Definitions

  • the present invention relates to a lock, in particular a motor vehicle lock with a lock housing, a lock case, a locking mechanism and an actuating device, wherein at least one component of the actuating device extends through an opening in the lock housing and this opening is formed with at least one reinforcing insert.
  • a motor vehicle lock serves to close motor vehicle doors, flaps and the like.
  • a motor vehicle lock comprises a locking mechanism with a catch and a pawl for locking.
  • the catch and the pawl are arranged so that they can receive and lock a body-mounted lock holder in the locked position.
  • the pawl has the task of locking the catch in this position.
  • Rotary latch and pawl are usually rotatably mounted on a basically metal lock case.
  • the lock case often performs other functions and can serve, for example, the attachment of the lock in a vehicle door or vehicle door.
  • other components or components may be attached to the lock case such as a rotatably mounted blocking lever, which is able to block the pawl in its locked position.
  • a reinforcing plate also basically made of metal, which serves to supplement the rotatable attachment of the catch and / or pawl.
  • Rotary latch and pawl are usually located between the lock case and the amplifier plate. Since the reinforcing plate basically only serves the improved attachment of the rotary latch and / or pawl, its base is regularly small compared to the base of the lock box.
  • a motor vehicle lock basically comprises a lock housing for covering one or more components of the motor vehicle lock.
  • the lock housing is often closed with a lock cover to further improve the desired protection of components.
  • the lock housing and the lock cover are preferably made of plastic for weight reasons.
  • An actuating device of such a motor vehicle lock is used to open the locking mechanism.
  • Such an actuating device may comprise a Bowden cable.
  • the Bowden cable soul can be passed through an opening in the lock housing, as the document WO 2009/049588 A2 can be seen.
  • a locking mechanism of a motor vehicle can be exposed to increased forces, in particular in the event of a motor vehicle side impact, for example when an outer door panel is pressed against the housing and causes massive deformation here. In the extreme case, this can lead to a blockage of the locking mechanism, so that an associated motor vehicle door can only be opened with great effort. Therefore, it has been proposed to provide reinforcing elements in the motor vehicle lock to improve the crash safety, z. B, in the form of reinforcing plates connected to the housing. In order to further increase operational safety even in the event of a crash, according to the WO 2009/049588 A2 taught to provide the aforementioned opening in the lock housing additionally with a reinforcing insert and that by a suitable extension of the reinforcing plate.
  • the publication FR 2 778 198 a motor vehicle lock with a housing, a lock case, a locking mechanism and an actuating device which extends through an opening in the lock housing therethrough.
  • the lock also includes a mounting rail which is connected to the lock case.
  • the publication WO 2008/104073 A1 discloses another motor vehicle lock having a housing, a lock case, a ratchet and an actuator extending through an opening of the lock.
  • a motor vehicle lock comprises the features of claim 1.
  • Advantageous embodiments emerge from the subclaims.
  • a motor vehicle lock is provided with a lock housing, a lock case, a locking mechanism and an actuating device, wherein at least one component of the actuating device, in particular a core of a Bowden cable extends through an opening in the lock housing.
  • This opening is provided with a reinforcing insert to ensure good reliability.
  • the reinforcement insert is part of the lock case.
  • the lock case according to the invention comprises two side walls, which form a right angle with the base of the lock case.
  • the side walls serve u. a. the protection of the locking mechanism attached to the base and, as a rule, the attachment of the lock.
  • the side walls extend to the height of the reinforcing insert.
  • the reinforcing insert is located between two end portions of the side walls. The side walls thus protect the reinforcing insert from undesired external mechanical effects such as impact loads. The operational safety is further improved.
  • the base of the plate or sheet, from which the lock case is machined, is basically relatively large. Against this background, it has proven to be advantageous to form the reinforcement insert from the lock case, so as to minimize a waste during manufacture or even completely avoided. Reinforcement insert and lock case are thus integrally connected.
  • the plate or sheet In order to work out this lock case from the base of the plate or the sheet, the plate or sheet is first suitably punched, drilled and / or milled. Subsequently, the punched plate or sheet is suitably bent to provide the lock case with the reinforcing insert. The waste resulting from the punching increases at most slightly by the provision of the reinforcing insert.
  • the reinforcing insert is preferably connected via a web to the base of the lock case. Such a connection between base and reinforcement insert has proven to be sufficiently stable. The reinforcing insert together with the bridge then contributes only slightly to the overall weight of the lock case.
  • the reinforcing insert is preferably fork-shaped or U-shaped to hang a Bowden cable comfortably.
  • the lock case including the reinforcement insert is basically made of metal to provide a mechanically stable base for the lock.
  • the lock housing is basically made of plastic to protect against pollution and the like with low weight.
  • the reinforcing insert is basically in the lock housing or within a double wall of the lock housing and is in particular connected to the lock housing by a snap connection. Externally, the lock resembles a conventional lock and can therefore be handled in the same way as conventional locks.
  • the strength of the lock case is greater than the thickness of a reinforcing plate of the motor vehicle lock.
  • the forces occurring during operation can be so useful mainly absorbed by the lock case.
  • the opening is advantageously particularly well reinforced and thus achieved a particularly high reliability.
  • the lock case is therefore preferably made of a 1.5 mm to 3 mm thick, in particular made of steel plate.
  • the reinforcing plate is therefore preferably made of a 0.5 mm to 2 mm thick, in particular made of steel plate.
  • the thickness of the lock case is then 1.5 mm to 3 mm, so for example 2 mm and the thickness of the reinforcing plate 0.5 mm to 2 mm, for example, 1.5 mm.
  • the reinforcing plate is in particular U-shaped and therefore does not have the from WO 2009/049588 A2 known extension, which serves to reinforce the opening of the lock housing.
  • FIG. 1 schematically illustrates a motor vehicle 14 with a door 15 having a motor vehicle lock 1.
  • a motor vehicle lock 1 can be actuated via a door handle 16 on the door 15, wherein an actuation action is transmitted to the locking mechanism 3 via an actuating device 6.
  • the actuating device 6 can basically be designed as a lever.
  • a Bowden cable 7 is shown.
  • the actuating device 6 extends into an interior 19 of the indicated lock housing 2.
  • the locking mechanism 3 is arranged, which has a rotary latch 4 and a pawl 5.
  • the catch 4 receives a body-side fastened lock holder 17 and is blocked by the locking pawl 5 by latching movement.
  • the Bowden cable 7 With the help of the Bowden cable 7, an opening movement of the door handle 16 can be transmitted to the pawl 5, that the pawl is pivoted out of the detent position shown.
  • the Fig. 2 shows a perspective view of an embodiment of a motor vehicle lock 1, in which case the encapsulated lock housing 2 can be seen.
  • an indicated opening 8 is provided, in which a Bowden cable 7 is guided or fixed via a bearing 32.
  • the opening 8 is inserted in a part of the lock housing 2 made of plastic.
  • the bearing 32 is inserted into the U- or omega-shaped opening 8, wherein there provided a reinforcing insert 9 (see, in particular FIG. 6 ) ensures the fixation of the bearing 32 even at high forces.
  • the reinforcing insert 9 is in the FIG. 2 not shown for reasons of clarity.
  • the ua in the FIG. 6 shown reinforcing insert 9 is about a in the FIG.
  • the Fig. 3 shows in perspective from another viewing direction fragmentary the Bowden cable 7 of the actuator, which is passed through the aforementioned opening of the lock housing 2, which passes through two walls or double wall 12 of the lock housing 2 and a double wall 12 therethrough.
  • the Bowden cable soul is moved in the direction of extension back and forth and acted upon by a corresponding force.
  • the reinforcing insert 9 is provided in the region of the opening with the adjacent wall regions 12, which essentially forms a same opening or receptacle for the Bowden cable 7.
  • the reinforcing insert 9 is located between the two walls 12 of the lock housing 2.
  • the reinforcing insert 9 is held by the two walls 12 preferably in latched form.
  • the reinforcing insert 9 extends downward in the direction of, for example, in FIG FIG. 5 shown web 10 and is integrally connected thereto.
  • FIG. 4 A preferred embodiment of a 1, 5 mm thick, preferably made of steel or another metal, U-shaped reinforcing plate 18 is shown with legs 28. Laterally projecting pins 20 serve to hook into a side wall 11 of a lock case 33, so as to avoid a lateral projection of the reinforcing plate.
  • a bore 22 in a leg 28 of the U-shape serves to receive the axis of rotation of the rotary latch. The bore preferably has a relatively large diameter, since the diameter of the rotary latch axis is usually relatively large.
  • Another bore 24 in the other leg 28 of the U-shape serves to receive the axis of rotation of the pawl.
  • the bore 24 preferably has a comparatively small diameter, since the diameter of the pawl axis is usually relatively small.
  • a lock case 33 is shown having a base 27 with the side wall 11.
  • the bore 23 in the base 27 has a relatively large diameter and serves for the rotatable mounting of the rotary latch axis.
  • a bore 30 in a further side wall 31 of the lock case 13 can serve for fastening the motor vehicle lock to a door or flap or for other fastening purposes.
  • a web 10 connects the base 27 with the reinforcing insert 9.
  • the side wall 11 has an elevation 34, which, viewed from the base 27, is just as high as the reinforcing insert 9. This end region with the elevation 34 has such a course that this the course of web 10 and reinforcing insert 9 is equal.
  • the reinforcing insert 9 is thus protected by the side wall 11, and in particular by the region of the side wall with the elevation 34.
  • the reinforcing insert 9 is located between two end regions of the two side walls 11 and 31.
  • the reinforcing insert 9 is enlarged from a different perspective (shown in the detail of the lock box 33). Based on FIG. 7 It becomes clear how a sheet has to be punched out and bent in order, among other things, to work out the reinforcement insert 9 together with the web 10 from the sheet metal.
