Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to an escalator screen layout structure. Background Technology

[0002] Escalator screens are displays used on escalators. The screen is integrated with the escalator glass, and the control components are mounted above the step guide rail cover, achieving efficient space utilization and aesthetic integration. Their core advantage lies in their modular installation method, which does not affect the original escalator structure while providing multimedia information display functions. However, escalator screens generally suffer from numerous and messy internal cables. Power lines, signal lines, and other cables are tangled and intertwined, not only occupying installation space but also easily aging or causing poor contact due to bending and friction, increasing the risk of short circuits. The messy wiring also hinders heat dissipation, potentially causing localized overheating, and makes later maintenance difficult, requiring maintenance personnel to spend a significant amount of time tidying up and troubleshooting. Furthermore, the lack of effective cable fixing and protection makes the cables prone to loosening and falling off under the vibration of escalator operation, affecting equipment stability. Overall reliability and safety need to be improved. Utility Model Content

[0003] The main purpose of this utility model is to provide an escalator screen layout structure that optimizes the internal layout of the escalator screen, reduces connecting cables, and saves space.

[0004] To achieve the above objectives, this utility model proposes an escalator screen layout structure, comprising:

[0005] Display screen;

[0006] The base is connected to the bottom of the display screen. The base has an internal mounting cavity, in which a power supply component and a main control board are installed. A bridge board connects the power supply component and the main control board. The display screen is electrically connected to the main control board. The base has first wiring ports at both ends, and any two first wiring ports of the base can abut against each other to form a wiring channel.

[0007] In one possible implementation, the escalator screen layout structure further includes a plug, which can be connected to a first wiring port at any end of the base, and a second wiring port is provided at the bottom of the plug.

[0008] In one possible implementation, the plug has a ramp on the side away from the base.

[0009] In one possible implementation, the mounting cavity is provided with a protective cover above the bridging plate.

[0010] In one possible implementation, the mounting cavity is provided with waterproof guardrails at both ends near the first wiring port, and the power supply assembly and the main control board are disposed between the two waterproof guardrails.

[0011] In one possible implementation, the mounting cavity has a grounding copper post in the area between the waterproof guardrail and the first wiring port.

[0012] This utility model's technical solution reduces cable clutter and improves signal stability by connecting the power supply component and main control board via a bridge board. It also integrates a fuse function for enhanced safety. A waterproof panel isolates the cable routing ports from the core circuitry, and, together with the sloping end caps and grounding copper posts, achieves highly efficient waterproofing. The coordinated design of the first and second cable routing ports supports concealed wiring, adapting to multi-screen cascading or independent installations. The overall structure is compact, easy to maintain, and combines high reliability, safety, and aesthetics, making it perfectly suited for harsh environments such as shopping malls and subways, significantly reducing failure rates and maintenance costs.

[0021] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] Reference Figures 1 to 5 This utility model proposes an escalator screen layout structure, including a display screen 1 and a base 2. The base 2 is connected to the bottom of the display screen 1. An installation cavity 21 is formed inside the base 2. A power supply component 3 and a main control board 4 are arranged in the installation cavity 21. A bridge board 5 is connected between the power supply component 3 and the main control board 4. The display screen 1 is electrically connected to the main control board 4. First wiring ports 22 are opened at both ends of the base 2. Any two first wiring ports 22 of the base 2 can abut against each other to form a wiring channel.

[0024] Understandably, display screen 1 is a screen used to display information, attached to the glass on both sides of the escalator, and is the main part of the escalator screen. Base 2 is located at the bottom of display screen 1, installed on the foot plate of the escalator, and also contains functional components.

[0025] The base 2 has an internal cavity to house electronic components. The power supply module 3 supplies power to the display screen 1 and the main control board 4. The main control board 4 is the core circuit board controlling the operation of the display screen 1. The bridge board 5 is an intermediate circuit board connecting the power supply module 3 and the main control board 4, used for voltage conversion. The power supply module 3 supplies power to the main control board 4 through the bridge board 5, and the main control board 4 then directly controls the operation of the display screen 1. Using the bridge board 5 instead of traditional cables to connect the power supply module 3 and the main control board 4 has the following advantages: reduced cable count and simplified wiring. Traditional methods typically require multiple cables between the power supply module 3 and the main control board 4, resulting in complex wiring and space consumption. The bridge board 5 connects directly via the PCB, integrating multiple circuit paths, reducing the number of independent cables, making the internal layout simpler, reducing the risk of cable tangling and loosening, improving reliability, and saving space in the mounting cavity 21, facilitating the layout of other components. In addition, in this example, the bridge board 5 integrates a protection unit, such as a fuse, a resettable fuse (PTC), and an overvoltage / overcurrent protection circuit, which automatically cuts off or limits the current when the power supply is abnormal, protecting the main control board 4 and the display screen 1 and enhancing electrical safety.

[0026] The first cable routing port 22 is an opening at both ends of the base 2, used for the passage of cables such as power cables and signal cables. When the cable routing ports of two bases 2 are connected, a continuous channel is formed, facilitating the concealed and neat routing of cables among multiple display screen units 1. This is suitable for scenarios where multiple screens are installed consecutively next to escalators. Through this design, the docking of the bases 2 enables the combined installation of multiple screens, simplifies wiring, hides cables, avoids exposed clutter, and reduces the risk of external damage. When multiple such display screens 1 are installed on both sides of a shopping mall escalator, the bases 2 are connected end to end, and the cable routing ports are aligned to form a channel. Cables can be connected to each screen through the channel without being exposed, maintaining an overall neat appearance.

[0027] Reference Figures 1 to 2 In one embodiment of this utility model, the escalator screen layout structure also includes a plug 6, which can be connected to the first wiring port 22 at any end of the base 2, and the bottom of the plug 6 is provided with a second wiring port 61.

[0028] Understandably, the plug 6 is a closed component used to cover the first cable routing port 22 at the end of the base 2. When the base 2 of the escalator screen does not need to be connected to other bases 2, such as when it is at the end of a row of display screens 1, the plug 6 can be used to close the unused cable routing port, serving the functions of dust prevention, waterproofing, and aesthetics. The plug 6 can be fixed to one end of the base 2 by physical clips, screws, or plug-ins, etc., which is not limited here.

[0029] The second cable routing port 61 is located at the bottom of the plug 6, and its direction is different from that of the first cable routing port 22 of the base 2, which can change the direction of the cable. After the plug 6 is installed, the cable can be led out through the second cable routing port 61 at the bottom of the plug 6, for example, by running the cable downwards to the ground or by hiding the cable to the side, avoiding exposure at the end and flexibly adapting to different installation scenarios.

[0030] Reference Figures 1 to 2 In one embodiment of this utility model, the plug 6 is provided with a ramp 62 on the side away from the base 2.

[0031] Understandably, the core function of the ramp 62 is waterproofing and dustproofing, specifically in the following aspects: guiding water flow, the ramp design prevents water droplets and dust from accumulating on the surface of the plug 6, allowing them to slide off naturally and preventing seepage into the base 2; reducing water accumulation at joints, as traditional flat plugs 6 are prone to water accumulation at joints, which may lead to corrosion or short circuits over time, while the ramp structure effectively avoids this problem; adapting to outdoor / humid environments, suitable for places such as subways and shopping malls, preventing water stains from entering during escalator cleaning. In addition, it enhances aesthetics and safety, the ramp design makes the plug 6 more harmonious with the overall style of the display screen 1, avoiding abrupt right-angle edges and improving the industrial design quality; the ramp replaces right-angle edges, reducing the risk of injury to pedestrians or maintenance personnel from accidental collisions.

[0032] Reference Figures 3 to 5 In one embodiment of this utility model, a protective cover plate 41 is provided on the mounting cavity 21 above the bridging plate 5.

[0033] Understandably, the core functions of the protective cover 41 are: to block dust / debris. Escalator environments such as shopping malls and subways easily accumulate dust; the cover prevents contaminants from falling into the bridge board 5 or main control board 4, avoiding short circuits or poor contact; to prevent accidental contact or tool drops. If tools accidentally slip during maintenance, the cover protects precision electronic components from impact damage; in addition, the metal cover can also serve as a shielding layer. If made of metal, it can reduce the impact of external electromagnetic interference on the signal transmission of the bridge board 5. The cover can be fixed with screws or clips, making disassembly convenient and facilitating technicians to inspect or replace the bridge board 5 and fuse components.

[0034] Reference Figures 3 to 5 In one embodiment of the present invention, the mounting cavity 21 is provided with waterproof guardrails 211 at both ends near the first wiring port 22, and the power supply assembly 3 and the main control board 4 are disposed between the two waterproof guardrails 211.

[0035] Understandably, the core function of the waterproof barrier 211 is to prevent external water stains from intruding. The first cable routing opening 22 is the channel for cables to enter and exit the installation cavity 21, and it is also a high-risk area where water vapor / liquid may seep in. The waterproof barrier 211 forms a physical barrier on the inside of the cable routing opening to prevent water from flowing into the power supply and main control board 4 area along the cables or gaps. The slope on the outside of the plug 6 diverts water, and the inner waterproof barrier 211 further intercepts residual water stains, forming double protection.

[0036] Reference Figures 3 to 5 In one embodiment of this utility model, a grounding copper post 212 is provided in the area between the waterproof guardrail 211 and the first wiring port 22 in the mounting cavity 21.

[0037] Understandably, the grounding copper post 212 is used for safety grounding protection, providing a low-impedance grounding path for the power supply component 3 and the main control board 4, ensuring that leakage current is promptly conducted to the ground, and also eliminating common-mode interference introduced by cables. It is particularly suitable for escalator scenarios with long-distance wiring, reducing grounding loop interference in the signal transmission of the display screen 1.

[0038] This utility model's technical solution connects the power supply component 3 and the main control board 4 via a bridge board 5, reducing cable clutter, improving signal stability, and integrating a fuse function to enhance safety. A waterproof barrier 211 isolates the wiring ports from the core circuitry, and together with the sloping end cap 62 and grounding copper post 212, achieves efficient waterproofing. The coordinated design of the first wiring port 22 and the second wiring port 61 supports concealed wiring, adapting to multi-screen cascading or independent installation. The overall structure is compact, easy to maintain, and combines high reliability, safety, and aesthetics, perfectly suited for harsh environments such as shopping malls and subways, significantly reducing failure rates and maintenance costs.
