[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0029] See Figures 1 to 5As shown, the platform safety door audible and visual warning device provided in this application includes a fixed base, an umbrella-shaped protrusion 10 is provided at the center of the fixed base, an installation ring seat 4 is provided above the fixed base through the umbrella-shaped protrusion 10, a warning component is provided at the top of the installation ring seat 4, and a snap-fit ​​compartment 11 is opened at the bottom. The snap-fit ​​compartment 11 is connected to the fixed base through a locking mechanism 8 on both sides by engaging with the umbrella-shaped protrusion 10. The locking mechanism 8 is provided inside the side wall of the snap-fit ​​compartment 11.

[0030] The fixed base is fixed to the platform safety door with bolts. After the fixed base is fixed, the installer needs to align the snap-fit ​​compartment 11 of the installation ring seat 4 with the umbrella-shaped protrusion 10 and move the installation ring seat 4 in the direction close to the fixed base until the locking mechanism 8 in the snap-fit ​​compartment 11 and the umbrella-shaped protrusion 10 are engaged, so as to quickly complete the installation of the warning device.

[0031] When maintenance or adjustment of the early warning device is required, the locking mechanism 8 can be used to quickly release the locking state of the umbrella-shaped boss 10, so that the mounting ring seat 4 can be separated from the fixed base, making it convenient for maintenance personnel to inspect and adjust the inside of the device.

[0032] The locking mechanism 8 includes a limiting slide 81, an adjusting slide 82, and a locking slide 83, all located within the side wall of the latching compartment 11. A locking slide 84 is slidably disposed within the limiting slide 81. A connecting shaft 89 is provided at one end of the locking slide 84 away from the umbrella-shaped protrusion 10. A connecting rod 85 is rotatably disposed on the connecting shaft 89. An adjusting slide plate 86 is rotatably disposed at one end of the connecting rod 85 away from the locking slide 84. The adjusting slide plate 86 is slidably disposed within the adjusting slide 82. An adjusting spring 810 is provided between the adjusting slide plate 86 and the top of the adjusting slide 82. The adjusting slide plate 86 is slidably disposed within the locking slide 83 at one end away from the umbrella-shaped protrusion 10 and is provided with a first push plate 87 located outside the side wall of the latching compartment 11.

[0033] The aforementioned limiting slide 81 is located below the adjusting slide 82, and the locking slide 83 is located outside the adjusting slide 82.

[0034] During installation: The operator moves the locking chamber 11 closer to the mounting ring seat 4. As it approaches the umbrella-shaped protrusion 10, the locking slide 84 first contacts the top of the umbrella-shaped protrusion 10. During this contact, the continuous pressure from the umbrella-shaped protrusion 10 causes the locking slide 84 to move outwards. Simultaneously, as the locking slide 84 slides outwards, the connecting rod 85 drives the adjusting slide plate 86 to slide upwards, compressing the adjusting spring 810. When the top of the umbrella-shaped protrusion 10 is fully embedded in the locking chamber 11, the locking slide 84 releases its pressure from the umbrella-shaped protrusion 10. At this point, the elasticity of the adjusting spring 810 causes the adjusting slide plate 86 to move downwards and reset. During the reset process, the connecting rod 85 pushes the locking slide 84 inwards within the limiting chamber 81, finally locking it in the lower locking position of the umbrella-shaped protrusion 10. This quickly completes the connection between the mounting ring seat 4 and the fixed base, improving the installation efficiency of the warning device.

[0035] When disassembly is required for inspection and maintenance: the staff pushes the first push plate 87 upward, the first push plate 87 drives the adjusting slide plate 86 to move upward against the elastic force of the adjusting spring 810. During the upward sliding process, the adjusting slide plate 86 drives the locking slide seat 84 to move outward through the connecting rod 85. When the adjusting slide plate 86 slides upward to the limit position, the locking slide seat 84 completely disengages from the umbrella-shaped boss 10. After the locking slide seat 84 is separated from the umbrella-shaped boss 10, the staff can easily remove the mounting ring seat 4 from the fixed base, which facilitates a comprehensive inspection and maintenance of the warning device and ensures its long-term stable operation.

[0036] Optionally, a locking assembly is provided inside the locking slide chamber 83. The locking assembly includes a slide groove opened vertically in the wall of the locking slide chamber 83 within the side wall of the snap-fit ​​chamber 11. A locking slide rod 88 is slidably disposed in the slide groove. An inclined guide is provided at one end of the locking slide rod 88 near the first push plate 87. A return spring is provided between the locking slide rod 88 and the slide groove. A second push plate 811 located outside the side wall of the snap-fit ​​chamber 11 is provided at the other end of the locking slide rod 88.

[0037] In this embodiment, when the umbrella-shaped protrusion 10 is fully embedded in the snap-fit ​​compartment 11 and forms a first engagement state with the locking slide seat 84, the angle of the warning component can be further adjusted by rotating the mounting ring seat 4 according to the installation environment requirements, thereby improving the flexibility and adaptability of the warning component installation.

[0038] When the locking slide 84 and the umbrella-shaped boss 10 are in the first engagement state, the first push plate 87 is pushed downwards, and the adjusting slide 86 moves downwards accordingly. After the adjusting slide 86 contacts the locking slide rod 88, it presses against the locking slide rod 88. Under the action of the inclined guide, the locking slide rod 88 moves away from the first push plate 87, and the return spring is compressed at the same time. When the adjusting slide 86 slides down to the bottom of the locking slide chamber 83, the adjusting slide 86 releases the pressure on the locking slide rod 88, and the return spring quickly springs back, causing the locking slide rod 88 to return to its original position. At this time, the locking slide rod 88 is located above the adjusting slide 86 and limits it. The first push plate 87 cannot move under the limitation of the locking slide rod 88, thus completing the second engagement state between the locking slide 84 and the umbrella-shaped boss 10, ensuring that the warning component is securely installed. In the initial state (i.e., before the mounting ring seat 4 moves close to the fixed ring seat), the adjusting slide 86 is located above the locking slide rod 88.

[0039] It should be noted that during the downward sliding of the first push plate 87 to the bottom of the locking slide chamber 83, the adjusting slide plate 86 moves downward accordingly. The connecting rod 85 drives the locking slide seat 84 to move further towards the umbrella-shaped boss 10 to lock the umbrella-shaped boss 10, thereby enhancing the locking effect. At the same time, the movement of the adjusting slide plate 86 also keeps the adjusting spring 810 under tension, improving the reliability of the second locking state and preventing loosening due to platform vibration or external impact.

[0040] When the warning component needs to be disassembled, first push the second push plate 811 to move the locking slide rod 88 away from the first push plate 87. When the locking slide rod 88 moves to fully enter the slide groove, the restriction of the locking slide rod 88 on the first push plate 87 and the constraint on the adjusting slide plate 86 are released. Then, under the action of the adjusting spring 810, the adjusting slide plate 86 automatically resets, thereby restoring the locking slide seat 84 and the umbrella-shaped boss 10 to the first engaged state. In the first engaged state, the operator can push the first push plate 87 upward to separate the locking slide seat 84 from the umbrella-shaped boss 10, thus unlocking the first engaged state. By setting a two-layer engaging structure, not only is the installation stability of the warning component improved, but the disassembly process is also simplified, ensuring quick and efficient maintenance operations, further enhancing its practicality and reliability.

[0041] Optionally, anti-slip protrusions are provided on the surfaces of both the first push plate 87 and the second push plate 811. The anti-slip protrusions are made of rubber, which can increase the friction between the operator's fingers and the object during operation, prevent fingers from slipping, and ensure safe and reliable operation.

[0042] Optionally, a first engaging platform 812 is provided at one end of the locking slide 84 near the umbrella-shaped boss 10, and a second engaging platform 101 is provided on the umbrella-shaped boss 10. In the second engaging state, the shapes of the first engaging platform 812 and the second engaging platform 101 match, and the raised stripes distributed on the first engaging platform 812 and the second engaging platform 101 interlock with each other, preventing the umbrella-shaped boss 10 from deflecting. This ensures that after the warning component is locked, even if subjected to severe vibration or impact, the warning component remains stable, further improving the durability and safety of the overall structure.

[0043] Optionally, the fixed base includes a fixed base plate 1 and an adjusting base ring 3. Four telescopic rods 2 are provided between the fixed base plate 1 and the adjusting base ring 3. The umbrella-shaped boss 10 is fixedly installed on the fixed base plate 1 and passes upward through the adjusting base ring 3.

[0044] In this embodiment, during the first engagement operation between the locking slide 84 and the umbrella-shaped boss 10, the bottom end of the locking chamber 11 presses against the adjusting bottom ring 3, causing the adjusting bottom ring 3 to slide downwards, and the telescopic rod 2 shortens accordingly, ensuring that the locking chamber 11 and the umbrella-shaped boss 10 fit tightly together, thus enhancing the initial engagement stability.

[0045] Optionally, the telescopic rod 2 includes a damping rod 21, which is disposed between the fixed base plate 1 and the adjusting bottom ring 3. A compression spring 22 is sleeved on the damping rod 21. During disassembly, the damping rod 21 reduces the rebound force of the compression spring 22 through its buffering effect, thereby allowing the adjusting bottom ring 3 to slowly push the snap-fit ​​compartment 11 away from the umbrella-shaped boss 10, avoiding damage or misoperation caused by rapid rebound, and ensuring a smooth and safe disassembly process.

[0046] Meanwhile, the compression spring 22 provides continuous elasticity during installation because it is in a compressed state, ensuring that the adjusting bottom ring 3 and the bottom of the snap-fit ​​compartment 11 always maintain tight contact, thereby effectively preventing loosening caused by vibration or external force, further enhancing the overall stability and reliability of the warning component, and ensuring efficient operation in various complex environments.

[0047] Optionally, the fixed base plate 1 is provided with threaded seats around its perimeter. The fixed base plate 1 can be securely fixed to the platform safety door by connecting the threaded seats with fastening bolts.

[0048] Optionally, the early warning component includes an early warning console 5, which is mounted on a mounting ring 4. A projector light 7 is rotatably mounted on the top of the console 5, and multi-colored LED beads 9 are arranged around the projector light 7. The multi-colored LED beads 9 can emit light signals of corresponding colors according to different warning levels, and the flashing frequency of the multi-colored LED beads 9 can also be adjusted according to the warning level. The projector light 7 can project information onto the platform floor or walls, clearly displaying the warning information, facilitating timely detection by passengers and enabling them to take appropriate measures, effectively improving the efficiency and effectiveness of station safety management.

[0049] Optionally, the warning system also includes an siren. The siren, in conjunction with multi-color LEDs 9, provides both audible and visual alerts, ensuring rapid delivery of warning information, enhancing emergency response capabilities, and protecting passenger safety.

[0050] Optionally, the warning component also includes a detector 6, which is located at the rear of the projection lamp 7. The detector 6 may include a sensor, such as an environmental sensor (temperature sensor, etc.), which monitors changes in the station's environment in real time. The alarm is activated when the sensor detects an anomaly, and it can also work with multi-color LED beads 9 to provide a dual audible and visual warning. The sensor may also be an image sensor, which captures images of the station in real time. If an anomaly is detected in the captured image, both the alarm and the multi-color LED beads 9 can be activated to issue a warning.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
