The invention discloses a seat plate driving mechanism of a baby carriage. The seat plate driving mechanism comprises a lead screw, a hand wheel, a first rope, a second rope, a third rope, a fourth rope; a sliding plate and a supporting frame which form a sliding pair, a seat plate and the sliding plate form a sliding pair, the hand wheel is rotated clockwise, the lead screw drives the sliding plate to move backwards through a screw hole, under the push of a second guide wheel and a third guide wheel, the upper ends of the second rope and the third rope move backwards, so that the seat plate moves backwards; the hand wheel is rotated anticlockwise, the lead screw drives the sliding plate to move forwards through the screw hole, and the upper ends of the first rope and the fourth rope moveforwards under the push of a first guide wheel and a fourth guide wheel, so that the seat plate moves forwards; a thread pair formed by the lead screw and the screw hole has a self-locking function, so that the movement of the sliding plate can only be controlled by the rotation of the hand wheel, and the movement of the seat plate can only be controlled by the movement of the sliding plate and cannot be spontaneously moved by a winding connection structure of the first rope, the second rope, the third rope and the fourth rope.

    本发明公开一种婴儿车的坐板驱动机构,包括丝杠、手轮、第一绳、第二绳、第三绳、第四绳,滑板与支撑架构成移动副,坐板与滑板构成移动副,顺时针转动手轮,丝杠通过丝孔驱动滑板向后移动,在第二导轮和第三导轮的推动下,第二绳和第三绳的上端向后移动,从而使坐板实现向后移动的动作;逆时针转动手轮,丝杠通过丝孔驱动滑板向前移动,在第一导轮和第四导轮的推动下,第一绳和第四绳的上端向前移动,从而使坐板实现向前移动的动作;丝杠与丝孔构成的螺纹副具有自锁功能,使滑板的移动只能由手轮的转动来控制,第一绳、第二绳、第三绳和第四绳的缠绕连接结构可使坐板的移动只能由滑板的移动来控制,而不能自发移动。
