[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] Please see the appendix Figure 1 To be continued Figure 5This invention discloses a novel elevator structure, comprising:

[0035] Elevator shaft 1, sealing seat 2 installed at the bottom of elevator shaft 1, car 3 installed inside elevator shaft 1, guide blocks 4 installed on the left, back and right sides of car 3, guide rails 5 opened on the left, back and right sides of the inner wall of elevator shaft 1, and the guide rails 5 are slidably connected to the guide blocks 4, and floor doors 6 installed outside elevator shaft 1.

[0036] The sealing assembly includes a first connecting frame 7 installed at the bottom of the car 3, and at least four sets of sealing plates 9 are provided inside the first connecting frame 7. The sealing plates 9 are connected to the first connecting frame 7 through a driving part, so that the driving part drives the sealing plates 9 to unfold outward, sealing the space at the bottom of the car 3 and isolating the internal air from the external air. When the driving part drives the sealing plates 9 to unfold, it can effectively and quickly seal the bottom of the car 3, so that the bottom of the car 3 and the elevator shaft 1 are sealed, and the car 3 moves downward in the elevator shaft 1 like a piston. Since the sealing plates 9 seal the bottom of the car 3, the falling speed of the car 3 can be effectively reduced when the car 3 moves downward like a piston, and buffer protection is provided when the car 3 falls.

[0037] The sealing plate 9 has an L-shaped structure, with through slots 10 at both ends of the L-shape. These slots 10 are staggered, allowing at least four sets of sealing plates 9 to interlock in pairs via the through slots 10. An airflow regulating section is also provided inside the sealing plate 9. The through slots 10 allow the sealing plates 9 to interlock in pairs, forming a flat surface and sealing the sealing block against the elevator shaft 1, thus isolating the air at the bottom of the car 3 from the outside air. A set of slide rails 11 are staggered on the overlapping surfaces of the through slots 10, and sliders 12 are slidably connected within each slide rail 11. The side of the slider 12 furthest from the slide rail 11 is fixedly connected to the surface of another through slot 10. The slide rail 11 and slider 12... A first spring 13 is installed between the slider 12 and the slide rail 11. When the sealing plate 9 is unfolded outward, the slider 12 slides within the slide rail 11. Under the action of the elastic force of the first spring 13, when the sealing plate 9 is retracted inward to restore itself, the elastic contraction force of the first spring 13 controls the movement of the sealing plate 9, causing the sealing plate 9 to reset. A clearance groove 21 is provided in the sealing plate 9, and a connecting rod 22 is provided in the clearance groove 21. The two ends of the connecting rod 22 are fixedly connected to the inner wall of the first connecting frame 7. The first connecting frame 7 is fixed by the connecting rod 22, and the movement of the sealing plate 9 is limited by the clearance groove 21.

[0038] Please see the appendix Figure 3 To be continued Figure 6The drive unit includes limiting rails 15, which are adapted to the number of sealing plates 9, and are installed in the first connecting frame 7. Support plates 16 are installed on the side of each limiting rail 15 adjacent to it. A rotating disk 17 is provided on the outside of the support plate 16, and guide grooves 18 are formed around the inside of the rotating disk 17. Sliding rods 19 are slidably connected within each guide groove 18, and the sliding rods 19 are fixedly connected to the support plates 16. A motor 20 is installed at the bottom of the second connecting frame 8, and the output shaft of the motor 20 is fixedly connected to the rotating disk 17. When the drive unit drives the sealing plates 9 to unfold outwards, the drive motor 20 rotates, causing the rotating disk 17 to rotate synchronously. Through the slidable connection between the guide grooves 18 and the sliding rods 19, the guide grooves 18 guide the sliding rods 19 outwards, causing the support plates 16 to drive the limiting rails 15 outwards. The sealing plate 9 is pushed to move and unfold, sealing it against the inner wall of the elevator shaft 1. This isolates the air at the bottom of the car 3 from the outside air of the elevator shaft 1, temporarily preventing air from escaping from the bottom of the car 3. When the car 3 is falling, the sealing plate 9 blocks the airflow between itself and the elevator shaft 1, reducing the falling speed of the car 3 and providing cushioning protection. The side of the sealing plate 9 that contacts the limiting rail 15 has a sliding groove 14, which is slidably connected to the limiting rail 15. When the limiting rail 15 moves outward and unfolds, the sliding connection between the limiting rail 15 and the sliding groove 14 pushes the sealing plate 9 outward, thus sealing it against the inner wall of the elevator shaft 1, isolating the air at the bottom of the car 3 from the outside air and preventing it from escaping.

[0039] Please see the appendix Figure 3 To be continued Figure 5 and attached Figure 7 The airflow regulating unit includes an air inlet 23 located inside the sealing plate 9 near a right angle, and a baffle 24 is provided inside the air inlet 23. A connecting groove is also provided inside the air inlet 23, and a first electric push rod 25 is installed in the connecting groove. The telescopic end of the first electric push rod 25 is fixedly connected to the baffle 24. The baffle 24 is moved by the first electric push rod 25 to control the size of the air inlet 23, thereby changing the falling speed of the car 3. In the implementation process, the positioning device on the car 3 and the floor door 6 in the prior art can be used to send an electronic signal to the first electric push rod 25 to control the falling speed of the car 3, so that the door on the car 3 is aligned with the floor door 6, so as to avoid the dangerous situation of the car 3 being between two floors.

[0040] Please see the appendix Figure 6The mechanical locking assembly includes a second connecting frame 8 installed at the bottom of the first connecting frame 7, and the second connecting frame 8 is fixedly connected to the guide block 4. Two sets of guide blocks 4 on the left and two sets on the right are slidably connected to first insert rods 29. A pushing part is provided between the first insert rod 29 and the second connecting frame 8. The pushing part includes a swing arm 26 with a bearing connected to the second connecting frame 8, and both ends of the swing arm 26 are rotatably connected to a support rod 27 via a rotating shaft. The end of the support rod 27 away from the swing arm 26 is rotatably connected to a push plate 28 via a rotating shaft, and the push plate 28 is fixedly connected to the first insert rod 29. A second spring 30 is provided on the outside of the insertion rod 29, and one end of the second spring 30 is fixedly connected to the push plate 28, and the other end is fixedly connected to the inner wall of the left and right guide blocks 4. A gear 35 is installed at the bottom of the swing arm 26, and a rack plate 36 is meshed with the outside of the gear 35. A second electric push rod 37 is installed at one end of the rack plate 36, and the second electric push rod 37 is fixedly connected to the second connecting frame 8. When the positioner on the car 3 and the floor door 6 in the prior art sends a signal to the first electric push rod 25, the second electric push rod 37 moves synchronously, controlling the rack plate 36 to move. The rack plate 36 and gear 35 mesh together to control the rotation of the swing arm 26, causing the support rod 27 to push and press the push plate 28. Simultaneously, the guide block 31 moves synchronously, controlling the first insertion rod 29 and the second insertion rod 32 to move outwards synchronously, thus engaging the first insertion rod 29 and the second insertion rod 32 with the slot 39 to lock the car 3. The second insertion rod 32 is slidably connected within the two sets of guide blocks 4 on the back, and one end of the second insertion rod 32 is rotatably connected to a roller 33 via a rotating shaft. A guide block 31 is installed at one end of the push plate 28, and the guide... The guide block 31 is inclined, and the outer surface of the roller 33 contacts the guide block 31. Through the contact between the roller 33 and the guide block 31, the second insertion rod 32 can be better driven to move and engage with the slot 39. A third spring 34 is also provided on the outside of the second insertion rod 32. One end of the third spring 34 is fixedly connected to the second insertion rod 32, and the other end is fixedly connected to the inner wall of the back guide block 4. A locking buffer part is provided between the first insertion rod 29 and the second insertion rod 32 and the guide rail 5 to mechanically lock and position the car 3, so that the car 3 stops stably and increases safety.

[0041] Please see the appendix Figure 8 To be continued Figure 10The locking buffer includes a groove formed within the guide rail 5, and a buffer plate 38 is slidably connected within the groove. The buffer plate 38 has several sets of slots 39 inside, and these slots 39 engage with the first insert rod 29 and the second insert rod 32. A connecting block 40 is located below the buffer plate 38 and is fixedly connected to the guide rail 5. Limiting rods 41 are slidably connected to both sides of the connecting block 40, and buffer springs 42 are provided on the outside of each limiting rod 41. The buffer springs 42 are made of steel, which has high hardness, good toughness, and strong elastic recovery ability, and can withstand [the stress / damage]. Due to the large deformation and pressure, one end of the buffer spring 42 is fixedly connected to the buffer plate 38, and the other end is fixedly connected to the connecting block 40. The inner liner 43 is also glued in the groove, and the inner liner 43 is in contact with the buffer plate 38. The inner liner 43 is made of rubber. When the buffer plate 38 moves, the friction of the inner liner 43 decelerates the buffer plate 38 and provides secondary buffering. By using the inner liner 43, the buffer plate 38, and the buffer spring 42 to buffer the first insert rod 29 and the second insert rod 32 with the slot 39, the car 3 can be smoothly stopped.
