As fig. 1 does the utility model discloses a structural schematic diagram of dual-purpose bassinet switching module of electric power-assisted and smooth step, including frame 1, motor 2, elastomeric element 3 and stop gear 4, the right part and the frame of motor constitute to rotate and are connected, elastomeric element's upper end and frame fixed connection, lower extreme and motor fixed connection, stop gear stirs the motor and makes the relative frame beat of motor, elastomeric element is the spring, install drive car rear wheel pivoted power wheel 22 on the motor. Specifically, the right edge of the motor is rotationally connected with the frame, the limiting mechanism stirs the motor to enable the motor to swing anticlockwise relative to the frame, at the moment, a power wheel on the motor is separated from a rear wheel of the baby carriage, and the baby carriage is in a sliding state; when the electric power-assisted state is required to be adjusted, the limiting mechanism returns to the original state, the motor swings clockwise under the upward pulling of the elastic component, so that the power wheel on the motor is contacted with the rear wheel of the vehicle, and the power is transmitted to the rear wheel of the vehicle. Further, as shown in fig. 2, fig. 3 and fig. 4, which are a schematic structural diagram of the limiting mechanism of the present invention, a schematic structural diagram of a cross section a-a in fig. 2 and a schematic structural diagram of the fixing base, respectively, the limiting mechanism includes a fixing base 41 and a knob 42, a rotating shaft 411 is vertically disposed at an outer side of the fixing base, a through hole 421 is disposed at 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 422 is disposed at an edge of the knob and extends towards the fixing base, a shift lever 423 is disposed at a free end of the sliding rod along a length direction of the sliding rod, a diameter of the sliding rod is smaller than a diameter of the shift lever, an arc chute 412 adapted to the sliding rod is disposed on the fixing base, a limiting groove 413 adapted to the shift lever is disposed at each of two ends of the arc chute, the sliding rod is inserted into the sliding groove and then forms sliding fit with the sliding groove, and the deflector rod toggles the motor to enable the motor to deflect relative to the frame. Specifically, a rotating shaft is inserted in the center of the knob, and the knob can rotate around the rotating shaft and can slide back and forth in the length direction of the rotating shaft. 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 inside stopper 424 that is equipped with of through-hole of knob, the outside cover of rotation axis is equipped with spring 4111, the spring is located inside the through-hole, the one end butt of spring is in stopping the 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 4112, and the limiting portion blocks the knob from moving outwards along the rotating shaft and separating from the rotating shaft. In particular, the stopper is preferably a screw. Furthermore, a motor arm 21 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 limiting groove comprises a first limiting groove 4131 and a second limiting groove 4132, a power supply micro switch 5 is arranged at a position corresponding to the first limiting groove, and the driving lever drives the power supply micro switch when being located 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.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the preferred embodiments, it is not limited to the present invention, and any skilled person in the art can make some modifications or equivalent changes without departing from the technical scope of the present invention.
