaft 11 cooperates with the first limiting portion 13 through the arc surface, the first limiting portion 13 is compressed by the first rotating shaft 11 into a sheet-like structure close to the inner wall surface of the first sleeve 12. At this time, 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, so the user can rotate the bracket 81 smoothly and with less effort. When the first rotating shaft 11 cooperates with the first limiting portion 13 through the plane, the first limiting portion 13 rebounds to a shape with a plane. At this time, 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, so the user has more difficulty in rotating. Among them, the first position is the limiting position of the first damping structure 1. There can be one or more first positions, and each first position corresponds to a specific angle. For example, the first damping structure 1 can be set to: at a specific angle (for example, the bracket 81 is opened 60°, 70°, 75°, etc. relative to the electronic device body 7, without specific limitation), the first rotating shaft 11 cooperates with the first limiting portion 13 through a plane, and the user rotates the bracket 81 from smoothly to laboriously, and the electronic device 200 is placed on the desktop at a specific angle for use, with stable support and better user experience.

[0196] In other alternative embodiments, the first limiting portion 13 may also adopt other structures. For example, a groove may be provided in the inner wall of the first sleeve 12, and the first limiting portion 13 may be an elastic member 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 member 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 (that is, the first rotating shaft 11 rotates to the first position relative to the first sleeve 12), the elastic member 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. Among them, the elastic part can be a structure such as a spring that is elastic 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, one end of the spring is connected to the bottom of the groove, and the other end is connected to the protrusion, and the protrusion cooperates with the first rotating shaft 11.

[0197] In one embodiment, a second limiting portion 23 is provided within the second sleeve 22, and a portion of the outer surface of the second rotating shaft 21 along its circumference is configured as a plane. The second limiting portion 23 is an elastic structure. When the second rotating shaft 21 rotates to the second position relative to the second sleeve 22, the second limiting portion 23 and the second rotating shaft 21 cooperate through a plane. The second position is the limiting position of the second damping structure 2, i.e., the position shown in Figures 18a and 18b. The function and working principle of the second limiting portion 23 are the same as those of the first limiting portion 13 and will not be further described here. This application does not limit the specific structure of the second limiting portion 23, and the design of the first limiting portion 13 can be referred to.

[0198] Those skilled in the art will appreciate that only one of the first damping structure 1 and the second damping structure 2 may be provided with a limiting portion while the other one is not provided with a limiting portion, or both damping structures may be provided with a limiting portion, and this application does not impose any restrictions on this.

[0199] In one embodiment, multiple stoppers may be provided in the first damping structure 1 or the second damping structure 2, each corresponding to a different set angle. The specific number of stoppers in each damping structure is not limited and may be one, two, three, or more. In an exemplary scenario, two first stoppers 13 may 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 stoppers 13 form a planar fit. Further rotation of the bracket 81 to a 60° opening relative to the electronic device body 7 results in a planar fit between the first rotating shaft 11 and the other first stopper 13. At both specific angles, the damping force of the hinge mechanism 100 is relatively high, and the bracket 81 can firmly support the electronic device body 7. Users can select the desired angle based on their height, desktop height, and other scenarios. In an alternative embodiment, stoppers may be provided in both the first damping structure 1 and the second damping structure 2. The stoppers in the first damping structure 1 and the second damping structure 2 can correspond to different angles and usage scenarios, which is not limited in this application.

[0200] It will be understood by those skilled in the art 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 can be a split structure. The second sleeve 22 and the connector 3 can be integrally formed or can be a split structure. This application does not impose any restrictions on this. As shown in Figures 13-18b, in one embodiment, the connector 3 is configured as a connecting rod, and the two ends of the connecting rod respectively form the first sleeve 12 and the second sleeve 22, that is, the first sleeve 12 and the second sleeve 22 are both integrally formed with the connector 3, which has a simple structure and is easy to process.

[0201] Those skilled in the art will appreciate that the hinge 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. Some structures for connection and fixation may be provided between the hinge mechanism 100 and the second component F, as well as between the first component E. This application does not limit the connection method between the hinge mechanism 100 and the second component F and the first component E. The following exemplifies the possible structures with reference to the accompanying drawings.

[0202] Please refer to Figures 19-23, Figure 19 is a structural schematic diagram of the first fixing member in the rotating shaft mechanism of the embodiment of the present application; Figure 20 is a schematic diagram of the connection structure of the first fixing member and the first damping structure in the rotating shaft mechanism of the embodiment of the present application; Figure 21 is a structural schematic diagram of the second fixing member in the rotating shaft mechanism of the embodiment of the present application; Figure 22 is a schematic diagram of the matching relationship between the first fixing member and the second fixing member in the rotating shaft mechanism of the embodiment of the present application; Figure 23 is a schematic diagram of the matching relationship between the second fixing member and the second damping structure in the rotating shaft mechanism of the embodiment of the present application.

[0203] As shown in Figures 13-23, 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. The first damping structure 1 can be mounted to the first component E via the first fixing member 4. 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. The second damping structure 2 can be mounted to the second component F via the second fixing member 5.

[0204] 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. It is rotatably connected to the second fixing member 5 through the first fixing member 4 and is 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 hinge 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 hinge mechanism 100. For example, the second damping structure 2 may be directly mounted on the second component F. This is not limited in the present application.

[0205] It should be noted that the specific shapes of the first fixing member 4 and the second fixing member 5 are not limited. As shown in Figures 13, 17, and 21-23, in one embodiment, the second fixing member 5 includes a base 51 extending along the second direction Y, and two extension arms 52 connected to the two ends of the base 51 in the second direction Y. Each of the two extension arms 52 extends along the first direction X and protrudes from the base 51 toward the same side, so that an installation space 50 is formed between the two extension arms 52 and the base 51. The first damping structure 1, the second damping structure 2, the connecting member 3, and the first fixing member 4 are all installed in 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 close 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. Or it can be understood that the second fixing member 5 is a U-shaped structure as a whole, the second damping structure 2, the first damping structure 1 and the first fixing member 4 are arranged in sequence along the first direction X in the U-shaped structure, and the second damping structure 2 is close to the base 51 of the second fixing member 5.

[0206] Among them, 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. A plurality of fixing holes 510 are provided on the base 51, and the base 51 and the second component F can be fixedly connected by fasteners such as screws and bolts. An extension platform 521 protruding from the extension arm 52 is provided on the extension arm 52, and the extension platform 521 is also provided with a fixing hole 5210, and the extension arm 52 and the second component F can be fixedly connected by fasteners such as screws and bolts. It will be understood by those skilled in the art that the number of fixing holes 510 on the base 51 is not limited, and the number of extension platforms 521 on the extension arm 52 and the number of fixing holes 5210 on the extension platform 521 are not limited, and can be set as needed.

[0207] Those skilled in the art will appreciate that the second fixing member 5 can be an integral structure or a split structure. In one embodiment, the second fixing member 5 has two fixing portions 53, each of the two fixing portions 53 including 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 fixing portions 53 are connected and fixedly connected to form the base 51 of the second fixing member 5, and the second portions 532 of the two fixing portions 53 respectively constitute the two extension arms 52 of the second fixing member 5. Alternatively, it can be understood that the second fixing member 5 is split from the base 51 into two fixing portions 53, each fixing portion 53 including an extension arm 52 and a portion of the base 51. The two fixing portions 53 can be fixedly connected by welding, bolting, bonding, riveting, etc., without limitation. In one embodiment, the mating surfaces of the two fixing portions 53 are configured as two inverted L-shaped structures. The fastener is passed through the fixing holes 510 at corresponding positions on the base 51 and can simultaneously pass through the two fixing portions 53 to firmly combine the two fixing portions 53.

[0208] As shown in Figures 13, 17, 19-20, and 22, in one embodiment, the first fixing member 4 includes a base 41, which is fixedly connected to the first component E. The specific connection between the base 41 and the first component E will be described later in conjunction with the structure of the bracket 81 and will not be elaborated here.

[0209] In one embodiment, a mounting portion 42 is further provided on the first fixing member 4, and the mounting portion 42 is used to mount the first rotating shaft 11. The mounting portion 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 portion 42 to connect the first component E with the first rotating shaft 11 through the mounting portion 42.

[0210] It should be noted that the specific structure of the mounting portion 42 is not limited. In one embodiment, the mounting portion 42 includes two bosses 421 spaced apart in the second direction Y, the first damping structure 1 is located between the two bosses 421, and each of the two bosses 421 is provided with 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 are respectively passed through the through holes of the two bosses 421. In combination with the above, it can be seen that 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 remain 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 bosses 421, or it can be completely fixedly connected to the first fixing member 4. This application does not impose any restrictions on this. In one embodiment, the two ends of the first rotating shaft 11 are fixedly connected to the two bosses 421, that is, the first rotating shaft 11 is completely fixedly connected to the first fixing member 4, preventing the first rotating shaft 11 from sliding in the through holes of the first sleeve 12 and the bosses 421. The connection is more reliable and the damping force of the first damping structure 1 can be better transmitted to the first component E. The fixing method of the first rotating shaft 11 and the bosses 421 is not limited, and the two can be fixed by bonding, welding, structural limiting, etc. In one embodiment, a portion of the outer circumference of the first rotating shaft 11 can be set as a plane, and the corresponding position on the inner wall surface of the through hole 4210 on each boss 421 can be set as a plane. The first rotating shaft 11 and each boss 421 cooperate through the plane to limit the relative rotation between the two.

[0211] It should be noted that the manner in which the first fixing member 4 rotates relative to the second fixing member 5 is not limited. For example, a connecting shaft may be provided between the first fixing member 4 and the second fixing member 5, and the connecting shaft rotates relative to the second fixing member 5 about the first axis Q1, thereby allowing the first fixing member 4 to 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, such 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 influence of the first fixing member 4.

[0212] Specifically, in one embodiment, the first fixing member 4 further includes two pivoting arms 43, which are disposed at opposite ends of the base 41 along the second direction Y and are respectively connected to the opposite ends of the base 41. Furthermore, the two pivoting arms 43 correspond one-to-one with the two extension arms 52 of the second fixing member 5. Each of the two pivoting arms 43 is slidably connected to the 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 arcuate groove 611 and an arcuate slider 612 that are slidably connected to each other. One of the arcuate groove 611 and the arcuate slider 612 of the first sliding structure 61 is disposed on the pivoting 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 slot 611, and the first axis Q1 passes through the center of the arc-shaped track. The first fixing member 4 can rotate around the first axis Q1 relative to the second fixing member 5, and the first component E and the first damping structure 1 can rotate around the first axis Q1 relative to the second component F.

[0213] In one embodiment, the arcuate slot 611 of the first sliding structure 61 is disposed on the rotating arm 43 of the first fixing member 4, and the arcuate slider 612 is disposed on the extension arm 52 of the second fixing member 5. In an alternative embodiment, the arcuate slot 611 of the first sliding structure 61 may also be disposed on the extension arm 52 of the second fixing member 5, and the arcuate slider 612 may also be disposed on the rotating arm 43 of the first fixing member 4, and this application is not limited thereto.

[0214] Those skilled in the art will appreciate that the second rotating shaft 21 is mounted on the second fixing member 5. If the second rotating shaft 21 is rotatable relative to the second fixing member 5, 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 fixing member 5 is not limited. In one embodiment, the second damping structure 2 is slidably connected to the second fixing member 5, such that the second damping structure 2 can rotate relative to the second fixing member 5 about the second axis Q2.

[0215] Specifically, as shown in Figures 17 and 23, in one embodiment, the second damping structure 2 further includes two sleeves 24 spaced apart along the second direction Y. The two sleeves 24 are respectively sleeved on both ends of the second rotating shaft 21. The two sleeves 24 correspond one-to-one with the two extension arms 52 of the second fixing member 5. Each of the two sleeves 24 is slidably connected to the corresponding extension arm 52 via a second sliding structure 62, so that the second damping structure 2 can rotate about the second axis Q2 relative to the second fixing member 5. The second sliding structure 62 includes an arcuate slider 622 and an arcuate slot 621 that are slidably connected to each other. One of the arcuate slider 622 and the arcuate slot 621 of the second sliding structure 62 is disposed on the sleeve 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 slot 621, and 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 fixing member 5 through the shaft sleeve 24, and the second damping structure 2 can rotate around the second axis Q2 relative to the second component F.

[0216] In one embodiment, the arcuate slider 622 of the second sliding structure 62 is disposed on the shaft sleeve 24, and the arcuate slot 621 is disposed on the extension arm 52 of the second fixing member 5.

[0217] 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 hinge mechanism 100. The following exemplifies the installation method between the hinge mechanism 100 and the bracket 81 with reference to the accompanying drawings.

[0218] Please refer to Figures 24-26b, Figure 24 is a schematic diagram of the decomposed structure of the rotating shaft mechanism and the bracket according to the embodiment of the present application; Figure 25 is a schematic diagram of the connection structure of the rotating shaft mechanism and the bracket according to the embodiment of the present application; Figure 26a is a sectional view in the BB direction in Figure 25; Figure 26b is a sectional view in the CC direction in Figure 25.

[0219] As shown in Figures 24 to 26b, 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 install the bracket 81 on the rotating shaft mechanism 100. Specifically, in one embodiment, the base 41 is provided with a through hole 410 that passes through the base 41 along the first direction X. The number of through holes 410 is not limited and can be 1, 2, 3, etc., and can be specifically set as needed. In one embodiment, two through holes 410 are provided on the base 41, and the two through holes 410 are respectively provided on both sides of the mounting portion 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, respectively. Each mounting member 812 is provided with a fixing hole 8120. Fasteners such as screws and bolts can be sequentially passed through the through-holes 410 on the base 41 and the fixing holes 8120 on the mounting members 812 to securely connect the bracket 81 to the first fixing member 4 of the rotating shaft mechanism 100. In other alternative embodiments, the base 41 and the bracket 81 can also be securely connected by bonding, welding, bolting, riveting, or the like, which is not limited in this application.

[0220] Those skilled in the art will appreciate that when a user rotates bracket 81, torque is generated between bracket 81 and pivot mechanism 100. If bracket 81 and pivot mechanism 100 are connected solely with fasteners, frequent use of bracket 81 may result in deformation of bracket 81, loosening of fasteners, and other issues. To enhance the reliability of the connection between bracket 81 and pivot mechanism 100, a connection reinforcement structure may be provided between bracket 81 and pivot mechanism 100. For example, a pin or other component may be provided between mounting member 812 and base 41 to strengthen the connection. The specific form of the structure is not limited.

[0221] As shown in Figures 24-26b, in one embodiment, a receiving groove is provided within the mounting member 812, and a portion of the structure of the hinge mechanism 100 is located within the receiving groove. This increases the connection area between the bracket 81 and the hinge mechanism 100, thereby improving the reliability of the connection between the two. 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 of the hinge mechanism 100 that cooperates with the receiving groove.

[0222] In one embodiment, the mounting member 812 includes a first receiving groove 8121. The first fixing member 4 also includes a protrusion 44 connected to the base 41. The protrusion 44 protrudes from the base 41 on a side facing away from the first damping structure 1 in the first direction X. The protrusion 44 can be embedded in the first receiving groove 8121, thereby enhancing 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 either side of the first receiving groove 8121 in the second direction Y and correspond to the two pivoting arms 43 of the first fixing member 4 in the first direction X. The two pivoting arms 43 can be respectively received in the two second receiving grooves 8122. The specific forms of the first receiving groove 8121 and the second receiving groove 8122 are 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 which it is located.

[0223] 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 arcuate groove, and the pivoting arms 43 on the base 41 are also configured as an arcuate groove, and the arcuate pivoting arms 43 can be engaged with the arcuate second receiving groove 8122. In one embodiment, the end of the second fixing member 5 connected to each pivoting arm 43 is also configured as an arcuate structure. When the bracket 81 is in the stowed state, the end of the second fixing member 5 can also be received in the second receiving groove 8122. When the bracket 81 is switched from the stowed state to the open state, the end of the second fixing member 5 can gradually disengage the second receiving groove 8122. In other alternative embodiments, the shape of the first receiving groove 8121 can also be different from that of the protrusion 44, and the shape of the second receiving groove 8122 can also be different from that of the pivoting arms 43. These are not listed here.

[0224] Obviously, those skilled in the art may make various modifications and variations to this application without departing from the scope of this application. Thus, if these modifications and variations fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.
