As shown in fig. 1 to 6, the present application provides an LED module, and an embodiment of the LED module of the present application includes a support structure 10 and an LED lamp panel 20 disposed on a front side of the support structure 10, and the LED lamp panel 20 is connected to an LED box 30 through the support structure 10, wherein the support structure 10 includes: a support frame 11; a plurality of receiving holes 12 provided on the support frame 11 and penetrating the support frame 11 in the front-rear direction; a plurality of grounding pieces 13 disposed in the plurality of accommodation holes 12 in one-to-one correspondence, each grounding piece 13 being located at a rear end of the accommodation hole 12, the grounding piece 13 being movably disposed in the accommodation hole 12 and having an extended position penetrating the accommodation hole 12 and a retracted position abutting the LED housing 30 and retracted relative to the extended position; the plurality of elastic conducting pieces 14 are arranged in the plurality of accommodating holes 12 in a one-to-one correspondence manner, each elastic conducting piece 14 is located at the front end of the accommodating hole 12, the front end of each elastic conducting piece 14 is in abutting fit with the LED lamp panel 20, and the rear end of each elastic conducting piece 14 abuts against the grounding piece 13, so that the grounding piece 13 is kept at the extending position.

By applying the technical scheme of the embodiment, the LED lamp panel 20 is disposed at the front side of the supporting structure 10, the supporting structure 10 comprises a supporting frame 11, a plurality of accommodating holes 12 penetrating through the front surface and the rear surface of the supporting frame 11 are formed in the supporting frame 11, a grounding piece 13 and an elastic conducting piece 14 are arranged in each accommodating hole 12, the grounding piece 13 is located at the rear end of the accommodating hole 12, the elastic conducting piece 14 is located at the front end of the accommodating hole 12, and the front end of the grounding piece 13 and the rear end of the elastic conducting piece 14 are in abutting fit and can be conducted. When the LED module is assembled, firstly, the support frame 11 is horizontally placed, the front side surface of the support frame 11 faces upwards, a worker puts the grounding piece 13 and the elastic conducting piece 14 into the accommodating hole 12, then the LED lamp panel 20 is fixedly connected to the front side surface of the support frame 11, at the moment, the front end of the elastic conducting piece 14 is in abutting fit with the LED lamp panel 20 and can conduct, the grounding piece 13 is positioned at an extending position penetrating through the accommodating hole 12, and the LED lamp panel 20 and the support structure 10 form the LED module; then, the LED module is fixedly connected to the LED box 30, and the LED box 30 is tightly attached to the LED box 30, so that the grounding piece 13 can be extruded by the LED box 30, and the grounding piece 13 moves to a retracted position, so that conduction among the LED lamp panel 20, the elastic conduction piece 14, the grounding piece 13 and the LED box 30 is realized. Because the elastic conduction piece 14 continuously abuts against the grounding piece 13, the grounding piece 13 and the LED box 30 are always in a conduction state, and the LED module and the LED box 30 are always in a grounding state. Therefore, the technical scheme of the embodiment can effectively solve the problem that the grounding structure in the related technology is easy to generate poor contact.

In this context, "front" in the description of the orientation refers to a direction of the LED display device toward the viewer in use, and "rear" refers to a direction of the LED display device away from the viewer in use. The above-mentioned "kept in the extended position" means that the LED module is kept in the extended position without external force (for example, in a case where the LED module is not mounted on the LED housing and the ground member is not abutted by other structures than the elastic member).

As shown in fig. 1 to 4, in the present embodiment, the rear end of the grounding member 13 includes a abutment curved surface 131.

The grounding member 13 has a spherical structure, and the inclined step surface 1211 can be adapted to the shape of the grounding member 13, and the inner contour of the inclined step surface 1211 is a part of the outer contour of the cone.

The copper layer structure enables conductive connection between the LED lamp panel 20 and the elastic conductive member 14.

As shown in fig. 3 to 4, the supporting frame 11 has a rectangular structure, and receiving holes 12 are provided at four corners of the rectangular structure. Because the four corners of the rectangular structure are provided with the accommodating holes 12, the accommodating holes 12 at the four corners are internally provided with the elastic conducting piece 14 and the grounding piece 13, thereby forming an electromagnetic shielding area, and the electromagnetic shielding area can cover the whole rectangular structure, so that the function of eliminating static electricity on the LED display device is realized.

As shown in fig. 3 to 6, the support frame 11 includes an outer frame 111, a plurality of vertical beams 112 arranged at intervals in the lateral direction, and a plurality of cross beams 113 arranged at intervals in the vertical direction, both ends of each vertical beam 112 and both ends of each cross beam 113 being connected to the outer frame 111. The vertical beams 112 and the cross beams 113 provide supporting foundation for the support frame 11 to support the LED lamp panel 20, and a hollow structure is formed between two adjacent vertical beams 112 and two adjacent cross beams 113, so that the weight of the support frame 11 can be reduced, and electric elements arranged on the rear surface of the LED lamp panel 20 can be avoided.

As shown in fig. 5 to 6, the LED module further includes a magnetic connection portion 40 and a positioning portion 50 disposed on the rear surface of the support frame 11, and the LED module is positioned and matched with the LED case 30 by the positioning portion 50 and is connected to the LED case 30 by the magnetic connection portion 40, and the magnetic connection portion 40 is a magnet. Since the LED housing 30 is made of a magnetic material, the magnetic connection portion 40 may be magnetically coupled to the LED housing 30 to fixedly connect the LED module to the LED housing 30. The positioning part 50 is a positioning pin, and the LED box 30 is provided with a positioning pin hole matched with the positioning pin in a positioning way, so that the LED module can be rapidly positioned with the LED box 30. In other embodiments, the magnetic connection part may be made of a magnetic material, and the LED case is correspondingly provided with a magnet part magnetically engaged with the magnetic connection part.

When the LED display device fails, a worker needs to perform post-maintenance on the LED display device, that is, detection maintenance on electrical components and the like inside the LED display device from the rear side of the LED display device. When the worker performs post-maintenance, since the LED module is magnetically connected with the LED box 30, in order to avoid the worker from loosening the LED module by mistake and dropping, the worker needs to temporarily use the fastener to pass through the first mounting hole 60 and the second mounting hole to fixedly connect the LED module to the LED box 30, so that the possibility of dropping the LED module is avoided; when the worker completes the maintenance, the fastener is removed and the state of the magnetic attraction connection between the LED module and the LED box 30 is restored.
