[0003]

[Problems to be solved by the device]

 The adjustment range of the tilting angle of the mirror body 4 by the driving unit (FIGS. 10 and 11) is set to such an extent that it can cover the range required when traveling on a road under normal conditions. In addition, its operating speed is kept at a level that can be adjusted with the precision required for practical use. This is because it is rather difficult to adjust to the 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 desirable 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 compared to the angle of the door mirror during normal driving. The above-mentioned constant angle differs depending on the type of the automobile, and is 5 to 7 °, but it is almost constant for a certain type of automobile. (Refer to 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 It is desirable to be able to see a wider reflection field to the left and right than in the normal case. In addition, as shown in FIG. 13, when entering an expressway, it is desirable to have a reflective field of view such that a following vehicle traveling on the main line can be visually recognized at an angle φ. In the conventional remote control type door mirror, it is not impossible to expand the operation range of the drive unit to cover the mirror angle at which the rear wheels can be visually observed, but the following problems occur. (A) When the range of the mirror tilt angle is expanded vertically and horizontally and the mirror tilt speed is not changed, the operation time is long and inconvenient. (B) If the tilting speed is increased corresponding to the expansion of the tilting angle range of the mirror, the precision operation cannot be performed during remote control during normal traveling. (C) Further, in both cases (a) and (b), when the vehicle is returned from the normal running state to the rear wheel checking posture or the side vehicle checking posture and then returns to the normal running state, the previous (rear) It is inconvenient because the adjustment before the wheel confirmation posture or the side vehicle confirmation posture has been lost and it is necessary to readjust it.

The present invention has been made in view of the above-mentioned circumstances, and can quickly and easily perform the normal running state and the rear wheel check state or the side vehicle check state without affecting the original remote control operation accuracy. It is possible to perform a switching operation for accurately inclining by a predetermined angle between the two, and the mirror angle adjustment state in the normal running state is stored, and the rear wheel or side vehicle confirmation state is restored to the normal running state. It is an object of the present invention to provide an electric remote control mirror that can be accurately restored when operated like this.

[0005]

[Means for Solving the Problems]

 As a configuration for achieving the above object, the present invention supports a mirror body so as to be tiltable with respect to a housing of a mirror drive unit, and also has one end of two movable rods with a screw provided on the drive unit. Each of them is connected to the mirror body via a ball joint, and each of the threaded advancing / retreating rods is screw-fed by a bending operation motor via a screw member that is screwed into each of the screw advancing / retreating rods to move the mirror body up and down. ， In an electric remote control mirror that can be tilted to the left and right, two tubular advancing and retracting rods with male threads on the outer periphery and relative rotation with respect to the center holes of each of the tubular advancing and retracting rods are engaged. A drive shaft that is stopped and slidably fitted, and two nut members having female threads that are respectively engaged with the male threads of the advancing / retreating rod provided with the male thread, and the above-mentioned nut member. Two members that are provided on the outer peripheral side thereof and that function as male screws, a drive cylinder that has a female screw hole that engages with the above-mentioned member that functions as a male screw, and the above-mentioned drive cylinders that rotate forward and backward respectively. And a switch capable of operating the above two instantaneous operation motors independently of each other.

[0006]

[Action]

 According to the above configuration, when the drive cylinder is rotated and the male screw member provided on the outer periphery of the nut member is screw-fed, the nut member is screwed while maintaining a constant screwing relationship with the male screw of the advancing / retreating rod. It is sent, and the advancing and retracting rod is moved forward and backward. As a result, it functions as a normal remote control mirror. When the drive shaft is independently rotated regardless of the nut member, the advancing / retreating rod is rotated and screwed to the nut member. As a result, in addition to the function as a normal remote control mirror, the mirror can be temporarily tilted downward or sideways to the rear wheel or side vehicle confirmation state or to restore the normal running state. Be done. Moreover, this operation is performed independently of the above-mentioned nut member, and since the nut member is not rotated, it does not affect the mirror support angle in the normal traveling state and can be accurately restored. As a total effect of the above-mentioned operation, the electric remote control mirror of the present invention can quickly and easily check the normal running state and the rear wheels or side vehicles without affecting the original remote control operation accuracy. It is possible to accurately perform a predetermined angle switching operation between the state and the state, and remember the mirror angle adjustment state in the normal running state to restore from the rear wheel or side vehicle confirmation state to the normal running state. Can be restored accurately when operated like.

【Example】

 FIG. 1 shows a driving unit in an embodiment of the present invention and is a view corresponding to FIG. 10 in the conventional example. In the drive unit housing 1 ', there are provided an advancing / retreating rod 5a for left / right driving of the mirror and an advancing / retreating rod 5b for vertically driving the same. Driven via 11b. The advancing / retreating rod 5a for tilting the mirror in the left-right direction, the angle changing operation motor 10a, and the reduction gear group 11a are provided with an instantaneous actuation mechanism K for confirming a side vehicle, which will be described later with reference to FIG. Further, the mechanism for vertically driving (composed of a forward / backward rod 5b, a motor 10b, a 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 view of the vicinity of the tilting mechanism J for checking the rear wheels, which is drawn for convenience of explanation of the structure 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 curved 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, a reference diagram in which the detailed reference numerals of the mirror driving section of FIG. 2 are omitted and hatching is shown in FIG. 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.

Reference numeral 5b is a tubular rod that has a male and female screw 5b ₁ formed on its outer periphery and a square hole 5b ₂ formed on its inner surface. Reference numeral 12 denotes a nut member that is screwed into the advancing / retreating rod 5b and screw-feeds it, and has a female screw 12a that is screwed into the male screw 5b ₁ and has a leaf spring-like outer periphery. Flexible male screw pieces 12b are integrally provided in series. 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 angle shaft and the base gear. The base gear 13b is rotationally driven by an instantaneous operation motor 10c via an intermediate gear 14, a worm receiving gear 15, and a worm original gear 16 that mesh with the teeth 13c of the base gear 13b. 10c is designed to idle. 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, the friction transmission portion 13d may be omitted by providing the friction transmission bush 14 and sliding at this portion with a predetermined torque. However, as in this embodiment, it is convenient to provide it in the vicinity of the final stage of the reduction gear train 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. A male screw 12b of a nut member 12 is screwed into a female screw 17a of the drive cylinder 17, and the nut member 12 locks the rotation with respect to the drive unit housing 1'by a guide means (not shown). And is guided in the axial direction.

Therefore, the nut member 12 is screwed in the left-right direction in the drawing by the rotation of the drive cylinder 17. Reciprocating rod 5b, since the male screw 5b ₁ of the outer peripheral surface is suppressed rotated by screwed or One drive angle shaft 13a to the nut member 12 is moved together with the nut member 12, through the sphere 5b ₃ Tilt the mirror body 3 up and down. Further, when the motor 10b is stopped and the motor 10c is rotated, the transmission member 13 is rotated, and the drive angular shaft 13a rotates the advancing / retreating rod 5b to feed it to the left and right in the figure. When the advancing / retreating rod is screw-fed in the extending direction (left in the figure), the mirror body 3 tilts downward (counterclockwise in the figure). 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 feed stroke of the nut member 12 to the female screw 12a is limited to the dimension s. There is. FIG. 3 shows an exploded perspective view of the advancing / retreating rod 5b, the stoppers 5b ₅ and 5b ₆ , and the nut member 12. With a flange-like Sutoppafura Nji 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. In the ring groove 5b _7, the stopper retaining ring (so-called snap ring) 5b ₆ is fitted. As described above, both the motor 10b and the motor 10c tilt the mirror body 3 independently of each other, and when the tilting of the mirror body 3 reaches the stroke end and the stopper of the advancing and retracting rod is actuated, the engaging portion is engaged. 13d is disengaged and the base gear 13b runs idle. In this example, the rotation speed of the motor 10c is about 1.56 times that of the motor 10b. Further, the gear ratio of the transmission gears is about 2.2 times in the reduction gear group 11b. 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. The tilting is extremely quick. 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. According to the sitting height of the driver and other conditions, the motor 10b for angle changing operation is operated 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), the operation switch mechanism described later with reference to FIG. Then, since the female screw of the drive cylinder 17 and the male screw of the nut member 12 are screwed together, the nut member 12 is screw-fed in the left-right direction in the drawing. In FIG. 5 (A), when the nut member 12 is screw-fed to the left, the illustrated dimension L increases, and the nut member 12 is screwed into the advancing / retreating rod 5b and the advancing / retreating rod 5b is extended to the left to extend the mirror body. 3 is rotated in the clockwise direction, as shown in FIG. In Fig. 5 (B), the state is shown 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 angle at a minute angle. Similarly, when the angle changing operation motor 10b is rotated in the direction opposite to that in the case of the above (B) figure, the dimension L is reduced, and the advancing / retreating rod 5b contracts to the right side of the figure to move the mirror body 3 counterclockwise. It is rotated in the direction of rotation, as shown in Fig. 5 (C). When the motor 10c for instantaneous operation is operated from the normal running state (FIG. 5A) to screw the advancing / retreating rod 5b to the right in the drawing in the contracting direction, the stopper 5b becomes as shown in FIG. ₅ 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, excessive torque is released, so that no excessive force is applied to the transmission member, especially the screw feed mechanism. This prevents biting of the screw member. In the state shown in FIG. 6, the dimension L shown in the figure is the same as 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 operated 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. , Start to restore 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 is obtained (FIG. 5 (A)). In this way, the motor 10c can be remotely controlled without changing the dimension L (the value that determines the bearing angle of the mirror body 3 in the normal running state) adjusted according to the conditions of the individual drivers. 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 support angle to the normal traveling state before the rear wheel confirmation state (dimension L does not change), and Since the switching operation is performed by the motor 10c, it is rapidly performed independently of the mirror support angle adjustment by the motor 10b and at an angular velocity about 6 times as high as the mirror support angle adjustment by the motor 10b. The stopper action that limits the tilting stroke of the mirror body 3 is performed by limiting the screw feed stroke size by the stoppers 5b ₅ and 5b ₆ provided on the advancing / retreating rod 5b. The mirror tilt angle up to the state is accurately controlled to a constant angle. Further, as shown in the cross-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 FIG. 3 described above. 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 structure 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. In carrying out 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. Positioning accuracy when stopping the screw feed of the male screw 5b ₁ for female thread 12a of the nut member 12, towards the stopper flange is better than the stopper retaining ring 5b _6. 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 running state than when it is in the rear wheel confirmation state. Therefore, when the advancing / retreating rod is extended to the rear wheel confirmation state and the advancing / retreating rod is contracted to restore the normal traveling state as a result of the disposition of the related components, the embodiment of FIG. 3 is preferable. It In the opposite case (decompression and restoration), 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. 1, but FIG. FIG. 4 is a cross-sectional view including a forward / backward moving lever 5a for tilting and a tilting mechanism K for checking a side vehicle, in which the upper and lower directions in the figure correspond to the left-right direction with respect to the vehicle body. Since FIG. 6 is a cross-sectional view of the same embodiment as FIG. 2, the members designated by the same reference numerals 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 is an instantaneous operation motor for instantaneously enlarging and restoring the left and right tilting range of the mirror for checking the side vehicle, and the transmission member 23 via the worm original gear 26 and the worm receiving gear 25. Rotate. When the transmission member 23 is rotated, so that the driving angle shaft 23 a is fitted into the square hole 5a ₂ reciprocating rod 5a is wound, because the male thread 5a ₁ is screwed to the nut member 22 FIG. The vehicle moves forward and backward in the left and right directions and tilts the mirror body 3 in the clockwise and counterclockwise directions (left and right with respect to the vehicle body (not shown)) in the figure. In the left-right adjustment operation (changing angle operation) in the normal traveling state, the driving cylinder 27 is rotated by the changing angle operation motor 10a 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 figure, and together with this, the rod 5a is reciprocated. Is screw-fed in the left-right direction in the figure to tilt the mirror body 3. As described above with reference to FIGS. 2 and 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 mirror body 3 can be rapidly and temporarily tilted downward by a fixed angle by the instantaneous operation motor 10c so that the rear wheel confirmation state or the normal traveling state can be restored. Accordingly, the mirror body 3 can be temporarily tilted to the left or right by a certain angle by the instantaneous operation motor 10d so that the side vehicle can be confirmed 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 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 configurations are arranged on the left side and the right side of the vehicle body, respectively. As described above, the electric remote control mirror of this embodiment accommodates four motors in one drive unit housing 1 ', and one mirror body (the mirror is attached) by these four motors. Since it is possible to change the angle of up and down, left and right, and instantaneously operate and restore, this set of drive unit housings 1'can be used for both the right side and the left side of the vehicle body. More specifically, the mirror base and the mirror housing are separate members for the right side and the left side, which are symmetrical to each other (so-called left and right), but the remote controller drive unit (drive unit housing 1) installed in the mirror housing is different. ′ And its assembly member) can be used for both the left side and the right side of the vehicle body and are compatible. In this way, if the assembly parts called subassemblies are compatible, the cost reduction effect can be obtained by the small-lot, high-volume production, and the management of the spare parts is also advantageous. FIG. 7 shows the case where the drive unit is used for the right side door mirror, and the stopper 5b ₅ is in contact with the right side vehicle to check the side vehicle. If you use the same drive section unit for the left door mirror a state to check the left side lateral vehicle when the stopper 5b ₆ hits.

FIG. 8 shows an operation system diagram of the four motors 10a to 10d which are housed in one drive unit housing to tilt one mirror body as described above. Reference numeral 10a is a motor for laterally changing the angle, and 10b is a motor for vertically changing the angle. The macro functions of these angle changing operation motors 10a and 10b are similar to those of the two motors 10 in the conventional example (FIG. 10). The angle changing operation motors 10a and 10b in this 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 forward / reverse / stop changeover switch 32, and the left / right instantaneous operation motor 10d is a double-pole double-throw forward / reverse / stop. It is connected to the DC power source BT via the changeover switch 33. As a result, the four operation motors 10a to 10d can be arbitrarily rotated in the forward, reverse, and stopped directions independently of each other. FIG. 9 shows an embodiment different from the above. Although not shown, the two angle changing operation motors 10a and 10b are connected to a DC power source through a known remote control switch as in the case of FIG. Is becoming Then, 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. More specifically, a reverse signal indicating that the transmission of the vehicle equipped with the electric remote control mirror of this embodiment has been operated to move backward causes the vertical up / down instantaneous operation motor 10c to rotate in the forward direction, and the rear body of the mirror body is confirmed. Tilt to the state. When the transmission is operated forward or neutral and the reverse signal disappears, the momentary 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 turn lamp signal causes the left and right momentary operation motor 10d to rotate forward to mount the mirror body. Tilt in the steering direction of the car and set it to the side vehicle confirmation state. When the mounted vehicle returns to the straight running state and the turn lamp signal disappears, the left and right instantaneous operation motor 10d reverses to tilt the mirror body and restore the normal running state. 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 will does not affect his or her hand. However, since the tilt angle of the mirror body due to the instantaneous operation is regulated by the stroke size (for example, the size s shown in FIG. 2) of the screw feed with respect to the nut member of the advancing and retracting rod, it is possible to directly operate the driver. Instantaneous tilting of a predetermined angle is performed without need, and the original state (the mirror angle in the normal traveling state before the instantaneous operation) is accurately restored.

[Effect of the device]

 As described above, according to the configuration of the present invention, it is possible to quickly and easily perform the operation between the normal traveling state and the rear wheel confirmation state or the side vehicle confirmation state without affecting the original operation accuracy of the remote control. With this, it is possible to accurately perform a constant angle switching operation based on the adjustment state of the mirror angle in the normal running state, and the mirror angle adjustment state in the normal running state is stored, and the rear wheel confirmation state or side This has an excellent practical effect of being able to accurately restore when operating to restore the normal driving state from the direction confirmation state.
