Definitions

  • the present invention relates to a tailgate balancing device, intended to equip a motor vehicle.
  • the balancing of these tailgates is usually carried out using pneumatic cylinders or balancers placed, most generally, in the side gutters of the vehicle, these balancers being intended to compensate for the weight of this tailgate and to facilitate its opening and closing.
  • Patent BE-A-643,216 describes and represents a manual device for actuating a skylight comprising a return mechanism, one end of which is linked to the skylight and the other end of which is articulated on the frame by the 'via a bent return lever comprising two unequal arms and articulated at its elbow on said frame around an axis substantially parallel to the axis of articulation of the skylight, the end of one of said arms being in contact with a flat raceway fixed on the skylight.
  • the patent US-A-2 544 500 describes and represents a similar device for actuating a shutter.
  • GB-A-1 167 150 describes and represents another similar device for actuating a cover.
  • the device which has just been described makes it possible, thanks to the presence of the bent lever, to obtain an automatic opening of the skylight as soon as the lock which keeps it closed is released.
  • the present invention relates to an improvement to the device described in patents BE-A-643,216, US-A-2,544,500, GB-A-1,167,150, and which aims in particular, in its application to a vehicle tailgate automotive, to obtain a specific curve of the balancing force as a function of the opening angle which is not a function of the sole characteristic of the balancer.
  • the invention provides a tailgate balancing device for a motor vehicle, said tailgate being articulated to the structure of the vehicle about a horizontal axis, this device comprising at least one balancer, one end of which is linked to the tailgate by a ball joint remote from said axis, and the other end of which is articulated to the structure of the vehicle by means of a bent return lever comprising two unequal arms and articulated by its elbow to the structure of the vehicle around an axis substantially parallel to the axis of articulation of the tailgate, the end of the arm, directed towards the axis, forming an articulation for said other end of the balancer, characterized in that the end of the other arm of this lever is in contact with the concave cam surface of a cam attached to the tailgate.
  • the balancing device intended to equip the tailgate 1 of a vehicle, articulated to the structure of this vehicle around a horizontal axis 2, comprises, in known manner: a balancer 3, which can be a pneumatic cylinder, connected by one of its ends 4 to the tailgate 1 by a ball joint or similar articulation 5, opposite the axis 2, and a return lever 6 of angled shape comprising two arms 7 and 8 of unequal lengths, substantially perpendicular to each other.
  • the other end 9 of the balancer 3 is linked by a ball joint 10 to the end of the arm 8 of said lever 6 which is articulated to it by its elbow around an axis 11, substantially parallel to axis 2, also linked to the structure of the vehicle at 12.
  • the end of the arm 7 of the lever 6 carries a roller 14 which is in contact with the concave surface 15 of a cam 16 fixed to the tailgate 1, the concavity of this cam being directed towards the interior of the tailgate and the arm 8 of the lever 6 being substantially directed towards the axis 2.
  • the weight of the tailgate is shown diagrammatically by the arrow P.
  • the balancer 3 linked to the tailgate 1 by the articulation point 5, develops on the end 10 of the bent return lever 6 a force F i directed along the straight line which joins the axes 5 and 10 of the articulations supporting the balancer 3.
  • FIG. 4 also shows four opening positions of the tailgate 1 (as well as the corresponding positions of the lever 6 and of the cam 16) from 5 ° to 5 ° corresponding to opening angles of the tailgate of 5 °, 10 °, 15 ° and 20 °.
  • Such a representation Sentation makes it easy to understand the principle of developing the profile of the cam surface 15 as a function of the actual final balancing curve that it is desired to obtain. It suffices for each opening angle of the tailgate to geometrically determine the position of the corresponding contact point C so as to obtain the corresponding value of C 2 .
  • the device according to the invention simple and reliable, ensures a better distribution of the energy contained in the balancer (s), and guarantees an automatic opening of the tailgate as soon as the lock of the latter is released.
