Description

  The present invention relates to an imaging device for confirming the state of the front wheel side and the rear wheel side on the driver's seat side and the passenger seat side of a vehicle with images, a monitor device, and a vehicle periphery visual recognition device provided with an illumination lamp.

  Conventionally, there was only a door mirror (or side mirror) to know the left and right surroundings while driving a car, and the feet (front and rear wheels) of the car were inconvenient and inconvenient. In addition, it was inconvenient when changing the course because both sides of the car were dark at night.

  Therefore, it was very difficult to get the position of the wheel from the driver's seat, especially in the case of beginners, when the vehicle was backed and widened, and even the experienced person did not know the position of the wheel. It only relied on intuition.

  The object of the present invention is to solve such drawbacks and to make the automobile safer and easier to move.

  Near the lower right side of the door mirror (or side mirror), two front and rear CCDs or CMOS (imaging devices that convert images into electrical signals) are provided approximately back-to-back. After that, it will be reproduced on a monitor provided in a place that is easy to see in the driver's seat. Hereinafter, only the CCD is used.

  And, in order to make it easy to see the front, rear, left and right wheel sides even in a dark place such as at night, illumination lamps are provided on the vehicle body that hits the upper side of the wheels.

Further, it is desirable to provide a CCD near the illumination lamp, and to integrate it if possible.
However, in this case, the CCD provided on the door mirror is not necessary.

The effect is that the two CCDs configured substantially back to back image the front wheel side and the road surface for the front, and the rear wheel side and the road surface for the rear, and monitor the electrical signals through the processing unit. Reproduce the image with.
In other words, when the door mirrors of the present invention are provided on both the left and right sides of the automobile, it is like providing four sets of digital cameras excluding the shutter and the recording mechanism.
Therefore, the front, rear, left and right wheels and the road surface condition can be checked on the monitor while the driver is seated, and the illumination lamps provided on the vehicle body are also lit in conjunction.
The same applies to the integration of the illumination lamp and the CCD. Turn off the power when not in use.

  If it is desired to view only the front and rear wheel sides on the passenger seat side, the door mirror of the present invention only needs to be provided on the passenger seat side, and therefore only two processing units and monitors are required. become. However, it is desirable that four lighting lamps provided on the upper side of the wheel be permanently installed on both sides of a normal vehicle.

  As described above, the vehicle is provided with the door mirror and the illumination lamp of the present invention, so that the state of the front and rear wheels and the road surface in the driver's seat, that is, the state of the foot of the vehicle is well reproduced on the monitor, so the back and the width are reduced. Even beginners can drive safely without difficulty.

  In addition, since two CCDs are provided on one door mirror, and the front wheel side and the rear wheel side are independent of each other, the direction of the CCD can be adjusted individually, which is easy.

  Since it illuminates very close to the wheel and the road surface, the brightness is sufficient and the image pickup state with the CCD is very good, and it is also very effective for work such as when it is necessary to change tires at night.

  When backing a car or bringing it closer together, especially for beginners, the position of the wheel was very difficult from the driver's seat, and even the experienced person did not know the position of the wheel. It only relied on.

  An object of the present invention is to solve such drawbacks and make it easy to visually recognize the outside of a wheel and the state of a road surface, a side groove, a partition line, and the like at a driver's seat.

Underneath the door mirror or side mirror, on the opposite side of the mounting part, two CCD cameras for front and rear, or two CMOS cameras (imaging devices that convert images into electrical signals) are provided approximately back to back. The signal is output through a processing unit so that the image is reproduced on a monitor provided in a place that is easy to see in the driver's seat. Hereinafter, only the CCD camera is used.
In this case, the CCD camera means a simplified CCD camera module, or a CCD board camera or a CMOS camera.

  And in order to make it easy to see the front, rear, left and right wheel sides even in a dark place such as at night, illumination lamps are provided on the vehicle body that hits the upper side of the wheel.

  In addition, it is desirable to provide a CCD camera near the illumination lamp, and if possible, an integrated camera. However, in this case, a CCD camera provided in the door mirror portion is unnecessary.

The effect is that the front mirror has a front wheel outer surface and a road surface, both in the case of two CCD cameras provided substantially back-to-back on the door mirror, and in the case where a CCD camera is provided in the vehicle body that hits the upper side of each wheel. For the rear, the rear wheel outer side and the road upper surface are imaged, and the electric signals are reproduced on the monitor through the processing units.
Therefore, it is possible to check the front, rear, left and right wheels and the state of the road surface while staying in the driver's seat. At this time, the illumination lamp provided on the vehicle body is also lit in conjunction.
The same applies to the case where the illumination lamp and the CCD camera are integrated. When not in use, the power is turned off.
