Side air grille of automobile and automobile

Abstract

The invention provides a side air grille of automobile and an automobile, the air grille includes an air grille body, ventilation blades, an in-vehicle baroceptor, an external baroceptor, a controlling unit and an auxiliary fan. The ventilation blades are rotatablely installed on the air grille body, the auxiliary fan is installed on the air grille body. Signal output ends of the in-vehicle baroceptor and the external baroceptor are respectively connected with a signal input end of the controlling unit. The signal output end of the controlling unit is connected with a signal input end of the auxiliary fan. When the air pressure detected by the in-vehicle baroceptor in the automobile is greater than the air pressure detected by the external baroceptor, the controlling unit output the controlling signal to the auxiliary fan and rotates the auxiliary fan, in order to adjust the ventilation volume of the side air grille. The side air grille is characterized by simple structure and practicability, therefore platform and universalization are easily achieved, and the vehicle performance is also improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile side ventilation grille and an automobile using the ventilation grille. Background technique [0002] The side ventilation grille has become an essential part of the car. When the door is closed, it discharges the gas in the passenger compartment, reduces the air pressure in the passenger compartment, and facilitates door closing; when the air conditioner is working, discharges the gas in the passenger compartment, which is conducive to maintaining the air pressure inside and outside the passenger compartment. dynamic balance. [0003] The ventilation volume of the side ventilation grille is a key parameter to reflect its function, and its size is related to the design requirements such as the air output volume of the air conditioner, the door closing force, and the door closing time. Due to the limitation of cost, cycle and other factors, in the actual design ...

AI Technical Summary

Problems solved by technology

On the review prototypes, most of the doors have problems such as high closing force and incomplete closing, and the causes of such problems are often closely related to the ventilation volume of the side ventilation grilles

[0004] The ideal solution to such problems is to evaluate and adjust the ventilation volume of the side ventilation grilles to solve the problem at source, but this often comes with a substantial increase in cost
