Description

  The present invention relates to a vehicle locking device capable of switching a locking device from a locked state to an unlocked state by the power of an actuator.

Patent Document 1 discloses a four-wheeled vehicle in which a striker S protrudes from a rear opening of a vehicle body and a latch mechanism (lock device) 10 that can be engaged with and disengaged from the striker S is provided at a rear door that opens and closes the rear opening. It is disclosed.
The latch mechanism 10 includes a latch case 13 and an outer case 21 that are detachable from each other.
The latch case 13 made of a conductive material is rotatable between an unlock position that is not engaged with the striker and a lock position that is engaged with the striker, and is urged to rotate toward the unlock position by the urging means. A latch (hook) 11, a ratchet (pole) 12 that can rotate between an engagement position that engages with the latch 11 that is positioned at the lock position and a non-engagement position that releases the engagement with the latch 11; A detection switch 17 having a detection piece 17a electrically connected to the case 13 and projecting from the contact portion 11e protruding from the latch 11, and a mounting piece 132c made of a conductive material in contact with the latch case 13. Built in.
On the other hand, the outer case 21 includes a release motor 34, a worm gear 33 fixed to the output shaft of the release motor 34, a worm wheel 32 that meshes with the worm gear 33, an output lever 31 that is linked to the worm wheel 32, and the latch mechanism 10. Motor positive electrode bracket 35a and motor negative electrode bracket 35b, one end of which is electrically connected to a power source provided outside the motor and the other end of which is electrically connected to release motor 34, and negative electrode connection terminal 36b extending integrally from motor negative electrode bracket 35b. And a positive electrode connection terminal 36 a that is electrically connected to the detection switch 17 at one end. The other end of the positive connection terminal 36a and the motor negative metal fitting 35b are electrically connected to a display lamp provided in the vehicle.

  When the latch case 13 and the outer case 21 are connected, the end of the output lever 31 protrudes into the latch case 13 and can be engaged with and disengaged from the ratchet 12. Further, the positive connection terminal 36a protrudes into the latch case 13 and is electrically connected to the detection switch 17, and the negative connection terminal 36b is electrically connected to the mounting piece 132c.

When the rear door is opened from the vehicle body, that is, when the ratchet 12 is separated from the latch 11 and the latch 11 is positioned at the unlock position by the urging force of the urging means, the detection switch 17 outputs a detection signal. Then, this detection signal is sent to the display lamp through the electric circuit for detecting the lock state constituted by the positive electrode connection terminal 36a, the motor negative electrode metal fitting 35b, the negative electrode connection terminal 36b, the latch case 13, and the detection switch 17. Light. Therefore, the passenger can recognize that the rear door is opened from the vehicle body.
On the other hand, when the rear door is rotated to the fully closed position, the latch 11 located at the unlock position rotates to the lock position while engaging with the striker, and engages with the ratchet 12 located at the engagement position. Thus, when the latch 11 rotates from the unlock position to the lock position, the contact portion 11e of the latch 11 presses the detection piece 17a, so that the detection switch 17 stops outputting the detection signal. Accordingly, since the display lamp is turned off, the passenger can recognize that the rear door is locked.
JP 2006-207192 A

In the locking device of Patent Document 1, it is possible to detect that the latch 11 is positioned at the locked position (the rear door is locked) and that the latch 11 is positioned at the unlocked position (the rear door is in the open state). There is a disadvantage that this detection system is complicated.
That is, in order to construct a detection system, the latch case 13 is formed of a conductive material, the mounting piece 132c and the detection switch 17 (detection piece 17a) are provided on the latch case 13, and the abutment portion 11e is further provided on the latch 11. Need to form. Therefore, the locking device of Patent Document 1 cannot be manufactured at a low cost.

In addition, by connecting the latch case 13 and the outer case 21, the positive connection terminal 36a and the detection switch 17, and the negative connection terminal 36b and the mounting piece 132c are electrically connected to form an electric circuit for detecting the lock state. Therefore, if the latch case 13 and the outer case 21 are not manufactured with high accuracy, the positive connection terminal 36a and the detection switch 17 or the negative connection terminal 36b and the mounting piece 132c may cause poor contact.
In addition, since there are many parts constituting the electric circuit, there is a high risk that contact failure may occur in this respect.

  An object of the present invention is to provide a vehicle locking device that can detect a locked state reliably while having a simple structure.

Vehicle locking apparatus of the present invention is capable striker disengageably provided on one of the openable door relative to the vehicle body and said vehicle body, the locking device provided on the other, striker the striker is capable enters A hook built in a lock case formed with a groove and rotatable between a lock position that engages with the striker and maintains the closed state of the door and an unlock position that releases the engagement with the striker; And a pole that can rotate 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 the hook, and an actuator case that is detachable from the lock case built in, and an actuator and, a first terminal and a second terminal capable separable from each other for rotating move the pawl disengaged position from the engaging position, When one end of the first terminal and the second terminal enters the lock case when the actuator case and the lock case are connected, and the hook rotates from the unlock position to the lock position side Bei give a pressed portion which is pressed by the pressing portion of the hook, the other of the first terminal and the second terminal is located at a position deviated from the rotation locus of the hook within the actuator case, and the A contact portion that forms an electric circuit that operates a door opening operation device provided on the vehicle main body by contacting with one terminal, and is separated from the one terminal when the pressed portion is pressed by the pressing portion. It is characterized in that it comprises.

  The hook includes a half-locking protrusion that holds the hook in a half-lock position between the locked position and the unlocked position by engaging with the pole, and the half-locking protrusion is the pressing part. It is preferable to serve as both.

  It is preferable that the half-lock protrusion is formed integrally with the peripheral surface of the hook.

According to the first aspect of the present invention, the electric circuit for operating the door opening operation device is composed of only the first terminal and the second terminal incorporated in the actuator case (since it does not exist in the lock case). ), The lock state detection system of the present invention has few components and is simple in structure. Therefore, it can be manufactured at a low cost.
Furthermore, the number of parts is small, and all the parts that make up the electric circuit are built in the actuator case. Compared to the case where the electric circuit is made by connecting the parts in the actuator case and the parts in the lock case. Therefore, there is little risk of contact failure. Therefore, the locked state can be reliably detected.

  According to the second aspect of the present invention, since the contact between the first terminal and the second terminal can be released using the half lock protrusion formed on the hook, it is not necessary to separately form the pressing portion on the hook.

  According to the third aspect of the present invention, since the half lock projection can be easily formed integrally with the hook by press molding, for example, the manufacturing cost of the hook can be further reduced. In addition, since the half-locking projection is formed on the peripheral surface of the hook, the thickness of the locking device does not increase due to this half-locking projection.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In addition, the direction in description of this embodiment is based on the arrow line direction described in the figure.
A rear opening 11 is formed on the rear surface of the vehicle 10, and the upper edge of the back door 12 having the same shape as the rear opening 11 rotates around the axis in the left-right direction at the upper edge of the rear opening 11. It is pivotally attached as free. As shown in FIG. 1, a metal striker 15 protrudes upward at the bottom of the rear opening 11. Further, a lock device 20 that can be engaged with and disengaged from the striker 15 is provided at a portion that forms the bottom surface of the back door 12 when it is in the fully closed position.

The locking device 20 has a structure described below. In addition, the up-down direction and the front-back direction when describing the locking device 20 are directions when the back door 12 is in the fully closed state.
As shown in FIGS. 2 to 6, the lock device 20 includes a lock unit 25 and an actuator unit 50.
The lock unit 25 is a unit extending substantially in the vertical direction when the back door 12 is located at the fully closed position. The metal rear case (lock case) 26 includes a storage recess 27 that is recessed in the center thereof, and a pair of left and right attachment pieces 28. A striker entry groove 31 is formed at the lower end of the rear wall 30 of the storage recess 27. Further, a columnar hook support shaft 32 and a pole support shaft 33 both project in the up-down direction on the rear wall 30.

A circular support hole 36 formed in the center of the hook 35 is rotatably fitted to the hook support shaft 32. A lock groove 37 is recessed on the peripheral surface of the hook 35, and a lock protrusion 38 and a half lock protrusion (pressing portion) 39 are protruded on the peripheral surface of the hook 35. The hook 35 is integrally formed by press molding of a metal plate, and the plate thickness is the same in all portions. The hook 35 is rotatable about the hook support shaft 32 between an unlock position shown in FIG. 4 and a lock position shown in FIG. Further, as shown in FIGS. 4 to 7, the hook support shaft 32 is attached with a winding portion of a torsion coil spring S1 having one end fixed to the rear wall 30 and the other end fixed to the hook 35. The hook 35 is always urged to rotate toward the unlock position by the urging force of the torsion coil spring S1.
A circular support hole 41 formed in the center of the pole 40 is rotatably fitted to the pole support shaft 33. An engaging portion 42 at the time of unlocking is formed at a portion of the peripheral surface of the pole 40 facing the hook 35, and a substantially arc-shaped engaging surface 43 is formed at the upper portion of the peripheral surface of the pole 40. Further, a pressed portion 44 is projected from the upper surface of the pole 40. The pole 40 is rotatable between the engagement position shown in FIGS. 5 and 6 and the non-engagement position shown in FIG. Further, as shown in FIGS. 4 to 7, a winding portion of a torsion coil spring S <b> 2 having one end fixed to the rear wall 30 and the other end fixed to the pole 40 is attached to the pole support shaft 33. The pole 40 is always urged to rotate toward the engagement position by the urging force of the torsion coil spring S2.
In this way, the left and right ends of the front cover (lock case) 46 are screwed to the left and right mounting pieces 28 of the lock unit 25 that houses the hook 35, the pole 40, the torsion coil spring S1, and the torsion coil spring S2. Yes. Therefore, the lower half of the front surface of the rear case 26 is closed by the front cover 46, and a connection opening is formed in the rear half of the front surface of the rear case 26.

The actuator unit 50 is a unit that is substantially orthogonal to the lock unit 25 and extends substantially in the front-rear direction when the back door 12 is located at the fully closed position.
The upper case (actuator case) 51 of the actuator unit 50 is formed with a storage recess 52 whose rear surface is open. At the front end portion of the right side surface of the upper case 51, a connecting cylinder portion 53 whose right end surface is open is projected. The left end surface of the connecting cylinder 53 is also open, and this opening communicates with the storage recess 52. A motor 56 is fixed to the front end portion of the upper wall 54 of the storage recess 52, and a worm 58 is fixed to an output shaft 57 of the motor 56.
The motor 56 is connected to the left end of a motor driving plus terminal 59 and a motor driving minus terminal 60, both of which are made of a conductive material. The motor driving plus terminal 59 and the right end of the motor driving minus terminal 60 are connected to each other. It is located in the connecting cylinder part 53. Further, a lock detection minus terminal (first terminal) 61 extends rearward from an intermediate portion of the motor drive minus terminal 60, and a rear end portion of the lock detection minus terminal 61 is bent with a contact portion 62. It has become. Since the lock detecting minus terminal 61 and the contact portion 62 are fixed to the upper wall 54, the lock detecting minus terminal 61 and the contact portion 62 cannot be deformed.
Further, the upper wall 54 and the connecting cylinder 53 are made of a conductive material in a substantially L shape in plan view, with one end positioned in the connecting cylinder 53 and the other end positioned on the right side of the lock detecting minus terminal 61. A lock detection plus terminal (second terminal) 63 is fixed. Further, the front end portion of the elastic detection piece 64 made of a conductive material is fixed to the rear end portion of the lock detection plus terminal 63. The portion excluding the front end portion of the elastic detection piece 64 can be elastically deformed, and the intermediate portion of the elastic detection piece 64 is always in contact with the contact portion 62 of the lock detection minus terminal 61 due to its elasticity. The rear end of the elastic detection piece 64 is a pressed portion 65 that protrudes rearward of the upper case 51.

On the upper wall 54, a worm wheel support shaft 66, a pressing lever support shaft 67, a stopper pin 68, and a rotation range regulating pin 69 having a cylindrical shape project downward.
A circular support hole 71 formed in the center of the worm wheel 70 is rotatably fitted to the worm wheel support shaft 66. Since the peripheral surface portion of the worm wheel 70 meshes with the worm 58, the worm wheel 70 rotates counterclockwise when the worm 58 rotates forward, and the worm 58 reverses when the worm wheel 70 rotates clockwise. Since the rotation range restricting pin 69 is fitted in an arcuate rotation range restricting groove 72 formed in the worm wheel 70 so as to be relatively movable, the rotation range restricting groove 72 restricts the rotation range restricting the rotation range of the worm wheel 70. It is limited to the range where it abuts on both ends of the pin 69. Further, since the worm wheel 70 is urged to rotate clockwise in FIGS. 4 to 7 by a first rotation urging means (for example, a torsion coil spring) (not shown), the worm wheel 70 is always in the rotation range. The restricting pin 69 is held at the initial position (position shown in FIGS. 4 to 6) in contact with the left end surface of the rotation range restricting groove 72. Further, a pressing protrusion 73 having a substantially arc-shaped pressing surface 74 is provided in the center of the lower surface of the worm wheel 70.
A circular center hole 77 of the press lever 76 is rotatably fitted to the press lever support shaft 67. Since the pressing lever 76 is urged to rotate counterclockwise in FIGS. 4 to 6 by the urging force (for example, a torsion coil spring) of the second rotation urging means (not shown), the pressing lever 76 is normally used. The engaging recess 75 provided in the right side surface is held at the initial position (position shown in FIGS. 4 to 6) where it engages with the stopper pin 68. Further, the pressing lever 76 includes an abutting portion 78, and the abutting portion 78 always abuts on the pressing surface 74 of the pressing projection 73. The lower portion of the pressing lever 76 protrudes below the upper case 51, and a pressing protrusion 79 is formed at the lower end portion of the pressing lever 76.
Further, the lower surface of the upper case 51 that houses the motor 56, the worm 58, the worm wheel 70, the pressing lever 76, and the like is closed by a lower cover (actuator case) 80.

The lock unit 25 and the actuator unit 50 configured as described above are coupled by inserting the rear end portion of the actuator unit 50 into the connection opening formed between the rear case 26 and the front cover 46 of the lock unit 25. .
When the lock device 20 is configured by coupling the lock unit 25 and the actuator unit 50 in this manner, the pressing protrusion 79 of the pressing lever 76 is formed in the housing recess 27 of the rear case 26 as shown in FIGS. To the right side surface of the pressed portion 44 of the pole 40. Further, the pressed portion 65 of the elastic detection piece 64 also enters a position on the same plane as the hook 35 in the storage recess 27 of the rear case 26. As shown in the drawing, the pressed portion 65 is located on the rotation locus of the half-locking projection 39 of the hook 35 (can contact the half-locking projection 39), but the other portions of the hook 35 are rotated. Deviated from the movement trajectory.
Further, as shown in FIG. 8, the connecting cylinder portion 53 of the actuator unit 50 is connected to a back door side connecting portion 82 provided on the back door 12. The back door side connecting portion 82 is connected to the motor via a motor driving conductive wire 83 electrically connected to the motor driving positive terminal 59 and a motor driving conductive wire 84 electrically connected to the motor driving negative terminal 60. It is electrically connected to the driving power supply 85. Further, the motor driving conductive line 83 is provided with a lock release switch 86 installed on the indoor front panel. The motor (actuator) 56, the motor drive plus terminal 59, the motor drive minus terminal 60, the back door side connection portion 82, the motor drive conductive wire 83, the motor drive conductive wire 84, the motor drive power supply 85, and the lock The release switch 86 constitutes an electric circuit for driving the motor.
The back door side connecting portion 82 is uncoupled via a lock detection conductive wire 87 electrically connected to the motor driving negative terminal 60 and a lock detection conductive wire 88 electrically connected to the lock detection positive terminal 63. The lock lighting lamp 89 and the lock detection power supply 90 are electrically connected. The motor driving minus terminal 60, the lock detecting minus terminal 61, the lock detecting plus terminal 63, the elastic detecting piece 64, the back door side connecting portion 82, the lock detecting conductive wire 87, the lock detecting conductive wire 88, The lock detection lamp 89 and the lock detection power supply 90 constitute a lock detection electric circuit.

Next, operations of the lock device 20 and the unlocking lamp 89 configured as described above will be described.
When the back door 12 is in the open state as indicated by the phantom line in FIG. 1, the locking device 20 is in the unlocked state in FIG. That is, the striker 15 is positioned outside the striker entry groove 31 of the rear case 26, the hook 35 is positioned at the unlocked position by the biasing force of the torsion coil spring S1, and the pole 40 is unlocked by the biasing force of the torsion coil spring S2. The locking engaging portion 42 engages with the half-locking projection 39 of the hook 35.
At this time, the pressed portion 65 of the elastic detection piece 64 is not in contact with the half lock projection 39 of the hook 35, so that the elastic detection piece 64 contacts the contact portion 62 of the lock detection minus terminal 61. For this reason, the lock detecting electric circuit is closed and the lighting lamp 89 is lit when unlocked. Therefore, the driver and the passenger can recognize that the back door 12 is opened (the lock device 20 is in the unlocked state).

When the back door 12 is closed from this state and the striker 15 enters the striker entry groove 31 and the lock groove 37 of the hook 35, the striker 15 causes the hook 35 to rotate clockwise in FIG. Then, as shown in FIG. 5, the striker 15 enters the striker entry groove 31 and the lock groove 37, and the hook 35 rotates to the half-lock position shown in FIG. If the closing operation of the back door 12 is stopped in this state, the half lock projection 39 of the hook 35 comes into contact with the engagement surface 43 of the pole 40 as shown in FIG. Held in position.
At this time as well, the pressed portion 65 of the elastic detection piece 64 is not in contact with the half-locking projection 39 of the hook 35, so that the elastic detection piece 64 contacts the contact portion 62 of the lock detection negative terminal 61 and is unloaded. The lock-on lamp 89 lights up.
Further, when the hook 35 rotates from the unlock position to the half lock position, the half lock protrusion 39 of the hook 35 slightly rotates the pole 40 in the counterclockwise direction of FIG. Then, since the pressed portion 44 of the pole 40 is separated from the pressing protrusion 79 of the pressing lever 76, the rotational force of the pole 40 is not transmitted to the pressing lever 76 (actuator unit 50).

When the back door 12 is closed from the half-locked state to the fully closed position, the striker 15 enters further into the striker entry groove 31 and the hook 35 rotates to the locked position as shown in FIG. Further, since the locking projection 38 of the hook 35 engages with the engaging surface 43 of the pole 40 and restricts the counterclockwise rotation of the hook 35, the striker 15 is locked by the lock groove 37 of the hook 35 ( The hook 35 cannot escape from the striker entry groove 31).
At this time, as shown in FIG. 6, the half lock projection 39 of the hook 35 presses the pressed portion 65 of the elastic detection piece 64 to the right side, so that the elastic detection piece 64 is elastically deformed and separated from the contact portion 62. For this reason, the current of the lock detection power supply 90 does not flow in the lock detection electric circuit, and the unlocking lighting lamp 89 is turned off. Therefore, the driver and the passenger can recognize that the back door 12 is completely closed (the lock device 20 is locked).
Further, even when the hook 35 rotates from the half-lock position to the lock position, the half-lock protrusion 39 of the hook 35 slightly rotates the pole 40 counterclockwise in FIG. It is not transmitted to the lever 76 (actuator unit 50).

In order to release such a locked state, the lock release switch 86 is pushed. Then, the electric circuit for driving the motor is closed and the current of the motor driving power supply 85 flows to the motor 56, so that the motor 56 rotates normally. Then, as shown in FIG. 7, this power is transmitted from the worm 58 to the worm wheel 70, and the worm wheel 70 rotates counterclockwise in FIG. Further, the pressing lever 76 pressed by the pressing surface 74 of the worm wheel 70 rotates in the clockwise direction in FIG. 6, and the pressing projection 79 of the pressing lever 76 presses the pressed portion 44 of the pole 40 to the left side in FIG. . Then, as shown in FIG. 7, since the pole 40 rotates counterclockwise to the non-engagement position, the hook 35 is rotated to the unlock position by the rotational biasing force of the torsion coil spring S1, and the striker 15 is locked to the lock groove 37. And it escapes from the striker entrance groove 31 (the lock is released).
When the hook 35 rotates to the unlocked position, the elastic detecting piece 64 separated from the half-locking projection 39 is restored to its original position by its own elastic force as shown in FIG. Since the contact portion 62 comes into contact again, the lock detection electric circuit is closed again and the unlocking lamp 89 is lit.
When the lock is released in this way, the current supply from the motor driving power supply 85 to the motor 56 is automatically cut off, so that the motor 56 stops rotating. Then, the pole 40 rotates in the clockwise direction of FIG. 7 by the rotational biasing force of the torsion coil spring S2. Further, the pressing lever 76 rotates counterclockwise to the initial position by the biasing force of the second rotation biasing means. Further, since the worm wheel 70 is rotated clockwise to the initial position by the urging force of the first rotation urging means, the worm 58 is reversed.

In the present embodiment described above, among the components constituting the lock detection electric circuit, those provided in the lock device 20 are the lock detection minus terminal 61 (motor drive minus terminal 60) and the lock detection plus terminal. Since only 63 and the elastic detection piece 64 are provided, the structure of the lock detection electric circuit is simple. Therefore, the lock detection electric circuit can be manufactured at low cost.
Further, the number of components of the lock detection electric circuit is small, and all of the components (lock detection minus terminal 61, lock detection plus terminal 63, and elastic detection piece 64) are built in the actuator unit 50 (lock). It does not exist in the unit 25). Therefore, the components of the lock detection electric circuit exist in both the lock unit 25 and the actuator unit 50, and the components of the lock detection electric circuit come into contact with each other when the lock unit 25 and the actuator unit 50 are coupled. Compared to this, there is less risk of contact failure, and a reliable lock detection operation can be realized.

Further, since the half-lock protrusion 39 of the hook 35 is used as a pressing portion that presses the pressed portion 65 of the elastic detection piece 64 when the lock is released, it is not necessary to separately form the pressing portion on the hook 35. . Moreover, since the half lock projection 39 is formed on the peripheral surface of the hook 35 with the same thickness as the other portions of the hook 35, the half lock projection 39 increases the thickness of the lock unit 25 in the front-rear direction. Never do.
Further, since the hook 35 can be easily formed by press forming a metal plate, the hook 35 can be manufactured at low cost.

In the present embodiment described above, the locking device 20 is provided on the back door 12 and the striker 15 is provided on the vehicle body. However, the locking device 20 may be provided on the vehicle body and the striker 15 may be provided on the back door 12.
Further, the unlocking lighting lamp 89 is employed as the door opening operation device, but a light emitter (for example, LED) other than the lamp, an alarm buzzer, or the like may be employed as the door opening operation device.
Further, an outdoor handle (not shown) provided on the back door 12 may be linked to the motor driving electric circuit. That is, when the outdoor handle is not operated (when locked), the motor driving electric circuit is opened (current flow is interrupted), and when the outdoor handle is opened (unlocked), the motor driving is performed. The electric circuit may be closed (current flows).

Further, the lower portion of the lock detecting minus terminal 61 can be elastically deformed, the rear end portion of the lock detecting minus terminal 61 protrudes rearward of the upper case 51, and the lock detecting portion 39 of the hook 35 detects lock. The lock detecting minus terminal 61 and the elastic detecting piece 64 may be contacted and separated by elastically deforming the rear end portion of the minus terminal 61. Further, both the lower end portion of the elastic detection piece 64 and the lower end portion of the lock detection minus terminal 61 may be protruded rearward of the upper case 51.
Furthermore, although this embodiment applies this invention to the back door 12 of a vehicle, of course, it is applicable also to the other doors (for example, side door) of a vehicle.
