Description

Technical Field

[0001] The utility model belongs to the technical field of display screen installation, and particularly relates to an installation structure of a LED display screen, LED display screen equipment and a bus shelter. Background Art

[0002] Public transportation is an environmentally friendly and green travel mode advocated by the country, and is an important mode of transportation for urban residents in my country. The bus shelters at bus stops are relatively important infrastructure for the convenience of the people, and are also an important means of urban lighting and cultural information dissemination. They are composed of foundations, columns, ceilings, benches, route signs, advertising media light boxes (referred to as advertising light boxes in the industry), electronic bus stops, etc.

[0003] With the development of science and technology and the increasing demand for efficient information acquisition, more and more intelligent and real-time updated outdoor display products are embedded in bus shelters. Among them, LED display products are increasingly used in bus shelters due to their low power consumption, clear color rendering, low cost and long life, and are showing a trend of replacing LCD screen products.

[0004] However, LED display screens usually require multiple LED unit boards to be spliced ​​together, and have high requirements for mounting quality including seams and flatness. The installation process is more complicated and tedious than LCD screen products. A set of LED display screens embedded in large advertising light boxes usually requires dozens or even hundreds of LED unit boards, and the installation workload is relatively large.

[0005] At present, the LED display screens embedded in the advertising light boxes of bus shelters are mostly installed using the installation structure of the outdoor advertising field, that is, criss-cross welded pipe racks or sheet metal C-shaped bends are used as the structural support skeleton, and then the LED unit boards are fixed on it by magnetic attraction or bolt fastening. During the splicing process, each unit board needs to be constantly adjusted to ensure that the joints between the two are tightly fitted.

[0006] like Figure 1 As shown in the figure, the general structure of embedded LED display products used in bus shelters on the market is:

[0007] It includes an advertising light box sheet metal box body 1, and a relatively independent structural support frame 2 is arranged on the advertising light box sheet metal box body 1. The structural support frame 2 is mainly made of pipes that are cut and arranged in a criss-cross pattern and welded into one body, and then fixed in the advertising light box sheet metal box body 1 by welding or bolting. There is also a situation that some manufacturers will use sheet metal bending to replace pipes according to different production processes, and combine them into a structural support frame 2 by welding, riveting or bolting. The LED unit board 3 is spliced ​​and fixed on the structural support frame 2, and the LED unit board 3 is fixed by magnetic attraction through a strong magnet, or fixed by bolting.

[0008] The embedded LED display installation structure in the prior art has the following shortcomings:

[0009] 1. The length of advertising light boxes on the market is mostly more than 3 meters and the height is more than 1.5 meters. The entire structural support frame 2 is relatively large. Whether it is pre-fixed in the advertising light box sheet metal box 1 or fixed in the advertising light box sheet metal box 1 after assembling the LED unit board 3, it is not convenient to install and consumes a lot of manpower.

[0010] 2. This structural form has certain disadvantages regardless of whether it adopts "magnetic fixation" or "bolt fixation". First, since there are not only 4 fixing holes on the back of each LED unit board 3, taking the unit board of 320×160mm as an example, there are 10 or even more fixing holes on the back, and this structural form cannot fix all the fixing holes of the LED unit board, and thus the overall assembly flatness cannot be guaranteed, and the flatness of the structural support frame 2 will further affect the assembly flatness of the LED display screen; secondly, the transportation and installation of bus shelter products are different from the on-site installation method of the large-scale outdoor advertising industry. Basically, the installation method adopts the pre-installation of various components in the factory, the assembly of various components on-site, and the overall foundation fixation. The on-site installation time is generally about three hours. If "magnetic fixation" is adopted, the vibration and bumping of the bus shelter advertising light box during transportation will cause the displacement of some LED unit boards, and secondary adjustments are required after on-site installation, which wastes manpower. If the "magnetic fixation" method is used for on-site mounting, firstly, it is inconvenient to mount due to the complex construction environment of the city's main roads on site. Secondly, the time to install a bus shelter will be one day or more longer, and the production cost will increase. If the "bolt fixation" method is used for mounting, although it can avoid transportation vibration and displacement to a certain extent, the structural support skeleton 2 cannot fix all the fixing holes of each LED unit board 3, which will cause uneven force on the fixed position of a single LED unit board 3. In addition, the structural support skeleton 2 also has a certain flatness production deviation. As a result, it is easy to cause local slight warping and deformation of the LED unit board. During the overall assembly, it is difficult to control the flatness of the LED screen, and it is also time-consuming and labor-intensive to adjust.

[0011] 3. The existing structural form occupies a large space when mounting the LED unit board 3, the mounting workload is large, and the mounting time is long. It is impossible to form a "production line" type of production and assembly, and the production efficiency is low. Utility Model Content

[0012] The main technical problem solved by the utility model is to provide an installation structure of an LED display screen which can improve assembly efficiency, ensure the flatness of the display screen after assembly, and ensure assembly quality, and at the same time provide an LED display screen device and a bus shelter using the installation structure.

[0013] In order to solve the above technical problems, the first technical solution adopted by the utility model is:

[0015] Furthermore, a plurality of the LED splicing screen modules are arranged horizontally and / or vertically to form a complete LED display screen, and at least the top row of the LED splicing screen modules are fixed to the supporting frame via a suspension mechanism.

[0016] Furthermore, the hanging mechanism includes a hanging rod assembly installed on the supporting frame and a hook assembly correspondingly installed on the top of the LED splicing screen module.

[0018] Furthermore, an opening is provided on the installation plane plate within each installation partition, and positioning pin holes for positioning the LED unit plate, fixing holes fixedly connected to the LED unit plate, and a connecting structure fixedly connected to the supporting frame are provided on the installation plane plate around the opening.

[0019] Furthermore, the connection structure includes a rivet nut preassembled on the first outer frame of the mounting plate assembly and fixedly connected to the supporting frame by bolts.

[0020] Furthermore, the support skeleton includes a second outer frame, in which a plurality of second transverse ribs and second longitudinal ribs are arranged, and a plurality of oblong mounting holes are arranged on the second longitudinal ribs, which are fixedly connected to the LED splicing screen module by bolts.

[0021] Furthermore, a horizontal limiting plane is provided on the bottom edge of the supporting frame, and after installation, the bottom of the LED splicing screen module abuts against the horizontal limiting plane.

[0022] The second technical solution adopted by the utility model is:

[0023] An LED display screen device comprises a box body, on which an LED display screen is mounted. The LED display screen is mounted on the box body by means of the LED display screen mounting structure as described above.

[0024] The third technical solution adopted by the utility model is:

[0025] A bus shelter is provided with the LED display screen device as described above.

[0026] In summary, the LED display installation structure, LED display device and bus shelter provided by the utility model have the following advantages compared with the prior art:

[0027] (1) This structure realizes the modular assembly of LED display screens. A large LED display screen is divided into multiple modules with relatively small areas. Each module is pre-assembled in the factory and then assembled on site to form a complete LED display screen. This is not only conducive to ensuring the mounting flatness of the LED display screen after assembly, but also occupies relatively little space in the mounting process in the factory, which can realize "assembly line" type production. It is also simple and convenient to assemble on site, which fully improves the mounting and assembly efficiency and solves the problem in the prior art that LED display screen equipment such as large advertising light boxes used in bus shelters are inconvenient to install on site, difficult to form assembly line operations, and have low operating efficiency.

[0028] (2) This structure installs each LED splicing screen module in the top row on the supporting frame by hanging, which can greatly save manpower during on-site assembly, save labor, improve assembly efficiency and reduce assembly costs.

[0029] (3) This structure is conducive to ensuring the flatness of the installation plane of the LED display screen, and can achieve seamless splicing between each LED splicing screen module, thereby improving the assembly quality and solving the problem of insufficient mounting flatness of LED unit boards in LED display screen equipment such as large advertising light boxes used in bus shelters in the prior art.

[0030] (4) The structure connects the LED unit board and the mounting plate group by bolts, which helps to ensure that the LED unit board and the mounting plate group are firmly fixed and will not loosen during transportation and installation, thereby affecting the assembly accuracy and quality. This solves the problem in the prior art that LED display screen equipment such as large advertising light boxes used in bus shelters may be misaligned and have splicing gaps due to vibration and bumps during transportation, requiring secondary adjustments on site.

[0031] (5) This structure is highly versatile and has no restrictions on the size of the LED display screen, the specifications of the LED unit board, the size, quantity, arrangement of the modules, the number of longitudinal and transverse ribs of the supporting frame, etc.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] Embodiment 1:

[0051] like Figure 2 and Figure 3 As shown, the utility model provides a mounting structure for an LED display screen, which can be used on any device that needs to install an embedded LED display screen, such as an advertising media light box, an electronic bus stop sign, etc. installed in a bus shelter or other outdoor places.

[0052] In this embodiment, the installation structure of the LED display screen includes a supporting frame 5 and an LED display screen 6. The supporting frame 5 is fixed on a box body 4 of an advertising light box or other equipment. The LED display screen 6 is composed of multiple LED splicing screen modules 7, and the multiple LED splicing screen modules 7 are respectively fixed on the supporting frame 5.

[0053] In this embodiment, preferably, each LED splicing screen module 7 is composed of a mounting plate group 71 and a plurality of LED unit boards 72 spliced ​​and fixed on the mounting plate group 71, and the plurality of LED unit boards 72 are spliced ​​and fixed on the mounting plate group 71 to form a complete LED splicing screen module 7.

[0054] This structure splits the LED display screen 6 into a plurality of relatively small LED splicing screen modules 7. Each LED splicing screen module 7 can be pre-assembled in a factory and then assembled on site to form a complete LED display screen 6.

[0055] In this embodiment, the number of LED splicing screen modules 7 and the size of each LED splicing screen module 7 can be set according to the area of ​​the LED display screen 6 and conditions such as transportation and on-site installation requirements. Multiple LED splicing screen modules 7 can be arranged horizontally and / or vertically to form a complete LED display screen 6.

[0056] like Figure 2 As shown, this embodiment provides an implementation method, where every two rows of LED unit boards 72 in the horizontal direction form an LED splicing screen module 7. For example, the LED display screen 6 is split into five LED splicing screen modules 7, and the five LED splicing screen modules 7 are arranged side by side in the horizontal direction, and each LED splicing screen module 7 is spliced ​​in a 9×2 arrangement, that is, 18 LED unit boards 72 are installed on a mounting plate group 71 to form an LED splicing screen module 7, and one LED display screen 6 includes a total of 90 LED unit boards 72.

[0057] like Figure 8 As shown, this embodiment provides another implementation method, in which the LED unit boards 72 in every two columns in the horizontal direction are respectively split into upper and lower two LED splicing screen modules 7. For example, if 90 LED unit boards 72 are used to splice an LED display screen 6, the LED display screen 6 can be split into 10 LED splicing screen modules 7, and the upper LED splicing screen modules 7 are spliced ​​in a 3×2 arrangement, and the lower LED splicing screen modules 7 are spliced ​​in a 6×2 arrangement.

[0058] Of course, the splitting and arrangement of the LED splicing screen module 7 is not limited to the two implementation methods provided above. It can be split and arranged arbitrarily according to actual needs. For example, one or three horizontal columns of LED unit boards 72 can be assembled into one module, and one, two or three columns of LED unit boards 72 can be further split into upper, middle and lower modules.

[0059] This structure realizes the modular assembly of the LED display screen 6, splitting a large LED display screen 6 into multiple relatively small LED splicing screen modules 7, which not only improves the mounting flatness of the LED display screen 6, but also occupies relatively little space in the mounting process in the factory, and can realize "assembly line" type production. At the same time, it can also ensure the assembly quality of each LED splicing screen module 7, and it is also simple and convenient for on-site assembly, which can greatly save manpower during assembly, save labor, improve assembly efficiency, and reduce assembly costs.

[0060] like Figure 5 , Figure 6 and Figure 7As shown, in this embodiment, it is further preferred that each mounting plate group 71 includes a first outer frame 711, and a mounting plane plate 715 is mounted in the first outer frame 711. The mounting plane plate 715 and the first outer frame 711 can be welded together, or two sides or four sides of the mounting plane plate 715 can be bent to form the first outer frame 711 as a whole.

[0061] In this embodiment, it is further preferred that a plurality of first transverse ribs 712 and / or first longitudinal ribs 713 are welded and fixed on the installation plane plate 715, and the installation plane plate 715 is divided into a plurality of installation partitions 714 by the first transverse ribs 712 and / or first longitudinal ribs 713, and an LED unit board 72 is fixedly installed in each installation partition 714 to form an LED splicing screen module 7. The first outer frame 711, the first transverse ribs 712, the first longitudinal ribs 713 and the installation plane plate 715 are preferably made of stainless steel to ensure the overall structural strength of the installation plate group 71 and the flatness of the LED unit boards 72 after splicing.

[0062] In this embodiment, it is further preferred that an opening (not shown) is provided on the installation plane plate 715 in each installation partition 714, and the opening is located on the back of the LED unit plate 72. The installation plane plate 715 around the opening is provided with a positioning pin hole 716 for positioning with the LED unit plate 72, a fixing hole 717 fixedly connected with the LED unit plate 72, and a connection structure fixedly connected with the support frame 5. This structure not only facilitates the installation of the LED unit plate 72, but also ensures that there is no gap between adjacent LED unit plates 72 after the LED unit plate 72 is installed, and also ensures the installation quality of the LED unit plate 72, ensures that the force between the LED unit plate 72 and the installation plane plate 715 is uniform, and further ensures the assembly quality.

[0063] According to the size of each LED unit board 72, positioning pin holes 716 are set on the mounting plane plate 715 around the opening. The positioning pins matching the LED unit board 72 are inserted into the positioning pin holes 716 accordingly, so that the LED unit board 72 can be accurately positioned, thereby ensuring that multiple LED unit boards 72 will not flash after installation.

[0064] The LED unit board 72 is fixedly connected to the corresponding fixing holes 717 on the mounting plane board 715 around the opening by multiple bolts, thereby fixing the LED unit board 7 on the mounting plane board 715 in the mounting partition 714. The LED unit board 72 is fixedly connected to the mounting plate group 71 by bolts, which is conducive to ensuring that the LED unit board 72 and the mounting plate group 71 are firmly fixed and will not loosen during transportation and installation, which is conducive to ensuring the flatness of the mounting plane of the LED unit board 72, thereby ensuring the assembly accuracy and assembly quality, and solving the problem of the large advertising light box used for bus shelters in the prior art, which causes the LED unit board to be misaligned and have splicing gaps due to vibration and bumps during transportation, and requires secondary adjustment on site.

[0065] In this embodiment, the support skeleton 5 includes a second outer frame 51, a plurality of second transverse ribs 52 and second longitudinal ribs 53 are arranged in the second outer frame 51, and one or more LED splicing screen modules 7 are installed between every two adjacent second longitudinal ribs 53. The two sides of the LED splicing screen module 7 are fixedly connected to the support skeleton 5. The second outer frame 51, the second transverse ribs 52 and the second longitudinal ribs 53 are all made of stainless steel and connected together by welding to ensure the overall structural strength of the support skeleton 5. The second outer frame 51 is welded to the box body 4 of the device, and can also be integrated with the box body 4.

[0066] In this embodiment, a plurality of oblong mounting holes 54 are provided on the second longitudinal rib 53, and the oblong mounting holes 54 extend in the horizontal direction. The oblong mounting holes 54 are arranged in parallel from top to bottom. Appropriate oblong mounting holes 54 can be selected according to the size and installation position of the LED splicing screen module 7, and the oblong mounting holes 54 are fixedly connected to the mounting plate group 71 by bolts. This is conducive to facilitating the on-site assembly, and fine-tuning the relative position relationship between the LED splicing screen module 7 and the supporting frame 5 to the left and right, thereby ensuring the flatness of the entire LED display screen 6 after installation, and fully ensuring that there will be no gaps between the LED splicing screen modules 7, thereby ensuring the assembly quality.

[0067] In this embodiment, it is further preferred that the connection structure connected to the support frame 5 provided on the mounting plate group 71 includes rivet nuts 718 preassembled on the first outer frame 711 of the mounting plate group 71. Specifically, the cross-section of the first outer frame 711 on both sides of the mounting plate group 71 is a C-shaped structure, having a bent edge 719 facing the support frame 5, and the rivet nuts 718 are preassembled on the bent edge 719. The rivet nuts 718 on the bent edges 719 on both sides of the first outer frame 711 are fixedly connected with the oblong mounting holes 54 on the second longitudinal ribs 53 on both sides of the mounting plate group 71 by bolts, which is convenient for installation and can ensure firm installation.

[0068] Due to the modular installation, the number of the second transverse ribs 52 and the second longitudinal ribs 53 of the support frame 2 can be greatly reduced compared with the prior art, which can greatly reduce the impact of the support frame 2 on the overall flatness of the LED display screen 6 when it is deformed, saving time and effort during on-site assembly.

[0069] For equipment equipped with an embedded LED display, in order to protect the display, a front door and / or a rear door are generally installed on the equipment box 4, and the front door and the rear door mostly adopt an upward opening structure with a limited opening angle of about 37°. The installation space becomes smaller as it goes up. When the top of the LED display needs to be fixed to the supporting frame 5 by screws, the operating space is extremely small, and the installation is time-consuming and labor-intensive.

[0070] In this embodiment, preferably, at least the top row of LED splicing screen modules 7 is fixed to the support frame 5 through a suspension mechanism 8. Figure 2 In the embodiment shown, a suspension mechanism 8 is provided on the top of each LED splicing screen module 7, and each LED splicing screen module 7 is also fixedly connected to the support frame 5 by bolts. Figure 8 In the illustrated embodiment, a suspension mechanism 8 is provided on the top of the upper row of LED splicing screen modules 7 and is fixedly connected to the support frame 5 by bolts, while a suspension mechanism 8 is not provided on the lower row of LED splicing screen modules 7 but is only fixedly connected to the support frame 5 by bolts.

[0071] This structure installs the upper LED splicing screen module 7 on the supporting frame 5 by hanging, which not only facilitates the positioning and connection of the upper LED splicing screen module 7 and the supporting frame 5, but also facilitates the upper LED splicing screen module 7 to fine-tune the gap between modules to ensure seamless splicing, which can greatly save manpower during assembly, save labor, improve assembly efficiency and reduce assembly costs.

[0072] like Figure 4 and Figure 6 As shown, in this embodiment, preferably, the suspension mechanism 8 is arranged on the top of the upper LED splicing screen module 7, and the suspension mechanism 8 includes a hanging rod assembly 81 installed on the support frame 5 and a hook assembly 82 installed on the top of the mounting plate group 71. Each upper LED splicing screen module 7 is installed by one or two sets of hanging rod assemblies 81 and hook assemblies 82.

[0073] The hanging rod assembly 81 includes a U-shaped hanging plate 811, and a horizontal hanging rod 812 is installed between two side plates of the hanging plate 811. The bottom of the hanging plate 811 is welded to the top of the support frame 5. Of course, two parallel hanging plates (not shown in the figure) can also be directly welded to the support frame 5, and a horizontal hanging rod is installed between the two hanging plates.

[0074] The hook assembly 82 includes a U-shaped base 821, which is welded and fixed to the top of the first outer frame 711 of the mounting plate assembly 71, and the parallel side plates on both sides of the U-shaped base 821 are each provided with a concave structure to form two hooks 822. During installation, it is only necessary to hang the two hooks 822 on one hanging rod 812 at the same time, which is simple and convenient to install, saving time and effort.

[0075] In order to ensure the overall flatness of multiple LED splicing screen modules 7 when they are assembled on site, it is further preferred in this embodiment that a horizontal limit plane 9 that meets the horizontal standard is provided on the bottom edge of the second outer frame 51 of the support frame 5. The horizontal limit plane 9 extends in the horizontal direction and can be continuous or disconnected. After installation, the bottom of the mounting plate group 71 abuts against the horizontal limit plane 9 to ensure that each LED splicing screen module 7 is on the same horizontal plane after installation, that is, the flatness of each LED splicing screen module 7 after installation can be ensured.

[0076] In the factory, multiple LED unit boards 72 are first fixedly installed in multiple installation partitions 714 on a mounting plate group 71 by bolts to form a complete LED splicing screen module 7. Then, multiple LED splicing screen modules 7 are transported to the assembly site, and the top row of LED splicing screen modules 7 are fixedly connected to the support frame 5 through the suspension mechanism 8 and the rivet nut 718, and the multiple LED splicing screen modules 7 below are fixedly connected to the support frame 5 through the rivet nut 718, thereby completing the overall assembly of the LED display screen 6.

[0077] The installation structure of the embedded LED display screen provided in this embodiment has the following advantages:

[0078] 1. This structure realizes the modular assembly of the LED display screen 6, which is not only conducive to ensuring the mounting flatness of the LED display screen 6 after assembly, but also occupies relatively little space in the mounting process in the factory, and can realize "assembly line" type production.

[0079] 2. This structure installs the top row of LED splicing screen modules 7 on the supporting frame 5 by hanging, which not only facilitates the positioning and connection of the upper LED splicing screen modules 7 and the supporting frame 5, but also facilitates the upper LED splicing screen modules 7 to fine-tune the gap between the modules to ensure seamless splicing, which can greatly save manpower during assembly, save labor, improve assembly efficiency and reduce assembly costs.
