Device capable of reducing automobile door closing force and ear pressure sense and automobile

Abstract

The invention provides a device capable of reducing automobile door closing force and an ear pressure sense and an automobile. The device capable of reducing the automobile door closing force and theear pressure sense includes a door lock sensor and a controller; the door lock sensor is connected with a door lock of an automobile door to detect states of the automobile door and send state signals; and the controller is connected with a lifter of window glass of the automobile, and the controller receives the state signals to control lifting up or down of the window glass. According to the device capable of reducing the automobile door closing force and the ear pressure sense, in the process of using, when the automobile door is opened, the window glass is controlled to automatically descend for a certain distance to generate a gap, in the process of closing the automobile door, the air squeezed into a passenger cabin is discharged from a window, air is discharged in time to eliminatethe impact of air pressure resistance on the door closing force, so as to effectively reduce the door closing force and to eliminate the ear pressure sense, the rectification period of the door closing force is shortened, the design change cost is lowered, and the quality of the automobile is improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a device capable of reducing the closing force of a car door and ear pressure feeling and the automobile. Background technique [0002] The closing performance of the car door is one of the important indicators for customers to evaluate the design of the car door and the performance of the car. For manufacturers, excessive closing force is a problem often encountered in the design and manufacturing process. With the improvement of vehicle manufacturing refinement, the air tightness is more obvious. During the closing process of the car door, the air is squeezed into the Due to the limited layout space of the pressure relief valve, the gas cannot be discharged in time. Especially for small cars, the layout space of the pressure relief valve is even more limited, which increases the door closing resistance, thus making the door closing force increase, and it will also be accompanied by ...

Problems solved by technology

For manufacturers, excessive closing force is a problem often encountered in the design and manufacturing process. With the improvement of vehicle manufacturing refinement, the air tightness is more obvious. During the closing process of the car door, the air is squeezed into the Due to the limited layout space of the pressure relief valve, the gas cannot be discharged in time. Especially for small cars, the layout space of the pressure relief valve is even more limited, which increases the door closing resistance, thus making the door closing force increase, and it will also be accompanied by the phenomenon of ear pressure. Almost every model needs to rectify the parts (sealing strips, pressure relief valves, body sheet metal, limiters, etc.) Long change period and mold design change cost, sometimes there are situations where the change cannot be made in place
