The limit mechanism 2 comprises an upper fixed support 21, an upper limit arm 22, a lower limit arm 23 and a lower fixed support 24, wherein the upper fixed support 21 is arranged on two sides of the opening top of the stepping decorative plate 1, and the first end of the upper limit arm 22 is hinged with the upper fixed support 21; the first end of the lower limiting arm 23 can slide along the length direction of the upper limiting arm 22, the second end of the lower limiting arm 23 is hinged with the lower fixed support 24, and the lower fixed support 24 is symmetrically arranged at two ends of the outer side of the pedal body 5.

In one embodiment, the moving assembly comprises a first rotating rod 43, a second rotating rod 44, a first moving rod and a second moving rod, a rotating shaft is assembled on the bottom plate of the turnover guide rail 42, the stepping motor 3 drives the rotating shaft to rotate, and the first end of the first rotating rod 43 is assembled on the rotating shaft through a bearing and rotates along with the rotating shaft; the second end of the first rotating lever 43 is hinged to the first end of the second rotating lever 44, the second end of the second rotating lever 44 is hinged to the first end of the first moving lever, and the second end of the first moving lever is hinged to the second moving lever.

In one embodiment, the turnover guide rail 42 is provided with a main slideway and a branch slideway, and the middle upper part of the main slideway is communicated with the arc-shaped branch slideway; the first sliding column at the hinged position of the first moving rod and the second moving rod can slide in the main slideway and the branch slideway, the second sliding column is arranged at the second end of the second moving rod, and the second sliding column can slide in the main slideway.

In one embodiment, the step attachment bracket 46 is hinged to the first slide post.

In one embodiment, a hollow chute is provided in the middle of the upper limiting arm 22, and the first end of the lower limiting arm 23 is slidably assembled in the hollow chute through a sliding bearing.

The integrated automatic overturning boarding step has the following working principle:

When a driver needs to get on (off) the car, when the driver presses the step opening command, the step motor 3 rotates (the corresponding step motor 3 is controlled to work and react by the corresponding button in the main cab, which is a conventional mature technology for the prior art, so that the connection mode between the step opening and step closing command and the step motor 3 is not repeated here any more), and the motion executing mechanism 4 is driven to move. The I point on the stepping connecting support 46 translates from the a point to the b point (the II point correspondingly translates from the b point to the c point) on the turnover guide rail 42, so as to drive the pedal body 5 to translate (figures 2-3 and 5); as the stepping motor 3 continues to rotate, the point II on the stepping connection bracket 46 rotates around the point of the turnover guide rail 42c, driving the pedal body 5 to turn over. After the step connection bracket 46 rotates to the point d of the turning guide rail 42, the stopper II on the connection bracket is clamped on the guide rail, and the turning operation is stopped, and the pedal body 5 is in a horizontal posture (fig. 7 and 8) in which the user can step on the vehicle.

Under the action of the motion executing mechanism 4, the pedal body 5 translates first and then overturns, so that the pedal body 5 and the stepping body interfere when the pedal body is directly overturned, the gap between the pedal body and the stepping body can be reduced, and the attractiveness is improved.

During the movement of the step connection bracket 46, the limit mechanism 2 starts to move synchronously: the upper end of the upper limit arm 22 is fixed on the upper fixed support 21 and rotates around the point e; the lower end of the lower limiting arm 23 is fixed on the lower fixed support 24 and rotates around the g point (fig. 6). The upper end of the lower stopper arm 23 slides in the guide rail of the upper stopper arm 22. When the pedal is turned to a trample horizontal posture, the upper end of the lower limiting arm 23 slides to the bottom of the guide rail of the limiting arm, and at the moment, the upper limiting arm 22 and the lower limiting arm 23 are arranged in a straight line, so that a stretching limiting effect is achieved.

When the driver gets on and off the vehicle, the stepping motor 3 rotates in the opposite direction when the stepping closing command is pressed, the stepping connection bracket 46 rotates around the turning guide 42c point first, and then translates from b point to a point along the guide. The pedal body 5 is synchronously retracted from the stepping posture to the closed state (fig. 9).
