Definitions
- DE 10 2015 115 673 A1 discloses a flush outside door handle, wherein the outside door handle can be moved out of the door surface by means of a corresponding mechanism.
- the door handle can be moved back and forth to two different positions. Starting from a flush first position, the door handle can be opened using a mechanism can be moved to a second position in which the outside door handle protrudes from the door surface. In this second position, the outside door handle can be grasped by the operator and the door can be opened.
- an extensive mechanism is disclosed, which moves the outside door handle in an electrically driven manner.
- the generic state of the art is formed by DE 10 216 113 167 Al.
- the publication discloses a device for driving a door handle of a motor vehicle for moving the door handle from a first position, in particular a rest position, into a second position, in particular an actuation position, comprising an electric drive, a transmission connected downstream of the electric drive and an output gear associated with the transmission , whereby a movement in the door handle can be initiated by means of the driven gear.
- the first position of the door handle is the position, which can also be referred to as the starting position, in which the door handle is flush with the outer skin of the body and preferably the side door.
- the second position refers to a position of the door handle after the door handle has completed a translational movement and protrudes from the body of the motor vehicle. In this extended position, the operator is able to operate the door handle and unlock a motor vehicle lock.
- the translational movement is carried out by means of an output gear and in interaction with a rack arranged on the door handle.
- the door handle drives known from the prior art are in need of improvement overall.
- the state of the art has complex mechanics, which again seems to be prone to failure and particularly susceptible to external weather influences and, on the other hand, safe operation cannot be guaranteed using a simple electric drive with a motor and gear, especially in the event of a power failure.
- the door handle In particular in the event of a power failure, the door handle must be moved back to its original position, whereby the door handle must be moved out of the power-free position.
- the disadvantage here is that the position of the door handle cannot be clearly determined and the mechanics are heavily stressed if it hits a stop. This is where the invention comes in.
- the object of the invention is to provide an improved device for driving a door handle of a motor vehicle, which overcomes the disadvantages of the prior art.
- a device for driving is preferred indirect drive
- a door handle f fs of a motor vehicle for moving the door handle f fs from a first position, in particular a rest position, into a second position, in particular an actuation position comprising an electric drive, a gearbox connected downstream of the electric drive and a Gearbox associated output gear, a movement in the door handle can be initiated by means of the output gear and at least one gear part is assigned a means for position detection.
- the control can be designed in such a way that the door handle can not only be moved quickly, but the door handle can also be braked gently when the end positions are reached.
- a door handle of a motor vehicle this includes all handles that can be moved by means of a drive.
- This is not limited to a door handle, but can also include tailgates, covers, sliding doors or flaps, wherever they are arranged to be pivotable or movable on the motor vehicle Components are arranged that are equipped with a retractable door handle.
- the drive does not have to directly drive the door handle, but there is also the possibility that the drive acts on a lever chain, with the lever chain then actuating the door handle or opening and closing it.
- the door handle In a first position, the door handle assumes a position in which the door handle is preferably flush, that is to say flush with the body. This makes it possible to achieve an optimal aerodynamic surface on the motor vehicle and at the same time the door handle does not disturb the appearance of the motor vehicle. Rather, in the flush position, the door handle can be represented as a unit with the motor vehicle surface, so that one can also speak of a disappearing technology.
- the door handle is only moved out of the flush position when the operator wants to open the motor vehicle.
- the device for driving moves the door handle into an extended second position, which can also be referred to as the operating position.
- the door handle protrudes at least partially from the surface or from the surface in such a way that the operator can grasp and operate the door handle.
- the movement of the door handle is not limited to a linear movement, but can also consist of a pivoting movement or a combined movement of a linear, rotary or pivoting movement.
- the door handle can be made available to the operator in the operating position.
- the electric drive used is preferably an electric motor and in particular a DC electric motor.
- a gearbox is connected downstream of the electric drive, whereby the gearbox is not limited to one gear stage but can include two, three or more gear stages. Depending on the desired force that should be available to the door handle in order to move the door handle or to generate the fastest possible movement of the door handle, a different gear ratio can be advantageous.
- an output gear of the transmission moves the door handle or initiates the movement into the door handle.
- the means for position detection is at least partially integrated into a transmission part.
- the position detection means can be, for example, a microswitch that interacts with a contour of a transmission component. If more than one microswitch is installed, the microswitch can be used to detect different positions for controlling the movement of the door handle and thus ensure controlled movement of the door handle.
- a means for position detection be integrated into at least one transmission part.
- Examples include a door module carrier, a window guide, a motor vehicle lock, a closing aid, etc. Due to the large number of components, the space required inside the door is limited. If, according to the invention, the means for position detection is integrated into a transmission component is integrated, the device can be designed to be smaller overall.
- the means for position detection is a magnet, the magnet interacting with a sensor, in particular a Hall sensor.
- the use of a magnet is possible in the simplest manner, in particular the integration of a magnet into a transmission component can be realized using the simplest design means.
- the gear components are mostly made of plastic, although a drive pinion, for example a worm wheel, on the drive shaft of the electric motor can alternatively also be made of a metallic material.
- the other transmission components are preferably made of a plastic. This makes it possible to place the magnet in a gear of the transmission in the simplest way possible. For example, a recess can be made in a transmission component into which the magnet can be inserted.
- the means for attaching the magnet can be a positive connection, a force connection or a material connection.
- a magnet it is of course also conceivable to integrate two or more magnets in one or more gear components in order to obtain further data about the gear position.
- the magnet is a diametrically magnetized magnet
- An even more precise position detection of the transmission can be determined using a diametrically split magnetized magnet, since the diametrically split magnetized magnet allows at least two position values to be determined using a sensor. can be recorded using. This means that twice the number of signal values is available for position detection, even though only one magnet is used.
- the invention is not limited to a diametrically magnetized magnet; it is also conceivable that, for example, an axially arcuately magnetized magnet is used. What is essential to the invention is that the polarity on the magnet enables the movement of the gear components to be detected. For example, the movement can be detected using a Hall sensor.
- the magnet is integrated into the output gear of the transmission.
- the output gear engages directly with the operation of the door handle, and an output shaft present on the output gear can be provided with teeth that are directly assigned to the operation of the door handle.
- the door handle can be moved by means of the output gear as the last transmission component and can be moved from the first position to the second position and vice versa.
- the driven gear interacts directly with the door handle or is connected to the door handle via a mechanism, a more precise value for the movement of the door handle can be recorded on the driven gear.
- the driven gear therefore forms an advantageous position in the transmission in order to safely detect the movement of the door handle.
- the driven gear can, for example, have a recess into which a cylindrical magnet can be inserted.
- the magnet by integrating the magnet into the output gear, a space-saving arrangement of the magnet can be achieved and the cylindrical, i.e. symmetrical, structure of the magnet can also provide a structural tively simpler because of the symmetrical design of the output gear.
- the magnet interacts with a circuit board assigned to the device.
- the printed circuit board can be arranged in a housing of the device or can be connected to the housing of the device.
- a sensor means in particular at least one Hall sensor, which interacts with the magnet, is arranged on the circuit board.
- the circuit board is arranged in relation to the transmission in such a way that the movement of the magnet can be detected.
- the device for driving the door handle is arranged in a separate housing.
- Arranging the device in a separate housing provides a modular component for driving the door handle.
- the device module can be available for different handles in different vehicles, since the device provides a means for driving the door handle and for detecting the position of the door handle.
- the device housing is designed in such a way that at least the circuit board can be mounted in the housing or on the housing, whereby it is also conceivable that the housing has an Has extension into which the circuit board is inserted for position detection and/or control.
- the device housing is sealed, in particular closed by means of a laser.
- the device housing is preferably used inside the door and preferably in the area of the door handle.
- the area of the door handle is exposed to environmental influences, since the side windows of the motor vehicle are used in a sealing manner, but cannot completely seal off the interior of the door element. There is therefore the possibility that, for example, rain or water penetrates into the door when the motor vehicle is being cleaned and can reach the area of the device to drive the door handle. It is therefore important that the device is designed to be protected from moisture.
- the motor and the gearbox are located in the device housing, which is designed, for example, as a shell.
- the cover can be screwed in order to achieve a sealing device housing.
- the cover can be screwed in order to achieve a sealing device housing.
- the operating speed of the door handle and the available force i.e. the working torque of the device
- This makes it possible to generate moments that achieve a blocking moment of greater than 2 Nm at the stop, i.e. in, for example, a second position of the door handle, i.e. the actuation position.
- the speed and the force or torque on the door handle can be adjusted by adjusting the gear ratio.
- the output gear is assigned an output shaft, the output shaft advantageously being designed in one piece with the output gear. Due to the one-piece design of the output gear and output shaft, a safe output torque can be transmitted and a device for driving the door handle can be provided with the smallest possible number of components. If the magnet is also integrated into the output gear, the output gear has a number of functions. On the one hand, the output gear is used for position detection and, on the other hand, the output gear provides an output torque for moving the door handle.
- the one-piece structure offers an advantageous and structurally favorable option for operating the door handle.
- FIG. 1 shows a three-dimensional view of a device for driving a door handle of a motor vehicle with a closed housing and an output shaft protruding from the housing
- FIG. 2 shows a top view of the device according to FIG. 1 from the perspective of the arrow II from FIG. 1 without the housing cover
- Figure 3 shows a detailed view of the device without the output pinion and the output shaft, whereby the position of the magnet in the device can be seen, and
- Figure 4 shows the output gear with integrated magnet and integrally formed output shaft.
- FIG. 1 shows a three-dimensional view of a device 1 for driving a door handle of a motor vehicle.
- the device 1 can be attached to a door module carrier in the area of a door handle using screw openings 2, 3, for example.
- 4 extensions 5, 6 are integrally formed on the housing, ensuring a secure hold can be guaranteed for the device 1.
- a further receptacle 7 is also formed on the housing 4 in the form of a downwardly open housing recess, into which, for example, a circuit board 8, which is only indicated, can be inserted.
- the receptacle 7 can be closed with a housing cover, not shown, whereby the housing cover can snap into a clip connection 9.
- the device 1 is closed with a housing cover 10.
- An output shaft 11 protrudes from the housing cover 10, the output shaft 11 being used to move the door handle. To do this, the output shaft can be driven back and forth in the direction of arrow PI.
- the housing cover 10 is welded all around to the housing 4 using a laser seam.
- the housing cover 10 in turn has bearing points for the transmission components, as well as a positive receptacle 15 for the electric drive 16.
- a plug socket 17 for electrically contacting the device 1 can also be seen in FIG.
- the output gear 23 is actuated via the worm gear stages 19, 20 and the gears 21, 22.
- the drive means in the form of the output shaft 25 connected to the output gear can then be used to move the door handle.
- a sealing ring is provided on the output shaft 25, which, in conjunction with the housing cover 10, seals the transmission 24 and the electric motor 18.
- a magnet 30 can be seen, which is arranged as an integral part of the output gear 23 in the device 1 and in the transmission 24.
- the magnet is diametrically divided along a center line M and has two magnetic poles 31, 32.
- the magnet 30 also has notches 33, 34, so that a positive connection can be produced between the driven gear 23 and the magnet 30. This means that there is a positive connection between electromagnetic net 30 and output gear 23 can be produced, so that the magnet 30 can immediately follow the movement of the output gear 23.
- FIG. 4 shows the output gear 23 with the connected output shaft 25, whereby the magnet 30 integrated into the output gear 23 can be seen at the same time.
- An extension 35 on the output gear 30 serves as a bearing point for the output gear 23.
- the bearing point 35 is accommodated in the housing 4 in this exemplary embodiment.
- an increase on the output gear 23 interacts with the notch 33, so that a tongue and groove connection can be formed between the magnet 30 and the output gear 23.
- the door handle Due to the interaction between magnet 30 and output gear 23, the door handle can be positioned precisely and the position of the output gear 23, the output shaft 25 and thus the door handle can be determined by means of a Hall sensor arranged, for example, on the circuit board 8. This means that the door handle can be moved safely and the door handle can be moved very precisely so that the mechanical system is subjected to the least possible stress.
