【Example】

Embodiments of the present invention will be described based on the drawings. Figure 1 shows the installation in the partition part of the vehicle compartment. FIG. 2 is a schematic layout diagram of an automatic door locking device. The partition 1 has an opening 2. The automatic door 3 that opens and closes the opening 2 is suspended from a rail 4 installed on the ceiling of the vehicle compartment. be supported. The automatic door 3 is a door that closes the opening 2 by an opening/closing motor (not shown). It moves between a closed position and a fully open position where it retreats into the door pocket 5. Door bag 5 side of automatic door 3 A locking motor 6 is disposed at the side end 3a of the It is transmitted to the rotating shaft 7 by a arm gear mechanism. A link 8 is fitted onto the rotating shaft 7. So The link 8 is placed in a locked position with the tip of the link located diagonally to the upper right, and in the locked position. The lock position stop detection limit is set so that it stops at the retracted position rotated 180° from the position. switch Sw1 and evacuation position detection limit switch Sw2 (see Figure 2 for both). to control the locking motor 6.

[0007] A pivot shaft 9 is provided at the entrance of the door pocket 5 to pivot a cocoon-shaped lock lever 10. The lock lever 10 rotates to the lock position when the automatic door 3 reaches the fully closed position. The retaining spring 11 is placed above the pivot shaft 9 in a clockwise direction. energizes the rotational force to. Additionally, 12 is a stopper that restricts the clockwise rotation. , 13 are switches for detecting movement of the automatic door 3 to the closed position.

[0008] FIG. 2 schematically shows a control circuit for the locking motor 6. As shown in FIG. The control cycle The circuit consists of two AND circuits 14, 15, one OR circuit 16, and a lock motor drive. It is composed of a circuit 17. The AND circuit 14 is connected to the switch 13 and the lock position is stopped. Connect the detection limit switch Sw1. In addition, the AND circuit 15 is connected to the switch. 13 and the evacuation position detection limit switch Sw2. And AND circuit 1 4 and the AND circuit 15 are connected to the OR circuit 16. Locked by the output of OR circuit 16. The opening/closing of a motor drive switch 18 interposed in a motor drive circuit 17 is controlled.

[0009] Regarding the operation of the automatic door lock device with the above configuration, the operation explanatory diagram in Fig. 3 and Fig. 4 This will be explained with reference to the time chart. When the automatic door 3 moves to the closed position, the Switch 13 is turned on. At this time, the link 8 is in the retracted position as shown in Figure 3(a). Since it is moving, the lock position detection limit switch Sw1 is turned off. There is. Therefore, the logical product of the AND circuit 15 is established and the output from the OR circuit 16 Close the motor drive switch 18, drive the locking motor 6, and move the link 8 as shown in FIG.

0010 When opening the automatic door 3, power is applied to the locking motor 5 again, as shown in Fig. 3(c). The link 8 rotates clockwise so that the lock lever 10 is held by the holding spring 11. The lock lever 1 is removed counterclockwise against the elastic force and stopped at the retracted position. The automatic door 3 is unlocked by 0. Also, it resists the spring elasticity of the holding spring 11. You can also manually move the automatic door in the opening direction. In this case, the switch Since both the switch 13 and the retraction position detection limit switch Sw2 are turned off, the AN The logical product of the D circuit 14 is established, the locking motor 6 is automatically driven, and the link 8 is activated. Rotate from the lock position to the retracted position (see Figure 4).

[0011] In addition, as shown in the dotted circle in FIG. The spring 11 and the stopper 12 can be arranged horizontally and vertically inverted from the above case. Therefore, one locking motor 6 can lock the automatic door 3 not only in the closed position but also in the open position. Can be locked. In this open position, the link 8 is in the locked position in the closed position. The retracted position becomes the retracted position, and the retracted position becomes the lock position. Also, two lock motors 6 will be used, but the lock motor 6 is connected to the door pocket 5. Alternatively, the lock lever 10 may be provided on the automatic door 3.
