Description

Kraftfahrzeugtü rsch Sweet

Description;

The invention relates to a Kraftfahrzeugfürversohluss, with a body ie- side lock housing and a hood ^« or door-side Schiießboizen. or vice versa and with a closing and / or opening device. The lock housing regularly comprises a key box and a lock cover, with the aid of the Schiosskasten is closed, in the Schiosskasten usually a locking mechanism is mounted, which is composed of a rotary fold, and a cooperating pawl. The rotary latch and thus the thus defined motor vehicle door lock interacts with the locking pin: in a known manner.

As usual, the lock housing can be arranged on the body side or hood or door side. In the former case, the naked housing is fixed to a motor vehicle body, for example by screws. The variant mentioned in the second corresponds to the fact that the lock housing and with it the Türschioss in the interior or on a door, a hood, a flap or the like is attached.

Consequently, a distinction is made in de practice, for example, side door locks, rear kiappenschiösser and hood locks or bonnet locks. All of these fall under the generic term motor vehicle door lock and in conjunction with the locking pin under the generic term power door verschiuss. In the context of the invention, the lock housing is regularly mounted on the body side, so it is found on an associated Krafffahrzeug body. In contrast, the Schließbötzen is connected to a hood, so that usually a Haubenschiöss or engine bonnet is considered. Reason- In addition, however, the procedure can be reversed. Then the closing bulb is connected to the body or motor vehicle body, whereas the lock housing and, with it, the motor vehicle lock undergoes an attachment to the hood or generally on the door side,

*>

In practice and in the generic state of the art according to EP 1 489 2S2 81, it is advantageous to work with closing and opening assistance devices which generally ensure that, after reaching a certain feed-forward position, the distance between the body and the hood or door to be closed is reduced (Sphließstellung). This is generally done by motor or by means of a motor drive, although in principle a mechanical closing or closing is possible and is included. In addition, in principle, opening devices are also known, with the aid of which the hood or motor vehicle in question is opened or the door or motor vehicle door 5 is opened or issued vis-à-vis the Krafrfahrzeug body. In principle, such closing devices can also be combined.

In general, however, it is usually worked only with a closing aid or, Schlie & ein-0 direction di which motor, for example, located in Vorraststeilung of the locking mechanism motor vehicle door in the Ha.uptraststellung. For this purpose, a rocker is applied in the generic state of the art according to EP 1 489 252 B1. The motor drive works on a toggle lever element with two toggle levers. In this way can also fish in case of failure of the moto-5. Drive a perfect mechanical operation of the locking mechanism are ensured in a mechanical closing operation. This has proven itself in recent times and in particular in so-called Haü.benschlössem, so raf car door locks on a motor vehicle hood or in the area of Kräftughzeughaube, now arise requirements to adjust a gap between the motor vehicle door or the motor vehicle ha übe and the vehicle body as small as possible wse possible and is possible to reduce to 0 mm or almost 0 mm. This requirement is explained not only due to aesthetic considerations that require a smooth surface as possible and closed surface for a modern motor vehicle. But the size of the gap has, especially in this area, immediate effects on air turbulences in the front area, which can negatively influence the air resistance depending on their formation and expression. At this point, so far lacking convincing solutions, Hie uses the invention.

The invention is based on the technical problem of further developing such a motor vehicle tour so as to be able to provide the lowest possible Spaitmaß between body and door or hood with simple means.

To solve this technical problem, a generic motor vehicle door lock is characterized in the context of the invention in that the closing and / or opening device ripens externally on the lock housing for its adjustment relative to a stationary base element in the course of a sliding opening

Since the lock housing is typically arranged on the body side, that is, on an automobile body undergoes an arrangement or is connected to the Krafffahr- convincing body, it is at the fixed base member is a part of this motor vehicle body. In general, the motor vehicle lock according to the invention is located in the region of an upper front carrier on the front of the motor vehicle body, which is typically arranged or runs horizontally. The design is advantageously made such that the Schiossgehäuse is connected to an axis or axis of rotation pivotally connected to the basic element in question. That is, the adjustment of the lock housing in the course of the closing-Zöffnungsvorganges corresponds to a pivotal movement of the lock housing to the questionable axis or axis of rotation. For this purpose, the axis or axis of rotation is generally defined in such a way that in the example case de upper front carrier of the vehicle body is equipped with a corresponding pin or pin on which the Schiossgehäuse is rotatably mounted.

In order to achieve a particularly stable design at this point, the Schlosskastert is generally rotatably mounted on the bolt in question. On the other hand, the lock cover is connected to the ski box and, as it were, will be replaced by a slewing movement of the lock box.

The described closing ZÖffnungsvorgang kan basically be made mechanically, this may work, for example, a Bowden cable on the closing and / or Öffnungsseihrichtung that can be operated manually Regelelfati, however, a motor drive for the closing and / or Öffnungsseinriehtung is provided. It has been proven that the motor drive works eccentrically on the SchJe & - / Öf opening device .. It is also advantageous if the motor drive only then acts on the closing and or opening device when the door lock is in its Hauptrasisteliung. In general, the closing and / or opening device essentially consists of a rocker and a pawl acting on the Schioss housing together. With the help of the rocker relatively large torques can be exerted on the lock housing, even if with a small working motor drive is working, which applies a rather small force.

The rocker is usually rotatably connected to the base member. In this case, it has proven useful if the rocker and the lock housing are connected coaxially rotatable to the base member. In this case, therefore, the bolt acts on the upper front support of the vehicle body advantageous as a common axis of rotation for one hand, the lock housing and on the other hand, the rocker. In addition, this is a particularly compact and Ö little sprawling construction provided.

The handle. In turn, is generally rotatably mounted on the sling. The latch may be biased by means of a spring. In addition, it has proven useful if the pawl engages a projection on the lock housing behind-5. This projection on the lock housing can be advantageously formed from rods around the lock case.

To operate the rocker and to pivot about the common axis of rotation with the lock housing, the rocker is largely equipped with a slot for engagement of an actuating pin. The actuating pin is in turn advantageously applied by means of the motor drive.

The design is regularly made so that the actuating pin 5 is arranged on a driven pulley. The driven pulley can be rotated by means of a motor or electric motor. The electric motor has on its output shaft via a worm, which engages in. An outer edge side toothing of the driven pulley to pivot about this counterclockwise or clockwise about an associated axis zu0. This results in movements of the actuating pin a circular arc, and indeed within the long hole of the swingarm. For the basic design of such a motor drive reference is made to DE 299 15 905 U1. That is, the actuating pin performs within the Langioehes the rocker initiated by the motor drive circular arc movements. In this way, the rocker and with it the lock housing can be pivoted about the common axis of rotation relative to the base member. For a pivoting movement of the wings also has the consequence that the Schlössge- home is taken over the pawl during the rotational movement of the rocker.

As a result, a driver's license is provided, which is particularly suitable for making small clearance widths between the associated door or hood and body available, which can be set to 0 mm or almost 0 mm. The invention achieves this in essence by the fact that with the help of the closing and / or opening device, the entire lock housing is pivoted relative to the base wire or an upper and mostly horizontally arranged front support of the raftfahrzeugkarGsserie. That is, the closing and / or opening device attacks. ^" Do not press against a ratchet stored in the associated castle Kasia.

Rather, the locking mechanism when closing the door or hood is first transferred to a Hauptschlseßsteliung or Hauptraststeliung. This position starts the closing or Sohließvorgang invention.

During this closing or closing operation, the entire lock housing is then pivoted about the axis of rotation with respect to the motor vehicle body with the locking mechanism located in the main catch and consequently with the locking bolt caught therein. This can be particularly sensitive and in comparison to a For example, take place at the Drelifaiie attacking Zuziehbewegung with much larger lever arms and correspondingly larger torques. As a result, practically any gap width between the door or hood and the motor vehicle! Rasserie can be realized, which extend down to 0 mm or nearly 0 mm. All this takes into account a simple and functionally correct structure. Here are the main advantages , In the following, the invention will be explained in more detail with reference to a drawing showing only an example of an embodiment; show it:

Fig. 1 the Kraftfahrzeug Türschuuss invention when open

Hood in Beisp elfali and Fig. 2 the object of Fig. 1 in the state of the closed

Hood.

In the figures, a motor vehicle Türverschiuss is shown, the first time in its basic structure on a Karosseheseitiges Schioss- housing 1 and a hood-side locking pin 2 has. That is, the SchSießbolzen 2 is connected to a dashed line indicated hood respectively hood 3. That is, it is in the present case a hood lock, which of course is not restrictive. The body-side mounting or arrangement of the Schfossgehäuses 1 is shown in FIGS. 1 and 2 such that there is only indicated an upper front carrier 4 as part of the motor vehicle body 4. The front carrier 4 is equipped with a recess 5, which receives in its interior the body-side lock housing 1, The lock housing 1 is in principle composed of a lock box 1a shown and a lock cover connected or connectable to the lock case 1a, but which is not shown. While the lock case 1a is designed to be metallic and solid in order to accommodate a locking mechanism 8, 7 mounted therein, the ski cover, not shown, is typically made of plastic. The locking mechanism 8, 7 is composed as usual of a rotary latch 8 and a pawl 7, which are each rotatably received in the lock case 1a, as compared to FIGS recognize the figures.

For further basic construction includes a closing and / or opening device 8, 9. The closing and / or opening device 8, 9 is in AusfÐrungsbeispiei and not restrictive designed as a closing aid 8, 9 and sets up of a rocker 8 and a Jack 9 together. In addition, a motor drive 10, 11 is shown. The motor drive IQ, 11 is composed of a Abtnebscheibe 11 and arranged on the driven pulley 11 actuating pin 10 together. Actiich the actuating pin 10 is predominantly perpendicular to the driven pulley 11.

The driven pulley 11 is in turn by means of a not explicitly shown electric motor in rotation about an axis 12 in the clockwise direction and in the. Offset counterclockwise. For this purpose, an output shaft of the electric motor is equipped with a worm which engages in an external toothing of the driven pulley 11. The output disk 11 performs during the transition from the functional position of Fig. 1 for Funktionsstejiung of FIG. 2, a clockwise rotation about its axis 12, taking into account a circular arc of about 180 °, which describes the co-moving actuating pin 10. Of particular importance for the invention is the fact that the closing and / or Öffhungseinrichtung 8, 9 or the invention provided Zuzsehhüfe 8, 9 outside of the Sehlossgehäuse 1 for adjusting the Schiossgehäuses 1 relative to the stationary base element 4 in the course of a closing ZÖffnungsvorganges attacks. For this purpose, the pawl engages or engages behind a projection 13 on the lock housing 1 or a projection 13, which is presently formed in or on the lock case 1a. The motor drive 10, 11 operates as a whole eccentrically on the closing and / or opening device 8, 9, as can be seen in the comparison of Figures 1, and 2. For this purpose, the actuating pin 10 engages in a tang och 14 in the rocker 8 a. In fact, the actuating pin 10 passes through the respective Langioch 14 in the rocker. 8

The rocker 8 is rotatably connected to the base member 4. The same applies to the lock housing 1, In the case of the embodiment, a design is pursued in which the rocker 8 and the lock housing 1 are connected coaxially to the base housing 4 in question. For this purpose, a bolt 15 is provided, which is anchored in the base member 4 and the front support 4 realized at this point. On this stationary bolt 15, both the rocker 8 and the lock housing 1 and the Schlosskasfen 1 a are rotatably mounted. The design may be made such that the rocker 8 is arranged in the illustrated plan below the lock housing 1 and consequently also below the Schiosskastens 1a, This also applies to the pawl 9, which in turn is rotatably mounted on the rocker 8. For this purpose, a further bolt 18 is provided. The projection 13 may extend so far in this design that it can be over-tightened by the pawl 9 or behind.

The operation is as follows, in FIG. 1 is the erfindungsge.mäSe motor vehicle pestle and consequently the associated hood 3 in position To close now the hood 3, this is manually lowered so far relative to the body 4 and the front carrier 4, that the attached to the hood locking bolt 2 as usual in the Dre.hfäile 6 or ei there inlet mesh 16 retracts. As a result, the rotatable tubing 6 is pivoted clockwise about its axis until it finally reaches its main latching position shown in FIG. In the main locking position, the pawl 7 falls into the catch 6 and prevents the catch 6 pivots spring-assisted and releases the captured Schließboizen 2. In the main locking position of the locking mechanism 6, 7, the hood 3 still has a significant gap S with respect to the body 4 or the front carrier 4, as indicated in FIG. 1. For the closing and / or opening device 8, 9 or the Zuziehhiife 8, 9 according to the invention is in its ready position. Furthermore, the Schioss housing 1 is swung out as against the body 4. In addition, the motor drive 10, 11 in this position ensures that the hood 3 or the Schließboizen 2 can not spring through. That is, the hood 3 or the locking bolt 2 certainly reaches the main locking position of the locking mechanism 8 "7 according to FIG. 2. The main locking position is in turn interrogated with the aid of a sensor, for example a switch. As a result, the motor drive 10, 11 is acted upon starting from the standby position according to FIG.

As soon as the motor drive 10, 11 has received the start signal from the sensor or switch in question at the locking mechanism 8, 7, namely that the locking mechanism 8, 7 is in the main locking position, the electric motor is energized. This results in a movement of the driven pulley 1 1 clockwise about its axis or axis of rotation 12. The the slot in the rocker 8 by cross-actuating pin 10 accordingly acts on the rocker 8 and the closing 8. 9. eccentric total. In doing so, the operator completes 10, a total of approximately 180 "circular arc movement, as seen in the transition from Fig. 1 to Fig. 2.

2, the actuating pin 10 has moved from an upper edge of the Langioches 14 to the opposite lower edge and at the same time pivots the rocker 8 about its axis or axis of rotation 15 in the counterclockwise direction. Since in this entire process, the pawl 9 has held the Schioss housing 1 on the projection 13 and, moreover, the pawl 9 is rotatably mounted on the rocker 8 and is moved with this, also performs the Schiössgehäuse 1 a counterclockwise movement about the common axis 15 with the rocker 8 during the transition from FIG. 1 to FIG. 2, for this purpose the tightening process corresponds. The SchiieSbewegung of the lock housing 1 and the rocker 8 takes place against the force of a spring 17. The spring 17 is a coil spring which is attached at one end to the bolt connected to the body 4 15, while the other free End of the coil spring 17 biases the lock housing 1, in a clockwise direction with respect to the axis or axis of rotation 15th

An end stop or stop buffer 18 on the body provides for the described closing process for a cushioning. Because when reaching the Schiießstellung or pulled position shown in FIG. 2, the counterclockwise about the axis 15 by means of the motor drive 10, 11 pivoted rocker 8 abuts against the stop or stop buffer 18 in question. Then the hood 3 is completely closed relative to the body 4, to which a minimum gap S corresponding to the illustration of FIG. 2 corresponds. W

In FIG. 1, a pyrotechnic element 19 is then represented by an arrow. This ensures that the hood 3 can be set up in an accident. For this purpose, the pyrotechnic element 19 operates on the pawl to wegzüschwenken this from Vorsprang 13 on the lock housing 1.
