Description

Technical Field

[0001] The present invention relates to a drive device for a wing fan of a window or door, the drive device comprising at least one actuator for moving the wing fan relative to a fixed frame by means of flexible pulling and pushing elements, wherein the actuator includes connecting wires connected to the actuator for power supply and / or operation; and the drive device having a fixing structure, in particular a bracket, for fixing the actuator to the wing fan or frame. Background Technology

[0002] Such drive mechanisms are known in principle. In drive mechanisms to date, it has been stipulated that relatively long connecting wires are connected to the drive, for example, by means of soldering or screwing the connecting wires to the drive. These connecting wires are used to power and / or operate the drive and are typically up to 2 meters long.

[0003] For maintenance purposes, it has proven problematic that in order to disassemble the drive unit, the entire connecting cable must be replaced together, which has proven difficult, especially when the connecting cable is mounted on the wing or breech, or that to disconnect the connecting cable, the housing containing the drive unit must first be opened to access the connection point of the connecting cable on the drive unit. Both methods are very complicated. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide a drive device that is easier to maintain and, in particular, the driver is easier to replace.

[0005] This task is solved by a drive device, and in particular by means of an electrical connection mechanism arranged separately from the driver on a fixed structure, the electrical connection mechanism including a supply interface for electrically connecting the connection mechanism to a power supply and / or a control unit, and the electrical connection mechanism having a drive interface electrically connected to the supply interface, through which the driver is electrically connected to the connection mechanism via its connecting wires.

[0006] The present invention is based on the concept that the driver is not directly connected to the power supply and / or control unit via its connecting wires, but is connected to a separate electrical connection mechanism that is intermediate between the interface and the power supply and / or control unit, and that electrical connection mechanism is itself electrically connected to the power supply and / or control unit.

[0007] The electrical connection mechanism is arranged on the mounting structure for securing the driver and is therefore located near the driver. Since the driver is not directly electrically connected to the power supply and / or control unit, but only to the connection mechanism, a shorter connecting wire can be used compared to the connecting wire that directly connects the driver to the power supply and / or control unit, thus bridging the short distance between the electrical connection mechanism and the driver. Therefore, to disassemble the driver, it is no longer necessary to completely disconnect the connecting wire that connects the driver to the power supply and / or control unit together. Instead, it is only necessary to disconnect the connecting wire connecting the driver and the connection mechanism from the connection mechanism, thereby simplifying the replacement and / or maintenance of the driver overall. The connecting wire connecting the driver and the connection structure can, for example, have a length between 2 and 10 cm, preferably between 3 and 7 cm. Particularly preferably, the length of the connecting wire is 5 cm.

[0008] Advantageous embodiments of the invention can be deduced from the description and drawings.

[0009] According to a particularly simple design of the drive device, the supply interface and / or drive interface of the electrical connection mechanism are respectively configured as connection bushings or connection interfaces, and in particular, the supply interface and drive interface are electrically connected to each other by means of a cable. However, the electrical connection mechanism can also be constructed on a circuit board with integrated wires, wherein the integrated wires electrically connect the supply interface and drive interface.

[0010] The pulling and pushing elements are preferably tensile and compressive resistant and flexibly constructed in a single plane. For example, the pulling and pushing elements can be constructed in the form of chains or belts. Thus, the pulling and pushing elements can be housed in the housing containing the actuator with the least amount of space required, resulting in a compact overall structure of the drive unit. Here, the pulling and pushing elements are moved out of or into the housing to move the window or door.

[0011] Preferably, the electrical connection mechanism is constructed separately not only from the driver but also from the fixing structure. Therefore, the electrical connection mechanism can be easily disassembled for maintenance or replacement purposes.

[0012] The electrical connection mechanism, driver, and fixing structure are arranged in a space-saving manner such that the driver is arranged on one side of the fixing structure and the electrical connection mechanism is arranged on the side of the fixing structure opposite to the driver, with the fixing structure positioned between the driver and the connection mechanism.

[0013] To achieve a particularly simple construction of the driver, the driver's connecting wires can be reversibly and detachably connected to the electrical connection mechanism. Preferably, the connecting wires are mounted on the electrical connection mechanism using plug-in connectors, clamping connectors, or locking connectors. Using plug-in connectors, clamping connectors, or locking connectors enables simple assembly.

[0014] Similarly, the supply wire connecting the connection mechanism to the power supply and / or control unit can be reversibly and detachably connected to the electrical connection mechanism, for example, via a plug-in connector, clamping connector, or locking connector. In principle, the supply wire can also be connected to the electrical connection mechanism in other ways. For example, the supply wire can be fixedly brazed or screwed onto the electrical connection mechanism.

[0015] According to an advantageous design of the drive unit, the fixing structure can be constructed in the form of a bracket, comprising a first retaining element and a second retaining element. The retaining elements are used to house the drive unit within themselves. For this purpose, the retaining elements are preferably spaced apart from each other along the longitudinal extension of the drive unit. Preferably, the retaining elements are designed to be separate from each other such that the receiving area of ​​the fixing structure can be matched to the size of the drive unit. Preferably, the circuit board supporting the electrical connection mechanism can also be used to support the retaining elements of the bracket, specifically spaced apart from each other according to the size of the drive unit.

[0016] The drive interface of the connecting mechanism can be arranged on the first retaining element or the second retaining element. However, in principle, a separate drive interface can also be provided on each retaining element. This allows the driver to be fixed to the fixed structure in either a first orientation or a second orientation rotated 180°.

[0017] Sometimes, more than one actuator may be needed, for example, due to unfavorable leverage ratios or to move narrow, elongated, or heavy flaps or valves. To electrically connect multiple actuators, conventional drive systems stipulate that the actuators are connected to the power supply and / or control unit via corresponding connecting wires at a central junction box. This has proven problematic, as each actuator must be connected to the central junction box via its own connecting wire. An alternative solution involves forwarding current and / or signals to other actuators within the respective actuators. Here, the wiring is routed within the actuators, thereby increasing the structural cost of the actuators.

[0018] To avoid the aforementioned disadvantages, according to an advantageous design of the drive unit, it has an expansion interface electrically connected to the supply interface for electrical connection with another driver. Like the electrical connection mechanism, the expansion interface can be constructed separately from the driver. Here, the electrical wires connecting the expansion interface and the supply interface can also be constructed separately from the driver. The advantage of this is that the costly feedthrough of electrical wires inside the driver can be eliminated, thus allowing the driver to have a compact construction.

[0019] The expansion interface allows for modular expansion of the drive unit as needed, wherein the module includes a driver, an electrical connection mechanism as described herein, and a fixing structure as described herein.

[0020] Preferably, the electrical connection mechanisms of the two drives are interconnected via an extension wire, wherein one end of the extension wire is connected to the expansion interface of the connection mechanism of one drive and the other end of the extension wire is connected to the supply interface of the connection mechanism of the other drive. Furthermore, it can be specified that the two drives are electrically connected to each other via an extension wire such that the extension wire connects the expansion interface of one drive to the supply interface of the other drive.

[0021] The extension cable can be reversibly and detachably connected to the extension interface and / or supply interface, for example, by means of plug-in connectors, clamping connectors, or locking connectors. Alternatively, the extension cable can be fixedly soldered or screwed to at least one of the interfaces. According to a particularly simple design, the extension cable can be constructed as a cable, especially a flat ribbon cable.

[0022] According to an advantageous design of the drive device, the supply interface is arranged on the first retaining element, and the expansion interface is arranged on the second retaining element. This allows the drive device to be expanded in one direction. However, it is also possible to provide an expansion interface on each of the two retaining elements, thereby allowing the drive device to be expanded in both directions.

[0023] Preferably, the supply interface and the expansion interface are electrically connected to each other via connecting wires. The connecting wires can be constructed in the form of cables, particularly flat ribbon cables. This design is particularly advantageous in the case of long drives. In the case of short drives, the connecting wires can be constructed as wires integrated into a circuit board. The circuit board may also additionally have integrated wires that electrically connect the supply interface and the drive interface.

[0024] For ease of assembly, the drive unit may include a mounting plate that supports the fixed structure and the electrical connection mechanism. Thus, the fixed structure and the electrical connection mechanism can be pre-assembled onto the winglet or breech frame via the mounting plate. Subsequently, the drive unit can be easily fixed to the fixed structure.

[0025] A particularly advantageous design of the drive unit specifies that the fixing structure and electrical connection mechanism of the two drives are arranged on a common mounting plate.

[0026] The mounting plate can also form part of the housing of the drive unit. In particular, the mounting plate can be used as a cover for the wiring of the drive unit.

[0027] According to an advantageous design of the drive unit, a power supply unit for the driver is arranged on the fixed structure, particularly on one of the two retaining elements of the bracket. This allows, for example, a standardized 24V driver to operate at 230V. Alternatively, the power supply unit can also be arranged on the mounting plate. Attached Figure Description

[0036] The drive mechanisms shown in the accompanying drawings are used to move, by means of one or two actuators, the (not shown) flaps of a window or door relative to a fixed frame, also not shown. For this purpose, each of the actuators has flexible traction and actuation elements (not shown further), which may be designed in the form of chains or belts.

[0037] In order to convert the motion of the driver into the motion of the wing fan, the outer end of the pulling and pushing element is connected to the transmission mechanism 4, which is fixed to the wing fan when the driver is mounted on the breech frame or when the driver is mounted on the wing fan.

[0038] exist Figure 1a and 3a Each of the drive units shown includes a driver 6 with a cover plate and two end caps 8, which, when viewed in the longitudinal direction of the drive unit, form a closure of the drive unit at the opposite ends of the driver 6. For better illustration, in Figure 1b , 1c The detailed diagrams of 2b and 3b do not show one or more drivers or the cover plate.

[0039] Now for reference Figures 1a to 1c The construction of the drive device according to the first embodiment will be described in more detail.

[0040] For mechanical fixation to the wing or window frame, the drive unit includes a fixing structure 10. The fixing structure 10 also houses the drive unit and is constructed as a bracket for this purpose. The bracket 10 includes a first retaining element 12a and a second retaining element 12b separate from the first retaining element 12a. Figure 1c In the diagram, the first holding element 12a is schematically shown by a dashed line.

[0041] The retaining elements 12a and 12b are L-shaped and each has two legs 14 and 16. Specifically, each retaining element 12a and 12b has one fixed leg 14 and one retaining leg 16. The fixed leg 14 is used to secure the drive unit to the winglet or the frame. The retaining legs 16 are spaced apart from each other in the longitudinal extension of the drive unit and are used to secure the driver 6. The distance between the retaining legs 16 is oriented according to the size of the driver 6 and is sized such that the assembled driver 6 is accommodated between the retaining legs 16. Furthermore, the end cap 8 can be fitted onto the retaining legs 16, so that the drive unit has the aforementioned appearance in the assembled state.

[0042] To secure the drive unit to the wing fan or breech frame, a pair of first holes 18 are provided in the mounting legs 14, each for receiving a fixing element, such as a screw. The retaining legs 16 have a pair of second holes 20 through which fixing elements, such as screws, can be inserted or screwed to connect the drive unit 6 to the retaining elements 12a, 12b. Depending on the application, the retaining elements 12a, 12b may also have a smaller number of holes or additional holes for securing the drive unit 6.

[0043] An electrical connection mechanism 22, constructed separately from the bracket 10 and also separate from the drive 6, is arranged on the bracket 10. (If it can be seen from...) Figure 1a and 1b As can be seen from the overview, the electrical connection mechanism 22 is arranged on the side of the retaining elements 12a and 12b opposite to the side used to accommodate the driver 6. In other words, in the assembled state of the drive unit, the driver 6 is arranged on one side of the fixing structure 10, and the electrical connection mechanism 22 is arranged on the side of the fixing structure 10 opposite to the driver 6. Specifically, the electrical connection mechanism 22 is constructed on a circuit board 24, which is mounted on the side of the first retaining element 12a opposite to the driver 6.

[0044] Electrical connection mechanism 22 has supply interface 26 ( Figure 1c A supply wire 28 for electrically connecting the connection structure 22 to the power supply and / or control unit is connected to the supply interface. The supply wire 28 can be fixedly soldered, screwed, or mounted on the supply interface 26 via a plug connector, clamp connector, or locking connector.

[0045] Furthermore, the electrical connection mechanism 22 has a drive interface 30 that is electrically connected to the supply interface 26. Here, in the current embodiment, the drive interface 30 and the supply interface 26 are electrically connected to each other by means of wires integrated in the circuit board 24.

[0046] The drive interface 30 is used to connect the driver 6 to the electrical connection mechanism 22 via its connecting wires. The connecting wires of the driver and the drive interface 30 of the electrical connection mechanism 22 can be reversibly and detachably connected, for example by means of a plug-in connector, a clamping connector, or a locking connector. Thus, the connecting wires of the driver 6 can be easily disconnected from the electrical connection mechanism 22, thereby allowing the driver 6 to be easily disassembled.

[0047] As already mentioned, the electrical connection mechanism 22, having a supply interface 26 and a drive interface 30, is arranged on the first retaining element 12a. In addition to the drive interface 30 arranged on the first retaining element 12a, another drive interface 30 may also be provided on the second retaining element 12b to enable the driver 6 to be mounted in the first orientation or in the second orientation rotated 180°.

[0048] Furthermore, the drive unit has an expansion interface 32. The expansion interface 32 is used to expand the drive unit with additional drivers. For this purpose, the drivers 6 are interconnected via expansion wires 38, as follows: Figure 3a and Figure 3b As explained in more detail, the expansion interface 32 can also be used to electrically connect the drive unit to another drive unit. Here, the extension wire 38 connects the expansion interface 32 of one drive unit to the supply interface 26 of the other drive unit.

[0049] The expansion interface 32 is disposed on a circuit board 24' separate from the circuit board 24 of the connection structure 22. The circuit board 24' with the expansion interface 32 is arranged on the side of the bracket 10 away from the driver 6, more specifically on the second retaining element 12b.

[0050] The expansion interface 32 and the supply interface 26 are electrically connected via a connecting wire 34. In the drive device according to the first embodiment, the connecting wire 34 is designed in the form of a cable 34, more precisely, a flat ribbon cable 34. The flat ribbon cable 34 connects the circuit board 24 of the connection mechanism 22 to the circuit board 24' having the expansion interface 32. Here, at least one end of the cable 34 is reversibly and detachably connected to one of the circuit boards 24, 24', for example, via a plug-in connector, a clamping connector, or a locking connector. Furthermore, at least one end of the cable 34 can be fixedly connected to one of the circuit boards 24, 24', for example, by fixed soldering.

[0051] refer to Figure 2a and 2b The drive device according to the second embodiment is now described, which differs from the drive device according to the first embodiment in that the electrical connection mechanism 22 and the expansion interface 32 are arranged on a common circuit board 24". Here, the connecting wire 34 connecting the supply interface 26 and the expansion interface 32 is designed as a wire integrated into the circuit board 24". Furthermore, the common circuit board 24" supports the retaining elements 12a, 12b of the bracket 10, these retaining elements... Figure 2b It is schematically shown in the middle by dashed lines.

[0052] The drive unit in Figure 3a and 3b The third embodiment shown is based on the driving device in Figure 1b and 1c The first embodiment is shown. The drive device according to the third embodiment has two drivers, as can be seen by means of the two transmission mechanisms 4. However, the number of drivers 6 is not limited to two. Therefore, the drive device may also have more than two drivers.

[0053] For securing the drivers, a bracket 10 is provided, as described above in relation to the first embodiment of the drive device. In addition to the bracket 10, each driver 6 is provided with an electrical connection mechanism 22, which is connected to the expansion interface 32 in such a manner as described above in relation to the first embodiment of the drive device. In principle, the electrical connection mechanism 22 and the expansion interface 32 can also be connected to each other in such a manner as described above in relation to the second embodiment of the drive device.

[0054] Such as using Figure 3b As can be seen, the actuators 6 are electrically connected to each other via the previously mentioned extension wires 38. One end of the extension wire 38 is connected to an extension interface 32 disposed on the second retaining element 12b of the first bracket 10. The other end of the extension wire 38 is connected to a supply interface 26 disposed on the first retaining element 12a of the second electrical connection mechanism 22. At least one end of the extension wire 38 can be reversibly and detachably connected to one of the interfaces 26, 32, for example, via a plug-in connector, a clamping connector, or a locking connector. Alternatively or additionally, at least one end of the extension wire 38 can be fixedly connected to one of the interfaces 26, 32, for example, by fixed soldering.

[0055] Not only the bracket 10, but also the electrical connection mechanism 22 is supported by a common mounting plate 36. The mounting plate 36, together with the cover plate and the end cap 8, constitutes the housing of the drive unit.

[0056] Finally, it should be noted that the aforementioned drive devices may each have a power supply component, not shown in the accompanying drawings. This power supply component is configured to match the power supply voltage to the operating voltage of one or more drivers 6. This power supply component is preferably arranged on the fixing structure 10, and particularly on one of the retaining elements 12a, 12b of the bracket 10. However, the power supply component may also be arranged on the mounting plate 36. Furthermore, the power supply component may also be arranged on the circuit board 24.
