As shown in Figure 1, Figure 2 and Figure 9, an embodiment of one aspect of the present invention proposes a box assembly 10, the box assembly 10 is used for a display screen, and in more detail, the box assembly 10 can be used for assembling a display module to display.

The box assembly 10 includes more than two profile units 100 , and the profile units 100 are arranged in sequence along the width direction W of the profile units 100 . For example, the profile unit 100 is a strip-shaped aluminum profile. Compared with the die-casting box, the profile has better linear accuracy in the direction of its extension, and is relatively difficult to bend and deform, which is beneficial to ensure that the box assembly 10 is in its The straightness in the extension direction is beneficial to ensure the assembly accuracy of the display module and improve the display effect.

One of the two adjacent profile units 100 is provided with a guide structure, and the guide structure cooperates with the other profile unit so that the two adjacent profile units can be joined together, and the two adjacent profile units are welded together at the joint.

The box assembly 10 provided by the present invention aligns the two profile units 100 through the guide structure during the assembly process, so that a high positional accuracy can be guaranteed between the profile units 100, and the two profile units 100 after the alignment are welded On the one hand, the integrity of the two profile units 100 connected by welding is better, which avoids the risk of mutual loosening and misalignment between the profile units 100, thereby helping to ensure the flatness of the display screen; on the other hand, adjacent The two profile units 100 are processed by fusion welding, resistance welding, etc. at the joint, so that the materials of the two adjacent profile units 100 or the materials of the two adjacent profile units 100 and the solder are mutually infiltrated and fused together. The method realizes reliable and convenient connection and assembly between the profile units 100, ensures the assembly reliability of the profile units 100, and facilitates the hiding of the seams, making the product more beautiful.

In some embodiments, splicing sides 110 are respectively formed at both ends of at least part of the profile units 100 in the width direction W, and the splicing sides 110 of adjacent profile units 100 are welded. In this way, the splicing surface between two adjacent profile units 100 avoids the front side and the back side of the profile unit 100, while ensuring reliable splicing, the front side and the back side of the profile unit 100 can have better flatness and realize beautification. The appearance of the product and the installation of the convenient display module.

Further, a splicing side 110 of the profile unit 100 is provided with a guide structure, and the guide structure of the profile unit 100 is connected to the splicing side 110 of the profile unit 100 adjacent to it, so that two adjacent profile units 100 are connected to each other in the profile unit 100. The thickness direction T of the profile unit 100 is positioned, or two adjacent profile units 100 are positioned in the length direction L of the profile unit 100, or two adjacent profile units 100 are positioned in the thickness direction T and the length direction of the profile unit 100 Both are positioned on L. Thereby ensuring the flatness of two adjacent profile units 100 in the thickness direction T of the profile unit 100, and ensuring the regularity of two adjacent profile units 100 in the length direction L of the profile unit 100, reducing the risk of splicing dislocation , so as to ensure the plane accuracy of the display screen and improve the display effect.

Further, the guide structure includes a splicing portion, and a splicing portion 110 of the profile unit 100 is provided with a splicing portion, and the splicing portion of the profile unit 100 is connected to the splicing side 110 of the adjacent profile unit 100, so that Adjacent two profile units 100 are positioned in the thickness direction T and/or length direction L of the profile units 100 . The insertion method realizes the hidden connection between two adjacent profile units 100, reduces the width of the seam, further beautifies the appearance of the product, and the insertion method also has a certain pre-fixing effect, realizing the profile unit 100 The initial fixation between them is convenient for subsequent welding operations.

In some specific embodiments, as shown in FIG. 10 , FIG. 11 , FIG. 12 and FIG. 13 , the plug-in part includes an insert 150, and a splicing side 110 of the profile unit 100 is provided with a plurality of inserts 150, and a plurality of inserts The pieces 150 are arranged at intervals along the length direction L of the profile unit 100 . A plurality of grooves 112 are formed on the other splicing side 110 of the profile unit 100, and the plurality of grooves 112 and the plurality of inserts 150 are arranged one-to-one, and the inserts 150 of the profile unit 100 are inserted into adjacent profiles The groove 112 of the unit 100 enables two adjacent profile units 100 to be positioned in the length direction L of the profile unit 100 . In this way, the position between each insert 150 and the corresponding groove 112 is opposite, and the insert 150 is inserted into the groove 112 opposite to it, so that the two ends of the profile unit 100 in the length direction L can be adjacent to it The profile units 100 are kept flush to ensure the regularity of two adjacent profile units 100 in the length direction L. The design of multiple inserts 150 further reduces the risk of misalignment of two adjacent profile units 100 in the length direction L, and the product assembly is simpler and the assembly accuracy is better.

Optionally, the insert 150 is disposed on the splicing side 110 and can be detached from the splicing side 110 . For example, the insert 150 is assembled to the splice side 110 by means of fasteners, clamping, adhesive connection, welding and the like. In this way, the insert 150 can be assembled on the profile unit 100 as an independent component, which simplifies the structure of the profile unit 100 and reduces processing difficulty and cost.

Of course, in other embodiments, it is also possible to design part of the splicing side 110 to protrude outward to form the insert 150, so that the insert 150 is directly processed and constructed from the splicing side 110, which is beneficial to ensure the position accuracy of the insert 150, The positioning accuracy of the insert 150 is improved, and the integrated design of the insert 150 and the splicing side 110 is realized, further reducing the assembly steps of the product.

In some other specific embodiments, as shown in Fig. 3 and Fig. 4, the insertion part includes a convex part 113, and one splicing side 110 of the profile unit 100 is formed with a protruding part 113 protruding outward, and the other side of the profile unit 100 The splicing side surface 110 is formed with two limiting sides 114, and the two limiting sides 114 have a distance in the thickness direction T of the profile unit 100, and the convex part 113 of the profile unit 100 extends into the two sides of the adjacent profile unit 100. Between the limiting sides 114 and limited by the two limiting sides 114 , two adjacent profile units 100 are positioned in the thickness direction T of the profile unit 100 . In this way, the convex portion 113 is stopped and spaced from both sides of the convex portion 113 by the two limiting sides 114, so that the front and rear sides of the profile unit 100 can be kept flush with the profile unit 100 adjacent to it, ensuring that the adjacent The flatness of the two profile units 100 in the thickness direction T further ensures the assembly flatness of the display module and improves the display effect.

Furthermore, the limiting edge 114 and the convex portion 113 are respectively extended along the length direction L of the profile unit 100, so that the limiting edge 114 and the convex portion 113 are respectively continuously extending along the length direction L, further improving the assembly accuracy, To a certain extent, the flatness between the profile units 100 is corrected and maintained.

Of course, the above is only a preferred embodiment of the present invention, and in other embodiments, it is also possible to design the limiting edge 114 and the convex portion 113 as a discontinuous structure along the length direction L, or design the limiting edge 114 and the convex portion 113 One of them is a structure extending continuously along the length direction L, and the other is a discontinuous structure along the length direction L, so that the flatness between the profile units 100 can also be corrected and maintained.

It is worth noting that there is no conflict between the above two specific embodiments, and in some specific embodiments, the insert 150 and the convex portion 113 are provided on the same profile unit 100 . More preferably, the limiting edge 114 and the insert 150 are located on the same splicing side 110 of the profile unit 100, and the protrusion 113 and the groove 112 are located on the other splicing side 110 of the profile unit 100, so that two adjacent profile units 100 are embedded in each other and connected to each other to form an inter-embedded structure. The two are not easy to be misplaced or loosened, and the positioning is more precise.

Further, the convex part 113 includes two convex walls 1131, the two convex walls 1131 are opposite in the thickness direction T of the profile unit 100 and have a distance therebetween, and an avoidance space 1132 is defined between the two convex walls 1131, when the two convex walls 1131 The convex wall 1131 protrudes between the two limiting sides 114 , and the insertion part is inserted into the groove 112 through the escape space 1132 . In this way, while the positioning is satisfied, the insertion part can be inserted deeper into the groove 112 by avoiding the space 1132 , and the positioning is more precise.

Optionally, as shown in FIG. 6 and FIG. 7 , the cross section of the convex wall 1131 is bent to increase the strength of the convex wall 1131 and avoid the risk of deformation and breaking of the convex wall 1131 . Moreover, the two convex walls 1131 are bent towards each other, which is beneficial to increase the contact surface between the convex walls 1131 and the limiting edge 114 and improve the positioning accuracy.

In some embodiments, the profile unit 100 is provided with a first connection structure, and the first connection structure is used to connect with the second connection structure of the display module, so that the display module is assembled on the profile unit 100, wherein the first One of the connection structure and the second connection structure is the magnetic attraction structure 170 , and the other is a metal piece that can be magnetically connected to the magnetic attraction structure 170 . Compared with the existing way that the display module and the cabinet are attracted to each other through two magnets, this embodiment uses the magnetic attraction structure 170 and the metal parts to attract each other, which ensures that the display module and the cabinet are connected to each other. While the connection between the cabinets is reliable, the suction force is appropriately reduced, reducing the risk of the display module being smashed due to a large magnetic suction force during the assembly process.

In some embodiments, as shown in FIG. 5 and FIG. 8 , each profile unit 100 includes at least two sub-profiles, and the sub-profiles are arranged side by side along the width direction W of the profile unit 100 and adjacent to it. Welded into one.

Specifically, it can be understood with reference to FIG. 1 , wherein the profile unit 100 includes a sub-profile 100a and a sub-profile 100b, the sub-profile 100a and the sub-profile 100b are welded to form an integral profile unit 100, and the two profile units 100 are spliced into a box assembly 10. In this way, the arrangement order between the sub-profiles is consistent with the arrangement order between the profile units 100, the length of the sub-profiles can be processed and cut according to the size requirements of the display screen, and there is no need for assembly work in its length direction L, reducing assembly misalignment The risk is beneficial to ensure the straightness and flatness of the box assembly 10 in the length direction L.

And the sub-profiles are arranged in sequence along the transverse direction and welded together to realize the expansion of the size of the profile unit 100 in the transverse direction, so that a larger-sized profile unit 100 can be assembled by using a plurality of relatively small-sized sub-profiles. As far as the display screen is concerned, the large-sized profile unit 100 reduces the number of profile units 100 required for assembly, which not only helps reduce the number and types of materials for on-site assembly and welding, but also helps reduce assembly steps, reduce assembly errors, and improve assembly accuracy. .

Moreover, compared with large-sized sub-profiles, relatively small-sized sub-profiles are less difficult to process and easier to guarantee machining accuracy. In this embodiment, the processing difficulty of the sub-profiles is reduced while the size of the profile unit 100 is enlarged. and processing costs, to ensure the processing accuracy of sub-profiles, so that relatively small-sized sub-profiles have better linear accuracy and plane accuracy, further reduce assembly errors, and improve assembly accuracy.

For example, the sub-profile is a metal extruded profile. For example, in more detail, the sub-profile is an aluminum extruded profile, which has the advantages of light weight, high strength, not easy to deform, and low cost. It is not easily deformed and bent, and has better straightness and flatness, thereby helping to ensure the assembly accuracy of the display module in the length direction L and reducing the risk of dislocation and unevenness of the display module in the length direction L.

In some embodiments, the profile unit 100 has a back panel 120 and a front panel 130 that are spaced apart from each other, and the joint side 110 joins the back panel 120 and the front panel 130 such that the back panel 120, the front panel 130 and the joint side 110 jointly define The accommodating space 140 that can be used for accommodating electronic control components is provided. On the one hand, the connection between the back plate 120 and the front plate 130 is realized by splicing the side surfaces 110, and the overall strength of the profile unit 100 is improved, and the deformation and bending of the profile unit 100 are reduced. On the other hand, the accommodating space 140 can also be used to assemble electronic control components such as power supply, receiving card, etc., the internal layout is more compact, and the product integration is higher.

In more detail, the profile unit 100 spliced by a plurality of sub-profiles has a larger width, and thus its accommodating space 140 is larger, and various electronic control components can be arranged more flexibly inside, especially for LED displays with small dot pitches. screen, the larger accommodating space 140 is conducive to reducing the density of the electronic control components in it, the wiring between the components is also more convenient, and it has a good heat dissipation effect.

Further, the front panel 130 of each profile unit 100 is provided with a plurality of first installation positions 131 for installing a display module, and the back panel 120 of each profile unit 100 is provided with a plurality of second installation positions for installing a power supply. A location 121 and a plurality of third installation locations 122 for installing the receiving card, wherein the number of the second installation locations 121 and the number of the third installation locations 122 are respectively smaller than the number of the first installation locations 131 . In this way, compared with the existing solution of configuring a power supply and receiving card for each display module, this embodiment optimizes the quantitative relationship between the display module, receiving card and power supply, further reduces the density of electronic control components in it, and avoids power failure. In the case that the performance will be too redundant, energy saving and material reduction can be achieved.

The present invention also provides a display screen, comprising: more than two display modules and the box assembly 10 of any one of the above-mentioned embodiments, and the display modules are assembled on the profile unit 100 .

For example, the front panel 130 of the profile unit 100 is provided with a plurality of magnetic attraction structures 170 , and the display module is magnetically connected to the magnetic attraction structures 170 to be assembled on the front panel 130 .

Furthermore, the display screen is a small dot pitch LED display screen, and its LED dot pitch is P2.5 and below, such as P2.5, P2.083, P1.923, P1.8, P1.667, P1.5, P1.25, P1.0 and other LED display products.

In more detail, for example, the display screen is a small dot pitch LED conference screen.

In terms of power supply and signal connection of the display module, the module cabinet with a small dot pitch requires more connection and coordination than a large dot pitch, and the number of corresponding terminals per unit area is too large, and the density is too high, and the profile unit 100 of this embodiment has Larger width, and thus its accommodation space 140 is larger, and various electronic control components can be arranged more flexibly inside, especially for LED display screens with small dot pitches. The density of components, better heat dissipation.
