Double stroller structure

This creation relates to a stroller, especially a double stroller structure that is compact in structure, structurally stable, and has both convenience and safety.

In general, families will have a baby stroller for baby travel, but when there are two babies or young children in the house, it is obviously not a convenient choice to push two baby strollers; therefore, some families will buy one directly. A double-seat stroller, at the same time, takes care of two children at the same time.

In the case of today's two-seater strollers, the position of the ride can be mainly divided into front and rear seats or left and right seats. The front and rear strollers have a long body, so that the children in the front seat are far away from the parents. It is less convenient. In addition, regardless of whether the rear seat and the front seat are installed in the same direction or in the opposite direction, the child in the back seat will be blocked by the front seat or the stroller in the field of view, so that the rear seat child can only be seated. The scenery on both sides is bound to be greatly reduced for the beauty of traveling with children.

As for the left and right strollers, because the children can ride on the left and right seats side by side, it is convenient for children to go out and watch the scenery. However, because the body of the left and right strollers is wide, the body frame is also larger. Heavy, relatively inconvenient in handling, once the child’s weight difference between the children is large, Affecting the center of gravity of the stroller, this also makes it necessary for parents to pay extra attention to the balance of the car body when pushing the stroller of the left and right seats to avoid the child injury caused by the unstable center of gravity of the stroller.
