[0002] The present application claims priority to the Chinese patent application No. 202410465475.1, filed on April 17, 2024, and entitled "A shielding assembly and electronic device", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

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

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

[0005] The edge of the flexible display screen is generally covered by a protective structure to protect the edge of the flexible display screen from wear and collision. In order to avoid the protective structure hindering the bending or flattening movement of the flexible display screen, the protective structure usually does not extend to the bending area of the flexible display screen. If the edge of the bending area of the flexible display screen is exposed, on the one hand, it will affect the appearance quality of the electronic device, and on the other hand, the flexible display screen is also easy to be out of contact with the 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

[0006] The present application provides a shielding assembly and 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.

[0007] 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 blocking block. 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 blocking block is located on the same side of the top wall as the guide column, and the blocking block is made of flexible material. The blocking block is used to cover the edge of the flexible display screen, and the blocking block includes a sliding part. The sliding part is provided with a through hole, and the blocking block can be sleeved on the guide column through the through hole, so that the blocking block can slide along the guide column.

[0008] 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.

[0009] 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 by the gap between the guide column and the end portion, and improve the movement reliability of the blocking block.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] In some embodiments, the sliding part has an extension block on the side thereof facing the end cap, at least part of the through hole being arranged in the extension block to facilitate assembly of the sliding part, the guide column and the cover.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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 a degree of 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 over-bending, 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 flattens, the blocking piece also flattens synchronously, 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.

[0021] 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.

[0022] 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.

[0023] 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 stopper, so as to reduce the risk of the stopper being separated from the guide column by the gap between the guide column and the top wall, and improve the movement reliability of the stopper.

[0024] 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.

[0025] In some embodiments, the stopper further includes a first portion and a second portion, the first portion and the second portion are respectively connected to 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 stopper being raised relative to the flexible display screen, and improve the use reliability of the shielding assembly.

[0026] In some embodiments, the stopper further includes a first limiting wall and a second limiting wall. In the first direction, the side of the stopper 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 stopper, and avoid the influence of the stopper on the display effect of the flexible display screen.

[0027] In some embodiments, the cover body further includes 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.

[0028] 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.

[0029] Exemplarily, the end cover and the end face of the protrusion can be fixedly connected by bonding or welding.

[0030] 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.

[0031] 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.

[0032] 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 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] In some embodiments, 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.

[0040] 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.

[0041] In some embodiments, the top wall is provided with an extension wall on the side away from the end cover, the edge of the extension wall extends beyond the protrusion and extends away from the end cover, the arrangement direction of the first housing and the second housing 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 smaller than the width of the top wall along the second direction, and the projection of the extension wall on the reference plane covers the projection of the edge of the flexible display screen on the reference plane. Since the width of the extension wall is relatively small, when the electronic device is in the closed state, interference between the extension wall and the flexible display screen in the bent state can be avoided, thereby further improving the reliability of the flexible display screen.

[0042] In some embodiments, the top wall can be provided with a positioning groove, the protruding surface of the protrusion is provided with a recess, the groove bottom of the recess is provided with a positioning column, and the positioning column can be inserted into the positioning groove to position the cover body by the insertion relationship between the positioning column and the positioning groove, thereby improving the installation position accuracy of the cover body.

[0043] In some embodiments, each shielding assembly can further include a guide column and a stopper. The top wall is spaced apart from at least part of the end portion, and the guide column is arranged between the top wall and the end portion. 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 covers the edge of the flexible display screen to shield the edge of the bending area, thereby reducing the risk of the flexible display screen being separated from the rotating shaft mechanism due to external force acting on the edge and improving the reliability of the flexible display screen. The stopper includes a sliding portion opposite the base, and the sliding portion is provided with a through hole. The stopper can be sleeved on the guide column through the through hole, so that the stopper can slide along the guide column in the thickness direction of the electronic device.

[0044] 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. During the switching process of the electronic device from the unfolded state to the closed state, the stopper can be bent with the flexible display screen. Since the sliding portion has a degree of 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 stopper can smoothly transition at all positions during the bending process, and the stopper can achieve a relatively large bending radius, thereby releasing the bending stress of the stopper, reducing the risk of plastic deformation of the stopper due to dead folding, and improving the structural reliability of the stopper. 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. During the switching process of the electronic device from the closed state to the unfolded state, as the flexible display screen flattens, the stopper also flattens synchronously, and the sliding portion slides along the guide column towards the top wall. In this way, after the electronic device is switched to the unfolded state, the stopper returns to the natural state without deformation.

[0045] In some embodiments, the guide post can 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, so as to reduce the risk of the stopper being disengaged from the guide post by the gap between the guide post and the end portion, and improve the movement reliability of the stopper.

[0046] In some embodiments, the guide post can 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, so as to reduce the risk of the stopper being disengaged from the guide post by the gap between the guide post and the top wall, and improve the movement reliability of the stopper.

[0047] In some embodiments, the protruding surface of the protruding portion is provided with a groove, and the guide post can be arranged between the top wall and the groove bottom. In this way, the guide post does not occupy additional space of the base in the first direction, thereby helping to further reduce the axial length of the base.

[0048] In some embodiments, the sliding portion has an extension block facing the side surface 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, so as to facilitate the sliding fit with the guide post in the groove. BRIEF DESCRIPTION OF DRAWINGS

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

[0072] In the embodiment of the present application, the electronic device 1000 can be an inner-fold electronic device. In the closed state, the flexible display screen 400 is located on the inner side of the electronic device 1000. In FIG. 1, the relative position relationship between the hinge mechanism 300 and the two housings in the closed state of the inner-fold electronic device 1000 is shown. Of course, in some other embodiments, the electronic device 1000 can also be an outer-fold electronic device, and in the closed state, the flexible display screen 400 is located on the inner side of the electronic device 1000.

[0073] FIG. 3 is a partially exploded structural schematic diagram of the electronic device 1000 in the unfolded state according to an embodiment of the present application. Referring to FIG. 3, 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 arranged towards the flexible display screen 400, and the flexible display screen 400 can continuously cover the support surface 100a of the first housing 100, the support surface 200a of the second housing 200, and the support surface 300a of the hinge mechanism 300. In the unfolded state of the electronic device 1000, the support surface 100a of the first housing 100, the support surface 300a of the hinge mechanism 300, and the support surface 200a of the second housing 200 can be connected to form a flat support surface, thereby playing a role of flat support for the flexible display screen 400.

[0074] In some embodiments, the first housing 100 can include a first middle frame and a first back cover, and the second housing 200 can include a second middle frame and a second back cover, wherein the first middle frame is fixedly connected with the first back cover and can form a receiving space, and the second middle frame is fixedly connected with the second back cover and can form a receiving space. One side of the first middle frame away from the first back cover can serve as a support surface 100a of the first housing 100 for supporting the flexible display 400, and one side of the first back cover away from the middle frame can serve as an appearance surface of the first housing 100. Similarly, one side of the second middle frame away from the second back cover can serve as a support surface 200a of the second housing 200 for supporting the flexible display 400, and one side of the second back cover away from the second middle frame can serve as an appearance surface of the second housing 200.

[0075] In the receiving space of the first housing 100 and / or the second housing 200, an electronic device 1000 can also be installed with a circuit board, a battery, a microphone, a speaker, a camera, and other electronic components. The circuit board can integrate the main controller, the storage unit, the antenna module, the power management module, and other electronic components of the electronic device, and the battery can supply power to the flexible display, the circuit board, the microphone, the speaker, the camera, and other electronic components.

[0076] The process of the electronic device 1000 from the closed state shown in FIG. 1 to the unfolded state shown in FIG. 2, or the process from the unfolded state shown in FIG. 2 to the closed state shown in FIG. 1, is the process of the first housing 100 and the second housing 200 rotating around the rotation shaft mechanism 300 in opposite directions or relative directions, and in the above process, the flexible display 400 can be bent or flattened along with the rotation of the first housing 100 and the second housing 200.

[0077] Referring to FIG. 3, in the embodiment of the present application, the flexible display screen 400 comprises a first fixed area 410, a second fixed area 420 and a bending area 430, the bending area 430 being connected between the first fixed area 410 and the second fixed area 420. The first fixed area 410 is fixedly connected with the first shell 100, specifically, the first fixed area 410 can be fixedly connected with the support surface 100a of the first shell 100, and the connection manner includes but is not limited to bonding; the second fixed area 420 is fixedly connected with the second shell 200, specifically, the second fixed area 420 is fixedly connected with the support surface 200a of the second shell 200, and the connection manner includes but is not limited to bonding; the bending area 430 is opposite to the base 310 of the hinge mechanism 300. In the process of switching the electronic device 1000 from the unfolded state to the closed state, the bending area 430 of the flexible display screen 400 is bent, and the end of the first fixed area 410 away from the bending area 430 and the end of the second fixed area 420 away from the bending area 430 are close to each other; in the process of switching the electronic device 1000 from the closed state to the unfolded state, the bending area 430 of the flexible display screen 400 is gradually flattened, and the end of the first fixed area 410 away from the bending area 430 and the end of the second fixed area 420 away from the bending area 430 are away from each other.

[0078] It can be understood that in some other embodiments of the present application, the electronic device 1000 can further comprise a third shell connected between the first shell 100 and the second shell 200, and the first shell 100 and the third shell can be connected through a hinge mechanism 300, and the second shell 200 and the third shell can be connected through another hinge mechanism 300, and the electronic device 1000 in this form is a three-fold folding device.

[0079] In addition, in the embodiment of the present application, the electronic device 1000 can be unfolded and closed in a manual driving, electric driving or manual and electric hybrid driving manner. The manual driving manner means that the electronic device is unfolded and closed completely relying on the action force applied by the user; the electric driving manner means that the electronic device is unfolded and closed completely relying on the driving force output by the motor; the manual and electric hybrid driving means that the electronic device is unfolded and closed under the common driving of the action force applied by the user and the driving force output by the motor.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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".

[0084] It should be noted that the edge region of the flexible display screen 400 can also be referred to as a peripheral region, and the display region inside the peripheral region is a display region. The display region of the flexible display screen 400 can be used to display images, videos, and the like. The peripheral region is usually used to arrange wires, and therefore, the first edge cover 500 and the second edge cover 600 do not cover the display region of the flexible display screen 400 and do not affect the display of the flexible display screen 400.

[0085] In the embodiments of the present application, the first edge cover 500 and the second edge cover 600 can both have a structure similar to a U shape. The first edge cover 500 can cover the edges of the first fixed region 410, and the second edge cover 600 can cover the edges of the second fixed region 420. Alternatively, it can be understood that, in the unfolded state of the electronic device 1000, the projection of the first edge cover 500 on a reference plane perpendicular to the thickness direction of the electronic device 1000 is within the projection range of the first housing 100 on the reference plane, the projection of the second edge cover 600 on the reference plane is within the projection range of the second housing 200 on the reference plane, and the projection of the first edge cover 500 on the reference plane does not overlap with the projection of the rotation shaft mechanism 300 on the reference plane, and the projection of the second edge cover 600 on the reference plane does not overlap with the projection of the rotation shaft mechanism 300 on the reference plane. That is, neither the first edge cover 500 nor the second edge cover 600 covers the bending region of the flexible display screen 400, so as to avoid hindering the bending or unfolding movement of the flexible display screen 400.

[0086] With reference back to FIG. 3, in some embodiments, the first retaining edge 500 includes a first retaining wall 510 and a second retaining wall 520, which are arranged substantially perpendicularly, the first retaining wall 510 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.

[0087] 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.

[0088] 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 in the process of unfolding or closing 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 in the process of unfolding or closing 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 it 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. On the other hand, the shielding structure is prone to dead folding after bending due to the small bending angle, resulting in plastic deformation of the shielding structure and affecting the appearance effect.

[0089] 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.

[0090] 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. 3, 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 respectively arranged at the two end portions.

[0091] FIG. 4 is a partial exploded view of an electronic device 1000 provided by an embodiment of the application in an unfolded state from one perspective, which shows the positional relationship between one shielding assembly 700 and the corresponding end portion 311. Referring to FIG. 4, in the embodiments of the application, 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.

[0092] 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.

[0093] In combination with FIG. 4, 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 to at least the connection position of the rotating shaft mechanism 300 and the first housing 100, and the other end of the stopper 730 can extend to at least 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.

[0094] 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 respectively 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.

[0095] FIG. 5 is another perspective view of the electronic device 1000 shown in FIG. 4 in an unfolded state. Referring to FIGS. 4 and 5 together, in an embodiment of the present application, the cover 710 can further include an end cover 712 connected to one end of the top wall 711 away from the stopper 730 in the first direction x, and the end cover 712 is fixedly connected to the end portion 311, so that the cover 710 is fixed to the end portion 311 as a whole through the end cover 712. In an implementation, each of the two end portions 311 of the base 310 includes a protrusion 3111 arranged toward the side where the flexible display 400 is located, and each protrusion 3111 includes an end surface 3111a facing away from the other protrusion.

[0096] 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 protrusion 3111 of the corresponding end portion. Exemplarily, the end cover 712 and the end surface 3111a of the protrusion 3111 can be fixedly connected by bonding or welding. This design of fixing the end cover 712 to one side of the protrusion 3111 does not have a high requirement on the thickness (the dimension of the protrusion 3111 in 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 cover 712, thereby helping to reduce the axial length of the base 310, and further reducing the overall length of the electronic device 1000.

[0097] In some other embodiments, the protrusion 3111 is provided with a mounting groove, and the end cover 712 can be inserted into the mounting groove, so that the fixed connection between the end cover 712 and the protrusion 3111 can also be achieved.

[0098] Continuing to refer to FIGS. 4 and 5, the cover 710 can further include a first side wall 713 and a second side wall 714 connected to the two sides of the top wall 711 in the second direction y, respectively, and the first side wall 713 and the second side wall 714 are fixedly connected to the end portion 311, so that the cover 710 can also be fixed to 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 to improve the connection reliability between the cover 710 and the end portion 311.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] In the embodiment of the present application, the protruding surface of the protruding portion 3111 is provided with a groove 31111, and the guide column 720 can be located between the top wall 711 and the groove bottom of the groove 31111, that is, the guide column 720 and the protruding 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.

[0104] In some embodiments, the sliding portion 731 can have an extension block 7312 on the side facing the end cover 712, and at least part of the through hole 7311 is arranged on the extension block 7312. The width of the extension block 7312 along the second direction y is less than the width of the groove 31111 along the second direction y. When the shielding assembly 700 is assembled, the extension block 7312 can extend into the groove 31111 to facilitate sliding fit with the guide column 720 in the groove 31111.

[0105] Please continue to refer to FIG. 4 and FIG. 5, in the embodiment of the present application, the guide column 720 can be fixed to the top wall 711, so that the guide column 720 can be reliably positioned between the top wall 711 and the end portion 311. In one implementation, the guide column 720 and the top wall 711 can be an integral structure, which can not only improve the overall structural strength of the cover body 710, 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.

[0106] In addition, the end of the guide column 720 away from the top wall 711 and the end portion 311 can be in contact with each other or can be spaced apart, which is not limited in the present application. It is worth mentioning that in the case where the end of the guide column 720 away from the top wall 711 and the end portion 311 are spaced apart, the gap between the end of the guide column 720 away from the top wall 711 and the end portion 311 is less than the thickness of the stop block 730. Specifically, the gap between the end of the guide column 720 away from the top wall 711 and the end portion 311 is less than the thickness of the sliding portion 731, so as to reduce the risk of the sliding portion 731 being separated from the guide column 720 by the gap between the guide column 720 and the end portion, and improve the movement reliability of the stop block 730.

[0107] FIG. 6 is a schematic diagram of a partial cross-sectional structure of the electronic device 1000 shown in FIG. 4 in an unfolded state, and FIG. 7 is a schematic diagram of a partial cross-sectional structure of the electronic device 1000 shown in FIG. 4 in a folded state. Referring to FIGS. 6 and 7 together, 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 folded state, as the flexible display 400 is bent, the stopper 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 degree of freedom of movement 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 blocking structure and the bending area 430 of the flexible display 400 remains unchanged, in the present embodiment, the connection position of the sliding part 731 and the first part 732 and the connection position of the sliding part 731 and the second part 733 can both achieve smooth transition, and the connection position of the sliding part 731 and the first part 732 and the connection position of the sliding part 731 and the second part 733 can both achieve a relatively large bending radius, so as to release the bending stress of the stopper 730, reduce the risk of plastic deformation of the stopper 730 due to dead folding, and improve the structural reliability of the stopper 730.

[0108] After the electronic device 1000 is switched to the folded 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 folded state to the unfolded state, as the flexible display 400 is flattened, the first part 732 and the second part 733 of the stopper 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 stopper 730 returns to the natural state of no deformation after the electronic device 1000 is switched to the unfolded state.

[0109] FIG. 8 is a partial exploded view of another electronic device 1000 provided by an embodiment of the present application in an unfolded state. Referring to FIG. 8, in the present embodiment, the structural composition of the blocking assembly 700 is basically the same as that in the foregoing embodiments, except that the fixing manner of the guide column 720 is changed in the present embodiment. Specifically, in the present embodiment, the guide column 720 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 positional accuracy of the guide column 720, avoiding the design tolerance and assembly tolerance caused by separate processing and assembly of the guide column 720.

[0110] In the embodiment, the end of the guide column 720 away from the end portion 311 can be in contact with the top wall 711 or spaced apart from the top wall 711, which is not limited in the present application. In the case where the end of the guide column 720 away from the end portion 311 is spaced apart from the top wall 711, the gap between the end of the guide column 720 away from the end portion 311 and the top wall 711 is less than the thickness of the stop block 730, specifically, the gap between the end of the guide column 720 away from the end portion 311 and the top wall 711 is less than the thickness of the sliding portion 731, so as to reduce the risk that the sliding portion 731 is disengaged from the guide column 720 by the gap between the guide column 720 and the top wall 711, and improve the movement reliability of the stop block 730.

[0111] FIG. 9 is a schematic diagram of a partial cross-sectional structure of the electronic device 1000 shown in FIG. 8 in an unfolded state, and FIG. 10 is a schematic diagram of a partial cross-sectional structure of the electronic device 1000 shown in FIG. 8 in a folded state. Referring to FIGS. 9 and 10 together, in the unfolded state, the sliding portion 731 is located at the end of the guide column 720 close to the top wall 711, and the sliding portion 731 can be in contact with the top wall 711, for example. In the process of switching the electronic device 1000 from the unfolded state to the folded state, as the flexible display screen 400 is bent, the stop block 730 is also bent synchronously. Based on the sliding fit relationship between the sliding portion 731 and the guide column 720, the sliding portion 731 has a degree of freedom of movement in the thickness direction of the electronic device 1000, so the sliding portion 731 can slide along the guide column 720 towards the end portion 311. Compared with the design in the prior art in which the distance between the blocking structure and the bending area of the flexible display screen remains unchanged, in the embodiment, the connection position of the sliding portion 731 and the first portion 732 and the connection position of the sliding portion 731 and the second portion 733 can both achieve smooth transition, and the connection position of the sliding portion 731 and the first portion 732 and the connection position of the sliding portion 731 and the second portion 733 can both achieve a relatively large bending radius, so as to release the bending stress of the stop block 730, reduce the risk of plastic deformation of the stop block 730, and improve the structural reliability of the stop block 730.

[0112] After the electronic device 1000 is switched to the folded state, the sliding portion 731 is located at the end of the guide column 720 close to the end portion 311, and the sliding portion 731 can be in contact with the end portion 311, for example. In the process of switching the electronic device 1000 from the folded state to the unfolded state, as the flexible display screen 400 is unfolded, the first portion 732 and the second portion 733 of the stop block 730 are also unfolded relative to the sliding portion 731, and the sliding portion 731 slides along the guide column 720 towards 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.

[0113] FIG. 11 is a partial exploded view of another electronic device 1000 in an unfolded state according to an embodiment of the present disclosure. As shown in FIG. 11, in this embodiment, the structure of the blocking assembly 700 is basically the same as that of the foregoing embodiments, except that in this embodiment, the blocking block 730 can be arranged beyond the side edge of the flexible display 400 along the first direction x. In this case, the blocking block 730 can further include a first limiting wall 734 and a second limiting wall 735. The first limiting wall 734 is connected to one side of the first portion 732 beyond the side edge of the flexible display 400, and is arranged at an angle to the first portion 732. For example, the first limiting wall 734 can be substantially perpendicular to the first portion 732, and extends along the thickness direction of the electronic device 1000. Similarly, the second limiting wall 735 is connected to one side of the second portion 733 beyond the side edge of the flexible display 400, and is arranged at an angle to the second portion 733. For example, the second limiting wall 735 can be substantially perpendicular to the second portion 733, and extends along the thickness direction of the electronic device 1000.

[0114] In this 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 arranged between the side edge of the first fixed area 410 and the second blocking wall 520, and the second limiting wall 735 can be arranged 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 400 and the first limiting wall 734 and the second limiting wall 735, the flexible display 400 can limit the first limiting wall 734 and the second limiting wall 735, reduce the risk of the first portion 732 and the second portion 733 sliding to the display area of the flexible display 400, improve the installation position accuracy of the blocking block 730, and avoid affecting the display effect of the flexible display 400.

[0115] In addition, in this 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 present disclosure does not limit the fixing manner, which can be set as described in the foregoing embodiments.

[0116] Based on the same inventive concept, the embodiment of the present application provides another electronic device 1000. Referring to FIG. 12, FIG. 12 is a structural schematic diagram of the electronic device in an unfolded state. The electronic device 1000 can also include two shielding assemblies 700, which are respectively arranged at the two end portions 311 of the base, to shield 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 shielding assembly 700 and its application in the electronic device 1000 will be described in detail below.

[0117] FIG. 13 is a structural schematic diagram of another electronic device 1000 provided by the embodiment of the present application in an unfolded state, and FIG. 14 is an exploded view of the shielding assembly in the electronic device shown in FIG. 13. FIG. 13 shows the positional relationship between one of the shielding assemblies 700 and the corresponding end portion 311. Referring to FIGS. 13 and 14, in the embodiment of the present application, the two end portions 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 portion 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 portion, the top wall 711 is connected with the end cover 712, and the top wall 711 is arranged on the protruding face 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 cover body 710 can shield the edge of the flexible display screen 400 exposed to the outside, reduce the risk that the flexible display screen 400 is separated from the supporting surface 300a of the rotating shaft mechanism 300 due to the edge being subjected to an external force, and improve the reliability of the flexible display screen 400.

[0118] In addition, by covering the end cover 712 on the end surface 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 to 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 surface 3111a of the protruding portion 3111 can be adhesively or fixedly welded.

[0119] In an implementation, 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 along the second direction y is less than the width of the top wall 711 along the second direction y. The edge of the extension wall 7111 extends 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 edge of the bending area 430 of the flexible display screen 400 in the projection of the reference plane. This not only enables the cover body 710 to shield the edge of the flexible display screen 400 exposed outside, but also avoids interference between the extension wall 7111 and the flexible display screen 400 in the bending state when the electronic device is in the closed state, thereby helping to further improve the reliability of the flexible display screen 400.

[0120] With reference back to FIGS. 13 and 14, the cover body 710 can further include a first side wall 713 and a second side wall 714, which are respectively connected to the two sides of the top wall 711 along the second direction, and the first side wall 713 and the second side wall 714 are respectively fixedly connected to the end portion 311. The connection positions of the first side wall 713 and the second side wall 714 to the top wall 711 can be transitioned through a rounded corner to reduce the risk of the cover body being impacted. The size of the rounded corner can be designed according to the dimensions of the top wall 711, the first side wall 713 and the second side wall 714, which are 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 between 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 between 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 respectively connected to the two side surfaces of the protruding portion 3111 along the second direction y. This not only further increases the contact area between the cover body 710 and the end portion 311, and improves the connection strength between the cover body 710 and the end portion 311, but also positions the cover body 710 in the second direction by using the protruding portion 3111, and improves the assembly precision of the cover body 710 in the electronic device 1000.

[0121] Please continue to refer to FIG. 13 and FIG. 14, in the embodiment of the present application, the end 311 has a first limiting step 3112 and a second limiting step 3113 on two sides thereof along the second direction y, and the first limiting step 3112 and the second limiting step 3113 have step surfaces facing away from the side where the flexible display screen is located. The first side wall 713 has a first hook 7131 at an end thereof away from the top wall 711, and the second side wall 714 has a second hook 7141 at an end thereof away from the top wall 711, 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 means of the cooperation between the first hook 7131 and the first limiting step 3112 and the cooperation 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.

[0122] FIG. 15 is a structural schematic view of the cover body 710 provided in the embodiment of the present application. Referring to FIG. 14 and FIG. 15 together, in the embodiment of the present application, the protruding surface of the protruding 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 on the end, the positioning column 31112 can be inserted into the positioning groove 7112. By means of the insertion relationship therebetween, on the one hand, the cover body 710 can be positioned, and the installation position accuracy of the cover body 710 can be improved, and on the other hand, the positioning column 31112 and the positioning groove 7112 can be designed to have an interference fit by reasonable size design, so that the connection reliability of the cover body 710 and the protruding part 3111 can be improved.

[0123] It should be understood that the above-mentioned cooperation between the positioning column 31112 provided on the top wall 711 and the protruding part 3111 is not the only implementation form of the shielding assembly 700, and 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 along the thickness direction of the electronic device. Along the first direction, the stopper is located on the side of the cover body close to the flexible display screen, and the stopper covers the edge of the flexible display screen. In addition, the stopper includes a sliding part, the sliding part is opposite to the base 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 gap-fitted, so that the stopper can slide along the guide column in the thickness direction of the electronic device.

[0124] In specific implementations, the stopper can be made of a flexible material, and during the switching of the electronic device from the unfolded state to the closed state, the stopper can bend along with the flexible display screen, and during the switching of the electronic device from the closed state to the unfolded state, the stopper can gradually flatten along with the flexible display screen. Therefore, the stopper can shield the edge of the flexible display screen exposed outside in the unfolded state, the closed state, and the intermediate state, and in combination with the shielding effect of the cover, the reliability of the flexible display screen can be further improved.

[0125] In some embodiments, the stopper further includes a first portion and a second portion, and the first portion and the second portion are respectively connected to two sides of the sliding portion along the second direction. An end of the first portion away from the sliding portion is arranged between the first stop edge and the flexible display screen, and an end of the second portion away from the sliding portion 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.

[0126] In some embodiments, along the first direction, the side of the stopper close to the cover can be arranged beyond the edge of the flexible display screen. In this case, the stopper can further include a first limiting wall and a second limiting wall. 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, and 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. 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 using 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, reducing the risk of the first portion and the second portion sliding to the display area of the flexible display screen, improving the installation position accuracy of the stopper, and avoiding the influence of the stopper on the display effect of the flexible display screen.

[0127] In some embodiments, the guide post can be located between the top wall and the groove bottom, that is, the guide post and the protrusion are stacked along the thickness of the electronic device, and by this design, the guide post does not occupy additional space of the base in the first direction, thereby helping to further reduce the axial length of the base.

[0128] In some embodiments, the sliding part can have an extension block on the side facing the cover, and at least part of the through hole is arranged on the extension block. In 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 post in the groove.

[0129] In some embodiments, the guide post is fixed to the top wall, so that the guide post can be reliably positioned between the top wall and the end. For example, the guide post and the top wall can be an integral structure. In addition, the end of the guide post away from the top wall can be in contact with the end, or can be spaced apart. In the case where the end of the guide post away from the top wall is spaced apart from the end, the gap between the end of the guide post away from the top wall and the end is less than the thickness of the stopper, and specifically, the gap between the end of the guide post away from the top wall and the end is less than the thickness of the sliding part, so as to reduce the risk of the sliding part being separated from the guide post by the gap between the guide post and the end, and improve the movement reliability of the stopper.

[0130] 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 away from the end can be in contact with the top wall, or can be spaced apart. In the case where the end of the guide post away from the end is spaced apart from the top wall, the gap between the end of the guide post away from the end and the top wall is less than the thickness of the stopper, and specifically, the gap between the end of the guide post away from the end and the top wall is less than the thickness of the sliding part, so as to reduce the risk of the sliding part being separated from the guide post by the gap between the guide post and the top wall, and improve the movement reliability of the stopper.

[0131] Based on the same inventive concept, the embodiments of the present application provide another electronic device. Referring to FIG. 16, FIG. 16 is a structural schematic diagram of the electronic device 1000 in an unfolded state. The electronic device 1000 can also include two shielding assemblies 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 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 shielding assembly 700 and its application in the electronic device 1000 will be described in detail below.

[0132] FIG. 17 is a partial exploded view of the electronic device 1000 shown in FIG. 16 from one perspective in the unfolded state. Referring to FIG. 17, in embodiments of the present application, the shielding assembly 700 includes a cover 710 and a blocking piece 730, where the cover 710 is fixed to the end portion 311, the cover 710 includes a top wall 711 that covers a side of the end portion 311 facing the side on which the flexible display 400 is located, and the blocking piece 730 is fixedly connected to the top wall 711 and covers the edge of the flexible display 400. The blocking piece 730 can be made of a flexible material, for example, the blocking piece 730 can be a polyimide (PI) sheet or a steel sheet. During the switching of the electronic device 1000 from the unfolded state to the closed state, the blocking piece 730 can bend along with the flexible display 400, and during the switching of the electronic device 1000 from the closed state to the unfolded state, the blocking piece 730 can gradually flatten along with the flexible display 400. Therefore, in the unfolded state, the closed state, and the intermediate state of the electronic device 1000, the blocking piece 730 can shield the edge of the flexible display 400 exposed to the outside, thereby reducing the risk of the edge of the flexible display 400 coming into contact with the support surface of the shaft mechanism 300 due to external force, and improving the reliability of the flexible display 400.

[0133] In some embodiments, the shielding assembly 700 can further include a limiting piece 740, which is arranged in sequence with the top wall 711 and the blocking piece 730 along the thickness direction of the electronic device 1000, and the limiting piece 740 can fix the blocking piece 730 to the top wall 711. In specific implementations, the blocking piece 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 blocking piece 730. When the cover 710, the blocking piece 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, thereby fixing the blocking piece 730 to the top wall 711. For example, the limiting piece 740 can be made of metal or soft rubber, and the limiting piece 740 can be fixedly connected to the top wall 711 by welding or adhesion.

[0134] FIG. 18 is a structural schematic view of the shielding assembly 700 shown in FIG. 17 in the assembled state. Referring to FIGS. 17 and 18, in embodiments of the present application, the blocking piece 730 can include a fixed portion 737, which is located opposite the base 310 along the thickness direction of the electronic device 1000. When the blocking piece 730 is fixedly connected to the top wall 711, the fixed portion 737 can be connected to the top wall 711. It is easy to understand that, when the shielding assembly 700 includes the limiting piece 740, the positioning hole 736 of the blocking piece 730 can be arranged in the fixed portion 737, so that the fixing column 741 of the limiting piece 740 can pass through the positioning hole 736 and fix the fixed portion 737 to the top wall 711.

[0135] In addition, the stopper 730 can further include a first portion 732 and a second portion 733, and the arrangement direction of the first housing 100 and the second housing 200 is defined as the second direction y. Along the second direction y, the first portion 732 and the second portion 733 are respectively connected to the two sides of the fixed portion 737, and along the thickness direction of the electronic device 1000, the first portion 732 is opposite to the first housing 100 in position, and the second portion 733 is opposite to the second housing 200 in position. The end of the first portion 732 away from the fixed portion 737 is arranged between the first stop edge 500 and the flexible display screen 400, and the end of the second portion 733 away from the fixed portion 737 is arranged between the second stop edge 600 and the flexible display screen 400, that is, the two ends of the stopper 730 are respectively fixed and hidden by the first stop edge 500 and the second stop edge 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 stop edge 500 and the second stop edge 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, thereby improving the use reliability of the electronic device 1000.

[0136] FIG. 19 is a partial exploded view of the electronic device shown in FIG. 17 from another perspective. Referring to FIGS. 17 and 19 together, in the present embodiment, the cover body 710 can further include an end cover 712, which is connected to the end of the top wall 711 away from the stopper 730 along the first direction x, and the end cover 712 is fixedly connected to the end portion 311, so that the cover body 710 as a whole is fixed to the end portion 311 through the end cover 712. In one implementation, each end portion 311 of the base 310 includes a protruding portion 3111 arranged toward the side where the flexible display screen 400 is located, and each protruding portion 3111 includes an end face 3111a facing away from the other protruding portion.

[0137] In some embodiments, for each shielding assembly 700, the end cover 712 of the cover body 710 can be arranged on the end face 3111a of the protruding portion 3111 of the corresponding end portion. Exemplarily, the end cover 712 and the end face 3111a of the protruding portion 3111 can be fixedly connected by bonding or welding. This design of fixing the end cover 712 to one side of the protruding portion 3111 does not have a high requirement on the thickness (the dimension of the protruding portion 3111 in the first direction) of the protruding portion 3111, so the protruding portion 3111 can be implemented with a relatively small thickness to facilitate the fixed connection with the end cover 712, thereby helping to reduce the axial length of the base 310, and further reducing the overall length of the electronic device 1000.

[0138] 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 fixed connection between the end cover 712 and the protruding portion 3111 can also be achieved.

[0139] In some embodiments, the cover 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 y respectively, and the first side wall 713 and the second side wall 714 are fixedly connected to the end portion 311 respectively, so that the cover 710 can be fixed to 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.

[0140] In addition, the first side wall 713 and the second side wall 714 can be connected to the side of the protruding portion 3111 along the second direction y respectively, for example, by adhesive connection. In this way, the contact area of the cover 710 and the end portion 311 can be further increased, the connection strength of the cover 710 and the end portion 311 can be improved, and the cover 710 can be positioned in the second direction by using the protruding portion 3111, so as to improve the assembly precision of the cover 710 in the electronic device 1000.

[0141] 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 along the second direction y is less than the width of the top wall 711 along the second direction y. The projection of the extension wall 7111 in the first direction x covers part of the projection of the fixing portion 737 in the first direction x, and the fixing portion 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 a closed state, the extension wall 7111 can be prevented from interfering with the flexible display screen in the bent state, so as to further improve the reliability of the flexible display screen.

[0142] In the embodiments of the present application, other structural designs of the cover and the stopper can refer to the descriptions of the foregoing embodiments, which will not be repeated here.

[0143] The above merely illustrates the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which shall be covered in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
