Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] like Figures 2 to 4 As shown, the present invention provides an LED display module bottom shell structure, including a bottom shell 1. The bottom shell 1 is provided with two power signal openings 11 arranged symmetrically on the left and right. The outer periphery of the power signal opening 11 is provided with a plurality of bottom shell locking holes 12 for locking to the housing 20. In this embodiment, the outer periphery of the power signal opening 11 is provided with four bottom shell locking holes 12.

[0028] The outer periphery of the power signal opening 11 is further provided with a rubber ring mounting groove 13, and the bottom shell locking hole 12 is located in the rubber ring mounting groove 13; the rubber ring mounting groove 13 is used for mounting a sealing rubber ring 14; the sealing rubber ring 14 is shaped to adapt to the shape of the rubber ring mounting groove 13, and the sealing rubber ring 14 is provided with a rubber ring through hole 141 corresponding to each bottom shell locking hole 12.

[0029] In the embodiment, the left and right sides of the bottom shell 1 are respectively provided with the power signal opening 11; the bottom shell 1 comprises two sealing rubber rings 14, a rubber ring fixing plate 15 and four connecting screws 16; the two sealing rubber rings 14 are respectively mounted in the rubber ring mounting grooves 13 of the two power signal openings 11; referring to Figure 6 One of the power signal openings 11 is connected with the cabinet 20 and fixes one of the sealing rubber rings 14, and the other power signal opening 11 fixes the other sealing rubber ring 14 by using the rubber ring fixing plate 15; the rubber ring fixing plate 15 is provided with four fixing plate through holes 151 corresponding to the four bottom shell locking holes 12 on the outer periphery of the power signal opening 11, and each connecting screw 16 is locked in the bottom shell locking hole 12 through the fixing plate through hole 151.

[0030] Therefore, referring to Figure 7 When the LED display module 10 with the bottom shell structure is assembled with the power interface of the cabinet 20, the mounting screw 30 can pass through the outer periphery of the power interface of the cabinet 20 and be locked on the bottom shell locking hole 12 on the outer periphery of the power signal opening 11 on one side, at this time, the sealing rubber ring 14 can be clamped and fixed between the cabinet 20 and the bottom shell 1, and the position accuracy and sealing performance during installation of the sealing rubber ring 14 can be enhanced by means of the rubber ring through hole 141; the other power signal opening 11 which is not assembled with the power interface of the cabinet 20 can be closed and protected by the following rubber ring fixing plate 15, the rubber ring fixing plate 15 fixes the sealing rubber ring 14 by means of the existing bottom shell locking hole 12, without the need to additionally open a screw hole, and part of the connecting screw 16 can be saved, thereby saving costs.

[0031] Meanwhile, 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 bottom shell 1 can be prevented from being deformed during molding or locking, and the problem of uneven ink color caused by local concave of the module can be solved.

[0032] One side wall of the power signal opening 11 is provided with a boss 18, and the two ends of the connecting rib 17 are respectively connected to the boss 18 and the opposite side wall of the boss 18.

[0033] 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. The four bottom housing locking holes 12 are located within the four extending grooves 132. By setting the "well" shaped rubber ring mounting groove 13, the existing bottom housing locking hole 12 layout is not required; only the outer periphery of the power signal opening 11 needs modification, thus saving product improvement costs. Simultaneously, 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.

[0034] 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.

[0035] 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; the ring fixing plate 15 is rectangular, and the through holes 151 of each fixing plate are located at the four corners of the ring fixing plate 15.

[0036] like Figures 5 to 7 As shown, this utility model also provides an LED display module 10, including a face mask 2, a lamp board 3 and the bottom shell 1; the face mask 2, the lamp board 3 and the bottom shell 1 are all provided with indicator arrows 40 for indicating the installation direction; in this embodiment, the face mask 2, the lamp board 3 and the bottom shell 1 are all square.

[0037] Therefore, during installation, the LED display module 10 allows for convenient assembly of its components via the indicator arrows 40. (See also...) Figure 6 A total of four LED display modules 10 can be installed on the cabinet 20. The diagram shows an example of installing two.
