Description

  The present invention relates to a vehicle side mirror attached to, for example, an automobile.

  Conventionally, a side mirror for rearward confirmation is attached to a side portion of a vehicle. The side mirror includes a base unit fixed to the vehicle, a mirror housing that holds the mirror, and a storage unit that rotatably connects the mirror housing to the base unit to switch the mirror housing between a use state and a storage state. And.

  For example, as disclosed in Patent Document 1, the storage unit includes a base side member fixed to the base portion, and a case fixed to the mirror housing and accommodating a motor and the like. The base side member is provided with a support shaft, and a plurality of fixed-side convex portions are provided around the support shaft of the base side member at intervals in the circumferential direction. On the other hand, the case is provided with a plurality of movable side convex portions.

  The case is biased by a spring in a direction in contact with the base-side member, and the fixed-side convex portion and the movable-side convex portion of the base-side member are engaged when in the retracted state and when in use. When the mirror housing is moved by hand from this state, for example, the movable side convex part on the case side moves over the fixed side convex part of the base side member against the biasing force of the spring. It can be turned.

  In Patent Document 1, the fixed-side convex portion of the base side member is made of metal, and the movable-side convex portion of the case is made of resin, and the movable-side convex portion of the case is covered with a metal plate, thereby fixing the fixed side. Damage due to sliding contact with the convex portion is prevented.

  By the way, there is a demand to make the base side member made of resin in order to reduce the weight of the side mirror. In this case, since the fixed convex portion of the base side member is also made of resin, there is a concern that the base side member may be damaged during sliding contact with the movable convex portion of the case. Therefore, it is conceivable that the fixed-side convex portion of the base side member is covered with a metal plate in the same manner as the case-side movable-side convex portion.

  However, in this case, as described above, the case is biased by the spring in the direction in contact with the base side member, so that the movable side plate on the case side strongly contacts the fixed side plate of the base side member. As a result, the movable plate and the fixed plate may be fixed. When both plates are fixed, when the mirror housing starts to rotate by hand, when the movable plate on the case side starts to move, the fixed plate on the base member side that is fixed to the case housing is connected in the same direction. It is elastically deformed so as to lift from the fixed convex part. When the fixed side plate is elastically deformed to some extent, the fixed side plate is moved away from the movable side plate due to the restoring force of the fixed side plate, and the original shape is vigorously restored. There is a problem that abnormal noise is generated when the stationary plate is restored and hits the stationary convex portion.

Moreover, the fact that the stationary plate is deformed to float from the fixed-side protrusion is that the fixed side plate is forcibly deformed, the fixed side plate and such deformation is repeated many times May crack.

  The present invention has been made in view of the above points, and the object of the present invention is to provide resin convex portions on both the base member and the mirror housing, and to cover these convex portions with protective plates, respectively. In this case, by preventing the plates from sticking to each other, it is possible to suppress the generation of abnormal noise during rotation and to suppress cracking of the plates.

  In order to achieve the above object, in the present invention, the two plates are prevented from sticking by being brought into line contact.

According to a first aspect of the present invention, a base portion attached to a vehicle, a mirror housing to which a mirror is attached, and the mirror housing are rotatably connected to the base portion, and the mirror housing is switched between a storage state and a use state. In the vehicle side mirror including the storage unit, the storage unit is fixed to the base portion, and is fixed to the mirror housing and is rotatably connected to the fixing member. A movable member made of resin and a biasing member for biasing the movable member in a direction approaching the rotational axis direction with respect to the fixed member, and a surface of the fixed member facing the movable member A fixed-side convex portion protruding in the rotation axis direction is formed, and a fixed-side plate for covering and protecting the fixed-side convex portion is attached. The surface facing the fixing member in the member, the movable-side protrusion protruding to the rotation axis direction is formed, the movable side plate for covering and protecting the movable-side protrusion is mounted, movable side The plate is provided with a projecting piece that engages with the movable member and suppresses the displacement of the movable side plate with respect to the movable member, and a portion that covers the side surface of the movable convex portion of the movable side plate is attached to the plate. Engage with the portion of the fixed-side plate that covers the side surface of the fixed-side convex portion by the force to prevent the mirror housing from rotating, and on the fixed-side convex portion against the biasing force. The mirror housing is configured to move and allow rotation of the mirror housing, the contact surface of the fixed plate is a flat surface that covers the side surface of the fixed convex portion, and the contact surface of the movable plate is Up It is composed of a flat surface that covers the side surface of the movable-side convex portion, and the degree of inclination of the contact surface of the fixed-side plate with respect to the rotation axis when viewed from the radial direction of the rotation-axis is the rotation of the contact surface of the movable-side plate. It is set so that it is steeper than the inclination with respect to the axis, and the contact surface of the fixed plate with the movable plate and the contact surface of the movable plate with the fixed plate are in line contact. It is characterized by being.

  According to this configuration, the weight of the side mirror can be reduced by making the fixed side convex portion of the fixed member fixed to the base portion and the movable side convex portion of the movable member fixed to the mirror housing from resin. In this case, since the fixed-side convex portion is protected by the fixed-side plate and the movable-side convex portion is protected by the movable-side plate, damage to both convex portions is suppressed.

  Since both the contact surfaces of the fixed side plate and the movable side plate are in line contact with each other, even if both contact surfaces are pressed against each other by the urging force of the urging member, it is difficult to adhere.

  As a result, when the movable plate moves when the mirror housing is rotated, the fixed plate is not moved by the movable plate, and the movable plate is prevented from floating from the movable convex portion. In addition, excessive deformation of the movable side plate is suppressed.

Further , by making the contact surfaces of the fixed side plate and the movable side plate flat, it is possible to easily manufacture both plates. In this case, it is possible to make it difficult to fix both contact surfaces.

In addition , since the contact surface of the fixed side plate has a steep inclination, when the mirror housing is rotated, it becomes difficult for the contact surface of the movable side plate to get over the contact surface of the fixed side plate, and the state of the mirror housing is unexpectedly changed. It becomes possible to suppress switching. In addition, it is possible to suppress the occurrence of abnormal noise.

  According to the first aspect of the present invention, both the fixed-side convex portion of the fixed member fixed to the base portion and the movable-side convex portion of the movable member fixed to the mirror housing are made of resin, while reducing the weight of the side mirror. Damage to the part can be suppressed. The contact surfaces of the fixed side plate and the movable side plate are brought into line contact with each other, so that the both contact surfaces are difficult to be fixed, thereby preventing the generation of noise during the rotation of the mirror housing and the fixed side plate. Can be prevented from cracking.

In addition , since the contact surfaces of the fixed side plate and the movable side plate are configured as flat surfaces, manufacturing can be easily performed. In this case, the rotation axis between the contact surface of the fixed side plate and the contact surface of the movable side plate Since the inclination angles with respect to each other are made different from each other, it is possible to make it difficult to fix the both contact surfaces and to suppress the generation of abnormal noise and the cracking of the stationary side plate.

In addition , since the inclination of the contact surface of the stationary plate with respect to the rotation axis is made steeper than the inclination of the contact surface of the movable plate with respect to the rotation axis, the state of the mirror housing is suppressed while suppressing the generation of abnormal noise. It can suppress that it switches unexpectedly.

Above the mounting seat 40a of the fixed shaft 40, a small diameter cylindrical portion 40b extending upward is formed. The cylindrical portion 40b passes through a through hole 41a (shown in FIG. 8) formed in the bottom wall portion of the drive case 41, and is accommodated in the drive case 41 as shown in FIGS. .

  The bottom wall portion of the drive case 41 is disposed so as to face the upper surface of the mounting seat 40a. The drive case 41 is supported so as to be rotatable with respect to the cylindrical portion 40b. The center line of the cylindrical portion 40b is the rotation axis X (shown in FIG. 4) of the mirror housing 4.

A drive mechanism for driving the mirror housing 4 is accommodated in the drive case 41. The drive mechanism includes a drive motor 46 provided with a drive gear 45 composed of a worm gear on the output shaft, and a rotary shaft 48 provided with a driven gear 47 meshing with the drive gear 45 as shown in FIGS. And a sun gear 49 provided at the lower end of the cylindrical portion 40 b of the fixed shaft 40, and a planetary gear 52 formed of a worm gear that meshes with the sun gear 49 is provided at the tip of the rotating shaft 48. The output of the drive motor 46 input to the drive gear 45 is transmitted to the planetary gear 52 via the driven gear 47. The drive motor 46 is controlled by a control device (not shown).

Further, as shown in FIG. 5, a biasing member 54 made of a coil spring that biases the sun gear 49 and the drive case 41 downward is housed inside the drive case 41 . The urging member 54 is disposed so as to surround the cylindrical portion 40 b of the fixed shaft 40.

  A plurality of teeth 58 (only one is shown in FIG. 5) are integrally formed on the outer peripheral surface of the cylindrical portion 40b at intervals in the circumferential direction. The teeth 58 become thinner toward the upper end.

  As shown in FIG. 7, a pair of fixed-side convex portions 57 are integrally formed on the upper surface of the mounting seat 40 a of the fixed shaft 40 (the surface facing the bottom wall portion of the drive case 41) at intervals in the circumferential direction. ing. These fixed-side convex portions 57 and 57 have the same shape and are long in the circumferential direction. As shown also in FIG. 12, both side surfaces 57a, 57a in the longitudinal direction of each fixed-side convex portion 57 are configured as flat surfaces inclined with respect to the rotation axis X so as to approach each other upward. . That is, the dimension in the longitudinal direction of the fixed-side convex portion 57 becomes shorter as it goes upward (as it approaches the distal end surface 57b in the protruding direction). Further, the front end surface 57b is configured to be flat and extend in the circumferential direction of the rotation axis X.

  As shown in FIG. 4, a fixed side plate 60 is provided on the upper surface of the mounting seat 40a. The fixed side plate 60 covers and protects the fixed side convex portions 57, 57, and is a press-formed product of a steel plate.

  As shown in FIGS. 9 and 10, the shape of the fixed side plate 60 is a ring shape that extends along the upper surface of the mounting seat 40 a of the fixed shaft 40. At two locations in the circumferential direction of the fixed side plate 60, extending plate portions 61, 61 projecting radially outward and extending in the circumferential direction are formed, and the fixed side convex portion 57 is formed by each extending plate portion 61. It comes to cover. As shown in FIG. 11, the extension plate portion 61 includes flat contact surfaces 61 a and 61 a that extend along the side surface 57 a of the fixed-side convex portion 57 and are inclined in the same manner as the side surface 57 a, and the fixed-side convex portion. And a flat surface 61b extending along the front end surface 57b.

  As shown in FIG. 9, the fixed plate 60 is provided with a projecting piece 62 that engages with the mounting seat 40 a of the fixed shaft 40. The protrusion 62 is engaged with the mounting seat 40a, so that the displacement of the fixed side plate 60 with respect to the fixed shaft 40 is suppressed. As shown in FIG. 12, when viewed from the radial direction of the rotation axis X, the inclination angle of the contact surface 61a of the fixed side plate 60 with respect to the rotation axis X is α.

  Further, as shown in FIG. 5, a stopper 70 that is engaged with the upper end portion of the urging member 54 is provided on the upper portion of the fixed shaft 40. The sun gear 49 is urged downward by the urging force of the urging member 54, so that the inner surface of the sun gear 49 is pressed against the teeth 58. The inner surface of the sun gear 49 is provided with a concavo-convex shape that engages with the teeth 58, and the sun gear 49 and the fixed shaft 40 are engaged with each other by the urging force of the urging member 54 to rotate integrally.

 As shown in the figure, when the sun gear 49 is urged downward, the lower surface of the sun gear 49 comes into contact with the inner surface of the bottom wall portion of the drive case 41, whereby the drive case 41 is brought into contact with the upper surface of the mounting seat 40a. It will be energized in the approaching direction.

  As shown in FIG. 8, a pair of movable-side convex portions 71 and 71 that engage with the fixed-side convex portion 57 are integrally formed on the bottom wall portion of the drive case 41 with a space around the fixed shaft 40. . These movable side convex portions 71 and 71 have the same shape, and are formed long in the circumferential direction like the fixed side convex portion 57. As shown also in FIG. 12, both side surfaces 71a, 71a in the longitudinal direction of each movable-side convex portion 71 are configured as flat surfaces inclined with respect to the rotation axis so as to approach each other downward. That is, the dimension in the longitudinal direction of the movable-side convex portion 71 becomes shorter as it goes downward (as it approaches the distal end surface 71b in the protruding direction). Further, the distal end surface 71b is configured to be flat extending in the circumferential direction of the rotation axis X.

  Each movable-side convex portion 71 is movable in the circumferential direction between the pair of fixed-side convex portions 57, 57, and this movable range includes the fixed-side convex portions 57, 57 and the movable-side convex portions 71, It is possible to adjust arbitrarily by the circumferential dimension of 71 and the circumferential position.

As shown in FIG. 4, a movable side plate 80 is provided on the bottom wall portion of the drive case 41 . The movable plate 80 is for covering and protecting the movable convex portions 71 and 71, and is a press-formed product of a steel plate.

  As shown in FIGS. 13 and 14, the movable side plate 80 has a ring shape. Projecting portions 81 and 81 projecting downward corresponding to the shape of the movable-side convex portion 71 are formed at two locations in the circumferential direction of the movable-side plate 80. Each protrusion 81 extends along the side surface 71 a of the movable side convex portion 71, and extends along flat contact surfaces 81 a and 81 a that are inclined in the same manner as the side surface 71 a and the front end surface 71 b of the movable side convex portion 71. And a flat front end surface 81b.

  The movable plate 80 is provided with a projecting piece 82 that engages with the bottom wall portion of the drive case 41. The protrusions 82 are engaged with the bottom wall portion, so that the displacement of the movable plate 80 relative to the bottom wall portion is suppressed.

  As shown in FIG. 12, when viewed from the radial direction of the rotation axis X, the inclination angle of the contact surface 81a of the movable plate 80 with respect to the rotation axis is β. This β is set to an angle different from α. Specifically, α is set to be smaller than β, so that the inclination degree of the contact surface 61a of the fixed-side plate 60 becomes steeper than the inclination degree of the contact surface 81a of the movable-side plate 80. .

  When the mirror housing 4 is in use, as shown in FIG. 12, the contact surface 81a on one side in the circumferential direction of the movable side plate 80 contacts the contact surface 61a of the fixed side plate 60 and further rotates. However, when the mirror housing 4 is in the retracted state, the contact surface 81a on the other side in the circumferential direction of the movable side plate 80 comes into contact with the other contact surface 61a on the fixed side plate 60. Further rotation is restricted.

  When an external force of a certain value or more is applied to the mirror housing 4 in the use state and the retracted state in a direction exceeding the rotation range between the use state and the retracted state, the downward biasing force by the biasing member 54 is applied. Against this, the contact surface 81a of the movable plate 80 moves upward while sliding on the contact surface 61a of the fixed plate 60 (see FIG. 16), and the protruding portion 81 of the movable plate 80 is fixed to the fixed plate. It rides on the flat surface 61b of 60 (refer FIG. 17).

  Further, although the sun gear 49 and the fixed shaft 40 are engaged, when the mirror housing 4 is rotated in a direction exceeding the rotation range of the mirror housing 4 described above, an external force exceeding a certain value is applied. After the movement of the movable plate 80 beyond the rotation range is allowed, the sun gear 49 moves upward against the urging force and the engagement with the teeth 58 of the fixed shaft 40 is released. Thus, the sun gear 49 can rotate with respect to the fixed shaft 40. Thereby, it is possible to prevent an excessive force from being applied to each part.

  In the above configuration, for example, when the mirror housing 4 in the retracted state is switched to the use state, the control device energizes the drive motor 46 so as to rotate forward. As a result, the driving force transmitted from the driving motor 46 to the planetary gear 52 is input to the sun gear 49. As a result, a reaction force that revolves the planetary gear 52 in the positive direction acts along the outer peripheral surface of the sun gear 49, and the reaction case rotates together with the planetary gear 52 until the drive case 41 and the mirror housing 4 are in use.

  When the mirror housing 4 is in use, as shown in FIG. 12, the contact surface 81a on one side in the circumferential direction of the movable plate 80 contacts the contact surface 61a of the fixed plate 60, and further rotation is restricted. The When the control device of the drive motor 46 detects that the rotation is restricted, the energization to the drive motor 46 is stopped. Thereby, the mirror housing 4 is held in use.

  When the mirror housing 4 in use is switched to the retracted state, the control device energizes the drive motor 46 so as to reversely rotate. As a result, the driving force transmitted from the reversed driving motor 46 to the planetary gear 52 is input to the sun gear 49, and a reaction force that revolves the planetary gear 52 in the reverse direction acts along the outer peripheral surface of the sun gear 49. Together with the planetary gear 52, the drive case 41 and the mirror housing 4 rotate until they are retracted.

  When the mirror housing 4 is in the retracted state, the contact surface 81a on the other circumferential side of the movable plate 80 contacts the other contact surface 61a of the fixed plate 60, and further rotation is restricted. When the control device of the drive motor 46 detects that the rotation is restricted, the energization to the drive motor 46 is stopped. Thereby, the mirror housing 4 is held in the retracted state.

  In the use state and the retracted state, the contact surface 81 a of the movable plate 80 is pressed against the contact surface 61 a of the fixed plate 60 by the circumferential driving force of the drive motor 46 and the downward biasing force of the biasing member 54. Become.

  At this time, as shown in FIG. 12, the inclination angle α of the contact surface 61a of the fixed plate 60 is different from the inclination angle β of the contact surface 81a of the movable plate 80, and the contact surface 61a and the contact surface 81a are different. Since they are not parallel, both contact surfaces 61a and 81a are in line contact without surface contact. Thereby, the contact surface 61a and the contact surface 81a become difficult to adhere.

  Therefore, for example, a large external force acts on the mirror housing 4 in a direction exceeding the rotation range, and the contact surface 81a of the movable plate 80 is rotated around the rotation axis X against the urging force of the urging member 54. When it is going to move in the direction, it is easy to move away from the contact surface 61a of the fixed side plate 60, and as shown in FIG. 16, it moves upward while sliding on the contact surface 61a. Therefore, the contact surface 61a of the fixed side plate 60 is not moved by the movement of the movable side plate 80, the floating of the fixed side plate 60 from the fixed side convex portion 57 is suppressed, and the fixed side plate 60 is fixed. Unreasonable deformation of the plate 60 is suppressed.

  Then, as shown in FIG. 17, the protruding portion 81 of the movable plate 80 rides on the flat surface 61b (fixed side convex portion 57) of the fixed plate 60, and the drive case 41 is pushed up to allow the rotation. Thereby, damage of the storage unit 6 is prevented.

  As described above, according to the vehicle side mirror 1 according to this embodiment, the fixed side convex portion 57 of the fixed shaft 40 fixed to the base portion 3 and the movable side of the drive case 41 fixed to the mirror housing 4. While the convex portion 71 is made of resin to reduce the weight of the side mirror 1, both the convex portions 57 and 71 are covered and protected by the fixed side and movable side plates 60 and 80, respectively. Damage can be suppressed. Then, the contact surfaces 61a and 81a of the fixed side plate 60 and the movable side plate 80 are brought into line contact with each other, so that the contact surfaces 61a and 81a are difficult to adhere to each other. Generation | occurrence | production can be suppressed, and the crack of the stationary-side plate 60 can be suppressed.

  Further, since the contact surfaces 61a and 81a of the fixed side plate 60 and the movable side plate 80 are configured as flat surfaces, both the plates 60 and 80 can be easily manufactured. In this case, the contact surfaces 61a and 81a are hardly fixed by a simple configuration in which the inclination angles of the contact surface 61a of the fixed plate 60 and the contact surface 81a of the movable plate 80 with respect to the rotation axis X are different from each other. be able to.

  Further, since the inclination degree of the contact surface 61a of the fixed side plate 60 with respect to the rotation axis X is made steeper than the inclination degree of the contact surface 81a of the movable side plate 80 with respect to the rotation axis X, the position of the mirror housing 4 is unexpectedly changed. While being able to suppress switching, the contact surface 61a and the contact surface 81a become difficult to be caught, and generation | occurrence | production of abnormal noise can be suppressed.

  In addition, the present invention is not limited to the embodiments, and can be implemented in various other forms without departing from the spirit or main features thereof.

  The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

  As described above, the vehicle side mirror according to the present invention is useful for a side mirror including a storage unit, for example.

The surface facing the fixing member in the movable member, the movable-side protrusion protruding to the rotation axis direction is formed, the movable side plate for covering and protecting the movable-side protrusion is attached, the The movable plate is provided with a projecting piece that engages with the movable member and suppresses the displacement of the movable plate with respect to the movable member.
A portion of the movable side plate that covers the side surface of the movable side convex portion engages with a portion of the fixed side plate that covers the side surface of the fixed side convex portion by the biasing force to prevent the mirror housing from rotating. The mirror housing is configured to move so as to ride on the fixed-side convex portion against the biasing force and to allow the mirror housing to rotate.
The contact surface of the fixed plate is a flat surface that covers the side surface of the fixed convex portion,
The contact surface of the movable plate is a flat surface that covers the side surface of the movable convex portion,
As seen from the radial direction of the rotation axis, the inclination of the contact surface of the fixed plate with respect to the rotation axis is set to be steeper than the inclination of the contact surface of the movable plate with respect to the rotation axis,
A vehicle side mirror characterized in that the contact surface of the fixed side plate with the movable side plate and the contact surface of the movable side plate with the fixed side plate are in line contact.
