Description

Technical Field

[0001] This disclosure relates to the field of hinge structure design for foldable screen electronic devices, and more particularly to a hinge structure, a display module, and an electronic device. Background Technology

[0002] With the rapid development of technology, foldable electronic devices will become a future trend. For foldable electronic devices, the hinge structure is crucial, directly affecting their functionality and user experience. Typically, the torque component in a hinge structure provides torque, allowing the electronic device to be better fixed at the desired angle. However, in existing hinge structures, the torque component is usually located in the middle of the hinge, resulting in limited torque provided. Summary of the Invention

[0003] To overcome the problems existing in the related technologies, this disclosure provides a hinge structure, a display module, and an electronic device that can increase the torque provided by the torque component.

[0004] According to a first aspect of the present disclosure, a hinge structure is provided, comprising:

[0005] Base frame;

[0006] A torque assembly, disposed on the base frame, includes a first cam assembly and a second cam assembly;

[0010] In some embodiments, both the first cam assembly and the second cam assembly include: a cam pin disposed along the second direction;

[0011] The torque component further includes:

[0012] A pin connector is used to connect the cam pin of the first cam assembly and the cam pin of the second cam assembly.

[0029] The cam pin of the second cam assembly passes through the cam rod of the second cam assembly, the cam plate of the second cam assembly, the elastic element, and the baffle.

[0030] When the rotating assembly rotates, the cam plate of the second cam assembly and the baffle apply forces in opposite directions to the elastic element, causing the elastic element to be compressed.

[0031] In some embodiments, the base frame is provided with the torque component and the rotation component at both the first end and the second end along the first direction; the rotation component at the same end is disposed between the first cam component and the second cam component of the torque component at the same end;

[0036] The second synchronizing element is connected to the cam rod of the second cam assembly at the second end;

[0039] The base frame is provided with the fixing block at both the first end and the second end along the first direction;

[0040] The fixed block is connected to the cam rod of the first cam assembly, the cam rod of the second cam assembly, and the rotating assembly, which are located at the same end.

[0042] A cover plate, fixed to the base frame, is capable of covering the torque assembly and part of the rotation assembly;

[0043] The cover plate can serve as a screen support structure.

[0045] Screen;

[0046] The hinge structure as described in the first aspect above;

[0047] The hinge structure connects to the screen and can drive the screen to fold.

[0054] In this embodiment, the first cam assembly and the second cam assembly are respectively disposed at the two ends of the base frame along the second direction, and the rotating assembly is disposed between the first cam assembly and the second cam assembly. Thus, by providing two cam assemblies at the ends of the base frame, this embodiment not only increases the torque of the hinge structure but also makes more rational use of the space of the hinge in the second direction, improving the space utilization rate of the hinge structure.

[0068] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0069] This disclosure provides a hinge structure. For example... Figures 1 to 6 As shown, the hinge structure of this embodiment includes:

[0070] Base frame 1;

[0071] Torque assembly 2 is disposed on the base frame 1 and includes a first cam assembly 21 and a second cam assembly 22;

[0072] Rotating component 3 is rotatably connected to the end of the base frame 1 along the first direction A, and is disposed between the first cam component 21 and the second cam component 22;

[0073] The first cam assembly 21 and the second cam assembly 22 are disposed at two ends of the base frame 1 along the second direction B, and are both used to provide torque when the rotating assembly 3 rotates;

[0074] Wherein, the first direction A intersects with the second direction B.

[0075] In this embodiment, the hinge structure is used to realize the folding of the electronic device, and also has the function of supporting the screen or mid-frame. For example, in a video viewing scenario, the hinge structure allows the screen of the foldable electronic device to unfold, allowing the user to view a larger screen. As another example, in a carrying scenario, the hinge structure allows the screen of the foldable electronic device to fold, so that the foldable electronic device can be carried in a smaller space.

[0076] It should be noted that the hinge structure described above has an unfolded state and a folded state. When the hinge structure is in the unfolded state, the screen of the foldable electronic device is unfolded, which can improve the user's screen viewing experience; when the hinge structure is in the folded state, the foldable electronic device occupies the least space and is easy to carry.

[0077] The aforementioned base frame can be a load-bearing base frame for a hinge structure, used to support various components in the hinge structure, such as torsion components and rotation components, etc. The embodiments disclosed herein do not impose any limitations on this.

[0078] The aforementioned torque assembly, mounted on the base frame, provides torque, enabling the hinge structure to be better fixed at the desired angle. For example, the torque assembly allows the hinge structure to be better positioned in an unfolded or folded state.

[0079] The aforementioned rotating component is a key part of the hinge structure that enables it to switch between an unfolded state and a folded state, allowing the hinge structure to switch from a folded state to an unfolded state, or vice versa.

[0080] It should be noted that the rotating assembly may consist of a track rod and / or at least one track link.

[0081] For example, the rotating component includes a track rod; the track rod is rotatably connected to the base frame and fixedly connected to the fixing block in the hinge structure for fixing the first and second middle frames of the electronic device, so that when an external force is applied to the first and / or second middle frames, the track rod can rotate relative to the base frame to realize the switching of the hinge structure between the folded state and the unfolded state.

[0082] For example, the rotating component includes a track rod and two track links; the track rod is rotatably connected to the two track links and the base frame, and the track rod is connected to the fixing block through the two track links. Thus, when an external force is applied to the first middle frame and / or the second middle frame, the track rod can rotate relative to the base frame through the action of the fixing block and the two track links, so as to realize the switching of the hinge structure between the folded state and the unfolded state.

[0083] The aforementioned rotating assembly is rotatably connected to the end of the base frame along the first direction. Here, the end of the base frame along the first direction may include a first end and a second end, and rotating assemblies may be respectively provided at the first end and the second end, so that the hinge structure can be better switched between the folded state and the unfolded state through the rotating assemblies at the two ends.

[0084] It should be noted that, as Figure 1 As shown, the first direction A may include the width direction of the base frame 1. The rotating component 3 can rotate relative to the base frame 1 about a direction perpendicular to the first direction, that is, the extension direction of the rotation axis of the rotating component 3 is perpendicular to the first direction A.

[0085] For example, the rotating component can rotate about the vertical direction of the first direction relative to the direction closer to the base frame, and it can also rotate about the vertical direction of the first direction relative to the direction farther away from the base frame.

[0086] The aforementioned torque assembly includes a first cam assembly and a second cam assembly, which are disposed at two ends of the base frame along a second direction. That is, in this embodiment, the two cam assemblies are not located in the middle of the hinge structure, but rather at the ends of the base frame, which increases the torque during hinge structure rotation. Furthermore, this embodiment enables the two cam assemblies at the ends to better support the housing of the electronic device when the hinge structure is applied to an electronic device.

[0087] It should be noted that, as Figure 1 As shown, the second direction B may include the length direction of the base frame 1 or the extension direction of the rotation axis of the rotating component 3. That is, the rotating component 3, the first cam component 21 and the second cam component 22 of this embodiment can be arranged along the length direction of the base frame 1, thereby making better use of the space of the base frame in the length direction.

[0088] In this embodiment of the disclosure, the first direction intersects the second direction, and the angle between the first direction and the second direction can be between 80 degrees and 100 degrees. For example, the first direction can be perpendicular to the second direction.

[0089] The first cam assembly and the second cam assembly described above provide torque when the rotating assembly rotates, which may include providing torque by utilizing the friction between at least two cam elements in the two cam assemblies.

[0090] For example, both cam assemblies include three cam elements that are pressed against each other, which can generate friction between adjacent cam elements in the same cam assembly when the rotating assembly rotates, thereby providing torque.

[0091] It should be noted that the first cam assembly and the second cam assembly can provide torque when the rotating assembly rotates by sharing a single pin, or by setting multiple pins to provide torque when the rotating assembly rotates. This disclosure does not limit this.

[0092] In this embodiment, the first cam assembly and the second cam assembly are respectively disposed at the two ends of the base frame along the second direction, and the rotating assembly is disposed between the first cam assembly and the second cam assembly. Thus, by providing two cam assemblies at the ends of the base frame, this embodiment not only increases the torque of the hinge structure but also makes more efficient use of the space of the hinge in the second direction, improving the space utilization rate of the hinge structure.

[0093] In some embodiments, such as Figures 1 to 5 As shown, both the first cam assembly 21 and the second cam assembly 22 include a cam pin 23 disposed along the second direction B;

[0094] The torque assembly 2 further includes:

[0095] The pin connector 24 is connected between the cam pin 23 of the first cam assembly 21 and the cam pin 23 of the second cam assembly 22;

[0096] The rotating component 3 is offset from the pin connector 24 on the third direction C;

[0097] Wherein, the third direction C is perpendicular to the plane.

[0098] In this embodiment, the pin connector is connected to the cam pin of the first cam assembly and the cam pin of the second cam assembly. In other words, this embodiment uses three pins to provide torque to the torque assembly.

[0099] It should be noted that the pin connector can be fixedly connected to the cam pin of the first cam assembly and the cam pin of the second cam assembly, which facilitates the torque assembly to provide greater torque.

[0100] Here, during the torque delivery process of the torque assembly, the pin connector can move along the second direction but cannot rotate around the second direction. This can be achieved by providing a groove on the base frame, allowing the pin connector to slide along the second direction within the groove through its engagement with the groove.

[0101] For example, the pin connector may include a pin connecting rod or a pin connecting block, and this disclosure does not limit the embodiments. The length of the pin connector in the second direction is positively correlated with the distance between the cam pins of the first cam assembly and the cam pins of the second cam assembly. That is, the greater the distance, the longer the length of the pin connector in the second direction.

[0102] In this embodiment, the rotating assembly is offset from the pin connector in the third direction. That is, the rotating assembly and the pin connector are not located on the plane containing the first and second directions, but rather at different heights in the third direction of the base frame; that is, the rotating assembly and the pin connector are spaced apart in the third direction. This makes the layout of the rotating assembly and the two cam assemblies in the second direction more rational.

[0103] It should be noted that the third direction may include the height direction of the base frame. This third direction may be perpendicular to both the first direction and the second direction.

[0104] In this embodiment, since the rotating component directly controls the rotation trajectory of the hinge structure switching between the unfolded and folded states, it is difficult to avoid the rotating component sharing the center of a single cam pin between the two cam components. Therefore, this embodiment proposes to provide a pin connector and two cam pins for the two cam components, connecting the cam pins of the first and second cam components via the pin connector, and setting the rotating component and the pin connector to be offset in a third direction.

[0105] In other words, the pin connector of the torque component in this embodiment of the present disclosure, by crossing the rotation component, can increase the torque of the hinge structure under rotation while achieving better folding, so that the hinge structure can be more stably fixed at the required angle.

[0106] In some embodiments, such as Figure 2 As shown, the pin connector 24 is recessed towards the base frame 1 to form a clearance space (not shown in the figure);

[0107] The rotating component 3 is at least partially located within the clearance space.

[0108] In this embodiment of the present disclosure, the projection of the pin connector onto the rotating assembly is located on the rotating assembly.

[0109] It should be noted that the pin connector can be recessed towards the base frame to form a groove, and the accommodating space of the groove constitutes the clearance space; or, the length of the pin connector in the third direction can be shortened from a first length to a second length, and the space occupied by the shortened part constitutes the clearance space.

[0110] The aforementioned rotating assembly may include a first portion connecting the base frame and a second portion offset from the pin connector in a third direction. The second portion may be partially or entirely located within the clearance space.

[0111] It is understandable that placing the rotating component at least partially within the clearance space can shorten the length of the hinge structure in the third direction and reduce the space occupied by the hinge structure.

[0112] In some embodiments, such as Figure 2 and Figure 5 As shown, the pin connector 24 has a first surface D facing the rotating assembly 3, and the rotating assembly 3 has a second surface E facing the pin connector 24.

[0113] The first surface D and the second surface E are parallel planes; or, the first surface C and the second surface E are arc surfaces with the same curvature.

[0114] In this embodiment of the present disclosure, the orthographic projection of the first surface of the pin connector onto the rotating assembly can coincide with the second surface.

[0115] It should be noted that when the first surface is a plane, the first surface and the second surface can be set to be mutually parallel planes.

[0116] For example, such as Figure 5 As shown, the first surface D can be set as a plane inclined towards the center point of the base frame, and the corresponding second surface can also be set as a plane inclined towards the center point of the base frame, and the first surface and the second surface are parallel to each other.

[0117] Of course, when the first surface is curved, both the first and second surfaces can be set to have the same curvature. For example, both the first and second surfaces can be set to be circular arc surfaces.

[0118] It is understandable that setting the first and second surfaces to be parallel planes, or to be curved surfaces with the same curvature, can minimize the length of the hinge structure in the third direction and reduce the space occupied by the hinge structure.

[0119] In some embodiments, such as Figure 1 , Figures 3 to 5 As shown, the torque assembly 2 further includes:

[0120] An elastic element 25 is disposed at one end of the second cam assembly 22 away from the first cam assembly 21 and connected to the cam pin 23 of the second cam assembly 22;

[0121] When the rotating component 3 rotates, the elastic element 25 is compressed, and the compressed elastic element 25 acts on the first cam assembly 21 and the second cam assembly 22, so that the first cam assembly 21 and the second cam assembly 22 provide the torque.

[0122] In this embodiment of the disclosure, such as Figures 3 to 5 As shown, the elastic element 25 and the second cam assembly 22 are disposed at the same end of the base frame 1. For example, when the base frame has a third end and a fourth end along the second direction, the first cam assembly can be disposed at the third end, and the second cam assembly and the elastic element can be disposed at the fourth end.

[0123] Here, the elastic element connected to the second cam assembly may include: the cam pin of the second cam assembly passing through the elastic element; or, the cam pin of the second cam assembly abutting against the elastic element.

[0124] It should be noted that the elastic element includes, but is not limited to, a spring or a spring block. In this embodiment, the degree of compression of the elastic element is positively correlated with the torque provided by the first cam assembly and the second cam assembly. The greater the degree of compression of the elastic element, the greater the torque provided.

[0125] Understandably, the elastic element is connected to the cam pin of the second cam assembly. The pin connector connects the cam pin of the second cam assembly and the cam pin of the first cam assembly. Therefore, when the elastic element is compressed, based on the cam pin of the second cam assembly, the pin connector, and the cam pin of the second cam assembly, the compressed elastic element acts on both the first and second cam assemblies, thereby enabling both cam assemblies to generate torque. In this way, the hinge structure can provide greater torque, allowing the hinge structure to be more stably fixed at the desired angle.

[0126] In some embodiments, such as Figure 1 , Figures 3 to 5 As shown, both the first cam assembly 21 and the second cam assembly 22 include: a cam rod 26 and a cam plate 27 connected to the cam pin 23;

[0127] The cam plate 27 of the second cam assembly 22 is connected between the elastic member 25 and the cam rod 26 of the second cam assembly 22;

[0128] When the compressed elastic element 25 acts on the first cam assembly 21 and the second cam assembly 22, the cam rod 26 and the cam plate 27 in the same cam assembly can generate friction.

[0129] In this embodiment of the present disclosure, both the first cam assembly and the second cam assembly include a cam rod and a cam plate connected to the cam pin. Here, the cam rod and cam plate of the same cam assembly are configured for clamping.

[0130] It should be noted that, as Figure 4 and Figure 5 As shown, in the first cam assembly 21, the cam plate 27 is disposed away from the pin connector 24 relative to the cam rod 26, and in the second cam assembly 22, the cam plate 27 is disposed away from the pin connector 24 relative to the cam rod 26. The pin connector 24 can be disposed between the cam rod 26 of the first cam assembly 21 and the cam rod 26 of the second cam assembly 22.

[0131] In this embodiment of the disclosure, the compressed elastic element acts on the first cam assembly and the second cam assembly, which may include: the compressed elastic element squeezing the cam plate and cam rod in the first cam assembly and squeezing the cam plate and cam rod in the second cam assembly, thereby causing friction between the cam plate and cam rod in the same cam assembly.

[0132] It should be noted that the degree of compression of the elastic element is positively correlated with the frictional force generated by the cam rod and cam plate in the same cam assembly. The greater the degree of compression of the elastic element, the greater the frictional force generated by the cam rod and cam plate in the same cam assembly, and consequently the greater the torque provided by the hinge structure.

[0133] Understandably, during the rotation of the rotating assembly, the elastic element is compressed, which in turn generates friction between the cam rod and the cam plate in the same cam assembly. Thus, the friction generated by the first and second cam assemblies respectively increases the torque provided by the torque assembly, allowing the hinge structure to be more stably fixed at the desired angle.

[0134] In some embodiments, such as Figures 1 to 5 As shown, the cam rod 26 has a first cam surface (not shown in the figure); the cam plate 27 has a second cam surface (not shown in the figure);

[0135] The first cam surface and the second cam surface in the same cam assembly mesh with each other.

[0136] In this embodiment, one of the first cam surface and the second cam surface has a protrusion, and the other cam surface has a groove. The protrusion and the groove are matched to achieve mutual engagement between the first cam surface and the second cam surface.

[0137] For example, the first cam surface may have a first protrusion, and the second cam surface may have a first groove. The first cam surface and the second cam surface can be engaged with each other by the first protrusion fitting into the first groove.

[0138] For example, the first cam surface may have a second groove, and the second cam surface may have a second protrusion. The first cam surface and the second cam surface can be engaged with each other by the second protrusion fitting into the second groove.

[0139] It is understandable that by interlocking the first cam surface and the second cam surface, friction can be generated when the compressed elastic element acts on the first cam assembly and the second cam assembly, thereby increasing the torque provided by the torque assembly.

[0140] In some embodiments, such as Figure 1 and Figure 4 As shown, the hinge structure also includes a baffle 4;

[0141] The elastic element 25 is disposed between the baffle 4 and the cam plate 27 of the second cam assembly 22;

[0142] The cam pin 23 of the second cam assembly 22 passes through the cam rod 26 of the second cam assembly 22, the cam plate 27 of the second cam assembly 22, the elastic element 25 and the baffle 4;

[0143] When the rotating component 3 rotates, the cam plate 27 of the second cam component 22 and the baffle 4 apply opposite forces to the elastic element 25, causing the elastic element 25 to be compressed.

[0144] In this embodiment of the disclosure, such as Figures 3 to 5 As shown, the cam rod 26 of the second cam assembly 22 has a first through hole, the cam plate 27 of the second cam assembly 22 has a second through hole, the baffle 4 has a third through hole, and the elastic element 25 has an elastic ring. The cam pin 23 of the second cam assembly 22 can pass through the first through hole, the second through hole, the elastic ring, and the third through hole in sequence.

[0145] It should be noted that the hinge structure also includes a first pin fixing member, which is fixed to the end of the cam pin of the second cam assembly passing through the third through hole, so as to prevent the baffle from moving away from the elastic member.

[0146] For example, the first pin fixing member can be fixed by threading with the cam pin of the second cam assembly.

[0147] In this embodiment of the disclosure, such as Figures 3 to 5As shown, the cam rod 26 of the first cam assembly 21 has a fourth through hole, the cam plate 27 of the first cam assembly 21 has a fifth through hole, and the cam pin 23 of the first cam assembly 21 passes through the fourth through hole and the fifth through hole.

[0148] It should be noted that the hinge structure also includes a second pin fixing member, which is fixed to the end of the cam pin of the first cam assembly passing through the fifth through hole, so as to prevent the cam plate 27 of the first cam assembly 21 from moving away from the elastic member.

[0149] For example, the second pin fixing member can be fixed by threading with the cam pin of the first cam assembly.

[0150] In this embodiment, the elastic element is disposed between the baffle and the cam plate of the second cam assembly. When the rotating assembly rotates, both the baffle and the cam plate of the second cam assembly apply a force to the elastic element, causing the elastic element to be compressed.

[0151] For example, such as Figure 4 As shown, when the rotating assembly 3 rotates, the cam plate 27 and cam rod 26 of the first cam assembly 21 can generate a displacement X1, which can be converted into compression of the elastic element 25 through the path of the cam pin 23 of the first cam assembly 21, the pin connecting piece 24, the cam pin 23 of the second cam assembly 22, the elastic element 25 and the baffle 4.

[0152] At this time, the direction in which the baffle 4 applies force to the elastic member 25 is parallel to the second direction B and toward the cam plate 27 of the second cam assembly 22. Simultaneously, the cam plate 27 of the second cam assembly 22 and the cam rod 26 of the second cam assembly 22 also generate a displacement X2 to compress the elastic member 25. At this time, the direction in which the cam plate 27 of the second cam assembly 22 applies force to the elastic member 25 is parallel to the second direction B and toward the baffle.

[0153] It should be noted that, since the direction of the force applied by the cam plate 27 of the second cam assembly 22 to the elastic member 25 is opposite to the direction of the force applied by the baffle 4 to the elastic member 25 and acts at both ends of the elastic member 25, the elastic member 25 will have twice the compression. The compressed elastic member 25, through the cam pin 23 and pin connector 24 of the first cam assembly 21, the cam pin 23 of the second cam assembly 22 and the baffle 4, can act on the cam rod 26 and cam plate 27 of the first cam assembly 21, and the cam rod 26 and cam plate 27 of the second cam assembly 22, thereby generating friction between the cam rod 26 and cam plate 27 in both cam assemblies, enabling the torque assembly to provide greater torque.

[0154] Understandably, the direction in which the cam plate of the second cam assembly applies force to the elastic element is opposite to the direction in which the baffle applies force to the elastic element. Therefore, the degree of compression of the elastic element will increase, and consequently, the frictional force generated by the cam rod and cam plate in the same cam assembly will also increase, thus enabling the torque assembly to provide greater torque.

[0155] In some embodiments, such as Figure 1 and Figure 4 As shown, the base frame 1 is provided with the torque component 2 and the rotation component 3 at both the first end and the second end along the first direction A; the rotation component 3 at the same end is disposed between the first cam component 21 and the second cam component 22 of the torque component 2 at the same end;

[0156] The hinge structure also includes:

[0157] Synchronization component 5 is connected between the torque component 2 at the first end and the torque component 2 at the second end, and is used to enable the rotation component 3 at the first end and the rotation component 3 at the second end to rotate synchronously and in opposite directions through the torque component 2 at the first end and the torque component 2 at the second end.

[0158] In this embodiment of the present disclosure, the torque component at the first end can provide torque during the rotation of the rotating component at the first end, so that the rotating component at the first end can be stably fixed in the required position.

[0159] Similarly, the torque component at the second end can provide torque during the rotation of the rotating component at the second end, so that the rotating component at the second end can be stably fixed in the desired position.

[0160] Thus, the torsion components at the first and second ends enable the hinge structure to fold better, thereby improving the user experience.

[0161] In this embodiment of the disclosure, such as Figure 5 As shown, the hinge structure also includes: a spring-loaded component 28 and a connecting plate 9. The connecting plate 9 is connected between the cam plate 27 of the second cam assembly 22 at the first end and the cam plate 27 of the second cam assembly 22 at the second end; the spring-loaded component 28 is disposed in the first direction A between the elastic element 25 of the torque assembly 2 at the first end and the elastic element 25 of the torque assembly 2 at the second end; and in the second direction B between the baffle 4 and the connecting plate 9. Both the spring-loaded component 28 and the elastic element 25 are compressed when the rotating assembly 3 rotates.

[0162] It should be noted that elastic components and elastic elements may include, but are not limited to, springs.

[0163] In this embodiment of the disclosure, the synchronization component is used to enable the rotation component at the first end and the rotation component at the second end to rotate synchronously and in opposite directions.

[0164] It should be noted that the synchronization component may include gears, and synchronous rotation is achieved through the meshing of gears. The synchronization component may also include sliders, and synchronous rotation is achieved through the limiting action between sliders. Of course, the synchronization component may also include other structures that can achieve synchronous rotation, and the embodiments disclosed herein are not limited thereto.

[0165] It is understood that in this embodiment of the present disclosure, the synchronization component acts on the rotation component through the torque component, thereby enabling the rotation component at the first end and the rotation component at the second end to rotate synchronously and in opposite directions.

[0166] In some embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, the synchronization component 5 includes:

[0167] The first synchronizing element 51 is connected to the cam rod 26 of the second cam assembly 22 at the first end;

[0168] The second synchronizing element 52 is connected to the cam rod 26 of the second cam assembly 22 at the second end;

[0169] The first synchronizing element 51 and the second synchronizing element 52 are engaged with each other.

[0170] In this embodiment of the disclosure, such as Figure 5 As shown, a first connecting rod is formed on the surface of the first synchronizing member 51 facing the connecting plate 9, and a second connecting rod is formed on the surface of the second synchronizing member 52 facing the connecting plate 9; the connecting plate 9 has a first accommodating space corresponding to the first connecting rod and a second accommodating space corresponding to the second connecting rod; the first connecting rod is located in the first accommodating space and can rotate around a second direction; the second connecting rod is located in the second accommodating space and can rotate around a second direction.

[0171] It should be noted that the extension directions of both the first and second connecting rods are parallel to the second direction. Both the first and second accommodating spaces can be formed by a groove in the connecting plate, or by a through hole in the connecting plate; this embodiment does not impose any limitations on this.

[0172] In this embodiment of the present disclosure, the first synchronizing element includes a first gear, and the cam rod of the second cam assembly at the first end has a first gear surface. The first synchronizing element is connected to the cam rod of the second cam assembly at the first end, including: the first gear and the teeth of the first gear surface meshing with each other.

[0173] The second synchronizing element includes a second gear, and the cam rod of the second cam assembly at the second end has a second gear surface. The second synchronizing element is connected to the cam rod of the second cam assembly at the second end, including: the teeth of the second gear and the second gear surface meshing with each other.

[0174] It should be noted that the first gear and the second gear can be synchronous gears. The meshing between the synchronous gears enables the synchronous and counter-rotating components at the first and second ends to rotate in opposite directions.

[0175] Understandably, by setting up the first and second synchronizing components, the rotating components at the first and second ends of the base frame are synchronized and rotate in opposite directions, thus improving the user experience.

[0176] In some embodiments, such as Figure 1 and Figure 2 As shown, the hinge structure also includes a fixing block 6;

[0177] The base frame 1 is provided with the fixing block 6 at both the first end and the second end along the first direction A;

[0178] The fixing block 6 is connected to the cam rod 26 of the first cam assembly 21, the cam rod 26 of the second cam assembly 22, and the rotating assembly 3, which are located at the same end.

[0179] The aforementioned fixed block is connected to the rotating component, and the rotating component will follow the fixed block when the fixed block moves.

[0180] In this embodiment of the disclosure, in the hinge structure used in an electronic device, a fixing block is used to fix the hinge structure to the first and second middle frames of the electronic device. For example, the fixing block can be fixed to the first and second middle frames respectively through screw holes and the threaded engagement of screws.

[0181] Understandably, by fixing the hinge structure to the electronic device using a fixing block, a better installation of the hinge structure into the electronic device is achieved.

[0182] In some embodiments, such as Figure 1 and 6 As shown, the hinge structure further includes:

[0183] The cover plate 7 is fixed to the base frame 1 and can cover the torque component 2 and part of the rotation component 3;

[0184] The cover plate 7 can serve as a screen support structure.

[0185] In this embodiment of the disclosure, such as Figure 6As shown, the hinge structure also includes a fastener 8, which fixes the cover plate 7 to the base frame 1.

[0186] Here, the fastener 8 can be used to fix the cover plate 7 to the base frame 1 by passing it through the fixing hole. For example, as... Figure 6 As shown, the fixing holes on the base frame 1 may include a first fixing hole 11, a second fixing hole 12 and a third fixing hole 13. The first fixing hole 11 may be disposed between the cam rod 26 of the first cam assembly 21 at the first end and the cam rod 26 of the second cam assembly 21 at the second end. The second fixing hole 12 may be disposed between the rotating assembly 3 at the first end and the rotating assembly 3 at the second end. The third fixing hole 13 may be disposed between the cam rod 26 of the second cam assembly 22 at the first end and the cam rod 26 of the second cam assembly 22 at the second end.

[0187] It should be noted that the cover plate also has alignment holes at the corresponding positions of the fixing holes on the base frame. The fasteners may include a first fixing screw corresponding to the first fixing hole, a second fixing screw corresponding to the second fixing hole, and a third fixing screw corresponding to the third fixing hole. By having the first fixing screw pass through the cover plate and the first fixing hole, the second fixing screw pass through the cover plate and the second fixing hole, and the third fixing screw pass through the cover plate and the third fixing hole, the cover plate is fixed to the base frame.

[0188] In this embodiment of the disclosure, the cover plate can serve as a screen support structure to support the screen.

[0189] It should be noted that the hinge structure may also include a floating plate connected to the rotating assembly. When the hinge structure is in the unfolded state, the cover plate, the floating plate connected to the rotating assembly at the first end, and the floating plate connected to the rotating assembly at the second end can be located on the same plane and work together to support the screen. When the hinge structure is in the folded state, the cover plate, the floating plate connected to the rotating assembly at the first end, and the rotating assembly at the second end can form a space to protect the screen.

[0190] It is understood that the cover plate in this embodiment can not only be used to cover the hinge structure as a protective cover plate, but also as a screen support structure to support the screen. In this way, the function of the cover plate can be enriched.

[0196] It is understood that the display module of this disclosure includes a hinge structure. By setting two cam assemblies at the end of the base frame, not only can the torque of the hinge structure be increased, but also the space of the hinge structure in the second direction can be utilized more rationally, thereby improving the space utilization rate of the hinge structure.
