[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0022] like Figure 1-5 As shown, a sound-emitting device based on a flexible pressure-sensitive material floor sticker 1 includes a floor sticker 1 for placement on the ground and a warning device 2 installed on a guardrail. The floor sticker 1 consists of several sequentially adjacent trigger units 3, each corresponding to a warning device 2. Each trigger unit 3 includes a base layer 4 for fixed adhesion to the ground and a flexible pressure sensor 5 disposed above the base layer 4. A pressing layer 6, made of wear-resistant material, covers the flexible pressure sensor 5. The floor sticker 1 can be rolled up along the winding direction when stored. Static markings for indication are printed on the pressing layer 6, providing clear guidance to passengers. The floor sticker 1 can be easily laid out, and the warning device 2 sounds to remind passengers when they step on it. Made of flexible material, the floor sticker 1 can withstand long-term wear without damage, effectively improving the product's lifespan. Furthermore, the floor sticker 1 can be easily rolled up and stored, making it convenient to use.

[0023] The warning device 2 includes a base 7 and a signal processing unit, a power module, and a sound output tube mounted on the base 7. A housing 8 is fastened to the base 7, and the other side of the base 7 is mounted on the guardrail via a connecting assembly 9. When the signal processing unit detects the trigger state of the flexible pressure sensor 5, the sound output unit emits a preset sound prompt, such as "Please do not cross the yellow line." The signal processing unit receives the electrical signal from the flexible pressure sensor 5, performs amplification, filtering, and other processing, and identifies the trigger state of the flexible pressure sensor 5. The power module provides power to the entire device and can be powered by a battery or an external power source. The power module should have a stable voltage output to ensure the normal operation of the signal processing unit and the sound output unit, and issue a warning when the battery is low to remind staff to replace it in time. The warning device 2 also has an energy-saving mode, which can automatically enter a low-power mode during off-peak hours or when there are fewer passengers to reduce power consumption. When a passenger steps on the platform, the device immediately resumes normal operation to ensure the timeliness of the alert function. Through the one-to-one matching trigger unit 3 and warning device 2, the trigger unit 3, which is triggered only at the location where the passenger steps on the platform, can provide an alert through the corresponding warning device 2. When the platform door is open, if the passenger steps on the trigger unit 3, the warning device 2 will not be triggered.

[0024] The connecting assembly 9 includes a connecting seat 10 and a locking seat 11 mounted on the base 7. The connecting seat 10 is fixedly mounted on the base 7, and the locking seat 11 is detachably mounted on the base 7 via a snap-fit ​​structure 12. Multiple rotating blocks 13, sequentially connected end-to-end, are rotatably arranged between the connecting seat 10 and the locking seat 11. Adjacent rotating blocks 13 can rotate relative to each other via rotating plates 14 at both ends. Two rotating blocks 13 closest to the connecting seat 10 and the locking seat 11 are respectively rotatably mounted on the connecting seat 10 and the locking seat 11 via rotating plates 14. An elastic rope 15 for pressing the guardrail against the base 7 is provided between the two rotating blocks 13 closest to the connecting seat 10 and the locking seat 11. An arc-shaped plate 16 is fixedly mounted on the base 7, facing the elastic rope 15, and located between the connecting seat 10 and the locking seat 11. Both ends of the arc-shaped plate 16 are fixedly mounted on the base 7 via connecting plates 17. During installation, the rotating blocks 13 connected end to end surround the guardrail. The adjacent rotating blocks 13 can rotate freely and can be easily surrounded on guardrails of different diameters. The arc plate 16 abuts against the guardrail and the elastic rope 15 presses against the other side of the guardrail. The installation of the warning device 2 can be achieved by pressing the arc plate 16 and the elastic rope 15 against the two sides of the guardrail respectively.

[0025] The locking structure 12 includes two locking blocks 18 movably mounted on the locking seat 11. The base 7 has a notch 19 for inserting the locking block 18, and a slot 20 for engaging the locking block 18 within the notch 19. The locking seat 11 has a first cavity 21 at each end, and a pressure rod 22 is movably mounted within each first cavity 21. A channel 23 connecting the locking seat 11 to the first cavity 21 is provided at the end of the locking seat 11 facing the notch 19. The locking block 18 is fixedly mounted on the pressure rod 22 by a fixing plate 24 located within the channel 23. A spring 25 is provided within the first cavity 21 to drive the pressure rod 22 away from the other pressure rod 22, causing the locking block 18 to engage with the notch 19. The height of the notch 19 is the same as the height of the channel 23 and greater than the height of the locking block 18. The bottom of the first cavity 21 is provided with a second cavity 26, the diameter of which is smaller than the diameter of the first cavity 21. The bottom of the pressure rod 22 is fixedly provided with a guide rod 27 inserted into the second cavity 26. The spring 25 is located in the first cavity 21 and surrounds the outer periphery of the guide rod 27. The two slots 20 are arranged oppositely. During installation, by pressing the two levers 22, the locking blocks 18 are moved towards the other locking block 18 by the fixing plate 24 until the fixing plate 24 contacts the bottom of the channel 23. At this time, the locking blocks 18 are located in the notch 19 in the height direction. The locking seat 11 moves towards the notch 19 and makes the locking blocks 18 face the notch 19. When the locking seat 11 abuts against the base 7, the locking blocks 18 are completely located in the notch 19. After releasing the levers 22, the levers 22 move away from the second cavity 26 under the drive of the spring 25 and make the locking blocks 18 lock into the locking groove, thus completing the installation and fixation between the locking seat 11 and the base 7. During the movement of the levers 22, they are guided by the second cavity 26 and the guide rod 27 and limited by the fixing plate 24 located in the channel 23.

[0026] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the protection scope of this utility model.
