<Operation 5>
Furthermore, in this lock system 1, as shown in FIG. 17, when the passenger pushes down the front end portion of the child lock lever 12, the rear end portion of the child lock lever 12 moves the slide pin 58 to the transmission portion 53 </ b> J of the lever 53. Make contact. Here, the operation of pushing down the front end of the child lock lever 12 also corresponds to the second operation of the present invention.

  Thereby, the transmission part 53J of the lever 53 interferes with the slide pin 58, and the swing of the lever 53 is transmitted to the lever 52. Thus, the child lock lever 12 enables the passenger to pull the upper end of the inside handle 11 from the vehicle inner side to the rear side.

  At this time, the displacement is transmitted to the second action portion 121 via the tooth portion 12G of the child lock lever 12. For this reason, as shown in FIG. 8, the 2nd action part 121 rocks to the back side. As a result, the second operation unit 125 swings downward, and the movable portion 102M of the child switch 102 swings downward. Therefore, as shown in FIGS. 11 and 12, the movable portion 102M of the child switch 102 connects the second starting point 102A and the lock contact 102C.

  For this reason, the controller detects that the operation of depressing the front end of the child lock lever 12 has been performed when the child switch 102 is turned on, and is used for grasping the state of the slide door 2 and controlling the automatic opening and closing. To do.

  In other words, the displacement of the child lock lever 12 can be detected by the child switch 102.

<Operation 6>
In the lock system 1, as shown in FIG. 2, when the passenger pulls the outside handle 13 from the outside of the vehicle, the rod 13R is pushed down as shown in FIG. Here, the operation of pulling the outside handle 13 corresponds to the third operation of the present invention.

  As a result, the lever 41 swings clockwise toward the paper surface. As a result, the third action part 131 swings forward. Therefore, as shown in FIG. 8, the third operation unit 135 swings downward, and the movable portion 103M of the outside handle switch 103 swings downward. Thereby, as shown in FIGS. 9-12, the movable part 103M of the outside handle switch 103 connects the third starting point 103A and the third contact 103B.

  For this reason, the controller detects that the outside handle 13 has been pulled, and detects an instruction to open the slide door 2. For this reason, an electric slide mechanism (not shown) is operated to automatically open the slide door 2.

<Operation 7>
When the rider stops the operation of pulling the outside handle 13, the rod 13R is raised and the lever 41 swings counterclockwise toward the paper surface as shown in FIGS. As a result, as shown in FIG. 8, the third action part 131 swings rearward. Then, the third operation unit 135 swings upward, and the movable portion 103M of the outside handle switch 103 swings upward. Accordingly, the movable portion 103M of the outside handle switch 103 blocks the third starting point 103A and the third contact 103B.

  That is, the outside handle switch 103 can detect the displacement of the outside handle 13.

<Operation 8>
Further, in the lock system 1, as shown in FIG. 17, when the passenger performs an operation of pushing down the door lock lever 14 from the inside of the vehicle, the lever 57 separates the slide pin 59 from the transmission portion 52 </ b> J of the lever 52. Here, the operation of pushing down the door lock lever 14 corresponds to the fourth operation of the present invention.

  Thus, even when the passenger performs an operation of pulling the outside handle 13 from the outside of the vehicle or an operation of pulling the upper end portion of the inside handle 11 from the inside of the vehicle to the rear side, the transmission portion 52J of the lever 52 is moved with respect to the slide pin 59. The swing of the lever 52 is not transmitted to the lever 51. Thus, the door lock lever 14 invalidates those operations.

  When the passenger performs an automatic locking operation of the slide door 2 using a remote control key or the like, as shown in FIG. 13, the automatic locking mechanism 40 is operated under the control of the controller, and the actuator 40A is moved clockwise toward the paper surface. Rock. Then, the lever 57 also swings, and the slide pin 59 is separated from the transmission portion 52J of the lever 52. Further, the door lock lever 14 is pulled down via the lever 56. As a result, the slide door 2 is automatically locked. Moreover, when the automatic locking mechanism 40 performs the reverse operation, the slide door 2 is automatically unlocked.

<Effect>
In the lock system 1 according to the first embodiment, the handle opening contact 101B of the inside handle switch 101 and the second starting point 102A of the child switch 102 are connected in series, and therefore the inside handle switch is used to detect the displacement of the inside handle 11. Even if the switch 101 is employed and the child switch 102 is employed to detect the displacement of the child lock lever 12, one switch wiring can be omitted.

  In addition, since the lock system 1 employs the link mechanism 3, a degree of freedom is obtained in the location of the inside handle switch 101, the child switch 102, and the outside handle switch 103.

  In the lock system 1, the inside handle switch 101, the child switch 102, and the outside handle switch 103 are housed in the housing chamber 191 of the housing 190.

  The inside handle switch 101 is connected / disconnected by a first transmission part 110 having a first action part 111 provided outside the housing 190 and a first action part 115 provided in the accommodation chamber 191. The displacement of is detected.

  The child switch 102 is connected and disconnected by a second transmission part 120 having a second action part 121 provided outside the housing 190 and a second operation part 125 provided in the storage chamber 191, and the child lock lever 12 is connected. The displacement of is detected.

  Further, the outside handle switch 103 is connected and disconnected by a third transmission part 130 having a third action part 131 provided outside the housing 190 and a third action part 135 provided in the storage chamber 191. The displacement of the handle 13 is detected.

  The other end 180P of the switch wiring 180, the switch wiring 181 and the switch wiring 182 are connected to the inside handle switch 101. In addition, a switch wiring 182, a switch wiring 183, and a switch wiring 184 are connected to the child switch 102. Further, the other end 180Q of the switch wiring 180 and the switch wiring 185 are connected to the outside handle switch 103. The switch wiring 180, the switch wiring 181, the switch wiring 183, the switch wiring 184, and the switch wiring 185 are collected in the accommodation chamber 191 by the connector 170. When the connector 170 is connected to the mating connector 179 outside the housing 190, the inside handle switch 101, the child switch 102 and the outside handle switch 103 are electrically connected to the outside.

  For this reason, the inside handle switch 101, the child switch 102, the outside handle 103, and the housing 190 constitute the switch module 100. For this reason, the assembly work is completed simply by assembling the housing 190 of the switch module 100 to the lock system 1 and connecting the mating connector 179 to the connector 170. For this reason, the assembly | attachment operation | work of the inside handle switch 101, the child switch 102, the outside handle 103, and switch wiring 180-185 with respect to the lock system 1 can be simplified. Further, when the lock system 1 is assembled to the vehicle, the inside handle switch 101, the child switch 102, the outside handle 103, and the switch wires 180 to 185 in the storage chamber 191 do not come into contact with other members. The switch 102 and the outside handle 103 are not easily damaged, and they are not easily disconnected.

  In particular, since the housing 190 waterproofs the interior of the storage chamber 191, inexpensive switches that are not waterproof specifications can be used as the inside handle switch 101, the child switch 102, and the outside handle 103, so that the manufacturing cost can be reduced.

  Therefore, according to the lock system 1, simplification of assembly work and reduction in manufacturing cost can be realized.
