Definitions
- the invention relates to an actuator for automotive applications, having an actuator, an electric motor, a transmission connected downstream of the electric motor, with the actuator being able to be moved out of and in from a housing of the actuator by means of the transmission, and a connection socket for electrical contacting of the actuator with a connection plug.
- Actuating drives are used in motor vehicles where actuating movements or locking mechanisms are to be provided, with a tank locking mechanism, a charging plug locking mechanism or the opening of a flap element being able to be named as examples.
- Electric drives with an actuating element are mostly used where comfort functions are to be increased or where the vehicle needs to be secured.
- the actuator can be used, for example, in a tank flap lock or in a charging plug lock in a hybrid or electric vehicle.
- the actuating element that can be moved out or in from the housing of the actuator is used, for example, to serve directly as a bolt or to actuate a bolt element in such a way that, for example, opening of a tank flap can be prevented.
- the actuator can serve to lock the flap and/or to open the flap.
- this area must be protected against the ingress of environmental influences such as rain, snow or dust, so that a tight seal of the housing of the actuator, but also of the control element itself, can be guaranteed. the must.
- the sealing with regard to the environmental influences means that the functional components in engagement with the actuating element, such as the motor and gearing, must be accommodated in the actuating drive in a sealed manner.
- a generic actuator is known from DE 102 59 465 A1.
- the document discloses an actuator for motor vehicle applications with an actuator, an electric motor, a transmission connected downstream of the electric motor, the actuator being able to be moved out of and in from the housing of the actuator by means of the transmission.
- the actuating element itself is accommodated in a bellows, with the bellows closing off or accommodating the actuating element in a sealing manner in relation to the housing.
- an air-permeable but moisture-impermeable membrane is arranged in the housing.
- the membrane consists of a semi-permeable plastic material made of a semi-permeable and direct PTFE. This semi-permeable layer is supported and held by a supporting layer made of a carrier material, also made of plastic.
- Polyamide (PA) is usually used here, whereby both layers can be connected to each other with an adhesive.
- the object of the invention is to provide an improved actuator.
- an actuator for motor vehicle applications having an actuating element, an electric motor, a transmission connected downstream of the electric motor, the actuating element being able to be moved out of and in from a housing of the actuating element by means of the transmission , and a connection socket for electrical contacting of the actuator with a connection plug, with a pressure equalization in the actuator being able to be implemented by means of the connection socket.
- the actuator requires electrical contact so that on the one hand the functional components of the actuator can be controlled and on the other hand control means arranged in the actuator, such as microswitches, can be connected.
- an area of the actuator is thus available for ventilation and venting, which is connected by the plug-socket Connection sealed on the one hand and on the other hand forms a contact point between the actuator and motor vehicle.
- This contact area is particularly sealed by the plug-socket connection, so that pressure equalization or ventilation can be carried out through the connection socket without further sealing measures on the actuator.
- the entire housing of the actuator can be tightly closed all around, which in turn represents an advantage when used in the area of strong environmental influences.
- the aeration and venting or the pressure equalization runs in an area of the connection socket, which shifts the aeration and venting to an area outside the functionalities of the actuator.
- the housing of the actuating drive encloses the functional elements, electric motor, gear, switching means, actuating element and/or electrical control parts, with the housing having a recess only in the area of the actuating element, through which the actuating element can be moved out of the housing and into the housing.
- the actuating element itself can be sealed by a bellows, for example.
- the housing itself can be closed by a peripheral seal and/or, for example, by means of a laser welding process. With this type of sealing of the functional components and the interior of the actuator, use can also be guaranteed under extreme weather conditions. Since the pressure equalization has now also been shifted to an area that is separately sealed by the plug-socket connection, improved tightness can be achieved with the same functionality.
- a vent cooperating with the opening is provided in the connector plug.
- Connection socket opening and connection plug cooperate in such a way that on the one hand an opening is provided in the housing and on the other hand ventilation can be guaranteed through the plug.
- the connection plug for the actuator is designed in such a way that the opening is overlapped at least in some areas by the ventilation of the connection plug. device, so that a pressure equalization is made possible starting from the actuator of the connection plug. If, for example, the actuating element is moved into the actuating drive from an extended position into a retracted position, the tightness of the actuating drive and the bellows in the region of the actuating element can lead to increased pressure in the actuating drive.
- This pressure can be equalized through the opening in the housing and in the area of the connection socket, since pressure equalization can be made possible through the opening in the direction of the connection plug. Even if a bellows for sealing the actuating element is primarily described here, it is of course also conceivable that a seal integrated into the housing, through which the actuating element is moved, can be used to seal the actuating element.
- the openings and a ventilation opening directly adjoin one another.
- the opening in the connection socket forms an opening in the direction of the functional components of the actuator and is connected to the interior of the actuator in such a way that, for example, any moisture that occurs can escape from the opening or air can circulate in the sealing groove inside the actuator.
- the openings within the connection socket are in direct contact with a ventilation opening in the connection plug, that is to say the openings in the connection socket and the ventilation openings in the connection plug advantageously form the same or almost the same dimensions. As a result of the direct adjoining or also the matching dimensions, the most efficient possible ventilation of the interior of the actuator can be ensured.
- the ventilation opening is part of a ventilation channel in the connector plug.
- the vent opening forms a matching recess in the connector plug with the opening in the housing.
- the ventilation channel is connected to the ventilation opening, whereby the ventilation can advantageously be guided into an area that is suitable for favorable ventilation in relation to the arrangement of the plug on the actuator or in the motor vehicle.
- the ventilation can also take place in areas that are arranged at a distance from the actuator.
- the connector plug has an outlet opening, in particular an outlet opening for the ventilation duct, a further embodiment variant of the invention results.
- the connector plug can have an opening, for example, in the area of a line connection or of a cable exiting the plug, if this opening is arranged, for example, in a dry area of the motor vehicle.
- the ventilation duct extends along the plug and at least in some areas also along the connection cable or the control line for the actuator.
- the ventilation opening or the ventilation channel then has an outlet opening which is not subject to any further environmental influences in the dry area of the motor vehicle.
- the outlet opening can also be arranged directly on the plug-in element of the connector plug if the connector plug is located so far away from the area affected by rain, dust, etc.
- the outlet opening can advantageously be made impermeable to moisture.
- an outlet opening can be provided on the connector plug itself, which is then used to equalize the pressure and to protect against the ingress of moisture.
- the housing of the actuator can be completely sealed and, for example, pressure can be equalized through the plug connection on the actuator.
- the outlet opening can be supported and held with a semi-permeable plastic material with a supporting layer made of a carrier material, also made of plastic.
- a polyamide is usually used here, with both layers being able to be connected to one another by means of an adhesive.
- the outlet opening which is closed by means of the semi-permeable plastic, ensures that an exchange of air between the interior of the actuator, or the bellows and the housing, and the external ambient air is guaranteed, with moisture not being able to penetrate. However, the formation of condensate inside the actuator is avoided. prevents and ensures pressure equalization during movements of the actuating element between the inner volume and the outer ambient air.
- the outlet opening is arranged at an end of the connector plug opposite the ventilation opening.
- a ventilation opening that runs essentially in a straight line can ensure reliable ventilation of the interior.
- this embodiment enables a cost-effective and structurally simple possibility of providing ventilation of the actuator.
- a connector seal is advantageously arranged in the area between the opening and the ventilation opening between the connector plug and the connector socket.
- the connector seal completely encloses the openings in the connector plug and in the connector socket, so that additional security can be provided for sealing the housing of the actuator.
- FIG. 1 shows a plan view of an actuator with a connection socket and a connection plug inserted into the connection socket
- FIG. 2 shows a basic representation of a connector plug designed according to the invention along the line II-II from FIG.
- FIG. 1 shows a top view of an actuator 1 and, in particular, of a housing 2 of the actuator 1 .
- the housing 2 has through holes 3, 4, by means of which the actuator 1 can be arranged, for example, on a motor vehicle in the area of a charging socket.
- An actuating element 5 can be moved in the direction of arrow P out of the housing 2 of the actuator 1 and back in again.
- the actuating element 5 can be sealed during movement by means of a bellows 6 indicated as a dot-dash line.
- the actuator 1 has a connector socket 7 into which a connector plug 8 is shown inserted as a separate component.
- the connector plug 8 in turn has a connector socket 9, it being possible for the connector socket 9 to serve as a motor vehicle-specific connector interface, for example.
- the actuator housing 2 can, for example, be connected to a clip connection 10, 11 for assembly and/or have a circumferential laser welded connection.
- FIG. 2 now shows a basic illustration of a connector plug 8 designed according to the invention.
- FIG. 2 shows a section through a ventilation channel 12 inside the connector plug 8.
- An opening is arranged in the housing 2 of the actuator 1, which corresponds to a ventilation opening 14 in the position.
- a plug seal 15 is arranged between the connector plug 8 and the connector socket 7 and serves to seal between the connector components 7 , 8 .
- Further peripheral seals 16 can be arranged, for example, on an upper edge of the connection socket 7 and/or on the connection plug 8 .
- the venting channel 12 extends essentially in a straight line along a center line M through the connector plug 8 and is widened at the end, with the venting channel 12 ending in an air-permeable but moisture-impermeable membrane 18 .
- the membrane 18 is able to let air through the membrane 18, for example in the direction of the arrows P1, in the event of an overpressure in the actuator 1, whereas the membrane 18 is impermeable to moisture. sig is formed.
- a pressure equalization or a ventilation of the actuator 1 is of course also possible through the membrane 18 .
- the connector plug 8 is used to control the actuator and to make electrical contact with the components inside the actuator 1.
- control and supply lines 19, 20 are indicated in principle in FIG.
- the control and supply lines 19, 20 can be connected on one side to an electric motor 21, for example, whereas the control and supply lines 19, 20 can be connected to a motor vehicle-specific plug by means of the connection socket 9.
- a pressure equalization or a ventilation of the actuator 1 can be shifted to an area outside of the housing 2 . In this way, ventilation processes can be shifted to areas that are less or not at all subject to environmental influences.
