Description

Technical Field

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

[0002] As flexible folding screen technology matures, the application of folding terminal products is becoming more and more extensive. Folding terminal products (such as folding mobile phones, folding tablets, folding computers, etc.) need to meet higher appearance and better experience in order to be accepted by consumers. At present, the rotation of folding terminal products is usually achieved through a slide. However, the structural setting of the existing swing arm slide causes insufficient overlap of the swing arm, resulting in poor reliability of foldable electronic devices during use. Summary of the invention

[0003] The embodiments of the present application provide a hinge mechanism and an electronic device. The configuration of the hinge mechanism is beneficial to improving the reliability of the electronic device while ensuring the rotation of the hinge.

[0004] In a first aspect, the present application provides a pivot mechanism, which includes a base, at least two swing arm assemblies and at least two door panel assemblies.

[0005] The swing arm assembly is respectively arranged on both sides of the base, and one end of the swing arm assembly is rotatably connected to the base; at least two door panel assemblies are respectively arranged on both sides of the base;

[0006] In the swing arm assembly and the door panel assembly on the same side of the base, one end of the door panel assembly is connected to an end of the swing arm assembly away from the base; one end of the door panel assembly connected to the swing arm assembly and one end of the swing arm assembly connected to the door panel assembly, one of which is provided with a first circular arc sliding portion and a second circular arc sliding fitting portion, and the other is provided with a first circular arc sliding fitting portion and a second circular arc sliding portion; the first circular arc sliding portion is slidably fitted with the first circular arc sliding fitting portion, and the second circular arc sliding portion is slidably fitted with the second circular arc sliding fitting portion, so that the swing arm assembly is rotatably connected to the door panel assembly.

[0007] Along the length direction of the base, the first arc-shaped sliding portion and the second arc-shaped sliding fitting portion are alternately arranged; the first arc-shaped sliding fitting portion and the second arc-shaped sliding portion are alternately arranged.

[0008] Similarly, the door panel assembly is provided with two first arc-shaped sliding fitting parts and a second arc-shaped sliding part at one end close to the swing arm assembly. The fitting manner of the two first arc-shaped sliding fitting parts and the second arc-shaped sliding parts on the door panel assembly is the same as that of the swing arm assembly, which will not be repeated here.

[0009] The two first arc-shaped sliding fitting parts can allow the first arc-shaped sliding part to slide thereon, and the second arc-shaped sliding fitting part can allow the second arc-shaped sliding part to slide thereon, and the sliding fitting between the second arc-shaped sliding part and the second arc-shaped sliding fitting part and the sliding fitting between the third arc-shaped sliding part and the third arc-shaped sliding fitting part can make the swing arm assembly rotatably connected to the door panel assembly.

[0010] In addition, by arranging two of the first arc-shaped sliding and the second arc-shaped sliding matching parts on the swing arm assembly and two of the first arc-shaped sliding matching parts and the second arc-shaped sliding parts on the door panel assembly, on the one hand, the sliding trajectory of the swing arm assembly and the door panel assembly is jointly defined by the two first arc-shaped sliding parts and the two first arc-shaped sliding parts and the second arc-shaped sliding and the second arc-shaped sliding matching parts, which can reduce the assembly accuracy requirements of the swing arm assembly and the door panel assembly, thereby reducing the processing difficulty and processing cost of the swing arm assembly and the door panel assembly.

[0011] On the other hand, the sliding trajectory of the swing arm assembly and the door panel assembly is jointly defined by the two first arc-shaped sliding parts and the second arc-shaped sliding matching parts and the two first arc-shaped sliding matching parts and the second arc-shaped sliding parts. The first arc-shaped sliding part and the second arc-shaped sliding part and the two first arc-shaped sliding matching parts and the second arc-shaped sliding part are arranged in a distributed manner. The distributed arrangement of multiple arc-shaped sliding matching parts can increase the overlap amount between the swing arm assembly and the door panel assembly, increase the connection strength between the swing arm assembly and the door panel assembly, make the swing arm assembly and the door panel assembly not easy to fall out when sliding relative to each other, and have good reliability.

[0012] In a possible implementation, the swing arms on both sides of the base may be relatively arranged, that is, they are approximately in the same position in the length direction of the base, or they may not be relatively arranged, that is, they are staggered along the length direction of the base; the door panel assemblies on both sides of the base may be relatively arranged, that is, they are approximately in the same position in the length direction of the base, or they may not be relatively arranged, that is, they are staggered along the length direction of the base.

Compared with point contact and first contact, this is conducive to improving the stability of the rotational matching between the swing arm assembly and the door panel assembly.

[0016] In a possible embodiment, one of the two first arc-shaped sliding parts and the two first arc-shaped sliding matching parts can be an arc-shaped groove, and the other can include multiple sub-sliding parts; one of the second arc-shaped sliding part and the second arc-shaped sliding matching part can be an arc-shaped groove, and the other can include multiple sub-sliding parts, and the sub-sliding part can be a rod-shaped structure, a block structure, etc.

[0019] It can be understood that the connection method between the connecting member and the door panel can refer to the connection method between the swing arm assembly and the door panel assembly in the above embodiment, and its specific effects and structural settings will not be repeated here.

The first swing arm is rotatably connected to the second swing arm, and one of the ends of the first swing arm connected to the second swing arm and the second swing arm connected to the first swing arm is provided with two fifth arc-shaped sliding portions and a sixth arc-shaped sliding matching portion, and the other is provided with two fifth arc-shaped sliding matching portions and a sixth arc-shaped sliding portion.

DETAILED DESCRIPTION

[0051] For ease of understanding, the terms involved in the embodiments of the present application are first explained.

[0052] And / or: It is just a way to describe the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0053] Multiple: refers to two or more than two.

[0054] Connection: should be understood in a broad sense. For example, A and B are connected, which can be either direct or indirect through an intermediary.

[0055] The specific implementation of the present application will be clearly described below in conjunction with the accompanying drawings.

[0056] The embodiments of the present application provide a rotating mechanism and an electronic device using the rotating mechanism. The structural arrangement of the rotating mechanism is conducive to achieving the thinning of the entire device while ensuring the rotational movement of the swing arm.

[0057] The electronic device may be any device with foldable performance, which can be unfolded and closed under the operation of the user. The electronic device includes but is not limited to a cell phone, a notebook computer, a tablet personal computer, a laptop computer, a personal digital assistant, a wearable device or a mobile device, etc.

[0058] In order to make the purpose, technical solutions and advantages of the present application more clear, in the embodiments of the present application, the electronic device is taken as an example of a mobile phone.

[0059] See also Figure 1 and Figure 2 , Figure 1 shows a schematic structural diagram of an electronic device 100 provided in some embodiments of the present application in an unfolded state, Figure 2 Shows Figure 1 The schematic diagram of the structure of the electronic device 100 in the folded state is shown. Figure 3 Shows Figure 1 A schematic diagram of the electronic device 100 in an intermediate state.

[0060] Under different usage requirements, the terminal device 100 can be unfolded to the unfolded state, folded to the folded state, or in an intermediate state between the unfolded state and the folded state. It should be understood that the intermediate state can be any state of the terminal device 100 between the unfolded state and the folded state, but not the only state.

[0061] The terminal device 100 includes a folding device 400 and a folding screen 300, and the folding screen 300 is arranged on the folding device 400. Among them, the folding device 400 can provide support and protection for the folding screen 300, and can be folded or unfolded. The folding screen 300 is a flexible screen, so that it can be folded or unfolded together with the folding device 400. It can be understood that the folding screen 300 can be used to display information and provide an interactive interface for the user, and can be a variety of types of display screens.

[0062] like Figure 4As shown, the folding device 400 includes a hinge mechanism 200, a first shell 130 and a second shell 140. The hinge mechanism 200 is located between the first shell 120 and the second shell 140, and is respectively connected to the first shell 130 and the second shell 140. The first shell 130 and the second shell 140 can rotate relative to each other based on the hinge mechanism 200, so that they can rotate relatively close to each other (i.e., rotate towards each other) to put the terminal device 100 in a folded state, and can rotate relatively away from each other (i.e., rotate away from each other) to put the terminal device 100 in an unfolded state.

[0063] It is understandable that the number of the rotating shaft mechanism 200 may be one or more. When the number of the rotating shaft mechanism 200 is multiple, each rotating shaft mechanism 200 may be arranged in sequence and spaced apart, and all are located between the first shell 130 and the second shell 140 .

[0064] Please continue reading Figures 1 to 4 The folding screen 300 is arranged on the first shell 130 and the second shell 140, and can be folded or unfolded as the first shell 130 and the second shell 140 rotate. The folding screen 300 has a foldable area 150, and the position of the foldable area 150 corresponds to the position of the hinge mechanism 200, that is, the foldable area 150 is arranged opposite to the hinge mechanism 200. The foldable area 150 is flexible, so that when the first shell 130 and the second shell 140 rotate relative to each other, the folding screen 300 can be folded by bending the foldable area 150. When the folding screen 300 is in a folded state, the foldable area 150 can be in a water drop shape or a U shape, but is not limited to this shape.

[0065] It can be understood that the portion of the folding screen 300 corresponding to the first housing 130 can be flexible or rigid. The portion of the folding screen 300 corresponding to the second housing 140 can be flexible or rigid.

[0066] The front side of the folding screen 300 is the side facing away from the hinge mechanism 200, that is, the display surface of the folding screen 300 for displaying images. The back side of the folding screen 300 is the side facing the hinge mechanism 200, and can also be regarded as the non-display surface of the folding screen 300.

[0067] When the terminal device 100 is in the unfolded state, the folding device 400 and the folding screen 300 are also in the unfolded state, and the first surface of the first housing 130 for mounting the folding screen 300 and the second surface of the second housing 140 for mounting the folding screen 300 are approximately in the same plane, that is, the angle between the first surface and the second surface is approximately 180°; at this time, the folding screen 300 is approximately flat, so that the terminal device 100 has a larger display area. It should be understood that when the folding device 400 is in the unfolded state, the angle between the first surface and the second surface is not limited to an absolute 180°, and the angle between the two can also be greater than or less than 180°, but close to 180°, for example, the angle can range from 165 to 190° (for example, 170°, 173°, 175°, 182°, 185°, etc., but not limited thereto), and the unfolding of the folding screen 300 can also be achieved.

[0068] When the terminal device 100 is in the folded state, the folding device 400 and the folding screen 300 are also in the folded state, and the first surface of the first housing 130 for mounting the folding screen 300 and the second surface of the second housing 140 for mounting the folding screen 300 are arranged relatively and substantially parallel, that is, the angle between the first surface and the second surface is substantially 0°; at this time, the folding screen 300 is folded relative to the foldable portion 150 and presents a folded state, so as to facilitate the storage of the terminal device 100. It should be understood that when the folding device 400 is in the folded state, it is not limited to that the first surface and the second surface are absolutely parallel, and the angle between the two can also be greater than 0°, but close to 0°, for example, the angle can range from 0° to 15 (for example, 1°, 2°, 3°, 5°, 10°, etc., but not limited thereto), and the folding of the folding screen 300 can also be achieved.

[0069] In some embodiments, the electronic device 100 may be an inward-folding terminal device, and the folding screen 100 is an inward-folding folding screen. After the folding screen 300 is folded, the folding screen 300 is located between the first housing 130 and the second housing 140.

[0070] Of course, in some other embodiments, the terminal device 100 may also be an outward folding terminal device, and the folding screen 300 is an outward folding folding screen. After the folding screen 300 is folded, the display surface of the folding screen 300 is exposed, and the first shell 130 and the second shell 140 are located between the folding screen 300.

[0071] In some embodiments, at least one of the first shell 130 and the second shell 140 may be provided with an installation space for installing the electronic components of the terminal device 100. For example, the electronic components may include circuit boards, batteries, receivers, speakers, cameras, etc., but are not limited thereto. Among them, the circuit board can integrate the electronic components such as the central controller, storage unit, antenna module, power management module, etc. of the terminal device 100, and the battery can power the folding screen 300, circuit boards, receivers, speakers, cameras and other electronic components. The shape set structure of the first shell 130 and the second shell 140 may be the same or different, which is not limited in the embodiment of the present application. The first shell 130 and the second shell 140 may be a middle frame structure, and the specific shape and structure may be set as needed, which is not limited in the embodiment of the present application.

[0072] Next, the rotating shaft mechanism 200 provided in the embodiment of the present application will be described in detail.

[0073] To facilitate the description of the embodiments below, an XYZ three-axis rectangular coordinate system is established, and the width direction of the hinge mechanism 200 is defined as the X-axis direction, which is parallel to the direction in which the first shell 130 points to the second shell 140 when the terminal device 100 is in the unfolded state; the length direction of the hinge mechanism 200 is defined as the Y-axis direction, which is parallel to the direction in which one end of the first shell 130 points to the opposite other end when the terminal device 100 is in the unfolded state; the thickness direction of the hinge mechanism 200 is defined as the Z-axis direction, which is parallel to the direction in which the first shell 130 points to the folding screen 300 when the terminal device 100 is in the unfolded state, that is, parallel to the thickness direction of the terminal device 100. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other. The X-axis direction includes the positive direction of the X-axis and the negative direction of the X-axis, and the Y-axis direction and the Z-axis direction are the same. It should be understood that the coordinate system of the hinge mechanism 100 can be flexibly set according to actual needs. This application only gives an example and cannot be considered as a special limitation to this application.

[0074] Figure 5 Shows Figure 4 Exploded diagram of the central shaft mechanism. Figure 6 yes Figure 4 A schematic diagram of the folded state of the central rotating shaft mechanism 200, Figure 7 yes Figure 6 Exploded diagram of the central shaft mechanism. Figure 8 A partial exploded view of the shaft mechanism of some embodiments of the present application.

[0075] like Figures 5 to 8As shown, the hinge mechanism 200 includes a base 210, at least two door panel assemblies 340, and at least two swing arm assemblies 120. The swing arm assemblies 120 and the door panel assemblies 340 on the same side of the base 210 are rotatably connected. Each door panel assembly 120 is respectively arranged on both sides of the base 210, and each swing arm assembly 120 is respectively arranged on both sides of the base 210. Among the swing arm assemblies 120 located on both sides of the base 210, one end of the swing arm assembly 120 is rotatably connected to the base 210. The rotatable connection form of the swing arm assembly 120 and the base 210 is not limited in this application, as long as the swing arm assembly 120 can rotate around the base 210. For example, the connection interface between the swing arm assembly 120 and the base 210 can be that an arc-shaped sliding protrusion 110 is provided on one end of the swing arm assembly 340 close to the base 210, and a sliding groove 211 is provided on the base 210 to cooperate with the arc-shaped sliding protrusion. The sliding protrusion 110 slides in cooperation with the sliding groove 211 to enable the swing arm assembly 120 to be rotatably connected to the base 210.

[0076] In some embodiments, one end of the swing arm assembly 120 close to the base 210 can be connected to the base 210 by various rotational connection methods, so that the swing arm assembly 120 can rotate relative to the base 210 while being connected to the base 210, and the axes of the rotation shafts of each swing arm assembly 120 relative to the base 10 can be arranged roughly parallel, of course there can be a certain deviation but close to parallel, that is, manufacturing errors, assembly errors, etc. can be allowed. The rotation axis of the swing arm assembly 120 relative to the base 210 can be roughly parallel to the length direction of the base 210.

[0077] It is understood that the base 210 can support and connect the swing arm assembly 120, and can be various regular or irregular structures, such as a block structure, a frame structure, a shell structure, a plate structure, etc., but not limited thereto. The base 210 can be a single component or an assembly including multiple assembled components. In some cases, the base 210 is also called a main shaft, a main body, etc.

[0078] Fig. 9 for Figure 8 A schematic diagram of a folded state of a swing arm in a rotating shaft mechanism shown; Fig.10 This is a schematic structural diagram of a first swing arm in some embodiments of the present application; Fig.11 is a structural schematic diagram of the second swing arm; Fig.12 It is a schematic diagram of the cooperation between the first swing arm and the second swing arm.

[0079] In some embodiments, Figures 9 to 12As shown, the swing arm assembly 120 located on both sides of the base 210 includes a first swing arm 10 and a second swing arm 20, and the first swing arm 10 is rotatably connected to the second swing arm 20. Among the first swing arms 10 located on both sides of the base 210, one end of the first swing arm 10 is rotatably connected to the base 210, and the rotatable connection form of the first swing arm 10 and the base 210 is not limited in this application, as long as the first swing arm 10 can rotate around the base 210, and the other end of the first swing arm 10 is connected to the second swing arm 20.

[0080] Specifically, Fig.10 As shown, in the first swing arm 10 and the second swing arm 20 located on the same side of the base 210, two fifth arc-shaped sliding parts 101 and a sixth arc-shaped sliding fitting part 102 are provided on one end of the first swing arm 10 close to the second swing arm 20, and the two fifth arc-shaped sliding parts 101 are respectively located on the opposite sides of the sixth arc-shaped sliding fitting part 102, and are arranged side by side with the third arc-shaped sliding fitting part 102 along the length direction of the base 210.

[0081] like Fig.11 As shown, two fifth circular arc-shaped sliding fitting parts 201 and a sixth circular arc-shaped sliding part 202 are provided on one end of the second swing arm 20 close to the first swing arm 10. The two fifth circular arc-shaped sliding fitting parts 201 are respectively located on the opposite sides of the sixth circular arc-shaped sliding part 202, and are arranged side by side with the sixth circular arc-shaped sliding part 202 along the length direction of the base 210.

[0082] The arcuate surfaces of the two fifth arcuate sliding parts 101 on the first swing arm 10 overlap the inner wall surfaces of the two arcuate sliding fitting parts 201 on the second swing arm 20, so that the two fifth arcuate sliding parts 101 on the first swing arm 10 slide and fit with the two fifth arcuate sliding fitting parts 201 on the second swing arm 20. The arcuate surface of the sixth arcuate sliding part 202 on the second swing arm 20 overlaps the inner wall surface of the third arcuate sliding fitting part 102 on the first swing arm 10, so that the third arcuate sliding fitting part 102 on the first swing arm 10 slides and fits with the third arcuate sliding part 202 on the second swing arm 20.

[0083] It can be understood that the two fifth circular arc-shaped sliding fitting parts 201 can allow the two fifth circular arc-shaped sliding parts 101 to slide thereon, and the sixth circular arc-shaped sliding fitting part 202 can allow the sixth circular arc-shaped sliding part 102 to slide thereon, and through the sliding fit between the two fifth circular arc-shaped sliding parts 101 and the two fifth circular arc-shaped sliding fitting parts 201 and the sliding fit between the sixth circular arc-shaped sliding part 202 and the sixth circular arc-shaped sliding fitting part 102, the first swing arm 10 and the second swing arm 20 are rotatably connected.

[0084] By providing two fifth circular arc sliding parts 101 and one sixth circular arc sliding fitting part 102 on the first swing arm 10 and providing two fifth circular arc sliding fitting parts 201 and a sixth circular arc sliding part 202 on the second swing arm 20, the sliding trajectories of the first swing arm 10 and the second swing arm 20 can be jointly defined by the fifth circular arc sliding fitting part 201 and the sixth circular arc sliding fitting part 102. On the one hand, the sliding trajectories of the first swing arm 10 and the second swing arm 20 are jointly defined by the two fifth circular arc sliding fitting parts 201 and the sixth circular arc sliding fitting part 102, which can reduce the precision requirements on the fifth circular arc sliding fitting part 201 and the sixth circular arc sliding fitting part 102, thereby reducing the processing difficulty and processing cost of the swing arm. On the other hand, the sliding trajectory of the first swing arm 10 and the second swing arm 20 is jointly defined by the two fifth arc-shaped sliding fitting parts 201 and the sixth arc-shaped sliding fitting parts 102, so that the fifth arc-shaped sliding fitting parts 201 and the sixth arc-shaped sliding fitting parts 102 can be arranged in a distributed manner. The distributed arrangement of multiple arc-shaped sliding fitting parts can increase the overlap amount between the first swing arm 10 and the second swing arm 20, increase the connection strength between the first swing arm 10 and the second swing arm 20, make the first swing arm 10 and the second swing arm 20 not easy to fall out when sliding relative to each other, and have good reliability.

[0085] It can be understood that the first swing arms 10 are arranged on both sides of the base 210, but the number of the first swing arm assemblies on each side can be one or more, the number of the first swing arms 10 on each side can be one or more, and the number of the first swing arms 10 on both sides of the base 210 can be the same or different. The second swing arms 20 are respectively arranged on both sides of the base 210, which means that the second swing arms 20 are arranged on both sides of the base 210, but the number of the second swing arms 20 on each side can be one or more, and the number of the second swing arms 20 on both sides of the base 210 can be the same or different.

[0086] It should be understood that the two sides of the base 210 refer to the two sides with the central longitudinal section of the base 210 as the dividing interface, and the central longitudinal section is a plane parallel to the length direction (i.e., the Y-axis direction) and thickness direction (i.e., the Z-axis direction) of the base 210 and bisects the base 10 along the width direction (i.e., the X-axis direction) of the base 210. By analogy, the two sides of the components appearing in the following text refer to the two sides with the central longitudinal section of the component as the dividing interface. Optionally, the first swing arms 10 on both sides of the base 210 can be arranged relative to each other, that is, they are approximately in the same position in the length direction of the base 210. Optionally, the second swing arms 20 on both sides of the base 210 can be arranged relative to each other, that is, they are approximately in the same position in the length direction of the base 210. Figure 6 and Figure 7Of course, in some other embodiments, the first swing arms on both sides of the base 210 may not be arranged opposite to each other, that is, they are staggered along the length direction of the base 210, and the second swing arms on both sides of the base 210 may not be arranged opposite to each other, that is, they are staggered along the length direction of the base 210, and the first swing arm 10 and the second swing arm 20 located on the same side of the base 210 are in a rotationally connected state.

[0087] Since the first swing arm 10 and the second swing arm 20 located on the same side of the base 210 are rotatably connected by the fifth arc-shaped sliding part 101 and the fifth arc-shaped sliding matching part 201 slidingly matching and the sixth arc-shaped sliding part 202 and the sixth arc-shaped sliding matching part 120, the fifth arc-shaped sliding part 101 and the fifth arc-shaped sliding matching part 201 slide relatively along the arc-shaped trajectory to achieve relative rotation, and the sixth arc-shaped sliding part 202 and the sixth arc-shaped sliding matching part 102 slide relatively along the arc-shaped trajectory to achieve relative rotation. The fifth arc-shaped sliding part 101 and the fifth arc-shaped sliding matching part 201 are both arc-shaped structures, the fifth arc-shaped sliding part 101 is a protruding structure with an arc shape, and the protruding structure is provided with an arc-shaped surface, and the fifth arc-shaped sliding matching part 201 is an arc-shaped sliding groove, and the sliding groove is provided with an arc-shaped surface that cooperates with the sliding of the arc-shaped protrusion. Similarly, the sixth arc-shaped sliding portion 202 and the sixth arc-shaped sliding matching portion are also arc-shaped structures, and the specific structure is not repeated here, as long as the two can contact and match with each other in a relative sliding manner along an arc-shaped trajectory.

[0088] The two fifth arc-shaped sliding parts 101 and the first swing arm 10 can be an integral structure formed in one piece, or they can be formed separately and fixedly connected. The sixth arc-shaped sliding matching part 102 and the first swing arm 10 can be an integral structure formed in one piece, or they can be formed separately and fixedly connected. Similarly, the two fifth arc-shaped sliding matching parts 201 and the second swing arm 20 can be an integral structure formed in one piece, or they can be formed separately and fixedly connected. The sixth arc-shaped sliding part 202 and the second swing arm 20 can be an integral structure formed in one piece, or they can be formed separately and fixedly connected.

[0089] The first swing arm 10 and the second swing arm 20 located on both sides of the base 210 can rotate relative to each other based on the base 210, so that the hinge mechanism 200 can be switched between the unfolded state and the folded state. When the hinge mechanism 200 is applied to the electronic device 100, as the electronic device 100 is switched between the unfolded state and the folded state, the hinge mechanism 200 is also switched between the unfolded state and the folded state synchronously.

[0090] Please refer to this Fig. 9When the hinge mechanism 200 rotates from the folded state to the unfolded state, the second swing arms 20 located on both sides of the base 210 rotate away from each other, the second swing arms 20 located on both sides of the base 210 drive the first swing arm 10 to rotate relative to the base 210, and the first swing arms 10 located on both sides of the base 210 also rotate away from each other. At the same time, the two fifth arc-shaped sliding parts 101 slide in the arc-shaped sliding grooves formed by the two fifth arc-shaped sliding matching parts 201, and the sixth arc-shaped sliding part 202 slides in the groove formed by the sixth arc-shaped sliding matching part 102, so that the first swing arm 10 and the second swing arm 20 rotate relative to each other, and the assembly formed by the first swing arm 10 and the second swing arm 20 rotates away from the base 210.

[0091] According to the above description, the hinge mechanism 200 provided in the embodiment of the present application can be regarded as being rotationally connected to the second swing arm 20 by a virtual axis, because the first swing arm 10 and the second swing arm 20 are rotationally connected by two fifth arc-shaped sliding parts 101 and two fifth arc-shaped sliding matching parts 201 and the sixth arc-shaped sliding part 202 and the sixth arc-shaped sliding matching part 102. When the hinge mechanism 200 is converted between the unfolded state and the folded state, the angle at which the first swing arm 10 rotates relative to the base 210 and the angle at which the second swing arm 20 rotates relative to the base 210 may be different. Therefore, when the hinge mechanism 200 is applied to the terminal device 100, in the process of the terminal device 100 being converted from the unfolded state to the folded state, the angle at which the first swing arm 10 rotates relative to the base 210 can be designed as needed, and does not need to be the same as the angle at which the second swing arm 20 rotates relative to the base 210. The possibility of interference between the first swing arm and the folding screen of the terminal device when the terminal device is in a folded state can be reduced, which is conducive to further miniaturization of the size of the hinge mechanism, thereby facilitating a lightweight design of the terminal device.

[0092] In some embodiments, see Figures 10 to 12 One of the two fifth arc-shaped sliding parts 101 and the two fifth arc-shaped sliding matching parts 201 is an arc-shaped protrusion, and the other is an arc-shaped sliding groove matching with the arc-shaped protrusion. One of the third arc-shaped sliding part 202 and the third arc-shaped sliding matching part 102 is an arc-shaped protrusion, and the other is a sliding groove matching with the arc-shaped protrusion. Figures 10 to 12That is, it is exemplarily shown that the two fifth arc-shaped sliding parts 101 are arc-shaped protrusions, the sixth arc-shaped sliding part 202 is an arc-shaped protrusion, the two fifth arc-shaped sliding matching parts 201 are arc-shaped grooves, and the sixth arc-shaped sliding matching part 102 is an arc-shaped groove. Of course, the two can also be swapped, that is, the two fifth arc-shaped sliding parts 101 are arc-shaped grooves, the sixth sliding part 202 is an arc-shaped groove, the two fifth arc-shaped sliding matching parts 201 are arc-shaped protrusions, and the sixth arc-shaped sliding matching part 102 is an arc-shaped protrusion. The two fifth arc-shaped sliding parts 101 of the first swing arm 10 are in surface contact with the two fifth arc-shaped sliding matching parts 201 of the second swing arm 20, and the third arc-shaped sliding matching part 102 of the first swing arm 10 is in surface contact with the third arc-shaped sliding part 202 of the second swing arm 20. The arc-shaped protrusion can slide along the arc-shaped slide groove inside the arc-shaped slide groove and contact the groove wall surface of the arc-shaped slide groove.

[0093] It can be understood that the arc-shaped protrusion and the arc-shaped groove are slidably matched, and the two are in surface contact, which is beneficial to improving the stability and reliability of the relative sliding cooperation between the fifth arc-shaped sliding part 101 and the fifth arc-shaped sliding matching part 201 and the relative sliding cooperation between the sixth arc-shaped sliding part 102 and the sixth arc-shaped sliding matching part 202 compared to point contact and line contact, thereby improving the stability of the rotational cooperation between the first swing arm 10 and the second swing arm 20.

[0094] Optionally, the two fifth arc-shaped sliding portions 101 are arc-shaped protrusions, the two fifth arc-shaped sliding matching portions 201 are arc-shaped sliding grooves, the sixth arc-shaped sliding portion 202 is an arc-shaped protrusion, the sixth arc-shaped sliding matching portion 102 is an arc-shaped sliding groove, the arc-shaped sliding groove forms an opening on the upper surface of the swing arm, and the arc-shaped protrusion slides on the arc-shaped sliding groove, which is conducive to reducing the overall thickness dimension formed by the superposition and matching of the first swing arm 10 and the second swing arm 20. The upper surface of the second swing arm 20 refers to the side surface of the second swing arm 20 facing the folding screen 300.

[0095] It should be noted that the cooperation between the two fifth arc-shaped sliding parts 101 and the two fifth arc-shaped sliding fittings 201 and the cooperation between the sixth arc-shaped sliding part 202 and the sixth arc-shaped sliding fitting part 102 is not limited to the cooperation between the arc-shaped protrusion and the arc-shaped sliding groove.

[0096] Optionally, in some other embodiments, one of the two fifth arc-shaped sliding parts 101 and the two fifth arc-shaped sliding matching parts 201 may be an arc-shaped slot, and the other may include a plurality of sub-sliding parts, and the sixth arc-shaped sliding part 202 and the sixth arc-shaped sliding matching part 102 may be an arc-shaped slot, and the other may include a plurality of sub-sliding parts, wherein the sub-sliding part is a protrusion that matches the arc-shaped slot, but is not limited thereto. Each sub-sliding part is slidably arranged in the arc-shaped slot, and the sub-sliding part and the slot wall of the arc-shaped slot may be in point contact, line contact or surface contact, which can also realize that the fifth arc-shaped sliding part 101 and the fifth arc-shaped sliding matching part 201 slide relative to each other along the arc-shaped track.

[0097] The first swing arm 10 and the second swing arm 20 may be various types of swing arms, for example, they may be synchronous swing arms or main swing arms.

[0098] Please continue reading Figures 13 to 15 , Fig.13 This is a schematic diagram of the structure of the swing arm assembly and the door panel assembly in some embodiments of the present application; Fig.14 for Fig.13 Exploded diagram of the connection between the middle swing arm assembly and the door panel assembly. Fig.15 Schematic diagram of the shaft structure of some embodiments of the present application.

[0099] In some embodiments, the door panel assembly 340 is respectively disposed on both sides of the base 210 , wherein one end of the door panel assembly 340 located on one side of the base 210 is rotatably connected to the swing arm assembly 120 .

[0100] Specifically, in some embodiments, Fig.13 As described above, each door panel assembly 340 located on both sides of the base 210 includes a connecting member 30, and each connecting member 30 is respectively arranged on both sides of the base 210. In the swing arm assembly 120 and the connecting member 30 located on the same side of the base 210, the swing arm assembly 120 is rotatably connected to the connecting member 30.

[0101] like Fig.14 As shown, in the swing arm assembly 120 and the connecting member 30 located on the same side of the base 210, two first arc-shaped sliding parts 203 and a second arc-shaped sliding fitting part 204 are provided at one end of the swing arm assembly 120 close to the connecting member 30. The two first arc-shaped sliding parts 203 are respectively located on opposite sides of the second arc-shaped sliding fitting part 204, and are arranged side by side with the second arc-shaped sliding fitting part 204 along the length direction of the base 210.

[0102] Two first arc-shaped sliding fitting parts 301 and a second arc-shaped sliding part 302 are provided on one side of the connecting member 30 close to the swing arm assembly 120. The two first arc-shaped sliding fitting parts 301 are respectively located on the opposite sides of the second arc-shaped sliding part 204, and on the opposite sides of the second arc-shaped sliding part 302, and are arranged side by side on the second arc-shaped sliding part 302 along the length direction of the connecting member.

[0103] The arcuate surfaces of the two first arcuate sliding parts 203 on the swing arm assembly 120 overlap the inner wall surfaces of the two first arcuate sliding fitting parts 301 on the connecting member 30, so that the two arcuate sliding parts 203 on the swing arm assembly 120 are slidably matched with the two arcuate sliding fitting parts 301 on the connecting member 30. The second arcuate sliding part 302 on the connecting member 30 overlaps the inner wall surface of the second arcuate sliding fitting part 204 of the swing arm assembly 120, so that the second arcuate sliding fitting part 204 on the swing arm assembly 120 is slidably matched with the second arcuate sliding part 302 on the connecting member 30.

[0104] It can be understood that the two first circular arc sliding fitting parts 301 can allow the two first circular arc sliding parts 203 to slide thereon, and the second circular arc sliding fitting part 204 can allow the second circular arc sliding part 302 to slide, and through the sliding fit between the two first circular arc sliding parts 203 and the two first circular arc sliding fitting parts 301 and the sliding fit between one first circular arc sliding part 302 and one first circular arc sliding fitting part 204, the swing arm assembly 120 is rotatably connected to the connecting member 30.

[0105] By providing two first arc-shaped sliding parts 203 and one second arc-shaped sliding fitting part 204 on the swing arm assembly 120 and providing two first arc-shaped sliding fitting parts 301 and one second arc-shaped sliding part 302 on the connecting member 30, the sliding trajectory of the swing arm assembly 120 and the connecting member 30 can be jointly defined by the first arc-shaped sliding part 203 and the first arc-shaped sliding fitting part 301 and the second arc-shaped sliding part 302 and the second arc-shaped sliding fitting part 204. On the one hand, the sliding trajectory of the swing arm assembly 120 and the connecting member 30 is jointly defined by two first arc-shaped sliding fitting parts 301 and one second arc-shaped sliding fitting part 204, which can reduce the precision requirements for the first arc-shaped sliding fitting part 301 and the second arc-shaped sliding fitting part 204, thereby reducing the processing difficulty and processing cost of the connecting member and the swing arm. On the other hand, the sliding trajectory of the swing arm assembly 120 and the connecting member 30 is jointly defined by two first arc-shaped sliding fitting parts 301 and one second arc-shaped sliding fitting part 204, so that the first arc-shaped sliding fitting part 301 and the second arc-shaped sliding part 301 and the first arc-shaped sliding part 203 and the second arc-shaped sliding fitting part 204 are arranged in a distributed manner. The distributed arrangement of multiple arc-shaped sliding fitting parts and arc-shaped sliding parts can increase the overlap amount between the swing arm assembly 120 and the connecting member 30, increase the connection strength between the swing arm assembly 120 and the connecting member 30, make the swing arm assembly 20 and the connecting member 30 not easy to fall out when sliding relative to each other, and have good reliability.

[0106] It can be understood that the connection members 30 are respectively arranged on both sides of the base 210, which means that the connection members 30 are arranged on both sides of the base 210, but the number of the connection members 30 on each side can be one or more, and the number of the connection members 30 on both sides of the base 210 can be the same or different. Optionally, the connection members 30 on both sides of the base 210 can be arranged relative to each other, that is, they are approximately at the same position in the length direction of the base 210. Fig.13 Of course, in some other embodiments, the connectors 30 on both sides of the base 210 may not be arranged opposite to each other, that is, they may be staggered along the length direction of the base 210 .

[0107] It can be understood that the swing arm assembly 120 and the connecting member 30 located on the same side of the base 210 are connected to each other by slidingly matching the two first arc-shaped sliding parts 203 with the two first arc-shaped sliding matching parts 301 and slidingly matching the second arc-shaped sliding part 302 with the second arc-shaped sliding matching part 204. Therefore, the two first arc-shaped sliding parts 203 and the two first arc-shaped sliding matching parts 301 slide relatively along the arc-shaped trajectory to achieve relative rotation, and the second arc-shaped sliding part 302 and the second arc-shaped sliding matching part 204 slide relatively along the arc-shaped trajectory to achieve relative rotation. The two first arc-shaped sliding parts 203 and the two first arc-shaped sliding matching parts 301 are both arc-shaped structures, and the second arc-shaped sliding part 302 and the second arc-shaped sliding matching part 204 are both arc-shaped structures, and various forms of arc-shaped structures can also be used, as long as the two can slide relatively along the arc-shaped trajectory to contact and match, and its possible structure can refer to the above embodiment. The two first arc-shaped sliding parts 203 and the second arc-shaped sliding matching parts 204 can be an integral structure formed as one piece with the swing arm assembly 120, or they can be formed separately and fixedly connected; similarly, the two first arc-shaped sliding matching parts 302 and the second arc-shaped sliding parts 302 can be an integral structure formed as one piece with the connecting member 30, or they can be formed separately and fixedly connected.

[0108] The connecting members 30 located on both sides of the base 210 can rotate relative to the base 210, so that the hinge mechanism 200 is converted between the unfolded state and the folded state. When the hinge mechanism 200 is converted from the unfolded state to the folded state, the connecting members 30 located on both sides of the base 210 are relatively close to each other and rotated, and the connecting members 30 drive the swing arm assembly 120 to rotate relative to the base 210, and the swing arm assembly 120 located on both sides of the base 210 are also relatively close to each other and rotated. At the same time, the first arc-shaped sliding portion 203 and the first arc-shaped sliding matching portion 301 slide relative to each other, so that the connecting member 30 and the swing arm assembly 120 are relatively rotated.

[0109] When the hinge mechanism 200 is converted from the folded state to the unfolded state, the connecting parts 30 located on both sides of the base 210 rotate relatively away from each other, and the connecting parts 30 drive the swing arm assembly 120 to rotate relative to the base 210. The swing arm assembly 120 located on both sides of the base 210 also rotate relatively away from each other. At the same time, the first arc-shaped sliding portion 203 and the first arc-shaped sliding matching portion 301 slide relative to each other to make the connecting part 30 and the swing arm assembly 120 rotate relative to each other. The connecting part 30 moves roughly toward the base 210 and close to the swing arm assembly 120, which can be regarded as a shortening of the length of the assembly formed by the connecting part 30 and the swing arm assembly 120.

[0110] Please continue reading Fig.14One of the first arc-shaped sliding portion 203 and the first arc-shaped sliding matching portion 301 is an arc-shaped protrusion, and the other is an arc-shaped sliding groove that slides with the arc-shaped protrusion; one of the second arc-shaped sliding portion 302 and the second arc-shaped sliding matching portion 204 is an arc-shaped protrusion, and the other is an arc-shaped sliding groove that slides with the arc-shaped protrusion. Fig.14 In the figure, the first arc-shaped sliding part 203 is an arc-shaped protrusion, the first arc-shaped sliding matching part 301 is an arc-shaped sliding groove, the second arc-shaped sliding part 302 is an arc-shaped protrusion, and the second arc-shaped sliding matching part 204 is an arc-shaped sliding groove. Of course, the two can also be exchanged, that is, the first arc-shaped sliding part 203 is an arc-shaped sliding groove, the first arc-shaped sliding matching part 301 is an arc-shaped protrusion, the second arc-shaped sliding part 302 is an arc-shaped sliding groove, and the second arc-shaped sliding matching part 204 is a slide rail. The two first arc-shaped sliding parts 203 are in surface contact with the two first arc-shaped sliding matching parts 301, and the second arc-shaped sliding part 302 is in surface contact with the second arc-shaped sliding matching part 204. The arc-shaped slide rail can slide inside the arc-shaped slide groove along the groove wall of the arc-shaped slide groove and contact the groove wall surface of the arc-shaped slide groove.

[0111] It can be understood that the arc-shaped slide rail can be an arc-shaped protrusion in various structural forms, but is not limited thereto, as long as it can slide with the arc-shaped slide groove along an arc-shaped track.

[0112] Such arrangement, since the arc-shaped protrusion and the arc-shaped groove are slidably matched and the two are in surface contact, is beneficial to improving the stability and reliability of the relative sliding between the first arc-shaped sliding part 203 and the first arc-shaped sliding matching part 301 and the relative sliding between the second arc-shaped sliding part 302 and the second arc-shaped sliding matching part 204 compared to point contact and line contact, thereby improving the stability of the rotational cooperation between the swing arm assembly 120 and the connecting member 30.

[0113] Optionally, see Fig.14 The two first arc-shaped sliding fitting parts 301 and the second arc-shaped sliding fitting parts 204 are arc-shaped sliding grooves, and the arc-shaped sliding grooves can form an opening at one end of the swing arm assembly 120 and one side of the connecting member 30 to avoid the swing arm assembly 20 through the opening, which is beneficial to reducing the overall thickness dimension formed by the overlapping and matching of the swing arm assembly 120 and the connecting member 30.

[0114] Optionally, in some other embodiments, the two first circular arc sliding parts 203 and the two first circular arc sliding fitting parts 301 can both be circular arc protrusions or circular arc slide rails, the second circular arc sliding part 302 and the second circular arc sliding fitting part 204 can both be circular arc protrusions or circular arc slide rails, the outer walls of the circular arc sliding parts and the circular arc sliding fitting parts include circular arc surfaces, the circular arc surfaces of the two first circular arc sliding parts 203 are slidably fitted with the circular arc surfaces of the two first circular arc sliding fitting parts 301 and are in surface contact, and the two can also slide along the circular arc trajectory to enable the swing arm assembly 120 to be rotatably connected with the connecting member 30.

[0115] Optionally, in some other embodiments, one of the first arc-shaped sliding part 203 and the first arc-shaped sliding fitting part 301 may be an arc-shaped slot, and the other may include a plurality of sub-sliding parts; one of the second arc-shaped sliding part 302 and the second arc-shaped sliding fitting part 204 may be an arc-shaped slot, and the other may also include a plurality of sub-sliding parts. Each sub-sliding part is slidably arranged in the arc-shaped slot, and the slot wall of the sub-sliding part and the arc-shaped slot may be in point contact, line contact or surface contact, which can also realize that the first arc-shaped sliding part 203 and the first arc-shaped sliding fitting part 301 slide relative to each other along the arc-shaped track, and the second arc-shaped sliding part 302 and the second arc-shaped sliding fitting part 204 slide relative to each other along the arc-shaped track.

[0116] Please continue to refer to Figures 16 to 18 , Fig.16 This is a schematic diagram of the shaft structure of some embodiments of the present application; Fig.17 It is a structural schematic diagram of the connecting piece and the door panel; Fig.18 It is a schematic diagram of the coordination between the connector and the door panel.

[0117] Specifically, in some embodiments, the door panel assembly 340 includes a connector 30 and a door panel 40. Specifically, as shown in FIG. Fig.16 As shown, the door panel assembly 340 includes a connecting member 30 and a door panel 40, wherein the connecting member 30 located on the same side of the base 210 is rotatably connected to the door panel 40, and each door panel 40 is respectively arranged on both sides of the base 210. Among the connecting members 30 and the door panels 40 located on the same side of the base 210, a third arc-shaped sliding portion 303 and a fourth arc-shaped sliding fitting portion 304 are provided on the side of the connecting member 30 close to the door panel 40, and the third arc-shaped sliding portion 303 and the fourth arc-shaped sliding fitting portion 304 are arranged side by side along the length direction of the connecting member.

[0118] A third arc-shaped sliding fitting portion 401 and a fourth arc-shaped sliding portion 402 are provided on one side of the door panel 40 close to the connecting member 30 . The third arc-shaped sliding fitting portion 401 and the fourth arc-shaped sliding portion 402 are arranged side by side along the length direction of the door panel 40 .

[0119] The third arc-shaped sliding portion 303 on the connecting member 30 is disposed in the third arc-shaped sliding fitting portion 401 on the door panel 40, so that the third arc-shaped sliding portion 303 on the connecting member 30 is slidably fitted with the third sliding fitting portion 401 on the door panel 40. The fourth arc-shaped sliding portion 402 on the door panel 40 is disposed in the fourth sliding fitting portion 304 on the connecting member 30, so that the fourth arc-shaped sliding portion 402 is slidably fitted with the fourth arc-shaped sliding fitting portion 304.

[0120] It can be understood that the third arc-shaped sliding fitting portion 401 can allow the third arc-shaped sliding portion 303 to slide thereon, and the fourth arc-shaped sliding fitting portion 304 can allow the fourth arc-shaped sliding portion 402 to slide thereon. By arranging the third sliding portion 303 and the fourth sliding fitting portion 304 on the connecting member 30 and arranging the third sliding fitting portion 401 and the fourth sliding portion 402 on the door panel 40 to jointly define the sliding trajectory of the connecting member 30 and the door panel 40, the requirements for the connection accuracy between the connecting member 30 and the door panel 40 can be reduced, thereby reducing the processing difficulty and processing cost of the connecting member and the door panel. On the other hand, the third arc-shaped sliding part 303 and the third sliding matching part 401 and the fourth sliding part 402 and the fourth sliding matching part 304 are distributedly arranged. The multiple arc-shaped sliding parts and arc-shaped sliding matching parts arranged separately can increase the overlap between the connecting member 30 and the door panel 40, increase the connection strength between the connecting member 30 and the door panel, make the connecting member 30 and the door panel 40 not easy to fall off during relative rotation, and have good reliability.

[0121] It can be understood that the third arc-shaped sliding part 303 and the third arc-shaped sliding matching part 401 slide relative to each other along the arc-shaped trajectory to achieve relative rotation, and the fourth arc-shaped sliding part 402 and the fourth arc-shaped sliding matching part slide relative to each other along the arc-shaped trajectory to achieve relative rotation. The third arc-shaped sliding part 303 and the third arc-shaped sliding matching part 401 are both arc-shaped structures, and the fourth arc-shaped sliding part 402 and the fourth arc-shaped sliding matching part 304 are both arc-shaped structures, and can also be various forms of arc-shaped structures, as long as the two can slide relative to each other along the arc-shaped trajectory. The third arc-shaped sliding part 303 and the fourth arc-shaped sliding matching part 304 can be an integral structure formed integrally with the connecting member 30, or they can be formed separately and fixedly connected; similarly, the third arc-shaped sliding matching part 401 and the fourth arc-shaped sliding part 402 can be an integral structure formed integrally with the door panel 40, or they can be formed separately and fixedly connected.

[0122] Optionally, one of the third arc-shaped sliding portion 303 and the third arc-shaped sliding fitting portion 401 is an arc-shaped protrusion, and the other is an arc-shaped sliding groove that slides with the arc-shaped protrusion; one of the fourth arc-shaped sliding portion 402 and the fourth arc-shaped sliding fitting portion 304 is an arc-shaped protrusion, and the other is an arc-shaped sliding groove that slides with the arc-shaped protrusion. Fig.17 and Fig.18 The third arc-shaped sliding part 303 and the fourth arc-shaped sliding part 402 are arc-shaped protrusions, and the third arc-shaped sliding matching part 401 and the fourth arc-shaped sliding matching part 304 are arc-shaped sliding grooves. Of course, the two can also be exchanged, that is, the third arc-shaped sliding part 303 and the fourth arc-shaped sliding part 402 are arc-shaped sliding grooves, and the third arc-shaped sliding matching part 401 and the fourth arc-shaped sliding matching part 304 are arc-shaped protrusions. The third arc-shaped sliding part 303 is in surface contact with the third arc-shaped sliding matching part 401, and the fourth arc-shaped sliding part 402 and the fourth arc-shaped sliding matching part 304 are arc-shaped slide rails, that is, they can slide along the groove wall of the arc-shaped sliding groove inside the arc-shaped sliding groove and contact the groove wall surface of the arc-shaped sliding groove.

[0123] Such arrangement, since the arc-shaped slide rail and the arc-shaped slide groove are slidably matched and the two are in surface contact, compared with point contact and line contact, it is beneficial to improve the stability and reliability of the relative sliding between the third arc-shaped sliding part 303 and the third arc-shaped sliding matching part 401 and the fourth arc-shaped sliding part 402 and the fourth arc-shaped sliding matching part 304, thereby improving the stability of the rotational matching between the connecting member 30 and the door panel 40.

[0124] Optionally, the third arc-shaped sliding fitting portion 401 and the fourth arc-shaped sliding fitting portion 304 are arc-shaped slide grooves, which can form an opening on one side of the connecting member 30 and the door panel 40 to assemble the connecting member 30 and the door panel 40 through the opening, thereby facilitating reducing the thickness dimension of the connecting member 30 and the door panel 40 formed by overlapping and fitting together.

[0125] Optionally, in some other embodiments, one of the third arc-shaped sliding part 303 and the third arc-shaped sliding matching part 401 may be an arc-shaped slot, and the other may include a plurality of sub-sliding parts; one of the fourth arc-shaped sliding part 402 and the fourth arc-shaped sliding matching part 304 may be an arc-shaped slot, and the other may include a plurality of sub-sliding parts. Each sub-sliding part is slidably arranged in the arc-shaped slot, and the sub-sliding part and the slot wall of the arc-shaped slot may be in point contact, line contact or surface contact, and the third arc-shaped sliding part 303 and the third arc-shaped sliding matching part 401 can also slide relative to each other along an arc-shaped trajectory, and the fourth arc-shaped sliding part 402 and the fourth arc-shaped sliding matching part 304 can slide relative to each other along an arc-shaped trajectory.

[0126] In some embodiments, the swing arm assembly 120 may further include a first swing arm 10, a second swing arm 20 and a connecting member 30, and the door panel assembly 340 includes a door panel 40. The connection mode between the swing arm assembly 120 and the door panel assembly 340, i.e., the connection mode between the connecting member 30 and the door panel 40, may be specifically understood with reference to the connection mode between the connecting member 30 and the door panel 40 in the above embodiment.

[0127] Continue to refer Figures 19 to 22 , Fig.19 An exploded schematic diagram of a rotating shaft in some embodiments of the present application; Fig. 20 It is a schematic diagram of the connection between the swing arm assembly and the door panel assembly; Fig.21 It is an exploded schematic diagram of the swing arm assembly and the door panel assembly; Fig. 22 This is a schematic diagram of the folding axis of some embodiments of the present application.

[0128] In some embodiments, the swing arm assembly 120 in the rotating shaft mechanism 200 may also include only one swing arm, such as Fig.19 As shown, the shaft mechanism 200 includes a base 210, at least two swing arm assemblies 120 and at least two door panel assemblies 340, wherein the swing arm assembly 120 is rotatably connected to the base 210, and the specific connection form is not limited. The specific connection form can refer to the connection mode between the swing arm assembly and the base 210 in the above embodiment, as long as the swing arm assembly 120 and the base 210 can be rotatably connected. The swing arm assembly 120 located on the same side of the base 210 is rotatably connected to the door panel assembly 340.

[0129] Specifically, Figure 20 to Figure 21 As shown, in the swing arm assembly 120 and the door panel assembly 340 located on the same side of the base 210, one end of the swing arm assembly 120 close to the door panel assembly 340 is provided with two first arc-shaped sliding parts 203 and a second arc-shaped sliding fitting part 204. The two first arc-shaped sliding parts 203 are respectively located on opposite sides of the second arc-shaped sliding fitting part 204, and are arranged side by side on the second arc-shaped sliding fitting part 204 along the length direction of the base 210.

[0130] Two first arc-shaped sliding fitting parts 301 and a second arc-shaped sliding part 302 are provided on one side of the door panel assembly 340 close to the swing arm assembly 120. The two first arc-shaped sliding fitting parts 301 are respectively located on the opposite sides of the second arc-shaped sliding part 204, and on the opposite sides of the second arc-shaped sliding part 302, and are arranged side by side along the length direction of the connecting part at the second arc-shaped demarcating part 302.

[0131] The two first arc-shaped sliding parts 203 on the swing arm assembly 120 overlap the two first arc-shaped sliding fitting parts 301 on the door panel assembly 340, so that the two arc-shaped sliding parts 203 on the swing arm assembly 120 slide and fit with the two arc-shaped sliding fitting parts 301 on the door panel assembly 340. The second arc-shaped sliding part 302 on the door panel assembly 340 is placed in the second arc-shaped sliding fitting part 204 on the swing arm assembly 120, so that the second arc-shaped sliding fitting part 204 on the swing arm assembly 120 slides and fits with the second arc-shaped sliding part 302 on the door panel assembly 340.

[0132] It can be understood that the two first arc-shaped sliding fitting parts 301 can allow the two first arc-shaped sliding parts 203 to slide thereon, and the second arc-shaped sliding fitting part 204 can allow the second arc-shaped sliding part 302 to slide, and through the sliding fit between the two first arc-shaped sliding parts 203 and the two second arc-shaped sliding fitting parts 301 and the sliding fit between one second arc-shaped sliding part 302 and one second arc-shaped sliding fitting part 204, the swing arm assembly 10 and the door panel assembly 340 are rotatably connected.

[0133] By providing two first arc-shaped sliding parts 203 and one second arc-shaped sliding fitting part 204 on the swing arm assembly 120 and providing two first arc-shaped sliding fitting parts 301 and one second arc-shaped sliding part 302 on the door panel assembly 340, the sliding trajectories of the swing arm assembly 120 and the door panel assembly 340 can be jointly defined by the first arc-shaped sliding part 203 and the first arc-shaped sliding fitting part 301 and the second arc-shaped sliding part 302 and the second arc-shaped sliding fitting part 204. On the one hand, the sliding trajectories of the first swing arm 120 and the door panel assembly 340 are jointly defined by two first arc-shaped sliding fitting parts 301 and one second arc-shaped sliding fitting part 204, which can reduce the precision requirements for the first arc-shaped sliding fitting part 301 and the second arc-shaped sliding fitting part 204, thereby reducing the processing difficulty and processing cost of the door panel assembly 340 and the swing arm assembly 120. On the other hand, the sliding trajectory of the swing arm assembly 120 and the door panel assembly 340 is jointly defined by two first arc-shaped sliding fitting parts 301 and one second arc-shaped sliding fitting part 204, so that the first arc-shaped sliding fitting part 301 and the second arc-shaped sliding part 301 and the first arc-shaped sliding part 203 and the second arc-shaped sliding fitting part 204 are distributedly arranged. The distributed arrangement of multiple arc-shaped sliding fitting parts and arc-shaped sliding parts can increase the overlap amount between the swing arm assembly 120 and the door panel assembly 340, increase the connection strength between the first swing arm assembly 120 and the door panel assembly 340, make the swing arm assembly 120 and the door panel assembly 340 not easy to fall out when sliding relative to each other, and have good reliability.
