[Structure] The inside of the door mirror mounting base can be tilted in the vertical direction with respect to the vehicle body direction by a driver's operation or a side wall sensor built in the front end and the lower end of the door mirror main body. As a result, the width of the vehicle body can be reduced and a minimum rear field of view can be secured.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in the structure of a door mirror that secures a driver's rear view in a passenger car or the like.

[0002]

[Prior art]

 Conventionally, a fender mirror installed upright on the fenders of the vehicle has been generally used as a means for ensuring the driver's rear view in passenger cars, etc., but the mirror area is increased to improve rear visibility. Further, in order to improve the appearance of the whole vehicle, more and more door mirrors are installed with a mirror body attached to the base of the A-pillar. Currently, most of the vehicles use door mirrors.

[0003]

[Problems to be solved by the device]

 However, in the case of a door mirror in which the mirror body is attached to the base of the A-pillar in order to increase the mirror area, improve rear visibility, and improve the overall appearance of the vehicle in the above conventional one, Although it is possible to increase the mirror area, rear visibility is improved, but unlike the fender mirror in the door mirror, the mirror body protrudes in the left-right direction larger than the vehicle width. Therefore, it is difficult to grasp the width of the vehicle when passing or passing on a narrow road, and in the case of a door mirror, the viewpoint movement becomes large and the attention when driving tends to be dispersed. It is easy for the door mirrors to come into contact with.

Therefore, in order to prevent breakage of the door mirror body due to contact between vehicles or a passerby on a narrow road, the door mirror body is made foldable so as to be parallel to the vehicle body direction. However, if the door mirror body is tilted once, especially when the vehicle retreats due to a passing vehicle, the rear visibility of the door mirror cannot be expected, and the driver cannot see the rear view of the door mirror. The rear view of the vehicle can be secured only by the rearview mirror and direct visual observation, and there is a drawback that the car body collides with an obstacle or causes traffic congestion due to passing due to a decrease in attention due to a large movement of the viewpoint and an increase in blind spots. is there.

In addition, an ultrasonic sensor detects an obstacle within a predetermined distance in front of the vehicle body, tilts the side mirror so as to be parallel to the vehicle body for a certain time, and then returns to the original position after passing the obstacle. A device that is restored (Japanese Patent Application Laid-Open No. 3-143473) has also been proposed, but since it cannot sense laterally in a narrow passage, it may be gradually changed due to vehicle passing. When approaching the aisle walls, the side mirrors protruding to the side of the vehicle body cannot be sufficiently prevented from being damaged, and the side mirrors themselves are tilted parallel to the vehicle body. Therefore, when the side mirror is tilted, the driver cannot secure a rear view.

Therefore, the present invention is to improve the drawbacks of the above-mentioned conventional ones, and by a simple structure, it is possible to minimize the protrusion of the door mirror to the side of the vehicle body when passing on a narrow road, and It is to ensure that the rear view can be maximized.

[0007]

[Means for Solving the Problems]

 To this end, the mirror tilt switch and the side wall sensors that detect lateral obstacles are attached to the front and bottom ends of the door mirror body, and the door mirror body that mounts the mirror surface on the base of the door mirror is mounted in the vehicle body direction. On the other hand, the door mirror body is connected so that it can be tilted in the vertical direction, and the door mirror body is tilted in conjunction with the signal from the side wall sensor or manually.

[0008]

[Action]

 With the above configuration, when there is an obstacle on the side while driving on a narrow road, the driver determines that there is a possibility of contact between the obstacle and the door mirror body, and operates the door mirror tilt switch, or When the side wall sensor built into the tip of the door mirror body detects an obstacle such as a side wall, it is generated in response to the input by the mirror reversing switch or the detection of the obstacle such as the side wall of the side wall sensor at the tip of the door mirror. According to the signal, the door mirror main body connected to the door mirror mounting base is tilted in the direction perpendicular to the vehicle body direction without changing the direction of the mirror surface. When tilting, the mirror surface of the door mirror body faces rearward without changing its direction, so the driver can secure a minimum rear view. Kill.

[0009] Then, when a narrow road or the like is completed and a space is left in the left-right direction of the vehicle body, it is determined that the driver himself has no possibility of contacting the door mirror body. The door mirror body undulates in the opposite direction again due to a signal generated by operating or the side wall sensor built in at the lower end of the door mirror body to detect it, and the door mirror body returns to its original position again. The driver can secure a normal rear view through the mirror surface of the door mirror body.

[0010]

【Example】

 The invention will be further described with reference to the embodiments shown in the drawings. (1) is a door mirror including an embodiment of the present invention, and this door mirror (1) includes a door mirror body (2) to which a mirror surface (5) for securing a rear view is attached, and this door mirror body. (2) is composed of a door mirror mounting base (3) which is tiltably held by the vehicle body (4).

[0011] Then, the mirror reversing switch disposed inside the vehicle compartment or built in the tip portion (6) and the lower end portion (7) of the door mirror body (2) tiltably held by the door mirror mounting base (3). The bevel gear (11) in the door mirror body (2) that meshes with the bevel gear (10) provided in the door mirror attachment base (3) in synchronization with the input signal from the side wall sensor (8) (9). ), The door mirror body (2) is tilted vertically with respect to the vehicle body direction without changing the direction of the mirror surface (5).

[0012] Since the present invention has the above-mentioned configuration, if there is an obstacle such as a side wall in the passage of a narrow road, the driver may damage the door mirror body (2) by himself. If judged, the side wall sensor (6) that is built in the tip portion (6) of the door mirror body (2) that constitutes the door mirror (1) formed by operating the door mirror tilt switch in the vehicle interior or protruding laterally of the vehicle body (3) ( 8) Detects an obstacle such as a side wall, thereby operating a mirror reversing switch or detecting an obstacle such as a side wall of a side wall sensor (8) built in the tip portion (6) of the door mirror body (2). A motor connected to a bevel gear (11) in the door mirror body (2) that meshes with a bevel gear (10) provided in the door mirror mounting base (3) by an input signal generated in accordance with the motor ( 12) is driven Further, by driving the motor (12), the bevel gear (11) in the door mirror main body (2) rotates along the bevel gear (10) provided in the door mirror mounting base (3). The main body (2) is tilted in a direction perpendicular to the vehicle body direction, that is, the main body (2) is tilted rearward without changing the direction of the mirror surface (5) attached to the door mirror main body (2). Therefore, it is possible to reduce the width of the vehicle body by reducing the amount of protrusion of the door mirror body (2) to the side of the vehicle body (3), and also when the door mirror body (2) is tilted, Since the mirror surface (5) remains in the state of facing rearward without changing its direction, the driver can minimize the rear surface through the mirror surface (5) of the tilted door mirror body (2). Secure the field of view It is what it is.

Then, with the door mirror body (2) protruding laterally of the vehicle body (3) tilted in the vertical direction with respect to the vehicle body direction, the passage of a narrow road or the like is finished, and the vehicle body (3) If there is a room in the left and right directions, the driver judges that there is no possibility of contact between the side obstacle and the door mirror body (2). Or the side wall sensor (9) built in the lower end (7) of the door mirror body (2) detects the spatial margin, the side wall built in the lower end (7) of the door mirror body (2). The inside of the door mirror body (2) that is driven by the driving force of the motor (12) drives the motor (12) built in the door mirror body (2) again by the input signal generated by the sensor (9). Bevel gear (1 0) rotates with respect to the bevel gear (11) provided inside the door mirror mounting base (3) that meshes with the bevel gear (10), so that the door mirror body (2) stands up in the opposite direction. By doing so, the driver returns to the original position, so that the driver can secure a normal rear view through the mirror surface (5) of the door mirror body (2) which has returned to the original position.

When the side wall sensor (9) built in the lower end portion (7) of the door mirror body (2) is judged to be at a dangerous distance in a state where the door mirror body (2) is upside down, driving is performed. A person is warned, and the door mirror body (2) falls down and returns to its original position only when a safe distance is secured between the door mirror body (2) and the side wall. Becomes

[0015]

[Effect of device]

 As described above, the door mirror that projects to the side of the vehicle body is automatically turned upside down or laid down in the vertical direction toward the vehicle body direction by the driver's own operation or the detection of the sidewall sensor, so that it can be used on narrow roads. Even when passing, the amount of protrusion of the door mirror to the side of the vehicle body can be minimized to prevent damage to the door mirror due to contact with side walls etc. It has the excellent effect of ensuring a good visibility and ensuring smooth traffic.
