Description

  The present invention relates to a side mirror.

2. Description of the Related Art Conventionally, the vehicle includes a direction changing unit that drives a side mirror in a side mirror of a vehicle to change the direction of a reflecting surface of the side mirror, and a control unit that controls the direction changing unit. It is configured to detect an operation for changing the lane of the vehicle or turning left or right by hand, and when the operation is detected, the direction of the reflecting surface is a predetermined outward state that faces the outside of the vehicle from the basic state. A side mirror is known that controls the direction changing means in this way (see, for example, Patent Document 1).
JP-A-2005-35468

  However, in the conventional side mirror, the entire reflecting surface of the side mirror is moved so as to be in a predetermined outward state facing the outside of the vehicle. For this reason, there has been a demand for simultaneously confirming a necessary direction depending on driving conditions while maintaining a state in which the vehicle can be visually recognized obliquely backward.

  The problem to be solved by the present invention is to provide a side mirror capable of simultaneously confirming a necessary direction according to a driving situation while maintaining a state in which the vehicle can be visually recognized obliquely backward.

  In order to solve the above-mentioned problem, the side mirror according to claim 1 is a side mirror for visually recognizing an oblique rear side of a vehicle, wherein the reflecting surface is divided in the vehicle width direction of the side mirror, and at least a part of the divided reflecting surfaces is divided. The reflection direction is made variable by driving.

  In the side mirror of the present invention, as described above, the reflection surface is divided in the vehicle width direction of the side mirror, and the reflection direction of at least some of the divided reflection surfaces can be changed by driving, so that the remaining divided portions It is possible to simultaneously check the necessary direction according to the driving situation by changing the reflection direction of at least some of the divided reflection surfaces by driving while maintaining the state in which the vehicle can be visually recognized obliquely behind the vehicle. The effect of becoming like this is acquired.

  Embodiments of the present invention will be described below with reference to the drawings.

The side mirror of this embodiment corresponds to the invention described in claims 1-7.
First, the configuration will be described. FIG. 1 is a front view showing a side mirror of an embodiment. FIG. 2 is a plan view showing the internal structure of the side mirror of the embodiment. FIG. 3 is a front view of the main part showing the internal structure of the side mirror of the embodiment.
As shown in FIGS. 1 and 2, the side mirror 1 of this embodiment includes a mirror case 2, a fixed mirror portion 3, a mirror drive electric motor 4, a movable mirror portion 5, a connecting shaft 6, and a movable mirror. A part driving electromagnetic solenoid 7 and a link mechanism 8 are provided.

The side mirror 1 of this embodiment is a door mirror, and is provided in a state where the mounting portion 21 of the mirror case 2 is fixed to the front door 9.
The fixed mirror portion 3 is a portion having an outer reflecting surface 30a obtained by dividing the reflecting surface 30 into two in the vehicle width direction, and has a width of about 2/3 of the reflecting surface 30 in the width direction.
The fixed mirror unit 3 is configured to freely adjust the reflection direction of the outer reflection surface 30a in the vertical and horizontal directions by driving the mirror-surface driving electric motor 4.

The movable mirror portion 5 is a portion having an inner reflecting surface 30b obtained by dividing the reflecting surface 30 in the vehicle width direction, and has a width of about 1/3 of the reflecting surface 30 in the width direction.
The movable mirror unit 5 is configured to be able to change the reflection direction of the inner reflection surface 30b so as to reflect the side side in front of the visible range of the outer reflection surface 30a.

The connecting shaft 6 constitutes a connecting means in which the movable mirror portion 5 having the divided inner reflection surface 30b is connected to be rotatable in a horizontal plane.
The movable mirror portion driving electromagnetic solenoid 7 constitutes drive means capable of driving the connecting shaft 6 forward and backward in the vehicle width direction of the inner reflecting surface 30b.
The link mechanism 8 is a mechanism that changes the advancing / retracting operation of the connecting shaft 6 in the vehicle width direction by the electromagnetic mirror 7 for driving the movable mirror unit to a rotating operation in the horizontal plane of the inner reflecting surface 30b.

  As shown in FIGS. 2 and 3, the link mechanism 8 includes slide pins 81 and 82 provided on both the upper and lower end surfaces of the movable mirror portion 5 in the vicinity of both ends in the vehicle width direction, and each slide pin on the fixed mirror portion 3. It comprises slide grooves 83 and 84 for guiding 81 and 82 in a slidable manner.

Both the slide grooves 83 and 84 are formed in an inclined shape so that the distance between the slide grooves 83 and 84 increases toward the inside of the mirror case 2.
The movable mirror unit driving electromagnetic solenoid 7 is fixed to the back side of the fixed mirror unit 3. The slide grooves 83 and 84 are respectively formed on the upper and lower walls 10 a and 10 b of the U-shaped frame 10 that is connected and fixed to the fixed mirror portion 3.

  Further, the fixed mirror unit 3 and the movable mirror unit 5 are arranged so that no gap is formed in the divided unit E, and the movable mirror unit 5 rotates along the slide groove 83 on the divided end surface of the fixed mirror unit 3. In order to make this possible, a relief portion 31 cut obliquely along the inclination of the slide groove 83 is formed (see FIG. 4).

Next, the operation of this embodiment will be described.
FIG. 4 is an explanatory view of the reflection direction changing operation of the movable mirror unit 5, FIG. 5 (a) is a diagram showing the state of the side mirror during normal driving, and FIG. 6 (a) is a diagram showing the field of view of the side mirror during normal travel, and FIG. 6 (b) is a diagram showing the field of view of the side mirror when changing lanes.

[During normal driving]
During normal traveling of the vehicle, as shown in FIGS. 4 (a), 5 (a), and 6 (a), a drive signal to the movable solenoid drive electromagnetic solenoid 7 is not output. The connecting shaft is pushed out. As a result, the reflecting surface 30b on the inner side of the movable mirror unit 5 is arranged in a substantially straight line along the reflecting surface 30a on the outer side of the fixed mirror unit 3.
In this state, an oblique rear visual field F of the vehicle including the side surface of the vehicle body is secured over the entire reflecting surface 30 of the side mirror 1.

[When changing lane]
At the time of changing the lane of the vehicle, if a direction instruction operation is detected, as shown in FIGS. 4 (B) to (D), FIG. 5 (B) and FIG. The drive signal is output, and thereby the connecting shaft is pulled. As a result, the slide pins 81 and 82 slide along the slide grooves 83 and 84, and the reflection direction of the inner reflection surface 30b, which was responsible for the field of view of the side surface of the vehicle body during normal driving, is the outer reflection surface. It changes so that it may face to the front side from the diagonal rear view of the vehicle which is the visible range of 30a.
In this state, the oblique rear visual field F1 of the vehicle is secured by the outer reflecting surface 30a of the fixed mirror unit 3, and the oblique rearward of the vehicle that is in the visible range of the outer reflecting surface 30a by the inner reflecting surface 30b of the movable mirror unit 5. A field of view F2 on the side and in front of the field of view is secured.
The oblique rear visual field F1 formed by only the outer reflective surface 30a has a smaller viewing angle than the visual field F including the inner reflective surface 30b, but the smaller part includes a vehicle side surface during normal driving. Since it is a rear view, the vehicle diagonally backward confirmation is sufficient.

Next, the effect of this embodiment will be described.
In the side mirror of this embodiment, as described above, the reflection surface 30 is divided in the vehicle width direction of the side mirror 1 so that the reflection direction of the divided inner reflection surface 30b can be freely changed by driving. By reflecting the side side in front of the visible range of 30a, the remaining reflective surface 30a of the divided portion maintains the state in which the vehicle can be seen obliquely rearward of the vehicle, while maintaining the state of the outer reflective surface 30a. An effect is obtained that the side side can be simultaneously confirmed in front of the visible range.

  Note that the side of the vehicle body is usually reflected in the main reason that the clearance between the vehicle body and the object outside the vehicle is confirmed, which is not very meaningful when changing lanes. Therefore, it is possible to confirm obstacles such as other vehicles in the blind spot by moving only this portion (inner reflection surface 30b) so that the outer side (front side from the oblique rear view of the vehicle and the side) can be seen. it can.

  Further, the side mirror 1 of this embodiment is applied to a door mirror that is more difficult to check on the side side in front of the visible range of the outer reflecting surface 30a than the side mirror provided on the front fender. Lateral confirmation can be improved.

In the conventional side mirror, the entire reflecting surface of the side mirror is moved and converted into a pulse signal from the current change caused by the rotation of the motor to return to the original position. When the movement amount is returned to the original position by counting, control is performed using the number of pulses.
However, with this method, an error occurs in the return position due to the inertia of the motor, etc., and the error is accumulated further by repeatedly performing the operation, and the entire reflecting surface of the side mirror is displaced from the original position assumed. There is.

  On the other hand, in the side mirror of the embodiment, only the portion (inner reflection surface 30b) that was normally in charge of the field of view of the side surface of the vehicle body is directed outward (frontward and sideward from the oblique rear view of the vehicle). By moving, the portion (outside reflecting surface 30a) that has been in charge of the oblique rear view of the vehicle is fixed, so that a deviation due to accumulation of errors due to the reflecting surface operation does not occur.

  Further, since the connecting shaft 6 connected to the movable mirror portion 5 so as to be rotatable in a horizontal plane is driven to move back and forth in the vehicle width direction by the movable mirror portion driving electromagnetic solenoid 7, the movement of the movable mirror portion 5 is increased. Is a constant action from end to end of the initial position and the final position due to the forward / backward drive of the connecting shaft 6, so that the inner reflecting surface 30 b does not shift when returning to the initial position after the operation.

  Further, the upper and lower end surfaces of the movable mirror unit 5 are used as a link mechanism for changing the moving operation of the connecting shaft 6 in the vehicle width direction by the electromagnetic mirror 7 for driving the movable mirror unit to the rotating operation in the horizontal plane of the inner reflecting surface 30b. The slide pins 81, 82 provided near both ends in the vehicle width direction, and slide grooves 83, 84 for slidably guiding the slide pins 81, 82 to the fixed mirror portion 3, both slide grooves 83 and 84 are formed so as to be inclined so that the distance between them increases toward the inside of the mirror case 2, so that the angle of the movable mirror unit 5 can be smoothly adjusted only by driving the connecting shaft 6 forward and backward. You can change it.

  Further, a clearance 31 cut obliquely along the inclination of the slide groove 83 is formed on the split end surface of the fixed mirror 3, so that a gap is formed in the split E between the fixed mirror 3 and the movable mirror 5. The movable mirror portion 5 can be rotated along the inclination of the slide groove 83 without forming the.

  In addition, since the steering angle is detected by the steering angle sensor when the lane is changed and the reflection direction of the reflection surface 30b inside the movable mirror unit 5 is automatically changed, no special operation is required. When you change lanes, you can check other vehicles in the blind spot.

  Although the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included in the present invention.

  For example, in the embodiment, the divided inner reflection surface can be changed by the driving operation, but the outer reflection surface may be changed by the driving operation.

  Moreover, although applied to the door mirror in the embodiment, it can also be applied to a side mirror provided in the front fender.

In the embodiment, the reflection direction of the inner reflection surface 30b is changed according to the steering angle. However, the reflection direction of the inner reflection surface 30b may be changed by detecting a direction instruction operation. . In this case, in addition to the time when the lane is changed, it is possible to check other vehicles in the blind spot when turning left or right.
Further, the reflection direction of the inner reflection surface 30b may be changed based on guidance by navigation.

  If one of the divided reflecting surfaces is rotated in the vertical plane, the white line position can be confirmed when the vehicle is parked in the back.
