Description

The invention is directed to a door handle arrangement of a motor vehicle, comprising a handle holder, a handle which can be moved into a rest position and a handling position, and a restoring element which biases the handle in the direction of the handle holder, the handle being flush with the outside of the when installed in a vehicle door in the rest position Vehicle door is arranged running and in the handling position for actuation relative to the outside of the vehicle door in an opening direction is arranged, and wherein for actuation the handle is designed to be relatively movable from its handling position into an actuation position for an electrical opening of a door lock to the handle holder.

Such a door handle arrangement is, for example, from DE 10 2013 212 198 A1 known and has a handle which is arranged flush in its rest position and which can be moved by a motor from the rest position into a handling position. Such a handle is preferably used in electric cars in which the handle extends exclusively with a power-operated drive from its flush or flush rest position, in which the handle is arranged to reduce air resistance, into the handling position when a legitimate operator approaches the motor vehicle . As soon as the handle is no longer needed, it returns to its rest position and disappears into the body so as not to create any air resistance. The disadvantage is that the handle can no longer be moved if the motor drive fails and opening a door is almost impossible, which is quite problematic for safety reasons.

In this regard, a door handle arrangement is known in which at the end of a first actuation path of a manually operated handle body, a resistance device comes into effect, which increases the actuation resistance, so that a switch for electrically opening the door lock is only actuated after or when a noticeable pressure point is overcome and the door lock is actuated electrically opens. If the handle is deflected beyond the first actuation path along a second actuation path, the door lock is opened mechanically in an emergency, such as in the case of an empty vehicle battery, which requires an actuation force that is greater than the force required for electrical opening is necessary. Due to the construction of this known door handle arrangement, an increased actuation force of the handle body is required for normal operation of the door handle arrangement in order to reach or overcome the pressure point and to open a door lock electrically, which disadvantageously limits the comfort of the door handle arrangement.

A door handle arrangement according to the preamble of claim 1 is from the document WO 2018/137819 known .

The invention is based on the object of creating a solution which provides an improved door handle arrangement in a structurally simple manner, through which the above-mentioned disadvantages are avoided and through which comfortable handling of a handle for the operator is possible.

This object is achieved according to the invention by a door handle arrangement of a motor vehicle with the features according to claim 1.

The door handle arrangement of a motor vehicle according to the invention has an electro-mechanical locking system with a door lock, a handle holder, a handle which can be moved into a rest position and a handling position, and a restoring element which biases the handle in the direction of the handle holder. When installed in a vehicle door, the handle is arranged to run flush with the outside of the vehicle door in the rest position and is in the handling position Actuation arranged opposite the outside of the vehicle door in an opening direction. For actuation, the handle is designed to be relatively movable from its handling position into an actuation position for an electrical opening of the door lock or into an emergency actuation position that extends beyond the actuation position for a mechanical opening of the door lock to the handle holder. The handle is further coupled to the handle holder for movement via a first connecting device and a second connecting device. The first connection device and the second connection device are arranged at a distance from one another. A resistance device is arranged within the first and/or second connecting device, which generates a resistance force that counteracts the actuation when the handle is actuated from the actuation position into the emergency actuation position. The resistance force for operating the handle from the operating position into the emergency operating position is greater than the force to be applied by an operator of the door handle arrangement to operate the handle from the handling position into the operating position.

Advantageous and expedient refinements and developments of the invention result from the subclaims.

The invention provides a door handle arrangement which is characterized by a simple construction. In the door handle arrangement according to the invention, a door lock of the door of the motor vehicle is already opened electrically with a normal actuation force, the normal actuation force having to be greater than the restoring force generated by the restoring element. The door lock can therefore be opened electrically with minimal effort. According to the invention, the resistance device generating the resistance force is only effective when the handle is moved from the operating position into the emergency operating position, the force for moving the handle from the handling position into the operating position being smaller than the resistance force and being generated exclusively by the restoring element. In this way, the operator of the door handle arrangement receives noticeable feedback that the force used to operate the handle is sufficient for electrical opening. If the door lock is then not opened electrically, which can be the case, for example, with an empty car battery and requires emergency operation, the operator can apply an increased actuation force, which is greater than the resistance force, in order to open the door lock mechanically. The door lock is then opened purely mechanically, for example with the help of a Bowden cable coupled to the handle, which in turn is coupled to the door lock. The handle is biased into its handling position by means of a restoring element designed, for example, in the manner of a spring, so that after the operator has applied an actuating force, the handle strives to return to its handling position. For a movement of the handle from the operating position or emergency operating position into the handling position, the restoring element can be dimensioned with a small restoring force, because when the handle moves back into the handling position, the resistance device does not generate any force worth mentioning that counteracts the restoring force.

The invention preferably provides in the design of the door handle arrangement that the handle holder is movably mounted on a handle support between a rest position and a working position, the handle being arranged in its rest position in the rest position of the handle holder and the handle being in its rest position in the working position of the handle holder Handling position is arranged. When moving the handle bracket out of the Rest position to the working position, the handle remains stationary on the handle holder, but during this movement of the handle holder the handle is moved relative to the vehicle door and thereby from the rest position into the handling position. Because the handle is mounted on the handle holder and is moved into the handling position with the help of the handle holder without being moved relative to the handle holder, the use of a complex and space-consuming lever mechanism for extending the handle is unnecessary. Rather, as an alternative to lever concepts, other options for extending the handle out of the door can be considered.

To operate the handle in its handling position, it is provided according to the invention that the first connecting device has a pivot axis and the second connecting device has a lever mechanism, the handle being rotatably connected to the handle holder via the pivot axis and the handle being connected to the handle holder via the lever mechanism and the second connecting device is rotatable relative to the pivot axis. With the help of this embodiment according to the invention, a pivoting movement of the handle for actuation is realized.

For a compact construction of the door handle arrangement according to the invention, it is provided that the first connecting device has a connecting web which extends from the handle holder in the direction of the handle and on which the pivot axis is mounted, the connecting web being arranged inserted into a receiving space formed on the handle, wherein the second connecting device has a hollow connection projection which extends from the handle holder in the direction of the handle and in which the lever mechanism is accommodated, and wherein the connection projection is inserted into a receiving chamber formed on the handle. The recording space and the recording chamber protect the The components required to operate the handle are protected from contamination and environmental influences and encapsulate these components accordingly.

For a powerless emergency operation of the door handle arrangement according to the invention, the invention provides in a further advantageous embodiment that the pivot axis is mounted on the connecting web so that it can move against a force of an emergency spring element in a direction pointing away from the handle. The handle is thus designed to be depressible on the first connecting device in the direction of the handle holder, so that in a de-energized emergency operation, the handle is pressed in on the first connecting device, whereby the handle is arranged on the second connecting device and can be grasped by an operator in order to insert the handle to move their handling position, from which the handle can then be moved by the operator via the actuation position into the emergency actuation position in order to cause a mechanical opening of the door lock.

A further embodiment not according to the invention provides that the resistance device is arranged on the second connecting device and has a leaf spring and a force-increasing surface formed on the handle holder, the leaf spring being mounted on a wall of the receiving chamber. The leaf spring and the force increasing surface are designed in such a way that they interact and generate the resistance force at the latest when the handle is arranged in its operating position.

It is structurally particularly favorable for the embodiment not according to the invention described above if a free end of the leaf spring extends from the wall inwards of the receiving chamber and the force-increasing surface is formed on the connecting shoulder, with the free end of the leaf spring facing the force-increasing surface in the handling position of the handle is arranged at a distance, and when the Handle from the handling position in the direction of the actuation position, the free end of the leaf spring moves in the direction of the force increasing surface. This embodiment advantageously exploits the fact that when the handle is actuated from the handling position, the receiving chamber moves relative to the handle holder.

This circumstance is also advantageously exploited in a further embodiment of the embodiment not according to the invention described above in that in the actuating position of the handle, the free end of the leaf spring rests on a force increasing ramp of the force increasing surface which is inclined in the direction of the wall of the receiving chamber, with a movement of the handle in the Emergency actuation position, the handle moves the free end of the leaf spring along the force increase ramp up to a friction force surface running parallel to the wall of the receiving chamber against the resistance force, which corresponds to a sum of a restoring force generated by the restoring element and a counterforce generated by the leaf spring. In this embodiment, the operator must therefore apply a force that exceeds the normal actuation force in order to effect a mechanical emergency opening, the force to be used for this must be greater than the sum of the restoring force generated by the restoring element and the counterforce generated by the leaf spring.

In another embodiment not according to the invention, the resistance device is arranged on the first connecting device and the resistance device has a torsion spring with a first spring leg and a second spring leg and a force increasing surface formed on the handle, the torsion spring being mounted on the pivot axis.

In order to use the relative mobility of the handle relative to the handle holder in a structurally simple manner, in a further embodiment of the other embodiment, which is not according to the invention, it is provided that the first spring leg protrudes from the connecting web, whereby in the handling position of the handle, the connecting web supports the first spring leg and the first spring leg is arranged at a distance from the force increasing surface, and wherein when the handle moves from the handling position in the direction of the actuation position, the force increasing surface moves in the direction of the first spring leg. The handle consequently moves the force increasing surface formed on it towards the first spring leg, with the second spring leg remaining supported on the connecting web, even if an operator moves the handle. Due to the spacing of the first spring leg and the force increasing surface in the handling position, when the handle is normally actuated, only the restoring force of the restoring element, which the operator has to overcome when operating the handle, acts for an electrical opening process.

In a further embodiment of the other embodiment, which is not according to the invention, it is provided that the door handle arrangement is designed in such a way that in the operating position of the handle, the first spring leg rests on the force increasing surface, with the force increasing surface moving the first spring leg in the direction when the handle is moved into the emergency actuation position of the second spring leg against the resistance force, which corresponds to a sum of a restoring force generated by the restoring element and a counterforce generated by the torsion spring. During emergency operation, the operator must therefore apply a noticeably higher force to actuate the handle in order to move it into the emergency actuation position for mechanical opening.

The invention provides that the resistance device is arranged on the second connection device, the resistance device having a force-increasing surface arranged on the handle holder and within the connection attachment and a force-increasing surface formed on the lever mechanism and used to generate the Resistance force has a stop surface that interacts with the force increasing surface.

It is structurally particularly advantageous in the embodiment of yet another embodiment if, in the handling position of the handle, the stop surface is arranged at a distance from the force-increasing surface, with the stop surface moving in the direction of the force-increasing surface when the handle moves from the handling position in the direction of the actuation position. Due to the distance that exists in the handling position between the stop surface and the force increasing surface, when the handle is normally actuated, only the restoring force of the restoring element, which the operator has to overcome when operating the handle, acts for an electrical opening process.

In order to give the operator of the door handle arrangement the noticeable feeling of a stop when the handle has reached the operating position for electrical opening and thus a kind of end position in a normal opening process, another advantageous embodiment provides that the force increasing surface on the handle holder is between a base position and an emergency position is pivotally mounted, wherein in the actuating position of the handle the stop surface rests on the force increasing surface arranged in the base position and the force increasing surface is arranged lying between the stop surface and the handle, and for a movement of the handle out of the actuating position in In the direction of the emergency actuation position, the stop surface pivots the force-increasing surface against the force of an elasticity element from the base position into the emergency position, in which the force-increasing surface is arranged outside of a movement path of the stop surface. Due to the pivotability of the force increasing surface, which is pivoted out of the movement path of the stop surface when the force is sufficiently high the operator has the noticeable feeling that a force threshold has to be overcome for emergency operation in order to carry out a mechanical emergency opening. Because if the force increasing surface is arranged to be pivoted out of the movement path of the stop surface, only the restoring force of the restoring element acts, which the operator has to overcome in order to move the handle into the emergency actuation position.

An advantageous, structurally simple and cost-effective way to realize the elasticity element is that the elasticity element is a foam part that pushes the force-increasing surface in the direction of its base position.

Due to the elasticity, it is possible in the embodiment of yet another advantageous embodiment for the elasticity element to push the force-increasing surface back into the base position when the handle moves out of the actuation position in the direction of the emergency actuation position and the stop surface is arranged between the force-increasing surface and the handle.

It is structurally particularly flexible in the embodiment of yet another advantageous embodiment if the lever mechanism has a main lever connecting the handle holder with the handle and a force increasing lever, which is rotatably mounted on the main lever and which has the stop surface.

In another advantageous embodiment, it is provided that the force increasing lever is designed with two arms and has a first lever arm and a second lever arm, the first lever arm of the force increasing lever having the stop surface.

Furthermore, in another advantageous embodiment it is provided that a blocking surface is formed on the main lever, which blocks rotation of the first lever arm in the direction of the force increasing surface. The blocking surface can block a rotation of either the first lever arm or the second lever arm, and also blocking of the second lever arm in one direction of rotation blocks a rotation of the first lever arm in the corresponding direction of rotation.

Furthermore, in the embodiment of yet another advantageous embodiment, it is advantageous if a retaining surface is formed on the force-increasing surface, which in the base position rests on a retaining projection formed on the handle holder, which blocks pivoting of the force-increasing surface in a direction opposite to the emergency position. In this way, when the handle is reset, the force increasing surface remains unchanged in the starting position and is not twisted by the stop surface.

It is structurally particularly favorable in the embodiment of a further embodiment not according to the invention if the resistance device is arranged on the second connecting device and has a retaining lever arranged on the handle holder, which is designed at its free end with a retaining hook, and a blocking approach formed within the connecting lug , wherein the blocking approach extends into a movement path of the retaining hook of the retaining lever.

For the further embodiment not according to the invention, it is provided in an embodiment that in the rest position of the handle, the retaining hook and the blocking approach are arranged at a distance from one another, and the retaining lever extends over the blocking approach. When the handle moves out of the rest position, the retaining hook and the blocking approach come closer together.

In a further embodiment of the further embodiment not according to the invention, it is provided that the retaining lever is pivotally mounted on the handle holder against a restoring force of a spring element. The pivotable mounting allows the retaining lever to be pivoted in such a way that the retaining hook can overcome the blocking approach arranged in its path of movement.

For the further embodiment not according to the invention, it is then provided in an embodiment that in the actuating position of the handle for electrically opening the door lock, the retaining hook is arranged behind the blocking approach.

If electrical opening is not possible, the further embodiment not according to the invention provides that when the handle is moved from the operating position to the emergency operating position, the retaining hook is designed to move over the blocking approach as a result of pivoting the retaining lever against the retaining force of the spring element . This allows the handle to be pivoted to such an extent that the door lock can be opened mechanically.

So that the door handle arrangement can be returned to a normal starting position for normal operation even after emergency operation, it is finally provided in the further embodiment not according to the invention that the blocking approach has an oblique restoring surface, which is on a side of the blocking approach facing the spring element is trained.

It is understood that the features mentioned above and to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention. The scope of the invention is defined only by the claims.

In Figure 1 a motor vehicle 1 is shown as an example in the form of a car, which in the example has four vehicle doors 2 (two of which are made of Figure 1 can be seen), which can be opened via a respective door handle arrangement 3 and in particular with the help of a handle 4 of the door handle arrangement 3. The vehicle doors 2 are tightly closed via a respective door lock 5 and can be opened from the outside via a respective movement of the handle 4. In normal operation of the door handle arrangement 3, this movement on the handle 4 consists of a pulling movement, which is recognized, for example, by a micro button, whereupon the door lock 5 of the vehicle door 2 is opened electrically. By moving the handle 4 accordingly, the associated vehicle door 2 can then be opened. For the purposes of the invention, normal operation is to be understood as an operating mode of the door handle arrangement in which the locking and unlocking of vehicle doors (and also flaps) takes place purely electrically by means of a drive unit, the handle 4 also being moved electrically from a rest position to a handling position which an operator can reach behind and operate the handle 4 to open the vehicle door 2. For electrical opening during normal operation of the door handle arrangement 3, the operator then moves the handle 4 from the handling position into an actuation position, whereby the handle 4 is pivoted to a certain extent and a switch is actuated, which in turn activates an electro-mechanical locking system 14 , with the help of which the door lock 5 can then be opened (see Figure 6 ). The door handle arrangement 3 is also designed for a powerless emergency operation in which the vehicle electronics have failed (for example in the event of an empty vehicle battery) and the handle 4 must first be moved manually by an operator into the handling position in order to unlock and open the vehicle door 2 4 accordingly operate, whereby the handle 4 must be moved into an emergency actuation position, which is a movement beyond the actuation position for electrical opening.

The Figure 2 shows a perspective view of one of the vehicle doors 2 and the handle 4 used to open the vehicle door 2. In the Figure 2 the handle 4 - when installing the door handle arrangement 3 in the vehicle door 2 - is arranged approximately flush with the outside 6 of the vehicle door 2, ie flush or flush with the surface. In this position, the handle 4 is in a rest position in which it is not used. It should be noted that the present invention is not limited to handles 4, which are arranged flush or flush with the surface in their rest position. Rather, the invention additionally includes embodiments in which the handle 4 is arranged to be exposed relative to the outside 6 of the vehicle door 2 in such a way that the handle 4 cannot be actuated or handled by an operator because the handle 4 is in this position by one Operator cannot be attacked. From the in Figure 2 In the rest position shown, the handle 4 is in an in Figure 3 shown handling position can be transferred, in which it protrudes from the outside 6 of the vehicle door 2 and is arranged to be displayed in comparison to its rest position. Accordingly, the handle 4 is arranged to protrude from the vehicle door 2 in its handling position. In this protruding handling position or extended from the outside 6, an operator can reach behind the handle 4 and operate or handle it in order to open the vehicle door 2. The handle 4 can be transferred from the rest position to the handling position by means of a mechanical actuating element, which is moved by a drive motor during normal operation. Proximity sensors or other sensors can be provided for normal operation in order to put the drive motor into operation and thereby move the actuating element so that the Handle 4 is brought from the rest position into the handling position as soon as an operator approaches the door handle arrangement 3 or the handle 4. For this purpose, proximity sensors known from the prior art can be installed in the handle 4, which, when an authorized operator or ID transmitter is detected, send a signal to a vehicle control device, whereby the drive motor is put into operation and for the issuance of the handle 4 the handling position ensures. In the embodiment shown in the figures, the handle 4 can be pushed inward by an operator, thereby actuating a handle release pushbutton unit 12 which is in Figure 11 is shown and which is coupled to the drive motor in such a way that the drive motor is put into operation in normal operation of the door handle arrangement 3 with the handle 4 pressed in and the handle 4 moves from the rest position into the handling position.

The door handle arrangement 3 according to the invention includes the handle 4 and a handle holder 7 (see for example the Figures 4, 5 and 7 ), whereby the handle 4 is motion-coupled to the handle holder 7. In the sense of the invention, a movement coupling is to be understood as meaning that, for example, a movement of the handle holder 7 has an effect on the handle 4, in that the handle 4 is moved, for example, with the handle holder 7, although the handle 4 moves relative to the movement of the handle holder 7 to the handle holder 7 remains stationary on the handle holder 7. This is exemplary for the door handle arrangement 3 according to the invention in the Figures 4 and 5 shown, in which the handle holder 7 is movably mounted on a handle carrier 8 which can be attached to the inside of the vehicle door 2, the handle carrier 8 being fixed in place on the vehicle door 2. In the Figures 2 and 3 the handle support 8 can be seen behind the outside 6 of the vehicle door 2, with the handle holder 7 between a rest position (see Figures 2 and 4 ) and a working position (see Figures 3 and 5 ) on the handlebar 8 is movably mounted. If the handle holder 7 is driven by a motor from the rest position (see Figure 4 ) into the working position (see Figure 5 ) is moved, the handle 4 is also moved due to the movement coupling of the handle 4 and the handle holder 7. Accordingly, it results that in the rest position of the handle holder 7, the handle 4 is arranged in its rest position (see Figures 2 and 4 ), whereas in the working position of the handle holder 7, the handle 4 is arranged in its handling position (see Figures 3 and 5 ). The Figures 4 and 5 show quasi-transparent views of the door handle arrangement 3, whereby the different positions of the components mentioned are particularly clearly visible. It should be noted that for the invention the handle carrier 8 represents a purely optional component, because the handle holder 7 could also be attached directly to the vehicle door 2 via appropriate movement levers, so that a handle carrier 8 can be dispensed with. The only important thing for the invention is that the handle 4 is motion-coupled to the handle holder 7, so that the handle 4 is moved into the working position when the handle holder 7 moves and thereby assumes its handling position without the handle 4 moving relative to the handle holder 7 moves. Accordingly, when the handle holder 7 moves from the rest position to the working position, the handle 4 is arranged on the handle holder 7 without moving, the handle holder 7 thereby moving the handle 4 from the rest position into the handling position in relation to the vehicle door 2. The movement of the handle holder 7 and the handle 4 takes place in an extension direction 9 directed transversely to the handle holder 7, for example from the Figures 4 and 5 is visible. As noted above, the handle support 8 is a purely optional component, which is why this component will no longer be discussed in the description below. The above description serves only as a general explanation of a possible Mode of operation of the door handle arrangement 3 and defines the arrangements of the handle 4 and handle holder 7.

In the Figures 7 to 11 the general structure of the door handle arrangement 3 according to the invention is shown, which applies to all embodiments to be described below, with a representation of the electro-mechanical locking system 14 being omitted for reasons of clarity. Like that Figures 7 to 11 As can be seen, the door handle arrangement 3 has the handle holder 7 and the handle 4, the handle 4 being movable from the rest position into the handling position. A restoring element 10 (see for example Figures 9 and 11 ) serves to bias the handle 4 against the opening direction 9. The restoring element 10 consequently pushes the handle 4 in the direction of the handle holder 7 in order to move the handle 4 back into the starting position, i.e. the handling position, for example after an operation by an operator. As already explained above, when installed in a vehicle door 2, the handle 4 is arranged to run flush with the outside 6 of the vehicle door 2 in the rest position, whereas the handle 4 in the handling position is for actuation relative to the outside 6 of the vehicle door 2 in an opening direction 9 is arranged issued. The opening movement of the handle 4 is realized by the handle holder 7, which is moved from the rest position to the working position, the handle 4 remaining stationary on the handle holder 7 during this movement. So that an operator can operate the handle 4 to open the door lock 5, the handle 4 is mounted on the handle holder 7 so that it can move relative to the handle holder 7. The handle 4 is coupled for movement to the handle holder 7 via a first connecting device 11 and via a second connecting device 15, as is shown, for example, in FIGS Figures 7 and 8th is shown. The first connecting device 11 and the second connecting device 15 are in a longitudinal direction 16 of the Door handle arrangement 3 arranged at a distance from one another. The first connecting device 11 and the second connecting device 15 are each designed like a peg, the distance between the two connecting devices 11 and 15 being dimensioned such that an operator can reach behind it in the handling position between the two connecting devices 11 and 15 to operate the handle 4 and the handle 4 can move in the direction of the opening direction 9.

The first connecting device 11 has a connecting web 17 and a receiving space 18, as can be seen, for example, in the sectional view of Figure 9 can be seen. The connecting web 17 extends from the handle holder 7 in the direction of the handle 4, with the receiving space 18 being formed on the handle 4, in which the connecting web 17 is arranged inserted in the assembled state of the door handle arrangement 3. The first connecting device 11 also has a pivot axis 19, which is arranged in the receiving space 18 and extends through the connecting web 17, so that the handle 4 is rotatably connected to the handle holder 7 via the pivot axis 19.

The second connecting device 15 has a connecting attachment 20, a lever mechanism 21 and a receiving chamber 22. The connecting projection 20 is hollow and extends from the handle holder 7 in the direction of the handle 4, with the lever mechanism 21 being accommodated within the connecting projection 20. When assembled, the connecting attachment 20 is inserted into the receiving chamber 22 formed on the handle 4. The restoring element 10 is also housed in the receiving chamber 22 and is supported on the handle holder 7 and on a main lever 23, the main lever 23 connecting the handle holder 7 and the handle 4 in an articulated manner. The restoring element 10 therefore acts on the Main lever 23 and exerts a restoring force on the main lever 23, which pushes the handle 4 towards its handling position.

By means of the pivot axis 19 of the first connecting device 11 and the lever mechanism 21 of the second connecting device 15, the handle 4 can be pivoted about the pivot axis 19 and is rotatable relative to the handle holder 7, so that the handle 4 can be moved out of its handling position into an operating position or into an above position Emergency operating position beyond the operating position can be moved. In order to move the handle 4 from the rest position into the handling position during a powerless emergency operation, the door handle arrangement 3 is designed such that the handle 4 can be pressed in by an operator against the opening direction 9, whereby the handle 4 is at the longitudinal end having the second connecting device 15 protrudes from the vehicle door and can be reached behind by the operator in order to move the handle 4 completely from its flush position in the vehicle door 2 into the handling position, in which the operator can then reach behind the handle 4 and operate it. For this purpose, the pivot axis 19 is mounted on the connecting web 17 so that it can move in a direction opposite to the extension direction 9 against a force of an emergency spring element 24, as shown in Figure 10 is shown as an example, wherein the lever mechanism 21 is further designed such that pressing in the handle 4 on the first connecting device 11 causes the handle 4 to move on the second connecting device 15 in the extension direction 9. This process is only intended for emergency operation, since in normal and power-operated operation of the door handle arrangement 3, pressing it in activates the handle release push-button unit 12, whereby a drive moves the handle holder 7 from the rest position to the operating position.

The door handle arrangement 3 according to the invention is designed in such a way that in normal and power-operated operation, the handle 4 can usually be operated by an operator, with the operator feeling an increased resistance force when the handle 4 reaches an operating position and the door lock 5 opens electrically, so that the operator is given the familiar feeling of a mechanical door opening. The actuation force required for this is very low, since the operator only has to overcome the restoring force of the restoring element 10. In the operating position of the handle 4, however, according to the invention, the resistance that the operator has to overcome increases, so that the operator has the impression that the pivoting movement of the handle 4 has reached an end stop and the handle 4 cannot be pivoted any further by the operator . According to the invention, however, the handle 4 can be moved or pivoted beyond the operating position into an emergency operating position, which can be the case, for example, in a de-energized emergency operation of the door handle arrangement 3 in order to open the door lock 5 mechanically. In order to move the handle 4 out of the actuation position in the direction of the emergency actuation position in a de-energized emergency operation, the operator must apply a force that is greater than a resistance force counteracting the actuation. This resistance force represents an actuation resistance for the operator, which either has to be overcome briefly for a movement of the handle 4 out of the actuation position in the direction of the emergency actuation position, so that the actuation can be carried out for the operator with less effort after overcoming the actuation resistance (the resistance then corresponds to a force threshold to be overcome), or which must be overcome until the handle 4 is arranged in the emergency actuation position (the resistance then corresponds to one up to increase in force to be overcome in the actuating position). This actuation resistance corresponds to the resistance force generated by a resistance device 25. The resistance device 25 only generates the resistance force that counteracts the actuation of the handle 4 when an operator moves the handle 4 from the actuation position into the emergency actuation position, which is the case for emergency operation. According to the invention, the resistance device 25 can be arranged within the first connection device 11, within the second connection device 15 or within the first and second connection devices 11 and 15, with the resistance device 25 being described below for different embodiments.

The Figures 12 to 24 refer to a first embodiment for the resistance device 25, which is arranged on the second connection device 15. The resistance device 25 has a force increasing surface 26, a stop surface 27 and an elasticity element 28. The force increasing surface 26, the stop surface 27 and the elasticity element 28 are arranged on the handle holder 7 and within the hollow connecting extension 20, the stop surface 27 being formed on the lever mechanism 21. As already described above, the lever mechanism 21 has the main lever 23, which connects the handle holder 7 to the handle 4. Furthermore, the lever mechanism 21 has a force increasing lever 29, on which the stop surface 27 is formed. The force increasing lever 29 is rotatably mounted on the main lever 23 about an axis of rotation 32 and has two arms with a first lever arm 30 and a second lever arm 31. The stop surface 27 is formed on the first lever arm 30 of the force increasing lever 29. A blocking surface 33 is also formed on the main lever 23, which carries the axis of rotation 32 which is designed to be movable with the main lever 23, with a retaining spring 34 is wound around the axis of rotation 32 (see Figures 12, 13 and 14 ). The retaining spring 34, which is designed as a torsion spring and whose spring arms are supported on the first lever arm 30 and on the force increasing lever 29 and the main lever 23, pushes the second lever arm 31 against the blocking surface 33, the blocking surface 33 preventing the force increasing lever 29 from rotating counterclockwise and thus blocks a rotation of the first lever arm 30 in the direction of the force increasing surface 26. The force increasing surface 26 is formed on a lever element 38, which is rotatably mounted on the handle holder 7 about an escape axis 35. A retaining surface 36 protrudes from the force increasing surface 26, which cooperates with a retaining projection 37 formed on the handle holder 7, the retaining projection 37 blocking rotation of the force increasing surface 26 in the clockwise direction. The force increasing surface 26 and the retaining surface 36 are therefore designed as respective lever arms of the lever element 38, the lever element 38 being rotatably mounted about the escape axis 35. The lever element 38, together with the elasticity element 28, generates the resistance force, which becomes effective when the operator wants to move the handle 4 beyond the actuation position in the direction of the emergency actuation position, which will be discussed below with reference to Figures 17 to 24 will be discussed in more detail.

In the Figures 17 and 18 the handle 4 is arranged in its handling position and can be reached behind by an operator in order to move the handle 4 even further into the opening direction 9 on the second connecting device 15. As can be seen from the detailed view of the Figure 18 As can be seen, in the handling position of the handle 4, the stop surface 27 is arranged at a distance from the force increasing surface 26. If an operator now operates the handle 4 and pulls it, the handle 4 moves on the second connecting device 15 in the extension direction 9, whereby the Handle 4 is pivoted about the pivot axis 19, as shown in the Figures 19 and 20 is shown. In the Figures 19 and 20 the handle 4 is arranged in its operating position, which can be detected by the door handle arrangement 3 via a button and/or a microswitch, so that an electrical opening of the door lock 5 can be initiated. To reach the operating position, the handle 4 is pivoted through an angle about the pivot axis 19, which is between 3° and 4°. When the handle 4 moves from the handling position in the direction of the actuation position, the stop surface 27 moves in the direction of the force increasing surface 26, with the stop surface 27 resting against the force increasing surface 26 in the actuating position of the handle 4 and the force increasing surface 26 between the stop surface 27 and the handle 4 is arranged lying down, as shown in Figure 20 is shown. In this position, the force increasing surface 26 is arranged in a base position. The elasticity element 28 is uncompressed in the base position and presses against the lever arm of the lever element 38 which has the force increasing surface 26, the elasticity element 28 further pressing the retaining surface 36 formed on the other lever arm of the lever element 38 against the retaining projection 37 formed on the handle holder 7. In the operating position of the handle 4, the operator experiences a noticeable resistance force, which is generated by the resistance device 25, and which he perceives as a kind of stop, since a movement of the handle 4 beyond the operating position is no longer possible with the force previously applied. However, since in normal operation the door lock 5 is already opened electrically at this point in time, the operator perceives the actuation position as the end position, in particular because the opening process has been initiated or completed. The actuation force that the operator must apply to reach the actuation position must be slightly greater than the restoring force of the restoring element 10, since the restoring force of the restoring element 10 is the only resistance that the operator has to overcome when moving the handle 4 from the handling position into the operating position. Accordingly, the stop surface 27 interacts with the force increasing surface 26 to generate the resistance force.

A powerless emergency operation, in which the door lock 5 is opened mechanically by actuating the handle 4 (the handle 4 can be mechanically connected to the door lock 5 via a Bowden cable, for example), is in the Figures 21 to 23 shown, with the handle 4 in the Figures 23 and 24 is arranged in its emergency operating position, in which the door lock 5 is opened mechanically, whereas the Figures 21 and 22 show an intermediate position in which the handle 4 is arranged in a position between the operating position and the emergency operating position. If the handle 4 is moved beyond the actuation position in the direction of the emergency actuation position by a user, then the stop surface 27 pivots the force increasing surface 26 against a force of the elasticity element 28, the force increasing surface 26 of the lever element 38 being rotated counterclockwise about the escape axis 35 and from the basic position (see Figure 20 ) into an emergency position (see Figure 22 ) is pivoted, in which the force increasing surface 26 is arranged lying outside a movement path of the stop surface 27. The resulting compression of the elasticity element 28 generates a counterforce which, together with the restoring force of the restoring element 10, represents the resistance force to be overcome by the user until the force increasing surface 26 is rotated outside the movement path of the stop surface 27. Only then does the resistance for the user decrease and the user can then use the handle 4 with a smaller actuation force than this resistance force Deflect the emergency actuation position to open the door lock 5 mechanically. To overcome the resistance force, the handle 4 must be pivoted from the operating position in the direction of the emergency operating position by 1° to 2° about the pivot axis 19. The elasticity element 28 can, for example, be a foam part that pushes the force increasing surface 26 towards its base position. After overcoming this resistance, which is noticeable to the operator as a force threshold, the elasticity element 28 pushes the force-increasing surface 26 back into the base position when the handle 4 moves out of the actuation position in the direction of the emergency actuation position and the stop surface 27 between the force-increasing surface 26 and the handle 4 is arranged. In the emergency actuation position (see Figures 23 and 24 ), the elasticity element 28 is uncompressed and pushes the lever arm of the lever element 38, which has the retaining surface 36, against the retaining projection 37 formed on the handle holder 7, which blocks pivoting of the force increasing surface 26 in a direction opposite to the emergency position. When moving the handle 4 from the operating position into the emergency operating position, the blocking surface 33 formed on the main lever 23 blocks the first lever arm 30 of the force increasing lever 29 from rotating counterclockwise, so that the stop surface 27 is arranged aligned with the force increasing surface 26 and the Stop surface 27 and the force increasing surface 26 rest against each other in a wedge shape in the operating position of the handle 4. When the handle 4 is returned to the handling position after an emergency actuation, the restoring force of the restoring element 10 correspondingly pushes the handle 4 in a direction opposite to the opening direction 9. The force increasing lever 29 comes into contact with the lever arm of the lever element 38 which has the force increasing surface 26, the lever element 38 moving the force increasing lever 29 in a clockwise direction rotates so that the second lever arm 31 is arranged at a distance from the blocking surface 33 and the first lever arm 30 avoids the force increasing surface 26 so that the handle 4 can return to its handling position.

The Figure 25 shows a resistance-pivot angle diagram, which shows a resistance W to be overcome to operate the handle 4 of the door handle arrangement 3 as a function of the pivot angle α of the handle 4 about the pivot axis 19. During current-operated normal operation of the door handle arrangement 3, the operator only has to overcome the restoring force of the restoring element 10 in order to move the handle 4 into the actuating position (corresponds to in Figure 25 to move to point A). The operator must do this in Figure 25 Overcome the course of resistance shown with B in order to reach point A, i.e. the operating position of the handle 4. This actuation is identical for all three embodiments for normal current-operated operation. If there is a powerless emergency operation, the operator must move the handle 4 beyond point A to point C, in which the handle 4 is arranged in the emergency operation position. It is characteristic of the two embodiments described below that when the handle 4 moves out of the operating position A in the direction of the emergency operating position C, an increase in force D is necessary to operate the handle 4, which continues to increase linearly until the emergency operating position is reached, as the straight line E in Figure 25 can be seen. In contrast, in the first embodiment described above, a "force threshold" for the operator only has to be overcome at point A, the actuation position, as has already been described previously. This in Figure 25 The diagram shown is representative of the following two embodiments, in which the operator for an emergency operation from the actuation position until it is reached the emergency actuation position must use a force that exceeds the resistance force. Thus, for the two embodiments described below, there is an "increase in force" which the operator must overcome from the actuation position until the emergency actuation position is reached in order to actuate the handle 4 for mechanical opening in a de-energized emergency operation.

The Figures 26 to 28 refer to a second embodiment for the resistance device 25, which in turn is also arranged on the second connecting device 15. The resistance device 25 has the force increasing surface 26, which is formed on the handle holder 7 in this embodiment, and a leaf spring 39. The leaf spring 39 is mounted on a wall 40 of the receiving chamber 22 of the handle 4, for example Figure 26 is visible. The leaf spring 39 has a strip-shaped base body 41, which rests on the wall 40 of the receiving chamber 22 and is attached to the wall 40. A longitudinal end of the leaf spring 39 projects from the base body 41 and represents a free end 42 of the leaf spring 39. The free end 42 of the leaf spring 39 extends from the wall 40 inwards of the receiving chamber 22. More precisely, the free end 42 is the leaf spring 39 formed arcuately, with the arcuately formed, free end 42 extending into the interior of the receiving chamber 22. In the second embodiment, the force increasing surface 26 is formed on the connecting shoulder 20 of the handle holder 7, with the handle 4 in the handling position (see Figure 27 ) the free end 42 of the leaf spring 39 is arranged at a distance from the force increasing surface 26. When the handle 4 moves from the handling position in the direction of the actuation position, the free end 42 of the leaf spring 39 moves in the direction of the force increasing surface 26 until the free end 42 of the leaf spring 39 is in the actuation position (see Figure 28 ) at the Force increasing surface 26 is applied. The force increasing surface 26 is formed with a force increasing ramp 43 that runs obliquely and is inclined in the direction of the wall of the receiving chamber 22 and a friction force surface 44 adjoining the force increasing ramp 43. Thus, in the actuating position of the handle 4, the free end 42 of the leaf spring 39 rests on the force increasing ramp 43 of the force increasing surface 26, which is inclined in the direction of the wall 40 of the receiving chamber 22. When the handle 4 moves into the emergency actuation position, the handle 4 moves the free end 42 of the leaf spring 39 along the force increasing ramp 43 up to the friction force surface 4 running parallel to the wall 40 of the receiving chamber 22. This movement takes place against an increase in force in the form of a resistance force W, which corresponds to the sum of the restoring force generated by the restoring element 10 and the counterforce generated by the leaf spring 39.

In the Figures 29 to 31 a third embodiment of the resistance device 25 is shown, which is arranged on the first connection device 11. The resistance device 25 has the force increasing surface 26, which is formed on the handle 4 in this embodiment, and a torsion spring 45. The torsion spring 45 is formed with a first spring leg 46 and a second spring leg 47, the torsion spring 45 being mounted on the pivot axis 19. As the Figures 29 to 31 show, the torsion spring 45 is arranged within the connecting web 17, the connecting web 17 having a lateral through opening 48. The first spring leg 46 extends through the through opening 48 and protrudes from the connecting web 17, with the second spring leg 47 also protruding from the connecting web 17, but this is not absolutely necessary for the invention. In the in the Figures 29 to 31 In the handling position of the handle 4 shown, the connecting web 17 supports the first spring leg 46. More specifically, an edge supports the first spring leg 46 and the second spring leg 47 from the through opening 48 of the connecting web 17. Furthermore, in the handling position, the first spring leg 46 is arranged at a distance from the force increasing surface 26 designed as a wall section of the receiving space 18. When the handle 4 moves from the handling position in the direction of the actuation position, the handle 4 is pivoted about the pivot axis 19, so that the force increasing surface 26 formed on the handle 4 moves in the direction of the first spring leg 46. In the actuating position of the handle 4, the first spring leg 46 rests against the force increasing surface 26, which the operator perceives as a stop, with the door lock 5 opening electrically in the actuating position or already being opened during normal operation. In a de-energized emergency operation, the handle 4 must then - as already described above for the second embodiment - be moved with increased actuation effort in the direction of the emergency actuation position in order to open the door lock 5 mechanically, for which an increase in force is required. Because when the handle 4 moves into the emergency actuation position, the force increasing surface 26 pushes the first spring leg 46 in the direction of the second spring leg 47 against a resistance force which corresponds to the sum of the restoring force generated by the restoring element 10 and a counterforce generated by the torsion spring 45. The torsion spring 45 is thus compressed when the handle 4 moves from the operating position into the handling position.

Reference is made below to the Figures 32 to 36 taken, which relate to a fourth embodiment for the resistance device 25, which in turn is also arranged on the second connecting device 15. The resistance device 25 has a retaining lever 50 arranged on the handle holder 7 and a blocking projection 51 formed within the connecting projection 20. The retaining lever 50 has a retaining hook 52 at its free end. Furthermore, the retaining lever 50 is pivotally mounted on the handle holder 7 against a restoring force of a spring element 53. In the starting position, the blocking projection 51 extends into a movement path 54 of the retaining hook 52 of the retaining lever 50, such as from the Figure 34 is visible. In the Figure 34 the handle 4 is arranged in its rest position, with the retaining hook 52 and the blocking projection 51 being arranged at a distance from one another for this position. The retaining lever 50 extends over the blocking projection 51. In contrast, the representation of the Figure 35 the handle 4 is arranged in its operating position, so that the handle 4 is arranged pivoted and the retaining hook 52 is arranged to engage behind the blocking approach 51. In the case of an electrical opening, the user perceives an increase in the actuation force in this position, although the user will not increase the effort as a result of the electrical opening. This is different in the case of an emergency operation, as is the case Figure 36 shows in which the handle 4 is moved beyond its operating position and is arranged in its emergency operating position. When the handle 4 moves from the operating position into the emergency operating position, the retaining hook 52 moves over the blocking attachment 51, with the retaining lever 50 being pivoted against the retaining force of the spring element 53 in a direction pointing away from the blocking attachment 51, so that the retaining hook 52 can overcome the blocking approach 51. So that the retaining lever 50 comes out of the in Figure 36 position shown in Figure 34 can return to the starting position shown, the blocking projection 51 has an oblique restoring surface 55. The reset surface 55 is formed on a side of the blocking projection 51 facing the spring element 53. It can be seen that for this reset, the force of the restoring element 10 is greater than the retaining force of the spring element 53. In summary, the invention provides a door handle arrangement 3 of a motor vehicle 2, the door handle arrangement 3 having an electro-mechanical locking system 14 with a door lock 5, a handle holder 7, an in a handle 4 which can be moved in a rest position and a handling position and a restoring element 10 which biases the handle 4 in the direction of the handle holder 7. When installed in a vehicle door 2, the handle 4 is arranged to run flush with the outside 6 of the vehicle door 2 in the rest position and is arranged to be exposed in an opening direction 9 in the handling position for actuation relative to the outside 6 of the vehicle door 2. For actuation, the handle 4 is designed to be relatively movable from its handling position into an actuation position for an electrical opening of the door lock 5 or into an emergency actuation position that goes beyond the actuation position for a mechanical opening of the door lock 5 to the handle holder 7. The handle 4 is motion-coupled to the handle holder 7 via a first connecting device 11 and via a second connecting device 15, the first connecting device 11 and the second connecting device 15 being arranged at a distance from one another. A resistance device 25 is arranged within the first connecting device 11 and/or the second connecting device 15, which generates a resistance force that counteracts the actuation when the handle 4 is actuated from the actuating position into the emergency actuating position. According to the invention, the resistance force represents either a force threshold to be overcome by the operator, which must be briefly overcome by the operator only to move the handle 4 from the operating position in the direction of the emergency operating position, or an increase in force to be applied by the operator, which is provided by the The operator must continually move the handle 4 from the operating position until the emergency operating position is reached.
