Definitions
- Motor vehicle lock especially motor vehicle door lock
- the locking mechanism essentially consists of a rotary latch and a pawl designed as a single-latch locking mechanism, i.e. H. has a (single) pawl.
- the invention also includes so-called multi-pawl locks with two pawls.
- the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that simplifications in terms of design and production compared to the prior art are observed.
- a generic motor vehicle lock and in particular a motor vehicle door lock within the scope of the invention is characterized in that a single and combined opening/closing drive is implemented, which can be applied to the drive pawl either in an opening direction to act on the pawl and in an opposite closing direction to act on the rotary latch.
- the invention therefore no longer relies on a closing drive and, separately from this, an opening drive for the locking mechanism two electric motor drives. Rather, according to the invention, a single electric motor drive is used, namely the single and combined opening/closing drive. With the help of this combined opening/closing drive, the desired locking opening as well as a closing process is realized and implemented.
- the invention works with the single and combined opening-closing drive, which is acted upon on the one hand in the opening direction and on the other hand in the oppositely directed closing direction.
- the opening/closing drive in conjunction with the drive pawl ensures that the pawl is lifted from its locking engagement with the rotary latch.
- the rotary latch can then open with spring support and releases a previously caught locking bolt.
- This is connected to an electric motor opening drive.
- the single and combined opening/closing drive in the closing direction opposite to the opening direction is able to apply a closing force to the rotary latch via the drive pawl.
- the drive pawl has a connection either to the pawl or the rotary latch working boom.
- the procedure is usually such that a toothed segment of the drive pawl and the arm are arranged at an angular distance from one another.
- the drive pawl Due to the angular distance of the toothed segment from the drive pawl, any functional impairments when acting on the drive pawl using the combined opening/closing drive are avoided from the outset.
- the further fact that the drive pawl is generally pot-shaped in cross section with a central axis of rotation and a toothed segment on the circumference as well as an arm also contributes to this.
- the pot-like design of the drive pawl in cross section takes into account the fact that the drive pawl is usually additionally equipped with a contour for interaction with a sensor that interrogates the angular position of the drive pawl.
- the contour is typically found on a cylinder stub, which can be connected to the drive pawl (rotatably) or is designed in one piece with it.
- the cylinder stub not only defines the central axis of rotation of the drive pawl, but is also equipped with the required contour on its outer circumference, which can be queried using the sensor in order to be able to determine the angular position of the drive pawl.
- the drive pawl can engage over the cylinder stub in question, so that both the circumferential toothed segment and the boom are displaced into an associated plane spanned by the locking mechanism.
- the additional and advantageous procedure is that the arm of the drive pawl is arranged in an unloaded state in a parking area that does not act on either the pawl or the rotary latch.
- the parking area can be detected using the sensor.
- additional stops, rubber buffers, etc. for the drive pawl are expressly unnecessary.
- the interplay between the contour on the cylinder stub on the one hand and the sensor querying the contour on the other hand ensures that the drive pawl occupies the parking area in question in its unloaded state. This is deliberately a position range of the drive pawl in an unloaded state, which takes any external influences into account.
- the basic position assumed by the drive pawl in the unactuated state depends on factors such as the voltage acting on the opening/closing drive, the temperature or even the direction in which the drive pawl is acted upon, i.e. H. whether it assumes its basic position coming from the opening direction or coming from the closing direction. Either way, the parking area is expressly and according to the invention permitted and recorded using the sensor. This corresponds to a position range and consequently an angular range of the drive pawl, which it can assume in its basic position. This makes additional stops, stoppers, etc. unnecessary, which also helps reduce weight, manufacturing costs and price.
- the drive pawl is advantageously designed as a metal molding or plastic molding also contributes to this.
- the drive pawl on the one hand and the cylinder stub on the other hand can be designed in two parts. As a rule, however, it is a one-piece plastic molding or metal molding. Both the metal molding and the plastic molding can be designed as injection molded parts.
- a motor vehicle lock and in particular a motor vehicle door lock which is structurally strikingly simple Way is able to ensure both an electric motor opening of the locking mechanism and its closing.
- This can be attributed to the fact that a single combined opening/closing drive is responsible for both processes.
- the different directions of rotation of the combined opening/closing drive are used to act on the drive pawl in the opening device on the one hand and in the opposite closing device on the other hand. This is where the main advantages can be seen.
- FIGS 1 to 3 show the motor vehicle lock according to the invention in different views.
- the figures show a motor vehicle lock and in particular a motor vehicle door lock.
- this has a locking mechanism 1, 2 essentially consisting of a rotary latch 1 and a pawl 2.
- the locking mechanism 1, 2 is stored in a lock housing 3, which is or may be made largely of plastic.
- the basic structure includes a closing drive 4 and an opening drive 4 for the already mentioned locking mechanism 1, 2, with a single and combined opening/closing drive 4 being implemented according to the exemplary embodiment and according to the invention.
- a drive pawl 5 is provided, with the help of which the rotary latch 1 or the locking mechanism 1, 2 can be acted upon.
- the drive pawl 5 can either be in an opening direction ⁇ to act on the pawl 2 and in an opposite direction Closing direction Z can be controlled to act on the rotary latch 1. This can best be seen from FIG. 1, where on the one hand the opening direction ⁇ and on the other hand the closing direction Z are shown.
- the opening direction ⁇ corresponds to a pivoting movement of the drive pawl 5 about its axis 6 in the counterclockwise direction
- the closing direction Z of the drive pawl 5 corresponds to a rotation of the drive pawl 5 about its axis 6 in the clockwise direction
- the drive pawl 5 is equipped with teeth 5a.
- the toothing 5a serves to engage a gear 4 of the combined and single opening/closing drive 4.
- the gear 4 and the opening/closing drive 4 coincide in design.
- the opening/closing drive 4 may also have an electric motor and an intermediate gear in addition to the gear 4, which is not shown in detail for the sake of a better and clearer representation.
- the drive pawl 5 is a toothed segment wheel that can be rotated about the axis 6. This can be attributed to the fact that the toothing 5a in connection with the circular drive pawl 5 is only realized and provided on a peripheral segment of the drive pawl 5. Consequently, a tooth segment 5a is observed. In fact, the drive pawl 5 also has an arm 5b which acts either on the pawl 2 or the rotary latch 1.
- the toothed segment 5a of the drive pawl 5 and the arm 5b are arranged at an angular distance from one another.
- an angular distance a in the range of observed at approximately 90°, which is of course only an example and not a limitation.
- an edge of the toothed segment 5a and the arm 5b are spaced apart from one another. In this way, any mutual functional impairments are ruled out.
- the drive pawl 5 is pot-shaped in cross section with the central axis of rotation 6 and the peripheral toothed segment 5a and the arm 5b.
- the design is carried out in detail in such a way that the drive pawl 5 rests on a cylinder stub 7, which can largely be seen in FIG. 2, or is coupled in a rotationally fixed manner to this cylinder stub 7 with a common definition of the axis of rotation 6.
- the cylinder stub 7 has a contour 8 on its outer circumference, which is set up to interact with a sensor 9.
- the sensor 9 is a switch and in particular a microswitch.
- the angular position of the drive pawl 5 can be queried using the sensor or microswitch 9.
- the boom 5b can be arranged as part of the drive pawl 5 in an unloaded state in a parking area P, which is shown schematically in FIG. 3.
- This parking area P belongs to a possible angular position or an angular range which the arm 5b of the drive pawl 5 can sweep over, without the pawl 2 or the rotary latch 1 being acted upon in the basic state shown in FIG.
- the parking area P takes into account any variations when the boom 5b assumes the basic position. Such variations can be attributed to fluctuating voltages acting on the opening/closing drive 4, temperature differences or even to the fact that the basic position 3 is approached starting from the opening direction ⁇ or the closing direction Z.
- the use of the parking area P by the boom 5b of the drive pawl 5 creates the possibility that any stops, stop buffers, etc. for the drive pawl 5 are unnecessary overall. This reduces the design effort and manufacturing costs.
- the sensor 9 or microswitch therefore emits a consistently identical parking signal or sensor signal to a control unit, not expressly shown, for evaluating the drive movement of the opening/closing drive 4.
- the drive pawl 5 is then returned to its basic position or the parking area P. This corresponds to a movement of the drive pawl 5 in a counterclockwise direction.
- loading the boom 5b in the opening direction ⁇ results in the boom 5b being pivoted in the counterclockwise direction.
- the boom 5b moves against a stop contour of the pawl 2 and ensures that the pawl 2 is pivoted clockwise about its axis in the exemplary embodiment.
- the clockwise movement of the pawl 2 in comparison to the rotary latch 1 now results in the pawl 2 leaving its locking position in relation to the rotary latch 1.
- the rotary latch 1 spring-supported
- the lock 1, 2 is therefore opened. The same applies to the associated motor vehicle door.
