Japanese Patent No. 2664683 Japanese Patent No. 3452024

  Incidentally, as described above, when the door lock state of the door lock device is manually released in an emergency, the door lock device of Patent Literature 1 can operate the handle portion of the emergency lever to release the latch. In the door lock operation device, the latch release operation can be performed by turning the manual release knob, but in both cases, the handle of the emergency lever and the manual release knob are directly attached to the latch of the door lock device. There is a problem that the degree of freedom is low. In particular, in the case of an emergency door lock release device using an electric unlatching motor, even if it can be unlatched by operating the manual release knob, there is a problem that the manual release knob protrudes to the inside of the vehicle at normal times and is easily misoperated. .

  The present invention has been made based on the problems as described above, and an object of the present invention is to provide a vehicle door lock release device that can secure the degree of freedom of attachment of the latch release operation member and prevent erroneous operation. .

  According to a first aspect of the present invention, the door that opens and closes the door opening provided on the side of the vehicle body, the latch on the door side, and the striker on the door opening edge side are engaged to hold the door in a closed state. , Releasing the meshing between the latch and the striker and allowing the door to open, and transmitting the electrically generated operating force, thereby allowing the latch and striker of the door lock portion to An electric lock release means for releasing the engagement, and a manual lock release means for releasing the engagement between the latch of the door lock portion and the striker by transmitting an operation force generated by a manual operation. The manual unlocking means includes an operation lever pivotally supported on the vehicle interior side of the door and swingably forward from the front-rear center of the door. Oscillating end portion of the operating lever, characterized in that transmits the operation force to the door lock unit by being swung manually on the front side of the vehicle.

  According to a second aspect of the present invention, in the vehicle door lock release device according to the first aspect, the operation lever is pivotally supported in a recess formed in a trim that overlaps the inner panel of the door, and The swing end portion is disposed inward of the recess by a predetermined amount from the trim reference surface.

  According to a third aspect of the present invention, in the vehicle door lock release device according to the first or second aspect, the concave portion is provided at a front end portion of the trim.

  According to a fourth aspect of the present invention, in the vehicle door lock release device according to the first or second aspect, the operation lever is disposed at a position facing a foot of a passenger at a lower portion of the door.

  According to a fifth aspect of the present invention, in the vehicle door lock release device according to the first or second aspect, the operation lever is disposed at a position where a swing operation by a passenger in the front seat is possible. .

  According to the first aspect of the present invention, when the swing end portion of the emergency lever of the manual unlocking means is manually operated in an emergency, the latch of the door lock portion can be reliably engaged and released, and the emergency lever swings. Since the end portion is swung to the front side of the vehicle, it is not swung to the rear side that is easy to operate for the occupant seated normally, so that the occupant seated normally does not operate the lever. Can be prevented. Further, in the case of a slide door that slides toward the rear side of the vehicle and opens the door, the swing end of the emergency lever is swung in the direction opposite to the door opening direction (rear side) (front side). Therefore, the possibility that the occupant erroneously operates the emergency lever at the normal time can be further eliminated.

  In the invention of claim 2, the operation lever is pivotally supported in the recess formed in the trim, and when it is not operated, its swinging end is arranged in the recess by a predetermined amount from the trim reference surface. It is relatively easy to prevent from entering the passenger's line of sight and looks good.

  In the invention of claim 3, since the recess is provided at the front end portion of the trim, it is relatively less likely to enter the occupant's line of sight, the appearance is good, and the trim moldability is improved.

  According to the invention of claim 4, since the operation lever is formed at a position facing the occupant's feet so that the occupant cannot operate unless the seating posture is changed, it is possible to reliably prevent erroneous operation and to enter the occupant's eyes. It is small and looks good.

  In the invention of claim 5, since the front door occupant can also swing the operation lever of the rear door as well as the front door, the rear door can be unlocked, so safety management is performed by the front seat occupant, particularly the driver. This makes it possible to improve the safety of the rear passengers in an emergency.

FIG. 1 shows a vehicle C1 equipped with a door lock device to which a vehicle door lock release device as an embodiment of the present invention is attached.
The vehicle C1 includes a front door 2 that opens and closes the left and right front doorways 1 and a rear door 4 that opens and closes the left and right rear doorways 3.
The front door 2 is hinged at two locations h1 and h2 at the top and bottom of the front end, and the rotation end can be detached using a latch 66r and a striker Rs (see FIG. 3) at the front locking portion Jf at the middle of the center pillar 5 up and down. Locked.
The rear door 4 has two front and lower h3 and h4 at the front end hinged to the center pillar 5, and the rotating end is removably locked to the rear lock portion Jr in the middle of the rear pillar 60 using a latch and striker (not shown). The

Here, the front lock portion Jf of the front door 2 and the rear lock portion Jr of the rear 4 have the same configuration, that is, as shown in FIGS. 3 (a) to 3 (c), the strikers Rs opposed to the latches 66r respectively. On the other hand, the half-latch state is switched to the full latch state. The latch driving means 181 and the electric lock releasing means 180 connected to the front lock portion Jf and the rear lock portion Jr, and the controllers 30f and 30r have the same configuration. Therefore, here, the front lock portion Jf of the front door 2 and the latch drive means 181 attached thereto, the electric lock release means 180, the manual lock release means 200, and the controller 30f will be mainly described.
As shown in FIGS. 3A to 3C, the latch driving means 181 includes a drive gear 811 driven by a motor M1, and a bracket B1 driven by the drive gear 811 (FIGS. 3A and 3B). And a latch switching lever 82r which is a swing operation member supported so as to be swingable via a pivot 813.

Here, the front latch 66r of the front lock portion J1 includes a latch switching lever 82r, which is a swing operation member that is swingably supported by a bracket B1 that forms the base via a pivot 813, and a bracket B2 that is integral with the bracket B1. And a fork q0 that is swingably supported by the pivot end of the latch switching lever 82r, and a fork q0 that is swingably supported by the bracket B2 via the pivot 873. A pawl 880 that selectively engages the two protrusions q0 and restricts the fork q0 to a half latch state or a full latch state.
Note that the rotation end of the latch switching lever 82r rotates about the pivot 813 to switch the fork q0 from the half latch position to the full latch position. Here, the pole 880, which is biased clockwise around the pivot pin 873, sequentially engages with the two ends of the fork q0, and the pole switch swa moves the fork q0 to the half latch position and the full latch. Each time the position is restricted to the position, the on / off switching is sequentially performed twice.

  As shown in FIG. 4, the electric lock releasing means 180 supported by the front door 2 is means for releasing the meshing between the front latch 66r and the striker Rs by transmitting the operation force generated electrically to the releasing cable 806. It is. In addition, a manual lock releasing means 200 that transmits a manual operating force to the release cable 806 and releases the door lock in an emergency is connected to the electric lock releasing means 180 via a coaxial cable 211.

  Specifically, the electric lock release means 180 includes a release arm 801 (see FIG. 4) that swings by a solenoid (not shown), and an operation member 802 that operates around the fulcrum pin 803 in conjunction with the release arm 801. The pole 880 (see FIGS. 3A to 3C) of the front latch 66r connected to the other swinging end of the operation member 802 via the release cable 806 can be relatively displaced coaxially with the operation member 802. A second operating member 820 that is pivotally supported by the second operating member 820, and a protruding portion 822 that protrudes from the vicinity of the swing end of the second operating member 820 and includes a cancel arc groove 821.

As shown in FIG. 4, manual unlocking means 200 that is manually operated at the time of emergency unlocking is engaged with the cancel arc groove 821 via a coaxial cable 211 and a sliding pin 212 at one end thereof. When the electric lock releasing means 180 is released, the sliding pin 212 at one end of the coaxial cable 211 slides relative to the cancel arc groove 809, and the releasing drive of the releasing drive means 180 can be allowed. Further, when the operating force from the manual unlocking means 200 is applied to the proximal end of the cancel arc groove 809 via the slide pin 212, the hook 823 formed at the proximal end portion of the second operating member 820 is locked to the operating member 802 side. By doing so, the pole 880 can be released via the release cable 806, and the door lock can be released in an emergency.
Here, when the electric lock releasing means 180 is driven and the pawl 880 (see FIGS. 3A to 3C) of the front lock portion Jf is released, the pawl rotates around the pivot pin 873. The fork q0 can return to the unlatched position Pe (see the two-dot chain line in FIG. 3C).

The manual unlocking means 200 is connected to a coaxial cable 211 extending from the electric unlocking means 180, and as shown in FIGS. 5 and 6, the front panel inner panel 41p (see FIG. 6B) and It is pivotally supported in a lever housing portion 231 that is a recess formed in the trim 230 attached in a stacked manner.
Further, as shown in FIGS. 5 and 6B, the lever accommodating portion 231 is formed in a substantially rectangular concave shape with respect to the reference indoor surface f1 of the trim 230, and a through hole 233 is formed in the bottom portion 232 thereof. A bracket 234 is fitted there. The base end mb of the bracket 234 is fastened to the inner panel 41p with a bolt (not shown).
The protruding end mc of the bracket 234 from the through hole 233 pivotally supports the base end 236b of the lever 236 via the vertically oriented pin 235.

As shown in FIGS. 5 and 6 (b), the lever 236 is a bent piece, and the extending end side of the base end portion 236b is curved to form a swing end 236c. A portion 236a is formed, on which the coaxial cable 211 is locked.
Here, the lever 236 can be oscillated around the pin 235, and when the 236c is accommodated in the lever accommodating portion 231, the oscillating end portion 236c is recessed inward (in the vehicle width direction) by a predetermined amount ta from the trim reference surface f1. The non-operating position p1 provided on the outer side and the swing end 236c are formed so as to reach the operation position p2 when the swing end 236c is operated by the occupant and swings forward Xf.
That is, the non-operation position p1 is arranged at a position that can be recessed by ta in the recess.

As described above, the swinging end 236c at the non-operating position p1 is disposed inwardly by the predetermined amount ta from the trim reference surface f1, so that when a displacement movement of an occupant in the vehicle or an article in the vehicle occurs. Thus, it is possible to reliably prevent the swinging end portion 236c from being erroneously operated.
In addition, the non-operation position p1 is disposed at substantially the same position as the trim reference surface f1 in the vehicle width direction without being recessed in the recess with respect to the trim reference surface f1, and a surface that is substantially flat with the trim reference surface f1. It may be formed. The flat surface can sufficiently prevent the swinging end portion 236c from being erroneously operated when an occupant in the vehicle or an article in the vehicle is displaced.
Further, the lever swing end 236c here is formed so as to generate a release operating force by being manually swung to the front side Xf of the vehicle.

  As shown in FIG. 6B, when the swing end 236c swings from the non-operation position p1 to the operation position p2, the coaxial cable 211 engaged with the cable locking portion 236a of the lever 236 is electrically unlocked. A pulling operation force is applied to the protruding portion 822 having the cancel arc groove 821 on the means 180 side. In conjunction with this, the hook 823 (see FIG. 4) of the second operation member 820 transmits the rotational force to the operation member 802. This rotational force is transmitted as an operating force to the pawl 880 of the front latch 66r via the release cable 806, and when the pawl 880 is released, the pawl 880 returns to the unlatched position Pe (the difference between the two points in FIG. 3C). The fork q0 is switched to the unlatched state, the engagement between the front latch 66r and the striker Rs is released, the front lock portion Jf is unlocked, and the front door 2 can be opened.

  Here, the swinging end 236c is swung to the front side of the vehicle, which is opposite to the rear side, which is easy to operate for the occupant seated normally, so that the occupant seated normally operates the lever 236 incorrectly. Can be prevented.

Further, the lever accommodating portion 231 is formed in front of the center in the front-rear direction of the door and in a lower region (refer to a region E in FIG. 4) on the front end side of the trim 230. That is, it is formed at a part that cannot be reached by a seated occupant, or a position E that faces the feet of the occupant that cannot be operated unless the occupant changes the seating posture.
In addition, the operation lever 236 is formed at a position E that faces the occupant's feet so that the occupant who normally sits down cannot change the seating posture without changing the sitting posture. It is small and looks good.
Furthermore, since the lever accommodating portion 231 which is a concave portion is provided at the front end portion of the trim 230, it is relatively less likely to enter the occupant's line of view in this respect, and the appearance is good and the trim moldability is improved. Note that manual unlocking means 200 is provided on the rear door 4 side as well as the front door 2 side.

  Here, a similar configuration in which the operation lever 236 is pivotally supported in the lever accommodating portion 231 is provided on the inner panel 41p on the rear door 4 side. In this case as well, as shown in FIG. 5, a similar component portion in which the operation lever 236 is pivotally supported in the lever accommodating portion 231 with respect to the trim on the rear door 4 side is formed. In this case, in particular, the operation lever 236 on the rear door 4 side is disposed at a position where it can be swung relatively easily by the front seat occupant. As a result, the front seat occupant can swing the operation lever 236 on the rear door 4 side in the event of an emergency, so that even if the rear seat occupant is an elderly person or a child, the escape to the outside of the vehicle can be assisted. Will be improved. In particular, the driver can perform safety management.

  As shown in FIG. 2, the controllers 30f and 30r for controlling the electric lock releasing means 180 and the latch driving means 181 are connected to the vehicle body side main controller 70 so as to exchange signals with each other. An unillustrated input port of the controller 30f of the front door 2 opens an out handle switch 900 that outputs an unlock signal of the door out handle Hn and an inner unlock handle Hin attached to the door trim 230 that overlaps the door inner panel 41p. Each input signal is input from an inner handle switch 901 that outputs a lock signal, a pole switch swa that detects the movement of the pole 880 of the front lock portion Jf, and a full latch position sensor swc that detects the movement of the fork q0. The output port (not shown) of the controller 30f drives a motor M1 that drives a latch switching lever 82r (see FIG. 3) in the latch driving means 181 and a release arm 801 of the electric lock releasing means 180 (see FIG. 4). Connected to solenoid SL.

As a result, the controller 30f drives and controls the latch driving means 181 and the electric lock releasing means 180 so that the respective striker Rs of the front lock portion Jf is switched from the half latch state to the full latch state.
Next, the operation of the door locking device and the manual unlocking means 200 for holding the front door 2 to be opened and closed (the rear door 4 is similarly controlled) in the closed position will be described with reference to FIGS.

  It is assumed that the front door 2 is manually operated to unlock the door-out handle (also in the case of a door inner handle) Hn in a normal state. In this case, in response to the unlocking signal from the door-out handle switch 900, the controller 30f drives the electric unlocking means 180 of the front lock portion Jf in the unlocking direction, and the pole 880 of the front latch 66r is moved as shown in FIG. Is switched from the holding position Pt indicated by the solid line to the release position Pe indicated by the two-dot chain line. As a result, the fork q0 is unlocked and switched to the unlocked state shown in FIG. 3A, which is detected by turning off the full latch swc and turning on / off the pole swa. When this state is determined, the controller 30f stops the electric lock releasing means 180.

In this state, the front door 2 is opened and then manually closed. At that time, the front latch 66r of the front lock portion Jf reaches the half latch state of FIG. 3B from the unlatched state of FIG. When the half latch state is detected by the on / off switching of the pole swa, the controller 30f drives the motor M1, and the fork q0 is switched to the full latch by the latch switching lever 82r, and this full latch state is turned on of the full latch swc and the on / off of the pole swc. When it is detected by switching off, the latch driving means 181 is stopped.
During such normal operation, the front door 2 of the vehicle (the same applies to the rear door 4) is greatly deformed due to a collision or the like, and the controller 30f, an unillustrated power supply circuit connected thereto, and other wiring are cut off. Suppose you fall into time.

In such an emergency, the controller 30f and the electric unlocking means 180 connected to the controller 30f do not operate, and the front door 2 (the same applies to the rear door 4) remains locked.
In such a case, the passenger in the vehicle changes its posture from the seating position, and the swinging end portion 236c of the operation lever 236 (see FIGS. 5 and 6) of the manual unlocking means 200 is locked with a finger and the front of the vehicle. Xf is swung, the pawl 880 of the front latch 66r is switched to the unlocked position Pe (see FIG. 3C), the fork q0 is unlocked and the front latch 66r is unlocked as shown in FIG. Switch to. Thereby, even if the controller 30f side is inactive, the front lock portion Jf is switched to the unlocked state, and the front door 2 (which is also controlled in the case of the rear door 4) can be easily opened. In addition, normally, the swinging end 236c of the lever 236 is disposed inward by a predetermined amount ta from the trim reference surface f1, so that the lever 236 can be prevented from being erroneously operated.

  Next, FIG. 7 shows a vehicle C equipped with a door lock device to which a vehicle door lock release device according to the second embodiment of the present invention is attached.
