Description

[0001] The invention relates to a door handle arrangement, in particular an external door handle arrangement, and a vehicle door with such a door handle arrangement.

[0002] Door handle arrangements for vehicle doors are known, for example, from DE 10 2015 115 673 A1. Vehicle doors typically include an outer door handle which is mechanically or electrically coupled to a locking mechanism. For example, actuation of the door handle moves the locking mechanism from a locked position to an unlocked position, thus allowing the vehicle door to be opened. The vehicle door includes, for example, a door handle in which an outer gripping surface is positioned approximately flush with an outer door surface of an outer vehicle door wall when the door handle is in a rest or non-use position. By means of an adjustment mechanism, the door handle can be moved outwards into an operating or use position so that it is accessible to a user.

[0003] The object of the present invention is to provide an improved door handle arrangement that enables secure guidance when moving a handle element into a working position or back into a non-working position. Furthermore, it is an object of the invention to provide a vehicle door with an improved door handle arrangement.

[0004] The problem is solved according to the invention with a door handle arrangement having the features of claim 1. With regard to the vehicle door, the problem is solved according to the invention by the features of claim 14.

[0005] Further developments of the invention are the subject of the dependent claims. A door handle arrangement according to the invention comprises at least one support element and a handle element, which is movably arranged on the support element between a non-use position and a use position, as well as an adjustment mechanism for adjusting the handle element relative to the support element, wherein the adjustment mechanism comprises at least one lever and a cam carrier with at least one main cam for controlled movement of the handle element between the non-use position and the use position, and wherein the main cam interacts with a counter surface arranged on the lever and has a variable cam profile, in particular a variable cam pitch.

[0006] Such a door handle arrangement with a main cam featuring a variable cam profile, particularly a variable cam pitch, enables force-optimized adjustment of the handle element between the non-use and use positions. The advantages achievable with the invention lie particularly in the fact that, by means of such a variable cam profile, for example, several cam sections with different cam profiles and correspondingly different adjustment forces are possible during an adjustment movement of the handle element. For example, releasing or adjusting the handle element in various states, such as when the handle is iced over, during extension, and / or in one of the end positions, can be facilitated accordingly.In particular, the cam sections can be designed such that a large part of the required adjusting force, especially a force from a motor or hand operation, is applied for a small handle stroke at the beginning of an opening movement of the handle element, in order to use this large force to, for example, release an iced-up handle element.

[0007] For example, the main cam has at least two cam sections with different cam profiles, in particular slopes. In one possible embodiment, a first cam section has a lower slope than a second cam section. A slope is understood to be the increase in cam radius per angle of rotation. A third cam section has essentially a constant slope. In other words, the third cam section has an approximately constant cam radius per angle of rotation of the cam.

[0008] In one possible embodiment, the first cam section has a first cam profile, in particular a first slope curve, such that the main cam and the lever are spaced apart from each other in the non-use position, in particular at a small distance, for example, the size of an air gap. When the handle element is moved into the use position, the main cam and the lever engage with each other to control the extension movement of the handle element. In the use position, the main cam and the lever are in a blocking or locking engagement, so that the handle element is locked in the use position. This first cam section engages, in particular a frictional engagement, with the mating surface on the lever when the handle element is moved into or is in the use position.

[0009] This first cam section, in particular this first curve, is designed such that the force required to release the handle from its unused position can be overcome when the cam is moved in the opening direction. Furthermore, the first curve can be designed to also overcome the force required to release an iced-up handle. Additionally, the cam can have a cam offset that serves as an end stop. In the unused position of the handle, one end face of the lever rests against the cam offset.

[0010] The first cam section, for example, has a particularly short and shallow slope. For instance, the cam radius doubles over a 180° rotation of the cam in the first cam section. The first cam section is designed such that a rotation of the main cam within a first rotation angle range of 160° to 200°, particularly 180°, causes a first opening or closing movement of the handle element within an adjustment range of 4 mm to 7 mm, particularly 5.5 mm.

[0011] In a further embodiment, the second cam section has a curve profile, in particular a long and steep slope, such that the main cam and the lever are movable relative to each other in order to position the handle element in the operating position. For example, the cam radius triples or quadruples over a rotation angle of 180° of the cam in the second cam section. The second cam section can, for example, be designed such that a rotation or pivoting of the main cam in a second rotation angle range of 160° to 200°, in particular by 180°, causes a second opening movement of the handle element in a range of 25 mm to 30 mm, in particular 27.5 mm.

[0012] In a further embodiment, the third cam section has a curve profile, in particular a largely constant or very shallow slope, such that the main cam and the lever engage in a blocking engagement in the operating position. This third cam section engages in a blocking or locking engagement, in particular a frictional engagement, with the mating surface on the lever when the handle element is in the operating position. This third cam section is designed such that the force required to release this engagement can be overcome when the cam is moved in the closing direction. Depending on the type and design of the drive, particularly in the case of a motor drive, the cam section can be designed such that the handle element cannot be pushed into the non-operating position by hand.

[0013] Another aspect is that the cam carrier comprises several main cams that are designed to correspond with each other. This enables a reliable adjustment movement. Each main cam can be designed as a disc or a roller.

[0014] Alternatively or additionally, the adjustment mechanism can couple the handle element and the support element together, wherein the adjustment mechanism, the handle element and the support element are designed and are operatively connected or stand together in the operating position of the handle element in such a way that the handle element is fixed in the operating position or is held without play.

[0015] The advantages gained from this locking mechanism for the handle in its operating position lie particularly in the fact that locking or preventing play in the handle's operating position, especially its extended position where a user grips the handle to open the vehicle door, enables a robust door handle assembly. In particular, such a door handle assembly with a locked, especially pre-tensioned, handle in its operating position allows for a quiet and secure position of the handle in its operating position, as well as improved tactile feedback for the user.

[0016] The handle element can be electrically or mechanically movable. For an electrical extension movement of the handle element, a drive device, for example a motor, is provided, which interacts with the positioning mechanism to move and position the handle element from the non-use position to the use position or vice versa during operation of the drive device.

[0017] Another embodiment provides that the handle element is arranged on the support element in a translationally movable manner, in particular parallel to the vehicle door, or rotationally movable.

[0018] Furthermore, the adjustment mechanism can include an actuating arrangement. For example, the lever allows the handle element to be moved between its unused and working positions relative to the support element. The lever and the actuating arrangement hold the handle element securely in its working position, particularly by clamping it. This ensures that the handle element is held firmly in its working position and, in particular, free of play. Such an adjustment mechanism is robust and simple in design. Moreover, such an adjustment mechanism allows for simple optional variations, such as a stepped gear, especially a single-stage worm gear, a drive symmetry with two drive cams, a variable cam pitch, a direct drive, and functions such as a handle element that can extend both translationally and rotationally.Furthermore, such a door handle arrangement is designed to optimize installation space, particularly in the Y-direction of a coordinate system. This coordinate system comprises a vertical axis Z, which runs parallel to the vehicle's vertical orientation, a longitudinal axis X, which runs parallel to the vehicle's longitudinal orientation, and a transverse axis Y, which runs parallel to the vehicle's transverse orientation.

[0019] Another aspect of the design is that the adjustment mechanism includes a main axis by which the lever is movably mounted on the support element and relative to it. Furthermore, the adjustment mechanism includes a secondary axis by which the handle element is movably mounted on the lever and relative to it. This two-axis adjustment mechanism ensures safe extension and retraction of the handle element. Additionally, the handle element and the support element have corresponding end stops for the operating position. This combination of a two-axis adjustment mechanism with corresponding end stops in the operating position stabilizes the handle element's end position on the support element. The actuating arrangement, particularly a cam arrangement, also clamps the end stops, and thus the handle element, to the support element without play and locks it in the operating position.

[0020] A further aspect of the invention provides that the adjusting arrangement comprises at least one handle support element positioned between the handle and the lever. The handle support element is, for example, designed as a spring element, in particular a leaf spring. The handle support element is positioned between the handle bracket and the lever such that the handle is held under tension both in the retracted or unused position and in the extended or used position. This keeps the handle largely quiet. In particular, during an adjustment movement of the handle from the unused position to the used position or vice versa, the handle is held under tension between the handle bracket and the lever by means of the handle support element, in particular tensioned against the support element, and in particular resiliently supported against the support element.In the non-use position, a space, in particular a gap, is formed between an internal handle part, in particular an internal handle bracket, and the support element.

[0021] Furthermore, in another embodiment, the adjusting mechanism, in particular the adjusting arrangement, comprises the cam carrier with an associated cam axis to guide the handle element between the non-use position and the use position in a controlled manner.

[0022] In a further embodiment, the cam carrier comprises at least the main cam arranged on the cam carrier for the controlled movement of the handle element between the non-use position and the use position. The main cam is, for example, designed as a disk with a curved or arc-shaped projection, in particular a cam disk. When the handle element is adjusted, a rotary movement of the adjusting assembly about the cam axis, and thus a rotary movement of the main cam, is converted into a translational movement, in particular a translational extension or retraction movement, of the handle element. The curved or arc-shaped projection of the at least one main cam has, for example, a variable pitch. This enables the door handle assembly to absorb mechanical forces greater than 250 N when the handle element is actuated, such as those that can occur, for example, when opening an iced-up door handle.

[0023] Additionally, the adjustment mechanism can include at least one auxiliary cam arranged on the cam carrier for controlling the retraction movement of the handle element from the operating position to the non-operating position and / or for decoupling a return spring assembly for the handle element. Such an auxiliary cam for controlling the retraction movement and / or spring decoupling allows the drive device, in particular a motor, to be smaller. Furthermore, such an auxiliary cam for spring decoupling makes the door handle assembly less prone to wear and quieter.

[0024] The lever has at least one cam guide in or on which the cam carrier is guided when the handle element is adjusted between the non-use position and the use position. For example, the cam guide is designed as a guide groove or a guide slot.

[0025] Furthermore, the support element can include at least one handle guide in or on which the handle element is guided when adjusted between the non-use position and the use position. For example, the handle guide is designed as a cam guide. In particular, the handle guide is configured such that the handle element is movable translationally and, in particular, parallel to the vehicle's outer skin. Specifically, the handle guide has a cam, in particular a sliding or guide, form such that possible manufacturing and / or assembly deviations, especially angular deviations, are compensated for.

[0026] The door handle assembly can also include additional functional units, such as actuator electronics, for example with a Hall sensor for controlled extension of the handle element and activation of the drive mechanism; a mechanical emergency operation, for example in the form of a mechanical push button and locking cylinder; handle electronics, for example with near- and / or far-range sensors to detect a user's approach; and handle illumination, for example recessed lighting and / or external lighting. The handle element can also include components of a keyless entry system, for example a capacitive sensor on the outside for locking and on the inside for unlocking. The capacitive sensor (also called M(etal)O(ver)C(apacity)) reacts to changes in distance to a protective element and serves to generate an opening / unlocking signal.

[0027] Alternatively or in addition to the electrically operated door handle assembly, it can also be operated manually. For this purpose, the door handle assembly additionally or alternatively includes a manual switching element, for example, a slider or a push button. When the switching element is actuated, the handle element moves from the inactive position to the operating position due to a motion coupling between the switching element and the actuator. To trigger or open the door lock, the handle element can alternatively be moved, for example, by a vertical movement if it is not fully extended.

[0028] A vehicle door is equipped with at least one door handle assembly, as described above. In particular, the door handle assembly is designed as an external door handle assembly. The door handle assembly has a compact, especially compact in the Y-direction, wear-resistant, and cost-effective design.

[0030] Corresponding parts are marked with the same reference symbols in all figures.

[0031] Fig. Figure 1 shows a schematic perspective view of a vehicle door 1 with a door handle arrangement 2. The door handle arrangement 2 is designed as an external door handle arrangement.

[0032] The door handle assembly 2 comprises a handle element 3, in particular an outer door handle. The handle element 3 can be mechanically or electrically coupled to a locking mechanism for a door lock (not shown). For example, actuation of the handle element 3 moves the locking mechanism from a locked position to an unlocked position to allow the vehicle door 1 to be opened.

[0033] The handle element 3, in particular an outer handle surface of the handle element 3, is positioned approximately flush with an outer door surface of an outer vehicle door wall when the handle element 3 is in a non-use position P1, as shown in Fig. 1 shown. In other words: In the non-use position P1, the handle element 3 is arranged in a recess in the vehicle door 2, in particular recessed, such that the door handle 3 complements an outer contour of the vehicle door 2, in particular is flush with it.

[0034] Fig. Figure 2 shows schematically in perspective the vehicle door 1 with the door handle arrangement 2 with the handle element 3 in a usage position P2.

[0035] The handle element 3 can be moved from the non-use position P1 to the use position P2 opposite and relative to the vehicle door 1, in particular it can be extended. In this use position P2, the handle element 3 can be operated by a user.

[0036] Fig. Figure 3 schematically shows in top view an embodiment of the door handle arrangement 2 with the handle element 3 in the non-use position P1.

[0037] The door handle assembly 2 comprises a support element 4. The handle element 3 is movably arranged on the support element 4. The support element 4 can be made of one piece or multiple parts.

[0038] In the illustrated embodiment, the support element 4 comprises a first support part 4.1 and a second support part 4.2. The first support part 4.1 is, for example, formed as a flat surface. The first support part 4.1 is, in particular, attached to an inner door side 1.1 (in Fig. 4 shown), for example, an inside of an outer door wall, the vehicle door 1 in the area of ​​an opening 1.2 (in Fig. (4 shown) for the handle element 3. The first support part 4.1 has a handle opening 4.1.1 corresponding to an outer contour of the handle element 3, in which the handle element 3 is arranged in the non-use position P1 or through which the handle element 3 is extended when it is moved into the use position P2.

[0039] The second support element 4.2 serves to movably mount the handle element 3 on the support element 4. The second support element 4.2 can also be arranged and attached to the inside of the vehicle door 1. If the vehicle door 1 is double-walled, the door handle assembly 1, in particular the support element 4, is arranged and held in a space between an outer door wall and an inner door wall of the vehicle door 1. The first support element 4.1 can be arranged and attached to the outer door wall. The second support element 4.2 can be arranged and attached to the inner door wall or an inner door panel.

[0040] Fig. Figure 4 schematically shows in side view the door handle arrangement 1 with the handle element 3 in the non-use position P1. The door handle arrangement 2 is arranged on the inside of the door 1.1 such that the handle element 3 is flush with an outside of the door 1.3 in the opening 1.2.

[0041] The first support element 4.1 is formed flat. The second support element 4.2 is partially formed flat and lies largely flush against an inner surface of the first support element 4.1. The second support element 4.2 has a base element 4.2.1 to which the handle element 3 is movably attached.

[0042] The door handle arrangement 1 also includes an adjustment mechanism 5 which couples the handle element 3 and the support element 4 together, in particular in terms of movement.

[0043] Furthermore, the second support element 4.2 can have a circumferential edge 4.2.2, at least partially or completely. The circumferential edge 4.2.2 serves to partially, for example at least laterally, or completely circumferentially cover the internal adjustment mechanism 5.

[0044] The adjustment mechanism 5 comprises at least one lever 6 and one cam carrier 9 for controlled movement of the handle element 3 between the non-use position P1 and the use position P2.

[0045] The adjustment mechanism 5, the handle element 3 and the support element 4 can be designed in such a way and in the operating position P2 (shown in Fig. 5) of the handle element 3 are in such a way that the handle element 3 is additionally secured in this operating position P2, in particular is held without play.

[0046] Fig. Figure 5 schematically shows in side view the door handle arrangement 1 with the handle element 3 in the operating position P2 and without the side cover, in particular without the edge 4.2.2 and in partial sectional view of the adjustment mechanism 5.

[0047] The adjustment mechanism 5 comprises at least one lever 6 by means of which the handle element 3 can be moved relative to the support element 4 between the non-use position P1 and the use position P2. Furthermore, the door handle assembly 1, in particular the adjustment mechanism 5, comprises an actuating arrangement 7 (shown in detail in Fig. 6A to 6C), by means of which the handle element 3 is fixed at least in the operating position P2, in particular held in tension against the lever 6.

[0048] The handle element 3 can be electrically or mechanically movable. For an electrical extension movement of the handle element 3, a drive device 8 is provided, which interacts with the adjusting mechanism 5, in particular a cam carrier 9, and the positioning arrangement 7, in particular the lever 6, to move and position the handle element 3 from the non-use position P1 to the use position P2 or vice versa during operation of the drive device 8. The drive device 8 comprises at least a motor 8.1, a gearbox 8.2, and a housing 8.3. The motor 8.1 is designed as a worm gear motor and comprises a worm shaft 8.4, which engages with a worm wheel 8.5 of the gearbox 8.2 and thus drives it, the axes of the worm shaft 8.4 and the worm wheel 8.5 being arranged at right angles to each other.

[0049] The cam carrier 9 is designed as a camshaft and has a cam axis NA. The axis of the worm gear 8.5 corresponds to the cam axis NA of the cam carrier 9 of the adjusting arrangement 7. The cam carrier 9 is designed in the form of a transmission rod, a bearing pin, or a shaft.

[0050] The drive device 8, the actuating arrangement 7 with the lever 6, the adjusting mechanism 5 with the cam carrier 9, and the support element 4 interact when the handle element 3 is adjusted such that this handle element 3 is movable translationally, in particular parallel to and relative to the vehicle door 1, between the non-use position P1 and the use position P2, and in particular can be extended or retracted. For this purpose, the worm shaft 8.4 drives the worm wheel 8.5, which in turn drives the cam carrier 9, which is rotationally fixed to the driven worm wheel 8.5, and thus also rotates. The drive device 8 is held to the second support part 4.2 by means of a positive or non-positive locking connection. For example, the drive device 8 is held to the second support part 4.2 by means of screw connections 8.6 and / or detent connections 8.7.

[0051] Additionally, the handle element 3 can include handle electronics 3.6, for example with near- and / or far-range sensors for detecting a user's approach, handle lighting (e.g., recessed lighting and / or external lighting). The handle element 3, as handle electronics 3.6, can also include components of a keyless entry system, for example, a capacitive sensor on the outside for locking and on the inside for unlocking.

[0052] On the cam carrier 9 there is at least one main cam 9.1 (shown in Fig. 6A and 11, 11A to 11C) for the controlled movement of the handle element 3 between the non-use position P1 and the use position P2, as detailed in the Fig. is described in sections 11A to 11C.

[0053] To adjust the handle element 3, a rotary movement DB of the adjusting mechanism 5, in particular of the cam carrier 9, about the cam axis NA and of the adjusting arrangement 7, in particular of the lever 6, about the main axis HA, generated by means of the motor 8.1, and thus a rotary movement of the main cam 9.1, is converted into a translational movement TB, in particular into a translational extension or retraction movement, of the handle element 3.

[0054] The door handle arrangement 1 may also include further optional functional units.

[0055] In the exemplary embodiment according to Fig. 4 and Fig. 5 The door handle assembly includes a mechanical emergency operating unit 10. The emergency operating unit 10 comprises one or more manual operating elements 10.1, 10.2, which is / are designed, for example, as an externally accessible rotatable switching disc or ring, flap and / or sliding element.

[0056] The mechanical emergency actuation unit 10 is described below using the Fig. Sections 16 to 18 are described in more detail.

[0057] Fig. Figures 6A to 6C schematically show a sectional view of the door handle arrangement 1 in the area of ​​the adjustment mechanism 5 and the positioning arrangement 7 with different positions P1 to P3 of the handle element 3.

[0058] Fig. Figure 6A shows the handle element 3 in the non-use position P1. In the non-use position P1, a free space FR, in particular a gap, is formed between an internal handle part, in particular an internal handle bracket 3.2, the handle bracket arms 3.2.2, and the support element 4, in particular the second support element 4.2.

[0059] The lever 6 comprises at least two axes. A first lever axis is a main axis HA of the adjusting mechanism 5. By means of a pivot bearing 11, for example a bearing pin, the lever 6 is mounted on the support element 4 and relative to it in a manner movable about the main axis HA, in particular pivotable or rotatable.

[0060] Furthermore, the adjustment mechanism 5 includes a secondary axis HiA about which the handle element 3 is movably, in particular rotatably, mounted on the lever 6 and relative to it. For this purpose, a further pivot bearing 11, in particular a bearing pin, is arranged on the secondary axis HiA. The pivot bearings 11 are arranged and held on the support element 4.

[0061] Such a two-axis adjustment mechanism 5 enables a safe extension and retraction movement of the handle element 3.

[0062] Additionally, the lever 6 includes a projection 6.1 extending towards the handle element 3, which is designed and shaped such that the handle element 3 is supported and / or secured, in particular pre-tensioned, in the non-use position P1. For example, the projection 6.1 includes a handle stop surface 6.1.1.

[0063] Furthermore, a handle support element 7.1 is provided, which is arranged between the handle 3, in particular the handle bracket 3.2, and the lever 6, for example by clamping or clamping. For example, one end of the handle support element 7.1 is fixed to the handle bracket 3.2 at a stop 3.2.3. An opposite end of the handle support element 7.1 is, for example, positively and / or frictionally secured to the lever 6, in particular in a detent groove 6.7.

[0064] The handle support element 7.1 is designed, for example, as a spring element, in particular a leaf spring or clamp spring. Fig. Figure 6A shows the handle support element 7.1 in a relaxed position.

[0065] In this process, the projection 6.1 abuts a flat rear surface of the handle element 3 in the non-use position P1 and supports the handle element 3.

[0066] The lever 6 further comprises at least one cam guide 6.2 in or on which the cam carrier 9 is guided when the handle element 3 is adjusted between the non-use position P1 and the use position P2. For example, the cam guide 6.2 is designed as a guide groove or a guide slot in which the cam carrier 9.1 is positively guided.

[0067] The handle element 3 comprises an outer grip surface 3.1 and at least one handle bar 3.2. In particular, two handle bars 3.2 are provided, which are spaced apart from each other on the rear side of the grip surface 3.1, in particular arranged parallel to each other, and extend inwards from the grip surface. In the area behind the grip surface 3.1 and to the side of the at least one handle bar 3.2, or behind the grip surface 3.1 and between the two handle bars 3.2, a grip recess 3.3 for a user's hand is formed when the handle element 3 is in the operating position P2 (see Fig. 6C).

[0068] The pivot bearing 11 of the secondary axis HiA is arranged on the handle 3.2. The handle 3.2 has a guide or sliding element 3.2.1, in particular a sliding rib or edge, which is guided, in particular positively guided, on a handle guide 4.3 of the support element 4 when the handle element 3 is adjusted between the non-use position P1 and the use position P2. For example, the handle guide 4.3 is designed as a cam guide. The handle guide 4.3 has, in particular, a cam, in particular sliding, or guide shape such that possible manufacturing and / or assembly deviations, in particular angular deviations, are compensated for. The handle guide 4.3 can have an arc-shaped profile or an ascending and descending profile.

[0069] The cam carrier 9 also has an axial locking device 9.2. The axial locking device 9.2 can be designed, for example, as a locking bracket, stop, tab, spring, rib, or clamp to axially secure the cam carrier 9, for example, a camshaft, in particular a hexagonal shaft. The cam carrier 9 can be secured against axial displacement at both ends by means of such an axial locking device 9.2.

[0070] Fig. Figure 6B shows the handle element 3 in an intermediate position P3 between the use position P2 and the non-use position P1.

[0071] Fig. Figure 6C shows the handle element 3 in one of its end positions, the operating position P2, in which the grip recess 3.3 is accessible to a user's hand, for example, to operate the handle element 3 and release a locking mechanism (not shown) and allow the vehicle door to be opened. The handle support element 7.1 is partially tensioned.

[0072] As in Fig. As shown in Figure 6C, the handle element 3 and the support element 4 additionally comprise corresponding end stops, in particular a handle-side end stop 3.4 and a support-side end stop 4.4, which abut each other in the operating position P2. The handle support element 7.1 is fully tensioned.

[0073] The main cam(s) 9.1 (shown in Fig. 11) Each has a pre-curved or projecting cam contour such that, when the main cam(s) 9.1 are in the operating position P2, the corresponding cam contour secures the handle element 3 in the operating position P2, in particular by pre-tensioning it. Thus, the handle element 3 is supported by the main cam(s) 9.1 in the operating position P2.

[0074] Such a combination of a two-axis adjustment mechanism 5 with corresponding end stops 3.4, 4.4 in the operating position P2 and the main cam 9.1 supporting the handle element 3 stabilizes the end position of the handle element 3 in its operating position P2 on the support element 4. By means of the adjusting arrangement 7, in particular the main cam(s) 9.1, the end stops 3.4, 4.4 and thus the handle element 3 are clamped without play on the support element 4 and fixed in the operating position P2.

[0075] Fig. Figures 7A to 7C schematically show a sectional view of the door handle arrangement 2 in the area of ​​the support element 4 with different positions P1 to P3 of the handle element 3.

[0076] The support element 4 has bearing openings 13 for the pivot bearings 11 of the spring carrier 14, arranged in the region of the main axis HA, and of the cam carrier 9, which is rotatable about the cam axis NA, for example in the form of a hexagonal shaft. The handle bracket 3.2 also has a bearing opening 13 for the pivot bearing 11 of a handle carrier 3.5, arranged in the region of the secondary axis HiA, for example in the form of a pivot bolt or pin.

[0077] Fig. Figure 7A shows the handle element 3 in the non-use position P1.

[0078] Fig. Figure 7B shows the handle element 3 in the intermediate position P3 and Fig. Figure 7C shows the handle element 3 in the operating position P2.

[0079] Fig. Figure 8 schematically shows a rear view of the door handle arrangement 2.

[0080] The handle 3.2 has two handle arms 3.2.2 arranged parallel to each other. The handle arms 3.2.2 are profiled, in particular U-shaped.

[0081] The lever 6 comprises two lever arms 6.3, which are arranged parallel to each other and are connected to each other by means of a cross-profile 6.4, for example a crossbeam in a crossed rib structure.

[0082] Each lever arm 6.3 is arranged in a handle arm 3.2 and movably mounted there by means of a handle support 3.5, for example in the form of a bolt or pin, of the associated pivot bearing 11. In particular, each lever arm 6.3 is arranged between legs of the associated U-shaped handle arm 3.2 and movably mounted on the pivot bearing 11 about the secondary axis HiA by means of the handle support 3.5. The handle-side ends of the lever arms 6.3 mounted in the handle arm 3.2 can have a shape corresponding to the U-shaped profile of the handle arm 3.2.

[0083] The pivot bearing 11 of the main axle HA is designed as a round profile. Additionally, the pivot bearing 11 in the area of ​​the main axle HA is designed as a spring carrier 14 and is provided for receiving the return spring 12. The return spring 12 is located in the Fig. 11 and Fig. 18 shown in detail.

[0084] The pivot bearing 11 of the secondary axle HiA is designed as a handle carrier 3.5, for example in the form of a bolt or pin for the handle element 3.

[0085] In addition, the support element 4, in particular its second support part 4.2, has support elements 15 on the rear or inside, such as and / or stiffening elements 16, such as ribs, webs, profiles, etc.

[0086] The first support part 4.1 is in Fig. 8 and Fig. 9 not shown in detail. The second support part 4.2, for example, has a fastening element 17, in particular a locking device or a locking receptacle, for receiving a corresponding fastening device of the first support part 4.1.

[0087] Fig. Figure 9 schematically shows a perspective view from an oblique rear angle of the door handle assembly 2. In the area of ​​the cam axis NA, the lever 6 has the slot-shaped cam guide 6.2, in which the ends of the cam carrier 9 are movably mounted and positively guided. For mounting the cam carrier 9 in the area of ​​the cam axis NA, two central support elements 15.1 comprise semicircular bearing openings 13 for the central mounting of the cam carrier 9, and two outer support elements 15.2 comprise circular bearing openings 13 for receiving the ends of the cam carrier 9.

[0088] The lever 6 also includes a corresponding bridge 6.8 for each drive or main cam 9.1. The bridges 6.8 engage with the associated main cam 9.1 to adjust the handle element 3. Each bridge 6.8 projects inwards from the associated lever arm 6.3. Each bridge 6.8 has an angled end 6.9 along its longitudinal axis.

[0089] The bridge 6.8 has a cam-counter surface 6.10 corresponding in the direction of the main cam 9.1, as shown in Fig. Figure 10 shows this cam-type counter-surface 6.10, which is formed at the angled end 6.9 and is positioned at a small distance, for example the size of an air gap, from the associated main cam 9.1 in a retracted position of the handle element 3 (non-use position P1). During the adjustment of the handle element 3 to the use position P2, the cam-type counter-surface 6.10 engages with the associated main cam 9.1 and controls the extension movement of the handle element 3 from the non-use position P1 to the use position P2.

[0090] In the extended position (operating position P2), the cam counter surface 6.10 and the associated main cam 9.1 are engaged with each other in such a way that the respective main cam 9.1 secures and supports the grip element 3, in particular by preloading it (as in Fig. 11D shown).

[0091] Conversely, a retraction movement of the handle element 3 from the operating position P2 back to the non-operating position P1 is controlled exclusively via the auxiliary cam 9.3 and the spring carrier 14 with its projection 14.3, which is in effective engagement with it and spring-loaded.

[0092] Furthermore, the lever 6 includes two central receiving profiles 6.5 for supporting the lever 6 in the retracted state of the handle element 3 and thus in the non-use position P1 on the spring carrier 14 (in Fig. 11 and Fig. 18 shown).

[0093] Fig. Figure 10 schematically shows a perspective view of a lever arrangement with the lever 6 and its lever arms 6.3 of the adjusting mechanism 5 of the door handle arrangement 2 with the handle element 3 arranged on the lever 6. The handle element 3 is movably mounted on the lever 6 about the secondary axis HiA by means of the handle carrier 3.5 in the pivot bearing 11. The lever 6 is movably mounted about the primary axis HA on the pivot bearing 11, which is additionally designed as a spring carrier 14.

[0094] Additionally, the lever 6 between the lever arms 6.3 includes the receiving profiles 6.5 projecting inwards from these lever arms 6.3. The receiving profiles 6.5 have corresponding support surfaces 6.6 in the direction of the spring carrier 14, which, in the retracted state of the handle element 3, bear against corresponding spring stop surfaces 14.2 (in Fig. 11 and Fig. 18).

[0095] Furthermore, the lever arms 6.3 have detent projections 6.3.1 for the detent groove 6.7 of the handle support element 7.1.

[0096] Fig. Figure 11 schematically shows a perspective view of the adjustment mechanism 5 of an electrically operated door handle arrangement 1 without a lever arrangement with the lever 6 described above.

[0097] The adjusting mechanism 5 comprises the drive unit 8 with the motor 8.1, the gearbox 8.2, and the housing 8.3. When the motor 8.1 is operating, the worm shaft 8.4 drives the worm wheel 8.5 and the cam carrier 9 connected to it, causing them to rotate. Two main cams 9.1 and two auxiliary cams 9.3 are arranged on the cam carrier 9.

[0098] The main cams 9.1 serve to control the movement of the handle element 3 from the non-use position P1 to the use position P2. Each main cam 9.1 is designed, for example, as a disk with a curved or arcuate projection, or as a cam disk with a corresponding pitch or arcuate projection. To adjust the handle element 3, a rotary movement of the adjusting arrangement 7, in particular of the cam carrier 9, and thus a rotary movement of the main cams 9.1 about the cam axis NA, is converted into a translational movement, in particular a translational extension or retraction movement, of the handle element 3. The respective curved or arcuate projection of the main cams 9.1 has, for example, a variable pitch.This enables the door handle assembly 2 to absorb mechanical forces greater than 250 N when the handle element 3 is actuated, such as those that can occur, for example, when opening an iced-up door handle. Furthermore, the projection of the respective main cam 9.1, which are symmetrically designed, is configured such that, in the end position of the handle element 3 in the operating position P2 (shown with dashed lines), the main cam 9.1 is positioned against the rear of the grip surface 3.1 of the handle element 3 in such a way that it secures and supports the handle element 3, in particular by blocking it or, optionally, by pre-tensioning it.

[0099] For this purpose, the spring carrier 14 includes projections 14.3 in the direction of the auxiliary cams 9.3, which abut the auxiliary cams 9.3 in the operating position P2 and block the auxiliary cams 9.3.

[0100] Additionally, the adjustment mechanism can include 5 auxiliary cams 9.3 for decoupling a return spring assembly for the handle element 3. The spring assembly, in particular the return spring 12, is arranged on the spring carrier 14 in the region of the main axis HA. A cam-side spring end 12.1 is fixed to the cam carrier 9. An opposite spring end 12.2 is fixed to the spring carrier 14.

[0101] Furthermore, the spring carrier 14 is designed as a hollow profile and has a through-opening 14.1 into which the pivot bearing 11 of the main axle HA is received, as for example in Fig. 5 or Fig. 18 shown.

[0102] By means of such an actuating arrangement 7 with auxiliary cams 9.3 for spring decoupling, the drive device 8, in particular the motor 8.1, can be dimensioned smaller.

[0103] Additionally, actuator electronics 18, for example Hall sensors, can be provided to control the motor 8.1 for a controlled, in particular position-dependent, extension of the handle element 3.

[0104] Fig. Figures 11A and 11C to 11D schematically show in sectional view a further embodiment of a door handle arrangement 2 with cam control for different positions of the handle element 3, in particular in the area of ​​the adjustment mechanism 5 with different positions P1 to P3 of the handle element 3. In this case, one or at least two main cams 9.1 are arranged on the cam carrier 9.

[0105] Fig. Figure 11B shows an embodiment of a main cam 9.1 in detail with its cam sections 9.11 to 9.13 with variable slope profiles.

[0106] The door handle arrangement 2 comprises a support element 4, for example as previously shown by the Fig. The door handle arrangement 2 further comprises a handle element 3 which is movably arranged on the support element 4 between a non-use position P1 and a use position P2, as can be seen, for example, from the Fig. 1 to 11 were described.

[0107] The adjustment mechanism 5 for adjusting the handle element 3 relative to the support element 4 is described in detail below. The adjustment mechanism 5 comprises the lever 6 and the cam carrier 9 with at least one main cam 9.1 for controlled movement of the handle element 3 between the non-use position P1 and the use position P2.

[0108] The main cam 9.1 interacts with the cam mat 6.10 located on the lever 6. For this purpose, the main cam 9.1 has a variable cam profile, in particular a variable cam pitch or a variable projection profile. A rotation NB of the main cam 9.1, driven by the motor 8.1, causes the cam mat 6.10 to be actuated and the lever 6 to pivot accordingly (rotational movement DB) to extend or retract the handle element 3 (translational movement TB). The cam carrier 9 is coupled to the motor 8.1 and driven by it.

[0109] For example, the respective main cam 9.1 has three cam sections 9.11 to 9.13 with different cam profiles, in particular gradients. The three cam sections 9.11 to 9.13 result in different adjustment strokes of the handle element 3, as described below.

[0110] The first cam section 9.11 has a lower slope than the second cam section 9.12. Slope refers to the increase in cam radius r per angle of rotation. A third cam section 9.13 has a essentially constant slope. In other words, the third cam section 9.13 has an approximately constant cam radius per angle of rotation of the cam. The third cam section 9.13 serves to lock or block the handle element 3 in the extended position (operating position P2) on the neutral radius of the third cam section 9.13.

[0111] In one possible embodiment, the first cam section 9.11 has a first curve profile, in particular a first slope curve, wherein the main cam 9.1 and the lever 6 are slightly spaced apart from each other in the non-use position P1, as shown in Fig. 11A shown. When extending from the non-use position P1, the main cam 9.1 and the lever 6, in particular its cam counter surface 6.10, engage with each other to control the extension movement of the handle element 3.

[0112] This first cam section 9.11, in particular this first curve profile, is designed such that the force required to release the handle element 3 can be overcome when the main cam 9.1 performs a first rotary movement NB1, in particular pivoting, as is the case, for example, in Fig. 11C is shown.

[0113] Furthermore, the first curve can be designed such that, in addition to overcoming the force, the force required to release an iced-up handle element 3 is also overcome. The shallow gradient allows for the application of a large force. Additionally, the main cam 9.1 can have a cam offset 9.14, which serves as an end stop. In the non-use position P1 of the handle element 3, an end face 6.11 of the lever 6, in particular the angled end 6.9, rests against the cam offset 9.14.

[0114] The first cam section 9.11, for example, has a particularly low slope. For instance, the cam radius r doubles over a rotation angle of 180° of the main cam 9 in the first cam section 9.11.

[0115] The first cam section 9.11 is designed in particular, and especially provided with such a projection profile or such a curve profile, such that a rotation of the main cam 9.1 in the opening direction NB1 in a first rotation angle range of 160° to 200°, in particular by 180°, causes a first opening movement TB1 of the handle element 3 in an adjustment range of 4 mm to 7 mm, in particular of 5.5 mm, as can be seen from the sequence of figures. Fig. 11A and Fig. 11C is shown.

[0116] In a further embodiment, the second cam section 9.12 has such a curve profile, in particular a steep gradient, that the main cam 9.1 and the lever 6 are movable relative to each other in order to move the handle element 3 from the intermediate position P3 to the operating position P2. The retraction movement of the handle element 3 is controlled, as already described above, by the engagement of the projection 14.3 of the spring carrier 14 and the auxiliary cams 9.3 accordingly.

[0117] For example, the cam radius r triples or quadruples over a rotation angle of 180° of the main cam 9.1 in the second cam section 9.12. The second cam section 9.12 can, for example, be designed such that a rotation or pivoting of the main cam 9.1 according to a second rotational movement NB2 in a second rotational angle range of 160° to 200°, in particular by 180°, causes a second opening movement TB2 of the handle element 3 in a range of 25 mm to 30 mm, in particular 27.5 mm, as shown in the sequence of figures. Fig. 11C and Fig. 11D is shown.

[0118] The third cam section 9.13 has, in particular, a largely constant or very shallow pitch, so that the main cam 9.1 and the lever 6 enter a blocking or locking engagement in the operating position P2. In order to return from this blocking or locking engagement to the intermediate position P3 or the non-operating position P1 when the handle element 3 is adjusted, the auxiliary cams 9.3 engage with the projections 14.3 of the spring carrier 14.

[0119] This third cam section 9.13 engages in a blocking or locking engagement, in particular a friction engagement, with the cam mating surface 6.10 on the lever 6 when the handle element 3 is in the operating position P2. This third cam section 9.13 is designed such that the force required to release the engagement, even if the handle element 3 is at least slightly frozen, can be overcome when the main cam 9.1 is moved in the closing direction TB3. Depending on the type and design of the drive, particularly in the case of a motor 8.1, the cam section 9.13 can be designed such that the handle element 3 cannot be forced into the intermediate position P3 or the non-operating position P1 by hand.

[0120] Another aspect provides that the cam carrier 9 comprises several main cams 9.1 which are designed to correspond to each other.

[0121] Fig. 12 and Fig. Figure 13 shows schematic views of a manually operated door handle assembly 20 with different positions of the handle element 3. Instead of the drive device 8, the door handle assembly 20 includes a manual switching element 19, for example a slider or a push button. When the switching element 19 is actuated, the handle element 3 is moved from the non-use position P1 to the use position P2 due to a motion coupling of the switching element 19 with the actuating arrangement 7, in particular the main cam 9.1.

[0122] Fig. 14 and Fig. Figure 15 shows the manually operated door handle assembly 20 in the extended operating position P2. To trigger or open the door lock (not shown in detail), the extended handle element 3 can then be moved, for example by means of a vertical movement according to arrow PF.

[0123] Fig.Figures 16 to 19 show schematic views of a door handle arrangement 2 with an optional functional unit designed as a mechanical emergency operating unit 10.

[0124] The emergency actuation unit 10 comprises one or more manual actuating elements 10.1, 10.2.

[0125] A front actuating element 10.1 rotates when pressed, thereby actuating, for example, a Bowden cable 10.4 for emergency release and opening. A rear actuating element 10.2 is designed like a drawer, the engagement of which is concealed by a flap 10.3. If a user, for example, pushes the flap 10.3 in with a finger, the drawer can then be pulled with this finger (also a rotary and / or linear movement), thereby actuating the Bowden cable 10.4 for emergency release and closing the flap 10.3 again.

[0126] The actuating element 10.2 can also be coupled to a coupling element 10.5, which in turn is motion-coupled to the cam carrier 9, so that when the actuating element 10.2 is actuated by a user, the cam carrier 9 is moved and the handle 3 is manually actuated.
