[0072] The present application embodiment provides a display device, such as Figure 1 As shown, the display device includes a base 10, a first display layer 20, a second display layer 30, a driving assembly 50 and a lifting assembly 60;

[0073] The first display layer 20 is slidably connected to the base 10, the second display layer 30 is mounted on the base 10, and the first display layer 20 is connected to the driving assembly 50;

[0074] The driving assembly 50 is installed in the middle of the base 10 , and is used to drive the first display layer 20 to move in a direction away from or close to the second display layer 30 ;

[0075] The lifting assembly 60 is installed on the base 10 , and is used to drive the first display layer 20 to move in a direction perpendicular to the display surface of the first display layer 20 .

[0076] The display device provided in the embodiment of the present application drives the first display layer 20 through the driving component 50 so that the first display layer 20 moves in a direction away from the second display layer 30 (the display device is expanded), or moves in a direction close to the second display layer 30 (the display device is contracted), and in the process of driving the first display layer 20, the first display layer 20 and the second display layer 30 are not in the same plane, so there will be a relatively large gap between the first display layer 20 and the second display layer 30 in the vertical direction, so the first display layer 20 is driven to move in a direction perpendicular to the display surface of the first display layer 20 through the lifting component 60, so that when the display device is expanded, the first display layer 20 and the second display layer 30 are moved to the same plane, which is beneficial to reducing the gap between the display layers and improving the display effect; when the display device is contracted, it is also convenient to increase the height of the first display layer 20 so as to restore it to its original position. In this way, the display device provided in the embodiment of the present application can effectively reduce the gap between the first display layer 20 and the second display layer 30, thereby improving the display effect; and the display device can be expanded or shrunk according to actual needs, greatly improving the applicability of the display device.

[0077] It should be noted that the first display layer 20 and the second display layer 30 are different display split screens of the display device, and the display surface of the first display layer 20 is the side of the first display layer 20 away from the second display layer 30 .

[0078] In applications, such as Figures 1 to 4 As shown, the display device includes two states:

[0079] like Figure 1 and Figure 2 As shown, when the display device is in the first state (the original state may also be referred to as the contracted state), the second display layer 30 is located under the orthographic projection of the first display layer 20, and the display screen of the display device is composed of the first display layer 20, that is, the first state may be that the first display layer 20 alone provides a display image;

[0080] like Figure 3 As shown, when the display device is in the second state (extended state), the first display layer 20 is located on the side of the second display layer 30 away from the driving component 50, and the first display layer 20 and the second display layer 30 are located in the same plane, and the display screen of the display device is composed of the first display layer 20 and the second display layer 30, that is, the second state can be that the first display layer 20 and the second display layer 30 jointly provide a display picture.

[0081] The display device provided in the embodiment of the present application can meet the requirement that when in an expanded state, each display split screen (the first display layer 20 and the second display layer 30) is in the same plane, and the gap between the split screens can be reduced to a minimum, thereby improving the display effect; the display device provided in the embodiment of the present application can restore the expanded display screen to a contracted state, and can be used cyclically in this way, and the operation is simple and convenient.

[0082] In some embodiments, Figure 4 As shown, the display device further includes a third display layer 40 located below the second display layer 30, and the third display layer 40 is slidably connected to the base 10;

[0083] The driving component 50 is also used to drive the third display layer 40 to move in a direction away from or close to the driving component 50. Having multiple display layers can further expand the maximum display area of ​​the display device, thereby meeting the demand for a larger display area.

[0084] In applications, such as Figure 5 and Figure 6 As shown, the display device includes two states:

[0085] like Figure 5 As shown, when the display device is in the first state (the original state may also be referred to as the contracted state), the third display layer 40 and the second display layer 30 are located under the orthographic projection of the first display layer 20, and the display screen of the display device is composed of the first display layer 20, that is, the first state may be that the first display layer 20 alone provides a display image;

[0086] like Figure 6 As shown, when the display device is in the second state (expanded state), the first display layer 20 is located on the side of the second display layer 30 away from the driving component 50, the third display layer 40 is located between the first display layer 20 and the second display layer 30, and the first display layer 20, the second display layer 30 and the third display layer 40 are located in the same plane, and the display screen of the display device is composed of the first display layer 20, the second display layer 30 and the third display layer 40, that is, the second state can be the first display layer 20, the second display layer 30 and the third display layer 40 jointly provide a display picture. In this way, the display area of ​​the display device can be further increased, thereby meeting the display demand of a larger area.

[0087] It should be noted that when the display device is in a retracted state, the first display layer 20 is located at the top of the display device, and the second display layer 30 and the third display layer 40 are located under the orthographic projection of the first display layer 20; when the display device is in an extended state, the first display layer 20, the second display layer 30 and the third display layer 40 are just spliced ​​to form a display screen of the display device, which are on the same plane and have no overlapping parts. In applications, the first display layer 20, the second display layer 30 and the third display layer 40 are display screens or display panels.

[0088] It should be noted that the display device also includes a third state, ie, a state in the process of switching from the first state to the second state, or a state in the process of switching from the second state to the first state.

[0089] In applications, such as Figure 4 As shown, a first protective layer 21 is provided on the side of the first display layer 20 close to the second display layer 30, and the first protective layer 21 is a rigid protective layer. A second protective layer 31 is provided on the side of the second display layer 30 away from the first display layer 20 and corresponding to the position of the third display layer 40, and the second protective layer 31 is a rigid protective layer. A third protective layer 32 is provided on the side of the second display layer 30 away from the first display layer 20 and corresponding to the position of the driving component 50, and the third protective layer 32 is a smooth layer. In a specific embodiment, the material of the rigid protective layer can be aluminosilicate glass, soda-lime glass, sapphire glass, polycarbonate, polymethyl methacrylate, etc. In this way, since the first display layer 20 will move back and forth relative to the second display layer 30 when the display device switches states, a rigid protective layer can effectively protect the first display layer 20 and the second display layer 30 to avoid friction damage. The material of the smooth layer can be perfluoropolyether, fluorosilane, diamond-like carbon, silicon dioxide, polyurethane, silicone material, etc. The smooth layer is used to reduce the friction between the driving component 50 and the second display layer 30 , thereby preventing the portion of the second display layer 30 connected to the driving component 50 from being damaged by friction.

[0090] In some embodiments, Figure 4 and Figure 7As shown, the display device also includes a third display layer 40 located below the second display layer 30, and a positioning member 43 for positioning and cooperating with the second display layer 30 is provided on the side of the third display layer 40 close to the driving assembly 50. When the driving assembly 50 drives the third display layer 40, it can be clearly known whether the third display layer 40 has moved into place through the cooperation of the positioning member 43, thereby improving the convenience of use. In application, the positioning member 43 includes a positioning groove 430 arranged on the side of the third display layer 40 close to the driving assembly 50 and a coordination key 431 arranged on the side wall of the positioning groove 430. The third display layer 40 is driven by the driving assembly 50 to move in a direction away from the driving assembly 50. When the positioning groove 430 on the third display layer 40 moves to the side of the second display layer 30, the side of the second display layer 30 falls on the positioning groove 430, and the coordination key 431 on the positioning groove 430 coordinates the side of the second display layer 30, thereby obtaining the second display layer 30 and the third display layer 40 in the same plane. In order to ensure that the second display layer 30 and the third display layer 40 can be in the same plane, during the design, the thickness of the third display layer 40 is slightly greater than that of the second display layer 30, and the depth of the positioning groove 430 is equal to the thickness of the second display layer 30, so that after the third display layer 40 moves to the preset position, the second display layer 30 can just fall into the positioning groove 430, and the second display layer 30 and the third display layer 40 can be in the same plane.

[0091] In some embodiments, Figure 4 and Figure 7 As shown, the base 10 includes a base plate 11 and a telescopic housing 12;

[0092] A mounting hole is provided in the middle of the base plate 11, and the driving assembly 50 is installed in the mounting hole;

[0093] The telescopic housing 12 includes a sliding portion 121 and a connecting portion 122 , wherein the sliding portion 121 is slidably connected to the substrate 11 , and the connecting portion 122 is connected to the first display layer 20 ;

[0094] Among them, a first guide groove 100 is formed between the substrate 11 and the telescopic shell 12, and a first air duct 120 connecting the first guide groove 100 and the lifting assembly 60 is opened in the telescopic shell 12. When the telescopic shell 12 and the first display layer 20 move in a direction away from or close to the driving assembly 50, the pressure in the first guide groove 100 and the first air duct 120 changes to provide a power source to the lifting assembly 60.

[0095] like Figure 8As shown, the telescopic housing 12 is driven to move by the driving assembly 50. When the telescopic housing 12 moves in a direction away from the driving assembly 50, that is, the telescopic housing 12 and the first display layer 20 move in a direction away from the substrate 11 (the substrate 11 is fixed to the driving assembly 50, and the substrate 11 is immovable), the first guide groove 100 is compressed, causing the air pressure in the first guide groove 100 to increase, and is transmitted to the lifting assembly 60 through the first air channel 120, thereby providing a power source for the lifting assembly 60. The advantage of such a design is that the driving assembly 50 can provide power to the lifting assembly 60 while driving the telescopic housing 12 to move (driving the first display layer 20 to move in a direction away from the driving assembly 50 at the same time), so that after the first display layer 20 moves horizontally to a preset position, the first display layer 20 is moved in the vertical direction so that it is in the same plane as the second display layer 30. Similarly, when the first display layer 20 needs to be retracted, the telescopic shell 12 moves toward the direction close to the substrate 11, the pressure in the first guide groove 100 decreases, the gas flow direction changes, the lifting assembly 60 raises the first display layer 20, and the telescopic shell 12 returns to its original position to achieve retraction.

[0096] In some embodiments, Figure 4 and Figure 7 As shown, a first stopper 111 is provided at one end of the substrate 11 away from the driving assembly 50, and a second stopper 123 is provided at one side of the telescopic housing 12 close to the opening of the first guide groove 100, and the first stopper 111 and the second stopper 123 are stopper protrusions. The existence of the first stopper 111 and the second stopper 123 can form a long strip of the first guide groove 100 between the telescopic housing 12 and the substrate 11, and the two can be positioned relative to each other when the two move relative to each other, so as to ensure that the first display layer 20 can move to a preset position.

[0097] Furthermore, in order to speed up the conversion of the display device from the extended state to the contracted state, a magnetic attraction component, specifically an electromagnet, can be provided on the telescopic shell 12 and the driving assembly 50. When expansion is required, the electromagnet is not energized, and the telescopic shell 12 and the driving assembly 50 can be separated normally; when contraction is required, the electromagnet is energized to increase the suction force between the two, thereby achieving rapid resetting and contraction.

[0098] In applications, such as Figure 4 and Figure 7 As shown, the base 10 further includes a connecting housing 14 connected to the driving assembly 50, a first magnetic member 141 is provided on the connecting housing 14, a second magnetic member 124 is provided on the telescopic housing 12, and the first magnetic member 141 and the second magnetic member 124 are magnetically matched. In a specific embodiment, the first magnetic member 141 is a magnetic metal, and the second magnetic member 124 is an electromagnet; of course, the positions of the first magnetic member 141 and the second magnetic member 124 can be exchanged.

[0099] In some embodiments, Figure 4 and Figure 8 As shown, the lifting assembly 60 includes a cylinder 61 and an elastic member 62;

[0100] The cylinder 61 is mounted on the connecting portion 122; in a specific embodiment, the cylinder 61 includes a piston rod 611 and a lower pressing plate 612. One end of the piston rod 611 is connected to the first air channel 120, and the other end of the piston rod 611 is connected to the lower pressing plate 612, and the lower pressing plate 612 is connected to the connecting portion 122.

[0101] One end of the elastic member 62 is connected to the connecting portion 122, and the other end of the elastic member 62 is connected to the sliding portion 121, wherein the thrust generated by the pressure change in the first air channel 120 is used to push the piston rod 611 of the cylinder 61, so as to drive the first display layer 20 to move in a direction perpendicular to the display surface of the first display layer 20. The first air channel 120 connects the top of the cylinder 61 with the first guide groove 100, so that the thrust generated in the first guide groove 100 can be used to push the piston rod 611. In application, the elastic member 62 is a spring.

[0102] In some embodiments, Figure 4 , Figures 7 to 11 As shown, the drive assembly 50 includes a motor 51 and a support nut 52;

[0103] The motor 51 is installed in the middle of the base 10, specifically, in the middle of the substrate 11. The motor 51 has a rotating shaft 511, and a surface of the rotating shaft 511 is provided with threads.

[0104] The support nut 52 is threadedly connected to the rotating shaft 511, and a compression space 500 is formed between the rotating shaft 511 and the nut. The side of the support nut 52 away from the rotating shaft 511 is connected to the second display layer 30;

[0105] The support nut 52 is provided with a second air passage 520 connecting the telescopic housing 12 and the compression space 500. The motor 51 is rotated to change the pressure in the compression space 500. The changed pressure in the compression space 500 is driven by the second air passage 520 to move toward or away from the motor 51. In this way, the first display layer 20 can move in the horizontal direction (i.e., the length or width direction of the first display layer 20) following the sliding portion 121 of the telescopic housing 12 and in the vertical direction (i.e., perpendicular to the thickness direction of the first display layer 20) following the connection portion 122 of the telescopic housing 12 through the rotation of the motor 51.

[0106] In some embodiments, Figure 7As shown, the base 10 also includes a support shell 13 connected to the motor 51, and a third display layer 40 is slidably arranged above the support shell 13. The support nut 52 is provided with an air hole 521, and the third display layer 40 is connected with the compression space 500 through the air hole 521. In this way, the pressure in the compression space 500 changes by rotating the motor 51, and the changed pressure in the compression space 500 drives the third display layer 40 to move toward or away from the motor 51 through the air hole 521. In this way, the third display layer 40 can be expanded. When the third display layer 40 moves to the preset position, the lifting assembly 60 moves the first display layer 20 to a height in the same plane as the third display layer 40. At this time, the second display layer 30 will fall into the positioning groove 430 and be positioned and matched with the third display layer 40, so that the three display layers are in the same plane.

[0107] In application, a second protective layer 31, i.e. a smooth layer, is provided between the support nut and the second display layer 30 to ensure that when the motor 51 rotates, only the nut rotates relatively, while the second display layer 30 does not rotate, thereby reducing friction between the two and protecting the second display layer 30 from damage.

[0108] In some embodiments, Fig.10 and Fig.11 As shown, a restraining groove 522 is further provided on one side of the support nut 52 away from the compression space 500 , so that the support nut 52 moves downward with the second display layer 30 , thereby being engaged with the third display layer 40 .

[0109] In some embodiments, Figure 7 As shown, the base 10 also includes a connecting shell 14, and a clearance groove 140 is provided on one side of the connecting shell 14 close to the rotating shaft 511, and the clearance groove 140 is used to make way for the support nut 52. Because the rotating shaft 511 of the motor 51 and the support nut 52 are threadedly matched, when the rotating shaft 511 rotates, the support nut 52 will move downward relative to the rotating shaft 511. At this time, the clearance groove 140 provides space for the support nut 52, so that the second display layer 30 and the third display layer 40 and the first display layer 20 are in the same plane. In application, the first magnetic member 141 is provided on the connecting shell 14, and the first magnetic member 141 is an electromagnet. The connecting shell 14 provides an installation position for the electromagnet, and a circuit for supplying power to the electromagnet can also be provided in the connecting shell 14.

[0110] In some embodiments, Figure 4 , Figures 7 to 11As shown, a second guide groove 200 is formed between the third display layer 40 and the support shell 13, a third limiter 41 is provided at one end of the third display layer 40 close to the support nut 52, and a fourth limiter 131 is provided at one end of the support shell 13 away from the support nut 52, and the third limiter 41 and the fourth limiter 131 are limited and matched. The third limiter 41 and the fourth limiter 131 are limit protrusions. In this way, when the third display layer 40 moves, the presence of the third limiter 41 and the fourth limiter 131 can ensure that the third display layer 40 moves to a preset position to be embedded with the second display layer 30.

[0111] In applications, such as Figure 7 As shown, a third magnetic part 42 is also provided on the side of the third display layer 40 close to the support nut 52. The third magnetic part 42 is a heterogeneous magnet. Such a configuration can accelerate the contraction of the third display layer 40. The specific principle is that the support nut 52 is usually made of metal, and a heterogeneous magnet is provided on the side of the third display layer 40 close to the support nut 52. When the display device needs to be contracted, the heterogeneous magnet can provide suction to facilitate the rapid contraction of the third display layer 40 and magnetic fixation to the support nut 52.

[0112] In applications, such as Figure 7 As shown, a guide fixing key is further provided on one side of the telescopic housing 12 away from the base plate 11. The existence of the guide fixing key forms a clearance space between the telescopic housing 12 and the supporting housing 13 to facilitate the opening of the second air passage 520, so that the pressure change in the second air passage 520 pushes the guide fixing key to move the entire telescopic housing 12.

[0113] In some embodiments, Figure 2 and Figure 3 As shown, the first display layer 20 is provided with at least two, and the second display layer 30 is provided with at least two. Figures 12 to 17 As shown, the first display layer 20 and the second display layer 30 are respectively provided with two, four, etc. Further, the third display layer 40 is also provided with two, four, etc.

[0114] In some embodiments, Figures 12 to 17As shown, the projections of the first display layer 20 and the second display layer 30 on the base 10 are in the shape of a rectangle, a triangle, a sector, a pentagon, or a hexagon. In application, the projection of the third display layer 40 on the base 10 is in the shape of a rectangle, a triangle, a sector, a pentagon, or a hexagon. The projections of the first display layer 20, the second display layer 30, and the third display layer 40 on the base 10 may all be rectangles, or they may be different, and may be rectangles, triangles, sectors, hexagons, etc., respectively. Such a setting can effectively improve the applicability of the display device, and the shape and number of the display layers can be designed according to different needs.

[0115] In some embodiments, Figure 4 , Figures 7 to 11 As shown, the display device includes a base 10, a first display layer 20, a second display layer 30, a third display layer 40, a driving assembly 50 and a lifting assembly 60;

[0116] The base 10 includes a substrate 11, a telescopic housing 12, a supporting housing 13 and a connecting housing 14. The telescopic housing 12 includes a sliding portion 121 and a connecting portion 122. The sliding portion 121 is slidably connected to the substrate 11, the connecting portion 122 is connected to the first display layer 20, and the third display layer 40 is slidably connected to the supporting housing 13.

[0117] The driving assembly 50 is installed in the middle of the base plate 11, and the driving assembly 50 includes a motor 51 and a supporting nut 52;

[0118] The motor 51 is installed in the middle of the base plate 11. The motor 51 has a rotating shaft 511. The surface of the rotating shaft 511 is provided with threads.

[0119] The support nut 52 is threadedly connected to the rotating shaft 511, and a compression space 500 is formed between the rotating shaft 511 and the support nut 52. The side of the support nut 52 away from the rotating shaft 511 is connected to the second display layer 30.

[0120] The lifting assembly 60 is installed on the connecting portion 122, and the lifting assembly 60 includes a cylinder 61 and an elastic member 62;

[0121] The cylinder 61 is mounted on the connecting portion 122, one end of the elastic member 62 is connected to the connecting portion 122, and the other end of the elastic member 62 is connected to the sliding portion 121;

[0122] The support nut 52 is provided with a second air passage 520 connecting the telescopic housing 12 and the compression space 500. The support nut 52 is provided with an air hole 521, through which the third display layer 40 and the compression space 500 are connected. The motor 51 rotates to change the pressure in the compression space 500. The changed pressure in the compression space 500 drives the first display layer 20 and the third display layer 40 to move toward or away from the motor 51 through the second air passage 520.

[0123] A first guide groove 100 is formed between the base plate 11 and the telescopic housing 12. A first air passage 120 connecting the first guide groove 100 and the cylinder 61 is provided in the telescopic housing 12. When the telescopic housing 12 moves away from or toward the driving assembly 50, the pressure in the first guide groove 100 and the first air passage 120 changes to provide a power source to the cylinder 61.

[0124] Among them, the driving component 50 is used to drive the first display layer 20 to move in a direction away from or close to the motor 51 (moving in the length or width direction of the first display layer 20), and the lifting component 60 is used to drive the first display layer 20 to move in a direction perpendicular to the display surface of the first display layer 20 (i.e., moving up and down in the vertical direction).

[0125] The implementation principle of the embodiment of the present application includes: when the display device is in a retracted state (i.e., a small screen state), the electromagnet located on the connecting shell 14 is energized, and the electromagnet is adsorbed on the magnetic metal on the telescopic shell 12. At this time, all components are fixed and present a stable small screen state, and the display state is as follows: Figure 5 As shown;

[0126] When it is necessary to switch to the extended state, the electromagnet on the connecting shell 14 is powered off, the motor 51 is run, the shaft 511 of the motor 51 starts to rotate, and the air in the compression space 500 is compressed by cooperating with the support nut 52. The pressure in the compression space 500 increases, so that the gas flows outward through the air hole 521 and the second air channel 520 on the support nut 52. At this time, the telescopic shell 12 connected to the second air channel 520 will move westward away from the motor 51, and the telescopic shell 12 is connected to the first display layer 20, thereby driving the first display layer 20 to move outward until the first display layer 20 reaches the preset position; at the same time, the gas in the compression space 500 will also squeeze the third display layer 40 through the air hole 521, so that the third display layer 40 moves away from The motor 51 moves in the direction of the telescopic shell 12; since there is a first guide groove 100 between the telescopic shell 12 and the substrate 11, when the telescopic shell 12 and the substrate 11 move relative to each other, the air in the first guide groove 100 will be compressed to provide thrust to the cylinder 61, pushing the first display layer 20 connected to the connecting portion 122 downward until it is pushed to the same plane as the third display layer 40; in addition, since the rotating shaft 511 of the motor 51 is always in selection, and the second display layer 30 is arranged above the supporting nut 52, so under the rotation of the motor 51, after the third display layer 40 moves to a preset position, the second display layer 30 will move downward and be positioned and embedded in the third display layer 40. At this point, the three display layers are in the same plane, together forming a large display screen of the display device, and the display status is as follows Figure 6 The contraction process is the reverse process of the expansion process, and the contraction can be completed by simply reversing the motor 51 and utilizing the pressure reduction and magnetic attraction.
