Description

[Detailed Description of the Invention] The present invention relates to a visual recognition device for trucks, buses, and other motor vehicles.

In the case of large trucks and other vehicles in which the driver's seat is located in a high position, there is a blind area on the left side of the driver, even though the vehicle is equipped with a main outside mirror and an under mirror outside the vehicle. Therefore, if there were people or bicycles within the blind area, the driver would not be able to see them, and there was a risk that the difference between the inner wheels when making a left turn could cause an accident, such as involving a person or bicycle.

First, a conventional visual recognition device will be explained with reference to FIGS. 1 and 2.

Note that FIG. 1 is a front view of a part of a conventional truck, and FIG. 2 is a side view of the same.

As shown in these figures, in trucks, etc., the main outside mirror b is attached to the stay a that projects outside.
and under mirror C are installed.

However, the field of view with the main outside mirror b is B shown in FIG. 3, and the field of view with the under mirror C is C, and there is a blind area Y with respect to the area X required for safety.

In addition, the image produced by the under mirror C has the disadvantage that the image is small and the image distortion is large because the curvature of the under mirror is thick, resulting in poor visibility.

For this reason, mirror devices with good visibility that eliminate the above-mentioned blind area are being developed using mirror systems that combine various mirrors. If the glasses are installed, it is necessary to configure the glasses so that the occupant does not get injured by colliding with the glasses.

The present invention was devised in view of the above, and is located at the upper part of the front corner of the driver's cab of the automobile, near the corner farthest from the driver's seat, and covers the front lower part of the vehicle body and the lower side of the vehicle body farthest from the driver's seat. comprising an objective mirror consisting of a convex mirror serving as a field of view, and eyeglasses positioned near the dash board in the driver's cabin to allow the driver to visually recognize the image of the objective mirror,
A cover is disposed near the eyeglasses and is integrally formed with a member forming the dash board to prevent an occupant from colliding with the eyeglasses, and the cover serves as a light path from the objective mirror to the eyeglasses. The gist of this invention is a visual recognition device for an automobile, characterized in that an optical aperture is formed in a portion that serves as an optical path from the pair of glasses to the driver.

Embodiments of the present invention will be described below with reference to FIGS. 4 to 12.

First, a first embodiment will be described with reference to FIGS. 4 to 1.

An objective mirror 6 is located at the upper part near the left corner of the front part of the driver's cab 4 of the vehicle body 2 of the automobile in which the driver's seat is on the right side.
Eyeglasses 10 are positioned near the dash board 8 inside.

The objective mirror 6 is located in the area D shown in FIG.
It is a convex mirror with a field of view of the front lower part and left side lower part of the mirror, and is attached to a stay 14 that supports the main outside mirror 12 whose field of view is area E.

The eyeglasses 10 allow the driver to view the image of the objective mirror 6, and are attached to an inner panel 16 that covers the base of the dash board 8.

A crash pad 18 made of an elastic body mounted on the inner panel 16 has an opening 18a or an opening 18a in a portion that becomes an optical path from the objective mirror 6 to the eyeglasses 10.

An opening 18b is formed in a portion that becomes an optical path from the mirror 10 to the driver's eye point, and as a result, both openings 18b
A cover portion 18c that is integral with the crash pad 18 is formed between and 18b.

Note that a core member 20 supported by the inner panel 16 is disposed on this cover portion 18c.

According to the above configuration, it is possible to completely cover the blind area Y in FIG.
Since the image is seen by the driver through 0, the image seen by the driver is a normal image, and the angle of incidence and reflection in the convex mirror objective mirror 6 is compared with the under mirror C in FIGS. 1 and 2. can be set very small, and image distortion is greatly reduced.

Further, even if the occupant is thrown toward the eyeglasses 10 due to a vehicle collision, etc., the cover portion 18c prevents the occupant from colliding with the eyeglasses 10.

The cover portion 18c in the above embodiment is not limited to the shape shown in FIGS.
It is also possible to have a shape like the modified example shown in the figure.

In addition, in the case shown in FIG. 8, the cover part 18c is formed in a protruding shape with respect to the dash board 8 and integrally with the crash pad 18, and the edge of the opening 18b is colored, so that the driver can This allows the position of the opening 18b to be easily known.

Next, a second embodiment of the present invention will be described with reference to FIGS. 9 to 11.

Note that the same or substantially the same parts as those in the first embodiment are given the same reference numerals as used above, and detailed explanations thereof will be omitted.

In this embodiment, the same objective mirror 6 as in the first embodiment is used.
However, the pair of eyeglasses 10 has a dash board 8.
The lid 20 is housed in a case 22 having a lid 20 made of a transparent material. A coating film or sheet 24 is applied to the outer surface (or inner surface) except for the portion that becomes the optical path to the point.

According to the above configuration, similarly to the first embodiment, the lid 20 can prevent the occupant from colliding with the eyeglasses 10 and dust from adhering to the eyeglasses 10. Thus, when the eyeglasses 10 are supported via the drive device 26 for adjusting the angle of the eyeglasses 10, maintenance and inspection of the drive device 26 can be easily performed.

It should be noted that the coating film or sheet 24 prevents unnecessary light from entering the eyeglasses 10.
This is to prevent the light from entering the driver's eyes, but this effect can be further improved by providing a shade 28 inside the lid 20 along the optical path, as in the modified example shown in FIG. It can be made into something.

As described above, according to the present invention, it is possible to obtain an excellent visual recognition device that can provide a clear field of view necessary for safety and can also prevent injuries to passengers.
