Definitions

  • the invention relates to a motor vehicle cover with a lever mechanism and a force-generating tool with the features mentioned in the preamble of claim 1.
  • tailgates and hoods and doors of vehicles are hinged to a vehicle body by means of hinges and hinges and can be equipped with power-generating tools for their manual, semi-manual or automatic opening and closing, for example with springs, gas springs or electromechanical / pneumatic / hydraulic drives , Under certain circumstances, take the joints, hinges and the force-generating aids so much space for themselves that they can be a significant impediment to loading and unloading of the vehicle or contribute to reducing the useful space of a trunk or engine compartment.
  • opening and closing can be done reliably and comfortably to the user even under various circumstances, such as a car leaning obliquely, both in a vertical trunk lid of a combination vehicle and in a horizontal trunk lid of a saloon.
  • DE 10 2006 019 478 A1 describes a tailgate mechanism of a vehicle, with a compact design of the tailgate mechanism is implemented by the fact that a force-generating gas spring acts on a force-translating lever with a short lever arm length and the same lever acts with its other longer lever arm on the lid to be moved.
  • Both lever arms of the force-translating lever are positioned relative to a common axis of rotation of the force-translating lever to each other at an angle selected such that the rotatably mounted gas spring when opening and closing the tailgate has to perform only a relatively small pivoting movement, whereby the gas spring takes up less space for itself ,
  • the gas spring is rotatably mounted on an inner surface along the tailgate and thereby can be installed concealed due to their relatively low deflection movement under the cowl of the tailgate.
  • the long lever arm of the force-translating lever acts with its distal end directly on an inner surface of the tailgate, whereby this end is not by a Joint, hinge or the like may be connected to the tailgate, but must slide on a dedicated inner surface of the tailgate.
  • the gas spring may be replaced by a motor drive and also be mounted on the vehicle body instead of in the tailgate.
  • the transition of the force on the tailgate of the effect with the long lever arm to force without the long lever arm should be felt by the user and affect his sense of comfort.
  • the sliding, connectionless power transmission structure thereby causes a significant drawback that, if instead of the gas spring, a motor drive is to be used, this can not bring the tailgate back, since the long arm lever would easily solve in this case from its contact point and the entire force transmitting lever would be pivoted about its axis of rotation in the inward direction.
  • EP 0 219 391 B1 discloses another compact mechanism for assisting the opening and closing operation of a lid such as a tailgate of a vehicle.
  • the tailgate lid is supported with the multi-link mechanism according to the invention only in the first phase of an opening operation of the tailgate, because in this phase at a small opening angle of the available lever is very short.
  • the multi-link mechanism has four lever arms rotatably connected to each other via four pivotal axis bearings, the major lever having at its end a slide bearing in the form of a wheel which rolls on a rolling surface of the vehicle body during opening of the tailgate lid and the substantial force between the tailgate lid and the vehicle body transmits, similar to the previously described publication DE 10 2006 019 478 A1 ,

  • the multi-joint mechanism is moved and lifted the sliding bearing of the rolling surface of the vehicle.
  • the multi-link mechanism is already ineffective and the power cylinder acts alone and directly in a conventional manner on the tailgate lid to be opened.
  • the proposed multi-link mechanism is housed in the space between the tailgate lid and the vehicle body, which is formed between a sealing curb of a trunk and the outer body surface for draining the rainwater.
  • the power cylinder is in this case mounted on the side facing away from the axis of rotation of the tailgate cover side, so that it crosses the opening angle range between the tailgate lid and the vehicle body with the lid open, which he may be in the way when the user wants to insert bulky items in the vehicle or remove ,
  • US 6,341,809 B1 discloses a motor vehicle cover hinged to a vehicle body. An actuation of the motor vehicle cover is effected via a lever mechanism, which can be actuated by means of a force-generating auxiliary means, so that the motor vehicle cover can be displaced from a closed to an open position.
  • the lever mechanism comprises two levers which are connected to each other via a hinge. One of the levers is connected to the motor vehicle lid via a first joint and the other lever via a third joint to the vehicle body. All joints of the lever mechanism are in this case in a plane of rotation, which coincides with the plane of rotation of the motor vehicle lid.

  • the degree of freedom of the rotational movement of at least one joint of the entire structure is limited to only one plane of rotation, so that the rotational movements of the remaining joints are also limited to this plane of rotation, because the rotational movement of the motor vehicle lid is already restricted by its hinge bearing to a plane ,
  • the plane of movement of the other joints of the overall structure with respect to the plane of rotation of the motor vehicle cover is inclined by an arbitrarily oriented, predetermined angle, which can be selected between a value of 0 ° and ⁇ 90 °.

  • the levers 5 and 6 are selected to be different lengths, whereby the vehicle-side hinge 7 can be positioned lower on the vehicle body 12. It can also be seen that the longer the vehicle-side lever 5 is selected, the shorter the second lever 6 may be, thereby allowing the designer to make the deflection angle ⁇ of the force-generating tool 2 smaller in order to release the force-generating aid 2 under the Covering the motor vehicle cover 1 installed concealed and only a small section for the freedom of movement of the lever 5, 5 '; 6, 6 'or possibly even 3, 3' to provide.
  • the concealed arrangement of the force-generating device 2 under the panel (not shown) of the motor vehicle cover 1 is advantageous because no visible parts are arranged laterally of the motor vehicle cover 1 and the space under the panel of a motor vehicle cover 1 then usually has enough unused space reserves.
