技術摘要: |
一種具安全防護之無感測器可適變剛性致動器,包括:一驅動元件、嚙合於驅動元件的至少一傳動元件、嚙合於傳動元件的一作動元件、連接於傳動元件的一撓性裝置以及連接於作動元件的一作動裝置,該作動裝置正常運作時,撓性裝置為固定狀態,該作動裝置受到衝擊時,撓性裝置使傳動元件與驅動元件或作動元件分離。藉此,可避免使用者受到作動裝置能量輸出造成傷害,進而令使用者可更安全的與作動裝置互動。
One aspect of the instant disclosure is to provide a sensorless adaptive safety actuator. The safety actuator comprises a driving unit, a transmission unit coupled to the driving unit, and an output unit coupled to the transmission unit. The transmission unit comprises a load-adaptable retracting mechanism. When the output unit experiences a mechanical load exceeding a critical value, the load-adaptable retracting mechanism causes the transmission unit to decouple from the driving unit. Thus, responding to an accident where the impact on the output unit causes a force/torque overload, the instant safety actuator is capable of effectively stopping the force/torque transmission to the work output device without the use of active sensors.
