Description

Shading device for automobiles {SHADING THE LIGHT MEANS OF VEHICLE}

The present invention relates to a light shielding device of an automobile.

In general, many obstacles are generated in the process of driving a car, which hinders the driver's driving. One of such obstacles will be the sunlight incident through the wind shield glass.

Therefore, as shown in FIG. 3, the windshield glass 3 is rotated while the driver rotates the sun visor 2 by pivotally installing the sun visor 2 on the roof panel 1 adjacent to the driver's seat through the pivot arm 4. ) To block sunlight from entering.

However, in such a light shielding device, the sun visor 2 needs to be adjusted while the sun visor 2 is rotated around the roof panel 1, thereby causing inconvenience in use, and also the sun visor 2 during the driving process. There is a problem in that it is difficult to cope with a dangerous situation by performing the operation of rotating the motor and cause a crash or the like.

The present invention was created in order to solve the above-mentioned conventional problems, and by automatically changing the position of the sun visor main body automatically according to the position of the sun, it is not only easy to use but also particularly capable of driving stability of the vehicle. The purpose is to provide a light shielding device.

In order to achieve the above object, the present invention includes a bracket that is built-in on the roof panel, the guide groove is formed on the inner surface; A sun visor main body having a rod detecting the position of the sun in a vertical direction at a predetermined interval on a front surface thereof, and having a rod inserted at one end to be slidably inserted into a guide groove of the bracket; Control means for varying the position of the sun visor body according to the position of the sun sensed by the position sensor.

1 is a perspective view of a vehicle employing a light shielding device according to the present invention.

2 is a block diagram conceptually showing an operating state of the present invention.

3 is a perspective view of a vehicle employing a light shielding device of a conventional vehicle.

40: control means 41: controller 42: step motor

43: pinion 44: rack

As shown in FIGS. 1 and 2, a bracket 20 having a guide groove 21 formed therein is installed on a roof panel 10 adjacent to a driver's seat and a passenger seat.

And a rod 31 is provided so that the guide groove 21 of the bracket 20 can be slidable from one end of the sun visor main body 30 which substantially shields light.

In addition, on one side of the sun visor main body 30, a plurality of position detection sensors 32 for detecting the position of the sun in the up and down directions are installed at a predetermined interval.

As the position sensor 32, it is preferable to use a photosensor.

And the control means 40 for changing the position while moving the sun visor main body 30 up and down according to the position of the sun sensed by the position sensor 32 is provided.

In the detailed structure of the control means 40, the controller 41, the step motor 42, the pinion 43 and the rack 44 is composed of.

The controller 41 is connected to the position sensor 32 on the sun visor body 30 as described above, and performs a function of detecting the position of the sun through the amount of light received by the position sensor 32. .

The step motor 42 is driven by a predetermined step in the forward and reverse directions according to the position of the sun sensed by the controller 41, and the pinion 43 is coupled to the rod end thereof to rotate the drive.

The rack 44 is provided on one side of the sun visor body 30, and is engaged with the pinion 43 while being positioned inside the roof panel 10 so that the entire sun visor body 30 is rotated according to the rotation of the pinion 43. ) To move up and down.

According to the present invention configured as described above, when sunlight is incident through the windshield glass 3 during the driving of the vehicle, the position of the sun visor main body 30 is automatically adjusted according to the position of the sun so that the driver can drive stably. It can be done.

In more detail, when the solar light is incident through the windshield glass 3, the photosensors arranged in up and down directions on one side of the sun visor main body 30, that is, the position detecting sensor 32 are The position of the sun is detected through the difference, and the controller 41 recognizes this position.

When the position of the sun is recognized by the controller 41 as described above, the step motor 42 connected to the controller 41 is selectively driven in the forward and reverse directions to rotate the pinion 43, and the pinion 43 And the engaged rack 44 is moved to the inside, the outside of the sun visor body 30 is to change its position in the up, down direction.

At this time, the rod 31 is provided on the other side of the sun visor main body 30, and the rod 31 is slidably transported without flow by being transferred along the guide groove 21 of the bracket 20 on the roof panel 10. do.

As described above, according to the present invention, the sun visor is automatically operated according to the degree of incidence of sunlight incident through the wind shield glass, and the position thereof is changed to perform the shading operation while not only for convenience of use, but also for shading by manual light. There is an advantage that can prevent in advance the risk of collision accident that may occur during operation.

Therefore, there is an advantage that can further satisfy the consumer's satisfaction with the car employing it.
