Description

Technical Field

[0001] This application relates to the field of elevator technology, and more particularly to an elevator guard structure. Background Technology

[0002] With rapid urbanization, elevators have become an indispensable vertical transportation tool in modern high-rise buildings. The operational safety of elevators directly affects the safety of passengers and goods transported; therefore, the design of elevator safety structures plays a crucial role in elevator systems. Existing elevator safety structures primarily use fixed safety doors to close and protect the elevator entrance and exit. Their operation typically relies on simple mechanical structures and manual operation. In some special scenarios, such as when the elevator is not fully connected to the floor or when the entrance / exit status needs to be temporarily changed, this design can easily cause inconvenience and even affect the safety of elevator operation.

[0003] However, in existing technologies, traditional guarding structures generally suffer from rigid design, failing to flexibly adapt to the dynamic adjustment requirements of guarding doors during elevator-floor connections. For example, when an elevator needs to simultaneously provide upper and lower guarding functions under certain circumstances, existing guarding structures often require manual disassembly or modification of the guarding devices, increasing operational complexity and potentially causing component wear or damage due to structural adjustments. Furthermore, some guarding doors fail to adequately consider space utilization when closing or opening, leading to potential jamming during operation and consequently affecting elevator-floor connection efficiency and operational safety.

[0004] To address the aforementioned issues, it is necessary to propose an elevator guard structure that can flexibly realize the independent and coordinated operation of the upper and lower guard doors, optimize space utilization efficiency, and thus improve the safety and ease of operation of the elevator. Utility Model Content

[0005] The purpose of this application is to overcome the shortcomings of the prior art and propose an elevator guard structure that enables independent action and coordinated operation of the upper and lower guard doors, optimizes space utilization efficiency, and thereby improves the safety and ease of operation of the elevator.

[0006] This application is achieved through the following technical solution:

[0007] This application proposes an elevator protection structure, including a car and a car door mechanism disposed on the car, wherein the car has a door opening, and the car door mechanism includes:

[0008] The first protective mechanism includes a first protective door and a first driving mechanism. The first protective door is slidably connected to the car at the doorway position. The first driving mechanism is located on the top surface of the car and is drively connected to the first protective door. The first driving mechanism can drive the first protective door to move in the vertical direction.

[0009] The second protective mechanism includes a second protective door and a second driving mechanism. The second protective door is rotatably connected to the car at the doorway position. The second driving mechanism is located on the bottom end face of the car and is drively connected to the second protective door. The second protective door is located below the first protective door. The second driving mechanism can drive the second protective door to rotate in the vertical direction.

[0010] When the first drive mechanism drives the first guard door to move downward, and at the same time the second drive mechanism drives the second guard door to rotate vertically into the doorway, the edge of the first guard door fits into the edge of the second guard door.

[0011] In one embodiment of this application, the interior of the car is provided with a support surface. When the second drive mechanism drives the second guard door to rotate in a direction away from the car door, the support surface connects with the second guard door, and the second guard door forms a ramp.

[0012] In one embodiment of this application, the first drive mechanism includes a motor disposed on the top surface of the car, and the first guard door includes a rack. The motor meshes with the rack through a gear to drive the first guard door to move in a vertical direction.

[0013] In one embodiment of this application, the car is provided with guide rails on both sides of the door, the guide rails are adapted to the two sides of the first guard door, and both sides of the first guard door are slidably connected to the guide rails.

[0014] In one embodiment of this application, the second drive mechanism includes a push cylinder and a connecting mechanism. The push cylinder is disposed on the bottom end face of the car. One end of the connecting mechanism is rotatably connected to the push rod of the push cylinder, and the other end is rotatably connected to the second guard door.

[0015] The push rod of the push cylinder is extendable to drive the connecting mechanism to move, thereby causing the second guard door to flip open or close in the vertical direction.

[0016] In one embodiment of this application, the connecting mechanism includes a first connecting rod and a second connecting rod. One end of the first connecting rod is rotatably connected to the push rod of the push cylinder, and the other end is rotatably connected to the second connecting rod. The end of the second connecting rod away from the first connecting rod is rotatably connected to the second guard door.

[0017] When the push rod of the push cylinder extends, the first connecting rod pushes the second connecting rod, causing the second guard door to flip vertically into the doorway;

[0018] When the push rod of the push cylinder retracts, the first connecting rod pulls the second connecting rod, causing the second guard door to flip vertically to the outside of the doorway.

[0019] In one embodiment of this application, the interior of the car includes a receiving groove, which is connected to the door and located below the supporting surface. The second guard door is disposed in the receiving groove, and the edge of the second guard door is rotatably connected to the side wall of the car in the receiving groove.

[0020] In one embodiment of this application, the car is provided with a clearance groove, and the clearance groove is connected to the receiving groove;

[0021] When the second guard door flips vertically into the doorway, the second connecting rod passes through the clearance groove and the receiving groove in sequence and is rotatably connected to the second guard door.

[0022] In one embodiment of this application, the second drive mechanism further includes a positioning seat, which is disposed on the bottom end surface of the car, and the push cylinder is slidably connected to the positioning seat.

[0023] In one embodiment of this application, the bottom of the first guard door is provided with a rubber layer. When the first driving mechanism drives the first guard door to move downward, and at the same time the second driving mechanism drives the second guard door to rotate vertically into the doorway, the rubber layer is in contact with the second guard door.

[0024] Compared with the prior art, the beneficial effects of this application are:

[0025] The first safety mechanism includes a first safety door and a first drive mechanism. The first safety door is slidably connected to the car at the doorway. The first drive mechanism is located on the top surface of the car and is driven by the first safety door. The first drive mechanism can drive the first safety door to move vertically, realizing the sliding action of the first safety door in the vertical direction. The second safety mechanism includes a second safety door and a second drive mechanism. The second safety door is rotatably connected to the car at the doorway. The second drive mechanism is located on the bottom surface of the car and is driven by the second safety door. The second safety door is located below the first safety door, and the second drive mechanism can drive the second safety door to rotate vertically. When the first safety door slides downward vertically under the drive of the first drive mechanism, and the second safety door flips upward into the doorway under the action of the second drive mechanism, the edges of the two doors fit together, completing the coordinated closing operation of the upper and lower safety doors, realizing rapid opening or closing. Through this design, the upper and lower safety doors operate independently yet in coordination, resulting in a more reliable sealing effect. This elevator car door mechanism has significant improvements over traditional solutions in terms of space utilization, ease of operation, safety, and flexibility. It can flexibly realize the independent action and coordinated operation of the first and second guard doors, optimize space utilization efficiency, and thus improve the safety and ease of operation of the elevator.

[0042] Please refer to Figures 1 to 6 This application proposes an elevator protection structure 10, including a car 100 and a car door mechanism 200 disposed on the car 100. The car 100 has a doorway 110. The car door mechanism 200 includes a first protection mechanism 210 and a second protection mechanism 220. The first protection mechanism 210 includes a first protection door 211 and a first drive mechanism (not shown in the figure). The first protection door 211 is slidably connected to the car 100 at the doorway 110. The first drive mechanism is disposed on the top surface of the car 100 and is drively connected to the first protection door 211. The first drive mechanism can drive the first protection door 211 to move in the vertical direction. The second protection mechanism 220... The system includes a second guard door 221 and a second drive mechanism (not shown in the figure). The second guard door 221 is rotatably connected to the car 100 at the doorway 110. The second drive mechanism is located on the bottom surface of the car 100 and is connected to the second guard door 221. The second guard door 221 is located below the first guard door 211. The second drive mechanism can drive the second guard door 221 to rotate in the vertical direction. When the first drive mechanism drives the first guard door 211 to move downward, and at the same time the second drive mechanism drives the second guard door 221 to rotate in the vertical direction into the doorway 110, the edge of the first guard door 211 fits against the edge of the second guard door 221.

[0043] Specifically, the first protective mechanism 210 and the second protective mechanism 220 are used to provide vertical and horizontal sealing protection for the elevator car 100 doorway 110. The first protective mechanism 210 includes a first protective door 211 and a first drive mechanism. The first protective door 211 is slidably installed at the doorway 110 of the car 100 and is driven by the first drive mechanism located on the top surface of the car 100 to achieve a vertical sliding motion. The second protective mechanism 220 includes a second protective door 221 and a second drive mechanism. The second protective door 221 is rotatably installed at the lower part of the doorway 110 of the car 100 and is driven by the second drive mechanism located on the bottom surface of the car 100 to achieve a flipping motion. When the first protective door 211 slides downwards vertically under the drive of the first drive mechanism, and simultaneously the second protective door 221 flips upwards into the doorway 110 under the action of the second drive mechanism, the edges of the two doors fit together, completing the coordinated closing operation of the upper and lower protective doors, achieving rapid opening or closing. With this design, the upper and lower guard doors operate independently yet in coordination, resulting in a more reliable sealing effect.

[0044] In summary, the sliding and flipping coordination of the first guard door 211 and the second guard door 221 effectively improves space utilization and avoids jamming or interference problems caused by unreasonable design in existing guard door structures, ensuring smooth operation. The sliding action of the first guard door mechanism 210, combined with the top drive design, avoids occupying the space on both sides of the doorway 110, while the second guard door mechanism 220, driven by the push cylinder 2212, achieves fast and precise opening and closing actions, making operation more convenient and safer. The edge-fitting design of the first guard door 211 and the second guard door 221 not only improves the sealing and stability of the enclosure but also reduces the risk of structural loosening or unreliable operation. This solution is particularly suitable for usage scenarios that require frequent adjustment of door states, such as when the elevator connects to a floor, allowing for quick switching of guard door states, improving the efficiency and safety of elevator operation. Overall, this elevator car door mechanism 200 has significant improvements over traditional solutions in terms of space utilization, operational convenience, safety, and flexibility, and can meet the increasingly demanding requirements of modern high-rise buildings for elevator operation.

[0045] Please refer to Figure 2 In one embodiment, a support surface 120 is provided inside the car 100. When the second drive mechanism drives the second guard door 221 to rotate in a direction away from the car door, the support surface 120 connects with the second guard door 221, and the second guard door 221 forms a ramp.

[0046] Specifically, the support surface 120 is used to support people or goods. The support surface 120 allows the second guard door 221 to connect with it when it flips open, realizing the conversion from a guard function to a temporary ramp function, greatly improving the elevator's flexibility and practicality. Specifically, when the second guard door 221 forms a ramp, it provides a smooth transition path for moving heavy objects or equipment, eliminating the inconvenience of traditional guard structures in areas with height differences. Furthermore, the flipping action of the second guard door 221 and the connection with the support surface 120 are precise and reliable, ensuring operational safety while avoiding the problem of additional structures occupying space in the car 100. This solves the problem of the single function of guard doors in existing technologies, and at the same time, the multi-functional door design expands the elevator's application scenarios, enabling it to meet complex needs such as goods handling and temporary connections between the elevator and floors, improving the convenience and safety of elevator operation, and demonstrating significant practical value and technological advantages.

[0047] Please refer to Figure 5 In one embodiment, the first drive mechanism includes a motor 212, which is located on the top surface of the car 100. The first guard door 211 includes a rack 2111, and the motor 212 meshes with the rack 2111 through a gear to drive the first guard door 211 to move in the vertical direction.

[0048] Specifically, the motor 212 meshes with the rack 2111 via gears, ensuring smooth vertical sliding of the first guard door 211 and enabling rapid opening and closing, thus improving operational efficiency. Positioning the motor 212 on the top surface of the car 100 fully utilizes the top space and avoids obstructing the space on both sides of the car door 110, supporting structural optimization and ease of passage. This solves the problems of complex transmission methods and large space occupation in existing technologies, providing efficient and reliable technical support for modern elevator guard door structures 10.

[0049] Please refer to Figure 1 , Figure 2 as well as Figure 5 In one embodiment, the car 100 is provided with guide rails 130 on both sides of the door 110. The guide rails 130 are adapted to the two sides of the first guard door 211, and both sides of the first guard door 211 are slidably connected to the guide rails 130.

[0050] Specifically, by installing guide rails 130 on both sides of the doorway 110 of the car 100 and slidingly connecting them to the sides of the first guard door 211, this technical solution further improves the operational stability and positioning accuracy of the guard door. The sliding support design of the guide rails 130 effectively prevents the first guard door 211 from shifting, jamming, or shaking due to uneven force or lateral interference during vertical sliding, ensuring the smooth movement of the guard door. In addition, the guide rail 130 structure restricts the sliding path of the guard door to a specific range, achieving precise control of the sliding action, while avoiding interference between the door body and the surrounding structure of the car 100, thereby improving the overall operational reliability and safety. This design simplifies the connection between the guard door and the car 100, facilitating installation and maintenance, while enhancing the impact resistance of the guard structure, providing an important guarantee for the long-term safe operation of the elevator.

[0051] Please refer to Figure 3 and Figure 4 In one embodiment, the second driving mechanism includes a push cylinder 2212 and a connecting mechanism. The push cylinder 2212 is located on the bottom end face of the car 100. One end of the connecting mechanism is rotatably connected to the push rod of the push cylinder 2212, and the other end is rotatably connected to the second guard door 221. The push rod of the push cylinder 2212 is extendable to drive the connecting mechanism (not shown in the figure) to move, thereby causing the second guard door 221 to flip open or close in the vertical direction.

[0052] The connecting mechanism includes a first link 2222 and a second link 2223. One end of the first link 2222 is rotatably connected to the push rod of the push cylinder 2212, and the other end is rotatably connected to the second link 2223. The end of the second link 2223 away from the first link 2222 is rotatably connected to the second guard door 221. When the push rod of the push cylinder 2212 extends, the first link 2222 pushes the second link 2223, causing the second guard door 221 to flip vertically into the doorway 110. When the push rod of the push cylinder 2212 retracts, the first link 2222 pulls the second link 2223, causing the second guard door 221 to flip vertically out of the doorway 110.

[0053] Specifically, the connecting mechanism formed by the first link 2222 and the second link 2223 enables flexible transmission between the push cylinder 2212 and the second retaining door 221. One end of the first link 2222 is rotatably connected to the push rod of the push cylinder 2212, and the other end is rotatably connected to the second link 2223. The other end of the second link 2223 is rotatably connected to the second retaining door 221. When the push rod of the push cylinder 2212 extends, the first link 2222 pushes the second link 2223, causing the second retaining door 221 to flip vertically into the doorway 110. When the push rod retracts, the first link 2222 pulls the second link 2223 in the opposite direction, causing the second retaining door 221 to flip out of the doorway 110.

[0054] Please refer to Figure 1 , Figure 2 and 6 In one embodiment, the interior of the car 100 includes a receiving groove 140, which is connected to the door 110. The receiving groove 140 is located below the support surface 120. A second guard door 221 is disposed in the receiving groove 140, and the edge of the second guard door 221 is rotatably connected to the side wall of the car 100 in the receiving groove 140.

[0055] Specifically, the second guard door 221 is located in the receiving groove 140, and the edge of the second guard door 221 is rotatably connected to the side wall of the car 100 in the receiving groove 140.

[0056] Please refer to Figure 1 , Figure 2 and 6 In one embodiment, the interior of the car 100 includes a receiving groove 140, which is connected to the door 110. The receiving groove 140 is located below the support surface 120. A second guard door 221 is disposed in the receiving groove 140, and the edge of the second guard door 221 is rotatably connected to the side wall of the car 100 in the receiving groove 140.

[0057] Please refer to Figure 1 , Figure 2 and 6 In one embodiment, the car 100 is provided with a clearance groove 150, which is connected to the receiving groove 140. When the second guard door 221 is flipped vertically into the doorway 110, the second connecting rod 2223 passes through the clearance groove 150 and the receiving groove 140 in sequence and is rotatably connected to the second guard door 221.

[0058] Specifically, by adding a clearance groove 150 and connecting it to the receiving groove 140, the linkage mechanism is not restricted by space during the process of driving the second guard door 221 to flip. The clearance groove 150 avoids interference between the linkage and other structures of the car 100 during the flipping process.

[0059] Please refer to Figure 1 In one embodiment, the second drive mechanism further includes a positioning seat 2224, which is located on the bottom end face of the car 100, and the push cylinder 2212 is slidably connected to the positioning seat 2224.

[0060] Specifically, by setting a positioning seat 2224 and slidingly connecting it with the push cylinder 2212, the support stability and transmission accuracy of the push cylinder 2212 during operation are improved. The positioning seat 2224 provides a fixed fulcrum for the push cylinder 2212 structurally, while allowing the push cylinder 2212 to be finely adjusted according to the motion requirements of the linkage mechanism during operation, thereby effectively avoiding thrust offset problems caused by mechanical errors or external forces.

[0061] Please refer to Figure 1 and Figure 2 In one embodiment, the bottom of the first barrier door 211 is provided with a rubber layer 2112. When the first drive mechanism drives the first barrier door 211 to move downward, and at the same time the second drive mechanism drives the second barrier door 221 to rotate in the vertical direction into the doorway 110, the rubber layer 2112 is in contact with the second barrier door 221.

[0062] Specifically, by setting a rubber layer 2112 at the bottom of the first guard door 211, the problems of gaps, collisions, or poor sealing that may occur when the upper and lower guard doors are attached are solved, significantly improving the sealing performance, stability, and safety of the guard door. The flexible properties of the rubber layer 2112 provide a buffering effect for the guard door, avoiding damage to the door body that may be caused by rigid attachment.

[0063] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
