Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a resin insert for an automobile mirror bracket. The invention is particularly suitable for mounting a large door mirror.

[0002]

2. Description of the Related Art Conventionally, an insert for an automobile mirror bracket is usually a sheet metal insert manufactured as follows.

A relatively thick steel plate (usually 1.2 to 1.6)
mmt), the main body portion / mounting leg portion and the glass run portion are separately formed by press working, both are welded, and further, a nut or the like is welded if necessary.

However, the sheet metal insert is, as described above,
Since a steel plate with a high specific gravity (specific gravity of iron: about 8) is used, it is difficult to meet the recent demand for weight reduction of automobiles, and it is necessary to press work and weld it separately, which increases the manufacturing man-hours and shape. However, it has become difficult to deal with the curved side surface of the vehicle body these days.

For this reason, a resin insert which can easily be manufactured into a desired shape in a short time by injection molding, compression molding or the like by using a structural synthetic resin such as fiber reinforced plastic (FRP) which is easy to meet the demand for weight reduction of automobiles. Is proposed. (See JP-A-6-64445, etc.)

[0006]

However, the door mirror bracket manufactured by coating the resin insert with a polymer elastic material such as NBR or NBR / PVC was found to be mounted on an actual vehicle as a result of the study by the present inventors. If a large and heavy door mirror (such as a motor built-in type) is supposed to be attached, it is difficult to satisfy the standard strength (design strength obtained by multiplying the allowable stress by the safety factor). From this, it was found that there may be a problem with durability.

In view of the above, the present invention provides a resin insert for an automobile mirror bracket, which can be mounted on an actual vehicle to accommodate a large and heavy door mirror, and can be expected to have improved durability. To aim.

[0008]

The resin insert for an automobile mirror bracket of the present invention solves the above problems by the following constitution.

The bracket body and the mounting leg are integrally formed of structural synthetic resin, and the bracket body and the mounting leg are provided with a channel portion along the rear side thereof, and the channel portion is made of a polymer elastic material. In a resin insert for an automobile mirror bracket, in which a body is covered with a glass run portion or a separate glass run is assembled,
The reinforcing sheet metal insert is embedded in the groove bottom portion of the channel portion so as to extend over at least the mirror bracket body portion and the mounting leg portion.

[0010]

EXAMPLES The present invention will now be described in detail based on examples.

(1) In a resin insert (hereinafter simply referred to as "resin insert") 11 for an automobile mirror bracket of this embodiment, a bracket main body 13 and a mounting leg 15 are integrally molded with a structural synthetic resin. The bracket body 13 and the mounting leg 15 are provided with a channel portion 17 along the rear side thereof, and the channel portion 17 has an upper portion (bracket body portion side) 17a covered with a polymer elastic body.
The channel portion 17 has a structure in which a polymer elastic body is coated to form a glass run portion 19 or a separate glass run 20 is assembled.

Specifically, the bracket body 13 has a substantially right-angled triangle shape, and the hypotenuse side is a front pillar seal portion forming portion 16 having a curved cross section, and the perpendicular line side is the channel portion 17. The front pillar seal portion forming portion 16 and the upper channel portion 17a are respectively covered with a polymer elastic material, and are in contact with the front pillar. The front pillar seal portion 18 and the door belt line L
The upper glass run portion 19 located on the upper side of is formed.

A substantially right triangular mirror mounting portion 23 having a plurality of (three in the drawing) mirror mounting holes 21 is provided at a substantially central portion of the bracket body 13 having a triangular shape.

The mounting leg portion 15 is an inverted triangular connecting portion 2 formed on the lower side of the bracket body portion 13.
5 and the upper channel portion 1 of the bracket body portion 13
The lower channel portion 17b is continuous with the lower side of 7a. A separate glass run (channel type) 20 is assembled to the lower channel portion 17b to form a glass run portion located below the door belt line L. Assembling the glass run 20 to the lower channel portion 17b, as shown in the figure, the lower channel portion 17b in which the locking long holes 27 are formed at predetermined intervals is formed on both sides of the channel of the glass run 20. The locking lip portion 20a is locked.

Here, the lower channel portion 17b may also be covered with a polymeric elastic material to form a glass run portion, like the upper channel portion 17a of the bracket body 13.

At this time, that is, the connecting portion 25 having an inverted triangular shape
On both sides of the upper end of the vehicle, that is, at a position directly below the door belt line L, the vehicle exterior mounting seats 31, 31 for mounting the door panel.
However, at the lower end of the lower channel portion 17b, vehicle interior mounting seat portions 33 for mounting door panels are formed. Each of the mounting seats 31 and 33 has a mounting bolt hole 3
1a and 33a are formed.

(2) In the above structure, in this embodiment, the reinforcing sheet metal insert 29 is provided at the groove bottom of the channel portion 17,
At least the bracket body portion 13 and the mounting leg portion 15
Is buried over the door belt line L position. The thickness of this sheet metal insert 29 is
Usually 1.0 to 1.6 mmt, and the length is usually 80
~ 150mm At this time, the cross-sectional shape of the sheet metal insert 29 is not limited to the strip plate shape, as shown by the chain double-dashed line in the illustrated example. That is, it is extended to the outside of the vehicle, which is the glass suction direction side when the vehicle is running, and / or it is extended to the mirror mounting portion, to form an L-shaped or crank-shaped cross section.
You may reinforce each part.

The resin insert 11 is molded by setting the above-mentioned sheet metal insert 29 in a mold and using ABS resin,
Fiber reinforced polypropylene (PP) / polyamide (P
It is performed by injection molding or the like using a structural rigid resin material such as A).

(3) As described above, the resin insert 11 having the above-mentioned structure is formed by injection molding a polymer elastic body, and further, the glass run 20 is attached to the channel portion 17 to form the mirror bracket 35. Then, the mirror bracket is attached to the vehicle body (door panel) D, and the door mirror DM is attached to the mirror attachment portion. (See Figure 4) In this case,
Even if the door mirror M is large, the door belt line L portion, which is the rotation fulcrum portion of the rotation vector generated by the load of the door mirror M, is reinforced by the reinforcing sheet metal insert 29 having a flat surface in the same direction as the rotation vector. Therefore, it is possible to deal with strength and durability sufficiently.

The resin insert for an automobile mirror bracket of the present invention can be mounted on an actual vehicle and can be used for mounting a large and heavy door mirror, and can be expected to have improved durability.

[0021]

As described above, in the resin insert for an automobile mirror bracket of the present invention according to the present invention, the reinforcing sheet metal insert is hung over at least the mirror bracket main body portion and the mounting leg portion at the groove bottom portion of the channel portion as described above. Since it is buried, it has the following functions and effects.

When a door mirror bracket having a glass run portion made of a polymer elastic material or the like in the channel of the insert is attached to the door panel and the door mirror is mounted, the door belt line becomes a rotation fulcrum portion of a rotation vector generated by the load of the door mirror. The part is reinforced with a reinforcing sheet metal insert having a flat surface in the same direction as the rotation vector.

Therefore, the resin insert for a mirror bracket of the present invention can be mounted on an actual vehicle and can be used for mounting a large and heavy door mirror, and it is expected that the durability will be improved.
