[0081] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0082] like Figures 1 to 28As shown, according to the first aspect of the present application, the present application provides a box frame for use in a display screen, the box frame comprising a splicing assembly 10 and a main frame 20, the main frame 20 being spliced into display screens of various different or same shapes and sizes through the splicing assembly 10, the shape of the display screen including but not limited to a conventional flat screen, a curved screen or a three-dimensional screen, which not only solves the splicing problem between multiple box frames, but also can adjust the splicing angles between the box frames through the splicing assembly 10, so that they can be spliced into curved screens or three-dimensional screens with different curvatures, thereby increasing the splicing methods of the box frame, so that it can be spliced into display screens of different shapes, improving the flexibility of the box frame assembly, and increasing the practicality of the box frame.

[0083] In an optional embodiment, the main frame 20 has a rectangular structure, which has a first frame portion 21, a second frame portion 22, a third frame portion 23 and a fourth frame portion 24. The first frame portion 21 and the second frame portion 22 are arranged on both sides of the vertical direction, and the third frame portion 23 and the fourth frame portion 24 are arranged on both sides of the horizontal direction to enclose an installation space 25 with a blank position 251. The installation space 25 is used to install a display module of the display screen. The blank position 251 can be used for the display module to pass through, which is convenient for the subsequent maintenance of the display screen or the display module, and realizes the front and rear maintenance function of the display screen, that is, the display module can be disassembled and maintained from the front and rear. It has a simple structure, is easy to operate, and has low cost.

[0084] It should be noted that the lateral direction and vertical direction of the main frame 20 are related to the placement state of the box frame, that is, when the box frame is placed in one state, the lateral direction of the main frame 20 is the horizontal direction of the box frame, and when the box frame is placed in another state, the lateral direction of the main frame 20 is the direction perpendicular to the horizontal direction of the box frame. This application does not limit this.

[0085] In an optional embodiment, the cabinet frame includes a control box 30. A central control mounting plate is connected to the main frame 20. The control box 30 is mounted on the central control mounting plate so that the display module can receive signals from the control box 30 and display images. The central control mounting plate is connected to the first frame portion 21 and the second frame portion 22 at both ends, respectively. The third frame portion 23 and the fourth frame portion 24 have rib structures extending toward the center of the central control mounting plate to strengthen the main frame 20 and the central control mounting plate.

[0086] In an optional embodiment, a first connecting structure 40 is provided on the splicing assembly 10, and at least two second connecting structures that cooperate with the first connecting structure 40 are provided on the first frame portion 21, the second frame portion 22, the third frame portion 23 and the fourth frame portion 24, so that the splicing assembly 10 can be detachably installed on at least one of the first frame portion 21, the second frame portion 22, the third frame portion 23 and the fourth frame portion 24 through the cooperation between the first connecting structure 40 and the second connecting structure, so that two adjacent main frames 20 can be spliced into one through the splicing assembly 10.

[0087] Among them, since at least two second connection structures are provided on the first frame portion 21 , the second frame portion 22 , the third frame portion 23 and the fourth frame portion 24 , the splicing assembly 10 is detachably connected to any second connection structure through the first connection structure 40 . Therefore, the box frame can select the first connecting structure 40 to be connected with the second connecting structure at different positions according to the splicing shape of the display screen, such as forming a 90° splicing between two adjacent box frames to realize the splicing of a three-dimensional screen, so that it can be displayed from multiple directions, avoiding the problem that the back of a rectangular screen and a curved screen cannot be displayed; or, by replacing the splicing component 10, etc. to adjust the angle between the two adjacent box frames, the box frames can be spliced into a curved screen more accurately and quickly to improve the installation accuracy and efficiency; or the box frames can be spliced into a flat screen, and the sides of the adjacent box frames, or the sides of the splicing component 10, and the sides of the splicing component 10 are fit together with the sides of the box frame through the splicing component 10. This not only makes installation more convenient and saves trouble, but also improves the overall strength of the box frame, better supports the box frame, and avoids deformation of the box frame.

[0088] In an optional embodiment, the splicing assembly 10 includes a first splicing portion 11 and a second splicing portion 12, and the second splicing portion 12 cooperates with the first splicing portion 11 to achieve the splicing of two adjacent box frames. The first splicing portion 11 can be detachably mounted on at least one of the first frame portion 21, the second frame portion 22, the third frame portion 23 and the fourth frame portion 24, and the second splicing portion 12 can be detachably mounted on the other of the first frame portion 21, the second frame portion 22, the third frame portion 23 and the fourth frame portion 24, and the first splicing portion 11 and the second splicing portion 12 are arranged opposite to each other, so that two adjacent box frames can be connected by the first splicing portion 11 and the second splicing portion 12 to achieve the fixation of multiple box frames, and the first splicing portion 11 and the second splicing portion 12 are connected to each other. Both splicing parts 12 are detachable from the second connecting structure, so that the shape splicing of multiple box frames can be achieved by replacing the position of the second connecting structure or replacing the first splicing part 11 and the second splicing part 12, so that multiple box frames can be spliced into flat screens, three-dimensional screens and curved screens, etc., and the adjustment angle between the display screen boxes can be increased, and curved screens with different curvatures can be spliced, thereby increasing the splicing methods of the display screens, and can be spliced into display screens of different shapes, thereby improving the flexibility of display screen assembly and increasing the practicality of the display screen.

[0089] For example, when the first splicing portion 11 is installed on the first frame portion 21, the second splicing portion 12 is installed on the second frame portion 22; or, when the first splicing portion 11 is installed on the third frame portion 23, the second splicing portion 12 is installed on the fourth frame portion 24; or, when the first splicing portion 11 is installed on the first frame portion 21 and the third frame portion 23, the second splicing portion 12 is installed on the second frame portion 22 and the fourth frame portion 24, and so on. This application is not limited to this.

[0090] In an optional embodiment, the first splicing portion 11 includes a first supporting portion 11c and a first splicing piece 50, the first connecting structure 40 includes a first connecting lock 11a for connecting to the second connecting structure, the first supporting portion 11c has a first connecting plate 111c and a first splicing plate 112c arranged at an angle, the first connecting lock 11a is arranged on the first connecting plate 111c, and the first splicing piece 50 is arranged on the first splicing plate 112c, for detachably connecting to the second splicing portion 12 of another main frame 20 when the main frame 20 is spliced.
