[0001]

[Industrial applications]

 The present invention relates to a device for preventing forgetting to close a fuel cap of an automobile.

[0002]

[Prior art]

 As shown in FIG. 4, the fuel injection port of the automobile has a fuel saucer c attached to the inside of an opening b 1 provided in the body outer plate a and a fuel cuff that opens and closes the opening b of the body outer plate a. The fuel lid is opened by opening the fuel lid d and the cap f at the end of the filler pipe e projecting into the fuel source c. The fuel injection gun is inserted into the filler pipe to inject fuel. When the fuel injection is completed, the cap f is screwed into the filler pipe e and the fuel lid d is closed to inject the fuel into the fuel tank. In this case, in order not to forget to close the fuel lid d and to start the vehicle, a switch s that is turned on / off according to the opening / closing of the fuel lid d is provided. If the fuel lid d is not completely closed, the buzzer is Is sounded to warn the driver or the engine cannot be started (see, for example, Japanese Utility Model Publication No. 2-117226).

[0003]

[Problems to be solved by the device]

 However, when fuel injection is completed, the fuel lid may be closed without forgetting to close the cap. However, since the conventional switch s cannot detect the forgetting to close the cap, even the fuel lid is not detected. If closed, the engine can be started without issuing a warning, and there is a risk that the engine may start without noticing that the cap has been forgotten to be closed.

The present invention aims to address the above-mentioned conventional problems.

[0005]

[Means for Solving the Problems] In the present invention, in the fuel injection portion of an automobile as described above, a fuel switch is provided on an inner surface of a fuel lid, and an operating piece thereof faces a fuel cap mounted on a filler pipe. When the fuel lid is fully closed, the operating piece of the fuel switch is configured to operate by being pressed against the fuel cap, and when the operating piece is not operating, the fuel switch operates. A first feature is that a warning device is activated to give a warning to a driver by issuing a detection signal for forgetting to close the lid and the fuel cap, and a half-door warning lamp originally installed in an automobile as the warning device. The second feature is that the circuit's half-door warning lamp is shared, and it has a half-door warning lamp for each front, rear, left, and right doors. For motor vehicles, the door ajar warning lamp for the right and left rear door in which a third feature in that sharing as the warning device.

[0006]

[Action]

 With the above configuration, not only when the fuel lid is forgotten to be closed, but also when the fuel lid is fully closed and the filler cap is not attached to the filler pipe, the operating piece of the fuel switch operates. Instead, the fuel switch issues a signal to detect that the fuel lid and fuel cap have not been closed and activates the warning device to warn the driver. A fuel switch and fuel cap can be activated with one fuel switch. It is possible to solve the conventional problem that the fuel lid may be closed without attaching the fuel cap after the fuel injection, by detecting the forgetting to close both of them. Also, by commonly using the half-door warning lamp that has been generally equipped as the above-mentioned warning device, or in the case of a car having a half-door warning lamp for each of the front, rear, left and right doors, the half-door warning lamp for the left and right rear doors By sharing the above as a warning device, the warning circuit for not forgetting to close the fuel lid and the fuel cap can be remarkably simplified and the cost can be reduced accordingly.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, 1 is an automobile body outer plate, 2 is a fuel sorcer, and by fixing the fuel sorcer 2 to the inside of the opening provided in the body outer plate 1, the recess 3 is formed. The front surface of the recessed portion 3 can be opened and closed by being provided at a predetermined position of the body outer plate 1 and by mounting the fuel lid 4 in the opening portion of the body outer plate 1. The tip of the filler pipe 5 projects into the concave portion 3 and the fuel inlet at the tip of the filler pipe 5 is arranged so as to face the inside of the fuel lid 4 in the closed position. The entrance is closed by mounting a fuel cap 6. In FIG. 1B, 4a is a hinge arm of the fuel lid 4.

The structure of the fuel injection section is the same as the conventional one, but in the present invention, the fuel switch 7 is attached to the inner surface of the fuel lid 4 so as to face the fuel cap 6, and the fuel lid 4 is attached. When fully closed, the operating piece 7a of the fuel switch 7 directly contacts the fuel cap 6 and is pressed to be turned off (or turned on).

With the above configuration, when the fuel lid 4 is forgotten to be closed, the operating piece 7a of the fuel switch 7 is not pressed and the fuel cap is closed even if the fuel lid 4 is fully closed. If 6 is not attached, the operating piece 7a will not be pressed, so the fuel switch 7 will not be turned off (or turned on), and therefore one fuel switch 7 will fail to close the fuel lid 4 and the fuel will not be closed. Both the forgetting to attach the cap 6 can be detected.

In FIG. 1, reference numeral 8 denotes a switch harness of the fuel switch 7, and the switch harness 8 electrically connects a warning device and other devices that make it impossible to start the engine and the fuel switch 7 described above. When connected and either or both of the fuel lid 4 and the fuel cap 6 are not closed, the driver is warned or the engine cannot be started.

FIG. 2 is a circuit diagram showing an example of the above-mentioned warning device, and an example in which a half-door warning lamp that warns a half-latch of a door is shared as a forget-for-warning device for closing the fuel lid and the fuel cap. Shows.

That is, in FIG. 2, 10 is a half-door warning lamp circuit that has been generally used conventionally, and the half-door warning lamp circuit 10 is basically a door switch 11 for detecting opening and closing of a door and a half-door warning lamp circuit. It consists of the door warning lamp 12, and the door switch 11 is turned on except when the door is completely closed (full latch state), and the circuit from the battery 13, the half door warning lamp 12, and the door switch 11 to the ground is closed. The half door warning lamp 12 lights up to warn that the door is not completely closed. When the door is completely closed, the door switch 11 is turned off and the half door warning lamp 12 is turned off.

By using the half-door warning lamp circuit 10 and connecting the fuel switch 7 shown in FIG. 1 in parallel with the door switch 11, the half-door warning lamp 12 is turned on to turn off the half-door warning lamp. It is designed to warn the driver of forgetting to close the fuel lid 4 and the fuel cap 6.

In an automobile, the frequency of fuel injection is generally low compared to the frequency of opening and closing the door, and thus it is necessary to provide a dedicated warning device for warning the fuel injection section that is extremely infrequently used. Not only is there a cost disadvantage, but there is also a problem in terms of the installation space for the warning device. Therefore, by sharing the half-door warning lamp originally installed in the vehicle as the warning lamp of the fuel injection section as described above, the half-door warning lamp 12 is turned on during normal operation except when fuel is injected. It can be recognized that it is a warning of, and only after the fuel injection, the half-door warning lamp 12 is turned on to check both the door and the fuel injection part. However, as mentioned above, the frequency is extremely low and both Since both checks are performed before the start of the vehicle, it does not place much burden on the driver and can fully perform the intended function.

In the embodiment of FIG. 2, for example, the half-door warning lamp 12 is adapted to be turned on when any one of the plurality of doors is not completely closed. An example of combining the user switch 7 is shown, but in the case of a half-door warning lamp circuit that is equipped with a half-door warning lamp for each door so that it can be checked at a glance which door is not completely closed As shown in Fig. 3, the left and right rear door half-door warning lamps are also used for warning the fuel injection section.

That is, in FIG. 3, the door switch 11 is composed of front right and left door switches FRsw and FLsw and rear right and left door switches RRsw and RLsw. In some cases, the rear gate door switch RGsw is It may be added. The half-door warning lamps 12a, 12b, 12c, 12d, 12e are connected to each of these switches, and all the switches are turned on when the door is completely closed, and are constituted by switches that are turned off when the door is completely closed. When it is not completely closed, the door switch is turned off and the half door warning lamp connected to the switch is turned on to give a warning. In this way, the fuel switch 7 shown in FIG. 1 is connected in parallel to the rear right and left door switches RRsw and RLsw of the half-door warning lamp circuit 10 having the half-door warning lamp for each door, and the fuel lid is connected. When either one or both of 4 and the fuel cap 6 are open, the fuel switch 7 is turned off and the half door warning lamps 12c and 12d for the right and left rear doors are configured to be turned on. .

In the case of automobiles, there are overwhelmingly many cases where one driver gets in and two cases where a driver and a passenger occupy a passenger, and there are relatively few cases where three or more people get in. Furthermore, even in the case of three-seater passengers, the rear-seat passengers usually get on and off from one of the left and right rear doors, and when four-passengers get on and off the road, only one rear door is used. . Therefore, there are very few cases where both left and right rear doors are used to get on and off, and the probability that both left and right rear doors are half doors when the vehicle starts is extremely small. Therefore, as shown in FIG. 3, if the left and right rear door half-door warning lamps 12c and 12d are also used for warning the fuel injection portion, the left and right rear door half-door warning lamps will be activated when the vehicle starts after fuel injection. If both are lit, it is almost certain that it is judged that either one or both of the fuel lid 4 and the fuel cap 6 has been forgotten to be closed.

In FIG. 3, 14 is an inverter, and 15 is an OR circuit.

[Effect of device]

 As described above, according to the present invention, it is possible to detect both the forgetting to close the fuel lid and the forgetting to put on the fuel cap at the same time with one fuel switch, and the fuel can be attached without wearing the fuel cap. It is extremely effective because it completely eliminates the danger of starting without noticing that the lid has been closed. Furthermore, the fuel switch described above is connected in parallel to the door switch of the half-door warning lamp circuit that has been generally equipped in the past, and the half-door warning lamp is shared as the fuel lid and the forget-to-close warning lamp of the fuel cap. By doing so, it is possible to reduce costs by sharing parts and circuits, and it is possible to bring great effects in practical use.
