Description

  The present invention relates to a fuel consumption display device.

  In general, a vehicle such as an automobile or a motorcycle is provided with a meter unit (display device) including a speed meter that displays the speed of the vehicle at a position that is highly visible to the driver. Usually, such a meter unit is provided with an odometer for displaying the total travel distance, a trip meter for displaying the travel distance and allowing the driver to arbitrarily reset in addition to the speed meter.

  In recent years, with the recognition of the importance of protecting the global environment, the reduction of automobile exhaust gas and fuel economy have attracted attention. Accordingly, it is common to know the fuel consumption of a running vehicle and use it as a guideline for fuel efficiency. User demands are also increasing. For this reason, the number of vehicles equipped with fuel consumption display devices is increasing.

  Various types of fuel consumption display devices have been proposed. For example, Patent Document 1 discloses a fuel consumption display device that displays fuel consumption numerically. In addition to numerical display, there is also a so-called bar graph fuel consumption display device. This is, for example, a display in which the number of areas having the luminance is one in the state with the lowest fuel consumption, and a display in which the number of areas having the luminance in the state with the highest fuel consumption is, for example, ten. Accordingly, the number of areas having luminance is changed.

Although it is configured to fall in the first liquid 31a, as shown in FIG. 2, the flow direction of the liquid fed by the circulation device 32 is set in the reverse direction, and the upper part inside the transparent container 31 is set. The accommodated first liquid 31 a may be circulated from the upper side to the lower side of the transparent container 31. When such a configuration is adopted, the fuel consumption amount display is performed so that the first liquid 31a having a small specific gravity led to the lower portion of the transparent container 31 floats upward in the second liquid 31b having a large specific gravity. The apparatus 1 can be configured. Even in such a configuration, the driver can easily recognize the amount of fuel actually consumed according to the running state (including the idling state) of a vehicle such as an automobile, The driver's consciousness to reduce the fuel consumption at the time works strongly on the driver, and it becomes easy to effectively perform fuel-saving driving.
