Definitions
- the invention relates to a motor vehicle lock having a locking mechanism with a rotary latch and at least one pawl, the rotary latch being lockable in at least one locking position by means of the pawl, an actuating element pivotably received in a bearing point, the bearing point having arms for holding the actuating element in the bearing point, and the lever arms of the actuating element overlapping the bearing point after being inserted into the bearing point.
- Levers are often used in motor vehicle locks to implement the various functions of the motor vehicle lock.
- the motor vehicle lock In addition to the locking mechanism, the motor vehicle lock then has, for example, a lever mechanism that enables locking, child safety, anti-theft protection, closing the lock, opening the side door and/or electrically unlocking the lock, to name just a few examples of some of the functions in a motor vehicle lock.
- the lever mechanisms are operated by means of a rod, a Bowden cable and/or, for example, by means of an electric motor with a downstream gear.
- the actuating elements or levers are mounted either in a lock case or in the lock housing or on a lever itself.
- DE 10 2008 039 240 A1 discloses a locking device having at least one locking mechanism with a rotary latch and a pivotable first pawl, wherein a release lever is moved in such a way that that the release lever interacts with a driving pin of the first pawl during its movement and forms a lateral pawl spring of a system between the driving pin and the release lever during the interaction.
- the pawl is considered as an actuating element in the motor vehicle lock
- the pawl is mounted on a metal bearing mandrel, whereby the bearing mandrel is fastened in the lock case by forming and preferably by riveting.
- this document discloses a fastening mechanism in which a pivoting component, here a mass inertia element, is received on a plastic mandrel by means of a bayonet-like closure.
- a pivoting component here a mass inertia element
- the plastic mandrel with its arms is guided through recesses in the mass inertia element and the mass inertia element is then twisted, whereby the twisting of the mass inertia element in relation to the plastic mandrel is designed in such a way that the mass inertia element can move freely without the arms coming into line with the recesses, so that the mass inertia element can function and be held securely.
- the plastic mandrel serves as a bearing point for the mass inertia element and forms a secure holding of the mass inertia element after the mass inertia element has been inserted, whereby the arms of the plastic mandrel overlap the mass inertia element.
- the receptacles known from the prior art for supporting an actuating element in the motor vehicle lock have generally proven themselves. However, there is always an effort to create bearing points for actuating elements in motor vehicle locks using the smallest possible means, for example to save on components, reduce the required installation space or reduce the weight of the motor vehicle lock. In any case, however, it must be possible to ensure that the functionality is operated safely, since motor vehicle locks are safety-relevant components.
- the invention is aimed at improving the motor vehicle lock.
- the object of the invention is to provide an improved motor vehicle lock.
- the object of the invention is to provide a bearing point for an actuating element which uses the smallest possible number of components, is space-saving and has the lowest possible weight.
- a structurally simple, inexpensive way of implementing the bearing point should be made possible.
- the object is achieved according to the invention by the features of independent patent claim 1.
- Advantageous embodiments of the invention are specified in the subclaims. It is pointed out that the embodiments described below are not restrictive, rather any variation of the features described in the description, the subclaims and the drawings is possible.
- a motor vehicle lock comprising a locking mechanism with a rotary latch and at least one pawl, wherein the rotary latch can be locked in at least one locking position by means of the pawl, a pivotable in an actuating element received in a bearing point, the bearing point having arms for holding the actuating element in the bearing point, and the holding arms of the actuating element overlap the bearing point after insertion into the bearing point, and the lever arms are deformable.
- the deformation can ensure secure holding, and on the other hand, the deformation of the actuating element itself can enable a bearing point, i.e. pivotable mounting of the actuating element.
- the deformation can provide a connection between the bearing element and the actuating element, a pivot bearing that comes about solely through interaction between the bearing point and the actuating element. It is thus possible to provide a pivotable mounting of an actuating element in the motor vehicle lock with the least possible means, i.e. with the smallest possible number of components.
- the forming itself replaces the alternative methods for connecting or creating a bearing point.
- the bearing point itself is provided by the interaction of the actuating element and the bearing point.
- Locking mechanisms consisting of a rotary latch and at least one pawl are installed in a lock for a motor vehicle, which is also called a locking system.
- the locking mechanism in the lock works together with a lock holder, which is either attached to the body of the motor vehicle or to the door. flap, sliding door, etc.
- the relative movement between the lock holder and the rotary latch causes the rotary latch to pivot and at the same time the pawl to engage with the rotary latch.
- There are locking mechanisms with a pre-latch and a main latch which are widely known from the state of the art.
- a pre-latch and/or a main latch there are one- or two-stage locking mechanisms, which then have a pre-latch and/or a main latch.
- the pawl is preferably brought into engagement with the rotary latch using spring tension.
- a release lever is used to unlock, i.e. to release the pawl from the rotary latch.
- the pawl is acted upon by the release lever in such a way that the pawl is disengaged from the rotary latch and the rotary latch can move from the latching position to an opening position.
- the rotary latch is usually moved by means of a spring element and/or due to a tensile load that results from the lock holder in combination with the door seal.
- An actuating lever chain with at least one actuating lever is used to actuate the release lever.
- the actuating lever can be an internal actuating lever or an external actuating lever, for example, to name examples of areas of application for an actuating lever.
- the actuating lever is used to move the release lever and unlock the locking mechanism. It can be advantageous if two, three or more holding arms overlap the actuating lever or the actuating element.
- the number of holding arms can be used to adjust the pivoting movement of the actuating element or the actuating lever, and the number of Holding arms can influence the freedom of play of the actuating element in the bearing point.
- the holding arms therefore serve on the one hand to adjust the swivel angle and on the other hand to enable the bearing for the actuating lever to be stabilized.
- the number of holding arms can be selected or used accordingly.
- the bearing point and the actuating element are made of a metallic sheet, this again results in an advantageous design variant.
- Providing the bearing point and the actuating element from metal makes it possible on the one hand to use inexpensive components and on the other hand to enable stable bearing for the transmission of larger forces. Larger forces are required, for example, where a motor vehicle lock has to be closed. Large forces can also be required when setting up a door element that is frozen over, for example.
- the metallic components of the articulated connection of the metal parts can be used advantageously here.
- the bearing point is formed from an opening with an identical diameter.
- the bearing point is provided with an opening into which the actuating element is inserted. After the holding arms have been reshaped, the actuating element is connected to the bearing point. If an essentially circular opening is punched or, for example, drilled into the bearing point, this results in cost-effective and simple production.
- the actuating element can be easily pivoted using an opening with a uniform diameter.
- the bearing point has at least one deformation, in particular a bevel or an impression. If a deformation is introduced into the bearing point itself, the bearing point can take on an additional function.
- the bearing point serves, as the name suggests, to receive and store the actuating element. If, for example, a bevel is formed into the bearing point, the bearing point can also serve as a stop means in the interaction between the actuating element and the bearing point.
- the bevel can then interact with, for example, the actuating element and/or a holding arm and thus represent a swivel limit for the actuating lever.
- the actuating lever can then be moved against the bevel when swiveling, so that a separate stop for the actuating lever can be dispensed with.
- an impression is additionally or alternatively formed into the bearing point.
- An impression in the bearing point can also be easily formed into the bearing point using a forming stamp, for example, during the production of the bearing point. The impression then protrudes on one side beyond the bearing point. and can then serve as a stop for the actuating lever or as a stop for a holding arm, depending on the arrangement of the indentation.
- the separation of the bearing point in the area of the opening can advantageously work together with a bevel on the circumference of the opening, so that on the one hand the bevel and on the other hand the separation point can serve as a stop limit for the movement of the actuating element.
- This advantageous design variant makes it possible to provide a bearing point for the limited mobility of the actuating element without the need for additional parts to limit the swiveling.
- bevels, impressions and separation points can advantageously work together to enable the actuating element to be held securely and/or limited. If the bearing point has a tab, the tab extends into the opening of the bearing point at least in part, so that the position of the actuating element is secured. can be provided, then again an advantageous embodiment of the invention can be achieved.
- An extension can serve as the tab, which extends from a border of the opening on the tab towards the center of the opening.
- the opening is thus limited.
- the tab can also be formed into the tab during production of the opening and serves as a support for the actuating element.
- the tab has a symmetrical design and extends beyond a center of the opening.
- the tab can thus be assigned a dual function, especially if the tab not only serves to secure the position of the actuating element, but also interacts with the actuating element in such a way that the tab represents a pivot limit for the actuating element.
- the modifications mentioned at the bearing point can be introduced together in the bearing point and/or the actuating element, so that the corresponding functionalities can be achieved with the bearing point.
- Different pivot angles can be set by arranging the stops at a corresponding distance, and it can be possible to hold the actuating element securely in the bearing point, so that a a force can be transmitted across the bearing point with as little play as possible.
- a variant of the invention can also be achieved by designing the bearing point itself as part of a pivotably mounted lever.
- the bearing point itself can represent a lever and be pivotally mounted. This makes it possible to either exceed a large lever travel or to be able to provide a complex mechanism in the motor vehicle lock.
- a large movement is necessary, for example, if the door element is to be raised, or if the locking mechanism is to be closed from a pre-locking position of the locking mechanism to a main locking position of the locking mechanism by means of the actuating element according to the invention.
- the bearing point has a greater material thickness than the actuating element.
- the material differences can be used to set a clearance between the bearing point and the actuating element, so that precise movements can also be achieved using the bearing point in the lock.
- Figure 1 an exemplary representation of the invention of an axle-less joint in a three-dimensional representation, wherein the bearing point is formed from a pivotably mounted lever
- Figure 2 an alternative embodiment of the axle-less joint from an opposite view in relation to Figure 1
- Figure 3 a first step for joining the axle-less joint or before joining the bearing point to the actuating element
- Figure 4 a joined joint as a section through the bearing point
- Figure 5 also a view of the bearing point in a section with a view of the formed actuating element.
- Figure 1 shows a three-dimensional view of an axle-less joint 1 as part of a motor vehicle lock 2.
- the axisless joint 1 comprises an actuating lever 3 and a bearing point 4.
- the bearing point 4 is designed as part of a pivotably mounted lever 6.
- the lever 6 is pivotable around the axis 7 is pivotally mounted in the motor vehicle lock 2.
- the lever 6 and thus the bearing point 4 can therefore also be pivoted around the axis 7 in the direction of the arrow P2.
- the bearing point 4 comprises an opening 8, the opening 8 being enclosed by the bearing point 4.
- a parting line 9 is formed in the bearing point 4, the parting line 9 in this embodiment forming part of a bevel 10.
- a tab 11 is also formed in the bevel 10, which serves to stabilize the actuating lever 3 or the actuating element 3.
- the actuating lever 3 is fastened to the bearing point 4, the actuating lever 3 being positively connected to the bearing point 4 by means of lever arms.
- the actuating lever 3 is consequently received so as to be pivotable around the axis 5 and is held in the opening 8 by means of the holding arms 12, 13.
- the movement of the actuating element 3 is limited on the one hand by the parting line 9 and the stop surface 14 formed on the parting line 9 and the stop surface 15 on the bevel 10.
- the actuating lever 3 is therefore accommodated in the bearing point 4 so that it can be moved back and forth in the direction of the arrow P, starting from the stop surface 15 to the stop surface 14.
- the position of the actuating lever 3 is secured by the interaction of the circular end 16 of the actuating lever 3 in interaction with the holding arms 12, 13 and the position securing by the tab 11.
- the tab 11 extends over the middle of the axis 5, so that a secure mounting of the actuating lever 3 in the bearing point 4 is possible.
- the tab 11 is in this Embodiment symmetrical in relation to the central axis M of the tab 11.
- the pivot angle about the axis 5 of the actuating element 3 is limited by the stop surfaces 14, 15, whereby it is also conceivable that the retaining arms 12, 13 can serve as stops for the actuating lever 3 in conjunction with the bevel 10 and the parting line 9.
- the actuating lever 3 can serve, for example, as a closing lever for a locking mechanism.
- a part of a rotary latch (not shown) could engage in the bevel 17 and move the rotary latch from a pre-locking position into a main locking position.
- the lever 6 would be driven, for example, by means of a motor and/or a Bowden cable and pivoted about the axis 7 so that a closing force could be exerted on the rotary latch.
- the actuating lever 3 can be pivoted around the axisless joint 1 in the direction of the arrow P during the closing process.
- Figure 2 shows an alternative embodiment of an actuating element 18 in a three-dimensional representation and in a rear view of the actuating lever 18 in relation to Figure 1.
- the actuating lever 18 is also mounted in a pivotable lever 19, whereby the lever 19 can be pivoted around the axis 20.
- the bearing point 21 is provided with impressions 22, 23.
- the impressions 22, 23 are divided into different directions in the bearing point 21. If the impression 22 forms a raised area in the bearing point 21, the impression 23 is introduced as a depression in the bearing point 21.
- the impressions or deformations 22, 23 are thus formed in different directions in relation to the bearing point.
- two holding arms 24, 25 can be seen, which secure the actuating lever 18 in the bearing point 21.
- the depression 23 can, for example, interact with the holding arm 25, so that stops are present for the actuating lever 18.
- the arrangement of the holding arms 24, 25 and the orientation of the extensions 26 of the actuating lever 18, as well as the arrangement of the extension 26 in relation to the circular end 27 of the actuating lever 18, the pivot angle ⁇ of the actuating lever 18 can be adjustable.
- combinations of the features shown can also be provided so that different functions can be implemented with the axisless joint 1.
- the actuating lever 3, 18 is identical, whereas the bearing points 4, 21 form different receptacles for the actuating lever 3, 18.
- Figure 3 shows the arrangement of a lever 28 with a further embodiment of a bearing point 29 before assembly with an actuating lever 30.
- the holding arms 31, 32 are shown in an undeformed state.
- a bevel 33 is formed in the bearing point 29, which extends circumferentially around the opening 34 in some areas.
- Figure 3 shows an assembly aid, the supports 36, 37 for deforming the holding arms 31, 32.
- Figure 3 shows the state of the axis-free joint 38 before the actuating lever is joined to the bearing point 29 or the lever 28.
- Figure 4 shows the joined state of the actuating lever 30 and bearing point 29.
- the holding arms were formed using a stamp with a force F, for example, with the folding supports 36, 37 serving as counter supports.
- the supports 36, 37 are higher in the assembly aid 35 than the material thickness D l of the bearing point 29, so that there is a clearance S between the arms 31, 32 and the bearing point 29.
- Figure 5 shows the joining of the actuating lever 30 to the bearing point 29 using an alternative assembly aid 38.
- the assembly aid 38 does not have the supports 36, 37, so that when the holding arms 31, 32 are reshaped, the holding arms 31, 32 can rest on the bearing point 29 without play.
- the bearing point 29 has a greater material thickness D l than the actuating lever 30.
- the material thickness D B of the actuating lever 30 is less than the material thickness D L of the bearing point 29.
