AI Technical Summary

Technical Problem

Existing ultrasonic radar brackets with excessive or insufficient interference fit lead to frequent false alarms, affecting the accuracy and reliability of the radar system. Furthermore, excessive interference fit may damage the probe and reduce sensitivity.

Method used

An ultrasonic radar bracket snap-fit ​​structure is designed, which combines axial and radial snap-fits and adopts a petal-shaped snap-fit ​​interface. The interference fit is strictly controlled, including an axial snap-fit ​​interference fit of 0.3-0.8mm and a radial snap-fit ​​width of 0.825mm. Cutting treatment is also performed to ensure snap-fit ​​stability and reduce false alarms.

Benefits of technology

It effectively reduces false alarms, ensures stable and accurate operation of the radar probe, avoids false alarms and probe damage caused by improper interference fit, and improves the accuracy and reliability of the system.
