Japanese Unexamined Patent Publication No. 2014-159673

The conventional lid device lacks the convenience of opening and closing the lid because the unlocking mechanism of the lid is limited to the unlocked state of the door lock and the unlocking response is poor.

An object to be solved by the present invention is to improve the convenience of opening and closing the lid.

The lid device according to one embodiment of the present invention is a lid device (20) that opens and closes an opening (16) provided in the vehicle body (10) for performing at least one of energy supply and external power supply. A lid (22) provided on the vehicle body so as to be displaceable between an open position for opening the door, a closed position for closing the opening, and an overstroke position located in a closing direction further than the closed position, and the above. A locking mechanism (24) that allows displacement of the lid to the overstroke position, selectively prevents displacement of the lid from the closed position to the open position, and latches the lid to the closed position, and the above. A lock drive unit (36) that drives the lock mechanism, a switch (40) that detects that the lid is displaced to the open position, the closed position, and the overstroke position, and a control that controls the lock drive unit. The control unit has a unit (54), and when the switch detects that the lid is displaced to the overstroke position, the control unit controls the lock drive unit so as to release the lock mechanism. ..

According to this configuration, the responsiveness of unlocking the lid is improved, and the convenience of opening and closing the lid is improved.

In the lid device, preferably, the control unit controls the lock drive unit so that the unlocking operation of the lock mechanism is performed over a first predetermined time.

This configuration improves the certainty of unlocking the lid.

In the lid device, preferably, the control unit includes an authentication unit (56) that performs a predetermined authentication process, and when the vehicle door lock (55) is in the locked state, the switch detects the overstroke position. At that time, the authentication process is executed, the lock drive unit is controlled so as to start the unlocking operation of the lock mechanism when the authentication process is properly completed, and when the door lock is in the unlocked state, the lock mechanism is controlled. The lock drive unit is controlled so as to start the unlocking operation of the lock mechanism when the switch detects the overstroke position without performing the authentication process.

According to this configuration, when the door lock is in the unlocked state, the responsiveness of unlocking the lid does not deteriorate, and when the door lock is in the locked state, the delay in unlocking the lid is minimized. The security of the lid device is improved.

In the lid device, preferably, after the switch detects the overstroke position, the state change of the switch is ignored until the detection of the closed position by the switch is maintained for a second predetermined time. If the authentication by the authentication unit is an OK determination, the determination is made if the authentication by the authentication unit is an NG determination until the subsequent unlocking operation of the lock mechanism by the lock drive unit is completed. Until the completion, the request for restarting the release operation of the lock mechanism is not accepted or prohibited.

According to this configuration, it is possible to prevent the door lock status confirmation and the authentication process from being started unnecessarily repeatedly every time the switch is located at the overstroke position.

In the lid device, preferably, the switch includes an operating rod (44) that is displaced by contact with the lid and a microswitch (48) that opens and closes by displacement of the operating rod.

According to this configuration, the position of the lid is reliably detected.

According to the lid device according to the present invention, the convenience of opening and closing the lid is improved.

Hereinafter, one embodiment of the lid device according to the present invention will be described with reference to FIGS. 1 to 10.

As shown in FIGS. 1 and 2, a charging box 14 having a built-in charging / power supply outlet (charging / power supply inlet) 12 is attached to the vehicle body (outer panel) 10 of a plug-in hybrid vehicle or an electric vehicle. Has been done. The charging / power supply outlet 12 is used for charging an in-vehicle battery (not shown) by an external power source and for supplying electric power to take out the electric power of the in-vehicle battery to the outside.

The charging box 14 defines a charging / power supply opening 16 that is opened toward the outside of the vehicle body 10 as an energy replenishment opening. The vehicle body 10 is provided with a lid device 20 that opens and closes the charging / power supply opening 16. The lid device 20 has a lid 22 rotatably attached to the charging box 14 by a hinge 18. The lid 22 includes a front plate 20A and a back plate 22B, and has a fully open position and an open position for opening the charging / feeding opening 16, a closing position for closing the charging / feeding opening 16, and a closing direction further than the closed position. It is possible to displace between the overstroke position located at. The open position of the lid 22 is a position slightly open from the closed position. The lid 22 is manually displaced from the open position to the fully open position, and is selectively held in the fully open position by friction of the hinge 18 or a spring (not shown). The lid 22 may be attached to the vehicle body 10 by a hinge 18.

The lid device 20 has an electric locking mechanism 24. The lock mechanism 24 includes a mounting board 26 fixed to the charging box 14 and a lock claw 30 rotatably mounted on the mounting board 26 by a support shaft 28.

The lock claw 30 has a hook shape including an inclined surface 30A and an upright surface 30B, and by selectively engaging with an engaging protrusion 34 of an operating member 32 attached to the back plate 22B, the lid 22 The displacement to the overstroke position is allowed, the displacement of the lid 22 from the closed position to the open position is selectively prevented, and the lid 22 is latched to the closed position.

An electric motor 36 forming a lock drive unit is mounted on the mounting board 26. The electric motor 36 is connected to the support shaft 28, and the lock claw 30 is engaged with the lock claw 30 by rotating the lock claw 30 counterclockwise in the figure from the illustrated lock position where the lock claw 30 is engaged with the engaging protrusion 34 by energization. It is positioned at the unlocked position where it is disengaged from the engagement with the protrusion 34. By being located at the unlocked position, the lock claw 30 allows the lid 22 to be displaced from the closed position to the open position.

The lock claw 30 is urged toward the lock position by a return spring (not shown), and returns to the lock position by the spring force of the return spring when the electric motor 36 is not energized. When the lid 22 returns from the fully open position or the open position to the closed position under the non-energized state of the electric motor 36, the lock claw 30 abuts the engaging protrusion 34 on the inclined surface 30A and the spring force of the return spring. After overcoming the engaging protrusion 34 by rotating against the above, it automatically returns to the locked position where it engages with the engaging protrusion 34 by the spring force of the return spring.

A lid switch 40 is mounted on the mounting board 26. The lid switch 40 is a rod support member 42 fixed to the mounting board 26 and an operation rod movably supported by the rod support member 42 in the axial direction (direction in which the lid 22 in the closed position is separated from the back surface). Includes 44, a rod urging spring 46 that urges the operating rod 44 toward the lid 22, and a microswitch 48 that opens and closes due to axial displacement of the operating rod.

The operating rod 44 has a shaft end 44A that comes into contact with the rod operating protrusion 38 formed on the operating member 32 so as to be separable. As a result, the rod urging spring 46 also serves as a lid urging spring that urges the lid 22 from the overstroke position in the opening direction via the operating rod 44, and the number of parts including the spring can be reduced.

The operating rod 44 has a cam portion 50 including a recess 50A in which the operator 48A of the microswitch 48 engages in an intermediate portion in the axial direction.

When the lid 22 is in the fully open position or the open position, the operating rod 44 is displaced to the rightmost side by the spring force of the rod urging spring 46 as shown in FIG. 3A, so that the cam portion 50 The recess 50A of the above is separated from the operator 48A of the microswitch 48, and the contact of the microswitch 48 is closed, so that the lid switch 40 is turned on and the terminal voltage Va becomes a low level.

When the lid 22 is in the closed position, the operating rod 44 is displaced to the left side against the spring force of the rod urging spring 46 as shown in FIG. 3 (B), so that the cam portion 50 is displaced. When the recess 50A engages with the operator 48A of the microswitch 48 and the contact of the microswitch 48 opens, the lid switch 40 is turned off and the terminal voltage Va becomes a high level.

When the lid 22 is in the overstroke position, the operating rod 44 is further displaced to the left against the spring force of the rod urging spring 46 as shown in FIG. 3C, so that the cam portion is formed. When the recess 50A of the 50 is separated from the operator 48A of the microswitch 48 and the contact of the microswitch 48 is closed, the lid switch 40 is turned on and the terminal voltage Va becomes a low level.

As shown in FIG. 2, the electric motor 36 is energized and de-energized by opening and closing a normally open type relay switch 52 provided in the power supply circuit of the battery voltage Vb. The opening and closing of the relay switch 52, that is, the on / off of the relay output is controlled by the control device 54.

The control device 54 includes a microcomputer, in which a door lock signal is input from the terminal voltage Va of the lid switch 40 and the door lock device 55 in the driver's seat, the relay output is turned on / off, and the lid is opened / closed by the indicator 58. Control the display of.

The control device 54 further includes an authentication unit 56 that authenticates a legitimate user (ID verification) by wireless communication with a portable electronic key (FOB) 60 called a smart key. The authentication unit 56 electronically performs the authentication process when the door lock device 55 is locked, that is, when the door is locked, according to a known procedure.

In the control device 54, when the door lock device 55 is in the unlocked state, that is, when the door is unlocked, the lid 22 is pushed by the user by the lid switch 40 and the lid 22 is displaced from the closed position to the overstroke position. When detected by the change from off to on of the switch 40, the relay output (on output) that closes the relay switch 52 without performing the authentication process by the authentication unit 56 is output without including a substantial delay time. The first predetermined time is Ta (about 800 ms).

As a result, when the door is unlocked, the unlocking operation of the lock mechanism 24 by the electric motor 36 is immediately started when the lid 22 is displaced from the closed position to the overstroke position. When the lock claw 30 is rotated to the unlock position by this release operation, the lid 22 can be displaced from the overstroke position to the open position via the closed position. The lid 22 displaced to the open position can be manually displaced to the fully open position, and the charging / feeding opening 16 is fully opened.

In this way, when the door is unlocked, the lid 22 in the closed position is simply pushed to the overstroke position, and the lid 22 is unlocked with good responsiveness without including a substantial waiting time (delay time). The convenience of opening and closing the lid is improved.

When the door lock device 55 is locked, that is, when the door is locked, the control device 54 turns on from the lid switch 40 off when the lid 22 is pushed by the user and the lid 22 is displaced from the closed position to the overstroke position. When it is detected by the change to, the authentication process by the authentication unit 56 is started. When the authentication process is properly completed (OK determination), the control device 54 outputs the relay output that closes the relay switch 52 at that time, that is, when the authentication of the legitimate user is completed, with a substantial delay time. It is carried out over a first predetermined time Ta (about 800 ms) without including it.

As a result, when the door is locked, the delay in unlocking the lid 22 is limited to the time required for the authentication process, and the convenience of opening and closing the lid is improved.

That is, at the time of door locking, the authentication process is started by the authentication unit 56 triggered by the displacement of the lid 22 from the closed position to the overstroke position, and when the authentication process is properly completed, the lock mechanism 24 is released by the electric motor 36. The lock claw 30 is rotated to the unlocked position, and the lock mechanism 24 is released. By releasing the lock mechanism 24, the lid 22 can be displaced from the overstroke position to the open position via the closed position. The lid 22 displaced to the open position can be manually displaced to the fully open position, and this displacement causes the charging / feeding opening 16 to be fully opened.

At the time of door lock, the control device 54 does not output a relay that closes the relay switch 52 unless the authentication process is properly completed, that is, at the time of NG determination. As a result, the lock mechanism 24 of the lid 33 is not released by a non-user whose authentication process is not properly completed, and security measures are taken.

By the above operation, when the door lock device 55 is in the unlocked state, the responsiveness of unlocking the lid 22 is not deteriorated, and when the door lock device 55 is in the locked state, the response of unlocking the lid 22 is not deteriorated. The security of the lid device 20 is improved by minimizing the deterioration of the sex.

After the lid switch 40 detects the overstroke position, that is, after the lid switch 40 changes from off to on, the control device 54 turns off the lid switch 40 for a second predetermined time Tb (about 200 ms) or more. Under flag control, the change from off to on of the lid switch 40 is ignored, and if the authentication process is OK, the lock mechanism 24 is locked by the electric motor 36. Until the release operation is completed, if the authentication process is NG determination, the request to start the release operation of the lock mechanism 24 again is not accepted or prohibited until the determination is completed. As a result, the confirmation of the door lock device 55 and the authentication process by the authentication unit 56 are not repeatedly started.

As a result, even if the lid 22 is repeatedly pushed to the overstroke position at intervals shorter than the second predetermined time Tb, the request for the release operation of the lock mechanism based on the detection of the overstroke position by the lid switch 40 is made at short time intervals. It is avoided that it is repeated unnecessarily, and the confirmation of the state of the door lock device 55, the authentication process, and the on-output of the relay switch 52 are not repeated. By this control, it is avoided that the confirmation of the door lock state and the authentication process are repeatedly started every time the lid switch 40 is positioned at the overstroke position, and the release of the lock mechanism is prevented from being delayed.

The operation of closing the lid 22 displaced to the fully open position is performed by manually returning the lid 22 to the closed position. At this time, if the on-output of the relay switch 52 by the control device 54 is completed and the lock claw 30 is automatically returned to the lock position, the lid 22 is latched to the closed position by the lock mechanism 24.

Next, each operation of the lid device 20 and control by the control device 54 will be described with reference to the tables and flowcharts shown in FIGS. 4 to 6 and the time charts shown in FIGS. 7 to 13.

The lid switch status and the open sequence flag used for controlling the lid device 20 are generated in the control device 54 according to each condition. The door status is generated by a door lock signal input to the control device 54. FOB verification is an authentication process.

The on condition of the lid switch status is that the lid switch 40 has changed from off to on. The off condition of the lid switch status is that the off state of the lid switch 40 is maintained for a second predetermined time Tb or more.

The yes condition for the open sequence flag is that the lid switch status has changed from off to on. The no condition of the open sequence flag is that the third predetermined time Tc (about 100 ms) has elapsed from the time when the relay output changes from on to off, or the determination result of the authentication process is NG determination. The change of the open sequence flag from yes to no delays by Tc for the third predetermined time from the time when the relay output changes from on to off, because the lock claw 30 returns from the unlock position to the lock position. This is to ensure that the open sequence flag changes from yes to no afterwards.

That is, the open sequence flag is set to "yes" when the lid switch status changes from off to on, as shown in the table in FIG. The request to start the unlocking operation of the lock mechanism is issued only when the open sequence flag changes from "no" to "yes" as shown in the table of FIG. Start requests are prohibited while the open sequence flag remains "no" or "yes".

As a result, even if the detection of the overstroke position by the lid switch 40 is repeated at intervals shorter than the second predetermined time Tb, the request to start the unlocking operation of the lock mechanism is unnecessarily repeated every time the overstroke position is detected. Is avoided, and the door lock status confirmation and authentication process are not started repeatedly. In particular, the long-time authentication process is not repeatedly started, and the long-time authentication process and the smooth operation are compatible.

The control device 54 executes the event routine shown in FIG. 6 only once when the open sequence flag changes from "no" to "yes".

In this event routine, first, it is determined whether or not the door status is locked (step S10). If the door status is not locked, that is, unlocked, the FOB collation (step S11) is passed and the relay output is turned on for the first predetermined time Ta (step S12).

If the door status is locked, FOB verification is performed (step S11). If the FOB collation is OK, the relay output is turned on for the first predetermined time Ta (step S12). If the FOB collation is NG, the event routine ends without turning on the relay output.

When (first predetermined time Ta + third predetermined time Tc) elapses from the on-start time of the relay output (step S13), the open sequence flag changes from "yes" to "no", and the event routine ends.

When the relay output is on, the electric motor 36 is energized, the lock claw 30 is displaced to the unlocked position, and the lock mechanism 24 is released. When the relay output is off, the electric motor 36 is not energized and the lock mechanism 24 returns to the locked position.

The relay output on condition, that is, the lock mechanism 24 release condition, is when the lid switch status changes from off to on when the open sequence flag is no and the door status is unlocked. When the door status is locked, the open sequence flag is no, and the FOB collation is normally completed (OK determination) within the specified time from the time when the lid switch status changes from off to on. The off condition of the relay output is when the first predetermined time Ta has elapsed from the time when the relay output changes from off to on.

FIG. 7 is a time chart when the door status is unlocked (when the door is unlocked).

At time point A in the process of displacement of the lid 22 from the closed position to the overstroke position, when the lid switch 40 changes from off to on, the lid switch status changes from off to on and the open sequence flag changes from no to yes. It changes and the door status confirms the door lock upon request to start unlocking. The unlock start request only occurs when the open sequence flag changes from no to yes.

Since the door status is unlocked, the relay output is turned on by the on-change of the lid switch status at the time point A without performing FOB verification. As a result, the lock mechanism 24 is immediately released at the time point A, and the lid 22 can be displaced from the overstroke position to the open position.

In the process of displacement of the lid 22 from the overstroke position to the open position, the lid switch is turned off by the position of the lid 22 in the closed position at the time point B, but the off time is less than the second predetermined time Tb. , Lid switch status does not change.

The relay output is turned off at the time point C when the first predetermined time Ta has elapsed from the time point A, and the operation of returning the lock claw 30 to the lock position starts. The open sequence flag changes from yes to no at time D when (first predetermined time Ta + third predetermined time Tc) elapses from time point A.

As a result, the lock release start request is prohibited in the period from the time point C to the time point D, that is, in the process of the lock claw 30 returning to the lock position, and the lock claw 30 is displaced to the unlock position on the way back to the lock position. Is avoided.

FIG. 8 is a time chart when the door status is locked (when the door is locked) and the FOB collation is normally completed in the shortest time Tmin (about 180 ms) (at the time of OK determination).

At time point A in the process of displacement of the lid 22 from the closed position to the overstroke position, when the lid switch 40 changes from off to on, the lid switch status changes from off to on and the open sequence flag changes from no to yes. It changes and the door lock is confirmed by the unlock start request.

When the door status is locked, FOB verification (authentication processing) is performed. At the time point E when the shortest time Tmin has elapsed from the time point A, when the FOB collation is completed with the OK determination, the relay output is turned on. As a result, the lock mechanism 24 is released at the time point E, and the lid 22 can be displaced from the overstroke position to the open position.

The relay output is turned off at the time point F when the first predetermined time Ta has elapsed from the time point E, and the operation of returning the lock claw 30 to the lock position starts. In this case, the open sequence flag changes from yes to no at the time point G when (the shortest time Tmin + the first predetermined time Ta + the third predetermined time Tc) elapses from the time point A.

FIG. 9 is a time chart when the door status is locked (when the door is locked) and the FOB collation is normally completed in the longest time Tmax (about 2000 ms) (at the time of OK determination).

At time point A in the process of displacement of the lid 22 from the closed position to the overstroke position, when the lid switch 40 changes from off to on, the lid switch status changes from off to on and the open sequence flag changes to yes. , The door lock is confirmed.

FOB verification is performed because the door status is locked. When the lid 22 returns to the closed position and the lid switch 40 is turned off at the time point H during FOB collation, the lid switch status is turned off at the time point I when the second predetermined time Tb has elapsed.

After that, at the time point J where the longest time Tmax has elapsed from the time point A, when the FOB collation is completed with the OK determination, the relay output is turned on. As a result, the lock mechanism 24 is released at the time point J, and the lid 22 can be displaced from the overstroke position to the open position.

The relay output is turned off at the time point K when the first predetermined time Ta has elapsed from the time point J, and the operation of returning the lock claw 30 to the lock position starts. In this case, the open sequence flag changes from yes to no at time G when (maximum time Tmax + first predetermined time Ta + third predetermined time Tc) elapses from time point A.

Thus, when the door lock device 55 is in the unlocked state, the responsiveness of unlocking the lid 22 is not deteriorated, and when the door lock device 55 is in the locked state, the responsiveness of unlocking the lid 22 is deteriorated. Is minimized and the security of the lid device 20 is improved.

FIG. 10 is a time chart when the door status is locked (when the door is locked) and the FOB collation is not normally completed within the specified time (maximum time Tmax) (at the time of NG determination).

At time point A in the process of displacement of the lid 22 from the closed position to the overstroke position, even if the lid switch 40 changes from off to on and FOB collation is started, at time point J where the longest time Tmax has elapsed from time point A, An NG determination is made. In this case, the relay output is not turned on and the lock mechanism 24 is not released. In this case, the open sequence flag changes from yes to no at time G, when the longest time Tmax elapses from time A.

As a result, if the user is not a legitimate user, the lid 22 will not be opened and security will be maintained.

FIG. 11 is a time chart when the lid 22 is repeatedly pushed to the overstroke position when the door status is unlocked (when the door is unlocked).

At time point A in the process of displacement of the lid 22 from the closed position to the overstroke position, the lid switch 40 changes from off to on, the relay output turns on, the lock mechanism 24 is released, and then the lid 22 repeats. Even if it is displaced to the overstroke position, if the off time of the lid switch status is a short time less than the second predetermined time Tb, the lid switch status remains on and does not change. This ensures that the lid switch status does not repeatedly change from off to on, and only once when the open sequence flag changes from no to yes, a request to start unlocking is made and the lid 22 overstrokes. The start request is not unnecessarily repeated every time the position is located. As a result, it is possible to prevent the state confirmation of the door lock device 55 and the FOB collation from being unnecessarily and repeatedly started. In this case, the open sequence flag changes from yes to no at time D when (first predetermined time Ta + third predetermined time Tc) elapses from time point A.

At time point M after time point D, the lid switch status is turned on, and if this on state is maintained for a second predetermined time Tb, then at time point N, the lid switch status is turned off, thereby After that, the unlock start request is allowed.

In this way, the lid 22 is tamper proofed.

FIG. 12 is a time chart when the lid 22 is pushed to the overstroke position during FOB verification when the door status is locked (when the door is locked).

If the lid 22 is displaced to the overstroke position from time point O to time point P during the period between time point A and time point J during FOB matching, the lid switch status will be turned on from time point O to time point Q. Since the open sequence flag keeps yes, the unlock start request is not issued, and the status confirmation of the door lock device 55 and the FOB collation are not restarted.

As a result, the relay output (on output) after the completion of FOB verification is not delayed.

FIG. 13 is a time chart when the lid 22 in the open position returns to the closed position.

When the lid 22 is displaced from the open position through the closed position to the overstroke position at the time point S when the lock claw 30 returns to the lock position, the lid 22 is latched to the closed position by the lock claw 30 at the time point T, and at the time point U. The lid switch status changes from on to off.

Each of the above operations improves the convenience of opening and closing the lid.
