Definitions

  • 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.
  • 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 .
  • the handle 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.
  • a door handle arrangement 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.
  • the door handle arrangement of a motor vehicle 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.
  • the handle 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.
  • 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.
  • the invention provides a door handle arrangement which is characterized by a simple construction.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the elasticity element is a foam part that pushes the force-increasing surface in the direction of its base position.
  • the elasticity element 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the retaining hook and the blocking approach are arranged at a distance from one another, and the retaining lever extends over the blocking approach.
  • the retaining hook and the blocking approach come closer together.
  • 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.
  • the retaining hook is arranged behind the blocking approach.
  • 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.
  • the blocking approach has an oblique restoring surface, which is on a side of the blocking approach facing the spring element is trained.
  • 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.
  • 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.
  • the handle 4 By moving the handle 4 accordingly, the associated vehicle door 2 can then be opened.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 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.
  • 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.

  • 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.

  • 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.
  • 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 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.

  • 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.

  • 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 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.

  • the operator 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).

  • the lever mechanism 21 has the main lever 23, which connects the handle holder 7 to the handle 4.
  • 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.
  • 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.
  • 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.
  • 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.
  • the handle 4 is pivoted through an angle about the pivot axis 19, which is between 3° and 4°.
  • 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.
  • 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.
  • the door lock 5 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.
  • 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.
  • the elasticity element 28 can, for example, be a foam part that pushes the force increasing surface 26 towards its base position.
  • 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.
  • 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.
  • 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.
  • 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 ⁇ of the handle 4 about the pivot axis 19.
  • 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).
