AI Technical Summary

Problems solved by technology

But it has the following disadvantages: 1) complex structure, high production cost, large steering resistance, difficult and inconvenient operation

2) The gap between the metal strip and the frame will change when turning, so it is easy to pinch children and there is a big safety hazard

3) In the steering control mechanism of this kind of baby carriage, the front handle always moves synchronously with the push handle behind the car. When the adult behind the car wants to control the direction of the car through the push handle, the child sitting in the car will hold the handle with both hands , directly affects the steering of the stroller, making it difficult for adults to operate
