Definitions

  • the invention relates to an electromotive actuator with a limit switch.
  • Actuators are used for various mechanical actuations, in which an electrical pulse is supplied to a lifting magnet, the armature of which performs the required movement for a short time.
  • Electromotive actuators in which the drive motor is switched off with the help of switches provided when one or both end positions are reached, are often provided, in particular for longer travel ranges. Such switches, which are to be installed in addition to the motor and a transmission in such electromotive actuators, make the actuators more expensive.
  • the object of the invention is therefore to provide a cost-effective way to limit the shutdown of an electromotive actuator.
  • the electromotive actuator according to the invention has the advantage that it is particularly inexpensive to manufacture.
  • a further development of the invention is that one of the conductor tracks has a longer and a shorter section, which are electrically separated from one another. This further development provides a favorable possibility not only to switch off the motor when it reaches its end position, but also to short-circuit it for braking purposes.
  • sliding contacts are arranged on a sheet metal part designed as a leaf spring, which comprises the flattened shaft of the wheel and rests on the wheel with surfaces lying between the sliding contacts.
  • This development represents a particularly simple form of sliding contacts, which in particular contributes to the inexpensive assembly of the actuator according to the invention.
  • a preferred application of an electromotive actuator consists in the zero position of a daily distance counter for motor vehicles and is characterized in that a wheel driven by a motor has an eccentric, which is in operative connection with the zeroing element of the daily distance counter, that a switch is provided which disconnects the motor from a voltage source at a given position of the wheel and that the switch can be bridged with the normally open contact of a pushbutton switch.
  • Embodiments of the invention deal with the design of the eccentric and that the switch is designed as a short-circuit brake.
  • a motor 1 drives a wheel, also not shown, via a gear, not shown, which is provided with a contact device 2.
  • the contact device 2 has two sliding contacts and connects an inner slip ring 3 to an outer slip ring 4 or 5. Details of the configuration of the contact device 2 are explained in connection with FIG. 2.
  • the outer slip ring is divided into a longer section 4 and a shorter section 5.
  • the slip rings are arranged as conductor tracks on an insulating plate. They can therefore be manufactured in an extremely inexpensive manner using known methods for producing printed circuits. They are preferably made of copper and are coated with a more noble metal to prevent oxidation.
  • the invention is not limited to the concentric arrangement of the slip rings shown.
  • slip rings could also be used, which are arranged side by side on the lateral surface of a cylinder.
  • the contact device 2 connects the inner slip ring 3 with the section 5 of the outer slip ring and thus shorts the motor 1 via the lines 6, 7 and 8 and the normally closed contact 9 of a pushbutton switch 10.
  • the longer section 4 of the outer slip ring is connected to the one pole 11 of a voltage source, not shown.
  • the motor is connected to the inner slip ring and to the other pole 12 of the voltage source.
  • FIG. 2 shows a longitudinal section through a second exemplary embodiment, in which the motor 1 and the further movable parts are mounted in a housing 15.
  • a worm 17, which engages in a worm wheel 18, is arranged on the motor shaft 16.
  • the plunger 21 is guided in the housing part 22 and is connected to the zeroing element of a daily distance counter. The latter is known per se and need not be explained in connection with the invention.
  • a connector plug 23 is provided for the electrical connections to the voltage source and to the pushbutton switch 10 (FIG. 1).
  • a contact spring 25 is attached to the flattened shaft 24 of the worm wheel 18, which is shown enlarged in FIG. 2a for the sake of clarity.
  • a cutout in the contact spring shaped in accordance with the cross section of the axis 24 secures the contact spring 25 against rotation relative to the worm wheel 18 and the eccentric 19. With the surfaces 26 and 27, the contact spring 25 rests on the surface of the eccentric 19.
  • the parts 28 and 29 of the contact spring 25 are bent away from the surface of the eccentric 19 and carry the sliding contacts 30 and 31, which are arranged at different distances from the axis according to the radii of the slip rings.
  • the sliding contacts 30 and 31 touch with appropriate pressure circular conductor tracks, which in FIG. 2 are not shown for the sake of clarity, but correspond to those shown in FIG. 1.
  • the third embodiment is shown in Fig. 3 as a cross section.
  • a motor 1 drives a worm wheel 18 via a worm 17.
  • the shaft 33 of the worm wheel 18 is formed on one side by a corresponding increase in the diameter and arrangement of a pin 34 as a crank.
  • Sliding contacts 35, 36 are arranged on a correspondingly designed contact spring 37 on the other side of the worm wheel 18.
  • both contacts are arranged on the same side of the shaft 33.
  • this is irrelevant to the function of the invention, since the inner slip ring comprises a full circle.
  • the position of the grinder 36 is therefore arbitrary.
  • the housing 38 also shows a housing 38 and a printed circuit board 14 which carries the conductor tracks 3 and 4 and 5, respectively.
  • the housing 38 comprises a run-up bead 39 which causes the worm wheel 18 to be guided in the axial direction.
