Definitions

  • An electromotive actuator with actuator disk o.
  • the like As actuator element has proven to be compact and reliable. He is in such a motor vehicle lock regularly with an operating lever system and a locking lever system.
  • the operating lever system has an outside operating lever and an inside operating lever. In this case, usually the external operating lever is connected to an outside door handle, while the inside operating lever is connected to a door inside handle.
  • the locking lever system regularly has at least one inside locking lever. This is either carried out separately, for example, leading to the réelleverriegelungsknöpfchen, but can also be integrated with the internal operating lever.
  • On the front side doors of a motor vehicle and on the rear door of a combi vehicle there is also an outer locking lever, which is in communication with a lock cylinder and / or a remote control device.
  • the locking lever system of a motor vehicle lock is switched back and forth between the functional states “unlocked”, “locked” and “locked-theft-secured” by means of the electromotive actuator. It is provided regularly and even at the starting point forming state of the art that the lever of the actuator at least in an end position of the actuator disc and manually between the functional states “unlocked” and “locked” back and forth switchable. However, if the actuator is in the functional state "locked-theft-protected", the shift lever is blocked in the state of the art by means of the anti-theft lever in the functional state "locked”.
  • the starting point forming electromotive actuator for a motor vehicle lock while a manual unlocking in case of failure of the central locking drive can be easily, reliably and quickly effected.
  • a mechanical emergency operation is no longer possible at spring break of the biasing spring for the anti-theft lever.
  • the arrangement of the actuator disk, the shift lever and the liftable pawl is in the above-described electric motor actuator also such that the pawl in the functional state "anti-theft" may have to absorb very high forces.
  • This high application of force to the pawl is structurally difficult to implement. Only with very high quality materials, which are then expensive, can be achieved.
  • Kinematically, the arrangement taken has the disadvantage that the directions of rotation of the actuator disk for the overturning of the shift lever are not unique. Due to the construction with latch and preload spring on the anti-theft lever it is necessary that the shift lever is overturned once in clockwise rotation, another time in left rotation in one and the same function state, so for example "unlocked” or "locked”. Which direction of rotation is required is also determined by the respective position of the pawl. Therefore, a very intelligent, powerful electronic control is required, which again causes considerable costs.
  • the invention is based on the problem to improve an electric motor actuator of the type in question in terms of design, taking into account the requirements of the mechanical emergency operation.
  • the anti-theft lever is controlled independently by the actuator disk, that is, not in connection with the shift lever.
  • this control is such that the anti-theft lever biased by the biasing spring in the direction of the functional state "anti-theft", ie from the functional state "not theft-proofed” in the functional state "theft-proof” is switchable. If the pretensioning spring breaks, then the antitheft lever either remains in the functional state "not theft-proof” or, in any case, can be switched to this functional state mechanically by means of the emergency-actuation function.
  • an additional pawl is omitted, because the anti-theft lever is durable by a control link on the actuator disk in the functional state "not theft-proof".
  • Figs. 1 and 2 of the drawing show in connection the basic structure of the preferred embodiment of an electromotive actuator for a motor vehicle lock, which is shown here.
  • a motor vehicle lock is designed for "unlocked”, “locked” and “locked-theft-protected” functional states, that is to say that an actuating lever system of the motor vehicle lock enters these functional states can be switched by means of the electric motor actuator and mechanically-manually and in particular by means of an emergency operation function.
  • the illustrated electromotive actuator for a motor vehicle lock initially includes a housing 1, which is here open on one side, so that you can look into it.
  • This housing 1 initially houses a reversible drive motor 2 and a drive pulley 4 rotatably driven in the illustrated embodiment by the drive motor 2 via a spindle 3.
  • an actuator element is present and, preferably, the rotatably driven Stellantriebsscale 4. In principle, but would also be a linearly adjusted Actuator element conceivable. Important is the interaction of the actuator disk 4 with the locking lever system.
  • the shift lever 5 is at least in one end position of the actuator disk 4 manually between the functional states "unlocked” and locked switched back and forth, so that even in case of failure of the electric motor drive manual unlocking and locking the motor vehicle lock is possible.
  • FIG. 3 and 4 show the functional state "locked”.
  • Fig. 5 is similar to Fig. 4 and shows the functional state "anti-theft" of the anti-theft lever 7. In this functional state keeps the anti-theft lever 7 in the functional state “locked” standing shift lever 5 in its functional state "locked” firmly.
  • an actuating lug 8 This can be used in assembled motor vehicle lock a mechanical emergency actuator, in particular a key-operated external locking lever of the locking lever system attack. (Arrow direction in Fig. 5).
  • Notbet Ober Incs institutes the anti-theft lever 7 at i. w. unchanged in the functional state "locked-theft-proof” standing actuator disc 4 overcoming a detent 9 o. The like.
  • Mechanically-manually in the functional state "not theft-proof” brought. This functional state is shown in FIG. 6 of the drawing.
  • the anti-theft lever 7 by means of the biasing spring 7a from the functional state “not theft-proof” (Fig. 2 and Fig. 4) in the functional state “anti-theft” (Fig. 5) is switchable.
  • Fig. 2 and Fig. 4 further show that the anti-theft lever 7 is held here by a control link 11 on the actuator disk 4 in the functional state "not theft-proof”.
  • the anti-theft lever 7 is also held by the "unlocked” in the functional state switching lever 5 in the functional state "not theft-proof”.
  • the dargberry embodiment shows in particular in Fig. 2, 4, 5 and 6, that the detent 9 is designed here as a one-sided beveled, resilient nose. This is designed as designed in the actuator disk 4 spring tongue.
  • the transition from Fig. 5 to Fig. 6 of the drawing shows how by mechanical attack on the operating lug 8 of the anti-theft lever 7 by means of not shown here Notbetutzs institutes, ie in particular of the key-operated external locking lever in the arrow direction ( Figure 5) of the anti-theft lever 7 under elastic back pressures the detent 9 has been brought from the functional state "theft-proof" back to the functional state "not theft-proof".
  • Fig. 5 shows the functional state "locked-theft-secured".
  • the anti-theft lever 7 blocks with a stop 13, which is in front of an edge 14 of the shift lever 5 in its position shown in Fig. 3, a movement of the shift lever 5 in the functional state "unlocked”, ie back to the position in Fig. 1st ,
  • the illustrated embodiment is further characterized by a particularly simple design of the control link 11. This is simply done as a raised edge on the actuator disk 4. This is provided with an opening 15, where the anti-theft lever 7 can swivel under the action of the biasing spring 7a in the inner region of the actuator disk 4 and the functional state "anti-theft", shown in Fig. 5, reach. In this functional state of the anti-theft lever 7 is then behind the nose of the detent 9, but, as already explained above, can be "run over" in the context of emergency operation.
  • the anti-theft lever 7 is designed here as a two-armed lever with the operating lug 8 on the second lever arm.
  • an electric motor actuator is further characterized in that the actuator disk 4 and the anti-theft lever 7 are made of plastic material.
  • the forces involved are to be dimensioned in this construction so that the use of plastic material, possibly also fiber-reinforced, completely sufficient, if appropriate material thicknesses provides.
  • plastic material possibly also fiber-reinforced, completely sufficient, if appropriate material thicknesses provides.
  • other materials can be used, especially metals such as aluminum. Accordingly, metal, for example aluminum, is recommended as a material for the shift lever 5, which is subjected to higher forces.
  • Fig. 2 also shows that in the illustrated and preferred embodiment, the shift lever 5, a microswitch 16 is associated.
  • This microswitch 16 allows the control technically correct start of the functional state "locked”. After actuation of the microswitch 16, the electric drive motor 2 by means of a short-circuit braking o. The like. At a small angular distance comes to a standstill.
  • the illustrated embodiment also shows that the micro-switch 16 is actuated here via a switch actuating lever 17. This allows a suitable power transmission from the shift lever 5 to the microswitch 16.
  • FIGS. 1 and 3 show the arrangement and function of the microswitch 16 with the switch operating lever 17 particularly well. The microswitch is actuated in FIG. 1, the functional state “unlocked”, in FIG. 3, the functional state "locked” is not actuated. The switch operating lever 17 is thereby moved by the shift lever 5 in the manner shown.
  • the switch operating lever 17 is made of plastic material here, because also the switch operating lever 17 not too large forces loads is exposed. Not recognizable in the drawing, because that is concealed in the lower level, the design of the arrangement such that the micro-switch 16 - via the switch operating lever 17 - not only from the shift lever 5, but also from a Betreliistsg Techselement on the actuator disk 4, namely a partially circular arranged in the lower level on the actuator disk 4 backdrop can be actuated.
