Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of an electronic device in an expanded state according to an embodiment of the present disclosure, fig. 2 is a front view of the electronic device in the embodiment shown in fig. 1, and fig. 3 is a schematic cross-sectional diagram of the electronic device at line iii-iii in the embodiment shown in fig. 2. The electronic device 100 may include a first housing 10, a second housing 20 slidably connected to the first housing 10, a display module 30 disposed on the first housing 10 and the second housing 20, and a supporting plate 40 disposed between the display module 30 and the first housing 10 and the second housing 20 respectively for supporting the display module 30. The first casing 10 and the second casing 20 slide relative to each other to change the overall volume of the electronic device 100. The supporting plate 40 is disposed on the first casing 10 and the second casing 20 to form a supporting surface on the first casing 10 and the second casing 20 to support the display module 30. The size of the area of the supporting surface may be changed when the first casing 10 and the second casing 20 slide relatively. The display module 30 can be at least partially disposed on the supporting surface and supported by the supporting plate 40, so that the size of the exposed portion can be changed when the area of the supporting surface is changed. The exposed portion of the display module 30 is a non-display surface on a side close to the supporting plate 40, and a display surface on a side far away from the supporting plate 40, so as to display information on the display surface.

It is understood that in some embodiments, the first casing 10, the second casing 20 and the support plate 40 may form the casing assembly 200, and of course, the casing assembly 200 may not be limited to the first casing 10, the second casing 20 and the support plate 40, but may also include other structures. The supporting surface may be the surface of the housing assembly 200 where the supporting plate 40 is exposed at the side where the display module 30 is disposed. In some embodiments, the display module 30 and the supporting plate 40 may form the display assembly 300, and of course, the display assembly 300 may not be limited to the display module 30 and the supporting plate 40, but may also include other structures.

In addition, the terms "first", "second", "third", etc. in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," "third," etc. may explicitly or implicitly include at least one of the feature.

Referring to fig. 1, 2 and 3, the first housing 10 and the second housing 20 can be made of hard materials, and the materials of the two can be the same or different. The first casing 10 and the second casing 20 may be formed by compounding one or more materials. The first housing 10 is slidably connected to the second housing 20 to form an integral enclosure of the electronic device 100. The first housing 10 and the second housing 20 cooperate to carry and mount a circuit board (on which a control unit such as a processor and other devices, for example), a battery, a camera, a sensor and other electronic components, and also carry the supporting plate 40, and also accommodate a portion of the display module 300.

The first housing 10 and the second housing 20 can be slidably connected through a matching relationship between a slide rail and a slide block, a matching relationship between a telescopic structure and the like. Of course, the sliding connection may also be realized in other manners, which will not be described in detail.

The first casing 10 and the second casing 20 are slidable relative to each other, so that the first casing 10 and the second casing 20 overlap each other, and the overall volume of the electronic device 100 is changed. The first casing 10 and the second casing 20 can be in a folded state by enlarging the overlapping portion. The first casing 10 and the second casing 20 may be in the unfolded state by the reduction of the overlapping portion.

In some embodiments, when the first housing 10 and the second housing 20 slide relatively, the second housing 20 can also slide partially into the first housing 10, so that the first housing 10 and the second housing 20 overlap each other. The first casing 10 and the second casing 20 can be in the folded state by enlarging the second casing 20 in the first casing 10. The first casing 10 and the second casing 20 may be in the unfolded state by reducing the portion of the second casing 20 inside the first casing 10. That is, the second casing 20 can slide relative to the first casing 10 to slide into the first casing 10 to be in a folded state, and slide out of the first casing 10 to be in an unfolded state.

The second housing 20 is internally provided with rollers 21 for supporting the support plate 40. The axial direction of the roller 21 can be perpendicular to the sliding direction of the first casing 10 and the second casing 20, so as to better accommodate the display module 30 and the support plate 40.

Referring to fig. 1, 3 and 4, fig. 4 is a schematic structural view illustrating the display module 30 and the supporting plate 40 of the embodiment shown in fig. 3. The display module 30 may be a flexible display screen, which has a bendable characteristic, and thus can be bent or flattened.

The display module 30 is disposed on the support plate 40 to be supported. The display module 30 may include a curved display portion 31 disposed corresponding to the first housing 10, a flat display portion 32 disposed corresponding to at least the first housing 10 and connected to the curved display portion 31, a movable bending portion 33 disposed corresponding to the second housing 20, such as the roller 21, and connected to the flat display portion 32, and a hiding portion 34 received in the second housing 20 and connected to the movable bending portion 33.

The curved display portion 31 may be formed by bending the edge of the flat display portion 32 to one side of the supporting plate 40, so that the curved display portion 31 has a curved display surface, and the curved screen type electronic device 100 may be formed. The flat display portion 32 may have a display surface in a plane. When the first housing 10 and the second housing 20 are in the folded state, the flat display portion 32 may be disposed only corresponding to the first housing 10, but in some scenarios, the flat display portion 32 may be disposed partially corresponding to the first housing 10 and partially corresponding to the second housing 20. When the first and

second casings

10 and 20 are unfolded, the supporting surface of the supporting plate 40 is gradually increased corresponding to the second casing 20 to support more of the flattened display part 32. That is, when the first and

second casings

10 and 20 are unfolded, the number of portions of the flat display portion 32 exposed to the outside increases. The moving curved portion 33 may be formed by bending the display module 30 and may further be formed corresponding to the curved surface of the roller 21, such that the moving curved portion 33 is partially exposed and the moving curved portion 33 is partially received in the second housing 20. The exposed portion of the movable bending portion 33 may have a curved display surface as the curved display portion 31, and may further cooperate with the curved display portion 31 to form the curved screen-type electronic device 100. The hiding portion 34 is formed by bending the display module 30, and is shielded and stored in the second housing 20 based on the engagement of the moving bending portion 33 and the roller 21.

It can be understood that when the first casing 10 and the second casing 20 slide relatively, the hiding portion 34 may slide out of the second casing 20 to increase the display area of the flat display portion 32, and the flat display portion 32 may slide into the second casing 20 to decrease the display area of the flat display portion 32.

In addition, the moving curved portion 33 may be changed as the first and

second housings

10 and 20 slide relative to each other.

Moreover, the movable bending portion 33 can move together with the roller 21 when the roller 21 rotates, and can also slide on the roller 21, so that the portion of the display module 30 corresponding to the roller 21 can slide and bend to form the movable bending portion 33 based on the bending characteristics of the display module 30, and further, the movable bending portion 33 can slide into the second housing 20 to become a part of the hidden portion 34, and can slide out of the second housing 20 to become a part of the flat display portion 32. It is understood that the movable bending portion 33 and the hiding portion 34 may form the movable display portion 301, and of course, the structure of the movable display portion 301 is not limited to the movable bending portion 33 and the hiding portion 34, but may include other structures.

The display module 30 further includes a flexible circuit board 35 electrically connected to the curved display portion 31. The flexible circuit board 35 may be located on a non-display side of the display module 30. The flexible circuit board 35 may be disposed at least on a side of the supporting board 40 away from the display module 30 by attaching, fixing, and the like. In some scenarios, the flexible circuit board 35 may be partially disposed on the curved display portion 31 and/or the flat display portion 32, and the support plate 40 may be provided with a perforation and/or a notch at the corresponding portion to give way to the flexible circuit board 35.

One end of the flexible circuit board 35 may be electrically connected to the wire outlet of the curved display portion 31 and may be electrically connected to the circuit board in the housing assembly 200, so as to control the display module 30. The flexible circuit board 35 is bendable, and can be further bent to the non-display side of the display module 30. So that the bent portion 351 is formed at the side circumferential surface of the support plate 40.

Referring to fig. 3, fig. 4 and fig. 5, fig. 5 is a schematic perspective view illustrating the display module 30 and the supporting plate 40 of the embodiment shown in fig. 4. The supporting plate 40 may be disposed on the first housing 10 and the second housing 20, and stacked with the display module 30, so as to support the display module 30, so as to ensure the flatness of the display module 30, such as the flat display portion 32, and the curvature of the display module 30, such as the curved display portion 31 and the moving curved portion 33.

The supporting plate 40 can be used as a supporting surface corresponding to the display module 30, such as the curved display portion 31 and the flat display portion 32. The exposed part of the supporting plate 40 corresponding to the roller 21 can also be used as a part of the supporting surface. The supporting plate 40 may have a bending characteristic at least partially so as to be bent at a portion corresponding to the roller 21, and is shielded and received in the second housing 20. When the first housing 10 and the second housing 20 slide relatively, the support plate 40 can be at least partially folded at the roller 21 to be shielded and received in the second housing 20.

The supporting plate 40 may include a flexible supporting layer 41 stacked on the display module 30 and bendable or flatted together with the display module 30, a supporting reinforcing layer 42 stacked on the flexible supporting layer 41 and located on a side of the flexible supporting layer 41 far away from the display module 30, and a glue layer 43 disposed between the flexible supporting layer 41 and the display module 30.

The flexible supporting layer 41 can ensure the bending characteristic of the display module 30, can avoid excessive bending of the display module 30, and can also reduce the probability that the display module 30 is directly arranged on the supporting and reinforcing layer 42 to have poor flatness, poor curvature and other problems. That is, the flexible supporting layer 41 can reinforce the strength of the display module 30 without affecting the bending characteristics of the display module 30 too much. The supporting reinforcing layer 42 can further support the display module 30, and at least has a bendable characteristic at a position corresponding to the roller 21, so as to ensure the flatness of the display module 30, such as the flat display portion 32, and the curvature of the display module 30, such as the curved display portion 31 and the moving curved portion 33.

The flexible supporting layer 41 may be made of a metal material with high hardness and strength or a non-metal material with high hardness and strength, and is not particularly limited, and only the flexible supporting layer 41 can be bent and flattened by the hardness and strength. The flexible support layer 41 may be a rectangular sheet-like structure. Of course, in other embodiments, the flexible support layer 41 may have other structural configurations. In some embodiments, the flexible support layer 41 is disposed in a grid. For example, the flexible support layer 41 may be punched out of a single sheet of steel to form a grid-like structure.

The flexible support layer 41 can be bent in a direction in which the first housing 10 and the second housing 20 slide relative to each other. For example, the display module 30 is bent at a portion corresponding to the curved display section 31. For example, at a portion corresponding to the roller 21. In some embodiments, the flexible supporting layer 41 may have elasticity and thus be flattened at a portion corresponding to the display module 30, such as the flattened display portion 32, so as to ensure the flatness of the display module 30.

Referring to fig. 4 and 5, the supporting and reinforcing layer 42 may include a flexible supporting member 421, a planar supporting member 422 and a bending supporting member 423 disposed in the same layer and stacked on the flexible supporting layer 41, respectively. The flexible support 421, the plane support 422 and the bending support 423 cooperatively support the flexible support layer 41.

The flexible supporting member 421 can be bent in a direction in which the first housing 10 and the second housing 20 slide relative to each other, so as to be bent or spread together with the flexible supporting layer 41. When the flexible support 421 is unfolded, the planar support 422 is located between the flexible support 421 and the bending support 423. When the flexible supporting member 421 is bent, the flexible supporting member 421 can be bent to be at least partially stacked on the planar supporting member 422. The flexible supporting member 421 may be disposed corresponding to the roller 21, so that the flexible supporting member 421 and the flexible supporting layer 41 can be bent and slid on the roller 21, and can be flattened on the supporting surface for supporting. In one embodiment, a portion of the flexible supporting member 421 corresponding to the roller 21 is bent to contact with the surface of the roller 21 and support the flexible supporting layer 41 and the display module 30.

The planar support 422 may be used to support the flexible support layer 41 to maintain local flatness of the flexible support layer 41. The bending support 423 is disposed corresponding to the display module 30, such as the curved display portion 31, so as to support the display module 30, such as the curved display portion 31, and form the curved-screen electronic device 100.

Referring to fig. 4, 5 and 6, fig. 6 is a schematic structural view of a portion a of the display module 30 and the supporting plate 40 in the embodiment shown in fig. 5. The flexible support 421 may include a plurality of strip-shaped support members 4211 arranged in a sliding direction of the first casing 10 relative to the second casing 20. Two adjacent strip-shaped support members 4211 may be disposed at an interval so as to give way for bending the flexible support layer 41, so that the flexible support layer 41 and the display module 30, such as the moving bending portion 33, can be bent. The bar-shaped support members 4211 may be extended in a direction perpendicular to the bending direction of the flexible support 421. In some embodiments, a plurality of bar support members 4211 may be uniformly distributed. In some embodiments, the plurality of strip support members 4211 may be secured to the flexible support layer 41 by bonding or the like.

In some embodiments, the material of the strip 4211 is hard plastic, metal or alloy material. In some scenarios, the material of the strip support members 4211 may be stainless steel.

Referring to fig. 7, fig. 7 is a schematic structural diagram of the flexible supporting member 421 in the embodiment shown in fig. 6. The flexible support 421 further includes a flexible body 4212 disposed between two adjacent strip-shaped support members 4211. Two adjacent strip-shaped support members 4211 are connected by a flexible body 4212.

Two adjacent strip-shaped support members 4211 are connected through a flexible body 4212 to keep the stability of the relative position between the two adjacent strip-shaped support members 4211, so that the risks of dislocation, tilting and the like of the flexible display screen when the corresponding roller 21 is bent by the flexible support member 421 are reduced. In addition, the resistance of the electronic device 100 in the processes of unfolding and folding movements is reduced, the risks of jamming and the like of the electronic device 100 are greatly reduced, and the service life of the motor for driving the roller 21 to rotate is indirectly prolonged.

The material of the flexible body 4212 may have a hardness less than that of the strip support members 4211. In one embodiment, the flexible body 4212 may be made of flexible resin, such as silicone rubber, TPU (Thermoplastic polyurethane elastomer), and the like. In one embodiment, the flexible body 4212 may be a strip structure and may extend in the extending direction of the strip support member 4211.

The connection position of the flexible body 4212 and the strip support members 4211 may be a central position of the strip support members 4211 in the stacking direction of the support plates 40.

Referring to fig. 8, fig. 8 is a schematic structural view of the flexible supporting member 421 shown in fig. 6 according to another embodiment. The connection position of the flexible body 4212 and the strip-shaped support member 4211 may be a position of the strip-shaped support member 4211 near the flexible support layer 41 in the stacking direction of the support plate 40. In some embodiments, flexible body 4212 may be a rectangular structure.

In some embodiments, referring to fig. 9, fig. 9 is a schematic structural diagram of a flexible supporting member 421 in yet another embodiment of the embodiment shown in fig. 6. The surface of the side of the flexible body 4212 remote from the flexible support layer 41 may be curved. The specific curved surface may be formed by a recess of the flexible body 4212 towards one side of the flexible support layer 41.

Referring to fig. 4 and 5 again, the plane supporting member 422 may be a plate-shaped structure having a flat surface. The planar support 422 may be a rigid plastic, metal, or alloy material. In some scenarios, the material of the planar support 422 may be stainless steel.

The plane supporting member 422 may be at least disposed corresponding to the first housing 10, so as to ensure the flatness of the flexible supporting layer 41 and the display module 30. In one embodiment, the planar support 422 may be connected with the bending support 423. In some embodiments, the planar support 422 may be connected with the flexible support 421. In some embodiments, the planar support 422 is disposed on the first housing 10.

In one embodiment, since the first casing 10 may have a flat surface, the plane support 422 may be a carbon fiber plate made of carbon fiber. In one embodiment, in some embodiments, the carbon fiber plates are provided with thermosetting resin, and the carbon fiber plates can be connected with the bending support 423 by using the thermosetting resin in the carbon fiber plates in the thermoplastic molding, can be connected with the flexible support layer 41 by using the thermosetting resin in the carbon fiber plates in the thermoplastic molding, and can be connected with the flexible support 421 by using the thermosetting resin in the carbon fiber plates in the thermoplastic molding.

Referring again to fig. 4 and 5, the bending support 423 is disposed corresponding to an edge of the flexible support layer 41. The bending support 423 is bent towards a side away from the flexible support layer 41 so as to correspond to the bending display portion 31, and further, the bending shape of the bending support 423 realizes the bending display portion 31 towards a curved surface which is bent towards a side close to the flexible support layer 41, so as to form the curved screen type electronic device 100.

The bending support 423 may be a hard plastic, metal, or alloy material. In some scenarios, the material of the planar support 422 may be stainless steel. The bending supporter 423 may have a plate-shaped structure. The bending support 423 includes a first laminated portion 4231 and a second laminated portion 4232 laminated and bent together toward a side away from the flexible support layer 41, and a bent portion 4233 connecting the first laminated portion 4231 and the second laminated portion 4232. The bent shapes of the first stacked portion 4231 and the second stacked portion 4232 realize a curved surface in which the curved display portion 31 is bent toward the side close to the flexible support layer 41, thereby forming the curved-surface-screen-type electronic device 100. The first laminate 4231 is laminated with the flexible support layer 41, and the second laminate 4232 is located on a side of the first laminate 4231 away from the flexible support layer 41. The bent portions 4233 are connected to end surfaces of the first layered portion 4231 and the second layered portion 4232 on the side of the bent portion 351. The end surfaces of the first layered portion 4231 and the second layered portion 4232 on the side of the bent portion 351 can be prevented from damaging the electronic apparatus 100 by the bent portions 4233. For example, the end surfaces of the first and second

stacked portions

4231 and 4232 facing the curved portion 351 can be prevented from cutting the flexible circuit board 35, thereby ensuring the electrical connection reliability of the display module 30.

In one embodiment, a surface of the bent portion 4233 on a side away from the first stacked portion 4231 and the second stacked portion 4232 is a curved surface, and the flexible circuit board 35, such as the bent portion 351, is cut.

In one embodiment, the bending supporter 423 may be formed by bending the material of the plate-shaped structure by 180 °.
