Description

A method and device for preventing rain and snow on automobile window with air curtain

technical field

The invention relates to the technical field of auto parts, in particular to an air curtain anti-rain and snow method and device for automobile windows.

Background technique

With the popularity of cars, especially the increase in the number of family cars, the market demand for car functions is more detailed and diversified. But at present, do not see the automobile device that can prevent rain and snow from entering the vehicle body when the window is opened on the market. Common car window rain eyebrow is because its area is less, and rain and snow prevention effect is limited, and rain eyebrow is installed outside the car body and can affect the original outward appearance of automobile. Under such market background, people who use cars in rainy and snowy weather have to choose to close the windows to protect the facilities in the car from rain and snow, which greatly limits the comfort and safety of the use of cars in rainy and snowy weather.

A utility model patent disclosed in the Chinese patent application publication number: 201520172325.8 discloses an insect-proof and rain-proof device for a car sunroof. The device is in the shape of an inverted low triangular prism, above which is a transparent rainproof cloth, and the two sides are supported by mesh cloth. The device can not only protect the top from rain, but also realize ventilation and insect protection on the side. But this device has only done anti-rain and snow design to automobile sunroof, then can't provide feasible anti-rain and snow design to more commonly used automobile side window.

Contents of the invention

In view of the above problems, the present invention provides a method and device for preventing rain and snow on automobile windows with an air curtain. The method can realize the function of blocking rain and snow from entering the vehicle body when the vehicle window is opened. The invention also provides a device for realizing the method. The device has the advantages of simple layout, convenient operation, and does not affect the appearance of the car. A method and device for preventing rain and snow on car windows of an air curtain, comprising a blower, an airflow conduit with a valve, a controllable throttling valve, an airflow conduit with spray holes, and an in-vehicle control system.

Preferably, the air blower can be installed separately, or can be replaced by the original fan of the automobile.

Preferably, the blower is directly connected to two airflow conduits with valves.

Preferably, the airflow conduit with a valve can control the flow of airflow to both sides or a single side of the airflow conduit with nozzle holes by opening and closing the valve.

Preferably, the airflow conduits with valves are respectively connected to the airflow conduits with spray holes on both sides of the vehicle at the bottom of the a-pillar.

Preferably, the controllable throttling valve can block the delivery of airflow in the airflow conduit by opening and closing.

Preferably, the airflow ducts with spray holes on both sides are arranged along the a-pillars on both sides, the side edges of the roof, and the c-pillars.

Preferably, the airflow conduit with spray holes on both sides is closed after passing through the c-pillar. That is, the air passages on both sides are not connected.

Preferably, the in-vehicle control system is a button type or a touch screen type.

Preferably, the in-vehicle control system can be installed on the operation panel of the center console, the screen of the center console or any other convenient location for the occupants to operate.

Preferably, the in-vehicle control system can control the switch state and wind force of the blower, the opening and closing of the valve of the airflow duct with valve, and the opening and closing of the controllable throttle valve.

detailed description

The present invention will be further illustrated below in conjunction with the accompanying drawings. The following examples are only used to understand the method and core idea of the present invention, and do not limit the implementation method of the present invention. Under the premise of not departing from the concept of the present invention, any possible changes or substitutions belong to the protection scope of the present invention.

With reference to Fig. 1 and Fig. 2, embodiment 1: a method and device for preventing rain and snow of an air curtain automobile window, including a blower 1, an airflow conduit 2 with a valve, a controllable throttle valve 3, and an airflow conduit 4 with a spray hole , In-vehicle control system 5.

Turn on the blower 1 through the in-vehicle control system 5 and open the valves of the valved airflow conduit 2 and the valves of the controllable throttle valve 3. The air flow is from the blower 1 installed in the front engine compartment along the two valved airflow conduits 2 is transported to the gas flow conduit with nozzle 4 and connected. Because the tail end of the airflow conduit 4 is sealed, when the airflow continuously flows into the airflow conduit 4 with nozzle holes on both sides, the air pressure inside the conduit increases and maintains a certain high pressure, so the airflow is ejected through the airflow nozzle holes on the airflow conduit 4 with nozzle holes, An air curtain covering the upper edge of the front and rear windows on both sides is formed. Because rain and snow generally enter the car body from the top of the window, the air curtain can block rain and snow from entering the car window.

With reference to Fig. 1 and Fig. 2, embodiment 2: a method and device for preventing rain and snow of an air curtain automobile window, including a blower 1, an airflow conduit 2 with a valve, a controllable throttle valve 3, and an airflow conduit 4 with a spray hole , In-vehicle control system 5.

The blower 1 is turned on through the in-vehicle control system 5 and the valve of the airflow conduit 2 with valves is opened, the valves of the controllable throttle valve 3 are all closed, and the air flow is from the blower 1 installed in the front engine compartment along the two airflow conduits with valves. 2 to the gas flow duct 4 with spray holes. Because the valves of the controllable throttle valve 3 on both sides are all closed, the air-flow cannot reach the rear windows on both sides. Thus, the continuously inflowing air-flow is sprayed out from the front half spray holes of the airflow duct 4 with spray holes, forming an air curtain covering the upper edge of the front windows on both sides, preventing rain and snow from entering the front windows.

With reference to Fig. 1 and Fig. 2, embodiment 3: a method and device for preventing rain and snow of an air curtain automobile window, including a blower 1, an airflow conduit 2 with a valve, a controllable throttle valve 3, and an airflow conduit 4 with a spray hole , In-vehicle control system 5.

Turn on the blower 1 through the in-vehicle control system 5 and open the valve of the airflow conduit 2 with valve on the driver side, close the valve of the airflow conduit 2 with valve on the copilot side, and close all the valves of the controllable throttle valve 3, The air flow is delivered from the blower 1 installed in the front engine compartment along the air flow duct 2 with valve on the driver's side to the air flow duct 4 with nozzles. Because the valves of the controllable throttle valve 3 on both sides are all closed, the air flow cannot reach the rear window. Thus, the continuously inflowing air-flow is sprayed from the front half spray hole of the airflow conduit 4 with spray holes on the driver's side, forming an air curtain that only covers the upper edge of the driver's side window, preventing rain and snow from entering the front window.
