Description

[Technical Field]

[0001] The present invention relates to a locking mechanism. [Background technology]

[0002] BACKGROUND ART Conventionally, in a locking mechanism, a technique is known in which the movement of an operating mechanism (operating mechanism) that opens and closes a tank cap is restricted by a restricting body operated by a solenoid (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-196951 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional locking mechanism described above, if the solenoid and the restrictor are operated by an external force such as a magnetic force, the lock is released, resulting in a decrease in theft prevention capability. Therefore, the need to adopt a structure that prevents a decrease in theft prevention capability places design constraints on the solenoid and peripheral components. These constraints include, for example, the placement of the solenoid and the restrictor, and the materials of the restrictor and the peripheral components of the restrictor. The present invention has been made in consideration of the above-mentioned circumstances, and aims to improve theft prevention in a locking mechanism by preventing the lock from being released by external force, and to increase the design freedom of the solenoid and peripheral parts, etc. [Means for solving the problem]

[0005] The locking mechanism comprises an operating mechanism, a first regulating body that moves to a regulating position that regulates the operation of the operating mechanism and to an allowable position that allows the operation of the operating mechanism, and a solenoid that operates the first regulating body, and is characterized in that a second regulating body is provided that is movable separately from the first regulating body in the movement direction of the first regulating body, and when the first regulating body moves to the allowable position, the second regulating body can be moved by the second regulating body to a second regulating position that regulates the operation of the operating mechanism. [Effects of the Invention]

[0006] In the locking mechanism, the unlocking caused by an external force is prevented, improving theft prevention, and the degree of freedom in designing the solenoid and peripheral components is improved. [Brief explanation of the drawings]

[0016] FIG. 2 is a plan view of the saddle-ride type vehicle 10 (vehicle) seen from above. 1 and 2, the saddle-ride type vehicle 10 is provided with a body cover that covers the body constituted by the body frame 11 etc., which includes a front cover 31 that covers the head pipe 18 from the front, and a pair of left and right side covers 32 that cover the front end of the body frame 11 from the outside in the vehicle width direction.

[0017] The fuel tank 29 is disposed between the head pipe 18 and the seat 17 in the vehicle front-rear direction. The fuel tank 29 is disposed above the left and right main frames 19a and is supported by the main frames 19a. A tank cap 40 that can be opened and closed to cover the fuel tank 29 is provided on the upper surface of the front part of the fuel tank 29. The tank cap 40 is disposed in the center in the vehicle width direction.

[0018] The control unit 33, which electronically controls each part of the saddle-ride type vehicle 10, such as the power unit 12, is disposed below the rear part of the fuel tank 29. The control unit 33 is disposed behind the cylinder unit 24 and above the rear part of the crankcase 23, between the rear parts of the left and right main frames 19a. A battery 34 that supplies power to each part of the saddle-ride type vehicle 10 is disposed below the seat 17.

[0019] FIG. 3 is a plan view of the portion of the fuel tank 29 where the tank cap 40 is provided, as viewed from above. The tank cap 40 includes a cap member 41 that closes the fuel tank 29 in an openable and closable manner, and a cap support member 42 that supports the cap member 41 in an openable and closable manner. The cap member 41 has a disk shape in a plan view. In a plan view, the cap support member is an annular member that surrounds the cap member 41. The cap member 41 is attached to the fuel tank 29 via the cap support member .

[0020] Fig. 4 is a view of the tank cap 40 of Fig. 3 as seen from the front side of the vehicle. Fig. 5 is a side view of the tank cap 40 of Fig. 3 as seen from the left side. Figs. 4 and 5 show a cross section of a portion of the fuel tank 29. 3 to 5, a cap receiving recess 35 (recess) for receiving a tank cap 40, and a fuel filler opening 36 are provided on the upper surface of the front portion of the fuel tank 29. The cap accommodating recess 35 is a recess formed by a portion of the upper surface of the fuel tank 29 being recessed downward. In a plan view, the cap accommodating recess 35 is a substantially circular recess that follows the outer periphery of the cap support member 42. The cap accommodating recess 35 is located on the upper surface of the fuel tank 29, which is the outer surface of the fuel tank 29, outside the fuel filler opening 36 in a plan view. When the tank cap 40 is stored in the cap storage recess 35, the upper surface 40a of the tank cap 40 and the upper surface of the fuel tank 29 become substantially flush with each other.

[0021] The cap storage recess 35 includes a cylindrical peripheral wall portion 35a that surrounds the tank cap 40, and a bottom wall portion 35b that receives the tank cap 40 from below. The peripheral wall portion 35a extends upward from the peripheral edge of the bottom wall portion 35b.

[0022] The fuel filler opening 36 is disposed in the center of the bottom wall portion 35b of the cap storage recess 35 in a plan view. The fuel filler opening 36 is a cylindrical member that passes through the bottom wall portion 35b in the vertical direction. The fuel filler opening 36 extends downward inside the fuel tank 29 relative to the bottom wall portion 35b. The fuel filler opening 36 also extends upward relative to the bottom wall portion 35b.

[0023] The cap support member 42 is attached from above to the bottom wall portion 35b of the cap storage recess 35, and is surrounded from the periphery by the peripheral wall portion 35a. The cap support member 42 includes an annular surrounding portion 42a that surrounds the outer periphery of the cap member 41, and an annular flange portion 42b that extends radially outward from the upper end of the surrounding portion 42a. The cap support member 42 also includes a front mounting portion 42c extending downward from the front end portion of the cap support member 42, and a rear mounting portion 42d extending downward from the rear end portion of the cap support member 42. The rear mounting portion 42d is longer in the vehicle width direction than the front mounting portion 42c. The front mounting portion 42c and the rear mounting portion 42d of the cap support member 42 abut against the bottom wall portion 35b from above, and the cap support member 42 is fastened to the bottom wall portion 35b by a plurality of fasteners 43 that are inserted into the cap support member 42 from above.

[0024] The cap member 41 is fitted onto the inner periphery of the surrounding portion 42 a of the cap support member 42 . A cap swing shaft 41a is provided at the rear end of the cap member 41, connecting the cap member 41 to the cap support member 42 so that the cap member 41 can swing freely. The cap pivot shaft 41a is a shaft that extends in the vehicle width direction (left and right direction) in the plan view of Fig. 3. The cap pivot shaft 41a is connected to the rear end of the cap support member 42 at the center in the vehicle width direction. The cap member 41 swings up and down around the cap swing shaft 41a. That is, the cap member 41 swings up and down around the rear end of the cap member 41.

[0025] When the cap member 41 is in the closed position as shown in FIG. 4, it abuts against the upper edge of the fuel filler opening 36 to close the opening of the fuel filler opening 36. The cap member 41 is positioned in the open position when it swings upward as shown by the phantom lines in Figure 1. When the cap member 41 is in the open position, the fuel filler opening 36 is exposed upward, making it possible to fill the fuel tank 29 through the fuel filler opening 36.

[0026] The tank cap 40 includes a fuel filler neck locking member 45 that locks and unlocks the movement of the cap member 41 from the closed position to the open position, an operating mechanism 50 that operates the fuel filler neck locking member 45 by swinging, an interlocking member 51 that transmits the operation of the operating mechanism 50 to the fuel filler neck locking member 45, and a sensor 52 that detects the operating state of the operating mechanism 50.

[0027] 3 to 5, the operating mechanism 50 includes an operator 55 arranged on the upper surface of the cap member 41, an operation interlocking member 56 connected to the operator 55 and moving in conjunction with the operation of the operator 55, and an operation biasing member 57 that biases the operation interlocking member 56. The operating element 55 is a plate-shaped operating lever that extends longitudinally in the vehicle front-rear direction along the upper surface of the cap member 41, and is located in the center in the vehicle width direction. The operating element 55 is located on a step 40b (FIG. 4) that is recessed in the upper surface 40a of the tank cap 40 by approximately the same amount as the plate thickness of the operating element 55.

[0028] A swing shaft 55a extending in the vehicle width direction is provided at the rear end, which is one end of the operator 55. The operator 55 is connected to the rear part of the upper surface of the cap member 41 via the swing shaft 55a. The operator 55 can swing up and down around the swing shaft 55a.

[0029] An overlapping portion 55b is provided at the front end portion, which is the other end portion of the operator 55, and overlaps the front end portion of the cap support member 42 from above. The overlapping portion 55b covers the cap support member 42 from above. The fastener 43 arranged at the front end portion of the cap support member 42 is covered from above by the overlapping portion 55b. The operator 55 includes a first protrusion 58 that protrudes downward from the lower surface of the overlapping portion 55b, and a second protrusion 59 that protrudes downward from the lower surface of the overlapping portion 55b. The first protrusion 58 is provided at one end in the width direction of the overlapping portion 55b, and the second protrusion 59 is provided at the other end in the width direction of the overlapping portion 55b.

[0030] The first protrusion 58 and the second protrusion 59 pass through holes provided in the flange portion 42b of the cap support member 42 and protrude inward of the cap support member 42. 3 to 5, below the cap support member 42, a space 60 is provided which is covered by the flange portion 42b of the cap support member 42, the surrounding portion 42a, the peripheral wall portion 35a of the cap storage recess 35, and the bottom wall portion 35b. The first protrusion 58 and the second protrusion 59 protrude into the space 60 .

[0031] The sensor 52 is disposed in the space 60 below the cap support member 42 . Sensor 52 detects second protrusion 59 of operator 55. Control unit 33 determines whether operator 55 is being operated based on the input from sensor 52. Sensor 52 is, for example, a contact sensor. When the operation element 55 is not operated as shown in FIG. 4, the sensor 52 detects the second protrusion 59 by the detector 52a at the tip. When the operating element 55 is operated and swung upward, the detector 52 a does not come into contact with the second protrusion 59 , and the sensor 52 does not detect the second protrusion 59 .

[0032] The fuel filler neck locking member 45 is disposed directly below the center of the cap member 41 in a plan view. The cap member 41 has a lock member support portion 41b (FIG. 4) that extends downward from the underside of the cap member 41. The fuel filler neck lock member 45 is fixed to the lock member support portion 41b and swings integrally with the cap member 41. The lock member support portion 41b passes through the fuel filler neck 36. The lock member support portion 41b is not shown in FIG. The fuel filler neck locking member 45 is shaped like a block that is long in the vehicle width direction. The fuel filler neck locking member 45 is provided with slide portions 45a at both longitudinal ends that are slidable in the longitudinal direction of the fuel filler neck locking member 45. In other words, the fuel filler neck locking member 45 is able to expand and contract in the longitudinal direction by sliding the pair of slide portions 45a.

[0033] When the cap member 41 is in the closed position as shown in FIG. 4, the fuel filler neck lock member 45 is located below the lower end a of the fuel filler neck . When the sliding portion 45a of the fuel filler neck locking member 45 is extended in the longitudinal direction, the upper surface of the sliding portion 45a abuts against the lower end 36a of the fuel filler neck 36, restricting the upward swing of the cap member 41. In this state, the movement of the cap member 41 from the closed position to the open position is locked by the fuel filler neck locking member 45. 4, when the sliding portion 45a is contracted in the longitudinal direction, the length of the fuel filler neck locking member 45 becomes shorter than the inner diameter of the fuel filler neck 36. As a result, the sliding portion 45a does not abut against the lower end 36a of the fuel filler neck 36. In this state, the movement of the cap member 41 from the closed position to the open position is unlocked by the fuel filler neck locking member 45, and the cap member 41 can swing up and down.

[0034] The operating element 55 is connected to the fuel filler neck locking member 45 via an interlocking member 51 . Interlocking member 51 extends downward from the underside of operating element 55 and is connected to the upper surface of fuel filler neck locking member 45. Interlocking member 51 includes, for example, a first interlocking member that moves up and down in conjunction with the up and down swing of operating element 55, and a second interlocking member that converts the up and down movement of this first interlocking member into rotational movement and transmits it to fuel filler neck locking member 45.

[0035] When the operating element 55 is operated to swing upward from the state shown in FIG. 4, the operation of the operating element 55 is transmitted to the fuel filler neck locking member 45 via the interlocking member 51, and the sliding portion 45a of the fuel filler neck locking member 45 contracts as shown by the imaginary line in FIG. 4. This releases the lock on the cap member 41. From this state, the cap member 41 is swung forward and downward to return it to the closed position, and the top surface of the cap member 41 is pressed down. A return mechanism (not shown) extends the sliding portion 45a as shown by the solid line in FIG. 4, and the cap member 41 is locked. The operating element 55 is swung downward via the interlocking member 51, which is interlocked with this movement.

[0036] The tank cap 40 includes a locking mechanism 70 that locks the operation (movement) of the operating mechanism 50. 6 and 7 are cross-sectional views showing the operating mechanism 50 and the locking mechanism 70. Fig. 6 shows a state in which operation of the operating mechanism 50 is restricted by the locking mechanism 70. Fig. 7 shows a state in which the restriction by the locking mechanism 70 is released and the operating mechanism 50 is operated. The locking mechanism 70 is composed of the above-mentioned operating mechanism 50, a first regulating body 71 capable of regulating the operation of the operating mechanism 50, a second regulating body 72 capable of regulating the operation of the operating mechanism 50, a solenoid 73 that operates the first regulating body 71, and a regulating body holder 74 that holds the second regulating body 72.

[0037] The operation interlocking member 56 and the operation biasing member 57 of the operating mechanism 50, and the locking mechanism 70 are disposed in the space 60. The operation interlocking member 56 moves in the vehicle width direction (horizontal direction) in conjunction with the operation of the operating element 55. The movement direction D of the operation interlocking member 56 is the vehicle width direction, but this movement 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 that extends 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 by, for example, a guide portion (not shown) provided on the side surface of the surrounding portion 42a of the cap member 41.

[0038] The tip 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 operating element 55 . The distal end 56a of the operation interlocking member 56 is formed in a tapered shape that becomes smaller in diameter toward the distal end. The interlocking member engaging portion 58a of the first protrusion 58 is a hole that engages with the tip portion 56a. The inner surface of the interlocking member engaging portion 58a is formed in a tapered shape that follows the slope of the tip portion 56a.

[0039] The operation biasing member 57 biases the operation interlocking member 56 toward the first protrusion 58 so that the tip portion 56a engages with 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 face of the base end portion of the operation interlocking member 56, and the other end of the operation biasing member 57 is supported by a support portion 61 (FIG. 4). The support portion 61 is, for example, a protrusion provided on the side surface of the surrounding portion 42a of the cap member 41. The operation biasing member 57 is compressed between the support portion 61 and the operation biasing member 57 in the axial direction.

[0040] The operation interlocking member 56 has an engaging portion 56b that engages with the first restrictor 71. The engaging portion 56b is a hole that passes through the operation interlocking member 56 in the vertical direction. The engaging portion 56b is provided between the tip end portion 56a and the operation biasing member 57 in the axial direction of the operation interlocking member 56.

[0041] The first restricting body 71 and the solenoid 73 constitute a solenoid actuator 75. The solenoid actuator 75 is driven by the control unit 33. The solenoid actuator 75 is fixed to the cap support member 42, for example. The first restricting body 71 is a shaft-shaped member that extends in the vertical direction. The first restricting body 71 is housed in a cylindrical case 73a of the solenoid 73. The first restricting body 71 protrudes downward from the bottom surface of the case 73a.

[0042] The first restricting body 71 is biased by a biasing member (not shown) provided 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 unit 33, the first restricting body 71 moves upward as shown in FIG. 7 due to the electromagnetic force of the solenoid 73 against the biasing force of the biasing member. The movement direction of the first restricting body 71 is the axial direction of the first restricting body 71, that is, the up-down direction. The movement direction of the first restricting body 71 is a direction perpendicular to the movement direction D of the operation interlocking member 56.

[0043] The first restricting body 71 and the solenoid 73 are disposed above the operation interlocking member 56, and overlap the operation interlocking member 56 from above in a plan view. The first restricting body 71 moves between a restricting position where the operation of the operating mechanism 50 is restricted and a permitting position where the operation of the operating mechanism 50 is permitted. When the solenoid 73 is not energized, the first restricting body 71 is located in the restricting position as shown in Fig. 6. In the restricting position, the first restricting body 71 engages with the engaging portion 56b of the operation interlocking member 56 from above, restricting the movement of the operation interlocking member 56 in the movement direction D.

[0044] When the solenoid 73 is energized, the first restricting body 71 is located in the permitted position as shown in Fig. 7. At the permitted position, the first restricting body 71 moves upward relative to the restricted position and disengages from the engaging portion 56b. This allows the operation interlocking member 56 to move in the movement direction D.

[0045] FIG. 8 is a cross-sectional view showing a state in which the second restrictor 72 has moved upward. 6 and 8, the second regulating body 72 and the regulating body holder 74 are disposed below the operation interlocking member 56 and overlap the operation interlocking member 56 from below in a plan view. The second regulating body 72 and the regulating body holder 74 are provided so as to face the first regulating body 71 in the movement direction of the first regulating body 71. The second regulating body 72 overlaps the first regulating body 71 and the solenoid 73 when viewed in the movement direction of the first regulating body 71 (up and down direction).

[0046] The regulator holder 74 is a cylindrical member having a holding hole 74a extending vertically. The lower end of the holding hole 74a is closed and the upper end of the holding hole 74a is open upward. The regulator holder 74 is fixed to the cap support member 42, for example. The second restricting body 72 is a shaft-shaped member that extends in the vertical direction. The second restricting body 72 is housed in a holding hole 74a and is movable up and down along the holding hole 74a. The second restrictor 72 is engageable from below with the engaging portion 56b of the operation interlocking member 56. The second restrictor 72 is disposed coaxially with the first restrictor 71 and is located on the axis 71a of the first restrictor 71. The solenoid 73, the first restrictor 71, the operation interlocking member 56, and the second restrictor 72 are arranged in this order from the upper surface side, which is the outer surface of the fuel tank 29, downward.

[0047] The second restricting body 72 moves between a second restricting position that restricts the operation of the operating mechanism 50 and a second allowing 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. In the state shown in Fig. 6, the second restricting body 72 is located in the second permissible position. In the second permissible position, the second restricting body 72 is located 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 the movement of the operation interlocking member 56. The second restricting body 72 is normally positioned in the second permissible position by the action of gravity.

[0048] 8, the second restricting body 72 is located at the second restricting position. At the second restricting position, the second restricting body 72 moves upward relative to the second permissible position and engages with the engaging portion 56b of the operation interlocking member 56 from below. This restricts the movement of the operation interlocking member 56 in the movement direction D. The second restriction position is the limit position for upward movement of the second restriction body 72. For example, a flange portion provided at the bottom of the second restriction body 72 abuts against a part of the restriction body holder 74, thereby restricting upward movement of the second restriction body 72 beyond the second restriction position.

[0049] The first restricting body 71 and the second restricting body 72 are made of a ferromagnetic material, for example, an iron-based material. The solenoid actuator 75 and the sensor 52 are electrical components.

[0050] Here, the operations of the operating mechanism 50 and the locking mechanism 70 will be described. 3 to 5, when the operator 55 of the operating mechanism 50 is not operated, the operation interlocking member 56 is engaged with the interlocking member engaging portion 58a of the first protrusion 58 of the operator 55, as shown in Fig. 6. In this state, the first restricting body 71 is engaged with the engaging portion 56b and is in the restricting position, so that the operation interlocking member 56 cannot move in the movement direction D. 6, operation interlocking member 56 engaged with interlocking member engaging portion 58a of operating element 55 cannot move in movement direction D, and therefore operating element 55 cannot move upward. Therefore, the operator cannot operate operating element 55 to swing upward.

[0051] The control unit 33 receives an authentication ID code from a smart key (not shown) carried by the operator via the antenna and determines whether the ID code is legitimate. If the control unit 33 determines that the ID code is legitimate, it drives the solenoid 73 to move the first restricting body 71 to the permitted position as shown in FIG. 7. This releases the engagement of the first restricting body 71 with the engaging portion 56b, allowing the operation interlocking member 56 to move in the movement direction D and the operating element 55 to swing upward.

[0052] Next, the operator grasps, for example, overlapping portion 55b and swings operator 55 upward around swing axis 55a as shown by the imaginary line in Figure 4. As a result, the operation of operator 55 is transmitted to fuel filler neck locking member 45 via interlocking member 51, and the lock on cap member 41 by fuel filler neck locking member 45 is released. In this state, the operator can open cap member 41 and fill fuel through fuel filler neck 36.

[0053] When the operating element 55 is operated to swing upward, the interlocking member engaging portion 58a of the first protrusion 58 also moves upward, as shown in Fig. 7. As the interlocking member engaging portion 58a moves upward, the tip end 56a of the operation interlocking member 56 is pushed by the slope of the interlocking member engaging portion 58a, and the operation interlocking member 56 moves in the movement direction D. This causes the operation interlocking member 56 to disengage from the interlocking member engaging portion 58a.

[0054] For example, after refueling, the operator swings the cap member 41 downward to place the cap member 41 in the closed position. The operator then presses down on the top surface of cap member 41. This causes a return mechanism (not shown) to extend slide portion 45a of fuel filler neck lock member 45 as shown by the solid line in FIG. 4. This movement of fuel filler neck lock member 45 is transmitted to operator 55 via interlocking member 51, causing operator 55 to swing downward. Cap member 41 is locked by fuel filler neck lock member 45.

[0055] When the operating element 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 control unit 33 drives the solenoid 73 to move the first regulating body 71 to the regulating position and causes the first regulating body 71 to engage with the engaging portion 56b of the operation interlocking member 56. As a result, operation by the operating element 55 is once again restricted.

[0056] As shown in FIG. 2, a tank bag 76 capable of storing items 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 a magnet 76 a provided on the lower surface of the tank bag 76 .

[0057] 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 outside the lock mechanism 70. It is conceivable that the first regulating body 71, which is a ferromagnetic body, is pulled upward by an external magnetic force M as an external force and forcibly moved to the allowable position as shown in FIG. 8, even if the solenoid 73 is not energized. In this case, the external magnetic force M also acts on the second regulating body 72, and the second regulating body 72 is pulled upward by the external magnetic force M and is positioned at the second regulating position as shown in Fig. 8. This restricts the movement of the operation interlocking member 56 in the movement direction D, and restricts the operation of the operating element 55.

[0058] That is, in the lock mechanism 70, even if the first restricting body 71 is forcibly positioned at the permitted position by the external magnetic force M, the operation of the operating element 55 can be restricted by the second restricting body 72 that is actuated by the external magnetic force M. This makes it possible to prevent the operating element 55 from being operated accidentally. Furthermore, even if a third party applies an external magnetic force M other than that of the tank bag 76 to the lock mechanism 70, the second restricting body 72 can restrict the operation of the operating element 55. This makes it possible to prevent theft of fuel from the fuel tank 29.

[0059] The first restricting body 71 protrudes downward from the lower 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 disposed in the space 60 within the cap storage recess 35. Therefore, even without providing a special structure around the tank cap 40, it is possible to prevent the first restricting body 71, the solenoid 73, the second restricting body 72, the operation interlocking member 56, and the operation biasing member 57 from being exposed to the fuel around the fuel filler opening 36.

[0060] As described above, according to an embodiment to which the present invention is applied, the locking mechanism 70 comprises an operating mechanism 50, a first regulating body 71 that moves to a regulating position that regulates the operation of the operating mechanism 50 and an allowable position that allows the operation of the operating mechanism 50, and a solenoid 73 that operates the first regulating body 71, and is provided with a second regulating body 72 that can move separately from the first regulating body 71 in the movement direction of the first regulating body 71, and when the first regulating body 71 moves to the allowable position, the second regulating body 72 can be moved by the second regulating body 72 to a second regulating position that regulates the operation of the operating mechanism 50. According to this configuration, when the first restricting body 71 is moved to the permitted position by an external force, the second restricting body 72 can move to the second restricting position to restrict the operation of the operating mechanism 50. This prevents the locking mechanism 70 from being released by an external force, improving theft prevention. Furthermore, because the above structure ensures anti-theft performance, the solenoid 73 and the first restrictor 71 can be disposed near the top surface of the fuel tank 29 with the axis 71a oriented vertically, providing greater freedom in the placement of the solenoid 73 and the first restrictor 71. Also, there is no need to construct the solenoid 73 and the first restrictor 71 from materials that are less susceptible to the effects of external magnetic force M, providing greater freedom in design. Furthermore, there is no need to provide covers as dedicated peripheral parts that cover the solenoid 73 and the first restrictor 71 to prevent them from being affected by external magnetic force M, providing greater freedom in design.

[0061] Furthermore, when the first restricting body 71 is moved to the permitting position by an external magnetic force M acting from outside the locking mechanism 70, the second restricting body 72 is moved to the second restricting position by the external magnetic force M. According to this configuration, when the first restricting body 71 is moved to the allowing position by the external magnetic force M, the second restricting body 72 is moved to the second restricting position by the external magnetic force M. Therefore, it is possible to prevent the locking mechanism 70 from being unlocked by the external magnetic force M. Furthermore, because the operation of the operating mechanism 50 can be restricted by the second restricting body 72, there is no need to construct the first restricting body 71 from a special material that is not easily affected by magnetic force or to provide a protective member that blocks the external magnetic force M, thereby simplifying the structure. Furthermore, because the first restricting body 71 and the solenoid 73 can be disposed even in a location that is affected by the external magnetic force M, the degree of freedom in the placement of the first restricting body 71 and the solenoid 73 is improved. This makes it easier to route the wiring for the solenoid 73, for example.

[0062] Furthermore, the second restricting body 72 overlaps the first restricting body 71 and the solenoid 73 when viewed in the direction of movement of the first restricting body 71. According to this configuration, the external magnetic force M that the first restricting body 71 and the solenoid 73 receive is likely to also act on the second restricting body 72. Therefore, the second restricting body 72 can be effectively moved to the second restricting position.

[0063] Furthermore, the first restricting body 71 and the second restricting body 72 move up and down during operation, and the first restricting body 71 moves upward from the restricting position to be positioned at the permitting position. According to this configuration, the first restricting body 71 is positioned facing downward, and water and dust can be prevented from entering the solenoid 73 via the first restricting body 71.

[0064] The locking mechanism 70 is provided on the tank cap 40 that closes the fuel filler opening 36 of the fuel tank 29 of the saddle-ride type vehicle 10, and the locking mechanism 70 locks the tank cap 40 against opening and closing. According to this configuration, the lock on the opening and closing of the tank cap 40 can be prevented from being released, and the anti-theft properties of the fuel tank 29 can be improved.

[0065] Furthermore, a cap storage recess 35 is provided on the outer surface of the fuel tank 29 outside the fuel filler opening 36, and the first restricting body 71 and the second restricting body 72 are disposed in the cap storage recess 35. According to this configuration, the first and second restricting bodies 71 and 72 are disposed in the cap receiving recess 35, so that the first and second restricting bodies 71 and 72 can be prevented from being exposed to the fuel in the fuel tank 29.

[0066] In addition, the solenoid 73, the first regulating body 71, and the second regulating body 72 are arranged in this order from the outer surface side of the fuel tank 29 downward, and the first regulating body 71 is moved downward from the allowable position by the biasing force of the biasing member provided in the solenoid 73, and is positioned at the regulating position. With this configuration, first restricting body 71 moves downward to the restricted position, and therefore gravity can be used in addition to the biasing force of the biasing member to move first restricting body 71 to the restricted position. Furthermore, because the biasing force of the biasing member can be reduced, the force required to move first restricting body 71 from the restricted position to the permitted position can be reduced, allowing for power saving and miniaturization of solenoid 73.

[0067] Furthermore, when in the regulating position, the first regulating body 71 engages with an engaging portion 56b provided on the operating mechanism 50, and the engaging portion 56b is a hole that penetrates the operating mechanism 50 in the movement direction of the first regulating body 71, and when in the second regulating position, the second regulating body 72 engages with the engaging portion 56b. According to this configuration, the first and second restricting bodies 71 and 72 restrict the operation of the operating mechanism 50 by engaging with the engaging portion 56b, which is the same hole provided in the operating mechanism 50. This allows for a simplified structure.

[0068] The above-described embodiment shows one mode in which the present invention is applied, and the present invention is not limited to the above-described embodiment. In the above embodiment, the second regulating body 72 is described as overlapping the first regulating body 71 and the solenoid 73 when viewed in the movement direction of the first regulating body 71, but the present invention is not limited to this. The second regulating body 72 may overlap at least one of the first regulating body 71 and the solenoid 73. In the above embodiment, the first and second restricting bodies 71 and 72 are described as engaging with the same hole, that is, the engaging portion 56b, provided in the operation interlocking member 56, but the present invention is not limited to this. The second restricting body 72 may be engaged with an engaging portion other than the engaging portion 56b in the operation interlocking member 56 to restrict the movement of the operation interlocking member 56. In the above embodiment, the first and second restricting bodies 71 and 72 restrict the operation of the operating mechanism 50 by engaging with the operation interlocking member 56 provided separately from the operating element 55, but the present invention is not limited to this. For example, the first and second restricting bodies may restrict the operation of the operating mechanism by engaging with an engaging portion provided integrally with the operating element. Furthermore, in the above embodiment, the operating mechanism 50 is operated by an operator, but this is not limiting, and the operating mechanism 50 may also be operated by an actuator. Furthermore, in the above embodiment, a saddle-type vehicle 10, which is a motorcycle, has been used as an example of a vehicle, but the present invention is not limited to this, and the present invention is applicable to three-wheeled vehicles having two front wheels or two rear wheels, and vehicles having four or more wheels.

[0069] [Second embodiment] A second embodiment to which the present invention is applied will be described below with reference to Figures 9 and 10. In this second embodiment, parts configured in the same manner as in the above embodiment (first embodiment) are given the same reference numerals and descriptions thereof will be omitted. The second embodiment differs from the above-described embodiment in that a magnetic force transmission member that transmits the external magnetic force M to the second restricting body 272 is provided.

[0070] Fig. 9 is a cross-sectional view showing the operating mechanism 250 and the locking mechanism 270 in the second embodiment. Fig. 9 shows a state in which the operation of the operating mechanism 250 is restricted by the locking mechanism 270. Fig. 10 is a cross-sectional view showing a state in which the second restricting body 272 has moved upward.

[0071] The locking mechanism 270 is composed of an operating mechanism 250, a first regulating body 71, a solenoid 73, a second regulating body 272 that can regulate the operation of the operating mechanism 250, a regulating body holder 274 that holds the second regulating body 272, and a magnetic force transmission member 280 that transmits external magnetic force M to the second regulating body 272.

[0072] The operating mechanism 250 includes an operator 55, an operation interlocking member 256 connected to the operator 55 and moving in conjunction with the operation of the operator 55, and an operation biasing member 57. The operation interlocking member 256 is a shaft-shaped member extending in the movement direction D, and includes a tip portion 56a and an engagement portion 56b. The operation interlocking member 256 is urged toward the interlocking member engaging portion 58a by an operation urging member 57 connected to the end face of the base end of the operation interlocking member 256, and the tip end 56a engages with the interlocking member engaging portion 58a.

[0073] The first restricting body 71 and the solenoid 73 are disposed above the operation interlocking member 256, and in a plan view overlap the operation interlocking member 256 from above. The first restricting body 71 is engageable with the engaging portion 56b from above.

[0074] The second restrictor 272 and the restrictor holder 274 are the same as the second restrictor 72 and the restrictor holder 74 of the above embodiment, but are arranged in different positions, and therefore will be described with different reference numerals. The second regulating body 272 and the regulating body holder 274 are disposed below the operation interlocking member 256, and overlap the operation interlocking member 256 from below in a plan view. The second regulating body 272 and the regulating body holder 274 are provided so as to face the first regulating body 71 in the movement direction of the first regulating body 71. The second restricting body 272 and the restricting body holder 274 are disposed offset toward the first protrusion 58 relative to the first restricting body 71 in the movement direction D of the operation interlocking member 256. In other words, the second restricting body 272 is disposed offset in the movement direction D relative to the engaging portion 56b.

[0075] The operation interlocking member 256 has a second engagement portion 256b on its underside that can be engaged with the second restricting body 272. The second engagement portion 256b is a hole that can be engaged with the second restricting body 272 from below. The second engagement portion 256b is arranged offset toward the tip end 56a with respect to the engagement portion 56b in the movement direction D.

[0076] The operation interlocking member 256 has a recess 256d extending in the movement direction D. The recess 256d is a groove formed on the upper surface of the operation interlocking member 256 and extending in the movement direction D. The recess 256d is a groove that allows the magnetic force transmission member 280 to escape. The recess 256d is positioned offset toward the tip end 56a with respect to the engagement portion 56b. A portion of the recess 256d communicates with the second engagement portion 256b.

[0077] The magnetic force transmission member 280 is a rod-shaped member that extends vertically. The magnetic force transmission member 280 is disposed parallel to the first restricting body 71 and the second restricting body 272. The magnetic force transmission member 280 is disposed in the space 60 adjacent to the solenoid 73. The magnetic force transmission member 280 is disposed between the solenoid 73 and the first protrusion 58.

[0078] The magnetic force transmission member 280 is disposed above the operation interlocking member 256. A lower portion 280a of the magnetic force transmission member 280 enters the recess 256d from above and is positioned inside the operation interlocking member 256. The magnetic force transmission member 280 does not come into contact with the operation interlocking member 256 because it is hidden within the recess 256d. The magnetic force transmission member 280 is disposed so as to overlap the second restricting body 272 from above. Specifically, the magnetic force transmission member 280 is disposed in a coaxial positional relationship with the second restricting body 272. By being disposed within the recess 256d, the magnetic force transmission member 280 is positioned near the second restricting body 272 in the axial direction of the second restricting body 272. The magnetic force transmission member 280 is a ferromagnetic body, and is made of, for example, an iron-based material.

[0079] 9, the first restricting body 71 is positioned at the restricting position and engages with the engaging portion 56b, thereby restricting the movement of the operation interlocking member 256 and restricting the operation of the operating mechanism 250. In this state, the second restricting body 272 is positioned directly below the second engaging portion 256b and is in the second permissible position.

[0080] 10, the first restricting body 71 is pulled upward by the external magnetic force M and forcibly moved to the permitted position. In this case, the external magnetic force M also acts on the second restricting body 272 via the magnetic force transmission member 280, and the second restricting body 272 is pulled upward by the external magnetic force M. As a result, the second restricting body 272 is positioned at the second restricting position and engages with the second engaging portion 256b to restrict the movement of the operation interlocking member 256. Therefore, the operation of the operating mechanism 250 is restricted.

[0081] As described above, according to the second embodiment of the present invention, the first regulating body 71 and the second regulating body 272 are magnetic bodies, and a magnetic force transmission member 280 that transmits the external magnetic force M to the second regulating body 272 is arranged near the second regulating body 272. According to this configuration, the external magnetic force M can be effectively transmitted to the second restricting body 272 by the magnetic force transmitting member 280, so that the second restricting body 272 can be moved to the second restricting position and the unlocking can be prevented.

[0082] [Configuration supported by the above embodiment] The above embodiment supports the following configurations.

[0083] (Configuration 1) A locking mechanism comprising an operating mechanism, a first regulating body that moves to a regulating position that regulates the operation of the operating mechanism and a permissible position that permits the operation of the operating mechanism, and a solenoid that operates the first regulating body, characterized in that a second regulating body is provided that is movable separately from the first regulating body in the movement direction of the first regulating body, and the second regulating body can be moved by the second regulating body to a second regulating position that regulates the operation of the operating mechanism when the first regulating body moves to the permissible position. With this configuration, when the first restricting body is moved to the permitted position by an external force, the second restricting body can move to the second restricting position to restrict the operation of the operating mechanism. This prevents the lock from being released by an external force, improving theft prevention. It also improves the design freedom of the solenoid and peripheral components.

[0084] (Configuration 2) The locking mechanism described in Configuration 1, characterized in that the second regulating body is moved to the second regulating position by an external magnetic force acting from outside the locking mechanism when the first regulating body is moved to the permissible position by the external magnetic force. According to this configuration, when the first restricting body is moved to the permitting position by an external magnetic force, the second restricting body is moved to the second restricting position by the external magnetic force, which makes it possible to prevent the locking mechanism from being unlocked by the external magnetic force.

[0085] (Configuration 3) The locking mechanism described in Configuration 2, characterized in that the first regulating body and the second regulating body are magnetic bodies, and a magnetic force transmission member that transmits the external magnetic force to the second regulating body is arranged near the second regulating body.

[0086] (Configuration 4) The locking mechanism according to configuration 2 or 3, wherein the second regulating body overlaps with at least one of the first regulating body and the solenoid when viewed in the direction of movement of the first regulating body. With this configuration, the external magnetic force that the first restricting body and the solenoid receive is more likely to act on the second restricting body, thereby effectively moving the second restricting body to the second restricting position.

[0087] (Configuration 5) A locking mechanism described in any one of configurations 1 to 4, characterized in that the first regulating body and the second regulating body move in an up and down direction during operation, and the first regulating body moves upward from the regulating position to be positioned at the permissible position. According to this configuration, the first restricting body is positioned facing downward, and it is possible to prevent water and dust from entering the solenoid via the first restricting body.

[0088] (Configuration 6) The locking mechanism according to any one of configurations 1 to 5, characterized in that the locking mechanism is provided on a tank cap that closes a fuel filler opening of a fuel tank of a vehicle, and the locking mechanism locks the opening and closing of the tank cap.

[0089] (Configuration 7) The locking mechanism according to configuration 6, wherein a recess is provided on the outer surface of the fuel tank outside the filler opening, and the first and second restricting bodies are disposed in the recess. This configuration can prevent the tank cap from being locked and unlocked, improving the anti-theft capabilities of the fuel tank.

[0090] (Configuration 8) A locking mechanism according to configuration 6 or 7, characterized in that the solenoid, the first regulating body, and the second regulating body are arranged in this order from the outer surface side of the fuel tank downward, and the first regulating body is positioned at the regulating position by moving downward from the allowable position due to the biasing force of a biasing member provided in the solenoid. According to this configuration, since the first and second restricting bodies are disposed in the recessed portions, it is possible to prevent the first and second restricting bodies from being exposed to the fuel in the fuel tank.

[0091] (Configuration 9) A locking mechanism described in any one of configurations 1 to 8, characterized in that the first regulating body engages with an engaging portion provided on the operating mechanism at the regulating position, the engaging portion being a hole that penetrates the operating mechanism in the direction of movement of the first regulating body, and the second regulating body engages with the engaging portion at the second regulating position. According to this configuration, the first and second restricting bodies restrict the operation of the operating mechanism by engaging with the same hole provided in the operating mechanism, which simplifies the structure.
