Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically to a foldable and splicable transparent display screen. Background Technology

[0002] As a member of the flat panel display family, LCD screens occupy an important position in modern electronic devices, commonly found in television and computer screens. Their advantages are significant: firstly, they have low power consumption, effectively reducing device energy consumption; secondly, they are small and lightweight, providing strong support for the thinner and lighter design of electronic devices; and thirdly, they have low radiation levels, minimizing the impact on user health. The imaging principle of LCD screens is based on a liquid crystal solution between two polarized materials. When an electric current passes through this liquid crystal solution, it causes the crystal particles to rearrange in an orderly manner, thereby achieving the imaging function and presenting a clear picture to the user.

[0003] Traditional displays typically employ a fixed structure, which makes it difficult to make subsequent adjustments once the position is determined during installation. When faced with diverse installation scenarios, such as irregular display spaces or occasions requiring multi-angle displays, fixed-structure displays cannot flexibly change positions, greatly limiting their application range and making it difficult to meet users' adaptability to different display needs. Utility Model Content

[0004] To address the aforementioned technical problems, a foldable and splicable transparent display screen is provided. This technical solution solves the problem of low applicability mentioned in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A foldable and splicable transparent display screen includes: a mounting frame and a substrate. The substrate is fixedly mounted between the outer surfaces of two sets of mounting frames. A plurality of mounting holes are formed in the middle of the outer surface of the substrate. A plurality of holes are formed on both sides of the outer surface of the substrate. A shell is provided at the bottom of the outer surface of the substrate. A plurality of nuts are provided at the ends of the substrate and the shell that are close to each other. The outer surface of the nuts is located at the bottom of the mounting holes. The outer surfaces of the shell and the substrate are mounted by a positioning shaft that passes through the outer surface. The outer surface of the nuts is mounted on the top of the shaft surface of the positioning shaft.

[0007] Preferably, a knob is slidably mounted on the middle of the outer surface of the mounting frame, a first rotating rod is fixedly mounted on the bottom end of the axial surface of the knob, and a first bevel gear is fixedly mounted on the bottom end of the axial surface of the first rotating rod.

[0008] Preferably, a second bevel gear is meshed on both sides of the outer surface of the first bevel gear, and a first threaded rod is fixedly installed on the side of the outer surface of the second bevel gear away from the first bevel gear. A moving block is threadedly installed on one end of the shaft surface of the first threaded rod, and the outer surface of the moving block is interactively installed on the mounting frame.

[0009] Preferably, a single-through hexagonal nylon stud is provided at the bottom of the outer surface of the housing, a HUB control board is installed at the top of the outer surface of the single-through hexagonal nylon stud, and a number of HUB connection ports are provided on the outer surface of the HUB control board.

[0010] Preferably, a connecting bracket is provided at the bottom of the outer surface of the housing, and several sets of single-pass hexagonal nylon studs are provided between the housing and the HUB control board. A positioning rod is inserted into the inside of the single-pass hexagonal nylon stud, and the connecting bracket, the housing and the HUB control board are installed through the shaft surface of the positioning rod. Cable outlet plugs are fixedly installed at the front and rear ends of the outer surface of the connecting bracket, and several sets of connecting holes are opened at the bottom of the outer surface of the connecting bracket.

[0011] Preferably, a slider is slidably mounted on the bottom of the outer surface of the connecting bracket, a sliding plate is mounted on the bottom of the outer surface of the slider, and a positioning hole is formed on the outer surface of the sliding plate.

[0012] Preferably, a positioning rod is inserted into the positioning hole of the moving plate, and a rotating handle is fixedly installed at the bottom end of the shaft surface of the positioning rod.

[0013] Preferably, a second limiting member is fixedly installed at the bottom of the outer surface of the moving plate, and a first limiting member is installed on the opposite side of the bottom of the outer surface of the moving plate to the second limiting member. A limiting groove is provided between the outer surfaces of the second limiting member and the first limiting member.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This solution proposes a foldable, splicable transparent display screen. Through the cooperation of connecting brackets and sliders, the movable plate is given flexible movement capability. Compared with traditional fixed structures, the position and angle of the display screen can be easily adjusted to meet diverse installation needs. The positioning holes of the movable plate, combined with positioning rods and rotating handles, make fine-tuning operations more precise and labor-saving. This fine adjustment is difficult to achieve in many existing products. The limiting protection mechanism composed of the first limiting component, the second limiting component, and the limiting groove ensures accurate alignment of each display screen during splicing, avoiding splicing failure or poor display effect due to positional deviation. At the same time, it effectively limits the movement range of the movable plate during folding, unfolding, and daily use, preventing collision damage and extending the service life of the equipment. These advantages greatly improve the practicality and stability of the product and represent a significant breakthrough in existing technologies. Attached Figure Description

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will be conceived by those skilled in the art.

[0026] Reference Figures 1-7As shown, a foldable and splicable transparent display screen includes: a mounting frame 1 and a substrate 2. The mounting frame 1 serves as the basic support structure of the entire display screen, possessing excellent mechanical strength and stability, effectively resisting various external impacts, and providing a solid guarantee for the reliable operation of the display screen in diverse usage environments. Two sets of mounting frames 1 are symmetrically distributed, and the substrate 2 is firmly fixed between them through a specific process. This ingenious design not only comprehensively protects the safety of the substrate 2, but also lays a solid foundation for the realization of a series of subsequent functions. As the core load-bearing component of the display screen, the quality of its design directly affects the performance of the display screen. On the middle of the outer surface of the substrate 2, several sets of mounting holes 3 are evenly distributed. These mounting holes 3 are standardized and mainly used to connect various functional components, such as to achieve the stable fixation of various electronic components, or to establish a connection channel with external devices, thereby greatly enhancing the scalability and versatility of the display screen. At the same time, several sets of holes 6 are carefully set on both sides of the outer surface of the substrate 2. These holes 6 have multiple practical functions. On the one hand, they can optimize the heat dissipation of the display screen. The thermal performance ensures that the heat generated by the internal electronic components during operation is dissipated quickly, maintaining the stable operation of the display screen. On the other hand, the aperture 6 greatly facilitates wiring, making the circuit layout more orderly and effectively avoiding signal interference caused by messy circuits. At the bottom of the outer surface of the substrate 2, there is a housing 16, whose main function is to provide comprehensive protection for the key components inside the display screen. It has functions such as dustproof, waterproof and impact-proof, which can significantly extend the overall service life of the display screen. At the end where the substrate 2 and the housing 16 are close to each other, several sets of nuts 18 are cleverly arranged. The outer surface of these nuts 18 is precisely located at the bottom of the mounting hole 3. This layout design creates favorable conditions for the installation of the positioning shaft 12. The positioning shaft 12 is installed through the outer surface of the housing 16 and the substrate 2, and the nuts 18 are tightly installed on the top of the shaft surface of the positioning shaft 12. Through the cooperation of the positioning shaft 12 and the nuts 18, a tight connection and stable installation between the substrate 2 and the housing 16 are successfully achieved, which also provides great convenience for subsequent disassembly and maintenance work.

[0027] Furthermore, a knob 4 is slidably mounted at the middle of the outer surface of the mounting frame 1. This design allows users to easily operate the knob 4. When the user rotates the knob 4, it slides smoothly along the surface of the mounting frame 1, providing initial power for the subsequent transmission process. The bottom end of the shaft surface of the knob 4 is firmly fixed to the first rotating rod 7, meaning that the rotation of the knob 4 can directly drive the first rotating rod 7 to rotate synchronously. The first rotating rod 7, as a key link in the transmission chain, transmits the power of the knob 4 to the next component. At the bottom end of the shaft surface of the first rotating rod 7, a first bevel gear 8 is fixedly mounted. The first bevel gear 8, the knob 4, and the first rotating rod 7 form a linked whole. As the first rotating rod 7 rotates, the first bevel gear 8 also begins to rotate. The two sides of the outer surface of the first bevel gear 8 mesh with the second bevel gear 9 respectively. This meshing method of bevel gears has unique advantages; it can change the direction of power transmission, converting the circular motion of the first bevel gear 8 into different directions of circular motion of the second bevel gear 9. When wheel 8 rotates, it drives the second bevel gear 9, which meshes with it, to rotate synchronously, thereby achieving efficient power transmission and direction conversion. On the side of the outer surface of the second bevel gear 9 away from the first bevel gear 8, a first threaded rod 10 is fixedly installed. This allows the rotation of the second bevel gear 9 to directly drive the rotation of the first threaded rod 10. One end of the shaft surface of the first threaded rod 10 is threadedly mounted with a moving block 11, and the outer surface of the moving block 11 is interactively mounted with the mounting frame 1. When the first threaded rod 10 rotates, due to the action of the thread, the moving block 11 will move linearly along the axial direction of the first threaded rod 10. At the same time, the interactive mounting of the moving block 11 with the mounting frame 1 ensures the stability and accuracy of the moving block 11 during the movement. Through such a transmission structure, the user can precisely control the position movement of the moving block 11 by rotating the knob 4, thereby realizing flexible adjustment of certain functions or structures of the display screen. For example, in the process of foldable splicing, it may be used to adjust the spacing or connection status between components, providing strong operational support for the foldable splicing function of the display screen.

[0028] Furthermore, the single-through hexagonal nylon stud 15 located at the bottom of the outer surface of the housing 16 has multiple functions. Firstly, from a mechanical perspective, it provides a stable support point for the installation of the HUB control board 14. This stud, made of nylon, has excellent insulation properties, effectively preventing short circuits caused by electrical connection problems and ensuring the electrical safety of the entire display screen. During installation, the HUB control board 14 is mounted through the top of the outer surface of the single-through hexagonal nylon stud 15. This installation method establishes a reliable connection between the HUB control board 14 and the housing 16, ensuring control... The stability of the board during equipment operation is ensured, preventing displacement or loosening due to vibration or external force. As one of the core components of the entire display screen control system, the HUB control board 14 has several sets of HUB connection ports 13 on its outer surface, which undertake extremely important data transmission and device connection tasks. These connection ports can be easily connected to external signal sources, control devices, etc., to achieve high-speed data transmission and interaction. For example, in commercial display scenarios, the display screen can be connected to computers, servers, and other devices through the HUB connection ports 13 to receive and display high-definition images, videos, and other content from these devices.In the intelligent control system, it can also communicate with other sensors, control modules, and other devices to achieve remote control and intelligent adjustment of parameters such as the display content, brightness, and color of the screen, greatly expanding the application range and functional diversity of the display screen. The connecting bracket 17 set at the bottom of the outer surface of the housing 16 provides an interface for the entire display screen to connect with external devices or mounting carriers, firmly installing the display screen in the required position. This design not only facilitates the installation and disassembly of the display screen, but also allows for flexible adjustment of the installation angle and position of the display screen according to different usage scenarios, meeting the diverse usage needs of users. It is particularly worth mentioning that several sets of... A single-pass hexagonal nylon stud 15 is used, and a positioning rod is inserted inside the stud 15. The connecting bracket 17, the housing 16, and the HUB control board 14 are mounted through the shaft surface of the positioning rod. This design greatly improves the stability and assembly accuracy of the entire structure. The positioning rod plays a precise positioning role during installation, ensuring that the relative positions of the connecting bracket 17, the housing 16, and the HUB control board 14 are accurate, avoiding component damage or malfunction due to installation deviations. At the same time, this structural design enhances the connection strength between various components, effectively dispersing stress when the equipment is subjected to external forces such as vibration and impact, ensuring the normal operation of the equipment, and providing a foldable assembly... The transparent display screen provides strong assurance for reliability in complex operating environments. The outer shell 16 and the connecting bracket 17 are tightly integrated to form the back profile, achieving a unified structure and creating a complete and continuous profile structure. This significantly reduces the installation process and required accessories, thereby lowering the overall installation cost. Furthermore, compared to spliced ​​structures, the integrated profile structure offers greater stability and reliability, effectively resisting deformation under various external forces. This provides a more robust and reliable support and protective foundation for the precision components inside the display screen. Cable exit plugs 5 are fixedly installed at both ends of the outer surface of the connecting bracket 17, effectively preventing cables from being exposed from the connecting bracket 17. To prevent damage to the wiring due to external friction or pulling, this design effectively protects the wiring and improves the overall neatness of the display screen. It also reduces the potential safety hazards caused by exposed wiring and eliminates the need for the original wiring concealment material. This adjustment not only simplifies the structure but also reduces production costs. The bottom of the outer surface of the connecting bracket 17 has several sets of connecting holes 26. These carefully designed holes allow for a direct and secure connection to the display screen bracket arm, providing a convenient way to install the display screen and ensuring stable connection to the bracket arm in various installation scenarios. This further enhances the installation flexibility and structural stability of the entire display screen system.

[0029] Furthermore, the connecting bracket 17, as the core hub connecting the display screen to the external mounting structure and other display screens, features a slidable slider 22 at its bottom. This allows the sliding plate 19 to move flexibly along a specific trajectory on the connecting bracket 17. The carefully designed sliding fit between the slider 22 and the connecting bracket 17 not only ensures smooth movement of the sliding plate 19 but also provides stable support during movement, effectively preventing the sliding plate 19 from shaking or shifting, thus ensuring the stability of the entire system. When the display screen is folded, the movement of the sliding plate 19 plays a crucial role. The positioning holes on the outer surface of the sliding plate 19 cooperate with the preset positioning points on the connecting bracket 17 during movement, ensuring that the sliding plate 19 can move accurately. Slide the plate to the predetermined position required for folding. Once the predetermined position is reached, rotate the ergonomically designed handle 21. The handle 21 drives the positioning rod 20, which is fixedly connected to it, to move. The positioning rod 20 inserts into the preset connection part of the connecting bracket 17, accurately fixing the position of the moving plate 19 and preparing it for the subsequent folding steps. At this time, the second limiting member 23 fixedly installed at the bottom of the outer surface of the moving plate 19, the first limiting member 24 located on its opposite side, and the limiting groove 25 set between them together constitute the key part of the foldable structure. During the folding process, when the moving plate 19 moves in a specific direction, the first limiting member 24 and the second limiting member 23 cooperate with each other to reduce the size of the equipment for easy storage and transportation, effectively reducing packaging size and transportation costs.

[0030] Working principle and implementation: During the installation phase, the connecting bracket 17 is first securely connected to the external mounting structure through the carefully designed connecting hole 26 at the bottom of its outer surface. If the position of the display screen needs to be adjusted later, the ergonomically designed handle 21 is rotated. The handle 21 drives the positioning rod 20, which is fixedly connected to it, to move. The positioning rod 20 moves in the positioning hole on the outer surface of the sliding plate 19, thereby precisely controlling the sliding plate 19 to slide along a specific trajectory on the connecting bracket 17. The sliding plate 19 relies on the slider 22, which is slidably installed on the bottom of the outer surface of the connecting bracket 17, to slide smoothly until it reaches the desired position, thus achieving fine-tuning of the display screen position. When splicing adjacent display screens, the spacing and relative position between them can be precisely controlled. When performing display screen splicing operations, the sliding plate 19 is first moved along the connecting bracket... The frame 17 slides to the predetermined splicing position. After reaching the predetermined position, the handle 21 is rotated. At this time, the positioning rod 20 is inserted into the preset connection part of the connecting bracket 17, thereby accurately fixing the position of the moving plate 19. During the folding process, the second limiting member 23 fixedly installed at the bottom of the outer surface of the moving plate 19, the first limiting member 24 located on its opposite side, and the limiting groove 25 set between them play a key role. When the folding operation is started, the moving plate 19 begins to slide. The first limiting member 24 and the second limiting member 23 cooperate with each other to guide the moving plate 19 to move in a specific direction along a predetermined trajectory. When the moving plate 19 moves to a specific position, the entire long device is folded into two sections with the position of the limiting groove 25 as the folding point, thereby effectively reducing the size, greatly facilitating storage and transportation, and significantly reducing packaging size and transportation costs. During the unfolding operation, under the coordinated action of the first limiting member 24, the second limiting member 23, and the limiting groove 25, the moving plate 19 moves in the opposite direction along the predetermined trajectory, so that the equipment returns to the initial unfolding state. The whole process ensures the safe and controllable operation of the equipment.
