[0025] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of a display module 10 of the prior art. Figure 1 As shown, the display module 10 of the prior art includes a box body 110, a board 113, a stud 11 and a screw 12. A receiving groove 111 is provided on the second surface 110b of the box body 110 (i.e., the back side of the box body 110). A plurality of studs 11 are fixed on the receiving groove 111 by adhesive. The stud 11 is provided with a threaded hole. The board 113 is provided with a first positioning hole 211. When installing the board 113, the stud 11 is aligned with the first positioning hole 211 to place the board 113 in the receiving groove 111, and the screw 12 is relatively fixed in the threaded hole to install the board 113 on the second surface 110b of the box body 110. However, when installing the display module 10 of the prior art, sufficient maintenance space needs to be reserved on the back of the display module 10 to facilitate maintenance personnel to remove the board 113 on the back of the box 110, that is, space for one person to move needs to be reserved on the back of the display module 10, or the maintenance personnel need to remove the entire display module 10 before repairing the board 113. The maintenance efficiency is low and the space limitation of the display module 10 is large, which limits the application scenarios of the display module 10 and is not conducive to the widespread application of the display module 10.

[0026] In view of this, the embodiment of the present application further proposes a display module 10, which is applied to a display device, and the display device uses LED display technology to display various information such as text, images, animations, etc. Figure 2-3 , Figure 2 is a schematic structural diagram of an embodiment of a display module 10 provided in the present application, Figure 3 FIG. 1 is a schematic diagram of the structure of another embodiment of the display module 10 provided in the present application. Figure 2-3 As shown, the display module 10 includes a housing 110 , a board 113 , a plurality of fasteners 310 and a plurality of connectors 320 .

[0027] The box 110 has a first surface 110a and a second surface 110b facing each other, and a receiving groove 111 is provided on the second surface 110b. The box 110 is a supporting frame of the display module 10, which is used to provide installation positions and support forces for various components of the display module 10, so that the display device can be set at various positions according to the application scenario. For example, the display device can be set at a wall, an outer wall of a building, etc., which is not specifically limited here. Furthermore, the first surface 110a of the box 110 is used to connect with the display screen so that the user can receive the display information of the display module 10 when facing the first surface 110a, and the second surface 110b of the box 110 is the side of the box 110 away from the first surface 110a.

[0028] The board 113 is arranged in the receiving groove 111 and is provided with a plurality of first positioning holes 211; a plurality of fasteners 310 and connectors 320 are used to detachably connect the board 113 to the box 110. Specifically, the board 113 is used to realize signal communication of the display device. In an optional embodiment, the board 113 may include a receiving card, a sending card and an information processing module. The receiving card is used to connect to the display screen, the output end of the sending card is connected to the input end of the receiving card, and the output end of the information processing module is connected to the input end of the sending card. The information processing module is used to process the display information to convert the display information into information recognizable by the receiving card, and send the information to the receiving card through the sending card, so that the receiving card controls the display screen to display the corresponding information. The information may include video information, audio information, image information, etc., to realize the display control function of the display module 10.

[0029] Among them, a plurality of second positioning holes 112 are provided at the position of the box body 110 corresponding to the accommodating groove 111, the first positioning hole 211 corresponds to the second positioning hole 112, and a plurality of connecting members 320 are sequentially passed through the first positioning hole 211 and the second positioning hole 112; the connecting member 320 is provided with a first connecting end 321 corresponding to the first surface 110a, and the connecting member 320 is provided with a second connecting end 322 corresponding to the second surface 110b, and a plurality of fasteners 310 are respectively connected to the first connecting end 321 and the second connecting end 322 so that the board 113 can be installed in the accommodating groove 111. When the fastener 310 is installed on the connector 320, the fastener 310 and the connector 320 rotate relative to the first clockwise direction and screw together, and the connection between the fastener 310 and the connector 320 is stable; when the fastener 310 is removed from the connector 320, the fastener 310 and the connector 320 rotate relative to the second clockwise direction and move away from each other, so that the fastener 310 is separated from the connector 320, and the fastening force between the board 113 and the receiving groove 111 disappears, so that the maintenance personnel can directly take the board 113 out of the receiving groove 111. In an optional embodiment, in order to facilitate the disassembly and fixation of the board 113, the fastener 310 and the first connecting end 321 or the second connecting end 322 of the connector 320 can be connected by threaded connection. According to the size and weight of the display module 10, the fastener 310 and the connector 320 can be matched by clearance fit, interference fit and transition fit.

[0030] Specifically, Figure 2 is a schematic diagram of the structure of the display module 10 when the box 110 is on the front side. Figure 3 1 is a schematic diagram of the structure of the display module 10 when the back of the housing 110 is connected. The housing 110 is provided with a plurality of mounting holes for mounting the display screen. The mounting position of the board 113 is usually set in the middle of the plurality of mounting holes. The plurality of mounting holes are arranged around the board 113 so that the board 113 can control the display of the display screen. Since the connecting member 320 is provided with a first connecting end 321 corresponding to the first surface 110a, and the connecting member 320 is provided with a second connecting end 322 corresponding to the second surface 110b, as shown in FIG. Figure 2 As shown, when facing the first surface 110a, the maintenance personnel can directly remove the fastener 310 on the first surface 110a, and move the operating end to the second surface 110b through the mounting holes around the board 113, so that the board 113 on the second surface 110b is separated from the box 110 along the first direction. Figure 3 As shown, when facing the second surface 110b, the maintenance personnel can directly remove the fastener 310 of the second surface 110b, so as to directly remove the board 113 along the first direction after the fastening force between the board 113 and the box body 110 disappears.

[0031] Therefore, in this embodiment, the display module 10 sets the connecting piece 320 into a first connecting end 321 and a second connecting end 322, the first connecting end 321 corresponds to the first surface 110a of the box body 110, and the second connecting end 322 corresponds to the second surface 110b of the box body 110, and a plurality of fasteners 310 are respectively connected to the first connecting end 321 and the second connecting end 322 of the connecting piece 320, so that maintenance personnel can disassemble the board 113 on the first surface 110a of the box body 110 (i.e., the front side of the box body 110) and the second surface 110b (i.e., the back side of the box body 110) to meet the disassembly requirements of the board 113 in different usage scenarios, thereby improving the applicability of the display module 10.

[0032] In one embodiment, see Figure 4 , Figure 4 yes Figure 3 The structural diagram of the middle connecting member 320. Figure 4 As shown, the connecting member 320 includes a connecting portion 323 and a positioning portion, the connecting portion 323 is connected to the positioning portion, and the two ends of the connecting portion 323 are provided with a first connecting end 321 and a second connecting end 322, and the positioning portion is engaged with the limiting portion 324 of the first positioning hole 211 and the second positioning hole 112 to limit the relative rotation of the connecting member 320 and the first positioning hole 211 and the second positioning hole 112.

[0033] Specifically, the connecting member 320 passes through the board 113 and the box 110. The connecting member 320 may be a columnar body. The axial dimension of the connecting member 320 is slightly larger than the sum of the thicknesses of the board 113 and the box 110. The shape of the connecting member 320 corresponds to the shape of the first positioning hole 211 and the second positioning hole 112. The connecting portion 323 is fixedly connected to the positioning portion. The two ends of the connecting portion 323 are provided with a first connecting end 321 and a second connecting end 322. The fastener 310 is connected to the first connecting end 321 and the second connecting end 322 to fix the board 113 in the receiving groove 111. The connecting member 320 is located in the first positioning hole 211 and the second positioning hole 112. The first positioning hole 211 and the second positioning hole 112 are provided with a limiting portion 324. When the maintenance personnel screw the fastener 310, the fastener 310 and the connecting portion 323 rotate relative to each other. The positioning portion is used to abut with the limiting portion 324 of the first positioning hole 211 and the second positioning hole 112 to limit the relative rotation of the connecting member 320 and the first positioning hole 211 and the second positioning hole 112 when the positioning portion interferes with the limiting portion 324. That is, the positioning portion is used to cooperate with the limiting portion 324 to constrain the rotation of the connecting member 320, thereby ensuring that the screwing process of the fastener 310 is not affected, and facilitating the maintenance personnel to disassemble and assemble the fastener 310.

[0034] In an optional embodiment, the axial dimension of the positioning portion is greater than or equal to the axial dimension of the connecting portion 323, or the axial dimension of the positioning portion is slightly greater than the axial dimension of the connecting portion 323. When the fastener 310 is tightly connected to the first connecting end 321 and the second connecting end 322 of the connecting member 320, the dimension of the positioning portion protruding from the connecting portion 323 in the axial direction may be substantially equal to the dimension of the fastener 310 protruding from the connecting member 320, so as to maintain the consistency of the board 113 on the box 110.

[0035] Furthermore, when the connecting member 320 is located in the first positioning hole 211 and the second positioning hole 112, the first connecting end 321 is flush with the first surface 110a in the axial direction, and the second connecting end 322 is flush with the side of the board 113 away from the second surface 110b in the axial direction. The axial dimension of the positioning portion is slightly larger than the axial dimension of the connecting portion 323, which makes it easy to remove the connecting member 320 from the first positioning hole 211 and the second positioning hole 112 through the protruding positioning portion after disassembling the fasteners 310 of the first connecting end 321 and the second connecting end 322.

[0036] In one embodiment, the first positioning hole 211 and the second positioning hole 112 are respectively provided with a first sub-hole (not shown) and a second sub-hole (not shown), the first sub-hole and the second sub-hole are connected, the first sub-hole is used to accommodate the connecting portion 323, and the second sub-hole is used to accommodate the positioning portion, and the radial dimension of the first sub-hole is greater than the radial dimension of the second sub-hole, so that the connecting position of the second sub-hole and the first sub-hole forms a limiting portion 324.

[0037] It can be understood that the specification size of the first sub-hole corresponds to the connecting portion 323, and the specification size of the second sub-hole corresponds to the positioning portion. In an optional embodiment, the radial dimension of the first sub-hole is slightly larger than the radial dimension of the connecting portion 323, and the radial dimension of the second sub-hole is larger than the radial dimension of the positioning portion. The shape of the first sub-hole can be the same as that of the connecting portion 323, or it can be different. For example, when the connecting portion 323 is a hexagonal cylinder, the first sub-hole can be a hexagonal hole with a slightly larger size, or the first sub-hole can be a circular hole, and the diameter of the circular hole is larger than the diameter of the circumscribed circle of the hexagon. Similarly, the shape of the second sub-hole can be the same as that of the positioning portion, or it can be different. The shapes of the first sub-hole and the second sub-hole are not specifically limited here.

[0038] Due to the size difference between the second sub-hole and the first sub-hole, when an external force is used to drive the fastener 310 to rotate relative to the connecting member 320, the connecting member 320 rotates driven by the fastener 310, and the positioning portion interferes with the connection position of the first sub-hole and the second sub-hole and limits the further rotation of the connecting member 320, preventing the fastener 310 from slipping during the screwing process, effectively improving the connection stability between the fastener 310 and the connecting member 320, and improving the stability of the display module 10.

[0039] In one embodiment, the first connection end 321 and the second connection end 322 are respectively provided with threaded holes, and the fastener 310 is threadedly connected to the threaded holes of the first connection end and the second connection end 322 to fix the board 113 to the receiving groove 111 .

[0040] Specifically, the first connection end 321 and the second connection end 322 are respectively provided with threaded holes. For example, the first connection end 321 is provided with a first threaded hole, and the second connection end 322 is provided with a second threaded hole. Both the first threaded hole and the second threaded hole are internal threads. It can be understood that the fastener 310 is provided with external threads. When the fastener 310 is connected to the connecting member 320, when the fastener 310 is screwed into the first threaded hole or the second threaded hole, the fastener 310 and the connecting member 320 are tightly connected through the meshing of the internal thread and the external thread, thereby ensuring the connection stability of the fastener 310 and the connecting member 320.

[0041] In one embodiment, the first connection end 321 is located in the first positioning hole 211, the second connection end 322 is located in the second positioning hole 112, the fastener 310 includes a first fastener 310 and a second fastener 310, the first fastener 310 is installed at the first connection end 321, and the second fastener 310 is installed at the second connection end 322. The first fastener 310 is detached from the first connection end 321 or the second fastener 310 is detached from the second connection end 322, and the board 113 is used to detach from the box 110 along the first direction under the action of an external force.

[0042] Specifically, the first fastener 310 is installed at the first connection end 321, and the second fastener 310 is installed at the second connection end 322. Figure 2 As shown, the maintenance personnel can release the fixing relationship between the board 113 and the receiving groove 111 by removing the first fastener 310 at the front of the box body 110, as shown in FIG. Figure 3 As shown, the maintenance personnel can release the fixing relationship between the board 113 and the receiving groove 111 by removing the second fastener 310 at the back of the box body 110, so that the maintenance personnel can directly remove the board 113 along the first direction.

[0043] In one embodiment, the box body 110 is provided with at least one mounting hole, which is located on one side of the accommodating groove 111. The first fastener 310 is separated from the first connecting end 321, and the mounting hole forms an operating space to apply an external force to the board 113 through the operating space. The board 113 is used to separate from the box body 110 along the first direction under the action of the external force.

[0044] Specifically, the box 110 is provided with at least one mounting hole, the mounting hole is located on one side of the receiving groove 111, and the mounting hole is used to mount the display screen, and the display screen can be fixed to the mounting hole by a magnetic buckle. When there is a large display requirement, the display screen of the display module 10 can be composed of multiple light panels, and the display device is composed of the display screens of multiple display modules 10 to expand the display area and improve the viewing effect of the user.

[0045] Before the maintenance personnel disassemble the board 113 from the front of the box 110, they first release the magnetic connection between the display screen and the mounting hole, so as to remove the display screen and expose the mounting hole from the front of the box 110. The maintenance personnel disassemble the first fastener 310 so that the first fastener 310 is separated from the first connection end 321 and the connection between the board 113 and the box 110 is released. The maintenance personnel apply an external force to the board 113 through the operating space formed by the mounting hole, so that the board 113 is separated from the box 110 along the first direction under the action of the external force, and the board 113 is taken out of the operating space to perform maintenance on the board 113. When the back space of the display module 10 is relatively limited, the maintenance personnel can directly dismantle and maintain the board 113 from the front of the box 110, thereby improving the applicability of the display module 10.

[0046] In one embodiment, the box body 110 is provided with at least one mounting hole, which is located on one side of the accommodating groove 111. The display module 10 includes a plurality of lamp panels, which are provided with a plurality of first magnetic parts. The box body 110 is provided with a plurality of second magnetic parts in the circumference of the mounting hole. The first magnetic parts and the second magnetic parts are magnetically connected to each other so that the plurality of lamp panels are connected to the box body 110.

[0047] Specifically, the display screen of the display module 10 can be composed of a plurality of lamp panels, the lamp panels are provided with a plurality of first magnetic parts, the box body 110 is provided with a plurality of second magnetic parts in the circumferential direction of the mounting hole, and the first magnetic parts are connected to the second magnetic parts by magnetism. One of the first magnetic part and the second magnetic part is a magnetic material with ferromagnetism, and the other of the first magnetic part and the second magnetic part is a metal material that can be attracted by the ferromagnetic material. In an optional embodiment, a plurality of metal parts are provided on the side of the lamp panel facing the first surface 110a, and a plurality of magnets are provided on the box body 110 at positions corresponding to the metal parts. For example, when the lamp panel is a regular quadrilateral, the metal parts can be provided at the four corners of the lamp panel, the midpoint of each side and the geometric center, or the metal parts on the lamp panel are arranged in sequence on each side of the lamp panel at the same interval to improve the connection stability of the lamp panel on the box body 110.

[0048] In one embodiment, the board 113 is provided with a third positioning hole (not shown), and the receiving slot 111 is provided with a guide member (not shown) corresponding to the third positioning hole, and the guide member cooperates with the third positioning hole to position the board 113 to a preset position of the receiving slot 111.

[0049] Specifically, the board 113 is provided with a third positioning hole, and the receiving groove 111 is fixed with a guide member corresponding to the third positioning hole. After the maintenance personnel remove the board 113 from the front of the box 110 and perform maintenance, in order to facilitate the positioning of the board 113 to the preset position of the receiving groove 111, the maintenance personnel can match the guide member with the third positioning hole to ensure the accurate alignment of the board 113 and the receiving groove 111, so as to facilitate the subsequent maintenance personnel to align the first connection end 321 with the first positioning hole 211 and install the board 113. In an optional embodiment, the guide member is a guide column structure or a guide pin, the third positioning hole is a guide hole, and the guide column and the guide hole member are clearance-matched to facilitate the movement of the guide member between the third positioning holes. In other embodiments, the guide member can be set on the side of the receiving groove 111 close to the installation hole, so that the maintenance personnel can position it through the guide member, thereby reducing the damage to the components caused by inaccurate alignment of the board 113 during the installation process.

[0050] In one embodiment, the display module 10 further includes a power supply, which is electrically connected to the board 113 , so that the board 113 processes the display signal of the display module 10 .

[0051] Specifically, in one embodiment, when the volume of the power supply is relatively small, the power supply can be set on the board 113 to reduce the space occupied by the power supply and reduce the thickness of the display module 10; in another embodiment, when the power supply demand of the display module 10 is relatively large, the power supply can be layered on the side of the board 113 facing away from the second surface 110b, and the power supply can be electrically connected to the board 113 through the interface terminal, so that the board 113 processes the display signal of the display module 10 and controls the display screen.

[0052] Furthermore, an embodiment of the present application also provides a display device, which includes at least one display module 10 as described in any of the above embodiments.

[0053] Specifically, a display device with a larger display area can be obtained by assembling multiple display modules 10 to meet scenes with different display sizes. The display device can be assembled into a display device by locking the boxes 110 of the multiple display modules 10.

[0054] Among them, when the maintenance personnel are repairing at least one display module 10 of the display device, they need to repair the board 113 of each display module 10, or repair the faulty module of the display device. At this time, the maintenance personnel can choose to repair on the front or back of the display device according to whether the back space of the display device is limited: when repairing on the front, the maintenance personnel remove at least one light panel of the display module 10, and remove the fastener 310 of the first connection end 321 to obtain the board 113 on the accommodating slot 111 through the mounting hole of the display module 10; when repairing on the back, the maintenance personnel directly release the fixed relationship between the board 113 and the accommodating slot 111 by removing the fastener 310 of the second connection end 322, and disassemble the board 113 along the first direction.

[0055] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
