The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.

[0045] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0046] Reference Figures 1 to 8 As shown in the figure, this utility model embodiment proposes an outdoor LED display screen, which includes: a cabinet 100, a lamp board module 200, a sealing component 300, and circuit elements 400.

[0047] The housing 100 includes a main body groove 110 and a sealing groove 120 disposed within the main body groove 110. The main body groove 110 includes a first mounting opening and a decorative outer surface 111 away from the first mounting opening. The sealing groove 120 has a second mounting opening, and the second mounting opening and the first mounting opening have the same orientation. In this embodiment, the housing 100 is rectangular. The main body groove 110 forms the outer contour of the housing 100 and includes a bottom plate 112 and a first peripheral plate 113 connected to the bottom plate 112 at one end. The other end of the first peripheral plate 113 surrounds to form the first mounting opening. The sealing groove 120 is disposed in the middle of the bottom plate 112 to facilitate the connection of the lamp panel module 200. The sealing groove 120 includes a second peripheral plate 121, one end of which is connected to the bottom plate 112, and the other end of which forms the second mounting opening. The second peripheral plate 121 can be composed of a separate plate or can be formed together with the first peripheral plate 113; the sealing groove 120 can also be provided at the edge of the base plate 112 or other positions.

[0048] The lamp panel module 200 is connected to the housing 100 and covers the first mounting port. The lamp panel module 200 has a display surface away from the first mounting port. The lamp panel module 200 displays preset content through the display surface to meet usage requirements. The lamp panel module 200 is an integrated component, with multiple LEDs integrated into the lamp panel module 200.

[0049] The sealing component 300 is disposed between the lamp panel module 200 and the sealing groove 120, and the sealing cover is disposed on the second mounting port. The sealing component 300 and the sealing groove 120 together form a mounting cavity, and the sealing component 300 and the sealing groove 120 jointly seal the mounting cavity, so that the mounting cavity has better sealing performance.

[0050] The circuit element 400 is located in the mounting cavity and electrically connected to the lamp panel module 200. The circuit element 400 is sealed through the mounting cavity, making it less susceptible to interference from rainwater and more reliable in use.

[0051] It is understandable that the circuit element 400 is located within the sealing groove 120. During the installation of the sealing groove 120, the sealing assembly 300, and the lamp board module 200, the circuit element 400 is directly sealed within the mounting cavity, thereby achieving the sealing of the circuit element 400 and improving the overall sealing performance of the outdoor LED display. At the same time, the lamp board module 200 covers the main body groove 110, so that the connection structure inside the cabinet 100 is hidden, which makes the outer surface of the outdoor LED display more beautiful. The back of the outdoor LED display will also be decorated with a decorative outer surface 111 to improve the overall aesthetics.

[0052] Reference Figure 2 , Figure 4 , Figure 5and Figure 6 As shown, in some specific embodiments of this utility model, the sealing assembly 300 includes a sealing plate 310 and a first sealing ring 320. The first sealing ring 320 is disposed between the sealing plate 310 and the sealing groove 120 and is pressed and fixed by the sealing plate 310 and the sealing groove 120.

[0053] It is understandable that by improving the sealing performance between the sealing plate 310 and the sealing groove 120 through the first sealing ring 320, moisture is less likely to enter the installation cavity through the gap between the sealing plate 310 and the sealing groove 120.

[0054] In this embodiment, the other end of the second peripheral plate 121 has an annular groove along the axial direction of the second peripheral plate 121. The first sealing ring 320 can be directly placed in the annular groove to position the first sealing ring 320. When the sealing plate 310 covers the other end of the second peripheral plate 121 and closes the second mounting port, the sealing plate 310 squeezes the first sealing ring 320, so that the first sealing ring 320 plays a sealing role.

[0055] In addition, the sealing plate 310 and the sealing groove 120 are also fixed by bolts. The bolts are located at the outer edge of the sealing plate 310 and the outer edge of the second peripheral plate 121, so that the bolts are outside the first sealing ring 320 and will not affect the sealing performance of the first sealing ring 320.

[0056] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some specific embodiments of this utility model, the lamp panel module 200 includes a main lamp panel portion 210 and a first magnetic suction portion 220 disposed on the side of the main lamp panel portion 210 facing the first mounting port; the sealing assembly 300 includes a sealing plate 310, the sealing plate 310 includes a main board portion 311 and a second magnetic suction portion 312 disposed on the main board portion 311, the second magnetic suction portion 312 being magnetically connected to the first magnetic suction portion 220.

[0057] It is worth understanding that during the installation of the sealing plate 310, the first magnetic part 220 and the second magnetic part 312 can play a guiding role, making it easier to determine the relative position of the sealing plate 310 and the lamp panel module 200, thus improving the ease of installation.

[0058] In this embodiment, the first magnetic suction part 220 includes a magnetic steel column disposed on the main lamp panel part 210. The first magnetic suction part 220 is directly fixed to the main lamp panel part 210, and the second magnetic suction part 312 is directly fixed to the sealing plate 310. The specific fixing method of the first magnetic suction part 220 and the second magnetic suction part 312 can be integral molding, bonding, locking, etc. Both the first magnetic suction part 220 and the second magnetic suction part 312 can be magnets, or one of them can be a magnet and the other can be iron.

[0059] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some specific embodiments of this utility model, the lamp panel module 200 includes a main lamp panel portion 210, a first electrical connector portion 230 disposed on the main lamp panel portion 210, and a first connector portion 240 surrounding the first electrical connector portion 230; the sealing assembly 300 includes a sealing plate 310 and a second sealing ring 330, the sealing plate 310 including a main board portion 311 and a second connector portion 313 disposed on the side of the main board portion 311 facing the lamp panel module 200, the first... The second plug-in portion 313 has a through hole, and the second plug-in portion 313 is inserted into the first plug-in portion 240. The second sealing ring 330 is disposed between the first plug-in portion 240 and the second plug-in portion 313, and is pressed and fixed by the first plug-in portion 240 and the second plug-in portion 313. The circuit element 400 includes a circuit board 410 and a second electrical plug-in portion 420 disposed on the circuit board 410. The second electrical plug-in portion 420 passes through the through hole and is inserted into the first electrical plug-in portion 230.

[0060] It is understandable that after the second plug-in part 313 is plugged into the first plug-in part 240, the through hole forms a closed connection channel. The first electrical plug-in part 230 and the second electrical plug-in part 420 are inserted into the connection channel to realize the electrical connection between the main lamp board part 210 and the circuit element 400, so as to control and power the main lamp board part 210.

[0061] Reference Figure 5 and Figure 6 As shown, in some specific embodiments of this utility model, the second sealing ring 330 is disposed between the circumferential surface of the first insertion portion 240 and the circumferential surface of the second insertion portion 313 and is pressed and fixed by the two circumferential surfaces. The second sealing ring 330 includes a main ring portion 331 and a sealing protrusion 332. The sealing protrusion 332 is disposed on the circumferential surface of the main ring portion 331 and surrounds the main ring portion 331 in the circumferential direction. The second sealing ring 330 includes one sealing protrusion 332, or the second sealing ring 330 includes multiple sealing protrusions 332, and the multiple sealing protrusions 332 are distributed sequentially at intervals along the axial direction of the main ring portion 331.

[0062] In this embodiment, the first insertion part 240 is female, the second insertion part 313 is male, and the second sealing ring 330 is sleeved on the outer peripheral surface of the second insertion part 313. When the second insertion part 313 is inserted into the first insertion part 240, the second sealing ring 330 is squeezed by the outer peripheral surface of the second insertion part 313 and the inner peripheral surface of the first insertion part 240, so that the second sealing ring 330 plays a sealing role. At the same time, the size of the second sealing ring 330 being squeezed is positively correlated with the relative portion of the outer peripheral surface of the second insertion part 313 and the inner peripheral surface of the first insertion part 240, so that the second sealing ring 330 can have a larger sealing area and the sealing effect is further improved.

[0063] The second sealing ring 330 has three sealing protrusions 332, each of which can perform a sealing function, achieving multiple seals and making the sealing effect of the second sealing ring 330 better. The second sealing ring 330 may also have one, two, or four or more sealing protrusions 332.

[0064] In another embodiment, the first insertion portion 240 is male, the second insertion portion 313 is female, and the second sealing ring 330 is sleeved on the outer peripheral surface of the first insertion portion 240. Alternatively, the second sealing ring 330 is nested within the second insertion portion 313. The second sealing ring 330 may have a sealing protrusion 332 on its outer peripheral surface, a sealing protrusion 332 on its inner peripheral surface, or both its outer and inner peripheral surfaces may have sealing protrusions 332.

[0065] Reference Figure 2 , Figure 7 and Figure 8 As shown, in some specific embodiments of this utility model, the housing 100 includes a third magnetic suction part disposed within the main body groove 110; the lamp panel module 200 includes a main lamp panel 210 and a fourth magnetic suction part 250 disposed in the main lamp panel 210, the fourth magnetic suction part 250 being magnetically connected to the third magnetic suction part.

[0066] It is worth understanding that the magnetic connection between the third magnetic part and the fourth magnetic part 250 makes it easier to position the main lamp panel 210 and the main body groove 110, which is more conducive to the assembly and positioning of the lamp panel module 200 and the housing 100, and improves the ease of installation.

[0067] In this embodiment, the lamp panel module 200 also includes a mounting hole provided in the main lamp panel portion 210. The main body groove portion 110 has a mounting post. One end of the mounting post is connected to the base plate 112 and / or the circumferential surface is connected to the first peripheral plate 113. The end of the mounting post away from the base plate 112 has a threaded hole. The mounting hole can be aligned with the threaded hole and locked by bolts to realize the fixed connection between the lamp panel module 200 and the housing 100.

[0068] Reference Figure 2 and Figure 4 As shown, in some specific embodiments of this utility model, the circuit element 400 includes a circuit board 410, a connecting wire harness 430 electrically connected to the circuit board 410, and a third sealing ring 440. The connecting wire harness 430 passes through the sealing groove 120 and the main body groove 110, and has a connector for electrical connection outside the housing 100. The third sealing ring 440 is disposed between the connecting wire harness 430 and the sealing groove 120, and is squeezed and fixed by the connecting wire harness 430 and the sealing groove 120.

[0069] It is worth understanding that the third sealing ring 440 seals the gap between the connecting wire harness 430 and the sealing groove 120, so that the mounting cavity can be in a sealed state, and the circuit board 410 and other components are less susceptible to moisture, resulting in better sealing performance of the mounting cavity.

[0070] In this embodiment, the third sealing ring 440 is annular and has an annular groove on its outer circumferential surface. The sealing groove 120 has a wire harness hole. The inner circumferential surface of the wire harness hole can fit into the annular groove and together with the connecting wire harness 430, press the annular groove to achieve the sealing of the connecting wire harness 430.

[0071] In addition, the circuit element 400 also includes a power module 450, which is disposed within the sealing groove 120 and electrically connected to the circuit board 410.

[0072] Reference Figure 8 As shown, in some specific embodiments of this utility model, the lamp panel module 200 includes a main lamp panel portion 210, which includes a bottom shell 211, a driving lamp panel 212, and an adhesive layer. The adhesive layer is disposed between the bottom shell 211 and the driving lamp panel 212 and can seal the gap between the driving lamp panel 212 and the bottom shell 211.

[0073] It is worth understanding that by sealing the gap between the drive lamp board 212 and the bottom shell 211 with an adhesive layer, the connection between the drive lamp board 212 and the bottom shell 211 becomes tighter, and the overall sealing performance of the lamp board module 200 is better, effectively preventing rainwater from entering and causing equipment failure, thereby improving the reliability and safety of the lamp board module 200.

[0074] Reference Figure 7 and Figure 8 As shown, in some specific embodiments of this utility model, the lamp panel module 200 includes a main lamp panel portion 210, a third electrical connector portion 260 disposed on the main lamp panel portion 210, a cover member 270, and a fourth sealing ring 280. The cover member 270 covers the third electrical connector portion 260, and the fourth sealing ring 280 is disposed between the cover member 270 and the main lamp panel portion 210 and is pressed and fixed by the cover member 270 and the main lamp panel portion 210.

[0075] It should be noted that the lamp board module 200 includes two main lamp board sections 210. Each main lamp board section 210 has four electrical connectors. However, in use, two electrical connectors are sufficient to meet the usage requirements. Therefore, the two first electrical connectors 230 of the main lamp board section 210 are electrically connected to the circuit board 410, and the other two third electrical connectors 260 need to be sealed.

[0076] In this embodiment, the third electrical connector 260 is sealed by the cover 270 and the fourth sealing ring 280, thereby improving the safety of the lamp board module 200.

[0077] Reference Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, the decorative outer surface 111 has a heat dissipation portion 1111, and the direction perpendicular to the decorative outer surface 111 is defined as the projection direction. The projection of the heat dissipation portion 1111 along the projection direction at least partially coincides with the projection of the sealing groove portion 120 along the projection direction.

[0078] It is understandable that the heat dissipation part 1111 can improve the heat dissipation efficiency of the circuit element 400 within the sealing groove part 120 and improve the reliability of the circuit element 400.

[0079] In this embodiment, the heat dissipation portion 1111 increases the contact area between the decorative outer surface 111 and the air, and the heat dissipation portion 1111 is evenly arranged throughout, improving aesthetics and enabling the heat dissipation portion 1111 to serve both a heat dissipation function and a decorative function. Specifically, the heat dissipation portion 1111 includes a plurality of heat dissipation grooves evenly spaced along the same direction.

[0080] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
