Description

The present invention relates to a door mirror installed on a vehicle door.

In the door mirror of a vehicle, the door mirror body including the mirror body is attached to the door via a metal mirror base. A support shaft that rotatably supports the door mirror body in a substantially horizontal direction is attached to the mirror base. Further, the portion protruding outward from the door of the mirror base is covered with a resin base cover that covers the outside of the mirror base. The base cover has an opening in which the support shaft protrudes upward, and the door mirror main body is rotatably attached to a support shaft portion protruding upward from the base cover.

Since this type of door mirror has a structure in which the door mirror body rotates with respect to the mirror base and the base cover, there is a gap between the base cover and the door mirror body to allow relative rotation between the two. It is set. However, if the running wind enters the gap while the vehicle is running, it tends to cause a wind noise. As a countermeasure against this, a door mirror has been devised in which the above gap is filled with a sealing member (see, for example, Patent Document 1).

In this door mirror, a seal member is attached to the upper surface of the peripheral region at the protruding position of the support shaft of the base cover, and the seal member is slidably in contact with the lower surface of the door mirror body. In this door mirror, since the gap between the base cover and the door mirror main body is filled with the annular seal member, it is possible to suppress the generation of wind noise during traveling.

JP-A-2018-394403

In the conventional door mirror, when the door mirror main body is rotated, the door mirror main body is displaced in the rotational direction while the seal member is in contact with the lower surface of the door mirror main body. For this reason, when the contact resistance between the door mirror body and the seal member is partially increased for some reason, there is a concern that the seal member may be twisted by the operation of the door mirror body, causing lifting or misalignment. To.

Therefore, the present invention is intended to provide a door mirror capable of stably obtaining the effect of preventing the generation of wind noise by the seal member for a long period of time.

In order to solve the above problems, the door mirror according to the present invention has the following configuration.
That is, the door mirror according to the present invention includes a door mirror main body including a mirror body, a support shaft that rotatably supports the door mirror main body in a substantially horizontal direction, the support shaft, and the support shaft and the door mirror main body. In a mirror base that connects the mirror base to the door of the vehicle, a base cover that surrounds a portion of the mirror base located outside the door, and has an opening in which the support shaft protrudes, and a peripheral edge of the opening. A seal member for closing the gap between the base cover and the door mirror main body is provided, and the seal member has a fixed portion sandwiched between the mirror base and the base cover and the inside of the opening. It is characterized by having an annular seal portion that extends from the fixed portion to the door mirror main body side and slidably abuts on the door mirror main body.

The fixed portion may be configured to be connected to the annular seal portion and have an annular seal base portion that is in close contact with the peripheral region of the opening of the base cover.

The mirror base has an annular boss portion whose end surface abuts on the seal base portion, and the fixed portion has an engaging piece that projects from the seal base portion and abuts on the outer peripheral surface of the boss portion. It may be configured.

An even number of the engaging pieces may be projected in the circumferential direction of the seal base, and the pair may be arranged at positions facing each other in the radial direction of the seal base.

The base cover may have a locking projection protruding toward the seal member side, and any of the engaging pieces may have a protrusion receiving portion into which the locking projection is fitted.

The protrusion receiving portion may be configured by a through hole penetrating the engaging piece, and the boss portion may have a recess into which the tip end portion of the locking protrusion penetrating the through hole is fitted.

The seal base has an annular protrusion formed along the circumferential direction of the seal base at a position separated from the annular seal portion, and the base cover is a surface of the annular protrusion on the door mirror body side and the surface of the seal base. It may be configured to have a displacement regulating portion that abuts on the radial outer surface of the annular protrusion.

In the present invention, since the fixed portion of the seal member is sandwiched between the rigid mirror base and the base cover, the seal member is lifted even if an external force is applied to the annular seal portion due to the rotation of the door mirror body. And misalignment can be suppressed. Therefore, when the present invention is adopted, the effect of preventing the generation of wind noise by the seal member can be stably obtained for a long period of time.

The seal base portion 40a is in close contact with the base cover 14 in an annular shape with the peripheral edge portion (step portion 48 described in detail later) on the lower surface side of the opening portion 8. Further, the annular seal portion 40c extends toward the door mirror main body 12 side through the inside of the opening 8 of the base cover 14 (the area surrounded by the peripheral edge of the opening 8) in the state of being assembled to the door mirror 10. In the peripheral region of the support shaft 35, it slidably abuts on the lower surface of the mirror housing 15.
In the present embodiment, the annular seal base 40a and the plurality of engaging pieces 40b form a fixed portion to be sandwiched and fixed between the mirror base 13 and the base cover 14.

In the case of the present embodiment, six engaging pieces 40b are projected on the outer periphery of the seal base 40a. The six engaging pieces 40b are not arranged at equal intervals on the outer periphery of the seal base 40a, but the paired pieces are arranged at positions facing each other in the radial direction of the seal base 40a.
The six engaging pieces 40b are arranged so as to be point-symmetrical on the circumference of the seal base 40a. Further, the six engaging pieces 40b are arranged so as to be line-symmetric with respect to a specific straight line S passing in the radial direction of the seal base portion 40a. Reference numeral o2 in FIG. 6 is a central axis of the annular seal base portion 40a. Therefore, if the seal members 40 can be assembled so that both sides of the specific straight line S are aligned with the left and right sides of the vehicle, the symmetrically shaped left and right door mirrors 10 use the seal members 40 having the same specifications as they are. be able to. That is, in the door mirrors 10 on the left and right sides of the vehicle, interference between each engaging piece 40b of the seal member 40 and the surrounding members can be similarly avoided.

Further, at the upper end of the outer peripheral surface of the boss portion 9 of the mirror base 13, an inclined surface 13a inclined downward in the radial direction is formed in an annular shape over the outer periphery of the boss portion 9.
As shown in FIGS. 7 and 8, each engaging piece 40b of the sealing member 40 is formed to have a substantially triangular (wedge-shaped) cross-sectional shape in the radial direction. Specifically, the engaging piece 40b has a flat upper surface 40 bu and an inclined lower surface 40 bl that inclines downward from the inside in the radial direction to the outside, and the vertical width between the upper surface 40 bu and the inclined lower surface 40 bl is radially inside. It gradually increases from to the outside. Each engaging piece 40b regulates the radial positional deviation of the seal member 40 with respect to the boss portion 9 by abutting (engaging) the inclined lower surface 40bl with the inclined surface 13a of the boss portion 9.

Further, of the six engaging pieces 40b of the seal member 40, one engaging piece 40b located inside in the vehicle width direction and one engaged piece 40b located outside in the vehicle width direction when the door mirror 10 is attached to the vehicle, etc. A through hole 42 that penetrates the engaging piece 40b in the vertical direction is formed in one of the engaging pieces 40b. The through hole 42 is formed in a pair of engaging pieces 40b arranged at positions facing each other in the radial direction of the seal base portion 40a. A part of each through hole 42 is formed so as to straddle the annular seal portion 40c.

In the present embodiment, the through hole 42 constitutes the protrusion receiving portion. Each through hole 42 is fitted with a locking projection 43 of the upper wall 14a-u of the base cover 14 that projects downward (toward the seal member side) from the peripheral edge of the opening 8. That is, two locking projections 43 corresponding to the two through holes 42 on the seal member 40 side are projected from the peripheral edge of the opening 8 of the base cover 14. Each locking projection 43 penetrates the corresponding through hole 42 from above to below.

Two recesses 44 that are recessed downward are formed on the upper surface side of the outer peripheral edge portion of the boss portion 9 of the mirror base 13. The two recesses 44 are formed at positions corresponding to the protruding positions of the two locking projections 43 of the base cover 14. The tip of the locking projection 43 that penetrates the corresponding through hole 42 of the seal member 40 is fitted into each recess 44. As a result, the seal member 40 is positioned in the circumferential direction (around the central axis o2) with respect to the mirror base 13 and the base cover 14.
In the present embodiment, the through hole 42 of the engaging piece 40b constitutes the protrusion receiving portion, but a recess is formed on the upper surface of the engaging piece 40b, and the locking protrusion 43 is fitted into the recess. It may be used as a protrusion receiving part. In this case, the locking projection 43 on the base cover 14 side independently regulates the displacement of the seal member 40 in the circumferential direction.

Further, in the seal member 40, an annular protrusion 47 is formed on the outer peripheral edge of the annular seal base 40a so as to project upward and extend along the circumferential direction of the seal base 40a. The annular protrusion 47 is provided at a position separated by a predetermined distance from the annular seal portion 40c projecting from the inner peripheral edge portion of the seal base portion 40a to the outside in the radial direction of the seal base portion 40a.

On the other hand, an annular step portion 48 that opens to the inner peripheral side and the lower side is formed on the inner peripheral edge portion on the lower surface side of the opening 8 of the base cover 14. An annular protrusion 47 of the seal member 40 arranged on the boss portion 9 of the mirror base 13 is fitted into the step portion 48. The base cover 14 comes into contact with the surface of the annular projection 47 on the door mirror body 12 side and the radial outer surface of the annular projection 47. Specifically, the annular step portion 48 has an inner peripheral wall 48a and an upper bottom wall 48b, and these inner peripheral walls 48a and the upper bottom wall 48b abut on the annular protrusion 47 of the seal member 40. As a result, the seal member 40 is restricted from being displaced in the radial direction and the vertical direction (axial direction) with respect to the base cover 14.
In the present embodiment, the inner peripheral wall 48a and the upper bottom wall 48b of the stepped portion 48 form a displacement regulating portion of the base cover 14.

Further, the annular seal portion 40c of the seal member 40 extends upward from the inner peripheral edge portion of the annular seal base portion 40a with a constant inner and outer diameter, and then extends upward while expanding the diameter outward in the radial direction. Hereinafter, the portion of the annular seal portion 40c that extends upward with a constant inner and outer diameter is referred to as a base region 40c-1, and the portion that extends upward while expanding the diameter outward in the radial direction is referred to as a diameter expansion region 40c-2. Call. The enlarged diameter region 40c-2 of the annular seal portion 40c is formed to be thinner than the base region 40c-1. Further, the diameter-expanded region 40c-2 projects above the upper wall 14a-u of the base cover 14 from the inner region of the opening 8 of the base cover 14 in a state where the seal member 40 is assembled to the door mirror 10. The outer edge of the enlarged diameter region 40c-2 projecting upward from the upper wall 14a-u slidably comes into close contact with the lower surface of the mirror housing 15 of the door mirror body 12.

Next, from this state, the seal member 40 locked to the base cover 14 is aligned with the boss portion 9 of the mirror base 13, and the seal base portion 40a is overlapped with the end surface of the boss portion 9. At this time, the base cover is projected from the seal base 40a so that the inclined lower surface 40bl of the plurality of engaging pieces 40b is brought into contact with the inclined surface 13a on the outer periphery of the boss portion 9, and a part of the engaging pieces 40b is penetrated downward. The lower end of the locking projection 43 on the 14 side is fitted into the corresponding recess 44 on the boss portion 9. In this way, when the inclined lower surface 40bl of the engaging piece 40b comes into contact with the inclined surface 13a of the boss portion 9, the seal member 40 is positioned in the radial direction with respect to the boss portion 9, and the locking projection 43 is fitted into the recess 44. Then, the seal member 40 is positioned in the circumferential direction with respect to the boss portion 9.

After that, when the base cover 14 is fixed to the mirror base 13 by screwing or the like, the upper wall 14a-u of the base cover 14 (upper cover 14U) engages the sealing base 40a of the sealing member 40 with the engaging piece 40b. It comes to be pressed against the upper surface of the boss portion 9.
