Below by the process of brief description fueling.

In Fig. 2, when fueling, after vehicle is parked in petrol service station, when opening operator's saddle door lock (not shown), the latch-release of lock pin 31 and fuel cap 15.But fuel cap 15 is not opened.When next using hand push fuel cap 15, fuel cap 15 is elected device 33 and is promoted and automatically open, and is then manually further opened (seeing Fig. 1).In the time will closing fuel cap 15, the fuel cap 15 of opening is overcome to the elastic force of electing device 33 and close.Then, the operator's saddle door lock is closed, lock pin 31 enters in the lock opening features 68 of impact member 26, and fuel cap 15 is locked.

The operation of the lid structure of the fuel filler tube opening that is used for the first embodiment below will be described.

As shown in Figure 1, when the actuation member 27 that is provided for opening and closing fuel cap 15 engages with the copulational protuberance 63 that is arranged on fuel adapter 16 1 sides, actuation member 27 is applied to the motivator of closing on fuel cap 15 directions, so the state of closing is not opened and remained on to fuel cap 15.Therefore, as described in the prior art part, do not need to use the member such as S shape spring to make the hinge 22 that fuel cap can open and close apply motivator to supporting fuel cap 15, do not need to form the space of placing S shape spring yet.Therefore, the size of fuel adapter 16 can reduce, and its productive costs also can be reduced.

When the impact member 26 on being arranged on fuel cap 15 and actuation member 27 engage with the copulational protuberance 63 that is arranged on body panel 13 (fuel adapter a 16) side, in the situation that the locking of door lock has been disengaged the motivator that fuel cap 15 is actuated member 27, on closing direction, actuate, prevent that fuel cap 15 from opening with running counter to the automotive occupant intention.

As shown in Figure 7, when closing fuel cap 15, actuation member 27 contacts with the copulational protuberance 63 that is positioned at body panel 13 1 sides, as shown in solid line.Along with further closing of fuel cap 15, the extension component 75 of actuation member 27 or extruder member 76 elastic deformations also start to open as shown in arrow b1.When extruder member 76 process copulational protuberance 63, because extruder member applies squeese pressure by elastic force (motivator) (on the direction of arrow b2), fuel cap 15 continues to rotate in (on the direction of arrow a2) on closing direction under the effect of the component of the hand pressure that continues and motivator.When election device 33 arrival of pressurized push state (seeing Fig. 4), because electing the compression coil spring 53 of device 33 does not extend, even so hand is removed from the fuel cap 15 that is in fuel cap off position E as shown in Figure 1, fuel cap 15 still is in closed condition.

When fuel cap 15 was in closed condition (fuel cap off position E), extruder member 76 or extension component 75 engaged with copulational protuberance 63, so actuation member 27 applies motivator to fuel cap 15.Therefore in the closing process of fuel cap 15, actuation member 27 is not closed fuel cap 15 automatically.Therefore can prevent that object is sandwiched between fuel cap 15 and fuel adapter 16.

In addition, when fuel cap 15 was in closed condition, actuation member 27 was drawn fuel cap 15 on closing direction, and this inside pulling force (motivator) makes fuel cap 15 be pressed against and elects on device 33.Therefore, when by the locking of removing door lock, removing the locking of fuel cap 15, fuel cap 15 can be because the effect that for example is subject to (on arrow b3 direction) centnifugal force G when vehicle is turned right is opened.In addition, can prevent that fuel cap 15 is at the light exercise that opens and closes on direction, and can prevent fuel cap 15 vibrations (making a sound).

In the situation that fuel cap 15 non-lockings, even when fuel cap 15 was sprayed by water in the carwash process, fuel cap 15 can not opened yet.

Because the motivator of actuation member 27 is set to less than the tensile force of electing device 33, so copulational protuberance 63 can overcome motivator by the tensile force that forms when electing device 33 projection, as shown in arrow b1, move through the extruder member 76 of actuation member 27, fuel cap 15 can automatically be opened.

In fuel adapter 16, need in the first wall components 41 of an end of side member 35, not be formed for holding the spill housing parts of hinge or spring.Therefore, the size of fuel adapter 16 can reduce, and its productive costs also can reduce.

Because actuation member 27 mainly consists of fixed parts 74, extension component 75 and extruder member 76, its structure is simplified.

When the opening between the extruder member 76 of actuation member 27 was larger, extension component 75 contacted and prevents that extruder member 76 from opening with lock opening features 68, therefore can keep motivator.

In fuel cap lockout mechanism 23, because actuation member link 57 is formed in impact member 26, and the first tab portion 81 and the second tab portion 82 are formed in actuation member 27, so actuation member 27 can be only before being fixed by the first tab portion 81 and the second tab portion 82 are hooked on actuation member link 57 and engage, and can easily assemble actuation member 27.

Because lock opening features 68 prevents the rotation when actuation member 27 is connected to impact member 26, even so be subject to also can preventing when using outside thread member 71 to carry out the fixing power on rotation direction of screw thread that in actuation member 27 actuation member 27 from rotating, and can easily actuation member 27 and impact member 26 be assembled.

As shown in figure 10, the side member 147 of fuel adapter 116 is formed by the first side wall 177, the second sidewall 178, the 3rd sidewall 181 and the 4th sidewall 182.Fuel adapter 116 has the bottom part 145 continuous with side member 147.The opening 166 that enters that is used for the lid engaging gear 148 of connection cover locking device 122 is formed on the first side wall 177.

Election device 118 with existing structure produces be used to the elastic force that overcomes actuation gear 156 with the releasing power of opening of the joint of removing impact member 151 and copulational protuberance 155 to push open, and elects device 118 and open releasing power and be closed when with copulational protuberance 155, engaging generation less than the confining force of closing of opening releasing power when the fuel cap 115 of opening overcomes.

As shown in Figure 11,12 and 13, lid engaging gear 148 comprises: the columniform base caps 185 that is connected to fuel adapter 116; The bar that is arranged in base caps 185 receives cylindrical member 86; Be contained in actuation gear 156 and copulational protuberance 155 in the tube body 187 that bar receives cylindrical member 186; And the lock pin 165 in insertion copulational protuberance 155.

Bar receives cylindrical member 186 and has lock pin receiving-member 188 and the first tab portion 191 that forms concentrically with tube body 187.

Base caps 185 has for the flange 192 that opening 166 engages that enters with being formed on fuel adapter 116; The second tab portion 193; And for bar, receiving the first hole parts 194 that the first tab portion 191 of cylindrical member 186 engages.The second tab portion 193 is elastomeric, and base caps 185 is clamped and is connected to fuel adapter 116 by flange 192 and the second tab portion 193 by fuel adapter 116.Copulational protuberance 155 can advance and retract by the second hole parts 195, and the second hole parts 195 receive with bar the central authorities that cylindrical member 186 is formed on flange 192 concentrically.

the concrete structure of copulational protuberance 155 is, contact component 161 is formed on the front end place of engage body 197 towards impact member 151, make the pin-and-hole 201 that lock pin 165 can slide form concentrically with the axis 198 of attachment 197, edge joint by the second hole parts 195 with base caps 185 is formed on the central authorities of longitudinal direction with the stop shoulder 202 of the effect of playing retainer, the pin insertion convergent parts 204 continuous with pin-and-hole 201 are formed on rear end, and with pin, insert the continuous elastic body receiving end 205 of convergent parts 204 and be formed the end that bolt-lock is lived actuation gear 156.Elastic body receiving end 205 receives the motivator of actuation gear 156.Actuation gear 156 is Compress Springs for example.

The motivator of actuation gear 156 (spring force) produces less than the component of force of opening releasing power of electing device 118 when lid lock apparatus 122 non-locking, and is set to produce the component of force of closing confining force greater than electing device 118.

Greater than the component of force of closing confining force, it is the load that the hydraulic pressure while being enough to prevent fuel cap 115 by the centnifugal force G that for example produces at Ackermann steer angle or high Pressure-washing apparatus is opened.

It less than the component of force of opening releasing power, is the load that makes fuel cap 115 to be elected device 118 to open.

Below with reference to the operation of Figure 14 A to 14C explanation according to the structure of the lid for the fuel adding opening of the second embodiment.

As shown in Figure 14 A, fuel cap 115 is by being locked and be fixed to body panel 113 by lid lock apparatus 122.While after fuel cap 115 has been closed, near the switch operator's saddle being adjusted to " locking ", lock pin 165 advances (on arrow d1 direction) by lock driver element 164 (Fig. 3), and lock pin 165 passes through the lockhole parts 172 of impact member 151 and engages with lockhole parts 172, thus locking fuel cap 115.

In the situation that open fuel cap 115, when aforementioned switch was adjusted to " release ", the locking by lock pin 165 was disengaged (Figure 14 B).

Due to the contact component 161 by by copulational protuberance 155 (the second inclined surface 162) be pushed against impact member 151 contact component 157 (the first inclined surface 158) and by fuel cap 115 bolt-locks on body panel 113, so use, actuate spring so that fuel cap 115 bolt-locks to the structure on body panel 113 is arranged in single lid lock apparatus 122.Therefore, fuel adding vent cover structure 100 can be simplified, and the size of fuel adding vent cover structure 100 can reduce.

Specifically, when the motivator when copulational protuberance 155 by actuation gear 156 promotes to be arranged on the impact member 151 on fuel cap 115 as shown in arrow d2, component of force acts on the first inclined surface 158 of impact member 151 towards the inboard of body panel 113 (on the direction of arrow d3) as shown in arrow d4, so fuel cap 115 is pulled to the inboard (on the direction of arrow d3) of body panel 113.Because elect device 118, with retracted mode, produce (on arrow d5 direction) and close confining force pushing, so fuel cap 115 is pushed to the outside (on arrow d6 direction) of body panel 113.At this moment, (component of force and close confining force) is all balances because default power, so fuel cap 115 keeps closing at off position E.

In fuel adding vent cover structure 100 as shown in Figure 14B, even because because above-mentioned equilibrium of forces makes the distal component of copulational protuberance 155, keep engaging with impact member 151 when the locking of fuel cap 115 is disengaged, so fuel cap 115 can not opened.Therefore, even when the locking of fuel cap 115 is disengaged, also can prevent near the object interference with the fuel cap 115 in body panel 113 outsides.

When after latch-release, next using hand H (on arrow d7 direction) pushing fuel cap 115, fuel cap 115 inwardly move (state as shown in long and two-short dash line) enter (on arrow d3 direction) in body panel 113, impact member 151 is inwardly moved when by detaching gear 159, preventing from interfering with copulational protuberance 155.

As shown in Figure 14 C, the opening of (on arrow d8 direction) that starts to be elected devices 118 when fuel cap 115 removed while trying hard to recommend out, the first inclined surface 158 of impact member 151 moves when the contact component 161 with copulational protuberance 155 contacts, and impact member 151 cause copulational protuberance 155 to overcome the elastic force of actuation gear 156 and (on arrow d9 direction) retract.Therefore fuel cap 115 opens to minimum open position Ka.

When after fueling, fuel cap 115 starts to close, carry out opposite motion; That is: the transformation of generation from the state shown in Figure 14 C to the state shown in Figure 14 B, and the contact component 157 of impact member 151 (the first inclined surface 158) starts to arrive the contact component 161 (the second inclined surface 162) of copulational protuberance 155.Because the contact component 161 of the first inclined surface 158 of impact member 151 and copulational protuberance 155 slides and engages because the motion of copulational protuberance 155 on direction of propulsion abuts against each other, so fuel cap 115 can be actuated on closing direction, and fuel cap 115 is automatically closed.

In the fuel adding vent cover structure 100 of above-mentioned configuration, copulational protuberance 155 can be actuated fuel cap 115 towards impact member 151 (on arrow d2 direction) motion on closing direction (arrow d3 direction) because actuation gear 156 is set to by actuating copulational protuberance 155, so need to not provide spring on closing direction, to actuate fuel cap 115 in hinge 143 (Fig. 8) side, fuel adding vent cover structure 100 can be simplified and the size of fuel adding vent cover structure 100 can reduce.

The example of lid for fuel adding opening structure of the present invention for vehicle has been described, but covering structure also can be used on non-vehicle application.
