Definitions
- This invention relates to the field of industrial control and automation, and more particularly to an automatic turning device for opening and closing a flip member such as a lid or a door. Background technique
- Products such as household appliances, automobiles, and the like generally include flip members such as covers or doors. Some flips are manually opened and closed. However, with the development of technology, people are increasingly demanding automation of these products, and it is hoped that flippers such as covers or doors can be automatically opened and closed. In order to achieve the automatic opening and closing of the flipper, many manufacturers have developed flips with automatic opening and closing functions. However, products with such flips on the market are still problematic and cannot fully meet the needs of consumers.
- existing flippers are mostly driven directly by a motor. If the weight of the flipper is large, a motor with a higher power is required. High-power motors not only generate noise when working, but also consume high energy, are bulky, are inconvenient to assemble, and increase the cost of the overall system. In addition, since the turning moment of the flip member is not linearly changed, when the motor is driven to flip the flip member, the flip member cannot be swiftly flipped smoothly, and the comfort is poor.
- the existing flipper cannot be automatically stopped under abnormal conditions (such as power failure, motor failure or component failure), but closed downward by gravity.
- abnormal conditions such as power failure, motor failure or component failure
- the huge impact when closing will injure the human body and cause a safety accident.
- the existing flipper also encounters a reaction force during the closing process. It does not stop or rise in the opposite direction, but continues to fall, which can cause injury to the human body and cause a safety accident.
