Definitions

  • Such a motor vehicle door lock is previously known from DE-PS 35 26 501.
  • the motor vehicle door lock has a housing that u. a. has a cover.
  • An electric servomotor of a central locking system is provided as the actuator of a security device. This servomotor is arranged inside the housing, covered by the cover, and is inaccessible from the outside.
  • the arrangement of the actuator in the interior of the housing is space-consuming, since a space must be provided for the actuator in the interior of the housing, which can be difficult in the arrangement of the large number of mechanical components.
  • a pneumatic actuator with a correspondingly large one Space requirements can lead to an increase in the size of the entire motor vehicle door lock and to installation problems in motor vehicle doors.
  • the actuator is arranged on the cover and that the actuator housing is at least partially integrally formed with the cover.
  • the actuator is arranged on the cover, it can, for. B. designed for repair and maintenance work accessible from the outside.
  • These measures according to the invention further simplify production and reduce the cost involved, since the assembly of the large number of mechanical parts can take place first in the remaining housing part of the motor vehicle door lock. Then the cover, which is required anyway, can be placed together with the actuator on the remaining housing of the motor vehicle door lock and connected to this housing part. Due to the construction of the motor vehicle door lock according to the invention, it is not necessary to lay supply lines for supplying the actuator inside the motor vehicle door lock housing.
  • the space required for the actuator can be significantly reduced compared to the prior art, since a migration of the cover acts as an actuator in the housing part at the same time.
  • This is particularly advantageous when using pneumatic actuators of pneumatic central locking systems, since these actuators require a comparatively large amount of space and, like the cover hoods, are often injection molded from plastic.
  • this measure according to the invention also reduces the cost of manufacturing the motor vehicle door lock according to the invention, since, for. B. less plastic mass is required to spray the housing parts of the actuator and the cover.
  • the dimensional accuracy of the parts is also favorably influenced, so that when the cover is placed on the rest of the housing part of the motor vehicle door lock, a secure engagement z.
  • the actuating rod of a pneumatic actuator is guaranteed in the other lock parts.
  • the motor vehicle door lock according to the invention is simpler and cheaper to manufacture than the known, requires less space and is easier to maintain and repair due to the accessibility of the actuator from the outside even when the motor vehicle door lock housings are closed.
  • the actuator housing part facing the other door lock housing is formed in one piece with the cover hood.
  • the actuator housing part which is formed in one piece with the cover hood can have a guide for an actuating rod of the actuator which is also in particular formed in one piece with the cover hood.
  • the actuator of the motor vehicle door lock can advantageously be a pneumatic actuator.
  • pneumatic actuators are often used in motor vehicles as part of pneumatic central locking systems. So far, an arrangement of pneumatic actuators on the housings of motor vehicle door locks has not taken place essentially because, because of the comparatively large space requirement of the pneumatic actuators, this combination would have increased the space requirements of the door locks.
  • the actuator housing part which is formed in one piece with the cover hood, can advantageously have a particularly circumferential groove for receiving a bead of a membrane of the pneumatic actuator. This is particularly useful because it is possible with this measure, e.g. B.
  • the cover can advantageously have a pressure connection piece for connecting the actuator to the pneumatic control unit.
  • the cover can also advantageously have an electrical switch for detecting the actuator position.
  • Such switches are often provided in the actuators to provide feedback of the end positions of the actuator and thus the closed state of the motor vehicle door lock z. B. to enable the central locking system.
  • the arrangement of the switch in the cover is advantageous because in this arrangement, as for the actuator for the switch, no electrical leads have to be installed in the motor vehicle door lock housing. The switch can then almost directly detect the actuator position, for example on the membrane of a pneumatic actuator.
  • a part of an electrical plug connection in particular a plug, can be arranged in the cover, which is advantageously formed together with the switch and thus makes the use of electrical lines from the switch to the plug unnecessary.
  • the actuator is an electromagnetic actuator which is to be connected to a power source by means of electrical connections.
  • electromagnetic actuators can be servomotors or solenoids of electromotive or electromagnetic central locking systems.
  • actuators can also, for. B. solenoids of anti-theft systems, as they are known from DE-PS 36 27 036.
  • Such actuators of anti-theft systems can certainly be designed together with actuators from the central locking systems according to the present invention.
  • the actuator housing part which is formed in one piece with the cover, has a particularly sealed passage for an actuating rod of the actuator. With these measures, the penetration of moisture and dust from the motor vehicle door lock side into the electromagnetic actuator can be prevented.
  • the actuator has first electrical connection lugs which are directed towards the cover and if the cover or the plug has second electrical connection lugs which engage in slots in the first connection lugs.
  • the cover hood can be injection molded from plastic in a particularly advantageous manner, because this is a particularly simple and inexpensive solution and also enables the design of complicated shapes of the cover hood and housing parts.
  • the first actuator housing part (3) of the first actuator (2) has a guide (5) for a first actuating rod (6) of the pneumatic first actuator (2), which is also molded in one piece with the first actuator housing part (3) from plastic.
  • a circumferential groove (7) is also provided in the first actuator housing part (3) or in the corresponding part of the cover (1), for receiving a membrane bead (8) of the membrane (9) of the first pneumatic, which is made of an elastic material, in particular rubber Actuator (2).
  • a second actuator housing part of the first pneumatic actuator (2) is formed by a cover (10) which is detachably connected to the first actuator housing part (3) or the cover (1) by latching means (11) for assembly and repair purposes, if necessary.
  • the cover (10) has a pressure connection piece (12).
  • An electrical switch (13) is also provided, which the actuator position, that is, the position of the actuating rod (6) and thus the membrane (9) optionally scans via a bell crank.
  • This electrical switch (13) is designed in one piece with a plug (14) and can be inserted together with the plug (14) into a corresponding opening in the cover (10).
  • the motor vehicle door lock according to the invention additionally has a second actuator (15) of an electromagnetic anti-theft system.
  • the first actuator housing part (3) of the second actuator (15) has a sealed bushing (16) for a second actuating rod (17) of the second actuator (15).
  • the second actuator (15) For the electrical connection of the second actuator (15) to a power source, the second actuator (15) has first electrical connection lugs (18) which surround second electrical connection lugs (19), which in turn are arranged on the plug (10). On the right in FIG. 1, an electrical connection (20) is provided for further electrical switches, which are also arranged in the cover (1).
  • FIG. 2 the same or equivalent device parts as in FIG. 1 are provided with the same reference numerals. It can be seen that the first connecting lugs (18) have slots (21) for receiving the second connecting lugs (19).
  • the motor vehicle door lock according to FIGS. 1 to 3 is assembled as follows:
  • the cover with plug (14), switch (13) and second electrical connection lugs (19) can then be pressed onto the cover (1) in such a way that the second connection lugs (19) into the slots (21) of the first electrical connection lugs (18 ) are pressed in, the bead (8) is pressed into the groove (7) and the cover (10) is locked with the cover (1) by means of the locking means (11). Finally, the cover (1) is locked with the rest of the door lock housing (4) and the motor vehicle door lock according to the invention is fully assembled.
