Description

Technical Field

[0001] This application relates to the field of foldable electronic device technology, and particularly to a foldable electronic device. Background Technology

[0002] Currently, foldable electronic devices include a frame (small A-shell), a flexible display module, and multiple mid-frames. Each mid-frame is fixedly connected to the flexible display module. Along the direction perpendicular to the thickness of the flexible display module, there is a gap between the sidewall of the flexible display module and the inner sidewall of the frame of each mid-frame, and this gap is covered by the frame.

[0003] In related technologies, the bezel includes a horizontal portion and a vertical portion. The horizontal portion is located on the display side of the flexible display module, along a direction perpendicular to the thickness direction of the flexible display module. The vertical portion is located on one side of the flexible display module and is fixedly connected to the mid-frame. To prevent the display panel of the flexible display module from being damaged due to collision between the vertical portion and the sidewall of the flexible display module, a safety gap is provided between the inner sidewall of the vertical portion and the sidewall of the flexible display module. However, the setting of the safety gap also results in a larger bezel width for the foldable electronic device, reducing the aesthetic refinement of the foldable electronic device. Utility Model Content

[0004] This application provides a foldable electronic device that can reduce the bezel width of the foldable electronic device and improve its appearance.

[0005] In a first aspect, embodiments of this application provide a foldable electronic device, which includes a flexible display module, at least two mid-frames, at least two edge members, and at least two elastically deformable first buffer media. The flexible display module includes a display panel, each mid-frame is fixedly connected to the flexible display module, and at least one edge member is fixedly connected to each mid-frame. Each edge member includes a first component connected to the mid-frame. Along a first direction, the projection of the flexible display module and the projection of the first component do not coincide. Along a direction perpendicular to the first direction, there is a gap between the inner sidewall of the first component and the sidewall of the flexible display module, wherein the first direction is the thickness direction of the foldable electronic device. The first buffer media corresponds one-to-one with the edge members, and at least a portion of the first buffer media is fixedly connected to the inner sidewall of the first component of the corresponding edge member. Along a direction perpendicular to the first direction, at least a portion of the first buffer media is disposed within the gap between the sidewall of the display panel and the inner sidewall of the first component.

[0006] In this embodiment, a first, elastically deformable buffer medium is arranged in the gap between the sidewall of the display panel and the inner sidewall of the first component. When an external force drives one of the display panel and the frame component to move towards the other, the display panel or the frame component compresses the first buffer medium, causing the first buffer medium to deform. The first buffer medium acts as a buffer, preventing direct, hard friction or collision between the sidewall of the display panel and the inner sidewall of the frame component, thus preventing damage to the display panel. Furthermore, because the deformation of the first buffer medium is elastic, it can return to its original shape when the external force disappears, providing long-term buffer protection for the display panel.

[0007] Furthermore, since the first buffer medium can provide buffer protection for the sidewalls of the display panel, the gap between the sidewalls of the display panel and the frame member does not need to be set as the safety gap in the related technology. The gap between the sidewalls of the display panel and the inner sidewalls of the frame member can be designed as a small gap, thereby reducing the size of the frame member in the direction perpendicular to the first direction, and thus reducing the frame width of the foldable electronic device, which can improve the appearance and refinement of the foldable electronic device.

[0008] In some possible implementations, the foldable electronic device further includes at least one hinge assembly, at least two protective blocks, and at least two elastically deformable second buffer media. Each hinge assembly has a mid-frame at both ends along a second direction, which is perpendicular to the first and third directions, with the third direction being the axial direction of the hinge assembly. Each hinge assembly has a protective block at both ends along the third direction, each protective block including an end plate portion fixedly connected to the hinge assembly. Along the first direction, the projection of the flexible display module does not coincide with the projection of the end plate portion. Along the third direction, a gap exists between the inner sidewall of the end plate portion and the sidewall of the flexible display module. Each second buffer media corresponds to one of the protective blocks, with at least a portion of the second buffer media fixedly connected to the inner sidewall of the corresponding protective block's end plate portion. Along the third direction, at least a portion of the second buffer media is disposed within the gap between the sidewall of the display panel and the inner sidewall of the end plate portion.

[0009] In this embodiment, a second elastically deformable buffer medium is arranged in the gap between the sidewall of the display panel and the inner sidewall of the end plate. When an external force drives one of the display panel and the protective block to move towards the other, the display panel or the protective block compresses the second buffer medium, causing it to deform. The second buffer medium acts as a buffer, preventing direct, hard friction or collision between the sidewall of the display panel and the inner sidewall of the protective block, thus preventing damage to the display panel. Furthermore, because the deformation of the second buffer medium is elastic, it can return to its original shape when the external force disappears, providing long-term buffer protection for the display panel.

[0010] Furthermore, since the second buffer medium can provide buffer protection for the sidewalls of the display panel, the gap between the sidewalls of the display panel and the protective block does not need to be a large gap design. The gap between the sidewalls of the display panel and the inner sidewalls of the protective block can be a small gap design, thereby reducing the size of the protective block in the third direction, which in turn can further reduce the bezel width of the foldable electronic device and further improve the appearance refinement of the foldable electronic device.

[0011] In some possible implementations, at least one first buffer medium has at least one first sealed cavity, and / or, at least one first buffer medium has at least one first groove.

[0012] In this way, when an external force is applied to either the flexible display module or the frame component, the first buffer medium component is compressed and undergoes elastic deformation. Both the first sealed cavity and the first groove can provide the first buffer medium component with a larger deformation space, which can prolong the time of application of the external force, thereby reducing the external force applied to the other of the flexible display module and the frame component, and improving the buffer protection effect of the first buffer medium component on the display panel.

[0013] In some possible implementations, at least one first buffer medium is a solid structure. This configuration allows the first buffer medium to provide cushioning and protection. Furthermore, it reduces the manufacturing difficulty of the first buffer medium, thus helping to lower the cost of foldable electronic devices.

[0014] In some possible implementations, at least one first buffer medium has a gap with the sidewall of the flexible display module along a direction perpendicular to the first direction.

[0015] In this way, when an external force is applied to either the flexible display module or the frame component, the display panel or the first buffer medium will first move within the gap between the first buffer medium and the sidewall of the flexible display module. Only then will it come into contact with the other component and compress the first buffer medium, causing it to undergo elastic deformation. Compared to a situation where there is no gap between the two components, the display panel and the first buffer medium have a larger movable space. This allows for a longer time for the external force to travel from one component to the other, further reducing the force applied to the other component and thus enhancing the buffering protection effect of the first buffer medium on the display panel.

[0016] In some possible implementations, each frame component further includes a second component connected to a first end of the first component, and a second end of the first component connected to the mid-frame. Along a first direction, a portion of the second component is located on the display side of the flexible display module, and the projection of the second component coincides with the projection portion of the flexible display module. At least one first buffer medium component is fixedly connected to the inner wall of the corresponding second component and another portion is fixedly connected to the inner wall of the corresponding first component. Along the first direction, a portion of at least one first buffer medium component is located inside the gap between the front surface of the flexible display module and the inner wall of the second component.

[0017] In this way, by partially arranging the first buffer medium between the front of the flexible display module and the inner sidewall of the second component, the first buffer medium can buffer and protect the sidewall of the display panel while also buffering and protecting the front of the flexible display module.

[0018] In some possible implementations, along the first direction, the bottom surface of at least one first buffer medium is lower than the bottom surface of the display panel, and the top surface of at least one first buffer medium is higher than or flush with the top surface of the flexible display module.

[0019] In this way, along the first direction, the first buffer medium extends from a position below the bottom surface of the display panel to a position above or flush with the top surface of the flexible display module. The first buffer medium can provide buffer protection for the sidewalls of the display panel and the sidewalls of the layer structure above the display panel, which can further improve the reliability of the flexible display module.

[0020] In some possible implementations, the front side of the flexible display module is in contact with the first buffer medium.

[0021] In this way, the first buffer medium can not only provide buffer protection for the front of the flexible display module, but also reduce the gap between the front of the flexible display module and the second component, which helps to reduce the thickness of foldable electronic devices and facilitates the realization of a thinner and lighter design for electronic devices.

[0022] In some possible implementations, at least one first buffer medium and its corresponding frame are integrally formed. This configuration allows the first buffer medium and frame to be pre-fabricated using a single-piece molding process, simplifying the assembly process of the foldable electronic device. Furthermore, it improves the reliability of the connection between the frame and the first buffer medium.

[0023] In some possible implementations, at least one first buffer medium is bonded to a corresponding frame component. This arrangement reduces the difficulty of connecting the first buffer medium to the frame component, thereby reducing the manufacturing cost of the foldable electronic device.

[0024] In some possible implementations, at least one first buffer medium is a single, integral structure. This arrangement reduces the number of assembly steps in foldable electronic devices, thus improving assembly efficiency.

[0025] In some possible implementations, at least one first buffer medium includes a plurality of first buffer medium bodies arranged circumferentially spaced along the flexible display module. This arrangement, with gaps between adjacent first buffer medium bodies, reduces the difficulty of designing the gap between the inner sidewall of the bezel and the display panel, and can accommodate bezels with complex structures.

[0026] In some possible implementations, at least one second buffer medium has at least one second sealed cavity. And / or, at least one second buffer medium has at least two first grooves.

[0027] In this way, when an external force is applied to either the flexible display module or the protective block, the second buffer medium is squeezed and undergoes elastic deformation. Both the second sealed cavity and the first groove can provide the second buffer medium with a larger deformation space, which can prolong the time of application of the external force, thereby reducing the external force applied to the other of the flexible display module and the protective block, and thus improving the buffering and protection effect of the second buffer medium on the display panel.

[0028] In some possible implementations, at least one second buffer medium is a solid structure. This configuration allows the second buffer medium to provide cushioning and protection. Furthermore, it reduces the manufacturing complexity of the second buffer medium, thus helping to lower the cost of foldable electronic devices.

[0029] In some possible implementations, along a third direction, at least one second buffer medium has a gap between it and the sidewall of the flexible display module.

[0030] In this way, when an external force is applied to either the flexible display module or the protective block, the display panel and the second buffer medium will first move within the gap between the second buffer medium and the sidewall of the flexible display module, and then come into contact with the other component, compressing it and causing elastic deformation. Compared to a situation where there is no gap between them, the display panel and the second buffer medium have a larger space to move, allowing for a longer time from when the external force acts on one component to when it fully acts on the other. This further reduces the force acting on the other component, thereby further enhancing the buffering and protective effect of the second buffer medium on the display panel.

[0031] In some possible implementations, each protective block further includes a protrusion portion, and the two ends of the end plate portion are fixedly connected to the protrusion portion and the pivot assembly respectively along the first direction. Along the first direction, the flexible display module is located between the pivot assembly and the protrusion portion. At least one part of the second buffer medium is fixedly connected to the inner wall of the corresponding protrusion portion, and another part is fixedly connected to the inner wall of the corresponding end plate portion. Along the first direction, at least one part of the second buffer medium is located inside the gap between the front of the flexible display module and the inner wall of the protrusion portion.

[0032] In this way, by partially arranging the second buffer medium between the front of the flexible display module and the inner wall of the protrusion, the second buffer medium can also provide buffer protection for the front of the flexible display module.

[0033] In some possible implementations, along the first direction, the bottom surface of at least one second buffer medium is lower than the bottom surface of the display panel, and the top surface of at least one second buffer medium is higher than the top surface of the flexible display module.

[0034] In this way, along the first direction, the second buffer medium extends from a position below the bottom surface of the display panel to a position above or flush with the top surface of the flexible display module. The second buffer medium can provide buffer protection for the sidewalls of the display panel and the sidewalls of the layer structure above the display panel, which can further improve the reliability of the flexible display module.

[0035] In some possible implementations, the front side of the flexible display module contacts the second buffer medium.

[0036] In this way, the second buffer medium can not only provide buffer protection for the front of the flexible display module, but also reduce the gap between the front of the flexible display module and the protrusion, which helps to reduce the thickness of the foldable electronic device and facilitates the realization of a thinner and lighter design for the foldable electronic device.

[0037] In some possible implementations, at least one second buffer medium and the corresponding protective block are integrally formed. This configuration allows the second buffer medium and the protective block to be pre-fabricated using a single molding process, simplifying the assembly process of foldable electronic devices. Furthermore, it improves the reliability of the connection between the protective block and the second buffer medium.

[0038] In some possible implementations, at least one second buffer medium is bonded to a corresponding protective block. This arrangement reduces the difficulty of connecting the second buffer medium to the protective block, thereby reducing the manufacturing cost of foldable electronic devices.

[0039] In some possible implementations, at least one second buffer medium is an integral structure. This arrangement can reduce the assembly steps of foldable electronic devices and help improve the assembly efficiency of foldable electronic devices.

[0040] In some possible implementations, at least one second buffer medium includes a plurality of second buffer medium bodies arranged circumferentially spaced along the flexible display module. This arrangement, with gaps between adjacent second buffer medium bodies, reduces the complexity of designing the gap between the inner wall of the protective block and the display panel, and can accommodate protective blocks with complex structures.

[0041] In some possible implementations, the flexible display module further includes a first stack along a first direction, the first stack being located on the display side of the display panel and connected to the display panel, the first stack including at least one adhesive layer and at least one protective layer.

[0042] In this way, the adhesive layer can connect the protective layers, and also connect the protective layer to the display panel, thus connecting the first layer to the display panel. At the same time, the first layer can protect the display panel, improving its reliability.

[0043] In some possible implementations, along the first direction, the protective layer closest to the display panel in the first stack is a glass layer.

[0044] Thus, when the protective layer is made of glass, the creep of the glass is almost negligible, or in other words, the creep of the glass is very small. This results in very little creep in the portion of the glass layer located in the bending area of ​​the flexible display module, which can reduce the creep in the bending area of ​​the flexible display module, reduce stress concentration in the bending area, improve creases in the bending area, and enhance the flatness of the bending area.

[0045] In some possible implementations, a portion of the first buffer medium is disposed within the gap between the sidewall of the glass layer and the inner sidewall of the first component along a direction perpendicular to the first direction. And / or, the foldable electronic device further includes a protective block and a second buffer medium, a portion of which is disposed within the gap between the sidewall of the glass layer and the inner sidewall of the end plate portion of the protective block along a third direction.

[0046] In this way, the first buffer medium can prevent the glass layer from directly colliding or rubbing against the first component, thereby preventing the glass layer from breaking and achieving a buffering and protective function for the glass layer. The second buffer medium can prevent the glass layer from directly colliding or rubbing against the end plate, thereby preventing the glass layer from breaking and achieving a buffering and protective function for the glass layer.

[0047] In some possible implementations, the sidewalls of the glass layer are flush with the sidewalls of the display panel along a direction perpendicular to the first direction. This arrangement avoids the edges of the glass layer being located outside the edges of the display panel, helps to reduce the minimum gap between the sidewalls of the flexible display module and the inner sidewalls of the frame members, and helps to reduce the bezel width of foldable electronic devices.

[0048] In some possible implementations, the orthographic projection of the glass layer onto the display panel is located inside the display panel, and along a direction perpendicular to the first direction, the sidewalls of the glass layer are spaced apart from the sidewalls of the display panel. This configuration, with the edges of the glass layer recessed relative to the edges of the display panel, increases the gap between the glass layer and the frame components, improving the reliability of the glass layer.

[0049] In some possible implementations, foldable electronic devices also include a protective film layer that covers the sidewalls of the glass layer.

[0050] In this way, the protective film layer can seal the gap between the glass layer and the connected layers in the flexible display module, preventing gas from the inside of the foldable electronic device from entering the gap and improving the display effect of the flexible display module. In addition, the protective film layer can buffer and protect the sidewalls of the glass layer, further improving its reliability.

[0051] In some possible implementations, there are two protective layers. In the first stack, the protective layer furthest from the display panel is a non-glass layer, and the surface structure of the flexible display module is also a non-glass layer. Alternatively, there is one protective layer, and the surface structure of the flexible display module is a glass layer.

[0052] Thus, when there are two protective layers, the non-glass layer and the glass layer can provide double protection for the display panel. When there is only one protective layer, the glass layer protects the display panel while reducing the number of layers in the first stack, which can reduce the thickness of the flexible display module and help reduce the thickness of electronic devices.

[0053] In some possible implementations, the foldable electronic device also includes a protective film disposed on the top surface of the first stack.

[0054] In this way, the protective film can protect the front of the flexible display module, further improving the reliability of the flexible display module.

[0055] Secondly, embodiments of this application provide a foldable electronic device, including at least one hinge assembly, a flexible display module, at least two protective blocks, and at least two elastically deformable second buffer media. The flexible display module includes a display panel, and each protective block includes an end plate portion fixedly connected to the hinge assembly. Along a first direction, the projection of the flexible display module does not coincide with the projection of the end plate portion. Along a third direction, a gap exists between the inner sidewall of the end plate portion and the sidewall of the flexible display module. Protective blocks are provided at both ends of each hinge assembly. The second buffer media corresponds one-to-one with each protective block, and at least a portion of the second buffer media is fixedly connected to the inner sidewall of the end plate portion of the corresponding protective block. Along a third direction, at least a portion of the second buffer media is disposed within the gap between the sidewall of the display panel and the inner sidewall of the end plate portion.

[0056] In this embodiment, a second elastically deformable buffer medium is arranged in the gap between the sidewall of the display panel and the inner sidewall of the end plate. When an external force drives one of the display panel and the protective block to move towards the other, the display panel or the protective block compresses the second buffer medium, causing it to deform. The second buffer medium acts as a buffer, preventing direct, hard friction or collision between the sidewall of the display panel and the inner sidewall of the protective block, thus preventing damage to the display panel. Furthermore, because the deformation of the second buffer medium is elastic, it can return to its original shape when the external force disappears, providing long-term buffer protection for the display panel.

[0057] Furthermore, since the second buffer medium can provide buffer protection for the sidewalls of the display panel, the gap between the sidewalls of the display panel and the protective block does not need to be a large gap design. The gap between the sidewalls of the display panel and the inner sidewalls of the protective block can be a small gap design, thereby reducing the size of the protective block in the third direction, which in turn reduces the bezel width of the foldable electronic device and improves the appearance refinement of the foldable electronic device.

[0058] In some possible implementations, at least one second buffer medium has at least one second sealed cavity, and / or, at least one second buffer medium has at least two first grooves.

[0059] In this way, when an external force is applied to either the flexible display module or the protective block, the second buffer medium is compressed and undergoes elastic deformation. Both the second sealed cavity and the second groove can provide the second buffer medium with a larger deformation space, which can prolong the duration of the external force application. This reduces the external force acting on the other of the flexible display module and the protective block, thereby improving the buffering and protective effect of the second buffer medium on the display panel.

[0060] In some possible implementations, at least one second buffer medium is a solid structure. This configuration allows the second buffer medium to provide cushioning and protection. Furthermore, it reduces the manufacturing complexity of the second buffer medium, thus helping to lower the cost of foldable electronic devices.

[0061] In some possible implementations, along a third direction, at least one second buffer medium has a gap between it and the sidewall of the flexible display module.

[0062] In this way, when an external force is applied to either the flexible display module or the protective block, the display panel and the second buffer medium will first move within the gap between the second buffer medium and the sidewall of the flexible display module, and then come into contact with the other component, compressing it and causing elastic deformation. Compared to a situation where there is no gap between them, the display panel and the second buffer medium have a larger space to move, allowing for a longer time from when the external force acts on one component to when it fully acts on the other. This further reduces the force acting on the other component, thereby further enhancing the buffering and protective effect of the second buffer medium on the display panel.

[0063] In some possible implementations, each protective block further includes a protrusion portion, and the two ends of the end plate portion are fixedly connected to the protrusion portion and the pivot assembly respectively along the first direction. Along the first direction, the flexible display module is located between the pivot assembly and the protrusion portion. At least one part of the second buffer medium is fixedly connected to the inner wall of the corresponding protrusion portion, and another part is fixedly connected to the inner wall of the corresponding end plate portion. Along the first direction, at least one part of the second buffer medium is located inside the gap between the front of the flexible display module and the inner wall of the protrusion portion.

[0064] In this way, by partially arranging the second buffer medium between the front side of the flexible display module and the inner sidewall of the protrusion, the second buffer medium can also provide buffer protection for the front side of the flexible display module.

[0065] In some possible implementations, along the first direction, the bottom surface of at least one second buffer medium is lower than the bottom surface of the display panel, and the top surface of at least one second buffer medium is higher than the top surface of the flexible display module.

[0066] In this way, along the first direction, the second buffer medium extends from a position below the bottom surface of the display panel to a position above or flush with the top surface of the flexible display module. The second buffer medium can provide buffer protection for the sidewalls of the display panel and the sidewalls of the layer structure above the display panel, which can further improve the reliability of the flexible display module.

[0067] In some possible implementations, at least one second buffer medium and the corresponding protective block are integrally formed. This configuration allows the second buffer medium and the protective block to be pre-fabricated using a single molding process, simplifying the assembly process of foldable electronic devices. Furthermore, it improves the reliability of the connection between the protective block and the second buffer medium.

[0068] In some possible implementations, at least one second buffer medium is bonded to a corresponding protective block. This arrangement reduces the difficulty of connecting the second buffer medium to the protective block, thereby reducing the manufacturing cost of foldable electronic devices.

[0069] In some possible implementations, the flexible display module further includes a first stack along a first direction, the first stack being located on the display side of the display panel and connected to the display panel, the first stack including at least one adhesive layer and at least one protective layer.

[0070] In this way, the adhesive layer can connect the protective layers, and also connect the protective layer to the display panel, thus connecting the first layer to the display panel. At the same time, the first layer can protect the display panel, improving its reliability.

[0071] In some possible implementations, along the first direction, the protective layer closest to the display panel in the first stack is a glass layer.

[0072] Thus, when the protective layer is made of glass, the creep of the glass is almost negligible, or in other words, the creep of the glass is very small. This results in very little creep in the portion of the glass layer located in the bending area of ​​the flexible display module, which can reduce the creep in the bending area of ​​the flexible display module, reduce stress concentration in the bending area, improve creases in the bending area, and enhance the flatness of the bending area.

[0073] In some possible implementations, a portion of a second buffer medium is provided in the gap between the sidewall of the glass layer and the inner sidewall of the end plate portion of the protective block along a third direction.

[0074] In this way, the second buffer medium can prevent the glass layer from directly colliding or rubbing with the end plate, so as to avoid the glass layer from breaking and thus achieve the buffer protection function of the glass layer.

[0075] In some possible implementations, the sidewalls of the glass layer are flush with the sidewalls of the display panel along a direction perpendicular to the first direction. This arrangement avoids the edges of the glass layer being located outside the edges of the display panel, helps to reduce the minimum gap between the sidewalls of the flexible display module and the inner sidewalls of the protective block, and helps to reduce the bezel width of foldable electronic devices.

[0076] In some possible implementations, the orthographic projection of the glass layer onto the display panel is located inside the display panel, and along a direction perpendicular to the first direction, the sidewalls of the glass layer are spaced apart from the sidewalls of the display panel. This arrangement, with the edges of the glass layer recessed relative to the edges of the display panel, increases the gap between the glass layer and the protective block, improving the reliability of the glass layer.

[0077] In some possible implementations, foldable electronic devices also include a protective film layer that covers the sidewalls of the glass layer.

[0078] In this way, the protective film layer can seal the gap between the glass layer and the connected layers in the flexible display module, preventing gas from the inside of the foldable electronic device from entering the gap and improving the display effect of the flexible display module. In addition, the protective film layer can buffer and protect the sidewalls of the glass layer, further improving its reliability.

[0079] In some possible implementations, there are two protective layers. In the first stack, the protective layer furthest from the display panel is a non-glass layer, and the surface structure of the flexible display module is also a non-glass layer. Alternatively, there is one protective layer, and the surface structure of the flexible display module is a glass layer.

[0080] Thus, when there are two protective layers, the non-glass layer and the glass layer can provide double protection for the display panel. When there is only one protective layer, the glass layer protects the display panel while reducing the number of layers in the first stack, which can reduce the thickness of the flexible display module and help reduce the thickness of electronic devices.

[0081] In some possible implementations, the foldable electronic device also includes a protective film disposed on the top surface of the first stack.

[0082] In this way, the protective film can protect the front of the flexible display module, further improving the reliability of the flexible display module. Attached Figure Description

[0115] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0116] This application provides a foldable electronic device that has a folded state and an unfolded state. The foldable electronic device can change its shape by folding and unfolding to meet the needs of users in different scenarios. For example, it can be folded when carried to reduce its length or width. When in use, it can be unfolded to increase the area of ​​the display screen used for display or operation. The foldable electronic device can also be referred to as user equipment (UE) or a terminal, etc.

[0117] The foldable electronic devices provided in this application embodiment may include, but are not limited to, mobile phones, portable Android devices (PADs), laptops, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, in-vehicle devices, wearable devices, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes.

[0118] The following explanation uses a mobile phone as an example of a foldable electronic device. A mobile phone can be an inward-folding foldable phone, an outward-folding foldable phone, or a multi-folding foldable phone with either inward or outward folds.

[0119] Figure 1 This is a folding diagram of the foldable electronic device provided in the embodiments of this application. Figure 2 for Figure 1The diagram shows an unfolded schematic of the foldable electronic device. In the diagram, the first direction is defined as the thickness direction of the foldable electronic device when it is in the unfolded state, such as the Z direction; the second direction is defined as the length direction of the foldable electronic device when it is in the unfolded state, such as the X direction; and the third direction is defined as the axial direction of the hinge assembly 210 of the foldable electronic device, such as the Y direction.

[0120] In this embodiment of the application, the length direction of the foldable electronic device when it is in the unfolded state can be parallel to the direction perpendicular to the axis of the pivot assembly 210, and the width direction of the foldable electronic device when it is in the unfolded state can be parallel to the axis of the pivot assembly 210.

[0121] It should be noted that in the embodiments of this application, the two parallel directions can be absolutely parallel, or a certain degree of error can be allowed. For example, the axial direction of the hinge assembly 210 can be absolutely parallel to the width direction of the foldable electronic device, or the axial direction of the hinge assembly 210 can be set at an angle to the width direction of the foldable electronic device, for example, the angle between the two can be 1°, 2°, etc.

[0122] like Figure 1 As shown, the foldable electronic device includes a flexible display module 100 and a housing device 200, with the flexible display module 100 mounted on the housing device 200. The flexible display module 100 is used to display images. The housing device 200 can support the flexible display module 100, and the housing device 200 also allows the foldable electronic device to be in a folded state (e.g., ...). Figure 1 (as shown) and unfolded state (as shown) Figure 2 Switch between (as shown).

[0123] In this embodiment, the surface facing the user when the foldable electronic device is in its unfolded state is defined as the front side, and the surface facing away from the user when the foldable electronic device is in its unfolded state is defined as the back side. Similarly, the front side of each component in the foldable electronic device can also be understood as the surface facing the user when the foldable electronic device is in its unfolded state. For example, the front side of the flexible display module 100 is the surface facing the user, and the front side of the flexible display module 100 is also the display surface of the flexible display module 100. The back side of each component in the foldable electronic device can also be understood as the surface facing away from the user when the foldable electronic device is in its unfolded state.

[0124] In this embodiment, the length direction of the flexible display module 100 can be parallel to the length direction of the foldable electronic device, the width direction of the flexible display module 100 can be parallel to the width direction of the foldable electronic device, the width direction of the flexible display module 100 can also be parallel to the axial direction of the hinge assembly 210, and the thickness direction of the flexible display module 100 is parallel to the thickness direction of the foldable electronic device. Specifically, the length direction of the flexible display module 100 is the same as the length direction of the flexible display module 100 in the unfolded state, the width direction of the flexible display module 100 is the same as the width direction of the flexible display module 100 in the unfolded state, and the thickness direction of the flexible display module 100 is the same as the thickness direction of the flexible display module 100 in the unfolded state.

[0125] Figure 3 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application. Figure 4 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0126] like Figure 3 As shown, the foldable electronic device may also include a protective film 300 along a first direction (e.g., Figure 3 In the Z-direction, the protective film 300 and the flexible display module 100 are stacked together. The protective film 300 is disposed on the front side of the flexible display module 100 and is used to protect the front side of the flexible display module 100.

[0127] Of course, in addition to including the protective film 300, foldable electronic devices may also include, in some embodiments, such as Figure 4 As shown, the protective film 300 can also be removed from the foldable electronic device.

[0128] The foldable electronic device also includes a motherboard disposed within the housing 200 and electrically connected to the flexible display module 100. The motherboard may have devices such as a central processing unit (CPU), a graphics processing unit (GPU), and memory. For example, the motherboard may include a system-on-a-chip (SOC), which can integrate devices such as a CPU, a GPU, and memory.

[0129] Of course, in addition to components such as the motherboard, housing 200, flexible display module 100 and protective film 300, foldable electronic devices may also include other components that enable the foldable electronic device to function, such as batteries, camera modules, speakers, etc.

[0130] In some embodiments, such as Figure 3As shown, the protective film 300 can be connected to the flexible display module 100 via the first optical adhesive layer 400. Exemplarily, the first optical adhesive layer 400 can be made of optically clear adhesive (OCA), such as acrylic or silicone-based optically clear adhesives. Alternatively, the first optical adhesive layer 400 can also be made of optically clear resin (OCR), such as epoxy resin.

[0131] In some embodiments, the protective film 300 may be a PET (polyethylene terephthalate) film or a CPI (colorless polyimide) film, etc.

[0132] In some embodiments, see Figure 2 The housing device 200 may include at least one pivot assembly 210 and at least two middle frames 220. Along the second direction, each pivot assembly 210 has a middle frame 220 on each side. Two adjacent middle frames 220 are rotatably connected by a pivot assembly 210 so that the foldable electronic device can switch between a folded state and an unfolded state.

[0133] The number of pivot assemblies 210 is one or more, and the number of middle frames 220 is two or more.

[0134] For example, such as Figure 2 As shown, the housing device 200 may include a first middle frame 221, a second middle frame 222, and a pivot assembly 210. The first middle frame 221 is rotatably connected to the second middle frame 222 via the pivot assembly 210. Of course, the number of pivot assemblies 210 may be more than one. For example, in some embodiments, the housing device 200 may include a first middle frame 221, a second middle frame 222, a third middle frame, a first pivot assembly 210, and a second pivot assembly. The first middle frame 221 is rotatably connected to one end of the second middle frame 222 via the first pivot assembly 210, and the other end of the second middle frame 222 is rotatably connected to the third middle frame via the second pivot assembly.

[0135] like Figure 1 As shown, when the foldable electronic device is in the folded state, two adjacent mid-frames 220 rotate to overlap each other.

[0136] like Figure 2As shown, when the foldable electronic device is in the unfolded state, the two adjacent mid-frames 220 rotate until the included angle between them is approximately 180°. Those skilled in the art will understand that the included angle referred to in this application as approximately 180° may not be an absolute 180° due to design tolerances and other reasons, and slight deviations are allowed, such as 165°, 177°, or 185°.

[0137] For example, the middle frame 220 can be fixedly connected to the pivot assembly 210 by means of welding, bonding, threaded connection, etc.

[0138] like Figure 1 As shown, the housing device 200 also includes at least two back covers 230, which correspond one-to-one with the middle frame 220. The back covers 230 and the flexible display module 100 are located on opposite sides of the middle frame 220 in the first direction. The back covers 230 are fixedly connected to the middle frame 220. The back covers 230 and the middle frame 220 can together form a storage space, which can be used to accommodate components such as batteries, camera modules, and circuit boards.

[0139] In some embodiments, at least one back cover 230 may be replaced with a display screen, such that the foldable electronic device has an outer screen. Exemplarily, the housing device 200 includes two mid-frames 220, one mid-frame 220 having the back cover 230 disposed thereon and the other mid-frame 220 having the display screen disposed thereon.

[0140] The flexible display module 100 in this application embodiment may include, but is not limited to, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (Mini LED) display screen, a micro light-emitting diode (Micro LED) display screen, a micro organic light-emitting diode (Micro OLED) display screen, a quantum dot light-emitting diode (QLED) display screen, etc.

[0141] like Figure 3As shown, the flexible display module 100 includes a first stack 110 and a display panel 120. Along the thickness direction of the flexible display module 100, the display panel 120 has a display side for displaying images and a non-display side disposed opposite to the display side. The first stack 110 is located on the display side of the display panel 120 and is connected to the display panel 120.

[0142] Among them, when the foldable electronic device has a protective film 300, such as Figure 3 As shown, a protective film 300 is disposed on the top surface of the first stack 110 along the first direction. The protective film 300 can be connected to the top surface of the first stack 110 via a first optical adhesive layer 400.

[0143] In this way, the protective film 300 can protect the front of the flexible display module 100, further improving the reliability of the flexible display module 100.

[0144] Figure 5 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0145] In some embodiments, the first stack 110 may include at least one adhesive layer 111 and at least one protective layer 112. The adhesive layer 111 can connect the protective layers 112 and also connect the protective layers 112 to the display panel 120, thus connecting the first stack 110 to the display panel 120. Simultaneously, the first stack 110 can protect the display panel 120, improving its reliability.

[0146] The adhesive layer 111 has good adhesion and light transmission properties. For example, the adhesive layer 111 can be made of optically transparent adhesive or optically transparent resin.

[0147] Among them, such as Figure 4 As shown, when the first stack 110 includes multiple adhesive layers 111 and multiple protective layers 112, two adjacent protective layers 112 can be connected through adhesive layers 111, so that each protective layer 112 can form a whole. Along the first direction, the protective layer 112 closest to the display panel 120 can be connected to the display panel 120 through adhesive layers 111. In this way, the connection between the first stack 110 and the display panel 120 can be realized, so that the first stack 110 can protect the display panel 120.

[0148] Among them, such as Figure 5As shown, when the first stack 110 includes an adhesive layer 111 and a protective layer 112, the protective layer 112 can be connected to the display panel 120 through the adhesive layer 111. In this way, the connection between the first stack 110 and the display panel 120 can be realized, thereby enabling the first stack 110 to protect the display panel 120.

[0149] In some possible implementations, such as Figure 4 As shown, along the first direction, the protective layer 112 closest to the display panel 120 in the first stack 110 is a glass layer 1121. Thus, when the material of the protective layer 112 is glass, the creep of the glass is almost negligible, or in other words, very small. This results in very small creep in the portion of the glass layer 1121 located in the bending area of ​​the flexible display module 100, reducing creep in the bending area of ​​the flexible display module 100, reducing stress concentration in the bending area, improving creases in the bending area, and enhancing the flatness of the bending area.

[0150] Of course, in some embodiments, in addition to being a glass layer 1121, the protective layer 112 closest to the display panel 120 in the first stack 110 along the first direction may also be a non-glass layer 1122.

[0151] In some embodiments, the glass layer 1121 may be a UTG (ultra-thin glass) layer. The UTG layer has a lower thickness, which can reduce the thickness of the flexible display module 100, thereby reducing the thickness of the foldable electronic device.

[0152] In some embodiments, the glass layer 1121 can be a glass layer of uniform thickness. In this case, the thickness of each part of the glass layer 1121 is consistent or approximately consistent along a direction perpendicular to the first direction (such as the second direction).

[0153] In some embodiments, the glass layer 1121 can be a glass layer of unequal thickness. For example, along the second direction, the glass layer 1121 may include a first glass portion and a second glass portion. The first glass portion is located in the bending region of the flexible display module 100, and the second glass portion is located in the non-bending region of the flexible display module 100. The thickness of the first glass portion is less than the thickness of the second glass portion, which can reduce the difficulty of bending the first glass portion, thereby reducing the difficulty of bending the flexible display module 100.

[0154] In some possible implementations, such as Figure 4As shown, there are two protective layers 112. In the first stack 110, the protective layer 112 furthest from the display panel 120 is a non-glass layer 1122. The surface structure of the flexible display module 100 is also a non-glass layer 1122. In this case, the glass layer 1121 is located between the non-glass layer 1122 and the display panel 120. This provides double-layer protection for the display panel 120.

[0155] For example, the non-glass layer 1122 can be a PET layer, a CPI layer, etc.

[0156] Of course, in some embodiments, the protective layer 112 that is farthest from the display panel 120 in the first stack 110 may also be a glass layer 1121, in addition to being a non-glass layer 1122. In this case, both protective layers 112 may be glass layers 1121, or one of the two protective layers 112 may be a glass layer 1121 and the other may be a non-glass layer 1122.

[0157] In some possible implementations, such as Figure 5 As shown, the protective layer 112 is a single layer, and the protective layer 112 can be a glass layer 1121. That is to say, the surface structure of the flexible display module 100 can be a glass layer 1121. In this way, the glass layer 1121 can protect the display panel 120, and at the same time, the number of layers in the first stack 110 can be reduced to reduce the thickness of the flexible display module 100, thereby reducing the thickness of the electronic device.

[0158] When the number of protective layers 112 is one, in addition to being a glass layer 1121, in some embodiments, the protective layer 112 can also be a non-glass layer 1122.

[0159] Of course, in addition to one or two protective layers, in some embodiments, the number of protective layers 112 can also be three or more.

[0160] It is understood that when there are three or more protective layers 112, the protective layer 112 closest to the display panel 120 in the first stack 110 can be a non-glass layer 1122, and the protective layer 112 farthest from the display panel 120 in the first stack 110 can be a glass layer 1121. Alternatively, in some embodiments, both the protective layer 112 closest to the display panel 120 and the protective layer 112 farthest from the display panel 120 in the first stack 110 can be a glass layer 1121.

[0161] Figure 6 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application. Figure 7This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0162] In some embodiments, such as Figure 6 As shown, along a direction perpendicular to the first direction, such as the second direction, the sidewall of the glass layer 1121 is flush with the sidewall of the display panel 120. This arrangement prevents the edge of the glass layer 1121 from being located outside the edge of the display panel 120, which helps to reduce the minimum gap between the sidewall of the flexible display module 100 and the inner sidewall of the frame member 600, and helps to reduce the bezel width of the foldable electronic device.

[0163] Of course, in addition to being flush with the sidewall of the display panel 120, the sidewall of the glass layer 1121 can also be, in some embodiments, such as... Figure 4 As shown, the orthographic projection of the glass layer 1121 onto the display panel 120 is located inside the display panel 120, and along a direction perpendicular to the first direction, such as the second direction, the sidewalls of the glass layer 1121 are spaced apart from the sidewalls of the display panel 120. This arrangement, with the edge of the glass layer 1121 recessed relative to the edge of the display panel 120, increases the gap between the glass layer 1121 and the frame member 600, improving the reliability of the glass layer 1121.

[0164] Of course, in addition to being flush with the sidewall of the display panel 120 or located inside the sidewall of the display panel 120, the sidewall of the glass layer 1121 can also be, in some embodiments, such as... Figure 7 As shown, the sidewall of the glass layer 1121 can also be located outside the sidewall of the display panel 120. That is, the orthographic projection of the display panel 120 onto the glass layer 1121 is located inside the glass layer 1121, and along a direction perpendicular to the first direction, such as the second direction, the sidewall of the glass layer 1121 is spaced apart from the sidewall of the display panel 120. Therefore, the sidewall of the glass layer 1121 can protrude outward from the sidewall of the display panel 120.

[0165] In some embodiments, such as Figure 4 or Figure 6 As shown, the foldable electronic device also includes a protective film layer 500, which covers the sidewalls of the glass layer 1121.

[0166] Typically, there may be tiny gaps between the sidewalls of the glass layer 1121 and the connected layer structures in the flexible display module 100. Gas from outside the flexible display module 100 may enter through these gaps and form bubbles, affecting the display performance. Therefore, sealing the gaps between the glass layer 1121 and the connected layer structures in the flexible display module 100 with the protective film layer 500 can prevent gas from entering the gaps, thus improving the display performance of the flexible display module 100. Furthermore, the protective film layer 500 can buffer and protect the sidewalls of the glass layer 1121, further improving its reliability.

[0167] In some embodiments, the protective film layer 500 may also be called a coating layer.

[0168] The protective film layer 500 can be an optical epoxy resin film layer, an acrylic film layer, a polyimide (PI) film layer, etc.

[0169] Of course, in addition to covering only the sidewalls of the glass layer 1121, the protective film layer 500 can also cover the bottom wall of the glass layer 1121 near the display panel 120, and / or the top wall of the glass layer 1121 away from the display panel 120. When the protective film layer 500 covers the top and / or bottom walls of the glass layer 1121, it can also provide explosion-proof and impact-resistant protection.

[0170] In some embodiments, such as Figure 4 As shown, along a direction perpendicular to the first direction, the sidewalls of the protective film layer 500 can be flush with the sidewalls of the display panel 120. In some embodiments, the orthographic projection of the protective film layer 500 onto the display panel 120 is located inside the display panel 120, and the sidewalls of the protective film layer 500 are spaced apart from the sidewalls of the display panel 120 along a direction perpendicular to the first direction. In some embodiments, along a direction perpendicular to the first direction, the sidewalls of the protective film layer 500 are located between the sidewalls of the display panel 120 and the outer sidewalls of the middle frame 220.

[0171] In some possible implementations, such as Figure 3 As shown, the flexible display module 100 may further include a second stack 130. Along the thickness direction of the flexible display module 100, the second stack 130 is located on the non-display side of the display panel 120 and is connected to the display panel 120.

[0172] Of course, in addition to including the second stack 130, the flexible display module 100 may also omit the second stack 130 in some embodiments.

[0173] In some embodiments, such as Figure 7 As shown, the second stack 130 may include a first support layer 131 and a second support layer 132. The first support layer 131 may be disposed between the display panel 120 and the second support layer 132 along a first direction. The first support layer 131 provides support and protection for the display panel 120, while the second support layer 132 provides support for the back of the display panel 120.

[0174] Of course, in addition to being constructed by the first support layer 131 and the second support layer 132, the second stack 130 can also be constructed by fewer or more support layers. For example, in some embodiments, the second stack 130 can also be constructed by stacking the first support layer 131, the second support layer 132 and the third support layer.

[0175] In some embodiments, the first support layer 131 may be a back support film (or back membrane). The material of the back support film may include, but is not limited to, PET or SUS (stainless steel).

[0176] In some embodiments, the back support membrane may also be referred to as Ufilm.

[0177] In some embodiments, the second support layer 132 may be a bamboo book (BKT) layer.

[0178] In some embodiments, the second support layer 132 can be bonded to the middle frame 220 using adhesive, dispensing, or other methods to connect the flexible display module 100 to the middle frame 220. Alternatively, the second support layer 132 may not be physically connected to the middle frame 220.

[0179] In some embodiments, such as Figure 7 As shown, the second stack 130 may further include a second optical adhesive layer 133 and a third optical adhesive layer 134. The first support layer 131 can be bonded to the display panel 120 via the second optical adhesive layer 133, and the second support layer 132 can be bonded to the first support layer 131 via the third optical adhesive layer 134. Exemplarily, both the second optical adhesive layer 133 and the third optical adhesive layer 134 can be made of optically transparent adhesive or optically transparent resin.

[0180] Figure 8 This is a schematic diagram of a foldable electronic device provided in related technologies.

[0181] In related technologies, such as Figure 8As shown, the foldable electronic device includes a flexible display module 10, a mid-frame 20, and a frame piece (small A-shell) 30. The frame piece 30 and the flexible display module 10 are fixedly connected to the mid-frame 20. To prevent the flexible display module 10 from colliding with the mid-frame 20 and causing damage to the flexible display module 10, a gap is formed between the sidewall of the flexible display module 10 and the inner sidewall of the frame of the mid-frame 20 along a direction perpendicular to the thickness direction of the flexible display module 10. This gap is covered by the frame piece 30.

[0182] Among them, such as Figure 8 As shown, the frame member 20 includes a horizontal portion 31 and a vertical portion 32, which are connected. The horizontal portion 31 is located on the display side of the flexible display module 10, and can block the gap between the side wall of the flexible display module 10 and the inner side wall of the frame member 20. Along a direction perpendicular to the thickness direction of the flexible display module 10, the vertical portion 32 is located on one side of the flexible display module 10 and is fixedly connected to the middle frame 20, thereby achieving a fixed connection between the frame member 30 and the middle frame 20.

[0183] To prevent damage to the display panel of the flexible display module 10 caused by collision between the vertical part 32 and the side wall of the flexible display module 10, a safety gap is provided between the inner side wall of the vertical part 32 and the side wall of the flexible display module 10. However, the setting of the safety gap also results in a larger bezel width for the foldable electronic device, reducing the aesthetic appeal of the foldable electronic device.

[0184] The bezel width of the foldable electronic device refers to the distance between the side wall of the horizontal part 31 and the outer side wall of the middle frame 20 along the direction perpendicular to the thickness direction of the flexible display module (as shown by L1 in the figure).

[0185] Figure 9 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0186] In view of this, see some possible implementations. Figure 9 The foldable electronic device also includes at least two frame members 600 and at least two elastically deformable first buffer media members 700. Wherein, as Figure 9 As shown, each frame component 600 includes a second component 610 and a first component 620. The second component 610 is connected to the first end of the first component 620, and the second end of the first component 620 is connected to the middle frame 220 along a first direction (e.g., Figure 9 In the Z-direction, a portion of the second component 610 is located on the display side of the flexible display module 100, and the projection of the second component 610 coincides with the projection portion of the flexible display module 100. Along the first direction, the projection of the flexible display module 100 does not coincide with the projection of the first component 620. Along a direction perpendicular to the first direction, such as the second direction (e.g., ... Figure 9 In the X direction, a gap exists between the inner sidewall of the first component 620 and the sidewall of the flexible display module 100. A first buffer medium 700 corresponds one-to-one with a frame component 600, and at least a portion of the first buffer medium 700 is fixedly connected to the inner sidewall of the corresponding frame component 600's first component 620. Along a direction perpendicular to the first direction, such as the second direction, at least a portion of the first buffer medium 700 is disposed within the gap between the sidewall of the display panel 120 and the inner sidewall of the first component 620.

[0187] Each middle frame 220 is fixedly connected to at least one border piece 600. For example, when there are two middle frames 220, each middle frame 220 is connected to one border piece 600. Alternatively, when there are three middle frames 220, one middle frame 220 is fixedly connected to two border pieces 600, and the other two border pieces 600 are each fixedly connected to one border piece 600.

[0188] Among them, the frame component 600 can also be called a small A-shell, decorative component, etc.

[0189] The bezel member 600 can be disposed around the edge of the flexible display module 100, and can protect the edge of the flexible display module 100. That is, the second part 610 and the first part 620 of the bezel member 600 can jointly protect the edge of the flexible display module 100. At the same time, along a direction perpendicular to the first direction, such as the second direction, the second part 610 can extend from the first part 620 to the display side of the flexible display module 100 to block the gap between the sidewall of the flexible display module 100 and the inner sidewall of the bezel of each middle frame 220.

[0190] The first component 620 can be fixedly connected to the middle frame 220 by means of adhesive dispensing, screw connection, etc., so as to achieve a fixed connection between the side frame 600 and the middle frame 220.

[0191] By arranging an elastically deformable first buffer medium 700 in the gap between the side wall of the display panel 120 and the inner side wall of the first component 620, when an external force drives one of the flexible display module 100 and the frame component 600 to move towards the other, the display panel 120 or the frame component 600 squeezes the first buffer medium 700, causing the first buffer medium 700 to deform. The first buffer medium 700 plays a buffering role, which can prevent the side wall of the display panel 120 from having direct and hard friction or collision with the inner side wall of the frame component 600, and can prevent damage to the display panel 120.

[0192] Specifically, since the first buffer medium 700 can deform, according to the momentum theorem, the first buffer medium 700 can prolong the displacement time of one of the display panel 120 and the first component 620 through its own compressive deformation, thereby prolonging the duration of the external force and reducing the magnitude of the external force acting on the other of the display panel 120 and the first component 620. This prevents direct, hard friction or collision between the sidewall of the display panel 120 and the inner sidewall of the frame component 600, thus avoiding damage to the display panel 120. In addition, since the deformation of the first buffer medium 700 is elastic, it can return to its original shape when the external force disappears, allowing the first buffer medium 700 to provide long-term buffer protection for the display panel 120.

[0193] For example, when an external force is applied to the flexible display module 100 and causes it to bend, misalignment occurs between the various layers of the flexible display module 100 in a direction perpendicular to the first direction, such as the second direction. The misaligned layers will move towards the first buffer medium 700 and compress it. As another example, when the frame member 600 deforms under external force, such as when a foldable electronic device is bumped or dropped, the impact force will cause the frame member 600 to deform, which will cause the first buffer medium 700 to move towards the display panel 120 and be compressed.

[0194] Furthermore, since the first buffer medium 700 can provide good buffer protection for the sidewall of the display panel 120, the gap between the sidewall of the display panel 120 and the frame member 600 does not need to be set as the safety gap in the related technology. The gap between the sidewall of the display panel 120 and the inner sidewall of the frame member 600 can be designed as a small gap, thereby reducing the size of the frame member 600 in the direction perpendicular to the first direction, and thus reducing the frame width of the foldable electronic device (as shown by L2 in the figure), which can improve the appearance and refinement of the foldable electronic device.

[0195] In some possible implementations, the first buffer medium 700 may be made of at least one of the following materials: foam, silicone, thermoplastic polyurethane (TPU), and thermoplastic elastomer (TPE).

[0196] In some embodiments, such as Figure 9As shown, at least one first buffer medium 700 can be a solid structure; for example, all first buffer mediums 700 are solid structures. This configuration allows the first buffer mediums 700 to provide cushioning and protection. Furthermore, it reduces the manufacturing difficulty of the first buffer mediums 700, which helps to lower the cost of foldable electronic devices.

[0197] Figure 10 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0198] In some embodiments, such as Figure 10 As shown, at least one first buffer medium 700 has at least one first sealed cavity 710. For example, each first buffer medium 700 has one or more first sealed cavities 710. When the first buffer medium 700 has a first sealed cavity 710, the first sealed cavity 710 can be a cavity that is not connected to the outside of the first buffer medium 700. When an external force is applied to either the flexible display module 100 or the frame member 600, the first buffer medium 700 is compressed and undergoes elastic deformation. The first sealed cavity 710 can provide the first buffer medium 700 with a larger deformation space, which can prolong the time of application of the external force, thereby reducing the external force applied to the other of the flexible display module 100 and the frame member 600, and improving the buffering protection effect of the first buffer medium 700 on the display panel 120.

[0199] The first buffer medium 700 may have multiple or one first sealed cavity 710. When there are multiple first sealed cavities 710, the multiple first sealed cavities 710 can be arranged at intervals.

[0200] The number of first buffer media 700 can be multiple or one. When there are multiple first buffer media 700, the number of first sealed cavities 710 of each first buffer media 700 is the same, or, a portion of the first sealed cavities 710 of the multiple first buffer media 700 are the same, while the number of other portions is different.

[0201] The embodiments of this application do not restrict the arrangement direction of the plurality of first sealed cavities 710. For example, the plurality of first sealed cavities 710 may be arranged along the first direction or in a direction having an angle with the first direction.

[0202] Figure 11 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0203] In some embodiments, such as Figure 11As shown, at least one first buffer medium 700 has at least one first through hole 720. For example, each first buffer medium 700 has one or more first through holes 720. When the first buffer medium 700 has a first through hole 720, the first through hole 720 is a hole that penetrates the solid portion of the first buffer medium 700. When an external force is applied to either the flexible display module 100 or the frame member 600, the first buffer medium 700 is compressed and undergoes elastic deformation. The first through hole 720 allows the first buffer medium 700 to have a larger deformation space, which can prolong the time of application of the external force, thereby reducing the external force applied to the other of the flexible display module 100 and the frame member 600, and improving the buffering protection effect of the first buffer medium 700 on the display panel 120.

[0204] The first buffer medium 700 may have multiple or one first through hole 720. When there are multiple first through holes 720, the multiple first through holes 720 can be arranged at intervals.

[0205] The number of first buffer media 700 can be multiple or one. When there are multiple first buffer media 700, the number of first through holes 720 of each first buffer media 700 is the same, or, a portion of the multiple first buffer media 700 has the same number of first through holes 720, while the number of other portions is different.

[0206] The embodiments of this application do not limit the arrangement direction of the plurality of first through holes 720. For example, the plurality of first through holes 720 can be arranged along the first direction or in a direction having an angle with the first direction.

[0207] The specific location of the first through hole 720 is not limited in the embodiments of this application. For example, the first through hole 720 may penetrate the solid part of the first buffer medium 700 in a third direction.

[0208] The cross-sectional shape of the first through hole 720 is not limited in this application embodiment. For example, the cross-sectional shape of the first through hole 720 can be a regular shape such as an ellipse, circle, quadrilateral or pentagon, or it can be an irregular shape.

[0209] Figure 12 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application. Figure 13 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0210] In some embodiments, such as Figure 12 or Figure 13As shown, at least one first buffer medium 700 has at least one first groove 730. For example, each first buffer medium 700 has one or more first grooves 730. When the first buffer medium 700 has a first groove 730, the first groove 730 is a groove disposed on the surface of the first buffer medium 700. When an external force is applied to either the flexible display module 100 or the frame member 600, the first buffer medium 700 is compressed and undergoes elastic deformation. The first groove 730 can provide the first buffer medium 700 with a larger deformation space, which can prolong the time of application of the external force, thereby reducing the external force applied to the other of the flexible display module 100 and the frame member 600, and improving the buffering protection effect of the first buffer medium 700 on the display panel 120.

[0211] The number of first buffer media 700 can be multiple or one. When there are multiple first buffer media 700, the number of first grooves 730 in each first buffer media 700 is the same, or, a portion of the multiple first buffer media 700 have the same number of first grooves 730, while the number of other portions are different.

[0212] Among them, such as Figure 12 As shown, the opening of the first groove 730 can face the flexible display module 100, or, as... Figure 13 As shown, the opening of the first groove 730 can face the frame member 600.

[0213] The first buffer medium 700 may have multiple or one first groove 730. When there are multiple first grooves 730, each first groove 730 faces the same direction, or, some of the first grooves 730 have the same groove opening direction, while the groove openings of other parts do not face the same direction.

[0214] The embodiments of this application do not limit the arrangement direction of the plurality of first grooves 730. For example, the plurality of first grooves 730 may be arranged along the first direction or in a direction having an angle with the first direction.

[0215] In some embodiments, at least one first buffer medium 700 has one of a first sealed cavity 710, a first through hole 720, and a first groove 730.

[0216] In some embodiments, at least one first buffer medium 700 may simultaneously have at least two of the first sealed cavity 710, the first through hole 720, and the first groove 730. For example, each first buffer medium 700 may simultaneously have the first sealed cavity 710 and the first groove 730. Thus, the first buffer medium 700 may have different types of buffer structures.

[0217] Figure 14This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0218] In some embodiments, such as Figure 14 As shown, the sidewall of the flexible display module 100 can contact the first buffer medium 700, thus indicating that the sidewall of the display panel 120 can also contact the first buffer medium 700. In this way, while the first buffer medium 700 provides cushioning protection for the display panel 120, the safety gap between the flexible display module 100 and the mid-frame 220 is smaller, further enhancing the refined appearance of the foldable electronic device along a direction perpendicular to the first direction.

[0219] Of course, in addition to contacting the first buffer medium 700, the sidewalls of the flexible display module 100 can also be used in some embodiments, such as... Figure 9 As shown, the sidewall of the flexible display module 100 may not be in contact with the first buffer medium 700. Along a direction perpendicular to the first direction, there is a gap between the first buffer medium 700 and the sidewall of the flexible display module 100.

[0220] When an external force is applied to either the flexible display module 100 or the frame member 600, one of the display panel 120 and the first buffer medium 700 will first move within the gap between the first buffer medium 700 and the sidewall of the flexible display module 100, and then come into contact with the other of the display panel 120 and the first buffer medium 700, thus squeezing the first buffer medium 700 and causing it to undergo elastic deformation. Compared to a situation where there is no gap between the two, the display panel 120 and the first buffer medium 700 have a larger space to move, allowing for a longer time from when the external force acts on one of the display panel 120 and the first buffer medium 700 to when it fully acts on the other. This can further reduce the external force acting on the other, thereby further improving the buffering protection effect of the first buffer medium 700 on the display panel 120.

[0221] In some possible implementations, the minimum width of the gap between the first buffer medium 700 and the sidewall of the flexible display module 100 can be greater than 0 mm and less than or equal to 0.4 mm, for example, 1 mm, 2 mm, 3 mm, or 4 mm. In this way, while ensuring the buffering and protection effect of the first buffer medium 700 on the display panel 120, the bezel width is reduced, which helps to improve the sophistication of the foldable electronic device.

[0222] In some embodiments, such as Figure 9As shown, at least one portion of the first buffer medium 700 is fixedly connected to the inner wall of the corresponding second component 610, and another portion is fixedly connected to the inner wall of the corresponding first component 620. Along the first direction, a portion of at least one first buffer medium 700 is located inside the gap between the front surface of the flexible display module 100 and the inner wall of the second component 610.

[0223] In some scenarios, for example, the second component 610 of the frame member 600 deforms under external force, causing the second component 610 to collide with the front of the flexible display module 100, thereby damaging the front of the flexible display module 100. Therefore, by fixing a portion of the first buffer medium 700 to the inner sidewall of the second component 610, a portion of the first buffer medium 700 can be located inside the gap between the front of the flexible display module 100 and the inner sidewall of the second component 610, so that the first buffer medium 700 can provide buffer protection for the front of the flexible display module 100.

[0224] In some embodiments, at least one first buffer medium 700 may also be fixedly connected to the inner wall of the first component 620 and spaced apart from the inner wall of the second component 610.

[0225] When there are multiple first buffer media 700s, a portion of each first buffer media 700 can be fixedly connected to the inner wall of the corresponding second component 610, and another portion can be fixedly connected to the inner wall of the corresponding first component 620. Alternatively, all first buffer media 700s can be fixedly connected to the inner wall of the corresponding first component 620. Or, a portion of one first buffer media 700 can be fixedly connected to the inner wall of the corresponding second component 610, and another portion can be fixedly connected to the inner wall of the corresponding first component 620, while the remaining portion of the first buffer media 700s can all be fixedly connected to the inner wall of the corresponding first component 620.

[0226] In some possible implementations, along the first direction, the bottom surface of at least one first buffer medium 700 is lower than the bottom surface of the display panel 120, and the top surface of at least one first buffer medium 700 is higher than or flush with the top surface of the flexible display module 100.

[0227] Since the first component 620 may collide with the sidewall of the display panel 120, and the first component 620 of the frame member 600 may also collide with the layer structure of the flexible display module 100 located above the display panel 120 along the first direction, the first buffer medium 700 extends from a position below the bottom surface of the display panel 120 to a position above or flush with the top surface of the flexible display module 100 along the first direction. The first buffer medium 700 can provide buffer protection for the sidewall of the display panel 120 and the sidewall of the layer structure located above the display panel 120.

[0228] Alternatively, in some embodiments, along the first direction, the bottom surface of at least one first buffer medium 700 may be flush with or lower than the bottom surface of the flexible display module 100, and the top surface of at least one first buffer medium 700 may be flush with or higher than the top surface of the flexible display module 100.

[0229] Since the first component 620 may collide with the sidewall of the display panel 120, and the first component 620 of the frame member 600 may also collide with the layer structure of the flexible display module 100 located below the display panel 120 along the first direction, the first buffer medium 700 can extend from the bottom to the top of the flexible display module 100 along the first direction, and the first buffer medium 700 can provide buffer protection for the entire sidewall of the flexible display module 100.

[0230] In some possible implementations, such as Figure 9 As shown, the frame member 600 has a first receiving groove 621, and at least a portion of the first buffer medium member 700 is located inside the first receiving groove 621. Thus, in a direction perpendicular to the first direction, such as the second direction, at least a portion of the first buffer medium member 700 is embedded inside the first receiving groove 621. The first buffer medium member 700 occupies less space in the safety gap between the flexible display module 100 and the middle frame 220, allowing for a smaller safety gap between the flexible display module 100 and the middle frame 220. In a direction perpendicular to the first direction, the aesthetic refinement of the foldable electronic device can be further improved.

[0231] For example, the first receiving groove 621 may be disposed on the inner sidewall of the first component 620, or the first receiving groove 621 may be disposed on the inner sidewall of the second component 610 and the first component 620.

[0232] In some possible implementations, such as Figure 14As shown, the front surface of the flexible display module 100 can contact the first buffer medium 700. In this way, while the first buffer medium 700 provides buffer protection for the front surface of the flexible display module 100, the gap between the front surface of the flexible display module 100 and the second component 610 is small along the first direction, resulting in a smaller thickness of the foldable electronic device.

[0233] Of course, besides being able to contact the first buffer medium 700, the front side of the flexible display module 100 can also be used in some possible implementations, such as... Figure 9 As shown, the front side of the flexible display module 100 may not be in contact with the first buffer medium 700. Along the first direction, there is a gap between the first buffer medium 700 and the front side of the flexible display module 100.

[0234] When the second component 610 deforms due to external force, the first buffer medium 700, driven by the second component 610, first moves towards the front of the flexible display module 100 within the gap between the first buffer medium 700 and the front of the flexible display module 100, and then contacts the front of the flexible display module 100 and undergoes elastic deformation. Compared to a situation where there is no gap between the two, the first buffer medium 700 has a larger movable space, allowing the time from when the external force acts on the first buffer medium 700 to when it fully acts on the front of the flexible display module 100 to be longer. This further reduces the external force acting on the front of the flexible display module 100, thereby further improving the buffering protection effect of the first buffer medium 700 on the front of the flexible display module 100.

[0235] In some possible implementations, the minimum width of the gap between the first buffer medium 700 and the front surface of the flexible display module 100 in the first direction can be greater than 0 mm and less than or equal to 0.4 mm, for example, 1 mm, 2 mm, 3 mm, or 4 mm. In this way, while ensuring the buffering and protection effect of the first buffer medium 700 on the front surface of the flexible display module 100, it helps to reduce the thickness of the foldable electronic device.

[0236] In some embodiments, such as Figure 9 As shown, a portion of the first buffer medium 700 is disposed in the gap between the sidewall of the glass layer 1121 and the inner sidewall of the first component 620 along a direction perpendicular to the first direction.

[0237] In this way, the first buffer medium 700 can prevent the glass layer 1121 from directly colliding or rubbing with the first component 620, so as to avoid the glass layer 1121 from breaking, thereby achieving the buffer protection function of the glass layer 1121.

[0238] In some embodiments, at least one first buffer medium 700 is bonded to a corresponding frame member 600. Exemplarily, the first buffer medium 700 can be bonded to the frame member 600 using adhesive backing or spot bonding. This reduces the difficulty of connecting the first buffer medium 700 to the frame member 600, thereby reducing the manufacturing cost of the foldable electronic device.

[0239] Of course, in addition to being bonded to the frame member 600, in some embodiments, at least one first buffer medium 700 and the corresponding frame member 600 are integrally formed. The first buffer medium 700 and the frame member 600 can be prefabricated by an integral molding process, thereby simplifying the assembly process of foldable electronic devices.

[0240] In some possible implementations, at least one first buffer medium element 700 includes a plurality of first buffer medium bodies arranged circumferentially spaced along the flexible display module 100, that is, there is a gap between two adjacent first buffer medium bodies. Exemplarily, at least one frame element 600 is fixedly connected to a plurality of first buffer medium bodies, for example, each frame element 600 is fixedly connected to a plurality of first buffer medium bodies.

[0241] In this way, there is a gap between two adjacent first buffer media, which can reduce the design difficulty of the gap between the inner sidewall of the frame 600 and the display panel 120, and can adapt to the frame 600 with a complex structure.

[0242] The number of the first buffer media can be two, five, seven, or ten.

[0243] When there are multiple first buffer media, the structures of each first buffer media can be the same, or some parts can be the same while others are different.

[0244] Of course, the first buffer medium 700 may include not only multiple first buffer media, but also, in some possible implementations, such as Figure 9 As shown, the first buffer medium 700 may not include multiple first buffer media; in other words, at least one first buffer medium 700 can be a single integral structure. This reduces the assembly steps of the foldable electronic device and helps improve the assembly efficiency of the foldable electronic device.

[0245] In some possible implementations, in at least one first buffer medium 700, the at least one first buffer medium body can be a solid structure, and / or, the at least one first buffer medium body can have at least one first sealed cavity 710, and / or, the at least one first buffer medium body has at least one first through hole 720, and / or, the at least one first buffer medium body has at least one first groove 730. Such an arrangement can further enhance the buffering and protective effect of the first buffer medium body on the display panel 120.

[0246] Figure 15 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0247] In the preceding description, the border component 600 is constituted by the first component 620 and the second component 610; however, in some possible implementations, such as Figure 15 As shown, the frame member 600 can also omit the second component 610. In this case, the frame member 600 is formed by the first component 620. With this configuration, compared to the frame member 600 having both the first component 620 and the second component 610, when the frame member 600 only has the first component 620, the frame width of the foldable electronic device along the direction perpendicular to the first direction is the distance between the front edge of the flexible display module 100 and the outer wall of the middle frame 20, for example... Figure 15 As shown in L3, where L3 is smaller than L2. Therefore, the dimensions of the frame member 600 perpendicular to the first direction can be further reduced, thereby further reducing the frame width of the foldable electronic device and further improving its aesthetic appeal.

[0248] When the frame member 600 is formed by the first component 620, the relevant settings of the first buffer medium 700 can be referred to the relevant settings of the first component 620 and the first buffer medium 700 described above.

[0249] When the frame member 600 is configured solely by the first component 620, the front surface of the flexible display module 100 can be flush with or lower than the front surface of the first component 620. Additionally, the front surface of the first buffer medium 700 can be flush with or lower than the front surface of the first component 620. Furthermore, the first buffer medium 700 can contact or be spaced from the sidewall of the flexible display module 100. When the first buffer medium 700 contacts the sidewall of the flexible display module 100, it can fill the gap between the flexible display module 100 and the inner sidewall of the first component 620, further enhancing the sophistication of the foldable electronic device.

[0250] Figure 16This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0251] In some possible implementations, the foldable electronic device also includes a protective block 800, wherein, as Figure 2 As shown, each pivot assembly 210 is connected to two protective blocks 800. Along the third direction, the two protective blocks 800 are fixedly connected to both ends of the pivot assembly 210. Along the second direction, the protective blocks 800 can be disposed between two adjacent middle frames 220, or, along the third direction, the protective blocks 800 can be disposed on the side of the inner sidewall of the middle frame 220.

[0252] like Figure 16 As shown, the protective block 800 includes an end plate portion 810 and a protrusion portion 820. The two ends of the end plate portion 810 along a first direction are fixedly connected to the protrusion portion 820 and the rotating shaft assembly 210, respectively. Along the first direction (e.g., ... Figure 16 In the Z direction, the flexible display module 100 is located between the hinge assembly 210 and the protrusion portion 820. Along the first direction, the projection of the flexible display module 100 does not coincide with the projection of the end plate portion 810. Along the third direction (e.g., in the Z direction), the flexible display module 100 is located between the hinge assembly 210 and the protrusion portion 820. Figure 16 (in the Y direction), there is a gap between the inner sidewall of the end plate portion 810 and the sidewall of the flexible display module 100.

[0253] Specifically, the end plate portion 810 of the protective block 800 can be fixedly connected to the rotating shaft assembly 210 by means of adhesive dispensing, screw connection, etc., to achieve a fixed connection between the protective block 800 and the rotating shaft assembly 210. The protrusion portion 820 can protect the front of the flexible display module 100, and the end plate portion 810 can protect the side wall of the flexible display module 100. Thus, the protective block 800 can protect the edge of the flexible display module 100.

[0254] In some possible implementations, such as Figure 16 As shown, the foldable electronic device also includes at least two elastically deformable second buffer media 900. Each second buffer media 900 corresponds to a protective block 800, and at least a portion of each second buffer media 900 is fixedly connected to the inner sidewall of the end plate portion 810 of the corresponding protective block 800. Along a third direction, at least a portion of the second buffer media 900 is disposed within the gap between the sidewall of the display panel 120 and the inner sidewall of the end plate portion 810.

[0255] By arranging an elastically deformable second buffer medium 900 in the gap between the side wall of the display panel 120 and the inner side wall of the end plate portion 810, when an external force drives one of the flexible display module 100 and the protective block 800 to move towards the other, the display panel 120 or the protective block 800 squeezes the second buffer medium 900, causing the second buffer medium 900 to deform. The second buffer medium 900 plays a buffering role, which can prevent the side wall of the display panel 120 from having direct and hard friction or collision with the inner side wall of the protective block 800, and can prevent damage to the display panel 120.

[0256] Specifically, since the second buffer medium 900 can deform, according to the momentum theorem, the second buffer medium 900 can prolong the displacement time of one of the display panel 120 and the end plate portion 810 through its own compressive deformation, thereby prolonging the duration of the external force and reducing the magnitude of the external force acting on the other of the display panel 120 and the end plate portion 810. This prevents direct, hard friction or collision between the sidewall of the display panel 120 and the inner sidewall of the protective block 800, thus avoiding damage to the display panel 120. In addition, since the deformation of the second buffer medium 900 is elastic, it can return to its original shape when the external force disappears, allowing the second buffer medium 900 to provide long-term buffer protection for the display panel 120.

[0257] For example, when an external force is applied to the flexible display module 100 and causes it to bend, misalignment occurs between the various layers of the flexible display module 100 in the third direction. The misaligned layers will move towards the second buffer medium 900 and compress it. As another example, when the protective block 800 deforms under external force, such as when a foldable electronic device is bumped or dropped, the impact force will cause the protective block 800 to deform, which will cause the second buffer medium 900 to move towards the display panel 120 and be compressed.

[0258] Furthermore, since the second buffer medium 900 can provide better buffer protection for the sidewall of the display panel 120, the gap between the sidewall of the display panel 120 and the protective block 800 does not need to be a large gap design. The gap between the sidewall of the display panel 120 and the inner sidewall of the protective block 800 can be a small gap design, thereby reducing the size of the protective block 800 in the third direction, which in turn can further reduce the bezel width of the foldable electronic device and further improve the appearance refinement of the foldable electronic device.

[0259] In some possible implementations, the second buffer medium 900 may be made of at least one of materials such as foam, silicone, TPU and TPE.

[0260] In some embodiments, such as Figure 16 As shown, at least one second buffer medium 900 can be a solid structure; for example, all second buffer mediums 900 are solid structures. This configuration allows the second buffer mediums 900 to provide cushioning and protection. Furthermore, it reduces the manufacturing difficulty of the second buffer mediums 900, which helps to lower the cost of foldable electronic devices.

[0261] Figure 17 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0262] In some embodiments, such as Figure 17 As shown, at least one second buffer medium 900 has at least one second sealed cavity 910. For example, each second buffer medium 900 has one or more second sealed cavities 910. When a second buffer medium 900 has a second sealed cavity 910, the second sealed cavity 910 can be a cavity that is not connected to the outside of the second buffer medium 900. When an external force is applied to either the flexible display module 100 or the protective block 800, the second buffer medium 900 is compressed and undergoes elastic deformation. The second sealed cavity 910 allows the second buffer medium 900 to have a larger deformation space, which can prolong the time of application of the external force, thereby reducing the external force applied to the other of the flexible display module 100 and the protective block 800, and improving the buffering and protection effect of the second buffer medium 900 on the display panel 120.

[0263] The second buffer medium 900 may have multiple or one second sealed cavity 910. When there are multiple second sealed cavities 910, the multiple second sealed cavities 910 can be arranged at intervals.

[0264] The number of second buffer media 900 can be multiple or one. When there are multiple second buffer media 900, the number of second sealed cavities 910 of each second buffer media 900 is the same, or, a portion of the multiple second buffer media 900 has the same number of second sealed cavities 910, while another portion has a different number.

[0265] The embodiments of this application do not restrict the arrangement direction of the plurality of second sealed cavities 910. For example, the plurality of second sealed cavities 910 can be arranged along the first direction or in a direction that has an angle with the first direction.

[0266] Figure 18 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0267] In some embodiments, such as Figure 18As shown, at least one second buffer medium 900 has at least one second through hole 920. For example, each second buffer medium 900 has one or more second through holes 920. When the second buffer medium 900 has a second through hole 920, the second through hole 920 is a hole that penetrates the solid portion of the second buffer medium 900. When an external force is applied to either the flexible display module 100 or the protective block 800, the second buffer medium 900 is compressed and undergoes elastic deformation. The second through hole 920 allows the second buffer medium 900 to have a larger deformation space, which can prolong the time of application of the external force, thereby reducing the external force applied to the other of the flexible display module 100 and the protective block 800, and improving the buffering and protection effect of the second buffer medium 900 on the display panel 120.

[0268] The second buffer medium 900 may have multiple or one second through hole 920. When there are multiple second through holes 920, the multiple second through holes 920 can be arranged at intervals.

[0269] The number of second buffer media 900 can be multiple or one. When there are multiple second buffer media 900, the number of second through holes 920 of each second buffer media 900 is the same, or, a portion of the multiple second buffer media 900 has the same number of second through holes 920, while another portion has a different number.

[0270] The embodiments of this application do not restrict the arrangement direction of the plurality of second through holes 920. For example, the plurality of second through holes 920 can be arranged along the first direction or in a direction having an angle with the first direction.

[0271] The specific location of the second through hole 920 is not limited in this embodiment. For example, the cross-sectional shape of the second through hole 920 can be a regular shape such as an ellipse, circle, quadrilateral or pentagon, or it can be an irregular shape.

[0272] The cross-sectional shape of the second through hole 920 is not limited in this embodiment. For example, the cross-sectional shape of the second through hole 920 can be elliptical, circular, quadrilateral or pentagonal, etc.

[0273] Figure 19 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application. Figure 20 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0274] In some embodiments, such as Figure 19 or Figure 20As shown, at least one second buffer medium 900 has at least one second groove 930. For example, each second buffer medium 900 has one or more second grooves 930. When the second buffer medium 900 has a second groove 930, the second groove 930 is a groove disposed on the surface of the second buffer medium 900. When an external force is applied to either the flexible display module 100 or the protective block 800, the second buffer medium 900 is compressed and undergoes elastic deformation. The second groove 930 allows the second buffer medium 900 to have a larger deformation space, which can prolong the time of application of the external force, thereby reducing the external force applied to the other of the flexible display module 100 and the protective block 800, and improving the buffering and protection effect of the second buffer medium 900 on the display panel 120.

[0275] The number of second buffer media 900 can be multiple or one. When there are multiple second buffer media 900, the number of second grooves 930 in each second buffer media 900 is the same, or, a portion of the multiple second buffer media 900 have the same number of second grooves 930, while another portion have different numbers.

[0276] Among them, such as Figure 19 As shown, the opening of the second groove 930 can face the flexible display module 100, or, as... Figure 20 As shown, the opening of the second groove 930 can face the protective block 800.

[0277] The second buffer medium 900 may have multiple or one second groove 930. When there are multiple second grooves 930, each second groove 930 faces the same direction, or, some of the second grooves 930 have the same groove opening direction, while the groove openings of other parts do not face the same direction.

[0278] The embodiments of this application do not limit the arrangement direction of the plurality of second grooves 930. For example, the plurality of second grooves 930 can be arranged along the first direction or in a direction having an angle with the first direction.

[0279] In some embodiments, at least one second buffer medium 900 has one of a second sealed cavity 910, a second through hole 920, and a second groove 930.

[0280] In some embodiments, at least one second buffer medium 900 may simultaneously have at least two of the second sealed cavity 910, the second through hole 920, and the second groove 930. For example, each second buffer medium 900 may simultaneously have the second sealed cavity 910 and the second groove 930. Thus, the second buffer medium 900 may have different types of buffer structures.

[0281] Figure 21This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0282] In some embodiments, such as Figure 21 As shown, the sidewall of the flexible display module 100 can contact the second buffer medium 900, and thus, the sidewall of the display panel 120 can also contact the second buffer medium 900. In this way, while the second buffer medium 900 provides cushioning protection for the display panel 120, the gap between the flexible display module 100 and the end plate portion 810 is smaller, further enhancing the refined appearance of the foldable electronic device along the third direction.

[0283] Of course, in addition to contacting the second buffer medium 900, the sidewalls of the flexible display module 100 can also, in some embodiments, such as... Figure 16 As shown, the sidewall of the flexible display module 100 may not be in contact with the second buffer medium 900. Along the third direction, there is a gap between the second buffer medium 900 and the sidewall of the flexible display module 100.

[0284] When an external force is applied to either the flexible display module 100 or the protective block 800, the display panel 120 and the second buffer medium 900 will first move within the gap between the second buffer medium 900 and the sidewall of the flexible display module 100. Only then will the second buffer medium 900 come into contact with the other of the two and compress it, causing elastic deformation. Compared to a situation where there is no gap between them, the display panel 120 and the second buffer medium 900 have a larger movable space, allowing for a longer time from the application of external force to the complete application of the force to the other. This further reduces the force applied to the other, thereby enhancing the buffering protection effect of the second buffer medium 900 on the display panel 120.

[0285] In some possible implementations, the minimum width of the gap between the second buffer medium 900 and the sidewall of the flexible display module 100 can be greater than 0 mm and less than or equal to 0.4 mm, for example, 1 mm, 2 mm, 3 mm, or 4 mm. In this way, while ensuring the buffering and protection effect of the second buffer medium 900 on the display panel 120, the bezel width is reduced, which helps to improve the sophistication of the foldable electronic device.

[0286] In some embodiments, such as Figure 16As shown, at least one part of the second buffer medium 900 is fixedly connected to the inner wall of the corresponding protrusion portion 820, and another part is fixedly connected to the inner wall of the corresponding end plate portion 810. Along the first direction, a portion of at least one second buffer medium 900 is located inside the gap between the front surface of the flexible display module 100 and the inner wall of the protrusion portion 820.

[0287] In some scenarios, for example, the protrusion 820 of the protective block 800 deforms under external force, causing the protrusion 820 to collide with the front of the flexible display module 100, thereby damaging the front of the flexible display module 100. Therefore, by partially arranging the second buffer medium 900 between the front of the flexible display module 100 and the inner sidewall of the protrusion 820, the second buffer medium 900 can also provide buffer protection for the front of the flexible display module 100.

[0288] In some embodiments, at least one second buffer medium 900 may also be fixedly connected to the inner sidewall of the end plate portion 810 and spaced apart from the inner sidewall of the protrusion portion 820.

[0289] When there are multiple second buffer media 900, a portion of each second buffer media 900 can be fixedly connected to the inner wall of the corresponding protrusion portion 820, and another portion can be fixedly connected to the inner wall of the corresponding end plate portion 810. Alternatively, all second buffer media 900 can be fixedly connected to the inner wall of the corresponding end plate portion 810. Or, a portion of one type of second buffer media 900 can be fixedly connected to the inner wall of the corresponding protrusion portion 820, and another portion can be fixedly connected to the inner wall of the corresponding end plate portion 810, while the remaining portion of second buffer media 900 can be fixedly connected to the inner wall of the corresponding end plate portion 810.

[0290] In some possible implementations, along the first direction, the bottom surface of at least one second buffer medium 900 is lower than the bottom surface of the display panel 120, and the top surface of at least one second buffer medium 900 is higher than or flush with the top surface of the flexible display module 100.

[0291] Since the end plate portion 810 may collide with the sidewall of the display panel 120, and the end plate portion 810 of the protective block 800 may also collide with the layer structure of the flexible display module 100 located above the display panel 120 along the first direction, the second buffer medium 900 extends from a position below the bottom surface of the display panel 120 to a position above or flush with the top surface of the flexible display module 100 along the first direction. The second buffer medium 900 can provide buffer protection for the sidewall of the display panel 120 and the sidewall of the layer structure located above the display panel 120, which can further improve the reliability of the flexible display module 100.

[0292] Alternatively, in some embodiments, along the first direction, the bottom surface of at least one second buffer medium 900 may be flush with or lower than the bottom surface of the flexible display module 100, and the top surface of at least one second buffer medium 900 may be flush with or higher than the top surface of the flexible display module 100.

[0293] Since the end plate portion 810 may collide with the side wall of the display panel 120, and the end plate portion 810 of the protective block 800 may also collide with the layer structure of the flexible display module 100 located below the display panel 120 along the first direction, the second buffer medium 900 can extend from the bottom to the top of the flexible display module 100 along the first direction, and the second buffer medium 900 can provide buffer protection for the entire side wall of the flexible display module 100.

[0294] In some possible implementations, such as Figure 16 As shown, the protective block 800 has a second receiving groove 830, and at least a portion of the second buffer medium 900 is located inside the second receiving groove 830. Thus, along a third direction, at least a portion of the second buffer medium 900 is embedded inside the second receiving groove 830. The second buffer medium 900 occupies less space in the gap between the flexible display module 100 and the protective block 800, allowing for a smaller gap between the flexible display module 100 and the protective block 800. Along a third direction, this further enhances the aesthetic refinement of the foldable electronic device.

[0295] For example, the second receiving groove 830 may be provided on the inner sidewall of the end plate portion 810, or the second receiving groove 830 may be provided on the inner sidewall of the end plate portion 810 and the protrusion portion 820.

[0296] In some possible implementations, such as Figure 21 As shown, the front surface of the flexible display module 100 can contact the second buffer medium 900. In this way, the second buffer medium 900 can not only provide cushioning protection for the front surface of the flexible display module 100, but also reduce the gap between the front surface of the flexible display module 100 and the protrusion portion 820, which helps to reduce the thickness of the foldable electronic device and facilitates the realization of a thinner and lighter design for the foldable electronic device.

[0297] Of course, besides contacting the second buffer medium 900, the front side of the flexible display module 100 can also be used in some possible implementations, such as... Figure 16 As shown, the front side of the flexible display module 100 may not be in contact with the second buffer medium 900. Along the first direction, at least one second buffer medium 900 has a gap with the front side of the flexible display module 100.

[0298] When the protrusion 820 deforms due to external force, the second buffer medium 900, driven by the protrusion 820, first moves towards the front of the flexible display module 100 within the gap between the second buffer medium 900 and the front of the flexible display module 100, and then contacts the front of the flexible display module 100 and undergoes elastic deformation. Compared to a situation where there is no gap between the two, the second buffer medium 900 has a larger movable space, allowing the time from when the external force acts on the second buffer medium 900 to when it fully acts on the front of the flexible display module 100 to be longer. This further reduces the external force acting on the front of the flexible display module 100, thereby further improving the buffering protection effect of the second buffer medium 900 on the front of the flexible display module 100.

[0299] In some possible implementations, the minimum width of the gap between the second buffer medium 900 and the front surface of the flexible display module 100 in the first direction can be greater than 0 mm and less than or equal to 0.4 mm, for example, 1 mm, 2 mm, 3 mm, or 4 mm. In this way, while ensuring the buffering and protection effect of the second buffer medium 900 on the front surface of the flexible display module 100, it helps to reduce the thickness of the foldable electronic device.

[0300] In some embodiments, such as Figure 16 As shown, along a third direction, a portion of the second buffer medium 900 is disposed in the gap between the sidewall of the glass layer 1121 and the inner sidewall of the end plate portion 810.

[0301] In this way, the second buffer medium 900 can prevent the glass layer 1121 from directly colliding or rubbing with the end plate portion 810, so as to avoid the glass layer 1121 from breaking, thereby achieving the buffer protection function of the glass layer 1121.

[0302] In some embodiments, at least one second buffer medium 900 is bonded to a corresponding protective block 800. Exemplarily, the second buffer medium 900 can be bonded to the protective block 800 using adhesive backing or dispensing. This reduces the difficulty of connecting the second buffer medium 900 to the protective block 800, thereby reducing the manufacturing cost of foldable electronic devices.

[0303] Of course, in addition to being bonded to the protective block 800, in some embodiments, at least one second buffer medium 900 and the corresponding protective block 800 are integrally formed. The second buffer medium 900 and the protective block 800 can be pre-fabricated using an integral molding process, thereby simplifying the assembly process of foldable electronic devices. Furthermore, this improves the reliability of the connection between the protective block 800 and the second buffer medium 900.

[0304] In some possible implementations, at least one second buffer medium element 900 includes a plurality of second buffer medium bodies arranged circumferentially spaced along the flexible display module 100, that is, there is a gap between two adjacent second buffer medium bodies. Exemplarily, at least one protective block 800 is fixedly connected to a plurality of second buffer medium bodies, for example, each protective block 800 is fixedly connected to a plurality of second buffer medium bodies.

[0305] In this way, there is a gap between two adjacent second buffer media, which can reduce the design difficulty of the gap between the inner wall of the protection block 800 and the display panel 120, and can be adapted to the complex structure of the protection block 800.

[0306] The number of the second buffer media can be two, five, or ten.

[0307] When there are multiple second buffer media, the structures of each second buffer media can be the same, or some parts can be the same while others are different.

[0308] Of course, the second buffer medium 900 may include multiple second buffer media in some possible implementations, such as Figure 16 As shown, the second buffer medium 900 may also not include multiple second buffer media; in other words, at least one second buffer medium 900 can be a single integral structure. This reduces the assembly steps in foldable electronic devices and helps improve assembly efficiency.

[0309] In some possible implementations, at least one second buffer medium 900 may be a solid structure, and / or may have at least one second sealed cavity 910, and / or may have at least one second through hole 920, and / or may have at least one second groove 930. This configuration can further enhance the buffering and protective effect of the second buffer medium on the display panel 120.

[0310] Figure 22 This is another structural schematic diagram of the foldable electronic device provided in the embodiments of this application.

[0311] In the preceding description, the protective block 800 is constructed by an end plate portion 810 and a protrusion portion 820. However, in some possible implementations, such as Figure 22As shown, the protective block 800 can also omit the protrusion 820, in which case the protective block 800 is formed by the end plate 810. With this configuration, compared to the protective block 800 having both the end plate 810 and the protrusion 820, when the protective block 800 only has the end plate 810, the bezel width of the foldable electronic device along the direction perpendicular to the first direction is the distance between the sidewall of the flexible display module 100 and the outer sidewall of the end plate 810 of the protective block 800. Therefore, it can be seen that the protective block 800 in the third direction (e.g., Figure 22 The dimensions in the Y direction can be adjusted to further reduce the bezel width of foldable electronic devices, thereby enhancing their aesthetic appeal.

[0312] When the protective block 800 is constituted solely by the end plate portion 810, the relevant settings of the second buffer medium 900 can be referred to the relevant settings of the end plate portion 810 and the second buffer medium 900 described above.

[0313] When the protective block 800 is configured solely through the end plate portion 810, the front surface of the flexible display module 100 can be flush with or lower than the front surface of the end plate portion 810. Additionally, the front surface of the second buffer medium 900 can be flush with or lower than the front surface of the end plate portion 810. Furthermore, the second buffer medium 900 can contact or be spaced from the sidewall of the flexible display module 100. When the second buffer medium 900 contacts the sidewall of the flexible display module 100, it can fill the gap between the flexible display module 100 and the inner sidewall of the end plate portion 810, further enhancing the sophistication of the foldable electronic device.

[0314] In summary, by providing the first buffer medium 700 or the second buffer medium 900, the flexible display module 100 can be buffered and protected, thereby reducing the bezel width of the foldable electronic device. Therefore, the foldable electronic device can have both the first buffer medium 700 and the second buffer medium 900, or it can have only one of the first buffer medium 700 and the second buffer medium 900.
