Description

The present invention relates to a vehicle lid lock device that can be applied to a charging port lid, a fuel lid, and the like.

Conventionally, as a vehicle lid lock device, for example, there is a device that holds a lid (lid body) in a closed state and opens the lid due to pushing of the lid (see Patent Document 1). This vehicle lid lock device includes a housing provided on the vehicle body, a latch position that is rotatably supported by the housing and that engages with a striker to hold the lid in a closed position, and a latch position that displaces the lid to an open position. A latch that can be displaced between the unlatched position where it disengages with the striker and the detection position where it is pushed by the lid and further rotates from the latched position to the pushed position (for example, a latch with an inclined engagement surface). a fork having a fork), a biasing means (a first torsion coil spring) that biases the latch toward the unlatched position, a blocking position that prohibits the latch from displacing from the latched position to the unlatched position, and a biasing means (a first torsion coil spring) that biases the latch toward the unlatched position; and a pole displaceable between unblocked positions that permits displacement to an unlatched position.
In this vehicle lid lock device, when the lid is manually closed, the striker contacts the latch at the unlatched position and presses the latch. This pressing causes the latch to rotate to the latched position against the urging force of the urging means. In response to this, the pawl is displaced to the blocking position, and rotation of the latch is restricted with the latch engaged with the striker. This holds the lid in the closed position. On the other hand, when the lid is pushed from the closed state to the push-in position, the latch is pushed by the striker and reaches the detection position. Thereafter, the pawl is displaced to the unblocked position, whereby the latch pushes out the striker due to the urging force of the urging means, and the lid is opened via the striker.
According to this vehicle lid lock device, manufacturing costs can be reduced.

The shaft-like member 5 has a top surface 55 and a bottom surface 56 that are perpendicular to the rotation axis, and a side surface 52 that is parallel to the rotation axis direction. Further, the shaft-like member 5 includes a circular groove-shaped torsion spring accommodating portion 57 provided on the upper surface 55 for accommodating the torsion spring 6, and a torsion spring accommodating portion 57 provided so as to protrude from the upper surface 55 in the direction of the rotation axis. It has a latch fixing part 51 that fixes the switch 10, and a switch pressing part (not shown) that is provided on the side surface part 52 and that presses the button part of the switch 10. The heart cam 54 is recessed in the side surface 52 of the shaft-like member 5.

The lock pin 7 is a rod-like member shaped into a substantially U-shape, and has a base end 72, a tip end 71, and an intermediate part 74. The distal end portion 71 engages with the heart cam 54 on the shaft member 5, and the proximal end portion 72 is attached to the housing 4 so as to be movable forward and backward and rotatable. As a result, the lock pin 7 has a distal end 71 that can move along the heart cam 54 in the direction of the rotational axis of the shaft-like member 5, and a distal end 71 that can move in the direction perpendicular to the rotational axis of the shaft-like member 5 (the shaft-like member 5).

The leaf spring 13 is disposed so as to face the side surface 52 of the shaft-like member 5, and urges the lock pin 7 toward the groove bottom side of the heart cam 54. As a result, the tip 71 of the lock pin 7 is always pressed against the heart cam 54.

The latch 3 includes a fixed shaft portion 31 that extends in the direction of the swing axis of the latch 3 and is fixed by a latch fixing portion 51 of the shaft member 5 and a screw 35, and a fixed shaft portion 31 that is connected to the fixed shaft portion 31 and is connected to the swing axis of the latch 3. A first claw portion 32 extending in a direction away from the swing axis on a plane orthogonal to the axis, and a first claw portion 32 connected to the fixed shaft portion 31 and extending in the same plane as the first claw portion 32. It has a second claw part 33 that is positioned apart from the second claw part 33 and extends so as to face the first claw part 32 in the swinging direction of the latch 3. The first claw portion 32 is a holding portion that restricts the striker 21 from moving rearward in the advancing direction when the latch 3 is in the lock position. On the other hand, the second claw portion 33 is a push-out portion that pushes the striker 21 backward in the traveling direction as the latch 3 swings. The striker 21 is composed of a cylindrical engaging portion 211 and a pair of arm portions 212 that support the engaging portion 211 on both sides, and includes a first claw portion 32 and a second claw portion. 33 is disposed parallel to and spaced from the surface of the protruding portion 45, and is configured to contact and engage with the engaging portion 211.

In this embodiment, the latch 3, the shaft member 5, the lock gear 8, and the release lever 12 are arranged so that their rotation axes (swing axes) are coaxial. The release lever 12 and the lock gear 8 can swing together, and the latch 3 and the shaft member 5 can swing together. That is, the latch 3 is swingably attached to the housing 4 via the shaft member 5.

The torsion spring 6 is housed in the torsion spring accommodating portion 57, and has one end locked to the shaft member 5 and the other end locked to the second housing 42. Thereby, the torsion spring 6 biases the shaft member 5 to rotate. The torsion spring 6 swings and urges the latch 3 toward the unlocked position via the shaft member 5, and provides the latch 3 with swinging force for pushing out the striker 21 by the second claw portion 33. plays a role.

As shown in FIG. 6, the heart cam 54 has a first position 540a where the tip 71 of the lock pin 7 is located when the latch 3 is in the unlock position, and a first position 540a where the tip 71 of the lock pin 7 is located when the latch 3 is in the lock position. The first position 540a and the second position 540b are provided at different positions in the rotational direction of the shaft-like member 5. Further, the heart cam 54 is connected to a first path 545 along which the tip 71 of the lock pin 7 is guided when the latch 3 swings from the unlocked position to the locked position, and between the first path 545 and the second position 540b. a first push-in position 546 located at and a second push-in position 547 located between. That is, in the heart cam 54, a first position 540a, a first path 545, a first push-in position 546, a second position 540b, a second push-in position 547, and a second path 548 are connected in an annular manner. It is approximately heart-shaped.

Further, the heart cam 54 is configured such that the first push-in position 546 becomes deeper with respect to the first route 545 in the direction approaching the rotation axis of the shaft-like member 5 between the first path 545 and the first push-in position 546. between the first step 541 and the first pushed-in position 546 and the second position 540b, the second position 540b becomes deeper with respect to the first pushed-in position 546 toward the rotation axis of the shaft-like member 5. Between the second step 542, the second position 540b, and the second pushed-in position 547, the second pushed-in position 547 becomes deeper in the direction approaching the rotation axis of the shaft-like member 5 with respect to the second position 540b. Between the second path 548 and the first position 540a, the first position 540a becomes deeper with respect to the second path 548 in the direction approaching the rotation axis of the shaft-like member 5. It has a fourth step 544.

Further, the first path 545 is inclined to become shallower in the direction away from the rotation axis of the shaft-like member 5 as it goes from the first position 540a direction to the first step 541 direction, and the second path 548 is inclined to become shallower in the direction away from the rotation axis of the shaft-like member 5. It is inclined so that it becomes shallower in the direction away from the rotation axis of the shaft-like member 5 as it goes from the direction 547 toward the first position 540a.

As shown in FIG. 3, the lock gear 8 has a main body 83 provided at a position facing the bottom surface 56 of the shaft-like member 5, and a surface of the main body 83 opposite to the bottom surface 56 of the shaft-like member 5. A release lever fixing part 82 provided on the side and protruding from a surface orthogonal to the rotation axis of the lock gear 8 engages with a worm 91 connected to the output shaft of the motor 9 and lock gear 8 in the main body part 83. an arcuate gear portion 81 connected to a surface not orthogonal to the rotational axis of the shaft-like member 5; and a restraining portion 84 extending from the gear portion 81 along the side surface portion 52 of the shaft-like member 5 and covering a part of the heart cam 54. have.

The lock gear 8 is arranged so as to be able to swing coaxially with the swing axis of the latch 3, and is arranged to be able to swing between a non-restricted position and a restricted position. Then, when the motor 9 is driven, the lock gear 8 is swung from the non-restricted position to the restricted position by the worm 91 and the gear portion 81. As a result, the restraining portion 84 provided on the lock gear 8 covers a portion of the heart cam 54, thereby preventing the distal end portion 71 of the lock pin 7 from escaping from the second position 540b. Thereby, it is possible to restrict the lid L from moving from the closed state to the open state. Note that the driving of the motor 9 (restriction of movement of the lid L by the lock gear 8) may be configured to be linked with the locking of the door lock, or may be configured to be performed by a separate operation button provided on the remote control key. .

Next, the striker guide 11 will be explained with reference to FIGS. 1(a) and 4. As shown in FIGS. 1A and 4, the striker guide 11 is integrally molded with the first housing 41 on the surface of the protrusion 45 of the first housing 41, and has a surface facing the lower side of the movement range A of the striker 21. A first guide member 111 (first regulating member) disposed as a guide member 111 (first regulating member), a second guide member 112 (second regulating member) disposed facing the upper side of the movement range A of the striker 21, and a stopper 113 disposed facing the right side of the movement range A. That is, the striker guide 11 is disposed to surround the movement range A of the striker 21 as a whole, and restricts the movement of the striker 21 within the movement range A.

The first guide member 111 is a plate-shaped member extending along the lower side of the movement range A of the striker 21. That is, the first guide member 111 restricts the striker 21 from moving to the right in the advancing direction due to the force acting on the striker 21 from the latch 3, and the first guide member 111 restricts the movement path R of the striker 21 (the movement range A of the striker 21). It is arranged along the right side in the above-mentioned direction of travel. In other words, the upper surface of the first guide member 111 serves as a sliding surface on which the striker 21 comes into contact and slides when the striker 21 attempts to move to the right in the advancing direction. Although the details will be described later, for example, when the lid L is pushed in during the opening operation of the lid L, the striker 21 tries to move to the right in the traveling direction (see FIG. 7(b)), but the first guide member 111 Restricts movement to the right in the direction of travel.
Further, considering the vertical direction, it can be said that the first guide member 111 extends along the lower side in the vertical direction of the lateral side in the traveling direction of the movement range A of the striker 21. As a result, the upper surface of the first guide member 111 is inclined downward toward the advancing direction of the striker 21 when considering the vertical direction (see FIG. 5(a)).

On the other hand, the second guide member 112 is composed of a plate-like member extending along the upper side of the movement range A of the striker 21. That is, the second guide member 112 restricts the striker 21 from moving to the left in the advancing direction due to the force acting on the striker 21 from the latch 3, and prevents the striker 21 from moving to the left side in the moving direction R (the moving range A of the striker 21). It is arranged along the left side of the above-mentioned direction of travel. That is, the lower surface of the second guide member 112 is a sliding surface on which the striker 21 comes into contact and slides when the striker 21 attempts to move to the left in the advancing direction. Although the details will be described later, for example, when the striker 21 starts contacting the latch 3 during the closing operation of the lid L, the striker 21 tries to move to the left in the advancing direction (see FIG. 6(a)), but the second guide member 112 restricts movement to the left in the traveling direction.
Further, considering the vertical direction, it can be said that the second guide member 112 extends along the upper side in the vertical direction of the lateral side in the traveling direction of the movement range A of the striker 21. Note that the second guide member 112 is formed with a cutout portion 112b so as not to interfere with the fixed shaft portion 31 of the latch 3, and the second guide member 112 is It is divided into parts.

Furthermore, chamfered portions 111a and 112a are formed at the inner corners of the left ends (the rear ends in the traveling direction) of the first guide member 111 and the second guide member 112. These chamfered portions 111a and 112a function as guiding slopes that guide the striker 21 into the striker guide 11. That is, the left end portions (base end portions) of the first guide member 111 and the second guide member 112 also function as an introduction port for guiding the striker 21 into the striker guide 11 by the chamfered portions 111a and 112a.

The stopper 113 is disposed facing the right side of the movement range A of the striker 21 and is composed of a plate-shaped member extending in the advancing direction of the striker 21 . That is, the stopper 113 restricts the striker 21 from moving in the traveling direction beyond the moving range A, and receives the force when the lid L is pushed in, and is used to prevent the striker 21 from moving in the traveling direction beyond the moving range A. It is placed facing the side.

Further, the stopper 113 is disposed between the first guide member 111 and the second guide member 112 with a predetermined interval G therebetween. In this embodiment, this interval G functions as a discharge port for discharging water within the striker guide 11 (water drainage structure). As shown in FIG. 5(a), the water that has entered the striker guide 11 flows along the upper surface of the first guide member 111 and reaches around the stopper 113, and from the distance G between the first guide member 111 and the stopper 113. It is discharged outside the striker guide 11. Note that by forming a gap G not only with the first guide member 111 but also with the second guide member 112, the distance G shown in FIG. As shown in FIG. 2, even when the vehicle lid lock device 1 is installed upside down, the water that has entered the striker guide 11 is discharged to the outside of the striker guide 11.

Note that the heights (heights in the front-rear direction) of the first guide member 111, the second guide member 112, and the stopper 113 are set to heights that do not interfere with the latch 3. Therefore, the first guide member 111, the second guide member 112, and the stopper 113 are configured to mainly contact the arm portion 212 of the striker 21 rather than the engagement portion 211 of the striker 21 to restrict movement of the striker 21. It has become. That is, it can be said that the first guide member 111, the second guide member 112, and the stopper 113 are arranged in the interval (empty space) created for the latch 3 to come into contact with the engagement portion 211 of the striker 21. Note that the heights of the first guide member 111, the second guide member 112, and the stopper 113 are set in consideration of the movement of the striker 21 in a circular orbit about the hinge. That is, when opening and closing the lid L, the striker 21 moves in a circular orbit around the hinge of the lid L, so the striker 21 is configured to move (pitch) slightly in the longitudinal direction on the vehicle lid lock device 1. However, the heights of the first guide member 111, the second guide member 112, and the stopper 113 are such that even if there is this movement in the front-rear direction, they are in reliable contact with the arm portion 212 of the striker 21, and the movement of the striker 21 is ensured. It is set at a height that can be regulated.

(Operation of vehicle lid lock device)
Next, the closing operation and opening operation of the lid L using the vehicle lid lock device 1 will be described with reference to FIGS. 6 and 7. First, with reference to FIG. 6, the closing operation of the lid L using the vehicle lid lock device 1 will be described. In this closing operation, when the user closes the lid L, the vehicle lid lock device 1 is activated and the lid L is locked in the closed state.

As shown in FIG. 6(a), when the user closes the lid L in the open state, the striker 21 contacts the second claw portion 33 of the latch 3 in the unlocked position, and locks the latch 3. Press. At this time, the striker 21 comes into contact with the inclined surface of the second claw part 33, and a component of the force acting on the striker 21 from the second claw part 33 acts on the left side in the direction of movement of the striker 21. Although the striker 21 tries to move to the left in the direction of travel, the second guide member 112 restricts the movement to the left in the direction of travel.

As the lid L is further closed, the latch 3 swings from the unlocked position due to the pressure of the striker 21 against the urging force of the torsion spring 6, and the shaft member 5 to which the latch 3 is fixed rotates. To go. Along with this, the tip portion 71 of the lock pin 7 moves on the first path 545 from the first position 540a. Then, as shown in FIG. 6(b), when the lid L is further closed and the latch 3 passes through the lock position and reaches the push-in position, the tip 71 of the lock pin 7 passes through the first step 541 and reaches the first push-in position. 546, and the striker 21 hits the stopper 113 again. At this time, the striker 21 hits the stopper 113 before the tip 71 of the lock pin 7 hits the end of the first push-in position 546, so the stopper 113 receives the force when closing the lid L. Also, at this time, the striker 21 comes into contact with the inclined surface of the second claw part 33, and a component of the force acting on the striker 21 from the second claw part 33 acts on the right side in the advancing direction of the striker 21. Although the striker 21 attempts to move to the right in the direction of travel, the first guide member 111 restricts the movement to the right in the direction of travel.

Thereafter, when the user releases the lid L, the shaft member 5 rotates due to the biasing force of the torsion spring 6. As a result, as shown in FIG. 6(c), the latch 3 swings from the push-in position to the lock position, and the tip 71 of the lock pin 7 reaches the second position 540b via the second step 542. When the tip 71 of the lock pin 7 reaches the second position 540b, the tip 71 of the lock pin 7 abuts against the inner wall of the heart cam 54 at the second position 540b. This restricts the rotation of the shaft-like member 5. As a result, the swinging of the latch 3 is restricted and the latch 3 is maintained at the locked position, so that the lid L is locked (held) in the closed state via the striker 21.

Next, with reference to FIG. 7, the opening operation of the lid L using the vehicle lid lock device 1 will be described. In this opening operation, the vehicle lid lock device 1 is activated to open the lid L due to the user pushing the lid L. As shown in FIG. 7(a), the main closing operation is performed from a state in which the latch 3 is located at the lock position and the lid L is held in the closed state.

As shown in FIG. 7(b), when the user pushes in the lid L, the latch 3 swings from the lock position to the push-in position due to the pressure of the striker 21 against the urging force of the torsion spring 6. The shaft-like member 5 rotates. As a result, the tip 71 of the lock pin 7 passes through the third step 543 and reaches the second push-in position 547, and the striker 21 abuts against the stopper 113. At this time, the striker 21 hits the stopper 113 before the tip 71 of the lock pin 7 hits the end of the second push-in position 547, so the stopper 113 receives the force when pushing the lid L. Also, at this time, the striker 21 comes into contact with the inclined surface of the second claw part 33, and a component of the force acting on the striker 21 from the second claw part 33 acts on the right side in the advancing direction of the striker 21. Although the striker 21 attempts to move to the right in the direction of travel, the first guide member 111 restricts the movement to the right in the direction of travel.

Thereafter, when the user releases the lid L, the shaft member 5 rotates due to the biasing force of the torsion spring 6. As a result, as shown in FIG. 7(c), the latch 3 swings from the push-in position to the unlock position, and the tip 71 of the lock pin 7 passes through the second path 548 and the fourth step 544 to the first position. 540a is reached. At this time, the swinging latch 3 pushes the striker 21 backward in the traveling direction, and the lid L is pushed open outward via the striker 21. This causes the lid L to be in an open state. Note that in the first half of this process, the component of the force acting on the striker 21 from the second claw portion 33 acts on the right side in the direction of movement of the striker 21, so that the striker 21 tries to move to the right side in the direction of movement. , the movement to the right in the traveling direction is regulated by the first guide member 111. On the other hand, in the latter half of this process, the component of the force acting on the striker 21 from the second claw portion 33 acts on the left side in the direction of movement of the striker 21, so that the striker 21 tries to move to the left side in the direction of movement. , the movement to the left in the traveling direction is regulated by the second guide member 112.

(Actions and effects of embodiments)
As described above, according to the configuration of the above embodiment, the striker guide 11 is provided with the discharge port (interval G) for discharging the water inside the striker guide 11, so that the water inside the striker guide 11 is discharged outside the striker guide 11. Can be discharged. Thereby, water that has entered the charging port 2 can be prevented from accumulating in the striker guide 11. Then, by discharging the water in the striker guide 11 from the discharge port, foreign matter such as dirt and dust that has entered the striker guide 11 can be flushed out of the striker guide 11 by the discharged water. Thereby, it is possible to suppress foreign matter from accumulating inside the striker guide 11.
That is, in order to charge the electric vehicle at the charging port 2, the lid L is opened, the charging connector is connected, and the battery is left in this state for a long time (in some cases, overnight). Therefore, foreign matter such as dirt and dust, and water such as rainwater are likely to enter the charging port 2. On the other hand, in a vehicle lid lock device 1 that employs a striker guide 11 having a first guide member 111, a second guide member 112, and a stopper 113, the striker guide 11 is provided so as to surround the movement range A of the striker 21. As a result, foreign matter that has entered the charging port 2 tends to accumulate in the striker guide 11, and water that has entered the charging port 2 tends to accumulate in the striker guide 11. These problems cause foreign matter to accumulate in the striker guide 11 and water to accumulate in the striker guide 11. As a result, if the water accumulated in the striker guide 11 freezes or foreign matter accumulates in the striker guide 11, the advance of the striker 21 is inhibited and the lid L cannot be opened or closed. Specifically, due to the obstruction of the advance of the striker 21, the lid L cannot be pushed to the pushed-in position, and the opening and closing operations of the lid L using the vehicle lid lock device 1 cannot be performed normally.
On the other hand, according to the configuration of the above embodiment, the striker guide 11 is provided with a discharge port for discharging the water inside the striker guide 11, so that foreign matter accumulates inside the striker guide 11 as described above. This can prevent water from accumulating in the striker guide 11. Thereby, it is possible to prevent a problem that the lid L cannot be opened or closed.

Further, by providing the discharge port (distance G) in the corner portion, it is possible to further suppress the accumulation of water and foreign matter. In particular, a discharge port (space G) is provided facing the corner formed by the first guide member 111 and the stopper 113, the surface of the first housing 41, and the corner formed by the first guide member 111 and the stopper 113. This makes it possible to prevent water and foreign matter from accumulating in the corner.

Furthermore, the stopper 113 is configured of a plate-like member that extends in the advancing direction of the striker 21 and forms a gap G between it and the first guide member 111, which forms the discharge port. It is possible to have a simple structure that is easy to mold, and the rigidity of the stopper 113 can be improved. Furthermore, by forming the gap G that forms the discharge port not only with the first guide member 111 but also with the second guide member 112, the vehicle lid lock device 1 can be placed in an upside-down position. Even when it is installed, sufficient water drainage capacity can be obtained. That is, depending on whether the charging port 2 to be installed is installed on the left or right side of the vehicle, the vehicle lid lock device 1 can be installed in the traveling direction of the striker 21, as shown in FIG. 5(b). Although it can be installed in an upside-down position while maintaining the fact that it is tilted vertically downward, sufficient water drainage capacity can be obtained even when installed in this position.

Further, by providing the first guide member 111 and the second guide member 112, it is possible to restrict the striker 21 from moving laterally in the advancing direction. Thereby, it is possible to suppress sideways slipping of the striker 21, and it is also possible to suppress sideways slipping of the lid L. This makes it possible to prevent the lid L from coming into contact with the body panel or the like when the lid L is opened or closed. Further, by suppressing the sideways slipping of the striker 21, the movement trajectory of the striker 21 does not become an abnormal trajectory, and the ups and downs of resistance that occur when pressing the lid L to close it do not become uncomfortable. Therefore, it is possible to prevent the user from feeling uncomfortable when operating the lid L.

Further, by providing the stopper 113, the stopper 113 can receive the force when the lid L is closed or pushed in. Therefore, parts around the latch 3 (particularly the shaft of the shaft member 5) can be prevented from being damaged by the force when the lid L is closed or pushed in.
