[0002] Accessible bus ramps are special devices installed on buses to facilitate boarding and alighting for people with disabilities, the elderly, children, and other passengers with mobility impairments.

[0003] In existing technologies, bus steps and bus side doors are mostly fixed by welding or bolting. Welding makes the steps a non-removable integral structure, which requires destructive disassembly for maintenance, greatly increasing the difficulty of maintenance. While bolting provides removability, it requires frequent tightening of bolts to complete installation and disassembly, which is not only cumbersome and time-consuming, but also aggravates thread wear due to repeated operation, thus reducing the convenience of operation.

[0015] 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.

[0016] Please see Figure 1-3 The present invention provides the following technical solution:

[0017] A barrier-free bus step connection device includes a step 1 with multiple limiting grooves 3 and a quick-release mechanism 2. The quick-release mechanism 2 includes a rotating ring 21 and a mounting base 22. A first spring 23 is symmetrically arranged and fixedly connected inside the rotating ring 21. A limiting rod 24 is slidably connected inside the rotating ring 21 at a position corresponding to the first spring 23. A rotating rod 25 is fixedly connected to the bottom end of the rotating ring 21. A pressing rod 26 is fixedly connected to the rotating rod 25 at a position corresponding to the inside of the mounting base 22. A limiting seat 27 is symmetrically arranged and slidably connected inside the mounting base 22. A sliding groove 28 is provided inside the mounting base 22 at a position corresponding to the top of the limiting seat 27. A second spring 29 is fixedly connected inside each sliding groove 28. A connecting block 201 is fixedly connected to the top of the limiting seat 27 at a position corresponding to the sliding groove 28.

[0018] The rotating ring 21 is rotatably connected to the middle position of the pedal 1. The rotating ring 21 has a lever groove. The mounting base 22 is fixedly connected to the middle position of the bottom end of the pedal 1. The lever groove makes it easy for the operator to rotate the rotating ring 21 with the help of external tools. One end of the second spring 29 is fixedly connected to the corresponding connecting block 201. The second spring 29 is in a contracted state. The second spring 29 can drive the limiting seat 27 to reset through the connecting block 201. The connecting block 201 is slidably connected inside the corresponding slide groove 28. The bottom end of the rotating rod 25 rotates through the pedal 1 and the top of the mounting base 22 and is fixedly connected to the pressing rod 26. The pressing rod 26 is located inside the mounting base 22 at the middle position of the two limiting seats 27. Both ends of the pressing rod 26 are arc-shaped. One end of the limiting rod 24 is arc-shaped. The other end of the limiting rod 24 is fixedly connected to the corresponding first spring 23. The arc-shaped end of the limiting rod 24 is slidably inserted into the corresponding limiting groove 3.

[0019] In use, when it is necessary to release the pedal 1, an external tool can be inserted into the leverage groove on the rotating ring 21, and then the rotating ring 21 can be rotated forcefully. The rotating ring 21 will drive the two limiting rods 24 to rotate together. When the limiting rods 24 rotate, their arc-shaped parts will press against the inner wall of the connected limiting groove 3. At this time, as the rotating ring 21 rotates, the limiting rods 24 will be passively squeezed back into the interior of the rotating ring 21 by the inner wall of the limiting groove 3. The retraction of the limiting rods 24 will compress the first spring 23. At this time, the limiting rods 24 are completely retracted into the interior of the rotating ring 21 and no longer provide support for the rotating ring 21 and the rotating rod 25. When the limit switch is activated, the rotating ring 21 rotates, which in turn drives the rotating rod 25 to rotate. The rotating rod 25 then drives the pressing rod 26 to rotate. After the pressing rod 26 rotates 180° inside the mounting base 22, it no longer presses against the two limit seats 27. At this point, the limit seats 27 are no longer pressed by the pressing rod 26, and the second spring 29 will drive the limit seats 27 to reset through the connecting block 201. The limit seats 27 will retract into the mounting base 22. With the limit seats 27 retracted, the top walls of the limit seats 27 no longer abut against the bottom of the bus floor. The limit of pedal 1 is released, allowing pedal 1 to separate from the bus floor. Figure 2 When fixing pedal 1, hold pedal 1 so that it corresponds to the pre-reserved installation position on the bus floor. Then, make the mounting seat 22 at the bottom of pedal 1 penetrate the bottom wall of the bus. Then, make the rotating ring 21 drive the limiting rod 24 to rotate to the corresponding limiting groove 3. When the limiting rod 24 corresponds to the limiting groove 3, the first spring 23 will reset and drive the limiting rod 24 to insert into the corresponding limiting groove 3. At the same time, the rotating ring 21 will also drive the pressing rod 26, so that the pressing rod 26 will press the two limiting seats 27 again, so that the limiting seats 27 protrude from the mounting seat 22. The top of the protruding limiting seats 27 abuts against the bottom of the bus floor. At this time, pedal 1 is fixed. The operation is extremely convenient and meets the needs of efficient bus maintenance and convenient operation.
