The substrate unit 52 is sealed (against water and the like) by being sealed inside the case 48 as described above. An operation mechanism 56 is integrally provided to a substrate 54 in the substrate unit 52. Electrical power is supplied to the substrate unit 52, and the operation mechanism 56 is operated under control from the substrate 54. The operation mechanism 56 is configured, for example, by a light emitting device (light device) or light receiving device (light detector device, camera), and is capable of emitting light or receiving light through a transparent section, facing towards the inside the case 48, of the mirror 46.
Explanation follows regarding operation of the present exemplary embodiment.
In the vehicle door mirror device 10 configured as explained above, when the mirror face adjustment device 32 is driven, the tilt plate 36 tilts with respect to the fixing section 34, thereby tilting the mirror body 38 integrally to the tilt plate 36, and accordingly adjusting the angle of the mirror face 46A of the mirror 46.
When the mirror body 38 is tilted, the press contact face 44A of the press contact tab 44 that is integrated to the holder 40 slides against the anti-vibration portion 30A of the anti-vibration pillar 30 that is integrated to the visor body 24, with press contact of the press contact tab 44 (the press contact face 44A) to the anti-vibration pillar 30 (the anti-vibration portion 30A) being maintained.
The case 48 is disposed at the back face side of the mirror 46, and the substrate unit 52 is accommodated in the case 48, a portion between the mirror 46 and the case 48 is sealed with the sealing agent 50, the inside of the case 48 is sealed, accordingly, the substrate unit 52 is sealed. The substrate unit 52 is thereby sealed using a simple configuration, and hence a reduction in cost and reduction in weight is achieved.
There is relatively large weight at a position, corresponding to the substrate unit 52, of the mirror body 38, and so vibration is readily induced in the mirror body 38 due to the weight of the substrate unit 52.
Here, the sealing agent 50 bonds the holder 40 (including the housing box 42) and the case 48, integrating together the holder 40, the case 48 and the sealing agent 50. The press contact tab 44 is also integrally provide to the housing box 42 (a portion integrated to the sealing agent 50), and the press contact tab 44 is in press contact with the anti-vibration pillar 30 of the visor body 24. The support rigidity to the mirror 46 at the position of the substrate unit 52 can accordingly be efficiently raised, vibration of the mirror 46 due to the substrate unit 52 can be efficiently suppressed, and chatter of the mirror face 46A of the mirror 46 can be efficiently suppressed. Accordingly, not only can a reduction in visibility with the mirror 46 during vehicle travel be efficiently suppressed, but it is also possible to achieve a reduction in weight of the anti-vibration pillar 30 and the press contact tab 44, and possible to eliminate a requirement to provide another vibration suppressing member.
Furthermore, the case 48 and the sealing agent 50 are bonded to the mirror 46, and the mirror 46, the case 48 and the sealing agent 50 are integrated together. The support rigidity of the mirror 46 at the position of the substrate unit 52 can accordingly be even more efficiently raised, vibration of the mirror 46 due to the substrate unit 52 can be even more efficiently suppressed, and chatter of the mirror face 46A of the mirror 46 can be even more efficiently suppressed.
Further, due to the vehicle rear-side end faces of the case 48 and the sealing agent 50 fitting (joining) to the back face of the mirror 46, the mirror 46 can be strongly integrated to the case 48 and the sealing agent 50. The support rigidity of the mirror 46 at the position of the substrate unit 52 can accordingly be even more efficiently raised, vibration of the mirror 46 due to the substrate unit 52 can be even more efficiently suppressed, and chatter of the mirror face 46A of the mirror 46 can be even more efficiently suppressed.
Furthermore, the substrate unit 52 is covered by the case 48 and the case 48 is covered by the sealing agent 50 and the sealing agent 50 is covered by the housing box 42. Accordingly, a portion of the mirror body 38, corresponding to the case 48, the sealing agent 50 and the housing box 42, is configured with a large cross-sectional area perpendicular to the direction from the mirror 46 towards the press contact tab 44 (the vehicle front-rear direction), raising rigidity. The support rigidity of the mirror 46 at the position of the substrate unit 52 can accordingly be even more efficiently raised, vibration of the mirror 46 due to the substrate unit 52 can be even more efficiently suppressed, and chatter of the mirror face 46A of the mirror 46 can be even more efficiently suppressed.
In the present exemplary embodiment, the press contact tab 44 is integrally provided to the housing box 42 of the holder 40, however configuration may be made such that the press contact tab 44 is integrally provided to a portion, integrated to the sealing agent 50, of the holder 40 (at which portion is integrated to the sealing agent 50) and/or integrally provided to the sealing agent 50 (the case 48) (FIGS. 4 and 5).
In the present exemplary embodiment the anti-vibration pillar 30 is integrally provided to the visor body 24, however configuration may be made such that the anti-vibration pillar 30 is integrally provided to the mirror face adjustment device 32 at the peripheral wall of the fixing section 34.
Second Exemplary Embodiment
FIG. 3 illustrates a cross-section of main portions of a vehicle door mirror device 70 according to a second exemplary embodiment.
The vehicle door mirror device 70 according to the second exemplary embodiment is of substantially the same configuration as that of the first exemplary embodiment, however it differs in the following aspects.
The anti-vibration pillar 30, the housing box 42 and the press contact tab 44 of the first exemplary embodiment are not provided in the vehicle door mirror device 70 according to the second exemplary embodiment.
In a mirror body 38, a placement hole 72 is formed so as to pass through a vehicle width direction outside portion of the holder 40. A case 48 is disposed so as to pass through the placement hole 72.
Sealing agent 50 between the holder 40, a mirror 46 and the case 48 is filled (applied) in the entire of gap between the holder 40 and the mirror 46 around the entire periphery of the case 48, and filled in the entire of gap between the entire periphery of the placement hole 72 of the holder 40 and the case 48, and filled in the vehicle front-side of the holder 40 around the entire periphery of the case 48. The sealing agent 50 is hardened (cured). The sealing agent 50 is bonded (adhered) and fitted (joined) to the holder 40, the mirror 46 and the case 48, and the sealing agent 50 is integrated to the holder 40, the mirror 46 and the case 48. The sealing agent 50 covers and seals between the mirror 46 and the entire periphery of the case 48, thereby sealing the inside of the case 48.
A tilt plate 36 (vehicle body side) of the mirror face adjustment device 32 is increased in size relative to the first exemplary embodiment, and approaches the sealing agent 50 (contact may be made with the sealing agent 50), and the tilt plate 36 is integrally overlapped (or polymerized) with a portion of the holder 40, that is integrated to the sealing agent 50 (at which portion is integrated to the sealing agent 50).
As described above, the tilt plate 36 is integrally overlapped with the portion of the holder 40 that is integrated to the sealing agent 50. The support rigidity to the mirror 46 at the position of the substrate unit 52 can accordingly be raised, vibration of the mirror 46 due to the substrate unit 52 can be suppressed, and chatter of the mirror face 46A of the mirror 46 can be suppressed.
Furthermore, the case 48 and the sealing agent 50 are adhered to the mirror 46, integrating the mirror 46 to the case 48 and the sealing agent 50. The support rigidity to the mirror 46 at the position of the substrate unit 52 can accordingly be raised well, vibration of the mirror 46 due to the substrate unit 52 can be suppressed well, and chatter of the mirror face 46A of the mirror 46 can be suppressed well.
However, due to the vehicle rear-side end faces of the case 48 and the sealing agent 50 fitting (joining) to the back face of the mirror 46, the mirror 46, the case 48 and the sealing agent 50 can be strongly integrated together. The support rigidity of the mirror 46 at the position of the substrate unit 52 can accordingly be even better raised, vibration of the mirror 46 due to the substrate unit 52 can be even better suppressed, and chatter of the mirror face 46A of the mirror 46 can be even better suppressed.
Whereas in the first exemplary embodiment and the second exemplary embodiment the mirror 46 is configured with a flat plane profile, the mirror 46 may be configured such that the back face of the mirror 46 is curved in a curved plate profile mirror 46. In such cases, the mirror 46 and the case 48 can be as strongly integrated together by curving the vehicle rear-side end face of the case 48 so as to follow the back face of the mirror 46, and fitting (joining) the case 48 to the back face of the mirror 46.
Whereas in the first exemplary embodiment and the second exemplary embodiment the vehicle mirror device of the present invention is applied to the vehicle door mirror device 10 or 70, the vehicle mirror device of the present invention may also be applied to another external vehicle mirror device (such as a vehicle fender mirror device) outside a vehicle, or to an internal vehicle mirror device inside a vehicle.
