Description

  The present invention relates to a vehicle mirror device.

  In a vehicle door mirror device, a case to which a mirror for rearward visual recognition is attached is displaced in an axial direction with respect to a support shaft of a stand attached to the vehicle body, so that the mirror and the case are in a vehicle body rather than a normal use position. There is a configuration that can be rotated forward (so-called “front folding”) (see, for example, Patent Document 1).

However, when the case and the mirror are tilted forward, that is, when the case is displaced axially with respect to the support shaft, the side wall of the case that covers the sliding portion between the case and the stand provided around the support shaft Is also displaced in the axial direction of the support shaft, so that a gap is formed between the side wall and the stand. For this reason, when the case and the mirror are exposed to rain or the like in a state where the case and the mirror are tilted forward, water enters the sliding portion through the gap. For this reason, a sufficient amount of grease is required for the sliding portion so as not to be affected by the infiltrated water.

  Further, a pair of fitting holes 43 are formed in the bottom wall 30 </ b> A of the case body 30 on the outside of the case body 30. The pair of fitting holes 43 are formed between the adjacent ribs 41, and the bottom surfaces of the pair of fitting holes 43 are formed by the walls spanning the adjacent ribs 41. The pair of fitting holes 43 are formed on opposite sides of the downward projecting portion 34B and correspond to a detent plate 76 described later.

  Furthermore, the case body 30 has a hanging wall 30C formed around the downward projecting portion 34B. The hanging wall 30C is formed concentrically with the downward projecting portion 34B, that is, the support shaft 26, and corresponds to a standing wall 64 described later.

  The case 28 having the above configuration is connected to the visor 14 via a frame (not shown), and the door mirror main body 12 is integrally rotatable with the case 28 about the support shaft 26. Thereby, the door mirror main body 12 and the case 28 can be rotated between the storage position shown in FIG. 6 and the deployed position shown in FIG. 7, and as shown in FIG. 8, set to the front side of the vehicle body from the deployed position. It is configured to be able to turn to the forward retractable position. That is, the door mirror main body 12 and the case 28 are configured to be able to rotate in a rotation range between the retracted position and the deployed position and a forward rotation range between the deployed position and the front retractable position.

  When the case 28 reaches the retracted position, the rotation prevention part 40 protruding from the fixing part 24 of the stand 22 is formed on the inner peripheral part of the hanging wall 30C of the case body 30. , The rotation of the case 28 is prevented, and when the case 28 reaches the front-falling position, the rotation prevention portion 40 is formed on the inner peripheral portion of the hanging wall 30C. By contacting the portion 44, the rotation of the case 28 is prevented.

  On the other hand, as shown in FIG. 3, a motor 46 is housed and fixed inside the case 28. This motor 46 is driven by operating a switch (not shown) provided in the vehicle to rotate the output shaft 48, and an external force acting against the rotation of the output shaft 48 acts to set the current value of the supply current to a predetermined value. When the value exceeds the threshold value, that is, when a lock current flows, power supply is cut off by a control circuit (not shown) provided in the vehicle.

  A worm 50 is attached to the output shaft 48 of the motor 46, and a helical gear 52 is engaged with the worm 50. The helical gear 52 is integrally provided with a shaft worm 54, and the helical gear 52 and the shaft worm 54 always rotate integrally.

  A cylindrical gear plate 56 is provided inside the case 28. The gear plate 56 is rotatably supported by the support shaft 26, and one end in the axial direction is in contact with the tip of the upward projecting portion 34 </ b> A, that is, the other end in the axial direction of the bearing portion 34. Note that grease is applied to the tip of the upper protrusion 34A and one end in the axial direction of the gear plate 56, and this grease is applied to the grease reservoir groove 57 (FIGS. 4 and 9) formed at the tip of the upper protrusion 34A. , See FIG. 13).

  External teeth are formed on the outer periphery of the gear plate 56, and the external teeth mesh with the shaft worm 54. Thereby, when the output shaft 48 rotates integrally with the worm 50 by the driving force of the motor 46, a rotational force is applied to the gear plate 56 via the helical gear 52 and the shaft worm 54.

  A clutch disk 58 is disposed on the opposite side of the bottom wall of the case body 30 via the gear plate 56. The clutch disk 58 is coaxially supported by the support shaft 26 and is not rotatable with respect to the support shaft 26 and is movable in the axial direction. The clutch disc 58 has a convex portion that fits into a concave portion formed in the inner peripheral portion of the gear plate 56, and the clutch disc 58 and the gear plate 56 are only at a predetermined position along the circumferential direction. In meshing engagement.

  Further, a tea washer 60 is disposed on the side opposite to the gear plate 56 via the clutch disk 58. The tea washer 60 is attached to the tip of the support shaft 26 so as not to move in the axial direction.

  Further, a compression coil spring 62 is disposed between the tea washer 60 and the clutch disk 58. The compression coil spring 62 biases the clutch disc 58 in the direction of engagement with the gear plate 56. As a result, the meshing engagement state between the gear plate 56 and the clutch disc 58 is normally maintained, and the relative rotation of the gear plate 56 with respect to the support shaft 26 is restricted.

  The urging force of the compression coil spring 62 acts on the case 28 via the clutch disk 58 and the gear plate 56, and the urging force of the compression coil spring 62 causes one end in the axial direction of the bearing portion 34, that is, the downward projecting portion 34B. The tip of this is pressed against the fixing portion 24 of the stand 22 via the slip washer 38.

  On the other hand, on the fixing portion 24 of the stand 22, a ring-like standing wall 64 that protrudes toward the case 28 is formed concentrically with the support shaft 26 on the radially outer side of the support shaft 26. The standing wall 64 is formed concentrically with the downward projecting portion 34B (bearing portion 34) of the case body 30 described above, and is disposed on the radially outer side of the downward projecting portion 34B. That is, as shown in FIG. 9, the upright wall 64 and the distal end side of the downward projecting portion 34 </ b> B are superposed along the radial direction of the support shaft 26 (direction perpendicular to the rotational axis direction of the case 28). Further, the standing wall 64 is formed concentrically with the hanging wall 30C of the case body 30 described above, and is disposed on the radially inner side of the hanging wall 30C. That is, as shown in FIG. 9, the standing wall 64 and the hanging wall 30 </ b> C are superposed along the radial direction of the support shaft 26.

  At the tip of the standing wall 64, three stand peaks 66, 68, 70 project toward the case 28 side. As shown in FIG. 10, these three stand peaks 66, 68, 70 are formed by being curved along the circumferential direction of the support shaft 26, and are arranged at substantially equal intervals along the circumferential direction of the standing wall 64. . The three stand peaks 66, 68, and 70 are formed in a trapezoidal shape in which both end portions along the circumferential direction of the support shaft 26 are inclined surfaces 72 and 74, respectively. The two stand peaks 68 and 70 are provided on different circles around the support shaft 26. That is, the two stand peaks 68 and 70 are disposed at the same distance from the axis of the support shaft 26, and the one stand peak 66 has a distance from the axis of the support shaft 26 of the stand peaks 68 and 70. Is also located far away.

  Further, a detent plate 76 as a detent member formed in a ring shape between the standing wall 64 of the stand 22 and the bottom wall 30A of the case body 30 and between the hanging wall 30C of the case body 30 and the bearing portion 34. Is arranged.

  As shown in FIG. 11, two steps are formed on the outer peripheral portion of the detent plate 76, and the detent plate 76 has a narrow portion having a narrow radial dimension at a substantially half portion along the circumferential direction. 78, and the remaining substantially half portion along the circumferential direction is a wide portion 80 having a large radial dimension.

  A pair of fitting protrusions 81 are formed on the case 28 side end surfaces of the narrow width portion 78 and the wide width portion 80 toward the case 28 side. The pair of fitting projections 81 are fitted in the pair of fitting holes 43 formed on the bottom wall 30 </ b> A of the case body 30. Accordingly, the detent plate 76 is held by the case body 30 and the relative rotation of the detent plate 76 with respect to the case body 30 is restricted.

  On the other hand, as shown in FIG. 12, one case mountain 82 projects from the end face of the wide portion 80 on the fixed portion 24 side toward the fixed portion 24 toward the outer periphery. In addition, two case peaks 84 and 86 project from the end surface of the narrow portion 78 on the fixed portion 24 side toward the fixed portion 24 side. These three case peaks 82, 84, 86 are arranged at substantially equal intervals along the circumferential direction of the detent plate 76, and both end portions along the circumferential direction of the detent plate 76 are inclined surfaces 88 and 90, respectively. The one case peak 82 formed in the wide part 80 and the two case peaks 84 and 86 formed in the narrow part 78 are centered on the support shaft 26. It is provided on a different circle. The three case peaks 82, 84, and 86 are opposed to the stand peaks 66, 68, and 70, respectively, so that the detent includes the case peaks 82, 84, 86 and the stand peaks 66, 68, 70. Grease is applied to the opposing portion of the plate 76 and the standing wall 64.

  Here, as shown in FIG. 6, in the state where the door mirror main body 12 and the case 28 are located at the retracted position, the three case peaks 82, 84, 86 of the detent plate 76 correspond to the three stand peaks 66, 68 and 70 are separated from each other. Further, when the door mirror main body 12 and the case 28 are located between the retracted position and the deployed position (that is, the rotation range), as shown in FIG. 9, the tip of the hanging wall 30C of the case main body 30 and the stand 22 are fixed. Only a slight gap is formed between the portion 24 and the hanging wall 30 </ b> C is superposed over substantially the entire area of the standing wall 64 in the radial direction.

  On the other hand, as shown in FIG. 7, in the state where the door mirror main body 12 and the case 28 are located at the unfolded position, the three case peaks 82, 84, 86 of the detent plate 76 are changed to the three stand peaks 66, 68 of the stand 22, respectively. , 70 abuts on each inclined surface 72. As a result, the case 28 is restricted from rotating beyond the deployed position to the front retractable position.

  Further, when an external force of a predetermined value or more directed toward the front of the vehicle body is applied to the case 28 located at the unfolded position, the inclined surfaces 88 of the three case peaks 82, 84, 86 of the detent plate 76 are 22 slidably contact with the inclined surfaces 72 of the three stand peaks 66, 68, and 70, a component force is generated on the detent plate 76 in the upward direction, that is, in a direction away from the standing wall 64. For this reason, as shown in FIG. 13, the detent plate 76 is displaced by a predetermined amount together with the case 28 against the urging force of the compression coil spring 62, that is, the other side in the axial direction of the support shaft 26. Case mountains 82, 84, and 86 ride on three stand mountains 66, 68, and 70 of the stand 22, respectively. As a result, the case 28 can be rotated beyond the deployed position, and the case 28 is configured to be rotated to the front retractable position by the external force (see FIG. 8).

  Here, in this door mirror device 10, when the door mirror main body 12 and the case 28 rotate between the retracted position and the deployed position (that is, the rotation range), one end in the axial direction of the bearing portion 34, that is, a downward protrusion. The tip of the portion 34B slides with the slip washer 38, so that the case 28 is supported in the thrust direction.

  On the other hand, when the door mirror body 12 and the case 28 are rotated between the deployed position and the front retractable position (that is, the front rotation range), the case 28 is displaced upward by a predetermined amount as described above. , One end in the axial direction of the bearing portion 34, that is, the tip of the downward projecting portion 34B is separated from the slip washer 38. Instead, each tip of the three case peaks 82, 84, 86 is replaced with three stand peaks 66, 68, The case 28 is configured to be supported in the thrust direction by sliding with the front ends of the 70.

  Further, in this manner, when the case 28 is displaced upward by a predetermined amount, as shown in FIG. 13, the hanging wall 30C of the case body 30 is also displaced upward, and the tip of the hanging wall 30C and the fixing portion 24 of the stand 22 In this state, the hanging wall 30 </ b> C and the standing wall 64 of the stand 22 are superposed along the radial direction of the support shaft 26. Moreover, in this state, the downward projecting portion 34B is also displaced upward. In this state, the tip of the downward projecting portion 34B and the standing wall 64 are superposed along the radial direction of the support shaft. Yes.

  Next, the operation of the present embodiment will be described.

  In the door mirror device 10 configured as described above, when the motor 46 is driven by the operation of a switch (not shown) and the worm 50 is rotated integrally with the output shaft 48, the helical gear 52 meshed with the worm 50 is rotated integrally with the shaft worm 54. Then, a rotational force is applied to the gear plate 56 meshed with the shaft worm 54. The case 28 is rotated by the reaction force of the rotational force. Thereby, the door mirror main body 12 is integrated with the case 28 and is rotated from the deployment position to the storage position or from the storage position to the deployment position. Further, when the door mirror main body 12 and the case 28 are rotated between the retracted position and the deployed position in this way, one end in the axial direction of the bearing portion 34, that is, the tip of the downward projecting portion 34 B slides with the slip washer 38. Thus, the case 28 is supported in the thrust direction.

  When the door mirror body 12 and the case 28 that rotate from the retracted position to the deployed position reach the deployed position, the inclined surfaces 88 of the three case peaks 82, 84, 86 of the detent plate 76 are respectively By contacting the inclined surfaces 72 of the three stand peaks 66, 68, and 70 of the stand 22, the forward rotation of the door mirror body 12 and the case 28 beyond the deployment position is restricted. For this reason, the output shaft 48 of the motor 46 cannot rotate, and the current value of the current flowing through the motor 46 rises to a predetermined threshold value or more. Thereby, the power supply to the motor 46 is cut off by a control circuit (not shown), and the motor 46 is stopped.

  On the other hand, when an external force of a predetermined value or more directed toward the front of the vehicle body is applied to the door mirror main body 12 located at the unfolded position, the three case peaks 82, 84, 86 of the detent plate 76 are changed to the three of the stand 22, respectively. By riding on the stand peaks 66, 68, 70, the case 28 can be rotated beyond the deployed position, and the case 28 and the door mirror main body 12 are displaced by a predetermined amount upward, that is, to the other side in the axial direction of the support shaft 26. In this state, it is rotated to the front retractable position by the external force. Further, when the door mirror main body 12 and the case 28 are rotated between the deployed position and the front retractable position, that is, in the front rotation range, the tip ends of the three case peaks 82, 84, 86 have three The case 28 is supported in the thrust direction by sliding with the tips of the stand peaks 66, 68, 70.

  Here, in the door mirror device 10, the case 28 and the door mirror main body 12 are disposed in the forward rotation range, that is, the case 28 and the door mirror main body 12 are displaced by a predetermined amount with respect to the support shaft 26 in the other axial direction. Even in the state, the hanging wall 30 </ b> C of the case body 30 is overlapped on the radially outer side of the standing wall 64 of the stand 22. Therefore, for example, even if the door mirror device 10 is exposed to rain or the like in this state, sliding between the stand peaks 66, 68, 70 and the case peaks 82, 84, 86 provided on the radially inner side of the hanging wall 30C. Water can be prevented from entering the portion and the sliding portion between the bearing portion 34 and the slip washer 38. Thereby, for example, the amount of grease applied to each of the sliding portions can be reduced.

  Moreover, in the door mirror device 10 according to the present embodiment, even when the case 28 and the door mirror main body 12 are displaced by a predetermined amount from the support shaft 26 to the other side in the axial direction, the tip of the downward projecting portion 34B and the standing wall 64 Are superposed along the radial direction of the support shaft 26. Therefore, even if water enters the radial inner side of the hanging wall 30C, water enters the sliding portion between the downward projecting portion 34B and the slip washer 38 provided between the standing wall 64 and the support shaft 26. Can be suppressed.

  Further, in the door mirror device 10 according to the present embodiment, the grease applied to the tip of the downward projecting portion 34B and the slip washer 38 is held in the grease reservoir groove 39 formed at the tip of the downward projecting portion 34B and protrudes upward. The grease applied to the tip of the portion 34A and one end in the axial direction of the gear plate 56 is held in a grease retaining groove 57 formed at the tip of the upward projecting portion 34A. Therefore, the case 28 can be smoothly rotated with respect to the stand 22 even after the door mirror device 10 is used for a long period of time.

  Further, in the door mirror device 10 according to the present embodiment, since the plurality of ribs 41 are radially extended from the bearing portion 34 on the opposite side of the bottom wall 30A of the case body 30 from the detent plate 76, these The bearing portion 34 can be reinforced by the plurality of ribs 41. Moreover, since the pair of fitting holes 43 and the pair of fitting projections 81 that restrict relative rotation of the detent plate 76 with respect to the case 28 are arranged between the adjacent ribs 41, the height dimension of the standing wall 64 Even when the overlapping amount of the standing wall 64 and the hanging wall 30 </ b> C is sufficiently secured due to the increase, the increase in the size of the case body 30 along the axial direction of the support shaft 26 can be suppressed.

  In the door mirror device 10 according to the above-described embodiment, the stand 22 includes a support shaft 26 as a rotation support portion, and the case 28 includes a bearing portion as a rotation support portion. Not only this but the structure as which the axis | shaft as a to-be-rotated support part provided in the case may be rotatably supported by the bearing hole as a rotation support part provided in the stand may be sufficient.
