Abstract

본 발명은 대형 버스 엔진실의 리어 플랩 도어의 구조를 개선하여 엔진실에서 발생한 소음의 외부 유출에 대한 차음성을 저하시키지 않으면서 엔진실 내부의 가열 공기에 대한 배출성을 향상시킬 수 있도록 하므로써 엔진의 냉각성능 및 차량의 외관미를 동시에 향상시킬 수 있도록 한 것이다.The present invention improves the structure of the rear flap door of a large bus engine compartment so as to improve the exhaustability of the heated air inside the engine compartment without degrading the sound insulation against external leakage of noise generated in the engine compartment. It is to improve the cooling performance and the appearance of the vehicle at the same time.

본 발명은 상부수직면(4a)에서 연장형성된 절곡경사면(4b)과 상기 절곡경사면(4b)에서 연장형성된 하부수직면(4c)을 가지는 상부플랩(4)과, 상기 상부플랩(4)의 하부수직면(4c)과 일정간격 이격되며 지지브라켓(6)으로 연결되는 하부플랩(7) 사이에 엔진실(2) 내의 가열공기를 배출시키기 위한 공기 유동로(5)가 형성되는 대형 버스용 엔진실(2)의 리어 플랩 도어 구조이다.The present invention has an upper flap (4) having a bent slope (4b) extending from the upper vertical surface (4a) and a lower vertical surface (4c) extending from the bending slope (4b), and a lower vertical surface of the upper flap (4) The engine compartment for a large bus (2) in which an air flow path (5) for discharging heating air in the engine compartment (2) is formed between 4c) and a lower flap (7) spaced at regular intervals and connected to the support bracket (6). ) Rear flap door structure.
