Description

Baby carriage capable of realizing automatic braking of downward steep slope based on height difference of front wheels and rear wheels

Technical Field

The invention relates to the technical field of intelligent braking of vehicles, in particular to a baby carriage capable of realizing automatic braking on a steep downward slope based on the height difference of front and rear wheels.

Background

The brake, also called braking, is an operation for stopping or reducing the speed of a running locomotive, vehicle, other transportation means, machine, or the like. The braking device is a mechanical braking device which can slow down the speed of the vehicle, also known as a speed reducer.

The brake of any traditional vehicle is controlled by the driver subjectively, so that the vehicle is decelerated and braked; however, except for the baby carriage, the general baby carriage needs parents to manually push a handle to drive the baby carriage to move, so that the burden of the parents carrying the baby is reduced, when the parents push the baby to walk, the road surface cannot be smooth, the baby carriage often encounters a large-amplitude ramp or goes down stairs, when the road surface is a large steep slope, the parents need to strongly pull the baby carriage under the influence of gravity to avoid accidents, when the mother carries the baby and holds things on the hands, the large-amplitude ramp body brings great trouble to the parents, if the parents carelessly release the handle, the traditional baby carriage generally has no function of designing an automatic brake, and irreparable disasters can occur.

In order to solve the problems, the inventor provides a baby carriage capable of automatically braking a steep slope based on the height difference of front and rear wheels, the baby carriage has the advantage that the baby carriage can automatically brake and stop moving when moving on the steep slope, and the problem that the conventional baby carriage cannot automatically brake in the using process is solved, so that potential safety hazards are reduced.
