Now, the working process of the steering power-assisted baby stroller is specifically explained:
when the motor is in an electrified rotating state and the overrunning clutch 9 is in a closed working state, the motor output rotating shaft 80 drives the clutch input rotating shaft 10 to rotate, so that the first gear 18 drives the second gear 20 to rotate, the connecting piece 21 drives the left output rotating shaft 22 and the right output rotating shaft 23 to respectively rotate, the left rear wheel 5 and the right rear wheel 6 are rotated, and the power assisting function is realized through the motor 8;

When the motor is in a power-off and rotation-stopping state, the human-trolley can not be subjected to the resistance of the motor 8 because the overrunning clutch 9 is in a work-off state.
No matter the overrunning clutch 9 is in the on-state or off-state, if the cart runs leftwards, the front wheels 3 turn leftwards, the rotating speed of the right rear wheel shaft 60 is higher than that of the left rear wheel shaft 50, so that the rotating speeds of the right output rotating shaft 23 and the left output rotating shaft 22 are different, under the cooperation of the first bevel gear 24, the second bevel gear 25, the third bevel gear 26 and the fourth bevel gear 27, the first bevel gear 24 rotates around the axial line of the first rotating shaft 240 in a first direction, and the second bevel gear 25 rotates around the axial line of the second rotating shaft 250 in a second direction opposite to the first direction, so that the left rear wheel 5 and the right rear wheel 6 do not rotate at the same speed to smoothly turn the cart, and the cart runs rightwards and runs leftwards similarly, and is not repeated; if the cart is in straight line, the rotating speeds of the left rear wheel 5 and the right rear wheel 6 are the same, the first bevel gear 24 and the second bevel gear 25 do not move relatively, and the first bevel gear and the second bevel gear rotate together with the connecting piece 21 around the axis line extending along the left-right direction, so that the cart is in straight line. In other embodiments, only one of the first and second bevel gears 24, 25 may be provided.
The sequence of the embodiments of the present invention is only for description, and does not represent the advantages and disadvantages of the embodiments.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
