Referring to Figure 4 describes the operation of the sunglasses sun visor 12 control device of the vehicle in more detail as follows.

First, SW1, SW2, SW3, SW4, SW5, SW6, SW7, and SW8 are switches for rotating the sunglasses sun visor 12 up and down by driving the first motor 14. In addition, SW3 and SW4 are limit switches for stopping the driving of the first motor 14 when the sunglasses sun visor 12 is positioned at a predetermined point while the first motor 14 is driven. The limit switch may be installed at one end of the first rod 22 and the second rod 26 or may be installed at the outer surfaces of the first and second housings 32. SW5 and SW6 are switches for supplying a power supply voltage of the vehicle such that the first motor 14 rotates forward or reversely in association with the operations of R1 and R2. SW7 and SW8 are switches for supplying a power supply voltage of the vehicle such that the second motor 36 rotates forward or reversely in conjunction with the operations of R3 and R4. Here, reference numerals a, d, g, and j are anode terminals to which a power supply voltage of the vehicle is supplied. And reference numerals c, f, i, and l are ground terminals.

Referring to the operation state in which the length of the sunglasses sun visor 12 equipped with the control device as shown in FIG. 4 in the sunglasses sun visor 12 of the vehicle provided as described above is as follows.

During night operation, when the light from the headlamp shining from the headlight of the vehicle traveling in the other lane is incident on the light receiving surface of the phototransistor SW1 of FIG. 4, the phototransistor SW1 is saturated and "turned on". When the photo transistor SW1 is "turned on", the power supply voltage flows to the coil of the relay R1 through the limit switch SW3 in which the power supply voltage is "on", and the transistor SW2 is "turned off". Accordingly, the contacts a and b of the relay switch SW5 are connected to supply the forward rotation voltage to the first motor 14 so that the sunglasses sun visor 12 shown in FIG. 1 is rotated and positioned downward.

That is, the sunglasses sun visor 12 is rotated by the driving of the first motor 14 to protect the driver's view. When the first motor 14 is rotated and the position of the limit switch SW3 in the switch "on" state is reached, the limit switch SW3 is "off". Accordingly, when the first motor 14 is rotated and the sunglasses sun visor 12 is rotated to a preset position, the limit switch SW3 is “off” to stop the rotation of the first motor 14.

When there is no light incident on the light receiving surface of the phototransistor SW1 in the state where the sunglasses sun visor 12 is lowered as described above, the phototransistor SW1 is "off" and the transistor SW2 is "turned on". At this time, the relay R2 having a coil connected between the collector and the ground of the transistor SW2 is operated so that the contacts d and e of the relay switch SW6 are connected to drive the first motor 14 in the reverse rotation direction. By this operation, the sunglasses sun visor 12 is rotated in the reverse direction to return to its original position. When the first motor 14 is rotated to its original position and reaches the position of the limit switch SW4 in the "on" state, the limit switch SW4 is "off" to stop the rotation of the first motor 14.

Therefore, the sunglasses sun visor 12 having the control device as shown in FIG. 4 is automatically operated when intense light shines from the other's lane to protect the driver's view, and automatically returns when the light disappears from the other vehicle. To expand the driver's field of view.

On the other hand, the control device of the sunglasses sun visor 12 of the vehicle according to the present invention is operated to vary the length of the sunglass sun visor 12 unfolded by detecting the position of the driver's field of view, the specific operation details are as follows.

As described above, the field of view detector 62 shown in FIG. 4 is mounted on the inner side of the front roof of the vehicle to easily detect the driver's condition, particularly the position of the driver's eyes. First, when the position of the driver's field of view is detected by the field of view detector 62 while the sunglasses sun visor 12 is extended to the lower side by the driving of the first motor 14, the field of view detector 62 is located according to the detected height. Selectively drive relay R3 or relay R4 to rotate the second motor 36 forward or reverse.

For example, when the driver's field of view is detected to be lower than a predetermined height, the field position detector 62 drives the relay R3 to supply the forward rotation driving voltage of the relay switch SW7 to the second motor 36. If the driver's field of view is detected to be higher than a predetermined height, the field position detector 62 drives the relay R4 to supply the reverse rotation driving voltage by the relay switch SW8 to the second motor 36. In this case, the second motor 36 raises and lowers the position of the sunglasses sun visor 12 as shown in FIG. 3 according to the input of the forward rotation driving voltage or the reverse rotation driving voltage to lower the intensity of light reflected on the driver's field of view. Makes good.

Accordingly, it can be seen that the sunglasses sun visor 12 according to the above embodiment can be used regardless of the eye height according to the body type of various drivers by adaptively varying the position of the sunglasses sun visor by the visual position detector 62. have.

As described above, the sunglasses sun visor of the vehicle according to an embodiment of the present invention can make the night driving environment more quiet by eliminating the trouble of wearing sunglasses to block harmful light when the driver is driving at night. The driver's field of view can be automatically maintained from the headlight beam of the vehicle traveling on the side, and the transmittance of the light transmitted through the sunglasses sun visor can be varied depending on the terrain or road conditions.
