Definitions

  • the invention relates to a plastic housing for motor vehicle applications, in particular a plastic lock housing of a motor vehicle lock, preferably a plastic door lock housing of a motor vehicle door lock, with at least one rotary bushing provided in a wall with a seal for a pivot.
  • Plastic housings for motor vehicle applications are used in a variety of ways, for example to enclose a drive unit for a motor vehicle assembly, as can be seen from DE 20 2008 010 051 U1.
  • the drive unit is arranged inside the plastic housing and has at least one rubber-elastic bearing for fixing the motor to a base.
  • the rubber-elastic bearing is designed at least partially like an accordion in axial section and/or radial section. This allows different spring constants to be implemented. This is intended to provide a perfect mounting for the engine that is simple in terms of assembly.
  • the generic DE 10 2004 026 065 A1 is about a motor-actuated lock for doors or flaps of vehicles.
  • elastic members are arranged at a connection point between a motor housing and a lock housing, which can form a preassembled structural unit with the motor housing. This assembly can be attached as a whole to the connection point of the lock housing.
  • Plastic housing for motor vehicle technical applications and in particular plastic lock housing of a motor vehicle lock are equipped with the fundamental advantage that on the one hand they have a have a low weight and on the other hand can be produced inexpensively and in a plastic injection molding process with practically any shape.
  • a further advantage of such plastic housings is that they are generally easy to seal. This is particularly important against the background that such plastic housings are often exposed to splashing water, dust or generally unfavorable environmental conditions, which reduce the service life of a drive unit typically housed inside or generally movable aggregates.
  • DE 20 2008 010 051 U1 uses a rubber-elastic bearing through which a Bowden cable is routed to the outside and ensures a tight passage.
  • sealing problems can arise in connection with a pivot pin guided to the outside through the known seal. The same applies when looking at DE 10 2004026 065 A1.
  • an output shaft of an electric motor is guided to the outside by a ring body made of elastic material.
  • the ring body serves not only to seal a passage, but also to guide the output shaft of the motor. This can lead to leaking problems again.
  • the invention is based on the technical problem of further developing such a plastic housing for motor vehicle applications in such a way that the tightness of the rotary feedthrough with seal for the pivot pin is improved overall compared to the prior art.
  • the invention proposes in a generic plastic housing for motor vehicle applications that the seal is designed as a hat seal that is connected to both the pivot and the wall and can be rotated or twisted during operation of the pivot.
  • a special seal is used within the scope of the invention, namely a hat seal.
  • Such a hat seal typically has a pivot rim on one side and a wall rim on the other, with a skirt positioned therebetween.
  • the jacket is rotated or twisted during operation of the pivot.
  • the seal or hat seal is firmly connected to the pivot with its pivot flange. The same applies to the wall brim, which is also firmly connected to the wall.
  • the invention is based on the finding that a specially designed hat seal provided at this point can easily absorb the rotary movements performed by the pivot pin in such motor vehicle applications in the sense of twisting.
  • angular movements of the pivot pin of usually 180° at the maximum and usually even 90° at the maximum are sufficient to carry out desired adjustment movements via the pivot pin inside the plastic housing or being able to initiate and complete outside of this.
  • the hat seal is adhesively bonded to the pivot.
  • the adhesive connection can be implemented and realized in detail in such a way that the seal is glued and/or molded or vulcanized onto the pivot pin.
  • the latter variant can be implemented cheaply and easily, particularly in the event that the pivot pin is made of plastic, as is the hat seal.
  • the hat seal can, for example, be molded onto the plastic pivot in a two-component injection molding process or generally vulcanized on.
  • the hat seal is connected to a lever connected to the pivot, in particular a driver lever.
  • the hat seal can be connected to the pivot, to the attached lever, or to both.
  • the connection of the hat seal to the connected lever is usually with the advantage connected in that the lever in question is typically coupled to the pivot pin via a connecting flange which has a larger diameter than the pivot pin.
  • the cap seal is coupled to the connecting flange of the lever in the example over a greater length than when the cap seal is connected to the pivot, so that in this case there is a particularly permanent connection between the cap seal and the pivot or the lever and this can be observed.
  • the invention generally proposes a detachable press fit for coupling the hat seal to the wall. That is, the wall rim of the hat seal that is coupled to the wall at this point is not adhesively coupled to the wall in question. Rather, in this context, the invention falls back on the detachable press fit. This simplifies the assembly overall, because the pivot pin with the adhesively connected hat seal generally forms a preassembled structural unit, which in turn is then coupled to the rotary feedthrough and consequently to the wall. To do this, the wall brim of the hat seal is placed against the wall and fixed against the wall with the help of the detachable press fit. This can be implemented in the sense of a plug connection, a screw connection or whatever in detail.
  • the wall with the rotary feedthrough with seal for the pivot pin is usually a partition wall between a wet room housing part and a dry room housing part of the plastic housing.
  • the wet room housing part generally accommodates a locking mechanism consisting of a rotary latch and a pawl of an associated motor vehicle lock. Since such a locking mechanism usually interacts with a locking bolt on the motor vehicle and for this reason the locking bolt has to move into an inlet mouth of the plastic housing or wet room housing part, the wet room housing part is exposed to different environmental conditions.
  • the wet room housing part of the plastic housing in contrast to the dry room housing part, is not splash-proof and also not designed to be dustproof.
  • the wall having the rotary leadthrough according to the invention with the hat seal for the pivot bolt is designed as a partition wall between the wet room housing part and the dry room housing part, the wet room housing part is hermetically separated from the dry room housing part and the dry room housing part is sealed accordingly.
  • the fact that the two aforementioned housing parts are generally connected to one another in a sealing manner at the edge also contributes to this.
  • the edge connection of the two housing parts can be in the form of a welded connection and in particular a laser welded connection.
  • the rotary feedthrough with the hat seal for the pivot is generally the only connection between the wet room housing part and the dry room housing part, it is achieved within the scope of the invention overall that the dry room housing part with its aggregates located therein has a level that was previously not possible in the prior art maintained tightness. As a result, the aggregates located in particular in the dry room housing part are effectively protected against splash water or general moisture as well as against dust, so that the aggregates, which are often made of plastic, have a longer service life and favorable friction conditions compared to the prior art. This is where the main advantages can be seen.

  • the plastic door lock housing 4, 5 of the motor vehicle door lock is designed according to the exemplary embodiment and not restrictively in two parts and has a wet room housing part 4 and a dry room housing part 5. Since the locking mechanism 1, 2 with the lock case 3 is attached to the wet room housing part 4 or for this purpose belongs, the wet room housing part 4 is not protected from dust or splashing water in particular. Because the lock case 3 has, as usual, an infeed mouth, not expressly shown, via which a locking bolt can move into the locking mechanism 1, 2 and interact with it in a known manner. In contrast, the dry room housing part 5 is sealed against spray water and dust.
