Definitions
- the invention relates to a vehicle door handle, comprising a handle support and a handle movably mounted on the handle support, the handle being able to assume at least one rest position and a standby position, and the handle, when installed in a vehicle door in the rest position, is flush with the outside of the vehicle door is arranged and arranged in the standby position for actuation in relation to the outside of the vehicle door in an opening direction, a mass balancing element being coupled to the handle and being pivotally mounted on the handle support about a pivot axis, and wherein when the handle is moved from the rest position into the standby position Handle swings the mass balancing element from a basic position into an operating position.
- a vehicle door handle of the type described at the outset is from, for example WO 2016/041996 A1 known.
- a vehicle door handle in which the handle in its rest position is flush with the outside of the vehicle door, is known from the prior art.
- the design of a vehicle door handle according to the invention relates to such constructions in which the handle support is attached to the rear of the vehicle door, ie inside the motor vehicle.
- the handle attached to the handle support usually protrudes from the vehicle door and disturbs both the aesthetic impression of the vehicle and the vehicle aerodynamics.
- vehicle door handles are known from the prior art in which the handle is in its rest position, ie in which it is not is used, runs approximately flush with the outside of the vehicle door, i.e. flush with the surface or flush.
- Such a handle can be brought into a standby position for opening the vehicle door or a vehicle-side lock, in which the handle protrudes from the outside of the vehicle door.
- the handle is extended by a motor when a legitimate operator approaches the vehicle. As soon as the handle is no longer needed, it returns to the rest position and thus disappears in the body so as not to create any air resistance.
- the invention is based on a prior art in which such flush vehicle door handles do not have a crash lock or similar safety elements which are intended to ensure in the event of a vehicle accident that the vehicle door remains closed and is not opened undesirably due to acceleration forces acting on the handle.
- the problem of very low crash safety arises in particular for flush-fitting vehicle door handles when the handle is in different positions, such as in the rest position or the ready position. As a result, there is a risk that, in the case of flush-fitting vehicle door handles, low and unfavorably directed acceleration forces can cause the vehicle door to open.
- the invention has for its object to provide a solution which provides a vehicle door handle in a structurally simple manner, which is inexpensive to manufacture and which moreover has improved safety in the event of a vehicle accident in order to prevent undesired opening of the vehicle door.
- the object is achieved in that the mass balancing element with its mass and / or its geometry is designed to match the handle such that the mass balancing element both in the rest position and in the standby position of the handle under the action of an acceleration force directed in the opening direction, a counter torque acting on the handle and preventing the handle from at least one further movement in the opening direction is generated.
- the mass balancing element holds the handle at least either in the rest position or in the standby position, wherein the mass balancing element can, for example, also cause the handle to move in a direction opposite to the opening direction, i.e.
- the handle in addition to the rest position and the ready position, the handle can also assume an actuating position in which the handle is then moved further out of the ready position in the opening direction by an operator in order to effect a door opening process.
- the invention provides a vehicle door handle which is distinguished by a functionally appropriate construction and has a compact and inexpensive structure.
- a balancing mass in the form of the mass balancing element is kinematically coupled to the handle as an additional component.
- the mass balancing element is also moved by the handle, the kinematics of the mass balancing element being designed in such a way that the mass balancing element has a "closing moment", ie a counter moment, both in the rest position and in the standby position a critical lateral acceleration force acting in the opening direction.
- the invention provides that the mass balancing element has a balancing mass body arranged at a first distance from the pivot axis and a coupling device arranged at a distance from the pivot axis for coupling motion to the handle.
- the mass balancing element can be disc-shaped or designed in the manner of a lever, wherein it is rotatably mounted on the pivot axis and both the coupling device and the balancing mass body are arranged on the mass balancing element at predetermined distances from the pivot axis.
- the first distance is smaller than the second distance.
- the balancing mass body is mounted much closer to the pivot axis than the coupling device, so that a strong acceleration of the mass balancing element in the event of a crash is possible when acceleration forces become effective.
- the invention provides in a further embodiment that the balancing mass body and the coupling device are designed and arranged at different circumferential positions on the mass balancing element with respect to the pivot axis.
- the invention provides a possibility for compact and space-saving design of the mass balancing element in that the mass balancing element is designed as a two-sided lever, which is pivotably mounted on the handle support about the pivot axis, with a first lever arm of the two-sided lever having the coupling device for coupling motion with the handle has and a second lever arm of the two-sided lever has the balancing body.
- the mass balancing element is designed as a two-sided lever, which is pivotably mounted on the handle support about the pivot axis, with a first lever arm of the two-sided lever having the coupling device for coupling motion with the handle has and a second lever arm of the two-sided lever has the balancing body.
- the invention provides that the length of the second lever arm is shorter than the length of the first lever arm.
- the mass balancing element could also be designed as an angle lever.
- the coupling device is designed as a guide recess, in which a movement pin coupled to the handle is arranged, which is movably guided along the guide recess when the handle moves.
- the invention provides in a further embodiment that the guide recess is designed to run radially with respect to the pivot axis.
- the guide recess therefore extends radially towards the pivot axis or radially away from the pivot axis.
- the movement pin is integrally formed on a lever mechanism which is rotatably mounted on the handle support via an axis of rotation and which movably fastens the handle to the handle support, the mass balancing element being coupled in motion with the handle via the handle mechanism. It is particularly advantageous if the lever mechanism is also coupled to a Bowden cable system, so that the mass balancing element can act directly on the component which is responsible for opening the door.
- the movement pin is formed on a lever of the lever mechanism that can be rotated about the axis of rotation, wherein when the handle is moved from the rest position into the ready position of the two-sided lever, a lever lying between the basic position and the operating position Passes through intermediate position in which the two-sided lever is arranged in line with the lever of the lever mechanism.
- the invention provides in an embodiment that the swivel angle between the basic position and the intermediate position is designed symmetrically to the swivel angle between the intermediate position and the operating position. In this way, the narrow installation space conditions and a large swivel path of the handle are taken into account when moving from the rest position to the standby position.
- a vehicle or motor vehicle 1 is shown as an example in the form of a car, which in the example has four vehicle doors 2 (two of which are from Figure 1 can be seen), which has a respective vehicle door handle 3 and in particular with the aid of a handle 4 of the Vehicle door handle 3 can be opened.
- the vehicle doors 2 are firmly closed by means of a respective door lock 5 and can only be opened or unlocked from the outside by a respective movement of the handle 4.
- This movement on the handle 4 consists of a pulling movement, the corresponding movement of the handle 4 being transmitted to the corresponding lock 5 via a Bowden cable system 6.
- the corresponding vehicle door 2 can then be opened by the corresponding movement of the handle 4, a slight pulling movement being sufficient in the case of a current-operated normal operation so that the Bowden cable system 6 is operated electrically for unlocking the door lock 5.
- the vehicle door handle 3 is designed such that a manual unlocking of the door lock 5 and thus a manual opening of the vehicle door 2 by an operator-operated actuation of the handle 4 is possible, which is due to a required, increased actuating force in the Compared to the operating force required in normal operation.
- the Figure 2 shows a perspective view of one of the vehicle doors 2 and the handle 4 used to open the vehicle door 2.
- the handle 4 - when the vehicle door handle 3 is installed in the vehicle door 2 - is arranged approximately flush with the outside 7 of the vehicle door 2, ie flush with the surface or flush with the surface. In this position, the handle 4 is in a rest position, in which it is not used. From the in Figure 2 shown rest position (see also Figures 16 and 17 ) the handle 4 is in a standby position (see Figures 18 and 19 ) transferable, in which it protrudes relative to the outside 7 of the vehicle door 2. Accordingly, the handle 4 is arranged in its ready position protruding from the vehicle door 2.
- the transfer of the handle 4 from the rest position into the standby position can take place either in a current-operated normal operation by means of a suitable drive means or in a currentless emergency operation by means of manual operation by the operator, which is not the subject of the present invention, for which reason it is not closer the mechanism provided for this is discussed.
- proximity sensors or other sensors can be provided in order to bring the handle 4 out of the flush or flush rest position into the ready position as soon as an operator approaches the vehicle door handle 3 or the handle 4.
- the vehicle door handle 3 is shown in different views and for different structural details.
- the vehicle door handle 3 has a handle support 8 which, in the installed state, is fastened on the inside to the vehicle door 2 and serves, among other things, to store the handle 4 in such a way that the handle 4 in its rest position is flush with the outside 7 of the handle Vehicle door 2 is arranged to extend and can be moved into its ready position for actuation, the handle 4 in its ready position protruding from the outside 7 of the vehicle door 2 and can be gripped and actuated by the operator to open the vehicle door 2.
- Figure 3 shows the vehicle door handle 3 in a perspective front view, wherein the handle 4 is in its rest position.
- FIG 4 The rear view shown on the vehicle door handle 3 illustrates the compact construction of the vehicle door handle 3, which takes up little space.
- This compact structure is achieved, inter alia, by a complex lever system 9 (see for example Figures 6 and 7 ) realized, which comprises a lever element 10, a lever mechanism 11 and a movement transmission bracket 12, such as the Item representation in Figure 5 shows.
- the lever element 10, the lever mechanism 11 and the movement transmission bracket 12 are mounted on the handle support 8, the handle 4 being connected to the handle support 8 by means of the lever system 9.
- the vehicle door handle 3 comprises a vehicle door opening lever 14, an actuating element 15 and a mass compensation element 16, which are each also mounted on the handle carrier 8.
- a first longitudinal end 17 of the handle 4 is connected to the handle support 8 via the lever element 10, the lever element 10 being attached to a lever rotation axis 18 rotatably mounted on the handle support 8.
- the lever element 10 which is configured with one arm and is angled, is coupled in motion to the handle 4 when the lever element 10 rotates about the lever axis of rotation 18.
- a second longitudinal end 19 of the handle 4 is connected to the handle support 8 via the lever mechanism 11, the lever mechanism 11 being rotatably mounted on the handle support 8 via an axis of rotation 21, so that the second longitudinal end 19 of the handle 4 is connected to the handle support via the lever mechanism 11 8 is movably attached.
- the lever mechanism 11 comprises a handle lever 20 connected to the handle 4 and a lever body 22 rotatably mounted on an axis of rotation 21 (see for example Figure 8 ).
- the handle lever 20 is formed with one arm and angled and rotatably connected to the second longitudinal end 19 of the handle 4.
- the handle lever 20 is arranged between the two sections of the two-part axis of rotation 21, as a result of which a very compact design can be achieved.
- the handle lever 20 is also rotatably connected to the lever body 22, the lever body 22 having a passive lever 23 and an active lever 24 (see for example Figure 8 ).
- the passive lever 23 and the active lever 24 are mounted on the axis of rotation 21 mounted on the handle support 8 and rotate together when the handle 4 moves from the rest position to the standby position, whereas when the handle 4 is actuated from the ready position, there is a relative movement between the passive lever 23 and the active lever 24.
- the handle lever 20 is rotatably connected to the passive lever 23, wherein the passive lever 23 is rotatably connected to the axis of rotation 21.
- the active lever 24 is rotatably connected to the axis of rotation 21, so that the active lever 24 is rotatably mounted on the axis of rotation 21 thereof.
- lever mechanism 11 What is special about the lever mechanism 11 is the fact that the passive lever 23 and the active lever 24, which form the lever body 22, act as a single lever when the handle 4 moves from the rest position into the ready position and rotate together about the axis of rotation 21, whereas for actuation processes of the handle 4 of the passive lever 23 and the active lever 24 caused by the operator in the ready position, they rotate relative to one another about the axis of rotation 21 and act accordingly as separate levers.
- the lever element 10 is connected in a motion-coupled manner to the lever mechanism 11 via the movement transmission bracket 12 (see for example Figure 6 ).
- a first longitudinal end 25 of the motion transmission bracket 12 is rotatably connected to the lever element 10 at a distance from the lever axis of rotation 18.
- a second longitudinal end 26 of the movement transmission bracket 12 is rotatably connected to the lever mechanism 11 at a distance from the axis of rotation 21.
- the lever element 10, on which the handle 4 is articulated pivots about the lever rotation axis 18, as a result of which the handle 4 is moved from its flush rest position into the ready position and protrudes from the outside 7 of the vehicle door 2.
- the Movement of the movement transmission bracket 12 in the direction of the lever mechanism 11 or in the direction of the second longitudinal end 19 of the handle 4 causes the lever mechanism 11 to rotate about the axis of rotation 21 counterclockwise, which is caused by the movement transmission bracket 12.
- the vehicle door opening lever 14 which is in the form of a rod, is mounted on the handle support 8 so that it can move parallel to the movement transmission bracket 12 via two articulation points 14a, a ground pull lever 14b projecting radially from one of the two articulation points 14a (see Figure 5 ), to which a Bowden cable, not shown in the figures, can be attached, which in turn is connected to the door lock 5 of the vehicle door 2 and is used in a known manner to unlock the door lock 5.
- the lever element 10 and the lever mechanism 11 are out of engagement with the movement transmission bracket 12, so that in the rest position of the handle 4, the lever element 10 and the lever mechanism 11 are from the movement transmission bracket 12 are decoupled.
- the movement transmission bracket 12 In the rest position of the handle 4, the movement transmission bracket 12 is arranged in a position from which it can be moved into an unlocking position in order to unlock the door lock 5.
- the motor-driven adjusting element 15 In the rest position of the handle 4, the motor-driven adjusting element 15 is decoupled from the lever element 10 and the lever mechanism 11 and has no fixed connection to the lever element 10 and the lever mechanism 16. The actuating element 15 is consequently not in engagement with the lever element 10 and with the lever mechanism 11 when the handle 4 is arranged in its rest position.
- the motor-driven control element 15 is mounted on the handle support 8, a motor drive axis of an electric motor driving and rotating the control element 15.
- a vehicle control controller In a current-operated normal operation of the vehicle door handle 3, an approach of an authorized operator to the vehicle 1 is recognized by a vehicle control controller, whereupon a signal is sent by the vehicle control controller to the electric motor, which then starts operating and rotates the actuating element 15 via the motor drive axis.
- the electric motor is energized for a predetermined period of time and rotates the actuating element 15 about the motor drive axis by a predetermined angle which is in a range from 90 ° to 130 °.
- the actuating element 15 is disc-shaped with a non-uniform edge 27 (see for example Figures 9 and 10 ) and rotatably mounted on the handle support 8 via the motor drive axis.
- the non-uniform edge 27 interacts with the lever element 10 in such a way that a rotation of the adjusting element 15 leads to a uniform handle opening movement.
- the motion transmission bracket 12 interacts with the active lever 24 and rotates the active lever 24 about the axis of rotation 21.
- the passive lever 23 and the active lever 24 rotate as the common lever body 22 about the axis of rotation 21.
- the one transmitted by the movement of the motion transmission bracket 12 to the lever mechanism 11 Force causes the handle lever 20 to move away from the axis of rotation 21 due to its coupling with the handle 4, as a result of which the second longitudinal end 19 of the handle 4 is arranged to be exposed from the outside 7 of the vehicle door 2.
- the connection of the second longitudinal end 20 of the handle 4 is consequently designed in the manner of a toggle lever.
- unlocking contour 28 acts upon a movement of the actuating element 15, which is triggered or effected by the operator actuating the handle 4.
- the actuating element 15 is rotated further by actuating the handle 4, as a result of which the unlocking contour 28 moves the vehicle door opening lever 14 in the direction of the lever mechanism 11 urges and thus actuates the Bowden cable system 6 to unlock the door in that the Bowden cable lever 14b is also moved by the movement of the vehicle door opening lever 14.
- a de-energized emergency operation which can occur if the electrical supply to the vehicle 2 fails or if the drive motor fails, the handle 4 can also be pulled so far into the opening direction by the operator's increased force that the lever 11 for the vehicle door opening lever 14 can be pulled manually by the operator moved and thus the Bowden cable system 6 is operated.
- the Figures 11 to 19 show structural details that are in connection with the mass balancing element 16.
- the mass balancing element 16 of the vehicle door handle 3 serves to ensure that the handle 4 both in the rest position and in the standby position when acting in an opening direction 29 (see, for example, arrow in FIG Figure 17 ) directed acceleration force is prevented from moving in the direction of the opening direction 29 by the mass balancing element 16 generating a corresponding counter torque 41.
- the mass balancing element 16 is pivotably mounted on the handle support 8 via a pivot axis 30, the mass balancing element 16 also being coupled to the handle 4.
- the mass balancing element 16 has a balancing mass body 31 and a coupling device 32 for coupling movement to the handle 4, the balancing mass body 31 being arranged at a first distance 33 from the pivot axis 30 on the mass balancing element 16 and the coupling device at a second distance 34 from Pivot axis 30 is arranged on the mass balancing element 16.
- the first distance 33 is formed smaller than the second distance 34.
- the representation in Figure 12 It can be seen that the balancing mass body 31 and the coupling device 32 with respect to the pivot axis 30 at different circumferential positions on the Mass balancing element 16 are formed and arranged.
- the mass balancing element 16 is designed as a two-sided lever 35.
- This two-sided lever 35 is pivotably mounted on the handle support 8 about the pivot axis 30, a first lever arm 35a of the two-sided lever 35 having the coupling device 32 for coupling movement to the handle 4 and a second lever arm 35b of the two-sided lever 35 having the balancing mass body 31 , Accordingly, the length 36 of the second lever arm 35b is shorter than the length 37 of the first lever arm 35a.
- the coupling device 32 is formed on the first lever arm 35a as a guide recess 38.
- the guide recess 38 serves for the fact that in it a movement pin 39 coupled to the handle 4 (see for example Figures 8 and 11 ) is arranged, the movement pin 39 being movably guided along the guide recess 38 when the handle 4 is moved.
- the movement pin 39 is integrally formed on the lever mechanism 11 which is rotatably mounted on the handle support 8 via the axis of rotation 21 and which movably fastens the handle 4 on the handle support 8. Consequently, the mass balancing element 16 is coupled in motion to the handle 4 via the lever mechanism 11.
- the movement pin 39 is formed on a lever 40 of the lever mechanism 11 which can be rotated about the axis of rotation 21, wherein existing levers of the lever mechanism 11 with corresponding modification / adaptation could also be used for this purpose.
- the guide recess 38 is designed to run radially with respect to the pivot axis 30.
- the mass balancing element 16 is thus motion-coupled to the handle 4 and, depending on the position of the handle 4, assumes a corresponding position (basic position, operating position).
- the two-sided lever 35 passes through the intermediate position lying between the basic position and the operating position (see Figure 14 ).
- the mass balancing element 16 designed as a two-sided lever 35 is arranged in line with the lever 40 of the lever mechanism 11.
- the swivel angle 42a between the basic position and the intermediate position is designed symmetrically to the swivel angle 42b between the intermediate position and the operating position, as schematically in FIG Figure 14 is shown.
- the mass balancing element 16 is designed with its mass and geometry matched to the handle 4 in such a way that the mass balancing element 16 both in the rest position and in the ready position of the handle 4 under the action of an acceleration force directed in the opening direction 29, as occurs, for example, in the event of a vehicle accident. one acting on the handle 4 and the handle 4 at least a further movement in the opening direction 29 prevents counter torque 41.
- the counter torque 41 acts counterclockwise in the Figures 13, 14 and 15 , so that the lever 40 is held by the influence of the counter torque 41 at least in its position shown in the figures or from the position shown in FIGS Figures 14 and 15 positions shown back in the Figure 13 position shown (by rotating lever 40 clockwise with respect to FIG Figure 15 ) is moved, in which the handle 4 is arranged in its rest position.
- the mass balancing element 16 prevents a further movement of the handle 4 in the opening direction 29.
- the present invention relates to a vehicle door handle 3 which has the handle support 8 and the handle 4 movably mounted on the handle support 8.
- the handle 4 can at least assume the rest position and the standby position, but can also be moved beyond the standby position when actuated by an operator.
- the handle 4 When installed in a vehicle door 2 in the rest position, the handle 4 is arranged flush with the outside 7 of the vehicle door 2 and in the ready position for actuation relative to the outside 7 of the vehicle door 2 arranged in the opening direction.

Die an dem Griffträger angebrachte Handhabe steht bei solchen Ausführungsformen üblicherweise von der Fahrzeugtür hervor und stört sowohl den ästhetischen Eindruck des Fahrzeugs als auch die Fahrzeug-Aerodynamik. Um diese Nachteile zu vermeiden, sind daher aus dem Stand der Technik Fahrzeugtürgriffen bekannt, bei denen die Handhabe in ihrer Ruhestellung, d.h. in welcher sie nicht gebraucht wird, in etwa bündig zur Außenseite der Fahrzeugtür, also strakbündig bzw. flächenbündig, verläuft. Eine solche Handhabe ist zum Öffnen der Fahrzeugtür oder eines fahrzeugseitigen Schlosses in eine Bereitschaftsstellung überführbar, in welcher die Handhabe gegenüber der Außenseite der Fahrzeugtür vorsteht. Dabei wird die Handhabe motorisch ausgefahren, wenn sich ein legitimierter Bediener dem Fahrzeug nähert. Sobald die Handhabe nicht mehr gebraucht wird, fährt sie wieder in die Ruhestellung und verschwindet somit in der Karosserie, um keinen Luftwiderstand zu erzeugen.A vehicle door handle, in which the handle in its rest position is flush with the outside of the vehicle door, is known from the prior art. There are a variety of different designs and embodiments for such known vehicle door handles. The design of a vehicle door handle according to the invention relates to such constructions in which the handle support is attached to the rear of the vehicle door, ie inside the motor vehicle. In such embodiments, the handle attached to the handle support usually protrudes from the vehicle door and disturbs both the aesthetic impression of the vehicle and the vehicle aerodynamics. In order to avoid these disadvantages, vehicle door handles are known from the prior art in which the handle is in its rest position, ie in which it is not is used, runs approximately flush with the outside of the vehicle door, i.e. flush with the surface or flush. Such a handle can be brought into a standby position for opening the vehicle door or a vehicle-side lock, in which the handle protrudes from the outside of the vehicle door. The handle is extended by a motor when a legitimate operator approaches the vehicle. As soon as the handle is no longer needed, it returns to the rest position and thus disappears in the body so as not to create any air resistance.
Die Erfindung geht von einem Stand der Technik aus, bei dem solche flächenbündigen Fahrzeugtürgriffe keine Crashsperre oder ähnliche Sicherheitselemente aufweisen, die im Fall eines Fahrzeugunfalls sicherstellen sollen, dass die Fahrzeugtür geschlossen bleibt und nicht unerwünscht aufgrund von an der Handhabe angreifenden Beschleunigungskräften geöffnet wird. Dabei ergibt sich insbesondere für flächenbündige Fahrzeugtürgriffe das Problem einer sehr geringen Crashsicherheit, wenn sich die Handhabe in unterschiedlichen Stellungen, wie zum Beispiel in der Ruhestellung oder der Bereitschaftsstellung, befindet. Folglich besteht die Gefahr, dass bei flächenbündigen Fahrzeugtürgriffen geringe und ungünstig gerichtete Beschleunigungskräfte ein Öffnen der Fahrzeugtür bewirken können.The invention is based on a prior art in which such flush vehicle door handles do not have a crash lock or similar safety elements which are intended to ensure in the event of a vehicle accident that the vehicle door remains closed and is not opened undesirably due to acceleration forces acting on the handle. The problem of very low crash safety arises in particular for flush-fitting vehicle door handles when the handle is in different positions, such as in the rest position or the ready position. As a result, there is a risk that, in the case of flush-fitting vehicle door handles, low and unfavorably directed acceleration forces can cause the vehicle door to open.
Der Erfindung liegt die Aufgabe zugrunde eine Lösung zu schaffen, die auf konstruktiv einfache Weise einen Fahrzeugtürgriff bereitstellt, der kostengünstig in seiner Herstellung ist und der darüber hinaus eine verbesserte Sicherheit im Fall eines Fahrzeugunfalls aufweist, um ein unerwünschtes Öffnen der Fahrzeugtür zu verhindern.The invention has for its object to provide a solution which provides a vehicle door handle in a structurally simple manner, which is inexpensive to manufacture and which moreover has improved safety in the event of a vehicle accident in order to prevent undesired opening of the vehicle door.
Bei einem Fahrzeugtürgriff der eingangs genannten Art wird die Aufgabe dadurch gelöst, dass das Massenausgleichselement mit seiner Masse und/oder seiner Geometrie derart auf die Handhabe abgestimmt ausgebildet ist, dass das Massenausgleichselement sowohl in Ruhestellung als auch in Bereitschaftsstellung der Handhabe bei Einwirkung einer in die Ausstellrichtung gerichteten Beschleunigungskraft ein auf die Handhabe wirkendes und die Handhabe zumindest an einer weiteren Bewegung in Ausstellrichtung hinderndes Gegenmoment erzeugt. Erfindungsgemäß hält das Massenausgleichselement die Handhabe zumindest entweder in der Ruhestellung oder in der Bereitschaftsstellung, wobei das Massenausgleichselement zum Beispiel auch eine Bewegung der Handhabe in eine der Ausstellrichtung entgegengesetzte Richtung, also in Richtung der Ruhestellung, bewirken kann, wenn sich die Handhabe in der Bereitschaftsstellung befindet. Erfindungsgemäß kann die Handhabe neben der Ruhestellung und der Bereitschaftsstellung auch eine Betätigungsstellung einnehmen, bei welcher die Handhabe dann von einem Bediener aus der Bereitschaftsstellung heraus weiter in Ausstellrichtung bewegt wird, um einen Türöffnungsvorgang zu bewirken.In the case of a vehicle door handle of the type mentioned at the outset, the object is achieved in that the mass balancing element with its mass and / or its geometry is designed to match the handle such that the mass balancing element both in the rest position and in the standby position of the handle under the action of an acceleration force directed in the opening direction, a counter torque acting on the handle and preventing the handle from at least one further movement in the opening direction is generated. According to the invention, the mass balancing element holds the handle at least either in the rest position or in the standby position, wherein the mass balancing element can, for example, also cause the handle to move in a direction opposite to the opening direction, i.e. in the direction of the rest position, when the handle is in the standby position , According to the invention, in addition to the rest position and the ready position, the handle can also assume an actuating position in which the handle is then moved further out of the ready position in the opening direction by an operator in order to effect a door opening process.
Vorteilhafte und zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous and expedient refinements and developments of the invention result from the subclaims.
Durch die Erfindung wird ein Fahrzeugtürgriff zur Verfügung gestellt, der sich durch eine funktionsgerechte Konstruktion auszeichnet und einen kompakten und kostengünstigen Aufbau aufweist. Bei dem Fahrzeugtürgriff gemäß der Erfindung wird eine Ausgleichsmasse in Form des Massenausgleichselements als zusätzliches Bauteil an die Handhabe kinematisch angekoppelt. Während der Bewegung der Handhabe aus der Ruhestellung in die Bereitschaftsstellung wird das Massenausgleichselement von der Handhabe mitbewegt, wobei die Kinematik des Massenausgleichselements derart gestaltet ist, dass das Massenausgleichselement sowohl in der Ruhestellung als auch in der Bereitschaftsstellung ein "schließendes Moment", d.h. ein Gegenmoment bei einer kritischen lateralen in Ausstellrichtung wirkenden Beschleunigungskraft erzeugt.The invention provides a vehicle door handle which is distinguished by a functionally appropriate construction and has a compact and inexpensive structure. In the vehicle door handle according to the invention, a balancing mass in the form of the mass balancing element is kinematically coupled to the handle as an additional component. During the movement of the handle from the rest position to the standby position, the mass balancing element is also moved by the handle, the kinematics of the mass balancing element being designed in such a way that the mass balancing element has a "closing moment", ie a counter moment, both in the rest position and in the standby position a critical lateral acceleration force acting in the opening direction.
Die Erfindung sieht in Ausgestaltung vor, dass das Massenausgleichselement einen mit einem ersten Abstand zur Schwenkachse angeordneten Ausgleichsmasse-Körper und eine mit einem zweiten Abstand zur Schwenkachse beabstandet angeordnete Kopplungseinrichtung zur Bewegungskopplung mit der Handhabe aufweist. Das Massenausgleichselement kann dabei scheibenförmig oder nach Art eines Hebels ausgebildete sein, wobei es an der Schwenkachse drehbar gelagert ist und sowohl die Kopplungseinrichtung als auch der Ausgleichsmasse-Körper in vorbestimmten Abständen zur Schwenkachse an dem Massenausgleichselement angeordnet ausgebildet sind.In one embodiment, the invention provides that the mass balancing element has a balancing mass body arranged at a first distance from the pivot axis and a coupling device arranged at a distance from the pivot axis for coupling motion to the handle. The mass balancing element can be disc-shaped or designed in the manner of a lever, wherein it is rotatably mounted on the pivot axis and both the coupling device and the balancing mass body are arranged on the mass balancing element at predetermined distances from the pivot axis.
Zur Einhaltung der engen Bauraumbedingungen ist es in Ausgestaltung der Erfindung von Vorteil, wenn der erste Abstand kleiner ist als der zweite Abstand. Auf diese Weise ist der Ausgleichsmasse-Körper wesentlich näher an der Schwenkachse gelagert als die Kopplungseinrichtung, so dass eine starke Beschleunigung des Massenausgleichselements im Crashfall bei wirksam werdenden Beschleunigungskräften möglich ist.To maintain the narrow installation space conditions, it is advantageous in an embodiment of the invention if the first distance is smaller than the second distance. In this way, the balancing mass body is mounted much closer to the pivot axis than the coupling device, so that a strong acceleration of the mass balancing element in the event of a crash is possible when acceleration forces become effective.
Unter Berücksichtigung der engen Bauraumbedingungen sieht die Erfindung in weiterer Ausgestaltung vor, dass der Ausgleichsmasse-Körper und die Kopplungseinrichtung mit Bezug auf die Schwenkachse an unterschiedlichen Umfangspositionen an dem Massenausgleichselement ausgebildet und angeordnet sind.Taking into account the narrow installation space conditions, the invention provides in a further embodiment that the balancing mass body and the coupling device are designed and arranged at different circumferential positions on the mass balancing element with respect to the pivot axis.
Eine Möglichkeit zur kompakten und platzsparenden Ausbildung des Massenausgleichselements sieht die Erfindung in Ausgestaltung dadurch vor, dass das Massenausgleichselement als ein zweiseitiger Hebel ausgebildet ist, welcher um die Schwenkachse schwenkbar an dem Griffträger gelagert ist, wobei ein erster Hebelarm des zweiseitigen Hebels die Kopplungseinrichtung zur Bewegungskopplung mit der Handhabe aufweist und ein zweiter Hebelarm des zweiseitigen Hebels den Ausgleichsmasse-Körper aufweist. Im Hinblick auf eine starke Beschleunigung des Massenausgleichselements, die im Crashfall bei in Ausstellrichtung wirkenden Beschleunigungskräften erwünscht ist, sieht die Erfindung vor, dass die Länge des zweiten Hebelarms kürzer ausgebildet ist als die Länge des ersten Hebelarms. Alternativ zur Ausgestaltung eines zweiseitigen Hebels könnte das Massenausgleichselement auch als ein Winkelhebel ausgebildet sein.In one embodiment, the invention provides a possibility for compact and space-saving design of the mass balancing element in that the mass balancing element is designed as a two-sided lever, which is pivotably mounted on the handle support about the pivot axis, with a first lever arm of the two-sided lever having the coupling device for coupling motion with the handle has and a second lever arm of the two-sided lever has the balancing body. With regard to a strong acceleration of the mass balancing element, which in the event of a crash with acceleration forces acting in the opening direction is desired, the invention provides that the length of the second lever arm is shorter than the length of the first lever arm. As an alternative to the configuration of a two-sided lever, the mass balancing element could also be designed as an angle lever.
Konstruktiv besonders günstig ist es in weiterer Ausgestaltung der Erfindung, wenn die Kopplungseinrichtung als eine Führungsausnehmung ausgebildet ist, in welcher ein mit der Handhabe gekoppelter Bewegungszapfen angeordnet ist, der bei einer Bewegung der Handhabe entlang der Führungsausnehmung bewegbar geführt ist.In a further embodiment of the invention, it is structurally particularly advantageous if the coupling device is designed as a guide recess, in which a movement pin coupled to the handle is arranged, which is movably guided along the guide recess when the handle moves.
Damit das Massenausgleichselement von der Handhabe mitbewegt werden kann und bei der Mitbewegung kein erhöhter Widerstand erzeugt wird, sieht die Erfindung in weiterer Ausgestaltung vor, dass die Führungsausnehmung mit Bezug auf die Schwenkachse radial verlaufend ausgebildet ist. Die Führungsausnehmung erstreckt sich also radial zur Schwenkachse hin bzw. radial von der Schwenkachse weg.In order that the mass balancing element can also be moved by the handle and that no increased resistance is generated when the handle is moved, the invention provides in a further embodiment that the guide recess is designed to run radially with respect to the pivot axis. The guide recess therefore extends radially towards the pivot axis or radially away from the pivot axis.
In einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass der Bewegungszapfen an einer über eine Drehachse drehbar an dem Griffträger gelagerten Hebelmechanik angeformt ist, welche die Handhabe an dem Griffträger bewegbar befestigt, wobei das Massenausgleichselement über die Hebelmechanik mit der Handhabe bewegungsgekoppelt ist. Besonders günstig ist es dabei, wenn die Hebelmechanik ferner mit einem Bowdenzugsystem gekoppelt ist, so dass das Massenausgleichselement direkt an dem Bauteil wirksam werden kann, welches für eine Öffnung der Tür verantwortlich ist.In a further embodiment of the invention it is provided that the movement pin is integrally formed on a lever mechanism which is rotatably mounted on the handle support via an axis of rotation and which movably fastens the handle to the handle support, the mass balancing element being coupled in motion with the handle via the handle mechanism. It is particularly advantageous if the lever mechanism is also coupled to a Bowden cable system, so that the mass balancing element can act directly on the component which is responsible for opening the door.
Konstruktiv und kinematisch von Vorteil ist es in Ausgestaltung der Erfindung, wenn der Bewegungszapfen an einem um die Drehachse drehbaren Hebel der Hebelmechanik ausgebildet ist, wobei bei einer Bewegung der Handhabe aus der Ruhestellung in die Bereitschaftsstellung der zweiseitige Hebel eine zwischen der Grundposition und der Betriebsposition liegende Zwischenposition durchläuft, in welcher der zweiseitige Hebel in Linie zu dem Hebel der Hebelmechanik angeordnet ist.It is constructively and kinematically advantageous in an embodiment of the invention if the movement pin is formed on a lever of the lever mechanism that can be rotated about the axis of rotation, wherein when the handle is moved from the rest position into the ready position of the two-sided lever, a lever lying between the basic position and the operating position Passes through intermediate position in which the two-sided lever is arranged in line with the lever of the lever mechanism.
Schließlich sieht die Erfindung in Ausgestaltung vor, dass der Schwenkwinkel zwischen der Grundposition und der Zwischenposition zu dem Schwenkwinkel zwischen der Zwischenposition und der Betriebsposition symmetrisch ausgeführt ist. Auf diese Weise wird den engen Bauraumbedingungen und einem großen Schwenkweg der Handhabe bei ihrer Bewegung aus der Ruhestellung in die Bereitschaftsstellung Rechnung getragen.Finally, the invention provides in an embodiment that the swivel angle between the basic position and the intermediate position is designed symmetrically to the swivel angle between the intermediate position and the operating position. In this way, the narrow installation space conditions and a large swivel path of the handle are taken into account when moving from the rest position to the standby position.

Der Rahmen der Erfindung ist nur durch die Ansprüche definiert.It goes without saying that the features mentioned above and still to be explained below can be used not only in the respectively specified combination but also in other combinations or on their own without departing from the scope of the present invention.

Die Hebelmechanik 11 umfasst einen mit der Handhabe 4 verbundenen Griffhebel 20 und einen drehbar an einer Drehachse 21 gelagerten Hebelkörper 22 (siehe zum Beispiel
Das Hebelelement 10 ist über den Bewegungsübertragungsbügel 12 mit der Hebelmechanik 11 bewegungsgekoppelt verbunden (siehe zum Beispiel
Wenn die Handhabe 4 von einem Bediener aus der Bereitschaftsstellung heraus betätigt wird, ist dies eine Ziehbewegung an der Handhabe 4, wodurch diese in eine Betriebsstellung gelangt. In einer solchen Betriebsstellung ist das Hebelelement 10 weiterhin in der Position angeordnet, in welcher es in der Bereitschaftsstellung angelangt war. Es findet folglich keine weitere Drehung um die Hebeldrehachse 18 statt. Vielmehr erfolgt an der Hebelmechanik 11 eine Relativbewegung zwischen dem Passivhebel 23 und dem Aktivhebel 24, wobei dazu der Bediener eine entsprechende Kraft bei seiner Ziehbewegung an der Handhabe 4 aufbringen muss. Durch die Krafteinwirkung des Bedieners über die Handhabe 4 wird der Passivhebel 23 relativ zu dem Aktivhebel 24 bewegt, wobei der Aktivhebel 24 in seiner Position verbleibt, die er in der Bereitschaftsstellung der Handhabe 4 bereits eingenommen hat.If the
Der Fahrzeugtüröffnungshebel 14, der stangenförmig ausgebildet ist, ist über zwei Gelenkpunkte 14a an dem Griffträger 8 parallel bewegbar zu dem Bewegungsübertragungsbügel 12 gelagert, wobei von einem der beiden Gelenkpunkte 14a radial ein Bodenzughebel 14b absteht (siehe
Das motorangetriebene Stellelement 15 ist in der Ruhestellung der Handhabe 4 von dem Hebelelement 10 und der Hebelmechanik 11 entkoppelt und weist keine feste Verbindung zu dem Hebelelement 10 und der Hebelmechanik 16 auf. Das Stellelement 15 steht folglich mit dem Hebelelement 10 und mit der Hebelmechanik 11 nicht in Eingriff, wenn die Handhabe 4 in ihrer Ruhestellung angeordnet ist. Das motorangetriebene Stellelement 15 ist an dem Griffträger 8 gelagert, wobei eine Motorantriebsachse eines Elektromotors das Stellelement 15 antreibt und dreht. In einem strombetriebenen Normalbetrieb des Fahrzeugtürgriffs 3 wird von einer Fahrzeugkontrollsteuerung eine Annäherung eines berechtigten Bedieners an das Fahrzeug 1 erkannt, woraufhin ein Signal von der Fahrzeugkontrollsteuerung an den Elektromotor gesandt wird, der daraufhin seinen Betrieb aufnimmt und über die Motorantriebsachse das Stellelement 15 dreht. Dabei wird der Elektromotor für eine vorbestimmte Zeitdauer bestromt und dreht das Stellelement 15 um die Motorantriebsachse um einen vorbestimmten Winkel, der in einem Bereich von 90° bis 130° liegt. Das Stellelement 15 ist scheibenförmig mit einem ungleichförmigen Rand 27 ausgebildet (siehe zum Beispiel
Der Bewegungsübertragungsbügel 12 wirkt mit dem Aktivhebel 24 zusammen und dreht den Aktivhebel 24 um die Drehachse 21. Dabei drehen der Passivhebel 23 und der Aktivhebel 24 als der gemeinsamer Hebelkörper 22 um die Drehachse 21. Die durch die Bewegung des Bewegungsübertragungsbügels 12 auf die Hebelmechanik 11 übertragene Kraft bewirkt, dass sich der Griffhebel 20 aufgrund seiner Kopplung mit der Handhabe 4 von der Drehachse 21 wegbewegt, wodurch das zweite Längsende 19 der Handhabe 4 aus der Außenseite 7 der Fahrzeugtür 2 ausgestellt angeordnet ist. Die Anbindung des zweiten Längsendes 20 der Handhabe 4 ist folglich nach Art eines Kniehebels ausgebildet.The
Bei der vorstehend beschriebenen Bewegung des Stellelements 27 wird lediglich die Handhabe 4 in die Bereitschaftsstellung bewegt, wohingegen der Fahrzeugöffnungshebel 14 nach wie unbewegt verbleibt. Dies ist auf eine Entriegelungskontur 28 (siehe zum Beispiel

Zusammenfassend betrifft die vorliegende Erfindung einen Fahrzeugtürgriff 3, der den Griffträger 8 und die an dem Griffträger 8 bewegbar gelagerte Handhabe 4 aufweist. Dabei kann die Handhabe 4 zumindest die Ruhestellung und die Bereitschaftsstellung einnehmen, aber auch über die Bereitschaftsstellung hinaus bei Betätigung durch einen Bediener bewegt werden. Die Handhabe 4 ist bei Einbau in eine Fahrzeugtür 2 in Ruhestellung strakbündig mit der Außenseite 7 der Fahrzeugtür 2 verlaufend angeordnet und in Bereitschaftsstellung zur Betätigung gegenüber der Außenseite 7 der Fahrzeugtür 2 in Ausstellrichtung ausgestellt angeordnet. Erfindungsgemäß ist das Massenausgleichselement 16 vorgesehen, welches mit der Handhabe 4 gekoppelt ist und am Griffträger 8 um eine Schwenkachse 30 schwenkbar gelagert ist. Bei Bewegung der Handhabe 4 aus der Ruhestellung in die Bereitschaftsstellung schwenkt die Handhabe 4 das Massenausgleichselement 16 aus der Grundposition in die Betriebsposition. Das Massenausgleichselement 16 ist mit seiner Masse und/oder seiner Geometrie derart auf die Handhabe 4 abgestimmt ausgebildet, dass das Massenausgleichselement 16 sowohl in Ruhestellung als auch in Bereitschaftsstellung der Handhabe 4 bei Einwirkung einer in die Ausstellrichtung 29 gerichteten Beschleunigungskraft das auf die Handhabe 4 wirkende und die Handhabe 4 zumindest an einer weiteren Bewegung in Ausstellrichtung 29 hindernde Gegenmoment 41 erzeugt.In summary, the present invention relates to a
