Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to a folding device and electronic device. Background Technology

[0002] Flexible displays, due to their thinness, lightness, and durability, are widely used in various foldable electronic devices. Foldable electronic devices also include a folding mechanism to support the flexible display, which typically consists of two housings and a rotating mechanism connecting the housings. The two housings fold or unfold relative to each other through the deformation of the rotating mechanism, thereby causing the flexible display to fold or unfold.

[0003] Traditional folding devices typically use two or three shielding plates on the surface of the folding device facing away from the flexible display screen during folding or unfolding to conceal internal components and ensure the aesthetic appearance of the unfolded electronic device. However, the structure of these shielding plates needs to adapt to the rotation of the two housings, making their structure quite complex and hindering future maintenance and replacement. Summary of the Invention

[0004] This application provides a folding device that simplifies the form of the shielding structure, facilitating its later maintenance and replacement. This application also provides an electronic device equipped with this folding device. Specifically, it includes the following technical solutions:

[0005] In a first aspect, this application provides a folding device, comprising a first housing, a rotating mechanism, and a second housing connected in sequence. The rotating mechanism is deformable to fold or unfold the first housing relative to the second housing. The rotating mechanism includes a main shaft assembly, a first transmission arm, a first rotating arm, a first shielding member, a second transmission arm, a second rotating arm, and a second shielding member. One end of the first transmission arm is fixedly connected to the first housing, and the other end is rotatably connected to the main shaft assembly. The first rotating arm includes a first rotating end and a first sliding end. The first rotating end is rotatably connected to the main shaft assembly, and the first sliding end is slidably connected to the first transmission arm. The first shielding member... The first shielding component is located on the side of the first rotating arm away from the first transmission arm and is fixedly connected to the first sliding end; one end of the second transmission arm is fixedly connected to the second housing, and the other end is rotatably connected to the main shaft assembly. The second rotating arm includes a second rotating end and a second sliding end. The second rotating end is rotatably connected to the main shaft assembly, and the second sliding end is slidably connected to the second transmission arm. The second shielding component is located on the side of the second rotating arm away from the second transmission arm and is fixedly connected to the second sliding end. When the first housing and the second housing are unfolded relative to each other, the first sliding end and the second sliding end slide toward the main shaft assembly respectively, and the first shielding component and the second shielding component move closer to each other to shield the main shaft assembly.

[0006] This application's folding device achieves folding and unfolding actions between the first and second housings through a rotating mechanism. The rotating mechanism includes a main shaft assembly, which is rotatably connected to the first housing via a first transmission arm and to the second housing via a second transmission arm. The rotatable connections of the first and second rotating arms to the main shaft assembly respectively enable the sliding of the first and second shielding members relative to the first and second transmission arms. This allows the first and second shielding members to move closer together when the first and second housings are unfolded, thus shielding the main shaft assembly and preventing external moisture or dust from entering the interior of the folding device, while also improving the device's appearance.

[0007] In the folding device of this application, the first and second shielding members are respectively fixed to the first and second rotating arms, and are located on the side of the first and second rotating arms opposite to the main shaft assembly. The first and second shielding members slide relative to the main shaft assembly as the first and second rotating arms slide, achieving a shielding effect. The mechanism of the first and second shielding members relative to the main shaft assembly is relatively simple, and both are always exposed on one side of the main shaft assembly. When later maintenance and replacement are required, the first or second shielding member can be directly removed from the first or second rotating arm without further disassembly and assembly of the folding device, making the maintenance and replacement of the first and second shielding members relatively convenient.

[0008] In one possible implementation, the first rotating arm includes a first rotating member and a second rotating member, which are spaced apart along the length of the main shaft assembly, and the first shielding member is fixedly connected to both the first and second rotating members; the second rotating arm includes a third rotating member and a fourth rotating member, which are spaced apart along the length of the main shaft assembly, and the second shielding member is fixedly connected to both the third and fourth rotating members.

[0009] In this implementation, both the first and second shielding members are elongated, each positioned along the length of the main shaft assembly. The spacing between the first and second rotating members along the length of the main shaft assembly ensures a more stable connection between the elongated first shielding member and the first rotating arm, thereby guaranteeing the rotational posture of the first shielding member relative to the main shaft assembly. Similarly, the second shielding member, after being fixedly connected to the third and fourth rotating members respectively, also maintains its rotational posture relative to the main shaft assembly.

[0010] In one possible implementation, there are multiple first rotating members and multiple second rotating members, which are arranged at intervals along the length direction of the main shaft assembly. The first shielding member is fixedly connected to the multiple first rotating members and multiple second rotating members. There are also multiple third rotating members and multiple fourth rotating members, which are also arranged at intervals along the length direction of the main shaft assembly. The second shielding member is fixedly connected to the multiple third rotating members and multiple fourth rotating members.

[0011] In this implementation, multiple first rotating members and second rotating members are arranged along the length of the main shaft assembly, which can provide more fulcrums for the first shielding member and further ensure the rotational posture of the first shielding member; while the structure of multiple third rotating members and fourth rotating members also further ensures the rotational posture of the second shielding member.

[0012] In one possible implementation, the first rotating member includes a first spring, with its opposite ends abutting between a first rotating end and a first sliding end, for pushing the first sliding end away from the first rotating end; the third rotating member includes a second spring, with its opposite ends abutting between a second rotating end and a second sliding end, for pushing the second sliding end away from the second rotating end.

[0013] In this implementation, the first spring can generate a supporting force between the first rotating end and the first sliding end, and maintain the relative position between the first rotating end and the first sliding end by the supporting force when the folding device is unfolded; the second spring can also maintain the relative position between the second rotating end and the second sliding end. The folding device can only fold and flip under the action of an external force that is sufficient to overcome the supporting force provided by the first spring and the second spring, thereby maintaining the stability of the folding device in the unfolded state.

[0014] In one possible implementation, the rotating mechanism further includes a first engaging member and a second engaging member; the first engaging member is located between the first shielding member and the first transmission arm, and includes a third sliding end and a first engaging end opposite to each other, the third sliding end being slidably connected to the first transmission arm; the second engaging member is located between the second shielding member and the second transmission arm, and includes a fourth sliding end and a second engaging end opposite to each other, the fourth sliding end being slidably connected to the second transmission arm; the first engaging end and the second engaging end mesh with each other.

[0015] In this implementation, the mutual engagement of the first and second engaging members ensures that the first and second housings maintain an angularly symmetrical posture with respect to the main shaft assembly during unfolding or folding. Furthermore, the synchronous unfolding or folding of the first and second housings reduces the rotational stroke of the user operating the folding device of this application.

[0016] In one possible implementation, the first shielding member includes a first fixing member and a first cover plate. The first fixing member is fixedly connected to the first rotating member and the second rotating member respectively. The first cover plate is located on the side of the first fixing member opposite to the first rotating member and is fixedly connected to the first fixing member. The second shielding member includes a second fixing member and a second cover plate. The second fixing member is fixedly connected to the third rotating member and the fourth rotating member respectively. The second cover plate is located on the side of the second fixing member opposite to the third rotating member and is fixedly connected to the second fixing member.

[0017] In this implementation, by simultaneously fixing the first fixing member to both the first rotating member and the second rotating member, the positional accuracy of the first shielding member relative to the first rotating arm can be ensured. The first cover plate is used to achieve the shielding effect of the first shielding member. The second fixing member is also used to ensure the positional accuracy of the second shielding member relative to the second rotating arm, and the second cover plate is used to achieve the shielding effect of the second shielding member.

[0018] In one possible implementation, there are multiple first fixing members, each of which is fixedly connected to a number of first rotating members and second rotating members, and the first cover plate is simultaneously fixedly connected to multiple first fixing members; there are multiple second fixing members, each of which is fixedly connected to a number of third rotating members and fourth rotating members, and the second cover plate is simultaneously fixedly connected to multiple second fixing members.

[0019] In this implementation, multiple first fixing members can be arranged along the length of the main shaft assembly. Each first fixing member is fixedly connected to several first rotating members and second rotating members, which reduces the overall dimensional accuracy requirements of the first fixing members. The structure of multiple second fixing members also reduces the overall dimensional accuracy requirements, thereby helping to reduce the overall manufacturing cost of the folding device.

[0020] In one possible implementation, the relative positions of the first fixed member and the first rotating member, and / or the first fixed member and the second rotating member, and / or the second fixed member and the third rotating member, and / or the second fixed member and the fourth rotating member are fixed by the cooperation of a locating pin and a locating hole.

[0021] In this implementation, the relative position between the first fixed member and the first rotating member and / or the second rotating member can be fixed by the cooperation of the positioning pin and the positioning hole. When the same first fixed member is fixed to the relative position of several first rotating members and / or second rotating members by the cooperation of the positioning pin and the positioning hole, the relative positional accuracy between the first fixed member and the spindle assembly can be guaranteed because the first rotating members and the second rotating members are spaced apart along the length direction of the spindle assembly. The second fixed member can also guarantee its relative positional accuracy with the spindle assembly through a similar positioning method, thereby guaranteeing the positional accuracy of the first shielding member and the second shielding member relative to the spindle assembly.

[0022] In one possible implementation, the first cover plate is bonded to the first fastener, and the second cover plate is bonded to the second fastener.

[0023] In this implementation, the connection between the first cover plate and the first fixing member is such that the first cover plate and the first fixing member can be separated by means of heating, so that the first cover plate and the first fixing member can be repeatedly disassembled or replaced without damaging the relative positional accuracy between the first fixing member and the spindle assembly; correspondingly, the second cover plate and the second fixing member are also easy to disassemble or replace.

[0024] In one possible implementation, when the first housing and the second housing are deployed relative to each other, the gap width between the first shielding member and the second shielding member is less than or equal to 0.1 mm.

[0025] In this implementation, limiting the gap width between the first and second shielding components ensures the shielding effect of the first and second shielding components on the spindle assembly.

[0026] In one possible implementation, the spindle assembly includes a central spindle plate and a first side spindle plate and a second side spindle plate arranged on both sides of the central spindle plate. The first side spindle plate is connected between the central spindle plate and the first drive arm, and the second side spindle plate is connected between the central spindle plate and the second drive arm.

[0027] In this implementation, the arrangement of the first side shaft plate and the second side shaft plate increases the bending radius of the spindle assembly, so as to accommodate the outer thickness of the first housing and the second housing when they are folded relative to each other.

[0028] In one possible implementation, the first side shaft plate is rotatably connected to the central shaft plate, and the rotation center of the first side shaft plate is close to the first transmission arm and far away from the second side shaft plate; the second side shaft plate is rotatably connected to the central shaft plate, and the rotation center of the second side shaft plate is close to the second transmission arm and far away from the first side shaft plate.

[0029] In this implementation, the rotation center of the first side shaft plate and the rotation center of the second side shaft plate are spaced apart, which can further expand the bending radius of the main shaft assembly so as to accommodate the outer thickness of the first and second housings when the first housing and the second housing are folded relative to each other.

[0030] In one possible implementation, the first rotating arm is rotatably connected to the central shaft plate, and the rotation center of the first rotating arm is close to the first transmission arm and far away from the second transmission arm; the second rotating arm is rotatably connected to the central shaft plate, and the rotation center of the second rotating arm is close to the second rotating arm and far away from the first transmission arm.

[0031] In this implementation, the rotation center of the first rotating arm and the rotation center of the second rotating arm are spaced apart, which can expand the bending radius of the main shaft assembly corresponding to the regions of the first and second rotating arms, so as to accommodate the outer thickness of the first and second rotating arms when the first and second housings are folded relative to each other.

[0032] In one possible implementation, the first side shaft plate and the central shaft plate, and / or the second side shaft plate and the central shaft plate, and / or the first rotating arm and the central shaft plate, and / or the second rotating arm and the central shaft plate are rotatably connected by an arc-shaped groove and an arc-shaped slide rail.

[0033] In one possible implementation, the central shaft plate includes a first side edge near the first side shaft plate and a second side edge near the second side shaft plate. The first side edge is provided with a plurality of first arc-shaped grooves, and the second side edge is provided with a plurality of second arc-shaped grooves. The first side shaft plate is provided with a plurality of first arc-shaped slide rails, each of which extends into a first arc-shaped groove to achieve a rotational connection between the first side shaft plate and the central shaft plate. The second side shaft plate is provided with a plurality of second arc-shaped slide rails, each of which extends into a second arc-shaped groove to achieve a rotational connection between the second side shaft plate and the central shaft plate.

[0034] In one possible implementation, the first side is provided with multiple fifth arc-shaped grooves, and the second side is provided with multiple sixth arc-shaped grooves; the first rotating end of the first rotating arm is provided with multiple fifth arc-shaped slide rails, each fifth arc-shaped slide rail extending into a fifth arc-shaped groove to achieve a rotational connection between the first rotating end and the central shaft plate; the second rotating end of the second rotating arm is provided with multiple sixth arc-shaped slide rails, each sixth arc-shaped slide rail extending into a sixth arc-shaped groove to achieve a rotational connection between the second rotating end and the central shaft plate.

[0035] In one possible implementation, the central shaft plate includes a central inner plate and a central outer plate that are fixedly connected, with the central outer plate and the central inner plate interlocking to form multiple arcuate grooves.

[0036] In one possible implementation, the first transmission arm includes a third side near the first side shaft plate, the third side being provided with a plurality of third arc-shaped grooves, and the first side shaft plate being provided with a plurality of third arc-shaped slide rails, each third arc-shaped slide rail extending into a third arc-shaped groove to achieve a rotational connection between the first side shaft plate and the first transmission arm.

[0037] In one possible implementation, the second transmission arm includes a fourth side near the second side shaft plate, the fourth side being provided with a plurality of fourth arc-shaped grooves, and the second side shaft plate being provided with a plurality of fourth arc-shaped slide rails, each fourth arc-shaped slide rail extending into a fourth arc-shaped groove to achieve a rotational connection between the second side shaft plate and the second transmission arm.

[0038] In one possible implementation, the first transmission arm further includes a plurality of first slide rails, and the first rotating end of the first rotating arm includes a plurality of first slide grooves, with each first slide rail extending into a first slide groove to achieve a sliding connection between the first rotating arm and the first transmission arm.

[0039] In one possible implementation, the second drive arm further includes a plurality of second slide rails, and the second rotating end of the second rotating arm includes a plurality of second slide grooves, with each second slide rail extending into a second slide groove to achieve a sliding connection between the second rotating arm and the second drive arm.

[0040] In one possible implementation, the first transmission arm includes a first transmission inner plate and a first transmission outer plate fixedly connected, the first transmission inner plate and the first transmission outer plate being interlocked to form a plurality of arc-shaped grooves; the second transmission arm includes a second transmission inner plate and a second transmission outer plate fixedly connected, the second transmission inner plate and the second transmission outer plate being interlocked to form a plurality of arc-shaped grooves.

[0041] In a second aspect, this application provides an electronic device including a flexible display screen and a folding device provided in the first aspect of this application, wherein the flexible display screen covers the folding device and is located on the side of the main shaft assembly opposite to the first and second shielding members.

[0042] Understandably, the electronic device provided in this application, by employing the folding device described in the first aspect, enables a good shielding effect on the spindle assembly through the cooperation between the first and second shielding members when the first and second housings are unfolded relative to each other. Furthermore, because the positions of the first and second shielding members are always exposed outside the folding device, and the mechanisms of the first and second shielding members are relatively simple, this facilitates the maintenance and replacement of the first and second shielding members.

[0043] In one possible implementation, the flexible display screen includes a first non-bending portion, a bending portion, and a second non-bending portion arranged in sequence. The first non-bending portion is fixed to a first housing, and the second non-bending portion is fixed to a second housing. During the relative folding or unfolding of the first housing and the second housing, the bending portion is used to undergo adaptive deformation. Attached Figure Description

[0095] The following embodiments of this application will be described in conjunction with the accompanying drawings.

[0096] This application provides a folding device and an electronic device. The electronic device includes a folding device and a flexible display screen fixed to the folding device. The folding device can be unfolded to an unfolded state, folded to a closed state, or in an intermediate state between the unfolded and closed states. The flexible display screen unfolds and folds along with the folding device. By optimizing the main shaft assembly of the folding device, the electronic device achieves a good sealing and shielding effect in any of the unfolded, folded, or intermediate states, preventing dust from entering the folding device and causing movement jamming, or moisture from entering the internal components of the electronic device and causing damage. The folding device and electronic device of this application have high reliability and a long service life.

[0097] Please see Figure 1 and Figure 2 The embodiment shown in this application provides an electronic device 200. Wherein, Figure 1 This is a schematic diagram of the appearance of electronic device 200. Figure 2 This is a partially exploded view of the electronic device 200. The electronic device 200 includes the folding device 100 and the flexible display screen 210 involved in this application. The folding device 100 includes a first housing 110, a second housing 120, and a rotating mechanism 130. The first housing 110 and the second housing 120 are respectively fixedly connected to opposite sides of the rotating mechanism 130, together forming a support structure for the flexible display screen 210. This application embodiment uses an outward-folding screen structure for the electronic device 200 as an example for illustration.

[0098] The rotating mechanism 130 includes a main shaft assembly 30, a first transmission arm 10, and a second transmission arm 20 (see also...). Figure 4 The first transmission arm 10 is fixedly connected to the first housing 110, and the second transmission arm 20 is fixedly connected to the second housing 120. The flexible display screen 210 includes a first non-bending portion 211, a bending portion 213, and a second non-bending portion 212 arranged sequentially. The flexible display screen 210 is fixed to the folding device 100, which consists of the first housing 110, the second housing 120, and the rotating mechanism 130. For example, the flexible display screen 210 can be fixedly connected by adhesive bonding. The first non-bending portion 211 of the flexible display screen 210 is fixed to the first housing 110, the second non-bending portion 212 is fixed to the second housing 120, and the bending portion 213 corresponds to the position of the rotating mechanism 130 in the folding device 100.

[0099] The rotating mechanism 130 can deform to fold or unfold the first transmission arm 10 and the second transmission arm 20 relative to each other, thereby synchronously driving the first housing 110 and the second housing 120 to fold or unfold relative to each other. The flexible display screen 210 can be folded and unfolded synchronously with the folding device 100. Figure 1 and Figure 2 The illustrated electronic device 200 is in a state where the first housing 110 and the second housing 120 are relatively unfolded, and the flexible display screen 210 is also relatively flattened. For example, when the first housing 110 and the second housing 120 are in a relatively unfolded state along with the first transmission arm 10 and the second transmission arm 20, they can be approximately 180° apart (a slight deviation is also allowed, such as 165°, 177°, or 185°). In this state, the electronic device 200 can be defined as being in a flattened form. When the flexible display screen 210 is in a flattened state, it can display the entire screen, giving the electronic device 200 a larger display area and improving the user's viewing experience.

[0100] Please see Figure 3The first housing 110 and the second housing 120 can also fold relative to each other with the first transmission arm 10 and the second transmission arm 20 under the deformation action of the rotating mechanism 130. The first housing 110 and the second housing 120 can be completely closed to be parallel to each other (a slight deviation is also allowed). The folding device 100 also includes opposing inner surfaces B (see...). Figure 2 The outer side A is defined as the side used to support the flexible display screen 210. When the first housing 110 and the second housing 120 are folded together, the side where they meet is defined as the inner side B.

[0101] Please see here. Figure 3a Because the first non-bending portion 211 and the second non-bending portion 212 of the flexible display screen 210 are fixedly connected to the first housing 110 and the second housing 120 respectively, the flexible display screen 210 will also be in a roughly U-shaped structure as the folding device 100 folds relative to each other. Correspondingly, the electronic device 200 is also in a closed state due to the relative folding of the first housing 110 and the second housing 120.

[0102] For ease of explanation, Figure 3 The diagram only illustrates the folded state of the folding device 100. When the electronic device 200 is in the closed state, its planar dimensions are small (with a smaller width), making it easy for users to carry and store.

[0103] The electronic device 200 of this application can be a mobile phone, tablet computer, laptop computer, or other similar products. This embodiment uses a mobile phone as an example for illustration.

[0104] The flexible display screen 210 involved in this application can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen.

[0105] It is understood that this embodiment is illustrated using the example of "the rotation center of the electronic device 200 being parallel to the width direction of the electronic device 200". In this case, the electronic device 200 can rotate left and right, and the folding and unfolding of the electronic device 200 affects its width dimension. In some other embodiments, the rotation center of the electronic device 200 may also be parallel to its length direction. In this case, the electronic device 200 can rotate up and down, and the folding and unfolding of the electronic device 200 affects its length dimension.

[0106] Please see Figure 4 The schematic breakdown of the folding device 100.

[0107] As mentioned above, the folding device 100 includes a first housing 110, a second housing 120, and a rotating mechanism 130. The rotating mechanism 130 includes a main shaft assembly 30, a first transmission arm 10, and a second transmission arm 20. One end of the first transmission arm 10 is rotatably connected to the main shaft assembly 30, and the other end of the first transmission arm 10 is fixedly connected to the first housing 110. The second transmission arm 20 is located on the side of the main shaft assembly 30 opposite to the first transmission arm 10. One end of the second transmission arm 20 is rotatably connected to the main shaft assembly 30, and the other end of the second transmission arm 20 is fixedly connected to the second housing 120.

[0108] Specifically, both the first transmission arm 10 and the second transmission arm 20 are located on the outer surface A of the folding device 100. The first transmission arm 10 includes a first fixing part 103 (see [link to documentation]). Figure 29 The second transmission arm 20 includes a second fixing part 203 (see also...). Figure 29 The first fixing part 103 is used to fix the first fixing end 112 of the first housing 110 (see also...). Figure 29 The second fixing part 203 is used for a fixed connection with the second fixing end 122 of the second housing 120 (see [link]). Figure 29 The folding device 100 is fixedly connected. On the inner side B of the folding device 100, the rotating mechanism 130 also includes a first rotating arm 40 (see [link to documentation]). Figure 6 ), second rotating arm 50 (see Figure 6 ), first shielding member 60 and second shielding member 70.

[0109] Please see Figure 5 and Figure 6 A schematic diagram of the rotating mechanism 130 shown.

[0110] The first shielding member 60 and the first rotating arm 40 are both located on the side of the main shaft assembly 30 near the first transmission arm 10, while the second shielding member 70 and the second rotating arm 50 are located on the side of the main shaft assembly 30 near the second transmission arm 20. Specifically, the first shielding member 60 and the second shielding member 70 are both located on the inner side (position B) of the folding device 100; the first rotating arm 40 is located between the first shielding member 60 and the first transmission arm 10 and is fixedly connected to the first shielding member 60; the second rotating arm 50 is located between the second shielding member 70 and the second transmission arm 20 and is fixedly connected to the second shielding member 70.

[0111] Please refer to the above. Figure 7 The diagram shows the structure of the first rotating arm 40 and the second rotating arm 50.

[0112] The first rotating arm 40 includes two first rotating members 41 and two second rotating members 42, which are arranged at intervals along the length of the main shaft assembly 30. Further details can be found in the reference section. Figure 8 and Figure 9 The first rotating arm 40 further includes a first rotating end 401, which is distributed on each of the first rotating members 41 and the second rotating members 42. The first rotating end 401 is located on the side of the first rotating arm 40 closer to the spindle assembly 30. The first rotating arm 40 is rotatably connected to the spindle assembly 30 through the first rotating end 401. Specifically, the first rotating member 41 is rotatably connected to the spindle assembly 30 through the first rotating end 401 located near it, and the second rotating member 42 is rotatably connected to the spindle assembly 30 through the first rotating end 401 located near it.

[0113] The first rotating arm 40 further includes a first sliding end 402, which is located on the side of the first rotating arm 40 facing away from the main shaft assembly 30, and is also distributed on each of the first rotating members 41 and the second rotating member 42. The first rotating arm 40 is slidably connected to the first transmission arm 10 on the side facing away from the main shaft assembly 30 via the first sliding end 402. (See the detailed description in the following embodiments and figures.)

[0114] Through the aforementioned connection arrangement, the first rotating arm 40 can rotate relative to the main shaft assembly 30 and simultaneously slide relative to the first transmission arm 10. During the folding or unfolding process of the folding device 100, the first rotating arm 40 and the first transmission arm 10 are respectively rotatably connected to the main shaft assembly 30 and can rotate relative to the main shaft assembly 30. Because the first rotating arm 40 is closer to the inner surface B of the folding device 100 than the first transmission arm 10, its bending radius is smaller. The first rotating arm 40 can compensate for this difference in bending radius by sliding relative to the first transmission arm 10, achieving the effect of synchronous rotation with the first transmission arm 10.

[0115] The first rotating member 41 and the second rotating member 42 are arranged at intervals along the length of the main spindle assembly 30, increasing the rotational connection fulcrum between the first rotating arm 40 and the main spindle assembly 30. This ensures that the first rotating arm 40 maintains a stable relative position with the main spindle assembly 30 along its length during rotation, resulting in relatively smooth rotation of the entire first rotating arm 40. It is understood that in other embodiments, the number of the first rotating member 41 and the second rotating member 42 in the first rotating arm 40 can be set to other values, and the arrangement of the first rotating member 41 and the second rotating member 42 can also differ from the arrangement shown in the figure without affecting the rotational movement between the first rotating arm 40 and the main spindle assembly 30.

[0116] Please see back Figure 7 And see also Figure 10 and Figure 11 The second rotating arm 50 includes two third rotating members 51 and two fourth rotating members 52, which are also spaced apart along the length of the main spindle assembly 30. The second rotating arm 50 also includes a second rotating end 501, which is distributed on each of the third rotating members 51 and fourth rotating members 52, and is located on the side of the second rotating arm 50 closer to the main spindle assembly 30. The second rotating arm 50 is rotatably connected to the main spindle assembly 30 via the second rotating end 501. Specifically, the third rotating members 51 are rotatably connected to the main spindle assembly 30 via the second rotating end 501 located near them, and the fourth rotating members 52 are rotatably connected to the main spindle assembly 30 via the second rotating end 501 located near them.

[0117] The second rotating arm 50 also includes a second sliding end 502, which is located on the side of the second rotating arm 50 facing away from the main shaft assembly 30, and is also distributed on each of the third rotating members 51 and the fourth rotating member 52. The second rotating arm 50 is slidably connected to the second transmission arm 20 on the side facing away from the main shaft assembly 30 via the second sliding end 502. (See the detailed description in the following embodiments and accompanying drawings.)

[0118] Through the aforementioned connection arrangement, the second rotating arm 50 can also rotate relative to the main shaft assembly 30 and simultaneously slide relative to the second transmission arm 20. Similarly, because the second rotating arm 50 is closer to the inner side B of the folding device 100 than the second transmission arm 20, the second rotating arm 50 can also compensate for the difference in bending radius by sliding relative to the second transmission arm 20, achieving the effect of rotating synchronously with the second transmission arm 20.

[0119] Similarly, the third rotating member 51 and the fourth rotating member 52 are arranged at intervals along the length of the main shaft assembly 30, which also increases the rotational connection fulcrum between the second rotating arm 50 and the main shaft assembly 30, ensuring that the rotational movement of the second rotating arm 50 is relatively smooth. In other embodiments, the number and arrangement of the third rotating member 51 and the fourth rotating member 52 in the second rotating arm 50 can also be set differently without affecting the rotational movement between the second rotating arm 50 and the main shaft assembly 30.

[0120] Please see Figure 12 The diagram shows the structure of the first transmission arm 10 and the second transmission arm 20.

[0121] The first transmission arm 10 is provided with a plurality of first rotating parts 101 and a plurality of first sliding parts 102. The plurality of first rotating parts 101 are arranged along the length direction of the first transmission arm 10, that is, the plurality of first rotating parts 101 are spaced apart along the length direction of the main shaft assembly 30. Each first rotating part 101 is rotatably connected to the main shaft assembly 30 (see [link]). Figure 13 and Figure 14 (Illustrative diagram). It is understandable that the multiple first rotating parts 101, spaced apart along the length of the first transmission arm 10, can form multiple fulcrums with the main shaft assembly 30, thereby maintaining the smoothness of the first transmission arm 10's movement during rotation relative to the main shaft assembly 30. On the other hand, the rotation center formed by each first rotating part 101 and the main shaft assembly 30 is different from the rotation center formed by the first rotating end 401 of the first rotating arm 40 and the main shaft assembly 30. Because of the difference in bending radii between the first transmission arm 10 and the first rotating arm 40, their rotation centers also need to be differentiated to achieve synchronous rotation between the first transmission arm 10 and the first rotating arm 40.

[0122] The plurality of first sliding portions 102 of the first transmission arm 10 are also spaced apart along the length direction of the first transmission arm 10, that is, the plurality of first sliding portions 102 are spaced apart along the length direction of the main shaft assembly 30. Please refer to [link to details] for more information. Figure 15 Each first sliding part 102 can be constructed as two opposite first slide rails 102a and 102b, and the position of each first sliding part 102 corresponds to the position of the first rotating member 41 or the second rotating member 42 of the first rotating arm 40.

[0123] Please refer to the above. Figure 16 The first sliding end 402 disposed on the first rotating member 41 is constructed as two opposing first sliding grooves 402a and 402b, one of which is fitted onto a first slide rail 102a, and the other is fitted onto a first slide rail 102b. Thus, the first sliding grooves 402a and 402b can slide relative to the first slide rails 102a and 102b respectively, thereby allowing the first sliding end 402 on the first rotating member 41 to slide relative to a first sliding portion 102; while... Figure 17 On the second rotating member 42 shown, the first sliding end 402 of the second rotating member 42 is constructed as a single first sliding groove 402a, one of which is fitted onto the first slide rail 102a of the other first sliding part 102, while the other first sliding groove 402b is unused. Thus, the first sliding end 402 on the second rotating member 42 can also slide relative to one of the first sliding parts 102. It is understood that the unused first sliding groove 402b can also be fitted onto a first slide rail 102b.

[0124] Through the above configuration, a sliding connection between the first rotating arm 40 and the first transmission arm 10 is achieved. Furthermore, the sliding connection between the multiple first sliding ends 402 and the multiple first sliding portions 102 ensures smooth sliding of the first rotating arm 40 relative to the first transmission arm 10. It is understood that the first sliding ends 402 can also be constructed as slide rails, corresponding to the first sliding portions 102 being constructed as grooves. In some embodiments, the first sliding ends 402 simultaneously include slide rails and grooves, corresponding to the first sliding portions 102 simultaneously including grooves and slide rails. The sliding connection between the first rotating arm 40 and the first transmission arm 10 can still be achieved through the cooperation of the slide rail and groove structure.

[0125] Please see back Figure 12 The second transmission arm 20 is provided with multiple second rotating parts 201 and multiple second sliding parts 202. The multiple second rotating parts 201 are arranged along the length direction of the second transmission arm 20, that is, the multiple second rotating parts 201 are spaced apart along the length direction of the main shaft assembly 30. Each second rotating part 201 is rotatably connected to the main shaft assembly 30 (see [link to documentation]). Figure 18 and Figure 19 (Illustrative diagram). Multiple second rotating parts 201, spaced apart along the length of the second transmission arm 20, can also form multiple fulcrums with the main shaft assembly 30, thereby maintaining the smoothness of the second transmission arm 20's movement during rotation relative to the main shaft assembly 30. Furthermore, the rotation center formed by each second rotating part 201 and the main shaft assembly 30 is distinct from the rotation center formed by the second rotating end 501 of the second rotating arm 50 and the main shaft assembly 30, ensuring that the second transmission arm 20 and the second rotating arm 50 rotate synchronously.

[0126] The plurality of second sliding portions 202 of the second transmission arm 20 are also spaced apart along the length direction of the second transmission arm 20, that is, the plurality of second sliding portions 202 are spaced apart along the length direction of the main shaft assembly 30. Please refer to [link to details] for more information. Figure 20 Each second sliding part 202 can be constructed as two opposing second slide rails 202a and 202b, and the position of each second sliding part 202 corresponds to the position of the third rotating member 51 or the fourth rotating member 52 of the second rotating arm 50.

[0127] Please refer to the above. Figure 21 The second sliding end 502 disposed on the third rotating member 51 is constructed as two opposing second sliding grooves 502a and 502b, one second sliding groove 502a being fitted onto a second slide rail 202a, and the other second sliding groove 502b being fitted onto a second slide rail 202b. Thus, the second sliding grooves 502a and 502b can slide relative to the second slide rails 202a and 202b respectively, thereby allowing the second sliding end 502 on the third rotating member 51 to slide relative to a second sliding portion 202; while... Figure 22 On the fourth rotating member 52 shown, the second sliding end 502 of the fourth rotating member 52 is also constructed as two opposing second sliding grooves 502a and 502b. One second sliding groove 502a is fitted onto the second slide rail 202a of the other second sliding part 202, while the other second sliding groove 502b is left unused. Therefore, the second sliding end 502 on the fourth rotating member 52 can also slide relative to one of the second sliding parts 202. It is understandable that the unused second sliding groove 502b can also be fitted onto one of the second slide rails 202b.

[0128] Through the above configuration, a sliding connection between the second rotating arm 50 and the second transmission arm 20 is achieved. Furthermore, the sliding connection between the multiple second sliding ends 502 and the multiple second sliding portions 202 ensures smooth sliding of the second rotating arm 50 relative to the second transmission arm 20. It is understood that the second sliding ends 502 can also be constructed as slide rails, corresponding to the second sliding portions 202 being constructed as grooves. In some embodiments, the second sliding ends 502 simultaneously include slide rails and grooves, corresponding to the second sliding portions 202 simultaneously including grooves and slide rails. The sliding connection between the second rotating arm 50 and the second transmission arm 20 can still be achieved through the cooperation of the slide rail and groove structure.

[0129] Please see Figure 23 The diagram shows the structure of the first shielding member 60 and the second shielding member 70.

[0130] The first shielding member 60 is fixed to the first sliding end 402 of the first rotating arm 40, and the second shielding member 70 is fixed to the second sliding end 502 of the second rotating arm 50. The first shielding member 60 includes a first fixing member 61 and a first cover plate 62. The first fixing member 61 is used to fix to the first sliding end 402. Specifically, there are multiple first fixing members 61, which are used to fix to one first rotating member 41 and / or one second rotating member 42, and are located on the side of the first rotating member 41 and / or the second rotating member 42 respectively close to the first sliding end 402, so as to achieve positional fixation between each first fixing member 61 and the first sliding end 402.

[0131] Please see Figure 24 and Figure 25 In this embodiment, the first fixing member 61 is provided with a plurality of first positioning holes 611, and the first rotating arm 40 is provided with a plurality of first positioning posts 403. The first positioning posts 403 are also distributed on each of the first rotating members 41 and the second rotating members 42. The position of each first positioning post 403 corresponds to the position of a first positioning hole 611, so that the first fixing member 61 can be fitted and fixed on the first rotating arm 40. Because each of the first rotating members 41 and the second rotating members 42 is arranged along the length direction of the main shaft assembly 30, the first positioning posts 403 are also arranged along the length direction of the main shaft assembly 30. The first fixing member 61 can form a plurality of mutually cooperating fixed support points with the first rotating arm 40 along the length direction of the main shaft assembly 30. When the first rotating arm 40 rotates relative to the main shaft assembly 30, the first fixing member 61 rotates synchronously with the first rotating arm 40, and the rotation of the first fixing member 61 relative to the main shaft assembly 30 is relatively smooth.

[0132] On the other hand, in the illustrated embodiment, there are two first fixing members 61, which are arranged at intervals along the length of the main shaft assembly 30, and each first positioning hole 611 is distributed on the two first fixing members 61. Compared with the embodiment in which multiple first positioning holes 611 are formed on a single, longer first fixing member 61, the structure of multiple first fixing members 61 is beneficial to ensuring the positional accuracy of the first positioning holes 611 on each first fixing member 61, reducing the machining accuracy of each first fixing member 61, controlling the cost of the first fixing members 61, and ensuring the positional accuracy of each first fixing member 61 when assembled on the first rotating arm 40. It is understood that in other embodiments, the number of first fixing members 61 may be more than two, which can be specifically set based on the overall length and structural requirements of the folding device 100.

[0133] Please see back Figure 23 The first cover plate 62 is elongated, with its length aligned with the length of the main shaft assembly 30. The first cover plate 62 is also fixedly connected to each of the first fixing members 61 and is located on the side of each first fixing member 61 facing away from the first rotating arm 40. That is, the first cover plate 62 is located near the inner surface B of the folding device 100. The first cover plate 62 is exposed on the folding device 100 and forms part of the inner surface B of the folding device. The first cover plate 62 is used to shield the internal components of the rotating mechanism 130 to prevent external moisture or impurities from entering the rotating mechanism 130 and causing the folding device 100 to jam.

[0134] On the other side of the spindle assembly 30, the second shielding member 70 includes a second fixing member 71 and a second cover plate 72. The second fixing member 71 is used to fix with the second sliding end 502. Specifically, there are multiple second fixing members 71, which are used to fix with a third rotating member 51 and / or a fourth rotating member 52, and are located on the side of the third rotating member 51 and / or the fourth rotating member 52 respectively close to the second sliding end 502, so as to achieve the position fixation between each second fixing member 71 and the second sliding end 502.

[0135] Please see Figure 26 and Figure 27The second fixing member 71 is also provided with multiple second positioning holes 711, and the second rotating arm 50 is provided with multiple second positioning posts 503. The second positioning posts 503 are also distributed on each of the third rotating members 51 and the fourth rotating member 52. The position of each second positioning post 503 corresponds to the position of a second positioning hole 711, so that the second fixing member 71 can be sleeved and fixed on the second rotating arm 50. The second positioning posts 503 are also arranged along the length direction of the main shaft assembly 30, forming multiple mutually cooperating fixed support points with the second rotating arm 50. When the second rotating arm 50 rotates relative to the main shaft assembly 30, the second fixing member 71 also rotates synchronously with the second rotating arm 50, and the rotation movement relative to the main shaft assembly 30 is relatively smooth.

[0136] On the other hand, in the illustrated embodiment, there are also two second fixing members 71, which are arranged at intervals along the length of the spindle assembly 30, and the second positioning holes 711 are distributed on the two second fixing members 71. The structure of providing multiple second fixing members 71 also helps to ensure the positional accuracy of the second positioning holes 711 on each second fixing member 71, reduces the machining accuracy of each second fixing member 71 and controls costs, while also ensuring the positional accuracy of each second fixing member 71 assembled on the second rotating arm 50. It is understood that in other embodiments, the number of second fixing members 71 may also be more than two.

[0137] The second cover plate 72 is also elongated, with its length arranged along the length of the main shaft assembly 30. The second cover plate 72 is also fixedly connected to each of the second fixing members 71 and is located on the side of each second fixing member 71 facing away from the second rotating arm 50. The second cover plate 72 is also exposed on the folding device 100 and forms part of the inner side B of the folding device. The second cover plate 72 can also be used to shield the internal components of the rotating mechanism 130 to prevent external moisture or impurities from entering the rotating mechanism 130 and causing the folding device 100 to jam.

[0138] Please see back Figure 4 And see also Figure 28 and Figure 29 .in Figure 28The diagram illustrates the structure of the folding device 100 in its unfolded state. On the inner side B of the folding device 100, the height of the rotating mechanism 130 is lower than the height of the first housing 110 and the second housing 120. Furthermore, the first shielding member 60 and the second shielding member 70 are located on the outermost side of the rotating mechanism 130 facing the inner side B; that is, the first shielding member 60 and the second shielding member 70 are constructed as the inner side B of the rotating mechanism 130. At this time, the height of the first shielding member 60 and the second shielding member 70 is lower than the height of the first housing 110 and the second housing 120, respectively. Further, the first housing 110 has a first receiving cavity 111 on the side near the rotating mechanism 130, and the second housing 120 has a second receiving cavity 121 on the side near the rotating mechanism 130. The first receiving cavity 111 is used to receive the first shielding member 60, and the second receiving cavity 121 is used to receive the second shielding member 70.

[0139] For details, please see Figure 30 When the folding device 100 is folded from the unfolded state to the folded state, the first rotating arm 40 and the second rotating arm 50 slide relative to the first transmission arm 10 and the second transmission arm 20, respectively. The sliding direction of the first rotating arm 40 is towards the first housing 110, and the sliding direction of the second rotating arm 50 is towards the second housing 120. Consequently, the first shielding member 60 and the second shielding member 70, which are fixedly connected to the first rotating arm 40 and the second rotating arm 50, respectively, slide towards the first housing 110 and the second housing 120, respectively, along with the first rotating arm 40 and the second rotating arm 50. Furthermore, the first shielding member 60 partially slides into the first receiving cavity 111 of the first housing 110, and the second shielding member 70 partially slides into the second receiving cavity 121 of the second housing 120.

[0140] Understandably, when the folding device 100 is opened from the folded state to the unfolded state, the first shielding member 60 and the second shielding member 70 slide towards the main shaft assembly 30 respectively. When the folding device 100 is in the unfolded state, the first shielding member 60 and the second shielding member 70 can move closer to each other to provide shielding protection for the main shaft assembly 30, the first rotating arm 40, the second rotating arm 50, the first transmission arm 10, and the second transmission arm 20. Thus, the first shielding member 60 and the second shielding member 70 can prevent external moisture or dust from entering the interior of the rotating mechanism 130, while simultaneously improving the appearance of the folding device 100.

[0141] It is understandable that the appearance of the first shielding member 60 and the second shielding member 70 can be matched with the appearance of the first housing 110 and the second housing 120, so that the appearance of the folding device 100 at the inner side B is consistent. In this embodiment, the appearance of the folding device 100 may include color, brightness, and texture. By setting the first shielding member 60 and the second shielding member 70 to use the same baking paint, coating process, and surface treatment process as the first housing 110 and the second housing 120, the appearance consistency at the inner side B can be improved. It is understandable that when the shape and material of the first shielding member 60, the second shielding member 70, the first housing 110, and the second housing 120 are further unified, the overall appearance consistency of the folding device 100 can be further guaranteed.

[0142] Through the aforementioned mechanism of the rotating mechanism 130, when the folding device 100 is in the unfolded state, the first shielding member 60 and the second shielding member 70 provide a shielding effect for the rotating mechanism 130. In one embodiment, the gap width between the first shielding member 60 and the second shielding member 70 can be less than or equal to 0.1 mm when the folding device 100 is in the unfolded state, to ensure its protective effect on the rotating mechanism 130. Furthermore, in this application, the folding device 100 directly fixes the first shielding member 60 to the first rotating arm 40 and the second shielding member 70 directly to the second rotating arm 50, so that the first shielding member 60 and the second shielding member 70 move synchronously with the first rotating arm 40 and the second rotating arm 50, respectively. Their movement trajectory is relatively simple, and the structure of the rotating mechanism 130 is also relatively simple, which can reduce the overall volume of the rotating mechanism 130 and reduce the manufacturing cost of the folding device 100.

[0143] Meanwhile, existing shielding solutions are typically complex in structure, and maintenance usually requires disassembling the internal components of the rotating mechanism 130, which is relatively difficult. In contrast, the folding device 100 of this application is fixed between the first shielding member 60 and the first rotating arm 40, and between the second shielding member 70 and the second rotating arm 50, respectively, through a first positioning hole 611 and a first positioning post 403, and through a second positioning hole 711 and a second positioning post 503. This facilitates the connection and disassembly of the first shielding member 60 and the second shielding member 70 on the rotating mechanism 130. It is understood that when the first shielding member 60 and / or the second shielding member 70 in the folding mechanism 100 are accidentally damaged, they can be directly removed and replaced from the inner side B of the folding device 100.

[0144] In some embodiments, the first fixing member 61 and the first cover plate 62 within the first shielding member 60 are bonded together with adhesive, and the second fixing member 71 and the second cover plate 72 within the second shielding member 70 are also bonded together with adhesive. When the first cover plate 62 and / or the second cover plate 72 are damaged, the first cover plate 62 and / or the second cover plate 72 can be locally heated until the adhesive melts, and then the first cover plate 62 and / or the second cover plate 72 can be directly removed and replaced.

[0145] Please refer to one embodiment. Figure 31 and Figure 32 The rotating mechanism 130 of this application further includes a first engaging member 81 and a second engaging member 82. Along the direction from the first housing 110 to the second housing 120, the first engaging member 81 and the second engaging member 82 are symmetrically arranged with respect to the center of the main shaft assembly 30 and extend toward the first housing 110 and the second housing 120, respectively. The first engaging member 81 is located closer to the first housing 110, and the second engaging member 82 is located closer to the second housing 120.

[0146] Along the direction from the outer side A to the inner side B of the folding device 100, the first engaging member 81 is located between the first transmission arm 10 and the first shielding member 60, and the second engaging member 82 is located between the second transmission arm 20 and the second shielding member 70. Thus, the first shielding member 60 and the second shielding member 70 also provide a shielding effect for the first engaging member 81 and the second engaging member 82. Furthermore, along the length of the main shaft assembly 30, there are multiple first engaging members 81 and multiple second engaging members 82, and each first engaging member 81 is paired with one second engaging member 82.

[0147] For details, please refer to the following: Figure 33 The first engaging member 81 includes a first engaging end 811 and a third sliding end 812, and the second engaging member 82 includes a second engaging end 821 and a fourth sliding end 822, both opposite to each other. In the paired first engaging member 81 and second engaging member 82, the first engaging end 811 and the second engaging end 821 are located relatively close to each other, while the third sliding end 812 and the fourth sliding end 822 extend in opposite directions. The first engaging end 811 and the second engaging end 821 are respectively provided with engaging teeth, and the first engaging end 811 and the second engaging end 821 mesh with each other through the structure of the engaging teeth. The rotational movement of the first engaging member 81 can be transmitted to the second engaging member 82 through meshing, causing the second engaging member 82 to rotate synchronously; conversely, the rotational movement of the second engaging member 82 can also cause the first engaging member 81 to rotate synchronously through meshing.

[0148] The third sliding end 812 of the first engaging member 81 is slidably connected to the first transmission arm 10. For details, please refer to [link to relevant documentation]. Figure 34In this embodiment, the third sliding end 812 is constructed as a third slide rail 812a, and the first transmission arm 10 is provided with a third slide groove 104a corresponding to the position of the third sliding end 812. The shape of the third slide groove 104a matches that of the third slide rail 812a, so that the third sliding end 812 can slide relative to the first transmission arm 10; correspondingly, please refer to Figure 35 The fourth sliding end 822 of the second engaging member 82 is slidably connected to the second transmission arm 20. The fourth sliding end 822 is constructed as a fourth slide rail 822a, and the second transmission arm 20 is provided with a fourth slide groove 204a corresponding to the position of the fourth sliding end 822. The shape of the fourth slide groove 204a matches that of the fourth slide rail 822a, so that the fourth sliding end 822 can slide relative to the second transmission arm 20.

[0149] Therefore, during the folding or unfolding process of the folding device 100 of this application, when the user drives either the first housing 110 or the second housing 120 to rotate, the first engaging member 81 and the second engaging member 82 can make the first housing 110 and the second housing 120 rotate synchronously, thereby reducing the rotational stroke of the user manually flipping the folding device 100. It can be understood that when the unfolded state of the folding device 100 is 180 degrees, the user only needs to operate the first housing 110 or the second housing 120 to rotate 90 degrees to complete the action of switching the folding device 100 from the folded state to the unfolded state, improving the user experience. At the same time, the first engaging member 81 and the second engaging member 82 are slidably connected relative to the first transmission arm 10 and the second transmission arm 20, respectively, which also ensures the smooth rotation of the first engaging member 81 and the second engaging member 82 within the rotating mechanism 130.

[0150] Please refer to one embodiment. Figure 36 and Figure 37 . Figure 36 The diagram illustrates the disassembled structure of the first transmission component 41. Figure 37 The exploded structure of the third transmission component 51 is shown.

[0151] exist Figure 36In the schematic diagram, the first transmission component 41 includes a plurality of first springs 411 and a first spring shaft 412 for fixing each of the first springs 411. The first spring shaft 412 is arranged along the direction from the first rotating end 401 to the first sliding end 402. Each of the first springs 411 is sleeved on a first spring shaft 412, so that each of the first springs 411 abuts against the first rotating end 401 and the first sliding end 402. The first springs 411 are used to provide elastic force to push the first rotating end 401 away from the first sliding end 402. The first springs 411 can form a damping effect on the first rotating arm 40, so that when the folding device 100 is in the unfolded state, a certain external force is required to overcome the damping force of the first springs 411 before the first rotating arm 40 can be driven to rotate around the first rotating end 401 relative to the main shaft assembly 30.

[0152] exist Figure 37 In the schematic diagram, the third transmission component 51 includes a plurality of second springs 511 and a second spring shaft 512 for fixing each second spring 511. The second spring shaft 512 is arranged along the direction from the second rotating end 501 to the second sliding end 502. Each second spring 511 is sleeved on a second spring shaft 512 so that each second spring 511 abuts against the second rotating end 501 and the second sliding end 502. The second springs 511 also provide a spring force to push the second rotating end 501 away from the second sliding end 502. The second springs 511 can form a damping effect on the second rotating arm 50, so that when the folding device 100 is in the unfolded state, a certain external force is required to overcome the damping force of the second springs 511 before the second rotating arm 50 can be driven to rotate around the second rotating end 501 relative to the main shaft assembly 30.

[0153] Therefore, through the combined action of the first spring 411 and the second spring 511, the folding device 100 of this application can maintain its relative stability in the unfolded state, and will not easily flip towards the folded state when subjected to external force, thereby ensuring that the user can continue to use the electronic device 200 of this application in the unfolded state. That is, the first spring 411 and the second spring 511 can work together to keep the electronic device 200 in a stable posture.

[0154] Please refer to one embodiment. Figure 38 and Figure 39The spindle assembly 30 of this application includes a central spindle plate 33, a first side spindle plate 31, and a second side spindle plate 32. The first side spindle plate 31 and the second side spindle plate 32 are positioned on opposite sides of the central spindle plate 33, with the first side spindle plate 31 located between the central spindle plate 33 and the first transmission arm 10, and the second side spindle plate 32 located between the central spindle plate 33 and the second transmission arm 20. Furthermore, the first side spindle plate 31 and the second side spindle plate 32 are rotatably connected to the central spindle plate 33, and the side of the first side spindle plate 31 facing away from the central spindle plate 33 is also rotatably connected to the first transmission arm 10, while the side of the second side spindle plate 32 facing away from the central spindle plate 33 is also rotatably connected to the second transmission arm 20.

[0155] Therefore, when the folding device 100 of this application is in the folded state, the first side shaft plate 31 and the second side shaft plate 32 also rotate relative to the central shaft plate 33, and are respectively connected between the central shaft plate 33 and the first transmission arm 10, and between the central shaft plate 33 and the second transmission arm 20. The arrangement of the first side shaft plate 31 and the second side shaft plate 32 increases the bending radius of the main shaft assembly 30, and thus accommodates the outer thickness of the first housing 110 and the second housing 120 when they are folded relative to each other, so that the folding device 100 can provide a relatively flat outer surface A when folded. At this time, the outer surface A is U-shaped, which can better support the flexible display screen 210.

[0156] Please refer to one embodiment. Figure 40 The central shaft plate 33 includes a central inner plate 331 and a central outer plate 332. The central outer plate 332 is located near the inner side B, and the central inner plate 331 is located near the outer side A. The central outer plate 332 is fastened to the central inner plate 331, and the two are fixedly connected to form a structure with multiple arc-shaped grooves. Furthermore, the central shaft plate 33 includes opposing first side 3301 and second side 3302. The first side 3301 is close to the first side shaft plate 31, and the second side 3302 is close to the second side shaft plate 32.

[0157] exist Figure 40 In the illustration, the central spindle plate 33 is further divided into three sections along the length of the spindle assembly 30. The inner central plate 331 and the outer central plate 332 are each divided into three sections (the outer central plate 332 is further divided into three smaller sections in the middle section). Each inner central plate 331 and each outer central plate 332 are fixed together. The three sections are then joined end to end to form the central spindle plate 33. Dividing the central spindle plate 33 into multiple sections ensures the machining accuracy of the inner central plate 331 and the outer central plate 332 in each section, thereby ensuring the overall accuracy of the central spindle plate 33 after joining end to end.

[0158] Please see Figure 41At the first side 3301, the central shaft plate 33 forms multiple first arc-shaped grooves 91 through the cooperation of the inner central plate 331 and the outer central plate 332. Correspondingly, multiple first arc-shaped slide rails 311 are provided on the first side shaft plate 31 at the positions of each first arc-shaped groove 91. Each first arc-shaped slide rail 311 extends into a first arc-shaped groove 91 to achieve a rotational connection between the first side shaft plate 31 and the central shaft plate 33. This structure, employing the cooperation of the first arc-shaped slide rails 311 and the first arc-shaped grooves 91, achieves a rotational connection while also compressing the overall thickness of the main shaft assembly 30. It is understood that in other embodiments, the first side shaft plate 31 and the central shaft plate 33 can also achieve a rotational connection through a shaft-hole cooperation structure.

[0159] And in Figure 42 At the second side 3302 shown, the central shaft plate 33 forms multiple second arc-shaped grooves 92 through the cooperation of the central inner plate 331 and the central outer plate 332. Correspondingly, multiple second arc-shaped slide rails 321 are provided on the second side shaft plate 32 at the positions of each second arc-shaped groove 92. Each second arc-shaped slide rail 321 also extends into a second arc-shaped groove 92 to achieve a rotational connection between the second side shaft plate 32 and the central shaft plate 33. It is understood that in other embodiments, the second side shaft plate 32 and the central shaft plate 33 can also achieve a rotational connection through a structure of a rotating shaft and a shaft hole.

[0160] On the side of the first side shaft plate 31 and the first transmission arm 10, please refer to Figure 43 The diagram illustrates the first transmission arm 10, which includes a third side 105 near the first side shaft plate 31. The first transmission arm 10 has multiple third arc-shaped grooves 93 formed on the third side 105. For details, please refer to [reference needed]. Figure 44 The first transmission arm 10 includes a first transmission inner plate 11 and a first transmission outer plate 12. The first transmission inner plate 11 and the first transmission outer plate 12 are fixedly connected to each other to form the aforementioned plurality of third arc-shaped grooves 93. It can be understood that the third arc-shaped groove 93 here is the first rotating part 101 of the first transmission arm 10. That is, in this embodiment, the first rotating part 101 of the first transmission arm 10 is constructed in the shape of the third arc-shaped groove 93. In order to ensure the dimensional accuracy of each third arc-shaped groove 93, the first transmission outer plate 12 is also divided into multiple parts, and each first transmission outer plate 12, when fixed on the first transmission inner plate 11, forms a third arc-shaped groove 93.

[0161] Correspondingly, the first side shaft plate 31 is provided with multiple third arc-shaped slide rails 312 corresponding to the positions of each third arc-shaped groove 93. Each third arc-shaped slide rail 312 extends into a third arc-shaped groove 93 to realize the rotational connection between the first side shaft plate 31 and the first transmission arm 10.

[0162] Please see Figure 45 As illustrated, on the side of the second side shaft plate 32 and the second transmission arm 20, the second transmission arm 20 includes a fourth side edge 205 near the second side shaft plate 32. Furthermore, the second transmission arm 20 has multiple fourth arc-shaped grooves 94 formed on the fourth side edge 205. For details, please refer to [reference needed]. Figure 46 The second transmission arm 20 includes a second transmission inner plate 21 and a second transmission outer plate 22. The second transmission inner plate 21 and the second transmission outer plate 22 are fixedly connected to each other to form the aforementioned plurality of fourth arc-shaped grooves 94. It can be understood that the fourth arc-shaped groove 94 here is the second rotating part 201 of the second transmission arm 20. That is, in this embodiment, the second rotating part 201 of the second transmission arm 20 is constructed in the shape of a fourth arc-shaped groove 94. Furthermore, to ensure the dimensional accuracy of each fourth arc-shaped groove 94, the second transmission outer plate 22 is also divided into multiple sections, each forming a fourth arc-shaped groove 94 when fixed to the second transmission inner plate 21.

[0163] Correspondingly, the second side shaft plate 32 is provided with multiple fourth arc-shaped slide rails 322 corresponding to the positions of each fourth arc-shaped groove 94. Each fourth arc-shaped slide rail 322 is located in a fourth arc-shaped groove 94 to realize the rotational connection between the second side shaft plate 32 and the second transmission arm 20.

[0164] Similar to the reasons mentioned above, the cooperation between the third arc-shaped groove 93 and the third arc-shaped slide rail 312, and the cooperation between the fourth arc-shaped groove 94 and the fourth arc-shaped slide rail 322, can also reduce the overall thickness of the main shaft assembly 30. Furthermore, the rotational connection between the first side shaft plate 31 and the first transmission arm 10, and between the second side shaft plate 32 and the second transmission arm 20, can also be achieved using a shaft-hole coupling structure.

[0165] Please refer to one embodiment. Figure 47 and Figure 48 The first rotating arm 40 and the second rotating arm 50 are respectively rotatably connected to the central shaft plate 33 to form a rotatable connection between the first rotating arm 40 and the second rotating arm 50 and the main shaft assembly 30. Specifically, as mentioned above, the central outer plate 332 is fastened to the central inner plate 331, and the two are fixedly connected, forming a structure with multiple arc-shaped grooves in the central shaft plate 33. This structure of the arc-shaped grooves can also be used to realize the rotatable connection between the central shaft plate 33 and the first rotating arm 40 and the second rotating arm 50 respectively.

[0166] Please see Figure 49 The first side 3301 of the central shaft plate 33 also includes a plurality of fifth arc-shaped grooves 95, corresponding to the construction of a plurality of fifth arc-shaped slide rails for each first rotating end 401 of the first rotating arm 40. Each fifth arc-shaped slide rail extends into a fifth arc-shaped groove 95 to form a rotational connection between the first rotating end 401 and the central shaft plate 33; while Figure 50In the schematic diagram, the second side 3302 of the central shaft plate 33 also includes a plurality of sixth arc-shaped grooves 96, corresponding to the construction of a plurality of sixth arc-shaped slide rails for each of the second rotating ends 501 of the second rotating arm 50. Each sixth arc-shaped slide rail extends into a sixth arc-shaped groove 96 to form a rotational connection between the second rotating end 501 and the central shaft plate 33.

[0167] Understandably, the connection methods between the fifth arc-shaped groove 95 and the fifth arc-shaped slide rail, and between the sixth arc-shaped groove 96 and the sixth arc-shaped slide rail, can also compress the overall thickness of the main spindle assembly 30. Furthermore, in some embodiments, the first rotating arm 40 and the second rotating arm 50 can also be rotatably connected to the central shaft plate 33 via a shaft-fitting hole structure.

[0168] On the other hand, the mating structure between the aforementioned arc-shaped grooves and arc-shaped slide rails can also allow the positions of the arc-shaped grooves and arc-shaped slide rails to be interchanged. For example, a structure in which multiple fifth arc-shaped slide rails are provided on the first side 3301 of the central shaft plate 33, and the first rotating end 401 is constructed as a fifth arc-shaped groove 95, can also realize the rotational connection between the aforementioned components. This application does not make any special limitation here, and the specific configuration and adjustment can be based on the internal structure of the rotating mechanism 130.

[0169] In the above embodiments, the rotation axes of the rotational connections between the various components are positioned differently. Furthermore, based on the differences in bending radii among the components during the folding process of the folding device 100, the distances between the rotation axes of each rotational connection and the geometric center of the central shaft plate 33 are also different.

[0170] For example, the rotation axis between the first side shaft plate 31 and the first transmission arm 10, and the rotation axis between the second side shaft plate 32 and the second transmission arm 20, are equidistant from the geometric center of the central shaft plate 33, and are relatively larger than the distances between the rotation axes between the first side shaft plate 31 and the central shaft plate 33, and between the second side shaft plate 32 and the central shaft plate 33. Alternatively, the rotation axis between the first side shaft plate 31 and the central shaft plate 33, and the rotation axis between the second side shaft plate 32 and the central shaft plate 33, are located between the rotation axes of the first side shaft plate 31 and the first transmission arm 10, and the rotation axes of the second side shaft plate 32 and the second transmission arm 20. In this case, the bending radius of the first transmission arm 10 and the second transmission arm 20 is larger than the rotation radius of the first side shaft plate 31 and the second side shaft plate 32, and the rotation angle is also larger.

[0171] The rotation axes between the first rotating arm 40 and the central shaft plate 33, and between the second rotating arm 50 and the central shaft plate 33, are located between the rotation axes between the first side shaft plate 31 and the central shaft plate 33, and between the rotation axes between the second side shaft plate 32 and the central shaft plate 33. At this time, the rotation radii of the first rotating arm 40 and the second rotating arm 50 are smaller than those of the first side shaft plate 31 and the second side shaft plate 32. Furthermore, the rotation axis between the first rotating arm 40 and the central shaft plate 33 is located closer to the first transmission arm 10, while the corresponding rotation axis between the second rotating arm 50 and the central shaft plate 33 is located closer to the second transmission arm 20.

[0172] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application, such as reducing or adding structural components, changing the shape of structural components, etc., should all be covered within the scope of protection of this application. Where there is no conflict, the embodiments and features in the embodiments of this application can be combined with each other. Therefore, the scope of protection of this application should be determined by the scope of the claims.
