[0043] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar elements, unless otherwise represented. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they only represent examples of devices consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0044] In the description of the present disclosure, it needs to be understood that the terms "center", "upper", "lower", "top", "horizontal", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or position of the user when using the terminal, and are not intended as a limitation of the present disclosure.

[0045] As shown in Figures 4 to 12 , the present embodiment provides a terminal, comprising:

[0046] a folding screen assembly;

[0047] a housing 110, comprising a first housing 114 and a second housing 115, the first housing 114 and the second housing 115 are connected through a bending area, and the first housing 114 and the second housing 115 are used to carry the folding screen assembly;

[0048] the bending area comprises:

[0049] a first sealing body 120 located at the side of the bending area, constituting a first sealing surface, sealing the gap between the folding screen assembly and the housing 110.

[0050] In the present embodiment, the first sealing body is located at the side of the bending area, which reduces the entry of external dust, liquid and light into the terminal through the gap between the folding screen assembly and the housing, and improves the sealing performance of the bending area. Moreover, the first sealing body fills the pores generated during the deformation of the bending area, so that the first sealing body adapts to the deformation of the bending area, and ensures the conversion function of the terminal between bending and flattening.

[0051] Without limitation, the deformation of the first sealing body can only rely on the characteristics of its own material, for example, the first sealing body is made of plastic material, and the elastic deformation of the plastic material can absorb the deformation of the bending area. Or, the deformation of the first sealing body relies on its own structural characteristics, for example, the sealing body has a bending part, which absorbs the deformation of the bending area by compression and expansion of the bending part.

[0052] As shown in Figures 4 to 6 , the first sealing body 120 deforms with the bending of the flexible folding screen assembly; as Figure 9 , Figure 10 and Figure 11As shown, in the unfolded state, the first sealing body 120 also recovers the deformation along with the unfolding of the flexible folding screen assembly.

[0053] The bending region includes an abutment region of the first housing 114 and the second housing 115, which can be a part of the first housing 114 and the second housing 115 disconnected in the first housing 114 and the second housing 115. Figure 4 、 Figure 5 and Figure 11 The first housing 114 and the second housing 115 can rotate relative to each other through the outer folding region, and drive the folding screen assembly to switch between bending and flattening.

[0054] The mutual rotation between the first housing 114 and the second housing 115 can realize the inner folding or outer folding of the folding screen assembly. The inner folding refers to the bending process in which the folding screen assembly is gradually hidden, and when the inner folding reaches the maximum extent, the folding screen assembly can be completely hidden on the inside, and the housing is exposed on the outside. Correspondingly, when the outer folding, the rotation direction of the first housing 114 and the second housing 115 is opposite, the outer folding is the bending process in which the folding screen assembly is gradually exposed, and when the outer folding reaches the maximum extent, the first housing 114 and the second housing 115 can be almost completely hidden on the inside, while the folding screen assembly is exposed on the outside.

[0055] In some specific examples, the bending region can also include a rotating shaft connecting the first housing 114 and the second housing 115, and the first housing 114 can rotate relative to the second housing 115 through the rotating shaft. The rotating shaft is not limited to shaft-type rotating connection components, but also includes non-shaft-type rotating connection components, for example: the rotating shaft can also be a gear-type rotating connection component, or a rotating connection component formed by a folding piece, etc.

[0056] The terminal includes but is not limited to a mobile phone, a tablet computer, a notebook computer, a display, an e-reader, a television, a wearable device, or a vehicle-mounted computer, etc. electronic devices with display screens.

[0057] In other optional embodiments, the first sealing body includes:

[0058] a connecting part connected with the housing;

[0059] a first telescopic part connected with the connecting part and the folding screen assembly, and the first telescopic part can be telescoped according to the bending state of the folding screen assembly.

[0060] In the embodiments of the present disclosure, the connecting part is used to fix the first sealing body, and the first telescopic part is used to absorb the deformation of the bending region, at this time, the first sealing body relies on its own structural characteristics to absorb the deformation of the bending region. In the case of unfolding the terminal (i.e. in the case of unfolding the terminal), the first telescopic part is in a contracted state, and in the case of folding the electronic device, the first telescopic part is in an expanded state to fill the space introduced by the folding of the device, thereby further playing a sealing role.

[0061] Non-limitingly, as shown in Figure 11 and Figure 12 , the side of the first sealing body along the first direction abuts against the shell, the side of the first sealing body along the second direction is adhered to the shell by an adhesive, and the bottom of the first sealing body is adhered to the shell by an adhesive. The two sides of the first sealing body 120 along the first direction are not fixed to the shell 110, reducing the restriction of the shell 110 on the first stretchable part 121 during deformation, ensuring the deformation function of the first stretchable part 121. As shown in Figure 11 , the connecting part 122 is adhered and fixed to the shell 110, strengthening the connection between the shell 110 and the first sealing body 120. Among them, the first direction is parallel to the center line of the bending area, and when the terminal includes a rotating shaft, the first direction is also the axial direction of the rotating shaft, and the second direction is perpendicular to the first direction.

[0062] In other optional embodiments, the first stretchable part includes one or more connected folding pieces; wherein the folding form and / or folding degree of the first stretchable part is different when the folding screen assembly is unfolded and bent.

[0063] When the terminal is unfolded, the folding pieces are in a folded state; when the terminal is folded, the folding degree of the folding pieces in a part of the area of the first stretchable part can be relieved, even unfolded, to fill the space introduced by the folding of the device, thereby further playing a sealing role.

[0064] As shown in Figure 4 , Figure 11 and Figure 12 , when the folding pieces 1211 are multiple, the multiple folding pieces 1211 can be sequentially connected end to end to form a stretching and folding mechanism similar to a folding fan or an accordion. In the bent state, the folding pieces 1211 are compressed under stress, the folding degree of the folding pieces 1211 increases, and when bent to the maximum degree, the folding form of the first stretchable part 121 can be in the shape of a U or a water droplet; in the unfolded state, the folding degree of the folding pieces 1211 decreases, or the folding pieces 1211 return to the original state without stress, and when unfolded to the maximum degree, the folding form of the first stretchable part 121 can be in a horizontal state.

[0065] The folding pieces can be formed by bending a sheet material, and the bent part of the folding pieces forms a groove. Because of the bending, the deformation process of the folding pieces is to extrude the gas in the groove, and the process of different parts of the folding pieces approaching each other is also the process of increasing the hardness of the first stretchable part. Compared with the elastic deformation of the material itself, the first stretchable part of this structure has smaller hardness even after compression deformation, which reduces the extrusion of the first sealing body on the folding screen assembly and can better adapt to the deformation of the folding screen assembly.

[0066] Non-limitingly, the cross section of the single folding piece can be V-shaped, U-shaped, or arched, etc.

[0067] The connecting part can be surrounded by the first telescopic part along the circumferential side. As shown in Figures 4 to 11 , taking the first sealing body 120 with a rectangular cross section as an example, the connecting part 122 can be connected outside the two short sides 1222 and one long side 1221 of the first sealing body 120.

[0068] In other optional embodiments, the connecting part has a second telescopic part on the side of the bending area facing away from the first telescopic part, and the top end of the second telescopic part is provided with a plurality of openings;

[0069] The distance between adjacent openings gradually decreases from the maximum value to 0 during the process of closing to unfolding of the folding screen assembly.

[0070] In the embodiments of the present disclosure, the distance between adjacent openings is different when the folding screen assembly is unfolded and bent. And the distance between adjacent openings can be non-linearly reduced or reduced according to the change of the angle during the process of closing to unfolding of the folding screen assembly. The second telescopic part is located on the side of the connecting part facing away from the first telescopic part, and the second telescopic part realizes telescopic movement through the plurality of openings. The distance between adjacent openings of the folding screen assembly in the unfolded state is less than the distance between adjacent openings of the folding screen assembly in the bent state. Specifically, when the folding screen assembly is bent, the distance between the plurality of openings of the second telescopic part increases, wherein the distance between the openings located at different positions can be different. For example, the distance between adjacent openings is larger at the central position where the deformation of the bending area is larger, and the distance between adjacent openings is smaller at the edge position where the deformation of the bending area is smaller, at this time, the second telescopic part is in an extended state. In contrast, when the folding screen assembly is unfolded, the distance between the plurality of openings decreases, and even adjacent openings can be tightly attached to each other, at this time, the second telescopic part is in a contracted state. The change of the distance between adjacent serrations can better absorb the deformation effect of the folding screen assembly, and further reduce the hardness of the first sealing body when bending.

[0071] In a specific example, when the bending area includes a rotating shaft, as shown in Figure 4 and Figure 5 , and Figures 7 to 11 , the top of the first telescopic part 121 is not connected with the connecting part 122, and the bottom of the first telescopic part 121 opposite to the rotating shaft is connected with the connecting part 122, wherein the part of the connecting part 122 opposite to the rotating shaft is provided with a plurality of openings 123, and the part of the connecting part 122 opposite to the rotating shaft is not fixedly connected with the rotating shaft, but can be separated from each other, so as to reduce the influence on the mutual switching process between the bent state and the flat state. Non-limitingly, the openings are serrations. For example, the openings include but are not limited to triangular serrations, rectangular serrations, or trapezoidal serrations.

[0072] In other optional embodiments, the bending area further comprises:

[0073] A second sealing body is located between the first shell and the second shell, and is used to seal the gap between the openings in different states.

[0074] In actual applications, the folding screen has different gaps between adjacent openings in different bending states during the bending process. The second sealing body can seal the gap between adjacent openings, further improving the sealing effect of the terminal.

[0075] Without limitation, the second sealing body is part of the shell, for example, as shown in Figure 6 The edge of the shell is reused as the second sealing body 180. Alternatively, the second sealing body is a structure of the shell that cooperates with the opening, where the cooperating structure can be a tooth-shaped structure, etc. By wrapping the second sealing body on the outside of the shell, the gap between adjacent openings can be directly sealed.

[0076] In other optional embodiments, the first sealing body comprises one or more flexible films, and the flexible films are connected to the shell and the folding screen assembly at the bending area to form a sealing surface.

[0077] In addition to the first sealing body with the above-mentioned structure of the connecting portion and the first telescopic portion, the first sealing body can also be one or more flexible films. The flexible films can form a sealing surface by being connected to the sealing shell and the folding screen assembly, and the flexible films can seal the gap between the folding screen assembly and the shell in different states such as the folded state and the unfolded state by using the stretchability of the flexible films, thereby ensuring the sealing effect of the terminal.

[0078] In other optional embodiments, cavities are formed between the multiple flexible films, and the cavities are filled with stretchable materials.

[0079] In some specific examples, the stretchable material can be a gas, such as air, etc. In other specific examples, the flexible film can be directly made of an elastic member with a high stretch ratio, such as a plastic material such as silicone rubber, etc.

[0080] As shown in Figure 12 In other optional embodiments, the edge of the shell 110 covers the top of the first sealing body 120 to form a deformation limiting structure 170 of the first sealing body 120.

[0081] As shown in Figure 12As shown, the limiting structure 170 includes an abutting surface 112 opposite to the bottom of the sealing body 120 and an abutting surface 1131 opposite to the top of the sealing body 120, and the abutting surface 112 and the abutting surface 1131 form the limiting surface of the first sealing body 120. Specifically, at the edge 111 of the housing 110, the top of the housing 110 includes a protruding portion 113 protruding towards the center of the housing 110, which covers the top of the sealing body 120, and the abutting surface 1131 opposite to the first sealing body 120 of the protruding portion 113 limits the first sealing body 120. Reducing the upward protrusion of the sealing body 120 after the bending-to-flat transition can reduce the pushing force of the first sealing body 120 on the folding screen assembly to make the folding screen assembly protrude out of the housing 110 after being flattened, resulting in an uneven folding screen assembly in the unfolded state.

[0082] In addition, the top of the housing also has a shielding effect and a protection effect on the first sealing body.

[0083] Further, as shown, Figure 12 the bottom of the first sealing body 120 is at least partially opposite to the bottom of the housing 110. In actual application, the housing 110 forms a cavity, which can be used to accommodate components such as the folding screen 150 and can also reserve space for the first sealing body 120. At this time, the abutting surface 112 opposite to the bottom of the housing 110 and the first sealing body 120 also limits the first sealing body, and the limiting effect of the abutting surface 112 on the first sealing body 120 has an upward pushing force, which cooperates with the limiting effect of the limiting structure to further ensure the flatness of the folding screen assembly after the bending-to-flat transition.

[0084] As shown, Figure 12 in other optional embodiments, the limiting structure 170 includes a groove 1132 opposite to the first sealing body 120.

[0085] The terminal further includes a limiting rib 140 located in the groove 1132.

[0086] Further, the limiting rib also has a sealing effect, and the limiting rib is located between the edge of the housing and the side of the sealing body away from the center of the housing in the first direction, and seals the gap between the edge of the housing and the side of the first sealing body away from the center of the housing in the first direction.

[0087] As shown, Figure 7 and Figure 12 Since the two sides of the first telescopic part 121 in the first direction do not need to be fixedly connected with the housing 110, there will be a gap between the two sides of the first telescopic part 121 in the first direction and the housing 110 during the bending or flattening process, and the limiting rib 140 can reduce the entry of dust or liquid from the outside into the terminal through the gap between the first telescopic part 121 and the outer side 1223 of the housing 110, thereby further improving the sealing effect.

[0088] As shown in Figure 12 The limiting rib 140 is located below the protruding portion 113.

[0089] As shown in Figure 7 The length of the limiting rib 140 along the second direction is the same as the length of the first sealing body 120 along the second direction, so as to further ensure the sealing effect. The second direction is perpendicular to the first direction.

[0090] Non-limitingly, the limiting rib 140 and the first sealing body 120 are in a one-piece structure.

[0091] As shown in Figures 4 to 12 In other optional embodiments, the folding screen assembly comprises:

[0092] A folding screen 150;

[0093] A flexible transparent cover plate 130 located above the folding screen 150;

[0094] The edge of the transparent cover plate 130 is adhered to the top of the first sealing body 120 by an adhesive 160.

[0095] As shown in Figures 4 to 12 The flexible transparent cover plate 130 is located at the outermost side of the terminal, which protects the folding screen 150, and the image displayed by the folding screen 150 can be seen by the user through the flexible transparent cover plate 130.

[0096] The flexible transparent cover plate itself has flexibility and can be bent and folded.

[0097] The flexible transparent cover plate is a deformable transparent cover plate, and non-limitingly, the flexible transparent cover plate can be made of flexible glass.

[0098] As shown in Figure 12 The folding screen 150 is mounted on the housing 110, and the edge of the flexible transparent cover plate 130 can be fixed on the top of the first sealing body 120 by a tape or an adhesive 160.

[0099] The connection of the flexible transparent cover plate and the first sealing body further ensures the stability of the first sealing body and improves the integrity of the first sealing body and the housing.

[0100] The adhesive includes but is not limited to an epoxy resin adhesive or an acrylate adhesive.

[0101] In other optional embodiments, the number of the first sealing bodies is at least two groups, and the at least two groups of first sealing bodies are respectively located at the two ends of the rotating shaft. One group of first sealing bodies comprises one first sealing body or a plurality of first sealing bodies arranged side by side.

[0102] In practical applications, the first seal is located between the end of the shaft and the edge of the housing. For example... Figure 11 As shown in section A, when the flexible transparent cover 130 is unfolded, the first sealing body 120 is distributed perpendicularly to the rotating shaft. The first sealing body 120 can be installed only at the two ends of the rotating shaft to seal the entrance of the gap between the flexible transparent cover 130 and the housing 110. It is not necessary to set a first sealing body 120 with a length similar to that of the rotating shaft, which helps to save the amount of first sealing body used and reduce costs.

[0103] In other alternative embodiments, the foldable screen is a flexible screen; or, the foldable screen includes:

[0104] The first hard screen is installed on the first housing;

[0105] The second hard screen is installed on the second housing, and the second hard screen and the first hard screen are arranged side by side.

[0106] When the first housing bends relative to the second housing via the pivot, it causes the first hard screen to bend relative to the second hard screen.

[0107] When the folding screen is a flexible screen, it covers both the first and second shells, as well as the hinge portion, and utilizes the deformability of the flexible screen to achieve the folding or unfolding of the terminal.

[0108] When a foldable screen consists of two rigid screens, one rigid screen is aligned with the first housing, and the other rigid screen is aligned with the second housing, with a gap between the two rigid screens. A flexible transparent cover can cover the gap between the two rigid screens, ensuring the integrity of the terminal's outer surface.

[0109] Generally, in its unfolded state, the terminal offers a large-screen display. In its folded state, the inward fold conceals the foldable screen, protected by the exposed outer casing. Alternatively, when folded outward, the two opposite surfaces of the terminal display different content, allowing the terminal to function as two independent electronic devices for use by two different users facing each other.

[0110] The first and second hard screens can each have independent communication, playback, or gaming functions. For example, the first hard screen can function as a display screen, while the second hard screen can function as an operation screen. Another example is that the first hard screen displays video footage, while the second hard screen displays play, pause, and / or progress bar controls. Yet another example is that the first hard screen displays content, while the second hard screen displays a virtual keyboard for keyboard use.

[0111] This disclosure also provides a foldable screen module, including a foldable screen assembly and a first sealing body, which is applied to the terminal described in any of the above embodiments.

[0112] In the folding screen assembly, the first sealing body can be the first sealing body in any of the above embodiments.

[0113] The features disclosed in several product embodiments of the present disclosure can be combined arbitrarily without conflict, to obtain new product embodiments.

[0114] Other embodiments of the present disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein.
