Description

Technical Field

[0001] This application relates to the field of imaging technology, and particularly to an LED display device. Background Art

[0002] LED display screens are favored by a wide range of users due to their high brightness, low operating voltage, low power consumption, large size, long lifespan, impact resistance, and stable performance. With the rapid development of the entertainment and advertising industries, especially in television stations, evening party sites, stages, or large outdoor advertising sites, large-screen displays are required. However, large-screen displays mean an increase in the number of circuits and the volume of the power supply system, thus requiring a large installation space for the power supply system while ensuring the stability of the display device. Moreover, when the power supply system powers the display to show images, static electricity is easily generated, which can adsorb external dust and damage the device.

[0003] For example, in the patent with the application number CN202320079507.5, an assembled LED display device has the following deficiencies in actual use:

[0004] This patent forms a snap connection through the groove opened in the support frame and the snap connector, so that the snap connector drives the entire display screen to be snap-connected to the surface of the support frame to form a fixation. However, as the usage area of the display screen increases, the volume of devices such as power lines also increases synchronously. This device lacks a protective storage space for the power line device, and at the same time, the fixing method is single, which easily causes shaking during the display of the display screen and reduces the viewing performance. Summary of the Utility Model

[0017] By adopting the above technical solution, the wires inside the main frame pass through the interaction holes and are connected to the lamp bodies in the display frame, thereby providing a circuit space for power transmission.

[0018] Preferably, mounting holes are formed at the positions of the plurality of side plates on the surface of the main frame, and screws for connecting the side plates are arranged in the mounting holes.

[0019] By adopting the above technical solution, the plurality of mounting holes are opposite to the plurality of side plates, thereby providing mounting fulcrums for the fixation of the side plates.

[0020] Preferably, a plurality of adjusting tubes are fixedly arranged at the top of the outer surface of the main frame, and the bottoms of the plurality of adjusting tubes surround the side plates and are connected to the display frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following further describes the present application in detail Figures 1 - 5 in conjunction with the attached drawings.

[0034] The embodiment of the present application discloses an LED display device.

[0035] Refer to Figure 1, Figure 2 , an LED display device, including a connecting frame 1, the connecting frame 1 is composed of multiple vertical rod parts, mounting seats 15 are fixed to the rod surfaces at the top of the connecting frame 1 by screws, and four threaded holes are provided on the surface of the mounting seat 15, and are fixedly connected to the ceiling by screwing screws into the threaded holes. Fixed cross beams 2 (the number of fixed cross beams 2 is at least four) are fixedly arranged in pairs at the bottoms of the rod surfaces of the connecting frame 1, and fixing gaskets 14 are connected by screws on both sides of the connection points between the multiple fixed cross beams 2 and the connecting frame 1. Two fixed longitudinal beams 3 are connected to the upper surfaces of the multiple fixed cross beams 2, and the multiple fixed cross beams 2 and the fixed longitudinal beams 3 are arranged at 90°. And connecting rods 4 are fixed to the intersection points of the multiple fixed cross beams 2 and the fixed longitudinal beams 3 by screws.

[0036] The top of the mounting seat 15 is fixedly connected to the ceiling, thereby driving the whole connecting frame 1 to be fixed. And the top of the mounting seat 15 is flat to increase the connection area with the ceiling and increase the fixing area of the connecting frame 1. The fixing gasket 14 connects the connecting frame 1 and the multiple fixed cross beams 2. While fixing the multiple fixed cross beams 2 as a whole, the fixed cross beams 2 and the connecting frame 1 are connected at 90° to form a horizontal fixation. Then the fixed longitudinal beams 3 and the fixed cross beams 2 are cross-connected, so that the fixed longitudinal beams 3 and the fixed cross beams 2 are at 90°, forming a longitudinal fixation to improve the stability. The connecting rod 4 is welded and fixed at the intersection of the fixed longitudinal beam 3 and the fixed cross beam 2, so that while the whole body is fixedly connected to the connecting frame 1, it helps to improve the stability.

[0037] Refer to Figure 2 , Figure 3 , a main frame 5 is fixedly arranged at the bottom of the connecting rod 4. The main frame 5 is a rectangular frame body composed of multiple connecting rods, and there are multiple frame cells in the frame. A power transmission system and a lighting control system for connecting LED lights are installed inside the main frame 5. A plurality of mounting holes 13 are provided on the outer surface of the main frame 5. Side plates 6 are fixedly arranged in the multiple frame cells on the outer surface of the main frame 5. And each side plate 6 is fixed to the main frame 5 by screwing into the mounting holes 13. Normally, the outer surface of the side plate 6 is flush with the outer surface of the main frame 5. A bottom plate 7 is fixed to the bottom of the main frame 5 by screws. A plurality of interaction holes 8 are arranged in a row on the upper surface of the bottom plate 7, and the interaction holes 8 penetrate through the bottom of the bottom plate 7. At the same time, display frames 9 are fixed to the bottom of the bottom plate 7 around the multiple interaction holes 8. And the inside of the display frame 9 is communicated with the interaction holes 8. An LED display board 16 is fixedly arranged in each display frame 9.

[0038] The main frame 5 reserves a fixed space for the installation of the power transmission system and the lighting control system. At the same time, multiple side plates 6 are fixedly wrapped around the side surface of the main frame 5, and cooperate with the bottom plate 7 to wrap the surface of the main frame 5, forming a semi-closed state for the power transmission system and the lighting control system, which plays a protective role and is convenient for personnel to disassemble and maintain. And the interaction holes 8 communicate the inside of the main frame 5 with the display frame 9, so that the circuit of the power transmission system is docked with the LED display board 16 through the interaction holes 8, so as to perform lighting display.

[0039] It should be noted that the number of the display frames 9 and the interaction holes 8 is adjusted according to the lighting layout. At the same time, the circuit of the power transmission system passes through the interaction holes 8 and is docked with the LED display board 16.

[0040] Refer to Figure 4 、 Figure 5 At the four diagonal corners of the outer surface of the main frame 5, 90° grooves are provided, and a rectangular fixing column 11 is welded and fixed in each groove. The fixing column 11 is hollow inside, and a support plate 12 is fixedly arranged on the inner wall of the hollow of the fixing column 11. The support plate 12 is made of steel and has good bending resistance and load-bearing capacity. At the same time, a circle of baffles is fixedly arranged around the main frame 5 at the top around multiple connecting rods 4. A plurality of adjusting tubes 10 are connected to the surface of the baffle. The tops of the plurality of adjusting tubes 10 all penetrate through the baffle and are connected to the lighting control system. The bottoms of the plurality of adjusting tubes 10 are all located at the bottom of the main frame 5 around the side plates 6, and the part of the adjusting tube 10 located at the bottom of the main frame 5 penetrates through the display frame 9 and is docked with the LED display board 16.

[0041] The four fixing columns 11 are welded at the diagonals of the main frame 5, thereby improving the stability of the main frame 5. And the support plate 12 is inclined and arranged inside the fixing column 11, thereby assisting in improving the supporting force of the fixing column 11. At the same time, the baffle assists in fixing the top of the adjusting tube 10. The top of the adjusting tube 10 receives the electrical signal transmitted by the lighting control system, and the bottom of the adjusting tube 10 conveys the electrical signal to the LED display board 16, so that the image of the LED display board 16 changes, improving the ornamental value.

[0042] The implementation principle of an LED display device according to an embodiment of the present application is as follows: When installing this device, personnel first screw-fix the fixing gasket 14 at the connection point of the connecting frame 1 and the fixing cross beam 2, and then screw-fix the mounting seat 15 on the indoor top, so that the connecting rod 4 drives the fixing cross beam 2 and the fixing longitudinal beam 3 to be fixedly connected with the connecting frame 1, forming the overall fixation of the connecting frame 1 and the main frame 5.

[0043] Then, an electrical signal is sent through a microcomputer to control the power transmission system to transmit power into the LDE display lamp, so that the LDE display lamp emits light. During the illumination of the LDE display lamp, the display frame 9 surrounds and wraps the LDE display lamp, so that the entire LED display panel 16 irradiates vertically downward with the opening at the bottom of the display frame 9, improving the light brightness. At the same time, during the irradiation of the LED display panel 16, multiple side plates 6 and the bottom plate 7 surround the main frame 5 to form a semi-sealed state, effectively preventing static electricity generated by the power transmission system from adsorbing indoor dust, thereby damaging the power transmission system.

[0044] At the same time, the personnel send an electrical signal through the microcomputer to control the lighting control system. The lighting control system sends an adjustment signal to be conveyed into the LED display panel 16 by the adjusting tube 10, thereby changing the image style displayed on the LED display panel 16 and forming color and image transformations to improve the ornamental value.

[0045] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
