Referring to fig. 1 and 2, fig. 1 shows a front view of a foldable electronic device 1 in the related art in an unfolded state, and fig. 2 shows a front view of the electronic device 1 shown in fig. 1 in a folded state.

The electronic apparatus 1 includes a folding mechanism 011, a first side plate 012, a second side plate 013, and a flexible display 02. The first side plate 012 and the second side plate 013 are respectively connected to both sides of the folding mechanism 011, and are rotatable 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 the flexible deformation part 021 of the flexible display screen 02 corresponds to the position of the folding mechanism 011; the flexible deformation portion 021 can be bent so that the flexible display screen 02 can be folded or unfolded with the rotation of the first side plate 012 and the second side plate 013.

Referring to fig. 1, when the electronic device 1 is in the unfolded state, an included angle between the first side plate 012 and the second side plate 013 is approximately 180 °, the flexible display screen 02 is approximately flat, and the flexible deformation portion 021 of the flexible display screen 02 is approximately flat.

Referring to fig. 2, when the electronic device 1 is in a folded state, an included angle between the first side plate 012 and the second side plate 013 is approximately 0 °, and the flexible deformation portion 021 of the flexible display screen 02 is in a bent shape.

During the production and use of the electronic device 1, the electronic device may be impacted by a foreign object or fall down, so that the flexible display screen 02 is easily damaged. In particular, the flexible deformation part 021 of the flexible display screen 02 is required to be bent, so that the structural strength is relatively low, and the flexible deformation part 021 is more easily damaged under the action of external force. For example, when the electronic device 1 is subjected to an external force, the flexible deformation portion 021 of the flexible display screen 02 and the folding mechanism 011 may collide with each other, which may easily cause damage and failure of the flexible deformation portion 021.

Referring to fig. 3, fig. 3 is a schematic view illustrating a partial structure of the electronic device 1 shown in fig. 1 in an unfolded state. The side of the flexible display screen 02 facing the folding mechanism 011 is connected with a supporting component 03, the supporting component 03 comprises two supporting thin plates 031 and a rotating piece 032 arranged between the two supporting thin 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 supporting thin plates 031 can relatively rotate based on the rotating piece 032 between the two rotating pieces, so that the supporting component 03 can be synchronously folded or unfolded along with the flexible display screen 02. The support assembly 03 may support and strengthen the flexible display 02.

The rotating member 032 includes a plurality of side-by-side strips 0321, and a gap exists between two adjacent strips 0321. In the process of rotating the electronic device 1 from the unfolded state to the folded state, the flexible deformation portion 021 of the flexible display screen 02 is gradually bent, and the plurality of strips 0321 are gradually gathered together, so as to maintain the bending form of the flexible deformation portion 021. In the process of rotating the electronic device 1 from the folded state to the unfolded state, the flexible deformation portion 021 of the flexible display screen 02 is gradually flattened, and the plurality of strips 0321 are gradually unfolded accordingly, so as to maintain the flat shape of the flexible deformation portion 021.

When the electronic device 1 receives an external force, the flexible deformation part 021 and the rotating part 032 are easy to collide with the folding mechanism 011, and the strip-shaped body 0321 of the rotating part 032 is a hard structure made of metal material for better supporting the flexible deformation part 021, so that the flexible deformation part 021 is easy to be damaged and fails, and the service life of the electronic device 1 is influenced.

In view of the above, embodiments of the present application provide a folding assembly and a terminal device including the folding assembly, which can improve the technical problem that a flexible deformation portion of a flexible display screen is easily damaged when being subjected to an external force in the related art, and improve reliability.

The terminal equipment provided by the embodiment of the application belongs to foldable electronic equipment, namely electronic equipment capable of realizing folding and unfolding. The terminal device may be a mobile phone, a tablet computer, a Laptop (Laptop), a Notebook (Notebook PC), a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a wearable device (e.g., a wristwatch), a vehicle-mounted device, an augmented Reality (Augmented Reality, AR)/Virtual Reality (VR) device, etc., but is not limited thereto.

Referring to fig. 4 and fig. 5, fig. 4 is a schematic structural diagram of a terminal device 1000 in an unfolded state according to some embodiments of the present application, and fig. 5 is a schematic partial structural diagram of the terminal device 1000 in an unfolded state shown in fig. 4. In the embodiment of the present application, the terminal device 1000 is taken as a mobile phone for description.

Terminal device 1000 includes folding assembly 100, spindle mechanism 200, first housing 300, second housing 400, and folding screen 500, wherein:

The first housing 300 and the second housing 400 are rotatably connected by the rotation shaft mechanism 200; that is, the first housing 300 and the second housing 400 can be relatively rotated based on the rotation shaft mechanism 200 to be relatively moved together to be rotated to a folded state and relatively moved apart to be rotated to be unfolded.

It will be appreciated that both the first housing 300 and the second housing 400 may be a center frame, and that the specific shape and configuration may be set as desired. The rotation shaft mechanism 200 may be of various structures as long as it allows the first and second housings 300 and 400 connected thereto to rotate relatively.

The folding screen 500 is provided on the first and second cases 300 and 400 to be capable of folding or unfolding as the first and second cases 300 and 400 are rotated. The position of the foldable portion 510 of the folding screen 500 corresponds to the position of the spindle mechanism 200. The foldable portion 510 is a portion capable of being bent, and has flexibility such that the folding screen 500 can be folded by bending the foldable portion 510 when the first housing 300 and the second housing 400 are rotated relatively. The foldable portion 510 may have a drop shape or a U shape when the folding screen 500 is in a folded state, but is not limited to this shape.

It will be appreciated that the folding screen 500 may be flexible or rigid at the portion of the screen corresponding to the first housing 300; the folding screen 500 may have flexibility or rigidity corresponding to a screen portion of the second housing 400.

The folding assembly 100 is connected to the back of the folding screen 500, and the folding assembly 100 is located between the folding screen 500 and the hinge mechanism 200. The folding assembly 100 can be folded or unfolded simultaneously with the folding or unfolding of the folding screen 500. The back surface of the folding screen 500 is the surface facing the rotating shaft mechanism 200, and can be regarded as a non-display surface of the folding screen 500; the front surface of the folding screen 500 is the surface facing away from the spindle mechanism 200, that is, the display surface of the folding screen 500 for displaying images.

When terminal device 1000 is in the unfolded state, folding screen 500 and folding assembly 100 are in the unfolded state, and first housing 300 and second housing 400 are substantially in the same plane, i.e., the angle between first housing 300 and second housing 400 is substantially 180 °. At this time, the folding screen 500 is substantially flat, so that the terminal device 1000 has a large display area. It should be appreciated that the angle between first housing 300 and second housing 400 is not limited to an absolute 180 ° when terminal device 1000 is in the deployed state; the included angle between the first housing 300 and the second housing 400 may be greater than or less than 180 °, but close to 180 °, for example, the included angle may range from 165 ° to 190 ° (e.g., 170 °, 173 °, 175 °, 182 °, 185 °, etc., but not limited thereto), and the folding screen 500 may be unfolded as well.

When terminal device 1000 is in a folded state, folding screen 500 and folding assembly 100 are in a folded state, first housing 300 and second housing 400 are substantially parallel, i.e., the angle between first housing 300 and second housing 400 is substantially 0 °. At this time, the folding screen 500 is folded by its foldable portion 510 to facilitate the storage of the terminal device 1000. It should be understood that when terminal device 1000 is in a folded state, it is not limited to first housing 300 being absolutely parallel to second housing 400, and the angle between first housing 300 and second housing 400 may be greater than 0 °, but close to 0 °, for example, the angle may range from 0 ° to 15 ° (e.g., 1 °,2 °,3 °,5 °,10 °, etc., but not limited thereto), and folding of folding screen 500 may also be achieved.

In some embodiments, referring to fig. 4, terminal device 1000 may be an in-turned type terminal device, and folding screen 500 is an in-turned type folding screen. After folding the folding screen 500, the folding screen 500 is positioned inside the folding assembly 100.

Of course, in other embodiments, terminal device 1000 can be an out-folded terminal device, and folding screen 500 can be an out-folded 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 inside the folding screen 500.

In some embodiments, referring to fig. 5, the spindle mechanism 200 includes a spindle 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 disposed on the shaft cover 210, and the base 220 may provide support and mounting for the support door panel 230, the first swing arm 240, and the second swing arm 250. The support door panel 230 is disposed on the base 220 and can be used to support the foldable portion 510 of the folding screen 500. The first swing arm 240 and the second swing arm 250 are rotatably connected to both sides of the base 220, respectively, to be capable of being rotated to a folded state or an unfolded state based on the base 220. 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 the first and second swing arms 240 and 250 are driven to rotate simultaneously when the first and second housings 300 and 400 rotate.

When the terminal device 1000 is in the unfolded state, the supporting door plate 230, the first swing arm 240 and the second swing arm 250 can all support the foldable portion 510 of the folding screen 500, so that the foldable portion 510 is stable and flat. When the terminal device 1000 is in a folded state, the first swing arm 240 and the second swing arm 250 can rotate and draw together based on the base 220, and a receiving space can be formed between the support door plate 230, the first swing arm 240 and the second swing arm 250 for receiving the folded foldable portion 510.

Alternatively, the first swing arm 240 and the second swing arm 250 may be coupled to the base 220 in a variety of ways.

Illustratively, the two sides of the base 220 are provided with sliding grooves, the first swing arm 240 and the second swing arm 250 are provided with sliding rails, and the first swing arm 240 and the second swing arm 250 are respectively in sliding fit with the sliding grooves through the sliding rails, so that the sliding rails slide along the track of the sliding grooves while the first swing arm 240 and the second swing arm 250 rotate based on the base 220.

Illustratively, the first swing arm 240 and the second swing arm 250 may also be connected to the base 220 through a rotation shaft, respectively, and can drive the support door panel 230 to lift. When the first swing arm 240 and the second swing arm 250 are rotated to the unfolded state, the supporting door plate 230 is driven to ascend (move towards the foldable portion 510) to support the foldable portion 510, and when the first swing arm 240 and the second swing arm 250 are rotated to the folded state, the supporting door plate 230 is driven to descend (move away from the foldable portion 510) to avoid the folded foldable portion 510.

Next, description will be given of a folding assembly 100 provided in an embodiment of the present application.

Referring to fig. 5 to fig. 7, fig. 6 is a schematic perspective view illustrating a folding assembly 100 in an unfolded state according to some embodiments of the present application, and fig. 7 is a schematic perspective view illustrating the folding assembly 100 in a folded state according to fig. 6. The folding assembly 100 includes a first support 10, a second support 20, and a folding member 30. The second support 20 is spaced apart from the first support 10. The folder 30 is disposed between the first support 10 and the second support 20. The first support 10 and the second support 20 are capable of relative rotation based on the fold 30 to switch the folding assembly 100 between the unfolded state and the folded state. That is, the folding member 30 itself may be folded or folded such that the first support 10 and the second support 20 on both sides of the folding member 30 can rotate about the folding member 30 as a whole. Wherein, the folder 30 includes an elastic body 31, and the elastic body 31 is used for buffering external force.

The first support member 10 and the second support member 20 are connected to the rear surface of the folding screen 500, and can support the folding screen 500, and can play a role in stabilizing the form and reinforcing the folding screen 500. Alternatively, the first support 10 and the second support 20 may be a sheet-like structure, a plate-like structure, or a layered structure of various shapes so as to be attached to the rear surface of the folding screen 500. The first support 10 and the second support 20 may be made of various hard materials, for example, a metal material (e.g., stainless steel, etc.), an alloy, etc., but are not limited thereto. The shape of the first support 10 may be the same as or different from the shape of the second support 20.

The position of the folding member 30 corresponds to the position of the foldable portion 510 of the folding screen 500, while the position of the folding member 30 corresponds to the position of the spindle mechanism 200, the folding member 30 is located between the foldable portion 510 and the spindle mechanism 200, and the elastic body 31 is located between the foldable portion 510 and the spindle mechanism 200. The folding member 30 can be folded or unfolded synchronously with the folding or unfolding of the foldable portion 510, and can function to support the foldable portion 510. The folding member 30 may be connected to the first support member 10 and the second support member 20, but may be not directly connected (e.g., have a gap) to at least one of the first support member 10 and the second support member 20.

The elastic body 31 is a structure having elasticity and is capable of elastic deformation. The elastic body 31 may include a soft material to have flexibility, which facilitates bending deformation of the folder 30. For example, the elastic body 31 may be a structure body including a polymer having elasticity, wherein the polymer having elasticity may be Rubber, silicone Rubber, soft PVC (Polyvinyl chloride ), TPE (Thermoplastic Elastomer, thermoplastic elastomer), TPU (Thermoplastic Urethane, thermoplastic polyurethane elastomer), TPR (Thermo-Plastic-Rubber), TPV (Thermoplastic Vulcanizate, thermoplastic vulcanized Rubber), or the like, but is not limited thereto. The elastic body 31 may have various shapes, for example, a continuous integral structure, or a discrete structure including a plurality of sub-elastic bodies.

Referring to fig. 6, when the folding assembly 100 is in the unfolded state, the folding assembly 100 is substantially flat, and the first supporting member 10 and the second supporting member 20 are substantially in the same plane, i.e. the included angle between the first supporting member 10 and the second supporting member 20 is substantially 180 °. It should be appreciated that the angle between the first support 10 and the second support 20 is not limited to an absolute 180 ° when the folding assembly 100 is in the unfolded state; the included angle between the first support 10 and the second support 20 may be greater or less than 180 °, but close to 180 °, for example, the included angle may range from 165 ° to 190 ° (e.g., 170 °, 173 °, 175 °, 182 °, 185 °, etc., but is not limited thereto).

Referring to fig. 7, when the folding assembly 100 is in the folded state, the foldable portion 510 is folded, so that the first support 10 and the second support 20 are disposed opposite to each other. In some cases, the first support 10 and the second support 20 may be substantially parallel, i.e. the angle between the first support 10 and the second support 20 is substantially 0 °. It should be appreciated that when the folding assembly 100 is in the folded state, it is not limited that the first support 10 and the second support 20 are absolutely parallel, and the included angle between the first support 10 and the second support 20 may be greater than 0 °, but close to 0 °, for example, the included angle may range from 0 ° to 20 ° (e.g., 1 °,2 °,3 °,5 °,10 °, 12 °, 15 °,18 °, 20 °, etc., but not limited thereto).

As can be seen from the above, the folding assembly 100, the first supporting member 10, the second supporting member 20 and the folding member 30 according to the embodiment of the application can support the folding screen 500, so as to improve the stability of the form of the folding screen 500; the foldable part 510 of the folding screen 500 can be supported by the folder 30, and since the folder 30 includes the elastic body 31, when the foldable part 510 of the folding screen 500 is subjected to an external force (e.g., the terminal device 1000 is bumped or dropped, resulting in collision between the foldable part 510 and the folder 30 and the hinge mechanism 200), the external force can be buffered by the elastic body 31, so as to reduce the possibility of damage to the foldable part 510 of the folding screen 500.

In some embodiments, the elastic modulus of the elastic body 31 is smaller than the elastic modulus of the first support 10 and the second support 20, that is, the stiffness of the elastic body 31 is smaller than the stiffness of the first support 10 and the second support 20, so that the first support 10 and the second support 20 have a certain stiffness so as to support the portion of the folding screen 500 except for the foldable portion 510, so that the portion except for the foldable portion 510 can be more stably flat, thereby facilitating display; the elastic body 31 may have a certain flexibility to facilitate buffering the external force. Wherein the modulus of elasticity can be characterized by Young's modulus.

In some embodiments, referring to fig. 6 and 7, the folder 30 further includes a plurality of first connecting strips 32. When the folding assembly 100 is in the unfolded state, the direction of the first support member 10 facing the second support member 20 is defined as a first direction a, the plurality of first connecting strips 32 are sequentially arranged along the first direction a, and the length direction L1 of the first connecting strips 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 may be connected to all the first connection bars 32 at the same time, or may be connected to only one or more of the first connection bars 32 and not connected to the remaining one or more first connection bars 32. The elastic modulus of the elastic body 31 is smaller than the elastic modulus of the first connecting bar 32, that is, the rigidity of the elastic body 31 is smaller than the rigidity of the first connecting bar 32.

The first connecting strip 32 is an elongated structure having a length substantially greater than its width and height. The first connecting strip 32 may be a rectangular strip with a regular shape or a strip-like structure with an 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, and the thickness direction H1 of the first connecting strip 32 is the thickness direction H1 of the first support 10 and the thickness direction H1 of the second support 20; in the terminal device 100, the thickness direction H1 of the first support 10, that is, 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 longitudinal direction L1 of the first connecting strip 32, the thickness direction H1 of the first connecting strip 32, and the width direction S1 of the first connecting strip 32 are perpendicular to each other. It is to be understood that the "sequential arrangement" is not limited to the uniform arrangement, and the respective first connection bars 32 may or may not be uniformly arranged along the first direction a.

During the process of turning the folding assembly 100 from the unfolded state to the folded state, the folding member 30 is gradually folded, and the first connecting strips 32 can be gradually gathered. During the rotation of the folding assembly 100 from the folded state to the unfolded state, the folding members 30 are gradually flattened, and each of the first connecting strips 32 is gradually unfolded.

The arrangement of the plurality of first connecting strips 32 is not only beneficial to bending deformation of the folding member 30, but also can improve the integral rigidity formed by combining the elastic body 31 because the elastic modulus is greater than that of the elastic body 31, further improve the supporting effect and the protecting effect on the foldable part 510, and is beneficial to improving the stability of the foldable part 510 in a bending state or a flat state, namely, the foldable part 510 is better maintained in the bending state or the flat state.

Alternatively, in some embodiments, referring to fig. 6 and 7, a first space is formed between two adjacent first connecting strips 32, the elastic body 31 includes a first filling portion 3111, and the first filling portion 3111 is disposed in at least one first space, that is, the first filling portion 3111 may be filled in all the first spaces or 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 portion 3112, and the second filling portion 3112 is disposed between the first support 10 and the first connecting bar 32. The elastic body 31 includes a third filling portion 3113, and the third filling portion 3113 is disposed between the second support 20 and the first connecting bar 32.

It will be appreciated that the first fill portion 3111, the second fill portion 3112 and the third fill portion 3113 are all part of the elastomer 31, and are all capable of elastic deformation.

In this way, the filling of the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113 not only can improve the structural reliability of the combination of the elastic body 31, the first connecting strip 32, the first supporting member 10 and the second supporting member 20, but also can 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 supporting member 10 and the relative movement between the first connecting strip 32 and the second supporting member 20, thereby effectively reducing the possibility of unstable form of the foldable portion 510 caused by the relative movement or dislocation between the two adjacent first connecting strips 32, the first connecting strip 32 and the first supporting member 10 and the first connecting strip 32 and the second supporting member 20, so as to facilitate improving the stability of the foldable portion 510 when in a bent form, and simultaneously, the elastic body 31 can be distributed relatively widely, so as to facilitate improving the effect of buffering external force.

Optionally, referring to fig. 8, fig. 8 is a schematic perspective view of a folding assembly 100 in an unfolded state according to another embodiment of the application, and the first filling portion 3111 may completely fill the first space, so as to improve the effect of limiting and buffering. Of course, the first filling portion 3111 may fill only a part of the first space and leave another part unfilled, as shown in fig. 6.

Likewise, the second filling part 3112 may completely fill the space between the first support 10 and the first connection bar 32, for example, as shown in fig. 8; it is also possible to fill only a part of the space between the first support 10 and the first connection strip 32 and leave another part of the space unfilled, for example as shown in fig. 6.

Likewise, the third filling part 3113 may completely fill the space between the second support 20 and the first connection bar 32, for example, as shown in fig. 8; it is also possible to fill only a part of the space between the second support 20 and the first connection strip 32 and leave another part of the space unfilled, for example as shown in fig. 6.

In other embodiments, at least one of the first filling portion 3111, the second filling portion 3112, and the third filling portion 3113 may not be provided. Fig. 9 shows, by way of example, a schematic illustration of the folding assembly 100 in the unfolded state, without the first filling part 3111, the second filling part 3112 and the third filling part 3113 being provided.

Alternatively, in some embodiments, referring to fig. 6 and 9, the elastic body 31 includes a base portion 312, and the base portion 312 is located at one side of the first connecting bar 32 in the thickness direction H1. In terminal device 1000, base 312 can be located on the side of first connector strip 32 facing hinge mechanism 200 or on the side of first connector strip 32 facing folding screen 500. It can be appreciated that the base 312 is a part of the elastic body 31, and has an elastic modulus smaller than that of the first connecting strip 32, and can be elastically deformed to play a role of buffering external force.

Alternatively, referring to fig. 6 and 7, the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113 may be connected to the base 312, so as to facilitate the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113 to be connected integrally by the base 312, so as to reduce the possibility of falling off of the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113, improve the overall reliability of the elastomer 31, and improve the reliability of the connection between the elastomer 31 and the first connecting strip 32. Meanwhile, the first filling portion 3111, the second filling portion 3112, the third filling portion 3113 and the base 312 are all capable of elastic deformation, which is advantageous for improving the effect of buffering external force.

Of course, in other embodiments, at least one of the first fill portion 3111, the second fill portion 3112, and the third fill portion 3113 may not be connected to the base 312.

Alternatively, referring to fig. 6 and 7, the base 312 may have a layered structure or a sheet structure, so as to have a larger area, be widely distributed, and be more beneficial to improving the effect of the elastic body 31 on buffering the external force.

Of course, in other embodiments, the base 312 may also include a plurality of sub-bases disposed at intervals, and the sub-bases may be a sheet structure, a plate structure, a bar structure, a rod structure, or the like, but is not limited thereto.

Alternatively, referring to fig. 6 and 9, when folding assembly 100 is in the unfolded state, the surface of base 312 facing away from first connecting strip 32 may be substantially flush with the lower surfaces of first support 10 and second support 20, and not easily interfere with other components of terminal device 1000 (e.g., spindle mechanism 200).

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

In other embodiments, the elastic body 31 may not be provided with the base 312, but may be provided with at least one of the first filling portion 3111, the second filling portion 3112, and the third filling portion 3113. Fig. 10 is a schematic view schematically showing the structure of the folding assembly 100 in the unfolded state without the base 312.

Optionally, in some embodiments, referring to fig. 11, fig. 11 is a schematic perspective view illustrating a folding assembly 100 in an unfolded state according to other embodiments of the present application. The folder 30 also includes a plurality of second connecting strips 33. When the folding assembly 100 is in the unfolded state, the plurality of second connection strips 33 are sequentially arranged along the first direction a, and the length direction of the second connection strips 33 is perpendicular to the first direction a. Each first connecting bar 32 forms a first connecting bar set 320 and each second connecting bar 33 forms a second connecting bar set 330. When the folding assembly 100 is in the unfolded state, the first and second link groups 320 and 330 are spaced apart in 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 may be connected to all of the second connection bars 33 at the same time, or may be connected to only one or more of the second connection bars 33, and may not be connected to the remaining one or more second connection bars 33. The elastic modulus of the elastic body 31 is smaller than the elastic modulus of the second connecting bar 33, that is, the rigidity of the elastic body 31 is smaller than the rigidity of the second connecting bar 33.

The second connecting strip 33 is a strip-like structure having a length substantially greater than its width and height. The second connecting strip 33 may be a rectangular strip with a regular shape or a strip-like structure with an 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. It is understood that the shape and configuration of the second connecting bar 33 may be the same as or different from the shape and configuration of the first connecting bar 32. The second connection bars 33 may or may not be uniformly arranged along the first direction a.

During the process of turning the folding assembly 100 from the unfolded state to the folded state, the folding member 30 is gradually folded, each first connecting strip 32 may be gradually gathered, and each second connecting strip 33 may be gradually gathered. During the rotation of the folding assembly 100 from the folded state to the unfolded state, the folding member 30 is gradually flattened, each of the first connecting strips 32 may be gradually unfolded, and each of the second connecting strips 33 may be gradually unfolded.

So set up, because when folding subassembly 100 is in the unfolded state, first connecting strip group 320 and second connecting strip group 330 are along the thickness direction H1 interval setting of first support 10, be equivalent to setting up the connecting strip group that two rows of intervals set up promptly, and because the elastic modulus of second connecting strip 33 is greater than the elastic modulus of elastomer 31, can further improve the rigidity and the structural reliability of folded piece 30, not only can improve folded position 510 and be in the stability when buckling or flattening the form, but also can improve folded piece 30 and to folded position 510's protective effect, reduce folded position 510 and pivot mechanism 200 and bump and lead to the possibility of inefficacy.

Optionally, referring to fig. 11, the second connecting strip 33 is disposed opposite to the first connecting strip 32. When the folding assembly 100 is in the unfolded state, the second connection bar 33 is disposed opposite to the first connection bar 32 in the thickness direction H1 of the first support 10.

So set up, the shaping or the installation of second connecting strip 33 and first connecting strip 32 of being convenient for are arranged, and moreover, the space that forms between two adjacent second connecting strips 33 and the space that forms between two adjacent first connecting strips 32 also set up relatively, do benefit to folding piece 30 to buckle.

Of course, the second connecting bar 33 and the first connecting bar 32 are not limited to being disposed opposite to each other in the thickness direction H1 of the first support 10. In other embodiments, referring to fig. 12, fig. 12 is a schematic perspective view illustrating a folding assembly 100 in an unfolded state according to other embodiments of the present application. When the folding assembly 100 is in the unfolded state, the at least one second connecting strip 33 is located between two adjacent first connecting strips 32 along the projection of the thickness direction H1 of the first supporting member 10, which can also be understood as that the second connecting strip 33 is offset from the first connecting strip 32. In this way, the overall structural reliability of the folded member 30 is advantageously improved, and the supporting effect and the protecting effect of the folded member 30 on the foldable portion 510 are further advantageously improved.

Optionally, referring to fig. 11 and 12, the elastic body 31 further includes a base 312, and the base 312 is located between the first connecting bar group 320 and the second connecting bar group 330.

So set up, the first connecting strip group 320 is separated from the second connecting strip group 330 by the base 312, when the folding screen 500 collides with the rotating shaft mechanism 200, the first connecting strip group 320 and the second connecting strip group 330 can transmit force to the base 312, so as to buffer through the base 312, avoid the first connecting strip group 320 and the second connecting strip group 330 from directly colliding, and improve the effect of buffering external force of the folding piece 30. In addition, the base 312 can be connected to the first connecting strip set 320 and the second connecting strip set 330 at the same time, which is beneficial to improving the structural reliability of the folded member 30.

Alternatively, referring to fig. 11 and 12, the base 312 may be connected to each of the first connecting strips 32 and each of the second connecting strips 33, so as to improve the effect of buffering the external force of the elastic body 31. Of course, the base 312 may also be unconnected to the at least one first connecting strip 32 and/or the at least one second connecting strip 33.

Optionally, referring to fig. 11 and 12, a second space is formed between two adjacent second connecting strips 33, and the elastic body 31 further includes a fourth filling portion 3131, where the fourth filling portion 3131 is connected to the base 312 and disposed in at least one second space. The elastic body 31 further includes a fifth filling portion 3132, and the fifth filling portion 3132 is connected to the base 312 and disposed between the first support 10 and the second connecting bar 33. The elastic body 31 further includes a sixth filling portion 3133, and the sixth filling portion 3133 is connected to the base 312 and disposed between the second support 20 and the second connecting bar 33.

It is understood that the fourth filling portion 3131, the fifth filling portion 3132 and the sixth filling portion 3133 are all part of the elastic body 31 and can be elastically deformed.

In this way, the filling of the fourth filling portion 3131, the fifth filling portion 3132 and the sixth filling portion 3133 not only can improve the structural reliability of the combination of the elastic body 31, the second connecting strips 33, the first supporting member 10 and the second supporting member 20, but also can limit and buffer the relative movement between the two adjacent second connecting strips 33, the relative movement between the second connecting strips 33 and the first supporting member 10 and the relative movement between the second connecting strips 33 and the second supporting member 20, thereby effectively reducing the possibility of the relative movement between the two adjacent second connecting strips 33, the first connecting strips 32 and the first supporting member 10 and the first connecting strips 32 and the second supporting member 20, so as to facilitate improving the stability of the foldable part 510 in the bending state, and simultaneously, the distribution of the elastic body 31 is relatively wide, and the effect of buffering external force is facilitated to be improved.

In addition, by connecting the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133 together by the base portion 312, the possibility of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133 falling off can be reduced, and the overall reliability of the elastic body 31 and the reliability of the connection of the elastic body 31 and the second connecting bar 33 can be improved; further, by the engagement of the base 312 with the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133, the elastic body 31 has a more excellent external force buffering effect.

Optionally, the fourth filling portion 3131 may completely fill the second space, so as to improve the effect of limiting and buffering; of course, the fourth filling portion 3131 may fill only a part of the second space and leave another part unfilled. Similarly, the fifth filling portion 3132 may completely fill the space between the first support 10 and the second connecting bar 33, or may fill only a part of the space between the first support 10 and the second connecting bar 33 and leave another part of the space unfilled. The sixth filling portion 3133 may completely fill the space between the second support 20 and the second connecting bar 33, or may fill only a part of the space between the second support 20 and the second connecting bar 33 and leave another part of the space unfilled.

In other embodiments, at least one of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133 may not be provided. Fig. 13 is a schematic perspective view illustrating a folded assembly 100 in an unfolded state, in which none of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133 is provided.

Alternatively, in some embodiments, referring to fig. 11, when 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, each second connecting strip 33 is uniformly arranged along the first direction a, and the distance between any two adjacent second connecting strips 33 is substantially the same.

By the arrangement, the overall structural strength of the folding piece 30 is uniform, the supporting effect and the protecting effect on the foldable part 510 can be improved, and the stability of the foldable part 510 in a bending state and a flattening state can be improved.

Optionally, in other embodiments, referring to fig. 14, fig. 14 is a schematic perspective view illustrating a folding assembly 100 in an unfolded state according to other embodiments of the present application. The folder 30 includes a first region 301, a second region 302, and a third region 303, the first region 301 being located at one side of the first support 10, the second region 302 being located at one side of the second support 20, the third region 303 being 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 connection bar 32, and the third region 303 is not provided with the first connection bar 32. The first region 301 and the second region 302 are each provided with at least one second connecting bar 33, and the third region 303 is not provided with a second connecting bar 33.

One side portion of the foldable portion 510 adjacent to the first support 10 is defined as a first bending portion 5101, and the other side portion of the foldable portion 510 adjacent to the second support 20 is defined as a second bending portion 5102, as shown in fig. 5. The first bending portion 5101 and the second bending portion 5102 are transition portions between the foldable portion 510 and other portions of the folding screen 500, and when the foldable portion 510 is subjected to an external force, the first bending portion 5101 and the second bending portion 5102 are generally most easily damaged, especially when the folding screen 500 is in a folded state, the foldable portion 510 is in a bent shape, and when the foldable portion 500 is subjected to an external force, the first bending portion 5101 and the second bending portion 5102 are generally portions with concentrated stress, and are most easily damaged, especially when the foldable portion 510 is in a water drop shape. The position of the first region 301 corresponds substantially to the position of the first bending portion 5101, and the position of the second region 302 corresponds substantially to the position of the second bending portion 5102.

By arranging at least one first connecting strip 32 and at least one second connecting strip 33 in the first area 301 and the second area 302, and not arranging the first connecting strip 32 and the second connecting strip 33 in the third area 303, the strength of the part of the folded piece 30 close to the first supporting piece 10 and the strength of the part close to the second supporting piece 20 are higher than that of the middle part, the two side parts of the foldable part 510 can be effectively supported and protected, the possibility that the most damaged part of the foldable part 510 is damaged is reduced, the safety of the folded screen 500 is improved, and the third area 303 can save materials and reduce weight because the first connecting strip 32 and the second connecting strip 33 are not arranged.

Of course, in other embodiments, when the folding member 30 is not provided with the second connecting strip 33, it may be that 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 the first connecting strip 32, and fig. 15 is a schematic perspective view exemplarily showing the folding assembly 100 in the unfolded state without the second connecting strip 33.

In some embodiments, referring to fig. 6 and 8, the first support 10 includes a first side 11, the first side 11 facing the second support 20 when the folding assembly 100 is in the unfolded state. The first side 11 is provided with a first groove 1101; the elastic body 31 includes a first connecting portion 3141, and the first connecting portion 3141 is disposed in the first groove 1101. It will be appreciated that the first connecting portion 3141 is part of the elastic body 31 and can also be elastically deformed.

In this way, since the elastic body 31 is connected to the first groove 1101 of the first support 10 through the first connecting portion 3141, the connection firmness of the elastic body 31 and the first support 10 can be improved, and thus the connection reliability of the folder 30 and the first support 10 can be improved.

Alternatively, referring to fig. 6 and 8, the first connecting portion 3141 may be connected to the base 312, and may also be considered that the first connecting portion 3141 is formed by extending the base 312 toward the first supporting member 10. The first connecting portion 3141 and the base portion 312 may be formed as an integrally formed one-piece structure, and the structural reliability is high.

Alternatively, referring to fig. 6 and 8, a first gap 101 is formed between an end of the first connecting portion 3141 and an inner wall of the first groove 1101. It should be appreciated that the width or size of the first void 101 may be set as desired; when the width of the first space 101 is small, it may not be visually apparent, but it is considered that the first space 101 is formed between the end of the first connecting portion 3141 and the inner wall of the first groove 1101 as long as the end of the first connecting portion 3141 is not completely adhered to the inner wall of the first groove 1101.

So set up, when folding subassembly 100 switches between folded state and expanded state, first space 101 can provide and dodge the space, can hold the extrusion deformation volume when first connecting portion 3141 takes place to warp, can reduce the possibility that leads to first connecting portion 3141 to take place to break away from with first support 10 because of extrusion deformation volume to and reduce the possibility that leads to elastomer 31 to take place to arch because of extrusion deformation volume, and then improve the stability that elastomer 31 is connected with first support 10. Meanwhile, since the first connecting portion 3141 and the first supporting member 10 are made of different materials, when the first connecting portion 3141 and the first supporting member 10 are affected by external environment (for example, affected by temperature), the expansion amount of the first connecting portion 3141 is different from that of the first supporting member 10, and the first gap 101 can accommodate the expansion amount generated by the first connecting portion 3141, so that the possibility that the first connecting portion 3141 and the first supporting member 10 are separated due to the expansion amount can be reduced, and the possibility that the elastic body 31 is arched due to the expansion amount can be reduced.

Alternatively, in some embodiments, referring to fig. 6 and 8, the second support 20 includes a second side 21, the second side 21 facing the first support 10 when the folding assembly 100 is in the unfolded state, i.e., the second side 21 is disposed opposite the first side 11. The second side 21 is provided with a second slot 2101; the elastic body 31 further includes a second connecting portion 3142, and the second connecting portion 3142 is disposed in the second groove 2101. It will be appreciated that the second connecting portion 3142 is part of the elastic body 31 and is also capable of elastic deformation.

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 connection firmness of the elastic body 31 and the second support 20 can be improved, and the connection reliability of the folded piece 30 and the second support 20 can be improved.

Alternatively, referring to fig. 6 and 8, the second connecting portion 3142 may be connected to the base 312, and may also be considered that the second connecting portion 3142 is formed by extending the base 312 toward the second supporting member 20. The second connecting portion 3142 and the base portion 312 may be an integrally formed one-piece structure, and the structural reliability is high.

Alternatively, referring to fig. 6 and 8, a second gap 102 is formed between an end of the second connecting portion 3142 and an inner wall of the second groove 2101. It should be appreciated that the width or size of the second void 102 may be set as desired; when the width of the second space 102 is small, it may not be visually apparent, but the second space 102 is formed between the end of the second connecting portion 3142 and the inner wall of the second groove 2101 as long as the end of the second connecting portion 3142 is not completely adhered to the inner wall of the second groove 2101.

So set up, when folding subassembly 100 switches between folded state and expanded state, not only first space 101 can provide and dodge the space, can hold the extrusion deformation volume and the expansion volume that first connecting portion 3141 produced when first connecting portion 3141 takes place to warp by external environment influence, and second groove 2101 also can provide and dodge the space, can hold the extrusion deformation volume and the expansion volume that second connecting portion 3142 produced when second connecting portion 3142 takes place to warp by external environment influence, can reduce the possibility that second connecting portion 3142 takes place to break away from with second support member 20, can further reduce the possibility that the elastic body 31 takes place the arch phenomenon because of extrusion deformation volume or expansion volume, thereby improve the stability of folding member 30.

There are various ways of mating or connecting the elastic body 31 with the first connecting strip 32, and this will be described by way of example.

Optionally, in some embodiments, referring to fig. 6, the elastomer 31 is a spacer; that is, the elastic body 31 is a cushion structure provided separately from the first connecting bar 32, that is, the elastic body 31 after being molded is connected to the first connecting bar 32.

Alternatively, the elastic body 31, which is a spacer, may be directly disposed on the first connection bar 32, or may be connected to the first connection bar 32 by an adhesive or the like.

Alternatively, in other embodiments, referring to fig. 8, the elastic body 31 is a coating applied on the first connecting strip 32; that is, an unshaped coating material (in the form of a fluid, for example, a glue of a plurality of materials) is applied to the first connecting strip 32, and the coating material is cured to form the coated elastic body 31. Thus, the elastic body 31 is easy to be processed and molded, and the adhesive is not needed to be used for bonding.

Alternatively, in other embodiments, referring to fig. 11 and 12, the elastic body 31 and the first connecting strip 32 are integrally formed by injection molding; that is, the elastic body 31 is formed on the first connecting bar 32 by injection molding, so that the elastic body 31 and the first connecting bar 32 can be sufficiently contacted, and the reliability of the connection between the elastic body 31 and the first connecting bar 32 can be improved. For example, the first connecting bar 32 may be disposed in a mold, and then a material for forming the fluid body of the elastic body 31 may be injected into the mold, and after the curing molding, the elastic body 31 may be formed and the elastic body 31 may be in close contact with the first connecting bar 32.

It is understood that, regarding the fitting relationship or connection manner between the elastic body 31 and the second connection strip 33, the fitting relationship or connection manner between the elastic body 31 and the first connection strip 32 described above may be adopted. For example, when the elastic body 31 is a spacer, it may be adhered or directly disposed on the second connecting strip 33, when the elastic body 31 is a coating, it may be coated on the second connecting strip 33, and the elastic body 31 and the second connecting strip 33 may be an injection-molded integrated structure.

Referring to fig. 16 to 19, fig. 16 is a schematic perspective view illustrating a folding assembly 100 in an unfolded state according to other embodiments of the present application, and fig. 17 is a schematic view illustrating a structure of the folding assembly 100 shown in fig. 16 when the folding assembly is mated with a folding screen 500 and in a folded state; fig. 18 is a schematic perspective view illustrating a folding assembly 100 in an unfolded state according to still other embodiments of the present application, and fig. 19 is a schematic perspective view illustrating a folding assembly 100 shown in fig. 18 when the folding assembly 100 is mated with a folding screen 500 and in a folded state.

In some embodiments, the first support 10 includes a first face 12 and a second face 13, the first face 12 and the second face 13 being disposed opposite along the 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.

It will be appreciated that in terminal device 1000, when first face 12 is facing folding screen 500, first protrusion 3151 protrudes towards folding screen 500, and second face 13 is facing away from folding screen 500, as shown, for example, in fig. 16 and 17. When the second face 13 faces the folding screen 500, the first face 12 faces away from the folding screen 500, and the first protrusion 3151 protrudes away from the folding screen 500, as shown in fig. 18 and 19. The first protruding portion 3151 is a part of the elastic body 31, and is elastically deformable.

It is understood that the first protrusion 3151 may be various protruding structures having regular or irregular shapes, such as a bar structure, a column structure, a bulge structure, a cone structure, a sphere structure, etc., but is not limited thereto.

So set up, when folding screen 500 receives external force, for example, when the mutual collision takes place between folding screen 500 and pivot mechanism 200, because first protruding portion 3151 protrusion in first face 12, can be forced deformation at first, can make elastomer 31 atress at first in order to cushion external force, do benefit to the effect that improves buffering external force, first protruding portion 3151 can play the effect of spring.

Alternatively, referring to fig. 16 and 18, the first protruding portion 3151 may be connected to the base 312, where the first protruding portion 3151 protrudes from the surface of the base 312, and the base 312 may provide support for the first protruding portion 3151, and the force applied by the first protruding portion 3151 may also be transferred to the base 312 to further buffer the external force through the base 312.

Optionally, referring to fig. 16, at least one of the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113 may be provided with a first protruding portion 3151, and the first protruding portion 3151 may be transferred to at least one of the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113 when being stressed, so as to further buffer the external force by at least one of the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113. Alternatively, referring to fig. 18, at least one of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133 is provided with a first protruding portion 3151, and the first protruding portion 3151 can be transferred to at least one of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133 when being stressed, so as to further buffer the external force through at least one of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133.

Alternatively, the first protruding portion 3151 may protrude from the outer surface of the first connecting strip 32 (for example, as shown in fig. 16), or protrude from the outer surface of the second connecting strip 33 (for example, as shown in fig. 18), so that the first protruding portion 3151 is more beneficial to first stress, and the effect of buffering the external force is improved.

Alternatively, when the first protrusion 3151 protrudes toward the folding screen 500, the first protrusion 3151 may be adhered to the foldable portion 510 of the folding screen 500 by adhesive, so as to improve the supporting and protecting effects of the foldable portion 510. Of course, in other embodiments, the first protrusion 3151 may not be adhered to the foldable portion 510 of the folding screen 500, for example, may be disposed in direct contact.

Alternatively, in some embodiments, referring to fig. 16 and 18, the number of the first protruding portions 3151 is plural, and a first gap 3001 is formed between two adjacent first protruding portions 3151.

It is understood that one first gap 3001 may be formed when the number of the first protrusions 3151 is two, and at least two first gaps 3001 may be formed when the number of the first protrusions 3151 is three or more. The first protrusions 3151 may be uniformly arranged, and the width or size of the first gap 3001 may be substantially the same; the first protrusions 3151 may also be unevenly arranged, and there are at least two first gaps 3001 having different widths or sizes.

So configured, 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 portion 3151 is first stressed and can deform to resist the external force, and the first gap 3001 can accommodate the deformation amount generated by the first protruding portion 3151, so that the first protruding portion 3151 can deform sufficiently to resist the external force, and the effect of buffering the external force can be effectively improved; and the first protruding parts 3151 arranged at intervals are easier to deform under the stress compared with the plate-shaped structure with larger area, so that the buffer effect can be improved.

Alternatively, referring to fig. 16 and 18, the first protruding portion 3151 has a protruding strip structure; when the folding assembly 100 is in the unfolded state, the direction of the first support member 10 facing the second support member 20 is a first direction a, the plurality of first protruding portions 3151 are sequentially arranged along the first direction a, and the length direction of the first protruding portions 3151 is perpendicular to the first direction a.

The first protrusion 3151 has a long strip shape, and its length is greater than its width and thickness. The first protruding portion 3151 may be a rectangular bar with a regular shape or a rectangular bar structure with an irregular shape. When the folding assembly 100 is in the unfolded state, the thickness direction of the first protruding portion 3151 is substantially perpendicular to the first direction a, the width direction of the first protruding portion 3151 is substantially parallel to the first direction a, and the length direction of the first protruding portion 3151, the thickness direction of the first protruding portion 3151, and the width direction of the first protruding portion 3151 are perpendicular to each other. When the folder 30 includes the first connecting bar 32, the length direction of the first protruding portion 3151 is substantially parallel to the length direction L1 of the first connecting bar 32, the thickness direction of the first protruding portion 3151 is substantially parallel to the thickness direction H1 of the first connecting bar 32, and the width direction of the first protruding portion 3151 is substantially parallel to the width direction S1 of the first connecting bar 32. It is understood that the first protrusions 3151 may be uniformly arranged along the first direction a or may be unevenly arranged.

In this way, compared with the convex structure with smaller surface area, the first protruding parts 3151 with the convex structures sequentially arranged along the first direction a can increase the stress area contacted with the folding screen 500 or the rotating shaft mechanism 200, and can better support the folding screen 500 or contact with the rotating shaft mechanism 200 to buffer external force; compared with a plate-shaped structure, the deformation is facilitated to buffer external force; and the convex strip structure is convenient for processing and forming.

Referring to fig. 16 and 17, in terminal device 1000, first protruding portion 3151 protrudes toward folding screen 500, and folding member 30 is gradually folded during the rotation of folding assembly 100 from the unfolded state to the folded state, and each of first protruding portions 3151 may be gradually gathered. During the rotation of the folding assembly 100 from the folded state to the unfolded state, the folding member 30 is gradually flattened, and each of the first protrusions 3151 may be gradually unfolded.

Alternatively, in some embodiments, referring to fig. 16 and 18, each first protrusion 3151 is uniformly arranged along the first direction a when the folding assembly 100 is in the unfolded state, i.e., the distance between any adjacent two first protrusions 3151 is substantially the same.

In this way, each first protruding portion 3151 can uniformly support the foldable portion 510 or the rotating shaft mechanism 200, so that the supporting effect on the foldable portion 510 and the effect of buffering the external force can be improved, and the stability of the foldable portion 510 in the folded state and the flat state can be improved.

Alternatively, in other embodiments, referring to fig. 20 and 21, fig. 20 is a schematic perspective view illustrating a folding assembly 100 in an unfolded state according to other embodiments of the present application, and fig. 21 is a schematic perspective view illustrating a folding assembly 100 shown in fig. 20 when the folding assembly 100 is mated with a folding screen 500 and in a folded state. The folder 30 includes a first region 301, a second region 302, and a third region 303, the first region 301 being located at one side of the first support 10, the second region 302 being located at one side of the second support 20, the third region 303 being 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 protrusion 3151, and the third region 303 is not provided with the first protrusion 3151.

So set up, when collapsible position 510 is in the folded state, the part that collapsible spare 30 is close to first support piece 10 and the part that is close to second support piece 20 can all cushion external force through first protruding portion 3151, also can both receive the guard action of first protruding portion 3151 in the both sides portion (first bending portion 5101 and second bending portion 5102) of collapsible position 510, can reduce the most impaired position emergence probability of collapsible position 510, improves the security of folding screen 500. The folding structure is particularly suitable for the situation that the folding structure of the foldable portion 510 is in a drop shape, because when the folding structure of the foldable portion 510 is in a drop shape, the outer side of the first folding portion 5101 and the outer side of the second folding portion 5102 can both form the concave space 501, which is beneficial to avoiding the first protruding portion 3151 and improving the stability of the foldable portion 510 in the folding structure.

Meanwhile, since the third region 303 is not provided with the first protruding portion 3151, a space can be formed, when the first surface 12 faces the folding screen 500, the space can avoid the redundancy of the foldable portion 510 in the folded state, which is beneficial to improving the stability of the foldable portion 510 in the folded state, and to make the surface of the foldable portion 510 smoother in the folded state (not easy to generate wrinkles or bulges due to abutting against the folding member 30 in the folded state), and when the first surface 12 faces the rotating shaft mechanism 200, the space can avoid the rotating shaft mechanism 200; moreover, the third region 303 is advantageous in saving material and reducing weight because the first protrusion 3151 is not provided.

Optionally, referring to fig. 20, when the folding assembly 100 is in the unfolded state, along the direction of the first support member 10 toward the second support member 20 (i.e. the first direction a), 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, so that the width of the third region 303 is advantageously increased appropriately, so as to form a larger avoidance space, and better avoid the redundancy of the foldable portion 510 in the folded state or avoid the rotation shaft mechanism 200.

Of course, in other embodiments, the width of the third region 303 may 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 toward the second support 20 when the folding assembly 100 is in the unfolded state.

Optionally, in some embodiments, referring to fig. 22, fig. 22 is a schematic perspective view illustrating a folding assembly 100 in an unfolded state according to other embodiments of the present application. The folding assembly 100 further includes a support film 40, the support film 40 being located on a side of the first protrusion 3151 of the folder 30. The support film 40 is provided with a groove 401, and the first protruding portion 3151 protrudes into the groove 401.

It is understood that, when the number of the first protruding portions 3151 is plural, the number of the grooves 401 may be the same as the number of the first protruding portions 3151, so that the first protruding portions 3151 are disposed in one-to-one correspondence with the grooves 401. The support film 40 has a thin film structure, and may be made of a hard material, for example, a metal material (e.g., stainless steel, etc.), an alloy, etc., but is not limited thereto; the support film may be made of soft material, for example, but not limited to, rubber, silica gel, soft PVC, TPE, TPU, TPR, TPV, and the like.

By the arrangement of the supporting film 40, the folding screen 500 can be supported and protected, the reliability of the folding screen 500 under the action of external force can be improved, and the possibility of damage to the folding portion 510 under the action of external force is further reduced. Meanwhile, the groove 401 formed on the support film 40 can limit the first protruding portion 3151 protruding into the groove, so that the possibility that the first protruding portion 3151 is offset is reduced, larger relative movement between the first protruding portion 3151 and the support film 40 can be limited, stability of the folded piece 30 in the bending or flattening process and stability under action of external force can be improved, stability of the folded piece 30 and the support film 40 can be improved, supporting and protecting effects on the foldable portion 510 can be improved, and the folded portion 510 can be maintained in a bending mode or a flat mode more stably.

Referring to fig. 23, for example, fig. 23 illustrates a partial schematic structure of a terminal device 1000 employing the folding assembly 100 of fig. 22. In terminal device 1000, first face 12 is directed towards spindle mechanism 200, first protrusion 3151 protrudes towards spindle mechanism 200, and support membrane 40 is located between folder 30 and spindle mechanism 200. The support film 40 may be fixed to at least one of the rotation shaft mechanism 200, the first housing 300, and the second housing 400, and a gap may be provided between the support film 40 and the first support 10, and between the support film 40 and the second support 20. When the terminal device 1000 is switched between the folded state and the unfolded state, the groove 401 formed on the supporting film 40 can limit the first protruding portion 3151, so as to limit the larger relative movement between the folded member 30 and the supporting film 40 and between the folded member 30 and the folding screen 500, and facilitate the foldable portion 510 to maintain the folded state or the flat state more stably.

Illustratively, in terminal device 1000, first face 12 projects toward spindle mechanism 200, first projection 3151 projects toward spindle mechanism 200, and support membrane 40 is located between folder 30 and spindle mechanism 200. The support film 40 may be fixed to at least one of the first support 10 and the second support 20, and a gap may be provided between the support film 40 and the rotation shaft mechanism 200. When the terminal device 1000 is switched between the folded state and the unfolded state, the groove 401 formed on the support film 40 can limit the first protruding portion 3151, so that the folding member 30 and the support film 40 can be limited to generate larger relative movement, the stability of the cooperation between the folding member 30 and the support film 40 can be improved, and the foldable portion 510 can be further maintained in a folded state or a flat state more stably.

Illustratively, in terminal device 1000, first face 12 is directed towards folding screen 500 and first protrusion 3151 is protruding towards folding screen 500, and support membrane 40 is located between folding member 30 and folding screen 500. The support film 40 may be fixed to at least one of the first support 10 and the second support 20, or to the folding screen 500. When the terminal device 1000 is switched between the folded state and the unfolded state, the groove 401 formed on the supporting film 40 can limit the first protruding portion 3151, so as to limit the larger relative movement between the folded member 30 and the supporting film 40 and between the folded member 30 and the folding screen 500, and facilitate the foldable portion 510 to maintain the folded state or the flat state more stably.

In other embodiments, the support film 40 may not be provided.

Optionally, in some embodiments, referring to fig. 22, 24 and 25, fig. 24 is a schematic perspective view of a folding assembly 100 in an unfolded state, and fig. 25 is a schematic perspective view of the folding assembly 100 in a folded state when the folding assembly 100 in fig. 24 is mated with a folding screen 500. The elastic body 31 further includes a second protrusion 3152, and the second protrusion 3152 protrudes from the second face 13, that is, the second protrusion 3152 extends to the outside of the second face 13.

It will be appreciated that when the first face 12 is facing the folding screen 500, the first protrusion 3151 protrudes toward the folding screen 500, and the second face 13 protrudes away from the folding screen 500, and the second protrusion 3152 protrudes away from the folding screen 500, as shown in fig. 25, for example. When the second surface 13 faces the folding screen 500, the second protruding portion 3152 protrudes toward the folding screen 500, and when the first surface 12 faces away from the folding screen 500, the first protruding portion 3151 protrudes away from the folding screen 500. That is, the protruding direction of the first protruding portion 3151 is opposite to the protruding direction of the second protruding portion 3152. The second protruding portion 3152 is a part of the elastic body 31, and is elastically deformable.

It is understood that the second protrusion 3152 may be a variety of protruding structures having regular or irregular shapes, such as a bar structure, a column structure, a bulge structure, a cone structure, a sphere structure, etc., but is not limited thereto. The shape of the second protrusion 3152 may be the same as or different from the shape of the first protrusion 3151.

So set up, when folding screen 500 receives external force, for example, when the folding screen 500 collides with pivot mechanism 200 each other, because second protruding portion 3152 is protruding in second face 13, second protruding portion 3152 and first protruding portion 3151 all can be stressed at first, can make elastomer 31 atress at first in order to cushion external force, do benefit to the effect that improves buffering external force, and second protruding portion 3152 plays the effect of spring promptly. And because the protruding direction of the first protruding portion 3151 is opposite to that of the second protruding portion 3152, the elastic body 31 can buffer the external force on the side facing the folding screen 500 and the side facing the rotating shaft mechanism 200, so that the effect of buffering the external force can be further improved, and the possibility of damaging the foldable part 510 of the folding screen 500 is reduced.

Alternatively, referring to fig. 24, the second protruding portion 3152 may be connected to the base 312, where the second protruding portion 3152 protrudes from the surface of the base 312, and the base 312 may provide support for the second protruding portion 3152, and the force applied by the second protruding portion 3152 may also be transferred to the base 312 to further buffer the external force through the base 312.

Optionally, referring to fig. 24, at least one of the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113 may be provided with a second protruding portion 3152, and the second protruding portion 3152 may be transferred to at least one of the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113 when being stressed, so as to further buffer the external force by at least one of the first filling portion 3111, the second filling portion 3112 and the third filling portion 3113. In this case, the first protruding portion 3151 may be provided on at least one of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133.

Of course, the second protruding portion 3152 may be provided on at least one of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133, and the second protruding portion 3152 may be transferred to at least one of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133 when the force is applied, so as to further buffer the external force by at least one of the fourth filling portion 3131, the fifth filling portion 3132, and the sixth filling portion 3133. In this case, at least one of the first filling portion 3111, the second filling portion 3112, and the third filling portion 3113 may be provided with the first protruding portion 3151.

Alternatively, the second protruding portion 3152 may protrude from the outer surface of the first connecting strip 32, and the first protruding portion 3151 may protrude from the outer surface of the second connecting strip 33, as shown in fig. 24.
