Abstract
A door handle assembly for a motor vehicle includes an operating handle moveably supported on a handle mounting, a mechanical coupling device and a locking device. An acceleration force can move the locking device from a normal operating position, in which an actuation of the operating handle is possible, in a first blocking direction, in which an actuation of the closing assembly via the operating handle and/or the coupling device, is blocked. The locking device also blocks the door handle assembly when long lasting or strongly pronounced oscillations occur as a result of a crash. In that event, the locking device can move from the normal operating position in a second blocking direction, in which an actuation of the closing assembly via the operating handle and/or the coupling device is blocked, wherein the second blocking direction is oriented opposite the first blocking direction.

DETAILED DESCRIPTION
(20) In FIG. 1, a vehicle, or motor vehicle 1, respectively, in the form of a passenger car, is shown by way of example, having four doors 2, which can be opened by means of a door handle assembly 3, and in particular, using a door handle, or operating handle 4, respectively. The doors 2 are firmly closed by means of respective closing assemblies 5, and can only be opened from the outside by means of a respective movement of the operating handle 4. This movement of the operating handle 4 can consist of a pulling and/or lifting movement, wherein the corresponding movement of the operating handle 4 is mechanically transferred to the corresponding closing assembly 5 via at least one coupling device. The corresponding closing assembly 5, and thus the door 2 allocated thereto, can then be opened by means of the movement of the operating handle 4.
(21) In FIG. 2, the door handle assembly 3 according to a first embodiment is depicted in greater detail in a perspective view. The door handle assembly 3 has a frame-like handle mounting 6, wherein, for reasons of clarity in the FIGS. 2 and 6-9, which relate to a first embodiment of the door handle assembly 3, a depiction of the operating handle 4 is omitted. The handle mounting 6 serves, in the known manner, for the attachment of the operating handle 4, and is fastened to the door panel on the inside of the door by means of threaded fasteners that are not depicted, wherein the operating handle 4 is disposed on the outside of the door. For this, the handle mounting 6, for the purpose of saving on materials, is substantially formed by a frame structure, having various receiving spaces and mounting spaces, in order to be able to also receive, in addition to the operating handle 4, which is moveably and/or pivotally supported on the handle mounting 6 in order to open a corresponding door 2 of the motor vehicle 1 by a user, a mechanical coupling device 7, and a locking device 8, as well as, optionally, a locking cylinder that is not shown in detail in the figures.
(22) A movement of the operating handle 4 can be transferred to the corresponding vehicle-side closing assembly 5 via the mechanical coupling device 7, in order to open the door 2. The locking device 8, serving as a mass locking device, can change in its position from a normal operating position to a blocking position through the effects of a force, such as an acceleration force, for example, wherein an actuation of the operating handle 4 is possible in the normal operating position, whereas, in the blocking position of the locking device 8, moveably retained on the handle mounting 6, an actuation of the closing assembly 5 by the operating handle 4 and/or a movement of the coupling device 7 by means of an actuation of the operating handle 4, is blocked. The locking device 8 can end up thereby in the blocking position by means of a movement in either a first blocking direction or in a second blocking direction. The second blocking direction is opposite the first blocking direction, as shall be explained below in detail.
(23) As can be seen in FIG. 2 and FIG. 4, which show the coupling device 7 in a perspective view, the coupling device 7 comprises a mass 9, a projecting pivot arm 10, and axle journals 11, by means of which the coupling device 7 is rotatably supported on the handle mounting 6. The handle mounting 6 has receiving fixtures 12 for the rotatable support of the axle journals 11. The mass 9 serves as a counterbalancing mass, to counteract against the weight of the operating handle 4 during an accident, or to counteract against the effects of an acceleration force. It should thus substantially compensate for the forces generated by the operating handle 4 and the coupling device 7, wherein the mass 9 is optional, and must not necessarily be provided. A movement of the operating handle 4 is transferred to the coupling device 7 by means of the pivot arm 10. The coupling device 7 is pivotally, or rotatably supported in a receiving space of the handle mounting 6 by means of the axle journals 11. The movement to the coupling device 7 introduced by the operating handle 4 is transferred therefrom to a transferring element, not shown, for the closing assembly 5 via a collar 13. In the present case, the collar 16 formed on the coupling device 7 is designed to accommodate a Bowden cable, which is retained in a form-locking manner at one end in a hole in the coupling device 7 provided for this purpose. For a reliable guidance of the Bowden cable, a guide groove is formed on the coupling device 7.
(24) As can be derived from the FIGS. 3 and 4, by way of example, the mechanical coupling device 7 also has a movement projection 14, designed in the manner of a lever, which acts together with the locking device 8. A movement cavity 15 is formed on the locking device 8 itself, into which the movement projection 14 of the coupling device 7 can be inserted for an actuation of the operating handle 4 when the locking device 8 is disposed in the normal operating position.
(25) In the first embodiment of the door handle assembly 3, the locking device 8 is designed in sections as a hollow cylinder 16, as is shown in FIGS. 2 and 6-9. The movement cavity 15 is formed in the shell of the hollow cylinder 16, running in the longitudinal direction, and represents a type of incision in the open front end 17 of the hollow cylinder 16 (see FIG. 3). In other words, the movement cavity 15 of the locking device 8, starting at the open front end 17 of the hollow cylinder 16, is formed running in the longitudinal direction thereof.
(26) A state of the door handle assembly 3 is shown in FIG. 2, in which the locking device 8 is in its normal operating position and is thus not activated. Furthermore, in this state, the coupling device 7 is disposed in the rest position, because the operating handle is not actuated. In the normal operating position of the locking device 8, when the operating handle 4 is not actuated, the movement projection 14 extends into the open front end 17 of the hollow cylinder 16. In this state of the coupling device 7 and the locking device 8, the movement cavity 15 is disposed in the movement path of the movement projection 14, such that when the operating handle 4 is actuated, the movement projection 14 pivots the coupling device 7 coupled to the operating handle 4 about the Z axis of the door handle assembly 3, and is moved toward the movement cavity 15. This procedure is shown in FIG. 6, in which the operating handle 4 is actuated such that the movement projection 14 moves toward the movement cavity 15, and is disposed in part therein. With a further actuation of the operating handle 4 and the accompanying pivoting of the coupling device 7, the movement projection 14 moves through the movement cavity 15, and out of the hollow cylinder 16, and away from the locking device 8, as is shown in the depiction in FIG. 7. The operating handle 4 is completely actuated in this state, such that the coupling device 7 is also pivoted on the handle mounting 6 to the maximum extent, by means of which the movement projection 14 is moved such that it is moved through the movement cavity 15, and is now disposed outside of the hollow cylinder 16 of the locking device 8. After actuating the operating handle 4, i.e. when a user releases the operating handle 4, then this is pivoted back due to the tension of the spring in the coupling device 7, by means of which the movement projection 14 again extends into the open front end 17 of the hollow cylinder 16, or, respectively, is disposed in the interior of the hollow cylinder 16.
(27) FIGS. 8 and 9 show states of the door handle assembly 3 according to the first embodiment, in which there is an accelerating force to the door handle assembly 3 in the direction of the Y axis, and in particular, acting on the locking device 8. The locking device 8 is supported on the handle mounting 6 by means of a pivot axle 18, such that it can rotate about the X axis of the door handle assembly 3, and has a mass weight 19. The locking device 8 is supported thereby at its center by the pivot axle 18, such that it can rotate, wherein the mass weight 19 is disposed on the locking device 8, offset to the pivot axle 18. As a result of this configuration of the mass weight 19, the locking device 8 is moved out of its normal operating position as a result of the effects of an acceleration force in the direction of the Y axis (for example, as a result of a vehicle accident). The movement of the locking device 8 in the first or second blocking direction is a rotational movement about the pivot axle 18 as a result of the structural construction and the support of the locking device 8.
(28) FIGS. 8 and 9 show exemplary states, in which the locking device 8 is first moved from the normal operating position in a first or second blocking direction, and is then in a respective blocking position, wherein the locking device 8 can move in both blocking directions during a vehicle accident as a result of oscillations. Then, the locking device 8 is first deflected in a first blocking direction as a result of the acceleration force acting thereon, and then rebounds, which is expressed by a movement of the locking device in the second blocking direction, which can also be referred to as a swinging movement in the first and second blocking directions. The locking device 8 passes through the normal operating position thereby, without remaining in this position. In FIG. 8, the locking device 8 is rotated 90 about the pivot axis 18 (Y axis) as a result of the effects of an acceleration force in the first blocking direction 21 (see arrow 21 in FIG. 8), such that the movement cavity 15 is then no longer in the movement path of the movement projection 14. In FIG. 9, in contrast, the locking device 8 is rotated +90 about the pivot axle 18 (Y axis) as a result of the effects of an acceleration force, or as a result of the swinging movement of the locking device 8 described above, in the second blocking direction 22 (see arrow 22 in FIG. 9), by means of which the movement cavity 15 now is no longer in the movement path of the movement projection 14. An actuation of the operating handle 4 or a pivoting of the coupling device 7, which is rotatably supported, about the point of rotation 20 for its axle journals 11, on the handle mounting 6, is blocked in FIGS. 8 and 9 as a result of the rotation of the locking device 8 about the pivot axle 18, because the movement projection 14 cannot move out of the interior of the hollow cylinder 16, but instead, hits the inner walls of the hollow cylinder 16 when deflected. The movement projection 14 is thus caught in the hollow cylinder 16 when the locking device 8 moves in the first or second blocking direction 21, 22, for which reason this can also be referred to as a catch cylinder, or locking socket 16. In the first embodiment of the door handle assembly 3, which FIGS. 1-9 are based on, the pivot axle 18 of the locking device 8 is oriented substantially transverse to the point of rotation 20 for the coupling device 7, in order to obtain the desired blocking of the operating handle 4, or the coupling device 7, when acted on by an acceleration force. Alternatively to the rotational angle of 90, about which the locking device 8 in FIGS. 8 and 9 is rotated, and can swing, from the normal operating position, as a result of the effects of an acceleration force, in the first or second blocking direction 21, 22, a smaller rotational angle or a larger rotational angle, of 285, for example, about the pivot axle 18, is also conceivable.
(29) FIGS. 8-18 relate to a second embodiment of a door handle assembly 3 according to the invention. The second embodiment of the door handle assembly 3 also comprises a frame-like handle mounting 6 for attaching the operating handle 4, wherein, here too, for reasons of clarity, a depiction of the operating handle 4 is omitted. The handle mounting 6 of the second embodiment likewise supports, aside from the operating handle 4, a mechanical coupling device 7, by means of which a movement of the operating handle 4 can be transferred to the corresponding vehicle-side closing assembly 5 for opening the door 2, and a locking device 8, serving as a mass locking device, which can change its position, with the effects of an acceleration force, from the normal operating position, in which an actuation of the operating handle 4 is possible, to a blocking position, in which an actuation of the closing assembly 5 by means of the operating handle 4, and/or a movement of the coupling device 7 by means of an actuation of the operating handle 4, is blocked. The locking device 8 ends up in the blocking position here as well, by means of a movement in a first or second blocking direction.
(30) The coupling device 7 depicted in FIG. 13 has, as with the first embodiment form, a mass 9, a projecting pivot arm 10, and axle journals 11, for the rotatable support on the handle mounting 6, wherein corresponding receiving elements 12 are provided on the handle mounting 6 for the axle journals 11 (see FIG. 10, by way of example). With regard to the function of the mass 9, reference is made to the explanations referring to the first embodiment. As can further be derived from FIG. 13, the coupling device 7 has a movement projection 14 acting together with the locking device 8, wherein a movement cavity 15 is formed for this purpose on the locking device 8 (see FIG. 12), into which the movement projection 14 of the coupling device 7 can be moved for actuating the operating handle 4 when the locking device 8 is disposed in the normal operating position, as shall be explained in greater detail below.
(31) With the second embodiment of the door handle assembly 3, the locking device 8 is designed in sections as a disk element 23, as is shown, for example, in FIGS. 11 and 12. The movement cavity 15 is formed on one of the two lateral surfaces of the disk element 23 as a guide channel 24, open on one side (see FIGS. 12 and 18, by way of example), for guiding the movement projection 14 when the locking device 8 is in its normal operating position. The guide channel 24 extends on the lateral surface of the disk element 23, offset to its center.
(32) FIGS. 10 and 15 each show a state of the door handle assembly 3, in which the locking device 8 is disposed in its normal operating position, and the coupling device 7 is in the rest position, due to the operating handle 4 not being actuated. The movement projection 14 of the locking device 8 is disposed in the normal operating position, outside of the guide channel 24 when the operating handle 4 is not actuated. In the state shown in FIGS. 10 and 15, the movement cavity 15, designed as a guide channel 24 that is open on one side, is disposed in the movement path of the movement projection 14, such that the movement projection 14 is moved toward the open side of the movement cavity 15, or the guide channel 24, respectively, when the operating handle 4 is actuated. In the state shown in FIG. 16, the operating handle 4 is completely actuated, such that the coupling device 7 is pivoted about its point of rotation 20, about the Z axis of the door handle assembly 3. In this state of the coupling device 7, the movement projection 14 is also pivoted, such that this movement projection is now disposed within the guide channel 24. To the extent that no large acceleration forces act on the door handle assembly 3, and the operating handle 4 is actuated, the actuation projection 14 is moved into the guide channel 24. As soon as the user releases the operating handle 4, the coupling device 7 is pivoted back into the position shown in FIG. 15, as a result of the spring tension, which forces the coupling device 7 into the rest position, as a result of which, the movement projection 14 is again moved out of the guide channel 24.
(33) FIGS. 17 and 18 show the other states of the door handle assembly 3 according to the second embodiment, in which an acceleration force acts on the locking device 8, such that the locking device 8 is moved out of the normal operating position, and is then located in one of the respective blocking positions. The locking device 8 is rotatably supported on the handle mounting 6 by means of a pivot axle 18, such that it can rotate about the Z axis of the door handle assembly 3, and likewise has a mass weight 19, wherein the locking device 8 is rotatably supported at its center by means of the pivot axle 18. In that the mass weight 19 is disposed offset to the pivot axle 18, the locking device 8 is moved out of its normal operating position by the effects of an acceleration force, wherein the movement in the first or second blocking direction 21, 22 is also a rotational movement about the pivot axle 18 in the second embodiment, and the locking device 8 swings about the pivot axle 18 during a vehicle accident, until it is deflected by the oscillations caused by the acceleration force. In FIG. 17, the locking device 8 is rotated 285 about the pivot axle 18 (Z axis) as the result of the effects of an acceleration force in the first blocking direction 21 (see arrow 21 in FIG. 17), such that the movement cavity 15, designed in the manner of a blind hole, i.e. the guide channel 24, is now no longer in the movement path of the movement projection 14. In FIG. 18, in contrast, the locking device 8 is rotated +285 about the pivot axle (Z axis) as a result of the effects of an acceleration force, or as a result of a swinging movement, in the second blocking direction 22 (see arrow 22 in FIG. 18), by means of which the guide channel 24, or the movement cavity 15, respectively, is then no longer in the movement path of the movement projection 14. An actuation of the operating handle 4 or a pivoting of the coupling device 7, which is rotatably supported on the handle mounting 6, such that it can rotate about its axle journals 11, is then blocked in FIGS. 17 and 8 as a result of the rotation of the locking device 8 about the pivot axle 18, because the movement projection 14 can no longer enter the guide channel 24, or move into this guide channel, respectively, due to the rotation of the coupling device 7. Instead, the movement projection 14 hits a contact surface 25, having the shape of a segment of a circle, which is formed on the lateral surface of the disk-shaped locking device 8 lying opposite the mass 19. With the second embodiment of the door handle assembly 3, which FIGS. 10-18 relate to, the pivot axle 18 of the locking device 8 is oriented substantially parallel to the point of rotation 20 of the coupling device 7, in order to obtain the desired blocking of the operating handle 4, or the coupling device 7, when acted on by an acceleration force. Alternatively to rotating at the rotational angle of 285 about the locking device 8 in FIGS. 17 and 18, from the normal operating position, as a result of the effects of an acceleration force in the first or second blocking direction 21, 22, a smaller rotational angle is also conceivable.
(34) Both the first as well as the second embodiment of the door handle assembly 3, or 3, respectively, have at least one mechanical return element 26. The mechanical return element 26 (see FIGS. 3 and 11, by way of example) exerts a force that forces the locking device 8, 8 into the normal operating position, such that this does not presently concern a locking device that locks in position, but rather, it concerns a locking device that returns to its starting position. By way of example, the mechanical return element 26 can comprise an elastic spring element 27, as is depicted in the two embodiments. The respective spring element 27 is supported at both ends, on both a projection 28 of the handle mounting 6, that is fixed in place, as well as on a contact surface 29 that moves together with the locking element 8, 8 (see FIGS. 5 and 14). With a movement of the locking device 8, 8 in the first or second blocking direction 21, 22 as a result of the effects of an acceleration force, the contact surface 29 moves in relation to the projection 28 against the force of the elastic spring element 27, in that one of the two ends of the spring element 27 is deflected. In order that the locking device 8, 8 does not already rotate into a blocking position during smaller vibrations, the mechanical return element 26, or the spring element 27, respectively, is designed such that it retains the locking device 8, 8 in the normal operating position, until an acceleration force of at least 7 g has been applied.
(35) In summary, with the present invention, a door handle assembly 3, 3 having a non-locking locking device 8, 8 is provided, which is distinguished by a secure activation, and which securely blocks the operating handle 4, or the coupling device 7, 7, respectively, even with oscillations resulting form the effects of acceleration forces. This is enabled according to the invention in that the locking device 8, 8 can rotate at least 90 about its pivot axle 18, 18, such that swinging movements in both directions, i.e. rotational movements in opposite directions, by the locking device 8, 8 are possible. With the door handle assemblies known from the prior art, the path for the deflection of the locking device, in order to move it into the movement path of the coupling device, is too small, which leads to situations in practice, in which the locking device moves back, after its deflection, as a result of oscillations, in an abrupt manner, and the coupling device is not blocked at times, which leads to an undesired actuation of the closing assembly and opening of the door. This danger is no longer present with the present invention, because the locking device 8, 8 has a greater path to travel when activated, which is defined by the rotational movement as at least 90 about the pivot axle 18, 18. Furthermore, the locking device 8, 8 can move in two opposing blocking directions, such that a blocking of the operating handle 4, or the coupling device 7, 7, respectively, is provided, even during a swinging of the locking device 8, 8 in both directions. According to a first embodiment, the pivot axle 18 of the locking device 8 is oriented substantially transverse to the point of rotation 20 of the coupling device 7, whereas, with the second embodiment, the pivot axle 18 of the locking device 8 is oriented substantially parallel to the point of rotation 20 of the coupling device 7. This configuration guarantees an activation of the locking device 8, 8 with effective acceleration forces, which act laterally on the motor vehicle in the interior of the vehicle or in the opposite direction (Y axis).
(36) The invention described above is, as a matter of course, not limited to the embodiments described and depicted herein. It is evident that numerous modifications, obvious to the person skilled in the art with regard to the intended use, can be made to the embodiments depicted in the drawings, without abandoning the field of the invention thereby. All that is contained in the description and/or depicted in the drawings, including that which deviates from the concrete embodiment examples, which is obvious to the person skilled in the art, belongs to the invention thereby.
