DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantage of the embodiment of the application more clear, the technical scheme in the embodiment of the application will be clearly and completely described below in conjunction with the drawings in the embodiment of the application, obviously, the described embodiment is a part of the embodiment of the application, rather than all the embodiments. The components of the embodiment of the application described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] As Figures 2 to 4 Indicated, a kind of LED display module 10 of the utility model, including face guard 2, PCB board 3 and bottom shell 1.

[0025] The bottom shell 1 is equipped with a power signal opening 11, the power signal opening 11 is located in the side of bottom shell 1, the face guard 2, PCB board 3 and bottom shell 1 are all equipped with the indication arrow R for prompting installation direction;The face guard 2, PCB board 3 and bottom shell 1 of the embodiment are all square.

[0026] Therefore, referring to Figure 3 , the indication arrow R of the face guard 2 and PCB board 3 and the indication arrow R of bottom shell 1 are assembled in the same direction or reverse when the LED display module 10 is installed, that is, face guard 2 positive installation + bottom shell 1 positive installation or face guard 2 positive installation + bottom shell 1 reverse installation, thereby, the display module 10 that power signal opening 11 is located in left side or right side can be formed.

[0027] Therefore, through the indication arrows R, the assembly operation of each component can be facilitated. Specifically, in the embodiment, the power signal opening 11 is located on the right side of the back of the bottom shell 1. Through the assembly of the front mask 2 and the front bottom shell 1 and the assembly of the front mask 2 and the reverse bottom shell 1, the display module 10 can be installed on the right / left side of the box 20 using a structure of the bottom shell, which can save the mold cost. Compared with the two power signal openings 11 of the prior art, the present scheme has one less power signal opening 11, and accordingly one sealing ring 14 and one ring cover plate (not shown in the figure) are saved, which can reduce the product cost and improve the assembly efficiency of the display module 10 and the box 20.

[0028] Referring to Figure 4 , the box 20 can install four LED display modules 10 in total, and two are installed as an example for illustration. The power signal openings 11 of the two display modules 10 shown in the figure are divided into right and left sides of the front mask 2 in the front to be connected and matched with the power interface 201 in the middle of the box 20.

[0029] As Figure 2 shown, the front of the bottom shell 1 is provided with a plurality of front locking holes 15 for locking the PCB 2. Each front locking hole 15 is a symmetrical structure along the center line M of the bottom shell. The power signal opening 11 is arranged on the back of the bottom shell 1.

[0030] As Figure 5 and Figure 6 shown, the middle area inside the power signal opening 11 of the embodiment is provided with a connecting rib 17. Therefore, the structural strength can be improved, the deformation of the bottom shell 1 during molding or locking can be prevented, and the problem of uneven ink color caused by local concave of the module can be solved.

[0031] One side wall of the power signal opening 11 is provided with a boss 18. The connecting rib 17 is connected to the boss 18 and the opposite side wall of the boss 18 at both ends.

[0032] The outer periphery of the power signal opening 11 is provided with a plurality of bottom shell locking holes 12 for locking the box 20.

[0033] The outer periphery of the power signal opening 11 is further provided with a ring mounting groove 13, and the bottom shell locking hole 12 is located in the ring mounting groove 13. The ring mounting groove 13 is used for mounting a sealing ring 14. The sealing ring 14 is adapted to the shape of the ring mounting groove 13, and the sealing ring 14 is provided with a ring through hole 141 corresponding to each bottom shell locking hole 12.

[0034] Specifically, the rubber ring mounting groove 13 can be approximately shaped like a "well". The rubber ring mounting groove 13 includes a rectangular frame groove 131 and four extending grooves 132. The rectangular frame groove 131 surrounds the outer periphery of the power signal opening 11, and each extending groove 132 is located outside the four corners of the rectangular frame groove 131 and connects to the four corners. Four bottom shell locking holes 12 are provided around the outer periphery of the power signal opening 11; the four bottom shell locking holes 12 are located within the four extending grooves 132. By setting the rubber ring mounting groove 13 in a "well" shape, the width of the main rectangular frame groove 131 of the rubber ring mounting groove 13 can be reduced, thereby saving material costs for the sealing rubber ring 14.

[0035] A bottom housing locking post 19 protrudes from the extended groove 132, and the bottom housing locking hole 12 is located on the bottom housing locking post 19; the sealing ring 14 has a through hole 141 through which the bottom housing locking post 19 passes. This facilitates the alignment and installation of the sealing ring 14.

[0036] The thickness of the sealing ring 14 is greater than the thickness of the ring mounting groove 13 to enhance the sealing effect, which can prevent water and dust, and ensure the reliability of the circuit connection.
