  • One end of the output lever (output section) 9 is fixed to the other end of the output shaft 6 so as not to rotate with respect to the output shaft 6. Therefore, the output pin 19 rotates together with the inner pin 15 within the rotation range regulated by the cushions 81 and 802.

  • FIG. 22 shows the same state as FIG. 20, that is, the state in which the door lock main body DL is locked by the inner lever 5 via the output lever 9. From this state, when the small motor 1 is energized and the mechanical gear 3 is rotated in the direction of arrow C (unlocking direction), as shown in FIG. 0 2 comes into contact with one of the protrusions 501 of the inner lever 5, and the rotation force can be transmitted to the inner lever 5 using the protrusion 501. When the rotary gear 3 is further rotated, the state shown in FIG. 24 is reached, and the state shown in FIG. 25 is reached in which the transmission of rotational power by contact with the protruding portion 501 is completed.
  • the inner lock 15 is unlocked by the unlocking operation (including the inertia) of the door lock body DL.
  • the inner lever 5 remains in the cushion even if the gear 3 and the inner gear 5 are separated. It rotates until it comes into contact with the pin 800 (L part).
  • the unlocking side torque which is pressed by the projection 310 of the intermediate reduction gear is applied to the inner lever 5 connected to the door lock body DL.
  • Rotating tongue that has a stopper wall 501 a and a stopper wall 500 b formed at the tip that moves in a substantially arc shape, and that is received from the projection 310 of the intermediate reduction gear.
  • the cushion 802 restricts the movement of the inner lever 15 against the torque, so that the spring 802 moves in the torque transmission path between the pinion 2 and the inner lever 15 to prevent the torque from flowing.
  • the projecting portion 301 of the intermediate reduction gear is temporarily moved in a substantially arc-shaped moving rail of the inner lever 5.
  • the inner lever 5 depresses the cushion 802 while the inner lever 5 presses the cushion 802 while bending the L-shaped part 73 of the spring 7.
  • the elasticity stored in the L-shaped part 703 of the spring 7 causes the projection part 301 of the intermediate reduction gear to move to the inner lever. Since it will be released from within the approximately arc-shaped movement trajectory of 5, the motor 1 will be unlocked by activating it, and after stopping the power supply to the motor 1, the L-shape of the spring 7 will be released.
  • the intermediate reduction gear 3 Since the intermediate reduction gear 3 only slightly rotates due to the elasticity of the part 703, the intermediate reduction gear 3 is rotated by the L-shaped part 703 of the spring 7. The gear noise that sometimes occurs can be reduced. Also, when locking, as in unlocking, after activating Motor 3 to lock and stop energizing Motor 1, the L-shaped part 70 of the spring 7 Occurs when the intermediate reduction gear 3 is rotated by the L-shaped part 70 2 of the spring 7 because the intermediate reduction gear 3 only slightly rotates due to the elasticity of 2. Reduce gear noise You can let them do it.
  • the clutch mechanism can be achieved with only two parts, the inner lever 5 and the spring 7, and can be achieved with low cost.
  • the cushion is formed by abutting the ends of the L-shaped portions 720 and 703 of the spring 7 against the inner wall of the case 10.
  • a curved portion that substitutes for the functions of 801 and 802 is provided.
  • a rubber cushion 12 having the same function is fixed to the inner lever 5, and FIG. As in the example shown, rubber cushions 12 are abutted against the inner wall of case 10 to substitute the functions of cushions 81 and 802. .
  • the rubber cushions 12 shown in FIG. 30 may be connected and integrally formed. Also, instead of substituting the functions of the cushions 81 and 802 for the rubber cushion 12, simply substitute the function of the spring 7. However, it is also possible to adopt a configuration in which the cushions 81 and 802 are not abolished. Industrial applicability
  • the door lock driving device operates the motor, locks or unlocks the motor, stops the power supply to the motor, and then stops the elastic body. This is effective as a door lock drive that can reduce the gear noise generated when rotating the intermediate gear.

Abstract

Came (7) conçue pour tourner lorsque la force de rotation d'un moteur (3) lui est transmise, et qui actionne un levier de commande (8) par l'intermédiaire d'une partie du levier (8a ou 8b) recevant le couple et cesse de tourner quand elle bute sur une paroi butée (8d et 8e) intégrée au levier (8) de manière à ce que ce dernier puisse se placer dans une position de blocage ou de déblocage. Un réducteur intermédiaire (5), servant à transmettre un couple de rotation à la came (7) par l'intermédiaire du ressort (6), continue sa rotation en faisant fléchir le ressort (6) même après l'arrêt de la rotation de la came, et revient doucement à l'arrêt. Quand, à ce moment, l'alimention électrique du moteur (3) se trouve coupée, le réducteur intermédiaire (5) est sollicité dans le sens opposé par l'énergie élastique accumulée dans le ressort (6) de façon à être entraîné dans le sens opposé tandis que la came (7) s'arrête dans une position où elle est libérée de la paroi butée (8d et 8e) placée sur le levier (8).
