Abstract
A locking device for a motor vehicle includes an actuating lever, a lock and at least one Bowden cable, which is arranged between the actuating lever and the lock, wherein the lock can be actuated by means of the actuating lever and with the help of the Bowden cable and a functional unit, which is arranged on the Bowden cable and has an electric drive, and wherein the lock can be actuated by means of the functional unit at least in an assisting manner or an actuation can be prevented.
Claims14
A locking device for a motor vehicle comprising:
- an actuating lever;
- a lock;
- a Bowden cable which is arranged between the actuating lever and the lock, wherein the lock is configured to be actuated by the actuating lever and the Bowden cable;
- and
- a functional unit which is arranged on the Bowden cable and has an electric drive, wherein the lock is configured to be actuated by the functional unit, at least in an assisting manner, or an actuation of the lock is configured to be prevented by the functional unit,
- wherein the functional unit includes at least one deflection unit configured to deflect the Bowden cable,
- wherein the functional unit includes a drive element and a drive configured to activate the at least one deflection unit, wherein the drive is a gear stage connected between the electric drive and the drive element;
- wherein the at least one deflection unit includes a first deflection unit connected to a first part of the Bowden cable and a second deflection unit connected to a second part of the Bowden cable, wherein the first deflection unit and the second deflection unit are configured to be activated by the drive element;
- wherein the first deflection unit and the second deflection unit are rotatably mounted on a common central axle and are coupled by a coupling element, whereby the second deflection unit is actuated by rotation of the first deflection unit via the coupling element;
- and
- wherein the functional unit further includes a switching device that provides a control signal to the electric drive, wherein the second deflection unit includes a contour that actuates the switching device when the second deflection unit is actuated.
