Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an integrated mileage display device capable of detecting and displaying an integrated mileage of a vehicle when a meter that digitally displays an integrated mileage loaded on a vehicle fails and the display becomes abnormal.
[0002]
[Prior art]
As shown in FIG. 4, a conventional vehicle loading meter 1 includes an integrated mileage display device 2 that displays the integrated mileage of the vehicle, and a drive control circuit 3 that drives the integrated mileage display device 2. Become.
[0003]
When the vehicle-mounted meter 1 fails, it may be necessary to investigate the accumulated mileage in order to determine whether the meter 1 has failed within the warranty period and to record the accumulated mileage in a maintenance notebook. is there.
[0004]
For this reason, by connecting the signal conversion interface board 4 to the fault meter 1, the integrated mileage data in the fault meter 1 is read and the integrated mileage is digitally displayed on the display 5. .
[0005]
Reference numeral 6 denotes a drive device such as a graphics controller, a SCSI controller, and a hard disk connected to the display 5.
[0006]
Japanese Utility Model Laid-Open No. 3-42450 discloses a technique similar to the above-mentioned conventional technique.
[0007]

Difficult and needs improvement.
[0008]
Further, it is conceivable to directly send the failure meter 1 to a parts manufacturer and investigate the accumulated mileage. However, the investigation time is lengthened, and the trouble of returning the failure meter 1 to the parts manufacturer every time a failure occurs, as well as the parts. There is also a risk that the cost of management man-hours will rise, such as the need for a manufacturing company to accept products, and improvements are desired in this regard.
[0009]
The present invention has been made in view of the above, and an object of the present invention is to provide an inexpensive and small-scale integrated mileage display device, thereby enabling permanent installation at a car sales base or a maintenance base, An object of the present invention is to provide an integrated mileage display device capable of shortening a period and reducing management cost man-hours.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, there is provided a connector which can be connected to an integrated mileage storage integrated circuit output terminal of a meter mounted on a vehicle, and a connector which is connected to the connector and integrates the meter. the cumulative running distance running distance storage integrated circuit outputs have a display means for digitally displaying, the display means, a switch that is connected to the connector, integrated travel distance storage of the meter by the oN signal of the switch The gist comprises a control circuit board for calculating the integrated travel control distance output by the integrated circuit, and a display device for displaying the integrated travel distance calculated by the control circuit board .
[0012]
According to a second aspect of the present invention, there is provided the integrated mileage display device according to the first aspect, wherein the display means does not include an integrated mileage storage integrated circuit, so that the integrated value of the vehicle-mounted meter can be obtained. The point is that the mileage can be displayed digitally as it is.
[0013]
【The invention's effect】
According to the first aspect of the present invention, a connector connectable to an integrated mileage storage integrated circuit output terminal of a meter mounted on an automobile, and an integrated mileage storage integrated circuit of the meter connected to the connector. Display means for digitally displaying the output mileage to be output, so that the data of the fault meter is displayed as the integrated mileage as it is, so that an inexpensive and small-scale integrated mileage display device is provided. Thus, a permanent installation can be made available at a car sales base or a maintenance base.
[0014]
When the switch is turned ON at the stage when the connector is connected to the fault meter, the control circuit board calculates the integrated travel control distance output by the integrated travel distance storage integrated circuit of the meter based on the ON signal, and the display device Thus, the integrated traveling distance calculated by the control circuit board can be displayed early and easily.
[0015]
Further, according to the present invention described in claim 2, in the display means, since not provided with the integrated travel distance storage integrated circuit, a directly digital capable of displaying accumulated running distance of an automobile loaded meter, inexpensive display The device can be provided.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0017]
FIG. 1 is an exploded perspective view of an integrated mileage display device according to an embodiment of the present invention, and FIG. 2 is a partial block circuit diagram showing a configuration of the integrated mileage display device of FIG.
[0018]
In FIGS. 1 and 2, reference numeral 10 denotes an integrated mileage display device of the present invention, and a connector 11 connectable to an integrated mileage storage integrated circuit output terminal (not shown) of the meter 1 mounted on an automobile; Display means 12 connected to the connector 11 for digitally displaying the integrated mileage output by the integrated mileage storage integrated circuit of the meter 1; and the display means 12 is a switch connected to the connector 11. 13, a control circuit board 14 for calculating an integrated travel control distance output by the integrated travel distance storage integrated circuit of the meter 1 based on the ON signal of the switch 13, and an integrated travel distance calculated by the control circuit board 14. It comprises a display device 15. 16 and 17 are cases that cover the control circuit board 14 and the display device 15.
