Description

[Detailed Description of the Invention] <<Industrial Application Field>> This invention relates to a sunshade structure for a vehicle, and particularly to a sunshade structure for a vehicle when an air conditioner is disposed inside the vehicle.

<Conventional technology and its problems> In order to adjust the temperature, humidity, etc. inside the car, an air conditioning unit is installed in the car, and ducts are piped from the air conditioning unit to several locations inside the car, and the ducts are installed at the middle or end of the duct. Cooled air, heated air, etc. are sent into the vehicle from the attached outlet grille (air outlet).

By the way, when installing ducts to convey conditioned air from the air conditioning unit to various locations in the vehicle interior, it is necessary to Restrictions on duct placement, length, number, etc. are forced. This also applies to restrictions on the location and number of outlet grilles for sending air through the duct into the vehicle interior.

Therefore, the arrangement of outlet grilles for the air conditioned air regulated by the air conditioning unit into the vehicle interior is naturally limited to a certain number and location. For this reason, the conditioned air is blown out only to specific areas in the vehicle interior, and the air conditioned air is not blown out to other areas, so cooling and heating are concentrated only in specific areas, resulting in areas that are too cold or too warm. There was a problem that air conditioning performance was inefficient.

This problem also occurs in vehicles in which a glass sunroof or the like is attached to the roof of the vehicle, and a sunshade device is attached below the glass sunroof to adjust the amount of light transmitted from the sunroof.

This idea was created in view of these problems, and its purpose is to make it possible to blow out air-conditioned air evenly over a wide area in vehicles equipped with sunroofs and sunshade devices. Therefore, it is an object of the present invention to provide a sunshade structure for a vehicle that can improve air conditioning performance.

<Means for solving the problems> In order to achieve the above object, the present invention forms a closed space between the sunroof and the sunshade,
An air outlet of an air conditioning duct was provided in the closed space, and an air outlet for blowing the air blown into the closed space toward the inside of the vehicle was provided in the sunshade.

The air is blown out over a wide area into the interior of the vehicle through the opened air outlet grille 48.

In addition, in the above three embodiments, the effect of the present invention cannot be obtained without the sunshade installed, but if you want to use the cooling air from the air conditioning unit in hot weather, sunlight from the sunroof can also be blocked. For this reason, a sunshade is often installed, and if you want to use heating air during the cold season, the heating air is usually blown out from the bottom of the passenger compartment. A sunshade is often installed to prevent outside air from entering through the sunroof, and therefore, when cooling air or heating air is to be blown into the vehicle interior, the sunshade is often installed below the sunroof.

Furthermore, by making the sunshade made of a translucent material, cooling air, heating air, etc. can be blown out to the inside of the vehicle while sunlight is transmitted into the vehicle interior.

《Effects of the invention》 This invention forms a closed space between the sunroof and the sunshade, blows conditioned air from the air conditioning duct into this closed space, and directs the conditioned air to the inside of the car through the air outlet provided in the sunshade. Since the air conditioner blows out to the interior of the vehicle, the conditioned air can be blown out to the inside of the vehicle over a wide area, and therefore the air conditioning performance can be improved.
