Dual-pawl buffer power-driven door closer

The utility model relates to a dual-pawl buffer power-driven door closer. The dual-pawl buffer power-driven door closer comprises a shell, a hydraulic buffer, an electric control mechanism and a pawl trigger mechanism, wherein the hydraulic buffer, the electric control mechanism and the pawl trigger mechanism are fixed to a base plate; a door closing driving arm is fixed to one end of a rotating shaft of the hydraulic buffer, a ratchet wheel is fixed to the other end of the rotating shaft of the hydraulic buffer, and a first pawl is arranged on one side of the ratchet wheel. The electric control mechanism comprises an electromagnet and a pin rod, and the pin rod and the pawl trigger mechanism are linked; a second pawl is further arranged on the other side of the ratchet wheel, and the first pawl and the second pawl are stressed by a first spring and a second spring respectively so as to keep the trend that the first pawl and the second pawl are abutted against the ratchet wheel all the time. The pawl trigger mechanism comprises a driving plate, a manual rod, a trigger rod and a large torsional spring; the large torsional spring keeps the trend that the first pawl and the second pawl are synchronously opened through the driving plate all the time; the twisting force of the large torsional spring can be overcome through the manual rod so as to enable the driving plate to retreat back and to be hung through the trigger rod, and the trigger rod and the pin rod are linked. A dual-pawl structure is adopted, the ratchet wheel with ratchets one time larger than ratchets of a traditional ratchet wheel can be used, and the door leaf opening position angle the same as that of a traditional machine can be achieved.
