Definitions

  • the invention relates to a device for assisting with the operation of an opening leaf articulated on the body of a vehicle automobile.
  • the invention also relates to a use of such a device and to a motor vehicle comprising a such device.
  • an activator formed by a gas spring to assist the opening an opening, such as a tailgate, a rear flap, a trunk door or engine hood.
  • the spring gas is articulated on the vehicle body or on a part secured to it by one of its ends and, by its other end, on the opening considered.
  • US-A-6,041,548 proposes an articulation system comprising an actuator formed by a gas spring and two levers of which only one is bent.
  • the force exerted by the gas spring tends to open the system which is therefore not stable in this configuration. This results in prolonged stresses on the opening, these constraints being all the more important as the spring to gas is powerful, so they can induce opening deformations.
  • the invention relates to a device of the aforementioned type which includes an activator, a first lever articulated by a first end on a support and by a second end on a second lever, itself hinged on a plate, the activator being, meanwhile, articulated on the support and on the second lever, while the support and the plate are respectively secured to the opening and the vehicle body, or vice versa, characterized in that, in the closed position of the sash, the first lever is articulated on the second lever in an overall area aligned with the activator.
  • the use of the two levers allows to evolve, depending on the orientation of the two levers which depends on the position of the sash, the orientation of the activator and the effort it exerts on the opening.
  • the articulated structure formed of the two levers can orient the activator, depending on the degree opening, so that the effort it exerts on this opening is correctly directed.
  • the intense effort generated by the activator in the closed position essentially results in a compressive force exerted on the second lever, this effort being taken up by the first lever. So the opening is not subjected to intense efforts and is not likely to deform.
  • the invention also relates to the use of a device as previously described for assistance with operation of an opening leaf on a motor vehicle, this opening comprising a lateral upright forming an inclined section, from an upper part of the opening, towards another part of the vehicle when the door is closed.
  • the invention finally relates to a motor vehicle equipped of a device as previously described. Use such a vehicle remains easy, especially for opening or the closing of its doors, including when these have a relatively complex form.
  • the motor vehicle V shown in FIGS. 1, 3 and 5 includes a box 1 fitted with doors 2 and a tailgate or rear flap 3.
  • This tailgate is articulated on the body 1 at the hinge level, only one of which is shown with reference 4, defining a pivot axis X-X 'of the tailgate 3 compared to the body 1.
  • the tailgate 3 comprises an upper strip 31 in which are fixed the hinges 4 and a bottom panel 32 possibly forming a reception area for signaling 33.
  • the strip 31 is connected to the panel 32 by lateral uprights, only one of which is visible on the figures with the reference 34.
  • a window 35 is arranged in the opening formed between the elements 31, 32 and 34.
  • the post 34 includes a section 34 a extending in a direction YY 'inclined to the vertical ZZ' when the vehicle V lies on a plane ground.
  • the section 34a extends along the direction Y-Y ', towards the front of the vehicle V from the headband 31.
  • the device 10 for assisting in the opening of the opening leaf 3 is disposed between an upright 11 of the body 1, formed in the vicinity of the opening of the rear trunk, and section 34 a of the upright 34.
  • the device 10 comprises a plate 101 intended to be fixed by screws, represented by their axis lines 102, on the upright 11 which is integral with the box 1.
  • a support 103 is provided to be secured to the section 34 a of the post 34 by means of screws, represented by their axis lines 104.
  • a first lever 105 is articulated on the support 103 by virtue of an axis 106 passing through a first end 105 a of the lever 105 and a tab 103 a of the support 103.
  • the lever 105 is articulated, around an axis 107, on a second lever 108, itself articulated, around an axis 109, on a tab 101 a of the plate 101.
  • a gas spring 110 is installed between the support 103 and the lever 108. More specifically, the spring 110 comprises a cylindrical part 110 a provided with a head 110 b intended to cover a ball joint 103 b secured to the support 103, while one end 110 c of the rod 110 d of the spring 110 covers a ball joint 108 c secured to the lever 108.
  • the first lever 105 is bent, as is the second lever 108.
  • the geometry of the elements 101 to 110 and the location of the elements 101 and 103 are chosen such that, in the closed position of the tailgate 3, a part 108 e of the second lever 108, defined between the zone 108 d and the end 108 b , approximately extends the spring 110. This part 108 e then works essentially in bending / compression while the first lever 105 works essentially in extension between its ends 105 a and 105 b .
  • the angle between the lever 108 and the lever 105 is noted ⁇ .
  • the angle ⁇ is small, which corresponds to the fact that the part 108 e substantially extends the spring 110.
  • the elements 101 to 110 are produced so that this angle is as small as possible. , in particular less than 30 °, preferably less than 20 °, in the position of FIG. 2. Conclusive tests have been carried out with values of ⁇ between 15 and 17 °.
  • the angle ⁇ is not zero in the position of Figure 2 in order to avoid blockage by "knee brace” effect. For the same reason, this angle ⁇ is less than 180 ° in the position in Figure 6.
  • the arm lever 105 relative to axis 109 is substantially equal to the lever arm of the gas spring 110 relative to this axis. This compensates for the effort developed by the spring to gas 110.
  • This force is, in particular, transmitted to the upright 34 and has the effect of displacing the support 103 and the lever 105 to pivot the lever 108 around the axis 109, as shown by the arrow F 3 in FIG. 4.
  • This pivoting induces a displacement of the ends 105 b and 108 b of the levers 105 and 108 in an arc of a circle C while the ball joint 108 c and the end 110 c of the spring 110 are displaced in an arc of a circle C ', concentric with the arc C and centered on the axis 109.
  • This movement of the end 108 b is due to the force transmitted by the end 105 b of the lever 105.
  • the displacement of the lever 108 according to the arrow F 3 has the effect of displacing the gas spring 110 from the position of FIG. 2 to that of FIG. 4 where the direction of the force F 1 has changed with respect to the configuration of Figure 2, this direction being adapted to exert on the tailgate 3 effective assistance to the opening movement.
  • the continuation of the opening movement induces the continuation of the pivoting of the lever 108 around the axis 109, the axis 107 and the ends 105 b and 108 b continuing to move on the arc C while the ball joint 108 c and the end 110 c continue to move on the arc C '.
  • the direction of the force F 1 changes accordingly and remains adapted to the position of the tailgate 3.
  • the articulated structure formed of the levers 105 and 108 makes it possible to orient the gas spring 110 as a function of the degree of opening of the tailgate 3, so that the force F 1 exerted by this spring is permanently correctly oriented by compared to tailgate 3 and body 1.
  • the device of the invention in the closed position of the tailgate 3, is particularly compact and can be housed in a gutter formed by the upright 11 and / or the upright 34 while the first lever 105 effectively compensates for the force F 1 due to the gas spring, which makes it possible to reduce the stresses exerted on the structure of the tailgate 3.
  • the invention makes it possible in particular to use a spring gas while the tailgate 3 includes a window 35 which is largely projecting towards the rear fenders of the vehicle, point that it is arranged in an area where are usually articulated gas springs of known devices.
  • the geometry of the elements 101 to 110 and the intensity of the force F 1 are such that, from a certain degree of opening, for example the position shown in FIGS. 3 and 4, the assistance generated by the device of the invention allows automatic opening of the tailgate 3.
  • the device of the invention also makes it possible to assist the closing movement of the tailgate while preventing it from violently hits the cash register.
  • the invention has been shown with a tailgate of vehicle. It is of course applicable to other types opening, for example a trunk door, a shutter rear or a bonnet.
  • the elements 101 to 110 constituting the device 10 can be made of steel, aluminum, material composite or any other material, depending on requirements retained for the vehicle and the weight of the door.
  • the invention has been shown with a trained activator by a gas spring.
  • Other types of activators can be used, such as an electric, hydraulic or pneumatic or mechanical device with progressive elasticity of the helical spring type.
  • the invention has been shown during its use for a tailgate. It is applicable with any type of opening such as engine hoods, doors or rear trunk doors.
