[0024] The embodiment of the present application provides a splicing box and a display device, which mainly realizes the splicing and fixing of the first frame and the second frame and the flushing of the first top surface and the second top surface by using a splicing and fixing structure to simultaneously connect the first top surface of the first frame and the second frame; and / or simultaneously connects the first bottom surface of the first frame and the second bottom surface of the second frame to simultaneously connect the first bottom surface of the first frame and the second frame, thereby realizing the splicing and fixing of the first frame and the second frame and the flushing of the first bottom surface and the second bottom surface. In addition, the fixing position of the two frames and the splicing position are set in different directions, so that the splicing and fixing will not interfere with each other, that is, the two frames can be spliced ​​along the length direction first, and then connected to the sides of the two frames in the width direction by using the splicing and fixing structure, so that when the first frame and the second frame are locked, there is no need to disassemble the display unit at the splicing position, and only the splicing and fixing structure needs to be locked from the sides of the first frame and the second frame in the width direction. In detail, in the prior art, the first frame and the second frame are spliced ​​along the length direction. At this time, the adjacent display units of the first frame and the second frame will cover the spliced ​​sides of the first frame and the second frame. When the first frame and the second frame are locked, the display units at the spliced ​​position need to be disassembled, and then the spliced ​​sides are locked, and then the display units are reinstalled. In the present application, the splicing process is still that the first frame and the second frame are spliced ​​along the length direction, and the display units cover the spliced ​​sides. As for the fixation of the first frame and the second frame and the flushing in the width direction, the fixation and flushing of the first frame and the second frame are achieved by utilizing a splicing fixing structure that is simultaneously connected to the top and / or bottom surfaces of the first frame and the second frame. Because the fixed position of the splicing fixing structure is not located on the splicing side where the first frame and the second frame are spliced, but on at least one side in the width direction, that is, the top surface or the bottom surface, there is no need to disassemble the display unit on the splicing side, and the first frame and the second frame can be fixed directly by the top surface and / or the bottom surface of the first frame and the second frame, which is conducive to improving the installation efficiency of the display device, and because there is no need to repeatedly disassemble and assemble the display unit, it can also avoid the damage of the display unit during repeated disassembly and assembly. In addition, because the splicing fixing structure connects the top surface and / or the bottom surface of the two frames at the same time, the two frames can be locked, and the abutting plane of the flushing piece is used to make the top surface or the bottom surface of the two frames flush in the width direction, that is, the top surfaces of the two frames are flush or the bottom surfaces of the two frames are flush, thereby avoiding the display unit from displaying the picture in a misaligned manner due to the misalignment of the frame splicing, affecting the normal display of the display device.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0046] In the description of this application, it should be understood that the words "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description". Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles disclosed in this application.

[0048] See also Figure 1 , an embodiment of the present application provides a display device 100, including:

[0049] Splicing box 120;

[0050] Multiple display units 110 are arranged on the front side of the splicing box 120 .

[0051] In this embodiment, the splicing box 120 is formed by splicing a plurality of frames. By splicing a plurality of frames together, the size of the display device 100 can be effectively increased to meet the needs of consumers for large-size display. Exemplarily, a plurality of mounting slots are provided in the splicing box 120, and the plurality of mounting slots are preferably arranged in an array to facilitate the size matching manufacturing and installation of the display unit 110. In addition, preferably, a frame is divided into a plurality of mounting slots so that a plurality of display units 110 are installed in a plurality of mounting slots, each display unit 110 and a corresponding mounting slot are arranged one by one, and a plurality of display units 110 are spliced ​​in the display plane of the display device 100 to form a display screen of the display device 100. In some embodiments, the installation of the display unit 110 can be performed by gluing, threading, and magnetic suction. Preferably, the installation between the display unit 110 and the frame adopts a magnetic suction method, which is more convenient for disassembly and assembly. For the magnetic suction method, in order to ensure that the plurality of display units 110 are coplanar, the plurality of magnetic suction columns used in this embodiment are coplanar in the front direction of the frame so that the plurality of display units 110 placed on the magnetic suction columns are coplanar. A back panel is provided on the side of the splicing box 120 away from the front to protect the components in the splicing box 120, and the back panel and the frame are fixedly connected, such as by snap-on connection, embedded connection, etc., so that the side of the back panel away from the front is flat and bolt-free, which is more beautiful.

[0052] It should be noted that the display unit 110 can be a self-luminous display unit that does not require a backlight source, such as an OLED (Organic Light-Emitting Diode) display unit, a MicroLED display unit, a MiniLED display unit, or an OLEOP (Organic Electro-Luminescent with Organic Photodiodes) display unit. Regarding the OLED display unit: an organic thin film is used as a light-emitting layer, and these organic materials emit light when current passes through. Since the pixels themselves emit light, no backlight source is required. Regarding the MiniLED display unit or the MicroLED display unit, tiny LED light sources are used as pixels, and these LEDs can emit light by themselves. The MiniLED display unit or the MicroLED display unit provides high brightness, high contrast, and a wide color gamut, allowing the construction of a scalable large display screen. Regarding the OLEOP display unit: it is a new type of self-luminous display technology that combines the advantages of OLED and organic electrochromic (OECT). The OLEOP display adjusts the luminous efficiency inside the device through an electric field, so the brightness of each pixel can be dynamically adjusted as needed. The specific structure of the display unit 110 does not belong to the main improvement point of the present application and is not limited here.

[0053] In order to facilitate the description of the specific splicing structure and principle of the splicing box 120, the following description of the subsequent embodiments is based on two spliced ​​frames as an example, that is, the splicing box 120 is not limited to two frames, and it can also be composed of three, four, etc. frames. In the subsequent embodiments, the two frames are respectively defined as the first frame 121 and the second frame 122.

[0054] In some embodiments, see Figure 2 , Figure 3 as well as Figure 5 , the splicing box 120 includes:

[0055] A first frame 121, the front of which is used to mount at least one of the display units 110, the first frame 121 is provided with a first splicing side surface 1211, and at least one first plug-in component 1212 is provided on the first splicing side surface 1211;

[0056] The second frame 122, the front side of the second frame 122 is used to install at least one of the display units 110, the second frame 122 is provided with a second splicing side 1221, the second splicing side 1221 is arranged opposite to the first splicing side 1211, and at least one second connector 1222 is provided on the second splicing side 1221, the first connector 1212 is plugged into the second connector 1222 to make the front side of the first frame 121 flush with the front side of the second frame 122.

[0057] The technical solution provided by the present application is mainly to achieve the effect of completing the side splicing of the splicing box 120 without disassembling the display unit 110 by arranging the display unit 110 on the front of the frame, and using the first plug-in piece 1212 on the side of the first frame 121 and the second plug-in piece 1222 on the side of the second frame 122 to plug and match from the side, thereby improving the installation efficiency of the splicing box 120. In detail, firstly, at least one display unit 110 is installed respectively by using the first frame 121 and the second frame 122 to achieve the effect of increasing the display size; secondly, by using the first plug-in piece 1212 on the side of the first frame 121 and the second plug-in piece 1222 on the side of the second frame 122, the sides of the first frame 121 and the second frame 122 are plugged and matched through the two plug-in pieces, thereby achieving the side splicing of the two frames. Because the entire splicing process is completed from the side, the disassembly and assembly of the display unit 110 installed on the front of the splicing box 120 will not be affected, that is, the splicing process of the splicing box 120 does not require the disassembly of the display unit 110, which simplifies the splicing process of the splicing box 120, improves the installation efficiency of the splicing box 120, and effectively avoids the situation where the display unit 110 is easily damaged due to repeated disassembly. In addition, by using the first plug-in connector 1212 and the second plug-in connector 1222 to plug and match, the front faces of the two frames are flush, and then the display units 110 arranged on the frames are flush, thereby improving the display effect of the display device 100. In detail, firstly, the first connector 1212 is arranged on the first splicing side surface 1211, and the second connector 1222 is arranged on the second splicing side surface 1221; then, the first connector 1212 is plugged and matched with the second connector 1222, so as to realize the splicing of the first frame 121 and the second frame 122 and the flushing of the front of the first frame 121 and the front of the second frame 122. By utilizing the splicing and leveling of the first connector 1212 and the second connector 1222, the flushing of the front of the first frame 121 and the second frame 122 is realized, and then the display surface composed of the multiple display units 110 arranged on the frame is ensured to be in a flat state, which is conducive to improving the display effect of the display device 100.

[0058] In addition, see Figure 4, the multiple display units 110 include at least one first display unit 111 and at least one second display unit 112, the first display unit 111 is arranged on the first frame 121 and is close to the first splicing side 1211, and the second display unit 112 is arranged on the second frame 122 and is close to the second splicing side 1221; wherein, along the direction of plug-in mating of the first connector 1212 and the second connector 1222, the side of the first display unit 111 facing the second splicing side 1221 is coplanar with the first splicing side 1211, and the side of the second display unit 112 facing the first splicing side 1211 is coplanar with the second splicing side 1221.

[0059] Exemplarily, the front of the first frame 121 includes sixteen display units 110, each display unit 110 is a square plate structure, the fronts of the sixteen display units 110 are arranged in the same plane, two adjacent display units 110 are spliced ​​through their sides, and the sixteen display units 110 on the first frame 121 are in a 4*4 array structure. There are four display units 110 in a column close to the first splicing side 1211, and the sum of the dimensions of the four display units 110 in the column along the width direction of the first frame 121 is the same or similar to the width dimension of the first frame 121. The sides of the same side of the four display units 110 in the same column are arranged in the same plane.

[0060] By making the side of the first display unit 111 located on the first frame 121 facing the second splicing side 1221 coplanar with the first splicing side 1211, and the side of the second display unit 112 located on the second frame 122 facing the first splicing side 1211 coplanar with the second splicing side, when the first frame 121 and the second frame 122 are spliced, the first splicing side 1211 will contact the second splicing side 1221, and then the side of the first display unit 111 and the side of the second display unit 112 can also be in contact, basically realizing seamless splicing, and the first connector 1212 and the second connector 1222 can be hidden by the display unit 110 inside the splicing box 120, thereby improving the quality control of the display device 100.

[0061] In addition, the technical solution provided by the present application realizes the splicing of the frame by using the side plug-in method. Compared with the method of splicing from the back or front of the splicing box 120 used in the related art, the technical solution does not need to reserve the splicing operation space on the front or back of the splicing box 120 when splicing the frame, which can effectively improve the installation environment that the splicing box 120 can adapt to. For example: when the user needs to install the display device 100 on the wall, since the related art needs to operate from the back of the splicing box 120 to complete the splicing of the frame, when the display device 100 is installed on the wall, it is necessary to reserve some space between the display device 100 and the wall to complete the splicing operation, but the distance between the display device 100 and the wall is large, which may not meet the user's requirements. Or another method is adopted, that is, before installing the wall, the frame is spliced ​​first, and then installed on the wall as a whole. This method will increase the labor intensity and installation difficulty because the size of the splicing box 120 is large and the weight is heavy. The technical solution of this embodiment can complete the splicing of the frames only by installing the frames to be spliced ​​on the wall.

[0062] It should also be noted that when the display device is in the sales stage, the display device has at least two states for delivery. The first way: split the display device into multiple frames, such as a first frame, a second frame, etc., and multiple display units, and pack them in bulk for delivery. During installation, the display unit is installed on the frame, and then the frame is spliced ​​to form a large-size display device. This method can package and protect the display units separately, and has higher safety. The second way: split the display device into multiple splicing boxes, and the display unit is installed in advance on each splicing box. During installation, you only need to splice the frames. This method can simplify the installation process for users and facilitate self-installation. You can choose the specific method according to the actual situation.

[0063] For further information, see Figures 5 to 8The first splicing side surface 1211 is provided with a first docking hole 12111, and the second splicing side surface 1221 is provided with a second docking hole 12211. The first docking hole 12111 and the second docking hole 12211 have the same structure and are arranged in alignment. Along the direction perpendicular to the front of the first frame 121, the center of the first docking hole 12111 is at a first distance from the top edge of the first splicing side surface 1211, the center of the first docking hole 12111 is at a second distance from the bottom edge of the first splicing side surface 1211, the center of the second docking hole 12211 is at a third distance from the top edge of the second splicing side surface 1221, and the center of the second docking hole 12211 is at a fourth distance from the bottom edge of the second splicing side surface 1221. The first distance is equal to the third distance, and the second distance is equal to the fourth distance. The first connector 1212 and the second connector 1222 are plugged and matched through the first docking hole 12111 and the second docking hole 12211. It should be noted that the outer contours of the first docking hole 12111 and the second docking hole 12211 are both geometric shapes. In this embodiment, the outer contours of the docking holes are preferably regular geometric shapes, such as rectangular shapes, to facilitate determination of the geometric center of the docking holes. Also, the top edge and bottom edge of the first splicing side surface 1211, and the top edge and bottom edge of the second splicing side surface 1221 are all flat planes, thereby ensuring that the first distance and the third distance are equal, and the second distance and the fourth distance are equal, and that when the first docking hole 12111 and the second docking hole 12211 are aligned, the top edge of the first splicing side surface 1211 is flush with the top edge of the second splicing side surface 1221, and the bottom edge of the first splicing side surface 1211 is flush with the bottom edge of the second splicing side surface 1221.

[0064] The present embodiment mainly realizes the splicing of two frames by utilizing the first connector 1212 and the second connector 1222 to be plugged in and matched, and by limiting the position of the first docking hole 12111 on the first splicing side surface 1211 and the position of the second docking hole 12211 on the second splicing side surface 1221, the first docking hole 12111 and the second docking hole 12211 are arranged in alignment, and when the first connector 1212 and the second connector 1222 are plugged in and matched through the first docking hole 12111 and the second docking hole 12211, the two frames are flush in the direction perpendicular to the front surface of the frames. In detail, first, a first docking hole 12111 is opened on the first splicing side surface 1211, and a second docking hole 12211 is opened on the second splicing side surface 1221, the center of the first docking hole 12111 has a first distance and a second distance from the top edge and the bottom edge of the first splicing side surface 1211 respectively, the center of the second docking hole 12211 has a third distance and a fourth distance from the top edge and the bottom edge of the second splicing side surface 1221 respectively, the first distance and the third distance are equal, and the second distance and the fourth distance are equal, so that when the first frame 121 and the second frame 122 are spliced, the first docking hole 12111 and the second docking hole 12211 can be aligned, and when the first docking hole 12111 and the second docking hole 12211 are aligned, the top edge of the first splicing side surface 1211 is flush with the top edge of the second splicing side surface 1221, and the bottom edge of the first splicing side surface 1211 is flush with the bottom edge of the second splicing side surface 1221. Then, the first connector 1212 and the second connector 1222 are spliced ​​through the first docking hole 12111 and the second docking hole 12211, and the front of the first frame 121 and the front of the second frame 122 are kept flush in a direction perpendicular to the front of the first frame 121, thereby ensuring that the multiple display units 110 arranged on the frame can remain flush, thereby improving the display effect of the display device 100.

[0065] In some embodiments, the first connector 1212 is located in the first frame 121, and at least part of the second connector 1222 is located outside the second frame 122 and extends into the first frame 121 to be plugged and matched with the first connector 1212, and the first splicing side surface 1211 and the second splicing side surface 1221 fit together. By arranging the first connector 1212 in the first frame 121, the first frame 121 and the second frame 122 can be spliced ​​as compactly as possible when splicing, avoiding the situation where the distance between the two frames is too large when splicing because the first connector 1212 is arranged outside the first frame 121. And, by making the first splicing side surface 1211 and the second splicing side surface 1221 fit together, the gap between the two frames at the splicing point can be further reduced. There are at least two examples for the fit between the first splicing side surface 1211 and the second splicing side surface 1221. In the first example, the planes of the first splicing side surface 1211 and the second splicing side surface 1221 are not flat, but when the first splicing side surface 1211 and the second splicing side surface 1221 are spliced ​​and contacted with each other, the shape of the first splicing side surface 1211 and the shape of the second splicing side surface 1221 complement each other to reduce the splicing gap between the first splicing side surface 1211 and the second splicing side surface 1221. In the second example, the planes of the first splicing side surface 1211 and the second splicing side surface 1221 are both flat, and when spliced, the first splicing side surface 1211 and the second splicing side surface 1221 are parallel and attached.

[0066] See also Fig.11 and Fig.12 In some embodiments, the first connector 1212 is a socket, the first connector 1212 is provided with a plug-in hole 12121, and the second connector 1222 is a plug connector. The second connector 1222 is plugged and matched with the plug-in hole 12121. In addition, along the direction in which the second connector 1222 is inserted into the plug-in hole 12121, the thickness of the second connector 1222 in a direction perpendicular to the front of the first frame 121 gradually decreases, so that the second connector 1222 forms a certain inclined guide surface, which is conducive to the second connector 1222 better entering the plug-in hole 12121 and playing a guiding role.

[0067] In other embodiments of the present application, the first connector 1212 may also be a plug connector, and correspondingly, the second connector 1222 is a socket, which is not limited here.

[0068] For ease of description, in subsequent embodiments, the direction perpendicular to the front face of the first frame 121 is defined as the vertical direction; the first frame 121 has a width direction and a length direction, and the connection direction of the first connector 1212 and the second connector 1222 is located in the length direction, and the width direction is perpendicular to the length direction.

[0069] In some embodiments, see Figure 3 , Figure 5 , Fig.11 as well as Fig.12 The second plug connector 1222 is disposed in the second frame 122 and extends to the outside of the second splicing side. The second plug connector 1222 is plugged into the plug-in through hole 12121, and the maximum thickness of the second plug connector 1222 in the vertical direction is equal to the maximum height of the plug-in through hole 12121 in the vertical direction. The maximum height of the plug-in through hole 12121 in the vertical direction refers to the maximum depth of the plug-in through hole 12121 in the vertical direction. If the plug-in through hole 12121 is in the shape of a circular hole, its maximum height in the vertical direction is the radial dimension of the plug-in through hole 12121. By setting the maximum thickness of the second connector 1222 in the vertical direction to be equal to the maximum height of the plug-in through hole 12121 in the vertical direction, when the second connector 1222 is inserted into the plug-in through hole 12121, the second connector 1222 and the first connector 1212 have zero degrees of freedom in the vertical direction relative to each other, effectively limiting the vertical movement of the first frame 121 and the second frame 122. In addition, since the plug-in through hole 12121 and the second connector 1222 are at the same distance from the bottom of their respective frames in the vertical direction, the plug-in through hole 12121 and the second connector 1222 have the same height in the vertical direction, and when the plug-in through hole 12121 and the second connector 1222 are plugged in, the front of the first frame 121 and the front of the second frame 122 are kept at the same height and flush (i.e., the front of the first frame 121 and the front of the second frame 122 are coplanar).

[0070] In some embodiments, the plug-in through hole 12121 has a complete inner wall, and the movement of the second plug-in connector 1222 in the vertical direction is limited by the inner wall. In other embodiments, the plug-in through hole 12121 is provided with an opening in the vertical direction and on one side facing the bottom of the first frame 121, that is, the plug-in through hole 12121 has no through hole inner wall on the side facing the bottom of the first frame 121. The first plug-in connector 1212 is arranged on the first frame 121, and the bottom structure of the first frame 121 is used as at least part of the through hole inner wall of the plug-in through hole 12121. When the second plug-in connector 1222 is inserted into the plug-in through hole 12121, the bottom structure of the first frame 121 and the inner wall of the side of the plug-in through hole 12121 facing away from the bottom structure together play a role in limiting the freedom of the second plug-in connector 1222 in the vertical direction. For the embodiment in which the plug-in through hole 12121 has an opening, the first frame 121 has a length direction, the plug-in direction of the first plug-in component 1212 and the second plug-in component 1222 is located in the length direction, and the width direction is perpendicular to the length direction. Fig. 9 and Fig.10The first plug connector 1212 includes a first fixing portion 12122, a second fixing portion 12123 and abutting portion 12124. The first fixing portion 12122 and the second fixing portion 12123 are arranged opposite to each other along the length direction and are both arranged in the first frame 121, and the abutting portion 12124 is connected to the first fixing portion 12122 and the second fixing portion 12123 on both sides of the length direction, respectively, and the connection method is an integral molding connection. Along the direction perpendicular to the front of the first frame 121 and toward the bottom surface of the first frame 121, the first fixing portion 12122 and the second fixing portion 12123 are protruded from the abutting portion 12124, so that the protruding portion of the first fixing portion 12122, the protruding portion of the second fixing portion 12123, the abutting portion 12124 and the bottom surface of the first frame 121 jointly define the plug-in through hole 12121.

[0071] Through the above-mentioned embodiments of the cooperation between the second connector 1222 and the first connector 1212, it can be known that the splicing of the first frame 121 and the second frame 122 only requires the second connector 1222 to be plugged and matched with the first connector 1212. In addition to playing the role of splicing the frames, the second connector 1222 and the first connector 1212 can also play the role of assisting the splicing of the frames to be flush in the vertical direction. Specifically, the flushing in the vertical direction only requires the second connector 1222 on the second frame 122 to be inserted into the plug-in through hole 12121 of the first connector 1212 on the first frame 121, which is simple to operate and reliable to be flush.

[0072] In some embodiments, the second plug connector 1222 is T-shaped, including a plug-in portion 12221 and a connecting portion 12222, the connecting portion 12222 is connected to the plug-in portion 12221, the plug-in portion 12221 is arranged on a side of the connecting portion 12222 close to the first plug connector 1212, illustratively, the plug-in portion 12221 is arranged close to the middle of the connecting portion 12222, the connecting portion 12222 is arranged in the second frame 122, and the plug-in portion 12221 extends from the connection with the connecting portion 12222 toward the outside of the second splicing side surface. When the first plug connector 1212 is plugged and matched with the second plug connector 1222, the plug-in portion 12221 abuts against the abutment portion 12124 and the bottom surface of the first frame 121 on both sides in a direction perpendicular to the front of the first frame 121, respectively.

[0073] Furthermore, the plug-in portion 12221 includes a head portion 122211 and a tail portion 122212, wherein the head portion 122211 is connected to the tail portion 122212, and the side of the tail portion 122212 facing away from the head portion 122211 is connected to the connecting portion 12222. Along the direction from the tail portion 122212 to the head portion 122211, the length of the head portion 122211 in the width direction gradually decreases, and the thickness in the vertical direction gradually decreases, so as to facilitate the alignment and plugging of the second plug-in component 1222 with the plug-in through hole 12121.

[0074] Furthermore, along the width direction, both sides of the head 122211 are in an arc shape, and the connection between the head 122211 and the tail 122212 is also in an arc shape and / or the head 122211 and the tail 122212 are tangentially connected. Such a configuration is conducive to the second plug-in connector 1222 smoothly entering the plug-in through hole 12121, and the head 122211 can play a guiding role in plug-in, reducing the difficulty of matching the second plug-in connector 1222 with the first plug-in connector 1212 and improving the plug-in efficiency.

[0075] Furthermore, along the width direction, both sides of the plug-in portion 12221 are clearance-fitted or spaced with both side inner walls of the plug-in through hole 12121, both side inner walls of the first docking hole 12111 and both side inner walls of the second docking hole 12211, to assist the second plug-in component 1222 in being more easily inserted into the plug-in through hole 12121.

[0076] In some embodiments, see Figure 2 The first frame 121 is provided with a first bottom surface 1213 and a first top surface 1214, and the first splicing side surface 1211 is located between the first bottom surface 1213 and the first top surface 1214 and is respectively connected to the first bottom surface 1213 and the first top surface 1214. The second frame 122 is provided with a second bottom surface 1223 and a second top surface 1224, and the second splicing side surface 1221 is located between the second bottom surface 1223 and the second top surface 1224 and is respectively connected to the second bottom surface 1223 and the second top surface 1224. In this embodiment, the first frame 121 and the second frame 122 are both rectangular, so the first bottom surface 1213 and the first top surface 1214 are both vertically connected to the first splicing side surface 1211, and the second bottom surface 1223 and the second top surface 1224 are both vertically connected to the second splicing side surface 1221. Of course, in other embodiments, the shape of the frame can also be a triangle, a pentagon, a hexagon, a circle, and other irregular shapes, etc., without limitation.

[0077] See also Fig. 9 , Fig.10 , Fig.14 , Fig.15 as well as Fig.16The splicing box body 120 further includes a splicing fixing structure 123 , and the splicing fixing structure 123 is locked to the first bottom surface 1213 and the second bottom surface 1223 .

[0078] The splicing fixing structure 123 includes a first positioning connecting member 1237, a first connecting member 1231 and a second connecting member 1232. The first positioning connecting member 1237 is arranged in the first frame 121 and extends through the first splicing side surface 1211 and the second splicing side surface 1221 to the second frame 122. The first positioning connecting member 1237 is provided with a first fixing hole 12331 and a second fixing hole 12332. The first connecting member 1231 and the second connecting member 1232 respectively pass through the first bottom surface 1213 and the second bottom surface 1223 and are respectively connected to the first fixing hole 12331 and the second fixing hole 12332. Through the arrangement of the first positioning connecting member 1237, the first connecting member 1231 and the second connecting member 1232, the first frame 121 and the second frame 122 are completely fixed in the horizontal direction, thereby improving the structural stability of the splicing box 120.

[0079] Further, the first bottom surface 1213 and the second bottom surface 1223 are respectively provided with a first threaded hole 12131 and a second threaded hole 12231. The distance between the center of the first fixing hole 12331 and the center of the second fixing hole 12332 is smaller than the distance between the center of the first threaded hole 12131 and the center of the second threaded hole 12231, and the second threaded hole 12231 and the second fixing hole 12332 are coaxially arranged, the first connecting member 1231 is threadedly connected to the first threaded hole 12131 and extends into the first fixing hole 12331, and the second connecting member 1232 is threadedly connected to the second threaded hole 12231 and extends into the second fixing hole 12332. When the first frame 121 and the second frame 122 are spliced, the first positioning connecting piece 1237 is inserted into the first frame 121, and the second connecting piece 1232 is threadedly connected to the second threaded hole 12231 and the second fixing hole 12332, and the first connecting piece 1231 is threadedly connected to the first threaded hole 12131 and extends into the first fixing hole 12331. Because the first threaded hole 12131 and the first fixing hole 12331 are eccentrically arranged, that is, they are not coaxially arranged, so that during the process of tightening the first connecting piece 1231, the part of the first connecting piece 1231 extending to the first fixing hole 12331 will form an abutment with the inner wall of the first fixing hole 12331. As the thread feed amount of the first connecting piece 1231 increases, the abutment force between the first connecting piece 1231 and the first fixing hole 12331 will also increase, thereby driving the two frames to move closer to each other and completing the locking.

[0080] Furthermore, the first positioning connector 1237 is parallel to both the first bottom surface 1213 and the second bottom surface 1223 , and can preliminarily achieve the flushness of the first bottom surface 1213 and the second bottom surface 1223 in the horizontal direction.

[0081] In this embodiment, the first positioning connector 1237 adopts a pin shaft, which effectively ensures that the axial direction of the first positioning connector 1237 is straight.

[0082] In this embodiment, the splicing box 120 further includes a flush member 124, which is provided with a first connection hole 1241 and a second connection hole 1242 and has an abutting plane 1243. The first connection member 1231 sequentially passes through the first connection hole 1241 and the first bottom surface 1213 and is fixedly connected to the first fixing hole 12331. The second connection member 1232 sequentially passes through the second connection hole 1242 and the second bottom surface 1223 and is fixedly connected to the second fixing hole 12332. The abutting plane 1243 is parallel to and abuts against the first bottom surface 1213 and the second bottom surface 1223. The abutting plane 1243 is locked to the first bottom surface 1213 and the second bottom surface 1223 by the first connection member 1231, so that the first bottom surface 1213 and the second bottom surface 1223 are both subjected to the force of the abutting plane 1243. Since the abutment plane 1243 of the flush member 124 is parallel to and abuts against the first bottom surface 1213 and the second bottom surface 1223, the first bottom surface 1213 and the second bottom surface 1223 have a tendency to move toward each other and become flush, until the abutment plane 1243 is locked to the first bottom surface 1213 and the second bottom surface 1223, and the first bottom surface 1213 and the second bottom surface 1223 are completely flush in the horizontal direction.

[0083] Furthermore, the magnitude of the force of the abutment between the abutment plane 1243 and the first bottom surface 1213 is positively correlated with the feed amount of the first connecting member 1231 toward the abutment plane 1243, and the magnitude of the force of the abutment between the abutment plane 1243 and the second bottom surface 1223 is positively correlated with the feed amount of the second connecting member 1232 toward the abutment plane 1243. When the first connecting member 1231 and the second connecting member 1232 are fed and moved toward the first bottom surface 1213 and the second bottom surface 1223 respectively, the flush member 124 will also move toward the first bottom surface 1213 and the second bottom surface 1223. The greater the feeding amount, the closer the flush member 124 is to the first bottom surface 1213 and the second bottom surface 1223, until the flush member 124 contacts the first bottom surface 1213 and the second bottom surface 1223. The greater the feeding amount of the first connecting member 1231 and the second connecting member 1232, the greater the abutment force between the flush member 124 and the first bottom surface 1213 and the second bottom surface 1223, so that the flush member 124 fits the first bottom surface 1213 and the second bottom surface 1223 more closely, thereby achieving the flushing of the first bottom surface 1213 and the second bottom surface 1223.

[0084] In another embodiment, see Fig.10 , Fig.13 , Fig.15 as well as Fig.16 The splicing box body 120 further includes a splicing fixing structure 123, and the splicing fixing structure 123 is locked to the first top surface 1214 and the second top surface 1224 so that the first top surface 1214 and the second top surface 1224 are flush.

[0085] The splicing fixing structure 123 includes a first positioning connector 1233, a first connector 1231 and a second connector 1232. The first positioning connector 1233 is arranged in the first frame 121 and extends through the first splicing side surface 1211 and the second splicing side surface 1221 to the second frame 122. The first positioning connector 1233 is provided with a first fixing hole 12331 and a second fixing hole 12332. The first connector 1231 and the second connector 1232 pass through the first top surface 1214 and the second top surface 1224 respectively and are connected to the first fixing hole 12331 and the second fixing hole 12332 respectively. By providing the first positioning connector 1233, the first connector 1231 and the second connector 1232, the first frame 121 and the second frame 122 are completely fixed in the horizontal direction, thereby improving the structural stability of the splicing box 120.

[0086] Further, the first top surface 1214 and the second top surface 1224 are respectively provided with a first threaded hole 12131 and a second threaded hole 12231. The distance between the center of the first fixing hole 12331 and the center of the second fixing hole 12332 is smaller than the distance between the center of the first threaded hole 12131 and the center of the second threaded hole 12231, and the second threaded hole 12231 and the second fixing hole 12332 are coaxially arranged, the first connecting member 1231 is threadedly connected to the first threaded hole 12131 and extends into the first fixing hole 12331, and the second connecting member 1232 is threadedly connected to the second threaded hole 12231 and extends into the second fixing hole 12332. When the first frame 121 and the second frame 122 are spliced, the positioning connecting piece 1233 is inserted into the first frame 121, and the second connecting piece 1232 is threadedly connected to the second threaded hole 12231 and the second fixing hole 12332, and the first connecting piece 1231 is threadedly connected to the first threaded hole 12131 and extends into the first fixing hole 12331. Because the first threaded hole 12131 and the first fixing hole 12331 are eccentrically arranged, that is, they are not coaxially arranged, so that during the process of tightening the first connecting piece 1231, the part of the first connecting piece 1231 extending to the first fixing hole 12331 will form an abutment with the inner wall of the first fixing hole 12331. As the thread feed amount of the first connecting piece 1231 increases, the abutment force between the first connecting piece 1231 and the first fixing hole 12331 will also increase, thereby driving the two frames to move closer to each other and completing the locking.

[0087] It should be noted that, in addition to being arranged in the first frame 121, the positioning connector 1233 can also be arranged on the outside of the second splicing side surface 1221 of the second frame 122, and the fixing method can be one-piece molding or welding connection, etc., without limitation. And the positioning connector 1233 only has a first fixing hole. When the first frame 121 and the second frame 122 are spliced, the positioning connector 1233 is inserted into the first frame, and the first connector 1231 is threadedly connected with the first threaded hole 12131 and extends into the first fixing hole 12331, and abuts against the inner wall of the first fixing hole 12331.

[0088] Furthermore, the first positioning connector 1233 is parallel to both the first top surface 1214 and the second top surface 1224 , and can preliminarily achieve the flushness of the first top surface 1214 and the second top surface 1224 in the horizontal direction.

[0089] In this embodiment, the first positioning connector 1233 adopts a pin shaft, which effectively ensures that the axial direction of the first positioning connector 1233 is straight.

[0090] In this embodiment, the splicing box 120 further includes a flushing member 124, which is provided with a first connection hole 1241 and a second connection hole 1242 and has an abutting plane 1243. When the first frame 121 and the second frame 122 are spliced, the first connecting member 1231 sequentially passes through the first connecting hole 1241 and the first top surface 1214 and is fixedly connected to the first fixing hole 12331, the second connecting member 1232 sequentially passes through the second connecting hole 1242 and the second top surface 1224 and is fixedly connected to the second fixing hole 12332, and the abutting plane 1243 is parallel to and abuts against the first top surface 1214 and the second top surface 1224. The abutting plane 1243 is locked to the first top surface 1214 and the second top surface 1224 by the first connecting member 1231 and the second connecting member 1232, so that the first top surface 1214 and the second top surface 1224 are both subjected to the force of the abutting plane 1243. Since the abutment plane 1243 of the flushing member 124 is parallel to and abuts against the first top surface 1214 and the second top surface 1224, the first top surface 1214 and the second top surface 1224 have a tendency to move toward and become flush with each other until the abutment plane 1243 is locked to the first top surface 1214 and the second top surface 1224, and the first top surface 1214 and the second top surface 1224 are flush in the horizontal direction.

[0091] Furthermore, the magnitude of the force between the abutment plane 1243 and the first top surface 1214 is positively correlated with the feed amount of the first connecting member 1231 toward the abutment plane 1243, and the magnitude of the force between the abutment plane 1243 and the second top surface 1224 is positively correlated with the feed amount of the second connecting member 1232 toward the abutment plane 1243. When the first connecting member 1231 and the second connecting member 1232 are fed and moved toward the first top surface 1214 and the second top surface 1224 respectively, the flush member 124 will also move toward the first top surface 1214 and the second top surface 1224. The greater the feeding amount, the closer the flush member 124 is to the first top surface 1214 and the second top surface 1224, until the flush member 124 contacts the first top surface 1214 and the second top surface 1224. The greater the feeding amount of the first connecting member 1231 and the second connecting member 1232, the greater the abutment force between the flush member 124 and the first top surface 1214 and the second top surface 1224, so that the flush member 124 fits the first top surface 1214 and the second top surface 1224 more closely, thereby achieving the flushing of the first top surface 1214 and the second top surface 1224.

[0092] In another embodiment, the above two embodiments are combined, that is, the splicing fixing structure 123 is locked to both the top surface and the bottom surface. Figure 2The splicing fixing structure 123 includes a first positioning connector 1233, a second positioning connector 1237, a first connector 1231, a second connector 1232, a third connector 1235 and a fourth connector 1236. The first positioning connector 1233 and the second positioning connector 1237 are both arranged in the first frame 121 and extend to the outside of the first frame 121 along the length direction. The first positioning connector 1233 and the second positioning connector 1237 are arranged opposite to each other along the width direction. When the first frame 121 When spliced ​​with the second frame 122, the first positioning connector 1233 and the second positioning connector 1237 are both inserted into the second frame 122, the first connector 1231 and the second connector 1232 pass through the first top surface 1214 and the second top surface 1224 respectively and are both connected to the first positioning connector 1233, and the third connector 1235 and the fourth connector 1236 pass through the first bottom surface 1213 and the second bottom surface 1223 respectively and are both connected to the second positioning connector 1237. By providing connectors and positioning connectors for locking on both the top and bottom surfaces of the frame, the locking effect of this embodiment is better than the previous locking solution in which connectors and positioning connectors are only provided on the top or bottom surface.

[0093] It should be noted that the flushing piece 124 is only provided on the first top surface 1214 and the second top surface 1224 or the first bottom surface 1213 and the second bottom surface 1223, preferably on the first bottom surface 1213 and the second bottom surface 1223, to avoid providing the flushing piece 124 on both the top surface and the bottom surface, as the two top surfaces and the two bottom surfaces may not be leveled due to factors such as the manufacturing accuracy of the box.

[0094] It should also be noted that, from the above embodiments of the splicing and fixing structure 123, it can be known that the splicing and fixing structure 123 can be provided only on one side of the first top surface 1214 and the second top surface 1224, or only on one side of the first bottom surface 1213 and the second bottom surface 1223, or the splicing and fixing structure 123 is provided on both the top surface and the bottom surface. Preferably, the splicing and fixing structure 123 is provided on the first bottom surface 1213 and the second bottom surface 1223, which is conducive to reducing the thickness of the first top surface 1214 and the second top surface 1224 and realizing a narrow frame of the top surface; it can also be preferably provided on both sides of the top surface and the bottom surface of the splicing and fixing structure 123, which is conducive to improving the firmness and stability of the frame splicing.

[0095] In some embodiments, see Fig.10 and Fig.16The structure of the first connecting member 1231 includes a threaded section 12311 and an abutting section 12312. The threaded section 12311 is connected to the abutting section 12312. When the first connecting member 1231 cooperates with the positioning connecting member 1233, the threaded section 12311 is threadedly connected to the first threaded hole 12131, and the abutting section 12312 extends into the first fixing hole 12331 and forms an abutment. The abutting section 12312 is in a conical shape, and along the direction from the abutting section 12312 to the threaded section 12311, the diameter of the abutting section 12312 gradually increases, so that the abutting section 12312 forms a guiding conical inclined surface, which is conducive to the abutting section 12312 being inserted into the first fixing hole 12331 and pulling the two frames closer to each other. Exemplarily, when the first frame 121 is plugged and matched with the second frame 122, during the process of tightening the first connecting member 1231, the force exerted by the first connecting member 1231 on the positioning connecting member 1233 will cause the first splicing side 1211 and the second splicing side 1221 to move toward each other, thereby achieving the locking of the first frame 121 and the second frame 122.

[0096] Furthermore, the projection of the first fixing hole 12331 along the width direction is elliptical, which is beneficial for the first connecting member 1231 to squeeze the side wall of the first fixing hole 12331 during the threaded connection process, thereby driving the first frame 121 and the second frame 122 connected by the first positioning connecting member 1233 to move closer to each other and lock.

[0097] In some embodiments, the first positioning connector 1233 is provided with a first recessed groove 12333 and a second recessed groove 12334. The first recessed groove 12333 is connected to the first fixing hole 12331, and when projected along the axial direction of the first fixing hole 12331, the projection contour of the first fixing hole 12331 is located within the projection contour of the first recessed groove 12333. The second recessed groove 12334 is connected to the second fixing hole 12332, and when projected along the axial direction of the second fixing hole 12332, the projection contour of the second fixing hole 12332 is located within the projection contour of the second recessed groove 12334. When the first frame 121 and the second frame 122 are spliced ​​and locked, the part of the first connecting member 1231 located outside the first fixing hole 12331 abuts against the bottom wall of the first groove 12333, and the part of the second connecting member 1232 located outside the second fixing hole 12332 abuts against the bottom wall of the second groove 12334, thereby preventing the first connecting member 1231 and the second connecting member 1232 from threading when they are threadedly connected to the first fixing hole 12331 and the second fixing hole 12332 respectively.

[0098] In some embodiments, see Fig.15 and Fig.16The side of the flush member 124 away from the abutting plane 1243 is provided with a first receiving groove and a second receiving groove, the first receiving groove is communicated with the first connecting hole 1241, the second receiving groove is communicated with the second connecting hole 1242, the side of the first connecting member 1231 away from the abutting plane 1243 is located in the first receiving groove, and the side of the second connecting member 1232 away from the abutting plane 1243 is located in the second receiving groove. By providing the receiving grooves, it is helpful to hide the parts of the first connecting member 1231 and the second connecting member 1232 exposed on the outside of the top surface and / or the bottom surface respectively, reduce the damage of the first connecting member 1231 and the second connecting member 1232, especially the impact of external bumps, and effectively prevent the first connecting member 1231 and the second connecting member 1232 from loosening due to external influences. In addition, the first connecting member 1231 and the second connecting member 1232 are both arranged in the accommodating groove, which, to a certain extent, provides a position for the splicing of the frame in the horizontal width direction and reduces the influence on the splicing in this direction.

[0099] Furthermore, the first receiving groove and the second receiving groove have the same structure, so only the structure of the first receiving groove is described in this embodiment. The first receiving groove is in a frustum shape, and the diameter of the first receiving groove gradually decreases along the feeding direction of the connecting member, so that the contact surface between the connecting member and the receiving groove is reduced, which is beneficial to reduce the friction of the connecting member in the receiving groove and facilitate the feeding operation of the connecting member.

[0100] For further information, see Fig.17 The first connecting hole 1241 and the second connecting hole 1242 are both waist-shaped holes, which are beneficial to reducing the matching accuracy between the connecting piece, the connecting hole, the threaded hole and the fixing hole, and reserving a part of the margin for the adjustable position of the connection of the connecting piece.

[0101] In summary, the technical solution of the present application realizes the splicing of the two frames and the flushing in the vertical direction by using the first connector 1212 and the second connector 1222, and realizes the splicing stability of the two frames and the flushing in the horizontal direction by the splicing fixing structure 123, which can not only improve the installation efficiency of the box body and avoid damage to the display unit 110 during the disassembly and assembly process, but also make the spliced ​​frames flush in the horizontal and vertical directions, and then make the screen of the display device 100 in a flat state to ensure a good display effect. In detail, it is mainly through the use of the first connector 1212 and the second connector 1222 to ensure that the spliced ​​frames are flush in the vertical direction and preliminarily realize the splicing and fixing between the frames; the splicing fixing structure 123 is used to make the spliced ​​frames flush in the horizontal direction and further improve the splicing firmness between the frames. The first plug-in connector 1212 is arranged in the first frame 121, and the second plug-in connector 1222 is arranged in the second frame 122 and plugged with the first plug-in connector 1212, so as to realize the splicing of the first frame 121 and the second frame 122 and the flushing in the vertical direction. The splicing fixing structure 123 is locked on the top surface and / or the side surface, and the abutting plane 1243 of the flushing member 124 is parallel to the top surface or the bottom surface, and the abutting plane 1243 abuts against the top surface or the bottom surface. Because the abutting plane 1243 is parallel to both bottom surfaces or both top surfaces and is in abutting state with both bottom surfaces or top surfaces, the abutting plane 1243 will act on the pressure of both top surfaces or bottom surfaces at the same time, so that the two top surfaces or the two bottom surfaces will have the ability to move toward each other, so that the two top surfaces are in a flush state in the horizontal direction toward the abutting plane 1243 or the two bottom surfaces are in a flush state in the horizontal direction toward the abutting plane 1243.
