Description

Technical Field

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

[0002] With the advancement of technology, the form factor of electronic devices (such as mobile phones and tablets) is trending from candy-bar devices to foldable devices. Foldable devices offer large screens when open, fully satisfying consumers' visual experience, while being compact and portable when closed. However, existing foldable electronic devices are still relatively thick, failing to meet user demands for thinner and lighter foldable devices. Summary of the Invention

[0003] The present application provides a rotating mechanism and a foldable electronic device, which can solve the technical problem of large thickness of foldable electronic devices in the prior art.

[0004] In a first aspect, the present application provides a rotation mechanism. The rotation mechanism is applied to a foldable electronic device. The foldable electronic device includes a first housing, a second housing, a display screen, and a rotation mechanism. The rotation mechanism includes a base, a first rotating portion, a second rotating portion, and a door panel assembly. The first rotating portion and the second rotating portion are arranged opposite each other along the width direction of the base and are both rotatably connected to the base.

[0005] The door panel assembly includes a first door panel, a second door panel, and an intermediate door panel. The door panel assembly is located on top of the base. The intermediate door panel is mounted to the base, the first door panel is mounted to the first rotating portion, and the second door panel is mounted to the second rotating portion. Furthermore, the first door panel and the second door panel are located on opposite sides of the intermediate door panel in the width direction.

[0006] The first door panel includes a first surface and a second surface. The first surface and the second surface are arranged opposite each other along the thickness direction of the first door panel, and the second surface faces the first rotating portion. The first surface is an inclined surface. When the first rotating portion and the second rotating portion are relatively extended, the angle between the first surface and the width direction of the base is greater than 0 degrees and less than 90 degrees. The first surface is inclined toward the bottom of the base along the direction from the middle door panel to the first door panel.

[0007] The rotation mechanism is disposed between the first and second housings. The first rotation portion is connected to the first housing, and the end of the first door panel facing away from the middle door panel is located within the first housing, with the first surface facing the inner surface of the first housing. The second rotation portion is fixedly connected to the second housing, and the end of the second door panel facing away from the middle door panel is located within the second housing. The display screen is mounted to the first and second housings, and is located at the bottom of the base, that is, on the side of the base facing away from the middle door panel.

[0008] When the rotating mechanism rotates, the first rotating part and the second rotating part rotate relative to each other, the first door panel and the second door panel rotate relative to each other, the first shell and the second shell rotate relative to each other, the first door panel slides relative to the first shell, the second door panel slides relative to the second shell, and drives the display screen to bend or unfold.

[0009] The first shell and the second shell have opposite rotation directions, the first rotating portion and the second rotating portion have opposite rotation directions, and the first door panel and the second door panel have opposite rotation directions.

[0010] It should be noted that the top and bottom of the base refer to two opposite sides along the thickness direction of the base. When the first rotating part and the second rotating part are relatively unfolded, the angle between the first rotating part and the second rotating part is approximately 180 degrees, that is, the rotating mechanism is in the unfolded state.

[0011] In this embodiment, by setting the first surface of the first door panel as a slope, and when the first rotating part and the second rotating part are relatively unfolded, the first surface is inclined toward the bottom direction of the base along the direction from the middle door panel to the first door panel, the distance from the end of the first door panel close to the middle door panel to the back side of the first shell (the surface facing away from the display screen) can be reduced in the thickness direction of the rotating mechanism, that is, the distance between the base and the back side of the first shell is reduced, so that the foldable electronic device is more compact in the thickness direction, thereby reducing the thickness of the foldable electronic device, which is conducive to achieving the lightweight and thinness of the foldable electronic device.

[0012] When the thickness of the foldable electronic device is constant, the foldable electronic device provided in this embodiment has a smaller distance from the base of the rotating mechanism to the back of the first shell (the surface facing away from the display screen) in the thickness direction of the foldable electronic device, and a larger thickness of the rotating mechanism, thereby increasing the thickness of the base, the first rotating member and the second rotating member, especially increasing the thickness of the axis area of ​​the rotating mechanism, thereby improving the structural strength, rotational stability and reliability of the rotating mechanism, and improving the structural strength and rotational stability of the foldable electronic device.

[0013] In one possible embodiment, the first surface is a concave slope that curves toward the second surface. The first surface includes a first end and a second end. The first end and the second end are disposed opposite each other along the width of the first surface, with the second end located on a side closer to the middle door panel. The curvature of the first surface gradually decreases from the second end to the first end.

[0014] In this embodiment, by configuring the first surface as a concave slope, the curvature of the first surface better matches the rotation angle of the first door panel relative to the first housing when the rotating mechanism rotates, thereby improving the smoothness and stability of the rotation of the rotating mechanism and the foldable electronic device. Furthermore, this provides a margin for error in the rotation of the first door panel, preventing interference between the first door panel and the first housing.

[0015] In a possible implementation manner, when the first rotating portion and the second rotating portion are relatively unfolded, a height difference between the second end and the first end along the thickness direction of the base is 0.3 mm to 0.6 mm.

[0016] In this embodiment, by setting the height difference between the second end and the first end to 0.3mm~0.6mm, the minimum distance from the first door panel to the back of the first shell can be reduced without affecting the rotation of the foldable electronic device, thereby reducing the distance from the top of the rotating mechanism to the back of the first shell, and then reducing the thickness of the foldable electronic device.

[0017] In one possible embodiment, the first rotating portion includes a first swing arm assembly and a first fixed bracket. The first fixed bracket is mounted on the first swing arm assembly and is rotatably connected to the base. The first fixed bracket is provided with a first slide groove, the first slide groove extending parallel to the width of the first fixed bracket. The door panel assembly also includes a first slider. The first slider is fixedly connected to the first door panel and mounted in the first slide groove, and the first slider is capable of sliding along the first slide groove.

[0018] In this embodiment, by setting a first slider on the first door panel and a first sliding groove on the first fixed frame, a sliding connection between the first door panel and the first fixed frame can be achieved, so that when the rotating mechanism rotates from the unfolded state to the folded state, the first door panel can move in the direction away from the middle door panel, thereby avoiding interference between the first door panel and the middle door panel and improving the smoothness and stability of the rotation of the rotating mechanism.

[0019] In one possible embodiment, the first swing arm assembly includes a first door panel swing arm. One end of the first door panel swing arm is rotatably connected to the base, and the other end is slidably connected to the first fixing bracket. The first fixing bracket is slidable relative to the first door panel swing arm along the width direction of the first fixing bracket. The first door panel is fixedly connected to the first door panel swing arm.

[0020] In this embodiment, by fixedly connecting the first door panel and the first door panel swing arm, when the rotating mechanism rotates, the first fixing frame and the first door panel swing arm simultaneously drive the first door panel to rotate, thereby improving the stability of the rotation of the first door panel.

[0021] In one possible embodiment, a first protrusion is provided on a side of the middle door panel facing the first door panel. The first surface is located on a side of the first protrusion away from the base. Along the thickness direction of the base, an orthographic projection of the second end is flush with an outer surface of the first protrusion, or the orthographic projection of the second end coincides with the first protrusion.

[0022] In this embodiment, by providing a first protrusion on the middle door panel and making the orthographic projection of the first surface flush with or coincident with the outer surface of the first protrusion, the gap between the middle door panel and the first door panel along the width direction of the base can be reduced or avoided, thereby improving the refinement of the appearance of the foldable electronic device.

[0023] In one possible embodiment, the second door panel includes a third surface and a fourth surface. The third and fourth surfaces are arranged opposite each other along the thickness direction of the second door panel, and the fourth surface faces the second rotating portion. The second surface is an inclined surface. When the first rotating portion and the second rotating portion are relatively unfolded, the angle between the second surface and the width direction of the base is greater than 0 degrees and less than 90 degrees. Along the direction from the middle door panel to the second door panel, the second surface is inclined toward the bottom of the base.

[0024] In this embodiment, by setting the second surface of the second door panel as a slope, and tilting the second surface toward the second rotating part along the direction from the middle door panel to the second door panel, the distance from the end of the second door panel close to the middle door panel to the back of the second shell (the surface facing away from the display screen) can be reduced in the thickness direction of the rotating mechanism, that is, the distance between the base and the back of the second shell is reduced, making the foldable electronic device more compact in the thickness direction, thereby reducing the thickness of the foldable electronic device, which is conducive to achieving the lightweight and thinness of the foldable electronic device.

[0025] In one possible embodiment, the second rotating portion includes a second door panel swing arm and a second fixed frame. One end of the second door panel swing arm is rotatably connected to the base, and the other end is slidably connected to the second fixed frame. The second fixed frame is slidable relative to the second door panel swing arm along the width of the second fixed frame. The second door panel is fixedly connected to the second door panel swing arm and slidably connected to the second fixed frame.

[0026] In this embodiment, the second door panel is fixedly connected to the second door panel swing arm and slidably connected to the second fixing bracket. When the rotation mechanism rotates, the second fixing bracket and the second door panel swing arm jointly drive the second door panel to rotate, thereby improving the stability of the second door panel's rotation. Furthermore, in this embodiment, the sliding connection between the second door panel and the second fixing bracket allows the second door panel to move away from the middle door panel when the rotation mechanism rotates from the deployed state to the folded state. This prevents interference between the second door panel and the middle door panel, further improving the smoothness and stability of the rotation of the rotation mechanism.

[0027] In a second aspect, the present application provides a foldable electronic device comprising a first housing, a second housing, a display screen, and the aforementioned rotation mechanism. The rotation mechanism is disposed between the first and second housings. The first rotation portion is connected to the first housing, the end of the first door panel away from the middle door panel is located within the first housing, and the first surface faces the inner surface of the first housing. The second rotation portion is connected to the second housing, and the end of the second door panel away from the middle door panel is located within the second housing. The display screen is mounted to the first and second housings, the rotation mechanism, and is located at the bottom of the base.

[0028] When the rotating mechanism rotates, the first shell and the second shell rotate relative to each other, the first door panel slides relative to the first shell, and the second door panel slides relative to the second shell, driving the display screen to bend or unfold.

[0029] In the foldable electronic device provided in the embodiment of the present application, the rotating mechanism and the first shell and the second shell are arranged more compactly along the thickness direction of the foldable electronic device, and the thickness of the foldable electronic device is smaller and thinner.

[0030] In one possible embodiment, the first housing includes a first cover plate, a first middle frame, and a first support block. The first cover plate is located on a side of the first middle frame facing away from the display screen and is fixedly connected to the first middle frame. The first support block is fixed to a surface of the first cover plate facing the first middle frame. The first support block includes a first support surface, which is an inclined surface, and the inclination angle of the first support surface is consistent with the inclination angle of the first surface.

[0031] When the first shell and the second shell are relatively unfolded, the first surface and the surface of the first cover plate facing away from the first middle frame are oriented in the same direction, and the first door panel and the first support block are arranged along the width direction of the base. When the first shell and the second shell are relatively folded, the first door panel and the first support block are arranged opposite each other along the thickness direction of the first shell, and the first surface faces the first support block and is parallel to and in contact with the first support surface.

[0032] In this embodiment, by arranging a first support block on the inner surface of the first cover plate, and when the foldable electronic device is in a folded state, the first support block is arranged opposite to the first door panel, so that the first support block supports the first door panel, which can prevent the first cover plate from scratching the first door panel and affecting the appearance of the first door panel. At the same time, it can also reduce the pressure of the first door panel on the first cover plate, thereby avoiding the formation of mold marks on the first cover plate and improving the sophistication of the foldable electronic device.

[0033] Furthermore, in this embodiment, by setting the inclination angle of the first support surface to be consistent with the inclination angle of the first surface, the first surface can move along the first support surface to be arranged opposite the first support block during the rotation of the foldable electronic device from the unfolded state to the folded state, thereby improving the smoothness of the movement of the first door panel relative to the first support block, thereby improving the smoothness and stability of the rotation process of the foldable electronic device. At the same time, when the rotating mechanism is in the folded state, the first support surface is parallel to and in contact with the first surface, thereby increasing the contact area between the first door panel and the first support block, thereby improving the support stability of the first support block on the first door panel, and improving the connection stability between the first door panel and the first housing.

[0034] In summary, the rotating mechanism provided in the present application, by setting the first surface of the first door panel as a slope, and when the first rotating part and the second rotating part are relatively unfolded, the first surface is inclined toward the bottom direction of the base along the direction from the middle door panel to the first door panel. The distance from the end of the first door panel close to the middle door panel to the back side of the first shell (the surface facing away from the display screen) can be reduced in the thickness direction of the rotating mechanism, that is, the distance between the base and the back side of the first shell is reduced, so that the foldable electronic device is more compact in the thickness direction, thereby reducing the thickness of the foldable electronic device, which is conducive to realizing the lightweight and thinness of the foldable electronic device.

[0035] When the thickness of the foldable electronic device is constant, the foldable electronic device of the present application has a smaller distance from the base of the rotating mechanism to the back of the first shell in the thickness direction of the foldable electronic device, and the thickness of the rotating mechanism is larger, thereby increasing the thickness of the base, the first rotating member and the second rotating member, especially increasing the thickness of the axis area of ​​the rotating mechanism, thereby improving the structural strength, rotational stability and reliability of the rotating mechanism, and improving the structural strength and rotational stability of the foldable electronic device.

[0062] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0063] See also Figures 1 to 3 , Figure 1 1 is a schematic structural diagram of a foldable electronic device 1000 provided in an embodiment of the present application in a first state. Figure 2 is a structural diagram of the foldable electronic device 1000 provided in an embodiment of the present application in the second state, Figure 3 3 is a schematic structural diagram of the foldable electronic device 1000 provided in an embodiment of the present application in the third state.

[0064] The foldable electronic device 1000 includes, but is not limited to, a cell phone, a notebook computer, a tablet personal computer, a laptop computer, a personal digital assistant, a wearable device, or a mobile device. In the embodiment of the present application, the foldable electronic device 1000 is described as a cell phone.

[0065] in, Figure 1 The foldable electronic device 1000 is shown in a folded state. Figure 2 The foldable electronic device 1000 is shown in a semi-expanded state. Figure 3 The foldable electronic device 1000 is shown in an unfolded state. Figure 2 The unfolding angle α of the foldable electronic device 1000 is 90 degrees. Figure 3 The unfolding angle β of the foldable electronic device 1000 is shown to be 180 degrees.

[0066] It should be noted that the angles illustrated in the embodiments of this application are allowed to have slight deviations. For example, Figure 2 The unfolding angle α of the foldable electronic device 1000 shown is 90 degrees, which means that α can be 90 degrees or approximately 90 degrees, such as 80 degrees, 85 degrees, 95 degrees or 100 degrees. Figure 3The unfolding angle β of the foldable electronic device 1000 shown is 180 degrees, which means that β can be 180 degrees or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees. The angles described below as examples can be understood in the same way.

[0067] The foldable electronic device 1000 shown in the embodiment of the present application is a foldable electronic device 1000 that can be folded once. In other embodiments, the foldable electronic device 1000 can also be a foldable electronic device 1000 that can be folded multiple times (more than twice). In this case, the foldable electronic device 1000 may include multiple parts, where two adjacent parts can be folded relatively close together until the foldable electronic device 1000 is in a folded state, and two adjacent parts can be unfolded relatively far apart until the foldable electronic device 1000 is in an unfolded state.

[0068] For ease of description, the width direction of the foldable electronic device 1000 in the unfolded state is defined as the X direction, the length direction is defined as the Y direction, and the thickness direction is defined as the Z direction. The X direction, the Y direction, and the Z direction are perpendicular to each other.

[0069] See also Figure 4 , Figure 4 yes Figure 3 A schematic diagram of the exploded structure of the foldable electronic device 1000 is shown.

[0070] The foldable electronic device 1000 includes a first shell 200, a second shell 300, a rotating mechanism 100 and a display screen 400. The rotating mechanism 100 is connected between the first shell 200 and the second shell 300 to achieve a rotating connection between the first shell 200 and the second shell 300. The display screen 400 includes a first portion 410, a second portion 420 and a foldable portion 430. The foldable portion 430 is located between the first portion 410 and the second portion 420, and the foldable portion 430 can be bent around the axis in the Y direction. In this embodiment, the display screen 400 uses a flexible display screen, such as an organic light-emitting diode (OLED) display screen, an active matrix organic light-emitting diode (AMOLED) display screen, etc.

[0071] The display screen 400 is mounted on the same side of the first housing 200, the second housing 300, and the rotating mechanism 100 in the Z direction. The first portion 410 is mounted on the first housing 200, the second portion 420 is mounted on the second housing 300, and the foldable portion 430 is positioned opposite the rotating mechanism 100. When the rotating mechanism 100 rotates, it drives the first housing 200 and the second housing 300 to rotate relative to each other, thereby causing the display screen 400 to fold or unfold, allowing the foldable electronic device 1000 to switch between an unfolded state and a folded state.

[0072] Combine Figure 1 When the rotating mechanism 100 rotates and drives the first shell 200 and the second shell 300 to rotate in a direction close to each other, the display screen 400 can be folded, so that the foldable electronic device 1000 is folded. In this embodiment, the foldable electronic device 1000 is an external folding machine. When the foldable electronic device 1000 is in a folded state, the foldable portion 430 of the display screen 400 is bent, and the first portion 410 and the second portion 420 are arranged opposite to each other. At this time, the display screen 400 is located on the outside of the foldable electronic device 1000, and the foldable portion 430 has a large bending angle, which can greatly reduce the probability of creases appearing on the foldable portion 430 of the display screen 400. In some other embodiments, the foldable electronic device 1000 can also be an internal folding machine, that is, the display screen 400 can also be folded inward by the rotating mechanism 100. When the display screen 400 folds inward and the foldable electronic device 1000 is in a folded state, the first part 410 and the second part 420 are arranged relative to each other, and the display screen 400 is located between the first shell 200 and the second shell 300, which can greatly reduce the probability of the display screen 400 being damaged and achieve effective protection of the display screen 400.

[0073] See also Figure 2 When the rotating mechanism 100 rotates and drives the first housing 200 and the second housing 300 to rotate away from each other, the display screen 400 can be unfolded, so that the foldable electronic device 1000 is unfolded to a semi-expanded state. When the foldable electronic device 1000 is in the semi-expanded state, the angle between the first housing 200 and the second housing 300 is α, the angle between the first portion 410 and the second portion 420 is α, and the foldable portion 430 is curved. The curvature of the foldable portion 430 when the foldable electronic device 1000 is in the semi-expanded state is smaller than the curvature of the foldable portion 430 when the foldable electronic device 1000 is in the folded state.

[0074] See also Figure 3When the rotating mechanism 100 rotates and drives the first shell 200 and the second shell 300 to rotate further away from each other, the display screen 400 further unfolds until the foldable electronic device 1000 is flattened. When the foldable electronic device 1000 is in the unfolded state, the angle between the first shell 200 and the second shell 300 is β. The foldable part 430 unfolds, and the first part 410 and the second part 420 unfold relative to each other. At this time, the angle between the first part 410 and the second part 420 is β, and the display screen 400 has a large display area, realizing a large-screen display of the foldable electronic device 1000 and improving the user experience.

[0075] It should be noted that angles α and β are both the angles between the first housing 200 and the second housing 300. They are used here only to distinguish the angles between the first housing 200 and the second housing 300 in different states of the foldable electronic device 1000. Angle α refers to the angle between the first housing 200 and the second housing 300 when the foldable electronic device 1000 is in the semi-expanded state; angle β refers to the angle between the first housing 200 and the second housing 300 when the foldable electronic device 1000 is in the expanded state.

[0076] See also Figure 5 and Figure 6 , Figure 5 yes Figure 3 The partially exploded structural diagram of the foldable electronic device 1000 is shown. Figure 6 yes Figure 3 A partial cross-sectional structural diagram of a foldable electronic device 1000 is shown.

[0077] The first shell 200 includes a first cover plate 210, a first middle frame 220, and a first support block 230. The first middle frame 220 includes a first middle plate 240 and a first side frame 250. The first middle plate 240 is a rectangular plate-shaped structure. An installation space is provided on the first middle plate 240. The installation space is used to install components such as the battery and mainboard of the foldable electronic device 1000. A first connecting ear 270 is provided on one side of the first middle plate 240 along the X direction. The first connecting ear 270 is fixedly connected to the first middle plate 240. The first connecting ear 270 is used to be fixedly connected to the rotating mechanism 100.

[0078] The first frame 250 includes a first sub-frame 2501, a second sub-frame 2502, and a third sub-frame 2503. The first sub-frame 2501, the second sub-frame 2502, and the third sub-frame 2503 are connected in sequence and fixedly connected to the outer periphery of the first middle plate 240. The second sub-frame 2502 is arranged on one side of the first middle plate 240 in the X direction and is arranged opposite to the first connecting ear 270. The first sub-frame 2501 and the third sub-frame 2503 are arranged opposite to each other along the Y direction and are connected to opposite ends of the second sub-frame 2502. Along the X direction, the end of the first sub-frame 2501 away from the second sub-frame 2502 protrudes from the edge of the first middle plate 240, and the end of the third sub-frame 2503 away from the second sub-frame 2502 both protrude from the edge of the first middle plate 240. That is, the end of the first sub-frame 2501 away from the second sub-frame 2502 and the end of the third sub-frame 2503 away from the second sub-frame 2502 are both located on the negative side of the first middle plate 240 in the x-axis direction, thereby forming a first mounting opening 260 on a side of the first middle frame 220. The first mounting opening 260 is located on the side of the first middle plate 240 away from the second sub-frame 2502. The first connecting ear 270 is located within the first mounting opening 260.

[0079] In this embodiment, the first cover plate 210 is a rectangular thin plate. The first cover plate 210 is stacked with the first middle frame 220 along the Z direction and is fixedly connected to the first middle frame 220. The size of the first cover plate 210 is larger than the size of the first middle plate 240. Specifically, the size of the first cover plate 210 along the Y direction is equal to or approximately equal to the size of the first middle plate 240 along the Y direction. The size of the first cover plate 210 along the X direction is larger than the size of the first middle plate 240 along the X direction. The first cover plate 210 completely covers the first middle plate 240 in the Z direction and at least partially covers the first mounting opening 260. In this embodiment, the first cover plate 210 completely covers the first mounting opening 260 in the Z direction. That is, the orthographic projection of the first mounting opening 260 along the Z direction is completely located within the first cover plate 210.

[0080] It can be understood that the battery of the foldable electronic device 1000 is installed in the first shell 200, and the first cover 210 can also be understood as the battery cover or back cover of the foldable electronic device 1000.

[0081] In this embodiment, the material of the first support block 230 is POM (polyoxymethylene). In other embodiments, the support block can also be made of other wear-resistant plastics.

[0082] The first support block 230 is fixed to the inner surface of the first cover plate 210. In other words, the first support block 230 is fixed to the surface of the first cover plate 210 facing the first middle plate 240. The first support block 230 faces the first mounting opening 260, and its projection along the Z direction is completely located within the first mounting opening 260.

[0083] In this embodiment, the first support block 230 is wedge-shaped. The first support block 230 includes a first support surface 2301. The first support surface 2301 faces the first mounting opening 260. That is, the first support surface 2301 is the surface of the first support block 230 away from the first cover plate 210, that is, the surface facing the negative direction of the Z axis. The first support surface 2301 is a convex inclined surface and an arc surface. The first support surface 2301 is curved in a direction away from the first cover plate 210, and the angle between the first support surface 2301 and the X direction is greater than 0 degrees and less than 90 degrees. Along the negative direction of the X axis, the first support surface 2301 is inclined toward the negative direction of the Z axis.

[0084] Here, a "convex slope" refers to a slope that slopes gently at the top and steepens at the bottom. That is, along the negative X-axis, the inclination angle of the first support surface 2301 gradually decreases. This means that the angle between the tangent of the first support surface 2301 and the X-direction gradually decreases, and the curvature of the first support surface 2301 gradually decreases. It is understood that along the negative X-axis, the distance from the first support surface 2301 to the first cover plate 210 gradually increases.

[0085] The structure of the second housing 300 is identical or substantially identical to that of the first housing 200. The second housing 300 includes a second middle frame 320, a second cover plate 310, and a second support block 330. The second middle frame 320 includes a second middle plate 340 and a second side frame 350. A second connecting lug 370 is provided on one side of the second middle plate 340 along the X-direction. The second connecting lug 370 is fixedly connected to the second middle plate 340. The second connecting lug 370 is configured to be fixedly connected to the rotating mechanism 100.

[0086] The second frame 350 includes a fourth sub-frame 3501, a fifth sub-frame 3502, and a sixth sub-frame 3503. The fourth sub-frame 3501, the fifth sub-frame 3502, and the sixth sub-frame 3503 are sequentially connected and fixedly attached to the outer periphery of the second middle plate 340. The fifth sub-frame 3502 is disposed on one side of the second middle plate 340 in the X direction and is opposite the second connecting lug 370. The fourth sub-frame 3501 and the sixth sub-frame 3503 are disposed opposite each other in the Y direction and are connected to opposite ends of the fifth sub-frame 3502. Along the X direction, the end of the fourth sub-frame 3501 facing away from the fifth sub-frame 3502 protrudes beyond the edge of the second middle plate 340, and the end of the sixth sub-frame 3503 facing away from the fifth sub-frame 3502 both protrude beyond the edge of the second middle plate 340, thereby forming a second mounting opening 360 on one side of the second middle plate 320. The second mounting opening 360 is located on the side of the second middle plate 340 facing away from the fifth sub-frame 3502. The second connecting ear 370 is located in the second installation opening 360 .

[0087] The second cover plate 310 is stacked with the second middle frame 320 along the Z direction and is fixedly connected to the second middle frame 320. The second cover plate 310 completely covers the second middle plate 340 and the second mounting opening 360 in the Z direction. In other words, the orthographic projection of the second mounting opening 360 along the Z direction is completely located within the second cover plate 310.

[0088] The second support block 330 is fixed to the inner surface of the second cover plate 310. That is, the second support block 330 is fixed to the surface of the second cover plate 310 facing the second middle plate 340. The second support block 330 faces the second mounting opening 360, and its projection along the Z direction is completely located within the second mounting opening 360. The second support block 330 includes a second support surface 3301. The second support surface 3301 faces the second mounting opening 360. The second support surface 3301 is a convex, curved surface, and the angle between the second support surface 3301 and the X-direction is greater than 0 degrees and less than 90 degrees. Along the positive X-axis, the second support surface 3301 is inclined toward the negative Z-axis. Furthermore, along the positive X-axis, the inclination angle of the second support surface 3301 gradually decreases. Specifically, the angle between the tangent of the second support surface 3301 and the X-direction gradually decreases, and the curvature of the second support surface 3301 decreases. It can be understood that, along the positive direction of the X-axis, the distance from the second supporting surface 3301 to the second cover plate 310 gradually increases.

[0089] See also Figure 7 and Figure 8 , Figure 7 yes Figure 4 The schematic diagram of a part of the structure of the rotating mechanism 100 in the foldable electronic device 1000 is shown. Figure 8 yes Figure 7 FIG. 1 is a schematic diagram of a partially exploded structure of the rotating mechanism 100 .

[0090] The rotating mechanism 100 includes a rotating component 1 and a door panel assembly 10. The rotating component 1 includes a base 20, a first rotating portion 101, and a second rotating portion 102. The first rotating portion 101 and the second rotating portion 102 are mounted on opposite sides of the base 20 along the X direction and are rotatably connected to the base 20. The door panel assembly 10 includes a first door panel 11, a second door panel 12, and an intermediate door panel 13. The first door panel 11 and the second door panel 12 are respectively arranged on opposite sides of the intermediate door panel 13 in the X direction. The first door panel 11 is mounted on the first rotating portion 101, the intermediate door panel 13 is mounted on the base 20, and the second door panel 12 is mounted on the second rotating portion 102.

[0091] The first door panel 11 includes a first surface 111 and a second surface 112. Along the thickness direction of the first door panel 11, the first surface 111 and the second surface 112 are arranged opposite to each other, and the second surface 112 faces the first rotating part 101. That is, when the rotating mechanism 100 is in the expanded state, the second surface 112 faces the negative direction of the Z axis, and the first surface 111 faces the positive direction of the Z axis. Among them, the first surface 111 is a concave inclined surface. When the rotating mechanism 100 is in the expanded state, the angle between the first surface 111 and the width direction (X direction) of the base 20 is greater than 0 degrees and less than 90 degrees. Moreover, along the direction from the middle door panel 13 to the first door panel 11, the first surface 111 is inclined toward the bottom direction of the base 20. That is, along the negative direction of the X axis, the first surface 111 is inclined toward the negative direction of the Z axis.

[0092] The second door panel 12 includes a third surface 121 and a fourth surface 122. The third surface 121 and the fourth surface 122 are arranged relative to each other along the thickness direction of the second door panel 12, and the fourth surface 122 faces the second rotating part 102. That is, when the rotating mechanism 100 is in the expanded state, the fourth surface 122 faces the negative direction of the Z axis, and the third surface 121 faces the positive direction of the Z axis. Among them, the third surface 121 is a concave inclined surface. When the rotating mechanism 100 is in the expanded state, the angle between the third surface 121 and the width direction (X direction) of the base 20 is greater than 0 degrees and less than 90 degrees. In addition, along the direction from the middle door panel 13 to the second door panel 12, the third surface 121 is inclined toward the bottom direction of the base 20. That is, along the positive direction of the X axis, the third surface 121 is inclined toward the negative direction of the Z axis.

[0093] The first rotating portion 101 is connected to the first housing 200, with the end of the first door panel 11 away from the middle door panel 13 located within the first housing 200. The second rotating portion 102 is connected to the second housing 300, with the end of the second door panel 12 away from the middle door panel 13 located within the second housing 300. The display screen is located on the side of the base 20 facing away from the middle door panel 13, that is, on the negative axial side of the base 20.

[0094] When the first housing 200 rotates relative to the base 20, it drives the first rotating portion 101 to rotate relative to the base 20, thereby driving the first door panel 11 to rotate relative to the base 20. When the second housing 300 rotates relative to the base 20, it drives the second rotating portion 102 to rotate relative to the base 20, thereby driving the second door panel 12 to rotate relative to the base 20.

[0095] In this embodiment, by setting the first surface 111 of the first door panel 11 as a concave slope, and when the rotating mechanism 100 is in the expanded state, the first surface 111 is inclined toward the bottom direction of the base 20 along the direction from the middle door panel 13 to the first door panel 11, the distance from the end of the first door panel 11 close to the middle door panel 13 to the back side of the first shell 200 (the surface facing away from the display screen 400) can be reduced in the thickness direction of the rotating mechanism 100, that is, the distance between the base 20 and the back side of the first shell 200 is reduced. Moreover, in this embodiment, by setting the third surface 121 of the second door panel 12 as a concave slope, and when the rotating mechanism 100 is in the unfolded state, the third surface 121 is inclined toward the bottom direction of the base 20 along the direction from the middle door panel 13 to the second door panel 12, the distance from the end of the second door panel 12 close to the middle door panel 13 to the back side of the second shell 300 (the surface facing away from the display screen 400) can be reduced in the thickness direction of the rotating mechanism 100, that is, the distance between the base 20 and the back side of the second shell 300 is reduced, thereby making the foldable electronic device 1000 more compact in the thickness direction, and further reducing the thickness of the foldable electronic device 1000, which is conducive to achieving the lightweight and thinness of the foldable electronic device 1000.

[0096] See also Figure 9 , Figure 9 yes Figure 8 Schematic diagram of the partial exploded structure of the rotating mechanism shown.

[0097] The rotating component 1 includes a base 20, a swing arm assembly 2 and a fixing frame 50. The swing arm assembly 2 includes a first swing arm assembly 30 and a second swing arm assembly 40. The first swing arm assembly 30 includes a first main swing arm 31, a first door panel swing arm 32 and a first auxiliary swing arm 33. The first main swing arm 31, the first door panel swing arm 32 and the first auxiliary swing arm 33 are arranged in sequence along the Y direction. The first main swing arm 31, the first door panel swing arm 32 and the first auxiliary swing arm 33 are installed in the positive direction of the X axis of the base 20 and are rotatably connected to the base 20. The second swing arm assembly 40 includes a second main swing arm 41, a second door panel swing arm 42 and a second auxiliary swing arm 43 arranged in sequence in the Y direction. The second main swing arm 41, the second door panel swing arm 42 and the second auxiliary swing arm 43 are installed in the negative direction of the X axis of the base 20 and are connected to the base 20.

[0098] The fixing frame 50 includes a first fixing frame 51 and a second fixing frame 52. The first fixing frame 51 is located on the positive side of the base 20 in the X-axis direction and is connected to the end of the first swing arm assembly 30 away from the base 20. The second fixing frame 52 is located on the negative side of the base 20 in the X-axis direction and is connected to the end of the second swing arm assembly 40 away from the base 20.

[0099] At the same time, the first fixing frame 51 is fixedly connected to the first shell 200, and the second fixing frame 52 is fixedly connected to the second shell 300.

A bolt is provided in the second connecting ear 370 of the second housing 300, and the bolt provided in the second connecting ear 370 is fixedly connected to the second connecting ear 370 and the second fixing bracket 52.

[0100] When the first shell 200 and the second shell 300 rotate relative to each other, the first shell 200 drives the first fixing frame 51 to rotate relative to the base 20, thereby driving the first main swing arm 31, the first door panel swing arm 32 and the first auxiliary swing arm 33 to rotate relative to the base 20 at the same time; the second shell 300 drives the second fixing frame 52 to rotate relative to the base 20, thereby driving the second main swing arm 41, the second door panel swing arm 42 and the second auxiliary swing arm 43 to rotate relative to the base 20 at the same time, thereby realizing the rotation of the rotating component 1 and the rotating mechanism 100, so that the rotating component 1 can be unfolded or folded.

[0101] It should be noted that Figure 7 、 Figure 8 and Figure 9 Only the partial structure of the rotating component 1 in the positive direction of the Y axis is shown. Figure 9 The fixing frame 50 and the swing arm assembly 2 are a group of substructures. The entire rotating mechanism 100 can have one or more groups of the above-mentioned substructures. "Multiple groups" refers to two or more groups. When the rotating mechanism 100 has two groups of the above-mentioned substructures, the two groups of substructures are arranged on the base 20 at intervals along the Y direction, and the two groups of substructures are symmetrically arranged along the center line of the base 20 in the Y direction. In order to enhance the stability of the entire rotating component 1, a group of the above-mentioned substructures is further provided between the substructures at both ends of the base 20, and the substructure is located in the middle of the base 20. In order to further enhance the stability of the entire rotating component 1, two groups of the above-mentioned substructures can also be directly added to the substructures at both ends of the base 20. The number of the above-mentioned substructures can be adjusted according to actual conditions.

[0102] The first fixing frames 51 of the multiple substructures can be split, i.e., separate components that are not fixed to each other. Alternatively, the first fixing frames 51 of the multiple substructures can be fixedly connected to each other, or can be an integrally formed structure. The second fixing frames 52 of the multiple substructures can be split, fixedly connected to each other, or can be an integrally formed structure.

[0103] In other embodiments, the rotation mechanism 100 may further include a synchronization component and a damping component. The synchronization component is mounted on the base 20 and connected to the fixing bracket 50. The synchronization component is used to achieve synchronized rotation of the structures on opposite sides of the base 20 in the X-direction. The damping component is mounted on the base 20 and fixedly connected thereto. The damping component is used to provide a damping force for the rotation of the rotating component 1, thereby providing a damping feel to the user.

[0130] The first sliding body 331 of the first auxiliary swing arm 33 is mounted in the first guide slot 513 and is slidable along the first guide slot 513. The third shaft seat 332 is rotatably connected to the first shaft seat 25 of the base 20. For example, a rotation shaft is provided within the first shaft seat 25 and the third shaft seat 332. The rotation shaft is fixedly connected to the first shaft seat 25 and is rotatably connected to the third shaft seat 332.

[0131] When the first fixed frame 51 rotates relative to the base 20, it drives the first fixed block 311 to rotate relative to the base 20, thereby driving the first rotating block 312 to rotate relative to the base 20, and causing the second arc block 3122 to slide along the first rotating groove 21, and the first arc block 3121 to slide along the first arc groove 3111; at the same time, the first fixed frame 51 also drives the first swinging body 322 to rotate relative to the base 20, thereby driving the first rotating body 321 to slide along the third rotating groove 23, and causing the first shaft body 323 to slide along the first sliding groove 3112; and the first fixed frame 51 also drives the first sliding body 331 to rotate relative to the base 20, and causes the third shaft seat 332 to rotate around the rotating axis provided on the first shaft seat 25, and the first sliding body 331 slides along the first guide groove 513.

[0132] The second fixed frame 52 and the second swing arm assembly 40 are mounted in the negative direction of the X-axis of the base 20. The second fixed frame 52 is symmetrically arranged with the first fixed frame 51, and the second swing arm assembly 40 is symmetrically arranged with the first swing arm assembly 30. The second main swing arm 41, the second door panel swing arm 42, and the second auxiliary swing arm 43 are arranged in sequence along the Y-direction. Among them, the third arc block 4121 is mounted in the second arc groove of the second fixed block 411 and can slide along the second arc groove. The fourth arc block 4122 is mounted in the second rotation groove 22 of the base 20 and can slide along the second rotation groove 22. The second fixed block 411 is mounted in the third mounting portion 521 of the second fixed frame 52 and is fixedly connected to the second fixed frame 52.

[0133] The second swinging body 422 of the second door panel swing arm 42 is installed in the fourth mounting portion 522 of the second fixed frame 52 and is fixedly connected to the second fixed frame 52. The second rotating body 421 is installed in the third rotating groove 23 and can slide along the third rotating groove 23. The second shaft 423 is slidably connected to the second main swing arm 41. Exemplarily, the second fixed block 411 is provided with a second sliding groove. The opening of the second sliding groove faces the second door panel swing arm 42, and the extension direction of the second sliding groove is parallel to the X direction. The second shaft 423 is installed in the second sliding groove and can slide along the second sliding groove.

[0134] The second sliding body 431 of the second auxiliary swing arm 43 is mounted in the second guide slot 523 and can slide along the second guide slot 523. The fourth shaft seat 432 is rotatably connected to the second shaft seat 26 of the base 20. For example, a rotation shaft is provided in the second shaft seat 26 and the fourth shaft seat 432. The rotation shaft is fixedly connected to the second shaft seat 26 and rotatably connected to the fourth shaft seat 432.

[0135] When the second fixed frame 52 rotates relative to the base 20, it drives the second fixed block 411 to rotate relative to the base 20, thereby driving the second rotating block 412 to rotate relative to the base 20, and causing the fourth arc block 4122 to slide along the second rotating groove 22, and the third arc block 4121 to slide along the second arc groove; at the same time, the second fixed frame 52 also drives the second swinging body 422 to rotate relative to the base 20, thereby driving the second rotating body 421 to slide along the fourth rotating groove 24, and causing the second shaft body 423 to slide along the second sliding groove; and the second fixed frame 52 also drives the second sliding body 431 to rotate relative to the base 20, and causes the fourth shaft seat 432 to rotate around the rotating axis provided on the second shaft seat 26, and the second sliding body 431 slides along the second guide groove 523.

[0136] The rotation direction of the first fixing frame 51 is opposite to that of the second fixing frame 52, and the rotation direction of the first swing arm assembly 30 is opposite to that of the second swing arm assembly 40. For example, when the rotating mechanism 100 rotates from the deployed state to the folded state, the first fixing frame 51 and the first swing arm assembly 30 rotate clockwise, while the second fixing frame 52 and the second swing arm assembly 40 rotate counterclockwise. When the rotating mechanism 100 rotates from the folded state to the deployed state, the first fixing frame 51 and the first swing arm assembly 30 rotate counterclockwise, while the second fixing frame 52 and the second swing arm assembly 40 rotate clockwise.

[0137] See also Figure 15 and Figure 16 , Figure 15 yes Figure 8 The schematic diagram of the partially exploded structure of the door panel assembly 10 in the rotating mechanism 100 is shown. Figure 16 yes Figure 15 The structure diagram of the door panel assembly 10 shown is from another angle.

[0138] The middle door panel 13 is a long strip-shaped plate-like structure. The middle door panel 13 is provided with a first protrusion 131 and a second protrusion 134 on opposite sides along the X direction. The outer surface of the first protrusion 131 includes a first inclined surface 132 and a first connecting surface 133. The first inclined surface 132 intersects with the X direction, and the angle between the first inclined surface 132 and the X direction is greater than 0 degrees and less than 90 degrees. One end of the first inclined surface 132 is connected to the top surface of the middle door panel 13 (the surface facing the positive direction of the Z axis), and the other end is connected to the first connecting surface 133. The first connecting surface 133 is parallel to the Z direction, and the first connecting surface 133 is connected between the first inclined surface 132 and the bottom surface of the middle door panel 13 (the surface facing the negative direction of the Z axis).

[0139] The second protrusion 134 is symmetrically arranged with the first protrusion 131. The outer surface of the second protrusion 134 includes a second inclined surface 135 and a second connecting surface 136. The second inclined surface 135 intersects the X-direction to prevent a gap from forming between the middle door panel 13 and the second door panel 12. One end of the second inclined surface 135 is connected to the top surface of the middle door panel 13, and the other end is connected to the second connecting surface 136. The second connecting surface 136 is parallel to the Z-direction and connects between the second inclined surface 135 and the bottom surface of the middle door panel 13.

[0140] The back of the middle door panel 13 is provided with a connecting column 137. The connecting column is used to be fixedly connected to the base 20. For example, the base 20 is provided with a mounting hole 27 (such as Figure 10), during the actual assembly process, the connecting posts of the middle door panel 13 are first aligned with the mounting holes 27 and mounted on the base 20. Then, a welding machine is used to spot weld the middle door panel 13 and the base 20 to achieve a fixed connection between the middle door panel 13 and the base 20. In other embodiments, the middle door panel 13 and the base can also be fixedly connected by bolts or adhesive.

[0141] In this embodiment, the first door panel 11 is an elongated, plate-like structure, and the cross-section of the first door panel 11 along the XZ plane is approximately trapezoidal. The length of the first door panel 11 is equal to or approximately equal to the length of the base 20. In other words, the dimension of the first door panel 11 along the Y direction is equal to or approximately equal to the dimension of the base 20 along the Y direction.

[0142] The first door panel 11 includes a first surface 111, a second surface 112, a first end surface 113, and a second end surface 114. The first surface 111 and the second surface 112 are arranged opposite each other in the thickness direction (Z direction) of the first door panel 11. The first end surface 113 and the second end surface 114 are arranged opposite each other in the width direction (X direction) of the first door panel 11 and are both connected between the first surface 111 and the second surface 112. The second end surface 114 is an inclined surface. That is, the second end surface 114 is parallel to the X direction. In this embodiment, the second end surface 114 is parallel to the first inclined surface 132 of the middle door panel 13. When the first door panel 11 is arranged on the negative side of the X axis of the middle door panel 13, the second end surface 114 faces the first protrusion 131. The orthographic projection of the second end surface 114 along the Z direction is flush with the outer surface of the first protrusion 131, or there may be a small gap (within the tolerance range). Alternatively, the orthographic projection of the second end surface 114 along the Z direction at least partially overlaps with the first protrusion 131. In this way, the gap between the middle door panel 13 and the first door panel 11 along the X direction can be reduced or avoided, thereby improving the refinement of the appearance of the foldable electronic device 1000.

[0143] The second surface 112 is a plane, and the second surface 112 is parallel or approximately parallel to the XY plane. The first surface 111 includes a first end 115 and a second end 116. The first end 115 and the second end 116 are arranged opposite each other along the X direction. The first surface 111 is a concave inclined surface and a curved surface, and the angle between the first surface 111 and the X direction is greater than 0 degrees and less than 90 degrees. In this embodiment, the structure of the first surface 111 is compatible with the structure of the first support surface 2301. "Compatible" here means that the curvature of the first surface 111 is the same or approximately the same as the curvature of the first support surface 2301, that is, the contour of the first surface 111 is approximately the same as the contour of the first support surface 2301. When the first surface 111 and the first support surface 2301 are arranged opposite each other, the first surface 111 is parallel to the first support surface 2301. Specifically, the first surface 111 is curved toward the second surface 112. Along the negative X-axis direction, that is, from the second end 116 to the first end 115, the first surface 111 is inclined toward the negative Z-axis direction. In addition, the height between the first end 115 and the second end 116 along the Z-direction is 0.3 mm to 0.6 mm.

[0144] Here, a "concave slope" refers to a slope that is steep at the top and gentle at the bottom. That is, the inclination angle of first surface 111 gradually decreases from second end 116 to first end 115. In other words, the angle between the tangent of first surface 111 and the X-direction gradually decreases, and the curvature of first surface 111 gradually decreases. It is understood that first end 115 is located on the negative Z-axis side of second end 116.

[0145] Please also refer to Figure 17 and Figure 18 , Figure 17 yes Figure 15 The partially exploded structural diagram of the door panel assembly 10 is shown. Figure 18 yes Figure 16 The door panel assembly 10 is shown as a partial structural schematic diagram at another angle.

[0146] The door panel assembly 10 also includes a first stud block 14 and a first slider 15. The first stud block 14 is fixed to the back of the first door panel 11 and is used to be fixedly connected to the first door panel swing arm 32 in the first swing arm assembly 30. In this embodiment, the first stud block 14 is fixedly connected to the first door panel 11 and the first door panel swing arm 32 by welding. In other embodiments, the first stud block 14 and the first door panel 11 can also be fixedly connected by bolting, bonding or other means. The first stud block 14 and the first door panel swing arm 32 can also be fixedly connected by bolting, bonding or other means.

[0147] Among them, the first stud block 14 can be one or more. When there are multiple first stud blocks 14, the multiple first stud blocks 14 are fixed to the first door panel 11 at intervals along the Y direction. In this embodiment, there are three first stud blocks 14. The three first stud blocks 14 are arranged on the first door panel 11 at intervals along the Y direction. The first first stud block 14 is arranged at an end of the first door panel 11 close to the positive direction of the Y axis, the second first stud block 14 is arranged at an end of the first door panel 11 close to the negative direction of the Y axis, and the third first stud block 14 is arranged in the middle of the first door panel 11 along the Y direction. In other embodiments, there can also be three, four or more first stud blocks 14, and there is no specific restriction on the number of first stud blocks 14 here.

[0148] The first slider 15 includes a first body 151 and a first slide post 152. The first body 151 is in the shape of a thin plate. The first slide post 152 is cylindrical. The first slide post 152 is fixedly connected to the first body 151, and the extension direction of the first slide post 152 is parallel to the X direction. The first body 151 is fixed to the back of the first door panel 11 and is spaced apart from the first stud block 14. The first slide post 152 is used for sliding connection with the first fixing frame 51. In this embodiment, the first door panel 11 and the first body 151 are fixedly connected by welding. For example, a positioning post 153 is provided on the back of the first door panel 11, and the first body 151 is provided with a positioning hole 119 corresponding to the positioning post 153. During the actual assembly process, the positioning hole 119 of the first slider 15 is first aligned with the positioning post 153 and installed on the first door panel 11, and then spot welding is performed using a welding machine to weld the first slider 15 to the first door panel 11. In other embodiments, the first body 151 may also be fixedly connected to the first door panel 11 by bolt connection, bonding or other methods.

[0149] There are one or more first sliders 15. When there are multiple first sliders 15, the multiple first sliders 15 are fixed to the first door panel 11 in sequence along the Y direction, and are spaced apart from the first stud block 14. In this embodiment, there are two first sliders 15. The two first sliders 15 are spaced apart on the first door panel 11 along the Y direction. One of the first sliders 15 is provided at the end of the first door panel 11 close to the positive direction of the Y axis, and the other first slider 15 is provided at the end of the first door panel 11 close to the negative direction of the Y axis. In this embodiment, by evenly arranging the three first sliders 15 on the first door panel 11, the force on the first door panel 11 can be evenly distributed, and the connection stability between the first door panel 11 and the first fixing frame 51 can also be improved. In other embodiments, there can also be two, four or more first sliders 15, and there is no specific restriction on the number of first sliders 15 here.

[0150] Please continue reading Figure 16The second door panel 12 and the first door panel 11 are mirror-symmetrical structures. The second door panel 12 includes a third surface 121, a fourth surface 122, a third end face 123 and a fourth end face 124. The third surface 121 and the fourth surface 122 are arranged opposite to each other in the Z direction. The third end face 123 and the fourth end face 124 are arranged opposite to each other along the X direction, and are both connected between the third surface 121 and the fourth surface 122. Among them, the fourth end face 124 is a bevel. In this embodiment, the fourth end face 124 is parallel to the second bevel 135 of the middle door panel 13. When the second door panel 12 is arranged on the positive direction side of the X axis of the middle door panel 13, the fourth end face 124 faces the second protrusion 134. The orthographic projection of the fourth end face 124 along the Z direction is flush with the outer surface of the second protrusion 134, or has a small gap (within the tolerance range). Alternatively, the orthographic projection of the fourth end face 124 along the Z direction at least partially overlaps with the second protrusion 134. This can reduce or avoid the gap between the middle door panel 13 and the second door panel 12 along the X direction, further improving the refinement of the appearance of the foldable electronic device 1000.

[0151] The fourth surface 122 is a planar surface, parallel or substantially parallel to the XY plane. The third surface 121 includes a third end 125 and a fourth end 126. The third end 125 and the fourth end 126 are arranged opposite each other along the X-direction. The third surface 121 is a concave, inclined surface and an arcuate surface, and the angle between the first surface 111 and the X-direction is greater than 0 degrees and less than 90 degrees. In this embodiment, the structure of the third surface 121 is compatible with the structure of the second support surface 3301. "Compatible" here means that the curvature of the third surface 121 is the same or substantially the same as the curvature of the second support surface 3301, that is, the contour of the third surface 121 is substantially the same as the contour of the second support surface 3301. When the third surface 121 and the second support surface 3301 are arranged opposite each other, the third surface 121 and the second support surface 3301 are parallel and in contact with each other. Specifically, the third surface 121 curves toward the fourth surface 122. Along the direction from the fourth end 126 to the third end 125, the third surface 121 is inclined toward the negative Z-axis direction. The height between the third end 125 and the fourth end 126 along the Z-direction is 0.3 mm to 0.6 mm. In this embodiment, the inclination angle gradually decreases along the direction from the fourth end 126 to the third end 125. In other words, the angle between the tangent of the third surface 121 and the X-direction gradually decreases, that is, the curvature of the third surface 121 gradually decreases. It can be understood that the third end 125 is located on the negative Z-axis side of the fourth end 126.

[0152] Please combine Figure 18, the door panel assembly 10 also includes a second stud block 16 and a second slider 17. The structure of the second stud block 16 is the same as or substantially the same as that of the first stud block 14. The first stud block 14 is fixed to the back of the second door panel 12 and is fixedly connected to the second rotating part 102. The structure of the second slider 17 is the same as or substantially the same as that of the first slider 15. The second slider 17 includes a second body 171 and a second slide 172. The second slide 172 is fixedly connected to the second body 171, and the extension direction of the second slide 172 is parallel to the X direction. The second body 171 is fixed to the back of the second door panel 12 and is spaced apart from the second stud block 16. The second slide 172 is used for sliding connection with the second rotating part 102.

[0153] Please combine Figure 7 and Figure 19 , Figure 19 yes Figure 7 FIG. 1 is a schematic diagram of a partially enlarged structure of the rotating mechanism 100 .

[0154] The first door panel 11, the middle door panel 13, and the second door panel 12 are arranged in sequence along the X-axis, with the first door panel 11 located on the negative side of the middle door panel 13 in the X-axis direction, and the second door panel 12 located on the positive side of the middle door panel 13 in the X-axis direction. The door panel assembly 10 is mounted on the front of the rotating component 1. The middle door panel 13 is mounted on the base 20, with the back of the middle door panel 13 facing the top surface 201 of the base 20. The connecting column 137 provided on the back of the middle door panel 13 is fixedly connected to the base 20, thereby achieving a fixed connection between the middle door panel 13 and the base 20. The first door panel 11 is mounted on the first rotating part 101. The first stud block 14 is fixedly connected to the first door panel swing arm 32. The first slide column 152 of the first slider 15 is mounted in the first slide groove 515 of the first fixing frame 51, and the first slide column 152 can slide along the first slide groove 515. The second door panel 12 is mounted on the second rotating part 102. The second stud block 16 is fixedly connected to the second door panel swing arm 42. The second slide post 172 of the second slider 17 is installed in the second slide groove 524 of the second fixing frame 52, and the second slide post 172 can slide along the second slide groove 524.

[0155] Please also refer to Figure 20 , Figure 20 yes Figure 3 A partial cross-sectional structural diagram of a foldable electronic device 1000 is shown.

[0156] The rotating mechanism 100 is installed between the first shell 200 and the second shell 300, and the first fixing frame 51 is connected to the first connecting ear 260 (such as Figure 5The first door panel 11 is fixedly connected to the second housing 300 (as shown). The end of the first door panel 11 away from the base 20 is located in the first mounting opening 260 and is positioned adjacent to the first support block 230. The second fixing bracket 52 is fixedly connected to the second housing 300. The end of the second door panel 12 away from the base 20 is located in the second mounting opening 360 and is positioned adjacent to the second support block 330.

[0157] like Figure 20 As shown, when the foldable electronic device 1000 is in the unfolded state, the first housing 200 and the second housing 300 are unfolded relative to each other, the first rotating portion 101 and the second rotating portion 102 are unfolded relative to each other, and the first door panel 11 and the second door panel 12 are unfolded relative to each other. In other words, the angle between the first housing 200 and the second housing 300 is approximately 180 degrees, and the angle between the first rotating portion 101 and the second rotating portion 102 is approximately 180 degrees.

[0158] At this point, the door panel assembly 10 is located outside the foldable electronic device 1000, meaning that the user can directly see the door panel assembly 10. In this embodiment, by placing the door panel assembly 10 on the top of the rotating component 1 (the side facing the positive Z-axis), it serves as a decoration for the foldable electronic device 1000, preventing the user from directly observing the internal structure of the rotating component 1, thereby improving the aesthetics of the foldable electronic device 1000. Furthermore, the door panel assembly 10 also protects the internal structure of the rotating component 1, extending the service life of the rotating mechanism 100.

[0159] The first door panel 11 and the first support block 230 are arranged along the X-direction and are located in the positive X-axis direction of the first support block 230. The first end 115 of the first door panel 11 is located in the first mounting opening 260 and is spaced apart from the first cover plate 210 in the Z-direction. The second end 116 is located outside the first housing 200 and is flush with the middle door panel 13 in the X-direction. Furthermore, the second end 116 is located in the positive Z-axis direction of the first end 115 and in the negative Z-axis direction of the outer surface of the first cover plate 210. The minimum distance between the first door panel 11 and the outer surface of the first cover plate 210 in the Z-direction is H1. That is, the distance between the second end 116 and the outer surface of the first cover plate 210 in the Z-direction is H1. That is, the distance between the top of the rotating mechanism 100 (the side facing the positive Z-axis direction) and the outer surface of the first cover plate 210 is H1. Here, H1 is 0-0.1 mm. Alternatively, H1 can be slightly larger than 0.1 mm.

[0160] The second door panel 12 and the second support block 330 are arranged along the X direction and are located in the negative X direction of the second support block 330. The third end 125 of the second door panel 12 is located in the second mounting opening 360 and is spaced apart from the second cover plate 310 along the Z direction. The fourth end 126 is located in the positive Z direction of the third end 125 and in the negative Z direction of the outer surface of the second cover plate 310. The minimum distance from the second door panel 12 to the outer surface of the second cover plate 310 along the Z direction is H1'. That is, the distance from the fourth end 126 to the outer surface of the second cover plate 310 along the Z direction is H1'. Here, H1' is 0-0.1mm. Alternatively, H1' may be slightly larger than 0.1mm.

[0161] See also Figure 21 , Figure 21 yes Figure 20 The diagram shows a partial structure of the foldable electronic device 1000 in a folded state.

[0162] When the foldable electronic device 1000 rotates from the unfolded state to the folded state, the first shell 200 and the second shell 300 rotate toward each other, that is, the first shell 200 rotates in a clockwise direction and the second shell 300 rotates in a counterclockwise direction.

[0163] When the first housing 200 rotates clockwise, it drives the first fixing bracket 51 to rotate clockwise, thereby driving the first door panel swing arm 32 to rotate clockwise. When the first door panel swing arm 32 rotates clockwise, it drives the first door panel 11 to rotate clockwise. Simultaneously, the first slide post 152 slides along the first slide slot 515 toward the end away from the base 20, driving the first door panel 11 away from the middle door panel 13, that is, toward the first housing 200. At this point, the first door panel 11 moves relative to the first housing 200 toward the first support block 230, and the first surface 111 slides along the first support surface 2301.

[0164] When the second housing 300 rotates counterclockwise, it drives the second fixing bracket 52 to rotate counterclockwise, thereby driving the second door panel swing arm 42 to rotate counterclockwise. When the second door panel swing arm 42 rotates counterclockwise, it drives the second door panel 12 to rotate counterclockwise. Simultaneously, the second slide post 172 slides along the second slide slot 524 toward the end away from the base 20, driving the second door panel 12 away from the middle door panel 13, that is, toward the second housing 300. At this point, the second door panel 12 moves relative to the second housing 300 toward the second support block 330, and the third surface 121 slides along the second support surface 3301.

[0165] In this embodiment, by connecting the first door panel 11 to the first rotating portion 101 and driving the first door panel 11 to rotate through the rotation of the first fixing frame 51 and the first door panel swing arm 32, the stability of the rotation of the first door panel 11 can be improved. At the same time, in this embodiment, by fixing the first sliding column 152 to the first door panel 11 and providing the first sliding groove 515 on the first fixing frame 51, a sliding connection between the first door panel 11 and the first fixing frame 51 can be achieved, so that when the rotating mechanism 100 rotates from the unfolded state to the folded state, the first door panel 11 can move in a direction away from the middle door panel 13, thereby avoiding interference between the first door panel 11 and the middle door panel 13, and improving the smoothness and stability of the rotation of the rotating mechanism 100.

[0166] Furthermore, in this embodiment, by connecting the second door panel 12 to the second rotating portion 102 and driving the second door panel 12 to rotate through the rotation of the second fixing frame 52 and the second door panel swing arm 42, the stability of the rotation of the second door panel 12 can be improved. At the same time, in this embodiment, by fixing the second sliding post 172 to the second door panel 12 and providing the second sliding groove 524 on the second fixing frame 52, a sliding connection between the second door panel 12 and the second fixing frame 52 can be achieved. When the rotating mechanism 100 rotates from the unfolded state to the folded state, the second door panel 12 can move in a direction away from the middle door panel 13, thereby avoiding interference between the second door panel 12 and the middle door panel 13, and further improving the smoothness and stability of the rotation of the rotating mechanism 100.

[0167] like Figure 21 As shown, when the foldable electronic device 1000 is in the folded state, the first shell 200 and the second shell 300 are arranged opposite to each other and approximately in parallel, and the first door panel 11 and the second door panel 12 are arranged opposite to each other.

[0168] The first door panel 11 and the first support block 230 are stacked along the thickness direction of the first housing 200, with the first surface 111 facing and contacting the first support surface 2301. The second door panel 12 and the second support block 330 are stacked along the thickness direction of the second housing 300, with the third surface 121 facing and contacting the second support surface 3301.

[0169] In this embodiment, by setting the first support block 230 on the inner surface of the first cover plate 210, and when the foldable electronic device 1000 is in a folded state, the first support block 230 is arranged opposite to the first door panel 11, so that the first support block 230 supports the first door panel 11, which can prevent the first cover plate 210 from scratching the first door panel 11 and affecting the appearance of the first door panel 11. At the same time, it can also reduce the pressure of the first door panel 11 on the first cover plate 210, thereby avoiding the formation of mold marks on the first cover plate 210 and improving the sophistication of the foldable electronic device 1000.

[0170] In this embodiment, by setting the first surface 111 of the first door panel 11 and the first supporting surface 2301 of the first supporting block 230 as concave inclined surfaces, when the foldable electronic device 1000 rotates, the rotation angle of the first door panel 11 relative to the first shell 200 is more adapted. At the same time, it can also provide a tolerance space for the rotation of the first door panel 11 to avoid interference between the first door panel 11 and the first shell 200, thereby improving the smoothness and stability of the rotation of the rotating mechanism 100 and the foldable electronic device 1000.

[0171] Furthermore, in this embodiment, by configuring the structure of the first surface 111 to match the structure of the first support surface 2301, the first surface 111 of the first door panel 11 can move along the first support surface 2301 of the first support block 230 to face the first support block 230 during the rotation of the foldable electronic device 1000 from the unfolded state to the folded state. This improves the smoothness and stability of the movement of the first door panel 11 relative to the first support block 230, thereby improving the smoothness of the rotation of the foldable electronic device 1000. Furthermore, in this embodiment, by configuring the first support surface 2301 as a convex inclined surface and the first surface 111 as a concave inclined surface, the first surface 111 can fully contact the first support surface 2301 when the foldable electronic device 1000 is in the folded state. This increases the contact area between the first door panel 11 and the first support block 230, thereby improving the support stability of the first support block 230 on the first door panel 11 and the stability of the connection between the first door panel 11 and the first housing 200.

[0172] At the same time, in this embodiment, by setting the first surface 111 of the first door panel 11 as a concave slope, and when the foldable electronic device 1000 is in the unfolded state, the first end 115 is located on the positive direction of the Z axis of the second end 116, the minimum distance between the first door panel 11 and the outer surface of the first cover plate 210 along the Z direction can be reduced, that is, the distance between the top of the rotating mechanism 100 and the outer surface of the first cover plate 210 is reduced, so that the foldable electronic device 1000 is more compact in the Z direction, thereby reducing the size of the foldable electronic device 1000 along the Z direction, that is, the thickness of the foldable electronic device 1000 can be reduced, and the weight of the foldable electronic device 1000 can be reduced, which is conducive to realizing the lightweight and thinness of the foldable electronic device 1000 and improving the user's feel.

[0173] Similarly, in this embodiment, by setting a second support block 330 on the inner surface of the second cover plate 310, the pressure of the second door panel 12 on the second cover plate 310 can be reduced, thereby avoiding the generation of embossing on the second cover plate 310; by setting the third surface 121 of the second door panel 12 as a concave inclined surface matching the structure of the second support surface 3301, the smoothness of the movement of the second door panel 12 relative to the second support block 330 can be improved. At the same time, the contact area between the second door panel 12 and the second support block 330 can also be increased, thereby improving the support stability of the second support block 330 on the second door panel 12 and the connection stability between the second door panel 12 and the second shell 300; by setting the third surface 121 of the second door panel 12 as a concave inclined surface, and the third end 125 is located on the positive direction side of the Z axis of the fourth end 126, the minimum distance between the second door panel 12 and the outer surface of the second cover plate 310 along the Z direction can be reduced, thereby reducing the thickness of the foldable electronic device 1000.

[0174] Moreover, in the foldable electronic device 1000 provided in this embodiment, the distance from the top of the rotating mechanism 100 to the outer surface of the first cover plate 210 and to the outer surface of the second cover plate 310 is smaller, so that the outer surface of the foldable electronic device 1000 is more flat.

[0175] When the thickness of the foldable electronic device 1000 is consistent, in the foldable electronic device 1000 provided in this embodiment, the distance from the top of the rotating mechanism 100 to the outer surface of the first cover plate 210 and the second cover plate 310 is smaller, and the size of the rotating mechanism 100 along the Z direction is large, that is, the thickness of the rotating mechanism 100 is larger, so that the thickness of the rotating part 1 can be increased, that is, the size of the swing arm assembly 2 and the base 20 along the Z direction is increased, especially the thickness of the axis area of ​​the rotating mechanism 100 is increased, thereby improving the structural strength, rotational stability and reliability of the rotating mechanism 100, and improving the structural strength and rotational stability of the foldable electronic device 100.

[0176] To further understand this embodiment, please refer to Figure 22 and Figure 23 , Figure 22 is a partial structural diagram of the electronic device 1000a in the unfolded state according to the comparative embodiment. Figure 23 yes Figure 22 The diagram shows a partial structure of the electronic device 1000a in a folded state.

[0177] Figure 22 The comparative example shown is Figure 20 The embodiment shown differs in that Figure 22In the comparative embodiment shown, the first door panel 11a is a planar plate-shaped structure, the first surface 111a and the second surface 112a of the first door panel 11a are both planes, and the first surface 111a and the second surface 112a are arranged in parallel.

[0178] like Figure 22 As shown, when the foldable electronic device 1000a is in the unfolded state, the first door panel 11a is parallel to the XY direction, and the first surface 111a and the second surface 112a are parallel to the XY plane. The minimum distance between the first door panel 11a and the outer surface of the first cover plate 210a along the Z direction is H2. In other words, the distance between the first surface 111a and the outer surface of the first cover plate 210a along the Z direction is H2. In other words, the distance between the top of the rotating mechanism 100a and the outer surface of the first cover plate 210a is H2.

[0179] Combine Figure 20 and Figure 22 ,when Figure 20 The first end 115 of the first door panel 11 is connected to the Figure 22 When the first end 115a of the first door panel 11a is at the same height in the Z direction, that is, the distance between the first end 115a and the first cover panel 210 is equal, Figure 20 The distance between the first end 115 and the outer surface of the first cover plate 210 is Figure 14 The distances between the first end 115a and the outer surface of the first cover plate 210a are equal.

[0180] exist Figure 20 In the illustrated embodiment, H1 is the distance between the second end 116 and the outer surface of the first cover plate 210 , and the second end 116 is located on the positive Z-axis side of the first end 115 . Therefore, H1 is smaller than the distance between the first end 115 and the outer surface of the first cover plate 210 .

[0181] exist Figure 22 In the comparative embodiment shown, the first surface 111a is parallel to the XY plane, the first end 115a and the second end 116a are arranged parallel to each other along the X direction, and the distance between the first end 115a and the outer surface of the first cover plate 210a is equal to the distance between the second end 116a and the outer surface of the first cover plate 210a, which is also equal to the distance between the first surface 111a and the outer surface of the first cover plate 210a along the Z direction. That is, the distance between the first end 115a and the outer surface of the first cover plate 210a is H2. Therefore, H1 is smaller than H2.

[0182] In this embodiment, the difference between H1 and H2 is 0.3mm to 0.6mm. Alternatively, the difference between H1 and H2 can be 0.3mm to 0.5mm, or the difference between H1 and H2 can be 0.35mm to 0.4mm. Figure 20As shown, the present application can reduce the thickness of the foldable electronic device 1000 when in the unfolded state by setting the first surface 111 of the first door panel 11 as a bevel. When the thickness of the foldable electronic device 1000 is uniform, the present application can increase the thickness of the rotating mechanism 100 by setting the first surface 111 of the first door panel 11 as a bevel, thereby improving the strength of the rotating mechanism 100.

[0183] Figure 20 In the illustrated embodiment, by setting the first surface 111 of the first door panel 11 as a slope, and when the foldable electronic device 1000 is in the unfolded state, the first end 115 is located on the positive direction side of the Z axis of the second end 116, the minimum distance along the Z direction between the first door panel 11 and the outer surface of the first cover plate 210 can be reduced, making the foldable electronic device 1000 more compact in the Z direction, thereby reducing the size of the foldable electronic device 1000 along the Z direction, that is, reducing the thickness of the foldable electronic device 1000, which is conducive to achieving the lightweight and thinness of the foldable electronic device 1000.

[0184] like Figure 23 In the comparative embodiment shown, when the rotating mechanism 100a is in the folded state, the first door panel 11a and the first support block 230a are stacked along the thickness direction of the first housing 200a. The first surface 111a and the first support surface 2301a are opposite and in contact, or have a small gap (within a tolerance range). Specifically, the side of the first surface 111a near the first end 115a is in contact with the first support surface 2301a or has a small gap (within a tolerance range), and the side of the first surface 111a near the second end 116a is spaced apart from the first support surface 2301a. The contact area between the first surface 111a and the first support surface 2301a is small, and the pressure exerted by the first support block 230a on the first door panel 11a is concentrated on the side near the first end 115a, resulting in relatively concentrated stress. The first support block 230a is unable to effectively support the first door panel 11a, and the connection stability between the first door panel 11a and the first housing 200a is poor.

[0185] Combine Figure 21 In the embodiment of the present application, when the rotating mechanism 100 is in the folded state, the first supporting surface 2301 is parallel to and in contact with the first surface 111, thereby increasing the contact area between the first door panel 11 and the first supporting block 230, thereby improving the supporting stability of the first supporting block 230 on the first door panel 11, and the connection stability between the first door panel 11 and the first shell 200.

[0186] And, as Figure 23 As shown, in the comparative embodiment, a first blank area A is formed between the first door panel 11 a and the first supporting block 230 a and the first cover panel 210 a .

[0187] like Figure 21 As shown, in the embodiment of the present application, the first surface 111 of the first door panel 11 is arranged along the first support surface 2301, and along the direction from the first end 115 to the second end 116, the first door panel 11 is inclined toward the first cover panel 210, and the gap between the first door panel 11 and the first cover panel 210 is small. That is, Figure 21 In the illustrated embodiment, by setting the first surface 111 of the first door panel 11 as a slope, the first door panel 11 can make full use of the first blank area A, so that the first door panel 11 and the first cover panel 210 are arranged more compactly, which is beneficial to reducing the thickness of the foldable electronic device 1000 and achieving the lightweight and thinness of the foldable electronic device 1000.

[0188] See also Figure 24 , Figure 24 yes Figure 16 The illustrated diagram is a partial structural diagram of the door panel assembly 10 in the second embodiment.

[0189] This embodiment and Figure 16 The difference between the illustrated embodiment and the illustrated embodiment is that, in this embodiment, the first door panel 11 is a curved panel. The first surface 111 and the second surface 112 are curved surfaces, and the curvature of the second surface 112 is the same or substantially the same as the curvature of the first surface 111. In this embodiment, by configuring the first door panel 11 as a curved panel, the shape of the first surface 111 is ensured to be compatible with the first support surface 2301, while also reducing the weight of the first door panel 11, thereby reducing the weight of the foldable electronic device 1000.

[0190] The second door panel 12 is a curved panel. The curvature of the third surface 121 and the fourth surface 122 is the same or substantially the same as the curvature of the third surface 121. In this embodiment, by configuring the second door panel 12 as a curved panel, the weight of the first door panel 11 can be reduced, thereby further reducing the weight of the foldable electronic device 1000.

[0191] See also Figure 25 , Figure 25 yes Figure 9 The illustrated diagram is a partial structural diagram of the door panel assembly 10 in the third embodiment.

[0192] This embodiment and Figure 24 The difference of the embodiment shown is that the first door panel 11 includes a first curved plate 117 and a first reinforcement 118. The first curved plate 117 is a curved plate, and the structure of the first curved plate 117 is the same as that of the first door panel 111. Figure 24The structure of the first door panel 11 in the illustrated embodiment is identical. The cross-section of the first reinforcement 118 along the XZ plane is approximately triangular. The first reinforcement 118 is secured to the backside of the first curved plate 117. In this embodiment, securing the first reinforcement 118 to the backside of the first curved plate 117 enhances the strength of the first door panel 11.

[0193] The second door panel 12 includes a second curved plate 127 and a second reinforcement 128. The second curved plate 127 is a curved plate, and the structure of the second curved plate 127 is similar to that of the second door panel 128. Figure 9 The second door panel 12 in the illustrated embodiment has the same structure. The second reinforcement 128 is fixed to the back of the second curved plate 127. In this embodiment, by fixing the second reinforcement 128 to the back of the second curved plate 127, the strength of the second door panel 12 can be improved.
