Description

[0030] In the drawings:

[0031] FIG. 1 shows a first possible embodiment of a motor vehicle latching system according to the invention comprising a first possible embodiment of a door handle module according to the invention,

[0032] FIG. 2 shows a further possible embodiment of a door handle module according to the invention,

[0033] FIG. 3 shows a further possible embodiment of a door handle module according to the invention, and

[0034] FIG. 4 shows a motor vehicle comprising a motor vehicle latching system according to the invention.

[0035] FIG. 1 describes a motor vehicle latching system according to the invention comprising a door handle module according to the invention, in a first embodiment. In this case, the door handle module 10 is mounted on a movable part 110. The movable part 110 comprises a shell 111, the handle support 11 of the door handle module 10 being mounted on the shell 111 of the movable part 110. In this case, the handle support 11 is arranged around a door handle cup 40 on the shell 111 of the movable part 110. The door handle cup 40 thus makes it possible for a hand or a finger 51 of a user to engage in the door handle cup, and for the handle 12 to be controlled by a finger 51 of a user. For this purpose, the handle 12 comprises a hinge pin 12.1, the handle 12 being able to be pivoted, in FIG. 1, by the finger 51, in parallel with the shell 111. In FIG. 1, this means that the handle 12 is designed as a lever and can be pivoted to the right or to the left, about the hinge pin 12.1, in the plan view in FIG. 1. The handle 12 is connected to an operating mechanism 13, the operating mechanism consisting of a lever arm and a Bowden cable. By means of operation, i.e. pivoting, of the lever 12, a lever arm 13 is now operated such that a Bowden cable 13 is moved by the lever arm 13. In this case, the Bowden cable 13 is connected to the latch 20, such that mechanical operation of the latch by the user is possible. The handle, in this case the lever 12, is concealed by the shell 111 at least in portions.

[0036] Furthermore, FIG. 1 shows a receptacle 17 for a locking cylinder 17.1 on the handle support 11 of the door handle module. In this case, the locking cylinder 17 and the locking cylinder receptacle 17.1 are arranged in the door handle cup 40 such that this is concealed, at least in portions, by the shell 111 of the movable part 110. In the case of normal operation of the door handle module, i.e. when a user approaches the movable part, for example a door, the locking cylinder 17.1 cannot be identified.

[0037] Furthermore, FIG. 1 shows a sensor unit 14 on the door handle module 10, comprising a sensor element 15. In FIG. 1, the sensor unit 14 is provided with an elongate sensor element 15, such that engagement therein or a touch by a finger 51 of a user can be identified. Furthermore, FIG. 1 shows a power connection 70 which faces out of the door handle cup 40.

[0038] The movable part is shown as a side door or passenger door, but, within the spirit and scope of the present invention, any vehicle door, including swing doors or tailgates, engine covers, side sliding doors, tail lifts, or the like, can be envisaged.

[0039] FIG. 2 shows a further embodiment of a door handle module according to the invention. In this case, the door handle module 10 is arranged on a shell 111 of a movable part 110, having a toward the handle support 11. In FIGS. 1 and 2, the movable part 110 is shown schematically as a door of a motor vehicle. A door handle cup 40 is arranged on the movable part 110, which cup is formed as a concave recess in the movable part 110. This makes it possible for a user to insert a hand into the door handle cup 40. The hand can then be moved in the operating region 30, as a result of which electrical/electronic and/or electromechanical or purely mechanical operation can take place. For this purpose, the door handle module 10 comprises a handle 12 which is arranged so as to be movable about a hinge pin 12.1.

[0040] In FIG. 2, the handle 12 is rotatable about the hinge pin 12.1 such that the user can move the handle 12 toward or away from him, and thus pivot it about the hinge pin 12. Furthermore, the handle is substantially entirely concealed by the shell 111. This means that the user can simply grasp inside the door handle cup 40 from below, in order to operate the handle. Therefore, the handle is substantially, i.e. in normal use, not visible from the outside of the vehicle. As a result, an optically improved appearance of the vehicle, in particular of the shell, is made possible.

[0041] For electronic or electromechanical operation, the handle 12 comprises a sensor unit 14 which is arranged in the handle 12. As a result, a user intention can be identified by the sensor unit 14 being approached or the handle 12 being touched. Furthermore, mechanical pivoting of the handle 12 about the pin 12.1 can achieve purely mechanical operation. For this purpose, an operating mechanism 13 in the form of a lever is arranged on the handle 12. In this case, the lever can be mechanically connected to the latch for example by means of a Bowden cable or a further lever.

[0042] The handle 12 is bidirectionally operable and is connected to a bidirectionally acting operating mechanism 13. Accordingly, the handle 12 can be moved in a first operating direction x and a second y which opposes the first operating direction. It is thus possible for opening of a latch to be achieved in a first operating direction x, and for closure of a latch to be achieved in a second opposing operating direction y. The first operating direction x is directed orthogonally away from the vehicle shell 111, and the second opposing operating direction y is directed toward the vehicle shell 111, such that, as a result of an accident and an associated unintended action of force, for example by deformation of the shell, on the handle 12, the handle 12 is operated in the closing direction. This makes it possible to prevent the latch of a movable part from being able to be opened or unlocked.

[0043] FIG. 3 shows a further embodiment of a door handle module 10 according to the invention. In this case, too, the door handle module 10 is mounted on a shell 111 of a movable part. In this case, the handle 12 is mounted so as to be rotatable or pivotable about a pin 12.1. It is thus possible for a user to pivot the handle 12 about the pin 12.1 by means of a finger 51, for example by pulling or pushing. Furthermore, at least one spring 12.2, in particular a double torsion spring 12.2, is arranged on the pin 12.1 of the handle 12. This allows for automatic, i.e. independent, movement of the handle 12 into the original position thereof. A sensor unit 14 is arranged on the handle 12, such that it is possible to detect, by sensor means, a finger 51 approaching or touching the handle 12.

[0044] In FIG. 3, too, the handle is substantially entirely concealed by the shell 111. This means that the user can simply grasp inside the door handle cup 40 from below, in order to operate the handle 12. Therefore, the handle 12 is substantially, i.e. in normal use, not visible from the outside of the vehicle. As a result, an optically improved appearance of the vehicle, in particular of the shell 111, is made possible.

[0045] FIG. 4 shows a vehicle 100 comprising a movable part 110 and a motor vehicle latching system 200 and a door handle module 10 according to the invention.

[0046] The above explanation of the embodiments describes the present invention exclusively within the context of examples. Of course, individual features of the embodiments can, if technically expedient, be freely combined with one another, without departing from the scope of the present invention.
