Description

[Detailed Description of the Invention] Purpose of the Invention [Industrial Application Field] The present invention relates to a sun visor device attached to the upper part of the front seat of an automobile, and in particular, the present invention relates to a sun visor device that is attached to the upper part of the front seat of an automobile. This is designed to block light at an appropriate position and to reduce the possibility of blocking the driver's view when the light is blocked.

[Conventional technology]

A sun visor device is installed above the windshield inside a car so that the person sitting in the driver's seat or passenger seat (hereinafter referred to as the driver) can avoid the glare of sunlight.

Conventionally, a general automobile sun visor device has a light shielding plate (3) supported by a shaft at the upper part of each side of the driver's seat and passenger seat at the front glass (1 and 11 parts), as shown in FIG. (
In step 3), when shielding light, it is rotated around the shaft (121) and lowered vertically, and when stored, it is raised horizontally along the ceiling surface (10).

The size of this light shielding plate (3) is usually about 40 to 50 cm in width, which is nearly half the width of the windshield (1), and about 12 to 13 cm in vertical width. Note that since the direction of sunlight irradiation is from the side, the light shielding plate (3) is also rotatable laterally by the shaft side.

[Problem to be solved by the invention]

The light shielding plate (3) of the conventional automobile sun visor device described above cannot be moved from a horizontal position when stored to a vertical position when shielding light, or from a vertical position to a horizontal position after use, or when the direction of sunlight irradiation is lateral. In this case, the driver or the like had to manually move the vehicle from the front position to the side position, or from the side position to the front position if the vehicle was in the front position.

However, these days, drivers and others are wearing seatbelts, making it difficult for them to move their bodies. Even if you try to move the light shielding plate (3) at the top of each reclining seat such as the driver's seat, it may be difficult to reach depending on the driving position. Especially if you are a small person, a woman, or a person with a physical disability, the light shielding plate (3
) was even more difficult to reach.

Further, the conventional light shielding plate (3) is formed in a large size in order to cope with changes in the direction of sunlight irradiation. This is because when the direction of travel of the car changes, the direction of sunlight irradiation also changes.
This is because if the light shielding plate (3) is small, it will not be able to exhibit a light shielding effect. Since the light shielding plate (3) is large in size, a large portion of the upper part of the driver's field of vision is blocked by the light shielding plate (3) while the driver is using the light shielding plate (3). There were problems such as it was difficult to see, and it was difficult to drive while looking into the distance on the expressway, which hindered safe driving.

The present invention aims to solve the problems of the conventional sun visor devices for automobiles.

That is, an object of the present invention is to provide a system that allows drivers to use the system easily, that allows them to always obtain light shielding even when the direction of sunlight irradiation changes, and that allows them to drive safely without obstructing their visibility even when the light is shielded. An object of the present invention is to provide a sun visor device for automobiles.

Structure of the Invention [Means for Solving the Problems] A sun visor device for an automobile according to the present invention includes a guide strip (2) installed horizontally from the top to the side of a windshield (1) inside the automobile. The support member (4) of the light shielding plate (3) is attached to the guide strip (2).
), and is provided with a drive means (5) for moving the light shielding plate (3) left and right along the guide strip (4), and the drive means (5) is adapted to change the direction of sunlight irradiation. A light sensor (6) is provided to detect the direction of sunlight irradiation so as to be able to follow the direction of sunlight.

In the above configuration, it is desirable that the sun visor device of the present invention be provided independently on the driver's seat side and the auxiliary seat side.

The driving means (5) is capable of moving the light shielding plate (3) in the left-right direction along the guide strip (2), and is driven by a motor (8).
).

As for the size of the light shielding plate (3), it is preferable that the vertical width is about the same as the conventional one, and the horizontal width is, for example, about ⅓ of the conventional one.

In addition, to start the operation, the drive means (5) is turned on by lowering the light shielding plate (3) and making it vertical.After that, it is better to move it left and right according to the instructions of the optical sensor (6), but the operation starts. may be performed by turning on an electric switch (not shown) at hand.

To complete the operation, it is preferable to turn off the switch so that the driving means (5) returns the light shielding plate (3) to its original position, and then store it horizontally by hand. However, the driving means (5) may return the light shielding plate (3) to its original position without turning off the switch if the light shielding plate (3) is placed in a horizontal position.

[For production]

The usage conditions of the automobile sun visor device according to the present invention are as follows.

At the position 2), it is sufficient to leave it in the horizontal storage state along the indoor ceiling surface 00). In addition, if the operation is started using a switch at hand, it can be left in the OFF position.

In addition, the light-shielding plate (3) at that time should be 11 so that it does not obstruct the view at all.
) Next, if the driver, etc. feels dazzled by sunlight coming from the front or side, the driver, etc. should place their hand (right hand for the driver, left hand for the passenger) on the upper side of the driver's seat or passenger seat. Stretch out each light shielding plate (3)
All you have to do is lower it from a horizontal position to a vertical position that can block light. The drive means (5) now starts operating.

If the device starts operating with a switch, all you have to do is turn on the switch at hand.

In the above case, each light shielding plate (3) is located at the upper side of the driver's seat, etc., so it is in a position where the driver, etc. can easily reach it.
It is easy to operate even for small people.

Thereafter, each optical sensor (6) detects the irradiation direction of sunlight and sends it as an electric signal to each driving means (5). In response to this signal, the driving means (5) moves each light shielding plate (3) left and right along the guide strip (2) and stops it at a position where sunlight is shielded when viewed from the driver's or passenger's seat. Become.

This allows drivers to drive without the glare of sunlight.

iii) When the direction of sunlight irradiation changes as the vehicle moves, the driver and the like do not need to perform any operations. Light sensor (

Effects of the Invention As is clear from the above description, the automobile sun visor device according to the present invention can be easily used by a driver, etc., and can always block sunlight even if the direction of sunlight changes. This allows safe driving without obstructing visibility even when the light is blocked.

That is, in the conventional sun visor device for an automobile, a light shielding plate is pivotally supported on the front upper part of the driver's seat or the like. Therefore,
In general, it is difficult to reach the light shielding plate, especially for small people and women.
For people with physical disabilities, it was even more difficult to reach. On the other hand, since the light shielding plates are made large, a large part of the field of view is blocked when the light is blocked, making it difficult to see traffic signs and traffic lights, and making it impossible to drive while looking into the distance on expressways, which impedes safe driving. Sometimes it became.

On the other hand, the automotive sun visor device of the present invention has
Since the light shielding plate is located on the side stop close to the driver, it is easy for even small people such as the driver to reach it.

After that, it automatically starts operating, and the driving means moves the light shielding plate to the appropriate position using the optical sensor, making operation very easy.

Furthermore, even if the direction of sunlight changes, the optical sensor detects the change and automatically moves the light shielding plate to follow, so the driver can always block sunlight without being dazzled.

Moreover, since the light shielding plate automatically follows changes in the direction of sunlight irradiation, the light shielding plate can be made smaller. Therefore, the visibility is less obstructed when the light is blocked, and drivers can see traffic signs and traffic lights better, and can see far away even on expressways, allowing them to drive safely.

Although the sun visor device according to the present invention has been described for use in automobiles, it can also be provided above the cockpit or driver's seat of an aircraft, ship, train, etc., and the same effect as above can be obtained in those cases as well. It will be played.
