Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric sun/slizer for an automobile that is attached to the windshield of an automobile. Furthermore, if I were to comment, for example, the sun visor sheath and lower plate that shields direct sunlight from the windshield etc. are automatically operated by a signal from the sun sensor. This relates to an electric motorized sun visor for automobiles that can be lowered or rolled up by operating the sun visor. As is well known in the art, one end is fixed and a shaft member disposed approximately horizontally is rotatably supported on a shaft member so as to be able to pull down or pull up an insulating plate in the vertical direction, and the insulating plate is directly attached to the shaft member. It was constructed so that it could be used by manually pulling it down to a desired position, and then being pulled up and stored after use.

Problems to be Solved by the Invention A: With the above-mentioned conventional car sun visor, when it receives direct sunlight from the sun or when it is no longer needed, it is difficult to reach the upper part and position it in the desired position. Previously, it was a hassle to have to lower or raise the lower plate. Mr. Shika:For example, in places such as mountainous areas where the road has many twists and turns and changes direction relatively frequently, the presence or absence of direct sunlight changes frequently, and there is the inconvenience of having to operate the sun visor each time. Ta.

Alternatively, if the vehicle changes direction while driving around a sharp curve and is suddenly exposed to direct sunlight, it may become impossible to see the road ahead, causing unexpected danger. Furthermore, in places where the direction changes frequently as mentioned above, it is difficult to get used to lowering and raising the lower plate each time, so the driver may drive with the lower plate pulled down. For example, there have been problems such as difficulty in visually recognizing road signs indicating destinations, etc.

Means for Solving the Problems The present invention is intended to solve the above problems. That is, the lower plate of the sun visor is driven by a motor in response to a signal from a sun sensor or an operation switch, and is automatically lowered or rolled up by electrical operation. Therefore, for example, the configuration is such that a thin plate made of a semi-transparent resin material containing Freon is wrapped around it, and the rotation direction of the shaft member rotated by the motor drive is adjusted. The lower plate is lowered to the desired position,
Alternatively, it is stored and deployed in a case so that it can be rolled up, and furthermore, for example, the above-mentioned mirror is usually installed near the center of the upper front near the windshield. For example, a shaft member wrapped with a shield plate is installed with a motor, a driver circuit that controls the operation of the motor, and a sun sensor that detects the presence or absence of direct sunlight irradiation to rotate the shaft member via a belt. These components are connected in a relational manner via an automatic/manual changeover switch and an operation switch.

Function of the present invention The electric sun visor for an automobile according to the present invention constructed as described above operates as follows.

For example, when the changeover switch is operated to the automatic position, a sun sensor mounted opposite the windshield, for example, near the top of the rearview mirror, is connected to a dry no circuit that controls motor operation. And then,
When the sun sensor receives direct sunlight through the windshield, it sends out a predetermined signal to activate a driver circuit, which closes a predetermined electric circuit and rotates the motor. Then, the motor is connected to the motor through a bolt, and integrally rotates the left and right shaft members around which the lower plate is wrapped, and the lower plate is wrapped around the case. It operates until it is pulled out to a predetermined position to shield it from sunlight. When the base plate is pulled out to the specified position, the motor is stopped based on the command from the driver circuit, and the base plate is held in the 1 position while a signal is sent from the sun sensor and exposed to direct sunlight. This will cover up the situation.

Subsequently, when the sun sensor is no longer exposed to direct sunlight, no signal is sent from the sun sensor to the driver circuit, so the driver circuit is switched to an electric circuit that operates in reverse.

In this way, the motor is rotated in the opposite direction to the above-mentioned operation, so that the shaft member around which the sheath and low plate is wound is rotated in the direction to wind up the sheath and low plate.

Then, the low plate that got stuck on the windshield was rolled up again into the case and returned to its stored state. Thus, when the selector switch is operated to the automatic position, the low board is automatically pulled out as a sunshade depending on the presence or absence of direct sunlight on the sun sensor, and the
This function is to roll it up and store it. next,
When the selector switch is moved to the manual position, the sun sensor
The motor is separated from the driver circuit, and the motor is operated by manual operation of the operation switch, and the same operation as described above is performed to draw out or wind up the shingle base plate as desired.

Description of Examples 4-□I of the electric sun visor for automobiles according to the present invention
JG O, Onshotsu, Theory H'f 6゜1 is a case. The case 1 serves as a cover for accommodating the shaft member 2 and the bottom plate 3 wrapped around the shaft member 2, and is, for example, formed into a substantially cylindrical shape with an open end and an outer periphery. An elongated hole 1a corresponding to the width of the shroud plate 3 is formed in the surface along the axial direction for pulling out the shingle shield 1 wrapped around the shaft member 2 along the windshield 12. te↓ There is. Furthermore, in order to insert the case into the shaft member 2, for example, a hole is bored in the center of one bottom surface, and the other opening side is provided with a hole for the lid IC to be fitted into the opening. Hole 1 in the center
d is drilled. Thus, the case 1 has a shaft member (2%) supported on the front upper part near the windshield 12 of the driver's seat and the front upper part of the passenger seat, and a support member (9 not shown), etc. maintained and deployed.

2 is a shaft member. The shaft member 2 is housed in the case 1 with insulating plates 3 for the driver's seat and passenger seat wrapped around it on both sides, and is rotatable, for example, supporting members 10 and 1.
1 is accepted and supported. In the vicinity of the central portion of the shaft member 2, there are five IJ Q a attached, and the shaft member 2 is configured to be connected to the motor 5 by a belt 7 so as to be rotated.

3. It is a low board. The bottom plate 3 is made of, for example, a translucent plastic film having a predetermined elasticity and is wrapped around the shaft member 2. When the shield t is rotated in the direction shown in FIG. 1, the shield t is projected from the elongated hole 1a of the case 1 toward the windshield by a desired length.

Furthermore, the shaft member 2 is rotated in a direction opposite to the above direction. If not, it is rolled up again into case 1.

4 is a sun sensor. The sun sensor 4 detects the presence or absence of direct sunlight and sends a predetermined signal to the driver circuit 6. However, nuclear sun sensor 4
The mirror is installed at a position that is within the line of sight of the driver or passenger in the passenger seat, which is exposed to direct sunlight, for example, near the top surface of the rearview mirror 13, facing the windshield 12.

5 is a motor. A predetermined electric circuit is closed in the motor 5 by the operation of the driver circuit 6, and the motor 5 is rotated either in the forward direction or in the reverse direction. For example, it is installed near the upper surface of the rearview mirror in order to rotate the shaft member 2 wrapped around it. 6 is a driver circuit. The driver circuit 6 rotates the motor 5 in response to a signal from the sun sensor 4 or the operation switch 4. For example, when the changeover switch 9 is closed and operated to the automatic position A and the sun sensor is activated, the driver circuit 6 is configured such that when the sun sensor 4 receives direct sunlight, A timer circuit (not shown) is activated by the signal sent from the sun sensor 4, and is activated to rotate the motor 5 for a predetermined period of time. Furthermore, when there is no direct sunlight to the sun sensor 4, the signal from the sun sensor 4 stops, so the motor 5 is activated after a predetermined time lag.
The rotation direction is opposite to the rotation direction.

In addition, when the changeover switch 9 is opened and operated at the manual position M+C, the operation switch 8 is operated at the operation positions D1 and U.
It operates in order to operate the motor 5 according to the condition. The dry/<- circuit 6 can also operate the selector switch 9 to the automatic position A and operate the operating switch 8 even in the 1-position state to move the underseat plate 3 up and down to a desired position. 7 is a belt. The heald 7 is hung on the pulley of the motor 5 (-boo IJQa of the shaft member 2) and transmits the rotation of the motor 5 to the shaft member 2. 8 is an operation switch. The motor 5 is rotated by operating the operation switch 8, and the bottom plate 3 is pulled out or hoisted to a desired position.The operation switch 8 is normally set at the neutral position N.
is held at the drawer position and the winding position i of the lower plate 3.
This is an automatic type operation switch in which the operation positions of U are provided in opposite directions, and are installed near the driver's hand, for example. 9 is a changeover switch. The changeover switch 9 connects the sun sensor 4 and the driver circuit 6.
It is interposed between the two to open and close the space between them. That is, the closed position A is the automatic operation position where the sun sensor 4 is activated, and the open position M is the manual operation position where the drawer of the bottom board can be rolled up by operating the operation switch 8. It's the location.

As mentioned above, even when the changeover switch 9 is in the closed position 'UA', the operation switch or
8X can also be configured to operate. 10.
A support member 11 rotatably supports the shaft member 2. 12 is a windshield of a car.

Next, the operation of the above embodiment will be explained.

Now, for example, if you operate the changeover switch 9 to the automatic position A in a place where the direction of travel of a car changes drastically on a road in a mountainous area, and where the influence of direct sunlight is extremely frequent depending on whether the direction changes or not, When the sun sensor 4 receives direct sunlight, the driver circuit 6 is activated to rotate the motor 5. The motor 5 then rotates the shaft member 2 and pulls down the flap plate 3 wrapped around the shaft member 2 to a predetermined position. When the shield plate 3 is rotated for a predetermined time required to be lowered to a predetermined position, the motor is stopped by the operation of the timer circuit of the driver circuit 6. If the sun sensor 4 does not receive direct sunlight for a preset period of time, the driver circuit 6 rotates the motor 5 in the opposite direction to the direction of rotation, and lowers the lower plate 3.
Wrap it inside the case l again.

Thus, the electric sun visor for automobiles can automatically pull down and wind up the shield 3 in accordance with the presence or absence of direct sunlight, which frequently changes, without any manual operation by the driver. Do what you can.

Next, when the changeover switch 9 is operated to the manual position M, the sun sensor 4 and the driver circuit 6 are separated, and the operation is switched to the operation switch 8. That is, for example, by operating an operation switch 8 mounted near the driver's hand, the motor 5 is rotated via the driver circuit 6, and the sheath plate 3 can be lowered and hoisted. When the operation switch 8 is operated to the lowered position, the motor 5 is rotated only while the switch is turned on, and the barrier plate 3 can be lowered to the desired position. Here, when the shield plate 3 is completely lowered to a predetermined position, the motor 5 is stopped by the operation of the driver circuit 6 even if the operation switch 8 is in the ON state. Further, when the operation switch 8 is operated to the winding position U, the motor 5 is rotated only while the switch is on, and the lowering plate 3 can be rolled up to a desired position. Here, Shiya low plate 3
However, when the motor 5 is completely wound around the shaft member 2, even if the operation switch 8 is kept in the on state, the motor 5 is stopped by the operation of the driver circuit 6 in the same manner as described above. Furthermore, due to the configuration of the driver circuit 6, the operation switch 8 can be operated even when the changeover switch 9 is in the automatic position A. low plate 3
The lowering position or winding position fj! 1 can be adjusted as desired with the operation switch 8.

Effects of the present invention (a) Since the lower plate can be automatically lowered or rolled up depending on the presence or absence of direct sunlight, it is possible to avoid the hassle of using the sun visor frequently. Therefore, it is possible to provide an electric sun visor for automobiles that is extremely effective for safe driving.

(0) The lower plate can be lowered or raised as desired by operating an operation switch that can be installed near the driver's hand, so it is easy to operate while driving, and has excellent operability and is practical. It is possible to provide an electric sun visor for automobiles that is highly effective.

Since the e'lL and the lower plate are made of a translucent plastic film, the field of vision is not narrowed and it is possible to provide an electric sun visor for automobiles that does not get in the way even when the sun visor is in use.
