[0003] A folding electronic device generally includes a flexible screen and a screen supporting assembly for supporting the flexible screen. The screen supporting assembly includes a fixed shaft, and the position of the flexible screen relative to the fixed shaft can be folded when the folding electronic device is folded. In the existing folding electronic device, the edge of the flexible screen relative to the fixed shaft region is generally open outward, which can affect the appearance effect of the folding electronic device, and the flexible screen is easily damaged by collision and other problems during use, thereby reducing the reliability of the folding electronic device. SUMMARY

[0004] Embodiments of the present application provide an electronic device, a protection mechanism and a rotating mechanism to improve the problem that the flexible screen of the electronic device is damaged by collision in the related art.

[0005] To achieve the above-mentioned purpose, the embodiments of the present application provide the following solutions:

[0006] In one aspect, an electronic device is provided, including a flexible screen, a rotating mechanism and a protection mechanism. At least part of the rotating mechanism is located on the non-display side of the flexible screen, and is used to realize the folding of the flexible screen. The rotating mechanism includes a main shaft, and the side of the main shaft facing the flexible screen has a recessed portion and a protruding portion. The protection mechanism includes a connecting and fixing member and a protection member. The protection member covers part of the edge of the flexible screen. The fixing member is installed in the recessed portion, and the fixing member is also connected with the protruding portion. In a first direction, at least part of the fixing member is located between the flexible screen and the protruding portion. The first direction is the extension direction of the main shaft.

[0007] In summary, the fixing member is connected with the recessed portion and the protruding portion respectively, which is conducive to increasing the connection area of the fixing member and the main shaft, and further conducive to improving the connection reliability between the fixing member and the main shaft. At the same time, in the first direction, the flexible screen is located on the first side of the fixing member, and at least part of the protruding portion is located on the second side of the fixing member. When the electronic device falls, the protruding portion can also play a protective role for the fixing member.

[0008] In some embodiments, the fixing member is bonded with the side wall of the recess, and the fixing member is bonded with the side wall of the protrusion. Through the above arrangement, the fixing member is bonded with the recess and the protrusion respectively, which is conducive to increasing the bonding area of the fixing member and the main shaft, and further conducive to improving the connection reliability between the fixing member and the main shaft.

[0009] In some embodiments, the side wall of the protrusion is coplanar with the side wall of the recess. In the process of installing the fixing member on the main shaft, glue can be arranged in the recess, and the first end of the body portion is installed in the recess to bond the fixing member with the recess. Since the side wall of the protrusion is in the same plane as the side wall of the recess, the glue in the recess can be extruded onto the side wall of the protrusion to bond the fixing member with the protrusion.

[0010] In some embodiments, the protrusion includes a first protrusion and a second protrusion, the first protrusion is located on one side of the fixing member along a first direction, and the number of the second protrusion is two, the fixing member is located between the two second protrusions along a second direction, the second direction intersects the first direction, and the second direction also intersects the thickness direction of the main shaft.

Through the above arrangement, it is conducive to further increasing the connection area of the fixing member and the protrusion, and further conducive to improving the connection reliability between the fixing member and the main shaft.

[0013] In some embodiments, in the thickness direction of the main shaft, at least part of the protrusion is higher than part of the flexible screen. Through the above arrangement, the protrusion can play a protective role for the bending area of the flexible screen. At the same time, since the height of the protrusion in the third direction is increased, it is also conducive to further increasing the connection area of the fixing member and the protrusion, and further conducive to improving the connection reliability between the fixing member and the main shaft.

The partial protruding portion is located in the groove. Through the above arrangement, the partial protruding portion can also be embedded in the fixing member, which is conducive to further increasing the connection reliability between the fixing member and the main shaft.

[0016] In some embodiments, the partial protruding portion is also bonded in the groove. Through the above arrangement, it is conducive to further increasing the connection area of the fixing member and the protruding portion, and thus conducive to improving the connection reliability between the fixing member and the main shaft.

Through the above arrangement, when the electronic device falls, the stop portion is easily affected by the impact force, and the second end of the stop portion is not easily broken under the action of the impact force, which is conducive to improving the reliability of the fixing member.

[0018] In some embodiments, the stop portion includes a first force receiving surface and a first matching surface, the first force receiving surface and the first matching surface are arranged along the first direction, the first force receiving surface is reused as a groove wall of the groove, in the thickness direction of the main shaft, the first end of the first force receiving surface is closer to the first end of the body portion than the second end of the first force receiving surface, and in the first direction, the distance between the first end of the first force receiving surface and the first matching surface is less than the distance between the second end of the first force receiving surface and the first matching surface.

Through the above arrangement, in the first direction, the size of the first end of the stop portion can be less than the size of the second end of the stop portion.

[0021] In some embodiments, the first force receiving surface and the second force receiving surface are both planar.

[0067] In order to facilitate understanding of the electronic device 1 provided by the embodiments of the present application, the following introduces an electronic device 1 in combination with FIG. 1 and FIG. 2 as follows:

[0068] As shown in FIG. 1 and FIG. 2, the electronic device 1 includes a flexible screen 30. The flexible screen 30 can be an active matrix organic light emitting diode (AMOLED) display screen.

[0069] The AMOLED display screen is a self-luminous display screen, and does not need to be provided with a back light module (BLM). Therefore, when a substrate substrate in the AMOLED display screen is made of a flexible resin material, for example, polyethylene terephthalate (PET), the AMOLED display screen can have a bendable characteristic.

[0070] In addition, as shown in FIG. 1 and FIG. 2, the electronic device 1 further comprises a rotating mechanism 10 for carrying the flexible screen 30. At least part of the rotating mechanism 10 is located on the non-display side of the flexible screen 30, for realizing the folding of the flexible screen. For example, the flexible screen 30 can comprise a first fixed area 31, a bending area 32 and a second fixed area 33 connected in sequence, and the rotating mechanism 10 can be stacked with the bending area 32 of the flexible screen 30.

[0071] The rotating mechanism 10 comprises a main shaft 11, a first rotating shaft assembly 12 and a second rotating shaft assembly 13. The first rotating shaft assembly 12 and the second rotating shaft assembly 13 are respectively located on both sides of the main shaft 11, and the first rotating shaft assembly 12 and the second rotating shaft assembly 13 are respectively rotationally connected with the main shaft 11, so that the first rotating shaft assembly 12 and the second rotating shaft assembly 13 can respectively rotate relative to the main shaft 11. The embodiments of the present application only briefly illustrate part of the structure of the first rotating shaft assembly 12 and the second rotating shaft assembly 13, and the drawings are also simplified, and the embodiments of the present application do not strictly limit the specific structure of the first rotating shaft assembly 12 and the second rotating shaft assembly 13.

[0072] Hereinafter, the extension direction of the main shaft 11 is referred to as the first direction X, the arrangement direction of the first rotating shaft assembly 12 and the second rotating shaft assembly 13 is referred to as the second direction Y, and the thickness direction of the main shaft 11 is referred to as the third direction Z.

[0073] The second direction Y can intersect the first direction X, and the second direction Y can also intersect the third direction Z. For example, the second direction Y can be perpendicular to the first direction X, and the second direction Y can also be perpendicular to the third direction Z.

[0074] The electronic device 1 further comprises a first structural member 21 for carrying the first fixed area 31 of the flexible screen 30, and a second structural member 22 for carrying the second fixed area 33 of the flexible screen 30. The first structural member 21 and the second structural member 22 are connected to both sides of the rotating mechanism 10, the first structural member 21 is connected with the first rotating shaft assembly 12, and the second structural member 22 is connected with the second rotating shaft assembly 13. The first structural member 21 and the second structural member 22 are used to carry the flexible screen 30, so that the flexible screen 30 can be kept as flat as possible during use, and the non-display surface of the flexible screen 30 is protected.

[0075] The first structural member 21 can rotate relative to the rotating mechanism 10 through the first rotating shaft assembly 12, and the second structural member 22 can rotate relative to the rotating mechanism 10 through the second rotating shaft assembly 13. The embodiments of the present application only briefly illustrate part of the structure of the first structural member 21 and the second structural member 22, and the drawings are also simplified, and the embodiments of the present application do not strictly limit the specific structure of the first structural member 21 and the second structural member 22.

[0076] The first structural member 21 and the second structural member 22 can each include a middle frame structure for mounting and fixing other components of the electronic device 1. For example, a camera, an earphone, a receiver, a key, a battery, and the like. The embodiments of the present application do not limit other electronic elements disposed on the first structural member 21 and the second structural member 22. The first structural member 21 and the second structural member 22 can each further include a decorative cover plate for protecting devices inside the middle frame structure and for presenting part of the appearance of the electronic device 1.

[0077] For example, the first fixed area 31 of the flexible screen 30 can be fixed to the first structural member 21 by a glue layer 40, the second fixed area 33 can be fixed to the second structural member 22 by a glue layer, and the bending area 32 of the flexible screen 30 can be fixed to the rotating mechanism 10. The glue layer can be a thin film layer formed after glue is applied. The embodiments of the present application do not limit the specific form of the glue layer. For example, the glue layer can be an intermittent thin film layer, or the glue layer can also be an integral thin film layer.

[0078] When the first structural member 21 and the second structural member 22 are in the unfolded state, the included angle between the first structural member 21 and the second structural member 22 can be substantially 180° (it can be understood that the included angle between the first structural member 21 and the second structural member 22 also allows a small deviation, for example, the included angle can be 165°, 177°, or 185°). At this time, the flexible screen 30 is also in the unfolded state, that is, the electronic device 1 is in the unfolded state.

[0079] When the first structural member 21 and the second structural member 22 are in the folded state, the included angle between the first structural member 21 and the second structural member 22 can be substantially 0° (it can be understood that the included angle between the first structural member 21 and the second structural member 22 also allows a small deviation, for example, the included angle can be 1°, 3°, or 5°). At this time, the flexible screen 30 is also in the folded state, that is, the electronic device 1 is in the folded state.

[0080] In order to shield and protect the edge of the flexible screen 30, the first structural member 21 is provided with a first frame 41. Part of the first frame 41 can be disposed between the edge of the first structural member 21 and the flexible screen 30. Referring to FIGS. 3 and 4, in the thickness direction of the flexible screen 30, the first frame 41 covers part of the edge of the flexible screen 30, and the first frame 41 and the flexible screen 30 can have a first gap P1 therebetween. The second structural member 22 is provided with a second frame 42. Part of the second frame 42 can be disposed between the edge of the second structural member 22 and the flexible screen 30, and in the thickness direction of the flexible screen 30, the second frame 42 covers part of the edge of the flexible screen 30, and the second frame 42 and the flexible screen 30 can have a second gap P2 therebetween.

[0081] Through the above arrangement, the first frame 41 can shield and protect the edge of the first fixed area 31 of the flexible screen 30, and the second frame 42 can shield and protect the edge of the second fixed area 33 of the flexible screen 30, so as to reduce the damage of the edge of the flexible screen 30 and improve the appearance effect.

[0082] Further, the electronic device 1 can further include a protection mechanism 50 to shield and protect the edge of the bending area 32 of the flexible screen 30, so as to reduce the entry of dust, water and other external foreign matters into the inside of the flexible screen 30, and also make the edge position of the bending area 32 of the flexible screen 30 more beautiful. For example, the two ends of the rotating mechanism 10 can be respectively provided with a protection mechanism 50.

[0083] In the embodiment of the present application, as shown in FIG. 5 and FIG. 12, the protection mechanism 50 includes a fixing member 51, a protection member 52 and a supporting part 513, which can be connected between the fixing member 51 and the protection member 52.

[0084] The fixing member 51 is installed on the main shaft 11 of the rotating mechanism 10, and the protection member 52 covers part of the edge of the flexible screen 30. For example, in the thickness direction of the flexible screen 30, the orthographic projection of the protection member 52 on the flexible screen 30 covers the edge of the bending area 32 of the flexible screen 30, so as to protect the flexible screen 30 when the device is bent.

[0085] In addition, in the thickness direction of the flexible screen 30, the first frame 41, one end of the protection member 52 and the flexible screen 30 can be sequentially stacked, and the one end of the protection member 52 can be located in the first gap P1; in the thickness direction of the flexible screen 30, the second frame 42, the other end of the protection member 52 and the flexible screen 30 can be sequentially stacked, and the other end of the protection member 52 is located in the second gap P2. So that the first frame 41 and the second frame 42 can play a certain fixed role for the protection member 52.

[0086] Further, as shown in FIG. 5, one end of the protection member 52 can be provided with a first lug part 521, and the other end of the protection member 52 can be provided with a second lug part 522. The first lug part 521 can extend to between the flexible screen 30 and the first structural member 21 along the third direction Z, and specifically, the first lug part 521 can also be located between the flexible screen 30 and the first frame 41. The second lug part 522 can extend to between the flexible screen 30 and the second structural member 22 along the third direction Z, and specifically, the second lug part 522 can also be located between the flexible screen 30 and the second frame 42. Through the above arrangement, the flexible screen 30, the first structural member 21 and the second structural member 22 can further play a fixed role for the protection member 52.

[0087] In addition, as shown in FIG. 3, in some examples, there can be a gap between the guard 52 and the first structural member 21 in the first direction X, and there can also be a gap between the guard 52 and the second structural member 22. The electronic device can also have two protrusions, one of which fills the gap between the guard 52 and the first structural member 21, and the other of which fills the gap between the guard 52 and the second structural member 22. One of the protrusions can be integrally formed with the first structural member 21, and the other protrusion can be integrally formed with the second structural member 22. With the above arrangement, external foreign matter such as dust and water can be prevented from entering the interior of the electronic device.

[0088] In the embodiments of the present application, the strength of the fixing member 51 is greater than the strength of the guard 52, and the guard 52 can be an elastically deformable member.

[0089] In some embodiments, the fixing member 51 can be a metal member formed of a metal material and has a relatively large strength. Specifically, the metal material forming the fixing member 51 can be various types of metal materials or alloy materials such as stainless steel, cast iron, aluminum, etc. It can be understood that in other embodiments of the present application, the fixing member 51 can also be a structural member formed of other types of materials. For example, in some embodiments, the fixing member 51 can be a fine ceramic member formed of a fine ceramic material.

[0090] For example, the fixing member 51 can be obtained by metal injection molding (MIM), and the fixing member can be referred to as a MIM member. In the present embodiment, the fixing member 51 obtained by metal injection molding has a relatively high dimensional accuracy, thereby facilitating the cooperation between the guard mechanism 50 and the main shaft 11. In addition, the fixing member 51 obtained by metal injection molding has uniform microstructure and high relative density at each position of the body portion 511, thereby having a relatively high strength, and thus can achieve a better protection effect on the edge of the flexible screen 30. In addition, the surface of the body portion 511 has a good surface finish, so that the electronic device 1 can have a good appearance effect.

[0091] Alternatively, in some other embodiments, the fixing member 51 can also be formed by other processes, for example, by Computer numerical control (CNC) machining, die casting, etc.

[0092] In some embodiments, the surface of the fixing member 51 can be coated with a plating layer to further improve the appearance of the protection mechanism 50. For example, in some embodiments, the plating layer on the surface of the fixing member 51 has the same color as the back shell of the electronic device 1, so that the appearance color of the electronic device 1 is uniform, thereby having a better appearance effect. In some embodiments, the plating layer can also block the corrosion of water, oxygen and the like from the outside to the fixing member 51, thereby improving the quality of the electronic device 1.

[0093] The plating layer can be formed by evaporation, vapor deposition or other methods, and the forming method of the plating layer is not limited herein.

[0094] In some embodiments, the protection member 52 is an elastically deformable member, and the protection member 52 has a small strength and can be bent and deformed. For example, as shown in FIGS. 6 and 7, during the conversion of the electronic device 1 from a flat state to a folded state, the two ends of the protection member 52 can be rotated towards each other to bend and deform the protection member 52.

[0095] In some embodiments of the present application, the protection member 52 is made of a soft gel material that can be elastically deformed. Specifically, the soft gel material forming the protection member 52 can be silicone, thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer rubber (TPU), polyvinyl chloride (PVC) soft gel, rubber (such as silicone rubber, natural rubber, butadiene rubber, styrene butadiene rubber, isoprene rubber, etc.) and the like. It can be understood that the protection member 52 of the present application can also be formed of other materials that can be elastically deformed, which are not listed one by one herein.

[0096] Referring to FIGS. 5, 8 and 9, FIGS. 8 and 9 are structure diagrams of the main shaft from two viewing angles. In some embodiments, the main shaft 11 is provided with a recess 111 on the side facing the flexible screen 30. The recess 111 can be substantially a rectangular groove. Correspondingly, the fixing member 51 can be substantially a columnar structure, and one end of the fixing member 51 can be bonded in the recess 111. Through the above arrangement, the protection mechanism 50 is fixed on the main shaft 11.

[0097] However, with the improvement of the thinness of the folding electronic device 1, the thickness of the main shaft 11 is also thinned, the depth of the recess 111 is limited, the connection area between the recess 111 and the fixing member 51 is small, and the fixing member 51 can shake or tilt relative to the main shaft 11, resulting in poor reliability of the connection between the fixing member 51 and the main shaft 11.

[0098] Therefore, in the embodiments of the present application, referring to FIG. 8 and FIG. 9, the main shaft 11 further has a protruding portion 112 on the side facing the flexible screen 30, and the fixing member 51 is further connected with the protruding portion 112.

[0099] For example, the side of the main shaft 11 facing the flexible screen 30 can have a supporting surface 113, at least part of the supporting surface 113 can be arranged relative to the flexible screen 30, and the supporting surface 113 can be used to support the bending area 32 of the flexible screen 30, so as to improve the flatness of the flexible screen 30 in the flat state. Here, the "supporting surface 113" can be understood as a plane or an approximately plane, wherein the plane can be a surface parallel to the first direction X and the second direction Y, and the approximately plane can be a surface with slight ups and downs, and the acceptable deviation range of the approximately plane can be, for example, a deviation within 5%.

[0100] The recessed portion 111 and the protruding portion 112 can be arranged on the supporting surface 113. For example, the recessed portion 111 can be recessed from the supporting surface 113 in the direction away from the flexible screen 30, and the protruding portion 112 can be protruded from the supporting surface 113 in the direction close to the flexible screen 30.

[0101] Further, the main shaft 11 can be an integrally formed structure. For example, the recessed portion 111 of the main shaft 11 and the protruding portion 112 of the main shaft 11 can be formed by injection molding. Alternatively, in some other embodiments, the protruding portion 112 can also be connected to the main shaft body by bonding, welding or the like, so as to form the main shaft 11.

[0102] Referring to FIG. 10, FIG. 11 and FIG. 12, in some embodiments, the fixing member 51 can include a body portion 511.

[0103] Referring to FIG. 13 and FIG. 14, the first end 511A of the body portion and the second end 511B of the body portion can be arranged along the third direction Z. Referring to FIG. 15, which is a sectional view of the protection mechanism in FIG. 6 along the A-A sectional line, the first end 511A of the body portion is closer to the main shaft 11 than the second end 511B of the body portion. Further, the first end 511A of the body portion can be installed in the recessed portion 111, so that the fixing member 51 is connected with the recessed portion 111. For example, the first end 511A of the body portion can be snap-fit connected, bonded or welded together with the recessed portion 111.

[0104] Referring to FIG. 15, in some embodiments, the second end 511B of the body portion can also cover at least part of the protruding portion 112. For example, the second end 511B of the body portion can be substantially in the form of a plate. Through the above arrangement, in the third direction Z, the second end 511B of the body portion can shield part of the protruding portion 112, which is conducive to further improving the aesthetic appearance of the electronic device in the visual angle along the third direction Z.

[0105] In addition, with continuous reference to Fig. 15, in the first direction X, at least part of the fixing member 51 is located between the flexible screen 30 and the protruding portion 112. Specifically, the body portion 511 of the fixing member 51 can be located between the flexible screen and the protruding portion. The body portion 511 can also be connected with the protruding portion 112, so that the fixing member 51 is connected with the protruding portion 112. Compared with the fixing member 51 being connected with only the recessed portion 111, the fixing member 51 being connected with both the recessed portion 111 and the protruding portion 112 is beneficial to increase the connection area of the fixing member 51 with the main shaft 11, and further beneficial to improve the connection reliability between the fixing member 51 and the main shaft 11.

[0106] For example, the flexible screen 30, the recessed portion 111 and at least part of the protruding portion 112 can be arranged in the first direction X in sequence, and at least part of the protruding portion 112 is closer to the outer edge of the main shaft 11 than the recessed portion 111.

[0107] Through the above arrangement, in the first direction X, at least part of the fixing member 51 is located between the flexible screen 30 and the protruding portion 112, and further, the body portion 511 is located between the flexible screen 30 and the protruding portion 112. When the electronic device 1 falls, the protruding portion 112 can also play a protective role on the fixing member 51.

[0108] Further, in the embodiment in which the main shaft 11 is an integral structure, it is beneficial to further improve the connection reliability between the fixing member 51 and the main shaft 11.

[0109] In summary, the fixing member 51 is connected with both the recessed portion 111 and the protruding portion 112, which is beneficial to increase the connection area of the fixing member 51 with the main shaft 11, and further beneficial to improve the connection reliability between the fixing member 51 and the main shaft 11. At the same time, since in the first direction X, at least part of the fixing member 51 is located between the flexible screen 30 and the protruding portion 112, when the electronic device 1 falls, the protruding portion 112 can also play a protective role on the fixing member 51.

[0110] In addition, in some embodiments of the present application, with continuous reference to Fig. 15, in the first direction X, there is a certain gap between the edge of the bending area 32 of the flexible screen 30 and the fixing member 51. When the electronic device 1 is subjected to impact, the impact force acting on the fixing member 51 is not easy to be conducted to the flexible screen 30 to damage the flexible screen 30, further improving the reliability of the electronic device 1.

[0111] The present application does not limit the connection mode between the fixing member 51 and the protruding portion 112. For example, in some embodiments, the fixing member 51 can be connected with the protruding portion 112 through clamping connection, fastener connection or welding.

[0112] Alternatively, in some embodiments, the fixing member 51 is bonded to the side wall of the recess 111, and the fixing member 51 is bonded to the side wall of the protrusion 112. Specifically, the body part 511 of the fixing member 51 can be bonded to the side wall of the protrusion 112, and the side wall of the protrusion 112 can be the side wall facing the fixing member 51.

[0113] For example, the electronic device 1 can include glue. Specifically, part of the glue can be arranged on the bottom wall and the side wall of the recess 111, so that the part of the glue can connect the recess 111 and the fixing member 51. In addition, part of the glue can be arranged on the side wall of the protrusion 112 facing the recess 111, so that the part of the glue can connect the protrusion 112 and the fixing member 51.

[0114] Through the above arrangement, the fixing member 51 is bonded to the recess 111 and the protrusion 112 at the same time, which is conducive to increasing the bonding area of the fixing member 51 and the main shaft 11, and further conducive to improving the connection reliability between the fixing member 51 and the main shaft 11.

[0115] FIG. 16 is a sectional view of the main shaft in FIG. 6 along the A-A sectional line. Further, referring to FIGS. 8, 9, 15 and 16, the side wall of the protrusion 112 can be coplanar with the side wall of the recess 111. Specifically, the recess 111 can be a substantially rectangular groove, and the recess 111 can include a first side wall 111a facing away from the flexible screen 30 along the first direction X, and a second side wall 111b and a third side wall 111c arranged along the second direction Y, both of which are adjacent to the first side wall 111a. Correspondingly, the protrusion 112 can include a fourth side wall 112a close to the flexible screen 30 along the first direction X, and a fifth side wall 112b and a sixth side wall 112c arranged along the second direction Y. In addition, the fifth side wall 112b and the sixth side wall 112c can be the side wall facing the fixing member 51.

[0116] Specifically, the fourth side wall 112a can be coplanar with the first side wall 111a, the fifth side wall 112b can be coplanar with the second side wall 111b, and the sixth side wall 112c can be coplanar with the third side wall 111c. Here, "coplanar" can be understood as that there is no obvious boundary line between the two surfaces in the macroscopic view.

[0117] In the process of installing the fixing member 51 on the main shaft 11, glue can be provided in the recess 111 (the glue can be provided on the first sidewall 111a, the second sidewall 111b and the third sidewall 111c described above), and the fixing member 51 is arranged in the recess 111, specifically, the first end 511A of the body portion of the fixing member 51 can be installed in the recess 111, so that the fixing member 51 is bonded with the recess 111. Since the sidewalls of the protruding portion 112 and the sidewalls of the recess 111 are located in the same plane, the glue in the recess 111 can be extruded onto the inner sidewalls (for example, the fourth sidewall 112a, the fifth sidewall 112b and the sixth sidewall 112c described above) of the protruding portion 112, so that the fixing member 51 is bonded with the protruding portion 112. Among them, the glue in the recess 111 is a part of the bonding layer, and the glue arranged on the sidewalls of the protruding portion 112 is another part of the bonding layer. Through the above arrangement, it is beneficial to improve the assembly efficiency between the fixing member 51 and the main shaft 11.

[0118] Further, with reference to FIGS. 13 and 14, the first end of the body portion can be provided with a plurality of grooves 5161, the plurality of grooves 5161 are arranged at intervals along the second direction Y, and at least part of the grooves 5161 can extend along the third direction Z. By arranging a plurality of grooves 5161, it is beneficial that the glue in the recess 111 can be extruded onto the sidewalls of the protruding portion 112 through the plurality of grooves 5161, so that the fixing member 51 is bonded with the protruding portion 112.

[0119] Further, with reference to FIGS. 14 and 15, the first end 511A of the body portion can be provided with a plurality of protrusions 5162, and in the first direction X, the plurality of protrusions 5162 can be located on the side of the body portion facing the flexible screen 30. By arranging a plurality of protrusions 5162, it is beneficial to further increase the bonding area between the first end 511A of the body portion and the recess 111, and further improve the connection reliability between the fixing member 51 and the recess 111.

[0120] In some embodiments, in combination with FIGS. 6 to 9 and the description, the protruding portion 112 can further include a first protruding portion 118 and a second protruding portion 119, the first protruding portion 118 can be located on one side of the recess 111 along the first direction X, and the number of the second protruding portion 119 is two, and in the second direction Y, the first protruding portion 118 can be located between the two second protruding portions 119.

[0121] The shapes of the first protruding portion 118 and the second protruding portion 119 can be set according to actual needs. For example, in the third direction Z, the dimension of the first protruding portion 118 in the third direction Z can be greater than or equal to the dimension of the second protruding portion 119 in the third direction Z, or the protruding height of the first protruding portion 118 is greater than the protruding height of the second protruding portion 119. For another example, the dimension of the first protruding portion 118 in the second direction Y is greater than the dimension of each second protruding portion 119 in the second direction Y. The embodiments of the present application do not limit this.

[0122] For example, the recessed portion 111 can be a substantially rectangular groove. Correspondingly, the first protruding portion 118 can be arranged along the long side of the rectangular groove, so that the first protruding portion 118 is located at one side of the recessed portion 111 in the first direction X. As described in the above embodiments, at least part of the fourth side wall 112a can be located at the side of the first protruding portion 118 facing the fixing member 51. For example, the fixing member 51 can be bonded with the fourth side wall 112a on the first protruding portion 118.

[0123] For example, one second protruding portion 119 can be arranged along one side short side of the rectangular groove, so that the one second protruding portion 119 is located at one side of the recessed portion 111 in the second direction Y (for example, the upper side of the recessed portion 111 in FIG. 8). As described in the above embodiments, the fifth side wall 112b can be located at the side of the one second protruding portion 119 facing the fixing member 51. For example, the fixing member 51 can be bonded with the fifth side wall 112b on the one second protruding portion 119. Another second protruding portion 119 can also be arranged along the other side short side of the rectangular groove, so that the other second protruding portion 119 is located at the other side of the recessed portion 111 in the second direction Y (for example, the lower side of the recessed portion 111 in FIG. 8). As described in the above embodiments, the sixth side wall 112c can be located at the side of the other second protruding portion 119 facing the fixing member 51. For example, the fixing member 51 can be bonded with the sixth side wall 112c on the other second protruding portion 119.

[0124] Through the above arrangement, it is beneficial to further increase the connection area of the fixing member 51 and the protruding portion 112, and thus it is beneficial to improve the connection reliability between the fixing member 51 and the main shaft 11.

[0125] It should be noted that in some other embodiments, the protruding portion 112 can also only include the first protruding portion 118, and the two second protruding portions 119 can be omitted.

[0126] Further, in some embodiments, the protruding portion 112 can also include a third protruding portion 1182, the third protruding portion 1182 can be located at one side of the recessed portion 111 in the first direction X, and the third protruding portion 1182 can also be located between the first protruding portion 118 and the second protruding portion 119.

[0127] For example, the number of the third protruding portions 1182 can be two, one third protruding portion 1182 can be located between one second protruding portion 119 and the first protruding portion 118, and the other third protruding portion 1182 can be located between the other second protruding portion 119 and the first protruding portion 118. As described in the above embodiments, the fourth side wall 112a can also be located on the side of the third protruding portion 1182 facing the fixing member 51. For example, the fixing member 51 can be bonded with the fourth side wall 112a on the third protruding portion 1182.

[0128] In addition, in the thickness direction of the main shaft, i.e., in the third direction Z, the first protruding portion 118 and the second protruding portion 119 can be higher than the third protruding portion 1182. For example, in the third direction Z, the size of the first protruding portion 118 and the second protruding portion 119 along the third direction Z can be greater than the size of the third protruding portion 1182 along the third direction Z, or the height of the protrusion of the first protruding portion 118 and the second protruding portion 119 is greater than the height of the protrusion of the third protruding portion 1182.

[0129] Further, the top surface of the end of the third protruding portion 1182 away from the support surface 113 can be parallel to the support surface 113. Correspondingly, the second end 511B of the body portion can also be provided with a flat surface matched with the top surface of the third protruding portion 1182.

[0130] Of course, in some other embodiments, the third protruding portion 1182 can also be provided with other corresponding shapes according to actual needs, which are not specifically limited in the embodiments of the present application.

[0131] Through the above arrangement, it is beneficial to further increase the connection area of the fixing member 51 and the protruding portion 112, and further beneficial to improve the connection reliability between the fixing member 51 and the main shaft 11. Further, in the embodiments in which the second end 511B of the body portion covers the protruding portion 112, in the third direction Z, the second end 511B of the body portion can cover the first protruding portion 118, the second protruding portion 119 and the third protruding portion 1182.

[0132] In some embodiments, referring to FIG. 15, in the third direction Z, part of the protruding portion 112 can be higher than the flexible screen 30, for example, the first protruding portion 118 of the protruding portion 112 can be higher than the bending area 32 of the flexible screen 30. Through the above arrangement, the protruding portion 112 can play a protective role on the bending area 32 of the flexible screen 30. At the same time, since the height of the protruding portion 112 along the third direction Z is increased, it is also beneficial to further increase the connection area of the fixing member 51 and the protruding portion 112, and further beneficial to improve the connection reliability between the fixing member 51 and the main shaft 11.

[0133] FIG. 17 is a sectional view of the fixing member in FIG. 6 along the A-A sectional line. In some embodiments, referring to FIG. 17 and FIG. 15, the fixing member 51 can further include a stop portion 515. The stop portion 515 is connected with the second end 511B of the body portion, and in the first direction X, the stop portion 515 is located on the side of the body portion 511 away from the flexible screen 30, the stop portion 515 and the body portion 511 jointly enclose a recess 531, and the opening direction of the recess 531 is arranged to face the main shaft 11. The partial protruding portion 112 can be located in the recess 531. Specifically, the partial first protruding portion 118 can be located in the recess 531.

[0134] For example, the stop portion 515 can be substantially in a plate structure, the opening direction of the recess 531 enclosed by the stop portion 515 and the body portion 511 faces downward, and the partial protruding portion 112 can extend into the recess 531. Through the above arrangement, the partial protruding portion 112 can also be embedded in the fixing member 51, which is conducive to further increasing the connection reliability between the fixing member 51 and the main shaft 11.

[0135] Further, the partial protruding portion 112 can also be bonded in the recess 531. For example, glue can also be arranged in the recess 531 to bond the stop portion 515 and the protruding portion 112. This is conducive to further increasing the connection area between the fixing member 51 and the protruding portion 112, and in turn, is conducive to improving the connection reliability between the fixing member 51 and the main shaft 11.

[0136] In some embodiments, in the third direction Z, the first end 515A of the stop portion is closer to the first end 511A of the body portion than the second end 515B of the stop portion. Further, in the first direction X, the size H1 of the first end 515A of the stop portion can be smaller than the size H2 of the second end 515B of the stop portion. For example, the first end 515A of the stop portion can be the lower end of the stop portion 515 in FIG. 17, and the second end 515B of the stop portion can be the upper end of the stop portion 515 in FIG. 17.

[0137] Through the above arrangement, when the electronic device 1 falls, the stop portion 515 is easily affected by the impact force. Since in the first direction X, the size H2 of the second end 515B of the stop portion is larger, the second end 515B of the stop portion is not easily broken under the action of the impact force, which is conducive to improving the reliability of the fixing member 51.

[0138] Correspondingly, referring to FIG. 16 and FIG. 15, the partial protrusion 112 located in the groove 531 comprises a matching block 115. Specifically, the partial first protrusion 118 located in the groove 531 comprises the matching block 115. In the third direction Z, the first end 115A of the matching block is farther away from the first end 511A of the body portion than the second end 115B of the matching block, and in the first direction X, the size D1 of the first end 115A of the matching block can be smaller than the size D2 of the second end 115B of the matching block. For example, the matching block 115 can be located at the end of the protrusion 112 away from the support surface 113, the first end 115A of the matching block can be the upper end of the matching block 115 in FIG. 16, and the second end 115B of the matching block can be the lower end of the matching block 115 in FIG. 16.

[0139] Through the above arrangement, the matching block 115 can be adaptively installed in the groove 531, and when the electronic device 1 falls, the matching block 115 is also subjected to the impact force. Since the size D2 of the second end 115B of the matching block is larger in the first direction X, the second end 115B of the matching block is not easy to break under the action of the impact force, which is beneficial to improve the reliability of the main shaft 11.

[0140] Further, referring to FIG. 15 and FIG. 17, the stop portion 515 can comprise a first force receiving surface 5153 and a first matching surface 5151, and the first force receiving surface 5153 and the first matching surface 5151 are arranged along the first direction X. Among them, the first force receiving surface 5153 is reused as the groove wall of the groove 531. For example, the first force receiving surface 5153 can be located on the left side of the stop portion 515, and the first matching surface 5151 can be located on the right side of the stop portion 515.

[0141] In the third direction Z, the first end 5159 of the first force receiving surface can be closer to the first end 511A of the body portion than the second end 5158 of the first force receiving surface, and in the first direction X, the distance between the first end 5159 of the first force receiving surface and the first matching surface 5151 can be smaller than the distance between the second end 5158 of the first force receiving surface and the first matching surface 5151.

[0142] For example, the first end 5159 of the first force receiving surface can be the lower end of the first force receiving surface 5153, and the second end 5158 of the first force receiving surface can be the upper end of the first force receiving surface 5153. Correspondingly, the first matching surface 5151 can be parallel to the third direction Z. Through the above arrangement, in the first direction X, the size of the first end 515A of the stop portion can be smaller than the size of the second end 515B of the stop portion.

[0143] Further, referring to FIG. 15, FIG. 16 and FIG. 17, the first mating surface 5151 of the stop portion 515 and the first protruding portion 118 are flush with the outer side wall 117 of the fixing member 51. Specifically, the first mating surface 5151 of the stop portion 515 and the first protruding portion 118 are flush with the outer side wall 117 of the fixing member 51, which is conducive to improving the structural regularity of the electronic device and improving the aesthetic appearance of the electronic device.

[0144] Correspondingly, referring to FIG. 15 and FIG. 16, the matching block 115 can include a second force receiving surface 1153 and a second mating surface 1151. The second force receiving surface 1153 can be located between the second mating surface 1151 and the first force receiving surface 5153. For example, the second force receiving surface 1153 can be located on the right side of the matching block 115, and the second mating surface 1151 can be located on the left side of the matching block 115.

In the first direction X, the distance between the first end 1158 of the second force receiving surface and the second mating surface 1151 can be less than the distance between the second end 1159 of the second force receiving surface and the second mating surface 1151.

[0146] For example, the first end 1158 of the second force receiving surface can be the upper end of the second force receiving surface 1153, and the second end 1159 of the second force receiving surface can be the lower end of the second force receiving surface 1153. Correspondingly, the second mating surface 1151 can be parallel to the third direction Z. Through the above arrangement, in the first direction X, the size of the first end 115A of the matching block can be smaller than the size of the second end 115B of the matching block.

[0147] The present application does not limit the specific shape of the first force receiving surface 5153 and the second force receiving surface 1153. In some embodiments, the first force receiving surface 5153 and the second force receiving surface 1153 can be arc-shaped surfaces. Alternatively, in some embodiments, the first force receiving surface 5153 and the second force receiving surface 1153 can both be flat surfaces, so that the matching block 115 can be smoothly assembled into the groove 531.

[0148] In embodiments in which part of the protruding portion 112 can also be bonded in the groove 531, the matching block 115 of the protruding portion 112 can be bonded with the groove wall of the groove 531. For example, the first force receiving surface 5153 of the stop portion 515 can be bonded with the second force receiving surface 1153 of the matching block 115. This is conducive to further increasing the connection area between the fixing member 51 and the protruding portion 112, and in turn is conducive to improving the connection reliability between the fixing member 51 and the main shaft 11.

[0149] Fig. 18 is a sectional view of the protection mechanism in Fig. 6 along the C-C sectional line; Fig. 19 is a sectional view of the main shaft in Fig. 6 along the C-C sectional line; Fig. 20 is a sectional view of the fixing member in Fig. 6 along the C-C sectional line. In combination with the sectional views shown in Figs. 18, 19 and 20, in some embodiments, the size of the stop portion 515 in the second direction Y can also be changed, and accordingly, the size of the matching block 115 in the second direction Y can also be changed. In the first direction X, the size H1 of the first end 515A of the stop portion can be equal to the size H2 of the second end 515B of the stop portion. Accordingly, in the first direction X, the size D1 of the first end 115A of the matching block can be equal to the size D2 of the second end 115B of the matching block.

[0150] For example, the stop portion 515 can further include a first sub-surface 5155 arranged along the second direction Y with the first force receiving surface 5153, and the first sub-surface 5155 is arranged along the first direction with the first matching surface 5151. Moreover, the first sub-surface 5155 and the first matching surface 5151 can both be perpendicular to the first direction X, so that in the first direction X, the size H1 of the first end 515A of the stop portion can be equal to the size H2 of the second end 515B of the stop portion.

[0151] Accordingly, the matching block 115 can further include a second sub-surface 1155 arranged along the second direction Y with the second force receiving surface 1153, and the second sub-surface 1155 is arranged along the first direction X with the second matching surface 1151. Moreover, the second sub-surface 1155 and the second matching surface 1151 can both be perpendicular to the first direction X, so that in the first direction X, the size D1 of the first end 115A of the matching block can be equal to the size D2 of the second end 115B of the matching block.

[0152] In addition, in some other embodiments, the embodiments of the present application can also omit the stop portion 515 and the matching block 115. In the third direction Z, the second end 511B of the body portion can cover the first protruding portion 118 of the protruding portion 112. Wherein, the surface of the second end 511B of the body portion arranged towards the protruding portion 112 can be a plane, and the surface of the protruding portion 112 arranged towards the second end 511B of the body portion can also be a plane, and the two planes are arranged along the third direction Z and contact.

[0153] Fig. 21 is a sectional view of the protection mechanism in Fig. 6 along the B-B sectional line. In some embodiments, referring to Fig. 21, the protruding portion 112 can have a third force receiving surface 116. Specifically, the second protruding portion 119 of the protruding portion 112 can have the third force receiving surface 116.

[0154] In the first direction X, the first end 1161 of the third force receiving surface is closer to the flexible screen 30 than the second end 1163 of the third force receiving surface, and in the third direction Z, the distance between the first end 1161 of the third force receiving surface and the plane on which the support surface 113 is located can be greater than the distance between the second end 1163 of the third force receiving surface and the plane on which the support surface 113 is located.

[0155] For example, the third force receiving surface 116 can be located at one end of the protruding portion 112 away from the support surface 113. The first end 1161 of the third force receiving surface can be the left end of the third force receiving surface 116 in FIG. 21, and the second end 1163 of the third force receiving surface can be the right end of the third force receiving surface 116 in FIG. 21. In addition, in the third direction Z, the left end of the third force receiving surface 116 is higher than the right end of the third force receiving surface 116.

[0156] With the above arrangement, when the electronic device 1 falls, the fixing member 51 is pressed by the impact force to press the protruding portion 112, and since in the third direction Z, the first end 1161 of the third force receiving surface is higher than the second end 1163 of the third force receiving surface, the third force receiving surface 116 is beneficial to receive the pressing force from the fixing member 51, avoiding the fixing member 51 from tilting towards the flexible screen 30, and is beneficial to avoid the fixing member 51 from pressing the flexible screen 30, thereby avoiding damage to the flexible screen 30.

[0157] In some embodiments, the fixing member 51 can have a fourth force receiving surface 517. The fourth force receiving surface 517 is located on the side of the third force receiving surface 116 away from the support surface 113, and in the first direction X, the first end 5171 of the fourth force receiving surface can be closer to the flexible screen 30 than the second end 5173 of the fourth force receiving surface, and in the third direction Z, the distance between the first end 5171 of the fourth force receiving surface and the plane on which the support surface 113 is located can be greater than the distance between the second end 5173 of the fourth force receiving surface and the plane on which the support surface 113 is located.

[0158] For example, the fourth force receiving surface 517 can be located at one end of the fixing member 51 towards the support surface 113. The first end 5171 of the fourth force receiving surface can be the left end of the fourth force receiving surface 517 in FIG. 21, and the second end 5173 of the fourth force receiving surface can be the right end of the fourth force receiving surface 517 in FIG. 21. In addition, in the third direction Z, the left end of the fourth force receiving surface 517 is higher than the right end of the fourth force receiving surface 517.

[0159] With the above arrangement, the fourth force receiving surface 517 can cooperate with the third force receiving surface 116 to further avoid the fixing member 51 from tilting towards the flexible screen 30, and is beneficial to avoid the fixing member 51 from pressing the flexible screen 30, thereby avoiding damage to the flexible screen 30.

[0160] The embodiments of the present application do not limit the specific shape of the third stress surface 116 and the fourth stress surface 517. In some embodiments, the third stress surface 116 and the fourth stress surface 517 can both be arc-shaped surfaces. Alternatively, in some embodiments, the third stress surface 116 and the fourth stress surface 517 are both flat surfaces, which is beneficial to further improve the structural regularity of the protruding portion and the fixing member.

[0161] In combination with FIGS. 8 and 9, in some embodiments, the third stress surface 116 can be provided with a fixing hole 1161. Correspondingly, the side of the body portion 511 facing the support surface 113 can be provided with a protruding column, which can be located in the fixing hole 1161. Through the above arrangement, it is beneficial to further increase the connection reliability between the fixing member 51 and the protruding portion 112.

[0162] In some embodiments, continuing to refer to FIGS. 10, 11 and 12, the protection mechanism 50 can further include a support portion 513, which can be connected with the body portion 511.

[0163] In some embodiments, the body portion 511 and the support portion 513 can be connected by bonding, clamping, welding or fasteners. For example, the body portion 511 can also have a mounting groove 518, which can be located on the side of the body portion 511 close to the flexible screen 30, and part of the support portion 513 can be embedded in the mounting groove 518, so that the support portion 513 can be connected with the body portion 511 by the above connection methods.

[0164] In some embodiments, the strength of the support portion 513 can also be greater than that of the protection member 52.

[0165] For example, the metal material can be stainless steel, cast iron, aluminum alloy or magnesium alloy, etc. In some embodiments, the support portion 513 can also be obtained by metal injection molding (MIM), and the support portion 513 can also be referred to as a MIM part. Alternatively, in some other embodiments, the support portion 513 can also be formed by other processes, such as computer numerical control (CNC) machining, die casting, etc. In some embodiments, the surface of the support portion 513 can also be coated with a plating layer to further improve the appearance effect of the protection mechanism 50. For example, in some embodiments, the plating layer on the surface of the support portion 513 has the same color as the back cover of the electronic device 1, so that the appearance color of the electronic device 1 is uniform, thereby having a better appearance effect. In some embodiments, the plating layer can also block water, oxygen and other external factors from corroding the fixing member 51, thereby improving the quality of the electronic device 1.

[0166] In some embodiments, the support part 513 can also be connected with the protective part 52, and the application does not limit the connection mode between the support part 513 and the protective part 52.

[0167] As shown in FIGS. 11 and 12, the support part 513 can have a first extension part 5135 extending in a direction close to the flexible screen 30. For example, the first extension part 5135 can have a substantially flat structure. The first extension part 5135 can cover part of the flexible screen.

[0168] In some embodiments, the first extension part 5135 can be embedded in the protective part 52. Through the above arrangement, the protective part can also cover part of the flexible screen 30.

[0169] The first extension part 5135 and the protective part 52 can be an integrated structure formed by an integrated molding process. It should be noted that in the present embodiment, the first extension part 5135 and the protective part 52 are an integrated structure formed by injection molding. Specifically, the formed support part 513 is placed in a mold, and then a molten soft glue material is filled into the mold. After the molten soft glue material is cooled and solidified, the protective part 52 of the present embodiment is formed, and the first extension part 5135 of the support part 513 is embedded in the protective part 52 and forms an integrated structure with the protective part 52. Through the above arrangement, the connection between the first extension part 5135 and the protective part 52 can be stable.

[0170] Correspondingly, the first extension part 5135 can also be provided with a positioning hole 5237. The positioning hole 5237 can facilitate the positioning of the fixing part 51 in the mold. Further, through the positioning hole 5237, the connection reliability between the support part 513 and the protective part 52 can be further improved.

[0171] Alternatively, in some other embodiments, the first extension part 5135 of the support part 513 can also not be embedded in the protective part 52, and the fixing part 51 and the support part 513 are connected with the protective part 52 by other connection modes. As shown in FIGS. 22 and 23, the fixing part 51 can include a mounting column 60, the protective part 52 can include a mounting hole 528 penetrating through it, and the fixing part 51 and the protective part 52 can be connected through the mounting column 60 and the mounting hole 528. The mounting column 60 and the mounting hole 528 can be gap-fitted.

[0172] Through the above arrangement, since the mounting column 60 and the mounting hole 528 are gap-fitted, when the mounting position of the fixing part 51 relative to the main shaft 11 deviates, the gap between the mounting column 60 and the mounting hole 528 can absorb the assembly error, avoiding the problem that the bending radii of the two ends of the protective part 52 are inconsistent.

[0173] The body part 511 has a second extending part 519 extending in a direction close to the flexible screen 30, and the mounting column 60 can be located between the first extending part 5135 and the second extending part 519. For example, the second extending part 519 can have a substantially flat structure. One end of the mounting column 60 is in contact with the first extending part 5135, and the other end of the mounting column 60 is in contact with the second extending part 519.

[0174] Through the above arrangement, the protection piece 52 can be located between the first extending part 5135 and the second extending part 519, and the first extending part 5135 and the second extending part 519 can limit the protection piece 52, avoiding the protection piece 52 from being pulled out of the mounting column 60.

[0175] In some examples, the mounting column 60 can be connected with the first extending part 5135. For example, the mounting column 60 can be located at one end of the first extending part 5135 away from the support surface 113. The mounting column 60 and the first extending part 5135 can be an integrally formed structure.

[0176] Alternatively, in some examples, the mounting column 60 is connected with the second extending part 519. For example, the mounting column 60 can be located at one end of the second extending part 519 close to the support surface 113. The mounting column 60 and the second extending part 519 can be an integrally formed structure.

[0177] Based on the above structure, in combination with FIG. 15, the fixing piece 51 can be connected with the recessed part 111 and the protruding part 112 at the same time. Specifically, the first end 511A of the body part of the fixing piece 51 can be installed in the recessed part 111, so that the fixing piece 51 is connected with the recessed part 111, and the body part 511 of the fixing piece 51 can also be connected with the protruding part 112, which is beneficial to increase the connection area between the fixing piece 51 and the main shaft, and further beneficial to increase the connection reliability. The structure of the recessed part 111 and the protruding part 112 on the main shaft can be as described in the above embodiments, which will not be described here. In addition, the structure of the body part 511 of the fixing piece 51 and the stop part 515 can also be as described in the above embodiments, which will not be described here.

[0178] Referring to FIG. 24, it can be seen that the distance between the protection piece 52 and the flexible screen 30 along the third direction Z is small, and the bending radius of the protection piece 52 is large. For example, the bending radius of the protection piece 52 with a height of T1 is R1, the bending radius of the protection piece 52 with a height of T2 is R2, and the bending radius of the protection piece 52 with a height of T3 is R3; wherein T1 < T2 < T3, R1 > R2 > R3.

[0179] Further, since the mounting column 60 penetrates the guard 52, the part of the guard 52 fixed with the fixing member 51 has a small size along the third direction Z, and the distance between the guard 52 and the flexible screen 30 along the third direction Z is small. Through the above arrangement, since the distance between the guard 52 and the flexible screen 30 along the third direction Z is small, the bending radius of the guard 52 is large, and the time for the guard 52 to reach the yield material of the bending material is long, which is beneficial to improve the phenomenon of fracture or failure deformation of the guard 52 after long-term use, and further improve the reliability of the guard 52.

[0180] The embodiment of the present application also provides a rotating mechanism, which can be any of the rotating mechanisms described above. The rotating mechanism 10 includes a main shaft 11, a first rotating shaft assembly 12 and a second rotating shaft assembly 13. The first rotating shaft assembly 12 and the second rotating shaft assembly 13 are respectively located on both sides of the main shaft 11, and the first rotating shaft assembly 12 and the second rotating shaft assembly 13 are respectively rotatably connected with the main shaft 11, so that the first rotating shaft assembly 12 and the second rotating shaft assembly 13 can respectively rotate relative to the main shaft 11.

[0181] The main shaft 11 can be provided with a recess 111 and a protrusion 112 arranged along the first direction X. The protrusion 112 can be arranged along part of the edge of the recess 111, and the side wall of the protrusion 112 can be coplanar with the side wall of the recess 111.

[0182] The embodiment of the present application also provides a protection mechanism, which can be any of the protection mechanisms described above. The protection mechanism 50 includes a fixing member 51 and a guard 52 connected with each other. The fixing member 51 includes a support part 513 and a body part 511 connected with each other. The support part 513 can have a first extension part 5135 bent and extended to the first side of the fixing member 51. The body part 511 has a second extension part 519 bent and extended to the first side of the fixing member 51. The first side of the fixing member 51 is the side where the flexible screen 30 is located.

[0183] The fixing member 51 includes a mounting column 60, which can be located between the first extension part 5135 and the second extension part 519. The mounting column 60 can be connected with the first extension part 5135, or the mounting column 60 is connected with the second extension part 519.

[0184] The guard 52 can include a mounting hole 528 penetrating the guard 52. The fixing member 51 and the guard 52 can be connected through the mounting column 60 and the mounting hole 528. The mounting column 60 and the mounting hole 528 can be gap-fitted.

[0185] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
