Description

Hidden sunshade curtain device for vehicle

Technical Field

The invention relates to the field of automobile sun shades, in particular to a hidden sun shade device for an automobile.

Background

In the prior art, the sun-shading measures of the automobile mainly comprise three modes, namely, the original factory of the automobile is provided with glass with dark color and capable of isolating partial ultraviolet rays, the user pastes a solar film by himself, and the door of the automobile is provided with a sun-shading curtain mechanism. The mode of arranging dark glass or pasting a solar film has the following defects: 1. the ultraviolet radiation can be weakened to a certain extent, the effect is not ideal, and the driving safety is affected by poor driving sight at night; 2. When the sun is not needed and the light is needed to be fully transmitted due to weather, the solar energy collector cannot be randomly collected.

And the adoption of the car door with a sun-shading curtain mechanism can effectively avoid the problems existing in the mode of arranging dark glass or pasting a solar film. However, the implementation modes of the sun-shading curtain are generally two, one is that a guide rail is arranged on an automobile window frame, curtain cloth is slidably arranged on the guide rail, and the sun-shading is performed by sliding the curtain cloth; the other type is that a reel seat is arranged on a side frame of the car window, an inner cavity is arranged in the reel seat, a reel is arranged in the inner cavity, the reel comprises a rotating shaft and sunshade cloth wound on the rotating shaft, the sunshade cloth is unfolded by rotating the rotating shaft, and a hook on the sunshade cloth is hooked on a blocking rod arranged on the side frame on the other side to shade the sun.

The existing vehicle door with a sunshade curtain mechanism mainly has the following technical problems:

1) the curtain cloth is exposed when not used and easily dirtied, so that the attractiveness of the interior of the vehicle is affected, and the curtain cloth needs to be detached for cleaning, so that the operation is inconvenient;

2) the curtain cloth is easy to loosen and deform, so that displacement light leakage is caused, and driving safety is influenced.

The side frame of the existing car window is provided with a sunshade curtain mechanism, which mainly has the following technical problems:

1) a roller seat and a stop lever are required to be arranged on two side frames of the car window, so that the transmittance of the car window and the ventilation area when the car window needs to be opened are influenced when the sun-shading curtain is not unfolded;
