Abstract
A stroller frame includes a front leg, a bottom tube, a rear leg, an upper support member and a lower support member. The front leg, the bottom tube, the lower support member and the upper support member are pivotally connected to each other to form a four-bar linkage structure. The rear leg is connected to an end of the bottom tube. A lock mechanism is disposed at a pivot joint between the upper support member and the lower support member. The lock mechanism is able to lock the upper support member and the lower support member at an expanded angle, such that the front leg is able to be expanded with respect to the bottom tube. The lock mechanism is unlocked to release the upper support member and the lower support member, such that the front leg is able to be folded with respect to the bottom tube.
