[0001] This disclosure relates to the field of electronic equipment technology, and more specifically, to an electronic device and a method for manufacturing a pressure strip. Background Technology

[0002] Currently, electronic devices with flexible displays have appeared on the market. When these devices are folded or unfolded, the display can bend or flatten accordingly. However, during the bending or flattening deformation process, gaps may appear between the flexible display and the frame of the electronic device, making the flexible display susceptible to damage. Summary of the Invention

[0003] In view of this, the present disclosure provides an electronic device and a method for manufacturing a pressure strip.

[0004] One aspect of this disclosure provides an electronic device, comprising: a first body; a connecting device; a second body connected to the first body via the connecting device; a deformable screen including a first portion fixed to the first body, a second portion fixed to the second body, and a deformable portion located between the first body and the second body; the first body including a first frame covering the edge of the first portion; the second body including a second frame covering the edge of the second portion; a deformable pressure strip covering the edge of the deformable portion, having a target gap between the pressure strip and the deformable screen in a first direction; the first direction being perpendicular to the deformable screen; and a filling structure disposed at the target gap, the filling structure including multiple deformable substructures, wherein during the deformation of the deformable screen, the arrangement density of the multiple substructures changes under the action of the pressure strip and the deformable screen, and adjacent substructures remain in contact with each other, so that the filling structure maintains filling of the target gap.

[0005] According to embodiments of this disclosure, a plurality of substructures are disposed on the projection area of ​​the pressure strip along a first direction of the deformable screen.

[0006] According to embodiments of this disclosure, the substructure has a fixed end fixed to the pressure strip and a free end away from the pressure strip.

[0007] According to embodiments of this disclosure, the substructure is a flexible fiber unit, and the multiple flexible fiber units are filamentous, bundled, fluffy, or mesh structures.

[0008] According to an embodiment of this disclosure, the length of the substructure located in the first region is greater than the length of the substructure located in the second region, and the distance from the first region to the middle region of the pressure strip is less than the distance from the second region to the middle region of the pressure strip.

If the first body and the second body are in the second device form via a connecting device, the first part and the second part of the deformable screen are stacked. During the process of the electronic device switching from the first device form to the second device form, the target gap gradually increases, and the degree of deformation of each substructure decreases as the target gap increases.

[0012] According to embodiments of this disclosure, the length of the substructure in its naturally extended state is greater than or equal to the gap width of the target gap during the deformation of the deformable screen.

[0039] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0040] Figure 1 An electronic device diagram is schematically shown according to an embodiment of the present disclosure. Figure 2 A partial enlarged view of the bent region according to an embodiment of the present disclosure is shown schematically. Figure 3 A schematic cross-sectional view of an electronic device according to an embodiment of the present disclosure is shown. Figure 4 Another cross-sectional view of an electronic device according to an embodiment of the present disclosure is shown schematically. Figure 5 A partial schematic diagram of the filling structure according to an embodiment of the present disclosure is shown.

[0041] like Figures 1 to 5 As shown, this embodiment of the present disclosure provides an electronic device, including a first body 1, a connecting device 2, a second body 3, a deformable screen 4, and a retaining strip 5. The second body 3 is connected to the first body 1 via the connecting device 2. The deformable screen 4 is disposed between the first body 1 and the second body 3. The first body 1 includes a first frame 11, which covers the edge of the deformable screen 4 located on one side of the first body 1. The second body 3 includes a second frame 31, which covers the edge of the deformable screen 4 located on one side of the second body 3. The retaining strip 5 is disposed between the first frame 11 and the second frame 31, and is located in the central edge region of the deformable screen 4.

[0042] In this embodiment, the pressure strip 5 is arranged adjacent to the first frame 11 and the second frame 31 along the edge direction of the deformable screen 4, thereby forming a supplementary covering structure in the central area. In this way, when the deformable screen 4 spans the two bodies and there is a deformable area in the middle, the pressure strip 5 can block and protect the central edge area and provide an installation base for filling the gap in the central area.

[0043] Figure 1 Point A in the diagram represents the bending area. This bending area is used to illustrate the relative positional relationship between the pressure strip 5 and the first frame 11 and the second frame 31. Figure 1 As can be seen, the pressure strip 5 is located in the middle between the two side frames, so it can be set to correspond to the middle deformation area of ​​the deformable screen 4, so as to cooperate with the screen movement during the change of the form of the electronic device.

[0044] like Figure 2 As shown, the pressure strip 5 is disposed between the first frame 11 and the second frame 31. The pressure strip 5 extends along the central edge region and connects with the first frame 11 and the second frame 31 in the edge direction. Through this arrangement, the first frame 11, the pressure strip 5, and the second frame 31 can jointly form a continuously distributed edge covering structure corresponding to the central region of the deformable screen 4.

[0045] In this embodiment, the pressure strip 5 can be a deformable component. Thus, when the deformable screen 4 deforms in a folded, unfolded, or transitional state, the pressure strip 5 can adaptively deform with the structural changes of adjacent areas, thereby continuing to correspond to the central edge area. Located between the first frame 11 and the second frame 31, the pressure strip 5 also covers the gap between the two frames. On the one hand, it abuts against the deformable screen 4, reducing the edge warping of the deformable screen 4 during deformation; on the other hand, it helps reduce the possibility of foreign particles entering through this area.

[0046] like Figure 3 As shown, the connecting device 2 is located between the first body 1 and the second body 3. The deformable screen 4 includes a first part 41 and a second part 42. The first part 41 is fixed to the first body 1, and the second part 42 is fixed to the second body 3. The first frame 11 covers the edge of the first part 41, and the second frame 31 covers the edge of the second part 42. A pressure strip 5 is provided corresponding to the middle area between the first part 41 and the second part 42. A target gap 6 is provided between the pressure strip 5 and the deformable screen 4. The first direction 7 is perpendicular to the deformable screen 4.

[0047] In this structure, the target gap 6 is located between the pressure strip 5 and the deformable screen 4, and extends along the central region. Since the first direction 7 points perpendicular to the deformable screen 4, the target gap 6 can be understood as the space between the pressure strip 5 and the deformable screen 4 in the thickness direction. When the electronic device switches between different forms, the position of the central region relative to the pressure strip 5 will change, and the gap width of the target gap 6 will also change accordingly.

[0048] Furthermore, the pressure strip 5 covers the edge of the central area, and the first frame 11, the pressure strip 5, and the second frame 31 together define the edge protection range of the corresponding central area. In this way, when the central area of ​​the deformable screen 4 deforms, the pressure strip 5 can not only cooperate with the edge coverage, but also cooperate with the filling structure to occupy the gap at the location of the target gap 6.

[0049] like Figure 4 As shown, the deformable screen 4 includes a first portion 41, a second portion 42, and a deformable portion 43 located between the first portion 41 and the second portion 42. A filling structure 51 is located in the corresponding area of ​​the deformable portion 43 and is disposed between the pressure strip 5 and the deformable screen 4. The deformable portion 43 corresponds to the central region between the first body 1 and the second body 3, which undergoes bending deformation during changes in the form of the electronic device.

[0050] In this embodiment, the filling structure 51 is provided corresponding to the deformable portion 43. Thus, when the target gap 6 formed between the pressure strip 5 and the deformable screen 4 is located in the corresponding area of ​​the deformable portion 43, the filling structure 51 can be positioned within the target gap 6 and fill it. Since the deformable portion 43 changes position during the transformation of the electronic device, the filling structure 51 can also be adjusted accordingly to match the area of ​​the pressure strip 5.

[0051] Furthermore, the filling structure 51 does not form discrete contacts only at local locations, but is continuously provided along the edge region corresponding to the deformed portion 43. In this way, the filling structure 51 can form a continuous gap occupancy portion in the central region, so as to continue to maintain the filling state of the target gap 6 when the deformed portion 43 deforms.

[0052] like Figure 5 As shown, the filling structure 51 includes multiple substructures 511. These substructures 511 are disposed between the pressure strip 5 and the deformable screen 4, and are arranged corresponding to the central region between the first part 41 and the second part 42. The multiple substructures 511 together form a filling layer for the target gap 6.

[0053] In one embodiment, the filling structure 51 can be a porous discrete structure formed by the assembly and fixation of multiple substructures 511. The multiple substructures 511 have air gaps, and the whole exhibits high porosity and compressibility. During the process of being subjected to force, the multiple substructures 511 can be rearranged and changed.

[0054] Understandably, under the action of external force, the deformation of the filling structure 51 mainly comes from the bending, sliding and rearrangement of each substructure 511. Under the action of external force and after the removal of external force, the bending, sliding and rearrangement of each substructure 511 are not necessarily reversible. The arrangement of each substructure 511 before the application of external force and the arrangement of each substructure 511 after the application and removal of external force can be different.

[0055] In this embodiment, the multiple substructures 511 are deformable structures. When the shape of the electronic device changes, the gap width of the target gap 6 changes, and the multiple substructures 511 can deform accordingly and adjust their relative arrangement. When the target gap 6 decreases, the multiple substructures 511 can tend to be arranged more closely; when the target gap 6 increases, the multiple substructures 511 can spring back, expand, or adjust their relative positions.

[0056] It should be noted that during the change of arrangement of multiple substructures 511, adjacent substructures 511 maintain mutual contact, such as abutting, touching, overlapping, or staggered contact. In this way, even when the target gap 6 is large, adjacent substructures 511 can still maintain a continuous abutment relationship, and it is difficult for a void channel to form inside the filling structure 51 that runs through the thickness direction of the target gap 6. Therefore, the filling structure 51 continuously fills the target gap 6 as it changes. Thus, when the pressure strip 5 and the filling structure 51 cooperate, the central region not only has an edge covering structure but also a gap-occupying structure that can continuously maintain a filled state as the target gap 6 changes. This makes it difficult for particulate matter located in the central region to enter the interior along the target gap 6, which is beneficial for protecting the deformable portion 43 of the deformable screen 4.

[0057] Figure 6 A schematic cross-sectional view of the assembly of the pressure strip and filling structure according to an embodiment of the present disclosure is shown.

[0058] like Figure 6 As shown, the filling structure 51 is disposed on the side of the pressure strip 5 facing the deformable screen 4, and the two can be combined to form a gap filling assembly for the central region. The pressure strip 5 is located above the connecting device 2, and the filling structure 51 is located between the pressure strip 5 and the connecting device 2 and extends towards the side where the deformable screen 4 is located. With this arrangement, the filling structure 51 can be disposed together with the pressure strip 5 in the central region of the electronic device.

[0059] In this embodiment, the filling structure 51 can be supported by the pressure strip 5. Thus, when the pressure strip 5 covers the edge of the deformable portion 43, the filling structure 51 can be simultaneously positioned in the area where the target gap 6 is located. When the form of the electronic device changes, the pressure strip 5 adapts to the structural changes in the central region, and the filling structure 51 can also maintain its filling state within the target gap 6.

[0060] Figure 7 The diagram illustrates an assembly of the pressure strip, filling structure, and related components according to an embodiment of the present disclosure.

[0061] like Figure 7 As shown, the pressure strip 5 and the filling structure 51 are located between the first frame 11, the second frame 31, and the connecting device 2. During assembly, the pressure strip 5 and the filling structure 51 are respectively positioned in the middle region between the first frame 11 and the second frame 31, and cooperate with the region where the connecting device 2 is located. Thus, the pressure strip 5 can cover the edge of the deformable portion 43 between the two frames, and the filling structure 51 can be located at the target gap 6 between the pressure strip 5 and the deformable screen 4.

[0062] Furthermore, Figure 7The structure shown indicates that the pressure strip 5 and the filling structure 51 can be arranged as a central component above the connecting device 2, located between the first frame 11 and the second frame 31. Thus, after the electronic device is assembled, the first frame 11, the pressure strip 5, and the second frame 31 are sequentially distributed along the edge direction of the deformable screen 4, while the filling structure 51 is correspondingly positioned on the side of the pressure strip 5 facing the deformable screen 4, thereby forming a filling protective structure in the central region that connects with the two side frames.

[0063] In the above structure, the filling structure 51 can both cooperate with the pressure strip 5 to cover the edge area of ​​the deformed part 43, and continuously occupy the target gap 6 through the arrangement changes among the multiple substructures 511 when the target gap 6 changes. Therefore, combined with Figures 1 to 7 It is understood that by setting the pressure strip 5 and the filling structure 51 located at the target gap 6, the electronic device makes the arrangement of multiple substructures 511 between the pressure strip 5 and the deformable screen 4 during the deformation of the deformable screen 4, and keeps them in contact with each other between adjacent substructures 511, so that the filling structure 51 keeps filling the target gap 6.

[0064] In some embodiments, the first direction 7 is perpendicular to the deformable screen 4. A single substructure 511 may extend in the first direction 7, and / or, a single substructure 511 may extend in the opposite direction to the first direction 7. The extension orientation of the substructure 511 may be configured to cooperate with the mounting position of the infill structure 51.

[0065] In some embodiments, the filling structure 51 is disposed on the side of the pressure strip 5 facing the deformable screen 4. In this case, multiple substructures 511 extend from the pressure strip 5 towards the deformable screen 4, and each substructure 511 can extend in a first direction 7, thereby entering the target gap 6 between the pressure strip 5 and the deformable screen 4. When the electronic device changes shape, the multiple substructures 511 can bend, compress, or spring back within the target gap 6, maintaining their filling of the target gap 6.

[0066] In some embodiments, the filling structure 51 is disposed at the deformable portion 43 of the deformable screen 4, and is located on the side of the deformable portion 43 facing the pressure strip 5. At this time, multiple substructures 511 extend from the deformable portion 43 towards the pressure strip 5, and a single substructure 511 can extend in the opposite direction of the first direction 7, thereby entering the target gap 6. As the deformable portion 43 bends or unfolds, the multiple substructures 511 can deform synchronously with the deformable portion 43 and form a filler within the target gap 6.

[0067] In other embodiments, the filling structure 51 can be simultaneously provided at both the pressure strip 5 and the deformable portion 43. That is, a portion of the substructure 511 is provided on the pressure strip 5, and another portion of the substructure 511 is provided at the deformable portion 43. The substructure 511 extending from the pressure strip 5 can extend in a first direction 7, and the substructure 511 extending from the deformable portion 43 can extend in the opposite direction of the first direction 7. The two portions of the substructure 511 are distributed facing each other within the target gap 6 and can come into contact with each other, abut, overlap, or stagger, thereby jointly forming a filling structure for the target gap 6.

[0068] Furthermore, when the filling structure 51 is only provided on the pressure strip 5, the substructure 511 can extend from one side of the pressure strip 5 towards the deformed portion 43; when the filling structure 51 is only provided at the deformed portion 43, the substructure 511 can extend from one side of the deformed portion 43 towards the pressure strip 5; when the filling structure 51 is provided at both the pressure strip 5 and the deformed portion 43, the substructures 511 from both sides can form opposing contact or staggered fit within the target gap 6. Through the above settings, the extension direction of the substructure 511 can not only adapt to different installation positions, but also help maintain a continuous filling state during the change of the target gap 6.

[0069] It should be noted that the extension of a single substructure 511 in the first direction 7 or in the opposite direction of the first direction 7 is used to characterize the main extension orientation of the single substructure 511, and does not exclude the possibility that the single substructure 511 will undergo elastic bending, local deflection or follow-up deformation under stress. As long as the single substructure 511 as a whole has an extension trend along the first direction 7 or in the opposite direction of the first direction 7, the above-mentioned setting method can be adopted.

[0070] In some embodiments, a plurality of substructures 511 are disposed on the deformable screen 4 along a first direction 7 within the projection area of ​​the pressure strip 5. The first direction 7 is perpendicular to the deformable screen 4. In other words, after the pressure strip 5 is projected toward the deformable screen 4 along the first direction 7, the area on the deformable screen 4 corresponding to the pressure strip 5 constitutes the projection area, and the plurality of substructures 511 are disposed within this projection area.

[0071] It is understood that the aforementioned projection area is located on the deformable screen 4 and corresponds to the corresponding range of the pressure strip 5 in the first direction 7. After multiple substructures 511 are set in this projection area, the multiple substructures 511 can correspond to the distribution of the target gap 6 between the pressure strip 5 and the deformable screen 4, thereby filling the target gap 6 in the corresponding area of ​​the pressure strip 5.

[0072] In some embodiments, a plurality of substructures 511 are disposed within the aforementioned projection area on the deformable screen 4. In this way, the distribution range of the plurality of substructures 511 matches the corresponding range of the pressure strip 5 in the first direction 7, which facilitates the formation of continuous gap-filling portions by the plurality of substructures 511 within the area corresponding to the pressure strip 5.

[0073] Furthermore, regardless of whether the filling structure 51 is located on one side of the pressure strip 5 or on one side of the deformable portion 43 of the deformable screen 4, multiple substructures 511 can be located within the projection area of ​​the pressure strip 5 along the first direction 7 of the deformable screen 4. When multiple substructures 511 are provided on both one side of the pressure strip 5 and one side of the deformable portion 43, the multiple substructures 511 in both parts can also be correspondingly located within the aforementioned projection area, so that the multiple substructures 511 fill the target gap 6 within the corresponding range of the pressure strip 5.

[0074] Figure 8 The diagram illustrates the interaction between the substructure and the pressure strip according to an embodiment of the present disclosure.

[0075] like Figure 8 As shown, the substructure 511 has a fixed end 5111 fixed to the pressure strip 5 and a free end 5112 away from the pressure strip 5. In this embodiment, the substructure 511 is disposed on the pressure strip 5. One end of the substructure 511 is connected to the pressure strip 5, forming the fixed end 5111; the other end of the substructure 511 extends away from the pressure strip 5, forming the free end 5112. Thus, the substructure 511 can be disposed on the pressure strip 5 with the fixed end 5111 as the connection position, and extend outward through the free end 5112.

[0076] Understandably, the fixed end 5111 is used to connect and position the substructure 511 and the pressure strip 5, ensuring that the substructure 511 remains in its corresponding position on the pressure strip 5. The free end 5112 is used to deflect, bend, or elastically deform when the target gap 6 changes, and to form contact, abutment, overlap, or staggered fit with adjacent substructures 511. Thus, during changes in the form of the electronic device, the substructure 511, while connected to the pressure strip 5 at the fixed end 5111, can adapt to changes in the target gap 6 through the deformation of the free end 5112.

[0077] In some embodiments, multiple substructures 511 are connected to the pressure strip 5 via their respective fixed ends 5111 and extend away from the pressure strip 5 from their respective free ends 5112. In this way, the multiple substructures 511 can extend from the pressure strip 5 into the target gap 6 and form a filling structure within the target gap 6.

[0078] Furthermore, since the substructure 511 has a fixed end 5111 and a free end 5112, the substructure 511 can deform relative to the fixed end 5111 under pressure, while the free end 5112 can deflect or displace accordingly. Thus, when the target gap 6 decreases, the multiple substructures 511 can achieve a more compact arrangement by the free end 5112 making way; when the target gap 6 increases, the free end 5112 can spring back or expand to continue to correspond to the distribution of the target gap 6.

[0079] In some embodiments, the free ends 5112 of adjacent substructures 511 can remain in contact with each other, abutting, overlapping, or staggered. In this way, even if the relative positions of multiple substructures 511 are adjusted during deformation, a continuous filling state can still be maintained through the cooperation between the free ends 5112.

[0080] It should be noted that, Figure 8 The diagram illustrates the arrangement of a fixed end 5111 and a free end 5112 using a single substructure 511. Multiple substructures 511 can be arranged on the pressure strip 5 using the same or similar connection methods. As long as the substructure 511 has a fixed end 5111 connected to the pressure strip 5 and a free end 5112 extending away from the pressure strip 5, the above arrangement method can be used.

[0081] Figure 9 Various schematic structures of substructures according to embodiments of the present disclosure are illustrated.

[0082] like Figure 9 As shown, substructure 511 is a flexible fiber unit, and multiple flexible fiber units are disposed on the pressure strip 5. The flexible fiber unit has the characteristics of being bendable and deflectable, so that it can deform with the change of the target gap 6 when the shape of the electronic device changes, so as to fill the target gap 6.

[0083] In some embodiments, the multiple flexible fiber units can be filamentous structures. With this arrangement, individual substructures 511 can be elongated filaments extending outward from the pressure strip 5. The multiple filamentous substructures 511 are capable of bending under pressure and deflecting or springing back when the gap changes, thereby adapting to changes in the target gap 6.

[0084] In some embodiments, the multiple flexible fiber units can be a bundled structure. With this arrangement, a substructure 511 may include multiple adjacent flexible fibers to form a bundled distribution. The bundled structure can provide overall support while maintaining flexibility, allowing the multiple substructures 511 to fill the target gap 6.

[0085] In some embodiments, the multiple flexible fiber units can be a pile-like structure. With this arrangement, the multiple substructures 511 can be densely distributed on the pressure strip 5 and arranged in a pile-like pattern. In this way, a relatively continuous filling area can be formed between the multiple substructures 511 so that the filling state can be maintained by mutual contact and deformation when the target gap 6 changes.

[0086] In some embodiments, the multiple flexible fiber units can be a mesh structure. With this arrangement, the multiple substructures 511 interweave or connect to form a mesh arrangement. In this way, the multiple substructures 511 can form a flexible structure with interconnected relationships on the pressure strip 5, and adapt to changes in the central region within the target gap 6 through overall deformation.

[0087] Understandable, Figure 9 The filamentous structure, bundled structure, fluffy structure, and mesh structure shown are all optional structural forms of flexible fiber units. In electronic devices, multiple substructures 511 can be configured using one of these structural forms; in some embodiments, a suitable flexible fiber structure can also be selected according to the arrangement needs of the central region, so that multiple substructures 511 fill the target gap 6 in the area corresponding to the pressure strip 5.

[0088] The following is combined Figures 10 to 12 The structure of the pressure strip 5 will be further explained.

[0089] Figure 10 The diagram schematically illustrates a cross-sectional view of the clamping strip when the electronic device according to an embodiment of the present disclosure is in a bent state. Figure 11 A cross-sectional view of the pressure strip according to an embodiment of the present disclosure is shown schematically. Figure 12 Another schematic diagram of a pressure strip according to an embodiment of the present disclosure is shown.

[0090] like Figures 10 to 12 As shown, the pressure strip 5 can be a strip-shaped member extending along its own length. The pressure strip 5 has a flexible body structure so that it can bend and deform to correspond to the shape changes of the central region of the electronic device. When the electronic device is in a bent state, at least the central region of the pressure strip 5 can form a bent section, thereby adapting to the bending profile of the central region.

[0091] In some embodiments, the pressure strip 5 is generally elongated, and the pressure strip 5 can extend continuously in the length direction, and a mounting part suitable for installing the filling structure 51 is formed in its central region.

[0092] like Figure 11 and Figure 12As shown, the filling structure 51 is disposed on the pressure strip 5 and distributed along the length direction of the pressure strip 5. Multiple substructures 511 can be arranged in the extension direction of the pressure strip 5, so that the filling structure 51 forms a continuous distribution structure on the pressure strip 5.

[0093] Furthermore, such as Figure 11 and Figure 12 As shown, a connecting wall 52 is also provided on the pressure strip 5. The connecting wall 52 is provided on the pressure strip 5 and connected to the pressure strip 5. The filling structure 51 and the connecting wall 52 can be respectively provided on both sides of the pressure strip 5. With this arrangement, the pressure strip 5 can both support the filling structure 51 and be connected and assembled with related structures through the connecting wall 52.

[0094] In some embodiments, the connecting wall 52 is located in the middle of the pressure strip 5. In this way, the connecting wall 52 can provide a connection point for the pressure strip 5 and facilitate the installation of the pressure strip 5 in the middle region of the electronic device.

[0095] like Figure 10 As shown, when the electronic device is in a bent state, the pressure strip 5 can form a curved shape that adapts to the central region, and the filling structure 51 is distributed along with the bending of the pressure strip 5. Thus, the pressure strip 5 can serve as a support for the filling structure 51, allowing the filling structure 51 to be positioned in the central region of the electronic device along with the pressure strip 5.

[0096] Figure 13 The diagram illustrates the length distribution of different regional substructures according to embodiments of the present disclosure.

[0097] like Figure 13 As shown, the pressure strip 5 can be divided into a first region and a second region. The first region is closer to the middle region of the pressure strip 5, and the second region is farther from the middle region of the pressure strip 5. The length of the substructure 511 located in the first region is greater than the length of the substructure 511 located in the second region. In this embodiment, the length of the substructure 511 can gradually decrease as it extends from the middle region to both sides along the length direction of the pressure strip 5. That is, the substructure 511 located closer to the middle region of the pressure strip 5 is relatively longer, while the substructure 511 located farther from the middle region of the pressure strip 5 is relatively shorter. Through the above arrangement, the substructures 511 at different positions of the pressure strip 5 can form a differentiated length distribution, thereby better adapting to the structural change requirements of the middle region and the regions on both sides of the pressure strip 5.

[0098] In some embodiments, the first region may be located in the central area corresponding to the connecting wall 52, and the second region may be located on both sides of the first region. In this way, the substructure 511 near the center of the pressure strip 5 is longer, while the substructure 511 further away from the center is shorter, so as to form an arrangement structure that matches the central contour of the pressure strip 5.

[0099] Figure 14 A schematic diagram illustrating the density distribution of different regional substructures according to embodiments of the present disclosure is shown.

[0100] like Figure 14 As shown, the pressure strip 5 can be divided into a third region and a fourth region. The third region is closer to the middle region of the pressure strip 5, while the fourth region is farther from the middle region of the pressure strip 5. The density between the substructures 511 in the third region is greater than the density between the substructures 511 in the fourth region.

[0101] In this embodiment, the substructures 511 located near the middle area of ​​the pressure strip 5 are arranged more densely, while those located further away are arranged relatively sparsely. This arrangement allows for a more continuous filling structure to be formed in the corresponding position of the middle area of ​​the pressure strip 5, thereby improving the continuity and stability of the filling in this area. Specifically, the middle is typically the main deformation zone, where inconsistent local opening, compression, and rebound are more likely to occur during shape changes. Higher density means more substructures per unit length, making it easier for them to maintain continuous overlap or contact. Therefore, even if individual substructures deflect, collapse, or have insufficient rebound, gaps are less likely to appear overall. Furthermore, a denser middle section results in more contact points and more dispersed stress. This means that when deformation occurs in the middle, it is less likely that only a few longer substructures will bear the load, resulting in a more uniform overall structure.

[0102] In some embodiments, the third region is located in the middle of the pressure strip 5, and the fourth region is located on both sides of the third region. In this way, the position near the middle region of the pressure strip 5 can have a higher arrangement density of substructures 511, so as to maintain a relatively continuous filling state even when the shape of the middle region changes significantly.

[0103] In this embodiment, the electronic device includes at least a first device form and a second device form. When the first body 1 and the second body 3 are in the first device form through the connecting device 2, the first part 41 and the second part 42 of the deformable screen 4 belong to the same surface; when the first body 1 and the second body 3 are in the second device form through the connecting device 2, the first part 41 and the second part 42 of the deformable screen 4 are stacked.

[0104] In some embodiments, the first device form can be an unfolded state of the electronic device, and the second device form can be a folded state of the electronic device. In this case, in the unfolded state, the first part 41 and the second part 42 of the deformable screen 4 together form a continuous display surface; in the folded state, the first part 41 and the second part 42 of the deformable screen 4 are close to each other and stacked, and the deformable part 43 is located in the transition area between the two.

[0105] During the process of switching the electronic device from the first device form to the second device form, the target gap 6 gradually increases, and at least some of the free ends 5112 of the substructures 511 maintain elastic contact with the deformable part 43. That is to say, as the form of the electronic device changes, each substructure 511 can adapt to the change in the relative position between the deformable part 43 and the pressure strip 5 through the elastic deformation of the free ends 5112.

[0106] In some embodiments, in the first device configuration, each substructure 511 maintains elastic contact with the deformable portion 43. Thus, each substructure 511 can be distributed correspondingly to the deformable portion 43 in the first device configuration.

[0107] Furthermore, after the electronic device switches to the second device configuration, at least a portion of the substructure 511 located in the first region remains in elastic contact with the deformable portion 43. Correspondingly, the portion of the substructure 511 located away from the first region can separate from the deformable portion 43 as the target gap 6 increases. With this arrangement, the substructure 511 near the middle region of the pressure strip 5 can still maintain elastic contact with the deformable portion 43 in the second device configuration, thereby helping to maintain the filling continuity and contact stability at the corresponding position in the middle region.

[0108] In this embodiment, the electronic device includes at least a first device form and a second device form. When the first body 1 and the second body 3 are in the first device form through the connecting device 2, the first part 41 and the second part 42 of the deformable screen 4 belong to the same surface; when the first body 1 and the second body 3 are in the second device form through the connecting device 2, the first part 41 and the second part 42 of the deformable screen 4 are stacked.

[0109] In some implementations, the first device configuration can be an unfolded state of the electronic device, and the second device configuration can be a folded state of the electronic device. In this case, during the transition of the electronic device from the unfolded state to the folded state, the target gap 6 gradually increases.

[0110] As the target gap 6 gradually increases, the degree of deformation of each substructure 511 gradually decreases. That is to say, in the first device form, the degree of bending, compression or deflection of each substructure 511 caused by the extrusion of the deformed part 43 is relatively large; as the electronic device switches to the second device form, the extrusion of the substructure 511 decreases, and correspondingly, the degree of deformation of each substructure 511 gradually decreases.

[0111] With the above settings, each substructure 511 can adaptively adjust its deformation state as the shape of the electronic device changes, thereby adapting to the changes in the target gap 6.

[0112] In this embodiment, the length of the substructure 511 in its naturally extended state is greater than or equal to the gap width of the target gap 6 during the deformation of the deformable screen 4. That is, when not compressed or elastically deformed, the length of the substructure 511 along its own extension direction is not less than the gap width of the target gap 6 during the deformation process.

[0113] With the above settings, after the substructure 511 is placed in the target gap 6, it can adapt to the deformable part 43 through its own elastic deformation, which is conducive to maintaining continuous filling of the corresponding area of ​​the substructure 511 during the deformation of the deformable screen 4.

[0114] In some embodiments, when the substructure 511 is in its naturally extended state, its free end 5112 can extend toward the deformable portion 43 so that the substructure 511 still has a structural basis for contacting the deformable portion 43 when the target gap 6 changes.

[0115] Figure 15 A flowchart illustrating a method for manufacturing a pressure strip according to an embodiment of the present disclosure is shown schematically. Figure 16 Another flowchart illustrating a method for manufacturing a pressure strip according to an embodiment of the present disclosure is shown.

[0116] like Figure 15 As shown, the manufacturing method of the pressure strip may include at least operations S1510 to S1530.

[0117] In operation S1510, the preform is positioned within the mold. The preform includes an infill structure, which comprises multiple substructures. (Reference) Figure 16 As shown, in this operation, the filling structure 51 can be pre-positioned within the mold 8 as a preform. The filling structure 51 can be a pre-formed brush-like structure with multiple substructures 511 on it. By pre-positioning the filling structure 51 within the mold 8, a positional basis can be provided for the subsequent injection molding of the molded part.

[0118] In operation S1520, injection molding is performed on the mold to form a deformable molded part with a fixed filling structure. (Reference) Figure 16 As shown, after the filling structure 51 is positioned within the mold 8, a molded part 9 can be formed in at least a portion of the filling structure 51 by in-mold injection molding, thereby fixing the filling structure 51 onto the molded part 9. The molded part 9 can be a deformable structure so that a deformable pressure strip 5 can be subsequently formed.

[0119] In operation S1530, the formed part is punched to obtain a deformable pressure strip. (Reference) Figure 16As shown, after forming the molded part 9, the molded part 9 can be punched along a preset contour (such as the dotted line part) to remove the connecting material and form the shape of the pressure strip 5. The pressure strip 5 obtained after punching is provided with a filling structure 51 and can form a connecting wall 52 as described in the relevant embodiments above.

[0120] The pressure strip is used to assemble an electronic device having a first body, a second body, and a deformable screen. The deformable pressure strip is used to cover the edge of the deformable part of the deformable screen. There is a target gap between the pressure strip and the deformable screen in a first direction. The first direction is perpendicular to the deformable screen. The filling structure is located at the target gap. During the deformation of the deformable screen, the arrangement density between multiple substructures changes under the action between the pressure strip and the deformable screen, and adjacent substructures remain in contact with each other so that the filling structure keeps filling the target gap.

[0121] In operation S1510, the filling structure 51, which serves as a preform, can be positioned within the mold 8. The filling structure 51 can be a pre-made brush-like structure containing multiple substructures 511. Pre-positioning the filling structure 51 facilitates a stable fit between the filling structure 51 and the molded part 9 during subsequent injection molding.

[0122] In some implementations, reference Figure 16 As shown, after the pressure strip 5 is formed, it can be installed at a corresponding position on the connecting device 2. For example, the connecting wall 52 on the pressure strip 5 can be connected to a portion 21 on the connecting device 2. The portion 21 can be, for example, a side axial surface on the connecting device 2. In some embodiments, the connecting wall 52 and the portion 21 can be connected by laser welding.
