Description

Castle gate array

The invention relates to a lock logic arrangement for a motor vehicle lock assembly according to the preamble of claim 1 and a Kiaftfahr- ziegschlossanordnung as such according to the Oberhegriff of claim 1 S.

The term "JCraftfahrzeugschlossanordnung" here all types of door, hood or flap lock assemblies are summarized. The motor vehicle mechanical arrangement in question is equipped with a lock logic arrangement on the one hand and a locking mechanism on the other hand. While the lock logic arrangement serves to set different lock states such as "unlocked" and "locked", the lock mechanism ensures that the holding forces required for holding the respective motor vehicle door or the like are accommodated.

The known lock logic arrangement (DE 20 2013 105 314 U1), from which the invention is based, is assigned to a motor vehicle body assembly which, in the mounted state, is coupled at least to an outside door handle. The lock mechanism has a switching element configured as a central locking lever with which the lock states "unlocked" and "locked" can be set. In the lock state "unlocked", the lock mechanism can be opened by a mechanical actuation of the outside door handle, while in the lock state "locked" a mechanical actuation of the outside door handle is released or blocked.

The adjustment of the central locking lever in its respective switching positions is carried out by an actuator, which is coupled via a push-push mechanism with the central locking lever. The push-push mechanism has an input lever, an intermediate lever mounted on the input lever and spring-biased in a central position, and the switching element designed as a central locking lever. Although this push-pull mechanism, which consists of three levers, is mechanically robust, it is relatively expensive to produce. In another known lock logic arrangement (DE 20 2016 100 521 Ul) is a push-push mechanism application for the realization of a child safety fiinktion, with a door inside handle if necessary, is deactivated A manufacturing technical simplification of the above lock logic arrangement does not arise from this

The invention is based on the problem, the known Schlosslogikanordnung such design and further develop that the cost of their production is reduced.

The above problem is solved in a lock logic arrangement according to the preamble of claim 1 by the features of the characterizing part of claim 1. It is essential to realize that for the realization of a push-push function in which in the course of a push movement the switching element occupies a new switching position and in the course of a loading movement, the switching element maintains its switching position, a kind of ratchet function between input element and switching element must be provided. This means that the push movement of the input element causes the above switching of the switching element while the charging movement has as little as possible or only a slight effect on the switching element

According to the proposal, it has now been recognized that no additional intermediate lever is required for the above-mentioned ratchet function. Rather, the ratcheting function can be produced by the switching element itself, as long as a snap spring arrangement is associated with the switching element

Specifically, it is proposed that the detent spring arrangement fixes the switching element in the switching positions in a latching manner. The detent spring arrangement is tensioned by the input element in the course of a push movement of the input element and then latched over. In the course of a loading movement of the input member, however, the detent spring assembly is merely stretched by the input member, but not latched The detent spring arrangement ensures that the switching element assumes a mechanically stable equilibrium state in the switching positions. This means that a deflection of the switching element out of the respective switching position takes place against the spring force of the detent spring arrangement. After the above latching of the detent spring arrangement, the detent spring arrangement produces a mechanically stable equilibrium state for the respectively new switching element, so that the switching element, driven by the detent spring arrangement, falls after the latching in the new switching position

According to the proposal, it is thus so that the push movement causes a catching of the detent spring arrangement and thus a spring-driven adjustment of the Schaltele- management in the new switching position and that a loading movement only a deflection of the switching element from the respective switching position out, but not a Uberrasten causes, so that after completion of the loading movement, the switching element, in turn driven by the detent spring assembly, can fall back into its original switching position. It is striking that the push-push function can be implemented with the proposed solution consisting of only two levers and one detent spring arrangement. A kind of intermediate lever to realize the ratchet function is no longer necessary.

In the particularly preferred embodiment according to claim 2, the proposed lock log assembly for the realization of a Zentralverrie- gelungsfunktion, in individual for the realization of the lock states "unlocked" and "locked" is used. The high degree of mechanical robustness of the proposed lock logic arrangement which is achievable not least because of the low number of parts leads to the proposed lock logic arrangement being particularly suitable for the central locking function which is the most frequented in a motor vehicle

The further preferred embodiment according to claim 3 relates to the use of the detent spring arrangement for the implementation of a second part of the switching movement of the switching element, in which the input element has already come except driving engagement of the switching element is thereby the driving engagement between the input element and the switching element implement in a structurally particularly simple way. In the particularly preferred embodiment according to claim S, a push movement always causes a switching movement in one and the same direction of movement. In this case, the switching element is preferably designed to be endlessly rotatable. Different drive directions are therefore not required for the adjustment of the switching element, which further simplifies the structural design.

The proposed solution allows according to claims 9 to 12 that the actuator is designed unidirectional (claim 9). For the return of the input element, a return spring according to claim 10 is accordingly provided which acts against the drive direction of the input element.

An embodiment according to claims 9 and 10 can best be realized by a particularly preferred embodiment according to claim 11, wherein the drive of the input member via a flexible traction means, in particular a rope, a belt or a chain takes place. This can be implemented not only in a technically simple way but also cost-effectively.

In the particularly preferred embodiment according to claim 12, the loading movement of the input member is driven by the drive motor of the actuator, while the push movement is driven by the return spring assembly. This allows, for example, a comparatively weak design of the drive motor, since the movement in the drive direction of the input element does not necessarily have to be done at high speed. This is different in the return movement, which is here and preferably yes to the push movement, which must bring about the desired switching of the switching element as quickly as possible. The further preferred embodiments according to claims 13 and 14 relate to manufacturing technology easy to implement and especially compact design variants for a central locking clutch, which is controlled by the switching element. Of particular interest is the design according to claim 14, in which the coupling element is adjustable at least in a movement component in the direction of the axes of rotation of the clutch lever. An adjustment of the coupling element transverse to the axes of rotation of the clutch lever, which always requires space, is therefore not essential.

According to another teaching according to claim 15, which has independent significance, a motor vehicle safety device with a proposed Ben lock logic assembly and a barrier claimed, wherein the motor vehicle lock assembly is coupled in the mounted state with an outside door handle and possibly with a door inner handle. Reference may be made to all statements regarding the proposed lock logic arrangement.

In the following the invention will be explained in more detail with reference to a drawing showing only an exemplary embodiment. In the drawing shows

Fig. 2, the proposed lock logic arrangement according to FIG. 1 in a

Exploded

A) in the lock state "unlocked", b) in the lock state "unlocked" after completion of the loading movement of the input element and c) "locked" in the lock state, each in a Top view and

4 shows the central locking coupling of the lock logic arrangement according to FIG. 2 a) in the lock state "unlocked" and b) in the lock state "locked", in each case in a perspective illustration.

The proposed lock logic arrangement 1 is assigned to a motor vehicle lock arrangement 2. With regard to the broad interpretation of the term "motor vehicle lock arrangement", reference may be made to the introductory part of the description.

The motor vehicle lock arrangement 2 has, in addition to the lock logic arrangement 1, a blocking mechanism 3 which here and preferably has the usual closing elements lock latch 4 and pawl 5. The latch 4 can be brought into a closed position shown in FIG. 1, in which it is in holding engagement with a closing wedge 6 o. The like. Instead of the closing wedge 6 can also be a striker, a locking pin o. The like. Find application. The pawl 5 holds the latch 4 in its closed position. For opening the blocking mechanism 3, the pawl 5 can be adjusted to a raised position, not shown, in which it releases the latch 4, so that the associated motor vehicle door or the like can be opened.

In the assembled state, the KjBftfahrzeugschlossanordnung 2 is mechanically coupled to an outside door handle 7 and possibly with a door handle 8 This coupling is preferably via a Bowden cable, a linkage o. The like .. In the exemplary embodiment shown in FIG. 1 and insofar preferred the lock logic assembly are the first and the locking mechanism 3 in a unit summarized and received in particular in a housing 9. However, in principle it can also be provided that the lock logic arrangement 1 and the blocking mechanism 3 are arranged separately from one another and, in particular, are arranged in separate housings.

2 shows that the lock logic arrangement 1 has a lock mechanism 10 and an actuating drive 11, wherein the lock mechanism 10 can be brought into different lock states by means of the set drive 11, which are shown in FIGS. 3a, 3c and in FIGS. 4a, 4b are shown.

The locking mechanism 3 can be opened in the mounted state of the motor vehicle lock arrangement 2 as a function of the mechanical lock states by a mechanical, manual actuation of the outside door handle 7 and possibly the inside door handle 8. The mechanical, manual operation of the outside door handle 7 relates here to a movement of the outside door handle 7 performed by the operator, which is transmitted to the pawl 5 of the blocking mechanism 3 as a function of the lock state. The lock mechanism 10 is equipped with a push-push mechanism 12, by means of which the lock mechanism 10 can be adjusted to different lock states. The push-push mechanism 12 has an input element 13 which can be adjusted by means of the actuator 11 and which can be adjusted in a push movement 14 and an opposite loading movement 15. Here and preferably, the push movement 14 and the loading movement 15 are opposite, in terms of amount but identical to each other. The amount of movement in the present case always affects the path of movement.

The push-push mechanism 12 also has an adjustable switching element 16 which can be brought via switching movements 17 in at least two switching positions, preferably in at least three switching positions, here and preferably in four switching positions. In general, it is provided that in the course of a push movement 14, the switching element 16 from a switching position out (Fig. 3a) in a switching movement 17 assumes a new switching position (Fig. 3c). In the course of a loading movement 15, however, the switching element 16 maintains its switching position.

It is essential for the proposed solution that the push-push mechanism 12 is associated with a detent spring assembly 18 which sets the switching element 16 each detent. This is shown in Figs. 3a, 3b and 3c. In the course of a push movement of the input element 13, which results from the transition from FIG. 3 b to FIG. 3 c, the detent spring arrangement 18 is initially tensioned and then latched over. In the course of a loading movement 1 S of the input element 13, which results from the transition from FIG. 3 a to FIG. 3 b, the detent spring arrangement 18 is indeed tensioned but not latched. Interestingly, in the push movement 14 the fact that the detent spring assembly 18 is relaxed again after overrunning until the switching element 16 has assumed its new switching position. Thus, the detent spring assembly 18 can be used to cause a portion of the push movement 14, as will be explained.

The switching element 16 is preferably a central locking lever, the lock mechanism 10 "unlocking" in the lock state as a function of the switching position of the switching element 16 in that a mechanical, manual actuation of the outside door handle 7 opens the locking mechanism 3, or in the lock state "locked" by a mechanical, manual operation of the outside door handle 7 is freewheeling or blocked, Fig. 3a shows the lock state "unlocked" generating switching position, while Fig. 3c shows the lock state "locked" generating switching position. By the proposed equipment of the push-push mechanism 12 with a detent spring assembly 18, it may be readily provided that the Rastfe- deranordnung 18 causes after latching at least part of the switching movement of the switching element 16 in the new switching position. In a particularly preferred embodiment, it is correspondingly so that each push movement 14 causes only a first part of a switching movement of the switching element 16 in the direction of the new switching position and the locking of the detent spring assembly 18, whereby the detent spring assembly 18, the second part of the switching movement of the switching element In the second part of the switching movement of the switching element 16, the input element 13 is preferably already disengaged from the switching element 16.

In detail, it is here and preferably such that the input element 13 has at least one engagement part 19, here and preferably exactly one engagement part 19, and the switching element 16 has at least one counter-engagement part 20, here and preferably four counter-engagement parts 20. In the course of a push movement 14, an engagement part 19 of the input element 13 now engages with a counter-engagement part 20 of the switching element 16, whereby the switching element 16 is moved about the first part of the switching movement. Since this is connected to a latching of the detent spring arrangement 18, the detent spring arrangement 18 ensures the second part of the scarf movement 17, as mentioned above. In the course of the second part of the switching movement 17, here and preferably another counter-engagement part 20 comes into the movement area of the engagement part 19. This corresponds to the transition of Fig. 3b to Fig. 3c, in which the switching element 16 has reached its new switching position. A charging movement 15 of the input element 13, as results from the transition from Fig. 3a to 3b, has only a minor effect on the switching element 16, but does not affect the switching position of the switching element 16 In detail, the switching element 16 performs in the course the loading movement 15, driven by the input member 13, an evasive movement out of the movement range of the input member 13, without latching the detent spring assembly 18. This means that the switching element 16, driven by the detent spring arrangement 18, falls back into its switching position as soon as the engagement part 19 is pivoted past the counter-engagement part 20 of the switching element 16. Here and preferably, the input element 13 and / or the switching element 16 in each case about an axis of rotation 13 a, 16 a pivotally. The rotation axes 13a, 16a of input element 13 and switching element 16 are parallel to each other, but spaced from each other.

It should be noted that in the case of the illustrated preferred exemplary embodiment, the switching element 16 moves with each push movement 14 of the input element 13 in a switching movement 17 with one and the same direction of movement. Ultimately, the switching element 16 is formed here and preferably endlessly rotatable. This means that the switching element 16 with each switching movement 17 is to a certain extent further rotated by a switching position. This also means that several switching positions can be realized, which can each produce a different lock state.

Here and preferably, however, it is provided that the switching element 16 has at least two, here and preferably four, different switching positions that produce one and the same lock state. In the exemplary embodiment shown, the switching element 16 has two switching positions which produce the lock state "unlocked." This corresponds to the switching position shown in Fig. 3a and a switching position in which the switching element 16 is further rotated by 180 ° two switch positions "locked" producing the lock state. This corresponds to the switching position shown in Fig. 3c and a switching position in which the switching element 16 is further rotated by 180 °

In the exemplary embodiment shown, which is preferred so far, provision is finally made for the switching element 16, via its adjustment, to alternately assume the switching positions producing different lock states

With the above-mentioned, multiple, here double realization of a lock state by several, here two, switching positions, the amount of the switching movement can be reduced, since a full revolution of the switching element 16 divides the respectively provided number of switching positions.

The detent spring arrangement 18 is, as shown in FIG. 3, implemented in a particularly simple manner. The detent spring arrangement 18 has a latching surface 21, while the switching element 16 has a counter-latching surface 22 latching surface 21 and Counter-latching surface 22 are engaged with each other in such a way or can at least be brought into engagement with one another such that an adjustment of the switching element 16 between two switch positions is connected to a tensioning and unclamping of the detent spring arrangement 18. As described above, between the clamping and the relaxing of the detent spring arrangement 18, the locking of the detent spring arrangement 18 is provided. As also shown in Fig. 3, the detent spring assembly 18 is supported on the counter-latching surface 22 of the switching element 16 resiliently. For this purpose, the detent spring arrangement 18 has a detent spring 23, which is formed at least in sections, here and preferably completely, from a spring wire. Shown and so far preferred is the embodiment of the detent spring 23 in the manner of a leg spring.

Of particular importance for the proposed function of Rastfederan- order 18 is the shape of the counter-locking surface 22 such that the detent spring 23 which is resiliently supported on the counter-latching surface 22, engages upon reaching the respective switching position in the counter-latching surface 22. Accordingly, for generating the latching action the counter-latching surface 22 in cross-section transverse to the axis of rotation 16a of the switching element 16 polygonal, preferably star-shaped configured. In order to further enhance the locking action, the locking surface 21 is formed on the detent spring 23 complementary to the counter-latching surface 22. In the illustrated embodiment, this means that the detent spring 23 has a kink 23 a.

The drive technology coupling of the actuator 11 with the input member 13 is optimized in the illustrated embodiment of the push-push mechanism 12 out. It is preferably such that the actuator 11 is coupled to the input element 13 only unidirectional drive technology, so that the input member 13 is adjustable by means of the actuator 11 only in a single drive direction 24 of the input member 13. The return of the input element 13 is spring-driven by a Rückstellfederano- rdnung 25 is provided which acts against the drive direction 24 on the input member 13.

By the above, unidirectionally provided, drive-technical coupling of the actuator 11 with the input member 13 can be a flexible traction means 26 between actuator 11 and input member 13 switch. In detail is It is provided that the actuator 11 has a drive motor 27, wherein the drive-technical coupling between the drive motor 27 and the input member 13, a flexible traction means 26, here and preferably a rope, a belt or a chain has. In a particularly preferred embodiment, the input element 13, as shown in the drawing, designed as a pulley on which the flexible traction means 26 can be wound or from which the flexible traction means can be unwound

The loading movement 15 of the input member 13 is here and preferably driven by the drive motor 27 and directed in the drive direction 24 of the input member 13, while the push movement 14 here and preferably driven by the return spring assembly 25 and directed against the drive direction 24. In this way, the motor-driven loading movement 15, in which the restoring spring arrangement 15 is tensioned, can take place comparatively slowly, since no switching of the switching element 16 occurs with this loading movement 15, as explained above. For example, it would be conceivable that the loading movement 15 has already been made before the operator triggers a change in the lock state, for example via a radio remote control. However, it is also conceivable that the loading movement 15 will only be performed when the operator triggers the change of the lock state

For the realization of the lock states "unlocked" and "locked", the lock mechanism 10 has a central locking clutch 28, which shows a structurally particularly simple construction. The central locking clutch 28 has, as shown in FIG. 4, a first clutch lever 29, which in the mounted state is connected to the locking mechanism 3, in particular to the locking pawl 5, a second clutch lever 30, which in the mounted state with the Door outside handle 7 is connected, as well as in a coupling position (Fig. 4a) and in a Entkuppelstellung (Fig. 4b) adjustable coupling element 31. The two clutch levers 29, 30 are coupled to each other in dependence on the position of the coupling element 31 or decoupled from each other, wherein the coupling element 31 is adjustable by the switching element 16. For this purpose, the switching element 16, as shown in a synopsis of Figs. 3 and 4 - Goes to a guide slot 32, the coupling element 31 in response to the switching position of the switching element 16 in the coupling position (Fig. 4a) o- or in the Entkuppelstellung (Fig. 4b) deflects or releases This is the Coupling element 31 by means of a clutch spring 32, here and preferably in the Entkuppelstellung biased.

In the illustrated preferred embodiment, the axes of rotation 29a, 30a of the two clutch levers 29, 30 are aligned parallel to each other, more preferably coaxially. In this case, the coupling element 31 is at least in a movement component along the pivot axes 29a, 30a of the clutch lever 29, 30 adjustable. The coupling element 31 is, as shown in Fig. 4, preferably articulated on one of the clutch lever, here on the first clutch lever 29, pivotally. It has a guide surface 33 which engages with the guide slot 32 of the shift element 16. The axis of rotation 16a of the switching element 16 is parallel to and preferably spaced from the axes of rotation 29a, 30a of the two clutch levers 29, 30. The guide slot 32 provides a rotationally oriented relative to the axis of rotation 16a of the switching element 16 running surface for the guide surface 33 of the coupling element 31 ready. The fact that here and preferably two switching positions are provided in order to produce the lock state "unlocked", the switching element 16 is provided with two guide slots 32, the relation to the axis of rotation 16a of the switching element 16 offset by 180 ° to each other According to a further teaching, which has independent significance, a motor vehicle lock arrangement 2 with a lock logic arrangement 1 and a locking mechanism 3 is claimed, wherein the motor vehicle lock arrangement 2 in the assembled state is mechanically provided with an outside door handle 7 and optionally with a door inside handle 8 The lock logic arrangement 1 is a proposed lock logic arrangement, so that in this respect reference may be made to all the above explanations.
