Definitions
- the invention relates to a motor vehicle door lock, which is provided for connection to a vehicle door, the motor vehicle door lock having a carrier plate, on or on which locking parts are mounted, and a lock housing that at least partially encloses the locking parts with the carrier plate.
- Motor vehicle door locks which are usually used, are supplied as a separate part to be assembled, which is then used by the vehicle manufacturer.
- the motor vehicle door lock mostly contains moving parts which have to ensure that the vehicle door is locked securely.
- door lock-side rotary latches are used, which work together with body-side bolts or blocks to lock the motor vehicle door.
- the locking parts have to absorb large forces because a break-in should be prevented as well as an undesired opening of the door in an accident. Therefore, the rotary latches and the pawls blocking the rotary latch and the parts storing them must be stably stored in the motor vehicle door lock.
- Another disadvantage is that it is costly to manufacture conventional door locks because of the high number of individual parts that have to be installed separately.
- the individual parts and the assembled unit are subject to high mechanical requirements with regard to reliability, particularly in the event of a crash.
- the invention has for its object to reduce the disadvantages mentioned above and to provide an improved motor vehicle door lock and in particular to improve the overall process sequence of manufacture in terms of its economy and quality.
- the invention provides that a connection counterpart formed from the side of the lock housing opposite the support plate is provided, which is intended for interaction through a passage opening in the support plate with a connection element on the vehicle door.
- the invention proposes to avoid the previously customary connection of a motor vehicle door lock with a direct connection between the motor vehicle door and the carrier plate itself, since this previously acted as a noise transmission bridge.
- the lock housing is made of a noise-damping material, the connecting element connecting the motor vehicle door lock to the motor vehicle door is not in contact with the carrier plate. This enables optimal noise reduction.
- connection counterpart is preferably formed by a conical tower.
- a dome-cone receptacle which is a funnel-shaped opening, is formed on the carrier plate on the side facing the lock housing around the access opening for interaction with the conical dome for receiving the conical dome.
- the dome-cone receptacle is preferably produced by extrusion coating which uses the so-called outsert technology.
- the plastic material is injected directly around the parts to be enclosed, edges, openings or projections on the metal carrier serving as anchoring or attachment for the plastic. An assembly of the injection molded parts on the carrier plate is therefore not necessary. This saves a lot of work steps and the materials for the otherwise occurring parts during assembly and time-consuming logistics and warehousing that otherwise have to be individually parts and parts to be delivered can also be saved.
- the outsert technology enables high-precision shapes to be produced that have very low tolerances. Since assembly is also omitted, the associated possible tolerances in the geometries are also avoided.
- An advantageous embodiment of the invention provides that a bearing for the thread of a screw extending through the through opening is formed in the connection counterpart.
- This bearing can be formed by a thread, but also by an opening in a material that enables the use of self-tapping screws as a connecting element.
- the carrier plate is advantageously made of a dimensionally stable material, in particular a metal.
- the locking parts are preferably a rotary latch and / or a pawl of a motor vehicle door lock.
- the carrier plate is at least partially provided on its outer edges and / or on the edges of openings or punched-out areas with a plastic encapsulation that envelops the edges, which plastic encapsulation is applied in particular by outsert technology.
- the overmolding of the edges also serves as corrosion protection, since the open punched or cut surfaces are sealed off by the air.
- the overmolding also means that material of greater thickness is used, the edges of which, due to the processing - for example punching - do not have the protective layer previously applied, for example a zinc layer.
- plastic overmolding in particular by outsert technology, is applied at least partially between the locking parts and the carrier plate and / or the lock case and / or the lock housing is.
- Such an encapsulation which is also applied externally, can, in addition to further damping, also achieve an improved design of the entire motor vehicle door lock.
- a variant that is efficient in terms of production provides that the plastic extrusion coating on the carrier plate is produced in a single manufacturing step using outsert technology.
- a transport lock for connecting the lock housing to the support plate is provided on the support plate, which transport lock has locking projections which are provided on an edge or a shape on the lock housing for locking.
- the lock housing and / or the conical dome and / or the transport lock are preferably made of a plastic, in particular a technical plastic and / or glass fiber or carbon fiber reinforced plastic.
- the carrier plate is advantageously formed by a lock case of a motor vehicle door lock.
- the lock housing enclosing the locking parts mounted on the carrier plate can also be produced in one piece.
- a damping layer is preferably provided between the motor vehicle door and the motor vehicle door lock, the damping layer being applied by means of a plastic encapsulation, in particular using outsert technology.
- FIG. 1 is a plan view from the front of a carrier plate which has dome-cone receptacles according to the invention for guiding the connection counterparts,
- FIG. 2 is a plan view of a lock housing with connecting counterparts protruding thereon
- FIG. 3 shows a top view from behind of an inventive motor vehicle door lock with the carrier plate from FIG. 1 and the lock housing from FIG. 2,
- FIG. 4 shows a top view from the front of the motor vehicle door lock from FIG. 3,
- 5 is a schematic sectional view through a lock housing and a carrier plate before assembly
- 6 shows a schematic sectional illustration through a lock housing and a carrier plate after they have been assembled to form a motor vehicle door lock
- FIG. 7 is a schematic sectional view through a motor vehicle door lock before it is placed on a motor vehicle door
- FIG. 8 is a schematic sectional view through a motor vehicle door lock after it has been placed on a motor vehicle door
- Fig. 9 is a schematic sectional view through a motor vehicle door lock on a motor vehicle door with connecting element
- Fig. 10 is a schematic sectional view through a motor vehicle door lock mounted on a motor vehicle door.
- FIG. 1 shows a schematic representation of a top view from the front of a metal carrier plate 4, in the example a lock case 31 of a motor vehicle door lock 3.
- bearing pins 1 for storing locking parts and two dome-cone receptacles 44 according to the invention protrude on.
- the dome-cone receptacles 44 have a funnel-shaped opening 45 for receiving the cone-shaped dome (see FIG. 2).
- the dome-cone receptacles 44 have been molded with plastic encapsulation 54 around through openings 43 (see FIG. 3) for a connecting element and have been produced using outsert technology.
- flat plastic overmoldings 52 were also applied, some of which serve as a sliding aid and noise damping between the locking parts and the carrier plate.
- edge 46 of the carrier plate 4 is provided with a plastic encapsulation 55, whereby this is sealed off from the air and a risk of injury from sharp-edged burrs is avoided.
- the rotary latch 21 and the pawl 22 are placed on the ends of the bearing pins 1 and pushed down against the carrier plate 4.
- FIGS. 9 and 10 show the lock housing 32 with the connection counterparts 34 formed on the side 36 of the lock housing 32 opposite the support plate 4, which are formed by conical projecting domes 35.
- the cone-shaped domes 35 each have a central bearing 37 for the connecting element (see later FIGS. 9 and 10).
- the illustration also shows the locking parts 2, in the form of a rotary latch 21 and a locking pawl 22 in the position which they assume on the bearing pins 1.
- the bearing pins are supported at their ends in the receptacles 33 of the lock housing 32.
- the rotary latch 21 and the pawl 22 are also partially covered with a plastic overmolding 53.
- FIG. 3 and 4 show a top view from behind and from the front of a fully assembled motor vehicle door lock 3 according to the invention.
- the lock case 31 carrier plate 4) with the locking parts 2 carried by it is enclosed by the lock housing 32.
- a damping layer 56 is formed around the access opening 43, which serves as noise decoupling between the motor vehicle door and the motor vehicle door lock 3 (see also FIG. 8).
- the damping layer 56 is formed by a plastic extrusion coating; in the example, this is the same plastic extrusion coating 54 from which the dome-cone receptacle 44 was formed.
- 5 to 10 show, in individual cross-sectional representations, schematically in exemplary individual situations, the assembly of a motor vehicle door lock and such on a motor vehicle door.
- plastic encapsulation 55 of the edges can be seen in section.
- the connecting counterpart 34 that is to say in the example the conical tower 35, which on the carrier plate 4 opposite side 36 of the lock housing 32 is formed, exactly opposite the through-opening 43 on the surface 42 of the support body 4, the dome-cone receptacle 44 on the support body 4 is formed using outsert technology. Through the funnel-shaped opening 45, the conical dome 35 is brought securely into its end position.
- the finished motor vehicle door lock 3 is placed on the sheet metal of a motor vehicle door 8, as shown in FIG. 7, when it is installed in a motor vehicle.
- the opening in the sheet metal of the motor vehicle door 8, the passage opening 43 and the bearing 37 for the connecting element lie in one line.
- the motor vehicle door 8 shows the motor vehicle door lock 3 placed on the sheet metal of the motor vehicle door 8.
- the motor vehicle door 8 is not in direct contact with the carrier plate 4.
- the damping layer 56 is located between the motor vehicle door 8 and the motor vehicle door lock 3 in order to dampen noise and prevent vibration.
- the damping layer is through the plastic extrusion 54
- the transport lock 9 with a projecting area forms a damping layer and the enveloping plastic encapsulation 55 of the edges. 9 shows the state shortly before the screw 71 as the connecting element 7 is introduced through the sheet metal of the motor vehicle door 8 and through-opening 43 in the carrier plate 4 into the bearing 37 of the connecting counterpart 34 molded out of the lock housing 32.
