In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The utility model provides an outdoor LED display module, as shown in FIG. 1, including drain pan 1 and top cap 2, drain pan 1 is connected with top cap 2 and is formed the casing, and the built-in LED display module of casing sets up guiding gutter 3 around the casing, and the top of top cap 2 upper end protrusion drain pan 1 forms breakwater 21, and the lower extreme indent of top cap 2 forms installation step 22 in the bottom of drain pan 1, and the size of top cap 2 upper end protrusion drain pan 1 equals the size of top cap 2 lower extreme indent in drain pan 1.
An outdoor LED display screen is shown in fig. 2 and 3, and comprises a plurality of LED display modules 7, wherein the LED display modules 7 are spliced and are connected through stainless iron guide grooves 4 to form the LED display screen, a water baffle 21 of the next LED display module 7 is inserted into a mounting step 22 of the upper LED display module 7, and the stainless iron guide grooves 4 are vertically arranged along the splicing positions of the adjacent two rows of LED display modules 7, so that powerful magnets 5 on the LED display modules 7 are connected with the stainless iron guide grooves 4.

The outer shell of the LED display module is accommodated with a waterproof effect, wherein the diversion trenches 3 on the side surfaces of the bottom shell 1 and the top cover 2 are spliced to form a circle of waterproof, water-guiding and water-draining grooves around the shell, so that water around the LED display module 7 flows into the diversion trenches 3 through the diversion trenches 3 and flows downwards along the diversion trenches 3 to the two sides in the vertical direction, and finally the range of the LED display module 7 is discharged. The structure of the diversion trench 3 can well play a role in diversion in the outdoor rainy day environment, rainwater on the LED display module 7 can quickly and intensively flow into the waterproof tank when flowing along the LED display module 7, and along with accumulation of the rainwater, water flow is automatically formed to flow along the waterproof tank, and naturally falls along the edge of the LED display module 7. Because the height of the water baffle 21 is far higher than the end face of the diversion trench 3, under the condition of large water flow, the water flow cannot overflow to influence various plugging electrical ports on the other end face of the top cover 2.
In addition, the shape fit between the water baffle 21 and the mounting step 22 is beneficial to adjusting the relative position between the LED modules. In the process of splicing the plurality of LED display modules 7 to form the LED display screen, the LED display module 7 of the upper layer and the LED display module 7 of the lower layer can be directly spliced, but not spliced by limiting the relative positions of an external frame or other structures. The upper end of the top cover 2 protrudes out of the bottom shell 1, and the lower end of the top cover is inwards concave in the design of the bottom shell 1, so that when the upper layer of LED display modules 7 and the lower layer of LED display modules 7 are spliced, the water baffle 21 of the lower layer of LED display modules 7 can be inserted into the mounting step 22 of the upper layer of LED display modules 7, and the upper layer of LED display modules 7 and the lower layer of LED display modules 7 can be spliced. Because the installation step 22 is in an assembly relation with the water baffle 21, that is, the size of the end part of the installation step 22, which is concave in the bottom shell 1, is the same as the size of the end part, higher than the bottom shell 1, of the water baffle 21, and the thickness of the water baffle 21 is the same as the thickness of the installation step 22, so that the front end face and the rear end face of the upper LED display module 7 and the lower LED display module 7 can be guaranteed to be flush after assembly, the distance between the upper LED display module 7 and the lower LED display module 7 is certain, the reference surface of the LED module is not required to be horizontally corrected, and the limitation and bearing installation of the positions between the LED modules are not required to be realized through the box body structure of the metal frame.

The top cover 2 is provided with a power supply plug-in port 25, a signal output plug-in port 24 and a signal input plug-in port 23, the power supply plug-in port 25 is connected with the power supply input port, the signal output plug-in port 24 is connected with the signal output port, and the signal input plug-in port 23 is connected with the signal input port.
The other end face of the top cover 2 far away from the bottom shell 1 is provided with a plurality of powerful magnets 5, and the powerful magnets 5 are arranged at the two side edges of the top cover 2 of the LED display module 7. In this embodiment, the strong magnet 5 has a smaller diameter at one end and a larger diameter at the other end, and the smaller diameter end is provided with a connecting thread, so that the strong magnet 5 is connected with the top cover 2 through the connecting thread. In other embodiments, the powerful magnet 5 is of various shapes and structures, and can be stably arranged on the top cover 2 and connected with the stainless iron diversion trench 4.

In addition, the thickness of the groove-like structure is larger than the depth of the recess, and the recess is a connection point of the strong magnet 5, and the thickness is set to enhance the connection strength with the strong magnet 5. On the other hand, the structure of the LED display module 7 adopted by the invention is a box-free structure, and a metal frame and a steel structure with large weight are not existed, so that the connection of the LED display module 7 can be completed through the powerful magnet 5, and the adsorption force of the powerful magnet 5 can meet the requirement of connection strength.

When the LED display modules 7 are spliced to form the LED display screen, the formed reticular flow passage can effectively dredge rainwater and prevent the accumulation of the rainwater. On the other hand, the LED display module 7 forming the LED display screen is high in splicing compactness, high in flatness, high in rainwater downstream capability and low in rainwater accumulation capability, and in addition, the rainwater can quickly flow out of the area where the LED display screen is located due to the drainage effect of the diversion trench 3. In addition, the stainless iron diversion trench 4 with the groove-shaped structure can form a relatively closed drainage flow channel with the vertical diversion trench 31, so that overflow and splashing of water in the process of large water flow are prevented, and the waterproof performance of the LED display screen is improved.

In addition, the LED display module 7 is characterized by further comprising a bending arrangement of the bottom shell 1 and the water baffle 21, wherein the relative installation position and mode of the water baffle 21 and the installation step 22 are not changed, and the radian of the LED display modules 7 in the same row on the LED display screen is the same, so that longitudinal splicing is facilitated. The LED display module 7 constituting the curved screen in the present embodiment is higher in terms of compatibility than a flat screen.
