[Industrial applications]

 The present invention relates to a solenoid for a fuel lid opener which is used, for example, to automatically open a fuel lid of an automobile from a locked state.

[0002]

[Prior Art]

 FIG. 3 illustrates a fuel lid opener solenoid used to automatically open a fuel lid of an automobile from a locked state.

The illustrated fuel lid opener solenoid 50 is fixed by inserting the tip side of the solenoid case 50 a into the opener fixing hole 81 a provided in the fuel filler portion 81 of the vehicle body 80 and then screwing the nut 50 b. There is.

Further, a fuel lid locking portion 51 projects from the solenoid case 50a into the fuel filler portion 81, and a striker 81b1 provided on the fuel lid panel 81b is locked to the fuel lid locking portion 51, whereby the fuel is locked. The lid panel 81b is locked.

In the solenoid case 50a, a coil portion 53 is wound around a bobbin 52 having a plunger insertion hole 52a, and a cylindrical frame 54 is attached to the outer peripheral side of the bobbin 52. A plunger 55 having an axial shape is inserted into the insertion hole 52a.

Further, the fuel lid locking portion 51 is connected to the tip end side of the plunger 55, and the shaft protruding from the fuel filler portion 81 toward the trunk 82 side is attached to the base end side of the plunger 55. The base end side of 56 is connected, and the shaft 56, the fuel lid locking portion 51, and the plunger 55 are integrally urged toward the fuel filler portion 81 by a return spring (not shown) attached to the plunger 55. When the coil portion 53 is excited by supplying an exciting power source from the external wiring 60 connected to the coil portion 53, a magnetic force passing through the coil portion 53 → frame 54 → plunger 55 is generated. The output is moved to the right side in FIG.

Further, one end side of a metal wire 57 is tied to the tip side of the shaft 56, and the tip side of the wire 57 passes through an insertion hole 82a1 provided in the trunk inner panel 82a and inside the trunk 82. It hangs and is attached to a manual operating plate 58.

In the fuel lid opener 50 having such a structure, the fuel lid panel 81b is closed and in a locked state in a state where the fuel lid locking portion 51 is locked to the striker 81b1 of the fuel lid panel 81b.

Therefore, when a coil opener 53 is excited by supplying an excitation power from an external wiring 56 by turning on a lid opener switch (not shown), the plunger 55 resists the elastic repulsive force of the return spring. Then, the output is moved to the right side in FIG. 3, so that the fuel lid locking portion 51 is disengaged from the striker 81b1.

When the fuel lid locking portion 51 is disengaged from the striker 81b1, the fuel lid panel 81b is unlocked and opened by a return spring (not shown), and the coil portion 53 is demagnetized by turning off the lid opener switch. Then, the plunger 55 returns to the left side in FIG. 3 due to the elastic repulsive force of the return spring.

When the fuel lid panel 81b is opened and the fuel lid panel 81b is pressed from the upper side in the figure, the striker 81b1 of the fuel lid panel 81b abuts the fuel lid locking portion 51, and the fuel lid locking portion 51 is locked. Since the plunger 55 is pushed and moved to the output moving side against the elastic repulsive force of the return spring, the striker 81b1 is locked to the fuel lid locking part 51 after passing over the fuel lid locking part 51. Then, the fuel lid panel 81b is locked.

Further, when the striker 81b1 of the fuel lid panel 81b is locked by the fuel lid locking portion 51, the excitation power cannot be supplied to the coil portion 53 due to battery exhaustion or the like. In this case, the trunk lid (not shown) of the trunk 82 is opened by a key, and the manually operating plate 58 of the wire 57 hanging in the trunk 82 is pulled by hand to force the shaft 56 to the trunk 82 side. When it is moved to, the plunger 55 also moves to the output moving side against the elastic repulsive force of the return spring, so that the fuel lid locking part 51 is disengaged from the striker 81b1, and the fuel lid panel 81b is unlocked. , An emergency that opens the fuel lid panel 81b It is used as a lid opening means for sea.

[0013]

[Conventional problems]

 However, in the conventional fuel lid opener solenoid 50 described above, the wire 57, which is the opening means for emergency, and the manual operation plate 58 hang down in the trunk 82, so the inside of the trunk 82 is complicated. It is hard to say that it doesn't look like, and there is a problem that it may give the user the impression that it will reduce the luxury of the vehicle. In addition, since the manual operation plate 58 is pulled by hand from inside the trunk 82 via the wire 57 during an emergency, the shaft 56 is forcibly moved to the trunk 82 side. It is hard to say that the solenoid case 50a accommodating the plunger 55 is likely to be damaged if the force is large, and there is a problem that if the solenoid case 50a is damaged, electrical automatic opening may also be possible.

[0014]

[Problems to be solved by the device]

 The problem to be solved is that if the lid opening means for emergency is configured by the wire pulled out into the trunk or the plate for manual operation, the inside of the trunk may look complicated and malfunction may occur.

[0015]

[Means for Solving the Problems]

 The solenoid for the fuel lid opener according to the present invention is provided with a rod extending from the proximal end side of the plunger in the plunger in order to prevent it from appearing complicated in the mounted state and prevent malfunction. In addition, it is characterized by being provided with a hook for manual operation, and realizes the purpose of performing a reliable operation that does not look complicated in a mounted state.

[0016]

[Action]

 In the fuel lid opener solenoid according to the present invention, the plunger is operated to the output moving side by moving the manual operation hook provided on the rod with a finger, and therefore the wire pulled out into the trunk or the manual operation plate is used for the emergency operation. There is no protruding part in the trunk in the mounted state, compared to the lid opening means for use, so the inside of the trunk does not look complicated and the plunger can be moved by finger operation. , Since it does not apply a large force to the plunger as when it is pulled by hand, it is less likely to damage the component parts.

【Example】

 1 and 2 show an embodiment of a solenoid for a fuel lid opener according to the present invention.

The illustrated fuel lid opener solenoid 1 is provided with a solenoid coil 3 in which a coil portion 2 b is wound around a bobbin 2 having a plunger insertion hole 2 a, and a magnetic path is formed on the outer peripheral side of the solenoid coil 3. A cylindrical frame 4 made of a magnetic material and having a cylindrical shape is attached.

Further, a base end side of a non-magnetic top 7 is fitted to a top end of the frame 4 in FIG. 1 which is an upper side, via a disk-shaped base 5, and the top end is made of a non-magnetic material. A screw portion 7a for fixing the body side and a round hole 7b are provided on the tip side of 7.

At the base end side, which is the lower side in FIG. 1 of the frame 4, a disk-shaped base 8 made of a magnetic material is attached in contact with the bottom of the bobbin 2. A bottom portion 9 made of a magnetic material and having a substantially conical shape is fixed to the inner peripheral side of 8 while being inserted into the plunger insertion hole 2a of the bobbin 2, and the center of the bottom portion 9 of the plunger insertion hole 2a. A rod insertion hole 9a is provided along the opening direction.

Further, in the plunger insertion hole 2a of the bobbin 2, a substantially cylindrical cylinder 10 made of a magnetic material is provided with a recess 10a1 which is approximate to the conical shape of the bottom 9 near the base end 10a. Are housed so as to be movable upward and downward in FIG. 1, and a return spring 11 which is a torsion coil spring is engaged with the base end 10a and the bottom 9 of the plunger 10, respectively. Plunger 10 is biased upward in FIG. 1 by the elastic repulsive force of 11.

A rod locking hole 10b corresponding to the rod insertion hole 9a of the bottom 9 is provided at the center of the plunger 10, and the rod insertion hole 9a of the bottom 9 is inserted into the rod locking hole 10b. The inserted shaft-shaped non-magnetic rod 12 is fixed near the tip, and the tip 12a side and the base end 12b side of the rod 12 project from the tip 10c and the base end 10a of the plunger 10, respectively.

Further, as is apparent from FIG. 2, on the tip side of the rod 12 protruding from the tip 10c of the plunger 10, a protrusion 13a formed in a trapezoidal shape is provided on the tip side and made of a non-magnetic material. The base end side of the fuel lid locking portion 13 is fixed, and the fuel lid locking portion 13 projects from the top 7 in a state of being inserted into the round hole 7b of the top 7 via the O (O) ring 14.

Then, on the base end 12b side of the rod 12 protruding from the base end 10a of the plunger 10, as is apparent from FIG. 2, a manual operation in which the rod 12 is bent at a substantially right angle downward in FIG. A hook 12b1 for use is provided.

On the other hand, on the base end side of the frame 4, holders 14 and 15 having rod insertion holes 14a and 15a in the center are assembled, and the coil portion 2b of the bobbin 2 is attached to the holder 14 on one side. External connection terminals 16 and 17 connected to the above are provided, and a bracket 15a for fixing to the vehicle body side is provided outside the holder 15 on the other side.

When the coil portion 2b is excited by supplying excitation power, the coil portion 2b passes through the coil portion 2b → frame 4 → base 5 → plunger 10 → bottom 9 → base 8 → frame 4 → coil portion 2b. Since a magnetic force is generated, the plunger 10 is attracted to the bottom 9 side, and the plunger 10 moves against the elastic repulsive force of the return spring 11 at the stroke st from position A to position B shown in FIG. Therefore, the fuel lid locking portion 13 and the rod 12 output-move integrally with the plunger 10, so that the projection 13a of the fuel lid locking portion 13 moves from the A1 position to the B1 position shown in FIG. Stroke and the hook 12b1 of the rod 12 is the same as the above stroke from the A2 position to the B2 position shown in FIG. Make a stroke.

When the coil unit 2b is demagnetized by stopping the supply of the excitation power to the coil unit 2b, the elastic restoring force of the return spring 11 of the plunger 10 changes the position from the B position to the A position shown in FIG. The stroke st returns to return.

As shown in FIG. 2, the fuel lid opener solenoid 1 having such a structure inserts the screw portion 7 a of the top 7 from the trunk 82 side into the opener fixing hole 81 a provided in the fuel filler portion 81 of the vehicle 80. Then, the nut 18 is screwed in, and the bracket 15a is attached to the bracket receiver 81c provided in the fuel filler portion 81, whereby the nut is fixed to the vehicle body 80, and the external wiring 83 is attached to the external connection terminals 16 and 17. Connecting.

With the fuel lid opener solenoid 1 fixed to the fuel filler portion 81, the rod 12 projects toward the trunk 82 side, and the hook 12b1 of the rod 12 is located on the side of the trunk inner panel 82a. Is located in the vicinity of the small hole 82a2 provided in the trunk lid 82 and does not project into the trunk 82, and the projection 13a of the fuel lid locking portion 13 is locked to the striker 81b1 of the fuel lid panel 81b. In this state, the fuel lid panel 81b is closed and locked.

Therefore, a lid opener switch (not shown) is turned on to supply excitation power from the external wiring 83 to excite the coil portion 2b, thereby resisting the elastic repulsive force of the plunger 10 in the return spring 11. When the output is moved by the stroke st from the A position to the B position shown in FIG. 1, the fuel lid locking portion 13 also strokes integrally with the plunger 10 from the A1 position to the B1 position shown in FIG. The protrusion 13a of the fuel lid locking portion 13 is disengaged from the striker 81b1 of the fuel lid panel 81b.

When the projection 13a of the fuel lid locking portion 13 is released from the striker 81b1, the fuel lid panel 81b is unlocked and opened by a return spring (not shown), and the coil opening 2b is demagnetized by turning off the lid opener switch. Then, the plunger 10 is moved back from the position B to the position A shown in FIG. 1 by the elastic restoring force of the return spring 11.

Then, when the fuel lid panel 81b is pressed from the upper side in FIG. 2 with the fuel lid panel 81b being opened, the striker 81b1 of the fuel lid panel 81b comes into contact with the projection 13a of the fuel lid locking portion 13, so that the fuel lid panel 81b is pressed. Since the plunger 10 is pushed and moved toward the output moving side against the elastic repulsive force of the return spring 11 via the locking portion 13, after the striker 81b 1 crosses the projection 13a of the fuel lid locking portion 13, the fuel lid engagement is performed. The fuel lid panel 81b is locked by being locked to the protrusion 13a of the stopper 13.

Further, when the striker 81b1 of the fuel lid panel 81b is locked by the protrusion 13a of the fuel lid locking portion 13, the lid opener switch is used to excite the coil portion 2b due to battery exhaustion or the like. When the power cannot be supplied, the trunk lid (not shown) of the trunk 82 is opened by the key, and a finger is inserted into the small hole 82a2 of the trunk inner panel 82a, so that the rod 12 located near the small hole 82a2 is inserted. The hook 12b1 is moved from the A2 position, which is the output movement direction of the plunger 10, toward the B2 position.

At this time, since the exciting power is not supplied to the coil portion 3, the plunger 10 is in the A position, and the hook 12b1 of the rod 12 is also in the A2 position. Corresponding to the movement of the hook 12b1 from the A2 position to the B2 position, the plunger 10 also moves from the A position to the B position against the elastic repulsive force of the return spring 11, and the projection 13a of the fuel lid locking portion 13 is also pushed. It moves from the A1 position to the B1 position corresponding to the runger 10.

By moving the protrusion 13a of the fuel lid locking portion 13 from the A1 position to the B1 position, the protrusion 13a of the fuel lid locking portion 13 is disengaged from the striker 81b 1. Therefore, the fuel lid panel 81b is unlocked and the fuel lid panel 81b is unlocked. The panel 81b is brought into an open state, which provides an emergency opening means.

[0036]

As described above, since the fuel lid opener solenoid according to the present invention has the above-mentioned configuration, the plunger is operated to the output moving side by moving the manual operation hook with a finger. Therefore, in comparison with the structure that the lid opening means for emergency is configured by the wire pulled out into the trunk or the plate for manual operation, there are no protruding parts in the trunk when mounted on the vehicle. Since the inside of the trunk does not look complicated and the plunger is moved by finger operation, a large force like pulling it by hand does not act on the plunger, which causes malfunction of the component parts. It is highly unlikely that this will result in a reliable operation.
