AI Technical Summary

Technical Problem

The complex channels of existing automotive air conditioning vents result in complex airflow patterns, which can easily create turbulence, generate low-frequency wind noise, and affect the driving experience.

Method used

The design incorporates an adjustment device and a flow guide assembly. The gear transmission drives the grille assembly and the flow guide assembly to adjust synchronously. Combined with a limit rod and a compression spring, it achieves a unified airflow state, reduces noise, and adapts to the usage needs of different seasons and user groups through multi-level spacing adjustments.

Benefits of technology

It effectively reduces low-frequency wind noise caused by turbulence, improves the driving experience, ensures uniform airflow distribution, and adapts to the comfort needs of different scenarios.

Abstract

This utility model relates to the field of automotive air conditioning vent technology, and more particularly to an anti-direct-blow automotive air conditioning vent structure, including a housing, an installation groove on the inner side of the housing, and an adjustment device installed on one side of the housing. The adjustment device includes a drive shaft, one end of which passes through the housing and is fixedly connected to a drive gear. A second gear and a first gear are meshed on the outer side of the drive gear. A connecting shaft is fixedly connected to the other side of both the first gear and the second gear. A guide assembly is fixedly connected to the other end of one of the connecting shafts. The guide assembly includes a mounting shell and a placement groove for placing the air guide plate. Anti-collision pads are fixedly connected to the four corners of one side of the mounting shell. In this utility model, the adjustment device enables the synchronous adjustment and coordination of the grille assembly and the guide assembly during gear transmission. The limiting rod can simultaneously ensure a single airflow state when the grille assembly rotates, reducing noise and improving the driving experience.
