Description

Technical Field

[0001] The present invention belongs to the technical field of foot pedal structures, and in particular relates to a hidden foot pedal structure for a baby carriage. Background Art

[0002] A stroller is a utility vehicle designed to facilitate outdoor activities for infants. There are various models available. Generally, strollers are used by children aged one to two years old, while toy cars with wheels are used by children over two years old. Strollers can benefit children's intellectual development and enhance their brain development. Strollers are a favorite mode of transportation for strolls and are essential for mothers taking their babies shopping. However, strollers can be categorized into various types based on the baby's growth and intended use. They are primarily rated by load capacity, with a typical test standard of nine to fifteen kilograms.

[0003] There are two types of baby strollers in the prior art. One type allows the baby to sit in the stroller. When the baby sits in the stroller for a long time, the baby is prone to falling asleep. When sleeping, the baby's body is prone to leaning forward, posing a safety hazard. The other type allows the baby to sleep in the stroller, but when the baby is awake, the baby's functionality is low. These two types of strollers reduce the practicality of the stroller.
