  The vehicle mirror device according to claim 2 is the vehicle mirror device according to claim 1, wherein the moving mechanism includes a worm wheel connected to the additional body side, and the additional body communication side of the worm wheel. Is engaged with the opposite side and rotated to rotate the worm wheel, and the worm wheel is rotated to rotate the worm wheel.

  A vehicle mirror device according to a third aspect is the vehicle mirror device according to the second aspect, wherein the worm has a plurality of worms.

In the mirror device for a vehicle according to claim 1 is added adducts to mirror of the vehicle causes movement of the moving mechanism adduct from one deployed position and the retracted position at one side toward the other.

  Here, after the moving mechanism moves the additional body stopped by the stop mechanism to one of the deployed position and the storage position beyond the other of the deployed position and the stored position, the additional body moves to the other side (deployed position and By moving to the other side from the other storage position, the stop mechanism stops the additional body at the other of the deployed position and the storage position. Further, after the moving mechanism moves the additional body stopped by the stop mechanism to the other of the deployed position and the storage position to one side, the additional body is moved to the other side beyond the other of the deployed position and the stored position. Then, the stop mechanism stops the additional body at one of the deployed position and the retracted position.

Has been made possible.

  The worm 40 has a plurality of worms (for example, three worms). When the friction coefficient μ between the worm 40 and the helical gear 42 is 0.12 or more, the advance angle γ of the worm 40 is 7. More than (for example, 21 degrees). Thereby, not only the helical gear 42 is rotated by rotating the worm 40, but the worm 40 is rotatable by rotating the helical gear 42. Further, when the worm 40 is rotated by rotating the helical gear 42, the worm 40 applies a rotational resistance force to the helical gear 42.

An obstacle in the vicinity of the rear wheel (for example, in the vicinity of the rear wheel of the vehicle) (in particular, an occupant cannot be visually recognized by the mirror 18 and is lower than the lower end of the mirror 18 such as a pylon) can be detected.

  As shown in FIGS. 6 to 8, the bracket 20 and the moving body 22 are provided with a heart cam mechanism 54 as a stop mechanism at the center in the vehicle width direction and at the front side of the vehicle.

  The heart cam mechanism 54 is provided with a substantially rectangular plate-like locking plate 56 as a locking member, and the locking plate 56 is rotatably supported by the bracket 20 at the upper end portion. A wave washer (not shown) as a resistance means is sandwiched between the upper end portion of the locking plate 56 and the bracket 20, and the wave washer applies a rotational resistance force to the locking plate 56. . A columnar locking shaft 56A is integrally provided at the lower end of the locking plate 56.

  The heart cam mechanism 54 is provided with a cam plate 58 having a substantially rectangular plate shape as a cam member, and the cam plate 58 is provided integrally with the housing 24 of the moving body 22. A cam path 60 having a substantially annular shape as a cam portion is formed on the front side surface (the side surface of the locking plate 56) of the cam plate 58. The cam path 60 has a rectangular cross section, and the front side of the vehicle. It is open to.

  The vicinity of the lower end of the cam path 60 is a first locking path 62, and the first locking path 62 extends substantially in the rotational radial direction of the moving body 22. A first recess 62A having a triangular cross section as a first locking portion is formed on the upper side surface of the first locking path 62, and the inside of the first recess 62A is open to the lower side. The lower surface of the first locking path 62 is a first inclined surface 62B as a first guide portion, and the first inclined surface 62B is inclined in a direction toward the lower side as it goes inward in the vehicle width direction. Yes. Further, the upper end (bottom) of the first recess 62A is opposed to the first inclined surface 62B in the rotational circumferential direction of the moving body 22.

  An inner portion in the vehicle width direction of the cam path 60 is a first passage path 64, and the first passage path 64 extends substantially in the rotational circumferential direction of the movable body 22. The vicinity of the lower end 64 </ b> A of the first passage 64 is communicated with the first locking path 62, and the lower end 64 </ b> A of the first passage 64 extends downward with respect to the first locking path 62.

  The upper end portion of the cam path 60 is a second locking path 66 that extends substantially in the rotational circumferential direction of the moving body 22 and that has a first passage on the lower portion. The upper end of 64 is connected. A second recess 66A having a semicircular cross section as a second locking portion is formed on the upper side surface of the second locking path 66, and the inside of the second recess 66A is open to the lower side. A lower side surface of the second locking path 66 is a second inclined surface 66B as a second guide portion, and the second inclined surface 66B is inclined in a direction toward the lower side toward the outer side in the vehicle width direction. Yes. The second recess 66A is opposed to the second inclined surface 66B in the rotational circumferential direction of the moving body 22.

  The outer portion of the cam path 60 in the vehicle width direction is a second passage path 68, and the second passage path 68 extends substantially in the rotational circumferential direction of the movable body 22 and has a second locking path at the upper end. The lower portion of 66 is in communication. The vicinity of the lower end 68 </ b> A of the second passageway 68 communicates with the first locking path 62, and the lower end 68 </ b> A of the second passageway 68 extends downward with respect to the first locking path 62. Further, the lower end 68A of the second passage 68 is opposed to the outer end in the vehicle width direction of the first recess 62A in the rotational circumferential direction of the moving body 22.

  The locking shaft 56 </ b> A of the locking plate 56 is inserted into the first locking path 62 of the cam path 60, and the locking shaft 56 </ b> A is driven by the turning force of the moving body 22 to the lower side by the urging force of the torsion coil spring 32. 56A is locked to the upper end of the first recess 62A of the first locking path 62. As a result, the downward movement of the moving body 22 is locked, whereby the moving body 22 is stopped at the storage position and stored in the visor 14.

  Next, the operation of this embodiment will be described.

  In the vehicle door mirror device 10 configured as described above, in the heart cam mechanism 54, the locking shaft 56A of the locking plate 56 is locked to the upper end of the first recess 62A of the first locking path 62 of the cam path 60 in the cam plate 58. Thus, the moving body 22 (including the auxiliary mirror 30) is stopped at the storage position and stored in the visor 14.

  When the automatic transmission 50 is set to the reverse range (reverse range) and the sensor 52 detects an obstacle on the vehicle rear side and the lower side of the vehicle door mirror device 10 (first opportunity), the moving mechanism 34 In FIG. 5, the current is supplied to the motor 36 under the control of the control device 38, and the motor 36 is rotationally driven in one direction, whereby the output shaft 36A of the motor 36, the worm 40, the helical gear 42, the rotating shaft 44, and the pinion 46. And the spa 48 is rotated in one direction, and the moving body 22 is rotated upward (one side) against the urging force of the torsion coil spring 32.

  Therefore, the locking shaft 56A is brought into contact with the first inclined surface 62B of the first locking path 62 and is moved (guided) in the vehicle width direction by the first inclined surface 62B. By being locked to the lower end 64 </ b> A of the first passage 64, the upward rotation of the moving body 22 is locked. As a result, the rotation of the output shaft 36A of the motor 36, the worm 40, the helical gear 42, the rotating shaft 44, the pinion 46 and the spa 48 in one direction is stopped, and the current supplied to the motor 36 is rapidly increased. When the detection unit of the control device 38 detects a sudden increase in the current, the supply of current to the motor 36 is stopped by the control of the control device 38, and the rotational drive in one direction of the motor 36 is stopped. The

  Thereafter, the output shaft 36A, the worm 40, the helical gear 42, the rotating shaft 44, the pinion 46 and the spa 48 of the motor 36 are rotated in the other direction by the urging force of the torsion coil spring 32, while the moving body 22 is moved downward (others). The locking shaft 56 </ b> A is moved (passed) upward through the first passage 64 by moving the storage shaft 56 beyond the storage position to the second concave portion of the second locking passage 66 of the cam path 60. 66A. As a result, the moving body 22 is stopped at the unfolded position and unfolded from the visor 14 downward (may be obliquely downward in the front of the vehicle or obliquely downward in the rear of the vehicle) (see the solid line in FIG. 1).

  Therefore, the auxiliary mirror 30 is exposed to the lower side of the visor 14 so that the occupant can visually recognize the rear side and the lower side (especially the obstacle and its surroundings) of the vehicle door mirror device 10 by the auxiliary mirror 30. Thereby, while preventing the change of the occupant's viewable range by the mirror 18, the occupant's viewable range can be expanded by the auxiliary mirror 30, so that the occupant can assist without changing the line of sight when the vehicle moves backward. The rear side and the lower side of the vehicle door mirror device 10 can be noted with the mirror 30.

  When the automatic transmission 50 is set to a range other than the reverse range and when the sensor 52 no longer detects an obstacle on the rear side and the lower side of the vehicle door mirror device 10 (second opportunity), the moving mechanism 34 The current is supplied to the motor 36 under the control of the control device 38, and the motor 36 is rotationally driven in one direction, so that the output shaft 36A of the motor 36, the worm 40, the helical gear 42, the rotating shaft 44, the pinion 46, and The spa 48 is rotated in one direction, and the moving body 22 is rotated upward against the urging force of the torsion coil spring 32.

  Therefore, the locking shaft 56A is brought into contact with the second inclined surface 66B of the second locking path 66 and is moved (guided) outward in the vehicle width direction by the second inclined surface 66B, so that the second passage path By moving (passing) 68 downward, the locking shaft 56A is locked to the lower end 68A of the second passage 68 after the movable body 22 is rotated upward beyond the storage position. The upward rotation of the moving body 22 is locked. As a result, the rotation of the output shaft 36A of the motor 36, the worm 40, the helical gear 42, the rotating shaft 44, the pinion 46 and the spa 48 in one direction is stopped, and the current supplied to the motor 36 is rapidly increased. When the detection unit of the control device 38 detects a sudden increase in the current, the supply of current to the motor 36 is stopped by the control of the control device 38, and the rotational drive in one direction of the motor 36 is stopped. The

  Thereafter, the output shaft 36A, the worm 40, the helical gear 42, the rotating shaft 44, the pinion 46 and the spa 48 of the motor 36 are rotated in the other direction by the urging force of the torsion coil spring 32, while the moving body 22 rotates downward. By being moved, the locking shaft 56A comes into contact with the first recess 62A of the first locking path 62 and is moved (guided) inward in the vehicle width direction by the first recess 62A. Locked to the upper end of 62A. As a result, the moving body 22 is stopped at the storage position and stored in the visor 14 (see the two-dot chain line in FIG. 1).

  By the way, in this embodiment, when the motor 36 is rotationally driven in one direction, the motor 36, the worm 40, the helical gear 42, and the rotating shaft 44 are compared to when the motor 36 is rotationally driven in the other direction. The operation sound of the pinion 46 and the spa 48 is preferably configured as a sound that produces the operation of the moving body 22 or a sound that does not disturb the occupant.

  Here, as described above, since the heart cam mechanism 54 can stop the moving body 22 at the deployed position and the retracted position, the moving mechanism 34 drives the motor 36 to rotate in only one direction so that the moving body 22 is moved upward only. Even when rotating, the movable body 22 can be unfolded and stored.

  For this reason, the operation sound of the moving mechanism 34 can always be made into the operation sound of the motor 36, the worm 40, the helical gear 42, the rotating shaft 44, the pinion 46, and the spa 48 by the rotation drive of the motor 36 in one direction. The sound that produces the action of the body 22 or the sound that does not disturb the occupant can be obtained. Accordingly, it is possible to prevent the occupant from feeling uncomfortable operation sounds of the motor 36, the worm 40, the helical gear 42, the rotating shaft 44, the pinion 46 and the spa 48 due to the rotational drive of the motor 36 in the other direction. It can suppress that a passenger | crew feels an operation sound unpleasant.

  In addition, the detection unit of the control device 38 that detects the current supplied to the motor 36 to stop the rotational drive of the motor 36 can only be used to stop the rotational drive of the motor 36 in one direction. It is possible to eliminate the need for stopping the rotational drive of the motor 36 in the other direction. Thereby, the structure of the control device 38 can be simplified, and the stop control of the rotation drive of the motor 36 can be simplified.

  Further, in the moving mechanism 34, when the moving body 22 is rotated downward by the biasing force of the torsion coil spring 32, the helical gear 42 is rotated, whereby the worm 40 is rotated. For this reason, even when the gear mechanism of the moving mechanism 34 includes the worm 40 and the helical gear 42 as in the present embodiment, the torsion coil spring 32 is attached without the moving mechanism 34 moving the moving body 22 downward. The moving body 22 can be moved downward by the force.

  Further, the worm 40 is a plurality of worms. For this reason, the larger the number of worms 40, the greater the rotation speed of the worm wheel due to the rotation of the worm 40. The moving mechanism 34 rotates the motor 36 in one direction to rotate the movable body 22 upward. The speed can be increased. Accordingly, it is possible to suppress an unnecessarily long time for the moving body 22 to be deployed from the visor 14 and a time for the moving body 22 to be stored in the visor 14. In particular, since the time required for the moving body 22 to be deployed from the visor 14 can be prevented from being unnecessarily long, the occupant can visually recognize the rear side and the lower side of the vehicle door mirror device 10 with the auxiliary mirror 30 at an early stage.

  Moreover, when the moving body 22 is rotated downward by the urging force of the torsion coil spring 32 (when the worm 40 is rotated by rotating the helical gear 42), the number of worms 40 is large. As the advance angle γ of the worm 40 is smaller, the worm 40 applies a larger rotational resistance force to the helical gear 42, so that the output shaft 36A of the motor 36, the worm 40, the helical gear 42, the rotating shaft 44, the pinion The rotational speed of 46 and the spa 48 in the other direction can be reduced, and the rotational speed of the moving body 22 to the lower side can be reduced. As a result, the occupant can feel the rotational movement of the moving body 22 to the lower side by the urging force of the torsion coil spring 32, and the vehicle door mirror device 10 can be given a high-class feeling.

  Further, unlike the case where the gear mechanism of the moving mechanism 34 does not have the worm 40 and the helical gear 42 (for example, only the spur gear is configured), even if the gear mechanism is downsized, the smaller the number of the worm 40, As the advance angle γ of the worm 40 is smaller, the reduction ratio of the gear mechanism can be increased by the worm 40 and the helical gear 42. Thereby, the moving mechanism 34 can be reduced in size, and the driving force for the moving mechanism 34 to rotate the moving body 22 can be increased.

  Further, the moving body 22 is deployed only when the automatic transmission 50 is set to the reverse range and when the sensor 52 detects an obstacle on the rear side and the lower side of the vehicle door mirror device 10. For this reason, normally, the moving body 22 can be stored in the visor 14, and it can suppress that the appearance of the vehicle door mirror device 10 deteriorates by the moving body 22.

  Furthermore, even if the moving mechanism 34 breaks down, the moving body 22 can be stored in the visor 14 by manually rotating the moving body 22 in place of the moving mechanism 34, and the moving body 22 can be stored in the visor. 14 can be developed. For this reason, it is possible to prevent the state in which the moving body 22 is stored in the visor 14 and the state in which the moving body 22 is deployed from the visor 14 from being maintained.

  In this embodiment, the locking plate 56 is rotatably provided with respect to the cam plate 58 that cannot be rotated. However, the cam plate 58 may be provided so as to be rotatable with respect to the locking plate 56 that cannot be rotated.

  Furthermore, in this embodiment, the locking plate 56 is provided on the bracket 20 side, and the cam plate 58 is provided on the moving body 22 side. However, the locking plate 56 may be provided on the bracket 20 side and the cam plate 58 may be provided on the moving body 22 side.

  In the present embodiment, the moving mechanism 34 rotates the moving body 22 upward, and rotates the moving body 22 downward by the urging force of the torsion coil spring 32. However, the moving mechanism 34 may rotate the moving body 22 downward and the moving body 22 may be rotated upward by the urging force of the torsion coil spring 32.

  Furthermore, in this embodiment, the moving body 22 is rotated to the other side (downward) by the urging force of the torsion coil spring 32. However, the moving body 22 may be rotated to the other side by other moving means (for example, the weight of the moving body 22).

  Further, in the present embodiment, the moving body 22 is deployed only when the automatic transmission 50 is set to the reverse range and when the sensor 52 detects an obstacle on the rear side and the lower side of the vehicle door mirror device 10. It was. However, the moving body 22 may be deployed only when the automatic transmission 50 is set to the reverse range or only when the sensor 52 detects an obstacle on the vehicle rear side and the lower side of the vehicle door mirror device 10.
