Definitions
- the invention relates to an electric motor drive for motor vehicle technical applications, in particular applications in and in a motor vehicle lock, with an electric motor, furthermore with a drive disk which can be acted upon by the electric motor and can be rotated about an axis, and with at least one spring associated with the drive.
- the drive is preferably an opening drive for the relevant motor vehicle lock.
- Electromotive drives for motor vehicle applications are typically operated with direct low voltage of, for example, 12 V, 24 V or even 48 V. For this reason, the drive power that can be represented with the help of the electric motor is limited, with which, for example, functional units are controlled via the electric motor drive. These functional units can generally be a window pane if the electromotive drive is designed as a window lifter drive. Of course, other applications and forms are also conceivable. In this way, the electric motor drive can provide seat adjustment, mirror adjustment, etc.
- Such electromotive drives are very particularly preferably used in and in motor vehicle locks.
- functional units such as individual levers are moved with the help of the drive pulley.
- different functional positions such as “locked”, “theft-proof” or “child-proof” can be approached.
- electric motor drives are advantageously used as opening drives inside motor vehicle locks.
- the electric motor drive or Opening drive directly or indirectly to a pawl as part of a locking mechanism made of rotary latch and pawl and ensures that the pawl is lifted from its engagement with the rotary latch. This can be done directly in that the drive pulley works directly on the pawl and lifts it out of its engagement with the catch.
- Such an electric motor drive is described and presented in the utility model DE 20 2012 001 961 U1 as an example and not as a limitation.
- the electric drive ensures that the locking mechanism consisting of the rotary latch and pawl is acted upon to open it electrically.
- a mechanical opening of the locking mechanism is provided at least in emergency operation.
- the drive pulley is equipped with an associated return spring.
- the return spring ensures that the electric drive returns to a neutral position after a release lever has been acted upon.
- the spring is a center-zero spring.
- a first return spring, a second return spring and, in addition, a third return spring are implemented in a comparable manner.
- the restoring springs ensure that the electromotive drive is returned to its basic position or neutral position after it has been deflected or moved.
- a drive wheel there includes a torque spring, which returns a gear wheel driven by the electric motor and the drive wheel to a specific angular position.
- the state of the art has basically proven itself when it comes to using the electric motor drive to act on individual functional units and to ensure that the associated spring resets them to a neutral position or basic position.
- the functional unit is a release lever which acts on the pawl of a locking mechanism or the pawl itself are large that the electric motor drive has difficulties or requires a voluminous and costly gear for a corresponding torque transmission.
- such increasing forces can be caused by changes in the closing force caused by aging, for example accompanied by hardening of rubber seals, increasing friction, etc.
- the invention as a whole aims to remedy this.
- the invention is based on the technical problem of further developing such an electromotive drive for motor vehicle applications in such a way that forces present due to construction or aging can be overcome in a structurally simple manner when the functional element or functional unit is actuated.
- the invention proposes in a generic electric motor drive that the spring transmits a force supporting the drive to the drive pulley.
- the spring is advantageously designed as a torsion spring.
- the design is usually such that the torsion spring in question is connected in a stationary manner with its coiled section to a pin, for example.
- the torsion spring interacts with its one drive leg with a contour on the drive pulley.
- the other leg or fixing leg of the leg spring rests against a stop.
- the drive limb can increasingly spread apart in relation to the fixing limb to support the drive in contact with the contour of the drive disk.
- Such a spreading of the drive leg relative to the fixing leg is observed and used according to the invention in the case when the drive pulley directly or indirectly Functional element or a functional unit applied.
- the electromotive drive for motor vehicle applications is an electromotive opening drive for a motor vehicle lock
- the opening process corresponds to the drive pulley working directly or indirectly on a pawl of a locking mechanism of the motor vehicle lock.
- the pawl With the help of the drive disk, the pawl is lifted from its latching engagement with the rotary latch in the closed position of the locking mechanism of the motor vehicle lock and as a result can swing open the (spring-assisted) rotary latch and release a previously caught locking bolt.
- this opening process of the electric motor drive is supported according to the invention by the force of the previously tensioned torsion spring.
- the said opening process or the direct or indirect actuation of the pawl as a functional element or functional unit usually corresponds to a certain rotational movement of the drive pulley (clockwise or counterclockwise).
- this movement of the drive disk to open the locking mechanism is now mechanically supported in that the torsion spring tensioned in a basic or neutral position releases its stored spring energy to the drive disk during the opening process and in this way additionally supports the electromotive actuating movement with spring energy.
- the drive arm resting against the contour of the drive pulley increasingly spreads apart relative to the stationary fixing arm.
- any door seal pressure can advantageously be overcome with the help of the electric motor drive and, in the example case, an opening drive for a motor vehicle lock, in a structurally simple manner and with a particularly inexpensive construction.
- the procedure according to the invention is not only suitable for overcoming high door seal loads, but can generally be used to support the electromotive drive when functional elements or functional units are applied. Because of the additional spring energy or clamping energy released via the spring, there is the possibility, for example, of using the electric motor with less power than before to interpret. It is also possible to dispense with complex and interposed gears between the electric motor and the drive pulley or the functional element or functional unit that is acted upon. As a result, the constructive and cost-related effort is reduced again.
- the spring provided at this point is already tensioned in the starting position or basic position or neutral position of the drive pulley, so that during the described opening process the tensioning energy or spring energy released in this way can be advantageously used to mechanically support the rotary movement of the drive pulley.
- the spring In order to tension the spring in the neutral or basic position, the spring is tensioned (again) each time the electric motor drive returns from its deflected position to the basic or neutral position. This is possible without any problems because any door sealing forces or door closing forces do not regularly have to be overcome during said return. Rather, a closing operation of an associated motor vehicle door is either carried out manually by a user or is carried out independently of the opening drive described in the example with the aid of an additionally provided closing drive.
- a mechanical energy accumulator is available which, starting from the basic position or neutral position of the electric motor drive, when the functional element or functional unit is acted upon, uses the energy made available by the electric motor drive through the clamping energy then released or spring energy supported.
- the detailed design is such that the drive pulley is circular with the axis for its rotation as the center.
- the already mentioned contour for the system of the drive arm of the torsion spring thereon runs concentrically compared to the Axis and arcuate, ie viewed over a specific and limited angle.
- the drive leg is advantageously equipped with an extension arm.
- the extension arm can interact with an additionally provided cam on the drive pulley to position the drive pulley.
- the cam is generally implemented in addition to the contour on the drive pulley.
- the cam can now interact with, for example, a bulge or recess in the extension arm of the drive arm.
- the drive pulley is thereby temporarily fixed in the desired position.
- an end position of the drive pulley or also the previously mentioned neutral position or basic position of the drive pulley can be predetermined mechanically.
- the bulge or recess on the extension arm acts as a latching contour that overlaps the cam. The cam consequently engages in the latching contour as soon as the drive disk assumes the predetermined position and, for example, the end position or basic position or neutral position.
- the cam in question and the contour are usually formed onto the drive pulley.
- Such an embodiment is recommended in particular if the drive pulley is made of plastic.
- embodiments made of metal, for example aluminum, steel or brass, are also conceivable.
- the design is often such that both the contour and the cam are usually arranged on an underside of the drive pulley.
- the opposite top of the drive pulley is equipped, for example, with an actuating contour, with the help of which the drive pulley in the example of the opening drive works directly or indirectly on the pawl to open the locking mechanism consisting of rotary latch and pawl.
- the actuating contour for acting on the functional element or the functional unit on the one hand and the contour interacting with the spring as well as the cam on the other hand can be designed independently of one another.
- the contours in question can be particularly easy and Realize inexpensively, namely by being advantageously formed on the drive pulley.
- an electrical current acting on the motor can be detected as a function of the (supporting) force built up by the spring.
- a control unit is generally provided, with the aid of which the electric motor drive is acted upon and which evaluates the electrical current for acting on the motor.
- a sensor that is additionally provided in an electrical supply line of the electric motor can be evaluated with the aid of the control unit for detecting the current intensity drawn by the electric motor.
- the control unit ensures that the electric motor is acted upon directly, so that it can also be used to record the current drawn for the actuation of the electric motor. In this way, practically any position for a possible intermediate stop of the drive pulley can be realized and implemented. This is because, depending on how the drive disk acts on the spring, the spring either provides mechanical support for the rotational movement of the drive disk and consequently reduced current consumption, or it ensures that in the opposite direction and when the spring is tensioned, an increased current consumption is observed to act on the electric motor.
- control unit As soon as a corresponding current value for the current consumption of the electric motor has been detected by the control unit, which corresponds to a desired position of the drive pulley, the control unit ensures, for example, that the electric motor is switched off and the drive pulley consequently assumes and maintains the specified position. A possible after-running of the drive pulley due to mass inertia can also be taken into account.
- the drive pulley can not only be transferred into the basic positions, namely the basic position or basic position and neutral position and the end position or end position, whereby one or both positions can advantageously and additionally be mechanically secured, namely through the interaction between the latching contour in the extension arm of the drive leg and the cam on the drive pulley.
- practically any intermediate position of the drive pulley can be reproducibly approached via the relationship between the current consumed and the angular position of the drive pulley. This is particularly important and advantageous in the event that the electric motor drive is to be used, for example, inside a motor vehicle lock and different functional positions are to be displayed with its help, such as "theft-proof", “child-proof” or “locked” etc.
- the associated actuating contours that are required in each case and are usually designed separately can be brought into engagement with associated levers.
- an electric motor drive for motor vehicle applications is made available which is structurally particularly simple and inexpensive.
- the electric motor drive uses a spring that is tensioned in its basic position in such a way that when a functional element or a functional unit is acted upon, the spring additionally releases its stored spring energy from the basic position and thus supports the drive movement of the drive pulley.
- a correlation between the current consumed by the electric motor and the associated (angular) position of the drive pulley can An intermediate stop can be made and implemented at practically any position on the drive pulley. This is where the main advantages can be seen.
- FIGS 1 and 2 the electric motor drive according to the invention during an opening process
- FIGS. 1 to 4 shows a modified embodiment of the drive according to FIGS. 1 to 4,
- an electric motor drive for motor vehicle applications is shown.
- the electric motor drive is an opening drive for a motor vehicle lock, which is shown and reproduced with its essential components in FIG.
- a locking mechanism 1, 2 of the motor vehicle lock in question can be seen, which is or can be a motor vehicle door lock.
- the locking mechanism 1 , 2 consists of a rotary latch 1 and a pawl 2 .
- a release lever 3 is implemented, with the help of which the pawl 2 can be lifted from its latching engagement with the rotary latch 1 (in the illustrated closed position of the locking mechanism 1, 2).
- the release lever 3 performs a clockwise movement about its axis so that the pawl 2 is lifted counterclockwise from its latching engagement with the rotary latch 1 in the closed position of the locking mechanism 1, 2 shown in FIG.
- the rotary latch 1 opens with the aid of a spring, specifically in a clockwise direction, and releases a previously caught and indicated locking bolt.
- an associated motor vehicle door can be opened.
- the electric motor drive is provided and designed to open the locking mechanism 1, 2 or act on the release lever 3 as a functional element or functional unit.
- the electric motor 4 has an output worm 5 on its output shaft, which interacts with a drive pulley 6 in that the output worm 5 engages in a toothing of the drive worm 6 and this rotates clockwise and counterclockwise about an axis 7 moves, as a double arrow in Fig. 1 makes clear.
- An actuating contour 8 is provided on an upper side of the drive pulley 6 and is designed to pivot the release lever 3 counterclockwise about its axis in order to open the locking mechanism 1 , 2 .
- Flierzu corresponds to a clockwise movement of the drive pulley 6 in the front view or when looking at the top of the drive pulley 6.
- the clockwise opening movement of the drive pulley 6 when looking at the top side of the drive pulley 6 consequently corresponds to the drive pulley 6 making a counterclockwise movement about its axis 7 when looking at the bottom side of the drive pulley 6 .
- the spring 9 is designed in such a way that it transmits a force supporting the drive to the drive pulley 6 .
- the spring 9 is designed as a torsion spring.
- the spring 9 has a coiled section 9a which is connected to a pin 11 in a stationary manner.
- the pin 11 is integrally connected to a motor vehicle lock housing 12 according to the embodiment example and not limiting.
- the leg spring 9 has two legs 9b, 9c.
- Leg 9b is a drive leg 9b, which interacts with contour 10 on drive disk 6 (on its underside), which has already been explained above.
- the other leg 9c is designed as a fixing leg 9c of the leg spring 9 and lies against a stop 13 on.
- the stop 13 like the pin 11, is (in one piece) connected to the lock housing 12 (made of plastic).
- the drive leg 9b of the spring or leg spring 9 ensures the support of the electric motor drive or the support of the drive disk 6 during an opening process.
- This opening process of the drive pulley 6 corresponds to a counterclockwise movement of the drive pulley 6 in relation to the axis 7 and in the view from below or the view of the underside of the drive pulley 6, as can be understood from a sequence of Figures 1 and 2.
- the drive leg 9b of the spring or leg spring 9 rests against the contour 10 of the drive disk 6 and during the opening process increasingly spreads open in relation to the stationary fixing leg 9c.
- the tension of the spring 9 expresses itself in a relatively small angle a between the drive leg 9b and the fixing leg 9c, which is approximately 40 to 50° according to the exemplary embodiment.
- the drive arm 9b now spreads open in relation to the fixing arm 9c until approximately the end position E or end position of the drive disk 6 shown in FIGS. 2 and 3 is present and observed.
- Both legs 9b, 9c then enclose an angle ⁇ of approximately 110° to 120°. Since the spring or torsion spring 9 relaxes in this way, the spring energy or clamping energy that is released in this way can be used to support the movement of the drive disk 6 and thus of the entire drive.
- the drive leg 9b moves against a further stop 14.
- This is like the stop 13 and the pin 11 usually connected in one piece to the lock housing 12 .
- the stop 14 is made of plastic.
- the spring 9 or torsion spring is increasingly tensioned because the drive leg 9b is increasingly moved towards the fixing leg 9c in contact with the contour 10 and the spring 9 is thus equipped with the required tensioning energy.
- FIG. 5 now shows a variant in which the drive leg 9b is equipped with an extension arm 9b'.
- the extension arm 9b' has a latching contour 15 which is designed as a bulge or recess in the extension arm 9b' in question.
- a cam 16 is provided and implemented on the underside of the drive disk 6, which engages in the latching contour 15 as soon as the drive disk 6 assumes a corresponding position.
- the described interaction between the latching contour 15 and the cam 16 can also be present in any other desired position of the drive disk 6 and can be implemented.
- the procedure is such that first of all a control unit 17 is provided, with the aid of which the electric motor 4 and thus the entire electromotive drive is controlled and acted upon.
- the control unit 17 can now detect an electric current acting on the electric motor 4 .
- the power consumption at the electric motor 4 can be measured directly or recorded using a sensor, not shown. This from The electric current taken up by the electric motor 4 and applied to it is now dependent on the force built up by the spring 9 .
- FIG. 7 A corresponding and schematic relationship is shown in FIG. 7.
- the current consumed by the electric motor 4 is shown in relation to the travel path covered by the drive pulley 6, which is manifested in an associated pivoting angle of the drive pulley 6 about its axis 7.
- the swivel angle or angle in question is shown and reproduced between the basic position G and the end position or end position E of the drive pulley 6 .
- the current consumed by the electric motor 4 increases in the direction of the basic position or basic position G because the spring 9 is tensioned in the direction of the basic position G.
- the power consumption decreases in the direction of the end position or end position E, because in this direction the spring 9 supports the movement of the drive disk 6 and thus of the entire electric motor drive.
- each value for the current consumption of the electric motor 4 can be identified with a corresponding angular position of the drive pulley 6 between the basic position G and the end position E.
- the drive pulley 6 can be moved into practically any angular position between the basic position G and the end position E, namely in that the current drawn by the electric motor 4 is detected via the control unit 17 and the charging of the electric motor 4 is stopped when the desired angular position is reached.
- any after-running of the electric motor drive caused by the mass inertia can of course also be taken into account.
- This overrun may result in an additional traverse path or an additionally swept angle of the drive disk 6 during its rotational movement about the axis 7 and can also be taken into account by the control unit 17 in such a way that the electric motor 4 is stopped before the desired angular position is reached, namely reduced by an angular amount corresponding to the overrun. If, for example, the angular position of 20° of the drive pulley 6 is to be approached with a lag of 5°, the control unit 17 ensures that the electric motor 4 is switched off when the angular position of 15° is reached.
- this allows the electromotive drive or its rotatable drive disk 6 to be moved to a desired position.
- This is essential for controlling different functional positions within the motor vehicle lock in the example, for example in order to be able to represent and implement functional positions such as “theft-proof”, “child-proof” or “locked” with the help of the electric motor drive.
