[0002] At present, buffer automatic door closers are widely used in people's daily life, and buffer automatic door closers are usually used for doors in house construction. With the continuous development of home appliance related technologies, some high-end home appliances It is also equipped with a buffer automatic door closer. Taking refrigeration equipment (refrigerators, freezers or wine cabinets) as an example, the door is installed on the cabinet through hinges, and a buffer automatic door closer is set between the cabinet and the door. The hinge is equipped with a return spring to realize the function of closing the door automatically, and the buffer automatic door closer is usually equipped with a damper to realize the function of buffering, and the damper used generally adopts the method of friction or spring, which is in actual use. There are the following problems: when the user closes the door with insufficient force, the return spring cannot completely overcome the resistance of the damper, and the door body cannot be completely closed; when the user closes the door with too much force, the movement speed of the door body is too large, and the damper The cushioning effect is weakened, and under the action of the return spring, it will have a greater impact on the cabinet
