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 actuating element for manual emergency opening of the locking mechanism, the emergency actuating element being at least partially outside a lock housing is arranged and works by means of at least one transmission element on the locking mechanism for emergency opening.
- the locking mechanism and the electric opening drive are mostly placed inside the lock housing.
- the emergency actuation element is located at least partially outside of said lock housing.
- Motor vehicle locks and in particular motor vehicle door locks are nowadays, and increasingly for reasons of comfort, equipped with an electric or electromotive drive, at least for opening the locking mechanism, and consequently with an electric opening drive.
- motor vehicle locks are also referred to as electric locks.
- the locking mechanism In order to bring about the opening of the locking mechanism, the locking mechanism is consequently not mechanically coupled to an outside door handle, for example, as a rule. Rather, actuation of the outside door handle leads to sensor actuation, which in turn is used via a control unit to act upon the electromotive drive or electric opening drive, which in turn opens the locking mechanism.
- the electric motor drive usually works on a release lever, directly or indirectly.
- DE 10 2019 127 109 A1 describes a motor vehicle lock with emergency actuation, in which the electromotive drive is equipped with an emergency energy source for emergency actuation of the lever chain.
- the lever chain has an emergency operating lever, which has no function in its normal position and is transferred at least into its operating position, which closes the emergency operating lever chain, with the aid of the drive for emergency operation.
- This is intended to provide a simple and cost-effective emergency actuation of the lever chain.
- the design effort due to the electric motor drive and the emergency energy source is not insignificant.
- malfunctions as a result of an at least partially discharged emergency energy source cannot be completely ruled out.
- the procedure is such that a mechanical actuating lever chain for emergency opening of the locking mechanism is implemented in a motor vehicle door lock.
- an actuating element which blocks the actuating lever chain directly or indirectly during normal operation and releases it for emergency opening.
- the actuator is equipped with an electric motor with an output element.
- the actuating element can optionally be a flexible connecting element block or release for coupling the actuating lever chain to a handle. In this case, too, an additional electric motor drive is ultimately required in connection with an actuating lever chain for emergency actuation, which corresponds to an increased outlay in terms of design.
- a lock cylinder is provided and implemented outside a lock housing as an emergency actuation element.
- the locking mechanism can be opened in an emergency as an alternative to an electric motor drive.
- the locking cylinder is coupled to the release lever via a connecting rod.
- a further and significant problem is the fact that the emergency actuation element for manual emergency opening of the locking mechanism is often installed in a protected or concealed manner. This applies both to an attachment on the outside of an associated motor vehicle door and when the emergency operating element is present inside the relevant motor vehicle door. In fact, one will usually prefer such a procedure because the electric opening drive can fail, for example, following a crash and people inside still want to leave the motor vehicle. In contrast, manual handles or the like can be provided for opening the relevant motor vehicle door from the outside by, for example, arriving rescue personnel.
- 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, taking into account a simple, functional and cost-effective design, long-term functionality is ensured even over long time scales. Also should it must be ensured that the emergency operating element can be found safely and operated correctly.
- a generic motor vehicle lock is characterized in that the emergency actuation element has a covering cap that can be moved relative to a housing for the actuation of the transmission element, the covering cap indicating its emergency actuation function through its structural and/or visual design.
- the emergency actuation element In the context of the invention, first of all the emergency actuation element is generally and fundamentally designed in two parts.
- the emergency actuation element consists essentially of the housing and, moreover, of the covering cap that can be moved relative to the housing.
- the mobility of the cover cap ensures accessibility and also loading of the transmission element, as will be explained in more detail below.
- the covering cap indicates the emergency actuation function through its structural and/or visual design is of essential importance.
- the cover cap is designed in such a way that it is directly associated with the emergency actuation function, namely haptically and/or visually an associated motor vehicle door is attached or embedded in the relevant interior paneling. In most cases, this is done in such a way that the housing of the emergency actuation element is let into a corresponding recess in the inner door panel, so that the covering cap remains visible as the only element of the emergency actuation element to the outside.
- the cover cap is equipped with special structural and/or visual features that can be used to make the emergency actuation function visible and/or haptic Operator can be detected.
- the covering cap prefferably has at least one means of manual manipulation, such as a button, an eyelet or a handle, as an indication of the emergency actuation function.
- the manual manipulation means in question is designed to be exposed in relation to the cover cap, and can therefore easily be felt or haptically picked up by an operator and can consequently be interpreted as emergency actuation or indicate this.
- the covering cap can also be equipped with a visual indicator.
- a visual indicator This may be an imprint, a color code etc. as an indication of the emergency actuation function.
- corresponding lighting etc. are also conceivable in order to be able to guarantee the information function even in poor light conditions.
- a particularly advantageous variant is characterized in that an electric motor drive is provided for acting on the cover cap.
- the procedure is such that, for example in the event of a crash or subsequent to this, the electromotive drive is actuated and with its help the covering cap is acted upon. This can be due to the cap being swung open, removed from the housing or released in some other way, so that the transmission element becomes visible to an operator and can be manipulated in order to be able to use it to open the locking mechanism in an emergency.
- the invention is based on the knowledge that said crash using sensors, for example a crash sensor can be detected and at this point in time (still) enough electrical energy is available not only to apply safety measures such as an airbag, side impact protection, etc., but also the electric motor drive to apply the cover cap.
- the cap can be pivotally connected to the housing.
- the cover cap it is also possible for the cover cap to be releasably latched to the housing.
- the transmission element is also possible.
- the transmission element is releasably connected to the cap, an operator can easily grasp the transmission element after opening the cap and use it to open the locking mechanism in an emergency.
- the transmission element it is also possible for the transmission element to be permanently connected to the covering cap. In this case, a pivoting movement of the covering cap in relation to the housing ensures that the locking mechanism is simultaneously opened in an emergency via the transmission element.
- the operator pulling the cover cap, which has been detached from the housing, together with the transmission element, for example, in order to ensure the desired emergency opening of the locking mechanism in this way.
- the transmission element is advantageously a flexible transmission element, for example in the form of a cable, a Bowden cable, etc.
- the design is usually such that the transmission element is connected to an actuating lever for emergency opening of the motor vehicle lock.
- the actuating lever is regularly mounted inside the lock housing.
- the actuating lever is preferably guided to the outside via an opening in the lock housing.
- this opening can be sealed so that, in contrast to the prior art, there is no risk of dirt or water penetrating the interior of the lock housing via the opening in question. This is especially true in the event that the operating lever is mounted on the outside of the lock housing. In this case, too, the sealed opening may provide the connection of the actuating lever to the locking mechanism.
- a motor vehicle lock and in particular a motor vehicle door lock with a specially designed emergency actuation element is made available.
- This is regularly connected to a motor vehicle door on the inside.
- the last-mentioned variant can be implemented in particular for the case and can also be implemented in a theft-proof manner if the electromotive drive is provided for acting on the covering cap. Because this drive may ensure locking of the cover cap in normal operation, so that manipulation of the cover cap from the outside is not possible.
- the electric motor drive ensures that the covering cap is swung open or ejected from the housing.
- the emergency actuation element is inside the associated motor vehicle or is connected to the relevant motor vehicle door on the inside, it is also possible in principle to proceed in such a way that the electromotive drive basically releases the cover cap in normal operation and does not apply it. Only when a crash occurs does the electric motor drive ensure that the cover cap is opened relative to the housing, so that the transmission element as a whole is accessible.
- the procedure can also be such that the event of a crash indicates the emergency actuation function acoustically as an alternative or in addition to the loading of the electric motor drive.
- the event of a crash indicates the emergency actuation function acoustically as an alternative or in addition to the loading of the electric motor drive.
- an acoustic indication function for the emergency actuation element is also conceivable.
- This acoustic warning function amounts to the fact that in the event of a crash or immediately after the crash, an acoustic message is emitted via a radio or a hands-free system in the motor vehicle in such a way that the emergency operating element must be acted upon to open or emergency open the motor vehicle door in question for example on the driver's door in the area of an armrest or next to the mirror adjustment or somewhere else.
- the invention is based, as in the case of the actuation of the electric motor drive for the covering cap, on the knowledge that at the time the crash event is detected - still - sufficient electrical energy is available to, on the one hand, control the electromotive drive to act upon the covering cap and, on the other hand, for the to provide the previously described acoustic warning or information function. Either way, emergency opening is much easier compared to the prior art and with a hitherto unattainable level of accuracy. This is where the main advantages can be seen.
