Abstract
A stroller frame structure includes a front wheel rack, a rear wheel rack, a first linkage assembly, a coupling dock, a handle tube, a release mechanism, an armrest and a second linkage assembly that are pivotally coupled with one another. The handle tube has a lower end movable to allow the second linkage assembly to drive the first linkage assembly to move downwards to form a V-shaped folding thereby to move the front wheel rack and the rear wheel rack close to each other or extend to achieve smooth folding.
