Description

Technical Field

[0001] This utility model relates to the field of LED displays, specifically an LED display with adjustable pixel pitch. Background Technology

[0002] LED mesh screens are creative LED displays consisting of interconnected LED dots forming a mesh structure. They are a type of product designed for brightening and displaying video, satisfying both decorative lighting needs and the ability to play text, images, and videos. They feature a "large pitch" concept, with a dot pitch between 35mm and 200mm, and are typically used in ultra-large area displays exceeding 500m² and in creative display applications.

[0003] According to publicly available patent CN222421262U, an adjustable pixel pitch LED display screen includes multiple guide rails, multiple LED pixels, and a locking mechanism. The guide rails are arranged along a predetermined direction at a set spacing. Each guide rail has a guide groove containing a circuit, and a baffle plate is provided on the inner wall of the guide groove. Each LED pixel includes a carrier and an LED light. The carrier also has a conductive contact electrically connected to the LED light. The carrier is slidably disposed on the guide rail, and the conductive contact is in contact with the circuit. The locking mechanism includes a connecting post with a first limiting block and a second limiting block. One of the first and second limiting blocks is fixed to the connecting post, and the other is threaded to the connecting post. The baffle plate and the carrier are clamped between the first and second limiting blocks. The locking mechanism enables the LED pixels to be adjusted and fixed at any position on the guide rails, achieving a variable pixel pitch for the LED display screen.

[0004] However, in practice, traditional adjustable pixel pitch LED displays use locking mechanisms to achieve arbitrary adjustment of LED pixels. This method requires workers to disassemble and reassemble the LED pixels each time adjustment is needed. This is particularly problematic in large applications like glass curtain walls, where the large area of ​​the curtain wall and the correspondingly large size of the LED display make each pixel disassembly and reassembly not only costly but also extremely labor-intensive. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an LED display screen with adjustable pixel pitch. This solves the problem that the locking mechanism used in current traditional LED displays with adjustable pixel pitch is used to achieve arbitrary adjustment of LED pixels. However, this method of adjusting LED pixels through a locking mechanism requires workers to disassemble and reassemble the LED pixels every time they need to adjust them. This is especially problematic in large-scale applications such as glass curtain walls, where the curtain wall area is large and the corresponding LED display screen is also large. As a result, each disassembly and reassembly of LED pixels is not only costly but also extremely labor-intensive.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design an LED display screen with adjustable pixel pitch, including a glass curtain wall, multiple tracks are installed on the surface of the glass curtain wall, and grooves are provided at both the upper and lower ends of the multiple tracks. One end of the plug-in block is inserted into the groove, and a carrier shell is fixed to the other end of the plug-in block. LED pixels are installed on the surface of the carrier shell, and adjustment components are provided on the side of the track.

[0007] Preferably, the adjusting component includes a circular groove, which is formed on the side of the track. One end of a threaded rod extends into the circular groove, and a bearing is rotatably connected to the end of the threaded rod located in the circular groove. The bearing is installed at one end inside the circular groove.

[0008] Preferably, an electromagnetic ring is sleeved on the outside of the threaded rod, and a threaded sleeve is installed on the inner wall of the electromagnetic ring, with the threaded sleeve being threadedly connected to the threaded rod.

[0009] Preferably, one end of the threaded rod extending into the circular groove is connected to a drive motor, which is mounted on the side of the track.

[0010] Preferably, conductive contact pieces are installed at both the upper and lower ends of the rear surface of the carrier shell, and the conductive contact pieces make contact with the wiring on the surface of the glass curtain wall to conduct electricity.

[0011] Preferably, both ends of the plug block are provided with square slots, a fixed cylinder is installed at one end of the square slot, a movable rod passes through the fixed cylinder, a movable plate is fixed at one end of the movable rod inside the fixed cylinder, and a spring is fixed at one end of the movable plate.

[0012] Preferably, a concave plate is fixed to one end of the movable rod extending out of the fixed cylinder, a fixed rod is fixed inside the concave plate, and a rotating wheel passes through the outside of the fixed rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model combines a track, a threaded rod, and an electromagnetic ring. The rotation of the threaded rod drives the electromagnetic ring to move to the desired pixel position. The electromagnetic ring is then activated, using its magnetic force to attract the housing containing the fixed pixel. During this attraction, the position of the electromagnetic ring is further adjusted. Because the housing is attracted by the electromagnetic ring's magnetic force, it moves accordingly, directly moving the pixels on the housing. This method allows for convenient and efficient adjustment of the spacing between multiple pixels, significantly reducing the tedious and labor-intensive manual adjustment of pixel spacing on glass curtain walls. It solves the problem of traditional adjustable pixel spacing LED displays using locking mechanisms to achieve arbitrary pixel adjustment. However, this method requires disassembling and reassembling the LED pixels each time adjustment is needed. This is particularly problematic in large applications like glass curtain walls, where the large area of ​​the curtain wall and the correspondingly large size of the LED display result in high costs and an enormous workload for each pixel disassembly and reassembly.

[0015] 2. This utility model combines a carrier shell, a fixed cylinder, and a rotating wheel. After the plug-in block on the carrier shell is inserted into the groove, the spring force inside the fixed cylinder will drive the rotating wheel to press against the inner wall of the groove, automatically positioning the carrier shell and the pixel. Moreover, due to the influence of the spring force, the rotating wheel can move under a certain force of traction, and can also cooperate with the attraction of the electromagnetic converter to make the rotating wheel drive the carrier shell and the pixel to move.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: An LED display screen with adjustable pixel pitch, see [link to example]. Figures 1 to 4 The system includes a glass curtain wall 1, on which multiple tracks 2 are installed. Each track 2 has a groove 201 at both ends. One end of a plug-in block 213 is inserted into the groove 201, and the other end of the plug-in block 213 is fixed with a carrier shell 202. LED pixels 203 are installed on the surface of the carrier shell 202. An adjustment component is provided on the side of the track 2. First, the plug-in blocks 213 on the multiple carriers are inserted into the grooves 201 at the upper and lower positions of the track 2 to complete the installation of multiple carrier shells 202 with pixels 203 on the track 2. During the use of the display screen, when it is necessary to adjust the distance between the carrier shell 202 and the pixels 203, the drive motor 3 is started. After the drive motor 3 starts running, it will drive the threaded rod 302 connected to it to rotate. As the threaded rod 302 rotates, the threaded engagement between the threaded rod 302 and the threaded sleeve causes the electromagnetic ring 303 to move along the threaded rod 302, reaching the position of the corresponding pixel 203 that needs adjustment. Then, the electromagnetic ring 303 is activated; when energized, it generates a magnetic force. This magnetic force attracts the carrier shell 202 that holds the pixel 203. During this attraction, the operator can further adjust the position of the electromagnetic ring 303. Because the carrier shell 202 is attracted by the magnetic force of the electromagnetic ring 303, it moves along with the change in the ring's position, directly causing the pixel 203 on the carrier shell 202 to move as well. This method allows for convenient and efficient adjustment of the spacing between multiple pixels 203, avoiding the tedious and labor-intensive manual adjustment of pixel spacing on the glass curtain wall 1. It improves adjustment efficiency and operational convenience, solving the problems associated with traditional adjustable... The LED display screen with a pixel pitch of 203 uses a locking mechanism to enable arbitrary adjustment of the LED pixels 203. However, this method of adjusting the LED pixels 203 through the locking mechanism requires the staff to disassemble and reassemble the LED pixels 203 each time adjustment is needed. This is especially problematic in large-scale applications such as glass curtain walls, where the curtain wall area is large and the corresponding LED display screen is also large. As a result, each disassembly and reassembly of the LED pixels 203 is not only costly but also involves an extremely large workload.

[0023] For details, see Figure 2The adjustment component includes a circular groove 301, which is opened on the side of the track 2. One end of a threaded rod 302 extends into the circular groove 301. A bearing is rotatably connected to one end of the threaded rod 302 located in the circular groove 301. The bearing is installed inside one end of the circular groove 301.

[0024] Further, see Figure 2 An electromagnetic ring 303 is sleeved on the outside of the threaded rod 302. A threaded sleeve is installed on the inner wall of the electromagnetic ring 303, and the threaded sleeve is threadedly connected to the threaded rod 302.

[0025] It is worth noting that, see Figure 2 One end of the threaded rod 302 extending out of the circular groove 301 is connected to a drive motor 3, which is mounted on the side of the track 2.

[0026] It is worth noting that, see Figure 3 Conductive contact pieces 204 are installed at both the upper and lower ends of the rear surface of the housing 202. The conductive contact pieces 204 make contact with the wiring on the surface of the glass curtain wall 1 to conduct electricity.

[0027] It is worth mentioning that, see Figure 4 Both ends of the plug-in block 213 are provided with square slots 205. A fixed cylinder 209 is installed at one end of the square slot 205. A movable rod 212 passes through the fixed cylinder 209. A movable plate 211 is fixed at one end of the movable rod 212 inside the fixed cylinder 209. A spring 210 is fixed at one end of the movable plate 211. During the installation of the carrier shell 202 and the pixel 203, the plug-in block 213 on the carrier shell 202 is first inserted into the corresponding groove 201. After insertion, the spring 210 inside the fixed cylinder 209 will use its elastic force to drive the movable plate 211 and the connected movable rod 212 to move. The movement of the movable rod 212 further drives the movement of the concave plate 207, which in turn pushes the rotating wheel 206 to press tightly against the inner wall of the groove 201, thus realizing the movement of the carrier shell. The automatic positioning of the housing 202 and its pixels 203 ensures the stable installation of the housing 202 on the track 2. Due to the elasticity of the spring 210, the rotating wheel 206 is not completely fixed, but can move flexibly under a certain force. When the electromagnetic ring 303 is activated and generates a magnetic force to attract the housing 202, the rotating wheel 206 can cooperate with the magnetic force of the electromagnetic ring 303. When the electromagnetic ring 303 attracts the housing 202, the rotating wheel 206 will drive the housing 202 and its pixels 203 to move together under the combined action of the elasticity of the spring 210 and the magnetic force of the electromagnetic ring 303. In this way, the position of the housing 202 and the pixels 203 can be flexibly adjusted, thereby conveniently adjusting the spacing of the pixels 203 and meeting the adjustment needs of the pixel spacing of the LED display in different scenarios.

[0028] It is worth emphasizing that, see Figure 4 One end of the movable rod 212 extending out of the fixed cylinder 209 is fixed with a concave plate 207. A fixed rod 208 is fixed inside the concave plate 207, and a rotating wheel 206 passes through the outside of the fixed rod 208.

[0029] When using an LED display with adjustable pixel pitch 203, firstly, the insertion blocks 213 on multiple carriers are inserted into the grooves 201 at the upper and lower positions of the track 2. This completes the installation of multiple carrier shells 202 with pixel pitch 203 on the track 2. During the use of the display, when it is necessary to adjust the pitch between the carrier shell 202 and the pixel pitch 203, the drive motor 3 is started. After the drive motor 3 starts running, it will drive the threaded rod 302 connected to it to rotate. As the threaded rod 302 rotates, the threaded engagement between the threaded rod 302 and the threaded sleeve will drive the electromagnetic ring 303 to move along the threaded rod 302, so that it reaches the position of the corresponding pixel pitch 203 that needs to be adjusted. Then, the electromagnetic ring 303 is activated. After the electromagnetic ring 303 is energized, it will generate a magnetic force. Through this magnetic force, the electromagnetic ring 303 can attract the carrier shell 202 that fixes the pixel pitch 203. During the process of the electromagnetic ring 303 attracting the carrier shell 202, the operator further adjusts the position of the electromagnetic ring 303. Due to the magnetic attraction of the electromagnetic ring 303, the carrier shell 202 moves with the change in the position of the electromagnetic ring 303, thereby directly driving the pixel points 203 on the carrier shell 202 to move together. In this way, the spacing of multiple pixel points 203 can be adjusted conveniently and efficiently, avoiding the tedious operation and huge workload of manually adjusting the spacing of pixel points 203 on the glass curtain wall 1, improving the adjustment efficiency and the convenience of operation. During the installation of the carrier shell 202 and pixel points 203, the plug block 213 on the carrier shell 202 is first inserted into the corresponding groove 201. After insertion, the spring 210 in the fixed cylinder 209 will use its elastic force to drive the moving plate 211 and the connected moving rod 212 to move. The movement of the moving rod 212 further drives the concave plate 207. The concave plate 207 pushes the rotating wheel 206 to press tightly against the inner wall of the groove 201, realizing the automatic positioning of the carrier shell 202 and the pixels 203 thereon, ensuring the stable installation of the carrier shell 202 on the track 2. Due to the elasticity of the spring 210, the rotating wheel 206 is not completely fixed, but can move flexibly under a certain force. When the electromagnetic ring 303 is activated and generates a magnetic force to attract the carrier shell 202, the rotating wheel 206 can cooperate with the magnetic force of the electromagnetic ring 303. When the electromagnetic ring 303 attracts the carrier shell 202, the rotating wheel 206 will drive the carrier shell 202 and the pixels 203 thereon to move together under the combined action of the elasticity of the spring 210 and the magnetic force of the electromagnetic ring 303. In this way, the position of the carrier shell 202 and the pixels 203 can be flexibly adjusted, thereby conveniently adjusting the spacing of the pixels 203 and meeting the adjustment needs of the pixel spacing of the LED display screen in different scenarios.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
