FIG. 2 is a diagram showing main parts of the vehicle side mirror device of FIG. 1. FIG. FIG. 3 is an exploded perspective view of essential parts of the vehicle side mirror device shown in FIG. 2. FIG. FIG. 3 is a diagram showing the vehicle side mirror device of FIG. 2 viewed from another direction. 3 is a diagram showing a state in which each member is omitted from the vehicle side mirror device of FIG. 2. FIG. FIG. 3 is a diagram showing a main part of the vehicle side mirror device of FIG. 2 along with a cross section. FIG. 3 is a diagram showing a state in which the vehicle side mirror device of FIG. 2 is viewed from above.

A typical configuration of a vehicle side mirror device according to an embodiment of the present invention is that the vehicle side mirror device further includes a mirror housing that supports a mirror that reflects the rear of the vehicle. an electric grating shaft rod extending vertically inside the mirror housing; and an electric grating unit that is arranged within the mirror housing and connected to the mirror housing and that retracts or unfolds the mirror housing by rotating around the electric grating rod as an axis. characterized in that the electric rating unit is coupled to the mirror housing by a first actuator that operates to change the distance between the electric rating unit and the mirror.

According to the above configuration, when the first actuator installed in the mirror housing is operated, the distance between the electric rating unit and the mirror supported by the mirror housing changes. Further, since the electric rating unit is connected to the mirror housing by the first actuator, when the distance between the electric rating unit and the mirror changes, the mirror housing rotates about the electric rating shaft. Therefore, the left and right mirror surface angles of the mirror supported by the mirror housing can be adjusted, and the mirror can be directed toward the outside of the vehicle or toward the inside of the vehicle, for example.

In this manner, the electric axis rod is not only used as an axis when the mirror housing is retracted or expanded by the electric unit, but also used when adjusting the mirror surface angle of the mirror by operating the first actuator. Therefore, according to the above configuration, the number of parts arranged in the mirror housing can be reduced, and the size of the vehicle side mirror device can be further reduced.

The above-mentioned first actuator has a shape extending in the longitudinal direction of the vehicle, and changes the distance between the electric rating unit and the mirror by expanding and contracting, and when the mirror housing is expanded, the electric rating unit of the first actuator changes. The position of one connected end is preferably within a range where the electric grid rod is moved parallel to the mirror surface of the mirror when viewed from above .

In this way, one end of the first actuator installed in the mirror housing, which is connected to the electric rating unit, is positioned within the range where the electric rating axis rod is moved parallel to the mirror surface of the mirror. Because of this layout, the mirror housing can be made smaller.

One end of the first actuator described above is preferably disposed at a position overlapping the electrical grid unit when viewed from above.

In this way, the layout is such that one end of the first actuator installed in the mirror housing is placed at a position overlapping the electric rating unit when viewed from above, so that the mirror housing can be made smaller.

It is preferable that the first actuator described above expands and contracts in a direction substantially perpendicular to a straight line passing through one end and the center of the electric grid rod when viewed from above.

As a result, the first actuator expands and contracts in a direction that efficiently moves the mirror supported by the mirror housing, that is, in a direction that is approximately perpendicular to a straight line passing through one end of the first actuator and the center of the electric grid rod. force can be transmitted to the mirror housing. Therefore, according to the above configuration, by expanding and contracting the first actuator, the mirror housing can be reliably rotated with respect to the electric axis rod, and the left and right mirror surface angles of the mirror supported by the mirror housing can be adjusted.

The vehicle side mirror device described above may further include a fixing portion that fixes the other end of the first actuator to the mirror housing, and the fixing portion may extend in parallel to a straight line when viewed from above.

Thereby, the fixing part fixes the other end of the first actuator to the mirror housing, and also passes in a direction perpendicular to the direction of efficiently moving the mirror, that is, one end of the first actuator and the center of the electric grid rod. It extends in a direction parallel to a straight line. Therefore, according to the above configuration, the force accompanying the expansion and contraction of the first actuator is transmitted from the other end of the first actuator to the mirror housing via the fixed part, and the mirror housing is smoothly and reliably moved relative to the electric shaft rod. It can be rotated.

The above-mentioned vehicle side mirror device further includes a mirror base that is a housing that is located under the mirror housing and is integral with the vehicle body, and the electric shaft rod is connected to the mirror housing and extends into the mirror base. The vehicle side mirror device may further include a second actuator that is installed in the mirror base and swings the lower end of the electric shaft rod to adjust the attitude of the mirror.

According to the above configuration, the lower end of the rod-shaped body swings due to the expansion and contraction of the second actuator installed in the mirror base, that is, located outside the mirror housing. The lower end of the rod-shaped body may be swung in either the vehicle longitudinal direction or the vehicle width direction. As a result, the rod-shaped body is tilted using, for example, the upper wall of the mirror base through which the rod-shaped body penetrates or its vicinity as a fulcrum, and the mirror housing connected to the rod-shaped body is also tilted in the vehicle longitudinal direction or the vehicle width direction. In particular, when the mirror housing is tilted in the longitudinal direction of the vehicle, the angle of the mirror surface of the mirror supported by the mirror housing can be adjusted, and the mirror can be oriented upward or downward, for example.

In this way, the posture of the mirror can be adjusted by tilting the mirror housing itself using the second actuator disposed outside the mirror housing. Therefore, according to the above configuration, since it is not necessary to arrange the second actuator inside the mirror housing, the number of parts arranged inside the mirror housing can be reduced, and the size of the vehicle side mirror device can be reduced.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in these examples are merely illustrative to facilitate understanding of the invention, and do not limit the invention unless otherwise specified. In this specification and the drawings, elements with substantially the same functions and configurations are given the same reference numerals to omit redundant explanation, and elements not directly related to the present invention are omitted from illustration. do.

FIGS. 4A and 4B are diagrams showing the vehicle side mirror device 100 as viewed from the vehicle width direction and obliquely from below, respectively. Note that the mirror base 104 is omitted in FIG. 4(b).

The lower end 128 of the electric shaft rod 112 reaches inside the mirror base 104, as shown in FIG. The external actuator 110 is disposed in front of the lower end 128 of the electric shaft rod 112, and a rod 132 extends and contracts in the longitudinal direction of the vehicle.

The swinging portion 130 connects the lower end 128 of the electric shaft rod 112 and the rod 132 of the external actuator 110, as shown in FIG. 4(b). Further, the external actuator 110 is arranged at a position overlapping the lower end 128 of the electric shaft rod 112 in the vehicle longitudinal direction. The external actuator 110 swings the lower end 128 of the electric shaft rod 112 via the swinging portion 130 by extending and contracting the rod 132 in the longitudinal direction of the vehicle during operation.

The electric rating unit 114 shown in FIG. 2 is disposed within the mirror housing 102 and is further connected to the mirror housing 102, and a part thereof rotates around the electric rating shaft rod 112 to store the mirror housing 102. Or expand. Note that the mirror housing 102 shown in FIG. 1(a) is in an expanded state with the mirror 106 facing toward the rear of the vehicle, and when a part of the electric rating unit 114 rotates around the electric rating shaft rod 112 from the expanded state, , the mirror 106 is in the retracted state facing the side of the vehicle.

The power rating unit 114 includes a power rating motor housing 136 in which a power rating motor 134 is installed, a side base 138, and a base 140, as shown in FIG. The side base 138 is arranged to overlap below the electric motor 134 of the electric motor housing 136. The base 140 is assembled to the electric motor housing 136 and the side base 138 so as to be located below the cylindrical portion 142 of the electric motor housing 136 and on the side of the side base 138.

A spacer 144, an elastic body 146, and a washer 148 shown in FIG. 3 are arranged above the cylindrical portion 142 of the electric motor housing 136, and the electric rod 112 passes through these from above. Further, the electric rating shaft rod 112 passes through the cylindrical portion 142 of the electric rating motor housing 136 and the base 140, and also passes through the electric rating unit case 150.

FIG. 5 is a diagram showing a state in which each member is omitted from the vehicle side mirror device 100 of FIG. 2. As shown in FIG. FIG. 5A shows the vehicle side mirror device 100 with the electric rating unit 114 and the like omitted. FIG. 5(b) shows a state in which an electric rating unit case 150 is added to the vehicle side mirror device 100 of FIG. 5(a).

The electric grid shaft rod 112 passes through a through hole 154 of a convex portion 152 formed in the bottom portion 116 of the mirror housing 102 shown in FIG. 5(a), and its lower end 128 (see FIG. 4(b)) is It is connected to the external actuator 110 via the moving part 130. Therefore, although the electric grid shaft rod 112 swings in accordance with the expansion and contraction of the rod 132 of the external actuator 110 (described later), it does not always rotate.

The electric rating unit case 150 is penetrated by the electric rating shaft 112 as shown in FIG. is combined with Therefore, the electrical unit case 150 does not rotate. Further, the electric rating unit case 150 has a meshing portion 158 that meshes with the base 140 of the electric rating unit 114. Therefore, the base 140 is engaged with the electrical unit case 150 and therefore does not rotate like the electrical unit case 150. In this way, the base 140 of the electric rating unit 114 is connected to the electric rating shaft rod 112 via the electric rating unit case 150.

In the electric rating unit 114, when the electric rating motor 134 is operated, a gear attached to the motor shaft and a threaded gear installed in the side base 138, as an example, mesh and rotate, although not shown. Further, a non-rotating gear disposed in the base 140 around the electric grade shaft rod 112 meshes with a rotating threaded gear disposed along the outer periphery of this gear. The motor housing 136 and the side base 138 rotate together about the electric shaft rod 112.

The vehicle side mirror device 100 further includes an internal actuator 160 disposed within the mirror housing 102, as shown in FIGS. 5(a) and 5(b). Internal actuator 160 has a rod 162. One end 164 of the rod 162 is held in a fixed position by the electric motor housing 136 via a holding part 166 fixed to the electric motor housing 136 shown in FIG. The other end 168 of the rod 162 is fixed to the mirror housing 102 via, for example, a plate-shaped fixing part 170 fixed to the mirror housing 102.

Therefore, the electric rating motor housing 136 and the side base 138 of the electric rating unit 114 rotate together about the electric rating shaft rod 112 as an axis. Then, the mirror housing 102 rotates about the electric shaft rod 112 via the holding part 166, rod 162, and fixing part 170 fixed to the electric motor housing 136. In this way, the mirror housing 102 fixed to the fixed part 170 is retracted or expanded by the driving force of the electric motor 134.

Further, the elastic body 146 held by the upper end 118 of the electric rating shaft rod 112 presses the electric rating unit 114 against the electric rating unit case 150 and presses the electric rating unit case 150 against the bottom part 116 of the mirror housing 102. There is. In this way, the relative positions of the electric rating shaft rod 112 and the electric rating unit 114 are maintained by the elastic body 146.

FIG. 6 is a diagram showing a main part of the vehicle side mirror device 100 of FIG. 2 along with a cross section. The cross section shown in FIG. 6(a) is a cross section obtained by cutting the electric rating shaft rod 112 , the electric rating unit 114 arranged around it, and the like along a cutting line along the longitudinal direction of the vehicle. FIG. 6(b) is an enlarged view of a part of FIG. 6(a).

The electric rating shaft rod 112 passes through the above-mentioned electric rating unit case 150, and further extends through the through hole 154 of the convex portion 152 formed on the bottom portion 116 of the mirror housing 102 shown in FIGS. 6(a) and 6(b). Penetrating. Further, as shown in FIG. 6(b), a retainer 174 made of resin, for example, is arranged between the bottom part 116 of the mirror housing 102 and the upper wall 172 of the mirror base 104.

The upper wall 172 of the mirror base 104 has a convex portion 178 in which an opening 176 is formed, as shown in FIG. Note that in FIG. 3, the mirror housing 102 is omitted. Further, in the mirror base 104, the opening 176 in the top wall 172 is formed larger than the through hole 154 in the bottom 116 of the mirror housing 102, as shown in FIG. 6(b).

The retainer 174 is inserted between the bottom 116 of the mirror housing 102 and the top wall 172 of the mirror base 104, penetrates the electric grid rod 112, and slides between the bottom 116 and the top wall 172. Further, another retainer 180 (see FIG. 3) is arranged within the mirror base 104 and below the convex portion 178 of the upper wall 172.

Another retainer 180 is disposed below the upper wall 172 of the mirror base 104 and penetrates the electric grid shaft rod 112, and slides on the lower surface of the upper wall 172. Note that the other retainer 180 is made of metal or resin, for example, and has higher rigidity than the retainer 174.

Here, in the vehicle side mirror device 100, the behavior of the mirror housing 102 when the external actuator 110 is actuated will be described. First, when the external actuator 110 is actuated, the rod 132 shown in FIG. .

By swinging the lower end 128 of the electric grid shaft rod 112, the electric grid shaft rod 112 moves in the direction of arrow B, with the opening 176 formed in, for example, the upper wall 172 of the mirror base 104 through which the electric grid shaft rod 112 passes, as a fulcrum, or its vicinity. Lean as shown. Here, since the rod 132 expands and contracts to swing the lower end 128 of the electric shaft 112 in the longitudinal direction of the vehicle, the mirror housing 102 connected to the electric shaft 112 is rotated by the arrow shown in FIG. 6(a). As shown in C, the vehicle can be tilted in the longitudinal direction. As a result, in the vehicle side mirror device 100, the angle of the mirror surface of the mirror 106 (see FIG. 1(a)) supported by the mirror housing 102 can be adjusted, and the mirror 106 can be oriented upward or downward.

Although not shown, if the arrangement of the external actuator 110 is changed so that the rod 132 expands and contracts in the vehicle width direction, the lower end 128 of the electric shaft rod 112 is swung in the vehicle width direction, and the mirror The housing 102 can be tilted in the vehicle width direction. Even in such a case, the attitude of the mirror 106 supported by the mirror housing 102 can be adjusted by operating the external actuator 110.

In this manner, in the vehicle side mirror device 100, the attitude of the mirror 106 can be adjusted by arranging the external actuator 110 outside the mirror housing 102 and tilting the mirror housing 102 itself using the external actuator 110. Therefore, according to the vehicle side mirror device 100, there is no need to arrange the external actuator 110 inside the mirror housing 102, so the number of parts arranged inside the mirror housing 102 can be reduced, and the device can be made smaller.

Further, since the opening 176 formed in the upper wall 172 of the mirror base 104 is larger than the through hole 154 in the bottom part 116 of the mirror housing 102 as shown in FIG. It can be tilted over a wider range. Furthermore, when the electric grid shaft rod 112 is tilted using the opening 176 of the upper wall 172 of the mirror base 104 as a fulcrum, the retainers 174 and 180 are arranged above and below the fulcrum, so that the mirror housing 102 is tilted with respect to the mirror base 104. It can be moved smoothly and stably.

Next, in the vehicle side mirror device 100, when the electric rating motor 134 of the electric rating unit 114 is activated, the electric rating motor housing 136 and the side base 138 are integrated with the electric rating shaft rod 112 as an axis as described above. Rotate. The mirror housing 102 connected to the electric motor housing 136 rotates around the electric rod 112 to be retracted or expanded.

Moreover, the upper end 118 of the electric grid shaft rod 112 is rotatably connected by a connecting portion 120, and the diameter of the upper end 118 is larger than that of other parts. Therefore, the mirror housing 102 can stably rotate while being supported via the connecting portion 120 connected to the upper end 118 of the electric shaft rod 112 having a larger diameter.

In this way, the electric axis rod 112 is not only used when swinging by the external actuator 110 to adjust the attitude of the mirror 106, but also used as an axis when the mirror housing 102 is retracted or expanded by the electric unit 114. It is also used as Therefore, according to the vehicle side mirror device 100, the number of parts arranged in the mirror housing 102 can be reduced, and the size can be further reduced.

As shown in FIG. 4A, the electrical rating unit 114 is arranged at a position overlapping the electrical grid shaft rod 112 when viewed from the vehicle width direction with the mirror housing 102 expanded. Therefore, in the vehicle side mirror device 100, when the electric axis rod 112 is swung by the external actuator 110 and the mirror housing 102 is tilted to adjust the attitude of the mirror 106, the oscillating electric axis rod 112 is On the other hand, the amount of offset in the longitudinal direction of the center of gravity of the mirror housing 102 can be reduced. Therefore, according to the vehicle side mirror device 100, when the external actuator 110 tilts the mirror housing 102 in the longitudinal direction of the vehicle to adjust the mirror surface angle of the mirror 106, the rod 132 of the external actuator 110 is required to extend and contract. The force applied can be reduced.

The external actuator 110 is arranged in front of the lower end 128 of the electric shaft rod 112, as shown in FIG. 4(a). Therefore, in the vehicle side mirror device 100, the external actuator 110 does not get in the way when the mirror housing 102 is stored or expanded, and the size of the mirror 106 supported by the mirror housing 102 can be secured.

Further, as shown in FIGS. 4(a) and 4(b), the external actuator 110 is arranged so as to overlap the bottom portion 116 of the mirror housing 102 in the expanded state in the vehicle vertical direction. Therefore, the external actuator 110, which is a heavy object, is placed near the swinging electric grid shaft rod 112. Therefore, in the vehicle side mirror device 100, the moment applied to the mirror base 104 when the external actuator 110 is actuated can be reduced.

Further, the external actuator 110 is arranged so as to overlap the lower end 128 of the electric shaft rod 112 in the longitudinal direction of the vehicle, as shown in FIG. 4(b). Therefore, in the vehicle side mirror device 100, the projected area of the mirror base 104 when viewed from the front can be reduced, and wind resistance during driving can be reduced.

FIG. 7 is a diagram showing a state in which the vehicle side mirror device 100 of FIG. 2 is viewed from above. FIG. 7A shows the entire vehicle side mirror device 100 with the cover 108 (see FIG. 1B) omitted. FIG. 7(b) shows a part of the vehicle side mirror device 100 in an enlarged manner, with the mirror housing 102 of FIG. 7(a) omitted.

As described above, one end 164 of the rod 162 of the internal actuator 160 is held by a holding portion 166 fixed to the electric motor housing 136 of the electric power unit 114. The other end 168 of the rod 162 is fixed to the mirror housing 102 via a fixing part 170 fixed to the mirror housing 102. In other words, electric motor housing 136 is coupled to mirror housing 102 by internal actuator 160 .

As shown, the rod 162 of the internal actuator 160 expands and contracts in the direction indicated by the arrow E, which is approximately perpendicular to the straight line D passing through the one end 164 of the rod 164 and the center 182 of the electric shaft rod 112, thereby causing the fixed portion to Force can be transmitted to mirror housing 102 via 170.

When the internal actuator 160 operates so that the rod 162 expands and contracts in the direction shown by arrow E, the distance between the mirror housing 102 that supports the mirror 106 shown in FIG. change. That is, when the mirror housing 102 rotates about the electric shaft rod 112 as shown by arrow F in FIG. 7(a), the distance between the mirror 106 and the electric motor housing 136 changes. Therefore, according to the vehicle side mirror device 100, the left and right mirror surface angles of the mirror 106 supported by the mirror housing 102 can be adjusted, and the mirror 106 can be directed toward the outside of the vehicle or toward the inside of the vehicle, for example.

In this way, the electric axis rod 112 is not only used as an axis when the mirror housing 102 is retracted or expanded by the electric unit 114, but also when the internal actuator 160 is actuated to adjust the mirror angle of the mirror 106. is also used. Therefore, according to the vehicle side mirror device 100, the number of parts arranged in the mirror housing 102 can be reduced, and the size can be further reduced.

In the mirror housing 102, the position of one end 164 of the rod 162 of the internal actuator 160 is within a range R that is parallel to the mirror surface of the mirror 106 when the electric shaft rod 112 is viewed from above, as shown in FIG. 7(a). It's laid out like it's inside. Furthermore, the mirror housing 102 is laid out so that one end 164 of the rod 162 is placed at a position overlapping the electric rating unit 114 when viewed from above. In the vehicle side mirror device 100, such a layout allows the mirror housing 102 to be downsized.

The rod 162 of the internal actuator 160 can expand and contract in a direction shown by an arrow E that is substantially orthogonal to the straight line D when viewed from above, that is, in a direction that efficiently moves the mirror 106 supported by the mirror housing 102. Therefore, according to the vehicle side mirror device 100, by operating the internal actuator 160, the mirror housing 102 can be reliably rotated with respect to the electric axis rod 112, and the left and right mirror angles of the mirror 106 can be adjusted.

The fixing part 170 shown in FIG. 7A fixes the other end 168 of the rod 162 of the internal actuator 160 to the mirror housing 102, and extends parallel to the straight line D when viewed from above. Note that the direction of the straight line D is perpendicular to the direction in which the rod 162 expands and contracts (see arrow E), that is, the direction in which the mirror 106 is efficiently moved. Therefore, according to the vehicle side mirror device 100, the force accompanying the expansion and contraction of the rod 162 is transmitted from the other end 168 of the rod 162 to the mirror housing 102 via the fixing part 170, and 102 can be rotated smoothly and reliably.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to such examples. It is clear that those skilled in the art can come up with various changes and modifications within the scope of the claims, and these naturally fall within the technical scope of the present invention. Understood.
