Definitions
- the invention relates to a motor vehicle flap arrangement, in particular a motor vehicle door arrangement, with a wing that can be pivoted with respect to a body, also with an electromotive drive for the wing, and with a force sensor unit arranged in the power flow between the wing and the body, the sensor signals of which are evaluated by a control unit will.
- the flap can be a stain flap, a fuel filler flap, a trunk flap, a cargo space flap or even a bonnet.
- the flap is designed as a motor vehicle door. With the help of the electric motor drive, a wing belonging to the relevant flap is acted upon in order to pivot the flap in the simplest case with respect to the body. As a result, a door opening in a motor vehicle door is released or closed. In the case of a stain flap or trunk flap, a corresponding trunk opening is opened or closed.
- a vehicle door arrangement with a door drive which is characterized by a sensor device
- the sensor device can be designed as a force sensor.
- the force sensor With the help of the force sensor, the torsion of a drive shaft can be measured as a component of the electric motor drive.
- an inductive or capacitive sensor module is provided in detail, with the aid of which the distance to an eccentric disk is determined.
- a device for locking open doors or flaps of a motor vehicle is described.
- this has a sensor element that can be used to detect a torque that can be applied to the door.
- the usefulness of such locking devices for open doors is to be improved.
- the invention is based on the technical problem of further developing such a motor vehicle flap arrangement in such a way that, in particular, a trapping event can be safely and reliably detected.
- a generic motor vehicle flap arrangement within the scope of the invention is characterized in that the force sensor unit arranged in the force flow between the wing and the body is equipped with a mechanical transmission element that amplifies its sensor signals.
- the transmission element ensures in a mechanical way - and not electrically or electronically - that the sensor signals of the appropriately designed force sensor unit are amplified.
- the force sensor unit is generally designed in two parts.
- the force sensor unit is largely composed of a pushbutton element containing the transmission element and a force sensor.
- the probe element is in turn composed essentially of the translation element and a bending element.
- the design is also largely made such that the force sensor as a whole detects a spring-elastic force-induced deformation of the feeler element as its feeler path. That is, in order to measure the force acting on the wing with the aid of the electric motor drive, the feeler element is first of all deformed, namely in a resilient manner overall. This ensures permanent functionality of the pushbutton element.
- the deformation of the pushbutton element is force-induced, that is, depending on the force applied to the door leaf and made available by the electric motor drive.
- the invention is based on the assumption that the electromotive drive must exert an increased force on the wing when the wing is acted upon at the beginning, for example of a closing movement of the wing relative to the body, in order to reduce any flail friction forces of the wing's bearings relative to the body and its inertia overcome.
- the wing continues to close in relation to the body, an almost constant force can be expected which is applied by the electric motor drive in order to close the wing in relation to the body.
- the feeler path covered by the feeler element also changes. Since the force sensor detects the tactile travel of the tactile element, this change can be interpreted as a trapping event by the control unit evaluating the sensor signals.
- the trapping detected by the control unit is usually implemented in such a way that not only the electromotive drive is stopped immediately, but mostly also a reversing of the electromotive drive and consequently an opening movement of the sash is generated with the help of the electromotive drive.
- the force sensor unit is equipped with the mechanical transmission element that amplifies its sensor signals. That is, the translation element ensures that even the smallest deformations of the bending element are translated into more or less large tactile paths by the translation element, which in turn are sensed by the force sensor and converted into correspondingly large sensor signals.
- the probe element is composed essentially of the bending element and the translation element.
- the force-induced deformation of the probe element now generally corresponds to a flexible bending or bending of the bending element that is preferably force-proportional.
- a bending path associated with the bending or bending of the bending element generally depends proportionally on the force acting on the probe element.
- This force is made available by the electric motor drive or corresponds to the flow of force between the wing and the body.
- the bending path of the bending element is translated into the tactile path that is enlarged in comparison with the aid of the translation element.
- the slight bending path of the bending element is mechanically reinforced with the help of the translation element, so that, as it were, on the output side of the translation element, the tactile path, which is more or less significantly larger than the bending path, is observed.
- This enlarged tactile path is then in turn recorded by the force sensor and corresponds here to amplified sensor signals, in comparison to the situation in which the only slight deflection of the bending element would be recorded directly with the aid of the force sensor.
- the bending element is usually connected to a transmission lever as part of the electric motor drive.
- the bending element can be designed as part of the electromotive drive at an end of the transmission lever remote from the axis.
- the transmission lever is part of the electric motor drive.
- the transmission lever is mostly indirect or with the help of an electric motor immediately applied to pivoting movements about its axis of rotation. That is, the electric motor drive is mostly equipped at least with the electric motor already mentioned and possibly gear wheels, which in turn act on the transmission lever for pivoting movements with respect to its axis of rotation. Since the transmission lever also meshes on its short lever arm with a toothed rack acting on the wing, it becomes clear that the transmission lever as a whole is arranged in the power flow between the electric motor drive and the wing.
- the electromotive drive can be located inside the associated leaf or the door leaf in the case of a motor vehicle door. As soon as the electromotive drive executes rotary movements of its electric motor, these are transmitted via any interposed gears to the transmission lever and finally to the rack, which in turn ensures the desired rotary movements of the wing relative to the body. Because the electric motor drive moves along the rack. This results in a pivoting movement of the wing receiving the drive. Since the electromotive drive is rotatably supported on the body via the rack, the force sensor unit located on the transmission lever is not only in the power flow between the electromotive drive and the wing, but also in the power flow between the wing and the body.
- the transmission lever meshes on its short lever arm opposite the axis of rotation with the toothed rack acting on the wing.
- the transmission lever On its long lever arm, the transmission lever has the bending element at the end, which in turn is connected with its free end to a stationary bearing.
- the transmission lever is designed as a whole disk-like and on its circumference with the Probe element is equipped.
- the wing is pivoted relative to the body, as will be explained in more detail below with reference to the exemplary embodiment from.
- the bending element connected to the fixed bearing in the wing is deformed and completes the bending path mentioned above.
- the interposed spring causes a relative movement between the transmission lever and the transmission element or transmission lever, the size of which is proportional to the applied force. This relative movement between the transmission lever and the transmission lever can be detected and evaluated with the aid of the probe element.
- the procedure can also be such that one end of the transmission lever is connected to the bending element in the area of the previously described stationary bearing.
- the free end of the transmission lever completes the tactile path recorded by the force sensor. Since the bending element is realized on the one hand on the long lever arm of the transmission lever at the end and, on the other hand, the bending movement of the bending element is translated into the significantly increased tactile travel with the aid of the transmission lever, it is explained that overall increased sensor signals are observed compared to the case where the force sensor is directly scans the bending path of the bending element. This has the positive effects described above. This is where the main advantages can be seen. In the following the invention is explained in more detail with reference to a drawing showing only one embodiment; show it:
- FIG. 1 shows a motor vehicle flap arrangement according to the invention in the form of a motor vehicle door arrangement in an overview
- FIG. 2 shows a detailed view of the electric motor drive for the wing of the motor vehicle flap arrangement according to FIG. 1,
- FIG. 5 individual parts according to FIG. 4.
- a motor vehicle flap arrangement which, as evidenced by FIG. 1, is a motor vehicle door arrangement with a leaf 1.
- the wing 1 is designed as a motor vehicle door wing 1 and is connected to a body 2. This may take place in the area of an A-pillar of the body 2 in the example case, namely in a swivel joint.
- a rotary hinge 3 is implemented, with the aid of which the wing or motor vehicle door wing 1 can complete a travel s indicated in FIG. 1 with respect to the body 2.
- the leaf 1 or the associated motor vehicle door can be moved back and forth between an “open” and “closed” position.
- the open position of the leaf or motor vehicle door leaf 1 is shown by solid lines, whereas the dash-dotted line corresponds to the closed position of the leaf or door leaf 1.
- an electric motor drive 4, 5, 6, 7 is realized overall.
- the electromotive drive 4, 5, 6, 7 is arranged in the interior of the leaf or motor vehicle door leaf 1.
- a force generated with the help of the electric motor drive 4 to 7 for pivoting the leaf or motor vehicle door leaf 1 is now derived on a connecting element 8, which is a rack 8 in the context of the exemplary embodiment according to Figures 1 to 3, while the embodiment of Figures 4 and 5 works with a connecting rod.
- the connecting element is rotatably connected to the body 2 in the area of the rotary hinge 3 and is supported against the body 2. Since the electromotive drive 4 to 7 is located in the interior of the sash 1, overall rotary movements of an electric motor 4 as part of the electromotive drive 4 to 7 with the interposition of the connecting element or the rack 8 are transmitted to the sash 1, so that this the in Fig . 1 indicated Schwenkbe movements with respect to its rotary hinge 3 along the travel s can perform.
- the transmission lever 7 meshes with the connecting element acting on the wing 1 or the toothed rack 8 on its short fleece arm Hi compared to the axis A.
- the transmission lever 7 is equipped with a bending element 9 at the end of its long flexible arm H2.
- the bending element 9 defines, together with a transmission lever 10 designed as a transmission lever 10, a total of a feeler element 9, 10.
- the bending element 9 is in turn connected with its free end to a stationary bearing 11.
- the basic structure of the motor vehicle flap arrangement or the motor vehicle door arrangement also includes a force sensor unit 9, 10, 12, 13.
- the force sensor unit 9, 10, 12, 13 is in the force flow between the wing 1 and the body 2 or . between the Wing 1 and the electric motor drive 4, 5, 6, 7 arranged. Since the electric motor drive 4, 5, 6, 7 is in turn supported on the body 2 via the connecting element or the rack 8, it becomes clear that the force sensor unit 9, 10, 12, 13 is also in the power flow between the wing 1 and the body 2 is placed.
- the force sensor unit 9, 10, 12, 13 is equipped with the transmission element or transmission lever 10 which amplifies its sensor signals and which has already been addressed.
- the force sensor unit 9, 10, 12, 13 is largely designed in two parts.
- the force sensor unit 9, 10, 12, 13 is essentially composed of the probe element 9, 10 on the one hand and a stationary force sensor 12 on the other.
- the force sensor 12 is a sensor with the aid of which swiveling movements of the transmission element or transmission lever 10 indicated in FIG. 3 with respect to the force sensor 12 are detected.
- the force sensor 12 is designed as a fall sensor 12.
- a fall sensor is a fall arrester sensor through which current flows, at which a voltage is generated on the output side, specifically depending on how a magnetic flux oriented perpendicular to the fall sensor 12 changes.
- a magnet 13 is arranged opposite the fall sensor 12 according to the embodiment at the end of the translation element or translation lever 10. If the bending element 9 deforms or bends, according to the invention, the transmission element or the transmission lever 10 generates an enlarged pivoting movement in the area of the magnet 13 provided at the end, as indicated in FIG. 3 by corresponding arrows is.
- the fall sensor ⁇ detects a changing magnetic flux, which is largely proportional to the transmission lever 7 with the help of the electromotive Drive 4, 5, 6, 7 acting force F is.
- This force F leads opposite to the axis A on the stationary bearing 11 to a corresponding counterforce shown there.
- a torque is generated with respect to the axis A on the one hand, taking into account the short flexure arm Hi and, on the other hand, a greater torque on the long flexure arm H2.
- the short Flebelarm Hi and the associated torque acts on the connecting element or the rack 8 or the rod 8 and consequently the wing 1 via the long Flebelarm FI2.
- the torque on the long flexure arm FI2 leads to the bending element 9 being deformed as part of the feeler element 9, 10, as FIG. 3 indicates.
- the bending element 9 is a web-like extension of the transmission lever 7 at its end remote from the axis or at its long flexible arm FI2, namely at the end.
- Stops n on both sides ensure that the bending element 9 is only elastically deformed in relation to the axis A when a force or moment is applied.
- the deformations of the bending element 9 correspond to a minimal bending path b indicated in FIG. 3.
- This minimal bending path b is mechanically translated into a tactile path T that is much larger than this with the aid of the translation element or transmission lever 10. Since the transmission lever 10 consequently completes the sensing path T at the end, this also applies to the magnet 13 provided at the end of the transmission lever 10. This then leads to a correspondingly amplified sensor signal in the case of the fall sensor 12 compared to the situation that the force sensor or fall Sensor 12 would measure the bending path b of the bending element 9 directly.
- the force sensor s records a resilient force-induced deformation of the feeler element 9, 10 as its feeler path T.
- This force-induced deformation of the feeler element 9, 10 corresponds to a force-proportional flexible deflection of the bending element 9, which as a result completes the flexure path b.
- the bending path b is now translated with the aid of the translation element or transmission lever 10 into the tactile path T, which is enlarged in comparison, as is indicated schematically in FIG.
- the bending element 9 is arranged at the end of the transmission lever 7 remote from the axis. Since the transmission lever 7 is part of the electromotive drive 4, 5, 6, 7, a force F exerted by the electromotive drive 4, 5, 6, 7 on the wing 1 can be measured using the transmission lever 7 as described. For this purpose the transmission lever 7 is acted upon indirectly or directly to pivot movements about its axis of rotation A with the aid of the electric motor 4.
- the transmission element or the transmission lever 10 is connected with its one end in the area of the stationary bearing 11 to the bending element 9.
- the free end of the translation lever 10 completes the tactile path T recorded by the force sensor 12.
- the free end of the translation lever 10 is equipped with the magnet 13.
- the fixed bearing 11 is formed inside or on the wing 1.
- the transmission lever 10 has, for example, a reflective surface at the end is equipped, whose pivoting movements along the tactile path T are scanned with the aid of a light source belonging to the optoelectronic sensor in this case and, after reflection, is detected by a receiver belonging to the sensor.
- the sensor signals detected with the aid of the force sensor 12 as part of the force sensor unit 9, 10, 12, 13 are evaluated by a control unit 15 indicated in FIG. 3. Since the sensor signals of the force sensor ⁇ are significantly amplified compared to the situation that the force sensor 12 does not scan the tactile path T of the magnet 13, but rather the bending path b of the bending element 9, overall amplified sensor signals are recorded by the control unit 15. These amplified sensor signals can be evaluated in a particularly simple and targeted manner with regard to temporal gradients, so that in this way a sensitive detection of any possible trapping is possible, as was already described in the introduction.
- an electric motor drive 4, 5, 6, 7 is implemented which, with the aid of an electric motor 4, rotates its output worm 5 to a pinion 6 and Finally, the transmission lever 7 transmits, which in this way rotates about its axis A and forms the previously mentioned lever arms Hi and H2.
- a movement generated with the aid of the electric motor drive 4, 5, 6, 7 ensures that the bending element or spring element 9 interposed between the transmission lever 7 and the transmission element or transmission lever 10 is deformed, namely below Consideration of the minimum bending path indicated in FIG. 5 b.
- the transmission lever 7 is designed in the form of a disk and is equipped with the magnet 13 on its periphery. Force-induced movements of the magnet 13 about the axis A are detected with the aid of the sensor 12 connected to the transmission element 10 opposite the magnet 13 and transmitted to the control unit 15, not shown.
- the design is such that rotational movements of the electric motor 4 lead to a rotation of the transmission lever 7, which is ultimately transmitted to the transmission element 10 with the interposition of the spring or the bending element 9 and taking into account its deformation, to which the rod or the connecting element 8 is connected to the wing 1. That is, in this case, a relative angle with respect to the axis A is detected between the transmission lever 7 and the transmission element or transmission lever 10 by the combined effect of the magnet 13 and Hall sensor 12. If two Hall sensors 12 are implemented at this point, both the position of the transmission lever 10 and thus of the wing 1 and the force acting on the wing 1 can be measured simultaneously.
