Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator swing door. Background Technology

[0002] In today's urban environment filled with high-rise buildings, elevators, as key equipment for vertical transportation of people and goods, have their overall operational quality and passenger experience directly affected by the performance of their swing door systems. With the rapid development of the construction industry and people's increasing demands for quality of life, traditional elevator swing doors have gradually revealed many technical problems that urgently need to be solved in practical applications, making it difficult to meet the needs of modern elevator technology development.

[0003] Traditional elevator swing doors mostly use simple single or double-leaf mechanical structures with relatively simple and crude drive methods. In terms of drive stability, the common mode of relying on a single motor directly connected to the door shaft cannot accurately control the opening and closing speed and force of the door. This can easily lead to jamming and shaking during the opening or closing process, which not only affects the smoothness of passengers entering and exiting the elevator, but also accelerates the wear and tear of the door and related connecting parts over a long period of time due to irregular forces, reducing the service life of the equipment, increasing maintenance costs and elevator downtime, and causing inconvenience to vertical transportation within the building.

[0004] Sealing is also a major weakness of traditional elevator swing doors. Ordinary door gap designs rely solely on simple rubber strips, which are insufficient to handle airflow changes during elevator operation, pressure differences between the inside and outside of the car, and the intrusion of dust and noise. When the elevator is running at high speed, the pressure difference between the inside and outside of the car causes a large amount of air to rush in or leak through the door gaps, producing annoying drafts and allowing dust to easily enter the car, polluting the interior environment. In terms of noise insulation, the rudimentary sealing method cannot effectively block external noise from entering the car, posing a challenge to creating a quiet and comfortable riding environment for passengers, especially in places with high environmental noise requirements, such as high-end office buildings, hotels, and hospitals, seriously affecting the user experience.

[0005] Furthermore, traditional elevator swing doors suffer from low levels of ease of operation and intelligence. In daily use, the door's opening and closing response is slow; after a passenger presses the open button, there is often a considerable wait before the door begins to move. When closing, if an obstacle is encountered, the lack of sensitive sensing and automatic adjustment mechanisms may cause the door to close forcibly, potentially trapping people or objects, posing a significant safety hazard. Moreover, traditional elevator swing doors are not designed for deep integration with modern elevator control systems, making it difficult to achieve intelligent functions such as remote monitoring and fault warnings, which is detrimental to elevator maintenance, management, and efficient operation. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an elevator swing door, thereby solving the above-mentioned technical defects.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An elevator swing door includes:

[0009] The frame has an opening in the middle, and a first swing door and a second swing door are movably disposed inside the opening. The first and second swing doors are driven by a drive assembly, and the first and second swing doors move in opposite directions. A sealing assembly is also provided inside the first and second swing doors. The sealing assembly includes a first sealing element disposed inside the first swing door and a second sealing element disposed inside the second swing door. When the first and second swing doors come into contact, the first and second sealing elements will press against each other to seal the door.

[0010] In one or more embodiments of this utility model, the first sealing member and the second sealing member have the same mechanism and are symmetrical; the first sealing member is vertically fixed to the inner edge of the first swing door, and the second sealing member is vertically disposed at the inner edge of the second swing door; the first sealing member includes a U-shaped body, a support plate is fixed inside the U-shaped body, and the arc of the U-shaped body faces outward.

[0011] In one or more embodiments of this utility model, the first sealing element and the second sealing element are made of rubber.

[0012] In one or more embodiments of this utility model, the drive assembly includes two fixed plates fixed to a frame. A drive wheel and a driven wheel are respectively fixed to the fixed plates via a rotating shaft. A drive belt is fitted onto the drive wheel and the driven wheel. A first connecting plate is fixed to the upward moving end of the drive belt. A transverse guide rail is also fixed to the inner side of the upper end of the frame. The guide rail is located above the first swing door and the second swing door. A first drive wheel is fixed to the inner side of the first connecting plate via a rotating shaft. The first drive wheel can slide on the guide rail. The lower end of the first connecting plate is fixed to the upper end of the second swing door. The drive wheel is driven by a drive motor.

[0013] In one or more embodiments of this utility model, a second connecting plate is fixed to the downward moving end of the drive belt, a connecting seat is fixed to the lower side of the second connecting plate, the connecting seat is fixed to the upper end of the first swing door, a second drive wheel is fixed to the inner side of the connecting seat via a rotating shaft, and the second drive wheel can slide on the guide rail; the connecting seat also has an upwardly extending extension plate, a third drive wheel is fixed to the inner side of the extension plate via a rotating shaft, and the third drive wheel can slide on the guide rail.

[0014] In one or more embodiments of this utility model, a connecting piece is fixed to the upper end of the second sealing member, and a fourth driving wheel is fixed to the inner side of the upper end of the connecting piece via a rotating shaft. A square plate is fixed to the outer side of the first connecting plate, and an arc-shaped piece is fixed to the outer side of the square plate. The fourth driving wheel can slide within the arc-shaped piece. When the fourth driving wheel slides to a certain position within the arc-shaped piece, it will drive the second sealing member to move upward.

[0015] In one or more embodiments of this utility model, a plurality of vertical limiting shafts are fixed on the inner side of the second swing door, and a plurality of vertical limiting elongated holes are provided on the second sealing member, with the limiting shafts respectively located in the limiting elongated holes.

[0016] The beneficial effects of this utility model are:

[0017] This utility model features a first and second sealing element that are not only structurally identical and symmetrically distributed, precisely fitting the door gap. Made of rubber, which exhibits excellent flexibility, the sealing element adapts to deformation when the door is closed, tightly filling the gap and effectively blocking airflow exchange between the inside and outside of the elevator car. This eliminates wind noise caused by pressure differences during high-speed operation. Simultaneously, its powerful sealing ability firmly keeps dust and noise outside the car, creating a quiet and clean riding environment for passengers. This overcomes the shortcomings of traditional elevator swing doors in terms of sealing. At the end of the closing process, the fourth drive wheel of the upper connecting piece of the second sealing element cooperates with the arc-shaped piece on the outer square plate of the first connecting plate, causing the second sealing element to slightly adjust upwards. This further compresses the first and second sealing elements, enhancing the sealing effect and ensuring a tighter seal for the elevator car. The sealing provides ultimate protection, a sophisticated sealing mechanism not found in traditional elevator swing doors. This invention employs a belt drive core consisting of a drive wheel, a driven wheel, and a drive belt, combined with a fixed plate on the frame, forming a stable power transmission architecture. When the drive motor starts, power is transmitted precisely and smoothly through this system, effectively avoiding the jamming and shaking problems of the traditional single-motor direct-drive door shaft mode. Through the first and second connecting plates connected to the upper and lower moving ends of the drive belt, and their ingenious connection with the first and second swing doors, it is ensured that the two doors can strictly follow the set speed and trajectory to achieve stable reverse synchronous opening and closing, greatly extending the service life of the door body and connecting components, reducing maintenance frequency, and ensuring the smooth flow of vertical elevator traffic.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] In this embodiment, as Figures 1 to 2 As shown, an elevator swing door includes a frame 1 with an opening in the middle. A first swing door 2 and a second swing door 3 are movably disposed inside the opening. The first swing door 2 and the second swing door 3 are driven by a drive assembly, and the movement directions of the first swing door 2 and the second swing door 3 are opposite. A sealing assembly is also provided inside the first swing door 2 and the second swing door 3. The sealing assembly includes a first sealing element 4 disposed inside the first swing door 2 and a second sealing element 5 disposed inside the second swing door 3. When the first swing door 2 and the second swing door 3 come into contact, the first sealing element 4 and the second sealing element 5 will press against each other to seal.

[0022] In this embodiment, the elevator swing door uses frame 1 as the main supporting structure, which is embedded in the elevator entrance and provides the foundation for the door system. An opening is formed in the middle of frame 1, and the first swing door 2 and the second swing door 3 on the inner side are driven by a drive assembly, moving in opposite directions. When the elevator opens or closes, they move towards or away from each other, completing the opening and closing of the doorway and providing passage for passengers. Sealing components are located inside the first swing door 2 and the second swing door 3. A first seal 4 is vertically fixed to the inner edge of the first swing door 2, and a second seal 5 is vertically positioned on the inner edge of the second swing door 3; the two components have identical structures and are symmetrically distributed. When the elevator door closes, the first seal 4 and the second seal 5 collide and press together, forming a sealing barrier that blocks airflow, dust, and noise from inside and outside the elevator, creating a safe environment in the elevator car.

[0023] In one or more embodiments of this utility model, the first sealing member 4 and the second sealing member 5 have the same mechanism and are symmetrical; the first sealing member 4 is vertically fixed to the inner edge of the first swing door 2, and the second sealing member 5 is vertically disposed at the inner edge of the second swing door 3; the first sealing member 4 includes a U-shaped body, a support plate is fixed inside the U-shaped body, and the arc of the U-shaped body faces outward.

[0024] Taking the first sealing element 4 as an example, it consists of a U-shaped body with an internal support plate to enhance overall strength and prevent deformation under pressure. The U-shaped body has an outward arc for easy installation and disassembly, ensuring the stability and reliability of the sealing assembly.

[0025] In one or more embodiments of this utility model, the first sealing member 4 and the second sealing member 5 are made of rubber.

[0026] In this embodiment, the first seal 4 and the second seal 5 are made of rubber. Rubber has good flexibility and can deform fully when the door is closed, fitting tightly with the seal on the opposite side; it also has strong wear resistance and aging resistance, and can maintain sealing performance for a long time under frequent opening and closing of elevator doors, extending the life of the sealing components, reducing maintenance frequency, and lowering operating costs.

[0027] In one or more embodiments of this utility model, the driving assembly includes two fixed plates 6 fixed to the frame 1. A driving wheel 7 and a driven wheel 8 are respectively fixed on the fixed plates 6 via rotating shafts. A driving belt 9 is sleeved on the driving wheel 7 and the driven wheel 8. A first connecting plate 10 is fixed to the upward moving end of the driving belt 9. A transverse guide rail 11 is also fixed to the inner side of the upper end of the frame 1. The guide rail 11 is located above the first swing door 2 and the second swing door 3. A first driving wheel 12 is fixed to the inner side of the first connecting plate 10 via rotating shafts. The first driving wheel 12 can slide on the guide rail 11. The lower end of the first connecting plate 10 is fixed to the upper end of the second swing door 3. The driving wheel 7 is driven by a driving motor.

[0028] In this embodiment, the drive assembly is the "power heart" for the operation of the elevator swing door. Two fixed plates 6 on the frame 1 fix the driving wheel 7 and the driven wheel 8, and the drive belt 9 is looped between them to form a primary transmission link. When the driving wheel 7 is driven to rotate by the drive motor, the drive belt 9 transmits power.

[0029] In one or more embodiments of this utility model, a second connecting plate 13 is fixed to the downward moving end of the drive belt 9, a connecting seat 14 is fixed to the lower side of the second connecting plate 13, the connecting seat 14 is fixed to the upper end of the first swing door 2, a second drive wheel 15 is fixed to the inner side of the connecting seat 14 via a rotating shaft, and the second drive wheel 15 can slide on the guide rail 11; the connecting seat 14 also has an upwardly extending extension plate, a third drive wheel 16 is fixed to the inner side of the extension plate via a rotating shaft, and the third drive wheel 16 can slide on the guide rail 11.

[0030] In this embodiment, the first connecting plate 10 is fixed to the upward moving end of the drive belt 9, and the guide rail 11 on the inner side of the upper end of the frame 1 guides the moving parts. The first drive wheel 12 on the inner side of the first connecting plate 10 can slide on the guide rail 11, and its lower end is fixed to the upper end of the second swing door 3, driving the second swing door 3 to open upward.

[0031] The second connecting plate 13 is fixed to the downward moving end of the drive belt 9. The connecting seat 14 on the lower side of the second connecting plate 13 is fixed to the upper end of the first swing door 2. The second drive wheel 15 on the inner side of the connecting seat 14 can slide on the guide rail 11, so that the first swing door 2 opens downward and the two doors move in opposite directions synchronously.

[0032] The third drive wheel 16 on the inner side of the extension plate extending upward from the connecting seat 14 can also slide on the guide rail 11. The multiple drive wheels and the guide rail work together to ensure that the door opens and closes accurately and smoothly.

[0033] In one or more embodiments of this utility model, a connecting piece 17 is fixed to the upper end of the second sealing member 5, and a fourth driving wheel 18 is fixed to the inner side of the upper end of the connecting piece 17 via a rotating shaft. A square plate 19 is fixed to the outer side of the first connecting plate 10, and an arc-shaped piece 20 is fixed to the outer side of the square plate 19. The fourth driving wheel 18 can slide within the arc-shaped piece 20. When the fourth driving wheel 18 slides to a certain position within the arc-shaped piece 20, it will drive the second sealing member 5 to move upward.

[0034] In this embodiment, during the final stage of elevator door closing, the fourth drive wheel 18 is fixed to the inner side of the connecting piece 17 at the upper end of the second seal 5 via a rotating shaft, and an arc-shaped piece 20 is fixed to the outer side of the square plate 19 on the outer side of the first connecting plate 10. The fourth drive wheel 18 can slide within the arc-shaped piece 20. When the door is about to close completely, the fourth drive wheel 18 slides to a specific position, causing the second seal 5 to move upward a short distance, making the first seal 4 and the second seal 5 more tightly pressed together, thus improving the sealing effect.

[0035] In one or more embodiments of this utility model, a plurality of vertical limiting shafts are fixed on the inner side of the second swing door 3, and a plurality of vertical limiting elongated holes are provided on the second sealing member 5, with the limiting shafts respectively located in the limiting elongated holes.

[0036] In this embodiment, several vertical limiting shafts are fixed inside the second swing door 3, and several vertical limiting elongated holes are opened on the second sealing member 5. The limiting shafts are located inside the limiting elongated holes to prevent the second sealing member 5 from shifting and shaking, ensuring that its position is correct during the door movement and ensuring the reliability of the elevator swing door system.

[0037] Both ends of the guide rail are fixed with stop seats 21, and the first connecting plate 10 and the extension plate are fixed with fixing seats 22. The fixing seats 22 are fixed with stop posts 23, and the stop posts 23 are respectively corresponding to the stop seats 21.

[0038] Working principle of this utility model:

[0039] When the elevator's swing doors are in operation, upon reaching the target floor and triggering the door opening signal, the drive motor starts, causing the drive wheel 7, fixed to the fixed plate 6 on the frame 1, to rotate. The drive belt 9, fitted between the drive wheel 7 and the driven wheel 8, rotates accordingly. The upward movement of the drive belt 9 moves the first connecting plate 10, and the first drive wheel 12 inside the first connecting plate 10 slides stably along the guide rail 11 on the upper inner side of the frame 1. Simultaneously, the lower end of the first connecting plate 10 pushes the second swing door 3 upward. At the same time, the downward movement of the drive belt 9 moves the second connecting plate 13, and the connecting seat 14 fixed to the lower side of the second connecting plate 13 causes the first swing door 2 to open downward. The second drive wheel 15 inside the connecting seat 14 also slides smoothly on the guide rail 11, and the third drive wheel 16 on its extension plate also assists in movement along the guide rail 11. The two doors continue to move in opposite directions until fully open, facilitating passenger entry and exit. When the elevator is about to leave, a door-closing signal is triggered, the drive motor reverses, and the components operate in reverse order, causing the first swing door 2 and the second swing door 3 to move towards each other. As the closing nears completion, the arc-shaped piece 20 on the outer square plate 19 of the first connecting plate 10 interacts with the fourth drive wheel 18 on the upper connecting piece 17 of the second seal 5, causing the second seal 5 to move upward a short distance, allowing the first seal 4 and the second seal 5 to press tightly together, completing the seal, and the elevator can then depart normally.
