Description

A waterproof drainage structure for automobile air intake system

technical field

The utility model relates to the field of auto parts, in particular to a waterproof and drainage structure for an air intake system of an automobile.

Background technique

As the main means of transportation in modern society, automobiles play an increasingly important role in people's lives. Various situations will inevitably occur during the driving of the car, such as climbing mountains and wading through water. In the process of wading a car, it is easy for the intake system of the car engine to get water. In order to deal with this situation, current cars often have corresponding drainage holes at the bottom of the intake system. However, when the car is wading in rainy days , The drain hole at the lowest point may become a water inlet hole, and the accumulated water will enter the intake system through the drain hole and then enter the engine, causing the engine to stall and reducing the service life of the engine.

In order to solve this problem, some cars have installed an inverted "T"-shaped rubber plug in the drain hole. This plug can ensure that the water outside the car body cannot enter the air intake system, and it can also ensure that the water inside the car does not enter the intake system. Drain holes drain to the outside of the body. However, the structure is relatively complicated, and a special plug needs to be provided. In addition, the structure of the drain hole of the air intake system also needs special settings, which is not conducive to installation and maintenance.

Contents of the invention

The purpose of this utility model is to solve the deficiency of the above-mentioned background technology, and to provide a waterproof and drainage structure for automobile air intake system.

The technical solution of the utility model is: a waterproof and drainage structure for the automobile air intake system, including a tubular body; The lower end of the drain hole is provided with a drain hole, which is characterized in that: the body is also connected with a waterproof membrane made of flexible plastic with a certain rigidity; one end of the waterproof membrane is fixed on the outer pipe wall of the body next to the drain hole, waterproof The membrane covers the entire drainage hole. When the weight on the upper end of the waterproof membrane exceeds the maximum pressure that the waterproof membrane can withstand, the unfixed end of the waterproof membrane deflects downward and forms a drainage gap with the outer pipe wall of the body.

Further, the waterproof membrane has a rectangular structure, one end of the waterproof membrane is pasted on the outer pipe wall of the body next to the drain hole, and the other end is a free end.

The utility model has the advantages of simple structure and low cost, which can reduce the cost by 60-70% compared with the use of rubber plugs, and is convenient for installation and maintenance, and has great popularization value.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 4, it is a reference diagram of the prior art, and the inverted "T"-shaped rubber plug 6 is used to block the drain hole. Although such an arrangement can effectively meet the requirements of drainage and waterproof, the rubber plug needs to be specially made. Moreover, the plug hole of the drain hole also needs to be provided, which is not conducive to subsequent installation and maintenance.

A waterproof and drainage structure for automobile air intake system as shown in Figures 1 to 3, including a tubular body 1, the body 1 is arranged at the lowermost end of the air intake device such as an air filter or a resonance cavity of the air intake system 5, and the body The lower end of 1 is provided with a drainage hole 2, and the body 1 is also connected with a waterproof membrane 3 made of flexible plastic with a certain rigidity. The waterproof membrane 3 is generally made of plastic, which has good flexibility and certain rigidity.

One end of the waterproof membrane 3 is fixed on the outer pipe wall of the body 1 next to the drainage hole 2, and the waterproof membrane 3 covers the entire drainage hole 2. When the weight on the upper end of the waterproof membrane 3 exceeds the maximum pressure that the waterproof membrane 3 can withstand, the waterproof membrane 3 is not fixed. One end is deflected downward and forms a drainage gap 4 with the outer pipe wall of the body 1 . The upper end of the waterproof membrane 3 is accumulated on the upper end of the waterproof membrane 3 by the water discharged from the interior of the car. When the weight bears exceeds the rigidity of the waterproof membrane 3, the waterproof membrane 3 will bend, and the discharged water will flow from the gap 4 to the outside. .

The waterproof membrane 3 has a rectangular structure, and one end of the waterproof membrane 3 is pasted on the outer pipe wall of the body 1 next to the drainage hole 2, and the other end is a free end.

When the car is wading, the main body 1 is immersed in water, and the water outside the waterproof membrane 3 will be blocked by the waterproof membrane 3 so that it cannot enter the main body 1, thereby preventing water from entering the engine, thus avoiding accidents .

The utility model has the advantages of simple structure and low cost, which can reduce the cost by 60-70% compared with the use of rubber plugs, and is convenient for installation and maintenance, and has great popularization value.
