Description

The invention is directed to a motor vehicle handle arrangement, comprising a bearing bracket which can be fastened to an inside of a door or flap of a motor vehicle, a handle element which is attached to a first swivel arm and a second swivel arm, and a lock cylinder which can be mounted on the motor vehicle handle arrangement, wherein the first pivot arm and the second pivot arm are non-rotatably connected to at least one bearing axis, which is rotatably mounted on the bearing bracket and which extends parallel to a longitudinal direction of the handle element, so that the handle element between a basic position in which the handle element is flush with an outer contour of the Door or flap is arranged to run, and is movable to an open position. The invention is also directed to a method for assembling such a motor vehicle handle arrangement.

A motor vehicle handle arrangement of the type mentioned is, for example, from WO 2017/153088 A1 famous. Furthermore, motor vehicle handle assemblies are known and available in various designs. Motor vehicle handle assemblies with movable handle elements as well as motor vehicle handle assemblies with so-called fixed handle elements are known. While in the case of movable handle elements, a section of the handle element to be reached under or behind by the user is pivoted or moved in a translatory manner by the action of force, the handle element in the case of stationary door handles cannot be pivoted or moved in a translatory manner. In the case of a motor vehicle handle arrangement with a stationary handle element, the handle element is opposite the door or flap of the motor vehicle largely immobile. In the absence of a mechanical adjustment path, motor vehicle handle arrangements with stationary handle elements do not form a continuous mechanical chain of action from the handle element to a door lock. Instead, the door lock is electrically controlled as a function of a detected actuation, so that the mechanical hardware can be reduced and costs and weight can be saved in the motor vehicle handle arrangement.

Furthermore, electrical motor vehicle handle arrangements are known from the prior art, in which a lock cylinder is arranged in a concealed manner behind the handle element. In an emergency, in these motor vehicle handle arrangements, the handle element can be lifted off the lock cylinder so that a key can be inserted past the handle element into the lock cylinder in order to mechanically unlock the door lock. However, it is disadvantageous here that the lock cylinder is arranged at an angle to the longitudinal axis of the handle element, which makes it difficult to insert the key. Furthermore, in the known motor vehicle handle arrangements, the lock cylinder must always be preassembled on the bearing bracket before the bearing bracket is attached to the inside of the door of the motor vehicle. This mounting arrangement proves to be disadvantageous with regard to the aspect of theft protection, since it is relatively easy for a thief to "knock" the lock cylinder through the bearing bracket in the direction of the vehicle interior with appropriate force and thus open the door of the motor vehicle by force.

From the DE 10 2013 102106 A1 a trough housing is known which can be mounted from the outside and fastened to a bearing bracket installed on the inside of the door.

The invention is therefore based on the object of developing a motor vehicle handle arrangement in a structurally simple manner and inexpensively, which is inexpensive in its Production is, enables quick and convenient assembly, increases theft protection and enables convenient handling, should it be necessary to operate the lock cylinder with a key.

This object is achieved according to the invention by a motor vehicle handle arrangement having the features according to patent claim 1.

The motor vehicle handle arrangement according to the invention has a bearing bracket that can be fastened to an inside of a door or flap of a motor vehicle, a recess housing that can be inserted from an outside of the door or flap into a recess formed in the door or flap and has a receiving space, a handle element which is attached to a first swivel arm and a second swivel arm is attached, and a lock cylinder which extends at least in sections within the receiving space and can be mounted on the motor vehicle handle arrangement from the outside of the door or flap, the first swivel arm and the second swivel arm being non-rotatably connected to at least one bearing axis, which is rotatably mounted on the bearing bracket and which extends parallel to a longitudinal direction of the handle element, so that the handle element between a basic position in which the handle element is flush with an outer contour of the door or flap ufend is arranged, and is movable in a deployment position in which the handle element protrudes from the receiving space of the trough housing with respect to the outer contour of the door or flap, wherein the lock cylinder extends perpendicular to the longitudinal direction of the handle element and the handle element covers the lock cylinder in the basic position and in the deployed position releases the lock cylinder for insertion of a key, a retaining latching device exerting a predetermined retaining force on the handle element in the direction of the basic position, and the handle element in a Actuation of the handle element with a deployment operating force directed away from the bearing bracket, which is greater than the predetermined retaining force, can be moved into the deployment position in which the handle element is arranged to release the lock cylinder for insertion of a key.

The object on which the invention is based is also achieved by a method for assembling a motor vehicle handle arrangement having the features according to patent claim 11.

The inventive method is used to assemble a motor vehicle handle arrangement according to claim 1, wherein the bearing bracket is fastened on the inside of the door or flap of the motor vehicle, then the first pivot arm and the second pivot arm of the handle element through the recess formed on the outside in the door or flap with the internally fastened bearing bracket are connected, and after connecting the handle element to the bearing bracket, the handle element is actuated with a deployment actuating force directed away from the bearing bracket, which is greater than the predetermined retaining force, the grip element being moved into the deployment position as a result of the actuation and thereby the handle element is arranged releasing the lock cylinder for insertion of a key, the handle element being held in the open position by the retaining latching device and thus arranged in a pre-assembly position in which the lock cylinder is externally seen after the door or flap is mounted on the motor vehicle handle assembly.

Advantageous and expedient configurations and developments of the invention emerge from the respective subclaims.

The motor vehicle handle arrangement according to the invention has a handle element and a lock cylinder, which are set up and arranged in such a way that they are coordinated with one another that the lock cylinder is protectively covered and covered by the handle element when there is no access to the lock cylinder is required. Should the door lock nevertheless have to be unlocked with the help of a key, which can happen, for example, in the event of a system failure of the on-board network or a de-energized state of the motor vehicle, the handle element can be lifted from the lock cylinder by an exhibition actuation force to be applied by a user to such an extent that a key can be inserted is convenient and comfortable for the user, because according to the invention the lock cylinder is arranged perpendicular to the longitudinal direction of the handle element and the bearing axis, ie the lock cylinder extends in its longitudinal direction at an angle of about 90 ° to the longitudinal direction of the handle element and the bearing axis. The fact that the lock cylinder is mounted from the outside of the vehicle door and is thus supported either on the door panel, the recess housing or the bearing bracket, increases theft protection, because it is far more difficult for a thief to break into a motor vehicle because the lock cylinder is off its mounting position, because this is the only way for the thief to manipulate the lock cylinder with this mounting arrangement.

In an advantageous embodiment of the motor vehicle handle arrangement, the invention provides that sensor electronics are provided for detecting an actuation of the grip element caused by a user, and the sensor electronics, upon detection of actuation of the grip element by a user, with a normal actuation force directed away from the bearing bracket, which is smaller than the predetermined retention force, opens the door or flap electrically and the handle element remains arranged in its basic position. The sensor electronics consequently opens the door or flap electrically upon detection of an actuation of the handle element by a user with a normal actuation force directed away from the bearing bracket, which is less than the predetermined restoring force. In that the normal operating force is smaller than the predetermined retaining force, the grip element remains arranged in its basic position. The grip element is therefore not moved during normal actuation by a user because the usual normal actuation force is less than the retention force of the retention latching device. The grip element gives the user the appearance of a stationary or quasi-stationary grip element, which is desired by the present invention. In combination with such a fixed handle element, an electrically controlled door lock is used. Such electrically controlled door locks are generally known under the designation "E-Latch". The way in which the actuation of the grip element is detected can be solved in different ways. For the purposes of the invention, switches or capacitive sensors can be used on or in the handle element. The use of inductive sensors is also possible in the context of the invention. For the purposes of the invention, the term "sensor electronics" used is to be understood as meaning both a switch, a button, a capacitive sensor or an inductive sensor which is used to detect an actuation of the handle element caused by a user.

To increase the stability of the mounting of the handle element designed in the manner of a folding handle on the bearing bracket, the invention provides in a further embodiment that the handle element is attached to a third pivot arm which is connected to the at least one bearing axis in a rotationally fixed manner. The third swivel arm can be arranged between the first and second swivel arm or to the side of the first or second swivel arm.

In an embodiment of the invention, it is structurally particularly favorable if the retaining latching device has an elastic spring element and a sliding element, the sliding element being coupled in terms of movement to the grip element and a first spring leg of the elastic spring element being attached to it the sliding element is supported. In the context of the invention, the expression "motion-coupled" is to be understood as meaning that the sliding element moves with the grip element when the grip element is actuated by a user and moved out of the basic position. Due to the design as an elastic spring element, the restoring force can be adjusted very precisely, which has a positive effect on the opening force to be applied in an emergency. In addition, the use of an elastic spring element is economically favorable.

In a further embodiment, the invention provides that a second spring leg of the elastic spring element is supported on a support extension which is formed on the bearing bracket or on the trough housing. During operation of the motor vehicle handle arrangement, it is essential that the second spring leg is supported on a support extension that is stationary with regard to the handle element, so that the elastic spring element can be compressed in accordance with its prescribed mode of action in order to apply its predetermined force in accordance with the operating state of the motor vehicle handle arrangement unfold.

With regard to a structurally simple movement coupling of the grip element and the sliding element, the invention provides in a further embodiment that the sliding element is arranged on the first pivot arm or on the second pivot arm so that it can move with it. The sliding element can of course also be arranged on a third swivel arm, provided a third swivel arm is provided. The sliding element can either be attached to a swivel arm or it can be arranged to the side of one of the swivel arms, in which case the sliding element is also attached to the at least one bearing axis and is coupled for movement to one of the swivel arms via a web, for example.

Normally, the elastic spring element would be compressed during a movement of the grip element, so that the force generated by the elastic spring element upon compression would increase linearly. For the purposes of the invention, however, it is desirable that the elastic spring element generates an increasing counterforce at the beginning of the movement of the handle element from the basic position in the direction of the deployment position, this counterforce to decrease abruptly before reaching the deployment position so that the user can comfortably use the handle element can move into the open position without excessive effort. Only an initially increased counterforce is desired so that there is no unintentional but conscious movement of the grip element. For this purpose, the invention provides in an embodiment that a movement contour is formed on the sliding element, on which the first spring leg of the elastic spring element is supported. The compression of the elastic spring element and thus the counterforce generated by the elastic spring element is determined in accordance with the movement contour.

The invention provides in a further embodiment that the movement contour is subdivided into a retaining section and a latching section adjoining the retaining section, the first spring leg of the elastic spring element being angled and arranged in the open position on the latching section in such a way that the grip element is arranged held locked in its deployed position. If there is an emergency, either as a result of a system failure or a power failure, the motor vehicle handle arrangement according to the invention consequently offers the possibility of unlocking the door lock with the aid of a mechanical key in a very convenient way for an emergency opening. This is made possible because the grip element, when actuated with a deployment actuating force directed away from the bearing bracket, is greater than that predetermined restoring force is movable into an open position in which the handle element no longer covers the lock cylinder, but rather releases it so that a key can be inserted into the lock cylinder without the user having to hold the handle element in the open position. It goes without saying that the opening actuating force must be significantly greater than the normal actuating force, so that a user really only acts on the grip element with a correspondingly large force in an emergency. The motor vehicle handle arrangement according to the invention can therefore be assigned neither to the group of motor vehicle handle arrangements with a movable handle nor to the group of motor vehicle handle arrangements with a fixed handle. Rather, the motor vehicle handle arrangement according to the invention uses aspects of both groups and is consequently characterized by a pseudo-fixed handle which remains fixed in its basic position during normal operation and which can only be moved into an open position in an emergency with a correspondingly large opening actuation force, to allow an unhindered To release access to the lock cylinder.

In order for the elastic spring element to generate a non-linear or a continuously increasing counterforce when the handle element is moved, the invention provides in a further embodiment that the first spring leg of the elastic spring element moves when the handle element moves from the basic position in the direction of the deployment position along the Retaining portion moves, wherein the retaining force generated by the elastic spring element increases during the movement of the first spring leg of the elastic spring element along the retaining portion, and wherein the retaining force generated by the elastic spring element when the first spring leg is arranged on the latching portion is smaller than the retaining force generated by the elastic spring element when the grip element is arranged in the basic position.

Finally, in an embodiment of the motor vehicle handle arrangement, the invention provides that the sliding element consists of a plastic, in particular polyoxymethylene, or of sheet metal. With this configuration, a sufficiently desired service life of the sliding element can be achieved.

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

Further details, features and advantages of the subject matter of the invention emerge from the following description in connection with the drawing, in which an exemplary and preferred embodiment of the invention is shown.

In Figure 1 a vehicle or motor vehicle 1 in the form of a car is shown as an example, which in the example has four doors 2a (two of which are from Figure 1 can be seen), which can be opened via a motor vehicle handle arrangement 3 and in particular with the aid of a handle element 4. The motor vehicle handle arrangement 3 according to the invention can of course also be used for a flap 2b, such as one in FIG Figure 1 shown tailgate or an engine compartment flap or a trunk lid can be used. With reference to the Figures 1 and 2 the doors 2a are locked via respective door locks 5 and can be opened from the outside via a respective actuation of the handle element 4. The handle element 4 has a handle part that can be gripped from behind and which can be actuated to open the door lock 5, the actuation in the exemplary embodiment shown in the figures being a pulling force exerted by a user on the handle element 4, which is determined by sensor electronics built into the handle element 4 6 is detected. To open the door 2a (or flap 2b), an electromechanical locking system 7 is then activated in normal operation, with the aid of which the door lock 5 can be opened or closed. The sensor electronics 6 detects a force exerted on the handle element 4 and, when such a force is detected, opens the door lock 5, with the handle element 4 remaining undeflected on the door 2a during this actuation and giving the user the impression that it is stationary Act grip element 4, which remains stationary in its position or basic position despite the application of a pulling force. for the sensor electronics 6, the most varied of solutions are known from the prior art, which can also be used in the motor vehicle handle arrangement 3 according to the invention. For example, a switch or button and a capacitive or inductive sensor can be used on or in the handle element 4. Since these are known measures, a detailed description of the sensor electronics 6 is dispensed with.

In Figure 3 a perspective view of the door 2a of the motor vehicle 1 is shown. Can be seen in the Figure 3 a recess 8 formed in the door 2a. A recess housing 9 can be inserted into the recess 8 from the outside, ie from the outside of the door 2a, ie the recess housing 9 is inserted from the outside into the recess 8 formed in the door 2a during assembly. The trough housing 9 forms a receiving space 10 in which, among other things, the grip element 4 is arranged at least in sections. Furthermore, the Figure 3 it can be seen that on the inside of the door 2a, ie on the inside of the door, a bearing bracket 11 is attached, which serves to mount the handle element 4 and a lock cylinder 12 of the motor vehicle handle arrangement 3, among other things.

the Figure 4 shows a front view of the motor vehicle handle arrangement 3, the recess housing 9, the handle element 4 and a lock cylinder 12 concealed by the handle element 4 being shown. The handle element 4 is movably mounted on the bearing bracket 11 via a first swivel arm 14 and a second swivel arm 15, the two swivel arms 14, 15 and the lock cylinder 12 being covered behind the handle element 4 in Figure 4 are arranged. Optionally, a third swivel arm 16 can also be provided, which would further increase the mounting of the grip element 4. In Figure 4 the third pivot arm 16 is arranged between the first pivot arm 14 and the second pivot arm 15. The first pivot arm 14 and the second pivot arm 15 (and optionally also the third pivot arm 16) are each end connected to the grip element 4, whereas the respective other ends of the pivot arms 14, 15 (and possibly 16) are connected non-rotatably to a bearing axis 17, which is clearer from the Figures 6 and 7 (In the sectional view, only the first pivot arm 14 is in the Figures 6 and 7 shown), which each show a side sectional view of the motor vehicle handle arrangement 3 according to the invention for different positions of the handle element 4. The lock cylinder 12 is arranged to the side of the second swivel arm 15 or on the side of the second swivel arm 15 facing away from the first swivel arm 14, the lock cylinder 12 being attached to the motor vehicle handle arrangement 3 on the outside, ie from the outside of the door 2a. The lock cylinder 12, which is mounted on the outside or from the outside of the door 2a, can either be mounted on the bearing bracket 11 or the trough housing 9, the lock cylinder 12 also being able to be supported on a body panel of the door 2a. Like that Figures 6 and 7 It can also be seen that the lock cylinder 12 extends in sections within the receiving space 10 of the trough housing 9, the pivot arms 14, 15 being designed essentially in the shape of a horseshoe. The bearing axis 17, with which the first swivel arm 14 and the second swivel arm 15 (and optionally the third swivel arm 16) are each connected in a rotationally fixed manner, is rotatably mounted on the bearing bracket 11, the bearing bracket 11 in the Figures 6 and 7 is only shown schematically. The bearing axis 17 can be a continuous, single axis with which the pivot arms 14, 15 are connected in a rotationally fixed manner. Alternatively, respective bearing axles could also be provided for each swivel arm 14, 15 (possibly 16), which are mounted on respective pivot bearings. Regardless of this, the situation in the present invention is such that the bearing axis 17 is parallel to a longitudinal direction 18 (see, for example Figure 4 ) of the handle element 4, so that it is present at the handle element 4 is a folding handle that can be grasped from behind by a user for actuation in order to move the handle element 4 from a basic position, which is shown in FIG Figure 6 is shown in a deployed position, which is shown in Figure 7 is shown to move. A movement into the open position is only intended for emergency operation. As already mentioned above, the present case is a pseudo-fixed or quasi-fixed grip element 4, in which the sensor electronics 6 detects an actuation of the grip element 4 caused by a user. For normal operation, it is sufficient if the user pulls on the handle element 4 with a normal operating force 19 directed away from the bearing bracket 11, the normal operating force 19 (see FIG Figure 6 ) is smaller than a predetermined retaining force 20 which is exerted by a retaining latching device 21 on the grip element 4 in the direction of the basic position. This is because the normal actuation force 19 is sufficient and is detected by the sensor electronics 6, so that the door 2a (or flap 2b) is opened electrically and the handle element 4 remains arranged in its basic position. In the basic position (see Figure 6 ) the handle element 4 is arranged flush with an outer contour 22 of the door 2a, whereas in the open position (see Figure 7 ) the handle element 4 protrudes from the receiving space 10 of the trough housing 9 with respect to the outer contour 22 of the door 2a. As can be seen from the synopsis of the Figures 2, 4 and 6th results, the lock cylinder 12 extends perpendicular to the longitudinal direction 18 of the handle element 4, ie the lock cylinder 12 extends at an angle of almost 90 ° to the bearing axis 17, the handle element 4 in its basic position (see Figure 6 ) covers the lock cylinder 12. In the open position (see Figure 7 ) the handle element 4 unfolded from the recess housing 9 releases the lock cylinder 12 for insertion of a key 23. To the grip element 4 from the basic position To move into the deployed position, the user has to apply a deployment actuating force 24, directed away from the bearing bracket 11, which is greater than the predetermined retaining force 20.

The retaining latching device 21 has an elastic spring element 25 and a sliding element 26, as shown in FIG Figures 6 and 7 is shown. According to the invention, the sliding element 26 is coupled in terms of movement to the grip element 4. In the context of the invention, this is understood to mean that when the grip element 4 is moved, the sliding element 26 is also moved at the same time. The sliding element 26 can be arranged and fastened on the first pivot arm 14 or on the second pivot arm 15 (or on the third pivot arm 16). However, it is also conceivable that the sliding element 26 is separated and attached to the bearing axis 17 at a distance from the pivot arms 14, 15 and, for example, is connected to one or all of the pivot arms 14, 15 via a web, so that when the handle element moves 4 simultaneously pivots the sliding element 26 about the bearing axis 17. In other words, the sliding element 26 is arranged on the first pivot arm 14 or on the second pivot arm 15 such that it can be moved along with the latter. In the exemplary embodiment shown, the sliding element 26 consists of a plastic, in particular polyoxymethylene (POM), it also being conceivable that the sliding element 26 consists of a metal sheet. In the exemplary embodiment shown, the elastic spring element 25 is mounted on the bearing bracket 11, it also being conceivable that the elastic spring element 25 is fixed, for example, on the trough housing 9. A first spring leg 27 of the elastic spring element 25 is supported on the sliding element 26, whereas a second spring leg 28 of the elastic spring element 25 is supported on a support extension 29, which is formed on the bearing bracket 11 in the embodiment shown. Alternatively, the support extension 29 can also be formed on the trough housing 9.

The functioning of the motor vehicle handle arrangement 3 according to the invention is illustrated by Figure 5 illustrates, which shows a diagram in which the required actuation force F for moving the grip element 4 over the path S is shown. The dashed line shows a course in which the first spring leg 27 would only be supported on an attachment which is arranged on one of the pivot arms 14, 15. The solid line in Figure 5 stands for the force curve according to the invention, which is achieved with the help of a movement contour 30 formed on the sliding element 26, on which the first spring leg 27 of the elastic spring element 25 is supported, the first spring leg 27 when the grip element 4 moves in the direction of the deployment position Movement contour 30 slides along. The movement contour 30 is divided into a retaining section 31 and a latching section 32 adjoining the retaining section 31, such as the Figures 6 and 7 can be found. The retaining section 31 runs on a constant radius in relation to the bearing axis 17, whereas the latching section 32 extends on a smaller radius in relation to the bearing axis 17 compared to the radius of the retaining section 31 If the normal actuating force 19 is actuated, the grip element 4 remains in its basic position, since the normal actuating force 19 is smaller than the retaining force 20 of the elastic spring element 25. Only when the user applies a movement force 33 that exceeds the retention force 20 does the grip element 4 move out of the basic position A (see FIG Figure 5 and 6th ) in the direction of opening position B (see Figure 5 and 7th ) emotional. The elastic spring element 25 is compressed when the handle element 4 is moved from the basic position A in the direction of the deployment position B and consequently generates a increasing retention force 34. This increasing retention force 34 prevents an unintentional opening actuation by a user and is generated by the elastic spring element 25 in that the first spring leg 27 of the elastic spring element 25 moves when the handle element 4 moves from the basic position in the direction of the opening position along the Retaining portion 31 moved. Consequently, the retaining force 20 generated by the elastic spring element 25 increases when the first spring leg 27 of the elastic spring element 25 moves along the retaining section 31 Retaining section 31 to rise to 130 Newtons. At the end of the retaining section 31, the movement contour 30 of the sliding element 26 has an abrupt change in radius on the latching section 32, the radius of the latching section 32 being smaller than the radius of the retaining section 31. This abrupt change in radius is also shown in the course of the line in the diagram in Figure 5 , because the elastic spring element 25 can "relax" and thereby exerts a deployment actuating force 24 when the handle element 4 moves into the deployment position, which is smaller than the retention force 20 in the basic position of the handle element 4 Figure 6 As can be seen, the first spring leg 27 of the elastic spring element 25 is angled and, in the deployed position, is arranged latched onto the latching section 32 in such a way that the grip element 4 is held locked in its deployed position. When the first spring leg 27 is arranged on the latching section 32 in the deployment position B of the handle element 4, the retention force 20 generated by the elastic spring element 25 is smaller than the retention force 20 generated by the elastic spring element 25 when the handle element 4 is arranged in the basic position A.

In the method according to the invention for assembling the motor vehicle handle arrangement 3 described above, in a first step the bearing bracket 11 is fastened on the inside of the door 2a of the motor vehicle 1, and then in a second step of assembly the first pivot arm 14 and the second pivot arm 15 of the handle element 4 are connected to the bearing bracket 11 fastened on the inside through the cutout 8 formed on the outside in the door 2a. After the grip element 4 has been connected to the bearing bracket 11, the grip element 4 is actuated with a deployment actuating force 24 directed away from the bearing bracket 11, which is greater than the predetermined retaining force 20, the grip element 4 being moved into the deployment position as a result of the actuation and thereby the grip element 4 is arranged to release the receiving space 10 for mounting the lock cylinder 12. The handle element 4 is held in the deployed position by the retaining latching device 21 and is thus arranged in a pre-assembly position in which the lock cylinder 12 is mounted on the motor vehicle handle arrangement 3 from the outside of the door 2a.
