Description

Technical Field

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

[0002] The rotating mechanism has become an essential core component of foldable electronic devices. Among them, the shaft cover and support plate are important parts of the rotating mechanism, and the reliability of their fixed connection affects the overall reliability of the device. However, with the gradual development of foldable electronic devices, their size is becoming smaller and smaller, and the rotating mechanism is also becoming thinner and narrower, making the space for the shaft cover and support plate very limited. This results in very limited space reserved for the connecting parts that connect the shaft cover and support plate, leading to lower reliability of the fixed connection between the shaft cover and support plate. Summary of the Invention

[0003] This application provides a rotating mechanism and a foldable electronic device that can ensure a reliable connection between the support plate and the shaft cover.

[0004] This application provides a rotating mechanism, including: a shaft cover, a support plate, and a connecting member. The shaft cover includes a body portion and two first mounting portions. The body portion includes a mounting surface extending along the length direction of the rotating mechanism. Along the length direction of the rotating mechanism, the two first mounting portions protrude from both ends of the mounting surface, and are spaced apart from each other. The support plate has two second mounting portions located at opposite ends of the support plate along the length direction of the rotating mechanism. Along the thickness direction of the rotating mechanism, the support plate is stacked on the support surface of the body portion. The support plate is located within the gap between the two first mounting portions, and the two first mounting portions abut against the two second mounting portions respectively. Along the length direction of the rotating mechanism, one end of the connecting member is fixed to a first mounting portion, and the other end of the connecting member is fixed to a second mounting portion.

[0005] It is understandable that the rotating mechanism is used in foldable electronic devices, and the surface of the support plate opposite to the shaft cover is used to support the display screen of the foldable electronic device.

[0006] In related technologies, the support plate and the shaft cover are fixedly connected by screws. The shank of the screw is fixed to the shaft cover, and the nut of the screw is fixed to the support plate, with the nut protruding from the surface of the support plate away from the shaft cover, i.e., facing the display screen of the foldable electronic device. In this case, the direction of the fixing force between the shaft cover and the support plate is parallel to the thickness direction. However, as the rotating mechanism becomes increasingly thinner, the space in the thickness direction becomes very limited, causing the nut to interfere with the display screen. If the foldable electronic device is dropped, the nut will impact the display screen, causing damage. Furthermore, the limited Z-axis space can only accommodate screws with short shanks, resulting in short locking teeth at the shank, ultimately leading to insufficient reliability of the connection between the shaft cover and the support plate. Additionally, because the shaft cover is thin, the distance between the bottom of the screw and the outer surface of the shaft cover is also very small, easily causing dents on the outer surface of the shaft cover.

[0007] In this application, the first mounting part and the second mounting part are arranged along the length direction and fixedly connected by a connector. At this time, the fixing force between the support plate and the shaft cover is parallel to the length direction. This fixing method mainly occupies space in the length direction, with less space requirement in the thickness direction. It ensures a reliable connection between the support plate and the shaft cover without interfering with the display screen, preventing damage to the display screen, and also preventing dents on the outer surface of the shaft cover, increasing the appearance and refinement of the shaft cover.

[0008] In some embodiments, one of the first mounting portion and the second mounting portion is provided with a locking hole, and the other is provided with an assembly structure. One end of the connector is fixed to the assembly structure, and the other end of the connector is fixed to the locking hole.

[0009] By setting a locking hole and allowing the connecting piece to extend into and be fixed within the locking hole, the reliability of fixing the shaft cover and support plate can be increased, as well as the structural compactness of the rotating mechanism can be improved.

[0010] In some embodiments, the wall surface of the connector and / or the locking hole is provided with an inclined surface so that the amount of interference between the connector and the wall surface of the locking hole gradually increases as the connector extends into the locking hole.

[0011] The above design can increase the reliability of the fasteners and the shaft cover.

[0012] In some embodiments, as the connector extends into the locking hole along the length of the rotating mechanism, the connector gradually moves from the opening of the locking hole toward the bottom surface of the locking hole, and the amount of interference between the connector and the hole wall of the locking hole gradually increases.

[0013] The interference between the connector and the locking hole gradually increases along the length of the rotating mechanism, which can increase the reliability of the connection between the shaft cover and the support plate. Furthermore, if the inclined surface is provided on the connector, the inclined surface causes the outer diameter of the connector to gradually increase. When assembling the shaft cover and the support plate, the end of the connector with the smaller outer diameter extends into the locking hole first, which facilitates the connector's insertion into the locking hole.

[0014] In some embodiments, after the connector extends into the locking hole along the length direction of the rotating mechanism, the connector moves along the width direction of the rotating mechanism, and the interference between the connector and the hole wall of the locking hole gradually increases.

[0015] That is, the connecting part first moves along the length of the rotating mechanism to extend into the locking hole, and then moves within the locking hole along the width of the rotating mechanism. At this time, the interference between the connecting part and the locking hole gradually increases, thereby increasing the connection reliability between the shaft cover and the support plate.

[0016] In some embodiments, the first mounting portion includes a first end face, and the second mounting portion includes a second end face, with the first and second end faces abutting each other along the length of the rotating mechanism. A locking hole is recessed in the first end face, and the assembly structure includes the second end face. Alternatively, the locking hole is recessed in the second end face, and the assembly structure includes the first end face.

[0017] The assembly structure can be either a first end face or a second end face, resulting in a simple structure that is easy to manufacture. Furthermore, if the assembly structure is a first end face, the connecting part can be integrally formed with the shaft cover. If the assembly structure is a second end face, the connecting part can be integrally formed with the support plate, eliminating the need for additional disassembly and reducing the number of parts in the rotating mechanism.

[0018] In some embodiments, the first mounting portion includes a first end face, and the second mounting portion includes a second end face, with the first and second end faces abutting each other along the length of the rotating mechanism. A locking hole is recessed in the first end face, and the second mounting portion has a mounting hole. Alternatively, the locking hole is recessed in the second end face, and the first mounting portion has a mounting hole.

[0019] The assembly structure includes mounting holes. In this configuration, one end of the connector extends into the locking hole, and the other end extends into the mounting hole, which increases the reliability of the connection between the shaft cover and the support plate, as well as the structural compactness of the rotating mechanism.

[0020] In some embodiments, the mounting hole is recessed in the second end face, and the assembly structure further includes a receiving groove recessed in the surface of the second mounting portion away from the shaft cover, the receiving groove communicating with the mounting hole. The connecting member passes through the mounting hole and extends into the receiving groove. The rotating mechanism also includes a stop member, which is fixed in the receiving groove, and along the length direction of the rotating mechanism, both ends of the stop member abut against the side surfaces of the connecting member and the receiving groove, respectively.

[0021] Using a stopper to abut the connector allows the connector to securely connect the support plate and the shaft cover, increasing assembly convenience and reliability of the support plate and shaft cover.

[0022] In some embodiments, the mounting hole is recessed in the second end face and penetrates the surface of the second mounting portion away from the shaft cover. There are two connecting members, one end of each connecting member is fixed to the locking hole, and the other end of each connecting member is fixed to the mounting hole. The rotating mechanism also includes a stop member, which is fixed within the mounting hole and, along the width direction of the rotating mechanism, is located between the two connecting members, with opposite sides of the stop member abutting against the two connecting members respectively.

[0023] Using a single abutment can abut against two connectors, allowing the connectors to securely connect the support plate and the shaft cover. This increases assembly convenience and the reliability of fixing the support plate and the shaft cover.

[0024] In some embodiments, the two connectors are a first connector and a second connector. The first connector includes a first connecting segment and a second connecting segment fixed at an included angle, and the second connector includes a third connecting segment and a fourth connecting segment fixed at an included angle. The mounting hole includes a first side surface and a second side surface. Along the width direction of the rotating mechanism, the first side surface and the second side surface are opposite each other. The first side surface has a first mounting groove recessed therein, and the second side surface has a second mounting groove recessed therein. The first connecting segment is fixed within the first mounting groove, and the second connecting segment extends into the locking hole. The third connecting segment is fixed within the second mounting groove, and the fourth connecting segment extends into the locking hole.

[0025] The above structure increases the reliability of the support plate and shaft cover fixing, while improving the structural compactness of the rotating mechanism.

[0026] In some embodiments, the top wall surface of the first connecting segment and / or the first mounting groove is provided with a first inclined surface, and the top wall surface of the third connecting segment and / or the second mounting groove is provided with a second inclined surface.

[0027] Along the width direction of the rotating mechanism, the abutment moves the first connecting section into the first mounting groove and the third connecting section into the second mounting groove. The first and third connecting sections move away from each other. The first inclined surface gradually increases the interference between the first connecting section and the groove wall of the first mounting groove, and the second inclined surface gradually increases the interference between the third connecting section and the groove wall of the second mounting groove. This gradual increase in interference makes the connection between the support plate and the shaft cover more stable and reliable.

[0028] In some embodiments, the top wall surface of the second connecting segment and / or the locking hole is provided with a third inclined surface, and the top wall surface of the fourth connecting segment and / or the locking hole is provided with a fourth inclined surface.

[0029] Along the length of the rotating mechanism, after the second and fourth connecting sections extend into the locking hole, the abutment causes the second and fourth connecting sections to move away from each other along the width of the rotating mechanism. The third inclined surface gradually increases the interference between the second connecting section and the wall of the locking hole, and the fourth inclined surface gradually increases the interference between the fourth connecting section and the wall of the locking hole. This gradual increase in interference makes the connection between the support plate and the shaft cover more stable and reliable.

[0030] In some embodiments, the connector includes a fixing part, which includes a first connector, a second connector, and a flexible body. The first connector and the second connector are respectively fixed to both sides of the flexible body. The first connector is fixed to the assembly structure, the second connector is fixed to the locking hole, and the flexible body has elastic deformation capability, allowing the second connector to extend into or retract from the locking hole.

[0031] When assembling the support plate and the shaft cover, the first connector is first fixed to the assembly structure. When the flexible body is in its natural state, the end of the second connector protrudes relative to the second mounting part. At this time, force is applied to the flexible body, causing it to deform. The flexible body then retracts the second connector until it aligns with the end of the second mounting part. Next, the support plate is stacked on the main body of the shaft cover. Then, the force applied to the flexible body is released, and the flexible body returns to its original position, causing the end of the second connector to protrude relative to the second mounting part. The second connector can then be inserted into the locking hole. By incorporating the flexible body, a reliable connection between the shaft cover and the support plate is ensured, while also increasing assembly convenience.

[0032] In some embodiments, the connector further includes an operating part with an operating ramp. A locking hole is provided in the first mounting part, and an assembly structure is provided in the second mounting part. The second mounting part has an operating hole that penetrates the second mounting part along the thickness direction of the rotating mechanism. The operating ramp and the operating hole are opposite each other along the thickness direction of the rotating mechanism.

[0033] When assembling the shaft cover and support plate, the connector is fixed to the second mounting part. At this time, the operating part and the operating hole are opposite each other, the operating ramp faces the operating hole, and the first connector of the fixing part protrudes from the end of the second mounting part. Next, an auxiliary tool with an inclined surface is inserted into the operating hole, so that the inclined surface of the auxiliary tool contacts the operating ramp. Then, the operating part is moved by the auxiliary tool, which causes the flexible body to deform. The flexible body causes the first connector to move, so that the first connector moves to at least a position flush with the end of the second mounting part. Then, the support plate is placed in the gap between the two first mounting parts, at which point the connector is located between the support plate and the shaft cover. Next, the auxiliary tool is removed from the operating hole. At this time, the flexible body resets, causing the first connector to reset as well. The first connector extends into the locking hole, thus fixing the support plate and the shaft cover together. That is, by setting the operating ramp, the ease of assembly can be increased.

[0034] In some embodiments, there are two fixing parts, with the flexible bodies of the two fixing parts respectively fixed to both sides of the operating part along the width direction of the rotating mechanism. Using two fixing parts to connect the support plate and the shaft cover can increase the reliability of the connection. When the flexible body is deformed by an auxiliary tool, the first connecting body of the two fixing parts can be moved simultaneously, increasing the ease of assembly.

[0035] There are two fixing parts, and correspondingly, two locking holes can be provided. The first connecting bodies of the two fixing parts are respectively fixed in the two locking holes. It can be understood that the two locking holes can be independent holes spaced apart from each other along the width direction of the rotating mechanism. Alternatively, the two locking holes can be connected along the width direction of the rotating mechanism, so that when the flexible body deforms, the two first connecting bodies can move simultaneously along the width and length directions of the rotating mechanism.

[0036] In some embodiments, the support plate can elastically deform along the length of the rotating mechanism so that the connector can extend into or retract from the locking hole.

[0037] When assembling the shaft cover and support plate, an external force can be used to deform the support plate, allowing the connecting piece to extend into the locking hole. Then, the external force is removed, and the first and second mounting parts abut against each other, fixing the shaft cover and support plate together with the connecting piece.

[0038] In some embodiments, a limiting part is also provided on the mounting surface. Along the length direction of the rotating mechanism, the limiting part and the first mounting part are spaced apart and opposite to each other, and a limiting groove is formed between the limiting part and the first mounting part. The second mounting part is disposed in the limiting groove.

[0039] The limiting groove can limit the second mounting part, increasing the reliability of the connection between the support plate and the shaft cover.

[0040] The second aspect of this application provides a foldable electronic device, including a first housing, a second housing, and a rotation mechanism according to any one of the first aspects of this application. The first housing and the second housing are respectively connected to opposite sides of the rotation mechanism, and the first housing and the second housing can be unfolded or folded relative to each other.

Detailed Implementation

[0079] The embodiments of this application are described below with reference to the accompanying drawings.

[0080] Please see Figure 1 and Figure 2 This application provides an electronic device; please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the foldable electronic device 1000 provided in the embodiments of this application in the first state. Figure 2 This is a schematic diagram of the structure of the foldable electronic device 1000 provided in the embodiments of this application in the second state.

[0081] Figure 1 The foldable electronic device 1000 shown is in a folded state. Figure 2The foldable electronic device 1000 shown is in the unfolded state. Figure 1 The foldable electronic device 1000 shown has a folding angle of approximately 0 degrees. Figure 2 The unfolding angle of the foldable electronic device 1000 shown is approximately 180 degrees. For ease of description, the width direction of the foldable electronic device 1000 is defined as the X direction, the length direction as the Y direction, and the thickness direction as the Z direction. The X, Y, and Z directions are all perpendicular to each other.

[0082] The foldable electronic device 1000 includes, but is not limited to, cellphones, notebook computers, tablet personal computers, personal digital assistants, wearable devices, or mobile devices. In this embodiment, a cellphone is used as an example of the foldable electronic device 1000 for illustration.

[0083] A foldable electronic device 1000 includes a main body 200 and a display screen 300, the display screen 300 being mounted on the main body 200. The display screen 300 can be a flexible screen, and the display screen includes a display surface and a mounting surface, which are disposed opposite to each other. The display surface is used to display text, images, and videos, etc. The display screen 300 includes a first display unit 310, a second display unit 320, and a third display unit 330. The third display unit 330 is located between the first display unit 310 and the second display unit 320.

[0084] Please see Figure 3 , Figure 3 yes Figure 2 The diagram shows the structural design of the main body of the foldable electronic device.

[0085] The main body 200 includes a first housing 210, a second housing 220, and a rotating mechanism 100. The first housing 210 has a first receiving cavity, and the second housing 220 has a second receiving cavity (not shown). The first and second receiving cavities are connected to form a receiving cavity. The rotating mechanism 100 is installed in the receiving cavity and is fixedly connected to the first housing 210 and the second housing 220 to realize a rotatable connection between the first housing 210 and the second housing 220. The first housing 210 and the second housing 220 can rotate relative to each other through the rotating mechanism 100, so that the main body 200 can switch between a folded state and an unfolded state.

[0086] The display screen 300 is mounted on the main body 200, and the mounting surface is fixedly connected to the main body 200. Specifically, the first housing 210 carries the first display unit 310, and the second housing 220 carries the second display unit 320. The rotating mechanism 100 is disposed opposite to the third display unit 330.

[0087] See Figure 2 and Figure 3 The first housing 210 and the second housing 220 rotate relative to each other via the rotating mechanism 100. When the foldable electronic device 1000 is in the unfolded state, the display screen 300 has a large display area, enabling the foldable electronic device 1000 to display and operate on a large screen, thus improving the user experience. (See also...) Figure 1 and Figure 3 When the foldable electronic device 1000 is in the folded state, the display screen 300 is located between the first housing 210 and the second housing 220. The first housing 210 and the second housing 220 protect the display surface of the display screen 300, which can greatly reduce the probability of the display screen 300 being damaged, and the overall size is reduced, making it easy to carry.

[0088] It should be noted that the directional terms such as "top," "bottom," "left," "right," "front," and "rear" used in the description of the foldable electronic device 1000 in this application are mainly based on the attached diagram of the foldable electronic device 1000. Figure 2 as well as Figure 4 The orientation of the device is described in the diagram, with the positive Z-axis direction as "top" or "up", the negative Z-axis direction as "bottom" or "down", the positive X-axis direction as "right", the negative X-axis direction as "left", the negative Y-axis direction as "back", and the positive Y-axis direction as "front". This does not constitute a limitation on the orientation of the foldable electronic device 1000 in actual application scenarios.

[0089] refer to Figure 3 The rotating mechanism 100 includes a support base 10, a fixing component 110, a main swing arm assembly 120, a synchronous swing arm assembly 130, and a damping component 140. Each of the main swing arm assembly 120, synchronous swing arm assembly 130, and damping component 140 can be one or more. For example, there are two main swing arm assemblies 120, synchronous swing arm assemblies 130, and damping components 140. Along the Y-axis, the two main swing arm assemblies 120 are located at both ends of the rotating mechanism 100, the two synchronous swing arm assemblies 130 are located between the two main swing arm assemblies 120, and the two damping components 140 are located between the two synchronous swing arm assemblies 130.

[0090] refer to Figure 4 and Figure 5 , Figure 4 yes Figure 3The schematic diagram shows the split structure of the bearing base 10 and the support plate 30 of the rotating mechanism 100 shown. Figure 5 yes Figure 3 The diagram shows a structure in which the bearing base 10 of the rotating mechanism 100 forms a receiving groove 11 with the shaft cover 20 and the support plate 30.

[0091] The support base 10 includes a shaft cover 20 and a support plate 30. Along the Z-axis, the support plate 30 and the shaft cover 20 are stacked and fixedly connected. A receiving groove 11 is formed between the support plate 30 and the shaft cover 20. The receiving groove 11 is used to accommodate a portion of the main swing arm assembly 120, a portion of the synchronous swing arm assembly 130, and the damping assembly 140. Specifically, the receiving groove 11 is formed between the bottom surface of the support plate 30 and the top surface of the shaft cover 20. The top surface of the support plate 30, i.e., the surface of the support plate 30 facing away from the shaft cover 20, is used to support the display screen 300. The bottom surface of the shaft cover 20, i.e., the surface of the shaft cover 20 facing away from the support plate 30, is the outer surface.

[0092] In some embodiments, reference is made to Figure 6 , Figure 6 yes Figure 3 The diagram shows a structural schematic of the rotating mechanism 100, where the bearing base 10's shaft cover 20 and support plate 30 are fixed together by screws. Specifically, the screw's axial direction is parallel to the Z-axis. The screw includes a nut and a shank fixed along the Z-axis. The shank is fixed to the shaft cover 20, and the nut is fixed to the support plate 30, with the nut protruding relative to the upper surface of the support plate 30. In this case, the direction of the fixing force between the shaft cover 20 and the support plate 30 is parallel to the Z-axis. However, as the rotating mechanism 100 becomes increasingly thinner, the space in the Z-axis direction becomes very limited, causing the nut to interfere with the display screen 300. If the foldable electronic device 1000 is dropped, the nut will impact the display screen 300, causing damage. Furthermore, the limited Z-axis space can only accommodate screws with shorter shanks, resulting in shorter locking teeth on the shank, ultimately leading to insufficient reliability of the connection between the shaft cover 20 and the support plate 30. In addition, because the shaft cover 20 is thin, the distance between the bottom of the screw and the outer surface of the shaft cover 20 is also very small, which can easily cause dents to appear on the outer surface of the shaft cover 20.

[0093] In other embodiments, reference is made to Figure 7 and Figure 8 , Figure 7 yes Figure 3 The schematic diagram shows the structure in which the bearing base 10 of the rotating mechanism 100 is fixed by the shaft cover 20 and the support plate 30 via the connecting assembly 70. Figure 8This is a schematic diagram of the split structure of the shaft cover 20, support plate 30, and connecting assembly 70 provided in the first specific embodiment of this application. The shaft cover 20 includes a body portion 40 and two first mounting portions 50. The support plate 30 has two second mounting portions 60, which are located at opposite ends of the support plate 30 along the Y-axis. The bearing base 10 also includes a connecting assembly 70. There can be two connecting assemblies 70, one set of first mounting portions 50 and second mounting portions 60 connected by one connecting assembly 70, and the other set of first mounting portions 50 and second mounting portions 60 connected by another connecting assembly 70. Specifically, the connecting assembly 70 includes a connector 71. One end of the connector 71 is fixed to the first mounting portion 50, and the other end of the connector 71 is fixed to the second mounting portion 60, so that the shaft cover 20 and the support plate 30 are fixedly connected. One of the first mounting portions 50 and the second mounting portion 60 has a locking hole 52, and the other has an assembly structure. One end of the connector 71 is fixed in the locking hole 52, and the other end of the connector 71 is fixed to the assembly structure.

[0094] The bottom surface of the main body 40 is the exterior surface, and the top surface of the main body 40 is the mounting surface 41. The mounting surface 41 can be an arc-shaped surface or a flat surface. Two first mounting portions 50 are respectively protruding from opposite ends of the mounting surface 41 of the main body 40 along the Y-axis direction, and the two first mounting portions 50 are spaced apart from each other along the Y-axis direction. The gap between the two first mounting portions 50 is used to mount the support plate 30. Each first mounting portion 50 includes a first end face 51.

[0095] The mounting surface 41 of the main body 40 is also provided with a limiting part 42, and the limiting part 42 is provided with a first limiting surface 43. Along the Y-axis direction, the limiting part 42 and the first mounting part 50 are spaced apart and opposite to each other, the first limiting surface 43 and the first end face 51 are spaced apart and opposite to each other, and a limiting groove 44 is formed between the first limiting surface 43 and the first end face 51. The limiting groove 44 is used to install the support plate 30.

[0096] Two second mounting portions 60 are located at opposite ends of the support plate 30 along the Y-axis direction. Each second mounting portion 60 includes a second end face 61 and a second limiting face 62, which are opposite to each other along the Y-axis direction.

[0097] Along the Z-axis, the support plate 30 is stacked on the body portion 40 of the shaft cover 20, and a receiving groove 11 is formed between the support plate 30 and the body portion 40 of the shaft cover 20. Along the Y-axis, the support plate 30 is located in the interval between the two first mounting portions 50, and the two second mounting portions 60 are respectively installed in the two limiting grooves 44. The two second mounting portions 60 abut against the two first mounting portions 50, specifically, the first end face 51 of the first mounting portion 50 abuts against the second end face 61 of the second mounting portion 60, and the first limiting surface 43 abuts against the second limiting surface 62.

[0098] In this embodiment, the first mounting part 50 and the second mounting part 60 are arranged along the Y-axis and fixedly connected by the connector 71. At this time, the fixing force between the support plate 30 and the shaft cover 20 is parallel to the Y-axis direction. This fixing method mainly occupies space in the Y-axis direction, with less space requirement in the Z-axis direction. Compared with the above embodiment, this method ensures a reliable connection between the support plate 30 and the shaft cover 20 without interfering with the display screen 300, thus preventing damage to the display screen 300. It also avoids dents on the surface of the shaft cover 20, increasing its aesthetic appeal.

[0099] Several specific implementation methods are described in detail below.

[0100] First specific implementation method

[0101] refer to Figure 8 The connecting component 70 includes a connector 71 and a stopper 72. For example, the connector 71 can be rod-shaped, and the stopper 72 can be cuboid-shaped. Of course, the connector 71 and the stopper 72 can also have other structural forms, and this application is not limited thereto. The first end face 51 of the first mounting part 50 is recessed with a locking hole 52, and the second end face 61 of the second mounting part 60 is recessed with a mounting hole 63. The supporting surface of the second mounting part 60 is recessed with a receiving groove 64, which communicates with the mounting hole 63. The receiving groove 64 and the mounting hole 63 together constitute an assembly structure.

[0102] refer to Figure 8 , Figure 9 and Figure 10 , Figure 9 yes Figure 8 The schematic diagram shows the assembly of the shaft cover 20, support plate 30, and connecting assembly 70 of the rotating mechanism 100 shown. Figure 10 yes Figure 9 The diagram shows a sectional view (AA section). The second mounting part 60 is installed within the limiting groove 44. When the first mounting part 50 and the second mounting part 60 abut against each other, along the Y-axis, the locking hole 52 and the mounting hole 63 are opposite and connected. The connecting member 71 passes through the mounting hole 63 and extends into the locking hole 52, so that a portion of the connecting member 71 is fixed to the locking hole 52, and the other portion is fixed to the mounting hole 63. A stop member 72 is disposed within the receiving groove 64, and the stop member 72 abuts against the end of the connecting member 71 and the side surface of the receiving groove 64. The stop member 72 is fixedly connected to the second mounting part 60, and the stop member 72 can be welded to the side surface of the receiving groove 64. The stop member 72 applies a force to the connecting member 71, allowing the connecting member 71 to better fix the support plate 30 and the shaft cover 20, increasing the reliability of the fixation of the support plate 30 and the shaft cover 20.

[0103] Specifically, when assembling the shaft cover 20 and the support plate 30, the connecting piece 71 enters the mounting hole 63 from the storage groove 64, then enters the locking hole 52 from the mounting hole 63, and then the abutment piece 72 is placed in the storage groove 64.

[0104] In this embodiment, there are two connectors 71 and two abutments 72. Accordingly, two locking holes 52, two mounting holes 63, and two storage slots 64 are required. Of course, it is also possible to provide only one connector 71 and one abutment 72. Alternatively, three connectors 71 and three abutments 72 can be provided, etc.

[0105] In some embodiments, reference is made to Figure 11 , Figure 11 yes Figure 9 The figure shows a BB sectional view. The connector 71 has an inclined surface 73, which slopes downwards from the front upper part to the rear lower part. The inclined surface 73 of the connector 71 abuts against the top wall of the locking hole 52. From the opening of the locking hole 52 to the bottom surface, the interference between the inclined surface 73 and the top wall of the locking hole 52 gradually increases, which can increase the reliability of the fixing of the connector 71 and the shaft cover 20. Furthermore, the inclined surface 73 also causes the outer diameter of the connector 71 to gradually increase. When assembling the shaft cover 20 and the support plate 30, the end of the connector 71 with the smaller outer diameter extends into the locking hole 52 first, facilitating the insertion of the connector 71 into the locking hole 52.

[0106] Alternatively, the top wall of the locking hole 52 can be an inclined surface 73. The top of the connector 71 abuts against the inclined surface 73, and the amount of interference between the inclined surface 73 and the top of the connector 71 gradually increases from the opening of the locking hole 52 to the bottom surface, which can increase the reliability of the connection between the connector 71 and the shaft cover 20.

[0107] In some embodiments, the abutment 72 may not be provided. Instead, after the connector 71 passes through the locking hole 52 and the mounting hole 63, an auxiliary tool is used to reliably fix the connector 71 in the locking hole 52 and the mounting hole 63, and then the connector 71 is welded to the second mounting part 60.

[0108] In some embodiments, the locking hole 52 may be located in the second mounting portion 60, and the mounting hole 63 and the receiving groove 64 may be located in the first mounting portion 50. In this case, the process of fixing the connecting assembly 70 to the connecting shaft cover 20 and the support plate 30 is similar to that described above, and will not be repeated here.

[0109] Second specific implementation method

[0110] refer to Figure 12 , Figure 12This is a schematic diagram of the split structure of the shaft cover 20, support plate 30, and connecting assembly 70 provided in the second specific embodiment of this application. The connecting assembly 70 includes a connector 71 and abutment 72. There are two connectors 71, namely a first connector 80 and a second connector 90. The first connector 80 includes a first connecting segment 81 and a second connecting segment 82 fixedly connected at an included angle, and the second connector 90 includes a third connecting segment 91 and a fourth connecting segment 92 fixedly connected at an included angle. The included angle between the first connecting segment 81 and the second connecting segment 82 can be 90 degrees, that is, the first connecting segment 81 and the second connecting segment 82 can be connected in an L-shape. Similarly, the included angle between the third connecting segment 91 and the fourth connecting segment 92 can also be 90 degrees, that is, the third connecting segment 91 and the fourth connecting segment 92 can be connected in an L-shape.

[0111] A locking hole 52 is recessed on the first end face 51 of the first mounting part 50, and a mounting hole 63 is recessed on the second end face 61 of the second mounting part 60. The mounting hole 63 also penetrates the support surface of the second mounting part 60. The mounting hole 63 is the assembly structure. The mounting hole 63 includes a first side surface 65 and a second side surface 66 opposite to each other along the X-axis direction. A first mounting groove 67 is recessed on the first side surface 65, and a first mounting groove 67 is recessed on the second side surface 66.

[0112] refer to Figure 13 and Figure 14 , Figure 13 yes Figure 12 The schematic diagram shows the assembly of the shaft cover 20, support plate 30, and connecting assembly 70 of the rotating mechanism 100 shown. Figure 14 yes Figure 13 The image shows a CC sectional view. The second mounting part 60 is installed within the limiting groove 44. When the first mounting part 50 and the second mounting part 60 abut against each other, the locking hole 52 and the mounting hole 63 are opposite and connected along the Y-axis. The first connecting member 80 and the second connecting member 90 are both disposed within the mounting hole 63. The first connecting section 81 of the first connecting member 80 extends into the first mounting groove 67, and the second connecting section 82 of the first connecting member 80 extends into the locking hole 52. The third connecting section 91 of the second connecting member 90 extends into the first mounting groove 67, and the fourth connecting section 92 of the second connecting member 90 extends into the locking hole 52. A stop member 72 is disposed within the mounting hole 63, and the two opposite sides of the stop member 72 abut against the second connecting section 82 of the first connecting member 80 and the fourth connecting section 92 of the second connecting member 90, respectively. The stop member 72 can be welded and fixed within the mounting hole 63. Thus, a supporting member 72 can apply a force to the two connecting members 71, so that the connecting members 71 reliably fix the support plate 30 and the shaft cover 20 together.

[0113] Both the first connecting member 80 and the second connecting member 90 are L-shaped, so that when the abutment member 72 pushes the first connecting member 80 and the second connecting member 90 away from each other along the X-axis, the first connecting segment 81 and the third connecting segment 91 can be more firmly connected to the second mounting part 60, and the second connecting segment 82 and the fourth connecting segment 92 can be more firmly connected to the first mounting part 50. The assembly process is simple and can increase the reliability of the connection between the shaft cover 20 and the support plate 30.

[0114] In some embodiments, reference is made to Figure 15 , Figure 15 yes Figure 13 The DD cross-sectional view shows that the top wall surface of the first connecting segment 81 of the first connector 80 can be a first inclined surface 83, and the top wall surface of the third connecting segment 91 of the second connector 90 can be a second inclined surface 93. Both the first inclined surface 83 and the second inclined surface 93 are inclined relative to the plane formed along the X-axis and Y-axis directions, and the inclination directions of the first inclined surface 83 and the second inclined surface 93 are opposite. Specifically, when taking the positive X-axis direction as right, the negative X-axis direction as left, the positive Z-axis direction as up, and the negative Z-axis direction as down as a reference, the first inclined surface 83 is located on the left, and the second inclined surface 93 is located on the right. The first inclined surface 83 inclines from the upper right to the lower left, and the second inclined surface 93 inclines from the upper left to the lower right. When the abutment 72 is installed between the first connector 80 and the second connector 90, the abutment 72 pushes the first connector 80 and the second connector 90 away from each other in the X-axis direction. At this time, the interference between the first inclined surface 83 and the top wall of the first mounting groove 67 gradually increases, and the interference between the second inclined surface 93 and the top wall of the first mounting groove 67 gradually increases, making the connection between the first connector 80 and the second connector 90 and the shaft cover 20 more reliable.

[0115] Alternatively, the top wall surface of the first mounting groove 67 includes a first inclined surface 83, and the top wall surface of the first mounting groove 67 includes a second inclined surface 93. When the abutment 72 pushes the first connector 80 and the second connector 90 away from each other in the X-axis direction, the interference between the first inclined surface 83 and the top wall surface of the first connecting segment 81 gradually increases, and the interference between the second inclined surface 93 and the top wall surface of the third connecting segment 91 gradually increases, making the connection between the first connector 80 and the second connector 90 and the shaft cover 20 more reliable.

[0116] In some embodiments, reference is made to Figure 16 , Figure 16 yes Figure 13The EE sectional view shows that the top wall surface of the second connecting segment 82 of the first connector 80 can be a third inclined surface 84, and the top wall surface of the fourth connecting segment 92 of the second connector 90 can be a fourth inclined surface 94. Both the third inclined surface 84 and the fourth inclined surface 94 are inclined relative to the plane formed along the X-axis and Y-axis directions, and their inclination directions are opposite. Specifically, the third inclined surface 84 is located on the left, and the fourth inclined surface 94 is located on the right. The third inclined surface 84 inclines from the upper right to the lower left, and the fourth inclined surface 94 inclines from the upper left to the lower right. When the abutment 72 is installed between the first connector 80 and the second connector 90, the abutment 72 pushes the first connector 80 and the second connector 90 away from each other in the X-axis direction. At this time, the interference between the third inclined surface 84 and the top wall surface of the locking hole 52 gradually increases, and the interference between the fourth inclined surface 94 and the top wall surface of the locking hole 52 gradually increases, making the connection between the first connector 80 and the second connector 90 and the shaft cover 20 more reliable.

[0117] Alternatively, the top wall surface of the locking hole 52 includes a third inclined surface 84 and a fourth inclined surface 94. When the abutment 72 pushes the first connector 80 and the second connector 90 away from each other in the X-axis direction, the interference between the top wall surfaces of the third inclined surface 84 and the second connecting segment 82 gradually increases, and the interference between the top wall surfaces of the fourth inclined surface 94 and the fourth connecting segment 92 gradually increases, making the connection between the first connector 80 and the second connector 90 and the shaft cover 20 more reliable.

[0118] In some embodiments, the locking hole 52 may be provided in the second mounting portion 60, and the mounting hole 63, the first mounting groove 67, and the first mounting groove 67 may be provided in the first mounting portion 50. In this case, the process of fixing the connecting assembly 70 to the connecting shaft cover 20 and the support plate 30 is similar to that described above, and will not be repeated here.

[0119] Third specific implementation method

[0120] refer to Figure 17 , Figure 17 This is a schematic diagram of the split structure of the shaft cover 20, support plate 30, and connecting assembly 70 provided in the third specific embodiment of this application. The connecting assembly 70 only includes a connector 71. The first end face 51 of the first mounting part 50 is provided with a locking hole 52. The connector 71 is fixed to the second end face 61 of the second mounting part 60. The connector 71 can be integrally formed on the second mounting part 60, or it can be fixed to the second mounting part 60 by welding or fastener connection. The second end face 61 is the assembly structure.

[0121] refer to Figure 18 and Figure 19 , Figure 18 yes Figure 17The schematic diagram shows the assembly of the shaft cover 20, support plate 30, and connecting assembly 70 of the rotating mechanism 100 shown. Figure 19 yes Figure 18 The FF sectional view. When assembling the shaft cover 20 and the support plate 30, an external force can be used to deform the support plate 30 along the Y-axis direction, so that the second mounting part 60 is installed in the limiting groove 44, thereby allowing the connecting piece 71 to extend into the locking hole 52. Then, the external force is removed, the first mounting part 50 and the second mounting part 60 abut against each other, and the shaft cover 20 and the support plate 30 are fixedly connected by the connecting piece 71.

[0122] It is understood that the dimension of the connector 71 along the Y-axis is approximately 0.5 mm, and the dimension of the support plate 30 along the Y-axis is approximately 150 mm. Therefore, a very small deformation of the support plate 30 is sufficient for the connector 71 to extend into the locking hole 52. Specifically, when assembling the shaft cover 20 and the support plate 30, the deformation rate of the support plate 30 along the Y-axis (X2-X1) / X2 is less than 0.5%, which will not affect the structural strength of the support plate 30. Here, X1 is the length of the support plate 30 along the Y-axis after deformation, and X2 is the length of the support plate 30 along the Y-axis after deformation.

[0123] In some embodiments, reference is made to Figure 20 , Figure 20 yes Figure 18 The figure shows a cross-sectional view of the connector 71. The connector 71 has an inclined surface 73, which slopes from the upper front to the lower rear. The inclined surface 73 of the connector 71 abuts against the top wall of the locking hole 52. From the opening of the locking hole 52 to the bottom surface, the amount of interference between the inclined surface 73 and the top wall of the locking hole 52 gradually increases, which can increase the reliability of the connection between the connector 71 and the shaft cover 20.

[0124] Alternatively, the top wall of the locking hole 52 can be an inclined surface 73. The top of the connector 71 abuts against the inclined surface 73, and the amount of interference between the inclined surface 73 and the top of the connector 71 gradually increases from the opening of the locking hole 52 to the bottom surface, which can increase the reliability of the connection between the connector 71 and the shaft cover 20.

[0125] In some embodiments, the connector 71 can be fixed to the first end face 51 of the first mounting portion 50, while a locking hole 52 is provided on the second end face 61 of the second mounting portion 60. In this case, the process of fixing the connecting shaft cover 20 and the support plate 30 with the connecting assembly 70 is similar to that described above, and will not be repeated here.

[0126] Fourth specific implementation method

[0127] refer to Figure 21 and Figure 22 , Figure 21 This is a schematic diagram of the split structure of the shaft cover 20, support plate 30, and connecting assembly 70 provided in the fourth specific embodiment of this application. Figure 22 This is a schematic diagram of the first structure of the connecting component 70 in the fourth embodiment of this application. The connecting component 70 includes only a connector 71, which includes an operating part 74 and two fixing parts 75. The two fixing parts 75 are respectively fixed to both sides of the operating part 74 along the X-axis direction, and the two fixing parts 75 are symmetrical about the central axis of the operating part 74 along the Y-axis direction. Each fixing part 75 includes a first connecting body 76, a second connecting body 77, and a flexible body 78. The first connecting body 76 is fixed to one side of the flexible body 78 along the Y-axis direction, the second connecting body 77 is fixed to one side of the flexible body 78 along the X-axis direction, and the other side of the flexible body 78 along the X-axis direction is fixed to the operating part 74. The operating part 74 is provided with an operating slope 79. Specifically, when taking the positive Y-axis direction as front, the negative Y-axis direction as rear, the positive Z-axis direction as up, and the negative Z-axis direction as down as reference, the operating slope 79 is inclined from the lower front to the upper rear. The flexible body 78, the first connector 76, the second connector 77, and the operating part 74 are all made of the same material, such as metal. The flexible body 78 can be configured as a sheet to give it elastic deformation capability. Of course, the flexible body 78 can also be made of other materials, as long as it ensures that it has elastic deformation capability.

[0128] The flexible body 78 includes at least one of a straight beam, an inclined beam, and a curved beam. For example, see reference... Figure 22 and Figure 23 , Figure 23 This is a schematic diagram of the second structure of the connecting component in the fourth specific embodiment of this application. Figure 22 and Figure 23 The flexible body 78 shown consists only of straight beams, and Figure 22 The flexible body 78 shown is L-shaped. Figure 23 The flexible body 78 shown is in the shape of an "I". (Reference) Figure 24 , Figure 24 This is a schematic diagram of the second structure of the connecting component 70 in the fourth embodiment of this application. Figure 24 The flexible body 78 shown only includes the inclined beam. (Reference) Figure 25 , Figure 25 This is a schematic diagram of the third structure of the connecting component 70 in the fourth specific embodiment of this application. Figure 25 The flexible body 78 shown only includes curved beams. (Reference) Figure 26 , Figure 26 This is a schematic diagram of the fourth structure of the connecting component 70 in the fourth specific embodiment of this application. Figure 26 The flexible body 78 shown includes multiple straight beams arranged in parallel. (Reference) Figure 27 , Figure 27 This is a schematic diagram of the fifth structure of the connecting component 70 in the fourth specific embodiment of this application. Figure 27The flexible body 78 shown includes multiple straight beams arranged in series.

[0129] refer to Figure 21 The first mounting portion 50 is provided with two locking holes 52, both of which are recessed into the first end face 51 of the first mounting portion 50. The two locking holes 52 can be two independent holes that are not connected to each other. (Reference) Figure 28 , Figure 28 yes Figure 21 The diagram shows a structural schematic of the support plate 30 from another perspective. The second mounting part 60 is provided with an operating hole 69 and two mounting holes 63. The operating hole 69 penetrates the second mounting part 60 along the Z-axis direction, and the mounting holes 63 are recessed on the surface of the second mounting part 60 facing the shaft cover 20 and penetrate the side of the second mounting part 60. The mounting holes 63 constitute the assembly structure.

[0130] refer to Figure 29 , Figure 29 yes Figure 21 The diagram shows the structural arrangement of the support plate 30 and connecting assembly 70. When assembling the shaft cover 20 and support plate 30, the connecting piece 71 is fixed to the second mounting portion 60. Specifically, the second connecting bodies 77 of the two fixing portions 75 are respectively fixed within the two mounting holes 63. The second connecting bodies 77 can be fixed to the mounting holes 63 by welding, with a portion of the second connecting body 77 located outside the mounting holes 63. At this time, the operating portion 74 and the operating hole 69 are opposite each other, with the operating inclined surface 79 facing the operating hole 69. The first connecting body 76, the flexible body 78, and a portion of the second connecting body 77 are all stacked on the bottom of the second connecting body 77. The first connecting bodies 76 of the two fixing portions 75 protrude relative to the second end face 61 of the second mounting portion 60.

[0131] refer to Figure 30 , Figure 31 and Figure 32 , Figure 30 yes Figure 21 The diagram shows the assembly of the shaft cover 20, support plate 30, and connecting assembly 70. Figure 31 yes Figure 30 HH sectional view, Figure 32 yes Figure 30The LL sectional view is shown. Next, an auxiliary tool 400 with an auxiliary inclined surface 410 is inserted into the operating hole 69, so that the auxiliary inclined surface 410 of the auxiliary tool 400 contacts the operating inclined surface 79. Then, the operating part 74 is moved in the positive Y-axis direction by the auxiliary tool 400. The operating part 74 causes the flexible body 78 to deform in the positive Y-axis direction. The flexible body 78 causes the first connecting body 76 of the two fixing parts 75 to move in the positive Y-axis direction, so that the first connecting body 76 moves to at least a position flush with the second end face 61. Then, the support plate 30 is placed in the gap between the two first mounting parts 50, so that the second mounting part 60 is installed in the limiting groove 44. At this time, the connecting member 71 is located between the support plate 30 and the shaft cover 20. Next, the auxiliary tool 400 is removed from the operating hole 69. At this time, the flexible body 78 is reset, causing the first connecting body 76 to move in the negative Y-axis direction. The first connecting body 76 extends into the locking hole 52, so that the support plate 30 and the shaft cover 20 are fixedly connected.

[0132] In some embodiments, reference is made to Figure 33 , Figure 33 yes Figure 21 The diagram shows the state changes of the connecting assembly 70 during the assembly process of the shaft cover 20, support plate 30, and connecting assembly 70. From... Figure 33 As can be seen, when the flexible body 78 deforms, the two first connecting bodies 76 move in the positive Y-axis direction while simultaneously moving closer to each other along the X-axis direction. (Reference) Figure 34 , Figure 34 This is another structural schematic diagram of the shaft cover 20 in the fourth specific embodiment of this application. Along the X-axis, the two locking holes 52 are connected. Providing the two locking holes 52 to be connected along the X-axis increases the space between them. This facilitates the insertion and removal of the first connecting body 76 from the locking holes 52, making it easier to assemble and disassemble the support plate 30 and the shaft cover 20.

[0133] In some embodiments, two locking holes 52 can be provided in the second mounting portion 60, and the operating hole 69 and two mounting holes 63 can be provided in the first mounting portion 50. It is understood that, in this case, the first mounting portion 50 can be detached from the shaft cover 20. After the connecting piece 71 is fixed in the two locking holes 52 and the operating ramp 79 is aligned with the operating hole 69, the first mounting portion 50 is then fixedly mounted onto the shaft cover 20. The subsequent assembly process of the shaft cover 20 and the support plate 30 is as described above and will not be repeated here.

[0134] In some embodiments, reference is made to Figure 35 , Figure 35 yes Figure 3The diagram shows a partial structural schematic of the rotating mechanism 100. The fixing assembly 110 includes a first fixing member 111 and a second fixing member 112, both of which can be wedge-shaped blocks.

[0139] When the foldable electronic device 1000 switches from an unfolded state to a folded state, or vice versa, the first housing 210 and the second housing 220 rotate around the support base 10. At this time, the first main swing arm 121 slides and rotates relative to the support base 10 and rotates relative to the first fixing member 111. The second main swing arm 122 slides and rotates relative to the support base 10 and rotates relative to the second fixing member 112.

The second swing arm 132 rotates relative to the support base 10 and slides and rotates relative to the second fixing member 112. During the movement of the first swing arm 131 and the second swing arm 132, the first drive gear, the two synchronous gears 133, and the second drive gear rotate synchronously, causing the first swing arm 131 and the second swing arm 132 to move synchronously, thereby achieving synchronous movement of the first housing 210 and the second housing 220. Furthermore, during the movement of the first swing arm 131 and the second swing arm 132, the engagement of the first and third protrusions 146 and the second and fourth protrusions 137 changes, causing the first elastic element 142, the second elastic element 143, and the auxiliary elastic element 144 to be compressed or extended, thereby providing damping force for the first housing 210 and the second housing 220. The change in the engagement of the first and third protrusions 146 means that, as the first and second swing arms 131 and 132 rotate, the first and third protrusions 146 can switch between peak-valley engagement and peak-peak engagement. Peak-valley engagement means that the protrusion of the first protrusion 146 is located within the recess of the third protrusion 136, and vice versa. Peak-to-peak mating refers to the contact between the convex portion of the first concave-convex portion 146 and the convex portion of the third concave-convex portion 136.
