Definitions
- the invention relates to a motor vehicle lock mechanism, in particular a motor vehicle door lock mechanism, with at least one rotary latch and a pre-latching pawl and a main latching pawl as at least two pawls, wherein both pawls are axially coaxial with one another and are rotatably mounted and the pre-latching pawl interacts with a pre-latching of the rotary latch in a pre-latching plane and the main latching pawl interacts with a main latch of the rotary latch in a main latching plane parallel to this and spaced apart.
- Locks on motor vehicle locks i.e. motor vehicle lock locking devices
- motor vehicle lock locking devices mainly perform a safety function and ensure that not only can a motor vehicle door equipped with the motor vehicle lock and consequently also the motor vehicle lock locking device be securely locked against a motor vehicle body.
- structural forces are also transmitted via the motor vehicle lock locking device in the event of a crash.
- DE 102010011 322 A1 uses a convex curvature that is located in an area of the rotary latch, and at least in one section that extends into contact with the locking bracket or a locking bolt.
- the rotary latch can be equipped with a sandwich-like structure.
- the convex curvature there is a rounded contact area on the locking bracket or locking bolt and an overall reduction in undesirable noise emissions, which could previously be attributed to a relative movement between the locking bracket or locking bolt and the rotary latch.
- a first pawl or main locking pawl is implemented and, in addition, a second pawl or pre-locking pawl.
- the first pawl or main locking pawl can be brought into engagement with a main notch on the rotary latch.
- the second pawl or pre-locking pawl on the other hand, can be brought into engagement with a pre-lock on the rotary latch.
- the pre-lock on the rotary latch is a bolt-like pin on the rotary latch.
- the design of the generic teaching according to WO 2008/061491 A1 is such that in the locked state, the rotary latch introduces a pivoting moment into the first pawl or main locking pawl.
- the first pawl is fixed using a blocking lever.
- the rotary latch pivots the first pawl or main locking pawl in the direction of the opening position. This means that the associated operating forces when opening are relatively low.
- the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that all safety requirements are met better than before and at the same time an embodiment with low opening forces and reduced noise emissions is observed.
- the invention proposes, starting from a generic motor vehicle lock mechanism, that the rotary latch is composed of a main latching rotary latch having the main latch and a pre-latching rotary latch having the pre-latching rotary latch, which are connected to one another in a sandwich-like stack.
- a pre-latching rotary latch having the preliminary latch is also provided, which, in contrast to the prior art, is not limited to a bolt-like pin. Rather, according to the invention, the pre-latching rotary latch having the preliminary latch has its own surface area, which largely corresponds to that of the main latching rotary latch. In this way, the main latching rotary latch and the preliminary latching rotary latch can be connected to one another in a sandwich-like stack.
- the main latching rotary latch and the pre-latching rotary latch are each plate-shaped or disc-shaped.
- the two plates or discs are connected to one another in a sandwich-like stack.
- the surface area between the main latching rotary latch and the pre-latching rotary latch largely coincides, particularly in the area of the inlet mouth, into which a locking bolt or striker typically enters and is caught during a locking process.
- the inlet mouth is usually limited by two arms, namely a stop arm and a load arm of the rotary latch.
- the locking bolt moves into the inlet mouth and, with its contact or stop on the stop arm of the rotary latch, ensures that the rotary latch moves into its closed position.
- the rotary latch first takes up its pre-locking position and then the main locking position.
- the load arm on the other hand, mainly absorbs the attacking tearing forces.
- both the main locking rotary latch and the pre-locking rotary latch are designed as metal stampings, for example.
- the metal stampings in question can be made from the same or different metals.
- the main latching rotary latch and the pre-latching rotary latch are made of materials of different hardness and/or are coated with different hardness.
- the main latching rotary latch is made of a material that is harder than the Pre-latching rotary latch is made of a harder material or is coated with a harder material. This increases the overall strength of the rotary latch, without it having to be particularly thick or without additional reinforcement measures having to be integrated.
- the coating and/or the material of the pre-latching rotary latch protrudes slightly from the coating and/or the material of the main latching rotary latch.
- the coating and/or the material of the pre-latching rotary latch protrudes a few tenths of a millimeter beyond the coating and/or the material of the main latching rotary latch.
- This has the advantage that contact with the pawl, for example, only occurs on the softer material, which further improves the acoustics. In this way, the noise behavior is positively influenced while at the same time meeting the safety requirements.
- the main latching rotary latch is equipped with a latching element that is pivotably mounted on it. This means that any opening and closing processes starting from the main catch are carried out with particularly low noise and with little operating force.
- the locking element can be at least partially secured and covered using the pre-locking rotary latch.
- additional guides ensure that there is no pre-locking snagging or that the main locking pawl can engage in a necessary free space between the locking element and a holder that supports the locking element.
- the guides in question can be implemented on the main locking rotary latch and/or the main locking pawl.
- the pre-latch rotary latch can be made of a softer material than the main latch rotary latch or can be covered with such a material, this also has a positive effect on the closing behavior and corresponding noise emissions. This is also achieved with the invention. without there being or having to be a locking element on the pre-locking rotary latch, which is also conceivable at this point and pivotably mounted on it.
- the main latching rotary latch and the pre-latching rotary latch can be connected to one another in a variety of ways in a sandwich-like stack. For example, it is conceivable to use typical mechanical connections such as a coupling by riveting, screwing, stamping, etc. Of course, the measures mentioned can also be combined with one another. In general, the main latching rotary latch and the pre-latching rotary latch are connected to one another at least at certain points.
- the pre-latching pawl and the main latching pawl are rotationally coupled to one another in such a way that the pre-latching pawl takes the main latching pawl with it after a defined free travel, for example when the locking mechanism is opened.
- the associated vehicle door can be opened without any problem.
- a motor vehicle lock and in particular a motor vehicle door lock is provided and delivered which both meets all safety-specific requirements and can be opened with low actuation forces.
- a particularly quiet operation is observed.
- This can ultimately be traced back to the combination of the sandwich-like stacking structure of the rotary latch from the main latching rotary latch and the pre-latching rotary latch on the one hand in conjunction with the additional latching element on the main latching rotary latch on the other. Due to the sandwich-like By stacking the main latching rotary latch and the pre-latching rotary latch and mechanically connecting them to each other, virtually any strength for the rotary latch can be achieved and implemented without the need for additional and complex reinforcement measures.
- the opening process of the locking mechanism is particularly successful with little force because the locking element allows and defines a rolling movement between the locking mechanism parts moving relative to one another, whereas in the previous state of the art, predominantly grinding movements are observed at this point.
- both the main latching rotary latch and the pre-latching rotary latch, as well as the main latching pawl and the pre-latching pawl, are typically metal stamped parts that can be manufactured inexpensively and with the desired properties without any problems.
- the union between the main latching rotary latch and the pre-latching rotary latch only requires an established mechanical connection process, such as the insertion of rivets, screws, stampings or, in principle, welding the two rotary latches together.
- a point connection for example at three points, is sufficient, which further reduces the manufacturing effort.
- Fig. 1 shows the motor vehicle lock mechanism according to the invention in the form of a motor vehicle door lock mechanism in plan view and partially in perspective in the main locking position and Fig. 2 shows the motor vehicle lock mechanism according to Fig. 1 schematically in the pre-locking position,
- Fig. 3 a detail from Figures 1 and 2 and
- Fig. 4 shows a further detail in the area of the intended locking element.
- the figures show a motor vehicle lock and locking mechanism and in particular a motor vehicle door lock and locking mechanism.
- This is made up of at least one rotary latch 1, 2 and a pre-latching pawl 3 and a main latch 4 as at least two pawls 3, 4.
- the rotary latch 1, 2 in conjunction with the two pawls 3, 4 can generally be rotatably mounted in a metal lock case 5 indicated in Fig. 1 and represents the essential component of a motor vehicle lock and in particular a motor vehicle door lock, which is otherwise not shown in more detail.
- the term motor vehicle lock or motor vehicle door lock is to be interpreted broadly in a very general and inventive manner and ultimately includes any locking device with the aid of which flaps, hoods, doors, etc. are locked in or on a motor vehicle.
- both pawls 3, 4 are mounted on the same axis as one another.
- both pawls 3, 4 have aligned holes for the engagement of a bearing pin 6.
- the bearing pin 6, as well as another bearing pin 7 (not shown in detail), is anchored in a bearing opening for the rotary latch 1, 2 in the lock case 5.
- both pawls 3, 4 are each designed in a C-shape in plan view, with the bearing pin 6 being arranged in the area of the connection between both C-legs.
- One C-leg of the respective pawl 3, 4 may typically be used to pivot the pawl 3, 4.
- the other C- In contrast, the leg interacts with the rotary latch 1, 2, as will be explained in more detail below.
- the C-shape of the two pawls 3, 4 described above as an example primarily stems from or is due to the fact that the pawls 3, 4 in question are equipped with a predominantly invisible metal core and a plastic casing.
- the plastic casing determines the C-shape described.
- the metal core can be designed differently.
- the C-shape of the plastic casing makes it possible to actuate individual sensors or switches (not shown) in a particularly elegant and advantageous way. These sensors or switches can be used to query the movement of the pawls 3, 4 and thus draw conclusions about the functional state of the locking mechanism.
- the C-leg furthest from the rotary latch can interact with the sensors or switches.
- the overall design is such that the pre-latching pawl 3 interacts with a pre-latching 1a of the rotary latch 1, 2, specifically in a pre-latching plane spanned by the pre-latching pawl 3.
- the main latching pawl 4 interacts with a main latch 2a of the rotary latch 1, 2 in a main latching plane that is parallel to and spaced from the aforementioned pre-latching plane.
- This main latching plane is therefore primarily spanned and described by the main latching pawl 4.
- the main latch 2a is formed on a latching element 10 (see Figures 1 and 3).
- the rotary latch 1, 2 is now composed of a main latching rotary latch 2 having the main latch 2a on the one hand and an additional pre-latching rotary latch 1 having the pre-latching 1a on the other hand.
- Both rotary latches 1, 2 are connected to one another in a sandwich-like stack, as can be seen in particular from the perspective representations in Figures 1 and 2.
- the overall design is such that, according to the exemplary embodiment, both the main locking rotary latch 2 and the pre-locking rotary latch 1 are each designed in the form of a plate or disc with a predominantly identical surface. This predominantly identical surface is observed in the exemplary embodiment in particular in the area of an inlet mouth 8 of the rotary latch 1, 2 and also in the area of the bearing opening 7, which is provided for receiving the bearing bolt that rotatably supports the rotary latch 1, 2.
- both the main latching rotary latch 2 and the pre-latching rotary latch 1 are metal stamped parts. These can be made of the same or different metals. It is also conceivable that the main latching rotary latch 2, like the pre-latching rotary latch 1, have a casing not shown in the exemplary embodiment. Of course, the casing in question is just as unnecessary. In one exemplary embodiment of the invention, the main latching rotary latch 2 and the pre-latching rotary latch 1 are made of materials of different hardness and/or have casings of different hardness. For example, it is conceivable that the main latching rotary latch 2 is made of a harder material than the pre-latching rotary latch 1 or is casings of a harder material.
- the casing and/or the material of the pre-locking rotary latch 1 protrudes slightly from the casing and/or the material of the main locking rotary latch 2.
- the casing and/or the material of the pre-locking rotary latch 2 protrudes a few tenths of a millimeter beyond the casing and/or the material of the main locking rotary latch 1. This has the advantage that contact with the pawl 3, 4, for example, only occurs on the softer material, which further improves the acoustics.
- connection points 9 are implemented between the pre-locking rotary latch 1 and the main locking rotary latch 2.
- the connection points 9 are implemented and implemented using rivet connections. In principle, screw connections, stampings or even welding can also be used here in order to couple the two rotary latches 1, 2 together in a rotationally fixed manner.
- the connection points 9 form a triangle for this purpose.
- a load arm of the rotary latch 1, 2 is equipped with two connection points 9 in order to provide the required strength (keyword: tearing forces).
- the two locking pawls 3, 4 are also plate-shaped or disc-shaped according to the embodiment. As in the case of the two rotary latches 1, 2, in this case too they can be metal stampings. The use of the same or different metals is conceivable. In contrast to the two rotary latches 1, 2, the locking pawls 3, 4 are not coupled to one another in a rotationally fixed manner.
- the pre-latching pawl 3 and the main latching pawl 4 are rotationally coupled to one another in such a way that the pre-latching pawl 3 takes the main latching pawl 4 with it during an opening process and after a defined free travel.
- a free travel is typically required when the main latching rotary latch 2 opens faster than the pre-latching rotary latch 1. Either way, the free travel in question between the two pawls 3, 4 prevents any pre-latching snagging.
- the main rotary latch 2 is equipped with the locking element 10 pivotably mounted on it.
- the locking element 10 is accommodated in a receptacle 11 in the main rotary latch 2.
- the locking element 10 overall, this ensures that when the locking mechanism is opened, there is a rolling process between the main latch 4 on the one hand and the main rotary latch 2 on the other. This leads to a particularly low-force opening process, which is also associated with reduced noise emissions.
- the guides 12 as a whole ensure that the main locking pawl 4 can only engage during a closing process of the locking mechanism when the rotary latch 1, 2 or the main locking rotary latch 2 with the locking element 10 mounted therein has safely passed the projection on the main locking pawl 4 which interacts with the main catch 2a on the main locking rotary latch 2.
- Fig. 4 shows that the locking element 10 is equipped with a nose 10a which engages in an arcuate region 11a of the receptacle 11.
- the nose 10a on the one hand and the arcuate region 11a of the receptacle 11 on the other hand together define a rotary joint 10a, 11a which allows rotary movements of the locking element 10 about the axis defined thereby, as indicated by a double arrow in Fig. 4.
- This opening movement corresponds to the fact that the pre-locking pawl 3 and then the main locking pawl 4 are pivoted about their common axis under definition by the bearing bolt 6 in the clockwise direction indicated in Fig.
- the locking element 10 can roll on the edge in an anti-clockwise direction about its pivot point defined by the joint 10a, 11a until the two locking pawls 3, 4 ultimately release the rotary latch 1, 2, which then in turn pivots clockwise about the axis of rotation defined by the receiving opening 7 and releases a locking bolt previously caught in the inlet mouth 8 and not shown.
- An associated motor vehicle door, flap or the like can be opened as a result.
- the pre-locking rotary latch 1 is designed to at least partially secure and cover the locking element 10. This means that, based on the exemplary embodiment, it can be seen that the locking element 10 is ultimately arranged between the receptacle 11 in the main locking rotary latch 2 on the one hand and the pre-locking rotary latch 1, which at least largely covers the receptacle 11, on the other hand.
- the locking element 10 is received in a sandwich-like manner between the receptacle 11 or a base of the receptacle 11 on the one hand and the cover on the part of the pre-locking rotary latch 1 on the other hand and is secured against any axial movements.
