  By the way, a reduction in manufacturing cost is required for a locking device for a vehicle opening / closing body. In this regard, in the above-described conventional locking device, the switch for detecting that the handle is opened is separated from the locking device for the vehicle opening / closing body. Since it is provided outside the housing, a waterproof switch is required. In addition, since the electric motor and the switch are connected to the DC power source through two systems of wire harnesses, the number of wire harnesses and connectors increases. In particular, when the above-described locking / unlocking operation unit is also provided with a switch circuit for detecting that the user has performed the locking / unlocking operation, the switch constituting the switch circuit needs to have a waterproof configuration. In addition, the number of wire harnesses and connectors is further increased in order to connect the switch circuit to a DC power source or the like. For this reason, it is difficult to reduce the manufacturing cost of the conventional locking device.

  As shown in FIG. 3, 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. ing. 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 swings counterclockwise around the swing shaft 14 </ b> A by the urging force of the coil spring, and the striker 79 is displaced in a direction away from the entrance 78. As a result, the fork 11 is switched to a state where the striker 79 is not locked in the entrance 78, and the tailgate 9 is brought into an unlatched state. 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 79 enters the entrance 78, the fork 11 and the pole 12 operate in the reverse manner to the above-described operations. As shown in FIG. 2, when the striker 79 enters the bottom of the entrance 78, the fork 11 swings to the original state, and the stopper portion 12A comes into contact with the latch surface 19A to return to the latched state.

  As shown in FIG. 2, the electric motor 81 is disposed on the left side of the accommodating chamber 71A. A worm gear 82A is fixed to the rotating shaft of the electric motor 81 so as to be integrally rotatable. The electric motor 81 is electrically connected to one end side of elongated metal thin plate terminals 91 and 92 disposed in the accommodating chamber 71A. The other ends of the terminals 91 and 92 are input / output terminals 91A and 92A protruding into the connector 71E. The electric motor 81 is supplied with power from the external controller 3 via the wire harness 4 and the terminals 91 and 92.

  The switching means 50 is accommodated on the right side of the accommodating chamber 71 </ b> A, and includes a switching lever 51 and a gear mechanism 82.

  The 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 51A is inserted through a swing shaft 72C that protrudes from the inside of the first case 71 toward the front (front side in FIG. 2). Therefore, the switching lever 51 can swing around the swing shaft 72C. FIG. 2 shows the switching lever 51 in the initial state. FIG. 3 shows the switching lever 51 in the maximum swing state.

  As shown in FIG. 2, the contact portion 51B protrudes below the contact portion opening 72D formed on the lower surface side of the first case 71 and the second case 72 and extends to the left side of the contacted portion 12B. Exist.

  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 accommodating chamber 71A. The small-diameter gear 82C positioned at the front and the worm wheel 82B positioned at the rear (back side in FIG. 2) are coaxial, and are integrally formed by injection molding of a thermoplastic resin, cutting of a metal material, or the like. The small diameter gear 82 </ b> C and the worm wheel 82 </ b> B are rotatably supported by a rotating shaft 75 that protrudes forward from the inside of the first case 71. The small diameter gear 82C meshes with the sector gear 82D. On the other hand, the worm wheel 82B meshes with the worm gear 82A.

  A return spring 83 is disposed on the rear surface side of the worm wheel 82B. One end of the return spring 83 is locked to a first case side locking portion 83A that protrudes from the first case 71 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 protruding from the rear surface side of the worm wheel 82B toward the first case 71. For this reason, the worm wheel 82B is urged to rotate in the clockwise direction by the return spring 83.

  A gear mechanism 82 is configured including a worm gear 82A, a worm wheel 82B, a small-diameter gear 82C, a sector gear 82D, and a return spring 83. The electric motor 81 and the gear mechanism 82 reciprocate the switching lever 51 between an initial state (see FIG. 2) and a maximum swing state (see FIG. 3), as will be described later.

  As shown in FIG. 1, a handle 8 for opening or locking / unlocking the tailgate 9 is provided above the locking device 1 in the tailgate 9 so as to be exposed to the outside. The front of the handle 8 extends inside the tailgate 9 and is rotatably supported by a support member (not shown) provided inside the tailgate 9. The front end of the handle 8 is connected to the upper end of a connecting member 6 formed by bending a metal bar. The connecting member 6 extends downward toward the second case 72. 2 and 5, the handle 8 is schematically illustrated, but the relative positional relationship between the lock device 1 and the handle 8 is exactly as shown in FIG.

  As shown in FIGS. 1, 2, and 4, the transmission member 100 is a cylindrical shaft body, and is rotatably supported by the second case 72 while being inserted into the accommodation chamber 71 </ b> A from the front side of the second case 72. Has been. At the front end of the transmission member 100 that protrudes to the front side of the second case 72, an elongated plate-shaped input portion 101 is formed. The input part 101 protrudes away from the transmission member 100 to the right, and the lower end side of the connecting member 6 is connected to the tip part (in FIG. 2, the input part 101 is located on the front side of the page). ing). On the other hand, an elongated plate-shaped output portion 102 is formed at the rear end of the transmission member 100 protruding into the accommodating chamber 71A. The output part 102 protrudes away from the transmission member 100 to the left.

  The two-way operation type lever switch 88 is a non-waterproof inexpensive standard product, and is disposed on the upper left side of the accommodating chamber 71 </ b> A so as to be adjacent to the output unit 102. As shown in FIG. 2, the two-way operation type lever switch 88 is electrically connected to one end side of terminals 95, 96, and 97 made of an elongated metal thin plate disposed in the accommodating chamber 71A. The other ends of the terminals 95, 96, 97 are input / output terminals 95A, 96A, 97A protruding into the connector 71E.

  When the handle 8 is in the initial position (the position shown in FIGS. 1, 2, and 4), the fork-shaped portion at the tip of the output unit 102 holds the lever 88A in the neutral position with the tip of the lever 88A interposed therebetween. Thus, the two-way operation type lever switch 88 is in a state where the terminals 95, 96, and 97 are not conducted.

  Then, when the user pushes up the handle 8 as shown in FIG. 5 and opens the tailgate 9, the connecting member 6 is lowered, and the input unit 101, the transmission member 100, and the output unit 102 are rotated counterclockwise. When the output portion 102 pushes up the lever 88A, the two-way operation type lever switch 88 is switched to a state in which the terminals 95 and 96 are made conductive. The position of the handle 8 shown in FIG. 5 is the “first position” of the present invention.

  Further, when the user pushes down the handle 8 as shown in FIG. 6 and performs the locking / unlocking operation of the tailgate 9, the connecting member 6 rises, and the input unit 101, the transmission member 100, and the output unit 102 are connected to each other. When the output portion 102 pushes down the lever 88A, the two-way operation lever switch 88 switches to a state in which the terminals 96 and 97 are electrically connected. As a result, the two-way operation type lever switch 88 transmits to the external controller 3 that the terminals 96 and 97 are in a conductive state via the wire harness 4. The position of the handle 8 shown in FIG. 6 is the “second position” of the present invention.

  On the other hand, a micro switch 89 is disposed below the accommodating chamber 71A and above the curved portion 11D of the fork 11. As shown in FIG. 2, the microswitch 89 is electrically connected to one end side of terminals 93 and 94 made of elongated thin metal plates disposed in the accommodating chamber 71A. The other ends of the terminals 93 and 94 are input / output terminals 93A and 94A protruding into the connector 71E.

  When the fork 11 is in the state shown in FIG. 2, the bending portion 11 </ b> D is pushing the lever 89 </ b> A, and the microswitch 89 is in a state of conducting the terminals 93 and 94. As shown in FIG. 3, when the fork 11 swings counterclockwise around the swing shaft 14A, the lever 89A moves away from the curved portion 11D, so that the microswitch 89 does not conduct the terminals 93 and 94. Switch to As a result, the micro switch 89 transmits to the external controller 3 that the terminals 93 and 94 are not conducted through the wire harness 4.

  In the locking device 1 of the embodiment having such a configuration, when the handle 8 is in the initial position shown in FIGS. 1, 2, and 4, the user attempts to open the tailgate 9 by opening the handle 8. In this case, the switching means 50 automatically operates the lock device main body 70 to bring the tailgate 9 into an unlatched state as described below.

  First, when the user tries to open the tailgate 9 and pushes up the handle 8 to the first position shown in FIG. 5, the operation is performed via the connecting member 6, the input unit 101, and the transmission member 100 as described above. 102, and the output unit 102 pushes up the lever 88A. As a result, the two-way operation lever switch 88 switches to a state in which the terminals 95 and 96 are conducted, and the information is transmitted to the controller 3 via the wire harness 4.

  In response to this, the controller 3 starts control of the locking device 1. Specifically, electric power is supplied to the electric motor 81 through the wire harness 4 and the terminals 91 and 92 to rotate the worm gear 82A. As a result, the worm wheel 82B meshing with the worm gear 82A rotates counterclockwise, and the small-diameter gear 82C also rotates counterclockwise integrally with the worm wheel 82B. Then, as shown in FIG. 3, the switching lever 51 swings clockwise around the swing shaft 72C via the sector gear 82D that meshes with the small-diameter gear 82C, and the contact portion 51B and the contacted portion 12B are moved. Via the pole 12.

  As a result, as described above, the pole 12 opens the fork 11, and the fork 11 swings counterclockwise around the swing shaft 14A. As a result, the fork 11 is switched to a state where the striker 79 is not locked in the entrance 78, and the tailgate 9 is brought into an unlatched state.

  At this time, if the microswitch 89 is switched to a state in which the terminals 93 and 94 are not conducted due to the counterclockwise swing of the fork 11, the information is transmitted to the controller 3 via the wire harness 4. As a result, the controller 3 can determine that the tailgate 9 is in an unlatched state.

  When the user returns the handle 8 to the initial position shown in FIGS. 1, 2, and 4, the operation is transmitted to the output unit 102 via the connecting member 6, the input unit 101, and the transmission member 100, and the output unit 102. Returns the lever 88A to the neutral position. As a result, the two-way operation lever switch 88 returns to a state where the terminals 95, 96, 97 are not conducted, and the information is transmitted to the controller 3 via the wire harness 4.

  In response to this, the controller 3 stops the supply of electric power to the electric motor 81. Accordingly, the switching lever 51 is driven by the worm wheel 82B and the small-diameter gear 82C urged clockwise by the return spring 83, and swings in the reverse direction from the maximum swing state shown in FIG. Returns to the initial state shown in. For this reason, the pole 12 also swings in the opposite direction, and the stopper portion 12A is urged against the outer peripheral surface of the fork 11, so that the fork 11 can be fixed at any time. Thereafter, if the user attempts to close the tailgate 9, the striker 79 enters the advance entrance 78 and swings the fork 11 in the reverse direction, so that the fork 11 and the pole 12 operate in the reverse manner. When the striker 79 enters the bottom of the entrance 78, the state returns to the latched state shown in FIG.

  At this time, when the micro switch 89 is switched to a state in which the terminals 93 and 94 are made conductive by the clockwise swing of the fork 11, the information is transmitted to the controller 3 via the wire harness 4. As a result, the controller 3 can determine that the tailgate 9 is in a latched state.

  Further, when the user tries to switch the tailgate 9 from the unlocked state to the locked state (in the case of the key lock state), when the handle 8 is pushed down to the second position shown in FIG. Is transmitted to the output unit 102 via the connecting member 6, the input unit 101, and the transmission member 100, and the output unit 102 pushes down the lever 88A. As a result, the two-way operation lever switch 88 switches to a state in which the terminals 96 and 97 are made conductive, and the information is transmitted to the controller 3 through the wire harness 4.

  In response to this, the controller 3 prohibits the supply of electric power to the electric motor 81 until the user performs a key lock releasing operation using a well-known remote control key or key. In this state, even if the user tries to open the tailgate 9 and pushes up the handle 8 to the first position shown in FIG. 5, the latched state of the tailgate 9 is maintained. Thereafter, the controller 3 switches the tailgate 9 from the locked state to the unlocked state when the user performs a key lock releasing operation using a well-known remote control key or key. Then, the tailgate 9 can be opened again by the user's opening operation of the handle 8. When the controller 3 senses the presence of the key wirelessly or in a non-contact manner and can enable / disable the locking / unlocking operation, the user who has the key can handle the handle 8 with reference to FIG.

<Effect>
In the locking device 1 of the first embodiment, the two-way operation type lever switch 88 as a specific mode of the first switch and the second switch of the present invention is provided together with the electric motor 81 in the accommodating chamber 71A having a waterproof configuration. Therefore, it is not necessary to make the two-way operation lever switch 88 waterproof. Further, the electric motor 81 and the two-way operation type lever switch 88 can be connected to the controller 3 via one wire harness 4 by one connector 71E provided in the first case 71 and the second case 72. Therefore, the number of wire harnesses and connectors can be reduced.

  Therefore, the locking device 1 according to the first embodiment can realize a reduction in manufacturing cost.

  Further, when the locking device 1 is mounted on the vehicle, the two-way operation lever switch 88 is assembled in the vicinity of the handle 8 in advance, or the two-way operation lever switch 88 is connected to a wire harness different from the wire harness 4. There is no need to connect to the electric motor 81 or the controller 3 via the controller. For this reason, the lock device 1 can simplify the assembling work and can realize an improvement in productivity.

  Furthermore, it is connected to the manual vehicle opening / closing body locking device, that is, connected to the handle and the key cylinder via separate links, and operates using the force by which the user operates the handle or the key cylinder without using a switch. With respect to a vehicle that employs a locking device, the locking device 1 according to the first embodiment that is an electric motor drive type can be easily retrofitted with a minimum specification change. Specific examples of the minimum specification change include the following configurations. That is, the handle is the handle 8 of the first embodiment, the existing link connected to the handle is replaced with the connecting member 6, and the handle 8 and the lock device 1 are connected by the connecting member 6. On the other hand, the existing key cylinder and the existing link connected to the key cylinder are omitted. When such a configuration is adopted, if the connecting member 6 is manufactured by bending a metal round bar, the optimal length connecting member 6 can be manufactured at a low cost according to the distance between the handle 8 and the locking device 1. . In particular, in this locking device 1, since the operation of switching the latched tailgate 9 to the locked state or the unlocked state can also be realized using the displacement of the handle 8 in the reverse direction (from the initial position to the second position), There is no need to provide a lock / unlock operation part (key cylinder, lock handle or lock knob) separately from the handle. As a result, the manufacturing cost of the vehicle itself can be reduced.

  In addition, the locking device 1 employs an inexpensive two-way operation lever switch 88 as the first switch and the second switch, and the two-way operation lever switch 88 is disconnected by the input unit 101 and the output unit 102 of the transmission member 100. By adopting a structure in contact with each other, it is possible to surely reduce the manufacturing cost.

(Example 2)
As shown in FIGS. 7 and 8 , the locking device 2 of the second embodiment has a configuration in which the connecting member 6 in the locking device 1 of the first embodiment is omitted. Since all other configurations of the second embodiment are the same as those of the first embodiment, the same components are denoted by the same reference numerals, and description thereof is omitted or simplified.

  In the locking device 2 according to the second embodiment, the upper portions of the first case 71 and the second case 72 bulge out toward the handle 8. Accordingly, the accommodating chamber 71A also bulges toward the handle 8, and a two-way operation type lever switch 88 is disposed in the bulging range.

The transmission member 200 is rotatably supported by the first case 71 in a state of being inserted into the accommodation chamber 71 </ b> A from the rear surface side of the first case 71. An elongated plate-shaped input portion 201 is formed at the rear end of the transmission member 200 that protrudes toward the rear surface side of the first case 71. The input part 201 protrudes away from the transmission member 200 to the left, and a cylindrical shaft-shaped engagement shaft part 201A is provided at the tip part so as to protrude rearward (FIG. 7 ). Then, the input unit 201 is located on the back side of the paper surface). On the other hand, an elongated plate-shaped output portion 202 is formed at the front end of the transmission member 200 protruding into the accommodating chamber 71A. The output part 202 protrudes away from the transmission member 200 to the right. When the fork-shaped portion at the tip of the output unit 202 sandwiches the tip of the lever 88A, the output unit 202 holds the lever 88A in the neutral position.

The right end of the handle 8, the engagement fork 8A is provided with projecting bifurcated so as to sandwich the engaging shaft portion 201A. When the handle 8 is in the initial position (the position shown in FIGS. 7 and 8 ), the fork-shaped portion at the tip of the output portion 202 holds the lever 88A in the neutral position with the tip of the lever 88A in between, and the two directions The operation type lever switch 88 is in a state in which the terminals 95, 96 and 97 are not conducted.

  Then, when the user pushes up the handle 8 to the first position (see 8 ′ in FIG. 7) and opens the tailgate 9, the engaging fork 8A pushes down the engaging shaft portion 201A and transmits to the input portion 201. The member 200 and the output unit 202 rotate integrally in the clockwise direction, and the output unit 202 pushes up the lever 88A. As a result, the two-way operation type lever switch 88 is switched to a state in which the terminals 95 and 96 are made conductive.

  Further, when the user pushes down the handle 8 to the second position (see 8 ″ in FIG. 7) and performs the locking / unlocking operation of the tailgate 9, the engaging fork 8A pushes up the engaging shaft portion 201A, and the input portion 201, the transmission member 200, and the output unit 202 rotate integrally counterclockwise, and the output unit 202 pushes down the lever 88A, so that the two-way operation type lever switch 88 conducts the terminals 96 and 97. Switch.

  The locking device 2 according to the second embodiment having such a configuration can achieve the same operational effects as the locking device 1 according to the first embodiment.
