Society is paying increasing attention to people with disabilities, the elderly, pregnant women, and those with mobility difficulties such as carrying large luggage. Ensuring their barrier-free travel in public transportation has become an important goal of urban transportation construction.

[0003] When a train arrives at a station, there will be a gap between the train and the platform. At this time, step stools are needed to help people with disabilities board the train. However, the height of the train door and the distance between the platform are different for different train models. Most of the existing step stools can only be placed stably on the doors of the same type of train and cannot be placed stably between the doors of different types of trains and the platform. This means that different accessible step stools need to be prepared for different types of trains, which is time-consuming, labor-intensive, increases labor costs, requires the preparation of multiple different accessible step stools, and also causes unnecessary waste.

[0004] Therefore, an auxiliary mechanism for barrier-free mobility in rail transit is proposed to solve the problems mentioned above. Utility Model Content

This solves the problem that most existing ramps can only be stably placed on the same type of train door, and cannot be stably placed between different types of train doors and the platform. This leads to the need to prepare different barrier-free ramps for different types of trains, which is time-consuming, labor-intensive, increases labor costs, requires the preparation of multiple different barrier-free ramps, and causes unnecessary waste.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 4 An auxiliary mechanism for barrier-free mobility in rail transit according to this embodiment includes an auxiliary plate 1, a movable plate 2 fixedly connected to the bottom of the auxiliary plate 1, a hollow plate 3 provided below the movable plate 2, and an auxiliary plate 4 hinged to the side of the auxiliary plate 1.

[0026] A sleeve 7 is fixedly connected to the side of the hollow plate 3. An adjustment mechanism is provided on the hollow plate 3 through the sleeve 7. The adjustment mechanism includes a sliding rod 9 for limiting, a piston 8 and a spring 10.

[0027] A limiting plate 12 is fixedly connected to one side of the movable plate 2, and a support component is provided on the movable plate 2 through the limiting plate 12;

[0028] When it is necessary to place accessible steps on doors of different heights, the sliding bar 9 is pulled to move the movable plate 2 up or down inside the hollow plate 3. When it reaches the appropriate position, the position of the hollow plate 3 and the movable plate 2 is fixed by the adjustment mechanism.

[0029] When the auxiliary plate 1 is adjusted to the appropriate position, the movement of the moving plate 2 will cause the support component to swing the auxiliary plate 4 up and down. After the position of the auxiliary plate 1 is fixed, the bottom of the auxiliary plate 4 is attached to the ground by adjusting the support component. Then the support structure is fixed to support the auxiliary plate 4 and make the auxiliary plate 4 more stable.

[0030] At this point, the barrier-free ramps were placed smoothly on all types of trains without the need for additional ramps of other types, reducing material waste. At the same time, staff no longer needed to frequently change the ramps, reducing the difficulty of the work, improving work efficiency, and reducing work time.

[0031] A trapezoidal groove 5 is provided on one inner wall of the hollow plate 3. A trapezoidal slide rail 6 is slidably connected to the inner wall of the trapezoidal groove 5. One side of the trapezoidal slide rail 6 is fixedly connected to the side of the movable plate 2. Several circular grooves 11 are provided on the other side of the trapezoidal slide rail 6.

[0032] Piston 8 is located inside sleeve 7 and is slidably connected to sleeve 7. Slide rod 9 passes through sleeve 7 and is slidably connected to sleeve 7. Slide rod 9 is fixedly connected to piston 8.

[0033] The slide rod 9 passes through the hollow plate 3 and is slidably connected to the hollow plate 3. One end of the slide rod 9 extends into the circular groove 11. The spring 10 is located inside the sleeve 7. One side of the piston 8 is fixedly connected to one end of the spring 10, and the other end of the spring 10 is fixedly connected to the inner wall of the sleeve 7.

[0034] When it is necessary to place the accessible platform smoothly between different types of trains and platforms, pull the slide bar 9, and the piston 8 slides in the sleeve 7 to remove the slide bar 9 from the circular groove 11. At this time, the spring 10 is in a compressed state, and the fixation between the moving plate 2 and the hollow plate 3 is released. Through the limiting of the trapezoidal slide groove 5 and the trapezoidal slide rail 6, the moving plate 2 is moved up or down. When it reaches the appropriate position, the slide bar 9 is released. Under the reset action of the spring 10, the piston 8 will drive the slide bar 9 to return to its original position, and the slide bar 9 will be locked into the circular groove 11 to fix the position between the moving plate 2 and the hollow plate 3.

[0035] At this point, the position of auxiliary plate 1 was adjusted so that it could be placed stably between doors and platforms at different heights, improving convenience and reducing labor costs.

[0036] The support assembly includes a groove 13 formed on one side of the limiting plate 12, a slider 14 slidably connected to the inner wall of the groove 13, and a connecting plate 15 fixedly connected to one side of the slider 14.

[0037] One end of the connecting plate 15 is rotatably connected to a wheel 16, and an arc-shaped groove 17 is provided on one side of the auxiliary plate 4, which is adapted to the wheel 16.

[0038] A limiting rod 18 is inserted into the other side of the connecting plate 15. The limiting rod 18 is slidably connected to the connecting plate 15. Several limiting holes 19 are opened on the other side of the limiting plate 12. The limiting rod 18 extends into the limiting hole 19. A second spring 20 is provided inside the connecting plate 15. One end of the second spring 20 is fixedly connected to the other end of the limiting rod 18, and the other end of the second spring 20 is fixedly connected to the inner wall of the connecting plate 15.

[0039] After adjusting the position of auxiliary plate 1, pull the limiting rod 18 to disengage it from the limiting hole 19. At this time, spring 20 is in a compressed state. Since wheel 16 is compatible with arc groove 17, the connecting plate 15 is moved downward or upward by the limiting of sliding groove 13 and slider 14. Wheel 16 will drive auxiliary plate 4 to swing through arc groove 17. When the bottom of auxiliary plate 4 touches the ground, release the limiting rod 18. Under the reset action of spring 20, the limiting rod 18 will be locked into the limiting hole 19. At this time, the positions of connecting plate 15 and limiting plate 12 are fixed. At the same time, wheel 16 will support the position of auxiliary plate 4.

[0040] At this point, the adjustment of placing the bottom of auxiliary plate 24 on the ground is complete, and the position of auxiliary plate 24 will also be supported, making auxiliary plate 24 more stable.

[0041] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0042] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
