Description

self balancing stroller

technical field

The utility model relates to a baby carriage, in particular to a baby carriage used for babies and having a self-balancing function.

Background technique

Existing baby carriages have many structures, but they all need to be supported by adults or closely watched. Once they are far away from adults, it may cause the baby to fall from the car or fall out of the car.

The utility model patent with the notification number CN2559528 provides an improved rear support frame for the baby carriage, which is fixed on the left and right poles of the baby carriage. The rotating shaft fixing seat and the rotating shaft block are respectively provided with opposite rotating shaft fixing pieces, which can be used for the pivot connection of the rotating shaft fixing seat and the rotating shaft block. In addition, a blind hole is provided on the rotating shaft block for the rod body to pass through. The support frame is composed of the above components with upper, lower, left and right corresponding to each other. It is connected to the corresponding rod body by a stopper, and a connecting rod is arranged between the upper and lower stoppers, so that the rear support frame can be made into a Linked action; the pivoting direction of the shaft fixing seat and the shaft block is the same as the direction in which the left and right rear poles are deployed, so when the left and right rear poles are deployed to carry the baby, the rear support frame can firmly support the baby The left and right rear struts of the car prevent the baby carriage from shaking when it is moving. In addition to being comfortable, it can also prolong the service life of the baby carriage and is practical.

The utility model patent with the notification number CN2752129 provides a buckle structure for a reversing seat bed of a stroller, which is a stroller composed of a rod body, four rollers and a pair of connecting rods. There are front legs and a rear leg, and there are handrails and pivotal protrusions on both sides of the bunk bed; the inside of the connecting rod is pivotally connected with buttons, buckle rods and an elastic moving component, and the top surface of the connecting rod is provided with a buckle track , the button is pivotally connected to the bottom of the connecting rod, the center of the buckle rod is pivotally connected to the inside of the connecting rod, a torsion spring is sleeved at the center pivot joint, and the side pushed by the button has a buckle hole on the other side of the buckle rod; According to this, the protruding rods on both sides of the bed are respectively inserted into the buckle hole of the buckle rod along the buckle track of the connecting rod, and are pushed by the pushing component to push the buckle rod and the elastic force of the torsion spring to maintain the buckle rod. Balance to position the bunk bed, press the button to push the buckle lever upward, and the other side of the buckle lever moves down, so that the convex rod of the bunk bed is no longer limited by the buckle hole, but can be locked from the buckle hole and the buckle The track breaks away to achieve the purpose of reversing the bunk bed.

Contents of the invention

The purpose of the utility model is to provide a self-balancing stroller to overcome the common problems of poor balance of the existing strollers, and the baby is easy to fall or fall out of the stroller.

The utility model is provided with a vehicle frame, a seat, a front wheel, a rear wheel and a bearing, the seat is connected with the vehicle frame or the front wheel through the bearing, the rotating shaft of the front wheel is connected with the upper part of the seat, and the radius of the front wheel is larger than that of the seat. Height, the vehicle frame is connected or fixedly connected with the front wheel, and the rear wheel is connected with the vehicle frame.

Compared with the existing stroller, because the utility model adopts the principle of self-balancing, that is, when the object rotates around an axis higher than its center of gravity, it will gradually become stable due to the effect of gravity and will not overturn. Like this when the utility model bumps into an obstacle, the baby can only rotate around the front wheel shaft on the seat without overturning (except the situation of rollover), thus improving the safety and helping the baby's safety. When the baby is in the car, even if there is no adult accompanying, the seat can still maintain an upright posture when the frame is overturned due to stumbling, so that the baby will not be injured, and the baby will not be injured due to the temporary negligence of the adult.
