Description

  The present invention relates to a sun visor device including a surface illumination and a mirror for blocking light entering a vehicle interior.

  2. Description of the Related Art Conventionally, a vehicle sun visor device is known as a movable sunshade used by being mounted inside a front (or side) window of a vehicle such as an automobile.

  The sun visor used in this type of vehicle sun visor is a frame or base material such as plastic covered with a shock absorbing material such as foamed plastic, or further covered with an exterior material such as a plastic sheet. It is mounted on the upper part of the vehicle windshield mainly by a guide bar so as to be swingable. A plate-shaped sun visor, which is basically rectangular or trapezoidal (hereinafter simply referred to as a visor if necessary), is swung to the roof side of the vehicle in the housed state, and from there to the windshield side When it is swung, it covers the top of the windshield.

  Conventionally, in this type of vehicle sun visor device, a mirror (vanity mirror: so-called makeup mirror) is mounted on the visor surface facing the occupant (or driver) when the visor is lowered. Yes. This mirror is normally covered except when it is used by a rocking or sliding lid. Alternatively, there is known a device provided with a lighting tool for use in a mirror or for assisting indoor lighting.

  The illuminator and the mirror are arranged on the same surface of the visor body, and face the occupant when the visor is swung down from the accommodation position. In this state, the mirror and the illuminator are used.

  However, since this illuminator irradiates the occupant from a position facing the occupant, the light from the illuminator may directly enter the occupant's eyes, which may make the occupant feel dazzling. In view of this point, for example, a sun visor device having a configuration of a main visor provided with a mirror and a sub visor provided with a lighting device has been proposed (Patent Document 1 below).

JP 2003-34138 A

  The illumination and the sun visor with mirror described in Patent Document 1 are based on the technical idea that the light from the front is dazzling and irradiates from another position. However, in the configuration of Patent Document 1, the mirror occupant faces the passenger. Because the angle and the illumination angle of the secondary visor are far apart, when using a mirror for retouching in the passenger compartment at night, it is difficult to understand the front of the face, which is not practical. In applications such as makeup retouching, it is desirable that the light is emitted from the front, and the problem of passengers' dazzling is considered to be almost solved by causing the light to emit light so as not to be dazzled.

  In addition, when a lighting fixture is arranged on the sun visor, its power supply and wiring also become a big problem. For example, since the position of the sun visor changes frequently depending on the angle of the sun, drawing the wiring for lighting from the vehicle battery is not an appropriate structure in terms of durability and cost.

  The subject of this invention is providing the sun visor apparatus for vehicles which is excellent in the utility of a mirror and a lighting fixture in view of said problem, and has an appropriate structure regarding wiring and electric power feeding.

  Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

  1 to 4 show an embodiment of a vehicle sun visor device adopting the present invention. FIG. 1 is a folding (accommodating) position (first position: hereinafter referred to as A position) of the vehicle sun visor device of the present embodiment, and FIGS. 2 and 3 are vehicle sun visors of the present embodiment. The apparatus is shown in a deployed position (second position: hereinafter referred to as B position). FIG. 4 shows a cross-sectional structure of the vehicle sun visor device of this embodiment.

  1 to 3, reference numeral 3 denotes a guide bar, and the right end 3a shown in the figure is fixed to the roof (ceiling) of the vehicle. The sun visor body 1 is supported by the guide bar 3 so as to be swingable (in the directions A and B), and for example, some friction mechanism is incorporated so that the sun visor body 1 can be stopped at an arbitrary rotation position. As described above, the sun visor main body 1 is formed by covering a frame or base material such as plastic with an impact absorbing material such as foamed plastic, or further covering it with an exterior material such as a plastic sheet. The structure is the same as that of a known visor.

  As is well known, the entire guide bar 3 can be configured to be able to swing horizontally. In such a structure, the sun visor body 1 is swung not only on the windshield but also on the side window side. The sun visor body 1 can be used as a side window awning. For example, in the case of the illustrated sun visor body 1, the left end instead of the right end of the guide bar 3 is used as a swing support portion, and the sun visor body 1 can be swung to the left side window side. In the following, the case where the sun visor body 1 is used for the windshield will be described for ease of explanation. However, whether the sun visor body 1 is used in the side window or the windshield does not have a great influence on the present invention. .

  The guide bar 3 is arranged outside the vehicle windshield and along the boundary between the windshield and the roof. When the sun visor body 1 is rotated to the accommodation position (position A) as shown in FIG. The visor body 1 does not hide the windshield. Hereinafter, the surface facing the vehicle occupant at the A position is referred to as an A surface for convenience. On the other hand, when the sun visor body 1 is rotated in the direction B as shown in FIG. 2 or FIG. 3, the surface opposite to the surface A shown in FIG. Hereinafter, this surface is referred to as B surface for convenience.

  The B position in FIGS. 2 and 3 is a view seen from the direction of the occupant's line of sight when in the B position. When the sun or other light is bright or the built-in mirror is to be used, the sun visor body Move 1 to position B.

  A mirror 7 covered with a lid 6 is provided on the B surface shown in FIGS. The mirror 7 is provided as a so-called makeup mirror (vanity mirror), and the mirror 7 can be hidden by closing the lid 6. Here, the swingable lid 6 using a plastic sheet hinge or the like is illustrated, but the lid 6 may of course have a sliding structure. The lid 6 is not necessarily provided, but it is preferable to provide the lid 6 containing a buffer material or the like so as to cover the mirror 7 made of a material such as glass. By providing the lid 6, the mirror 7 can be protected from dust and dirt.

  FIG. 3 shows the B surface of the sun visor main body 1 in a state where the knob 6a of the lid 6 is operated and the lid 6 is opened. The lid 6 can be fixed to a closed position (FIG. 2) or an open position using a magnet latch, Velcro tape, or the like. In this state, the occupant can use the mirror 7 for an application such as a makeup mirror. In this embodiment, a light emitting portion 8 is provided around the mirror 7 so that the mirror 7 can be used even in a low illumination state such as at night. Yes.

  The light emitting unit 8 is made of, for example, a plastic material such as milky white or transparent acrylic, and can irradiate the illumination light of the LED illumination element (the following LED 11) inside the sun visor body 1 toward the interior of the vehicle.

  FIG. 4 shows a cross-sectional structure of the inside of the sun visor body 1 with the B surface (FIGS. 2 and 3) taken upward in the figure. In FIG. 4, reference numeral 11 denotes an LED as an illumination light source. The LED 11 irradiates illumination light to the side edge of the light guide plate 2, and the light guide plate 2 further functions as a light guide and is disposed around the mirror 7. Transmits illumination light to

  Therefore, if the lid 6 is opened as shown in the figure at the B position of the sun visor body 1 (FIG. 3), the illumination light of the LED illumination is emitted toward the interior of the vehicle.

  The light guide plate 2 is made of a plastic material such as milky white or transparent acrylic, and light incident from the side surface is diffusely reflected inside the light guide plate to emit light. Therefore, by exposing the light guide plate 2 to the surface A of the sun visor body 1 as shown in FIG. 1, brighter illumination light can be emitted toward the interior of the vehicle.

  The area of the light guide plate 2 is slightly larger than that of the mirror 7, and the light guide plate 2 makes illumination light incident on the light emitting portion 8 arranged at the peripheral portion not blocked by the mirror 7. The amount of illumination light is weaker than the amount of light irradiated from the A side (FIG. 1) side of the light guide plate 2, and even when LED illumination is used together with the mirror 7, the occupant is not dazzling and is not dazzled. In applications such as makeup retouching, the occupant's face is illuminated from the periphery of the mirror 7 in the same way as so-called ring illumination, so that the mirror 7 can be easily seen and reflected even in low illumination levels that do not dazzle the occupant. Can be formed.

  The LED 11 may be wired to a wire harness connected to a vehicle-mounted battery via an ON / OFF switch or the like. However, as described above, wiring to the swinging sun visor body 1 is performed. There is a problem that the configuration is complicated and the assembly is complicated.

  Therefore, in the present embodiment, a configuration in which the LED 11 is driven by the battery 10 and the battery 10 can be charged by the solar cell 9 is shown.

  A switch 5 is inserted in the wiring between the battery 10 and the LED 11, and the on / off of the LED 11 can be controlled by the switch 5.

  In the structure in which the light guide plate 2 is exposed on the surface A of the sun visor body 1 as shown in FIG. 1, the angle of the light emitting surface of the light guide plate 2 can be adjusted by swinging the sun visor body 1. The light emitting surface can be used as a room lamp. Considering this application, the switch 5 is provided on the A side as shown in FIG. 1. However, the switch 5 is provided only on the B side, or on both the A and B sides. Wiring may be performed so that the switch 5 can be turned on / off.

  The switch 5 may be controlled to be turned on / off in conjunction with a lid 6 or a sensor (such as a limit switch) (not shown) that detects the attitude of the sun visor body 1. Thereby, for example, the LED 11 is automatically turned on when the lid 6 is opened, and the LED 11 is automatically turned on when the sun visor body 1 is swung to the position B in FIGS. 2 and 3. The LED lighting element can be automatically turned on or off without troublesome operations. At that time, control is performed such that the ambient brightness is detected by using an optical sensor or the like at the same time or detecting the output of a solar cell 9 described later, and the LED 11 is automatically turned on only when the surrounding is dark. It may be performed simultaneously.

  The battery 10, the switch 5, and the LED 11 constitute an illumination and power supply unit 4 whose position is indicated by the same reference numeral 4 in FIGS. 1 to 3.

  In this embodiment, the battery 10 is configured to be charged by the solar cell 9 via a charging circuit (not shown). For example, the charging circuit may include a circuit that controls the charging current so that the battery 10 is not overcharged, or may be provided with a control circuit that detects ambient brightness and switches between charging and light emission.

  As shown in FIG. 2 (FIG. 3), when the sun visor main body 1 is lowered to the B position and the sun visor main body 1 is used as a sunshade, the light guide plate 2 faces the windshield. Some percentage of the external light incident on the light guide plate 2 via the light guide plate 2 reaches the solar cell 9, and the battery 10 is charged by the electromotive force of the solar cell 9.

  In addition, even when the sun visor body 1 is housed as shown in FIG. 1 (position A), the charging efficiency is lower than in the position B, but the battery 10 is charged by the generated power of the solar cell 9 by reflected light in the room. Is done.

  In this way, when the sun visor body 1 is used as an awning, the sun visor body 1 can be used only as an original awning by providing the light receiving surface (light guide plate 2) of the solar cell 9 on the A surface facing the outside. The battery 10 can be efficiently charged, and when the mirror 7 is used at night, the light emitting portion 8 can emit light (FIG. 3), and the light guide plate 2 can emit light as indoor auxiliary lighting.

  Further, the LED 11 can be driven with low power consumption, and even the battery 10 charged with the solar cell 9 generates a sufficient amount of light from the light emitting portion 8 around the mirror 7 or the light emitting surface of the light guide plate 2 as a surface emitting illumination device. be able to.

  Furthermore, since the LED 11 is driven by the battery 10 and not by the in-vehicle battery, no wiring is required from the in-vehicle battery to the wire harness in the vehicle, and the sun visor device can be easily assembled at low cost. Further, since the battery 10 is charged by the solar battery 9, there is no need for troublesome work such as battery replacement, and there is no need for a configuration in which the wiring is passed through the swinging mechanism. Does not occur.

  In addition, as described above, the light emitting unit 8 illuminates the face from the front unlike the conventional interior light when using the mirror 7 at night. Since the illumination light is emitted in the same posture as the mirror 7, the shadow does not stand out and is just suitable for retouching.

  As described above, the sun visor device of the present embodiment can use the light guide plate 2 as a surface emitting interior light by turning on the LED 11 at the A position (FIG. 1), and at the B position (FIG. 2), In the daytime, it can be used as a normal sun visor, and at this time, the battery 10 can be charged with electric power generated in the solar cell 9 by external light incident through the light guide plate 2 facing the windshield at the same time. . Further, at night, when the mirror 6 is used with the lid 6 opened as shown in FIG. 3, the light-emitting portion 8 around the mirror 7 can emit light gently. At this time, ideal illumination from the direction and front of the mirror 7 can be obtained. In particular, since the light emitting unit 8 illuminates the occupant's face from the periphery of the mirror 7 in an illumination manner close to ring illumination, it is not dazzling, and can sufficiently illuminate the occupant's face even in low light amounts, for example, for retouching.

  In the above embodiment, the light guide plate 2 is provided on the surface A (FIG. 1), and the solar cell 9 is disposed on the inner side of the light guide plate 2 (FIG. 4). However, if it is not necessary to use the light guide plate 2 for room illumination, the light guide plate 2 is not necessarily provided to be exposed on the A surface (FIG. 1), and the positional relationship between the light guide plate 2 and the solar cell 9 in FIG. The light receiving surface of the solar cell 9 may be exposed to the A surface of the sun visor body 1 so that the light of the light guide plate 2 does not leak from the A surface side.

  The configuration of the present invention can be implemented in various vehicle sun visor devices with mirrors or lighting devices.
