Description

  The present invention relates to a vehicle with a rear under mirror.

Some vehicles have a rear under mirror provided in the vehicle interior, and enable indirect viewing in which the rear lower mirror visually recognizes the rear lower side of the vehicle (see, for example, Patent Document 1).
In addition, by attaching a black film to the rear window glass on the vehicle, the light transmittance is reduced, and the visibility for direct viewing through the rear window glass from outside the vehicle compartment is reduced, thereby protecting privacy. There is something that aims at.
Japanese Utility Model Publication No. 1-175944 (1st page, FIG. 1)

  However, in the rear downward visual recognition device of Patent Document 1, when a film that protects privacy is attached to the rear window glass, the film is reflected on the rear under mirror and the film is visually recognized. In any case, there is a problem that the visibility of indirect viewing is also lowered.

  In addition, there are some films that are stripped and affixed separately to the rear window glass so that they appear as lines on the rear under mirror, which can be used as a guide when parking and stopping. There is a problem that the two films stuck on the glass are visually recognized to form a blind spot, and the direct visibility is deteriorated.

  In the present invention, even if a viewing angle adjustment film is pasted on the rear window glass, the viewing angle adjustment film cannot be visually recognized on the rear window glass by direct visual recognition. In the indirect visual recognition, the viewing angle adjustment film can be visually recognized on the rear under mirror. On the other hand, in the direct visual inspection, the viewing angle adjustment film can be visually recognized. It is an object of the present invention to provide a vehicle with a rear under mirror in which the viewing angle adjustment film cannot be visually recognized.

  The invention according to claim 1 includes direct visual recognition in which the rear is visually recognized through the rear window glass at the rear of the vehicle, and indirect visual recognition in which the rear lower portion is visually recognized through the rear under mirror provided in the vicinity of the rear window glass and in the vehicle interior. In a vehicle with a rear under mirror that can be viewed rearward at the rear window glass, by providing a viewing angle adjustment film on the rear window glass that can be viewed according to the viewing angle and an invisible state that is not visible, direct viewing or indirect viewing The viewing angle adjustment film is not visually recognized in a visually invisible state when either one is visually recognized, and the viewing angle adjustment film is visually recognized in a visually visible state with the other visually recognized.

  The invention according to claim 2 is characterized in that the viewing angle adjusting film is set to a viewing angle that is visually recognized in a visually recognizable state during direct viewing and is not visually recognized in an invisible state during indirect viewing. .

  The invention according to claim 3 is characterized in that the viewing angle adjusting film is set to a viewing angle that is not visually recognized in a visually invisible state and is visually recognized in an invisible state when indirect viewing. And

  In the invention according to claim 1, the vehicle with a rear undermirror is provided with a viewing angle adjustment film on the rear window glass that can be viewed by a viewing angle and a viewing angle adjustment film that is not visually recognized. The viewing angle adjustment film is not visible in the invisible state in one of the visual recognitions, and the viewing angle adjustment film is visible in the visible state in the other visual recognition. Even if affixed, the viewing angle adjustment film cannot be visually recognized on the rear window glass by direct visual recognition, and the viewing angle adjustment film can be placed on the rear under mirror for indirect visual recognition through the rear under mirror. The viewing angle adjustment film can be viewed in direct viewing. Rukoto can be, there is an advantage in that it is not possible to visually recognize the viewing angle adjustment film to the rear under mirror in indirect viewing.

In the invention according to claim 2, since the viewing angle adjusting film is set to a viewing angle that is visible in a visible state during direct visual recognition and is not visible in an invisible state during indirect visual recognition, The viewing angle adjustment film can be visually recognized, and there is an advantage that the viewing angle adjustment film cannot be visually recognized on the rear under mirror by indirect viewing.
For example, when the viewing angle adjustment film is used as privacy protection, the viewing angle adjustment film is visually recognized, so that the line of sight from the outside of the vehicle can be blocked, and privacy protection can be achieved.
When a character is formed and used with the viewing angle adjusting film, a person outside the vehicle can read the character by visually recognizing the viewing angle adjusting film.
When the occupant visually recognizes the rear lower part of the vehicle indirectly through the rear under mirror, the viewing angle adjustment film is not visually recognized by the rear under mirror, and thus the visibility of the rear lower part can be ensured.

In the invention according to claim 3, since the viewing angle adjustment film is set at a viewing angle that is not visually recognized in a visually invisible state and is visually recognized in a visually visible state in indirect viewing, The visual angle adjustment film cannot be visually recognized by visual recognition, and the visual angle adjustment film can be visually recognized by the rear under mirror by indirect visual recognition.
For example, when a belt-shaped viewing angle adjustment film is pasted on the rear window glass as a guideline for parking and stopping, the occupant cannot directly see the viewing angle adjustment film when viewing directly, so it is equivalent to the state without the viewing angle adjustment film. A visual field can be secured.
When the occupant visually recognizes the rear lower side of the vehicle indirectly through the rear under mirror, the viewing angle adjusting film is visually recognized on the rear under mirror, so that it can be projected as a belt-like line on the rear under mirror.
That is, the viewing angle adjustment film can be used as a guide when parking and stopping.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is a side view of a vehicle with a rear under mirror according to the present invention (first embodiment).
A vehicle with a rear under mirror (first embodiment) 11 has a rear under mirror 13 on a rear 12.
The vehicle 11 includes a wheel 16, a passenger compartment 17, a driver seat 21 provided in the passenger compartment 17, a driver seat 22, a rear seat 23, a rear body 24, a rear window glass 26 fitted to the rear body 24, and a rear window glass 26. A rear under mirror 13 is provided above.

  In addition, the vehicle 11 has a direct visual recognition (reflected light indicated by an arrow a3) through the rear window glass 26 behind the vehicle 11 (in the direction of the arrow a1), the vicinity of the rear window glass 26, and the interior of the vehicle compartment 17. It is a vehicle that can be visually recognized rearward by indirect visual recognition (reflected light of arrow a4) that visually recognizes the rear lower side through a rear under mirror 13 provided in the vehicle.

  The rear under mirror 13 is a mirror that is used when the occupant M of the driver's seat 21 looks rearward and visually recognizes the rear lower side (the direction of the arrow a5) of the vehicle 11 and projects the rear lower visual recognition range 27.

FIG. 2 is a view taken in the direction of the arrow 2 in FIG. 1 (first embodiment), and shows a state visually recognized by the rear under mirror 13.
In the rear under mirror 13, the viewing angle adjusting film 31 attached to the rear window glass 26 is displayed as a line 32. This reflected line 32 is used as a guideline for parking and stopping as an auxiliary line.

The rear under mirror 13 is an existing one, and includes a support portion 41 attached to the roof 35 of the vehicle body 34 at the rear of the vehicle compartment 17, an adjustment portion 42 provided at the tip of the support portion 41, and an adjustment portion 42. And a mirror 44 held by the holding portion 43. The adjusting part 42 is a part that rotatably supports the holding part 43 so that the angle of the mirror 44 can be adjusted. Although the mirror 44 is a convex mirror, it may be a plane mirror depending on conditions.
“Adjustable angle” means that the angle can be adjusted in the A-axis direction, the B-axis direction, and the C-axis direction.

The viewing angle adjustment film 31 is obtained by incorporating a fine light regulating plate S (see FIG. 3) inclined at a predetermined angle into an acrylic or PET (polyethylene terephthalate) film, and depending on the adjustment angle of the light regulating plate S, Depending on the viewing angle, the viewing angle adjusting film 31 can be seen or not seen.
Further, by changing the light transmittance of the light regulating plate S, a light-shielding plate with a transmittance of 0% or a transflective plate with a transmittance of 50% can be obtained.

  The viewing angle adjusting film (first embodiment) 31 is a rear window glass at a position, an angle, and a film width Wf that are reflected on the rear under mirror 13 as a line 32 that serves as a guide for the width (X-axis direction) of the vehicle 11. 26 is affixed to the inner surface 46 of 26.

The viewing angle adjustment film 31 is affixed symmetrically with respect to the center Cw of the vehicle width of the vehicle 11, the left belt-like film body 47 is stuck at an angle θf, and the right belt-like film body 48 is attached. It is pasted at an angle θf.
The film width Wf is arbitrary.

  FIG. 3 is a sectional view taken along the line 3-3 (first embodiment) in FIG. 2 and schematically shows a section of the viewing angle adjusting film 31 (first embodiment). The position of the eye E (eye point) is the position shown in FIG.

  Depending on the viewing angle, the viewing angle adjusting film 31 may or may not be visible. Specifically, the light regulating plate S is adjusted to an angle α that is an angle with respect to the reference axis B parallel to the horizontal plane. When the angle α of the light restricting plate S is set to 0 ° (the light restricting plate S is parallel to the horizontal plane), the light restricting plate S does not restrict the incidence of the light 51 parallel to the horizontal plane. That is, it is equivalent to a transparent film.

  Here, since the angle (viewing angle) α of the light restricting plate S is adjusted to approximately 0 ° (parallel to the horizontal plane), the viewing angle adjusting film 31 transmits the incident light 51 parallel to the horizontal plane without regulating it. However, the incident light 52 that is not parallel, for example, the incident light 52 having an angle θ (θ is about 60 °) with respect to the horizontal plane, is regulated by the light regulating plate S. That is, the film does not transmit (or semi-transmits) the incident light 52.

  Next, the operation of the vehicle with the rear under mirror (first embodiment) 11 of the present invention will be described. A mechanism when the rear lower part of the vehicle 11 with the rear under mirror (first embodiment) 11 is visually recognized will be described with reference to FIGS.

When the occupant M of the driver's seat 21 directly views the rear of the vehicle 11 (in the direction of the arrow a1) toward the rear window glass 26, the viewing angle adjusting film (first implementation) with respect to the position of the eye E (eye point) ) 31 does not regulate light from the rear, so that the occupant M cannot visually recognize the film body 47.
That is, since the viewing angle adjusting film 31 transmits the light 53 from the rear landscape with respect to the position (eye point) of the eye E, the film main body 47 and the film main body 48 do not hinder the visual recognition of the rear view.

In addition, the viewing angle adjusting film 31 is configured such that when the occupant M of the driver's seat 21 visually recognizes the lower rear side (the rear lower visible range 27) of the vehicle 11 using the rear under mirror 13, the light regulating plates of the film main body 47 and the film main body 48 are used. Since S regulates the incidence of the incident light 52 and the reflected light 56 of the light regulating plate S itself is reflected by the rear under mirror 13 toward the eye E, the film main body 47 and the film main body 48 are visually recognized.
That is, the film main body 47 and the film main body 48 appear as lines 32 on the rear under mirror 13.

  Thus, in the vehicle 11 with the rear under mirror (first embodiment) 11, even if the viewing angle adjustment film (first embodiment) 31 is pasted in a belt shape, the viewing angle adjustment film (first embodiment) 31 The rear viewing mirror 13 (first embodiment) 31 can be projected on the rear under mirror 13 when the rear can be visually recognized in the same manner as the case where the film is not pasted. Therefore, an auxiliary line can be formed as a guideline for parking and stopping.

  In the vehicle 11 with the rear under mirror, since the viewing angle adjusting film (first embodiment) 31 is pasted on the rear window glass 26, even if the angle of the rear under mirror 13 is adjusted, the auxiliary line is positioned at a substantially constant position. Can be reflected.

Next, another embodiment will be described.

  The viewing angle adjustment film 31B of the second embodiment is characterized in that the angle (viewing angle) of the light regulating plate SB of the viewing angle adjustment film 31B is set to αb. The viewing angle adjusting film 31B has an angle αb of the light restricting plate SB set to about 40 °, restricts the incident light 61 parallel to the horizontal plane and does not transmit the non-parallel incident light 62, for example, the horizontal plane. Thus, the incident light 62 having an angle θ (θ is 40 °) is transmitted without being restricted. That is, the film is transparent when viewed from the position of the rear under mirror 13.

Next, the operation of the second embodiment will be described.
In the vehicle 11B with a rear under mirror according to the second embodiment, when the occupant M of the driver's seat 21 directly looks at the rear of the vehicle 11B (in the direction of the arrow a1) toward the rear window glass 26, the position of the eye E ( Since the viewing angle adjusting film (second embodiment) 31B regulates the light from the rear of the vehicle, the occupant M is viewing the film body 47B.
That is, the viewing angle adjusting film 31B regulates and does not transmit (or semi-transmits) the light 64 from the rear landscape with respect to the position of the eye E (eye point) and the light 61 leaking from the vehicle interior to the rear of the vehicle. Therefore, the line of sight from the outside of the vehicle can be blocked, the visibility of the passenger compartment from the vehicle behind can be lowered, and privacy can be protected.
At this time, if the light transmittance of the light regulating plate SB is a semi-transmissive plate of about 50%, the occupant M can visually recognize the rear.

The viewing angle adjustment film 31B does not generate reflected light from the film main body 47B when the passenger M in the driver's seat 21 visually recognizes the rear lower side (rear and lower visual recognition range 27) of the vehicle 11B using the rear under mirror 13. The film main body 47B cannot be visually recognized.
That is, since the viewing angle adjustment film 31B transmits the reflected light 65 from the object in the rear lower part (the rear lower visual recognition range 27), the rear lower part (the rear lower visual recognition area 27) can be visually recognized.

  As described above, in the vehicle 11B with the rear under mirror according to the second embodiment, even if the viewing angle adjustment film 31B is pasted, the rear under mirror 13 is used for the vehicle 11B even if the viewing angle adjustment film 31B is not pasted. The rear lower visual recognition range 27 at the lower rear can be viewed.
