Description

  The present invention relates to a vehicle mirror device in which a mirror is stored by rotating a rotating body with respect to a support.

  In the vehicle mirror device described in Patent Document 1 below, a mirror body (including a mirror) is rotatably supported on a base, and a collision load (large load) is applied to the mirror body in the standing position from the rear side of the vehicle. When an input is made, the mirror main body abutment portion (inclined surface) rides on the base abutment portion (inclined surface), thereby allowing rotation of the mirror main body relative to the base toward the vehicle front side.

  By the way, in such a vehicle mirror device, when the mirror main body is rotated from the standing position to the front side of the vehicle or when the mirror main body is rotated from the standing position to the rear side of the vehicle, the mirror is attached to the contact portion of the base. When the abutting portion of the main body comes into contact, even if a collision load is input to the mirror main body, the rotation of the mirror main body with respect to the base may be prohibited (not allowed).

  Here, in such a case, it is preferable that damage to at least one abutting portion (particularly the abutting portion on the low strength side) of the base and the mirror main body can be suppressed.

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

  In the vehicle door mirror device 10 having the above-described configuration, the main body 30 is integrated with the driving body 24 by the drive of the storage device 14 or the input of an external force to the main body 30 (particularly the visor 32) (indicated by a solid line in FIG. 1). The main body 30 (including the mirror 46) is moved to the retracted position (the position indicated by the two-dot chain line in FIG. 1) by rotating from the unfolded position shown in the figure to the retracted direction (the rear side of the vehicle and the inner side in the vehicle width direction). Arranged and stored (post-stored).

  On the other hand, when the storage device 14 is driven or an external force is input to the main body portion 30 (particularly the visor 32), the main body portion 30 rotates together with the drive body 24 from the retracted position in the forward direction (vehicle front side and vehicle width direction outer side). By being moved, the main body 30 (including the mirror 46) is returned to the standing position and is raised.

  Further, when the storage device 14 is driven or an external force is input to the main body 30 (particularly the visor 32), the main body 30 is integrated with the drive body 24 from the standing position (deployed position indicated by a solid line in FIG. 1) from the forward direction ( The main body 30 (including the mirror 46) is arranged at the forward position (position indicated by a one-dot chain line in FIG. 1) by being turned to the front side of the vehicle and the inner side in the vehicle width direction. Stored).

  On the other hand, when the storage device 14 is driven or an external force is input to the main body 30 (particularly the visor 32), the main body 30 is integrated with the drive body 24 from the forward position to the storage direction (the vehicle rear side and the vehicle width direction outer side). By rotating, the main body 30 (including the mirror 46) is returned to the standing position and is raised.

  By the way, when the main body 30 is disposed at the storage position, it is provided on the first prohibiting surface 20A of the prohibiting projection 20 provided on the stay 12 (supporting projection 12A) and the storage device 14 (case 26 of the driving body 24). The first contact surface 28A of the contact protrusion 28 thus formed is brought into surface contact (see the two-dot chain line in FIGS. 1 and 2). For this reason, even when a collision load (large load) in the retracting direction (inward in the vehicle width direction) is input to the main body 30, rotation of the main body 30 in the retracting direction is prohibited (not allowed). In this case, a vertical load S1 is applied from the first prohibited surface 20A to the first contact surface 28A, a vertical load S2 is applied from the first contact surface 28A to the first prohibited surface 20A, and is perpendicular to the vertical load S1. The load S2 is made in the opposite direction to each other and has the same size (see FIG. 2).

  Further, when the main body portion 30 is disposed at the forward position, the second prohibiting surface 20B of the prohibiting protrusion 20 provided on the stay 12 (supporting protrusion 12A) and the storage device 14 (the case 26 of the driving body 24) are provided. The second contact surface 28B of the provided contact protrusion 28 is brought into surface contact (see the one-dot chain line in FIGS. 1 and 2). For this reason, even when a collision load (large load) in the forward direction (inward in the vehicle width direction) is input to the main body 30, rotation of the main body 30 in the forward direction is prohibited (not allowed). . In this case, a vertical load T1 is applied from the second prohibited surface 20B to the second contact surface 28B, a vertical load T2 is applied from the second contact surface 28B to the second prohibited surface 20B, and is perpendicular to the vertical load T1. The load T2 is made in the opposite direction to each other and has the same size (see FIG. 2).

  Here, the first prohibited surface 20A, the first contact surface 28A, and the second prohibited surface with respect to the rotational radial direction of the main body 30 (the rotational radial direction of the driving body 24 and the radial direction of the support shaft 22 of the stand 16). 20B and the second contact surface 28B are inclined.

  For this reason, when the rotation of the main body 30 arranged at the storage position in the storage direction is prohibited, the contact area between the first prohibition surface 20A and the first contact surface 28A can be increased, and the first prohibition is performed. The stress acting on the surface 20A and the first contact surface 28A can be reduced. Thereby, damage and abrasion of the prohibition protrusion 20 (first prohibition surface 20A) and the contact protrusion 28 (first contact surface 28A) can be suppressed.

  Furthermore, when the rotation of the main body 30 disposed at the forward position in the forward direction is prohibited, the contact area between the second prohibited surface 20B and the second contact surface 28B can be increased, and the second The stress acting on the forbidden surface 20B and the second contact surface 28B can be reduced. Thereby, damage and abrasion of the prohibition protrusion 20 (second prohibition surface 20B) and the contact protrusion 28 (second contact surface 28B) can be suppressed.

  Further, the first prohibiting surface 20A and the first contact surface 28A and the second prohibiting surface 20B and the second contact surface 28B increase from the contact protrusion 28 on the lower strength side toward the inner side in the rotational radial direction of the main body portion 30. It is inclined in the direction toward the forbidden protrusion 20 on the side.

  For this reason, the low-strength contact protrusion 28 protrudes toward the high-strength prohibition protrusion 20 as it goes inward in the rotational radial direction of the main body 30 to increase the strength.

  Further, when the rotation of the main body 30 arranged in the storage position is prohibited in the storage direction and the rotation of the main body 30 arranged in the forward movement position in the forward movement direction is prohibited, The main body portion 30 is moved from the prohibiting protrusion 20 on the high-strength side to the contact protrusion 28 on the low-strength side with respect to the rotating circumferential direction of the main body 30 (the rotating circumferential direction of the driving body 24 and the circumferential direction of the support shaft 22 of the stand 16). Vertical loads S1 and T1 inward in the rotational radial direction are input.

  In this way, the strength of the contact protrusion 28 on the low strength side is increased as it goes inward in the rotational radial direction of the main body portion 30, and when the rotation of the main body portion 30 is prohibited, Vertical loads S1 and T1 are input to the contact protrusions 28 on the low strength side inwardly in the rotational radial direction of the main body 30 with respect to the rotational circumferential direction of the main body 30. Thereby, damage and wear of the low-strength contact protrusion 28 that is easily damaged and worn can be further suppressed, and the prohibition protrusion 20 (first prohibition surface 20A and second prohibition surface 20B) and contact protrusion 28 (first contact surface 28A). And damage and wear of the second contact surface 28B) can be further suppressed.

  As described above, the size of the prohibition protrusion 20 and the contact protrusion 28 (particularly, the low-strength contact protrusion 28) in the main body 30 rotation radial direction and the main body 30 rotation circumferential direction can be reduced, and space efficiency can be improved (prohibition protrusion). 20 and the contact projection 28 can be reduced in space), and the weight and cost can be reduced.

  In the present embodiment, the first prohibiting surface 20A, the first contact surface 28A, the second prohibiting surface 20B, and the second contact surface 28B are inclined with respect to the rotational radial direction of the main body 30. However, the first prohibiting surface 20A and the first contact surface 28A and the second prohibiting surface 20B and the second contact surface 28B are at least one of the rotational radial direction and the rotational axis direction (vertical direction) of the main body 30. Just tilt it.

  Furthermore, in the present embodiment, the first forbidden surface 20A and the first contact surface 28A, the second forbidden surface 20B and the second contact surface 28B are planar.

  However, at least one of the first prohibited surface 20A and the first contact surface 28A and the second prohibited surface 20B and the second contact surface 28B may be curved.

  When the first prohibiting surface 20A and the first contact surface 28A are curved, the first prohibiting surface 20A and the first prohibiting surface 20A and the first prohibiting surface 20A when the rotation of the main body 30 disposed at the storing position in the storing direction is prohibited. The contact area with the contact surface 28A can be further increased, and the stress acting on the first prohibited surface 20A and the first contact surface 28A can be further decreased. Thereby, damage and abrasion of the prohibition protrusion 20 (first prohibition surface 20A) and the contact protrusion 28 (first contact surface 28A) can be further suppressed.

  When the second forbidden surface 20B and the second contact surface 28B are curved, the rotation of the main body portion 30 arranged at the forward-turning position in the forward-falling direction is prohibited. The contact area with the second contact surface 28B can be further increased, and the stress acting on the second forbidden surface 20B and the second contact surface 28B can be further decreased. Thereby, damage and abrasion of the prohibition protrusion 20 (second prohibition surface 20B) and the contact protrusion 28 (second contact surface 28B) can be further suppressed.

  Further, in the present embodiment, the prohibition protrusion 20 is provided on the stay 12 and the contact protrusion 28 is provided on the driving body 24. However, the prohibition protrusion 20 may be provided on the stand 16, and the contact protrusion 28 may be provided on the visor 32, for example.

  Furthermore, in the present embodiment, the contact protrusion 28 has a lower strength than the prohibition protrusion 20. However, the strength of the prohibition protrusion 20 may be made lower than that of the contact protrusion 28.

  In addition, in the present embodiment, there is a difference in strength between the prohibition protrusion 20 and the contact protrusion 28 due to the difference between the installation state of the prohibition protrusion 20 on the stay 12 and the installation state of the contact protrusion 28 on the driving body 24. Yes. However, a difference in strength between the prohibition protrusion 20 and the contact protrusion 28 may occur due to a difference in material (for example, metal and resin) between the prohibition protrusion 20 and the contact protrusion 28.

  In the present embodiment, the vehicle mirror device of the present invention is applied to the vehicle door mirror device 10. However, the vehicle mirror device of the present invention may be applied to another vehicle outer mirror device (for example, a vehicle fender mirror device) outside the vehicle or a vehicle inner mirror device inside the vehicle.
