Description

Technical Field

[0001] The present invention relates to a door handle assembly for a motor vehicle, comprising an electromechanical locking system with a door lock, a handle bracket capable of being fastened to a motor vehicle door, and a handle element mounted on the handle bracket in a manner pivotable via a pivot axis. The handle element is configured to be manually actuated and capable of moving from a rest position to an actuation position for electronically unlocking the door lock or to an emergency actuation position beyond the actuation position for mechanically unlocking the door lock. Background Technology

[0002] Such door handle assemblies are known in the prior art. In these known door handle assemblies, a resistance device that increases actuation resistance takes effect at the end of the first actuation path of the manually actuated handle element, such that the switch for electronically opening the door lock is actuated only after or upon overcoming a perceptible pressure point, thus enabling the door lock to be opened electronically. The resistance device is here configured as a spring element, increasing the force required by the user for electronic opening. If the handle element deflects along a second actuation path beyond the first, the door lock is mechanically opened in an emergency, such as when the vehicle battery is depleted, where the actuating force required by the user is significantly greater than that required for electronic opening. Due to the design of this known door handle assembly, a high actuating force is required to move the handle element in both normal operation and emergency operation modes without power, which adversely limits the comfort of the door handle assembly. Summary of the Invention

[0003] The object of the present invention is to create a solution that provides an improved door handle assembly in a simple design manner, which overcomes the aforementioned disadvantages and enables the user to operate the handle element comfortably.

[0004] According to the present invention, this objective is achieved by a door handle assembly having the features of claim 1.

[0005] The vehicle door handle assembly according to the invention includes an electromechanical locking system with a door lock, a handle bracket capable of being fastened to a vehicle door, a handle element pivotally supported on the handle bracket via a pivot axis (the handle element is configured to move manually from a rest position to an actuation position for electronically unlocking the door or to an emergency actuation position beyond the actuation position for mechanically unlocking the door), a stop element supported on the handle element movable between a base position and an offset position (the stop element is configured to have a first longitudinal end and a second longitudinal end and a neck-like section connecting the first longitudinal end and the second longitudinal end and a head section located on the second longitudinal end that is configured to be wider than the neck-like section), and an opposing stop element supported on the handle bracket movable between a blocking position and a release position, the opposing stop element being configured to have a gap of variable width in a manner similar to a separated curtain. In the base position of the handle element, the neck segment of the stop element arranged in the base position is arranged to pass through the gap of the opposing stop element arranged in the blocking position, and the opposing stop element is arranged between the head segment and the handle bracket. When the handle element is manually moved from the rest position to the actuated position by means of a first user force, the opposing stop element still arranged in the blocking position is configured to prevent the handle element from moving past the actuated position, and the head segment of the stop element still arranged in the base position abuts against the gap that is configured to be narrower than the head segment in the blocking position. When the handle element is manually moved from the actuated position toward the emergency actuated position by means of a second user force that is greater than the first user force, the head segment of the stop element still arranged in the base position is configured to squeeze the opposing stop element from the blocking position to the release position. In the release position, the gap is configured to be wider than the blocking position and allow the head segment to pass through the gap.

[0006] Advantageous and suitable designs and improvements of the present invention are derived from the corresponding dependent claims.

[0007] This invention provides a door handle assembly characterized by its simple and low-cost construction. In the door handle assembly according to the invention, the door lock of a motor vehicle is opened electronically with a small first user force. An opposing stop element in this case prevents movement of the stop element and thus prevents the handle element from moving beyond the actuation position, thereby providing the user with tangible feedback that the movement for electronic opening has been completed. In an emergency operation without power, the user must apply a second user force greater than the first user force. By applying this second user force, the stop element overcomes the opposing stop element, where an emergency actuation force, less than the second actuation force required to overcome the opposing stop element, is needed to further rotate the handle element to the emergency actuation position. The emergency actuation force applied by the user only needs to be large enough, for example, for use in opening a Bowden cable system. Therefore, for actuating the door handle assembly according to the invention, the user advantageously always requires only a minimal amount of force.

[0008] The present invention is designed such that the opposing stop element in the actuated position of the handle element is configured as a mechanical stop that can be felt by a user actuating the handle element with a first user force. Therefore, the user receives direct and perceptible feedback from the handle element regarding actuation sufficient to open it electronically.

[0009] In a further design of the invention, it is also advantageous that the opposing stop element is configured to provide resistance that can be overcome as the handle element moves from the actuated position toward the emergency actuated position. This design also provides the user with perceptible feedback regarding the actuation process applied by the user to the handle element.

[0010] A particularly advantageous structural feature of the invention is that, in the design of the present invention, when the handle element moves from the emergency actuation position back to the rest position, the opposing stop element, still arranged in its blocking position, is configured to press the stop element from the base position to the offset position, in which at least the head segment of the stop element is arranged to move outside the gap. Because the opposing stop element remains in its blocking position in this way and only the stop element moves to the offset position upon returning to its base position, the risk of failure when only one of the two elements (in this case, the stop element) needs to move is minimized.

[0011] In a further design, the present invention specifies that the opposing stop element is configured to have a contour portion that compresses the stop element from a base position to an offset position, wherein, when the handle element moves from an emergency actuation position to an actuation position, the head segment of the stop element is arranged to abut against the contour portion formed in the gap region. The contour portion enables the stop element to be guided back to the base position in a structurally simple manner, without having to flip or move the opposing stop element in any way.

[0012] In order to enable the movement of the stop element when it moves to the base position, the present invention further specifies, for the minimum installation space, that the first longitudinal end of the stop element is rotatably supported on the handle element and the stop element is configured to be able to move in a rotating manner from the base position to the offset position against the force of the mechanical reset device.

[0013] In another design of the invention, the opposing stop element has two blocking elements that are movably supported side-by-side on the handle bracket. By means of the two blocking elements, the opposing stop element is thus constructed as if it were a separated curtain.

[0014] Therefore, the gap between the opposing stop elements is configured such that its width can vary. In a further design, the invention specifies that the two stop elements are held in the guide such that the two stop elements are supported in a manner that allows them to move toward each other to narrow the gap and to move away from each other to widen the gap.

[0015] One structurally advantageous possible solution for designing a blocking element is obtained by the following method: the corresponding blocking element is constructed as a blocking plate capable of translational displacement, wherein two blocking plates are supported in a manner that allows translational movement in a guide formed on a handle support.

[0016] This design allows for a simple way to achieve the gap by constructing the side edges of each stop plate with recesses, wherein the recesses of two stop plates are arranged opposite each other and form a variable gap for opposing stop elements.

[0017] To allow for gap variation, this invention further specifies that the two baffles are configured to move from a blocking position to a releasing position against the force of the mechanical reset element. The mechanical reset element is configured as a torsion spring having a first spring arm and a second spring arm, wherein the first spring arm extends parallel to the second spring arm and is supported on one of the two baffles while the second spring arm is supported on the other of the two baffles.

[0018] An advantageous and beneficial possible solution for returning the stop element in the event of emergency actuation is specified in the design of the present invention by the following manner: the corresponding blocking element is configured to have a profile surface that compresses the stop element from the base position to the offset position, wherein, when the handle element moves from the emergency actuation position to the actuation position, the head segment of the stop element is arranged to abut against the profile surface formed in the gap region.

[0019] An alternative to a structurally advantageous design for a blocking element is obtained by configuring the corresponding blocking element as a rotatable blocking plate, wherein the corresponding blocking plate has a blocking section and a supporting section, wherein the corresponding supporting section has an arc-shaped supporting edge, and wherein the arc-shaped supporting edges of the two blocking plates are configured to have different radii, such that the supporting edge of one blocking plate is supported within the supporting edge of the other blocking plate and these supporting edges are supported in a manner that allows them to rotate relative to each other.

[0020] In order to securely support the blocking element, the invention further specifies that the two blocking plates are supported in a manner that allows them to move along the guide surface of the supporting element, wherein the supporting element supports the two blocking plates in a pivotable manner.

[0021] To change the gap, this invention specifies that the two blocking plates are configured to move from the blocking position to the releasing position against the force of the mechanical reset element, wherein the mechanical reset element is configured as a torsion spring having a first spring arm and a second spring arm, wherein the first spring arm extends parallel to the second spring arm and is supported on one of the two blocking plates while the second spring arm is supported on the other of the two blocking plates.

[0022] In order to reset the stop element in the event of emergency actuation, the design of this variant specifies that the corresponding stop plate is configured to have a profile surface that presses the stop element from the base position to the offset position, wherein, when the handle element moves from the emergency actuation position to the actuation position, the head section of the stop element is arranged to abut against the profile surface formed in the gap area.

[0023] The present invention provides an alternative to the structurally advantageous design of the blocking element by means of the following: the corresponding blocking element is constructed as a blocking roller capable of translational displacement, wherein two blocking rollers are supported in a manner that allows them to translate within a guide arranged on a handle bracket.

[0024] In another design of the above alternative, the invention further specifies that: two blocking rolling elements are configured to move from a blocking position to a releasing position against the force of the mechanical reset element, wherein the mechanical reset element is configured as a torsion spring having a first spring arm and a second spring arm, wherein the first spring arm extends parallel to the second spring arm, and wherein the first spring arm rotatably supports one of the two blocking rolling elements while the second spring arm rotatably supports the other of the two blocking rolling elements.

[0025] In order to reset the stop element in the event of emergency actuation, the design of the above variant specifies that the corresponding blocking roller is configured to have a profile surface that presses the stop element from the base position to the offset position, wherein, when the handle element moves from the emergency actuation position to the actuation position, the head section of the stop element is arranged to abut against the profile surface formed in the gap area.

[0026] Another alternative to the aforementioned alternatives and designs is specified in the design of the present invention in such a way that the opposing stop element has two blocking elements and a support housing fastened to or constructed integrally with the handle bracket, wherein the two blocking elements are movably supported on the support housing such that the two blocking elements are supported so as to be able to move toward each other to reduce the gap and to move away from each other to increase the gap.

[0027] In this alternative, the structural advantage is that the opposing stop element has a mechanical reset element, through which two blocking elements are connected, wherein the two blocking elements are supported in the support housing in such a way that they can move from the blocking position to the release position against the force of the mechanical reset element.

[0028] Structurally, particularly advantageously, in a further design of this alternative, the mechanical reset element has a first spring arm and a second spring arm, wherein the first spring arm is supported on one of the two blocking elements and the second spring arm is supported on the other of the two blocking elements.

[0029] In another alternative, the invention specifies that the opposing stop element has an insert element arranged on the support housing and configured to at least partially retain the first and second spring arms. During movement, a blocking element pressing against the spring arms causes the spring arms to move when they reach the release position, and the spring arms are correspondingly held by the insert element.

[0030] In a further design of another alternative, the embedded element is configured to have a guide, in which the first spring arm and the second spring arm are arranged at least partially, wherein the guide is configured to cause the first spring arm and the second spring arm to move in a directional and guided manner as the two blocking elements move.

[0031] A particularly cost-effective alternative is that, in another option, the insert element is made of steel and / or the support housing is made of plastic. Since only the insert element needs to withstand a certain force, it is more economically advantageous for only the insert element to be made of a high-strength material, which has higher strength than the material of the support housing.

[0032] Finally, in another alternative, the design can be made such that the corresponding blocking element is constructed as a blocking plate, a blocking sheet, or a blocking roller supported in a displaceable manner.

[0033] In another alternative design, the corresponding blocking element is configured as a blocking plate supported in a displaceable manner, wherein the corresponding blocking plate has a blocking section and a supporting section, wherein the corresponding supporting section has an arc-shaped supporting edge, and wherein the arc-shaped supporting edges of the two blocking plates are configured to have different radii, such that the supporting edge of one blocking plate is supported within the supporting edge of the other blocking plate and the supporting edges are supported in a manner that allows them to rotate relative to each other.

[0034] The structure is also particularly advantageous in that the head section has a sliding surface that is configured to extend at an angle. The sliding surface is configured to abut against the variable gap between the two blocking elements when the movement reaches the emergency actuation position, so that the two blocking elements move away from each other and separate from each other and the gap widens.

[0035] A particularly advantageous structural feature for electronic opening is that the handle element is configured to interact with a microswitch, allowing the lock to be opened electronically before or when the handle element reaches the actuation position.

[0036] Similarly, structurally advantageous for mechanical opening is that the handle element is configured to interact with the Bowden line, so that the lock opens mechanically when the handle element reaches the emergency actuation position.

[0037] It should be understood that the features described above and below can be used not only in the combinations given, but also in other combinations or individually, without departing from the scope of the invention. The scope of the invention is defined only by the claims. Attached Figure Description

[0040] exist Figure 1The image exemplarily shows a vehicle or motor vehicle 1 in the form of a passenger car, which in this example has four doors 2 (two of which are in…). Figure 1 (As can be seen in the image), these doors can be opened via the door handle assembly 3 and specifically by means of the handle element 4. (See reference...) Figure 1 and Figure 2 The door 2 is locked by a corresponding door lock 5 and can be opened from the outside by correspondingly actuating the handle element 4. The handle element 4 has a grippable handle portion 6 that can be actuated to unlock the door lock 5, wherein, in the illustrated embodiment, the actuation is a pulling force applied by the user to the handle element 4, which is detected by a sensing device 7 installed in the door handle assembly 3. To open the door 2, an electromechanical locking system 8 is activated in normal operation, by means of which the door lock 2 can be opened or locked. Different solutions for the sensing device 7 are known from the prior art and can also be applied to the door handle assembly 3 according to the invention. Therefore, switches or buttons, as well as capacitive or inductive sensors, can be used on the door handle assembly 3, for example.

[0041] Figure 2 As can be observed, the handle element 4 is arranged on the outside of the door 2 of the motor vehicle 1, wherein the handle element can be gripped by a user. To attach the handle element 4 to the door 2, a handle bracket 9 configured as a frame is provided, which is arranged on the inside of the door 2. The handle bracket 9 is fastened to the inside of the door 2 by known fasteners and supports the handle portion 6 of the handle element 4 arranged on the outside of the door 2. The movement of the handle element 4 during normal operation of the door handle assembly 3 is controlled by a sensing device 7 configured as a microswitch (Mikrotaster) 10 (see [link to sensor]). Figure 5 Upon identification, the door lock 5 of door 2 is then electronically unlocked. The corresponding door 2 can be opened by moving the handle element 4 accordingly. In the context of this invention, "normal operation" is understood as the operating mode in which the door handle assembly locks and unlocks the door (and cover) electrically via a drive unit. To open the door handle assembly 3 electronically during normal operation, the user moves the handle element 4 from its rest position to its actuated position, thereby pivoting the handle element 4 to a certain extent (in the current embodiment, the pivot angle is 5°) and actuating the microswitch 10. The microswitch then activates the electromechanical locking system 8, by which the door lock 5 can be opened. The door handle assembly 3 is also configured for emergency operation in the absence of power, in which the vehicle's electronic systems cease operation (e.g., when the vehicle battery is depleted), and the user must manually move the handle element 4 from its rest position past the actuated position to the emergency actuated position. The Bowden line system 11 is activated by pivot actuation element 4 (in the current embodiment, the pivot angle is approximately 30°), which in turn enables... Figure 6 It is shown in detail in the text.

[0042] exist Figure 1 and Figure 2 In the present invention, the door handle system 3 is shown in a very common form, while... Figures 3 to 6 In the figure, door handle assembly 3 is drawn with reference to the embodiment shown. Besides... Figures 3 to 6 The door lock 5 and electromechanical door locking system 8, not shown, according to the invention, the door handle assembly 3 has a handle bracket 9 capable of being fastened to the door 2 and a handle element 4 with a handle portion 6. Figure 4 In the diagram, the handle bracket 9 is omitted for clarity, allowing observation that the handle element 4 consists of a handle portion 6 and two swing arms 12. Each swing arm 12 is supported at one end on a pivot shaft 14, and the handle portion 6 is fastened to the other end of the corresponding swing arm 12. Thus, the handle element 4 is supported on the handle bracket 9 in a manner that allows it to pivot on the pivot shaft 14, enabling manual actuation of the handle element 4 to move from a rest position to an actuated position for electronically unlocking the door or to an emergency actuated position for mechanically unlocking the door, beyond the actuated position. The manual movement of the handle element 4 is against the force of the spring elements 15, which apply a force that pushes the handle element 4 back to its rest position. Figure 5 The detailed illustration shows the interaction between the handle element 4 and the microswitch 10 for electronic activation. The handle element 4 acts on an actuating surface 16, which is formed on an adjusting rod 17 rotatably supported on the handle bracket 9 and configured with an increasing radius, such that the adjusting rod 17 rotates when the handle element 4 pivots, and in the actuated position, the actuating surface 16 actuates and compresses the microswitch 10 with its maximum radius. Figure 6 In the side view, the Bowden cable system 11 can be observed. This system is connected to the door lock 5 via a Bowden cable (not shown) and is used for mechanical opening. The Bowden cable system 11 is pivotally supported on the handle bracket 9 and is movably coupled to the handle element 4, such that movement of the handle element 4 from the rest position to the emergency actuation position causes the Bowden cable system 11 to pivot for mechanical opening. This is generally known and therefore will not be described further or in more detail.

[0043] The construction of the door handle assembly 3 described above is the same for the four embodiments described in detail below.

[0044] The following reference Figures 7 to 34. Four embodiments of the present invention will be described. In all four embodiments, the door handle assembly 3 has a stop element 18, which is supported on the handle element 4 in a manner that allows it to move between a base position and an offset position. The stop element 18 is configured to have a first longitudinal end 19 and a second longitudinal end 20, for example, made of… Figure 10 As can be seen, the first longitudinal end 19 and the second longitudinal end 20 are connected to each other via the neck-shaped section 21. The stop element 18 has a head section 22 on the second longitudinal end 20 that is configured to be wider than the neck-shaped section 21, while a support shaft 23 is formed on the first longitudinal end 19. The support shaft extends transversely to the neck-shaped section 21 and is supported on the handle bracket 9 in a rotatable manner, capable of overcoming the force of the mechanical reset device 24 (configured as a reset spring in four embodiments) to rotate from the base position to an offset position. A sliding surface configured to extend obliquely is also formed on the widened head section 22, extending from the second longitudinal end 20 toward the neck-shaped section 21, and the width of the widened head section 22 continuously decreases to the width of the neck-shaped section 22, for example, by the method described in the four embodiments. Figure 10 , Figure 22 , Figure 27 as well as Figure 30 As can be seen. Furthermore, in all four embodiments, the door handle assembly 3 has an opposing stop element 26 supported in a manner capable of moving between a locked position and a released position. Here, the opposing stop element 26 can be directly or indirectly mounted on the handle bracket 9. In all three embodiments, the opposing stop element 26 is configured as if a curtain were separated, with a gap 28 of variable width 27, which will be discussed further below. The opposing stop element 26 is also configured in all four embodiments to have a contour portion 29. In particular, in all four embodiments, the opposing stop element 26 has two blocking elements 30a and 30b, which are movably supported side-by-side on the handle bracket 9. Finally, in all four embodiments, the two blocking elements 30a and 30b are held in the guide 31 (see, for example, see...). Figure 8 , Figure 21 , Figure 25 and Figure 32 The two blocking elements 30a and 30b are supported in such a way that they can move toward each other to close the gap 28 and move away from each other to widen the gap 28.

[0045] Figures 7 to 19A first embodiment of the present invention is shown, which will be described in detail below. In the first embodiment, the corresponding blocking elements 30a and 30b are configured as blocking plates 32a and 32b capable of translational displacement. The corresponding blocking plates 30a and 32b are configured as plates or as rectangular flat plates. The two blocking plates 32a and 32b are supported in a guide 33 formed on the handle bracket 9 in a manner capable of translational movement. In the guide 33, the two blocking plates 32a and 32b are supported by side edges in a manner capable of translational displacement, for example by... Figure 8 As can be seen, the two blocking plates 32a and 32b are further configured to overcome the force of the mechanical reset element 34 from the blocking position (see...). Figure 12 , Figure 13 and Figure 16 Move to the release position (see) Figure 14 Mechanical reset element 34 (e.g., made of...) Figure 8 (As can be seen) A torsion spring 35 is constructed having a first spring arm 36a and a second spring arm 36b, wherein the first spring arm 36a extends parallel to the second spring arm 36b. A helical section connecting the two spring arms 36a and 36b is supported on a receiving portion of the handle bracket 9. Furthermore, the first spring arm 36a is supported on a stop plate 32a, while the second spring arm 36b is supported on a stop plate 32b. The two free ends of the spring arms 36a and 36b are supported in a displaceable manner in a guide 31. For example, by Figure 15 It can be observed that the side edges of the corresponding baffles 32a and 32b are configured to have recesses 37. The recesses 37 on the baffles 32a and 32b are configured on the opposing side edges of the baffles 32a and 32b, forming a variable gap 28 for the opposing stop element 26. Accordingly, the recesses 37 of the two baffles 32a and 32b are configured to be arranged opposite each other. Finally, the corresponding stop elements 30a and 30b are configured to have the ability to move the stop element 18 from its base position (see [reference]). Figure 12 Squeeze to the offset position (see) Figure 17 , Figure 18 and Figure 19 The profile surface 38 is configured as an inclined extending surface and corresponds to the previously mentioned profile portion 29 of the opposing stop element 26.

[0046] The following will be based on Figures 12 to 19 The operation of the door handle assembly 3 according to the present invention is described with reference to the first embodiment, wherein the operation is generally the same for all four embodiments.

[0047] exist Figure 12In this configuration, the handle element 4 is positioned in a rest position, which corresponds to its initial position when unacted. In this rest position, the neck-shaped segment 21 of the stop element 18, positioned in its base position, extends through the gap 28 of the opposing stop element 26, which is positioned in its blocking position. In other words, the neck-shaped segment 21 of the stop element 18 extends through the gap 28 formed by the recesses 37 of the blocking plates 32a and 32b, such that when the handle element 4 is positioned in its rest position, the blocking plates 32a and 32b are positioned between the head segment 22 and the handle bracket 9. Therefore, in the rest position, the opposing stop element 26 is positioned between the head segment 22 and the handle bracket 9. The variable gap 28 has a minimum width 27 in the rest position of the handle element 4.

[0048] exist Figure 13 In this configuration, the handle element 4 is arranged to move from a rest position to an actuated position, wherein, in order to perform this movement, the handle element 4 is manually actuated by a user using a first user force. The opposing stop element 26 is further arranged in its blocking position to remain stationary in the actuated position of the handle element 4. The head segment 22 of the stop element 18, which is linked to the handle element 4, is here arranged to move toward the gap 28. As long as the user actuates the handle element 4 with the first user force, the blocking plates 32a, 32b of the opposing stop element 26 prevent the handle element 4 from moving beyond the actuated position. Therefore, when the handle element is manually moved from the rest position to the actuated position by means of the first user force, the opposing stop element 26, still arranged in the blocking position, is configured to prevent the handle element 4 from moving beyond the actuated position, wherein the head segment 22 of the opposing stop element 26, still arranged in its blocking position, abuts against the gap 28, which is configured to be narrower than the head segment 22 in the blocking position. The opposing stop element 26 is thus configured in the actuated position of the handle element 4 as a mechanical stop that is more noticeable to the user actuating the handle element 4 by the first user force. The width 27 of the gap 28 in the operating position of the handle element 4 is equivalent to the width 27 of the handle element 4 when it is positioned in its rest position. The handle element 4 pivots about 5° about the pivot axis 14 as it moves from the rest position to the operating position, wherein the micro switch 10 is activated by the activation surface 16 in the operating position to open electronically. Accordingly, the handle element 4 is configured to interact with the micro switch 10 such that the door lock 5 is opened electronically before or when it reaches the actuated position of the handle element 4.

[0049] In the context of this invention, for all four embodiments, the opposing stop element 26 is configured to overcome an obstacle when the handle element 4 moves from the actuated position toward the emergency actuated position. Referring to the first embodiment and... Figure 14 and Figure 15If an emergency operation occurs due to power failure and the device cannot be opened electronically, the user must apply a second user force to the handle element 4 positioned in the operating position to overcome this obstacle. With this second user force, the handle element 4 can move past the operating position toward the emergency operation position for mechanical opening. Figure 14 and Figure 15 In the position shown, handle element 4 is arranged to move from the operating position toward the emergency operating position. During this movement, stop element 18 pushes the two blocking elements 30a, 30b, or the two blocking plates 32a, 32b facing the opposing stop element 26, apart like a separated curtain. Figure 15 and Figure 15 As indicated by the arrows in the diagram. The movement of the two blocking elements 30a, 30b or the two blocking plates 32a, 32b is achieved by means of the guide 33, such that the movement of the two blocking elements 30a, 30b or the two blocking plates 32a, 32b is a translational movement parallel to the handle bracket 9. The movement of the two blocking elements 30a, 30b or the two blocking plates 32a, 32b is also carried out against the force of the mechanical reset element 34 or the torsion spring 35, wherein the two spring arms 36a and 36b are moved away from each other in their guide 31. By means of the sliding surface 25 formed on the head section 22 of the stop element 18, the blocking plates 32a and 32b move away from each other in a translational manner, thereby widening the width 27 of the variable gap 28 until the head section 22 can move through the two blocking elements 30a, 30b or the blocking plates 32a, 32b. Correspondingly, when the handle element 4 is manually moved from the actuated position toward the emergency actuated position by a second user force greater than the first user force, the head segment 22 of the stop element 18, still arranged in its base position, is configured to press the opposing stop element 26 from the blocking position to the release position, in which the gap 28 widens relative to the blocking position and is configured to allow the head segment 22 to pass through the gap 28. The stop element 18 here remains in its base position, wherein the stop element is arranged on the handle element 4 in a non-moving and non-pivoting manner. Conversely, the opposing stop element 26... Figure 14 and Figure 15 It is in the release position.

[0050] If the head section 22 of the stop element 18 has been pre-arranged between the two blocking elements 30a, 30b or the two blocking plates 32a, 32b of the opposing stop element 26, and the width 27 of the gap 28 is expanded corresponding to the width of its head, then the obstruction formed by the opposing stop element 26 is overcome, and the user can move the handle element 4 to the emergency actuation position with an emergency user force lower than the second user force. The arrangement of the stop element 18 and the opposing stop element 26 is as follows: Figure 16As shown in the diagram, the blocking elements 30a, 30b or blocking plates 32a, 32b of the opposing stop element 26 are arranged to return to the blocking position. The force of the mechanical reset element 34 causes the blocking elements 30a, 30b or blocking plates 32a, 32b to be pressed back together and reduces the width 27 of the variable gap 28. The handle element 4 is configured to interact with the Bowden line 11, such that the door lock 5 is mechanically opened when the handle element 4 is in the emergency actuation position.

[0051] exist Figures 17 to 19 The image shows the position of the stop element 18 when the handle element 4 returns from the emergency actuation position to the rest position, wherein the handle element 4 is in Figure 17 The middle was arranged to pivot 10° and in Figure 18 and Figure 19 The handle element 4 is pivoted by 5° (equivalent to the operating position). When the handle element 4 moves from the emergency actuation position to the stationary position, the head section 22 of the stop element 18 abuts against the profile portion 29 of the opposing stop element 26 or against the profile surface 38 of the stop plates 32a, 32b. Correspondingly, when the handle element 4 moves from the emergency actuation position to the actuation position, the head section 22 of the stop element 18 is arranged to abut against the profile surface 38 formed in the area of ​​the gap 28. When the handle element 4 moves further, the stop element 18, which is pivotally supported on the handle element 4, is arranged to overcome the force of the mechanical reset device 24 and pivot relative to the handle element 4 from its base position to the operating position. Figures 17 to 19 The offset position is shown. Therefore, when the handle element 4 returns from the emergency actuation position to the rest position, the opposing stop element 26, still arranged in its blocking position, is configured to press the stop element 18 from the base position to the offset position, in which at least the head segment 22 of the stop element 18 is arranged to move outside the gap 28. The head segment 22 of the stop element 16 thus pivots, causing the head segment 22 to move back below the opposing stop element 26 to behind the opposing stop element 26. When the stop element 26 moves from the rest position to the emergency actuation position of the handle element 4, the head segment 22 of the stop element 26 passes through the gap 28 and here widens the width 27 of the gap 28 until the head segment 22 can pass through the gap 28, while when the handle element 4 returns from the emergency actuation position to the rest position, the head segment 22 is arranged outside the gap 28 and does not pass through the gap.

[0052] The process of the handle element 4 moving from the rest position to the actuation position and the emergency actuation position, and the process of the handle element 4 returning from the emergency actuation position to the rest position are similar in the second, third and fourth embodiments. Therefore, the above description is also valid for the second, third and fourth embodiments. Therefore, the following will mainly discuss the special features of the second, third and fourth embodiments, and the various positions will not be discussed in detail again, nor will they be shown in the accompanying drawings.

[0053] Figures 20 to 23 A second embodiment of the door handle assembly 3 according to the invention is shown, wherein the corresponding blocking elements 30a, 30b are configured as rotatable blocking plates 39a and 39b. Figure 20 The image shows a detailed rear view of the door handle assembly 3, in which the opposing stop element 26 has a housing 40 which is detachably mounted on the handle bracket 9 and the stop plates 39a and 39b are pivotally supported in the housing. Figure 21 The assembled opposing stop element 26 is shown, but it has not yet been mounted on the handle bracket 9. Figure 23 As can be observed from the single-part drawing, the opposing stop element 26 has a mechanical reset element 41 outside the housing 40 and the stop plates 39a and 39b. The mechanical reset element is further configured as a torsion spring 42 with two spring arms 43. The torsion spring 42 is supported on a support shaft 44, which is formed within the housing 40. Figure 21 and Figure 23 As shown. In the second embodiment, the free end of the spring arm 43 is also movably supported in the guide 31, which is formed on the housing 40. The corresponding spring arm 43 is supported on the blocking plate 39a or 39b assigned thereto. The corresponding blocking plates 39a and 39b have blocking sections 45 and support sections 47, wherein the corresponding support sections 47 are pivotally supported on the support shaft 44 of the housing 40. The corresponding blocking sections 45 are constructed according to the type of plate, wherein gaps 28 are formed between the two blocking sections 45 and on the adjacent edges of the blocking plates 39a and 39b. The corresponding support sections 46 have arc-shaped support edges 47, wherein the arc-shaped support edges 47 of the two blocking plates 39a and 39b are constructed to have different radii, for example by Figure 21 and Figure 23 As observed, due to their different radii, the support edge 47 of one stopper 39a is supported in a space-saving manner within the support edge 47 of the other stopper 39b, wherein the support edges 47 are also supported about the support axis 44 in a manner that allows them to rotate relative to each other. A guide surface 48 is also formed on the housing 40, wherein the two stoppers 39a and 39b are supported in a manner that allows them to move along the guide surface 48 of the housing 40, which is configured as a support element, and the support element or housing 40 supports the two stoppers 39a and 39b in a pivotable manner.

[0054] According to Figures 20 to 23In the second embodiment, the two stop plates 39a and 39b are configured to move from the stop position to the release position against the force of the mechanical reset element 41. The stop element 18 thus presses the stop plates 39a and 39b out of its movement path via its sliding surface 25 formed on the head section 22, and widens the gap 28 for mechanical opening when the handle element 4 moves from the running position to the emergency actuation position, as described above with respect to the first embodiment. For the movement of the handle element 4 from the emergency running position back to the stationary position, the corresponding stop plates 39a and 39b are configured to have a profile surface 49 that presses the stop element 18 from the base position to the offset position. When the handle element 4 moves from the emergency actuation position to the actuation position, the head segment 22 of the stop element 18 is arranged to abut against the profile surface 49 formed in the region of the gap 28. The profile surface 49 is configured to cause the stop element 18 to pivot due to the profile surface 49 when the handle element 4 moves from the emergency actuation position back to the rest position, and to cause the head segment 22 to be arranged outside the gap 28 during the return movement, thereby allowing the head segment 22 to bypass the opposing stop element 26, which is configured to obstruct movement. Figure 22 In the top view, the handle element 4 is arranged in its rest position, so the head section 22 is positioned at a distance from the gap 28. When the handle element 4 moves from the rest position to the operating position, the head section 22 of the stop element 18 abuts against the gap 28, thereby activating the micro switch 10 by the actuation surface 16 and opening the door electronically during normal operation. In an emergency operation where opening cannot be achieved electronically, the handle element 4 is further rotated outward by a second user force, thereby pressing the head section 22 of the stop element 18 against the blocking plates 39a and 39b with its sliding surface 25, overcoming the opposing stop element 26 that acts as an obstacle. Here, the blocking plates 39a and 39b rotate away from each other around the support shaft 44, with this movement being against the force of the mechanical reset element 41. Once the obstacle is overcome, the user can move the handle element 4 to the emergency actuation position with less force to open it mechanically. The movement from the emergency actuation position back to the stationary position (where the head segment 22 of the stop element 18 is arranged to move outside the gap 28 via the profile surface 49) has been described above.

[0055] final, Figures 24 to 28A third embodiment of the door handle assembly 3 according to the invention is shown. In the third embodiment, the corresponding blocking elements 30a and 30b are configured as translationally displaceable blocking rollers 50a and 50b. The blocking rollers 50a and 50b are supported in a translationally displaceable manner relative to the handle housing 9, wherein the blocking rollers 50a and 50b are also supported in a rotatable manner. By means of a guide 31 formed on a guide element 51 that can be mounted on the handle bracket 9, the blocking rollers 50a and 50b are supported in a translationally movable manner relative to the handle bracket 9. In terms of the translational movement of the blocking rollers 50a and 50b, the two blocking rollers 50a and 50b are configured to move from the blocking position to the release position against the force of the mechanical reset element 52. In the third embodiment, the mechanical reset element 52 is also configured as a torsion spring 53 having a first spring arm 54 and a second spring arm 54, wherein the first spring arm 54 extends parallel to the second spring arm 54. Here, the blocking rollers 50a and 50b are rotatably supported on corresponding spring arms 54. Specifically, the corresponding blocking rollers 50a and 50b are constructed as cylindrical rollers, each supported at its center by a torsion spring 53 of the mechanical reset element 52. The blocking rollers 50a and 50b are made of hard rubber and rotate when the handle element 4 is pulled from the actuated position to the emergency actuated position, wherein the spring arms 54 are simultaneously separated by pressure within the guide 31 in directions away from each other. The advantage of using blocking rollers 50a and 50b with hard rubber is minimal friction and minimal noise generation. Similarly, in the third embodiment, a contour surface 55 is formed on the blocking rollers 50a and 50b, which presses the stop element 18 from the base position to the offset position when the handle element 4 moves from the emergency actuated position to the stationary position. The profile surface 55 is conical and extends from a segment of either of the blocking rollers 50a, 50b toward the free end of the spring arm 54. When the handle element 4 moves from the emergency actuation position to the actuation position, the head segment 22 of the stop element 18 is arranged to abut against the profile surface 55 formed in the region of the gap 28. The head segment 22 also has a sliding surface 25 configured to extend obliquely, which, when moved to the emergency actuation position, abuts against the variable gap 28 between the two blocking elements 30a, 30b or the two blocking rollers 50a, 50b, moving the two blocking elements 30a, 30b or the blocking rollers 50a, 50b away from each other and separating them, thus widening the gap 28. In the third embodiment, when the handle element 4 moves from the stationary position to the operating position, the head section 22 of the stop element 18 abuts against the gap 28, thereby activating the micro switch 10 by the actuation surface 16 and opening the door electronically during normal operation.In an emergency operation where opening cannot be achieved electronically, the handle element 4 is further rotated outward by a second user force, thereby pressing the head section 22 of the stop element 18 against the blocking rollers 50a and 50b via its sliding surface 25, overcoming the obstructing effect of the opposing stop element 26. Here, the blocking rollers 50a and 50b move away from each other in a translational manner, during which they rotate. The movement of the blocking rollers 50a and 50b is against the force of the mechanical reset element 41. If the obstruction is overcome, the user can move the handle element 4 to the emergency actuation position with less force to open it mechanically. In the movement from the emergency actuation position back to the rest position, the head section 22 of the stop element 16 is positioned outside the gap 28 via the profile surface 55. The surfaces of the blocking rolling elements 50a and 50b that contact the head section 22 are configured as cylindrical when the handle element 4 moves from the rest position to the emergency actuation position, and as conical when the handle element 4 contacts the head section 22 from the emergency actuation position to the rest position.

[0056] exist Figures 29 to 33 The diagram illustrates a fourth embodiment of the door handle assembly 3 according to the invention, wherein the opposing stop element 26 has two blocking elements 30a, 30b and a support housing 56 fastened to or constructed integrally with the handle bracket 9, the support housing being similar to the housing 40 of the second embodiment. The two blocking elements 30a, 30b are movably supported on the support housing 56 such that the two blocking elements 30a, 30b are supported so that they can move toward each other to reduce the gap 28 and move away from each other to increase the gap 28, as in the three embodiments described above, and referring to the preceding description, for example, the second embodiment. Figure 22 In the fourth embodiment, the corresponding blocking elements 30a and 30b are configured as blocking plates 39a and 39b supported in a displaceable manner, as in the second embodiment. The corresponding blocking plates 39a and 30b have blocking sections 45 and supporting sections 47, wherein the corresponding supporting sections 47 are supported in a manner pivotable on a supporting shaft 44 formed on a supporting housing 56. The corresponding blocking sections 45 are constructed according to the type of plate, wherein gaps 28 are formed between the two blocking sections 45 and on the adjacent edges of the blocking plates 39a and 39b, for example, in the second embodiment. Figure 22 As already shown and described with reference to the accompanying drawings, the description therein also applies to the fourth embodiment. The features of the fourth embodiment can be transferred not only to the second embodiment, but also to the first and third embodiments, and can be combined accordingly with the features therein. Figure 29 The image shows the opposing stop element 26 in its assembled state, while... Figure 30A single-part drawing of the opposing stop element 26 is shown, and the stop element 18 is also shown additionally. As in the second embodiment, the corresponding stop plates 39a and 39b in the fourth embodiment also have a stop section 45 and a support section 46, as shown by... Figure 30 As seen, the corresponding support section 46 here has an arc-shaped support edge 47, wherein the arc-shaped support edges 47 of the two blocking pieces 39a, 39b are configured with different radii, such that the support edge 47 of one blocking piece 39a is supported within the support edge 47 of the other blocking piece 39b and the support edges 47 are supported in a manner that allows them to rotate relative to each other. In the fourth embodiment, the opposing stop element 26 also has a mechanical reset element 41, which corresponds to the mechanical reset element of the second embodiment and the mechanical reset elements 34 and 52 of the other two embodiments, and is also configured as a torsion spring 42. The two blocking elements 30a and 30b are connected to the mechanical reset element 41 as in the other three embodiments. In particular, the two blocking elements 30a and 30b are supported so that they can move from the blocking position to the release position within the support housing 56 against the force of the mechanical reset element 41. The mechanical reset element 41, as in the other three embodiments, also has a first spring arm 36a and a second spring arm 36b, wherein the first spring arm 36a is supported on one of the two blocking elements 30a, and the second spring arm 36b is supported on the other of the two blocking elements 30b. The fourth embodiment features an insert element 57 on the opposing stop element 26. The insert element 57 is configured in a butterfly shape, wherein two motion limiting plates 59 prevent movement of the blocking elements 30a, 30b. Furthermore, the motion limiting plates 59 are configured to guide the movement of the two blocking elements 30a, 30b as they pivot. The insert element 57 is arranged on the support housing 56 and configured to at least partially retain the first spring arm 36a and the second spring arm 36b. Retention of the two spring arms 36a and 36b is achieved by a guide 31, which in the fourth embodiment is formed on the insert element 57 and is also designed as a cylindrical shape. For example, from... Figure 29 , Figure 31 , Figure 32 and Figure 33As can be observed, the free ends of the two spring arms 36a and 36b are partially housed in guides 31, wherein each spring arm 36a and 36b has a guide 31 assigned to and therefore belonging to itself. Each guide 31 forms an end stop 58, against which the corresponding spring arm 36a, 36b abuts in the blocking position of the opposing stop element 26. To move from the blocking position to the release position, the spring arms 36a and 36b are held in a guided manner within the guides 31, wherein the guides 31 of the embedded element 57 are configured to center the spring arms 36a and 36b in at least two spatial directions. Thus, the embedded element 57 is configured to have guides 31 in which the first spring arm 36a and the second spring arm 36b are at least partially arranged, wherein the guides 31 are configured to oriented and guided the first spring arm 36a and the second spring arm during the movement of the two blocking elements 30a, 30b. For example, by Figure 33 As can be seen, the guide 31 of the embedded element 57 is shown partially cut out, and the corresponding guide 31 supports the assigned spring arms 36a or 36b in the horizontal and / or vertical directions relative to the assembled state of the door handle assembly 3, wherein the embedded element 57 additionally centers the two spring arms 36a and 36b in at least two spatial directions. The embedded element 57 is made of high-strength steel. Therefore, it is possible that the support housing 56 can be made of plastic and thus manufactured cost-effectively through injection molding. It should be understood that the design of the fourth embodiment can also be adapted to other embodiments, wherein the corresponding blocking elements 30a, 30b are configured as blocking rollers 50a, 50b supported in a displaceable manner.

[0057] The door handle assembly 3 according to the invention has a handle element 4 configured as a folding handle, wherein electronic actuation of the door lock 5 is triggered by a microswitch 10 during normal operation, the microswitch responding when the handle element 4 makes a pivoting movement of approximately 5°. To ensure actuation of the door handle assembly 3 even in the event of electronic component failure or power loss, a mechanical actuation method for unlocking is provided, wherein the handle element 4, configured as a folding handle, pivots up to approximately 30° beyond the normal actuation pivoting movement. Between these actuation positions, an overcoming obstruction is provided, which forms a noticeably perceptible mechanical stop for normal actuation and allows for further deflection of the handle element 4 when the force is increased. For this purpose, the handle element 4 is mechanically equipped with a spring-loaded stop element 18 having an extended neck section 21 and a thickened head section 22 having a laterally inclined sliding surface 25. The stop element 18 can therefore pivot relative to the handle element 4 against the spring force. In the normal state, the stop element 18 extends through the gap 28 between the two movable blocking elements 30a and 30b, with its neck-shaped section 21. These two movable blocking elements 30a and 30b are held in the guide 31 so that they can move toward each other to narrow the gap 28 and away from each other to widen the gap 28. The two blocking elements 30a and 30b are held in a blocking position by springs 34, 41, or 52, each secured to one of the blocking elements by an arm, in which the gap 28 is large enough for the neck-shaped section 21 of the stop element 18 but too small for the head section 22 of the stop element 18. Only under sufficient force can the stop element 18 overcome the spring force of springs 34, 43, or 52 through its external shape and the corresponding shapes of the blocking elements 30a and 30b, thus widening the gap 28 between the blocking elements 30a and 30b, allowing the head section 22 of the stop element 18 to slide through between the blocking elements 30a and 30b. This process highlights the transition from normal electronic actuation (where the head section 22 remains on the same side of the blocking elements 30a and 30b) to emergency mechanical actuation, in which the handle element 4 is pulled by a certain force, which causes the blocking elements 30a and 30b to be pried open, allowing the head section 22 to slide through between the blocking elements 30a and 30b. Once the head section 22 of the stop element 18 has slid through between the blocking elements 30a and 30b, the blocking elements 30a and 30b return to their initial position, i.e., to the blocking position, due to their prestress. In order to reset the handle element 4 after mechanical actuation, a contour portion 29 with blocking elements 30a and 30b is provided, so that during the return movement of the handle element 4, the handle element 4 pivots against its prestress by contacting the contour portion 29 and is guided to below the blocking elements 30a and 30b. The head section 22 passes under the blocking elements 30a and 30b and is guided to their rear.In this position (where the head segment 22 is again behind the blocking elements 30a and 30b), the stop element 18 can pivot back to its initial position according to its prestress, wherein the neck segment 21 moves into the gap 28 between the blocking elements 30a and 30b. The blocking elements 30a and 30b do not move here; only the stop element 18 moves.
