Further, a foot board 12 is provided below the frame. Specifically, after the baby carriage is switched to the electric power assisting state, feet leave the ground, the pedals are convenient to tread, and the comfort of the baby carriage is improved. Further, as shown in fig. 3, fig. 4 and fig. 5, which are a schematic structural diagram of the matching between the fixed seat and the knob of the electric power-assisted and sliding-step dual-purpose stroller of the present invention, a schematic structural diagram of a cross-section a-a in fig. 3, and a schematic structural diagram of the fixed seat, the switching mechanism includes an elastic component 81, a fixed seat 82, and a knob 83, an upper end of the elastic component is connected to the stroller frame, a lower end of the elastic component is connected to the motor, a rotating shaft 821 is vertically disposed outside the fixed seat, a through hole 831 is disposed in a center of the knob, the rotating shaft is inserted into the through hole of the knob, the knob can freely rotate around the rotating shaft and freely slide along a length direction of the rotating shaft, a sliding rod 832 is disposed at an edge of the knob and extends towards the direction of the fixed seat, a shift lever 833 is disposed at a free end of the sliding rod and extends along the length direction of the sliding rod, a diameter of the sliding rod is smaller than a diameter of the shift lever, and an arc-shaped chute 822 is disposed on the fixed seat and adapted to the sliding rod, the two ends of the arc-shaped sliding groove are respectively provided with a limiting groove 823 matched with the shifting rod, the sliding rod is inserted into the sliding groove and then forms sliding fit with the sliding groove, and the shifting rod shifts the motor to enable the motor to swing relative to the frame. Specifically, when the electric power assisting device is in an electric power assisting state, the shifting rod on the knob is located in the limiting groove far away from the motor, the shifting rod is located in the center of the limiting groove, due to the limiting effect of the limiting groove on the shifting rod, the knob cannot rotate at the moment, the shifting rod is not in contact with the motor, the motor is clockwise deflected under the upward pulling of the elastic component, and at the moment, the power wheel on the motor is in contact with the rear wheel of the vehicle and transmits power for the rear wheel of the vehicle. When the electric power-assisted state is required to be switched to the sliding step state, the knob is pushed forwards firstly, the sliding rod is located in the center of the limiting groove, then the knob is rotated anticlockwise, the sliding rod moves anticlockwise to the limiting groove close to the motor along the arc-shaped sliding groove, then the shifting lever is located in the center of the limiting groove, the knob cannot rotate due to the limiting effect of the limiting groove on the shifting lever, the shifting lever is in contact with the motor at the moment and pushes the motor to swing anticlockwise, and therefore the power wheel on the motor is separated from the rear wheel of the vehicle. Further, the elastic component is a spring. Further, a motor arm 74 is arranged at the left part of the motor, and the deflector rod drives the motor arm to enable the motor to deflect relative to the frame. Specifically, in the process of switching the baby carrier from the electric power-assisted state to the sliding-step state, the shifting lever is contacted with a motor arm of the motor, and the shifting lever pushes the motor arm to enable the motor to swing anticlockwise, so that a power wheel on the motor is separated from a rear wheel of the baby carrier. Further, the inside stopper 834 that is equipped with of through-hole of knob, the outside cover of rotation axis is equipped with spring 8211, the spring is located inside the through-hole, the one end butt of spring is in stopper, other end butt in the lateral wall of fixing base. Specifically, the spring is sleeved outside the knob shaft to achieve the effect that the knob automatically returns in the front-rear direction, and when the sliding rod is located in the center of the limiting groove, the spring pushes the knob outwards to enable the shifting rod to be located in the center of the limiting groove, so that the knob is locked. Further, the free end of the rotating shaft is provided with a limiting portion 8212 which blocks the knob from moving outwards along the rotating shaft and separating from the rotating shaft. In particular, the stopper is preferably a screw. Further, the limiting groove comprises a first limiting groove 8231 and a second limiting groove 8232, a power supply micro switch 9 is arranged at a position corresponding to the first limiting groove, and the driving lever is used for shifting the power supply micro switch when being positioned in the first limiting groove. Specifically, first spacing groove is the spacing groove of keeping away from the motor arm, and the second spacing groove is the spacing groove that is close to the motor arm, and when the driving lever was located first spacing groove, the power wheel on the motor contacted with the car rear wheel, was in electric power assisted state this moment, and near the power micro-gap switch of first spacing groove was stirred to the driving lever this moment, made the motor be in operating condition, at the switching in-process, avoided the manual motor of opening, and is simple and convenient.
