Description

Lock device for vehicle door

The present invention relates to a vehicle door locking device for locking a door that opens and closes an opening formed in a vehicle body, and in particular, performs a preliminary operation (for example, an operation on a key cylinder) before operating a handle provided on the door or the like. The present invention relates to a lock device that enables a lock release operation by a handle only when it is performed.

Patent Document 1 discloses a conventional example of this type of locking device.
A striker projects from the rear opening of the vehicle body of Patent Document 1, and a lock device that engages and disengages the striker is provided at the back door that opens and closes the rear opening.
This locking device includes a case fixed to the back door, a hook (latch) and a pole (ratchet) that are rotatably housed in the case, and a lock release lever and an open lever that are supported coaxially with the case. And a cancel lever and a slider slidably supported by the open lever.
The hook can rotate between an unlock position that is not engaged with the striker and a lock position that engages with the striker when the back door is in the closed position, and is urged to rotate toward the unlock position. Yes. On the other hand, the pole (latch) can rotate between an engagement position that engages with a hook positioned at a lock position and a non-engagement position that releases engagement with the hook, and rotates to the engagement position side. It is energized.

The lock release lever is linked to an outside handle provided on the back door. When the outside handle is located at the initial position (non-operating position), the lock release lever is located at the lock permissible position, and when the outside handle is rotated (unlock operation), the lock release lever rotates to the lock release position.
The open lever can rotate between the lock holding position and the lock release position, and is urged to rotate toward the lock holding position by the urging means. When the lever is in the lock holding position, the open lever cannot be engaged with the pawl. When the open lever rotates to the unlocking position, the open lever engages with the pawl and rotates the pawl to the non-engagement position.
The slider is slidable between the engageable position and the retracted position with respect to the open lever. The slider can be engaged with the lock release lever when positioned at the engageable position, and the slider cannot be engaged with the lock release lever when positioned at the retracted position.
The cancel lever can rotate between the unlocking impossible position and the unlocking possible position. The cancel lever is linked to the key cylinder provided on the back door. When the key cylinder is in the locked state, the cancel lever is located in the unlockable position, and when the key cylinder is in the unlocked state, the cancel lever can be unlocked. Located in position. Furthermore, when the cancel lever is positioned at the unlocking disabled position (when the key cylinder is in the locked state), the slider is positioned at the retracted position, and when the cancel lever is positioned at the unlockable position (when the key cylinder is in the unlocked state). The slider is in the engageable position.

When the back door that opens the rear opening of the vehicle body is closed, the striker engages with the hook and rotates the hook to the lock position side. When the hook rotates to the lock position, the pole rotates to the engagement position and holds the hook in the lock position, so that the back door is held in the closed state.
When opening the back door thus locked, the slider is first moved to the engageable position by unlocking the key cylinder. Then, by rotating the outside handle, the lock release lever is rotated to the lock release position side. Then, the lock release lever is engaged with the slider, and the open lever is rotated to the lock release position via the slider, so that the pole is rotated to the non-engagement position. As a result, the hook can rotate to the unlock position side, so that the back door can rotate in the opening direction.

On the other hand, if the key cylinder is not unlocked when the back door is locked (if it is left locked), the back door remains unrotatable in the opening direction even if the outside handle is rotated. Become. That is, in this case, since the slider remains in the disengaged position, even if the unlocking lever is rotated to the unlocking position side by rotating the outside handle, the unlocking lever cannot press the slider (shake idle). . As a result, since the open lever remains in the lock holding position, the pole remains in the engagement position and continues to hold the hook in the lock position.

JP 2006-225898 A

The lock device of Patent Document 1 requires four members, that is, a lock release lever, an open lever, a cancel lever, and a slider in addition to a hook and a pole.
Therefore, there are disadvantages that the number of parts is large and the entire apparatus is easily increased in size.

The present invention is a vehicle door that has a structure that enables a lock releasing operation by a handle only when a preliminary operation is performed before operating a handle provided on a door or the like, and can be downsized with a small number of parts. A locking device is provided.

The vehicle door locking device of the present invention is a locking device provided on the other side that can be engaged with and disengaged from a striker fixed to one of the peripheral edge of the opening formed in the vehicle body and the door that opens and closes the opening. A hook that engages with the striker and holds the closed state of the door, and an unlock position that releases the engagement with the striker, and a hook biased toward the unlock position; A pole that is rotatable between an engagement position that engages with the hook and holds the hook in the locked position and a non-engagement position that does not engage with the hook and is biased toward the engagement position; A non-contact unlocking lever that rotates between the lock holding position and the unlocking position according to the operation of the handle member, and the non-operation that does not press the pole regardless of the position of the unlocking lever location and A slidable open lever that is supported by the unlocking lever so as to be slidable between an operating position that presses the pole to the non-engaging position when the unlocking lever moves to the unlocking position, and a cancel lever A cancel lever that moves to a cancel position that positions the slide-type open lever in the non-operating position and a cancel release position that positions the slide-type open lever in the active position according to an operation means. It is characterized by.

The cancel lever may be directly linked to the slide type open lever.

A support member that rotatably supports the cancel lever is fixed to the other member, and the cancel lever can be positioned between the support member and the cancel lever at two positions, the cancel position and the cancel release position. A click stop mechanism may be provided.
In this case, the click stop mechanism includes two engagement recesses provided on the support member, one engagement protrusion provided on the cancel lever, which can be engaged with and disengaged from the engagement recess, and the engagement protrusion. An elastically deformable portion that can be elastically deformed in an engagement / disengagement direction of the portion with respect to the engaging concave portion, and a convex portion supporting portion that is supported by the elastic deformable portion and supports the engaging convex portion.

The cancel lever operating means may include a motor, and the support member may be a housing that houses the motor.

According to the present invention, only when the cancel lever is rotated to the cancel release position in advance by the cancel lever operating means, the subsequent unlock operation by the handle member is effective. That is, if the cancel lever is rotated to the cancel release position in advance, the slide type open lever moves to the operating position, and if the lock release lever is subsequently moved to the lock release position, the slide type open lever disengages the pole. The hook can be rotated to the unlock position side by pressing to the position. On the other hand, when the cancel lever is not rotated to the cancel release position in advance, the slide type open lever is positioned at the non-operating position. Therefore, even if the lock release lever is subsequently moved to the lock release position, the slide type open lever ( And the unlocking lever) does not touch the pole. Therefore, the pole remains in the engaged position and keeps the hook in the locked position.
In addition, since there are only three components of the lock device other than the hook and the pole, that is, the lock release lever, the slide type open lever, and the cancel lever, the number of parts is smaller than that of the conventional lock device.
Furthermore, since the number of parts is reduced, the entire locking device can be reduced in size as compared with the prior art.

According to the second aspect of the present invention, the number of parts is reduced as compared with the case where another member is interposed between the cancel lever and the slide type open lever, and the cancel lever is changed to the slide type open lever. The power transmission becomes more reliable.

When configured as in the invention described in claim 3, it is possible to reliably position the cancel lever at two positions of the cancel position and the cancel release position with a simple configuration.

When configured as in the invention described in claim 4, a reliable click stop operation can be realized with a simple configuration.

According to the invention described in claim 5, the cancel lever can be operated using power. Furthermore, since a part of the housing for housing the motor is used as a click stop mechanism, the number of parts can be reduced as compared with the case where the engaging recess is formed in a support member different from the housing.

Further, a torsion spring 72 is rotatably attached to the rivet 71, one end of the torsion spring 72 is locked to the lock release lever 59, and the other end of the torsion spring 72 is locked to the lever support portion 52. The torsion spring 72 urges the lock release lever 59 to rotate toward the lock holding position, and when no external force other than the torsion spring 72 is applied to the lock release lever 59 (the outside handle 13 is in the initial position (non-operating position). ), The lock release lever 59 is positioned at the lock holding position when the locking contact piece 66 contacts the locking stopper piece 58b. On the other hand, when the outside handle 13 is rotated to the operation position, this force is transmitted to the lock release lever 59 via the operation wire, and the lock release lever 59 reaches the lock release position against the rotational biasing force of the torsion spring 72. When the lock is released, the contact piece 69 at the time of unlocking comes into contact with the stopper piece 58a at the time of unlocking, so that the rotation is restricted at the unlock position.

A slide type open lever 74 is slidably attached to the lock release lever 59.
The slide-type open lever 74 is an integrally molded product made of a synthetic resin, and a central concave portion 75 is formed in the central portion of the front surface that is recessed rearward by one step compared to the upper and lower end portions. In the vicinity of the right end of the lower end portion of the slide type open lever 74, a slide support hole 76 penetrating in the vertical direction (longitudinal direction of the slide type open lever 74) is formed (see FIGS. 3 to 6). A pair of left and right sliding contact pieces 77 project from the upper part of the slide type open lever 74. Further, a pressed protrusion 78 projects rearwardly at a substantially central portion of the rear surface of the slide type open lever 74.
As shown in FIGS. 3 to 6, the slide type open lever 74 is attached to the lock release lever 59 so as to be relatively slidable in the longitudinal direction of the slide type open lever 74. More specifically, the central recess 75 is positioned immediately after the main body 60, the fitting insertion piece 62 is slidably fitted into the slide support hole 76, and both the front and rear surfaces of the left and right sliding contact pieces 77 are disposed on the main body. The rear surface of 60 and the front surfaces of the left and right support protrusions 65 are slidably brought into contact with each other. The slide-type open lever 74 is slidable with respect to the lock release lever 59 between the operating position shown in FIGS. 3 and 4 and the non-operating position shown in FIGS. 5 and 6 (positioned at any position). In some cases, a part of the insertion piece 62 is fitted into the slide support hole 76, and at least a part of the front and rear surfaces of the left and right sliding contact pieces 77 is provided on the rear surface of the main body 60 and the front surfaces of the left and right support protrusions 65. Contact).

Next, the configuration of the actuator unit 80 will be described. The actuator unit 80 is a unit that is substantially orthogonal to the lock unit 25 and extends substantially in the vertical direction when the back door 12 is located at the fully closed position.
The actuator unit 80 includes a rear case (housing) (supporting member) 81 made of synthetic resin. A housing recess 82 is formed on the front surface of the rear case 81. In the housing recess 82, a motor (cancel lever operating means) 83 and a worm wheel (cancel lever operating means) 87 are housed. The motor 83 is (electrically) connected to the signal receiver 14 via a control circuit, and the control circuit is (electrically) connected to a power source (not shown). An output shaft 84 that linearly extends toward the lower left and rotates about its axis projects from an end surface on the lower left side of the motor 83, and a worm 85 is integrally formed on the peripheral surface of the output shaft 84. It is. The worm wheel 87 made of synthetic resin can rotate about its own central axis with respect to the rear case 81 (storage recess 82), and teeth (not shown) formed on the peripheral surface of the worm wheel 87 mesh with the worm 85. is doing. A prismatic key projection 88 is integrally projected on the front surface of the worm wheel 87, and a female screw hole 89 is formed on the front end surface of the key projection 88.

The front surface of the rear case 81 is covered with a synthetic resin front cover (housing) (support member) 90 whose front shape is substantially the same as that of the rear case 81, and the front cover 90 is not shown. Is fixed to the rear case 81. A circular through hole 91 is formed in the front cover 90, and a front end portion of the key protrusion 88 passes forward through the circular through hole 91 and protrudes forward of the front cover 90. An arc-shaped protrusion 93 projects forward from the left end of the front surface of the front cover 90. A first engagement recess 94 and a second engagement recess 95, both of which are substantially conical, are provided in parallel on the front surface of the arc-shaped protrusion 93. Further, a female screw hole 96 and a non-rotating protrusion 97 are provided on the right side portion of the front surface of the front cover 90.

In front of the circular through hole 91 of the front cover 90, a cancel lever 99, which is an integrally molded product made of synthetic resin, is located.
The cancel lever 99 has a substantially cylindrical base 100. A front concave portion 101 is formed in the front surface of the base portion 100, and a circular communication hole 102 is formed in the bottom portion of the front concave portion 101. A rectangular recess 103 communicating with the communication hole 102 is provided on the rear surface of the base 100. The cancel lever 99 includes a pressing portion 104 protruding from the base portion 100, and a long hole 105 is formed in the pressing portion 104. Further, the cancel lever 99 is connected to a pair of elastic deformation portions 106 protruding from the base portion 100 toward the opposite side of the pressing portion 104 (radial direction of the base portion 100 in a front view), and a cross-sectional view connecting the tip portions of the elastic deformation portions 106. A W-shaped convex support portion 107 and a substantially conical engagement convex portion 108 projecting from the rear surface of the central portion of the convex portion support portion 107 are provided. Since the pair of elastic deformation portions 106 are thin, when an external force is applied to the front end portion in the front-rear direction, the pair is elastically deformed in the front-rear direction around the base end portion. On the other hand, the convex portion support portion 107 is thicker than the elastic deformation portion 106 and has a W-shaped cross section (a shape having a bead), and therefore has a high mechanical strength.
The cancel lever 99 is formed by fitting the front end portion of the key projection 88 into the square recess 103 and inserting the screw 109 inserted into the front recess 101 from the front and passing through the communication hole 102 into the female screw hole 89. The key projection 88 is fixed.

When a lock signal (wireless signal) is sent from the wireless remote controller to the signal receiving unit 14, the motor 83 (worm 85) and worm wheel 87 that receive power from the power source rotate forward, and the cancel lever 99 is shown in FIGS. 6 is located at the cancel position. When the cancel lever 99 rotates to the cancel position, the engagement convex portion 108 engages with the first engagement concave portion 94 (see FIG. 11), so that the cancel lever 99 is held at the cancel position even if the motor 83 stops thereafter. Is done. When an unlocking permission signal (radio signal) is sent from the wireless remote controller to the signal receiving unit 14, the motor 83 (worm 85) and the worm wheel 87 that receive power from the power source are reversed, and the cancel lever 99 is moved as shown in FIG. It moves to the cancel release position shown in FIG. When the cancel lever 99 rotates to the cancel release position, the engagement convex portion 108 engages with the second engagement concave portion 95 (not shown), so that even if the motor 83 stops thereafter, the cancel lever 99 is moved to the cancel release position. Retained. Further, if the cancel lever 99 rotates while the engagement convex portion 108 is engaged with one of the first engagement concave portion 94 and the second engagement concave portion 95, the elastic deformation portion 106 is elastically deformed forward, thereby engaging the engagement lever. The joint protrusion 108 is moved slightly forward. On the other hand, since the convex support part 107 that supported the engaging convex part 108 does not deform at this time, the engaging convex part 108 smoothly escapes from the first engaging concave part 94 and the second engaging concave part 95. When the engaging convex portion 108 reaches the position immediately before the other of the first engaging concave portion 94 and the second engaging concave portion 95, the engaging convex portion 108 is caused by the force of the elastic deformation portion 106 returning to the free state (rear). Smoothly engages the other of the first engaging recess 94 and the second engaging recess 95.

In the actuator unit 80 having the configuration described above, the pressed protrusion 78 is engaged with the elongated hole 105 of the pressing portion 104 so as to be relatively movable, and the front surface of the right end portion of the front cover 90 is brought into contact with the rear surface of the lever support portion 52. The screw 110 inserted into the through hole 56 from the front of the lever support portion 52 is screwed into the female screw hole 96 and the lock unit 25 is integrated. (Fixed to the lever support 52).
When the actuator unit 80 and the lock unit 25 are integrated, the cancel lever 99 and the slide-type open lever 74 are interlocked by the action of the pressed protrusion 78 and the long hole 105. That is, when the cancel lever 99 is located at the cancel position, the slide-type open lever 74 is located at the non-operation position, and when the cancel lever 99 is located at the cancel release position, the slide-type open lever 74 is located at the action position. Further, as shown in FIGS. 3 to 6 and FIGS. 12 to 16, the lower end portion of the lock release lever 59 (and the slide type open lever 74 when the cancel lever 99 is located at the cancel release position) is the storage recess. 27 enters (positions) into the rear end of 27.

Next, the operation of the lock device 20 configured as described above will be described.
When the back door 12 is in the open state as shown by the phantom line in FIG. 1, the lock device 20 is in the unlocked state shown in FIG. That is, the striker 15 is located outside the striker entry groove 29 of the support case 26 (the striker 15 is not shown in FIG. 12), the hook 31 is located in the unlocked position by the biasing force of the torsion coil spring 47, and the pole 40 is twisted. Since the coil spring 48 is urged to rotate toward the engagement position, the unlocking engagement surface 42 is engaged with the half lock protrusion 35 of the hook 31.
When the back door 12 is closed from this state and the striker 15 enters the lock groove 33 (and the striker entry grooves 29 and 53), the hook 31 is twisted by the striker 15 against the urging force of the coil spring 47 in the clockwise direction of FIG. Rotate. Then, the striker 15 enters the lock groove 33 (and the striker entry grooves 29 and 53), and the hook 31 rotates to the half lock position (not shown). Then, the half lock projection 35 of the hook 31 contacts the engagement projection 43 of the pole 40. If the closing operation of the back door 12 is stopped in this state, the hook 31 is held in the half lock position.
When the back door 12 is closed from the half-locked state to the fully closed position, the striker 15 enters further into the lock groove 33 (and the striker entry grooves 29 and 53) as shown in FIG. 31 rotates to the locked position. Further, since the locking protrusion 34 of the hook 31 engages with the engagement protrusion 43 of the pole 40 and the counterclockwise rotation of the hook 31 is restricted, the striker 15 is locked by the lock groove 33 of the hook 31. (The escape from the lock groove 33 of the hook 31 and the

striker entry grooves

29 and 53 becomes impossible). At this time, regardless of whether the cancel lever 99 is located at the cancel release position (FIG. 3) or the cancel position (FIG. 5), the lock release lever 59 is set when the outside handle 13 is located at the initial position (non-operation position). Are positioned at the lock holding position, as shown in FIGS. 13 and 15, the lower end portion of the slide-type open lever 74 and the lower end portion of the lock release lever 59 (insertion piece 62) are both pressed portions 44. Separate from.

In order to release this locked state, first, an unlocking permission signal (wireless signal) is sent from the wireless remote controller to the signal receiving unit 14 so that the motor 83 (worm 85) and the worm wheel 87 are reversed and positioned at the cancel position. The cancel lever 99 is rotated to the cancel release position shown in FIGS. Then, the slide type open lever 74 located at the non-operating position slides on the unlocking lever 59 to the operating position (positions in FIGS. 3 and 4). In this state, the outside handle 13 is rotated to the operation position, and the lock release lever 59 is rotated to the lock release position against the rotational biasing force of the torsion spring 72 (see FIGS. 4 and 14). Then, as shown in FIGS. 4 and 14, the lower end portion of the slide-type open lever 74 is engaged with the pressed portion 44, and the pole 40 positioned at the engagement position is twisted against the urging force of the coil spring 48. Since it is rotated to the engagement position, the hook 31 is rotated to the unlock position side by the rotational biasing force of the torsion coil spring 47. Therefore, if the back door 12 is rotated to the fully open position side, the hook 31 is rotated to the unlock position, and the striker 15 escapes from the lock groove 33 (and the striker entry grooves 29 and 53) (the lock is released). Further, when detection means (not shown) detects that the hook 31 has been rotated to the unlock position, the supply of current from the power source to the motor 83 is automatically cut off, and the motor 83 stops the reverse rotation operation. Further, when the outside handle 13 is returned to the initial position by releasing the hand from the outside handle 13, the lock release lever 59 is rotated back to the lock holding position by the rotational biasing force of the torsion spring 72. The lower end portion is separated from the pressed portion 44, the pole 40 is rotated to the engagement position by the rotational biasing force of the torsion coil spring 48, and the engagement surface 42 is in contact with the half lock projection 35 when unlocked (see FIG. 12). .

Subsequently, when the outside handle 13 is rotated without sending an unlocking permission signal from the wireless remote controller to the signal receiving unit 14 in the locked state (from the wireless remote control to the signal receiving unit 14 in advance). The case where the outside handle 13 is rotated when the locking signal is sent and the cancel lever 99 is positioned at the cancel position) will be described.
When the cancel lever 99 is positioned at the cancel position, the slide-type open lever 74 is positioned at the non-operating position (see FIGS. 5 and 6), so that the lower end portion (insertion piece 62) of the lock release lever 59 is Although located in the rear end portion, the lower end portion of the slide type open lever 74 is not located in the rear end portion of the storage recess 27 (see FIGS. 15 and 16).
In this state (the state shown in FIG. 15), when the outside handle 13 is rotated to the operation position and the lock release lever 59 is rotated to the lock release position (see FIGS. 6 and 16), as shown in FIGS. Although the lower end portion (insertion piece 62) of the lock release lever 59 approaches the pressed portion 44 side, the lower end portion (insertion piece 62) of the lock release lever 59 does not contact the pressed portion 44. Therefore, the locking device 20 continues to lock the striker 15.

As described above, the lock device 20 of the present embodiment enables the unlock operation by the outside handle 13 thereafter only when the cancel lever 99 is rotated to the cancel release position in advance by the wireless remote controller (radio signal). Become.
Further, since there are only three members (lever) for controlling the hook 31 and the pole 40, the lock release lever 59, the slide type open lever 74, and the cancel lever 99, the number of parts is smaller than that of the conventional lock device. .
Furthermore, since the number of parts is reduced, it is possible to reduce the size of the entire locking device 20 as compared with the prior art.

Further, since the cancel lever 99 and the slide-type open lever 74 are directly linked, the number of parts is smaller than in the case where another member is interposed between the cancel lever 99 and the slide-type open lever 74, and the cancel lever 99 The power to the sliding open lever 74 can be reliably transmitted.
Even after the motor 83 stops rotating, the cancel lever is operated by the click stop mechanism (the first engagement recess 94, the second engagement recess 95, the elastic deformation portion 106, the protrusion support portion 107, and the engagement protrusion 108). 99 can be reliably positioned at the cancel release position and the cancel position. Moreover, since the configuration of the click stop mechanism is simple, it is possible to keep the manufacturing cost low.
Further, a part of the front cover 90 that houses the motor 83 and the worm wheel 87 is used as a click stop mechanism (first engaging recess 94, second engaging recess 95). Compared to the case where the first engaging recess 94 and the second engaging recess 95 are formed in the supporting member, the number of parts can be reduced.

In the present embodiment described above, the present invention is applied between the back door 12 of the vehicle and the vehicle body, but it is needless to say that the present invention can be applied between other doors (for example, side doors) of the vehicle and the vehicle body. .
Further, the lock device 20 may be provided on the vehicle body and the striker 15 may be provided on the door.
A key cylinder is provided on one of the door and the vehicle body, and when the key cylinder is unlocked by a key, the cancel lever 99 is positioned at the cancel release position, and when the key cylinder is locked, the cancel lever 99 is placed. The key cylinder and the cancel lever 99 may be linked so that is positioned at the cancel position.
Furthermore, you may provide the handle member linked with the lock release lever 59 in the location (for example, vehicle interior) different from a door.

The vehicle door locking device according to the present invention has a structure in which the unlocking operation by the handle is made effective only when the preliminary operation is performed before the handle provided on the door or the like is operated. It is possible.
