Description

Technical Field

[0001] This utility model relates to the field of road traffic sign equipment technology, and in particular to an assembly display screen structure. Background Technology

[0002] Variable message signs, also known as variable information boards, are large display devices assembled from modular screen modules. They are versatile and interchangeable, easy to maintain, have uniform brightness, stable performance, and are energy-efficient and environmentally friendly. Variable message signs are an important way for highway management departments to provide travelers with real-time traffic information, playing a vital role in traffic management, alleviating highway congestion, and ensuring traffic safety.

[0003] In the prior art, Chinese patent (CN210443175U) discloses a display cabinet, an LED display screen, and an LED display screen assembly structure; and Chinese patent (CN216980051U) discloses an LED display screen that can be quickly assembled into a large display screen. The existing display screen structures have the following drawbacks: 1. The assembly structure design is not reasonable enough, making it inconvenient to complete assembly quickly; 2. The installation structure design is not reasonable enough, making installation and use inconvenient and the installation not stable or reliable; 3. The overall structural strength is poor.

[0004] Therefore, how to design a modular display screen structure that is simpler and more reasonable in design, easier to assemble, more stable and reliable in installation, and has higher structural strength has become a technical problem to be solved. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to design a modular display screen structure that is simpler and more reasonable in structure, easier to assemble, more stable and reliable in installation, and has higher structural strength.

[0006] To achieve the above objectives, this utility model provides a modular display screen structure, comprising two or more display screen units arranged horizontally in a row, each display screen unit including display unit modules arranged horizontally in a row and vertically in a column on the front side; the display screen unit also includes a support frame with an overall rectangular structure design on the rear side; the support frame includes frame vertical plates on both sides in the horizontal direction, and adjacent frame vertical plates on adjacent display screen units are spliced ​​together by a modular structure; the modular structure is characterized in that; the modular structure includes a plurality of splicing protrusions arranged vertically at intervals on the outer edge of the frame vertical plates and integrally formed and protruding rearward, such that two opposite splicing protrusions on two adjacent frame vertical plates are connected together by bolts; mounting protrusions are also integrally formed at both ends of the frame vertical plates and protruding rearward, such that two opposite mounting protrusions on two adjacent frame vertical plates are provided with a pair of mounting holes.

[0007] Thus, in the above-described modular display screen structure, the splicing structure design between two adjacent display screen units is simpler and more reasonable, making it easier to assemble and disassemble the display screen units. Secondly, the designed installation structure is simpler and more reasonable, and also improves the stability and reliability of the installation.

[0008] Furthermore, the opposing surfaces of the two mounting protrusions are provided with mating grooves and mating protrusions that cooperate with each other.

[0009] This makes it easier to align the two display screen units during assembly.

[0010] Furthermore, the projection of the mounting protrusion onto the surface of the frame vertical plate is designed in an L-shape.

[0011] As an optimization, the splicing protrusions on the outer edge of the frame vertical plate are arranged in pairs vertically; the middle of the vertical end faces of the splicing protrusions each extend outward to form a reinforcing strip, and the far ends of the reinforcing strips are bent inward and extended, so that the inner side of the reinforcing strips are connected to the surface of the frame vertical plate.

[0012] This design allows for a more rational number of splicing bumps. It also improves the structural strength of the splicing bumps, resulting in a more stable and reliable assembled structure.

[0013] As an optimization, the support frame also includes frame horizontal plates at both vertical ends. The surface of the frame horizontal plates and the rear surface of the frame vertical plates partially protrude backward to form horizontal and vertical enclosure plates, and the two horizontal and two vertical enclosure plates are connected in a rectangular structure design. Multiple vertically spaced connecting plates are arranged between the two frame vertical plates, and the connecting plates, horizontal and vertical enclosure plates form an installation cavity. Electrical components are arranged in the installation cavity, and a rear cover is provided corresponding to the opening of the installation cavity.

[0014] This makes the structural design of the support frame simpler and more reasonable. Furthermore, by designing horizontal and vertical partitions and connecting plates to form mounting cavities, it is easier to arrange the electrical components.

[0015] Furthermore, the electrical components include a fan, a power supply mounting plate, and terminal blocks.

[0016] Furthermore, the connecting plate and the frame vertical plate are integrally formed, and the connecting plate consists of three vertically spaced plates.

[0017] As an optimization, a downward-deepening mounting cavity is provided at the center of the upper horizontal panel. Each side wall of the mounting cavity has an inwardly extending mounting strip. A mounting block is provided above the outer end of each mounting strip. A connecting screw protrudes downward from the center of the lower end face of the mounting block and passes through a through hole at the outer end of the mounting strip. A nut is provided at the lower end of the connecting screw. Each mounting block has a mounting notch at its upper end. A U-shaped handle is provided corresponding to each mounting block. Both ends of the handle extend into the mounting notch, and each end of the handle has a hinge shaft, allowing the two ends of the hinge shaft to be inserted into the hinge holes on the side walls of the mounting notch.

[0018] In this way, by installing not only handles, the display unit can be moved more easily, and the arrangement of the handles is simpler and more reasonable.

[0019] As an optimization, the support frame is made of aluminum alloy.

[0020] This gives the entire display unit better structural strength and also better meets the requirements of lightweight design.

[0021] As an optimization, a mounting bracket made of plastic with a grid structure is provided on the front side of the support frame, and the display unit module is mounted on the mounting bracket.

[0022] In this way, by designing the mounting bracket, it becomes easier to install and arrange the display unit modules.

[0023] As an optimization, the display unit module is arranged in two rows horizontally and four columns vertically.

[0024] In this way, the number and arrangement of display unit modules are more reasonable.

[0025] In summary, the above-mentioned modular display screen structure features a simpler and more reasonable structural design, easier assembly, more stable and reliable installation, and higher structural strength. Attached Figure Description

[0034] like Figures 1 to 7 As shown, a modular display screen structure includes two or more display screen units 1 arranged horizontally in a row. Each display screen unit includes display unit modules 2 arranged horizontally in a row and vertically in a column on the front side. The display screen unit also includes a support frame 3 with an overall rectangular structure design on the rear side. The support frame includes frame vertical plates 4 on both sides in the horizontal direction, and adjacent frame vertical plates on adjacent display screen units are spliced ​​together by a modular structure. The modular structure includes a plurality of splicing protrusions 5 arranged vertically at intervals on the outer edge of the frame vertical plates and integrally formed and protruding backward, such that two opposite splicing protrusions on adjacent frame vertical plates are connected together by bolts. Mounting protrusions 6 are also integrally formed and protruding backward at both ends of the frame vertical plates, and two opposite mounting protrusions on adjacent frame vertical plates are provided with a pair of mounting holes 7.

[0035] Thus, in the above-described modular display screen structure, the splicing structure design between two adjacent display screen units is simpler and more reasonable, making it easier to assemble and disassemble the display screen units. Secondly, the designed installation structure is simpler and more reasonable, and also improves the stability and reliability of the installation.

[0036] Furthermore, the opposing surfaces of the two mounting protrusions are provided with mating grooves 8 and mating protrusions 9 that cooperate with each other.

[0037] This makes it easier to align the two display screen units during assembly.

[0038] Furthermore, the projection of the mounting protrusion onto the surface of the frame vertical plate is designed in an L-shape.

[0039] In this specific embodiment, the splicing protrusions on the outer edge of the frame vertical plate are two vertically paired protrusions; the middle of the vertical end faces of the splicing protrusions each extend outward to form a reinforcing strip 10, and the far ends of the reinforcing strips are bent inward and extended, so that the inner side of the reinforcing strips are connected to the surface of the frame vertical plate.

[0040] This design allows for a more rational number of splicing bumps. It also improves the structural strength of the splicing bumps, resulting in a more stable and reliable assembled structure.

[0041] In this specific embodiment, the support frame also includes frame horizontal plates 11 at both vertical ends. The surface of the frame horizontal plates and the rear surface of the frame vertical plates partially protrude backward to form a horizontal enclosure plate 12 and a vertical enclosure plate 13, and the two horizontal enclosure plates and the two vertical enclosure plates are connected in a rectangular structure design. Multiple vertically spaced connecting plates 14 are arranged between the two frame vertical plates, and an installation cavity 15 is formed between the connecting plates, the horizontal enclosure plates and the vertical enclosure plates. An electrical component structure is arranged in the installation cavity, and a rear cover 16 is provided corresponding to the opening of the installation cavity.

[0042] This makes the structural design of the support frame simpler and more reasonable. Furthermore, by designing horizontal and vertical partitions and connecting plates to form mounting cavities, it is easier to arrange the electrical components.

[0043] Furthermore, the electrical components include a fan 17, a power supply mounting plate 18, and terminal blocks 19.

[0044] Furthermore, the connecting plate and the frame vertical plate are integrally formed, and the connecting plate consists of three vertically spaced plates.

[0045] In this specific embodiment, a downwardly drawn mounting cavity 20 is provided at the center of the upper surface of the horizontal panel. Mounting strips 21 extending inward are provided on both sides of the mounting cavity. Mounting blocks 22 are provided above the outer ends of the mounting strips. A connecting screw protrudes downward from the center of the lower end face of the mounting block and passes through the through hole at the outer end of the mounting strip. A nut 23 is provided at the lower end of the connecting screw. Mounting notches are provided at the upper ends of the mounting blocks. Handles 24 with U-shaped structures are provided for the two mounting blocks. Both ends of the handles extend into the mounting notches. Hinges are provided at both ends of the handles, so that the two ends of the hinges can be inserted into the hinge holes on the side walls of the mounting notches.

[0046] In this way, by installing not only handles, the display unit can be moved more easily, and the arrangement of the handles is simpler and more reasonable.

[0047] In this specific embodiment, the support frame is made of aluminum alloy.

[0048] This results in better structural strength for the entire display unit and also better meets lightweight design requirements. Furthermore, the support frame is obtained through die casting.

[0049] In this specific embodiment, a mounting bracket 25 made of plastic with a grid structure is provided on the front side of the support frame, and the display unit module is provided on the mounting bracket.

[0050] In this way, by designing the mounting bracket, it becomes easier to install and arrange the display unit modules.

[0051] In this specific embodiment, the display unit module is arranged in two horizontal rows and four vertical columns.

[0052] In this way, the number and arrangement of display unit modules are more reasonable.

[0053] In summary, the above-mentioned modular display screen structure features a simpler and more reasonable structural design, easier assembly, more stable and reliable installation, and higher structural strength.
