[0051] Embodiments of the present application

[0052] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work are within the scope of protection of the present application.

[0053] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation to the present application.

[0054] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

[0055] In the present application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described as "exemplary" in the present application is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the present application. 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.

[0056] In order to make the display device suitable for more occasions, such as convenient to carry, not to be blocked by the display screen when face-to-face communication, etc., the display device needs to have a storage function. At the same time, in order to achieve the effect of protection and dust prevention, a cover plate needs to be provided in the display device to control the opening or closing of the opening. In the related art, the cover plate generally reciprocates in a straight line direction (for example, reciprocates in a horizontal direction or a vertical direction) or flips relative to the shell of the display device to control the opening or closing of the display device inlet and outlet, but it will interfere with the lifting mechanism in the display device, or cannot be stored, or leads to a larger volume of the display device, or is not aesthetic.

[0057] With the advancement of technology, display devices have also undergone leapfrog development. At the same time, with the demand of consumers for space, there are liftable televisions on the market. Such liftable televisions can be lifted when in use, and can be withdrawn to the box when not in use, so as to save indoor space.

[0058] Generally, the liftable television is provided with a lifting opening at the top to facilitate the display screen to enter and exit, and a cover plate is provided at the lifting opening to play a dustproof and protective role. At present, such a cover plate can be automatically opened and closed with the opening and closing of the liftable television, which is convenient to use. In the related art, the cover plate generally reciprocates in a straight line direction, for example, reciprocates in a horizontal direction or a vertical direction; or flips relative to the shell of the display device to control the opening or closing of the display device inlet and outlet, and the setting of the cover plate occupies a large space, making the display device bulky and not aesthetic. In addition, in the related art, the movement mechanism for driving the cover plate to move is complex, has poor stability, and is prone to cause the cover plate to jam.

[0059] In view of this, the present application provides a cover plate mechanism with a novel structure. The cover plate in the present application can move in a first direction and a second direction, thereby avoiding other movement mechanisms (such as the lifting mechanism of the display device) in the display device when the cover plate in the present application is used in the display device, improving the storage performance of the display device, improving the appearance quality, and making the structure of the display device more compact, reducing the volume of the display device with the cover plate mechanism. In addition, in the present application, only one driving assembly is used to drive the cover plate to move in two different directions, i.e., the first direction and the second direction, which reduces the number of driving assemblies, is conducive to further reducing the volume of the cover plate mechanism, and reducing the volume of the display device with the cover plate mechanism. The present application will be further described below with reference to the accompanying drawings.

[0060] Referring to FIGS. 1-3, the display device 1000 according to an embodiment of the present disclosure includes a housing 100, a display screen 600, a lifting mechanism 200, and a cover mechanism 300. The housing 100 has a first opening 161 that is in communication with a mounting cavity 110 in the housing 100. The display screen 600, the lifting mechanism 200, and the cover mechanism 300 are all accommodated in the mounting cavity 110.

[0061] The lifting mechanism 200 is configured to drive the display screen 600 to move in and out of the mounting cavity 110 through the first opening 161.

[0062] It should be noted that, as shown in FIG. 3, the first opening 161 can be used for the display screen 600 and the lifting mechanism 200 in the display device 1000 to extend out of the mounting cavity 110 in the housing 100 to be exposed outside the housing 100. The display screen 600 and the lifting mechanism 200 are disposed directly below the first opening 161, and the display screen 600 and the lifting mechanism 200 move in a vertical direction to extend out of the mounting cavity 110 to be exposed outside the housing 100, so that a user can view the picture information displayed on the display screen 600 exposed outside the housing 100. When it is necessary to accommodate the display screen 600 and the lifting mechanism 200, the display screen 600 and the lifting mechanism 200 can be accommodated in the mounting cavity 110 through the first opening 161, and then the cover mechanism 300 is used to close the first opening 161. As shown in FIG. 1, after the display screen 600 and the lifting mechanism 200 are accommodated in the mounting cavity 110, the appearance of the display device 1000 is the appearance of the housing 100, which is conducive to improving the appearance quality of the display device 1000.

[0063] Referring to FIGS. 1 and 2, the housing 100 is generally cuboid-shaped, and includes a front panel 11 and a rear panel 13 that are oppositely disposed along a Y-axis direction, a left panel 14 and a right panel 15 that are oppositely disposed along an X-axis direction, and a top panel 16 and a bottom panel 17 that are oppositely disposed along the Y-axis direction. The front panel 11, the rear panel 13, the left panel 14, the right panel 15, the top panel 16, and the bottom panel 17 enclose the mounting cavity 110. Optionally, the cover mechanism 300 is fixed in the housing 100. Optionally, the cover mechanism 300 is fixed on a first support plate 181 in the housing 100, and the first support plate 181 is oppositely disposed with the left panel 14 or the right panel 3235b. It should be noted that the shape and structure of the housing 100, the specific structure of the lifting mechanism 200, and the specific structure of the display screen 600 do not belong to the main improvements of the present disclosure, and are not limited herein.

[0064] In order to avoid dust, sundries and the like from entering the installation cavity 110 of the shell 100 through the first opening 161, affecting the normal use of the display device 1000. The cover plate mechanism 300 in the present application is used to open or close the first opening 161 on the shell 100.

[0065] In the present application, referring to FIGS. 6, 7, 13 and 14, the cover plate mechanism 300 includes a cover plate assembly 310, a guide assembly 320 and a driving assembly 330. Among them, the cover plate assembly 310 includes a cover plate 311, as shown in FIGS. 4 and 5, the cover plate 311 includes a first position and a second position, that is, the cover plate 311 in the present application can be switched between the first position and the second position.

[0066] Exemplarily, referring to FIGS. 1 and 5, the first position is the position of the first opening 161. When the cover plate 311 is located at the first position, the cover plate 311 is located in the first opening 161 to shield or seal or close the first opening 161. In this way, the side of the cover plate 311 away from the installation cavity 110 can be flush with the upper surface (i.e. the side of the top panel away from the installation cavity 110) of the shell 100, thereby further improving the appearance quality of the display device.

[0067] Exemplarily, the second position is a certain position in the installation cavity 110. Specifically, referring to FIGS. 1 and 4, the first opening 161 is arranged on the top panel 16, and the second position is a position close to the top panel 16 and the first opening 161, and located below the top panel 16 and on one side of the first opening 161, that is, the cover plate 311 is located at the second position and is completely misaligned with the first opening 161. In this way, when the cover plate 311 is located at the second position, the first opening 161 can be completely opened, and interference between the cover plate 311 and the lifting mechanism 200 can be avoided, and the structure of the display device 1000 is more compact.

[0068] It should be noted that the above first position and second position are only one example of the cover plate 311 used in the display device 1000, and those skilled in the art can set the first position and the second position of the cover plate 311 according to the specific use scene, which is not limited herein.

[0069] In the embodiment of the present application, the guide assembly 320 is used to guide the movement of the cover plate assembly 310, that is, the guide assembly 320 restricts the movement trajectory of the cover plate assembly 310, or the guide assembly 320 restricts the movement trajectory of the cover plate 311 from the first position to the second position.

[0070] The guiding assembly 320 comprises a base 321 and a guiding piece (a first guiding piece 322 or a second guiding piece 323), the base 321 is provided with a first guiding groove 3211, and the guiding piece is in sliding connection with the first guiding groove 3211, that is, the guiding piece is configured to be capable of sliding along the first guiding groove 3211. The cover plate 311 is connected with the guiding piece.

[0071] The first guiding groove 3211 has a component in a first direction and a component in a second direction, and the first direction and the second direction are different directions. The guiding piece moves along the first guiding groove 3211 to make the cover plate 311 move back and forth between the first position and the second position, that is, the first guiding groove 3211 is used to constrain the movement track of the guiding piece, and then the cover plate 311 on the guiding piece is constrained to move from the first position to the second position, thereby improving the control accuracy of the cover plate 311.

[0072] Exemplarily, referring to FIGS. 6-8, the first direction and the second direction are perpendicular to each other. For example, the first direction is a horizontal direction, and the second direction is a vertical direction. At this time, the first guiding groove 3211 has displacement components in the horizontal direction and the vertical direction, and correspondingly, the guiding piece generates displacement in the horizontal direction and the vertical direction during the sliding process along the first guiding groove 3211, and therefore, the cover plate 311 on the guiding piece generates displacement in the horizontal direction and the vertical direction. For ease of understanding, the first direction is taken as the horizontal direction and the second direction is taken as the vertical direction as an example for description below unless otherwise specified. Of course, in other embodiments of the present application, the first direction and the second direction can also be not perpendicular to each other, which is not limited herein.

[0073] It can be understood that, since the first guiding groove 3211 has a component in the first direction and a component in the second direction, the guiding piece can move in the first direction and also can move in the second direction when moving along the first guiding groove 3211. Correspondingly, the cover plate 311 on the guiding piece has certain displacement in the first direction and the second direction during the movement of the guiding piece from the first position to the second position, so that the cover plate 311 in the present application can move in two different directions of the first direction and the second direction when switching between the first position and the second position, which is beneficial to avoid other moving mechanisms (such as the lifting mechanism 200 of the display device) in the display device, improve the storage performance of the display device, improve the appearance quality, make the structure of the display device more compact, and reduce the volume of the display device with the cover plate mechanism 300.

[0074] Please refer to FIG. 6, FIG. 11, FIG. 13 and FIG. 14, the driving assembly 330 comprises a driving slider 331 configured to reciprocate along a first direction, the guide piece is in sliding connection with the driving slider 331 along a second direction; the driving slider 331 drives the guide piece to move along the first guide groove 3211, so as to make the cover plate 311 reciprocate between the first position and the second position.

[0075] Specifically, the driving slider 331 can reciprocate along the first direction under the driving action of the driving motor or external force, the driving slider 331 drives the guide piece to slide along the first guide groove 3211, and the guide piece drives the cover plate 311 on it to reciprocate between the first position and the second position in the process of sliding along the first guide groove 3211.

[0076] In summary, in the present application, the first guide groove 3211 is arranged in the cover plate mechanism 300, the first guide groove 3211 has a component along the first direction and a component along the second direction, the first direction and the second direction are different directions, the cover plate 311 is connected with the guide piece, the guide piece is in sliding connection with the first guide groove 3211, the driving slider 331 is configured to reciprocate along the first direction, the guide piece is in sliding connection with the driving slider 331 along the second direction; the driving slider 331 drives the guide piece to move along the first guide groove 3211, so as to make the cover plate 311 reciprocate between the first position and the second position, so that the cover plate 311 in the present application can move along the first direction and the second direction, so that when the cover plate 311 in the present application is used in the display device, it is beneficial to avoid other moving mechanisms (such as the lifting mechanism 200 of the display device) in the display device, improve the storage performance of the display device, improve the appearance quality, and make the structure of the display device more compact, reduce the volume of the display device with the cover plate mechanism 300. In addition, in the present application, only one driving assembly 330 is used to drive the cover plate 311 to move along the first direction and the second direction, which reduces the number of driving assemblies 330, is beneficial to further reduce the volume of the cover plate mechanism 300, and reduce the volume of the display device with the cover plate mechanism 300.

[0077] In some embodiments of the present application, referring to FIG. 8 and FIG. 14, the first guide slot 3211 has a first slot segment 3211c and a second slot segment 3211d which are in communication with each other, the first slot segment 3211c extends along the first direction, and the second slot segment 3211d has a component along the first direction and a component along the second direction, that is, the second slot segment extends along the first direction and the second direction. This embodiment is advantageous in increasing the displacement of the cover plate 311 in the first direction (for example, the horizontal direction) when the cover plate 311 moves from the first position to the second position, so that when the first opening 161 and the lifting mechanism 200 are large in size in the first direction, the cover plate 311 can also be completely staggered with the first opening 161 and avoid interference with the lifting mechanism 200.

[0078] For example, the first slot segment 3211c extends along the horizontal direction, that is, the first slot segment 3211c is a horizontal segment.

[0079] Alternatively, in some embodiments of the present application, referring to FIG. 8, the second slot segment 3211d can be an arc-shaped segment, and the second slot segment 3211d is tangent to the first slot segment 3211c. In other embodiments of the present application, referring to FIG. 9, the second slot segment 3211d can also be an inclined segment which is arranged at an angle (for example, an obtuse angle) with the horizontal direction. It should be noted that the curvature of the arc-shaped segment and the inclination angle of the inclined segment are not limited and can be set according to specific needs by the skilled person.

[0081] In some embodiments of the present application, the guide includes a guide column (the first guide column 3222 or the second guide column 3233), and the guide column is in sliding fit with the first guide slot 3211. This embodiment is advantageous in making the structure of the cover plate mechanism 300 simpler and more compact by arranging the guide column in sliding fit with the first guide slot 3211.

Exemplarily, the two ends of the cover plate 311 in the length direction are respectively provided with a guide assembly and a driving assembly, and the two ends of the cover plate 311 in the length direction are respectively fixedly connected to the corresponding cover plate connecting plate 312, thereby facilitating the stability of the cover plate during the movement.

[0085] Specifically, the end of the guide block 3221 close to the driving sliding block 331 is provided with a through hole 3221a for mounting the first guide post 3222, the first guide post 3222 is fixedly arranged in the through hole 3221a, and the two ends of the first guide post 3222 protrude out of the through hole 3221a and extend into the first guide groove 3211 so that the first guide post 3222 can slide along the first guide groove 3211.

[0086] Specifically, the limiting assembly 340 comprises a first guide rail 341 and a second guide rail 342 arranged oppositely. A gap between the first guide rail 341 and the second guide rail 342 forms an avoiding groove 3449. Exemplarily, when both ends of the first guide column 3222 are in sliding fit with the corresponding first guide groove, both sides of the guide block 3221 are respectively provided with an avoiding groove 3449 for avoiding the first guide column 3222.

In this way, the guide block 3221 can be slidably arranged in the first sliding groove 3411 and the second sliding groove 3421 in the second direction, and the stability of the guide block 3221 sliding in the second direction can be improved.

[0087] Exemplarily, the first guide rail 341 and the second guide rail 342 can be made of self-lubricating material, for example, the material of the first guide rail 341 and the second guide rail 342 is nylon.

The limiting sleeve 344 limits the first guide rail 341 and the second guide rail 342 in the second direction. The limiting sleeve 344 is provided with a first avoiding opening 3448. The first avoiding opening 3448 is in communication with the avoiding groove 3449 for avoiding the first guide column 3222.

[0089] Specifically, the limiting sleeve 344 extends along the second direction. The limiting sleeve 344 comprises a first limiting side plate 3441, a second limiting side plate 3442, and a connecting side plate 3443, the first limiting side plate 3441 and the second limiting side plate 3442 are arranged on the same side of the connecting side plate 3443 and are oppositely arranged; the first limiting side plate 3441 is provided with a first side plate folding edge 3444, the first side plate folding edge 3444 is oppositely arranged with the connecting side plate 3443 and extends towards the second limiting side plate 3442, the first side plate folding edge 3444, the first limiting side plate 3441 and the connecting side plate 3443 form the first guide rail mounting groove 3446 for mounting the first guide rail 341. The first side plate folding edge 3444 and the second limiting side plate 3442 have a gap therebetween, which is used to avoid the first guide column 3222. The connecting side plate 3443 is provided with a first avoiding opening 3448 at a position opposite to the avoiding groove 3449, which is used to avoid the first guide column 3222. In this way, the first side plate folding edge 3444, the first limiting side plate 3441 and the connecting side plate 3443 can limit the first guide rail 341 from different directions, which is beneficial to the stability of the limiting assembly 340 and improves the stability of the guide block 3221 during sliding.

[0090] Exemplarily, the first limiting side plate 3441 is fixedly connected with the driving sliding block 331, and / or the second limiting side plate 3442 is fixedly connected with the driving sliding block 331, and / or the connecting side plate 3443 is fixedly connected with the driving sliding block 331.

The second side plate folding edge 3445 and the first limiting side plate 3441 have a gap therebetween, which is used to avoid the first guide column 3222. The connecting side plate 3443 is provided with a first avoiding opening 3448 at a position opposite to the avoiding groove 3449, which is used to avoid the first guide column 3222. In this way, the second side plate folding edge 3445, the second limiting side plate 3442 and the connecting side plate 3443 can limit the second guide rail 342 from different directions, which is beneficial to the stability of the limiting assembly 340 and improves the stability of the guide block 3221 during sliding. Optionally, the bottom end of the first limiting side plate 3441 is provided with a first side plate avoiding opening 3441a, and the bottom end of the first guide rail 341 away from the second guide rail 342 is provided with a first extending portion 3412, which is arranged in the first side plate avoiding opening 3441a. In this way, the first extending portion 3412 can increase the connection area between the first guide rail 341 and the driving sliding block 331, thereby increasing the connection strength between the first guide rail 341 and the driving sliding block 331, and arranging the first extending portion 3412 in the first side plate avoiding opening 3441a is beneficial to improve the compactness of the cover plate mechanism 300 and reduce the volume of the cover plate mechanism 300.

[0092] Similarly, the bottom end of the second limiting side plate 3442 is provided with a second side plate avoiding opening (exemplarily, the second side plate avoiding opening is symmetrically arranged with the first side plate avoiding opening 3441a), and the bottom end of the second guide rail 342 away from the first guide rail 341 is provided with a second extending portion 3422, which is arranged in the second side plate avoiding opening. In this way, the second extending portion can increase the connection area between the second guide rail 342 and the driving sliding block 331, thereby increasing the connection strength between the second guide rail 342 and the driving sliding block 331, and arranging the second extending portion in the second side plate avoiding opening is beneficial to improve the compactness of the cover plate mechanism 300 and reduce the volume of the cover plate mechanism 300.

[0093] In some embodiments of the present application, referring to FIGS. 6 and 10, the guide piece further comprises a guide block 3221, the cover plate mechanism 300 further comprises a limiting assembly 340 connected with the driving slider 331, the limiting assembly 340 comprises a limiting side plate 345, and the guide column is arranged in the guide block 3221; the limiting side plate 345 comprises a second guide groove 345a extending along the second direction, the second guide groove 345a is communicated with the first guide groove 3211, and the guide column is further arranged to be slidably arranged in the second guide groove 345a along the second direction. In this way, by arranging the second guide groove 345a extending along the second direction on the limiting side plate 345, the second guide groove 345a limits the sliding track of the first guide column 3222 and the guide block 3221 along the second direction, thereby further improving the control accuracy of the sliding of the first guide column 3222 and the guide block 3221 along the second direction.

[0094] Specifically, the guide block 3221 extends along the second direction. The driving slider 331 is generally in the shape of a square block, the limiting side plate 345 is arranged near the edge of the driving slider 331, the limiting side plate 345 is arranged on the side of the driving slider 331 facing the guide piece, and the limiting side plate 345 and the driving slider 331 are generally arranged vertically. Exemplarily, the limiting side plate 345 and the driving slider 331 are an integral structure. The guide block 3221 (or the guide block 3221 and the limiting assembly 340) is arranged on the inner side of the limiting side plate 345 (i.e. the side of the limiting side plate 345 facing the driving slider 331), one end of the guide column extends into the first guide groove 3211 through the second guide groove 345a, so that the guide column can also slide along the second guide groove 345a in the process of sliding along the first guide groove 3211. It should be noted that the specific structure of the guide block 3221 and the connection mode of the guide column and the guide block 3221 have been described in detail in the foregoing, and will not be repeated here.

[0095] For the convenience of understanding, the movement process of the guide column and the guide block 3221 in the present application will be described by taking the first guide slot 3211 including the first slot segment 3211c (i.e. the horizontal segment) and the second slot segment 3211d (i.e. the arc-shaped segment) arranged in sequence in FIG. 8 as an example. When the guide column is located at the horizontal segment, the driving slider 331 drives the guide column to move in the first direction (i.e. the horizontal direction), and the guide column drives the guide block 3221 and the cover plate 311 to move in the first direction. At this time, no relative displacement is generated between the guide column and the guide block 3221 and the driving slider 331, i.e. the guide column does not move in the second sliding slot 3421 during this process. When the guide column is located at the arc-shaped segment, the driving slider 331 drives the guide column to move in the first direction (i.e. the horizontal direction). At this time, the guide column includes a movement component in the first direction and a movement component in the second direction (i.e. the vertical direction) in the process of sliding along the arc-shaped segment, and the guide column moves along the first guide slot 3211 and the second guide slot 345a at the same time. The guide column drives the guide block 3221 and the cover plate 311 to move in the first direction and the second direction at the same time, and the guide column, the guide block 3221 and the cover plate 311 move in the second direction relative to the driving slider 331.

[0096] In some embodiments of the present application, the guide further includes a guide block 3221, and the guide column is arranged in the guide block 3221. The cover plate mechanism 300 further includes a limiting assembly 340 connected with the driving slider 331. The limiting assembly 340 includes a sliding slot extending in the second direction and a second guide slot 345a. The guide block 3221 is arranged to be slidably arranged in the sliding slot in the second direction, and the guide column is arranged to be slidably arranged in the second guide slot 345a in the second direction. In this way, the movement track of the guide block 3221 in the second direction is limited by the sliding slot, and the movement track of the guide column in the second direction is limited by the second guide slot 345a, so as to further improve the control accuracy of the cover plate mechanism 300 in the present application.

[0097] It should be noted that the specific structure of the guide block 3221, the connection mode of the guide column and the guide block 3221, the specific structure of the limiting assembly 340 and the specific arrangement of the limiting assembly 340 and the driving slider 331 in this embodiment have been described in detail in the foregoing, and will not be described here.

For example, along the extension direction of the first guide groove 3211, the first guide groove 3211 includes a starting point 3211a and an ending point 3211b arranged oppositely, and the position of the ending point 3211b is higher than that of the starting point 3211a. When the guide column in the first guide groove 3211 is located at the starting point 3211a, the cover plate 311 is accommodated below the top panel 16, and at this time, the first opening 161 is opened. When the driving slider 331 drives the guide column to slide along the first guide groove 3211 from the starting point 3211a to the ending point 3211b, the guide column drives the cover plate 311 above it to slide along the same or similar track line as the first guide groove 3211, and when the guide column slides along the first guide groove 3211 to the ending point 3211b, the cover plate 311 moves to the position sealing the first opening 161, and at this time, the first opening 161 is closed.
