Description

Technical Field

[0001] The utility model belongs to the technical field of baby strollers, and particularly relates to a front armrest structure of a baby stroller and the baby stroller. Background Art

[0002] When designing a baby stroller, in order to consider the safety of infants and young children, a front armrest device that extends forward to prevent infants and young children from falling is usually provided in front of the infant seat. In the existing design, the front armrest device is foldable and fixedly connected to the frame. When in use, it is rotated and unfolded. When the baby stroller is folded, it can also be folded with it. Moreover, when it is necessary to carry the infant in or out of the baby stroller, the front armrest device can also be folded separately; however, as the infant grows up or the front armrest device is no longer needed for older children, the front armrest device cannot be disassembled and will occupy the seat space. Each folding operation will generate additional folding action, and additional weight will be generated when carrying the baby stroller, which will cause certain inconveniences to the user and reduce the user's experience.

[0031] When designing a baby stroller, in order to consider the safety of infants and young children, a front armrest device that extends forward to prevent infants and young children from falling is usually provided in front of the infant seat. In the existing design, the front armrest device is foldable and fixedly connected to the frame. When in use, it is rotated and unfolded. When the baby stroller is folded, it can also be folded with it. Moreover, when it is necessary to carry the infant in or out of the baby stroller, the front armrest device can also be folded separately; however, as the infant grows up or the front armrest device is no longer needed for older children, the front armrest device cannot be disassembled and will occupy the seat space. Each folding operation will generate additional folding action, and additional weight will be generated when carrying the baby stroller, which will cause certain inconveniences to the user and reduce the user's experience.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the utility model provides a front armrest structure of a baby stroller, which includes: a seat bracket 10, and an armrest bracket assembly 20 installed on both sides of the front end of the seat bracket 10, and the armrest bracket assembly 20 includes: two bracket mounting seats 21, and an armrest bracket body 22 whose two ends are rotatably mounted on the corresponding bracket mounting seats 21;
