These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0056] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0057] The hinge provided in the embodiment of the present application can be applied to electronic devices (for example, foldable display devices). Under different usage requirements, users can fold or unfold the foldable display device to meet different user needs. For example, when a user needs to carry a foldable display device with him, he can fold it to reduce its volume, thereby improving portability; when the user is using the foldable display device, he can unfold it to provide a larger display area and operation area, thereby improving convenience. In practical applications, the types of foldable display devices can be divided into many types, for example, they can be mobile phones, tablet computers, laptops, e-books, etc.

[0058] Taking a mobile phone as an example, the mobile phone may include a first shell and a second shell connected by a hinge. Under the action of the hinge, the first shell and the second shell can rotate relative to each other. The flexible screen can be set on the surface of the first shell and the second shell. When the mobile phone is unfolded, the flexible screen can provide a larger display area and operation area to improve the performance. When the mobile phone is folded, it is not only easy to carry, but also the folded flexible screen can be used. The following embodiment will describe the structure of the hinge in the foldable display device in detail.

[0059] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a hinge provided in an embodiment of the present application, Figure 2 The embodiment of this application provides Figure 1The hinge may include: a support base 100 , at least two flip components 200 and a torsion component 300 .

[0060] The support base 100 in the hinge may extend along a first direction X;

[0061] At least two flip assemblies 200 in the hinge are arranged relative to each other and can be rotatably connected to the support base 100. That is, a part of the flip assemblies of the at least two flip assemblies in the hinge are located on one side of the support base, and the other part of the flip assemblies are located on the other side of the support base. It should be noted that the following embodiments are schematically described by taking the two flip assemblies arranged relative to each other as an example. Here, when the two flip assemblies 200 in the hinge rotate relative to the support base 100 and the hinge is in an unfolded state, the two relatively arranged flip assemblies 200 can be distributed on both sides of the support base 100 in the second direction Y. It should be noted that when such a hinge is assembled into a folding display device, when the hinge is in an unfolded state, the side of the support base 100 in the hinge facing the flexible display panel (not shown in the figure) in the folding display device can be flush with the side of the flip assembly 200 facing the flexible display panel, so that the hinge can better support the folding display part in the flexible display panel.

[0062] The torsion assembly 300 in the hinge may include: a support shaft 301, and a first torsion piece 302, a second torsion piece 303 and an elastic element 304 sleeved on the support shaft 301. The support shaft 301 may be movably connected to the support base 100, the first torsion piece 302 and the second torsion piece 303 may be distributed along the first direction X, and the first torsion piece 302 and the second torsion piece 303 may both contact at least two flip assemblies 200.

[0063] The elastic element 304 can be configured to: apply a force to the first torsion member 302 and the second torsion member 303 at the same time. That is, the elastic element can apply a force to the first torsion member 302 and the second torsion member 303 at the same time, so that the first torsion member 302 and the second torsion member 303 can respectively apply an extrusion force to at least two oppositely arranged flip assemblies, thereby enabling the flip assembly in the hinge to have a torsion force during the flipping process. For example, the first torsion member 302 and the second torsion member 303 can be distributed on both sides of the two flip assemblies 200 in the first direction X. The elastic element 304 in the torsion assembly 300 can simultaneously apply a force toward the two flip assemblies 200 to the first torsion member 302 and the second torsion member 303.

[0064] In the embodiment of the present application, a support shaft 301 movably connected to the support seat 100 is provided in the torsion assembly 300, and the first torsion piece 302 and the second torsion piece 303 provided along the first direction X in the torsion assembly 300 are both in contact with the two flip assemblies provided oppositely, and the first torsion piece 302 and the second torsion piece 303 are both sleeved on the support shaft 301. In this way, the elastic element 304 can be used to apply a force to the first torsion piece 302 and the second torsion piece 303 at the same time, so that the two torsion pieces can apply an extrusion force to the flip assembly, and then can provide a damping force for the flip assembly 200 during the rotation process relative to the support seat 100, so as to realize the hovering function at different angles. In this way, by providing a group of elastic elements in the hinge and cooperating with the two torsion pieces, the torsion force when the hinge switches between unfolding and folding can be provided, so that the structure of the torsion assembly 300 in the hinge is relatively simple, and further the structure of the folding display device integrated with the hinge is relatively simple, and the user's use experience is improved.

[0065] In summary, the embodiment of the present application provides a hinge, which may include: a support seat, at least two flip assemblies and a torsion assembly. By setting a support shaft movably connected to the support seat in the torsion assembly, and the first torsion member and the second torsion member arranged along the first direction X in the torsion assembly are in contact with the two flip assemblies arranged oppositely, and the first torsion member and the second torsion member are both sleeved on the support shaft. In this way, the elastic element can be used to apply a force to the first torsion member and the second torsion member at the same time, so that the two torsion members can apply an extrusion force to the flip assembly, and then can provide a damping force for the flip assembly during the rotation process relative to the support seat, so as to realize the hovering function at different angles. In this way, by setting a group of elastic elements in the hinge and cooperating with the two torsion members, the torsion force when the hinge switches between unfolding and folding can be provided, so that the structure of the torsion assembly in the hinge is relatively simple, and further the structure of the folding display device integrated with the hinge is relatively simple, and the user's experience is improved.

[0066] In the examples of this application, please refer to Figure 3 , Figure 3It is a schematic diagram of the back side of a hinge provided by an embodiment of the present application. The first torque member 302 and the elastic element 304 in the torsion assembly 300 can be sleeved on the end near the first end of the support shaft 301, and the elastic element 304 can be located on the side of the first torque member 302 away from the flip assembly 200. One end of the elastic element 304 can abut against the first torque member 302, and the other end of the elastic element 304 can abut against the end of the first end of the support shaft 301. The end of the second end of the support shaft 301 can be connected to the second torque member 303. In this case, by setting the first torque member 302 and the elastic element 304 on the end of the first end of the support shaft 301, the second torque member 303 is set on the end of the second end of the support shaft 301, and the elastic element 304 abuts against the ends of the first torque member 302 and the first end of the support shaft 301, respectively. In this way, the elastic element 304 can apply a force to the end of the first end of the support shaft 301 while applying a force to the first torque member 302, so that the first end of the support shaft 301 can move slightly in a direction away from the first torque member 302, thereby enabling the second end of the support shaft 301 to apply a force to the second torque member 303. That is, the elastic element 304 can be set only on one side of the flip assembly 200, and the two torque members can be driven by the cooperation of the elastic element 304 and the support shaft 301. For example, the elastic element 304 can be a helical spring in a compressed state or a plurality of disc springs stacked, and the embodiment of the present application does not make specific limitations on this.

[0067] Optional, such as Figure 3 As shown, the torque assembly 300 may also include: a limiter 305, which may be mounted on the end of the first end of the support shaft 301, and the limiter 305 may abut against one end of the elastic element 304 away from the first torque member 302. In this case, the limiter 305 is mounted on the end of the first end of the support shaft 301, and the limiter 305 abuts against one end of the elastic element 304 away from the first torque member 302. In this way, the elastic element 304 can apply a force to the limiter 305, so that the limiter 305 drives the first end of the support shaft 301 to move in a direction away from the first torque member 302, thereby causing the second end of the support shaft 301 to apply a force to the second torque member 303. In addition, the limiter 305 can play a certain limiting role on the elastic element 304, thereby ensuring the connection stability between the elastic element 304 and the support shaft 301.

[0068] In the examples of this application, please refer to Figure 4 , Figure 4It is a partial structural exploded schematic diagram of a hinge provided in an embodiment of the present application. The end of the first end of the support shaft 301 in the hinge may have a first limiting groove a1, and the limiting member 305 may be snapped into the first limiting groove a1. In this case, by providing the first annular limiting groove a1 at the end of the first end of the support shaft 301, the limiting member 305 can be snapped into the first limiting groove a1, thereby ensuring the snapping stability of the limiting member 305 and the support shaft 301, and preventing the limiting member 305 from falling off the support shaft 301.

[0069] Optional, such as Figure 4 As shown, the end of the second end of the support shaft 301 in the hinge may have a limiting portion b1, and the limiting portion b1 may abut against the side of the second torque member 303 away from the flip assembly 200. In this case, by providing the limiting portion b1 at the end of the second end of the support shaft 301, the limiting portion b1 abuts against the side of the second torque member 303 away from the flip assembly 200. In this way, when the elastic element 304 applies a force to the end of the first end of the support shaft 301, the limiting portion b1 on the end of the second end of the support shaft 301 can stably abut against the side of the second torque member 303 away from the flip assembly 200. In the present application, the side of the second torque member 303 in the torsion assembly 300 away from the flip assembly 200 may have a second limiting groove b2, and at least a portion of the limiting portion b1 provided at the end of the second end of the support shaft 301 may be located in the second limiting groove b2. In this way, by limiting the limiting portion b1 provided at the end of the second end of the support shaft 301 in the second limiting groove b2 on the second torque member 303, the connection stability between the second torque member 303 and the end of the second end of the support shaft 301 is further improved. For example, the limiting portion b1 can be a limiting protrusion, and at least a portion of the limiting protrusion can be located in the second limiting groove b2.

[0070] In the embodiments of the present application, Figure 3 and Figure 4 As shown, the stopper 305 may have a snap-in groove c1, and the stopper 305 may be snap-in on the end of the first end of the support shaft 301 through the snap-in groove c1. The torque assembly 300 may also include: a blocking member 306 sleeved on the support shaft 301, the blocking member 306 may be located between the elastic element 304 and the stopper 305, one side of the blocking member 306 may abut against the side of the stopper 305 facing the elastic element 304, and the other side of the blocking member 306 may abut against the end of the elastic element 304 away from the flip assembly 200. In this case, the stopper 305 is snap-in with the end of the first end of the support shaft 301 by setting the snap-in groove c1, and the blocking member 306 set between the stopper 305 and the elastic element 304 can further ensure the effective position limitation of the elastic element 304, and ensure that the elastic element 304 will not fall off the support shaft 301.

[0071] Optional, such as Figure 3 As shown, the torsion assembly 300 in the hinge provided by the present application may include at least two support shafts 301, and at least two support shafts 301 may be respectively connected to at least two flip assemblies 200 arranged oppositely. Among them, the first torsion member 302, the second torsion member 303 and the blocking member 306 may be simultaneously sleeved on at least two support shafts 301, and each support shaft 301 is sleeved with an elastic element 304. For example, in the present application, two support shafts 301 are taken as an example, and the two support shafts are respectively connected to two flip assemblies arranged oppositely. In this case, by arranging two support shafts 301 in the torsion assembly 300, an elastic element 304 is sleeved on each support shaft 301, and the first torsion member 302 and the second torsion member 303 are also sleeved on the two support shafts 301. In this way, the elastic elements 304 arranged on different support shafts 301 can apply a force to the first torsion member 302 and the second torsion member 303, ensuring that the torsion effect of the hinge during folding and unfolding is better. It should be noted that the support shaft 301 in the embodiment of the present application may not rotate relative to the support seat 100. After the second torque member 303 is simultaneously sleeved on the two support shafts 301, it can be connected with the end of the second end of the support shaft 301 by interference fit to ensure the stability of the support shaft 301.

[0072] In the embodiments of the present application, Figure 3 As shown, the torsion assembly 300 may also include: at least one auxiliary elastic element 307 located between at least two support shafts 301, and the auxiliary elastic element 307 may be distributed between the first torsion member 302 and the blocking member 306. In this case, the auxiliary elastic element 307 is arranged between the two support shafts 301, and the two ends of the auxiliary elastic element 307 are respectively abutted against the first torsion member 302 and the blocking member 306. In this way, the auxiliary elastic element 307 can further apply a force to the first torsion member 302 and the second torsion member 303, further ensuring that the torsion effect of the hinge during the folding and unfolding process is better. It should be noted that the structure of the auxiliary elastic element 307 can refer to the description of the elastic element in the above, and will not be repeated here.

[0073] Optional, please refer to Figure 5 , Figure 5It is a partial structural exploded schematic diagram of another hinge provided by an embodiment of the present application. The flip assembly 200 may include: a first drive rod 201, a second drive rod 202, a transfer fixture 203 and a flip plate 204. One end of the first drive rod 201 and one end of the second drive rod 202 can be sleeved on the support shaft 301, the other end of the first drive rod 201 and the other end of the second drive rod 202 can be slidably connected to the transfer fixture 203, and one side of the flip plate 204 can be movably connected to the transfer fixture 203. Among them, the part of the first drive rod 201 sleeved on the support shaft 301 can abut against the first torque member 302; the part of the second drive rod 202 sleeved on the support shaft 301 can abut against the second torque member 303. For example, the structures of at least two flip assemblies arranged relatively to each other can be the same, and the structure of the flip assembly can refer to the description in the above. It should be noted that one side of the flip plate 204 can be used to be attached to the back of the flexible display panel in the folding display device, and the adapter fixture 203 can be used to be fixedly connected to the housing in the folding display device. For example, a flip assembly 200 is used as an example to schematically illustrate the movement process of the flip assembly: when the hinge switches from the unfolded state to the folded state, under the action of external force, the adapter fixture 203 fixedly connected to the housing in the folding display device can rotate in a clockwise direction. At this time, the adapter fixture 203 can simultaneously drive one end of the first drive rod 201 and the second drive rod 202 to rotate in the same direction; the other end of the first drive rod 201 and the second drive rod 202 can rotate around the support shaft 301, and during the rotation process, the resistance between the first drive rod 201 and the first torsion member 302, and the resistance between the second drive rod 202 and the second torsion member 303 are both provided for the hinge to provide a damping effect during the folding process. In addition, during the folding process, the flip plate 204 can provide good support for the flexible display panel in the folding display device. It should be noted that, in this case, the hinge can be in a "water drop" shape, also known as a water drop type hinge.

[0074] Please refer to Figure 6 and Figure 7 , Figure 6 is a schematic diagram of the effect of a hinge in a folded state provided by an embodiment of the present application, Figure 7This is a schematic diagram of the effect of a hinge in an unfolded state provided by an embodiment of the present application. When the hinge switches from a folded state to an unfolded state, under the action of an external force, the adapter fixture 203 fixedly connected to the housing in the folding display device can rotate in a counterclockwise direction. At this time, the adapter fixture 203 can simultaneously drive one end of the first drive rod 201 and the second drive rod 202 to rotate in the same direction; the other ends of the first drive rod 201 and the second drive rod 202 can rotate around the support shaft, and during the rotation process, the resistance between the first drive rod 201 and the first torsion member 302, and the resistance between the second drive rod 202 and the second torsion member 303 both provide a damping effect for the hinge during the unfolding process. In addition, when the hinge is unfolded to the final state (i.e., the angle between the two flip plates in the two flip assemblies is 180 degrees), the two flip plates 204 in the two flip assemblies 200 are coplanar with one side close to the flexible display panel, that is, the two flip plates 204 in the two flip assemblies 200 are close to the flexible display panel. The side can form a flat support surface, and therefore, it can provide good support for the flexible screen. It should be noted that the two flip assemblies 200 can be symmetrically arranged relative to the support base 100, and the basic structural composition and movement principle of the other flip assembly 200 can be the same as the flip assembly described above. Therefore, in the embodiment of the present application, the structural composition and movement principle of the other flip assembly can refer to the above description of the first flip assembly, and will not be repeated here.

[0075] For example, Figure 4 and Figure 5 As shown, the side of the transfer fixture 203 facing away from the flip plate 204 may have two linear slide grooves d1, the other end of the first driving rod 201 may be located in one linear slide groove d1, and may be slidably connected to the transfer fixture 203; the other end of the second driving rod 202 may be located in another linear slide groove d1, and may be slidably connected to the transfer fixture 203. In the present application, the side of the transfer fixture 203 may have an arcuate slide groove d2, and the side of the flip plate 204 facing away from the flexible display panel may have an arcuate slider 2041 matching the shape of the arcuate slide groove d2, and the arcuate slider 2041 can slide in the arcuate slide groove d2.

[0076] In the embodiment of the present application, the portion of the first drive rod 201 that is sleeved on the support shaft 301 may have a plurality of first abutment portions A1 on the side facing the first torque member 302, and the first torque member 302 may have a plurality of second abutment portions B1 on the side facing the first drive rod 201. And / or, the portion of the second drive rod 202 that is sleeved on the support shaft 301 may have a plurality of third abutment portions A2 on the side facing the second torque member 303, and the second torque member 303 may have a plurality of fourth abutment portions B2 on the side facing the second drive rod. For example, one of the first abutment portion and the second abutment portion may be a protrusion, and the other may be a recessed portion; one of the third abutment portion and the fourth abutment portion may be a protrusion, and the other may be a recessed portion. Figure 3 As shown, the part of the first driving rod 201 sleeved on the support shaft 301 may have a plurality of first protrusions on the side facing the first torsion member 302, and the first torsion member 302 may have a plurality of first recesses on the side facing the first driving rod 201. And / or, the part of the second driving rod 202 sleeved on the support shaft 301 may have a plurality of second protrusions on the side facing the second torsion member 303, and the second torsion member 303 may have a plurality of second recesses on the side facing the second driving rod 202. For example, taking the plurality of first protrusions on the first driving rod 201 and the plurality of first recesses on the first torsion member 302 as an example, when the hinge is in a fully extended state, the first protrusion on the first driving rod 201 may be located in the first recess on the first torsion member 302, so that the hinge can maintain the specific angle, and when the user touches or presses the flexible screen, the display device will not be easily folded under the action of external force. When the hinge is in a fully folded state, the first protrusion on the first driving rod 201 can be located in the first recessed portion on the first torsion member 302, so that the hinge can maintain the specific angle. When the user touches or presses the flexible screen, the display device will not be randomly unfolded under the action of external force, thereby ensuring the safety of the display device. It should be noted that the hinge can also be suspended at any position between fully unfolded and fully folded by the cooperation of multiple first protrusions and multiple first recessed portions.

[0077] Optional, such as Figure 4 and Figure 5As shown, the flip assembly 200 may further include: a swing arm 205 and a first transition piece 206, one end of the swing arm 205 may be rotatably connected to the support base 100, the other end of the swing arm 205 may be rotatably connected to one end of the first transition piece 206, and the other end of the first transition piece 206 may be rotatably connected to the transfer fixture 203. In this case, by providing the first transition piece 206 between the swing arm 205 and the transfer fixture 203 in the flip assembly 200, it is equivalent to increasing the number of connecting rods in the connecting rod system composed of the support base, the swing arm, the transfer fixture and the driving rod, so that when the hinge switches between the folded state and the unfolded state, the operation of the flip assembly 200 is more reliable, and the folding life of the folding display device integrated with the hinge is effectively improved. For example, when the hinge switches from an unfolded state to a folded state, under the action of external force, the adapter fixture 203 fixedly connected to the casing in the folding display device can rotate in a clockwise direction, and at the same time, the adapter fixture 203 can drive the first transition piece 206 to rotate in the same direction, and then can drive the swing arm 205 to rotate relative to the support base 100, so that the flip assembly 200 can achieve multi-stage linkage.

[0078] In this application, if Figure 4 and Figure 5 As shown, the end of the swing arm 205 away from the support seat 100 may have a first connection hole e1, the end of the first transition piece 206 may have a second connection hole e2, and the other end of the first transition piece 206 may have a third connection hole e3. The flip assembly 200 may also include: a first connection shaft 207 and a second connection shaft 208. Among them, the end of the swing arm 205 in the flip assembly 200 away from the support seat 100 may be sleeved on the first connection shaft 207 through the first connection hole e1, and one end of the first transition piece 206 may be sleeved on the first connection shaft 207 through the second connection hole e2. The other end of the first transition piece 206 may be sleeved on the second connection shaft 208 through the third connection hole e3, and the second connection shaft 208 may be fixedly connected to the adapter fixing member 203.

[0079] In the embodiments of the present application, Figure 4 and Figure 5As shown, the flip assembly 200 may further include: a second transition piece 209, one end of which may be rotatably connected to one end of the swing arm 205 away from the support seat 100 and one end of the first transition piece 206 away from the transfer fixing piece 203 at the same time; the other end of the second transition piece 209 may be rotatably connected to the first drive rod 201 and the second drive rod 202 at the same time. In this case, by providing the second transition piece 209 in the flip assembly 200, one end of the second transition piece 209 may be rotatably connected to one end of the swing arm 205 away from the support seat 100 and one end of the first transition piece 206 away from the transfer fixing piece 203 at the same time, and the other end of the second transition piece 209 may be rotatably connected to the first drive rod 201 and the second drive rod 202 at the same time. In this way, by respectively rotating the second transition piece 209 with the drive rod and the first transition piece 206, it is possible to limit the redundant degrees of freedom of the first transition piece, the swing arm and the adapter fixing piece, thereby making the operation of the flip assembly more stable and ensuring the consistency of the running trajectory of the hinge when switching between the folded state and the unfolded state.

[0080] In this application, if Figure 4 and Figure 5 As shown, one end of the second transition piece 209 may have a fourth connection hole e4, and the other end of the second transition piece may have a fifth connection hole e5; the first drive rod 201 may have a sixth connection hole e6, and the second drive rod 202 may have a seventh connection hole e7. The flip assembly 200 may also include: a third connection shaft 210. Among them, one end of the second transition piece 209 may be sleeved on the second connection shaft 208 through the fourth connection hole e4, and the other end of the second transition piece 209 may be sleeved on the third connection shaft 210 through the fifth connection hole e5; the first drive rod 201 may be sleeved on the third connection shaft 210 through the sixth connection hole e6, and the second drive rod 202 may be sleeved on the third connection shaft 210 through the seventh connection hole e7.

[0081] Optional, please refer to Figure 3 , Figure 8 and Fig. 9 , Figure 8 is a partial structural diagram of another hinge provided in an embodiment of the present application, Fig. 9It is a cross-sectional view of a hinge provided in an embodiment of the present application. The support seat 100 in the hinge may have an arc-shaped slot 101 on one side facing the flip assembly 200, and one end of the swing arm 205 may have an arc-shaped slider 2051. The arc-shaped slider 2051 on one end of the swing arm 205 may be located in the arc-shaped slot 101 in the support seat 100, and may be rotatably connected to the support seat 100. In this way, by assembling the arc-shaped slider 2051 in the arc-shaped slot 101, the swing arm 205 and the support seat 100 can be rotatably connected. In addition, through the virtual axis connection method, the arc-shaped slider 2051 can be well hidden to prevent exposure, thereby increasing the visual integrity of the hinge. For example, the hinge may also include: a pressure plate 400, which may be fixedly connected to one side of the support seat 100 where the arc-shaped slot 101 is set. Among them, when the hinge is in the unfolded state, the side of the pressing plate 400 facing away from the support seat 100 can be coplanar with the front sides of the two flip plates 204. In this case, the arc-shaped slider 2051 can be limited in the arc-shaped slide groove 101 by the pressing plate 400, so as to achieve a stable connection between the arc-shaped slider 2051 and the arc-shaped slide groove 101. In addition, when the hinge is unfolded to the final state, the pressing plate 400 and the two flip plates 204 can form a flat supporting surface. In this way, a good supporting effect can be provided for the flexible screen in the display device.

[0082] In the embodiment of the present application, the positional relationship between the support shaft 301 and the support base 100 when the support shaft 301 penetrates the support base 100 along the first direction is schematically described by taking the following two optional implementation methods as examples:

[0083] The first optional implementation method is Figure 8 and Fig. 9 As shown, the support seat 100 may have a through hole 102 for the support shaft 301 to pass through, and the through hole 102 may include: a first hole area f1 connected to the arc-shaped slide groove 101 in the support seat 100, and a second hole area (not shown in the figure) distributed on at least one side of the first hole area f1. Among them, the part of the support shaft 301 located in the first hole area f1 of the through hole 102 has an avoidance groove 301a. In this case, by providing the avoidance groove 301a in the part of the support shaft 301 located in the first hole area f1, the support shaft 301 will not protrude into the arc-shaped slide groove 101, ensuring that the arc-shaped slider 2051 can slide stably in the arc-shaped slide groove 101 without being disturbed by the support shaft. For example, the second hole area can be distributed on both sides of the first hole area f1 to increase the stability of the rotational connection between the flip assembly and the support shaft.

[0084] For the second optional implementation, please refer to Fig.10 and Fig.11 , Fig.10 is a partial structural diagram of another hinge provided in an embodiment of the present application. Fig.11 yes Fig.10 The cross-sectional view of the hinge shown. The side of the support base 100 facing the flip assembly 200 may have an arc-shaped slide groove, and the side of the support base 100 away from the arc-shaped slide groove 101 may have a mounting groove 103. The support shaft 301 may include: a first shaft body C1 and a second shaft body C2, and a transition piece C3 located between the first shaft body C1 and the second shaft body C2, and the transition piece C3 may be fixed in the mounting groove 103. One end of the first shaft body C1 may be fixedly connected to one end of the transition piece C3, and one end of the second shaft body C2 may be fixedly connected to the other end of the transition piece C3. Among them, the first torque member 302 may be sleeved on the first shaft body C1, and the second torque member 303 may be sleeved on the second shaft body C2. In this way, by providing the mounting groove 103 on the side of the support base 100 away from the arc-shaped slide groove 101, the support shaft 301 is configured as the first shaft body C1, the second shaft body C2 and the transition piece C3 connected to each other. In this way, the arc-shaped slide groove 101 area can be avoided through the installation groove 103, and the first shaft body C1 transmits the force to the second shaft body C2 through the adapter C3 installed in the installation groove 103. For example, the side surface of the support seat 100 has a first through hole f2 and a second through hole f3, respectively, and the first shaft body C1 can pass through the first through hole f2 and be fixedly connected to the adapter C3 in the installation groove 103; the second shaft body C2 can pass through the second through hole f3 and be fixedly connected to the adapter C3 in the installation groove 103.

[0085] In order to ensure that at least two flip assemblies arranged opposite to each other can move synchronously during the folding or unfolding process of the hinge, the present application provides a synchronization mechanism that can realize the synchronous rotation toward each other and the synchronous rotation away from each other between the flip assemblies. Figure 8 and Fig.10 As shown, the hinge may also include: a synchronization mechanism 500, which may be connected to the first drive rods 201 in at least two flip assemblies 200 arranged opposite to each other. Here, two flip assemblies arranged opposite to each other are taken as an example, and the synchronization mechanism 500 may include: two first synchronization members 501, which may be connected to the first drive rods 201 in the two flip assemblies 200 respectively, and the two first synchronization members 501 may be engaged and connected. In this way, when the first drive rod 201 in one flip assembly rotates, it drives a first synchronization member 501 arranged adjacent to it to rotate; this first synchronization member 501 transmits power to another first synchronization member 501; and then drives the first drive rod 201 in another flip assembly 200 to rotate.

[0086] In the present application, the synchronization mechanism 500 may further include: two second synchronization members 502 located between the two first synchronization members 501. Here, the second synchronization member 502 may include: a second synchronization shaft 502a connected to the support seat 100, and a second synchronization wheel 502b sleeved on the second synchronization shaft 502a. In one possible case, the second synchronization shaft 502a may be fixedly connected to the support seat 100, and the second synchronization wheel 502b may be able to rotate on the second synchronization shaft 502a. In another possible case, the second synchronization shaft 502a may be rotationally connected to the support seat 100, and the second synchronization wheel 502b may be fixedly connected to the second synchronization shaft 502a, and the second synchronization wheel 502b may be able to rotate synchronously with the second synchronization shaft 502a. Among them, the second synchronization wheel 502b in the second synchronization member 502 may mesh with the outer teeth on the adjacent first synchronization member 501, and the two second synchronization wheels 502b in the two second synchronization members 502 located between the two first synchronization members 501 mesh.

[0087] In summary, the embodiment of the present application provides a hinge, which may include: a support seat, at least two flip assemblies and a torsion assembly. By setting a support shaft movably connected to the support seat in the torsion assembly, and the first torsion member and the second torsion member arranged along the first direction X in the torsion assembly are in contact with the two flip assemblies arranged oppositely, and the first torsion member and the second torsion member are both sleeved on the support shaft. In this way, the elastic element can be used to apply a force to the first torsion member and the second torsion member at the same time, so that the two torsion members can apply an extrusion force to the flip assembly, and then can provide a damping force for the flip assembly during the rotation process relative to the support seat, so as to realize the hovering function at different angles. In this way, by setting a group of elastic elements in the hinge and cooperating with the two torsion members, the torsion force when the hinge switches between unfolding and folding can be provided, so that the structure of the torsion assembly in the hinge is relatively simple, and further the structure of the folding display device integrated with the hinge is relatively simple, and the user's experience is improved.

[0088] The embodiment of the present application also provides an electronic device, which may include: a flexible display panel (not shown in the figure), at least two housings (not shown in the figure) and a hinge. The at least two housings may be connected by a hinge, and the flexible display panel may be covered on the at least two housings. In this way, the housing may be unfolded or folded by the hinge, and the housing may drive the flexible display panel to unfold or fold. For example, the housing may be fixedly connected to the transfer fixture in the hinge.

[0089] The embodiment of the present application also provides an accessory of an electronic device, and the accessory of the electronic device may include: at least two protective covers (not shown in the figure) and a hinge, and the at least two protective covers may be connected to the hinge. For example, the hinge may be the hinge provided in the above embodiment. In this way, the at least two protective covers may be sleeved on at least two housings in the electronic device to protect the electronic device.

[0091] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
