Overturning device

Abstract

The invention relates to an overturning device comprising a first damper and a second damper. Rotating shafts, elastic pieces and meshing structures are arranged in the two dampers correspondingly, the elastic pieces are mounted on the rotating shafts in a sleeving mode, and the rotating shafts are connected with the meshing structures and overturning pieces correspondingly; the elastic pieces comprise inner compressed springs and outer compressed springs, and the length and the spring constant of the outer compressed springs and the inner compressed springs are different correspondingly; themeshing structures comprise damping moving blocks and meshing bodies, and the meshing surfaces of the damping moving blocks and the meshing bodies are bevels; and the rotating shafts drive the overturning pieces to be easily opened under the action of the elastics pieces, and the overturning pieces are safely and slowly closed under the friction force action of the elastic pieces to the rotating shafts. According to the overturning device, the structural design is reasonable, force in the left-right direction is balanced, overturning is smooth, the overturning pieces are not prone to deforming, operation is more stable, convenient, flexible with low labor consumption, closing of the overturning pieces is safer, the selected powder of a driving mechanism is smaller, the cost is lower, and the market competitiveness and brand images of enterprises are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of industrial control, in particular, the invention relates to an automatic turning device for opening and closing a turning member such as a cover or a door. Background technique [0002] Products such as household appliances, automobiles, etc. generally include flippers such as lids or doors. Some flippers are manually opened and closed, however, with the development of technology, people have higher and higher requirements for automation of these products, and it is desired that flippers such as lids or doors can be opened and closed automatically. In order to realize the automatic opening and closing function of the turning part, many manufacturers have developed the turning part with the automatic opening and closing function. However, there are still problems in the products with such flippers on the market at present, and cannot fully satisfy the needs of consumers. [0003] For example, most of the...

AI Technical Summary

Problems solved by technology

High-power motors not only produce noise when working, but also consume high energy consumption, are bulky, inconvenient to assemble, and increase the cost of the overall system

In addition, since the overturning moment of the overturning part does not change linearly, when the overturning part is driven by a motor, the overturning part cannot be overturned at a uniform speed and smoothly, and the comfort is poor

[0004] In addition, for heavy reversing parts, if the motor is directly driven, the load on the motor will be large, and the motor will be overloaded for a long time, which will easily cause damage to the motor and increase maintenance costs.

It will also cause users to complain about product quality, which will affect the company's market competitiveness and brand image

[0005] In addition, existing flippers cannot automatically stop under abnormal conditions (such as power failure, motor failure, or component failure), but close downwards under the force of gravity

The huge impact force when closing will hurt the human body and cause safety accidents

Moreover, the existing overturning member will not stop or rise in the opposite direction when it encounters a reaction force during the closing process, but will continue to fall, which will pinch the human body and cause a safety accident
