The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

The application provides a display device and a fine adjustment structure, which are described in detail below. It should be noted that the following description order of the embodiments is not intended to limit the preferred order of the embodiments of the present application. In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.

With rapid development of technology, electronic devices enter the aspects of life of people. In a corporate daily meeting, the intelligent screen 10 is typically used to display the interpreted content for the convenience of content presentation and audience understanding.

Currently, most conference rooms of companies are in a cuboid structure (see fig. 1), wherein a smart screen 10 is fixedly arranged on one wall of the room, and an office desk is arranged in the middle of the room, so that only people facing the smart screen 10 can normally raise their heads to see the screen, and the rest people need to twist their heads to see the screen. When the meeting time exceeds half an hour, people with long-time twisting can feel soreness of the neck, and the screen position cannot be adjusted according to the number of the meeting participants, so that the efficient meeting is not facilitated.

Moreover, since the screen of the conventional intelligent screen 10 is always fixed, the explanation personnel can only explain the intelligent screen for one area, and the display form is relatively single, so that the intelligent screen is not suitable for dynamic demonstration.

In view of this, the embodiments of the present application provide a display device and a fine tuning structure, which can solve the problems of inconvenient viewing for users and single demonstration mode in the prior art, and the following detailed descriptions are respectively provided.

Referring to fig. 2, 3 and 4, fig. 2 is a schematic axial structure of an embodiment of a display device of the present application, fig. 3 is a schematic top structure of an embodiment of a display device of the present application, and fig. 4 is a schematic structure of an embodiment of a guide rail of the present application.

In an embodiment, the display device a may be applied to education, lectures, or other scenes where display is required to display the content for displaying. Specifically, the display apparatus a may include a rail assembly 20, a first display device 30, and a second display device 40. The rail assembly 20 includes a first rail 21 and a second rail 22 connected to each other, and the first rail 21 and the second rail 22 are disposed at an angle. The first display device 30 is slidably coupled to the first rail 21 and the second rail 22, and the second display device 40 is slidably coupled to the first rail 21 and the second rail 22. When the first display device 30 and the second display device 40 are respectively located on different guide rails, the first display device 30 and the second display device 40 may be disposed at an included angle, and when the first display device 30 and the second display device 40 are located on the same guide rail, the first display device 30 and the second display device 40 are disposed in a plane. In other words, the first display device 30 and the second display device 40 can be adjusted to different positions according to different use requirements, that is, the user can adjust the positions of the first display device 30 and the second display device 40 on the guide rail assembly 20 according to the seating situation of the spectator, so as to facilitate the spectator's viewing.

For example, when the viewers are all seated on one side of the desk and the side is directed toward the first guide rail 21, the user can move the first display device 30 and the second display device 40 onto the first guide rail 21, thereby facilitating the viewers' viewing. When the viewers sit on both sides of the desk, the user can move the first display device 30 onto the first guide rail 21, the second display device 40 onto the second guide rail 22, and the first display device 30 and the second display device 40 play the same content, respectively, thereby facilitating the viewers' viewing.

It should be noted that the first guide rail 21 and the second guide rail 22 are used for guiding and fixing the first display device 30 and the second display device 40, and grooves or ridges may be formed on the surfaces of the first guide rail 21 and the second guide rail 22, which are not particularly limited herein. The angle between the first rail 21 and the second rail 22 may be 90 ° or an obtuse angle, and in this embodiment 90 ° is preferably used.

The first display device 30 and the second display device 40 may be two identical or two different display devices, and in this embodiment, the two display devices define the first display device 30 and the second display device 40 respectively, which is only needed for discussion, and not limiting. In practical applications, the first display device 30 and the second display device 40 may be any one of a display screen, a smart screen, and a touch screen.

The display device a described above may have an extended mode and a copy mode. When the display apparatus a is in the extended mode, the same content is played by the first display device 30 and the second display device 40 in cooperation. When the display apparatus a is in the copy mode, the first display device 30 and the second display device 40 play the same content, respectively.

The switching of the expansion mode and the copy mode may be controlled by user selection. Of course, the switching of the expansion mode and the copy mode may be controlled by the positional relationship between the first display device 30 and the second display device 40. Specifically, in one embodiment, a trigger switch (not shown) is installed on a side of the first display device 30 adjacent to the second display device 40, or a trigger switch is installed on a side of the second display device 40 adjacent to the first display device 30. When adjacent sides of the first display device 30 and the second display device 40 are spliced together, the trigger switch sends a first signal, so that the controller controls the display apparatus a to be in the expansion mode. When the first display means 30 and the second display means 40 are separated, the trigger switch transmits a second signal, whereby the display device a is controlled by the controller to be in the copy mode.

Alternatively, the trigger switch may be any one of a proximity sensor, a distance sensor, and a lidar.

The first display device 30 and the second display device 40 can be automatically adjusted to move on the rail assembly 20. In an embodiment, the display apparatus a may further include a driving part 50 and a link 60. One end of the link 60 is hinged with the first display device 30, and the other end of the link 60 is hinged with the second display device 40. The driving part 50 is connected to the first display device 30 to drive the first display device 30 to slide on the first rail 21 or to drive the first display device 30 to slide on both the first rail 21 and the second rail 22. Specifically, when the driving part 50 drives the first display device 30 to slide on the first rail 21, the first display device 30 drives the link 60 to move, so that the link 60 drives the second display device 40 to slide on the second rail 22, or the link 60 drives the second display device 40 to slide on both the first rail 21 and the second rail 22. When the driving part 50 drives the first display device 30 to slide on the first guide rail 21 and the second guide rail 22 simultaneously, the first display device 30 drives the link 60 to move, so that the link 60 drives the second display device 40 to slide on the second guide rail 22. In other words, the driving component 50 can drive the first display device 30 to move, and meanwhile, the connecting rod 60 drives the second display device 40 to move, so that the positions of the first display device 30 and the second display device 40 on the guide rail assembly 20 can be automatically adjusted, the user does not need to participate, and the user experience is improved.

It should be noted that, the driving of the first display device 30 and the second display device 40 by the driving component 50 and the connecting rod 60 can automatically adjust and move on the guide rail assembly 20, compared with the conventional manner that the screen of the intelligent screen 10 is always fixed, the first display device 30 and the second display device 40 of the embodiment can cooperate with the explanation personnel to move, so as to realize dynamic display and enrich the explanation forms.

For convenience of description, the present application limits the driving part 50 to be connected to the first display device 30 and uses the second display device 40 as a driven part. It should be noted that the above limitation is only for the purpose of defining the first display device 30 and the second display device 40 as driving means and driven means, respectively, and it is not intended that the driving means 50 can be connected only to the first display device 30 such that the first display device 30 acts as driving means and the second display device 40 acts as driven means. In fact, the driving part 50 may be connected to the second display device 40, the second display device 40 as a driving part, and the first display device 30 as a driven part in some cases.

In a specific embodiment, the surfaces of the first rail 21 and the second rail 22 may be formed with grooves. Specifically, the first guide rail 21 has a first sliding groove 211, the second guide rail 22 has a second sliding groove 221, the first sliding groove 211 communicates with the second sliding groove 221, and the first sliding groove 211 and the second sliding groove 221 are disposed at an included angle. The first display device 30 is respectively rotatably connected with a first sliding block 31 and a second sliding block 32, the first sliding block 31 and the second sliding block 32 are arranged at intervals along the length direction of the first display device 30, the first sliding block 31 is slidably connected in the first sliding groove 211, and the second sliding block 32 can be slidably connected in the first sliding groove 211 and the second sliding groove 221. That is, the first display device 30 is slidably coupled to the rail assembly 20 through the first slider 31 and the second slider 32 to slidably couple the first display device 30 to the rail assembly 20. Correspondingly, the second display device 40 is rotatably connected with a third sliding block 41 and a fourth sliding block 42 respectively, the third sliding block 41 and the fourth sliding block 42 are arranged at intervals along the length direction of the second display device 40, the third sliding block 41 is slidably connected in the second sliding groove 221, and the fourth sliding block 42 can be slidably connected in the first sliding groove 211 and the second sliding groove 221. That is, the second display device 40 is slidably coupled to the rail assembly 20 through the third slider 41 and the fourth slider 42 to slidably couple the second display device 40 to the rail assembly 20.

In practical applications, the first slider 31 and the second slider 32 may be respectively located at two ends of the side where the first display device 30 is connected to the rail assembly 20, and the third slider 41 and the fourth slider 42 may be respectively located at two ends of the side where the second display device 40 is connected to the rail assembly 20, so that the stability of the connection between the first display device 30 and the second display device 40 and the rail assembly 20 may be further improved. Correspondingly, the included angle between the first sliding groove 211 and the second sliding groove 221 may be 90 ° or an obtuse angle, and 90 ° is preferably used in this embodiment.

It should be noted that, the length direction of the first display device 30 is understood as the length direction of the side of the first display device 30 connected to the rail assembly 20; the length direction of the second display device 40 is understood to be the length direction of the side of the second display device 40 connected to the rail assembly 20.

For the sake of easy understanding, the following description will be given by taking an example in which the driving member 50 is connected to the first display device 30.

In an embodiment, the driving member 50 is connected to the first slider 31 to drive the first slider 31 to move linearly in the first sliding slot 211. For example, the driving part 50 may drive the first slider 31 to perform a linear motion in the first sliding groove 211 using an electric cylinder, an air cylinder, a linear module, or the like.

For example, the driving part 50 may include a driving motor 51, a first screw 52, and a moving end 53. The driving motor 51 is disposed on the first guide rail 21, and the driving motor 51 is connected to the first screw 52 to drive the first screw 52 to rotate. The first screw rod 52 is parallel to the first guide rail 21, and the moving end 53 is screwed on the first screw rod 52 and connected to the first slider 31. Thus, when the driving motor 51 drives the first screw rod 52 to rotate in the forward and reverse directions, the moving end 53 moves linearly along the length direction of the first screw rod 52 under the limitation of the first slider 31, and further drives the first slider 31 to move linearly in the first sliding slot 211.

To ensure that the first display device 30 can slide from the first slide slot 211 onto the second slide slot 221, and that the second display device 40 can slide from the second slide slot 221 onto the first slide slot 211. In an embodiment, on the slide way constituted by the first slide groove 211 and the second slide groove 221, the second slider 32 and the third slider 41 should be located between the first slider 31 and the fourth slider 42, and the second slider 32 and the third slider 41 should be capable of sliding on the first slide groove 211 and the second slide groove 221.

In the present embodiment, the width of the first sliding groove 211 should be identical to the width of the second sliding groove 221. The second slider 32 and the third slider 41 may be cylindrical blocks or square blocks. Preferably, the second slider 32 and the third slider 41 are cylindrical blocks, so that friction of the second slider 32 and the third slider 41 on the first sliding groove 211 and the second sliding groove 221 can be reduced, so that the second slider 32 and the third slider 41 can slide smoothly.

In the above manner, when the driving part 50 drives the first slider 31 to move on the first sliding groove 211, the second slider 32 and the third slider 41 can both slide on the first sliding groove 211 and the second sliding groove 221, thereby enabling the first display device 30 to slide from the first sliding groove 211 onto the second sliding groove 221, and enabling the second display device 40 to slide from the second sliding groove 221 onto the first sliding groove 211, so as to ensure that the first display device 30 and the second display device 40 can realize the functions of displaying at different angles as described above.

It should be noted that, since the first slider 31 is connected to the moving end 53, the first slider 31 is limited to slide within the first sliding slot 211, that is, the first slider 31 does not need to slide from the first sliding slot 211 into the second sliding slot 221, and thus, the specific shape of the first slider 31 is not specifically limited thereto. The fourth slider 42 may slide only in the second sliding groove 221 or may slide from the second sliding groove 221 into the first sliding groove 211, so that the second display device 40 may slide from the second sliding groove 221 to the first sliding groove 211, and thus, the specific shape of the fourth slider 42 is not particularly limited herein.

The rail assembly 20 may be installed on the ground and used as a ground rail such that the first display device 30 and the second display device 40 may be slidably coupled over the rail assembly 20. Of course, the rail assembly 20 may also be used as a hanger rail in a hanging manner, such that the first display device 30 and the second display device 40 are hung on the hanger rail.

The rail assembly 20 is used as a hanger rail as follows. In one embodiment, display device A may also include a stand 70. The bracket 70 is installed on the ground, and the bracket 70 is connected with the rail assembly 20 to raise the rail assembly 20. The first display device 30 and the second display device 40 are suspended on the rail assembly 20.

Referring to fig. 5 and fig. 6, fig. 5 is a schematic cross-sectional structure of an embodiment of a connection portion of a first display device and a guide rail through a first slider, and fig. 6 is a schematic cross-sectional structure of an embodiment of a connection portion of a second display device and a guide rail through a fourth slider.

In an embodiment, the display apparatus a may further include a first fastener 71 and a second fastener 72. The first fastener 71 has two ends, and the first fastener 71 has a large head end and a small head end in terms of the two end diameter dimension of the first fastener 71. Similarly, the second fastener 72 also has a large head end and a small head end.

Wherein, the small end of the first fastening member 71 may be connected with the first display device 30 through the moving end 53, one end of the link 60, the first slider 31, and the first sliding groove 211, respectively. The large end of the first fastener 71 is used to be supported above the moving end 53, the end of the link 60, the first slider 31 and the first sliding slot 211, so that the first display device 30 is hung on the rail assembly 20. It should be noted that the order in which the small end of the first fastener 71 passes through the above-mentioned components is not particularly limited in this embodiment, and the first fastener 71 should be rotatably connected to the moving end 53, one end of the link 60, and the first slider 31.

The small end of the second fastener 72 may be connected to the second display device 40 through the other end of the link 60, the fourth slider 42, and the second chute 221, respectively. The large end of the second fastener 72 is then used to be supported above the other end of the link 60, the fourth slider 42 and the second runner 221 so that the second display device 40 is suspended from the rail assembly 20. It should be noted that the order in which the small end of the second fastener 72 passes through the above-mentioned components is not particularly limited in this embodiment, and the second fastener 72 should be rotatably connected to both the other end of the link 60 and the fourth slider 42.

Considering that adjacent sides of the first display device 30 and the second display device 40 need to be spliced with each other when the display apparatus a is in the extended mode, it is necessary to consider alignment accuracy of the first display device 30 and the second display device 40 when the display apparatus a is installed, so as to avoid that the splice cannot be achieved due to a gap between adjacent sides of the first display device 30 and the second display device 40 when the display apparatus a is in the extended mode, or that adjacent sides of the first display device 30 and the second display device 40 interfere with each other, resulting in damage to the apparatus.

To reduce the difficulty of alignment when the first display device 30 and the second display device 40 are mounted. In an embodiment, the display device a may further comprise a first fine tuning structure 80. The first fine adjustment structure 80 is mounted on the first display device 30, and the first fine adjustment structure 80 is connected with the first fastener 71 for adjusting the distance between the first slider 31 and the second slider 32. In other words, the first fine adjustment structure 80 is used to adjust the position of the first slider 31 in the length direction of the first display device 30. Also, since the first slider 31 and the fourth slider 42 are connected by the link 60, the length of the link 60 is fixed, and when the position of the first slider 31 in the length direction of the first display device 30 is changed, it means that the distance between the first display device 30 and the second display device 40 is changed, that is, the distance between the first display device 30 and the second display device 40 is adjusted, on the slide path formed by the first slide path 211 and the second slide path 221 together.

In this way, the operator can first mount the first display device 30 and the second display device 40 to the rail assembly 20 without considering the alignment accuracy. Then, the distance between the first display device 30 and the second display device 40 may be adjusted by adjusting the first fine adjustment structure 80 after adjusting both the first display device 30 and the second display device 40 onto the first sliding groove 211 or the second sliding groove 221. Therefore, the display device A can be conveniently installed by operators, and the installation level requirement on the operators is reduced.

Referring to fig. 7 and 8, fig. 7 is a schematic top view of an embodiment of a first trimming structure of the present application, and fig. 8 is a cross-sectional view A-A of fig. 7.

With respect to the specific structure of the first trim structure 80. In one embodiment, the first fine adjustment structure 80 may include a base 81, a fifth slider 82, and a second screw 83. The base 81 is connected to the first display device 30, and the base 81 has a vertical portion 811, the vertical portion 811 being perpendicular to the base 81. The fifth slider 82 is slidably connected to the base 81, and a sliding direction of the fifth slider 82 on the base 81 is parallel to a length direction of the first display device 30, and a small end of the first fastener 71 is rotatably connected to the fifth slider 82. One end of the second screw rod 83 passes through the vertical portion 811 and is rotatably connected with the fifth slider 82, the second screw rod 83 is parallel to the sliding direction of the fifth slider 82, two nuts 84 are screwed on the second screw rod 83, and the two nuts 84 are respectively located on two sides of the vertical portion 811.

In this way, after the installation, the user can drive the fifth slider 82 to move through the second screw 83, and adjust the distance between the first slider 31 and the second slider 32, so as to adjust the distance between the first display device 30 and the second display device 40, so that the first display device 30 and the second display device 40 are aligned, and when the display apparatus a is in the extended mode, it is ensured that adjacent sides of the first display device 30 and the second display device 40 can be spliced with each other. When the adjustment is completed, the user can rotate the two nuts 84 such that the two nuts 84 clamp the vertical portions 811 from both sides, respectively, to fix the second screw 83, and thus, the distance between the first display device 30 and the second display device 40, thereby completing the adjustment operation. In practical application, the four corners of the base 81 may be further provided with connection holes, and the base 81 is connected to the first display device 30 through screws passing through the connection holes.

Further, to reduce friction between the small end of the first fastener 71 and the fifth slider 82, wear is reduced, improving the overall service life of the apparatus. In one embodiment, the fifth slider 82 may be coupled to a locking sleeve 86 through a bearing 85. The small end of the first fastener 71 is located within the locking sleeve 86 and is secured within the locking sleeve 86 by a locking screw 87. In this way, the first fastener 71 is connected to the fifth slider 82 through the bearing 85, and the bearing 85 assists the rotation of the first fastener 71, thereby reducing wear.

In an embodiment, the display device a may further comprise a second fine tuning structure 90. The second fine adjustment structure 90 is mounted on the second display device 40, and the second fine adjustment structure 90 is connected with the second fastener 72 to adjust the distance between the fourth slider 42 and the third slider 41.

It should be noted that the second trim structure 90 is identical to the first trim structure 80. The connection manner of the second fine adjustment structure 90 and the second display device 40 and the second fastening member 72 may refer to the connection manner of the first fine adjustment structure 80 and the first display device 30 and the first fastening member 71, and the specific structure will not be described herein.

Referring to fig. 9, fig. 9 is a schematic structural diagram of an embodiment of a conference room of the present application.

Correspondingly, the application also provides a conference room.
