AI Technical Summary
Technical Problem
Existing sensor protection devices have poor sealing performance and cannot meet the sealing requirements of off-road vehicles under harsh conditions such as wading through water and crossing rivers.
Method used
A sensor protection device is designed, including a housing and a protective cap. The housing has a receiving cavity and a sealing groove on its end face. The protective cap has a sealing part that forms a multi-level sealing fit with the sealing groove. The combination of multiple sealing grooves and sealing parts improves the sealing performance.
Benefits of technology
It effectively prevents dust and moisture from entering, improves the sensor's sealing performance, extends its service life, and enhances its reliability in harsh environments.
