Definitions

  • the application relates to an actuatable flap arrangement.
  • Actuatable flap arrangements are known, for example, from the field of automobiles 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.
  • actuating the flaps for example, electromechanical, pneumatic or hydraulic actuators are used.
  • electromechanical, pneumatic or hydraulic actuators are used for actuating the flaps.

  • the essence of the invention is that a flap for opening and closing a housing opening of a housing by means of an actuating device actuated, that is pivotable.
  • a force storage element is provided to compensate for the weight of the flap.
  • the actuating device which has a linear actuator and a coupling element for connecting the linear actuator to the flap, exclusively to be interpreted and dimensioned such that only a force difference for opening and closing the flap provided becomes.
  • the energy storage element can be designed such that a required kinematics power requirement of the flap can be provided.
  • the actuating device and in particular the linear actuator has a system friction.
  • the system friction is provided such that a, in particular inherent, frictional force counteracts a closing force acting on the flap as a result of gravity.
  • the sum of the provided forces of the energy 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 embodied as a natural friction in a spindle actuator.
  • the linear actuator can be small, ie dimensioned with comparatively low power supply. In particular, only one of the force storage element exerted closing force or stopping force is overcome.
  • a flap assembly according to claim 2 allows improved accessibility of the housing opening.
  • a loading surface 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.
  • An accessibility from the side, ie in a direction parallel to the housing opening, is not affected by the actuating device substantially.
  • the actuating device is designed robust. Characterized in that the linear actuator is fixedly arranged on the housing, a force absorption and power transmission from the linear actuator is improved on the housing.
  • a flap arrangement according to claim 3 enables uncomplicated opening and closing of the housing opening by means of the hinged directly to the housing flap.
  • a flap assembly according to claim 4 enables improved handling of the actuating device.
  • the embodiment of the linear actuator as a spindle actuator represents a particularly robust embodiment of the actuator. In particular, it is possible not to perform the spindle actuator self-locking. This makes it possible to operate the flap manually, so without the spindle actuator is driven by a drive.
  • the spindle actuator allows longitudinal movement along a linear actuation direction, which is oriented in particular perpendicular to a flap pivot axis.
  • a flap assembly according to claim 5 guarantees increased safety requirements.
  • a required for operating the flap power requirements may be stored in the control unit.
  • this stored, maximum required power requirement which has, for example, a maximum required value for the electric power, is exceeded, this can serve as an indication of a malfunction of the flap or jamming of an object or a person.
  • the anti-trap protection of Flap arrangement is improved. The accident risk is minimized.
  • the control unit allows 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 assembly according to claim 6 has an increased stability and robustness. At the same time, the kinematics, in particular a pivoting of the flap, is not affected.
  • a flap assembly according to claim 7 is designed particularly stress. This makes it possible that the linear actuator can be dimensioned comparatively small.
  • the coupling element which may be designed in particular as a rod, in particular as a push rod, is designed to be small and in particular with a reduced load cross-section.
  • the coupling element is inconspicuous and substantially does not affect the aesthetic appearance of the opened housing. It is advantageous if the linear actuator is oriented to receive transversely to a linear actuation direction. Characterized in that the coupling element is articulated pivotably both on the linear actuator and on the flap, the pivotal movement of the flap can be transmitted directly and easily from the coupling element to the linear actuator, without the accessibility of the housing Opening is impaired.

In particular, this avoids that the flap unintentionally and in particular automatically opens, that is moved out of the closed position. At the same time, it is possible for the force storage element to exert a stopping force on the flap when the flap is in an open position. An open position of the flap is achieved, for example, when a minimum pivot angle of the flap is reached around the flap pivot axis. The stopping force is in particular contrary to the closing force and causes the flap to remain in an open position or to effect a further opening, ie an enlargement of the pivoting angle about the flap pivot axis.
  • the flap is inadvertently displaced back into the closed position.
  • the energy storage element is arranged in the closed position of the flap such that a torque is rectified with the closing movement.
  • the force exerted by the force storage element on the flap torque of the opening movement is rectified.
  • the energy storage element is arranged in the closed position of the flap on the flap in an over-dead center position. During opening of the flap, the force storage element is displaced through the dead center, resulting in a change in direction of the force exerted by the force storage element torque.
  • a flap assembly according to claim 9 comprises a simplified and improved embodiment of the energy storage element.

  • a folding arrangement according to claim 10 enables a flexible arrangement of the energy storage element on the housing on the one hand and on the flap on the other. In particular, a direct interaction of the energy storage element with the housing and the flap is possible.
  • a flap assembly according to claim 11 allows 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 a sliding of the flap relative to the housing. In particular, in a direction perpendicular to the housing opening a required space required is reduced.
  • a flap assembly according to claim 12 allows a straightforward and effective displacement of the flap relative to the housing.

  • 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. 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. The dead center is reached when the housing-fixed flap pivot axis 11, the energy storage element longitudinal axis 38 intersects. According to the embodiment shown, this is approximately at the pivot angle w of the flap 6 about the flap pivot axis 11 by about 5 ° in the counterclockwise direction, starting from the in Fig.
  • 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 connection 42 is rotated about the flap pivot axis 11 in the counterclockwise direction.
  • the upper connection 42 is then on a second side opposite the first side line of action 38, as shown in FIG Fig. 2 right of arranged the flap pivot axis 11.
  • the compressive force F caused by the pressure spring 37 of the energy storage element 35, which acts along the energy storage element longitudinal axis 38, causes a second torque M 2 with respect to the flap pivot axis 11.
  • 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 a directional reversal of the torque when passing through the dead center of the flap kinematics. This means that when the minimum pivot angle W min is exceeded, ie when the dead center of the flap kinematics is exceeded, the energy 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 , Pinching is avoided.
  • the energy storage element 35 is designed in particular such that it substantially equalizes the dead weight of the flap 6. It is also possible to provide more than one force storage element 35 in order to equalize the dead weight of the flap 6. In this case, it is possible, the individual energy storage elements small, d. H. with little power requirement, to dimension.
  • the electric motor 21 of the spindle actuator 15 can be dimensioned correspondingly small. In particular, the spindle actuator 15 has to apply only small forces in this case in order to allow opening or closing of the flap 6.
  • the push rod 16 may also be made small, in particular thin.
  • the flap 6 is characterized in that the spindle actuator 15 of the electrical control unit 14, a voltage pulse receives.
  • the electric motor 21 is activated, the spindle 22 is driven and the guide tube 25 is extended by means of the spindle nut 23 along the linear actuation direction 27.
  • 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 about the flap pivot axis 11 in the counterclockwise direction, that is opened. In the in Fig. 2 shown opened position, the flap 6 is pivoted relative to the closed position by the pivot angle w of about 115 °.
  • the flap arrangement 1 is closed, ie an inverted voltage pulse is transmitted to the spindle actuator 15 by the electrical control unit 14.
  • 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 actuating 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 experiences exclusively a linear movement and in particular no rotational movement. A required to pivot the flap 6 rotational movement is made possible by the push rod 16.
  • the space requirement of the spindle actuator 15 is fixed and changes during the opening and closing of the flap 6 exclusively along the actuation direction 27.
  • the spindle actuator 15 thus does not limit a loading cross-section of the flap assembly 1.
  • loading cross-section a free surface can be viewed on the housing opening 5, through which a loading can take place from outside the flap assembly 1 in the housing interior 3.
  • the actuating device 13 has the advantage that it is listed in the opening area of the flap assembly 1 optically inconspicuous. Also one lateral accessibility, ie accessibility in one direction transversely and in particular perpendicular to the plane according to Fig. 1 is at most slightly affected.
  • the flap assembly 1 is manually operable because the spindle actuator 15 is not designed to be self-locking. Characterized in that the spindle 21 is connected in the spindle actuator 15 via the gear 26 directly to the electric motor 21, the flap 6 is directly coupled to the Hall encoder 31 on the electric motor 21. This means that the electric control unit 14 also detects the manual operation 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 electric 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 allows the detection of the revolutions of the electric motor 21. The number of engine revolutions can be transmitted to the electrical control unit 14 and stored there.
  • the Hall encoder 31 is in particular mounted directly on the electric motor 21. Accordingly, it is possible to have a maximum opening position of the flap 6, which in Fig. 2 is shown to be determined by the number of rotations required for the electric motor 21. In particular, there is a direct relationship between the swivel angle w, a stroke of the spindle actuator 15 and the number of engine revolutions, that is, the Hall impulses, of the electric motor 21.
  • the flap assembly 1 has improved safety requirements. In particular, a pinch protection in the flap assembly 1 is improved.
  • the electrical control unit 14 for adjusting the flap 6 in the spindle actuator 15 occurring force curve and thus a required electrical power consumption is known.
  • 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 is not constant.
  • a required energy requirement is simulated in the electrical control unit 14. Accordingly, it is possible to supply the spindle actuator 15 of the electrical control unit 14 depending on the current pivot angle w or opening angle only with the actual necessary electrical power according to the determined power requirement. This can be done for example by means of different pulse width modulation at a constant supply voltage.
  • the electrical control unit 14 detects a deviating, in particular increased, power requirement of the spindle actuator 15. In this case, the electrical control unit interrupts 14 automatically the electrical voltage. The operation of the spindle actuator 15 is stopped. It is conceivable that the electrical control unit 14 is programmed such that in such a pinching case, an automatic opening movement by a few angular degrees with respect to a rotation about the flap pivot axis 11 takes place. By simulating the kinematics curve in the electrical control unit 14, a comparatively sensitive and direct anti-trap protection is provided.
  • the main difference with respect to the first embodiment is that the flap 6a is pivotally hinged to the housing 2a by means of a four-bar hinge 46.
  • the four-bar hinge 46 includes a first, in Fig. 6 shown above flap lever 47 and a second, in Fig. 6
  • the first flap lever 47 is pivoted about a first hinge pivot axis 49 on the housing 2a and about a second hinge pivot axis 50 on the flap 6a.
  • the second flap lever 48 is pivoted about a third hinge pivot axis 51 on the housing 2a and about a fourth hinge pivot axis 52 on the flap 6a.
  • the four-joint hinge 46 thus has four hinge pivot axes 49 to 52. Due to the use of the four-bar hinge 46, the opening movement of the flap 6a is advantageous and space-saving, in particular in a direction oriented perpendicular to the housing opening 5 direction feasible.
  • the linear actuator 15 is pivotally connected to the first flap lever 47 via the coupling element 16a about the second coupling element pivot axis 34a.
  • a stopper member 53 in the form of a rubber stopper 54 is provided, on which the flap 6a in the open position according to FIG Fig. 7 rests with a back.
  • the coupling element 16a is pivoted about the first coupling element pivot axis 33 to the linear actuator 15 pivotally.
  • the energy storage element 35a is pivoted at a first end about a first energy storage element pivot axis 43a to 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 force storage element pivot axis 44a. Also, the flap assembly 1a according to the second embodiment allows the advantageous operation of the flap 6a. In particular, the energy storage element 35a is advantageously hinged to the housing 2a, so that the flap 6a in the closed position according to Fig. 6 kept closed and in the open position according to Fig. 7 is stopped.
  • a compressive force caused by the compression spring 37 of the energy storage element 35a which acts along the energy storage element longitudinal axis 38a, causes a torque around the housing-fixed third hinge pivot axis 51 such that an opening or closing movement is supported.
  • Fig. 6 is a corresponding torque in a clockwise direction and according to Fig. 7 oriented counterclockwise.
