Definitions
- Motor vehicle with a wing element and an adjusting device for moving the wing element and adjusting device for moving a
- the invention relates to a motor vehicle which comprises at least one wing element movably held at at least one bearing point of the motor vehicle and at least one adjusting device for moving the wing element.
- a second aspect of the invention relates to an adjusting device for moving at least one wing element of a motor vehicle.
- wing elements in particular wing elements that open against gravity, such as tailgates, for example, are often opened and / or closed by an electric motor.
- This allows a comfortable and safe opening or closing of the wing element for people with disabilities, for example wheelchair users, or people who, for example, do not have a hand free for manual operation of the wing element after a purchase.
- gas springs are frequently used when moving tailgates, as can be seen for example in the documents DE 10 2006 016 826 A1 or DE 10 2006 055 192 B3.
- the object of the present invention is to provide a motor vehicle and an adjustment device of the type mentioned at the outset, by means of which an uncontrolled movement of the wing element between an open position and a closed position of the wing element can be avoided in the event of damage.
- a first aspect of the invention relates to a motor vehicle, comprising at least one wing element movably held at at least one bearing point of the motor vehicle and at least one adjusting device by means of which the at least one wing element is between a closed position in which the wing element is an opening of the motor vehicle is closed and at least one open position is displaceable, the at least one adjusting device comprising at least one spring component which on the one hand is at least indirectly coupled to the at least one wing element and on the other hand at least indirectly to a holding area of the motor vehicle and which comprises at least one sleeve element and at least one piston element , which is at least partially inserted into a sleeve interior of the sleeve element and relative when the at least one wing element is displaced between the closed position and the at least one open position to the at least one sleeve element is slidable ver.
- the wing element can be designed, for example, as a tailgate.
- the wing element can be designed, for example, as a bonnet.
- the wing element can be designed as a vehicle door, for example.
- a shift from the closed position to the open position can take place against gravity.
- the wing element can be displaced from gravity from the closed position into the at least one open position.
- the sleeve element can have an inner lateral surface, which can also be referred to below as the inner surface, on which the sleeve element can be displaceably guided. Last but not least, due to the low cost of producing the sleeve element, it is expedient if the inner surface of the sleeve element is cylindrical.
- the piston element can be displaceable relative to the sleeve element in particular depending on the displacement of the wing element between its at least one open position and its closed position.
- the piston element can be connected at least indirectly to the bearing point of the motor vehicle.
- the sleeve element can be connected at least indirectly to the wing element.
- the sleeve element can be connected at least indirectly to the bearing point of the motor vehicle and the piston element can be connected at least indirectly to the wing element.
- the at least one spring component is designed as a spring strut and comprises at least one damping device for damping when the at least one piston element is displaced relative to the at least one sleeve element when the wing element is displaced between the at least one open position and the closed position.
- the spring strut can counteract a displacement of the wing element during its movement between the at least one open position and the closed position by applying spring force to the wing element and thereby prevent, for example, an uncontrolled closing of the wing element in the direction of the closed position.
- the damping device can counteract the displacement of the wing element during its movement between the at least one open position and the closed position by damping force on the wing element and thereby also contribute, for example that to prevent uncontrolled movement of the wing element in the direction of the closed position or in the direction of the open position.
- the wing element can be effectively decelerated and thus braked when it is displaced between the at least one open position and the closed position.
- the piston element and the damping device can preferably be formed in one piece.
- the piston element and the damping device can be connected to one another in one piece.
- the sleeve element and the damping device can advantageously be formed in one piece.
- the sleeve element and the damping device can be connected to one another in one piece. This enables particularly low-effort assembly, in particular simultaneous assembly of the sleeve element and the damping device.
- the invention is based on the knowledge that conventional gas springs known from the prior art are insufficient in the damage cases mentioned, in which a weight force of the wing element, for example due to tearing out of an anchorage of a drive motor when the wing element is open, can only act suddenly on the gas springs can contribute to the deceleration of the wing element during its movement.
- tension springs are sometimes used in gas springs known from the prior art, which can even cause the wing element to accelerate when it moves.
- an effective deceleration that is to say braking of the wing element when it moves between the open position and the closed position, for example in the direction of the closed position, can be brought about . In other words, braking can take place in all adjustment directions of the wing element Act.
- shock absorber and the damping device Another advantage of the shock absorber and the damping device is that these possible pivoting movements of the wing element can be counteracted in different, in particular opposite, adjustment directions during the assembly of different components of the wing element. This is advantageous because an effective deceleration in the different adjustment directions can thus be achieved by the spring strut and the damping device even when the weight of the wing element changes during the assembly of the components of the wing element. If, for example, the wing element is still light in an early assembly stage, since some components, such as a washer (for example, in the case of a wing element designed as a patch flap) have not yet been installed, the shock absorber and damping device can move suddenly, for example Avoid (e.g.
- spindle drives for moving the wing element can be protected from damage in this early stage of assembly.
- Such spindle drives are designed for the movement of the wing element after completion of the assembly of the components. In the event of a sudden movement, there would be a risk of damage to such a spindle drive, which can be avoided by the shock absorber and damping device.
- a medium contained in the sleeve interior is between at least two interior partial areas of the sleeve interior which are delimited from one another at least in regions by a piston element region of the at least one piston element interchangeable.
- the medium can thus be moved in the interior of the sleeve, that is to say inside the sleeve element, so that a damping effect can be achieved by exchanging the medium between the interior parts.
- the damping effect can then be achieved by displacing the medium from one of the interior sub-regions into the other interior sub-region. Exchanging the medium between the interior part areas prevents the medium from escaping into the surroundings of the sleeve element. Accordingly, environmental influences, for example the entry of contaminants from the environment into the interior of the sleeve, can also be excluded.
- the damping device in such a way that the medium can be exchanged between the interior of the sleeve and the surroundings of the sleeve element, as a result of which a damping effect can be achieved with particularly little effort.
- the damping device for example, as a particularly simple through opening through a sleeve element wall of the sleeve element, via which the medium can be exchanged between the sleeve interior and the surroundings.
- the damping device comprises at least one bypass which extends in the axial direction of extension of the spring component at least over a partial region of the sleeve element and via which the medium can be exchanged between the at least two inner partial regions.
- the bypass is particularly easy to manufacture, as a result of which the exchange of the medium between the interior part areas can be implemented with little effort.
- the bypass can serve for the medium and allow the medium to flow within the bypass and relative to the piston element.
- the medium can be exchanged throttled by the bypass between the interior parts, whereby a damping effect can be achieved.
- the bypass can be designed, for example, as a groove or as a channel, in order to to name games.
- At least two bypass subregions of the bypass can each have subregional cross sections that are different from one another and oriented perpendicular to the direction of axial extent.
- the damping effect can be changed in a particularly effortless manner. Due to the different partial area cross sections, a flow velocity of the medium when flowing through the bypass partial areas and, depending on this, also a displacement speed of the piston element when it is displaced relative to the sleeve element can be varied.
- the at least two bypass subregions of the bypass can result in a particularly simple end position damping when the piston element is displaced in the direction of at least one sleeve element end of the sleeve element.
- the damping device comprises at least one overflow opening which extends at least through the piston element region in the axial direction of extension of the at least one spring component and via which the medium can be exchanged between the at least two interior partial regions.
- the damping device can preferably comprise a valve with a valve body, which between a valve open position in which the valve body opens the overflow opening for the exchange of the medium and a valve closed position in which the valve body the overflow opening for the exchange of the Medium blocked, can be relocatable.
- the Valve may include a valve spring to displace the valve body between the valve open and valve closed positions.
- the valve body can for example be designed as a ball.
- the valve can be designed, for example, as a check valve, as a result of which damping that is dependent on a direction of movement of the piston element relative to the sleeve element can be achieved. For example, when moving the wing element from the open position to the closed position, particularly strong damping can be achieved if the valve body is held in the valve-closed position.
- the overflow opening is narrowed at least in some areas. This is advantageous because, for example, the constriction enables simple valve retrofitting, the constriction being able to form a valve seat.
- the overflow opening which is narrowed in some areas, can form a nozzle.
- the at least one spring component comprises at least one compression spring, by means of which at least indirectly a spring force can be exerted on the at least one wing element in order to move the at least one wing element between the closed position and the at least one open position by the spring force support.
- the compression spring contributes in a particularly favorable manner to braking the wing element during its movement.
- the compression spring can exert the spring force as a compression force.
- the compression spring By means of the compression spring, the displacement of the at least one wing element from the closed position into the at least one open position can be supported, as a result of which the wing element can be opened with particularly little effort.
- the compression spring In contrast to systems known from the prior art, in which tension springs are frequently used, which bring about an accelerated closing of wing elements, the compression spring enables one effective delay of relocation between the open position and the closed position. In other words, the compression spring can thus particularly effectively reduce a speed of movement of the wing element when moving from the at least one open position into the closed position.
- the at least one compression spring can be pretensioned in all positions of the piston element relative to the sleeve element and exert the spring force at least indirectly on the holding area on the one hand and on the wing element on the other hand.
- the spring component can permanently counteract the displacement or movement of the wing element from the at least one open position into the closed position, as a result of which dangerous closing of the wing element can be prevented particularly effectively.
- the adjusting device has at least one additional spring component which is at least indirectly coupled to the at least one wing element on the one hand and at least indirectly to an additional holding area of the motor vehicle and by means of which one, the displacement of the at least one wing element between the closed position and the at least one open position supporting additional spring force can be exerted on the at least one wing element.
- the spring component and the additional spring component can be coupled to the wing element on opposite sides of the latter.
- the additional spring component can be designed, for example, as a gas spring or as a further spring strut.
- the adjusting device comprises at least one actuator, by means of which an actuator force can be exerted at least indirectly on the at least one wing element is to move the at least one wing element between the closed position and the at least one open position.
- an actuator force can be exerted at least indirectly on the at least one wing element is to move the at least one wing element between the closed position and the at least one open position.
- a wing element designed as a patch flap can be moved from the closed position into the at least one open position in the direction of gravity.
- the shock absorber and damping device effectively delay the movement, but the movement can also be supported by the actuator.
- the adjusting device comprises at least one spindle which is coupled on the one hand to the actuator and on the other hand to the wing element.
- the spindle can be used to convert a rotary movement of a drive shaft of the actuator into a translatory movement in a particularly simple manner.
- the additional spring component can be coupled to the spindle and can be telescopic, for example by driving the spindle by means of the actuator, to name just one example.
- a second aspect of the invention relates to an adjusting device for displacing at least one wing element of a motor vehicle, by means of which the at least one wing element can be displaced between a closed position, in which the wing element closes an opening of the motor vehicle, and at least one open position
- the at least one Adjustment device comprises at least one spring component, which is designed on the one hand for at least indirect coupling with the at least one wing element and on the other hand for at least indirect coupling with a holding area of the motor vehicle and which at least comprises a sleeve element and at least one piston element which is at least partially inserted into a sleeve interior of the sleeve element and can be displaced relative to the at least one sleeve element when the at least one wing element is displaced between the closed position and the at least one open position.
- the at least one spring component is designed as a spring strut and comprises at least one damping device for damping when the at least one piston element is displaced relative to the at least one sleeve element when the wing element is displaced between the at least one open position and the closed position.
- This adjustment device can prevent an uncontrolled movement of the wing element between an open position and a closed position of the wing element in the event of damage.

- the compression spring 50 is designed as a helical spring. Both the sleeve element 30 and the piston element 40 are circumferentially surrounded by the compression spring 50. In other words, both the sleeve element 30 and the piston element 40 are inserted into the compression spring 50.
- the piston rod region 44 is coupled to the first connection element 22 via a first disk element 46 of the spring component 20.
- the sleeve element 30 is on one, the first disc element 46 in axial Direction of extension R_A opposite, second disc element 48 of the spring component 20 attached.
- the sleeve element 30 is coupled to the second connection element 24 via the second disk element 48.
- the first disk element 46 and the second disk element 48 are designed as respective support disks, between which the compression spring 50 is clamped.
- the spring component 20 further comprises a first protective sleeve 26 and a second protective sleeve 28.
- the two protective sleeves 26, 28 are arranged one inside the other and thereby form a telescopic protective sleeve arrangement surrounding the compression spring 50, the sleeve element 30 and the piston element 40 in the circumferential direction.
- the first protective sleeve 26 is inserted into the second protective sleeve 28.
- the first protective sleeve 26 is connected to the first disk element 46, whereas the second protective sleeve 28 is connected to the second disk element 48.
- a controlled drop can occur in the event of damage, for example if the actuator 90 fails or if the connection between the additional spring component 80 and the wing element 110 is released, to name just a few examples , that is, a controlled pivoting of the wing element 110, which is embodied here as a tailgate, from the open position 112 into the closed position 114 is ensured.
- the spring component 20 or the damping device 60 which is designed as a spring strut, enables the piston element 40 to retract into the sleeve element 30 in the direction of the arrow in the axial direction of extension R_A, thereby braking the wing element 110 during its pivoting movement from the open position 112 to the closed position 114. whereby serious injuries of people standing in the pivoting range of the wing element 110 can be at least largely avoided.
- the damping device 60 provides insertion damping during the pivot the wing member 110 provided.
- the actuator 90 is at least indirectly coupled to the so-called active side of the wing element 110.
- the spring component 20 is coupled to the wing element 110 on an opposite, so-called passive side of the wing element 110. If the described damage occurs, the damping device 60 or the spring component 20 designed as a spring strut can be used to lower the wing element 110 in a controlled manner against the direction of the arrow in the vertical direction y.
- the groove 62 (bypass) can be As can be seen in FIG. 3, extend in or along the sleeve element 30, the sleeve element 30 also being able to be referred to as a pressure tube.
- the overflow opening 64 can be designed as a nozzle in the piston element 40 or in the piston element region 42 in order to provide the desired insertion damping. A particularly advantageous damping effect can be achieved if both the groove 62 and the overflow opening 64 are provided.
- the damping device 60 can also provide extension damping, so that a so-called “opening” of the wing element 110, in other words a particularly rapid pivoting movement of the wing element 110 from the closed position 114 into the open position 112, can be avoided. By avoiding this “opening”, injuries or damage to the actuator 90 can also be prevented.
