To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions according to the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure described herein without paying any creative effort shall be included in the protection scope of the present disclosure.

The words “upper”, “lower”, “left”, “right”, or the like are merely used to indicate a relative positional relationship, and when an absolute position of the described object is changed, the relative positional relationship may be changed accordingly.

With the rapid development of display technology, the tiled display device is more and more widely applied in large-scale places such as markets, cinemas, stadiums and the like, which solves the technical problems of high cost and difficult maintenance of a single large screen, has extremely high expandability and can be suitable for displaying images with various sizes.

The tiled display device includes a plurality of sub-display panel modules and a case, where each of the sub-display panel modules includes a display substrate and a bracket for carrying the display substrate. In the assembly process, a segment difference may be formed between brackets of adjacent sub-display panel modules, and to repair the segment difference, the sub-display panel modules have to be re-installed, which may affect the assembly efficiency of the tiled display device. In addition, poor assembly of the brackets may further cause display tiled seams between adjacent display substrates, affecting flatness of the whole tiled display device and thus causing adverse effects on the display effect.

To solve at least one of the above technical problems, an embodiment of the present disclosure provides a bracket structure configured to adjust a height of a support surface of the bracket structure to adjust the flatness of a plurality of sub-display panel modules in a tiled display device, thereby improving the display effect and the yield of tiled assembly.

FIG. 1 is a schematic structural view of a bracket structure according to an embodiment of the present disclosure, and FIG. 2 is an exploded view of a bracket structure according to an embodiment of the present disclosure. As shown in FIGS. 1 and 2, the bracket structure includes a body 2 and at least one transfer motion adjustor 1.

The body 2 has a support surface 2b, an assembly surface 2a, and at least one side surface. The support surface 2b is disposed opposite to the assembly surface 2a, and the side surface is disposed between the support surface 2b and the assembly surface 2a. The at least one side surface includes a first side surface 2c, and the transfer motion adjustor 1 is located inside the body 2.

The transfer motion adjustor 1 includes: a first rotation member 11 and a first guide member 12 connected to the first rotation member 11. The first rotation member 11 is close to the first side surface 2c. A first hole 41 is provided on the first side surface 2c at a position corresponding to the first rotation member 11, to expose an end of the first rotation member 11 close to the first side surface 2c, so that a first external jig adjusts the first rotation member 11 to rotate through the end of the first rotation member 11 close to the first side surface 2c exposed from the first hole 41.

A second hole 42 is provided on the assembly surface 2a at a position corresponding to the first guide member 12, and the first guide member 12 is configured to move along the second hole 42 in response to the rotational control of the first rotation member 11 to adjust a protruding amount of the first guide member 12 on the assembly surface 2a.

In the bracket structure provided in the embodiments of the present disclosure, first, the first rotation member 11 can be directly adjusted in a rotation manner through the first hole 41 on the first side surface 2c of the bracket structure, so that when the transfer motion adjustor 1 is adjusted, the bracket structure on a side of the support surface 2b of the bracket structure will not interfere with the first hole 41, or affect operation of a first external jig through the first hole 41, thereby improving the adjusting efficiency and convenience in the assembly process; and second, rotation of the first rotation member 11 can drive the first guide member 12 to move to adjust a protruding amount of the first guide member 12 on the assembly surface 2a, and thus adjust a position of the transfer motion adjustor 1, and since the transfer motion adjustor 1 located inside the body 2 of the bracket structure, position adjustment of the bracket structure can be implemented to ensure that display surfaces of the plurality of display substrates in the tiled display device are located in the same plane when spliced, thereby improving the display effect.

It should be noted that, as shown in FIGS. 1 and 2, the bracket structure provided in the embodiment of the present disclosure is configured to support a display panel, and a recess T with a rectangular opening is provided in a central area of the body 2 of the bracket structure, and configured to receive a circuit board connected to the display panel and configured to provide a drive signal for the display panel. The opening shape and size of the recess T can be flexibly set according to the shape/size of the circuit board, which is not limited in the embodiments of the present disclosure.

FIG. 3 is a schematic structural view of a first rotation member according to an embodiment of the present disclosure. In some embodiments, as shown in FIGS. 1 to 3, the first rotation member 11 includes: a first adjusting element 111 and a first connecting element 112 connected to the first adjusting element 111. The first connecting element 112 is located on a side of the first adjusting element 111 away from the first side surface 2c, and the first hole 41 exposes the first adjusting element 111. Optionally, the first adjusting element 111 and the first connecting element 112 are integrally formed.

In some embodiments, the end of the first rotation member 11 close to the first side surface 2c has a cross-section parallel to the first side surface 2c in a first ring shape with a hexagonal inner contour. In other words, the end of the first adjusting element 111 exposed from the first hole 41 has a hexagonal inner contour, so the first external jig used for adjustment may be a hexagonal wrench which is a general assembly tool. Therefore, the assembly and adjustment of the bracket structure are facilitated, adaptability of the bracket structure is improved, and the bracket structure can be adjusted quickly and conveniently in either indoor or outdoor environments.

FIG. 4 is a partial schematic view of a bracket structure according to an embodiment of the present disclosure, and FIG. 5 is a schematic structural view of a transfer motion adjustor according to an embodiment of the present disclosure. In some embodiments, as shown in FIGS. 4 and 5, the first guide member 12 includes a first worm 122 and a first worm wheel 121 nested on the first worm 122. Optionally, the first worm wheel 121 and the first worm 122 are made of the same material.

The first connecting element 112 is provided with first threads 112a, the first worm wheel 121 is provided with engaging insections matched with the first threads 112a, the first worm wheel 121 is configured to rotate in response to rotation of the first connecting element 112, and a rotation axis of the first worm wheel 121 is perpendicular to a rotation axis of the first connecting element 112. As shown in FIG. 4, the rotation axis of the first connecting element 112 is parallel to an extending direction of the first connecting element 112, and a direction perpendicular to the rotation axis of the first connecting element 112 may be a thickness direction Z of the bracket structure. Therefore, while the first connecting element 112 is rotated, the first worm wheel 121 is rotated around the rotation axis of the first worm wheel 121, and moved linearly in the thickness direction Z of the bracket structure. The first worm 122 is provided with second threads, the second hole 42 is provided with internal threads matched with the second threads, and the first worm 122 is configured to rotate coaxially with the first worm wheel 121 to move along the second hole 42 and thus adjust an telescopic amount of the first guide member 12 on the assembly surface 2a of the bracket structure, thereby implementing position adjustment of the bracket structure.

In some embodiments, as shown in FIGS. 2 and 4, a first assembly space 13 is formed inside the body 2 at a position close to the second hole 42 and in communication with the second hole 42, and the first worm 122 and the first worm wheel 121 are both located in the first assembly space 13.

The first guide member 12 further includes: a first elastic component (not shown in the figure) in the first assembly space 13. The first elastic component has one end connected to the first worm wheel 121 and the other end connected to a bottom wall of the first assembly space 13 on a side close to the assembly surface 2a, so that the first guide member 12 is maintained in a stable state when the telescopic amount of the first guide member 12 on the assembly surface 2a of the bracket structure is changed.

The bottom wall of the first assembly space 13 on the side close to the assembly surface 2a refers to a surface of the first assembly space 13 close to the assembly surface 2a; and the second hole 42 communicates from the assembly surface 2a to the bottom wall of the first assembly space 13.

In some embodiments, the first elastic component includes a first spring nested outside the first worm 122. In one example, the first spring may be a preloaded spring, and when the telescopic amount of the first guide member 12 on the bracket structure assembly surface 2a is changed, the first spring provides a preloaded elastic force to ensure stability of the first guide member 12.

It should be noted that the stable state refers to a state in which the first guide member 12 can be smoothly extended or retracted under the action of the first elastic component. When the telescopic amount of the first guide member 12 on the bracket structure assembly surface 2a is changed, an telescopic amount of the first spring is also changed in an opposite direction to the telescopic amount of the first guide member 12, so that the first guide member 12 can be smoothly extended or retracted.

In some embodiments, as shown in FIGS. 2 and 4, the support surface 2b is provided with a first assembly hole 130 communicating from the support surface 2b to the first assembly space 13. The first assembly hole 130 is configured to place the first guide member 12 in the first assembly space 13 during assembly of the transfer motion adjustor 1, and make the first guide member 12 cooperate with the first rotation member 11 assembled to the body 2 of the bracket structure through the first hole 41 to adjust the position of the bracket structure, thereby reducing the assembly difficulty of the transfer motion adjustor and facilitating convenient use of the bracket structure.

In some embodiments, as shown in FIGS. 1, 2, 5 and 6, the first rotation member 11 extends in a first direction X parallel to a plane where the assembly surface 2a is located and intersected with the first side surface 2c, and the first rotation member 11 has a first hollow channel 10 running through the first rotation member 11 in the first direction.

The transfer motion adjustor 1 further includes a second rotation member 21 and a second guide member 22 connected to the second rotation axis. A portion of the second rotation member 21 close to the first side surface 2c is located in the first hollow channel 10, and an end of the first hollow channel 10 close to the first side surface 2c exposes an end of the second rotation member 21 close to the first side surface 2c, so that a second external jig adjusts the second rotation member 21 to rotate through the end of the second rotation member 21 close to the first side surface 2c exposed from the first hollow channel 10. Since the first hole 41 is provided on the first side surface 2c at the position corresponding to the first rotation member 11, to expose the end of the first rotation member 11 close to the first side surface 2c, and the portion of the second rotation member 21 close to the first side surface 2c is located in the first hollow channel 10 of the first rotation member 11, the end of the second rotation member 21 close to the first side surface 2c is also exposed from the first hole 41. In other words, both the first rotation member 11 and the second rotation member 21 can be adjusted through the first hole 41.

As shown in FIGS. 1 and 2, a fourth hole 44 is provided on the assembly surface 2a at a position corresponding to the second guide member 22, and the second guide member 22 is configured to move along the fourth hole 44 in response to the rotational control of the second rotation member 21 to adjust a protruding amount of the second guide member 22 on the assembly surface 2a, so that position adjustment of the bracket structure can be implemented to ensure that display surfaces of the plurality of display substrates in the tiled display device are located in the same plane when spliced, thereby improving the display effect.

In some embodiments, as shown in FIGS. 6 to 8, the end of the second rotation member 21 close to the first side surface 2c has a cross-section parallel to the first side surface 2c in a second ring shape with a hexagonal inner contour. In other words, the end of the second adjusting element 211 exposed from the first hole 41 has a hexagonal inner contour, therefore, similar to the first external jig, the second external jig used for adjusting the second adjusting element 211 may also be a hexagon wrench, which can facilitate assembly and/or adjustment the bracket structure, and improve adaptability of the bracket structure.

It should be noted that since the portion of the second rotation member 21 close to the first side surface 2c is located in the first hollow channel 10 of the first rotation member 11, and the end of the first hollow channel 10 close to the first side surface 2c exposes the second adjusting element 211, the first ring shape has a diameter larger than the second ring shape. Furthermore, the first external jig matched with the inner contour of the first ring shape has greater specifications than the second external jig matched with the inner contour of the second ring shape.

In some embodiments, as shown in FIGS. 1, 6, and 7, the second guide member 22 includes a second worm 222 and a second worm wheel 221 nested on the second worm 222. Optionally, the second worm 222 and the second worm gear 221 are made of the same material.

Therefore, while the second connecting element 212 is rotated, the second worm wheel 221 is rotated around the rotation axis of the first worm wheel 121, and moved linearly in the thickness direction of the bracket structure. The second worm 222 is provided with fourth threads, the fourth hole 44 is provided with internal threads matched with the fourth threads, and the second worm 222 is configured to rotate coaxially with the second worm wheel 221 to move along the fourth hole 44 and thus adjust an telescopic amount of the second guide member 22 on the assembly surface 2a of the bracket structure, thereby implementing flatness adjustment of the support surface 2b of the bracket structure.

In some embodiments, as shown in FIGS. 1 and 6, a second assembly space 23 is formed inside the body 2 at a position close to the fourth hole 44 and in communication with the fourth hole 44, and the second worm 222 and the second worm wheel 221 are both located in the second assembly space 23.

The bottom wall of the fourth hole 44 to which the second assembly space 23 is close refers to a surface in the second assembly space 23 parallel to the assembly surface 2a or the support surface 2b, in which the second hole 44 is defined.

In some embodiments, the second elastic component includes a second spring nested outside the second worm 222. In one example, the second spring may be a preloaded spring, and when the telescopic amount of the second guide member 22 on the bracket structure assembly surface 2a is changed, the second spring provides a preloaded elastic force to ensure stability of the second guide member 22.

In some embodiments, as shown in FIGS. 1, 2, and 6, the support surface 2b is provided with a second assembly hole 230 in communication with the second assembly space 23. The second assembly hole 230 is configured to place the second guide member 22 in the second assembly space 23 during assembly of the transfer motion adjustor 1, and make the second guide member 12 cooperate with the second rotation member 21 assembled to the body 2 of the bracket structure through the first hole 41 to adjust the position of the bracket structure, thereby reducing the assembly difficulty of the transfer motion adjustor and facilitating convenient use of the bracket structure.

In the transfer motion adjustor 1, the first adjusting element 111 on the first rotation member 11 and the second adjusting element 211 on the second rotation member 21 are both exposed from the first hole 41. Therefore, an external jig can be used to adjust either of the rotation members through the first hole 41 on the first side surface 2c. Meanwhile, the first guide member 12 and the second guide member 22 are located at two corners of the bracket structure, so that in the adjusting process, the telescopic amount of one of the guide members on the assembly surface 2a can be adjusted adaptively according to a state of the support surface 2b of the bracket structure, or the first guide member 12 and the second guide member 22 may be adjusted to have different telescopic amounts on the assembly surface 2a of the bracket structure. To sum up, in the bracket structure provided in the embodiments of the present disclosure, one side of the support surface 2b close to the first side surface 2c and the other side away from the first side surface 2c can be adjusted differently through the first hole 41 to increase the flexibility in adjustment of the bracket structure, so as to adjust the position of the bracket structure to ensure that display surfaces of the plurality of display substrates in the tiled display device are located in the same plane when spliced, thereby improving the display effect.

In this case, the first hole 41 on the first side surface 2c of the bracket structure 1-1 is shielded by the bracket structure 2-1, making it impossible to adjust the exposed first adjusting element 111 and second adjusting element 211 through the first hole 41 to adjust flatness of the bracket structure 1-1.

On this basis, in the bracket structure according to the embodiments of the present disclosure, the transfer motion adjustor 1 further includes a third rotation member 31.

FIG. 11 is a schematic structural view of another bracket structure according to an embodiment of the present disclosure. In some embodiments, as shown in FIGS. 2 and 11, the second rotation member 21 extends in the first direction and has a second hollow channel 20 running through the second rotation member 21 in the first direction.

The transfer motion adjustor 1 further includes a third rotation member 31, and the at least one side surface further includes: a third side surface 2d opposite to the first side surface 2c in the first direction. A third hole 43 is provided on the third side surface 2d at a position corresponding to the third rotation member 31 to expose an end of the third rotation member 31 close to the third side surface 2d, and configured to allow an end of the third rotation member 31 away from the first side surface 2c to extend out of the third hole 43.

A portion of the third rotation member 31 close to the first side surface 2c is located in the second hollow channel 20, and an end of the second hollow channel 20 close to the first side surface 2c exposes an end of the third rotation member 31 close to the first side surface 2c, so that a third external jig pushes the third rotation member 31 to extend out of the third hole 43 and adjusts the third rotation member 31 to rotate through the end of the third rotation member 31 close to the first side surface 2c exposed from the second hollow channel 20.

The end of the third rotation member 31 away from the first side surface 2c is configured to be extendable into the first hole 41 of a further bracket structure, and engaged with the end of the first rotation member 11 close to the first side surface 2c exposed from the first hole 41 in the further bracket structure in a direction parallel to the first side surface 2c.

For any one of the plurality of bracket structures, the third side surface 2d is disposed opposite to the first side surface 2c, and since the third side surface 2d is provided with the third hole 43 on the end of the third rotation member 31 close to the third side surface 2d, and the end of the third rotation member 31 close to the first side surface 2c is exposed from the second hollow channel 20, i.e., exposed from the first hole 41, the third hole 43 in the third side surface 2d and the first hole 41 in the first side surface 2c are also disposed opposite to each other.

FIG. 12 is a schematic structural view of a region A in FIG. 9, where the region A is a tiled region between two adjacent brackets. As shown in FIG. 12, on the premise that the first hole 41 and the third hole 43 are disposed opposite to each other on the bracket structure, the first hole 41 in the bracket structure 1-1 is shielded by the bracket structure 2-1. FIG. 13 is a partial schematic view of a multi-bracket structure. As shown in FIGS. 12 and 13, a third external jig is used to push an end of the third rotation member 31 of the bracket structure 2-1 close to the first side surface 2c, to drive an end of the third rotation member 31 close to the third side surface 2d to extend out of the third hole 43 into the first hole 41 of the bracket structure 1-1 and engage with an end of the first rotation member 11 of the bracket structure 1-1 close to the first side surface 2c, i.e., the first adjusting element 111 of the bracket structure 1-1.

In the above adjustment mode, the third connecting element 312 of the bracket structure 2-1 is equivalent to be used to adjust the structural member of the bracket structure 1-1, so an outer contour of an end of the third rotation member 31 of the bracket structure 2-1, close to the third side surface 2d can extend into the first hole 41 of the bracket structure 1-1 to be adapted to an inner contour of the first adjusting element 111 of the bracket structure 1-1 for control and adjustment, so that in the process of adjusting the flatness of the plurality of bracket structures, the assembled bracket structures can be adjusted without being disassembled repeatedly, thereby avoiding a segment difference between adjacent bracket structures, implementing flatness adjustment of the support surface of the bracket structure, and improving the display effect of the tiled display device.

In some embodiments, as shown in FIGS. 11, 12, and 14, the third rotation member 31 includes: a third adjusting element 311 and a third connecting element 312 connected to the third adjusting element 311. The third connecting element 312 is located on a side of the third adjusting element 311 away from the first side surface 2c, the third adjusting element 311 is located in the second hollow channel 20, the third adjusting element 311 extends beyond the second hollow channel 20, an end of the second hollow channel 20 close to the first side surface 2c exposes the third adjusting element 311, and an end of the third connecting element 312 away from the first side surface 2c is extendable from the corresponding third hole 43.

In some embodiments, the end of the third rotation member 31 close to the first side surface 2c has a cross-section parallel to the first side surface 2c in a third ring shape with a hexagonal inner contour.

It should be noted that since the portion of the third rotation member 31 close to the first side surface 2c is located in the second hollow channel 20, and the end of the second hollow channel 20 close to the first side surface 2c exposes the third adjusting element 311, the second ring shape has a diameter larger than the third ring shape, and further, the second external jig matched with the inner contour of the second ring shape has greater specifications than the third external jig matched with the inner contour of the third ring shape.

FIG. 15 is a partial schematic view of a transfer motion adjustor according to an embodiment of the present disclosure. In some embodiments, as shown in FIGS. 2 and 15, the end of the first rotation member 11 close to the first side surface 2c has a cross-section parallel to the first side surface 2c in a first ring shape with a hexagonal inner contour, and the end of the third rotation member 31 away from the first side surface 2c has a cross-section parallel to the first side surface 2c in a hexagonal shape, so that the end of the first rotation member 11 close to the first side surface 2c is engaged with the first adjusting element 111 of a further bracket structure in a direction parallel to the first side surface 2c.

FIG. 16 is a schematic structural view of another bracket structure according to an embodiment of the present disclosure. In some embodiments, as shown in FIGS. 14 to 16, the third rotation member 31 further includes: a location-limited element 313 and a third elastic component 314. A third assembly space 32 is formed inside the body 2 at a position close to the third hole 43 and in communication with the third hole 43. The location-limited element 313 is located in the third assembly space 32, and fixed to a portion of the third connecting element 312 outside the second hollow channel 20. The third elastic component 314 is located in the third assembly space 32, having one end connected to the location-limited element 313 and the other end connected to a side wall of the third assembly space 32 close to the third hole 43.

The third assembly space 32 is configured to receive the location-limited element 313 and the third elastic component 314 on the third rotation member 31, and during assembly, the location-limited element 313 and the third elastic component 314 may be fitted into the body 2 of the bracket structure through the third hole 43 in communication with the third assembly space 32.

In some embodiments, as shown in FIGS. 7 and 14, the elastic component includes a third spring nested on an exterior 312a of a portion of the third connecting element 312 in the third assembly space 32. In an example the same as that shown in FIG. 9, as shown in FIG. 13, when the first rotation member 11 of the bracket structure 1-1 is rotated through the third rotation member 31 of the bracket structure 2-1, an end of the third rotation member 31 of the bracket structure 2-1 close to the third side surface 2d of the bracket structure 2-1 is desired to be extended into the first hole 41 of the bracket structure 1-1, and after the adjustment is completed, a force in the first direction X is applied to an end of the third rotation member 31 of the bracket structure 2-1 close to the first side surface 2c of the bracket structure 2-1, and based on the cooperation of the elastic component and the location-limited element 313, the end of the third rotation member 31 of the bracket structure 2-1 close to the third side surface 2d of the bracket structure 2-1 may be retracted into the body 2 of the bracket structure 2-1, so that the third rotation member 31 of the bracket structure 2-1 is reset. In other words, after the assembly/adjustment is completed, there is no physical connection between any adjacent bracket structures caused by any component on the transfer motion adjustor 1, so as to avoid damage to the tiled display device.

Since the portion of the second rotation member 21 close to the first side surface 2c is located in the first hollow channel 10, and the portion of the third rotation member 31 close to the first side surface 2c is located in the second hollow channel 20, it means that the first connecting element 112 is nested on the second connecting element 212, and the second connecting element 212 is nested on the third connecting element 312.

As shown in FIG. 2, the lower left part of FIG. 2 provides an exploded view of the transfer motion adjustor 1, and the upper right part of FIG. 2 shows a fourth assembly space 1A for placing the transfer motion adjustor 1.
