Baby stroller

Abstract

The invention discloses a baby stroller which comprises a stroller frame, a seat assembly, at least one set of wheels and a seat swinging mechanism. The seat swinging mechanism comprises a crankshaftand a drive rod, wherein the two ends of the crankshaft and the set of wheels are coaxially arranged, the crankshaft is provided with a bent part, one end of the drive rod is rotationally connected with the bent part, the other end of the drive rod is rotationally connected with one side of the seat assembly, and the side opposite to the side, connected with the drive rod, of the seat assembly isrotationally connected with the stroller frame. By the adoption of the baby stroller, the crankshaft is made to selectively conduct circular motion synchronously with the rear wheels, so that the seatassembly is driven to swing up and down, the position of the seat assembly in the front and back direction is barely changed, so that it is guaranteed that a child can touch a handlebar with the hands and put the feet on pedals, and the feet cannot hang in the air. By the adoption of the baby stroller, it is kept that the functions of the baby stroller are not changed, meanwhile, the interactionfunction between the child and the baby stroller is added, the interest is enhanced, the locking relation between the crankshaft and the wheels can be relieved, and the operation process is simple andconvenient.

Description

technical field [0001] The invention relates to a stroller, in particular to a stroller with a swingable seat. Background technique [0002] The main structure of a stroller generally includes a vehicle frame, a front wheel and a rear wheel mounted on the bottom of the vehicle frame, and a vehicle seat connected to the vehicle frame. The front wheel and the rear wheel of the four-wheel baby carriage are respectively two, the front wheel of the three-wheel baby carriage is one, and the rear wheel is two. A handlebar steering assembly for steering and a pedal assembly for driving the front wheel to rotate. Whether the children's wheels in the prior art are three-wheeled or four-wheeled, they can only be ridden or driven by electricity, or carried out by adults. The function is relatively single, and the interaction between children and the car is not strong and interesting enough.

Problems solved by technology

Whether the children's wheels in the prior art are three-wheeled or four-wheeled, they can only be ridden or driven by electricity, or carried out by adults. The function is relatively single, and the interaction between children and the car is not strong enough to be interesting enough.

Invention patent CN101519080B discloses a crankshaft-type dynamic baby carriage, which drives the seat movement through the rotation of the crankshaft, but the problem is that the seat also moves forward and backward while moving up and down. Changes, that is, the distance between the child on the seat and the front of the stroller changes, and the child's hands may not be able to reach the handlebars when the seat is moved backwards, or the child's feet may not be placed on the pedals, and the child may be suspended in the air.
