[0047] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] In the related art, the structure of the Mini-LED direct display large screen splicing display device can be as follows Figure 1 As shown, the spliced ​​display device includes a cabinet 01, a connecting piece 02, and a steel structure 03. When installing the spliced ​​display device, the cabinets 01 can be spliced ​​together using screws between the cabinets. The connecting piece 02 is used to fix the cabinets 01 to the steel structure 03 through the back of the cabinets 01. The entire device relies on the steel structure 03 to fix the cabinets 01, thus forming a large-screen spliced ​​display screen.

[0049] However, the use of steel structure 03 increases the cost of engineering materials and labor. The estimated material cost of steel structure 03 is 1000+ / m 2 , plus the on-site installation costs, the cost increase for customers is even higher. At the same time, the steel structure 03 fixes the large-screen splicing display screen, and the cabinets 01 need to be installed one by one on the steel structure 03. During the installation process, in order to ensure the high-quality display effect of the splicing screen (flatness, splicing seams, etc.), the cabinets 01 need to be adjusted while installing, which will lead to a long project delivery time and a significant increase in installation costs. The project installation site requires speed, convenience, and safety. In order to avoid the above problems, how to solve the installation problems of large-screen splicing display devices is of paramount importance to the success of the project.

[0050] In order to solve the above technical problems, the present invention provides a splicing display device, such as Figures 1 to 5 Shown, including:

[0051] Multiple boxes 1 are arranged in an M×N array, and two adjacent boxes 1 in each row of boxes 1 are detachably connected, where M is an integer greater than or equal to 2, and N is an integer greater than or equal to 2. Figure 2 As shown;

[0052] N first mounting portions 2, N first mounting portions 2 correspond to N columns of boxes 1 one by one, each first mounting portion 2 is detachably mounted on one side of a corresponding column of boxes 1, and the first mounting portions 2 and the corresponding column of boxes 1 are arranged along a first direction, which is perpendicular to the row direction and column direction of the boxes 1. Figure 3 and Figure 4 As shown;

[0053] The second mounting portion 3 is used for detachable connection with the wall 9, such as Figure 2 As shown, the first mounting portion 2 can be suspended and matched with the second mounting portion 3;

[0054] N rows of cabinets 1 are sequentially hung on the second mounting portion 3 via the first mounting portion 2 , so that the plurality of cabinets 1 are spliced ​​and arranged in an M×N array.

[0055] The splicing display device provided by the embodiment of the present invention includes a plurality of cabinets 1, N first mounting portions 2 and a second mounting portion 3; the plurality of cabinets 1 are spliced ​​in an M×N array. In the process of splicing the plurality of cabinets 1, the plurality of cabinets 1 can be first divided into N rows for assembly, and the first mounting portion 2 is installed on one side of each row of cabinets 1. Then, the second mounting portion 3 is installed on the wall 9, and then the assembled N rows of cabinets 1 are directly hung on the second mounting portion 3 in sequence. Figures 6 to 7 , and then Figure 2 The assembly process enables the splicing of N rows of cabinets. In the above-mentioned splicing display device, N rows of cabinets 1 are directly hung on the second mounting portion 3 on the wall via the first mounting portion 2. This facilitates operation, reduces installation difficulty, and enables the rapid splicing of multiple cabinets 1. Compared with related technologies, there is no need to assemble the cabinets one by one onto the steel structure. This allows the rapid installation of large-screen splicing without affecting the splicing, solving the problems of low installation efficiency and high labor costs of large-screen splicing display devices.

[0056] In practical applications, the length of each box 1 can be 600 mm, and the width of the box 1 can be 337.5 mm; the boxes 1 are first assembled in rows, and the length of a row of boxes 1 along the row direction of the box array is also 600 mm, so that one person can easily pick up and put them between the hanging parts with one hand, which is quick and convenient, and can achieve rapid installation of the boxes 1.

[0057] For example, Figure 2 In the spliced ​​display device shown, the boxes 1 are spliced ​​and distributed in a 5×5 array. The assembly process of this spliced ​​display device can be:

[0058] First, assemble five boxes 1 into a row. The flatness between the boxes in this row is adjusted to the optimal level during the installation process. Assemble the first installation part 2 of the single row box 1. Figure 3 As shown, the assembly of 5 rows of boxes 1 is completed in sequence;

[0059] Then, install the second mounting portion 3 on the wall, as shown in FIG. Figure 5 As shown;

[0060] Then, five rows of boxes 1 are hung side by side on the hanging bracket 31, as shown in FIG. Figure 6 、 Figure 7 and Figure 2 shown.

[0061] In the embodiment of the present invention, the number of cabinets 1 in the spliced ​​display device is not limited and is determined according to actual conditions.

[0062] In the embodiment of the present invention, the first mounting portion 2 may include P suspension members 21, the P suspension members 21 are arranged at intervals along the second direction, and each suspension member 21 extends along the third direction, P is an integer greater than or equal to 2, the second direction is the column direction of the plurality of boxes 1, and the third direction is the row direction of the plurality of boxes 1. Figure 3 As shown;

[0063] In addition, the second mounting portion 3 may include P suspension brackets 31, the P suspension brackets 31 are arranged at intervals along the second direction, and each suspension bracket 31 extends along the third direction. Figure 5 As shown; wherein, the P suspension members 21 in each first mounting portion 2 can be suspended and matched with the P suspension brackets 31 in the second mounting portion 3 in a one-to-one correspondence.

[0064] In the above-mentioned splicing display device, a row of assembled boxes 1 can be hung on P hanging brackets 31 on the wall through P hanging parts 21. It has a simple structure, is easy to make, and is easy to operate, which reduces the difficulty of installation, can improve the on-site installation efficiency of the device, shorten the project cycle, and save labor costs.

[0065] Specifically, the material of the above-mentioned suspension member 21 can be stainless steel, formed by sheet metal, or can be other materials, which are not limited here.

[0066] The material of the above-mentioned suspension bracket 31 can be stainless steel, formed by sheet metal, or can be other materials, which are not limited here.

[0067] In the present application, the structure in which the suspension member 21 cooperates with the suspension bracket 31 is simple in structure and easy to assemble. Compared with the steel structure in the related art, it can save steel materials and thus save material costs.

[0068] Specifically, the above-mentioned hanging bracket 31 can be fixed to the wall by self-tapping screws, and can also be fixed to the wall by other methods. There is no limitation here, and it depends on the actual situation.

[0069] The specific length of the above-mentioned hanging bracket is not limited here, and the length of the hanging bracket 31 fixed on the wall can be determined according to the length of the spliced ​​display device.

[0070] In the second mounting portion 3 , the distance between two adjacent suspension brackets may not be limited, and the distance between the suspension brackets 31 may be determined based on the distance between the suspension members 21 in the first mounting portion 2 .

[0071] Specifically, the suspension bracket 31 may be of an integrated design.

[0072] Alternatively, the suspension bracket 31 may also include at least two sub-brackets sequentially spliced ​​along the third direction. The suspension bracket 31 can be formed by splicing at least two sub-brackets, which can avoid the problem that the integrated bracket is too long and inconvenient to transport.

[0073] In the embodiment of the present invention, the above-mentioned hanging member 21 can be opposite to the joint of two adjacent boxes 1 in a row of boxes 1, and the hanging member 21 is detachably connected to the edges of the two opposite boxes 1, such as Figure 3 and Figure 4 shown.

[0074] In the above-mentioned splicing display device, the hanging member 21 can be opposite to the splicing point of the two adjacent boxes 1, and the hanging member 21 is connected to the edge of the box 1. The setting position of the hanging member 21 can not affect the flatness of other areas of the box 1, avoid deformation of the hanging member 21, and can ensure the flatness of the splicing of the box 1 and the display effect of the display device.

[0075] Specifically, if Figure 3 As shown, the first mounting portion 2 may have two hanging members 21, one of which may be connected to the joint of the first box and the second box in a row of boxes, and the other hanging member 21 may be connected to the joint of the (N-1)th and Nth boxes in a row of boxes; accordingly, as Figure 5 As shown, the second mounting portion 3 may have two suspension brackets 31 , and the distance between the two suspension brackets 31 may be equal to the distance between the two suspension members 21 in the first mounting portion 2 .

[0076] It should be noted that it is not necessary to set a suspension piece at the joint of every two adjacent boxes in a row of boxes, which can simplify the structure, reduce the difficulty of installation, and improve installation efficiency. The number of suspension pieces 21 assembled on a row of boxes 1 is not limited here and is determined according to actual conditions.

[0077] Optionally, the location of the hanging member 21 on a row of boxes may not be at the joint of two boxes. There is no limitation here and it depends on the actual situation.

[0078] Specifically, the hanging member 21 can be fixedly connected to the box body 1 by screws, which has a simple structure, is easy to assemble, and can speed up the assembly process.

[0079] Optionally, the suspension member 21 may also be connected to the box body 1 in other ways, which are not limited here and depend on actual conditions.

[0080] Specifically, the material of the screw can be carbon steel or other materials, which are not limited here and depend on actual conditions.

[0081] In an embodiment of the present invention, both ends of the suspension member 21 may have hooks 211, and the hooks 211 may be suspended in conjunction with the suspension bracket 31. The hooks 211 may be hung on the suspension bracket 31, and a row of boxes 1 may be directly hung on the suspension bracket 31 through the hooks 211 on the suspension member 21. The structure is simple, easy to manufacture, and easy to operate, and can increase the speed of assembling the box 1 onto the suspension bracket 31.

[0082] In the embodiment of the present invention, both ends of the suspension bracket 31 may have first limiting members 4 , and the first limiting members 4 abut against the ends of the suspension members 21 to limit the movement of the N rows of boxes 1 .

[0083] In the above-mentioned spliced ​​display device, the two ends of the suspension bracket 31 have first limit members 4. When the N columns of cabinets slide to the left or right along the extension direction of the suspension bracket 31, the first limit members 4 at both ends of the suspension bracket 31 can block the sliding of the cabinets, ensuring that the position of the cabinets remains unchanged, and can ensure the stability of the spliced ​​cabinet array, thereby ensuring the stability of the spliced ​​display device.

[0084] During the assembly process of the above-mentioned splicing display device, when the first column of boxes 1 is hung on the suspension bracket 31 through the suspension member 21, the suspension member 21 can be abutted against the first limit member 4 at one end of the suspension bracket 31, and then the other columns of boxes 1 are hung on the suspension bracket 31 in turn. When the last column of boxes 1 is hung, the end of the suspension member 21 on the last column of boxes 1 can be abutted against the first limit member 4 at the other end of the suspension bracket. This can ensure that when the wall vibrates, the N columns of boxes 1 will not slide along the extension direction of the suspension bracket 31.

[0085] Specifically, both ends of the suspension bracket 21 have hooks 211 , and the first position-limiting member 4 on the suspension bracket 31 can abut against the hooks 211 at the ends of the suspension bracket 21 .

[0086] Specifically, on the P suspension brackets 31 of the second mounting portion 3, one of the suspension brackets 31 may have the first position-limiting member 4, or at least two of the suspension brackets 31 may have the first position-limiting member 4.

[0088] Among them, the above-mentioned first limiting member 4 and the suspension bracket 31 can be fixed by screws or by snaps, and the first limiting member 4 can be formed by sheet metal, CNC milling machine, mold, etc.; or, the first limiting member 4 and the suspension bracket 31 can also be integrally formed, which is not restricted here and depends on the actual situation.

[0089] In the embodiment of the present utility model, Figure 10 As shown, at least one second limiting member 5 can also be provided on the above-mentioned suspension bracket 31; the second limiting member 5 can be located between two adjacent rows of boxes 1 and abut against the end of the suspension member 21, and the second limiting member 5 is used to limit the position of the box 1.

[0090] In the above-mentioned spliced ​​display device, a second limiter 5 is provided between two adjacent rows of boxes. When a row of boxes slides along the extension direction of the suspension bracket 31, the second limiter 5 can block the sliding of the boxes, ensuring that the position of the restricted boxes remains unchanged, thereby ensuring the stability of the spliced ​​box array and further ensuring the stability of the spliced ​​display device.

[0091] During the assembly process of the above-mentioned splicing display device, after a row of boxes 1 are assembled onto the second mounting portion 3, in order to prevent this row of boxes 1 from sliding along the hanging bracket 31, a second limiting member 5 is provided on the hanging bracket 31 to limit the box 1. The second limiting member 5 can abut against the end of the hanging member 21 on the row of boxes 1 to prevent the assembled boxes 1 from moving, and then continue to assemble the next row of boxes.

[0092] Specifically, both ends of the suspension bracket 21 have hooks 211 , and the second position-limiting member 5 on the suspension bracket 31 can abut against the hooks 211 at the ends of the suspension bracket 21 .

[0093] Specifically, among the P suspension brackets 31 of the second mounting portion 3, one of the suspension brackets 31 may have the second limiter 5, or at least two suspension brackets 31 may have the second limiter 5. There is no limitation here and it depends on the actual situation.

[0094] Specifically, the material of the second limiting member 5 can be stainless steel, aluminum profile, etc., or other materials, which are not limited here and are determined according to actual conditions.

[0095] Specifically, if Figure 11 As shown, the second position-limiting member 5 may include two sub-plates, which are arranged perpendicularly to each other. One sub-plate is connected to the hanging bracket 31, and the other sub-plate is used to limit the position of the box. The second position-limiting member 5 may be connected to the hanging bracket 31 by screws or by glue, which is not limited here and depends on actual conditions.

[0096] Specifically, if Figure 11 As shown, a screw 6 that abuts against the hanging member 21 can be provided in the area where the second limiting member 5 is opposite to the hanging member 21. The screw 6 can limit the movement of the box body 1. The structure is simple and easy to implement.

[0097] In the embodiment of the present invention, the above-mentioned splicing display device may further include at least one leveling member 7, such as Figure 12 As shown; wherein, the above-mentioned leveling member 7 can be located on the side of the first row of boxes 1 away from the second row of boxes 1, and / or, on the side of the Nth row of boxes 1 away from the (N-1)th row of boxes 1, the leveling member 7 is detachably connected to the two adjacent columns of boxes 1, and the leveling member 7 is used to make the two columns of boxes 1 level.

[0098] In the above-mentioned splicing display device, in order to avoid misalignment of two adjacent rows of cabinets 1 in the column direction of the cabinet 1 array, a leveling member 7 can be set above or below every two rows of cabinets 1. When two rows of cabinets 1 are misaligned in the column direction, the misaligned cabinets 1 can be leveled by the leveling member 7, which can improve the splicing flatness of the splicing display device and enhance the picture quality display effect.

[0099] In the embodiment of the present invention, the leveling member 7 may be a leveling plate, which may be connected to two adjacent rows of boxes 1 by screws. The structure is simple, the adjustment is easy, and the installation efficiency is improved.

[0100] Specifically, the leveling member 7 can be arranged on the side of the first row of boxes 1 away from the second row of boxes 1. When a column of boxes 1 is misaligned with an adjacent column of boxes 1 in the column direction, the lower box 1 can be tightened by screwing screws to lift up the column of boxes 1 to ensure that the two columns of boxes 1 are flush, which can improve the splicing flatness of the device and thereby improve the picture quality display effect of the device.

[0101] Specifically, the leveling member 7 may be made of aluminum alloy or other materials, which are not limited in this example and depend on the actual situation. The leveling member 7 may be formed by a CNC milling machine.

[0102] In the embodiment of the present invention, a gasket may be provided between the hook 211 of at least one hanging member 21 and the hanging bracket 31 , and the gasket is used to raise a row of boxes 1 .

[0103] In the above-mentioned splicing display device, during the splicing process of the boxes 1, when a row of boxes 1 is misaligned with an adjacent row of boxes 1 in the column direction, a gasket can be set between the hook 211 and the suspension bracket 31. The gasket can be used to raise the lower row of boxes 1 to ensure that the two rows of boxes 1 are flush, thereby improving the splicing flatness of the device and thereby improving the image quality display effect of the device.

The four side plates 12 are connected to the four edges of the bottom plate 11. The four side plates 12 and the bottom plate 11 cooperate to form an accommodating space. The first mounting portion 2 may be arranged on a side of the bottom plate 11 away from the accommodating space.

[0105] In the above-mentioned splicing display device, the accommodating space in the box 1 can be used to assemble the display module, the first mounting portion 2 can be arranged on the side of the bottom plate 11 away from the accommodating space, and the two adjacent boxes 1 can be spliced ​​by connecting the side panels 12 of the two boxes 1. The structure is simple and easy to operate.

[0106] Specifically, in each row of boxes 1, the side panels 12 of two adjacent boxes 1 can be fastened and fixedly connected by screws, thereby realizing the splicing between the two boxes 1, which has a simple structure and is easy to operate.

[0107] Specifically, in each row of boxes 1, the side panels 12 have pin holes 121, and the side panels 12 of two adjacent boxes 1 are fixed by tapered positioning screws 8 passing through the pin holes 121.
