Definitions

  • the application relates to an actuatable flap arrangement.
  • Actuatable flap arrangements are known, for example, from the automotive sector in the form of a tailgate or from the industrial sector, where machines and systems can be closed, for example for safety reasons, by means of an actuatable flap.
  • Such flap arrangements are disclosed in DE 10 2011 011 094 A1 .
  • EP 0 962 236 A2 For example, electromechanical, pneumatic or hydraulic actuators are used to actuate the flaps.
  • different, sometimes conflicting requirements are placed on an actuatable flap arrangement and on its handling.
  • an actuatable flap arrangement with the features specified in claim 1 in a manner which is not obvious.
  • the essence of the invention is that a flap for opening and closing a housing opening of a housing can be actuated, ie pivoted, by means of an actuating device.
  • an energy storage element is provided to compensate for the weight of the flap.
  • the actuating device which is a linear actuator and a coupling element for connecting the linear actuator to the flap has to be designed and dimensioned only in such a way that only a force difference for opening and closing the flap is provided.
  • the force storage element can be designed in such a way that a required kinematic force requirement of the flap can be provided.
  • the actuation device and in particular the linear actuator to have system friction.
  • the system friction is provided in such a way that an, especially inherent, frictional force counteracts a closing force acting on the flap due to gravity.
  • the sum of the forces provided by the force storage element and the frictional forces is particularly sufficient to hold the flap in any position relative to the housing.
  • the system friction can be designed as a natural friction in a spindle actuator.
  • the linear actuator can be dimensioned small, ie with a comparatively small range of services. In particular, only a closing force or hold-open force exerted by the energy storage element has to be overcome.
  • the flap arrangement enables a particularly advantageous handling in that the energy storage element exerts a closing force on the flap in a closed position of the flap, so that the flap remains in the closed position. In particular, this prevents the flap from opening unintentionally and in particular automatically, ie moving out of the closed position. At the same time, it is possible for the energy storage element to exert a holding force on the flap when the flap is in an open position. An open position of the flap is reached, for example, when a minimum swivel angle of the flap around the flap swivel axis has been reached.
  • the hold-open force is in particular opposed to the closing force and causes the flap to remain in an open position or on further opening, ie an increase in the swivel angle around the flap swivel axis. In particular, this prevents the flap from being inadvertently moved back into the closed position.
  • Such an advantageous use of the energy storage element can be made possible in particular in that the energy storage element is arranged in the closed position of the flap in such a way that a torque is aligned with the closing movement. In contrast, in the opened position of the flap, the torque exerted by the energy storage element on the flap is rectified by the opening movement. In particular, the energy storage element is arranged in the closed position of the flap on the flap in a dead center position.
  • the energy storage element is displaced through the dead center, which results in a change in direction of the torque exerted by the energy storage element.
  • a closing force required to close the flap can only be applied by the energy storage element.
  • the pinch protection is improved, in particular in the critical pinching area of a lower closing area of the flap arrangement.
  • the linear actuator is fixed to the housing. This enables improved access to the housing opening.
  • a loading area defined by the housing opening or a loading cross section of the housing is not impaired by the actuating device, that is to say the linear actuator and the coupling element.
  • accessibility from the side, ie in a direction parallel to the Housing opening is essentially not affected by the actuating device.
  • the actuating device is robust. The fact that the linear actuator is arranged fixedly on the housing improves the force absorption and power transmission from the linear actuator to the housing.
  • the energy storage element is articulated with a first end pivotable about a first energy storage element pivot axis on the housing and with a second end pivotable about a second energy storage element pivot axis on the flap.
  • the flap can be hinged directly to the housing. This enables the housing opening to be opened and closed easily.
  • the linear actuator is listed as a spindle actuator.
  • the spindle actuator enables a longitudinal movement along a linear actuation direction, which is in particular oriented perpendicular to a flap pivot axis.
  • a control unit which is in signal connection with the actuating device and in particular with the linear actuator.
  • a power requirement required to actuate the flap can be stored in the control unit.
  • maximum required power requirement which for example has a maximum required value for the electrical power
  • the pinch protection of the flap arrangement is improved. The risk of accidents is minimized.
  • the control unit enables the linear actuator to be stopped as soon as a maximum power value defined in the control unit is exceeded, so that a closing movement of the flap is automatically interrupted.
  • a flap arrangement according to claim 4 has increased stability and robustness. At the same time, the kinematics, in particular the pivotability of the flap, are not impaired.
  • a flap arrangement according to claim 5 is designed to meet particularly high demands. This makes it possible for the linear actuator to be of comparatively small dimensions.
  • the coupling element in particular as a rod, in particular can be designed as a push rod, is small and in particular is designed with a reduced load cross-section.
  • the coupling element is inconspicuous and essentially does not impair the aesthetic appearance of the opened housing. It is advantageous if the linear actuator is oriented to accommodate transverse to a linear actuation direction. Because the coupling element is pivotably articulated both on the linear actuator and on the flap, the pivoting movement of the flap can be transferred directly and easily from the coupling element to the linear actuator without the accessibility of the housing -Opening is impaired.
  • the linear actuator can be fixedly attached to the housing, since the push rod articulated in two directions enables the flap to pivot.
  • a flap arrangement according to claim 6 has a simplified and improved embodiment of the energy storage element.
  • the energy storage element it is possible for the energy storage element to be integrated in the linear actuator and in particular in a spindle actuator. This makes it possible for the available installation space and in particular a loading area of the housing to be additionally enlarged. It is also possible to integrate a friction element into the energy storage element. Such a friction element can support the compensation of the valve's own weight.
  • a flap arrangement according to claim 7 enables an advantageous flap movement.
  • a space-saving opening movement of the flap is possible.
  • the opening movement which is made possible by means of a four-joint hinge, essentially corresponds to the flap being pushed open relative to the housing. In particular in a direction perpendicular to the housing opening, the required space is reduced.
  • a flap arrangement according to claim 8 enables an uncomplicated and effective displacement of the flap relative to the housing.
  • a flap arrangement according to claim 9 enables an advantageous integration of a force storage element, as well as an advantageous articulation of the linear actuator to the four-bar hinge.
  • a braking device which provides a braking force which counteracts the closing force acting on the flap as a result of the force of gravity.
  • the brake can be set and / or actuated in a direction-dependent manner such that the braking force of the brake can be set and / or set in a direction-dependent manner.
  • the sum of the provided forces of the energy storage element and the braking device is in particular sufficient to cover the flap in one hold any position in relation to the housing.
  • the braking device simplifies the handling of the flap arrangement.
  • a flap arrangement according to claim 11 is particularly stable.
  • a linear actuator is attached to the housing in such a way that it can absorb lateral forces.
  • the transverse forces are oriented transversely and in particular perpendicularly to a longitudinal axis of the linear actuator.
  • the transverse forces are oriented in a flap plane predetermined by the flap.
  • the guided displacement of the flap in relation to the housing is stabilized.
  • Such a flap arrangement is robust.
  • An actuatable flap arrangement designated as a whole by 1, comprises a housing 2 which delimits a housing interior 3.
  • the housing 2 comprises a housing frame 4 which, according to the exemplary embodiment shown, has a plurality of one another may have connected profile elements such as profile tubes or extruded profiles.
  • the housing frame 4 is essentially cubic or cuboid. Side surfaces, an upper and a lower cover surface can for example be closed or clad with plate-shaped elements.

  • a connection 42 for the pivotable articulation of the energy storage element 35 is pivotable about a first energy storage element pivot axis 43 on the housing frame 4 of the housing 2 and about a second energy storage element - Swivel axis 44 is pivotally arranged on the fastening element 8 of the flap 6.
  • the energy storage element 35 it is also possible for the energy storage element 35 to have only a gas spring or a mechanical spring. It is also possible, and in particular depending on an installation situation of the energy storage element 35, that a tension spring is used instead of the compression spring 37.
  • the energy storage element 35 enables a particularly advantageous handling of the flap 6 on the flap arrangement 1.
  • a closed position of the flap 6 acts a closing force in the energy storage element 35 on the flap 6.
  • the energy storage element longitudinal axis 38 is the line of action of the pressure force F of the energy storage element 35.
  • the energy storage element 35 is in particular installed on the flap arrangement 1 such that a pressure force F is always exerted regardless of the position of the flap 6.
  • a compressive force F acts along the force storage element longitudinal axis 38 on the first force storage element pivot axis 43 and on the second force storage element pivot axis 44.
  • the line of action 38 intersects the first and second energy storage element pivot axes 43, 44.
  • the compressive force F causes the energy storage element 35 to always strive in an extended arrangement according to Fig. 2 to be relocated.
  • the compressive force F acts on the first and second energy storage element pivot axes 43, 44.
  • the force torque element 35 exerts the first torque M 1 about the flap pivot axis 11, which acts in a clockwise direction.
  • the upper connection 42 of the energy storage element 35 is in the closed position of the flap 6 with respect to the line of action 38 on a first side, according to FIG Fig. 1 left, arranged by the flap pivot axis 11.
  • an upper connection 42 of the energy storage element 35 is immersed over a dead center. Dead center is reached when the flap pivot axis 11 fixed to the housing intersects the longitudinal axis 38 of the energy storage element. According to the exemplary embodiment shown, this is approximately at the pivot angle w of the flap 6 about the flap pivot axis 11 by approximately 5 ° in a counterclockwise direction, starting from Fig. 1 shown closed position of the flap 6 reached.
  • the swivel angle at which the dead center of the flap kinematics is reached is also referred to as the minimum swivel angle W min .
  • the second torque M 2 is oriented in the counterclockwise direction.
  • the second torque M 2 is thus oriented counter to the first torque M 1 .
  • the displacement of the flap 6 allows the torque to be reversed when the dead center of the flap kinematics is passed. This means that when the minimum swivel angle W min is exceeded, i.e. when the dead center of the flap kinematics is exceeded, the force storage element 35 exerts a holding force on the flap 6 so that the flap 6 remains open and in particular does not close unintentionally and automatically . This prevents pinching.
  • the energy storage element 35 is in particular designed in such a way that it essentially equalizes the dead weight of the flap 6. It is also possible to provide more than one energy storage element 35 in order to equalize the weight of the flap 6. In this case, it is possible to make the individual energy storage elements small, i. H. with low power requirements.
  • the electric motor 21 of the spindle actuator 15 can be made correspondingly small. In particular, the spindle actuator 15 only has to exert small forces in this case in order to enable the flap 6 to be opened or closed.
  • the push rod 16 can also be made small, in particular thin.
  • the flap 6 is opened in that the spindle actuator 15 receives a voltage pulse from the electrical control unit 14 receives.
  • the electric motor 21 When an electrical voltage is applied, the electric motor 21 is activated, the spindle 22 is driven and the guide tube 25 is extended along the linear actuation direction 27 by means of the spindle nut 23.
  • the linear extension movement is transmitted from the push rod 16 to the fastening element 8 and thus to the flap 6.
  • the flap 6 is rotated counterclockwise about the flap pivot axis 11, that is to say opened.
  • the flap 6 is pivoted relative to the closed position by the pivot angle w of about 115 °.
  • the flap arrangement 1 is closed correspondingly in reverse, ie an inverted voltage pulse is transmitted from the electrical control unit 14 to the spindle actuator 15.
  • the electric motor 21 and the spindle 22 are rotated in the opposite direction and the guide tube 25 is retracted via the spindle nut 23 along the linear actuation direction 27.
  • the spindle actuator 15 is fixedly attached to the housing 2 and in particular to the housing frame 4, the spindle actuator 15 only experiences a linear movement and in particular no rotational movement. A rotary movement required for pivoting the flap 6 is made possible by the push rod 16.
  • the space requirement of the spindle actuator 15 is fixedly defined and changes during the opening and closing of the flap 6 exclusively along the actuation direction 27.
  • the spindle actuator 15 therefore does not limit a loading cross-section of the flap arrangement 1.
  • a loading cross-section a free area at the housing opening 5 can be viewed, through which loading can take place from outside the flap arrangement 1 into the housing interior 3.
  • the actuating device 13 has the advantage that it is optically inconspicuous in the opening area of the flap arrangement 1. Also one lateral accessibility, ie accessibility in a direction transverse and in particular perpendicular to the plane of the drawing Fig. 1 is only slightly affected.
  • the flap arrangement 1 can be actuated manually since the spindle actuator 15 is not designed to be self-locking. Because the spindle 21 in the spindle actuator 15 is connected directly to the electric motor 21 via the gear 26, the flap 6 is directly coupled to the Hall encoder 31 on the electric motor 21. This means that the electrical control unit 14 also detects the manual actuation of the flap 6. In particular, it is possible to detect a current position of the flap 6, even if the current position has been set manually.
  • the electrical control unit 14 has a reference. This means that in this position the electrical control unit 14 can be set to the value zero, for example.
  • the Hall encoder 31 enables the revolutions of the electric motor 21 to be recorded. The number of revolutions of the motor can be transmitted to the electrical control unit 14 and stored there.
  • the Hall encoder 31 is in particular attached directly to the electric motor 21. Accordingly, it is possible to set a maximum opening position of the flap 6 in Fig. 2 is shown by the number of revolutions of the electric motor 21 required for this. In particular, there is a direct relationship between the swivel angle w, a stroke of the spindle actuator 15 and the number of motor revolutions, that is to say the Hall pulses, of the electric motor 21.
  • the flap arrangement 1 has improved safety requirements. In particular, pinch protection in the flap arrangement 1 is improved.
  • a force curve occurring for adjusting the flap 6 in the spindle actuator 15 and thus a required electrical power requirement is known in the electrical control unit 14.
  • the force curve or the power requirement can be determined by means of the electrical control unit 14. Due to the kinematics of the flap arrangement 1, the force curve and thus the power requirement along an opening or closing movement of the flap 6 are not constant.
  • a required energy requirement is simulated in the electrical control unit 14. Accordingly, it is possible to supply the spindle actuator 15 from the electrical control unit 14 with the actually necessary electrical power in accordance with the determined power requirement, depending on the current swivel angle w or opening angle. This can be done, for example, by means of different pulse width modulation with a constant supply voltage.
  • the electrical control unit 14 detects a different, in particular increased, power or power requirement of the spindle actuator 15. In this case, the electrical control unit interrupts 14 automatically the electrical voltage. The actuation of the spindle actuator 15 is stopped. It is conceivable that the electrical control unit 14 is programmed in such a way that in such a case of jamming an automatic opening movement takes place by a few angular degrees with respect to a rotation about the flap pivot axis 11. The simulation of the kinematics in the electrical control unit 14 provides a comparatively sensitive and direct protection against trapping.
  • the essential difference compared to the first exemplary embodiment is that the flap 6a is pivotably articulated on the housing 2a by means of a four-bar hinge 46.
  • the four-bar hinge 46 includes a first, in Fig. 6 Flap lever 47 shown above and a second, in Fig. 6 Flap lever 48 shown below.
  • the first flap lever 47 is articulated on the housing 2a about a first hinge pivot axis 49 and on the flap 6a about a second hinge pivot axis 50.
  • the second flap lever 48 is articulated on the housing 2a about a third hinge pivot axis 51 and on the flap 6a about a fourth hinge pivot axis 52.
  • the four-joint hinge 46 thus has four hinge pivot axes 49 to 52. Due to the use of the four-joint hinge 46, the opening movement of the flap 6a can be carried out advantageously and in a space-saving manner, in particular in a direction oriented perpendicular to the housing opening 5.
  • the linear actuator 15 is articulated on the first flap lever 47 via the coupling element 16a about the second coupling element pivot axis 34a.
  • a stop element 53 in the form of a rubber stopper 54 is provided on the first flap lever 47, on which the flap 6a in the open position according to FIG Fig. 7 with a back.
  • the coupling element 16a is pivotally articulated on the linear actuator 15 about the first coupling element pivot axis 33.
  • the energy storage element 35a is pivoted at a first end about a first energy storage element pivot axis 43a on the housing frame 4a of the housing 2a. At a second end, the energy storage element 35a is pivotally connected to the second flap lever 48 about a second energy storage element pivot axis 44a.
  • the flap arrangement 1a according to the second exemplary embodiment also enables the flap 6a to be actuated advantageously.
  • the energy storage element 35a is correspondingly advantageously articulated on the housing 2a, so that the flap 6a in the closed position according to FIG Fig. 6 kept closed and in the open position according to Fig. 7 is stopped.
