Description

TECHNICAL FIELD

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

[0002] 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.

[0003] The edge of the flexible display screen is generally covered by a protective structure to protect the edge of the flexible display screen from damage 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 support 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 support structure, affecting the use reliability of the electronic device. SUMMARY

[0004] The present application provides a shielding assembly and an electronic device to shield the edge of the bending area of the flexible display screen of the electronic device with the shielding assembly, thereby improving the use reliability of the electronic device.

[0005] In a first aspect, the present application provides a shielding assembly which can be used to shield the edge of a flexible display screen. The shielding assembly includes a cover body, a guide column and a stopper. The cover body is used to cover one side of the side edge of the flexible display screen, and the cover body includes a top wall. The guide column is arranged on one side of the top wall and can extend in a direction away from the top wall. The stopper is located on the same side of the top wall as the guide column, and the stopper is made of flexible material. The stopper is used to cover the edge of the flexible display screen, and the stopper includes a sliding part. The sliding part is provided with a through hole, and the stopper can be sleeved on the guide column through the through hole, so that the stopper can slide along the guide column.

[0006] When the shielding assembly is applied to the electronic device, the cover body can be arranged on one side of the side edge of the flexible display screen, and the blocking cover is arranged on the edge of the flexible display screen, so that the edge of the flexible display screen exposed outside is shielded by the shielding assembly, the risk that the flexible display screen is separated from the shaft mechanism due to the edge being subjected to external force is reduced, and the reliability of the flexible display screen is improved. Moreover, during the switching process of the electronic device from the unfolded state to the closed state, the blocking block can be bent with the flexible display screen, and the sliding part slides along the guide column towards the direction close to the end portion. In this way, the positions of the blocking block at all places during the bending process can achieve smooth transition, and the blocking block can achieve a relatively large bending radius, so that the bending stress of the blocking block can be released, the risk of plastic deformation of the blocking block is reduced, and the structural reliability of the shielding assembly is improved.

[0007] 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 blocking block, so as to reduce the risk that the blocking block is separated from the guide column through the gap between the guide column and the end portion, and improve the movement reliability of the blocking block.

[0008] In a specific implementation, the guide column and the top wall can be an integrated structure, so that the structural strength of the cover body as a whole can be improved, and the positional accuracy of the guide column can be ensured, avoiding the design tolerance and assembly tolerance caused by separate processing and assembly of the guide column.

[0009] In some embodiments, the blocking block further includes a first portion and a second portion connected to two ends of the sliding part, and the first portion and the second portion are respectively used to cover the edge of the flexible display screen. When the shielding assembly is applied to the electronic device, the first portion and the second portion can be relatively fixed with the first housing and the second housing on both sides of the shaft mechanism of the electronic device, so as to avoid the risk that the blocking block is lifted relative to the flexible display screen, and improve the use reliability of the shielding assembly.

[0010] In some embodiments, the blocking block can further include a first limiting wall and a second limiting wall, the first limiting wall is connected with the first portion and is arranged at an angle with the first portion, and the first limiting wall is used to block the side edge of the flexible display screen, the second limiting wall is connected with the second portion and is arranged at an angle with the second portion, and the second limiting wall is used to block the side edge of the flexible display screen. When the shielding assembly is applied to the electronic device, based on the relative positional relationship between the flexible display screen and the first limiting wall and the second limiting wall, the flexible display screen can limit the first limiting wall and the second limiting wall, reduce the risk of sliding of the first portion and the second portion to the display area of the flexible display screen, improve the installation positional accuracy of the blocking block, and avoid the influence of the blocking block on the display effect of the flexible display screen.

[0011] In some embodiments, the cover can further comprise an end cap connected to one end of the top wall away from the side edge of the flexible display screen, the end cap being used to be fixedly connected with the rotating shaft mechanism of the electronic device, so that the cover is fixedly connected with the rotating shaft mechanism of the electronic device as a whole through the end cap.

[0012] In some embodiments, the sliding part has an extension block on the side thereof facing the end cap, at least a part of the through hole being arranged in the extension block to facilitate the assembly of the sliding part, the guide column and the cover.

[0013] In some embodiments, the cover can further comprise a first side wall and a second side wall connected to two ends of the top wall respectively, the first side wall and the second side wall being used to be fixedly connected with the rotating shaft mechanism of the electronic device respectively. In this way, the cover can also be fixedly connected with the rotating shaft mechanism of the electronic device as a whole by using the first side wall and the second side wall.

[0014] In some embodiments, one end of the first side wall away from the top wall has a first hook used to be hung with the rotating shaft mechanism of the electronic device, and one end of the second side wall away from the top wall has a second hook used to be hung with the rotating shaft mechanism of the electronic device. By using the hanging relationship between the first hook and the second hook and the rotating shaft mechanism, the connection reliability of the cover and the rotating shaft mechanism can be further improved.

[0015] In some embodiments, the cover is of an integral structure, so that the combination between the parts of the cover is more compact, and the structural reliability of the cover is improved.

[0016] In some embodiments, the stopper can be made of soft rubber material, and the cover can be made of metal material. For example, the stopper can be obtained by injection molding, and the cover can be obtained by metal injection molding.

[0017] In a second aspect, the present application also provides an electronic device, which can include a first shell, a second shell, a rotating shaft mechanism, a flexible display screen, and two shielding assemblies. The first shell and the second shell are respectively arranged on two sides of the rotating shaft mechanism. The flexible display screen can continuously cover the first shell, the rotating shaft mechanism, and the second shell, and the flexible display screen includes a bending area arranged opposite to the rotating shaft mechanism. The rotating shaft mechanism includes a base. The axial direction of the rotating shaft mechanism is defined as a first direction. Along the first direction, the base includes two oppositely arranged end portions, and the two end portions respectively extend beyond the edges of the flexible display screen. The two shielding assemblies are respectively arranged at the two end portions. Each shielding assembly includes a cover, a guide column, and a blocking piece. The cover is fixed to the end portion. The cover includes a top wall, which can be arranged on one side of the end portion facing the side where the flexible display screen is located. The guide column is arranged between the top wall and the end portion. The blocking piece is located on the same side of the top wall as the guide column. The blocking piece is made of flexible material. The blocking piece is arranged on the edge of the flexible display screen to shield the edge of the flexible display screen, reduce the risk of the flexible display screen being separated from the rotating shaft mechanism due to external force acting on the edge, and improve the reliability of the flexible display screen. In addition, the blocking piece includes a sliding portion arranged opposite to the base. The sliding portion is provided with a through hole. The blocking piece can be sleeved on the guide column through the through hole, so that the blocking piece can slide along the guide column in the thickness direction of the electronic device.

[0018] 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 blocking piece can be bent with the flexible display screen. Since the sliding portion has the freedom of movement in the thickness direction of the electronic device, the sliding portion slides along the guide column towards the end portion. In this way, the positions of the blocking piece at all times during the bending process can achieve smooth transition, and the blocking piece can achieve a relatively large bending radius, thereby releasing the bending stress of the blocking piece, reducing the risk of plastic deformation of the blocking piece due to dead folding, and improving the structural reliability of the blocking piece. 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 blocking piece is also flattened, and the sliding portion slides along the guide column towards the top wall, so that after the electronic device is switched to the unfolded state, the blocking piece returns to the natural state without deformation.

[0019] 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 blocking piece, so as to reduce the risk of the blocking piece being separated from the guide column through the gap between the guide column and the end portion, and improve the movement reliability of the blocking piece.

[0020] In specific implementations, the guide column and the top wall can be an integral structure, which can improve the structural strength of the cover body as a whole, and ensure the position accuracy of the guide column, avoiding the design tolerance and assembly tolerance caused by separate processing and assembly of the guide column.

[0021] 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 end of the guide column away from the end portion and the top wall is smaller than the thickness of the stop block, so as to reduce the risk of the stop block being separated from the guide column by the gap between the guide column and the top wall, and improve the movement reliability of the stop block.

[0022] In specific implementations, the guide column and the base can be an integral structure, which can improve the connection strength of the guide column and the base, and ensure the position accuracy of the guide column, avoiding the design tolerance and assembly tolerance caused by separate processing and assembly of the guide column.

[0023] In some embodiments, the stop block further comprises a first portion and a second portion, the first portion and the second portion are respectively connected to the two ends of the sliding portion, and the first portion and the second portion are respectively arranged on the edges of the flexible display screen. The first portion and the second portion can be fixed relative to the first housing and the second housing on both sides of the rotation shaft mechanism of the electronic device, so as to avoid the risk of the stop block being raised relative to the flexible display screen, and improve the use reliability of the shielding assembly.

[0024] In some embodiments, the stop block further comprises a first limiting wall and a second limiting wall. In the first direction, the side of the stop block close to the cover body is arranged beyond the side edge of the flexible display screen, the first limiting wall is connected to the side of the first portion beyond the side edge of the flexible display screen, and the first limiting wall is arranged at an angle with the first portion, and the first limiting wall is arranged on the side edge of the flexible display screen; the second limiting wall is connected to the side of the second portion beyond the side edge of the flexible display screen, and the second limiting wall is arranged at an angle with the second portion, and the second limiting wall is arranged on the side edge of the flexible display screen. Based on the relative position relationship between the flexible display screen and the first limiting wall and the second limiting wall, the flexible display screen can limit the first limiting wall and the second limiting wall, reduce the risk of the first portion and the second portion sliding to the display area of the flexible display screen, improve the installation position accuracy of the stop block, and avoid the influence of the stop block on the display effect of the flexible display screen.

[0025] In some embodiments, the cover body further comprises an end cover, and in the first direction, the end cover is connected to the end of the top wall away from the side edge of the flexible display screen, and the end cover is fixedly connected with the end portion, so as to fix the cover body as a whole to the end portion through the end cover.

[0026] In some embodiments, each end portion comprises a protrusion arranged towards the side where the flexible display screen is located, and each protrusion comprises an end face facing away from the other protrusion. For each shielding assembly, the end cover of the cover body can be arranged on the end face of the protrusion of the corresponding end portion, and such a fixing manner enables the protrusion to be fixedly connected with the end cover 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.

[0027] Exemplarily, the end cover and the end face of the protrusion can be fixedly connected by bonding or welding.

[0028] In some embodiments, the protruding face of the protrusion is provided with a groove, and the guide column can be arranged between the top wall and the groove bottom, so that the guide column does not additionally occupy the space of the base in the first direction, thereby further helping to reduce the axial length of the base.

[0029] In some embodiments, the sliding portion has an extension block towards the side face of the end 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 to facilitate the sliding fit with the guide column in the groove.

[0030] In some embodiments, the cover body can further comprise a first side wall and a second side wall, and the arrangement direction of the first housing and the second housing is defined as a second direction. The first side wall and the second side wall are respectively connected to the two sides of the top wall, and the first side wall and the second side wall are respectively fixedly connected with the end portion. In this way, the first side wall and the second side wall can also be used to fix the cover body as a whole to the end portion.

[0031] In some embodiments, the two side faces of the end portion respectively have a first limiting step and a second limiting step. An end of the first side wall away from the top wall has a first hook, and the first hook is hung on the step face of the first limiting step. An end of the second side wall away from the top wall has a second hook, and the first hook is hung on the step face of the first limiting step, and the second hook is hung on the step face of the second limiting step. By using the cooperation relationship between the first hook and the first limiting step and the cooperation relationship between the second hook and the second limiting step, the connection reliability of the cover body and the base can be further improved.

[0032] In some embodiments, the electronic device further comprises a first retaining edge and a second retaining edge. The flexible display screen comprises a first fixed area and a second fixed area, which are respectively connected to two sides of the bending area, the first fixed area is fixed to the first housing, and the second fixed area is fixed to the second housing. 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. One end of the stopper is pressed between the first retaining edge and the flexible display screen, and the other end of the stopper is pressed between the second retaining edge and the flexible display screen. In this way, the two ends of the stopper are fixed and hidden by the first retaining edge and the second retaining edge respectively. On the one hand, the appearance of the electronic device can be improved, and on the other hand, the limiting effect of the first retaining edge and the second retaining edge can be used to reduce the risk of the two ends of the stopper being raised relative to the flexible display screen, thereby improving the use reliability of the electronic device.

[0033] In some embodiments, the first retaining edge comprises a first retaining wall and a second retaining wall, the first retaining wall covers the edge of the first fixed area, and the second retaining wall surrounds the side of the first fixed area. In this way, the protective effect of the first fixed area in the direction perpendicular to the flexible display screen can be achieved, and the protection of the first fixed area in the circumferential direction can also be achieved.

[0034] In some embodiments, the second retaining edge comprises a third retaining wall and a fourth retaining wall, the third retaining wall covers the edge of the second fixed area, and the fourth retaining wall surrounds the side of the second fixed area. In this way, the protective effect of the second fixed area in the direction perpendicular to the flexible display screen can be achieved, and the protection of the second fixed area in the circumferential direction can also be achieved.

[0035] In a third aspect, the present application further provides an electronic device, which can include a first shell, a second shell, a rotating shaft mechanism, a flexible display screen, and two shielding assemblies. The first shell and the second shell are respectively arranged on two sides of the rotating shaft mechanism. The flexible display screen can continuously cover the first shell, the rotating shaft mechanism, and the second shell. The flexible display screen includes a bending area arranged opposite to the rotating shaft mechanism. The rotating shaft mechanism includes a base. The axial direction of the rotating shaft mechanism is defined as a first direction. Along the first direction, the base includes two oppositely arranged end portions, which respectively extend beyond the edges of the flexible display screen. Each end portion includes a protruding portion arranged towards the side where the flexible display screen is located. Each protruding portion includes an end face facing away from the other protruding portion. The two shielding assemblies are respectively arranged on the two end portions. Each shielding assembly includes a cover. The cover is fixed to the end portion. The cover can include a top wall and an end cover. The end cover is fixed to the end face of the protruding portion. The top wall is connected to the end cover. The top wall is arranged on the protruding face of the protruding portion. With reference to a plane perpendicular to the thickness direction of the electronic device in an unfolded state as a reference plane, the projection of the top wall on the reference plane covers the projection of the edge of the bending area on the reference plane. The edge of the flexible bending area is shielded by the cover to reduce the risk that the flexible display screen is separated from the support surface of the rotating shaft mechanism due to external force acting on the edge, thereby improving the reliability of the flexible display screen. By arranging the end cover on the end face of the protruding portion, the design requirement for the thickness of the protruding portion can be reduced. Therefore, the protruding portion can be fixedly connected to the cover 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.

[0036] In some embodiments, the cover can further include a first side wall and a second side wall. The first side wall and the second side wall are respectively connected to the two ends of the top wall and are respectively fixedly connected to the end portion, thereby improving the connection reliability of the cover and the end portion.

[0037] In an implementation, the first side wall and the second side wall can be respectively connected to the two side faces of the protruding portion. In this way, not only can the contact area between the cover and the end portion be increased and the connection strength of the cover and the end portion be improved, but also the cover can be positioned by the protruding portion, thereby improving the assembly precision of the cover in the electronic device.

[0038] In some embodiments, the two side faces of the end portion respectively have a first limiting step and a second limiting step. The end of the first side wall away from the top wall has a first hook, which is hung on the step face of the first limiting step. The end of the second side wall away from the top wall has a second hook, which is hung on the step face of the first limiting step and the step face of the second limiting step. By using the cooperation between the first hook and the first limiting step and the cooperation between the second hook and the second limiting step, the connection reliability of the cover and the base can be further improved.

[0039] In some embodiments, an extension wall is provided on the side of the top wall facing away from the end cap. The edge of the extension wall extends beyond the raised portion and extends away from the end cap. The arrangement direction of the first and second shells of the electronic device in the unfolded state is defined as a second direction. The width of the extension wall along the second direction is less than the width of the top wall along the second direction. The projection of the extension wall on a reference plane partially overlaps the projection of the edge of the flexible display on the reference plane. Because the width of the extension wall is relatively small, interference between the extension wall and the bent flexible display can be avoided when the electronic device is in the closed state, thereby further improving the reliability of the flexible display.

[0040] In some embodiments, the top wall may be provided with a positioning groove, the raised surface of the raised portion may be provided with a groove, and the bottom of the groove may be provided with a positioning column. The positioning column may be inserted into the positioning groove to utilize the plug-in relationship between the positioning column and the positioning groove to position the cover body, thereby improving the installation position accuracy of the cover body.

[0041] In some embodiments, each shielding assembly may further include a guide post and a block. The top wall and at least a portion of the end portion are spaced apart, and the guide post is disposed between the top wall and the end portion; the block and the guide post are located on the same side of the top wall, and the block is made of a flexible material. The block cover is disposed on the edge of the flexible display screen to shield the edge of the bending zone, thereby reducing the risk of the flexible display screen being disengaged from the hinge mechanism due to external forces on the edge, and improving the reliability of the flexible display screen. The block includes a sliding portion disposed opposite to the base, and the sliding portion is provided with a through hole. The block can be sleeved on the guide post through the through hole, so that the block can slide along the guide post in the thickness direction of the electronic device.

[0042] When the electronic device is in the expanded state, the sliding portion is located at one end of the guide column near the top wall. During the process of switching the electronic device from the expanded state to the closed state, the block can bend along with the flexible display screen. Since the sliding portion has the freedom of movement in the thickness direction of the electronic device, the sliding portion slides along the guide column toward the direction near the end. In this way, the block can achieve a smooth transition at all positions during the bending process, and the block can achieve a relatively large bending radius, thereby releasing the bending stress of the block, reducing the risk of plastic deformation of the block due to dead bending, and improving the structural reliability of the block. After the electronic device is switched to the closed state, the sliding portion is located at one end of the guide column near the end. During the process of switching the electronic device from the closed state to the expanded state, as the flexible display screen flattens, the block also flattens synchronously, and the sliding portion slides along the guide column toward the direction near the top wall, so that after the electronic device is switched to the expanded state, the block returns to its undeformed natural state.

[0043] In some embodiments, the guide post may be fixed to the top wall so that the guide post can be reliably positioned between the top wall and the end portion. The gap between the end of the guide post facing away from the top wall and the end portion is smaller than the thickness of the stopper, thereby reducing the risk of the stopper being separated from the guide post due to the gap between the guide post and the end portion, thereby improving the movement reliability of the stopper.

[0044] In some embodiments, the guide post may be fixed to the end portion so that the guide post can be reliably positioned between the top wall and the end portion. The gap between the end of the guide post facing away from the end portion and the top wall is smaller than the thickness of the stopper, thereby reducing the risk of the stopper being separated from the guide post due to the gap between the guide post and the top wall, thereby improving the movement reliability of the stopper.

[0045] In some embodiments, the raised surface of the raised portion is provided with a groove, and the guide column can be provided between the top wall and the bottom of the groove, so that the guide column does not occupy additional space of the base in the first direction, thereby helping to further reduce the axial length of the base.

[0046] In some embodiments, the side of the sliding portion facing the end cap has an extension block, and at least a portion of the through hole is disposed on the extension block. When the shielding assembly is assembled, the extension block can extend into the groove to facilitate sliding engagement with the guide post in the groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] In the embodiment of the present application, the electronic device 1000 may be an inward-folding electronic device. When the inward-folding electronic device 1000 is in a closed state, the flexible display screen 400 is located on the inner side of the electronic device 1000. Figure 1 shows the relative positional relationship between the hinge mechanism 300 and the two housings when the inward-folding electronic device 1000 is in the closed state. Of course, in other embodiments, the electronic device 1000 may also be an outward-folding electronic device, and when the outward-folding electronic device 1000 is in the closed state, the flexible display 400 is located on the inner side of the electronic device 1000.

[0080] Figure 3 for Figure 1 FIG1 is a schematic diagram of a partially exploded structure of the electronic device 1000 in an unfolded state. Figure 3 As shown, in the embodiment of the present application, the first housing 100, the second housing 200, and the hinge mechanism 300 each have a support surface facing the flexible display 400. The flexible display 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. When the electronic device 1000 is in the unfolded state, 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 providing a flat support for the flexible display 400.

[0081] In some embodiments, the first housing 100 may include a first middle frame and a first rear shell, and the second housing 200 may include a second middle frame and a second rear shell, wherein the first middle frame is fixedly connected to the first rear shell and may form an accommodation space, and the second middle frame is fixedly connected to the second rear shell and may form an accommodation space. The surface of the first middle frame facing away from the first rear shell can serve as the support surface 100a of the first housing 100 for supporting the flexible display 400, and the surface of the first rear shell facing away from the middle frame can serve as the exterior surface of the first housing 100. Similarly, the surface of the second middle frame facing away from the second rear shell can serve as the support surface 200a of the second housing 200 for supporting the flexible display 400, and the surface of the second rear shell facing away from the second middle frame can serve as the exterior surface of the second housing 200.

[0082] The electronic device 1000 may also be mounted within the housing space of the first housing 100 and / or the second housing 200, including electronic components such as a circuit board, a battery, a receiver, a speaker, and a camera. The circuit board may integrate electronic components such as the electronic device's main controller, storage unit, antenna module, and power management module, while the battery may power the flexible display, circuit board, receiver, speaker, and camera.

[0083] The electronic device 1000 is composed of Figure 1 The closed state shown to Figure 2 The process of the expanded state shown, or by Figure 2 Shown expanded state to Figure 1 The process of the closed state shown is the process in which the first shell 100 and the second shell 200 rotate away from each other or relative to each other around the hinge mechanism 300. During the above process, the flexible display screen 400 can be bent or flattened as the first shell 100 and the second shell 200 rotate.

[0084] refer to Figure 3In the embodiment of the present application, the flexible display screen 400 includes a first fixed area 410, a second fixed area 420, and a bending area 430, and the bending area 430 is 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, and 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, and 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.

[0085] It can be understood that in some other embodiments of the present application, the electronic device 1000 can further include 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 one 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.

[0086] 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; and 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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".

[0091] 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 part of the flexible display screen 400 covered by the first edge cover 500 and the second edge cover 600 will not affect the display of the flexible display screen 400.

[0092] 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 coincide 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 coincide 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.

[0093] Continuing to refer to Figure 3As shown, 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 covers the edge of the first fixed area 410, and the second retaining wall 520 surrounds 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 covers the edge of the second fixed area 420, and the fourth retaining wall 620 surrounds the side of the second fixed area 420.

[0094] 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.

[0095] As described above, in the first direction x, the two side edges of the bending area 430 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 430 in different use states of the electronic device 1000. At present, the shielding structure used in the electronic device is relatively fixed in the thickness direction of the electronic device 1000, and the relative distance between the shielding structure and the bending area of the flexible display screen 400 is basically unchanged during the unfolding or closing process of the electronic device 1000, which leads to a relatively small bending degree of the shielding structure. On the one hand, this will hinder the flexible display screen 400 from forming a water drop shape, and is easy to generate a force on the flexible display screen 400 at the bending position, increasing the risk of damaging the flexible display screen 400, and on the other hand, the shielding structure is easy to appear dead folding after bending due to the too small bending angle, leading to plastic deformation of the shielding structure and affecting the appearance effect thereof.

[0096] Therefore, the application provides a shielding assembly which can shield the edge of the bending area 430 and increase the bending radius of part of the structure of the shielding assembly when the electronic device 1000 is in the closed state, thereby reducing the risk of dead folding and improving the reliability of the shielding assembly and the flexible display screen 400, and improving the appearance quality of the electronic device 1000. Next, the structure of the shielding assembly 700 and its application in the electronic device 1000 will be described.

[0097] It should be noted that in the embodiments of the application, the electronic device can include two shielding assemblies 700, which are respectively arranged at the two ends of the hinge mechanism 300. Referring to FIG. 7A, Figure 3 As shown in FIG. 7A, along the first direction x, the base 310 of the hinge mechanism 300 includes two oppositely arranged end portions 311, which are the two ends of the hinge mechanism 300 beyond the flexible display screen 400, and the two shielding assemblies 700 are arranged at the two end portions, respectively.

[0098] Figure 4 FIG. 7B shows a partial exploded view of one of the shielding assemblies 700 and the corresponding end portion 311 of the electronic device 1000 in an unfolded state, Figure 4 FIG. 7B shows a partial exploded view of one of the shielding assemblies 700 and the corresponding end portion 311 of the electronic device 1000 in an unfolded state, Figure 4 As shown in FIG. 7A, the shielding assembly 700 can include a cover 710, a guide column 720 and a blocking block 730. The cover 710 is fixed to the end portion 311, and the cover 710 includes a top wall 711 which is arranged on the side of the end portion 311 facing the side of the flexible display screen, and the top wall 711 has a gap with at least part of the area of the end portion 311. The guide column 720 is arranged between the top wall 711 and the end portion 311. It is easy to understand that the guide column 720 is arranged along the thickness direction of the electronic device 1000. The blocking block 730 is located on the same side of the top wall 711 as the guide column 720, and the blocking block 730 is arranged on the edge of the flexible display screen 400. The blocking block 730 includes a sliding portion 731 which is located opposite to the base 310 along the thickness direction of the electronic device 1000, and 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, and the blocking block 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 blocking block 730 can slide along the guide column 720 in the thickness direction of the electronic device 1000, so that the constraint of the blocking block 730 in the thickness direction of the electronic device 1000 is released.

[0099] In the embodiments of the present application, the stopper 730 can be made of a flexible material. For example, the material of the stopper 730 includes but is not limited to thermoplastic urethane (TPU). During the switching of the electronic device 1000 from the unfolded state to the closed state, the stopper 730 can be bent along with the flexible display screen 400. During the switching of the electronic device 1000 from the closed state to the unfolded state, the stopper 730 can gradually flatten along with the flexible display screen 400. Therefore, in the unfolded state, the closed state and the intermediate state of the electronic device 1000, the stopper 730 can shield the edge of the flexible display screen 400 exposed to the outside, thereby reducing the risk of the flexible display screen 400 being separated from the support surface 300a of the rotating shaft mechanism 300 due to the edge being subjected to an external force, and improving the reliability of the flexible display screen 400.

[0100] In combination Figure 4 As shown in FIG. 7, 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. Along the second direction y, one end of the stopper 730 can extend at least to the connection position of the rotating shaft mechanism 300 and the first housing 100, and the other end of the stopper 730 can extend at least to the connection position of the rotating shaft mechanism 300 and the second housing 200. In this way, the stopper 730 of the two shielding assemblies 700 and the first stopper 500 and the second stopper 600 can form a ring structure, thereby completely shielding the edge of the flexible display screen 400, and further improving the reliability of the flexible display screen 400.

[0101] In a specific implementation, the stopper 730 further includes a first part 732 and a second part 733. Along the second direction y, the first part 732 and the second part 733 are respectively connected to the two sides of the sliding part 731. Along the thickness direction of the electronic device 1000, the first part 732 is opposite to the first housing 100 in position, and the second part 733 is opposite to the second housing 200 in position. The end of the first part 732 away from the sliding part 731 is arranged between the first stopper 500 and the flexible display screen 400, and the end of the second part 733 away from the sliding part 731 is arranged between the second stopper 600 and the flexible display screen 400. That is, the two ends of the stopper 730 are fixed and hidden by the first stopper 500 and the second stopper 600. In this way, on the one hand, the appearance of the electronic device 1000 can be improved, and on the other hand, the limiting effect of the first stopper 500 and the second stopper 600 can be used to reduce the risk of the two ends of the stopper 730 being raised relative to the flexible display screen 400, and improve the use reliability of the electronic device 1000.

[0102] Figure 5 For Figure 4 FIG. 7 is another perspective view of the electronic device 1000 in the unfolded state.Figure 4 and Figure 5 As shown in FIG. 7, in the embodiment, the cover 710 can further include an end cover 712, which is connected to one end of the top wall 711 away from the stopper 730 along the first direction x, and the end cover 712 is fixedly connected with the end portion 311, so that the cover 710 is fixedly connected with the end portion 311 as a whole through the end cover 712. In one implementation, each of the two end portions 311 of the base 310 includes a protruding portion 3111 arranged towards the side where the flexible display screen 400 is located, and each protruding portion 3111 includes an end surface 3111a facing away from the other protruding portion.

[0103] In some embodiments, for each shielding assembly 700, the end cover 712 of the cover 710 can be arranged on the end surface 3111a of the protruding portion 3111 of the corresponding end portion. Exemplarily, the end cover 712 and the end surface 3111a of the protruding portion 3111 can be fixedly connected by bonding or welding. This design of fixing the end cover 712 on one side of the protruding portion 3111 does not have a high requirement on the thickness (the dimension of the protruding portion 3111 along the first direction) of the protruding portion 3111, so the protruding portion 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.

[0104] In some other embodiments, the protruding portion 3111 is 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 protruding portion 3111 can be fixedly connected.

[0105] Continuing to refer to Figure 4 and Figure 5 , the cover 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 311, so that the cover 710 can also be fixedly connected with the end portion 311 as a whole by using the first side wall 713 and the second side wall 714. In a specific implementation, the cover 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 710 and the end portion 311.

[0106] In an embodiment, the connection position of the first side wall 713 and the top wall 711, and the connection position of the second side wall 714 and the top wall 711 can be transitioned through a rounded corner to reduce the risk of the cover being impacted. The size of the rounded corner can be designed according to the size 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 rounded corner connecting the first side wall 713 and the top wall 711 can be regarded as the dividing line of the first side wall 713 and the top wall 711, and the position of the center line of the rounded corner connecting the second side wall 714 and the top wall 711 can be regarded as the dividing line of the second side wall 714 and the top wall 711.

[0107] In addition, the first side wall 713 and the second side wall 714 can also be connected with the side surface of the protruding part 3111 in the second direction y, respectively. The specific connection manner includes but is not limited to bonding. In this way, not only can the contact area of the cover 710 and the end part 311 be further increased, and the connection strength of the cover 710 and the end part 311 be improved, but also the cover 710 can be positioned in the second direction by using the protruding part 3111, and the assembly precision of the cover 710 in the electronic device 1000 can be improved.

[0108] In the embodiment of the present application, the cover 710 can be an integral structure. In one implementation, the cover 710 can be obtained by metal injection molding (MIM). Metal injection molding can obtain a cover 710 with high dimensional accuracy, thereby facilitating the cooperation of the shielding assembly and the base. In addition, the structure of the cover 710 obtained by metal injection molding is uniform at each position, and the relative density is high, so it has high strength and can achieve better protection effect on the edge of the flexible display screen 400. Exemplarily, the material of the cover includes aluminum alloy, stainless steel, etc.

[0109] In some embodiments, the two sides of the end part can respectively have a first limiting step and a second limiting step, and the first limiting step and the second limiting step respectively have a step surface facing away from the side where the flexible display screen is located. The end of the first side wall away from the top wall has a first hook, and the end of the second side wall away from the top wall has a second hook. The first hook is hung on the step surface of the first limiting step, and the second hook is hung on the step surface of the second limiting step. By using the cooperation relationship between the first hook and the first limiting step and the cooperation relationship between the second hook and the second limiting step, the connection reliability of the cover and the base can be further improved.

[0110] In an embodiment of the present application, the raised surface of the raised portion 3111 is provided with a groove 31111, and the guide column 720 can be located between the top wall 711 and the bottom of the groove 31111, that is, the guide column 720 and the raised portion 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.

[0111] In some embodiments, the sliding portion 731 may have an extension block 7312 on a side facing the end cap 712, and at least a portion of the through hole 7311 is disposed on the extension block 7312. The width of the extension block 7312 along the second direction y is smaller than the width of the groove 31111 along the second direction y. When the shielding assembly 700 is assembled, the extension block 7312 may extend into the groove 31111 to facilitate sliding engagement with the guide post 720 within the groove 31111.

[0112] Please continue to refer to Figure 4 and Figure 5 In the embodiment of the present application, the guide post 720 can be fixed to the top wall 711 so that the guide post 720 can be reliably positioned between the top wall 711 and the end portion 311. In one implementation, the guide post 720 and the top wall 711 can be an integral structure, which can not only improve the overall structural strength of the cover 710, but also ensure the position accuracy of the guide post 720, thereby avoiding design tolerances and assembly tolerances caused by the separate processing and assembly of the guide post 720.

[0113] In addition, the end of the guide post 720 facing away from the top wall 711 and the end portion 311 may be in contact with each other or may be spaced apart, which is not limited in this application. It is worth mentioning that when the end of the guide post 720 facing away from the top wall 711 and the end portion 311 are spaced apart, the gap between the end of the guide post 720 facing away from the top wall 711 and the end portion 311 is smaller than the thickness of the stopper 730. Specifically, the gap between the end of the guide post 720 facing away from the top wall 711 and the end portion 311 is smaller than the thickness of the sliding portion 731, thereby reducing the risk of the sliding portion 731 detaching from the guide post 720 due to the gap between the guide post 720 and the end portion, thereby improving the movement reliability of the stopper 730.

[0114] Figure 6 for Figure 4 FIG1 is a schematic diagram of a partial cross-sectional structure of the electronic device 1000 in the unfolded state, Figure 7 for Figure 4 The partial cross-sectional structure diagram of the electronic device 1000 in the closed state is shown in FIG. Figure 6 and Figure 7As shown, in the unfolded state, the sliding part 731 is located at one end of the guide column 720 close to the top wall 711, and the sliding part 731 can be in contact with the top wall 711, for example. During the switching of the electronic device 1000 from the unfolded state to the closed state, as the flexible display 400 is bent, the stop block 730 is also bent synchronously. Based on the sliding fit relationship between the sliding part 731 and the guide column 720, the sliding part 731 has a movement freedom degree in the thickness direction of the electronic device 1000, so the sliding part 731 can slide along the guide column 720 towards the direction close to the end part 311. Compared with the design in the prior art in which the distance between the shielding structure and the bending area 430 of the flexible display 400 remains unchanged, in the present embodiment, the connection positions of the sliding part 731 and the first part 732 and the connection positions of the sliding part 731 and the second part 733 can all realize smooth transition, and the connection positions of the sliding part 731 and the first part 732 and the connection positions of the sliding part 731 and the second part 733 can all realize relatively large bending radii, so as to release the bending stress of the stop block 730, reduce the risk of plastic deformation of the stop block 730 due to dead folding, and improve the structural reliability of the stop block 730.

[0115] After the electronic device 1000 is switched to the closed state, the sliding part 731 is located at one end of the guide column 720 close to the end part, and the sliding part 731 can be in contact with the end part 311, for example. During the switching of the electronic device 1000 from the closed state to the unfolded state, as the flexible display 400 is flattened, the first part 732 and the second part 733 of the stop block 730 are also flattened relative to the sliding part 731, and the sliding part 731 slides along the guide column 720 towards the direction close to the top wall 711, so that the stop block 730 returns to the natural state of no deformation after the electronic device 1000 is switched to the unfolded state.

[0116] Figure 8 Another partial exploded view of an electronic device 1000 in an unfolded state is provided in an embodiment of the present application. Referring to Figure 8 As shown, in the present embodiment, the structural composition of the shielding assembly 700 is basically the same as that of the foregoing embodiments, except that the fixing manner of the guide column 720 is changed in the present embodiment. Specifically, the guide column 720 in the present embodiment is fixed to the end part 311. In one implementation, the guide column 720 and the end part 311 can be an integral structure, or in other words, the guide column 720 and the base 310 are an integral structure, which can not only improve the connection strength of the guide column 720 and the base 310, but 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.

[0117] In this embodiment, the end of the guide post 720 facing away from the end portion 311 may contact the top wall 711 or may be spaced apart therefrom, which is not a limitation in this application. In the case where the end of the guide post 720 facing away from the end portion is spaced apart from the top wall 711, the gap between the end of the guide post 720 facing away from the end portion 311 and the top wall 711 is smaller than the thickness of the stopper 730. Specifically, the gap between the end of the guide post 720 facing away from the end portion and the top wall 711 is smaller than the thickness of the sliding portion 731, thereby reducing the risk of the sliding portion 731 detaching from the guide post 720 due to the gap between the guide post 720 and the top wall 711, thereby improving the movement reliability of the stopper 730.

[0118] Figure 9 for Figure 8 FIG1 is a schematic diagram of a partial cross-sectional structure of the electronic device 1000 in the unfolded state, Figure 10 for Figure 8 The partial cross-sectional structure diagram of the electronic device 1000 in the closed state is shown in FIG. Figure 9 and Figure 10 As shown, when the electronic device 1000 is in the unfolded state, the sliding portion 731 is located at the end of the guide post 720 near the top wall 711. For example, the sliding portion 731 may contact the top wall 711. As the electronic device 1000 switches from the unfolded state to the closed state, as the flexible display 400 bends, the stopper 730 also bends synchronously. Based on the sliding fit between the sliding portion 731 and the guide post 720, the sliding portion 731 has the freedom to move in the thickness direction of the electronic device 1000. Therefore, the sliding portion 731 can slide along the guide post 720 toward the end 311. Compared with the design in the prior art in which the distance between the shielding structure and the bending zone of the flexible display remains unchanged, in this embodiment, the connection position between the sliding part 731 and the first part 732, and the connection position between the sliding part 731 and the second part 733 can both achieve a smooth transition, and the connection position between the sliding part 731 and the first part 732, and the connection position between the sliding part 731 and the second part 733 can both achieve a relatively large bending radius, thereby releasing the bending stress of the block 730, reducing the risk of plastic deformation of the block 730, and improving the structural reliability of the block 730.

[0119] After the electronic device 1000 switches to the closed state, the sliding portion 731 is located at the end of the guide post 720 near the end 311. For example, the sliding portion 731 may contact the end 311. During the process of switching the electronic device 1000 from the closed state to the expanded state, as the flexible display 400 flattens, the first portion 732 and the second portion 733 of the stopper 730 also flatten relative to the sliding portion 731. The sliding portion 731 then slides along the guide post 720 toward the top wall 711, so that after the electronic device 1000 switches to the expanded state, the stopper 730 returns to its undeformed natural state.

[0120] Figure 11 This is a partial exploded view of another electronic device 1000 provided in an embodiment of the present application in an unfolded state. Figure 11 As shown, in the embodiment of the present application, the structural composition of the shielding assembly 700 is basically the same as that of the aforementioned embodiment, except that, in the present embodiment, along the first direction x, the side of the stopper 730 close to the cover body 710 can be set beyond the side edge of the flexible display screen 400. In this case, the stopper 730 can also include a first limiting wall 734 and a second limiting wall 735, wherein the first limiting wall 734 is connected to the side of the first portion 732 that exceeds the side edge of the flexible display screen 400, and the first limiting wall 734 and the first portion 735 are connected. 732 is set at an angle. For example, the first limiting wall 734 and the first part 732 can be roughly perpendicular, and the first limiting wall 734 extends along the thickness direction of the electronic device 1000; similarly, the second limiting wall 735 is connected to the side of the second part 733 that extends beyond the side edge of the flexible display screen 400, and the second limiting wall 735 and the second part 733 are set at an angle. For example, the second limiting wall 735 and the second part 733 can be roughly perpendicular, and the second limiting wall 735 extends along the thickness direction of the electronic device 1000.

[0121] In the embodiment, the first limiting wall 734 can be arranged on the side edge of the first fixed area 410, and the second limiting wall 735 can be arranged on the side edge of the second fixed area 420. That is, the projection of the first limiting wall 734 on the first direction x at least partially overlaps the projection of the first fixed area 410 on the first direction x, and the projection of the second limiting wall 735 on the first direction x at least partially overlaps the projection of the second fixed area 420 on the first direction x. For example, the first limiting wall 734 can be located between the side edge of the first fixed area 410 and the second blocking wall 520, and the second limiting wall 735 can be located between the side edge of the second fixed area 420 and the fourth blocking wall 620. Based on the relative position relationship between the flexible display screen 400 and the first limiting wall 734 and the second limiting wall 735, the flexible display screen 400 can limit the first limiting wall 734 and the second limiting wall 735, reduce the risk of the first part 732 and the second part 733 sliding to the display area of the flexible display screen 400, improve the installation position accuracy of the blocking block 730, and avoid the blocking block 730 affecting the display effect of the flexible display screen 400.

[0122] In addition, in the embodiment, the guide column 720 can be fixed to the top wall 711 of the cover body 710 or the end portion 311 of the base 310, and the application does not limit this, and the specific fixing mode can be set according to the foregoing embodiments, which will not be repeated here.

[0123] Based on the same inventive concept, the embodiment of the application provides another electronic device 1000, which is shown in Figure 12 Figure 12 is a structural schematic view of the electronic device in an unfolded state. The electronic device 1000 can also include two blocking assemblies 700, which are respectively arranged on the two end portions 311 of the base to block the two side edges of the bending area 430 of the flexible display screen 400. In addition, in the electronic device 1000, the structures of the first shell 100, the second shell 200, the rotating shaft mechanism 300, the flexible display screen 400, etc. can be designed according to the foregoing embodiments, which will not be repeated here. The structure of the blocking assembly 700 and its application in the electronic device 1000 will be specifically described below.

[0124] Figure 13 is a structural schematic view of another electronic device 1000 provided by the embodiment of the application in an unfolded state, Figure 14 is Figure 13 is an exploded view of the blocking assembly in the electronic device shown in Figure 13 shows the position relationship between one of the blocking assemblies 700 and the corresponding end portion 311. For reference Figure 13 Figure 14 ​As shown, in the embodiments of the present application, the two ends 311 of the base 310 respectively include a protruding portion 3111 arranged towards 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. Each shielding assembly includes a cover body 710 fixed to the corresponding end 311, and the cover body 710 includes a top wall 711 and an end cover 712, wherein the end cover 712 can be arranged on the end face 3111a of the protruding portion 3111 of the corresponding end, the top wall 711 is connected with the end cover 712, and the top wall 711 is arranged on the protruding surface of the protruding portion 3111. A plane perpendicular to the thickness direction of the electronic device 1000 is defined as a reference plane, and the projection of the top wall 711 on the reference plane covers the projection of the edge of the flexible display screen 400 on the reference plane, for example, the projection of the top wall 711 on the reference plane can cover the projection of the edge of the bending area 430 of the flexible display screen 400 on the reference plane. Through this design, the edge of the flexible display screen 400 exposed to the outside can be shielded by the cover body 710, the risk that the flexible display screen 400 is separated from the support surface 300a of the rotating shaft mechanism 300 due to the edge being subjected to an external force can be reduced, and the reliability of the flexible display screen 400 can be improved.

[0125] In addition, by arranging the end cover 712 on the end face 3111a of the protruding portion 3111, the design requirement for the thickness (the size of the protruding portion 3111 in the first direction) of the protruding portion 3111 can be reduced, so that the protruding portion 3111 can be fixedly connected with the cover body 710 with a relatively small thickness, thereby helping to reduce the axial length of the base 310, and further the overall length of the electronic device 1000. Exemplarily, the end cover 712 and the end face 3111a of the protruding portion 3111 can be fixedly connected by bonding or welding.

[0126] In one implementation, the side of the top wall 711 facing away from the end cover 712 is provided with an extension wall 7111, and the width of the extension wall 7111 along the second direction y is smaller than the width of the top wall 711 along the second direction y. The edge of the extension wall 7111 extends in a direction away from the end cover 712 beyond the protruding portion 3111, and the projection of the extension wall 7111 on the reference plane covers the projection of the edge of the bending area 430 of the flexible display screen 400 on the reference plane. In this way, not only can the cover body 710 shield the edge of the flexible display screen 400 exposed to the outside, but also since the width of the extension wall 7111 is relatively small, when the electronic device is in the closed state, the extension wall 7111 can be prevented from interfering with the flexible display screen 400 in the bending state, thereby helping to further improve the reliability of the flexible display screen 400.

[0127] Continuing to refer to Figure 13 and Figure 14As shown, the cover body 710 can further include a first side wall 713 and a second side wall 714 connected to two sides of the top wall 711 along the second direction respectively, and the first side wall 713 and the second side wall 714 are fixedly connected with the end portion 311 respectively. 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 through a round corner 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, and the present application does not make any limitation thereon. 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 of 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 of the second side wall 714 and the top wall 711. In an implementation, the first side wall 713 and the second side wall 714 can be further connected with two side surfaces of the protruding portion 3111 along the second direction y respectively. In this way, not only can the contact area of the cover body 710 and the end portion 311 be further increased, and the connection strength of the cover body 710 and the end portion 311 be improved, but also the protruding portion 3111 can be used to position the cover body 710 in the second direction, and the assembly precision of the cover body 710 in the electronic device 1000 can be improved.

[0128] Please continue to refer to 13 and Figure 14 In the embodiment of the present application, along the second direction y, the two sides of the end portion 311 are respectively provided with a first limiting step 3112 and a second limiting step 3113, and the first limiting step 3112 and the second limiting step 3113 respectively have a step surface facing away from the side where the flexible display screen is located. An end of the first side wall 713 away from the top wall 711 is provided with a first hook 7131, and an end of the second side wall 714 away from the top wall 711 is provided with a second hook 7141, the first hook 7131 is hung on the step surface of the first limiting step 3112, and the second hook 7141 is hung on the step surface of the second limiting step 3113. By using the cooperation relationship between the first hook 7131 and the first limiting step 3112 and the cooperation relationship between the second hook 7141 and the second limiting step 3113, the connection reliability of the cover body 710 and the base can be further improved.

[0129] Figure 15 A structural schematic diagram of the cover body 710 provided in the embodiment of the present application is shown. Please refer to Figure 14 and Figure 15As shown, in the application embodiment, the convex surface of the convex part 3111 is provided with a groove 31111, the groove bottom of the groove 31111 is provided with a positioning column 31112, and correspondingly, the top wall 711 is provided with a positioning groove 7112. When the cover body 710 is installed at the end, the positioning column 31112 can be inserted into the positioning groove 7112, and by the plug-in relationship between the two, on the one hand, the cover body 710 can be positioned, improving the installation position accuracy of the cover body 710, and on the other hand, the positioning column 31112 and the positioning groove 7112 can be made to have an interference fit through reasonable size design, thereby improving the connection reliability of the cover body 710 and the convex part 3111.

[0130] It should be understood that the above-mentioned positioning column 31112 provided on the top wall 711 and cooperating with the convex part 3111 is not the only implementation form of the shielding assembly 700. In some other embodiments of the present application, the shielding assembly 700 can also be implemented in other forms, and the cover body 710 can also correspondingly adopt a structure design without the positioning column 31112. For example, in some embodiments, the shielding assembly can also include a guide column and a stopper. The guide column is arranged between the top wall and the end, and the guide column is arranged in the thickness direction of the electronic device. In the first direction, the stopper is located on the side of the cover body close to the flexible display screen, and the stopper is arranged on the edge of the flexible display screen. In addition, the stopper includes a sliding part, which is opposite to the base position in the thickness direction of the electronic device. The sliding part is provided with a through hole, the stopper can be sleeved on the guide column through the through hole, and the through hole and the guide column are in clearance fit. Therefore, the stopper can slide along the guide column in the thickness direction of the electronic device.

[0131] In a specific implementation, the stopper can be made of flexible material. During the process of switching the electronic device from the unfolded state to the closed state, the stopper can bend with the flexible display screen. During the process of switching the electronic device from the closed state to the unfolded state, the stopper can gradually flatten with the flexible display screen. Therefore, in the unfolded state, the closed state and the intermediate state of the electronic device, the stopper can shield the edge of the flexible display screen exposed to the outside. Combined with the shielding effect of the cover body, the reliability of the flexible display screen can be further improved.

[0132] In some embodiments, the stopper further includes a first part and a second part, which are respectively connected to the two sides of the sliding part in the second direction. The end of the first part away from the sliding part is arranged between the first stop edge and the flexible display screen, and the end of the second part away from the sliding part is arranged between the second stop edge and the flexible display screen. That is, the two ends of the stopper are fixed and hidden by the first stop edge and the second stop edge respectively. In this way, on the one hand, the appearance of the electronic device can be improved, and on the other hand, the two ends of the stopper can be fixed relative to the flexible display screen, reducing the risk of the two ends of the stopper being raised relative to the display screen, and improving the use reliability of the electronic device.

[0133] In some embodiments, along the first direction, the side of the block close to the cover can be arranged beyond the edge of the flexible display screen. In this case, the block can further include a first limiting wall and a second limiting wall, wherein the first limiting wall is connected to the side of the first portion beyond the edge of the side surface of the flexible display screen, the first limiting wall is arranged at an angle with the first portion, for example, the first limiting wall can be substantially perpendicular to the first portion, and the first limiting wall extends along the thickness direction of the electronic device; similarly, the second limiting wall is connected to the side of the second portion beyond the edge of the side surface of the flexible display screen, and the second limiting wall is arranged at an angle with the second portion, for example, the second limiting wall can be substantially perpendicular to the second portion, and the second limiting wall extends along the thickness direction of the electronic device. The projection of the first limiting wall in the first direction at least partially overlaps the projection of the flexible display screen in the first direction, or it can be understood that the first limiting wall is located on one side of the flexible display screen, and similarly, the projection of the second limiting wall in the first direction at least partially overlaps the projection of the flexible display screen in the first direction, that is, the second limiting wall is located on one side of the flexible display screen. By the relative position relationship between the flexible display screen and the first limiting wall and the second limiting wall, the flexible display screen can limit the first limiting wall and the second limiting wall, reduce the risk of the first portion and the second portion slipping to the display area of the flexible display screen, improve the installation position accuracy of the block, and avoid the block affecting the display effect of the flexible display screen.

[0134] In some embodiments, the guide column can be located between the top wall and the groove bottom, that is, the guide column and the protruding portion are stacked along the thickness of the electronic device. Through this design, the guide column does not occupy additional space of the base in the first direction, thereby helping to further reduce the axial length of the base.

[0135] In some embodiments, the side of the sliding portion facing the cover can have an extension block, and at least part of the through hole is arranged on the extension block. Along the second direction, the width of the extension block is less than the width of the groove, and when the shielding assembly is assembled, the extension block can extend into the groove to facilitate the sliding fit with the guide column in the groove.

[0136] In some embodiments, the guide column is fixed to the top wall, so that the guide column can be reliably positioned between the top wall and the end portion. For example, the guide column and the top wall can be an integral structure. In addition, the end portion and the end of the guide column away from the top wall can be in contact with each other or can be spaced apart. In the case where the end of the guide column away from the top wall and the end portion are spaced apart, the gap between the end of the guide column away from the top wall and the end portion is less than the thickness of the block, specifically, the gap between the end of the guide column away from the top wall and the end portion is less than the thickness of the sliding portion, so as to reduce the risk of the sliding portion deviating from the guide column between the guide column and the end portion, and improve the movement reliability of the block.

[0137] In some other embodiments, the guide post can be fixed to the end so that the guide post can be reliably positioned between the top wall and the end. For example, the guide post and the end can be an integral structure. In addition, the end of the guide post facing away from the end and the top wall can be in contact with each other, or can be spaced apart. In the case where the end of the guide post facing away from the end and the top wall are spaced apart, the gap between the end of the guide post facing away from the end and the top wall is smaller than the thickness of the block. Specifically, the gap between the end of the guide post facing away from the end and the top wall is smaller than the thickness of the sliding portion, so as to reduce the risk of the sliding portion detaching from the guide post due to the gap between the guide post and the top wall, thereby improving the movement reliability of the block.

[0138] Based on the same inventive concept, the present application provides another electronic device, referring to Figure 16 As shown, Figure 16 : is a schematic diagram of the structure of the electronic device 1000 in the unfolded state. The electronic device 1000 can also include two shielding components 700, which are respectively arranged at the two ends 311 of the base to shield the two side edges of the bending area 430 of the flexible display 400. In addition, in the electronic device 1000, the structures of the first shell 100, the second shell 200, the hinge mechanism 300, the flexible display 400, etc. can be designed with reference to the above embodiments and will not be repeated here. The structure of the shielding component 700 and its application in the electronic device 1000 will be described in detail below.

[0139] Figure 17 for Figure 16 The electronic device 1000 is shown in a partially exploded view from one perspective in the unfolded state. Figure 17 As shown, in the embodiment of the present application, the shielding assembly 700 includes a cover 710 and a stopper 730, wherein the cover 710 is fixed to the end 311, and the cover 710 includes a top wall 711, which is provided on the side of the end 311 facing the flexible display 400. The stopper 730 is fixedly connected to the top wall 711 and covers the edge of the flexible display 400. The stopper 730 can be made of a flexible material, and illustratively, the stopper 730 can be a polyimide (PI) sheet or a steel sheet. During the process of switching the electronic device 1000 from the unfolded state to the closed state, the block 730 can bend along with the flexible display screen 400. During the process of switching the electronic device 1000 from the closed state to the unfolded state, the block 730 can gradually flatten along with the flexible display screen 400. Therefore, when the electronic device 1000 is in the unfolded state, the closed state and the intermediate state, the block 730 can block the exposed edge of the flexible display screen 400, thereby reducing the risk of the flexible display screen 400 being out of contact with the support surface of the hinge mechanism 300 due to the action of external force on the edge, thereby improving the reliability of the flexible display screen 400.

[0140] In some embodiments, the shielding assembly 700 can further include a limiting piece 740, and the top wall 711, the block 730, and the limiting piece 740 are arranged in sequence along the thickness direction of the electronic device 1000, and the limiting piece 740 can fix the block 730 to the top wall 711. In a specific implementation, the block 730 is provided with a positioning hole 736, and the limiting piece 740 is provided with a fixing column 741 on the side facing the block 730. When the cover 710, the block 730, and the limiting piece 740 are assembled, the fixing column 741 can pass through the positioning hole 736 and be fixedly connected to the top wall 711, so as to fix the block 730 to the top wall 711. Exemplarily, the limiting piece 740 can be but is not limited to metal or soft rubber material, and the limiting piece 740 can be fixedly connected to the top wall 711 by welding or bonding.

[0141] Figure 18 For Figure 17 the shielding assembly 700 in the assembled state is shown. Referring to Figure 17 and Figure 18 together, in the embodiment, the block 730 can include a fixed part 737, and the fixed part 737 is opposite to the base 310 in the thickness direction of the electronic device 1000. When the block 730 is fixedly connected to the top wall 711, the fixed part 737 can be connected to the top wall 711. It can be easily understood that, in the case where the shielding assembly 700 includes the limiting piece 740, the positioning hole 736 of the block 730 can be arranged on the fixed part 737, so that the fixed column 741 of the limiting piece 740 can pass through the positioning hole 736 and fix the fixed part 737 to the top wall 711.

[0142] In addition, the block 730 can further include a first part 732 and a second part 733, and the arrangement direction of the first shell 100 and the second shell 200 is defined as the second direction y. Along the second direction y, the first part 732 and the second part 733 are respectively connected to the two sides of the fixed part 737, and along the thickness direction of the electronic device 1000, the first part 732 is opposite to the first shell 100, and the second part 733 is opposite to the second shell 200. One end of the first part 732 away from the fixed part 737 is arranged between the first blocking edge 500 and the flexible display screen 400, and one end of the second part 733 away from the fixed part 737 is arranged between the second blocking edge 600 and the flexible display screen 400, that is, the two ends of the block 730 are fixed and hidden by the first blocking edge 500 and the second blocking edge 600. This can improve the appearance of the electronic device 1000, and on the other hand, the limiting effect of the first blocking edge 500 and the second blocking edge 600 can reduce the risk of the two ends of the block 730 being raised relative to the flexible display screen 400, and improve the use reliability of the electronic device 1000.

[0143] Figure 19 For Figure 17 An exploded view of the electronic device shown in FIG. 1 from another perspective. Referring to FIG. 1 and FIG. 2 together, Figure 17 and Figure 19 In the present embodiment, the cover 710 can further include an end cap 712, which is connected to the top wall 711 at an end thereof away from the stopper 730 along the first direction x, and the end cap 712 is fixedly connected to the end portion 311, so that the cover 710 is fixedly connected to the end portion 311 as a whole via the end cap 712. In one implementation, each of the two end portions 311 of the base 310 includes a protrusion 3111 arranged towards the side where the flexible display 400 is located, and each protrusion 3111 includes an end surface 3111a facing away from the other protrusion.

[0144] In some embodiments, for each shielding assembly 700, the end cap 712 of the cover 710 can be arranged on the end surface 3111a of the protrusion 3111 of the corresponding end portion. Exemplarily, the end cap 712 and the end surface 3111a of the protrusion 3111 can be fixedly connected by bonding or welding. Such a design of fixing the end cap 712 to one side of the protrusion 3111 does not have a high requirement on the thickness (the dimension of the protrusion 3111 along the first direction) of the protrusion 3111, so the protrusion 3111 can be implemented with a relatively small thickness to facilitate the fixed connection with the end cap 712, thereby helping to reduce the axial length of the base 310, and further reducing the overall length of the electronic device 1000.

[0145] In some other embodiments, the protrusion 3111 is provided with a mounting groove, and the end cap 712 can be inserted into the mounting groove, so that the fixed connection between the end cap 712 and the protrusion 3111 can also be achieved.

[0146] In some embodiments, the cover 710 can further include a first side wall 713 and a second side wall 714, which are respectively connected to the top wall 711 at two sides thereof along the second direction y, and the first side wall 713 and the second side wall 714 are respectively fixedly connected to the end portion 311, so that the cover 710 can also be fixedly connected to the end portion 311 as a whole via the first side wall 713 and the second side wall 714. In a specific implementation, the cover 710 can include both the first side wall 713 and the second side wall 714 and the end cap 712, so as to improve the connection reliability between the cover 710 and the end portion 311.

[0147] In addition, the first side wall 713 and the second side wall 714 can also be connected with the side surface of the protruding part 3111 in the second direction y, for example, by adhesive connection. In this way, not only can the contact area between the cover body 710 and the end part 311 be further increased, and the connection strength between the cover body 710 and the end part 311 be improved, but also the cover body 710 can be positioned in the second direction by using the protruding part 3111, and the assembly precision of the cover body 710 in the electronic device 1000 can be improved.

[0148] In some embodiments, the side of the top wall 711 away from the end cover 712 is provided with an extension wall 7111, and the width of the extension wall 7111 in the second direction y is less than the width of the top wall 711 in the second direction y. The projection of the extension wall 7111 in the first direction x covers part of the projection of the fixing part 737 in the first direction x, and the fixing part 737 can be fixed to the extension wall 7111 by the limiting piece 740. In addition, since the width of the extension wall 7111 is relatively small, when the electronic device is in the closed state, the extension wall 7111 can be prevented from interfering with the flexible display screen in the bent state, thereby helping to further improve the reliability of the flexible display screen.

[0149] In the embodiments of the present application, other structural designs of the cover body and the stop block can refer to the descriptions of the foregoing embodiments, which will not be repeated here.

[0150] The above is only a specific implementation manner 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 changes or replacements within the technical range disclosed in 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.
