[0036] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of the at least one exemplary embodiment is actually only illustrative, but not as any limitation on the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative work, fall within the scope of protection of the present application.

[0037] As Figures 1 to 4 ​​As shown, the LED display device provided in the present application, the embodiment of the LED display device of the present application comprises: a frame 10; an LED module connected to the front side of the frame 10; a rear cover 20 connected to the rear side of the frame 10, the rear cover 20 comprising a rear cover main body 21, a surrounding part 22 and a baffle 70, the rear cover main body 21 having a mounting gap 211, the surrounding part 22 being arranged at the mounting gap 211 and extending towards the LED module, the baffle 70 being arranged at the side of the surrounding part 22 facing the LED module, the surrounding part 22 and the baffle 70 forming an accommodation space 23 for accommodating an external wire, the end of the external wire being provided with a first plug-in connector 30, the surrounding part 22 being provided with a avoiding gap 221; a control board assembly 40 arranged in the space surrounded by the frame 10, the rear cover 20 and the LED module, the control board assembly 40 comprising a first board card 41 mounted on the rear cover 20 and arranged at the avoiding gap 221, the first plug-in connector 30 being plug-in connected with the first board card 41 through the avoiding gap 221.

[0038] By applying the technical scheme of the embodiment, the frame 10, the LED module and the rear cover 20 jointly form an internal space, and the control board assembly 40 and other components are arranged in the internal space. The rear cover main body 21 is provided with the mounting gap 211, the surrounding part 22 is arranged at the mounting gap 211 and extends towards the LED module, and the baffle 70 is arranged at the side of the surrounding part 22 facing the LED module to shield the front side of the surrounding part 22; the space surrounded by the surrounding part 22 and the baffle 70 is the accommodation space 23, and the avoiding gap 221 is arranged on the surrounding part 22 and can be passed through by the external wire and the first plug-in connector 30. For the use scenario that the rear side of the LED display device needs to be arranged close to a wall or other mounting structure, the worker can only perform front maintenance on the LED display device, the worker removes the first board card 41, at this time the external wire can also enter the internal space through the avoiding gap 221, and the worker can detect and repair the first board card 41, the external wire and the first plug-in connector 30 in the internal space, and can also conveniently perform plug-in and pull-out operations of the first plug-in connector 30 and the first board card 41, so that the worker can easily perform front maintenance. Therefore, the technical scheme of the embodiment can effectively solve the problem that the worker is not easy to operate when performing front maintenance on the LED display device in the related art.

[0039] Since the LED display device is close to the wall on which the LED display device is installed, the space between the LED display device and the wall is small, and therefore the avoiding gap 221 is arranged on the upper side wall of the enclosing part 22, which has the advantage that, when the LED display device is installed on the wall, the avoiding gap 221 is in the horizontal plane, and the worker can easily vertically pass the first plug-in connector 30 through the avoiding gap, so that the plug-in connection operation of the first plug-in connector 30 and the first board card 41 is facilitated.

[0040] It should be noted that, in this paper, "front, rear, upper, and lower" respectively refer to: when the LED module is installed on the wall, "front" refers to the side of the LED module facing the viewer, "rear" refers to the side of the LED module close to the wall, "upper" refers to the side of the LED module away from the ground, and "lower" refers to the side of the LED module close to the ground. The above-mentioned "avoiding gap 221" is a through hole, which can communicate the accommodating space 23 with the internal space of the LED display device.

[0041] As shown in Figures 4 to 7 The control board assembly 40 further includes a connecting plate 50 arranged at the avoiding gap 221 and sealing the avoiding gap 221, the first board card 41 is provided with a second plug-in connector 51, the connecting plate 50 is connected to the first board card 41, the connecting plate 50 is provided with a through hole 52 corresponding to the second plug-in connector 51, and the first plug-in connector 30 can pass through the through hole 52 and be plug-in matched with the second plug-in connector 51. The connecting plate 50 can seal the avoiding gap 221, so that the internal space in the LED display device forms a closed space, avoiding the dust and other impurities outside the LED display device from entering the internal space, thereby avoiding the impurities from polluting the components in the internal space. The connecting plate 50 is provided with the through hole 52, the first plug-in connector 30 can pass through the through hole 52, in use, the first plug-in connector 30 is plug-in matched with the second plug-in connector 51, and then the external wire is connected with the first board card 41. When the worker performs the front maintenance on the LED display device, the worker removes the first board card 41, at this time, the connecting plate 50 is also removed with the first board card 41, and the first plug-in connector 30 and the external wire also follow the first board card 41 into the internal space, so that the front maintenance operation of the worker is facilitated.

[0042] It should be noted that in the embodiment, the connecting plate 50 is arranged on the rear side of the first board card 41, the connecting plate 50 has an "L" shape structure, a first side of the connecting plate 50 is arranged perpendicularly to and fixedly connected with the first board card 41, a second side of the connecting plate 50 is arranged parallel to and opposite to the first board card 41, and the second side of the connecting plate 50 is connected with the first board card 41 through a columnar structure and is fixed with the first board card 41 through a nut. When installed, the avoiding gap 221 is in a horizontal plane, the first board card 41 is in a vertical plane, the avoiding gap 221 is perpendicular to the first board card 41, at this time, the lower side of the connecting plate 50 is located at the avoiding gap 221 and blocks the avoiding gap 221.

[0043] As shown in Figures 1 to 2 , a positioning structure 60 is arranged between the rear cover 20 and the first board card 41, the positioning structure 60 comprises a first positioning hole 61 and a positioning column 62 arranged in the first positioning hole 61, one of the positioning column 62 and the first positioning hole 61 is arranged on the rear cover 20, the other of the positioning column 62 and the first positioning hole 61 is arranged on the first board card 41, and the positioning column 62 is arranged perpendicularly to the rear cover 20. In the embodiment, the positioning column 62 is arranged perpendicularly to the rear cover 20, and the first positioning hole 61 is arranged on the first board card 41. When the first board card 41 is installed, the positioning structure 60 enables the first board card 41 to be accurately positioned with the rear cover 20, and after the first board card 41 is positioned with the rear cover 20, a subsequent fastening operation of a worker is facilitated, for example, the worker fastens the first board card 41 to the rear cover 20 by using a fixing bolt.

[0044] As shown in Figures 1 to 4 , the baffle 70 is detachably connected to the front side of the enclosing portion 22. In the embodiment, the front side of the enclosing portion 22 also forms a gap portion. Since the positioning column 62 is arranged and has a certain length, when the first board card 41 is to be removed, the first board card 41 needs to be moved forward first, so that the first positioning hole 61 on the first board card 41 is separated from the positioning column 62, and then the first board card 41 is moved upward. The advantage of arranging the gap portion is that when the worker moves the first board card 41 forward, the external wire material and the first plug-in connector 30 also move forward and pass through the gap portion, so that the external wire material and the first plug-in connector 30 do not interfere with the front wall of the enclosing portion.

[0045] The arrangement of the baffle 70 can block the gap portion, so that the internal space of the LED display device forms a closed space, and dust and other impurities outside the LED display device are prevented from entering the internal space. The baffle 70 is detachably arranged, so that the baffle 70 can not only achieve the function of resisting impurities, but also achieve the function of exposing the gap portion, thereby ensuring the integrity of the rear cover 20.

[0046] As shown in Figures 1 to 2As shown, the baffle 70 is provided with a flange structure 71 extending forward. In the embodiment, the frame 10 comprises an outer frame 11 for surrounding an inner space of the LED display device and a reinforcing beam 12 which is integrally arranged with the outer frame 11, and other components in the inner space can be fixedly connected with the reinforcing beam 12 through fastening structures. The baffle 70 is arranged at the rear side of part of the reinforcing beam 12, and thus when the worker removes the baffle 70, the worker needs to first move the baffle 70 upward so that the baffle 70 does not interfere with part of the reinforcing beam 12, and then move the baffle 70 forward. The arrangement of the flange structure 71 makes it convenient for the worker to move the baffle 70 upward.

[0047] As shown in Figures 5 to 9 , the accommodating space 23 is arranged at the bottom of the rear cover 20, and the LED display device further comprises a connecting plate 50 arranged at the avoiding gap 221 and blocking the avoiding gap 221, the connecting plate 50 is connected to the first board 41, the connecting plate 50 is provided with a via hole 52 for the first plug-in connector 30 to pass through, and the baffle 70 protrudes upward from the connecting plate 50. Due to the limitation of the processing technology, there will be a gap between the baffle 70 and the connecting plate 50, and the baffle 70 protrudes upward from the connecting plate 50, so that the gap becomes a narrow channel in the upward and downward directions. Dust and other impurities are not easy to move upward against gravity, so that the impurities are not easy to enter the inner space through the narrow channel in the upward and downward directions, thereby reducing the possibility of impurities entering the inner space.

[0048] It should be noted that the "bottom" mentioned above refers to the position on the rear side of the rear cover 20.

[0049] As shown in Figures 5 to 7 , the rear cover 20 further comprises a support column 24 arranged on the rear cover body 21, and the support column 24 is supported at the rear side of the first board 41. The support column 24 is used to support the first board 41 so that the first board 41 has a certain distance from the rear cover body 21, and when the worker performs front maintenance on the LED display device, the worker can conveniently remove the first board 41.

[0050] As shown in Figures 1 to 2 , the positioning column 62 is arranged on the support column 24, and the outer diameter of the positioning column 62 is smaller than the outer diameter of the support column 24. In this way, it is not necessary to arrange two columnar structures to realize the support function and the positioning function respectively, so that the structure of the positioning column 62 and the support column 24 is simple, and the positioning column 62 can realize the support function and the positioning function.

[0051] As shown in Figures 1 to 2As shown, mounting holes are arranged on the support column 24, and the first board card 41 is mounted on the rear cover 20 through fasteners arranged in the first board card 41 and the mounting holes. After the first board card 41 is positioned with the rear cover 20, the staff member fastens the first board card 41 with the rear cover 20 using the fasteners, which can be fixed bolts or other structures capable of achieving fastening functions.

[0052] As shown, Figures 1 to 2 The control board assembly 40 further includes a second board card mounted on the frame 10, and the front side of the first board card 41 is provided with a fourth connector 80 for plug-in connection with a third connector on the second board card. In this embodiment, the second board card is arranged on the front side of the first board card 41, the second board card is provided with the third connector, the front side of the first board card 41 is provided with the fourth connector 80, and the third connector can be plug-in connected with the fourth connector 80 to achieve electrical connection between the first board card 41 and the second board card. In this way, the layout of the connectors on the first board card 41 is reasonable, and the space between the front side of the first board card 41 and the rear side of the second board card is fully utilized.

[0053] As shown, Figures 1 to 7 The positioning column 62 is arranged on the rear cover 20, the first positioning hole 61 is arranged on the first board card 41, the second board card is provided with a second positioning hole, and the positioning column 62 is arranged in the first positioning hole 61 and the second positioning hole. In this embodiment, the positioning column 62 has a certain length, the second board card is arranged on the front side of the first board card 41, and during installation of the control board assembly 40, the first board card 41 is first positioned with the positioning column 62, and then the second board card is positioned with the positioning column 62, which can achieve positioning of the first board card 41 and the second board card with the rear cover 20, and mutual positioning between the first board card 41 and the second board card, further ensuring accurate plug-in connection between the fourth connector 80 of the first board card 41 and the third connector of the second board card.

[0054] Specifically, the LED display device in this application can be maintained from the front or the back. The staff member unscrews the fixed bolts that fix the rear cover 20 on the frame 10, and since the first board card 41 is arranged on the rear cover 20 and other components of the control board assembly 40 are arranged in the internal space, after the rear cover 20 is removed, all components of the control board assembly 40 can be exposed, and the staff member can perform back maintenance. Alternatively, the staff member removes the LED module to expose the internal space of the LED display device and the components in the internal space, and the staff member can directly remove the components of the control board assembly 40 except the first board card 41, then moves the baffle 70 upward so that the baffle 70 does not interfere with the reinforcing beam 12, removes the baffle 70, and then removes the first board card 41 together with the external connecting wires, and the staff member can perform front maintenance.
