Drainage type air inlet pipe

Abstract

The invention relates to the technical field of automobile manufacturing, specifically a drainage type air inlet pipe; the air inlet pipe is tightly closed to the lower side of an engine hood; an airinlet of the air inlet pipe is positioned at the rear side of an air inlet grille between the front end of the hood and a bumper; the air inlet pipe comprises a deformable section and a non-deformablesection; the deformable section is fixedly connected with the non-deformable section; when the deformable section is not displaced, the deformable section and the non-deformable section are co-centered; a drain valve is arranged at the lower side of the middle of the deformable section; the drain valve communicates with the air inlet pipe; a drain hole and a rack hole are formed in the bottom ofthe drain valve; a rack slides through the rack hole and is fixedly connected with the valve core of the drain valve; the bottom of the rack is connected with an opening and closing drive device, a compression spring is arranged between the valve core and the bottom end of the drain valve; the drainage type air inlet pipe provided by the invention can solve the problem that a waterproof device ofthe air inlet pipe in the prior art can change the structure in the air inlet pipe, has an obstacle to the air inlet flow, and the structure is complicated to increase the load, and is not conducive to energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a drainage type air intake pipe. Background technique [0002] With the continuous improvement of the social and economic level, the number of cars is increasing, and it is very common for cars to pass by wading roads during the summer rainstorm season. Due to the untimely drainage of the city and the deep water accumulation in the urban road section, when the car passes by, it will cause the intake pipe of the car engine to enter the water, which will cause the engine to burst and even the car to be scrapped. [0003] Existing automobile intake pipe waterproof devices generally install valves and other related components that can be opened and closed at the intake pipe, or set up devices such as water storage tanks, water discharge tanks, and water baffles. These components or devices will occupy the original air intake pipe. The space may change the structure ...
