AI Technical Summary
The existing cantilever beam sensor, which can be used for both tension and compression, is prone to lateral movement of the connecting parts under vibration and impact conditions, which can lead to increased measurement errors and wear of the bearing holes.
The system employs an elastic anti-detachment component, including an elastic anti-detachment part and a convex plate. Through the precise cooperation of the T-shaped positioning slider and the slide groove, as well as the magnetic attraction structure, multiple radial limits are formed to ensure that the radial displacement of the connector is limited under vibration and impact conditions, and the force transmission path is along the force-sensitive axis.
It effectively avoids measurement errors caused by force transmission path deviation, ensures that the sensor output signal truly reflects the actual load, and significantly improves measurement accuracy.
