Title:
SENSOR ASSEMBLY, FORCE DETECTION DEVICE AND METHOD, AND CONSTRUCTION MACHINERY
Document Type and Number:
WIPO Patent Application WO/2021/128798
Kind Code:
A1
Abstract:
A sensor assembly, a force detection device and method, and construction machinery, the sensor assembly comprising a connecting part (100) used for connecting a base to be tested and a bearing part (200) used for bearing, the bearing part (200) being connected to the connecting part (100), the bearing part (200) comprising at least two sensing units (210, 220) with different measuring ranges, and the at least two sensing units (210, 220) being arranged to have a different initial gap (b1, b2) from the connecting part (100), so that the bearing part (200) eliminates the corresponding initial gap (b1, b2) when the applied load reaches different extents. The different initial gaps (b1, b2) are eliminated by means of the applied load reaching a different extent, so that the sensing units (210, 220) with different measuring ranges can provide detection feedback in the respective working conditions in which the units have the highest measurement precision, ensuring the accuracy of detection results.
