一种三折半婴儿推车
By introducing a rotation offset mechanism and a tilting receiving groove into the tri-fold baby stroller, the problem that the rear wheel structure cannot be adjusted in space in the prior art is solved, achieving a more compact and stable folding effect, simplifying operation and avoiding interference.

AI Technical Summary
Existing tri-fold strollers are bulky and not compact when folded. The movement trajectory of the rear wheel structure is strictly limited, and the spatial position cannot be actively adjusted, making it difficult to compress the width when folded, which may cause interference with other components.
A rotary offset mechanism is used as the rotation center of the rear wheel structure. Combined with an inclined receiving groove and mechanical limit, the rear wheel structure generates linear offset during rotation. The composite motion of the rear wheel, including rotation and linear offset, is achieved through the design of the tilt angle θ, ensuring that the rear wheel can actively approach and embed itself into the vehicle body when it is retracted.
It effectively reduces the overall width after folding, avoids component interference, achieves a more compact and stable folding shape, simplifies the operation process, and improves convenience and safety.
