Description

  The present invention relates to a vehicle door mirror and a lamp and a lens cover in the vehicle door mirror.

  For example, when a direction indicator lamp is mounted on the vehicle door mirror, if a gap is formed between the housing cover of the vehicle door mirror and the lamp, the gap communicating with the inside and outside of the housing during the traveling of the vehicle May pass through and make a sound. For example, when a lamp is embedded and mounted so as to be exposed from the convex curved surface of the housing cover, the air hitting the convex curved surface of the housing cover flows backward at high speed, and at this time, the vicinity of the lamp becomes negative pressure due to the high-speed flow of air. There is a problem that air is sucked out from the inside of the housing cover to the outside on the negative pressure side, and a so-called sucking sound is generated. Conventionally, in order to prevent this noise, the gap between the housing cover and the lamp has been closed with an elastic pad. However, it is necessary to prepare a separate pad and attach it to the housing cover or the lamp, which is very troublesome. It involved a lot of work.

  An object of the present invention is to provide a vehicle door mirror and a lamp and a lens cover in the vehicle door mirror that prevent the generation of sound while reducing the number of parts and the manufacturing process.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the lens cover in the vehicle door mirror of the present invention is:
A convex-curved housing cover constituting the outer surface, and a lamp including a translucent lens cover that is attached to a part of the housing cover and has a lens function of covering the light source from the outside and projecting the light to the outside , A lens cover for a vehicle door mirror comprising:
In the housing cover, a notch for communicating the inside and outside of the housing cover for mounting the lens cover corresponding to the outline of the lens cover is formed with a closed outline or a partially opened outline, A part of itself is exposed to the outside from the notch, the other part is hidden behind the housing cover, and is fixed to face the back of the housing cover with a gap allowing air flow,
In the lens cover region facing the back surface of the housing cover, irregularities are formed to make the flow of air flowing inside and outside the notch through the gap with the housing cover unrectified.

  According to the present invention, since the lens cover is fixed so as to face the back surface of the housing cover with a clearance allowing air flow, air flows in the region of the lens cover facing the back surface of the housing cover. A space is formed. By forming irregularities on the lens cover in this region, sucking sounds and other sounds that are anxious during vehicle travel are eliminated or reduced. The reason is not out of the speculation area, but when the airflow passes smoothly through the gap, it tends to sound like a whistle, whereas for example, the lens cover area facing the back of the housing cover has irregularities. If formed, the flow of air flowing inside and outside the notch through the gap between the lens cover and the housing cover becomes unrectified, so the frequency of air changes and the generation of sound cannot be prevented or suppressed. (However, it does not limit or dictate the sound prevention mechanism). On the other hand, since the gaps through which air flows are not blocked, pad manufacture and sticking become unnecessary, leading to cost reduction.

Moreover, in order to solve the said subject, the lamp for the vehicle door mirror of this invention is the following.
A convex-curved housing cover constituting the outer surface, and a lamp including a translucent lens cover that is attached to a part of the housing cover and has a lens function of covering the light source from the outside and projecting the light to the outside , A lamp in a vehicle door mirror comprising:
In the housing cover, a notch for communicating the inside and outside of the housing cover for mounting the lens cover corresponding to the outline of the lens cover is formed with a closed outline or a partially opened outline, A part of itself is exposed to the outside from the notch, the other part is hidden behind the housing cover, and is fixed to face the back of the housing cover with a gap allowing air flow,
In the lens cover region facing the back surface of the housing cover, irregularities are formed to make the flow of air flowing inside and outside the notch through the gap with the housing cover unrectified.

  The present invention is configured as a lamp including a lens cover and a light source (the above-described invention is configured as a lens cover in the lamp), and is generated in a vehicle door mirror during traveling, similar to the above-described lens cover invention. The problem of easy sound can be improved.

Furthermore, in order to solve the said subject, the door mirror for vehicles of this invention is the following.
A convex-curved housing cover constituting the outer surface, and a lamp including a translucent lens cover that is attached to a part of the housing cover and has a lens function of covering the light source from the outside and projecting the light to the outside A vehicle door mirror comprising:
In the housing cover, a notch for communicating the inside and outside of the housing cover for mounting the lens cover corresponding to the outline of the lens cover is formed with a closed outline or a partially opened outline, A part of itself is exposed to the outside from the notch, the other part is hidden behind the housing cover, and is fixed to face the back of the housing cover with a gap allowing air flow,
In at least one of the lens cover region facing the back surface of the housing cover and the back surface of the housing cover, the flow of air flowing inside and outside the notch through the gap between the back surface of the housing cover and the lens cover is non-rectified. Unevenness is formed.

  The present invention is configured as a vehicle door mirror in which a lamp is incorporated, and is different from the lens cover and the lamp invention described above in that at least a lens cover region corresponding to the rear surface of the housing cover and the lens cover are provided. Concavities and convexities are formed on one side. That is, it includes three modes in which irregularities are formed only on the lens cover, irregularities are formed only on the housing cover, and irregularities are formed on both the lens cover and the housing cover. In any of these three modes, the flow of air flowing inside and outside the notch through the gap between the lens cover and the housing cover is derectified, and the problem of sound is improved.

  The unevenness includes the plurality of dimples formed on the outer surface of the lens cover and the outer surface of the lens cover separating the plurality of dimples, or the plurality of dimples formed on both the lens cover and the housing cover and the plurality of dimples. It can be formed by a surface formed and separating the plurality of dimples. In the case of dimples, irregularities can be formed by recesses, so for example, a plurality of convex portions for adding dimples to the injection mold may be added to a resin lens cover or housing cover. The number of parts of the housing cover does not increase and the manufacturing process is easy.

  As shown in FIG. 4, the reflector 9 is disposed on the back side of the lens cover 3, and the surface 9 b side (lens cover 3 side) of the reflector 9 serves as a reflection surface and has an opening 9 a that guides light from the light source unit 10.

  The light source unit 10 includes a substrate 10a disposed along the longitudinal direction of the lens cover 3 on the back surface side (base member 11 side) of the reflector 9, and a light source (light emitter) 10b that supplies light from the substrate 10a. Have. The light source 10 b emits light from the opening 9 a of the reflector 9 toward the lens cover 3. Since the surface 9 b of the reflector 9 is a reflecting surface, the reflected light reflected by the reflecting surface is also taken out from the lens cover 3.

  The base member 11 is a structure inside the lamp 2 having a longitudinal shape, and is attached to the housing main body 7 with the outer lens cover 3 fixed integrally.

  FIG. 5 shows an AA cross-sectional view of the vehicle door mirror 2 of FIG. 1, and FIG. 6 is a partially enlarged view of the cross-sectional view of FIG. The gap 13 formed by the outer surface 3c of the lens cover 3 and the rear surface 4a of the housing cover 4 will be described with reference to FIGS.

  As shown in FIG. 5, which is a sectional view of the vehicle door mirror 1, a part of the lens cover 3 is exposed to the outside from the notch 8 of the housing cover 4. On the other hand, the other part of the lens cover 3 is fixed to the housing body 7 so as to be hidden behind the housing cover 4 and to face the back surface 4a of the housing cover 4 with a gap 13 allowing air flow. .

  Specifically, as shown in a partially enlarged view of the housing cover 4 and the lamp 2 in FIG. 6, the central portion 3 a of the lens cover 3 protrudes from the notch 8 of the housing cover 4, and the lens along the inner edge 8 a of the notch 8. The center portion 3a of the cover 3 is surrounded, and the rear surface 4a of the housing cover 4 including the notch 8 of the housing cover 4 and the inner edge 8a of the notch 8 and the outer peripheral portion 3b of the lens cover 3 of the lamp 2 are arranged to face each other. The housing cover 4 and the lamp 2 are individually attached to the housing body 7. As a result, a gap 13 is formed in the region of the lens cover 3 facing the back surface 4a of the housing cover 4 through which the air flows between the inside and the outside of the vehicle door mirror 1 through the notch 8 of the housing cover 4. .

  The gap 13 is formed with the dimples 12 constituting the above-described irregularities for non-rectifying the flow of air flowing through the gap 13. FIG. 7A shows a cross-sectional view of the plurality of dimples 12 forming the unevenness and the outer surface 3 c of the lens cover 3. As shown in FIG. 7A, the unevenness is formed by a plurality of dimples 12 and an outer surface 3 c of the lens cover 3 that separates the plurality of dimples 12. In the enlarged cross-sectional view of FIG. 6, the number of the dimples 12 is five. However, the number is not limited to five, and may be any number as long as the flow of air passing through the gap 13 is non-rectified.

  With the above-described configuration, the vehicular door mirror 1 according to this embodiment adds the shape of the dimple 12 to the outer surface 3 c of the lens cover 3 that forms the gap 13. Therefore, when air passes through the gap 13, the generation of sound or the like can be prevented by making the air flow unrectified by the dimples 12 formed on the surface of the outer peripheral portion 3 b of the lens cover 3.

  Here, FIG. 8 is a reference view showing the conventional vehicle door mirror 1 in which the gap 13 is closed by the pad 14 in the partially enlarged view of FIG. FIG. 8 shows that the air flowing from the inside of the vehicle door mirror 1 to the outside and the air flowing from the outside to the inside of the vehicle door mirror 1 are blocked by the pad 14 during traveling of the vehicle. In order to form, the pad 14 is provided in the outer peripheral part 3b of the lens cover 3, and it is not necessary to stick the pad 14 to the lens cover 3, and a number of parts and a manufacturing process can be reduced.

  Next, a modified example of the vehicle door mirror 1 and the lamp 2 and the lens cover 3 in the vehicle door mirror 1 of the present invention will be described with reference to FIG. The same configurations as those of the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the embodiment shown in FIG. 6, in the gap 13 formed by the lens cover 3 (interior body 6) and the housing cover 4, a plurality of dimples 12 are arranged separated by the outer surface 3 c of the lens cover 3 to form irregularities. The air passing through the gap 13 is non-rectified.

  In FIG. 9A, which is Modification 1, a plurality of protrusions 15 are formed on the lens cover 3 instead of the dimples 12. FIG. 7B shows a cross-sectional view of the outer surface 3 c of the lens cover 3 in which irregularities are formed by the protrusions 15. As shown in FIG. 7B, the unevenness is formed by a plurality of protrusions 15 and an outer surface 3c of the lens cover 3c that separates the plurality of protrusions 15. By forming the protrusions 15 in the gap 13, the air flow path can be narrowed and the air passing through the gap 13 can be non-rectified.

  In FIG. 9B, which is the second modification, a plurality of dimples 12 are formed only on the housing cover 4, and the air passing through the gap 13 is non-rectified. When air flows from the inside to the outside of the vehicle door mirror 1, not only the outer surface 3 c of the lens cover 3 but also the back surface 4 a of the housing cover 4 serves as an airflow guide portion. It is possible to prevent the generation of a sound when air flows from the inside to the outside, that is, a so-called suction sound.

  In FIG. 9C, which is Modification Example 3, a plurality of protrusions 15 are formed on the lens cover 3 and the housing cover 4, and irregularities are formed on both the lens cover 3 and the housing cover 4. Specifically, the protrusions 15 are formed at regular intervals on the back surface 4 a of the housing cover 4, and the projections 15 are also formed at regular intervals on the outer surface 3 c of the lens cover 3. In the gap 13 formed by the outer surface 3 c of the lens cover 3 and the rear surface 4 a of the housing cover 4, the outer surface 3 c of the lens cover 3 that faces the protrusion 15 on the rear surface 4 a of the housing cover 4 becomes a recess, and the outer surface 3 c of the lens cover 3. The protrusion 15 is formed so that the back surface 4a of the housing cover 4 facing the protrusion 15 also becomes a recess.

  Therefore, air collides with the projection 15 on the back surface 4a of the housing cover 4 or the outer surface 3c of the lens cover 3, and the other concave portion (if the air collides with the projection 15 of the housing cover 4, it becomes a concave portion of the lens cover 3, When air collides with the protrusion 15 of the cover 3, the air is guided to the concave portion of the housing cover 4. As a result, it is possible to inhibit the flow of air and make the air non-rectified.

  In FIG. 9D, which is the fourth modification, the outer surface 3c of the lens cover 3 and the rear surface 4a of the housing cover 4 of the third modification (FIG. 9C) are configured with wavy curved surfaces. With this curved surface, the airflow passing through the gap 13 can meander, and the air can be non-rectified.

  In FIG. 9E, which is the modified example 5, the protrusion 15 on the back surface 4a of the housing cover 4 of the previous modified example 3 (FIG. 9C) and the protrusion 15 on the outer surface 3c of the lens cover 3 are opposed to each other. It is arranged. Since the flow rate at which air can flow is changed in the middle of the gap 13 by the projections 15, the flow rate of the airflow can be varied to prevent a smooth flow of the airflow, and the airflow can be non-rectified.

  In FIG. 9 (f), which is a modified example 6, the outer surface 3 c of the lens cover 3 and the back surface 4 a of the housing cover 4 of the previous modified example 5 (FIG. 9 (e)) are configured with wavy curved surfaces. By this curved surface, air can be retained in the recess, and the flow of air can be non-rectified.

  In FIG. 9 (g), which is the modified example 7, the projection 15 of the previous modified example 5 (FIG. 9 (e)) is formed as the dimple 12, and the air is retained in the dimple 12 so that the air flow is reduced. Can be non-rectified.

  The shapes of the dimples 12 and the protrusions 15 are not limited to the hemispherical dimples 12 and the protrusions 15 as shown in FIG. 10, but are pyramids, prisms, pyramids, prisms, cones, cylinders, The dimple 12 or the protrusion 15 may be used. 1 to 10, the notch 8 of the housing cover 4 is formed with a substantially U-shaped contour that is partially opened. However, as shown in FIG. 11, a substantially elliptical contour with the notch 8 closed. May be formed.

  Further, in the above-described embodiment or modification, even when air flows from the outside to the inside of the vehicle door mirror 1, the airflow flows through the back surface 4 a of the housing cover 4 and the outer surface 3 c of the lens cover 3. Therefore, it is possible to prevent noise when air flows from the outside to the inside of the vehicle door mirror 1.

  As mentioned above, although the Example and modification of this invention were demonstrated, this is only an illustration to the last, and this invention is not limited to this, Unless it deviates from the meaning of a claim, Example and Various modifications based on the knowledge of those skilled in the art, such as combining modified examples, are possible.
