Description

[0001] The present invention relates to a drive system for a movable element articulated to a superordinate structural unit, a movable element with a drive system and the use of a drive system.

[0002] Movable elements such as doors or hatches for trucks or passenger cars, some of which have a high deadweight, feature force-assisted springs or drives to facilitate opening. Numerous designs are known from the prior art. Examples of force-assisted springs include gas springs or struts. Electric or electromechanical drives, in particular, offer particularly convenient, partially automated movement of the hatch. An electric drive for a hatch is known, for example, from EP1767439A2.

[0003] At the same time, the movable elements must be equipped with a locking mechanism to prevent accidental opening. Common locks in this context include purely mechanical or electromechanical locks, the latter sometimes combined with so-called closing aids.

[0004] On the other hand, DE102017008267A1, for example, discloses a door drive with a lever arrangement coupled to an electric motor and a door leaf. The lever arrangement has a first and a second over-center position, with the second over-center position enabling burglary and theft protection. A particular disadvantage here is the complex and space-intensive design.

[0005] The object of the invention is to enable, by simple means, an automated movement of a movable element hinged to a higher-level structural unit and, at the same time, a secure, robust and cost-effective locking of the element to the higher-level structural unit.

[0006] According to the invention, this object is achieved with regard to the drive system by the subject matter of claim 1.

[0007] Specifically, the problem is solved by a drive system for a movable element articulated to a higher-level structural unit, with an electric drive for the automated movement of the movable element, wherein the electric drive has at least one fixed drive component articulated to the movable element or the higher-level structural unit and a drive component that is movable relative to the fixed drive component, wherein the movable element is opened when the drive is extended and closed when the drive is retracted. Furthermore, the drive system has a locking mechanism that can be actuated by means of the drive for locking the movable element to the higher-level component, wherein the drive is additionally provided as an actuator for the locking mechanism that is arranged at least partially on the movable element and that can be opened or closed when the movable drive component travels through an idle stroke.is lockable and has at least one locking link and one locking element.

[0008] The locking link is provided to be directly or indirectly connected to the higher-level structural unit or the moving element and has a locking contour into which the locking element connected to the movable drive component or the higher-level structural unit is designed to engage in order to lock the movable element.

[0009] The movable element is, for example, a flap, door or other foldable element for a motor vehicle or another higher-level structural unit.

[0010] The invention allows an electric or electromechanical drive, which is primarily used to move the movable element into an open and closed position, to be additionally provided as a passive element for controlling a locking mechanism of the movable element. This eliminates the need for a separate locking actuator with a separate control unit, resulting in a cost-effective, space-saving overall system for a movable element. At the same time, an internal locking mechanism can be implemented in a simple and cost-effective manner.

[0011] The locking gate, formed with the locking contour, allows for secure locking. At the same time, it can be easily constructed, allowing for a complex design with minimal installation space.

[0012] In an advantageous embodiment of the invention, the locking link is designed as a locking bracket with the locking contour connected to the parent component. The locking bracket, which enables a simple yet robust design, can be connected directly or indirectly to the parent component.

[0013] According to an advantageous embodiment, the locking element can be designed as a locking pin connected to the movable drive component. The pin shape allows the use of a cost-effective standard component.

[0014] The locking pin can preferably be centrally mounted on the movable drive component such that both ends can engage the locking contour of the locking bracket. This ensures locking even with movable elements that have a high dead weight or are designed with a large surface area.

[0015] A particularly simple and safe guidance into a locking position can be achieved by providing an articulated eye with an elongated hole that is directly or indirectly connected to the movable element for the articulated connection of the movable drive component to the movable element, wherein the locking element is guided in the elongated hole of the articulated eye.

[0016] According to another advantageous development of the invention, the locking element can be designed as a rotary latch mounted eccentrically on the movable element and connected in an articulated manner to the movable drive component. The locking link is designed as a stop connected to the superordinate structural unit, against which a cam formed on the rotary latch can be engaged in a retracted end position of the drive. The locking element is simply designed and allows for reliable and robust locking in the locking position of the movable element.

[0017] The rotary latch preferably has a projection which is provided to limit the angle of rotation of the locking element.

[0018] According to an alternative advantageous development of the invention, the locking element can be designed as a catch bolt connected to the superordinate component unit and the locking framework can be designed as a tab into which the catch bolt is provided to engage for locking, wherein the movable element is designed to be displaceable in a vertical direction in the superordinate component unit and can be moved into a locking position in an end region of the insertion of the drive and into an opening position when the drive is withdrawn. This configuration of the invention allows for a particularly simple connection of the drive to the movable element. At the same time, the locking mechanism can be simply configured.

[0019] Preferably, the superordinate component has vertically aligned long holes, whereby the vertical displacement of the movable element can be formed in a simple manner with a hinge unit.

[0020] According to another advantageous development of the invention, the locking element can be constructed in several parts and have at least two actuating elements positioned spatially apart from one another on the flap. This design allows for particularly flexible adaptation to given installation space positions.

[0021] Preferably, the locking element can have a first and a second actuating element, wherein the first actuating element is rotatably mounted on the flap and is articulated to the movable drive component, and the second actuating element comprises a latch which can be actuated by means of the first actuating element and is rotatably mounted on the movable element and which can engage in a locking link designed as a tab in a retracted end position of the drive.

[0022] According to an advantageous embodiment of the invention, the locking link can be moved by means of the drive into a locking position in which the locking element engages in a locking contour of the locking link.

[0023] Preferably, the locking gate can be designed so that it can be disengaged from the locking element without actuating the electric drive. This makes it possible to easily provide an additional unlocking mechanism. This can be provided as an additional, manual unlocking mechanism.

[0024] According to a particularly advantageous embodiment, the locking link is provided so as to be movable into a first position in which it can be brought into engagement with the locking element and a second position in which it is disengaged from the locking element.

[0025] Preferably, a preloading element is provided, by means of which the locking bracket or the locking contour is held in the first position. By means of the preloading element, the locking bracket can be automatically returned to the first position after actuation.

[0026] The locking link can be designed in several parts and have at least the locking bracket comprising the locking contour and a further bracket element, wherein the further bracket element is arranged on the higher-level structural unit.

[0027] In a particularly preferred embodiment of the invention, the locking bracket is guided on the additional bracket element and is designed to be displaceable relative to the additional bracket element. This makes the locking mechanism particularly robust. The locking bracket's guidance allows for reliable actuation without actuating the electric drive.

[0028] The invention further relates to a movable element with a drive system. The drive system can move the movable element automatically using simple means as described above and simultaneously lock it reliably.

[0029] The invention relates to the use of a drive system for the automated movement of a movable element, wherein the movable element is a flap, a door, or a hood, in particular for a motor vehicle. The motor vehicle can be, for example, a passenger car, a truck, or a bus.

[0030] The invention further relates to the use of a drive system for the automated movement of a movable element, wherein the movable element is a table that can be attached to a wall or a frame arranged on the wall as a superordinate structural unit. The table or wall-mounted table can preferably be folded in, so that a table frame and a tabletop are arranged in a space-saving manner. The drive system enables convenient movement (folding and unfolding of the table) and, at the same time, secure locking of the table to the wall.

[0031] The present invention will be described below using several exemplary embodiments. Identical or similar components are provided with the same reference numerals. The drawings, the description, and the claims contain numerous features in combination. Those skilled in the art will expediently consider the features individually and combine them into further meaningful combinations.

[0033] The Fig. 1 to 3 show a first exemplary embodiment of a drive system 10 according to the invention for a movable element 12. The movable element 12 can, for example, be a flap or a door of a passenger or commercial vehicle. A possible use of the drive system according to the invention can also be in the furniture industry. One example is the use for a foldable table, which can be folded in and out by means of the drive system 10 according to the invention and can be locked to a wall frame or a wall as a superordinate structural unit. The use in mechanical engineering, and in particular for machine flaps or building flaps, is also mentioned.

[0034] The movable element 12, which is in Fig. 1 as a movable model articulated to a schematically represented model of a higher-level structural unit 14, can, as already mentioned, be, for example, a rear or hood flap or a side flap for a truck, passenger car, or bus. The higher-level structural unit 14 in this case is the body of the motor vehicle.

[0035] The drive system 10 for the movable element 12 comprises at least one electric drive 16 for the automated movement of the movable element 12, wherein the drive 16 is additionally provided as an actuator for a locking mechanism 18 arranged at least partially on the movable element 12. The invention thus allows an electric or electromechanical drive 16, which is primarily used for moving the movable element 12 into an open and a closed position, to be additionally provided as a passive element for controlling a locking of the movable element 12. However, use as an actuator does not necessarily mean that the drive 16 is directly connected to the locking mechanism 18, as will become clear from the following description of some exemplary embodiments.

[0036] The drive 16 is designed, for example, as a spindle drive and has at least one fixed drive component 20 that is pivotally connected to the superordinate structural unit 14, as well as a drive component 22 that is movable relative to the fixed drive component 20 and connected to the locking mechanism 18. In addition to the drive 16 shown, it is possible to provide a further spring means or a further drive for force support.

[0037] The movable element 12 is opened when the drive 16 is extended and closed when the drive 16 is retracted. The locking mechanism 18 is actuated when the drive 16 is retracted such that the movable element 12 is closed by the locking mechanism 18. In contrast, when the drive 16 is extended, the locking mechanism 18 can be opened.

[0038] Specifically, the locking mechanism 18 interacts with the electric drive 16 in such a way that the movable element 12 is locked by retracting the drive 16 in a retraction end region and is released by extending the drive 16 in an extension start region. This means that the locking mechanism 18 can be opened or closed when the movable drive component 22 travels through an idle stroke.

[0039] Shortly before a retracted end position of the drive 16 is reached, the movable element 12 is moved into a closed position in which it comes into contact with a stop 24 of the higher-level structural unit 14.

[0040] From the Fig. 2 and Fig. 3 the positions of the locking mechanism 18 can be clearly seen. Fig. Figure 3 shows the opened locking mechanism 18. In this position, the movable element 12 rests against the stop 24 of the superordinate assembly 14 and the drive 16 is not yet fully retracted, i.e., is not yet in its retracted end position. By passing through the end range, the locking mechanism 18 is moved into a locking position, which is Fig. 2. In this position, the movable element 12 is locked and can no longer be opened by manual force. The lock is released only when the drive 16 extends, i.e., when the drive passes through the initial extension range or the idle stroke. When passing through this range, only the locking mechanism 18 is initially opened. Only further extension of the drive 16 opens the movable element 12.

[0041] The locking mechanism 18 of this embodiment has, as shown in the Fig. 2 and Fig. 3, a locking link 26 connected to the higher-level structural unit 14 and a locking element 28 connected to the relatively movable drive component 22. In this example, the locking link 26 is designed as a locking plate or as a locking bracket 29 with a locking contour 30, into which the locking element 28, designed here, for example, as a locking pin or pin, engages to lock the movable element 12.

[0042] Like the Fig. 2 and Fig. 3, the locking pin is fastened centrally to the movable drive component 22 in such a way that both ends engage in the locking contour 30 of the locking bracket 29.

[0043] The locking contour 30 is designed, for example, as an inclined plane, so that it is possible to exert a preload on a seal (not shown) for the movable element 12 when the drive 16 is retracted, thus ensuring the sealing of the movable element 12. Other contours are also conceivable. Lead-in chamfers 36 facilitate the insertion of the locking element 28 into the locking contour 30 of the locking link 26.

[0044] A joint eye 32, which is connected in an articulated manner to the movable element 12 and has an elongated hole 34 through which the locking element 28 is guided in an axially displaceable manner, enables simple and secure guidance of the locking element 28.

[0045] In the Fig. 4 to 6, a second embodiment of a drive system 10 according to the invention is shown, wherein analogously to the embodiment described above Fig. 4 a spatial model and the Fig. 5 and Fig. 6 shows a section of the drive system 10.

[0046] In the second embodiment, the locking element 28, in contrast to the first embodiment, is designed as a rotary latch mounted eccentrically on the movable element 12 and connected to a non-recognizable joint eye of the movable drive component 22. The locking link 26 arranged on the superordinate structural unit 14 is designed as a stop against which a cam 38 formed on the rotary latch with a stop surface 39 can be struck in a retracted end position of the drive 16, as can be seen from Fig. 5, which shows a locked position of the locking mechanism 18. The stop has a corresponding counter-stop surface 41 for this purpose.

[0047] When the drive 16 is extended, a projection 43 arranged on the rotary latch enables a limited rotation of the rotary latch, which comes into contact with the movable element 12 and thus limits the idle stroke of the drive 16.

[0048] In the Fig. 7 to 9, a third embodiment of a drive system 10 according to the invention is shown, wherein analogously to the embodiment described above Fig. 7 a spatial model and the Fig. 8 and Fig. 9 shows a section of the drive system 10.

[0049] The locking element 28 in this example is designed as a catch bolt connected to the higher-level structural unit 14, and the locking link 26 is designed as a tab connected to the movable element 12. The catch bolt engages in the tab-shaped locking contour for locking in a retracted end position of the drive 16. To enable the necessary relative movement between the tab and the catch bolt, in this embodiment the movable element 12 is mounted displaceably in the vertical direction in elongated holes 40 of the higher-level structural unit 14. This means that the movable element 12 is in an end region of the retraction of the drive 16 into a locking position ( Fig. 8) and when the drive is extended into an opening position ( Fig. 9) movable.

[0050] In the Fig. 10 to 12, a fourth embodiment of a drive system 10 according to the invention is shown, wherein analogously to the embodiment described above Fig. 10 a spatial model and the Fig. 11 and Fig. 12 shows a section of the drive system 10.

[0051] The illustrated embodiment differs from the embodiments described above in particular in that the locking element 28 is formed in several parts and has at least two actuating elements (here a first and a second actuating element 42, 44) positioned spatially apart from one another on the movable element 12. The first actuating element 42 is - as in the Fig. 11 and Fig. 12, is rotatably mounted on the movable element 12 and connected to a non-visible joint eye of the movable drive component 22. The second actuating element 44 comprises a latch 46 which can be actuated by means of the first actuating element 42 and is rotatably mounted on the movable element 12 and which, in a retracted end position of the drive 16, can engage in a locking link 26 with a tab-shaped locking contour 30. The actuation of the second actuating element 44 can, for example, be carried out in a simple manner by means of a Bowden cable 48.

[0052] Fig. 13 shows a section of a further, fifth embodiment with the lock open. As the first embodiment according to the Fig. 1 to 3, a joint eye 32 is provided which is articulated to the movable element 12 and has an elongated hole 34 in which a locking element 28 connected to the displaceable drive part 22 is guided for axial displacement. In contrast to the first exemplary embodiment, the locking element 28 is connected to a further locking element 52 via a suitable bearing or joint 50. This can be designed, for example, as a plunger and is guided on the movable element 12 by means of a guide element 54. In a locking position, the further locking element 52 engages in a suitable locking slot 56 with a locking contour (not shown in detail) at the end of the flap 12.

[0053] If the locking link 56 is connected to the higher-level unit 14, the Fig. 13, the locking link 26 is also omitted. The guide element 28 functions merely as a connecting element.

[0054] For emergency release of the movable element 12, it may be advantageous to provide at least one component of the locking mechanism 18 of the described embodiments so that it can be detachably removed from the locking gate. The release can be performed manually, for example. To restore the locking, the detachable component can be spring-loaded, for example.

[0055] Further, not shown, embodiments of the invention provide for the locking link to be movable. The locking link can be arranged so that it slides on the superordinate component 14 or the movable element 12 and can be moved between a locking position and an opening position by means of the drive 16. A locking element is accordingly arranged on the movable element 12 or on the superordinate structural unit 14 and can be designed, for example, as a bolt.

[0056] To achieve an emergency release, it is conceivable to release the bolt from the locking gate using a suitable traction device. If the bolt is spring-loaded in the locking direction by a compression spring, the locking can be restored using a suitable contour of the locking gate.

[0057] Fig. 14 shows a three-dimensional view of a locking link 26 with an adjacent locking element 28 of a further, specific embodiment. As can be seen, the locking element 28 is designed, similar to the second embodiment, as a rotary latch mounted eccentrically on the movable element 12. The locking link 26 arranged on the higher-level structural unit 14 comprises a plate element 58 with a hook element 60 arranged thereon as the locking contour 30. In the closed position of the drive 16, the stop surface 39 of the rotary latch rests against the counter-stop surface 41 of the locking link 26.

[0058] The projection 43 formed on the rotary latch has a recess 62 in which, for example, a Bowden cable can be fastened for manual unlocking.

[0059] The Fig. 15 to 18 show a further exemplary embodiment in various positions of a locking mechanism 18, which differs from the first exemplary embodiment in that the locking link 26 is formed in several parts and has at least one locking bracket 29 comprising the locking contour 30 and a further bracket element 64. The further bracket element 64 is provided for attachment to the superordinate structural unit 14.

[0060] The locking link 26 of this embodiment has a first and a second position, wherein the locking bracket 29 with the locking contour 30 can be moved to a limited extent relative to the further bracket element 64.

[0061] The first position is in Fig. 15, in which the locking element 28 is engaged with the locking contour. The element 12 (not shown) is not movable in this position, i.e., locked.

[0062] In the second position, which is Fig. 16, the locking bracket 29 is shown displaced upward in the drawing. This second position enables movement of the movable element 12, since the locking element 28 no longer engages with the locking contour 30. The displacement of the locking bracket 29 is possible without actuating the electric drive 16 in that traction means (not shown) engage a bolt-like guide element 66, which is attached to the locking bracket 29 by an upper and a lower end 68, 70.

[0063] How Fig. 16, the guide element 66 extends through rear guide tabs 72 of the further bracket element 64, which surrounds the locking bracket 29 on both sides with lateral guide tabs 74.

[0064] When the locking bracket 29 is actuated, the lateral guide tabs 74 push the ends of the pin-shaped locking element 28 out of the locking contour and thus enable the locking mechanism 18 to be opened without actuating the drive 18.

[0065] A pretensioning element 76 in the form of a compression spring is arranged between a lower rear guide tab 72 of the further bracket element 64 and the second, lower end 70 and tensions the locking bracket 29 in the direction of its first position ( Fig. 15). The pretensioning element 76 is compressed when the locking bracket 29 is displaced upwards in the drawing, so that after actuation the locking bracket 29 is returned from the second position to the first position.

[0066] The Fig. 17 and Fig. 18 shows two opening positions in an automated process by the drive 16.

[0067] Two further embodiments, which show a locking mechanism 18 in particular for a table that can be folded or folded against the wall, are shown in the Fig. 19 to 21.

[0068] As can be seen, the locking mechanism 18 has a pin-shaped locking element 28, which is similar to the locking elements shown in the Fig. 1 to 3 and 15 to 18 is movable in a joint eye 32.

[0069] The locking link 26 of the Fig. 19 and Fig. The embodiment shown in Figure 20 is plate-shaped and attached to the superordinate structural unit 14. In this case, the superordinate structural unit 14 is, for example, a frame attached to a wall, which serves to link the folding table and lock it. Table legs are attached to the frame or a mechanism attached to it, which can be moved manually or automatically simultaneously with the folding movement of a table top.

[0070] The drive 16 is specifically arranged in a mechanism of the table (not shown) in such a way that extending the drive 16 results in the mechanism unfolding. The tabletop is folded down from the wall. When the drive 16 is retracted, the table folds in, or the tabletop is folded against the wall, and is locked to the wall or frame in the retracted end position of the drive 16.

[0071] A folded table position corresponds to a closed position or the locking position of a door or flap element. A folded table position, on the other hand, corresponds to an open position or the opening position of a door or flap element.

[0072] The locking link 26 has one, preferably two spring-loaded snap elements 78 as a locking contour 30, which can be pressed in during retraction.

[0073] Fig. 21 and Fig. 22 shows a final embodiment which differs from the previous embodiment according to the Fig. 19 and Fig.20 in that the locking link 26 can engage in a recess 80 of the joint eye 32, so that the locking element 28 can be locked within the joint eye 32 with the locking contour 30. In this embodiment, the locking contour 30 is also a snap element 78, which is arranged on a holding rod as a locking link 26. QUOTES CONTAINED IN THE DESCRIPTION
