TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, in particular to a rotating shaft assembly and an electronic device. BACKGROUND

[0002] With the continuous development and popularization of electronic devices, electronic devices have become an indispensable part of people's daily life and work, and people's requirements for electronic devices are also getting higher and higher. For example, some mobile phones add a rotating shaft mechanism on the basis of the original, so that the mobile phone can switch between flat and folded forms to bring different user experiences. However, the rotating shaft mechanism used in the existing folding mobile phone is often large in stacking thickness, which limits the overall thickness of the mobile phone and cannot be further thinned. Therefore, how to reduce the stacking thickness of the rotating shaft mechanism has become the main concern of industry personnel. SUMMARY

[0003] The present application provides a rotating shaft assembly, which comprises a base, a rotating piece rotationally connected with the base, and a connecting bracket inserted with the rotating piece; the connecting bracket has a slot for inserting the rotating piece, and the slot wall has a first limiting surface and a second limiting surface located in the rotating direction of the rotating piece; the first limiting surface and the second limiting surface are opposite in direction and located in the same plane; when the rotating piece rotates around the base, the rotating piece abuts against the first limiting surface or the second limiting surface to drive the connecting bracket to rotate around the base.

[0004] The present application provides an electronic device, which comprises a housing assembly and the above-mentioned rotating shaft assembly; the rotating shaft assembly is arranged on the housing assembly along an axis and is configured to drive the housing assembly to fold along the axis.

[0005] The rotating shaft assembly provided by the present application has the slot for inserting the rotating piece in the connecting bracket, and the slot wall has the first limiting surface and the second limiting surface opposite in direction and located in the same plane, so that the first limiting surface and the second limiting surface can be arranged in a staggered manner to be driven by the rotating piece to rotate the connecting bracket around the base in two opposite directions. By such arrangement, compared with the scheme that the first limiting surface and the second limiting surface are parallel, the part of the wall thickness between the first limiting surface and the second limiting surface after assembling the rotating piece and the connecting bracket can be omitted, so as to reduce the stacking thickness of the rotating shaft assembly.

Similarly, the examples below are merely some of the embodiments of the present application and all other embodiments obtained by those skilled in the art without creative efforts based on the embodiments disclosed herein belong to the scope of the present application.

[0039] Reference to an "embodiment" in this application means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that the embodiments described herein are merely examples from a multitude of possible embodiments.

[0040] Please refer to Figures 1-3 , Figure 1 is a structural schematic diagram of an electronic device 10 in a folded state in the embodiment, Figure 2 is Figure 1 a structural schematic diagram of an electronic device 10 in a folded state in the embodiment, Figure 3 is Figure 1 a structural schematic diagram of an electronic device 10 in a folded state in the embodiment.

[0041] The electronic device 10 provided by the embodiment can be a foldable mobile phone, a foldable tablet computer, a foldable personal digital assistant, and a foldable electronic book reader, etc. In the following, only the electronic device 10 as a foldable mobile phone is described. As shown in Figures 1-3 , the electronic device 10 can include a display assembly 100, a housing assembly 200, and a hinge assembly 300. The display assembly 100 is arranged on the housing assembly 200 and can realize the function of image display, and the housing assembly 200 can be used to mount various functional devices required by the display assembly 100. The hinge assembly 300 is arranged on the housing assembly 200 along the axis Y and can drive the display assembly 100 and the housing assembly 200 to fold along the axis Y, so that the electronic device 10 can be switched from a flat state to a folded state. In the embodiment, the hinge assembly 300 has the advantage of small stacking thickness, which is conducive to the thin design of the electronic device 10.

[0042] The display assembly 100 is flexible and can be folded along the axis Y under the driving of the housing assembly 200. For example, the display assembly 100 can include a transparent cover, a touch panel, and a display panel which are sequentially stacked. The surface of the transparent cover can have a smooth and flat characteristic to facilitate the touch operation of the user, such as clicking, sliding, pressing, etc., and the transparent cover is made of a flexible material such as colorless polyimide (CPI). The touch panel is arranged between the transparent cover and the display panel, and is used to respond to the touch operation of the user and convert the corresponding touch operation into an electrical signal transmitted to the processor of the electronic device 10, so that the electronic device 10 can make a corresponding response to the touch operation of the user. The display panel is mainly used for displaying a picture and can be used as an interactive interface to instruct the user to perform the above-mentioned touch operation on the transparent cover, and the display panel can use an OLED (Organic Light-Emitting Diode) screen to realize the image display and folding function of the electronic device 10. In this embodiment, the transparent cover, the touch panel, and the display panel can be attached together by means of OCA (Optically Clear Adhesive), PSA (Pressure Sensitive Adhesive), or other adhesives.

[0043] It can be understood that the specific structure of the aforementioned display assembly 100 is only an example, and in other embodiments, the display assembly 100 can not be limited to the structure shown in the foregoing embodiments. That is, the specific structure of the display assembly 100 can also be adaptively selected according to the design requirements of the electronic device 10, as long as the display assembly 100 is flexible and can be folded along the axis Y, which is not limited in this embodiment. In addition, in some embodiments, when the electronic device 10 is a folding device without display function, the design of the display assembly 100 can also be omitted.

[0044] The housing assembly 200 can carry the display assembly 100 and install various functional devices required by the electronic device 10, and the housing assembly 200 can also drive the display assembly 100 to fold along the axis Y. For example, the housing assembly 200 can include a first housing and a second housing which are connected to each other and can be folded along the axis Y. The first housing can be arranged on one side of the electronic device 10, and the second housing can be arranged on the other side of the electronic device 10. The first housing and the second housing can be connected to each other by means of a hinge structure, and the hinge structure can be arranged on the side of the first housing or the second housing. The hinge structure can be a flexible hinge structure, and the hinge structure can be made of a flexible material such as colorless polyimide (CPI). The hinge structure can be arranged on the side of the first housing or the second housing, and the hinge structure can be arranged on the side of the first housing or the second housing. The hinge structure can be arranged on the side of the first housing or the second housing. Figures 1-3As shown, the shell assembly 200 can include a first shell 210 and a second shell 220 divided along the axis Y. The first shell 210 and the second shell 220 are respectively located on opposite sides of the rotation shaft assembly 300 parallel to the axis Y, and are connected with the rotation shaft assembly 300. The first shell 210 and the second shell 220 can also jointly form a bearing surface 400 with the rotation shaft assembly 300, and the display assembly 100 can be arranged on the bearing surface 400 and can be unfolded under the support of the bearing surface 400. At the same time, the first shell 210 and the second shell 220 can be folded along the axis Y under the driving of the rotation shaft assembly 300, and the display assembly 100 can also be folded under the driving of the first shell 210 and the second shell 220, so as to switch the electronic device 10 from the unfolded state to the folded state.

[0045] Further, the electronic device 10 can adopt an inward folding design, so that the folded display assembly 100 is located between the first shell 210 and the second shell 220 to protect the display assembly 100. At the same time, the first shell 210 and the second shell 220 can also be used to install various functional devices required by the electronic device 10, such as batteries, microphones, speakers, cameras, and mainboards, etc. The functional devices installed on the first shell 210 and the functional devices installed on the second shell 220 can be the same or partially the same. For example, the first shell 210 and the second shell 220 can both be installed with a battery to respectively supply power to the functional devices installed on the first shell 210 and the second shell 220. In this embodiment, the first shell 210 and the second shell 220 can also be symmetrically arranged about the axis Y, that is, the axis Y can be a symmetric folding line of the first shell 210 and the second shell 220.

[0046] In some embodiments, the electronic device 10 can also adopt an outward folding design, so that the folded display assembly 100 can be exposed outside the electronic device 10 to provide image display function in the folded state. At the same time, the first shell 210 and the second shell 220 can also not be limited to be symmetrically arranged about the axis Y, that is, the axis Y can also be an asymmetric folding line of the electronic device 10, as long as the first shell 210 and the second shell 220 can be folded along the axis Y. In addition, the axis Y can not only be placed longitudinally as shown in Figure 1 and Figure 2 , so that the electronic device 10 can be folded left and right based on the axis Y, and the axis Y can also be placed horizontally, so that the electronic device 10 can be folded up and down based on the axis Y.

[0047] Please refer to Figures 4-5 , Figure 4 is Figure 1 the partial sectional structure diagram of the shell assembly 200 and the rotation shaft assembly 300 along V-V in Figure 5 is Figure 2A schematic diagram of a partial cross-sectional structure of the middle housing assembly 200 and the rotating shaft assembly 300 along line VI-VI.

[0048] When the electronic device 10 is in a flattened state, the hinge assembly 300 can be hidden inside the electronic device 10, and when the electronic device 10 is in a folded state, the hinge assembly 300 can be exposed outside the electronic device 10. Figures 4-5 As shown, when the electronic device 10 is in a flattened state, the first housing 210 and the second housing 220 can also be spliced ​​together on the side opposite to the bearing surface 400, covering the hinge assembly 300, and the first housing 210 and the second housing 220 can also jointly constitute part of the external structure of the electronic device 10. When the electronic device 10 is in a folded state, the first housing 210 and the second housing 220 can also overlap with opposite sides of the hinge assembly 300 parallel to the axis Y, and together with the hinge assembly 300, constitute part of the external structure of the electronic device 10. This arrangement can ensure the airtightness of the electronic device 10 in both the flattened and folded states without adding additional structural components, thus preventing the internal structure of the electronic device 10 from being exposed.

[0049] Specifically, the first housing 210 may include a first middle frame 211, and the second housing 220 may include a second middle frame 221. When the electronic device 10 is in a flattened state, the first middle frame 211 and the second middle frame 221 can be joined at the Y-axis, and the joint can be recessed to form a receiving space 500. The hinge assembly 300 can be disposed within the receiving space 500 and connected to the first middle frame 211 and the second middle frame 221 respectively. Simultaneously, the side of the hinge assembly 300 exposed outside the receiving space 500 can be flush or nearly flush (slightly convex or slightly concave) with the first middle frame 211 and the second middle frame 221, thus forming the aforementioned bearing surface 400 together. With this configuration, the hinge assembly 300 can be hidden inside the electronic device 10, and the first middle frame 211 and the second middle frame 221 can together constitute part of the external structure of the electronic device 10.

[0050] Further, when the electronic device 10 is in the folded state, the first middle frame 211 and the second middle frame 221 can be folded along the axis Y, and the spliced part of the first middle frame 211 and the second middle frame 221 can be separated, so that the hinge assembly 300 can be exposed outside the electronic device 10. At the same time, the first middle frame 211 and the second middle frame 221 can also be respectively connected with the opposite sides of the hinge assembly 300 parallel to the axis Y, so as to avoid the problem that the internal structure of the electronic device 10 is exposed from the gap between the first middle frame 211 and the hinge assembly 300 and the gap between the second middle frame 221 and the hinge assembly 300. In this way, the hinge assembly 300 can be exposed outside the electronic device 10 and together with the first middle frame 211 and the second middle frame 221 form part of the appearance structure of the electronic device.

[0051] In some embodiments, the first shell 210 and the second shell 220 can also not be limited to the structure shown in the foregoing embodiments. That is, the first shell 210 is not limited to only including the first middle frame 211, and the second shell 220 is not limited to only including the second middle frame 221. For example, the first shell 210 can further include a first back cover 212 covering the side of the first middle frame 211 away from the bearing surface 400, and the second shell 220 can further include a second back cover 222 covering the side of the second middle frame 221 away from the bearing surface 400, and the first back cover 212 and the second back cover 222 can together with the first middle frame 211 and the second middle frame 221 respectively form a containing space to install various functional devices required by the electronic device 10. In addition, the first back cover 212 and the second back cover 222 can replace or partially replace the first middle frame 211 and the second middle frame 221 to shield the hinge assembly 300 when the electronic device 10 is in the unfolded state, and together with the hinge assembly 300 form part of the appearance structure of the electronic device 10 when the electronic device 10 is in the folded state.

[0052] In some embodiments, when the electronic device 10 is in the unfolded state, the first middle frame 211 and the second middle frame 221 can also have a certain gap without being spliced together without a gap. At this time, the area close to the gap of the first middle frame 211 and the second middle frame 221 can still be recessed to form the foregoing containing space 500, and the hinge assembly 300 can still be arranged in the containing space 500 and can shield the gap. The gap can be formed by design tolerance or can be a preset clearance. In the two cases, the gap is generally small, so that the exposure of the hinge assembly 300 at the gap is limited, and therefore the hinge assembly 300 can be regarded as hidden in the electronic device 10.

[0053] In some embodiments, the gap can also be designed to be larger in consideration of different design requirements, and in this case, part of the hinge assembly 300 can be exposed outside the electronic device 10 through the gap and together with the first middle frame 211 and the second middle frame 221 to form part of the appearance structure of the electronic device 10 regardless of whether the electronic device 10 is in the unfolded state or the folded state.

[0054] In some embodiments, in addition to using the hinge assembly 300 together with the first housing 210 and the second housing 220 to form part of the appearance structure of the electronic device 10, a shielding structure (such as leather) can also be arranged between the first housing 210 and the second housing 220 to shield the hinge assembly 300. In this way, regardless of whether the electronic device 10 is in the unfolded state or the folded state, the hinge assembly 300 can be hidden inside the electronic device 10, and the first housing 210, the second housing 220, and the shielding structure can together form part of the appearance structure of the electronic device 10.

[0055] Please refer to Figures 4-5 Please refer to Figures 6-7 , Figure 6 is Figure 3 the exploded structure diagram of the hinge assembly 300 in FIG. 1, Figure 7 is Figure 6 the connection structure diagram of the base 310, the rotating piece 320, the connecting bracket 330, and the rotating piece 360 in the first position in FIG. 2.

[0056] The hinge assembly 300 is arranged between the first housing 210 and the second housing 220 along the axis Y and connected with the first housing 210 and the second housing 220 respectively, and can drive the first housing 210 and the second housing 220 to fold along the axis Y. For example, Figures 4-6As shown, the rotating shaft assembly 300 can include a base 310, rotating members 320, and connecting supports 330. The base 310 can be disposed between the first housing 210 and the second housing 220 along the axis Y and can be rotationally connected with the rotating members 320, so that the rotating members 320 can rotate around the base 310 with the direction parallel to the axis Y as the rotating axis direction. The connecting supports 330 are inserted with the rotating members 320 and can rotate around the base 310 under the driving of the rotating members 320, and the base 310 has a set of rotating members 320 and connecting supports 330 on each side parallel to the axis Y. The first housing 210 and the second housing 220 can be connected with the two connecting supports 330 respectively to rotate around the base 310 under the driving of the two connecting supports 330, so that the first housing 210 and the second housing 220 can be folded along the axis Y. In this embodiment, the rotating members 320 and the connecting supports 330 have the advantage of small stacking thickness, so that the overall stacking thickness of the rotating shaft assembly 300 can be reduced, which is beneficial to the thin design of the electronic device 10 as a whole.

[0057] The base 310 is disposed between the first housing 210 and the second housing 220 along the axis Y and is used to connect and fix various structural members of the rotating shaft assembly 300. As shown, Figures 4-6 The number of the base 310 can be multiple, and the multiple bases 310 can be disposed between the first housing 210 and the second housing 220 along the axis Y. The distance between any two adjacent bases 310 of the multiple bases 310 can be the same or different, and the space between the two adjacent bases 310 can be used for wiring (such as a flexible circuit board) to realize the electrical connection between the functional devices respectively installed on the first housing 210 and the second housing 220. For example, the number of the base 310 can be three, and the three bases 310 can be disposed at the top, middle and bottom of the first housing 210 and the second housing 220 along the axis Y, and the distance between any two adjacent bases 310 of the three bases 310 is the same. In this embodiment, each base 310 has a set of rotating members 320 and connecting supports 330 on each side parallel to the axis Y, so as to improve the rotating stability of the first housing 210 and the second housing 220 by using multiple sets of rotating members 320 and connecting supports 330.

[0058] In some embodiments, the number of the bases 310 can also not be limited to three, and the number of the bases 310 can also be two, four, five or more. That is, the number of the bases 310 can be adaptively selected according to the design requirements (such as size, etc.) of the electronic device 10, and the embodiments are not limited thereto. In some embodiments, a plurality of bases 310 can also be connected to form a whole, to constitute a larger base 310 (equivalent to the number of the base 310 being one). At this time, the base 310 can also form a via for wiring, to realize the electrical connection between the functional devices respectively mounted on the first shell 210 and the second shell 220.

[0059] In order to realize the rotational connection of the base 310 and the rotating member 320, the rotating shaft assembly 300 can further include a rotating shaft 340. As shown in Figure 4 、 Figure 5 and Figure 7 , the rotating shaft 340 is arranged on the base 310, and the axial direction of the rotating shaft 340 is parallel to the axis Y. Among them, the rotating member 320 can be sleeved on the rotating shaft 340, and the rotating member 320 is rotatably connected to the base 310 through the rotating shaft 340. For example, the rotating shaft 340 can rotate relative to the base 310, and the rotating member 320 can be tightly sleeved on the rotating shaft 340, so that the rotating member 320 can rotate around the base 310 under the driving of the rotating shaft 340. Of course, in some embodiments, the rotating shaft 340 can be tightly fixed on the base 310, and the rotating member 320 can rotate relative to the rotating shaft 340, to realize the rotational connection of the rotating member 320 and the base 310.

[0060] Further, in order to realize the rotational connection of the two rotating members 320 and the base 310, the number of the rotating shafts 340 can also be two, and the two rotating shafts 340 can be symmetrically arranged about the axis Y, and the two rotating members 320 can be sleeved on the two rotating shafts 340 respectively, and the two rotating members 320 are rotatably connected to the base 310 through the rotating shafts 340. In the embodiment, in addition to the two rotating shafts 340 being symmetrically arranged about the axis Y, the two rotating members 320 and the two connecting supports 330 can also be symmetrically arranged about the axis Y. Of course, in some embodiments, the two rotating shafts 340, the two rotating members 320 and the two connecting supports 330 can also be asymmetrically arranged, as long as the rotating member 320 can drive the connecting support 330 to rotate around the base 310 through the rotating shaft 340, and the embodiments are not limited thereto.

[0061] In some embodiments, in addition to the rotating connection of the base 310 and the rotating member 320 through the rotating shaft 340, an arc-shaped sliding groove can also be arranged on the base 310, and a part of the rotating member 320 can be arranged in the arc-shaped sliding groove and can slide in the arc-shaped sliding groove, so that the sliding track of the rotating member 320 can be an arc, thereby realizing the rotation of the rotating member 320 around the base 310. Of course, in addition to the above two rotating modes, the rotating member 320 and the base 310 can adopt various rotating modes, as long as the rotating member 320 can rotate around the base 310, and the embodiments will not be listed one by one here.

[0062] Please combine Figure 7 Please refer to Figures 8-11 , Figure 8 is Figure 6 the connecting structure diagram of the base 310, the rotating member 320, the connecting support 330 and the rotating member 360 in the second position, Figure 9 is Figure 8 the structure diagram of the rotating member 320, Figure 10 is Figure 7 the partial sectional structure diagram of the rotating member 320 and the connecting support 330 along VII-VII in the second position, Figure 11 is Figure 8 another structure diagram of the rotating member 320.

[0063] The rotating member 320 is rotationally connected with the base 310, and the rotating member 320 can also be inserted on the connecting support 330 and can drive the connecting support 330 to rotate around the base 310. As shown in Figures 7-8 , the rotating member 320 is sleeved on the rotating shaft 340 and can be rotated by the rotating shaft 340 around the base 310 from the first position to the second position. When the rotating member 320 is located at the first position, the first shell 210 and the second shell 220 can be unfolded, so that the electronic device 10 can be in an unfolded state. When the rotating member 320 is at the second position, the first shell 210 and the second shell 220 can be folded, so that the electronic device 10 can be in a folded state. Meanwhile, the two rotating members 320 located at the opposite sides of the base 310 can also rotate synchronously, and the directions of rotation of the two rotating members 320 are opposite. For example, the base 310 can be provided with two meshing synchronous gears 311, and the two rotating members 320 can be meshed with the two synchronous gears 311 respectively, so that the two rotating members 320 can rotate synchronously through the two synchronous gears 311.

[0064] Further, the rotating member 320 is inserted in the connecting support 330, and the rotating member 320 also has a first matching surface 321 and a second matching surface 322 which can abut against the connecting support 330, so that the connecting support 330 can be driven to rotate by the rotating member 320. As shown in Figures 9-10As shown, the rotating member 320 has a first matching surface 321 and a second matching surface 322 on opposite sides in the rotating direction, and the first matching surface 321 and the second matching surface 322 are located in the same plane, so that the first matching surface 321 and the second matching surface 322 can be arranged in a staggered manner. Meanwhile, when the rotating member 320 rotates from the first position to the second position, the connecting bracket 330 can abut against the first matching surface 321 and rotate around the base 310 under the driving of the rotating member 320. When the rotating member 320 rotates from the second position to the first position, the connecting bracket 330 can abut against the second matching surface 322 and rotate in the opposite direction around the base 320 under the driving of the rotating member 320.

[0065] Alternatively, in addition to being a plane, the first matching surface 321 and the second matching surface 322 can also be arc surfaces and located in the same arc surface. For example, the first matching surface 321 can be concave, and the second matching surface 322 can be convex, to form two arc surfaces with the same bending direction and arc. Meanwhile, the first matching surface 321 and the second matching surface 322 can also be symmetrically arranged on the rotating member 320 to improve the consistency of the abutment between the first matching surface 321 and the second matching surface 322 and the connecting bracket 330. In some embodiments, considering different design requirements, the first matching surface 321 and the second matching surface 322 can also not be limited to symmetric arrangement, and only need to maintain the same height, which is not limited in the embodiment.

[0066] Through the above arrangement, since the first matching surface 321 and the second matching surface 322 face in opposite directions and are located in the same plane, the first matching surface 321 and the second matching surface 322 can be arranged in a staggered manner, and the rotating member 320 can drive the connecting bracket 330 to rotate around the base 310 in two opposite directions through the first matching surface 321 and the second matching surface 322, respectively. Compared with the parallel arrangement of the first matching surface 321 and the second matching surface 322, the rotating member 320 and the connecting bracket 330 in the embodiment can omit the part of the wall thickness located between the first matching surface 321 and the second matching surface 322 after assembly, to reduce the stacking thickness of the rotating member 320 and the connecting bracket 330.

[0067] Exemplarily, the rotating member 320 can include a sleeve portion 323, a connecting portion 324, and a plug-in portion 325. As shown, the sleeve portion 323 is arranged on the base 310 and can be sleeved with the connecting portion 324. Figures 7-10As shown, the sleeve portion 323 can be sleeved on the rotating shaft 340 and can rotate around the base 310 under the driving of the rotating shaft 340, and the sleeve portion 323 can also be in contact with the base 310 parallel to the axis Y, so that the base 310 can limit the sleeve portion 323 to avoid axial movement of the sleeve portion 323 on the rotating shaft 340. The connecting portion 324 is connected to the side of the sleeve portion 323 away from the rotating shaft 340, and is connected to the plug-in portion 325 after being arranged to extend away from the rotating shaft 340, and the connecting portion 324 can also be bent during extension to avoid other structural members of the rotating shaft assembly 300. The plug-in portion 325 can be inserted into the connecting bracket 330, and the plug-in portion 325 has the first mating surface 321 and the second mating surface 322 on the opposite sides thereof, respectively, to drive the connecting bracket 330 to rotate in two opposite directions. In this embodiment, the material of the rotating member 320 can be plastic, and the sleeve portion 323, the connecting portion 324 and the plug-in portion 325 can be integrally formed by in-mold injection.

[0068] In some embodiments, the rotating member 320 can also not be limited to including the sleeve portion 323, the connecting portion 324 and the plug-in portion 325. For example, when the rotating member 320 and the base 310 are rotationally connected by using the above-mentioned arc-shaped sliding groove, the design of the sleeve portion 323 can also be omitted. At this time, the connecting portion 324 can be formed with an arc-shaped structure matching the arc-shaped sliding groove, so that the connecting portion 324 can be matched with the arc-shaped sliding groove by using the arc-shaped structure to realize the rotational connection between the connecting portion 324 and the base 310.

[0069] Further, the plug-in portion 325 can include a top wall 326 and a bottom wall 327 arranged opposite to each other in the rotating direction of the rotating member 320, and a side wall 328 connected to the top wall 326 and the bottom wall 327 and arranged around the top wall 326 and the bottom wall 327. The top wall 326 is provided with a first matching groove 3261, and the bottom wall of the first matching groove 3261 has the first mating surface 321. The bottom wall 327 is provided with a second matching groove 3271, and the bottom wall of the second matching groove 3271 has the second mating surface 322. At the same time, the sum of the depths of the first matching groove 3261 and the second matching groove 3271 is equal to the thickness of the plug-in portion 325, so that the first mating surface 321 and the second mating surface 322 not only have opposite orientations, but also can be located in the same plane.

[0070] Furthermore, the sidewall 328 may include: a first sidewall 3281 and a second sidewall 3282 disposed opposite to each other in the insertion direction X, and a third sidewall 3283 and a fourth sidewall 3284 disposed opposite to each other in a direction perpendicular to the insertion direction X. To avoid obstructing the connecting bracket 330, the first mating groove 3261 and the second mating groove 3271 may also penetrate through opposite sides of the insertion portion 325 in the insertion direction X, that is, through the first sidewall 3281 and the second sidewall 3282. The connecting bracket 330 can then be assembled from the first sidewall 3281 into the first mating groove 3261 and the second mating groove 3271 to abut against the first mating surface 321 and the second mating surface 322, respectively.

[0071] Furthermore, the first mating groove 3261 can also penetrate the side of the first mating surface 321 away from the second mating surface 322, that is, penetrate the third sidewall 3283. Simultaneously, the second mating groove 3271 can also penetrate the side of the second mating surface 322 away from the first mating surface 321, that is, the fourth sidewall 3284. This arrangement not only allows the penetrating first sidewall 3281 to avoid obstructing the connecting bracket 330, but also allows the penetrating second sidewall 3282, third sidewall 3283, and fourth sidewall 3284 to reduce the volume of the insertion part 325, thereby reducing the space occupied by the insertion part 325. In this embodiment, the aforementioned insertion direction X can refer to the insertion direction of the insertion part 325 and the connecting bracket 330, that is, the direction in which the insertion part 325 inserts into or exits the connecting bracket 330.

[0072] Furthermore, the rotating member 320 may also include two insertion portions 325. For example... Figures 9-10 As shown, two insertion portions 325 can be symmetrically and spaced apart on the connecting portion 324. The two insertion portions 325 can simultaneously insert into the connecting bracket 330 and simultaneously drive the connecting bracket 330 to rotate in two opposite directions. This arrangement allows the rotating member 320 to increase the amount of contact with the connecting bracket 330 using the two insertion portions 325, thereby improving the stability of the contact between the rotating member 320 and the connecting bracket 330.

[0073] In some embodiments, the two plug-in portions 325 may not be symmetrically arranged on the connecting portion 324. It is sufficient that the two plug-in portions 325 can synchronously plug into the connecting bracket 330 and synchronously drive the connecting bracket 330 to rotate. Furthermore, in some embodiments, the number of plug-in portions 325 may not be limited to two. The specific number of plug-in portions 325 can be selected according to design requirements, such as one, three, four, five, or more. This embodiment does not limit this.

[0074] In some embodiments, the first and second mating surfaces 321 and 322 can be arranged to be spaced apart on the insertion portion 325, and the edges of the first and second mating surfaces 321 and 322 close to each other can be overlapped, so that the insertion portion 325 has two parts of the first and second mating surfaces 321 and 322 which can be separated. As shown in Figure 11 , the insertion portion 325 can be divided into a first insertion portion 3251 having the first mating surface 321 and a second insertion portion 3252 having the second mating surface 322, and the first and second insertion portions 3251 and 3252 can be inserted into the connecting bracket 330. At this time, in order to realize the connection of the first and second insertion portions 3251 and 3252, the rotating member 320 can further include a bearing portion 3253 connected to the connecting portion 324, and the first and second insertion portions 3251 and 3252 can be arranged on the same side of the bearing portion 3253 to be integrally connected by the bearing portion 3253.

[0075] Please refer to Figure 10 , Figures 12-15 , Figure 12 is Figure 8 the structure diagram of the connecting bracket 330 in part, Figure 13 is the front view of the rotating member 320 and the connecting bracket 330 in some embodiments, Figure 14 is Figure 7 the structure diagram of another part of the rotating member 320 and the connecting bracket 330 along VII-VII in part, Figure 15 is Figure 7 the structure diagram of a part of the base 310, the rotating member 320 and the connecting bracket 330 along VIII-VIII.

[0076] The connecting bracket 330 is inserted into the rotating member 320 and can be rotated around the base 310 under the driving of the rotating member 320. As shown in Figure 10 and Figure 12As shown, the connecting bracket 330 has a slot 333 for the plug-in part 325 to be inserted, and the slot wall of the slot 333 has a first limiting surface 334 and a second limiting surface 335 located in the rotating direction of the plug-in part 325. Among them, the first limiting surface 334 and the second limiting surface 335 are opposite in direction and located in the same plane, so that the first limiting surface 334 and the second limiting surface 335 can be arranged in a staggered manner. At the same time, when the rotating piece 320 rotates around the base 310, the rotating piece 320 abuts against the first limiting surface 334 or the second limiting surface 335 to drive the connecting bracket 330 to rotate around the base 310. For example, when the rotating piece 320 rotates from the first position to the second position, the plug-in part 325 can abut against the first limiting surface 334 and drive the connecting bracket 330 to rotate around the base 310. When the rotating piece 320 rotates from the second position to the first position, the plug-in part 325 can abut against the second limiting surface 335 and drive the connecting bracket 330 to rotate in the opposite direction around the base 310.

[0077] Further, the first limiting surface 334 can abut against the first matching surface 321, and the second limiting surface 335 can abut against the second matching surface 322, so that the plug-in part 325 can drive the connecting bracket 330 to rotate in two opposite directions. Among them, when the first matching surface 321 and the second matching surface 322 are planes, the first limiting surface 334 and the second limiting surface 335 can also be planes. Similarly, when the first matching surface 321 and the second matching surface 322 are arc surfaces, the first limiting surface 334 and the second limiting surface 335 can also be arc surfaces matched therewith and located in the same arc surface. In addition, the first limiting surface 334 and the second limiting surface 335 can also be symmetrically arranged on the connecting bracket 330 to improve the consistency of the abutment between the first limiting surface 334 and the second limiting surface 335 and the plug-in part 325. In some embodiments, considering different design requirements, the first limiting surface 334 and the second limiting surface 335 can also not be limited to symmetric arrangement, as long as the first limiting surface 334 and the second limiting surface 335 maintain the same height, which is not limited in the embodiment.

[0078] Through the above arrangement, since the first limiting surface 334 and the second limiting surface 335 are opposite in direction and located in the same plane, the first limiting surface 334 and the second limiting surface 335 can also be arranged in a staggered manner, and the rotating piece 320 can drive the connecting bracket 330 to rotate in two opposite directions around the base 310 through the first limiting surface 334 and the second limiting surface 335, respectively. Compared with the scheme that the first limiting surface 334 and the second limiting surface 335 are parallel, the rotating piece 320 and the connecting bracket 330 in the embodiment can omit the part of wall thickness located between the first limiting surface 334 and the second limiting surface 335 after assembly, so as to reduce the stacking thickness of the rotating piece 320 and the connecting bracket 330.

[0079] Specifically, in the scheme where the first limiting surface 334 and the second limiting surface 335 are parallel ( Figure 13 As shown, the stacked structure of the rotating component 320 and the connecting bracket 330 can generally be divided into three layers. The first layer D1 is the insertion part 325, the second layer D2 is a portion of the connecting bracket 330 with the first limiting surface 334, and the third layer D3 is a portion of the connecting bracket 330 with the second limiting surface 335. The stacked thickness of the rotating component 320 and the connecting bracket 330 can be the sum of the wall thicknesses of the first layer D1, the second layer D2, and the third layer D3. In this design, the wall thicknesses of the first layer D1, the second layer D2, and the third layer D3 are often already at their limit and cannot be further reduced, otherwise it would affect the stability of the fit between the insertion part 325 and the connecting bracket 330.

[0080] Based on this, in order to further reduce the stacking thickness of the rotating component 320 and the connecting bracket 330, this embodiment sets the first limiting surface 334 and the second limiting surface 335 to face opposite directions and be located in the same plane, so that the insertion part 325 and the connecting bracket 330 can be misaligned. At this time, the stacking thickness of the rotating component 320 and the connecting bracket 330 can be the sum of the wall thicknesses of the second layer D2 and the third layer D3 ( Figure 10 (As shown). Compared to the scheme where the first limiting surface 334 and the second limiting surface 335 are parallel, in this embodiment, the rotating component 320 and the connecting bracket 330 can omit part of the wall thickness located between the first limiting surface 334 and the second limiting surface 335 (equivalent to omitting the wall thickness of the first layer D1) after assembly, thereby achieving the purpose of reducing the stacking thickness of the rotating component 320 and the connecting bracket 330.

[0081] Furthermore, the connecting bracket 330 also has a first side 331 and a second side 332 located in the rotation direction of the rotating member 320 (plug-in portion 325) and disposed opposite to each other. Since the wall thickness of the second layer D2 and the third layer D3 is often greater than the wall thickness of the first layer D1, the side of the plug-in portion 325 opposite to the first limiting surface 334 and the side of the plug-in portion 325 opposite to the second limiting surface 335 will be respectively blocked by the first side 331 and the second side 332 of the connecting bracket 330. Figure 14 (As shown). At this time, in order to improve the stability of the fit between the plug-in portion 325 and the connecting bracket 330, the side of the plug-in portion 325 facing away from the first limiting surface 334 can also be exposed on the first side 331, and the side of the plug-in portion 325 facing away from the second limiting surface 335 can also be exposed on the second side 332. Figure 10 (As shown). With this configuration, the portion of the connecting bracket 330 that obstructs the insertion part 325 can be omitted, allowing the two portions of the insertion part 325 with the first mating surface 321 and the second mating surface 322 to be thickened. This improves the structural strength of the insertion part 325, thereby enhancing the mating stability between the insertion part 325 and the connecting bracket 330.

[0082] In some embodiments, in addition to the wall thickness of the splicing part 325 can be increased alone, the connecting bracket 330 can also be thickened alone or synchronously, and the wall thickness of both is only required to be less than the wall thickness of the omitted first layer D1. In some embodiments, in addition to the splicing part 325 being exposed on the first side 331 and the second side 332 at the same time, the splicing part 325 can also be exposed only on the first side 331 or the second side 332. That is, only the side of the splicing part 325 facing away from the first limiting surface 334 is exposed on the first side 331, while the side of the splicing part 325 facing away from the second limiting surface 335 is shielded by the connecting bracket 330. Alternatively, only the side of the splicing part 325 facing away from the second limiting surface 335 is exposed on the second side 332, while the side of the splicing part 325 facing away from the first limiting surface 334 is shielded by the connecting bracket 330.

[0083] Further, in order to enable the splicing part 325 to be exposed on the first side 331 and the second side 332, the insertion slot 333 can include a first insertion slot 3331 and a second insertion slot 3332. As shown in Figure 10 and Figure 12 , the first side 331 can be provided with the first insertion slot 3331, and the second side 332 can be provided with the second insertion slot 3332, and the bottom wall of the first insertion slot 3331 has the first limiting surface 334, and the bottom wall of the second insertion slot 3332 has the second limiting surface 335. At the same time, the sum of the depths of the first insertion slot 3331 and the second insertion slot 3332 is equal to the thickness of the connecting bracket 330, so that the first limiting surface 334 and the second limiting surface 335 can be located in the same plane while facing opposite directions. In this way, the side of the splicing part 325 facing away from the first limiting surface 334 can be exposed on the first side 331 through the first insertion slot 3331, and the side of the splicing part 325 facing away from the second limiting surface 335 can be exposed on the second side 332 through the second insertion slot 3332.

[0084] Further, in order to realize the splicing of the splicing part 325 and the connecting bracket 330, the connecting bracket 330 can also include a third side 336 and a fourth side 337. As shown in Figure 12 and Figure 15 , the third side 336 is connected with the first side 331 and the second side 332 respectively, and the fourth side 337 is connected with the first side 331 and the second side 332 respectively, and the third side 336 is arranged opposite to the fourth side 337 in the splicing direction X. Among them, the first insertion slot 3331 and the second insertion slot 3332 can penetrate through the third side 336, and the splicing part 325 can be inserted into the first insertion slot 3331 and the second insertion slot 3332 from the third side 336. At the same time, the first limiting surface 334 and the second limiting surface 335 can be arranged in a spaced manner close to each other, and a gap 3333 communicating the first insertion slot 3331 and the second insertion slot 3332 is formed Figure 12As shown, the first slot 3331 and the second slot 3332 can be connected to form a slot 333 matching the shape of the plug-in part 325, so as to realize the plug-in of the plug-in part 325 and the connecting bracket 330. In addition, the first slot 3331 and the second slot 3332 can also pass through the fourth side 337, so as to reduce the width of the plug-in part 325 and the connecting bracket 330 in the plug-in direction X.

[0085] Further, since the first slot 3331 and the second slot 3332 are connected and pass through the third side 336 and the fourth side 337, the first slot 3331 and the second slot 3332 can divide the connecting bracket 330 into a first part 330a and a second part 330b. As shown, Figure 12 and Figure 15 In order to realize the connection of the first part 330a and the second part 330b, the connecting bracket 330 can also be provided with a connecting rib 330c located in the second slot 3332. The connecting rib 330c can connect the first part 330a and the second part 330b, so that the first part 330a and the second part 330b can be connected to form an integral whole through the connecting rib 330c. At the same time, the connecting rib 330c can be spaced apart from the second limiting surface 335 to form a spacing space 330d to avoid the plug-in part 325, so as to avoid the influence of the connecting rib 330c on the assembly of the plug-in part 325 and the connecting bracket 330. In addition, the connecting rib 330c can be flush with the second side 332 and the fourth side 337, so as to increase the structural strength of the connecting rib 330c and reduce the thickness of the connecting bracket 330 due to the setting of the connecting rib 330c. In the embodiment, the connecting rib 330c can only block part of the area on the side of the plug-in part 325 away from the second limiting surface 335, which is helpful to reduce the weight of the connecting bracket 330 and the manufacturing cost of the connecting bracket 330 compared with the scheme shown in Figure 14

[0086] In some embodiments, in addition to the second slot 3332, the first slot 3331 can also be provided with a connecting rib 330c, or the first slot 3331 and the second slot 3332 can be provided with a connecting rib 330c, so as to further improve the connection reliability of the first part 330a and the second part 330b. In this case, the wall thickness of the connecting bracket 330 due to the connecting rib 330c is less than the wall thickness of the omitted first layer D1, which is not limited in the embodiment. In addition, in some embodiments, the connecting rib 330c can not be limited to be flush with the outer wall surface of the connecting bracket 330.

[0087] ​In some embodiments, since the design of the connecting rib 330c increases the thickness of the connecting bracket 330 to some extent, the first slot 3331 and the second slot 3332 can also only penetrate through the third side 336, and the fourth side 337 is not penetrated by the first slot 3331 and the second slot 3332, so that the connecting bracket 330 can still be kept as a whole without being separated into the first part 330a and the second part 330b.

[0088] In some embodiments, when the first mating surface 321 and the second mating surface 322 overlap with each other at one side, that is, the insertion part 325 is divided into the first insertion part 3251 and the second insertion part 3252, the first limiting surface 334 and the second limiting surface 335 can also overlap with each other at one side, so that the first slot 3331 and the second slot 3332 can be independent to allow the first insertion part 3251 and the second insertion part 3252 to be inserted, respectively.

[0089] Further, the number of the slot 333 can also be two to match the two insertion parts 325. As shown in Figure 12 , the two slots 333 can be symmetrically and spacedly arranged on the connecting bracket 330. Among them, the two insertion parts 325 can be synchronously inserted into the two slots 333 and cooperated with the first limiting surface 334 and the second limiting surface 335 in the two slots 333, respectively, to drive the connecting bracket 330 to rotate in two opposite directions, respectively. In this way, the matching amount of the rotating member 320 and the connecting bracket 330 can be increased to improve the matching stability of the rotating member 320 and the connecting bracket 330.

[0090] Please refer to Figure 10 for more details. Figures 16-19 , Figure 16 is a partial cross-sectional structure schematic view of the rotating shaft assembly 300 along V-V, Figure 1 is a partial cross-sectional structure schematic view of the rotating shaft assembly 300 along VI-VI, Figure 17 is a partial cross-sectional structure schematic view of the rotating shaft assembly 300 along I-I, Figure 2 is a partial cross-sectional structure schematic view of the rotating shaft assembly 300 along II-II. Figure 18 is a partial cross-sectional structure schematic view of the rotating shaft assembly 300 along III-III. Figure 1 Figure 19 In some embodiments, in addition to being fixedly connected with the rotating member 320, the connecting bracket 330 is also slidably connected with the rotating member 320 and can slide when the rotating member 320 rotates. As shown in Figure 2 and

[0091] In some embodiments, in addition to being fixedly connected with the rotating member 320, the connecting bracket 330 is also slidably connected with the rotating member 320 and can slide when the rotating member 320 rotates. As shown in Figure 10 and Figures 16-17 ​As shown, when the rotating member 320 rotates from the first position to the second position, the insertion part 325 of the rotating member 320 can abut against the first limiting surface 334 and drive the connecting bracket 330 to rotate, and the insertion part 325 can slide on the first limiting surface 334 and the second limiting surface 335. When the rotating member 320 rotates from the second position to the first position, the insertion part 325 of the rotating member 320 can abut against the second limiting surface 335 and drive the connecting bracket 330 to rotate reversely, and the insertion part 325 can slide reversely on the first limiting surface 334 and the second limiting surface 335. In the embodiment, the rotating member 320 can slide relative to the connecting bracket 330 along the insertion direction X.

[0092] Further, when the rotating member 320 rotates to the first position, the insertion part 325 can also slide into the interval space 330d, and when the rotating member 320 rotates to the second position, the insertion part 325 can also slide out of the interval space 330d. In this way, the connecting rib 330c can only shield part of the area on the side of the insertion part 325 away from the second limiting surface 335, compared with the scheme that the insertion part 325 is completely shielded by the connecting bracket 330, which helps to reduce the weight of the connecting bracket 330 and reduce the manufacturing cost of the connecting bracket 330. Figure 14 The scheme that the insertion part 325 is completely shielded by the connecting bracket 330 helps to reduce the weight of the connecting bracket 330 and reduce the manufacturing cost of the connecting bracket 330. In addition, since the insertion part 325 is not shielded by the connecting rib 330c when the rotating member 320 is in the second position, part of the side plate 380 of the rotating shaft assembly 300 can also protrude into the second slot 3332 to locally increase the thickness of the side plate 380, thereby improving the structural strength of the side plate 380. Details of the side plate 380 will be described later, and will not be described here.

[0093] Further, in order to realize the sliding connection between the connecting bracket 330 and the rotating member 320, the rotating shaft assembly 300 can also include a rotating member 360. As shown, Figures 18-19As shown, the rotating member 360 is rotationally connected with the base 310 and can rotate about the base 310, and the rotating member 360 is also arranged in parallel with the rotating member 320 in the direction parallel to the axis Y. The rotating axis of the rotating member 360 is parallel to the rotating axis of the rotating member 320 and can be linked with the rotating member 320, and the rotating member 360 is also slidingly connected with the connecting bracket 330. Meanwhile, the rotating member 320 can slide on the connecting bracket 330 in the first insertion direction X (hereinafter referred to as the first direction X), and the rotating member 360 can slide on the connecting bracket 330 in the second direction M, and the projections of the first direction X and the second direction M in the same plane are not parallel. In this way, when the rotating member 320 and the rotating member 360 rotate, since the rotating axes of the two are parallel and the sliding directions on the connecting bracket 330 are not parallel, the connecting bracket 330 can slide relative to the rotating member 320 and the rotating member 360 in the first direction X. In this embodiment, the number of rotating members 360 can also be two, and the two rotating members 360 can be located on opposite sides of the base 310 and cooperate with the two rotating members 320 and the two connecting brackets 330, respectively.

[0094] Further, in order to realize the rotational connection between the base 310 and the rotating member 360, the base 310 also has an arc-shaped first sliding groove 312, and part of the rotating member 360 is arranged in an arc shape and is located in the first sliding groove 312 and can slide in the first sliding groove 312, so that the rotating member 360 can rotate about the base 310. In addition, in some embodiments, the rotational connection between the rotating member 360 and the base 310 can be the same as or similar to the rotational connection between the rotating member 320 and the base 310, and only the rotating axis of the rotating member 360 needs to be parallel to the rotating axis of the rotating member 320, which is not limited in this embodiment.

[0095] Further, in order to realize the linkage between the rotating member 320 and the rotating member 360, a connecting rod 301 can be arranged between the rotating member 320 and the rotating member 360, and the rotating member 320 and the rotating member 360 can be rotationally connected with opposite ends of the connecting rod 301, so as to realize the linkage between the rotating member 320 and the rotating member 360 by the connecting rod 301 and improve the rotating stability of the rotating member 320 and the rotating member 360. In addition, in some embodiments, the connecting rod 301 can be omitted, and the rotating member 320 and the rotating member 360 can be linked only by the connecting bracket 330, which is not limited in this embodiment.

[0096] Further, in order to realize the sliding connection between the rotating member 360 and the connecting bracket 330, the connecting bracket 330 can further be provided with a second sliding groove 3301, and the rotating member 360 can be provided with a sliding part 361 located in the second sliding groove 3301. The sliding part 361 can be located in the second sliding groove 3301 and can slide in the second direction M in the second sliding groove 3301, and the sliding track of the sliding part 361 can be a straight line. In some embodiments, the second sliding groove 3301 can also be an arc-shaped sliding groove, so that the sliding track of the sliding part 361 is an arc line, and only the orthographic projection of the first direction X and the second direction M in the same plane is not parallel.

[0097] Please refer to Figure 19 Please refer to Figures 20-21 , Figure 20 is Figure 1 is a partial cross-sectional structural schematic view of the rotating shaft assembly 300 along IX-IX, Figure 21 is Figure 2 is a partial cross-sectional structural schematic view of the rotating shaft assembly 300 along IX-IX,

[0098] Further, the rotating shaft assembly 300 can further include a middle plate 370 and a side plate 380. As shown in Figures 19-21 , the middle plate 370 can be provided on the base 310 and can be used to jointly surround the first sliding groove 312 with the base 310 to realize the rotating connection between the rotating member 360 and the base 310. The side plate 380 is rotatably connected with the connecting bracket 330 and is located on the second side 332 of the connecting bracket 330, and the side plate 380 rotates relative to the connecting bracket 330 when the connecting bracket 330 moves (rotates + slides). When the rotating member 320 rotates to the first position, the side of the middle plate 370 away from the base 310 and the side of the side plate 380 away from the second side 332 are located in the same plane and jointly form a support surface 410 for supporting the display assembly 100, and the support surface 410 can be part of the aforementioned bearing surface 400. At the same time, when the rotating member 320 rotates to the second position, the side of the middle plate 370 away from the base 310 can intersect with the side of the side plate 380 away from the second side 332 and form an included angle less than 90°.

[0099] Further, in order to realize the rotating connection between the side plate 380 and the connecting bracket 330, the connecting bracket 330 can further be provided with a third sliding groove 3303, and the side plate 380 can have an arc-shaped structure located in the third sliding groove 3303 and capable of sliding in the third sliding groove 3303, so that the side plate 380 can rotate in the direction of approaching or moving away from the second side 332. In this way, the flatness of the side of the side plate 380 away from the second side 332 can be maintained, and the stacking thickness of the side plate 380 and the connecting bracket 330 can be reduced.

[0100] Further, in order to enable the side plate 380 to rotate when the connecting bracket 330 moves, the rotating piece 360 can also be in sliding connection with the side plate 380 and slide on the side plate 380 along a third direction N, and a projection of the third direction N in the same plane as the first direction X is not parallel. For example, the side plate 380 can be provided with a fourth sliding groove 381, and the rotating piece 360 can be provided with a limiting column 362 located in the fourth sliding groove 381, and the limiting column 362 can slide in the fourth sliding groove 381 along the third direction N. In this way, when the connecting bracket 330 drives the side plate 380 to slide along the first direction X, the rotating piece 360 can slide on the side plate 380 along the third direction N and drive the side plate 380 to rotate towards the second side 332 or away from the second side 332, so that the side of the side plate 380 away from the second side 332 can not only form the support surface 410 together with the side of the middle plate 370 away from the base 310, but also form an included angle with the side of the middle plate 370 away from the base 310, and the included angle is less than 90°.

[0101] Further, the number of side plates 380 can be two, and the two side plates 380 can be symmetrically arranged on opposite sides of the middle plate 370 parallel to the axis Y and respectively in rotating connection with the two connecting brackets 330. When the rotating piece 320 is in the first position, the two side plates 380 can form the aforementioned support surface 410 together with the middle plate 370. When the rotating piece 320 is in the second position, the two side plates 380 can also be enclosed together with the middle plate 370 to form the accommodation space 302, and the distance between the two side plates 380 increases in the direction close to the middle plate 370. In this way, the bending area of the display assembly 100 can be accommodated by the accommodation space 302 in the shape of a water droplet, so as to reduce the probability of excessive bending of the display assembly 100.

[0102] Please refer to Figures 4-5 Please refer to Figures 22-24 , Figure 22 is Figure 1 FIG. 5 is another partial cross-sectional structure schematic view of the shell assembly 200 and the rotating shaft assembly 300 along V-V; Figure 23 is Figure 2 FIG. 6 is another partial cross-sectional structure schematic view of the shell assembly 200 and the rotating shaft assembly 300 along VI-VI; Figure 24 is Figure 22 FIG. 7 is a structure schematic view of the shielding piece 390.

[0103] In order to be able to form part of the appearance structure of the electronic device 10 together with the first shell 210 and the second shell 220, the rotating shaft assembly 300 can further include a shielding piece 390. As shown in FIG. 7, the shielding piece 390 can be in sliding connection with the side plate 380 and slide on the side plate 380 along a fourth direction M, and a projection of the fourth direction M in the same plane as the first direction X is not parallel. For example, the side plate 380 can be provided with a fifth sliding groove 382, and the shielding piece 390 can be provided with a limiting column 392 located in the fifth sliding groove 382, and the limiting column 392 can slide in the fifth sliding groove 382 along the fourth direction M. In this way, when the connecting bracket 330 drives the side plate 380 to slide along the first direction X, the shielding piece 390 can slide on the side plate 380 along the fourth direction M and drive the side plate 380 to rotate towards the second side 332 or away from the second side 332, so that the side of the side plate 380 away from the second side 332 can not only form the support surface 410 together with the side of the middle plate 370 away from the base 310, but also form an included angle with the side of the middle plate 370 away from the base 310, and the included angle is less than 90°. Figures 4-5As shown, the shielding member 390 is arranged on the side of the base 310 away from the middle plate 370 and can shield the base 310 in the direction close to the middle plate 370. When the electronic device 10 is in the unfolded state, the first shell 210 and the second shell 220 can be spliced on the side away from the bearing surface 400 and shield the shielding member 390, and the first shell 210 and the second shell 220 can also jointly constitute part of the appearance structure of the electronic device 10, so that the hinge assembly 300 can be hidden in the electronic device 10. At the same time, when the electronic device 10 is in the folded state, the first shell 210 and the second shell 220 can also be respectively lapped on the opposite sides of the shielding member 390 parallel to the axis Y, and jointly constitute part of the appearance structure of the electronic device 10 with the shielding member 390. In this way, the airtightness of the electronic device 10 in the unfolded state and the folded state can be ensured without additional structural members, so as to avoid the internal structure of the electronic device 10 from being exposed.

[0104] Further, in order to enable the opposite sides of the shielding member 390 parallel to the axis Y to be lapped with the first shell 210 and the second shell 220, the shielding member 390 also has a certain height requirement in the direction close to the middle plate 370, which leads to the shielding member 390 often conflicts with the structure (such as the connecting part 324 of the rotating member 320) that moves in the hinge assembly 300. That is, the two regions of the shielding member 390 lapped with the first shell 210 and the second shell 220 respectively are located on the rotating path of the connecting part 324. At this time, the connecting part 324 can be thinned to avoid the shielding member 390. For example, the side of the connecting part 324 close to the shielding member 390 can also be recessed to form an avoidance groove 3241 accommodating the shielding member 390, so that the region of the connecting part 324 corresponding to the shielding member 390 can be partially thinned to avoid the shielding member 390. However, considering the reliability problem of the rotating member 320, the thickness of the connecting part 324 that can be thinned is often limited, which leads to the stacking thickness of the connecting part 324 and the shielding member 390 in the direction close to the middle plate 370 (parallel to the stacking direction H, hereinafter only referred to as the stacking direction H) cannot be further reduced, and the stacking thickness of the connecting part 324 and the shielding member 390 affects the overall stacking thickness of the hinge assembly 300, which ultimately limits the thinning design of the electronic device 10.

[0105] As Figures 22-24As shown, in order to further reduce the stack thickness of the connecting portion 324 and the shielding member 390 while ensuring a reliable thickness for the connecting portion 324, the shielding member 390 may include: a main body portion 391 located on the side of the base 310 opposite to the middle plate 370 and connected to the base 310, and two movable portions 392 respectively movably connected to the main body portion 391, wherein the movable portions 392 can cooperate with the main body portion 391 to form a shielding surface 3902. The movable portions 392 can retract relative to the main body portion 391 to create clearance space to avoid the connecting portion 324. This configuration not only achieves the original shielding function of the shielding member 390, but also allows the movable portions 392 to avoid the connecting portion 324, enabling the movable portions 392 and the connecting portion 324 to be stacked more compactly, thereby reducing the stack thickness of the connecting portion 324 and the shielding member 390. Of course, in some embodiments, the thickness of the connecting portion 324 can be locally increased by utilizing the clearance space formed by the movement of the movable portion 392, thereby improving the structural strength of the rotating member 320.

[0106] Specifically, the rotating shaft assembly 300 may include: a moving component 303 rotatably connected to the base 310. Figure 7 (As shown), the moving member 303 is capable of rotating around the base 310 between a first position and a second position. Two movable parts 392 are respectively located on the rotation paths of the two moving members 303. When the moving member 303 rotates to the first position, the movable part 392 is pushed by the moving member 303 to retract and avoid the rotation of the moving member 303. When the moving member 303 rotates to the second position, the movable part 392 can return to its original position. In this embodiment, the moving member 303 may include at least one of a rotating member 320 and a rotating member 360; the rotating member 320 will be used as an example for explanation below.

[0107] Further, the two movable portions 392 are also located on the rotation paths of the connecting portions 324 of the two rotating members 320. The main body portion 391 and the two movable portions 392 can collectively surround the mounting space 3901, and the base 310 can be arranged in the mounting space 3901 to shield the base 310 and part of the rotating member 320 (the sleeve portion 323) by using the mounting space 3901, and the connecting portions 324 can be arranged to protrude out of the mounting space 3901. At the same time, when the rotating member 320 rotates to the first position, the two movable portions 392 can be pushed by the two connecting portions 324 to move to avoid the rotation of the connecting portions 324. When the rotating member 320 rotates to the second position, the two movable portions 392 can also be reset, and the areas of the two movable portions 392 pushed by the connecting portions 324 can also be respectively overlapped with the first shell 210 and the second shell 220, so that the first shell 210, the second shell 220, the main body portion 391 and the two movable portions 392 can collectively constitute part of the appearance structure of the electronic device 10. In this way, the movable portion 392 can move to avoid the connecting portion 324, so that the connecting portion 324 can be arranged closer to the movable portion 392 to reduce the stacking thickness of the shielding member 390 and the connecting portion 324 in the stacking direction H.

[0108] It can be understood that the above embodiment is only an exemplary description of the shielding member 390 applied to the electronic device 10 (foldable mobile phone), and the shielding member 390 can also be applied to other devices with similar requirements as the foldable mobile phone. At this time, the movable portion 392 can also be driven by other external structures similar to the rotating member 320 and / or the rotating member 360 to avoid the movement of the external structure.

[0109] Please refer to Figures 22-23 Please refer to Figures 25-27 , Figure 25 is Figure 24 is an exploded structural schematic view of the shielding member 390 in Figure 26 is Figure 25 is a partial enlarged view of A in Figure 27 is Figure 22 is a connection structure schematic view of the base 310, the rotating shaft 340 and part of the shielding member 390 in

[0110] Further, the movable portion 392 can be rotationally connected with the main body portion 391 to avoid or reset the rotation of the connecting portion 324 by rotation. As Figures 22-26As shown, the main body 391 can include a fixing portion 3911 arranged on the base 310 away from the middle plate 370 and connected with the base 310, and two limiting portions 3912 respectively connected with opposite ends of the fixing portion 3911. The two movable portions 392 can be respectively arranged on opposite sides of the fixing portion 3911 parallel to the axis Y and located between the two limiting portions 3912, and opposite ends of the movable portion 392 are respectively rotationally connected with the two limiting portions 3912, so as to limit the movable portion 392 in the direction parallel to the axis Y while rotationally connecting the movable portion 392 with the main body 391.

[0111] Further, the fixing portion 3911, the two limiting portions 3912 and the two movable portions 392 can collectively form the mounting space 3901, and the fixing portion 3911, the limiting portions 3912 and the two movable portions 392 collectively form a shielding surface 3902 away from the mounting space 3901. The orthographic projection of the base 310 and part of the rotating member 320 (the sleeve portion 323) in the direction close to the fixing portion 3911 can be located in the shielding surface 3902, so as to shield the base 310 and the sleeve portion 323 by the shielding surface 3902. At the same time, since the movable portion 392 avoids the rotation of the connecting portion 324 by rotation, the area of the shielding surface 3902 changes correspondingly with the rotation position of the movable portion 392. That is, when the rotating member 320 is located at the first position, that is, the movable portion 392 rotates to avoid the connecting portion 324, the area of the shielding surface 3902 is the smallest. When the rotating member 320 is located at the second position, that is, the movable portion 392 rotates to reset, the area of the shielding surface 3902 is the largest. In this way, the continuity of the shielding surface 3902 can be ensured to avoid the gap between the movable portion 392 and the fixing portion 3911.

[0112] Further, the rotation axis of the movable portion 392 can overlap with the rotation axis of the rotating member 320, so as to improve the rotation consistency of the movable portion 392 and the rotating member 320. As shown in the figure, Figures 26-27As shown, the limiting portion 3912 can be provided with a guide groove 3913 on the side facing the movable portion 392, and the movable portion 392 can be provided with a sliding block 3921 located in the guide groove 3913. The guide groove 3913 can be an arc-shaped groove, and the sliding block 3921 can also be arranged in an arc shape and can slide in the guide groove 3913, so that the sliding track of the sliding block 3921 can be an arc, so as to realize the rotary connection of the movable portion 392 and the limiting portion 3912. At the same time, the movable portion 392 is also sleeved on the rotating shaft 340 and is rotatably connected with the rotating shaft 340, so that the rotation axis of the movable portion 392 can overlap with the rotation axis of the rotating member 320. For example, the movable portion 392 has a matching structure 3922 protruding into the mounting space 3901, and the matching structure 3922 can be arranged opposite to the base 310 in the rotation axis of the rotating member 320, so that the opposite ends of the rotating shaft 340 can be connected (inserted) with the base 310 and the matching structure 3922 respectively. In this embodiment, the limiting portion 3912 is provided with two guide grooves 3913 to rotatably connect with the two movable portions 392 respectively, and the two guide grooves 3913 are located on opposite sides of the fixed portion 3911.

[0113] Further, since the movable portion 392 is sleeved on the rotating shaft 340, the rotating shaft 340 can also limit the movable portion 392. At this time, the guide groove 3913 can also penetrate through the side of the limiting portion 3912 away from the mounting space 3901 to form a slot 3914 for the movable portion 392 to be loaded or unloaded. In this way, not only the assembly convenience of the limiting portion 3912 and the movable portion 392 can be improved, but also the stacking thickness of the limiting portion 3912 and the movable portion 392 in the stacking direction H can be reduced. Of course, in some embodiments, in addition to limiting the movable portion 392 by the rotating shaft 340, other structures such as a stop position can also be used to limit the movable portion 392, which will not be described one by one in this embodiment.

[0114] In some embodiments, the rotation axis of the movable portion 392 can also be parallel to the rotation axis of the rotating member 320 in addition to overlapping with the rotation axis of the rotating member 320. At this time, the guide groove 3913 can also not penetrate through the side of the limiting portion 3912 away from the mounting space 3901 to limit the movable portion 392, and only the movable portion 392 can rotate to avoid or reset, which is not limited in this embodiment.

[0115] In some embodiments, the positions of the guide slot 3913 and the sliding block 3921 can also be interchanged. That is, the movable part 392 is provided with the aforementioned guide slot 3913, and the limiting part 3912 is provided with the aforementioned sliding block 3921. In addition, in some embodiments, the movable part 392 and the rotating member 320 can also be rotationally connected in other ways. For example, the limiting part 3912 can be provided with a protruding shaft near the side of the movable part 392, and the movable part 392 can be provided with a recess near the side of the limiting part 3912, and the protruding shaft can be arranged in the recess and can rotate in the recess to achieve the rotational connection between the limiting part 3912 and the movable part 392.

[0116] Further, when the rotating member 320 is rotated to the second position, the movable part 392 can also be reset under the push of the rotating member 320. As shown in Figures 22-23 Further, when the rotating member 320 is rotated to the second position, the movable part 392 can also be reset under the push of the rotating member 320. As shown in

[0117] Further, when the rotating member 320 is rotated to the second position, the movable part 392 can also be reset under the push of the rotating member 320. As shown in

[0118] In some embodiments, the first shell 210 and the second shell 220 can further be provided with a wear-resistant part 201 on the region where the first shell 210 and the second shell 220 are overlapped with the first contact part 3923, and the wear-resistant part 201 can abut against the first contact part 3923 to shield the gap between the first shell 210 and the second shell 220 and the first contact part 3923. In the present embodiment, the wear-resistant part 201 can be a part of the first shell 210 and the second shell 220 that is protruded, or can be a wear-resistant structure that is embedded or welded on the first shell 210 and the second shell 220, and the present embodiment is not limited in this regard.

[0119] Please refer to Figure 22 and Figure 23 Please refer to Figures 28-30 , Figure 28 is Figure 1 is another partial cross-sectional structure diagram of the transfer shaft assembly 300 along I-I, Figure 29 is Figure 24 is a partial cross-sectional structure diagram of the shielding part 390 along XI-XI, Figure 30 is a structure diagram of the shielding part 390 in some embodiments.

[0120] In some embodiments, the movable part 392 can be rotated under the pushing of the connecting part 324, and the movable part 392 can also be rotated under the pushing of the rotating part 360. As shown in Figure 22 , Figure 23 and Figure 28 , the rotating part 360 has a connecting arm 363, and the connecting arm 363 can be connected to the region where the rotating part 360 and the base 310 are rotationally connected, and the region where the rotating part 360 and the connecting support 330 are slidingly connected. The movable part 392 can be located on the rotating path of the connecting arm 363, and when the rotating part 320 is rotated to the first position, the rotating part 360 is linked with the rotating part 320 (equivalent to the rotating part 360 is also rotated to the first position), so that the connecting arm 363 can push the movable part 392 to rotate, so as to realize the avoidance of the movable part 392 to the connecting arm 363 and the connecting part 324.

[0121] Further, since the rotating member 360 is rotatably connected to the base 310 in a virtual shaft manner, i.e., the rotating member 360 is rotatably connected to the base 310 by cooperating with the arc-shaped first sliding groove 312, when the rotating member 320 is rotated to the first position, i.e., the rotating member 360 is rotated to the first position, the reset of the movable part 392 can be achieved by the sleeve part 323 of the rotating member 320 pushing, and the rotating member 360 does not participate in the reset of the movable part 392. Of course, in some embodiments, when the rotating member 360 is also rotatably connected to the base 310 by the rotating shaft 340, the rotating member 360 can also have a structure similar to the sleeve part 323 of the rotating member 320, so that the rotating member 360 can also use the structure to push the movable part 392 to reset.

[0122] In some embodiments, the movable part 392 can also be rotated under the joint pushing of the connecting part 324 (rotating member 320) and the rotating member 360. At this time, the moving member 303 can simultaneously include the rotating member 320 and the rotating member 360, and the rotating member 320 and the rotating member 360 are linked. Among them, the rotating member 320 and the rotating member 360 are located on the same side of the base 310 and are rotatably connected to the base 310, and can rotate between the first position and the second position. The movable part 392 can be located on the rotating path of the rotating member 320 (connecting part 324) and the rotating member 360 at the same time. When the rotating member 320 and the rotating member 360 are rotated to the first position, the movable part 392 can be rotated under the pushing of the rotating member 320 and the rotating member 360 to avoid the rotation of the rotating member 320 and the rotating member 360. Similarly, when the rotating member 320 and the rotating member 360 are rotated to the second position, the movable part 392 can be reset under the pushing of the sleeve part 323 of the rotating member 320. In this embodiment, the two moving members 303 are equivalent to two groups of rotating members 320 and rotating members 360, and the two groups of rotating members 320 and rotating members 360 are located on opposite sides of the base 310.

[0123] It can be understood that the above-mentioned embodiments are only exemplary descriptions of the rotating shaft assembly 300 for surrounding to form the water drop-shaped containing space 302, and at this time the moving member 303 can include at least one of the rotating member 320 and the rotating member 360. In some embodiments, when the rotating shaft assembly 300 does not have the need to surround to form the water drop-shaped containing space 302, the moving member 303 can not be limited to the rotating member 320 and / or the rotating member 360, and the specific structure of the moving member 303 can be adaptively adjusted according to the design requirements, as long as the moving member 303 can be rotatably connected to the base 310 and the rotating shaft assembly 300 can drive the first shell 210 and the second shell 220 to fold along the axis Y, which is not limited in this embodiment.

[0124] In some embodiments, the movable part 392 can be reset in other ways besides being pushed by the sleeve part 323. As shown in FIG. 13A, the guide groove 3913 can be filled with an elastic structure 393 (such as a silica gel body, a rubber body, a spring, or a spring sheet, etc.). When the rotating piece 320 is turned to the first position, the slider 3921 of the movable part 392 can slide in the guide groove 3913 under the push of the connecting part 324, and press the elastic structure 393 to be elastically deformed. When the rotating piece 320 is turned to the second position, the movable part 392 can be reset under the elastic force generated by the elastic structure 393. In addition, the connecting part 324 can also limit the movable part 392 to avoid the movable part 392 from being pulled out of the guide groove 3913 under the elastic action of the elastic structure 393. Figure 29

[0125] In some embodiments, the movable part 392 can avoid the rotating piece 320 by linear sliding besides rotating to avoid the rotating piece 320. As shown in FIG. 13B, the fixed part 3911 can be provided with a mounting groove 3915 on the side close to the base 310, and the movable part 392 can be arranged in the mounting groove 3915, and the elastic structure 393 is arranged between the movable part 392 and the bottom wall of the mounting groove 3915. When the rotating piece 320 is turned to the first position, the movable part 392 can slide into the mounting groove 3915 under the push of the rotating piece 320, and press the elastic structure 393 to be elastically deformed. When the rotating piece 320 is turned to the second position, the movable part 392 can be reset under the elastic force of the elastic structure 393. In this way, the movable part 392 can also avoid the rotating piece 320 by linear sliding. It can be understood that the sliding cooperation mode of the movable part 392 and the fixed part 3911 is only illustrative, and in other embodiments, the movable part 392 and the fixed part 3911 can also realize linear sliding by other sliding modes, which are not limited in the present embodiment.
