[0001] The present application relates to the technical field of electronic devices, and in particular to a foldable electronic device. Background Art

[0002] A foldable electronic device includes a hinge, a screen and a housing, wherein the screen may be a flexible screen for displaying images, videos, etc., and the screen may be bent around the hinge. During the bending process of the screen, the inner side of the bending area is compressed and the outer side is stretched, and long-term use may cause the bending area of ​​the screen to break. Utility Model Content

[0003] The purpose of the present application is to provide a foldable electronic device to solve the problem in the prior art that the foldable electronic device is prone to breakage in the bending area during use.

[0004] According to a first aspect of the present application, there is provided a foldable electronic device, comprising: a shell, the shell comprising a first shell and a second shell distributed along the width direction of the foldable electronic device; a rotating shaft, the rotating shaft being located between the first shell and the second shell; a screen, the screen comprising two plane areas and a bending area, along the width direction of the foldable electronic device, the bending area is located between the two plane areas, the bending area covers the rotating shaft, and the two plane areas respectively cover the first shell and the second shell; wherein the foldable electronic device also comprises a connecting member, along the thickness direction of the foldable electronic device, the first shell is connected to the plane area through the connecting member, and / or the second shell is connected to the plane area through the connecting member; the connecting member is a rubber material capable of elastic deformation.

[0005] In this embodiment, the connecting member is capable of elastic deformation. When the first connecting end of the connecting member is subjected to an external force along the width direction of the screen toward the bending zone, the first connecting end is capable of moving toward the bending zone relative to the second connecting end, so that the connecting member is in an elastically deformed state, that is, the first connecting end connected to the plane area is closer to the bending zone than the second connecting end connected to the shell, thereby releasing the stress of the bending zone in the bending state through the elastic deformation of the connecting member, thereby reducing the risk of the bending zone breaking in the bending state.

[0006] In a specific embodiment, the connecting piece is made of organic silicone.

[0007] In this embodiment, the silicone sealant has good high and low temperature resistance and a temperature resistance range of -45°C to 350°C, so that the reduction in the elastic modulus of the connector in a low temperature environment is small, that is, the elastic modulus of the connector in a low temperature environment is closer to the elastic modulus in a normal temperature environment. When the foldable electronic device is used in a normal temperature and low temperature environment, the elastic deformation of the connector when subjected to tension along the width direction of the screen is large, so that the first connecting end can move toward the bending zone driven by the plane zone, thereby releasing part of the tensile stress in the bending zone, reducing the risk of breakage in the bending zone, and extending the service life of the screen.

[0008] A second aspect of the present application provides another foldable electronic device, which includes: a shell, the shell including a first shell and a second shell distributed along the width direction of the foldable electronic device; a rotating shaft, the rotating shaft is located between the first shell and the second shell; a screen, the screen including two plane areas and a bending area, along the width direction of the foldable electronic device, the bending area is located between the two plane areas, the bending area covers the rotating shaft, and the two plane areas cover the first shell and the second shell respectively; wherein the foldable electronic device also includes a connecting member, along the thickness direction of the foldable electronic device, the first shell and the plane area are connected through the connecting member, and / or the second shell and the plane area are connected through the connecting member; the connecting member is a magnet.

[0009] In this embodiment, when the foldable electronic device is used in a low temperature environment and is in a bent state, the tensile stress in the bending zone caused by the influence of the low temperature increases, so that the tensile force on the inner side of the planar area along the width direction of the screen also increases accordingly, while the magnetism of the magnet is little affected by the low temperature, that is, in a low temperature environment, the magnetic forces of the connector on the planar area and the shell are close, and under the action of the larger tensile force of the bending zone on the planar area, the inner side of the planar area can overcome the magnetic attraction between it and the connector and move toward the bending zone. At this time, the planar area moves toward the bending zone relative to the connector; or, under the action of the tensile force, the magnetic attraction between the outer side of the planar area and the shell can be overcome to make the planar area move toward the bending zone. At this time, the planar area drives the connector to move toward the bending zone relative to the shell, thereby reducing the tensile stress in the bending zone and reducing the risk of the bending zone breaking in a low temperature environment.

[0010] In a specific embodiment, the plane area includes a first plane area and a second plane area located on both sides of the rotating shaft, the connecting member includes a first connecting member and a second connecting member, the first plane area is connected to the first shell through the first connecting member, and the second plane area is connected to the second shell through the second connecting member; the ratio of the area S1 of the first connecting member to the area S2 of the first plane area satisfies: 0.4≤S1 / S2≤0.8, and / or the ratio of the area S3 of the second connecting member to the area S4 of the second plane area satisfies: 0.4≤S3 / S4≤0.8.

[0011] In this embodiment, a connecting member is arranged between the first plane area and the first shell, and a connecting member is arranged between the second plane area and the second shell. At this time, the ratio of the area S1 of the first connecting member to the area S2 of the first plane area satisfies: 0.4≤S1 / S2≤0.8, so that the first connecting member has a high connection reliability between the first plane area and the first shell, and the ratio of the area S3 of the second connecting member to the area S2 of the second plane area satisfies: 0.4≤S3 / S4≤0.8, so that the second connecting member has a high connection reliability between the second plane area and the second shell.

[0012] In a specific embodiment, the plane area includes a first plane area and a second plane area located on both sides of the rotating shaft, and the connecting member includes a first connecting member and a second connecting member; along the width direction of the screen, at least two first connecting members are arranged between the first shell and the first plane area, and at least two second connecting members are arranged between the second shell and the second plane area.

[0013] In this embodiment, it is not necessary to cover the entire first plane area, so that the amount of connectors used can be reduced, the structure of the foldable electronic device can be simplified, and the cost can be reduced. It can also reduce the weight of the screen and improve the portability of the foldable electronic device. When the foldable electronic device is in a folded state, the two first connectors can both be elastically deformed, and the first connecting ends of the two first connectors can both move toward the bending zone along the width direction of the screen, and drive the first plane area to move toward the bending zone, thereby releasing part of the tensile stress in the bending zone. At the same time, the two second connectors can both be elastically deformed, and the first connecting ends of the two second connectors can both move toward the bending zone along the width direction of the screen, and drive the second plane area to move toward the bending zone, thereby releasing part of the tensile stress in the bending zone.

[0014] In a specific embodiment, the plane area further includes an outer end portion, and along the width direction of the foldable electronic device, a minimum distance W1 between the connecting member and the outer end portion satisfies W1≤5mm.

[0015] In this embodiment, the minimum distance W1 between the connecting member and the outer end of the plane area satisfies W1≤5mm, so that at least one connecting member is close to the outer end of the plane area, thereby improving the connection reliability between the outer end of the plane area and the shell, avoiding the outer end from warping under the action of external force during use, and extending the service life.

[0016] In a specific embodiment, the connecting member includes at least two first connecting segments and at least two second connecting segments, the first connecting segments extend along the length direction of the foldable electronic device, and the second connecting segments extend along the width direction of the foldable electronic device.

[0017] In this embodiment, the connector includes at least two first connecting sections and two second connecting sections, that is, the plane area and the shell are connected by the first connecting section extending along the length direction of the foldable electronic device, and are also connected by the second connecting section extending along the width direction of the foldable electronic device, which can improve the connection reliability between the plane area and the shell and avoid cracking during use. The first connecting section extends along the length direction of the foldable electronic device, and the second connecting section extends along the width direction of the foldable electronic device, so that a part of the connector is located between the plane area and the shell, and there are parts of the connector in both the length direction and the width direction, so that the plane area remains flat.

[0018] In a specific embodiment, the first connecting section and the second connecting section form a rectangular structure.

[0019] In this embodiment, the first connecting section and the second connecting section form a rectangular structure, so that the plane area and the shell can be in contact with the connecting piece at all circumferential locations, which can improve the connection reliability between the plane area and the shell. At the same time, it can improve the sealing between the plane area and the shell, reduce dust and other impurities from entering the accommodation space between the shell and the plane area, and reduce the risk of screen damage.

[0020] In a specific embodiment, along the width direction of the foldable electronic device, there is a gap between the connecting member and the rotating shaft.

[0021] In this embodiment, when an elastically deformable adhesive is used as a connecting member, there is a gap between the first connecting member and the rotating shaft, and a gap between the second connecting member and the rotating shaft along the width direction of the screen. The gap provides space for the first connecting member and the second connecting member to undergo elastic deformation.

[0022] When magnets are used as connectors, there is a gap between the first connector and the rotating shaft and a gap between the second connector and the rotating shaft in the width direction of the screen. The gap provides space for the first connector and the second connector to move toward the bending zone along the length direction of the screen.

[0023] In a specific embodiment, the minimum gap between the connecting member and the rotating shaft is 3mm≤W2≤5mm.

[0024] In the present embodiment, the minimum gap W2 between the connector and the rotating shaft satisfies 3mm≤W2≤5mm. For example, W2 can be 3mm, 4mm, 5mm, etc. W2 should not be too large or too small. When it is too large, the distance between the connector and the rotating shaft is too large, which reduces the connection reliability between the end of the plane area facing the bending zone and the shell. When it is too small, the distance between the connector and the rotating shaft is too small, and when the connector moves toward the bending zone driven by the plane area, it is easy to interfere with the rotating shaft. In the present embodiment, when 3mm≤W2≤5mm, while ensuring the connection reliability between the end position of the plane area facing the bending zone and the shell, it can provide space for the connector to move toward the bending zone driven by the plane area, so as to release the stress in the bending zone and reduce the risk of fracture in the bending zone.

[0025] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] like Figure 1 As shown, Figure 1 : is a schematic diagram of the structure of a foldable electronic device 1 in a specific embodiment. The foldable electronic device 1 includes any device with a foldable screen function, such as a mobile phone, a tablet computer, a personal digital assistant (PDA), a laptop computer, a car computer, a foldable display device, a foldable display screen, a wearable device, etc. The embodiment of the present application does not impose any special restrictions on the specific form of the above-mentioned foldable electronic device 1. For the convenience of explanation, the following description is based on the foldable electronic device 1 being a foldable mobile phone as an example. The foldable electronic device 1 of the present application is introduced in the following with a specific embodiment.

[0060] The foldable electronic device 1 includes a shaft 13, a housing 12, and a screen 11 mounted on the housing 12. The housing 12 may include a first housing 121 and a second housing 122 distributed along the width direction X of the screen 11. The shaft 13 is located between the first housing 121 and the second housing 122, and the first housing 121 and the second housing 122 are both connected to the shaft 13. The first housing 121 and the second housing 122 can rotate relative to each other along the shaft 13. Among them, the screen 11 can be a flexible screen, covering the first housing 121 and the second housing 122, and the screen 11 is used to display images, videos, etc. The specific type of the screen 11 of the present application is not limited. For example, the flexible screen can be an organic light-emitting diode (OLED) display screen. For example, the screen 11 can be fixedly connected (for example, bonded) to the first housing 121 and the second housing 122, and cover the shaft 13. The first shell 121 and the second shell 122 can be bent along the shaft 13, thereby driving the screen 11 to bend around the shaft 13, so that the screen 11 has a Figure 1 The expanded state shown and Figure 2 The bent state shown.

[0061] like Figure 2 As shown, Figure 2 for Figure 1 The schematic diagram of the structure of the foldable electronic device 1 in the folded state. The screen 11 includes a plane area 111 and a bending area 112. Along the width direction X of the screen 11, the plane area 111 is located on both sides of the bending area 112. The two plane areas 111 are fixedly connected to the first shell 121 and the second shell 122 respectively, and the bending area 112 covers the rotating shaft 13. At this time, the inner side of the bending area 112 is the side facing the rotating shaft 13, and the inner side of the plane area 111 is the side fixedly connected to the first shell 121 and the second shell 122.

[0062] like Figure 3 As shown, Figure 3 for Figure 1 The structure diagram of the bending area 112 of the middle screen in the unfolded state and the folded state. When the screen is in the unfolded state, the length of the outer side of the bending area 112 is L1, and the length of the inner side is L2. At this time, L1 = L2, that is, in the unfolded state, the length of each part of the screen is the same, and the screen is not stretched or compressed; when the screen is driven by the shaft along Figure 3 As shown by the arrow, after folding, the length L2 of the inner side of the bending area 112 becomes L4, and the length L1 of the outer side becomes L3, L4<L2, and L3>L1, that is, during the folding process, the inner side of the bending area 112 is compressed and the outer side is stretched. When in the bent state, tensile stress will be generated inside the bending area 112, and there is a risk of breakage during long-term use.

[0063] To solve this technical problem, the present application embodiment provides a foldable electronic device 1, such as Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of a foldable electronic device 1 provided in the present application in a specific embodiment, wherein the foldable electronic device 1 includes a screen 11, a housing 12, and a hinge 13, wherein the housing 12 may include a first housing 121 and a second housing 122 distributed along the width direction X of the screen 11, the hinge 13 is located between the first housing 121 and the second housing 122, and the first housing 121 and the second housing 122 are both connected to the hinge 13, and the first housing 121 and the second housing 122 can rotate relative to each other along the hinge 13. The screen 11 includes a plane area 111 and a bending area 112, along the width direction X of the screen 11, the plane area 111 is located on both sides of the bending area 112, the two plane areas 111 are fixedly connected to the first housing 121 and the second housing 122, respectively, and the bending area 112 covers the hinge 13. When the foldable electronic device 1 is in a folded state, the inner side of the bending area 112 is the side facing the rotation axis 13 , and the inner side of the plane area 111 is the side fixedly connected to the first shell 121 and the second shell 122 .

[0064] The foldable electronic device 1 further includes a connector 14, which is located between the housing 12 and the plane area 111 of the screen 11, and is used to connect the housing 12 and the plane area 111 of the screen 11. The connector 14 has a first connection end and a second connection end along the thickness direction Y of the screen 11, the first connection end is connected to the plane area 111, and the second connection end is connected to the housing 12. As described above, during the bending process of the bending area 112 of the screen 11, the length of the inner side thereof decreases, thereby applying a pulling force (such as pulling force) along the width direction X of the screen 11 toward the bending area 112 to the inner side of the plane area 111 connected to the inner side of the bending area 112. Figure 4 The tension acts on the first connection end of the connector 14 connected to the plane area 111, so that the first connection end is subjected to a tension force along the width direction X of the screen 11 toward the bending area 112. The connector 14 is configured such that when the connector 14 is subjected to an external force along the width direction X of the screen 11, the first connection end can move along the width direction X of the screen 11 toward the bending area 112, or the first connection end has a tendency to move along the width direction X of the screen 11 toward the bending area 112 under the action of the external force. Therefore, under the action of the tension of the bending area 112, the plane area 111 connected to the first connection end moves toward the bending area 112 or has a tendency to move toward the bending area 112, thereby releasing part of the tensile stress of the bending area 112, reducing the stress of the bending area 112 in the bending state, reducing the risk of the bending area 112 breaking, and extending the service life of the screen 11.

[0065] It should be noted that, since the length reduction (L2-L4) of the inner side of the bending zone 112 is small when the foldable electronic device 1 switches from the unfolded state to the folded state, the travel of the first connecting end of the connecting member 14 toward the bending zone 112 under the action of external force is also small.

[0066] In a specific embodiment, Figure 5 As shown, Figure 5 for Figure 4 FIG. 1 is a schematic diagram of a structure of a foldable electronic device 1 after elastic deformation of a connector 14. The connector 14 may be adhesive, so that the flat area 111 of the screen 11 and the housing 12 are bonded together through the connector 14. The connector 14 is elastically deformable. When an external force is applied to the first connecting end of the connector 14 along the width direction X of the screen 11 toward the bending area 112 (such as Figure 5 In the direction of the arrow X1 shown in FIG. 1 , the first connecting end can move relative to the second connecting end toward the bending area 112, so that the connecting member 14 is in a position as shown in FIG. Figure 5 The elastic deformation state shown, that is, the first connection end connected to the plane area 111 is closer to the bending area 112 than the second connection end connected to the shell 12, so that the stress of the bending area 112 in the bending state is released through the elastic deformation of the connecting member 14, thereby reducing the risk of the bending area 112 breaking in the bending state.

[0067] Since the screen 11 is made of organic polymer material, the molecular chains of the polymer organic material will be broken in a low temperature environment, thereby increasing the hardness of the screen 11. That is, the hardness of the screen 11 in a low temperature environment is greater than its hardness at room temperature. When the foldable electronic device 1 is used in a low temperature environment and the screen 11 is in a bent state, the tensile stress generated in the bending area 112 will increase compared to when it is used in a room temperature environment, thereby increasing the tensile force of the bending area 112 on the plane area 111 along the width direction X of the screen 11. The bending area 112 of the screen 11 has a higher risk of breaking under the action of internal stress, resulting in a shorter service life of the screen 11.

[0068] In order to solve this technical problem, in the embodiment of the present application, the connector 14 is made of a material whose elastic modulus changes less when the temperature changes. That is, when the foldable electronic device 1 is used in a low-temperature environment, the reduction in the elastic modulus of the connector 14 caused by the temperature is small, so that the elastic deformation of the connector 14 in the low-temperature environment is still large, and the connector 14 is also prone to elastic deformation in the low-temperature environment, that is, the elastic deformation of the connector 14 at low temperatures is smaller than the reduction in the elastic deformation at room temperature, so that the connector 14 can still move toward the bending area 112 under the drive of the plane area 111 in the low-temperature environment to release part of the tensile stress of the bending area 112, thereby reducing the tensile stress generated by the bending area 112, reducing the risk of breaking the bending area 112, and extending the service life of the screen 11 in a low-temperature environment.

[0069] In this embodiment, by providing a connector 14 whose elastic modulus changes less between normal temperature and low temperature environment, when the foldable electronic device 1 is used in a low temperature environment, the connector 14 has a larger elastic deformation when subjected to a tensile force along the width direction X of the screen 11, so that the first connecting end can still move toward the bending area 112 driven by the plane area 111, thereby releasing part of the tensile stress of the bending area 112, reducing the risk of breakage of the bending area 112, and extending the service life of the screen 11 in a low temperature environment.

[0070] In a specific embodiment, the connector 14 may be made of organic silicone, which has excellent adhesion, corrosion resistance and insulation properties, can meet the use requirements of the screen 11, and improve the connection reliability between the screen 11 and the shell 12.

[0071] The connector 14 can specifically be a silicone sealant, which has good high and low temperature resistance and a temperature resistance range of -45°C to 350°C, so that the reduction in the elastic modulus of the connector 14 in a low temperature environment is small, that is, the elastic modulus of the connector 14 in a low temperature environment is closer to the elastic modulus in a normal temperature environment. In a low temperature environment, the first connecting end of the connector 14 can still move toward the bending zone 112 driven by the plane zone 111 to release part of the tensile stress in the bending zone 112.

[0072] In a specific embodiment, Figure 5As shown, the plane area 111 may include a first plane area 111a and a second plane area 111b located on both sides of the rotating shaft 13, and the first plane area 111a may be connected to the first shell 121 through the above-mentioned connecting member 14, and / or the second plane area 111b may be connected to the second shell 122 through the above-mentioned connecting member 14. That is, in the first specific embodiment, the first plane area 111a is connected to the first shell 121 through the above-mentioned connecting member 14; in the second specific embodiment, the second plane area 111b is connected to the second shell 122 through the above-mentioned connecting member 14; in the third specific embodiment, the first plane area 111a is connected to the first shell 121 through the above-mentioned connecting member 14, and the second plane area 111b is connected to the second shell 122 through the above-mentioned connecting member 14.

[0073] In the third embodiment, the connector 14 may include a first connector 141 and a second connector 142 , wherein the first plane area 111 a is connected to the first shell 121 via the first connector 141 , and the second plane area 111 b is connected to the second shell 122 via the second connector 142 .

[0074] In this embodiment, when the screen 11 is in a folded state, the foldable electronic device 1 is composed of the first plane area 111a, the first connecting member 141, the first shell 121, the second shell 122, the second connecting member 142, and the second plane area 111b from top to bottom along the thickness direction Y of the screen 11. The first connecting member 141 connecting the first plane area 111a and the first shell 121, and the second connecting member 142 connecting the second plane area 111b and the second shell 122 are elastically deformed, thereby driving the first plane area 111a and the second plane area 111b to move toward the bending area 112, reducing the stress of the bending area 112 from both sides of the bending area 112, and further reducing the risk of the bending area 112 breaking in the folded state.

[0075] In such Figure 5In the illustrated embodiment, the first plane area 111a of the foldable electronic device 1 can be connected to the first housing 121 via a first connector 141, and the second plane area 111b can be connected to the second housing 122 via a second connector 142, and the ratio of the area S1 of the first connector 141 to the area S2 of the first plane area 111a satisfies: 0.4≤S1 / S2≤0.8, so that the first connector 141 has a high connection reliability between the first plane area 111a and the first housing 121, and the ratio of the area S3 of the second connector 142 to the area S2 of the second plane area 111b satisfies: 0.4≤S3 / S4≤0.8, so that the second connector 142 has a high connection reliability between the second plane area 111b and the second housing 122. In this embodiment, the ratio of the area of ​​the first connector 141 to the first plane area 111a and the ratio of the area of ​​the second connector 142 to the second plane area 111b can be the same or different.

[0076] For example, S1 / S2 can be 0.4, 0.5, 0.6, 0.7, 0.8, etc., and S3 / S4 can be 0.4, 0.5, 0.6, 0.7, 0.8, etc.

[0077] In a specific embodiment, Figure 5 As shown, along the width direction X of the screen 11 , there is a gap between the first connecting member 141 and the rotating shaft 13 , and there is a gap between the second connecting member 142 and the rotating shaft 13 , and the gap provides space for the first connecting member 141 and the second connecting member 142 to undergo elastic deformation.

[0078] In a specific embodiment, Figure 5 As shown, the minimum gap W2 between the connector 14 and the rotating shaft 13 satisfies 3mm≤W2≤5mm. For example, W2 can be 3mm, 4mm, 5mm, etc. W2 should not be too large or too small. When W2 is too large, the distance between the connector 14 and the rotating shaft 13 is too large, which reduces the connection reliability between the end position of the plane area 111 toward the bending area 112 and the housing 12. When W2 is too small, the distance between the connector 14 and the rotating shaft 13 is too small, and when the connector 14 moves toward the bending area 112 driven by the plane area 111, it is easy to interfere with the rotating shaft 13. In this embodiment, when 3mm≤W2≤5mm, while ensuring the connection reliability between the end position of the plane area 111 toward the bending area 112 and the housing 12, it can provide space for the connector 14 to move toward the bending area 112 driven by the plane area 111, so as to release the stress of the bending area 112 and reduce the risk of fracture of the bending area 112.

[0079] In another specific embodiment, Figure 6 As shown, Figure 6This is a schematic diagram of the structure of the foldable electronic device 1 provided in the present application in another specific embodiment. The first housing 121 and the first plane area 111a can be connected by at least two first connectors 141, and the at least two first connectors 141 are spaced apart along the width direction X of the screen 11; the second housing 122 and the second plane area 111b can be connected by at least two second connectors 142, and the at least two second connectors 142 are spaced apart along the width direction X of the screen 11. In this embodiment, it is not necessary to cover the entire first plane area 111a, so that the amount of connectors 14 can be reduced, the structure of the foldable electronic device 1 can be simplified, and the cost can be reduced. It can also reduce the weight of the screen 11 and improve the portability of the foldable electronic device 1.

[0080] like Figure 7 In the embodiment shown, Figure 7 for Figure 6 Schematic diagram of the structure of the foldable electronic device 1 after the connector is elastically deformed. When the foldable electronic device 1 is in a folded state, the two first connectors 141 can be elastically deformed, and the first connecting ends of the two first connectors 141 can move toward the bending area 112 along the width direction X of the screen 11, and drive the first plane area 111a to move toward the bending area 112, thereby releasing part of the tensile stress in the bending area 112. Similarly, when the foldable electronic device 1 is in a folded state, the two second connectors 142 can be elastically deformed, and the first connecting ends of the two second connectors 142 can move toward the bending area 112 along the width direction X of the screen 11, and drive the second plane area 111b to move toward the bending area 112, thereby releasing part of the tensile stress in the bending area 112.

[0081] In other embodiments, the connecting members 14 may also be multiple and spaced apart along the width direction X of the screen 11 . The present application does not limit the specific number of the connecting members 14 .

[0082] like Figure 7 In actual use, the foldable electronic device 1 is often folded and the edge of the screen 11 is often rubbed, which makes the edge of the screen 11 more likely to be lifted up under the action of external force. Figure 7 As shown, at least the outer end 113 of the plane area 111 along the width direction X of the screen 11 is provided with a connecting member 14, which can further improve the connection reliability between the outer end 113 of the plane area 111 along the width direction X of the screen 11 and the shell 12, and reduce the risk of the outer end 113 of the plane area 111 along the width direction X of the screen 11 to warp.

[0083] In a specific embodiment, Figure 7As shown, the minimum distance W1 between the connecting member 14 and the outer end 113 of the plane area 111 satisfies W1≤5mm, so that at least one connecting member 14 is close to the outer end 113 of the plane area 111, thereby improving the connection reliability between the outer end 113 of the plane area 111 and the shell 12, avoiding the outer end 113 from warping under the action of external force during use, and extending the service life.

[0084] For example, the minimum distance between the connecting member 14 and the outer end 113 of the plane area 111 may be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0085] In another specific embodiment, Figure 8 As shown, Figure 8 This is a schematic diagram of the structure of the foldable electronic device 1 provided in the present application in another specific embodiment, wherein the connecting member 14 may also be a magnet. The screen 11 and the housing 12 of the foldable electronic device 1 can both be attracted by the magnet, so that the screen 11 and the housing 12 are magnetically connected through the connecting member located therebetween. When the foldable electronic device 1 is in the unfolded state, the magnetic attraction of the connecting member 14 on the screen 11 and the housing 12 is along the thickness direction Y of the screen 11. When the foldable electronic device 1 is used in a low-temperature environment and is in a bent state, the tensile stress in the bending zone 112 caused by the low temperature increases, so that the inner side of the plane area 111 is subjected to a tensile force in the width direction X of the screen 11 by the inner side of the bending zone 112, which also increases accordingly. The magnetism of the magnet is little affected by the low temperature, that is, in a low-temperature environment, the magnetic forces of the connector 14 on the plane area 111 and the shell 12 are close. Under the action of the larger tensile force of the bending zone 112 on the plane area 111, the inner side of the plane area 111 can overcome the magnetic attraction between it and the connector 14 and move toward the direction of the bending zone 112. At this time, the plane area 111 moves toward the bending zone 112 relative to the connector 14; or, under the action of the tensile force, the magnetic attraction between the outer side of the plane area 111 and the shell 12 can be overcome to make the plane area 111 move toward the bending zone 112. At this time, the plane area 111 drives the connector 14 to move toward the bending zone 112 relative to the shell 12 (such as Figure 8 As shown), the tensile stress of the bending zone 112 is reduced, thereby reducing the risk of the bending zone 112 breaking in a low temperature environment.

[0086] like Figure 8 As shown, the connector 14 shown by the solid line is a schematic diagram of the connector 14 when the foldable electronic device 1 is used in a low temperature environment and is in a bent state, and the connector 14 shown by the dotted line is a schematic diagram of the connector 14 when the foldable electronic device 1 is used in a normal temperature environment and is in a bent state.

[0087] Figure 8In the illustrated embodiment, the first plane area 111a and the first shell 121 may be connected via the above-mentioned connecting member 14, and / or the second plane area 111b and the second shell 122 may be connected via the above-mentioned connecting member 14. That is, in the first specific embodiment, the first plane area 111a and the first shell 121 are connected via the above-mentioned connecting member 14; in the second specific embodiment, the second plane area 111b and the second shell 122 are connected via the above-mentioned connecting member 14; in the third specific embodiment, the first plane area 111a and the first shell 121 are connected via the above-mentioned connecting member 14, and the second plane area 111b and the second shell 122 are connected via the above-mentioned connecting member 14.

[0088] In the third embodiment, when the connector 14 is a magnet, a plurality of first connectors 141 may be disposed between the first plane area 111a and the first shell 121 , and a plurality of second connectors 142 may be disposed between the second plane area 111b and the second shell 122 .

[0089] In another specific embodiment, when a magnet is used as a connector, and a connector is provided between the first plane area and the first shell, and a connector is provided between the second plane area and the second shell (not shown in the figure), at this time, the ratio of the area S1 of the first connector to the area S2 of the first plane area satisfies: 0.4≤S1 / S2≤0.8, so that the first connector has a high reliability of connecting the first plane area and the first shell, and the ratio of the area S3 of the second connector to the area S2 of the second plane area satisfies: 0.4≤S3 / S4≤0.8, so that the second connector has a high reliability of connecting the second plane area and the second shell. There is a gap between the first connector and the rotating shaft, and there is a gap between the second connector and the rotating shaft, and the gap provides space for the first connector and the second connector to move toward the bending area along the width direction of the screen.

[0090] In a specific embodiment, when a magnet is used as the connecting member 14, when the foldable electronic device 1 is used in a normal temperature environment and the screen 11 is in a folded state, the length of the bending zone 112 is H1, and when the foldable electronic device 1 is used in a low temperature environment and the screen 11 is in a folded state, the length of the bending zone 112 is H2. In this embodiment, when the foldable electronic device 1 is used in a low temperature environment and the screen 11 is in a folded state, the plane area 111 can drive the connecting member 14 to move toward the bending zone 112 to release part of the tensile stress of the bending zone 112.

[0091] Please also refer to Fig. 9 , Fig. 9 for Figure 8A partial enlarged view of part I in the figure. In this embodiment, under the tensile force of the bending zone 112, the plane area 111 drives the connecting member to move along the width direction X of the screen 11 toward the bending zone, and the distance H3 of the plane area 111 moving along the width direction X of the screen 11 is the same as the distance of the connecting member 14 moving along the width direction X. When the foldable electronic device 1 is used in a low temperature environment and is in a bent state, the length H2 of the bending zone 112 is equal to the sum of the length H1 of the bending zone 112 in the bent state at normal temperature and the distances moved by the first plane area 111a and the second plane area 111b, that is, H2 = H1 + 2H3.

[0092] In a specific embodiment, the ratio of H2 / H1 satisfies 1<H2 / H1≤1.05.

[0093] In this embodiment, the ratio of H2 / H1 can be 1.01, 1.02, 1.03, 1.04, 1.05, etc. The ratio of H2 / H1 should not be too large or too small. When it is too large, that is, the distance that the plane area 111 moves toward the bending area 112 is too long, which easily causes wrinkles on the screen 11 and damages the screen 11. When it is too small, that is, the distance that the plane area 111 moves toward the bending area 112 is too short, the tensile stress generated in the bending area 112 is not released enough, which easily causes the bending area 112 to break when used in a low temperature environment.

[0094] Therefore, in an embodiment of the present application, a connector 14 is provided between the flat area 111 of the screen 11 and the shell 12, and the connector 14 is a structure that enables the flat area 111 to move toward the bending area 112 in a low temperature environment, thereby increasing the length of the bending area 112 of the foldable electronic device 1 when it is in the bending process, thereby reducing the tensile stress of the bending area 112 and reducing the risk of the bending area 112 breaking in a low temperature environment.

[0095] In a specific embodiment, Fig.10 As shown, Fig.10 for Figure 6 A top view of a plane area 111 and a connecting member is shown, wherein the connecting member includes at least two first connecting segments 143 and at least two second connecting segments 144, the first connecting segments 143 extend along the length direction Z of the foldable electronic device, and the second connecting segments 144 extend along the width direction X of the foldable electronic device.

[0096] In this embodiment, the connector 14 includes at least two first connecting sections 143 and two second connecting sections 144, that is, the plane area 111 and the shell are connected by the first connecting section 143 extending along the length direction Z of the foldable electronic device, and are also connected by the second connecting section 144 extending along the width direction X of the foldable electronic device, which can improve the connection reliability between the plane area 111 and the shell and avoid cracking during use. The first connecting section 143 extends along the length direction Z of the foldable electronic device, and the second connecting section 144 extends along the width direction X of the foldable electronic device, so that a part of the connector is located between the plane area 111 and the shell, and there are parts of the connector along the length direction Z and the width direction X, so that the plane area 111 remains flat.

[0097] In a specific embodiment, Fig.10 As shown, the first connecting section 143 and the second connecting section 144 can form a rectangular structure, so that the plane area 111 and the shell can be in contact with the connecting piece at all circumferential positions, which can improve the connection reliability between the plane area 111 and the shell. At the same time, it can improve the sealing between the plane area 111 and the shell, reduce dust and other impurities from entering the accommodation space between the shell and the plane area 111, and reduce the risk of screen damage.

[0098] In this embodiment, Fig.11 As shown, a plane area 111 and the shell can be connected by at least two of the above-mentioned connecting members. Specifically, at least two rectangular structures surrounded by a first connecting section 143 and a second connecting section 144 can be provided between a plane area 111 and the shell, so as to further improve the connection reliability and stability between the plane area 111 and the shell.

[0099] In other embodiments, a plurality of rectangular structures surrounded by the first connecting segment and the second connecting segment may be provided on the plane area to improve the connection reliability between the plane area and the shell. The present application does not limit the specific number.

[0100] In a specific embodiment, Fig.11 As shown, Fig.11 This is a schematic structural diagram of the foldable electronic device 1 provided in the present application in another specific embodiment. A support plate 15 may also be provided on the housing 12 .

[0101] In this embodiment, a support plate 15 may be provided on the housing 12. The support plate 15 is located between the housing 12 and the plane area 111 along the thickness direction Y of the foldable electronic device 1. The support plate 15 and the plane area 111 are connected by a connector 14, that is, the connector 14 is connected to the housing 12 through the support plate 15. By providing a support plate 15 with a relatively flat surface on the housing 12 for connection with the plane area 111, the connection reliability between the plane area 111 and the support plate 15 can be improved, thereby improving the connection reliability between the screen 11 and the housing 12.

[0102] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
