Title:
MECHANICAL POSITION-LIMITING DEVICE, AND MECHANICAL POSITION-LIMITING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/206766
Kind Code:
A1
Abstract:
A mechanical position-limiting device, and mechanical position-limiting method. By providing a slip mechanism (40) having slipping direction controllability between an input shaft (10) and a transmission mechanism (30), providing an additional trigger mechanism (50) to trigger the slip mechanism (40) to slip toward different directions, and linking motion of the trigger mechanism (50) and an output shaft (20), the trigger mechanism (50) triggers, after the output shaft (20) outputs a predetermined quantity, the slip mechanism (40), such that the input shaft (10) slips with respect to the transmission mechanism (30), and the output shaft (20) stops rotation. The mechanical position-limiting device of the present invention has a purely mechanical design requiring no electronic elements such as sensors, and thus requires no power supply. In addition, by having a linked arrangement of the trigger mechanism and the output shaft, the present invention effectively utilizes self-rotation of the output shaft to drive the trigger mechanism to trigger the slip mechanism, thus realizing a position-limiting function; during the slipping, the output shaft stops rotating even if the input shaft continues to provide input in the same rotating direction, thus achieving a fuzzy input and a constant output.
