Definitions

  • the present invention relates to a lock unit comprising at least one rotary latch with a main catch and a pre-catch, wherein the rotary latch is movement-blocked with at least one pawl in the closed state.
  • the invention finds particular application in motor vehicles for locking doors, flaps, etc.
  • Such lock units can be used in different embodiments. So it is possible, for example, that the blocking of the catch on the main branch with a pawl alone, in which therefore the arrangement of the catch and pawl is chosen so that z. B. the contact force between the catch and pawl through the Sperrklinkendrchachse passes. But there are also known variants in which the pawl is not able to lock the catch alone in the main catch position. This is especially true in case when the catch is biased by a spring so that it always wants to pivot in the open position.
  • the arrangement between pawl and rotary latch is such that the contact force between the two locking components does not pass through the pawl rotation axis, but has a component radially outward and thus pushes the pawl.
  • an additional blocking lever can be provided which blocks the opening movement of the pawl.
  • lock units which are designed with a so-called Schlosszuzieh Bü. With such a closing aid is achieved that, when the catch is in the pre-locking position, the catch by means of a drive, in particular an electric motor, in their position main-latch " is actively pivoted, for example, while overcoming the force that is required when closing the door against the door seal.
  • the closed position of such a lock unit so if the pawl is applied to the main catch of the catch to capture and then turn on and off various functions of a motor vehicle.
  • door opening lights in the dashboard can be switched on or off.
  • the automatic vehicle interior lighting can also be controlled via the specific position or positions of the locking components and in particular the rotary latch and / or the pawl.
  • even an engine start is only possible if it is ensured for all doors that all lock units have reached their closed state in the motor vehicle.
  • a lock unit is to be specified, with the one hand, a safe operation of the lock unit is ensured even in an automotive application, on the other hand, a safe and easy position detection for the current situation of Gesperres is possible.
  • the lock unit should be designed structurally simple.
  • the lock unit comprises at least one catch with a main catch and a first catch and a first pawl and a second pawl, wherein the first pawl cooperates with the catch on the main catch and the second pawl with the catch on the Vorrast, wherein position detecting means for both pawls are provided.
  • this lock unit according to the invention, it is assumed that the securing of the rotary latch in the two locking positions (“pre-restraint” and “main lock”) is carried out by different pawls, each separately and relative to one another.
  • the pawls can also be provided that they can fulfill other functions in addition to the locking of the catch in one position, so that e.g.
  • the second pawl is also designed as a release lever, which therefore acts on an actuating element.
  • pre-restraint is in particular a contour and / or elevation of the rotary latch (in the circumferential direction) defined, with which the catch can be locked in a position between the open position and the closed position, while still the exit of the locking pin from an inlet mouth the lock unit prevents. From this pre-rest position, the lock unit can be further rotated by the operator and / or drive until it reaches the position it occupies in the locked state ("main lock"). In order to ensure now sure that the first pawl cooperates with the main catch, the catch can also be a little over-turned, in a so-called overstroke position. Thus, the first pawl particularly low noise and low force before the main branch, in particular a contour or elevation of the rotary latch (in the circumferential direction or transversely thereto), proceed and come there when the return of the catch.
  • the position detection means are now used to detect a specific position for both pawls. This is in particular deduced to determine more than 2 states (open, pre-rest, main rest) for the individual pawl. On the contrary, the detent positions per pawl (s) are reduced here to obtain simple and accurate results with the position detecting means.
  • a common position detection means for both pawls is provided.
  • the areas facing away from the catch of the two pawls cooperate with a common position detection means.
  • “Together” in this context means that the position detection means is arranged so that both positions of the pawls can be detected and correlated with each other.
  • the common position detection means is locally spatially significantly limited and may optionally have its own housing.
  • the common position detection means is in particular an independent metrological apparatus which, in particular temporarily realized a physical contact towards the first pawl and / or the second pawl.
  • the common position sensing means comprises a push button switch.
  • the detection of the positions of the pawls via pushbutton leads to a very robust arrangement with clearly identifiable signals, because they regularly know only 2 states: active, not active. Logically interconnecting these signals with each other (e.g., via suitable electrical conductors) thus providing a simple common position detecting means.
  • the common position detection means is designed in the manner of a so-called double microswitch.
  • double microswitch two parallel contact lugs used as tactile elements, which cooperate with a corresponding Tastkontur the first pawl and the second pawl.
  • the double microswitch already comprises a logic with which from the electrical signal of the double microswitch a single, redundant signal, for example, to a control of the motor vehicle and / or the lock unit is forwarded.
  • the first pawl are mounted in a first plane and the second pawl in a second plane on a common pawl rotation axis.
  • a very compact construction of the locking mechanism can be achieved, wherein due to the optionally overlapping pivoting movement and the position or design of the common position detecting means can be kept very small.
  • the rotary latch and the first pawl in a first plane and (only) the (protruding) pre-catch of the rotary latch and the second pawl are arranged in an adjacent, parallel plane.
  • the two pawls are mounted in this preferred variant on a common pawl rotation axis against each other rotatable.
  • the common position detection means is arranged so that it is inactive in the state of the lock unit, in which the first pawl with the catch cooperates via the main catch.
  • the common position detection means for example in the manner of a push-button switch, is arranged so that there is no contact with the pawls in the closed state of the lock unit. In this way, in particular the mechanical load of the common position detecting means can be reduced, whereby the service life for such a common position detecting means is regularly increased.
  • the invention finds application in a motor vehicle, in which at least one such lock unit, z. B. in doors and / or flaps, is provided.
  • Fig. 1 is schematically and perspectively a locking mechanism of the catch 2, the first pawl 5 and the second pawl 6 is shown, which is arranged for example in the housing of a lock unit 1.
  • the rotary latch 2 is shown on the right in its closed position, in which the catch 2 with the first pawl 5 in the "main load” position is in operative engagement.
  • the first pawl 5 is rotatably mounted on a pawl rotation axis 11, wherein on the same pawl rotation axis 11 and the second pawl 6 is arranged.
  • first pawl 5 and the rotary latch 2 are arranged substantially in a first plane 9 and thus cooperate with each other in particular via their peripheral surfaces
  • the second pawl 6 is arranged in a second plane 10 located above it.
  • an arrangement is provided in which the second pawl 6 can pivot over portions of the rotary latch 2.
  • An interaction of the second pawl 6 and the catch 2 is now carried out in such a way that the catch 2 realizes a preliminary catch with a survey in the second level 10, which is used as a stud socket 24 in the right corner of Fig. 1 can be seen.
  • the first pawl 5 is secured in this closed situation with a blocking lever 15, so that the first pawl 5 is permanently in contact with the rotary latch 2. Accordingly, the first pawl 5 must be pre-released from the blocking lever 15 before the rotary latch 2 can pivot in the direction of the open position. The pre-release of the blocking lever 15 via the second pawl. 6
  • a common position detection means 7 is provided for the two pawls which are mounted on the common pawl shift axis 11.
  • the position detection means 7 is designed in the manner of a so-called double microswitch 21, which has a first contact lug 22 and a second contact lug 23.
  • the two parallel arranged contact lugs 22, 23 act as tactile elements temporarily with a respective corresponding Tastkontur 20 of the first pawl 5 and / or the second pawl 6 together.
  • the double microswitch 21 is arranged opposite to the pawl rotation axis 11 opposite the catch 2 and scans the current position or position of the first pawl 5 and / or second pawl 6 on the Tastkonturen 20 of the two pawls. In this way, as in particular with reference to the sequences of movements explained below, the current latching positions of the lock unit 1 can be determined reliably and redundantly.
  • Fig. 2 and Fig. 3 Now show a variant of the locking mechanism of a lock unit in the position "main load".
  • Fig. 2 are both, overlapping pawls 5, 6 shown in Fig. 3 the second pawl 6 is omitted to illustrate the position of the first pawl 5.
  • the rotary latch 2 is here in the closed position, in which this rests with its main catch 3 on the first pawl 5. It can be seen that the contact surfaces are designed so that the spring-loaded rotary latch 2 performs an opening moment on the first pawl 5, because the contact force does not pass through the pawl rotation axis 11.
  • the blocking lever 15 To secure the first pawl 5 on the main catch 3 is therefore the blocking lever 15, the movement blocking the first pawl 5 by a corresponding stop.
  • the second pawl 6 now has a driver 18 which bears against the blocking lever 15.
  • the contact of the blocking lever 15 is released to the first pawl 5 and the catch 2 pushes the first pawl of the main catch 3 independently.
  • the common position detection means in the manner of a push-button 8 is executed.
  • this is designed in the manner of a double microswitch 21 with contact lugs 22, 23.
  • the position of the first Pawl 5 and second pawl 6 in this closed position is such that the key switch 8 is inactive, so no force is applied to the key switch 8 through one of the two pawls.
  • FIG. 5 now show the position "Vorrast". This position assumes the locking especially during the closing process, for example, if the door is pressed with insufficient force against the door seals of a motor vehicle.
  • the first pawl 5 has not yet reached the main catch 3 of the rotary latch 2, but it is located at a different location on the peripheral region of the rotary latch 2 and / or in a receptacle 19 of the blocking lever 15. Nevertheless, it turns out Fig. 5 in that the first pawl 5 in this deflected position acts on the part of the pushbutton 8 provided for this pawl, so that it is activated.
  • a defined position detection is now achieved in that the second pawl 6 is not in engagement with the push-button switch 8.
  • both the first pawl 5 and the second pawl 6 are in direct contact with their parts of the key switch 8, as it is also from the 6 and 7 results.
  • the rotary latch 2 In this position of the locking both pawls are outside, that is, at the peripheral regions of the rotary latch 2, on. In this case, the rotary latch 2 now releases the locking pin, so that the corresponding door or the flap of the motor vehicle can be opened.
  • a further embodiment of such a lock unit 1 goes out Fig. 8 out. Shown is the "Vorrast" position of the locking mechanism.
  • the lock unit 1 which is installed in particular in a motor vehicle 12, acts together with a locking bolt 14 fastened on the body side.
  • the locking pin 14 is immersed in the closing movement of the motor vehicle door in an inlet mouth 17 of the lock plate 13 and is at least partially encompassed by the catch 2.
  • the insertion movement of the locking bolt 14 rotates the spring-biased rotary latch 2 counterclockwise.
  • the first pawl 5 is thereby motivated, for example, by means of a spring-biased blocking lever 15, also to turn counterclockwise, so that a secure contact with the peripheral surface of the rotary latch 2 and then a direct engagement before the main ratchet during the closing process is guaranteed.
  • the second pawl 6 is spring-biased so that it is preferably pivoted counterclockwise, this pivoting range is limited. Shown here is now the position Vorrast, in which the second pawl 6 cooperates with the pre-catch 4 of the catch 2. Now, for example, a Schlosszuzieh Bü could be used, the electric motor, the rotary latch 2 further pivots until the first pawl safely before the main rest comes to rest.
  • a common position detection means 7 for uniquely identifying the position of the first pawl 5 and the second pawl 6, so that information about the state of the lock unit 1 can be obtained.
