Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a vehicle traveling display device,
More specifically, the movable plate on the hood (engine hood) is lifted by negative pressure depending on the running speed of the car,
The present invention relates to a traveling display device for an automobile, which exposes a display section and displays some kind of information such as an overspeed to a driver.

[Prior Art] Generally, when driving a car, it is necessary to be careful not to overspeed, and dozing due to monotonous speed such as running on a highway, misrecognition of speed, or boring passengers It will happen.

Therefore, conventionally, the speed control is basically performed by the driver himself / herself by a speedometer, and there is a device for warning at a constant speed by a buzzer or a chime for high speed traveling.

Also, to prevent monotonous driving, listening to radio or music is performed.

[Problems to be Solved by the Invention] A conventional warning device using a buzzer or the like is completely useless for traveling in an urban area, and the driver must always control the speed by a speedometer.

Also, listening to the radio and the like is always continued while driving, and the effect of preventing monotonous driving is small.

The present invention has been made in view of the above problems of the conventional technology. The purpose of the present invention is to enable the driver to freely use it according to his / her skill and running condition. It is an object of the present invention to provide a traveling display device for an automobile, which is capable of calling attention without moving the line of sight, has the unexpectedness of visually appealing at a desired speed, and can be easily and inexpensively implemented.

[Means for Solving the Problems] In order to achieve the above object, a vehicle traveling display device according to the present invention includes a substrate having locking means for detachably attaching to a hood of an automobile, and the substrate. The movable plate has one end rotatably attached, and a display unit arranged on the movable plate. The movable plate is lifted by negative pressure on the bonnet generated by traveling of the automobile. It is a thing.

[Operation] It is known that when a car runs, negative pressure is generated on the hood due to air resistance (literally, "Aesthetics of automobiles" published by Kobunsha or "Transportation mechanical engineering" published by Sankaido Co., Ltd., etc. It is described in).

As shown by the size of the arrow in FIG. 6, the negative pressure (suction force) generated on the bonnet is slightly large at the front part of the bonnet and gradually becomes smaller toward the rear part, and this negative pressure becomes positive pressure. It is also known to have a large value in comparison.

The board can be freely attached and detached on the bonnet by the locking means, and the board is fixed on the bonnet if necessary. If a predetermined negative pressure is generated by running, the free end of the movable plate rotates and opens. Lifted and lifted.

That is, the positive pressure or weight acting on the movable plate is overcome by the suction force due to the negative pressure, and the free end on the driver side, which is the rear portion of the movable plate, rises.

Then, due to the rise, the display portion arranged at the overlapping portion of the substrate and the movable plate is exposed, and the driver and passengers can see the characters and figures on the display portion without diverting their eyes from the front direction of the vehicle. Is something that can be done.

[Examples] Examples will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, and is a perspective view of a main part showing a state in which a movable plate is lifted and a display part is exposed.
Similarly, the figure is a side view of essential parts showing a state where the movable plate is lifted by traveling of the vehicle.

Reference numeral 1 is a substrate made of a rubber magnet, and the substrate 1 has appropriate flexibility so as to easily conform to the curved surface of the hood 6 of an automobile, and is attachable to and detachable from the bonnet 6 by its magnetic force.

Reference numeral 2 denotes a movable plate made of a thin plate-like synthetic resin. The movable plate 2 has a fixed end portion 4 adhered to the substrate 1 and a fold line 5 is provided thereon. It is attached so that it can rotate freely (open and close freely) and can be lifted at a speed of about 50 km / h for city driving.

Reference numeral 3 is a display portion made of an extremely thin synthetic resin.
Has one end attached to the free end of the movable plate 2 and the other end attached to the substrate 1, respectively, and the surface of which is marked with a letter indicating that the speed is too high.

The display unit 3 is formed so that it can be folded in two by opening and closing the movable plate 2.

3 to 5 show another embodiment of the present invention, and 7 is a substrate made of a rubber magnet and a synthetic resin.

Reference numeral 8 denotes a movable plate rotatably attached to the base plate 7 by a hinge-shaped fixed end portion 10. The movable plate 8 has a curved shape in order to promote more negative pressure and facilitate lifting. It is formed on (Cumber) and lifts at about 40 km / h.

Reference numeral 9 denotes a display unit that can be folded, and the display unit 9 displays characters (not shown) such as characters and animals that warn against excessive speed.

The present invention is not limited to the above-described embodiment, and for example, the substrate may be in a form and color that can be used as a novice mark in combination with the movable plate, and the locking means may be a permanent member. It may be a magnet or a suction cup.

Further, the display portion may be provided on the back surface (overlapping surface with the substrate) of the movable plate, or the display portion may be exposed in the side direction so that it can be recognized from the outside of the vehicle.

Furthermore, the characters on the display may be displayed with a color-developing agent such as fluorescent paint, and the display can be replaced so that it can be adapted to the age of newcomers and passengers. Good.

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects.

Since the display unit is exposed on the hood which is the front field of view of the driver or passenger, the contents of the display unit can be safely notified with little movement of the line of sight.

In addition, the contents of the display can be freely selected such as letters and figures, and due to the unexpectedness exposed by hoisting while driving, the driver should be careful about safe driving and the passengers should be provided with entertainment. You can

Further, since the structure is simple and can be provided at a low cost, and is detachable, it has an effect that it can be used freely depending on the driving skill, the traveling place and the like.
