the pedal assembly comprises a first sub pedal and a second sub pedal which are rotatably connected with the mounting frame, the first sub pedal is in transmission connection with the second sub pedal, and when the first sub pedal and the second sub pedal are controlled to rotate, the first sub pedal and the second sub pedal can be switched between a first state and a second state, in the first state, the first sub pedal and the second sub pedal are accommodated in the accommodating cavity, in the second state, the first sub pedal and the second sub pedal are outwards turned out of the accommodating cavity and are arranged in a step shape; and
the driving assembly comprises a driver and a transmission mechanism which are in transmission connection, and the transmission mechanism is in transmission connection with any one of the first sub pedal and the second sub pedal.
2. The stepping mechanism of claim 1, wherein a linkage is rotatably coupled between the first sub-pedal and the second sub-pedal.
3. The stepping mechanism of claim 1, wherein said mounting bracket comprises a first bracket having an opening for said first sub-pedal and said second sub-pedal to pass through, and a second bracket laterally connected to a side of said first bracket facing away from said opening and connected to said transmission mechanism.
4. The stepping mechanism according to claim 3, wherein said first sub-pedal is rotatably connected to said first bracket, said second sub-pedal is rotatably connected to said second bracket, said first sub-pedal is received in said first bracket and said second sub-pedal is received in said second bracket in said first state;
and/or in the first state, the first sub pedal is located at the outer side of the second sub pedal, the surface of the first sub pedal, which is away from the second sub pedal, does not protrude from the edge of the opening, and in the second state, the second sub pedal is arranged at intervals with the first sub pedal and is located above the first sub pedal.
5. The stepping mechanism of any one of claims 1-4, wherein the mount assembly further comprises a first stop secured to the mount, the first stop being configured to limit an overturning angle of any one of the first sub-pedal and the second sub-pedal during switching of the first state and the second state.
6. The stepping mechanism according to claim 5, wherein the first stopper includes a first stopper and a second stopper, the first stopper is fixedly connected with the mounting frame, the second stopper is laterally connected to a side of the first stopper facing away from the mounting frame, and is formed with an abutment surface facing the opening, and a avoidance gap extending toward the opening, in the first state, any one of the first sub-pedal and the second sub-pedal abuts against the abutment surface, and in the second state, any one of the first sub-pedal and the second sub-pedal is engaged into the avoidance gap;
and/or, the fixing frame assembly further comprises a second limiting piece, and the second limiting piece is arranged on any one of the mounting frame, the first sub pedal and the second sub pedal, so that when the fixing frame assembly is in a first state, the distance between the first sub pedal and/or the second sub pedal and the mounting frame is limited.
7. The stepping mechanism according to claim 1, wherein said transmission mechanism comprises a gear shaft and a transmission gear, which are meshed with each other, said gear shaft being in transmission connection with said driver, said transmission gear being fixedly connected with either one of said first sub-pedal and said second sub-pedal;
and/or the driver is a motor.
8. The stepping mechanism of claim 1, further comprising a control assembly disposed on said mounting frame and electrically connected to said actuator.
9. The stepping mechanism of claim 8, wherein said control assembly comprises a controller and an electric switch, said controller being connected to said electric switch and controlling the actuation of said actuator in response to a signal from said electric switch.
10. The stepping mechanism of claim 9, wherein the control assembly further comprises a position sensor and a hand brake sensor connected to the controller, wherein the position sensor is mounted on the mounting frame and is disposed near the pedal assembly, the hand brake sensor is used for monitoring a pulled-up state and a released state of the hand brake in real time, and when the hand brake sensor monitors and transmits a signal that the hand brake is in the released state, the controller receives the corresponding signal and drives the pedal assembly to be accommodated in the accommodating cavity to be in the first state.
11. The stepping mechanism of claim 10, wherein said control assembly further comprises a buzzer connected to said controller, such that said controller controls said buzzer to alarm during said first state switching to said second state, and wherein said controller controls said buzzer to cease to alarm when said pedal assembly is in said second state and triggers said position sensor.
12. A van comprising a stepping mechanism as claimed in any one of claims 1 to 11.
13. The van of claim 12, wherein said van includes a frame, said step mechanism is disposed at a bottom of said frame, and in said first state, said step mechanism does not protrude from said frame, and in said second state, said step assembly protrudes from said frame;
and/or the stepping mechanism is positioned at the side part of the frame.
