One end of the bar 206 is connected to a slider 207, which is slidably mounted within the fixed strip 201 via a slide groove 203. A sliding wheel 209 is rotatably mounted on the slider 207 via bolts. The sliding wheel 209 is positioned within two protrusions 202 on the fixed strip 201. The front surface of the slider 207 is fixedly connected to a second connecting bar 210, which is fixedly connected to a fixing plate 211 via hexagonal bolts. A set of first pulleys 215 are connected to the first rotating shaft 217 of the first motor 216 at both ends of the screw rod 204. The first belt 214 is mounted on the first pulleys 215, and the first motor 216 is fixedly connected to both ends of the main body 1. In this arrangement, the automatic switch mechanism 2 has a simple structure and does not open or close too quickly, reducing the probability of passenger injury.

[0024] like Figures 1 to 6As shown, in a specific embodiment, an inner door 3 is provided below the main body 1, and a fixing plate 211 is fixedly connected to the inner door 3 by a hexagonal bolt 212. In this arrangement, the inner door 3 is fixedly connected to the fixing plate 211 by the hexagonal bolt 212, and the hexagonal bolt 212 and the fixing plate 211 make the connection more stable.

[0025] like Figures 1 to 6 As shown, in a specific embodiment, an outer door 4 is provided below the main body 1, and the size of the inner door 3 is smaller than that of the outer door 4. In this arrangement, the outer door 4 prolongs the service life of the inner door 3.

[0026] like Figures 1 to 6 As shown, in a specific embodiment, a base 5 is further provided under the main body 1, and a conveying mechanism 6 is provided in the base 5. The conveying mechanism 6 includes a conveying box 601, a fixed rod 602, a rotating sleeve 603, a second belt 604, a second pulley 605, a second motor 606, a second rotating shaft 607, a conveyor belt 608, a slide 609 and a handle 610. The fixed rod 602 is fixedly installed in the conveying box 601, and the rotating sleeve 603 is rotatably installed on the fixed rod 602. A second motor 606 is installed inside the conveying box 601, and the second rotating shaft 607 of the second motor 606 and the rotating sleeve 603 are connected to the second pulley 605. The second belt 604 is sleeved on the second pulley 605, and the conveyor belt 608 is sleeved on the rotating sleeve 603. Two slides 609 are connected to the bottom of the conveying box 601, and a handle 610 is connected to the front side of the conveying box 601. In this arrangement, the conveying mechanism 6 makes it easier for passengers with limited mobility to get on the bus, thereby improving the efficiency of passengers getting on the bus and saving manpower.

[0027] like Figures 1 to 6 As shown, in a specific embodiment, a notch is provided on the inner bottom of the base 5. In this arrangement, the notch makes it easy to extract the conveying mechanism 6 when in use.

[0028] like Figures 1 to 6 As shown, further, the shape of the transport box 601 is triangular. In this arrangement, the shape of the transport box 601 is triangular to provide better stability.

[0029] The implementation principle of the fully opening and closing door of the platform after a passenger with limited mobility gets on the bus in this embodiment is as follows: when a passenger with limited mobility needs to get on the bus, the button is started, the first rotating shaft 217 on the first motor 216 rotates, causing the first pulley 214 fixedly connected to the rotating shaft 217 to rotate, and the first pulley 214 drives the first pulley 214 on the screw rod 204 to rotate. The screw rod 204 is rotatably installed in the main body 1 through the fixed sleeve. The rotation of the screw rod 204 causes the circular sleeve 205 on the screw rod 204 to move to the left. A first connecting strip 206 is provided on the circular sleeve 205, and a slider 207 is connected to the first connecting strip 206. The slider 207 is fixed with two sliding wheels 209 by bolts, and the sliding wheels 209 are stuck in the protrusions 202 in the fixed strip 201. On the upper side, the surface of the slider 207 is connected with a second connecting bar 210, and a fixing plate 211 is provided on the second connecting bar 210. The inner door 3 is connected to the fixing plate 211 and the second connecting bar 210 by a hexagonal bolt. The circular sleeve 205 moves to the left, driving the inner door 3 to move to the left. At this time, the inner door 3 is in the open state. A notch is provided in the base 5. A slide bar 609 is connected to the bottom of the conveying mechanism 6. The conveying mechanism 6 is pulled out from the notch in the base 5 through the slide bar 609 at the bottom, and the passenger is placed on the conveyor belt 608 on the conveying mechanism 6. The second rotating shaft 607 of the second motor 606 rotates, causing the second pulley 605 on the second rotating shaft 607 to rotate, driving the second pulley 605 on the rotating sleeve 603 to rotate, causing the conveyor belt 608 to rotate, and allowing the passenger to move onto the car.
