Baby stroller improved structure

The invention provides an improved structure of a baby carriage, in particular, a shock absorber unit is provided, which can adjust the height of the reclining chair, and can make the reclining chair cushion the braking force and the bump of the road surface; and the movable rod of the shock absorber unit can be carried out Pivoting, by rotating the reclining chair, so that the baby can face or face the parents when lying down.

According to the baby stroller, the stroller for carrying the baby can make the baby lie or ride, and the parents can easily carry the baby out of the mover. Therefore, the baby stroller has been widely used in families with babies. And today's stroller has a folding function, so that parents can easily store the stroller on the vehicle, so that the stroller can be used when walking.

However, in the conventional stroller, the height of the reclining chair is fixed and cannot be adjusted. Therefore, when the parent with a higher height needs to hold the baby on the recliner, the bending is higher, and the waist is excessively bent. In the movement of the baby, the main support point of the body is located at the waist, so the moment of the waist is extremely large, so the strength of the support needed for the waist must be able to overcome the torque to grasp the baby smoothly, so it is easy to cause Injury to the waist of the parents; if the parents hold the baby in a kneeling position, the fulcrum is located in the knee, which still requires a lot of effort for the older parents, which will cause great physical strength for the parents. burden.

In addition, the conventional stroller travels on the bumpy road, and the baby stroller as a whole contains its reclining chair, which will be oscillated by the road surface. If the stroller is stationary, if the stroller is stationary, the baby will be inertia. The effect of the law is forward leaning; in the second case, it will cause the baby to be uncomfortable when lying down, and it is easy to cause the baby to be scared or fearful, and the baby may be injured by the shock or the forward tilt.

Moreover, in the conventional stroller, most of the reclining chairs are oriented in the direction of travel, that is, the baby is facing the road surface rather than facing the parents when lying down, so the baby is very likely to be unfamiliar with the environment because of the inability to see the parents. This will make the baby feel fearful, causing the baby to cry because of fear, and it is a hindrance to the baby's physical and mental development; although it is also known to provide a recliner facing the parents or back to the parents, but they want to adjust When the recliner is in the direction, the whole reclining chair should be detached and then turned and reassembled. If the baby is still lying in the recliner at this time, the parents need to spend a lot of effort, so the difficulty of disassembling the reclining chair will be improved, and the process is extremely It is easy to cause the baby to be injured and collide, which will cause great burden and trouble for the parents.
