Description

Technical Field

[0001] This invention relates to the field of screen support, and more particularly to a folding device, a folding housing, and an electronic device. Background Technology

[0002] With the development of display devices, bendable screens have emerged, and electronic devices with bendable screens are becoming increasingly popular. However, when the folding mechanism in these electronic devices drives the bendable screen, the folding mechanism has limitations in mitigating the bending stress of the screen. This can lead to the screen experiencing excessive bending stress during bending, making it prone to damage. Summary of the Invention

[0003] In a first aspect, embodiments of this application provide a folding device, the folding device comprising:

[0004] Support assembly, the support assembly including a first support member and a second support member; and

[0005] A rotating assembly, comprising a main body and a first rotating mechanism and a second rotating mechanism connected to the main body, wherein the first rotating mechanism comprises a first rotating component, a second rotating component, a third rotating component, and a connecting component;

[0006] The first rotating member is slidably and rotatably connected to the first support member, and is also rotatably connected to the connecting member and the main body; one end of the second rotating member is rotatably connected to the main body and the other end is rotatably connected to the connecting member; one end of the third rotating member is rotatably connected to the main body and the other end is slidably connected to the connecting member; the connecting member is rotatably connected to the first support member.

[0007] The second rotating mechanism is movably connected to the second support member, and is movably connected to the second support member;

[0008] When the first support and the second support are folded or unfolded, the first rotating member of the first rotating mechanism slides and rotates relative to the main body, the first rotating member of the first rotating mechanism slides and rotates relative to the first support, and the second and third rotating members of the first rotating mechanism rotate relative to the main body.

[0009] Secondly, this application provides a folding housing, the folding housing comprising two housings and a folding device as described in the first aspect, the folding device being located between the two housings, the two housings being respectively connected to a connector of a first rotating mechanism and a connector of a second rotating mechanism of the folding device, the two housings rotating to switch between an unfolded state and a folded state when the connector of the first rotating mechanism rotates and the connector of the second rotating mechanism rotates.

[0010] Thirdly, this application provides an electronic device, which includes a foldable screen and a folding device as described in the first aspect, or the electronic device includes a foldable screen and a foldable housing as described in the second aspect; the screen is supported by a first support member and a second support member in the folding device, and when the electronic device is folded, the first support member and the second support member fold together; when the electronic device is unfolded, the first support member and the second support member unfold together, and the screen unfolds.

[0011] In summary, in the folding device provided by the embodiments of this application, the first rotating member of the first rotating mechanism is slidably and rotatably connected to the first supporting member, the first rotating member of the first rotating mechanism is also rotatably connected to the connecting member of the first rotating mechanism, and the first rotating member of the first rotating mechanism is also slidably and rotatably connected to the main body. Therefore, when the first supporting member moves relative to the main body, there are both displacement changes and angle changes between the first supporting member and the first rotating member of the first rotating mechanism. Thus, the first supporting member has a large degree of freedom during movement, which is beneficial to improving the bending stress of the screen supported by the first supporting member, thereby ensuring that the screen is not easily damaged.

[0012] Furthermore, in the folding device provided in this application embodiment, one end of the second rotating member of the first rotating mechanism is rotatably connected to the main body, and the other end is rotatably connected to the connecting member; one end of the third rotating member of the first rotating mechanism is rotatably connected to the main body, and the other end is slidably connected to the connecting member of the first rotating mechanism. Therefore, the second rotating member and the third rotating member of the first rotating mechanism are not directly connected to the first support member. Consequently, the first support member is less likely to be restricted in its degree of freedom of movement by the influence of the second and third rotating members of the first rotating mechanism. Instead, the first support member has a greater degree of freedom under the action of the first connecting member. Attached Figure Description

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] Furthermore, the following descriptions of various embodiments are based on the accompanying illustrations and are used to illustrate specific embodiments that can be implemented in this application. Directional terms used in this application, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying illustrations. Therefore, the directional terms used are for better and clearer explanation and understanding of this application, and are not intended to indicate or imply that the referred device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0063] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," and "set on" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0064] In the description of the embodiments of this invention, "connection" includes both direct and indirect connections. For example, a connection between A and B can be a direct connection or a connection via a third element C or more other elements. Connections also include integrated and non-integrated connections. An integrated connection means that A and B are formed and connected as a single unit, while a non-integrated connection means that A and B are not formed and connected as a single unit.

[0065] This application provides a folding device 100, a folding housing 10, and an electronic device 1. The electronic device 1 can be, but is not limited to, a foldable mobile phone, tablet computer, laptop computer, PDA, personal computer (PC), personal digital assistant (PDA), portable media player (PMP), navigation device, wearable device, smart bracelet, pedometer, etc. In the schematic diagram of this embodiment, a foldable mobile phone is used as an example for illustration; it should be understood that this should not be construed as a limitation on the electronic device 1 provided in this application embodiment.

[0066] Please refer to the following: Figure 1 , Figure 2 and Figure 3 , Figure 1 A schematic diagram of an electronic device provided in one embodiment of this application in a flattened state; Figure 2 for Figure 1 The diagram shows the electronic device in a folded state; Figure 3 for Figure 1The diagram shows an exploded perspective view of the electronic device. The electronic device 1 in this embodiment is a foldable electronic device 1, having a flattened state and a folded state, and can switch between the flattened state and the folded state. In this embodiment, the flattened state refers to a state where the two opposing parts of the electronic device 1 are flat or nearly flat. The folded state refers to a state where the two opposing parts of the electronic device 1 are bent and positioned opposite each other. The flattened and folded states of the electronic device 1 will be described later in conjunction with the flattened and folded states of the folding device 100.

[0067] The electronic device 1 includes a foldable housing 10 and a foldable screen 30 supported on the foldable housing 10. The foldable screen 30 can be, but is not limited to, various foldable components with corresponding functions such as a foldable display screen, a foldable touchscreen, or a foldable touch display screen, or a flexible component fixedly attached to a flexible support component, such as a foldable display screen, a foldable touchscreen, or a foldable touch display screen with a flexible steel plate attached. When the foldable housing 10 is in a folded state, the screen 30 is also in a folded state; when the foldable housing 10 is in a flattened state, the screen 30 is also in a flattened state. In one embodiment, the screen 30 can be folded or flattened along with the foldable housing 10. Specifically, the screen 30 can be folded along with the folding of the foldable housing 10, and can be flattened along with the flattening of the foldable housing 10. In another embodiment, the foldable housing 10 can be folded or flattened along with the screen 30. Specifically, the foldable housing 10 can be folded along with the folding of the screen 30, and can be flattened along with the flattening of the screen 30. This application does not limit whether the folding housing 10 drives the screen 30 to fold or flatten, nor does it limit whether the screen 30 drives the folding housing 10 to fold or flatten, as long as the screen 30 is also in a folded state when the folding housing 10 is in a folded state, and also in a flattened state when the folding housing 10 is in a flattened state.

[0068] The folding housing 10 includes two housings 500 (also called a mid-frame) and a folding device 100 connecting the two housings 500. The two housings 500 have a folded state and a flattened state. When the folding device 100 is in the folded state, both housings 500 are in the folded state; when the folding device 100 is in the flattened state, both housings 500 are also in the flattened state. The relationship between the housings 500 and the folding device 100 will be described in detail later with reference to the specific structure of the folding device 100. The screen 30 includes a bendable portion 310 and two non-bendable portions 320 connected to opposite sides of the bendable portion 310. One non-bendable portion 320 of the screen 30 is fixed to one of the two housings 500, and the other non-bendable portion 320 is fixed to the other of the two housings 500. The bendable portion 310 is disposed corresponding to the foldable device 100 and is disposed on one side of the folding device 100. One non-bending portion 320 of the screen 30 is fixed to one of the two housings 500 by means of, but not limited to, adhesive or double-sided tape. The other non-bending portion 320 of the screen 30 is fixed to the other of the two housings 500 by means of, but not limited to, adhesive or double-sided tape.

[0069] In this embodiment, the electronic device 1 is illustrated as an inward-folding electronic device 1, that is, when the electronic device 1 is in a folded state, the screen 30 is located inside the folding device 100. The inward-folding electronic device 1 can effectively reduce the possibility of the screen 30 being impacted, which is beneficial to extending the service life of the screen 30. It should be noted that the main inventive concept provided in this application can also be applied to outward-folding electronic devices 1.

[0070] When the electronic device 1 is in a flattened state, the screen 30 is also flattened and can be exposed, which is beneficial for realizing large-screen display or large-screen operation. When the electronic device 1 is in a folded state, the screen 30 is also folded, so the electronic device 1 is easy to carry. It is understood that the above description of the electronic device 1 is only an introduction to one application of the folding device 100 and the folding housing 10, and should not be construed as a limitation on the folding device 100 and the folding housing 10 provided in this application. The folding device 100 will be described below with reference to the accompanying drawings.

[0071] Please refer to the following: Figure 4 , Figure 5 and Figure 6 , Figure 4 A perspective view of a folding device provided in one embodiment of this application; Figure 5 for Figure 4 A three-dimensional schematic diagram of the folding device from another perspective; Figure 6 for Figure 4 An exploded view of the folding device 100. The folding device 100 includes a support assembly 1100 and a rotating assembly 1200. The support assembly 1100 includes two support members, which are named first support member 111 and second support member 111' for ease of naming. The rotating assembly 1200 includes a main body 120 and two rotating mechanisms connected to the main body 120. For ease of description, the two rotating mechanisms are named first rotating mechanism 130 and second rotating mechanism 130' for ease of description. Both the first rotating mechanism 130 and the second rotating mechanism 130' include a first rotating member 131, a second rotating member 132, a third rotating member 133, and a connecting member 134.

[0072] The first rotating mechanism 130 includes a first rotating member 131, a second rotating member 132, a third rotating member 133, and a connecting member 134. In the first rotating mechanism 130: the first rotating member 131 is slidably and rotatably connected to the first support member 111, and is also rotatably connected to the connecting member 134, and is also slidably and rotatably connected to the main body 120; one end of the second rotating member 132 is rotatably connected to the main body 120, and the other end is rotatably connected to the connecting member 134; one end of the third rotating member 133 is rotatably connected to the main body 120, and the other end is slidably connected to the connecting member 134; the connecting member 134 is rotatably connected to the first support member 111.

[0073] The second rotating mechanism 130' is movably connected to the main body 120 and the second support member 111'. When the first support member 111 and the second support member 111' are folded or unfolded, the first rotating member 131 of the first rotating mechanism 130 slides and rotates relative to the main body 120, the first rotating member 131 of the first rotating mechanism 130 slides and rotates relative to the first support member 111, and the second rotating member 131 and the third rotating member 132 of the first rotating mechanism 130 rotate relative to the main body 120.

[0074] In this embodiment, the second rotating mechanism 130' also includes a first rotating member 131, a second rotating member 132, and a third rotating member 133 as an example for illustration and explanation. It is understood that in other embodiments, the components included in the second rotating mechanism 130' may differ from those included in the first rotating mechanism 130. For example, the second rotating mechanism 130' may include one rotating member, two rotating members, or more than three rotating members; this is not limited in this embodiment. The requirement is that the second rotating mechanism 130' can be movably connected to the main body 120 and the second support member 111'.

[0075] In this embodiment, in the second rotating mechanism 130': the first rotating member 131 is slidably and rotatably connected to the second support member 111', the first rotating member 131 is also rotatably connected to the connecting member 134, and the first rotating member 131 is also slidably and rotatably connected to the main body 120; one end of the second rotating member 132 is rotatably connected to the main body 120, and the other end is rotatably connected to the connecting member 134; one end of the third rotating member 133 is rotatably connected to the main body 120, and the other end is slidably connected to the connecting member 134; the connecting member 134 is rotatably connected to the second support member 111'.

[0076] When the first support member 111 and the second support member 111' are folded or unfolded, the first rotating member 131 of the second rotating mechanism 130' slides and rotates relative to the main body 120, and slides and rotates relative to the second support member 111', while the second rotating member 132 and the third rotating member 133 of the second rotating mechanism 130' rotate relative to the main body 120.

[0077] When the folding device 100 is folded, the first rotating member 131 of the first rotating mechanism 130 and the second rotating mechanism 130' slides and rotates relative to the main body 120, the first rotating member 131 of the first rotating mechanism 130 slides and rotates relative to the first support member 111, the first rotating member 131 of the second rotating mechanism 130' slides and rotates relative to the second support member 111', the second rotating member 132 and the third rotating member 133 of the first rotating mechanism 130 and the second rotating mechanism 130' rotate, and the first support member 111 and the second support member 111' fold together. When the folding device 100 is unfolded, the first rotating member 131 of the first rotating mechanism 130 and the second rotating mechanism 130' slides and rotates relative to the main body 120, the first rotating member 131 of the first rotating mechanism 130 slides and rotates relative to the first support member 111, the first rotating member 131 of the second rotating mechanism 130' slides and rotates relative to the second support member 111', the second rotating member 132 and the third rotating member 133 of the first rotating mechanism 130 and the second rotating mechanism 130' rotate, and the first support member 111 and the second support member 111' unfold relative to each other.

[0078] The first support member 111, also called a ramp, is disposed corresponding to a bendable portion 310 of the screen 30. The second support member 111', also called a ramp, is disposed corresponding to another bendable portion 310 of the screen 30. In one embodiment, the first support member 111 is fixed to one end of the bendable portion 310 by adhesive or double-sided tape, and the second support member 111' is fixed to the other end of the bendable portion 310 by adhesive or double-sided tape. In another embodiment, the first support member 111 and the second support member 111' are not fixed to the bendable portion 310. When the first support member 111 and the second support member 111' bend towards each other, the first support member 111 and the second support member 111' limit the position of the bendable portion 310 to prevent the bendable portion 310 from shifting.

[0079] The first support member 111 and the second support member 111' are flattened when the folding device 100 is in a flattened state, and can support the screen 30 in a flattened state when applied to the electronic device 1. When the first support member 111 and the second support member 111' are folded when the folding device 100 is in a folded state, and the end of the first support member 111 near the main body 120 is inclined relative to the end away from the main body 120, and the end of the second support member 111' near the main body 120 is inclined relative to the end away from the main body 120, such that when the folding device 100 is in a folded state, the distance d1 between the ends of the first support member 111 and the second support member 111' near the main body 120 is greater than the distance d2 between the ends of the first support member 111 and the second support member 111' away from the main body 120 (see...). Figure 2 Therefore, when the folding device 100 is in the folded state, its cross-section presents a teardrop-shaped receiving space. When the folding device 100 is applied to the folding housing 10 and the electronic device 1, it helps to reduce the folding gap between the folding housing 10 and the electronic device 1, improves the appearance, and increases the bending control of the screen 30 in the electronic device 1, which helps to reduce the creases of the screen 30.

[0080] The first support member 111 and the second support member 111' can be bent or unfolded relative to each other. Therefore, the folding device 100 has a folded state and a flattened state, and can switch between the flattened state and the folded state. When the folding device 100 is in the folded state, the first support member 111 and the second support member 111' are both located on the same side of the main body 120, and the first support member 111 cannot be folded further. When the folding device 100 is in the flattened state, the first support member 111 and the second support member 111' are both located on opposite sides of the main body 120, and the first support member 111 and the second support member 111' are in a flat or nearly flat state. When the first support member 111 and the second support member 111' are in the flat state, the surfaces of the first support member 111 and the second support member 111' adjacent to the screen 30 are coplanar. When the first support member 111 and the second support member 111' are in a nearly flat state, the surfaces of the first support member 111 and the second support member 111' adjacent to the screen 30 are approximately coplanar. The state of the folding device 100 is related to the state of the electronic device 1. In one embodiment, when the first support member 111 and the second support member 111' in the folding device 100 bend relative to each other, the screen 30 will bend relative to each other; when the first support member 111 and the second support member 111' in the folding device 100 are flattened relative to each other, the screen 30 will be flattened relative to each other. In another embodiment, when the screen 30 is bent relative to each other, the first support member 111 and the second support member 111' will bend relative to each other; when the screen 30 is flattened relative to each other, the first support member 111 and the second support member 111' will be flattened relative to each other. Therefore, when the folding device 100 is in a folded state, the electronic device 1 is also in a folded state; when the folding device 100 is in a flattened state, the electronic device 1 is also in a flattened state. This application does not limit the timing or active / passive relationship of the relative movement of the first support member 111 and the second support member 111' and the relative bending of the screen 30. In other words, in this embodiment, when the electronic device 1 is folded, the two housings 500 fold together, the first support member 111 and the second support member 111' fold together, and the screen 30 folds together; when the electronic device 1 is unfolded, the two housings 500 unfold together, the first support member 111 and the second support member 111' unfold together, and the screen 50 unfolds.

[0081] The main body 120 is also called a support or bracket. A first support member 111 is connected to the main body 120 via a first rotating mechanism 130, and a second support member 111' is connected to the main body 120 via a second rotating mechanism 130'. When the folding device 100 is in a flattened state, the first support member 111 and the second support member 111' are respectively disposed on both sides of the main body 120. The first rotating mechanism 130 and the second rotating mechanism 130' are symmetrically or asymmetrically arranged about the main body 120. When the first rotating mechanism 130 and the second rotating mechanism 130' are symmetrically arranged about the main body 120, they can be symmetrically arranged on both sides of the main body 120 along the rotation axis of the folding device 100. In this embodiment and its schematic diagram, the first rotating mechanism 130 and the second rotating mechanism 130' are symmetrically arranged on both sides of the main body 120 along the rotation axis of the folding device 100, which should not be construed as a limitation on the folding device 100 provided in this application.

[0082] The folding device 100 is located between the two housings 500. The two housings 500 are respectively connected to the connector 134 of the first rotating mechanism 130 and the connector 134 of the second rotating mechanism 130' of the folding device 100. When the connector 134 of the first rotating mechanism 130 and the connector 134 of the second rotating mechanism 130' rotate, the two housings 500 rotate to switch between an unfolded state and a folded state. It should be noted that this application does not limit the active and passive relationship, or the timing, between the rotation of the two housings 500 and the rotation of the connector 134 of the first rotating mechanism 130 and the connector 134 of the second rotating mechanism 130'.

[0083] The connector 134 and the housing 500 can be an integral structure or a separate structure. When the connector 134 and the housing 500 are an integral structure, they can be manufactured in one process; however, for ease of understanding, the connector 134 and the housing 500 are given different names. When the connector 134 and the housing 500 are separate structures, they are two independent parts, and the connector 134 is fixed to the housing 500 by various methods such as bonding, screw connection, and snap-fit ​​connection. This embodiment is only used to illustrate the separate structure of the connector 134 and the housing 500. It can be understood that the connection method between the connector 134 in the first rotating mechanism 130 and one housing 500 can be the same as or different from the connection method between the connector 134 in the second rotating mechanism 130' and another housing 500.

[0084] The connection relationship between the first rotating component 131, the second rotating component 132, the third rotating component 133 and the connecting component 134 in the first rotating mechanism 130 and the main body 120 and the first support component 111 is described below.

[0085] The first rotating member 131 of the first rotating mechanism 130 is slidably and rotatably connected to the first support member 111, and is also rotatably connected to the connecting member 134. The first rotating member 131 is also slidably and rotatably connected to the main body 120. Correspondingly, the first rotating member 131 of the second rotating mechanism 130' is slidably and rotatably connected to the second support member 111', and is also rotatably connected to the connecting member 134. The first rotating member 131 is also slidably and rotatably connected to the main body 120. Therefore, when the folding device 100 is in the flattened state, the first support member 111 and the second support member 111' can provide better support for the screen 30; when the folding device 100 is in the folded state, the cross-section of the folding device 100 presents a teardrop-shaped receiving space. When the folding device 100 is applied to the folding housing 10 and the electronic device 1, it helps to reduce the folding gap of the folding housing 10 and the electronic device 1, improve the appearance, and increase the bending control of the screen 30 in the electronic device 1, which helps to reduce the creases of the screen 30.

[0086] It should be noted that rotation refers to the ability of two moving parts to move in a circle around a rotation axis. When two moving parts rotate, they can move a portion or all of the circle around the rotation axis. For example, the second rotating part 132 of the first rotating mechanism 130 is rotatably connected to the main body 120, meaning that the second rotating part 132 of the first rotating mechanism 130 and the main body 120 can move in a circle around the rotation axis. Sliding refers to the parallel movement of two moving parts, with only displacement changes and no angular changes between them. For example, the other end of the third rotating part 133 is slidably connected to the connecting part 134, meaning that only displacement changes and no angular changes occur between the other end of the third rotating part 133 and the connecting part 134. Rolling refers to both displacement changes and angular changes between two moving parts. For example, in this embodiment, the first rotating part 131 of the first rotating mechanism 130 is slidably and rotatably connected to the first support part 111, meaning that the first rotating part 131 of the first rotating mechanism 130 is rolledly connected to the first support part 111. In other words, there is both displacement and angle change between the first rotating member 131 and the first support member 111 of the first rotating mechanism 130.

[0087] In summary, in the folding device 100 provided in this application embodiment, the first rotating member 131 of the first rotating mechanism 130 is slidably and rotatably connected to the first support member 111, the first rotating member 131 of the first rotating mechanism 130 is also rotatably connected to the connecting member 134 of the first rotating mechanism 130, and the first rotating member 131 of the first rotating mechanism 130 is also slidably and rotatably connected to the main body 120. Therefore, when the first support member 111 moves relative to the main body 120, there are both displacement changes and angle changes between the first support member 111 and the first rotating member 131 of the first rotating mechanism 130. Thus, the first support member 111 has a large degree of freedom during movement, which is beneficial to improving the bending stress of the screen supported by the first support member 111, thereby ensuring that the screen is not easily damaged.

[0088] Furthermore, in the folding device 100 provided in this application embodiment, one end of the second rotating member 132 of the first rotating mechanism 130 is rotatably connected to the main body 120, and the other end is rotatably connected to the connecting member 134; one end of the third rotating member 133 of the first rotating mechanism 130 is rotatably connected to the main body 120, and the other end is slidably connected to the connecting member 134 of the first rotating mechanism 130. Therefore, the second rotating member 132 of the first rotating mechanism 130 is not directly connected to the first support member 111. Consequently, the first support member 111 is not easily restricted in its movement by the second rotating member 132 and the third rotating member 133 of the first rotating mechanism 130. Instead, the first support member 111 has a greater degree of freedom under the action of the first connecting member 134.

[0089] Accordingly, in the folding device 100 provided in this application embodiment, the first rotating member 131 of the second rotating mechanism 130' is slidably and rotatably connected to the second support member 111', the first rotating member 131 of the second rotating mechanism 130' is also rotatably connected to the connecting member 134 of the second rotating mechanism 130', and the first rotating member 131 of the second rotating mechanism 130' is also slidably and rotatably connected to the main body 120. Therefore, when the second support member 111' moves relative to the main body 120, there are both displacement changes and angle changes between the second support member 111' and the first rotating member 131 of the second rotating mechanism 130'. Therefore, the second support member 111' has a large degree of freedom during movement, which is beneficial to improving the bending stress of the second support member 111' on the screen it supports, thereby ensuring that the screen is not easily damaged.

[0090] Furthermore, in the folding device 100 provided in this application embodiment, one end of the second rotating member 132 of the second rotating mechanism 130' is rotatably connected to the main body 120, and the other end is rotatably connected to the connecting member 134; one end of the third rotating member 133 of the second rotating mechanism 130' is rotatably connected to the main body 120, and the other end is slidably connected to the connecting member 134 of the second rotating mechanism 130'. Therefore, the second rotating member 132 of the second rotating mechanism 130' is not directly connected to the second support member 111'. Consequently, the second support member 111' is less likely to be restricted in its movement by the second rotating member 132 and the third rotating member 133 of the second rotating mechanism 130'. Instead, the second support member 111' has a greater degree of freedom under the action of the first connecting member 134.

Please refer to the attached diagram as well. Figures 14 to 17 , Figure 14 This is a partial cross-sectional view of the folding device shown in Figure 7 when it is in the folded state. Figure 15 for Figure 14 A schematic diagram of the first rotating component, main body, first support component, and connecting component of the first rotating mechanism in the folding device in the folded state provided in the diagram; Figure 16 for Figure 15 An exploded three-dimensional view of the structure shown; Figure 17 for Figure 15 Cross-sectional view along line III-III; Figure 18 for Figure 2A partial structural schematic diagram along the GG section line. The first rotating component 131 of the first rotating mechanism 130 is connected to the first support component 111 via a connecting shaft and an arc-shaped sliding groove. For ease of description, the connecting shaft is named the first connecting shaft 1314, and the arc-shaped sliding groove is named the first arc-shaped sliding groove 1113. In other words, the first rotating component 131 of the first rotating mechanism 130 is connected to the first support component 111 via the first connecting shaft 1314 and the first arc-shaped sliding groove 1113.

[0093] The first rotating member 131 of the first rotating mechanism 130 is connected to the first support member 111 via a first connecting shaft 1314 and a first arc-shaped sliding groove 1113, so that the first rotating member 131 can slide and rotate on the first support member 111. The first arc-shaped sliding groove 1113 can be provided on one of the first rotating member 131 and the first support member 111 of the first rotating mechanism 130, and the first connecting shaft 1314 can be fixed to the other of the first rotating member 131 and the first support member 111. The first rotating member 131 of the first rotating mechanism 130 is connected to the first support member 111 through the first connecting shaft 1314 and the first arc-shaped sliding groove 1113. This allows the first support member 111 to move relative to the main body 120, resulting in both displacement and angular changes between the first support member 111 and the first rotating member 131 of the first rotating mechanism 130. Therefore, the first support member 111 has a large degree of freedom during movement, which helps to reduce the bending stress on the screen supported by the first support member 111, thereby ensuring that the screen is not easily damaged.

[0094] In this embodiment, the first arc-shaped groove 1113 is disposed on the first support member 111, and the first connecting shaft 1314 is fixed to the first rotating member 131, with one end of the first connecting shaft 1314 located within the first arc-shaped groove 1113. Compared to the first arc-shaped groove 1113 being disposed on the first connecting member 134 and the first connecting member 134 being fixed to the first support member 111, in this embodiment, the first arc-shaped groove 1113 is disposed on the first support member 111, and the first connecting shaft 1314 is fixed to the first rotating member 131. This facilitates the miniaturization of the first rotating member 131, thereby contributing to the miniaturization of the folding device 100.

[0095] Furthermore, in this embodiment, the first rotating member 131 of the first rotating mechanism 130 has a connecting hole. For ease of description, the connecting hole of the first rotating member 131 of the first rotating mechanism 130 is named connecting hole 1311 (see...). Figure 10The first support member 111 has a first support body portion 1111 and a first connecting portion 1112 connected together. The first connecting portion 1112 has a first arc-shaped groove 1113. One end of the first connecting shaft 1314 is located in the connecting hole 1311 and fixed to the first rotating member 131, and the other end of the first connecting shaft 1314 is located in the first arc-shaped groove 1113. In other embodiments, the first rotating member 131 may not have the connecting hole 1311, and the first connecting shaft 1314 may be a separate structure from the first connecting member 134 and fixed to the first connecting member 134, or the first connecting shaft 1314 and the first connecting member 134 may be an integral structure.

[0096] The connecting hole 1311 can be a through hole or a blind hole, as long as one end of the first connecting shaft 1314 is located inside the connecting hole 1311 and fixed to the first rotating member 131. In the schematic diagram of this embodiment, the connecting hole 1311 is illustrated as a through hole. When the connecting hole 1311 is a through hole, it is convenient for the first connecting shaft 1314 to be installed inside the connecting hole 1311. The other end of the first connecting shaft 1314 is located inside the first arc-shaped slide groove 1113 and can move within the first arc-shaped slide groove 1113. When the first support member 111 moves relative to the main body 120, the first end of the first connecting shaft 1314 can slide and rotate within the first arc-shaped slide groove 1113.

[0097] The first arc-shaped groove 1113 of the first connecting portion 1112 has a first limiting end 1114 and a second limiting end 1115 located at opposite ends. The first limiting end 1114 is further away from the main body 120 than the second limiting end 1115. When the folding device 100 is in a flattened state, the other end of the first connecting shaft 1314 is located at the first limiting end 1114 (see...). Figure 11 When the folding device 100 is in the folded state, the other end of the first connecting shaft 1314 is located at the second limiting end 1115 (see...). Figure 17 ).

[0098] The first limiting end 1114 and the second limiting end 1115 are the two ends of the first arc-shaped slide groove 1113. The first limiting end 1114 is further away from the main body 120 than the second limiting end 1115; in other words, the first limiting end 1114 is farther from the main body 120, and the second limiting end 1115 is closer to the main body 120. When the folding device 100 is in a flattened state, the other end of the first connecting shaft 1314 is located at the first limiting end 1114, which can prevent the first support member 111 from continuing to unfold and damaging the screen. When the folding device 100 is in a folded state, the other end of the first connecting shaft 1314 is located at the second limiting end 1115, which can prevent the first support member 111 from folding further and damaging the screen.

[0099] In one embodiment, when the folding device 100 is in a flattened state, and when one end of the first connecting shaft 1314 is located at the first limiting end 1114, the one end of the first connecting shaft 1314 can abut against the first limiting end 1114. In another embodiment, when the folding device 100 is in a flattened state, and when the other end of the first connecting shaft 1314 is located at the first limiting end 1114, there is a gap between one end of the first connecting shaft 1314 and the first limiting end 1114 to prevent the folding device 100 from failing to flatten properly due to structural tolerances or other reasons.

[0100] In one embodiment, when the folding device 100 is in a folded state, and when one end of the first connecting shaft 1314 is located at the second limiting end 1115, the one end of the first connecting shaft 1314 can abut against the second limiting end 1115. In another embodiment, when the folding device 100 is in a flattened state, and when one end of the first connecting shaft 1314 is located at the second limiting end 1115, there is a gap between the one end of the first connecting shaft 1314 and the second limiting end 1115 to prevent the folding device 100 from failing to fold properly due to structural tolerances or other reasons.

[0101] Please refer to further information. Figure 19 , Figure 19 This is a schematic diagram showing the first to fourth distances in the folding device. The first support body 1111 has a first support surface 111a that faces away from the first connecting part 1112. When the folding device 100 is in a flattened state, the distance between the first connecting shaft 1314 and the first support surface 111a is the first distance d. 01When the folding device 100 is in the folded state, the distance between the first connecting shaft 1314 and the first support surface 111a is the second distance d. 02 Wherein, the first distance d 01 Greater than the second distance d 02 .

[0102] When the folding device 100 is in the flattened state, the first connecting shaft 1314 is located at the first limiting end 1114; when the folding device 100 is in the folded state, the first connecting shaft 1314 is located at the second limiting end 1115. Therefore, the distance between the first limiting end 1114 and the first support surface 111a (i.e., the first distance d) is... 01 The distance d is greater than the distance between the second limiting end 1115 and the first support surface 111a (i.e., the second distance d). 02 When the folding device 100 is in a flattened state, and viewed from an upward angle with the first support surface 111a facing upwards, the first limiting end 1114 is lower than the second limiting end 1115. In this embodiment, the first distance is greater than the second distance to ensure that when the folding device 100 starts moving from the flattened state, the first support member 111 rotates counterclockwise, thereby enabling the first support member 111 to fold, thus allowing the folding device 100 to enter the folded state.

[0103] Please see Figure 8 , Figures 11 to 14 and Figure 17 The first arc-shaped groove 1113 also has a connecting arc segment 1116, which is connected between the first limiting end 1114 and the second limiting end 1115, and the connecting arc segment 1116 protrudes in a direction close to the first support surface 111a.

[0104] The connecting arc segment 1116 is located between the first limiting end 1114 and the second limiting end 1115, and connects the first limiting end 1114 and the second limiting end 1115. The connecting arc segment 1116 protrudes towards the first support surface 111a. Therefore, when the folding device 100 switches from the unfolded state to the folded state or from the folded state to the unfolded state, the movement speed of the first support member 111 relative to the first connecting member 134 of the first rotating mechanism 130 is relatively slow. If the movement speed of the first support member 111 relative to the first connecting member 134 of the first rotating mechanism 130 is relatively fast, then the lowest part of the screen 30 supported by the folding device 100 in the bent state ( Figure 2The position shown (corresponding to the part at the axis of the folding device 100) is such that, compared to the original position of the screen 30 in the flattened state, the part moves more in the direction away from the first support surface 111a. This makes the screen 30 more prone to interference with the decorative piece located on the side of the screen 30 away from the first support 111, and the screen 30 is easily damaged. In the folding device 100 provided in this embodiment, the connecting arc segment 1116 protrudes towards the first support surface 111a, thereby preventing damage to the screen 30 supported by the folding device 100 due to excessively rapid movement of the first support 111.

[0105] Please see Figures 8 to 11 The first rotating component 131 of the first rotating mechanism 130 is connected to the main body 120 through the second connecting shaft 1315 and the second arc-shaped slide groove 121.

[0106] In this embodiment, the first rotating member 131 of the first rotating mechanism 130 is connected to the main body 120 via a second connecting shaft 1315 and a second arc-shaped sliding groove 121, allowing the first rotating member 131 to slide and rotate on the main body 120. The second connecting shaft 1315 is disposed on one of the first rotating member 131 of the first rotating mechanism 130 and the main body 120, and the second arc-shaped sliding groove 121 is disposed on the other. The second connecting shaft 1315 and the second arc-shaped sliding groove 121 are connected to each other, allowing the first rotating member 131 to slide and rotate on the main body 120. The first rotating component 131 of the first rotating mechanism 130 is connected to the main body 120 via a second connecting shaft 1315 and a second arc-shaped sliding groove 121. This allows the first rotating component 131 of the first rotating mechanism 130 to undergo both displacement and angular changes relative to the main body 120 during movement, resulting in a large degree of freedom for the first rotating component 131. Because the first rotating component 131 is slidably and rotatably connected to the first support component 111, this large degree of freedom further increases the degree of freedom of the first support component 111. This further helps to reduce the bending stress on the screen supported by the first support component 111, thus ensuring that the screen is not easily damaged.

[0107] In this embodiment, the first rotating member 131 of the first rotating mechanism 130 has a second connecting shaft 1315, and the main body 120 has a second arc-shaped groove 121. In another embodiment, the first rotating member 131 has a second arc-shaped groove 121, and the main body 120 has a second rotating shaft. It is acceptable as long as the first rotating member 131 of the first rotating mechanism 130 and the main body 120 can be slidably and rotatably connected. In this embodiment, because the thickness of the main body 120 is relatively large, the second arc-shaped groove 121 is provided on the main body 120, and the second connecting shaft 1315 is fixed to the first rotating member 131 of the first rotating mechanism 130. This allows the thickness of the first rotating member 131 to be smaller, thus facilitating the miniaturization of the first rotating member 131 and the thinning of the folding device 100 when it is in the unfolded state.

[0108] Please see Figure 16 In this embodiment, the main body 120 has a first receiving space 120a. At least one of the two opposing sidewalls of the main body 120 is provided with a second arc-shaped groove 121. The second connecting shaft 1315 is disposed in the connecting hole 1312 of the first rotating member 131 and cooperates with the second arc-shaped groove 121. In this embodiment, the first rotating member 131 of the first rotating mechanism 130 has a connecting hole 1312. The second rotating shaft 1315 is partially disposed within the connecting hole 1312 and fixed to the first rotating member 131. In other embodiments, the second rotating shaft 1315 may not have the connecting hole 1312. The second rotating shaft 1315 may be a separate structure from the first rotating member 131 and fixed to the first rotating member 131, or the second rotating shaft 1315 and the first rotating member 131 may be an integral structure.

[0109] Specifically, the end faces adjacent to the first support member 111 and the second support member 111' when they are in a folded state are named the first end face 123, and the surface opposite to the first end face 123 is named the second end face 124. Furthermore, the main body 120 also has two connecting surfaces 125, which respectively connect the first end face 123 and the second end face 124. In other words, the main body 120 has a first end face 123, a second end face 124, and two connecting surfaces 125. The first end face 123 and the second end face 124 are arranged opposite to each other, and the connecting surfaces 125 connect the first end face 123 and the second end face 124, with the two connecting surfaces 125 also arranged opposite to each other. When the first support member 111 and the second support member 111' are in a folded state, one of the first support member 111 and the second support member 111' is located on one side of a connecting surface 125, and the other of the first support member 111 and the second support member 111' is located on one side of another connecting surface 125; when the first support member 111 and the second support member 111' are in a folded state, the first support member 111 and the second support member 111' are located on one side of the first end face 123, and the first end face 123 is adjacent to the first support member 111 and the second support member 111' relative to the second end face 124.

[0110] In this embodiment, the width of the first end face 123 is greater than the width of the second end face 124. Since the first end face 123 needs to have openings to install the first rotating member 131, the second rotating member 132, and the third rotating member 133, as well as components such as the screen 30, the larger width of the first end face 123 facilitates the installation of these components. The smaller size of the second end face 124 reduces the size of the main body 120. Furthermore, the connecting surface 125 is arc-shaped or approximately arc-shaped, which allows it to avoid interference between the first rotating member 131, the second rotating member 132, the third rotating member 133, and the housing 500 and other structural components when the folding device 100 is folded, preventing interference between these structural components and the connecting surface 125 during the folding process.

[0111] The opening of the first receiving space 120a is located on the first end face 123 and extends through one of the connecting surfaces 125. Since the support assembly 1100 includes the first support member 111 and the second support member 111', the main body 120 has two spaced-apart first receiving spaces 120a. In the schematic diagram of this embodiment, the two first receiving spaces 120a are arranged along the broadband direction of the main body 120 as an example.

[0112] The opening of the first receiving space 120a is located on the first end face 123 and extends through one of the connecting surfaces 125 therethrough, thereby facilitating the installation of the first rotating member 131 in the first receiving space 120a and facilitating the connection between the first rotating member 131 and the main body 120.

[0113] The connecting hole 1312 can be a through hole or a blind hole, as long as the second connecting shaft 1315 is partially located within the connecting hole 1311 and fixed to the first rotating member 131. In the schematic diagram of this embodiment, a through hole 1312 is used as an example. When the connecting hole 1312 is a through hole, it facilitates the installation of the second connecting shaft 1315 within it. The second connecting shaft 1315 is partially located within the second arc-shaped slide groove 121 and can move within it. When the first support member 111 moves relative to the main body 120, the second connecting shaft 1315 can slide and rotate within the second arc-shaped slide groove 121.

[0114] At least one of the two opposing sidewalls of the main body 120 forming the first receiving space 120a is provided with a second arc-shaped groove 121, including one sidewall of the main body 120 forming the first receiving space 120a having the second arc-shaped groove 121; or, both sidewalls of the main body 120 forming the receiving space having the second arc-shaped groove 121. When both sidewalls of the main body 120 forming the receiving space have the second arc-shaped groove 121, the second rotating shaft can slide and rotate more stably within the second arc-shaped groove 121.

[0115] Please refer to further information. Figure 18 The first rotating component 131 of the first rotating mechanism 130 and the connecting component 134 of the first rotating mechanism 130 are connected by a third connecting shaft 1316 and a first connecting hole 1313.

[0116] In one embodiment, the third connecting shaft 1316 is disposed on one of the first rotating member 131 and the connecting member 134 of the first rotating mechanism 130, and the first connecting hole 1313 is disposed on the other of the first rotating member 131 and the connecting member 134 of the first rotating mechanism 130. Specifically, the third connecting shaft 1316 is disposed on the first rotating member 131 of the first rotating mechanism 130, and the first connecting hole 1313 is disposed on the connecting member 134 of the first rotating mechanism 130. Alternatively, the third connecting shaft 1316 is disposed on the connecting member 134 of the first rotating mechanism 130, and the first connecting hole 1313 is disposed on the first rotating member 131 of the first rotating mechanism 130. In another embodiment, both the first rotating member 131 and the connecting member 134 of the first rotating mechanism 130 are provided with first connecting holes 1313. The third connecting shaft 1316 passes through the first connecting holes 1313 of the first connecting member 134 of the first rotating mechanism 130 and the first connecting holes 1313 of the connecting member 134 of the first rotating mechanism 130. As long as the first rotating member 131 and the connecting member 134 of the first rotating mechanism 130 are connected by the third connecting shaft 1316 and the first connecting hole 1313, a rotational engagement between the first rotating member 131 and the connecting member 134 of the first rotating mechanism 130 is achieved.

[0117] The first rotating component 131 of the first rotating mechanism 130 and the connecting component 134 of the first rotating mechanism 130 are connected by a third connecting shaft 1316 and a first connecting hole 1313. That is, the solid connecting shaft allows for a rotatable connection between the first rotating component 131 and the connecting component 134 of the first rotating mechanism 130. The solid connecting shaft reduces the space required for the rotatable connection between the first rotating component 131 and the connecting component 134 of the first rotating mechanism 130, which is beneficial for miniaturizing the mating components. Furthermore, the clearance between the third connecting shaft 1316 and the first connecting hole 1313 is relatively easy to control, reducing the likelihood of wobbling.

[0118] Please refer to the following: Figures 20 to 28 , Figure 20 for Figure 4 A schematic cross-sectional view of the folding device shown along line IV-IV; Figure 21 for Figure 20 A schematic diagram of the folding device shown from another perspective; Figure 22 for Figure 4 A schematic diagram showing the cooperation relationship between the second rotating component of the first rotating mechanism and the main body and connecting components in the folding device shown; Figure 23 for Figure 22 An exploded three-dimensional view of the structure shown; Figure 24 for Figure 22 A cross-sectional view along the VV line; Figure 25 for Figure 20 A cross-sectional view of the folding device in a folded state; Figure 26 for Figure 25 A schematic diagram showing the cooperation relationship between the second rotating component of the first rotating mechanism, the main body, and the connecting component in the folding device in a folded state. Figure 27 for Figure 26 An exploded three-dimensional view of the structure shown; Figure 28 for Figure 26 A cross-sectional view along line VI-VI. The main body 120 also has a second receiving space 120b, one end of the second rotating member 132 of the first rotating mechanism 130 is disposed in the second receiving space 120b, and is connected to the main body 120 through a first arc groove 1321 and a first arc rail 122.

[0119] The second rotating member 132 is connected to the main body 120 through a first arc groove 1321 and a first arc rail 122. The first arc groove 1321 is provided on one of the second rotating member 132 and the main body 120, and the first arc rail 122 is provided on the other of the second rotating member 132 and the main body 120.

[0120] Please continue reading. Figure 23 In the schematic diagram of the embodiment, the two sidewalls are arranged along the length of the main body 120. The main body 120 defines two opposite sidewalls of the second receiving space 120b, each provided with one of the first arc groove 1321 and the first arc rail 122. The second rotating member 132 of the first rotating mechanism 130 has the other of the first arc groove 1321 and the first arc rail 122 on its opposite sides. Therefore, when the second rotating member 132 of the first rotating mechanism 130 engages with the main body 120, the stability of the second rotating member 132 of the first rotating mechanism 130 relative to the main body 120 is improved through the engagement of the two first arc grooves 1321 and the two first arc rails 122.

[0121] In the schematic diagram of this embodiment, the example shown is that the main body 120 has two opposing sidewalls forming the second receiving space 120b with first arc tracks 122, and the second rotating member 132 has two opposing sides with first arc grooves 1321. This should not be construed as a limitation on the folding device 100 provided in this application embodiment. In other embodiments, the main body 120 has two opposing sidewalls forming the second receiving space 120b with first arc grooves 1321, and the second rotating member 132 has two opposing sides with first arc tracks 122. In another embodiment, one of the two opposing sidewalls of the main body 120 forming the second receiving space 120b is provided with a first arc track 122, and the other sidewall is provided with a first arc groove 1321. Correspondingly, the two opposite sides of the second rotating member 132 are respectively provided with a first arc groove 1321 and a first arc track 122. The first arc groove 1321 of the second rotating member 132 cooperates with the first arc track 122 of the main body 120, and the first arc track 122 of the second rotating member 132 cooperates with the first arc groove 1321 of the main body 120. In another embodiment, the main body 120 and the second rotating member 132 of the first rotating mechanism 130 are connected by a pair of first arc tracks 122 and first arc grooves 1321. The first arc track 122 is provided on one of the main body 120 and the second rotating member 132 of the first rotating mechanism 130, and the first arc groove 1321 is provided on the other of the main body 120 and the second rotating member 132 of the first rotating mechanism 130.

[0122] The opening of the second receiving space 120b is located on the first end face 123 and extends through one of the connecting surfaces 125. Since the support assembly 1100 includes a first support member 111 and a second support member 111', the main body 120 has two spaced-apart second receiving spaces 120b. In the schematic diagram of this embodiment, the two second receiving spaces 120b are arranged along the broadband direction of the main body 120 as an example.

[0123] The opening of the second receiving space 120b is located on the first end face 123 and extends through one of the connecting surfaces 125 therethrough, thereby facilitating the installation of the second rotating member 132 in the second receiving space 120b and facilitating the connection between the second rotating member 132 and the main body 120.

[0124] In this embodiment, the second rotating member 132 and the main body 120 are connected by a first arc groove 1321 and a first arc rail 122. On the one hand, this allows the second rotating member 132 to be rotatably connected to the main body 120. On the other hand, it facilitates the machining of the first arc groove 1321 and the first arc rail 122 on the second rotating member 132 and the main body 120. In addition, it also facilitates the assembly between the second rotating member 132 and the main body 120.

[0125] Furthermore, the rotation axis of the first arc groove 1321 and the first arc rail 122 when they rotate relative to each other is a virtual axis. In other words, the first arc groove 1321 and the first arc rail 122 rotate around the virtual axis when they rotate relative to each other. Compared with a physical axis, the position of the virtual axis can be designed as needed. The rotation axis of the second rotating member 132 is closer to the theoretically designed position than the rotation axis of the main body 120, thus giving the second rotating member 132 a more precise motion trajectory when rotating relative to the main body 120. In addition, during the movement of the folding device 100 or when the folding device 100 is in a flattened or folded state, it will not interfere with the screen 30 carried by the folding device 100. Moreover, when the rotation axis of the second rotating member 132 and the main body 120 is close to the screen 30, it will prevent the second rotating member 132 from damaging or puncturing the screen 30.

[0126] Please continue reading. Figures 20 to 28 The second rotating member 132 and the connecting member 134 are connected by a fourth connecting shaft 1322 and a second connecting hole 1323. The fourth connecting shaft 1322 is disposed in one of the second rotating member 132 and the connecting member 134, and the second connecting hole 1323 is disposed in the other of the second rotating member 132 and the connecting member 134.

[0127] In the schematic diagram of this embodiment, the second rotating member 132 and the connecting member 134 have second connecting holes 1323, the connecting member 134 has two second connecting holes 1323, and the fourth connecting shaft 1322 passes through three of the second connecting holes 1323. In other embodiments, the second rotating member 132 has a fourth connecting shaft 1322, and the connecting member 134 has second connecting holes 1323. Alternatively, in other embodiments, the second rotating member 132 has second connecting holes 1323, and the connecting member 134 has a fourth connecting shaft 1322.

[0128] Specifically, the connector 134 has a receiving space 134c. The receiving space 134c is used to receive the other end of the second rotating member 132. The two opposite sidewalls of the connector 134 forming the receiving space 134c each have a second connecting hole 1323. The other end of the second rotating member 132 also has a second connecting hole 1323. The fourth connecting shaft 1322 passes through the second connecting hole 1323 of the second rotating member 132 and the second connecting holes 1323 of the two opposite sidewalls of the receiving space 134c.

[0129] The fourth connecting shaft 1322 can also be a pin, and correspondingly, the second connecting hole 1323 is a pin hole.

[0130] In this embodiment, the second rotating member 132 and the connecting member 134 are connected by a fourth connecting shaft 1322 and a second connecting hole 1323. That is, the solid connecting shaft allows the second rotating member 132 and the connecting member 134 to be connected. The solid connecting shaft reduces the space required for the rotational connection between the second rotating member 132 and the connecting member 134, which is beneficial for miniaturizing the mating components. Furthermore, the clearance between the fourth connecting shaft 1322 and the second connecting hole 1323 is easier to control, reducing the likelihood of wobbling.

[0131] Please refer to the following: Figures 29 to 37 , Figure 29 for Figure 4 A schematic cross-sectional view of the folding device shown along line VII-VII; Figure 30 for Figure 29 A schematic diagram of the folding device from another perspective; Figure 31 for Figure 4 A schematic diagram showing the cooperation relationship between the third rotating component of the first rotating mechanism in the folding device and the main body and connecting components; Figure 32 for Figure 31 An exploded three-dimensional view of the structure shown; Figure 33 for Figure 31 A schematic cross-sectional view along line VIII-VIII; Figure 34 for Figure 29 A cross-sectional schematic diagram of the folding device implemented in the middle in a folded state; Figure 35 for Figure 34 A schematic diagram showing the cooperation relationship between the third rotating component and the main body and connecting components in the first rotating mechanism of the folding device in the folded state; Figure 36 for Figure 35 An exploded three-dimensional view of the structure shown; Figure 37 for Figure 35A cross-sectional view along line VIV-VIV. The third rotating member 133 of the first rotating mechanism 130 and the main body 120 are connected by a fifth connecting shaft 1361 and a third connecting hole 1331. In this embodiment, the third rotating member 133 of the first rotating mechanism 130 has the third connecting hole 1331, and the fifth connecting shaft 1361 is disposed in the main body 120 and passes through the third connecting hole 1331. In other embodiments, the connecting member 134 of the first rotating mechanism 130 has the fifth connecting shaft 1361, the third rotating member 133 of the first rotating mechanism 130 has the third connecting hole 1331, and the main body 120 has the third connecting hole 1331, with the fifth connecting shaft 1361 sleeved within the third connecting hole 1331.

[0132] Specifically, the third rotating member 133 of the first rotating mechanism 130 has a rotating part 1333, a connecting part 1334, and a limiting part 1332 connected in sequence. The rotating part 1333 and the main body 120 are connected by the fifth connecting shaft 1361 and the third connecting hole 1331. In this embodiment, the rotating part 1333 has the third connecting hole 1331, and the fifth connecting shaft 1361 passes through the third connecting hole 1331 and is fixed to the main body 120. In other embodiments, the rotating part 1333 has the fifth connecting shaft 1361, the main body 120 has the third connecting hole 1331, and the fifth connecting shaft 1361 is sleeved in the third connecting hole 1331.

[0133] Please see Figure 30 The connecting portion 1334 has a clearance space 133a to prevent interference between the third rotating member 133 of the first rotating mechanism 130 and the second decorative portion 142 of the decorative member 1400 when the third rotating member 133 of the first rotating mechanism 130 rotates relative to the main body 120. It should be noted that in other embodiments, the connecting portion 1334 does not have the clearance space 133a; correspondingly, the decorative member 1400 has a clearance notch to prevent interference between the third rotating member 133 of the first rotating mechanism 130 and the decorative member 1400 when the third rotating member 133 of the first rotating mechanism 130 rotates relative to the main body 120.

[0134] The main body 120 and the connecting member 134 of the first rotating mechanism 130 are connected via a fifth connecting shaft 1361 and a third connecting hole 1331. This solid connecting shaft allows for rotatable connection between the main body 120 and the connecting member 134 of the first rotating mechanism 130. The solid connecting shaft also reduces the space required for rotatable connection between the third rotating member 133 of the first rotating mechanism 130 and the connecting member 134, thus facilitating miniaturization of the mating components. Furthermore, the clearance between the fifth connecting shaft 1361 and the third connecting hole 1331 is relatively easy to control, reducing the likelihood of wobbling.

[0135] Please continue reading. Figure 4 and Figure 6 ,as well as Figures 30 to 33 The third rotating member 133 of the first rotating mechanism 130 is disposed on one side of the main body 120, and the folding device 100 further includes a limiting member 1300. The limiting member 1300 is disposed on the side of the main body 120 opposite to the third rotating member 133 of the first rotating mechanism 130, so as to limit the third rotating member 133 of the first rotating mechanism 130 in the direction of the main body 120 pointing towards the third rotating member 133 of the first rotating mechanism 130.

[0136] The folding device 100 also includes a limiting member 1300, which on the one hand prevents the third rotating member 133 of the first rotating mechanism 130 from falling off the main body 120; on the other hand, the limiting member 1300 is disposed on the side of the main body 120 away from the third rotating member 133 of the first rotating mechanism 130, which also facilitates the assembly of the limiting member 1300, the third rotating member 133 of the first rotating mechanism 130 and the main body 120.

[0137] The limiting member 1300 is disposed on the side of the main body 120 away from the third rotating member 133 of the first rotating mechanism 130, so as to limit the third rotating member 133 of the first rotating mechanism 130 in the direction of the main body 120 pointing towards the third rotating member 133 of the first rotating mechanism 130, thereby making it easy to assemble the main body 120, the third rotating member 133 of the first rotating mechanism 130, and the limiting member 1300.

[0138] The limiting member 1300 has a limiting hole 1310, the fifth connecting shaft 1361 passes through the limiting hole 1310 and the third connecting hole 1331, and is fixed to the main body 120.

[0139] In this embodiment, the limiting member 1300 has a limiting hole 1310, and the fifth connecting shaft 1361 is fixed to the main body 120 through the limiting hole 1310 and the third connecting hole 1331, thereby making the fifth connecting shaft 1361 rotatably connected to the main body 120. This method is simple and easy to implement.

[0140] Please continue reading. Figures 29 to 37 The third rotating member 133 of the first rotating mechanism 130 and the connecting member 134 of the first rotating mechanism 130 are connected by a limiting groove 1342 and a limiting part 1332. The limiting groove 1342 is disposed in one of the third rotating member 133 and the connecting member 134 of the first rotating mechanism 130, and the limiting part 1332 is disposed in the other of the third rotating member 133 and the connecting member 134 of the first rotating mechanism 130.

[0141] In the schematic diagram of this embodiment, the connecting member 134 of the first rotating mechanism 130 has the limiting groove 1342, and the third rotating member 133 of the first rotating mechanism 130 has the limiting portion 1332, as an example. It will be understood that in other embodiments, the connecting member 134 of the first rotating mechanism 130 has the limiting portion 1332, and the third rotating member 133 of the first rotating mechanism 130 has the limiting groove 1342.

[0142] When the connecting member 134 of the first rotating mechanism 130 is folded or unfolded relative to the main body 120, the limiting part 1332 slides in the limiting groove 1342.

[0143] Please see Figure 30 and Figure 34 In this embodiment, the limiting groove 1342 has a first limiting segment 134a and a second limiting segment 134b located at opposite ends. The first limiting segment 134a is farther away from the main body 120 than the second limiting segment 134b. When the first support member 111 and the second support member 111' are in a folded state, one end of the limiting portion 1332 is located in the second limiting segment 134b; when the first support member 111 and the second support member 111' are in a flattened state, one end of the limiting portion 1332 is located in the first limiting segment 134a.

[0144] When the first support member 111 and the second support member 111' are in a folded state, one end of the limiting part 1332 is located at the second limiting segment 134b, which can prevent the first support member 111 from being further folded and damaging the screen 30. When the first support member 111 and the second support member 111' are in a flattened state, one end of the limiting part 1332 is located at the first limiting segment 134a, which can prevent the first support member 111 from being folded back and damaging the screen 30.

[0145] Please continue reading. Figures 29 to 37 The third rotating member 133 of the first rotating mechanism 130 and the connecting member 134 of the first rotating mechanism 130 are connected by a limiting groove 1342 and a limiting part 1332. The limiting groove 1342 is disposed in one of the third rotating member 133 and the connecting member 134 of the first rotating mechanism 130, and the limiting part 1332 is disposed in the other of the third rotating member 133 and the connecting member 134 of the first rotating mechanism 130.

[0146] In the schematic diagram of this embodiment, the connecting member 134 of the first rotating mechanism 130 has the limiting groove 1342, and the third rotating member 133 of the first rotating mechanism 130 has the limiting portion 1332, as an example. It will be understood that in other embodiments, the connecting member 134 of the first rotating mechanism 130 has the limiting portion 1332, and the third rotating member 133 of the first rotating mechanism 130 has the limiting groove 1342.

[0147] When the connecting member 134 of the first rotating mechanism 130 is folded or unfolded relative to the main body 120, the limiting part 1332 slides in the limiting groove 1342.

[0148] Please see Figure 30 and Figure 34 In this embodiment, the limiting groove 1342 has a first limiting segment 134a and a second limiting segment 134b located at opposite ends. The first limiting segment 134a is farther away from the main body 120 than the second limiting segment 134b. When the first support member 111 and the second support member 111' are in a folded state, one end of the limiting portion 1332 is located in the second limiting segment 134b; when the first support member 111 and the second support member 111' are in a flattened state, one end of the limiting portion 1332 is located in the first limiting segment 134a.

[0149] When the first support member 111 and the second support member 111' are in a folded state, one end of the limiting part 1332 is located at the second limiting segment 134b, which can prevent the first support member 111 from being further folded and damaging the screen 30. When the first support member 111 and the second support member 111' are in a flattened state, one end of the limiting part 1332 is located at the first limiting segment 134a, which can prevent the first support member 111 from being folded back and damaging the screen 30.

[0150] Please refer to the following: Figures 38 to 41 , Figure 38 for Figure 4 A schematic diagram of the cooperation between the connecting member and the first support member in the first rotating mechanism of the folding device shown in the figure; Figure 39 for Figure 38 An exploded perspective view of the connecting member and the first support member of the first rotating mechanism in the diagram. Figure 40 for Figure 39 An exploded perspective view of the connecting member and the first support member of the first rotating mechanism in the diagram. Figure 41 for Figure 38 A cross-sectional view along line EE. The connecting member 134 of the first rotating mechanism 130 is connected to the first support member 111 through a second arc groove 111b and a second arc rail 1343. The second arc groove 111b is provided in one of the connecting member 134 and the first support member 111 of the first rotating mechanism 130, and the second arc rail 1343 is provided in the other of the connecting member 134 and the first support member 111 of the first rotating mechanism 130.

[0151] In the schematic diagram of this embodiment, the second arc groove 111b is disposed on the first support member 111, and the second arc rail 1343 is disposed on the connector 134 of the first rotating mechanism 130 as an example. It can be understood that in other embodiments, the second arc rail 1343 is disposed on the first support member 111, and the second arc groove 111b is disposed on the connector 134 of the first rotating mechanism 130.

[0152] In this embodiment, the connecting member 134 of the first rotating mechanism 130 and the first support member 111 have two pairs of second arc grooves 111b and second arc rails 1343. One pair of second arc grooves 111b and second arc rails 1343 are spaced apart from the other pair of second arc grooves 111b and second arc rails 1343 to improve the stability of the first support member 111 when rotating relative to the connecting member 134 of the first rotating mechanism 130.

[0153] In this embodiment, the connecting member 134 of the first rotating mechanism 130 has two opposing first surfaces 1347 and a second surface 1348. The second surface 1348 connects the two first surfaces 1347, and the second surface 1348 is the surface of the first surface 1347 facing the first support member 111. Both first surfaces 1347 are provided with second arc tracks 1343. Correspondingly, the first support member 111 is provided with two second arc grooves 111b. One second arc groove 111b mates with one second arc track 1343, and different second arc grooves 111b mate with different second arc tracks 1343.

[0154] In other embodiments, the connecting member 134 of the first rotating mechanism 130 and the first support member 111 have two pairs of second arc grooves 111b and second arc rails 1343, and further include the following forms: the connecting member 134 of the first rotating mechanism 130 is provided with two second arc grooves 111b, and correspondingly, the first support member 111 is provided with two second arc rails 1343; or, the connecting member 134 of the first rotating mechanism 130 is provided with one second arc rail 1343 and one second arc groove 111b, and correspondingly, the first support member 111 is provided with one second arc groove 111b and one second arc rail 1343, the second arc groove 111b on the first support member 111 cooperates with the second arc rail 1343 on the connecting member 134 of the first rotating mechanism 130, and the second arc rail 1343 on the first support member 111 cooperates with the second arc groove 111b on the connecting member 134 of the first rotating mechanism 130. Understandably, in other embodiments, the connector 134 of the first rotating mechanism 130 and the first support member 111 have three or more pairs of second arcuate grooves 111b and second arcuate rails 1343. Each pair of second arcuate grooves 111b and second arcuate rails 1343 is spaced apart from the other pairs of second arcuate grooves 111b and second arcuate rails 1343 to improve the stability of the first support member 111 when rotating relative to the connector 134 of the first rotating mechanism 130.

[0155] In this embodiment, the connecting member 134 of the first rotating mechanism 130 and the first support member 111 are connected by a second arc groove 111b and a second arc rail 1343. On the one hand, this allows the connecting member 134 of the first rotating mechanism 130 to be rotatably connected to the first support member 111. On the other hand, it is not convenient to process the second arc groove 111b and the second arc rail 1343 on the connecting member 134 of the first rotating mechanism 130 and the first support member 111, which facilitates the assembly between the connecting member 134 of the first rotating mechanism 130 and the first support member 111, making the assembled folding device 100 more compact.

[0156] Furthermore, the rotation axis of the second arc groove 111b and the second arc rail 1343 when they rotate relative to each other is a virtual axis. In other words, the second arc groove 111b and the second arc rail 1343 rotate around the virtual axis when they rotate relative to each other. Compared with a physical axis, the position of the virtual axis can be designed as needed. The rotation axis of the connecting member 134 of the first rotating mechanism 130 and the first support member 111 is closer to the theoretically designed position, thereby enabling the connecting member 134 of the first rotating mechanism 130 and the first support member 111 to have a higher precision motion trajectory when they rotate. In addition, during the movement of the folding device 100 or when the folding device 100 is in a flattened or folded state, there will be no interference with the screen 30 carried by the folding device 100.

[0157] Please refer to further information. Figures 4 to 6 As shown in the accompanying drawings, the folding device 100 also includes a decorative element 1400. The decorative element 1400 is disposed on one side of the main body 120 and is used to decorate the main body 120.

[0158] The decorative element 1400 (also called a back cover) decorates the main body 120, allowing at least one of the first rotating member 131, the second rotating member 132, and the third rotating member 133 to be exposed when the folding device 100 is folded or unfolded. Understandably, since the decorative element 1400 is disposed on one side of the main body 120, it also protects the main body 120. In other embodiments, the decorative element 1400 may also be provided with decorative patterns, etc., to give it a more eye-catching decorative effect.

[0159] The decorative element 1400 of the folding device 100 includes a first decorative portion 141 and a second decorative portion 142. The second decorative portion 142 is bent and connected to the first decorative portion 141 to form an accommodating space 140a. The accommodating space 140a is used to accommodate at least a portion of the main body 120. In this embodiment, there are two second decorative portions 142, which are arranged opposite to each other and are both bent and connected to the first decorative portion 141. Both second decorative portions 142 are located on the same side of the first decorative portion 141 and are arranged opposite to each other. When the folding device 100 is in a flattened state, the first support member 111 and the second support member 111' are located outside the two second decorative portions 142, respectively. In other words, when the folding device 100 is in a flattened state, the first support member 111 is located outside one second decorative portion 142, and the second support member 111' is located outside the other second decorative portion 142.

[0160] When the first support member 111 and the second support member 111' are in a flattened state, the first support member 111 and the second support member 111' are respectively located outside the second decorative part 142. That is, the second decorative part 142 is located in the gap between the first support member 111 and the main body 120, and the second decorative part 142 is located in the gap between the second support member 111' and the main body 120. This allows the decorative part 1400 to cover the gap between the assembly formed by the first support member 111 and the connecting member 134 of the first rotating mechanism 130 and the main body 120, thereby reducing or preventing dust, moisture, etc. from entering the main body 120 and the first rotating member 131, the second rotating member 132 and the third rotating member 133 of the first rotating mechanism 130 connected to the main body 120. Furthermore, the decorative element 1400 can cover the gap between the components formed by the second support element 111' and the connector 134 of the first rotating mechanism 130 and the main body 120, thereby reducing or preventing dust, moisture, etc. from entering the main body 120 and the first rotating element 131, the second rotating element 132 and the third rotating element 133 of the first rotating mechanism 130 connected to the main body 120.

[0161] Furthermore, the decorative element 1400 can also protect the main body 120. In other embodiments, the decorative element 1400 may also be provided with decorative patterns, etc., to give the decorative element 1400 a more eye-catching decorative effect.

[0162] In one embodiment, the main body 120 is disposed within the accommodating space 140a, and the main body 120 is connected to the decorative member 1400. Optionally, the main body 120 can be connected to the state member by, but is not limited to, screwing, snap-fitting, or gluing.

[0163] It should be noted that the first rotating member 131 includes two bent parts to avoid the first decorative part 141 and the second decorative part 142 of the decorative member 1400.

[0164] It should be noted that, in this embodiment, the first rotating mechanism 130 and the second rotating mechanism 130' are illustrated as symmetrical about the axis of rotation of the folding device 100 on both sides of the main body 120. In other embodiments, the first rotating mechanism 130 and the second rotating mechanism 130' may also be asymmetrical about the axis of rotation of the folding device 100 on both sides of the main body 120. Asymmetry of the first rotating mechanism 130 and the second rotating mechanism 130' about the axis of rotation of the folding device 100 on both sides of the main body 120 includes, but is not limited to, the following embodiments. In one embodiment, the first rotating mechanism 130 and the second rotating mechanism 130' are not directly opposite each other in a direction perpendicular to the axis of the main body 120, but are offset. In another embodiment, the relative positional relationship between the first rotating member 131, the second rotating member 132, and the third rotating member 133 in the first rotating mechanism 130 is different from the relative positional relationship between the first rotating member 131, the second rotating member 132, and the third rotating member 133 in the second rotating mechanism 130'. For example, in the first rotating mechanism 130, the second rotating member 132, the first rotating member 131, and the third rotating member 133 are arranged in sequence; in the second rotating mechanism 130', the third rotating member 133, the second rotating member 132, and the first rotating member 131 are arranged in sequence; or, in the second rotating mechanism 130', the first rotating member 131, the second rotating member 132, and the third rotating member 133 are arranged in sequence.

[0165] When the second rotating mechanism 130' and the first rotating mechanism 130 are symmetrical about the rotation axis of the folding device 100 on both sides of the main body 120, it is convenient to assemble the first rotating mechanism 130 and the second rotating mechanism 130'. In addition, it also makes the screen foldable symmetrically when the supporting device carries the foldable screen.

[0166] The cooperation relationship between the second rotating mechanism 130' and the main body 120 is the same as that between the first rotating mechanism 130 and the main body 120. The cooperation relationship between the second rotating mechanism 130' and the second support member 111' is the same as that between the first rotating mechanism 130 and the first support member 111. Knowing the cooperation relationships between the components of the first rotating mechanism 130 (first rotating member 131, second rotating member 132, third rotating member 133, and connecting member 134) and the main body 120 and the first support member 111, the cooperation relationships between the components of the first rotating mechanism 130 (first rotating member 131, second rotating member 132, third rotating member 133, and connecting member 134) and the main body 120 and the second support member 111' can be obtained. However, for ease of description, the components that cooperate between the first rotating member 131 and the second support member 111' of the second rotating mechanism 130' will be renamed below. The cooperation relationships between the various components of the second rotating mechanism 130' (first rotating member 131, second rotating member 132, third rotating member 133 and connecting member 134) and the main body 120, as well as the relationships between the various components, will not be renamed.

[0167] As described above, the first rotating component 131 of the first rotating mechanism 130 is connected to the first support component 111 via a first connecting shaft 1314 and a first arc-shaped sliding groove 1113. Please continue reading. Figures 6 to 8 In this embodiment, the first rotating member 131 of the second rotating mechanism 130' and the second support member 111' are also connected by a connecting shaft and an arc-shaped groove. For descriptive purposes, the connecting shaft and the arc-shaped groove connecting the first rotating member 131 of the second rotating mechanism 130' and the second support member 111' are respectively named the first shaft 1314' and the first arc-shaped groove 1113'. In other words, the first rotating member 131 of the second rotating mechanism 130' and the second support member 111' are connected by the first shaft 1314' and the first arc-shaped groove 1113'.

[0168] The first rotating member 131 of the second rotating mechanism 130' and the second support member 111' are connected by the first shaft 1314' and the first arc-shaped groove 1113' in the same way that the first connecting member 134 of the first rotating mechanism 130 and the first support member 111 are connected by the first connecting shaft 1314 and the first arc-shaped sliding groove 1113. Given the known connection relationship between the first connecting member 134 and the first support member 111 of the first rotating mechanism 130, replacing the first connecting member 134 of the first rotating mechanism 130 with the electrical connecting member 134 of the second rotating mechanism 130', and replacing the first support member 111 with the second support member 111', will yield the connection relationship between the first connecting member 134 and the second support member 111' of the second rotating mechanism 130'.

[0169] Specifically, in this embodiment, the first rotating member 131 of the second rotating mechanism 130' and the second support member 111' are connected by a first shaft 1314' and a first arc-shaped groove 1113', so that the first rotating member 131 is slidably and rotatably connected to the second support member 111'. The first arc-shaped groove 1113' may be provided in one of the first rotating member 131 and the second support member 111', and the first shaft 1314' may be fixed to the other of the first rotating member 131 and the second support member 111' of the second rotating mechanism 130'. The first rotating member 131 of the second rotating mechanism 130' and the second support member 111' are connected by a first shaft 1314' and a first arc-shaped groove 1113'. This allows the second support member 111' to have both displacement and angular changes with the first rotating member 131 of the second rotating mechanism 130' when the second support member 111' moves relative to the main body 120. Therefore, the second support member 111' has a large degree of freedom during movement, which helps to reduce the bending stress of the second support member 111' on the screen it supports, thereby ensuring that the screen is not easily damaged.

[0170] In this embodiment, the first arc-shaped groove 1113' is disposed on the second support member 111', and the first shaft 1314' is fixed to the first rotating member 131. Compared to the first arc-shaped groove 1113' being disposed on the first connecting member 134, and the first connecting member 134 being fixed to the second support member 111', in this embodiment, the first arc-shaped groove 1113' being disposed on the second support member 111', and the first shaft 1314' being fixed to the first rotating member 131, is beneficial for miniaturizing the size of the first rotating member 131 of the second rotating mechanism 130', thereby facilitating the miniaturization of the folding device 100.

[0171] Please refer to it again. Figure 10and Figure 16 The first rotating member 131 of the second rotating mechanism 130' has a first hole 1311', the second supporting member 111' of the second rotating mechanism 130' has a connected second supporting body portion 1111' and a second connecting portion 1112', the second connecting portion 1112' has a first arc-shaped groove 1113', one end of the first shaft 1314' passes through the first hole 1311', and the other end of the first shaft 1314' is located in the first arc-shaped groove 1113' of the second connecting portion 1112'.

[0172] The first rotating member 131 of the second rotating mechanism 130' has a connecting hole. For ease of description, the connecting hole of the first rotating member 131 of the second rotating mechanism 130' is named the first hole 1311'. The second support member 111' has a connected second support body portion 1111' and a second connecting portion 1112'. The second connecting portion 1112' has the first arc-shaped groove 1113. One end of the first shaft 1314' is located in the first hole 1311' and is fixed to the first rotating member 131 of the second rotating mechanism 130'. The other end of the first shaft 1314' is located in the first arc-shaped groove 1113'.

[0173] The first hole 1311' can be a through hole or a blind hole, as long as one end of the first shaft 1314' is located inside the first hole 1311' and fixed to the first rotating member 131. In the schematic diagram of this embodiment, the first hole 1311' is illustrated as a through hole. When the first hole 1311' is a through hole, it is convenient for the first shaft 1314' to be installed inside the first hole 1311'. The other end of the first shaft 1314' is located inside the first arc-shaped groove 1113' and can move within the first arc-shaped groove 1113'. When the second support member 111' moves relative to the main body 120, the other end of the first shaft 1314' can slide and rotate within the first arc-shaped groove 1113'.

[0174] The first arc-shaped groove 1113' of the second connecting portion 1112' has a first end 1114' and a second end 1115' located at opposite ends, wherein the first end 1114' is away from the main body 120 relative to the second end 1115', and when the folding device 100 is in a flattened state, the other end of the first shaft 1314' is located at the first end 1114'; when the folding device 100 is in a folded state, the other end of the first shaft 1314' is located at the second end 1115'.

[0175] The first end 1114' and the second end 1115' are the two ends of the first arc-shaped groove 1113'. The first end 1114' is further away from the main body 120 than the second end 1115'. In other words, the first end 1114' is farther away from the main body 120, and the second end 1115' is closer to the main body 120. When the folding device 100 is in the flattened state, the other end of the first shaft 1314' is located at the first end 1114', which can prevent the second support member 111' from continuing to unfold and damaging the screen. When the folding device 100 is in the folded state, the other end of the first shaft 1314' is located at the second end 1115', which can prevent the second support member 111' from folding further and damaging the screen 30.

[0176] In one embodiment, when the folding device 100 is in a flattened state, and when the other end of the first shaft 1314' is located at the first end 1114', the other end of the first shaft 1314' can abut against the sidewall of the first end 1114' that forms the first arcuate groove 1113'. In another embodiment, when the folding device 100 is in a flattened state, and when the other end of the first shaft 1314' is located at the first end 1114', there is a gap between the other end of the first shaft 1314' and the sidewall of the first end 1114' that forms the first arcuate groove 1113', to prevent the folding device 100 from failing to flatten properly due to structural tolerances or other reasons.

[0177] In one embodiment, when the folding device 100 is in a folded state, and when the other end of the first shaft 1314' is located at the second end 1115', the other end of the first shaft 1314' may abut against the sidewall of the second end 1115' that forms the first arcuate groove 1113'. In another embodiment, when the folding device 100 is in a flattened state, and when the other end of the first shaft 1314' is located at the second end 1115', there is a gap between the other end of the first shaft 1314' and the sidewall of the second end 1115' that forms the first arcuate groove 1113', to prevent the folding device 100 from failing to fold properly due to structural tolerances or other reasons.

[0178] Please continue reading. Figure 19 The second support body 1111' has a second support surface 111'a that is opposite to the second connecting part 1112'. When the folding device 100 is in a flattened state, the distance between the first shaft 1314' and the second support surface 111'a is a third distance d. 03When the folding device 100 is in the folded state, the distance between the first shaft 1314' and the second support surface 111'a is the fourth distance d. 04 , where the third distance d 03 Greater than the fourth distance d 04 .

[0179] Since the first shaft 1314' is located at the first end 1114' when the folding device 100 is in the flattened state, and the first shaft 1314' is located at the second end 1115' when the folding device 100 is in the folded state, the distance between the first end 1114' and the second support surface 111'a (i.e., the third distance d) is... 03 The distance d is greater than the distance between the second end 1115' and the second support surface 111'a (i.e., the third distance d). 04 When the folding device 100 is in a flattened state, and viewed from an upward angle with the second support surface 111'a facing upwards, the first end 1114' is lower than the second end 1115'. In this embodiment, the third distance is greater than the fourth distance to ensure that when the folding device 100 starts moving from the flattened state, the second support member 111' rotates counterclockwise, thereby enabling the second support member 111' to fold, thus allowing the folding device 100 to enter the folded state.

[0180] Please continue reading. Figures 10 to 14 The first arc-shaped groove 1113' also has a connecting section 1116', which is connected between the first end 1114' and the second end 1115', and the connecting section 1116' protrudes in a direction away from the second support surface 111'a.

[0181] The connecting segment 1116' is located between the first end 1114' and the second end 1115', and connects the first end 1114' and the second end 1115'. The connecting segment 1116' protrudes in a direction away from the second support surface 111'a. Therefore, when the folding device 100 switches from the unfolded state to the folded state or from the folded state to the unfolded state, the movement speed of the second support member 111' is slower than that of the first connecting member 134 of the second rotating mechanism 130'. If the second support member 111' moves faster than the first connector 134 of the second active mechanism, then the lowest part of the screen 30 supported by the folding device 100 in the bent state (from the illustrated perspective, i.e., the part corresponding to the axis of the folding device 100) will move more in the direction away from the second support surface 111'a compared to the original position of that part in the flattened state. This makes the screen 30 more prone to interference with decorative parts located on the side of the screen 30 away from the second support member 111', and the screen 30 is easily damaged. In the folding device 100 provided in this embodiment, the connecting segment 1116' protrudes in the direction away from the second support surface 111'a, thereby preventing damage to the screen 30 supported by the folding device 100 caused by the second support member 111' moving too fast.

[0182] The following describes the cooperation relationship between the first rotating component 131 of the second rotating mechanism 130' and the main body 120. The relationship between the first rotating component 131 of the second rotating mechanism 130' and the main body 120 is the same as that between the first rotating component 131 of the first rotating mechanism 130 and the main body 120. Knowing the cooperation relationship between the first rotating component 131 of the first rotating mechanism 130 and the main body 120, the first rotating component 131 of the first rotating mechanism 130 can be replaced with the first rotating component 131 of the second rotating mechanism 130' to obtain the cooperation relationship between the first rotating component 131 of the second rotating mechanism 130' and the main body 120. Here, the cooperation relationship between the first rotating component 131 of the second rotating mechanism 130' and the main body 120 is briefly described as follows; the remaining details can be referred to the previous description of the cooperation relationship between the first rotating component 131 of the first rotating mechanism 130 and the main body 120.

[0183] Please see Figures 16 to 18 The first rotating component 131 of the second rotating mechanism 130' is connected to the main body 120 through a second shaft 1315' and a second arc-shaped groove 121'.

[0184] In this embodiment, the first rotating member 131 of the second rotating mechanism 130' is connected to the main body 120 via a second shaft 1315' and a second arc-shaped groove 121', allowing the first rotating member 131 to slide and rotatably connect to the main body 120. The second shaft 1315' is disposed on one of the first rotating member 131 of the second rotating mechanism 130' and the main body 120, and the second arc-shaped groove 121' is disposed on the other. The second shaft 1315' and the second arc-shaped groove 121' are connected to each other, allowing the first rotating member 131 to slide and rotatably connect to the main body 120. The first rotating member 131 of the second rotating mechanism 130' is connected to the main body 120 via a second shaft 1315' and a second arc-shaped groove 121'. This allows the first rotating member 131 of the second rotating mechanism 130' to undergo both displacement and angular changes relative to the main body 120 during movement, resulting in a large degree of freedom for the first rotating member 131. Because the first rotating member 131 is slidably and rotatably connected to the first support member 111, this large degree of freedom further increases the degree of freedom of the first support member 111. This further helps to reduce the bending stress on the screen 30 supported by the first support member 111, thus ensuring that the screen 30 is not easily damaged.

[0185] In this embodiment, the first rotating member 131 of the second rotating mechanism 130' has a second shaft 1315', and the main body 120 has a second arcuate groove 121'. In another embodiment, the first rotating member 131 has a second arcuate groove 121', and the main body 120 has a second rotating shaft. It is acceptable as long as the first rotating member 131 of the second rotating mechanism 130' and the main body 120 can be slidably and rotatably connected. In this embodiment, because the main body 120 has a relatively large thickness, the second arcuate groove 121' is provided on the main body 120, and the second shaft 1315' is fixed to the first rotating member 131 of the second rotating mechanism 130'. This allows the first rotating member 131 to have a smaller thickness, thus facilitating the miniaturization of the first rotating member 131 and reducing the thickness of the folding device 100 when it is in the unfolded state.

[0186] Please see Figure 16The first rotating member 131 of the second rotating mechanism 130' has a second hole 1312'. The main body 120 has a first receiving space 120a, and at least one of the two opposite sidewalls of the main body 120 forming the first receiving space 120a is provided with a second arc-shaped groove 121'. The second shaft 1315' is located in the second hole 1312' and fixed to the first rotating member 131 of the second rotating mechanism 130', and cooperates with the second arc-shaped groove 121'.

[0187] The following describes the cooperation relationship between the first rotating component 131 of the second rotating mechanism 130' and the connecting component 134 of the second rotating mechanism 130'. The relationship between the first rotating component 131 of the second rotating mechanism 130' and the connecting component 134 of the second rotating mechanism 130' is the same as the cooperation relationship between the first rotating component 131 of the first rotating mechanism 130 and the connecting component 134 of the first rotating mechanism 130. Knowing the cooperation relationship between the first rotating component 131 of the first rotating mechanism 130 and the connecting component 134 of the first rotating mechanism 130, the cooperation relationship between the first rotating component 131 of the first rotating mechanism 130 and the connecting component 134 of the second rotating mechanism 130' can be obtained by replacing the first rotating component 131 of the first rotating mechanism 130' with the first rotating component 131 of the second rotating mechanism 130', and by replacing the connecting component 134 of the first rotating mechanism 130' with the connecting component 134 of the second rotating mechanism 130'. Here, the cooperation relationship between the first rotating member 131 of the second rotating mechanism 130' and the connecting member 134 of the second rotating mechanism 130' is briefly described as follows. The rest can be referred to the previous description of the cooperation relationship between the first rotating member 131 of the first rotating mechanism 130 and the connecting member 134 of the first rotating mechanism 130.

[0188] Please continue reading. Figure 18 The first rotating component 131 of the second rotating mechanism 130' and the connecting component 134 of the second rotating mechanism 130' are connected by a third shaft 1316' and a third hole 1313'.

[0189] Accordingly, the cooperation relationship between the second connecting member 134 of the second rotating mechanism 130' and the connecting member 134 of the second rotating mechanism 130' is the same as the cooperation relationship between the second connecting member 134 of the first rotating mechanism 130 and the connecting member 134 of the first rotating mechanism 130. Knowing the cooperation relationship between the second connecting member 134 of the first rotating mechanism 130 and the connecting member 134 of the first rotating mechanism 130, the cooperation relationship between the second connecting member 134 of the second rotating mechanism 130' and the connecting member 134 of the second rotating mechanism 130' can be obtained by replacing the first connecting member 134 of the first rotating mechanism 130 with the first connecting member 134 of the second rotating mechanism 130', which will not be elaborated further here.

[0190] The connection relationship between the third rotating component 133 of the second rotating mechanism 130' and the main body 120 is the same as the cooperation relationship between the third rotating component 133 of the first rotating mechanism 130 and the main body 120. Knowing the cooperation relationship between the third rotating component 133 of the first rotating mechanism 130 and the main body 120, replacing the third rotating component 133 of the first rotating mechanism 130 with the third rotating component 133 of the second rotating mechanism 130' yields the cooperation relationship between the third rotating component 133 of the second rotating mechanism 130' and the main body 120. Correspondingly, the cooperation relationship between the third rotating component 133 of the second rotating mechanism 130' and the connecting component 134 of the second rotating mechanism 130' is the same as the cooperation relationship between the third rotating component 133 of the first rotating mechanism 130 and the connecting component 134 of the first rotating mechanism 130. Knowing the cooperation relationship between the third rotating component 133 of the first rotating mechanism 130 and the connecting component 134 of the first rotating mechanism 130, by replacing the third rotating component 133 of the first rotating mechanism 130 with the third rotating component 133 of the second rotating mechanism 130', and by replacing the connecting component 134 of the first rotating mechanism 130 with the connecting component 134 of the second rotating mechanism 130', the cooperation relationship between the third rotating component 133 of the second rotating mechanism 130' and the connecting component 134 of the second rotating mechanism 130' can be obtained.

[0191] The cooperation relationship between the connector 134 of the second rotating mechanism 130' and the second support member 111' is the same as the cooperation relationship between the connector 134 of the first rotating mechanism 130 and the first support member 111. Knowing the cooperation relationship between the connector 134 of the first rotating mechanism 130 and the first support member 111, by replacing the connector 134 of the first rotating mechanism 130 with the connector 134 of the second rotating mechanism 130', and by replacing the first support member 111 with the second support member 111', the cooperation relationship between the connector 134 of the second rotating mechanism 130' and the second support member 111' can be obtained.

[0192] Please refer to the following: Figure 42 , Figure 42 for Figure 4 The diagram illustrates the first and second rotation axes in the folding device. The main body 120 has an end face (i.e., first end face 123) adjacent to the first support member 111 when the folding device 100 is in the folded state. In the same rotation mechanism: the first rotation axis L1 between the second rotating member 132 and the main body 120 is parallel to the second rotation axis L2 between the third rotating member 133 and the main body 120, and the first rotation axis L1 is closer to the end face than the second rotation axis L2.

[0193] Wherein, the first rotation axis L1 is parallel to the second rotation axis L2, meaning that the extension direction of the first rotation axis L1 is the same as the extension direction of the second rotation axis L2, and there is a certain distance between the first rotation axis L1 and the second rotation axis L2. In other words, the first rotation axis L1 and the second rotation axis L2 are parallel to each other and do not coincide. The above design allows the connecting member 134 to be restricted from rotating relative to the second rotating member 132 and the third rotating member 133 when the folding device 100 is in a stationary state (i.e., when the folding device 100 is not rotating). In other words, the connecting member 134 is relatively stationary relative to the second rotating member 132 and the third rotating member 133, thereby improving the structural stability of the folding device 100. It should be noted that when the folding device 100 is in motion, the rotation of the connecting member 134 can still directly or indirectly drive the second rotating member 132 and the third rotating member 133 to rotate.

[0194] Furthermore, the first rotation axis L1 between the second rotating member 132 and the main body 120 is parallel to the second rotation axis L2 between the third rotating member 133 and the main body 120. The first rotation axis L1 is closer to the end face (i.e., the first end face 123) than the second rotation axis L2. Therefore, interference between the screen 30 and the main body 120 is avoided when the folding device 100 is folded, thereby enabling the folding device 100 to fold normally.

[0195] This application also provides a folding housing 10, which includes two housings 500 and a folding device 100 as described in any of the preceding embodiments. The folding device 100 is described above and will not be repeated here.
