Description

BACKGROUND THE INVENTION

1) Technical field

The The present invention relates to a door locking device for a vehicle and in particular to a door locking device with a super locking mechanism, which is an actuation of a Button inside a vehicle makes it impossible to release a locked state, when the lock button is in a state in which opening a Door prevented is.

2) State of the art

A Door locking device with a super locking mechanism in addition to a locking mechanism to prevent it from opening a door from outside a vehicle is present in use. The super locking mechanism makes an operation of a lock button impossible within the vehicle, for an illegal access to solve a lock by an unauthorized operation of the lock button to prevent and improve the anti-theft performance. A Door locking device This type is constructed to be a super locking mechanism to be actuated by an actuator, which is activated according to a signal, which by a activity a remote control device or by a rotary operation of a key cylinder through a key is generated to switch the super locking mechanism to a superlocked state, about the operation the lock button impossible close. In this case it is necessary to use the locking mechanism to switch to a locked state, what means that the door lock device the actuator (actuator) to operate having the locking mechanism. Further, the door lock device thus constructed to the superlocked state of the super locking mechanism to solve, to set an unlocked state when the door goes through a key operation without activity of the actuator are opened can.

A first kind of a conventional one Door locking device includes two actuators for a super locking mechanism and a locking mechanism. The super locking mechanism or the locking mechanism is according to a selective actuation of the respective actuators operated in such a way that a superlocked state, a locked state or an unlocked state is set. The door lock device can the superlocked state by the super locking mechanism achieve a release operation of the Locking mechanism prevented by a lock button (See, for example, Japanese Patent Publication No. 3400747).

A second type of conventional Door locking device includes two actuators for a super locking mechanism and a locking mechanism, as with the first type of conventional Door locking device. This door lock device can be a super locked state by the super locking mechanism achieve what a release operation of the Locking mechanism by a locking button push on the Air prevented (see, for example, Japanese Patent Laid-Open Publication No. 2000-17921).

A third kind of a conventional one Door locking device is constructed to be a super locking mechanism or a locking mechanism according to an operation of a actuate individual actuator, to a superlocked state, a locked state or to achieve an unlocked state. The door locking device he aims the superlocked state through the super locking mechanism, what a release operation of release mechanism prevented by a locking button impact in the air (see For example, Japanese Patent Publication No. 3029966).

at the first kind of conventional Door locking device is to unlock it in an unlocked state To switch state, required, first the actuator for the locking mechanism to press, to switch it to the locked state, and then the actor for to operate a super locking mechanism to the same in the switch superlocked state. Further, it is about the super locked Condition to switch to the unlocked state, required, first the actor for to operate the super locking mechanism to the same in the switch locked state, and then the actuator for a To operate locking mechanism, to switch it to the unlocked state. Thus there is in this type of conventional Door locking device, because the actor for the locking mechanism and the actuator for the super locking mechanism operated sequentially Need to become, a problem in that a long operation time is required.

In the second type of conventional door Locking device is to switch an unlocked state in a super-locked state, it is necessary first to operate the actuator for the locking mechanism to switch the same in a locked state, and then to actuate the actuator for a super-locking mechanism to switch the same in a super-locked state , Thus, in this type of conventional door lock device, since the actuator for the lock mechanism and the actuator for the super lock mechanism must be sequentially operated to switch the unlocked state to the superlocked state, there is a problem that a long operation time is required.

at the third type of conventional Door locking device is used such an actuator that a neutral position in an actuator is set, and a superlocked state is by an actuation of the actuator from the neutral position in one direction over one Locked state is set while unlocked by an operation is set from the neutral position in the other direction. Therefore, in this type of conventional door lock device, since switching to the superlocked state or unlocked Condition must go through the locked state, a problem that a long operation time is required.

Further becomes in the second and the third kind of conventional Door locking devices the superlocked state by the super locking mechanism achieves what a release operation of the Locking mechanism by the lock button does not make available. In this case, the lock button is designed to pass through a spring or the like in its initial position (a position the locked state), when the lock button is in a position for the release operation by a hand of a User is solved in a vehicle, after the release operation is not is available. However, if the super locking mechanism of the superlocked State in a dissolved Condition is attributed The super locking mechanism can not be in the released state be switched if the lock button in the position for the Release operation is actuated.

DETAILED DESCRIPTION

Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 to 4 FIG. 13 are schematic diagrams of a door lock device according to a first embodiment of the present invention. FIG. The door lock device described herein is interposed between an outer handle D1 serving as a door handle and a latch mechanism 20 in a side door (a door D on a driver's seat side in a vehicle having a right side steering wheel) of a front link disposed on a right side of a front seat of a vehicle or an automobile, and is provided with a main body 2 and a sub housing 3 fitted. The main body 2 and the sub housing 3 are each made of synthetic resin. A housing 10 is by connecting the main body 2 and the secondary housing 3 together and by attaching them with fasteners 4 how to set up screws.

That through the main body 2 and the sub housing 3 built housing 10 is with a latch mechanism receiving unit 11 extending along an inner and outer direction of the door D and a lock mechanism receiving unit extending from an end of the latch mechanism receiving unit 11 which is positioned on an inner side, extends along front and rear directions of the door D, and appears as an L-shape from above. As in 4 shown is a sealing element 5 between sections of connected surfaces of the main body 2 and the secondary housing 3 inserted from a lower side of a vehicle front side to a vehicle rear side (the latch mechanism receiving unit 11 ) extend over a vehicle upper side, so that its desired waterproof property can be ensured.

The latch mechanism receiving unit 11 of the housing 10 has a horizontally notched groove in an approximately central portion in a height direction thereof 13 extending horizontally from a vehicle interior side to a vehicle exterior and the latch mechanism 20 in it.

The latch mechanism 20 is similar to a conventional one for holding a scraper S provided on a vehicle body of the automobile in an engaging manner and is provided with a pawl 21 and a ratchet wheel (a pawl) 22 equipped, as in 5A to 5C shown.

The handle 21 is arranged to over a jack shaft 23 being rotatable substantially horizontally along a longitudinal direction of the vehicle body in a position above the notched horizontal groove 13 in the latch mechanism receiving unit 11 extends. The handle 21 has an engagement groove 21a a hook section 21b and an engaging portion 21c ,

The engagement groove 21a the latch 21 is shaped to from an outer peripheral surface of the pawl 21 to the jack shaft 23 to be open. The engagement groove 21a is formed so as to have a width which allows a reception of the scraper S.

The hook section 21b the latch 21 is on the inner side of the engagement groove 21a positioned when the engagement groove 21a is opened down. As in 5A shown, the hook section stops 21b in a position (an opening position), in wel cher the notched horizontal groove 13 is open when the latch 21 around the jack shaft 23 is rotated in a clockwise direction. On the other hand, the hook portion 21b configured to stop in a position (a half-latched position) in which it has the notched horizontal groove 13 crosses, as in 5B shown, or in a position (a latched position), in which he the notched horizontal groove 13 crosses, as in 5C shown when the latch 21 around the jack shaft 23 is rotated in a counterclockwise direction.

The engaging section 21c the latch 21 is on the inner side of the engagement groove 21a positioned when the engagement groove 21a is opened down. As in 5A shown is the engaging portion 21c constructed so as to stop in a state that it has the notched horizontal groove 13 intersects and gradually upward to a depth (the outer side) of the notched horizontal groove 13 tends when the latch 21 around the jack shaft 23 is rotated in a clockwise direction. A pawl spring (not shown), which the pawl 21 always around the jack shaft 23 in a clockwise direction in 5A to 5C pretensioned, is between the pawl 21 and the latch mechanism receiving unit 11 intended.

The ratchet wheel (the pawl) 22 is below the notched horizontal groove 13 the latch mechanism receiving unit 11 and on the inside of the jack shaft 23 provided to over the ratchet wheel shaft 24 to be rotatable, which extends approximately horizontally along the longitudinal direction of the vehicle body. The ratchet wheel 22 has an engaging portion 22a and a work unit 22b ,

The engaging section 22a of the ratchet wheel 22 extends in a diametrically outward direction from the ratchet wheel shaft 24 to the outside. The engaging section 22a can the hook section 21b and the engaging portion 21c the latch 21 Press over a protruding end surface thereof when the ratchet wheel 22 in a counterclockwise direction in FIG 5A to 5C is rotated. The work unit 22b of the ratchet wheel 22 extends from the ratchet wheel shaft 24 to the inner side in a diametrically outer direction.

As in 4 . 6A and 6B shown is the ratchet wheel 22 with a ratchet lever 25 fitted. The ratchet lever 25 gets along with the ratchet wheel 22 around the ratchet wheel shaft 24 rotated to a position corresponding to the vehicle front. The ratchet lever 25 has a plant section 25a by bending one off the ratchet shaft 24 in the same direction as the work unit 22b of the ratchet wheel 22 extending portion in a direction of a vehicle front side (side of the locking mechanism receiving unit 12 ) and formed by bending a lower part of the bent portion toward the vehicle inside, and a working end portion 25b By bending a section that extends farther from the abutment section 25a extends up to the vehicle front, is formed in a direction to the vehicle interior. The ratchet lever 25 is coupled to together with the ratchet wheel 22 via a connecting pin 26 to be rotated, as in 5A to 5C shown. A ratchet spring (not shown), which is the ratchet wheel 22 always around the ratchet wheel shaft 24 in a counterclockwise direction in FIG 5A to 5C pretensioned, is between the ratchet wheel 22 and the latch mechanism receiving unit 11 intended.

In the latch mechanism 20 is a switch 27 , which is a position of the pawl 21 detected, above the latch 21 intended. The desk 27 is constructed such that a fitting thereof in sliding contact with an outer peripheral surface of the pawl 21 can come. The desk 27 that captures the pawl 21 in a latched position by a separation of the fitting from the outer peripheral surface of the pawl 21 is, and it turns on a vehicle interior lamp (not shown) or the like when the pawl 21 is in a position other than the latched position (eg, a released position and a half-latched position).

In the latch mechanism constructed as above 20 is how in 5A shown when the door D is in an open state (an open door state) relative to the vehicle body, the latch 21 positioned in a released position in which the interior light of the vehicle is turned on. When the door D is operated to open from this state, the scraper S provided on the vehicle body side proceeds in the notched horizontal groove 13 the latch mechanism receiving unit 11 before, to the engaging portion 21c the latch 21 to rest. As a result, the latch will 21 around the jack shaft 23 in a counterclockwise direction against an elastic force of a pawl spring (not shown). At the same time, the projecting end surface of the engaging portion slides 22a in contact with the outer peripheral surface of the pawl 21 so the ratchet wheel 22 clean around the ratchet wheel shaft 24 corresponding to a contour of the outer circumferential surface of the ratchet wheel 21 is rotated.

As in 5B That is, when the door D is further operated to close from the above state, since a feed amount of the scraper S becomes the notched horizontal groove 13 Gradually rising, the pawl 21 is further rotated in a counterclockwise direction, so that the engagement portion 22a of the ratchet wheel 22 the engagement groove 21a the latch 21 reached. Since in this state, the engaging portion 21c the latch 21 at the engagement portion 22a rests the ratchet wheel, the ratchet wheel 21 prevented, against a resilient restoring force of the ratchet spring (not shown) in a clockwise direction of the pawl 21 to be rotated. In addition, the hook section 21b the pawl is positioned to the notched horizontal groove 13 to cross, the scraper S is moved in a direction in which it from the notched horizontal groove 13 through the hook section 21b is released, that is, the door D is no longer actuated to open the vehicle body (half-latched state).

If, as in 5C shown, the door D is further operated to open from the half-latched state, the latch 21 continue to the jack shaft 23 in a counterclockwise direction over the engagement incision 21c rotated by the scraper S in the notched horizontal groove 13 advances, and the scraper S reaches the depth (the outer side) of the notched horizontal groove 13 , Meanwhile, the pawl 23 around the pawl shaft 24 in a clockwise direction in 5C against the elastic force of the ratchet spring (not shown) by applying the hook portion 21b the latch 21 on an upper surface of the engaging portion 22a is rotated, and is rotated in a counterclockwise direction against the elastic return force of the ratchet spring (not shown) just when the hook portion 21b the latch 21 through the engaging portion 22a happens. As a result, as in 5C shown as the hook section 21b the latch 21 at the engagement portion 22a of the ratchet wheel 22 is applied, the pawl 21 prevented from being rotated in a clockwise direction against the elastic restoring force of the pawl spring (not shown). Even in this condition, since the hook section 22b the latch 21 is positioned to the notched horizontal groove 13 to prevent the scraper S from being so moved to the depth (the inner side) of the notched horizontal groove 13 to exit, through the hook section 21b so that the door D is kept in a closed state thereof on the vehicle body (a full-latched state), and the inside lamp of the vehicle is turned off.

Furthermore, if the work unit 22b of the ratchet wheel 22 or the investment section 25a of the ratchet lever 25 around the ratchet wheel shaft 24 from the fully latched state in a clockwise direction in FIG 5C is rotated against the elastic force of the ratchet spring (not shown), the hook portion 21b the latch 21 and the engaging portion 22a of the ratchet wheel 22 detached from each other, leaving the latch 21 in a clockwise direction in 7 is rotated by the elastic restoring force of the pawl spring (not shown). As a result, as in 5A shown, the notched horizontal groove 13 opened, and the scraper S is made movable to the notched horizontal groove 13 leave, so that the door D is opened to open the door on the vehicle body, and the interior lamp in the vehicle is turned on.

In the latch mechanism 20 is through the switch 27 that captures the pawl 21 in the latched position, and when the pawl 21 is in a position other than the latched position (for example, a released position or a half-latched position), the interior lamp (not shown) or the like in the vehicle is turned on. Instead of the switch 27 Although not shown, a switch that detects a closed state or an open state of the door D may be provided between the vehicle body and the door D. For example, the switch has a detection piece that extends from the vehicle body to the door D. The switch detects the closed state of the door in such a case that the detection piece is pushed through the door D in the closed state of the door D. On the other hand, the switch detects the open state of the door in such a case that the detection piece is not blocked by the door D in the closed state of the door D (and the half-latched state of the latch mechanism 20 ) is pushed. The switch is also used as a switch for the interior lamp in the vehicle to turn off the interior lamp in the closed state of the door D and the interior lamp in the open state (and in the half-latched state of the latch mechanism 20 ) to turn on the door D.

As in 1 to 4 shown, takes the locking mechanism unit 12 of the housing 10 an opening lever 30 , a connecting lever 40 , an inside handle lever 50 , a locking mechanism 60 and a super locking mechanism 70 on.

In the locked state, even when the outer handle D1 is operated to open the door, the opening lever 30 in a clockwise direction in 1 to rotate, since the ratchet wheel drive unit 40b of the connecting lever 40 and the investment section 25a of the ratchet lever 25 are separated from each other, as in 11 shown the ratchet wheel drive unit 40b and the investment section 25a does not cause to abut each other so that the hook portion 21b the latch 21 and the engaging portion 22a of the ratchet wheel 22 not be resolved from each other. As a result, the door D is held in a closed state on the vehicle body, so that the vehicle can be locked.

With regard to switching or transferring from the in 10 shown unlocked state to the in 11 shown state, such a structure can be used, instead of the locking operation of the locking knob D3, the worm wheel 67 around the worm shaft 671 in a counterclockwise direction by the drive motor (which is in 4 is shown) is rotated such that the gear segment 65 around the gear shaft 651 is rotated in a clockwise direction. Alternatively, the key selector lever 62 for the lead 201 in a counterclockwise direction of the projection 201 be rotated by a key operation of the key cylinder RC, as in 9B shown.

When the lock button D3 for unlocking in the in 11 shown locked state is rotated, as in 10 shown, the locking lever rotated in a counterclockwise direction 76 the rotary shaft 72 in a clockwise direction. The connecting lever 63 gets the lead 201 in a clockwise direction according to the rotation of the rotary shaft 72 rotates. This is done with the connection lever 63 over the coupling projection 635 and the coupling groove hole 656 coupled gear segment 65 around the gear shaft 651 rotated in a counterclockwise direction. If the gear segment 65 is rotated in a counterclockwise direction by the emergency spring 663 preloaded emergency lever 66 around the gear shaft 651 in a counterclockwise direction in a locking manner with the gear segment 65 rotates.

Further, the connection lever 40 in a clockwise direction according to the rotation of the emergency lever 66 rotated so that the locking mechanism 60 is switched to the unlocked state.

With regard to switching from the in 11 shown locked state in the in 10 shown unlocked state, such a structure can be used that instead of the unlocking operation of the locking knob D3, the worm wheel 67 around the worm shaft 671 in a clockwise direction by the drive motor 675 (the in 4 is shown) is rotated such that the gear segment 65 around the gear shaft 651 is rotated in a counterclockwise direction. Alternatively, as in 9A shown, the key lever 62 for the lead 201 in a clockwise direction by a key operation of the key cylinder KC are rotated.

When in the opened state of the door D, the locking mechanism 60 is in the unlocked state, the locking mechanism 60 can not be switched to the locked state by simply pressing the lock button D3 to lock. This is because when the door D is in an opened state, that is, the latch 21 and the ratchet wheel 22 are not in the abutted and engaged state, as in FIG 4 and 6A shown, the working end section 25b of the ratchet lever 25 and the lock preventing portion 40b of the connecting lever 40 are positioned adjacent to each other, and the working end portion 25b of the ratchet lever 25 prevents the connecting lever 40 rotated in a counterclockwise direction. However, in the opened state of the door D, when the lock button D3 for locking is operated during a door opening operation guided by the outside handle D1 or the inside handle D2, the lock mechanism may be used 60 be switched to a locked state. This is because if the connecting lever 40 is moved upwards in accordance with a door opening operation of the door D by the outer handle D1 or the inner handle D2 even in the opened state of the door D, as in 6B and 7B shown, the adjacent relationship of the working end section 25b of the ratchet lever 25 and the lock preventing portion 40d of the connecting lever 40 is canceled, so that the working end section 25b of the ratchet lever 25 a rotation of the connecting lever 40 in a counterclockwise direction does not stop. In the open state of the door D is after the locking mechanism 60 is switched to the locked state, when the door D is closed in the usual way, the door D locked.

In this super-locked state, when the lock button D3 is operated to unlock, it rotates as shown in FIG 13 shown the locking lever rotated in a clockwise direction 76 the rotary shaft 72 in a clockwise direction. However, since the engagement groove 733 and the engaging projection 711 are separated from each other, only the engagement arm 73 together with the locking lever 76 rotates, and the connecting lever 63 is not rotated. That is, the engagement of the locking lever positioned in the locking position 76 gets off the connection lever 63 solved, and the locking lever 76 becomes for the connection lever 63 not made available, so that an actuation of the locked position of the locking lever 76 is made impossible to the unlocked position. As a result, even if the lock button D3 or the lock lever 76 are operated, the door D held in the closed state on the vehicle body, so that the vehicle can be locked.

Although in the in 12 not shown, when the lock button D3 is operated to the unlocked position, as shown in FIG 13 shown to be rotated, the locking lever 76 biased by a spring element or the like so as to fit into the in 12 to return to the position shown. However, the spring member does not stop an operation of the unlocked state or the locked state by the lock button D3 in the locked state or the unlocked state.

With a view to switching to the in 12 shown superlocked state, it is not necessary to switch from the in 11 necessarily shown executed locked state. Specifically, if the in 10 shown locking mechanism 60 in the unlocked state, the worm wheel becomes 75 around the worm shaft 751 in a counterclockwise direction by the drive motor 755 (the in 4 is shown) rotates. The gear segment 74 becomes the gear shaft 741 rotated in a clockwise direction, as in 12 shown. It will be in the gear segment 74 provided Verbindungsarmkopplungsnutloch 744 around the gear shaft in a clockwise direction. When the Verbindungsarmkopplungnutloch 744 is moved into the Verbindungsarmkopplungsnutloch 744 inserted connecting pin 713 of the connecting arm 71 around the rotary shaft 73 moved in a counterclockwise direction. The connecting lever 63 is in a counterclockwise direction according to the movement of the connecting pin 713 moved so that the locking mechanism 60 is switched to the locked state. At the same time it will be on the gear segment 74 provided Eingriffsarmkopplungsnutloch 745 around the gear shaft 741 moving in a clockwise direction as shown above. When the Eingriffsarmkopplungnutloch 745 is moved into the Eingriffsarmkopplungsnutloch 745 inserted connecting pin 734 of the engagement arm 73 in a predetermined diametrically outer direction (a direction S1 in FIG 12 ) of the rotary shaft 72 emotional. The intervention arm 73 slides in a direction to separate from the rotary shaft 72 (the direction S1 in 12 ) according to the movement of the connecting pin 734 , and the engaging groove 733 and the engaging projection 711 are separated from each other so that the super locking mechanism is switched to the superlocked state.

In the in 12 shown superlocked state is the worm wheel 75 around the worm shaft 751 in a clockwise direction by the drive motor 755 (the in 4 is shown) rotates. The gear segment 74 becomes the gear shaft 741 rotated in a counterclockwise direction as in 11 shown. It will do this on the gear segment 74 provided Eingriffsarmkopplungsnutloch 745 around the gear shaft 743 moved in a counterclockwise direction. When the Eingriffsarmkopplungnutloch 745 is moved into the Eingriffsarmkopplungsnutloch 745 inserted connecting pin 734 of the engagement arm 73 in a predetermined diametrically outer direction (a direction S2 in FIG 11 ) of the rotary shaft 73 emotional. The intervention arm 73 slides in one direction (direction S2 in 11 ) of approaching the rotary shaft 73 according to the movement of the connecting pin 734 , and the engaging groove 733 and the engaging projection 711 are engaged with each other so that the super locking mechanism 70 is switched to the released state and the locking mechanism 60 is switched to the locked state.

On the other hand, the worm wheel 67 around the worm shaft 671 in a clockwise direction by the drive motor 675 (the in 4 is shown) in the in 12 shown superlocked state rotates. The gear segment 65 becomes the gear shaft 651 rotated in a clockwise direction, as in 10 shown. In this case, the locking mechanism 60 switched to the unlocked state. At the same time the connection lever 63 for the lead 201 in a clockwise direction according to the rotation of the gear segment 65 rotates. When the connection lever 63 is rotated, the connecting pin 713 at the connection lever 63 provided Verbindungsarms 71 in a clockwise direction together with the connecting lever 63 emotional. The gear segment 74 becomes the gear shaft 741 in a counterclockwise direction via the connecting arm coupling slot 744 through the connecting pin 713 rotates. It will be in the gear segment 74 provided Eingriffsarmkopplungsnutloch 745 around the gear shaft 741 moved in a counterclockwise direction. When the Eingriffsarmkopplungnutloch 745 is moved into the Eingriffsarmkopplungsnutloch 745 inserted connecting pin 734 of the engagement arm 73 in a predetermined diametrically outward direction (see the direction S2 in FIG 11 ) of the rotary shaft 72 emotional. The intervention arm 73 slides in one direction (see the direction S2 in 11 ) of approaching the rotary shaft 72 according to the movement of the connecting pin 734 , and the engaging groove 733 and the engaging projection 711 are engaged with each other so that the super locking mechanism 70 is switched to the released state, as in 10 shown.

A switch from the in 12 shown superlocked state in the in 10 shown dissolved state (the unlocked state of the locking mechanism 60 ) can be done by rotating the key lever 62 for the lead 201 be executed by a key operation of the key cylinder KC, as in 9A shown to the connecting lever 63 for the lead 201 to rotate clockwise in one direction, as in 10 shown, instead of the drive motor 675 to operate. That is, by performing the switching from the super-lock state to the release state by the key operation of the key cylinder KC, it is made possible to release the super-lock state even if the drive motor fails 675 or the drive motor 755 occurs or when the voltage of a battery drops.

In the thus constructed door locking device are connecting arms 71 (the engaging projection 711 and the connecting pin 713 ), the intervention arm 71 (the locking pin 734 ) and in the gear segment 74 provided Eingriffsarmkopplungsnutloch 745 , which form the connection unit, provided in the structure, wherein the drive motor 675 , which involves switching the locking mechanism 60 between the locked state and the unlocked state, and the drive motor 755 , which involves switching the super locking mechanism 70 between the super-locked state and the released state, are provided. It is made possible by the connection unit, the drive motor 755 the super locking mechanism 70 drive to the super locking mechanism 70 to switch to the superlocked state while the locking mechanism 60 in the unlocked state. It is made possible by the connection unit, the drive motor 675 the locking mechanism 60 drive to the locking mechanism 60 to switch to the unlocked state while the super locking mechanism 70 in the superlocked state. As a result, it is made possible to reduce the operation time from the unlocked state to the super-locked state and the switching time from the super-locked state to the unlocked state, so that the entry and exit of the vehicle can be made swiftly Vehicle made especially speedy. As in the door lock device, the lock lever 76 for the connection lever 63 is not available, no collision occurs between the respective components, which is different from the conventional door lock device (see, for example, Japanese Patent Publication No. 343400747), which has such a structure that the operation for releasing the locked state is stopped by the lock button, so that no unnecessary burden on the respective components is given.

The ratchet lever 25 is coupled to together with the ratchet wheel 22 via a connecting pin 26 to be rotated, as in 5A to 5C shown.

The connecting lever 40 forms the release unit according to the present invention and it is at the opening working end portion 30b of the opening lever 30 appropriate. As in 15A . 15B . 16A and 16B shown has the connecting lever 40 an attachment hole 40a at its proximal end. The attachment hole 40a is in a turning piece 40aa formed in the connecting lever 40 is provided so as to be around an axial center along an inner and outer direction the vehicle body to be rotatable. The connecting lever 40 is provided so as to be vertical together with an opening operation end portion 30b to be movable, and it is at the opening operation end portion 30b so supported, about the axial center along an inner and outer direction of the vehicle body via the rotating piece 40aa by inserting the opening operation end portion 30b of the opening lever 30 into the attachment hole 40a to be rotatable. The connecting lever 40 with a ratchet wheel drive section 40b and the lever coupling portion 40c fitted.

The ratchet wheel drive section 40b of the connecting lever 40 extends in a diametrically outer direction from the attachment hole 40a to the investment section 25a of the ratchet lever 25 , The ratchet wheel drive section 40b is so provided as to be capable of the abutment portion 25a of the ratchet lever 25 in accordance with a high movement of the connecting lever 40 to press.

The lever coupling section 40c of the connecting lever 40 extends up from the attachment hole 40a to one side of the working end section 25b of the ratchet lever 25 , The extending portion of the lever coupling portion 40c is with an emergency lever coupling groove hole 40e as a vertical extending slot formed. A release lever coupling slot hole 40f which is a vertical extending slot is at a proximal end of the linkage portion 40c near the attachment hole 40a formed thereof. A protruding slot hole 40g projecting toward the vehicle rear side is below a lower end of the release lever coupling groove hole 40e educated.

The release lever 80 forms a release unit according to the present invention, and it is on the inside of the connecting lever 40 inside the case 10 provided as in 14 shown. The release lever 80 is rotatable about a release lever shaft 81 provided, which extends in an inner and outer direction of the vehicle and on the sub-housing 3 is appropriate. The release lever 80 is approximately formed with a C-shape and has a contact section 80a that is different from the release lever shaft 81 to the vehicle rear side up to above the working end section 25b of the ratchet lever 25 extends, and an operating portion 80b that is different from the release lever shaft 81 to the vehicle rear side up to the inside of the release lever coupling groove hole 40f in the connection lever 40 extends. The operating section 80b is with an engagement pin 80c fitted, which is inserted with the projecting slot hole 40g to be engaged.

According to the above-described door lock device, when the door D is in a closed state, when the lock mechanism 60 in an unlocked state, as in 17 shown the ratchet wheel drive unit 40b of the connecting lever 40 below the plant section 40a of the ratchet lever 25 positioned as in 15A and 16A shown.

In the unlocked state, the outside door opening handle D1 is operated to open the opening lever 30 around the opening lever shaft 31 in a counterclockwise direction in FIG 15A to rotate. At this time, the ratchet wheel drive section pushes 40b of the connecting lever 40 the investment section 25a of the ratchet lever 25 to make it upward according to an upward movement of the opening work end portion 30b to move, as in 15B shown. As a result, the hook portion becomes 21b the latch 21 and the engaging portion 22a of the ratchet wheel 22 detached from each other, so that the door D can be operated to open on the vehicle body.

In the unlocked state, the inner door D2 is operated to open the door to the inner handle lever 50 around the inner lever shaft 51 in a counterclockwise direction in FIG 16A to rotate. At this time, the ratchet wheel drive section pushes 40b of the connecting lever 40 the investment section 25a of the ratchet lever 25 to make it upward according to a high movement of the working end portion 50b of the inner handle lever 50 to move, as in 16B shown. As a result, the hook portion becomes 21b the latch 21 and the engaging portion 22a of the ratchet wheel 22 detached from each other, so that the door D can be operated to open on the vehicle body.

When in the closed state of the door D, as in 17 shown the locking button D3 is actuated to lock, while the locking mechanism 60 in the unlocked state, the locking lever rotated in a counterclockwise direction rotates 76 the rotary shaft 72 in a counterclockwise direction as in 18 shown. The connecting lever 63 gets the lead 201 in a counterclockwise direction according to the rotation of the rotary shaft 72 rotates. This is the gear segment 65 that with the connection lever 63 over the coupling projection 635 and the coupling groove hole 656 is coupled to the gear shaft 651 rotated in a clockwise direction. If the gear segment 65 is rotated in a clockwise direction, presses the Nothebelanlageabschnitt 655 of the gear segment 65 the gear abutment section 662 of the emergency lever 66 to the emergency lever 66 around the gear shaft 651 to rotate clockwise in one direction. Furthermore, the verbin dung lever 40 in a counterclockwise direction according to the rotation of the emergency lever 66 rotated so that the locking mechanism 60 is switched to the locked state.

When the connection lever 40 is rotated in a counterclockwise direction, it becomes engaged with the connecting lever 40 located release lever 80 around the release lever shaft 81 rotated in a clockwise direction around the abutment section 80a to move into such a position that the abutment section 80a at the working end section 25b of the ratchet lever 25 can be present, as in 18 shown.

In the locked state, even when the outer handle D1 is operated to open the door, around the opening lever 30 in a clockwise direction in 1 to rotate, since the ratchet drive section 40b of the connecting lever 40 and the investment section 25a of the ratchet lever 25 are separated from each other, as in 18 shown, the ratchet wheel drive section 40b and the investment section 25a not caused to abut each other, and the hook portion 21b the latch 21 and the engaging portion 22a of the ratchet wheel 22 are not resolved from each other. As a result, the door D is kept in the closed state on the vehicle body, so that the vehicle can be locked.

With regard to switching from the in 17 shown unlocked state to the in 28 In the locked state shown, instead of the locking operation performed by the lock button D3, the gear segment 65 around the gear shaft 651 in a clockwise direction by rotating the worm wheel 67 around the worm shaft 671 in a counterclockwise direction by the drive motor 675 , (in 14 is shown) are rotated. Alternatively, the key selector lever 62 for the lead 201 in a counterclockwise direction by a key operation of the key cylinder KC are rotated as in 9B shown.

If in the in 18 In the locked state shown, when the lock button D3 is operated to unlock, the lock lever rotated in a clockwise direction rotates 76 the rotary shaft 73 in a clockwise direction, as in 17 shown. The connecting lever 63 gets the lead 201 in a clockwise direction according to the rotation of the rotary shaft 72 rotates. This is done with the connection lever 63 over the coupling projection 635 and the coupling groove hole 656 coupled gear segment 65 around the gear shaft 651 rotated in a counterclockwise direction. If the gear segment 65 is rotated in a counterclockwise direction by the emergency spring 663 pretensioned emergency lever 66 around the gear shaft 651 in a counterclockwise direction in a locking (engaging) manner with the gear segment 65 rotates. Further, the connection lever 40 in a clockwise direction according to the rotation of the emergency lever 66 rotates, so that the locking mechanism is switched to the unlocked state.

With regard to switching from the in 18 shown locked state in the in 17 shown unlocked state, instead of the executed by the locking knob D3 unlocking operation, the gear segment 65 around the gear shaft 651 in a counterclockwise direction by rotating the worm wheel 67 around the worm shaft 671 in a clockwise direction by the drive motor 675 , (in 14 is shown) are rotated. Alternatively, as in 9A shown, the key lever 62 for the lead 201 in a clockwise direction by a key operation of the key cylinder KC are rotated.

When in the opened state of the door D, the locking mechanism 60 is in the unlocked state, the locking mechanism 60 be switched to the locked state by pressing only the lock button D3 to lock. If, however, the locking mechanism 60 in the opened state of the door D is switched to the locked state, the locking mechanism 60 be returned to the unlocked state in which the door D as it is closed. This is because when the door D is closed from the opened state, the latch mechanism 20 is switched over the halbingeklinkten state in the fully latched state. In particular, with reference to 5A and 5B the engaging portion 22a of the ratchet wheel 22 over the engaging section 21c the latch 21 in the course of the opened state ( 5A ) door D to the half-latched state ( 5B ). This is the work unit 22b of the ratchet wheel 22 moved upwards. Similarly, the engaging section climbs 22a of the ratchet wheel 22 about the work unit 21b the latch 21 in the course of the half-inserted state ( 5B ) to the full-latched state ( 5C ). This is the work unit 22b of the ratchet wheel 22 moved upwards. When the work unit 22b of the ratchet wheel 22 is raised, the Betätigungsendabschnitt 25b integral with the ratchet wheel 22 rotated ratchet lever 25 also moved upwards. It will, as in 18 shown, the release lever 80 moved to a position in which the abutment section 80a to the Operating end section 25b of the ratchet lever 25 can be present. That is, the operation end portion 25b of the ratchet lever 25 , which is moved upwards, pushes the plant section 80a of the release lever 80 up to the release lever 80 around the release lever shaft 81 to rotate in a counterclockwise direction, as in 17 shown. As a result, since the engagement pin 80c of the release lever 80 around the release lever shaft 81 is moved in a counterclockwise direction to the connecting lever 40 to rotate in a clockwise direction, the locking mechanism 60 switched to the unlocked state.

On the other hand, if the locking mechanism 60 in the open state of the door is switched to the locked state, the locking mechanism 60 be kept in the locked state by the door D is closed during a door opening operation of the outer handle D1 (or the inner handle D2). This is because of the connection lever 40 is moved upward in accordance with a door opening operation of the outer handle D1 (or the inner handle D2) and the engagement pin 80c of the release lever 80 at a lower end of the release lever coupling groove hole 40f of the connecting lever 40 is positioned as in 22 shown. That is, as in 23 shown, the investment section 80a of the release lever 80 is through the Betätigungsendabschnitt 25b of the ratchet lever 25 , which is moved upwards, pushed up to the release lever 80 around the release lever shaft 81 to rotate in a counterclockwise direction. Because, however, the engagement pin 80c of the release lever 80 which is moved around the release lever shaft in a counterclockwise direction into the projecting slot hole 40g of the connecting lever 40 progresses to a rotation of the connecting lever 40 to prevent in a clockwise direction becomes the locking mechanism 60 held in the locked state.

When the lock button D3 is operated to unlock in the super-locked state, the lock lever rotated in a clockwise direction rotates 76 the rotary shaft 72 in a clockwise direction, as in 20 shown. However, since the engagement groove 733 and the engaging projection 711 are separated from each other, only the engagement arm 73 integral with the locking lever 76 rotates, and the connecting lever 63 is not rotated. That is, the locking lever positioned in the locking position 76 is from the connection lever 63 solved, and the locking lever 76 is for the connection lever 63 not available, so that an actuation of the locking lever 76 is made impossible from the locked position to the unlocked position. As a result, even if the lock button D3 or the lock lever 76 is operated, the door D held in the closed state on the vehicle body, so that the vehicle can be locked.

Although not shown, the lock lever is 76 thus biased by a spring element or the like to be in the in 19 shown position when the lock button D3 in the in 19 shown super-locked state is actuated in the unlocked position to the locking lever 76 to rotate, as in 20 shown. However, the spring member does not stop an operation in the unlocked state or the locked state, which is performed by the lock button D3 in the locked state or the unlocked state.

With a view to switching to the in 19 shown superlocked state, it is not necessary to switch from the in 18 necessarily shown executed locked state. Specifically, if the in 17 shown locking mechanism 60 in the unlocked state, the worm wheel becomes 75 around the worm shaft 751 in a counterclockwise direction by the drive motor 755 (the in 14 is shown) rotates. The gear segment 74 becomes the gear shaft 741 rotated in a counterclockwise direction as in 19 shown. It will be in the gear segment 74 provided Verbindungsarmkopplungsnutloch 744 around the gear shaft 741 moved in a clockwise direction. When the Verbindungsarmkopplungnutloch 744 is moved into the Verbindungsarmkopplungsnutloch 744 inserted connecting pin 713 of the connecting arm 71 around the rotary shaft 72 moved in a counterclockwise direction. The connecting lever 63 is in a counterclockwise direction according to the movement of the connecting pin 713 rotated so that the locking mechanism 60 is switched to the locked state. At the same time that is in the gear segment 74 provided Eingriffsarmkopplungsnutloch 745 around the gear shaft 741 moving in a clockwise direction as shown above. When the Eingriffsarmkopplungnutloch 745 is moved into the Eingriffsarmkopplungsnutloch 745 inserted connecting pin 734 of the engagement arm 73 in a predetermined diametrically outer direction (a direction S1 in FIG 19 ) of the rotary shaft 72 emotional. The intervention arm 73 slides in one direction (direction S1 in 19 ) for separating from the rotary shaft 72 according to the movement of the connecting pin 734 , and the engaging groove 733 and the engaging projection 711 are separated, so the super locking mechanism 70 is switched to the superlocked state.

The worm wheel 75 will be around the snow ckenwelle 751 in a clockwise direction by the drive motor 755 (the in 14 is shown) in the in 19 shown superlocked state rotates. The gear segment 74 becomes the gear shaft 741 rotated in a counterclockwise direction as in 18 shown. It will be in the gear segment 74 provided Eingriffsarmkopplungsnutloch 745 around the gear shaft 741 moved in a counterclockwise direction. When the Eingriffsarmkopplungnutloch 745 is moved into the Eingriffsarmkopplungsnutloch 745 inserted connecting pin 734 of the engagement arm 73 in a predetermined diametrically outer direction (a direction S2 in FIG 18 ) of the rotary shaft 72 emotional. The intervention arm 73 slides in one direction (direction S2 in 18 ) to approach the rotary shaft 72 according to the movement of the connecting pin 734 , and the engaging groove 733 and the engaging projection 711 are engaged with each other so that the super locking mechanism 70 is switched to the released state and the locking mechanism 60 is switched to the locked state.

On the other hand, the worm wheel 67 around the worm shaft 671 in a clockwise direction by the drive motor 675 (the in 14 is shown) in the in 19 shown superlocked state rotates. The gear segment 65 becomes the gear shaft 651 rotated in a clockwise direction, as in 17 shown. In this case, the locking mechanism 60 switched to the unlocked state. At the same time the connection lever 63 for the lead 201 in a clockwise direction according to the rotation of the gear segment 65 rotates. When the connection lever 63 is rotated, the connecting pin 713 at the connecting lever 63 provided Verbindungsarms 71 in a clockwise direction together with the connecting lever 63 emotional. The gear segment 74 becomes the gear shaft 741 in a counterclockwise direction via the connecting arm coupling slot 744 through the connecting pin 713 rotates. It will be in the gear segment 74 provided Eingriffsarmkopplungsnutloch 745 around the gear shaft 741 moved in a counterclockwise direction. When the Eingriffsarmkopplungnutloch 745 is moved into the Eingriffsarmkopplungsnutloch 745 inserted connecting pin 734 of the engagement arm 73 in a predetermined diametrically outward direction (see direction S2 in FIG 18 ) of the rotary shaft 72 emotional. The intervention arm 73 slides in one direction (see direction S2 in 18 ) of approaching the rotary shaft 71 according to the movement of the connecting pin 734 , and the engaging groove 733 and the intervention procedure 711 are engaged with each other so that the super locking mechanism 70 is switched to the released state, as in 17 shown.

Switching from the in 19 shown superlocked state in the in 17 shown dissolved state (the unlocked state of the locking mechanism 60 ) can be done by rotating the key lever 62 for the lead 201 be executed by a key operation of the key cylinder KC, as in 9A shown to the connecting lever 63 for the lead 201 in a clockwise direction as in 17 rotate shown instead of the drive motor 675 to operate. That is, by performing the switching from the super-lock state to the release state by the key operation of the key cylinder KC, it is made possible to release the super-lock state, even if a failure in the drive motor 675 or the drive motor 755 occurs or the voltage of a battery drops.

When, in the opened state, it is detected by the open state detecting switch and the door D closed state that the door D is in the closed state, the super-lock mechanism can 70 by operating the drive motor 755 (the in 14 shown), are switched to the superlocked state as described above. If, however, the super locking mechanism 70 is switched to the open state of the door D in the super-locked state, it is made possible the locking mechanism 60 switch to the unlocked state to the super locking mechanism 70 in the released state by closing the door D without accompanying the door opening operation of the outer handle D1 (or the inner handle D2) due. This is because if the locking mechanism 60 in the opened state of the door D is switched to the locked state, as described above, the operation for returning the locking mechanism 60 in the unlocked state in the same manner as the operation for switching the super lock mechanism 70 from the super-locked state to the released state, by operating the drive motor 675 is performed.

When in the open state of the door D and in the super-locked state, the in 19 1, the door D is closed, and to accompany the door opening operation performed by the outer handle D1 (or the inner handle D2), the operating end portion pushes 25b of the upwardly moved ratchet lever 25 the investment section 80a of the release lever 80 to the release lever 80 around the release lever shaft 81 to rotate in a counterclockwise direction, as in 21 shown. Because the engagement pin 80c of the release lever 80 around the release lever shaft 81 is moved in a counterclockwise direction to the connecting lever 40 moving in a clockwise direction becomes the locking mechanism 60 switched to the unlocked state. When the locking mechanism 60 is switched to the unlocked state, the gear segment 65 around the gear shaft 651 rotated in a counterclockwise direction to the connecting lever 63 for the lead 201 to rotate clockwise in one direction. As a result, the super locking mechanism becomes 70 switched to the released state.

On the other hand, if the super locking mechanism 70 in the open state of the door D is switched to the super-locked state, the super locking mechanism 70 in the super-locked state, by closing the door D while maintaining the door-opening operation of the outside handle D1 (or the inside handle D2) in the super-locked state. This is because of the connection lever 40 is moved up to the engagement pin 80c of the release lever 80 at a lower end of the release lever coupling groove hole 40f according to the door opening operation of the outer handle D1 (or the inner handle D2), as in 22 shown. That is, as in 23 shown, the investment section 80a of the release lever 80 is moved up to the release lever 80 around the release lever shaft 81 in a counterclockwise direction corresponding to the upward-moving operating end portion 25b of the ratchet lever 25 to rotate. Because, however, the engagement pin 80c around the release lever shaft 81 in a counterclockwise direction, the release lever is moved 80 in the protruding groove hole 40g progresses to a rotation of the connecting lever 40 Turning clockwise in one direction will become the super locking mechanism 70 kept in the super-locked state.

In the thus constructed door locking device, the connecting arm 71 (the engaging projection 711 and the connecting pin 713 ), the intervention arm 73 (the locking pin 734 ), and the connection arm coupling groove hole 744 and the engagement-arm coupling slot hole 745 that in the gear segment 74 is provided, which form the connection unit, provided in the structure in which the drive motor 675 the switching of the locking mechanism 60 between the locked state and the unlocked state, and the drive motor 755 the switching of the super locking mechanism 70 between the super-locked state and the released state. It is made possible by the connection unit, the drive motor 755 the super locking mechanism 70 operate to the super locking mechanism 70 in the super-locked state, while the locking mechanism 60 in the unlocked state. It is also made possible by the connection unit, the drive motor 675 the locking mechanism 60 operate the locking mechanism 60 to switch to the unlocked state while the super locking mechanism 70 in the superlocked state. As a result, it is possible to reduce the switching time from the unlocked state to the super-locked state and the switching time from the super-locked state to the unlocked state so that it becomes comfortable for a passenger entering and leaving the vehicle, and in particular, entering the vehicle is made very comfortable. As in the door lock device, the lock lever 76 for the connection lever 63 is not available, no collision occurs among the respective components, which is different from the conventional door locking device (see, for example, Japanese Patent Publication No. 3400747), which has a structure such that the operation for releasing the locked state is stopped by the lock button so that a case in which the respective components are loaded can be prevented.

As in the door lock device, the release lever 80 and the connection lever 40 , which serve as a release unit, are provided when the super locking mechanism 70 in the opened state of the door D is switched to the super-locked state, the locking mechanism 60 switched to the unlocked state, and the super locking mechanism 70 is switched according to the operation of the connection unit in the released state. As a result, even if the super locking mechanism 70 is switched in the open state of the door D in the super-locked state, problems such as damage to the door lock device can be avoided.

A third embodiment of the present invention will be explained below. In the third embodiment, the same parts as in the first and second embodiments are denoted by the same reference numerals, an explanation thereof will be omitted, and parts or configurations different from the first and second embodiments will be explained below. More specifically, the configurations in the third embodiment that differ from the first and second embodiments include an operation guide unit according to the invention, which refers to the connection arm 71 and the intervention arm 73 refers.

The engaging projection 711 of the connecting arm 71 forms a work management unit according to the present invention.
