[0047] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0048] The present disclosure will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, identical elements are represented by similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not all drawn to scale. In addition, certain well-known parts may not be shown in the drawings.

[0049] Many specific details of the present disclosure are described below, such as component structures, materials, dimensions, processing techniques, and technologies, to provide a clearer understanding of the present disclosure. However, as will be appreciated by those skilled in the art, the present disclosure may be implemented without following these specific details.

[0050] The words “first”, “second” and similar terms used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as “include” or “comprise” mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as “connected” or “connected” to two structures and similar terms include not only direct contact between the two structures to achieve connection, but also indirect connection between the two structures through other structures.

[0051] In addition, the term "fixed" between two structures in the present disclosure merely indicates that the two structures are inseparable under a certain state or time, but the two structures may separate under other states or time. For example, when a screw is screwed into a corresponding screw hole, the screw and the screw hole are fixed, but the screw can also be removed from the screw hole to separate the screw and the screw hole.

[0052] In addition, in the expression of the range A to B in the present disclosure, the defined range includes the two endpoint values ​​A and B.

[0053] The spliced ​​display device includes a box body and multiple sub-display panel assemblies assembled on the box body, wherein the sub-display panel assemblies include a display substrate and a bracket structure, the bracket structure has a supporting surface, and the distance between the supporting surface and the box body surface is the supporting height of the bracket structure.

[0054] In actual applications, it is found that after the sub-display panel assembly is assembled to the box, due to factors such as assembly errors during the assembly process, problems such as the support surface of the bracket structure in the currently assembled sub-display panel assembly may occur, and the actual support height of the bracket structure may deviate from the pre-designed support height. As a result, there is a step difference between the support surface of the bracket structure in the currently assembled sub-display panel assembly and the support surface of the bracket structure in the sub-display panel assembly that has been assembled on the box. At this time, the display surface of the display substrate in the currently assembled sub-display panel assembly will not be on the same plane as the display surface of the display substrate in the sub-display panel assembly that has been assembled on the box. When the spliced ​​display device displays the picture, the area where at least two sub-display panel assemblies with the step difference are located will have a concave-convex or split feeling, which greatly affects the overall picture display effect of the spliced ​​display device.

[0055] In the related art, when adjusting the step difference between the support surfaces of the bracket structure, it is necessary to disassemble the entire sub-display panel assembly from the box body, and then reassemble the sub-display panel assembly to the box body to adjust the position of the support surface of the bracket structure in the sub-display panel assembly to eliminate the step difference between the support surface of the bracket structure in the currently assembled sub-display panel assembly and the support surface of the bracket structure in the sub-display panel assembly already assembled on the box body, thereby achieving step difference adjustment. However, this method of adjusting the step difference by reassembly in the related art will result in low assembly efficiency of the spliced ​​display device; in addition, there will inevitably be assembly errors during the reassembly process, making it difficult to accurately adjust the step difference, and the same sub-display panel assembly may be reassembled multiple times.

[0056] Related technologies also propose setting an adjustment mechanism based on magnetism or back top screws on the bracket structure to achieve step adjustment, but it is limited by the complexity of the overall coordination scheme, the difficulty of actual on-site operation, and the limitation of the front and rear adjustment space. At the same time, it is sometimes affected by the back mounting bracket and cannot be effectively adjusted.

[0057] Figure 1 A structural schematic diagram of a bracket structure provided in an embodiment of the present disclosure. Figure 2 It is a cross-sectional schematic diagram of the adjustment structure in the embodiment of the present disclosure. Figure 3 for Figure 2 Schematic diagram of the middle screw extending from the first opening. Figure 4 This is a schematic diagram of adjusting the distance between the support surface of the bracket structure and the surface of the box body by adjusting the structure in the embodiment of the present disclosure. Figures 1 to 4As shown, the bracket structure includes: a bracket body 1 and at least one adjustment structure 6, the bracket body 1 has a support surface 2, an assembly surface 3 and at least one side surface 4, the support surface 2 and the assembly surface 3 are arranged opposite to each other in a first direction X, and the side surface 4 connects the support surface 2 and the assembly surface 3; at least one channel 5 is provided on at least one side surface 4, the extension direction of the channel 5 intersects with the assembly surface 3, and a first channel opening 7 is provided on the assembly surface 3, and the first opening 7 is connected to the corresponding channel 5; the adjustment structure 6 is configured to be able to move along the channel 5 and change the extension amount of the adjustment structure 6 from the assembly surface 3 through the first opening 7 in response to external adjustment.

[0058] In the embodiment of the present disclosure, the support surface 2 on the bracket body 1 is the surface of the bracket body 1 used to support the display substrate. Specifically, the display substrate can be fixed to the support surface. The assembly surface 3 on the bracket body 1 is the surface of the bracket body 1 that faces the housing 30 and is assembled with the housing 30. The two can be assembled with each other, for example, through the cooperation of positioning holes and positioning posts, magnetic fixation, suction cup fixation, etc. The fixing method of the bracket body 1 and the housing 30 is not limited in this disclosure.

[0059] When the position of the support surface 2 of the bracket structure needs to be adjusted to adjust the step difference, it is only necessary to adjust the portion of the adjustment structure 6 located in the hole 5 through the hole 5, so that at least a portion of the adjustment structure 6 can move along the hole 5 and change the amount of extension of the adjustment structure 6 from the assembly surface 3 through the first opening 7; by changing the amount of extension of the adjustment structure 6 from the assembly surface 3, the distance between the assembly surface 3 and the surface of the box 30 at the corresponding position when the bracket structure is assembled with the box 30 can be adjusted, thereby changing the distance between the support surface 2 of the bracket structure and the surface of the box 30, thereby achieving step difference adjustment. Among them, the greater the extension of the adjustment structure 6 from the assembly surface 3, the greater the distance between the assembly surface 3 and the box 30 at the corresponding position; the smaller the extension of the adjustment structure 6 from the assembly surface 3, the smaller the distance between the assembly surface 3 and the box 30 at the corresponding position.

[0060] In the embodiment of the present disclosure, when a step difference problem occurs, the position of the bracket structure can be adjusted without removing the bracket structure from the box body 30, thereby effectively repairing the step difference between the support surfaces 2 of different bracket structures. Compared with the related art, since the step difference adjustment scheme of the present disclosure eliminates the process of "first disassembly and then reassembly", the technical solution of the present disclosure can effectively improve the assembly efficiency of the spliced ​​display device; at the same time, the technical solution of the present disclosure can accurately control the extension amount of the adjustment structure 6 from the assembly surface 3, that is, it can accurately adjust the position of the support surface 2 of the bracket structure, so that the step difference can be accurately adjusted.

[0061] In addition, since the channel 5 is located on the side 4 of the bracket structure, there is no requirement for the front and rear installation environment of the sub-display panel assembly (the space on the side of the display substrate facing away from the bracket structure and the space on the side of the bracket structure facing away from the display substrate) during the process of adjusting the position of the support surface 2 of the bracket structure, so it has strong application capabilities; further, since the channel 5 extends obliquely from the side 4 of the bracket body 1 toward the assembly surface 3, the external jig used to operate the adjustment structure 6 can be obliquely inserted into the channel 5 from the space on the side of the plane where the support surface 2 is located away from the assembly surface 3, and the space for the assembler to operate the external jig can also be located on the side of the plane where the support surface 2 is located away from the assembly surface 3, so the assembler has greater operational control when adjusting the adjustment structure 6 in the channel 5 through the external jig. At the same time, the assembler can intuitively observe the changes in the step difference between the support surface 2 of the adjusted bracket structure and the support surface 2 of other bracket structures during the operation of the external jig, which is conducive to precise adjustment of the step difference.

[0062] Continue to see Figures 2 to 4 As shown, as an optional embodiment, the channel 5 extends from the side surface 4 to the assembly surface 3 in a predetermined extension direction. In other words, the channel 5 directly passes through the side surface 4 and the assembly surface 3 along the predetermined extension direction. In this case, the adjustment structure 6 can move linearly along the channel 5 as a whole, and the extension amount of the adjustment structure 6 from the assembly surface 3 through the first opening 7 can be precisely controlled.

[0063] In some embodiments, the adjustment structure 6 includes a machine screw, and the inner wall of the channel 5 is provided with an internal thread (not shown in the figure) that matches the external thread of the machine screw. The end of the machine screw facing the side 4 is provided with an adjustment slot 6a for adjustment by an external jig. The assembler can engage the external jig with the adjustment slot 6a to control the rotation of the machine screw, thereby controlling the linear motion of the machine screw as a whole along the channel 5.

[0064] Among them, when the machine screw moves along the channel 5 toward the side close to the assembly surface 3, the protrusion of the machine screw from the assembly surface 3 through the first opening 7 increases, and the distance between the assembly surface 3 and the box body at the corresponding position increases; when the machine screw moves along the channel 5 toward the side away from the assembly surface 3, the protrusion of the machine screw from the assembly surface 3 through the first opening 7 decreases, and the distance between the assembly surface 3 and the box body at the corresponding position decreases.

[0065] In some embodiments, the adjustment slot on the machine screw can be a straight slot, a cross slot, a rectangular slot, a hexagonal slot, etc., and the present disclosure does not limit this.

[0066] Figure 5 This is another cross-sectional schematic diagram of the adjustment structure in the embodiment of the present disclosure. Figure 6 for Figure 5 Schematic diagram of the second regulating substructure extending from the first opening. Figure 7 This is another cross-sectional schematic diagram of the adjustment structure in the embodiment of the present disclosure. Figure 8 for Figure 7 Schematic diagram of the second regulating substructure extending from the first opening. Figures 5 to 8 As shown, Figure 2 and Figure 3 Different from the case where the channel 5 directly passes through the side surface 4 and the assembly surface 3 along the preset extension direction, Figure 5 and Figure 7 In the illustrated case, a receiving hole 8 connected to the first opening 7 is formed in the bracket body 1 at a position corresponding to the first opening 7, and the channel 5 is connected to the side wall of the receiving hole 8; the adjustment structure 6 includes: a first adjusting substructure 601 located in the channel 5 and capable of moving along the channel 5 and a second adjusting substructure 602 located in the receiving hole 8 and capable of moving along the receiving hole 8; the first adjusting substructure 601 is configured to move along the channel 5 in response to external adjustment to adjust the extension amount of the first adjusting substructure 601 from the side wall of the receiving hole 8; the second adjusting substructure 602 is configured to contact the portion of the first adjusting substructure 601 extending from the side wall of the receiving hole 8, and move toward or away from the first opening 7 in response to the control of the movement of the first adjusting substructure 601 to adjust the extension amount of the second adjusting substructure 602 from the assembly surface 3 through the first opening 7.

[0067] It should be noted that, in the embodiment of the present disclosure, the receiving hole 8 may be a through hole (eg Figures 5 to 8 ), it can also be a blind hole with a depth less than the width of the bracket side. In the present disclosure, it is only necessary to ensure that the accommodating hole 8 is connected to the first opening.

[0068] In some embodiments, the angle between the extending direction of the receiving hole 8 and the plane where the assembly surface 3 is located is 30° to 90°.

[0069] In the embodiment of the present disclosure, the first adjusting substructure 601 is controlled to move along the channel 5 to control the second adjusting substructure 602 to move in the direction closer to the first opening 7 or away from the first opening 7 in the accommodating hole 8, thereby adjusting the extension amount of the second adjusting substructure 602 from the assembly surface 3 through the first opening 7.

[0070] In some embodiments, when the second adjusting substructure 602 abuts against the portion of the first adjusting substructure 601 extending from the side wall of the accommodating hole 8, if the first adjusting substructure 601 moves along the channel 5 toward the assembly surface 3, the second adjusting substructure 602 moves in the accommodating hole 8 toward the first opening 7, which can increase the amount of the second adjusting substructure 602 extending from the assembly surface 3 through the first opening 7; if the first adjusting substructure 601 moves along the channel 5 toward away from the assembly surface 3, the second adjusting substructure 602 moves in the accommodating hole 8 toward away from the first opening 7, which can reduce the amount of the second adjusting substructure 602 extending from the assembly surface 3 through the first opening 7.

[0071] Compared to Figure 2 In the scheme in which only the channel 5 is provided but no receiving hole 8 is provided, Figures 5 to 8 In the embodiment shown, the first opening 7 may be arranged closer to the edge of the mounting surface 3 .

[0072] See also Figure 5 and Figure 6 As shown, the second regulating substructure 602 includes: a first part close to the first opening 7; in the direction along the first direction X and from the assembly surface 3 to the support surface 2, the cross-sectional area of ​​the first part parallel to the assembly surface 3 gradually increases, and the area of ​​the first opening 7 is smaller than the maximum cross-sectional area of ​​the first part parallel to the assembly surface 3.

[0073] In some embodiments, the cross-sectional area of ​​the receiving hole 8 parallel to the mounting surface 3 gradually increases along the first direction X from the mounting surface 3 toward the support surface 2. This design allows the second adjusting substructure 602 to automatically move away from the first opening 7 due to the squeezing force of the sidewalls as the first adjusting substructure 601 decreases from the sidewalls of the receiving hole 8.

[0074] In some embodiments, the first portion is hemispherical, conical (eg, cone-shaped or pyramid-shaped), or frustum-shaped (eg, truncated cone-shaped or truncated pyramid-shaped).

[0075] In some embodiments, the first portion is hemispherical, and the second regulating substructure 602 is spherical. When the second regulating substructure 602 is designed to be spherical, the lower half of the second regulating substructure 602 is always hemispherical, so there is no need to adjust the posture of the second regulating substructure 602 within the receiving hole 8. As a specific example, the second regulating substructure 602 can be a spherical structure made of stainless steel.

[0076] In some embodiments, a first bayonet structure 10 is formed at the first opening 7. The first opening 7 structure can effectively prevent the second adjusting substructure 602 from falling out of the receiving hole 8, and can also provide a squeeze force on the second adjusting substructure 602 in a direction away from the assembly surface 3, so that when the extension of the first adjusting substructure 601 from the side wall of the receiving hole 8 decreases, the second adjusting substructure 602 is automatically moved in a direction away from the first opening 7 by the squeezing force of the first bayonet structure 10.

[0077] See also Figure 7 and Figure 8 As shown, Figure 5 and Figure 6 Different from the second regulating substructure 602 shown in FIG. Figure 7 and Figure 8 The second adjustment substructure 602 includes: a limiting component 6021, a telescopic rod 6022 and an elastic component 6023, and a second bayonet structure 12 for the telescopic rod 6022 to extend is formed at the first opening 7; the limiting component 6021 is fixed to one end of the telescopic rod 6022 close to the support surface 2, one end of the elastic component 6023 is connected to the limiting component 6021, and the other end of the elastic component 6023 is connected to the second bayonet structure 12; wherein, the elastic component 6023 is in a compressed state.

[0078] When the extension amount of the first adjusting substructure 601 from the side wall of the accommodating hole 8 increases, the first adjusting substructure 601 can push the limiting component 6021 and the telescopic rod 6022 to move along the accommodating groove toward the side close to the assembly surface 3, thereby increasing the extension amount of the telescopic rod 6022 extending through the first opening 7; when the extension amount of the first adjusting substructure 601 from the side wall of the accommodating hole 8 decreases, under the action of the elastic force of the elastic component 6023, the limiting component 6021 and the telescopic rod 6022 are pushed to move along the accommodating groove toward the side away from the assembly surface 3, thereby reducing the extension amount of the telescopic rod 6022 extending through the first opening 7.

[0079] In some embodiments, the accommodating hole 8 includes: a first part 801 and a second part 802 arranged along the first direction X, the first part 801 is located on the side of the second part 802 away from the assembly surface 3, and the channel 5 is connected to the side wall of the first part 801; the cross-sectional area of ​​the limiting component 6021 parallel to the assembly surface 3 is smaller than the cross-sectional area of ​​the first part 801 parallel to the assembly surface 3, the cross-sectional area of ​​the limiting component 6021 parallel to the assembly surface 3 is greater than the cross-sectional area of ​​the second part 802 parallel to the assembly surface 3, and the cross-sectional area of ​​the second part 802 parallel to the assembly surface 3 is greater than the cross-sectional area of ​​the telescopic rod 6022 parallel to the assembly surface 3.

[0080] Continue to see 5 to Figure 8As shown, in some embodiments, the first adjustment substructure 601 includes a machine screw, and the inner wall of the channel 5 is provided with an internal thread (not shown) that matches the external thread of the machine screw. In other words, an external fixture can be inserted into the channel 5 and rotated to control the extension of the machine screw from the side wall of the receiving hole 8.

[0081] In some embodiments, the receiving hole 8 extends from the assembly surface 3 to the support surface 2, and a second opening 9 is formed on the support surface 2. In this case, the receiving hole 8 is a through hole. The provision of the second opening 9 facilitates the placement of the second adjustment substructure 602 in the receiving hole 8.

[0082] Continue to see Figure 2 、 Figure 5 、 Figure 7 As shown, in some embodiments, the angle between the extension direction of the channel 5 and the first direction X is in the range of 20° to 80°. In practical applications, the angle between the extension direction of the channel 5 and the first direction X can be set according to actual needs.

[0083] Figure 9 This is a schematic diagram of the structure of the bracket structure in the corner area in an embodiment of the present disclosure. Figure 10 This is a structural diagram of three bracket structures spliced ​​together in the embodiment of the present disclosure. Figure 9 and Figure 10 As shown, Figure 9 As shown, in some embodiments, the bracket body 1 includes at least one corner area 20, in which a first side surface 4a, a second side surface 4b and a chamfered side surface 11 connecting the first side surface 4a and the second side surface 4b are provided; a channel 5 is provided on the chamfered side surface 11.

[0084] In the embodiment of the present disclosure, by providing a chamfered side surface 11 between the first side surface 4a and the second side surface 4b in the corner area 20, and providing a channel 5 on the chamfered side surface 11, when both the first side surface 4a and the second side surface 4b are blocked by other bracket structures, the assembler can still adjust the position of the support surface of the bracket structure through the channel 5 on the chamfered side surface 11.

[0085] The box includes a mounting surface, which includes multiple areas to be assembled with a bracket structure (sub-display panel assembly) carrying a display substrate, and the multiple areas are distributed in an n*m array; in the process of installing the bracket structure, a row-by-row installation method is often adopted on the mounting surface; as an example, a row-by-row installation method from bottom to top is adopted on the mounting surface. Figure 10For example, in the example shown in FIG, first, bracket structure 100A is installed; then bracket structure 100C is installed on the right side of bracket structure 100A, completing the installation of the lower bracket structure; then, bracket structure 100B is installed on the upper side of bracket structure 100A. At this point, the right side of bracket structure 100A is obscured by bracket structure 100C, and the upper side of bracket structure 100A is obscured by bracket structure 100B. However, the chamfered side surfaces 11 on the upper and right sides of bracket structure 100A (i.e., the first and second sides of the aforementioned corner area) are exposed. The position of the support surface of bracket structure 100A can now be adjusted using the holes 5 on the chamfered side surfaces 11.

[0086] Continue to see Figure 1 As shown, in some embodiments, the bracket body 1 is polygonal, and the bracket body 1 includes a plurality of corner areas 20, each of which is located at the corner of the polygon. Figure 9 As shown, in some embodiments, within the same corner area 20, the first side surface 4a, the second side surface 4b, and the chamfered side surface 11 are all provided with channels 5.
