Definitions
- the invention relates to a motor vehicle door with a motor vehicle door lock, furthermore with at least one first electric motor drive for the motor vehicle door lock, and with an electrical emergency energy source for the relevant or first drive.
- the electromotive drive for the motor vehicle door lock generally ensures that the motor vehicle door lock in question can be opened electrically.
- the electric motor drive is supplied with current from, for example, a main energy source inside an associated motor vehicle body.
- the so-called normal operation corresponds to this.
- there is also an emergency operation specifically in the event that the main energy source is not available. This can be the case when the main energy source is simply discharged.
- Emergency operation is also possible in the event that the electrical connection from the electric motor drive to the main energy source is interrupted, for example in the event of an accident or crash.
- motor vehicle door is to be understood broadly in the context of the invention. This includes, inter alia, motor vehicle side doors, motor vehicle sliding doors, but also motor vehicle tailgates, motor vehicle loading flaps, etc. So in the end, all motor vehicle doors or motor vehicle flaps on or in the motor vehicle are covered. As a rule, this includes, in particular, motor vehicle side doors which are opened electrically for reasons of convenience or are equipped with a closing drive and enable an operator to access the interior of the motor vehicle and thus its operation. In the prior art, there are already various approaches to how to deal with such an emergency operation. DE 20 2016 105 621 U1 deals with a keyless entry and ignition system for vehicles.
- a reserve module is addressed in order to supply a lock with the required electrical energy with the aid of a reserve power supply.
- the reserve module can be attached at a suitable location, for example in an interior space of a door leaf of the motor vehicle door in question.
- the design is such that the reserve module is accessible by removing an outer panel in order to enable the replacement or maintenance of the reserve module. Furthermore, this should enable the replacement of the reserve power supply or emergency energy source, if this is necessary.
- the reserve module is also provided in or on the motor vehicle door leaf.
- the generic prior art according to DE 10 2018 100 551 A1 is about a motor vehicle locking device.
- This has an electrically actuated actuator which is set up at least to unlock or open a motor vehicle door.
- an emergency actuation device is provided for the motor vehicle door in question.
- the emergency actuation device is designed to be functionally and structurally independent of the motor vehicle and has an external energy source for the actuator.
- the external energy source can be part of a mobile device.
- an energy interface is provided, with the aid of which the external energy source can be connected to the actuator. The energy interface can work in a contactless or contact-bound manner.
- the energy interface is usually arranged on the outside at an accessible point of the motor vehicle, for example in the outside mirror or also in the outside door handle or also a door panel of an associated motor vehicle door. Such a location is at least then problematic if the motor vehicle is heavily soiled or has been damaged in the area of the energy interface as a result of an accident.
- DE 11 2013 000 504 T5 has made known a vehicle access system which, among other things, has an external power supply.
- the external energy supply can be charged via an energy transmission medium.
- an emergency energy source is available for the energy supply of an authentication, a control and the electrical locks.
- DE 10 2015 205 951 A1 deals with an electric lock with an actuating device for a motor vehicle lock.
- a second electric drive can be operated if the first electric drive has not been able to open the locking mechanism.
- the second electric drive is larger than the first electric drive.
- the second electric drive can also work as a closing aid or act as such.
- the locking mechanism should be able to be acted upon with much greater forces than in normal operation. The same applies in emergency operation in the event that the motor vehicle door has been deformed as a result of an accident.
- the associated actuation device comprises a drive wheel, whereby an opening first force can be introduced into the locking mechanism by rotating the drive wheel in a first direction. If the drive wheel is rotated in the opposite, second direction, a second force, which is greater than that, can be introduced into the locking mechanism.
- a larger transmission ratio is also conceivable.
- the state of the art has basically proven itself when it comes to generally providing emergency operation. This emergency operation can become necessary if the main energy source inside the motor vehicle body has failed. This may be the case due to unloading or an accident.
- Various approaches in the state of the art are being pursued. DE 10 2015 205 951 A1 already works with different drives for normal operation and emergency operation. Different transmission ratios can also be used.
- DE 20 2016 105 621 U1 pursues a separate and self-sufficient reserve module which must be attached in the interior of the motor vehicle door or door leaf and is generally accessible via a cover.
- the present invention is based on the technical problem of further developing such a motor vehicle door in such a way that one with regard to the Observed manufacturing costs and the required installation space optimized solution is made available.
- the invention proposes in a generic motor vehicle door within the scope of the invention that the emergency energy source is arranged in an operationally required component for attachment in or on a door leaf.
- the emergency energy source is therefore expressly not part of a separate reserve module. Rather, the emergency energy source is integrated into an obligatory component. As a result, among other things, and as a rule, a separate housing for the emergency energy source is omitted, because it is located and arranged inside the component that is required anyway.
- This component is an operationally required component, that is, one which is mandatory and indispensable for the intended operation of the door leaf and thus the motor vehicle door as a whole.
- the component can advantageously be an outside door handle and / or an inside door handle.
- the emergency energy source can alternatively or additionally also be attached in the door mirror.
- the component is designed as a motor vehicle door lock.
- the emergency energy source can be accommodated, for example, in the lock housing for the motor vehicle door lock, which is already implemented at this point.
- the component can also be designed as a control unit.
- a control unit is usually found in every motor vehicle door or in the interior of the associated door leaf, specifically to control the motor vehicle door lock, possibly the window regulator, a side airbag, etc.
- the obligatory housing is available for inclusion the control unit is also available within the scope of the invention as a housing for the emergency energy source or is used as such.
- the operationally required component in question is designed as a window regulator, loudspeaker, airbag, etc. to be attached in or on the door leaf.
- the emergency energy source can be integrated into the mandatory window regulator or its housing. Integration of the emergency energy source into the loudspeaker, airbag or side airbag, etc. is just as possible and is also covered by the invention.
- the emergency energy source uses the one or more operationally required components for mounting in or on the door leaf. That is, according to the invention, there is also the possibility of dividing the emergency energy source into different sub-units, which are accommodated and arranged in differing and operationally required components for attachment in or on the door leaf. For example, it is conceivable that part of the emergency energy source is located in the outside door handle, while the other part of the emergency energy source is arranged inside the control unit. As a result, the emergency energy source can be equipped with the necessary energy storage capacity in order to provide electrical opening of the motor vehicle door lock in every case in emergency operation.
- the electrical emergency energy source can be a conventional accumulator.
- so-called “supercaps”, ie capacitors with a particularly high capacity, are used here.
- the one or more capacitors can - as described - for example on the outside door handle or the control unit or several other of the operationally required components for attachment in or on the door leaf are distributed.
- a second electromotive drive in addition to the first electromotive drive, can be provided for the motor vehicle door lock.
- the design is usually made in such a way that the first electric motor drive is fed from the main energy source.
- the second electromotive drive is fed only by the emergency energy source.
- both the first electromotive drive and the second electromotive drive it is also possible for both the first electromotive drive and the second electromotive drive to be fed from the main energy source in normal operation and from the main energy source and the emergency energy source in emergency operation.
- the design in this case is usually made in such a way that the first electric motor drive ensures that the locking mechanism of the motor vehicle door lock is acted upon quickly and thus that it is opened quickly.
- a low torque is usually required in normal operation.
- the second electromotive drive provides a much higher torque in emergency operation in order to be able to open the door leaf in question electrically even in the event of any deformation after a crash. It is not important here to ensure that the locking mechanism of the motor vehicle door lock is opened quickly; the opening can also be done slowly take place as long as the electrical opening is ensured at all via the increased torque on the part of the second drive.
- a further variant provides that the first electromotive drive has a transmission which, in emergency mode, operates on the locking mechanism of the motor vehicle door lock. That is, in normal operation, the electric motor drive acts on the locking mechanism in question - without the gearbox - directly and here ensures that the motor vehicle door lock is opened quickly. On the other hand, in emergency operation or exclusively in emergency operation, the gearbox following the electric motor drive is used, which in this case ensures that the locking mechanism is acted upon with increased torque in emergency operation compared to normal operation.
- the procedure at this point is such that the first electromotive drive is equipped with a gearbox with at least two gear stages.
- a first switching stage of the gearbox following the electric motor drive ensures that the locking mechanism is opened quickly during normal operation.
- the first gear stage provides a relatively low torque and is fast running, i.e. it is usually equipped with a gear ratio.
- the second switching stage is used in emergency operation. The second switching stage is usually used to reduce the electric motor drive in order to provide the increased torque required to open the locking mechanism in emergency mode.
- the design is usually made such that the fluff energy source acts on the first electric motor drive during normal operation.
- the flap energy source provides the electrical power to the first drive. It also ensures that the first gear stage is used in normal operation in the variant in which the first electric motor drive is mandatory with the gearbox. If, however, emergency operation occurs, this emergency operation ensures that the second electric motor drive in the variant with the two drives is fed from the emergency energy source.
- the emergency operation with the emergency energy source also ensures that the gearbox that was previously not used in normal operation in the other variant with only one first electric motor drive now generally reduces the speed of the electric motor drive in order to increase the torque in emergency operation to open the locking mechanism on the output side to provide the motor vehicle door lock. Finally, the emergency operation ensures that the second shift stage of the gearbox is used, with the first electromotive drive being energized in this case with the aid of the emergency energy source.
- a load switch is usually provided.
- the emergency energy source is electrically connected to the associated first or second drive in emergency operation.
- the design is usually made in such a way that the load switch is actuated in accordance with an activation signal.
- the activation signal switches between normal operation and emergency operation and ensures that the emergency energy source is electrically connected to the electric motor drive via the then closed load switch.
- the signal of an already present and obligatory crash sensor can be evaluated as the activation signal.
- the crash sensor is used to detect excessive negative accelerations, that is to say decelerations of generally more than 5 g.
- Safety systems such as airbags, side impact protection, seat belt tensioners, etc. are usually activated as a function of a signal from the crash sensor.
- the signal from the crash sensor is also used as an activation signal for actuating the load switch, so that In this way, the emergency energy source for power supply is available, even if, as a result of the crash, the main energy source does not or no longer supplies sufficient electrical energy.
- the activation signal ensures that the gearbox is engaged or that the gear is switched to the second gear stage. This is where the main advantages can be seen.
- Fig. 1 The motor vehicle door according to the invention schematically and
- 2A-2C show different variants of the electromotive drive for the associated motor vehicle door lock.
- a motor vehicle door is shown, which is a motor vehicle side door 1 in the context of the example shown and not by way of limitation.
- the motor vehicle door or motor vehicle side door 1 has a motor vehicle door lock 2, which is equipped with an obligatory locking mechanism 3 comprising a rotary latch and pawl.
- a first electromotive drive 4 for the motor vehicle door lock 2 or its locking mechanism 3 is implemented.
- the electromotive drive 4 is located in the interior of a housing of the motor vehicle door lock 2.
- the variant of the motor vehicle door lock 2 as shown in FIG. 2A shows another second electromotive drive 5, which also operates on the locking mechanism 3.
- the variant according to FIG. 2B is also equipped with a gear 6 following the electric motor drive 4.
- the motor vehicle door lock 2 uses a gearbox 7 following the electric motor drive 4, with the aid of which the locking mechanism 3 can be acted upon.
- the basic structure of the motor vehicle door or motor vehicle side door 1 in the example also includes an electrical emergency energy source 8. With the aid of the electrical emergency energy source 8, the electromotive drive 4, 5 can be acted upon, as will be explained in more detail below.
- the electrical emergency energy source 8 in the context of the exemplary embodiment is one or more so-called “supercaps”, that is to say capacitors with a particularly high capacity.
- the emergency energy source 8 can wholly or partially take over the function of a main energy source 12 which is arranged inside the motor vehicle body (not shown) and is only indicated in FIG. 1.
- the motor vehicle door or motor vehicle side door 1 in the example is equipped overall with a door leaf 9 which can be opened and closed with the aid of a door handle 10 or outer door handle 10 relative to the motor vehicle body, not shown in detail.
- a control unit 11 can be seen in the door leaf 9.
- the control unit 11 is used to control any security systems arranged inside the door leaf 9, a window lifter and the door lock 2.
- the control unit 11, like the motor vehicle door lock 2 according to the exemplary embodiment, has the main energy source 12 supplied with the necessary electrical energy in normal operation.
- the emergency energy source 8 is arranged in an operationally required component 2, 10, 11 for attachment in or on the door leaf 9.
- the operationally required component 2, 10, 11 for the motor vehicle door 1 is, within the scope of the exemplary embodiment, the motor vehicle door lock 2, the outer door handle 10 and finally the control unit 11. That is, these components 2, 10, 11 are mandatory for the intended operation of the door leaf 9 and consequently the motor vehicle door 1.
- further components such as a window lifter, Loudspeaker, airbag, outside door mirror, inside door handle, etc. belong, as has been explained in the introductory description.
- the emergency energy source 8 is arranged in the operationally required component 2, 10, 11 for attachment in or on the door leaf 9, specifically in the control unit 11.
- the emergency energy source 8 can alternatively or additionally also be installed in the motor vehicle door lock 2 as well as in the outside door handle 10.
- the emergency energy source 8 uses the component 2, 10, 11 in question, which is operationally required anyway, for its attachment, with a housing, which is usually mandatory in this context, also providing protection of the emergency energy source 8 in question from environmental influences.
- the emergency energy source 8 is charged in normal operation via the electrical connection between the control unit 11 and the main energy source 12.
- the control unit 11 can now switch between normal operation and emergency operation.
- the control unit 11 In normal operation, the control unit 11 is supplied with the required electrical energy with the aid of the main energy source 12.
- the control unit 11 is acted upon by an emergency activation signal 13 which, according to the introductory explanations, can originate from a crash sensor, for example. This is indicated by a schematic switch shown in FIG. 1.
- the switch in question is open. Only when a crash is observed and the crash sensor accordingly emits a corresponding signal is the schematic switch in the control unit 11 closed and, in turn, ensures that a signal is sent to the Control unit 11 connected load switch 14 is also closed.
- the load switch 14 is located in the interior of the outside door handle 10, but can in principle also be arranged elsewhere in the interior of the door leaf 9. In any case, the load switch 14 is only active when the control unit 11 has received the emergency activation signal 13, for example as a result of a crash, and accordingly switches from normal operation to emergency operation.
- the emergency energy source 8 now provides the electrical energy supply to the door lock 2. Because in the event of a crash, the connection between the control unit 11 and the flake energy source 12 indicated in FIG. 1 is usually interrupted. In principle, however, the flap energy source 12 can also at least partially provide for the further electrical energy supply of the control unit 11 as well as the outside door handle 10 and the motor vehicle door lock 2 in the example case or ensure this.
- FIG. 2A-2C show three different variants of the motor vehicle door lock 2 according to the invention.
- the first electromotive drive 4 works in normal operation on the locking mechanism 3 and at this point ensures that the locking mechanism 3 can be opened quickly.
- the first electromotive drive 4 provides a relatively low torque in the example, which is sufficient for this purpose in normal operation.
- the first electromotive drive 4 is supplied with the required electrical energy with the aid of the main energy source 12.
- the second electromotive drive 5 is activated, which in principle can also be used in normal operation, for example as a closing drive in the interior of the motor vehicle door lock 2.
- the second electromotive drive 5 is regularly supplied with the necessary electrical energy with the aid of the emergency energy source 8.
- the second electromotive drive 5 works with a high reduction and usually relatively slowly, so that a possibly deformed door leaf 9 can be opened with the aid of the second electromotive drive 5.
- the procedure is such that the first or only electric motor drive 4 located there in normal operation directly, ie. H. without the interposed gear 6, the locking mechanism 3 works.
- the main energy source 12 again provides the electrical energy supply for the electric motor drive 4.
- the locking mechanism 3 is again opened quickly and with a relatively low torque. If, on the other hand, emergency operation occurs, the transmission 6 is switched on.
- the electric motor drive 4 is regularly supplied with the necessary electrical energy with the aid of the emergency energy source 8.
- the electric motor drive 4 usually works with reduction to the locking mechanism 3 via the then interposed transmission 6, so that the locking mechanism 3 can be opened slowly and with an increased torque compared to normal operation, even in emergency mode.
- the variant of the motor vehicle door lock 2 according to FIG. 2C works in a manner comparable to the variant according to FIG. 2B.
- the electromotive drive 4 is followed by a gear, this time a gearbox 7 with two gear stages or a gearbox.
- the electric motor drive 4 works via the first switching stage on the locking mechanism 3.
- the desired rapid opening corresponds in normal operation with a low torque.
- a switch is made to the second switching stage, which in this case is usually used for reducing the electric motor drive 4 and for applying the locking mechanism 3 provides increased torque to normal operation.
- the control unit 11 ensures that the emergency energy source 8 can supply the motor vehicle door lock 2 with the required electrical energy via the then closed load switch 14.
- the control unit 11 in the exemplary embodiment ensures that, in the variant according to FIG. 2A, there is a switchover from the first electromotive drive 4 to the second electromotive drive 5.
- the control unit 11 ensures that the transmission 6 is switched on in emergency operation.
- the control unit 11 finally ensures that a switch is made from the first gear stage of the transmission 7 in normal operation to the second gear stage in emergency operation.
