A locking device for a vehicle according to the present embodiment is applied to a fuel tank cap locking device for locking or unlocking the opening and closing of a cap for closing a fuel filler port leading to a fuel tank in a large motorcycle. As shown in FIGS. 1 to 6, the fuel tank cap locking device includes a cap 1, an operation knob 2 (operating means), a locking means 3, a solenoid 5, a slider 6, and a detection switch 8. It is configured with In addition, the above components are accommodated in a main body R fixed to a fuel tank T having a filler port Ta. Further, as shown in FIGS. 1 to 3, an annular cover portion H is fixed to the upper portion of the main body R with a plurality of bolts.

The cap 1 moves between a closed position (see FIG. 2(a)) in which the fuel filler opening Ta leading to the fuel tank of the vehicle is closed and an open position (see FIG. 2(b)) in which the filler filler opening is opened. Ta can be opened and closed, and is composed of an upper cap portion 1a and a lower cap portion 1b. In this embodiment, when an operator such as a driver picks up the operation knob 2 and pulls it upward, the cap 1 swings around the swing axis La and moves from the closed position to the open position. The fuel filler port Ta can be exposed to the outside.

As shown in FIG. 2, the upper cap portion 1a is formed with a swing shaft La at a predetermined position for swinging the cap 1 between a closed position and an open position. Further, the upper cap portion 1a holds an operation knob 2 (operation means) at its upper portion so as to be swingable. The lower cap portion 1b is provided with a sealing material S for sealing the filler opening Ta when the cap 1 is in the closed position, and the locking means 3 is positioned between the locking position and the allowable position as shown in FIGS. It is configured to be accommodated in a state that can be moved between.

As shown in FIGS. 2 and 4 to 6, the operating knob 2 (operating means) is integrally formed with a swing shaft Lb, and protrusions 2a are formed at both ends of the swing shaft Lb. It is attached to a recess formed in the upper surface of the cap 1 (upper cap portion 1a). When the operator pulls up the operation knob 2 and operates it, the operation knob 2 can be operated to swing about the swing axis Lb.

The locking means 3 is movable in conjunction with the operation of the operation knob 2, and has a locking position (see FIG. 4) in which the cap 1 blocks the filler opening Ta and a state in which the locking is released. As shown in FIGS. 4 and 5, the urging force of the coil spring 4 moves the cap 1 from the allowable position to the locking position. is biased toward

More specifically, the locking means 3 according to this embodiment can slide substantially linearly in the working space (see FIG. 6) inside the lower cap portion 1b. As shown in FIG. 4, the engaging portion 3a at the tip is engaged with the engaged portion Ha formed in the cover portion H to restrict the movement of the cap 1 from the closed position to the open position, and the operation knob 2 is operated to the allowable position, as shown in FIG. is configured to

Furthermore, in this embodiment, the operation of the locking means 3 from the locking position to the permitting position is locked, or the lock is released to permit the movement of the locking means 3 from the locking position to the permitting position. It is equipped with a solenoid 5 to obtain. Specifically, the solenoid 5 according to the present embodiment is composed of an actuator capable of displacing the plunger 5a when energized. When moving to the position, it is possible to move between an interference position where it interferes with and locks a predetermined portion of the locking means 3 and a non-interference position where it unlocks without interfering with the interfered portion.

The plunger 5a can be displaced between a protruded state and a contracted state by energization. A spring (not shown) constantly urges from the contracted state (non-interference position) to the projected state (interference position). That is, when the plunger 5a is not energized, it is protruded (interference position) by the biasing force of the internal spring and locks the locking means 3. When the plunger 5a is energized, it resists the biasing force of the internal spring. is brought into a contracted state (non-interference position) and the lock of the locking means 3 is released.

As shown in FIG. 7, the solenoid 5 according to this embodiment is housed in a unit fixed at a predetermined position within the main body R, and the plunger 5a protrudes outside the unit. This unit has a mounting case in which the slider 6 and the detection switch 8 are mounted, and the solenoid 5, the slider 6 and the detection switch 8 are integrated parts.

Furthermore, in the present embodiment, the slider 6 interlocking with the locking means 3 and the detection switch 8 capable of detecting the movement of the slider 6 are provided, and the condition is that the detection switch 8 detects the movement of the slider 6. , so that the solenoid 5 can be unlocked. Specifically, as shown in FIG. 8, the slider 6 and the detection switch 8 are attached to a mounting case that constitutes the unit, and the protruding portion 6a of the slider 6 protrudes to the outside of the unit. . In addition, the symbol f in the drawing indicates a sealing material for waterproofing.

The slider 6 is biased to the right in FIG. there is Further, the slider 6 has a pressing surface 6b capable of pressing the operating portion 8a of the detection switch 8 at a location different from the projecting portion 6a. It is configured to electrically turn on the detection switch 8 by pressing, or electrically turn off the detection switch 8 by separating the pressing surface 6b from the operating portion 8a.

When the locking means 3 is at the locking position, the pressing surface 6b of the slider 6 is separated from the operating portion 8a, and the detection switch 8 is electrically off. When the operation knob 2 is started to operate and the locking means 3 begins to move from the locking position toward the allowable position, the slider 6 follows the locking means 3 by the biasing force of the coil spring 7 and moves in the same direction. , the pressing surface 6b presses the operating portion 8a, and the detection switch 8 is electrically turned on. Thus, when the detection switch 8 detects the movement of the slider 6 and turns it on electrically, the solenoid 5 is energized and the lock is released. 3 will be moved to the allowable position.

In addition, as shown in FIG. 9, the vehicle to which this embodiment is applied has transmission means 9 which can be carried by the driver and which transmits an ID code unique to the vehicle on radio waves, and a transmitting/receiving means 10 (receiving means) capable of transmitting a search signal from the transmitting means 9 and receiving an ID code from the transmitting means 9; and a judgment means 11 for judging whether or not the ID code is a valid ID code. It is designed to allow

Further, the determination means 11 according to the present embodiment is electrically connected to the detection switch 8, so that the determination means 11 is determined to have received a valid ID code, and the detection switch 8 confirms that the locking means 3 is On the condition that the movement is detected, the plunger 5a of the solenoid 5 is contracted to the non-interference position to unlock. That is, when the determination means 11 determines that a valid ID code has been received, the start of movement of the locking means 3 is detected by the detection switch 8, thereby moving the plunger 5a of the solenoid 5 from the projecting state (interference position). The locking means is unlocked as a contracted state (non-interfering position), allowing the locking means 3 to move from the locking position to the allowable position, and determining that the determination means 11 has received a valid ID code. If not, even if the detection switch 8 detects the start of movement of the locking means 3, the plunger 5a of the solenoid 5 is maintained in the projecting state (interference position) so that the unlocking operation by the locking means is not performed. there is

(ie, operation of the operation means in the case), the solenoids 20 to 22 corresponding to the detected detection switches 23 to 25 are energized to unlock each case.

Here, the control unit 13 according to the present embodiment can control the energization timing by repeatedly turning on and off the solenoids 18, 20 to 22 at a predetermined frequency as described above, and the frequency depends on the output time. For example, the frequency can be arbitrarily set to approximate the frequency used in the musical scale.

According to this embodiment, the plunger is movable between a lock position for locking the lock parts (tank cap, seat lock, and case) and a release position for unlocking the lock, and the plunger is locked by energization. The solenoids 5, 18, 20-22 that can be moved from the position to the release position, and the solenoids 5, 18, 20-22 are repeatedly turned on and off at a predetermined frequency to control the energization timing, and the frequency is the output time. Since the controller 13 is arbitrarily set according to the conditions, the generation of unpleasant noise can be avoided while suppressing the heat generation of the solenoids 5, 18, 20-22.
