New electric stroller

Abstract

The invention discloses a new type of electric baby carriage, which includes a tire, the tire includes a carcass arranged along its outer periphery, the carcass is made of solid rubber, the carcass extends from the sidewall to the crown, and the surface of the crown is provided with bosses, bosses Ribs and ribs, the ribs are arranged at intervals along the center of the crown, there are gaps between adjacent ribs, and a middle cavity is provided under the ribs; the bosses are located on both sides of the gap between two adjacent ribs; There is a side cavity, the shape of the side cavity corresponds to the boss; the ribs and the bosses are alternately arranged at intervals, and the ribs extend from the side of the rib to the shoulder, and the side cavity and the middle cavity are filled with shear-hardened elastic foam filler. By adding bosses, ribs and ridges on the surface of the tire, the tire can run on special outdoor roads such as sand, mud or snow, and at the same time add elastic foam fillers in the carcass to reduce the vibration and rebound potential energy of the tire. Adsorption is carried out to reduce the number and height of rebound, protect the wheel hub and improve driving comfort.

Description

technical field [0001] The invention relates to a baby carriage, in particular to a novel electric baby carriage. Background technique [0002] Electric stroller, a novel children's toy, children can drive by themselves, can also interact with parents and children, driven by a motor, it is a simulated toy electric vehicle with safe operation. [0003] Because most of the existing baby carriages are driven indoors, most of the tires are similar to family car tires. This tire is suitable for hard and frictional ground. If the driving environment becomes sandy or muddy, the tires It is more prone to slipping and other phenomena, which makes it difficult for baby carriages to drive smoothly on such roads. [0004] And along with the raising of economy, at present children's and adult's outdoor amusement projects (as sandy beach, muddy ground, snowy ground) constantly increase, and existing electrically-assisted toy car is not suitable for above-mentioned multiple amusement occa...

AI Technical Summary

Problems solved by technology

[0007] 3. There are a lot of stones and other hard particles on the road surface in the field. Due to the low hardness of tire rubber, a large number of particles or sharp objects will be stuck into the tire and damage the tire.

Secondly, due to the large number of stones and the large size, the tires of the stroller will be crushed by the stones when driving, resulting in a large deformation of the tires. When passing through a road with many stones, the tires will continue to leave the ground and touch the ground, resulting in a large amount of rebound. and vibration, a large relative vibration is easily generated between the hub and the tire, resulting in deformation and damage to the hub

[0008] If you simply use harder rubber as the material of the tire, there will be a large vibration between the ground and the tire during normal driving, which will cause the whole vehicle (seat and steering wheel) to vibrate, and the driving comfort will be reduced.
