Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rearview mirror device that is mounted on a vehicle and whose mirror angle is adjusted by remote control operation.

[Conventional technology]

A conventional remote control type rearview mirror device for a vehicle is disclosed in Japanese Patent Application Laid-Open No. 60-143, as illustrated in FIGS. 6 and 7.
The structure is usually as disclosed in Japanese Patent No. 155.

That is, in this rearview mirror device, a base member 3 is attached to a vehicle body or a door side surface l via a rubber sheet 2. The base member 3 pivotally supports the main body 5 of the rearview mirror device and also includes a rotation driving means therein.

This rearview mirror device main body 5 includes a mirror housing 6 formed in the shape of a modified bowl-shaped case that is approximately rectangular in front and has an opening in the front, and a mirror portion 8 disposed to close the opening of the housing 6. and a drive unit 7 provided inside the housing 6 for tilting the mirror part 8 up and down (vertical direction) and left and right (horizontal direction) to adjust the viewing angle.

[Problem that the invention seeks to solve]

In the conventional rearview mirror device as described above, the mirror part 8
The mirror part 8 must be tilted vertically and horizontally inside the housing 6 so that the mirror part 8 does not protrude from the opening of the housing 6.

For this reason, a gap must be provided between the periphery of the mirror part 8 and the housing 6 at a predetermined distance. Therefore, if the area of the mirror part 8 is made large to ensure a sufficient rear visibility range, the housing 6 will become even larger, which will increase the air resistance when the vehicle is running. There was a problem.

Furthermore, since the gap between the mirror part 8 and the housing 6 is large, rainwater, dust, etc. may enter through the gap and cause a failure of the mirror part drive unit 7 or rotational drive means inside the housing 6. There was a problem that it had an adverse effect such as causing rust.

Furthermore, as the housing 6 becomes larger, the rearview mirror device main body 5 also becomes larger and protrudes from the side of the vehicle body. It is easy to come into contact with the body, which is dangerous and a nuisance. In such cases, conventionally, the rearview mirror device main body 5 was rotated in the left-right direction (horizontal direction) using a remote control, and the mirror portion 8 was stored in a state parallel to the side surface of the vehicle body.

However, since this rotation operation to the retracted state utilizes the horizontal rotation drive means used to adjust the viewing angle of the mirror part 8, it is performed slowly and conveniently for fine adjustment of the mirror part 8. This will be done through movement. Therefore, there is a problem in that it takes a long time to rotate the rearview mirror device main body 5 through a large angle between the use position and the storage position, which is inconvenient and difficult to use.

For this reason, it is conceivable to separately install a mechanism for storing the hack mirror device main body 5 inside the vehicle body, but this is difficult to secure a storage space in the vehicle body, and the mechanism for storing it is complicated. There was a problem in that it was difficult to realize this because it had to be installed inside the narrow rearview mirror device main body.

In view of the above-mentioned points, the present invention has a structure in which the area of a portion of the rearview mirror is increased, the entire rearview mirror device is made compact, and the movement of the hack mirror device main body between the use position and the storage position can be quickly performed. The purpose of this invention is to provide a new simple remote control bank mirror device for vehicles.

[Failure to solve the problem]

The remote control type hack mirror device for a vehicle of the present invention has an integral structure in which a mirror plate is fitted over the entire opening of the mirror housing, and the mirror plate integrated with the housing is driven by vertical rotation drive means and horizontal rotation drive means. The device is adapted to be driven by means to adjust the viewing angle, and a part of the horizontal rotation drive means includes a storage rotation drive means for moving the hack mirror device main body between a use position and a storage position. It is characterized by being worn.

[For production]

By configuring as described above, even when the area of the end plate is increased to widen the rear visibility range, the end plate is integrally fixed to the opening of the housing without creating a gap around the end plate. Therefore, the outer shape of the housing itself can be reduced to make it compact and lightweight as a whole, and furthermore, the operation of moving the hack mirror device body between the use position and the storage position can be performed quickly. .

7 (not shown) to control the operation of the storage drive motor 70.

Note that, of course, various means other than those described above may be used as the device 75, such as one using a limit switch.

Further, a vertical rotation drive mechanism is provided in the vertical drive motor housing section 28 of the case 26, as shown in FIG.

This consists of a drive motor 41, a deceleration mechanism 42, and a telescopic rod mechanism 43. This drive motor 41 is connected to the mirror operation switch board 17 described above through a lead wire 18, and its drive is controlled.

A worm 45 is fitted to the drive shaft of the drive motor 41,
It is brought into mesh with the worm gear 46 of the reduction mechanism 42.

This reduction mechanism 42 has a cylinder part 47 erected in the center of a worm gear 46, and the cylinder part 47 is rotatably supported by a bearing on the case 26.

Further, the telescopic rod mechanism 43 has a female threaded groove formed in the cylinder portion 470, and a cylindrical opening 7 corresponding to the female threaded groove.
A male thread groove is formed on the outer periphery of the door 48, and a screw is inserted thereinto. These constitute a vertical rotation drive means.

This rod 48 is for tilting the mirror housing 6, and the housing 6 is supported by the tip of this rod 48 and a hinge 50 provided on the case 26 shown in FIG.

As shown in FIGS. 1 to 3, the housing 6 is formed into a modified bowl shape that is substantially rectangular in front and has an opening in the front. Then, the mirror plate 60 is fitted into the opening on the entire surface to form an integral structure.

With this configuration, compared to a conventional mirror in which the mirror is partially tilted inside the housing 6, the height of the mirror is approximately the same when the size of the mirror is the same. The size of this example can be reduced to about 10 cranes or about 10 to 20 fins in width.

A bracket 51 having the shape shown in the figure is also provided inside the housing 6 and fixed with screws 52 and 53. Then, this bracket 51 is placed over the case 26 of the mirror vertical direction rotation driving means, and the lower part of the bracket 51 is attached to the hinge 5.
Rotatably attached to 0. Further, the central protrusion of the bracket 51 is pivotally attached to and supported by the tip of the rod 48.

In addition, an opening 6 through which the case 26 is passed under the bracket 51.
A rubber bellows 62 is provided between the first part and the rearview mirror main body support part 10 to seal it.

Next, the operation of this example device configured as described above will be explained.

First, in order to tilt the angle of the mirror plate 60 in the horizontal direction, the drive motor 14 is operated by operating a switch on the mirror operation switch panel 17.
Rotate forward or reverse. Then, the rotation shaft 23 is rotated via the deceleration mechanism 15, and the housing 6, which is integrated with the case 26 and end plate 60, is moved from the position indicated by the solid line in FIG. It is tilted in the direction of arrow A or arrow B as shown, and the required viewing direction angle is 4.1? It is something that can be adjusted.

Next, in order to adjust the tilting of the mirror plate 60 in the vertical direction, the drive motor 41 is operated by operating a switch on the mirror operation switch panel 17.
Rotate forward or reverse. Then, the cylinder portion 47 of the deceleration mechanism 42 connected thereto rotates in the forward or reverse direction, and the rod 48 pivotally attached to the bracket 1-51 is telescopically fed by the screw mechanism. As shown in FIG.
0 can be tilted in the direction of arrow C or arrow C from the position shown by the solid line around the hinge 50 to the positions shown by the dashed-dotted lines, respectively, so that the angle can be adjusted in the desired viewing direction.

Next, a case will be described in which the main body 5 of the mirror imitation device 5 in use is moved to the storage position. Drive rotation. Then, the worm 72 rotates via the deceleration mechanism 71.

At this time, the clutch mechanism 2 that engages with this worm 72
The worm wheel 35 of No. 4 is in a stopped state where it is locked so as not to rotate by the worm 21 in the mirror horizontal rotation drive means 12 which meshes with the worm gear 22 of the rotation shaft together with the rotation shaft 23 .

Therefore, as the worm 72 rotates, the mirror vertical rotation driving means 25 and its case 26, as well as the housing 6 and the mirror +ff160 integrated therewith, revolve around the rotation shaft 23, and The storage position shown by the two-dot chain line in FIG.

Also, when returning the rearview mirror device main body 5 in the retracted state to the use position, the retracting drive motor 70 is reversely rotated by operating the mirror operation switch panel 17 to rotate around the rotation shaft 23. It revolves in the opposite direction to that described above, reaches the use position, and is stopped by the action of the angle control contact device 75.

Note that this movement between the use position and the storage position can be performed quickly by reducing the reduction ratio of the reduction mechanism 71.

Next, we will explain the case where an abnormal force is applied to the housing 6 of this rearview mirror, such as when something hits it. In such a case, the clutch mechanism 24 portion of the rotation shaft 23 rotates in the horizontal direction, and When the bearing cylinder part 31 inserted into the rotating shaft column 23 slides upward against the spring force of the compression coil spring 36, impact force and excessive force are applied to the drive mechanism and the door side part 1. Participation can be avoided.

If the direction of the housing 6 changes due to an impact force, it can be returned to its original position by turning the housing 6 by hand and sliding it on the clutch mechanism 24 portion.

In addition, in this example device, the end plate 60 is fixed to the housing 6 in close contact with the housing 6 and the rearview mirror body support part 10.
Since the bellows 62 is provided between the drive mechanism and the drive mechanism to seal the drive mechanism, rainwater, dust, etc. can be prevented from entering the drive mechanism, and the drive mechanism inside can be protected. Further, it is possible to eliminate the wind noise generated in the gap etc. that conventionally existed between the housing 6 and a part of the mirror.

Furthermore, since the drive motor 14, deceleration mechanism 15, etc. for horizontally tilting the mirror plate 60 are installed in the rearview mirror body support part 10 of the base member 3, the weight applied to the horizontal rotating shaft part 16 is reduced. can.

Therefore, the load applied to the horizontal rotating shaft portion 16 due to vibrations and the like when the vehicle is running can be reduced.
This makes it possible to further reduce the deviation in the position of the mirror plate 60 in the visual direction.

〔Effect of the invention〕

As described in detail above, according to the remote control rearview mirror device for a vehicle of the present invention, the mirror plate is fitted into the opening of the mirror housing to form an integral body, and these parts can be tilted as a unit in the horizontal and vertical directions. Since the viewing angle is adjusted, there is no gap between the periphery of the end plate and the housing, which has the effect of making it possible to downsize the housing.

Further, by reducing the size of the housing in this way, air resistance when the vehicle is running can be reduced.

In addition, a storage rotation drive means for moving the rearview mirror device body between the use position and the storage position is attached to a part of the horizontal rotation drive means, so that the storage and return operations of the rearview mirror device body can be quickly performed. It has the advantage of being convenient and easy to execute. Furthermore, since the storage rotary drive means is configured to share a part of the structure of the horizontal rotation drive means, the number of members can be reduced and the weight can be reduced compared to when these means are provided completely separately. This has the effect of being able to provide low-cost products.
