Definitions

  • the invention relates to an electrically actuated lock, in particular for a central locking system of a vehicle, according to the features of the preamble of patent claim 1.
  • Such a lock is known from DE 195 36 611 A1.
  • a lever acting on lock elements which can assume two different positions, is actuated by an actuator. If the lever is in the neutral position, it can then be moved back and forth as desired between the two positions, which can result in an undefined or undesired position of the lever. It can happen, for example, that the central locking system is to be brought into the anti-theft position by means of the lever; however, if the lever is in a position that corresponds to the unlocking, the vehicle is not secured so that it is freely accessible to everyone. It goes without saying that such a situation is undesirable and therefore disadvantageous.
  • an actuating cylinder according to DE 195 36 611 A1 has the disadvantage that it takes up a large amount of installation space, which is not available in particular in a door of the vehicle in the installation area of the lock between the outer skin of the vehicle and the inner lining or a pane .
  • the invention is therefore based on the object of improving an electrically actuated lock in such a way that it avoids the disadvantages mentioned above.
  • the lever can be fixed in its positions, which can be adjusted by means of the electric actuator.
  • the actuator is used to "switch" the lever from one to the other and possibly to other positions. This ensures that the lever remains in the respective position, which is specified by the actuator.
  • the actuator switches the lever from one position to the other and then the actuator returns to its initial position, so that the desired position of the lever is maintained, but at the same time the lifting! is decoupled from the actuator so that it can then be moved from the set position to the other position in the event of a fault (in particular failure of the power supply for the actuator), for example by means of a locking cylinder which acts on the lever.
  • a fault in particular failure of the power supply for the actuator
  • a spring is assigned to the lever, with which the lever can be fixed in its positions.
  • This spring is in particular a snap spring, an advantageous embodiment being shown in the figures to be explained.
  • a transmission element is assigned between the actuator and the lever.
  • the actuator such as an electromagnet with a plunger acts directly on the lever and moves it from one position to the other.
  • a transmission element is advantageously arranged between the actuator and the lever, which causes a reduction of the movement of the actuator on the lever. This ensures, on the one hand, the compact design of the actuator and, on the other hand, due to the reduction, the application of the force required to adjust the lever is ensured.
  • the transmission element is designed as a drive disk. While the configuration of the transmission element as an actuating cylinder, as is known from the prior art, is also conceivable, the transmission element is advantageously designed as a flat drive disk which, due to its flat configuration, particularly advantageously the available space between the outer skin of the vehicle and the inner wall (for example, a window on a side door or the interior trim).
  • the drive pulley according to the invention is specified in the further subclaims and shown in the figures still to be explained.
  • An embodiment of the invention provides that a function in the door, the tailgate or the like of the vehicle is realized by means of an actuator and a lever.
  • One actuator act on a lever the lever is then assigned to a handle (such as outside door handle or inside door handle).
  • a handle such as outside door handle or inside door handle.
  • an actuator acts on a transmission element, the transmission element being connected to two levers, the one of the two levers being operatively connected to the outer door handle and the other of the two levers being connected to the stage handle.
  • the transmission element is designed such that both levers perform the same movement or perform different movements when the actuator is actuated.
  • a handle it is conceivable for a handle to have its own actuator with associated transmission element and associated lever. This makes it possible to set the positions of the lever not only via the design (contours) of the transmission element, but also via appropriate control of the respective steep drive.
  • the actuator is designed as an electric motor, since such an electric motor is inexpensive to manufacture, reliable is in its function and by means of which a reduction of the movement of the electric motor onto the transmission element can be realized in a simple manner.
  • the actuator in general, in particular the electric motor, can be switched off depending on the switch signal either when the lever has reached its respective other position, which is detected by means of a switch or the like, it also being conceivable to operate the actuator in block mode, This means that the stroke of the actuator or the lever is limited at the end of a respective position, whereby after reaching the other position, the actuator is switched off after a predetermined time, which is sufficient to safely reach this position, or the power consumption or a other parameters of the actuator is measured and, if this parameter changes suddenly, the actuator is switched off.
  • Figure 1 a lock with an actuator
  • FIG. 2 a spring assigned to the lever
  • FIG. 6 a lock according to the invention with two actuators
  • Figures 7 to 10 different positions of the levers.
  • Figure 1 shows an electrically actuated lock with an actuator, which is designed as an electric motor 1.
  • a worm wheel 3 is seated on a shaft 2 of the electric motor 1, one of the electric motor 1 serving as a drive disc 4 trained transmission element is driven.
  • An outer periphery 5 of the drive pulley 4 is provided with teeth (not shown in FIG. 1) which mesh with the worm wheel 3 and thus form a reduction gear.
  • At least one side of the drive pulley 4 has inner elevations 6 and outer elevations 7, which form an intermediate region.
  • the inner and outer elevations 6, 7 form a contour for setting various functions of the lock, as will be described later.
  • the drive pulley 4 is rotatably mounted on a shaft 9.
  • Reference number 10 denotes a first lever, the end of which the drive pulley 4 is associated carries a pin 11 which projects into the intermediate region 8 and can come into contact with the contours of the inner elevations 6 and outer elevations 7. Furthermore, a second lever 12 is shown in FIG. 1, which is mounted with the first lever 10 on a common shaft 13 and can be adjusted independently of the first lever 10 by means of internal elevations and external elevations on the other side of the drive pulley 4. At this point it should be mentioned that with the embodiment shown in Figure 1, the actuation of the inside door handle and the outside door handle can be transferred to lock elements such as pawl / rotary latch depending on the positions of the levers 10 and 12.
  • a separate handle such as an inside door handle
  • a separate handle such as an inside door handle
  • its own electric motor 1 with its own drive pulley 4 and internal elevations 6 and external elevations 7 on only one side and also only a single lever. Since the design of the lock elements does not affect the design of the actuator, an illustration has been omitted.
  • a handle is connected to a further lever via Bowden cables, this further lever being operable, for example, by the first lever 10.
  • the further lever acts on lock elements, such as on the pawl interacting with a rotary latch.
  • FIG. 2 shows a spring 14 assigned to the lever 10 (or the lever 12), by means of which the lever 10 and / or the lever 12 can be fixed.
  • the lever 10 In the position of the lever 10 shown with solid lines, for example, the unlocking position of the lock is designated, while with a rotary movement about the common shaft 13 the lever 10 assumes its second position, which corresponds to the locking position, and can be fixed by means of the spring 14.
  • the definition of a lever by means of a spring is not a limitation, so that other means of determining a lever can also be considered.
  • FIG. 3 shows, for example, the starting position in which the two levers 10, 12 are in the same position, which corresponds, for example, to the unlocking position.
  • the drive pulley 4 is rotated, whereby due to the Exercises 6 and external elevations 7 given contours of the pin 11 slides along this and causes the lever 10 to be moved to its other position.
  • the lever 12 can also be moved with the first lever 10, it being shown in FIG. 4 that when the drive disk 4 rotates, for example by approximately 90 °, the lever 10 is brought into its other position while the second lever 12 is in its starting position remains.
  • Figure 5 shows that with a further rotation of the drive pulley 4, the lever 10 is moved back into its first position, while the lever 12 is moved from its first position to the other position.
  • FIGS. 3 to 5 it is self-evident, even if this is not shown, that means for fixing a lever in one position, such as the spring 14, are present.
  • FIG. 6 it is shown that the function of a single handle is set via an electric motor.
  • the lever 10 is driven by the electric motor 1 via its own drive disk 4.
  • the drive pulley 4 is again with Provide inner elevations and outer elevations, which form an intermediate region in which the pin of the lever 10 engages.
  • the drive pulley 4 is smooth.
  • a second electric motor 15 is now provided, which drives a second drive disk 16 arranged on the shaft 9, the second lever 12 being movable by means of the second drive disk 16.
  • the second drive disk 16 is also flat on one side and also has inner and outer elevations on the other side, between which a pin of the lever 12 engages.
  • the two drive disks 4 and 16 can be driven independently of one another depending on the respective control of the electric motor 1 or 15.
  • This embodiment shown in FIG. 6 in turn allows an extremely flat construction, which enables all functions of an electrically operated lock, such as unlocking, locking and theft protection (possibly also child protection).
  • the lock functions for two handles are realized.
  • levers 10 and 12 can have common (or also different) starting positions (common starting position is shown in FIG. 7), the different positions of the levers 10 and 12 can be adjusted after driving the electric motor 1 or 15 (FIGS. 8 to 10).
  • the intermediate area 8 between the inner elevations 6 and outer elevations 7 is designed such that after the actuator has "shifted” a lever from one position to the other, it is moved to its neutral position, in which it is possible to move the lever to its other position by actuating a lock cylinder.
  • the intermediate area is designed such that a movement of a lever about the common shaft 13 after overcoming the force of the spring 14 allows this "switching". This advantageously provides a decoupling of the lever or the lock elements from the actuator. This is necessary because the actuator acts stepped down on the lever and therefore no force has to be applied to overcome the actuator when the lock cylinder is actuated.
  • the contours of the drive pulley in the embodiment according to FIG. 1 are selected such that the drive pulley 4 has no end position and the actuator must therefore be controlled by a suitable angular range by means of suitable means (for example switches for position detection).
  • the actuator or the actuators are operated in the so-called block mode, so that the drive disk or the drive disks can only rotate through predeterminable angular ranges.
  • the block operation according to FIG. 6 can of course also be transferred to the embodiment according to FIG. 1 and vice versa.
