[0024] Combine the following Figures 1 to 7 A folding mechanism and an electronic device according to embodiments of the present application are described.

[0025] like Figure 1As shown, the folding mechanism according to some embodiments of the present application includes: a first folding part 1, including a first rotating shaft 10 and a first connecting wall 12 connected to each other; a second folding part 2, including a second rotating shaft 20 and a second connecting wall 22 connected to each other, the first folding part 1 and the second folding part 2 can rotate relative to each other so that the first connecting wall 12 is in a hovering state or a folded state relative to the second connecting wall 22, and at least one of the first connecting wall 12 and the second connecting wall 22 is provided with a first convex surface 120; a hovering part 3, connected to at least one of the first rotating shaft 10 and the second rotating shaft 20, and the hovering part 3 is provided with a second convex surface 32, wherein, in the hovering state, the first convex surface 120 is arranged relative to the second convex surface 32.

[0026] The folding mechanism according to the embodiment of the present application includes a first folding part 1, a second folding part 2 and a hovering part 3, the first folding part 1 includes a first rotating shaft 10 and a first connecting wall 12, the second folding part 2 includes a second rotating shaft 20 and a second connecting wall 22, the hovering part 3 is connected to at least one of the first rotating shaft 10 and the second rotating shaft 20, the first folding part 1 and the second folding part 2 can rotate relative to each other, so that the first connecting wall 12 can be in a hovering state or a moving state relative to the second connecting wall 22. Among them, a first convex surface 120 is provided on at least one of the first connecting wall 12 and the second connecting wall 22, and a second convex surface 32 is provided on the hovering part 3. In this way, during the relative rotation of the first folding part 1 and the second folding part 2, when the first convex surface 120 and the second convex surface 32 are arranged relative to each other, the first connecting wall 12 is in a hovering state relative to the second connecting wall 22, thereby improving the playability of the electronic device for users, expanding the use scenarios of the electronic device, and improving the user experience. At the same time, the folding mechanism proposed in the present application saves costs and space occupation of the entire machine compared to the hovering mechanism composed of cams and springs in the related art. At the same time, the matching parts of the first convex surface 120 and the second convex surface 32 can be flexibly adjusted.

[0027] like Figure 2 , Figure 3 and Figure 7 As shown, according to some embodiments of the present application, a first connecting portion 102 is provided on at least one of the first rotating shaft 10 and the second rotating shaft 20, a second connecting portion 30 is provided on the suspension portion 3, and the first connecting portion 102 and the second connecting portion 30 are threadedly connected.

[0028] In this embodiment, the first connecting part 102 and the second connecting part 30 are threadedly connected, so that when the first folding part 1 and the second folding part 2 rotate, the first connecting part 102 and the second connecting part 30 rotate relative to each other, so that the hovering part 3 moves along the axial direction of the rotating shaft, thereby realizing the hovering function of the folding mechanism.

[0029] In a specific application, an external thread is provided on the first connecting part 102, and an internal thread is provided on the second connecting part 30. The internal thread and the external thread are threadedly connected. When the first folding part 1 and the second folding part 2 rotate, the second connecting part 30 with the internal thread moves along the axial direction of the first rotating shaft 10, thereby driving the suspension part 3 as a whole to move along the axial direction of the first rotating shaft 10.

[0030] Specifically, the first convex surface 120 and the second convex surface 32 are elastic structures, or the first connecting wall 12 and the second connecting wall 22 include an elastic wall 122, and the first convex surface 120 is arranged on the elastic wall 122. The rotation of the first connecting wall 12 drives the first rotating shaft 10 to rotate. When the first rotating shaft 10 rotates, with the cooperation of the first connecting part 102 and the second connecting part 30, the second connecting part 30 drives the hovering part 3 to move along the axial direction of the first rotating shaft 10, and then the hovering part 3 drives the second convex surface 32 to move along the axial direction of the first rotating shaft 10, so that the second convex surface 32 can contact the first convex surface 120. When the top of the second convex surface 32 is opposite to the top of the first convex surface 120, the elastic wall 122 is deformed, thereby realizing soft extrusion of the first convex surface 120 and the second convex surface 32. The first convex surface 120 cooperates with the second convex surface 32 to generate a resistance torque. When the generated resistance torque is equal to the rebound force of the folding mechanism, the hovering function is realized.

[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, according to some embodiments of the present application, the first rotating shaft 10 and the second rotating shaft 20 are arranged in parallel, and a rotating member 104 is provided on the first rotating shaft 10 and the second rotating shaft 20 respectively, and the first rotating shaft 10 and the second rotating shaft 20 rotate synchronously through the rotating member 104.

[0032] In this embodiment, the first rotating shaft 10 and the second rotating shaft 20 are arranged in parallel and rotate synchronously through the rotating member 104. During the folding or unfolding process of the folding mechanism, the first rotating shaft 10 and the second rotating shaft 20 rotate synchronously, ensuring the reliability of the folding and unfolding of the folding mechanism.

[0033] In a specific application, the hovering portion 3 is respectively connected to the first rotating shaft 10 and the second rotating shaft 20. Further, the first rotating shaft 10 and the second rotating shaft 20 are both provided with a first connecting portion 102, and the hovering portion 3 is provided with two second connecting portions 30, which are respectively connected to the first connecting portion 102 on the first rotating shaft 10 and the second connecting portion 30 on the second rotating shaft 20, thereby improving the stability of the movement of the hovering portion 3.

[0034] In another specific application, a first connecting portion 102 is disposed on the first rotating shaft 10 , and a second connecting portion 30 is disposed on the hovering portion 3 . The first connecting portion 102 and the second connecting portion 30 are threadedly connected to achieve axial movement of the hovering portion 3 .

[0035] Specifically, the first shaft 10 and the second shaft 20 have the same length. The rotating member 104 on the first shaft 10 and the rotating member 104 on the second shaft 20 are arranged opposite to each other and can be directly connected or connected through other components to achieve synchronous rotation of the first shaft 10 and the second shaft 20.

[0036] like Figure 2 As shown, according to some embodiments of the present application, the suspension portion 3 includes a first suspension portion 34, a second suspension portion 36 and a connecting rod 38, the first suspension portion 34 and the second suspension portion 36 are arranged at both ends of the connecting rod 38, the first suspension portion 34 is sleeved on the first rotating shaft 10, the second suspension portion 36 is sleeved on the second rotating shaft 20, at least one of the first suspension portion 34 and the second suspension portion 36 is provided with a second connecting portion 30, and the first suspension portion 34 and the second suspension portion 36 are respectively provided with a second convex surface 32.

[0037] In this embodiment, the suspension part 3 includes a first suspension part 34, a second suspension part 36 and a connecting rod 38 disposed between the first suspension part 34 and the second suspension part 36. The first suspension part 34 is connected to the first rotating shaft 10, and the second suspension part 36 is connected to the second rotating shaft 20. In this way, when the first rotating shaft 10 and the second rotating shaft 20 rotate synchronously, the first suspension part 34 and the second suspension part 36 can move synchronously through the connecting rod 38, so that the folding mechanism can be reliably folded, suspended or unfolded. Among them, at least one of the first suspension part 34 and the second suspension part 36 is provided with a second connecting part 30, and the axial movement of the first suspension part 34 and the second suspension part 36 is realized by the cooperation of the first connecting part 102 and the second connecting part 30, so that the second convex surface 32 cooperates with the first convex surface 120, thereby making the folding mechanism have a suspended state.

[0038] In a specific application, a first connecting portion 102 is provided on the first rotating shaft 10, and a second connecting portion 30 is provided in the mounting hole of the first suspended portion 34. The first suspended portion 34 is sleeved on the first rotating shaft 10, so that the first connecting portion 102 is threadedly connected to the second connecting portion 30. When the first rotating shaft 10 rotates, the second rotating shaft 20 rotates synchronously with the first rotating shaft 10 through the cooperation of the rotating member 104. The first suspended portion 34 rotates along the axial direction of the first rotating shaft 10 through the cooperation of the first connecting portion 102 and the second connecting portion 30. The second suspended portion 36 moves synchronously with the first suspended portion 34 through the connecting rod 38, and then the second convex surface 32 on the first suspended portion 34 cooperates with the first convex surface 120 on the first connecting wall 12, and the second convex surface 32 on the second suspended portion 36 cooperates with the first convex surface 120 on the second connecting wall 22, so that the first folding portion 1 and the second folding portion 2 can move simultaneously to achieve a hovering function.

[0039] Furthermore, the second convex surface 32 on the first suspension portion 34 extends in an arc shape along the circumference of the first rotating shaft 10 on the first suspension portion 34 , and the second convex surface 32 on the second suspension portion 36 extends in an arc shape along the circumference of the second rotating shaft 20 on the second suspension portion 36 .

[0040] like Figures 3 to 5 As shown, according to some embodiments of the present application, the first connecting wall 12 and the second connecting wall 22 respectively include an elastic wall 122, and the first convex surface 120 is arranged on the elastic wall 122, wherein, in the hovering state, the elastic wall 122 is in a deformed state, and the top of the first convex surface 120 is arranged opposite to the top of the second convex surface 32.

[0041] In this embodiment, the first connecting wall 12 and the second connecting wall 22 respectively include an elastic wall 122, and the first convex surface 120 is arranged on the elastic wall 122. In this way, when the first rotating shaft 10 rotates, with the cooperation of the first connecting part 102 and the second connecting part 30, the second connecting part 30 drives the hovering part 3 to move along the axial direction of the first rotating shaft 10, and then the hovering part 3 drives the second convex surface 32 to move along the axial direction of the first rotating shaft 10, so that the second convex surface 32 can contact the first convex surface 120. When the top of the second convex surface 32 is arranged relative to the top of the first convex surface 120, the elastic wall 122 is deformed, thereby realizing soft extrusion of the first convex surface 120 and the second convex surface 32. The first convex surface 120 cooperates with the second convex surface 32 to generate a resistance torque. When the generated resistance torque is equal to the rebound force of the folding mechanism, the hovering function is realized.

[0042] In specific applications, such as Figure 1 and Figure 6As shown, the first connecting wall 12 and the second connecting wall 22 also include a swing arm 5, which is fixedly connected to the corresponding first rotating shaft 10 or second rotating shaft 20. The movement of the swing arm 5 drives the first rotating shaft 10 or the second rotating shaft 20 to move, thereby driving the hovering part 3 to move.

[0043] like Figure 2 As shown, according to some embodiments of the present application, when one of the first rotating shaft 10 and the second rotating shaft 20 is provided with a first connecting portion 102, the other of the first rotating shaft 10 and the second rotating shaft 20 includes a flattened shaft 200; one of the first suspended portion 34 and the second suspended portion 36 is provided with a second connecting portion 30, and the other is provided with a through hole 39; the flattened shaft 200 is provided in the through hole 39 and can rotate in the through hole 39, and the first connecting portion 102 is threadedly connected to the second connecting portion 30.

[0044] In this embodiment, when the first connecting portion 102 is provided on one of the first rotating shaft 10 and the second rotating shaft 20, the other of the first rotating shaft 10 and the second rotating shaft 20 includes a flattened shaft 200, and the second connecting portion 30 is provided on one of the first hanging portion 34 and the second hanging portion 36, and the other is provided with a through hole 39. In this way, the first connecting portion 102 and the second connecting portion 30 are threadedly connected, and the flattened shaft 200 is arranged in the through hole 39. When the first rotating shaft 10 and the second rotating shaft 20 rotate synchronously, one of the first hanging portion 34 and the second hanging portion 36 moves axially along the first rotating shaft 10 or the second rotating shaft 20 through the threaded connection between the first connecting portion 102 and the second connecting portion 30, and drives the other to move axially along the first rotating shaft 10 through the connecting rod 38, so that the first hanging portion 34 and the second hanging portion 36 move synchronously, thereby reducing the friction between the hanging portion 3 and the first rotating shaft 10 or the second rotating shaft 20.

[0045] It is understandable that the flattened shaft 200 is a section provided on the circular shaft, so that a flat plane is formed on the shaft, thereby reducing the contact area between the shaft and the through hole 39 to reduce the friction between the suspension portion 3 and the first rotating shaft 10 or the second rotating shaft 20 .

[0046] Specifically, the flattening shaft 200 includes two oppositely disposed cut surfaces, which reduce the friction between the flattening shaft 200 and the through hole 39 .

[0047] In addition, a mounting hole is provided in the one of the first suspension portion 34 and the second suspension portion 36 where the second connection portion 30 is provided, and the second connection portion 30 is provided on the inner wall surface of the mounting hole.

[0048] like Figure 1As shown, according to some embodiments of the present application, the folding mechanism also includes: a synchronization member 4, which is located between the rotating member 104 on the first rotating shaft 10 and the rotating member 104 on the second rotating shaft 20, and is connected to the rotating member 104 on the first rotating shaft 10 and the rotating member 104 on the second rotating shaft 20.

[0049] In this embodiment, the folding mechanism also includes a synchronizer 4, which is disposed between a rotating member 104 of the first rotating shaft 10 and a rotating member 104 of the second rotating shaft 20, and is connected to the two rotating members 104. In this way, when one of the first rotating shaft 10 and the second rotating shaft 20 rotates, the other can be driven to rotate through the synchronizer 4, so that the first folding portion 1 and the second folding portion 2 move synchronously, thereby realizing the folding, hovering, and unfolding functions of the folding mechanism.

[0050] like Figure 1 As shown, according to some embodiments of the present application, the synchronizer 4 includes a first gear, the rotating member 104 includes a second gear, and the first gear is meshingly connected with the second gear.

[0051] In this embodiment, the synchronizer 4 includes a first gear, and the rotating member 104 includes a second gear. The meshing transmission between the first gear and the second gear improves the reliability and stability of the synchronous movement of the first rotating shaft 10 and the second rotating shaft 20.

[0052] According to some embodiments of the present application, Figure 3 As shown, the folding mechanism also includes a folded state and an unfolded state. In the folded state, along the axial direction of the first rotating shaft 10, the first convex surface 120 is located below the second convex surface 32; Figure 5 As shown, in the unfolded state, along the axial direction of the first rotating shaft 10 , the first convex surface 120 is located above the second convex surface 32 .

[0053] In this embodiment, along the axial direction of the first rotating shaft 10, in the folded state, the first convex surface 120 is located below the second convex surface 32, and in the unfolded state, the first convex surface 120 is located above the second convex surface 32. In this way, when the folding mechanism switches from the unfolded state to the folded state, or from the folded state to the unfolded state, the first convex surface 120 and the second convex surface 32 will produce relative movement along the axial direction of the first rotating shaft 10, so that the first convex surface 120 contacts the second convex surface 32, and when the top of the first convex surface 120 is engaged with the top of the second convex surface 32, a hovering function is achieved.

[0054] In specific applications, the hover function mainly refers to the user controlling the screen opening and closing angles to achieve hovering at different angles. This solution implements the hover function in the following ways:

[0055] 1) The user unfolds the folding mechanism to rotate the swing arm 5;

[0056] 2) A second gear and a thread are arranged on the first rotating shaft 10 to form a gear screw. The swing arm 5 drives the gear screw to rotate, and the first gear rotates synchronously to make the angles on both sides consistent, such as Figure 1 As shown;

[0057] 3) The gear screw and the suspension part 3 are matched with each other through a threaded screw. As the screw rotates, the suspension part 3 is driven to move downward. Figure 2 and Figure 7 As shown;

[0058] 4) The suspension portion 3 moves downward, and the positions of the first convex surface 120 and the second convex surface 32 are changed from Figure 3 The position in the folded state becomes Figure 4 In the hovering state, the elastic wall 122 is deformed so that the second convex surface 32 of the hovering portion 3 and the first convex surface 120 of the elastic wall 122 are softly squeezed, and the two convex surfaces mesh with each other to generate a resistance torque. When the generated resistance torque is equal to the rebound force of the folding mechanism, the hovering function is achieved.

[0059] 5) When the folding mechanism is fully unfolded, the first convex surface 120 and the second convex surface 32 are not engaged, and the state is as follows: Figure 5 ;

[0060] 6) When the folding mechanism changes from the unfolded state to the folded state, the movement mode of the hovering portion 3 is opposite to the above description. During the closing process of the folding mechanism, the swing arm 5 is driven to rotate, thereby driving the gear screw to rotate, driving the hovering portion 3 to move upward, and the first convex surface 120 and the second convex surface 32 are engaged to achieve hovering. Finally, the folding mechanism is closed, and the first convex surface 120 and the second convex surface 32 are not engaged.

[0061] It should be noted that Figure 3 and Figure 4 In the schematic diagram shown, only the positions of the first convex surface 120 and the second convex surface 32 are shown, and the positions of the first folding portion 1 and the second folding portion 2 are not shown.

[0062] The folding mechanism proposed in the present application utilizes a threaded screw drive to drive the second convex surface 32 of the hovering portion 3 and the first convex surface 120 on the elastic wall 122 to achieve hovering through mutual engagement, which brings the following beneficial effects: the entire cam and spring mechanism in the related technology is eliminated, saving costs and overall machine space; the hovering portion 3 and the elastic wall 122 can be flexibly adjusted in the design space.

[0063] According to some embodiments of the present application, an electronic device is provided, comprising: a folding mechanism as described in any one of the first aspects.

[0064] In the embodiments proposed in the present application, since the folding mechanism proposed in any of the above embodiments is included, all the beneficial effects of the folding mechanism are possessed.

[0065] According to some embodiments of the present application, the electronic device further includes: a flexible screen, which covers the first folding portion 1 and the second folding portion 2.

[0066] In this embodiment, the electronic device also includes a flexible screen, which covers the first folding part 1 and the second folding part 2. The flexible screen is folded, hovered or unfolded through the relative movement of the first folding part 1 and the second folding part 2.

[0067] Among them, when the first rotating shaft 10 or the second rotating shaft 20 rotates, with the cooperation of the first connecting part 102 and the second connecting part 30, the second connecting part 30 drives the hovering part 3 to move along the axial direction of the first rotating shaft 10, and then the hovering part 3 drives the second convex surface 32 to move along the axial direction of the first rotating shaft 10, so that the second convex surface 32 can contact the first convex surface 120. When the top of the second convex surface 32 engages with the top of the first convex surface 120, the elastic wall 122 is deformed, thereby realizing soft extrusion of the first convex surface 120 and the second convex surface 32. The first convex surface 120 cooperates with the second convex surface 32 to generate a resistance torque. When the generated resistance torque is equal to the rebound force of the flexible screen, the hovering function is realized.

[0068] Specifically, the electronic device may be a smart phone, a tablet computer, an e-reader, a wearable device, etc., which are not listed here one by one.
