Description

The invention relates to a door drive, in particular with a drive unit. Such a door drive is particularly suitable for sliding doors.

Drive units for door drives are known from the prior art. These are assembled from individual components, with the individual components being screwed onto a common carrier profile. The components are, for example, the drive motor, gearbox, power supply unit or controller. All these components are mounted side by side on the carrier profile and wired together.

It is disadvantageous in such a drive unit that by the arrangement of the components side by side a lot of space between the components remains unused. It is also disadvantageous that the individual components can not be flexibly arranged.

It is therefore an object of the invention to provide a door drive, which has a simple and cost-effective production and assembly safe and reliable operation, with a flexible structure is given.

The object is solved by the features of claim 1. Thus, the object is achieved by a door drive with a drive unit, wherein the drive unit comprises a first module, a second module and a third module. In this case, the first module on a motor and an output. The motor is in particular an electric motor and the output is in particular connectable with transmission elements to move door leaves. The output is in a preferred embodiment part of the engine, alternatively, output and motor are separate elements. The second module has a control unit for controlling the motor and the third module has a carrier element for receiving at least the motor and / or the output and / or the control unit. Furthermore, it is provided according to the invention that the drive unit has at least a first plane, a second plane arranged above the first plane and a third plane arranged above the second plane. The planes are preferably arranged in parallel and advantageously directly adjoin one another. A thickness of the planes is preferably freely selectable. Thus, the levels represent in particular individual areas of the drive unit. Within the levels of the assemblies are mounted, it being provided that within each level at least one assembly is arranged. Thus, it is also provided in particular that an assembly is arranged in several levels.

The dependent claims have preferred developments of the invention to the content.

It is preferably provided that a fourth level is arranged above the third level. In addition, the drive unit as a fourth module on a transmission. The transmission combines the engine and the output. Thus, a translation between the engine and output can be realized.

Particularly preferably, it is provided that a fifth plane is arranged above the fourth plane. Furthermore, it is particularly preferred that the drive unit comprises a printed circuit board as the fifth module. On the printed circuit board in particular sensors and / or control elements are arranged, which are assigned to the engine. Thus, in particular magnetic field sensors and / or at least one power electronics are arranged on the printed circuit board.

In particular, the drive unit is configured such that the transmission is arranged in the fourth plane, the motor and the output in the third plane, the carrier element in the second plane, and the control unit in the first plane. This allows a separate arrangement of mechanics and electronics, since the control unit on one side of the support member, the engine, the output and the transmission are arranged on the other side of the support member. In addition, such an arrangement allows no motor shaft to be needed. The torque generated by the engine can be transmitted directly through the rotor bell on the transmission and thus on the output.

Alternatively, the drive unit is in particular designed such that the transmission is arranged in the fourth plane, the engine and the output in the third plane, the control unit in the second plane, and the carrier element in the first plane. In this structure, the control unit is disposed directly below the engine. Thus, short transmission paths for controlling the motor by the control unit are available.

Particularly preferably, the control unit comprises a first control module and a second control module. The first control module is in particular via a plug connection with the second control module connected. Furthermore, it is preferably provided that the first control module in the first plane or in the second plane and the second control module in the second plane or in the third plane are arranged. Thus, the control unit is separated into two control modules. In particular, the separation of the control unit makes it possible to spatially separate a logic control from the motor control by arranging the logic control on the second control module, while the motor control is arranged on the first control module. This is advantageous because the motor control requires large electrical power. In contrast, the logic controller requires little electrical power. A spatial separation in the first control module and the second control module is therefore useful from the perspective of the design for the different services. In addition, it is preferably provided that the second control module has operating elements. Due to the arrangement of the second control module in the second level or third level, the first level and / or the second level are thus available for operating elements. Thus, there is enough space for the controls. As an alternative or in addition to the operating elements, it is also provided that the second control module has connecting elements.

Alternatively or additionally, it is preferably provided that a first part of the carrier element extend in the first plane or in the second plane and a second part of the carrier element in the second plane or in the third plane. Thus, only a single controller, namely the control unit, is present. Since the control unit extends in one plane, but the carrier element in several levels, the control unit is advantageously inserted through the carrier element. Thus, on the one hand a distance between the control unit and the engine is low, which in particular Magnetic sensors magnets of the engine can optimally capture, so that a high-quality position signal of a rotor of the motor can be detected. Therefore, the motor is very accurately controlled. This arrangement is achieved in that the first part of the carrier element extends in the first plane or in the second plane. Due to the fact that the second part of the carrier element runs in the third plane or in the fourth plane, sufficient space is provided for the control unit extending in the second plane in order to mount operating elements and / or connecting elements.

In a further alternative, the drive unit is configured such that the engine and the output are arranged in the fourth plane, the carrier element in the third plane, the control unit in the second plane, and the transmission in the first plane. In this structure, the engine and the output of the transmission by the support member and the control unit are spatially separated. Because of this separation, a motor shaft is preferably provided, with which the transmission is connected to the engine. Preferably, an output shaft is also provided, connect the transmission and output.

Finally, a further alternative is that the engine and the output are arranged in the fourth plane, the control unit in the third plane, the carrier element in the second plane, and the transmission in the first plane. This combines the aforementioned features and advantages of the spatial separation of the transmission from the engine and the output as well as the advantages of the direct arrangement of the control unit on the engine.

In a preferred embodiment of the invention there is a fifth level, as already described above. In this case, the Drive unit preferably formed such that the motor and the output in the fifth plane, the circuit board in the fourth plane, the support member in the third plane, and the control unit in the second plane, the transmission is arranged in the first plane. In addition to the aforementioned features and advantages of the spatial separation of the transmission from the engine and the output, it is advantageous here that magnetic sensors, in particular, can be arranged on the printed circuit board. With these magnetic sensors, a position of a rotor of the motor is preferably determined.

Alternatively, the drive unit is preferably configured such that the transmission is arranged in the fifth plane, the motor and the output in the fourth plane, the circuit board in the third plane, the carrier element in the second plane, and the control unit in the first plane. This in turn has the advantage that the carrier element separates mechanics and electronics. Thus, the control unit is arranged on one side of the carrier element, while the engine, the output and the transmission are arranged on the other side of the carrier element. The additional printed circuit board is arranged directly on the motor and is preferably equipped with magnetic sensors. Therefore, the circuit board additionally allows the aforementioned advantages of accurate position detection of a rotor of the motor.

In an advantageous embodiment, the drive unit has a power supply unit. The power supply is preferably arranged within at least one of the planes, in particular in a plurality of planes, particularly preferably in all planes. The power supply is preferably configured to supply the components of the drive unit with electrical energy. In addition, the drive unit preferably has a locking unit, wherein the locking unit is arranged within at least one of the planes. Particularly preferably, the locking unit is arranged within the same plane as the first assembly and / or the fourth assembly. The locking unit acts in particular on the first assembly, ie on the engine and / or the output, and / or on the fourth assembly, ie on the transmission, a. An action of the locking unit advantageously causes a blocking of at least the output, so that a movement of connected to the output door leaves is prevented.

The carrier element of the drive unit is preferably a housing of the drive unit. It is provided in particular that the housing surrounds the modules at least partially.

a schematic view of an eighth alternative of the drive unit of the door drive according to the embodiment of the invention,

The Fig. 1 shows a door drive 1 according to an embodiment of the invention. The door drive 1 comprises a drive unit 2 (see FIG. 2 ), for driving door leaves, not shown. The door leaves are in particular by a belt 20 (see. FIG. 2 ), wherein the belt 20 is driven by an output 8 of the drive unit. The output 8 is connected to a motor 7 via a transmission, wherein the transmission comprises a first gear element 11 and a second gear element 12. In particular, the first transmission element 11 is connected to the engine 7 and the second transmission element 12 to the output. The first transmission element 11 and the second transmission element 12 are preferably gears, so that the transmission is a gear transmission. Likewise, other types of transmissions are possible, such as belt transmissions or chain transmissions.

The motor 7 has a first axis 23, while the output has a second axis 24. The first axis 23 is preferably parallel to the second axis 24. Both the first axis 23 and the second axis 24 are fixed and anchored in a carrier element 10. The carrier element 10 therefore serves to hold the motor 7 and output 8. Also on the carrier element 10, a control unit 9 is attached. The control unit 9 serves on the one hand to control the motor 7, on the other hand a logic control in the control unit 9 is realized.

The power supply of the drive unit 2 is ensured by a power supply 22. The power supply 22 is preferably connectable to an external source of electrical energy and configured to convert the externally supplied energy into a size suitable for the control unit 9 and / or the motor 7.

Finally, a locking unit 21 is provided. The locking unit 21 acts on the belt 20 and / or on the output 8 and / or on the second transmission element 12 and serves for selectively blocking the belt 20 and / or the output 8 and / or the second transmission element 12. In this way is a lockable with the belt 20 door.

FIG. 2 shows an exploded view of the drive unit 2 of the door drive 1 from FIG. 1 , In this case, the power supply 22 and the locking unit 21 are not shown for clarity.

The logical structure of the drive unit 2 divides the components into different modules. Thus, a first assembly 3 is present, in which the engine 7 and the output 8 are arranged. In addition, the belt 20 is arranged in the first assembly 3, but this is only intended to illustrate the output 8. A second module 4 has the control unit 9. A third subassembly 5 comprises the carrier element 10, while a fourth subassembly 6 comprises the gear, that is, the first gear element 11 and the second gear element 12.

Furthermore, the logical structure of the drive unit 2 comprises different levels 100, 200, 300, 400, 500, as in the following FIGS. 3 to 10 is shown. In this case, the various assemblies 3, 4, 5, 6 in the various levels 100, 200, 300, 400, 500 can be arranged in different ways.

FIG. 3 shows a first alternative of the arrangement. The drive unit 2 comprises the in FIG. 2 shown components in FIG. 3 are provided with the same reference numerals as in FIG. 2 , Additionally points the drive unit 2 has a first level 100, a second level 200 arranged above the first level 100, a third level 300 arranged above the second level 200, and a fourth level 400 arranged above the third level. The first plane 100, the second plane 200, the third plane 300, and the fourth plane 400 are merely virtual planes in the structure of the drive unit 2.

In the in FIG. 3 As shown in the first alternative 100, the second module 4 with the control unit 9 is arranged in the first plane 100, and the third module 5 with the carrier element 10 is arranged in the second plane 200. In the third level, the first assembly 3 with the motor 7 and the output 8 is arranged, while in the fourth level 400, the fourth assembly 6 with the first gear member 11 and the second gear member 12 is arranged.

In the FIG. 3 The first alternative shown has the advantage that the control unit 9 is separated by the carrier element 10 from the motor 7, the output 8 and the first gear element 11 and the second gear element 12. This means that the mechanical structure is separated from the electrical structure.

FIG. 4 shows a second alternative of the arrangement of the drive unit 2. Again, all in FIG. 2 shown components present in FIG. 4 have the same reference numerals as in FIG. 2 , In the second alternative, this is the third assembly 5 and thus the carrier element 10 is arranged in the first plane 100. In the second level 200, the second assembly 4 is attached to the control unit 9. The first assembly 3 with motor 7 and output 8 is, analogous to the first alternative, arranged in the third plane 300, while in the fourth level 400, the fourth assembly 4 with first gear member 11 and second gear member 12 is mounted.

The second alternative has the advantage that the control unit 9 is arranged directly on the motor 7. In particular, the control unit 9 is arranged under the motor 7. Since the motor 7 has a rotor whose position is to be detected by magnetic sensors of the control unit 9, an accurate position signal can be detected by the direct arrangement of the control unit 9 on the motor 7.

FIG. 5 shows a third alternative of the arrangement of the drive unit 2. Again, all in FIG. 2 shown components present in FIG. 5 have the same reference numerals as in FIG. 2 , In the third alternative, the fourth subassembly 6 with the first gear element 11 and the second gear element 12 is arranged in the first plane 100. The second module 4 with the control unit 9 is arranged in the second plane 200, the third module 5 with the carrier element 10 is arranged in the third plane 300 and the first module 3 with the motor 7 and the output 8 is in the fourth plane 400 arranged.

In the third alternative, the first gear element 11 is connected via a shaft to the motor 7, while the second gear element 12 is also connected via a shaft to the output 8. The advantage of this alternative is that the transmission with the first gear element 11 and the second gear element 12 are spatially separated by the support member 10 of the motor 7 and the output 8.

FIG. 6 shows a fourth alternative of the arrangement of the drive unit 2. Again, all in FIG. 2 shown components present in FIG. 6 have the same reference numerals as in FIG. 2 , The fourth alternative differs from the third alternative only in that the second subassembly with the control unit 9 is arranged in the third plane 300, while the third subassembly 5 with the carrier element 10 is arranged in the second plane 200. This in turn has the advantage that the control unit 9 is arranged directly on the motor 7, whereby high-quality position signals for detecting a rotor of the motor 7 are present.

FIG. 7 shows a fifth alternative of the arrangement of the drive unit 2. Again, all in FIG. 2 shown components present in FIG. 7 have the same reference numerals as in FIG. 2 , In addition, the drive unit 2 has a fifth module 13 with a printed circuit board 14. The printed circuit board 14 comprises position sensors of a rotor of the motor 7, so that individual sensors are transferred from the control unit 9 to the printed circuit board 14. In addition, a fifth level 500 is disposed above the fourth level 400.

The fifth alternative is an extension of the third alternative, which in FIG. 5 is shown. Therefore, the assignment of the second assembly 4, the third assembly 5 and the fourth assembly 6 to the second level 200, the third level 300 and the first level 100 is analogous to the third alternative. In contrast to the third alternative, the first assembly 3 with the motor 7 and the output 8 is not arranged in the fourth plane 400 but in the fifth plane 500. In the fourth level 400, the fifth assembly 13 with the printed circuit board 14 is instead arranged. Thus, the circuit board 13 is directly on the motor. 7 arranged, resulting in the aforementioned advantages of the position detection of a rotor of the motor 7.

FIG. 8 shows a sixth alternative of the arrangement of the drive unit 2. Again, all in FIG. 2 shown components present in FIG. 8 have the same reference numerals as in FIG. 2 , Again, the drive unit 2 detects the previously described printed circuit board 14 and the fifth level 500. The sixth alternative is an extension of the first alternative, which in FIG. 3 is shown.

In the sixth alternative, the second module 4 with the control unit 9 in the first plane 100 and the third module 5 with the carrier element 10 in the second plane 200 are arranged. In the third level 300, the fifth assembly 13 is attached to the circuit board 14. Since in the fourth level 400 of the motor 7 and the output 8, that is, the first assembly 3, mounted, in turn, the aforementioned advantages of the direct attachment of the printed circuit board 13 to the motor 7. In the fifth level 500 is finally the fourth assembly 6 with first gear element 11 and second gear element 12 is arranged.

FIG. 9 shows a seventh alternative to the arrangement of the drive unit 2. Again, all in FIG. 2 shown components present in FIG. 9 have the same reference numerals as in FIG. 2 , In this alternative, the control unit 9 is divided into two and has a first control module 17 and a second control module 18. The first control module 17 and the second control module 18 are connected to one another via a plug connection 19. Due to the division of the control unit 9, this is arranged in several levels. So the first control module 18 is in the first level 100 while the second control module 19 is in the third level 300.

In addition to the control unit 9 and the support member 10 is mounted in two planes. Thus, a first part 15 of the carrier element 10 in the second plane 200 and a second part 16 of the carrier element 10 in the third plane 300 is arranged. This ensures that the entire control unit 9 is held by the carrier element 10.

The second subassembly 4 with the control unit 9 is therefore mounted both in the first plane 100 and in the third plane 300, while the third subassembly 5 with the carrier element 10 is mounted both in the second plane 200 and in the third plane 300. In the third level 300, the first assembly 3 with the motor 7 and the output 8 is also attached. The fourth assembly 6 with the first transmission element 11 and the second transmission element 12 is arranged in the fourth plane 400.

The construction of the seventh alternative advantageously allows the space-saving attachment of controls. Since the second control module 18 is arranged in the third level 300, the space below the control module 18 in the second level 200 and the first level 100 remains free. This space is thus available for the attachment of controls.

FIG. 10 shows an eighth alternative of the arrangement of the drive unit 2. Again, all in FIG. 2 shown components present in FIG. 10 have the same reference numerals as in FIG. 2 , In this alternative, the carrier element 10 is arranged in several planes. Thus, the first part 15 of the carrier element 10 in the first plane 100th arranged while the second part 16 of the support member 10 in the third plane 300 is arranged. Thus, the third assembly is mounted in both the first level 100 and the third level 300. In the third level 300, the first assembly 3 with the motor 7 and the output 8 is arranged in addition to the third assembly 5. In the fourth level 400, in turn, the fourth assembly 6 with the first gear element 11 and the second gear element 12 is arranged.

In order to arrange the control unit 9 in the second level 200, the carrier element 10 has a cutout at the location of the second level 200. Through this section, the control unit 9 can be pushed through. Thus, on the one hand, the previously mentioned advantage of the immediate arrangement of at least one part of the control unit 9 on the motor 7 and, on the other hand, the above-mentioned advantage of providing space for operating elements results in the first plane 100 below the second part 16 of the carrier element 10 free space for the controls is available.

As can be seen from the aforementioned alternatives, the door drive 1 is very flexible buildable. This allows optimal adaptation to a wide variety of applications, so that the door drive 1 is also very flexible.

In the FIG. 1 shown locking unit 21 and the power supply 22 also shown are advantageously arranged such that they extend over several levels. Thus, the power supply 22 preferably extends over all levels, that is to say via the first level 100, the second level 200, the third level 300, the fourth level 400 and, if the fifth level 500 is present, also via the fifth level 500 Locking unit 21 preferably extends at least over the third level 300 and the fourth Level 400 or alternatively via the fourth level 400 and the fifth level 500. Likewise, alternative courses over the levels are conceivable.
