Description

  The present invention relates to a power plug locking device that prevents unauthorized removal of a power plug.

  In recent years, with increasing awareness of environmental issues, for example, hybrid vehicles and electric vehicles have been widely used as vehicles with low carbon dioxide emissions. These vehicles run with the driving force of the motor by rotating the motor with the electric power of the battery. Therefore, when the battery is running for a long distance and the remaining battery level is reduced, the battery must be charged each time (see Patent Document 1).

  By the way, since battery charging is accompanied by the electrolytic reaction of a compound or ion with the battery cell which is a component of a battery, there exists the present condition that charging time takes comparatively long. Therefore, if the user leaves the vehicle while the battery is being charged, there is a possibility that the power will be stolen by a third party changing the power plug. Therefore, in a battery-chargeable vehicle, it has been studied to mount a lock device so that the power supply plug is not removed illegally when the power supply plug is connected to the vehicle.

To charge.

  As shown in FIG. 2, a lid 20 that opens and closes a power feeding port 19 of the vehicle body 18 is provided on the side wall of the vehicle body 18 so as to be able to open laterally. The power supply port 19 is provided with a storage box 21 for attaching the lid 20 and various parts around the power supply port 19.

  A substantially cylindrical inlet 22 into which the power supply plug 17 is fitted is attached and fixed at a substantial center of the storage box 21 by a plurality (four in this example) of fastening members 23. The power receiving connector 24 on the vehicle body 18 side is formed with a plurality of electrical connection terminals (power terminals, control terminals, etc.) and is drawn out from a through hole 22 a penetrating through the center of the inlet 22. The inlet 22 is provided with a plug connection detection sensor 25 shown in FIG. 1 for detecting that the power supply plug 17 is completely inserted into the power receiving connector 24. The storage box 21 corresponds to an attachment location of the apparatus main body.

  As shown in FIG. 3, the power supply plug 17 is on the power supply side of the charging system 14 and has an electrical connection terminal similar to the power receiving connector. A lock arm 27 is rotatably attached to the plug body 26 of the power supply plug 17 as a retaining member at the time of connection. The lock arm 27 can be rotated in a direction intersecting the longitudinal direction with the center in the longitudinal direction as a rotational axis 28. In the lock arm 27, a claw portion 29 at the tip and an arm operation portion 30 at the base are exposed to the outside of the plug body 26. The lock arm 27 is provided with a biasing member 31 that constantly biases the lock arm 27 toward the closing side at a position near the arm operation unit 30.

  When connecting the power supply plug 17 to the power reception connector 24, the power supply plug 17 is inserted straight toward the power reception connector 24 (in the −X axis direction in FIG. 3). At this time, when the claw portion 29 comes into contact with the locking protrusion 32 at the top of the inlet 22, the lock arm 27 is guided by the inclined surface 33 and goes up the locking protrusion 32. When the power supply plug 17 is completely inserted into the inlet 22, the lock arm 27 is rotated to the closed side by the urging force of the urging member 31. For this reason, the nail | claw part 29 is hooked on the latching protrusion 32, and the electric power supply plug 17 is prevented from coming off by the inlet 22. FIG. The locking protrusion 32 corresponds to a protrusion.

  When the hybrid system 4 confirms that the power supply plug 17 is completely inserted into the power receiving connector 24, the hybrid system 4 causes the power supply plug 17 (charging facility 15) to charge the battery 5. When the hybrid system 4 confirms that the battery 5 is fully charged, the hybrid system 4 causes the power supply plug 17 to finish charging. When the power supply plug 17 is removed from the power receiving connector 24 after the charging is finished, the arm operating portion 30 is pushed to rotate the lock arm 27 to the open side and move away from the locking protrusion 32. In this state, the power supply plug 17 is removed from the vehicle 1 by pulling it straight out from the power receiving connector 24.

  As shown in FIGS. 4 to 6, the storage box 21 in the power supply port 19 is provided with a power supply plug lock device 34 that prevents unauthorized removal of the power supply plug 17 connected to the power receiving connector 24. The power plug lock device 34 of this example performs switching from the unlocked state to the locked state by manual operation, and the switching from the locked state to the unlocked state is interlocked with the unlocking operation of the vehicle door by the wireless key system 7. Do it.

  As shown in FIG. 4, the device main body 35 of the power supply plug lock device 34 is attached and fixed to the storage box 21 by being fastened together with the inlet 22 by two upper portions 23 a and 23 a of the four fastening members 23. ing. Further, the power plug lock device 34 may be a retrofit article. In this case, the upper two fastening members 23a and 23a are removed, the apparatus main body 35 is positioned with respect to the attached inlet 22, and then the apparatus main body 35 is attached by being fastened together with the inlet 22 by the fastening members 23a and 23a. .

  As shown in FIG. 6, the case 36 of the device main body 35 is provided with a case main body portion 37 that houses various components of the power plug locking device 34 and a lid portion 38 that closes the opening of the case main body portion 37. . The lid portion 38 is integrally assembled to the case main body portion 37 by, for example, a snap fit or a bolt. The fastening members 23 a and 23 a are passed through through holes 37 a and 37 a formed at both ends of the case main body portion 37 and through holes 38 a and 38 a formed at both ends of the lid portion 38.

  A lock bar 39 for restricting the opening operation of the lock arm 27 is attached to the case 36 so as to be rotatable around an axis L1 along the apparatus depth direction (X-axis direction in FIG. 6). In the lock bar 39, a rotation shaft 40 extending in the X-axis direction of FIG. 6 at the base end portion is pivotally supported in the shaft hole 41 of the case main body portion 37. A biasing member 42 that constantly biases the lock bar 39 in the unlocking direction (the direction of arrow A <b> 2 in FIG. 6) is attached to the rotating shaft 40. As the urging member 42, for example, a torsion spring is used. A locking claw 43 that projects on the claw portion 29 of the lock arm 27 when projecting into the closed state protrudes from the distal end portion of the lock bar 39. The lock bar 39 rotates in a space 44 shown in FIG. 4 formed when the case main body portion 37 and the lid portion 38 are assembled. The lock bar 39 corresponds to a lock member.

  As shown in FIGS. 4 to 6, at the position near the rotation shaft 40 in the lock bar 39, a knob portion 45 that is operated when the lock bar 39 is rotated in the locking direction (the direction of arrow A <b> 1 in FIG. 6). Is provided. The knob portion 45 is integrally formed with the main body portion of the lock bar 39. When the lock bar 39 is rotated in the locking direction, it is operated by pushing the knob portion 45 downward. When the knob portion 45 is pushed downward and rotated in the closing direction of the lock bar 39, the lock bar 39 can be rotated in the locking direction until the knob portion 45 comes into contact with the contact surface 46 of the case main body portion 37. It is. The knob 45 corresponds to the operation unit.

  As shown in FIG. 6, the case main body portion 37 has a lock piece 47 that cooperates with the lock bar 39 to restrict the opening operation of the lock arm 27 along the device height direction (Z-axis direction in FIG. 6). It is pivotally supported so as to be rotatable around the center L2. A rotation shaft 49 extending in the apparatus height direction protrudes from a corner portion of the lock piece 47, and the rotation shaft 49 is pivotally supported by the shaft hole 50 of the case main body portion 37. A biasing member 51 that constantly biases the lock piece 47 in the lock direction (the direction of arrow B1 in FIG. 6) is attached to the rotation shaft 49. As the urging member 51, for example, a torsion spring is used. The lock piece 47 corresponds to a piece member.

  When the lock piece 47 comes into contact with the side wall of the lock bar 39 located at the unlock position and cannot be rotated in the lock direction, the lock piece 47 does not fix the lock arm 27 to the inlet 22 (see FIGS. 7 and 7). 8 state). The lock piece 47 rotates in the closing direction and rotates in the locking direction (in the direction of the arrow B1 in FIG. 6) by the urging force of the urging member 51 to hold the lock bar 39 from above. Then, the lock position for fixing the lock arm 27 to the inlet 22 (the state shown in FIGS. 9 and 10) is taken.

  The lock piece 47 is formed with a substantially plate-like lock bar abutting portion 52 that is a contact portion with the lock bar 39. When the lock piece 47 takes the lock position, the lock bar abutting portion 52 presses the lock bar 39 from above, so that the lock arm 27 is fixed by the lock bar 39. Further, when the lock piece 47 is in the unlock position, the lock bar abutment portion 52 is separated from the lock bar 39 and allows the urging member 42 of the lock bar 39 to rotate in the unlock direction. The lock piece 47 in the unlock position has the lock bar abutting portion 52 accommodated in the accommodation hole 53 formed in the case main body portion 37.

  As shown in FIG. 6, the lid portion 38 is formed with a storage hole 38b for storing the lock piece 47 in the locked position. The upper wall of the storage hole 38b is formed as a planar piece support portion 54 that supports the lock piece 47 from above. Therefore, when the lock bar 39 is in the locked state, even if an external force in the unlocking direction (opening direction) is applied to the lock arm 27, the piece support portion 54 supports the lock piece 47 from above, so that the lock bar 39 Hold the lock state. When this fraud is released, an external force applied to the lock piece 47 from the lock bar 39 is received by the piece support portion 54 and is eventually supported by the upper two fastening members 23a and 23a.

  An actuator 55 for connecting the lock piece 47 to the lock position is connected to the lock piece 47 via a wire 56. Specifically, a wire locking portion 57 is provided on the bottom surface of the lock piece 47, and a ring portion 58 at the tip of a wire 56 extending from the actuator 55 is slidably locked to the wire locking portion 57. The wire locking portion 57 is disposed at a position shifted to the front side of the drawing with respect to the rotation shaft 49 on the rotation plane (XY plane in FIG. 6) of the lock piece 47. The actuator 55 and the wire locking portion 57 constitute a releasing means, and the wire 56 constitutes a releasing means and a connecting member.

  The actuator 55 is a suction solenoid that pulls the wire 56 forward only when energized. The actuator 55 is formed separately from the device main body 35 of the power supply plug lock device 34. That is, the actuator 55 of this example is not provided at the power supply port 19 but is disposed inside the vehicle body 18. The actuator 55 is connected to the door lock motor 12 through electrical wiring in order to operate with the current flowing through the door lock motor 12.

  As shown in FIG. 5, the wire 56 is passed through a through hole 59 penetrating the case main body 37, and is drawn out to the actuator 55 through a through hole 60 formed in the side wall of the storage box 21. A seal member 61 is provided between the side wall of the storage box 21 and the case 36 to ensure waterproofness between the through holes 59 and 60. For example, an O-ring is used as the seal member 61, and the seal member 61 is attached to an attachment groove 37 b formed on the end surface of the case main body 37.

  As shown in FIG. 1, a lock detection switch 62 that is turned on when the power supply plug lock device 34 is locked is connected to the wiring connecting the door lock motor 12 and the actuator 55. As the lock detection switch 62, for example, a limit switch that is mechanically turned on when the lock bar 39 (or the lock piece 47 is acceptable) reaches the lock position is used.

  For this reason, when the power supply plug lock device 34 is in the locked state, the lock detection switch 62 is in the on state. Therefore, when a current flows through the door lock motor 12 during the unlocking operation of the vehicle door, a part of the current flows. The actuator 55 flows to the actuator 55, and the actuator 55 pulls the lock piece 47 in the unlocking direction. On the other hand, when the power plug locking device 34 is in the unlocked state, the lock detection switch 62 is in the off state. Therefore, even if a current flows through the door lock motor 12 due to the locking operation of the vehicle door, this flows into the actuator 55. The actuator 55 does not operate.

Next, the operation of the power supply plug lock device 34 of this example will be described with reference to FIGS.
As shown in FIGS. 7 and 8, when the power plug locking device 34 is in the unlocked state, the lock bar 39 is rotated in the unlocking direction (in the direction of arrow A2 in FIG. 7) by the biasing force of the biasing member 42. The lock piece 47 is laterally supported by the side surface of the locking claw 43. For this reason, even if the lock piece 47 receives the urging force of the urging member 51, the lock piece 47 does not rotate in the locking direction and is held at the unlock position. As described above, since the power supply plug locking device 34 maintains the unlocked state, the power supply plug 17 can be freely inserted into and removed from the power receiving connector 24 under this state.

  After the power plug 17 is inserted into the power receiving connector 24, in order to lock the power plug lock device 34, first, the knob 45 of the lock bar 39 is manually operated downward (in the direction of arrow A1 in FIG. 7). knock down. At this time, when the state in which the lock bar 39 horizontally supports the lock piece 47 in the process of rotating the lock bar 39 in the lock direction (the direction of the arrow A1 in FIG. 7) is eliminated, the lock piece 47 is urged. By the urging force 51, it is rotated in the locking direction (arrow B1 direction in FIG. 7).

  9 and 10, when the lock piece 47 rotates approximately 90 degrees from the unlock position and takes the lock position, the lock piece 47 holds the lock bar 39 together with the lock bar abutting portion 52 from above. It will be in a state to support. That is, the lock position of the lock bar 39 is held by the lock piece 47. As a result, the power supply plug locking device 34 is locked, so that the power supply plug 17 is fixed to the inlet 22 and unauthorized removal of the power supply plug 17 by a third party is prevented.

  The unlocked power feeding plug lock device 34 is unlocked wirelessly with the wireless key 6. By the way, since the lock detection switch 62 is turned on when the power supply plug lock device 34 is locked, a part of the current is supplied to the actuator 55 when a current flows through the door lock motor 12 when the door lock is unlocked. . Therefore, the actuator 55 operates by this electric current, pulls the wire 56, and rotates the lock piece 47 in the unlocking direction (arrow B2 direction in FIG. 9).

  When the lock piece 47 rotates approximately 90 degrees from the lock position and takes the unlock position, the state in which the lock piece 47 supports the lock bar 39 is released. For this reason, the lock bar 39 is rotated in the unlocking direction (the direction of arrow A2 in FIG. 9) by the urging force of the urging member 42. At this time, when the lock bar 39 rotates to the unlock position, the locking claw 43 reaches a position where the lock piece 47 can be laterally supported.

  For this reason, even if the current does not flow to the door lock motor 12 and the actuator 55 does not pull in the wire 56, the lock piece 47 can be supported laterally by the lock bar 39, and is thus maintained in the unlocked position. That is, even if the state where the actuator 55 pulls the wire 56 is released, the power supply plug locking device 34 is held in the unlocked state of FIGS.

  As described above, in this example, the lock piece 47 is laterally supported by the lock bar 39 positioned at the unlock position, and the lock piece 47 is maintained at the unlock position, so that the power plug lock device 34 is unlocked. Hold. Further, when the lock bar 39 is rotated in the lock direction by manual operation and the lateral support by the lock bar 39 is released, the lock piece 47 starts to rotate in the lock direction by the urging force of the urging member 51. Then, the lock piece 47 presses the lock bar 39 from above and fixes it to the lock arm 27, so that the power supply plug lock device 34 is locked. For this reason, the power supply plug lock device 34 of this example only requires the lock bar 39, the lock piece 47, the urging members 42 and 51, and the like. As a result, the number of components is reduced. Therefore, it is possible to reduce the size of the power plug lock device 34.

  Further, since the power plug lock device 34 is locked by a manual operation of pushing the knob 45 of the lock bar 39, the power plug lock device 34 is locked only when the user really wants to shift to the lock state. Can be performed. For this reason, an unnecessary locking operation is not performed, and early deterioration of components is suppressed.

  On the other hand, the unlocking of the power plug lock device 34 is interlocked with the locking operation of the vehicle door by the wireless key system 7. Therefore, if the vehicle door is locked with the wireless key 6, the power plug lock device 34 is also simultaneously unlocked. Change. Therefore, since the power feeding plug lock device 34 can be shifted to unlock simultaneously with the vehicle door, convenience during unlocking operation is ensured.

  Further, the actuator main body 35 and the actuator 55 are separated from each other by separating the actuator 55 from the apparatus main body 35 which is a mechanism part of the power supply plug lock device 34. For this reason, the apparatus body of the apparatus main body 35 can be small, and the actuator 55 can be freely arranged at a location different from the apparatus main body 35. Therefore, even if the power supply port 19 has only a limited component mounting space, the power supply plug lock device 34 can be attached to the vehicle body 18 as long as the apparatus main body 35 can be mounted there. Become.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) Since the power supply plug lock device 34 of this example only requires the lock bar 39, the lock piece 47, the biasing members 42 and 51, etc., the number of necessary parts can be reduced. Therefore, the device size of the power supply plug lock device 34 can be reduced.

(2) Since the knob portion 45 that is operated when the lock is switched is formed integrally with the lock bar 39, the effect of reducing the number of parts is enhanced.
(3) When the lock piece 47 presses the lock bar 39 from above and takes a locked state, the wire 56 is pulled by the driving force of the actuator 55, and the lock piece 47 can be rotated approximately 90 degrees in the unlocking direction. For example, the lock piece 47 is separated from the lock bar 39, and the lock bar 39 is rotated in the lock direction by the urging force of the urging member 42. Therefore, the power plug lock device 34 in the locked state can be returned to the original unlocked state without any problem.

  (4) The unlocking operation of the power supply plug locking device 34 is an electric type in which the wire 56 is pulled by the driving force of the actuator 55 to separate the lock piece 47 from the lock bar 39. For this reason, when the power supply plug lock device 34 is switched to the unlocked state, this operation is automatically executed by the actuator 55, so that convenience for switching the power supply plug lock device 34 to the unlocked state is ensured. Can do.

  (5) The actuator 55 is separated from the apparatus main body 35, and the apparatus main body 35 and the actuator 55 are separated. For this reason, the physique of the device main body 35 itself can be small, and the degree of freedom of arrangement of the actuator 55 increases. Therefore, even if the mounting space for the power supply plug lock device 34 is limited, mounting feasibility increases.

  (6) Since the unlocking operation of the power plug locking device 34 is interlocked with the unlocking operation of the vehicle door, if the vehicle door is unlocked by the wireless key system 7, the power plug locking device 34 is unlocked at the same time. Switch to state. Therefore, the power supply plug lock device 34 in the locked state can be easily switched to the unlocked state.

  (7) A seal member 61 is provided between the side wall of the storage box 21 and the case 36 to ensure waterproofness between the through holes 59 and 60. For this reason, water or the like hardly enters the vehicle body 18 or the power supply plug lock device 34 from this portion, so that the effect of preventing failure of the electrical components is enhanced.

  (8) The lock bar 39 is a member that rotates about the axis L1 extending in the apparatus depth direction, and the lock piece 47 is a member that rotates about the axis L2 extending in the apparatus height direction. Therefore, with a simple configuration, the lock piece 47 is held in the unlock position by the lock bar 39 in the unlock position, or the lock bar 39 is held in the lock position by the lock piece 47 moved to the lock position. can do.

  (9) The lid 38 is provided with a lock bar abutting portion 52 that is supported from above when the lock bar 39 takes the locked position. Therefore, when the power plug locking device 34 is in the locked state, even if a third party forcibly operates the lock arm 27 in the opening direction, the lock piece 47 that is about to be lifted by this external force is removed from the lock bar abutting portion.
