Abstract

(57) [Summary] An indicator installed in the instrument panel and an optical component for displaying the corner-pole-shaped virtual image displayed by the indicator on the corner of the vehicle are installed and viewed from the driver's seat. An object of the present invention is to provide a vehicle corner position display device capable of visually confirming the vehicle corner position by a virtual image.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corner position display device for a vehicle body that allows the front corner position, the rear corner position, etc. of an automobile to be easily confirmed from the driver's seat.

[0002]

[Prior art]

 As a conventional vehicle corner position display device, for example, as shown in FIG. 1, a control pole 3 is erected at a corner portion of a front bumper 2 of an automobile 1, a front portion of a fender, or the like so that the vehicle can be driven from a driver's seat. The position of the front bumper 2, that is, the position of the front bumper 2 is roughly known.

[0003]

[Problems to be solved by the device]

 However, since the vehicle driver's view is obstructed by the hood of the vehicle, the base portion of the control pole 3, that is, the mounting portion of the bumper 2 cannot be seen from the driver's seat, and therefore the control pole 3 is not visible. Driving is performed with the feeling that the position of the tip of the vehicle is used as a reference.

Therefore, in a vehicle that is difficult to drive, a vehicle with a high bonnet, or the like, the distance between the front bonnet and the end surface of the vehicle and an obstacle, such as a building or a preceding vehicle, is extremely narrow. There is a problem in that it is difficult to accurately measure the distance between the two from the driver's seat, and this may cause an accident such as damage to the vehicle or obstacles.

In addition, there is a problem in that when the control pole 3 is mounted on the vehicle body, the mounting work, the wiring work and the like are troublesome and the economy is low.

[0006]

[Means for Solving the Problems]

 The present invention has been made by paying attention to such a conventional problem, and displays a display incorporated in an instrument panel and a corner-pole-shaped virtual image displayed by the display at a corner of a vehicle. (EN) An optical component is provided to provide a vehicle corner position display device capable of visually confirming the vehicle corner positions viewed from the driver's seat by a virtual image.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

In FIG. 2, a vehicle body 11 is equipped with a hood 12, a front bumper 13, a windshield 14, and an instrument panel 15. Inside the instrument panel 15, a light emitting indicator 16 for producing a corner pole-shaped display and an optical component (concave mirror) for reflecting the display image emitted from the light emitting indicator 16 on the windshield surface. ) 17 is incorporated. A part of the inner surface of the windshield 14 is a translucent reflector for receiving a display image reflected by the optical component 17 and displaying it as a virtual image 18 at a front corner (corner) of the vehicle body 11. The (combiner) 19 is attached. 20 indicates the driver's eye point.

The structure of the present embodiment is as described above. Next, the operation thereof will be described. Driving the display now causes a corner-pole-shaped light emission display, and this light emission display image is displayed on the optical component 17. Then, the light-emitting display image (corner-shaped) is reflected by the translucent reflection plate 19 and is displayed as a virtual image in the front direction of the vehicle body by the translucent reflection plate 19.

According to the present invention, the display position of the virtual image 18 is positioned at the corner position of the vehicle body as shown in FIG. 3, so that it looks as if a corner pole is provided at the corner position of the vehicle body. Therefore, it is possible to prevent the collision of the vehicle by driving while confirming the virtual image position.

Therefore, in order to position this virtual image display position at the front corner of the vehicle body 11, it depends on the distance from the display surface of the display 16 to the translucent reflector 19, and the following calculation is performed. The formula holds.

That is, the distance from the display surface of the display to the reflective surface of the optical component 17 is a, the distance from the reflective surface of the optical component 17 to the reflective surface of the translucent reflector 19 is b, and the magnification of the optical component 17 is Is m, and c is the distance from the surface of the windshield 14 to which the translucent reflector 19 is attached to the display position of the virtual image 18, then a × m + b = c.

Therefore, after the value of c is obtained by actual measurement of the vehicle body or separately calculated (Pythagorean theorem), the known number of this c and any two known numbers of other a, m and b are used in the above formula. By substituting, the set positions of the display 16 and the optical component 17 can be calculated.

As described above, in this embodiment, the corner-pole-shaped virtual image displayed by the head-up display means, that is, the display 16, the optical component 17, and the translucent reflector 19 is displayed on the outer corner of the vehicle. Since it is possible to display the position on the vehicle, it is extremely easy to check the front corner position of the vehicle without using a conventional corner pole, and thus it is possible to prevent contact accidents or damage accidents of the vehicle. .

In the present embodiment, the virtual image of the corner pole shape is displayed at the front corner position of the vehicle body, but the present invention is not limited to this, and for example, an equivalent display device in the rear parcel shelf. It is also possible to display a corner-pole-shaped virtual image at the rear corner of the vehicle body by installing the interior and attaching a translucent reflector to the rear window.

[0016]

[Effect of device]

 As described above, according to the present invention, the vehicle body 11 is provided with a display 16 for displaying a corner pole shape, and a display image from the display 16 is reflected on the windshield or the rear glass of the vehicle so as to be displayed on the outer corner of the vehicle. Since the corner position display device of the vehicle body is provided with the optical component 17 and the translucent reflection plate 19 for displaying the virtual image, according to this, the display 16 and the optical component 17 and the translucent reflection plate 19 are displayed. Since a corner-pole-shaped virtual image can be displayed at the outer corner of the vehicle, the front corner position of the vehicle can be checked very easily without using a conventional corner pole, which can lead to a car accident or damage. The effect is that it can be prevented.
