Definitions
- the invention is based on the technical problem of further developing such a closing device in such a way that an embodiment for emergency unlocking and thus emergency opening that is both structurally simple and cost-effective is made available while the effectiveness remains unchanged.
- an emergency unlocking is implemented purely mechanically and a complex sensory solution is expressly dispensed with.
- the handle ensures that the power flow from the electric motor via the gearbox to the rotary latch is interrupted quite simply and mechanically without a sensor query. Because the handle ensures that the power flow element is disengaged as part of the transmission.
- the handle in question can typically be acted upon from inside the vehicle or from a trunk and is generally designed and designed as an emergency release handle.
- the resultant emergency unlocking of the motor vehicle lock according to the invention allows the motor vehicle lock to be opened subsequently or in one go. The same applies to a tailgate advantageously equipped with this. Because the closing device according to the invention for a motor vehicle lock is generally and advantageously a closing device for a Tailgate lock or the subject of the invention is such a tailgate lock.
- the design is further such that the handle is accessible when the door or the motor vehicle lock belonging to the motor vehicle door is open or from the interior, so that a user can act on the handle for emergency unlocking.
- the design and mechanical connection of the handle is particularly simple and advantageous because the handle is mounted on the lock housing.
- the handle is designed in one piece. This can be implemented particularly easily in that the handle is advantageously a plastic injection-molded part.
- the handle is advantageously a plastic injection-molded part.
- the procedure is usually such that the loading arm and the ratchet arm represent a part of the handle, which is usually non-rotatably coupled to the other second part in the form of the element arm during the installation of the handle and its mounting on the lock housing.
- corresponding tooth and opposing tooth formations can be coupled to one another in a torque-proof manner.
- the handle is usually designed in such a way that the force flow element is loaded linearly with its help.
- the linear loading of the power flow element ensures in a simple manner that the power flow element interrupts the power flow within the transmission.
- the power flow element is typically a gearwheel element which, as a rule and when the handle is not applied, assumes its engaged position as part of the transmission and is consequently integrated into the power flow of the transmission.
- the disengaged position of the power flow element or gear element corresponds to the relevant gear element being disengaged from its adjacent gears, so that the power flow inside the transmission is interrupted as a result.
- the force flow element can additionally or alternatively also be a clutch element.
- the power flow element or gearwheel element is prestressed in its engaged position with the aid of a spring. That is, the spring ensures that the force flow element assumes its engaged position. Consequently, in order to convert the power flow element into its disengaged position using the handle, the force of the spring must be overcome using the handle.
- a closing device is made available that enables an emergency unlocking of the associated motor vehicle lock and, in principle, also an effective interruption of the closing process, but instead provides a structurally astonishingly simple and cost-effective mechanical solution.
- the power flow element which can be engaged and disengaged as desired, is provided as part of the transmission.
- the handle mounted on the lock housing.
- the handle can easily be adapted to differently designed lock housings and specific requirements. Additional equipment such as sensors, motors, etc. are expressly unnecessary. Rather, a simple mechanical solution is provided. This is where the main advantages can be seen.
- FIG. 1 shows the closing device according to the invention in an overview
- FIG 4 shows the closing device with the housing open, in another modified embodiment.
- a closing device is shown in the figures, specifically for a motor vehicle lock or motor vehicle door lock, which is reproduced only in part. This is advantageously a tailgate lock.
- a motor vehicle door lock closing aid is described in more detail overall and is illustrated.
- the motor vehicle door lock has to for this purpose in its basic structure via a locking mechanism 1, 2 consisting essentially of rotary latch 1 and pawl 2, which can be seen in FIG. 1 only rudimentarily.
- the locking mechanism 1 , 2 is rotatably mounted in a lock case 3 .
- a lock housing 4 made of plastic encloses the illustrated motor vehicle lock or motor vehicle door lock.
- the closing device has an electric motor 5 and a gear 6, 7, 8, 9 following the electric motor 5.
- the gear 6, 7, 8, 9 consists of a first gear element that meshes with the output shaft of the electric motor 5 6 and a second gear element 7 together.
- the two transmission elements 6, 7 can be gears which are offset from one another according to the exemplary embodiment.
- a power flow element 8 which is a gear element in the context of the illustration according to FIGS.
- the force flow element 8 in the variant according to FIG. 4 is designed as a coupling element.
- the power flow element 8 is part of the gear 6, 7, 8, 9 and couples the first and second gear element 6,7 to an output-side gear element 9, which, according to the exemplary embodiment, is a drive pawl that works directly or indirectly on the rotary latch 1 acts. That is, rotational movements of the output-side transmission element or the drive pawl 9 ensure that the rotary latch 1 is pivoted from, for example, a pre-locked position into the main locked position, and consequently a motor vehicle door (not shown) is pulled shut.
- the transmission 6, 7, 8, 9 works at least during such a closing process on the rotary latch 1.
- a continuous power flow from the electric motor 5 via the transmission 6, 7, 8, 9 to the rotary latch 1 is observed.
- the closing device or the transmission 6, 7, 8, 9 could also work on a locking bolt, for example, which is not shown.
- the motor vehicle door in question and not expressly shown is equipped with the door-fixed locking bolt, which is caught by the rotary latch 1 (in the pre-locked position) and follows the described closing movement of the rotary latch 1 from the pre-locked position to the main locked position.
- the motor vehicle door in question is pulled shut and a gap between the motor vehicle door and a motor vehicle body is closed.
- the invention provides an emergency unlocking mechanism to be described below.
- a handle 10 mounted on the lock housing 4 is provided for mechanically interrupting the closing process.
- the handle 10 acts on the power flow element 8, which can be engaged and disengaged as described above, as part of the transmission 6, 7, 8, 9.
- the handle 10 generally works linearly on the power flow element 8 and ensures that in the disengaged and dash-dotted line State a mechanical connection between the power flow element 8 and the upstream gear elements 6, 7 on the one hand and the drive pawl 9 on the other hand is interrupted.
- the handle 10 is acted upon as shown in FIG. 2 about its axis 11 relative to the lock housing 4 in the counterclockwise direction indicated there.
- a bolt or pin is provided in or on the lock housing 4, which defines the axis 11 for the rotatable mounting of the handle 10 on the lock housing 4.
- the bolt or pin can be part of the lock housing 4 designed as a plastic injection molded part.
- the handle 10 can be designed in one piece overall, as shown in FIG.
- a multi-part design corresponding to the exemplary embodiment according to FIGS. 1 to 3 is also conceivable.
- part of the handle is formed jointly by the ratchet arm 10b and the urging arm 10c, while the other part of the multi-part and in this case two-part handle 10 is defined by the element arm 10a.
- Both parts of the multi-part or two-part handle 10 can be coupled to one another in a rotationally test during assembly on the lock housing 4 .
- the pin connected to one component of the handle 10 engages the other component of the handle 10 in a rotationally fixed manner.
- an opening in the lock housing 4 is passed through to define the axis 11 .
- the force flow element 8 is prestressed in its engaged, full position by means of a spring 12, 13.
- the spring 12, 13 is a spiral spring 12 which surrounds a guide pin 8a of the force flow element 8.
- the design is such that the force flow element 8 is guided in its linear direction via the guide pin 8a and consequently in the disengaged state can reach through a corresponding opening 3a provided in the lock case 3 .
- the coupling element or force flow element 8 ensures that the second transmission element 7 and the drive pawl 9 are mechanically coupled to one another in its engaged state.
- the electric motor 5 can work on the rotary latch 1 via the gear 6, 7, 8, 9 and act on it in a pulling sense, as has already been described in the introduction.
- the handle 10 on the actuating arm 10c is acted upon by an operator (counterclockwise), so that as a result the force flow element 8 or clutch element is disengaged.
- the power flow from the electric motor 5 via the gear 6, 7, 8, 9 to the rotary latch 1 is interrupted and the rotary latch 1 can in turn be pivoted together with the locking bolt caught by it.
- the pawl arm 10b of the handle 10 ensures that the pawl 2 cannot engage with the rotary latch 1 during this process, but rather is lifted off the rotary latch 1 .
