Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a visual field visualizing device for a vehicle.

[Conventional technology]

For example, in the case of a truck, the size of the vehicle body is large. Therefore, in order to prevent the occurrence of contact accidents by visually checking the sides and rear of the cabin during driving, as shown in the perspective view of FIG. Three rear view mirrors 01, underview mirrors 02, and side underview mirrors 03 are provided in a projecting manner, and the rear view mirror 01 is particularly large.

Although these mirrors are crucial to the safety movement,
Wind noise is generated, running resistance is increased, and the mirror itself may cause contact accidents, which is not good.

[Problems to be solved by the device]

The present invention has been proposed in view of such circumstances, and it is easy to reduce the size of the protruding portion, has a good external appearance, and visually recognizes the rear field of view along the left and right side surfaces of the vehicle body and the area immediately behind the vehicle body to prevent an accident from occurring. It is an object of the present invention to provide a visual field visibility device for a vehicle that is useful for

[Means for Solving the Problems] For this purpose, the present invention is directed to a pair of left and right TV cameras for taking a rear view along the left and right side surfaces of a vehicle body, and a rear TV camera for taking a rear view of the vehicle provided on the rear surface of the vehicle body. The left and right TVs are installed near the upper end of the center of the windshield inside the vehicle.
It is characterized in that it has a video display screen that always displays the video of the camera to the left and right and displays the video of the rear TV camera in the central part in conjunction with the reverse shift of the transmission.

[Action]

With this configuration, the rear view along the left and right sides of the vehicle body is always displayed on the left and right sides of the image display screen by the pair of left and right TV cameras, and when the vehicle is moving backward, the rear TV camera is linked with the reverse shift of the transmission. Displays the rear view of the vehicle in the center of the video display screen.

〔Example〕

An embodiment in which the present invention is applied to a truck will be described with reference to the drawings. FIG. 1 is a perspective view showing a cabin thereof, FIG. 2 is a partially enlarged view showing a front pillar thereof, FIG. 3 is an overall plan view, and FIG. The figure is a perspective view of the inside of the cabin as seen from the front, and FIG. 5 is a front view showing an image displayed on the image display screen of FIG. 4. FIG. B) shows a view on both sides of the vehicle body and a view immediately after the vehicle body, and FIG. 7C shows a view directly below the cabin.

First, in FIGS. 1 to 4, reference numeral 1 denotes a pair of left and right small TV cameras projecting from the front pillars 3 on both sides of the cabin 2 via flexible stays 4, and the TV cameras 1 and 1 are always the cabin and the vehicle body, respectively. The camera is oriented so that it can be photographed at the bottom rear of the camera (Fig. 3), but it is supported by changing the camera angle so that each camera is directed just below the front of the camera by one-touch remote control operation inside the camera.

5 is a loading platform, 6 is a mirror-size image display screen of a CRT or the like which is attached near the upper part of the windshield of the cabin and shows the images of the TV cameras 1 and 1, and 7 is a rear view of the loading platform attached to the upper rear end of the loading platform 5. It is a rear TV camera.

In such a structure, three TV cameras are provided, including a pair of left and right provided on both sides of the cabin and one provided at the upper end of the rear end of the luggage carrier.

The field of view behind and behind the vehicle body by the pair of left and right TV cameras 1, 1 is
It is the range shown by hatching in FIG. 3, and its image is
As shown in the figure, the image is displayed on the left half and right half of the video display screen 6, respectively.

The rear TV camera 7 is turned on in conjunction with the reverse gear shift when the vehicle moves backwards, and the rear view of the loading platform is shown in FIG. 5 (B).
As shown in, the image is displayed in the central portion of the video display screen 6.

When you want to look right under the front of the cabin, press the one-touch switch button, and the desired TV camera points downwards with the remote controller, and if the child 8 is there, it will be displayed, as shown in FIG. 5 (C). .

Here, since the pair of left and right TV cameras 1 are respectively supported by the flexible stays 4, the TV can be used on a narrow road.
When the camera touches another object, the flexible stay 4
By bending, it prevents the TV camera from being damaged.

The left and right TV cameras use a wide-angle lens to direct sideways or directly below, and incorporate a part of the direct view and part of the side view over a fairly wide range, and display this on the video display screen. Can be projected.

With such a structure, the following effects can be obtained.

(1) Since the TV camera protruding from the front pillar is small, there is no wind noise during running and there is no running resistance.

(2) The field of view of the three TV cameras can be divided correspondingly on the same display screen and displayed at the same time, which is very easy to see.

(3) Since the field of view immediately after the loading platform is displayed on the same display screen with one touch of a switch, it is possible to safely move backward.

(4) Even if the TV camera itself comes into contact with other things,
The flexible stay bends easily so that the TV camera is not damaged.

According to the present invention, since the TV camera is used, it is easy to reduce the size of the protruding portion and improve the appearance. In addition, the rear view taken by each TV camera is displayed on the image display screen arranged near the upper end of the center part of the windshield in the vehicle interior, so that it can be visually recognized with the same feeling as a conventional room mirror, and Since the images from each TV camera are concentrated on the display screen, the rear of the vehicle can be seen at a glance, providing excellent safety. Further, since the rear view of the vehicle captured by the rear TV camera is displayed only when the vehicle moves backward, unnecessary images are not displayed during normal traveling, which is also an advantage of being highly practical.
