Description

Technical Field

[0001] This invention relates to the field of urban rail transit technology, and in particular to a rail transit door system. Background Technology

[0002] Rail transit door panels are installed on urban rail transit trains to cover the side entrances and exits of the train body. With the increase in train speed and the requirements for the interior space and the aesthetic appearance of the train, the shape of the train body has changed significantly. Traditional door panels have the same upper and lower swing distance when opened, which cannot be used for the current diverse train body shapes and platform environments. The shape of the current train body requires the upper part of the door panel to swing out a larger distance, but the platform space limits the lower part of the door panel to swing out a larger distance. Summary of the Invention

[0003] Purpose of the invention: In view of the above problems, the purpose of this invention is to provide a rail transit door system that allows the door to swing out at different heights after the door is opened.

[0004] Technical Solution: This invention proposes a rail transit door system, including a door frame, a door leaf, a load-bearing drive mechanism, and a locking device. The door frame is installed at the vehicle entrance. When the door leaf is closed and locked, the door frame and door leaf achieve a seal of the door system. The load-bearing drive mechanism is installed on the upper part of the vehicle entrance and is located above the door frame, providing power output for the opening and closing of the train door. An upper guide rail is provided on the load-bearing drive mechanism to guide the upper part of the door leaf. The locking device is installed on the side of the vehicle entrance to control the opening and closing state of the door leaf. When the door leaf is open, the upper and lower parts of the door leaf can achieve different amounts of obstruction.

[0005] The load-bearing drive mechanism is also equipped with a door carrier, and the upper part of the door leaf is installed on the door carrier. The door carrier is equipped with rollers. Through the rollers, the door carrier drives the door leaf to move along the upper guide rail, thereby realizing the opening and closing action of the door system.

[0006] When the upper guide rail is installed at different positions on the load-bearing drive mechanism, the upper part of the door leaf has different protrusion amounts.

[0007] The door system also includes a lower swing arm, which is installed on the lower side of the vehicle entrance. A lower guide rail is provided at the bottom of the door panel. The lower swing arm and the lower guide rail guide the lower part of the door panel.

[0008] The amount of the door leaf protruding from the bottom is achieved by changing the curvature of the end surface of the lower guide rail.

[0009] The door system also includes an emergency unlocking device, which is fastened to the vehicle body with bolts and connected to the locking device by a steel wire rope to enable unlocking in an emergency. The emergency unlocking device includes an external emergency unlocking device and an internal emergency unlocking device, which are installed inside and outside the vehicle respectively, and can be used to unlock in an emergency from both the inside and the outside.

[0010] Beneficial effects: Compared with the prior art, the significant advantages of this invention are: This invention can achieve different amounts of the upper and lower parts of the door leaf, making it more suitable for different vehicle body shapes and operating environments. When the upper or lower part of the door leaf needs to be adjusted, it is only necessary to adjust the installation position of the upper guide rail above the door leaf or change the curvature of the curved block of the lower guide rail at the bottom of the door leaf. There is no need to redesign the door leaf or the connection structure of the vehicle body relative to the installation of the door leaf, which is more convenient and faster, and generates greater economic benefits.

[0012] Figure 2 This is a schematic diagram of the upper and lower insertion strokes of the present invention when the door is open;

[0013] Figure 3 This is a schematic diagram of the lower guide rail structure of the present invention. Detailed Implementation

[0014] like Figure 1-2 The present invention discloses a rail transit door system, comprising a door frame 5, a door leaf 2, a load-bearing drive mechanism 1, and a locking device 6. The door frame 5 is installed at the vehicle entrance. When the door leaf 2 is closed and locked, the door frame 5 and the door leaf 2 achieve a seal of the door system. The load-bearing drive mechanism 1 is installed on the vehicle body and is located above the door frame 5. An upper guide rail 10 is provided on the load-bearing drive mechanism 1 to guide the upper part of the door leaf 2. The locking device 6 is installed on the side of the vehicle entrance to control the opening and closing state of the door leaf 2. When the door leaf 2 is opened, the upper and lower parts of the door leaf 2 achieve different amounts of insertion.

[0015] The load-bearing drive mechanism 1 is also equipped with a door carrier 9. The upper part of the door leaf 2 is mounted on the door carrier 9, which is equipped with rollers. Through the rollers, the door carrier 9 drives the door leaf 2 to move along the upper guide rail 10, realizing the opening and closing action of the door system. The upper part of the door leaf 2 has different protrusion amounts depending on the position of the upper guide rail 10 on the load-bearing drive mechanism 1. The door system also includes a lower swing arm 7, which is installed on the side of the vehicle entrance, slightly below the center. A lower guide rail 8 is provided at the bottom of the door leaf 2. The lower swing arm 7 and the lower guide rail 8 provide guidance for the lower part of the door leaf 2. The protrusion amount of the lower part of the door leaf 2 is achieved through the curved surface design of the lower guide rail 8. Figure 3 The lower guide rail consists of a plane c and an end curved surface d.

[0016] like Figure 2 In the diagram, the solid line represents the closed position of door leaf 2, the dashed line represents the open position of door leaf 2, a is the amount of the upper part of door leaf 2 pushed out, and b is the amount of the lower part of door leaf 2 pushed out.

[0017] The door system also includes an emergency unlocking device, which is fastened to the vehicle body with bolts and connected to the locking device 6 by a steel wire rope to enable unlocking in an emergency. The emergency unlocking device includes an external emergency unlocking device 4 and an internal emergency unlocking device 3, which are installed inside and outside the vehicle respectively, and can be unlocked from both the inside and outside.
