Description

Technical Field

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

[0002] The narrow bezel design of display devices can highlight the display area itself, thereby providing consumers with a wider field of view and making the product look more refined and high-end. In addition, the extremely narrow bezel design can reduce product weight, improve portability, demonstrate product design and innovation capabilities, and meet the user's aesthetic and pursuit. Currently, the bezels (i.e., non-display area) of notebook products on the market are relatively wide due to factors such as cables and hinges, which affects the user experience. Utility Model Content

[0003] The present application provides an electronic device with a narrow frame.

[0004] In a first aspect, an embodiment of the present application provides an electronic device. The electronic device includes a display device, an input device and a folding mechanism, the folding mechanism is connected to the display device and the input device, and the display device and the input device are relatively unfolded or folded through the folding mechanism. The folding mechanism includes a first frame, the first frame includes a fixed portion and a rotating portion, and the rotating portion is fixedly connected to the fixed portion. The display device includes a display screen and a first shell, the display screen is mounted on the first shell, the fixed portion of the first frame is fixedly connected between the first shell and the display screen, and is arranged opposite to the display area of ​​the display screen, and the rotating portion of the first frame is rotatably connected to the input device. The electronic device also includes a flexible member, the flexible member is fixed between the fixed portion of the first frame and the first shell, and the hardness of the flexible member is less than the hardness of the first shell.

[0005] It can be understood that the fixing portion of the first support is fixedly connected between the first housing and the display screen, and is arranged opposite to the display area (Active Area, AA) of the display screen, that is, the fixed position of the fixing portion overlaps with the display area, and the fixing portion can be arranged on the back of the display area. The back of the display area refers to the side of the display screen that is opposite to the display surface.

[0006] Compared with the solution in which the fixing part of the first support is fixed to the non-display area of ​​the display screen, the present application fixes the fixing part of the first support to the back of the display area of ​​the display screen, which does not need to occupy the area of ​​the non-display area, can reduce the area of ​​the non-display area of ​​the display screen, and the "black border" of the display device is narrower. At the same time, the non-display area originally used to set the fixing part can also be used for display, further increasing the display area of ​​the electronic device, which is conducive to improving the screen-to-body ratio of the electronic device. The screen-to-body ratio can be the ratio of the area of ​​the display area of ​​the display device (that is, the display area of ​​the display screen) to the area of ​​the non-display area of ​​the display device.

[0007] Since the fixing part is arranged between the first shell of the display area, the thickness of the first shell will be set smaller to accommodate the fixing part without affecting the overall thickness of the display device. At this time, a flexible part with a hardness lower than that of the first shell is arranged between the fixing part and the first shell. This can reduce the risk of marks on the appearance surface of the shell caused by hard contact between two objects with greater hardness between the first shell and the fixing part.

[0008] In some possible implementations, the first housing includes a middle plate and a frame, the frame is connected to the periphery of the middle plate, the display screen is fixedly connected to an end of the frame away from the middle plate, and is arranged opposite to the middle plate. The thickness of the frame is greater than the thickness of the middle plate, and the fixing portion of the first support frame is fixedly connected to the middle plate.

[0009] It is understandable that when the display screen can be fixedly connected to the end of the frame away from the middle plate, the display screen can enclose a first accommodation space with the frame and the middle plate. The first accommodation space can be used to place electronic devices. The fixed portion of the first support frame is fixedly connected to the middle plate, and the fixed portion of the first support frame can be at least partially at the same height as the frame of the first shell in the Z direction, without increasing the thickness of the first shell. In addition, the frame can cover the first support frame, and the appearance of the electronic device is better.

[0010] In some possible implementations, the middle plate includes a thick portion and a thin portion, the thickness of the thick portion is greater than the thickness of the thin portion, and the fixing portion of the first support frame is fixedly connected to the thin portion.

[0011] It can be understood that the thickness of the thin part of the middle plate is smaller than the thickness of the thickness. The fixing part is fixedly connected to the thin part of the middle plate, and the thickness of the fixing part superimposed on the thin part can be within a smaller range.

[0012] In some possible implementations, the thickness of the thin portion is less than or equal to 1 mm.

[0013] It can be understood that the thickness of the thin portion is less than or equal to 1 mm, which is beneficial for the electronic device to have a smaller thickness.

[0014] In some possible implementations, it is characterized in that the hardness of the flexible member is smaller than the hardness of the fixing portion of the first support.

[0015] It is understandable that the flexible member can act as a buffer between the fixing portion and the first housing to avoid hard contact between the fixing portion and the first housing, which is beneficial to reducing deformation and stress at the connection between the fixing portion and the first housing during the opening and closing process of the electronic device.

[0016] In some possible implementations, the flexible member is adhesive-backed.

[0017] It can be understood that during the assembly process of the first support frame being fixed to the first shell, the adhesive backing can be first fixed to the fixing part of the first support frame or the first shell, and then the fixing part of the first support frame and the first shell are assembled. The adhesive backing can play a role of pre-fixing, which is beneficial to improve the assembly accuracy of the first support frame and the first shell.

[0018] In some possible implementations, the frame includes a lower frame, and when the electronic device is in an open state, the lower frame is connected to an end of the middle plate close to the input device, and the display screen is fixedly connected to an end of the lower frame away from the middle plate. The lower frame and the middle plate are an integrated structure.

[0019] It can be understood that the lower frame and the middle plate are an integrated structural member, and the connection reliability between the middle plate and the lower frame is better. Compared with the solution in which the lower frame and the middle plate are prepared separately and then the lower frame and the middle plate are fixed by means of easy-pull adhesive gluing, in this embodiment, the lower frame and the middle plate are set as an integrated structural member. When the connection area of ​​the lower frame and the middle plate is the same, the connection strength of the lower frame and the middle plate of this embodiment is better. In other words, when the connection strength of the lower frame and the middle plate is the same, the connection area of ​​the lower side and the middle plate in this embodiment can be set smaller. When the lower frame is connected between the cover plate and the middle plate, the length of the lower frame can remain unchanged, and the width can be set narrower. The cover plate can use more area to set the display panel, thereby reducing the bottom width of the "black frame" of the electronic device and increasing the screen-to-body ratio of the electronic device.

[0020] In some possible implementations, the lower frame includes a plate portion and a convex portion, the convex portion is connected to the inner side of the plate portion, the convex portion is connected between the middle plate and the display screen, and the plate portion is connected between the middle plate and the display screen.

[0021] It is understandable that the convex portion can be formed by part of the inner side surface of the lower frame protruding toward the first accommodation space. When the internal components of the display device are arranged, the position of the convex portion can avoid the internal components of the display device (such as electrical connection components). By forming the convex portion, the top and bottom areas of the lower frame can be increased without affecting the layout of the components in the first accommodation space. The connection area between the lower frame and the cover plate and the middle plate can be larger, and the connection reliability is better.

[0022] In some possible implementations, the fixing portion of the first support includes a first connection area and a second connection area, the first connection area is connected to the second connection area, the flexible member is fixedly connected to the first connection area, and the second connection area is fixedly connected to the first shell by gluing or welding.

[0023] It can be understood that the second connection area is fixedly connected to the first shell by gluing or welding, and the molding method is simple and easy to operate.

[0024] In some possible implementations, the first connection area surrounds the second connection area, and the second connection area is fixedly connected to the first shell by gluing.

[0025] It is understandable that, during the process of the second connection area being fixedly connected to the first shell by gluing,

[0026] In some possible implementations, the fixing portion of the first support further includes a third connection area, and the third connection area is fixedly connected to the first shell by screws.

[0027] It can be understood that, compared with the solution of using only one connection method, the connection between the fixing part and the first shell is fixedly connected by multiple fixed connection methods, and the connection reliability between the fixing part and the first shell is higher. In addition, compared with the solution of fixing the first support frame and the first shell only with screws, the present embodiment uses both gluing / welding and screw locking to fix, which can reduce the length L of the screw and reduce the thickness of the first shell at the connection.

[0028] In some possible implementations, there are multiple screws, and the multiple screws are arranged in an asymmetrical manner.

[0029] It can be understood that, compared with the solution of using only one connection method, the fixed connection between the fixed part and the first shell is achieved through multiple fixed connection methods, the tightening force required by the screws is reduced, there is no symmetry requirement for the fixing position of the screws, and the arrangement of the screws can be an asymmetric arrangement, also known as a discrete arrangement, which makes it easier to avoid the internal components of the display device (such as drive components, electrical connection components) when tightening the screws.

[0030] In some possible implementations, the length L of the screw is in the range of 1.2 mm to 1.5 mm. In this way, the screw is shorter and will not interfere with the arrangement of components in the display device.

[0031] In some possible implementations, the rotating portion of the first support frame includes a first connecting section, and the first connecting section is fixedly connected to one side of the fixed portion of the first support frame. The first connecting section is in an arc shape, and a projection of the first connecting section along a first direction on the first shell overlaps at least partially with the first shell, the first direction is a thickness direction of the display screen, and an angle between an extension direction of the first connecting section and the first direction is less than or equal to degrees.

[0032] It can be understood that the transition section from the rotating part to the fixed part (that is, the first connecting section) is roughly parallel to the thickness direction of the display screen, so that the part of the first support frame fixed under the display panel is as parallel to the first shell as possible, and the length of the first support frame in the first accommodating space and the inclined setting of the display panel is minimized as much as possible, which is beneficial to reducing the bottom edge width of the "black frame" of the electronic device and improving the screen-to-body ratio of the electronic device.

[0033] In some possible embodiments, the folding mechanism also includes a second frame and an axis core, the second frame is fixedly connected to the input device, a part of the axis core is fixedly connected to the rotating part of the first frame, and the other part is rotatably connected to the second frame, and the first frame is rotatably connected to the second frame via the axis core.

[0034] It can be understood that when the first support frame is fixed to the first shell, the display device can be opened or closed relative to the input device through the first support frame, the shaft core, and the second support frame.

[0035] In some possible implementations, the folding mechanism further includes a shaft cover, which is fixedly connected to the rotating portion of the first support frame and forms a threading channel with the rotating portion. The electronic device further includes a flexible circuit board, a portion of which is located in the display device and electrically connected to the display device, and the other end of which passes through the threading channel into the input device and is electrically connected to the input device.

[0036] It can be understood that compared with the solution of using a cable to pass through the folding mechanism, the thickness of the flexible circuit board is smaller than the cable, and the bending radius of the flexible circuit board when entering the threading channel of the folding mechanism can be smaller. The cover plate can use more area to set the display panel, thereby reducing the border width of the electronic device and increasing the screen-to-body ratio of the electronic device.

[0037] In some possible implementations, a portion of the flexible circuit board is fixedly connected to the rotating part, so that the risk of shaking of the flexible circuit board can be reduced and the reliability of the electrical connection is better.

[0038] In some possible implementations, the first support frame further includes a first positioning structure and a second positioning structure, the first positioning structure and the second positioning structure are fixed in the threading channel at intervals along a second direction, and the second direction is a width direction of the threading channel;

[0039] The flexible circuit board is partially located between the first positioning structure and the second positioning structure, and the relationship between the distance K between the first positioning structure and the second positioning structure along the second direction and the width N of the flexible circuit board satisfies:

[0040] 1≤K / N≤1.02.

[0041] It can be understood that arranging the first positioning structure and the second positioning structure along the second direction at a distance substantially equal to the width N of the flexible circuit board is beneficial to positioning the flexible circuit board on the folding mechanism.

[0042] In some possible implementations, the relationship between the width M of the threading channel and the width N of the flexible circuit board satisfies:

[0043] 1.05≤M / N≤1.15.

[0044] It can be understood that a larger gap is reserved between the threading channel and the flexible circuit board. When the flexible circuit board passes through the threading channel, the routing direction of the flexible circuit board can be set at an angle to the length direction of the threading channel. The gap can be used to accommodate the redundancy of the flexible circuit board in the width direction, thereby reducing the risk of the flexible circuit board in the first accommodating space arching and squeezing the electrical connection components.

[0045] In some possible implementations, the display device further includes a drive assembly, the drive assembly is electrically connected to the display screen, the drive assembly is installed between the display screen and the first housing, and is arranged opposite to the display area (AA) of the display screen, and the drive assembly and the first support frame are arranged at a distance. The display device further includes an electrical connection assembly, one end of the electrical connection assembly is electrically connected to the display screen, and the other end is electrically connected to the drive assembly, and when the electronic device is turned on, the electrical connection assembly is located on a side of the drive assembly close to the input device.

[0046] The display device also includes a stopper, and the stopper and the electrical connection assembly are fixed on the same side of the display screen. A portion of the flexible circuit board is located between the stopper and the first housing, and the distance between the stopper and the first housing is smaller than the distance between the electrical connection assembly and the first housing.

[0047] It is understandable that the limiting member can be used to prevent the flexible circuit board from arching too much and squeezing the electrical connection components during the opening and closing process of the electronic device.

[0048] In some possible embodiments, the limit member includes a main body and an extension portion, the main body is fixed to the display screen, one end of the extension portion is connected to an end of the main body away from the display screen, the extension portion and the main body are arranged at an angle, and the electrical connection component is located on a side of the extension portion away from the flexible circuit board.

[0049] It can be understood that at least part of the electrical connection component is placed on the side of the extension portion away from the first shell, and the extension portion can be located between the flexible circuit board and the electrical connection component. During the opening and closing process of the electronic device, the limit member can protect the electrical connection component and further reduce the risk of squeezing the electrical connection component due to excessive arching of the flexible circuit board.

[0050] In some possible implementations, the display device further includes a driving assembly, which is electrically connected to the display screen, installed between the display screen and the first shell, and arranged opposite to the display area (AA) of the display screen, and the driving assembly and the first support frame are spaced apart.

[0051] It can be understood that compared with the solution in which the driving component is fixed to the non-display area of ​​the display screen, the driving component in this embodiment does not need to occupy the area of ​​the non-display area, and the display area can be larger, which is beneficial to reducing the bottom edge width of the "black frame" of the electronic device and improving the screen-to-body ratio of the electronic device.

[0073] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application. The embodiments described herein with reference to the drawings are exemplary and intended to be used to explain the present application, and should not be understood as limiting the present application.

[0074] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or an undetachable connection; it can be a direct connection or an indirect connection through an intermediate medium. It should be understood that in the present application, "electrical connection" can be understood as the physical contact and electrical conduction of components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as copper foil or wires on a printed circuit board (PCB) that can transmit electrical signals. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship. For example, A is connected to B or A is connected to B, which can mean that there is a fastening component (such as a screw, bolt, rivet, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0075] Furthermore, the word "fixed" in this article should also be understood in a broad sense. For example, "fixed" can be directly fixed or indirectly fixed through an intermediate medium. Among them, "fixed" means connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", etc., are only referenced to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" refers to two or more than two.

[0076] In the description of the embodiments of the present application, unless otherwise specified, “ / ” means or, for example, A / B can mean A or B; the “and / or” in the text is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, “multiple” refers to two or more than two.

[0077] In the embodiments of the present application, the terms "first", "second", "third", and "fourth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "third", and "fourth" may explicitly or implicitly include one or more of the features.

[0078] In addition, in the embodiments of the present application, the limitations of the relative position relationship mentioned, such as parallel, vertical, aligned, etc. These limitations are all for the current state of the art, rather than absolutely strict limitations, and a small amount of deviation is allowed, and it is possible to be approximately parallel, approximately vertical, approximately aligned, etc. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0079] Figure 1 It is a structural schematic diagram of an electronic device 1000 provided in an embodiment of the present application when it is in a closed state. Figure 2 yes Figure 1 The structure diagram of the electronic device 1000 shown is in an open state. Figure 3 yes Figure 1 FIG. 1 is a schematic diagram of an exploded view of an embodiment of an electronic device 1000 shown in FIG. Figures 1 to 3 Some components of the electronic device 1000 are shown schematically, and the actual size, actual position and actual structure of these components are not subject to the present invention. Figures 1 to 3 The following drawings only schematically show some components, and the actual size, actual position and actual structure of these components are not limited by the following drawings. The details will not be repeated below.

[0080] For ease of description, Figure 1 As shown, the length direction of the electronic device 1000 is defined as the X axis. The width direction of the electronic device 1000 is defined as the Y axis. The thickness direction of the electronic device 1000 is defined as the Z axis. In other implementations, the coordinate system can also be flexibly set according to other requirements.

[0081] like Figures 1 to 3 As shown, the electronic device 1000 may be a notebook computer or other foldable electronic devices 1000. The electronic device 1000 shown in the drawings is described by taking a notebook computer as an example.

[0082] Exemplarily, the electronic device 1000 may include a display device 100, an input device 200, a folding mechanism 300, and a signal transmission structure 400. The folding mechanism 300 may be connected between the display device 100 and the input device 200. The display device 100 and the input device 200 may be relatively unfolded or folded by the folding mechanism 300, so that the electronic device 1000 may be switched between an open state and a closed state. Figure 1 The electronic device 1000 is shown in a closed state. Figure 2 The electronic device 1000 is shown to be in an open state.

[0083] It is understandable that the electronic device 1000 includes multiple opening states, and different opening states can be indicated by the angle A between the display device 100 and the input device 200 .

[0084] Exemplarily, when the electronic device 1000 is in a closed state, the angle A may be 0°. It is understandable that due to manufacturing process or design, when the electronic device 1000 is in a closed state, the angle A may be greater than 0°, for example, the angle A may be 5°.

[0085] For example, when the electronic device 1000 is in a closed state, the display device 100 and the input device 200 may overlap each other in the Z direction. At this time, the XY plane size of the electronic device 1000 is small, which is convenient for users to carry and store.

[0086] Exemplarily, the signal transmission structure 400 may be used for electrical signal transmission between the input device 200 and the display device 100. This will be described in detail below with reference to the accompanying drawings.

[0087] Figure 4 yes Figure 3 Schematic diagram of an exploded view of an embodiment of a display device 100 is shown in FIG. Figure 5 yes Figure 3 FIG. 1 is a partial cross-sectional view of an embodiment of the display device 100 at a section line AA at another angle.

[0088] like Figure 4 and Figure 5 As shown, the display device 100 may include a display screen 10, a first housing 20, a drive assembly 30, and an electrical connection assembly 40. The display screen 10 may be fixed to the first housing 20, and together with the first housing 20, a first accommodation space 50 is enclosed. The drive assembly 30 and the electrical connection assembly 40 may be disposed in the first accommodation space 50.

[0089] Exemplarily, the display screen 10 may include a stacked display panel 1 and a cover plate 2. The display panel 1 may be used to display an image. Exemplarily, the display panel 1 may be used to display an image, etc. The display screen of the display panel 1 may be an organic light-emitting diode (OLED) display panel, or an active-matrix organic light-emitting diode (AMOLED) display panel, or a liquid crystal display panel (LCD), etc.

[0090] In some embodiments, the cover plate 2 may be fixed on the display surface of the display panel 1. The cover plate 2 may be used to protect the display panel 1.

[0091] In some embodiments, the cover plate 2 may be made of a transparent material, so that the cover plate 2 will not affect the display pattern of the display panel 1. For example, the cover plate 2 may be made of transparent glass or polyimide.

[0092] In some embodiments, the cover plate 2 can be fixed to the first housing 20, and together with the first housing 20, enclose a first accommodation space 50. The display panel 1 can be disposed in the first accommodation space 50. In this way, the cover plate 2 can be used to cooperate with the first housing 20 to protect the display panel 1.

[0093] In some embodiments, the cover plate 2 may include a display area 201 and a non-display area 202 (eg, Figure 4 As shown). The non-display area 202 is connected to the periphery of the display area 201. The portion of the display panel 1 for displaying an image is fixedly connected to the display area 201 of the cover plate. The non-display area 202 can be connected to the first housing 20. It is understood that the location of the display area 201 of the cover plate 2 is also the display area (AA) of the display screen 10. It is understood that

[0094] It is understandable that when the display device 100 displays an image, a circle of "black frame" will appear around the display area (AA) of the display screen 10. The "black frame" can be composed of the non-display area 202 of the cover plate, and a portion of the first shell 20 that cannot be displayed. It is understandable that the ratio of the area of ​​the display area 201 to the area of ​​the "black frame" can also be called the screen-to-body ratio. When the sum of the areas of the display area 201 and the "black frame" remains unchanged, the smaller the "black frame", the larger the display area, and the larger the screen-to-body ratio. Increasing the screen-to-body ratio of the electronic device 1000 is conducive to improving the user experience.

[0095] Exemplarily, the "black frame" (i.e., the non-display area 202) may include a bottom edge, and the width of the bottom edge is D (i.e., the length of the bottom edge in the Y-axis direction). When the electronic device 1000 is in the open state, the bottom edge is located on the side of the display area 201 close to the input device 200. It can be understood that the bottom side of the display device 100 is the side of the display device 100 close to the input device 200 when the electronic device 1000 is in the open state. The rotational connection between the display device 100 and the input device 200 and the transmission of electrical signals both need to pass through the bottom side of the display device 100, so the bottom edge of the "black frame" of the display device 100 has a larger width than other edges.

[0096] Figure 6 yes Figure 4 A schematic structural diagram of an embodiment of the first shell 20 is shown in FIG.

[0097] like Figure 5 and Figure 6 As shown, the first housing 20 may include a middle plate 21 and a frame 22. The frame 22 may be connected to the periphery of the middle plate 21. The display screen 10 may be fixedly connected to an end of the frame 22 away from the middle plate 21, and arranged opposite to the middle plate 21. Exemplarily, the cover plate 2 of the display screen 10 may be fixed to an end of the frame 22 away from the middle plate 21.

[0098] In some embodiments, the middle plate 21 and the frame 22 may both be made of metal materials, so that the first housing 20 has better strength.

[0099] In some embodiments, the thickness of the frame 22 may be greater than the thickness of the middle plate 21. In this way, when the display screen 10 can be fixedly connected to the end of the frame 22 away from the middle plate 21, the display screen 10 can enclose a first accommodation space 50 with the frame 22 and the middle plate 21. The first accommodation space 50 can be used to place electronic devices, such as the drive assembly 30 and the electrical connection assembly 40. Exemplarily, the cover plate 2 of the display screen 10 can enclose the first accommodation space 50 with the frame 22 and the middle plate 21, and the display panel 1 can be fixed to the side of the cover plate 2 facing the first accommodation space 50.

[0100] In some embodiments, the middle plate 21 may include a thick portion 211 and a thin portion 212. The thick portion 211 is connected to the thin portion 212. The thickness of the thick portion 211 is greater than the thickness of the thin portion 212. Exemplarily, the thick portion 211 may be located at the periphery of the middle plate 21. It is understood that a portion of the middle plate 21 is set thicker to form the thick portion 211. The thick portion 211 has a larger thickness, which can strengthen the structure of the middle plate 21 to increase the overall strength of the first shell 20.

[0101] Exemplarily, the thickness of the thin portion 212 is less than or equal to 1 millimeter (mm).

[0102] In some embodiments, the middle plate 21 may be substantially rectangular. The frame 22 may include an upper frame 221, a lower frame 222, a left frame 223, and a right frame 224. The upper frame 221, the lower frame 222, the left frame 223, and the right frame 224 may be fixed to the four sides of the middle plate 21, respectively. A portion of the display screen 10 is fixedly connected to an end of the upper frame 221 away from the middle plate 21, a portion of the display screen 10 is fixedly connected to an end of the lower frame 222 away from the middle plate 21, a portion of the display screen 10 is fixedly connected to an end of the left frame 223 away from the middle plate 21, and a portion of the display screen 10 is fixedly connected to an end of the right frame 224 away from the middle plate 21. It is understood that when the electronic device 1000 is in an open state, the lower frame 222 is connected to an end of the middle plate 21 close to the input device 200, and the upper frame 221 is connected to an end of the middle plate 21 away from the input device 200.

[0103] Exemplarily, the lower frame 222 may include a plurality of sub-boards 2221, and the plurality of sub-boards 2221 are connected to the middle board 21 at intervals. In this way, the gap 2222 between two adjacent sub-boards 2221 may be used for routing or installing the folding mechanism 300. It is understandable that by providing the lower frame 222, the components in the first accommodation space 50 may be shielded, which may be beneficial to the integrity of the outer surface of the electronic device 1000.

[0104] In some embodiments, the middle plate 21 and the lower frame 222 can be an integral structural member. The two components are integrated by an integral molding process to obtain an integrated structure, which means that in the process of forming one of the two components, the component is connected to the other component, and there is no need to connect the two components together by reprocessing (such as bonding, welding, snap connection, screw 370 connection). Exemplarily, the middle plate 21 and the lower frame 222 can be integrally formed by a metal processing process. In this way, the connection reliability between the middle plate 21 and the lower frame 222 is better.

[0105] It can be understood that, compared with the solution in which the lower frame 222 and the middle plate 21 are prepared separately and then fixed to the lower frame 222 and the middle plate 21 by means of easy-pull adhesive gluing, in this embodiment, the lower frame 222 and the middle plate 21 are set as an integral structural member. When the connection area of ​​the lower frame 222 and the middle plate 21 is the same, the connection strength of the lower frame 222 and the middle plate 21 in this embodiment is better. In other words, when the connection strength of the lower frame 222 and the middle plate 21 is the same, the connection area of ​​the lower side and the middle plate 21 in this embodiment can be set smaller. When the lower frame 222 is connected between the cover plate 2 and the middle plate 21, the length of the lower frame 222 can remain unchanged, and the width can be set narrower. The cover plate 2 can use more area to set the display panel 1, thereby reducing the bottom width of the "black frame" of the electronic device 1000 and improving the screen-to-body ratio of the electronic device 1000.

[0106] In some embodiments, the upper frame 221, the left frame 223 and the right frame 224 can be an integral structure with the middle plate 21. In other words, the middle plate 21 and the frame 22 are an integral structure. In some embodiments, the upper frame 221, the left frame 223 and the right frame 224 can be selectively provided or not provided.

[0107] like Figure 5 and Figure 6 As shown, the lower frame 222 includes an inner side surface 2223 , an outer side surface 2224 , a top surface 2225 and a bottom surface 2226 . Figure 5The dotted lines schematically distinguish the middle plate 21 and the lower frame 222. The inner side surface 2223 and the outer side surface 2224 are disposed opposite to each other, and the top surface 2225 and the bottom surface 2226 are disposed opposite to each other. The top surface 2225 is fixedly connected to the cover plate 2. The bottom surface 2226 is fixedly connected to the middle plate 21. The inner side surface 2223 faces the first accommodation space 50.

[0108] In some embodiments, the lower frame 222 may include a plate portion 2227 and a convex portion 2228 ( Figure 6 The dotted line schematically divides the plate portion 2227 and the convex portion 2228, and the convex portion 2228 is connected to the inner side of the plate portion 2227. The inner side of the plate portion 2227 faces the first accommodation space 50. The convex portion 2228 is connected between the middle plate 21 and the display screen 10, and the plate portion 2227 is connected between the middle plate 21 and the display screen 10. That is, the convex portion 2228 and the plate portion 2227 can be used to carry the display screen. It can be understood that the convex portion 2228 can be formed by a portion of the inner side surface 2223 of the lower frame 222 protruding toward the first accommodation space 50. When the internal components of the display device 100 are arranged, the position of the protrusion 2228 can avoid the internal components of the display device 100 (such as the electrical connection component 40). By forming the protrusion 2228, the area of ​​the top surface 2225 and the bottom surface 2226 of the lower frame 222 can be increased without affecting the layout of the components in the first accommodating space 50. The connection area between the lower frame 222 and the cover plate 2 and the middle plate 21 can be larger, and the connection reliability is better.

[0109] For example, the number of the convex portions 2228 may be multiple, and the multiple convex portions 2228 may be arranged at intervals along the extension direction of the plate portion 2227. In this way, the connection area between the lower frame 222 and the cover plate 2 and the middle plate 21 may be further increased. It is understandable that the convex portion 2228 may avoid the internal components (such as the electrical connection component 40) of the display device 100, and a part of the internal components may be located between two adjacent convex portions 2228.

[0110] For example, in the Y-axis direction, the minimum thickness W of the top surface 2225 may be less than or equal to 2 mm. For example, the minimum thickness W of the lower side surface may be 2 mm, 1.8 mm, 1.5 mm, 1.2 mm, or 1.0 mm.

[0111] In some embodiments, the cover plate 2 can be fixed to the first shell 20 by adhesive. A portion of the adhesive can be fixed between the top surface 2225 of the lower frame 222 of the first shell 20 and the cover plate 2. The adhesive can be changed according to the shape of the top surface 2225 of the lower frame 222. It is understood that when the top surface 2225 of the lower frame 222 is an irregular shape, the shape of the adhesive can also be an irregular shape. Exemplarily, in the Y-axis direction, the minimum thickness of the adhesive can be less than or equal to 2mm. For example, the minimum thickness of the adhesive can be 2mm, 1.8mm, 1.5mm, 1.2mm, 1.0mm.

[0112] In other embodiments, the first housing 20 may be in other shapes besides a rectangle, and the frame 22 may be in other shapes. When the electronic device 1000 is in an open state, the lower frame 222 is the portion of the frame 22 connected to the side of the middle plate 21 close to the input device 200 .

[0113] like Figure 5 and Figure 6 As shown, the driving assembly 30 can be installed in the first accommodating space 50. The driving assembly 30 can be spaced apart from the first support frame 310. The driving assembly 30 can be electrically connected to the display screen 10. The driving assembly 30 can be used to input a driving signal to the display screen 10. Exemplarily, the driving assembly 30 can be electrically connected to the display panel 1. The driving assembly 30 can be used to input a driving signal to the display panel 1 so that the display panel 1 displays an image. Exemplarily, the driving assembly 30 can include a circuit board 31 and a driver 32. The driver 32 is fixed to the circuit board 31.

[0114] In some embodiments, the drive assembly 30 can be installed between the display screen 10 and the first shell 20, and is arranged relative to the display area of ​​the display screen 10. That is, the drive assembly 30 can be stacked with the display panel 1 in the first direction. The first direction refers to the thickness direction of the display screen 10. Exemplarily, the drive assembly 30 can be fixed to the side of the display panel 1 away from the cover plate 2. It can be understood that compared with the solution in which the drive assembly 30 and the display panel 1 are fixed to the cover plate 2 at intervals, the drive assembly 30 and the display panel 1 are stacked in this embodiment. When the area of ​​the cover plate 2 remains unchanged, the drive assembly 30 does not need to occupy the area on the cover plate 2, and the area of ​​the display panel 1 can be larger, which is conducive to reducing the bottom width of the "black frame" of the electronic device 1000 and improving the screen-to-body ratio of the electronic device 1000.

[0115] In some embodiments, one end of the electrical connection component 40 may be electrically connected to the display panel 1, and the other end may be electrically connected to the driving component 30. The electrical connection component 40 may be used for transmitting electrical signals between the driving component 30 and the display panel 1. Exemplarily, one end of the electrical connection component 40 may be fixedly connected to the display panel 1 and electrically connected to the display panel 1, and the other end may be fixedly connected to the circuit board 31 of the driving component 30 and electrically connected to the circuit board 31.

[0116] Exemplarily, the electrical connection component 40 may be a chip-on-film (COF) or other flexible electrical transmission structure. In this way, part of the electrical connection component 40 may be bent, thereby facilitating the electrical connection between the stacked drive component 30 and the display panel 1. The electrical connection component 40 is not easy to fall off from the drive component 30 or the display panel 1, and the electrical connection reliability is better.

[0117] Figure 7 yes Figure 3 Schematic diagram of an implementation of an input device 200 shown in .

[0118] like Figure 7 As shown, the input device 200 may include an input module 210 and a second housing 220 .

[0119] In some embodiments, the input module 210 may be fixed to the second housing 220. For example, the input module 210 may include a touch panel 2101 and / or a plurality of buttons 2102. The input module 210 may be installed in the second housing 220.

[0120] In some embodiments, the electronic device 1000 may further include multiple components (not shown in the figure), and the multiple components may be installed in the first housing 20 or the second housing 220. Exemplarily, the multiple components may include but are not limited to a mainboard, a control circuit, an internal memory, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, and a sensor module.

[0121] Figure 8 yes Figure 3 A structural schematic diagram of an embodiment of a folding mechanism 300 is shown in FIG. Fig. 9 yes Figure 8 FIG. 2 is an exploded schematic diagram of an embodiment of a folding mechanism 300 shown in FIG.

[0122] like Figure 8 and Fig. 9As shown, the folding mechanism 300 may include a first support frame 310, a second support frame 320, a shaft core 330 and a rotating shaft cover 340. A portion of the shaft core 330 is fixedly connected to the first support frame 310, and another portion is rotatably connected to the second support frame 320. In this way, the first support frame 310 can be rotatably connected to the second support frame 320 through the shaft core 330.

[0123] Fig.10 yes Fig. 9 A schematic diagram of an embodiment of a first support frame 310 is shown in FIG.

[0124] like Figure 8 and Fig.10 As shown, the first support frame 310 may include a rotating portion 311 and a fixed portion 312, wherein the rotating portion 311 is fixedly connected to one end of the fixed portion 312. The rotating portion 311 may be used to be fixedly connected to the shaft core 330. For example, the rotating portion 311 may be fixedly connected to the middle portion of the shaft core 330.

[0125] In some embodiments, the rotating portion 311 is substantially semi-cylindrical in shape. The rotating portion 311 may have a first space 3112 .

[0126] In some embodiments, the rotating part 311 and the fixing part 312 may be integrally formed structural parts. In this way, the connection reliability between the rotating part 311 and the fixing part 312 is better, and the rotating part 311 is prevented from falling off from the fixing part 312 when the external force is large. In other embodiments, other connection relationships may also be used.

[0127] In some embodiments, the folding mechanism 300 may further include a fastener 350. One end of the fastener 350 may be fixedly connected to the rotating portion 311 of the first support frame 310, and the other end may be fixedly connected to the shaft core 330. It is understood that the fastener 350 is provided to achieve a fixed connection between the first support frame 310 and the shaft core 330. Exemplarily, the fastener 350 may be a screw or a bolt.

[0128] In some embodiments, the number of the fastener 350 may be one or more. Figure 8 and Fig. 9 Two fasteners 350 are shown in the figure, and the two fasteners 350 can be fixedly connected to the shaft core 330 along the length direction of the shaft core 330.

[0129] like Figure 8 and Fig. 9 As shown, the second support frame 320 may be provided with a rotation groove 321, and the shaft core 330 may be rotatably connected in the rotation groove 321. Exemplarily, there may be two second supports 320. Both ends of the shaft core 330 may be rotatably connected in the rotation grooves 321 of the two second supports 320, respectively.

[0130] Fig.11 yes Figure 8 FIG. 4 is a cross-sectional view of an embodiment of the folding mechanism 300 shown in FIG. 3 at another angle at the section line BB.

[0131] like Fig.11 As shown, the shaft cover 340 can be fixedly connected to the rotating part 311 of the first support frame 310, and the shaft cover 340 and the rotating part 311 can enclose a threading channel 360. The threading channel 360 can be used to accommodate the signal transmission structure 400. Exemplarily, the shaft cover 340 can be at least partially located on a side of the rotating part 311 facing away from the first space 3112, and is used to enclose the threading channel 360 with the rotating part 311.

[0132] In some embodiments, the hinge cover 340 may be at least partially located on a side of the rotating portion 311 facing away from the first space 3112. The hinge cover 340 may be used to expose the hinge cover 340 between the first housing 20 and the second housing 220 when the electronic device 1000 is in a pop-up state or an open state. The hinge cover 340 may be used to cover the portion of the first support frame 310 exposed between the first housing 20 and the second housing 220. In this way, the appearance of the electronic device 1000 is more beautiful.

[0133] Fig.12 yes Figure 3 FIG. 1 is a schematic diagram of a partial structural assembly of a folding mechanism 300 and a display device 100 according to an embodiment of the present invention. Fig.13 yes Fig.12 Schematic diagram of the structure of an embodiment of the structure shown in FIG.

[0134] like Fig.12 and Fig.13 As shown, the first support frame 310 of the folding mechanism 300 can be fixedly connected to the first shell 20. Exemplarily, the fixing portion 312 of the first support frame 310 can be fixedly connected to the first shell 20. Exemplarily, the fixing portion 312 can be fixedly connected to the first shell 20 by one or more of bonding, welding, snap connection, screw connection, etc.

[0135] In some embodiments, the fixed portion 312 of the first support frame 310 can be fixedly connected to the middle plate 21 of the first housing 20, and the rotating portion 311 of the first support frame 310 can be connected to the fixed portion 312 via the gap 2222. It can be understood that by fixing the fixed portion 312 of the first support frame 310 to the middle plate 21, the fixed portion 312 of the first support frame 310 can be at least partially at the same height as the frame 22 of the first housing 20 in the Z direction, and the thickness of the first housing 20 will not be increased. In addition, the frame 22 can shield the first support frame 310, and the appearance of the electronic device 1000 is better.

[0136] Exemplarily, the fixing portion 312 may be fixedly connected to the thin portion 212 of the middle plate 21. It is understood that the thickness of the thin portion 212 of the middle plate 21 is less than the thickness of the thick portion 211. The fixing portion 312 is fixedly connected to the thin portion 212 of the middle plate 21, and the thickness of the fixing portion 312 superimposed on the thin portion 212 may be within a smaller range, which is conducive to a smaller thickness of the display device 100.

[0137] Fig.14 yes Fig.13 FIG. 1 is a schematic diagram of an assembly of the flexible member 500 and the first support frame 310 at another angle according to an embodiment of the present invention.

[0138] like Fig.13 and Fig.14 As shown, the electronic device 1000 may further include a flexible member 500. The flexible member 500 may be fixed between the first housing 20 and the fixing portion 312 of the first support frame 310. The hardness of the flexible member 500 is less than the hardness of the first housing 20. It is understandable that the flexible member 500 may serve as a buffer between the first support frame 310 and the first housing 20. During the assembly process of the fixing portion 312 of the first support frame 310 and the first housing 20, the flexible member 500 may also be used to avoid excessive abutment between the fixing portion 312 and the first housing 20, resulting in appearance marks on the first housing 20.

[0139] In some embodiments, the hardness of the flexible member 500 is less than the hardness of the fixed portion 312 of the first support frame 310. Exemplarily, the material of the flexible member 500 can be rubber or foam. It is understandable that, in this way, the flexible member 500 can serve as a buffer between the fixed portion 312 and the first shell 20 to avoid hard contact between the fixed portion 312 and the first shell 20. During the opening and closing process of the electronic device 1000, it is beneficial to reduce the deformation and stress at the connection between the fixed portion 312 and the first shell 20.

[0140] In some embodiments, the flexible member 500 may also be adhesive. In this way, during the assembly process of the first support frame 310 being fixed to the first shell 20, the adhesive may be first fixed to the fixing portion 312 of the first support frame 310 or the first shell 20, and then the fixing portion 312 of the first support frame 310 and the first shell 20 are assembled, and the first support frame 310 is fixed to the first shell 20 by the connecting layer 600 and the screws 370. At this time, the adhesive may play a role of pre-fixation, which is conducive to improving the assembly accuracy of the first support frame 310 and the first shell 20.

[0141] like Fig.14As shown, the fixing portion 312 may include a first connection area 3121 (the area of ​​the fixing portion 312 covered by the flexible member 500 is the first connection area, which is not exposed in the figure, and the arrow points to the flexible member 500 as a schematic diagram), a second connection area 3122 and a third connection area 3123. The first connection area 3121 is connected to the second connection area 3122. The third connection area 3123 may be randomly distributed at other positions of the first support frame 310 except the first connection area 3121 and the second connection area 3122. The flexible member 500 is fixedly connected to the first connection area 3121. The second connection area 3122 may be fixedly connected to the first shell 20 by gluing or welding. The third connection area 3123 may be fixedly connected to the first shell 20 by screws 370. Exemplarily, the second connection area 3122 may be fixedly connected to the first shell 20 by gluing.

[0142] It is understandable that the fixing portion 312 can be fixedly connected to the first housing 20 by two connection methods, namely, bonding and screw 370. Compared with the solution of using only one connection method, the fixing portion 312 and the first housing 20 are fixedly connected by multiple fixed connection methods, and the connection reliability between the fixing portion 312 and the first housing 20 is higher. In addition, compared with the solution of fixing the first support frame 310 and the first housing 20 only with screws 370, the present embodiment uses both gluing and screw 370 locking methods to fix, which can reduce the length L of the screw 370 and reduce the thickness of the first housing 20 at the connection.

[0143] Exemplarily, the fixing portion 312 of the first support frame 310 may include a first surface 313 and a second surface 314 disposed opposite to each other. The first surface 313 faces the middle plate 21 side of the first shell 20. The second surface 314 faces the cover plate 2 side. A connecting layer 600 is provided between the first surface 313 and the middle plate 21. The connecting layer 600 is connected between the first surface 313 and the middle plate 21. Exemplarily, the connecting layer 600 may be an adhesive layer formed after the glue is cured in the adhesive method, or may be a welding layer formed after the solder is welded.

[0144] Exemplarily, the folding mechanism 300 may further include a screw 370. The third connection area 3123 is provided with a connection hole 315. The connection hole 315 may penetrate the first surface 313 and the second surface 314. A portion of the screw 370 may be fixed in the connection hole 315, and a portion may be fixed to the middle plate 21 of the first housing 20 through the connection hole 315.

[0145] Exemplarily, the length L of the screw 370 may be in the range of 1.2 mm to 1.5 mm. For example, the length L may be 1.2 mm, 1.3 mm, 1.4 mm or 1.5 mm.

[0146] In some embodiments, the side surface of the screw 370 away from the middle plate 21 is located in the connection hole 315. In this way, the screw 370 will not affect other electronic devices of the accessory.

[0147] In some embodiments, the number of screws 370 may be multiple, and the arrangement of the multiple screws 370 is asymmetrical. It is understandable that, compared with the solution using only one connection method, the fixing portion 312 and the first housing 20 are fixedly connected by multiple fixed connection methods, the fastening force required for the screws 370 is reduced, and there is no symmetry requirement for the fixing position of the screws 370. The arrangement of the screws 370 may be asymmetrical, also known as discrete arrangement, and the screws 370 may be more convenient to avoid the internal components (such as the drive component 30 and the electrical connection component 40) of the display device 100.

[0148] In other embodiments, the first support frame 310 may not be provided with the third connection area 3123 , and may be fixedly connected to the first shell body 20 only by gluing or welding.

[0149] In some embodiments, the first support frame 310 may have a laser engraving layer (not shown) on one side facing the first housing 20. The first surface 313 may be the surface of the laser engraving layer. The laser engraving layer may be formed by a laser engraving process. It is understood that the surface energy of the first surface 313 formed by the laser engraving layer is relatively high, and the oil stains on the surface of the first support frame 310 during the assembly process of the electronic device 1000 can be removed. Exemplarily, the surface energy of the first surface 313 may be greater than the dyne value 32.

[0150] like Fig.13 and Fig.14 As shown, the first connection area 3121 can surround the second connection area 3122, and the second connection area 3122 is fixedly connected to the first housing 20 by gluing. That is, the flexible member 500 can be connected around the connection layer 600. The connection layer 600 is a glue layer formed after the glue is cured. It can be understood that during the assembly process of the electronic device 1000, before the glue is cured, the flexible member 500 can be used to prevent the glue from flowing out of the pre-fixed position.

[0151] In some embodiments, the flexible member 500 may include a plurality of sub-parts, which are fixed to the first surface 313 of the first support frame 310 at intervals. In this way, it is easier to assemble the flexible member 500 to the first support frame 310. Fig.14 Schematically, the flexible member 500 includes two sub-parts spaced apart from each other.

[0152] In some embodiments, the assembly steps of the folding mechanism 300 and the first shell 20 may include: first fixing the flexible member 500 (adhesive backing) on ​​the first support frame 310, applying glue at a fixed position on the first shell 20, and then pressing and fixing the first support frame 310 relative to the first shell 20, the flexible member 500 (adhesive backing) is connected between the first support frame 310 and the first shell 20, the flexible member 500 (adhesive backing) is roughly annular, and the glue application position may be inside the flexible member 500 (adhesive backing). After the glue is cured, a connection layer 600 is formed. Then, screws are passed through the connection holes 315 of the first support frame 310 to lock the first support frame 310 and the first shell 20.

[0153] In some embodiments, the assembly steps of the folding mechanism 300 and the first housing 20 may include: after fixing the adhesive on the first support frame 310, covering the surface of the adhesive with a release film, the release film may be used to prevent oil pollution during the assembly process. It is understood that after the other processes are completed, the release film is torn off, and then the first support frame 310 is fixed to the first housing 20.

[0154] Fig.15 yes Figure 3 FIG. 4 is a partial cross-sectional view of an embodiment of the folding mechanism 300 and the input device 200 after being assembled at the section line DD.

[0155] like Fig.15 As shown, the second bracket 320 can be fixed to the second housing 220. Exemplarily, the second bracket 320 can be fixed to the second housing 220 by screws 370.

[0156] In some embodiments, the folding mechanism 300 may include two second supports 320 , and the two second supports 320 are fixed to the second housing 220 at intervals. Both ends of the shaft core 330 are slidably connected to the second supports 320 .

[0157] Fig.16 for Figure 1 A partial cross-sectional view of one embodiment of the electronic structure shown in FIG. 1 at the section line EE.

[0158] like Fig.15 and Fig.16 As shown, the first support frame 310 of the folding mechanism 300 can be fixedly connected to the first housing 20, and the second support frame 320 can be fixedly connected to the second housing 220. The first support frame 310 is rotatably connected to the second support frame 320 via the shaft core 330. In this way, the first housing 20 can be rotated relative to the second housing 220 through the folding mechanism 300, so that the electronic device 1000 can be switched between an open state and a closed state.

[0159] In some embodiments, when the electronic device 1000 is in a closed state, the display device 100 and the input device 200 may be arranged relative to each other. The display screen 10 may be located inside the first housing 20, the display screen 10 may be fixed to the first housing 20, and arranged facing the second housing 220. The input module 210 may be located inside the second housing 220, the input module 210 may be fixed to the second housing 220, and arranged facing the first housing 20. In this way, the display screen 10 and the input module 210 may be located between the first housing 20 and the second housing 220, and the first housing 20 and the second housing 220 may protect the display screen 10 and the input module 210.

[0160] In some embodiments, the number of folding mechanisms 300 may be two, and the two folding mechanisms 300 may be arranged at intervals along the length direction (X-axis direction) of the electronic device 1000. In this way, the rotational connection reliability of the first housing 20 and the second housing 220 is higher. In other embodiments, the number of folding mechanisms 300 may also be one or more than two.

[0161] In other embodiments, the display screen 10 may be fixed to the first housing 20 and disposed facing away from the second housing 220 .

[0162] In some embodiments, the fixing portion 312 of the first support frame 310 can be fixedly connected between the first shell 20 and the display screen 10, and is arranged opposite to the display area of ​​the display screen 10. That is, in the thickness direction of the display panel 1, the fixing portion 312 is at least partially stacked with the display panel 1. It can be understood that compared with the solution in which the first support frame 310 and the display panel 1 are staggered in the thickness direction of the display panel 1, in this embodiment, the fixing portion 312 of the first support frame 310 is arranged in the display area and stacked with the display panel 1, which is conducive to reducing the bottom edge width of the non-display area ("black frame") and improving the screen-to-body ratio of the electronic device 1000.

[0163] Exemplarily, the fixing portion 312 can be fixedly connected to the thin portion 212 of the middle plate 21. It can be understood that the thickness of the thin portion 212 of the middle plate 21 is less than the thickness of the thick portion 211. The fixing portion 312 is fixedly connected to the thin portion 212 of the middle plate 21, and the thickness of the fixing portion 312 after superimposing the thin portion 212 can be within a smaller range. When the fixing portion 312 and the display panel 1 are arranged relative to each other, the fixing portion 312 is reduced from squeezing the original electronic devices between the display panel 1 and the first housing 20.

[0164] In some embodiments, the rotating portion 311 of the first support frame 310 includes a first connecting section 3111 ( Fig.16The first connecting section 3111 of the rotating part 311 and other structural parts are schematically distinguished by dashed lines, and the first connecting section 3111 is fixedly connected to one side of the fixing part 312 of the first support frame 310. The first connecting section 3111 is in an arc shape, and the projection of the first connecting section 3111 on the first shell 20 along the first direction overlaps with the first shell 20 at least partially, and the angle between the extension direction of the first connecting section 3111 and the thickness direction of the display screen 10 is less than or equal to 10°.

[0165] It can be understood that the transition section from the rotating part 311 to the fixed part 312 (that is, the first connecting section 3111) is roughly parallel to the thickness direction of the display screen 10, so that the part of the first support frame 310 fixed under the display panel 1 is as parallel to the first shell 20 as possible, and the length of the first support frame 310 in the first accommodating space 50 and the inclined setting of the display panel 1 is minimized as much as possible, which is beneficial to reducing the bottom edge width of the "black frame" of the electronic device 1000 and improving the screen-to-body ratio of the electronic device 1000.

[0166] like Fig.16 As shown, one end of the signal transmission structure 400 can be electrically connected to the display device 100, and the other end can be electrically connected to the input device 200. Exemplarily, one end of the signal transmission structure 400 can be electrically connected to the driving assembly 30 of the display device 100, and the other end can pass through the folding mechanism 300 into the second housing 220 and be electrically connected to the mainboard of the input device 200.

[0167] In some embodiments, the signal transmission structure 400 may include a flexible circuit board 410. One end of the flexible circuit board 410 may be electrically connected to the display device 100, may pass through the folding mechanism 300 to enter the second housing 220, and be electrically connected to the input device 200. Exemplarily, the folding mechanism 300 may have a threading channel 360. A portion of the flexible circuit board is located in the display device 100 and is electrically connected to the display device 100, and the other end passes through the threading channel 360 to enter the input device 200 and is electrically connected to the input device 200.

[0168] Exemplarily, the flexible circuit board 410 may be partially located in the first accommodation space 50 for electrically connecting to the driving assembly 30 , partially located in the threading channel 360 , and partially located in the second accommodation space 250 for electrically connecting to the mainboard.

[0169] It is understandable that, compared with the solution of using a cable to pass through the folding mechanism 300, the thickness of the flexible circuit board 410 is smaller than the cable line, and the bending radius of the flexible circuit board 410 when entering the threading channel 360 of the folding mechanism 300 can be smaller, and the cover plate 2 can use more area to set the display panel 1, thereby reducing the border width of the electronic device 1000 and improving the screen ratio of the electronic device 1000. Exemplarily, compared with the cable line, the reduction in the bending radius of the flexible circuit board 410 before entering the folding mechanism 300 can be in the range of 2mm to 3mm. For example, 2.0mm, 2.5mm or 3.0mm.

[0170] In some embodiments, the flexible circuit board 410 can be electrically connected to the circuit board of the drive assembly 30 through an electrical connector. The signal of the main board is transmitted to the driver through the flexible circuit board 410, the electrical connector, and the circuit board. Exemplarily, the electrical connector can be a board-to-board connector (BTB) or a zero insertion force connector (ZIF).

[0171] In other embodiments, the signal transmission structure 400 may further include a signal line 420. The signal line 420 may be located in the second housing 220. The signal line 420 may be connected to the flexible circuit board 410 in the second housing 220 at one end and connected to the main board of the input device 200 at the other end. The signal line 420 may be used to implement electrical signal transmission between the flexible circuit board 410 and the main board.

[0172] In some embodiments, the flexible circuit board 410 may be partially fixed to the folding mechanism 300. For example, a portion of the flexible circuit board 410 may be fixedly connected to the rotating portion 311 of the first support frame 310. In this way, the risk of shaking of the flexible circuit board 410 may be reduced, and the reliability of electrical connection is better.

[0173] In other embodiments, there may be multiple signal transmission structures 400, and the multiple signal transmission structures 400 may be used for electrical signal transmission between different devices in the display device 100 and the input device 200, respectively. For example, the number of signal transmission structures 400 may be two. The display device 100 may also include a camera module (not shown). One end of one of the signal transmission structures 400 may be electrically connected to the drive assembly 30 of the display device 100, and the other end may pass through the folding mechanism 300 to enter the second shell 220, and be electrically connected to the mainboard of the input device 200. One end of another signal transmission structure 400 may be electrically connected to the camera module, and the other end may pass through the folding mechanism 300 to enter the second shell 220, and be electrically connected to the mainboard of the input device 200.

[0174] Fig.17 It is a schematic diagram of partial structural assembly of an implementation method of the signal transmission structure 400 and the first support frame 310 at another angle.

[0175] like Fig.17 As shown, the folding mechanism 300 may include a first positioning structure 371 and a second positioning structure 372. The first positioning structure 371 and the second positioning structure 372 may be used to assist in fixing the position of the flexible circuit board 410 on the folding mechanism 300. Exemplarily, the first positioning structure 371 and the second positioning structure 372 may be fixed to the first support frame 310 at intervals along the second direction. The first positioning structure 371 and the second positioning structure 372 may be located in the threading channel 360. The flexible circuit board 410 may be partially located between the first positioning structure 371 and the second positioning structure 372. The second direction may be the width direction of the threading channel 360. It is understood that during the opening and closing process of the electronic device 1000, the first positioning structure 371 and the second positioning structure 372 may reduce the risk of shaking of the flexible circuit board 410.

[0176] In some embodiments, the rotating portion 311 of the first support 310 may be provided with a threading groove 316, and the shaft cover 340 may be fixedly connected to the rotating portion 311, covering the threading groove 316 to form a threading channel 360. The flexible circuit board 410 may be partially located in the threading groove 316. The first positioning structure 371 and the second positioning structure 372 may be located in the threading groove 316. Exemplarily, the first positioning structure 371 and the second positioning structure 372 may be fixed to one end of the rotating portion 311 close to the fixed portion 312.

[0177] In some embodiments, the relationship between the distance K between the first positioning structure 371 and the second positioning structure 372 along the second direction and the width N of the flexible circuit board satisfies:

[0178] 1≤K / N≤1.02.

[0179] It can be understood that the distance between the first positioning structure 371 and the second positioning structure 372 along the second direction is substantially equal to the width N of the flexible circuit board 410 , which is beneficial to positioning the flexible circuit board 410 on the folding mechanism 300 .

[0180] In some embodiments, the first positioning structure 371 can be an integral structure with the first support frame 310. The second positioning structure 372 can be an integral structure with the first support frame 310. In this way, the connection strength between the first positioning structure 371 and the first support frame 310 is better. The connection strength between the second positioning structure 372 and the first support frame 310 is better.

[0181] In some embodiments, due to the limitation of the preparation process, the obtained flexible circuit board 410 will have redundancy in the width direction and the length direction. In the process of assembling the flexible circuit board, the drawing direction of the flexible circuit board 410 can be set to the direction from the fixed part 312 of the first support frame 310 to the rotating part 311. In this way, the redundancy of the flexible circuit board 410 in the length direction can be placed in the second accommodating space 250. It can be understood that compared with the solution of placing the redundancy of the flexible circuit board 410 in the length direction in the first accommodating space 50, placing the redundancy of the flexible circuit board 410 in the second accommodating space 250 can reduce the volume of the flexible circuit board 410 in the first accommodating space 50, and reduce the probability of damage to the electrical connection component 40 caused by the arching of the flexible circuit board 410.

[0182] Fig.18 yes Figure 1 A partial cross-sectional view of one embodiment of the electronic structure shown in FIG. 1 at the section line EE.

[0183] like Fig.18 As shown, the electronic device 1000 may further include a stopper 700. The stopper 700 may be fixed to the same side of the display screen 10 as the electrical connection assembly 40. The stopper 700 may be located in the first accommodation space 50. Exemplarily, the stopper 700 may be fixed to the cover plate 2 and spaced apart from the first housing 20. A portion of the flexible circuit board 410 may be located between the stopper 700 and the first housing 20. Exemplarily, a portion of the flexible circuit board 410 may be located between the stopper 700 and the first support frame 310.

[0184] In some embodiments, the distance between the stopper 700 and the first housing 20 is smaller than the distance between the electrical connection assembly 40 and the first housing 20. The distance between the stopper 700 and the first housing 20 is measured along the thickness direction of the display screen 10. The distance between the electrical connection assembly 40 and the first housing 20 is measured along the thickness direction of the display screen 10. It is understood that the stopper 700 can be used to prevent the flexible circuit board 410 from arching too much and squeezing the electrical connection assembly 40 during the opening and closing process of the electronic device 1000.

[0185] For example, the material of the first support frame 310 can be rubber, so that the hardness of the limiter 700 is relatively small, which can reduce the risk of damage to the flexible circuit board 410.

[0186] In some embodiments, the same parts as those in the above embodiments are not described in detail here. Fig.19 yes Fig.18 A partial cross-sectional view of another embodiment of the structure shown in FIG.

[0187] like Fig.19As shown, the stopper 700 may include a main body 710 and an extension 720. The main body 710 may be fixedly connected to the display screen 10, and one end of the extension 720 is connected to an end of the main body 710 away from the display screen 10. The extension 720 may be arranged at an angle with the main body 710, and the electrical connection assembly 40 may be located on a side of the extension 720 away from the flexible circuit board 410. Exemplarily, the main body 710 may be fixedly connected to the cover plate 2 of the display screen 10.

[0188] It can be understood that at least a portion of the electrical connection component 40 is placed on the side of the extension portion 720 away from the first shell 20, and the extension portion 720 can be located between the flexible circuit board 410 and the electrical connection component 40. During the opening and closing process of the electronic device 1000, the limit member 700 can protect the electrical connection component 40, further reducing the risk of squeezing the electrical connection component 40 due to excessive arching of the flexible circuit board 410.

[0189] For example, the cross section of the stopper 700 in the YZ plane may be approximately Z-shaped. In this case, the main body 710 may be approximately L-shaped. The extension portion 720 may be approximately I-shaped.

[0190] Exemplarily, the material of the limiting member 700 may be rubber or stainless steel.

[0191] In some embodiments, the same parts as those in the above embodiments are not described in detail here. Fig. 20 yes Fig.17 A cross-sectional view of another embodiment of the structure shown in FIG.

[0192] like Fig. 20 As shown, there is a gap between the wall of the threading channel 360 and the flexible circuit board 410. The ratio of the width of the gap to the width of the flexible circuit board 410 can be between 5% and 15%. In other words, the relationship between the width M of the threading channel 360 and the width N of the flexible circuit board satisfies:

[0193] 1.05≤M / N≤1.15.

[0194] Exemplarily, when the width of the flexible circuit board 410 is in the range of 11 mm to 13 mm, the width of the gap may be in the range of 0.8 mm to 1.2 mm.

[0195] It can be understood that a larger gap is reserved between the threading channel 360 and the flexible circuit board 410. When the flexible circuit board 410 passes through the threading channel 360, the routing direction of the flexible circuit board 410 can be set at an angle to the length direction of the threading channel 360. The gap can be used to accommodate the redundancy of the flexible circuit board 410 in the width direction, thereby reducing the risk of the flexible circuit board 410 in the first accommodating space 50 arching and squeezing the electrical connection component 40.

[0196] The present application discloses an electronic device 1000 in conjunction with the accompanying drawings. The electronic device includes a display device 100, an input device 200 and a folding mechanism 300. The folding mechanism 300 is connected to the display device 100 and the input device 200. The display device 100 and the input device 200 are relatively unfolded or folded through the folding mechanism 300. The folding mechanism 300 includes a first support frame 310. The first support frame 310 includes a fixed portion 312 and a rotating portion 311. The rotating portion 311 is fixedly connected to the fixed portion 312. The display device 100 includes a display screen 10 and a first shell 20. The display screen 10 is installed on the first shell 20. The fixed portion 312 of the first support frame 310 is fixedly connected between the first shell 20 and the display screen 10, and is arranged opposite to the display area AA of the display screen 10. The rotating portion 311 of the first support frame 310 is rotatably connected to the input device 200. The electronic device 1000 further includes a flexible member 500 . The flexible member 500 is fixed between the fixing portion 312 of the first support frame 310 and the first housing 20 . The hardness of the flexible member 500 is less than that of the first housing 20 .

[0197] It can be understood that the fixing portion 312 of the first support frame 310 is fixedly connected to the first housing 20 and is arranged opposite to the display area AA of the display screen 10, that is, the fixing position of the fixing portion 312 overlaps with the display area AA, and the fixing portion 312 can be arranged on the back of the display area AA. The back of the display area AA refers to the side facing away from the display surface.

[0198] Compared with the solution in which the fixing portion 312 of the first support frame 310 is fixed to the non-display area of ​​the display screen 10, the present application fixes the fixing portion 312 of the first support frame 310 to the back of the display area AA of the display screen 10, which does not need to occupy the area of ​​the non-display area, can reduce the area of ​​the non-display area of ​​the display screen 10, and the frame of the electronic device 1000 is narrower. At the same time, the non-display area originally used to set the fixing portion 312 can also be used for display, further increasing the display area of ​​the electronic device 1000, which is conducive to improving the screen-to-body ratio of the electronic device 1000. The screen-to-body ratio can be the ratio of the area of ​​the display area of ​​the display device 100 (that is, the display area AA of the display screen 10) to the area of ​​the non-display area of ​​the display device 100.

[0199] It can be understood that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of the present application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0200] It is understood that all the above drawings are exemplary illustrations of the present application and do not represent the actual size of the product. Moreover, the size ratio relationship between the components in the drawings is not intended to limit the actual product of the present application.

[0201] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
