Definitions

  • the invention relates to a movement assembly for a door handle assembly.
  • Door handle arrangements with a recessed door handle, in particular for vehicles, in particular for vehicle doors, are generally known from the prior art.
  • the door handle driven by an electric motor, is extended from a position that is lowered into the vehicle door into a position for use. After opening the vehicle door, the door handle is moved back into the lowered position by an electric motor.
  • the object of the present invention is to specify a movement arrangement for a door handle arrangement which is improved compared to the prior art.
  • a door handle arrangement in particular an outside door handle arrangement, is provided for a door, in particular for a vehicle door. It includes a door handle that can be moved from a retracted position into a usage position.
  • the door handle is moved, for example, electrically, in particular by means of an electric motor.
  • the door can be opened by operating and/or touching the door handle. In normal operation, this occurs after the door handle is placed in the use position. i.e. the door handle is first sunk out of the position, in particular in the door, into the position, in particular out the door extended, usage position moves in which it is easily accessible for actuation and / or touch.
  • an emergency release can also be provided for emergency operation, for example in the event of a failure of the electrical power supply or due to another cause, so that the door handle can no longer be moved into the usage position.
  • the door handle can also be actuated and/or touched in the retracted position to open the door.
  • the door handle arrangement also includes a return spring, in particular for returning the door handle from the use position to the retracted position or at least to support this return.
  • the return spring is coupled to the door handle, for example directly to the door handle or via a connecting lever connected to the door handle, and in the retracted position and in the use position to a counter bearing which is at least then fixed, for example directly or via a spring tensioning lever.
  • one spring limb or at least one spring limb of the return spring is coupled to the door handle or to the connecting lever, in particular rests against it
  • the other spring limb or at least one other spring limb of the return spring is coupled with the counter bearing or with the spring tensioning lever, in particular rests against in particular in such a way that the restoring spring is increasingly tensioned or would be tensioned by a relative movement of the connecting lever and spring tensioning lever in one direction and is increasingly relaxed or would be relaxed in the other direction.
  • the restoring spring is used in particular for a coupling, in particular an elastic coupling, of the connecting lever and spring tensioning lever and thus a coupling, in particular an elastic coupling, of the door handle and spring tensioning lever, for example to enable anti-trap protection, in particular during movement into the retracted position.
  • the return spring is decoupled from the abutment between the retracted position and the use position and/or the abutment assumes a retracted abutment position in the retracted position and an extended abutment position in the use position and is out during the movement of the door handle from the retracted position to the use position the retracted counter-bearing position can be converted into the extended counter-bearing position, it then advantageously covering a movement path, for example the same movement path, in the same time as the door handle and/or, if present, its connecting lever.
  • the spring tensioning lever on which the return spring rests and thus also the return spring, is decoupled from the counter bearing between the retracted position and the use position, the spring tensioning lever advantageously being moved with the door handle and thus with the return spring.
  • the drive in particular the electric motor
  • the drive has a larger power reserve and/or it can
  • a smaller drive in particular an electric motor
  • the return spring would be additionally tensioned with each movement of the door handle into the use position, causing unnecessary losses in the drive and increasing wear on the drive and the return spring, thus shortening service life.
  • the solution described avoids this, reduces wear and increases the service life.
  • the door handle assembly includes a spring tensioning lever and an eccentric unit.
  • the return spring is coupled to a spring contact area of the spring tensioning lever.
  • the eccentric unit is rotatably mounted and has a spring tensioning lever eccentric curve for guiding the spring tensioning lever.
  • the spring tensioning lever eccentric cam is designed in such a way that the spring tensioning lever rests against the spring tensioning lever eccentric curve in the retracted position of the door handle and in the use position of the door handle and is spaced from the spring tensioning lever eccentric curve in between.
  • the eccentric unit forms the counter bearing for the restoring spring, which is coupled to the eccentric unit via the spring tensioning lever in the retracted position and the use position.
  • the eccentric unit is arranged on a component of the door handle arrangement, for example on a bearing bracket, which is stationary, at least stationary when the door handle is in the retracted position and in the usage position.
  • the door handle arrangement is fastened or can be fastened to the door via this bearing bracket.
  • the restoring spring is part of a movement arrangement, in particular for moving the door handle from the retracted position to the usage position and back.
  • This movement arrangement comprises the connecting lever coupled, in particular pivotably coupled, to the door handle, in particular to an end region of the door handle, the spring tensioning lever, the restoring spring and the eccentric unit.
  • the eccentric unit forms the abutment for the restoring spring, which is coupled to the eccentric unit via the spring tensioning lever in the retracted position and the use position.
  • the eccentric unit is arranged on a component of the door handle arrangement, for example on the bearing bracket, which is stationary, at least stationary when the door handle is in the retracted position and in the usage position. The door handle arrangement is fastened or can be fastened to the door via this bearing bracket.
  • the connecting lever and the spring tensioning lever are advantageously mounted pivotably about a common pivot axis and pivotable relative to one another about this pivot axis.
  • the restoring spring is advantageously coupled to a spring contact area of the connecting lever and to the spring contact area of the spring tensioning lever, in particular with a spring leg in each case, such that it can be relaxed by a pivoting movement of the spring contact area of the spring tensioning lever in the direction of the spring contact area of the connecting lever and can be tensioned by an opposite pivoting movement.
  • the return spring is coupled in the retracted position and the use position via the spring tensioning lever to the eccentric unit that forms the counter bearing, so that the spring tensioning lever is then immovable and thus, for example, also keeps the connecting lever and thus also the door handle immovable due to the pretension of the return spring .
  • this prevents the door handle from rattling, for example.
  • the eccentric unit is rotatably mounted, for example rotatably mounted on the bearing bracket, and advantageously has a connecting lever eccentric curve for guiding the connecting lever and the spring tensioning lever eccentric curve for guiding the spring tensioning lever.
  • These eccentric cams are advantageously arranged in two different planes, so that the eccentric unit has two eccentric disks which are arranged one above the other and are fixed to one another or designed in one piece, each with one of the eccentric cams.
  • the connecting lever can thus be pivoted about the pivot axis from a connecting lever initial position (retracted position of the moving arrangement) into a connecting lever end position (extended position of the moving arrangement) by means of the connecting lever eccentric cam.
  • the spring tensioning lever is located in the retracted position of the movement arrangement in a tensioning lever initial position, the spring contact areas of the spring tensioning lever and connecting lever advantageously being spaced apart from one another in such a way that the return spring is pretensioned, i.e. slightly tensioned, in particular in such a way that it lies firmly against the two spring contact areas and therefore does not rattle.
  • the spring tensioning lever In the extended position of the movement arrangement, the spring tensioning lever is in a tensioning lever end position, the spring contact areas of the spring tensioning lever and connecting lever advantageously being spaced apart again in such a way that the return spring is pretensioned, i.e. slightly tensioned, in particular in such a way that it rests firmly on the two spring contact areas and therefore not rattling.
  • the spring clamping lever In the clamping lever initial position and clamping lever end position, the spring clamping lever is in contact with the spring clamping lever eccentric curve. In between, i.e.
  • the spring clamping lever is at a distance from the spring clamping lever eccentric curve, i.e. it no longer rests against it and can therefore freely move around the Swivel swivel axis. Due to the previously prestressed return spring between the spring tensioning lever and the connecting lever, the spring contact area of the spring tensioning lever approaches the spring contact area of the connecting lever while the return spring relaxes and is then pivoted together with the connecting lever and the return spring due to the connection via the return spring.
  • the eccentric unit and/or the pivot axis are arranged on the bearing bracket and are therefore immovable components, with the exception of the rotation of the eccentric unit, i. H. the eccentric unit itself is in a fixed position, it only rotates, in particular on a drive axle which is arranged in the bearing bracket, so that the eccentric cams move accordingly.
  • the eccentric unit thus forms the counter bearing for the return spring. Spring tensioning lever and connecting lever move by pivoting around the pivot axis.
  • the eccentric unit is advantageously arranged fixedly on the drive axle or is designed in one piece with it and can be rotated by rotating the drive axle.
  • the door handle is thus driven to move it into the usage position via the eccentric unit.
  • the eccentric unit is advantageously arranged on the bearing bracket via the drive axle, which is rotatably mounted in the bearing bracket. As already mentioned, it is thus arranged in a fixed position on the bearing bracket and thus forms the counter bearing for the return spring. The position of the counter bearing is changed by turning the eccentric unit, whereby the spring tensioning lever rests against different areas of the spring tensioning lever eccentric curve.
  • the movement arrangement in particular the connecting lever, is advantageously coupled to a further movement arrangement which is coupled to the other end region of the door handle, in particular is pivotably coupled.
  • both end regions of the door handle can be moved by means of a single drive unit, so that the door handle can be moved from the retracted position into the use position, for example by a parallel displacement.
  • a force transmission rod is advantageously arranged between the movement arrangement, in particular its connecting lever, and the further movement arrangement.
  • the door handle arrangement advantageously comprises such a movement arrangement as already described above.
  • the connecting lever eccentric cam is advantageously designed in such a way that the connecting lever rests against a first connecting lever contact section in the retracted position and against a second connecting lever contact section of the connecting lever eccentric cam in the extended position, with the first connecting lever contact section being at a smaller distance from the drive axis than the second connecting lever contact section, with the first connecting lever contact section has the smallest distance between the connecting lever eccentric cam and the drive axle, and the second connecting lever contact section has the greatest distance between the connecting lever eccentric cam and the drive axle.
  • the spring tensioning lever eccentric cam is advantageously designed such that the spring tensioning lever rests in the retracted position on a first spring tensioning lever contact section and in the extended position on a second spring tensioning lever contact section of the spring tensioning lever eccentric curve.
  • the first spring tensioning lever contact section is at a greater distance from the drive axle than the second spring tensioning lever contact section, with the first spring tensioning lever contact section having the greatest distance between the spring tensioning lever eccentric cam and the drive axle, and the second connecting lever contact section having the smallest distance between the spring tensioning lever eccentric curve and the drive axle. This ensures that the spring tensioning lever eccentric cam rests against the spring tensioning lever pivoted along with the connecting lever in the tensioning lever end position.
  • the first spring tensioning lever contact section of the spring tensioning lever eccentric curve forms the abutment for the spring tensioning lever and thus for the return spring, with the abutment thus being in the retracted abutment position, and in the tensioning lever end position, i.e.
  • the spring tensioning lever has a recess for the passage of the first spring tensioning lever contact section during the rotary movement of the eccentric unit.
  • the connecting lever has, for example, a roller for rolling on the connecting lever eccentric curve of the eccentric unit. This enables the connecting lever and thus the door handle to be moved with little friction and little wear, so that only a small amount of force is required for the drive unit and a long service life is achieved.
  • an electric motor is advantageously provided as the drive unit for rotating the eccentric unit. This enables the door handle to be moved electrically into the use position and back.
  • the eccentric unit is advantageously arranged in a fixed manner on the drive axle or is formed in one piece with it and can be rotated by rotating the drive axle.
  • the drive axle is then advantageously coupled to the electric motor, in particular via a gear, in particular via a worm gear, crown gear, bevel gear or gear transmission. This enables, for example, a force deflection and/or a step-up or step-down.
  • the Figures 1 to 7 show a movement assembly 1 for a door handle assembly 2 and FIG figures 8 and 9 the door handle arrangement 2 with such a movement arrangement 1.
  • the movement arrangement 1 is in figure 1 in a retracted position, in figure 2 in an intermediate position and in figure 3 shown in an extended position.
  • the Figures 4 to 7 show another representation of the movement arrangement 1, which is also shown here in figure 4 in the retracted position, in figure 5 in an intermediate position, in figure 6 in another intermediate position and in figure 7 shown in the deployed position.
  • the door handle assembly 2 is in figure 8 shown in a lowered position, in which the movement arrangement 1 is in the retracted position, and in figure 9 shown in a use position in which the movement assembly 1 is in the extended position.
  • the door handle arrangement 2 is designed in particular as an outside door handle arrangement. It is intended for a door, in particular for a vehicle door. It includes a door handle 3 that can be moved from the retracted position into the usage position. The door handle 3 is moved, for example, electrically, in particular by means of an electric motor, not shown here.
  • the door can be opened by actuating and/or touching the door handle 3 .
  • this takes place after the door handle 3 is arranged in the usage position. i.e. the door handle 3 is first moved from the recessed position, in particular in the door recessed position, into the usage position, in particular extended out of the door, in which it is easily accessible for actuation and/or touching.
  • an emergency release can also be provided for emergency operation, for example in the event of a failure of the electrical power supply or due to another cause, so that the door handle 3 can no longer be moved into the usage position.
  • the door handle 3 can also be actuated and/or touched in the retracted position to open the door.

  • the return spring 4 serves in particular for a coupling, in particular an elastic coupling, of the connecting lever 5 and the spring tensioning lever 6 and thus a coupling in particular an elastic coupling of the door handle 3 and the spring tensioning lever 6, for example in order to enable anti-trap protection, in particular during movement into the retracted position.
  • the return spring 4 is used in particular to carry the door handle 3, more precisely the connecting lever 5 and thus the door handle 3, while it is being moved back into the retracted position.
  • the spring tensioning lever 6 is moved and, due to the spring tension of the return spring 4, takes with it the door handle 3 coupled via the return spring 4 to the spring tensioning lever 6, more precisely the connecting lever 5 coupled via the return spring 4 to the spring tensioning lever 6 and thus also the door handle 3 .
