Definitions

• the invention relates to a motor vehicle lock housing arrangement with at least one lock housing and a support housing, the lock housing being set up to accommodate at least one component on the locking mechanism side, such as an actuator, the support housing also accommodating at least one electronics support, and the lock housing and the carrier housing are connected to one another in a media-tight manner.
• the invention relates to a motor vehicle lock housing arrangement, ie a housing arrangement for a motor vehicle lock.
• the motor vehicle lock in question is generally arranged in or on an associated motor vehicle door, a motor vehicle hatch, etc., but can in principle also be placed on or in a motor vehicle seat, for example.
• the relevant motor vehicle lock typically interacts with a lock holder on the body.
• the motor vehicle lock is generally equipped with a locking mechanism consisting of a rotary latch and a pawl, which interacts with the lock holder in question in order to detachably connect the motor vehicle door, motor vehicle flap or even the motor vehicle seat to the body or to the body to secure.
• the motor vehicle lock housing arrangement there is equipped with a circuit board housing for accommodating a circuit board including electronics.
• the circuit board housing is also coupled to the rest of the lock housing in a liquid-tight manner. Because this is where a plastic injection molding connection is ultimately implemented.
• the flexibility is restricted, which affects the design of the electronics carrier, including the circuit board housing or carrier housing on the one hand and the lock housing with the component on the locking mechanism accommodated therein on the other hand.
• the component on the ratchet side is an actuator, with the aid of which the ratchet can be opened.
• Locking-side component means a component that interacts directly or indirectly with the locking mechanism.
• the locking mechanism is in turn mounted on a lock plate or a lock case.
• EP 2 754 799 B1 deals with an electric vehicle lock that has a first and essentially plate-shaped support body that carries the locking mechanism and consequently also a locking mechanism.
• another second supporting body is realized, which in turn arranges a printed circuit board in a position transverse to the plane spanned by the first supporting body.
• the second support body has a fluid-tight housing.
• the invention is therefore based on the technical problem of developing such a motor vehicle lock housing assembly so that a flexible design for the realization of different functions and / or attachments to changing installation locations is made available.
• a generic motor vehicle lock housing arrangement is characterized within the scope of the invention in that the carrier housing and the electronics carrier define a preassembled unit which is modularly coupled to the lock housing with the interposition of at least one seal.
• the lock housing and the carrier housing consequently enter into a media-tight connection with one another, as before and unchanged.
• the components accommodated and housed in the lock housing and carrier housing i. H. the component on the locking side, such as the actuator on the one hand and the electronics carrier on the other hand, is protected inside the composite housing made up of the lock housing and the carrier housing.
• the housing in question is designed in at least two parts, namely composed of the lock housing and the carrier housing. Most of the time, the housing in question consists of the lock housing and the carrier housing, although in principle other housing parts can also be added. As a rule, however, only the lock housing and the carrier housing are realized, which are connected to one another in a media-tight manner and in this way define and fix the assembled housing.
• the carrier housing and the electronics carrier now also describe a preassembled structural unit.
• This structural unit becomes modular with the interposition of at least one seal with the lock housing coupled. Due to the modular coupling, the carrier housing and the electronics carrier or the preassembled unit on the one hand and the lock housing on the other hand define modules or components that are connected to one another via a mechanical interface, which in turn is sealed media-tight using the seal.
• the modular character of both the carrier housing including the electronics carrier or the associated pre-assembled unit and the lock housing now opens up the possibility of being able to easily adapt both the carrier housing or the electronics carrier and the lock housing to the respective requirements in terms of function and/or installation location.
• the electronics mount usually has electronic components, which usually and obligatorily include a control unit.
• one or more sensors can be provided.
• the electronics carrier in question is additionally equipped with one or more energy sources or emergency energy sources. With the help of this energy source, for example, an emergency power supply to the actuator can be carried out in order to still be able to electrically unlock, electrically open, etc. the locking mechanism even if a vehicle battery fails.
• the energy source or emergency energy source in question may be designed as a battery, capacitor, etc. individually or in combination. If such an “emergency power supply” is not required in the example, the electronics carrier and the carrier housing that accommodates it can be designed differently and generally smaller and more compact. Nevertheless, due to the modular coupling with the lock housing, the mechanical interface of the structural unit to the lock housing realized at this point is designed unchanged. As a result, in the example, one and the same lock housing can be modularly coupled with different preassembled structural units from the carrier housing and the electronics carrier, namely in one in the example first version with an emergency power source and a second version without an emergency power source. Of course, other variants are also conceivable.
• both the different functions (with or without an emergency energy source) and changing installation or mounting locations can be taken into account.
• the design of the emergency energy source can of course also be changed in terms of its energy storage capacity. All of this is done while maintaining the mechanical interface between the preassembled structural unit consisting of the carrier housing and the electronics carrier on the one hand and the lock housing on the other. Due to the fact that the interface is closed using the at least one seal, the desired medium-tight connection between the lock housing and the carrier housing is still available and unchanged after they have been combined to form the housing.
• the lock housing is or can also be modularly coupled to the structural unit, the lock housing can also be easily adapted to the desired function or installation location.
• Such an adjustment can be made, for example, in such a way that the locking-side component, such as the actuator, is selected depending on the specific requirements and accommodated in the lock housing so that it can be replaced. So it is conceivable to design the actuator from an electric motor plus gear or without a gear.
• the actuator depending on the forces to be built up by the actuator, for example to open the locking mechanism, it is possible to work with differently designed (translated) gears.
• the modular coupling between the unit and the lock housing ensures that the lock housing while maintaining the mechanical interface to the unit can be correctly and modularly coupled to the unit in question, with the additionally provided seal ensuring the media-tight closure of the mechanical interface in question. That is, the mechanical interface of the lock housing to the pre-assembled unit is retained, regardless of whether the lock housing in the example described is an actuator with only one electric motor, an actuator with a high-ratio gear, an actuator with a low-ratio gear, etc. optionally absorbs in its interior.
• the medium-tight coupling between the pre-assembled unit and the lock housing taking into account the retained mechanical interface, always ensures the media-tight housing of both the actuator and the electronics carrier in the assembled housing. This is where the main advantages can be seen.
• the preassembled structural unit made up of the carrier housing and the electronics carrier also has a base carrier.
• the base carrier can be an electrical component carrier, ie a carrier for electrical components, for example for accommodating at least one sensor.
• the electronic component carrier in question typically has inserted or applied electrical conductor tracks. These can also be made available in the form of a stamped grid overmoulded with plastic.
• the electronic component carrier itself represents a ready-to-install unit which, in the example, has and carries at least one sensor and makes electrical contact with it.
• the layout is usually such that the base carrier is arranged between the electronics carrier and the lock housing.
• the base support is coupled to the electronics support via an electrical interface.
• this electric Interface is, for example, an electrical plug connection.
• the base support can be equipped with plug pins, for example, which engage in a socket of the electronics support for electrical contacting.
• the reverse procedure can also be used.
• the electronics carrier has the electrical connector pins in question, which engage in the socket on the base carrier. Either way, combining the base carrier with the electronics carrier ensures their mechanical and electrical connection at the same time.
• the base support and the electronics support are generally arranged together in the support housing and are accommodated by the support housing.
• the design is usually such that the carrier housing, the electronics carrier and the base carrier define the preassembled unit in this case, which is or is modularly coupled to the lock housing with the interposition of the at least one seal.
• the electrical interface is advantageously encapsulated within the structural unit.
• the design is usually made in such a way that the sensor carried by the base carrier or by the electronic component carrier and mounted on it works without contact.
• a mechanical connection between, on the one hand, the sensor in question and, on the other hand, for example the locking mechanism, a lever interacting with the locking mechanism, etc. is not required.
• the electronics mount and the base mount can also coincide. Then, for example, a continuous electronic component carrier will be used.
• the invention recommends that, advantageously and additionally, a lock plate supporting the locking mechanism be provided.
• the lock plate can in turn be modularly connected to the housing already explained above.
• the housing is usually made of the Carrier housing and the lock housing together, mostly final.
• the housing in question can now in turn be modularly coupled or connected to the lock plate according to the invention.
• the housing in question is sealed according to the invention with respect to the lock plate. This is usually done in such a way that the component on the ratchet side in the lock housing is routed to the outside via a seal.
• the ratchet-side component in the lock housing is usually the actuator, this means that the actuator is guided to the outside with the help of the seal in question, so that in this way the housing as a whole is sealed against the lock plate and can be sealed. Because the actuator can work on the ratchet, taking into account the interposed seal, with the help of which it is guided out of the housing to the outside. As a result, the housing as a whole can be designed to be media-tight and hermetically sealed.
• the modular connection between the housing and the lock plate expresses and means according to the invention that a standardized mechanical interface is implemented between the housing and the lock plate, which is retained, regardless of the specific design of the housing on the one hand or the lock plate or the her carried lock on the other hand.
• the lock plate is basically designed to accommodate locking mechanisms with, for example, differently designed rotary latches and/or pawls while retaining the mechanical interface to the housing.
• the housing can also be constructed in different ways, for example depending on whether the previously mentioned “emergency power supply” is desired and necessary as a function or not.
• the mechanical interface between the housing and the lock plate is not necessarily equipped with a seal. In fact, there is no need for such a seal in the area of this mechanical interface because the housing is sealed off from the lock plate. In other words, the housing as a whole is hermetically sealed against media such as water, dust, grease, etc. Nevertheless, the ratchet-side component inside the lock housing and thus the housing as a whole can work on the ratchet carried by the lock plate and mounted thereon. This is achieved in that the component on the ratchet side in question is guided outside of the housing via the seal and can be brought into engagement with the ratchet in the course of the mechanical coupling of the housing to the lock plate.
• a motor vehicle lock housing arrangement is made available within the scope of the invention which, due to its modular character, enables flexible adaptation to different desired functions within a motor vehicle as well as attachment to different positions or taking into account differently designed installation locations.
• the essential components of the motor vehicle lock housing arrangement according to the invention namely, for example, the actuator, a control unit and sensors, are accommodated in the housing in a media-tight and protected manner.
