Abstract

PURPOSE:To get a mirror device out of the way in the cases of a driving on a narrow place or an operation to go into a garage by making it possible to house a mirror device into a bonnet. CONSTITUTION:A mirror visor 1 is turnably attached to the side edge of a bonnet 3 by a rotational hinge 5 and can be housed into a hollow 6 by a reversal in a 180 deg. arc from its working position. A cover plate 7 is attached turnably to the opposite side place of the rotational hinge 5 by a hinge 8 and, when the mirror visor 1 is put in its working position, the plate is placed in one plane with the bonnet upper plate 3 and covers the opening of the hollow 6. The cover plate 7 is pushed into the hollow 6 by the mirror visor 1 when the mirror visor 1 is reversed to its housed position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a retractable motor vehicle mirror device.

Recently, door mirrors have become popular as rear-view mirrors for automobiles, but while these door mirrors have the advantage that the image is much easier to see than the conventional 7-angle mirrors, they do not protrude outward from the car body. They are large, and when driving in narrow spaces or parking in a garage, there is a high possibility of contact with other objects, which is rather inconvenient. As a countermeasure to this, folding door mirrors have been proposed that can be folded down along the vehicle body, but even with this, some degree of protrusion cannot be avoided.
The possibility of contact with other objects could not be eliminated.

The present invention has focused on this point and has been made for the purpose of providing a fully retractable mirror device, in which the mirror visor containing the mirror is placed at a use position protruding outside the vehicle body and facing toward the inside of the vehicle body. The mirror visor is attached to the side edge of the top surface of the bonnet via a rotating hinge so that it can rotate between the retracted positions when the mirror visor is in the retracted position. , is characterized by a drive power unit installed inside the hood that rotates the mirror visor.

Next, the present invention will be specifically explained with reference to illustrated embodiments.

In Figure 1, 1 is a mirror visor, 2 is a mirror, 3
4 is a bonnet top plate; 4 is a fender; 15 is a rotating hinge; the mirror 2 is supported by the mirror visor 1 via a well-known pivot bearing (not shown);
When in use, the fender 4 has a horizontally elongated shape with a portion thereof protruding further outward than the outermost part of the fender 4. The rotating hinge portion 5 is formed by providing a support shaft 5a at the corner that is on the f side and inside the vehicle body when the mirror visor 1 is in the use position, and the mirror visor 1 is rotated on the side edge of the bonnet top plate 3. It is rotatably attached via a hinge part 5. 6 is a four-part housing the mirror visor 1; 7 is a lid plate; the recess 6 is recessed in the bonnet plate 3 adjacent to the rotating hinge part 5; the mirror visor 1 is inverted 180 degrees from the use position; By doing so, it is stored in the recess 6 as shown by the chain line. Further, the cover plate 7 is rotatably attached to the upper edge of the four parts 6 at a position opposite to the rotating hinge part 5 by a hinge 8, and when the mirror visor 1 is in the use position, the hood plate 7 is flush with the plate plate 3. The mirror visor 1 is biased by a spring (not shown) so as to cover the opening of the fourth part 6, and is pushed into the fourth part 7 by the mirror visor 1 when the mirror visor 1 is reversed to the retracted position. ing.

11 is a visor gear attached to the support shaft 5a, 12 is a drive power section, and 13 is a visor gear attached to the output shaft 12a of the drive power section 12.
The visor gear 11 is connected to the drive gear 13 via an intermediate gear 14. The drive power section 12 is, for example, an electric device such as an electric motor, an electromagnetic slide/drive, or a power device that utilizes an engine's intake negative pressure or oil pressure from an oil pump. and rotate the storage position and open.

This mirror device has the above-mentioned configuration, and is shown in Figures 3 to 5.
The figure shows the state in which it is installed in a car.

In other words, the mirror visor'-1 is placed as close to the windshield 22 as possible on both side edges of the bonnet top plate 3 so that it is placed close to the driver in the same way as the door mirror. Protruding from the driver's standard eye point P, the appropriate rear viewing angle θ3. θ2. It is supported at an angle that provides θ3. Further, unlike a door mirror, the driver sees the mirror surface through the windshield 22, so the mirror visor 1 is provided at a position where it can be seen within the wiper sliding range W from the eye point (P).

FIG. 2 shows an example of wiring when an electric motor M is used as the drive power unit 12. Next, the configuration and operation will be explained with reference to FIG.

In the figure, 25 is a power supply battery, 26 is a use switch, 27 is a storage switch, and 28.29 is a self-holding contact 2.
8a, 29a and motor circuit opening/closing contacts 28b, 29b
30°31 is a diode, 3
2 is a position detection switch, 33 is an automatic/manual changeover switch, switches 26 and 27 are, for example, push-button type switches that do not have a self-holding sleep function, and position detection switch 32 is a movable contact 32a that rotates with the rotating hinge part 5 and a switch for use. Fixed contact 32b provided so as to be turned off in position and storage position
and are connected as shown.

Now, when the use switch 26 is pressed, the relay 28 is activated, the contacts 28a and 28b are turned on, and the motor M rotates in a direction to rotate the mirror visor 1 toward the use position. When the mirror visor 1 rotates a little, the movable contact 32a rotates counterclockwise in the figure and comes into contact with the fixed contact 321), the position detection switch 32 is turned on, and the relay 28 is self-held through the contact 28a, and is not used. Even if the push operation of the switch 26 is stopped, the motor M continues to rotate. When the mirror visor 1 rotates to the use position, the fixed contact 32a separates from the fixed contact 32b, the position detection switch 32 is turned off, the motor M stops, and the mirror visor 1 protrudes to the outside of the vehicle body in the same way as the door mirror. It will be in a used state. At this time, the cover plate 7 automatically covers the openings of the four parts 6.

Next, when the storage switch 27 is pressed while in the use position,
The motor M is reversely rotated by the reverse operation, the mirror visor 1 is rotated to the storage position, the motor M is stopped, and the mirror visor 1 is stored in the four parts 6.

In addition, the use switch 26 and the storage switch 27 are arranged around the driver's seat so that remote control can be performed from inside the vehicle, and if a mechanical type that uses hydraulic pressure or the like is used as the drive power section 12, Also, the switches that operate the switching valves and solenoid valves are placed around the driver's seat. The automatic/manual changeover switch 33 is for stopping the self-holding function by turning off, and each switch 26.2
When 7 is released, the motor M will stop at that position, which is used to change the field of view of the mirror.

In addition, although only one motor M is shown in FIG. 2, if the left and right mirror devices are provided with motors without interlocking them via an appropriate interlocking mechanism, two motors M are required as shown by the chain lines. Just connect the motors in parallel.

As is clear from the description of the embodiments above, according to the present invention, the mirror device can be stored inside the bonnet without protruding from the bonnet. Even if the mirror device is shaped like a mirror, it can be retracted as needed to eliminate the outward protrusion, and while its large size makes it easy to check the rear, it does not get in the way when driving in narrow spaces or parking in the garage. There is an advantage of being able to obtain a convenient mirror device that does not require much effort.
