According to the present invention, a driving means for driving the rotary shaft 14 forward or reverse rotation is performed so that the lowering operation for the unfolding of the screen 16 or the lifting operation for the winding is performed.

In the configuration of the drive means, the drive gear 18 is mounted to the end of the rotary shaft 14, the rotational force transmission gear 20 is engaged with the drive gear 18, and the rotational force transmission gear 20 The motor gear 22 which provides the rotational force is engaged.

At this time, the rotational force transmission gear 20 is supported on the mounting end 24 integrally formed on the inner surface of the housing 10, the shaft of the rotational force transmission gear 20 is fastened rotatably to the mounting end (24). do.

In addition, an electric motor 26 having the motor gear 22 as an axis is mounted in the housing 10, and a control unit 28 is connected to the electric motor 26 so as to exchange electrical signals. The driving direction and the driving time of the control, and of course a switch (not shown) for the on / off of the electric motor 26 is mounted at a predetermined position adjacent to the driver's seat.

On the other hand, the screen 16 is a material that is easily shaken by the external force, it is necessary to hold the holding means to not shake when the screen 16 is lowered and unfolded.

In the holding means according to the present invention, a pair of fixed ends 30 are integrally formed at the inlet of the screen entry / exit hole 12 of the housing 10, and a pair of first ends are formed at each fixed end 30. The link 32 is hinged and a pair of second links 34 are hinged to each first link 32.

In more detail, an upper end of the first link 32 is hinged to each of the fixed ends 30, and an upper end of the second link 34 is hinged to the lower end of the first link 32. do.

In particular, the lower ends of the second links 34 are connected to each other by a weight bar 36 having a horizontal bar shape, and the lower ends of the screens 16 are fixed to the weight bars 36 to form a screen ( The screen 16 can be easily unfolded by the weight of the weight bar 36 when the 16 is lowered.

Thus, when the screen 16 is unfolded, the first and second links 32 and 34 form a vertical arrangement at both ends of the screen 16 to serve as a skeletal body to hold the shake of the screen 16. Will be

On the other hand, in the operation in which the screen 16 is lifted and wound on the rotary shaft 14, when the first and second links 32 and 34 form a perfect vertical arrangement, the first and second links 32 and 34 are used. ) May not be folded about the hinge fastening point, so that when the screen 16 is unfolded, the first and second links 32 and 34 are moved inwardly around the hinge fastening point. To an obtuse angle toward the screen).

More specifically, the first stopper 38, which is applied to the upper end of the first link 32, is integrally formed to protrude at a predetermined position of the fixed end 30, and the top of the second link 34 is formed. The second stopper 40, which is applied to the end, is integrally formed to protrude to a predetermined portion of the lower end of the first link 32, so that the first and second links 32 and 34 are inward about the hinge fastening point. Make an obtuse angle of about 170 ° towards the direction (screen side).

Therefore, in the operation in which the weight bar 36 and the screen 16 are lifted and the screen 16 is wound on the rotation shaft 14, the first and second links 32 and 34 are arranged at an obtuse angle with each other. Since the first and second links 32 and 34 are easily folded inward with respect to the hinge fastening point.

Here, the operation of the electric sun visor of the present invention having the above configuration will be described.
