[0002] The present application claims priority to the Chinese Patent Application No. 202410472985.1, filed on April 17, 2024, and entitled “Electronic device”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the field of electronic devices, and in particular to an electronic device. BACKGROUND

[0004] With the gradual maturity of flexible display screen technology, the display mode of electronic devices has changed greatly. Foldable flexible display screen mobile phones, foldable flexible display screen tablets, and wearable electronic devices with foldable flexible display screens are important evolution directions of future smart electronic devices.

[0005] The edge of the flexible display screen is generally covered by a protective structure to protect the edge of the flexible display screen from wear and collision. In order to avoid the protective structure hindering the bending or flattening movement of the flexible display screen, the protective structure usually does not extend to the bending area of the flexible display screen. If the edge of the bending area of the flexible display screen is exposed, on the one hand, it will affect the appearance quality of the electronic device, and on the other hand, the flexible display screen is also easy to be out of contact with the supporting structure of the electronic device due to the edge being subjected to external force, so the flexible display screen has the risk of bulging relative to the supporting structure, affecting the use reliability of the electronic device. SUMMARY

[0006] The present application provides an electronic device to shield the edge of the bending area of the flexible display screen of the electronic device by using a shielding assembly, thereby improving the use reliability of the electronic device.

[0007] In a first aspect, the present application provides an electronic device, which comprises a first shell, a second shell, a rotating shaft mechanism, a flexible display screen, a first retaining edge, a second retaining edge, and two shielding assemblies. The first shell and the second shell are respectively arranged on two sides of the rotating shaft mechanism, and the flexible display screen can continuously cover the first shell, the rotating shaft mechanism, and the second shell. The rotating shaft mechanism comprises a base, and the axial direction of the rotating shaft mechanism is defined as a first direction. Along the first direction, the base comprises two oppositely arranged end portions, and the two end portions respectively extend beyond the edges of the flexible display screen. The flexible display screen comprises a first fixed area, a second fixed area, and a bending area. The first fixed area is fixed to the first shell, the second fixed area is fixed to the second shell, and the bending area is connected between the first fixed area and the second fixed area, and the bending area is arranged opposite to the rotating shaft mechanism. The first retaining edge covers the edge of the first fixed area, and the second retaining edge covers the edge of the second fixed area. The two shielding assemblies are respectively arranged on the two end portions. Each shielding assembly comprises a cover body, a retaining block, and a stabilizing sheet. The cover body is fixed to the end portion, the retaining block is connected to the cover body, the retaining block is made of flexible material, and the retaining block covers the edge of the bending area. The stabilizing sheet is connected to the retaining block, the stabilizing sheet is made of flexible material, the thickness of the stabilizing sheet is less than the thickness of the retaining block, one end of the stabilizing sheet is pressed between the first retaining edge and the first fixed area, and the other end of the stabilizing sheet is pressed between the second retaining edge and the second fixed area.

[0008] In the present application, during the switching process of the electronic device from the unfolded state to the closed state, the retaining block and the stabilizing sheet can bend with the flexible display screen. During the switching process of the electronic device from the closed state to the unfolded state, the retaining block and the stabilizing sheet can gradually flatten with the flexible display screen. Therefore, in the unfolded state, the closed state, and the intermediate state, the retaining block and the stabilizing sheet can shield the edges of the flexible display screen, thereby reducing the risk of the edges of the flexible display screen being separated from the supporting surface of the rotating shaft mechanism due to external force, and improving the reliability of the flexible display screen. Moreover, since the thickness of the stabilizing sheet is relatively thin, the problem of increasing the overall thickness of the electronic device caused by the thick stabilizing sheet can be avoided on the premise of stacking the two ends of the stabilizing sheet with the first retaining edge and the second retaining edge, thereby helping to realize the lightweight design of the electronic device.

[0009] In some embodiments, the retaining block can be made of soft rubber material, such as thermoplastic polyurethane rubber. The stabilizing sheet can be made of steel or polyimide material.

[0010] In some embodiments, the stabilizing sheet can include a first sub-stabilizing sheet and a second sub-stabilizing sheet, and the first sub-stabilizing sheet and the second sub-stabilizing sheet are respectively connected to two ends of the stabilizing sheet. At least a part of the first sub-stabilizing sheet is arranged between the first stop edge and the first fixed area, and at least a part of the second sub-stabilizing sheet is arranged between the second stop edge and the second fixed area. By designing the stabilizing sheet as a split structure connected to two ends of the stop block, the risk of the overall stabilizing sheet being broken during the bending process of the electronic device can be reduced, and the use reliability of the shielding assembly can be improved.

[0011] In some embodiments, the stop block is provided with a first clamping groove and a second clamping groove at two ends in the second direction, and the first clamping groove and the second clamping groove are respectively arranged on the side of the stop block facing the flexible display screen. One end of the first sub-stabilizing sheet is embedded in the first clamping groove, and one end of the second sub-stabilizing sheet is embedded in the second clamping groove. This design can not only improve the connection reliability of the first sub-stabilizing sheet and the second sub-stabilizing sheet with the stop block, but also reduce the thickness of the connection position of the first sub-stabilizing sheet with the stop block and the thickness of the connection position of the second sub-stabilizing sheet with the stop block, thereby facilitating further reduction of the thickness of the electronic device.

[0012] In some embodiments, the stabilizing sheet can further include a third sub-stabilizing sheet, the third sub-stabilizing sheet is located between the first sub-stabilizing sheet and the second sub-stabilizing sheet, and the third sub-stabilizing sheet is fixed to the side of the stop block facing the flexible display screen. The third sub-stabilizing sheet can provide certain support and reinforcement to the stop block, thereby improving the overall structural reliability of the stop block.

[0013] In some embodiments, the side of the stop block facing the flexible display screen is provided with a third clamping groove, and the third sub-stabilizing sheet can be embedded in the third clamping groove, so as to improve the connection reliability of the third sub-stabilizing sheet with the stop block without increasing the thickness of the connection position of the third sub-stabilizing sheet with the stop block.

[0014] In some embodiments, the stabilizing sheet can be in a long strip structure, and a part of the stabilizing sheet is arranged between the stop block and the bending area. By designing the stabilizing sheet as an overall structure, the stabilizing sheet can be formed at one time, which not only can simplify the overall manufacturing process difficulty of the shielding assembly, but also is more convenient for positioning and assembling the shielding assembly.

At least part of the first limiting hook is arranged in the first sliding groove, and at least part of the second limiting hook is arranged in the second sliding groove. By using the limiting effect of the first sliding groove on the first limiting hook, the first limiting hook can be prevented from sliding out of the first sliding groove, thereby reducing the risk of the stabilizing sheet being pulled out between the first blocking edge and the flexible display under the action of external force, and improving the installation reliability of the stabilizing sheet in the electronic device. Similarly, by using the limiting effect of the two end groove walls of the second sliding groove on the second limiting hook, the second limiting hook can be prevented from sliding out of the second sliding groove, thereby reducing the risk of the stabilizing sheet being pulled out between the second blocking edge and the flexible display under the action of external force, and improving the installation reliability of the stabilizing sheet in the electronic device.

[0017] In some embodiments, the first limiting hook comprises a first wall, a second wall and a third wall, wherein the second wall is connected to the first wall and the third wall respectively, and the first wall and the third wall are connected to the two opposite sides of the second wall along the first direction, the first wall is connected to the stabilizing sheet, and the second wall and the third wall are arranged in the first sliding groove. By designing the first limiting hook in the above structure, the connection of the first limiting hook and the stabilizing sheet is facilitated, and part of the structure of the first limiting hook can be reliably limited in the first sliding groove. The second limiting hook comprises a fourth wall, a fifth wall and a sixth wall, wherein the fifth wall is connected to the fourth wall and the sixth wall respectively, and the fourth wall and the sixth wall are connected to the two opposite sides of the fourth wall along the first direction, the fourth wall is connected to the stabilizing sheet, and the fifth wall and the sixth wall are arranged in the second sliding groove. By designing the second limiting hook in the above structure, the connection of the second limiting hook and the stabilizing sheet is facilitated, and part of the structure of the second limiting hook can be reliably limited in the second sliding groove.

[0018] In some embodiments, the end of the stabilizing sheet away from the blocking block can have a first fixed part, the first fixed part is arranged beyond the side edge of the first fixed area, and the first limiting hook can be fixed to the stabilizing sheet by being connected to the first fixed part. The other end of the stabilizing sheet away from the blocking block can have a second fixed part, the second fixed part is arranged beyond the edge of the second fixed area, and the second limiting hook can be fixed to the stabilizing sheet by being connected to the second fixed part.

[0019] In some embodiments, the first limiting hook can be welded with the stabilizing sheet to improve the connection reliability of the two. Similarly, the second limiting hook can also be welded with the stabilizing sheet to improve the connection reliability of the two.

[0020] In some embodiments, the first limiting hook includes a first extension part and a first bent part, the first extension part is connected to one end of the stabilizing sheet, the first extension part is arranged beyond the side edge of the first fixing area, the first bent part is arranged at an angle with the first extension part, and part of the first bent part and the first extension part is arranged in the first sliding groove, so that the first limiting hook is limited by the first sliding groove. The second limiting hook includes a second extension part and a second bent part, the second extension part is connected to one end of the stabilizing sheet, the second extension part is arranged beyond the side edge of the second fixing area, the second bent part is arranged at an angle with the second extension part, and part of the second bent part and the second extension part is arranged in the second sliding groove, so that the second limiting hook is limited by the second sliding groove.

[0021] In some embodiments, the first bent part can be provided with a first sliding hole, and the first sliding groove is provided with a first guide protrusion which is slidingly arranged in the first sliding hole. By the sliding cooperation between the first guide protrusion and the first sliding hole, the sliding stability of the first limiting hook in the first sliding groove can be further improved. Similarly, the second bent part can be provided with a second sliding hole, and the second sliding groove is provided with a second guide protrusion which is slidingly arranged in the second sliding hole. By the sliding cooperation between the second guide protrusion and the second sliding hole, the sliding stability of the second limiting hook in the second sliding groove can be further improved.

[0022] In some embodiments, the first limiting hook, the second limiting hook and the stabilizing sheet can be an integral structure, so as to simplify the positioning and assembling process of the shielding assembly.

[0023] In some embodiments, the shielding assembly further includes a guide column. The cover includes a top wall, the top wall can be arranged on one side of the end portion facing the side where the flexible display screen is located, and the guide column is arranged between the top wall and the end portion; the stopper includes a sliding portion arranged opposite to the base, and the sliding portion is provided with a through hole, the stopper can be sleeved on the guide column through the through hole, so that the stopper can slide along the guide column in the thickness direction of the electronic device. In the unfolded state of the electronic device, the sliding portion is located at one end of the guide column close to the top wall, in the process of switching the electronic device from the unfolded state to the closed state, the stopper and the stabilizing sheet are bent with the flexible display screen, based on the sliding cooperation relationship between the sliding portion and the guide column, the sliding portion has the freedom of movement in the thickness direction of the electronic device, therefore the sliding portion can slide along the guide column towards the direction close to the end portion, through this design, the bending position of the stopper can realize smooth transition, and the stopper can realize a relatively large bending radius, so as to release the bending stress of the stopper, reduce the risk of plastic deformation of the stopper due to dead folding, and improve the structural reliability of the shielding assembly. After the electronic device is switched to the closed state, the sliding portion is located at one end of the guide column close to the end portion, in the process of switching the electronic device from the closed state to the unfolded state, as the flexible display screen is flattened, the stopper and the stabilizing sheet are also flattened synchronously, and the sliding portion slides along the guide column towards the direction close to the top wall, so that after the electronic device is switched to the unfolded state, the stopper and the stabilizing sheet return to the natural state without deformation.

[0024] In some embodiments, the guide column can be fixed to the top wall, so that the guide column can be reliably positioned between the top wall and the end portion. The gap between the end portion and the end of the guide column away from the top wall is smaller than the thickness of the stopper, so as to reduce the risk of the stopper separating from the guide column through the gap between the guide column and the end portion, and improve the movement reliability of the stopper.

[0025] In a specific implementation, the guide column and the top wall can be an integral structure, which can not only improve the structural strength of the cover as a whole, but also ensure the positional accuracy of the guide column, avoiding the design tolerance and assembly tolerance caused by separate processing and assembly of the guide column.

[0026] In some embodiments, the guide column can be fixed to the end portion, so that the guide column can be reliably positioned between the top wall and the end portion. The gap between the top wall and the end of the guide column away from the end portion is smaller than the thickness of the stopper, so as to reduce the risk of the stopper separating from the guide column through the gap between the guide column and the top wall, and improve the movement reliability of the stopper.

[0027] In a specific implementation, the guide column and the base can be an integral structure, which can not only improve the connection strength of the guide column and the base, but also ensure the positional accuracy of the guide column, avoiding the design tolerance and assembly tolerance caused by separate processing and assembly of the guide column.

[0028] In some embodiments, the cover further comprises an end cap connected to one end of the top wall away from the side edge of the flexible display screen in the first direction, the end cap being fixedly connected to the end portion so as to fix the cover as a whole to the end portion via the end cap.

[0029] In some embodiments, each end portion comprises a protruding portion arranged towards the side where the flexible display screen is arranged, each protruding portion comprising an end surface facing away from the other protruding portion. For each shielding assembly, the end cap of the cover can be arranged on the end surface of the protruding portion of the corresponding end portion, such that the protruding portion can be fixedly connected to the end cap with a relatively small thickness, thereby helping to reduce the axial length of the base and further reducing the overall length of the electronic device.

[0030] Exemplarily, the end cap and the end surface of the protruding portion can be fixedly connected by bonding or welding.

[0031] In some embodiments, the protruding surface of the protruding portion is provided with a groove, and the guide post can be arranged between the top wall and the groove bottom, such that the guide post does not occupy additional space of the base in the first direction, thereby helping to further reduce the axial length of the base.

[0032] In some embodiments, the sliding portion has an extension block towards one side of the cover, and at least part of the through hole is arranged in the extension block. When the shielding assembly is assembled, the extension block can extend into the groove so as to facilitate the sliding fit with the guide post in the groove.

[0033] In some embodiments, the cover can further comprise a first side wall and a second side wall, the arrangement direction of the first housing and the second housing being defined as a second direction, the first side wall and the second side wall being connected to two ends of the top wall respectively, and the first side wall and the second side wall being fixedly connected to the end portion respectively, such that the cover as a whole can be fixed to the end portion by using the first side wall and the second side wall.

[0034] In some embodiments, the stop block can be fixedly connected to the cover. Exemplarily, the shielding assembly can comprise a limiting member, the top wall, the stop block and the limiting member being arranged in sequence in the thickness direction of the electronic device, the stop block can be provided with a positioning hole, and the limiting member can be provided with a positioning post towards the stop block, the fixing post can be fixedly connected to the top wall after penetrating through the positioning hole, so as to fix the stop block to the top wall.

[0035] In a second aspect, the present application also provides a shielding assembly which can be used to shield the edge of a flexible display screen. The shielding assembly comprises a cover, a blocking piece and a stabilizing sheet. The cover is arranged on one side of the side edge of the flexible display screen. The blocking piece is connected to the cover and is made of flexible material. The blocking piece is arranged to cover the edge of the flexible display screen. The stabilizing sheet is connected to the blocking piece and is also made of flexible material. The thickness of the stabilizing sheet is less than that of the blocking piece. The two ends of the stabilizing sheet extend beyond the two ends of the blocking piece. The stabilizing sheet is arranged to cover the edge of the flexible display screen.

[0036] When the shielding assembly is applied to an electronic device, the cover is arranged on one side of the side edge of the flexible display screen, and the blocking piece and the stabilizing sheet cover the edge of the flexible display screen. During the switching process of the electronic device from the unfolded state to the closed state, the blocking piece and the stabilizing sheet can bend with the flexible display screen. During the switching process of the electronic device from the closed state to the unfolded state, the blocking piece and the stabilizing sheet can gradually flatten with the flexible display screen. Therefore, the blocking piece and the stabilizing sheet can shield the exposed edge of the flexible display screen in the unfolded state, the closed state and the intermediate state, thereby reducing the risk that the edge of the flexible display screen is separated from the support surface of the rotating shaft mechanism due to external force, and improving the reliability of the flexible display screen. In addition, since the thickness of the first stabilizing sheet and the second stabilizing sheet is less than that of the blocking piece, the thickness of the edge area of the electronic device can be reduced to some extent, thereby helping to reduce the overall thickness of the electronic device.

[0037] In some embodiments, the blocking piece can be made of soft rubber material, such as thermoplastic polyurethane rubber. The stabilizing sheet can be made of steel or polyimide material.

[0038] In some embodiments, the stabilizing sheet can comprise a first sub-stabilizing sheet and a second sub-stabilizing sheet. The first sub-stabilizing sheet and the second sub-stabilizing sheet are respectively connected to the two ends of the blocking piece. The first sub-stabilizing sheet is arranged beyond one end of the blocking piece, and the second sub-stabilizing sheet is arranged beyond the other end of the blocking piece. By designing the stabilizing sheet as a split structure connected to the two ends of the blocking piece, the risk of the overall stabilizing sheet breaking during the bending process of the electronic device can be reduced, and the use reliability of the shielding assembly can be improved.

[0039] In some embodiments, the blocking piece is provided with a first clamping groove and a second clamping groove at the two ends in the second direction. The first clamping groove and the second clamping groove are respectively arranged on one side of the blocking piece. One end of the first sub-stabilizing sheet is embedded in the first clamping groove, and one end of the second sub-stabilizing sheet is embedded in the second clamping groove. This design can improve the connection reliability of the first sub-stabilizing sheet, the second sub-stabilizing sheet and the blocking piece, and can also reduce the thickness of the connection position of the first sub-stabilizing sheet and the blocking piece, and the thickness of the connection position of the second sub-stabilizing sheet and the blocking piece.

[0040] In some embodiments, the stabilizing sheet can further include a third sub-stabilizing sheet located between the first sub-stabilizing sheet and the second sub-stabilizing sheet and fixed to one side of the stop block. The third sub-stabilizing sheet can provide certain support and reinforcement to the stop block, thereby improving the overall structural reliability of the stop block.

[0041] In some embodiments, the side of the stop block facing the stabilizing sheet is provided with a third clamping groove, and the third sub-stabilizing sheet can be embedded in the third clamping groove, so as to improve the connection reliability of the third sub-stabilizing sheet and the stop block without increasing the thickness of the connection position of the third sub-stabilizing sheet and the stop block.

[0042] In some embodiments, the stabilizing sheet can have a long strip structure, and part of the stabilizing sheet is arranged on one side of the stop block. By designing the stabilizing sheet as a whole structure, the stabilizing sheet can be formed at one time, which not only simplifies the overall manufacturing process difficulty of the shielding assembly, but also facilitates the positioning and assembly of the shielding assembly.

[0043] In some embodiments, the side of the stop block facing the stabilizing sheet can be provided with one or more fixing protrusions, and the stabilizing sheet can be provided with one or more fixing holes, the fixing protrusions and the fixing holes being arranged one by one, and each fixing protrusion being fixed in the corresponding fixing hole, so as to fixedly connect the stop block and the stabilizing sheet in this way.

[0044] In some embodiments, the shielding assembly further includes a first limiting hook and a second limiting hook, the first limiting hook being connected to one end of the stabilizing sheet, and the second limiting hook being connected to the other end of the stabilizing sheet. The first limiting hook is used for sliding connection with the first stop edge of the electronic device, and the second limiting hook is used for sliding connection with the second stop edge of the electronic device. By limiting the first limiting hook and the second limiting hook with the first stop edge and the second stop edge, the sliding between the stabilizing sheet and the flexible display screen under external force can be reduced, and the installation reliability of the shielding assembly in the electronic device can be improved.

[0045] In some embodiments, the first limiting hook comprises a first wall, a second wall and a third wall, wherein the second wall is connected with the first wall and the third wall respectively, and the first wall and the third wall are connected to the opposite sides of the second wall respectively, the first wall is connected with the stabilizing sheet, and the second wall and the third wall are slidably connected with the first rim of the electronic device. By designing the first limiting hook in the above structure, the connection between the first limiting hook and the stabilizing sheet is facilitated, and the partial structure of the first limiting hook is reliably slidably connected with the first rim.

In use, the first housing 100 and the second housing 200 can rotate relative to or away from each other under the action of the hinge mechanism 300, so that the electronic device 1000 can be closed or unfolded according to different use scenarios.

[0064] In the embodiment of the application, the electronic device 1000 can be an inner folding electronic device. In the closed state, the flexible display screen 400 is located on the inner side of the electronic device 1000. In FIG. 1, the relative position relationship between the hinge mechanism 300 and the two housings in the closed state of the inner folding electronic device 1000 is shown. Of course, in some other embodiments, the electronic device 1000 can also be an outer folding electronic device, and in the closed state, the flexible display screen 400 is located on the inner side of the electronic device 1000.

[0065] FIG. 3 is a partially exploded structural schematic diagram of the electronic device 1000 in the unfolded state shown in FIG. 1. Referring to FIG. 3, in the embodiment of the application, the first housing 100, the second housing 200, and the hinge mechanism 300 respectively have support surfaces arranged towards the flexible display screen 400, and the flexible display screen 400 can continuously cover the support surface 100a of the first housing 100, the support surface 200a of the second housing 200, and the support surface 300a of the hinge mechanism 300. In the unfolded state of the electronic device 1000, the support surface 100a of the first housing 100, the support surface 300a of the hinge mechanism 300, and the support surface 200a of the second housing 200 can be connected to form a flat support surface, thereby playing a role of flat support for the flexible display screen 400.

[0066] In some embodiments, the first housing 100 can include a first middle frame and a first back cover, and the second housing 200 can include a second middle frame and a second back cover, wherein the first middle frame is fixedly connected with the first back cover and can form a receiving space, and the second middle frame is fixedly connected with the second back cover and can form a receiving space. A side of the first middle frame away from the first back cover can serve as a support surface 100a of the first housing 100 for supporting the flexible display 400, and a side of the first back cover away from the middle frame can serve as an appearance surface of the first housing 100. Similarly, a side of the second middle frame away from the second back cover can serve as a support surface 200a of the second housing 200 for supporting the flexible display 400, and a side of the second back cover away from the second middle frame can serve as an appearance surface of the second housing 200.

[0067] In the receiving space of the first housing 100 and / or the second housing 200, an electronic device 1000 can also be installed with a circuit board, a battery, a microphone, a speaker, a camera, and other electronic components. The circuit board can integrate the main controller, the storage unit, the antenna module, the power management module, and other electronic components of the electronic device, and the battery can supply power to the flexible display, the circuit board, the microphone, the speaker, the camera, and other electronic components.

[0068] The process of the electronic device 1000 from the closed state shown in FIG. 1 to the unfolded state shown in FIG. 2, or the process from the unfolded state shown in FIG. 2 to the closed state shown in FIG. 1, is the process of the first housing 100 and the second housing 200 rotating around the rotation shaft mechanism 300 in opposite directions or relative directions, and in the above process, the flexible display 400 can be bent or flattened along with the rotation of the first housing 100 and the second housing 200.

[0069] Referring to FIG. 3, in the embodiment of the present application, the flexible display screen 400 comprises a first fixed area 410, a second fixed area 420 and a bending area 430, the bending area 430 being connected between the first fixed area 410 and the second fixed area 420. The first fixed area 410 is fixedly connected with the first shell 100, specifically, the first fixed area 410 can be fixedly connected with the support surface 100a of the first shell 100, and the connection manner includes but is not limited to bonding; the second fixed area 420 is fixedly connected with the second shell 200, specifically, the second fixed area 420 is fixedly connected with the support surface 200a of the second shell 200, and the connection manner includes but is not limited to bonding; the bending area 430 is opposite to the base 310 of the hinge mechanism 300. In the process of switching the electronic device 1000 from the unfolded state to the closed state, the bending area 430 of the flexible display screen 400 is bent, and the end of the first fixed area 410 away from the bending area 430 and the end of the second fixed area 420 away from the bending area 430 are close to each other; in the process of switching the electronic device 1000 from the closed state to the unfolded state, the bending area 430 of the flexible display screen 400 is gradually flattened, and the end of the first fixed area 410 away from the bending area 430 and the end of the second fixed area 420 away from the bending area 430 are away from each other.

[0070] It can be understood that in some other embodiments of the present application, the electronic device 1000 can further comprise a third shell connected between the first shell 100 and the second shell 200, and the first shell 100 and the third shell can be connected through a hinge mechanism 300, and the second shell 200 and the third shell can be connected through another hinge mechanism 300, and the electronic device 1000 in this form is a three-fold folding device.

[0071] In addition, in the embodiment of the present application, the electronic device 1000 can be unfolded and closed in a manual driving, electric driving or manual and electric hybrid driving manner. The manual driving manner means that the electronic device is unfolded and closed completely relying on the action force applied by the user; the electric driving manner means that the electronic device is unfolded and closed completely relying on the driving force output by the motor; the manual and electric hybrid driving means that the electronic device is unfolded and closed under the common driving of the action force applied by the user and the driving force output by the motor.

[0072] In the electronic device 1000 adopting the electric drive and hybrid drive mode, the motor can be accommodated in the accommodation space of the first shell 100 or the second shell 200, and the output shaft of the motor is in transmission connection with the rotating shaft mechanism 300, so that the first shell 100 and the second shell 200 are driven to rotate by driving the rotating shaft mechanism 300 to move, and the unfolding and closing of the electronic device 1000 are realized. In addition, the side frame of the electronic device 1000 can be provided with an operation button, which can be used to send an unfolding or closing signal to the controller of the electronic device 1000 when pressed, and the controller of the electronic device 1000 controls the motor to drive the rotating shaft mechanism to move after receiving the unfolding or closing signal. Exemplarily, the operation button can be arranged on the first shell 100, or can be arranged on the second shell 200.

[0073] In the embodiment of the present application, the rotating shaft mechanism 300 can include a base 310 and a rotating assembly (not shown in the figure), and the rotating assembly can be used to rotatably connect the first shell 100 and the second shell 200 with the base 310. The connection mode of the rotating assembly with the base 310, the first shell 100 and the second shell 200 can be various, for example, the rotating assembly can be rotatably connected with the base 310, and the rotating assembly can be fixedly connected, rotatably connected or slidably connected with the first shell 100 and the second shell 200, etc., and the present application does not make specific limitation thereto, as long as the first shell 100 and the second shell 200 can rotate relative to the base 310 to realize the folding and unfolding functions of the rotating shaft mechanism 300, which are all within the scope covered by the embodiment of the present application.

[0074] In addition, the rotating shaft mechanism 300 can not only limit the movement track of the first shell 100 and the second shell 200, but also support the flexible display screen 400, so that the bending part of the flexible display screen 400 is uniformly stressed in the unfolded state, the closed state and the intermediate state of the electronic device, and the length of the flexible display screen 400 can remain unchanged during the entire unfolding or closing process of the electronic device 1000, thereby improving the reliability of the flexible display screen 400.

[0075] The axial direction of the rotation shaft mechanism 300 is defined as the first direction x. In order to enable the first housing 100, the second housing 200, and the rotation shaft mechanism 300 to reliably support and protect the flexible display screen 400, the two ends of the first housing 100 and the two ends of the second housing 200 are arranged to protrude beyond the edges of the flexible display screen 400 along the first direction x. Correspondingly, the two ends of the rotation shaft mechanism 300 also protrude beyond the edges of the flexible display screen 400. In addition, in order to prevent the edges of the flexible display screen 400 from being exposed, the electronic device 1000 can further include a first edge cover 500 and a second edge cover 600. The first edge cover 500 and the second edge cover 600 can cover part of the edges of the flexible display screen 400, respectively, to protect the edges of the flexible display screen 400 from being damaged by abrasion and collision. In some embodiments, the first edge cover 500 and the second edge cover 600 can also be referred to as a "small A shell".

[0076] It should be noted that the edge region of the flexible display screen 400 can also be referred to as a peripheral region, and the display region inside the peripheral region is a display region. The display region of the flexible display screen 400 can be used to display images, videos, and the like. The peripheral region is usually used to arrange wires, and therefore, the first edge cover 500 and the second edge cover 600 do not cover the display region of the flexible display screen 400 and do not affect the display of the flexible display screen 400.

[0077] In the embodiments of the present application, the first edge cover 500 and the second edge cover 600 can both have a structure similar to a U shape. The first edge cover 500 can cover the edges of the first fixed region 410, and the second edge cover 600 can cover the edges of the second fixed region 420. Alternatively, it can be understood that, in the unfolded state of the electronic device 1000, the projection of the first edge cover 500 on a reference plane perpendicular to the thickness direction of the electronic device 1000 is within the projection range of the first housing 100 on the reference plane, the projection of the second edge cover 600 on the reference plane is within the projection range of the second housing 200 on the reference plane, and the projection of the first edge cover 500 on the reference plane does not overlap with the projection of the rotation shaft mechanism 300 on the reference plane, and the projection of the second edge cover 600 on the reference plane does not overlap with the projection of the rotation shaft mechanism 300 on the reference plane. That is, neither the first edge cover 500 nor the second edge cover 600 covers the bending region of the flexible display screen 400, so as to avoid hindering the bending or unfolding movement of the flexible display screen 400.

[0078] With reference back to FIG. 3, in some embodiments, the first retaining edge 500 includes a first retaining wall 510 and a second retaining wall 520, which are arranged substantially perpendicularly, the first retaining wall 510 is arranged on the edge of the first fixed area 410, and the second retaining wall 520 is arranged around the side of the first fixed area 410, so that the edge of the first fixed area 410 can be protected in the direction perpendicular to the flexible display screen 400, and the first fixed area 410 can also be protected in the circumferential direction. Similarly, the second retaining edge 600 includes a third retaining wall 610 and a fourth retaining wall 620, which are arranged substantially perpendicularly, the third retaining wall 610 is arranged on the edge of the second fixed area 420, and the fourth retaining wall 620 is arranged around the side of the second fixed area 420.

[0079] In addition, the edge of the support surface 100a of the first housing 100 can be provided with a first slot 110, the edge of the support surface 200a of the second housing 200 can be provided with a second slot 210, the second retaining wall 520 of the first retaining edge 500 can be inserted into the first slot 110, and the fourth retaining wall 620 of the second retaining edge 600 can be inserted into the second slot 210, so as to realize the fixed connection between the first retaining edge 500 and the first housing 100 and the fixed connection between the second retaining edge 600 and the second housing 200.

[0080] As described above, in the first direction x, the two side edges of the bending area of the flexible display screen 400 are not covered by the first retaining edge 500 and the second retaining edge 600. In order to avoid exposing the two side edges of the bending area 430, the electronic device 1000 usually further includes a shielding structure arranged for the bending area 430, which can flatten or bend the bending area 430 of the flexible display screen 400 during the unfolding or closing process of the electronic device 1000, so as to realize the protection of the bending area in different use states of the electronic device. In some electronic devices, the two ends of the shielding structure are usually pressed between the two side retaining edges and the flexible display screen 400, so as to reduce the risk of displacement of the shielding structure relative to the flexible display screen 400. However, due to the thickness of the shielding structure, the laminated design of the shielding structure and the retaining edge will increase the thickness of the electronic device 1000, which is not conducive to the lightweight design of the electronic device 1000.

[0081] Based on this, the embodiments of the present application provide a shielding assembly 700, which can reduce the thickness of the electronic device 1000 and reduce the difficulty of lightweight design of the electronic device 1000 by adopting a combined design of multiple components while realizing the shielding of the edges of the bending area 430 of the flexible display screen 400. The structure of the shielding assembly 700 and its application in the electronic device 1000 will be described below.

[0082] It should be noted that in the embodiments of the present application, the electronic device can include two shielding assemblies 700, which are respectively arranged at the two ends of the rotating shaft mechanism 300. Referring to FIG. 3, along the first direction x, the base 310 of the rotating shaft mechanism 300 includes two oppositely arranged end portions 311, which are the two ends of the rotating shaft mechanism 300 beyond the flexible display screen 400, and the two shielding assemblies 700 are respectively arranged at the two end portions.

[0083] FIG. 4 is a partial exploded view of an electronic device 1000 in an unfolded state from one perspective according to an embodiment of the present application, and FIG. 5 is a partial exploded view of the electronic device 1000 in the unfolded state from another perspective according to an embodiment of the present application. FIGS. 4 and 5 show the positional relationship between one of the shielding assemblies 700 and the corresponding end portion 311. In the embodiments of the present application, the shielding assembly 700 can include a cover 710, a blocking block 730, and a stabilizing sheet. The cover 710 is fixed to the end portion 311, the blocking block 730 is connected to the cover 710, and the cover of the blocking block 730 is arranged at the edge of the bending area 430 of the flexible display screen 400. The stabilizing sheet 740 is connected to the blocking block. In combination with FIG. 3, the arrangement direction of the first housing 100 and the second housing 200 of the electronic device 1000 in the unfolded state is defined as the second direction y. One end of the stabilizing sheet 740 along the second direction y covers the edge of the first fixed area 410, and the other end of the stabilizing sheet 740 along the second direction y covers the edge of the second fixed area 420. In a specific implementation, one end of the stabilizing sheet 740 is pressed between the first blocking edge 500 and the first fixed area 410, and the other end of the stabilizing sheet 740 is pressed between the second blocking edge 600 and the second fixed area 420. Therefore, the two ends of the stabilizing sheet 740 are fixed and hidden by the first blocking edge 500 and the second blocking edge 600, respectively. This can improve the appearance quality of the electronic device 1000, and can also reduce the risk of the two ends of the blocking block 730 being raised relative to the flexible display screen 400 by the limiting action of the first blocking edge 500 and the second blocking edge 600, thereby improving the use reliability of the electronic device 1000.

[0084] In the embodiments of the present application, the blocking block 730 and the stabilizing sheet 740 can both be flexible materials. In the process of switching the electronic device 1000 from the unfolded state to the closed state, the blocking block 730 and the stabilizing sheet 740 can bend with the flexible display screen 400. In the process of switching the electronic device 1000 from the closed state to the unfolded state, the blocking block 730 and the stabilizing sheet 740 can gradually flatten with the flexible display screen 400. Therefore, in the unfolded state, the closed state, and the intermediate state of the electronic device 1000, the blocking block 730 and the stabilizing sheet 740 can shield the edge of the flexible display screen 400, thereby reducing the risk of the flexible display screen 400 being separated from the supporting surface 300a of the rotating shaft mechanism 300 due to external force acting on the edge, and improving the reliability of the flexible display screen 400.

[0085] In addition, in the embodiment, by reasonably selecting the material of the stop block 730 and the stabilizing sheet 740, the thickness of the stabilizing sheet 740 can be less than the thickness of the stop block 730, so that the problem of increasing the overall thickness of the electronic device 1000 due to the thick stabilizing sheet 740 can be avoided on the premise of achieving the laminated design of the two ends of the stabilizing sheet 740 and the first stop edge 500 and the second stop edge 600, thereby helping to achieve the light and thin design of the electronic device 1000. For example, the material of the stop block 730 includes but is not limited to thermoplastic urethane (TPU), and the material of the stabilizing sheet 740 includes but is not limited to steel or polyimide (PI).

[0086] With reference to FIGS. 4 and 5, in some embodiments of the present application, the stabilizing sheet 740 can include a first sub-stabilizing sheet 741 and a second sub-stabilizing sheet 742, and the first sub-stabilizing sheet 741 and the second sub-stabilizing sheet 742 are respectively connected to the two ends of the stop block 730 along the second direction y. At least part of the first sub-stabilizing sheet 741 is arranged between the first stop edge 500 and the first fixed area 410, and at least part of the second sub-stabilizing sheet 742 is arranged between the second stop edge 600 and the second fixed area 420. By designing the stabilizing sheet 740 as a split structure connected to the two ends of the stop block 730, the risk of overall fracture of the stabilizing sheet 740 during the bending process of the electronic device 1000 can be reduced, and the use reliability of the shielding assembly 700 can be improved.

[0087] In one implementation, along the second direction y, the two ends of the stop block 730 can be respectively provided with a first clamping groove 732 and a second clamping groove 733, and the first clamping groove 732 and the second clamping groove 733 are respectively located on the side of the stop block 730 facing the flexible display screen 400. One end of the first sub-stabilizing sheet 741 can be embedded in the first clamping groove 732, and one end of the second sub-stabilizing sheet 742 can be embedded in the second clamping groove 733. This design can improve the connection reliability of the first sub-stabilizing sheet 741 and the second sub-stabilizing sheet 742 with the stop block 730, and can also reduce the thickness of the connection position of the first sub-stabilizing sheet 741 with the stop block 730 and the thickness of the connection position of the second sub-stabilizing sheet 742 with the stop block 730, thereby facilitating further reduction of the thickness of the electronic device 1000. For example, the depth of the first clamping groove 732 can be substantially equal to the thickness of the first sub-stabilizing sheet 741, and the depth of the second clamping groove 733 can be substantially equal to the thickness of the second sub-stabilizing sheet 742.

[0088] In some other embodiments, fixed protrusions can be arranged at both ends of the side of the block 730 facing the flexible display 400, and the first and second sub-stabilizing sheets 741 and 742 can be respectively provided with fixed holes. The fixed protrusion at one end of the block 730 can be fixed in the fixed hole of the first sub-stabilizing sheet 741, and the fixed protrusion at the other end of the block 730 can be fixed in the fixed hole of the second sub-stabilizing sheet 742, so that the first and second sub-stabilizing sheets 741 and 742 are respectively fixedly connected with the block 730.

[0089] In a specific implementation, the first sub-stabilizing sheet 741 and the block 730 can be fixedly connected by adhesion, and similarly, the second sub-stabilizing sheet 742 and the block 730 can be fixedly connected by adhesion.

[0090] In some embodiments, the shielding assembly 700 can further include a third sub-stabilizing sheet 743, which is located between the first and second sub-stabilizing sheets 741 and 742 and arranged at the side of the block 730 facing the flexible display 400. The third sub-stabilizing sheet 743 is also made of flexible material. For example, the third sub-stabilizing sheet 743 can be made of the same steel material or PI material as the first and second sub-stabilizing sheets 741 and 742, so that the third sub-stabilizing sheet 743 has better flexibility and provides certain support and reinforcement for the block 730, thereby improving the overall structural reliability of the block 730. The side of the block 730 facing the flexible display 400 is provided with a third clamping groove 734, and the third sub-stabilizing sheet 743 can be embedded in the third clamping groove 734, so as to improve the connection reliability of the third sub-stabilizing sheet 743 and the block 730 without increasing the thickness of the connection position of the third sub-stabilizing sheet 743 and the block 730.

[0091] Fig. 6 is a partially exploded structural schematic view of a shielding assembly 700 according to an embodiment of the present application. Referring to Figs. 4-6, in the embodiment of the present application, the shielding assembly 700 can further include a first limiting hook 770 and a second limiting hook 780, wherein the first limiting hook 770 is connected to one end of the stabilizing sheet 740, and the second limiting hook 780 is connected to the other end of the stabilizing sheet 740. It can be easily understood that, in the case where the stabilizing sheet 740 includes a first sub-stabilizing sheet 741 and a second sub-stabilizing sheet 742, the first limiting hook 770 can be specifically connected to one end of the first sub-stabilizing sheet 741 away from the stopper 730, and the second limiting hook 780 can be specifically connected to one end of the second sub-stabilizing sheet 742 away from the stopper 730. The second blocking wall 520 of the first blocking edge 500 is provided with a first sliding groove 521 at a position corresponding to the first limiting hook 770, the first sliding groove 521 extends along the second direction y, and at least part of the first limiting hook 770 is arranged in the first sliding groove 521; the fourth blocking wall 620 of the second blocking edge 600 is provided with a second sliding groove 621 at a position corresponding to the second limiting hook 780, the second sliding groove 621 extends along the second direction y, and at least part of the second limiting hook 780 is arranged in the second sliding groove 621. During the switching of the electronic device 1000 between the closed state and the unfolded state, with the bending and flattening of the first sub-stabilizing sheet 741 and the second sub-stabilizing sheet 742, the first limiting hook 770 can slide in the first sliding groove 521, and the second limiting hook 780 can slide in the second sliding groove 621.

[0092] By limiting the first limiting hook 770 with the two end groove walls of the first sliding groove 521, the first limiting hook 770 can be prevented from sliding out of the first sliding groove 521, thereby reducing the risk of the one end of the stabilizing sheet 740 being pulled out between the first blocking edge 500 and the flexible display screen 400 under the action of an external force, and improving the installation reliability of the stabilizing sheet 740 in the electronic device 1000. Similarly, by limiting the second limiting hook 780 with the two end groove walls of the second sliding groove 621, the second limiting hook 780 can be prevented from sliding out of the second sliding groove 621, thereby reducing the risk of the other end of the stabilizing sheet being pulled out between the second blocking edge 600 and the flexible display screen 400 under the action of an external force, and improving the installation reliability of the stabilizing sheet 740 in the electronic device 1000.

[0093] In some embodiments, the first limiting hook 770 is substantially in a "Z" shape, and includes a first wall 771, a second wall 772 and a third wall 773. The second wall 772 is connected to the first wall 771 and the third wall 773 respectively, and the first wall 771 and the third wall 773 are connected to the second wall 772 on opposite sides of the second wall 772 along the first direction x. The first wall 771 is connected to the stabilizing sheet 740, and the second wall 772 and the third wall 773 are arranged in the first sliding groove 521. By designing the first limiting hook 770 in the above structure, the connection between the first limiting hook 770 and the stabilizing sheet 740 is facilitated, and the part of the first limiting hook 770 can be reliably limited in the first sliding groove 521.

[0094] In addition, one end of the stabilizing sheet 740 along the second direction y (the end of the first sub-stabilizing sheet 741 away from the block 730) can have a first fixing portion 744 extending from one side edge of the stabilizing sheet 740 along the first direction x, and the first fixing portion 744 is arranged beyond the side edge of the flexible display 400. The first limiting hook 770 can be fixed to the stabilizing sheet 740 by being connected to the first fixing portion 744, for example, the first wall 771 of the first limiting hook 770 can be connected to the side of the first fixing portion 744 facing the side where the flexible display 400 is located. The first fixing portion 744 can extend into the first sliding groove 521, so that part or all of the first wall 771 can be limited in the first sliding groove 521 in addition to the second wall 772 and the third wall 773, thereby further improving the installation reliability of the stabilizing sheet 740.

[0095] In one implementation, the first limiting hook 770 and the stabilizing sheet 740 are in a split structure. In this way, the first limiting hook 770 and the stabilizing sheet 740 can be designed and processed separately, and the processing and forming process is simple, which helps to reduce the overall processing difficulty of the shielding assembly 700. For example, the first limiting hook 770 can be made of metal, and the first limiting hook 770 can be welded to the stabilizing sheet to improve the connection reliability of the two.

[0096] Similarly, the second limiting hook 780 is also substantially in a "Z" shape, and includes a fourth wall 781, a fifth wall 782 and a sixth wall 783. The fifth wall 782 is connected to the fourth wall 781 and the sixth wall 783 respectively, and the fourth wall 781 and the sixth wall 783 are connected to the fourth wall 781 on opposite sides of the fourth wall 781 along the first direction x. The fourth wall 781 is connected to the stabilizing sheet 740, and the fifth wall 782 and the sixth wall 783 are arranged in the second sliding groove 621. By designing the second limiting hook 780 in the above structure, the connection between the second limiting hook 780 and the stabilizing sheet 740 is facilitated, and the part of the second limiting hook 780 can be reliably limited in the second sliding groove 621.

[0097] In addition, the other end of the stabilizing sheet 740 along the second direction y (the end of the second sub-stabilizing sheet 742 away from the block 730) can have a second fixing portion 745 extending along the first direction x from a side edge of the stabilizing sheet 740, and the second fixing portion 745 is arranged beyond the side edge of the flexible display screen 400. The second limiting hook 780 can be fixed to the stabilizing sheet 740 by being connected with the second fixing portion 745, for example, the fourth wall 781 of the second limiting hook 780 can be connected with the side of the second fixing portion 745 away from the side where the flexible display screen 400 is located. The second fixing portion 745 can extend into the second sliding groove 621, so that part or all of the fourth wall 781 can be limited in the second sliding groove 621 in addition to the fifth wall 782 and the sixth wall 783, thereby further improving the installation reliability of the stabilizing sheet 740.

[0098] In an implementation, the second limiting hook 780 and the stabilizing sheet 740 are in a split structure. In this way, the second limiting hook 780 and the stabilizing sheet 740 can be separately designed and processed, and the processing and forming process is simple, which helps to reduce the overall processing difficulty of the shielding assembly. Exemplarily, the second limiting hook 780 can be made of metal, and the second limiting hook 780 can be fixed by welding to improve the connection reliability of the two.

[0099] FIG. 7 is a partially exploded structural schematic view of another shielding assembly provided in an embodiment of the present application. Referring to FIG. 7, in the embodiment of the present application, the stabilizing sheet 740 can be in a long strip structure, and in the unfolded state of the electronic device, the stabilizing sheet 740 extends along the second direction y, and the part of the stabilizing sheet 740 opposite to the block 730 is arranged between the block 730 and the bending area of the flexible display screen. By designing the stabilizing sheet 740 as a whole structure, the stabilizing sheet 740 can be formed at one time, which not only simplifies the overall manufacturing process difficulty of the shielding assembly, but also facilitates the positioning and assembly of the shielding assembly.

[0100] In some embodiments, the side of the block 730 facing the stabilizing sheet 740 can be provided with one or more fixing protrusions 735, and correspondingly, the stabilizing sheet 740 can be provided with one or more fixing holes 746, for example, FIG. 7 shows an example in which the fixing protrusions 735 and the fixing holes 746 are three respectively. The fixing protrusions 735 and the fixing holes 746 are arranged one by one, and each fixing protrusion 735 is fixed in the corresponding fixing hole 746, so as to fixedly connect the block 730 and the stabilizing sheet 740 in this way. In an implementation, the fixing protrusions 735 and the block 730 are in an integrated structure, and the block 730 can be filled in the fixing hole 746 of the stabilizing sheet 740 by a glue-pulling process in the injection molding process, so as to reduce the assembly and connection difficulty of the block 730 and the stabilizing sheet 740.

[0101] In some other embodiments, the width of the stabilizing sheet 740 in the first direction can be less than the width of the block 730 in the first direction, in which case, the block 730 can be provided with a clamping slot extending along the second direction y and penetrating through both side end faces of the block 730 along the second direction y, and the stabilizing sheet 740 can be embedded in the clamping slot to achieve the fixed connection of the stabilizing sheet 740 and the block 730, and this connection mode can reduce the thickness of the connection position of the stabilizing sheet 740 and the block 730, thereby helping to reduce the overall thickness of the electronic device.

[0102] In addition, in the present embodiment, the shielding assembly can also include a first limiting hook 770 and a second limiting hook 780, which are respectively arranged at both ends of the stabilizing sheet 740, and the structures of the two can be designed with reference to the embodiment shown in FIG. 6, which will not be repeated here.

[0103] FIG. 8 is an exploded structural schematic view of another stabilizing sheet 740 and the first and second retaining edges 500 and 600 provided in the present embodiment. Referring to FIG. 8, in the present embodiment, the first limiting hook 770 includes a first extension part 774 and a first bending part 775, the first extension part 774 is connected to one end of the stabilizing sheet 740, the first extension part 774 extends from one side edge of the stabilizing sheet 740 along the first direction x, and the first extension part 774 is arranged beyond the side edge of the flexible display screen, the first bending part 775 is arranged at an angle with the first extension part 774, and part of the first bending part 775 and the first extension part 774 are arranged in the first sliding groove 521, so as to achieve the limiting effect of the first limiting hook 770 by the first sliding groove 521. Exemplarily, the first bending part 775 and the first extension part 774 can be substantially perpendicular to each other, so as to reduce the occupied space of the first limiting hook 770 in the first direction x, thereby helping to reduce the overall length of the electronic device. In one implementation, the first limiting hook 770 and the stabilizing sheet 740 can be an integral structure, so that the first limiting hook 770 and the stabilizing sheet 740 as a whole can be formed at one time, thereby omitting the positioning and assembly process of the two.

[0104] Similarly, the second limiting hook 780 includes a second extension 784 and a second bending portion 785. The second extension 784 is connected to the other end of the stabilizing sheet 740, extends from one side edge of the stabilizing sheet 740 in the first direction x, and is arranged beyond the side edge of the flexible display screen. The second bending portion 785 is arranged at an angle with the second extension 784, and part of the second extension 784 and the second bending portion 785 are arranged in the second sliding groove 621, so that the second limiting hook 780 is limited by the second sliding groove 621. For example, the second bending portion 785 can be substantially perpendicular to the second extension 784, so as to reduce the space occupied by the second limiting hook 780 in the first direction x, thereby helping to reduce the overall length of the electronic device. In one implementation, the second limiting hook 780 and the stabilizing sheet 740 can be an integrated structure, so that the second limiting hook 780 and the stabilizing sheet 740 can be formed at one time, thereby omitting the positioning and assembly process of the two.

[0105] In the present embodiment, the first bending portion 775 can be provided with a first sliding hole 7751, and correspondingly, the first sliding groove 521 is provided with a first guide protrusion 5211 arranged in the first sliding hole 7751. During the sliding of the first bending portion 775 in the first sliding groove 521, the first guide protrusion 5211 and the first sliding hole 7751 can also form a sliding fit, and the sliding stability of the first limiting hook 770 in the first sliding groove 521 can be further improved by the fit therebetween, and the risk of the first limiting hook 770 sliding out of the first sliding groove 521 can be reduced. Similarly, the second bending portion 785 can be provided with a second sliding hole 7851, and correspondingly, the second sliding groove 621 is provided with a second guide protrusion 6211 arranged in the second sliding hole 7851. During the sliding of the second bending portion 785 in the second sliding groove 621, the second guide protrusion 6211 and the second sliding hole 7851 can also form a sliding fit, and the sliding stability of the second limiting hook 780 in the second sliding groove 621 can be further improved by the fit therebetween, and the risk of the second limiting hook 780 sliding out of the second sliding groove 621 can be reduced.

[0106] In addition, in the present embodiment, the stabilizing sheet can adopt the strip-shaped overall structure shown in FIG. 8. In this case, the stabilizing sheet 740, the first limiting hook 770, and the second limiting hook 780 can be designed as an integrated structure, thereby helping to further simplify the positioning and assembly of the overall shielding assembly.

[0107] Of course, in other embodiments, the stabilizing sheet 740 can also adopt a split structure as shown in FIG. 6, in which the first limiting hook 770 and the first sub-stabilizing sheet 741 can be in an integrated structure, and the second limiting hook 780 and the second sub-stabilizing sheet 742 can be in an integrated structure, so as to simplify the positioning and assembly of the shielding assembly to some extent, and reduce the risk of the overall stabilizing sheet 740 breaking during the bending process of the electronic device, thereby improving the use reliability of the shielding assembly.

[0108] Please refer to FIGS. 4 and 5 again. In the embodiments of the present application, the cover body includes a top wall 711, which is arranged on the side of the end portion 311 facing the side where the flexible display screen is located, and has a gap between the top wall 711 and at least part of the area of the end portion 311. In addition, the shielding assembly further includes a guide column 720, which is arranged between the top wall 711 and the end portion 311. As can be easily understood, the guide column 720 is arranged in the thickness direction of the electronic device 1000. The stopper 730 is located on the same side of the top wall 711 as the guide column 720. The stopper 730 includes a sliding portion 731, which is located opposite the base 310 in the thickness direction of the electronic device 1000. The sliding portion 731 is arranged on the edge of the bending area 430 of the flexible display screen 400. The sliding portion 731 is provided with a through hole 7311. The stopper 730 can be sleeved on the guide column 720 through the through hole 7311, and the through hole 7311 and the guide column 720 are in clearance fit. Therefore, the stopper 730 can slide along the guide column 720 in the thickness direction of the electronic device 1000, so that the constraint of the stopper 730 in the thickness direction of the electronic device 1000 is released.

[0109] It is worth mentioning that the stabilizing sheet 740 can be provided with a relief hole 747 corresponding to the position of the through hole 7311 of the stopper 730, so that the guide column 720 can pass through the relief hole 747 to realize sliding fit with the through hole 7311. As can be easily understood, in the case where the stabilizing sheet 740 includes the first sub-stabilizing sheet 741, the second sub-stabilizing sheet 742 and the third sub-stabilizing sheet 743, the above-mentioned relief hole 747 is arranged in the third sub-stabilizing sheet 743; in the case where the stabilizing sheet 740 adopts an integrated design, the above-mentioned relief hole 747 is arranged in the area of the stabilizing sheet 740 opposite the sliding portion 731 of the stopper 730.

[0110] In some embodiments, the cover body 710 can further include an end cover 712, which is connected to one end of the top wall 711 away from the stopper 730 in the first direction x, and the end cover 712 is fixedly connected with the end portion 311, so as to fix the cover body 710 as a whole on the end portion 311 through the end cover 712. In one implementation, the two end portions 311 of the base 310 respectively include a protruding portion 3111 arranged toward the side where the flexible display screen 400 is located, and each protruding portion 3111 includes an end face 3111a facing away from the other protruding portion 3111.

[0111] In some embodiments, for each shielding assembly 700, the end cover 712 of the cover body 710 can be covered on the end surface 3111a of the protrusion 3111 of the corresponding end portion 311. Exemplarily, the end cover 712 and the end surface 3111a of the protrusion 3111 can be fixed by bonding or welding. Such a design of fixing the end cover 712 on one side of the protrusion 3111 does not have a high requirement on the thickness (the size of the protrusion 3111 in the first direction x) of the protrusion 3111, and thus the protrusion 3111 can be fixedly connected with the end cover 712 with a relatively small thickness, thereby helping to reduce the axial length of the base 310, and further reducing the overall length of the electronic device 1000.

[0112] In some other embodiments, the protrusion 3111 can be provided with a mounting groove, and the end cover 712 can be inserted into the mounting groove, so that the end cover 712 and the protrusion 3111 can be fixedly connected.

[0113] In the embodiments of the present application, the cover body 710 can further include a first side wall 713 and a second side wall 714, which are respectively connected to two sides of the top wall 711 along the second direction y, and the first side wall 713 and the second side wall 714 are respectively fixedly connected with the end portion, so that the cover body 710 can be fixedly connected with the end portion by using the first side wall 713 and the second side wall 714. In specific implementations, the cover body 710 can include both the first side wall 713 and the second side wall 714 and the end cover 712, so as to improve the connection reliability of the cover body 710 and the end portion.

[0114] In one embodiment, the connection positions of the first side wall 713 and the top wall 711 and the connection positions of the second side wall 714 and the top wall 711 can be transitioned by a round corner, so as to reduce the risk of the cover body being collided. The size of the round corner can be designed according to the sizes of the top wall 711, the first side wall 713 and the second side wall 714, which is not limited in the present application. The position of the center line of the round corner connecting the first side wall 713 and the top wall 711 can be regarded as the dividing line between the first side wall 713 and the top wall 711, and the position of the center line of the round corner connecting the second side wall 714 and the top wall 711 can be regarded as the dividing line between the second side wall 714 and the top wall 711.

[0115] In addition, the first side wall 713 and the second side wall 714 can be respectively connected with two side surfaces of the protrusion 3111 along the second direction y, and the connection manner includes but is not limited to bonding. In this way, the contact area between the cover body 710 and the end portion 311 can be further increased, the connection strength of the cover body 710 and the end portion 311 can be improved, and the protrusion 3111 can be used to position the cover body 710 in the second direction y, thereby improving the assembly precision of the cover body 710 in the electronic device 1000.

[0116] In the embodiments of the present application, the cover 710 can be a one-piece structure. In one implementation, the cover 710 can be obtained by metal injection molding (MIM). Metal injection molding can obtain the cover 710 with high dimensional accuracy, thereby facilitating the cooperation of the shielding assembly and the base. In addition, the cover 710 obtained by metal injection molding has uniform structure and high relative density at each position, and thus has high strength, which can achieve better protection effect on the edge of the flexible display screen 400. For example, the material of the cover includes aluminum alloy, stainless steel, etc.

[0117] In the embodiments of the present application, the protruding surface of the protruding part 3111 is provided with a groove 31111, and the guide column 720 can be located between the top wall 711 and the groove bottom of the groove 31111, that is, the guide column 720 and the protruding part 3111 are stacked along the thickness of the electronic device 1000. Through this design, the guide column 720 does not occupy additional space of the base 310 in the first direction x, thereby helping to further reduce the axial length of the base 310.

[0118] In some embodiments, the side of the sliding part 731 towards the end cover 712 can have an extension block 7312, and at least part of the through hole 7311 is arranged on the extension block 7312. The width of the extension block 7312 along the second direction y is less than the width of the groove 31111 along the second direction y. When the shielding assembly 700 is assembled, the extension block 7312 can extend into the groove 31111, so as to facilitate the sliding cooperation with the guide column 720 in the groove 31111.

[0119] Please continue to refer to FIG. 4 and FIG. 5. In the embodiments of the present application, the guide column 720 can be fixed to the top wall 711, so that the guide column 720 can be reliably positioned between the top wall 711 and the end part. In one implementation, the guide column 720 and the top wall 711 can be a one-piece structure, which can improve the overall structural strength of the cover 710, and can also ensure the position accuracy of the guide column 720, avoiding the design tolerance and assembly tolerance caused by separate processing and assembly of the guide column 720.

[0120] In addition, the end of the guide column 720 away from the top wall 711 can be in contact with the end portion 311 or can be spaced apart from the end portion 311, and the present application does not limit the same. It is worth mentioning that in the case where the end of the guide column 720 away from the top wall 711 is spaced apart from the end portion 311, the gap between the end of the guide column 720 away from the top wall 711 and the end portion 311 is less than the thickness of the stop block 730, and specifically, the gap between the end of the guide column 720 away from the top wall 711 and the end portion 311 is less than the thickness of the sliding portion 731, so as to reduce the risk that the sliding portion 731 is separated from the guide column 720 by the gap between the guide column 720 and the end portion 311, and improve the movement reliability of the stop block 730.

[0121] In some other embodiments, the guide column 720 can also be fixed to the end portion 311, so that the positioning of the guide column 720 between the top wall 711 and the end portion can also be achieved. In one implementation, the guide column 720 and the end portion 311 can be an integral structure, or in other words, the guide column 720 and the base 310 are an integral structure, so that the connection strength of the guide column 720 and the base 310 can be improved, and the position accuracy of the guide column 720 can be ensured, and the design tolerance and assembly tolerance caused by separate processing and assembly of the guide column 720 can be avoided. The end of the guide column 720 away from the end portion 311 can be in contact with the top wall 711 or can be spaced apart from the top wall 711, and in the case where the end of the guide column 720 away from the end portion 311 is spaced apart from the top wall 711, the gap between the end of the guide column 720 away from the end portion 311 and the top wall 711 is less than the thickness of the stop block 730, and specifically, the gap between the end of the guide column 720 away from the end portion 311 and the top wall 711 is less than the thickness of the sliding portion 731, so as to reduce the risk that the sliding portion 731 is separated from the guide column 720 by the gap between the guide column 720 and the top wall 711, and improve the movement reliability of the stop block 730.

[0122] FIG. 9 is a schematic view of a partial cross-sectional structure of an electronic device 1000 in an unfolded state according to an embodiment of the present application, and FIG. 10 is a schematic view of a partial cross-sectional structure of an electronic device 1000 in a folded state according to an embodiment of the present application. Referring to FIGS. 9 and 10, in the unfolded state, the sliding portion 731 is located at one end of the guide column 720 close to the top wall 711, and the sliding portion 731 can be in contact with the top wall 711. During the switching of the electronic device 1000 from the unfolded state to the folded state, as the flexible display 400 is bent, the stop block 730 and the stabilizing sheet 740 are also bent synchronously, the first limiting hook 770 slides in the first sliding slot 521 relative to the first stop edge 500 towards the base 310, and the second limiting hook 780 slides in the second sliding slot 621 relative to the second stop edge 600 towards the base 310. Based on the sliding fit between the sliding portion 731 and the guide column 720, the sliding portion 731 has a degree of freedom of movement in the thickness direction of the electronic device 1000, and thus the sliding portion 731 can slide along the guide column 720 towards the end portion 311. In this way, the bending position of the stop block 730 can be smoothly transitioned, and the stop block 730 can achieve a relatively large bending radius, thereby releasing the bending stress of the stop block 730, reducing the risk of plastic deformation of the stop block 730 due to dead folding, and improving the structural reliability of the shielding assembly.

[0123] After the electronic device 1000 is switched to the folded state, the sliding portion 731 is located at one end of the guide column 720 close to the end portion 311, and the sliding portion 731 can be in contact with the end portion. During the switching of the electronic device 1000 from the folded state to the unfolded state, as the flexible display 400 is flattened, the stop block 730 and the stabilizing sheet 740 are also flattened synchronously, the first limiting hook 770 slides in the first sliding slot 521 relative to the first stop edge 500 away from the base 310, and the second limiting hook 780 slides in the second sliding slot 621 relative to the second stop edge 600 away from the base 310. The sliding portion 731 slides along the guide column 720 towards the top wall 711, so that after the electronic device 1000 is switched to the unfolded state, the stop block 730 and the stabilizing sheet 740 return to the natural state without deformation.

[0124] It should be noted that the above design of the relative sliding of the block and the cover can be an optional embodiment of the present application, and in some other embodiments, the block and the cover can also be designed in a relatively fixed structure. For example, in some embodiments, the block can be fixedly connected with the top wall of the cover. In a specific implementation, the shielding assembly can further include a limiting piece, and the top wall, the block and the limiting piece are arranged in sequence along the thickness direction of the electronic device. The block can be provided with a positioning hole, and the limiting piece can be provided with a positioning column on the side facing the block. When the cover, the block and the limiting piece are assembled, the positioning column can be fixedly connected with the top wall through the positioning hole, so as to fix the block to the top wall. Exemplarily, the limiting piece can be but is not limited to metal or soft rubber material, and the limiting piece can be fixedly connected with the top wall by welding or bonding.

[0125] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within 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.
