[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to the accompanying drawings.

[0020] Reference Figure 1 and Figure 2A self-balancing elevator includes an elevator car, an elevator shaft, an elevator control system, a dynamic balancing system, and a visual system. The elevator car is located within the elevator shaft, which is also equipped with a traction system that pulls the elevator car up and down. The traction system pulls the elevator car up and down within the elevator shaft. An internal call panel is installed within the elevator car, and an external call panel is installed in the elevator hall. These panels, as well as the traction system, are all connected to the elevator control system, which controls the movement of the elevator car and the floors it stops at based on touch inputs to the internal and external call panels.

[0021] About dynamic balancing system

[0022] The dynamic balancing system 2 includes a first guide rail fixed to the bottom of the elevator car 1. The first guide rail is annular and has a counterweight 24 mounted on it. The dynamic balancing system 2 also includes a first drive motor that drives the counterweight 24 to rotate along the first guide rail. The first drive motor is connected to the elevator control system. When the elevator control system detects an uneven distribution of passengers or cargo, resulting in an unbalanced load, the elevator control system controls the first drive motor to rotate, moving the counterweight 24 toward the side with fewer passengers or cargo. The present invention uses an annular track. Compared to a cross track or a square track, the counterweight 24 can reach a wider range of positions, thereby making the elevator more balanced.

[0023] Preferably, the first guide rail consists of two semicircular sub-rails 23. Upwardly extending support frames 21 are provided at each end of the sub-rails 23, with the top of the support frames 21 fixedly connected to the bottom of the elevator car 1. A first tooth is provided on the upper end surface of the sub-rail 23. A notch is provided above the counterweight 24, and a rotating shaft 22 is provided in the notch. The rotating shaft 22 is provided with a second tooth that mates with the first tooth. The motor shaft of the first drive motor can be connected to the rotating shaft, or the motor shaft of the first drive motor can directly serve as the rotating shaft. The rotating shafts of the two counterweights 24 respectively pass through the gaps between the two sub-rails 23 and the bottom of the elevator car 1. The present invention, through the semicircular sub-rails 23 and the two counterweights 24, shortens the movable distance of the counterweight 24, thereby accelerating the time it takes for the counterweight 24 to reach a designated position. Furthermore, when the elevator car 1 is balanced, the two counterweights 24 are symmetrically arranged, effectively resolving the imbalance caused by the counterweight 24 when no passengers are on board, when a single counterweight 24 is used. In the case of two counterweights 24, the elevator control system controls both counterweights 24 to move to a position with fewer passengers and less cargo until they move to a designated position or touch the support frame 21. The support frame 21 is preferably coated with a rubber layer to provide shock absorption and prevent the shaft from colliding with the support frame 21.

[0024] The first drive motor is preferably fixed on the counterweight 24, thereby increasing the weight of the counterweight 24. It is further preferred that the counterweight 24 is provided with a hollow in the horizontal direction, and the first drive motor is fixed in the hollow. Preferably, the motor shaft 25 of the first drive motor extends to the central axis of the elevator car 1. A first gear is provided on the motor shaft 25 of the first drive motor, and an extension is provided on the side of the rotating shaft close to the center of the elevator car 1. The extension is provided with a second gear 26 that matches the first gear, and the first gear and the second gear 26 are connected by a transmission chain. The present invention optimizes the position and orientation of the first drive motor, making the fixation of the present invention more convenient, and more importantly, the operation is stable and the external interference is small.

[0025] The two sub-guide rails are symmetrically arranged with the door gap of the elevator car as the symmetry plane, so that the elevator can maintain balance during the process of opening and closing the door.

[0026] About Vision Systems

[0027] The AI ​​camera vision system 3 includes a second rectangular rail 31. Both ends of the AI ​​camera second rail 31 are fixedly connected to the elevator car ceiling via connecting plates 311. The AI ​​camera second rail 31 is parallel to the car door of the AI ​​camera 33. A suspension mount 32 is suspended from the AI ​​camera second rail 31, with the AI ​​camera 33 fixed to its lower end. The AI ​​camera vision system 3 also includes a second drive motor 34, which drives the AI ​​camera suspension mount 32, causing the AI ​​camera suspension mount 32 to move along the AI ​​camera second rail 31. The elevator control system can determine the distribution of passengers or cargo within the car based on the images captured by the AI ​​camera 33. This can be done manually by simply capturing the images, or by using a built-in program after capturing the images. The AI ​​camera 33 is a network-based intelligent AI camera 33 with a built-in artificial intelligence algorithm chip that performs language and image recognition on the video data captured by the front-end camera. The AI ​​camera 33 of the present invention utilizes the latest AI camera technology, which improves judgment accuracy and reduces the computing power requirements of the elevator control system.

[0028] The AI ​​camera's second guide rail 31 preferably passes through the center of the elevator car's ceiling, where the AI ​​camera 33 is located. This ensures that both sides of the second guide rail 31 are balanced. Furthermore, the second guide rail 31 and the bidirectional screw 35 are preferably arranged symmetrically with the elevator car door's door gap as the plane of symmetry. This ensures the elevator maintains balance even during door opening and closing. The length of the AI ​​camera's second guide rail 31 is preferably greater than the width of the elevator car's door. This allows the AI ​​camera 33 to reach further locations, effectively preventing obstruction of the AI ​​camera 33.

[0029] The elevator car's roof preferably includes a roof panel and a decorative panel 36 positioned below the roof panel. The AI ​​camera decorative panel 36 has a cutout at the path of the suspension mount 32. The AI ​​camera's second guide rail 31 is positioned above the AI ​​camera decorative panel 36. The width of the AI ​​camera's second guide rail 31 is greater than the width of the cutout for the AI ​​camera 33. The width of the AI ​​camera's suspension mount 32 is less than the width of the cutout for the AI ​​camera 33. The AI ​​camera 33 is positioned below the AI ​​camera decorative panel 36. This arrangement shields the cutout with the second guide rail 31. The AI ​​camera's second drive motor 34 is secured to the exterior roof of the elevator car. The motor shaft of the AI ​​camera's second drive motor 34 passes through the roof panel and extends between the AI ​​camera 33's roof panel and the AI ​​camera decorative panel 36. This reduces the required distance between the roof panel and the decorative panel 36. Furthermore, compared to mounting the motor on the decorative panel 36, the load-bearing capacity requirement for the decorative panel 36 can be reduced. On the other hand, compared with the structure in which the second drive motor 34 is located inside the elevator car, the second drive motor 34 located outside the elevator car has a better heat dissipation effect and is more convenient to maintain.

[0030] A through groove running through the upper and lower parts is provided in the middle of the second guide rail 31 of the AI ​​camera. The cross section of the AI ​​camera hanging seat 32 is rectangular. The AI ​​camera hanging seat 32 extends into the through groove of the AI ​​camera 33. A bracket shaft is provided at each end of the top of the AI ​​camera hanging seat 32, and a roller is provided on both sides of each bracket shaft.

[0031] The vision system also includes a bidirectional screw 35, with an AI camera suspension mount 32 threadedly connected to each side of the AI ​​camera bidirectional screw 35. A first gear 341 is mounted on the motor shaft of the AI ​​camera's second drive motor 34, and a second gear 351 is mounted in the middle of the AI ​​camera bidirectional screw 35. The first gear 341 of the AI ​​camera 33 engages the second gear 351 of the AI ​​camera 33. Preferably, each side of the AI ​​camera suspension mount 32 is provided with a second extension extending horizontally outward, and the AI ​​camera bidirectional screw 35 passes through the two second extensions located on the same side of the two suspension mounts 32. The AI ​​camera decorative plate 36 has an upwardly extending flange at the hollow portion, using the flange of the AI ​​camera 33 as a guide plate. A roller is mounted on the AI ​​camera's second extension, pressing against the AI ​​camera decorative plate 36. The roller is located on the side of the guide plate away from the hollow portion. The roller and guide plate thus form a guide structure, ensuring more stable camera movement.

[0032] Yes, there are two bidirectional screws 35, which pass through the second extensions on both sides of the suspension base 32 respectively. There is only one second drive motor 34 for the AI ​​camera, and the second drive motor 34 for the AI ​​camera drives the two bidirectional screws 35 synchronously, thereby making the movement of the camera more stable.

[0033] The self-balancing adjustment method of the self-balancing elevator is preferably that the elevator control system judges the distribution of passengers or cargo in the elevator car through the images inside the elevator car captured by the AI ​​camera 33. Preferably, the second drive motor 34 controls the AI ​​camera 33 to move on the second guide rail 31, so as to capture images from more than one angle to improve the accuracy of the judgment. For example, if a passenger has a cat in their arms, a single camera or a fixed camera may only capture the passenger. The present invention can detect the cat in the passenger's arms with a greater probability through the movement of the camera, thereby making the judgment of the distribution of each passenger or cargo more accurate. In addition, some AI cameras 33 have the function of predicting behavior and actions. Such cameras can be used to predict the passenger's next move in advance and adjust the dynamic balancing system in advance. For example, if a passenger is predicted to get off the elevator, the dynamic balancing system can start the first drive motor in advance, causing the counterweight to move slowly away from the door, and then move quickly when the passenger gets off the elevator. Preferably, the elevator control system controls the AI ​​camera 33 to move back and forth and capture images inside the elevator car at intervals. The interval here can be a time interval or a distance interval. The distance interval means taking pictures at different positions of the second guide rail 31.
