Definitions

  • the invention relates to an opening device for a motor vehicle door element, in particular a side door, having an electric drive, an actuating means and a spring accumulator arranged between the drive and the actuating means.
  • Today's motor vehicles are being provided more and more with comfort functions. For example, in order to make it easier to get into a motor vehicle and to be able to influence the aesthetic and aerodynamic shape, motor vehicles are equipped without an external door handle, for example. However, it is also conceivable that an outside door handle is provided, but this only forwards a switching signal to the motor vehicle door lock for opening. In order to make boarding easier, to automate it and to make it possible, for example, in vehicles without outside door handles, so-called open positioning devices or door openers or door openers are used.
  • An opening device for a motor vehicle door is known, for example, from DE 198 35 994 A1.
  • the positioning device is equipped with a spindle drive.
  • the spindle drive or the ejector device is activated by unlocking an associated door lock on a flap and in particular a tailgate.
  • the flap is pivoted with the aid of the ejector device and a gap is formed, to which a first opening position is assigned.
  • an opening device for a motor vehicle door has become known, in which an opening of the door element is possible by means of an electric drive and an actuating means.
  • a spring accumulator is arranged between the electric drive and the actuating means, it being possible for an additional opening force to be introduced into the opening movement by means of the spring accumulator.
  • the spring accumulator is designed in such a way that during a pulling movement initiated by the electric drive onto an actuating rod, the spring accumulator serves as a transmission means.
  • the spring accumulator can thus have a dampening effect on the pulling process and is also able to generate an increased pulling force.
  • the solutions known from the prior art for setting up a door element have basically proven their worth, but they reach their limits when the door element needs to be set up quickly.
  • the actuating devices are based on electric drives, by means of which the door element is transferred from a closed position to an open position. It can be problematic that the positioning times of the motors, which are usually still provided with gears, cannot correspond to the required positioning times for opening the door element.
  • the task is to provide an improved opening device for a motor vehicle door element.
  • the task is to provide an adjustment device that can convince with short adjustment times and beyond constructively simple means and thus allows inexpensive installation of the door element.
  • the object of the invention is achieved in that an opening device for a motor vehicle door element, in particular a side door, is provided, having an electric drive, an actuating means and a spring accumulator arranged between the drive and the actuating means, it being possible to open the door element by relaxing the spring accumulator is.
  • the construction of the positioning device according to the invention provides a simple structural means for setting up a door element. The force available for opening the door element can be adjusted by selecting the spring element. The spring accumulator can be tensioned by means of the electric drive.
  • the electric drive can tension the spring accumulator so that the spring accumulator is tensioned in the non-actuated state of the actuating means, ie when the door element is closed the actuating element is in the retracted state and in tensioned form. If, on the other hand, the door element is opened or a door lock receives a signal to unlock the door lock, the spring accumulator is released and moves the door element into an open position.
  • the lifting movement that Control element performs can be limited by the structural design of the spring element.
  • the door panel is set up over a distance of 50-100mm and more preferably over a distance of about 60-80mm.
  • the positioning device is tied to an electrically operated door lock.
  • An electrically operated door lock is characterized in that a locking mechanism integrated in the door lock can be unlocked electrically.
  • the locking mechanism preferably has a rotary latch and a pawl, but two or more pawls and/or blocking levers and/or locking levers can also hold the rotary latch in the closed position.
  • the locking mechanism has a rotary latch and a pawl, with the locking mechanism having a closing moment in a main latching position.
  • the locking mechanism can be unlocked electrically in an electrically operated door lock, so that the door element is released and can be pivoted freely.
  • free pivoting also means that a door catch can also be present on the door element if the door element is a pivoting side door.
  • Electrical unlocking of the locking mechanism is followed by a command or signal that activates the electric drive and releases the spring storage mechanism. The door element can thus be moved into an open position by the opening device.
  • the adjusting means is preferably arranged in the door element, but it can also be in the bodywork, the means to be arranged opposite the door element in the motor vehicle.
  • the adjusting means is preferably flush in an opening of the door element, so that there can be no hindrance for an operator of the motor vehicle if the adjusting means is in the retracted state.
  • the actuating means itself is moved out of the opening when the opening device is actuated and can be brought into engagement with the bodywork or the door element in order to move the door element into the open position.
  • the adjusting element is preferably formed from a metallic material, but can also be formed as a plastic component or hybrid component.
  • the adjusting element is preferably made of a steel material, with at least one damping means, such as an elastic plastic, being able to be arranged in the region of engagement with the body or the door element.
  • the spring accumulator is arranged between the drive and the actuating means.
  • the electric drive is able to tension the spring accumulator.
  • the spring accumulator In the non-actuated state of the positioning device, the spring accumulator is then in a tensioned state. Only when the opening device is actuated is the spring accumulator released and can thus move the door element.
  • the spring accumulator can be tensioned by means of the electric drive.
  • the electric drive moves in such a way that a spring element contained in the spring accumulator is tensioned and is held in the tensioned position by means of the electric drive. Only with the signal to open the door element does the electric drive release the spring accumulator and thus the spring element, so that by means of the spring accumulator or the Spring element in the spring accumulator setting up the door element is possible.
  • a relaxation of the spring accumulator can be controlled by means of the electric drive
  • the electric drive tensions the spring element in the spring accumulator directly or indirectly. If the structural design is then selected in such a way that the setting movement of the spring accumulator can be controlled by means of the electric drive, a defined opening and in particular a defined opening setting movement of the door element can be controlled.
  • This has the advantage that the door can be opened quickly by the spring element, while the electric drive for tensioning the spring element may require a longer time. When released, the electric drive therefore works with the power of the spring accumulator, which enables the door element to be opened very quickly. This is advantageous for the operator, since the door element can be presented quickly immediately after unlocking the door lock.
  • the actuating means can have a longer actuating time.
  • the electric drive can advantageously have a spindle drive.
  • Spindle drives are able to provide high forces to enable corresponding opening forces in the door element. Particularly in extreme situations, in which the door element has to work against the force of icing on a door seal, for example, high actuating forces must be made available in the actuating means.
  • means of the spindle drive on the one hand high forces can be generated and on the other hand it is possible to transfer fast positioning times via the motor speed via the spindle drive.
  • a spindle can be arranged on a drive shaft of an electric motor, with a spindle nut being able to be guided over the spindle. The spindle nut can then directly or indirectly engage with the adjusting means.
  • a further embodiment variant of the invention results.
  • the integration of a Bowden cable makes it possible to arrange the electric drive at a distance from the actuating means in the motor vehicle. This results in a number of design advantages, such as the fact that the actuating means itself can be integrated into the motor vehicle lock, for example, so that a separate housing for the actuating means does not have to be made available.
  • the actuating means can be conveniently arranged in the door element or in the body without requiring space for the electric drive in the area of the actuating means.
  • the Bowden cable can act directly on the spring accumulator so that the actuating means can be guided directly through the spring accumulator, or alternatively there is the possibility of connecting the electric drive to the actuating means so that the spring accumulator can be tensioned by means of the actuating means.
  • the electric drive and, for example, a spindle drive then moves the core of the Bowden cable, the Bowden cable and in particular the core being connected to the actuating means, for example.
  • the spring accumulator can then be tensioned via the actuating means and transferred to its initial position.
  • a further embodiment variant of the invention is achieved when a freewheel is arranged between the drive and the spring accumulator or the actuating means.
  • Freewheeling makes it possible to move the actuating means or the spring accumulator independently of the electric drive.
  • the freewheel can also be formed by the Bowden cable or the Bowden cable connection. There is thus the possibility of moving the actuating means against the direction of movement, which is controlled by the spring accumulator and the electric drive. If, for example, the operator has given the signal to open the door and thus set it up, and the operator immediately decides to interrupt the opening process and close the door element again, then the door element can be closed again, for example by manual intervention, whereby the manual intervention moves the door element back into the closed position. However, the actuating means is then also moved back into the initial position by the manual intervention.
  • the operator has to act against the force of the spring accumulator on the door element, but the freewheel enables the actuating means to be moved back into the starting position before the electric drive moves the actuating means back into the starting position electrically, i.e. motor-driven Has.
  • the compression spring forms a preferred embodiment of the invention.
  • Compression springs are available in many designs and are easy to integrate as a constructive means into the positioning device.
  • a guide needs to be provided, which can be provided, for example, by a door lock or a housing of the installation device.
  • a compression spring can be tensioned indirectly by means of the electric drive and, for example, via a lever mechanism, or directly via a connection, for example, to the Bowden cable. In a particularly advantageous manner, the compression spring can be integrated into the actuating means.
  • the adjusting means can thus have a multiple function.
  • the adjusting means can serve as a guide for the compression spring
  • the adjusting means serves to open the door element and, in addition, the adjusting means can assume the function of tensioning.
  • the adjusting means takes on the compression spring and guides the compression spring, while at the same time, for example, a Bowden cable can act on the adjusting means and controls the tensioning or relaxation.
  • the positioning device is connected to a motor vehicle lock or integrated into a motor vehicle lock, this results in an advantageous embodiment variant of the invention.
  • the connection or integration of the opening device or at least parts of the opening device on or in the motor vehicle lock enables a compact design of several functions in the door element.
  • the actuating means does not require a separate housing.
  • a connection to the motor vehicle lock can offer the advantage that the actuating means on the motor vehicle lock is at least richly supported and can thus be stabilized and guided by the motor vehicle lock.
  • the construction of the positioning device according to the invention makes it possible to provide an inexpensive positioning device that is also equipped with a high level of functionality.
  • quick opening times for the door element can be provided, which can be provided with simple structural means.
  • FIG. 1 shows a basic representation of an opening device in a side view of an opening device which is integrated in a door element.
  • FIG. 1 shows a basic representation of a positioning device 1 in a side view of a door element 2 , an adjusting means 3 and a motor vehicle body 4 .
  • FIG. 1 shows the open position of the door element 2, ie the position of the door element 2 in which the door element 2 is moved by the opening device 1 was, so that a door gap S between body 4 and door element 2 results.
  • the positioning device has an electric drive 5 , a spindle gear 6 , a Bowden cable 7 , a lever mechanism 8 , a spring accumulator 9 , an adjusting means 3 , a buffer element 10 and a housing 11 .
  • the open position of the door element 2 is shown, with the actuating means 3 being shown moved out of an opening 12 in the door element 2 .
  • the door element 2 was moved by means of the actuating means 3 in the process.
  • FIG. 1 shows the relaxed spring accumulator 9.
  • the spring accumulator 9 is equipped with a compression spring 13 , the compression spring 13 being held in the actuating means 3 by means of a guide 14 .
  • the guide 14 for the compression spring 13 is only shown in principle, the guide 14 of course completely integrating the compression spring 13 and thus being able to guide it.
  • the electric drive 5 controls the movement of the actuating means 3.
  • a lever mechanism 8 acts on the actuating means 3.
  • a pivotable connection 15 is firmly connected to the adjusting means 3 .
  • the Bowden cable 7 in turn is also connected to the lever mechanism 8 via the connection 16 .
  • the Bowden cable 7 in turn is connected to the spindle gear 6 so that a tensile force F can be introduced into the lever mechanism 8 and thus the actuating means 3 by means of the Bowden cable 7 .
  • the lever mechanism 8 is pivoted in the direction of the arrow P, so that the lever mechanism 8 is in the tensioned position shown as a dashed line L location can be transferred.
  • the actuating means 3 is consequently pulled back into the opening 12 by the tensile force F and at the same time the spring accumulator 13 is tensioned.
  • the spindle gear 6 moves in an effective direction and moves the actuating means 3 into the initial position, which preferably aligns the actuating means 3 flush with the opening 12 . If the spindle drive is moved in the opposite direction, the actuating means 3 can be moved out of the opening 12 again.
  • the force of the compression spring 13 also acts on the actuating means 3, so that only small forces have to be made available in the electric drive 5, which means that the actuating means 3 and the door element 2 can be set quickly.
  • the opened door element 2 can be closed again against the force of the compression spring 13 without damaging the positioning device 1 . Furthermore, when setting up, the force acting on an obstacle, for example, is limited by the maximum acting spring force.
  • the opening device 1 is integrated into the door element 2 according to FIG.
  • the housing 11 can be arranged as a separate component in the door element 2, the housing being made of plastic, for example.
