Description

[Detailed Description of the Invention] The present invention relates to a blind area visibility device for trucks, buses, and other automobiles.

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 rearview mirror and an under mirror outside the vehicle. Therefore, if there are people or bicycles within the blind area, the driver cannot see them, and the difference between the rear and rear wheels when turning left often causes accidents involving people or bicycles, which has become a social problem.

FIG. 1 is an old side 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 an under mirror C are installed, but the field of view with the main outside mirror B is B shown in Figure 3, and the field of view with the under mirror C is C, which is required for safety in Area Y notified by the Ministry of Transport. On the other hand, there is a blind area X.

Furthermore, since the under mirror C has a small curvature of 100 to 120 R, the image produced by the under mirror C is small and has a large distortion, resulting in poor visibility.

Furthermore, the images are reversed, making it difficult to obtain accurate positional relationships.

For this reason, blind area visibility devices that eliminate the above-mentioned blind areas and have good visibility are being developed. There is a risk that foreign matter may adhere to the image and reduce visibility.

In view of the above circumstances, the purpose of the present invention is to provide a blind area visibility device for automobiles that prevents raindrops etc. from adhering to the viewing area of the blind area visibility device and reducing the visibility of the device. do.

Embodiments of the present invention will be described below with reference to the drawings.

4 and 5 show a first embodiment of the present invention, in which the present invention is applied to a periscope-type vehicle blind area visual recognition device.

This blind area viewing device has an objective mirror 1 that captures the blind area that cannot be seen directly from the driver's seat, and an objective lens 2 that is arranged to make this image visible to the driver's eye point (EP). It is.

In the figure, IL 21 is a mirror body that supports each objective mirror 2, and 10 is a mounting.

A cover member 3 made of a cover glass is attached to a portion of the objective mirror 10 that serves as a window for the incident optical path of the target image.

In this example, a spoiler 4, which is a wind direction adjusting member, is disposed at the bottom of the cover member 3.

Specifically, in this example, a drip rail 16 is provided at the bottom of the cover member 3 to guide raindrops, and the spoiler 4 is fixed to the drip rail 16 with bolts 15 or the like.

In the illustrated example, drip rails 14 are also provided in the upper and side portions of Ujifugu 100 cover member 3, so that raindrops, etc. flow through these grooves to the drip rail 16 of cab roof 5. .

In this way, raindrops and the like will not adhere to the cover member 30 surface and will also not enter the inside of the housing.

At this time, the spoiler 4 of this example becomes substantially concave and clicks, changing the airflow into a laminar flow upward as shown by the arrow, as shown in FIGS. 5 and 6, and changing the constant flow to Since the running wind prevents water droplets from adhering to the device, water droplets and other foreign matter do not land on the device, so visibility is always maintained.

Nafu-1 In the figure, 7 is the backing, 8 is the finisher-19
is the main outside mirror.

Further, the visible area Z by the blind area visual recognition device of this example is shown in FIG. 8 as a button.

9 and 10 show a second embodiment of the present invention.

This includes an objective mirror 1 and an eyeglass (
) is housed therein, and a lens 8' is housed immediately inside the glass cover member 3 of this housing 10.
The spoiler 4 of this example has a substantially convex shape so as to cover the front side of the housing 10 (the side in the vehicle's sending-off direction), so that the airflow during driving is directed as shown by the arrow in the figure. ...The fluid flows in a laminar manner above and below the housing 10.

Furthermore, the fins 4' are attached to the bottom of the spoiler 4 in a trumpet-like manner, with the wide opening facing forward and a rapid airflow flowing from the narrow side, that is, from the rear. This prevents raindrops and other foreign matter from adhering to the front surface.

FIGS. 11 and 12 show a modification of the above example.

This is provided with an auxiliary member 41 for airflow rectification at the rear of the housing 10.

This auxiliary member 41 has a convex shape that tapers smoothly toward the rear, and serves to ensure that the traveling airflow flows smoothly.

That is, without this auxiliary member 41, turbulence as shown by arrow I in FIG. 12 would occur, but with this configuration, the traveling airflow is guided as shown by arrow W and flows smoothly.

Other components similar to those in the above example are given the same reference numerals and detailed explanations are omitted.

D indicates the direction of travel of the vehicle.

A third embodiment of the present invention is shown in FIGS. 13 and 14.

In order to prevent sunlight and other dazzling light from entering the objective lens, as well as to block rainwater and other obstacles, a mirror body 11 is extended from the objective mirror 1 to form a mirror hood. ) Gawani Spoiler-4
This is the one with the attached.

Further, a fin 4' is attached to the lower part of the spoiler 4, and airflow is made as shown by the arrow in the figure in the same manner as in the previous example.

The button 14 in the figure is a drip rail provided around the mirror body 11, and 14' is a hole provided at the lowermost end behind it to drain rainwater.

Further, 23 is a stay, 25 is a bracket for mounting the objective mirror 1, 26 is a backing installed between the peripheral edge of the objective mirror 10 and the mirror body 11, and D is the direction of travel of the vehicle.

As described above, the present invention provides a blind area viewing device for automobiles having an objective mirror for capturing the blind area and pair of glasses arranged so as to make the image captured by the objective mirror visible. A wind direction adjustment member is attached to the front side of the objective mirror in the direction perpendicular to the vehicle, and the wind direction adjustment member guides the traveling wind in a laminar flow to a position having a distance from the mirror surface of the objective mirror or the cover member of the housing, The laminar running wind prevents the adhesion of foreign substances such as raindrops and dust that reduce visibility, so it is possible to prevent water droplets and foreign substances from attaching to the cover member or mirror of the blind area visibility device. This has the effect of preventing the adhesion of particles and maintaining good visibility.

In addition, in the illustrated pot example-1, a drip rail is provided on the cover member and the mirror hood to prevent raindrops from adhering to the pot, but the present invention is not limited to this embodiment.
