[Industrial applications]

 The present invention relates to a retractable rear under mirror device arranged at a rear portion of a vehicle body.

[Prior art]

 As a conventional rear under mirror, the one shown in FIG. 6 has been put into practical use (see page D-22 of "NISSAN Vanette Serena" new model car explanation published by Nissan Motor Co., Ltd. June 1991). That is, the rear under mirror 52 is arranged at the rear end of the roof 51 of the vehicle body 50 of the one-box type vehicle. The rear under mirror 52 has an arm 53 whose upper end is fixed to the roof 51 and is bent downward, and a mirror housing 54 located behind a rear window 56 is provided at the lower end of the arm 53. Has been. A mirror body 55 is mounted on the lower surface side of the mirror housing 54, and the mirror body 55 is a convex mirror.

In such a configuration, in the one-box type vehicle, it is difficult to sufficiently confirm the state of the lower rear portion of the vehicle body 50 by visually observing the door mirror when the vehicle moves backward. Therefore, when the vehicle retreats, the driver can use the rear under mirror 52 to check the state of the lower rear part of the vehicle body 50 reflected in the mirror body 55 of the rear under mirror 52.

[0003]

[Problems to be solved by the device]

 As described above, the rear under mirror 52 is used to confirm the state of the lower rear portion of the vehicle body 50, which is difficult to confirm with the door mirrors. Therefore, the mirror main body 55 covers at least the entire vehicle width range. Therefore, it is necessary to have the function of showing the state of the lower rear part. Moreover, since the driver needs to be able to visually recognize the state of the rear lower part of the mirror main body 55 through the rear window 56, the position is behind the rear window 56. Therefore, if the area of the mirror main body 55 is increased, the rear view from the rear window 56, which is necessary for the rearview mirror when traveling forward, is reduced.

For this reason, a convex mirror having a large curvature is used for the mirror body 55 so that the entire body width can be projected while being small in size, and the visibility at the lower rear portion and the rear view from the rear window 56 are both secured. I am letting you. As a result, by using the mirror body 55 having a large curvature, the image reflected on the mirror body 55 is inevitably small.

The present invention has been made in view of the above-described conventional problems, and provides a retractable rear undermirror device that can ensure a sufficient rear view while using a larger mirror body. That is the purpose.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, according to the present invention, a rear spoiler provided at a rear end of an upper portion of a vehicle body is provided with a storage portion for a rear under mirror, and the storage position for storing the rear under mirror in the storage portion is provided. And a driving means for driving the rear under mirror to both the positions, while supporting the rear under mirror so as to be displaceable in a predetermined use position.

[Action]

 In the above configuration, when the vehicle is moved backward, the drive means is operated to drive the rear under mirror to the use position, and the rear under mirror driven to this use position visually recognizes the lower rear part of the vehicle body. Further, when the vehicle starts, the drive means is actuated again to drive the rear under mirror in the use position to the storage position. As a result, the rear under mirror is housed in the storage section provided on the rear spoiler.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a rear spoiler 3 is attached to a rear end portion of a roof 2 of a vehicle body 1 of a one-box vehicle. The rear spoiler 3 has an upper surface portion 4 extending obliquely upward from the roof 2 and a lower surface portion 6 extending obliquely downward from the tip portion 5, and the lower surface portion 6 is provided with a rectangular opening-shaped storage portion 7. Has been.

Inside the rear spoiler 3, as clearly shown in FIG. 3, a first motor 8 and a second motor 9 are arranged as driving means, and the rotation shaft of the first motor 8 includes a worm gear 10. Is stuck. A pinion gear 11 is meshed with the worm gear 10, and a first rotating shaft 12 extending in the vehicle width direction is fixedly inserted in the center of the pinion gear 11. One ends of arms 13 1 and 13 3 are fixed to both ends of the first rotary shaft 12, and the other ends of the arms 13 and 13 are bosses provided on both sides of the upper end of the rear under mirror 14. It is pivotally supported by 15.

On the other hand, the second motor 9 is provided with a second rotating shaft 16 protruding from both side surfaces. The second rotary shaft 16 extends parallel to the first rotary shaft 12, and drums 17, 17 are fixed to both ends thereof. One end of a wire 18 is fixed and wound around the drums 17, 17, and the other end of the wire 18 is fixed to both sides of the lower end of the rear under mirror 14.

The rear under mirror 14 is composed of a cover member 19 provided with the boss portion 15 and a mirror body 20 attached to the back side of the cover member 19, and the mirror body 20 is It has a mirror surface 21 formed of a convex surface. The rear under mirror 14 has a size that can be stored in the storage portion 7 when the rear under mirror 14 reaches the storage position A shown by the chain line in FIG. Further, in the state of the use position B shown by the implementation line in the figure, the length and the rotation angle of the arm 13 are set so as to reach behind the rear window 24 (see FIG. 2).

A spring (not shown) is inserted in the pivotal support between the other end of the arm 13 and the upper end of the under mirror 14, whereby the arm 13 and the rear under mirror 14 are shown in FIG. It is urged in the expansion direction C. Further, in the state of the use position B, the stopper 25 provided at the tip of the arm 13 contacts the surface of the cover member 19 so that the rear under mirror 14 resists the urging in the expanding direction C. , Is configured to be set at a predetermined angle. Here, the predetermined angle is an angle at which the rear lower part of the vehicle body 1 is reflected on the mirror surface 21 and the driver can visually recognize the image reflected on the mirror 21 through the rear window 24.

FIG. 4 is a block diagram showing the control system of the present embodiment, in which the gear position sensor 22 detects the shift position of the running gear set by the shift lever provided in the vehicle, and the controller 23 The controller 23 is configured to control the first and second motors 8 and 9 in accordance with the input shift position.

In the present embodiment having the above-described configuration, the rear under mirror 14 is held at the storage position A in the initial state and is housed in the storage section 7 with the mirror surface 21 inside. In the state of the storage position A, the surface of the cover member 19 of the rear under mirror 14 is flush with the surface of the lower surface portion 6 of the rear spoiler 3, and the arm 13 is in the state of the use position B. Standing up, most of the wire 18 is wound around the drum 17.

In this initial state, when the driver turns on the ignition key switch, in response to this, the controller 23 starts the operation according to the flowchart shown in FIG. That is, first, based on the output signal from the gear position sensor 22, it is determined whether or not the shift position is "R" (reverse) (S1). If the result of this determination is that the shift position is a traveling position other than R, etc., the standby state is maintained without executing the following processing. Then, when the driver shifts the shift lever to "R" in order to move the vehicle backward, the process proceeds from S1 to step S2, in which an operation signal is output to the first and second motors 8 and 9, and the motor is normally rotated for a predetermined time.

Then, along with the normal rotation of the first motor 8, the worm gear 10, the pinion gear 11, and the first rotary shaft 12 rotate, the arm 13 gradually tilts, and the normal rotation of the second motor 9 occurs. Accordingly, the wire 18 is sent out from the drum 17. As a result, the rear under mirror 14 biased in the expanding direction C rotates so that the mirror surface 21 faces downward while increasing the angle formed with the arm 13.

Then, when the first and second motors 8 and 9 have completed normal rotation for a predetermined time and then stopped, the rear under mirror 14 reaches the use position B. In the state of the use position B, as described above, the rear under mirror 14 is located behind the rear window 24, and the stopper 25 abuts on the surface of the cover member 19 so that the rear under mirror 14 is set at a predetermined angle. As a result, the rear lower part of the vehicle body 1 is reflected on the mirror surface 21, and the driver can retreat the vehicle while visually recognizing the image reflected on the mirror 21 through the rear window 24.

After the backward movement is completed, the driver operates the shift lever to start forward traveling and shifts to a traveling position other than “R”, the determination in S3 is YES, and the process proceeds from S3 to S4. The first and second motors 8 and 9 are reversely rotated for a predetermined time. Then, with the reverse rotation of the first motor 8, the worm gear 10, the pinion gear 11, and the first rotary shaft 12 rotate in the opposite direction to the above, and the arm 13 gradually stands up, and with the reverse rotation of the second motor. Then, the wire 18 is wound around the drum 17. As a result, the rear under mirror 14 biased in the expansion direction C rotates so that the mirror surface 21 faces upward while reducing the angle formed with the arm 13 against the bias. .

Then, when the first and second motors 8 and 9 stop rotating after the normal rotation for a predetermined time, the rear under mirror 14 reaches the storage position A described above. At the storage position A, as described above, the rear under mirror 14 is housed in the storage portion 7 with the surface of the cover member 19 being flush with the surface of the lower surface portion 6 of the rear spoiler 3. It is located above the rear window 24. Therefore, the rear under mirror 14 has no influence on the rear view from the rear window 24 during forward traveling. That is, even if the area of the mirror surface 21 is increased and the curvature thereof is decreased so that a larger image is displayed, the rear view from the rear window 24 does not decrease. Therefore, by using the rear under mirror 14 which is larger and has the mirror surface 21 having a small curvature, it is possible to secure sufficient visibility in the rear while securing visibility of the lower rear portion of the vehicle body 1.

Moreover, since the rear under mirror 14 fits flush with the storage portion 7 of the rear spoiler 3, it does not affect the air resistance or appearance quality of the rear spoiler 3, and the mirror surface 21 is placed inside. It is also possible to prevent the inconvenience that the mirror surface 21 is contaminated by the mud that is splashed up when the vehicle is traveling forward.

In the embodiment, the drums 17, 17 are rotationally driven by the second motor 9, but a structure in which both drums 17, 17 are biased in the winding direction by springs It is possible to operate in the same manner as described above. Further, in the embodiment, the motors 8 and 9 are controlled according to the shift position of the shift lever, but the motors 8 and 9 may be operated by a simple switch operation.

[0021]

[Effect of device]

 As described above, according to the present invention, the rear spoiler is provided with the storage part for the rear under mirror, and the rear under mirror is driven to the storage position housed in the storage part and the predetermined use position. In the position state, the rear under mirror can be positioned outside the rear view from the rear window. Therefore, even if the rear under mirror is enlarged to increase the area of the mirror body and reduce its curvature so that a larger image can be displayed, the rear view from the rear window is not reduced. . As a result, by using the rear under mirror having a mirror body that is larger and has a smaller curvature, it is possible to secure sufficient visibility in the rear while ensuring the visibility of the lower rear part of the vehicle body.
