Description

Technical Field

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

[0002] Traditional mobile phones and other foldable electronic devices usually adopt inward folding or outward folding solutions. Inward folding refers to a mobile phone with the display screen on the inside after the mobile phone is folded. Outward folding refers to a mobile phone with the display screen on the outside after the mobile phone is folded. Regardless of whether the mobile phone is folded inward or outward, the rotation range of the mobile phone is 0 degrees to 180 degrees. In this case, the mobile phone uses a combination of a shaft cover, a support plate and a middle frame to effectively block the rotation mechanism of the mobile phone.

[0003] However, a mobile phone that can rotate within a range of 360 degrees can be in an inward folded state or an outward folded state. Since the mobile phone has a large rotation angle range, the rotation mechanism shielding solution used in inward folding or outward folding mobile phones is not suitable for mobile phones that can rotate within a range of 360 degrees. A new solution needs to be designed to shield the rotation mechanism of the mobile phone. Summary of the invention

[0004] The present application provides a foldable electronic device and a rotating mechanism. The foldable electronic device can be rotated within a range of 360 degrees, and the rotating mechanism is effectively shielded.

[0005] In a first aspect, the present application provides a foldable electronic device, comprising: a shell, a cover assembly and a rotating mechanism, the rotating mechanism comprising a fixing part and a bearing base, and the cover assembly comprising a main cover plate and a sub-cover plate. Along the length direction of the foldable electronic device, the fixing part is fixed to one side of the shell, the bearing base is movably connected to the side of the fixing part away from the shell, a first gap is provided between the shell and the fixing part, and a second gap is provided between the fixing part and the bearing base. The bearing base is movably connected to the fixing part, which means that the bearing base can be connected to the fixing part through components such as a main swing arm and a sub-swing arm. When the foldable electronic device switches between the inward folding state, the flattened state and the outward folding state, the main swing arm and the sub-swing arm will move relative to the bearing base, so that the fixing part moves relative to the bearing base.

[0006] In the thickness direction of the foldable electronic device, the main cover plate is stacked on the housing and the rotating mechanism, and the auxiliary cover plate is stacked on the rotating mechanism. The main cover plate and the auxiliary cover plate are arranged along the length direction. The main cover plate is slidably connected to the housing and the fixing member, and the main cover plate can slide relative to the housing and the fixing member along the length direction. The main cover plate is rotatably connected to the auxiliary cover plate. The auxiliary cover plate is rotatably connected to the bearing base.

[0007] The main cover plate covers the fixing member, the first gap and a part of the second gap, and the auxiliary cover plate covers the other part of the second gap and the bearing base.

[0008] In the related art, the foldable electronic device can rotate within a range of 180 degrees. In order to prevent foreign matter such as dust from entering the rotating mechanism, and to maintain the aesthetics of the foldable electronic device, a receiving cavity is provided on the opposite side of the two shells, and an appearance shaft cover is provided on the side of the supporting base away from the display screen. When the foldable electronic device is in the unfolded state, the rotating mechanism is stored in the receiving cavity of the shell, that is, the shell can cover the rotating mechanism. When the foldable electronic device is in the folded state, the side of the appearance shaft cover of the supporting base is in contact with the side of the shell, that is, the appearance shaft cover and the shell can cover the rotating mechanism.

[0009] In the present application, the foldable electronic device can rotate within a range of 360 degrees. When the foldable electronic device rotates to switch between the inward folding state, the flattened state and the outward folding state, the main cover plate and the auxiliary cover plate always keep covering the rotating mechanism, that is, the main cover plate and the auxiliary cover plate can cover the fixing member, the first gap between the housing and the fixing member, the second gap between the fixing member and the bearing base, and the bearing base, to prevent the fixing member, the first gap between the housing and the fixing member, the second gap between the fixing member and the bearing base, etc. from being exposed. This prevents foreign matter such as dust from entering the first gap and the second gap, prevents the user's fingers from being pinched, and increases the aesthetics of the foldable electronic device.

[0010] In some embodiments, along the length direction, the main cover plate and the auxiliary cover plate are arranged in sequence and in contact, and when the foldable electronic device switches between the inward folded state, the flattened state, and the outward folded state, the main cover plate and the auxiliary cover plate rotate around the first virtual axis at the same time. The first virtual axis is parallel to the width direction of the foldable electronic device and is located at the position where the main cover plate and the auxiliary cover plate are in contact.

[0011] Therefore, during the rotation process, the main cover plate and the auxiliary cover plate always maintain contact with each other, and no large gap will appear, thereby avoiding the problem of the rotation mechanism located below the contact part between the main cover plate and the auxiliary cover plate being exposed.

[0012] In some embodiments, a rotation protrusion is provided on the surface of the main cover plate facing the second slit, the surface of the main cover plate facing the second slit is the top surface of the main cover plate, and the rotation protrusion is provided with a first rotation groove. A first rotation member is provided on the surface of the auxiliary cover plate facing the second slit, and the surface of the auxiliary cover plate facing the second slit is the top surface of the auxiliary cover plate. The first rotation member is rotationally connected to the first rotation groove, and the center of the circle where the first rotation member is located and the center of the circle where the first rotation groove is located are both located on the first virtual axis. The virtual rotation connection between the main cover plate and the auxiliary cover plate is realized by the first rotation member and the first rotation groove, and the structure is simple and easy to realize.

[0013] In some embodiments, when the foldable electronic device switches between the inward folding state, the flattened state and the outward folding state, the secondary cover rotates around the second virtual axis, which is parallel to the width direction of the foldable electronic device and is located at the contact position between the secondary cover and the supporting base.

[0014] Therefore, during the rotation process, the auxiliary cover plate and the bearing base always maintain contact with each other, and no large gap will appear, thereby preventing the rotating mechanism from being exposed.

[0015] In some embodiments, the bearing base is provided with a second rotation groove, the surface of the auxiliary cover plate facing the bearing base is provided with a second rotation member, and the surface of the auxiliary cover plate facing the bearing base is the top surface of the auxiliary cover plate. The second rotation member is rotationally connected to the second rotation groove. The center of the circle where the second rotation member is located and the center of the circle where the second rotation groove is located are both located on the second virtual axis. The virtual rotation connection between the bearing base and the auxiliary cover plate is realized by the second rotation member and the second rotation groove, and the structure is simple and easy to realize.

[0016] In some embodiments, the fixing member is provided with first slide rails at opposite ends along the width direction of the foldable electronic device. The housing is provided with second slide rails at opposite ends along the width direction, the first slide rail and the second slide rail both extend along the length direction, and the main cover is provided with sliding blocks at opposite ends along the width direction, and the sliding blocks are provided with sliding grooves. The first slide rail and the second slide rail are slidably connected to the sliding groove.

[0017] Through the cooperation of the first slide rail, the second slide rail and the slide groove, the main cover plate is slidably connected to the shell, so that the main cover plate and the fixing member are slidably connected. The sliding of the main cover plate can be guided, making the sliding of the main cover plate more stable, and the structure is simple and easy to implement.

[0018] It can be understood that when the foldable electronic device switches between the three states, the main cover plate and the auxiliary cover plate rotate around the first virtual axis at the same time, and the auxiliary cover plate also rotates around the second virtual axis, that is, the main cover plate and the auxiliary cover plate are virtually connected in rotation, and the auxiliary cover plate and the bearing base are virtually connected in rotation, and then the main cover plate slides relative to the shell and the fixing member. Therefore, when the foldable electronic device switches between the three states, and when the foldable electronic device remains in one of the three states, the main cover plate and the auxiliary cover plate always keep covering the gap between the shell and the rotating mechanism and the state of covering the rotating mechanism, thereby preventing the rotating mechanism from being exposed. It can prevent foreign matter such as dust from entering the rotating mechanism, thereby preventing foreign matter from affecting the operation of the rotating mechanism. In addition, it prevents the user from reaching into the second gap when operating the foldable electronic device, thereby preventing the user's hand from being pinched. In addition, the aesthetics of the foldable electronic device can also be increased.

[0019] In some embodiments, a receiving groove is formed on the surface of the housing, the main cover extends into the receiving groove, and the surface of the main cover facing away from the fixing member is flush with the surface of the housing. Thus, the compactness and aesthetics of the foldable electronic device can be increased.

[0020] In some embodiments, the bearing base is provided with a bearing baffle and a covering groove at both opposite ends along the width direction of the foldable electronic device, and one side of the bearing baffle in the width direction is a groove side of the covering groove. The main cover is provided with a main baffle at both opposite ends along the width direction, and the auxiliary cover is provided with an auxiliary baffle at both opposite ends along the width direction. A portion of the auxiliary baffle extends into the covering groove, and another portion of the auxiliary baffle extends toward the main cover. Along the width direction, a portion of the auxiliary baffle is stacked with the bearing baffle, and another portion of the auxiliary baffle is stacked with the main baffle.

[0021] The stacking relationship of the main baffle, the auxiliary baffle and the bearing baffle is used to cover the gaps at both ends of the rotating mechanism along the Y-axis direction to prevent foreign matter such as dust from entering the rotating mechanism.

[0022] In some embodiments, the fixing member is provided with fixed baffles at opposite ends along the width direction of the foldable electronic device. Along the width direction, a portion of the fixed baffle is stacked with the main baffle, and another portion of the fixed baffle is stacked with the auxiliary baffle, and the fixed baffle covers the portion where the main baffle and the auxiliary baffle are stacked.

[0023] A fixed baffle is used to cover the position where the main baffle and the auxiliary baffle are stacked to prevent foreign matter such as dust from entering the interior of the rotating mechanism due to a short stacking length of the main baffle and the auxiliary baffle.

[0024] In some embodiments, the foldable electronic device further comprises a secondary swing arm, the secondary swing arm is rotatably connected to the bearing base, and the secondary swing arm is rotatably and slidably connected to the fixing member. A portion of the secondary swing arm is located in the second gap. The main cover plate and the secondary cover plate cover the portion of the secondary swing arm located in the second gap. That is, the main cover plate and the secondary cover plate can cover the secondary swing arm to prevent the secondary swing arm from being exposed.

The support plate is rotatably and slidably connected to the fixing member, and the support plate is rotatably and rotatably connected to the secondary swing arm. The support plate is used to support the display screen. The support plate can provide a flat surface to support the display screen, so that the display screen remains flat when the foldable electronic device is in a flattened state.

[0026] In some embodiments, the foldable electronic device further comprises a main swing arm, which is rotatably and slidably connected to the bearing base, and is fixedly connected to the fixing member. A portion of the main swing arm is located in the second gap. The main cover plate and the auxiliary cover plate cover the portion of the main swing arm located in the second gap. That is, the main cover plate and the auxiliary cover plate can cover the main swing arm to prevent the main swing arm from being exposed.

[0027] In some embodiments, the main swing arm includes a main sliding part and a fixed part fixedly connected along the length direction; the main sliding part rotates and slides to be connected to the supporting base, a part of the fixed part is fixedly connected to the fixing member, and another part of the fixed part is located in the second gap; a first fixing groove is provided on the surface of the fixing member facing the main cover plate, and the fixing part is fixed in the first fixing groove.

[0028] In some embodiments, a fixing ear is provided on one side of the housing facing the fixing member; a second fixing groove is provided on the surface of the fixing member facing the main cover plate, and the fixing ear is fixed in the second fixing groove. Thus, the part where the housing and the fixing member are fixedly connected is relatively flat, which can improve the compactness of the structure of the foldable electronic device.

[0029] In some embodiments, the housing includes a first housing and a second housing, the main cover includes a first main cover and a second main cover, and the auxiliary cover includes a first auxiliary cover and a second auxiliary cover.

The second main cover is slidably connected to the second shell and the second fixing member, and the second main cover is rotatably connected to the second sub-cover. The first sub-cover and the second sub-cover are both rotatably connected to the bearing base. Along the length direction of the foldable electronic device, the first main cover, the first sub-cover, the second sub-cover and the second main cover are arranged in sequence.

The second sub-cover covers another part of the second gap between the second fixing member and the bearing base, and another part of the bearing base.

[0030] When the foldable electronic device is in a flattened state, the first main cover plate, the first sub-cover plate, the second sub-cover plate and the second main cover plate are arranged in sequence and in contact along the length direction of the foldable electronic device to better cover the gap between the rotating mechanism and its accessories. The contact here includes the errors caused by the processing and assembly process. For example, if there is a 0.2mm gap between the first sub-cover plate and the second sub-cover plate, it can also be regarded as the first sub-cover plate and the second sub-cover plate contacting each other.

DETAILED DESCRIPTION

[0076] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0077] The embodiment of the present application provides a foldable electronic device 1000, and the foldable electronic device 1000 includes but is not limited to a cell phone, a notebook computer, a tablet personal computer, a personal digital assistant, a wearable device, or a mobile device, etc. In some embodiments, the foldable electronic device 1000 is described as a foldable mobile phone.

[0078] Foldable mobile phones include horizontal foldable phones and vertical foldable phones. A horizontal foldable phone can be folded along its width. After folding, the width of the phone is half of that when it is unfolded. A vertical foldable phone can be folded along its length. After folding, the length of the phone is half of that when it is unfolded.

[0079] Generally, horizontal folding machines are mostly large-screen mobile phones, also known as large folding machines. Here, large screen means that when the horizontal folding machine is in an unfolded state, the area of ​​the display screen 300 of the horizontal folding machine is approximately twice the area of ​​the display screen 300 of the straight-bar mobile phone. Vertical folding machines are mostly small-screen mobile phones, also known as small folding machines. When the vertical folding machine is in an unfolded state, the area of ​​the display screen 300 of the vertical folding machine is basically the same as the area of ​​the display screen 300 of the straight-bar mobile phone. Of course, the area of ​​the display screen 300 of the horizontal folding machine can also be the same as the area of ​​the display screen 300 of the straight-bar mobile phone, or other multiples of the area of ​​the display screen 300 of the straight-bar mobile phone, such as 1.5 times, 2.1 times or 2.5 times, etc. The area of ​​the display screen 300 of the vertical folding machine can also be 1.2 times, 1.5 times or 2 times, etc., of the area of ​​the display screen 300 of the straight-bar mobile phone. In this embodiment, a vertical folding machine is used as an example for explanation.

The main body 200 also includes a covering assembly 70. The covering assembly 70 is used to cover the rotating mechanism 100.

[0085] The display screen 300 may be a flexible screen. The display screen 300 includes a display surface and a mounting surface, and the display surface and the mounting surface are arranged opposite to each other. The display surface is used to display text, images, and videos. The display screen 300 includes a first display portion 310, a second display portion 320, and a third display portion 330. The third display portion 330 is located between the first display portion 310 and the second display portion 320.

[0086] The display screen 300 is mounted on the main body 200, and the mounting surface is fixedly connected to the main body 200, and the display surface is away from the main body 200. Specifically, the first display part 310 and the second display part 320 are fixedly mounted on the two shells 200A respectively. Among them, the rotating mechanism 100 is arranged opposite to the third display part 330 to realize the bending of the display screen 300. The third display part 330 is not fixed to the rotating mechanism 100. The width of the third display part 330 along the X-axis direction can be greater than or equal to the width of the rotating mechanism 100. The side of the two shells 200A facing away from the display screen 300 is the outer side of the electronic device, and the side carrying the display screen 300 is the inner side.

[0087] The main body 200 includes two shells 200A and a rotating mechanism 100. The two shells 200A are respectively a first shell 210 and a second shell 220. The rotating mechanism 100 is arranged between the first shell 210 and the second shell 220. The rotating mechanism 100 is respectively fixedly connected to the first shell 210 and the second shell 220 to realize the rotation connection between the first shell 210 and the second shell 220, and the first shell 210 and the second shell 220 can be relatively rotated through the rotating mechanism 100, so that the main body 200 can switch between the folded state and the unfolded state. The first shell 210 carries the first display unit 310, and the second shell 220 carries the second display unit 320. The rotating mechanism 100 is arranged opposite to the third display unit 330.

[0088] refer to Figure 5 , Figure 51 is a schematic diagram of the state transformation process of the foldable electronic device 1000 provided in an embodiment of the present application. The first shell 210 and the second shell 220 can be relatively rotated by the rotating mechanism 100, so that the foldable electronic device 1000 can switch between the inward folding state, the flattened state and the outward folding state. Specifically, when the foldable electronic device 1000 is in the inward folding state, the display screen 300 is located on the inner side of the main body 200 and is in an invisible state. The first shell 210 and the second shell 220 are rotated by the rotating mechanism 100 and move away from each other. During this process, the angle between the first shell 210 and the second shell 220 gradually increases from 0 degrees to 90 degrees. At this time, the foldable electronic device 1000 is in an inward half-folded state, and the display screen 300 is at least partially bent. When the first shell 210 and the second shell 220 continue to move away from each other, the angle between the first shell 210 and the second shell 220 gradually becomes 180 degrees. At this time, the foldable electronic device 1000 is in a flattened state, and the display screen 300 is flattened to have a larger display area. If the first shell 210 and the second shell 220 continue to rotate, the first shell 210 and the second shell 220 begin to approach each other again. During this process, the angle between the first shell 210 and the second shell 220 gradually increases from 180 degrees to 270 degrees. At this time, the foldable electronic device 1000 is in an outward half-folded state, and the display screen 300 is at least partially bent, and the bending direction is opposite to the bending direction of the inward half-folded state. When the first shell 210 and the second shell 220 continue to approach each other, the angle between the first shell 210 and the second shell 220 gradually becomes 360 degrees. At this time, the foldable electronic device 1000 is in an outward folded state, and the display screen 300 is located outside the main body 200 and is in a visible state.

[0090] When the foldable electronic device 1000 is in the unfolded state, the display screen 300 has a large display area, realizing the large-screen display and operation functions of the foldable electronic device 1000, and improving the user experience. When the foldable electronic device 1000 is in the inward folded state, the display screen 300 is between the first shell 210 and the second shell 220. The first shell 210 and the second shell 220 protect the display surface of the display screen 300, which can greatly reduce the probability of the display screen 300 being damaged, and the overall size is reduced, which is easy to carry. When the foldable electronic device 1000 is in the outward folded state, the display screen 300 is located at the outermost side, which is convenient for users to use the foldable electronic device 1000 as a small-screen device.

[0091] When the foldable electronic device 1000 switches between the three states, the covering component 70 can cover the rotating mechanism 100 to prevent the rotating mechanism 100 from being exposed, to prevent dust and other foreign objects from entering the rotating mechanism 100, and to prevent the rotating mechanism 100 from being exposed to the outside and pinching the user's fingers during operation.

[0111] After the main swing arm assembly 30 and the synchronous damping assembly 40 are assembled, a second gap 120 is provided between the fixing member 20A and the bearing base 10 along the X-axis direction. When the foldable electronic device 1000 switches between the inner state, the flattened state and the outer folded state, the main swing arm 30A and the auxiliary swing arm 40A both require a certain amount of activity space, and the second gap 120 between the fixing member 20A and the bearing base 10 can meet the needs of the main swing arm 30A and the auxiliary swing arm 40A for activity space, so that the foldable electronic device 1000 can smoothly switch between the three states.

The main cover plate 70A is slidably connected to the housing 200A and the fixing member 20A. Fig. 27 , Fig. 27 It is another cross-sectional structural schematic diagram of the main body 200 of the foldable electronic device 1000 provided in an embodiment of the present application when it is in a flattened state. The main cover plate 70A is stacked on the shell 200A and the fixing member 20A, and the auxiliary cover plate 70B is stacked on the bearing base 10. The main cover plate 70A is slidably connected to the shell 200A and the fixing member 20A, the main cover plate 70A is rotatably connected to the auxiliary cover plate 70B, and the auxiliary cover plate 70B is rotatably connected to the bearing base 10. Specifically, the first main cover plate 71 is stacked on the first shell 210 and the first fixing member 21, the first main cover plate 71 is slidably connected to the first shell 210 and the first fixing member 21, and the first main cover plate 71 is rotatably connected to the first auxiliary cover plate 73.

The second main cover plate 72 is slidably connected to the second shell 220 and the second fixing member 22, and the second main cover plate 72 is rotatably connected to the second auxiliary cover plate 74. The first sub-cover plate 73 and the second sub-cover plate 74 are both stacked on the bearing base 10, and the first sub-cover plate 73 and the second sub-cover plate 74 are respectively rotatably connected to the bearing base 10. In detail, a portion of the main cover plate 70A extends into the receiving groove 250 of the housing 200A, the bottom surface of the main cover plate 70A is flush with the bottom surface of the housing 200A, another portion of the main cover plate 70A extends out of the receiving groove 250, and another portion of the main cover plate 70A is stacked on the rotating mechanism 100 to cover the first gap 110, the fixing member 20A, and a portion of the second gap 120. It can be understood that in some embodiments, the receiving groove 250 may not be provided, and the cover assembly 70 may be directly stacked on the bottom surface of the housing 200A.

[0115] The sliding block 76 of the main cover plate 70A is slidably connected to the first slide rail 28 of the fixing member 20A and the second slide rail 230 of the housing 200A. In other words, the first slide rail 28 and the second slide rail 230 extend into the guide groove 78 of the sliding block 76, and the first slide rail 28 and the second slide rail 230 can slide in the guide groove 78, so that the main cover plate 70A can slide relative to the housing 200A along the X-axis direction, and the main cover plate 70A can slide relative to the fixing member 20A along the X-axis direction. The auxiliary cover plate 70B is located on the side of the main cover plate 70A away from the housing 200A, and the bottom surface of the auxiliary cover plate 70B is flush with the bottom surface of the main cover plate 70A. The auxiliary cover plate 70B is stacked on the rotating mechanism 100 to cover the rotating mechanism 100. Along the X-axis direction, the rotating protrusion 75 of the main cover plate 70A extends toward the auxiliary cover plate 70B, and the first rotating member 79 of the auxiliary cover plate 70B extends toward the main cover plate 70A. Along the Z-axis direction, a portion of the rotating protrusion 75 is projected on the upper surface of the auxiliary cover plate 70B, and a portion of the first rotating member 79 is projected on the upper surface of the main cover plate 70A, so that the rotating protrusion 75 and the first rotating member 79 can be smoothly connected. Among them, the rotating protrusion 75 of the main cover plate 70A is rotatably connected to the first rotating member 79 of the auxiliary cover plate 70B. In other words, the first rotating member 79 extends into the first rotating groove 751 of the rotating protrusion 75, and the first rotating member 79 can slide in the first rotating groove 751, so that the main cover plate 70A and the auxiliary cover plate 70B can rotate relative to each other, and the main cover plate 70A and the auxiliary cover plate 70B can rotate around the first virtual axis L1 at the same time. The first virtual axis L1 is the position where the edge of the top surface of the main cover plate 70A and the edge of the top surface of the auxiliary cover plate 70B contact each other. The center A1 of the circle where the first rotating member 79 is located and the center A2 of the circle where the first rotating groove 751 is located are both located on the first virtual axis L1. The second rotating member 80 of the auxiliary cover 70B is rotatably connected to the second rotating groove 17 of the supporting base 10. In other words, the second rotating member 80 can extend into the second rotating groove 17 and can slide in the second rotating groove 17 so that the auxiliary cover 70B can rotate relative to the supporting base 10. The auxiliary cover 70B rotates around the second virtual axis L2. The second virtual axis L2 is the position where the edge of the top surface of the auxiliary cover 70B contacts the outer surface of the decorative panel 13 of the supporting base 10. The center B1 of the circle where the second rotating member 80 is located and the center B2 of the circle where the second rotating groove 17 is located are both located on the second virtual axis L2.

[0116] In the related art, the foldable electronic device 1000 can rotate within a range of 180 degrees. In order to prevent foreign objects such as dust from entering the rotating mechanism 100, and to maintain the aesthetics of the foldable electronic device 1000, a receiving cavity is provided on the opposite side of the two shells 200A, and an appearance shaft cover 12 is provided on the side of the supporting base 10 away from the display screen 300. When the foldable electronic device 1000 is in the unfolded state, the rotating mechanism 100 is stored in the receiving cavity of the shell 200A, that is, the shell 200A can cover the rotating mechanism 100. When the foldable electronic device 1000 is in the folded state, the side of the appearance shaft cover 12 of the supporting base 10 is in contact with the side of the shell 200A, that is, the appearance shaft cover 12 and the shell 200A can cover the rotating mechanism 100.

[0117] However, when the foldable electronic device 1000 can rotate within a range of 360 degrees, if the housing 200A is still provided with a receiving cavity, the housing 200A will interfere with the rotating mechanism 100, thereby causing the foldable electronic device 1000 to be unable to rotate 360 ​​degrees. In the embodiment of the present application, the housing 200A and the fixing member 20A are provided to be in contact in the X-axis direction, and in the Z-axis direction, except for the fixing ear 240, other positions of the housing 200A are not stacked with the fixing member 20A. However, in this way, the fixing member 20A, the bearing base 10, the first gap 110 between the housing 200A and the fixing member 20A, the second gap 120 between the fixing member 20A and the bearing base 10, the portion of the main swing arm assembly 30 located in the second gap 120, and the portion of the synchronous damping assembly 40 located in the second gap 120 are all exposed. In this case, foreign matter such as dust can easily enter the interior of the rotating mechanism 100 from the first gap 110 and the second gap 120, thereby causing damage to the rotating mechanism 100. In addition, when the user operates the foldable electronic device 1000 to switch states, the user's fingers are easily pinched. In addition, the components of the rotating mechanism 100 are exposed to the outside, resulting in poor aesthetics of the foldable electronic device 1000.

[0118] In the embodiment of the present application, when the foldable electronic device 1000 switches between the three states, the main cover plate 70A and the auxiliary cover plate 70B always keep covering the rotating mechanism 100, preventing the fixing member 20A, the bearing base 10, the first gap 110 between the housing 200A and the fixing member 20A, the second gap 120 between the fixing member 20A and the bearing base 10, the part of the main swing arm assembly 30 located in the second gap 120, and the part of the synchronous damping assembly 40 located in the second gap 120 from being exposed. This prevents foreign matter such as dust from entering the first gap 110 and the second gap 120, prevents the user's fingers from being pinched, and increases the aesthetics of the foldable electronic device 1000.

[0119] Specifically, when the foldable electronic device 1000 switches between the inward folding state, the flattened state, and the outward folding state, the two shells 200A rotate relative to each other, the fixed portion 33 of the main swing arm 30A rotates synchronously with the shell 200A, and the main sliding portion 34 of the main swing arm 30A slides and rotates along the main connecting member 14. The secondary sliding portion 48 of the secondary swing arm 40A slides and rotates relative to the fixed member 20A, and the rotating portion of the secondary swing arm 40A rotates relative to the supporting base 10. The support plate 60A slides and rotates relative to the secondary swing arm 40A, and slides and rotates relative to the fixed member 20A. The main cover plate 70A slides relative to the shell 200A, and rotates relative to the secondary cover plate 70B. While the secondary cover plate 70B rotates relative to the main cover plate 70A, it also rotates relative to the supporting base 10.

[0120] refer to Fig.26 and Fig. 27 When the foldable electronic device 1000 is in a flattened state, the top surface of the housing 200A, the top surface of the support plate 60A and the top surface of the supporting base 10 are arranged in sequence and flush along the X-axis direction to support the display screen 300, so that the display screen 300 remains flat. The bottom surface of the housing 200A, the bottom surface of the main cover plate 70A and the bottom surface of the auxiliary cover plate 70B are arranged in sequence and flush along the X-axis direction to keep the appearance of the housing 200A flat. Along the X-axis direction, there is a first gap between the side of the main cover plate 70A and the side of the storage groove 250, so that the main cover plate 70A can have sufficient space for movement in the X-axis direction. Furthermore, at this time, the main cover 70A covers the following parts: the first gap 110 between the housing 200A and the fixing member 20A, the fixing member 20A, a part of the second gap 120 between the fixing member 20A and the bearing base 10, a part of the main swing arm 30A and a part of the auxiliary swing arm 40A located in the second gap 120. The auxiliary cover 70B and the main cover 70A are arranged and contacted along the X-axis direction, and the contact here includes processing and assembly errors. The auxiliary cover 70B covers the following parts: another part of the second gap 120 between the fixing member 20A and the bearing base 10, another part of the main swing arm 30A and another part of the auxiliary swing arm 40A located in the second gap 120, and the bearing base 10. In other words, the main cover 70A and the auxiliary cover 70B cover the gap between the housing 200A and the rotating mechanism 100, and cover the rotating mechanism 100.

[0121] It can be understood that in order to better cover the rotating mechanism 100, the first sub-cover plate 73 and the second sub-cover plate 74 are in contact with each other along the X-axis direction. The contact here includes processing and assembly errors. For example, a gap of less than 2 mm between the first sub-cover plate 73 and the second sub-cover plate 74 can also be regarded as the two being in contact with each other.

[0122] refer to Fig.28 , Fig.29 and Fig.30 , Fig.282 is a schematic structural diagram of a foldable electronic device 1000 provided in an embodiment of the present application, wherein the main body 200 is in an inwardly folded state. Fig.29 is a schematic cross-sectional view of the main body 200 of the foldable electronic device 1000 provided in an embodiment of the present application in an inwardly folded state. Fig.30 It is another cross-sectional structural schematic diagram of the main body 200 of the foldable electronic device 1000 provided by the embodiment of the present application in the inward folded state. When the foldable electronic device 1000 is in the inward folded state, the two shells 200A are stacked along the Z axis direction instead of being laid flat along the X axis direction, the supporting base 10 is located between the two shells 200A, and there is an angle of about 90 degrees between the bottom surface of the supporting base 10 and the bottom surface of the shell 200A, and the display screen 300 is located inside and is in a hidden state. The main cover plate 70A and the auxiliary cover plate 70B are located at the outermost side and are in a visible state. At this time, the second gap 120 between the fixing member 20A and the bearing base 10 becomes larger, the main cover plate 70A slides relative to the shell 200A along the X-axis direction, and the main cover plate 70A slides in the direction away from the shell 200A, so that the part of the main cover plate 70A extending out of the storage groove 250 increases, and there is a second gap between the side of the main cover plate 70A and the side of the storage groove 250. Along the X-axis direction, the second gap is larger than the first gap. To better cover the enlarged second gap 120 between the fixing member 20A and the bearing base 10. The first rotating member 79 slides in the first rotating groove 751, and the part of the first rotating member 79 extending into the first rotating groove 751 increases. The second rotating member 80 slides in the second rotating groove 17, and the part of the second rotating member 80 extending into the second rotating groove 17 increases. The auxiliary cover 70B and the main cover 70A are no longer flush along the X-axis direction. At this time, there is an angle of about 100 degrees between the auxiliary cover 70B and the main cover 70A, so that the auxiliary cover 70B can cover the bearing base 10. In addition, when the foldable electronic device 1000 switches from the flat state to the inward folding state, the auxiliary cover 70B and the main cover 70A are rotated, so that when the foldable electronic device 1000 is in the inward folding state, the surface of the auxiliary cover 70B facing the bearing base 10 and the surface of the bearing base 10 facing the auxiliary cover 70B are parallel to each other, and the surface of the auxiliary cover 70B facing the bearing base 10 and the surface of the bearing base 10 facing the auxiliary cover 70B are both inclined surfaces. Compared with the solution in which the auxiliary cover 70B is perpendicular to the main cover 70A, the space between the auxiliary cover 70B and the bearing base 10 is reduced, which can increase the structural compactness of the foldable electronic device 1000. It can be seen that when the foldable electronic device 1000 is in the inward folded state, the main cover 70A and the auxiliary cover 70B keep covering the gap between the housing 200A and the rotating mechanism 100 and covering the rotating mechanism 100 .

[0123] refer to Fig.31 , Fig.32 and Fig.33 , Fig.312 is a schematic structural diagram of a foldable electronic device 1000 provided in an embodiment of the present application, in which the main body 200 is in an outwardly folded state. Fig.32 is a schematic cross-sectional view of the main body 200 of the foldable electronic device 1000 provided in an embodiment of the present application in an outwardly folded state. Fig.33 This is another cross-sectional structural schematic diagram of the main body 200 of the foldable electronic device 1000 provided in an embodiment of the present application in an outwardly folded state.

[0124] When the foldable electronic device 1000 is in an outward folded state, the two shells 200A are stacked in the Z-axis direction instead of being laid flat along the X-axis direction, the bearing base 10 is located between the two shells 200A, and there is an angle of about 90 degrees between the bottom surface of the bearing base 10 and the bottom surface of the shell 200A, and the display screen 300 is located outside and is visible. The main cover plate 70A and the auxiliary cover plate 70B are located at the innermost side and are in a hidden state. At this time, the main cover plate 70A moves in the direction close to the shell 200A along the X-axis direction, that is, the part of the main cover plate 70A extending into the storage groove 250 increases, and the part of the main cover plate 70A extending out of the storage groove 250 decreases. The side of the main cover plate 70A and the groove side of the storage groove 250 can contact. The main cover plate 70A covers the first gap 110 and a part of the fixing member 20A. The auxiliary cover plate 70B covers another part of the fixing member 20A and the second gap 120. The first rotating member 79 slides in the first rotating groove 751, and the portion of the first rotating member 79 extending into the first rotating groove 751 is reduced, and the second rotating member 80 slides in the second rotating groove 17, and the portion of the second rotating member 80 extending into the second rotating groove 17 is reduced. It can be seen that when the foldable electronic device 1000 is in the outward folded state, the main cover plate 70A and the auxiliary cover plate 70B still maintain the state of covering the gap between the housing 200A and the rotating mechanism 100 and covering the rotating mechanism 100. It can be understood that when the foldable electronic device 1000 is in the outward folded state, although the positional relationship between the supporting base 10 and the auxiliary cover plate 70B changes, the inner side of the supporting base 10 located in the foldable electronic device 1000 is still blocked by the auxiliary cover plate 70B, and the side of the supporting base 10 facing the display screen is blocked by the display screen. The supporting base 10 is still in a blocked state.

[0125] refer to Fig.34 , Fig.341 is a process diagram of the main body 200 of the foldable electronic device 1000 provided in the embodiment of the present application switching between the inward folding state, the flattened state and the outward folding state. In the process of the foldable electronic device 1000 switching between the three states, the main cover plate 70A and the auxiliary cover plate 70B rotate around the first virtual axis L1 at the same time, and the auxiliary cover plate 70B rotates around the second virtual axis L2, that is, the main cover plate 70A and the auxiliary cover plate 70B are virtually connected in rotation, and the auxiliary cover plate 70B and the bearing base 10 are virtually connected in rotation, and then the main cover plate 70A slides relative to the housing 200A and the fixing member 20A. Therefore, when the foldable electronic device 1000 switches between the three states, and when the foldable electronic device 1000 remains in one of the three states, the main cover plate 70A and the auxiliary cover plate 70B always keep covering the gap between the housing 200A and the rotating mechanism 100 and the state of covering the rotating mechanism 100, thereby avoiding the exposure of the rotating mechanism 100. This can prevent foreign matter such as dust from entering the rotating mechanism 100, thereby preventing the foreign matter from affecting the operation of the rotating mechanism 100. In addition, it can prevent the user from inserting his hand into the second gap 120 when operating the foldable electronic device 1000, thereby preventing the user's hand from being pinched. In addition, the aesthetics of the foldable electronic device 1000 can also be improved.

[0126] It is also understandable, reference Fig.35 , Fig.35 yes Fig.21 Although the auxiliary cover 70B does not cover the fixing member 20A, the fixing baffle 23 of the fixing member 20A protrudes along the Y-axis direction toward the side of the fixing member 20A close to the supporting base 10, and the length of the fixing member 20A is smaller than the length of the auxiliary cover 70B. Therefore, along the Y-axis direction, the auxiliary cover 70B is located between the protruding parts of the two fixing baffles 23 of the fixing member 20A, that is, a part of the auxiliary baffle 81 and the fixing baffle 23 are stacked.

[0127] When the auxiliary cover 70B is stacked on the rotating mechanism 100 along the Z-axis direction to cover the supporting base 10, the auxiliary baffle 81 of the auxiliary cover 70B can extend into the covering groove 18 of the supporting base 10. At this time, along the Y-axis direction, a part of the auxiliary baffle 81 and a part of the supporting baffle 112 are stacked.

[0128] When the main cover 70A is stacked on the rotating mechanism 100 to cover the fixing part 20A and a part of the second gap 120, and the sub-cover 70B is stacked on the rotating mechanism 100 to cover the other part of the second gap 120, although the main cover 70A and the sub-cover 70B are not stacked in the Y-axis direction, the sub-baffle 81 extends obliquely along the Z-axis direction. Specifically, the sub-baffle 81 extends toward the side of the sub-cover 70B close to the main cover 70A. Combined with the fact that the length dimension of the sub-cover 70B is smaller than the length dimension of the main cover 70A, at this time, along the Y-axis direction, the two sub-baffles 81 are located in the interval between the two main baffles 77, and a part of the sub-baffle 81 is stacked with a part of the main baffle 77.

[0129] When the main cover 70A is stacked on the rotating mechanism 100 to shield the fixing member 20A, the fixing member 20A is located between the two main baffles 77 of the main cover 70A along the Y-axis direction, and a part of the main baffle 77 and a part of the fixing side plate are stacked.

[0130] In summary, it can be seen that along the X-axis direction, the auxiliary baffle 81 is located between the main baffle 77 and the bearing baffle 112. Along the Y-axis direction, a portion of the auxiliary baffle 81 is stacked with a portion of the main baffle 77, and another portion of the auxiliary baffle 81 is stacked with a portion of the bearing baffle 112. A portion of the fixed baffle 23 is stacked with a portion of the main baffle 77, and another portion of the fixed baffle 23 is stacked with a portion of the auxiliary baffle 81, and the fixed baffle 23 blocks the portion where the main baffle 77 and the auxiliary baffle 81 are stacked with each other. The stacking relationship of the main baffle 77, the auxiliary baffle 81, the fixed baffle 23, and the bearing baffle 112 is used to block the gaps at both ends of the rotating mechanism 100 along the Y-axis direction to prevent dust and other foreign matter from entering the rotating mechanism 100.

[0131] It is understood that when the foldable electronic device 1000 switches between the three states, the movements of the two housings 200A need to be synchronized, and damping force is also required during the rotation of the housing 200A. In this embodiment, synchronization and damping are both achieved by the synchronous damping assembly 40, which is described in detail below.

[0132] refer to Fig.36 and Fig.37 , Fig.36 yes Figure 8 The structural diagram of the synchronous damping assembly 40 of the rotating mechanism 100 is shown in FIG. Fig.37 yes Figure 8The synchronous damping assembly 40, the fixing assembly 20 and the bearing base 10 are shown in the figure. In addition to two auxiliary swing arms 40A (a first auxiliary swing arm 41 and a second auxiliary swing arm 42) and two mounting shafts (a first mounting shaft 44 and a second mounting shaft 45), the synchronous damping assembly 40 also includes four synchronous gears 43, a concave cam, two main elastic members, an auxiliary elastic member 55 and an auxiliary mounting shaft 56. The concave cam includes two first concave cams 51 and two second concave cams 52. The two main elastic members are respectively a first main elastic member 53 and a second main elastic member 54.

[0133] The two rotating parts of the auxiliary swing arm 40A are respectively the first rotating part 46 and the second rotating part 47, and the first rotating part 46 and the second rotating part 47 are spaced and opposite to each other along the Y-axis direction. The first auxiliary swing arm 41 and the second auxiliary swing arm 42 are both provided with concave-convex parts. Specifically, the first rotating part 46 is provided with a first concave-convex part 461 at one end facing the second rotating part 47, and the second rotating part 47 is provided with a second concave-convex part 471 at one end facing the first rotating part 46. The outer circumferences of the first rotating part 46 and the second rotating part 47 in the first auxiliary swing arm 41 are both provided with first driving teeth 411, and the outer circumferences of the first rotating part 46 and the second rotating part 47 in the second auxiliary swing arm 42 are both provided with second driving teeth 421.

[0134] The first rotating part 46 and the second rotating part 47 of the first auxiliary swing arm 41 are both sleeved on the first mounting shaft 44, and the first rotating part 46 and the second rotating part 47 can rotate around the axial direction of the first mounting shaft 44. The first rotating part 46 and the second rotating part 47 of the second auxiliary swing arm 42 are both sleeved on the second mounting shaft 45.

[0136] When the foldable electronic device 1000 switches between the folded state and the unfolded state, the auxiliary swing arm 40A can be used to realize the synchronous operation of the first shell 210 and the second shell 220 by setting the first driving tooth 411, the second driving tooth 421 and the synchronous gear 43. Specifically, the first shell 210 and the second shell 220 both rotate relative to the bearing base 10, the two main sliding parts 34 both rotate and slide relative to the bearing base 10, and the two fixing parts 33 rotate synchronously with the first fixing member 21 and the second fixing member 22. The first rotating part 46 and the second rotating part 47 of the first auxiliary swing arm 41 rotate relative to the bearing base 10, and the auxiliary sliding part 48 of the first auxiliary swing arm 41 slides relative to the first fixing member 21. The first rotating portion 46 and the second rotating portion 47 of the second auxiliary swing arm 42 rotate relative to the supporting base 10, and the auxiliary sliding portion 48 of the second auxiliary swing arm 42 slides relative to the second fixing member 22, and the first driving tooth 411, the synchronous gear 43 and the second driving tooth 421 are engaged in sequence to make the first auxiliary swing arm 41 and the second auxiliary swing arm 42 rotate synchronously, thereby realizing the synchronous rotation of the first shell 210 and the second shell 220.

[0137] When the foldable electronic device 1000 switches between the folded state and the unfolded state, the first housing 210 and the second housing 220 both rotate relative to the bearing base 10, the first rotating part 46 and the second rotating part 47 of the two auxiliary swing arms 40A both rotate relative to the bearing base 10, the matching state of the first concave-convex part 461 and the first matching concave-convex part 57 changes, and the matching state of the second concave-convex part 471 and the second matching concave-convex part 58 changes, so that the main elastic member and the auxiliary elastic member 55 are compressed or extended, thereby providing damping force for the first housing 210 and the second housing 220. The change in the matching state of the first concave-convex part 461 and the first matching concave-convex part 57 means that, as the auxiliary swing arm 40A rotates, the first concave-convex part 461 and the first matching concave-convex part 57 can switch between peak-to-valley matching and peak-to-peak matching. Peak-to-valley matching means that the convex part of the first concave-convex part 461 is located in the concave part of the first matching concave-convex part 57, and the convex part of the first matching concave-convex part 57 is located in the concave part of the first concave-convex part 461. Peak-to-peak matching refers to the contact between the convex part of the first concavoconvex part 461 and the convex part of the first matching concavoconvex part 57. The matching state change between the second concavoconvex part 471 and the second matching concavoconvex part 58 is similar to that between the first concavoconvex part 461 and the first matching concavoconvex part 57, and will not be repeated.
