As shown in FIG. 2, a fork 11 and a pole 12 described later are stored in the first storage chamber 93a. The first storage chamber 93a is formed with an entrance 98 that is deeply cut out in a groove shape upward from the center of the lower edge. When the locking device 1 moves in accordance with the opening and closing of the tailgate 9, the striker 99 relatively enters the entrance 98.

  As shown in FIG. 1, the housing 94 includes a first housing 91 and a second housing 92, and is provided side by side on the upper surface rear end side of the mounting member 93.

  As shown in FIGS. 2 and 3, the first housing 91 and the second housing 92 are formed in a substantially box shape by injection molding of a thermoplastic resin. Then, the second housing chamber 91a is formed inside by assembling the first housing 91 located on the vehicle inner side (front) and the second housing 92 located on the tail gate 9 side (rear). It has become so. In the second storage chamber 91a, switching means 50 described later is stored.

  An opening 91c that allows the second storage chamber 91a to communicate with the outside is formed in the middle of the front side of the first housing 91 in the vertical direction. As shown in FIG. 2, the opening 91 c exposes a manual operation portion 61 c of a manual switching lever 61 described later to the outside of the housing 94. Since the manual operation portion 61c swings in the left-right direction around a switching lever swinging shaft 92c, which will be described later, the opening 91c is also elongated in the left-right direction, and has an elongated hole shape that draws an arc centered on the switching lever swinging shaft 92. ing. The opening 91c is indicated by a two-dot chain line in FIGS. 2, 5, and 6 because it is located on the front side of the paper with respect to the manual switching lever 61 and the like.

  As shown in FIG. 2, a fork 11 and a pole 12 are provided in the first storage chamber 93 a so as to sandwich the entrance 98 from the left and right.

  The fork 11 is disposed on the left side of the entrance 98 (left side when facing the front of the vehicle as shown in FIG. 2), and is erected from the bottom of the mounting member 93 into the first storage chamber 93a. The pivot shaft 14a is pivotally supported by the pivot shaft 14a. The fork 11 is biased by a coil spring (not shown) so as to swing counterclockwise around the swing shaft 14a. The “clockwise direction” and “counterclockwise direction” in this embodiment are based on the state facing the cross-sectional view of FIG.

  A portion of the fork 11 located on the entrance 98 side is branched into an upper convex portion 11a and a lower convex portion 11b. The striker 99 that has entered the entrance 98 is accommodated in the concave portion 11c formed between the upper convex portion 11a and the lower convex portion 11b. The state shown in FIG. 2 is a locked state in which the tailgate 9 is held closed by the fork 11 locking the striker 99 at the bottom of the entrance 98. A latch surface 19a that can be in contact with a stopper portion 12a, which will be described later, is formed on the tip side facing the pole 12 of the upper convex portion 11a. The outer peripheral edge of the fork 11 is formed in an arc shape in the clockwise direction from the tip of the upper convex portion 11a.

  The pole 12 is disposed on the right side of the entrance 98 (the right side when facing the front of the vehicle as shown in FIG. 2), and is erected from the bottom of the mounting member 93 into the first storage chamber 93a. The pivot shaft 14b is pivotally supported by the pivot shaft 14b. The pole 12 is biased by a coil spring (not shown) so as to swing clockwise around the swing shaft 14b.

  A portion of the pole 12 located on the entrance 98 side is formed so as to protrude toward the upper convex portion 11a of the fork 11, and its tip side is a stopper portion 12a. The stopper portion 12a is fixed so as not to swing the fork 11 counterclockwise by coming into contact with the latch surface 19a of the upper convex portion 11a when the fork 11 is engaged with the striker 99 at the bottom of the entrance 98. Thus, the tailgate 9 is locked.

  A portion of the pole 12 positioned above the swinging shaft 14b is formed so as to branch toward the lower surface of the first housing 91 and the second housing 92 while branching off from the stopper portion 12a. Part 12b. Although the details will be described later, the contacted portion 12b is pushed counterclockwise when the contact portion 51b that is one end of the automatic switching lever 51 or the contact portion 61b that is one end of the manual switching lever 61 contacts.

As shown in FIG. 5, when the abutted portion 12b is displaced counterclockwise, the pole 12 swings counterclockwise around the swing shaft 14b while resisting the biasing force of the coil spring. It has become. At this time, since the stopper portion 12a is separated from the latch surface 19a of the fork 11, the pole 12 opens the fork 11. For this reason, the fork 11 is swung counterclockwise around the rocking shaft 14 a by the urging force of the coil spring, and the striker 99 is displaced in a direction away from the entrance 98. As a result, the fork 11 switches to a state in which the striker 99 is not locked in the entrance 98, and the tailgate 9 is unlocked. At this time, the tailgate 9 is displaced from a completely closed state to a slightly opened state.

  On the other hand, when the striker 99 enters the entrance 98, the fork 11 and the pole 12 operate in the opposite manner to the above-described operation. As shown in FIG. 2, when the striker 99 enters the bottom of the entrance 98, the fork 11 swings to its original state, and the stopper portion 12a comes into contact with the latch surface 19a, so that the tailgate 9 is locked. Return to state. Thus, the lock device main body 90 can set the tailgate 9 to the locked state or the unlocked state.

  As shown in FIGS. 2 and 3, the switching unit 50 is stored in the second storage chamber 91 a and includes an automatic switching lever 51, a driving unit 80, and a manual switching lever 61.

  The automatic switching lever 51 has an elongated plate shape in which a sector gear 82d is formed on the upper side, a shaft hole 51a is formed in the center, and a contact portion 51b is formed on the lower side by injection molding of a thermoplastic resin. .

  The shaft hole 51 a is inserted through a switching lever swinging shaft 92 c that protrudes from the inside of the second housing 92 toward the first housing 91. For this reason, the automatic switching lever 51 can swing around the switching lever swinging shaft 92c. The contact portion 51b protrudes below the communication port 91d formed on the lower surface side of the first housing 91 and the second housing 92, and extends to the left side of the contacted portion 12b.

  A small-diameter gear 82c and a worm wheel 82b are disposed above the sector gear 82d, that is, on the upper right side of the second storage chamber 91a. The small-diameter gear 82c located on the front side and the worm wheel 82b located on the rear side are coaxial, and are integrally formed by injection molding of a thermoplastic resin or cutting processing of a metal material. As shown in FIG. 3, the small-diameter gear 82 c and the worm wheel 82 b include a boss portion 92 b protruding from the inside of the second housing 92 toward the first housing 91, and a boss portion 92 b inside the first housing 91. It is rotatably supported by a rotating shaft 95 whose both ends are inserted and fixed in a recessed portion 91b that is recessed in the facing portion.

  As shown in FIGS. 2 and 3, the small diameter gear 82c meshes with the sector gear 82d. On the other hand, the worm wheel 82b meshes with a worm gear 82a disposed below. The worm gear 82a is fixed to the rotation shaft of the motor 81 disposed on the upper left side of the second storage chamber 91a so as to be integrally rotatable.

  As shown in FIG. 3, an annular recess 92d coaxial with the worm wheel 82b is formed on the rear surface side of the worm wheel 82b, and a return spring 83 is disposed therein. As shown in FIG. 2, one end of the return spring 83 is locked to a housing side locking portion 83a that protrudes from the second housing 92 toward the rear surface side of the worm wheel 82b. On the other hand, the other end of the return spring 83 is locked to a worm wheel side locking portion 83b that protrudes from the rear surface side of the worm wheel 82b toward the second housing 92. For this reason, the worm wheel 82b is urged to rotate clockwise by the return spring 83.

  The motor 81 is electrically connected to a control unit (not shown) mounted on the vehicle. When the user attempts to open the tailgate 9 by opening the opening / closing handle 9a shown in FIG. 1, a control unit or the like mounted on the vehicle detects it and supplies power to the motor 81. Rotate. Then, the worm wheel 82b rotates counterclockwise through the worm gear 82a, and the small-diameter gear 82c also rotates counterclockwise integrally with the worm wheel 82b. As a result, as shown in FIG. 5, the automatic switching lever 51 swings in the clockwise direction via the sector gear 82d that meshes with the small diameter gear 82c. Here, the time when the automatic switching lever 51 is at the position shown in FIG. 2 is referred to as “initial position”, and the time when the automatic switching lever 51 is at the position shown in FIG. 5 is referred to as “maximum swing position”.

  Thereafter, for example, when the control unit or the like detects that a return condition that the user has finished opening the opening / closing handle 9a or that a certain time has passed, the electric power is not supplied to the motor 81. Then, the urging force of the return spring 83 causes the worm wheel 82b and the small-diameter gear 82c to rotate in the clockwise direction. As a result, the automatic switching lever 51 swings counterclockwise via the fan-shaped gear 82d. Return to position.

  A gear mechanism 82 is configured by including a sector gear 82d, a small diameter gear 82c, a worm wheel 82b, and a worm gear 82a. In addition, the drive unit 80 is configured to include a motor 81, a gear mechanism 82, and a return spring 83. As described above, the driving means 80 causes the motor 81 to swing the automatic switching lever 51 from the initial position to the maximum swing position, and the return spring 83 returns the automatic switching lever 51 from the maximum swing position to the initial position. Let

  As shown in FIGS. 2 and 3, the manual switching lever 61 has an elongated plate shape formed by injection molding of a thermoplastic resin, and is parallel to the front side of the automatic switching lever 51 in the second storage chamber 91a. It is arranged. The manual switching lever 61 has a manual operation portion 61c formed at the top, a shaft hole 61a formed at the center, and a contact portion 61b formed below. The manual switching lever 61 has cover portions 61e and 61f extending in a flat plate shape on both the left and right sides of the base of the manual operation portion 61c.

The shaft hole 61a is inserted through the switching lever swing shaft 92c. Therefore, manual switching lever 61, Ri automatic switching lever 51 coaxially der, and can swing in the switching lever pivot shaft 92c clockwise. The contact part 61b protrudes below the communication port 91d and extends to the left side of the contacted part 12b in the same manner as the contact part 51b.

  As shown in FIG. 3, the manual operation unit 61 c is a columnar protrusion that is integrally projected from the upper front surface of the manual switching lever 61 toward the front. The manual operation portion 61c extends through the opening 91c of the first housing 91 so as to be exposed to the inside of the vehicle.

  As shown in FIGS. 2 and 6, the manual switching lever 61 swings around the switching lever swinging shaft 92c when the user holds the manual operation unit 61c and moves it in the left-right direction. . Here, when the manual switching lever 61 and the manual operation unit 61c are in the positions shown in FIG. 2, they are called “initial positions”, and when the manual switching lever 61 and the manual operation unit 61c are in the positions shown in FIG. 5 or FIG. Will be referred to as the “maximum swing position”.

  As shown in FIG. 2, when the manual switching lever 61 and the manual operation unit 61c are in the initial positions, the manual operation unit 61c is located at the right end of the opening 91c. Here, the cover portion 61e is integrally formed so as to swell from the left side surface of the manual switching lever 61 to the left side, and on the left side of the base of the manual operation portion 61c, a flat plate extends from the second storage chamber 91a side along the opening 91c. The shape extends in a shape. For this reason, when the manual switching lever 61 is in the initial position, the manual operation part 61c and the cover part 61e cover the opening 91c from the second storage chamber 91a side.

  On the other hand, as shown in FIG. 5 or FIG. 6, when the manual switching lever 61 and the manual operation unit 61c are at the maximum swing position, the manual operation unit 61c is located at the left end of the opening 91c. Here, the cover portion 61f is integrally formed so as to swell from the right side surface of the manual switching lever 61 to the right side, and on the right side of the root of the manual operation portion 61c, a flat plate extends from the second storage chamber 91a side along the opening 91c. The shape extends in a shape. For this reason, when the manual switching lever 61 is in the maximum swing position, the manual operation portion 61c and the cover portion 61f cover the opening 91c from the second storage chamber 91a side.

  As shown in FIGS. 2 and 3, in the manual switching lever 61, a concave portion 61 d is formed in a middle portion between the manual operation portion 61 c and the shaft hole 61 a so as to penetrate a round hole.

  On the other hand, as shown in FIGS. 3 and 4, in the automatic switching lever 51, a U-shaped groove 51c is provided in the middle portion between the sector gear 82d and the shaft hole 51a. A cantilever 51e extending from the sector gear 82d toward the shaft hole 51a is formed inside the U-shaped groove 51c. A hemispherical convex portion 51d is formed on the front surface on the distal end side of the cantilever portion 51e. The U-shaped groove 51c, the cantilever portion 51e, and the convex portion 51d are integrally formed at the same time when the automatic switching lever 51 is formed by injection molding of a thermoplastic resin. The convex portion 51d can be displaced rearward by the elastic deformation of the cantilever portion 51e.

  When the automatic switching lever 51 and the manual switching lever 61 are in the initial positions shown in FIG. 2 and overlap when viewed in the front-rear direction, the convex portion 51d faces the concave portion 61d and fits into the concave portion 61d. Yes. In this state, the manual switching lever 61 is restricted so as not to swing around the switching lever swinging shaft 92c. In this case, as shown in FIG. 5, when the automatic switching lever 51 swings, the manual switching lever 61 swings integrally.

On the other hand, when the user operates the manual operation portion 61c to swing the manual switching lever 61 alone around the switching lever swing shaft 92c, the convex portion 51d does not face the concave portion 61d, and the edge of the concave portion 61d Abuts against the part. Then, the cantilever portion 51e is so elastically deformed rearward, convex portion 51d is disengaged from the recess 61 d displaced rearward. As a result, as shown in FIG. 6, the manual switching lever 61 is not restrained by the concave portion 61d and the convex portion 51d, and can swing around the switching lever swinging shaft 92c independently of the automatic switching lever 51. . At this time, the user need not resist the resistance force of the motor 81, the gear mechanism 82, and the return spring 83, and can swing the manual switching lever 61 with a light force.

  The constraining means 70 is configured to include the concave portion 61d, the cantilever portion 51e, and the convex portion 51d. As described above, the restraining means 70 is provided between the automatic switching lever 51 and the manual switching lever 61, and the manual switching lever 61 prevents the switching operation from occurring unless the manual switching lever 61 is manually swung. Is to be restrained.

  In the locking device 1 of the first embodiment having such a configuration, in the initial state shown in FIGS. 1 and 2, when the user attempts to open the tailgate 9 by opening the opening / closing handle 9a, the locking device 1 is mounted on the vehicle. The detected control unit or the like detects it and operates the motor 81 or the like as described above. Then, as shown in FIG. 5, the automatic switching lever 51 is driven and swung by the motor 81 or the like, and the contact portion 51 b that is one end of the automatic switching lever 51 contacts the contacted portion 12 b of the pole 12. The pole 12 is swung counterclockwise around the swing shaft 14b. As a result, the pole 12 does not fix the fork 11, the fork 11 swings counterclockwise around the swing shaft 14a, and the striker 99 is displaced in a direction away from the entrance 98. Thus, the lock device 1 automatically sets the tailgate 9 to the unlocked state. At this time, since the manual switching lever 61 is restrained by the restraining means 70 and swings integrally with the automatic switching lever 51, the switching operation of the automatic switching lever 51 is not hindered.

  On the other hand, in the locking device 1, when the motor 81 or the like becomes inoperable due to the battery rising or the like, or when the user tries to open the tailgate 9 from the inside of the vehicle, that is, when the driving means 80 is inoperative. The user holds the manual operation part 61c of the manual switching lever 61 and moves it from the initial position to the maximum position. Then, as shown in FIG. 6, the automatic switching lever 51 is not displaced in the initial state, so that the manual switching lever 61 is manually swung independently of the automatic switching lever 51. At this time, the restraining means 70 does not restrain the swinging of the manual switching lever 61 around the switching lever swinging shaft 92c because the convex portion 51d is displaced rearward and is detached from the concave portion 61d. Then, the contact portion 61b, which is one end of the manual switching lever 61, contacts the contacted portion 12b of the pole 12, and the pole 12 is swung counterclockwise around the swing shaft 14b. As a result, the fork 11 displaces the striker 99 in the direction in which the striker 99 is detached from the entrance 98 as in the case of the automatic switching operation described above. Thus, the lock device 1 manually sets the tailgate 9 to the unlocked state.

  Here, in the locking device 1 of the first embodiment, the cover portion 61e is integrally formed on the base side of the manual operation portion 61c.
