BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speed indicator for displaying traveling speed in various vehicles including fuel cell motorcycles equipped with a fuel cell.

As described in Patent Literature 1, a speed indicator for displaying a traveling speed is inserted into a dashboard of a four-wheeled vehicle or a motorcycle for road driving (hereinafter, collectively referred to as a car). .

An example of this kind of speed indicator is shown in FIG. The speed display system 1 includes a speed value display unit 2 in which numerical groups separated from each other at predetermined intervals are indicated by an arc shape, and an arc-shaped scale plate 3 in which a scale is formed by arranging the outer peripheral portion of the speed display unit 2. ) And a long guide 4 which is displaced corresponding to the traveling speed.

In the speed indicator 1 shown in FIG. 8, the numerical value group forms an order-of-order sequence of tolerance 20 with 0 as the first term and 160 as the final term. In the arc-shaped scale plate 3, an elongated scale 5 is formed at a point corresponding to a point where each numerical value of the numerical group is indicated and between the numerical values. On one side, a short scale 6 is formed in the middle of the long scales 5.

In addition, one end of the long needle part constituting the guideline 4 is positioned and fixed to the radial center of the arc-shaped scale plate 3. That is, the guide 4 is rotated and displaced in an arc shape along the arrangement of numerical groups and the arc-shaped scale plate 3 centered on the radius center of the arc-shaped scale plate 3.

When the vehicle is stopped, the tip of the guide 4 instructs the long scale 5 provided at a position corresponding to 0 of the numerical group in the arc-shaped scale plate 3. In addition, when the vehicle travels, the guideline 4 rotates in a displacement amount corresponding to the traveling speed. That is, for example, when the traveling speed is 40 km / h, the guideline 4 is displaced to the long scale 5 provided at a position corresponding to 40 of the numerical group in the arc-shaped scale plate 3. In addition, in the case of 55 km / h, the guideline 4 has a short scale 6 in the middle between the long scale 5 located in the middle of 40 and 60 and the long scale 5 provided at a position corresponding to 60. ), And this short scale 6 is indicated at the front-end | tip. The driver perceives the traveling speed of the vehicle by viewing the numerical value, the long scale 5 or the short scale 6 indicated by the guide 4 which is rotationally displaced in this way.

[Patent Document 1] Japanese Patent Application Laid-Open No. 2003-315107

As described above, the running speed of the vehicle is only perceived by viewing the position indicated by the instruction. For this reason, it is preferable that the speed indicator can easily recognize the position indicated by the instruction even at night and in other words, in other words, it is possible to grasp the traveling speed in a short time.

In recent years, from the standpoint of environmental protection, fuel cell vehicles equipped with fuel cells, electric vehicles equipped with motors and batteries, and the like have been put to practical use. However, in such vehicles, the remaining amount indicator indicating the remaining capacity of the fuel cells or batteries is used. You need to install In this case, when the remaining amount indicator is disposed at a place significantly separated from the speed indicator, there is a problem that it is not easy to grasp the running speed and the remaining capacity instantaneously just by turning the instrument panel.

In particular, in the case of a motorcycle, since the installation space of the dashboard is limited, it is necessary to make the dashboard itself dense, and therefore, the size of various display systems including the speed indicator is limited. In other words, it is necessary to provide a plurality of display systems in a space where the dashboard is limited, and therefore, it is required to have an arrangement in which the traveling speed and the remaining capacity can be grasped instantaneously.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and is excellent in visibility even when space is limited or at night. To this end, the present invention provides a speed indicator capable of instantaneously recognizing information such as traveling speed and battery remaining capacity. For the purpose of

In order to achieve the above object, the present invention is a speed indicator system that perceives the traveling speed by displacing the pointer corresponding to the traveling speed of the vehicle body,

A speed numerical value display unit which displays a numerical group constituting a predetermined equal order sequence and which can turn on or off the numerical group separately;

An area display portion disposed in the vicinity of the speed value display portion and lighting an area corresponding to the running speed of the vehicle body,

The pointer is displaced from the zero point of the speed value display unit as a starting point in accordance with the running speed of the vehicle body,

In the area display section, an area as much as the total displacement amount from the point 0 of the pointer to the current travel speed indicating point is emitted, and in the speed value display section, it is included in at least the range from the point O of the pointer to the present driving speed indicating point. It is characterized in that any one of the numerical group to be turned on.

That is, in the present invention, any one of the numerical values included in the numerical group exceeding the pointer is lit in the numerical group of the speed numerical value display portion. The discrimination by the visual recognition between the lighted numerical group and the lighted numerical group while being extinguished is very easy, thus making it easier to grasp the current traveling speed.

In the present invention, in addition to the lighting of this numerical value, the driving speed of the vehicle is displayed by the instruction by the pointer and the lighting of the area display unit. In other words, the current traveling speed is displayed by three kinds of display units. For this reason, according to this speed indicator, the driver can easily grasp the running speed simply by looking at the speed indicator. That is, this speed indicator is excellent in visibility.

In addition, when the numerical value rounded off the current traveling speed is larger than the current traveling speed, the numerical value closest to the current traveling speed instruction point of the pointer may be turned on in the speed value display section. That is, for example, when the current traveling speed is 47 km / h, "50" may be turned on, and when it is 96 km / h, "100" may be turned on.

Here, in the case where the vehicle is an electric vehicle that runs on the battery as a drive source, a battery information display portion for displaying whether the battery is in operation may be provided in the speed indicator. In this case, if the speed value display section, the area display section, and the battery information display section are displayed in an arc shape and these display sections are arranged concentrically, these display sections can be accommodated even in a narrow space. In other words, it is possible to avoid an increase in size of the speed indicator.

A fuel cell operation lamp indicating that the battery 12 is in an operating state is configured.

The numerical value group of the speed value display part 108 forms an equal order sequence of the first term 0, the term 120, and the tolerance 10. Of course, the numerical values are separated from each other at predetermined equal intervals.

Here, each numerical value is only the outer frame. In other words, the numerical group of the speed value display section 108 is provided as so-called external characters.

In the inner circumference of the second arc-shaped frame body 106, a scale extending toward the numerical value is provided at a position corresponding to the position of each numerical value of the speed numerical value display section 108. As shown in FIG.

When the ignition switch is rotated to the accessory (ACC) position, as shown in FIG. 5, the liquid crystal display 102 is positioned at the position corresponding to the zero point of the speed value display unit 108 under the control of the control unit. The pointer 140 appears to rotate with the center of rotation as the center of rotation. That is, in this embodiment, the pointer 140 is displayed on the liquid crystal display 102 as the liquid crystal cell lights up, whereby the driver can visually recognize the pointer 140.

At this time, in the liquid crystal display 102, the first region to the third region 130a to 130c of the first arc-shaped frame body 104, the numerical group of the speed numerical value display unit 108, and the frame for traveling distance display system.

In other words, the auxiliary battery regenerative lamp, the auxiliary battery discharge lamp, the fuel cell operation lamp 132, the numerical group of the speed value display unit 108, the traveling distance indicator, the left turn indicator, the right turn indicator, the coolant abnormal high temperature warning light, the coolant abnormal temperature low temperature warning light The hydrogen level indicator, the upper light warning lamp and the gas remaining warning lamp light up.

In addition to the above, the liquid crystal display 102 displays, on the inner circumferential side of the first arc-shaped frame 104, a decoration 142 composed of a decorative character and a figure imitating a battery. In addition, both of the trip meter 144 and the odd meter 146 are displayed below, and the time is displayed to the right of the odd meter 146.

When the ignition switch is further rotated, the fuel cell 12 is put into operation by the auxiliary operation of the auxiliary battery, and the fuel cell motorcycle 10 can be driven. At this time, if there is no error, the left turn indicator, the right turn indicator, the coolant abnormal high temperature warning light, the coolant abnormal low temperature warning light, the upper light warning light, and the remaining gas warning light are turned on.

6 shows a state in which the fuel cell motorcycle 10 starts to travel and the traveling speed reaches 35 km / h. As understood in FIG. 6, the pointer 140 is rotationally displaced along the inner circumference of the second arc-shaped frame body 106, and finally, is positioned between 30 and 40 on the speed value display unit 108.

In the liquid crystal display 102, the liquid crystal cell corresponding to the numerical value exceeded by the pointer 140 lights up. That is, in the state shown in FIG. 6, the liquid crystal cell corresponding to the location where 0, 10, 20, and 30 is marked lights up, whereby the inside of the frame body having a numerical value of 0, 10, 20, 30 It turns black. In either case, the liquid crystal cell corresponding to the numerical value after 40 remains off, in other words, the outline display remains as it is.

At the same time, in the liquid crystal cell corresponding to the inside of the second arc-shaped frame body 106, the tip of the pointer 140 at the position corresponding to the displacement amount of the pointer 140, that is, 0 of the speed value display section 108 The area up to this indicated position lights up.

In this way, the pointer 140 is arc-shaped along the speed value display unit 108 and the second arc-shaped frame body 106 (area display unit) to a position corresponding to the current traveling speed of the fuel cell motorcycle 10. Displacement by rotation. In the speed value display section 108, the numerical value exceeded by the pointer 140 displaced to a position corresponding to the current travel speed is colored. In addition, in the area display part, the area | region until the present position of the pointer 140, in other words, until it reaches | attains the position corresponding to a current traveling speed at zero point lights up in strip shape. In addition, the lighting or turning off of the liquid crystal cell by energization or stop of energization of the liquid crystal cell is performed under the control action of the controller.

As described above, the driver displays the current traveling speed by displaying the traveling speed on three types of display systems such as the position of the pointer 140, the color value display on the speed value display unit 108, and the band-shaped lighting display on the area display unit. It can be visually recognized easily and, as a result, it is possible to quickly grasp the current traveling speed.

In particular, in this embodiment, the liquid crystal cell of the location corresponding to the numerical value exceeded by the pointer 140 is turned on, and this numerical value is made to color. Thus, by coloring the numerical value which the pointer 140 exceeded, it becomes easy for a driver to distinguish from the numerical value with which the pointer 140 has not yet exceeded the outline display.

Further, the numerical values of the distance scale 112 and the capacity scale 120 are also turned on or off in accordance with the running distance and the residual amount of hydrogen gas. Therefore, the driver can also quickly obtain information on the distance that can be driven and the residual amount of hydrogen gas.

In the fuel cell motorcycle 10, only the fuel cell is driven during normal driving. In the state where only the fuel cell 12 is operating in this manner, the liquid crystal cell corresponding to the position in the frame body (third region 130c) of the fuel cell operation display system in the battery information display unit lights up.

In addition, when a significant load is added to the fuel cell 12, for example, when starting up or climbing a hill, the auxiliary battery starts to discharge. At this time, the liquid crystal cell corresponding to the position in the frame body (second region 130b) of the battery operation display system in the battery information display unit lights up.

In addition, when descending a hill, the secondary battery is charged under the action of the regenerative mechanism mounted on the fuel cell motorcycle 10. At this time, the corresponding liquid crystal cell in the frame body (first region 130a) of the battery regeneration display system in the battery information display unit lights up.

By turning on the liquid crystal cell as described above, the driver can recognize that the fuel cell is in the operating state, the auxiliary battery is in the discharged state, and the auxiliary battery is charged.

In this case, since the long needle part is not provided in the pointer 140, it is not necessary to position and fix one end of this pointer 140 in the center of the concentric circle, so that the battery information display part has a pointer ( It is not blocked at 140). That is, the driver can reliably perceive the information on the battery information display unit.

In the liquid crystal display 102, the liquid crystal cell is turned on at the corresponding position in the frame 118 for the hydrogen residual amount indicator, so that the remaining capacity of the hydrogen gas stored in the fuel spring 50 is displayed. On one side, the liquid crystal cell corresponding to the runable distance calculated from this residual amount of hydrogen gas lights up at a corresponding point in the frame 110 for runable distance indicator. As a result, the driver can grasp | ascertain the residual amount of hydrogen gas and the range which can be driven.

As described above, according to the present embodiment, the speed indicator 100 can be compactly arranged by arranging the battery information display portion, the speed numerical value display portion 108, and the region display portion in a concentric shape. In addition, the visibility of the battery information display section can be improved by not providing the needle section on the pointer 140.

Here, the numerical values of the trip meter 144 and the odd meter 146 rise with the traveling distance of the fuel cell motorcycle 10, while the display of the clock also changes with the progress of time.

Moreover, the liquid crystal cell corresponding to the inside of the frame body 114 for left turn indicators or the frame body 116 for right turn indicators lights, respectively, when a driver operates a direction instruction during a left turn or a right turn while driving.

Then, the coolant abnormality high temperature warning lamp is turned on when the temperature of the coolant circulated in the fuel cell 12 becomes equal to or higher than a predetermined value, for example, red color is displayed. On the other hand, a cooling water abnormality low temperature warning light turns on when the temperature of cooling water becomes below predetermined value, for example, it shows blue.

In addition, in the above-mentioned embodiment, although the liquid crystal cell of the location corresponding to the numerical value which the pointer 140 exceeded is made to light, even the numerical value which the pointer 140 did not exceed, the numerical value which rounded off the current traveling speed. The value closest to may be colored. For example, if the traveling speed is 35 km / h, as shown in Fig. 7, the rounded off 40 may be colored.

In addition, in this embodiment, although the speed display 100 with which the liquid crystal display 102 was assembled was illustrated and demonstrated, it is not limited to this specifically, but arrange | positions LED in the dashboard 38, and reflects to a reflective lens. The speed indicator may be a gradation display with a sense of depth such as a hologram.

In addition, a color filter may be combined with the liquid crystal cell to make the liquid crystal display a color display.

The speed indicator 100 according to the present embodiment is not limited to the fuel cell motorcycle 10, but may be a fuel cell four wheel vehicle. Of course, it may be a two-wheeled or four-wheeled vehicle that explodes a mixture of gas and air in the engine. In this case, since the battery information display section is unnecessary, a long needle section may be provided in the pointer 140, and the needle section may be fixed to the center of the concentric circles of the speed value display section 108 and the area display section. Of course, it may be an electric motorcycle or an electric four wheel vehicle on which a motor and a battery are mounted.

According to the present invention, in addition to the instruction by the pointer and the lighting of the area display unit, the numerical group exceeding the pointer in the numerical group of the speed numerical value display unit is turned on. For this reason, the driver can grasp the current traveling speed simply by turning his / her eyes even at a small size or at night.
