Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and in particular to an escalator screen. Background Art

[0002] Since their invention in the late 19th century, escalators, as an efficient and convenient means of continuous transportation, have been widely used in public places such as shopping malls, subways, and airports, significantly improving pedestrian mobility and optimizing space planning. However, traditional escalator designs suffer from significant resource waste—the glass or metal panels on either side typically serve only as safety barriers and are not effectively utilized. This current design flaw results in low space utilization and missed opportunities for revenue growth and service optimization through digital upgrades. Summary of the Invention

[0003] The main purpose of the present invention is to provide an escalator screen, which is designed to be installed on the baffles on both sides of the escalator. It can not only play advertisements, public notices or artistic content to create commercial value, but also enhance the user experience through intelligent interactive functions (such as navigation guidance and emergency alarms), while meeting the requirements of modern smart cities for the multifunctionalization of infrastructure.

[0004] To achieve the above-mentioned purpose, the present invention proposes an escalator screen, comprising:

[0005] Display screen;

[0006] The base is connected to the bottom of the display screen, an installation cavity is formed inside the base, a control component is arranged in the installation cavity, the display screen is electrically connected to the control component, and connection ports are opened at both ends of the base. The connection ports of any two bases can abut against each other to form a wiring channel.

[0007] In a possible embodiment, the control component includes at least a power supply and a main control board, and a bridge board is connected between the power supply and the main control board. A first wiring portion is provided on the main control board, and the display screen is electrically connected to the first wiring portion.

[0008] In a possible implementation, an adapter plate is connected to the bottom of the display screen, a second wiring portion is provided on a surface of the adapter plate, and a flat cable is detachably connected between the second wiring portion and the first wiring portion.

[0009] In a possible implementation, the base includes an upper shell and a lower shell, and a portion of the edge of the upper shell at least covers the area between the base and the adapter plate.

[0010] In a possible implementation, the adapter plate is provided with a first waterproof housing in an area corresponding to the second wiring portion, and a wiring opening is provided on a lower side of the first waterproof housing for the wiring to pass through.

[0011] In a possible embodiment, a protective plate is further provided above the control assembly in the installation cavity, and the protective plate is bent on one side close to the adapter plate to form a bent portion, the bent portion is located on the outside of the lower shell and a gap is left between the two to allow the cable to pass through.

[0012] In a possible embodiment, both ends of the protective plate are bent multiple times near the connection port to form a stepped water diversion structure, and drainage ports are provided at both ends of the bottom of the installation cavity corresponding to the water diversion structure.

[0013] In a possible implementation, waterproof baffles are provided at both ends of the bottom of the installation cavity below the water diversion structure, and the control assembly is provided between the two waterproof baffles.

[0014] In a possible implementation manner, the adapter plate is covered with a second waterproof shell in an area outside the second wiring portion.

[0015] In a possible embodiment, the escalator screen further includes a plug, which can be connected to a connection port at any end of the base, and a wiring port is provided at the bottom of the plug.

[0016] The technical solution of the present invention has excellent waterproof performance and reliability by adopting a multi-layer protection design.

[0027] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0028] Reference Figures 1 to 6 The present invention proposes an escalator screen, including a display screen 1 and a base 2, the base 2 is connected to the bottom end of the display screen 1, an installation cavity 3 is formed inside the base 2, a control component is arranged in the installation cavity 3, the display screen 1 is electrically connected to the control component, and connection ports 4 are opened at both ends of the base 2, and the connection ports 4 of any two bases 2 can abut against each other to form a wiring channel.

[0029] As you can understand, display screen 1 is a screen used to display information. It is attached to the glass on both sides of the escalator and is the main component of the escalator screen. Base 2 is located at the bottom of display screen 1 and is mounted on the escalator's footboard. It also houses functional components. Base 2 has a cavity inside for accommodating electronic components. The control assembly is the core structure that controls the operation of display screen 1. It includes a power supply 5, a PCB board, and other components, directly controlling the operation of display screen 1.

[0030] The connection port 4 is a through-hole opened at both ends of the base 2 for the passage of cables such as power lines 5 and signal lines. When the connection ports 4 of two bases 2 are docked, a continuous channel is formed, which facilitates the concealed and neat laying of cables between multiple display screens 1 units. It is suitable for the scenario of installing multiple screens in succession next to escalators. Through this design, the docking of the bases 2 realizes the installation of multiple screens, simplifies wiring, hides the cables, avoids exposure and clutter, and reduces the risk of damage from external forces. When multiple such display screens 1 are installed on both sides of the escalator in a shopping mall, the bases 2 are connected end to end, and the connection ports 4 are aligned to form a channel. The cables can be connected in series through the channel to connect the screens without being exposed, keeping the overall cleanliness.

[0031] Reference Figures 3 to 6 In one embodiment of the present invention, the control component includes at least a power supply 5 and a main control board 6, and a bridge board 51 is connected between the power supply 5 and the main control board 6. A first wiring portion 61 is provided on the main control board 6, and the display screen 1 is electrically connected to the first wiring portion 61.

[0032] It can be understood that the power supply 5 is a module that supplies power to the display screen 1 and the main control board 6. The main control board 6 is the core circuit board that controls the operation of the display screen 1 and is connected to the display screen 1 via the first connection portion 61. The bridge board 51 is an intermediate circuit board that connects the power supply 5 and the main control board 6 and is used for voltage conversion. The power supply 5 supplies power to the main control board 6 via the bridge board 51, and the main control board 6 directly controls the operation of the display screen 1. Using the bridge board 51 instead of traditional cables to connect the power supply 5 and the main control board 6 has the following advantages: reducing the number of cables and simplifying wiring. The traditional method usually requires multiple cables between the power supply 5 and the main control board 6, which is complex and takes up space. The bridge board 51 is directly connected through the PCB, integrating multiple circuit paths, reducing the number of independent cables, making the internal layout simpler, reducing the risk of cable entanglement and loosening, and improving reliability. At the same time, it saves space in the installation cavity 3 and facilitates the layout of other components. In addition, in this example, the bridge board 51 is integrated with insurance units, such as fuses, resettable fuses (PTCs), overvoltage / overcurrent protection circuits, etc., which automatically cut off or limit the current when the power supply 5 is abnormal, thereby protecting the main control board 6 and the display screen 1 and enhancing electrical safety.

[0033] Reference Figures 3 to 6 In one embodiment of the present invention, a transfer board 11 is connected to the bottom of the display screen 1, a second wiring portion 12 is provided on the surface of the transfer board 11, and a flat cable 7 is detachably connected between the second wiring portion 12 and the first wiring portion 61.

[0034] As can be understood, the adapter board 11 is fixed to the bottom of the display screen 1 and serves as the circuit board for connecting the display screen 1 to the main control base 2. The second connection portion 12, located on the surface of the adapter board 11, serves as the interface for the flat cable 7. The flat cable 7 extends from the first connection portion 61 of the main control board 6 and then connects to the second connection portion 12 on the adapter board 11. The flat cable 7 is detachable. This arrangement creates a modular structure for the escalator screen, allowing the display screen 1, base 2, and the control components within the base 2 to be detached and separated, simplifying installation and maintenance.

[0035] Reference Figures 4 to 6 In one embodiment of the present invention, the base 2 includes an upper shell 21 and a lower shell 22 , and a portion of the edge of the upper shell 21 at least covers the area between the base 2 and the adapter plate 11 .

[0036] As can be understood, the base 2 is assembled from two upper and lower shells, forming a mounting cavity 3 for accommodating the control components. The upper shell 21 is an L-shaped structure, providing comprehensive protection for the connection area between the base 2 and the adapter plate 11. The upper shell 21 at least covers the entire exposed area between the base 2 and the adapter plate 11, including the second terminal block 12 and the exposed portion of the flat cable 7, extending from the top surface of the base 2 to the upper edge of the adapter plate 11. Its core functions are top splash protection, preventing rainwater and cleaning liquids from directly wetting the connecting components from above, and physical isolation, preventing foreign matter such as dust and metal debris from falling into the terminal block or the flat cable 7.

[0037] Reference Figures 5 to 6 In one embodiment of the present invention, the adapter plate 11 is provided with a first waterproof housing 13 in an area corresponding to the second wiring portion 12 , and a wiring opening 14 is provided on the lower side of the first waterproof housing 13 to allow the cable 7 to pass through.

[0038] It can be understood that the first waterproof shell 13 covers the second wiring part 12 area of the adapter plate 11 to play a waterproof role. The wiring opening 14 is a hole opened on the waterproof shell for the cable 7 to enter the shell and connect with the second wiring part 12.

[0039] The cable opening 14 is located on the underside of the first waterproof housing 13, near the bottom. It faces vertically or diagonally downward. After exiting the base 2, the cable 7 is inserted upward through the lower cable opening 14 of the first waterproof housing 13, forming a U-shaped path. If water droplets adhere to the cable 7, they will naturally drip downward due to gravity and will not be able to flow upward into the cable opening 14. Furthermore, the inside of the cable opening 14 can be filled with a waterproof rubber ring or sealant to further prevent water from entering through the gap.

[0040] Reference Figures 3 to 6In one embodiment of the present invention, a protective plate 8 is further provided above the control assembly in the installation cavity 3, and the protective plate 8 is bent on one side close to the adapter plate 11 to form a bent portion 81. The bent portion 81 is located on the outer side of the lower shell 22 and a gap is left between the two to allow the cable 7 to pass through.

[0041] As you can understand, the protective plate 8 is installed above the control assembly to prevent liquid from dripping directly onto the control assembly. The bent portion 81 is where the protective plate 8 bends inward on the side closest to the adapter plate 11, where the wiring is required, forming an extended structure. The bent portion 81 is located on the outside of the lower shell 22, leaving a gap between it and the lower shell 22. This gap serves as the wiring channel through which the cable 7 passes and exits the base 2.

[0042] It should be noted that the above setting will make the outlet direction of the wiring channel vertically downward, which is the core of the waterproof design. Even if water flows along the surface of the cable 7, it will naturally drip due to gravity and will not flow back into the base 2; the bent portion 81 covers the outside of the lower shell 22 like an eaves, forming a physical barrier to reduce the possibility of rainwater directly splashing into the wiring channel; after the cable 7 passes through the downward wiring channel, it goes upward into the waterproof shell of the adapter plate 11, forming a path that goes first down and then up, further blocking the water infiltration path.

[0043] Reference Figures 3 to 6 In one embodiment of the present invention, both ends of the protective plate 8 are bent multiple times near the connection port 4 to form a stepped water diversion structure 82, and drainage ports 31 are provided at both ends of the bottom of the installation cavity 3 corresponding to the water diversion structure 82.

[0044] Understandably, the protective plate 8 has a stepped structure with multiple bends at both ends, forming a water diversion structure 82. The function of the stepped structure is to divert water in layers. The multiple bends form a stepped structure that guides the water flow step by step, preventing the liquid from dripping directly from a high altitude to the bottom of the installation cavity 3 due to gravity, forming a large splash and splashing onto the control component; it also slows down the water flow. The stepped bends can reduce the impact force of the liquid flow and prevent the liquid from splashing or backflowing; and it expands the drainage path. Compared with a straight baffle, the stepped structure increases the liquid flow path, ensuring that water is effectively directed to the drain outlet 31.

[0045] The two ends of the protective plate 8 are bent downward like "steps" to form a height difference. After the liquid enters the installation cavity 3, it is first blocked by the protective plate 8. Due to the existence of the stepped structure, the water will flow downward along the steps step by step and finally converge to the low points at both ends of the protective plate 8. The water flow is guided to the drain port 31 and discharged to the outside of the base 2 to avoid water accumulation.

[0046] This design optimizes the liquid diversion path through the stepped curved protective plate 8, ensuring that water is discharged quickly and stably, thereby enhancing the waterproof ability of the control component and is suitable for application scenarios susceptible to humid environments such as escalators.

[0047] Reference Figures 3 to 6 In one embodiment of the present invention, waterproof baffles 32 are provided at both ends of the bottom of the installation cavity 3 below the water diversion structure 82 , and the control component is provided between the two waterproof baffles 32 .

[0048] As will be appreciated, waterproof baffles 32 are added at both ends of the bottom of the installation cavity 3 to isolate the control unit from the drainage area and prevent liquid backflow or splashing. These baffles 32 are located at both ends of the bottom of the installation cavity 3, corresponding to below the water diversion structure 82. They can be vertical or inclined baffles, low in height, to block water flow. The baffles 32 at both ends form a fence structure, and the control unit is installed between the two baffles 32, creating a relatively closed and protected area.

[0049] The function of the waterproof guardrail 32 is to isolate the drainage area from the control component. The liquid (such as rainwater, condensation water) flowing down from the water diversion structure 82 will enter the drain outlet 31 at both ends of the base 2; the waterproof guardrail 32 acts as a physical barrier to prevent water from seeping back or splashing onto the control component; it guides the liquid to be discharged in a directional manner. After the liquid flows down the stepped structure of the protective plate 8, it is restricted by the waterproof guardrail 32 to the edge drainage channel and finally discharged from the drain outlet 31.

[0050] Reference Figures 4 to 6 In one embodiment of the present invention, the adapter plate 11 is covered with a second waterproof housing 15 in an area outside the second wiring portion 12 .

[0051] Understandably, the first waterproof housing 13 specifically protects the second wiring section 12, the core interface for connecting to the flat cable 7. It is higher than the second waterproof housing 15, forming a "raised" structure. This facilitates wiring insertion, as the higher space makes it easier for operators to plug and unplug the flat cable 7 or adjust the interface; it also provides centralized protection, specifically strengthening the waterproofness of the wiring area. The second waterproof housing 15 covers the entire area of the adapter plate 11 except for the second wiring section 12. It is lower than the first waterproof housing 13, preventing moisture or liquid from invading other areas of the adapter plate 11. It forms a stepped structure with the first housing to prevent the entire structure from being too high, which could affect installation.

[0052] Reference Figures 1 to 4 In one embodiment of the present invention, the escalator screen further includes a plug 9, which can be connected to the connection port 4 at any end of the base 2, and a wiring port 91 is provided at the bottom of the plug 9.

[0053] As can be understood, plug 9 is a sealing component used to cover the connection port 4 at the end of the base 2. When the base 2 of the escalator screen does not need to be docked with other bases 2, such as at the end of a row of display screens 1, plug 9 can be used to seal the unused connection port 4, providing dustproof, waterproof, and aesthetically pleasing effects. Plug 9 can be secured to one end of the base 2 by physical clips, screws, or plug-in connections, without limitation.

[0054] A wiring port 91 is located at the bottom of the plug 9, facing in a different direction from the connection port 4 of the base 2, allowing for flexible cable routing. Once the plug 9 is installed, cables can be routed through the wiring port 91, for example, down to the floor or hidden laterally, avoiding exposed ends and flexibly adapting to different installation scenarios.

[0055] The technical solution of the present invention has excellent waterproof performance and reliability by adopting a multi-layer protection design. The protective plate 8 forms a water diversion structure 82 through stepped bending, and cooperates with the waterproof guardrail 32 at the bottom to effectively guide the liquid to the drain outlets 31 at both ends to prevent the control components from getting wet; the adapter plate 11 is installed with high and low double waterproof shells, the high shell protects the wiring part and has a lower wiring port 14, and the low shell covers the rest of the area to achieve all-round sealing; the wiring path 7 strictly follows the "low in and high out" principle, using gravity to block the backflow of liquid; the power supply 5 and the main control board 6 are connected through the bridge board 51, which reduces cable clutter and improves signal stability. At the same time, it integrates a safety function to enhance safety; the coordinated design of the wiring port 91 and the connection port 4 supports concealed wiring and is suitable for multi-screen series or independent installation. The overall structure is compact and easy to maintain, with high reliability, safety and aesthetics. It is perfectly adapted to harsh environments such as shopping malls and subways, and significantly reduces failure rate and maintenance costs.
