Definitions

  • the invention relates to a drive unit for motor vehicle applications, in particular an electromotive opening drive unit as part of a motor vehicle lock, preferably a motor vehicle door lock, with an electromotive drive for actuating an actuating element, and with a manually actuatable manipulation element, which at least in the engaged position with the drive reversing is set up.
  • the drive unit can be a window lift drive, a seat or mirror adjustment, a sliding door drive, a tank locking and unlocking mechanism, a tailgate drive, but it can also be a drive unit, with the help of which, for example, a charging plug for an electric or hybrid vehicle in the Locked compared to a charging socket.
  • the control element has different designs.
  • the control element in a window lift drive may be a cable pull.
  • the adjusting element in a seat or mirror adjustment can be designed as an adjusting pin. If the locking and unlocking of a plug of an electrical charging infrastructure in an electric or hybrid motor vehicle is considered, the actuating element may be designed as a locking pin.
  • electromotive opening drive units are preferably, but not exclusively, considered components of a motor vehicle lock and preferably a motor vehicle door lock.
  • the electric motor drive typically works directly or indirectly on a pawl as an actuating element.
  • the pawl is lifted from its engagement with the rotary latch, for example when the motor vehicle door lock is opened electrically, with the aid of the electric motor drive.
  • the catch can open with spring support.
  • function-related emergencies are also conceivable, at least for opening the locking mechanism.
  • a function-related emergency can occur in practice if, for example, the electric motor drive has failed due to a power failure.
  • Other function-related emergencies arise when the electric motor drive is sluggish or does not meet its required functionality as a result of wear and tear due to the ingress of dirt. All of this usually leads to the fact that the pawl remains in its raised position in relation to the rotary latch in the example considered and can no longer be reset by the motor. In such a case, the associated motor vehicle lock can accordingly no longer be closed, which also applies to the associated motor vehicle door.
  • a movable pin is provided in this connection as a manipulation element which can be acted upon manually and which, by rotating about its longitudinal axis in the malfunction mode, permits mechanical opening from the outside.
  • the invention is based on the technical problem of further developing such a drive unit for motor vehicle applications in such a way that an inexpensive and simply constructed and weight-reduced embodiment is provided.
  • a generic drive unit for motor vehicle applications is characterized in the context of the invention in that the manipulation element for reversing the drive must first be transferred from a basic position to the engagement position.
  • a specially designed manipulation element that can be manually loaded is used first.
  • This manipulation element is consistently in its basic position. In the basic position, the manipulation element cannot reverse the drive or fundamentally cannot interact with the drive.
  • the manipulation element for reversing the drive must first be transferred from the basic position to the engagement position. Only when the manipulation element is in the engaged position in comparison to the electromotive drive is it also possible to reverse the electromotive drive or generally to interact with the electromotive drive.
  • the motor vehicle door lock which is closed in this way by means of the manipulation element can of course be opened again in the event of a failure of the electric motor drive, for example via an outside or inside actuating lever chain. In the simplest case, this can be done and carried out via an outside door handle or, if appropriate, a locking cylinder or a mechanical manipulation element.
  • any of the drive units described above for automotive engineering applications can be reversed using the manipulation element in the event of a failure of the electromotive drive.
  • a window lifter drive can be acted on in this way with the aid of the manipulation element that can be acted on manually in such a way that a window that is not completely closed, for example, is closed manually with the manipulation element.
  • a seat adjustment that has failed, for example, can be adjusted manually with the aid of the manipulation element that can be acted upon to such an extent that an at least medium-term acceptable seating position can be set up in this way. This is where the main advantages can be seen.
  • the manipulation element is moved manually and preferably against spring force from the basic position into the engagement position.
  • the procedure is usually such that the manipulation element is moved substantially perpendicular to a drive plane spanned by the drive in order to change from the basic position to the engagement position.
  • This ensures that the manipulation element in the basic position is different from the one spanned by the drive Drive level is spaced.
  • the manipulation element does not have to be "dragged along" when the drive is actuated by an electric motor.
  • the electric motor drive can consequently be dimensioned in such a way that only the movements of the actuating element need to be implemented. This reduces the cost of the electric motor drive and also its weight.
  • the manipulation element is generally largely in two parts.
  • the manipulation element is usually composed of an actuating element and an engagement element.
  • the actuating element and the engaging element can be made in one or two pieces.
  • one-piece design of the actuating element and engaging element will be realized for cost reasons.
  • an expression as a one-piece plastic injection molded part for realizing both the actuating element and the engagement element has proven to be particularly favorable. This keeps costs down and weight.
  • the design is usually made so that the actuating element in the basic position is essentially flush with a cover on the head side.
  • the actuating element can be manipulated properly on the one hand and a protected attachment in or behind the cover is realized on the other hand.
  • the cover can be a connecting plate between the outer door plate and the inner door plate of a motor vehicle door. If one considers a drive unit as a window regulator drive, the cover may be designed as an interior lining of the motor vehicle door.
  • the actuating element is usually equipped with an actuating opening for engaging a manipulation tool.
  • the manipulation tool can be a screwdriver, a coin, a key, etc.
  • the manipulation element becomes the transition from the basic position into the engagement position by pressing against the Force applied by a spring.
  • the actual reversing with the aid of the manipulation element which can be acted upon manually corresponds to the fact that the manipulation element is set in rotation using the manipulation tool in question.
  • the reversing takes place in the engagement position against the force of the spring.
  • the manipulation element takes up its basic position again.
  • the spring thus ensures a return movement of the manipulation element from its engagement position to the basic position as soon as the force acting on it ceases to exist.
  • the engagement element is generally a pinion that can be brought into engagement with a worm wheel of the drive.
  • the electric motor drive mostly consists of an electric motor and an output worm arranged on its output shaft. The output worm meshes with the worm wheel. If the electromotive drive fails, the engagement element with the pinion formed there can now be brought into engagement with the worm wheel. As a result, the electric motor drive or the actuating element acted upon by it can be moved, at least reversed, with the aid of the manipulation element, independently of the electric motor.
  • the engagement element is generally supported against a base plate by means of the spring.
  • the drive unit is arranged between the base plate and the cover already mentioned and is consequently protected between the base plate and the cover.
  • the spring now ensures that the manipulation element is transferred manually from the basic position into the engagement position against the spring force.
  • the manipulation element automatically returns to the basic position.
  • a guide for the actuating element and consequently the manipulation element as a whole is additionally provided. This guide is generally found in or on the cover.
  • the design is usually made such that the engagement element rests against the guide on the foot side in the basic position of the manipulation element.
  • leadership takes on a dual role. On the one hand, it ensures the correct movement of the manipulation element from the basic position into the engagement position and back. This is regularly done linearly along the guide.
  • the guide with the engaging element in contact with the guide in the basic position on the foot side ensures that the spring acting on the engaging element only loads the manipulation element into the basic position to such an extent that the actuating element in the said basic position essentially aligns with the cover on the head side and also can escape. This means that the guide also acts as a stop for the manipulation element in the basic position.
  • a drive unit for motor vehicle applications is made available which, at least in the event of a function-related failure, at least enables reversing by manual means.
  • the manipulation element which can be acted upon using a manipulation tool must first be transferred from its basic position to the engagement position.
  • the manipulation element changes from the engaged position to the basic position without being acted upon, so that an opening in the cover, which is obligatory in this connection, is closed by the actuating element and contamination is avoided.
