Description

Technical Field

[0001] The invention relates to the field of cover products, in particular to a cover which can be opened and closed automatically. Background Art

[0002] There are two designs of existing automatically opening and closing lids: one is to use a gravity block and a movable lid fixed as an integrated structure, and the movable lid changes a corresponding angle by tilting the container, thereby realizing automatic opening and closing of the lid. The disadvantage is that although the lid can be opened and closed automatically, the angle at which the container needs to be tilted is large, which is inconvenient to use; the other is to use a gravity block to drive the rotation of a gear set, and the rotating shaft of the gear set drives the rotation of the movable lid, thereby realizing automatic opening and closing of the lid. The disadvantage is that although the lid can be opened and closed automatically, the structure is complicated, the manufacturing cost is high, and it is not economical. Summary of the invention
