[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 in a circular ring shape, and a counterweight 24 is hung on the first guide rail; 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 finds that the passengers or goods are unevenly distributed and the load is unbalanced, the elevator control system controls the first drive motor to rotate so that the counterweight 24 moves to the side with fewer passengers or less goods. The present invention uses a circular ring track, and compared with a cross track or a square track, the counterweight 24 can reach a wider position, thereby making the elevator more balanced.

[0023] Preferably, the first guide rail is composed of two semicircular sub-rails 23, and the two ends of the sub-rails 23 are provided with support frames 21 extending upward, and the top of the support frame 21 is 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 at the notch, and a second tooth matching the first tooth is provided on the rotating shaft 22. It is possible that the motor shaft of the first drive motor is connected to the rotating shaft by transmission, or the motor shaft of the first drive motor is directly used as the rotating shaft. The two rotating shafts of the two counterweights 24 pass through the gap between the two sub-rails 23 and the bottom of the elevator car 1 respectively. The present invention shortens the movable distance of the counterweight 24 through the semicircular sub-rail 23 and the two counterweights 24, thereby accelerating the time for the counterweight 24 to move to the specified position. And when the elevator car 1 is balanced, the two counterweights 24 are symmetrically arranged, which can effectively solve the imbalance caused by the counterweight 24 when there is no passenger in the case of a single counterweight 24. 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, so that the rubber layer is used for shock absorption to prevent the rigidity of the shaft from colliding with the support frame 21.

[0024] The first drive motor is preferably fixed on the counterweight 24, so as to increase 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 at 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 one side of the rotating shaft close to the center of the elevator car 1, and a second gear 26 matching the first gear is provided on the extension, 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 surface where the door gap of the elevator car door is located 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 guide rail 31 in the shape of a rectangular plate, and the two ends of the AI ​​camera second guide rail 31 are fixedly connected to the top of the elevator car through a connecting plate 311. The AI ​​camera second guide rail 31 is parallel to the AI ​​camera 33 car door, and a suspension seat 32 is suspended on the AI ​​camera second guide rail 31, and the AI ​​camera 33 is fixed at the lower end of the AI ​​camera suspension seat 32; the AI ​​camera vision system 3 also includes a second drive motor 34, and the AI ​​camera second drive motor 34 drives the AI ​​camera suspension seat 32, so that the AI ​​camera suspension seat 32 moves along the AI ​​camera second guide rail 31 with the AI ​​camera 33. The elevator control system can judge the distribution of passengers or goods in the car according to the picture taken by the AI ​​camera 33, and can only obtain the picture and make a manual judgment, or it can be judged by a built-in program after obtaining the picture. The AI ​​camera 33 refers to a network intelligent AI camera 33 with a built-in artificial intelligence algorithm chip, which performs language recognition and image recognition on the video data taken by the front-end lens. The AI ​​camera 33 of the present invention adopts the latest AI camera 33, which can improve the accuracy of judgment and reduce the requirements for the computing power of the elevator control system.

[0028] The second guide rail 31 of the AI ​​camera preferably passes through the center of the top of the elevator car of the AI ​​camera 33. So that the two sides of the second guide rail 31 are balanced. Moreover, the second guide rail 31 and the bidirectional screw 35 are preferably arranged symmetrically with the surface where the door gap of the elevator car door is located as the symmetry plane. So that the elevator can also maintain balance during the process of opening and closing the door. The length of the second guide rail 31 of the AI ​​camera is preferably greater than the width of the elevator car door. So that the AI ​​camera 33 can reach a farther position, thereby effectively avoiding the AI ​​camera 33 from being blocked.

[0029] The top of the elevator car preferably includes a top plate and a decorative plate 36 located below the top plate. The AI ​​camera decorative plate 36 is hollowed out at the moving track of the suspension seat 32, the AI ​​camera second guide rail 31 is located above the AI ​​camera decorative plate 36, the width of the AI ​​camera second guide rail 31 is greater than the width of the hollowing of the AI ​​camera 33, the width of the AI ​​camera suspension seat 32 is less than the width of the hollowing of the AI ​​camera 33, and the AI ​​camera 33 is located below the AI ​​camera decorative plate 36. Thus, the hollowing is shielded by the second guide rail 31. The AI ​​camera second drive motor 34 is fixed to the outer top of the elevator car, and the motor shaft of the AI ​​camera second drive motor 34 passes through the top plate and extends between the top plate of the AI ​​camera 33 and the AI ​​camera decorative plate 36. The requirements for the distance between the top plate and the decorative plate 36 can be reduced. In addition, on the one hand, compared with being fixed on the decorative plate 36, the requirements for the load-bearing capacity of the decorative plate 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 for maintenance.

[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 of the two ends of the top of the AI ​​camera hanging seat 32, and a roller is provided on each side of each bracket shaft.

[0031] The visual system also includes a bidirectional screw 35, and an AI camera suspension seat 32 is threadedly connected to each of the two sides of the AI ​​camera bidirectional screw 35; a first gear 341 is sleeved on the motor shaft of the second drive motor 34 of the AI ​​camera, and a second gear 351 is sleeved in the middle of the AI ​​camera bidirectional screw 35, and the first gear 341 of the AI ​​camera 33 engages with the second gear 351 of the AI ​​camera. Preferably, a second extension extending outward in the horizontal direction is provided on each side of the AI ​​camera suspension seat 32, and the AI ​​camera bidirectional screw 35 passes through the two second extensions located on the same side of the two suspension seats 32. The AI ​​camera decorative plate 36 is provided with an upwardly extending flange at the hollow part, and the AI ​​camera 33 flange is used as a guide plate. A roller is installed on the second extension of the AI ​​camera, and the AI ​​camera roller is pressed on the AI ​​camera decorative plate 36. The roller is located on the side of the guide plate away from the hollow. Thus, the roller and the guide plate form a guide structure to make the movement of the camera more stable.

[0032] Yes, there are two bidirectional screws 35, which respectively pass through the second extensions on both sides of the suspension seat 32, and there is only one second drive motor 34 for the AI ​​camera, and the second drive motor 34 for the AI ​​camera synchronously drives the two bidirectional screws 35. Thus, the movement of the camera is 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 goods in the elevator car through the picture in the elevator car taken by the AI ​​camera 33, and preferably the second drive motor 34 controls the AI ​​camera 33 to move on the second guide rail 31, so as to shoot the picture at more than one angle to improve the accuracy of the judgment. For example, a passenger has a cat in his arms, and a single camera or a fixed camera may only be able to shoot the passenger. The present invention can find the cat in the passenger's arms with a greater probability through the movement of the camera, thereby interfering with the judgment of the distribution of each passenger or cargo more accurately. Moreover, some AI cameras 33 have the function of predicting behavior and actions, and such cameras can be used to predict the next behavior of the passenger in advance and adjust the dynamic balance system in advance. For example, if the passenger is expected to get off the elevator, the dynamic balance system can start the first drive motor in advance to make the counterweight move slowly in the direction away from the door, and then move quickly when the passenger gets off the elevator. Preferably, the elevator control system controls the reciprocating motion of the AI ​​camera 33 and shoots the pictures in the elevator car at intervals. The interval here may be a time interval or a distance interval. The distance interval means that pictures are taken at different positions of the second guide rail 31 .
