Detailed Implementation

[0026] The technical solutions provided in this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments described in this application without creative effort are within the protection scope of this application.

[0027] In this application, the terms "embodiment" or "implementation" mean that a specific feature, structure, or characteristic described in connection with an embodiment or implementation can be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described in this application can be combined with other embodiments.

[0028] The terms “first,” “second,” etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, rather than to describe a particular order; furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover non-exclusive inclusion.

[0029] Please refer toFigures 1 to 3 , Figure 1 This is a schematic diagram of the foldable electronic device 1000 provided in this application embodiment when it is in a flattened state. Figure 2 This is a schematic diagram of the foldable electronic device 1000 provided in this application when it is in a folded state. Figure 3 This is a schematic diagram of the foldable electronic device 1000 provided in this application when it is in a hovering state. The foldable electronic device 1000 provided in this application can be a foldable mobile phone, a foldable tablet, a foldable e-reader, etc. A foldable mobile phone is used as an example in this application embodiment. The foldable electronic device 1000 has a flattened state, a folded state, and one or more hovering states. During use, the foldable electronic device 1000 can switch between the flattened state, the folded state, and the hovering state.

[0030] The foldable electronic device 1000 includes a flexible display screen 200 and a foldable housing 100. It is understood that when the foldable electronic device 1000 is in a flattened state, the flexible display screen 200 and the foldable housing 100 are also in a flattened state; when the foldable electronic device 1000 is in a folded state, the flexible display screen 200 and the foldable housing 100 are also in a folded state; and when the foldable electronic device 1000 is in a hovering state, the flexible display screen 200 and the foldable housing 100 are also in a hovering state.

[0031] like Figure 4 As shown, Figure 4 for Figure 1 The diagram shows the structure of the foldable housing 100 in the foldable electronic device 1000. The foldable housing 100 includes a first housing 11, a second housing 12, and a pivot mechanism 10. The first housing 11 is located on one side of the pivot mechanism 10, and the second housing 12 is located on the other side of the pivot mechanism 10. In the embodiments of this application, the first housing 11 and the second housing 12 are located on opposite sides of the pivot mechanism 10. This application does not specifically limit the structure of the first housing 11 or the second housing 12. In one possible embodiment, the first housing 11 may include a rectangular frame, and the second housing 12 may include a rectangular frame. The first housing 11 and the second housing 12 can move towards each other to fold, or the first housing 11 and the second housing 12 can move away from each other to flatten. Specifically, Figure 4 Taking the foldable housing 100 shown as an example, during the process of switching the foldable housing 100 from the flattened state to the folded state, the first housing 11 gradually rotates in the clockwise direction and the second housing 12 gradually rotates in the counterclockwise direction; during the process of switching the foldable housing 100 from the folded state to the flattened state, the first housing 11 gradually rotates in the counterclockwise direction and the second housing 12 gradually rotates in the clockwise direction.

[0032] Understandably, when the foldable shell 100 is in a flattened state, the pivot mechanism 10 is also in a flattened state; when the foldable shell 100 is in a folded state, the pivot mechanism 10 is also in a folded state; when the foldable shell 100 is in a folded state, the pivot mechanism 10 is also in a folded state; and when the foldable shell 100 is in a hovered state, the pivot mechanism 10 is also in a hovered state. Specifically, the foldable shell 100 being in a flattened state can be understood as the angle between the first shell 11 and the second shell 12 being 180° or close to 180°. The foldable shell 100 being in a folded state can be understood as the angle between the first shell 11 and the second shell 12 being 0° or close to 0°. The foldable shell 100 being in a hovered state can be understood as the angle between the first shell 11 and the second shell 12 being any angle between 0° and 180°.

[0033] Please refer to Figure 4 and Figure 5 The flexible display screen 200 includes a first non-bending display area 21, a bending display area 22, and a second non-bending display area 23 arranged sequentially. The first non-bending display area 21 covers the first housing 11. The bending display area 22 covers the rotating shaft mechanism 10. The second non-bending display area 23 covers the second housing 12.

[0034] The flexible display screen 200 can be a flexible organic light-emitting diode (OLED) display screen. The first non-bending display area 21 can be fixedly connected to the first housing 11. The second non-bending display area 23 can be fixedly connected to the second housing 12. Optionally, the non-display side of the first non-bending display area 21 is bonded to the first housing 11, and the non-display side of the second non-bending display area 23 is bonded to the second housing 12. When the flexible display screen 200 switches between a flattened state, a folded state, and a hovering state, the first non-bending display area 21 and the second non-bending display area 23 do not bend. The bending display area 22 can be either not connected or partially connected to the pivot mechanism 10. The bending display area 22 flattens when the flexible display screen 200 is in the flattened state and bends when the flexible display screen 200 is in the folded state.

[0035] In one possible embodiment, such as Figure 6As shown, the flexible display screen 200 can be teardrop-shaped when folded. Specifically, the bent display area 22 may include a first sub-bent-bent display area 221, a second sub-bent-bent display area 222, and a third sub-bent-bent display area 223 arranged sequentially. The first sub-bent-bent display area 221 is adjacent to the first non-bent display area 21. The third sub-bent-bent display area 223 is adjacent to the second non-bent display area 23. It can be understood that the flexible display screen 200 includes a first non-bent display area 21, a first sub-bent-bent display area 221, a second sub-bent-bent display area 222, a third sub-bent-bent display area 223, and a second non-bent display area 23 arranged sequentially. When the flexible display screen 200 is in the folded state, the first non-bending display area 21 and the second non-bending display area 23 are opposite each other. The line length between the end of the first sub-bending display area 221 away from the second sub-bending display area 222 and the end of the third sub-bending display area 223 away from the second sub-bending display area 222 is L1, and the line length between the end of the first sub-bending display area 221 near the second sub-bending display area 222 and the end of the third sub-bending display area 223 near the second sub-bending display area 222 is L2, where L1 is less than L2. In this embodiment, the first sub-bending display area 221 and the third sub-bending display area 223 of the bending display area 22 can be connected to the rotating shaft mechanism 10 and bend under the action of the rotating shaft mechanism 10, respectively. The second sub-bending display area 222 of the bending display area 22 is not connected to the rotating shaft mechanism 10, so it can bend freely.

[0036] Please refer to Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of one side of the rotating shaft mechanism 10 provided in the embodiments of this application when it is in a flattened state. Figure 8 for Figure 7 The exploded view of the rotating shaft mechanism 10 is shown. The rotating shaft mechanism 10 includes a base 101, a first rotating shaft assembly 102, and a torque assembly 103.

[0037] The base 101 remains stationary when the rotating shaft mechanism 10 switches between the flattened state, the hovering state, and the folded state.

[0038] The first rotating shaft assembly 102 includes a first movable seat 121, a first connecting arm 122, and a first rotating arm 123. The first movable seat 121 is spaced apart from the base 101. When the rotating shaft mechanism 10 is in a flattened state, the first movable seat 121 is located on one side of the base 101. In this embodiment, the first movable seat 121 is spaced apart on the left side of the base 101 when the rotating shaft mechanism 10 is in a flattened state. Of course, in other embodiments, the first movable seat 121 may be spaced apart on the right side of the base 101 when the rotating shaft mechanism 10 is in a flattened state. The first movable seat 121 can be fixedly connected to the first housing 11. For example, the first movable seat 121 and the first housing 11 can be fixedly connected by means of bonding, welding, bolting, snap-fit ​​connection, etc. The first connecting arm 122 is located between the base 101 and the first movable seat 121. The first rotating arm 123 is located between the base 101 and the first movable seat 121. The first connecting arm 122 and the first rotating arm 123 are spaced apart.

[0039] The first link arm 122 is rotatably connected to the base 101 and slidably connected to the first movable seat 121. For example, the first link arm 122 and the base 101 are rotatably connected via a rotating shaft and a shaft hole. Optionally, the first link arm 122 has a shaft hole, and the base 101 has a rotating shaft; or, the first link arm 122 has a rotating shaft, and the base 101 has a shaft hole. The rotating shaft on the base 101 can be understood not only as the base 101 and the rotating shaft being integrally formed, but also as the base 101 and the rotating shaft being fixedly connected, meaning there is no relative movement between the base 101 and the rotating shaft. Similarly, the rotating shaft on the first link arm 122 can be understood not only as the first link arm 122 and the rotating shaft being integrally formed, but also as the first link arm 122 and the rotating shaft being fixedly connected, meaning there is no relative movement between the first link arm 122 and the rotating shaft. The first link arm 122 and the first movable seat 121 are slidably connected via a slider and a sliding groove. Optionally, the first linkage arm 122 is provided with a slider and the first movable seat 121 is provided with a groove; or, the first linkage arm 122 is provided with a groove and the first movable seat 121 is provided with a slider.

[0040] The first rotating arm 123 is rotatably connected to the base 101 and also rotatably connected to the first movable seat 121. For example, the first rotating arm 123 and the base 101 are rotatably connected via a circular arc groove and a circular arc block. Optionally, the first rotating arm 123 has a circular arc block, and the base 101 has a circular arc groove; or, the first rotating arm 123 has a circular arc groove, and the base 101 has a circular arc block. The first rotating arm 123 and the first movable seat 121 are rotatably connected via a rotating shaft and a shaft hole. Optionally, the first rotating arm 123 has a shaft hole, and the first movable seat 121 has a rotating shaft; or, the first rotating arm 123 has a rotating shaft, and the first movable seat 121 has a shaft hole. The first movable seat 121 having a rotating shaft can be understood not only as the first movable seat 121 and the rotating shaft being integrally formed, but also as the first movable seat 121 and the rotating shaft being fixedly connected, meaning there is no relative movement between the first movable seat 121 and the rotating shaft. The first rotating arm 123 is provided with a rotating shaft, which can be understood as either the first rotating arm 123 and the rotating shaft being integrally formed, or the first rotating arm 123 being fixedly connected to the rotating shaft, meaning that there is no relative movement between the first rotating arm 123 and the rotating shaft.

[0041] In this embodiment, the first connecting arm 122 is rotatably connected to the base 101 and slidably connected to the first movable seat 121. The first rotating arm 123 is rotatably connected to the base 101 and rotatably connected to the first movable seat 121, forming a crank-slider mechanism. This mechanism enables the flexible display screen 200 to be teardrop-shaped when folded, and also allows the length change of the rotating shaft mechanism 10 to adapt to the length change of the flexible display screen 200, thereby avoiding stretching or squeezing of the flexible display screen 200 during the bending process of the rotating shaft mechanism 10.

[0042] The torque assembly 103 includes an extruder 131, a connector 132, and a first elastic member 133. The extruder 131 is supported on the base 101. Specifically, the extruder 131 can be directly supported on the base 101 or indirectly supported on the base 101 through other components. When the extruder 131 is directly supported on the base 101, the extruder 131 is in contact with the base 101; when the extruder 131 is indirectly supported on the base 101 through other components, the extruder 131 may or may not be in contact with the base 101. The extruder 131 engages with the cam of the first connecting arm 122. In one possible embodiment, the extruder 131 has a first cam surface 1310, and the first connecting arm 122 has a second cam surface 1221. The first cam surface 1310 contacts the second cam surface 1221 to enable the extruder 131 to engage with the cam of the first connecting arm 122. The first cam surface 1310 may include a convex surface and a concave surface. The second cam surface 1221 may also include a convex surface and a concave surface. Since the extruder 131 is cam-engaged with the first connecting arm 122, the extruder 131 will slide relative to the base 101 during the rotation of the first connecting arm 122 relative to the base 101. In this embodiment, the extruder 131 slides relative to the base 101 along the axial direction of the rotating shaft mechanism 10. The axial direction of the rotating shaft mechanism 10 can be referred to in the attached diagram. Figure 7 The direction of the M line in the diagram. The axial direction of the rotating shaft mechanism 10 is also the direction of the axis of rotation of the first link arm 122 relative to the base 101.

[0043] The connector 132 is supported on the base 101 and rotatably connected to the base 101. In this embodiment, the connector 132 can be directly supported on the base 101. In other words, the connector 132 is in contact with the base 101. The connector 132 and the base 101 can be rotatably connected through the fit of a rotating shaft and a shaft hole. Optionally, the connector 132 has a shaft hole and the base 101 has a rotating shaft; or, the connector 132 has a rotating shaft and the base 101 has a shaft hole. One end of the connector 132 abuts against the side of the extruder 131 opposite to the first connecting rod arm 122. It can be understood that one end of the connector 132 contacts the side of the extruder 131 opposite to the first connecting rod arm 122. Since the connecting member 132 is rotatably connected to the base 101, the connecting member 132 can only rotate relative to the base 101 and cannot slide relative to it. However, the pressing member 131 slides relative to the base 101 under the action of the first connecting arm 122, and one end of the connecting member 132 abuts against the side of the pressing member 131 opposite to the first connecting arm 122. Therefore, during the sliding process of the pressing member 131 relative to the base 101 under the action of the first connecting arm 122, it drives the connecting member 132 to rotate relative to the base 101. In short, the pressing member 131 drives the connecting member 132 to rotate relative to the base 101 during the rotation of the first connecting arm 122 relative to the base 101. The connecting member 132 can be tilted relative to the side of the pressing member 131 opposite to the first connecting arm 122. This allows for better driving of the connecting member 132 to rotate relative to the base 101 via the pressing member 131.

[0044] The first elastic element 133 can be a spring, a bellows, etc. In the following embodiments, the first elastic element 133 is exemplified by a spring. The first elastic element 133 is located between one side of the connecting member 132 and the base 101. It is understood that one end of the first elastic element 133 abuts against one side of the connecting member 132, and the other end of the first elastic element 133 abuts against the side of the base 101 facing the connecting member 132. In one possible implementation, when the rotating shaft mechanism 10 is in a flattened or folded state, the first elastic element 133 can be located in a compressed state between one side of the connecting member 132 and the base 101. In another possible implementation, when the rotating shaft mechanism 10 is in a flattened or folded state, the first elastic element 133 can be located in its original length state between one side of the connecting member 132 and the base 101. Since the first elastic element 133 is located between the connecting element 132 and the base 101, the connecting element 132 exerts a force on the first elastic element 133 during its rotation relative to the base 101, causing the first elastic element 133 to deform. In this application, to increase the torque of the rotating shaft mechanism 10, the connecting element 132 exerts a compressive force on the first elastic element 133 during its rotation relative to the base 101, thereby compressing the first elastic element 133. In short, the first elastic element 133 is compressed by the compression of the connecting element 132 during its rotation relative to the base 101.

[0045] The rotating shaft mechanism 10 provided in this application includes a base 101, a first rotating shaft assembly 102, and a torque assembly 103. The first rotating shaft assembly 102 includes a first movable seat 121, a first connecting arm 122, and a first rotating arm 123. The torque assembly 103 includes a pressing member 131, a connecting member 132, and a first elastic member 133. Since the first connecting arm 122 is rotatably connected to the base 101, the pressing member 131 is cam-fitted with the first connecting arm 122, and the connecting member 132 is rotatably connected to the base 101, with one end of the connecting member 132 abutting against the pressing member 131 away from the first rotating arm 123. One side of the first linkage arm 122 is located on one side. Therefore, during the rotation of the first linkage arm 122 relative to the base 101, the pressing member 131 can drive the connecting member 132 to rotate relative to the base 101. The first elastic member 133 is located between one side of the connecting member 132 and the base 101. Therefore, during the rotation of the connecting member 132 relative to the base 101, the first elastic member 133 will be compressed by the pressing member 132. In this way, the elastic force of the first elastic member 133 can be converted into the torque of the rotating shaft mechanism 10, thereby increasing the torque of the rotating shaft mechanism 10 and improving the hovering effect. The foldable housing 100 and foldable electronic device 1000 provided in this application include the rotating shaft mechanism 10, so the torque is large and the hovering effect is good.

[0046] like Figure 9As shown, the torque assembly 103 also includes a second elastic element 134. The second elastic element 134 can be a spring, a bellows, etc. In the following embodiments, the second elastic element 134 is exemplified by a spring. The second elastic element 134 is located between the other side of the connector 132 and the base 101. It can be understood that one end of the second elastic element 134 abuts against the other side of the connector 132, and the other end of the second elastic element 134 abuts against the side of the base 101 facing the connector 132. In the embodiments of this application, the second elastic element 134 and the first elastic element 133 are respectively located on opposite sides of the connector 132. In one possible embodiment, when the shaft mechanism 10 is in a flattened or folded state, the second elastic element 134 can be located in a compressed state between the other side of the connector 132 and the base 101. In another possible embodiment, when the shaft mechanism 10 is in a flattened or folded state, the second elastic element 134 can be located in its original length state between the other side of the connector 132 and the base 101. Since the second elastic element 134 is located between the connecting member 132 and the base 101, the connecting member 132 exerts a force on the second elastic element 134 during its rotation relative to the base 101, causing the second elastic element 134 to deform. In this application, to increase the torque of the rotating shaft mechanism 10, the connecting member 132 exerts a compressive force on the second elastic element 134 during its rotation relative to the base 101, thereby compressing the second elastic element 134. In short, the second elastic element 134 is compressed by the compression of the connecting member 132 during its rotation relative to the base 101.

[0047] In this embodiment, the number of elastic elements in the torque assembly 103 is increased. The elastic force of the first elastic element 133 and the elastic force of the second elastic element 134 can both be converted into the torque of the rotating shaft mechanism 10, thus further increasing the torque of the rotating shaft mechanism 10. In addition, the first elastic element 133 and the second elastic element 134 are compressed by the pressure of the connecting member 132, thus reducing the number of connecting members in the torque assembly 103. While increasing the torque of the rotating shaft mechanism 10, the structure of the rotating shaft mechanism 10 can be simplified, and the structural compactness of the rotating shaft mechanism 10 can be improved.

[0048] like Figure 10As shown, the base 101 includes a connected support portion 110 and a limiting portion 112. In this application, the connection between the support portion 110 and the limiting portion 112 can indicate that the support portion 110 and the limiting portion 112 are integrally connected, or it can indicate that the support portion 110 and the limiting portion 112 are fixedly connected in a detachable or non-detachable manner. It is understood that when the rotating shaft mechanism 10 switches between the flattened state, the suspended state, and the folded state, there is no relative movement between the support portion 110 and the limiting portion 112. The support portion 110 is used to support the extrusion member 131 and the connecting member 132. It is understood that the extrusion member 131 and the connecting member 132 are supported on the support portion 110. An accommodating space 113 is formed between the support portion 110, the limiting portion 112, and the extrusion member 131. The connecting member 132 is located within the accommodating space 113. In the embodiment of this application, the limiting portion 112 and the extrusion member 131 are arranged opposite each other along the axial direction of the rotating shaft mechanism 10.

[0049] The connector 132 can be a connecting rod. The connector 132 includes a first abutment portion 1320, a rotating connecting portion 1321, and a second abutment portion 1322 connected in sequence. The first abutment portion 1320, the rotating connecting portion 1321, and the second abutment portion 1322 are connected in sequence, i.e., the first abutment portion 1320, the rotating connecting portion 1321, and the second abutment portion 1322 are arranged sequentially. The first abutment portion 1320 is connected to the rotating connecting portion 1321, and the rotating connecting portion 1321 is connected to the second abutment portion 1322. The first abutment portion 1320 and the rotating connecting portion 1321 can be integrally connected, or they can be fixedly connected in a detachable or non-detachable manner. The rotating connecting portion 1321 and the second abutment portion 1322 can be integrally connected, or they can be fixedly connected in a detachable or non-detachable manner. Understandably, when the connecting member 132 rotates relative to the base 101, the first abutting part 1320, the rotating connecting part 1321, and the second abutting part 1322 all rotate relative to the base 101.

[0050] The first abutting portion 1320 abuts against the side of the extruder 131 opposite to the first connecting arm 122. The second abutting portion 1322 abuts against the side of the limiting portion 112 facing the extruder 131. It is understood that one end of the connecting member 132 abuts against the extruder 131, and the other end of the connecting member 132 abuts against the limiting portion 112 of the base 101. By having the first abutting portion 1320 abut against the side of the extruder 131 opposite to the first connecting arm 122, and the second abutting portion 1322 abut against the side of the limiting portion 112 facing the extruder 131, the connecting member 132 can be confined between the extruder 131 and the limiting portion 112 of the base 101. This prevents the connecting member 132 from sliding relative to the base 101 under the action of the extruder 131, thereby improving the reliability of the connecting member 132 compressing the first elastic member 133 and the second elastic member 134.

[0051] The rotating connecting part 1321 is rotatably connected to the base 101. In one possible embodiment, the rotating connecting part 1321 has a shaft hole. The shaft hole can be a through hole or a blind hole. In this embodiment, the shaft hole is exemplified as a through hole. The bearing part 110 includes a connecting shaft. The connecting shaft can be cylindrical. The connecting member 132 and the base 101 are rotatably connected through the engagement of the shaft hole and the connecting shaft.

[0052] The connector 132 and the base 101 are rotatably connected through a shaft hole and a connecting shaft, which simplifies the assembly of the connector 132 and the base 101. Furthermore, the rotatable connection portion 1321 is located between the first abutment portion 1320 and the second abutment portion 1322. The connector 132 and the base 101 are rotatably connected through a shaft hole in the rotatable connection portion 1321 and a connecting shaft in the bearing portion 110. While achieving the rotatable connection between the connector 132 and the base 101, this further restricts the connector 132 from sliding relative to the base 101, thereby improving the reliability of the connector 132 pressing against the first elastic element 133 and the second elastic element 134 to compress them.

[0053] like Figure 11 As shown, the limiting part 112 has an arcuate groove 112a on the side opposite to the extruder 131. The first rotating arm 123 includes an arcuate block 123a. The first rotating arm 123 and the base 101 are rotatably connected through the engagement of the arcuate groove 112a and the arcuate block 123a.

[0054] By rotatably connecting the first rotating arm 123 to the limiting part 112 of the base 101, the structural compactness of the rotating shaft mechanism 10 can be improved, and the axial dimension of the rotating shaft mechanism 10 can be reduced. In addition, the limiting part 112 has an arc groove 112a on the side opposite to the extruder 131, and the first rotating arm 123 includes an arc block 123a. The first rotating arm 123 and the base 101 are rotatably connected through the cooperation of the arc groove 112a and the arc block 123a, which is beneficial to the axis design of the virtual rotating shaft of the first rotating arm 123 and can reduce the squeezing and pulling of the flexible display screen 200.

[0055] During the rotation of the first link arm 122 relative to the base 101 from a flattened state to a folded state, the compression of the first elastic element 133 gradually increases and then gradually decreases, as does the compression of the second elastic element 134. Understandably, during this rotation, the compressive force exerted by the first link arm 122 on the first elastic element 133 gradually increases and then gradually decreases, as does the compressive force exerted by the first link arm 122 on the second elastic element 134. The elastic coefficients of the first and second elastic elements 133 can be the same or different. In the same state, the compression of the first and second elastic elements 133 can be the same or different.

[0056] Because during the rotation of the first link arm 122 relative to the base 101 from a flattened state to a folded state, the compression of the first elastic element 133 gradually increases and then gradually decreases, and the compression of the second elastic element 134 also gradually increases and then gradually decreases, the squeezing force exerted by the extruder 161 on the first elastic element 133 and the second elastic element 134 in the pivot mechanism 10 of this application is relatively large, thereby generating a relatively large torque in the torque assembly 103, which can ensure the hovering design of the pivot mechanism 10. Of course, in other possible embodiments, the compression of the first elastic element 133 and the second elastic element 134 may also undergo other changes during the rotation of the first link arm 122 relative to the base 101 from a flattened state to a folded state.

[0057] In one possible implementation, the extruder 131 may include a plurality of first protrusions and a plurality of first recesses. The first protrusions and first recesses are disposed adjacent to each other. For example, the extruder 131 may include two first protrusions and two first recesses; or, the extruder 131 may include three first protrusions and three first recesses. The first linkage arm 122 may include a plurality of second protrusions and a plurality of second recesses. The second protrusions and second recesses are disposed adjacent to each other. For example, the first linkage arm 122 may include two second protrusions and two second recesses; or, the first linkage arm 122 may include three second protrusions and three second recesses. When the pivot mechanism 10 is in a flattened state, the first protrusions engage with the second recesses, and the first recesses engage with the second protrusions. When the pivot mechanism 10 is in a folded state, the first protrusions engage with the second recesses, and the first recesses engage with the second protrusions. When the pivot mechanism 10 is in a suspended state, the first protrusions engage with the second protrusions, and the first recesses engage with the second recesses. In this embodiment, during the process of the first link arm 122 rotating from a flat state to a folded state relative to the base 101, the pressing force of the extruder 161 on the first elastic member 133 and the second elastic member 134 gradually increases and then gradually decreases, thereby making the compression amount of the first elastic member 133 gradually increase and then gradually decrease, and the compression amount of the second elastic member 134 gradually increase and then gradually decrease.

[0058] Please refer to Figure 12 and Figure 13 , Figure 12 This is a schematic diagram of the rotating shaft mechanism 10 provided in the embodiments of this application when it is in a flattened state. Figure 13 for Figure 12 An exploded view of the rotating shaft mechanism 10 shown. The rotating shaft mechanism 10 also includes a second rotating shaft assembly 104.

[0059] The second rotating shaft assembly 104 includes a second movable seat 141, a second connecting arm 142, and a second rotating arm 143. The second movable seat 141 is spaced apart from the base 101. When the rotating shaft mechanism 10 is in a flattened state, the second movable seat 141 is located on one side of the base 101. In this embodiment, the second movable seat 141 is spaced apart on the right side of the base 101 when the rotating shaft mechanism 10 is in a flattened state. Of course, in other embodiments, the second movable seat 141 may be spaced apart on the left side of the base 101 when the rotating shaft mechanism 10 is in a flattened state. The second movable seat 141 can be fixedly connected to the second housing 12. For example, the second movable seat 141 and the second housing 12 can be fixedly connected by means of bonding, welding, bolting, snap-fit ​​connection, etc. The second connecting arm 142 is located between the base 101 and the second movable seat 141. The second rotating arm 143 is located between the base 101 and the second movable seat 141. The second link arm 142 and the second rotating arm 143 are spaced apart.

[0060] The second linkage arm 142 is rotatably connected to the base 101 and slidably connected to the second movable seat 141. For example, the second linkage arm 142 and the base 101 are rotatably connected via a rotating shaft and a shaft hole. Optionally, the second linkage arm 142 has a shaft hole, and the base 101 has a rotating shaft; or, the second linkage arm 142 has a rotating shaft, and the base 101 has a shaft hole. The rotating shaft on the base 101 can be understood as either the base 101 and the rotating shaft being integrally formed, or as the base 101 and the rotating shaft being fixedly connected, meaning there is no relative movement between the base 101 and the rotating shaft. Similarly, the rotating shaft on the second linkage arm 142 can be understood as either the second linkage arm 142 and the rotating shaft being integrally formed, or as the second linkage arm 142 and the rotating shaft being fixedly connected, meaning there is no relative movement between the second linkage arm 142 and the rotating shaft. The second linkage arm 142 and the second movable seat 141 are slidably connected via a slider and a sliding groove. Optionally, the second linkage arm 142 is provided with a slider and the second movable seat 141 is provided with a groove; or, the second linkage arm 142 is provided with a groove and the second movable seat 141 is provided with a slider.

[0061] The second rotating arm 143 is rotatably connected to the base 101 and also rotatably connected to the second movable seat 141. For example, the second rotating arm 143 and the base 101 are rotatably connected via a circular arc groove and a circular arc block. Optionally, the second rotating arm 143 has a circular arc block, and the base 101 has a circular arc groove; or, the second rotating arm 143 has a circular arc groove, and the base 101 has a circular arc block. The second rotating arm 143 and the second movable seat 141 are rotatably connected via a rotating shaft and a shaft hole. Optionally, the second rotating arm 143 has a shaft hole, and the second movable seat 141 has a rotating shaft; or, the second rotating arm 143 has a rotating shaft, and the second movable seat 141 has a shaft hole. The rotating shaft in the second movable seat 141 can be understood not only as the second movable seat 141 and the rotating shaft being integrally formed, but also as the second movable seat 141 and the rotating shaft being fixedly connected, meaning there is no relative movement between the second movable seat 141 and the rotating shaft. The second rotating arm 143 is provided with a rotating shaft. This can be understood as either the second rotating arm 143 and the rotating shaft being integrally formed, or it can be understood as the second rotating arm 143 being fixedly connected to the rotating shaft, meaning that there is no relative movement between the second rotating arm 143 and the rotating shaft.

[0062] In this embodiment, the second linkage arm 142 is rotatably connected to the base 101 and slidably connected to the second movable seat 141. The second rotating arm 143 is rotatably connected to the base 101 and rotatably connected to the second movable seat 141, forming a crank-slider mechanism. This mechanism enables the flexible display screen 200 to be teardrop-shaped when folded, and also allows the length change of the rotating shaft mechanism 10 to adapt to the length change of the flexible display screen 200, thereby avoiding stretching or squeezing of the flexible display screen 200 during the bending process of the rotating shaft mechanism 10.

[0063] The rotating shaft mechanism 10 also includes a synchronizing element 105 disposed between the first connecting arm 122 and the second connecting arm 142. The synchronizing element 105 is used to drive the first connecting arm 122 and the second connecting arm 142 to rotate synchronously and in opposite directions relative to the base 101. In one possible embodiment, the synchronizing element 105 includes a first helical surface 151, a second helical surface 152, a third helical surface 153, and a fourth helical surface 154. The first connecting arm 122 includes a first sub-connecting rod portion 1222, a second sub-connecting rod portion 1223, and a third sub-connecting rod portion 1224 connected to the first sub-connecting rod portion 1222 and the second sub-connecting rod portion 1223. The first sub-connecting rod portion 1222 and the second sub-connecting rod portion 1223 are both rotatably connected to the base 101, and the first sub-connecting rod portion 1222 and the second sub-connecting rod portion 1223 are spaced apart. The third sub-connecting rod portion 1224 is slidably connected to the first movable seat 121. The first helical surface 151 and the second helical surface 152 are arranged opposite to each other and respectively contact and engage with the first sub-connecting rod portion 1222 and the second sub-connecting rod portion 1223. The second connecting arm 142 includes a fourth sub-connecting rod portion 1422, a fifth sub-connecting rod portion 1423, and a sixth sub-connecting rod portion 1424 connected to the fourth sub-connecting rod portion 1422 and the fifth sub-connecting rod portion 1423. The fourth sub-connecting rod portion 1422 and the fifth sub-connecting rod portion 1423 are both rotatably connected to the base 101, and the fourth sub-connecting rod portion 1422 and the fifth sub-connecting rod portion 1423 are spaced apart. The sixth sub-connecting rod portion 1424 is slidably connected to the second movable seat 141. The third helical surface 153 and the fourth helical surface 154 are arranged opposite to each other and respectively contact and engage with the fourth sub-connecting rod portion 1422 and the fifth sub-connecting rod portion 1423.

[0064] Understandably, in this embodiment, when the first link arm 122 rotates relative to the base 101, the synchronizing member 105 can drive the second link arm 142 to rotate synchronously and in the opposite direction relative to the base 101. When the second link arm 142 rotates relative to the base 101, the synchronizing member 105 can drive the first link arm 122 to rotate synchronously and in the opposite direction relative to the base 101. The orientation of the first helical surface 151 is opposite to that of the second helical surface 152. The orientations of the third helical surface 153 and the fourth helical surface 154 are opposite.

[0065] The synchronization element 105 enables the synchronous rotation of the first rotating shaft assembly 102 and the second rotating shaft assembly 104 relative to the base 101. The synchronization element 105 includes a first helical surface 151, a second helical surface 152, a third helical surface 153, and a fourth helical surface 154. The first helical surface 151 and the second helical surface 152 are positioned opposite to each other and respectively contact and engage with the first connecting arm 122. The third helical surface 153 and the fourth helical surface 154 are positioned opposite to each other and respectively contact and engage with the second connecting arm 142. This reduces the structural design complexity of the synchronization element 105, decreases its size, and makes the rotating shaft mechanism 10 more compact, thus facilitating the lightweight design of the foldable electronic device 1000.

[0066] Furthermore, the first rotating shaft assembly 102 also includes a first rotating shaft 124, through which the first connecting arm 122 is rotatably connected to the base 101. Specifically, the first sub-connecting rod portion 1222 and the second sub-connecting rod portion 1223 can be sleeved on the first rotating shaft 124, and the first rotating shaft 124 and the base 101 can be relatively fixed. The second rotating shaft assembly 104 also includes a second rotating shaft 144, through which the second connecting arm 142 is rotatably connected to the base 101. Specifically, the fourth sub-connecting rod portion 1422 and the fifth sub-connecting rod portion 1423 can be sleeved on the second rotating shaft 144, and the second rotating shaft 144 and the base 101 can be relatively fixed.

[0067] The extrusion member 131 includes a first extrusion portion 1311 and a second extrusion portion 1312 connected together. The first extrusion portion 1311 is sleeved on the first rotating shaft 124 and engages with the cam of the first connecting arm 122. The second extrusion portion 1312 is sleeved on the second rotating shaft 144 and engages with the cam of the second connecting arm 142. Specifically, the first extrusion portion 1311 has a first cam surface 1310, which contacts the second cam surface 1221 of the first connecting arm 122, so that the first extrusion portion 1311 engages with the cam of the first connecting arm 122. The second extrusion portion 1312 has a third cam surface, and the second connecting arm 142 has a fourth cam surface, which contacts the fourth cam surface, so that the second extrusion portion 1312 engages with the cam of the second connecting arm 142.

[0068] Since the extruder 131 includes a first extrusion part 1311 and a second extrusion part 1312 connected together, the first extrusion part 1311 is sleeved on the first rotating shaft 124 and engages with the cam of the first connecting arm 122, and the second extrusion part 1312 is sleeved on the second rotating shaft 144 and engages with the cam of the second connecting arm 142, during the synchronous rotation of the first connecting arm 122 and the second connecting arm 142 relative to the base 101, the extruder 131 can simultaneously slide relative to the base 101 under the drive of the first connecting arm 122 and the second connecting arm 142, thereby improving the reliability of the extruder 131 driving the connecting member 132 to rotate relative to the base 101. In addition, the first rotating shaft 124 and the second rotating shaft 144 can play a guiding role when the extruder 131 slides relative to the base 101, thereby further improving the reliability of the extruder 131 driving the connecting member 132 to rotate relative to the base 101.

[0069] The torque assembly 103 also includes a third elastic element 135 and a fourth elastic element 136. The third elastic element 135 can be a spring, a bellows, etc. The fourth elastic element 136 can be a spring, a bellows, etc. In the following embodiments, the third elastic element 135 and the fourth elastic element 136 are taken as springs. The third elastic element 135 is sleeved on the first rotating shaft 124 and abuts against the side of the first pressing part 1311 away from the first connecting arm 122 and between it and the base 101. The fourth elastic element 136 is sleeved on the second rotating shaft 144 and abuts against the side of the second pressing part 1312 away from the second connecting arm 142 and between it and the base 101. It can be understood that one end of the third elastic element 135 abuts against the first pressing part 1311, and the other end of the third elastic element 135 abuts against the side of the base 101 facing the first pressing part 1311. One end of the fourth elastic member 136 abuts against the second pressing portion 1312, and the other end of the fourth elastic member 136 abuts against the side of the base 101 facing the second pressing portion 1312. In one possible embodiment, the other end of the third elastic member 135 may abut against the side of the limiting portion 112 of the base 101 away from the first rotating arm 123, and the other end of the fourth elastic member 136 may abut against the side of the limiting portion 112 of the base 101 away from the second rotating arm 143.

[0070] During the rotation of the first link arm 122 and the second link arm 142 relative to the base 101, the pressing member 131 presses the third elastic member 135 and the fourth elastic member 136, causing them to compress. In one possible embodiment, when the shaft mechanism 10 is in a flattened or folded state, the third elastic member 135 can be in a compressed state between one side of the first link arm 122 and the base 101, and the fourth elastic member 136 can be in a compressed state between one side of the second link arm 142 and the base 101, thus providing a certain preload to ensure tight contact between the mating surfaces in the shaft mechanism 10. Of course, in other possible embodiments, when the shaft mechanism 10 is in a flattened or folded state, the third elastic member 135 can be in its original length between one side of the first link arm 122 and the base 101, and the fourth elastic member 136 can be in its original length between one side of the second link arm 142 and the base 101.

[0071] During the rotation of the first link arm 122 and the second link arm 142 relative to the base 101 from a flattened state to a folded state, the compression of the third elastic element 135 gradually increases and then gradually decreases, while the compression of the fourth elastic element 136 can also gradually increase and then gradually decrease. This allows for greater torque when the rotating shaft mechanism 10 is in a hovering state, improving its hovering effect.

[0072] The features mentioned above in the specification, claims, and drawings can be combined in any way as long as they are meaningful within the scope of this application. The advantages and features described for the rotating shaft mechanism are applied accordingly to electronic devices.

[0073] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application, and such improvements and refinements are also considered to be within the protection scope of this application.
