Title:
VERTICAL LIFTING COLUMN HAVING ENCOUNTERED OBSTRUCTION DETECTION FUNCTION, AND ELECTRIC LIFTING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/241178
Kind Code:
A1
Abstract:
A vertical lifting column having an encountered obstruction detection function, and an electric lifting mechanism. A sensor is convenient to mount and dismount, and an encountered obstruction can be detected within a short time, thereby increasing the encountered obstruction response speed of the vertical lifting column. The vertical lifting column having an encountered obstruction detection function comprises a screw rod (100) and an encountered obstruction detection plate (300) arranged on the screw rod (100), wherein the encountered obstruction detection plate (300) is provided with an assembly hole (310); the screw rod (100) penetrates the assembly hole (310); the encountered obstruction detection plate (300) is provided with a sensor (400) used for measuring deformation stress on the encountered obstruction detection plate (300); two sides of the sensor (400) are respectively provided with fixing portions for fixedly mounting the encountered obstruction detection plate (300); a central angle formed by connecting two ends of the sensor (400) to the circle center of the assembly hole (310) is less than 360°; and the perpendicular bisector of a center connecting line between the two fixing portions passes through the sensor (400).
