Definitions

• the invention relates to a motor vehicle door lock, with a locking mechanism and a basic housing, the locking mechanism possibly being received in connection with other lock components in the basic housing and forming a basic module together with the latter. This means that the locking mechanism, possibly the further lock components and the basic housing together form the basic module.
• the other lock components may be actuating levers, locking levers, etc.
• at least one actuation lever and one release lever are implemented, which enable the locking mechanism to be opened.
• Motor vehicle door locks of this type have proven themselves, but they reach their limits when the same design concept is to be used, with the possibility at the same time of opening the lock by motor. This is where the invention comes in.
• the invention is based on the technical problem of further developing a motor vehicle door lock of the configuration described at the outset in such a way that it can be easily upgraded for motorized opening of the locking mechanism while maintaining the basic concept.
• a generic motor vehicle door lock within the scope of the invention is characterized in that the basic module with the basic housing and the locking mechanism accommodated therein, as well as the further lock components, is designed to accommodate an additional module with a drive for opening the locking mechanism.
• the add-on module has the desired drive, which ensures the motorized opening of the locking mechanism.
• Supplementary module and basic module can be easily combined.
• the add-on module may have at least one electric motor and a downstream transmission in an add-on housing.
• the invention is based on the knowledge that such an electric motor is usually designed to run fast and requires a downstream reduction gear.
• it has proven useful to design the gear unit as a spur gear unit in order to reduce the installation space required to a minimum.
• the gear housing shell primarily functions as a mount for individual gear elements or the spur gears mostly implemented at this point.
• the motor / connection housing usually bears the electric motor alone as well as a connecting plug, a connecting socket or comparable electrical connection devices, with the aid of which the electric motor is supplied with current.
• Both housing shells can advantageously be detachably connected to one another, both to facilitate assembly and to enable retrofitting and, if necessary, replacement in the event of a repair.
• the detachable connection can be realized in detail by a snap or clip connection or other connection measures.
• the Erganzungsgehau.se generally has at least one connecting web for coupling on the head side to the basic housing.
• two connecting webs are realized, which are of approximately the same length and are formed on the opposite side of the supplementary housing.
• the head of the basic housing is therefore connected to the base of the supplementary housing.
• the basic housing has an opening on the head side, while the supplementary housing has a slot on the foot side.
• An actuating arm of the release lever may be placed in the area of the opening on the head side of the basic housing.
• the transmission element on the output side carries a trigger cam which interacts with the actuating arm of the trigger lever. So if the base housing is combined at its head with the base of the supplementary housing, the head-side opening of the base housing and the base-side slot of the supplementary housing being matched to one another, the areas of action of the trigger cam on the output-side gear member of the drive and the trigger lever on the other hand automatically overlap , The interaction described above is therefore set automatically.
• the drive is able to work on the actuating arm of the release lever via the gear link on the output side and the release cam provided there.
• the supplementary module may also contain a blocking agent for the drive.
• the drive can be locked in its blocking position in order to avoid unintentional opening of the locking mechanism.
• the drive is only able to open the locking mechanism when the blocking agent is in its release position.
• the change from the regularly adopted blockage position to the release position usually takes place through a manual movement of an operator who is willing to access, which is mechanically transferred to the blocking means for its transfer from the blockage position to the release position.
• the blocking means is largely acted upon by a transmission element led out of the basic module.
• a motor vehicle door lock is provided, which impresses with its special modular structure.
• the basic module has all the essential lock components that are required to mechanically open the locking mechanism. This includes, for example, the release lever but also at least one actuation lever. Likewise, at least one locking lever - also in the embodiment as a central locking lever - may be implemented. If this basic module is now to be combined with a device for motorized opening of the locking mechanism, this can be achieved according to the invention by simply flanging an additional module onto the basic module, as it were. The add-on module is equipped with the drive then required to open the locking mechanism, the basic module even allowing the add-on module to be included.
