Description

VEHICLE EXHAUST VENTILATION SYSTEM.

The utility model relates to the field of transport engineering, namely to the ventilation of the passenger compartment.

In the practice of the world automotive industry, the places for the location of the air outlet openings are determined by aerodynamic test methods using the static pressure coefficient. When testing and fine-tuning the microclimate system by choosing the right one of the exhaust ventilation system options in combination with the heating system, you can achieve comfort in the passenger compartment.

A known exhaust ventilation system located in the doors, for example front-wheel drive cars VAZ. With this type of arrangement of the exhaust openings, adverse conditions for the distribution and flow of air flows in the cabin are created. So, in winter, almost all the heated air, rising from the zone of the legs up to the ceiling of the cabin, then enters the cold rear window. Here he cools down and heads down the back of the rear seat and backs of passengers to go out through the hood in the rear doors just at the level of the lumbar passengers, forming a “cold wave, which is undesirable

A known exhaust ventilation system located on the outer surface of the uprights (prototype Japanese patent No. 61193920, B60H1 / 24), including a deflector with dampers located on the outer surface of the rear struts. This arrangement leads to corrosion of the body, as a leak occurs at the junction of the deflector with the body. Also, interior air flows do not reach in full

B60 N, the rear of the passenger compartment, therefore, perspiration (defrosting) of the rear window and rear side windows

glass occurs an ingot for a long time and not over the entire surface.

The objective of this utility model is aimed at creating an effective ventilation system, which is aimed at improving the exhaust ventilation of the passenger compartment, reducing fogging of the windows, preventing dust and exhaust gases from entering the passenger compartment, and increasing comfort in the passenger compartment.

To solve this problem, a cabin ventilation system through the luggage compartment is proposed. An exhaust ventilation deflector is installed in the luggage compartment under the rear bumper, which ensures an orderly movement of air flows through the entire interior of the car and, thanks to the cover of the deflector with the rear bumper, it does not get water, snow, dirt. Due to the fact that the openings for the air outlet in the trunk are larger than on the rear pillar, the air flow resistance is less and as a result, the air flow in the cabin increases, fogging of the windows decreases, and the noise level decreases.

Comparison of the claimed technical solution with the prior art in scientific and technical and patent documentation on the priority date in the main and related sections shows that the combination of natural features of the claimed solution was not known, therefore, it meets the patentability condition “novelty.

The proposed technical solution is applicable, since can be manufactured industrially, efficiently, realistically reproducibly, therefore, meets the patentability condition “industrial applicability.

The essence of the technical solution is illustrated in the drawings. Figure 1 - General view; Figure 2 - section aa;

W) The exhaust ventilation system of the vehicle includes a deflector (1) with

shutters (2). The deflector (1) is mounted on the body (3) through the gaskets (4) in the luggage compartment of the car behind the rear bumper (5). Under the influence of gravity, the shutters close the openings in the body of the deflector (1), which impedes the penetration of cold air from outside the dust. In the mode of ventilation, heating or air conditioning, due to the fan in the cabin, positive pressure is created. At the same time, air circulates through the entire cabin and, passing through the holes (6) between the lower edge of the rear window and the rear shelf of the trunk, enters the luggage compartment of the car. Under the influence of the pressure inside the air, the flaps (2) open and the air is vented out.

Exhaust ventilation system through the trunk has several advantages - it is the ventilation of the trunk, lower noise levels, increased air flow in the cabin, reduced fogging of windows. The openings for the air outlet in the trunk are larger than those on the rear pillar, so the airflow resistance is less, which ensures better air flow when the car is moving, especially at low speeds in the urban cycle. When extracting through the trunk in the area of the outlet openings behind the sides of the rear bumper, poor suction occurs (unlike the prototype, where the outlet openings are located on the outer surface of the body), so the air flow in the passenger compartment does not depend on the speed of the car.
