Description

Automobile rear ventilation opening structure with double-layer blade structure

Technical Field

The utility model relates to a car ventilation structure field especially relates to a vent structure behind car of double-deck blade structure.

Background

The automobile ventilation opening structure mainly adjusts the air pressure inside and outside an automobile, and the air pressure inside and outside the automobile is balanced by arranging one air pressure adjusting structure at the left and right rear side walls of the automobile respectively. Without the ventilation structure adjustment (i.e. assuming that the vehicle is a completely closed compartment), a large positive pressure (Δ P) is generated when the vehicle door is opened and closed, and as can be seen from Δ F = Δ P × S (P is pressure, F is pressure, and S is unit area), a large outward thrust Δ F is generated in the vehicle, and this thrust Δ F is a significant portion of the door closing force (F), and even directly affects the magnitude of the door closing force (F). Therefore, the rear side wall ventilation opening structure needs to be designed to reduce the positive pressure (delta P), the smaller the positive pressure (delta P), the better the positive pressure (delta P), and even the best positive pressure (delta P) is to be 0, so that the effect of reducing the door closing force is achieved, and the experience of customers (car owners) is enhanced. At present, the structural arrangement form of the automobile rear side wall ventilation openings is 'bilateral symmetry arrangement', namely two automobile ventilation opening structures, namely a left ventilation part and a right ventilation part, are arranged. The area size of the automobile vent structure is designed according to the requirement of the automobile body metal plate arrangement space. However, for small or miniature vehicles such as the existing electric vehicles, the vehicle body is small, and a rear side wall vent structure with a large or proper size area cannot be arranged, so that the closing force of the door of the vehicle is large when the vehicle is closed, the door cannot be closed conveniently and laborsavingly, the vehicle experience is poor, and the overall quality and the market sales of the vehicle are influenced.

Through retrieving "CN206049298U" an automobile vent structure can effectively increase the inside air-out area of car through setting up middle ventilation structure, when needs increase the interior air-out of car, can effectively improve the interior air output of car, reduce the door by a wide margin and close the power, improve the vehicle travelling comfort, but the middle ventilation structure that this structure set up blocks the entering of dust that the design such as single blade design can not be fine for the inside dust of car air pipe can become more and more along with the lapse of time.
