The invention provides a frame folding mechanism (101), a frame locking mechanism (102), a backrest unlocking mechanism (103) and a stroller (100). A handle (11), a front foot (12), a seat portion (2) and a linking member (3) of the frame folding mechanism (101) form a planar linkage mechanism. The handle (11) and the front foot (12) can be driven to rotate and fold toward a rear foot (13), so as to drive the seat portion (2) to rotate and fold. The frame locking mechanism (102) can drive a sliding member (6) and a frame expansion locking member (7) to slide by an unlock driving mechanism (8), such that the frame expansion locking member (7) disengages from a handle locking hole (114) and a front foot locking hole (123) to unlock a frame (1). The backrest unlocking mechanism (103) has a backrest locking member (9). The unlock driving mechanism (8) can drive the backrest locking member (9) to slide, such that the backrest locking member (9) disengages from a backrest portion (4) to unlock the backrest portion (4).
