Description

Vehicle locking devices, especially vehicle boot locking devices The present invention relates to a vehicle locking device, in particular, a vehicle door locking device and preferably a vehicle boot locking device, comprising a locking mechanism substantially comprising a rotary latch and a pawl, and comprising a motor drive for the pawl, wherein the rotary latch has a rotary latch bearing pin fixed to a locking device case, and the pawl has a pawl bearing pin for rotatably mounting each about an associated axis. Vehicle locking devices generally refer to locking devices located inside or on a vehicle. Vehicle locking devices include not only vehicle door locks but also, for example, locks for vehicle seats, flap locks such as tank flap locks, or loading flap locks. Additionally, vehicle locking devices include specialized vehicle door locks such as vehicle bonnet locks or vehicle boot locks. Particularly in the case of vehicle boot locks, so-called electric locks are used almost exclusively; in such locks, the locking mechanism, consisting of a rotary latch and a pawl, is opened by a motor while in a closed state by a motor drive. To this end, the motor drive generally operates on a pawl, particularly as described in WO 00/47851 A1. For this purpose, the motor drive is equipped with an electric motor and an output worm on the output shaft of the electric motor. Due to the output worm, a driven pulley engaged with the worm acts in a rotary manner. Subsequently, the driven pulley ensures that the pawl is lifted from the engagement state with the rotary latch when the locking mechanism is in the closed state. General modern technology according to DE 195 05 779 A1 proceeds in a similar manner. In this case as well, the pawl is lifted from the engagement state with the rotary latch by a driven pulley, which is a component of the motor drive. To this end, the pawl is secured within or on the lock case by an associated bearing pin, similar to the rotary latch. In other words, to open the locking mechanism, in both cases, the pawl needs to rotate about an axis defined in such a way that it is secured to the lock case. Although known procedures have proven themselves in principle, there is still room for improvement, particularly after adverse operating conditions and/or prolonged operation. Thus, rotational movement of the pole around a fixed axis inevitably implies that the pole's associated locking face or lug slides along the corresponding locking face or lug on the rotary latch. Since the two steel faces typically move relative to each other at this point for reasons of safety and strength, there is some degree of distinct friction. If additional dirt or dust has infiltrated at this point due to wear or long service life, or if rust is observed, an overall adverse friction condition is observed. In this case, potential for improvement is provided in conjunction with the additional fact that increasingly smaller motors are required as components of motor drives today to keep cost and weight low. Accordingly, the present invention is based on the technical problem of further developing such a vehicle locking device, particularly a vehicle door locking device, preferably a vehicle boot locking device, in such a way that the electric opening of the locking mechanism can be performed with less force than the latest technology, starting from the closed state of the locking mechanism. To solve these technical problems, a general vehicle lock is characterized within the scope of the present invention in that a pawl bearing pin is mounted on the actuating rocker of a motor drive and consequently is not mounted in or on the lock case. Accordingly, the actuating rocker is rotatably mounted around a rocker bearing pin fixed to the lock case. In this way, the present invention ensures that the pawl not only rotates around its axis to release, for example, a rotary latch, but also that the axis may be displaced by a variable distance by the actuating rocker relative to a fixed rotary latch. First, the present invention eliminates the fixed mounting of a pole by a pole bearing pin within or on the lock case. Rather, the actuation rocker is used as a component of a motor drive to accommodate the pole bearing pin and, accordingly, to rotatably mount the pole around an axis defined by the pole bearing pin. To perform this role, the actuation rocker is rotatably mounted around a rocker bearing pin fixed to the lock case. As a result, rotational movement of the actuation rocker around the axis defined by the rocker bearing pin causes the axis of the pole located on the actuation rocker to be simultaneously displaced. In this way, the axis of the pole, whose axis is defined by the pole bearing pin of the actuation rocker, can be displaced by a variable distance compared to a fixed rotary latch. The possibility opened according to the present invention, which not only designs the pawl to be rotatable with respect to a fixed rotary
