Embodiment 1

[0036] Raindrop falling speed V ABetween 4.20m / s and 10.14m / s, in the following description, we take the raindrop velocity V A is 7m / s, the normal driving speed of the car is V B Between 0 and 120km / h, the speed V of the airflow ejected by the micro high-pressure air pump C It is 48m / s. The angle between the car window and the horizontal plane is represented by a, a is 50°, the angle between the air jet port and the horizontal plane is represented by β, and 50°≤β≤180°. Taking the car as the reference frame, the raindrop mainly has its own falling speed V A , Air pump jet speed V C , The moving speed V of the raindrop relative to the window. After speed synthesis, raindrops may move obliquely upwards or downwards. When the raindrop moves obliquely upward, in order to ensure that the raindrop does not fall on the window, the falling speed of the raindrop itself is V A , Air pump jet speed V C , the speed V of the combination of raindrops relative to the moving speed V of...

Embodiment 2

[0079] When the angle β between the jet port and the horizontal plane satisfies 90°≤β≤171°, Figure 7 Among them, a is the side length of the inclined plane of the car window, b is the projection of the side length of the inclined plane of the car window in the vertical direction, c is the projection of the side length of the inclined plane of the car window in the horizontal direction, and the angle a between the car window and the horizontal plane is 50° , the angle between the jet port and the horizontal plane is β, e is the moving speed of the car, f is the moving speed of raindrops relative to the car window is V, and g is the jet speed of the air pump V C , h is the vertical falling velocity V of raindrops A , the intersection pointed by k is the raindrop. In order to ensure that the raindrops do not fall on the window, the falling speed of the raindrops is V A , Air pump jet speed V C , the speed V of the combination of raindrops relative to the moving speed V of the...

Abstract

The invention discloses a self-cleaning rainproof device for an air curtain. The self-cleaning rainproof device for the air curtain comprises a puff port support installed under a car window, multiple puff ports communicated with an air pipe are formed in the puff port support, and the puff ports are connected through a rotating motor. The air pipe is connected with an air pump used for supplying air, and the air pump and the rotating motor are further connected with an electric cabin used for supplying power and controlling the work state. According to the self-cleaning rainproof device for the air curtain, the electric cabin is controlled by a user to enable the air pump to supply air to the air pipe, and the air is erupted through the puff ports below the car window, so that the rain, snow or impurities attaching on the car window are removed. The air injecting direction of the puff ports is adjusted through the rotating motor, the clearing range is large, and the purpose of high-speed self cleaning of the car window can be realized. The self-cleaning rainproof device for the air curtain has the advantages that the wind drag of windshield wiper skeleton is removed, the system structure is simple, the operation is convenient, the performance is stable, the cleaning range is large, the eyesight does not be blocked, the visibility of the car window is improved, the problem that the windshield wiper is easy to be frozen with the glass is solved, and the vehicle performance is improved greatly.

Description

technical field [0001] The invention belongs to the field of automobile equipment, and in particular relates to an air curtain self-cleaning rainproof device. Background technique [0002] With the rapid development of modern science and technology, in many fields of industrial production and social life, designers are increasingly designing products from the perspective of humanization. People not only pursue the practical value of products, but also pay more attention to its visual effects and Streamlined overall design. Aerodynamics is a key factor in improving vehicle performance, whether the discussion is about how fast a vehicle can run or how fuel-efficient it is, which is why automakers continue to spend heavily on making products more streamlined to reduce gaps, developing dynamic aerodynamic aids, and even Subtract the design. The use of air curtain self-cleaning rainproof device to replace the traditional rubber wiper just reduces the wind resistance of the rubb...
