Definitions

  • the invention is directed to a closure of the type specified in the preamble of claim 1, the lock comprises a rotatably mounted latch and a pivot-mounted pawl.
  • the rotary latch When closing the door, the rotary latch is transferred from the closing element from its open position initially in a Vorrastlage, which is secured by the pawl. Then, the catch is rotated further either manually or by motor into a Hauptrastlage, which is also secured by the pawl. Sensors are to monitor different working positions of the lock links.
  • the DE 103 27 997 A1 shows a known closure of this type, where the further rotation of the rotary latch is effected by motor from its pre-locking position in the main locking position.
  • the lock of this known closure uses only one pawl, which is incident either in a pre-rest or in a main catch of the catch.
  • a closing aid is used, which drives a pair of knee lever levers via a motor-driven eccentric, engages at the free end of a resilient driver.
  • the pair of knee lever levers is fixedly mounted at one end and forcibly guided by guide means at the other end. The closing movement is achieved by stretching and bending the knee lever pair. This closing aid is space consuming.
  • the invention has for its object to better monitor the respective working position of the lock members and evaluate reliable. This is achieved by the measures specified in claim 1, which have the following special significance.
  • the invention initially proposes two separate pawls, of which the first pawl acts only on the pre-catch and should therefore be referred to below as "pre-catch".
  • the second pawl is arranged separately from it and only attacks the main catch, which is why it is called “main pawl”.
  • the one monitors, directly or indirectly, only the main pawl to determine whether it is in its position of incidence or in its release position with respect to the main catch of the catch. Because of this, this first sensor is called the "main moment sensor”.
  • the other sensor determine directly or indirectly via one or more intermediate members, the position of incidence and the release position of the pre-locking pawl on the pre-catch of the rotary latch and thus acts as a "pre-scan". It is easiest if the sensor carries out the monitoring directly at the associated pawl. Alternatively, however, an indirect monitoring of the respective latch via one or more intermediate links is possible by e.g. between the sensor and its pawl sets a control lever.
  • the closure consists of a lock which, with its lock housing 11 shown in the figures, is attached to a lock Fig. 1 dash-dotted lines indicated tailgate 12 of a vehicle is attached.
  • a cooperating with the lock closure element 10 is fixed to a in Fig. 1 also dash-dotted illustrated vehicle body 13 is arranged.
  • the closing element 10 can consist of the one bar leg of a U-shaped element or of a bolt.
  • a rotary latch 15 which is mounted on a stationary in the lock housing 11 axis of rotation 14.
  • the rotary latch initially has a receiving slot 16 for the closing element 10 and two spaced shoulders 17, 18 on its contour profile, which act as a pre-catch 17 and as a main catch 18.
  • the catch 15 can take different rotational positions in the different phases of the castle, which are shown in the figures.
  • Fig. 1 is the rotary latch 15 in a marked by an auxiliary line 15.1 open position. Then the flap is fully open.
  • the rotary latch 15 is loaded by a spring force not shown in detail, which endeavors, the rotary latch 15 in the direction of the arrow 19 of Fig. 1 to be pressed against a stop not shown in detail. By the force load 19 and the stop, the clarified by an auxiliary line 15.1 open position of the rotary latch 15 is determined.
  • the Vorrastklinke 20 is supported with a support surface 26, which leads the radially positioned support point 21, on a peripheral contact surface 24 of the rotary latch 15 from.
  • This support 26, 24 takes place in Fig. 1 area.
  • the contact surface 24 has, based on the axis of rotation 14 of the case 15, a large circle of curvature 25.
  • the support at 26, 24 comes about because the Vorrastklinke 20 is under a spring load, the in Fig. 1 is illustrated by a force arrow 23.
  • the pre-locking pawl 20 is mounted in the present case on a special, movable pivot axis 22, which will be described in more detail.
  • the pawl support surface 26 is located at a radial distance from the catch abutment surface 34; There remains a gap 27 there.
  • the catch 15 either by further manual compression of the tailgate 12 or motor, as in the illustrated embodiment, in a by the auxiliary line 15.3 of Fig. 3 and 4 illustrated Hauptrastlage be transferred. Then the tailgate 12 is fully closed. The closing element is then penetrated even deeper into the lock housing 11 and is held particularly reliable by the rotary latch 15.
  • the main locking position 15.3 is secured by a second pawl 30, which is mounted on a stationary pivot axis 32 in the lock housing 11.
  • the pawl 30 is supported by a locking point 31 on the described main catch 18 of the rotary latch 15. Therefore, as has been said, the pawl 30 "main pawl" will be referred to.
  • the main catch pawl 30 is supported on a second circumferential abutment surface 34 of the rotary latch 15, which, relative to the axis of rotation 14 of the rotary latch 15, has a smaller radius of curvature 35 than the first abutment surface 24 described above.
  • the main pawl 30 is under a by the force arrow 33 in Fig. 1 illustrated spring load. This spring load 33 ensures that in the above rotation of the rotary latch 15th the locking point 31 at the end of its peripheral abutment surface 34 behind the main catch 18 incident, as it Fig. 2 shows.
  • the working lever 41 may have an angular course. At the free end 43 of the working lever 41 engage drive means not shown in detail of the closing aid 40.
  • a special feature of the invention is that the already mentioned pivot axis 22 of the latching pawl 20 is seated on the working lever 41 and is therefore moved during the working movement of the lever 41. This co-movement is from the transition of the catch 15 of Fig. 2 in Fig. 3 to recognize, with the Fig. 3 shows the last phase of this entrainment movement.
  • Fig. 2 is the working lever 41 still in its illustrated by an auxiliary line 41.1 starting position.
  • By the drive means of the working lever 41 is about its pivot bearing 42 up to his Fig. 3 recognizable end position further rotated, which is illustrated there by an auxiliary line 41.2.
  • the extent of rotation is in Fig. 3 recognizable by a rotary arrow 44.
  • This rotation 44 causes the rotary latch 15 is further rotated by a corresponding angular amount 45 about its axis of rotation 14.
  • the Fig. 3 shows, as has already been said, the final state of the closing movement, namely the main latching position 15.3 of the rotary latch 15, where its locking point 31 has already fallen behind the main catch 18.
  • the lock-side drive means for this trap rotation 45 are the same, which for their pre-described Vorrastlage 15.2 in Fig. 2 ensure, namely the Vorrastklinke 20 and its pivot axis 22 on the working member 41.
  • the Vorrastklinke 20 thus has the other function at the same time To be drive means of the closing aid 40. From Fig. 2 on until Fig. 3 is the locking point 21 of the latching pawl 20 with the pre-catch 17 of the rotary latch 15 in engagement. Upon further rotation 45 of the rotary latch 15 so both functions not only the same components, but also the same engaging means 17, 21 are active.
  • the various working positions of the lock elements are monitored and controlled via a control unit which interacts with a plurality of sensors 51 to 53.
  • sensors 51, 52 are provided, of which the first 51, the Vorrastklinke 20 and the other 52, the main pawl 30 monitor.
  • the monitoring of the two pawls 20, 30 can be done either directly, as shown in the embodiment, or indirectly, for example by a transmission lever not shown in detail.
  • the sensor 51 monitors whether, based on its pivot axis 22, the pre-locking pawl 20 in its release position 20.1 of Fig. 1 or in its incidence position illustrated by the auxiliary line 20.2. The same applies to the second sensor 52.
  • the sensor 52 determines whether with respect to its pivot axis 32 in its release position 30.1 to the main rotary latch 18 according to Fig. 1 and 2 or in its position of incidence 30.2 according to Fig. 3 and 4 located where the catch 15 is supported on the main catch 18.
  • a third sensor 53 which indirectly or directly monitors the rotational position of the trap 15 in an analogous manner.
  • the sensor 53 engages directly on the rotary latch 15 and monitors whether they are in the open position 15.1 of Fig. 1 or in the main lodge 15.3 of Fig. 3 or 4 located. It is understood that, if necessary, alternatively or additionally, other rotational positions of the case 15 could be monitored, for example the pre-locking position 15.2. However, this is dispensable in the present embodiment, because this monitoring, as already mentioned, is concerned by the first sensor 51.
  • the three sensors 51 to 53 consist of electrical micro-switches, each one of the best Fig. 4 apparent switching element 54 to 56 have.
  • the switching elements 54 to 56 strive in their off Fig. 4 apparent Ausfahrlage to arrive, each one their Ausschaltlagen corresponds.
  • the sensors 51 to 53 are connected via respective ports 57 to 59 to the aforementioned electrical control unit.
  • the control unit receives from all three sensors 51, 53 each have a switch-off signal "zero". If one writes the signals received by the sensors 51 to 53 in the main locking position on the control unit in a digital code, this is 0/0/0.
  • the control unit thus determines via this code that the pre-latching pawl 20 is in the incidence-ready incidence position 20.2, furthermore the main latching pawl 30 is in its effective incidence position 30.2 and finally the catch 15 is in its main latching position 15.3.
  • the signals coming from the three sensors 51 to 53 in positions 15.1, 15.2 and 15.3 are shown in three diagrams of Fig. 6.1 to 6.3 illustrated.
  • the Fig. 6.1 shows the signals at the associated terminal 57 of the first sensor 51.
  • the abscissas in the three diagrams are the time scale, which are aligned with each other at the time of departure, as the time line t 1 shows.
  • the three ordinates of Fig. 6.1 to 6.3 show the two alternative switching signals incurred at their aforementioned terminals 57 to 59, namely either the turn-on signal 1 or the turn-off signal 0.
  • the connecting line t 1 shows the timing of the open position 15.1 of the rotary latch. From this line t 1 it can be seen that in the open position 15.1 of the rotary latch, a digital code 1/1/1 applies to the three sensors 51 to 53.
  • the three sensors 51 to 53 in the main latching position 15.3 of FIG Fig. 3 and 4 the digital signals 0/0/0 to the electrical control unit.
  • the exact time t 3 from the control unit can be recognized by the fact that the second sensor 52 is just switching from the switch-on signal 1 to the switch-off signal 0.
  • the control unit registers this in Fig. 6.2 with 37 marked code changes. It is significant that the signal 0 of the Vorrastsensors 51, which is obtained in the Vorrastlage 15.2 of the rotary latch 15, during further rotation of the rotary latch 15 to the Hauptrastlage 15.3 does not change. The signal 0 remains.
  • the third sensor 53 functions as a so-called “snow load sensor", which only has to determine whether the open position 15.1 of the lock of Fig. 1 present or not.
  • a snow load could ensure that the rotary latch 15 remains in its main latching position 15.3 even when the associated main latching pawl 30 has released its main catch 18 due to the snow load weight.
  • the rotary latch 15 is pressed in this case to the closing element 10.
  • Fig. 5 shows the initial phase when opening the fully closed tailgate, where the catch 15 is just in its main rearing position 15.3, although the corresponding pawl 30 with its locking point 31, the latch main catch 18 has already released.
  • a common, not shown in detail release lever serve, both the main pawl 30 and the Vorrastklinke 20 in the sense of in Fig. 5 drawn pivot arrows 28 and 38 moved back from their incidence positions 20.2 and 30.2 in their respective release position 20.1 and 30.1.
  • the catch 15 of both pawls 20, 30 free and can due to their mentioned force load 19 up to their dash-dotted lines in Fig. 5 illustrated open position 15.1 are turned back.
  • This reverse rotation of the trap 15 is in Fig. 5 illustrated by a dotted pivot arrow 49.
  • the aforementioned common release member for both pawls 30, 20 could sit on the bolt of the pivot axis 32 of the main latch 30 and be designed as a common release lever.
  • This release lever then has two effective locations, which act on the two pawls 20, 30 in the sense of the described pivoting operations 28, 38. It is understood that one could alternatively use two separate release members.
  • a common release member, which is only on a latch, e.g. the main pawl 30 engages, could be used for the described release operation 28, 38, even if the one pawl, e.g. the main pawl 30, the other pawl, that would then the Maurastklinke 20, partially overlapped. The overlap thus transfers the movement of one pawl 30 to the other 20.
  • the release member not shown in detail is manually operable in the present case, for example via a provided on the tailgate handle. But this could also be done by motor, via a so-called "opening aid".
  • the two pawls 20, 30 are motorized in the sense of the release arrows 28 and 38 of Fig. 5 pivoted.
  • the release member involved in this excavation 28, 38 would then be a motor-driven motor release member driven by the motor.
  • the Vorrastklinke 20 is associated with a stop 46, which is formed for example by a stationary in the lock housing 11 arranged block 47.
  • This stop 46 is located at a short distance from the front end 48 of the Vorrastklinke 20. If it is in this off Fig. 2 apparent Vorrastlage 15.2 should come to a crash, the latch 20 can be supported on the stop 46.
  • the closing element 10 in the rotary latch 15 act in the sense of the force arrow 50 of Fig. 2 illustrated crash forces that can be transferred from the Vorrastklinke 20 via the surfaces 48, 46 on the stationary block 47.
  • crash forces 50 act essentially in the longitudinal direction of the pre-locking pawl 20 and are derived via the block 47 on the lock housing 21 and thus the tailgate 12. This gives a high crash safety, without having to provide for a correspondingly high strength of the lock parts, which is noticeable in small dimensions, a weight saving and small footprint.
  • the main pawl 30 is positioned opposite to the pre-locking pawl 20 in opposite directions.
  • Fig. 4 shows, the main pawl 30 is under pressure in the main rearing position 15.3, because the catch 15 is supported with its main catch 18 at the locking point 31.
  • the supporting force is transmitted in the longitudinal direction of the main pawl 30 on the pivot axis 32.
  • Fig. 2 it can be seen, however, is the pre-locking pawl 20 in the Vorrastlage 15.2 of the rotary latch 15 train loaded.
  • the locking point 21 of the Vorrastklinke 20 engages behind the Vorrast 17 of the rotary latch 15.
  • the two pawls 30, 20 are with their, the respective locking points 21, 31 having free ends facing each other and directed away with their pivot axes 22, 32 from each other.
  • the lock according to the invention in two different applications.
  • One application would be a comfortable servo lock, where the above-described closing aid 40 is integrated.
  • the other application would be a simplified standard lock used without the closing aid 40.
  • the operating lever 41 described together with its motor drive. Because it dispenses with a Vorrast 17 in such a standard lock, and the Vorrastklinke 20 can be omitted.
  • only the main catch 18 is used in the standard lock.
  • the rotary latch 15 and the main latch 30 remain, optionally with one or both associated sensors 52, 53. Modification of the components 15, 30 in the standard lock is dispensable.
  • the simultaneous use in a standard and servo lock makes it possible to produce these components in very large quantities, which manifests itself in low production costs.

Fermeture selon la revendication 10, caractérisée en ce que dans le cadre de sa fonction d'accessoire de fermeture (40), il est possible de libérer de sa position de précrantage (15.2) le cliquet de précrantage (20) en toute phase de son mouvement motorisé, et le cliquet permet d'ouvrir la porte ou le hayon (12) aussi en cas de défaillance du moteur.
  12. Fermeture selon la revendication 9, 10 ou 11, caractérisée en ce que l'organe de travail est un levier de travail (41) tournant sur palier (42), levier qu'attaque le moteur de l'accessoire de fermeture (40),
    et en ce que le moteur peut faire tourner (44) le levier de travail (41) d'une position de départ (41.1), qui définit la position de précrantage (15.2) du pêne tournant (15), vers une position finale (41.2) dans laquelle le pêne tournant (15) se trouve dans sa position de crantage principal (15.3).
  13. Fermeture selon la revendication 12, caractérisée en ce que le levier de travail (41) possède un palier tournant (42) à emplacement fixe.
  14. Fermeture selon la revendication 13, caractérisée en ce que le palier tournant (42) du levier de travail (41) coïncide axialement avec l'axe de rotation (14) du pêne tournant (15).
  15. Fermeture selon l'une des revendications 1 à 14, caractérisée en ce qu'une butée (46) à emplacement fixe est agencées dans la serrure à côté du cliquet de précrantage (20),
    en ce que le cliquet de précrantage (20) s'appuie en cas de collision contre cette butée (46),
    et en ce qu'en cas de collision cette butée (46) déleste le palier pivotant (22), situé contre le levier de travail (41), du cliquet de précrantage (20).
  16. Fermeture selon l'une des revendications 1 à 15, caractérisée en ce que la même serrure est utilisable à titre d'alternative dans deux cas d'application différents,
    à savoir - dans le premier cas d'application - comme serrure servocommandée à accessoire de fermeture intégré (40), en exploitant le précran (17) et le cran principal (18) du pêne tournant (15)
    ou - dans le deuxième cas d'application - comme serrure standard sans accessoire de fermeture (40), là où manque l'organe de travail avec le cliquet de précrantage (20) en appui contre lui sur palier pivotant et où seul est utilisé le cran principal (18) du pêne tournant (15).
  17. Fermeture selon l'une des revendications 1 à 16, caractérisée en ce que les capteurs (51 à 53) sont raccordés à un appareil de commande électrique
    et en ce que les capteurs (51 à 53) informent l'appareil de commande par des signaux numériques d'allumage et d'extinction (1 ; 0) sur l'état d'ouverture/fermeture des organes surveillés (20, 30, 15) de la serrure.
  18. Fermeture selon la revendication 17, caractérisée en ce que le signal (0), généré par le capteur de précrantage (51) lorsque le pêne tournant (15) se trouve en position de précrantage (15.2), n'est pas modifié pendant que le pêne tournant (15) continue de tourner jusqu'en position de crantage principal (15.3).
  19. Fermeture selon l'une des revendications 1 à 18, caractérisée en ce qu'un troisième capteur (53) attaque le pêne tournant (15) et détermine si le pêne tournant (15) se trouve ou non dans sa position de crantage principal (15.2)
    et en ce que ce troisième capteur (53) peut servir de capteur dit « de charge de neige ».
  20. Fermeture selon l'une des revendications 17 à 19, caractérisée en ce que le signal (1), généré par le capteur de crantage principal (52) lorsque le pêne tournant (15) se trouve en position ouverte (15.1), n'est pas modifié, pendant que le pêne tournant (15) continue de tourner, jusque peu avant d'avoir atteint la position de crantage principal (15.3).
  21. Fermeture selon l'une des revendications 17 à 19, caractérisée en ce que le signal (0), généré par le troisième capteur pendant que le pêne tournant (15) se trouve en position de précrantage (15.2), n'est pas modifié pendant la poursuite de rotation jusque sur la position de crantage principal (15.3) incluse.
  22. Fermeture selon l'une des revendications 17 à 21, caractérisée en ce que les signaux d'allumage et d'extinction (1 ; 0) provenant des capteurs (51 à 53) définissent, lorsque le pêne tournant (15) se trouve en position de précrantage (15.2), en position de crantage principal (15.3) et le cas échéant en position ouverte (15.1), trois codes numériques (0/1/0), (0/0/0), (1/1/1) qui diffèrent les uns des autres.
  23. Fermeture selon la revendication 22, caractérisée en ce que l'appareil de commande réagit au changement (36) de code d'au moins un capteur (51, 52), entre le code de position ouverte et le code de précrantage et constate ainsi clairement la position de précrantage (15.2) exacte du pêne tournant.
  24. Fermeture selon la revendication 22 ou 23, caractérisée en ce que l'appareil de commande réagit au changement (37) de code entre le code de la position de précrantage et le code de crantage principal des capteurs (51 à 53), et qu'il constate ainsi clairement la position de crantage principal (15.3) exacte du pêne tournant (15).
