Definitions

  • the present invention relates to a device opening a sash with a horizontal axis, in particular a tailgate of a motor vehicle, as well as an equipped opening of such an opening device.
  • Openings with horizontal axis are equipped with less of a displacement member which assists the tilting of the opening between a closed position and a position opening.
  • This displacement member is constituted by example by a torsion bar integrated into the joint or by a gas spring with rectilinear action.
  • the resistance of active efforts must be generated by the displacement member, always greater than or at least equal to the sum of the passive forces due to the mass of the opening and the various frictions.
  • the opening does not remain stable in its maximum opening position, but it tends to descend to the position where the forces balance, i.e. in an intermediate open position substantially horizontal.
  • the invention aims to obtain an opening device which overcomes the disadvantages of the state of the art and which facilitates the gripping of a sash with a horizontal axis to toggle it between an open position and a closed position.
  • the subject of the invention is therefore a device opening a sash with a horizontal axis, in particular a tailgate of a motor vehicle, of the type comprising at least a member for moving the opening between a position of closing and a maximum opening position, characterized in that it comprises at least two magnetic elements in opposite, one of the two elements being mounted on the horizontal axis and the other of said elements being connected to a part fixed and moving magnetic elements one by relation to the other determinant, on the one hand, a force of braking when opening the door between the position of closing and an intermediate position located before the position maximum opening and, on the other hand, several positions opening stop stable between this position intermediate opening and said opening position Max.
  • the subject of the invention is also an opening to horizontal axis formed by a tailgate provided with an opening device as previously mentioned.
  • the subject of the invention is also a motor vehicle, characterized in that it comprises at least one opening as previously mentioned.
  • FIG 1 there is shown schematically the rear part of a motor vehicle, for example minivan or mono sedan type generally designated by reference 1.
  • the motor vehicle 1 has a body delimiting a passenger compartment 2 containing a driving position and several rows of seats, not shown.
  • the passenger compartment 2 is delimited, inter alia, by a floor 3, a pavilion 4 and, at its rear, by an opening with a horizontal axis 5 of the tailgate type.
  • the opening 5 has, in its upper part, articulation means on the roof 4 and which are formed by a horizontal axis 6 so that the opening 5 can be moved between a closed position A of the game rear of passenger compartment 2 and an open position B maximum, by angular displacement around the horizontal axis 6, giving access to the rear part of said passenger compartment 2 '.
  • the opening 5 is movable between these two positions A and B by an arrangement, not shown, of direct acting springs, like for example a torsion bar integrated into the joint or at least one gas spring with rectilinear action.
  • the lever arm l 2 In a substantially horizontal position C, the lever arm l 2 is maximum so that the torque determined by the weight P of the opening 5 and said lever arm l 2 is also maximum.
  • the opening device comprises at least two elements magnetic opposite, one of the elements being mounted on the horizontal axis and the other of said elements being connected to a fixed part and the displacement of magnetic elements one with respect to the other determinant, on the one hand, a braking force when opening sash 5 between position A closing and an intermediate opening position D located before position B of maximum opening and, on the other hand, several stable positions for stopping the sash 5 between this intermediate opening position D and said position B of maximum opening.
  • the two magnetic elements placed in opposite generate a zone of amplitude L (Figure 1) where all the intermediate positions of the opening 5 are stable, this opening can remain immobilized whatever his position.
  • the amplitude zone L represents substantially a displacement of 60 °.
  • the magnetic elements include two annular magnets, respectively 10 and 20, with magnetization axial, each formed by a flat ring.
  • one end of the horizontal axis 6 supporting the opening 5 has a journalled bearing 11 on pads 12 having flanges axial support.
  • the bearing 12 integral in rotation with the axis horizontal 6 supports a plate 13 on which is fixed a soft iron cylinder head 14 receiving the annular element 10 having the shape of a flat ring.
  • a fixed part 8 of the framework of the vehicle supports a plate 21 forming a bearing fixed and on which is mounted a soft iron cylinder head 22 receiving the annular magnet 20 with axial magnetization and constituted by a flat ring.
  • the magnets 10 and 20 are arranged in vis-a-vis.
  • the annular magnet 10 comprises a succession of north and south poles equally distributed over the circumference and the magnet 20 also includes a succession of north poles and south equally distributed over the circumference, as shown in Figure 3.
  • Each annular magnet 10 and 20 is made of a material anisotropic with strong remanent magnetization, as by example a ceramic based on barium ferrite or strontium or an alloy made from rare earths, for example samarium-cobalt or neodymium-iron-boron.
  • the two magnets 10 and 20 antagonists being identical, the poles of opposite names attract very strongly and find as many stable positions as there are pairs of poles.
  • the brake effect between the closed position A and intermediate position D is not not continuous, but made up of a series of notches closer together that the number of poles is high. Enter here position D intermediate and position B maximum opening, the opposing magnets 10 and 20 determine several stable sash stop positions 5.
  • the magnetic elements include an annular element 30 carried by the plate 13 integral with the horizontal axis 6 and produced in one soft magnetic material with weak coercive field, such as example an isotropic metal alloy.
  • Magnetic elements also include an annular magnet 40 with magnetization axial fixed on the cylinder head 22 in soft iron which is carried by the plate 21 fixed on the fixed part 8.
  • the element annular 30 and the annular magnet 4 are arranged in opposite and each formed by a flat ring.
  • the annular magnet 40 includes a succession of north and south poles also distributed around its circumference.
  • This magnet 40 is made in an anisotropic magnetic material having a strong remanent magnetization, for example a ceramic with base of barium ferrite or strontium or an elaborate alloy from rare earths, like samarium-cobalt or again neodymium-iron-boron.
  • the annular element 30 is only magnetized by the influence and proximity of the annular magnet 40 which prints its poles in its material. So the relative rotation annular element 30 and annular magnet 40 made that each particle of this annular element 30, successively magnetized then demagnetized, goes through magnetized states of opposite polarity by describing a hysteresis cycle which involves an energy expenditure and which results in a strong resistance to movement.
  • the annular element 30 and the annular magnet 40 determine a braking force at the opening of the opening 5 between the closed position A and the position D intermediate opening and, on the other hand, several positions stopping stable of this opening 5 between position D opening position and position B of maximum opening.
  • the horizontal axis 6 comprises at one of its ends, a bearing 51 journalling on bearings 52 provided with axial support flanges.
  • a tray 53 forming a soft iron cylinder head is mounted integral in rotation with the bearing 51 and, therefore, with the axis horizontal 6.
  • the plate 53 supports an annular magnet 50 with radial magnetization.
  • On a fixed part 8 is fixed a plate 61 forming a soft iron cylinder head which supports the fixed bearing 51 and which receives an annular magnet 60 with magnetization radial.
  • the annular magnet 60 is concentric with the annular magnet 50 and located substantially in the same plan.
  • the annular magnets 50 and 60 are made of a material anisotropic with strong remanent magnetization, capable of pass through a relatively intense reverse magnetic field without undergoing demagnetization.
  • This material is for example a ceramic based on barium ferrite or strontium or an alloy made from rare earths, such as samarium-cobalt or neodymium-iron-boron.
  • the ring magnets 50 and 60 include a succession of north poles and south equally distributed over the circumference of each of these magnets.
  • the angular distribution of the poles of the two magnets antagonists 50 and 60 being the same, the name poles otherwise attract very strongly and find as many stable angular positions that there are pairs of poles.
  • the brake effect is not continuous, but consists of a series of notches the closer together the higher the number of poles.
  • the magnetic elements include an annular magnet 70 with radial magnetization supported by the plate 53 integral in rotation with the horizontal axis 6 via the bearing 51.
  • the annular magnet 70 includes a succession of north and south poles equally distributed over its circumference.
  • this annular magnet 70 is made of an anisotropic material with low remanent magnetization, for example a ceramic based on barium ferrite or strontium or an alloy made from rare earths, like for example samarium-cobalt or neodymium-iron-boron.
  • the magnetic elements also include a annular element 80 supported by the plate 61 integral with the fixed part 8.
  • This annular element 80 is produced in a soft magnetic material with a low coercive field, such as for example an isotropic metal alloy.
  • the annular magnet 70 and the annular element 80 are concentric and each formed by a cylinder.
  • the annular element 80 is only magnetized by the influence and proximity of the annular magnet 70 which prints its poles in its material.
  • the relative rotation of the annular magnet 70 and the annular element 80 means that each particle of the annular element 80, successively magnetized then demagnetized, goes through magnetized states of opposite polarity by describing a hysteresis cycle which involves an energy expenditure and which leads to strong resistance At the move.
  • the efforts resistors keep a constant value whatever the direction and extent of displacement.
  • Curve F represents the decreasing characteristic movement of the opening member 5 necessary to ensure complete opening and maintenance open of said opening 5. It can therefore be seen that at the start of the opening operation, the displacement member exerts an excess of effort S1 which makes the start of the movement brutal opening of this opening 5.
  • the opening device allows the installation of a displacement member constituted by example by a torsion bar or a gas actuator with action rectilinear, which presents an excess of limited force.
  • the opening device according to the invention allows to obtain a terminal zone of the movement opening where the sash remains stable in all positions in this area.
  • This area is defined to correspond to easy grip positions of the sash where it is desirable to stop the sash at will, especially when the ceiling height is limited. This opportunity offers also for users of modest size, ease of gripping to carry out the closing closing operation.
  • the opening device creates an effect contactless brake, therefore without wear and without variation in time.
