The invention provides an electric bicycle automatic supporting leg device, comprising a housing, a motor, a turbine worm reduction box, a transmission screw, a screw-nut pin, a screw-nut connecting rod, a left guide bearing, a right guide bearing, a left support bearing, a right support bearing, a left rotary supporting rod, a right rotary supporting rod, a left supporting leg, and a right supporting leg. Two side surfaces of the housing are provided with a left guiding groove and a right guiding groove. A motor in the inner cavity of the housing is connected with the turbine worm reduction box and the transmission screw in sequence. The screw-nut pin is horizontally connected with the transmission screw by threads, and is longitudinally connected with the screw-nut connecting rod. Two ends of the screw-nut connecting rod are connected with the inner side ends of the left rotary supporting rod and the right rotary supporting rod. The left guide bearing and the right guide bearing are sleeved on two ends of the screw-nut connecting rod which is on the outer side of the left rotary supporting rod and the right rotary supporting rod. The left guide bearing and the right guide bearing are respectively arranged in the left guiding groove and the right guiding groove. The middle parts of the left rotary supporting rod and the right rotary supporting rod are provided with a left gain and a right gain. The housing under the left guiding groove and the right guiding groove is fixedly provided with the left support bearing and the right support bearing. The left support bearing and the right support bearing are respectively arranged in the left gain and the right gain. The left rotary supporting rod and the right rotary supporting rod are connected with the left supporting leg and the right supporting leg. Thus, the rear end portion of an electric bicycle can be lifted, and parking is completed.
