Abstract

PURPOSE:To improve visibility, by providing two flexible transparent plates, providing a variable restrictor, which controls the amount of transparent liquid in said transparent plates, deforms the transparent plates as covers for the instruments of a vehicle. CONSTITUTION:The inside of instrument covers 2a are connected to a pump 5 and a tank 6 for storing non-reflecting transparent liquid 2a through a pipe 3. A variable constrictor 4 is provided on the pipe 3 between the instrument covers 2 and the pump 5. When a switch 7 is turned ON, a motor 8 is started and the pump 5 is driven, the liquid 2a in the tank 6 is supplied to the inside of the instrument covers 2. Therefore, the liquid 2a in the instrument covers 2 is increased and the refractive index is provided as a convex lens. Said refractive index is adjusted by the variable constrictor 4. Thus the instrument coves having the refractive index corresponding to the visual acuity of a driver can be obtained.

Description

[Detailed description of the invention] <Technical field of invention> The invention relates to a vehicle instrument panel.

<Prior art and its problems> Conventional instrument panels for automobiles and other vehicles generally read information without moving your face to improve visibility.

The range where the vehicle can be viewed is within 30' from the left and right in terms of line of sight, and especially high-speed speedometers, tachometers, etc. are located within 10' from the left and right.

However, conventional vehicle instrument panels do not take the driver's visual acuity into account, and have the disadvantage of poor visibility for nearsighted, elderly, and tilted drivers.

<Object of the Invention> In view of the drawbacks of the above-mentioned conventional examples, an object of the present invention is to provide a vehicle instrument panel that can improve visibility according to the visual acuity of the driver.

<Structure and Effects of the Invention> In order to achieve the above objects, the present invention includes two flexible transparent plates and controlling the amount of transparent liquid in the transparent plates. and a variable diaphragm that controls the refractive index by deforming the transparent plate, and the transparent plate is used as a cover for a vehicle instrument.

Therefore, according to the present invention, the refractive index of the instrument cover can be changed according to the visual acuity of the driver, thereby improving visibility.

<Embodiments of the invention> The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an embodiment of the present invention, and numeral 1 indicates a conventional automobile meter.

An instrument cover 2 formed of two flexible transparent plates is arranged at the front part 1& of the instrument 1. Inside the instrument cover 2, a pump (P) 5 and a non-reflective transparent liquid 2 are supplied through a conduit 3.
It is connected to a tank 6 for storing a. The conduit 3 between the instrument cover 2 and the pump 5 is provided with a variable choke 4. 7 is a switch (SW) for starting the motor (M) 8 .

FIG. 2(a) is a sectional view of the instrument cover 2 taken along the line ■-■, and is filled with a small amount of liquid 2a so that the two transparent plates of the instrument cover 2 are parallel to each other.

In this case there is no refractive index of the instrument cover 2.

In the above configuration, when the switch 7 is turned ON to start the motor 8 and drive the pump 5, the liquid 2a in the tank 6 is
is fed into the instrument cover 2 through a conduit 3. Therefore, as shown in FIG. 2(b), the amount of liquid 2a in one instrument cover 2 is increased so that it has the refractive index of a convex lens. Since this refractive index can be adjusted by the variable diaphragm 94 provided in the conduit 3, it is possible to obtain an instrument cover with a refractive index that corresponds to the visual acuity of the driver.

In the embodiment 911, the instrument cover 2 is configured to have a refractive index as a convex lens, but it may be configured to have a refractive index as a concave lens. Furthermore, although a 1@ variable aperture is used as a refractive index control means for the instrument cover, it may be provided for each instrument cover corresponding to each instrument.
