Definitions

  • the innovation relates to a pneumatic control element, in particular for central locking systems in motor vehicles with a housing, with a piston rod which is displaceably mounted in the housing, with a piston which is connected to the piston rod and which, together with a housing part, forms a pressure chamber with a pneumatic connection which connects the pressure chamber with a pressure source and with an electrical switch that can be actuated depending on the position of the piston rod relative to the housing.
  • Such pneumatic actuators are used as actuators for central locking systems in motor vehicles such. B. from DE-PS 31 50 564 and DE-OS 29 36 821 previously known.
  • the electrical switch is arranged outside the pressure chamber above the piston and is actuated directly or indirectly by the piston rod.
  • the known pneumatic control elements have the disadvantage that due to the known sensitivity of electrical switches to dirt and moisture, the housing space above the piston is sealed with additional sealants against the ingress of moisture and dirt. Much-like sealants are often only necessary for this reason, so that by the previously known arrangement of the switch additional costly to procure and assemble parts are required.
  • the present innovation has the task of developing the previously known pneumatic actuating elements in such a way that they can be manufactured more easily and more cost-effectively and that the required space is reduced compared to the previously known.
  • this object is achieved in that the switch is arranged in the pressure chamber and in that the switch can be actuated by the piston.
  • the pressure chamber of the pneumatic control element is connected via the pressure connection to a pressure source generating pneumatic overpressure and / or underpressure and, if appropriate, to pneumatic switching devices.
  • the connection is usually made via hose lines.
  • the pressure chamber is so compared to the environment of the pneumatic control element and environmental influences in this environment such. B. essentially sealed moisture and dirt. Due to the arrangement of the electrical switch in this pressure chamber of the pneumatic control element according to the innovation, the electrical switch is essentially completely protected against all environmental influences, such as in particular moisture and dirt, because the pressure chamber together with the other parts, for. B. the central locking forms a closed system against the environment.
  • the switch is actuated in a simple manner by the piston.
  • the pneumatic control element according to the invention has the advantage over the previously known pneumatic control elements that no additional installation space is required for installing the switch above the piston in the housing, so that the space requirement of the pneumatic control element according to the innovation, in particular its overall height, is reduced compared to the prior art.
  • the pneumatic control element according to the innovation is simpler and cheaper to produce than the prior art, because the arrangement of the switch in the pressure chamber means that no additional means or measures are required to protect the switch against environmental influences such as moisture and dirt.
  • stamp which can be displaced by the piston relative to the housing and by which the switch can be actuated in order to have more latitude with regard to the installation location of the switch in the pressure chamber and with regard to its installation position in the construction of the pneumatic control element according to the invention.
  • a spring which loads the plunger in the open position or a first switching position of the switch.
  • the stamp can have an extension that actuates the switch in order to also have greater scope in the construction of the pneumatic actuating element according to the invention. Especially when using the snap switch and when arranging the snap switch this particular embodiment is advantageous parallel to the stamp.
  • the switch is arranged on a plug-like part, the plug being insertable into a corresponding recess in the housing part.
  • the plug can have a guide in which the spring is arranged and in which the plunger is displaceably guided. This then has the advantage that the complete arrangement consisting of switch, plug, stamp, spring and, if necessary, approach are combined to form an assembly part and can be assembled together as a plug-like assembly part by inserting it into a corresponding recess in the housing part on the housing of the pneumatic actuating element according to the invention .
  • the switch is arranged on the same side of the housing as the pressure connection, because the pressure connection in each case takes up a structural depth and because the arrangement of the switch on the pneumatic control element according to the innovation hardly takes up any more space than the pressure connection.
  • the switch can be a snap switch which has a preferred switching position.
  • Such snap switches have the advantage of having a defined switchover point, so that the switchover takes place even with slight changes in the position of the piston or the piston rod relative to the housing.
  • the use of such snap switches caused difficulties because such snap switches have extensive mechanics, are of filigree structure and that is why they are particularly sensitive to environmental influences such as moisture and dirt.
  • a membrane in particular a rolling membrane, is provided which seals the piston against the housing part.
  • a correspondingly tight fit of the piston in the housing part can be dispensed with.
  • the only figure shows a pneumatic actuator according to the innovation in section.
  • the pneumatic actuator according to the invention has a housing (1) which consists of a first upper housing part (2) and a second lower housing part (3).
  • the two housing parts (2) and (3) are connected to one another by a known latching connection.
  • a piston rod (4) is arranged displaceably in the first upper housing part (2) of the housing (1).
  • the piston rod (4) is only weakly guided in the first upper housing part (2) in order to connect tolerances when installing the pneumatic control element according to the invention in the door or flap of a motor vehicle and a possible offset between the piston rod and the piston rod Compensate for parts of the other central locking system or the lock.
  • This weak guidance is accomplished in that a considerable play is provided between the piston rod (4) and the first housing part (2).
  • Due to the slits in the figure between the piston rod (4) and the first upper housing part (1) moisture and Dirt enter the space between the first upper case and a piston. This is harmless in the pneumatic control element according to the innovation, since no parts sensitive to moisture or dirt, in particular the electrical switch of the previously known pneumatic control elements, are arranged in this space.
  • the piston rod (4) is firmly connected to a piston (5).
  • the piston (5) is essentially enclosed by a rolling membrane (6), the edge of which is bead-shaped and is pressed all the way around in a corresponding groove between the first upper housing part (2) and the second lower housing part (3).
  • the lower second housing part (3) has a pneumatic pressure connection (8).
  • a recess or bore is provided in the second lower housing part (3), in which a plug-like part (13) is inserted in a pressure-tight manner via a seal and is locked in a known manner.
  • An electrical switch (9), which is designed as a snap switch, is arranged on or in the plug (13).
  • a stamp (10) is arranged parallel to the snap switch in the plug-like part or plug (13) in a corresponding guide (14).
  • the stopper (10) is loaded by a cylindrical spring (11) in the starting position shown in the figure.
  • the spring (11) is also arranged in the guide (14) of the stopper (13).
  • the stamp (10) has an extension (12) through which the switch (9) can be actuated.
  • the pressure connection (8) is connected in a known manner via corresponding hose lines to a pressure source, so that the arrangement consisting of the pressure chamber (7), the hose line and the pressure source, which in the Figure is not shown, forms a system closed to the environment of the pneumatic actuator.
  • the innovative pneumatic actuator has the advantage that no moisture or Dirt from the environment can get to the electrical switch (9), so that a malfunction of the electrical switch due to contamination or corrosion is almost impossible.
  • the new pneumatic actuator works as follows:
  • the figure shows the unlocking position of the pneumatic control element, which is characterized in that the piston (5) and thus the piston rod (4) are in the position facing away from the electrical switch (9).
  • the plunger (10) is relieved from the piston (5) so that the spring (11) pushes the plunger (10) out of the guide (14) of the plug (13) according to the figure.
  • the electrical switch (9) is also relieved of the attachment (12) and the electrical switch (9) has the switch position shown in the figure, in which the middle switch contact rests on the right fixed contact.
  • the pneumatic control element according to the innovation is now supplied with negative pressure from the pressure source (not shown in the figure) via the pressure connection (8), a negative pressure is formed in the pressure chamber (7), which presses the stamp (5) with the rolling membrane (6) in the direction of the electrical switch (9) actuated into the locking position.
  • the piston (5) presses the plunger (10) against the force of the spring (11) into the guide (14) of the plug-like part (13) via the rolling membrane (6).
  • the stamp (10) is thus moved down in the figure.
  • the electrical switch (9) has then changed its electrical switching state.
  • the stamp (5) together with the roller membrane (6) is pressed upwards again in the direction of the unlocking position shown in the figure.
  • the plunger (10) is relieved of the pressure by the piston (5) or the rolling membrane (6) and, due to the force of the spring (11), moves back upwards into the position shown in the figure.
  • the plunger (10) also moves the extension (12) upwards, so that the actuation of the electrical switch (9) by the extension (12), as shown in the figure, is canceled. Because of this relief, the electrical switch changes its switching state back to the position shown in the figure, in which the movable center contact rests against the fixed contact on the right in the figure.
  • the new pneumatic actuator can not only be used for central locking systems in motor vehicles.
  • the pneumatic control element it is also possible to use other devices in the motor vehicle such as. B. to control cooling air intakes in engine compartments with internal combustion engines.
