Definitions

  • the invention relates to a motor vehicle door lock, with a body-side motor vehicle door lock and associated lock housing and a hood or door-side lock holder bracket, or vice versa, further with at least one opening/closing drive for a lock in the motor vehicle door lock or lock housing, and with a handle for manual emergency opening of the lock .
  • the motor vehicle door lock in question is not limited to a motor vehicle front hood lock or motor vehicle tailgate lock or the aforementioned motor vehicle door lock represents a component of the motor vehicle door lock in question in addition to the additionally provided lock holder bracket.
  • Such motor vehicle door locks initially have the two basic components, namely the motor vehicle door lock or the lock housing with the locking mechanism located therein, essentially consisting of a rotary latch and a pawl, on the one hand, and the associated lock holder bracket or locking bolt on the other.
  • the lock housing is usually provided on the body side, for example in the area of a front hood or tailgate opening in or on the body.
  • the motor vehicle door lock is designed as a motor vehicle front hood lock.
  • the latter variant corresponds to a motor vehicle tailgate lock.
  • the lock holder bracket is located on the hood or door side.
  • the reverse can also be done.
  • the lock holder bracket is connected to the body, whereas the lock housing and with it the associated motor vehicle door lock are one mounted on the hood or door side.
  • the lock housing is found on the body side and the lock holder bracket on the hood or door side, as is generally the case in the DE 10 2016 117 282 A1 is described by the applicant.
  • the opening/closing drive for the locking mechanism is provided in the lock housing.
  • the opening drive ensures that, for example, in a motor vehicle front hood lock, a pawl as part of the locking mechanism consisting of a rotary latch and pawl and, if necessary, a drive pawl are opened.
  • the drive pawl is part of the closing drive and, together with the closing drive, ensures that, for example, a locking device that is manually in the pre-locking position is transferred to the main locking position and closed.
  • a handle is provided with the help of which the locking mechanism can be opened manually via a connecting element. Actuating the handle consequently results in the connecting element being acted upon and in this way the locking mechanism undergoes an emergency opening.
  • a closing drive is provided, which pivots the rotary latch as part of the locking mechanism from the pre-locking position into the main locking position.
  • An emergency release lever is also provided, with the help of which there is a total in the area Fig. 2 emergency opening shown can be carried out.
  • the catching position corresponds to the fact that motor vehicle front hood locks, for example, also have a catch hook in addition to the locking mechanism consisting of a rotary latch and pawl.
  • the catch hook in question is pivoted into its closed position, in which it engages behind the locking bolt or lock holder bracket.
  • the locking bolt or lock holder bracket is therefore doubly secured, on the one hand by the rotary latch held in the closed position with the help of the pawl and on the other hand by the catch hook mentioned.
  • the locking mechanism is acted upon with the help of the opening drive.
  • a handle provided inside a motor vehicle body can be provided, which acts on the opening drive and ensures the electromotive opening of the locking mechanism.
  • the opening drive only ensures that with its help the pawl is generally lifted from its engagement with the rotary latch and can accordingly open the locking mechanism in the lock housing.
  • the catch hook still ensures that that the locking bolt or lock holder bracket is held in place.
  • the catch position described above corresponds to this.
  • catch hook lock In order to be able to completely open such a catch hook lock, it is also necessary to pivot the catch hook that still secures the lock holder bracket so that the lock holder holder and thus the hood or flap are released.
  • the pivoting of the catch hook is regularly carried out by a vehicle driver, who, for example, has to reach through a gap between the body and the hood on the front of the motor vehicle in order to operate the catch hook. This gap is created by the fact that the hood is set up after the described opening process of the locking mechanism with the help of the opening drive at least until the catching position is reached. This is ensured by a spring or by any restoring forces from a door or hood seal.
  • motor vehicle front hood locks can usually only be opened by an electric motor using the opening drive from inside the motor vehicle body (while stationary). This is no longer possible if the on-board electrical system voltage is insufficient. This means that in this case a vehicle driver can still get into the motor vehicle because, for example, a locking cylinder with a mechanical key or emergency key ensures that at least the motor vehicle door is opened.
  • the battery which can often be accessed via the front hood, is not accessible.
  • the invention as a whole aims to provide a remedy here.
  • the invention is based on the technical problem of further developing such a motor vehicle closure in such a way that a functionally reliable mechanical emergency opening is provided, without the risk of unwanted hood or door openings.
  • a motor vehicle door lock with the features of claim 1 is proposed according to the invention. Further preferred embodiments of the invention are defined in the subclaims.
  • a generic motor vehicle door lock within the scope of the invention has a handle to which a locking element is assigned, the position of which is queried using at least one sensor.
  • the handle is usually mechanically coupled to the locking mechanism via a connecting element.
  • the lock can be opened manually in an emergency.
  • the locking mechanism and, if necessary, a drive pawl are usually opened as part of a closing drive.
  • a catch hook can also be opened.
  • the lock holder bracket is completely released and the hood can be opened.
  • the handle is assigned the locking element.
  • the locking element can be moved into a position that at least locks and releases the handle.
  • the locking element generally interacts with a stop on the connecting element to limit the path of the connecting element.
  • the handle usually has an extension that at least partially acts on the locking element.
  • the design is such that when the handle is acted upon to emergency open the locking mechanism of the motor vehicle door lock, the extension works on the locking element and acts on it at least to such an extent that the sensor querying the position of the locking element is also acted upon.
  • the locking element does not (yet) ensure that the handle is blocked becomes. Rather, this is done with the help of a locking drive assigned to the locking element. As soon as the locking drive acts on the locking element, the locking element moves from its position releasing the handle to the position locking the handle.
  • the handle In this locked position of the handle, the handle can only be acted upon taking into account a first stroke, with the help of which the pawl is opened from its engagement with the rotary latch and, if necessary, a drive pawl.
  • the additional and usually provided catch hook still ensures that the lock holder bracket is secured and held in place. Only when the locking element is moved into its position releasing the handle with the help of the locking drive can the handle perform a second stroke following the first stroke and also open the catch hook. Now the hood can be swung open completely.
  • the locking element is designed in detail as a predominantly linearly guided locking slide.
  • the locking slide has a locking lug which moves into a position that locks the handle.
  • the locking lug In this locking position, the locking lug is located in front of a stop on the connecting element between the handle and the locking mechanism, so that loading of the handle up to the first stroke is limited by the fact that the stop on the connecting element moves against the locking lug and consequently the loading of the handle up to to the first stroke is limited in this way.
  • the catch hook still ensures that the rotary latch is secured. After completing this first stroke of the handle, the hood moves into a catching position.
  • the blocking element is generally equipped with a contour that acts on the sensor. This is particularly recommended due to the fact that the sensor is typically used as a micro switch or switch in general is trained.
  • the contour provided on the locking element or locking slide now ensures that the sensor or switch or microswitch is acted upon with the help of the contour as soon as the locking element or the locking slide is acted upon with the help of the handle or the extension on the handle.
  • the sensor or switch is still acted upon as before and unchanged as soon as the locking drive transfers the locking element into the position that locks the handle.
  • Signals from the sensor are usually processed by a control unit.
  • the control unit now acts on the opening/closing drive for the locking mechanism and optionally the locking drive for the locking element. For example, if the handle is acted upon and generates a signal on the sensor, the control unit can interpret this to mean that the opening/closing drive for the locking mechanism is acted upon to open the locking mechanism, according to the invention when the motor vehicle is at a standstill.
  • the control unit generally additionally evaluates signals from a speed sensor and/or at least one door contact switch.
  • the control unit determines a significant speed based on signals from the speed sensor, the control unit generally acts on the locking drive for the locking element in such a way that the locking element is transferred from its previously occupied position releasing the handle into the position locking the handle. This ensures that any impact on the handle while driving will only result in the locking mechanism and, if necessary, the drive pawl being opened.
  • the associated front hood goes into its catching position.
  • the catch hook still ensures that the rotary latch is secured so that the front hood cannot move into its fully open position.
  • the hood or front hood can be moved into the catch hook position using a motor with the help of the opening/closing drive, for example to take a person who is there accidentally with it To supply fresh air. If the opening/closing drive for the locking mechanism fails, the hood or flap in question can also be moved into the catch position mentioned using the handle for manual emergency opening of the hood.
  • the signal from the sensor can also be stored according to the invention and used for a time-delayed action on the opening/closing drive and optionally the locking drive.
  • an operator may press the handle for manual emergency opening while driving in order to indicate his or her wish to open the hood or flap.
  • This opening request is not met while driving because the control unit acts on the locking drive for the locking element through the additional evaluation of the signals from the speed sensor immediately when the motor vehicle starts up.
  • the locking element is therefore in its position locking the handle while the motor vehicle is driving.
  • control unit Only when the vehicle has come to a standstill does the control unit evaluate the stored signal from the sensor so that the opening/closing drive is now actuated to open the hood or flap, without the handle experiencing or having to be operated again . In fact, the stored signal from the sensor is evaluated by the control unit to the effect that when the vehicle is at a standstill, the opening/closing drive first opens the locking mechanism and then the catch hook.
  • the locking drive for the locking element is designed to be self-locking.
  • the control unit can de-energize the locking drive after reaching a position that locks or releases the handle. This results in unnecessary energy consumption to power the locking drive Reaching one of its two end positions is avoided.
  • he has Locking drive in this context usually via a worm wheel, which generally ensures the self-locking design of the locking drive as a whole.
  • a motor vehicle door lock which provides a functionally reliable mechanical emergency opening, without the risk of unwanted hood or door openings.
  • Querying the position of the locking element with the help of the sensor provides information about any opening request for manual emergency opening by an operator as well as whether the locking element is in a position that releases the handle or a position that blocks the handle.
  • the signal from the sensor can now advantageously be evaluated by the control unit depending on the speed and, for example, be implemented in such a way that when a certain vehicle speed is reached or a threshold for a predetermined vehicle speed is exceeded, the locking element is transferred to its position that locks the handle.
  • the control unit may then de-energize the associated locking drive for the locking element.
  • the locking element maintains its position blocking the handle by self-locking until the locking drive acts on the locking element in the direction of its releasing position in relation to the handle. This is usually only the case when the motor vehicle has come to a standstill after a previous journey.
  • a possibly stored signal from the sensor assigned to the locking element can now be interpreted as a request to open the flap or hood in such a way that the opening/closing drive opens the hood immediately after the vehicle has stopped (for a longer period of time) without additional pressure on the handle. If necessary, it will also be evaluated whether the engine is running, so as not to misinterpret, for example, a waiting position of the motor vehicle as being at a standstill.
  • the signal of at least one door contact switch is also evaluated with the help of the control unit.
  • the engine is switched off and, for example, the door contact switch also reports that the vehicle door has been opened, this can be interpreted to mean that the vehicle has actually come to a standstill and the hood or flap can be opened safely. This is essentially where the main advantages can be seen.

  • a movement of the locking element 13 can be sensed with the help of the sensor 26.
  • the sensor 26 is designed as a switch or microswitch that interacts with a contour 27 on the locking element 13.
  • the position of the locking element or locking slide 13 is queried.
  • an impact on the handle 5 can also be sensed via the sensor 26.
  • the extension 28 on the handle 5 works on the locking element 13 and acts on it at least partially. This means that an action on the handle 5 leads to the locking element 13 being at least so far it is acted upon that the contour 27 on the locking element 13 interacts with the sensor 26 and generates a signal from the sensor 26 to be evaluated by the control unit 22.
  • a sensor (not shown) assigned to the handle 5 may transmit its actuation to the control unit 22.
  • the control unit 22 now acts on the opening/closing drive 4 for the locking device 1, 2 depending on signals from the sensor 26 and/or the sensor assigned to the handle 5.
  • the signal from the sensor 26 and optionally the signal from the sensor assigned to the handle 5 Sensor evaluated with the help of the control unit 22 to the effect that the opening/closing drive 4 opens the locking mechanism 1, 2.
  • the speed sensor 23 reports that the vehicle is at a standstill to the control unit 22 and, in addition, at least one door contact switch 24 reports a motor vehicle door that has been opened, for example by a vehicle driver.
  • the locking drive 14, 15, 16 can also be acted upon with the help of the control unit 22.
  • a signal from the speed sensor 23 generally leads to the locking drive 14, 15, 16 being acted upon with the aid of the control unit 22 in such a way that the locking element 13 leaves its previously occupied position releasing the handle 5 and immediately into the handle 5 is transferred to the locking position in order to prevent accidental opening of the hood or front hood 10 while driving by acting on the handle 5.
  • the signal from the sensor 26 is stored. This is done with the help of the control unit on this In this way, the signal from the sensor 26 is used for a time-delayed action on the opening/closing drive 4. For example, applied If a vehicle driver uses the handle 5 for manual emergency opening while driving, the locking element 13 in its locking position ensures that the handle 5 only performs the first stroke A and opens the pawl 2 and, if necessary, the drive pawl. The catch hook 12 still remains in its position securing the rotary latch 1.
  • the control unit 22 interprets this as a standstill of the vehicle and may then act on the opening/closing drive 4 with a time delay without the handle 5 being acted upon again in order to both the pawl 2 or the lock 1, 2 as well as the catch hook 12 to open.
  • the locking drive 14, 15, 16, which has already been described in detail, is designed to be self-locking overall. As a result, the control unit 22 can de-energize the locking drive 14, 15, 16 after assuming a position that locks or releases the handle 5. In this way, unnecessary power consumption is avoided and a vehicle battery is not put under unnecessary strain.
  • the design is such that the handle 5 for manual emergency opening of the locking mechanism 1, 2 works with an extension 28 on the locking element 13 during its pivoting movement about the rotation axis Z perpendicular to the plane of the drawing.
  • This clockwise movement of the handle 5 corresponds to the fact that the extension 28 coupled to the handle 5 adjusts the locking element 13 in the linear direction, pushing it "downward” according to the exemplary embodiment.
  • the linear movement of the locking element 13 only takes place to such an extent that the locking element 13 cannot interact with the stop 20 on the connecting element 6, as shown in FIG Fig. 3 is shown.
  • the handle 5 in the releasing position shown there, the handle 5 is able to open not only the pawl 2 and possibly the drive pawl, but also the catch hook 12.
  • the lock holder bracket 3 is released as a whole when the emergency opening is realized in this way. Because the handle 5 or the slide 11 completes both the stroke A and then the stroke B. Here, the slide 11 comes into engagement with an emergency opening lever 30, which in turn acts on the pawl 2.
  • the emergency opening lever 30 is basically unnecessary.
  • the control unit 22 ensures that the locking drive 14, 15, 16 is acted upon. You can see this in the transition from the Fig. 3 to Fig. 4 .
  • the action on the locking drive 14, 15, 16 now results in the locking element 13 moving into its position blocking the handle 5 in front of the stop 20, as shown in FIG Fig. 4 is reproduced. If the handle 5 now moves from this locking position of the locking element 13 in the Fig. 4 is acted upon in the sense already described, that is to say in the sense of a clockwise movement about the axis Z for emergency opening, the slide 11 only performs the stroke A. As a result of this, the pawl 2 and possibly the drive pawl are opened, but not the catch hook 12.
  • the hood 10 assumes its partially opened position according to the dash-dotted illustration in the Fig. 1 on (catching position).
  • the handle 5 cannot be acted upon again, for example after the vehicle has come to a standstill necessary.
  • the signal from the sensor 26 is stored and ensures a time-delayed action on the locking drive 14, 15, 16.
  • the hood 10 remains in the partially opened position shown in dash-dotted lines while driving Fig. 1 .
  • the stored signal from the sensor 26 is implemented by the control unit 22 in such a way that the locking drive 14, 15, 16 is transferred from its position that blocks the handle 5 to the releasing position.
  • the stored signal of the sensor 26 can also ensure a time-delayed action on the opening drive 4, which opens the locking mechanism 1, 2 and also the catch hook 12, so that the lock holder bracket 3 is released and the hood 10 as a whole is in its fully open position according to the dashed representation can be transferred.
  • the complete opening of the hood or front hood 10 is carried out when the vehicle is at a standstill by, for example, the vehicle driver manually opening the catch hook 12 through the gap formed in the catch position between the front hood 10 and the body.
  • FIG. 8A - C and 9 A variant is shown in which the handle 5 is equipped in two parts with an interior lever 5a and a Bowden cable lever 5b. Both levers 5a, 5b are connected to one another in an articulated manner and are biased by a spring or leg spring 29.
  • a spring or leg spring 29 This means that in the Fig. 8A Indicated pulling movements on the interior lever 5a in the releasing position of the locking element 13 are transferred to the Bowden cable lever 5b (cf. Fig. 8B ). If, on the other hand, the locking element 13 is in its locking position, the Bowden cable lever 5b is blocked and the interior lever 5a is pivoted against the force of the leg spring 29 (cf. Fig. 8C ).
  • the handle 5 is equipped in two parts with the interior lever 5a and the Bowden cable lever 5b.
  • the two levers 5a, 5b mentioned are pivotally coupled to one another with the spring 29 interposed.
  • the spring 29 is dimensioned such that, under normal forces, the Bowden cable lever 5b acts on the interior lever 5a is taken along.
  • the connecting element 6 is blocked using the locking element 13, as in the Figures 8A to 8C is indicated, an action on the interior lever 5a results in the consequently blocked Bowden cable lever 6b not being moved.
