Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a display mechanism such as a speedometer that detects the running speed of a vehicle and displays the detected speed in steps of predetermined speed units.

[Conventional technical background and its problems]

Conventionally, devices that display vehicle running speed, etc., have processed electrical signals corresponding to changes in measured quantities through circuits, and then energized an ammeter, similar to a moving coil meter, to correspond to the indicated rotation position of a pointer. A common configuration is to read the scale.

However, when the above-mentioned guideline-based indication method is installed in a vehicle with strong vibrations, it is easy to cause indication failures such as needle vibration, and it is necessary to take preventive measures such as using buffer oil. It has the disadvantage of hindering the

In recent years, the display system of this type of device has tended to shift to a bar-shaped display device as shown in FIG. 1, for example, in order to eliminate the above-mentioned drawbacks, increase precision, and improve visibility.

The above-mentioned bar-shaped display method using LED, LCD, or fluorescent display tubes allows extremely high precision display by setting the minimum display unit, and allows selection of soft color combinations that do not stimulate the visual sense.
Suitable for analog display with good visibility.

Incidentally, the continuous strip-like arrangement of the fine segments can accurately display minute changes in speed, but while driving a vehicle, checking the surroundings is the main focus, and it is desirable for safety reasons to be able to grasp the driving speed at a glance. In particular, for a speedometer mounted on a small motorcycle or other convenient means of transportation in daily life, there is almost no need to grasp the exact driving speed, and if you can glance at it and confirm that you are within the safe driving range, the function of a low-speed driving vehicle is fully satisfactory. Furthermore, for speedometers mounted on long-distance transportation means such as high-speed vehicles such as automobiles, it is possible to grasp the driving speed more accurately with a digital display, and it can be said that adding a display function that allows you to confirm the approximate speed at a glance is sufficient as a guide for stable driving.

[Purpose of invention]

The purpose of this invention is to divide the entire display range of a speedometer or other display section mounted on a running vehicle into a plurality of parts, arrange them at a distance, and further divide each display block into arbitrary display units according to its importance. The purpose is to provide a display device with good visibility by partitioning the display device into sections.

[Means for solving problems]

In order to achieve the above object, this invention divides the entire display range of an arbitrary measured quantity into a plurality of display blocks, which are arranged at predetermined intervals, and which display blocks are divided into different blocks according to their importance. A display element that is divided into a plurality of display units is provided, and the display block is divided into predetermined shapes corresponding to the display units.

〔Example〕

An embodiment of the present invention will be described in detail based on FIG. For example, in order to detect and display the running speed of a small motorcycle, the rotation of the vehicle is extracted as an electrical signal using an electromagnetic pickup, etc., the waveform is shaped, and then counted at regular intervals by a counter.
LEDs arranged into arbitrary display units through decoder
This can be easily achieved by applying a voltage to a display element such as .

The display range of the present invention has a configuration in which the entire display range is divided into a plurality of display blocks and arranged separately.In other words, the speed display panel 1 has a total display range of 60 km/h in units of 10 km/h. The display blocks ₃₁ to 36 divided into _six are spaced apart from each other in two stages.

The display blocks 3 ₁ to 3 ₆ are each subdivided into different display units, and are partitioned into a predetermined shape with a corresponding number of display elements (for example, LEDs with color display), so that the display blocks 3 1 to 3 6 are divided into sections in a predetermined shape with a corresponding number of display elements (for example, LEDs that display a color display). Display blocks 3 ₁ to 3 ₆ for low-speed and high-speed regions where there is little need to confirm changes, i.e., are of low importance, are divided into two by display elements A and B with a display unit of 5 km/h, and display blocks 31 to 36 are divided into two by display elements A and B with a display unit of 5 km/h. In the middle speed range of 20 km/h to 40 km/h, which is important for many people to check their driving speed relatively frequently, display blocks 3 ₃ and 3 ₄ are display elements with display units of 2 km/h. Divide into 5 by A, B, C, D, E,
The display blocks ₃₂ and 35 whose driving opportunities are between the _{display blocks 31 and 36 and the display blocks 33 and 34 are display elements A} , B, and the display units whose display unit is approximately 3 km/h. The screen is divided into three parts by C, and the entire display range is divided into display units according to the importance of each display block.

If the vehicle is currently traveling at a speed of 24 km/h, all display elements in display blocks 3 ₁ and 3 ₂ will light up, and display elements A and B in display blocks 3 ₃ will also light up to indicate the current traveling speed. Display. Therefore, the driver can intuitively read the current driving speed by looking at the number of light emitted from the display blocks ₃₁ to ₃₆ placed apart from each other, and can always keep his/her eyes focused on the surrounding situation, thereby improving safe driving. However, it is extremely effective, and since important display blocks are divided into display units finely, speed changes can be grasped more accurately.

In addition, the speed change in the medium speed range in this case is
The shape is such that it can be identified by increasing or decreasing the light emitting display area, but by dividing the display block into smaller display elements, the basic shape such as a square is divided into broken shapes, making it easier to read the running speed. becomes.

[Effect of idea]

In this way, the present invention divides the entire display range of any measured quantity into a plurality of display blocks, which are spaced apart at predetermined intervals, and divides each of these display blocks into different display units according to its importance. By providing a display element and arranging the display block to be divided into a predetermined shape corresponding to the display element, it is possible to provide a display with extremely good visibility at a low cost without complicating a drive circuit. Moreover, since the display unit of the important element display block is divided into fine sections, the display contents can be easily grasped.
