Description

  The present invention relates to a door lock actuator.

  The vehicle door lock actuator rotates a lock lever of a door lock device disposed on a vehicle door to a lock position and an unlock position by driving a motor.

  In conventional door lock actuators such as those described in Patent Documents 1 and 2, when a lock lever is driven, energization of the motor is stopped by a timer when a predetermined time has elapsed after energization of the motor. The energization time for the motor needs to be set longer with some margin in order to move the lock lever to the lock position or the unlock position without fail.

  However, when the lock lever reaches the lock position or the unlock position, the rocking of the lock lever is mechanically restricted, so that the motor cannot be rotated despite being energized, and the motor makes a beeping sound. Is generated. In the worst case, if the motor is energized at the locked position or the unlocked position, the motor may burn out.

  For this reason, in the conventional door lock actuator, it is necessary to provide a protective element such as a PTC thermistor or a protective circuit to prevent the motor from being burned out.

  In view of the above problems, it is an object of the present invention to provide a door lock actuator that does not energize a motor while its operation is mechanically restricted.

  In order to solve the above-described problems, a door lock actuator according to the present invention includes a motor that rotates in a direction corresponding to the polarity of an applied voltage, and is rotated in a lock direction or an unlock direction by driving the motor. Provided with a cam member urged to return to the neutral position when the driving force is lost, and an arm portion connected to the lock lever of the door lock device, and is swingable from the lock position to the unlock position. A lock member, a switch member that is swingably disposed and holds a movable contact, a first fixed contact that is electrically connected to the motor, and a power source that can be connected to the motor and through the movable contact A second fixed contact and a third fixed contact that can be electrically connected to the first fixed contact, and the first fixed contact, the second fixed contact, and the third fixed contact are The movable contact is in contact with the first fixed contact and the second fixed contact and is not in contact with the third fixed contact, and the movable contact is in contact with the first fixed contact and the third fixed contact. A lock driving region that is in contact with and not in contact with the second fixed contact; and between the unlock driving region and the lock driving region, the movable contact is the first fixed contact and the second fixed contact. And a transition region in contact with the third fixed contact, wherein the cam member is capable of swinging the lock member from the lock position to the unlock position in the neutral position, and from the neutral position to the lock. The lock member is gradually narrowed in the unlockable range in the unlock direction while rotating to a predetermined lock completion angle in the direction, and the unlock position is moved from the neutral position to the unlock position. A pivot guide that gradually narrows the rockable swingable range of the lock member while rotating to a predetermined unlock angle in the direction, and by rotating further in the lock direction than the lock complete angle A first operating portion for swinging the switch member into the unlock drive region; and a second operation unit for swinging the switch member into the lock drive region by rotating further in the unlock direction than the unlock completion angle. An operating portion, wherein the lock member is capable of contacting the switch member, and swings to the lock position, thereby swinging the switch member in the lock drive region to the transition region, By swinging to the unlock position, the switch member in the unlock drive region is moved to the transition region. It is assumed that there is a restricting portion that is swung by.

  According to this configuration, when the lock member is driven by the motor, the cam member completely moves the lock member to the lock position or the unlock position, and then swings the switch member to stop energization of the motor. . Accordingly, it is possible to avoid mechanically stopping the rotation of the motor while energizing the motor, and it is possible to prevent the generation of a beep and the burning of the motor. For this reason, a motor protection circuit is unnecessary, and the cost can be reduced. In addition, when the lock member is swung to the lock position or the unlock position by manual operation, the lock member swings the switch member so that the electric circuit can be closed and the motor can be energized. Appropriate operation during the next power feeding is ensured.

A first operated part that can contact but not contact the second operating part, and a second operated part that cannot contact the first operating part but can contact the second operating part And may be provided.

  According to this configuration, since the first operation unit and the second operation unit can be designed independently, the timing of swinging the switch member can be freely set.

  In the door lock actuator of the present invention, the cam member may maintain its rotation by an inertial force immediately after the driving force of the motor is lost.

  According to this configuration, the switch member can be further swung after the motor is de-energized, so that the electric circuit can be completely blocked and chattering does not occur.

  In the door lock actuator of the present invention, the switch member can swing coaxially with the lock member, and the lock member and the switch member regulate relative swing angles with each other. Also good.

  According to this configuration, it is easy to move the switch member to the transition region by swinging the lock member.

  In the door lock actuator of the present invention, the swing guide portion is formed so as to sandwich a cam follower provided on the lock member, and the first cam surface and the second cam surface that restrict both ends of the swing range of the cam follower. A cam surface may be provided.

  According to this configuration, since the first cam surface and the second cam surface do not interfere with each other, the profile of the lock member in the lock direction and the profile of the lock member in the unlock direction can be freely set.

  According to the present invention, after the lock member is swung to the lock position or the unlock position by the rotation of the motor, the switch member is swung to open the electric path for supplying power to the motor. The motor is not energized while being regulated. As a result, the motor can be prevented from being burned out, so that a protective circuit is not necessary.

  Embodiments of the present invention will now be described with reference to the drawings. 1 and 2 show a door lock actuator according to one embodiment of the present invention. This door lock actuator is a device that drives or locks or unlocks a door lock device mounted on a vehicle door.

  The door lock device of the present embodiment includes a casing 1, a motor 2, a worm gear 3 that is rotated by the motor 2, a cam member 4 that is a worm wheel that is driven to rotate around a shaft 4a by the worm gear 3, and a door lock device. A lock member 6 having an arm portion 5 connected to a lock lever (not shown) for switching between a locked state and an unlocked state, and pivotally supported by a shaft 6 a so as to be swingable on the cam member 4. The switch member 7 pivotally supported coaxially with the member 6 is accommodated.

  The lock member 6 can swing between a lock position for locking the door lock device and an unlock position for unlocking the door lock device. The swing position shown by a solid line in FIG. 1 is the unlock position. There is a rocking position illustrated by a two-dot chain line. The lock member 6 is connected to a lock knob (not shown) provided on the vehicle door via a cable or the like, and can be manually moved between the lock position and the unlock position in accordance with the operation of the knock knob. is there.

  As shown in FIG. 2, the cam member 4 is rotationally biased by a return spring 8 so as to return to the neutral position shown in FIG. Further, when the cam member 4 is rotated by being driven by the motor 4, immediately after the driving force of the motor 4 is lost, the cam member 4 resists the urging force of the return spring 8 by its own inertial force, but slightly in the same direction. The rotation can be maintained.

  Further, as shown in detail in FIG. 3, the cam member 4 is provided with a swing guide portion 10 constituting a surface cam for receiving and guiding a cam follower 9 protruding from the lock member 6 on the upper surface thereof. The swing guide portion 10 includes a first cam surface 11 and a second cam surface 12 that sandwich the cam follower 9.

  The first cam surface 11 defines the limit position on the unlock position side of the rockable range of the lock member 6, and the second cam surface 12 defines the limit position on the lock position side of the rockable range of the lock member 6. . In FIG. 3, an angular position (origin) where the cam follower 9 is located at the neutral position of the cam member 4 defined by the return spring 8 is shown as a neutral angle NP. The swing guide 10 enables the lock member 6 to swing in the entire range from the lock position to the unlock position at the neutral angle NP.

  From the neutral angle NP to the predetermined lock completion angle LK shown in the figure, the swing guide part 10 changes the position of the first cam surface 11 radially inward, and from the neutral angle NP to the predetermined unlock completion angle UL shown in the figure. The position of the second cam surface 12 is shifted outward in the radial direction.

  When the cam follower 9 moves from the neutral angle NP toward the lock completion angle LK, that is, when the cam member 4 rotates clockwise (lock direction), the first cam surface 11 moves radially inward of the cam member 4. Therefore, the swingable range of the lock member 6 on the unlock position side is gradually narrowed, and the lock member 6 swings toward the lock position. The first cam surface 11 is formed so that the lock member 6 reaches the lock position when the cam member 4 rotates to the lock completion angle LK.

  Further, when the position of the cam follower 9 moves from the neutral angle NP toward the unlock completion angle UL, that is, when the cam member 4 rotates counterclockwise (unlock direction), the second cam surface 12 moves in the unlock direction. Since it moves, the rockable range of the lock member 6 in the lock direction is gradually narrowed, and the lock member 6 is swung toward the unlock position. The second cam surface 12 is formed so that the lock member 6 reaches the unlock position when the cam member 4 rotates to the unlock completion angle UL.

  The swing guide unit 10 includes the first cam surface 11 and the second cam from the lock completion angle LK to a predetermined overlock angle OL, and from the unlock completion angle UL to a predetermined overunlock angle OU, respectively. It extends | stretches so that the position of the radial direction of the surface 12 may not change.

  Therefore, the cam member 4 can be further rotated in the locking direction without swinging the locking member 6 from the lock completion angle LK to the overlock angle OL, and from the unlock completion angle UL to the over unlock angle OU. The locking member 6 can be further rotated in the unlocking direction without swinging.

  Further, the cam member 4 is further provided with a first operation portion 13 and a second operation portion 14 that are shifted in the axial direction of the shaft 4a at different angular positions on the outer periphery of a portion protruding downward in a cylindrical shape. ing.

  As shown in FIG. 4, the lock member 6 has a first restricting portion 15 and a second restricting portion 16 formed so as to protrude in the radial direction above both sides of the switch member 7.

  As shown in FIG. 5, the switch member 7 is shifted in the axial direction of the shaft 6 a at different angular positions, and the first operated portion 17 and the second operated portion 18 formed so as to protrude toward the cam member 4 side. Have The first operated portion 17 can abut on the first operating portion 13 of the cam member 4, but cannot abut on the second operating portion 14. Further, the second operated portion 18 cannot contact the first operating portion 13 of the cam member 4 but can contact the second operating portion 14.

  In addition, the switch member 7 includes a regulated portion 19 that is formed so as to protrude between the first regulating portion 15 and the second regulating portion 16 of the lock member 6. Thereby, the lock member 6 and the switch member 7 mutually regulate the relative rocking angle.

  Further, the switch member 7 is configured to hold the movable contact 20 having the three contact portions 20a, 20b, and 20c shown in FIG. 6 on the lower surface of the portion extending to the opposite side to the cam member 4.

  FIG. 7 shows the inner surface of the casing 1. The casing 1 is formed by molding resin, and a pair of motor terminals 21 and 22 connected to the input terminals of the motor 2, three input terminals 23, 24 and 25 connected to external circuits, and metal A first fixed contact 27 made of a plate, connected to the electric circuit 26 connecting the motor terminal 21 and the input terminal 23, the motor terminal 22 and contacting the contact portion 20a of the movable contact 20 held by the switch member 7, an input terminal 24, the second fixed contact 28 that contacts the contact portion 20 b of the movable contact 20, and the third fixed contact 29 that is connected to the input terminal 25 and contacts the contact portion 20 c of the movable contact 20 during molding. It is provided as an insert.

  The first fixed contact 27 extends in an arc shape over the entire swinging range of the contact portion 20a so that the first fixed contact 27 always contacts the contact portion 20a of the movable contact 20 even when the switch member 7 swings. The second fixed contact 28 extends in an arc shape only in the upper portion in the figure of the swing range of the contact portion 20b. Further, the third fixed contact 29 extends in an arc shape only in the lower portion in the figure of the swing range of the contact portion 20c. Thus, the movable contact 20 contacts the first fixed contact 27 and the second fixed contact 28, but does not contact the third fixed contact 29, and the movable contact 20 is connected to the first fixed contact 27 and The movable contact 20 is located between the lock drive area AL that contacts the third fixed contact 29 but not the second fixed contact 28, and between the unlock drive area AU and the lock drive area AL. A transition area AN that contacts all of the contact 27, the second fixed contact 28, and the third fixed contact 29 is formed.

  The door lock actuator of the present embodiment having the above configuration is electrically configured as shown in FIG. The input terminals 23, 24, and 25 are combined in the combinations shown in the drawings when the door lock device is locked (unlocked → locked) and when the door lock device is unlocked (locked → unlocked). , Positive voltage, negative voltage, and no voltage are input.

  9 to 22, the locking and unlocking mechanism of the door lock device in the door lock actuator of this embodiment will be described in detail in order.

  FIG. 9 shows a normal unlocked state as in FIG. In the normal unlocked state, the movable contact 20 is positioned in the lock driving area AL as shown in the figure as a result of the unlocking operation described later. When locking by this door lock actuator, as shown in FIG. 8, a negative voltage is required for the input terminal 23, no voltage is applied to the input terminal 24, and a positive voltage is applied to the input terminal 25 for the locking operation described below. It is applied for a predetermined time obtained by adding a sufficient margin time to a possible time. When such a combination of voltages is applied, the motor 2 is configured to rotate the worm gear 3 in the forward direction and rotate the cam member 4 in the clockwise direction (lock direction).

  When the cam member 4 rotates in the locking direction, the first cam surface 11 moves the cam follower 9 to the inside in the radial direction of the cam member 4, so that the locking member 6 swings toward the locking position. When the lock member 6 swings to some extent, the first restricting portion 15 of the lock member 6 contacts the restricted portion 19 of the switch member 7 as shown in FIG. Then, further rocking of the lock member 6 results in the switch member 7 being rocked integrally by pressing the regulated portion 19 by the first regulating portion 15.

  As shown in FIG. 11, when the cam member 4 is rotated to the lock completion angle LK, the lock member 6 is swung to the lock position. By the rotation of the lock member 6, the switch member 7 is moved to the movable contact. 20 is swung to the transition region where it contacts the first fixed contact 27, the second fixed contact 28, and the third fixed contact 29.

  As shown in FIG. 12, when the cam member 4 further rotates from the lock completion angle LK toward the overlock angle OL, the lock member 6 does not swing any more, but the first operation portion 13 of the cam member 4 Only the switch member 7 is further swung by coming into contact with the first operated portion 17 of the switch member 7.

  As shown in FIG. 13, when the first operating portion 13 presses the first operated portion 17, the switch member 7 swings and the movable contact 20 does not come into contact with the third fixed contact 29. Since the voltage applied to the third fixed contact 29 cannot be transmitted to the first fixed contact 27 connected to the motor 2, the driving force of the motor 2 is lost.

  However, the cam member 4 continues to rotate in the locking direction against the return spring 8 due to its inertial force, but the switch member 7 is further swung as shown in FIG. The movable contact 20 is moved to the inside of the unlock driving area AU completely isolated from the third fixed contact 29. Thereby, even if the power supply to the input terminal 25 is continued, the chattering in which the movable contact 20 contacts the third fixed contact 29 intermittently is prevented.

  Thereafter, the cam member 4 is returned to the neutral angle NP by the return spring 8 as shown in FIG. However, the lock member 6 and the switch member 7 do not swing due to the return to the neutral angle NP of the cam member 4. That is, the second cam surface 12 is formed so that the cam follower 9 can be moved to a position corresponding to the unlock position of the lock member 6 in the range from the overlock angle OL to the neutral angle NP.

  When unlocked by this door lock actuator from this locked state, as shown in FIG. 8, a positive voltage is applied to the input terminal 23, a negative voltage is applied to the input terminal 24, and no voltage is applied to the input terminal 25. At this time, the fixed contact 20 is located in the unlock drive region AU, and the fixed contact 20 is electrically connected to the first fixed contact 27 and the second fixed contact 28. Therefore, the motor 2 rotates the worm gear 3 in the reverse direction. Then, the cam member 4 is rotated counterclockwise (unlock direction).

  The second cam surface 12 of the cam member 4 gradually moves radially outward from the neutral angle NP to the unlock completion angle UL, and narrows the rockable range of the cam follower 9 in the lock direction. Accordingly, the lock member 6 is swung toward the unlock position as the cam member 4 rotates in the unlock direction.

  As shown in FIG. 16, when the lock member 6 swings, first, the second restriction portion 16 of the lock member 6 contacts the restricted portion 19 of the switch member 7. Then, further rotation of the cam member 4 causes the lock member 6 and the switch member 7 to swing together.

  As shown in FIG. 17, when the cam member 4 rotates to the unlock completion angle UL and the lock member 6 swings to the unlock position, the switch member 7 moves the movable contact 20 to the first fixed contact 27, The second fixed contact 28 and the third fixed contact 29 are swung to the transition region.

  Further, when the cam member 4 is rotated from the unlock completion angle UL toward the over unlock angle OU, the lock member 6 does not swing any more, but as shown in FIG. 14 abuts on the second operated portion 18 of the switch member 7 to further swing the switch member 7.

  As the cam member 4 is further rotated, as shown in FIG. 19, the switch member 7 is swung to the lock drive region AL where the movable contact 20 does not contact the second fixed contact 28. As a result, power supply to the motor 2 is stopped, but the rotation of the cam member 4 due to the inertial force further swings the switch member 7 as shown in FIG. Position to the inside of AL.

  Thereafter, when the cam member 4 is returned to the neutral angle NP by the return spring 8, it returns to the state shown in FIG.

  In the door lock actuator of this embodiment, in addition to driving the motor 2 described above, the lock member 6 can be swung by an external force by a manual operation, that is, when the user operates the door lock device. For example, when the user performs a key operation on the door lock device, the lock lever of the door lock device swings, and in conjunction with this, the lock member 6 swings between the lock position and the unlock position. Further, when the lock knob (not shown) of the vehicle is manually operated by the user, the lock member 6 connected via a cable or the like swings between the lock position and the unlock position in conjunction therewith.

  As shown in FIG. 21, the lock member 6 is manually operated from the state of FIG. 9, and the lock member 6 in the unlock position indicated by the two-dot chain line is swung to the lock position indicated by the solid line. In this case, similarly to the case where the lock member 6 is swung by the rotation of the cam member 4, the first restricting portion 15 of the lock member 6 contacts the restricted portion 19 of the switch member 7 in the process, and the switch member 7 is swung. For this reason, when the lock member 6 is swung to the lock position, the movable contact 20 is moved to the transition region AN that contacts the first fixed contact 27, the second fixed contact 28, and the third fixed contact 29.

  Further, as shown in FIG. 22, the lock member 6 is manually operated from the state shown in FIG. 15, and the lock member 6 at the lock position indicated by the two-dot chain line is swung to the unlock position indicated by the solid line. In this case, the second restricting portion 16 of the lock member 6 comes into contact with the restricted portion 19 of the switch member 7 and swings the switch member 7 so that the movable contact 20 is moved to the first fixed contact 27 and the second fixed contact 27. It moves to the transition area AN which contacts the fixed contact 28 and the third fixed contact 29.

  As described above, in the door lock actuator of this embodiment, when the arm portion 5 is manually operated and the lock member 6 is swung to the lock position or the unlock position, the movable contacts 20 are both in the first position. The first fixed contact 27, the second fixed contact 28, and the third fixed contact 29 are brought into contact with each other. Thereby, even when the voltage combination for the locking operation shown in FIG. 8 is applied to the input terminals 23, 24, and 25, the voltage combination for the unlocking operation is applied, The lock member 6 can be swung by driving the motor 2 in a predetermined direction.

  The door lock actuator of the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the embodiment, the lock member 6 and the lock lever (not shown) of the door lock device are connected to each other. However, the lock member and the lock lever are connected via another intermediate member. Alternatively, the lock member 6 may be configured as a lock lever of a door lock device. Moreover, in the said embodiment, although it has comprised so that electricity supply of the motor 2 may be interrupted | blocked after the lock member 6 moves to a lock position and an unlock position, the lock member 6 moves to a lock position and an unlock position. At the same time or immediately before the movement, the motor 2 may be cut off from energization. Even in this case, the lock member 6 can be moved to the lock position or the unlock position by continuously rotating the cam member 4 even after the motor 2 stops due to the inertial force of the motor 2 and the cam member 4. is there.
