[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for waterproofing a folding mechanism in a retractable door mirror in which a mirror body is displaceably disposed in a state of protruding from a door of a vehicle body and in a state of being prone. It has improved waterproofing ability against high-pressure car washing.

[0002]

2. Description of the Related Art FIG. 2 shows an example of the structure of a retractable door mirror. In this folding door mirror 10, a mirror base 12 is fixed to a door (not shown) of a vehicle body. A hollow shaft 14 is fixed upright on the mirror base 12 substantially vertically, and a frame 16 is arranged rotatably in the direction around its axis. A mirror body 18 is fixed to the frame 16. A tilting mechanism 24 including a motor 20 and a transmission mechanism 22 is disposed on the frame 16, and the driving force is applied to the shaft 14 to rotate the mirror body 18 around the shaft 14. Let it. The folding mechanism 24 is covered with a seal cap 26. A mirror holder 30 holding a mirror 34 is attached to the frame 16 via a mirror angle variable mechanism 28.

A harness sub-assembly (wiring) 40 for supplying power to the motor 20 of the tilting mechanism 24 and the motors 36 and 38 of the mirror angle varying mechanism 28 is guided from the vehicle body through the shaft 14 into the mirror body 18. Has been.

In the above arrangement, since the tilting mechanism 24 and the variable mirror angle mechanism 28 are electrical components, it is necessary to take waterproof measures against rain and car washing. Of these, the tilting mechanism 24
About, cover the seal cap 26 as described above,
Further, since water may enter from a fitting portion between the frame 16 and the seal cap 26, as shown in FIG. 3A, a sealing member 42 such as butyl tape or a seal sponge is attached to the fitting portion. Or as shown in (b),
Packing 4 between frame 16 and seal cap 26
4 is inserted and screwed.

[0005]

The waterproofing measures of the tilting mechanism shown in FIG. 3 are effective to some extent against rain and ordinary car washes, but are not effective against high-pressure car washes by a high-pressure car washer. It turned out to be enough. That is, as shown in FIG. 4, water can be prevented from entering the fitting portion between the frame 16 and the seal cap 26 by the seal member 42 and the like, but the harness sub-assembly 40 in the inner space of the shaft 14 can be prevented. It has been found that high-pressure car wash water is blown up from below through the gap 46 between the two and enters the collapsible mechanism arrangement space 48.

[0006] This invention is intended to solve the above-mentioned problems in the prior art and to provide a waterproof structure of a door mirror folding mechanism capable of exhibiting a sufficient waterproof ability even with high-pressure car wash water. It is.

[0007]

According to the present invention, there is provided a mirror base mounted on a door of a vehicle body, a hollow shaft erected on the mirror base, and rotatable around the axis with respect to the shaft. and a frame which is supported by, this
Attached to the frame of
A mirror body which is displaceably arranged in a state of face down in a state of protruding to the door Ri, mounted on said frame
Is a mirror arranged on the front opening of the mirror body, a wire guided into the mirror body through the vehicle in the mirror base and the shaft from the body,
Attached to said frame within said mirror body is driven by power supplied through the wiring,該Fu
Wherein the foldable mechanism for realizing the displacement movement of the achieved rotational operation the Mi <br/> Rabode with the the pivoting operation of frame, the
Within the mirror body, the shaft and the
And attached to the frame,
A seal cap for preventing water from entering the tilting mechanism.
In the door mirror provided, the shaft in the shaft
It is fitted in the gap between the wiring and closes the gap,
From the lower opening of the shaft to the inside of the seal cap
And a closing member that prevents water from entering the tiltable mechanism .

[0008]

According to the present invention, between the wiring in the shaft,
I put the closing member in the gap and closed the gap
With the lower opening of the shaft,
Water intrusion into the mechanism is prevented, and a sufficient waterproof effect can be exerted on high-pressure car wash water and the like.

[0009]

FIG. 1 shows an embodiment of the present invention. The retractable door mirror 1 in FIG. 1 is shown with a mirror base and a mirror body removed. Here, FIG.
The same reference numerals are used for the parts common to. A hollow shaft 14 is fixed upright on a mirror base (not shown) substantially vertically, and a frame 16 is arranged rotatably around its axis. A mirror body (not shown) is fixed to the frame 16. The frame 16 is provided with a tilting mechanism 24 composed of a motor and a transmission mechanism. The driving force is applied to the shaft 14 to rotate the frame 16 around the axis of the shaft 14.
The folding mechanism 24 is covered with a seal cap 26.

A harness sub-assembly (wiring) 40 for supplying power to the motor of the tilting mechanism 24 is guided from the vehicle body into the tilting mechanism arrangement space 48 through the inside of the shaft 14.

A seal member 42 such as butyl tape or seal sponge is attached to a fitting portion between the frame 16 and the seal cap 26, thereby preventing water from entering from the fitting portion. A ring-shaped seal sponge 50 is fitted into the harness sub-assembly 40 in the shaft 14 to close the gap 46 between the harness sub-assembly 40 in the shaft 14 and thereby the lower opening of the shaft 14. This gap 46 from 14a
Through the upper opening 14b and the retractable mechanism arrangement space 48 through the upper opening 14b to prevent high-pressure car wash water and the like from entering the retractable mechanism arrangement space 48 from the water inflow path 56. doing.

[0012]

Other Embodiments Various other embodiments of the present invention are shown in FIG.
(A) and (b) respectively show. (A) is a shaft 1
The grommet 52 is fitted in the lower opening 14a of the fourth and the harness sub-assembly 40 is passed through the grommet 52 in a relatively airtight manner, so that the water inflow path 56 in the shaft 14 is prevented. (B) shows a configuration in which a grommet 54 is fitted on the top of the shaft 14 and the harness sub-assembly 40 is passed through the grommet 54 in a relatively airtight manner to block the water inflow path 56.

[0013]

As described above, according to the present invention, the closing member is inserted into the gap between the shaft and the wiring.
And closed the gap, so the lower opening of the shaft
Prevents water from entering the folding mechanism inside the seal cap
As a result, a sufficient waterproof effect can be exerted on high-pressure car wash water and the like.
