Description

Technical Field

[0001] This utility model relates to a vehicle body with a sliding rail mechanism, and more particularly to a vehicle body with a sliding rail mechanism that allows for adjustable seating or storage space. Background Technology

[0002] Strollers are one of the most famous inventions of the 20th century, and their applications are quite extensive, such as single strollers, double strollers, shopping carts, camping strollers, hand strollers, baby strollers, etc. Among them, baby strollers are undoubtedly one of the most important items in parenting life. Whether it is daily outings, shopping, or long-distance travel, a suitable baby stroller can make young children ride comfortably and make it easier for parents to travel.

[0003] However, due to their lightweight design, strollers are less comfortable for babies to ride in and have limited storage space. Traditional stroller designs prioritize portability, resulting in limited storage space. If you want to increase storage space, strollers are usually heavier and larger, making them difficult to operate in narrow spaces.

[0004] Babies of different ages require different strollers. Babies under 6 months old are suitable for reclining strollers and reversible strollers, allowing them to see their parents and increasing their sense of security. Babies over 1 year old may have difficulty sitting still, so an adjustable seat angle is most important to ensure their comfort. Utility Model Content
