Description

locking mechanism

The present invention relates to a lock mechanism.

Conventionally, in a lock mechanism, a technique is known in which movement of an operating mechanism (operating mechanism) that opens and closes a tank cap is restricted by a regulating body that is operated by a solenoid (see Patent Document 1, for example).

JP 2017-196951 A

By the way, in the above-described conventional lock mechanism, if the solenoid and the restrictor are operated by an external force such as magnetic force, the lock will be released and the anti-theft property will be lowered. For this reason, there have been restrictions on the design of the solenoid and peripheral parts due to the need to adopt a structure that prevents deterioration of the anti-theft property. The constraints are, for example, the placement of the solenoid and the regulator, and the materials of the regulator and peripheral parts of the regulator.
SUMMARY OF THE INVENTION The present invention has been made in view of the circumstances described above, and is intended to improve anti-theft performance by suppressing unlocking due to an external force in a lock mechanism, and to increase the degree of freedom in designing solenoids and peripheral parts. Aim to improve.

This specification includes all the contents of Japanese Patent Application/Japanese Patent Application No. 2021-150562 filed on September 15, 2021.
The lock mechanism includes an operating mechanism, a first restricting body that moves to a regulating position that restricts the operation of the operating mechanism and a permitting position that allows the operation of the operating mechanism, and a solenoid that operates the first restricting body. In the locking mechanism, a second restricting body is provided that is movable in the moving direction of the first restricting body separately from the first restricting body, and the second restricting body moves the first restricting body to the allowable position. It is characterized in that the second restricting body can move to a second restricting position in which the operation of the operating mechanism is restricted by the second restricting body.

In the lock mechanism, it is possible to improve the anti-theft property by suppressing unlocking due to external force, and to improve the degree of freedom in designing the solenoid and peripheral parts.

That is, the fuel filler port lock member 45 can be extended and contracted in the longitudinal direction by sliding the pair of slide portions 45a.

When the cap member 41 is in the closed position as shown in FIG.
When the slide portion 45a is extended in the longitudinal direction, the top surface of the fuel filler port lock member 45 abuts the lower end 36a of the fuel filler port 36, thereby restricting the cap member 41 from swinging upward. In this state, the operation of the cap member 41 from the closed position to the open position is locked by the filler port locking member 45 .
The length of the filler port lock member 45 is shorter than the inner diameter of the filler port 36 when the slide portion 45a is contracted in the longitudinal direction as shown by the phantom lines in FIG. As a result, the sliding portion 45a does not come into contact with the lower end 36a of the filler port 36. As shown in FIG. In this state, the operation of the cap member 41 from the closed position to the open position is unlocked by the filler port lock member 45, and the cap member 41 can swing up and down.

When the manipulator 55 is pivoted upward from the state shown in FIG. 4, the manipulation of the manipulator 55 is transmitted to the filler cap lock member 45 via the interlocking member 51, and the slide portion 45a of the filler cap lock member 45 is It shrinks like the virtual line in FIG. Thereby, the locking of the cap member 41 is released. From this state, the cap member 41 is swung forward and downward to return to the closed position, and when the upper surface of the cap member 41 is pressed down, the sliding portion 45a is extended as indicated by the solid line in FIG. 41 is locked. The manipulator 55 is swung downward via the interlocking member 51 that interlocks with this movement.

The tank cap 40 has a lock mechanism 70 that locks the operation (operation) of the operating mechanism 50 .

FIG. 6 shows a state in which the operation of the operating mechanism 50 is restricted by the lock mechanism 70. As shown in FIG. FIG. 7 shows a state in which the restriction by the lock mechanism 70 is released and the operating mechanism 50 is operated.
The lock mechanism 70 operates the operating mechanism 50 , a first restricting body 71 capable of restricting the operation of the operating mechanism 50 , a second restricting body 72 capable of restricting the operation of the operating mechanism 50 , and the first restricting body 71 . and a restrictor holder 74 that holds the second restrictor 72 .

The operation interlocking member 56 and the operation biasing member 57 of the operation mechanism 50 and the lock mechanism 70 are arranged in the space portion 60 .
The operation interlocking member 56 moves in the vehicle width direction (horizontal direction) interlocking with the operation of the manipulator 55 . Although the moving direction D of the operation interlocking member 56 is the vehicle width direction, the moving direction D is not particularly limited, and may be, for example, the front-rear direction.
The operation interlocking member 56 is a shaft-shaped member extending in the movement direction D of the operation interlocking member 56, and extends in the vehicle width direction. The operation interlocking member 56 is held movably in the axial direction, for example, by a guide portion (not shown) provided on the side surface of the enclosing portion 42 a of the cap member 41 .

A distal end portion 56 a of the operation interlocking member 56 engages with an interlocking member engaging portion 58 a provided on the first protrusion 58 of the manipulator 55 .
A distal end portion 56a of the operation interlocking member 56 is formed in a tapered shape with a smaller diameter toward the distal end.
The interlocking member engaging portion 58a of the first projecting portion 58 is a hole with which the tip portion 56a engages. The inner surface of the interlocking member engaging portion 58a is tapered along the slope of the tip portion 56a.

The operation biasing member 57 biases the operation interlocking member 56 toward the first projecting portion 58 so that the distal end portion 56a engages the interlocking member engaging portion 58a. The operation biasing member 57 is, for example, a coil spring extending in the axial direction of the operation interlocking member 56 . One end of the operation biasing member 57 is connected to the end surface of the proximal end portion of the operation interlocking member 56, and the other end of the operation biasing member 57 is supported by the support portion 61 (FIG. 4).

The operation interlocking member 56 has an engaging portion 56b with which the first restricting body 71 engages. The engaging portion 56b is a hole penetrating the operation interlocking member 56 in the vertical direction. The engaging portion 56 b is provided between the tip portion 56 a and the operation biasing member 57 in the axial direction of the operation interlocking member 56 .

The first restricting body 71 and the solenoid 73 constitute a solenoid actuator 75 . The solenoid actuator 75 is driven by the controller 33 . The solenoid actuator 75 is fixed to the cap support member 42, for example.
The first restricting body 71 is a shaft-like member extending in the vertical direction.
The first restricting body 71 is housed in a cylindrical case 73 a of the solenoid 73 . The first restrictor 71 protrudes downward from the lower surface of the case 73a.

The first restricting body 71 is biased by a biasing member (not shown) included in the solenoid 73 so as to protrude downward as shown in FIG.
When the solenoid 73 is energized under the control of the control section 33, the first restricting body 71 moves upward as shown in FIG. 7 by the electromagnetic force of the solenoid 73 against the biasing force of the biasing member. The moving direction of the first restricting body 71 is the axial direction of the first restricting body 71 and the vertical direction. The moving direction of the first restricting body 71 is a direction orthogonal to the moving direction D of the operation interlocking member 56 .

The first restricting body 71 and the solenoid 73 are arranged above the operation interlocking member 56 and overlap the operation interlocking member 56 from above in plan view.
The first restricting body 71 moves between a restricting position that restricts the operation of the operating mechanism 50 and a permitting position that allows the operation of the operating mechanism 50 .
When the solenoid 73 is not energized, the first restricting body 71 is positioned at the restricting position as shown in FIG. At the restricting position, the first restricting body 71 engages with the engaging portion 56b of the operation interlocking member 56 from above to restrict the movement of the operation interlocking member 56 in the moving direction D. As shown in FIG.

When the solenoid 73 is energized, the first restricting body 71 is positioned at the allowable position, as shown in FIG. At the allowable position, the first restricting body 71 moves upward with respect to the restricting position and is disengaged from the engaging portion 56b. As a result, the operation interlocking member 56 can move in the movement direction D. As shown in FIG.

FIG. 8 is a cross-sectional view showing a state in which the second restrictor 72 has moved upward.
6 and 8, the second restricting body 72 and the restricting body holder 74 are arranged below the operation interlocking member 56 and overlap the operation interlocking member 56 from below in plan view. The second restricting body 72 and the restricting body holder 74 are provided so as to face the first restricting body 71 in the moving direction of the first restricting body 71 . The second restricting body 72 overlaps the first restricting body 71 and the solenoid 73 when viewed in the movement direction (vertical direction) of the first restricting body 71 .

The regulating body holder 74 is a tubular member having a vertically extending holding hole 74a. The lower end of the holding hole 74a is closed, and the upper end of the holding hole 74a opens upward. The regulator holder 74 is fixed to the cap support member 42, for example.
The second restrictor 72 is a shaft-like member that extends vertically. The second restrictor 72 is housed in the holding hole 74a and is vertically movable along the holding hole 74a.
The second restricting body 72 can be engaged with the engaging portion 56b of the operation interlocking member 56 from below. The second restrictor 72 is coaxial with the first restrictor 71 and positioned on the axis 71 a of the first restrictor 71 .
A solenoid 73 , a first restricting body 71 , an operation interlocking member 56 , and a second restricting body 72 are arranged in this order downward from the upper surface, which is the outer surface of the fuel tank 29 .

The second restrictor 72 moves between a second restriction position that restricts the operation of the operating mechanism 50 and a second allowable position that allows the operation of the operating mechanism 50 . The second restricting body 72 is movable separately from the first restricting body 71 in the movement direction of the first restricting body 71 .
The second restrictor 72 is located at the second allowable position in the state of FIG. At the second allowable position, the second restricting body 72 is positioned below the engaging portion 56b of the operation interlocking member 56 and is not engaged with the engaging portion 56b. In this state, the second restricting body 72 does not restrict movement of the operation interlocking member 56 . The second restrictor 72 is normally positioned at the second allowable position by the action of gravity.

The second restricting body 72 is located at the second restricting position in the state of FIG. At the second restricting position, the second restricting body 72 moves upward with respect to the second allowable position and engages with the engaging portion 56b of the operation interlocking member 56 from below. As a result, the movement of the operation interlocking member 56 in the movement direction D is restricted.
The limit position of the upward movement of the second restricting body 72 is the second restricting position. The movement of the second restricting body 72 above the second restricting position is restricted by, for example, contacting a portion of the restricting body holder 74 with a flange provided at the bottom of the second restricting body 72 .

The first restricting body 71 and the second restricting body 72 are ferromagnetic bodies, and are made of, for example, an iron-based material.
The solenoid actuator 75 and sensor 52 are electrical components.

Here, operations of the operating mechanism 50 and the locking mechanism 70 will be described.
3 to 5, when the manipulator 55 of the operating mechanism 50 is not operated, as shown in FIG. It is engaged with the portion 58a. In this state, the operation interlocking member 56 cannot move in the moving direction D because the first restricting body 71 is engaged with the engaging portion 56b and is in the restricting position.
That is, in the state shown in FIG. 6, the operation interlocking member 56 engaged with the interlocking member engaging portion 58a of the manipulator 55 cannot move in the moving direction D, so the manipulator 55 cannot move upward. Therefore, the operator cannot swing the manipulator 55 upward.

The control unit 33 receives an ID code for authentication from a smart key (not shown) carried by the operator via an antenna, and determines whether or not this ID code is a legitimate ID code. When the control unit 33 determines that the ID code is a valid ID code, the control unit 33 drives the solenoid 73 to move the first restricting body 71 to the allowable position as shown in FIG. As a result, the engagement of the first restricting body 71 with the engaging portion 56b is released, the operation interlocking member 56 becomes movable in the moving direction D, and the manipulator 55 can swing upward.

Next, the operator grips the overlapping portion 55b, for example, and swings the manipulator 55 upward about the swing shaft 55a as indicated by the phantom line in FIG. As a result, the operation of the manipulator 55 is transmitted to the filler opening locking member 45 via the interlocking member 51, and the locking of the cap member 41 by the filler opening locking member 45 is released. In this state, the operator can open the cap member 41 and refuel from the refueling port 36 .

When the manipulator 55 is pivoted upward, the interlocking member engaging portion 58a of the first projecting portion 58 also moves upward, as shown in FIG. Along with the upward movement of the interlocking member engaging portion 58a, the operation interlocking member 56 moves in the moving direction D as the front end portion 56a of the operation interlocking member 56 is pushed by the slope of the interlocking member engaging portion 58a. As a result, the engagement of the operation interlocking member 56 with the interlocking member engaging portion 58a is released.

For example, after refueling, the operator swings the cap member 41 downward to bring the cap member 41 to the closed position.
After that, the operator presses the upper surface of the cap member 41 . Then, the slide portion 45a of the filler port locking member 45 is extended as indicated by the solid line in FIG. 4 by a return mechanism (not shown). The operation of the filler port locking member 45 is transmitted to the manipulator 55 via the interlocking member 51, and the manipulator 55 is swung downward. The cap member 41 is locked by the filler port lock member 45 .

When the manipulator 55 swings downward, the interlocking member engaging portion 58a also moves downward, and as shown in FIG. 6, the operation interlocking member 56 engages with the interlocking member engaging portion 58a again.
When the sensor 52 detects that the cap member 41 is in the closed position, the controller 33 drives the solenoid 73 to move the first restricting body 71 to the restricting position, and moves the first restricting body 71 to the operation interlocking member 56 . Engage with the engaging portion 56b. As a result, the operation by the manipulator 55 is again restricted.

As shown in FIG. 2, a tank bag 76 capable of storing articles and the like can be attached to the upper surface of the fuel tank 29 .
The tank bag 76 is attached to the upper surface of the fuel tank 29 by the magnetic force of magnets 76 a provided on the lower surface of the tank bag 76 .

Referring to FIG. 8, when the magnet 76a is attached to the upper surface of the fuel tank 29, the magnetic force of the magnet 76a acts as an external magnetic force M on the lock mechanism 70 from the outside of the lock mechanism 70. As shown in FIG.
Even if the solenoid 73 is not energized, the first restricting body 71, which is a ferromagnetic body, can be pulled upward by an external magnetic force M and forced to move to the allowable position as shown in FIG. Conceivable.
In this case, the external magnetic force M also acts on the second restricting body 72, and the second restricting body 72 is pulled upward by the external magnetic force M to be positioned at the second restricting position as shown in FIG. As a result, the movement of the operation interlocking member 56 in the moving direction D is restricted, and the operation of the manipulator 55 is restricted.

That is, in the lock mechanism 70, even if the first restricting body 71 is forcibly positioned at the allowable position by the external magnetic force M, the second restricting body 72 operated by the external magnetic force M prevents the operator 55 from moving. operation can be regulated. Therefore, it is possible to prevent the operator 55 from being erroneously operated.
Further, even if a third person acts on the lock mechanism 70 not by the external magnetic force M of the tank bag 76 but by another external magnetic force M, the operation of the manipulator 55 can be restricted by the second restricting body 72 . Therefore, theft of the fuel in the fuel tank 29 can be suppressed.

The first restricting body 71 protrudes downward from the bottom surface of the solenoid 73 . Therefore, water and dust are prevented from entering the solenoid 73 along the first restricting body 71 .
The first restricting body 71 , the solenoid 73 , the second restricting body 72 , the operation interlocking member 56 , and the operation biasing member 57 are arranged in the space 60 within the cap housing recess 35 . Therefore, even if a special structure is not provided around the tank cap 40, the first restricting body 71, the solenoid 73, the second restricting body 72, the operation interlocking member 56, and the operation biasing member 57 are arranged around the fuel filler port 36. of fuel can be suppressed.

As described above, according to the embodiment to which the present invention is applied, the lock mechanism 70 has the operation mechanism 50, the restriction position for restricting the operation of the operation mechanism 50, and the allowable position for allowing the operation of the operation mechanism 50. A second restricting body 72 is provided which includes a moving first restricting body 71 and a solenoid 73 for operating the first restricting body 71 and is movable separately from the first restricting body 71 in the moving direction of the first restricting body 71. The second restricting body 72 is movable to the second restricting position where the second restricting body 72 restricts the operation of the operating mechanism 50 when the first restricting body 71 moves to the allowable position.
According to this configuration, the second restricting body 72 can move to the second restricting position to restrict the operation of the operating mechanism 50 when the first restricting body 71 is moved to the allowable position by an external force. Therefore, it is possible to suppress the release of the lock by the lock mechanism 70 due to an external force, thereby improving the anti-theft property.
In addition, since the above structure ensures anti-theft performance, the solenoid 73 and the first restrictor 71 can be arranged near the upper surface of the fuel tank 29 so that the axis 71a is oriented vertically. 71 has a high degree of freedom in arrangement. Further, the solenoid 73 and the first restricting body 71 do not need to be made of a material that is not easily affected by the external magnetic force M, which increases the degree of freedom in design. There is no need to provide a cover or the like as a dedicated peripheral part to cover the solenoid 73 and the first restricting body 71 so that they are not affected, and the degree of freedom in design is increased.

Further, the second restricting body 72 is moved to the second restricting position by the external magnetic force M when the first restricting body 71 is moved to the allowable position by the external magnetic force M acting from the outside of the lock mechanism 70 .
According to this configuration, the second restricting body 72 is moved to the second restricting position by the external magnetic force M when the first restricting body 71 is moved to the allowable position by the external magnetic force M. Therefore, unlocking of the lock mechanism 70 due to the external magnetic force M can be suppressed.
In addition, since the operation of the operating mechanism 50 can be regulated by the second regulating body 72, it is necessary to configure the first regulating body 71 with a special material that is not easily affected by the magnetic force, or to provide a protective member that blocks the external magnetic force M. , the structure can be simplified. In addition, since the first restricting body 71 and the solenoid 73 can be arranged even at a place affected by the external magnetic force M, the degree of freedom in arranging the first restricting body 71 and the solenoid 73 is improved. Therefore, for example, the wiring of the solenoid 73 can be easily routed.

Also, the second restricting body 72 overlaps the first restricting body 71 and the solenoid 73 when viewed in the moving direction of the first restricting body 71 .
According to this configuration, the external magnetic force M received by the first restricting body 71 and the solenoid 73 is likely to act on the second restricting body 72 as well. Therefore, the second restricting body 72 can be effectively moved to the second restricting position.

Furthermore, the first restricting body 71 and the second restricting body 72 move vertically during operation, and the first restricting body 71 moves upward from the restricting position to be positioned at the allowable position.

The lock mechanism 70 is provided on the tank cap 40 that closes the filler port 36 of the fuel tank 29 of the straddle-type vehicle 10 , and locks the opening and closing of the tank cap 40 .
According to this configuration, unlocking of the opening/closing of the tank cap 40 can be suppressed, and the anti-theft property of the fuel tank 29 can be improved.

A cap housing recess 35 is provided outside the filler port 36 on the outer surface of the fuel tank 29 , and the first restricting body 71 and the second restricting body 72 are arranged in the cap housing recess 35 .
According to this configuration, since the first restricting body 71 and the second restricting body 72 are arranged in the cap housing recess 35 , the first restricting body 71 and the second restricting body 72 are not exposed to the fuel in the fuel tank 29 . can be suppressed.

A solenoid 73, a first restricting body 71, and a second restricting body 72 are arranged in this order from the outer surface side of the fuel tank 29 downward. By moving downward from the allowable position by force, it is positioned at the restricted position.
According to this configuration, since the first restricting body 71 moves downward and is positioned at the restricting position, gravity is used in addition to the biasing force of the biasing member to move the first restricting body 71 to the restricting position. can be done. In addition, since the biasing force of the biasing member can be reduced, the force required to move the solenoid 73 from the restricted position to the allowable position can be reduced, and power saving and miniaturization of the solenoid 73 can be achieved.

Furthermore, in the restricted position, the first restricting body 71 engages with the engaging portion 56b provided in the operating mechanism 50, and the engaging portion 56b penetrates the operating mechanism 50 in the movement direction of the first restricting body 71. The second restricting body 72, which is a hole, engages with the engaging portion 56b at the second restricting position.
According to this configuration, the first restricting body 71 and the second restricting body 72 restrict the operation of the operating mechanism 50 by engaging with the engaging portion 56 b which is the same hole provided in the operating mechanism 50 . Therefore, the structure can be simplified.

In addition, the above-described embodiment shows one mode to which the present invention is applied, and the present invention is not limited to the above-described embodiment.
