A new car front and side window rainshield with enhanced ventilation and comfort

Abstract

The invention discloses a novel saloon car front side window rain shelter for restraining wind vibration noise and strengthening ventilation comfort. The novel saloon car front side window rain shelter is made of transparent resin materials, installed on the upper edge of an upper frame of a saloon car front side window, the length of the saloon car front side window rain shelter is smaller than the length of the upper frame of the saloon car front side window, small coarse sawteeth are arranged on the lower edge of the saloon car front side window rain shelter and used for disturbing airflow passing through the saloon car front side window rain shelter, airflow energy is consumed, and the wind vibration noise is further reduced. The length of the novel saloon car front side window rain shelter is smaller than that of an existing rain shelter, so that the wind area is reduced, and the aerodynamic resistance is reduced. The size of the back edge of the saloon car front side window rain shelter in the vertical direction is increased, the wind area cannot be increased, and the airflow bypasses the head positions of a driver and passages, so that discomfort caused by the fact that the high-speed airflow directly blows the heads of the human bodies is reduced, the internal ventilation requirements of a saloon car are met, the comfort of the faces of the human bodies when ventilation is carried out after the saloon car front side window is opened is improved, and the effect of reducing the wind vibration noise is achieved.

Description

technical field [0001] The invention relates to the technical field of car body design, in particular to a car front side window rain shield with low resistance, low noise and enhanced ventilation and comfort. Background technique [0002] In recent years, thanks to the rapid development of expressway construction in my country and the continuous improvement of road conditions, the effective speed of automobiles has continued to increase. Due to the needs of ventilation and demisting in the car, it is customary to open the windows when driving. However, when driving on a sunny day, with the windows open, the high-speed airflow not only blows and messes up the occupant's hair, but also affects the ventilation comfort of the human face. At the same time, the opened window glass is a flake-shaped edge protrusion, and the high-speed airflow interacts with the glass to generate high-intensity, low-frequency wind vibration noise, which will cause relatively strong discomfort to t...

AI Technical Summary

Problems solved by technology

[0006] Through literature comparison, none of the existing rainshield patents involves the reduction of aerodynamic resistance after the window is opened, the increase of ventilation, the comfort of the human face, and the reduction of the wind-induced noise of the airflow, especially the problem of solving the problem after the front and side windows of the car are opened.
