Abstract

The invention provides a rigid-flexible mixed three-dimensional force perception mechanism. The mechanism mainly comprises an upper platform, a lower platform and three deformable force measuring branches connecting the upper and lower platforms. Three edge support columns with the same height which are distributed in an equilateral triangle manner are arranged on the lower platform. A center support column is arranged in the center of the platform. Three pairs of parallel guide rails are arranged between the three edge support columns and the center support column and are connected to each other through the deformable force measuring branches respectively. Each force measuring branch consists of a sensor assembly, a first moving pair, a first revolute pair, a second revolute pair and a first universal joint. A sensor assembly is arranged between two parallel guide rails and mainly comprises a sensor, a sensor connection piece, a sensor fixing connection frame, a sensor fixing support frame, a guide rail connection frame and a spring. According to the invention, deformation can be generated in a three-dimensional force perception measurement process; space three-dimensional force information in a dynamic deformation condition is easily perceived and measured in the deformation process; and the mechanism is advantageous in that the mechanism is simple and symmetrical in structure, and easy to manufacture and serially produce.

Description

technical field [0001] The invention belongs to the field of sensors, and relates to a space three-dimensional force sensor device, in particular to a three-dimensional force sensing mechanism with both rigidity and flexibility. Background technique [0002] The three-dimensional force sensor can be used to monitor the static and dynamic forces in three mutually perpendicular directions in a space where the direction and size are constantly changing. It is widely used in industrial production, rehabilitation medicine, aerospace and other fields. In recent years, research in this field has achieved some results, such as parallel decoupling structure three-dimensional force sensor, three-dimensional force measurement device and so on.
