[0002] A people mover or automated people mover is an unmanned, automated, grade-separated mass transit system. This railway term usually refers to low-capacity rail transport that operates in a small area, such as airports, urban commercial areas or theme parks, but sometimes the term can also be applied to automated but complex rail transport; The APM vehicle moves on the outer wall of the track, so that the APM vehicle transports people, wherein the APM vehicle and the bogie are connected through a damping mechanism. The damping structure refers to a structure that combines damping materials and components into one to consume vibration.

[0003] The inventor discovered the following defects during the operation of the specific embodiment: Damping structures are provided on both sides of the APM vehicle, but the damping structures are not adjustable, so when the weight of a person on one side of the vehicle is heavier, the vehicle will squeeze the damping structure on one side, reducing the resetting effect of the damping structure and affecting the working efficiency of the damping structure.

[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Summary of the invention

[0020] See attached Figure 1-7 , an APM vehicle frame and bogie connection damping mechanism, comprising a bogie body 1, bottom connecting plates 7 are arranged on both sides of the middle top of the bogie body 1, a top connecting plate 6 is arranged just above the bottom connecting plate 7, a connecting spring 5 is arranged between the bottom connecting plate 7 and the top connecting plate 6, a tuned mass damping structure is arranged on the outer wall of the bottom connecting plate 7 and the bottom connecting plate 7, a mounting block 8 is arranged on the top of the top connecting plate 6, a rotating frame 14 is rotatably connected inside the mounting block 8, a reset damper 16 is rotatably connected at the bottom of both ends of the rotating frame 14, and one end of the reset damper 16 is connected to the top of the bogie body 1; A three-way valve 2, wherein the three-way valve 2 is arranged on the top of the bogie body 1, first connecting pipes 3 are arranged on both sides of the three-way valve 2, and a second connecting pipe 4 is arranged on one side of the three-way valve 2; The reset damper 16 includes a shell 1601, which is connected to the bogie body 1 through a spherical universal joint. A cavity 1602 is provided inside the shell 1601. A mounting tube 1603 is provided on the outer wall of the shell 1601. The mounting tube 1603 is connected to the cavity 1602 and is connected to the first connecting tube 3.

[0021] Further, in the above technical solution, the tuned mass damping structure includes a damping ball 9, a sealing ring 10 is provided at the top and bottom of the damping ball 9, one end of the sealing ring 10 is connected to the top connecting plate 6 and the bottom connecting plate 7, the damping ball 9 is set to be spherical, the outer wall of the damping ball 9 is provided with a positioning ring 11, the top of the positioning ring 11 is provided with a mounting rope 13, the bottom of the positioning ring 11 is provided with a connecting damper 12, the number of the connecting dampers 12 is set to multiple, and the multiple connecting dampers 12 are annularly arrayed at the bottom of the positioning ring 11, the Both ends of the connecting damper 12 are provided with spherical universal joints, the connecting damper 12 is connected to the bogie body 1 through the spherical universal joints, the damping ball 9 is connected to the bottom of the vehicle through the positioning ring 11 and the installation rope 13, and the bottom of the damping ball 9 is connected to the bogie body 1 through the connecting damper 12. When the bogie body 1 swings, the bogie body 1 drives the damping ball 9 to swing in the opposite direction through the installation rope 13, and then the damping ball 9 squeezes and stretches the connecting dampers 12 at different positions. At the same time, the opposite direction swing of the damping ball 9 can neutralize the swing of the vehicle and reduce the swing amplitude of the vehicle.

[0022] Furthermore, in the above technical solution, a through hole is opened in the middle of the damping ball 9, and a gap is arranged between the through hole in the middle of the damping ball 9 and the top connecting plate 6 and the bottom connecting plate 7. The damping ball 9 is arranged in a spherical shape, and the damping ball 9 is connected to the top connecting plate 6 and the bottom connecting plate 7 through a sealing ring 10. The sealing ring 10 is made of rubber material, so that the damping ball 9 is elastically connected to the top connecting plate 6 and the bottom connecting plate 7.

[0023] Furthermore, in the above technical solution, mounting plates 15 are provided on both sides of the top of the rotating frame 14, and the top of the mounting plates 15 is connected to the vehicle frame.

[0025] In this embodiment, when a person gets on the APM carriage, the door on one side of the APM carriage is opened, and the person enters the APM carriage through the opened door. When the person enters the APM carriage, the rotating frame 14 on one side is squeezed, and the rotating frame 14 squeezes the bottom connecting plate 7 through the top connecting plate 6, so that the bottom connecting plate 7 drives the rotating frame 14 to move downward, and at the same time, the rotating frame 14 moves the pressure rod 1604 downward, so that the pressure rod 1604 drives the sliding ring 1605 to slide downward on the inner wall of the cavity 1602. When the pressure sensor detects that the downward pressure of the rotating frame 14 is large, the air pump draws gas into the interior of the three-way valve 2 and pumps it into the interior of the cavity 1602 through the first connecting pipe 3, thereby increasing the pressure inside the cavity 1602, reducing the downward movement amplitude of the sliding ring 1605, and drawing out the gas inside the cavity 1602 on the other side to reduce the pressure inside the cavity 1602 on the other side, thereby keeping the APM carriage balanced, and at the same time, the pressure in a reset damper 16 can be controlled separately; During the operation of the APM car, the APM car will vibrate, and the vibration is transmitted to the damping ball 9 through the installation rope 13, so that the movement direction of the damping ball 9 is opposite to the movement direction of the APM car, thereby reducing the vibration of the APM car, and the damping ball 9 stretches and squeezes the connection dampers 12 at different positions.
