DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
0, FIG. 11), the adjustment range of the tilt angle of the mirror body 4 is set to such an extent that it can cover the range required when traveling on a road under normal conditions. In addition, the operation speed is kept at a speed that can be adjusted with precision as practically necessary. This is because it is rather difficult to adjust to a desired angle if tilting too fast. However, under special driving conditions such as when moving backward near the shoulder of a road or when performing a side-by-side driving operation, there is a case where it is desired to visually observe the vicinity of the rear wheels by the reflected image of the door mirror. In order to bring the reflected image near the rear wheels into the driver's field of view, it is necessary to tilt the door mirror downward by a certain angle as compared with the door mirror angle during normal driving. The above-mentioned constant angle varies depending on the type of the vehicle, and is 5 to 7 °, but it is a substantially constant angle for a certain type of vehicle. (See FIG. 12) When the own vehicle 21 is traveling on the road, it is normally sufficient to visually recognize the state of the following vehicle 22 as a reflected image, but when the overtaking vehicle 23 approaches, the angle θ As described above, it is desirable to be able to visually recognize a wider reflection field in the left and right than in the normal case. Further, as shown in FIG. 13, when entering an expressway, it is desirable to have a reflective view such that a following vehicle traveling on the main line can be visually recognized like an angle φ. In the conventional remote control type door mirror, it is not impossible to expand the working range of the drive unit to cover the mirror angle at which the rear wheels can be visually observed, but there are the following problems. (A) Expand the range of mirror tilt angle vertically and horizontally,
When the mirror tilting speed is not changed, the operation time is long and inconvenient. (B) If the tilting speed is increased in proportion to the expansion of the mirror tilting angle range, precision operation cannot be performed during remote control during normal traveling. (C) Further, in any of the above cases (a) and (b), when the vehicle is returned from the normal running state to the rear wheel confirmation posture or the side vehicle confirmation posture and then returned to the normal traveling state again, Since the adjustment before the confirmation posture or the side vehicle confirmation posture has been lost, it has to be readjusted.
It's inconvenient.

The present invention has been made in view of the above-mentioned circumstances, and it can be quickly and easily performed as necessary without affecting the operation accuracy of the original remote control, and the normal running state and the rear wheel checking state or the side. It is possible to perform a switching operation for accurately tilting by a predetermined angle between the two-wheel vehicle confirmation state, and the mirror angle adjustment state in the normal traveling state is stored, and the rear wheel or the side vehicle confirmation state is followed by the normal traveling state. and to provide an electric remote control mirror may Rukoto allowed restored correctly when operating so as to restore to the state.

In the drive unit housing 1 ', a forward / backward moving rod 5a for left / right driving of the mirror and a forward / backward moving rod 5b for vertical driving of the same are provided, and the reduction gear groups 11a, 11b are respectively moved by motors 10a, 10b for changing the angle. Driven through. Advancing / retreating rod 5a for tilting the mirror in the left-right direction, and angle changing operation motor 10
The speed reduction gear group 11a includes an instantaneous actuation mechanism K for checking a side vehicle, which will be described later with reference to FIG. Further, the vertical drive mechanism (comprising the forward / backward movement rod 5b, the motor 10b, the reduction gear group 11b, etc.) is provided with a mirror tilting mechanism J for confirming the rear wheels, which will be described below with reference to FIG. FIG. 2 is a schematic diagram of the vicinity of the tilting mechanism J for confirming the rear wheels, which is drawn for convenience of explanation of the configuration and operation. In particular, it is not a view cut along one plane, but a view cut along a curved surface so that related members can be conveniently represented. The upper part of FIG. 2 corresponds approximately to the upper part of the apparatus, but since the cutting by the bending surface is developed in the upper and lower parts of the drawing, the upper and lower member arrangement relations in the drawing are not necessarily the actual ones of this embodiment. For reference of the reading, FIG. 14 is a reference diagram in which the detailed reference numerals of the mirror driving section of FIG. 2 are omitted and hatching is shown. Reference numeral 1'denotes a drive unit housing which supports a mirror body 3 via a ball joint 2 so as to be tiltable. Reference numeral 4 denotes a mirror body, which is fixed to the mirror body 3. The ball joint 2 is constructed by fitting a spherical seat 1a provided on the drive unit housing 1'and a spherical portion 3a provided on the mirror body 3 into each other.

[0008] 5b is a reciprocating rod of tubular, is the male screw 5b ₁ is formed on its outer circumference, square hole 5b ₂ is formed on its inner surface. Reference numeral 12 denotes a nut member that is screwed into the advancing / retreating rod 5b and screw-feeds the rod. The nut member 12 has a female screw 12a that is screwed into the male screw 5b ₁ and has a leaf spring-shaped outer periphery. A flexible male screw piece 12b is continuously provided integrally. Reference numeral 13 is a transmission member for rotationally driving the advancing / retreating rod 5b, and a drive angle shaft 13a is arranged at the center thereof. The drive angular shaft 13a is slidably fitted in the square hole 5b ₂ of the advancing / retreating rod 5b. The drive angular shaft 13a is engaged with the base gear 13b. Reference numeral 13c is a tooth of the base gear 13b. Reference numeral 13d is a friction transmission portion between the drive angular shaft and the base gear. This base gear 13b
Is momentarily operated by an instantaneous operation motor 10c via an intermediate gear 14, a worm receiving gear 15, and a worm original gear 16 meshing with its teeth 13c, and when a torque of a predetermined torque or more is applied, the motor 10c slips and slips. It has become. When the present invention is implemented, the mechanism that slides with a predetermined torque as described above can be provided at an arbitrary position in the transmission system of the drive angular shaft 13a. For example, friction transmission bush 1
The frictional transmission portion 13d may be omitted by providing No. 4 and sliding at this position with a predetermined torque. However, it is convenient to provide it in the vicinity of the final stage of the reduction gear train as in the present embodiment because torque management is easier. In FIG. 2, when the angle changing operation motor 10b is rotated normally or reversely with the instantaneous operation motor 10c stopped, the drive cylinder 17 is normally or reversely rotated through the reduction gear group 11b. The drive cylinder 1
7, the male screw 12b of the nut member 12 is screwed into the female screw 17a of the nut member 7, and the nut member 12 is locked against rotation with respect to the drive unit housing 1'by guide means (not shown), You are guided in the direction.

Therefore, the nut member 12 is screw-fed in the left-right direction in the drawing by the rotation of the drive cylinder 17. Advancement rod 5
b is moved together with the nut member 12 because the male screw 5b _{1 on} the outer peripheral surface is screwed into the nut member 12 and the rotation is suppressed by the drive angle shaft 13a, and the mirror body body 5b is moved through the ball 5b _3. Tilt 3 up and down. Further, when the motor 10b is stopped and the motor 10c is rotated, the transmission member 13
Is rotated, the drive angular shaft 13a rotates the advancing / retreating rod 5b, and feeds the screw to the left and right in the drawing. When the advancing / retreating rod is screw-fed in the extending direction (leftward in the drawing), the mirror body 3 tilts downward (counterclockwise in the drawing). As shown in FIG. 2, stoppers 5b ₅ and 5b ₆ are provided at both ends of the male screw 5b ₁ of the advancing / retreating rod 5b, and the screw feeding stroke of the nut member 12 with respect to the female screw 12a is limited to the dimension s. There is. The advance / retreat rod 5b and the stopper 5b
₅ , 5b ₆ and the exploded perspective view of the nut member 12 are shown in FIG.
Shown in With a flange-shaped stopper flange 5b ₅ is integrally connected to the ball 5b ₃ side of the reciprocating rod 5b, ring groove 5b ₇ is formed at the end on the opposite side. A stopper retaining ring (so-called snap ring) 5b ₆ is fitted into the ring groove 5b ₇ . As described above, the motor 1
0b and the motor 10c tilt the mirror body 3 independently of each other, and when the tilt of the mirror body 3 reaches the stroke end and the stopper of the advancing / retreating rod operates, the engagement portion 13d is disengaged. Gear 13b
Spins. In this example, the rotation speed of the motor 10c is about 1.56 times that of the motor 10b. Further, the reduction gear group 11b has a gear ratio of about 2.2 times that of the transmission gears. As a result, the tilting of the mirror body 3 by the motor 10b is 3.3 seconds / 10 degrees, the tilting of the mirror body 3 by the motor 10c is 0.5 seconds / 10 degrees, and the tilting of the mirror body 3 by the motor 10c. Is done very quickly. Next, the operation of the electric remote control mirror of this embodiment constructed as described above will be described.
FIG. 5A illustrates a normal running state of the remote control mirror of the embodiment shown in FIG. The motor 10b for angle changing operation is operated according to the sitting height of the driver and other conditions to arbitrarily adjust the dimension L shown in the figure to adjust the bearing angle of the mirror body 4 as desired.

In the normal running state of FIG. 5 (A), FIG.
The operation switch mechanism described later will be operated to rotate the motor 10b for changing the angle and to rotate the drive cylinder 17 via the reduction gear group 11b. When the drive cylinder 17 is rotated, the female screw of the drive cylinder 17 and the male screw of the nut member 12 are rotated. Since and are screwed together, the nut member 12 is screw-fed in the left-right direction in the drawing. Figure 5
When the nut member 12 is screw-fed to the left in (A), the dimension L shown in the drawing increases, and the nut member 12 moves forward and backward 5b.
The screw rod 5b is extended leftward while being screwed, and the mirror body 3 is rotated clockwise, as shown in FIG. 5B. FIG. 5B shows a state in which the stroke is moved to the full stroke so as to facilitate the reading, but in actual use, it is sufficient to adjust the tilt of a minute angle. Similarly,
When the angle changing operation motor 10b is rotated in the opposite direction to that in the case of the above (B), the dimension L is reduced, and the advancing / retreating rod 5b contracts to the right in the figure to rotate the mirror body 3 counterclockwise. When moved, it becomes as shown in FIG. The normal running state in (Fig. 5 (A)) from actuating the motor 10c for instantaneous operation to the right in FIG forward and backward lever 5b, stopper 5b ₅ is as when the screw feeding in shrinkage direction 2 Acts, and resistance is applied to the transmission member. Therefore, frictional transmission between the drive angular shaft 13a and the base gear 13b slips, the driven side (mirror base 3 and the like) stops, and the drive side (motor 10c and the like) runs idle. In this way, an excessive torque is released, so that an unreasonable force is not applied to the transmission member, especially the screw feed mechanism.
This prevents the screw member from biting. This Figure 6
In this state, the dimension L shown in the figure has not changed from that shown in FIG. In this way, the mirror body 4 tilts downward and the rear wheel confirmation state is obtained. When the motor 10c is actuated again to reverse the base gear 13b and the drive angular shaft 13a, the advancing / retreating rod 5b contracts to the right in the figure, and the mirror body 3 is tilted upward with the dimension L unchanged. The restoration to the state of FIG. When the advancing / retreating rod 5b is fully contracted with respect to the nut member 12, the engagement between the base gear 13b and the drive angular shaft 13a is disengaged and the restoration is completed, and the normal traveling state (FIG. 5 (A)) is obtained. In this way, the motor 10c is remotely controlled without changing the dimension L (the value that determines the bearing angle of the mirror body 3 in the normal traveling state) adjusted according to the conditions of the individual drivers, and the normal traveling state is controlled. It is possible to switch between the rear wheel confirmation state and the rear wheel confirmation state, and moreover, it is possible to accurately restore the mirror bearing angle in the normal traveling state before the rear wheel confirmation state (dimension L is unchanged), and The switching operation of the motor 10
Since the adjustment is carried out by means of c, it is carried out independently of the mirror support angle adjustment by the motor 10b, and rapidly at an angular velocity about 6 times that of the mirror support angle adjustment by the motor 10b.
The stopper action for restricting the tilting stroke of the mirror body 3 has stoppers 5b ₅ and 5 provided on the advancing / retreating rod 5b.
The b _6, since is performed by limiting the feed screw stroke size, the mirror tilt angle to the rear wheels confirmation state is controlled exactly a predetermined angle from the normal running state. Further, as shown in the sectional view of FIG. 2, the screw feed mechanism when driven by the motor 10b and the screw feed mechanism when driven by the motor 10c have a triple tubular telescopic structure (drive). Since it has a triple structure of the cylinder 17, the nut member 12, and the advancing / retreating rod 5b), it can be constructed in a small size.

FIG. 4 shows an embodiment different from that shown in FIG. Reciprocating rod 5b of this example 'is provided with a stopper flange 5b ₉ at the opposite end of the sphere 5b _3, fitting the stopper retaining ring 5b ₆ to near the base of the sphere 5b ₃ is provided a ring groove 5b ₈ structure Is. The embodiment shown in FIG. 3 and the embodiment shown in FIG. 4 have the same basic configuration in that they are provided at both ends of the male screw 5b ₁ and provided with stopper means for limiting the screw feed stroke. When implementing the present invention, whether to apply the embodiment of FIG. 3 or the embodiment of FIG. 4 can be arbitrarily selected with reference to the following matters. The stopper flange is superior to the stopper retaining ring 5b _{6 in} positioning accuracy when stopping the screw feeding of the male screw 5b ₁ with respect to the female screw 12a of the nut member 12. On the other hand, the accuracy of the tilt angle of the mirror is generally desired to be higher when the vehicle is restored to the normal traveling state than when it is in the rear wheel confirmation state. Therefore, when the advancing / retreating rod expands to the rear wheel confirmation state and the advancing / retreating rod contracts to restore the normal traveling state as a result of the disposition of the related components, the embodiment of FIG. 3 is preferable. In the opposite case (decompress and restore)
It is desirable to apply the embodiment of FIG.

2 is a sectional view including the forward / backward moving rod 5b for vertically tilting the mirror and the tilting mechanism J for confirming the rear wheels shown in FIG. FIG. 3 is a cross-sectional view including a forward / backward moving rod 5a for tilting and a tilting mechanism K for checking a side vehicle, and a vertical direction in the drawing corresponds to a left-right direction with respect to a vehicle body. Since FIG. 6 is a sectional view of the same embodiment as FIG. 2, the members designated by the same reference numerals as those in FIG. 2 are the same constituent members as in FIG. The tilting mechanism for checking the side vehicle shown in FIG. 6 has a configuration similar to that of the tilting mechanism for checking the rear wheels shown in FIG. That is, 10d instantly expands the left and right tilting range of the mirror for checking the side vehicle,
It is an instantaneous operation motor for restoring, and rotates the transmission member 23 via the worm original gear 26 and the worm receiving gear 25. When the transmission member 23 rotates, its driving angular axis 2
3a is wound is reciprocating rod 5a so fitted into the square hole 5a _2, because the male thread 5a ₁ is screwed into the nut member 22 and the forward-reverse in the lateral direction of the drawing, FIG mirror body 3 In, tilts clockwise and counterclockwise (left and right with respect to the vehicle body (not shown)). The adjusting operation in the left-right direction (changing operation) in the normal traveling state is performed by the changing operation motor 10a.
Thus, the drive cylinder 27 is rotated via the reduction gear group 11a. When the drive cylinder 27 rotates, the female screw 27a and the male screw 22b of the nut member 22 are screwed together, so that the nut member 22 is screw-fed in the left-right direction in the drawing, and the advancing / retreating rod 5a is moved together with this. The mirror body 3 is tilted by being screwed in the left-right direction in the figure. As described above with reference to FIG. 2 and FIG. 6, during normal traveling, the mirror body 3 can be tilted up and down relatively slowly and precisely by the angle changing operation motor 10b to perform the vertical angle changing operation and the angle changing operation. By the operation motor 10b, the mirror body 3 can be tilted left and right relatively slowly and precisely to perform a left and right angle changing operation. Then, if necessary, the instantaneous operation motor 10c may be temporarily operated.
This allows the mirror body 3 to be rapidly tilted downward by a certain angle to bring it to the rear wheel confirmation state or to restore the normal running state, and when necessary, the mirror body 3 is moved to the left or right by a temporary operation motor 10d. The vehicle can be tilted by a certain angle to the side vehicle confirmation state or restored. FIG. 7 is a cross-sectional plan view when the motor 10d is operated to bring the vehicle into the side vehicle confirmation state. The four motors 10a, 10b, 10c and 10d are incorporated in one drive unit housing 1 ', and cooperate with each other to tilt one mirror body 3 vertically and horizontally freely.
When the electric remote control mirror is actually mounted on the vehicle, the drive unit housing 1'and the mirror body 3 having the above-described configurations are provided on the left side and the right side of the vehicle body, respectively.
To place. As described above, the electric remote control mirror of this embodiment has four drive housings 1'in one drive housing 1 '.
It houses one motor, and these four motors move one mirror body (with a mirror attached) up and down,
Since it can be operated to change the angle to the left and right and can be instantaneously operated and restored, this set of drive unit housings 1'can be used for the right side and the left side of the automobile body. More specifically, the mirror base and the mirror housing are separate members for the right side and the left side, which are symmetrical with each other (so-called left and right), but the remote controller drive section (drive section housing 1 ') installed in the mirror housing. And an assembly part including the storage member thereof can be used for both the left side and the right side of the vehicle body and have compatibility. In this way, if the assembly parts called sub-assemblies are compatible, the cost reduction effect can be obtained by the small-lot mass-production, and the supply parts management is also advantageous. FIG. 7 described above shows the case where the drive unit is used for the right side door mirror, and the stopper 5b ₅ is hit to check the right side vehicle. If you use the same drive section unit for the left door mirror a state to check the left side wheel when the stopper 5b ₆ hits.

FIG. 8 shows an operation system diagram of the four motors 10a to 10d housed in one drive unit housing to tilt one mirror body as described above. Reference numeral 10a is a motor for left / right angle changing operation, and 10b is a motor for vertical angle changing operation. These angle changing operation motors 10a, 1
The macro function of 0b is similar to the two motors 10 in the conventional example (FIG. 10). The angle changing operation motors 10a and 10b in the present embodiment are connected to a DC power source (battery) BT through a known remote control switch, and are wired so that they can be rotated forward and backward independently of each other. The up / down instantaneous operation motor 10c is connected to the DC power source BT via a double pole double throw type forward / reverse / stop changeover switch 32, and the left / right instantaneous operation motor 10d is a double pole double throw double forward / reverse / stop switch. It is connected to the DC power supply BT via the switch 33. As a result, the four operation motors 10a to 10d can be independently rotated, arbitrarily rotated in the forward direction, the reverse direction, and stopped. FIG. 9 shows an embodiment different from the above. Although not shown in the drawing, the two angle changing operation motors 10
As in the case of FIG. 8 described above, a and 10b are connected to a DC power source through a known remote control switch, and can be freely changed in normal traveling condition. The up / down instantaneous operation motor 10c is controlled by the reverse signal of the shift lever via the controller 34 to perform forward / reverse rotation / stop control. Specifically, the up / down instantaneous operation motor 10c is normally rotated by a reverse signal indicating that the transmission of the vehicle equipped with the electric remote control mirror of this embodiment is operated in the backward direction, so that the mirror body is in the rear wheel confirmation state. Tilt to. When the transmission is operated forward or neutral and the reverse signal disappears, the instantaneous operation motor 10c is reversely rotated to restore the normal traveling state. Further, when the vehicle equipped with the electric remote control mirror of this embodiment operates the turn signal lamp for turning or changing the course, the left / right instantaneous operation motor 10d is normally rotated by the turn lamp signal, and the vehicle equipped with the mirror body. Inclining in the steering direction of to bring the side vehicle into a confirmed state. Then, when the mounted vehicle returns to the straight traveling state and the turn lamp signal disappears, the left and right instantaneous operation motor 10d reverses to tilt the mirror body,
Restore the running condition. The instant operation in this embodiment (FIG. 9) is automatically performed in accordance with the forward, backward, or left or right steering of the vehicle, and the driver's intention does not affect the operation. However, the tilt angle due to the instantaneous operation of the mirror body is
Since it is regulated by the stroke size (for example, size s shown in FIG. 2) of the screw feed to the nut member of the advancing / retreating rod, instantaneous tilting of a predetermined angle can be performed without requiring direct operation of the driver. And accurately restores the original state (the mirror angle in the normal running state before the instantaneous operation).

[0014]

As described above, according to the configuration of the present invention, the normal running state and the rear wheel checking state or the rear wheel checking state can be quickly and easily performed as necessary without affecting the original remote control operation accuracy. Between the side vehicle confirmation state,
It is possible to accurately perform a fixed angle switching operation based on the adjustment state of the mirror angle in the normal running state. Moreover, the mirror angle adjustment state in the normal running state is stored, and the rear wheel confirmation state or the side vehicle confirmation is performed. restored accurately so when operating from a state to be restored to the normal running state
It exhibits an excellent practical effect that it is tighten Rukoto.
