[0046] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present application. On the contrary, they are merely examples of the devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the Figure 1 orientation or positional relationship shown. They are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0048] It should be understood that in the present application, "electrically connected" can be understood as physical contact and electrical conduction of components; it can also be understood as a form of connection between different components in a circuit structure through physical lines such as copper foils or wires of a printed circuit board (PCB) that can transmit electrical signals. "Communication connection" can refer to electrical signal transmission, including wireless communication connection and wired communication connection. Wireless communication connection does not require a physical medium and does not belong to the connection relationship that limits the product structure. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship, that is, A is connected to B or A is connected with B can mean that there are fastening components (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and it is difficult to separate A and B.

[0049] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those of ordinary skill in the art.

[0050] In the related art, for a foldable electronic device, the support structure is mainly divided into three parts, the body on both sides and the rotating shaft structure in the middle; the left and right body parts are used to fix the foldable display screen, and the folding of the foldable display screen is realized by the rotation of the rotating shaft structure. Usually, the rotating shaft structure is a symmetrical structure, and the left and right structures are synchronously driven through the synchronous gear in the middle.

[0051] Due to the non-extensibility of the foldable display screen, in order to complete the folding and unfolding of the foldable display screen, a certain relative sliding margin needs to be reserved between the left and right body parts, which results in that the left and right body parts of the foldable electronic device cannot be completely limited. When the foldable electronic device is in a falling scenario in the folded state, if the rotating shaft structure touches the ground first, the rotating shaft structure will hit the ground immediately. Under the action of inertia, the left and right body parts will continue to impact the ground relative to the rotating shaft structure, resulting in a dislocation, causing the screen-containing space inside the rotating shaft structure to be compressed, and the bent part of the foldable display screen will be subjected to a large degree of impact and extrusion, thereby leading to problems such as deformation and damage of the foldable display screen.

[0052] Therefore, this application provides a rotating shaft structure. When the connecting piece and the fixing piece have an impact dislocation, the damping structure is used to consume and reduce the kinetic energy between the connecting piece and the fixing piece, reduce the dislocation distance between the connecting piece and the fixing piece, avoid the rapid compression of the screen-containing space inside the rotating shaft structure, prevent the bent part of the foldable display screen from being impacted and extruded, and prevent problems such as deformation and damage of the foldable display screen.

[0053] This application provides a foldable electronic device. Specifically, the foldable electronic device can be any one of mobile or portable computer system devices. Specifically, it can be a mobile phone or a smart phone (for example, a phone based on iPhone TM, a phone based on Android TM), a portable game device (for example, Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop computer, a PDA, a portable Internet device, etc.

[0054] In some cases, the foldable electronic device can perform multiple functions (for example, playing music, displaying videos, storing pictures, and receiving and sending phone calls).

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0056] On the one hand, in combination with Figure 1 As shown, this embodiment provides a rotating shaft structure, which includes: a support assembly 1, a fixing member 2, and a connecting assembly 3.

[0057] The connecting assembly 3 includes a connecting member 31 and a damping structure 32; one end of the connecting member 31 is movably connected to the support assembly 1, and the other end of the connecting member 31 is slidably connected to the fixing member 2; the damping structure 32 is connected between the connecting member 31 and the fixing member 2.

[0058] The rotating shaft structure of this embodiment includes a support assembly 1, a fixing member 2, and a connecting assembly 3, wherein the connecting assembly 3 includes a connecting member 31 and a damping structure 32. The damping structure 32 is connected between the connecting member 31 and the fixing member 2. When the connecting member 31 and the fixing member 2 have an impact and dislocation, the damping structure 32 can consume and reduce the movement energy between the connecting member 31 and the fixing member 2, reduce the dislocation distance between the connecting member 31 and the fixing member 2, avoid the rapid compression of the screen-containing space inside the rotating shaft structure, prevent the bending part of the folding display screen from being impacted and squeezed, and prevent problems such as deformation and damage of the folding display screen.

[0059] In some possible implementation manners, referring to Figure 4 or 5, the rotating shaft structure includes two fixing members 2 and two sets of connecting assemblies 3. The two fixing members 2 are respectively located on both sides of the support assembly 1, and each fixing member 2 is connected to the support assembly 1 through a set of connecting assemblies 3. The rotating shaft structure includes an unfolded state (referring to Figure 5 as shown) and a closed state (referring to Figure 4 as shown). In the closed state, the two fixing members 2 are spaced above the support assembly 1, and the area between the two fixing members 2 forms a screen-containing space.

[0060] Among them, the unfolded state corresponds to the unfolded state of the foldable electronic device. At this time, the folding display screen is in a flat state and has a large display area; the closed state corresponds to the closed state of the foldable electronic device. At this time, the folding display screen is in a folded state, and the bending part of the folding display screen is located in the screen-containing space of the rotating shaft structure.

[0061] In addition, referring to Figure 4 , 5 as shown, the foldable electronic device includes a first side body 4 and a second side body 5. Among them, the first side body 4 is connected to one fixing member 2, the second side body 5 is connected to the other fixing member 2, and the first side body 4 and the second side body 5 respectively rotate around the support assembly 1 driven by the fixing member 2 to realize the switching between the unfolded state and the closed state of the foldable electronic device.

[0062] In combination with Figure 1As shown, in some embodiments, the connecting member 31 is slidably connected to the fixing member 2 in the first direction A, and the damping structure 32 is configured to absorb the impact load between the fixing member 2 and the connecting member 31 in the first direction A.

[0063] With the above arrangement, when the foldable electronic device is in a falling scenario in the folded state, if the hinge structure contacts the ground first, the hinge structure hits the ground immediately. Due to inertia, the left and right body parts will continue to impact the ground relative to the hinge structure, resulting in a dislocation in the first direction A. The damping structure 32 can absorb the impact load in the first direction A, thereby preventing the internal screen space of the hinge structure from being compressed, and further avoiding problems such as deformation and damage of the foldable display screen.

[0064] Combined Figure 1 with Figure 2 As shown, in some embodiments, the damping structure 32 includes a damping member 321 and a damping cavity 322.

[0065] The damping member 321 is movably disposed in the damping cavity 322. The damping member 321 divides the damping cavity 322 into at least two sub-cavities 3221. The damping cavity 322 is filled with a damping medium. At least one damping hole 3211 is provided on the damping member 321, and the damping hole 3211 communicates with at least two sub-cavities 3221.

[0066] With the above arrangement, the damping structure 32 includes a damping member 321 and a damping cavity 322. The damping member 321 can move in the damping cavity 322 and divides the damping cavity 322 into at least two sub-cavities 3221. The damping medium in the damping cavity 322 can flow through the damping hole 3211 on the damping member 321 in the at least two sub-cavities 3221. For Figure 1 example, the damping member 321 divides the damping cavity 322 into two vertically distributed sub-cavities 3221, and the damping holes 3211 on the damping member 321 are arranged in the vertical direction. Figure 1 In this case, the damping member 321 is located at the lower end of the damping cavity 322. The upper sub-cavity 3221 has a larger volume, and the lower sub-cavity 3221 has a smaller volume (approaching zero). If an impact load in the first direction A is generated between the fixing member 2 and the connecting member 31 at this time, the damping member 321 has a tendency to move upward. The damping medium in the upper sub-cavity 3221 is compressed, and the impact load is converted into the pressure of the damping medium. However, the damping medium can only slowly flow downward through the damping hole 3211 on the damping member 321 and cannot dissipate quickly. Therefore, the damping medium in the upper sub-cavity 3221 will generate a damping force that hinders the dislocation movement of the fixing member 2 and the connecting member 31 in the first direction A.

[0067] During the operation of the normal closed state and unfolded state of the rotating shaft structure, the acting forces on the fixing member 2 and the connecting member 31 are continuous loads. Under the action of the continuous loads, the damping medium can flow downward into the sub-chamber 3221 through the damping hole 3211, reducing the damping medium in the upper sub-chamber 3221, and enabling the damping member 321 to move further upward.

[0068] In some possible implementation manners, the damping medium is a liquid damping material, and the types of the damping medium include but are not limited to hydraulic oil, lubricating oil, and the like.

[0069] Combined with Figure 1 and Figure 2 As shown, in some embodiments, the damping member 321 is movably disposed in the damping chamber 322 along the first direction A, and the damping member 321 divides the damping chamber 322 into at least two sub-chambers 3221 distributed along the first direction A.

[0070] Through the above arrangement, during the movement of the damping member 321 in at least two sub-chambers 3221 towards both ends of the first direction A, it can absorb the impact load by using the damping medium therein, achieving the purpose of reducing the movement energy between the connecting member 31 and the fixing member 2 and reducing the misalignment distance between the connecting member 31 and the fixing member 2.

[0071] In some embodiments, the damping member 321 is connected to one of the connecting member 31 and the fixing member 2, and the damping chamber 322 is formed in the other of the connecting member 31 and the fixing member 2.

[0072] Exemplarily, the damping member 321 is connected to the connecting member 31, and the damping chamber 322 is located in the fixing member 2 (as shown in Figure 1 ); or, the damping member 321 is connected to the fixing member 2, and the damping chamber 322 is located in the connecting member 31 (not shown in the figure).

[0073] Combined with Figure 2 and Figure 3 As shown, in some embodiments, the damping member 321 includes a working portion 3212 and a connecting portion 3213; the working portion 3212 is movably disposed in the damping chamber 322, the working portion 3212 divides the damping chamber 322 into at least two sub-chambers 3221, and the damping hole 3211 is located on the working portion 3212.

[0074] The connecting portion 3213 is connected to the working portion 3212, and at least a part of the connecting portion 3213 extends outside the damping chamber 322 to connect the connecting member 31.

[0075] The damping member 321 of this embodiment includes a working portion 3212 and a connecting portion 3213. The function of the working portion 3212 is to be movably arranged in the damping cavity 322, dividing the damping cavity 322 into at least two sub-cavities 3221. The connecting portion 3213 is connected to the working portion 3212 and extends to the outside of the damping cavity 322 to realize the connection between the damping member 321 and the connecting member 31.

[0076] Combined Figure 1 、 Figure 2 and Figure 3 As shown in the figures, in some embodiments, the working portion 3212 moves in the damping cavity 322 along the first direction A, and at least two sub-cavities 3221 are respectively located on both sides of the working portion 3212 along the first direction A.

[0077] The damping cavity 322 is provided with an avoidance opening 3222, and at least a part of the connecting portion 3213 extends to the outside of the damping cavity 322 through the avoidance opening 3222.

[0078] The damping member 321 in this embodiment includes a working portion 3212 and a connecting portion 3213. One end of the connecting portion 3213 is connected to the working portion 3212, and the other end extends to the outside of the damping cavity 322 through the avoidance opening 3222 of the damping cavity 322 to connect the connecting member 31.

[0079] In some embodiments, the length of the avoidance opening 3222 along the first direction A is L1, and the distance between one end of the working portion 3212 along the first direction A and the connecting portion 3213 is L2, where L1 is less than L2.

[0080] Taking Figure 1 and Figure 2 the shown damping structure 32 as an example, when the working portion 3212 moves downward until the connecting portion 3213 abuts against the lower edge of the avoidance opening 3222, in order to ensure that the upper sub-cavity 3221 maintains a sealed state, the upper end of the working portion 3212 needs to remain above the upper edge of the avoidance opening 3222. Therefore, it is necessary to limit that the length L1 of the avoidance opening 3222 and the distance L2 between the end of the working portion 3212 and the working portion 3212 satisfy the above size relationship.

[0081] Exemplarily, the distance L2 is the maximum distance between one end of the working portion 3212 along the first direction A and the connecting portion 3213. Taking Figure 1 as an example, the distance L2 is the vertical distance between the upper edge of the working portion 3212 and the lower edge of the connecting portion 3213.

[0082] Combined Figure 3 As shown in the figures, in some embodiments, a sealing groove 3214 is provided on the outer wall surface of the working portion 3212, and a sealing member (not shown in the figure) is provided in the sealing groove 3214.

[0083] To improve the sealing effect between the working part 3212 and the damping cavity 322, so that the damping medium can only flow in at least two sub-cavities 3221 through the damping holes 3211, a sealing groove 3214 is arranged on the outer wall surface of the working part 3212, and a sealing member is arranged in the sealing groove 3214, which can improve the sealing effect between the working part 3212 and the damping cavity 322.

[0084] Exemplarily, the sealing member is a rubber sealing ring.

[0085] Combined with Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the damping cavity 322 is located in the fixing member 2 and extends along the first direction A; the damping member 321 is connected to the connecting member 31, and the damping member 321 moves along the first direction A with the connecting member 31.

[0086] In this embodiment, the fixing member 2 is arranged in the damping cavity 322, considering that the fixing member 2 has a relatively large volume while the connecting member 31 has a relatively small volume. The fixing member 2 has sufficient volume to accommodate the damping cavity 322 without adversely affecting the structural strength of the fixing member 2, reducing the layout difficulty of the damping cavity 322.

[0087] Combined with Figure 1 As shown, in some embodiments, the support assembly 1 is provided with a rotating shaft member 11, and the end of the connecting member 31 is inserted through the rotating shaft member 11; thereby, the connecting member 31 can drive the fixing member 2 to rotate around the rotating shaft member 11, realizing the switching between the closed state and the unfolded state of the rotating shaft structure.

[0088] Combined with Figure 1 As shown, in some embodiments, one end of the connecting member 31 facing the fixing member 2 is provided with a first sliding portion 311, and the fixing member 2 is provided with a second sliding portion 21, and the first sliding portion 311 is in sliding fit with the second sliding portion 21.

[0089] By using the sliding fit between the first sliding portion 311 and the second sliding portion 21, there is a reserved space for relative movement between the connecting member 31 and the fixing member 2, which can meet the size compensation for the folding display screen during the state switching process of the foldable electronic device.

[0090] In some possible implementation manners, one of the first sliding portion 311 and the second sliding portion 21 is a groove structure, and the other of the first sliding portion 311 and the second sliding portion 21 is a protrusion structure. Exemplarily, the first sliding portion 311 is a protrusion structure, and the second sliding portion 21 is a groove structure.

[0092] In some possible implementation manners, the foldable electronic device further includes a screen module. Optionally, the foldable electronic device is an in-fold type or an out-fold type.

[0093] In some possible implementation manners, the screen module includes a flexible display panel, and the flexible display panel is an organic light-emitting diode display screen (Organic Light-Emitting Diode, OLED).

[0094] Exemplarily, the flexible display panel includes a substrate, an organic light-emitting diode (Organic Light-Emitting Diode, OLED) layer, and a thin film encapsulation (Thin Film Encapsulation, TFE) layer that are sequentially stacked.
