Abstract

본 발명은 차량의 이상상태 발생시 해당부품의 이상상태를 외부에 알리는 경고램프의 점등과 동시에 경고음을 발생시키는 경고부저의 구성을 간소화하며 신속하고 정확한 경고음을 발생시킬 수 있는 경고부저 어셈블리에 관한 것으로, 차량의 각 부위에 장착되는 전장품에 이상상태가 발생하였을 때 동작하는 경고램프의 동작상태에 따라 연동하여 경고신호를 외부에 발생시키는 경고부저를 일체형으로 구성시켜 정확한 경고신호를 발생시키도록 하고 경고부저의 구조를 일체화시키므로써 조립공정이 단순화되며 공정단가가 작아지는 효과가 있다.The present invention relates to a warning buzzer assembly capable of generating a quick and accurate warning sound while simplifying the configuration of a warning buzzer that generates a warning sound at the same time a warning lamp lights up to inform the outside of an abnormal condition of a corresponding part when a vehicle abnormal condition occurs. The warning buzzer generates an accurate warning signal by integrally constructing a warning buzzer that generates a warning signal externally by interlocking according to the operation status of the warning lamp that operates when an abnormal condition occurs in the electrical equipment mounted to each part of the vehicle. By integrating the structure of the assembly process is simplified and the process cost is reduced.
