Definitions

  • the invention relates to a positioning device for a motor vehicle door element comprising an electric drive and an adjusting means, wherein the adjusting means is adjustable by means of the drive and a gear arranged between the adjusting means and the drive, so that a movement of the door element is possible, and a mechanical brake for braking the door element.
  • Today's motor vehicles are increasingly being equipped with comfort functions. For example, to make it easier to get into a motor vehicle, to move a door independently and/or to be able to influence the aesthetic and aerodynamic design, motor vehicles are equipped without an external door handle. However, it is also conceivable that an external door handle is provided, but this is only used to operate a switching device, for example to control an electrically operated lock and/or a setting device for a side door. So-called setting devices or door openers are used to make it easier to get in and out of a motor vehicle.
  • An automatic closing mechanism for a side door of a two-lane passenger car has become known. If a door is closed manually, for example, the side door goes into a first pre-locking position in which the door is secured but not completely closed.
  • a sensor device such as a switching element, can query the position of the locking mechanism in the vehicle lock and provide a signal with which an automatic closing mechanism can be controlled.
  • the automatic closing mechanism which is also called a closing aid, the locking system then moves from the pre-locking position to a main locking position.
  • a braking device for a door actuator is known from the US20170260790 A1 known.
  • a door stay is usually pivotally attached to the A-pillar of a motor vehicle, for example, and is also slidably mounted in the motor vehicle door.
  • the publication mentioned discloses a braking system for continuously braking the moving door, whereby two brake shoes can be moved against each other by means of an electric drive and a spindle gear, whereby the brake shoes enclose the door stay and thus enable continuously braking of a moving door.
  • a positioning device for a motor vehicle door element comprising an electric drive and an adjusting means, wherein the adjusting means can be adjusted by means of the drive and a gear arranged between the adjusting means and the drive.
  • the drive kinematics make it possible to move a door element, wherein at the same time a mechanical brake for braking the drive movement of the electric drive is disclosed.
  • the EP 3 299 561 A1 , EN 10 2009 006948 and EN 10 2016 211777 reveal further examples of mounting devices with a brake.
  • the object of the invention is to provide an improved positioning device for a motor vehicle door element.
  • the object of the invention is to provide a positioning device that enables safe braking and also enables the door element to be operated independently of the drive.
  • the object of the invention is to provide a structurally simple and cost-effective solution.
  • the object of the invention is achieved in that a positioning device for a motor vehicle door element is provided, having an electric drive and an actuating means, wherein the actuating means can be adjusted by means of the drive and a gear arranged between the actuating means and the drive, so that movement of the door element is possible, and a brake for braking the door element, wherein the brake interacts with an output shaft of a drive motor.
  • the structure of the positioning device according to the invention now creates the possibility of enabling safe braking of the positioning device, wherein the interaction of the brake and output shaft enables braking to take place directly in the area of the drive.
  • the structure according to the invention makes the brake independent of the actuating means, the gear and/or a possible door movement. The brake thus enables intervention in the electric drive train in the area of the drive motor.
  • the positioning device is used for a motor vehicle door element.
  • the motor vehicle door element can also be a flap, hood or a cover, for example for a convertible roof.
  • the positioning device can move, brake or hold the door element that is movably arranged on the motor vehicle.
  • the positioning device advantageously works together with an electrically operated locking system, so that a high degree of design freedom is possible when designing the door element.
  • the door element can dispense with a door handle, which results in almost any shape on the outside of the door element.
  • the positioning device is usually arranged in the area of the door element in such a way that By actuating the positioning device, the door element can be positioned, i.e. it can be moved from a closed position to an open position.
  • the positioning device generates a relative movement between the body and the door element, whereby the positioning device is preferably arranged in the door element itself.
  • An arrangement in the body for moving the door element is of course also conceivable.
  • the electric drive preferably consists of a direct current motor that interacts with an output shaft and, for example, via a worm gear and/or another gear stage with the actuating means.
  • Single, two or multi-stage gears are conceivable, whereby the choice of gear can influence the force available on the actuating means.
  • the actuating device is arranged in the door element in such a way that the actuating device interacts with an A-pillar of the motor vehicle and a front door, higher forces are required to set up the door element than if the actuating device is used for a wing door, i.e. a door that is not arranged on the motor vehicle so that it can be pivoted on its own.
  • the electric drive enables the actuating means to move.
  • the electric motor makes it possible to move the actuating means in such a way that the door can be opened by the driven actuating means.
  • the actuating means moves relative to the body and exerts a pressure force on the vehicle door element so that the unlocked and unlocked door can be moved.
  • the installation device preferably works together with a motor vehicle lock which has a rotary latch and at least one pawl, whereby the locking mechanism consisting of the rotary latch and at least one pawl can be unlocked electrically.
  • a motor vehicle lock which has a rotary latch and at least one pawl, whereby the locking mechanism consisting of the rotary latch and at least one pawl can be unlocked electrically.
  • the operator of the motor vehicle only needs an electrical impulse to move the locking system into an unlocked, i.e. open, position.
  • the locking system is then open, so that the door or flap is movable.
  • the electrical opening pulse for the vehicle lock can be generated by means of a sensor, a key or, for example, by means of a sensitive device such as a touch sensor or an outside door handle with an integrated sensor.
  • the door element can be pivoted on the hinges. Once unlocked, the door can then be moved using the setting device, whereby the movement of the vehicle door element can be detected using a sensor, for example an incremental encoder. The entire setting process is recorded. Continuous detection takes place so that the door position can be determined at any time during the movement of the vehicle door element using the setting device. Once a door has been manually moved beyond the movement of the setting device, it can be intercepted using an overload clutch, for example.
  • the driving force or torque introduced into the actuating means by means of the electric drive can be braked by means of the brake.
  • the design of the positioning device according to the invention thus makes it possible to prevent or stop the door movement, so that, for example, if an obstacle is detected, the door movement can be braked.
  • the positioning device also serves to prevent movement of the door due to the effect of gravity, as can occur, for example, when the vehicle is parked on a slope, or due to the effect of wind force. Movement of the door element due to manual force can also be prevented by means of the brake up to a definable breakaway force.
  • the brake works indirectly with the output shaft by means of a retaining disk.
  • the brake can, for example, act on a radially outer radius of the retaining disc and thus increase the braking effect on the output shaft.
  • the retaining disc can, for example, be pushed as a circular disc onto an output shaft with a D-shaped cross-section.
  • a positive connection between the retaining disc and the motor shaft offers the advantage of securely transmitting torque.
  • other shapes such as a propeller shape, are of course also conceivable as a positive connection between the retaining disc and the output shaft.
  • the output shaft is accommodated in the mounting device by means of a bearing, in particular a roller bearing, this results in a further advantageous embodiment of the invention.
  • the output shaft is additionally supported in the mounting device by the bearing, which can in particular be a roller bearing and for example a ball bearing or deep groove ball bearing or a plain bearing, so that on the one hand a safe introduction of the drive torque into the downstream transmission is possible and on the other hand a counter bearing for the brake can be provided.
  • the bearing By arranging the bearing in the immediate vicinity of the retaining disk, a high braking torque can also be introduced into the output shaft at the same time without affecting the engagement conditions in relation to the downstream transmission.
  • the type of bearing is not limited here, but preferably results from the structurally specified installation space, the forces and moments present in the mounting device and the necessary service life of the mounting device.
  • the brake has a brake lever, whereby the brake lever can be brought into engagement with the retaining disc.
  • the brake lever provides a possibility for braking, in order to suitable mounting points for the lever and an alignment with the output shaft or the retaining disc can influence the braking effect and the torque introduced into the output shaft.
  • the brake can therefore be adapted to the requirements of the installation device. Adaptation to the braking torque may be necessary, for example, due to the size of the door element to be moved, if, for example, high doors, such as those found on vans, can be positioned or moved using the installation device.
  • the brake lever can be operated manually and/or electrically.
  • the brake lever can, for example, be operated manually using a door handle.
  • the door handle can be connected directly to the brake lever via a Bowden cable and/or connected to the brake lever via a rod.
  • an inside door handle and/or an outside door handle can be brought into engagement with the brake lever in order to operate the brake. This makes it possible to prevent the drive process and position the door in the desired position.
  • a control unit that works together with an incremental encoder of the positioning device for example, can detect this braking and, for example, switch off the electric drive.
  • the setting device can have another motor, in particular a DC motor, which interacts with the brake lever.
  • a switching signal for actuating the electric drive to actuate the brake lever can then be sent, for example, by means of a radio remote control, a vehicle key or a door handle.
  • the brake counteracts the drive of the setting device and can cooperate with the drive of the brake lever, in particular in the case of electrical operation of the brake lever. Electrical operation of the brake lever then leads directly to switching off of the electric drive of the installation device, so that only the door movement needs to be slowed down using the brake or the brake lever.
  • the brake can also be used as an emergency safety device if, for example, a door movement is to be prevented using a sensor or manual intervention, and can therefore be used to secure the position of the door element.
  • the brake counteracts the door drive and brakes the electric drive of the installation device.
  • the switchable brake is designed in such a way that the drive motor of the installation device can drive the device even when the brake is closed. The door is blocked from moving manually. This enables the motor to start up even without the brake being actively released.
  • a further embodiment of the invention arises when the brake lever can be driven by means of a gear, in particular an actuating contour of a gear, and an electric motor. If the drive motor for the brake acts on a gear, a transmission can be provided to drive the brake lever.
  • a worm gear stage can be used here in an advantageous manner.
  • the gear driven by the worm has an actuating contour that is preferably formed integrally with the gear. It is also conceivable to design the gear as just a gear segment, for example for reasons of weight or space.
  • the actuating contour engages with an engagement surface of the brake lever and thus actuates the brake lever, which is preferably pivotably mounted in the mounting device. Depending on the design of the actuating contour, a continuous increase in the introduction of a force into the brake lever or a very rapid movement of the brake lever can be set.
  • the brake lever is bistable, in particular by means of a spring element, mounted in the mounting device, this results in a further embodiment of the invention.
  • the brake electrically into an open or braking state and remains in this position. This means that the brake lever is held in its starting position or in the engaged position.
  • the bistable spring thus secures the position of the brake lever and preferably also holds the brake lever in the functional positions. In the starting position of the brake lever, the spring then simultaneously serves as a position lock and can hold the brake lever against a stop buffer in the mounting device.
  • the spring element can eliminate noise that would be caused by, for example, a vibration-related movement of the brake lever.
  • the bistable position of the brake lever in the braking position makes it possible to design the gear without self-locking, whereby the brake can serve as a positioning means for the gear and thus the actuating means.
  • a design of the gear without self-locking also offers the advantage that the door can be grasped manually, for example, and moved against a movement of the positioning device. This can be advantageous not only when grasping manually, but also, for example, when the moving door element hits an obstacle. If an obstacle is encountered, the door drive is switched off and the door can be moved back manually, for example.
  • the brake lever can be operated manually using an inside door handle, this results in a further variant of the invention.
  • the brake can be mechanically connected to an inside door handle, so that the brake can be released, for example, by an excessive stroke of the inside door handle.
  • a switching device can be present on the inside door handle, so that when the inside door handle is operated for the first time, the electric lock is opened, i.e. unlocked, and the positioning device can operate the door element. If this door movement is to be prevented or interrupted, then, for example, by pulling the inside door handle again, the brake can be released. the brake can be activated or operated. This provides an easy and intuitive means of operating the brake.
  • the brake lever has a braking element, in particular a rubber-elastic braking element.
  • the brake lever has a rubber-elastic braking element that can be brought into engagement with the output shaft of the drive motor and/or the retaining disk.
  • the braking effect of the brake can be increased by a rubber-elastic braking element and at the same time the braking effect can be controlled. Controllable in the sense that the braking effect can be continuously increased by moving the brake lever in the direction of the retaining disk, for example.
  • the rubber-elastic braking element can serve as a stop buffer, so that the electric drive can be braked quietly.
  • the rubber-elastic braking element can be formed in one piece with the brake lever or, for example, connected to the brake lever in a form-fitting manner.
  • the braking element has a width that is at least the same as the retaining disk, so that the braking element can be in full contact with the retaining disk.
  • the design of the brake element as a rubber-elastic brake element is of course only one advantageous design variant; other brake elements can of course also be used which have a favorable, i.e. a high, friction coefficient in relation to the holding element or the output shaft.
  • the brake element is arranged between a bearing point of the brake lever and an engagement surface of the actuating contour of the gear.
  • the brake lever is pivotally mounted in the housing of the setting device.
  • the bearing point of the brake lever is preferably arranged in the housing near an axial end of the output shaft.
  • the brake element is connected to the bearing point of the brake lever, the brake element being arranged in the area of the retaining disk.
  • the brake lever preferably along the axial extension of the output shaft of the drive motor of the installation device.
  • the brake lever has an engagement surface for manual and/or electrical actuation.
  • the brake lever is preferably electrically actuated so that the engagement surface can be brought into engagement with an actuating contour of a gear.
  • Such an advantageous design allows the braking torque on the holding disk to be adjusted and results in favorable lever ratios in order to be able to introduce a high braking torque into the holding disk and thus the output shaft of the motor. This means that the output shaft can be safely braked, with braking being possible independently of any intervention in the door element. Braking takes place directly in the area of the electrical drive of the installation device. In addition to simply holding the door element, for example on a slope or in strong winds, the braking element can also serve a dual function to brake the door movement.

  • the gear segment 9 meshes with a first in the Figure 1 not visible pinion, the pinion being connected to an intermediate gear 11 for transmitting a torque.
  • an overload clutch 12 is arranged between the pinion and the intermediate gear 11, so that a limitation of the torque that can be transmitted by means of the gear 10 is possible.
