Baby carriage capable of automatically braking on abrupt downslope based on height difference of front and rear wheels

Abstract

The invention relates to the technical field of vehicle intelligent braking, and discloses a baby carriage capable of automatically braking on a abrupt downslope based on the height difference of front and rear wheels. The baby carriage comprises front wheels and rear wheels, the outer side of each front wheel is movably connected with a driving spring, the outer side of each movable rotating shaft is movably connected with an abutting spring, the ends, away from the movable rotating shafts, of the abutting springs are movably connected with bending rods, rod body axes are arranged in the bending rods, clamping blocks are clamped on the outer sides of the rod body axes, mounting springs are movably connected to the outer sides of the rod body axes, bearing rods are movably connected to theends, away from the front wheels, of the bearings, and bushings are movably connected to the ends, away from the bearings, of the bearing rods. According to the baby carriage capable of automaticallybraking on the abrupt downslope based on the height difference between the front wheels and the rear wheels, under the action of gravity, the bending rods are bent with the rod body axles in the bending rods as the supporting points, and meanwhile the bearing rods are bent with the bushes in the bearing rods as the supporting points; and then a brake block is firstly contacted with the ground, sothat the baby carriage is braked.

Description

Technical field [0001] The invention relates to the technical field of vehicle intelligent braking, in particular to a stroller that realizes automatic braking on steep slopes based on the height difference between front and rear wheels. Background technique [0002] Braking, also known as braking, refers to the action of stopping or reducing the speed of running locomotives, vehicles, other means of transportation or machinery. The brake device is also a mechanical brake device that can slow down the vehicle speed, also known as a reducer. [0003] Traditionally, the brakes of any vehicle are subjectively controlled by the driver to realize the deceleration and braking of the vehicle; however, the only exception is baby strollers. In general, the parents need to manually push the handles to drive the stroller. Moving reduces the burden on parents when they take their children. When parents push their children for a walk, the road surface cannot be smooth, and they often encounter...

AI Technical Summary

Problems solved by technology

[0003] Traditionally, the brakes of any vehicle are subjectively controlled by the driver to achieve deceleration and braking of the vehicle; however, only baby carriages are an exception. General baby carriages require parents to manually push the handle to drive the baby carriage. Move, which reduces the burden on parents when they take their children. When parents push their children for a walk, the road surface cannot be flat, and they often encounter large ramps or stairs. On roads with steeper slopes, Under the influence of gravity, parents need to drag the stroller hard to avoid accidents. When the mother is alone with the child and still carrying things in her hands, this large slope will bring great benefits to the parents. If the parents accidentally let go of the handle, the traditional baby stroller is generally not designed with an automatic braking function, and an irreparable disaster will occur

[0004] In order to solve the above problems, the inventor proposed a baby carriage that automatically brakes down a steep slope based on the height difference between the front and rear wheels. The function that cannot automatically brake in the middle of the car, thereby reducing potential safety hazards
