Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a retractable outside mirror mounted on a front panel of a driver's seat of a cab-over type vehicle, and more particularly, to a mirror bracket front panel. It relates to improvement of the mounting structure.

[Conventional technology]

In general, a cab-over type vehicle has a mirror bracket mounted on a front panel of a driver's seat below a window opening formed in the front panel, and the mirror bracket has an outside mirror at an upper end. The lower shaft portion of the mirror mounting rod is mounted.

In FIG. 4 (perspective view) showing one example, reference numeral 1 denotes a front panel of a driver's seat of a cab-over type vehicle, and a mirror bracket 3 is provided below a window opening 2 formed in the front panel 1. Is installed.

Lower shaft portion 4a of mirror mounting rod 4 on mirror bracket 3
Is rotatably mounted, and an outside mirror 5 is mounted on the upper end of the mirror mounting rod 4.

The mirror mounting rod 4 has a long horizontal portion so that the outside mirror 5 protrudes outside the driver's seat.

On the other hand, a motor (storage motor) 6 as a drive source for displacing the outside mirror 5 to the storage position is provided inside the mirror bracket 3, and a gear provided on a drive shaft of the motor 6. Pinion 4b meshable with 6a
Is mounted on the lower shaft portion 4a of the mirror mounting rod 4.

When the car passes through a narrow place or parks in a narrow parking lot, the motor 6 rotates the mirror mounting rod 4 about the lower shaft portion 4a so that the horizontal portion is in front of the driver's seat. It is configured such that the outside mirror 5 can be displaced from a state in which the outside mirror 5 is located almost in the lateral direction to the outside of the driver's seat to a retracted state in which the outside mirror 5 is positioned within the vehicle width (a dotted line state in FIG. 4). ing.

When the motor 6 is driven in the opposite direction to the above case, it is needless to say that the outside mirror 5 can be returned from the storage position to the normal use position. It is also possible to change the position of the outside mirror by rotating the shaft portion 4a in the direction of arrow b.

[Problems to be solved by the invention]

By the way, in the conventional outside mirror mounting structure for a vehicle as described above, since the storing motor of the outside mirror is built in the mirror bracket, there is a problem that the mirror bracket is large and the appearance is poor. .

Also, when the outside mirror is retracted, it rotates around the lower shaft, which is mounted almost vertically, so that the outside mirror comes to the main part of the driver's field of view at the retracted position and hinders driving. In addition, there is a problem that the vehicle length for protruding forward becomes longer.

SUMMARY OF THE INVENTION The present invention is directed to solving the above-described problems in the conventional outside mirror mounting structure for a vehicle, and relates to an outside mirror in which a mirror bracket is disposed on a front panel of a driver seat of a cab-over type vehicle. The outside mirror storing motor is mounted inside the front panel so that the drive shaft is orthogonal to the front panel, and the mirror bracket is mounted on the drive shaft of the motor, and the mirror bracket is mounted along the front panel surface. The outside mirror for automobiles that can be rotated so that it can be stored in the driver's field of view without hindering driving when the outside mirror is stored and does not protrude forward, and the mirror bracket is downsized. It is an object to provide a mirror mounting structure.

[Means for solving the problem]

In order to achieve the above object, an outside mirror mounting structure for a vehicle according to the present invention is provided in a cab-over type vehicle on a front panel of a driver's seat of the vehicle below a window opening formed in the front panel. A mirror bracket, a mirror mounting rod having a lower shaft mounted on the mirror bracket, an outside mirror mounted on an upper end of the mirror mounting rod, and a motor for storing the outside mirror. The motor is mounted inside the front panel so that its drive shaft is orthogonal to the front panel, and the mirror bracket adjusts a gap between the mirror bracket and the front panel according to the rotation of the motor. When the mirror is used, it is attached to the front panel and the front panel. And a color bracket pressed, upon rotation of the bracket to the mirror storage location is characterized in that a gap is generated between the front panel and the mirror bracket.

[Action]

In the outside mirror mounting structure for an automobile of the present invention described above, when the outside mirror is stored, the mirror bracket rotates along the panel surface of the front panel to store the outside mirror out of the way of the driver. Act on.

Also, since the outside mirror storing motor is mounted inside the front panel, the size of the mirror bracket can be reduced.

Further, the mirror bracket is attached to the drive shaft of the motor via a mechanism for adjusting a gap between the mirror bracket and the front panel according to the rotation of the motor. When the mirror is used, the front panel and the mirror bracket are pressed against each other. When driving to the mirror storage position, a gap is generated between the front panel and the mirror bracket to reduce contact resistance.

〔Example〕

1 is a perspective view of the outside mirror mounting structure as one embodiment of the present invention, FIG. 2 is a sectional view taken along the line II-II of FIG. 1, and FIG. FIG. 3 is a sectional view taken along a cutting line different from the case of FIG.

In FIGS. 1 to 3, the same reference numerals as those in FIG. 4 denote substantially the same members.

The outside mirror mounting structure of this embodiment is also for mounting an outside mirror on the front panel of the driver's seat of a cab-over type vehicle, and the mirror is provided below the window opening 2 of the front panel 1 of the driver's seat. The bracket 10 is attached so that rotation along the panel surface of the front panel 1 can be performed.

That is, in FIG. 2 showing the detailed structure, a mounting plate 7 is mounted on the front panel 1 with bolts 8, and a female screw 7a is formed at the center of the mounting plate 7.

On the other hand, a male screw 10a that can be screwed with the female screw 7a is formed on the bottom surface 10b of the mirror bracket 10, and the distal end of the drive shaft 6b of the geared motor 6 for storing the outside mirror fixed to the front panel 1 has a male screw. It is engaged with the center of 10a by spline fitting.

The motor 6 is disposed inside the front panel 1 (on the side of the driver's seat), and the drive shaft 6b is orthogonal to the front panel 1 by tightening a nut 9 screwed into a male screw formed around the drive shaft 6b. Mounted on.

Therefore, the mirror bracket 10 merely holds the lower shaft portion 4a of the mounting rod 4 in a rotatable manner, and is smaller in size than the conventional case described above.

With the configuration described above, during normal operation of the vehicle, the horizontal portion of the mounting rod projects almost right beside the driver's seat, and the outside mirror protrudes from the driver's seat on the outer side diagonally forward of the driver (see FIG. 1). (The position shown by the solid line).

Then, the motor 6 is retracted to store the outside mirror 5.
Is driven, the mirror bracket 10 rotates in the direction of arrow a, that is, the direction in which the outside mirror 5 is tilted toward the center of the vehicle. This rotation is a rotation about the drive shaft 6b of the motor 6, and since the drive shaft 6b is mounted orthogonal to the front panel 1, the mirror bracket 10 rotates along the front panel 1. .

Since the male screw 10a of the mirror bracket 10 is screwed into the female screw 7a of the mounting plate 7, the mirror bracket 10
As the mirror bracket 10 rotates, the mirror bracket 10 rotates and gradually moves away from the mounting plate 7, and in the final stage, a gap is generated between the bottom surface 10b of the mirror bracket 10 and the front surface 7b of the mounting plate 7, and the contact resistance between the two. Is reduced. At this time,
The outside mirror 5 comes to a position shown by a dashed line in FIG. 1 via a position shown by a dotted line.

Then, in order to hold the mirror bracket 10 in this storage position, for example, a check ball as shown in FIG.
A clutch mechanism combining the coil spring 11 and the coil spring 12 is used.

It goes without saying that the return from the storage position to the overhang position is performed by rotating the motor 6 in the opposite direction to the above-described case.

At this time, that is, when the mirror is used, the bottom surface 10b of the mirror bracket 10 comes into pressure contact with the front surface 7b of the mounting plate 7, so that it is possible to suppress the occurrence of rattling during traveling of the vehicle.

In the above-described embodiment, the mirror bracket 10 is mounted on the front surface of the front panel 1. However, when the front panel has a 45.degree. The same effect can be obtained even if the horn is attached to this inclined portion of the front panel.

Also, an outside mirror is attached to the lower shaft portion 4a of the rod 4.
Can be stored in the same storage position as in the conventional case, and can be returned to the original position.

〔The invention's effect〕

As described in detail above, according to the outside mirror mounting structure for an automobile of the present invention, the following effects and advantages can be obtained.

(1) Since the rotating surface at the time of storing the outside mirror is substantially parallel to the panel surface of the front panel, there is no possibility that the outside mirror projects forward of the driver's seat during storage and does not obstruct the driver's view.

(2) Since the storage motor of the outside mirror can be mounted inside the front panel of the driver's seat, the size of the mirror bracket can be reduced.

(3) When the mirror bracket is damaged and replaced, the mirror bracket does not incorporate expensive components such as a motor, so that replacement can be performed easily at low cost.

(4) Since the mirror bracket is attached to the drive shaft of the motor via a mechanism for adjusting a gap between the mirror bracket and the front panel in accordance with the rotation of the motor, the front panel, the mirror bracket and the mirror bracket are used when the mirror is used. By pressing the mirror, rattling of the mirror can be suppressed when the vehicle is running. When the mirror is driven to the retracted position, a gap is generated between the front panel and the mirror bracket to reduce contact resistance between the two. be able to.
