Embodiment 1

[0038] Please refer to Figure 1~4 , this embodiment discloses a specific structure of a multi-dimensional force sensor 1000, including a deformation ring 0100 and a measurement ring 0200. The deformation ring 0100 is deformed under the action of the measured load, and the measurement ring 0200 senses the deformation of the deformation ring 0100 to obtain multi-dimensional The measurement value of force / torque provides a sensing method with simple structure, easy implementation, ideal mechanical performance and accurate measurement.

[0039] The deformation ring 0100 includes a ring strain beam 0110 and fixed ends (a first fixed end 0120 and a second fixed end 0130 ) located at two ends of the ring strain beam 0110 . The fixed end is used to input the measured load loaded, and the ring strain beam 0110 is used to deform under the action of the measured load, so as to realize the separation of the components of each dimension of the measured load.

[0040] Wherein, the ring st...

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a multi-dimensional force sensor. Background technique [0002] A sensor is a device or device that can sense a specified measured object and convert it into a usable signal according to a certain rule (mathematical function rule). It is usually composed of a sensitive element and a conversion element, and plays an important role in the process of industrialization. There are many types of sensors, including displacement sensors, speed sensors, acceleration sensors, force sensors, temperature sensors and other types. Among them, the force sensor is a device that converts various force and torque information into electrical signal output. [0003] A multi-dimensional force sensor is a sensor that can simultaneously detect force / torque information in multiple directions in a three-dimensional rectangular coordinate space. For example, a six-dimensional force sensor can simultaneo...
