DETAILED DESCRIPTION OF THE DRAWINGS

[0110] The same parts are always provided with the same reference numerals in the different figures, which is why they are generally also only described once.

[0111] FIG. 1 shows a drive device 1 for pivoting a leaf 44 about a leaf axis F (FIG. 7a), in particular a door leaf or a window leaf. The drive device 1 has a motor-gear module 3. The motor-gear module 3 has a motor-gear housing 4, an electric machine 6 with a machine axis X1, and a gear 7 with an output shaft 8 mounted so as to be rotatable about an output axis X2 for connection to a lever 9.

[0112] The electric machine (6) is at least partially, in particular completely, arranged in an installation space between the leaf axis F and the output axis X2.

[0113] The drive device 1 also has a closer module 11 which has a closer housing 12 and a mechanical energy storage device 13.

[0114] The drive device 1 has an interface element for forming an operative connection between the motor-gear module 3 and the closer module 11.

[0115] The gear 7 has a transmission ratio as a quotient of the speed of the rotor as a dividend and the speed of the output shaft, with the transmission ratio being less than 125, preferably less than 100, particularly preferably less than 75.

[0116] The lever 9 is used to form a connection between the drive device 1 and the leaf 44, i.e. with the exemplary door leaf or window leaf or with a frame 48, with the drive device 1 being able to be mounted either on the frame 48 or on the leaf 44. Within the meaning of the disclosure, the term frame 48 also includes a door frame or window frame. In particular, the lever 9 can be designed in such manner that a voltage supply of the electric machine 6 and/or at least one control signal for the electric machine 6 can be transmitted via the lever 9 to the motor-gear module 3, in particular to the electric machine 6 and/or to a control module 26. The lever 9 is guided in a slide rail 2, which in the exemplary embodiment represented in FIGS. 1 and 2, would be mounted on a frame 48, not represented there, but which can be seen in FIG. 7a.

[0117] As can be clearly seen in FIGS. 1 and 2, the gear 7 is arranged in an installation space between the output axis X2 and the machine axis X1.

[0118] The motor-gear housing 4 has a first opening 16, with the closer housing 12 having a second opening 17. As can be seen in FIG. 1, the motor-gear housing 4 and the closer housing 12 are arranged in relation to one another in such manner that the closer module 11, in particular the energy storage device 13, and the gear 7, in particular the output shaft 8, are in operative connection with one another through the first opening 16 and the second opening 17 by means of the interface element.

[0119] The motor-gear housing 4 has a first side wall 51 facing the leaf axis F and a second side wall facing away from the leaf axis F. A reference numeral for the second side wall is not entered in FIG. 1 for reasons of clarity. However, the second side wall comprises the first opening 16 of the motor-gear housing 4. The electric machine 6 is at least partially, preferably completely, arranged in an installation space between the first side wall 51 and the output axis X2. The leaf axis F can be seen in FIGS. 1 and 2 as well as 4 and 5 and FIGS. 7a and 7b in the right-hand plane of the drawing.

[0120] The motor-gear module 3 and/or the closer module 11 is arranged at least partially, in particular completely, within a superordinate housing 5. The motor-gear housing 4 is connected to the superordinate housing 5 and/or to the closer housing 12 in a form-fitting and/or force-fitting and/or materially-bonded manner. The closer housing 12 is connected to the superordinate housing 5 in a form-fitting and/or force-fitting and/or materially-bonded manner. One or a plurality of such connections are designed, for example, in the form of at least one screw connection.

[0121] It can be seen in FIGS. 1 and 2 that the output axis X2 is parallel to the machine axis X1.

[0122] The closer module 11 has a transmission element 18 for translating a linear movement of the energy storage device 13 into a rotational movement of the transmission element 18 about an axis of rotation X3 of the transmission element 18. As can be seen by way of example in FIG. 1, the output axis X2 and the axis of rotation X3 of the transmission element 18 are spaced apart from one another and run parallel to one another. The transmission element 18 is designed as a cam disc, specifically as a heart-shaped stroke-producing cam disc, and is rotatably mounted in a rotationally-fixed manner with a closer wheel 10.

[0123] For example, the mechanical energy storage device 13 is designed as a compression spring. The compression spring is connected via a linkage carriage 27 to the transmission element 18 for translating the linear movement of the mechanical energy storage device 13 into a rotational movement of the transmission element 18. The linkage carriage 27 has sliding elements 21, which can be seen in FIG. 2. The linkage carriage 27 can be seen in FIG. 4.

[0124] The closer wheel 10 is arranged in a coaxial and rotationally-fixed manner in relation to the transmission element 18 for translating the linear movement of the energy storage device 13 into a rotational movement of the transmission element 18.

[0125] The gear 7 has an output wheel 22, in particular an output gear wheel, which is coaxial and rotationally-fixed with the output shaft 8, with the output wheel 22 being engaged with the closer wheel 10.

[0126] In the exemplary embodiment of FIGS. 1 and 2, the interface element is formed by the output wheel 22.

[0127] For example, the motor-gear housing 4 has a first wall 23 with an output opening 24 for the, in particular, rotationally-fixed connection of the output shaft 8 to the lever 9, a second wall adjoining the first wall 23 and a third wall opposite the second wall, with the drive device 1 being designed so as to be fastened both with the second wall and the third wall facing towards the leaf 44, i.e. the exemplary door leaf. The same can apply to the closer housing 12. The motor-gear housing 4, but also the closer housing 12, can each be cuboid in order to enable assembly on both sides.

[0128] The control module 26, which has a control device, can also be seen in FIG. 1. The control module 26 is arranged at least partially, in particular completely, within the superordinate housing 5 of the drive device 1.

[0129] FIG. 3 shows a special embodiment, with the transmission element 18 being formed as a cam disc, specifically as a heart-shaped stroke-producing cam disc. As can also be seen in FIG. 3, a fixed axle body 19 is arranged, with the transmission element 18 and the closer wheel 10 being rotatably mounted on the axle body 19.

[0130] In the FIGS. 4 and 5, the drive device 1 is represented in a further configuration, with the gear 7, in contrast to the exemplary embodiment of FIGS. 1 and 2, being designed as a planetary gear.

[0131] As a planetary gear, the gear 7 has a Wolfrom stage. Such a Wolfrom stage has a first gear stage and a second gear stage. The first gear stage comprises a sun gear, a plurality of first planets 32 fastened to a planetary carrier and driven by the sun gear, and a first, stationary ring gear. The sun gear, the planetary carrier and the first stationary ring gear cannot be seen in FIGS. 4 and 5 due to the view selected. The second gear stage comprises a second rotatable ring gear 33, second planets 31 which are rotationally-fixed with the first planets 32. The second planets 31 drive the second ring gear 33. The second ring gear 33 forms the power output of the planetary gear. In FIG. 5, the second ring gear is removed.

[0132] The gear 7 according to the exemplary embodiment of FIGS. 4 and 5 is designed as a combination of planetary gear and spur gear. The second ring gear 33 of the planetary gear has external teeth 34 and acts as a spur gear. The second ring gear 33 is engaged with the closer wheel 10 of the closer module 11. In the exemplary embodiment of FIGS. 4 and 5, the closer wheel 10 forms the interface element.

[0133] In the exemplary embodiment of FIGS. 4 and 5, the output axis X2 is coaxial with the machine axis X1.

[0134] In the exemplary embodiments described, the electric machine 6 is designed as an axial flux machine.

[0135] The electric machine 6 is represented in principle as a detail in FIG. 6. The electric machine 6 has a stator 36 and a rotor 37. The stator 36 has a plate-shaped stator base 38 and a plurality of stator teeth 39 protruding from the stator base 38 in the axial direction of the electric machine 6. A coil 41 is arranged around each of the stator teeth 39. Each stator tooth 39 has an electrically insulating tooth cover 75, with the stator 36 having a plurality of coils 41 and each of the coils 41 being wound around the tooth cover 75 and therefore indirectly via the tooth cover 75 around the stator tooth 39. The stator teeth 39 pass through a circuit board 74 on which the coils 41 are contacted.

[0136] It can be seen in FIG. 6 that the stator 36 also comprises a stationary bolt 50, with the bolt 50 having a bearing mount 76 for receiving a roller bearing 77. A roller bearing 77 with balls 77′ is represented in FIG. 6 as an example. The drive device 1 comprises the roller bearing 77 for the rotatable bearing of the rotor 37 with respect to the stator 36, with the roller bearing 77 being received on the bearing mount 76 of the bolt 50. The rotor 37 is rotatably mounted on the stator 36 by means of the roller bearing 77. In an embodiment that is not represented, a bearing mount can be provided directly on the stator base, on which a roller bearing can be received. The rotor 37 comprises a plurality of permanent magnets 78. Each permanent magnet 78 is formed in a plate shape. The rotor 37 has a rotor plate 79 in the form of a rotor disc. Furthermore, each permanent magnet 78 protrudes from the rotor plate 79 of the rotor 37 in the axial direction of the electric machine, in particular in the direction of the stator 36.

[0137] As can best be seen from FIGS. 1 and 2, the gear 7 has a first gear element 42 which can be rotated coaxially with the machine axis X1 and which is connected to the rotor 37 in a rotationally-fixed manner. The gear 7 also has a second gear element 43, which is operatively connected to the first gear element 42, with an axis of rotation X4 of the second gear element 43 running in an installation space between the machine axis X1 and an outer lateral surface of the rotor 37 that is extended virtually in the axial direction of the electric machine 6 or an outer lateral surface of the stator 36 that is extended virtually in the axial direction of the electric machine 6, in particular parallel to the machine axis X1.

[0138] In the exemplary embodiment of FIGS. 4 and 5, the first gear element 42 is formed by the sun gear, with the second gear element 43 being formed by the planet 32.

[0139] FIGS. 7a and 7b show a swing leaf arrangement 50 with the leaf 44, in particular a door leaf or a window leaf, which can be pivoted between a closed position 46 and an open position 47.

[0140] The closed position 46 of the leaf 44 can be seen in FIG. 7a. The open position 47 and an exemplary opening angle α of the leaf 44 can be seen in FIG. 7b. It can also be seen in FIG. 7a that the drive device 1 is mounted on the frame 48 with its slide rail 2. The drive device 1 is mounted on the leaf 44. A door handle 49 on the leaf 44 is also indicated in FIG. 7a. The leaf axis F is represented only schematically in FIGS. 1, 2 and 4 and 5 in order to make it clear that it is arranged in the plane of the drawing to the right of the machine axis X1.

[0141] The leaf 44 has a secondary closing edge 53 facing the leaf axis F and a main closing edge 54 opposite the secondary closing edge 53. The leaf 44 can be mounted on the secondary closing edge 53 by means of a hinge 56 so as to be rotatable about the leaf axis F. The swing leaf arrangement 50 can be pivoted with one of the drive devices 1 described above in their various configurations. It can be inferred from FIGS. 7a and 7b in connection with FIG. 1 that the electric machine 6, which is covered by the superordinate housing 5, is at least partially, in particular completely, arranged in an installation space between the leaf axis F and the output axis X2.

[0142] The electric machine 6 is therefore closer to the leaf axis F than the output shaft 5 such that in combination with the gear 7 this results in favorable transmission ratios from the electric machine 6 to the output shaft 8. Furthermore, such a drive device can be brought into operative connection with the mechanical energy storage device 13 of the closer module 11 in a simple manner, since, due to the machine position of the electric machine 6, the output shaft 8 faces the main closing edge 54 of the leaf 44. This also results in favorable transmission ratios from a closer module 11 to the output shaft 8 being achieved.
