AI Technical Summary

Technical Problem

In existing waterproofing solutions for vehicle-mounted Tbox housings, the waterproof rubber rings are prone to sealing failure due to misalignment or deformation caused by compression. Ultrasonic welding is costly and cannot be repaired, affecting equipment reliability and maintenance costs.

Method used

The rear shell sealing silicone, front shell sealing silicone, and battery cover sealing silicone are integrally molded with the shell and fixed with screws through interference pre-compression, forming a double locking design to achieve reliable sealing and removability.

Benefits of technology

It eliminates human assembly errors, improves sealing reliability, avoids water leakage failure caused by misalignment or compression deformation of traditional rubber rings, reduces maintenance costs, and achieves non-destructive disassembly and assembly of the housing.
