Description

Technical Field

[0001] The invention belongs to the technical field of elevators, and in particular relates to a high-speed elevator car. Background Art

[0002] Elevators are an indispensable and important part of modern buildings. As the height of buildings continues to increase, the operating speed of elevators is also increasing. For high-speed elevator cars, their safety and operating comfort are particularly important.

[0003] In terms of safety, the elevator needs to monitor the guide rails for deviation at all times during operation to ensure the safety of passengers. When the guide rails are seriously deviated, the elevator needs to be automatically stopped. At this time, for the safety of passengers, it should be ensured that maintenance personnel can inspect the elevator as soon as possible.

[0004] In terms of running comfort, during the normal operation of the elevator, the uneven standing positions of the passengers in the car and the changes in the length of the wire rope and the compensation rope cause a slight shift in the center of gravity of the car, that is, overloading. At this time, the overloading of the car causes the roller on one side of the guide shoe to be stressed and compress the spring, causing the car to tilt, resulting in poor riding comfort for the passengers. Summary of the invention

[0005] The present invention aims at the above problems existing in the prior art and proposes a high-speed elevator car which can monitor whether the guide rail is offset at all times during high-speed operation, facilitate maintenance by operators, and automatically adjust the center of gravity of the car.

[0006] The present invention can be achieved through the following technical solutions:

[0012] A dynamic balancing component is arranged in the balancing cavity. The dynamic balancing component cooperates with the guide rail offset self-monitoring device through a control system. When the reading of the guide rail offset self-monitoring device changes, the control system controls the movement of the dynamic balancing component and keeps the car body in a horizontal state at all times.

[0017] As a further improvement of the present invention, the connecting line of the first side ranging sensor and the second side ranging sensor and the extension line of the end face ranging sensor are arranged in a T shape, wherein the end face ranging sensor is arranged toward the end face of the shaft guide rail, and the first side ranging sensor and the second side ranging sensor are respectively arranged toward the two side faces of the shaft guide rail.

[0018] As a further improvement of the present invention, the dynamic balancing assembly comprises:

[0019] A bracket, whose internal arrangement structure forms the balancing cavity, the bracket is provided with a first groove rail and a second groove rail, the first groove rail and the second groove rail are arranged in parallel and are movably connected to the bracket;

[0020] There are multiple groups of balancing blocks, and each group of balancing blocks is movably disposed on the first groove rail and the second groove rail through a slider;

[0021] A transverse drive motor and a transverse screw rod, wherein the transverse drive motor is connected to the transverse screw rod through a driven nut, and a balance block on the first groove rail and a balance block on the second groove rail are respectively connected to the transverse screw rod;

[0022] A longitudinal drive motor and a longitudinal screw rod, wherein the longitudinal screw rod is connected to the longitudinal drive motor through a driven nut, and both ends of the longitudinal screw rod are connected to the transverse screw rod through a connecting piece.

[0023] As a further improvement of the present invention, the balancing block, the transverse screw rod and the longitudinal screw rod are connected together to form an integral balancing group.

[0024] As a further improvement of the present invention, when the reading of the end face distance measuring sensor changes, the control system controls the lateral drive motor to drive the weight group to move lateraly.

[0025] As a further improvement of the present invention, when the readings of the first side distance measuring sensor and the second side distance measuring sensor change, the control system controls the longitudinal drive motor to drive the weight group to move longitudinally.

[0026] As a further improvement of the present invention, the inner side of the hatch door of the inspection cabin is provided with:

[0027] The door lock assembly is arranged in a Z-shaped structure and comprises two parallel connecting rod latches and a rotary lock, wherein the two connecting rod latches are arranged vertically and are respectively connected to two ends of the rotary lock;

[0028] The door lock closing verification switch is located on the side of the rotary lock and is connected to the safety circuit. When the rotary lock rotates to contact the door lock closing verification switch, the door lock closing verification switch transmits a signal to the safety circuit, and the control system automatically controls the car body to stop.

[0029] As a further improvement of the present invention, sleeves are provided on the upper and lower sides of the door of the maintenance cabin, and the connecting rod latch is cooperatively connected with the sleeves.

[0030] As a further improvement of the present invention, the door of the maintenance cabin is also provided with a plurality of operation buttons, and the operation buttons are located on the outside of the door.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The guide rail offset self-monitoring device has three sensors, which respectively measure the distance between the end face of the convex part of the hoistway guide rail and the two side faces, so as to accurately monitor whether the hoistway guide rail has offset, deformation, misalignment and other problems. In addition, during the operation of the elevator, the offset and deformation can be continuously and real-time monitored. When they exceed a certain range, the control system can perform an emergency stop on the elevator.

[0033] 2. The dynamic balancing component cooperates with the guide rail offset self-monitoring device through the control system. When the reading of the guide rail offset self-monitoring device changes, the control system can control the dynamic balancing component to make corresponding fine adjustments according to the reading changes, and continuously adjust the center of gravity position of the car body and the wire rope suspension position in the vertical direction to coincide, thereby achieving dynamic balance of the car body during high-speed operation and improving the riding comfort of passengers.

[0034] 3. The door of the maintenance cabin is always in the closed state during the normal operation of the elevator. Once the rotary lock is opened, the elevator will stop suddenly. That is to say, the door of the maintenance cabin is not allowed to be opened during the normal operation of the elevator. After the operator enters the maintenance cabin, the rotary lock will automatically reset under the action of the compression spring, and the door lock closure verification switch transmits a signal to the safety circuit. The control system releases the immediate stop state of the car body. At this time, no matter whether the door of the maintenance cabin is in the open or closed state, the elevator can run, which is convenient for the operator to carry out maintenance, and the operator performs maintenance work in the maintenance cabin, which is safer.

[0035] 4. Through the setting of the door lock assembly with self-locking function and the door lock closing verification switch, the elevator can continue to run during the maintenance process. Once a major fault occurs, such as the guide rail offset self-monitoring device detects that the offset or deformation of the shaft guide rail exceeds the preset range, the elevator automatically stops. At this time, the operator enters the maintenance cabin for maintenance. When the problem is solved, the elevator can start running. At the same time, the operator can continue to conduct further inspections and maintenance in the maintenance cabin, which greatly improves the maintenance efficiency and allows the elevator to resume operation as soon as possible.

[0036] 5. The air pressure sensor in the car body can monitor the pressure value in the car body at all times and feed it back to the air pressure controller. The air pressure controller controls the start of the blower or exhaust fan accordingly by comparing the pressure difference inside and outside the car body to ensure that the air pressure changes in the car body are relatively stable, thereby improving the comfort of passengers when riding in high-speed elevators.

DETAILED DESCRIPTION

[0047] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0048] like Figure 1-9 As shown, the present invention provides a high-speed elevator car, comprising:

[0049] The car body 100.

[0050] The maintenance cabin 200 is arranged on the top of the car body 100. When the elevator fails, maintenance personnel enter the maintenance cabin 200 to perform maintenance.

[0051] The guide rail offset self-monitoring device 300 is arranged on the outer wall of the inspection cabin 200 and is arranged toward the external hoistway guide rail 310. The guide rail offset self-monitoring device 300 can simultaneously detect the distance between each surface of the hoistway guide rail 310;

[0052] Specifically, during the maintenance phase before the normal operation of the elevator, by observing the change in the distance between the guide rail offset self-monitoring device 300 and each surface of the hoistway guide rail 310, the installation accuracy of the hoistway guide rail 310 can be accurately and comprehensively corrected to ensure the safety of the subsequent elevator operation;

[0053] During the normal operation of the elevator, since the guide rail offset monitoring device 300 is electrically connected to the elevator control system, the horizontal offset, deformation, misalignment, etc. of the shaft guide rail 310 during operation can be effectively monitored, and the maximum offset and deformation of the shaft guide rail 310 are preset in the elevator control system. Once the offset and deformation of the shaft guide rail 310 exceeds the preset value during the operation of the elevator, the control system will perform an emergency stop on the elevator to avoid danger and further improve the safety of the elevator during high-speed operation.

[0054] The balancing cavity 400 is disposed at the bottom of the car body 100 .

[0055] The dynamic balancing component 410 is arranged in the balancing cavity 400. The dynamic balancing component 410 cooperates with the guide rail offset self-monitoring device 300 through the control system. When the reading of the guide rail offset self-monitoring device 300 changes, the control system controls the dynamic balancing component 410 to move and makes the car body 100 always in a horizontal state. That is to say, the guide rail offset self-monitoring device 300 is not only used to monitor the position accuracy of the guide rail, but also can serve the dynamic balance of the car body 100. This is because the wire rope and the compensation rope change with the position of the car body 100 in the hoistway, which will cause a slight and continuous eccentric load on the car body 100, and at the same time, the distance reading of the guide rail offset self-monitoring device 300 will also change continuously. At this time, the control system can control the dynamic balancing component 410 to perform corresponding fine-tuning according to the change of the reading of the guide rail offset self-monitoring device 300, and continuously adjust the center of gravity position of the car body 100 to coincide with the wire rope suspension position in the vertical direction, thereby achieving the dynamic balance of the car body 100 during high-speed operation and improving the riding comfort of passengers;

[0056] That is to say, in this embodiment, the guide rail offset self-monitoring device 300 is linked with the dynamic balancing system to ensure not only the position accuracy of the hoistway guide rail 310 is always kept within a safe range, but also the dynamic balance can be maintained during high-speed operation of the elevator.

[0057] It is worth mentioning here that the existing guide rail offset detection equipment is generally used in the acceptance inspection stage after the elevator is installed. It is a movable detection equipment used by elevator inspectors to measure the installation quality (such as horizontal deviation, vertical deviation, etc.) of the car body 100 or the shaft guide rails 310 on both sides of the counterweight. It requires manual operation and is affected by installation accuracy. At the same time, it is not a device that comes with the elevator itself, and the measured data has nothing to do with the elevator's own control system, etc., and is not used for the elevator itself.

[0058] In comparison, the guide rail deviation self-monitoring device 300 provided in this embodiment is a device and function that comes with the elevator. Its analog data needs to enter the control system and is one of the tools used to monitor the normal operation of the elevator and inspect the safety status (guide rail deviation) during operation. Its deviation detection of the shaft guide rail 310 after installation and providing data support for the correction of the shaft guide rail 310 are only one of its functions. Its most important function is to monitor the relative position between the car body 100 and the shaft guide rail 310 during operation (including the changes in the hanging weight of the car body 100 and the position of the passengers in the car body 100, such as the horizontal deformation of the shaft guide rail 310 caused by the deformation of the building caused by earthquakes, strong winds, etc., and the irregular deviation of the car caused by the wind pressure during high-speed operation of the car body 100), and feed back the detection data to the control system. The control system can control the dynamic balancing component to compensate for the deviation of the car body 100 within the range that the deviation can be compensated, thereby ensuring the stability of the car body 100 during the operation of the elevator. If compensation cannot be made, the elevator is controlled to stop running to ensure the safety of the elevator during operation.

[0059] Preferably, the guide rail deviation self-monitoring device 300 comprises:

[0060] The installation straight beam 320 is connected to the outer wall of the inspection cabin 200. The installation straight beam 320 is arranged in a U-shaped structure. The shaft guide rail 310 extends into the U-shaped area of ​​the installation straight beam 320. Specifically, the cross section of the shaft guide rail 310 is a T-shaped structure, and the convex part of the T-shaped structure extends into the U-shaped area of ​​the installation straight beam 320.

[0061] The end face distance measuring sensor 330 is arranged at the concave edge of the mounting straight beam 320 and is arranged toward the hoistway guide rail 310;

[0062] The first side distance measuring sensor 340 and the second side distance measuring sensor 350 are respectively disposed on two sides of the mounting straight beam 320 and are both disposed toward the hoistway guide rail 310 .

[0063] Further preferably, the connecting line of the first side ranging sensor 340 and the second side ranging sensor 350 and the extension line of the end face ranging sensor 330 are arranged in a T shape, wherein the end face ranging sensor 330 is arranged toward the end face of the shaft guide rail 310, and the first side ranging sensor 340 and the second side ranging sensor 350 are respectively arranged toward the two side faces of the shaft guide rail 310. That is to say, in this embodiment, the guide rail offset self-monitoring device 300 has three sensors, which respectively correspond to measuring the distance between the end face of the convex part of the shaft guide rail 310 and the two side faces, so that it can accurately monitor whether the shaft guide rail 310 has problems such as offset, deformation, and misalignment, and during the operation of the elevator, it can also continuously and real-time monitor the offset and deformation, and then when they exceed a certain range, the control system can perform an emergency stop on the elevator.

[0064] It is precisely because the guide rail offset self-monitoring device 300 in this embodiment includes three sensors and each sensor is respectively arranged toward each end face of the shaft guide rail 310, so that no matter whether the shaft guide rail 310 has horizontal offset or irregular offset, there is always at least one sensor that monitors the offset data. When the offset data is transmitted to the control system, the control system can control the dynamic balancing component 410 to make adaptive adjustments accordingly, so as to continuously adjust the center of gravity position of the car body 100 to coincide with the wire rope suspension position in the vertical direction, thereby achieving dynamic balance of the car body 100 in various complex situations with high adjustment accuracy.

[0065] Preferably, the dynamic balancing assembly 410 includes:

[0066] The bracket 420 has an internal structure forming a balancing cavity 400. The bracket 420 is provided with a first groove rail 421 and a second groove rail 422. The first groove rail 421 and the second groove rail 422 are arranged in parallel and are respectively located on two sides of the bracket 420.

[0067] The balancing blocks 430 are provided in multiple groups, and each group of balancing blocks 430 is movably provided on the first groove rail 421 and the second groove rail 422 through a slider 431. In the present embodiment, the number of the balancing blocks 430 is preferably set to four, wherein two balancing blocks 430 are respectively installed at both ends of the first groove rail 421, and the other two balancing blocks 430 are respectively installed at both ends of the second groove rail 422;

[0068] A longitudinal drive motor 440 and a longitudinal screw rod 450, wherein the longitudinal drive motor 440 is connected to the longitudinal screw rod 450 through a driven nut 441, and the two ends of the longitudinal screw rod 450 are respectively connected to the first groove rail 421 and the second groove rail 422, thereby the first groove rail 421, the second groove rail 422 and the longitudinal screw rod 450 form an I-shaped structure, and when the longitudinal drive motor 440 is running, the driven nut 441 can drive the longitudinal screw rod 450 to move longitudinally, thereby driving the first groove rail 421 and the second groove rail 422 to move longitudinally along the bracket 420, and then each balancing block 430 moves longitudinally;

[0069] A transverse drive motor 460 and a transverse screw rod 470, wherein the transverse drive motor 460 is connected to the transverse screw rod 470 through a driven nut 441, and the balancing block 430 on the first groove rail 421 and the balancing block 430 on the second groove rail 422 are respectively connected to the transverse screw rod 470, and the end of the transverse screw rod 470 and the longitudinal screw rod 450 are connected through a connecting piece 480, at which time each balancing block 430, the transverse screw rod 470 and the longitudinal screw rod 450 form an I-shaped structure, and when the transverse drive motor 460 is running, the transverse screw rod 470 can be driven to move transversely through the driven nut 441, and in this process, the entire I-shaped structure is driven to move transversely;

[0070] Therefore, the entire dynamic balancing assembly 410 can be moved in the horizontal or vertical direction to adjust the center of gravity of the car body 100, so as to achieve the purpose of always maintaining dynamic balance of the car body 100 during operation;

[0071] Specifically, when the elevator is not put into normal use, the static balance adjustment is completed first. In the static balance state, the quantity and quality of the balance blocks 430 in the front, back, left and right directions will be inconsistent, but the car body 100 is in a horizontal state. At this time, the guide shoe roller is not subjected to force. In this state, the position of the guide rail offset monitoring sensor is adjusted to keep the distance between the first side distance sensor 340, the second side distance sensor 350 and the two sides of the shaft guide rail 310 consistent. At the same time, the end face sensors on the installation straight beams 320 on the left and right sides of the inspection cabin 200 are consistent with the end face distance of the shaft guide rail 310. The distance readings of each sensor at this time are set to the initial value;

[0072] During the normal operation of the elevator, when the car body 100 is overloaded due to uneven passenger standing positions and changes in the length of the wire rope and the compensation rope, the roller on one side of the guide shoe will be stressed and the spring will be compressed, causing the car frame to tilt. At this time, the readings of each sensor will change accordingly. Among them, when the readings of the first side distance sensor 340 and the second side distance sensor 350 change, the car body 100 is longitudinally overloaded. After feedback to the control system, the control system gives a corresponding signal to the longitudinal drive motor 440 to drive the four balance blocks 430 to move longitudinally, adjust the longitudinal change of the center of gravity of the car body 100 until it reaches the initial state, and the car body 100 can be restored to a horizontal state;

[0073] When the reading of the end distance sensor 330 changes, the car body 100 is laterally overloaded. After feedback to the control system, the control system gives a corresponding signal to the transverse drive motor 460 to drive the four balance blocks 430 to move laterally and adjust the longitudinal change of the center of gravity of the car body 100 until it reaches the initial state;

[0074] When the readings of the end face distance measuring sensor 330, the first side distance measuring sensor 340 and the second side distance measuring sensor 350 change at the same time, the car is obliquely overloaded. After feedback to the control system, the control system simultaneously gives corresponding signals to the transverse drive motor 460 and the longitudinal drive motor 440, driving the balance block 430 to move laterally and longitudinally at the same time, adjusting the longitudinal change of the center of gravity of the car body 100 until it reaches the initial state, thereby achieving a dynamic balance state of the entire car body 100 when running in the shaft.

[0075] It is worth mentioning here that the currently commonly used dynamic balancing device relies on a pressure sensor arranged between the car body 100 and the car bottom bracket to monitor the gravity changes at various positions inside the car body 100 to control the movement of the balance block 430 arranged at the center of the car bottom. However, this dynamic balancing system cannot monitor and compensate for the gravity changes from the outside (for example, the tension changes of the compensation chain and the relative displacement changes between the car body 100 and the shaft guide rail 310 caused by the offset of the shaft guide rail 310 cannot be monitored and compensated). At the same time, the large-area balance block 430 in the structure is placed near the center of the car body 100. The national standard requires that elevators with a speed ≥3.5m / s need to use a compensation rope system (such as a high-speed elevator). Because the weight of the compensation rope system is very high, when the shaft height exceeds a certain value, it can even exceed the weight of the car body 100 itself, resulting in its weight being unable to be balanced by the balance block 430. Therefore, this structure is not suitable for high-speed elevators or even ultra-high-speed elevators.

[0076] In comparison, the present embodiment achieves static balance of the car in advance by means of the hanging position and hanging weight of the balance block 430 at the four corners of the car body 100's car floor, and sets the center of gravity position to 0 after being fixed. Subsequently, during the operation of the elevator, all factors that affect the change in the center of gravity position of the car body 100 (including the external hanging weight of the car body 100 and the change in the position of the passengers in the car body 100, the horizontal deformation of the shaft guide rail 310 caused by any reason, the irregular offset of the car body 100 caused by wind pressure during high-speed operation, etc.) can be monitored through the relative position change between the car body 100 and the shaft guide rail 310, and the automatic balancing system will give compensation and correction accordingly. It is suitable for high-speed elevators and even ultra-high-speed elevators.

[0077] In addition, the compensation rope system needs to act on the center of gravity of the car body 100 to minimize the impact on the balance state during operation. In this regard, the arrangement of the balance block 430 in the present device can reserve the center of gravity of the car body 100 for hanging compensation ropes, cables, etc., and is no longer restricted by the height of the elevator shaft, the elevator running speed, etc., and can be used for high-speed elevators and ultra-high-speed elevators.

[0078] In addition, in this embodiment, in order to improve the stability of the balancing block 430 when moving, the balancing block 430 is connected to the first groove rail 421 and the second groove rail 422 through the structural cooperation of the slider 431 and the slide rail 432, and a guide assembly is also provided on both sides, and the guide assembly includes:

[0079] A mounting block 433 connected to the balancing block 430;

[0080] The guide wheel 434 and the spring 435, the guide wheel 434 is connected to the mounting block 433 through the spring 435, when the balancing block 430 moves along the first groove rail 421 and the second groove rail 422, the guide wheel 434 plays a guiding role, and the setting of the spring 435 plays a longitudinal limiting role, ensuring that the guide wheel 434 is always located on the moving track, thereby ensuring the stability of the balancing block 430 when moving.

[0081] Preferably, the door of the inspection cabin 200 is provided with:

[0082] The door lock assembly 220 is arranged in a Z-shaped structure and includes two parallel connecting rod pins 221 and a rotary lock 222. The two connecting rod pins 221 are arranged vertically and connected to the two ends of the rotary lock 222 respectively, and the connecting rod pins 221 cooperate with the plug sleeves 224 arranged on the upper and lower sides of the door of the inspection cabin 200. When the operator opens the rotary lock 222 with a key, the rotation of the rotary lock 222 will drive the two connecting rod pins 221 to move in the vertical direction and disengage from the plug sleeves 224. At this time, the door can be opened inward, and the entire door opening process is simple and quick;

[0083] The door lock closure verification switch 223 is located at the side of the rotary lock 222 and is connected to the safety circuit. When the rotary lock 222 is not opened, the rotary lock 222 is separated from the door lock closure verification switch 223. When the rotary lock 222 is opened, the rotary lock 222 rotates to contact the door lock closure verification switch 223. At this time, the door lock closure verification switch 223 transmits a signal to the safety circuit, and the control system automatically controls the car body 100 to stop, thereby ensuring the safety of the operator when entering the inspection cabin 200;

[0084] Therefore, in this embodiment, the door of the inspection cabin 200 is always in a closed state during the normal operation of the elevator, and once the rotary lock 222 is opened, the elevator will stop suddenly. That is to say, the door of the inspection cabin 200 is not allowed to be opened during the normal operation of the elevator. After the operator enters the inspection cabin 200, the rotary lock 222 will automatically reset under the action of the compression spring, and the door lock closing verification switch 223 transmits a signal to the safety circuit, and the control system releases the immediate stop state of the car body 100. At this time, no matter whether the door of the inspection cabin 200 is in an open state or a closed state, the elevator can run, which is convenient for the operator to carry out maintenance, and the operator performs maintenance work in the inspection cabin 200, which is safer.

[0085] Preferably, the door of the maintenance cabin 200 is also provided with a plurality of operating buttons 230, and the operating buttons 230 are located on the outside of the door. Specifically, when maintenance is required, if the elevator is not stopped at a suitable entry position, the maintenance personnel can stand at the hall door position and operate the elevator up and down to the required position through the operating buttons 230, so as to facilitate the maintenance personnel to enter the maintenance cabin 200.

[0086] It is worth mentioning here that in this embodiment, by providing a door lock assembly 220 with a self-locking function and a door lock closure verification switch 223, the elevator can continue to operate during the maintenance process. Once a major fault occurs, for example, when the guide rail offset self-monitoring device 300 detects that the offset or deformation of the shaft guide rail 310 exceeds a preset range, the elevator automatically stops in an emergency. At this time, the operator enters the maintenance cabin 200 for maintenance. When the problem is solved, the elevator can start running, and at the same time, the operator can continue to conduct further inspections and maintenance in the maintenance cabin 200, which greatly improves the maintenance efficiency and allows the elevator to resume operation as soon as possible.

[0087] In addition, the top wall and the side wall of the inspection cabin 200 are transitioned through an inclined surface or a curved surface, so that the inspection cabin 200 has the function of air diversion, reducing the resistance when the elevator is running at high speed, and the upper guide shoes 240 on both sides of the inspection cabin 200 are raised by the raising frame 250, thereby raising the connection point position between the car body 100 and the shaft guide rail 310, thereby reducing the amplitude of the center of gravity change during operation, thereby improving the stability of the entire car body 100 when running at high speed.

[0088] Preferably, since a high-speed elevator car is provided in this embodiment, the running speed is relatively fast. Therefore, in order to ensure the stability of the air pressure in the car body 100 to ensure the comfort of passengers, an air pressure regulating system is also provided in the car body 100. Specifically, the air pressure regulating system includes:

[0089] An air inlet 110 is provided at the bottom of the car body 100, and the air inlet 110 is externally connected to a blower (not shown);

[0090] An air outlet 120 is provided at the top of the car body 100, and the air outlet 120 is externally connected to an exhaust fan (not shown);

[0091] An air pressure sensor 130 is provided inside and outside the car body 100;

[0092] An air pressure controller 140 connected to the blower and the exhaust fan;

[0093] Specifically, the air pressure sensor 130 in the car body 100 can monitor the pressure value in the car body 100 at all times and feed it back to the air pressure controller 140. The air pressure controller 140 compares the pressure difference between the inside and outside of the car body 100, and controls the start-up of the blower or exhaust fan accordingly to ensure that the air pressure changes in the car body 100 are relatively stable, thereby improving the comfort of passengers when riding in high-speed elevators.

[0094] Furthermore, the air inlet 110 is divided into a plurality of air inlet areas, so as to change the flow direction of the air inlet and reduce the noise generated by the air inlet.

[0095] In addition, the gaps in the car body 100 are sealed by sealing strips to improve its sealing performance so as to be suitable for high-speed operation of the elevator.
