As shown in fig. 1 to 3, the rear case structure of the LED display device of the present embodiment includes: a frame 10 and a tipping 20. The frame 10 includes a back plate 11 and a frame 12 surrounding the edge of the back plate 11, and at least a portion of the frame 12 is located on the front side of the back plate 11. The edge 20 surrounds the frame 12. The edge 20 projects forwardly from the front surface of the frame 12. Wherein, a reinforcing structure 30 is arranged between the edge cover 20 and the frame 12.

By applying the technical scheme of the embodiment, in the process of processing the rear shell structure of the LED display device, the covered edge 20 and the frame 12 are of a split structure, so that the covered edge 20 can be made of a material different from the frame 12 and having a high strength, for example, the covered edge 20 can be made of a metal material which is not easy to break, and therefore, even if the thickness of the covered edge 20 is thin, the possibility of breaking of the covered edge 20 can be effectively avoided or reduced. In addition, a reinforcing structure 30 is arranged between the edge-covering 20 and the frame 12, and the reinforcing structure 30 is used for reinforcing the connection between the edge-covering 20 and the frame 12, so that the connection reliability between the edge-covering 20 and the frame 12 is ensured; meanwhile, the reinforcing structure 30 can also reinforce the strength of the wrapping 20 itself, so that the wrapping 20 is not easily deformed. Therefore, the technical scheme of the embodiment can solve the problem that the edge of the related art is easy to break.

As shown in fig. 2 to 6, the reinforcing structure 30 includes a reinforcing post 31 and a reinforcing hole 32. The reinforcing column 31 is inserted into the reinforcing hole 32, the reinforcing column 31 is provided in the bezel 12, and the reinforcing hole 32 is provided in the hem 20. In this way, the reinforcing column 31 is inserted into the reinforcing hole 32, the structural strength of the edge 20 can be increased, the adhesion force of the edge on the frame 12 can be increased, the edge 20 is installed outside the frame 12, the frame 10 and the edge 20 can be conveniently placed into an injection mold together, and the edge 20 and the frame 10 are directly injected and molded into a whole when the frame 10 is injected and molded.

Of course, in the embodiment not shown in the figures, the reinforcement holes may be provided in the frame and the reinforcement posts may be provided in the hem.

As shown in fig. 1 to 6, the covering edge 20 includes a strip-shaped plate 21 and a connecting structure 22. Wherein, the both ends butt joint cooperation of strip shaped plate 21, connection structure 22 sets up between strip shaped plate 21's both ends to connect strip shaped plate 21's both ends through connection structure 22. Thus, the strip-shaped plate 21 can be enclosed into a circle and directly enclosed outside the frame 12, so that the wrapping edge 20 is wrapped outside the front part of the frame 12.

As shown in fig. 2 and 6, the connecting structure 22 includes a connecting groove 221 and a connecting protrusion 222 mating with the connecting groove 221. The connecting groove 221 is disposed at a first end of the strip 21, and the connecting protrusion 222 is disposed at a second end of the strip 21. In this way, in the process that the strip-shaped plate 21 can be enclosed into a circle, the connecting protrusion 222 is spliced in the connecting groove 221, and two ends of the strip-shaped plate 21 can be reliably connected together. The splicing fitting of the connecting groove 221 and the connecting projection 222 means that the connecting projection 222 is located in the connecting groove 221, and the side wall surface of the connecting projection 222 contacts with the groove side wall surface of the connecting groove 221 to perform a tight splicing fitting, that is, the shape and size of the portion of the connecting projection 222 located in the connecting groove 221 are matched with the shape and size of the connecting groove 221. Of course, it may also mean that a part of the coupling projection is located outside the coupling groove, as long as a part of the sidewall surface of the coupling projection contacts with a part of the sidewall surface of the coupling groove to be coupled together, so that the strip can form a circle.

Of course, in the embodiment not shown in the figures, the connecting protrusion may be disposed at the first end of the strip-shaped plate, and the connecting groove may be disposed at the second end of the strip-shaped plate.

As shown in fig. 2 and 6, since the groove width of the connecting groove 221 is greater than the width of the notch 2212 of the connecting groove 221, the connecting protrusion 222 is located in the connecting groove 221, so that the connecting protrusion 222 can be caught by the notch 2212 of the connecting groove 221, the connecting protrusion 222 cannot be pulled out of the connecting groove 221 in the circumferential direction of the binding 20, and the reliability of connecting the two ends of the strip-shaped plate 21 together is ensured.

Note that the width of the connection groove 221 is the width of the connection groove 221 in the up-down direction in fig. 2. The fact that the width of the connecting groove 221 is greater than the width of the slot 2212 of the connecting groove 221 means that the width of the connecting groove 221 is greater than the width of its slot when it is unchanged, such as a "T" shaped groove. The connecting groove 221 has a maximum groove width that varies as compared to the width of its notch, e.g., a "dovetail" shaped groove.

As shown in fig. 2 and 6, the groove width of the connection groove 221 gradually decreases from the maximum groove width of the connection groove 221 to the direction of the notch 2212 of the connection groove 221. The coupling projection 222 includes a flared section 2221 fitted with the maximum groove width 2211 of the coupling groove 221 and a necked section 2222 fitted with the notch 2212 of the coupling groove 221. Like this, the lateral wall face of flaring section 2221 can contact with the inside wall face of maximum groove width department 2211, guarantees that the first end of BAR 21 and the second end of BAR 21 can be in the same place in face-to-face fit's butt joint. Meanwhile, the notches 2212 of the connecting groove 221 can clamp the neck-expanding section 2221, so that the maximum groove width position 2211 of the connecting protrusion 222 is prevented from being separated from the notches 2212 of the connecting groove 221 along the circumferential direction of the wrapping edge 20, and the two ends of the strip-shaped plate 21 can be reliably connected together.

As shown in fig. 2 and 6, the coupling protrusion 222 is spliced in the coupling groove 221 from the outside to the inside of the rim 20 to form a loop, and in order to ensure a large splicing area between the coupling groove 221 and the coupling protrusion 222, the coupling groove 221 is a circular segment-shaped groove, and the coupling protrusion 222 is a circular segment-shaped protrusion engaged with the circular segment-shaped groove, so that the coupling protrusion is formed in a circular segment shape. The connecting protrusion 222 and the connecting groove 221 can be in surface-to-surface contact, so that the first end of the strip-shaped plate 21 and the second end of the strip-shaped plate 21 are butted together and cannot be loosened, and the stability of splicing together is improved. The term "segment" in the segment-shaped groove and segment-shaped protrusion refers to a shape surrounded by a remaining portion of a whole circle from which a portion having an area smaller than half is cut out.

As shown in fig. 1 to 6, the covering edge 20 is a metal member, and the frame 10 and the covering edge 20 are integrally formed. In this way, after the edge 20 of the metal member and the frame 10 are injection molded together, the structural strength of the edge 20 can be further improved, the possibility of fracture of the edge 20 is greatly reduced, and the yield of the rear shell structure of the LED display device is further improved. Thus, the thickness of the hem 20 can be made 0.3mm.

The application also provides an LED display device, as shown in fig. 7 to 10, the LED display device of the embodiment comprises a rear shell structure and a lamp panel module 40 arranged on the rear shell structure, and the rear shell structure is the rear shell structure of the LED display device. Due to the fact that the rear shell structure of the LED display device can solve the problem that the edge of the LED display device in the related art is prone to breaking, the LED display device with the rear shell structure can solve the same technical problem.

As shown in fig. 7 to 10, the lamp panel module 40 is installed at the front side of the frame 10 of the rear shell structure, and is located in the edge 20 of the rear shell structure, and the edge 20 is adhesively connected to the outer side wall of the frame 10. Like this, 20 of borduring also can be with the lateral wall parcel of lamp plate module 40, protect the lateral wall of lamp plate module 40. Specifically, the edge 20 is adhesively connected to the outer side wall of the frame 10 by glue filling.
