Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED display technology, and more specifically, to an LED display module and an LED housing having the same. Background Technology
[0002] Currently, in related technologies, LED plastic modules are typically manufactured using injection molding. The mounting base is placed on the back of the module, and a copper nut is embedded in the mounting base. Screws are then used to fasten the LED plastic module to the housing through threaded engagement with the copper nut. When used outdoors, the LED plastic module may expand due to sun exposure or heat from internal electronic components. This expansion can create tensile force between the screws and the copper nut, potentially causing the mounting base outside the copper nut to crack and leading to water leakage.

[0004] To achieve the above objectives, according to one aspect of the present invention, an LED display module is provided, comprising: a lamp board; a support plate supported on the rear side of the lamp board; a mounting base disposed on the support plate and protruding rearward from the support plate, the mounting base having a mounting cavity; and a connector movably disposed within the mounting cavity.
[0005] Furthermore, the mounting base includes a base body and a cover plate. A mounting cavity is formed on the base body. The cover plate covers the opening of the mounting cavity and has a clearance hole communicating with the mounting cavity. The cover plate can stop the connector to prevent the connector from detaching from the mounting cavity.
[0006] Furthermore, the size of the mounting cavity in the preset direction is larger than the size of the connector in the preset direction, which includes the left-right direction and / or the up-down direction of the LED display module.
[0007] Furthermore, the ratio of the dimension of the connector in the preset direction to the dimension of the mounting cavity in the preset direction is greater than or equal to 9:10 and less than or equal to 95:100.
[0008] Furthermore, the base body is provided with a positioning groove that communicates with the mounting cavity, and the cover plate is placed in the positioning groove and connected to the mounting base.
[0009] Furthermore, the mounting cavity is larger in the front-to-back direction of the LED display module than the connector is in the front-to-back direction.
[0010] According to another aspect of the present invention, an LED cabinet is provided, including a cabinet and an LED display module disposed on the cabinet, wherein the LED display module is the aforementioned LED display module.
[0011] Furthermore, the LED enclosure also includes connecting fittings disposed on the enclosure, which cooperate with the connecting fittings of the LED display module to fix the LED display module on the enclosure.
[0012] Furthermore, the connector includes a connecting nut, and the connecting mating part includes a connecting screw, which passes through the housing and is threadedly engaged with the connecting nut.
[0013] Furthermore, the LED cabinet also includes a top support, and the connecting screw includes a connector. The top support is detachably mounted on the cabinet and located between the cabinet and the connector, with the connector abutting against the top support.
[0014] By applying the technical solution of this utility model, the lamp board is used to emit light, thereby realizing the basic display function of the LED display module; the support plate is supported on the rear side of the lamp board, and the support plate can provide a mounting base for the lamp board and other components of the LED display module. The support plate is used to connect with the cabinet to form an integral LED cabinet; the mounting seat is set on the support plate and protrudes rearward from the support plate. The mounting seat provides a mounting base for the connector, and the connector is used to connect and mate with the connecting fitting, thereby realizing the connection between the LED display module and the cabinet; specifically, the mounting seat has a mounting cavity; the connector is movably set in the mounting cavity. Because the connector is movable, when the LED display module is subjected to a certain external force or the support plate expands and contracts due to temperature changes, causing a certain relative displacement between the support plate and the cabinet, the connector can move, thereby causing a certain deflection or offset of the connector, so that the connector will not pull on the mounting seat, thus preventing tearing between the mounting seat and the support plate, and ensuring that the LED display module will not leak water. Therefore, the technical solution of this application can effectively solve the problem of water leakage in LED display modules in related technologies. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0030] like Figures 1 to 5 As shown, this application provides an LED display module. An embodiment of the LED display module of this application includes: a lamp board 1, a support plate 10, a mounting base 20, and a connector 30; the support plate 10 is supported on the rear side of the lamp board 1; the mounting base 20 is disposed on the support plate 10 and protrudes rearward from the support plate 10, and the mounting base 20 has a mounting cavity 21; the connector 30 is movably disposed in the mounting cavity 21.
[0031] Applying the technical solution of this embodiment, the lamp board 1 is used to emit light, thereby realizing the basic display function of the LED display module; the support plate 10 is supported on the rear side of the lamp board 1, and the support plate 10 can provide an installation base for the lamp board 1 and other components of the LED display module. The support plate 10 is used to connect with the cabinet to form an integral LED cabinet; the mounting base 20 is disposed on the support plate 10 and protrudes rearward from the support plate 10. The mounting base 20 provides an installation base for the connector 30, and the connector 30 is used to connect and mate with the connecting mating parts, thereby realizing the connection between the LED display module and the cabinet; specifically, the mounting... The mounting base 20 has a mounting cavity 21; the connector 30 is movably disposed within the mounting cavity 21. Because the connector 30 is movable, when the LED display module is subjected to a certain external force, or when the support plate 10 expands and contracts due to temperature changes, causing a certain relative displacement between the support plate 10 and the housing, the connector 30 can move, causing a certain deflection or offset. This prevents the connector 30 from pulling on the mounting base 20, thus preventing tearing between the mounting base 20 and the support plate 10, and ensuring that the LED display module does not leak water. Therefore, the technical solution of this embodiment can effectively solve the problem of water leakage in LED display modules in related technologies.
[0032] In this embodiment, the support plate 10 can be a support frame or a back cover.
[0033] like Figures 1 to 5 As shown, the mounting base 20 includes a base body 22 and a cover plate 23. A mounting cavity 21 is formed on the base body 22. The cover plate 23 covers the opening of the mounting cavity 21 and has a clearance hole 231 communicating with the mounting cavity 21. The cover plate 23 can stop the connector 30 to prevent the connector 30 from detaching from the mounting cavity 21. Specifically, the cover plate 23 can cover the opening of the mounting cavity 21, thereby stopping the connector 30 inside the mounting cavity 21, so that the connector 30 will not detach from the mounting cavity 21. The clearance hole 231 can avoid the connecting mating part 50 (mentioned later), so that the connecting mating part 50 can extend into the mounting cavity 21 through the clearance hole 231, so that the connecting mating part 50 can connect and mate with the connector 30, thereby connecting the LED display module and the cabinet 40 (mentioned later). More specifically, the connector 30 includes a connecting nut 31, and the connecting mating part 50 includes a connecting screw 51. The connecting screw 51 passes through the housing 40 and is threadedly engaged with the connecting nut 31. When the connecting screw 51 and the connecting nut 31 are tightened, the connecting nut 31 abuts against the cover plate 23 in the front-to-back direction, thereby tightening the LED display module and the housing 40. The connecting screw 51 and the connecting nut 31 have the advantages of simple structure and stable connection.
[0034] like Figures 1 to 5As shown, the dimension of the mounting cavity 21 in a preset direction is larger than the dimension of the connector 30 in the preset direction, which includes the left-right direction and / or the up-down direction of the LED display module. Specifically, the dimensions of the mounting cavity 21 in both the left-right and up-down directions are larger than the dimensions of the connector 30 in the corresponding directions. That is to say, in both the left-right and up-down directions, the connector 30 is spaced apart from the inner surface of the mounting cavity 21, so that the connector 30 can be deflected or offset in both the left-right and up-down directions, thereby achieving the effect of preventing the mounting base 20 from being torn in multiple directions.
[0035] In addition, such as Figures 1 to 5 As shown, the dimension of the mounting cavity 21 in the front-rear direction of the LED display module is larger than the dimension of the connector 30 in the front-rear direction. In this way, the connector 30 is spaced apart from the inner surface of the mounting cavity 21 in the front-rear direction, so that the connector 30 can be smoothly deflected or offset, thereby avoiding the connector 30 from getting stuck when deflecting or offsetting.
[0036] Furthermore, the ratio of the dimension of the connector 30 in the preset direction to the dimension of the mounting cavity 21 in the preset direction is greater than or equal to 9:10 and less than or equal to 95:100. Specifically, the connector 30 and mounting cavity 21 that meet the above requirements ensure, on the one hand, that the gap between the connector 30 and the mounting cavity 21 is large enough, allowing the connector 30 to deflect and shift sufficiently, thus preventing the mounting base 20 from being torn. On the other hand, it ensures that the mounting cavity 21 is not too large, thus ensuring that the overall size of the mounting base 20 is appropriate and preventing the mounting base 20 from being too large and affecting the arrangement of other structures. The ratio of the dimension of the connector 30 in the preset direction to the dimension of the mounting cavity 21 in the preset direction can be 9:10, 90.5:100, 91:100, 93:100, 93.8:100, 94.7:100, or 95:100.
[0037] like Figures 1 to 5As shown, the base body 22 is provided with a positioning groove 221 communicating with the mounting cavity 21. The cover plate 23 is disposed in the positioning groove 221 and connected to the mounting base 20. Specifically, the positioning groove 221 allows the cover plate 23 to be installed in a suitable position, thereby allowing the clearance hole 231 on the cover plate 23 to be located in a suitable position, and thus allowing the clearance hole 231 to be aligned with the connector 30, thereby allowing the connecting mating part 50 to be connected and mated with the connector 30, thereby connecting the LED display module and the cabinet 40. The mounting base 20 has a mounting position disposed on the support plate 10. The support plate 10 is made of plastic, and the mounting position is also made of plastic. That is, the mounting position can be regarded as part of the support plate 10 (module plastic bottom shell). The cover plate 23 and the base body 22 are made of metal and are welded together to form a whole. Then, the mounting position is embedded in the support plate 10 during injection molding.
[0038] This application also provides an LED enclosure, which includes an enclosure 40 and an LED display module disposed on the enclosure 40, wherein the LED display module is the aforementioned LED display module. The aforementioned LED display module can effectively solve the problem of water leakage in LED display modules in related technologies, and the LED enclosure with the aforementioned LED display module also has the aforementioned advantages.
[0039] like Figures 1 to 5 As shown, the LED enclosure also includes a connecting fitting 50 disposed on the enclosure 40. The connecting fitting 50 cooperates with the connecting fitting 30 of the LED display module to fix the LED display module on the enclosure 40. Specifically, the connecting fitting 50 is used to cooperate with the connecting fitting 30, thereby connecting the LED display module to the enclosure 40, thus fixing the LED display module on the enclosure 40 to form an integral LED enclosure.
[0040] like Figures 1 to 5 As shown, in this embodiment, the connector 30 includes a connecting nut 31, and the connecting mating part 50 includes a connecting screw 51. The connecting screw 51 passes through the housing 40 and is threadedly engaged with the connecting nut 31. When the connecting screw 51 and the connecting nut 31 are tightened, the connecting nut 31 abuts against the cover plate 23 in the front-back direction, thereby tightening the LED display module and the housing 40. The connecting screw 51 and the connecting nut 31 have the advantages of simple structure and stable connection.
[0041] like Figures 1 to 5As shown, the LED enclosure also includes a top support 60, and the connecting screw 51 includes a connector 511. The top support 60 is detachably mounted on the enclosure 40 and located between the enclosure 40 and the connector 511. The connector 511 abuts against the top support 60. Specifically, the top support 60 has a countersunk groove. When the connector 511 abuts against the top support 60, the connector 511 can be placed in the countersunk groove, thereby preventing the connector 511 from being exposed and thus preventing the connector 511 from interfering with other structures.
[0042] The LED cabinet using this embodiment has the following advantages:
[0043] 1. The connecting nut 31 (specifically, an M4 nut) has room to move within the mounting cavity 21;
[0044] 2. The connecting nut 31 can cause the connecting screw 51 to deflect or shift within the mounting cavity 21;
[0045] 3. The range of motion of the connecting nut 31 and the connecting screw 51 is greater than the deformation range of the support plate 10 (which may be made of PC plastic).
[0046] IV. The rubber-coated part of the mounting base 20 will not crack under stress.
