Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a waterproof structure for the connection point of an escalator screen. 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 covers, achieving efficient space utilization and aesthetic integration. Its core advantage lies in its modular installation method, which does not affect the original escalator structure while still enabling multimedia information display. However, this design faces significant challenges when used outdoors: although the control components are housed in a protective casing, the connection structure between them and the display screen remains exposed, requiring protection against risks such as rainwater infiltration and condensation buildup. Existing ordinary protective structures cannot completely prevent damage from harsh environmental factors such as water gun cleaning and rain erosion during the rainy season, potentially leading to short circuits in electronic components or corrosion of metal parts. Utility Model Content

[0003] The main purpose of this utility model is to provide a waterproof structure for the connection point of an escalator screen, which aims to provide reliable waterproof protection for the connection point between the display screen and the control components.

[0004] To achieve the above objectives, this utility model proposes a waterproof structure for escalator screen connection points, comprising:

[0005] The display screen has an adapter plate connected to its bottom. The adapter plate has a first wiring portion on its surface and a first waterproof housing in the area corresponding to the first wiring portion. The first waterproof housing has a cable routing port.

[0006] The main control base is located adjacent to the adapter plate. The main control base contains a main control board, which has a second wiring section connected to a ribbon cable. The main control base has a wiring channel on the side facing the adapter plate. The ribbon cable passes through the wiring channel to the outside of the main control base, then enters the first waterproof housing from the wiring port and connects to the first wiring section.

[0007] In one possible implementation, the main control base includes an upper shell and a lower shell, wherein the upper shell is bent on the side near 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 form the wiring channel.

[0008] In one possible implementation, the wiring port is located on the lower side of the first waterproof housing.

[0009] In one possible implementation, the adapter plate is covered with a second waterproof housing in the area outside the first wiring section.

[0010] In one possible implementation, the adapter plate has a waterproof strip on its periphery, and the waterproof strip is located at the connection between the adapter plate and the second waterproof housing.

[0011] In one possible implementation, a waterproof cover is provided above the main control base, and the waterproof cover covers at least the area between the main control base and the adapter plate.

[0012] This utility model's technical solution employs an adapter plate to install a dual-layer waterproof housing with varying heights. The higher housing protects the wiring section and features a lower cable routing port, while the lower housing covers the remaining area. Combined with peripheral waterproof strips, this achieves a comprehensive seal. The main control base features a split upper and lower housing design, with the upper housing bent to form a downward-facing cable routing channel. This, along with the top waterproof cover, creates a "roof-like" splash-proof barrier. The cable routing strictly adheres to the "low in, high out" principle, utilizing gravity to prevent liquid backflow. The components are bonded together using waterproof strips, sealing rings, and structural compression to form a three-dimensional protective structure. This design combines dust and water resistance with convenient maintenance, effectively addressing rainwater erosion, high-pressure cleaning, and condensation corrosion in escalator environments. This significantly improves the reliability and lifespan of the display screen under humid and harsh conditions. Attached Figure Description

[0020] 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.

[0021] Reference Figures 1 to 3 This utility model proposes a waterproof structure for the connection point of an escalator screen, including a display screen 1 and a main control base 3. The bottom of the display screen 1 is connected to an adapter plate 2. The surface of the adapter plate 2 is provided with a first wiring part 21, and the adapter plate 2 is provided with a first waterproof shell 22 in the area corresponding to the first wiring part 21. The first waterproof shell 22 is provided with a cable routing port 23. The main control base 3 is located adjacent to the adapter plate 2. The main control base 3 is provided with a main control board 4 inside. The main control board 4 is provided with a second wiring part 41. The second wiring part 41 is connected to a ribbon cable 42. The main control base 3 is provided with a cable routing channel 5 on the side facing the adapter plate 2. The ribbon cable 42 passes through the cable routing channel 5 to the outside of the main control base 3, and then enters the interior of the first waterproof shell 22 from the cable routing port 23 and connects with the first wiring part 21.

[0022] Understandably, the display screen 1 is a display device that is attached to the glass of the escalator. The main control base 3 is installed on the foot plate of the escalator and contains a main control board 4 that controls the display screen 1. The adapter board 2 is fixed to the bottom of the display screen 1 and is a circuit board used to connect the display screen 1 and the main control base 3.

[0023] The first connector 21 is located on the surface of the adapter plate 2 and serves as the interface for connecting the ribbon cable 42. The first waterproof housing 22 covers the area of ​​the first connector 21 on the adapter plate 2, providing waterproofing. The cable routing port 23 is a hole opened on the waterproof housing, allowing the ribbon cable 42 to enter the housing and connect to the first connector 21.

[0024] The main control base 3 has an internal cavity for housing the main control board 4. The main control board 4 is the core circuit board for controlling the display screen 1 and has a second wiring section 41. The ribbon cable 42 is led out from the second wiring section 41 of the main control board 4 and is used to connect to the first wiring section 21 of the adapter board 2. The wiring channel 5 is an opening on the side of the main control base 3 through which the ribbon cable 42 extends to the outside of the main control base 3. The ribbon cable 42 first leads out from the second wiring section 41 of the main control base 3, passes through the wiring channel 5 to exit the main control base 3, reaches the outside, and then enters the interior of the first waterproof housing 22 through the wiring port 23 of the waterproof housing of the adapter board 2. Inside the waterproof housing, the ribbon cable 42 connects to the first wiring section 21 of the adapter board 2.

[0025] The first waterproof housing 22 protects the wiring portion of the adapter plate 2, preventing moisture or liquid intrusion. The cooperation between the wiring port 23 and the wiring channel 5 restricts the path of the wiring 42 to the outside of the waterproof housing and the main control base 3, while the connection points are protected inside, reducing external exposure and lowering the risk of water ingress. The above structure is suitable for outdoor escalators, such as the display screen 1 of escalators in squares and subways, ensuring that the connection between the display screen 1 and the control base remains waterproof and moisture-proof in humid or dusty environments, improving equipment reliability.

[0026] Reference Figures 2 to 3 In one embodiment of this utility model, the main control base 3 includes an upper shell 6 and a lower shell 7. The upper shell 6 is bent on the side near the adapter plate 2 to form a bent portion 61. The bent portion 61 is located on the outside of the lower shell 7 and there is a gap between the two to form a wiring channel 5.

[0027] Understandably, the main control base 3 is assembled from two shell parts, forming a mounting cavity for placing the main control board 4. The bending part 61 is formed by bending the upper shell 6 inward on the side near the adapter plate 2, i.e., the side where the cable needs to be routed, forming an extension structure. The bending part 61 is located on the outside of the lower shell 7, leaving a gap between it and the lower shell 7. This gap is the cable routing channel 5, through which the ribbon cable 42 passes out of the main control base 3.

[0028] It should be noted that the above-mentioned arrangement will make the outlet direction of the wiring channel 5 vertically downward. This is the core of the waterproof design. Even if water flows along the surface of the ribbon cable 42, it will drip off naturally due to gravity and will not flow back into the main control base 3. The bend 61 covers the outside of the lower shell 7 like an eave, forming a physical shield and reducing the possibility of rainwater splashing directly into the wiring channel 5. After the ribbon cable 42 exits from the downward wiring channel 5, it enters the waterproof shell of the adapter plate 2 upward, forming a bottom-up path, which further blocks the water penetration path.

[0029] Reference Figures 2 to 3 In one embodiment of this utility model, the wiring port 23 is located on the lower side of the first waterproof housing 22.

[0030] Understandably, the wiring opening 23 is located on the lower side of the first waterproof housing 22, that is, near the bottom of the housing, with the opening direction being vertical or diagonally downward. After the ribbon cable 42 exits from the wiring channel 5 of the main control base 3, it is inserted into the lower wiring opening 23 of the first waterproof housing 22 from bottom to top, forming a "U-shaped" path. If external water droplets adhere to the ribbon cable 42, they will naturally drip downward due to gravity and will not be able to flow upward into the wiring opening 23. Furthermore, the inside of the wiring opening 23 can be filled with a waterproof rubber ring or sealant to further prevent water from entering through gaps.

[0031] Reference Figures 2 to 3In one embodiment of the present invention, the adapter plate 2 is covered with a second waterproof housing 24 in the area other than the first wiring portion 21.

[0032] Understandably, the first waterproof housing 22 specifically protects the first wiring section 21, which is the core interface connecting to the main control base 3 ribbon cable 42. It is higher than the second waterproof housing 24, forming a "protruding" structure. This design facilitates cable insertion, as the higher space allows operators to easily plug and unplug the ribbon cable 42 or adjust the interface; it also provides centralized protection, focusing on enhancing the waterproofness of the wiring section. The second waterproof housing 24 covers all areas of the adapter plate 2 except for the first wiring section 21. It is lower than the first waterproof housing 22, preventing moisture or liquid from entering other areas of the adapter plate 2. It forms a stepped structure with the first housing, avoiding an overall height that would affect installation.

[0033] Reference Figures 2 to 3 In one embodiment of the present invention, the adapter plate 2 is provided with a waterproof adhesive strip 25 on its periphery, and the waterproof adhesive strip 25 is located at the connection between the adapter plate 2 and the second waterproof shell 24.

[0034] Understandably, the waterproof strip 25 is located around the periphery of the adapter plate 2, that is, the contact surface around the edge of the adapter plate 2. Specifically, it is clamped at the connection between the adapter plate 2 and the second waterproof housing 24, and the strip is pressed tightly when the housing covers the adapter plate 2. The core function of the strip is to seal the gaps and prevent external moisture and dust from seeping in from the joint between the second waterproof housing 24 and the adapter plate 2; it also provides shock absorption and cushioning, as the material of the strip can mitigate the impact of vibration on the housing connection.

[0035] The second waterproof housing 24 can be fixed to the adapter plate 2 by screws or clips, and the waterproof strip 25 is pressed together to form a sealed space. The thickness of the strip needs to be slightly greater than the theoretical gap between the adapter plate 2 and the housing to ensure that there are no gaps after pressing.

[0036] Reference Figures 2 to 3 In one embodiment of this utility model, a waterproof cover plate 8 is provided above the main control base 3, and the waterproof cover plate 8 covers at least the area between the main control base 3 and the adapter plate 2.

[0037] Understandably, by adding a waterproof cover plate 8 above the main control base 3, overall protection of the connection area between the main control base 3 and the adapter plate 2 is achieved. The waterproof cover plate 8 at least covers all exposed areas between the main control base 3 and the adapter plate 2, including the wiring channel 5 and the exposed portion of the ribbon cable 42, extending from the upper surface of the main control base 3 to the upper edge of the second waterproof housing 24 of the adapter plate 2. Its core functions are top splash protection, preventing rainwater and cleaning liquids from directly wetting the connecting components; and physical isolation, preventing foreign objects such as dust and metal shavings from falling into the wiring channel 5 or the wiring section.

[0038] This utility model's technical solution employs an adapter plate 2 to install a high and low dual waterproof housing. The high housing protects the wiring section and has a lower cable routing port 23, while the low housing covers the remaining area. Combined with the peripheral waterproof strip 25, it achieves all-round sealing. The main control base 3 has a split design with upper and lower housings 7. The upper housing 6 is bent to form a downward-facing cable routing channel 5, which, together with the top waterproof cover plate 8, forms a "roof-like" splash-proof barrier. The cable routing path 42 strictly follows the "low in, high out" principle, using gravity to block liquid backflow. The components are connected by waterproof strips 25, sealing rings, and structural pressing to form a three-dimensional protective structure, which combines dustproof and waterproof capabilities with convenient maintenance. It effectively copes with rainwater erosion, high-pressure cleaning, and condensation corrosion in the escalator environment, significantly improving the reliability and lifespan of the display screen 1 under humid and harsh working conditions.
