LINEAR ACTUATOR WITH FORCE SENSING MECHANISM

Abstract

A linear actuator with a force sensing mechanism comprises: a housing body (10) with a mounting component (11); a transmission mechanism (20) connected to the housing body (10) and comprising a constraint component (21); an elastic body (30) arranged between the mounting component (11) and the constraint component (21); and a Hall sensor set (40) arranged between the mounting component (11) and the constraint component (21); wherein, when a force applied to the transmission mechanism (20) is changed, a relative displacement is generated between the constraint component (21) and the mounting component (11), and thus an output signal is generated by the Hall sensor set (40) due to the displacement.Accordingly, benefits are provided such as preventing equipment damage due to impacts and detecting whether a patient is in a bedridden or unconscious state at a desired time.
