Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of an electronic device in an unfolded state according to an embodiment of the present application, fig. 2 is a front view of the electronic device in the embodiment shown in fig. 1, and fig. 3 is a schematic sectional view 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 with the first housing 10, a display module 30 disposed on the first housing 10 and the second housing 20, and a support plate 40 disposed between the display module 30 and the first housing 10 and the second housing 20, respectively, to support the display module 30. The first casing 10 and the second casing 20 are relatively slid to change the overall volume of the electronic device 100. The support plate 40 is disposed on the first and second cases 10 and 20 to form a support surface on the first and second cases 10 and 20 to support the display module 30. The size of the area of the support surface may be changed when the first housing 10 and the second housing 20 slide relatively. The display module 30 may be at least partially disposed on the supporting surface, and further supported by the supporting plate 40, so as to change the size of the exposed portion when the size 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 support plate 40, and is a display surface on a side far from the support plate 40, so as to display information on the display surface.
It is understood that in some embodiments, the first housing 10, the second housing 20 and the support plate 40 may form the housing assembly 200, and of course, the housing assembly 200 may not be limited to the first housing 10, the second housing 20 and the support plate 40, but may include other structures. The supporting surface may be a surface of the supporting plate 40 of the housing assembly 200 exposed outside on the side where the display module 30 is disposed. In some embodiments, the display module 30 and the support plate 40 may form the display assembly 300, and of course, the display assembly 300 may be not limited to the display module 30 and the support plate 40, but may include other structures.
Furthermore, the terms "first," "second," "third," and the like in this disclosure are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying a number of technical features being indicated. Thus, a feature defining "a first", "a second", "a third", etc. may include at least one such feature, either explicitly or implicitly.
Referring to fig. 1, 2 and 3, the first housing 10 and the second housing 20 may be made of rigid materials, and the materials may be the same or different. The first casing 10 and the second casing 20 may be made of one or more materials. The first casing 10 is slidably connected with the second casing 20 to form an integral casing of the electronic device 100. The first housing 10 and the second housing 20 cooperate to carry and mount electronic components such as a circuit board (on which a control unit such as a processor or the like is provided), a battery, a camera, a sensor, and the like, and may also carry the support plate 40 and may also house portions of the display assembly 300.
The first casing 10 and the second casing 20 can be in sliding connection through a matching relationship between a sliding rail and a sliding block, a matching relationship between a telescopic structure and the like. Of course, the sliding connection can be realized in other ways, and details are not described.
The first casing 10 and the second casing 20 are slidable with respect to each other such that the first casing 10 and the second casing 20 overlap each other, changing the overall volume of the electronic device 100. The first casing 10 and the second casing 20 can be in a folded state by increasing the overlapping portion. The first casing 10 and the second casing 20 may be in a 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 may also partially slide 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 may be in a folded state by the second casing 20 being enlarged at a portion inside the first casing 10. The first casing 10 and the second casing 20 may be in a unfolded state by a portion of the second casing 20 within the first casing 10 being reduced. That is, the second housing 20 is slidable with respect to the first housing 10 to slide into the first housing 10 to be in a folded state, and to slide out of the first housing 10 to be in an unfolded state.
The second housing 20 internally provides rollers 21 for supporting the support plate 40. The axial direction of the roller 21 may be perpendicular to the sliding direction of the first housing 10 and the second housing 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 diagram of the display module 30 and the support plate 40 in the embodiment shown in fig. 3. The display module 30 may be a flexible display screen, and has a bendable property, so as to be bendable 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 flattened display portion 32 disposed at least corresponding to the first housing 10 and connected to the curved display portion 31, a movable curved portion 33 disposed corresponding to the second housing 20, e.g., the roller 21, and connected to the flattened display portion 32, and a hidden portion 34 housed in the second housing 20 and connected to the movable curved portion 33.
The curved display portion 31 may be formed by bending an edge of the flattened display portion 32 toward one side of the support 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 flattened display portion 32 may have a display surface that is planar. When the first housing 10 and the second housing 20 are in the collapsed state, the flattened display portion 32 may be disposed only corresponding to the first housing 10, but in some cases, the flattened display portion 32 may be disposed partially corresponding to the first housing 10 and partially corresponding to the second housing 20. As the first and second housings 10 and 20 are unfolded, the portion of the support surface of the support plate 40 corresponding to the second housing 20 is gradually increased to support more of the flattened display portion 32. That is, when the first casing 10 and the second casing 20 are unfolded, the exposed portions of the flat display portion 32 are increased. The movable bending 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, so that a portion of the movable bending portion 33 is exposed, and a portion of the movable bending portion 33 is received in the second housing 20. The exposed portion of the movable bending portion 33 may have a curved display surface like the curved display portion 31, and may be matched with the curved display portion 31 to form the curved screen type electronic device 100. The hidden portion 34 is formed by bending the display module 30, and is shielded and accommodated in the second housing 20 by the engagement of the movable curved portion 33 and the roller 21.
It can be appreciated that when the first housing 10 and the second housing 20 slide relatively, the hidden portion 34 can be made to slide out of the second housing 20 to increase the display area of the flattened display portion 32, and the flattened display portion 32 can also be made to slide into the second housing 20 to reduce the display area of the flattened display portion 32.
In addition, the moving bending portion 33 may be changed as the first housing 10 and the second housing 20 relatively slide.
Moreover, the moving curved portion 33 can move together 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 is slidably bent to form the moving curved portion 33 based on the bending characteristic of the display module 30, and further, the moving curved portion 33 can slide into the second housing 20 to form a part of the hidden portion 34, and can also slide out of the second housing 20 to form a part of the flattened display portion 32. It is understood that the movable curved portion 33 and the hidden 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 curved portion 33 and the hidden portion 34, but may include other structures.
The display module 30 further includes a flexible circuit board 35 electrically connected to the curved display section 31. The flexible circuit board 35 may be located on a side of the display module 30 other than the display surface. The flexible circuit board 35 may be disposed on a side of the support plate 40 away from the display module 30 at least by attaching, fixing, or the like. In some scenarios, the flexible circuit board 35 may be partially disposed on the curved display portion 31 and/or the flattened display portion 32, and the support plate 40 may further be provided with perforations and/or indentations at corresponding portions to yield the flexible circuit board 35.
One end of the flexible circuit board 35 may be electrically connected to the wire outlet end 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 has flexibility and can be further bent to the non-display surface side of the display module 30. To form a curved portion 351 at a 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 cooperation between the display module 30 and the support plate 40 in the embodiment shown in fig. 4. The support 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, to ensure flatness of the display module 30, such as the flattened display portion 32, and to ensure curvedness of the display module 30, such as the curved display portion 31 and the movable curved portion 33.
The portion of the support plate 40 corresponding to the display module 30, such as the curved display portion 31 and the flattened display portion 32, may be used as a support surface. The exposed portion of the support plate 40 corresponding to the roller 21 may also be used as a part of the support surface. The support plate 40 may have a bending property at least partially so as to be bent at a portion corresponding to the roller 21, and be shielded and accommodated in the second housing 20. When the first casing 10 and the second casing 20 slide relatively, the support plate 40 may be at least partially folded at the roller 21 and be blocked and received in the second casing 20.
The support plate 40 may include a flexible support layer 41 stacked with the display module 30 and bendable or flattened together with the display module 30, a support reinforcing layer 42 stacked with the flexible support layer 41 and located at a side of the flexible support layer 41 away from the display module 30, and a glue layer 43 disposed between the flexible support layer 41 and the display module 30.
The flexible supporting layer 41 can ensure the bending property of the display module 30, avoid excessive bending of the display module 30, and reduce the probability of poor flatness, poor camber and other problems caused by the direct arrangement of the display module 30 on the supporting reinforcing layer 42. That is, the flexible supporting layer 41 can reinforce the strength of the display module 30 without excessively affecting the bending characteristics of the display module 30. The supporting reinforcement layer 42 can further support the display module 30, and has a bendable property at least at a portion corresponding to the roller 21, so as to ensure flatness of the display module 30, such as the flattened display portion 32, and to ensure curvedness of the display module 30, such as the curved display portion 31 and the movable curved portion 33.
The flexible supporting layer 41 may be made of a metal material with high hardness and strength or a nonmetal material with high hardness and strength, which is not particularly limited, and only needs to have the hardness and strength to bend and flatten the flexible supporting layer 41. The flexible support layer 41 may have a rectangular sheet-like structure. Of course, in other embodiments, the flexible support layer 41 may have other configurations. In some embodiments, the flexible support layer 41 is disposed in a grid-like configuration. For example, flexible support layer 41 may be machined from a single sheet of steel to form a punched hole to form a grid-like structure.
The flexible supporting layer 41 may 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 portion 31. For example, the roller 21 is bent at a position corresponding to the roller. In some embodiments, the flexible supporting layer 41 may have elasticity, and further be flattened at a location corresponding to the display module 30, for example, the flattened display portion 32, so as to ensure the flatness of the display module 30.
Referring to fig. 4 and 5 together, the support reinforcing layer 42 may include a flexible support 421, a planar support 422 and a bending support 423 disposed on the same layer and stacked with the flexible support layer 41, respectively. The flexible supporting member 421, the flat supporting member 422, and the bending supporting member 423 cooperate to support the flexible supporting layer 41.
The flexible support 421 may be bent in a direction in which the first case 10 and the second case 20 slide with respect to each other so as to be bent or unfolded together with the flexible support 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 may be bent to be at least partially stacked with 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 bend and slide on the roller 21, and can be flattened on the supporting surface for supporting. In an embodiment, the portion of the flexible supporting member 421 corresponding to the roller 21 is bent to contact with the surface of the roller 21 to 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 the local flatness of the flexible support layer 41. The bending support 423 is disposed corresponding to the display module 30, for example, the bending display part 31, so as to support the display module 30, for example, the bending display part 31, to form the curved screen type 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 in the embodiment shown in fig. 5 when being matched with the supporting plate 40. The flexible support 421 may include a plurality of bar-shaped support members 4211 arranged in a relative sliding direction of the first housing 10 and the second housing 20. The two adjacent bar-shaped supporting members 4211 may be disposed at intervals, so as to bend the flexible supporting layer 41 to give way, so that the flexible supporting layer 41 and the display module 30, for example, the moving bending portion 33 may bend. The bar-shaped supporting member 4211 may be extended in a direction perpendicular to the bending direction of the flexible supporting piece 421. In some embodiments, a plurality of bar-shaped support members 4211 may be uniformly arranged. In some embodiments, the plurality of bar-shaped support members 4211 may be fixed to the flexible support layer 41 by means of adhesion or the like.
In some embodiments, the bar-shaped support member 4211 is made of a hard plastic, metal or alloy material. In some cases, the material of the bar-shaped supporting member 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 comprises a flexible body 4212 arranged between two adjacent strip-shaped support members 4211. Adjacent two bar-shaped support members 4211 are connected by a flexible body 4212.
The two adjacent strip-shaped supporting members 4211 are connected through the flexible body 4212 so as to keep the relative positions of the two adjacent strip-shaped supporting members 4211 stable, and further reduce risks of dislocation, tilting and the like of the flexible display screen, which occur when the corresponding roller 21 bends, of the flexible supporting piece 421. In addition, the resistance of the electronic device 100 in the unfolding and folding movement process is reduced, risks such as jamming and dead jamming 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 hardness of the material of the flexible body 4212 may be less than the hardness of the material of the bar-shaped supporting member 4211. In one embodiment, the flexible body 4212 may be made of flexible resin, such as silica gel, rubber, TPU (Thermoplastic Polyurethanes, thermoplastic polyurethane elastomer), etc. In one embodiment, the flexible body 4212 may be a bar-shaped structure and may extend in the extending direction of the bar-shaped support member 4211.
The connection position of the flexible body 4212 and the bar-shaped support member 4211 may be a middle position of the bar-shaped support member 4211 in the stacking direction of the support plates 40.
Referring to fig. 8, fig. 8 is a schematic structural diagram of the flexible supporting member 421 in another embodiment in the embodiment shown in fig. 6. The connection position between the flexible body 4212 and the bar-shaped support member 4211 may be a position of the bar-shaped support member 4211 near the flexible support layer 41 in the stacking direction of the support plate 40. In some embodiments, the flexible body 4212 may be rectangular in structure.
In some embodiments, referring to fig. 9, fig. 9 is a schematic structural view of the flexible support 421 in another embodiment of the embodiment shown in fig. 6. The surface of the flexible body 4212 on the side remote from the flexible support layer 41 may be curved. The specific curved surface may be formed by a depression of the flexible body 4212 toward the flexible support layer 41 side.
Referring again to fig. 4 and 5, the planar support 422 may be generally plate-like in configuration with a flat surface. The planar support 422 may be a rigid plastic, metal, or alloy material. In some scenarios, the planar support 422 may be stainless steel.
The planar supporting member 422 may be disposed at least 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 to the bending support 423. In some embodiments, planar support 422 may be connected to flexible support 421. In some embodiments, the planar support 422 is disposed on the first housing 10.
In one embodiment, since the first housing 10 may have a flat surface, the planar support 422 may be a carbon fiber plate made of carbon fibers. In some embodiments, the carbon fiber plate is provided with a thermosetting resin, and the carbon fiber plate may be connected to the bending support member 423 during the thermoplastic molding process by using the thermosetting resin in the carbon fiber plate, the carbon fiber plate may be connected to the flexible support layer 41 during the thermoplastic molding process by using the thermosetting resin in the carbon fiber plate, and the carbon fiber plate may be connected to the flexible support member 421 during the thermoplastic molding process by using the thermosetting resin in the carbon fiber plate.
Referring to fig. 4 and 5 again, the bending support 423 is disposed corresponding to the edge of the flexible support layer 41. The bending support piece 423 is bent towards a side far away from the flexible support layer 41 so as to be arranged corresponding to the bending display portion 31, and further, the bending display portion 31 is bent towards a side close to the flexible support layer 41 through the bending shape of the bending support piece 423, so that the curved surface of the curved surface screen type electronic device 100 is formed.
The bending support 423 may be a rigid plastic, metal, or alloy material. In some scenarios, the planar support 422 may be stainless steel. The bending support 423 may have a plate-like structure.
