Abstract:
A wheel turning mechanism and a pushchair frame, the wheel turning mechanism (100) comprising: a frame (1), a wheel assembly (2), and a linking assembly arranged inside the frame (1), the linking assembly comprising a locking mechanism and an actuating member (4) cooperating with the wheel assembly (2), the wheel assembly (2) comprising a wheel joint (21) and a wheel (22) connected to the wheel joint (21); the wheel joint (21) being rotatably connected to the lower end of the frame (1), the actuating member (4) being connected to the wheel joint (21), and the locking mechanism locking the wheel joint (21); under external force, after making the locking mechanism unlock the wheel joint (21), the linking assembly makes the actuating member (4) control the rotation of the wheel joint (21) relative to the wheel (1). After implementing unlocking by means of the locking mechanism and then implementing turning of the wheel assembly by means of the actuating member, the wheel turning mechanism can implement simultaneous folding and turning of the pushchair frame by means of the linking assembly, such that folding of the wheel assembly is more convenient and the space occupied after folding is smaller.
