[0034] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0035] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the folding device of the present application. In the description of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0036] In order to better understand this application, Figures 1 to 5 The folding device and the display device of the embodiments of the present application are described in detail.

[0037] See also Figures 1 to 3 A folding device 100 provided in an embodiment of the present application includes a folding portion 10, which is used to connect with a component to be folded. The folding portion 10 can rotate to drive the component to be folded to a predetermined position, wherein the folding portion 10 includes a fixing member 1, a rotating shaft 2 and a telescopic assembly, wherein the fixing member 1 has a accommodating cavity 101, the rotating shaft 2 is arranged in the accommodating cavity 101 and passes through the fixing member 1 along its own axial direction X, and the telescopic assembly includes two or more telescopic members 3 arranged at intervals along the circumferential direction Z of the rotating shaft 2, one end of each telescopic member 3 is connected to the rotating shaft 2 and the other end abuts against the inner wall of the fixing member 1, wherein the rotating shaft 2 can rotate around its own axis and drive the telescopic assembly to rotate relative to the fixing member 1, and when rotated to the predetermined position, the telescopic assembly abuts against the fixing member 1 to make the rotating shaft 2 stationary.

[0038] The folding device 100 in the embodiment of the present application can be arranged between two screens of a foldable electronic product, so that the two screens can be folded in half with the folding device 100 as the center and either screen can be fixedly suspended. For example, it can be applied to a foldable screen mobile phone.

[0039] Optionally, the component to be folded may be a display screen, and the folding device 100 is connected to the component to be folded via the folding portion 10 thereof and drives the component to be folded to rotate to any angle and then hover.

[0040] The fixing part 1 in the folding portion 10 has a accommodating cavity 101. It can be understood that the fixing part 1 is a hollow structure. Optionally, the fixing part 1 can be set to a cylindrical structure. After passing through along its own axis, the middle part forms an accommodating cavity 101. The present application does not specifically limit the specific structural shape of the fixing part 1.

[0041] Optionally, the accommodating cavity 101 has a columnar structure, and its inner wall contour is an arc shape, and the arc of the inner wall contour may be discontinuous, and its radius size, concave and convex orientation, and extension length may be adjusted to be different from each other, and may be set into multiple types and connected in succession. The present application does not specifically limit the specific structure of the accommodating cavity 101.

[0042] The rotating shaft 2 is passed through the accommodating cavity 101 of the fixing member 1 along its own axial direction X, so that both ends of the rotating shaft 2 are exposed, and can be used to connect the components to be folded. The rotating shaft 2 can rotate clockwise or counterclockwise in the accommodating cavity 101, and can be driven to rotate manually.

[0043] A telescopic assembly is arranged between the rotating shaft 2 and the inner wall of the fixing member 1, and the telescopic assembly specifically includes a plurality of telescopic members 3, one end of each telescopic member 3 is connected to the rotating shaft 2 and the other end abuts against the inner wall of the fixing member 1, so as to connect the rotating shaft 2 with the fixing member 1. No matter where the telescopic member 3 abuts against the inner wall, it is necessary to ensure that the telescopic member 3 is at least in a compressed state so that it forms a reaction force acting on the rotating shaft 2.

[0044] Optionally, the telescopic part in the telescopic member 3 can be a structure such as a telescopic column, which can play the role of telescopic and supporting. The elastic part sleeved on the telescopic part can adopt a damping mechanism such as a spring. Both are telescopic, so they can perform telescopic reciprocating motion together in the accommodating cavity 101, providing a balancing force for the fixed hovering of the rotating shaft 2.

[0045] Since the multiple telescopic members 3 are capable of generating a reaction force to act on the rotating shaft 2 , when the rotating shaft 2 rotates to a predetermined position, the multiple telescopic members 3 cooperate with each other to fix the rotating shaft 2 in the accommodating cavity 101 of the fixing member 1 .

[0046] Optionally, multiple telescopic parts 3 are distributed at intervals along the circumferential direction Z of the rotating shaft 2, so that the rotating shaft 2 can be subjected to force at multiple angles in the circumferential direction Z, so that it can be balanced and fixed in the accommodating cavity 101. The more telescopic parts 3 are provided, the better the balance stability of the rotating shaft 2 in the accommodating cavity 101. The present application does not specifically limit the specific number of telescopic parts 3.

[0047] Since one end of the telescopic part 3 is connected to the rotating shaft 2, the telescopic part 3 can rotate along with the rotating shaft 2, and the other end of the telescopic part 3 abuts against the inner wall of the fixed part 1, which can be understood as a movable contact. The other end of the telescopic part 3 can rotate relative to the inner wall of the fixed part 1 and form sliding friction. Here, it is necessary to control the formation of a smaller sliding friction between the two to facilitate the rotation of the telescopic part 3.

[0048] While the rotating shaft 2 drives the telescopic part 3 to rotate, the telescopic part 3 is also compressed by the inner wall of the fixed part 1, forming a reaction force acting on the rotating shaft 2. However, since the driving force on the rotating shaft 2 in the circumferential direction Z can overcome the multi-directional reaction forces of the telescopic components and control and reduce the above-mentioned sliding friction, the rotating shaft 2 can still be easily rotated manually.

[0049] A folding device 100 is provided in an embodiment of the present application, wherein the folding portion 10 can realize the connection between the rotating shaft 2 and the fixing member 1 through a telescopic component arranged between the rotating shaft 2 and the fixing member 1, and can also utilize the reverse force provided by the fixing member 1 to the telescopic component to act on the rotating shaft 2, thereby squeezing the rotating shaft 2 from multiple angles to make it stop and be fixed in a predetermined position. Since the rotating shaft 2 is connected to the part to be folded, while the rotating shaft 2 drives the part to be folded to rotate at any angle, it realizes fixed hovering of the part to be folded at a certain angle, thereby improving the user experience and meeting the user's demand for fixed hovering of the folding part.

[0050] As an optional embodiment, please continue to refer to Figures 1 to 3 There are two folding parts 10, and the rotating shafts 2 of the two folding parts 10 are arranged at intervals and in parallel. The folding device 100 also includes a connecting part 20, and the two folding parts 10 are connected by the connecting part 20. The rotating shaft 2 of any folding part 10 can rotate relative to the rotating shaft 2 of the other folding part 10.

[0051] The folding part 10 as described above can be provided in two, and the respective rotating shafts 2 of the two folding parts 10 are provided in parallel and kept at a certain distance to avoid mutual interference caused by structural interference between the two parts.

[0052] Optionally, the two folding parts 10 can be connected into a whole through the connecting part 20 to facilitate the overall control thereof. The spacing distance between the two folding parts 10 should not be too large to reduce the gap formed.

[0053] The present application does not impose any special limitation on the specific structure and connection method of the connecting portion 20 , as long as the two folding portions 10 are connected into a whole.

[0054] The rotating shaft 2 of any folding portion 10 can rotate relative to the rotating shaft 2 of the other folding portion 10 . For example, one of the rotating shafts 2 can be rotated while the other rotating shaft 2 remains stationary.

[0055] Optionally, the two rotating shafts 2 can also rotate simultaneously, and can rotate clockwise or counterclockwise. The rotation direction and rotation speed of both can be adjusted manually so that the two can rotate relative to each other to form different hovering angles to meet different adjustment requirements.

[0056] A folding device 100 provided in an embodiment of the present application can control the adjustment at the same time by setting two folding parts 10 in the folding device 100, has multiple adjustment methods and adapts to working conditions, realizes two-way adjustment of the folding parts, improves the flexibility of adjustment, and can further form more hovering states on the basis of completing hovering, thereby meeting more hovering needs of users.

[0057] As an alternative embodiment, see Figure 3 The connecting portion 20 includes a connecting belt 21, which surrounds and covers at least part of the two fixing members 1 along the radial direction Y of the rotating shaft 2 to connect the two folding portions 10, and the two fixing members 1 are arranged at intervals in the connecting belt 21 along the radial direction Y.

[0058] Optionally, the connecting portion 20 may adopt a connecting belt 21, which is a ring-shaped closed structure. The connecting belt 21 is used to wrap the fixing parts 1 of the two folding portions 10 in the radial direction Y. Part of the surface of the two fixing parts 1 is wrapped by the wrapped connecting belt 21 and forms a contact connection, so that the two folding portions 10 and the connecting portion 20 form an integral structure.

[0059] Since the two fixing members 1 are both stationary, they can maintain a certain distance between each other in the radial direction Y in the connecting belt 21 , or they can be in appropriate contact with each other to reduce the distance between the two folded portions 10 .

[0060] The connection part 20 in the present application is not limited to the connection belt 21 structure, and can also be a connection rod, a connection plate or other structures, or two fixing parts 1 are directly in contact and connected to form an integrated structure, as long as the two folding parts 10 can form a whole. The present application does not make any special limitation on the specific structure of the connection part 20.

[0061] The embodiment of the present application provides a folding device 100, in which the connecting part 20 adopts the structure of a connecting belt 21, which provides a feasible connection method. While connecting the two folding parts 10 to form an integral structure, the structure is also wrapped to ensure that the internal rotation is not affected by the outside world, forming a certain isolation protection, which is beneficial to extending the service life of the folding device 100.

[0062] As an alternative embodiment, see Figure 4 and Figure 5 The telescopic members 3 are arranged in pairs, and the telescopic members 3 arranged in pairs are symmetrically distributed with the rotating shaft 2 as the center.

[0063] Optionally, the telescopic members 3 are arranged in pairs, from which it can be seen that the total number of the telescopic members 3 is an even number, and the present application does not impose any special limitation on the specific number of pairs of the telescopic members 3 .

[0064] Each pair of telescopic parts 3 is symmetrically distributed with the rotating shaft 2 as the center. In a pair of telescopic parts 3, the forces exerted on the rotating shaft 2 by a single telescopic part 3 are opposite. In this way, the forces exerted on the rotating shaft 2 by each pair of telescopic parts 3 can be balanced with each other, so that the rotating shaft 2 can remain stationary in the accommodating cavity 101.

[0065] The telescopic members 3 arranged in pairs can be located at any angular position on the circumferential direction Z of the rotating shaft 2. Multiple pairs of telescopic members 3 arranged in this way can balance the rotating shaft 2 at multiple angles of the rotating shaft 2, further improving the stability of the rotating shaft 2.

[0066] A folding device 100 provided in an embodiment of the present application provides the rotating shaft 2 with better balancing performance by arranging the telescopic parts 3 in pairs and distributing them symmetrically around the rotating shaft 2, thereby avoiding deviation of the rotating shaft 2 during rotation and improving the stability of the rotating shaft 2 when it is stationary and in operation.

[0067] As an optional embodiment, please continue to refer to Figure 4 and Figure 5 The inner wall of the fixing member 1 has alternately arranged recesses 11 and protrusions 12 , the recesses 11 are recessed toward the shaft 2 , and the protrusions 12 are protruded toward the shaft 2 , and the telescopic member 3 is compressed when passing through the protrusions 12 and stretched when passing through the recesses 11 .

[0068] The inner wall of the fixing member 1 in this embodiment has an irregular contour, which can be set to an arc-shaped contour, and only the local direction is adjusted to form an alternating structure with concave parts 11 and convex parts 12.

[0069] The recessed portion 11 is sunken toward the shaft 2, which can be understood as a local hollowing out of the inner wall of the fixing member 1, while the convex portion 12 is convex toward the shaft 2, which can be understood as a local raising of the inner wall of the fixing member 1. Such alternating arrangement makes the inner wall of the fixing member 1 have an uneven structure.

[0070] Optionally, the concave portion 11 and the convex portion 12 on the inner wall of the fixing member 1 may have different arc lengths and radii in addition to being oriented in different directions, so that the radial Y distances from the central rotating shaft 2 to the inner wall of the fixing member 1 are different.

[0071] It can be understood that the concave portions 11 and the convex portions 12 of the inner wall of the fixing member 1 are alternately distributed successively along the circumferential direction Z, thereby forming a petal-shaped inner wall.

[0072] When the telescopic member 3 abuts against the inner wall of the fixing member 1 and rotates, the telescopic member 3 is always in a reciprocating state of compression and extension due to the uneven petal-shaped inner wall, and has contraction elasticity.

[0073] When the telescopic member 3 passes through the convex portion 12 of the inner wall, the radial Y distance from the rotating shaft 2 to the inner wall is reduced, so that the convex portion 12 compresses the telescopic member 3, and the telescopic member 3 gradually enters a compressed state; when the telescopic member 3 passes through the concave portion 11 of the inner wall, the radial Y distance from the rotating shaft 2 to the inner wall is increased, so that the telescopic member 3 gradually enters an extended state.

[0074] The telescopic member 3 gradually stretches when passing through the recess 11 of the inner wall. This stretching process is only relative to the stretching when passing through the convex portion 12. The telescopic member 3 is still compressed as a whole when passing through the recess 11, and a reverse elastic force is always applied to the shaft 2 to ensure the balance and fixation of the shaft 2.

[0075] When the telescopic member 3 rotates in the uneven inner wall, it is more necessary to reduce the sliding friction between the telescopic member 3 and the inner wall, so that the telescopic member 3 can smoothly transition in the inner wall where the concave parts 11 and the convex parts 12 are alternately distributed.

[0076] A folding device 100 provided in an embodiment of the present application, by setting the inner wall of the fixing part 1 to a petal-shaped profile with a recessed portion 11 and a protruding portion 12, can enable the rotating telescopic part 3 to always be in a state of telescopic reciprocating motion, thereby continuously providing a reaction force to the rotating shaft 2, dynamically maintaining the balanced suspension of the rotating shaft 2, and forming a buffering protection for the rotating shaft 2. At the same time, the telescopic property of the telescopic part 3 can adapt to the inner wall structure of different profiles, can be used in more rotating environments, and has better application adaptability.

[0077] As an optional embodiment, please continue to refer to Figure 4 and Figure 5 Each telescopic member 3 in the telescopic assembly is arranged on the rotating shaft 2 at intervals corresponding to the concave portion 11 and / or the convex portion 12 .

[0078] The specific position of the telescopic member 3 on the shaft 2 can be determined corresponding to the inner wall profile of the fixing member 1 , for example, the concave portion 11 and / or the convex portion 12 of the telescopic member 3 corresponding to the inner wall is connected to the shaft 2 .

[0079] Optionally, the telescopic member 3 can be arranged on the shaft 2 only corresponding to the recessed portion 11 of the inner wall. When stationary, one end of each telescopic member 3 in the telescopic assembly is first connected to the shaft 2, and the other end thereof is respectively abutted against each recessed portion 11 on the inner wall.

[0080] Similarly, when stationary, the telescopic member 3 can be arranged on the rotating shaft 2 only corresponding to the convex portion 12 of the inner wall, or the telescopic member 3 can be arranged on the rotating shaft 2 corresponding to both the convex portion 12 and the concave portion 11 of the inner wall, so that the telescopic member 3 corresponds to both the convex portion 12 and the concave portion 11 of the inner wall.

[0081] After being arranged in this way, the telescopic member 3 can abut against the recessed portion 11 and / or the convex portion 12 of the inner wall when stationary, and can provide a reaction force to the rotating shaft 2 in a certain regularity even when rotating, and can also make the telescopic member 3 abut against the recessed portion 11 and / or the convex portion 12 of the inner wall in at least a certain state to balance and fix the rotating shaft 2.

[0082] A folding device 100 provided in an embodiment of the present application has a certain regularity in arrangement of the telescopic component on the rotating shaft 2 by arranging the concave portion 11 and / or convex portion 12 of the inner wall corresponding to the telescopic component 3 on the rotating shaft 2 when the telescopic component is stationary, and when the telescopic component 3 rotates to the corresponding concave portion 11 and / or convex portion 12, the elastic force formed by the telescopic component 3 corresponds to a minimum value and / or a maximum value, so that the telescopic component as a whole is in an extreme state, thereby achieving an optimal hovering balance state.

[0083] As an optional embodiment, please continue to refer to Figure 4 and Figure 5 The concave portions 11 are arranged in pairs, and the concave portions 11 arranged in pairs are symmetrically distributed with the rotation shaft 2 as the center. The convex portions 12 are arranged in pairs, and the convex portions 12 arranged in pairs are symmetrically distributed with the rotation shaft 2 as the center.

[0084] The present embodiment provides a symmetrical structure of a petal-shaped inner wall, so that the concave portions 11 are symmetrically distributed in pairs, and the convex portions 12 are symmetrically distributed in pairs, which further improves the overall regularity.

[0085] In this way, the telescopic parts 3 corresponding to the recessed parts 11 and / or the convex parts 12 arranged on the rotating shaft 2 are also symmetrically distributed in pairs, which further makes the distribution of the telescopic parts 3 regular and provides opposite and equal elastic forces to the rotating shaft 2, so that the rotating shaft 2 can obtain a more stable balance whether it is rotating or hovering.

[0086] The present application does not impose any special limitation on the number of the concave portions 11 and the convex portions 12 on the inner wall of the fixing member 1 , and the specific number thereof also determines the number of telescopic members 3 and the density of their arrangement, as long as a smooth transition of the inner wall and a spacing between corresponding telescopic members 3 can be ensured.

[0087] A folding device 100 provided in an embodiment of the present application adjusts the petal-shaped inner wall into a symmetrical structure so that the recessed portion 11 and the convex portion 12 are symmetrically distributed with the rotating shaft 2 as the center. The overall structure has regularity, which is more conducive to the layout of the telescopic part 3 on the rotating shaft 2. The corresponding setting also has regularity, which can better provide force to the telescopic part 3 and offset the balance, thereby further improving the stability of the rotating shaft 2 when it is suspended.

[0088] As an alternative embodiment, see Figures 2 to 5 The folding portion 10 also includes an adapter 4, which has a through hole 41 that penetrates along the axial direction X. The rotating shaft 2 is inserted into the through hole 41 and connected to the telescopic member 3 through the adapter 4. One end of the telescopic member 3 is connected to the rotating shaft 2 through the adapter 4 and the other end abuts against the inner wall of the fixed member 1. The rotating shaft 2 can drive the adapter 4 to rotate to drive the telescopic member 3 to rotate relative to the fixed member 1.

[0089] Optionally, an adapter 4 is arranged between the rotating shaft 2 and the telescopic member 3. In order to adapt to the structure of the rotating shaft 2, the adapter 4 can be arranged into a cylindrical structure. Since the adapter 4 is located between the rotating shaft 2 and the telescopic member 3, it is necessary to ensure that the radial Y dimension of the adapter 4 is smaller than the radial Y dimension of the fixing member 1, so that the adapter 4 can be located in the accommodating cavity 101 of the fixing member 1.

[0090] A cylindrical through hole 41 is formed on the adapter 4 along the axial direction X so that the shaft 2 can be inserted into the through hole 41. The axial length X of the adapter 4 is smaller than the length of the shaft 2, and at least both ends of the shaft 2 can be exposed for connecting the foldable component.

[0091] The rotating shaft 2 is inserted into the through hole 41 of the adapter 4, and the two are tightly connected, so that the rotation of the rotating shaft 2 can drive the adapter 4 to rotate together, and can also rotate clockwise or counterclockwise.

[0092] Since the rotating shaft 2 has been inserted into the adapter 4 and the adapter 4 can rotate with the rotating shaft 2, one end of the telescopic member 3 needs to be connected to the adapter 4 to form an indirect connection with the rotating shaft 2, and the other end thereof is in contact with the inner wall of the fixing member 1 as usual, and the telescopic member 3 is driven to rotate by the rotation of the adapter 4.

[0093] When rotated to a predetermined position, the reverse force generated by the telescopic member 3 first acts on the adapter 4, and the telescopic assembly as a whole forms an extrusion force on the adapter 4, so that the adapter 4 is suspended in a stationary manner in the accommodating cavity 101, thereby keeping the inserted shaft 2 also suspended in a stationary manner.

[0094] A folding device 100 provided in an embodiment of the present application forms an indirect connection between the rotating shaft 2 and the telescopic member 3 by arranging an adapter 4 in the folding portion 10 and sleeved on the rotating shaft 2. On the basis of realizing transmission, direct contact between the telescopic member 3 and the rotating shaft 2 is avoided, local isolation protection is formed for the rotating shaft 2, wear during rotation is reduced, and the service life of the structure is increased.

[0095] As an optional embodiment, please continue to refer to Figures 2 to 5 The folding portion 10 also includes a limit member 5, which is sleeved on the rotating shaft 2, one end of the limit member 5 is connected to the rotating shaft 2 and the other end abuts against the adapter 4, and the limit member 5 is configured to prevent the adapter 4 from moving along the axial direction X.

[0096] Optionally, the limiting member 5 may be a spring structure or a block structure, and it only needs to form an axial X-direction blocking effect on the adapter 4 .

[0097] Specifically, the limit member 5 can be sleeved on the exposed part of the rotating shaft 2, and then one end of the limit member 5 is fixed, and the other end thereof abuts against the adapter 4. When the rotating shaft 2 drives the adapter 4 to rotate, if the adapter 4 moves along the axial direction X, the set limit member 5 can support the adapter 4, thereby blocking the adapter 4 and preventing it from deviating.

[0098] If the limiting member 5 adopts a spring structure, it can form a certain buffer for the adapter 4 in the axial direction X, thereby avoiding damage caused by hard squeezing between structures.

[0099] Optionally, the folding portion 10 has two limit members 5, which are respectively arranged on both sides of the adapter 4 in the axial direction X, so that both ends of the adapter 4 can be blocked to prevent the adapter 4 from moving forward and backward on the rotating shaft 2.

[0100] A folding device 100 provided in an embodiment of the present application can fix the adapter 4 in the axial direction X by setting a limit member 5 in the folding portion 10, thereby preventing the adapter 4 from moving back and forth on the rotating shaft 2, ensuring that the telescopic member 3 on the adapter 4 is always in contact with the inner wall of the fixing member 1, so that the rotating shaft 2 is fixed and suspended, thereby improving the reliability of the suspension of the rotating shaft 2.

[0101] As an optional embodiment, please continue to refer to Figures 2 to 5 The folding portion 10 further includes a shielding member 6 , which is disposed between the limiting member 5 and the adapter 4 . The adapter 4 can rotate relative to the shielding member 6 . One end of the limiting member 5 is connected to the rotating shaft 2 and the other end abuts against the shielding member 6 .

[0102] Considering that the adapter 4 needs to rotate, and the limiter 5 is in direct contact with the adapter 4, a shielding member 6 may be provided between the two to avoid wear between them.

[0103] Optionally, the shielding member 6 is a plate-like structure and has a through hole. The shaft 2 passes through the through hole of the shielding member 6 and is then inserted into the adapter 4 . The shielding member 6 is sleeved on the shaft 2 and is stationary relative to the shaft 2 .

[0104] The limiting member 5 is abutted against the shielding member 6, which not only forms an indirect blockage for the adapter 4, but also avoids wear caused by direct contact with the adapter 4.

[0105] A folding device 100 provided in an embodiment of the present application can separate the limiting member 5 from the adapter 4 by setting a shielding member 6 in the folding portion 10, thereby avoiding direct contact between the two, reducing wear caused by rotation, improving the safety performance between rotating parts, and extending the service life of the structures. At the same time, the shielding member 6 can also form an axial X-blocking effect on the adapter 4, and has a certain limiting capability.

[0106] A display device provided in an embodiment of the present application includes a display panel and the folding device 100 as described above, wherein the folding device 100 is connected to the display panel so that the display panel is foldable.

[0107] It should be noted that the display device in this embodiment can be an electronic device such as a mobile phone or a tablet computer. As long as the device has a foldable display panel, it can be folded by the folding device 100 and can be freely hovered at any angle. This application does not specifically limit the specific structure and usage environment of the display device.

[0108] The embodiment of the present application provides a folding device 100 and a display device, in which the folding portion 10 can achieve the connection between the rotating shaft 2 and the fixing member 1 through a telescopic component arranged between the rotating shaft 2 and the fixing member 1, and can also use the reverse force provided by the fixing member 1 to the telescopic component to act on the rotating shaft 2, thereby squeezing the rotating shaft 2 from multiple angles to make it stop and fix it in a predetermined position. Since the rotating shaft 2 is connected to the part to be folded, while the rotating shaft 2 drives the part to be folded to rotate at any angle, it achieves fixed hovering of the part to be folded at a certain angle, thereby improving the user experience and meeting the user's demand for fixed hovering of the folding part.

[0109] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
