[0100] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments.

[0101] Please refer to Figure 29 andFigure 1 , Figure 2 A front view of the foldable electronic device 1 in an unfolded state is shown, Figure 1 A front view of the foldable electronic device 1 in a folded state is shown. Figure 2 A front view of the foldable electronic device 1 in a folded state is shown.

[0102] The electronic device 1 comprises a folding mechanism 011, a first side plate 012, a second side plate 013, and a flexible display screen 02. The first side plate 012 and the second side plate 013 are respectively connected to two sides of the folding mechanism 011 and can rotate between a folded state and an unfolded state based on the folding mechanism 011. The flexible display screen 02 is arranged on the first side plate 012 and the second side plate 013, and the position of a flexible deformation part 021 of the flexible display screen 02 corresponds to the position of the folding mechanism 011. The flexible deformation part 021 can be bent to enable the flexible display screen 02 to be folded or unfolded with the rotation of the first side plate 012 and the second side plate 013.

[0103] Referring to Figure 1 When the electronic device 1 is in an unfolded state, the included angle between the first side plate 012 and the second side plate 013 is substantially 180°, the flexible display screen 02 is substantially flat, and the flexible deformation part 021 of the flexible display screen 02 is substantially flat.

[0104] Referring to Figure 1 When the electronic device 1 is in a folded state, the included angle between the first side plate 012 and the second side plate 013 is substantially 0°, and the flexible deformation part 021 of the flexible display screen 02 is bent.

[0105] During the production and use of the electronic device 1, it may be impacted by external objects or fall, causing the flexible display screen 02 to be easily damaged. In particular, the flexible deformation part 021 of the flexible display screen 02 has relatively low structural strength and is more likely to be damaged when subjected to external forces, as it needs to be bent. For example, when the electronic device 1 is subjected to external forces, the flexible deformation part 021 of the flexible display screen 02 and the folding mechanism 011 may collide with each other, which can easily cause the flexible deformation part 021 to be damaged and fail.

[0106] Exemplarily, referring to Figure 2 , Figure 3 A front view of the foldable electronic device 1 in a folded state is shown. Figure 3A local structure schematic diagram of the electronic device 1 in the unfolded state is shown. The flexible display screen 02 is connected with a support assembly 03 on one side of the folding mechanism 011, the support assembly 03 includes two support plates 031 and a rotating piece 032 arranged between the two support plates 031, the position of the rotating piece 032 corresponds to the position of the flexible deformation part 021 of the flexible display screen 02, and the two support plates 031 can be relatively rotated based on the rotating piece 032 therebetween, so that the support assembly 03 can be folded or unfolded synchronously with the flexible display screen 02. The support assembly 03 can play a supporting and reinforcing role on the flexible display screen 02.

[0107] The rotating piece 032 includes a plurality of strip-shaped bodies 0321 arranged side by side, and there is a gap between adjacent two strip-shaped bodies 0321. In the process of rotating the electronic device 1 from the unfolded state to the folded state, the flexible deformation part 021 of the flexible display screen 02 is gradually bent, and the plurality of strip-shaped bodies 0321 are gradually gathered to maintain the bending shape of the flexible deformation part 021. In the process of rotating the electronic device 1 from the folded state to the unfolded state, the flexible deformation part 021 of the flexible display screen 02 is gradually flattened, and the plurality of strip-shaped bodies 0321 are gradually unfolded to maintain the flat shape of the flexible deformation part 021.

[0108] When the electronic device 1 is subjected to external force, the flexible deformation part 021 and the rotating piece 032 are easy to collide with the folding mechanism 011, and the strip-shaped body 0321 of the rotating piece 032 is usually a hard structure of metal material to better support the flexible deformation part 021, which causes the flexible deformation part 021 to be easy to be damaged and invalid, affecting the service life of the electronic device 1.

[0109] Therefore, the embodiments of the present application provide a folding assembly and a terminal device comprising the folding assembly, which can improve the technical problem that the flexible deformation part of the flexible display screen is easy to be damaged when subjected to external force in the related art, and improve the reliability.

[0110] The terminal device provided by the embodiments of the present application belongs to a foldable electronic device, that is, an electronic device capable of folding and unfolding. The terminal device can be a mobile phone, a tablet computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a wearable device (such as a watch), a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, etc., but is not limited thereto.

[0111] Please refer to Figure 1 and Figure 4 , Figure 5Fig. 1 shows a structural schematic diagram of a terminal device 1000 in an unfolded state according to some embodiments of the present application, Figure 4 Fig. 1 shows a structural schematic diagram of a terminal device 1000 in an unfolded state according to some embodiments of the present application, Figure 5 Fig. 1 shows a structural schematic diagram of a terminal device 1000 in an unfolded state according to some embodiments of the present application,

[0112] The terminal device 1000 comprises a folding assembly 100, a pivot mechanism 200, a first housing 300, a second housing 400, and a folding screen 500, wherein:

[0113] The first housing 300 and the second housing 400 are rotationally connected by the pivot mechanism 200; that is, the first housing 300 and the second housing 400 can relatively rotate based on the pivot mechanism 200 to be relatively close to each other and rotate to the folded state, and relatively far away from each other and rotate to the unfolded state.

[0114] It can be understood that the first housing 300 and the second housing 400 can each be a middle frame, and the specific shape and structure can be set as needed. The pivot mechanism 200 can be a structure in various forms, as long as it can allow the first housing 300 and the second housing 400 connected thereto to relatively rotate.

[0115] The folding screen 500 is arranged on the first housing 300 and the second housing 400 and can be folded or unfolded with the rotation of the first housing 300 and the second housing 400. The position of the foldable part 510 of the folding screen 500 corresponds to the position of the pivot mechanism 200. The foldable part 510 is a part that can be bent and has flexibility, so that when the first housing 300 and the second housing 400 relatively rotate, the folding screen 500 can be folded by the foldable part 510 to realize folding. When the folding screen 500 is in the folded state, the foldable part 510 can be in the shape of a water drop or a U shape, but is not limited to this shape.

[0116] It can be understood that the screen part of the folding screen 500 corresponding to the first housing 300 can have flexibility or rigidity; the screen part of the folding screen 500 corresponding to the second housing 400 can have flexibility or rigidity.

[0117] The folding assembly 100 is connected to the back of the folding screen 500, that is, between the folding screen 500 and the pivot mechanism 200. The folding assembly 100 can be folded or unfolded synchronously with the folding or unfolding of the folding screen 500. Among them, the back of the folding screen 500 is the side facing the pivot mechanism 200, which can also be regarded as the non-display side of the folding screen 500; the front of the folding screen 500 is the side facing away from the pivot mechanism 200, which is the display side of the folding screen 500 for displaying images.

[0118] When the terminal device 1000 is in the unfolded state, the folding screen 500 and the folding assembly 100 are also in the unfolded state, and the first shell 300 and the second shell 400 are substantially in the same plane, that is, the included angle between the first shell 300 and the second shell 400 is substantially 180°. At this time, the folding screen 500 is substantially flat, so that the terminal device 1000 has a larger display area. It should be understood that when the terminal device 1000 is in the unfolded state, the included angle between the first shell 300 and the second shell 400 is not limited to be absolutely 180°; the included angle between the first shell 300 and the second shell 400 can also be greater than or less than 180°, but close to 180°, for example, the range of the included angle can be 165° to 190° (for example, 170°, 173°, 175°, 182°, 185°, etc., but not limited thereto), and the unfolding of the folding screen 500 can also be achieved.

[0119] When the terminal device 1000 is in the folded state, the folding screen 500 and the folding assembly 100 are also in the folded state, and the first shell 300 and the second shell 400 are substantially parallel, that is, the included angle between the first shell 300 and the second shell 400 is substantially 0°. At this time, the folding screen 500 is folded through the foldable part 510 thereof, so as to facilitate the storage of the terminal device 1000. It should be understood that when the terminal device 1000 is in the folded state, the first shell 300 and the second shell 400 are not absolutely parallel, and the included angle between the first shell 300 and the second shell 400 can also be greater than 0°, but close to 0°, for example, the range of the included angle can be 0° to 15° (for example, 1°, 2°, 3°, 5°, 10°, etc., but not limited thereto), and the folding of the folding screen 500 can also be achieved.

[0120] In some embodiments, referring to Figure 4 , the terminal device 1000 can be an inner folding terminal device, and the folding screen 500 is an inner folding folding screen. After the folding screen 500 is folded, the folding screen 500 is located on the inner side of the folding assembly 100.

[0121] Of course, in other embodiments, the terminal device 1000 can also be an outer folding terminal device, and the folding screen 500 is an outer folding folding screen. After the folding screen 500 is folded, the display surface of the folding screen 500 is exposed, and the folding assembly 100 is located on the inner side of the folding screen 500.

[0122] In some embodiments, referring to Figure 4The rotating shaft mechanism 200 comprises a shaft cover 210, a base 220, a support door plate 230, a first swing arm 240 and a second swing arm 250. The base 220 is arranged on the shaft cover 210, and the base 220 can provide support and mounting for the support door plate 230, the first swing arm 240 and the second swing arm 250. The support door plate 230 is arranged on the base 220 and can be used to support the foldable part 510 of the foldable screen 500. The first swing arm 240 and the second swing arm 250 are respectively rotatably connected to the two sides of the base 220, so that the base 220 can be rotated to a folded state or an unfolded state. The first swing arm 240 is connected to the first housing 300, and the second swing arm 250 is connected to the second housing 400, so that when the first housing 300 and the second housing 400 rotate, the first swing arm 240 and the second swing arm 250 rotate simultaneously.

[0123] When the terminal device 1000 is in the unfolded state, the support door plate 230, the first swing arm 240 and the second swing arm 250 can all support the foldable part 510 of the foldable screen 500, which helps the foldable part 510 to be stably in a flat state. When the terminal device 1000 is in the folded state, the first swing arm 240 and the second swing arm 250 can rotate based on the base 220 and move towards each other, and a containing space can be formed between the support door plate 230, the first swing arm 240 and the second swing arm 250, so as to contain the bent foldable part 510.

[0124] Optionally, the first swing arm 240 and the second swing arm 250 can be connected and matched with the base 220 in various ways.

[0125] For example, the base 220 is provided with a sliding groove on each side, and the first swing arm 240 and the second swing arm 250 are each provided with a sliding rail, and the first swing arm 240 and the second swing arm 250 are respectively slidably matched with the sliding groove through the sliding rail, so that when the first swing arm 240 and the second swing arm 250 rotate based on the base 220, the sliding rail slides along the track of the sliding groove.

[0126] For example, the first swing arm 240 and the second swing arm 250 can also be respectively connected with the base 220 through a rotating shaft and can drive the support door plate 230 to ascend and descend. When the first swing arm 240 and the second swing arm 250 are rotated to the unfolded state, the support door plate 230 is simultaneously driven to ascend (move towards the foldable part 510) to support the foldable part 510, and when the first swing arm 240 and the second swing arm 250 are rotated to the folded state, the support door plate 230 is driven to descend (move away from the foldable part 510) to avoid the bent foldable part 510.

[0127] In the following, the folding assembly 100 provided by the embodiment of the present application will be introduced and described.

[0128] Please refer to Figure 5 , Figure 5 to Figure 7Fig. 2 shows a perspective view of the folding assembly 100 in the unfolded state according to some embodiments of the present application, Figure 6 Fig. 3 shows a perspective view of the folding assembly 100 in the folded state according to some embodiments of the present application, Figure 7 Fig. 3 shows a perspective view of the folding assembly 100 in the folded state according to some embodiments of the present application, The folding assembly 100 comprises a first support 10, a second support 20, and a folding piece 30. The second support 20 is arranged in a spaced manner with the first support 10. The folding piece 30 is arranged between the first support 10 and the second support 20. The first support 10 and the second support 20 can rotate relative to the folding piece 30 to switch the folding assembly 100 between the unfolded state and the folded state. That is, the folding piece 30 itself can be bent or folded, so that the first support 10 and the second support 20 on both sides of the folding piece 30 can rotate with the folding piece 30 as a whole. The folding piece 30 comprises an elastic body 31 for buffering external force.

[0129] The first support 10 and the second support 20 are connected to the back of the folding screen 500 and can support the folding screen 500, thereby stabilizing the folding screen 500 and enhancing the folding screen 500. Optionally, the first support 10 and the second support 20 can be in the form of a sheet, a plate, or a layer, so as to be attached to the back of the folding screen 500. The first support 10 and the second support 20 can be made of a variety of hard materials, such as metal materials (e.g., stainless steel, etc.), alloys, etc., but are not limited thereto. The first support 10 and the second support 20 can be of the same shape or different shapes.

[0130] The folding piece 30 is located between the foldable part 510 and the rotating shaft mechanism 200, and the elastic body 31 is also located between the foldable part 510 and the rotating shaft mechanism 200. The folding piece 30 can bend or unfold synchronously with the foldable part 510, thereby supporting the foldable part 510. The folding piece 30 can be connected to the first support 10 and the second support 20, or can not be directly connected to at least one of the first support 10 and the second support 20 (e.g., there is a gap).

[0131] The elastic body 31 refers to a structure body with elasticity, which can be elastically deformed. The elastic body 31 can include a soft material to have flexibility, which facilitates the bending deformation of the folding piece 30. For example, the elastic body 31 can be a structure body including a polymer with elasticity, where the polymer with elasticity can be rubber, silicone, soft PVC (Polyvinyl chloride), TPE (Thermoplastic Elastomer), TPU (Thermoplastic Urethane), TPR (Thermo-Plastic-Rubber material), TPV (Thermoplastic Vulcanizate), etc., but is not limited thereto. The elastic body 31 can have a structure in various shapes, for example, can be a connected integral structure, or can be a discrete structure including a plurality of sub-elastic bodies.

[0132] Referring to Figure 6 When the folding assembly 100 is in the unfolded state, the folding assembly 100 is substantially flat, and the first support 10 and the second support 20 are substantially in the same plane, i.e., the included angle between the first support 10 and the second support 20 is substantially 180°. It should be understood that when the folding assembly 100 is in the unfolded state, the included angle between the first support 10 and the second support 20 is not limited to be absolutely 180°; the included angle between the first support 10 and the second support 20 can also be greater than or less than 180°, but close to 180°, for example, the range of the included angle can be 165° to 190° (for example, 170°, 173°, 175°, 182°, 185°, etc., but is not limited thereto).

[0133] Referring to Figure 6 When the folding assembly 100 is in the folded state, the foldable part 510 is bent to arrange the first support 10 and the second support 20 oppositely. In some cases, the first support 10 and the second support 20 can be substantially parallel, i.e., the included angle between the first support 10 and the second support 20 is substantially 0°. It should be understood that when the folding assembly 100 is in the folded state, the first support 10 and the second support 20 are not absolutely parallel, and the included angle between the first support 10 and the second support 20 can also be greater than 0°, but close to 0°, for example, the range of the included angle can be 0° to 20° (for example, 1°, 2°, 3°, 5°, 10°, 12°, 15°, 18°, 20°, etc., but is not limited thereto).

[0134] It can be learned from the above that the folding assembly 100 provided by the embodiment of the present application can support the folding screen 500, so as to improve the stability of the form of the folding screen 500; the folding piece 30 can support the foldable part 510 of the folding screen 500, and when the foldable part 510 of the folding screen 500 is subjected to an external force (for example, the terminal device 1000 is subjected to an impact or a falling, so that the foldable part 510 and the folding piece 30 collide with the rotating shaft mechanism 200), the elastic body 31 can buffer the external force, so as to reduce the possibility of damage to the foldable part 510 of the folding screen 500.

[0135] In some embodiments, the elastic modulus of the elastic body 31 is less than the elastic modulus of the first support piece 10 and the second support piece 20, that is, the stiffness of the elastic body 31 is less than the stiffness of the first support piece 10 and the second support piece 20, so that the first support piece 10 and the second support piece 20 have a certain stiffness to support the part of the folding screen 500 other than the foldable part 510, so that the part other than the foldable part 510 can be more stably in a flat state, thereby facilitating display; and the elastic body 31 can have a certain flexibility to facilitate buffering of the external force. The elastic modulus can be represented by Young's modulus.

[0136] In some embodiments, please refer to Figure 7 and Figure 6 The folding piece 30 further comprises a plurality of first connecting strips 32. When the folding assembly 100 is in the unfolded state, the direction of the first support piece 10 towards the second support piece 20 is defined as the first direction a, and the plurality of first connecting strips 32 are sequentially arranged along the first direction a, and the length direction L1 of the first connecting strip 32 is perpendicular to the first direction a. The elastic body 31 is connected to at least one first connecting strip 32; that is, the elastic body 31 can be connected to all the first connecting strips 32, or can be connected to only one or more first connecting strips 32, and is not connected to the remaining one or more first connecting strips 32. The elastic modulus of the elastic body 31 is less than the elastic modulus of the first connecting strip 32, that is, the stiffness of the elastic body 31 is less than the stiffness of the first connecting strip 32.

[0137] The first connecting strip 32 has a long strip structure, and its length is much greater than its width and height. The first connecting strip 32 can be a rectangular strip with regular shape or a long strip structure with irregular shape. When the folding assembly 100 is in the unfolded state, the thickness direction H1 of the first connecting strip 32 is substantially perpendicular to the first direction a, that is, the thickness direction H1 of the first supporting member 10 and the thickness direction H1 of the second supporting member 20; in the terminal device 100, the thickness direction H1 of the first supporting member 10 is also the thickness direction of the display screen 500; the width direction S1 of the first connecting strip 32 is substantially parallel to the first direction a. The length direction L1, the thickness direction H1 and the width direction S1 of the first connecting strip 32 are perpendicular to each other. It can be understood that the “arranged in sequence” is not limited to uniform arrangement, and each first connecting strip 32 can be uniformly arranged along the first direction a or non-uniformly arranged.

[0138] During the process of rotating the folding assembly 100 from the unfolded state to the folded state, the folding member 30 is gradually bent, and each first connecting strip 32 can be gradually gathered. During the process of rotating the folding assembly 100 from the folded state to the unfolded state, the folding member 30 is gradually flattened, and each first connecting strip 32 can be gradually unfolded.

[0139] In this way, the arrangement of the plurality of first connecting strips 32 not only facilitates the bending deformation of the folding member 30, but also can improve the rigidity of the whole formed by the combination of the first connecting strips 32 and the elastic body 31 due to the fact that the elastic modulus of the first connecting strips 32 is greater than the elastic modulus of the elastic body 31, thereby improving the supporting and protecting effects on the foldable part 510 and facilitating the stability of the foldable part 510 in the bent or flat state, that is, facilitating the foldable part 510 to better maintain the bent or flat state.

[0140] Optionally, in some embodiments, referring to Figure 7 and Figure 6 , a first space is formed between the adjacent two first connecting strips 32, the elastic body 31 includes a first filling part 3111, and the first filling part 3111 is arranged in at least one first space, that is, the first filling part 3111 can be filled in all the first spaces or can be filled in only one or more first spaces, and the remaining one or more first spaces are not filled. The elastic body 31 includes a second filling part 3112, and the second filling part 3112 is arranged between the first supporting member 10 and the first connecting strip 32. The elastic body 31 includes a third filling part 3113, and the third filling part 3113 is arranged between the second supporting member 20 and the first connecting strip 32.

[0141] It can be understood that the first filling part 3111, the second filling part 3112 and the third filling part 3113 are all parts of the elastic body 31 and can all elastically deform.

[0142] In this way, the filling of the first filling part 3111, the second filling part 3112 and the third filling part 3113 can not only improve the structural reliability of the combination of the elastic body 31, the first connecting strip 32, the first support 10 and the second support 20, but also limit and buffer the relative movement between the two adjacent first connecting strips 32, the relative movement between the first connecting strip 32 and the first support 10, and the relative movement between the first connecting strip 32 and the second support 20, effectively reducing the possibility of instability of the foldable part 510 caused by the relative movement or dislocation between the two adjacent first connecting strips 32, the first connecting strip 32 and the first support 10, and the first connecting strip 32 and the second support 20, so as to improve the stability of the foldable part 510 in the bent form, and at the same time, the elastic body 31 can be distributed relatively widely, which is conducive to improving the effect of buffering external force.

[0143] Optionally, referring to Figure 7 , Figure 8 a perspective structural schematic view of the folding assembly 100 in the unfolded state is shown, and the first filling part 3111 can completely fill the first space, which is conducive to improving the effect of limiting and buffering. Of course, the first filling part 3111 can also only fill part of the first space and leave another part unfilled, for example Figure 8 as shown.

[0144] Similarly, the second filling part 3112 can completely fill the space between the first support 10 and the first connecting strip 32, for example Figure 6 as shown; or only fill part of the space between the first support 10 and the first connecting strip 32 and leave another part unfilled, for example Figure 8 as shown.

[0145] Similarly, the third filling part 3113 can completely fill the space between the second support 20 and the first connecting strip 32, for example Figure 6 as shown; or only fill part of the space between the second support 20 and the first connecting strip 32 and leave another part unfilled, for example Figure 8 as shown.

[0146] It should be noted that in other embodiments, at least one of the first filling part 3111, the second filling part 3112 and the third filling part 3113 can also not be provided. Figure 6 That is, a structural schematic view of the folding assembly 100 in the unfolded state is shown, in which none of the first filling part 3111, the second filling part 3112 and the third filling part 3113 is provided.

[0147] Optionally, in some embodiments, referring to Figure 9 andFigure 6 The elastic body 31 comprises a base 312 located at one side of the first connecting strip 32 along the thickness direction H1. In the terminal device 1000, the base 312 can be located at the side of the first connecting strip 32 facing the hinge mechanism 200, or at the side of the first connecting strip 32 facing the folding screen 500. It can be understood that the base 312 is part of the elastic body 31, and the elastic modulus thereof is also less than that of the first connecting strip 32, and can be elastically deformed, thereby playing a role in buffering external force.

[0148] Optionally, referring to Figure 9 and Figure 6 , the first filling part 3111, the second filling part 3112 and the third filling part 3113 can be connected to the base 312, so as to facilitate the connection of the first filling part 3111, the second filling part 3112 and the third filling part 3113 into an integrated whole through the base 312, reduce the possibility of falling off of the first filling part 3111, the second filling part 3112 and the third filling part 3113, improve the overall reliability of the elastic body 31, and improve the firmness of the connection between the elastic body 31 and the first connecting strip 32. At the same time, the first filling part 3111, the second filling part 3112, the third filling part 3113 and the base 312 can all be elastically deformed, thereby facilitating the improvement of the effect of buffering external force.

[0149] Of course, in other embodiments, at least one of the first filling part 3111, the second filling part 3112 and the third filling part 3113 can also not be connected to the base 312.

[0150] Optionally, referring to Figure 7 and Figure 6 , the base 312 can have a layered structure or a sheet structure, so as to have a larger area and be more widely distributed, thereby facilitating the improvement of the effect of buffering external force of the elastic body 31.

[0151] Of course, in other embodiments, the base 312 can also comprise a plurality of spaced sub-bases, which can have a sheet structure, a plate structure, a strip structure, a rod structure, etc., but are not limited thereto.

[0152] Optionally, referring to Figure 7 and Figure 6 , when the folding assembly 100 is in the unfolded state, the surface of the base 312 facing away from the first connecting strip 32 can be substantially flush with the lower surfaces of the first support 10 and the second support 20, and is not easy to interfere with other components (such as the hinge mechanism 200) of the terminal device 1000.

[0153] Of course, in some other embodiments, the surface of the base 312 facing away from the first connecting strips 32 can also not be flush with the lower surfaces of the first support 10 and the second support 20 when the folding assembly 100 is in the unfolded state, i.e., the surface of the base 312 facing away from the first connecting strips 32 can be higher or lower than the lower surfaces of the first support 10 and the second support 20.

[0154] It should be noted that in some other embodiments, the elastic body 31 can not be provided with the base 312, but at least one of the first filling portion 3111, the second filling portion 3112, and the third filling portion 3113. Figure 9 That is, the structural schematic diagram of the folding assembly 100 in the unfolded state is exemplarily shown without the base 312.

[0155] Optionally, in some embodiments, referring to Figure 10 , Figure 11 The folding assembly 100 in the unfolded state provided by some other embodiments of the present application is shown in the perspective structural schematic diagram. The folding piece 30 further comprises a plurality of second connecting strips 33. When the folding assembly 100 is in the unfolded state, the plurality of second connecting strips 33 are sequentially arranged along the first direction a, and the length direction of the second connecting strips 33 is perpendicular to the first direction a. Each first connecting strip 32 forms a first connecting strip group 320, and each second connecting strip 33 forms a second connecting strip group 330. When the folding assembly 100 is in the unfolded state, the first connecting strip group 320 and the second connecting strip group 330 are spaced apart along the thickness direction H1 of the first support 10. The elastic body 31 is connected to at least one second connecting strip 33; that is, the elastic body 31 can be connected to all the second connecting strips 33, or can be connected to only one or more second connecting strips 33, and is not connected to the remaining one or more second connecting strips 33. The elastic modulus of the elastic body 31 is smaller than the elastic modulus of the second connecting strip 33, that is, the stiffness of the elastic body 31 is smaller than the stiffness of the second connecting strip 33.

[0156] The second connecting strip 33 is a long strip structure, and the length thereof is much greater than the width and the height thereof. The second connecting strip 33 can be a rectangular strip with regular shape, or can be a long strip structure with irregular shape. When the folding assembly 100 is in the unfolded state, the length direction of the second connecting strip 33 is substantially parallel to the length direction L1 of the first connecting strip 32, the thickness direction of the second connecting strip 33 is substantially parallel to the thickness direction of the first connecting strip 32, and the width direction of the second connecting strip 33 is substantially parallel to the width direction of the first connecting strip 32. The length direction of the second connecting strip 33, the thickness direction of the second connecting strip 33, and the width direction of the second connecting strip 33 are perpendicular to each other in pairs. It can be understood that the shape and structure of the second connecting strip 33 can be the same as or different from those of the first connecting strip 32. Each second connecting strip 33 can be uniformly arranged along the first direction a, or can not be uniformly arranged.

[0157] In the process of rotating the folding assembly 100 from the unfolded state to the folded state, the folding piece 30 is gradually bent, each first connecting strip 32 can gradually converge, and each second connecting strip 33 can also gradually converge. In the process of rotating the folding assembly 100 from the folded state to the unfolded state, the folding piece 30 is gradually flattened, each first connecting strip 32 can gradually unfold, and each second connecting strip 33 can also gradually unfold.

[0158] In this way, when the folding assembly 100 is in the unfolded state, the first connecting strip group 320 and the second connecting strip group 330 are spaced apart along the thickness direction H1 of the first support 10, that is, two rows of spaced-apart connecting strip groups are arranged, and because the elastic modulus of the second connecting strip 33 is greater than the elastic modulus of the elastic body 31, the stiffness and structural reliability of the folding piece 30 can be further improved, not only the stability of the foldable part 510 in the bent or flat state can be improved, but also the protection effect of the folding piece 30 on the foldable part 510 can be improved, and the possibility of failure caused by the collision between the foldable part 510 and the rotating shaft mechanism 200 can be reduced.

[0159] Alternatively, referring to Figure 11 , the second connecting strip 33 is arranged opposite to the first connecting strip 32. When the folding assembly 100 is in the unfolded state, the second connecting strip 33 is arranged opposite to the first connecting strip 32 along the thickness direction H1 of the first support 10.

[0160] In this way, the second connecting strip 33 and the first connecting strip 32 are conveniently formed or arranged, and the space formed between adjacent two second connecting strips 33 is arranged opposite to the space formed between adjacent two first connecting strips 32, which is beneficial to the bending of the folding piece 30.

[0161] Of course, the second connecting strip 33 and the first connecting strip 32 are not limited to being arranged opposite to each other along the thickness direction H1 of the first support 10. In other embodiments, referring to Figure 11 , Figure 12 A perspective structural schematic view of the folding assembly 100 in the unfolded state provided by another embodiment of the present application is shown. When the folding assembly 100 is in the unfolded state, in the projection along the thickness direction H1 of the first support 10, at least one second connecting strip 33 is located between adjacent two first connecting strips 32, which can also be understood as that the second connecting strip 33 is arranged opposite to the first connecting strip 32. In this way, the overall structural reliability of the folding piece 30 can be improved, and the support effect and protection effect of the folding piece 30 on the foldable part 510 can be improved.

[0162] Alternatively, referring to Figure 12 and Figure 11 , the elastic body 31 further includes a base 312 located between the first connecting strip group 320 and the second connecting strip group 330.

[0163] In this way, the first connecting strip group 320 and the second connecting strip group 330 are spaced apart by the base 312, and when the folding screen 500 and the rotating shaft mechanism 200 collide with each other, the first connecting strip group 320 and the second connecting strip group 330 can both transmit force to the base 312 to be buffered by the base 312, so as to avoid direct collision between the first connecting strip group 320 and the second connecting strip group 330, and improve the effect of buffering external force by the folding piece 30. In addition, the base 312 can be connected to the first connecting strip group 320 and the second connecting strip group 330 at the same time, which is beneficial to improving the structural reliability of the folding piece 30.

[0164] Optionally, referring to Figure 12 and Figure 11 , the base 312 can be connected to each first connecting strip 32 and each second connecting strip 33, which is beneficial to improving the effect of buffering external force by the elastic body 31. Of course, the base 312 can also be not connected to at least one first connecting strip 32 and / or at least one second connecting strip 33.

[0165] Optionally, referring to Figure 12 and Figure 11 , a second space is formed between two adjacent second connecting strips 33, the elastic body 31 further comprises a fourth filling part 3131, the fourth filling part 3131 is connected to the base 312 and is arranged in at least one second space. The elastic body 31 further comprises a fifth filling part 3132, the fifth filling part 3132 is connected to the base 312 and is arranged between the first support 10 and the second connecting strip 33. The elastic body 31 further comprises a sixth filling part 3133, the sixth filling part 3133 is connected to the base 312 and is arranged between the second support 20 and the second connecting strip 33.

[0166] It can be understood that the fourth filling part 3131, the fifth filling part 3132 and the sixth filling part 3133 are all part of the elastic body 31 and can all elastically deform.

[0167] In this way, the filling of the fourth filling part 3131, the fifth filling part 3132 and the sixth filling part 3133 can not only improve the structural reliability of the combination of the elastic body 31, the second connecting strip 33, the first support 10 and the second support 20, but also limit and buffer the relative movement between the two adjacent second connecting strips 33, the relative movement between the second connecting strip 33 and the first support 10, and the relative movement between the second connecting strip 33 and the second support 20, effectively reducing the possibility of relative movement between the two adjacent second connecting strips 33, between the first connecting strip 32 and the first support 10, and between the first connecting strip 32 and the second support 20, so as to improve the stability of the foldable part 510 in the bent state, and at the same time, the elastic body 31 can be distributed relatively widely, which is conducive to improving the effect of buffering external force.

[0168] In addition, the fourth filling part 3131, the fifth filling part 3132 and the sixth filling part 3133 are connected into one body by the base 312, which can reduce the possibility of falling off of the fourth filling part 3131, the fifth filling part 3132 and the sixth filling part 3133, improve the overall reliability of the elastic body 31, and the firmness of the connection between the elastic body 31 and the second connecting strip 33; and in cooperation with the fourth filling part 3131, the fifth filling part 3132 and the sixth filling part 3133, the elastic body 31 has a more excellent effect of buffering external force.

[0169] Alternatively, the fourth filling part 3131 can completely fill the second space, which is conducive to improving the effect of limiting and buffering; of course, the fourth filling part 3131 can also only fill part of the second space, and leave another part unfilled. Similarly, the fifth filling part 3132 can completely fill the space between the first support 10 and the second connecting strip 33, or can only fill part of the space between the first support 10 and the second connecting strip 33, and leave another part of the space unfilled. The sixth filling part 3133 can completely fill the space between the second support 20 and the second connecting strip 33, or can only fill part of the space between the second support 20 and the second connecting strip 33, and leave another part of the space unfilled.

[0170] It should be noted that in other embodiments, at least one of the fourth filling part 3131, the fifth filling part 3132 and the sixth filling part 3133 can also not be provided. Figure 12 That is, the fourth filling part 3131, the fifth filling part 3132 and the sixth filling part 3133 are not provided.

[0171] Alternatively, in some embodiments, please refer to Figure 13When the folding assembly 100 is in the unfolded state, each first connecting strip 32 is uniformly arranged along the first direction a, that is, the distance between any two adjacent first connecting strips 32 is substantially the same, and each second connecting strip 33 is uniformly arranged along the first direction a, that is, the distance between any two adjacent second connecting strips 33 is substantially the same.

[0172] In this way, the overall structural strength of the folding piece 30 is relatively uniform, which can improve the supporting effect and protection effect on the foldable part 510, and is beneficial to improve the stability of the foldable part 510 in the bent shape and the flat shape.

[0173] Optionally, in other embodiments, please refer to Figure 11 , Figure 14 A perspective structural schematic diagram of the folding assembly 100 in the unfolded state provided by another embodiment of the present application is shown. The folding piece 30 includes a first region 301, a second region 302, and a third region 303. The first region 301 is located on one side of the first support 10, the second region 302 is located on one side of the second support 20, and the third region 303 is located between the first region 301 and the second region 302. The first region 301 and the second region 302 are each provided with at least one first connecting strip 32, and the third region 303 is not provided with a first connecting strip 32. The first region 301 and the second region 302 are each provided with at least one second connecting strip 33, and the third region 303 is not provided with a second connecting strip 33.

[0174] The side of the foldable part 510 close to the first support 10 is defined as a first bending part 5101, and the other side of the foldable part 510 close to the second support 20 is defined as a second bending part 5102, for example Figure 14 The first bending part 5101 and the second bending part 5102 are transition parts between the foldable part 510 and other parts of the folding screen 500. When the foldable part 510 is subjected to external force, the first bending part 5101 and the second bending part 5102 are usually the most vulnerable parts, especially when the folding screen 500 is in the folded state, the foldable part 510 is in the bent shape, and when subjected to external force, the first bending part 5101 and the second bending part 5102 are usually the stress concentration parts and are the most vulnerable, especially when the bent shape of the foldable part 510 is in the water drop shape. The position of the first region 301 substantially corresponds to the position of the first bending part 5101, and the position of the second region 302 substantially corresponds to the position of the second bending part 5102.

[0175] In this way, by arranging the at least one first connecting strip 32 and the at least one second connecting strip 33 in the first region 301 and the second region 302, and not arranging the first connecting strip 32 and the second connecting strip 33 in the third region 303, the strength of the portions of the folding piece 30 close to the first support 10 and the second support 20 is greater than the strength of the middle portion, effective support and protection can be provided to the two side portions of the foldable portion 510, the possibility of damage to the portion of the foldable portion 510 most susceptible to damage is reduced, and the safety of the folding screen 500 is improved. In addition, because the third region 303 does not arrange the first connecting strip 32 and the second connecting strip 33, the material can be saved, and the weight is reduced.

[0176] Of course, in other embodiments, when the folding piece 30 does not arrange the second connecting strip 33, the first region 301 and the second region 302 can both arrange the at least one first connecting strip 32, and the third region 303 does not arrange the first connecting strip 32, Figure 5 That is, the folding assembly 100 without the second connecting strip 33 is exemplarily shown in the perspective structural schematic view in the unfolded state.

[0177] In some embodiments, referring to Figure 15 and Figure 6 , the first support 10 includes a first side surface 11, which faces the second support 20 when the folding assembly 100 is in the unfolded state. The first side surface 11 is provided with a first groove 1101; the elastic body 31 includes a first connecting portion 3141, which is arranged in the first groove 1101. It can be understood that the first connecting portion 3141 is part of the elastic body 31 and can also be elastically deformed.

[0178] In this way, because the elastic body 31 is connected to the first groove 1101 of the first support 10 through the first connecting portion 3141, the firmness of the connection between the elastic body 31 and the first support 10 is improved, and the reliability of the connection between the folding piece 30 and the first support 10 is further improved.

[0179] Optionally, referring to Figure 8 and Figure 6 , the first connecting portion 3141 can be connected to the base 312, which can also be regarded as that the first connecting portion 3141 is formed by the base 312 extending toward the first support 10. The first connecting portion 3141 and the base 312 can be an integrated structure formed integrally, and the structural reliability is high.

[0180] Optionally, referring to Figure 8 and Figure 6, a first gap 101 is formed between the end of the first connecting portion 3141 and the inner wall of the first groove 1101. It should be understood that the width or size of the first gap 101 can be set as required; when the width of the first gap 101 is small, it may not be obvious to the naked eye, but as long as the end of the first connecting portion 3141 is not completely attached to the inner wall of the first groove 1101, it is considered that the first gap 101 is formed between the end of the first connecting portion 3141 and the inner wall of the first groove 1101.

[0181] In this way, when the folding assembly 100 is switched between the folded state and the unfolded state, the first gap 101 can provide a relief space to accommodate the extrusion deformation amount of the first connecting portion 3141 when it deforms, reduce the possibility of the first connecting portion 3141 being separated from the first support 10 due to the extrusion deformation amount, and reduce the possibility of the elastic body 31 being arched due to the extrusion deformation amount, thereby improving the stability of the connection between the elastic body 31 and the first support 10. At the same time, since the first connecting portion 3141 and the first support 10 are made of different materials, when affected by the external environment (for example, affected by temperature), the expansion amount of the first connecting portion 3141 is different from that of the first support 10, and the first gap 101 can accommodate the expansion amount of the first connecting portion 3141, thereby reducing the possibility of the first connecting portion 3141 being separated from the first support 10 due to the expansion amount, and reducing the possibility of the elastic body 31 being arched due to the expansion amount.

[0182] Optionally, in some embodiments, referring to Figure 8 and Figure 6 , the second support 20 includes a second side surface 21, which faces the first support 10 when the folding assembly 100 is in the unfolded state, i.e., the second side surface 21 is arranged opposite to the first side surface 11. The second side surface 21 is provided with a second groove 2101, and the elastic body 31 further includes a second connecting portion 3142 arranged in the second groove 2101. It can be understood that the second connecting portion 3142 is part of the elastic body 31 and can also be elastically deformed.

[0183] In this way, since the elastic body 31 is connected to the second groove 2101 of the second support 20 through the second connecting portion 3142, the firmness of the connection between the elastic body 31 and the second support 20 can be improved, thereby improving the reliability of the connection between the folding piece 30 and the second support 20.

[0184] Optionally, referring to Figure 8 and Figure 6The second connecting portion 3142 can be connected to the base 312, and can be considered as being formed by the base 312 extending towards the second support 20. The second connecting portion 3142 and the base 312 can be integrally formed, and have high structural reliability.

[0185] Optionally, referring to Figure 8 and Figure 6 , a second gap 102 is formed between the end of the second connecting portion 3142 and the inner wall of the second groove 2101. It should be understood that the width or size of the second gap 102 can be set as required; when the width of the second gap 102 is small, it can not be obvious to the naked eye, but as long as the end of the second connecting portion 3142 is not completely attached to the inner wall of the second groove 2101, it is considered that the second gap 102 is formed between the end of the second connecting portion 3142 and the inner wall of the second groove 2101.

[0186] In this way, when the folding assembly 100 is switched between the folded state and the unfolded state, not only can the first gap 101 provide a space for accommodating the extrusion deformation amount of the first connecting portion 3141 when the first connecting portion 3141 is deformed, and the expansion amount of the first connecting portion 3141 affected by the external environment, but also the second groove 2101 can provide a space for accommodating the extrusion deformation amount of the second connecting portion 3142 when the second connecting portion 3142 is deformed, and the expansion amount of the second connecting portion 3142 affected by the external environment, thereby reducing the possibility of the second connecting portion 3142 being separated from the second support 20, and further reducing the possibility of the elastic body 31 being arched due to the extrusion deformation amount or the expansion amount, thereby improving the stability of the folding piece 30.

[0187] The matching relationship or connection mode between the elastic body 31 and the first connecting strip 32 has various modes, which will be exemplarily introduced below.

[0188] Optionally, in some embodiments, referring to Figure 8 , the elastic body 31 is a spacer pad; that is, the elastic body 31 is a pad structure arranged separately from the first connecting strip 32, that is, the elastic body 31 is connected to the first connecting strip 32 after being formed.

[0189] Optionally, the elastic body 31 as a spacer pad can be directly arranged on the first connecting strip 32, or can be connected to the first connecting strip 32 through adhesive or the like.

[0190] Optionally, in some other embodiments, referring to Figure 6The elastic body 31 is a coating layer coated on the first connecting strip 32. That is, the unshaped coating (in a fluid state, for example, a glue of various materials) is coated on the first connecting strip 32, and after solidification, the elastic body 31 in the form of a coating layer is formed. In this way, the elastic body 31 is conveniently formed and molded, and does not need to be additionally bonded by using a glue.

[0191] Alternatively, in other embodiments, referring to Figure 8 and Figure 11 , the elastic body 31 and the first connecting strip 32 are in an injection-molded integrated structure. That is, the elastic body 31 is formed on the first connecting strip 32 by injection molding, so that the elastic body 31 and the first connecting strip 32 are in full contact, and the reliability of the connection between the elastic body 31 and the first connecting strip 32 is improved. For example, the first connecting strip 32 can be arranged in a mold, and then a material in a fluid state for forming the elastic body 31 is injected into the mold, and after solidification and molding, the elastic body 31 is formed and is in close contact with the first connecting strip 32.

[0192] It can be understood that the above-described cooperation relationship or connection mode between the elastic body 31 and the first connecting strip 32 can be adopted for the cooperation relationship or connection mode between the elastic body 31 and the second connecting strip 33. For example, when the elastic body 31 is a spacer, the elastic body 31 can be bonded or directly arranged on the second connecting strip 33, when the elastic body 31 is a coating layer, the elastic body 31 can be coated on the second connecting strip 33, and the elastic body 31 and the second connecting strip 33 can also be in an injection-molded integrated structure.

[0193] Referring to Figure 12 , Figure 16 to Figure 19 a perspective structural schematic view of the folding assembly 100 in an unfolded state according to another embodiment of the present application is shown, Figure 16 a structural schematic view of the folding assembly 100 shown in Figure 17 and the folding screen 500 cooperating and being in a folded state is shown; Figure 16 a perspective structural schematic view of the folding assembly 100 in an unfolded state according to another embodiment of the present application is shown, Figure 18 a structural schematic view of the folding assembly 100 shown in Figure 19 and the folding screen 500 cooperating and being in a folded state is shown.

[0194] In some embodiments, the first support 10 includes a first face 12 and a second face 13, and the first face 12 and the second face 13 are oppositely arranged along a thickness direction H1 of the first support 10. The elastic body 31 includes a first protruding portion 3151, and the first protruding portion 3151 protrudes from the first face 12, that is, the first protruding portion 3151 extends to the outside of the first face 12.

[0195] It can be understood that in the terminal device 1000, when the first surface 12 faces the folding screen 500, the first protruding part 3151 protrudes towards the folding screen 500, and the second surface 13 faces away from the folding screen 500, for example as shown in Figure 18 and Figure 16 When the second surface 13 faces the folding screen 500, the first surface 12 faces away from the folding screen 500, and the first protruding part 3151 protrudes away from the folding screen 500, for example as shown in Figure 17 and Figure 18 The first protruding part 3151 is part of the elastic body 31 and can elastically deform.

[0196] It can be understood that the first protruding part 3151 can be various regular or irregular protruding structures, such as strip-shaped structures, columnar structures, bulge structures, conical structures, spherical structures, etc., but is not limited thereto.

[0197] In this way, when the folding screen 500 is subjected to an external force, for example, when the folding screen 500 collides with the rotating shaft mechanism 200, the first protruding part 3151 protrudes from the first surface 12 and can first deform under stress, i.e., the elastic body 31 can first bear the stress to buffer the external force, which is beneficial to improve the effect of buffering the external force, and the first protruding part 3151 can function as a spring.

[0198] Alternatively, referring to Figure 19 and Figure 16 The first protruding part 3151 can be connected to the base 312, i.e., protrudes from the surface of the base 312, and the base 312 can provide support for the first protruding part 3151, and the first protruding part 3151 can also transmit the force to the base 312 to further buffer the external force through the base 312.

[0199] Alternatively, referring to Figure 18 The first protruding part 3151 can be arranged on at least one of the first filling part 3111, the second filling part 3112, and the third filling part 3113, and the first protruding part 3151 can transmit the stress to at least one of the first filling part 3111, the second filling part 3112, and the third filling part 3113 to further buffer the external force through at least one of the first filling part 3111, the second filling part 3112, and the third filling part 3113. Alternatively, referring to Figure 16 The first protruding part 3151 is arranged on at least one of the fourth filling part 3131, the fifth filling part 3132, and the sixth filling part 3133, and the first protruding part 3151 can transmit the stress to at least one of the fourth filling part 3131, the fifth filling part 3132, and the sixth filling part 3133 to further buffer the external force through at least one of the fourth filling part 3131, the fifth filling part 3132, and the sixth filling part 3133.

[0200] Optionally, the first protruding part 3151 can protrude from the outer surface of the first connecting strip 32 (for example Figure 18 as shown), or protrude from the outer surface of the second connecting strip 33 (for example Figure 16 as shown), which is more conducive to the first protruding part 3151 being stressed first and improving the effect of buffering external force.

[0201] Optionally, when the first protruding part 3151 protrudes towards the folding screen 500, the first protruding part 3151 and the foldable part 510 of the folding screen 500 can be bonded by adhesive to improve the support and protection effect on the foldable part 510. Of course, in other embodiments, the first protruding part 3151 and the foldable part 510 of the folding screen 500 can also not be bonded, for example, they can be directly in contact.

[0202] Optionally, in some embodiments, referring to Figure 18 and Figure 16 , the number of first protruding parts 3151 is multiple, and a first gap 3001 is formed between adjacent two first protruding parts 3151.

[0203] It can be understood that when the number of first protruding parts 3151 is two, one first gap 3001 can be formed, and when the number of first protruding parts 3151 is three or more, at least two first gaps 3001 can be formed. The first protruding parts 3151 can be uniformly arranged, and the width or size of the first gap 3001 is substantially the same; the first protruding parts 3151 can also be non-uniformly arranged, and the width or size of the at least two first gaps 3001 is different.

[0204] In this way, when the folding screen 500 is subjected to external force, for example, when the folding screen 500 collides with the shaft mechanism 200, the first protruding part 3151 is stressed first and can be deformed to resist the external force, and the first gap 3001 can accommodate the deformation amount of the first protruding part 3151, so that the first protruding part 3151 can fully deform to resist the external force, which can effectively improve the effect of buffering external force; and compared with a plate-shaped structure with a larger area, the first protruding part 3151 arranged in multiple intervals is more likely to deform under stress, which can improve the buffering effect.

[0205] Optionally, referring to Figure 18 and Figure 16 , the first protruding part 3151 is a protruding strip structure; when the folding assembly 100 is in the unfolded state, the direction of the first support 10 towards the second support 20 is the first direction a, and the plurality of first protruding parts 3151 are arranged in sequence along the first direction a, and the length direction of the first protruding part 3151 is perpendicular to the first direction a.

[0206] The first protruding part 3151 is in a strip shape, and the length thereof is greater than the width and thickness thereof. The first protruding part 3151 can be a rectangular strip with regular shape, or a strip shape with irregular shape. When the folding assembly 100 is in the unfolded state, the thickness direction of the first protruding part 3151 is substantially perpendicular to the first direction a, the width direction of the first protruding part 3151 is substantially parallel to the first direction a, and the length direction of the first protruding part 3151, the thickness direction of the first protruding part 3151 and the width direction of the first protruding part 3151 are perpendicular to each other. When the folding piece 30 comprises the first connecting strip 32, the length direction of the first protruding part 3151 is substantially parallel to the length direction L1 of the first connecting strip 32, the thickness direction of the first protruding part 3151 is substantially parallel to the thickness direction H1 of the first connecting strip 32, and the width direction of the first protruding part 3151 is substantially parallel to the width direction S1 of the first connecting strip 32. It can be understood that the first protruding parts 3151 can be arranged uniformly along the first direction a, or can be arranged non-uniformly.

[0207] In this way, the plurality of first protruding parts 3151 arranged along the first direction a in sequence are in a strip shape, which can increase the force receiving area in contact with the folding screen 500 or the rotating shaft mechanism 200, and can better support the folding screen 500 or be in contact with the rotating shaft mechanism 200 to buffer external force. Compared with a plate shape, the strip shape is beneficial to deformation to buffer external force. Moreover, the strip shape is convenient for processing and forming.

[0208] For example, referring to Figure 18 and Figure 16 In the terminal device 1000, the first protruding part 3151 protrudes towards the folding screen 500, and in the process of rotating the folding assembly 100 from the unfolded state to the folded state, the folding piece 30 is gradually bent, and the first protruding parts 3151 can gradually converge. In the process of rotating the folding assembly 100 from the folded state to the unfolded state, the folding piece 30 is gradually flattened, and the first protruding parts 3151 can gradually expand.

[0209] Optionally, in some embodiments, referring to Figure 17 and Figure 16 In the unfolded state of the folding assembly 100, the first protruding parts 3151 are arranged uniformly along the first direction a, that is, the distance between any two adjacent first protruding parts 3151 is substantially the same.

[0210] In this way, the first protruding parts 3151 can uniformly support the foldable part 510 or the rotating shaft mechanism 200, and can improve the support effect on the foldable part 510 and the effect of buffering external force, thereby improving the stability of the foldable part 510 in the bent state and the flattened state.

[0211] Optionally, in another embodiment, referring toFigure 18 and Figure 20 , Figure 21 Fig. 1 shows a perspective view of a folding assembly 100 in an unfolded state according to some embodiments of the present application, Figure 20 Fig. 2 shows a perspective view of the folding assembly 100 in a folded state according to some embodiments of the present application, Figure 21 Fig. 3 shows a perspective view of the folding assembly 100 cooperating with a folding screen 500 and in a folded state according to some embodiments of the present application. The folding member 30 comprises a first region 301, a second region 302 and a third region 303. The first region 301 is located at one side of the first support member 10, the second region 302 is located at one side of the second support member 20, and the third region 303 is located between the first region 301 and the second region 302. The first region 301 and the second region 302 are each provided with at least one first protruding part 3151, and the third region 303 is not provided with the first protruding part 3151.

[0212] In this way, when the foldable part 510 is in the folded state, the part of the folding member 30 close to the first support member 10 and the part close to the second support member 20 can both be buffered by the first protruding part 3151, that is, both sides of the foldable part 510 (the first bending part 5101 and the second bending part 5102) can be protected by the first protruding part 3151, which can reduce the possibility of damage to the part of the foldable part 510 most susceptible to damage and improve the safety of the folding screen 500. It is especially suitable for the case where the bending shape of the foldable part 510 is in a water drop shape, because when the bending shape of the foldable part 510 is in a water drop shape, the outside of the first bending part 5101 and the outside of the second bending part 5102 can both form a recessed space 501, which is conducive to avoiding the first protruding part 3151 and improving the stability of the foldable part 510 in the bending shape.

[0213] At the same time, because the third region 303 is not provided with the first protruding part 3151, an avoidance space can be formed. When the first face 12 faces the folding screen 500, the avoidance space can avoid the redundant amount of the foldable part 510 in the bending shape, which is conducive to improving the stability of the foldable part 510 in the bending shape and making the surface of the foldable part 510 in the bending shape smoother (not easy to wrinkle or bulge due to the resistance of the folding member 30 when in the bending shape). When the first face 12 faces the hinge mechanism 200, the avoidance space can avoid the hinge mechanism 200. Moreover, because the third region 303 is not provided with the first protruding part 3151, it is conducive to saving materials and reducing weight.

[0214] Optionally, please refer to Figure 20In the unfolded state of the folding assembly 100, the width of the third region 303 is greater than the width of the first region 301 and the width of the second region 302 in the direction of the first support 10 towards the second support 20 (i.e. the first direction a), which is conducive to appropriately increasing the width of the third region 303 to form a larger space for avoiding, so as to better avoid the redundant amount of the foldable part 510 in the bent state or the pivot mechanism 200.

[0215] Of course, in other embodiments, in the unfolded state of the folding assembly 100, the width of the third region 303 can also be equal to or less than the width of the first region 301 and the width of the second region 302 in the direction of the first support 10 towards the second support 20.

[0216] Optionally, in some embodiments, referring to Figure 20 , Figure 22 A schematic diagram of the folding assembly 100 in the unfolded state according to some embodiments of the present application is shown. The folding assembly 100 further comprises a support film 40 located on the side of the first protruding part 3151 of the folding piece 30. The support film 40 is provided with a groove 401, and the first protruding part 3151 extends into the groove 401.

[0217] It can be understood that when the number of the first protruding part 3151 is multiple, the number of the groove 401 can be the same as the number of the first protruding part 3151, so that the first protruding part 3151 and the groove 401 are arranged one by one. The support film 40 is a thin film structure, which can be a hard material support film, for example, can include metal materials (such as stainless steel, etc.), alloys, etc., but is not limited thereto; or a soft material support film, for example, can include rubber, silicone, soft PVC, TPE, TPU, TPR, TPV, etc., but is not limited thereto.

[0218] In this way, the support film 40 can support and protect the folding screen 500, improve the reliability of the folding screen 500 when subjected to external force, and further reduce the possibility of damage to the foldable part 510 when subjected to external force. At the same time, the groove 401 provided on the support film 40 can limit the first protruding part 3151 extending into it, so as to reduce the possibility of the first protruding part 3151 deviating, limit the relative movement between the first protruding part 3151 and the support film 40, and improve the stability of the folding piece 30 in the bending or flattening process and when subjected to external force, as well as the stability of the cooperation between the folding piece 30 and the support film 40, thereby improving the support and protection effect on the foldable part 510, and facilitating the foldable part 510 to more stably maintain the bent state or the flat state.

[0219] Exemplarily, referring to Figure 22 ,Figure 23 This indicates the adoption Figure 23 This is a partial structural diagram of the terminal device 1000 of the folding assembly 100 shown. In the terminal device 1000, the first surface 12 faces the pivot mechanism 200, the first protrusion 3151 protrudes towards the pivot mechanism 200, and the support film 40 is located between the folding member 30 and the pivot mechanism 200. The support film 40 can be fixed to at least one of the pivot mechanism 200, the first housing 300, and the second housing 400. There can be gaps between the support film 40 and the first support member 10, and between the support film 40 and the second support member 20. When the terminal device 1000 switches between the folded state and the unfolded state, the groove 401 on the support film 40 can limit the first protrusion 3151, thereby limiting the large relative movement between the folding member 30 and the support film 40, and between the folding member 30 and the folding screen 500, which helps the foldable part 510 to maintain a more stable bent or flat shape.

[0220] For example, in the terminal device 1000, the first surface 12 faces the pivot mechanism 200, the first protrusion 3151 protrudes towards the pivot mechanism 200, and the support film 40 is located between the folding member 30 and the pivot mechanism 200. The support film 40 can be fixed to at least one of the first support member 10 and the second support member 20, and there can be a gap between the support film 40 and the pivot mechanism 200. When the terminal device 1000 switches between the folded state and the unfolded state, the groove 401 opened on the support film 40 can limit the first protrusion 3151, thereby limiting the large relative movement between the folding member 30 and the support film 40, improving the stability of the fit between the folding member 30 and the support film 40, and thus helping the foldable part 510 to maintain a more stable bent or flat shape.

[0221] For example, in the terminal device 1000, the first surface 12 faces the folding screen 500, the first protrusion 3151 protrudes towards the folding screen 500, and the support film 40 is located between the folding member 30 and the folding screen 500. The support film 40 can be fixed to at least one of the first support member 10 and the second support member 20, or fixed to the folding screen 500. When the terminal device 1000 switches between the folded state and the unfolded state, the groove 401 opened on the support film 40 can limit the first protrusion 3151, thereby limiting the large relative movement between the folding member 30 and the support film 40, and between the folding member 30 and the folding screen 500, which helps the foldable part 510 to maintain a more stable bent or flat shape.

[0222] It should be noted that in some other embodiments, the support membrane 40 may not be provided.

[0223] Optionally, in some embodiments, please refer to Figure 22 ,Figure 22 and Figure 24 , Figure 25 Fig. 2 shows a perspective view of the folding assembly 100 in an unfolded state according to another embodiment of the present application, Figure 24 Fig. 3 shows a perspective view of the folding assembly 100 in a folded state according to another embodiment of the present application, Figure 25 Fig. 4 shows a perspective view of the folding assembly 100 cooperating with the folding screen 500 and in a folded state according to another embodiment of the present application. The elastic body 31 further comprises a second protruding portion 3152 protruding from the second surface 13, i.e. the second protruding portion 3152 extends to the outside of the second surface 13.

[0224] It can be understood that when the first surface 12 faces the folding screen 500, the first protruding portion 3151 protrudes towards the folding screen 500, and the second surface 13 faces away from the folding screen 500, and the second protruding portion 3152 protrudes away from the folding screen 500, for example as shown in Fig. 4. Figure 24 It can be understood that when the first surface 12 faces the folding screen 500, the first protruding portion 3151 protrudes towards the folding screen 500, and the second surface 13 faces away from the folding screen 500, and the second protruding portion 3152 protrudes away from the folding screen 500, for example as shown in Fig. 4.

[0225] It can be understood that the second protruding portion 3152 can be various regular or irregular protruding structures, such as strip-shaped structures, columnar structures, bulge structures, conical structures, spherical structures, etc., but is not limited thereto. The shape of the second protruding portion 3152 can be the same as or different from the shape of the first protruding portion 3151.

[0226] In this way, when the folding screen 500 is subjected to an external force, for example, when the folding screen 500 collides with the rotating shaft mechanism 200, since the second protruding portion 3152 protrudes from the second surface 13, both the second protruding portion 3152 and the first protruding portion 3151 can be first subjected to the force, i.e. the elastic body 31 can be first subjected to the force to buffer the external force, which is beneficial to improve the effect of buffering the external force, and the second protruding portion 3152 functions as a spring. Since the protruding directions of the first protruding portion 3151 and the second protruding portion 3152 are opposite, the elastic body 31 can buffer the external force on both the side facing the folding screen 500 and the side facing the rotating shaft mechanism 200, which can further improve the effect of buffering the external force and reduce the possibility of damage to the foldable part 510 of the folding screen 500.

[0227] Optionally, please refer to Figure 25The second protruding part 3152 can be connected to the base 312, that is, protrude from the surface of the base 312, and the base 312 can provide support for the second protruding part 3152. When the second protruding part 3152 is subjected to force, the force can also be transmitted to the base 312 to further buffer the external force through the base 312.

[0228] Optionally, referring to Figure 24 At least one of the first filling part 3111, the second filling part 3112, and the third filling part 3113 can be provided with the second protruding part 3152. When the second protruding part 3152 is subjected to force, the force can be transmitted to at least one of the first filling part 3111, the second filling part 3112, and the third filling part 3113 to further buffer the external force through at least one of the first filling part 3111, the second filling part 3112, and the third filling part 3113. In this case, at least one of the fourth filling part 3131, the fifth filling part 3132, and the sixth filling part 3133 can be provided with the first protruding part 3151.

[0229] Of course, at least one of the fourth filling part 3131, the fifth filling part 3132, and the sixth filling part 3133 can be provided with the second protruding part 3152. When the second protruding part 3152 is subjected to force, the force can be transmitted to at least one of the fourth filling part 3131, the fifth filling part 3132, and the sixth filling part 3133 to further buffer the external force through at least one of the fourth filling part 3131, the fifth filling part 3132, and the sixth filling part 3133. In this case, at least one of the first filling part 3111, the second filling part 3112, and the third filling part 3113 can be provided with the first protruding part 3151.

[0230] Optionally, the second protruding part 3152 can protrude from the outer surface of the first connecting strip 32, and the first protruding part 3151 can protrude from the outer surface of the second connecting strip 33, for example, as shown in Figure 24 Of course, the second protruding part 3152 can protrude from the outer surface of the second connecting strip 33, and the first protruding part 3151 can protrude from the outer surface of the first connecting strip 32.

[0231] Optionally, when the second protruding part 3152 protrudes towards the foldable screen 500, the second protruding part 3152 and the foldable part 510 of the foldable screen 500 can be bonded by adhesive to improve the support and protection effect on the foldable part 510. Of course, in some other embodiments, the second protruding part 3152 and the foldable part 510 of the foldable screen 500 can also not be bonded, for example, can be directly in contact.

[0232] Optionally, referring to Figure 24The number of the second protrusions 3152 is multiple, and a second gap 3002 is formed between two adjacent second protrusions 3152.

[0233] It can be understood that when the number of the second protrusions 3152 is two, one second gap 3002 can be formed, and when the number of the second protrusions 3152 is three or more, at least two second gaps 3002 can be formed. The second protrusions 3152 can be uniformly arranged, and the widths or sizes of the second gaps 3002 are substantially the same. The second protrusions 3152 can also be non-uniformly arranged, and the widths or sizes of the at least two second gaps 3002 are different.

[0234] In this way, when the folding screen 500 is subjected to an external force, for example, when the folding screen 500 collides with the hinge mechanism 200, the second protrusions 3152 are subjected to the force and can be deformed to resist the external force, and the second gap 3002 can accommodate the deformation amount of the second protrusions 3152, so that the second protrusions 3152 can be fully deformed to resist the external force, and the elasticity of the elastic body 31 can be further improved on the basis of the first protrusions 3151. Moreover, compared with a plate-shaped structure with a large area, the second protrusions 3152 arranged at intervals are more likely to be deformed under stress, and the buffering effect can be improved.

[0235] Optionally, referring to Figure 24 The second protrusions 3152 are in a strip structure. When the folding assembly 100 is in the unfolded state, the direction of the first support 10 towards the second support 20 is the first direction a, the multiple second protrusions 3152 are arranged in sequence along the first direction a, and the length direction of the second protrusions 3152 is perpendicular to the first direction a.

[0236] The second protruding part 3152 is in a strip shape, and the length thereof is greater than the width and thickness thereof. The second protruding part 3152 can be a rectangular strip with regular shape or a strip shape with irregular shape. When the folding assembly 100 is in the unfolded state, the thickness direction of the second protruding part 3152 is substantially perpendicular to the first direction a, the width direction of the second protruding part 3152 is substantially parallel to the first direction a, and the length direction of the second protruding part 3152, the thickness direction of the second protruding part 3152 and the width direction of the second protruding part 3152 are perpendicular to each other. When the folding piece 30 comprises the first connecting strip 32, the length direction of the second protruding part 3152 is substantially parallel to the length direction L1 of the first connecting strip 32, the thickness direction of the second protruding part 3152 is substantially parallel to the thickness direction H1 of the first connecting strip 32, and the width direction of the second protruding part 3152 is substantially parallel to the width direction S1 of the first connecting strip 32. It can be understood that the second protruding parts 3152 can be arranged uniformly along the first direction a or non-uniformly. The shape and structure of the second protruding part 3152 can be the same as or different from those of the first protruding part 3151.

[0237] In this way, the plurality of second protruding parts 3152 arranged along the first direction a in sequence are in a strip structure, which can increase the force receiving area in contact with the folding screen 500 or the rotating shaft mechanism 200, better support the folding screen 500 or be in contact with the rotating shaft mechanism 200 to buffer external force, and be deformed to buffer external force, and the strip structure is convenient for processing and forming.

[0238] Optionally, referring to Figure 24 and Figure 24 , the second protruding part 3152 is arranged opposite to the first protruding part 3151. When the folding assembly 100 is in the unfolded state, the second protruding part 3152 and the first protruding part 3151 are arranged opposite along the thickness direction H1 of the first support 10.

[0239] In this way, the second protruding part 3152 and the first protruding part 3151 are convenient for processing and forming, and the space formed between the adjacent two second protruding parts 3152 and the space formed between the adjacent two first protruding parts 3151 are arranged opposite, which is beneficial for bending the folding piece 30.

[0240] Of course, the second protruding part 3152 and the first protruding part 3151 are not limited to being arranged opposite along the thickness direction H1 of the first support 10. In other embodiments, referring to Figure 25 and Figure 26 , Figure 27 a perspective structural schematic view of the folding assembly 100 in the unfolded state is shown, Figure 26 a perspective structural schematic view of the folding assembly 100 in the folded state is shown, Figure 27A structural schematic view of the folding assembly 100 in cooperation with the folding screen 500 and in the folded state.

[0241] In the unfolded state of the folding assembly 100, the projection of the second protruding portion 3152 in the direction from the first face 12 to the second face 13 is between two adjacent first protruding portions 3151, that is, the second protruding portion 3152 is arranged in a staggered manner with the first protruding portions 3151. In this way, the second protruding portion 3152 is arranged opposite the space formed between the two adjacent first protruding portions 3151, so as to buffer external force in the direction of the space, so that the overall buffering effect of the elastic body 31 is more comprehensive and uniform, which is beneficial to improve the effect of buffering external force, further reduce the risk of failure caused by damage of the foldable part 510, and improve the overall structural reliability of the folding part 30. The direction from the first face 12 to the second face 13 is the thickness direction H1 of the first support 10.

[0242] Optionally, referring to Figure 26 and Figure 28 , Figure 29 a perspective structural schematic view of the folding assembly 100 in the unfolded state is shown, Figure 28 schematically shows Figure 29 A structural schematic view of the folding assembly 100 in cooperation with the folding screen 500 and in the folded state. The first region 301 and the second region 302 are each provided with at least one second protruding portion 3152, and the third region 303 is not provided with the second protruding portion 3152.

[0243] In this way, when the foldable part 510 is in the folded state, both sides (the first bending part 5101 and the second bending part 5102) of the foldable part 510 can be protected by the second protruding portion 3152, which can reduce the possibility of damage to the most vulnerable part of the foldable part 510 and improve the safety of the folding screen 500. It is especially suitable for the case where the bending shape of the foldable part 510 is in a drop shape, because when the bending shape of the foldable part 510 is in a drop shape, the outer side of the first bending part 5101 and the outer side of the second bending part 5102 can form a concave space 501, which is beneficial to avoid the second protruding portion 3152 and improve the stability of the foldable part 510 in the bending shape.

[0244] Meanwhile, since the third area 303 is not provided with the second protruding part 3152, a space for avoiding can be formed. When the second surface 13 faces the folding screen 500, the space for avoiding can avoid the redundant amount of the foldable part 510 in the bent state, which is beneficial to improve the stability of the foldable part 510 in the bent state and make the surface of the foldable part 510 in the bent state smoother (not easy to wrinkle or bulge due to the resistance to the folding part 30 in the bent state). When the second surface 13 faces the rotating shaft mechanism 200, the space for avoiding can avoid the rotating shaft mechanism 200. Moreover, since the third area 303 is not provided with the second protruding part 3152, it is beneficial to save materials and reduce the weight.

[0245] Optionally, referring to Figure 28 and Figure 24 Figure 26 , the base 312 is connected to the first support 10 and the second support 20, which can improve the reliability of the connection between the elastic body 31 and the first support 10 and the second support 20. The first protruding part 3151 and the second protruding part 3152 are both connected to the base 312, which can improve the stability and structural reliability of the whole elastic body 31.

[0246] Optionally, the base 312, the first protruding part 3151 and the second protruding part 3152 can be an integrated structure formed integrally, which has high structural reliability. Further, the elastic body 31 can be an integrated structure formed integrally, which can further improve the overall reliability.

[0247] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application.
