The invention provides a folding baby carriage frame which comprises a bottom frame, a front supporting rod, a sliding push rod, a rear supporting rod, a telescopic rod and a gear motor. A pair of front wheels and a pair of rear wheels are respectively arranged at the front part and the rear part of the chassis; the lower end of the front supporting rod is hinged to the front portion of the bottom frame. A long hole is formed in the lower side of the front supporting rod. A first lug plate is arranged on the lower side of the lower end of the sliding push rod, the sliding push rod slidably sleeves the inner side of the front supporting rod, and the first lug plate downwards extends out of the long hole; the lower end of the rear supporting rod is hinged to the rear portion of the bottom frame, and the upper end of the rear supporting rod is hinged to the first lug plate. The upper end of the telescopic rod is hinged to the lower side of the upper end of the front supporting rod, and the lower end of the telescopic rod is hinged to the middle of the rear supporting rod. The gear motors are fixed to the rear supporting rods respectively and drive the telescopic rods to swing relative to the rear supporting rods. The invention further provides an automatic folding and unfolding method of the folding type baby carriage frame. The automatic folding and unfolding method is implemented by adopting the folding type baby carriage frame.
