In the following description, for the purpose of explanation, details are set forth. It is apparent to those skilled in the art that the present application can be practiced without using these specific details. In other instances, well-known structures and processes are not described in detail in order to avoid obscuring the description of the present application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.

[0062] With the rapid development of screen display technology, various display devices can be seen everywhere in life, such as common liquid crystal televisions and liquid crystal displays. However, these display devices have a large screen size, thus occupying a large space and being inconvenient to carry.

[0063] A curling display device is provided in the related art, which comprises a flexible screen, a lifting mechanism connected to a top end of the flexible screen, and a screen winding mechanism connected to a bottom end of the flexible screen; the lifting mechanism is used to drive the flexible screen to ascend or descend; the flexible screen is used to unfold the flexible display screen when the lifting mechanism drives the flexible display screen to ascend, or wind up the flexible screen when the lifting mechanism drives the flexible screen to descend. Although this scheme solves the problem of large space occupied by the display screen to some extent, the curling display device cannot realize double-sided display, which affects the user's visual experience; the flexible screen and the lifting mechanism need to be fixedly connected, the connection stability of the screen is poor, the screen is easy to be damaged, and the replacement cost is high.

[0064] Therefore, the present application provides a novel display device, which comprises a housing, a screen winding drum, a lifting mechanism, and a flexible screen module; the housing is provided with a mounting cavity, and a first opening is arranged on the housing and communicates with the mounting cavity; the flexible screen module comprises a flexible screen, the flexible screen is connected with the screen winding drum, and along the thickness direction of the flexible screen, the flexible screen comprises a display side and a non-display side arranged oppositely; the lifting mechanism is arranged in the mounting cavity, and is configured to abut against the non-display side and drive the flexible screen to enter or exit the mounting cavity through the first opening; during the process that the lifting mechanism drives the flexible screen, the flexible screen moves relative to the lifting mechanism to change the length of the part of the flexible screen located on both sides of the lifting mechanism; and the screen winding drum is rotatably arranged in the mounting cavity and is configured to release the flexible screen when the lifting mechanism drives the flexible screen to move out of the mounting cavity and wind up the flexible screen when the lifting mechanism drives the flexible screen to move into the mounting cavity. The lifting mechanism abuts against the non-display side and drives the flexible screen to enter or exit the mounting cavity through the first opening, and the screen winding drum realizes the function of winding up the flexible screen, thereby solving the problem of large space occupied by the display screen. During the process that the lifting mechanism drives the flexible screen, the length of the part of the flexible screen located on both sides of the lifting mechanism is changed by the movement of the flexible screen relative to the lifting mechanism, so that the size of the display surface on each side of the lifting mechanism can be flexibly changed, double-sided display is realized, and in addition, in this scheme, the connection of the flexible screen is stable, and the flexible screen is not easy to be damaged and worn, thereby reducing the maintenance cost.

[0065] For the convenience of understanding, the present application will be further described in combination with specific embodiments and drawings.

[0066] Referring to FIGS. 1-3, the display device 1000 includes a housing 100, a screen winding roller 410, a flexible screen module 600, and a lifting mechanism 200. The flexible screen module 600 includes a flexible screen 611 connected to the screen winding roller 410. The housing 100 is configured to provide a mounting space and protect components inside the housing 100. The flexible screen 611 is configured to display information. The lifting mechanism 200 is configured to drive the flexible screen 611 to extend or retract in a predetermined direction. The screen winding roller 410 is configured to wind or release the flexible screen 611.

[0067] In the embodiment, referring to FIGS. 1 and 5, the housing 100 includes a first opening 161, and the housing 100 includes a mounting cavity 110. The mounting cavity 110 is configured to accommodate the flexible screen module 600, the lifting mechanism 200, the screen winding roller 410, and the like. The lifting mechanism 200 and the flexible screen 611 can enter or exit the mounting cavity 110 through the first opening 161.

[0068] It should be noted that the shape of the housing 100 and the material for manufacturing the housing 100 are not limited in the present application. For example, the material for manufacturing the housing 100 can be a metal material, an alloy (e.g., an aluminum alloy) material, a plastic (e.g., polycarbonate), a glass material, a fiber composite material, or the like. The shape of the housing 100 can be a cuboid, a cylinder, a sphere, a polygonal prism, or the like. In the following description, the housing 100 is taken as an example of a cuboid unless otherwise specified.

[0069] In the embodiment, referring to FIG. 1, the housing 100 is a cuboid, and the housing 100 includes a front panel 10, a rear panel 13, a left panel 14, a right panel 15, a top panel 16, and a bottom panel 17. The front panel 10 and the rear panel 13 are arranged opposite to each other along the width direction of the housing 100, the top panel 16 and the bottom panel 17 are arranged opposite to each other along the height direction of the housing 100, and the left panel 14 and the right panel 15 are arranged opposite to each other along the length direction of the housing 100. The front panel 10, the rear panel 13, the left panel 14, the right panel 15, the top panel 16, and the bottom panel 17 jointly form the mounting cavity 110. For the convenience of description, the length direction of the housing 100 is defined as the X-axis direction, the width direction of the housing 100 is defined as the Y-axis direction, and the height direction of the housing 100 is defined as the Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0070] Optionally, referring to FIG. 1 and FIG. 2, the front panel 10 is provided with a light outlet hole 11b near one end of the bottom panel 17, and the front panel 10 is provided with a light source mounting groove 12b in communication with the light outlet hole 11b, the light source mounting groove 12b comprises a first inclined surface 122, the first inclined surface 122 is arranged opposite to the light outlet hole 11b, one end of the first inclined surface 122 extends to the light outlet hole 11b near the bottom panel 17, the other end of the first inclined surface 122 extends towards the inside of the front panel 10 (i.e. the direction of the front panel close to the back panel), and the first inclined surface 122 covers the light outlet hole 11b in the orthographic projection of the plane on which the light outlet hole 11b is located.

[0071] Thus, when the light source (such as LED light bar) in the light source mounting groove 12b emits light, the light emitted by the light source can be reflected by the first inclined surface 122 and then emitted through the light outlet hole 11b on the front panel 10, thereby increasing the light effect of the display device 1000 in the present application. In addition, since the first inclined surface 122 covers the light outlet hole 11b in the orthographic projection of the plane on which the light outlet hole 11b is located, the first inclined surface 122 can block the light outlet hole 11b from the inside, thereby avoiding the structure inside the shell 100 from being exposed in the light outlet hole 11b, and further improving the appearance quality of the display device 1000 in the present application.

[0072] Exemplarily, the sound emitted by the player in the shell 100 can also be propagated outward through the light outlet hole 11b, which is beneficial to improve the sound effect of the display device 1000 in the present application.

[0073] Exemplarily, the bottom panel 17 and the front panel 10 are arranged vertically. Referring to FIG. 1 and FIG. 2, the light outlet hole 11b is generally in the shape of a narrow strip, and the two ends of the light outlet hole 11b in the length direction (i.e. the X-axis direction) extend to near the left panel 14 and the right panel 15, respectively.

[0074] In some embodiments of the present application, referring to FIG. 2, the front panel 10 is provided with a second opening 11a, and the front panel 10 is provided with a first accommodating groove 12a which is in communication with the second opening 11a. The first accommodating groove 12a is used to accommodate the shielding plate 310 of the shielding plate mechanism. Specifically, the shielding plate 310 has a shielding position (as shown in FIGS. 1 and 2) for shielding the second opening 11a, and a retreat position for opening the second opening 11a and being accommodated in the first accommodating groove 12a. In one use scenario of the present application, the camera module is exposed in the second opening 11a, and when the second opening 11a is opened, the camera module can obtain external environment information through the camera. When privacy needs to be improved, the shielding plate 310 is switched from the retreat position to the shielding position under the driving action, so that the shielding plate 310 blocks the camera of the camera module, so that the blocked camera cannot obtain external environment information. The structure is conducive to improving the application scenarios of the display device 1000 in the present application and improving the appearance quality.

[0075] Optionally, referring to FIG. 2, the front panel 10 includes a panel body 11 and a front support plate 12. The front support plate 12 is fixedly connected with the bottom panel 17. The panel body 11 is fixed on the outer side of the front support plate 12 (i.e., the side of the front support plate 12 away from the mounting cavity 110). A light source mounting groove 12b is arranged between the front support plate 12 and the panel body 11, and the light source mounting groove 12b is arranged close to the bottom panel 17. The first accommodating groove 12a is arranged between the front support plate 12 and the panel body 11, and the first accommodating groove 12a is arranged close to the top panel 16. In this way, it is conducive to improving the storage performance of the display device 1000 in the present application.

[0076] Specifically, referring to FIGS. 9-12, the front support plate 12 has a generally rectangular orthographic projection (i.e., a projection on the plane formed by the X-axis and the Z-axis). The front support plate 12 is arranged at one end of the bottom panel 17 away from the rear panel 13. The plane on which the front support plate 12 is arranged is generally perpendicular to the plane on which the bottom panel 17 is arranged. The bottom surface of the front support plate 12 (i.e., the surface of the front support plate 12 facing the bottom panel 17) is fixedly connected with the inner side surface of the bottom panel 17 (i.e., the surface of the bottom panel 17 facing the mounting cavity 110), for example, the bottom surface of the front support plate 12 and the inner side surface of the bottom panel 17 are threadedly connected.

[0077] Specifically, referring to FIGS. 2 and 9, the surface of the front support plate 12 facing the panel body 11 is provided with a panel connecting protrusion 121, which extends to the left and right ends of the front support plate 12 along the length direction (i.e., the X-axis direction) of the front support plate 12. The surface of the panel connecting protrusion 121 facing the panel body 11 is fixedly connected with the panel body 11.

[0078] Exemplarily, the panel body 11 is made of glass, the outer side of the panel body 11 (i.e. the side of the panel body 11 away from the mounting cavity 110) forms the front appearance surface of the shell 100, the inner side of the panel body 11 is arranged opposite to the panel connecting protrusion 121, and the inner side of the panel body 11 is adhesively fixed to the side of the panel body 11 opposite to the panel connecting protrusion 121. In this embodiment, since the panel body 11 is made of glass, the inner side of the panel body 11 is adhesively fixed to the panel connecting protrusion 121, thereby avoiding the arrangement of fasteners such as threaded holes on the panel body 11, and being conducive to further improving the appearance quality of the display device 1000 in the present application.

[0105] Optionally, referring to FIGS. 8 and 18, the first support plate 181 is provided with a first mounting hole 1811, and the second support plate 182 is provided with a third mounting hole 1821, the first mounting hole 1811 and the third mounting hole 1821 are used to mount the screen winding roller 410. In this way, the first support plate 181 and the second support plate 182 are arranged in the housing, and the two ends of the screen winding roller 410 with large mass are rotatably connected with the first support plate 181 and the second support plate 182, which is beneficial to improve the stability of the display device. In addition, the first support plate 181 and the second support plate 182 can form a plurality of mounting surfaces in the housing 100, which is beneficial to increase the flexibility of the arrangement of components in the housing 100.

[0106] Specifically, one end of the screen winding roller 410 is rotatably connected with one of the first mounting hole 1811 and the third mounting hole 1821, and the other end of the screen winding roller 410 is rotatably connected with the other one of the first mounting hole 1811 and the third mounting hole 1821, so that the screen winding roller 410 is rotatably arranged in the mounting cavity 110.

[0107] Optionally, referring to FIG. 7, the first support plate 181 is provided with a second mounting hole 1812, and the second support plate 182 is provided with a fourth mounting hole 1822.

[0108] In some embodiments of the present application, the first opening 161 is used for the flexible screen 611 to extend out of the mounting cavity 110 of the shell 100 to be exposed outside the shell 100, so that the user can watch the picture information displayed on the flexible screen 611 exposed outside the shell 100.

[0109] In some embodiments of the present application, referring to FIG. 2, the display device 1000 further comprises a cover plate 700 used to open or close the first opening 161. That is, after the cover plate 700 opens the first opening 161, the flexible screen 611 extends out of the mounting cavity 110 of the shell 100 to be exposed outside the shell 100, so that the user can watch the picture information displayed on the flexible screen 611 exposed outside the shell 100.

[0110] It should be noted that the position and shape of the first opening 161 in the present application are not limited, as long as the inner wall of the first opening 161 does not interfere with the flexible screen 611 when the flexible screen 611 passes through the first opening 161. For example, the first opening 161 is arranged on the top panel 16. The flexible screen 611 extends out of the shell 100 through the first opening 161 to be exposed outside the shell 100. The orthogonal projection of the part of the flexible screen 611 exposed outside the shell 100 on the plane where the first opening 161 is located is generally rectangular, and accordingly, the first opening 161 is generally rectangular. The first opening 161 extends along the X-axis direction, and along the X-axis direction, the size of the first opening 161 is greater than the size of the flexible screen 611. Along the Y-axis direction, the size of the first opening 161 is greater than the size of the flexible screen 611.

[0111] For example, when the flexible screen 611 is working, the flexible screen 611 extends out of the first opening 161 to be exposed outside the shell 100 under the driving action of the lifting mechanism 200. When the flexible screen 611 is not working, the flexible screen 611 is accommodated in the mounting cavity 110 of the shell 100, so that the volume of the display device 1000 is smaller and it is more convenient to carry.

[0112] In the embodiment of the present application, the flexible screen 611 includes a display side and a non-display side arranged oppositely along the thickness direction of the flexible screen 611. It should be noted that the display side is the side of the flexible screen 611 used for displaying information.

[0113] In the embodiment of the present application, the lifting mechanism 200 is arranged in the mounting cavity 110, and is configured to abut against the non-display side to drive the flexible screen 611 to enter or exit the mounting cavity 110 through the first opening 161. During the driving of the flexible screen 611 by the lifting mechanism 200, the flexible screen 611 rolls or slides relative to the lifting mechanism 200 to change the length of the flexible screen 611 located on both sides of the lifting mechanism 200.

[0114] For example, as shown in FIG. 2, one end of the flexible screen 611 in the length direction is fixed in the housing 100 (for example, the one end of the flexible screen 611 is fixedly connected with the screen fixing member 620), and the other end of the flexible screen 611 in the length direction is fixedly connected with the screen winding roller 410 by passing around the lifting mechanism 200 (for example, the non-display side of the flexible screen 611 is carried on the lifting roller 220 of the lifting mechanism 200).

[0115] It can be understood that when the lifting mechanism 200 extends out of the first opening in the lifting direction, the one end of the flexible screen 611 located on the left side of the lifting mechanism 200 is fixedly connected with the screen fixing member 620, the screen winding roller 410 releases the wound flexible screen 611, the flexible screen 611 located on the right side of the lifting mechanism 200 moves relative to the lifting mechanism 200 in the left direction (i.e., the direction close to the front panel 10) under the driving action of the lifting mechanism 200, and the flexible screen 611 moves in the lifting direction and extends out of the first opening 161 under the driving action of the lifting mechanism 200. After the lifting mechanism 200 extends out of the first opening 161, and continues to extend in the direction away from the first opening 161, the sizes of the flexible screens 611 exposed outside the housing through the first opening 161 and located on both sides of the lifting mechanism 200 also gradually increase, so that the display device in the present application realizes double-sided display, and the sizes of the display surfaces on each side of the lifting mechanism 200 can be flexibly changed, which is suitable for more scenes.

[0116] In the embodiment of the present application, the screen winding roller 410 is rotatably arranged in the mounting cavity 110, and is configured to release the flexible screen 611 when the lifting mechanism 200 drives the flexible screen 611 to move out of the mounting cavity 110, and to wind the flexible screen 611 when the flexible screen 611 moves into the mounting cavity 110, that is, the screen winding roller 410 releases the flexible screen 611 when the flexible screen 611 moves out of the mounting cavity 110, so that the flexible screen 611 can be unfolded under the driving action of the lifting mechanism 200. And the screen winding roller 410 winds the flexible screen 611 when the flexible screen 611 moves into the mounting cavity 110. In this way, the flexible screen 611 can be wound on the screen winding roller 410 when not in use, which is beneficial to improve the storage performance of the display device 1000 and improve the structural compactness of the display device.

[0117] Exemplarily, the screen winding roller 410 is arranged along the length direction of the housing 100, and both ends of the screen winding roller 410 are rotatably arranged in the mounting cavity 110 through bearing seats. Specifically, both ends of the screen winding roller 410 are rotatably connected with the first support plate 181 and the second support plate 182 respectively.

[0118] When the display device 1000 needs to display a picture, the screen winding roller 410 releases the wound flexible screen 611, and the lifting mechanism 200 drives the flexible screen 611 to extend out of the housing 100 through the first opening 161 along a preset extension direction (for example, the Z-axis direction). Exemplarily, in this process, the lifting mechanism 200 extends along the Z-axis direction, and the lifting mechanism 200 drives the flexible screen 611 carried thereon to extend out of the first opening 161 along the Z-axis direction to expose the flexible screen 611 outside the housing 100. Similarly, when the flexible screen 611 of the display device 1000 needs to be stored in the mounting cavity 110, the lifting mechanism 200 retracts into the mounting cavity 110 along a preset retracting direction, and the flexible screen 611 follows the lifting mechanism 200 to retract along the preset retracting direction, and in this process, the screen winding roller 410 winds the flexible screen 611 in the unfolded state (that is, the flexible screen 611 extends out of the first opening 161 and is exposed outside the housing 100), so that the flexible screen 611 is wound on the screen winding roller 410. It can be understood that by matching the rotation speed of the screen winding roller 410 with the extension speed of the lifting mechanism 200, the flexible screen 611 can be always tensioned on the lifting mechanism 200 and the screen winding roller 410 during the extension or storage process, which is beneficial to avoid damage to the flexible screen 611 during the extension or storage, and improve the stability of the flexible screen 611.

[0119] In summary, the embodiment of the present application configures the lifting mechanism 200 to abut the non-display side of the flexible screen 611 to drive the flexible screen 611 to enter or exit the installation cavity 110 through the first opening 161, and in the process of driving the flexible screen 611 by the lifting mechanism 200, the flexible screen 611 rolls or slides relative to the lifting mechanism 200 to change the length of the part of the flexible screen 611 located on both sides of the lifting mechanism 200; at the same time, the screen winding roller 410 is rotatably arranged in the installation cavity 110 and is configured to release the flexible screen 611 when the lifting mechanism 200 drives the flexible screen 611 to move out of the installation cavity 110 and wind the flexible screen 611 when the lifting mechanism 200 drives the flexible screen 611 to move into the installation cavity 110. In this way, through the cooperation of the flexible screen 611, the lifting mechanism 200 and the screen winding roller 410, the flexible screen 611 can be moved out of the installation cavity 110 through the first opening 161 to display information when the flexible screen 611 works, and can be wound on the screen winding roller 410 to realize the storage function when the flexible screen 611 does not work. In addition, in the process of driving the flexible screen 611 by the lifting mechanism 200, the length of the part of the flexible screen 611 located on both sides of the lifting mechanism 200 can be freely adjusted, so that the display device in the present application realizes double-sided display, and the size of the display surface on each side of the lifting mechanism 200 can be flexibly changed, which is suitable for more scenes.

[0120] In some embodiments of the present application, the flexible screen 611 has a first fixed part and a second fixed part arranged opposite along the length direction thereof, the first fixed part is connected with the screen winding roller 410, and the second fixed part is fixed in the installation cavity 110.

[0121] Specifically, the first fixed part is fixedly connected with the screen winding roller 410. The second fixed part is fixed in the installation cavity 110 by the screen fixing member 620. In this way, when the flexible screen 611 is not used, the flexible screen 611 can be completely stored in the installation cavity 110, which is beneficial to improve the storage performance of the display device, improve the appearance quality and the stability of the flexible screen 611 in the installation cavity 110.

[0122] Optionally, the flexible screen 611 includes a screen body and a connecting film, and the screen body includes a display side and a non-display side. For example, the screen body can be an OLED flexible screen.

[0123] Exemplarily, the connecting film comprises a first connecting film 6113 and a second connecting film 6112 connected to two ends of the screen body. One of the first connecting film 6113 and the second connecting film 6112 is connected with the screen winding roller 410, and the other of the first connecting film 6113 and the second connecting film 6112 is connected with the screen fixing member 620. This embodiment is advantageous in reducing the size of the screen body, reducing the cost of the flexible screen 611, and avoiding the risk of damage of the screen body under the pulling force of the screen winding roller 410 and / or the screen fixing member 620 by arranging the connecting film, so that the flexible screen 611 is fixedly connected with the screen fixing member 620 and the screen winding roller 410 through the first connecting film 6113 and the second connecting film 6112 respectively.

[0124] Optionally, referring to FIG. 19, the first connecting film 6113 is provided with a first fixing part, and the second connecting film 6112 is provided with a second fixing part. The second fixing part is connected with the screen winding roller 410, and the first fixing part is connected with the screen fixing member 620. Specifically, the first connecting film 6113 is provided with a first fixing part at one end away from the screen body, and the first fixing part is fixedly connected with the screen fixing member 620. The second connecting film 6112 is provided with a second fixing part at one end away from the screen body, and the second fixing part is fixedly connected with the screen winding roller 410.

[0125] Optionally, the screen body and the connecting film are an integral structure. Exemplarily, the screen body is integrally formed on the connecting film or the non-display side of the screen body is fixedly connected with the connecting film so that the screen body and the connecting film are an integral structure. The screen body can only cover the middle part of the connecting film. Along the length direction of the screen body, the two ends of the connecting film not covered by the screen body form the first connecting film 6113 and the second connecting film 6112. One of the first connecting film 6113 and the second connecting film 6112 is connected with the screen winding roller 410, and the other of the first connecting film 6113 and the second connecting film 6112 is connected with the screen fixing member 620. This structure is advantageous in increasing the connecting area between the screen body and the connecting film and improving the acting force between the screen body and the connecting film.

[0126] It can be understood that when the screen body is entirely exposed outside the shell 100 and is located on the display side of the shell 100 (for example, the side on which the front panel 10 is located), the display device 1000 has the largest display size on the side on which the screen body is located, at this time, the connecting film (for example, the connecting film fixedly connected with the screen winding roller 410) is also exposed outside the shell 100, and the connecting film is arranged opposite to the screen body. For example, the screen body faces the side on which the front panel 10 is located, and the connecting film faces the side on which the rear panel 13 is located, and the connecting film can shield the back of the screen body (that is, the side of the screen body away from the front panel 10), thereby improving the aesthetic appearance of the display device 1000. It should be noted that in another embodiment of the present application, the screen body can also cover all the connecting film, which is not limited herein.

[0127] In some embodiments of the present application, the screen body includes a display part 6111, the display part 6111 has a first working state and a second working state when the display part 6111 is stretched out of the mounting cavity 110; in the first working state, the display part 6111 is located on one side of the lifting mechanism 200; in the second working state, there is part of the display part 6111 on both sides of the lifting mechanism 200. The display part 6111 is used to display information.

[0128] It can be understood that when the lifting mechanism 200 is stretched out of the shell 100 through the first opening 161, the part of the screen body close to the screen fixing member is first stretched out of the first opening 161 and exposed outside the shell 100. As the lifting mechanism 200 continues to move in the direction away from the top panel 16, both sides of the display device 1000 have part of the screen body. For example, when the lifting mechanism 200 is stretched out of the top panel 16 by a preset distance through the first opening 161, the display part 6111 of the screen body is entirely exposed outside the shell 100, at this time, the sizes of the display part 6111 on both sides of the lifting mechanism 200 are substantially the same. Thereafter, as the lifting mechanism 200 continues to move in the direction away from the top panel 16, the display part 6111 gradually moves to the side on which the front panel 10 is located, and the connecting film connected with the screen winding roller 410 is stretched out of the shell 100 and exposed on the side on which the rear panel 13 is located. When the lifting mechanism 200 is in a fully stretched state, the distance between the lifting mechanism 200 and the top panel 16 reaches a maximum value, the display part 6111 is entirely moved to the side on which the front panel 10 is located (that is, the display side of the display device 1000), at this time, the side on which the front panel 10 is located has the largest display area, and the connecting film 6112 shields the back of the flexible screen 611 (that is, the side of the flexible screen 611 away from the front panel 10), thereby improving the aesthetic appearance of the display device 1000.

[0129] Exemplarily, in the first working state, as shown in FIG. 3 and FIG. 19, the display part 6111 is located on one side of the lifting mechanism 200, the display device 1000 has the maximum display size on the side, the connecting film 6112 covers the back of the flexible screen 611 (i.e. the side of the flexible screen 611 facing away from the front panel 10), and correspondingly, the lifting mechanism 200 is in the fully stretched state along the preset direction. In the second working state, as shown in FIG. 4, the display size of the display device 1000 on one side is smaller than the maximum display size, and correspondingly, the lifting mechanism 200 is in the not fully stretched state along the preset direction, and the lifting mechanism 200 is in the half stretched state or the half folded state. For the convenience of understanding, it is assumed that when the lifting mechanism 200 is fully stretched, the distance between the lifting mechanism 200 and the top panel 16 is H, at this time, the display part is just moved to one side of the lifting mechanism 200, and the display device 1000 has the maximum display size on the side where the display part is located. When the lifting mechanism 200 is not fully stretched, the distance between the lifting mechanism 200 and the top panel 16 is smaller than H, for example, along the Z-axis direction, the distance between the lifting mechanism 200 and the top panel 16 through the first opening 161 is 1 / 2H or 1 / 3H, at this time, the display part is distributed on both sides of the lifting mechanism 200, that is, the screen body can display information on both sides of the lifting mechanism 200. In this way, by controlling the stroke of the lifting mechanism 200 along the preset stretching direction (for example, the Z-axis direction), the size of the display part 6111 exposed outside the shell 100 and distributed on both sides of the lifting mechanism 200 can be changed, so that the user can flexibly select single display or double display, and when double display, the size of each display surface can be adjusted, thereby being suitable for more use scenarios.

[0130] In some embodiments of the present application, referring to FIG. 2, the flexible screen 611 module further comprises a protective film 612, and the display device 1000 further comprises a film winding roller 420; the film winding roller 420 is configured to release the protective film 612 to cover the display side of the wound flexible screen 611 when the screen winding roller 410 winds the flexible screen 611, and wind the protective film 612 to separate the protective film 612 from the flexible screen 611 when the screen winding roller 410 releases the flexible screen 611. Exemplarily, the protective film 612 is made of soft material, and the protective film 612 is arranged between two adjacent layers of wound flexible screen 611. This embodiment avoids the direct extrusion of the flexible screen 611 when winding due to the existence of foreign matters, and avoids the damage of the display area by arranging the protective film 612.

[0131] In some embodiments of the present application, the film winding roller 420 and the screen winding roller 410 are arranged in parallel and on the same side of the lifting mechanism 200. In this way, the stability of the film winding roller 420 and the screen winding roller 410 during operation can be improved, and the structural compactness of the display device can be improved. Alternatively, the orthographic projection of the film winding roller 420 and the screen winding roller 410 at least partially overlaps. This structure is conducive to further compacting the structure of the display device and reducing the size of the display device in the thickness direction.

[0132] Specifically, the film winding roller 420 and the screen winding roller 410 are arranged along the length direction (i.e., the X-axis direction) of the housing 100, that is, the axis directions of the film winding roller 420 and the screen winding roller 410 are parallel to the length direction of the housing 100. One end of the film winding roller 420 is rotatably connected to the first support plate 181, and the other end of the film winding roller 420 is rotatably connected to the second support plate 182. The film winding roller 420 is arranged close to the screen fixing member 620 and on the side of the screen fixing member 620 away from the top panel 16.

[0133] Alternatively, the screen winding roller 410 is located directly below the film winding roller 420. One end of the film winding roller 420 is rotatably connected to the first support plate 181, specifically, the one end of the film winding roller 420 is rotatably connected to the second mounting hole 1812. The other end of the film winding roller 420 is rotatably connected to the second support plate 182, specifically, the other end of the film winding roller 420 is rotatably connected to the fourth mounting hole 1822. Similarly, the two ends of the screen winding roller 410 are rotatably connected to the first mounting hole 1811 and the third mounting hole 1821, respectively.

[0134] In some embodiments of the present application, referring to FIG. 2, the display device 1000 further comprises a guide member 500 extending along the width direction of the flexible screen 611, and the guide member 500 abuts against the non-display side to change the moving direction of the flexible screen 611. In this embodiment, by arranging the guide member 500 in the display device, the moving direction of the flexible screen 611 is changed by the guide member 500, so that interference between the flexible screen 611 and other components in the display device 1000 during movement is avoided, and the structural compactness of the display device 1000 is further improved.

[0135] Alternatively, the guide member 500 is arranged on the side of the lifting mechanism 200 away from the first opening 161, and the orthographic projection of the guide member 500 in the plane of the first opening 161 at least partially overlaps the orthographic projection of the lifting mechanism 200 in the plane of the first opening 161. In this way, the structural compactness of the display device is further improved, and the size of the display device 1000 in the thickness direction is reduced.

[0136] Exemplarily, the guide member 500 is arranged below the lifting mechanism 200 and close to the bottom surface of the housing 100, one end of the guide member 500 is rotatably connected with the first support plate 181, and the other end of the guide member 500 is rotatably connected with the second support plate 182.

[0137] Exemplarily, the guide member 500 comprises a guide roller or a guide wheel. In this way, the friction between the guide member 500 and the flexible screen 611 can be reduced.

[0138] In some embodiments of the present application, the lifting mechanism 200 comprises a lifting driving assembly 210 and a lifting roller 220, the lifting roller 220 abuts against the non-display side; the lifting driving assembly 210 is connected with the lifting roller 220, for driving the lifting roller 220 and the flexible screen 611 to enter or exit the mounting cavity 110 through the first opening 161; and the guide member 500 is arranged in parallel with the lifting roller 220.

[0139] Specifically, the edge of the guide member 500 towards the side of the back panel 13 coincides with the edge of the lifting roller 220 towards the side of the back panel 13 in the orthogonal projection of the plane where the first opening 161 is located. Taking the guide member 500 as an example, the edge of the guide member 500 close to the side of the back panel 13 is flush with the edge of the lifting roller 220 towards the side of the back panel 13, that is, the guide member 500 and the lifting roller 220 towards the side of the back panel 13 specifically share a tangent plane, and the tangent plane is a vertical plane.

[0140] In this way, the edge of the guide member 500 towards the side of the back panel 13 and the edge of the lifting roller 220 towards the side of the back panel 13 are on the same vertical plane, which is beneficial to avoid the deformation of the flexible screen 611 during the unfolding or folding process, improve the stability of the flexible screen 611 during the stretching or rolling process, and make the flexible screen 611 between the lifting roller 220 and the guide member 500 generally present a vertical plane, which is convenient for users to watch the information displayed on the flexible screen 611.

[0141] In some embodiments of the present application, the lifting mechanism 200 comprises a lifting driving assembly 210 and a lifting roller 220, the lifting roller 220 abuts against the non-display side; the lifting driving assembly 210 is connected with the lifting roller 220, for driving the lifting roller 220 and the flexible screen 611 to enter or exit the mounting cavity 110 through the first opening 161; the guide member 500 is arranged in parallel with the lifting roller 220, and the part of the flexible screen 611 between the guide member 500 and the lifting roller 220 presents a vertical plane. Here, the guide member 500 is arranged in parallel with the lifting roller 220, which means that the rotation axis of the guide member 500 is parallel to the rotation axis of the lifting roller 220.

[0142] Thus, it is beneficial to avoid deformation of the flexible screen 611 during unfolding or folding, improve the stability of the flexible screen 611 during stretching or folding, and facilitate the user to watch the information displayed on the flexible screen 611.

[0143] In some embodiments of the present application, referring to FIG. 2, the display device further comprises a screen fixing member 620 disposed in the mounting cavity 110 and configured to be connected with the flexible screen 611. Exemplarily, the screen fixing member 620 is fixedly connected with the second fixing part. The screen fixing member 620 and the screen winding roller 410 are disposed on the same side of the lifting mechanism 200. Thus, it is beneficial to increase the stability of the flexible screen 611 during stretching or folding, and reduce the size of the display device 1000 in the Y-axis direction.

[0144] Exemplarily, the screen fixing member 620 is close to the first opening 161 and located on the side of the first opening 161 close to the front panel 10. This structure is beneficial to reduce the size of the flexible screen 611 module 610 and improve the compactness of the display device 1000.

[0145] In some embodiments of the present application, the film winding roller 420 is disposed close to the screen fixing member 620 and located on the side of the screen fixing member 620 away from the top panel 16, the screen winding roller 410 is located on the side of the film winding roller 420 away from the screen fixing member 620, and the screen fixing member 620, the film winding roller 420 and the screen winding roller 410 are sequentially disposed along the Z-axis direction. In this embodiment, since the screen fixing member 620, the film winding roller 420 and the screen winding roller 410 are all disposed below the top panel 16, the top panel 16 can block dust or foreign matter from entering the screen fixing member 620 through the first opening 161, and prevent dust or foreign matter from falling on the film winding roller 420 or the screen winding roller 410 through the first opening 161, thereby improving the dustproof property and stability of the display device 1000 in the present application.

[0146] Specifically, the film winding roller 420 is disposed directly below the screen fixing member 620, the screen winding roller 410 is disposed directly below the film winding roller 420, and the orthographic projection of the screen fixing member 620 on the top panel 16, the orthographic projection of the film winding roller 420 on the top panel 16 and the orthographic projection of the screen winding roller 410 on the top panel 16 at least partially overlap. Thus, it is beneficial to reduce the size of the display device in the Y-axis direction, and make the structure of the display device 1000 in the present application more compact.

[0147] In some embodiments of the present application, the screen fixing member 620 is provided with a winding avoidance groove 626 on the side away from the top panel 16; the screen fixing member 620, the film winding roller 420 and the screen winding roller 410 are arranged along the height direction of the housing 100; the film winding roller 420 is close to the screen fixing member 620 and at least partially located in the winding avoidance groove 626. In this embodiment, by providing the screen fixing member 620 with a winding avoidance groove 626 on the side away from the top panel 16, the screen fixing member 620, the film winding roller 420 and the screen winding roller 410 are arranged along the height direction of the housing 100; the film winding roller 420 is close to the screen fixing member 620 and at least partially located in the winding avoidance groove 626, thereby facilitating the reduction of the size of the display device 1000 in the Z-axis direction and making the structure of the display device 1000 in the present application more compact.

[0148] Specifically, referring to FIGS. 20 and 21, the screen fixing member 620 comprises a screen fixing bottom plate and a screen fixing side plate 624 connected to each other, the screen fixing side plate 624 is arranged at one end of the screen fixing bottom plate close to the first opening 161, and the end of the screen fixing side plate 624 away from the screen fixing bottom plate extends close to the first opening 161. The screen fixing side plate 624 is an inclined surface, and the flexible screen 611 is connected to the screen fixing side plate 624. Exemplarily, the second fixing part is adhesively fixed on the screen fixing side plate 624.

[0149] Specifically, the screen fixing bottom plate comprises a first screen fixing bottom plate 621 and a second screen fixing bottom plate 622 arranged at intervals, and a bottom connecting plate 623 connecting the first screen fixing bottom plate 621 and the second screen fixing bottom plate 622, the first screen fixing bottom plate 621 is arranged at intervals with the screen fixing side plate 624, and the second screen fixing bottom plate 622 connects the screen fixing side plate 624 and the bottom connecting plate 623. The cross section of the screen fixing bottom plate is generally in the shape of the letter "Z", the side of the first screen fixing bottom plate 621 away from the top panel 16 forms a winding avoidance groove 626, and the winding avoidance groove 626 is used to avoid the screen winding roller 410 (such as the film winding roller 420 in the screen winding roller 410 or the screen winding roller 410) located below it. In this embodiment, since the screen fixing side plate 624 extends close to the first opening 161 and the screen fixing side plate 624 is an inclined surface, the winding avoidance groove 626 is arranged on the side of the screen fixing bottom plate away from the screen fixing side plate 624, which is conducive to reducing the length of the flexible screen 611 module 610, reducing the size of the display device 1000 in the Z-axis direction, making the structure of the display device 1000 in the present application more compact, and increasing the connection area between the screen fixing side plate 624 and the flexible screen 611 module 610, thereby increasing the structural stability of the display device 1000 in the present application.

[0150] Optionally, the screen fixing member 620 further comprises a pair of screen fixing end plates 625, which are arranged at two ends of the screen fixing bottom plate in the length direction, and each of the screen fixing end plates 625 is fixedly connected with the screen fixing bottom plate and the screen fixing side plate 624 on the same side. The screen fixing end plate 625 is used for being fixedly connected with the first support plate 181 or the second support plate 182.

[0151] In some embodiments of the present application, the screen body comprises a display part and a screen circuit board connected with each other, and the first connecting film 6113 and the second connecting film 6112 are respectively connected to two ends of the display part. The flexible screen module 600 further comprises a screen fixing member 620, and the screen circuit board is arranged on the screen fixing member 620. In this way, it is beneficial to avoid the connection between the screen circuit board and the display part from being broken under the action of external force (such as gravity or collision). For example, the display part and the screen circuit board are connected through signal lines, the screen circuit board is supported on the screen fixing bottom plate, and the display part is fixed on the screen fixing side plate 624.

[0152] In some embodiments of the present application, referring to FIGS. 2, 20 and 21, the screen fixing bottom plate comprises a first screen fixing bottom plate 621 and a second screen fixing bottom plate 622 arranged oppositely along the height direction of the housing, and a bottom connecting plate 623 connecting the first screen fixing bottom plate 621 and the second screen fixing bottom plate 622. The first screen fixing bottom plate 621 is located on the side of the second screen fixing bottom plate 622 close to the first opening 161. The first screen fixing bottom plate 621 and the bottom connecting plate 623 form a winding avoiding groove 626. The bottom connecting plate 623, the second screen fixing bottom plate 622 and the screen fixing side plate 624 form a screen mounting groove 627. The screen body comprises a display part and a screen circuit board, and the screen circuit board is located in the screen mounting groove. For example, the winding avoiding groove 626 is used for avoiding the film winding roller 631. In this way, by arranging the winding avoiding groove and the screen mounting groove on the screen fixing member 620, the screen fixing bottom plate can be prevented from pressing the screen circuit board, which is beneficial to improve the stability of the screen body, and at the same time, the size of the display device 1000 in the Z-axis direction is reduced, so that the structure of the display device 1000 is more compact.

[0153] In some embodiments of the present application, the screen winding roller 410 comprises a roller body and a motor. The roller body is hollow, and the motor is arranged in the roller body and connected with the roller body. In this way, it is beneficial to further improve the compactness of the structure of the display device 1000.

[0154] For example, the motor comprises a stator and a rotor. The stator is fixedly connected with the first support plate 181 or the second support plate 182, and the rotor is fixedly connected with the roller body.
