Description

The present invention relates to a fuel lid opener circuit that electrically opens a fuel lid that covers a fuel filler port of a vehicle or the like powered by an internal combustion engine.

(Prior Art) For example, in a motorcycle, a fuel filler port of a fuel tank is provided at an uppermost portion of the fuel tank. When the fuel tank is arranged below the seat, the fuel filler port of the fuel tank may be located at the rearmost part of the fuel tank, that is, at the rearmost part of the entire motorcycle.

The fuel filler is provided with a lockable fuel lid that covers the entire fuel filler in order to prevent mischief. Fuel is supplied by opening the fuel lid.

The fuel lid opener circuit for opening the fuel lid is configured as shown in FIG.
The fuel lid opener circuit 1 shown in FIG.
An ignition switch 2 having three positions of "N", "FUEL" and "OFF" is provided. When the ignition switch 2 is set to the “ON” position during normal running of the motorcycle, the horn circuit 6 is electrically connected in the order of power supply 3 → ignition switch 2 → horn 4 → horn switch 5 → power supply 3. And a horn switch 5
Pressing causes the horn 4 to sound.

The “FUEL” position of the ignition switch 2 is
This is a position that constitutes a fuel lid opener circuit 1 that opens a fuel lid that covers a fuel filler port of a fuel tank when fueling a motorcycle. The fuel lid opener circuit 1 is electrically connected in the order of a power supply 3 → an ignition switch 2 → a fuel opener solenoid 7 → a fuel opener switch 8 → a power supply 3. When the fuel opener switch 8 is pressed, the fuel lid 7 locks the fuel lid. And release the fuel lid.

The "OFF" position is a position when the motorcycle is not used, and the power supply 3 is not connected to any circuit.

(Problems to be Solved by the Invention) However, the conventional fuel lid opener circuit 1 is independent of the horn circuit 6 that sounds the horn 4, and it is necessary to provide the fuel opener switch 8 separately from the horn switch 5. The fuel opener switch 8 could not be provided on the handle portion due to restrictions on the mounting space. For this reason, the motorcycle occupant must release his / her hand from the steering wheel in order to depress the fuel opener switch 8, and in practice, the occupant must step down from the motorcycle each time to release the fuel opener switch 8. Is pressed. Further, since the fuel opener switch 8 is provided independently, the mounting becomes complicated, the number of parts increases, the cost increases, and the appearance of the motorcycle is impaired.

The present invention has been made in view of the above problems, and can open the fuel lid with a simple operation, and,
It is an object of the present invention to provide a fuel lid opener circuit that can reduce the cost by using a fuel opener switch also as another switch and improve the aesthetic appearance.

[Configuration of the invention]

(Means for Solving the Problems) In order to achieve the above object, a fuel lid opener circuit according to the present invention includes a fuel tank in which a fuel filler port is covered with a fuel lid that can be opened and closed, wherein an opener switch and a horn for the fuel lid are provided. The horn switch is also used as a handle switch linked to the position of the ignition switch, and the fuel lid is opened by operating the handle switch with the ignition switch set to the fuel position. is there.

(Function) According to the present invention, the opening of the fuel lid can be performed by the handle switch at hand of the occupant, so that the operation of the occupant is simplified. Further, the fuel opener switch is omitted, so that the cost is reduced and the aesthetic appearance is reduced. Can contribute to the improvement of

Hereinafter, an embodiment of a fuel lid opener circuit according to the present invention will be described with reference to the drawings.

FIG. 1 shows a fuel lid opener circuit 10 according to the present invention. This fuel lid opener circuit
10 applies to all vehicles powered by internal combustion engines,
FIG. 2 shows an example applied to a motorcycle.

This motorcycle has a head pipe as shown in FIG.
In general, an engine unit 13 is mounted below a main tube 12 extending rearward from 11, and a seat 15 is placed on a seat rail 14 extending further rearward and upward from a rear portion of the main tube. In the motorcycle, when a storage box 17 capable of storing a large object such as a helmet 16 is disposed above the main tube 12, a layout in which a fuel tank 18 is provided below the seat 15 is adopted.

The fuel supply port of the fuel tank 18 must be provided near the uppermost portion of the fuel tank 18, but when the fuel tank 18 is arranged below the seat 15 as shown in FIG.
Is extended upward, so the filler port 20 is
, That is, near the rear end of the entire motorcycle.

This filler port 20 has a filler port to prevent tampering.
A fuel lid 21 with a lock that covers the whole 20 is provided, and fuel is supplied by opening the fuel lid 21.

The fuel lid 21 is opened by a fuel lid opener mechanism 22 as shown in FIG. The opener mechanism 22 includes an opening spring 23 that constantly biases the fuel lid 21 toward the open position and a fuel lid 21.
And a lock mechanism 24 for holding the lock mechanism in the closed position. The lock mechanism 24 includes a lock claw 25 provided on the fuel lid 21 and a lock lever 26 that can be engaged with the lock claw 25.
And a lock spring 28 that constantly biases the lock lever 26 toward the lock position side, and the lock lever 26 is actuated by the operation of the fuel opener solenoid 27. It rotates around the fulcrum P against the spring force of the lock spring 28, and is operated to the open position.

On the other hand, as shown in FIG. 1, the fuel lid opener circuit 10 for opening the fuel lid 21
An ignition switch 30 having three positions of “N”, “FUEL”, and “OFF” is provided. The "ON" position of the ignition switch 30 is a position during normal running of the motorcycle, and the circuit is connected in the order of power supply 31 → ignition switch 30 → horn 32 → ignition switch 30 → handle switch 33 → power supply 31. And a horn circuit 34. In this horn circuit 34, pressing the handle switch 33 causes the horn 32 to sound.

The “FUEL” position is a position that constitutes a fuel lid opener circuit 10 for opening a fuel lid 21 that covers a fuel filler port 20 of a fuel tank 18 when refueling a motorcycle. The fuel lid opener circuit 10 includes a power supply 31 → an ignition switch 30 → a fuel opener solenoid 27 → an ignition switch
Electrical connection is made in the order of 30 → handle switch 33 → power supply 31. When the handle switch 33 is pressed, the fuel opener solenoid 27 is excited,
The lock lever 26 that locks the fuel lid 21 is rotated to the release position side via the fuel lid opener mechanism 22 shown in the drawing to release the lock mechanism 24, and the fuel lid 21 is opened.

The "OFF" position is a position when the motorcycle is not used, and the power supply 31 is not connected to any circuit.

According to this fuel lid opener circuit, a horn switch and a fuel opener solenoid, in which a handle switch 33 provided in the handle portion sounds a horn 32, are provided.
The fuel switch also serves as a fuel opener switch as an open switch for exciting the 27, and the ignition switch 30 is operated by operating the ignition switch 30.
The horn switch or the fuel opener switch can be switched and used by selectively interlocking each of the positions with the handle switch 33. Therefore, the conventional horn switch and fuel opener switch can be provided as one handle switch 33 on the handle portion.

〔The invention's effect〕

As described above, in the fuel lid opener circuit according to the present invention, since one handle switch serves as both the horn switch for sounding the horn and the fuel opener switch, the occupant releases his / her hand from the handle when refueling. The fuel lid can be opened with a simple operation of pressing the handle switch without any need. Further, by using the fuel opener switch also as the horn switch, the number of parts is reduced, and the mounting is simplified accordingly, so that the cost can be reduced and the aesthetic appearance can be improved.
