Description

[0026] In the figures:

[0027] FIG. 1 shows a three-dimensional view of a motor vehicle lock and a view of the inlet region of the motor vehicle lock with a rotary latch located therein; and

[0028] FIG. 2 shows a cross section through the motor vehicle lock shown in FIG. 1 according to line II-II, wherein a section through the actuation means and the energy store is shown.

[0029] FIG. 1 shows a motor vehicle lock 1 in a three-dimensional view of a part of the motor vehicle lock housing 2 and a part of a lock case. The lock case 3 is connected to a motor vehicle door element (not shown) by means of screws 4, 5, 6. The motor vehicle lock shown can be, for example, a side door lock. The lock case 3, which is preferably made of metal, surrounds an inlet region 7 of the motor vehicle lock 1, wherein a rotary latch 8 in a closed position is shown in the inlet region 7. An actuation means 10 is integrated and flush with a plane 9 of the inlet region 7. The actuation means 10 has an opening in the form of an insertion slot 11, wherein for example a tool or a keychain can be inserted into the insertion slot. Furthermore, FIG. 1 shows two axes for the locking mechanism 14 which are riveted to the lock case 3, wherein only the rotary latch 8 of the locking mechanism 14 can be seen in FIG. 1. In this exemplary embodiment, the locking mechanism is formed from the rotary latch 8 and the pawl 15.

[0030] FIG. 1 shows the motor vehicle lock 1 detached from the motor vehicle, wherein the rotary latch 9 and thus the locking mechanism 14 are in a latching position. If the locking mechanism 14 is opened, the rotary latch 8 releases the inlet region 7 by means of the fork-shaped opening 16 of the rotary latch 8. The operator can hence securely reach the insertion slot 11 of the actuation means 10 and actuate an emergency power supply. In this case, the actuation means 10 can be pivoted back and forth in the direction of the arrow P, depending on the embodiment of the motor vehicle lock 1, so that, for example, a child lock can be activated in one direction of rotation and, for example, the actuation means 10 can be screwed out of the lock housing 2 in another opposite direction of rotation. As described above, a locking function can be provided for this purpose in the actuation means 10 and/or lock housing 2 in order to realize a secure positioning of the actuation means in the motor vehicle lock 1 and to provide the operator with haptic feedback for a secure positioning of the actuation means 10.

[0031] FIG. 2 now shows a section through the motor vehicle lock 1 along the line II-II of FIG. 1. A section through the lock housing 2, the lock case 3, the screws 4, 6, the inlet region 7, the actuation means 10 and the energy store 17 can be seen. As can be seen in FIG. 2, the actuation means 10 also serves to guide the energy store 17, wherein an extension 18 is formed on the actuation means 10 which surrounds the energy store and, in particular, an energy store housing 19. A spring element 20 is arranged between the actuation means 10 and the energy store 17 for the secure positioning of the energy store 17. In addition, the actuation means 10 has a shoulder 21 which forms, for example, a bayonet fitting for the actuation means 10 with the inlet region 7. The inlet region 7 and, in particular, the plane 9 of the inlet region can be designed as a separate component or formed integrally with the lock housing 2. In this exemplary embodiment, the actuation means 10 itself forms part of the energy store housing, wherein the actuation means 10 here serves as a housing cover for the energy store housing 19. A seal 22, for example a ring seal, is arranged between the actuation means 10 and the energy store housing 19. The energy store housing or battery compartment 19 can be protected reliably against external influences by means of the shoulder 21 and the seal 22.

[0032] The energy store 17 can be a battery, for example. Contacts 24, 25 are provided on an axial end 23 of the energy store 17, by means of which contacts the energy store 17 can be connected to, for example, conductor tracks of the motor vehicle lock. A power supply of the electrical components present in the motor vehicle lock and/or of a control unit in or outside the motor vehicle lock can thus be supplied with energy, i.e., current and voltage.

[0033] Now, if, for example, in the event of a power drop in the motor vehicle, there is no longer sufficient energy available to actuate the motor vehicle lock 1, an emergency power supply can be provided by means of the energy store 17. For this purpose, a control signal can be forwarded to the motor vehicle lock and/or to a controller. According to the invention, the energy store 17 is arranged in the motor vehicle lock 1 such as to be exchangeable. To exchange the energy store, the operator can, for example, insert a tool into the insertion slot 11 and release the actuation means 10 from engagement with the motor vehicle lock housing 2 or the plane 9 of the insertion region 7 and remove it so that the energy store 17 can be exchanged. After exchanging the energy store, for example a battery, the actuation means 10 can be reinserted into the lock housing and securely locked, wherein the shoulder 21 gets behind an insertion opening 28 for the actuation means 10. After closing the insertion opening 28 by means of the actuation means 10, the energy store 17 rests again securely against the conductor tracks 26, 27 of the motor vehicle lock also under pressure of the spring element 20.

[0034] According to the invention, it is also conceivable for the actuation means 10 to be designed such that an actuation mechanism 29 is formed on the actuation means 10, wherein the actuation mechanism 29 serves, for example, for activating a child lock. In this case, the actuation means 10 can, for example, engage in a form-fitting manner into the mechanism 29 or can consists of several parts. In this case, it is conceivable for the actuation means to, for example, engage with the energy store 19 such that the mechanism 29 can be moved by means of the actuation means 10.

[0035] The design of the motor vehicle lock 1 according to the invention makes it possible to exchange the energy store with the simplest structural means, wherein existing openings, i.e., the inlet region 7 of the motor vehicle lock 1, are used. On the one hand, a structurally favorable solution for providing an emergency power supply is thus made possible and, on the other hand, longevity of the motor vehicle lock can be ensured at any time.
