Technical Field

[0001] This invention relates to the field of elevator sill technology, specifically a novel self-adaptive seamless elevator sill. Background Technology

[0002] After the elevator door and the hall door are opened, there is a large gap between the sill of the elevator door and the sill of the hall door. Small items such as keys can easily fall into the gap as they slide on the floor. Pets can also easily get their feet stuck, which affects the passenger's riding experience. Summary of the Invention

[0003] The purpose of this invention is to provide a novel elevator adaptive seamless sill, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The novel elevator adaptive seamless sill includes a sill with a guide shoe groove. A movable component slides inside the guide shoe groove. An installation groove is provided in the sill and on one side of the guide shoe groove. A flipping device is provided inside the installation groove. The flipping device includes a connecting plate with a head end and a tail end. The tail end of the connecting plate is located inside the installation groove and rotatably connected to the installation groove. A first bevel gear is provided at the tail end of the connecting plate. A baffle is provided at the head end of the connecting plate. A base is provided inside the installation groove. A rotating shaft is rotatably connected to the base. One end of the rotating shaft is provided with a second bevel gear that meshes with the first bevel gear, and the other end of the rotating shaft is provided with a cylindrical gear. A through groove is provided on one side of the guide shoe groove in the sill. A fixed plate is provided on one side of the moving part. A sliding groove is provided on the upper surface of the fixed plate. It also includes a rack that meshes with the cylindrical gear. A locking block that cooperates with the sliding groove is provided at the lower end of the rack. A flexible side rod is symmetrically provided at one end of the locking block. A protrusion is provided on the outer surface of the side rod away from the other side rod. A slot that engages with the protrusion on the side rod is provided at one end of the sliding groove.

[0005] Preferably, when the upper surface of the baffle is at the same level as the upper surface of the sill after the baffle is rotated, the connecting plate abuts against the sill.

[0006] Preferably, when the two protrusions are engaged with the slot, the rack can drive the cylindrical gear to rotate.

[0007] Preferably, a compressible pad is provided on each side of the card block.

[0008] Preferably, the outer surface of the first end of the connecting plate is provided with an abutment block, and when the abutment block abuts against the outer surface of the sill, the upper surface of the baffle is perpendicular to the upper surface of the sill.

[0009] Preferably, the length of the baffle is not less than the width of the car door.

[0010] The beneficial effects of this invention are:

[0011] This device moves a baffle into the gap between the hall door sill and the car door sill as the hall door or car door opens, and removes the baffle from the gap as the hall door or car door is about to close. In other words, the baffle enters the gap earlier and leaves it later during the opening and closing process, maximizing its usability and effectively reducing the chances of small items like keys falling through the gap, as well as pets getting their feet stuck. This improves the safety of the sill and significantly enhances the passenger experience. Attached Figure Description

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-7 As shown, a novel adaptive seamless elevator sill includes a sill 1 with a guide shoe groove 2. A movable component 3 slides inside the guide shoe groove 2. An installation groove 4 is provided in the sill 1 and located on one side of the guide shoe groove 2. A flipping device is provided inside the installation groove 4. The flipping device includes a connecting plate 5 with a head end and a tail end. The tail end of the connecting plate 5 is located inside the installation groove 4 and rotatably connected to the installation groove 4. A first bevel gear 6 is provided at the tail end of the connecting plate 5, and a baffle 7 is provided at the head end of the connecting plate 5. A base 8 is provided inside the installation groove 4, and a rotating shaft 9 is rotatably connected to the base 8. A first bevel gear 6 is provided at one end of the rotating shaft 9. The second bevel gear 10 meshes with the gear 6 externally, and a cylindrical gear 11 is provided at the other end of the shaft 9. A through groove 12 is provided on one side of the guide shoe groove 2 in the sill 1. A fixed plate 13 is provided on one side of the moving part 3. A sliding groove 14 is provided on the upper surface of the fixed plate 13. It also includes a rack 15 that meshes with the cylindrical gear 11 externally. A locking block 16 that cooperates with the sliding groove 14 is provided at the lower end of the rack 15. A flexible side rod 17 is symmetrically provided at one end of the locking block 16. A protrusion 18 is provided on the outer surface of the side rod 17 away from the other side rod 17. A slot 19 that engages with the protrusion 18 on the side rod 17 is provided at one end of the sliding groove 14.

[0022] The sill 1 includes a sill 1 for the hall door and a sill 1 for the car door. This device can be installed on the sill 1 for the hall door and / or the car door, and both the hall door and the car door are double doors.

[0023] The bottom of the movable part 3 is a guide shoe that is slidably connected to the guide shoe groove 2. The upper part of the movable part 3 is a hall door or car door. The guide shoe is set at the lower end of the hall door or car door. The lower end of the hall door or car door is partially located in the guide shoe groove 2. The fixing plate 13 can be installed on one side of the guide shoe or on one side of the hall door or car door. When the movable part 3 slides in the guide shoe groove 2 of the sill 1, the movable part 3 can drive the fixing plate 13 to move synchronously. At the same time, the fixing plate 13 moves in the through groove 12 on the sill 1.

[0024] When rack 15 moves, it meshes with cylindrical gear 11, causing cylindrical gear 11 to rotate. Cylindrical gear 11 then rotates shaft 9 synchronously, which in turn rotates the second bevel gear 10. The second bevel gear 10 meshes with the first bevel gear 6, causing the first bevel gear 6 to rotate. The first bevel gear 6 then rotates connecting plate 5, which in turn rotates baffle 7. The rotation direction of baffle 7 is controlled by controlling the direction of rack 15's movement. Figure 3 From the perspective of [the user], when the car door is opened, the baffle 7 will rotate clockwise, and when the car door is closed, the baffle 7 will rotate counterclockwise.

[0025] Since the locking block 16 slides within the groove 14 of the fixed plate 13, when the fixed plate 13 moves with the moving part 3, and when the locking block 16 is not obstructed by external force, the locking block 16 will move with the fixed plate 13, and the position of the locking block 16 and the fixed plate 13 remains relatively stationary. However, when the cylindrical gear 11 and the rack 15 come into contact with each other, due to the obstruction of external force, when the fixed plate 13 moves, the locking block 16 will not be able to move with the fixed plate 13 in time. Only when one end of the locking block 16 abuts against one end of the groove 14 can the locking block 16 continue to move synchronously with the fixed plate 13.

[0026] The side rod 17 and the protrusion 18 can be integrally injection molded from plastic or formed by bending metal sheet. The side rod 17 can be directly fixed to the locking block 16 by welding, threaded connection or adhesive bonding. When the locking block 16 is pushed towards the slot 19, the locking block 16 drives the side rod 17 and the protrusion 18 to move towards the slot 19. One end of the protrusion 18 first enters the slot 19, and at the same time the side rod 17 bends. When the protrusion 18 is fully engaged with the slot 19, the locking block 16 cannot continue to move towards the slot 19 in the slide groove 14, and the locking block 16 remains relatively stationary with the fixing plate 13. When the locking block 16 is pushed in another direction, the locking block 16 moves away from the slot 19. When the pushing force is greater than the engagement force between the protrusion 18 and the slot 19, the side rod 17 bends, the protrusion 18 comes out of the slot 19, and the locking block 16 moves in the slide groove 14 of the fixing plate 13 under the action of the pushing force.

[0027] Furthermore, after the baffle 7 rotates, when the upper surface of the baffle 7 is at the same level as the upper surface of the sill 1, the connecting plate 5 abuts against the sill 1. By abutting against the sill 1, the baffle 7 can be prevented from rotating further, thus preventing the upper surface of the baffle 7 from being higher than the upper surface of the sill 1. This prevents the formation of a step between the baffle 7 and the sill 1, thereby improving the safety of elevator use.

[0028] Furthermore, when the two protrusions 18 are engaged with the slots 19, the rack 15 can drive the cylindrical gear 11 to rotate. When both the elevator door and the hall door are closed, the protrusions 18 and the slots 19 are fully engaged, and the end of the rack 15 closest to the slots 19 is just meshed with the cylindrical gear 11. When the elevator door and the hall door are open, the moving part 3 drives the fixed plate 13 to move within the through groove 12 on the sill 1. Through the cooperation of the protrusions 18 and the slots 19, the fixed plate 13 can also drive the rack 15 to move. The position of the spur gear 11 does not move with the fixed plate 13. Therefore, there is a relative displacement between the rack 15 and the spur gear 11. Through the meshing between the two, the spur gear 11 rotates. The rotation of the spur gear 11 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the second bevel gear 10 to rotate, and also drives the first bevel gear 6, the connecting plate 5, and the baffle 7 to rotate. When the connecting plate 5 abuts against the sill 1, the connecting plate 5 can no longer rotate, which also means that the spur gear 11 can no longer rotate. At this time, the spur gear 11 also cannot move with the fixed plate 13. The fixed plate 13 continues to move in the same direction as the moving part 3, causing the slot 19 to press against the protrusion 18. Simultaneously, the side rod 17 deforms, causing the protrusion 18 and side rod 17 to disengage from the slot 19. As the fixed plate 13 continues to move, and when the end of the slide 14 furthest from the slot 19 abuts against the end of the locking block 16, the hall door or elevator door is fully opened. At this time, the cylindrical gear 11 and the rack 15 remain engaged. When the hall door or elevator door closes, the fixed plate 13 moves in the opposite direction along with the moving part 3. The friction between the rack 15 and the cylindrical gear 11, and between the first bevel gear 6 and the second bevel gear 10, is greater than the friction between the locking block 16 and the sliding groove 14. This prevents the rack 15 from moving with the fixing plate 13. When the protrusion 18 and one end of the slot 19 abut against each other, the protrusion 18 enters the slot 19, and the rack 15 moves synchronously with the fixing plate 13. At this time, the rack 15 drives the cylindrical gear 11 to rotate, which in turn drives the connecting plate 5 and the baffle 7 to rotate in the opposite direction, and the baffle 7 is stored under the mounting groove 4.

[0029] Furthermore, compressible pads 20 are provided on both sides of the locking block 16. The pads 20 can prevent the rack 15 and the locking block 16 from shaking in the groove 14 of the fixing plate 13, maintaining the stability of the rack 15. At the same time, the friction between the pads 20 and the fixing plate 13 is low, so as to reduce the impact on the movement of the locking block 16.

[0030] Furthermore, the outer surface of the first end of the connecting plate 5 is provided with an abutment block 21. When the abutment block 21 abuts against the outer surface of the sill 1, the upper surface of the baffle 7 is perpendicular to the upper surface of the sill 1. The rotation angle of the baffle 7 can be controlled by the abutment block 21, so as to facilitate the control of the tooth ratio between the rack 15 and the cylindrical gear 11 according to the rotation angle of the baffle 7. When the cylindrical gear 11 and the rack 15 are in the state from the initial meshing to the disengagement, the baffle 7 can rotate 90°.

[0031] Furthermore, the length of the baffle 7 is not less than the width of the car door, so as to better seal the gap between the hall door sill 1 and the car door sill 1.

[0032] Working principle: When the hall door or car door is opened, the moving part 3 drives the fixed plate 13 to move. Since the protrusion 18 is engaged with the slot 19 at this time, the rack 15 can move with the fixed plate 13. The rack 15 rotates with the cylindrical gear 11, causing the rotating shaft 9 to rotate, and finally driving the baffle 7 from below the mounting groove 4 to the gap between the hall door sill 1 and the car door sill 1. When the upper surface of the baffle 7 is on the same plane as the upper surface of the sill 1, the baffle 7 can no longer rotate. At this time, the cylindrical gear 11 can no longer rotate, and the rack 15 can no longer move. The fixed plate 13 continues to move in the original direction, causing the protrusion 18 to move from the mounting groove 4 to the car door sill 1. When the card block 16 disengages from the slot 19, and one end of the card block 16 contacts the end of the slide groove 14 away from the slot 19, the hall door or car door is fully opened, and the moving part 3 stops moving. When the hall door or car door is closed, the moving part 3 moves and drives the fixed plate 13 to move. When the fixed plate 13 moves, the rack 15 does not follow the fixed plate 13 until one end of the protrusion 18 abuts against the slot 19 and enters the slot 19. During this process, the rack 15 follows the fixed plate 13 again. The rack 15 meshes with the cylindrical gear 11, causing the cylindrical gear 11 to rotate in the opposite direction, and finally drives the baffle 7 to move in the opposite direction, retracting the baffle 7 to the position below the mounting groove 4.

[0033] This device can move the baffle 7 into the gap between the hall door sill 1 and the car door sill 1 as the hall door or car door opens, and remove the baffle 7 from the gap as the hall door or car door is about to close. In other words, the baffle 7 enters the gap earlier and leaves the gap later during the opening and closing process of the hall door or car door, thereby maximizing the usage time of the baffle 7 during the opening and closing process of the hall door or car door. This can effectively reduce the occurrence of small items such as keys falling into the gap, reduce the occurrence of pets getting their feet stuck, improve the safety of the sill 1, and greatly enhance the passenger riding experience.
