Description

Technical Field

[0001] The present application belongs to the field of display technology, and in particular, relates to a box body and a display device for a display module. Background Art

[0002] In the related art, the display module of the display device is arranged on a bracket, and the bracket limits the seam during splicing by cooperating the positioning column of the bracket with the positioning hole of the box, and the bracket is fixed to the box by magnetic attraction. If the gap reserved between the positioning hole and the positioning column is large, although the bracket and the box can be easily disassembled, the seam effect of the display module on the bracket is poor; if the gap reserved between the positioning hole and the positioning column is small, the disassembly and assembly of the bracket will be relatively difficult, and it is easy to cause bumps and other problems. At the same time, if the magnetic attraction between the bracket and the box is large, the disassembly and assembly of the bracket and the box will be more difficult; if the magnetic attraction between the bracket and the box is small, the suction force of the box on the bracket is insufficient, and the bracket is easy to fall off; in addition, regardless of the size of the magnetic attraction, after a certain period of time after the splicing display device is installed, the display module will sink due to its own gravity, and the sinking degree of each display module in the splicing display device is different, resulting in a poor splicing effect of the splicing display device, pixel displacement, and poor display effect.

[0046] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0047] The present application embodiment provides a box 100, such as Figures 1 to 7As shown, the box 100 is used to install the bracket 300 of the splicing display device. The box 100 includes a bottom plate 110, a frame assembly 120 and an adjustment assembly 200. The first side surface of the bottom plate 110 is provided with a positioning groove 130; the frame assembly 120 is arranged around the circumferential side surface of the bottom plate 110; the adjustment assembly 200 includes a first adjustment member 210 and a second adjustment member 220; the first adjustment member 210 is arranged on the frame assembly 120 or the positioning groove 130, so that the first adjustment member 210 is arranged along the first direction F1 with the setting The bracket 300 on the first side surface of the base plate 110 abuts, and the first direction F1 is parallel to the base plate 110; the second adjusting member 220 is arranged on the frame assembly 120 or the positioning groove 130, so that the second adjusting member 220 abuts against the bracket 300 along the second direction F2, and the second direction F2 is parallel to the base plate 110 and perpendicular to the first direction F1; wherein, when the first side surface is perpendicular to the horizontal plane, the first direction F1 is parallel to the horizontal plane, and the second adjusting member 220 at least abuts against the lower side of the bracket 300 in the vertical direction F5.

[0048] In the box 100 proposed in the embodiment of the present application, as Figure 3 and Figure 5 As shown, the first adjusting member 210 in the adjusting assembly 200 abuts against the bracket 300 along the first direction F1, and the splicing gap P0 between two adjacent brackets 300 and / or the relative position of the bracket 300 and the box body 100 can be adjusted in the first direction F1, so that the splicing gap P0 between two adjacent brackets 300 arranged in parallel along the first direction F1 and / or the relative position of the bracket 300 and the box body 100 meet the display requirements; the second adjusting member 220 in the adjusting assembly 200 abuts against the bracket 300 along the second direction F2, and when the first side surface is perpendicular to the horizontal plane, that is, when the box body 100 and the bracket 300 installed on the box body 100 are in a vertical state, the second adjusting member 220 at least abuts against the vertical position of the bracket 300 The lower side of the vertical direction F5 is provided so that the second adjusting member 220 can adjust the splicing gap P0 between two adjacent brackets 300 and / or the relative position of the bracket 300 and the box body 100 in the second direction F2, so that the splicing gap P0 between two adjacent brackets 300 arranged side by side along the second direction F2 and / or the relative position of the bracket 300 and the box body 100 meet the display requirements; and can also be supported on the lower side of the vertical direction F5 of the bracket 300 to prevent the bracket 300 from sinking relative to the box body 100, and to prevent the bracket 300 and the display module 400 arranged on the bracket 300 from sinking together, so that the splicing display device maintains good splicing effect and display effect, and avoids pixel deviation, poor display effect and other defects.

[0049] In the box 100 proposed in the embodiment of the present application, by adjusting the position of the first adjusting member 210 and the box 100, the first adjusting member 210 can be brought into contact with the bracket 300 and push the bracket 300 to move in the first direction F1, so that the relative position of the bracket 300 and the box 100 can be adjusted, so that the splicing gap P0 between two adjacent brackets 300 arranged in parallel along the first direction F1 can be reduced to meet the display requirements. When the second adjusting member 220 is only arranged on the lower side of the bracket 300 in the vertical direction F5, by adjusting the position of the second adjusting member 220 and the box 100, the second adjusting member 220 can be brought into contact with the bracket 300 and push the bracket 300 to move in the second direction F2. When the first side surface is perpendicular to the horizontal plane, that is, the box 100 and the bracket 300 are in a vertical state and have a tendency to move vertically downward under the influence of gravity, the bracket 300 can move downward in the second direction F2 / vertical direction F5 under the action of gravity, and can also move downward in the second direction F2 / vertical direction F5 under the action of gravity. 20, it moves upward in the second direction F2 / vertical direction F5, so that the splicing gap P0 between two adjacent brackets 300 arranged in parallel along the second direction F2 is reduced to meet the display requirements through the cooperation of the second adjusting member 220 and gravity. At the same time, the second adjusting member 220 is supported on the lower side of the bracket 300 in the vertical direction F5 to prevent the bracket 300 from sinking relative to the box body 100, and to prevent the bracket 300 and the display module 400 arranged on the bracket 300 from sinking together, so that the splicing display device maintains good splicing effect and display effect. In addition, when the second adjusting member 220 is simultaneously arranged on the upper and lower sides of the bracket 300 in the vertical direction F5, by adjusting the position of the second adjusting member 220 and the box body 100, the second adjusting member 220 can be brought into contact with the bracket 300 and push the bracket 300 to move in the second direction F2. When the first side surface is perpendicular to the horizontal plane, that is, the box body 100 and the bracket 300 are in a vertical state and have a tendency to move vertically downward under the influence of gravity, the bracket 300 can move in the second direction F2 / vertical direction F5 under the action of gravity or the action of the second adjusting member 220. It can move downward, and at the same time, it can move upward in the second direction F2 / vertical direction F5 under the action of the second adjusting member 220, so that the splicing gap P0 between two adjacent brackets 300 arranged in parallel along the second direction F2 can be reduced through the second adjustment to meet the display requirements. At the same time, the second adjusting member is supported on the lower side of the bracket 300 in the vertical direction F5 to prevent the bracket 300 from sinking relative to the box body 100, and to prevent the bracket 300 and the display module 400 arranged on the bracket 300 from sinking together, so that the splicing display device maintains good splicing effect and display effect.

[0050] In the box 100 proposed in the embodiment of the present application, by setting the adjustment component 200, the splicing gap P0 between the brackets 300 can be conveniently adjusted and the bracket 300 can be prevented from sinking; at the same time, the positioning gap between the bracket 300 and the box 100 can be appropriately increased to facilitate the positioning and installation between the bracket 300 and the box 100, and the magnetic attraction force between the bracket 300 and the box 100 can be appropriately reduced. While reducing the difficulty of disassembly and assembly between the bracket 300 and the box 100, the support function of the second adjustment member 220 replaces the magnetic attraction function to prevent the bracket 300 from falling off.

[0051] In the box 100 proposed in the embodiment of the present application, the adjustment component 200 can be applicable to both the die-cast integrated box 100 and the separate box 100; that is, it can be applied to both front installation and debugging and rear installation and debugging, and the operation is simple and convenient.

[0052] In the box 100 proposed in the embodiment of the present application, it can be ensured that the splicing display device has a good splicing effect, especially it can ensure that the splicing display device with a larger size maintains a good splicing display effect, avoid the risk of individual display modules 400 of the splicing display device sinking and causing the display effect to deteriorate, and can meet the splicing requirements of splicing display devices with higher requirements and larger sizes.

[0053] In the box 100 proposed in the embodiment of the present application, optionally, the first adjustment member 210 provided on the frame assembly 120 and / or the positioning groove 130 may include different adjustment precisions. For example, the first adjustment member 210 may include a coarse adjustment mode and a fine adjustment mode, and the coarse adjustment mode may be used to perform coarse adjustment first, so that the bracket 300 is initially moved to a preset position in the first direction F1, so that the splicing gap P0 between two adjacent brackets 300 is initially reduced in the first direction F1, and then the fine adjustment mode may be used to perform fine adjustment, so that the splicing gap P0 between two adjacent brackets 300 in the first direction F1 is further reduced to meet the display requirements. For another example, the first adjustment member 210 may include a first adjustment member 210 for coarse adjustment and a first adjustment member 210 for fine adjustment, and the first adjustment member 210 for coarse adjustment and the first adjustment member 210 for fine adjustment are simultaneously arranged on the frame assembly 120 and / or the positioning groove 130. The first adjustment member 210 for coarse adjustment may be used to perform coarse adjustment first, so that the bracket 300 is preliminarily moved to a preset position in the first direction F1, so that the splicing gap P0 between two adjacent brackets 300 adjusted in the first direction F1 is preliminarily reduced, and then the first adjustment member 210 for fine adjustment is used to perform fine adjustment, so that the splicing gap P0 between two adjacent brackets 300 adjusted in the first direction F1 is further reduced to meet the display requirements. By adjusting the coarse adjustment and the fine adjustment with different degrees of precision, the adjustment effect and adjustment accuracy of the first adjustment member 210 may be improved.

[0054] In the box 100 proposed in the embodiment of the present application, optionally, the second adjustment member 220 provided on the frame assembly 120 and / or the positioning groove 130 may include different adjustment precisions. For example, the second adjustment member 220 may include a coarse adjustment mode and a fine adjustment mode, and the coarse adjustment mode may be used to perform coarse adjustment first, so that the bracket 300 is preliminarily moved to a preset position in the second direction F2, so that the splicing gap P0 between two adjacent brackets 300 in the second direction F2 is preliminarily reduced, and then the fine adjustment mode may be used to perform fine adjustment, so that the splicing gap P0 between two adjacent brackets 300 in the second direction F2 is further reduced to meet the display requirements. For another example, the second adjustment member 220 may include a second adjustment member 220 for coarse adjustment and a second adjustment member 220 for fine adjustment. The second adjustment member 220 for coarse adjustment and the second adjustment member 220 for fine adjustment are simultaneously arranged on the frame assembly 120 and / or the positioning groove 130. The second adjustment member 220 for coarse adjustment may be used to perform coarse adjustment first, so that the bracket 300 is initially moved to a preset position in the second direction F2, so that the splicing gap P0 between two adjacent brackets 300 adjusted in the second direction F2 is initially reduced, and then the second adjustment member for fine adjustment is used to perform fine adjustment, so that the splicing gap P0 between two adjacent brackets 300 adjusted in the second direction F2 is further reduced to meet the display requirements. By adjusting the coarse adjustment and the fine adjustment with different degrees of fineness, the adjustment effect and adjustment accuracy of the first adjustment member 210 may be improved. Based on the same inventive concept, the embodiment of the present application also proposes a splicing display device, such as Figures 1 to 7 As shown, the spliced ​​display device includes the above-mentioned box 100, at least two brackets 300 and at least two display modules 400, wherein the bracket 300 is arranged on the first side of the bottom plate 110; the display module 400 is arranged on the side of the bracket 300 away from the bottom plate 110.

[0055] Since the spliced ​​display device provided by the present invention includes the cabinet 100 of the above technical solution, the spliced ​​display device provided by the present invention has all the beneficial effects of the above cabinet 100, which will not be described in detail here.

[0056] In the following embodiments of the present application, a spliced ​​display device provided with a Mini LED display module 400 is taken as an example to exemplify the box 100 of the present application and the adjustment component 200 therein.

[0057] In some embodiments, Figures 1 to 7As shown, the box body 100 includes a bottom plate 110 and a frame assembly 120, wherein a positioning groove 130 is provided on the first side of the bottom plate 110, and the positioning groove 130 can be used to position the bracket 300 and the box body 100; the frame assembly 120 is surrounded by the circumferential side of the bottom plate 110, thereby forming an internal space of the box body 100 on the first side of the bottom plate 110 for setting the positioning groove 130 and the adjustment assembly 200.

[0058] In some embodiments, Figures 1 to 7 As shown, the two display modules 400 are arranged in parallel along the first direction F1 on the side of the bracket 300 away from the bottom plate 110, and the two brackets 300 are arranged in parallel along the first direction F1 on the first side of the bottom plate 110 of the box body 100. The splicing gap P0 between two adjacent brackets 300 in the first direction F1 can be adjusted by the first adjusting member 210, and the position of the bracket 300 relative to the box body 100 in the second direction F2 can be adjusted by the second adjusting member 220. At the same time, when the display surface of the spliced ​​display device is perpendicular to the horizontal plane, that is, when the box body 100, the bracket 300 and the display module 400 are in a vertical state, the second adjustment member 220 is supported on the lower side of the bracket 300 in the vertical direction F5, which can prevent the bracket 300 and the display module 400 arranged on the bracket 300 from sinking relative to the base plate 110, and avoid some of the bracket 300 and the display module 400 arranged on the bracket 300 from moving downward along the vertical direction F5 relative to the base plate 110, resulting in pixel deviation and poor display effect.

[0059] In other embodiments, the splicing display device may further include a box 100, a plurality of brackets 300, and a plurality of display modules 400. The plurality of display modules 400 are arranged in an array on a side of the bracket 300 away from the bottom plate 110 along the first direction F1 and the second direction F2, and the plurality of brackets 300 are arranged in an array on a first side surface of the bottom plate 110 of the box 100 along the first direction F1 and the second direction F2, and the splicing gap P0 between two adjacent brackets 300 in the first direction F1 can be adjusted by the first adjusting member 210, and the splicing gap P0 between two adjacent brackets 300 in the second direction F2 can be adjusted by the second adjusting member 220. At the same time, when the display surface of the spliced ​​display device is perpendicular to the horizontal plane, that is, when the box body 100, the bracket 300 and the display module 400 are in a vertical state, the second adjustment member 220 is supported on the lower side of the bracket 300 in the vertical direction F5, which can prevent the bracket 300 and the display module 400 arranged on the bracket 300 from sinking relative to the base plate 110, and avoid some of the bracket 300 and the display module 400 arranged on the bracket 300 from moving downward along the vertical direction F5 relative to the base plate 110, resulting in pixel deviation and poor display effect.

[0060] In some embodiments, Figures 1 to 3As shown, the first adjusting member 210 and the second adjusting member 220 in the adjusting assembly 200 are both disposed on the frame assembly 120 .

[0061] like Figures 1 to 3 As shown, the first adjusting member 210 is arranged on the frame assembly 120 along the first direction F1. The first adjusting member 210 abuts against the bracket 300 along the first direction F1, so that the bracket 300 can be pushed to move in the first direction F1, so that the setting position of the bracket 300 relative to the base plate 110 can be adjusted in the first direction F1, and the splicing gap P0 between two adjacent brackets 300 can also be adjusted in the first direction F1, and finally the splicing accuracy of the splicing display device in the first direction F1 meets the display effect requirements.

[0062] like Figures 1 to 3 As shown, the second adjustment member 220 is arranged on the frame assembly 120 along the second direction F2. The second adjustment member 220 abuts against the bracket 300 along the second direction F2, so that the bracket 300 can be pushed to move in the second direction F2, so that the setting position of the bracket 300 relative to the base plate 110 can be adjusted in the second direction F2, and the splicing gap P0 between two adjacent brackets 300 can also be adjusted in the second direction F2, and finally the splicing accuracy of the splicing display device in the second direction F2 meets the display effect requirements.

[0063] like Figure 2 and Figure 3 As shown, when the display surface of the spliced ​​display device is perpendicular to the horizontal plane, that is, when the box body 100, the bracket 300 and the display module 400 of the spliced ​​display device are in a vertical state, the second adjustment member 220 is at least supported on the lower side of the bracket 300 in the vertical direction F5, which can prevent the bracket 300 and the display module 400 arranged on the bracket 300 from sinking relative to the base plate 110, and avoid some of the bracket 300 and the display module 400 arranged on the bracket 300 from moving downward along the vertical direction F5 relative to the base plate 110, resulting in pixel deviation and poor display effect, etc., to ensure that the spliced ​​display device maintains good splicing effect and display effect.

[0064] In some embodiments, taking a single box 100 as an example, Figure 3As shown, the width of the splicing gap P0 of the two brackets 300 on the upper side of the second direction F2 is significantly greater than the width of the splicing gap P0 on the lower side of the second direction F2, and the two brackets 300 are almost squeezed together on the lower side of the second direction F2. In the related art, if the above-mentioned splicing gap P0 problem occurs, the installer needs to manually adjust the position of the display module 400 relative to the box 100 to adjust the splicing gap P0. However, due to the gravity of the display module 400 itself, the poor matching position of the positioning column 320 of the bracket 300 and the positioning groove 130 of the box 100, etc., there is a risk of a larger splicing gap P0 appearing again in a short time.

[0065] In the box 100 of the present application, if the following occurs Figure 3 The splicing gap P0 shown is bad. Figure 3 To align the positions of the left bracket 300 and the display module 400, the first adjusting member 210 in the adjusting assembly 200 corresponding to the left bracket 300 can be adjusted to align the left bracket 300 and the display module 400; the second adjusting member 220 in the adjusting assembly 200 corresponding to the left bracket 300 can be adjusted to position the bracket 300 and the display module 400 in the second direction F2 / vertical direction F5 to ensure that the spliced ​​display device will not have the problem of partial sinking of the display module 400 after long-term use, thereby avoiding the problem of poor splicing gap P0 caused by the sinking of the partial display module 400.

[0066] If you want to Figure 3 To align the positions of the right bracket 300 and the display module 400, the first adjusting member 210 in the adjusting assembly 200 corresponding to the right bracket 300 can be adjusted to align the right bracket 300 and the display module 400; the second adjusting member 220 in the adjusting assembly 200 corresponding to the right bracket 300 is adjusted to position the bracket 300 and the display module 400 in the second direction F2 / vertical direction F5 to ensure that the spliced ​​display device will not have the problem of partial sinking of the display module 400 after long-term use, thereby avoiding the problem of poor splicing gap P0 caused by the sinking of the partial display module 400.

[0067] In some embodiments, Figures 4 to 6 As shown, the first adjusting member 210 and the second adjusting member 220 in the adjusting assembly 200 are both disposed on the positioning slot 130 .

[0068] like Figures 4 to 6As shown, the first adjusting member 210 is arranged on the positioning groove 130 along the first direction F1. The first adjusting member 210 abuts against the bracket 300 along the first direction F1, so that the bracket 300 can be pushed to move in the first direction F1, so that the setting position of the bracket 300 relative to the base plate 110 can be adjusted in the first direction F1, and the splicing gap P0 between two adjacent brackets 300 can also be adjusted in the first direction F1, and finally the splicing accuracy of the splicing display device in the first direction F1 meets the display effect requirements.

[0069] like Figures 1 to 3 As shown, the second adjusting member 220 is arranged on the positioning groove 130 along the second direction F2. The second adjusting member 220 abuts against the bracket 300 along the second direction F2, so that the bracket 300 can be pushed to move in the second direction F2, so that the setting position of the bracket 300 relative to the base plate 110 can be adjusted in the second direction F2, and the splicing gap P0 between two adjacent brackets 300 can also be adjusted in the second direction F2, so that the splicing accuracy of the splicing display device in the second direction F2 finally meets the display effect requirements.

[0070] like Figure 2 and Figure 3 As shown, when the display surface of the spliced ​​display device is perpendicular to the horizontal plane, that is, when the box body 100, the bracket 300 and the display module 400 of the spliced ​​display device are in a vertical state, the second adjustment member 220 is at least supported on the lower side of the bracket 300 in the vertical direction F5, which can prevent the bracket 300 and the display module 400 arranged on the bracket 300 from sinking relative to the base plate 110, and avoid some of the bracket 300 and the display module 400 arranged on the bracket 300 from moving downward along the vertical direction F5 relative to the base plate 110, resulting in pixel deviation and poor display effect, etc., to ensure that the spliced ​​display device maintains good splicing effect and display effect.

[0071] In some embodiments, the first adjusting member 210 and the second adjusting member 220 in the adjusting assembly 200 may also be respectively arranged on the frame assembly 120 and the positioning groove 130. For example, the first adjusting member 210 is arranged on the frame assembly 120, and the second adjusting member 220 is arranged on the positioning groove 130; for another example, the first adjusting member 210 is arranged on the positioning groove 130, and the second adjusting member 220 is arranged on the frame assembly 120; for another example, the number of the first adjusting member 210 is two, the two first adjusting members 210 are respectively arranged on the frame assembly 120 and the positioning groove 130, and the second adjusting member 220 is arranged on the frame assembly 120 or the positioning groove 130; for another example, the number of the first adjusting member 210 is two, the two first adjusting members 210 are respectively arranged on the frame assembly 120 and the positioning groove 130, and the number of the second adjusting member 220 is two, and the two second adjusting members 220 are respectively arranged on the frame assembly 120 and the positioning groove 130. The arrangement positions of the first adjusting member 210 and the second adjusting member 220 can be used to adaptively adjust the size and structure of the spliced ​​display device, which will not be described in detail herein.

[0072] In some embodiments, the adjustment components 200 may also be respectively disposed on the frame component 120 and the positioning groove 130. For example, one or more groups of adjustment components 200 may be disposed on the frame component 120, and at the same time, one or more groups of adjustment components 200 may be disposed on the positioning groove 130. In other words, the frame component 120 and the positioning groove 130 may be provided with adjustment components 200 at the same time.

[0073] That is to say, in the spliced ​​display device and the box 100 of the present application, the adjustment component 200 can be set alone on the frame component 120, the adjustment component 200 can also be set alone on the positioning groove 130, or the adjustment component 200 can be set on both the frame component 120 and the positioning groove 130. The setting position of the adjustment component 200 can be adaptively adjusted according to the actual needs of the spliced ​​display device and the box 100, and will not be repeated here.

[0074] As an optional implementation, Figures 1 to 6 As shown, the bracket 300 includes a plate body 310, a positioning column 320 and / or a positioning rib 330. The plate body 310 includes a first surface and a second surface opposite to each other. The first surface may be provided with a positioning column 320 corresponding to the positioning groove 130, and the positioning column 320 is used to abut against the first adjustment member 210 and the second adjustment member 220 provided on the positioning groove 130; and / or, the first surface may be provided with a positioning rib 330 corresponding to the frame assembly 120, and the positioning rib 330 is used to abut against the first adjustment member 210 and the second adjustment member 220 provided on the frame assembly 120; at the same time, the second surface is used to set the display module 400.

[0075] In some embodiments, Figures 4 to 6 As shown, when the bracket 300 is installed on the box body 100 , the positioning column 320 is located in the positioning groove 130 , and the first adjustment member 210 and the second adjustment member 220 disposed on the positioning groove 130 can act on the positioning column 320 . The moving direction of the first adjusting member 210 in the first direction F1 is determined according to the splicing gap P0 between adjacent brackets 300 to control the moving direction of the bracket 300 in the first direction F1, and the bracket 300 is pushed to move in the first direction F1 by the abutment between the first adjusting member 210 and the positioning column 320, thereby controlling the setting position of the bracket 300 in the first direction F1 to achieve adjustment of the splicing gap P0 of the bracket 300 in the first direction F1; the moving direction of the second adjusting member 220 in the second direction F2 is determined according to the splicing gap P0 between adjacent brackets 300 to control the moving direction of the bracket 300 in the second direction F2, and the bracket 300 is pushed to move in the second direction F2 by the abutment between the second adjusting member 220 and the positioning column 320, thereby controlling the setting position of the bracket 300 in the second direction F2 to achieve adjustment of the splicing gap P0 of the bracket 300 in the second direction F2, and at the same time achieving support for the bracket 300 in the second direction F2.

[0076] In some embodiments, Figures 1 to 3 As shown, when the bracket 300 is installed on the box 100 , the positioning rib 330 is located inside the box 100 and adjacent to the frame assembly 120 , and the first adjustment member 210 and the second adjustment member 220 provided on the frame assembly 120 can act on the positioning rib 330 . The moving direction of the first adjusting member 210 in the first direction F1 is determined according to the splicing gap P0 between adjacent brackets 300 to control the moving direction of the bracket 300 in the first direction F1. The first adjusting member 210 abuts against the frame assembly 120 to push the bracket 300 to move in the first direction F1, thereby controlling the setting position of the bracket 300 in the first direction F1 to achieve adjustment of the splicing gap P0 of the bracket 300 in the first direction F1; the moving direction of the second adjusting member 220 in the second direction F2 is determined according to the splicing gap P0 between adjacent brackets 300 to control the moving direction of the bracket 300 in the second direction F2. The second adjusting member 220 abuts against the positioning column 320 to push the bracket 300 to move in the second direction F2, thereby controlling the setting position of the bracket 300 in the second direction F2 to achieve adjustment of the splicing gap P0 of the bracket 300 in the second direction F2, and at the same time achieving support for the bracket 300 in the second direction F2.

[0077] As an optional implementation, Figure 2As shown, the frame assembly 120 includes a first frame 121, a second frame 122, a third frame 123 and a fourth frame 124 which are connected in sequence end to end, the first frame 121 and the third frame 123 are arranged on the bottom plate 110 along the first direction F1, and the second frame 122 and the fourth frame 124 are arranged on the bottom plate 110 along the second direction F2; wherein the second frame 122 and / or the fourth frame 124 are provided with a first adjusting member 210; at least one of the first frame 121 and the third frame 123 located on the lower side in the vertical direction F5 is provided with a second adjusting member 220.

[0078] In some embodiments, Figure 2 As shown, the frame assembly 120 includes a first frame 121, a second frame 122, a third frame 123 and a fourth frame 124. The first frame 121, the second frame 122, the third frame 123 and the fourth frame 124 are connected end to end in sequence and are arranged around the circumferential side of the base plate 110. The first frame 121 and the third frame 123 are arranged on the base plate 110 along the first direction F1, and the second frame 122 and the fourth frame 124 are arranged on the base plate 110 along the second direction F2.

[0079] Among them, Figure 2 As shown, the second frame 122 and / or the fourth frame 124 are provided with a first adjusting member 210. Since the first adjusting member 210 can abut against the bracket 300 along the first direction F1, the bracket 300 can be pushed to move in the first direction F1, so that the setting position of the bracket 300 relative to the bottom plate 110 can be adjusted in the first direction F1, and the splicing gap P0 between two adjacent brackets 300 can also be adjusted in the first direction F1, so that the splicing accuracy of the splicing display device in the first direction F1 finally meets the display effect requirements. At least one of the first frame 121 and the third frame 123 located at the lower side of the vertical direction F5 is provided with a second adjusting member 220, such as Figure 2As shown, when the box body 100 and the bracket 300 are in a vertical state, since in the frame assembly 120, the third frame 123 is located at the lower side of the vertical direction F5, a second adjusting member 220 is provided on at least the third frame 123. Since the second adjusting member 220 can abut against the bracket 300 along the second direction F2, the bracket 300 can be pushed to move upward in the second direction F2 / vertical direction F5. At the same time, the bracket 300 can also move downward in the second direction F2 / vertical direction F5 under the action of gravity. Through the combined action of the second adjusting member 220 and gravity, the bracket 300 can be moved in the second direction F2 / vertical direction F5. F2 / vertical direction F5 moves up and down, so that the setting position of the bracket 300 relative to the bottom plate 110 can be adjusted in the second direction F2, and the splicing gap P0 between two adjacent brackets 300 can also be adjusted in the second direction F2, so that the splicing accuracy of the splicing display device in the second direction F2 can finally meet the requirements of the display effect; at the same time, when the box body 100 and the bracket 300 are in a vertical state, the second adjusting member 220 is supported on the lower side of the bracket 300 in the vertical direction F5, which can prevent the bracket 300 and the display module 400 arranged on the bracket 300 from sinking relative to the bottom plate 110.

[0080] In some embodiments, the first adjusting member 210 may be separately arranged on the second frame 122 or the fourth frame 124, and the first adjusting member 210 may push the bracket 300 to move unidirectionally in the first direction F1. For example, when the first adjusting member 210 is separately arranged on the second frame 122, the first adjusting member 210 may push the bracket 300 to move toward the fourth frame 124 in the first direction F1, so as to adjust the setting position of the bracket 300 relative to the bottom plate 110 in the first direction F1, and adjust the splicing gap P0 between two adjacent brackets 300 in the first direction F1. For another example, when the first adjusting member 210 is separately arranged on the fourth frame 124, the first adjusting member 210 may push the bracket 300 to move toward the second frame 122 in the first direction F1, so as to adjust the setting position of the bracket 300 relative to the bottom plate 110 in the first direction F1, and adjust the splicing gap P0 between two adjacent brackets 300 in the first direction F1.

[0081] In other embodiments, Figure 2 As shown, the first adjustment member 210 can be simultaneously arranged on the second frame 122 and the fourth frame 124, the first adjustment member 210 can push the bracket 300 to move bidirectionally in the first direction F1, the first adjustment member 210 can push the bracket 300 to move toward the second frame 122 in the first direction F1, and the first adjustment member 210 can also push the bracket 300 to move toward the fourth frame 124 in the first direction F1, so as to adjust the setting position of the bracket 300 relative to the bottom plate 110 in the first direction F1, and adjust the splicing gap P0 between two adjacent brackets 300 in the first direction F1.

[0082] In some embodiments, Figure 2 As shown, the second adjustment member 220 is arranged on at least one frame located on the lower side of the vertical direction F5 between the first frame 121 and the third frame 123, so that the second adjustment member 220 can push the bracket 300 to move upward in the second direction F2 / vertical direction F5 (move toward the first frame 121) to adjust the setting position of the bracket 300 relative to the base plate 110 in the second direction F2 / vertical direction F5, and adjust the splicing gap P0 between two adjacent brackets 300 in the second direction F2 / vertical direction F5, and at the same time, the second adjustment member 220 is also supported on the lower side of the bracket 300 in the vertical direction F5.

[0083] In some other embodiments, the second adjusting member 220 can be simultaneously disposed on the first frame 121 and the third frame 123, so that the second adjusting member 220 can push the bracket 300 to move upward or downward in the second direction F2 / vertical direction F5, so as to adjust the setting position of the bracket 300 relative to the bottom plate 110 in the second direction F2 / vertical direction F5, and adjust the splicing gap P0 between two adjacent brackets 300 in the second direction F2 / vertical direction F5. It should be noted that after adjusting the setting position of the bracket 300 relative to the box body 100 by the second adjusting member 220, it is necessary to ensure that the second adjusting member 220 is at least supported on the lower side of the bracket 300 in the vertical direction F5, so as to prevent the bracket 300 and the display module 400 from sinking relative to the bottom plate 110 by the second adjusting member 220.

[0084] As an optional implementation, Figure 2 As shown, at least one first adjusting member 210 is provided on the second frame 122, and / or at least one first adjusting member 210 is provided on the fourth frame 124; at least two second adjusting members 220 are provided on one of the first frame 121 and the third frame 123 located on the lower side in the vertical direction F5.

[0085] In some embodiments, Figure 2As shown, in the first direction F1 / horizontal direction F4, since the first adjusting member 210 is used to push the bracket 300 to move relative to the base plate 110, one first adjusting member 210 can achieve this function. Therefore, in the first direction F1 / horizontal direction F4, at least one first adjusting member 210 is required, and the first adjusting member 210 can be set on the second frame 122 and / or the fourth frame 124; optionally, the first adjusting member 210 can be set in the middle position of the second frame 122 and / or the middle position of the fourth frame 124. In the second direction F2 / vertical direction F5, since the second adjusting member 220 is not only used to push the bracket 300 to move relative to the bottom plate 110, but also used to support the lower side of the bracket 300 in the vertical direction F5, in order to ensure that the second adjusting member 220 supports the bracket 300 while preventing the bracket 300 from tilting, at least two second adjusting members 220 are required to support the lower side of the bracket 300 in the vertical direction F5; optionally, at least two second adjusting members 220 are evenly distributed on both sides of the center of a frame located at the lower side of the vertical direction F5 in the first frame 121 and the third frame 123. For example, Figure 2 As shown, when the third frame 123 is located at the lower side in the vertical direction F5, the adjustment assembly 200 includes two second adjustment members 220, and the two second adjustment members 220 are relatively arranged on both sides of the center of the third frame 123, and the positions of the two second adjustment members 220 on the third frame 123 are equal to the distance from the center of the third frame 123, so that the two second adjustment members 220 can be balanced and stably supported on the lower side of the bracket 300.

[0086] In some embodiments, the first adjustment member 210 provided on the second frame 122 and the fourth frame 124 is not limited to one, and more than two first adjustment members 210 may be provided on the second frame 122 and the fourth frame 124. The number of first adjustment members 210 on the second frame 122 and the fourth frame 124 may be determined according to the size of the second frame 122 and the fourth frame 124. When the size of the second frame 122 and the fourth frame 124 is larger, more first adjustment members 210 may be provided, and when the size of the second frame 122 and the fourth frame 124 is smaller, fewer first adjustment members 210 may be provided. The second adjusting members 220 provided on one of the first frame 121 and the third frame 123 located at the lower side of the vertical direction F5 is not limited to two. More than three second adjusting members 220 may be provided on one of the first frame 121 and the third frame 123 located at the lower side of the vertical direction F5. The number of second adjusting members 220 on one of the first frame 121 and the third frame 123 located at the lower side of the vertical direction F5 may be determined according to the size of one of the first frame 121 and the third frame 123 located at the lower side of the vertical direction F5. When the size of one of the first frame 121 and the third frame 123 located at the lower side of the vertical direction F5 is larger, more second adjusting members 220 may be provided. When the size of one of the first frame 121 and the third frame 123 located at the lower side of the vertical direction F5 is smaller, fewer second adjusting members 220 may be provided.

[0087] As an optional implementation, Figure 2 As shown, the frame assembly 120 is provided with a first adjustment hole penetrating the frame assembly 120 , and the first adjustment member 210 and the second adjustment member 220 are respectively disposed in the first adjustment hole and can move relative to the first adjustment hole.

[0088] In some embodiments, a first adjustment hole that passes through the frame assembly 120 is opened on the frame assembly 120. By setting the first adjustment member 210 in the first adjustment hole and moving relative to the first adjustment hole, the first adjustment member 210 can move in the first direction F1 through the first adjustment hole to push the bracket 300 to move in the first direction F1; similarly, by setting the second adjustment member 220 in the first adjustment hole and moving relative to the first adjustment hole, the second adjustment member 220 can move in the second direction F2 through the first adjustment hole to push the bracket 300 to move in the second direction F2.

[0089] As an optional implementation, Figure 2 As shown, the first adjusting member 210 and the second adjusting member 220 are protruding relative to the inner side of the box body 100 , and the first adjusting member 210 and the second adjusting member 220 are flush or recessed relative to the outer side of the box body 100 .

[0090] In some embodiments, Figure 2 As shown, the first adjusting member 210 and the second adjusting member 220 are pre-installed in the first adjusting hole. The first adjusting member 210 and the second adjusting member 220 are made to protrude relative to the inner side of the box body 100, so as to ensure that the first adjusting member 210 and the second adjusting member 220 can abut against the bracket 300, and the first adjusting member 210 and the second adjusting member 220 are made flush or recessed relative to the outer side of the box body 100, so as to avoid the first adjusting member 210 and the second adjusting member 220 protruding relative to the outer side of the box body 100, thereby avoiding interference between the adjacent and assembled box body 100 surfaces.

[0091] As an optional implementation, Figure 2 As shown, the first adjustment hole is provided with a first internal thread, and the first adjustment member 210 and the second adjustment member 220 are provided with external threads matching the first internal thread.

[0092] In some embodiments, Figure 2 As shown, the first adjusting member 210 and the second adjusting member 220 can be screws, and the screws have external threads matching the first internal threads, so as to be threadedly connected to the first adjusting hole and move relative to the first adjusting hole through the threads. Optionally, the first adjusting member 210 and the second adjusting member 220 can be small pitch screws; optionally, the first adjusting member 210 and the second adjusting member 220 can be small pitch screws with self-locking function. The small pitch can make the first adjusting member 210 and the second adjusting member 220 have a smaller adjustment amount, and the self-locking function can make the first adjusting member 210 and the second adjusting member 220 not move randomly after adjustment, so as to ensure a good splicing gap P0 adjustment effect.

[0093] In the above-mentioned embodiment of the present application, by setting the adjustment component 200 on the frame component 120, it can be applied to the front installation and maintenance of the spliced ​​display device, so that the installation and maintenance operations of the spliced ​​display device are simple and convenient.

[0094] As an optional implementation, Figure 5 As shown, at least two positioning slots 130 provided with the adjustment components 200 on the bottom plate 110 correspond to a single bracket 300 .

[0095] In some embodiments, a plurality of positioning grooves 130 may be provided on the bottom plate 110 , and the plurality of positioning grooves 130 correspond one-to-one to the plurality of positioning posts 320 on the bracket 300 , so that the bracket 300 and the box body 100 can be aligned by placing the positioning posts 320 in the positioning grooves 130 .

[0096] In some embodiments, more than two positioning grooves 130 with adjustment components 200 can be selected on the base plate 110, and more than two positioning grooves 130 with adjustment components 200 correspond to a single bracket 300, so that at least two second adjustment members 220 correspond to the single bracket 300. When the bracket 300 is in a vertical state, it can ensure that at least two second adjustment members 220 are supported on the lower side of the vertical direction F5 of the bracket 300, thereby preventing the bracket 300 and the display module 400 arranged on the bracket 300 from sinking and tilting.

[0097] As an optional implementation, Figure 5 and Figure 6 As shown, the positioning groove 130 includes a first groove wall 131, a second groove wall 132, a third groove wall 133 and a fourth groove wall 134 which are connected in sequence end to end. The first groove wall 131 and the third groove wall 133 are arranged on the bottom plate 110 along the first direction F1, and the second groove wall 132 and the fourth groove wall 134 are arranged on the bottom plate 110 along the second direction F2; the second groove wall 132 and / or the fourth groove wall 134 are provided with a first adjusting member 210; at least one of the first groove wall 131 and the third groove wall 133 which is located on the lower side of the vertical direction F5 is provided with a second adjusting member 220.

[0098] In some embodiments, Figure 5 and Figure 6 The positioning groove 130 shown includes a first groove wall 131, a second groove wall 132, a third groove wall 133 and a fourth groove wall 134. The first groove wall 131, the second groove wall 132, the third groove wall 133 and the fourth groove wall 134 are connected end to end in sequence to form the positioning groove 130, and a space for accommodating the positioning column 320 is formed in the positioning groove 130. In the positioning groove 130, the first groove wall 131 and the third groove wall 133 are arranged on the bottom plate 110 along the first direction F1, and the second groove wall 132 and the fourth groove wall 134 are arranged on the bottom plate 110 along the second direction F2.

[0099] like Figure 5 and Figure 6As shown, the second groove wall 132 and / or the fourth groove wall 134 are provided with a first adjusting member 210, and the first adjusting member 210 can move relative to the second groove wall 132 and / or the fourth groove wall 134 in the first direction F1, so that the first adjusting member 210 abuts against the positioning column 320 accommodated in the positioning groove 130. Since the first adjusting member 210 can abut against the bracket 300 along the first direction F1, the bracket 300 can be pushed to move in the first direction F1, so that the setting position of the bracket 300 relative to the bottom plate 110 can be adjusted in the first direction F1, and the splicing gap P0 between two adjacent brackets 300 can also be adjusted in the first direction F1, so that the splicing accuracy of the splicing display device in the first direction F1 meets the display effect requirements.

[0100] like Figure 5 and Figure 6 As shown, a second adjusting member 220 is disposed on at least one of the first groove wall 131 and the third groove wall 133 that is located at the lower side in the vertical direction F5. Since the third groove wall 133 in the positioning groove 130 is located at the lower side in the vertical direction, a second adjusting member 220 is provided on at least the third groove wall 133. Since the second adjusting member 220 can abut against the bracket 300 along the second direction F2, the bracket 300 can be pushed to move upward in the second direction F2. At the same time, the bracket can move downward in the second direction F2 under the action of gravity, so that the setting position of the bracket 300 relative to the bottom plate 110 can be adjusted in the second direction F2, and the splicing gap P0 between two adjacent brackets 300 can also be adjusted in the second direction F2, so that the splicing accuracy of the splicing display device in the second direction F2 finally meets the display effect requirements; at the same time, when the box body 100 and the bracket 300 are in a vertical state, the second adjusting member 220 is supported on the lower side of the bracket 300 in the vertical direction F5, which can prevent the bracket 300 and the display module 400 arranged on the bracket 300 from sinking relative to the bottom plate 110.

[0101] As an optional implementation, Figure 5 and Figure 6 As shown, a first adjusting member 210 is respectively provided on the second groove wall 132 and / or the fourth groove wall 134 ; a second adjusting member 220 is provided on the lower side of the first groove wall 131 and the third groove wall 133 in the vertical direction F5 .

[0102] In some embodiments, Figure 5 and Figure 6As shown, a first adjusting member 210 is respectively provided on the second groove wall 132 and the fourth groove wall 134 of the positioning groove 130, and a second adjusting member 220 is provided on the third groove wall 133. When the positioning column 320 of the bracket 300 is placed in the positioning groove 130 of the box body 100 for positioning and matching, the first adjusting member 210 is adjusted to move the first adjusting member 210 in the first direction F1, so that the first adjusting member 210 can be abutted against the positioning column 320 of the bracket 300 in the first direction F1; under the action of gravity and in combination with adjusting the second adjusting member 220, the second adjusting member 220 is moved in the second direction F2, and the second adjusting member 220 is abutted against the positioning column 320 of the bracket 300 in the second direction F2; through the action of the first adjusting member, the second adjusting member and gravity, the position of the bracket 300 relative to the bottom plate 110 can be adjusted in the first direction F1 and the second direction F2, and finally the purpose of adjusting the splicing gap P0 of the bracket 300 in the first direction F1 and the second direction F2 is achieved. At the same time, it can also ensure that the second adjusting member 220 is supported on the lower side of the bracket 300 in the vertical direction F5, so as to prevent the bracket 300 and the display module 400 disposed on the bracket 300 from sinking.

[0103] In some embodiments, Figure 5 and Figure 6 As shown, the first adjusting member 210 and the second adjusting member 220 are pre-installed on the positioning groove 130. After the positioning column 320 of the bracket 300 is placed in the space in the positioning groove 130, the first adjusting member 210 can be adjusted according to actual needs. Generally, one of the first adjusting member 210 on the second groove wall 132 and the first adjusting member 210 on the fourth groove wall 134 is in use, and the other is reserved. At the same time, the second adjusting member 220 can be adjusted according to actual needs. On the one hand, the splicing gap P0 of the bracket 300 in the first direction F1 meets the splicing requirements. On the other hand, the second adjusting member 220 needs to be supported on the lower side of the positioning column 320 in the vertical direction to ensure that during the use of the spliced ​​display device, the second adjusting member 220 is always supported on the lower side of the positioning column 320 in the vertical direction to prevent the bracket 300 and the display module 400 from sinking.

[0104] In the box 100 where the adjustment component 200 is arranged on the positioning groove 130, during the assembly process of the spliced ​​display device, the bracket 300 and the display module 400 can be assembled while adjusting the installation position and the splicing gap P0 of the bracket 300 and the display module 400, and the setting position and the splicing gap P0 of the display module 400 can be adjusted in time. After the spliced ​​display device is assembled, if it is found that the splicing gap P0 effect at a certain position is not good and cannot meet the splicing gap P0 requirement, the display module 400 at the position where the splicing gap P0 needs to be adjusted can be removed from the bracket 300, and then the splicing gap P0 can be adjusted by the adjustment component 200. In the box 100 with a removable bottom plate 110, the splicing gap P0 of the adjustment component 200 can also be adjusted directly on the back of the spliced ​​display device by removing the bottom plate 110, so that the operation of adjusting the splicing gap P0 is simpler and more convenient, so as to take into account both front maintenance and rear maintenance.

[0105] As an optional implementation, Figure 5 As shown, the orthographic projection of the positioning groove 130 in which the adjustment assembly 200 is provided on the bracket 300 is located on the diagonal line of the bracket 300 .

[0106] In some embodiments, Figure 5 As shown, the projection of the positioning slot 130 on which the adjustment component 200 is provided on the bracket 300 is located on the diagonal line of the bracket 300, so that the adjustment component 200 disposed on the positioning slot 130 can be evenly distributed relative to the bracket 300, thereby avoiding the situation where the adjustment component 200 relative to the bracket 300 is concentrated on one side of the bracket 300, resulting in relatively uniform adjustment of the splicing gap P0 or prone to adjustment offset or imbalance problems.

[0107] As an optional implementation, Figures 4 to 6 As shown, the positioning groove 130 is provided with a second adjustment hole penetrating through the groove wall of the positioning groove 130 , and the first adjustment member 210 and the second adjustment member 220 are disposed in the second adjustment hole and can move relative to the second adjustment hole.

[0108] In some embodiments, Figures 4 to 6 As shown, a second adjustment hole penetrating through the wall of the positioning groove 130 is opened in the positioning groove 130, and the first adjustment member 210 is arranged in the second adjustment hole and moved relative to the second adjustment hole, so that the first adjustment member 210 can move in the first direction F1 through the second adjustment hole to push the bracket 300 to move in the first direction F1; similarly, the second adjustment member 220 is arranged in the second adjustment hole and moved relative to the second adjustment hole, so that the second adjustment member 220 can move in the second direction F2 through the second adjustment hole to push the bracket 300 to move in the second direction F2.

[0109] As an optional implementation, Figures 4 to 6As shown, the second adjustment hole is provided with a second internal thread, and the first adjustment member 210 and the second adjustment member 220 are provided with external threads matching the second internal thread.

[0110] In some embodiments, Figure 5 and Figure 6 As shown, the first adjusting member 210 and the second adjusting member 220 can be screws, and the screws have external threads matching the second internal threads, so as to be threadedly connected to the second adjusting hole and move relative to the second adjusting hole through the threads. Optionally, the first adjusting member 210 and the second adjusting member 220 can be small pitch screws; optionally, the first adjusting member 210 and the second adjusting member 220 can be small pitch screws with self-locking function. The small pitch can make the first adjusting member 210 and the second adjusting member 220 have a smaller adjustment amount, and the self-locking function can prevent the first adjusting member 210 and the second adjusting member 220 from moving randomly after adjustment, so as to ensure a good splicing gap P0 adjustment effect.

[0111] As an optional implementation, Figure 7 As shown, the adjustment assembly 200 further includes a third adjustment member 230 , which is disposed on the first side along a third direction F3 so that the third adjustment member 230 abuts against the bracket 300 along the third direction F3 , and the third direction F3 is perpendicular to the bottom plate 110 .

[0112] In some embodiments, Figure 7 As shown, the third adjustment member 230 can be moved in the third direction F3 to adjust the distance between the bracket 300 and the base plate 110 in the third direction F3, so that the bracket 300 and the display module 400 set on the bracket 300 maintain the same height relative to the base plate 110 in the third direction F3 to ensure the flatness of each display module 400 in the spliced ​​display device.

[0113] In some embodiments, Figure 7 As shown, the third adjustment member 230 can be a machine screw set on the base plate 110. The machine screw moves in the third direction F3 relative to the base plate 110, and then abuts against the bracket 300 to adjust the distance between the bracket 300 and the base plate 110, so as to achieve the purpose of adjusting the flatness of the bracket 300.

[0114] In some embodiments, each bracket 300 is correspondingly provided with at least three third adjustment members 230 that are not in the same straight line, so as to be supported between the bottom plate 110 and the bracket 300 in the third direction F3, thereby ensuring the flatness of the spliced ​​display device.

[0115] In some embodiments, Figure 7As shown, each bracket 300 is provided with four third adjustment members 230. Optionally, the orthographic projections of the four third adjustment members 230 on the bracket 300 are respectively located at the four corners of the bracket 300 to be evenly supported between the bottom plate 110 and the bracket 300. When the spliced ​​display device is assembled, if there is a step difference between adjacent display modules 400 and the flatness requirement is not met, the third adjustment members 230 at the corresponding positions can be adjusted to eliminate the step difference between adjacent display modules 400, so that the spliced ​​display device meets the flatness requirement and achieves a good flatness adjustment effect of the third adjustment member 230.

[0116] In the above-mentioned embodiment of the present application, the problem of poor splicing gap P0 of the display module 400 and easy sinking of the display module 400 can be conveniently and effectively solved by adjusting the component 200. The adjustment method of the splicing gap P0 of the box body 100 of the present application is simple, easy to implement, and convenient to operate. The splicing gap P0 adjustment effect is good, and the problem of sinking of the display module 400 in the splicing display device can be solved. It can be used in COB (Chip On Board), SMD (Surface Mounted Devices), COG (Chip On Glass), and other display module 400 splicing fields, and is compatible with the front maintenance and / or rear maintenance of the splicing display device, which can meet consumers' pursuit of a more extreme splicing effect of the splicing gap P0 of a larger-sized display device.
