The first embodiment comprises a power mechanism, which is used to make the two door arms 11 rotate symmetrically between the door closing position and the door opening position; when the door arm 11 rotates to the door closing position, the two doors approach and abut against each other, and the inner walls of the doors abut against the bottom plate of the shuttle bus to close the shuttle bus, and the baffle 20 is completely shielded under the base plate 10; when the door arm 11 rotates to the door opening position, the two doors move away from each other, and there is a gap between the doors and the bottom plate of the shuttle bus, and the baffle 20 is clamped in the gap between the doors and the bottom plate of the shuttle bus.

[0028] The anti-stepping-in-the-air mechanism for a shuttle bus provided in the present embodiment provides a structural foundation for installation by setting a base plate 10, and enables the door arm 11 to rotate between a door-opening position and a door-closing position by setting a door arm 11 and a power mechanism, thereby driving the door to open or close; a baffle 20 is set horizontally in the gap between the door and the shuttle bus, and is located above the door arm 11. When the door arm 11 is rotated to the door-opening position, the baffle 20 is used to make up for the gap between the door and the shuttle bus, and to block the door arm 11. Even if a passenger steps on the door by mistake, he or she will only step on the baffle 20, thereby effectively preventing the passenger from stepping in the air or being pinched by mistake on the door arm 11.

[0029] In order to further explain the specific structure of the power mechanism, the power mechanism includes a double-headed motor 30, a pair of screws 31, a pair of sliders 32, a pair of racks 33 and a pair of gears 34; the double-headed motor 30 is fixedly connected to the base plate 10, and the two screws 31 are coaxially connected to the two ends of the output shaft of the double-headed motor 30, and the threads of the two screws 31 are opposite in direction; the two sliders 32 are respectively screwed to the two screws 31, and respectively slide with the base plate 10 along the axial direction of the screw 31; the two racks 33 are respectively arranged on the two sliders 32, and both extend along the axial direction of the screw 31; the two gears 34 are respectively rotatably arranged on the hinge shafts of the two door arms 11, and are fixedly connected to the corresponding door arms 11, and the two gears 34 are respectively meshed with the two racks 33.

[0030] Through the above arrangement, the double-headed motor 30 is utilized to simultaneously and synchronously drive the two screw rods 31 to rotate, thereby driving the two sliders 32 to slide, thereby driving the two racks 33 to slide, thereby driving the gear 34 to rotate through the meshing of the rack 33 and the gear 34, thereby driving the door arm 11 to rotate through the fixed connection between the gear 34 and the door arm 11, so that the door arm 11 rotates between the door opening position and the door closing position.

[0031] In order to further explain the sliding fit between the slider 32 and the base plate 10 , a pair of slide grooves 12 are provided on the bottom surface of the base plate 10 , and the slide grooves 12 extend along the axial direction of the screw rod 31 ; the two sliders 32 are slidably connected to the base plate 10 through the two slide grooves 12 .

[0032] In order to keep the vehicle door parallel to the vehicle body at all times when the door arm 11 rotates between the open position and the closed position, the anti-stepping mechanism for the shuttle bus also includes a pair of parallel arms 13, and the length of the parallel arms 13 is the same as the length of the door arm 11; the two parallel arms 13 respectively correspond to the two door arms 11, and are arranged parallel to the corresponding door arms 11, and the two ends of the parallel arms 13 are respectively twisted with the base plate 10 and the corresponding door shaft.

[0033] In order to further ensure the structural performance, a connecting rod 14 is axially connected between the middle part of the parallel arm 13 and the middle part of the corresponding door arm 11 .

The limit frames 15 have a slot 151 on the side facing the vehicle door, and the slot width of the slot 151 matches the thickness of the baffle 20; when the door arm 11 is in the door-opening position, the side of the baffle 20 away from the vehicle door is inserted into the corresponding slot 151.

[0035] Through the above arrangement, when in the door opening position, the inner side of the baffle 20 is inserted into the slot 151. Since the slot width and thickness match, the limit frame 15 will provide longitudinal structural support for the baffle 20, thereby further improving the supporting performance of the baffle 20 when being stepped on.

[0036] In order to prevent the baffle 20 from making unnecessary hard contact with the bottom of the slot 151 , which may cause damage to the baffle 20 or the vehicle body, an elastic buffer layer 152 is provided at the bottom of the slot 151 .

[0037] In order to facilitate the insertion of the baffle plate 20 into the slot 151 , the side of the baffle plate 20 away from the vehicle door is designed in a wedge shape.
