Flexible screen assembly and electronic device

Abstract

The application relates to a flexible screen assembly and an electronic device. The flexible screen assembly comprises a flexible display screen, a bonding layer and a support assembly. The bonding layer is located on a non-display surface of the flexible display screen. The support assembly is located on a surface of the bonding layer away from the flexible screen assembly and is connected to the flexible screen through the bonding layer. The support assembly comprises a plurality of support pieces. Adjacent two support pieces are at least partially connected in structure. The adjacent two support pieces are configured to be capable of extruding each other when the flexible display screen slides, so as to provide a tensile stress to the flexible display screen in a corresponding area of the support pieces. In the above manner, the adjacent two support pieces can extrude each other to provide a tensile stress in a horizontal direction to the flexible display screen in the corresponding area, so that the flexible display screen is prevented from being arched or wrinkled in the process of folding the electronic device, and the appearance performance of the electronic device is improved.

Description

Technical Field

[0001] This application relates to the field of electronic device technology, specifically to a flexible screen component and an electronic device. Background Technology

[0002] With the development of smart terminal devices, the form of screens, as interactive interfaces, is becoming increasingly diverse. Stretchable flexible screens offer users more diverse options for their display needs.

[0003] When using electronic devices, the surface of the flexible screen near the bending area is prone to arching during the retraction process. This not only makes it difficult to continue the retraction process but also affects the appearance of the electronic device. Summary of the Invention

[0004] This application provides a flexible screen assembly and an electronic device to solve the problem of easy arching on the surface of the flexible screen assembly of the electronic device.

[0005] This application provides a flexible screen assembly, including:

[0006] Flexible display screen;

[0007] An adhesive layer is located on the non-display surface of the flexible display screen; and

[0008] A support assembly is located on the surface of the adhesive layer opposite to the flexible screen assembly and is connected to the flexible screen through the adhesive layer; the support assembly includes a plurality of support members, and at least part of the structure of two adjacent support members is in contact.

[0009] Wherein, two adjacent support members are configured to press against each other when the flexible display slides, so as to provide tensile tension to the flexible display in the area corresponding to the support member.

[0010] The flexible screen assembly provided in this application embodiment connects two adjacent support members in the support assembly, so that when the flexible display slides (specifically, when the first carrier and the second carrier switch to the retracted state), the two adjacent support members can squeeze each other to provide horizontal tensile tension for the flexible display in the corresponding area, thereby preventing the flexible display from arching or wrinkling during the retraction of the electronic device and improving the appearance of the electronic device.

[0038] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 This is a three-dimensional schematic diagram of the electronic device in its folded state according to an embodiment of this application. Figure 2 yes Figure 1 The diagram shows a three-dimensional representation of an electronic device in its unfolded state. This application provides an electronic device 100. Specifically, the electronic device 100 can be any of various types of computer system devices that are mobile or portable and perform wireless communication. Figure 1 (Only one form is shown as an example). Specifically, electronic device 100 can be a mobile phone or smartphone (e.g., an iPhone™-based phone, an Android™-based phone), a portable gaming device (e.g., a Nintendo DS™, PlayStation Portable™, Gameboy Advance™, iPhone™), a laptop computer, a PDA, a portable internet device, a music player, and a data storage device, other handheld devices, and such as headphones. Electronic device 100 can also be other wearable devices that require charging (e.g., head-mounted devices (HMDs) such as electronic bracelets, electronic necklaces, electronic devices, or smartwatches).

[0040] Electronic device 100 may also be any one of a plurality of electronic devices, including but not limited to cellular phones, smartphones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transport instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbooks, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Image Experts Group (MPEG-1 or MPEG-2) audio layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0041] In some cases, electronic device 100 can perform multiple functions (e.g., playing music, displaying video, storing pictures, and receiving and sending telephone calls). If desired, electronic device 100 can be such as a cellular phone, media player, other handheld device, wristwatch, pendant device, handset device, or other compact portable device.

[0042] It should be noted that the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] Please refer to the above as well. Figures 3 to 5 , Figure 3 yes Figure 2 An exploded schematic diagram of the electronic device shown. Figure 4 yes Figure 3 The diagram shows an explosion of the electronic device from another angle. Figure 5 yes Figure 4The diagram shows an exploded view of the first and second carriers in the electronic device. This application provides an electronic device 100, which may include a first carrier 10 (i.e., a fixed frame), a second carrier 20 (i.e., a movable frame), and a flexible screen assembly 30. The first carrier 10 is movable relative to the second carrier 20, allowing them to switch between a retracted state and an unfolded state. The flexible screen assembly 30 includes a first end 301 and a second end 302 facing away from each other. The first end 301 is fixed to the first carrier 10. The second carrier 20 has a curved surface structure 201, and the second end 302 is wound around the curved surface structure 201 and at least partially housed within the second carrier 20. When the first carrier 10 and the second carrier 20 are switched to the retracted state, the second end 302 part of the structure can extend into the second carrier 20 along the curved surface structure 201 to realize the retraction of the flexible screen assembly 30; when the first carrier 10 and the second carrier 20 are switched to the unfolded state, the second end 302 part of the structure can unfold from the second carrier 20 along the curved surface structure 201 to realize the unfolding of the flexible screen assembly 30.

[0044] The electronic device 100 may also include a drive mechanism (not shown), which is connected to the first carrier 10 and the second carrier 20 respectively. Under the drive of the drive mechanism, the first carrier 10 and the second carrier 20 move closer to each other to switch to a retracted state, or move further apart to switch to an unfolded state.

[0045] Please refer to Figure 6 and Figure 7 , Figure 6 yes Figure 5 The diagram shown is an exploded view of the first carrier. Figure 7 yes Figure 6 The diagram shows an exploded view of the first carrier from another angle. In this embodiment, the first carrier 10 may include a first outer shell 11 and a first inner shell 12 connected to the first outer shell 11. The first outer shell 11 and the first inner shell 12 enclose a first accommodating space 110 for accommodating and fixing structures such as batteries and circuit boards.

[0046] Specifically, the first outer casing 11 may include a middle plate 111 and two first side plates 112, wherein the two first side plates 112 are spaced apart and located on opposite sides of the middle plate 111. The middle plate 111 includes a first surface 1111 and a second surface 1112 arranged opposite to each other. The first surface 1111 may be recessed to form a plurality of first fixing grooves 11111, which can be used to fix structures such as batteries and circuit boards. The second surface 1112 may be recessed to form a plurality of second fixing grooves 11121, which can be used to fix a drive mechanism.

[0047] The first surface 1111 of the middle plate 111 can protrude to form a boss 11112. The boss 11112 can be used to support the first inner shell 12, so that the first inner shell 12 and the middle plate 111 are spaced apart, thereby increasing the volume of the first accommodating space 110 and improving the space utilization of the first carrier 10. Specifically, the boss 11112 can be provided with a plurality of first fixing holes 11113. The boss 11112 is connected to the first outer shell 11 by fasteners such as screws passing through the first inner shell 12 and the first fixing holes 11113.

[0048] Furthermore, the boss 11112 is arranged adjacent to the first side plate 112. On the one hand, it can be used to support the first inner shell 12 and reduce the impact of the boss 11112 on the layout of the first accommodating space 110. On the other hand, the second surface 1112 of the middle plate 111 can be recessed to form a groove 11122 corresponding to the position of the boss 11112, so that the first carrier 10 can slide in the groove 11122, so as to make full use of the space of the middle plate 111, thereby making the structure of the first carrier 10 compact.

[0049] The first inner shell 12 may be provided with a second fixing hole 120 corresponding to the first fixing hole 11113. The fixing component, such as a screw, passes through the second fixing hole 120 and the corresponding first fixing hole 11113 in sequence to realize the connection between the first inner shell 12 and the first outer shell 11.

[0050] The first inner shell 12 includes a fixing region 121 and a mating region 122. The fixing region 121 is located at the end of the first inner shell 12 away from the second carrier 20 and is used to fix the first end 301 of the flexible screen assembly 30. The mating region 122 is located at the end of the first inner shell 12 close to the second carrier 20 and is used to mate with the second carrier 20.

[0051] Furthermore, multiple first limiting strips 1221 are formed side-by-side on the protrusions of the mating area 122, and two adjacent first limiting strips 1221 form a first limiting groove 1222. The first limiting groove 1222 can hold and accommodate a portion of the structure of the second carrier 20, allowing the portion of the second carrier 20 to move along the first limiting groove 1222, thereby limiting the direction of movement of the second carrier 20 relative to the first carrier 10 and ensuring the stability of the movement of the second carrier 20 and the first carrier 10.

[0052] Please refer to the above as well. Figure 8 and Figure 9 , Figure 8 yes Figure 5 The diagram shown is an exploded view of the second carrier. Figure 9 yes Figure 8The diagram shows a perspective view of the main housing of the second carrier from another angle. In this embodiment, the second carrier 20 may include a second outer shell 21 and a second inner shell 22 connected to the second outer shell 21. The second inner shell 22 and the second outer shell 21 may enclose a second accommodating space 220 that accommodates the second end 302 of the flexible screen assembly 30.

[0053] Specifically, the second outer shell 21 includes a base plate 211, two second side plates 212, and a first connecting plate 213. The two second side plates 212 are spaced apart and located on the two sides of the base plate 211, with the width of each side plate 212 being significantly smaller than the width of the base plate 211, and the side plates 212 located at the ends of the base plate 211 furthest from the first carrier 10. The first connecting plate 213 connects the two second side plates 212 and is connected to the edge of the base plate 211. The first connecting plate 213, the second side plates 212, and the base plate 211 enclose a protective space 2130, which can accommodate a portion of the second inner shell 22.

[0054] Optionally, the end of the second side plate 212 away from the first connecting plate 213 may be provided with a first connecting structure 2120, which can be connected to the second inner shell 22, so that the second outer shell 21 can be connected to the second inner shell 22.

[0055] The first connecting plate 213 includes a first mating surface 2131 facing the second carrier 20. Specifically, the cross-section of the first mating surface 2131 is arc-shaped, so that the outer surface of the second end 302 of the flexible screen assembly 30 can be attached to the first mating surface 2131. The first mating surface 2131 can be used to constrain the second end 302 of the flexible screen assembly 30 to enter the second carrier 20 or extend from the second carrier 20 at a preset angle.

[0056] Furthermore, the second housing 21 may also include two guide members 214, each guide member 214 being fixed to the surface of one second side plate 212 facing the other second side plate 212. The guide member 214 includes a mounting plate 2141 and a guide portion 2142 protruding from the surface of the mounting plate 2141. The guide portion 2142 has a U-shaped cross-section parallel to the mounting plate 2141, and the opening of the U-shaped guide portion 2142 faces the first carrier 10. Partial structure of the second end 302 of the flexible screen assembly 30 can extend into or unfold from the first carrier 10 along the outer surface of the guide member 214 under the guidance of the guide member 214.

[0057] Specifically, the guide portion 2142 may include a first curved surface 21411 and a second curved surface 21412 disposed opposite to each other. Specifically, the first curved surface 21411 is the outer surface of the guide portion 2142, used to support the inner surface of the second end 302 of the flexible screen assembly 30; the second curved surface 21412 is the inner surface of the guide portion 2142, and the second curved surface 21412 can be used to cooperate with the external structure (specifically the "slider" hereinafter) of the second end 302, so that the guide portion 2142 is located between the inner surface of the second end 302 and the external structure, so that the second end 302 can extend into the first carrier 10 or unfold from the first carrier 10 along the outer surface of the guide member 214 under the guidance of the guide portion 2142.

[0058] The second inner shell 22 may include a main shell 221 and a cover plate 222 connected to the main shell 221. The main shell 221 and the cover plate 222 enclose a receiving space 2210, which can be used to receive a portion of the middle plate 111. Understandably, when the middle plate 111 of the first carrier 10 is received in the receiving space 2210, the second carrier 20 and the first carrier 10 switch to a folded state; when the middle plate 111 of the first carrier 10 moves away from the receiving space 2210, the second carrier 20 and the first carrier 10 switch to an unfolded state.

[0059] Optionally, the main housing 221 may include a substrate 2211 and two third side plates 2212 fixed to both sides of the substrate 2211. The substrate 2211 includes a third surface 22111 and a fourth surface 22112 disposed opposite to each other. The third surface 22111 faces the bottom plate 211, and the fourth surface 22112 faces the cover plate 222. Part of the structure of the third side plate 2212 protrudes from the third surface 22111. The two third side plates 2212 and the third surface 22111 of the substrate 2211 surround to form a first receiving groove 22120, wherein the first receiving groove 22120 can be used to receive the second end 302 of the flexible screen assembly 30. Part of the structure of the third side plate 2212 protrudes from the fourth surface 22112. The two third side plates 2212 and the fourth surface 22112 of the substrate 2211 surround to form a second receiving groove 22122. The second receiving groove 22122 can be used to receive the first inner shell 12 and part of the middle plate 111, thereby enabling the first carrier 10 to switch between an unfolded state and a retracted state.

[0060] Optionally, one end of the third side plate 2212 is connected to the second side plate 212, and the end of the third side plate 2212 facing the second side plate 212 is provided with a second connecting structure 22121. The second connecting structure 22121 can cooperate with the first connecting structure 2120 to realize the connection between the third side plate 2212 and the second side plate 212.

[0061] Specifically, the first connecting structure 2120 can be either a mounting hole or a mounting post, and the second connecting structure 22121 can be either a mounting hole or a mounting post. The mounting post is held and received in the mounting hole, so that the second connecting structure 22121 can cooperate with the first connecting structure 2120, thereby realizing the connection between the third side plate 2212 and the second side plate 212.

[0062] The substrate 2211 is smaller than the base plate 211. Specifically, the substrate 2211 is spaced apart from the base plate 211, and the projection of the substrate 2211 onto the base plate 211 is within the area of ​​the base plate 211. The length of the third side plate 2212 along the unfolding direction of the first carrier 10 and the second carrier 20 is less than the length of the substrate 2211 in the corresponding direction. The two third side plates 2212 are respectively disposed corresponding to the two second side plates 212, and one end of each third side plate 2212 can be connected to one end of a second side plate 212, and its inner and outer surfaces are respectively flush with the inner and outer surfaces of the corresponding second side plate 212.

[0063] Furthermore, the main housing 221 may also include a second connecting plate 2213 fixed to the substrate 2211, the second connecting plate 2213 being disposed opposite to the first connecting plate 213 at a distance. Specifically, the second connecting plate 2213 has a second mating surface 22131 facing the first connecting plate 213, and the cross-sectional shape of the second mating surface 22131 is arc-shaped. Understandably, the second mating surface 22131 and the first mating surface 2131 are spaced apart and surround an annular guide channel 22130, and the guide channel 22130 communicates with the first receiving groove 22120. The second receiving space 220 is formed by the guide channel 22130 and the first receiving groove 22120. In addition, the surface where the second mating surface 22131 is located at least partially coincides with the first curved surface 21411, and the second mating surface 22131 and the first curved surface 21411 can be used to jointly support the flexible screen assembly 30.

[0064] The second end 302 of the flexible screen assembly 30 can enter the first receiving groove 22120 or unfold from the first receiving groove 22120 via the guide channel 22130. Specifically, the outer surface of the second end 302 can be attached to the first mating surface 2131, and the inner surface of the second end 302 can be attached to the second mating surface 22131, so as to constrain the second end 302 of the flexible screen assembly 30 to enter the first receiving groove 22120 or extend from the first receiving groove 22120 at a preset angle.

[0065] In this embodiment, the length of the second connecting plate 2213 is less than the distance between the two second side plates 212, so that the second connecting plate 2213 can be held between the two second side plates 212. In addition, the second connecting plate 2213 and the third side plate 2212 are spaced apart at one end, that is, the second connecting plate 2213 does not directly contact the third side plate 2212, so as to provide clearance space for the second side plate 212 and the third side plate 2212 to connect.

[0066] Optionally, the main housing 221 may further include a support bar 2214, which is received in the second receiving groove 22122 and used to support and fix the cover plate 222. In this embodiment, the support bar 2214 is fixed to the inner surface of the second side plate 212. On the one hand, this reduces the space occupied by the support bar 2214 in the second receiving groove 22122, improves the space utilization of the second receiving groove, and avoids the first carrier 10. On the other hand, it can effectively support the cover plate 222 and improve the stability of the connection between the cover plate 222 and the main body.

[0067] The cover plate 222 abuts against the support bar 2214 and is fixed to the support bar 2214. It can be used to cover the second receiving groove 22122 and form a third receiving space 2220. The third receiving space 2220 can be used to receive the middle plate 111 and the first inner shell 12, so that the first carrier 10 and the second carrier 20 can switch between the folded state and the unfolded state.

[0068] The cover plate 222 may have multiple second limiting strips 2221 arranged side by side, with two adjacent second limiting strips 2221 forming a second limiting groove 2222. The second limiting groove 2222 corresponds to the first limiting strip 1221, and the second limiting strip 2221 corresponds to the first limiting groove 1222. Specifically, the second limiting groove 2222 can be used to hold and accommodate the first limiting strip 1221, and the second limiting strip 2221 can be held and accommodated within the first limiting groove 1222. Understandably, when the first carrier 10 and the second carrier 20 switch between a retracted state and an unfolded state, the first limiting strip 1221 can be locked and slid in the second limiting groove 2222, and the second limiting strip 2221 can be locked and slid in the first limiting groove 1222. This design allows the first carrier 10 and the second carrier 20 to unfold or retract along a preset direction, and also ensures that the first carrier 10 and the second carrier 20 will not sway along a direction perpendicular to the preset direction during unfolding or retracting, thereby improving the stability of the first carrier 10 and the second carrier 20 moving along the preset direction.

[0069] Please refer to Figure 10 , Figure 10 yes Figure 4The diagram shows a three-dimensional representation of a flexible screen assembly in an electronic device. The flexible screen assembly 30 may include a flexible display screen 31, an adhesive layer 32, and a support assembly 33. The flexible display screen 31 may have a display surface 311 and a non-display surface 312. The adhesive layer 32 is located on the non-display surface 312 of the flexible display screen 31. The support assembly 33 is located on the surface of the adhesive layer 32 facing away from the flexible display screen 31 and is connected to the flexible display screen 31 through the adhesive layer 32 to support the flexible display screen 31.

[0070] In this embodiment, the flexible display screen 31 includes a fixed end 313 and a movable end 314. The fixed end 313 is fixed to the first carrier 10 via an adhesive layer 32, specifically to the fixing area 121 of the first inner shell 12, thereby fixing the flexible display screen 31 to the first carrier 10. In other words, the fixed end 313 of the flexible display screen 31 corresponds to the first end 301 of the flexible screen assembly 30, and the fixing area 121 of the first inner shell 12 can be used to fix and support the fixed end 313 of the flexible display screen 31. The movable end 314 is connected to the support assembly 33 via an adhesive layer 32, thereby connecting the flexible display screen 31 to the support assembly 33. In other words, the movable end 314 of the flexible display screen 31 corresponds to the second end 302 of the flexible screen assembly 30, and the support assembly 33 can be used to support the movable end 314 of the flexible display screen 31.

[0071] Understandably, when the first carrier 10 is retracted relative to the second carrier 20, the second end 302 of the flexible screen assembly 30 can be received in the first receiving groove 22120 along the guide channel 22130. When the first carrier 10 is unfolded relative to the second carrier 20, the second end 302 of the flexible screen assembly 30 can extend out of the first receiving groove 22120 along the guide channel 22130.

[0072] Please refer to Figure 11 , Figure 11This is a front view schematic diagram of a support component in a flexible screen assembly in related technologies. In related technologies, the support component 33 may include multiple support members 40, which are spaced apart. Understandably, when the second end 302 of the flexible screen assembly 30 is in a horizontal state, the distance between two adjacent support members 40 is E; when the second end 302 of the flexible screen assembly 30 is in a bent state, that is, when the second end 302 is in the guide channel 22130, the distance between two adjacent support members 40 is F, where F < E, allowing the second end 302 of the flexible screen assembly 30 to bend more effectively. Understandably, a distance E between two adjacent support members 40 facilitates the bending of the second end 302 when it enters the guide channel 22130, making the bending shape of the second end 302 conform to the guide channel 22130. However, during the process of sliding into the guide channel 22130, the second end 302 (especially the part of the structure located on the first carrier 10) is subjected to a squeezing force parallel to the preset direction. Due to the gap between the two adjacent support members 40, the surface of the flexible display screen 31 is very prone to wrinkles or arching, affecting the smoothness and reliability of the flexible screen assembly 30.

[0073] Please refer to Figures 12 to 14 , Figure 12 yes Figure 10 A three-dimensional schematic diagram of the supporting component in the flexible screen assembly shown. Figure 13 yes Figure 12 A magnified view of a portion of region A shown. Figure 14 yes Figure 10 The diagram shows a front view of the support component in the flexible screen assembly. This application provides a novel support component 33, which may include multiple support members 34, with at least a partial structural abutment connection between adjacent support members 34. Adjacent support members 34 are configured to press against each other when the flexible screen slides, thereby supporting and stretching the flexible display screen 31 in the corresponding area of ​​the support member 34.

[0074] In this embodiment, the support member 34 may include a support plate 341 and two baffles 342 fixed to both ends of the support plate 341. The two baffles 342 and the support plate 341 form a fixing groove 3420 for holding and accommodating the flexible display screen 31. The support plates 341 of two adjacent support members 34 are partially connected, or the baffles 342 of two adjacent support members 34 are partially connected. Understandably, the fixing groove 3420 accommodates the flexible display screen 31, constraining it and preventing it from shifting relative to the support assembly 33 during sliding, thus increasing the reliability of the connection between the support assembly 33 and the flexible screen assembly 30.

[0075] In one specific embodiment, the support plates 341 of two adjacent support members 34 are spaced apart, and the baffles 342 of two adjacent support members 34 are at least partially structurally connected. Understandably, when the first carrier 10 retracts relative to the second carrier 20, and the second end 302 of the flexible screen assembly 30 slides on the second carrier 20 (specifically on the cover plate 222), the edges of the baffles 342 can press against each other between the adjacent support members 34, allowing the support plates 341 of the support members 34 to apply a stretching force to the corresponding area of ​​the flexible display screen 31, thereby preventing wrinkling or arching of the surface of the flexible display screen 31 when the second end 302 enters the guide channel 22130.

[0076] Meanwhile, since the support plate 341 is located on the inner surface of the flexible screen assembly 30 when it enters the guide channel 22130 from the second end 302 and bends, the distance between two adjacent support plates 341 in the guide channel 22130, especially the distance on the side closer to the second mating surface 22131, can become smaller or even connected to each other. This is to avoid the support plates 341 squeezing each other and increasing the bending stress of the flexible screen assembly 30, so that the second end 302 can adapt to the current state of the guide channel 22130. When it enters the guide channel 22130 from the second end 302 and bends, since the baffle 342 is located on the outer surface of the flexible screen assembly 30 when it bends, gaps can appear between the baffles 342 that are originally connected to each other, without affecting the bending performance of the flexible screen assembly 30.

[0077] Furthermore, the width of the interface of the baffle 342 parallel to the support plate 341 gradually increases from one end of the support plate 341 to the other end (i.e., the end away from the support plate 341), so that the edge of the baffle 342 away from the support plate 341 can abut against the edge of another baffle 342 away from the support plate 341. This allows the baffles 342 of two adjacent support members 34 to press against each other when the flexible display screen 31 slides, thereby supporting and stretching the flexible display screen 31 in the corresponding area of ​​the support member 34 and improving the flatness of the flexible screen assembly 30. Moreover, when the second end 302 enters the first receiving groove 22120 from the guide channel 22130, because the baffles 342 of the support member 34 are away from the second mating surface 22131, the baffles 342 can separate from each other when bending in the guide channel 22130, ensuring the bending performance of the second end 302 of the flexible display screen 31 in the guide channel 22130.

[0078] In this embodiment, the baffle 342 is approximately an isosceles trapezoid, and the upper base of the isosceles trapezoid is connected to the support plate 341. In other embodiments, the baffle 342 may also be fan-shaped, etc., which will not be listed here.

[0079] Please refer to Figure 15 , Figure 15 yes Figure 14 The diagram shows a modified front view of the support component structure. In another specific embodiment, the support plates 341 of two adjacent support members 34 are at least partially structurally connected, and the cross-sectional width of the support plate 341 gradually decreases from the side where the support plate 341 connects to the baffle 342 to the other side.

[0080] Understandably, since the cross-sectional width of the support plate 341 gradually decreases from one side of the support plate 341 connecting to the baffle 342 to the other side, the ends of two adjacent support plates 341 with larger cross-sectional widths in the flexible screen assembly 30 away from the guide channel 22130 can squeeze each other when the flexible display screen 31 slides, so as to support and stretch the flexible display screen 31 in the corresponding area of ​​the support member 34 and improve the flatness of the flexible screen assembly 30.

[0081] In addition, when the second end 302 of the flexible screen assembly 30 bends as it enters the first receiving groove 22120 from the guide channel 22130, the side with the larger cross-sectional width of the support plate 341 of the two adjacent support members 34 can continue to connect or separate because it is far away from the second mating surface 22131. The gap between the side with the smaller cross-sectional width of the support plate 341 of the two adjacent support members 34 can become smaller or even abut against each other, so that the shape formed by the support assembly 33 can adapt to the second mating surface 22131, thereby ensuring the bending performance of the second end 302 of the flexible display screen 31 in the guide channel 22130.

[0082] In some other specific embodiments, the support plates 341 of two adjacent support members 34 are at least partially structurally connected. Furthermore, the cross-sectional width of the support plate 341 gradually increases from both ends towards the middle, allowing the support plates 341 of two adjacent support members 34 to connect at the middle position, thereby supporting and stretching the flexible display screen 31 in the corresponding area of ​​the support member 34.

[0083] Please continue to refer to Figure 13 Furthermore, the support member 34 may also include a slider 343 (i.e., an external structure of the second end 302), which is disposed on the surface of the support plate 341 facing away from the flexible display screen 31. The slider 343 can cooperate with the guide member 214 of the second housing 21 and move under the constraint of the guide member 214 to ensure that the second end 302 of the flexible screen assembly 30 can fit against the second mating surface 22131 of the first connecting plate 213 during the process of entering the guide channel 22130, thereby allowing the second end 302 to smoothly enter the first receiving groove 22120 and avoid jamming.

[0084] Specifically, the slider 343 includes a connecting portion 3431 and a sliding portion 3432 connected to the connecting portion 3431. The sliding portion 3432 is spaced apart from the support plate 341, and the connecting portion 3431 connects the sliding portion 3432 and the support plate 341. In other words, the connecting portion 3431 is connected to the surface of the support plate 341 facing away from the adhesive layer 32, and the sliding portion 3432 is connected to the end of the connecting portion 3431 away from the support plate 341, so that the guide portion 2142 can be located between the sliding portion 3432 and the support plate 341. That is, the surface of the support plate 341 facing away from the adhesive layer 32 can abut against the first curved surface 21411, and the sliding portion 3432 can slide along the second curved surface 21412.

[0085] Understandably, when the first carrier 10 and the second carrier 20 switch between the folded state and the unfolded state, the guide portion 2142 is sandwiched between the support plate 341 and the sliding portion 3432. On the one hand, this allows the flexible screen assembly 30 to move along the direction of the guide portion 2142. On the other hand, it prevents the flexible screen assembly 30 from detaching from the second mating surface 22131 of the second connecting plate 2213, so that the flexible screen assembly 30 wrinkles or shifts at the guide channel 22130 position, thereby improving the reliability of the second end 302 entering the second accommodating space 220.

[0086] Furthermore, the sliding part 3432 may also include a fixed shaft 3433 and a roller 3434, wherein the fixed shaft 3433 is connected to the connecting part 3431, and the roller 3434 is rotatably connected to the fixed shaft 3433. The roller 3434 can roll on the second curved surface 21412 to reduce friction between the sliding part 3432 and the guide part 2142, making it easier for the sliding part 3432 to slide relative to the guide part 2142. In this embodiment, the fixed shaft 3433 is parallel to the support plate 341 to ensure sufficient contact between the roller 3434 and the second curved surface 21412. In other embodiments, the fixed shaft 3433 may be set at an angle to the support plate 341 to adapt to different environmental requirements; no specific limitations are imposed here.

[0087] In this embodiment, each support member 34 may include two sliding members 343, and the sliding members 343 may be located at both ends of the support plate 341. The two sliding members 343 correspond to and are slidably connected to the guide portions 2142 of the two guide members 214, so that both ends of the support plate 341 can be constrained by the corresponding guide portions 2142 at the same time, so as to prevent the problem of uneven force on one side of the flexible screen assembly 30 from lifting.

[0088] Optionally, the connecting part 3431 and the baffle 342 are misaligned. In other words, the connecting part 3431 is not located at the edge of the support plate 341, so that the projection of the sliding part 3432 on the support plate 341 is within the range of the support plate 341. When the sliding part 343 cooperates with the guide part 2142, the two second side plates 212 of the second carrier 20 are smaller in size, which is beneficial to improving the screen ratio of the electronic device 100.

[0089] In other embodiments, the connecting portion 3431 may be flush with the baffle 342, and the sliding portion 3432 may be located outside the range of the support plate 341. Understandably, when the sliding member 343 cooperates with the guide portion 2142, the second side plate 212 needs to provide sufficient clearance for the guide member 214, which affects the screen ratio of the electronic device 100.

[0090] Please refer to Figures 16 to 19 , Figure 16 yes Figure 10 The diagram shown is a front view of another embodiment of the support component structure. Figure 17 yes Figure 16 The diagram shows a modified front view of the supporting component structure. Figure 18 yes Figure 16 The diagram shown is another modified front view of the supporting component structure. Figure 19 yes Figure 16 The supporting component structure shown also includes a modified front view. In yet another embodiment, the support member 34 includes a support plate 341 having a connecting surface for connecting the adhesive layer 32. The width of the support plate 341 along a cross-section parallel to the connecting surface gradually decreases from one side of the connecting surface to the other side (the side away from the connecting surface).

[0091] Understandably, since the cross-sectional width of the support plate 341 gradually decreases from the connecting surface away from the connecting surface along the direction parallel to the connecting surface, the ends of the two adjacent support plates 341 with larger cross-sectional widths in the flexible screen assembly 30 away from the guide channel 22130 can squeeze each other when the flexible display screen 31 slides, so as to support and stretch the flexible display screen 31 in the corresponding area of ​​the support member 34 and improve the flatness of the flexible screen assembly 30.

[0092] In addition, when the second end 302 of the flexible screen assembly 30 bends as it enters the first receiving groove 22120 from the guide channel 22130, the side with the larger cross-sectional width of the support plate 341 of the two adjacent support members 34 can continue to connect or separate because it is far away from the second mating surface 22131. The gap between the side with the smaller cross-sectional width of the support plate 341 of the two adjacent support members 34 can become smaller or even abut against each other, so that the shape formed by the support assembly 33 can be adapted to the second mating surface 22131, thereby ensuring the bending performance of the second end 302 of the flexible display screen 31 in the guide channel 22130.

[0093] Specifically, the cross-sectional shape of the support plate 341 can be one of trapezoidal, triangular or fan-shaped, and the side of the support plate 341 with the larger surface area faces the flexible display screen 31.

[0094] Furthermore, the support member 34 may also include a slider 343 (i.e., an external structure of the second end 302), which is disposed on the surface of the support plate 341 facing away from the flexible display screen 31. The slider 343 can cooperate with the guide member 214 of the second housing 21 and move under the constraint of the guide member 214 to ensure that the second end 302 of the flexible screen assembly 30 can fit against the second mating surface 22131 of the first connecting plate 213 during the process of entering the guide channel 22130, thereby allowing the second end 302 to smoothly enter the first receiving groove 22120 and avoid jamming.

[0095] Specifically, the slider 343 includes a connecting portion 3431 and a sliding portion 3432 connected to the connecting portion 3431. The sliding portion 3432 is spaced apart from the support plate 341, and the connecting portion 3431 connects the sliding portion 3432 and the support plate 341. In other words, the connecting portion 3431 is connected to the surface of the support plate 341 facing away from the adhesive layer 32, and the sliding portion 3432 is connected to the end of the connecting portion 3431 away from the support plate 341, so that the guide portion 2142 can be located between the sliding portion 3432 and the support plate 341. That is, the surface of the support plate 341 facing away from the adhesive layer 32 can abut against the first curved surface 21411, and the sliding portion 3432 can slide along the second curved surface 21412.

[0096] Understandably, when the first carrier 10 and the second carrier 20 switch between the folded state and the unfolded state, the guide portion 2142 is sandwiched between the support plate 341 and the sliding portion 3432. On the one hand, this allows the flexible screen assembly 30 to move along the direction of the guide portion 2142. On the other hand, it prevents the flexible screen assembly 30 from detaching from the second mating surface 22131 of the second connecting plate 2213, so that the flexible screen assembly 30 wrinkles or shifts at the guide channel 22130 position, thereby improving the reliability of the second end 302 entering the second accommodating space 220.

[0097] Furthermore, the sliding part 3432 may also include a fixed shaft 3433 and a roller 3434, wherein the fixed shaft 3433 is connected to the connecting part 3431, and the roller 3434 is rotatably connected to the fixed shaft 3433. The roller 3434 can roll on the second curved surface 21412 to reduce friction between the sliding part 3432 and the guide part 2142, making it easier for the sliding part 3432 to slide relative to the guide part 2142. In this embodiment, the fixed shaft 3433 is parallel to the support plate 341 to ensure sufficient contact between the roller 3434 and the second curved surface 21412. In other embodiments, the fixed shaft 3433 may be set at an angle to the support plate 341 to adapt to different environmental requirements; no specific limitations are imposed here.

[0098] The flexible screen assembly 30 provided in this application embodiment connects two adjacent support members 34 in the support assembly 33, so that when the flexible display screen 31 slides (specifically when the first carrier 10 and the second carrier 20 switch to the retracted state), the two adjacent support members 34 can squeeze each other to provide horizontal tensile tension for the flexible display screen 31 in the corresponding area, thereby preventing the flexible display screen 31 from arching or wrinkling during the retraction of the electronic device 100 and improving the appearance of the electronic device 100.
