Description

Technical Field

[0001] This application belongs to the technical field of electronic devices, and particularly relates to a folding screen assembly and an electronic device. Background Art

[0002] Folding screen devices are currently a popular branch of electronic products in the market. The structural strength and service life of the folding screen directly affect the core competitiveness of folding screen devices.

[0003] In related technologies, a carbon fiber support plate is provided on the back of the folding screen. To ensure that the folding area of the folding screen can freely stretch, extend, and bend, and to ensure that the folding screen does not have material fatigue fracture problems after repeated folding, a mesh structure needs to be formed at the position of the carbon fiber support plate corresponding to the folding area through an etching process.

[0004] However, the mesh structure cannot provide complete support for the folding screen. Rigid structures such as hinges below the folding screen are likely to directly squeeze the folding screen across the mesh structure during the folding process, resulting in technical problems such as irreversible deformation easily occurring in the bending area of the folding screen and the short service life of the folding screen. Summary of the Utility Model

[0005] This application aims to provide a folding screen assembly and an electronic device, at least solving the technical problems of irreversible deformation easily occurring in the bending area and the short service life of the folding screen.

[0006] To solve the above technical problems, this application is implemented as follows:

[0007] In a first aspect, an embodiment of this application provides a folding screen assembly. The folding screen assembly includes: a screen body, the screen body is a multi-layer stacked structure, the screen body includes a first surface and a second surface, and a display area is formed on the first surface; a protective layer, the protective layer is provided on the second surface of the screen body, and the protective layer includes a clearance area; a first support plate, the first support plate is provided in the clearance area, the first support plate includes a third surface, the third surface faces the screen body, the third surface includes a connection area and a sliding area, the connection area is connected to the second surface, and the sliding area can slide relative to the second surface during the folding process of the screen body.

[0008] In a second aspect, an embodiment of this application provides an electronic device. The electronic device includes: a main body; the folding screen assembly as in the first aspect, and the folding screen assembly is provided on the main body.

[0009] In this technical solution, this application provides a clearance area on the protective layer, and the clearance area corresponds to the middle section of the screen body, that is, the clearance area corresponds to the area where the deformation amplitude of the screen body is relatively large during the folding process. A part of the second surface of the screen body is directly exposed through the hollow area.

[0010] On this basis, a first support plate is arranged in the hollowed-out area. The surface of the first support plate facing the screen body is the third surface. The first support plate is fixed to the second surface of the screen body through the connection area on the third surface. The area on the third surface except the connection area is the sliding area, and there is no connection between the sliding area and the second surface.

[0011] During the process of the screen body switching from the unfolded state to the folded state, the bent screen body pulls the first support plate through the connection area, causing the sliding area on the third surface to slide relative to the second surface. Thus, through this sliding trend, the first support plate will not stretch or extend, that is, the whole first support plate will not become thinner along with the stretching of the screen body, avoiding the loss of the protection ability of the first support plate during the folding process of the screen body. Therefore, the first support plate with strong protection ability can replace the protective layer to contact the rigid structure of the hinge assembly, thereby reducing the probability of irreversible deformation of the screen body under extrusion force and prolonging the service life of the screen body.

[0012] It can be seen that, by setting a clearance area on the protective layer and arranging a first support plate capable of sliding relative to the screen body in the clearance area, the present application solves the technical problems of irreversible deformation easily occurring in the bending area and short service life of the folding screen in the related art, and achieves the technical effects of improving the structural strength of the folding screen assembly, reducing the failure rate of the folding screen assembly, and enhancing the user experience.

[0030] The following will describe a folding screen assembly and an electronic device according to embodiments of the present application in conjunction with Figures 1 to 10 a folding screen assembly and an electronic device according to embodiments of the present application.

[0031] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, a folding screen assembly 100 according to some embodiments of the present application includes: a screen body 110, the screen body 110 is a multi-layer stacked structure, the screen body 110 includes a first surface 1102 and a second surface 1104, and a display area is formed on the first surface 1102; a protective layer 120, the protective layer 120 is disposed on the second surface 1104 of the screen body 110, and the protective layer 120 includes a clearance area 1202; a first support plate 130, the first support plate 130 is disposed in the clearance area 1202, the first support plate 130 includes a third surface 132, the third surface 132 faces the screen body 110, the third surface 132 includes a connection area 1322 and a sliding area 1324, the connection area 1322 is connected to the second surface 1104, and the sliding area 1324 can slide relative to the second surface 1104 during the folding process of the screen body 110.

[0032] In this technical solution, a folding screen assembly 100 applied to an electronic device 200 is defined. The folding screen assembly 100 can change its state through a folding action. Specifically, the folding screen assembly 100 includes an unfolded state and a folded state. In the unfolded state, the folding screen assembly 100 can provide a relatively large display area. In the folded state, the folding screen can be hidden inside the electronic device 200, and other screens on the electronic device 200 can be enabled.

[0033] The folding screen assembly 100 includes a screen body 110 and a protective layer 120. The screen body 110 is a multi-layer stacked structure. The front surface of the screen body 110 is the first surface 1102, and the back surface is the second surface 1104. A display area can be formed on the first surface 1102, and the second surface 1104 is blocked by structures such as the main board, hinge assembly 214, and housing in the electronic device 200. The protective layer 120 is disposed on the second surface 1104 of the screen body 110. On the one hand, the protective layer 120 can provide support for the multi-layer stacked structure above, and on the other hand, the protective layer 120 can form protection under the screen body 110.

[0034] When the folding screen assembly 100 is in the unfolded state, the first surface 1102 is exposed, and the user can observe information or perform touch operations through the display area on the first surface 1102. When the folding screen assembly 100 switches from the unfolded state to the folded state, the middle section of the screen body 110 has a large deformation amplitude. This middle section may be squeezed by the hinge assembly 214 due to deformation. The protective layer 120 needs to deform along with the bending movement of the screen body 110. When the screen body 110 switches to the folded state, the protective layer 120 is forced to stretch and become thinner, so that the protective layer 120 cannot resist the direct impact of rigid structures such as the hinge assembly 214.

[0035] In response to this, the present application provides a clearance area 1202 on the protective layer 120. The clearance area 1202 corresponds to the middle section of the screen body 110, that is, the clearance area 1202 corresponds to the area of the screen body 110 with a large deformation amplitude during the folding process. A part of the second surface 1104 of the screen body 110 is directly exposed through the hollow area.

[0036] On this basis, a first support plate 130 is provided in the hollow area. The surface of the first support plate 130 facing the screen body 110 is the third surface 132. The first support plate 130 is fixed to the second surface 1104 of the screen body 110 through a connection area 1322 on the third surface 132. The area on the third surface 132 other than the connection area 1322 is a sliding area 1324, and there is no connection between the sliding area 1324 and the second surface 1104.

[0037] During the process of the screen body 110 switching from the unfolded state to the folded state, the bent screen body 110 pulls the first support plate 130 through the connection area 1322, causing the sliding area 1324 on the third surface 132 to slide relative to the second surface 1104. Thus, through this sliding trend, the first support plate 130 will not expand or contract, that is, the overall first support plate 130 will not stretch and become thinner along with the screen body 110, avoiding the loss of the protection ability of the first support plate 130 during the folding process of the screen body 110. Therefore, the first support plate 130 with strong protection ability can replace the protective layer 120 to contact the rigid structure of the hinge assembly 214, thereby reducing the probability of irreversible deformation of the screen body 110 under the extrusion force and extending the service life of the screen body 110.

[0038] It can be seen that the present application solves the technical problems of irreversible deformation easily occurring in the bending area and short service life of the folding screen in the related art by providing a clearance area 1202 on the protective layer 120 and providing a first support plate 130 that can slide relative to the screen body 110 in the clearance area 1202, achieving the technical effects of improving the structural strength of the folding screen assembly 100, reducing the failure rate of the folding screen assembly 100, and enhancing the user experience.

[0039] As Figure 1 , Figure 3 and Figure 4 shown, in some embodiments of the present application, optionally, the screen body 110 includes a first direction ( Figure 3 the arrow a in the figure shows), and the screen body 110 can be bent relative to the first direction; the protective layer 120 includes a first protective layer 122 and a second protective layer 124, the first protective layer 122 and the second protective layer 124 are arranged at intervals along the first direction, and a clearance area 1202 is formed between the first protective layer 122 and the second protective layer 124.

[0040] In this technical solution, the screen body 110 includes a first direction, the first direction corresponds to the length direction of the screen body 110, and the screen body 110 can be bent relative to the first direction. Specifically, when the screen body 110 is switched from the unfolded state to the folded state, the length of the screen body 110 is halved.

[0041] On this basis, the first protective layer 122 and the second protective layer 124 are arranged on the second surface 1104 of the screen body 110, the first protective layer 122 and the second protective layer 124 are arranged at intervals in the first direction, and a gap between the first protective layer 122 and the second protective layer 124 forms the clearance area 1202, that is, the first support plate 130 is installed between the first protective layer 122 and the second protective layer 124.

[0042] Among them, the clearance area 1202 between the first protective layer 122 and the second protective layer 124 corresponds to the middle section of the screen body 110. The middle section of the screen body 110 has a large deformation amplitude during the folding process, and the middle section of the screen body 110 is generally arranged opposite to the hinge assembly 214.

[0043] For this, by arranging the first support plate 130 that will not be stretched and thinned along with the screen body 110 between the first protective layer 122 and the second protective layer 124, the first support plate 130 can resist the extrusion of the hinge assembly 214 for the screen body 110, so that the first support plate 130 can provide reliable protection for the screen body 110 during the folding process, thereby reducing the probability that obvious creases appear in the middle section of the screen body 110, or the middle section of the screen body 110 cannot be normally displayed, and further solving the technical problems of irreversible deformation easily occurring in the bending area and short service life of the folding screen in the related art.

[0044] On this basis, the area of the screen body 110 covered by the first protective layer 122 and the second protective layer 124 has a relatively small deformation amplitude during the bending process, the first protective layer 122 and the second protective layer 124 are stretched and thinned to a relatively small extent along with the screen body 110, and the area of the screen body 110 covered by the first protective layer 122 and the second protective layer 124 is generally misaligned with the hinge assembly 214. Therefore, the first protective layer 122 and the second protective layer 124 can cooperate with the first support plate 130 to provide reliable protection for the second surface 1104 of the screen body 110, reduce the probability of damage to the screen body 110 during the bending process, and further achieve the technical effects of improving the structural stability of the folding screen assembly 100 and reducing the failure rate of the folding screen assembly 100.

[0045] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, in some embodiments of the present application, optionally, a first support plate 130 is disposed in the clearance area 1202, and the first support plate 130 is centrally disposed between the first protective layer 122 and the second protective layer 124.

[0046] In this technical solution, a first support plate 130 is disposed in the clearance area 1202, and a first support plate 130 is centrally disposed in the clearance area 1202 between the first protective layer 122 and the second protective layer 124. When the length of the first support plate 130 is less than the length of the clearance area 1202, there are gaps between the two ends of the first support plate 130 and the protective layer 120. When the length of the first support plate 130 is the same as the length of the clearance area 1202, the two ends of the first support plate 130 are in contact with the protective layer 120.

[0047] By limiting the number of the first support plates 130 to one, it is possible to avoid mutual interference among multiple first support plates 130 during the sliding process, so that on the one hand, the folding smoothness of the folding screen assembly 100 is ensured, and on the other hand, it is prevented that the first support plates 130 fall off due to mutual collision.

[0048] For the screen body 110, the closer to the middle section of the screen body 110, the greater the bending deformation amplitude and the higher the possibility of contacting the hinge assembly 214. By centrally disposing a first support plate 130 in the clearance area 1202, it can be ensured that the first support plate 130 can cover the middle area of the screen body 110 with a relatively large deformation amplitude and a relatively high possibility of being squeezed by the hinge assembly 214, thereby improving the protection effect of the first support plate 130 on the screen body 110 and extending the service life of the screen body 110.

[0049] As Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments of the present application, optionally, in the first direction, the two ends of the first support plate 130 are respectively spaced apart from the first protective layer 122 and the second protective layer 124; in the first direction, the connection area 1322 is located in the middle of the third surface 132, and the sliding areas 1324 are located on both sides of the connection area 1322.

[0050] In this technical solution, the two ends of the first support plate 130 are respectively spaced apart from the first protective layer 122 and the second protective layer 124, leaving a gap at the two ends of the first support plate 130 and the second support plate 160. This gap can provide a deformation allowance for the first protective layer 122 and the second protective layer 124, preventing the first protective layer 122 and the second protective layer 124 from colliding with the two ends of the first support plate 130 during the process of the screen body 110 switching from the folded state to the unfolded state, thereby improving the structural stability of the folding screen assembly 100 and reducing the probability of loosening and dislocation of the first support plate 130.

[0051] On this basis, the connection area 1322 is arranged in the middle of the third surface 132, and two sliding areas 1324 are respectively arranged on both sides of the connection area 1322. By arranging the connection area 1322 in the middle of the third surface 132, the first support plate 130 can always be kept in the centered position. During the folding process, the two ends of the first support plate 130 close to the first protective layer 122 and the second protective layer 124 slide relatively, and the middle of the first support plate 130 is closely attached to the middle of the screen body 110, thereby improving the protection effect of the first support plate 130 on the weak area of the screen body 110 and achieving the technical effects of reducing the failure rate of the screen body 110 and extending the service life of the screen body 110.

[0052] As Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, in some embodiments of the present application, optionally, a plurality of first support plates 130 are arranged in the clearance area 1202; the plurality of first support plates 130 are distributed in the first direction.

[0053] In this technical solution, a plurality of first support plates 130 are arranged between the first protective layer 122 and the second protective layer 124.

[0054] The first support plate 130 can reduce the stretching and thinning amplitude through the sliding trend, but cannot eliminate the stretching and thinning trend.

[0055] In this regard, compared with the solution of setting a single first support plate 130, setting multiple first support plates 130 can reduce the degree of stretching and thinning of the first support plate 130 during the folding process, thereby enhancing the protection ability of the first support plate 130 for the screen body 110, reducing the probability of the screen body 110 being damaged by extrusion of the hinge assembly 214, and further achieving the technical effects of enhancing the structural stability of the folding screen assembly 100 and extending the service life of the folding screen assembly 100.

[0056] On the other hand, compared with the solution of setting a single first support plate 130, setting multiple first support plates 130 can reduce the rebound force caused by the bending of the first support plate 130, and can provide favorable conditions for the magnet design of the electronic device 200 and the torque design of the hinge assembly 214.

[0057] Specifically, the number of the first support plates 130 can be selected according to the size of the screen body 110 and the deformation amplitude of the middle section of the screen body 110. For example, two first support plates 130, three first support plates 130 or four first support plates 130 can be set. This technical solution is not rigidly limited in this regard, as long as the protection requirements of the screen body 110 are met.

[0058] Such as Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in, in some embodiments of the present application, optionally, two first support plates 130 are provided in the clearance area 1202. The two first support plates 130 are symmetrically arranged between the first protective layer 122 and the second protective layer 124, and the two first support plates 130 are spaced apart; in the first direction, the connection area 1322 is close to the protective layer 120, and the sliding area 1324 is far from the protective layer 120.

[0059] In this technical solution, two first support plates 130 are provided between the first protective layer 122 and the second protective layer 124. The two first support plates 130 are spaced apart from each other, and the two first support plates 130 are symmetrically distributed between the first protective layer 122 and the second protective layer 124.

[0060] Specifically, the connection area 1322 on the first support plate 130 is close to the adjacent protective layer 120, and the sliding area 1324 is far from the protective layer 120 relative to the connection area 1322. When the screen body 110 is in the unfolded state, the two sliding areas 1324 are located between the two connection areas 1322.

[0061] By bringing the connection area 1322 on the first support plate 130 closer to the protective layer 120 and moving the sliding area 1324 on the first support plate 130 away from the protective layer 120, it is possible to prevent the first support plate 130 from sliding and colliding with the protective layer 120, thereby improving the smoothness of the folding process of the folding screen assembly 100 and preventing problems such as misalignment and detachment of the first support plate 130 due to collision.

[0062] Similarly, by arranging the first support plate 130 and the second support plate 160 at intervals, it is possible to prevent the two first support plates 130 from colliding with each other during the folding process, thereby improving the smoothness of the folding process of the folding screen assembly 100 and preventing problems such as misalignment and detachment of the first support plate 130 due to collision. Furthermore, the technical effects of improving the structural stability of the folding screen assembly 100 and reducing the failure rate of the folding screen assembly 100 are achieved.

[0063] As Figure 1 、 Figure 5 and Figure 9 shown, in some embodiments of the present application, optionally, the folding screen assembly 100 further includes: an adhesive layer 140, the adhesive layer 140 is disposed between the second surface 1104 and the connection area 1322, and the adhesive layer 140 bonds the second surface 1104 and the connection area 1322; a first sliding layer 150, the first sliding layer 150 is disposed between the second surface 1104 and the sliding area 1324, the first sliding layer 150 is bonded to the sliding area 1324, and the first sliding layer 150 can slide on the second surface 1104.

[0064] In this technical solution, an adhesive layer 140 is filled between the second surface 1104 of the screen body 110 and the connection area 1322 of the first support plate 130. The adhesive layer 140 bonds the screen body 110 and the first support plate 130 together, so that the first support plate 130 can be positioned below the screen body 110, preventing the first support plate 130 from laterally moving in the clearance area 1202, thereby improving the reliability and stability of the folding screen assembly 100.

[0065] Specifically, the adhesive layer 140 includes a glue layer or a double-sided adhesive layer.

[0066] On this basis, a first sliding layer 150 is attached to the sliding area 1324. After assembly, the first sliding layer 150 is located between the second surface 1104 and the sliding area 1324, and the first sliding layer 150 remains in contact with the second surface 1104. The roughness of the first sliding layer 150 is less than that of the first support plate 130. By providing the first sliding layer 150 between the sliding area 1324 and the second surface 1104, the sliding resistance can be reduced, thereby improving the smoothness of the sliding of the first support plate 130 relative to the screen body 110, and further improving the smoothness of the folding operation of the folding screen assembly 100.

[0067] As shown in Figure 1 , Figure 5 and Figure 9 , in some embodiments of the present application, optionally, the folding screen assembly 100 further includes: a second support plate 160 disposed on the side of the protective layer 120 facing away from the screen body 110. The second support plate 160 includes an etching area 1602 which is a mesh structure, and the etching area 1602 is disposed opposite to the first support plate 130; a second sliding layer 152 disposed between the first support plate 130 and the second support plate 160. The second sliding layer 152 is bonded to the first support plate 130 and can slide on the second support plate 160.

[0068] In this technical solution, a second support plate 160 is disposed on the side of the protective layer 120 facing away from the screen body 110. The second support plate 160 covers the surface of the protective layer 120 facing away from the screen body 110, and the second protective layer 124 shields the clearance area 1202. After assembly, the first support plate 130 is clamped between the screen body 110 and the second support plate 160, and the second support plate 160 faces the inner side of the electronic device 200. The second device can block rigid structures such as the main board, the hinge assembly 214, and the housing.

[0069] It can be seen that the second support plate 160 can provide support and protection for the screen body 110, the protective layer 120, and the first support plate 130, so as to reduce the failure rate of the screen body 110 and extend the service life of the screen body 110.

[0070] On this basis, to ensure that the middle section of the screen body 110 can freely stretch, extend, and bend, and to ensure that the screen body 110 does not have material fatigue fracture problems after repeated folding, the second support plate 160 needs to form a mesh structure in the area corresponding to the middle section of the screen body 110 through an etching process. However, rigid structures such as the hinge assembly 214 may cross the etching area 1602 through the pores in the mesh structure.

[0071] In response to this, by disposing the first support plate 130 in the clearance area 1202 opposite to the etching area 1602, the first support plate 130 that can reduce the stretching and thinning amplitude through sliding can replace the protective layer 120 to resist the extrusion force exerted by the hinge assembly 214, reduce the negative impact of the extrusion force on the screen body 110, thereby solving the technical problems of irreversible deformation easily occurring in the bending area and short service life of the folding screen in the related art, and achieving the technical effects of improving the structural strength of the folding screen assembly 100, reducing the failure rate of the folding screen assembly 100, and improving the user experience.

[0072] Specifically, the second support plate 160 is formed by a carbon fiber material.

[0073] As shown in Figure 10As shown in the figure, an embodiment of the present application provides an electronic device 200, which includes: a main body 210; and a folding screen assembly 100 as described in any of the above technical solutions, and the folding screen assembly 100 is disposed on the main body 210.
