Definitions
- Motor vehicle lock in particular motor vehicle door lock
- the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with a locking mechanism consisting essentially of a rotary latch and a pawl, furthermore with an electric opening drive for the locking mechanism, and with an emergency actuation element for manual emergency opening of the locking mechanism.
- Motor vehicle locks and in particular what are known as electric locks are increasingly being used in motor vehicles for reasons of convenience.
- such motor vehicle locks and in particular motor vehicle door locks are opened by an electric motor or electrically using the electric opening drive for the locking mechanism.
- an outside door handle or, in general, a switch on the outside door handle or independently thereof is actuated.
- a sensor can also be used instead of the switch.
- the opening request of a user willing to enter is typically detected by sensors and transmitted to a control unit, which in turn actuates the electric opening drive so that the (closed) locking mechanism can be opened by an electric motor in this way.
- the electric opening drive works, for example, on a release lever, which in turn lifts the pawl from its engagement with the rotary latch.
- the rotary latch can swing open with spring support or as a result of the opening force built up by door rubber sealing forces and releases a previously caught locking bolt.
- the associated motor vehicle door can be opened. This has basically worked.
- the emergency actuation element is mainly used when the electric or electromotive opening drive for the locking mechanism does not work or does not work adequately, for example due to a low on-board voltage of the associated motor vehicle. Comparable scenarios are observed for the case that, for example, the vehicle electrical system voltage is interrupted for maintenance purposes and access to the motor vehicle via the relevant motor vehicle door is still required.
- the emergency actuation element must be accessible in principle on the one hand, but must not be able to be manipulated from the outside on the other hand, in order to avoid improper opening of the associated motor vehicle door.
- an emergency release means is implemented as an emergency actuation element, whereby an operative connection between the electric or electromotive opening drive and a release lever can be released by actuation of the emergency release means.
- the emergency release means is essentially in the form of a pin.
- the emergency release means has a first connection end with a thread or a clip or latch connection.
- an actuation geometry is provided, which can be designed as a regular polygon, in particular a hexagon.
- the activation geometry of the emergency release means can be achieved via a recess.
- a suitable tool is required to operate the polygon or hexagon.
- 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 the actuation of the emergency actuation element and in particular its reset is as simple as possible and takes place without tools.
- a generic motor vehicle lock is characterized in a first variant characterized in that the emergency operating element is designed to be resettable from its operating position to its rest position by the force of a spring.
- the spring in question can be assigned directly to the emergency actuation element.
- the spring for example a helical spring or Coil spring is formed.
- the spring can alternatively or additionally also be designed as a ratchet spring.
- the invention is based on the finding that with the help of the spring, the emergency actuation element is reset or reset after it has been acted upon and the actuation position assumed thereby.
- the spring assigned directly to the emergency actuation element can ensure this.
- the spring force can also be made available by the pawl spring.
- the design is such that the emergency actuation element for manual emergency opening of the locking mechanism acts directly or indirectly on the pawl and lifts it from its latching engagement with the rotary latch.
- the pawl spring can be designed in such a way that it not only ensures that the pawl (again) is reset or reset in contact with the rotary latch after the pawl has been lifted out manually. Rather, within the scope of this variant, the pawl spring may at the same time also move the emergency actuating element, which interacts directly or indirectly with the pawl, from the actuating position to the rest position.
- the procedure is such that the emergency operating element is blocked in its operating position and is designed to be resettable manually into its rest position. That is, in this case, a corresponding manual actuation of the emergency actuation element ensures that this is manually transferred back from its actuation position to the rest position with a corresponding blockade or frictional inhibition.
- a handle connected to the emergency actuation element can be provided for manual resetting of the emergency actuation element.
- the handle in question may be a flexible handle that acts on the emergency actuation element.
- this flexible handle can be designed as a cable, cord, train, Bowden cable, etc.
- the handle and the emergency actuation element define a structural unit.
- a one-piece structural unit has proven to be particularly favorable.
- the emergency actuation element is made of plastic, for example, the handle in question can in this case be molded onto the actuation element made of plastic.
- the emergency actuation element can be acted upon not only manually, but also without tools.
- the emergency actuation element is reset purely manually and also without tools.
- handling is simplified overall and, according to the invention, there is basically no risk that a tool or special tool required at this point in the prior art is not available, has been lost, etc.
- the emergency actuation element is regularly covered, ie not visibly arranged on the motor vehicle door.
- Attaching and arranging the emergency actuation element behind a preferably detachable cover has proven to be particularly favorable here.
- this preferably detachable lining is the inner lining of an associated motor vehicle door.
- motor vehicle door is to be interpreted broadly within the scope of the invention. This means that this not only includes motor vehicle side doors, but expressly and explicitly also motor vehicle flaps, such as motor vehicle tailgates, motor vehicle front hoods, motor vehicle tank caps, motor vehicle covers to cover charging sockets, etc.
- the manual emergency opening in the example described can usually only be accomplished and implemented from the inside of the motor vehicle.
- the emergency actuation element can also be arranged behind a detachable outer paneling of the associated motor vehicle door, for example behind an impact protection strip or behind an outer door handle, a paneling of the outer door handle, etc. This means that the emergency actuation element is also accessible from the outside, so that if the electrical or electromotive opening drive, however, an opening of the relevant motor vehicle door is possible and can be implemented using the manually actuable emergency actuation element.
- the emergency actuation element is advantageously designed as an actuation pin that acts directly or indirectly on the pawl.
- an actuating pin has the fundamental advantage that it can be used to transmit relatively large thrust forces or actuating forces from an operator for manual emergency opening of the locking mechanism.
- the actuating pin advantageously has an actuating surface on the front. The actuating surface projects beyond the regularly cylindrical actuating pin on the peripheral side in the form of a plate-shaped actuating surface, so that in this way the required thrust forces can be applied by an operator when the actuating pin is acted upon in a linear manner.
- the plate-shaped actuating surface is simply pushed and pressed with a thumb.
- the emergency actuation element regularly reaches through an opening in a lock housing. Since, as a rule, not only the motor vehicle lock, but typically also the electric opening drive and a control unit including associated sensors are accommodated inside the lock housing is, the design is usually made so that the emergency actuation element passes through the relevant opening in the lock housing in a sealing manner. This ensures, in particular when the emergency actuation element is arranged behind a detachable outer covering, that no water, dust, etc., for example, can enter the lock housing from the outside via the opening. Rather, the lock housing ensures, as before and unchanged, a predominantly media-tight covering of the motor vehicle lock or the components located inside.
- the sealing passage of the emergency actuation element through the opening in the lock housing is generally realized in such a way that the actuation pin, which is advantageously realized in this context, has a graduated diameter.
- the actuating pin is usually in two parts with a front and in a cylindrical guide in the lock housing a cross-guide area and an adjoining reach-through area equipped with a smaller diameter.
- the reach-through area passes through the opening in the lock housing and carries the previously mentioned actuating surface on the head side.
- the guide area guided in the guide acts at the same time as a stop for the emergency actuation element, so that the spring restoring the emergency actuation element can advantageously be arranged as a helical spring between the actuation surface and the lock housing.
- Actuation of the emergency actuation element or actuation pin in the first variant now ensures that the relevant spring is compressed and can relax again after the actuation pin has been acted upon, thereby resetting or resetting the actuation pin.
- the guide area of the actuating pin accommodated in the guide is acted upon in a linear manner and thereby lifts the pawl directly or indirectly from its engagement with the rotary latch.
- the actuating pin is returned from its actuating position to the rest position with the aid of the spring.
- the guide area of the actuating pin moves with its front stop on the inside against the guide in the area of the opening in the lock housing.
- the design of the second variant is comparable with the only difference that in this context the actuating element or the actuating pin is held in its actuating position by frictional forces of the guide area within the guide or its return movement is inhibited.
- the operator In order to be able to reset the actuating pin in this case, the operator must manually reset the emergency actuating element or the actuating pin to the rest position. This is achieved in a particularly elegant manner thanks to the advantageously connected handle and its application.
- a motor vehicle lock is made available which, in particular, makes tool-free operation or tool-free actuation available in the course of manual emergency opening and when resetting the emergency actuating element. This makes operation particularly easy and intuitive and additional tools are not required. This is where the main advantages can be seen.
- the locking mechanism including electric opening drive in a perspective overview together with the Notbet decisivi transmission element and 4A and 4B the actuation of the emergency actuation element in the variant with a connected handle.
- a motor vehicle lock is shown, which is advantageously and not limitingly a motor vehicle door lock.
- the motor vehicle lock in question and in particular the motor vehicle door lock is accommodated in its entirety in a plastic lock housing 1 which can be seen particularly clearly in FIGS.
- a metallic lock case 4 is provided and implemented for storing the locking mechanism 2, 3.
- the motor vehicle lock or motor vehicle door lock shown is equipped with an electric or electromotive opening drive 5, 6, 7, which works indirectly on a release lever 8 and thus the locking mechanism 2, 3.
- the release lever 8 is rotatably mounted on the same axis as the pawl 2 about a common axis 9 .
- the release lever 8 and the pawl 2 are coupled to one another in a torque-proof manner.
- the electric opening drive 5, 6, 7 in turn has an electric motor 5, which works on the output side with a worm on a worm wheel 6 and causes it to rotate about an associated axis 10.
- a movement of the worm wheel 6 indicated in Fig. 3A in the counterclockwise direction indicated here during an electrical opening process ensures that the end of the release lever 8 resting on the helical contour 7 is moved to the left following the helical shape and according to the exemplary embodiment.
- This has a rotation of the release lever 8 to the joint with the pawl 2 axis 9 in clockwise as a result. Since the pawl 2 is coupled in a rotationally fixed manner to the release lever 8, the pawl 2 is also acted upon in a clockwise direction and thereby releases the catch 3 with which it was previously in latching engagement in the closed position indicated in FIG. 3A.
- the rotary latch 3 opens, optionally with the assistance of a spring, and releases a previously caught locking bolt which is not expressly shown.
- Flierzu corresponds to the electrical or electromotive opening process of the motor vehicle lock in question or its locking mechanism 2, 3.
- an emergency actuation element 11, 12, 13 is also implemented, namely for manual emergency opening of the locking mechanism 2, 3.
- This manual emergency opening of the locking mechanism 2, 3 is implemented and implemented according to the exemplary embodiment in such a way that the emergency actuation element 11, 12, 13 is within the framework 3A by an operator or vehicle user in the direction of the arrow shown in FIG. 3B, for example with a thumb.
- the associated pushing movement on the linearly movable emergency actuation element 11 , 12 , 13 causes the emergency actuation element 11 , 12 , 13 to work on a stop 14 arranged on the release lever 8 .
- the spring 15 is assigned to the emergency actuation element 11, 12, 13 according to the exemplary embodiment.
- the spring 15 is designed as a helical coil spring and at least partially surrounds the emergency actuation element 11 , 12 , 13 or the emergency actuation element 11 , 12 , 13 passes through the spring 15 .
- the emergency actuation element 11, 12, 13 is equipped with a front guide area 11 with a larger diameter and an adjoining reach-through area 12 with a smaller diameter.
- a plate-shaped actuating surface 13 is provided on the head side of reach-through area 12, which in this variant is designed such that a user presses the actuating surface 13 in question with his thumb, for example, and thereby activates the emergency actuating element 11, 12, 13 in the form of an actuating pin 11, 12, 13 in the representation according to FIG. 3B to the right from the illustrated rest position (FIG. 3A) to the illustrated actuating position (FIG. 3B).
- the spring 15 surrounds the reach-through area 12 and is arranged on a wall of the lock housing 1 in the area of an opening 16 in the lock housing 1 .
- the reach-through area 12 of the emergency actuation element or actuation pin 11 , 12 , 13 passes through this opening 16 of the lock housing 1 .
- the spring 15 is arranged between the plate-shaped actuating surface 13 and the lock housing 1 .
- the guide area 11 in turn dips into a guide 17 inside the lock housing 1 and can be moved back and forth linearly in this guide 17 .
- the guide area 11 Since the guide area 11 has a larger diameter than the reach-through area 12, the resetting movement of the emergency actuation element or actuation pin 11, 12, 13 - acted upon by the spring 15 - limited in that the guide area 11 moves with a head-side stop to a wall area of the lock housing 1 surrounding the opening 16 on the inside.
- the further second variant according to FIGS. 4A and 4B of the emergency actuation element or actuation pin of 11, 12, 13 has a comparable structure, but does not require the spring 15 for resetting. Rather, the procedure here is such that the emergency actuation element 11 , 12 , 13 is reset manually and a flange handle 18 connected to the emergency actuation element 11 , 12 , 13 is provided for this purpose.
- the flange handle 18 on the emergency actuation element 11, 12, 13 is a flexible flange handle 18, which according to the exemplary embodiment is designed as a cable or cord with an eyelet, so that a user can reset the emergency actuation element 11, 12, 13 with a finger through the eyelet 4A and 4B in the illustration according to FIG.
- 4B means that the emergency actuation element or the actuation pin 11, 12, 13 is moved to the left in the direction of the arrow indicated in FIG. 4B.
- 4A shows the emergency actuation element 11, 12, 13 in its rest position.
- the representation according to FIG. 4B corresponds to the actuating position of the emergency actuating element or actuating pin 11, 12, 13.
- the flange handle 18 and the emergency actuation element 11, 12, 13 are designed as a structural unit and, in particular, as a one-piece structural unit.
- the flexible flange handle 18 is molded onto the emergency actuation element 11, 12, 13, which consequently is a plastic injection-molded part.
- the pawl 2 is acted upon indirectly and indirectly in the exemplary embodiment according to FIG Pawl 2 conceivable.
- the emergency operating element or the operating pin 11 , 12 , 13 passes through the opening 16 in the lock housing 1 in a sealing manner.
- a seal 19 is provided for this purpose.
- the seal 19 is designed as a round seal embedded in the actuating pin 11 , 12 , 13 .
- the seal or O-ring 19 in question is located in the guide area 11 of the emergency operating element or operating pin 11, 12, 13. In this way, the invention ensures that no moisture, dust, etc. can penetrate the interior of the lock housing 1 via the opening 16 .
- the lock housing 1, like the emergency operating element 11, 12, 13, including the connected flange handle 18, is made of plastic, for example designed as a plastic injection molded part.
- the guide 17 for receiving the guide area 11 of the emergency actuation element 11, 12, 13 is also made of plastic. In this way, not only is a simple and cost-effective release position made available, but the emergency actuating element 11, 12, 13 is also accommodated in the interior of the lock housing 1 or the associated guide 17 with particularly little friction. Because at this point, a low level of plastic/plastic friction is typically observed.
- the emergency actuation element or the actuation pin 11, 12, 13 is arranged in a concealed manner behind a detachable cover 20, so it is not visible and is therefore also protected from manipulation.
- the detachable cover 20 In order to be able to act on the actuating pin 11, 12, 13 in question, the detachable cover 20 must first be opened or removed. According to the exemplary embodiment, this is an inner paneling of an associated motor vehicle door or an outer paneling or both. This has already been described in the introduction. Reference List
