[0039] Example 1
[0040] like Figures 1-7 As shown, a sill clearance protection device includes a car door 1, a landing door 2, a car door sill 3, a landing door sill 4, a baffle plate 6, and a guide assembly 7. Door guide shoes 5 are installed at the bottom of the car door 1 and the landing door 2, and the door guide shoes 5 are located in the guide grooves 8 of the car door sill 3 and the landing door sill 4.
[0041] like Figure 5 As shown, the guide assembly 7 consists of a nut 12 and a double-ended stud 11. The nut 12 is installed at one end of the double-ended stud 11, and the other end is installed inside the car door sill 3. A notch is provided inside the car door sill 3, through which a baffle plate 6 passes and is placed inside the car door sill 3. The baffle plate 6 is equipped with an opening guide structure 9 and a closing guide structure 10.
[0042] When the car door 1 opens, it opens to both sides along the guide groove 8 of the car door sill 3. The door guide shoe 5 presses against the opening guide structure 9 on the baffle plate 6, causing the baffle plate 6 to extend from inside the car door sill 3 and block the gap between the car door sill and the landing door sill. When the car door 1 closes towards the center along the guide groove 8 of the car door sill 3. The door guide shoe 5 presses against the closing guide structure 10 on the baffle plate 6, causing the baffle plate 6 to retract into the car door sill 3. The guide assembly 7 restricts the displacement direction of the baffle plate.
[0043] Preferably, the opening guide structure and the closing guide structure are provided with ramps on their sides. When the door guide shoe 5 presses against the ramps, it provides a force to the baffle plate 6 in the direction of extending outward from the car door sill 3 or retracting into the car door sill 3, causing the baffle plate 6 to displace.
[0044] Preferably, such as Figure 6 and Figure 7 As shown, the baffle plate 6 is provided with a raised door opening guide structure 9 and a door closing guide structure 10. The raised design can provide a force perpendicular to the raised direction when the door guide shoe 5 contacts the guide structure on the baffle plate 6.
[0045] Example 2
