Description

The invention relates to a closer module for moving a leaf, in particular a door leaf or a window leaf, with the features of the preamble of claim 1. The invention also relates to a drive device for moving a leaf, in particular a door leaf or a window leaf.

Closer modules and drive devices can be used to move a wing, a wing being understood in particular as a door or window wing. The movable part of a door is referred to as a door leaf, for which the term door leaf is also common.

Such closer modules and drive devices are known. Such closer modules and drive devices are typically provided directly on the leaf to be moved or on a door frame or a window frame. The space available is very limited, particularly when mounting on the door frame or the window frame.

Against this background, the task is to enable a compact configuration of a closer module and/or a drive device.

The task is solved by a closer module with the features of claim 1 . However, the object is also achieved by a drive device having the features of claim 7 . Advantageous developments of the drive device are specified in the dependent claims, the description and in the figures. Features and details that are described in connection with the drive device according to the invention also apply in connection with the method according to the invention and/or the use according to the invention and vice versa. The features mentioned in the description and in the claims can each be essential to the invention individually or in combination. The description additionally characterizes and specifies the invention, in particular in connection with the figures.

A closer module for moving a leaf, in particular a door leaf or a window leaf, is particularly advantageously specified. The closer module has a mechanical energy store, a rotatable transmission element for converting a linear movement of the energy store into a rotary movement of the transmission element about an axis of rotation of the transmission element and a rotatable closer wheel, in particular closer toothed wheel, arranged coaxially with the transmission element. The closer module has a fixed axle body, with the transmission element and the closer wheel being rotatably mounted on the axle body.

This configuration saves space in the axial direction, since bearings can be arranged surrounded by the transmission element and/or by the closer gear wheel. The axle body is not rotatable.

In particular, the transmission element can be designed as a cam disk. In particular, the cam disc can be embodied symmetrically or asymmetrically. Furthermore, the cam can be designed as a lifting cam, in particular heart-shaped.

In particular, the mechanical energy store can have one or more compression springs and/or tension springs, which are connected to a link carriage. The plate carriage serves to form an operative connection between the transmission element and the mechanical energy store of the closer module.

It can be preferred that the transmission element and the closer wheel are non-positively and/or positively and/or cohesively connected to one another in a torque-proof manner or are formed in one piece.

It can be preferred that the transmission element and the closer wheel are each mounted individually or together on the axle body.

It may be preferable for the transmission element and/or the closer wheel to be rotatably mounted on the axle body individually or jointly by means of at least one pivot bearing, preferably a roller bearing or a sliding bearing, in particular a needle bearing or a ball bearing.

It can be preferred that the sliding element is plate-shaped. It can be particularly preferred that in particular each sliding element is movably arranged in a sliding guide of the closer housing.

This configuration is advantageous with regard to the linear guidance of the link carriage and the absorption of the linear forces transverse to the running direction of the link carriage.

The closer housing can be made in one piece or in several pieces. In particular, the closer housing can have a bottom wall and/or two end walls, it being possible for the link plate carriage to be guided linearly on the bottom wall and/or on one end wall or on both end walls. In particular, the end walls of the closer housing can run parallel to the leaf in its closed position. In particular, the sliding elements can be arranged parallel to the end walls.

In particular, the sliding elements can be designed as skids. In particular, the sliding element and/or the sliding guide can be coated at least on the respective contact surfaces, in particular coated by means of a friction-reducing coating.

In particular, the sliding element or the sliding elements and the link carriage can be connected in a form-fitting and/or force-fitting and/or cohesive manner, particularly preferably in one piece.

A drive device for moving a leaf, in particular a door leaf or a window leaf, is particularly advantageously specified. The drive device has a motor-transmission module, which includes an electric machine with a machine axis, a transmission with an output shaft that is rotatably mounted about an output axis for connection to a lever. The drive device has the closer module, with a motor-gear module and the closer module being operatively connected.

The lever serves to form a connection between the drive device and the wing or with a frame, the drive device being mountable on the frame or on the wing. Within the meaning of the invention, the term frame also includes a door frame or window frame. In particular, the lever can be designed in such a way that a voltage supply for the electric machine and/or at least one control signal for the electric machine can be transmitted via the lever to the motor-gearbox module, in particular to the electric machine.

The machine axis means the axis of rotation about which a rotor of the electrical machine rotates.

The electrical machine can be designed as a motor and/or generator. As a motor, the machine can generate a rotary movement, in particular a torque, from electrical energy. As a generator, the machine can generate electrical energy from a rotational movement, in particular from a torque.

In particular, the motor-gearbox module can be arranged at least partially, in particular completely, within a motor-gearbox housing. In particular, the closer module can be arranged at least partially, in particular completely, within a closer housing.

In particular, the motor-gear module and/or the closer module can be arranged at least partially, in particular completely, within a superordinate housing. In particular, the motor-transmission housing can be connected to the superordinate housing in a non-positive and/or positive and/or material connection. In particular, the closer housing can be connected to the superordinate housing in a force-fitting and/or positive and/or material-locking manner. In particular, one or more such connections can be implemented in the form of at least one screw connection and/or a pin connection and/or a press fit and/or a T-groove and/or a snap connection. In particular, the motor-transmission housing can be connected to the closer housing in a non-positive and/or positive and/or material connection, preferably by means of at least one screw connection and/or a pin connection and/or a press fit and/or a T-slot and/or a snap connection.

In particular, the electrical machine and/or the transmission can be arranged at least partially, in particular completely, within the motor/transmission housing. This does not include connecting cables to and from the electrical machine. In particular, the mechanical energy store can be arranged at least partially, in particular completely, within the closer housing.

In particular, the drive device can have a control module with a control device. In particular, the control module can be arranged at least partially, in particular completely, within the superordinate housing of the drive device.

In particular, the control module can be arranged on the closer module or inside the motor/gearbox housing.

In particular, the control module can include a control housing. In particular, the control module can be arranged entirely within the control housing. In particular, the control housing can be connected to the superordinate housing and/or to the motor-gear housing and/or to the closer housing in a non-positive and/or positive and/or material connection. In particular, one or more such connections can be implemented in the form of at least one screw connection and/or a pin connection and/or a press fit and/or a T-groove and/or a snap connection.

In particular, the motor/gearbox housing and/or the closer housing and/or the control housing can be arranged within the superordinate housing. The terms superordinate housing and superordinate cladding are used synonymously in the following.

The wording - inside the housing - means that the elements are arranged at least partially, in particular completely, in the space formed by the housing.

In particular, the motor-transmission housing can have one or more prefabricated receiving points for a form-fitting and/or non-positive and/or material connection with the electrical machine and/or the transmission and/or the output shaft. In particular, the closer housing can have one or more prefabricated receiving points for a positive and/or non-positive and/or material connection with the closer wheel and/or the transmission element and/or the axle body and/or the link plate carriage.

In particular, the transmission can be arranged at least partially, in particular completely, in a space between the output axle and the machine axle, in particular a virtual extension of the machine axle. In particular, the electrical machine can be arranged at least partially, in particular completely, in an installation space between a vane axle and the output axle. Alternatively or cumulatively, the electrical machine can be arranged between a secondary closing edge of the wing, in particular a virtually extended one, and the output shaft. In this way, the desired torque and/or the desired speed can be transmitted from the electric machine to the output shaft via the transmission in a simple and/or space-saving manner.

The installation space has a width, a height and a depth, with the width being limited by a distance between the blade axis and the output shaft or gear. In particular, the height and/or the depth of the installation space can be limited by the motor/transmission housing or by the transmission or by the electric machine.

In particular, the leaf can have the secondary closing edge facing the leaf axis and a main closing edge opposite the secondary closing edge, with the main closing edge usually facing the door handle.

As a result, the electric machine is closer to the blade axis than the output shaft, so that in combination with a gearbox this results in favorable transmission ratios from the electric machine to the output shaft. Furthermore, such a drive device can be brought into operative connection with the mechanical energy store of the closer module in a simple manner, since the output shaft faces the main closing edge of the wing due to the position of the machine. In particular, favorable transmission ratios can also be realized from the closer module to the output shaft. A structure of this type also enables installation space to be saved in that the control device can be attached closer to the electrical machine.

The terms axle and vane axle and output axle mean virtual axles, in particular rotary axles, which are fundamentally not limited in their extent.

In particular, the vane axis and/or the output axis can have a substantially vertical course. In particular, the vertical component of the gradient can be 90 to 100, in particular 95, percent.

In particular, the motor-transmission module can comprise the motor-transmission housing with a first side wall facing the wing axis and a second side wall facing away from the wing axis. In particular, the electric machine can be arranged at least partially, preferably completely, in an installation space between the first side wall and the output shaft.

In particular, the machine axis and the output axis can run parallel, preferably on a virtual plane. Alternatively or cumulatively to the output axle, one or more in particular, all axes of rotation of the respective transmission elements also run parallel to the machine axis, preferably on the same virtual plane. Such an arrangement enables a reduction in friction losses.

In particular, the output shaft can be arranged in a space between the machine axis and the energy store. In this case, the installation space has a width, a height and a depth, the width being limited by a distance between the machine axis and the energy store. In particular, the height and/or the depth of the installation space can be limited by the motor/gearbox housing or by the gearbox or by the electric machine or by the energy store or by the closer housing.

It can be preferred that the drive device has an interface element for forming an operative connection between the motor-gear module and the closer module. It can be preferred that the interface element comprises at least one gear wheel. In particular, the interface element can have a plurality of gears.

In particular, the interface element can be operatively connected, in particular engaged, to the transmission and operatively connected to the energy store.

Torque can be transmitted from the output shaft to the closer module and/or from the closer module to the output shaft by means of the interface element.

The interface element can be formed by means of at least one transmission element of the transmission and/or by means of at least one element of the closer module and/or by an additional element. The interface element can be made in one piece or in several pieces.

It can be preferred that the output axis runs parallel or coaxially to the machine axis.

It can be preferred that the motor-gear module has the motor-gear housing and the closer module has the closer housing. It can be preferred that the motor/gearbox housing includes a first opening and the closer housing includes a second opening. It can be particularly preferred that the motor/gearbox housing and the closer housing are arranged relative to one another in such a way that the closer module, in particular the energy store, and the gearbox, in particular the output shaft, can be pushed through the first and second opening by means of the interface element interact with each other.

The walls of the respective housings, which comprise the first and the second opening, can be designed to be flat. This allows the motor-gear housing and the closer housing to be fitted flush to one another.

In particular, the interface element can protrude into the motor/gearbox housing and/or into the closer housing. In particular, the interface element can protrude into the space formed by the respective housing.

In particular, the closer module can include a closer wheel, in particular a closer gear wheel, with the closer wheel being arranged coaxially, preferably in a rotationally fixed manner, with respect to the transmission element. In particular, the transmission element and the closer wheel can be connected in a form-fitting and/or force-fitting and/or cohesive manner, in particular can be formed in one piece.

It can be preferred that the output axis and the axis of rotation of the transmission element run at a distance from one another, in particular parallel to one another. On the one hand, the output shaft and the transmission element therefore do not rotate about the same axis of rotation and can be arranged in different positions, in particular in a modular manner. On the other hand, the parallel run reduces energy losses and facilitates assembly. In particular, the transmission element can be designed as a cam disk. In particular, the cam disc can be embodied symmetrically or asymmetrically. Furthermore, the cam can be designed as a lifting cam, in particular heart-shaped.

It can be preferred that the interface element is at least partially formed by the closer wheel, in particular the closer gear wheel, or is in engagement with the closer wheel.

It can be preferred that the transmission has a driven wheel, in particular a driven gear wheel, which is coaxial with the driven shaft and is preferably non-rotatable.

In particular, the output wheel and the output shaft can be connected in a form-fitting and/or force-fitting and/or cohesive manner, preferably in one piece.

In particular, the driven wheel can be in engagement with the interface element or at least form part of the interface element.

In particular, the interface element can comprise a component, preferably a wheel, particularly preferably a gearwheel, with the component being in direct operative connection with the closer wheel and/or the driven wheel. In particular, the component can also be a belt, a chain or a cable.

In particular, the closer module can have the transmission element for converting a linear movement of the energy store into a rotational movement of the transmission element about an axis of rotation of the transmission element, with a transmission ratio of the transmission element to the output shaft in the range from 0.6 to 1.1, preferably in the range from 0.65 to 1.05, more preferably in the range from 0.7 to 1.0, especially 0.75 to 0.9.

The transmission ratio here means the quotient of a speed of the transmission element as a dividend and a speed of the output shaft or the quotient of a torque of the transmission element as a dividend and a torque of the output shaft.

In particular, the motor/gear housing or the closer housing can have a first wall with an output opening for the non-rotatable connection of the output shaft to the lever, a second wall adjoining the first wall and a third wall opposite the second wall. In particular, the drive device can be designed in such a way that it can be fastened with both the second wall and the third wall facing the wing.

In particular, the motor-gear housing and the closer housing can each be cuboid. In this case, the motor-gear housing and/or the closer housing can be cuboid, ie with four adjoining walls, with the adjoining walls being orthogonal to one another. In this way, the drive device can be mounted on both sides. _[JJ1]

In particular, the drive device can be mounted on a hinge side as well as on an opposite hinge side of the sash and/or both in the case of sashes rotating to the left and to the right. The drive device can thus be used more flexibly and can therefore be adapted to different installation conditions. For this purpose, the drive device can be designed symmetrically to a vertical plane running parallel to the closed wing. Furthermore, for this purpose the output shaft can be mounted rotatably in both directions of rotation from a neutral position. Furthermore, the output shaft can be designed to be connectable on both sides with a lever for connection to the wing with respect to its axial course. Furthermore, a fourth wall of the motor-gear housing opposite the first wall of the motor-gear housing can have a further output opening. As a result, both ends of the axial course of the output shaft can be connected in a rotationally fixed manner to a lever for connection to the vane. In particular, the lever can be designed as a scissor linkage.

It can be preferred that the transmission is designed as a toothed wheel transmission. In particular, the gear can be designed as a multi-stage spur gear and/or as a planetary gear or as an eccentric gear.

In particular, the gear can be designed as a combination of planetary gear and spur gear. A ring gear of the planetary gear can have external teeth and act as a spur gear, in particular with the ring gear being in engagement with the closer wheel of the closer module and/or the interface element and/or with the ring gear forming the interface element.

As a planetary gear, the gear can have a sun gear that is non-rotatable with the rotor, in particular one piece, several planet gears fastened around the sun gear on a planet carrier, and a ring gear that meshes with the planets. In this case, the ring gear can be rotatably mounted and form the power output of the planetary gear, with the planetary carrier being designed to be stationary. Alternatively, the planet carrier can be rotatably mounted and form the power output of the planetary gear, with the ring gear being designed to be stationary.

As a planetary gear, the gear can also have at least one tungsten stage. In a preferred embodiment of such a tungsten stage, the planetary gear has a first gear stage and a second gear stage, the first gear stage comprising a sun gear, a plurality of first planets attached to a planet carrier and driven by the sun gear, and a first stationary ring gear, and the second gear stage second rotatable ring gear, second planets which are non-rotatable with the first planets, in particular one-piece planets, wherein the second planets drive the second ring gear. In particular, the second ring gear can form the power output of the planetary gear.

As an eccentric gear, the gear can be designed as a planetary eccentric gear and/or strain wave gear.

In particular, the transmission can have a transmission ratio as a quotient of the speed of the rotor as a dividend and the speed of the output shaft, the transmission ratio being less than 125, preferably less than 100, particularly preferably less than 75.

By selecting the transmission ratio of the transmission, which is less than 125, preferably less than 100, particularly preferably less than 75, a compact design of the transmission is made possible, so that the drive device is compact overall, but friction is also reduced . The efficiency of the transmission is also significantly increased; because with small transmission ratios, energy losses are reduced.

In particular, the interface element can be in engagement with a gear wheel, in particular a ring gear, of the transmission. In particular, the gear wheel of the transmission can have external teeth. In particular, the external teeth can be operatively connected or engaged with the closer wheel. In particular, the closer wheel can be operatively connected or non-rotatably, in particular positively and/or non-positively and/or cohesively connected or formed in one piece with the transmission element.

In particular, the transmission can have a first transmission element that can be rotated coaxially with the machine axis. In particular, the first transmission element can be connected to the rotor in a torque-proof manner.

This refinement is advantageous in terms of saving installation space in the radial direction of the electrical machine.

In particular, the transmission can have a second transmission element, which is operatively connected to the first transmission element and that an axis of rotation of the second transmission element is located in a space between the machine axis and an outer lateral surface of the rotor that is virtually extended in the axial direction of the machine or a virtual one in the axial direction of the Machine extended outer surface of the stator, in particular parallel to the machine axis, runs.

This refinement is advantageous with regard to a further saving in installation space in the radial direction of the electrical machine.

In particular, the first transmission element can be arranged entirely in a space, the space being delimited by an outer jacket surface of the rotor that is virtually lengthened in the axial direction of the machine.

In particular, the first and the second transmission element or the entire transmission can be arranged completely in one installation space, the installation space being delimited by an outer lateral surface of the rotor that is virtually extended in the axial direction of the machine or by an outer lateral surface of the stator that is virtually extended in the axial direction of the machine will.

It can be preferred that the electrical machine is designed as an axial flow machine. It can be preferred that the axial flow machine has one, in particular a single, stator and a rotor, in particular a single, rotatable relative to the stator. It can be particularly preferred that the stator has one or more coils and the rotor has one or more permanent magnets.

In the axial flux machine, the magnetic flux is mainly formed parallel to the machine axis of the electrical machine. The axial flow machine has a small overall axial length compared to other machine types. The axial overall length means an overall length in a direction parallel to the machine axis. The use of an axial flow machine therefore enables the dimensions of the electrical machine to be reduced in the axial direction. This allows a compact configuration of the motor-gearbox module. In particular, the axial flow machine can be a brushless direct current machine, in particular a so-called BLDC machine. Such a machine is constructed like a three-phase synchronous machine with excitation by permanent magnets.

The axial flow machine can be designed as a motor and/or generator. As a motor, the axial flow machine can generate a rotational movement, in particular a torque, from electrical energy. As a generator, the axial flow machine can generate electrical energy from a rotary movement, in particular from a torque.

In particular, the stator for the axial flux machine for moving the sash, in particular a door sash or a window sash, can have a, in particular plate-shaped, stator base and a plurality of stator teeth protruding from a common surface of a base section, in particular in the axial direction of the axial flux machine. In particular, the stator base can have a bearing mount for accommodating a roller bearing or a plain bearing.

This configuration is advantageous with regard to a compact design in the axial direction.

The term coil means an electrical conductor with at least one winding. The electrical conductor can be embodied as an insulated wire and/or insulated strip, in particular by means of a coating, preferably by means of an insulating lacquer. For this purpose, the conductor can have an insulating coating, in particular an insulating varnish. In particular, the coil can be in the form of a cast coil, individual windings of the coil being electrically insulated from one another by means of a cast material.

In particular, the rotor can include at least one permanent magnet, with the permanent magnet being arranged along a virtual circle around the machine axis and spanning a first angular range. The stator can comprise the stator base with at least one stator tooth protruding from the stator base, in particular in the axial direction of the axial flux machine, the stator tooth being arranged along a virtual circle around the machine axis and spanning a second angular range. The ratio of the first angular range as a dividend to the second angular range is in the range from 1.1 to 1.6, preferably in the range from 1.2 to 1.5, particularly preferably in the range from 1.3 to 1.4. If there are several teeth and/or magnets, each tooth can have the above-mentioned ratio to each magnet. Alternatively or cumulatively, in the case of several magnets and teeth, a summed area, i.e. a ratio, can be in a range from 1.3 to 1.9 or even from 1.5 to 1.8.

For the purposes of the invention, the term circle around the machine axis means that the machine axis forms the center point of the circle.

In particular, a surface of the stator tooth running parallel to the stator base, in particular of each stator tooth, can be designed in such a way that the surface widens in the radial direction of the stator, starting from the machine axis. Alternatively or cumulatively, a surface of the permanent magnet running parallel to the stator base, in particular of each permanent magnet, can be designed in such a way that the surface widens in the radial direction of the rotor, starting from the machine axis. In this way, the specified ratio of the first angular range as a dividend to the second angular range can be kept constant along the radial course of the stator. In particular, the surface of the stator tooth running parallel to the stator base, in particular of each stator tooth, can remain constant along the axial course of the stator tooth.

In particular, a coil can be wound directly or indirectly around at least one of the stator teeth, in particular around each stator tooth. In particular, the stator teeth can protrude from a common surface of the stator base.

In particular, the stator base can be connected to at least one, in particular each, stator tooth in a form-fitting and/or force-fitting and/or cohesive manner or can be formed in one piece. In particular, the stator can have the stator base, which has a base section, in particular in the form of a plate, and a plurality of stator teeth protruding from a common surface of the base section, in particular in the axial direction of the machine.

In particular, at least one, in particular each, permanent magnet can be designed in the form of a plate. In particular, the rotor can have a rotor plate, in particular a rotor disk. Furthermore, at least one, in particular each, permanent magnet can protrude from the rotor plate of the rotor in the axial direction of the machine, in particular in the direction of the stator. In particular, the rotor plate can have one or more indentations, in particular a number of indentations corresponding to the number of permanent magnets, with a permanent magnet lying in each indentation. In particular, the shape of the indentation, in particular each indentation, can correspond to the shape of the inlaid permanent magnet. This serves to secure the permanent magnets on the rotor, particularly on the rotor plate.

In particular, the electrical machine, in particular as a motor, can have a ratio of the maximum torque to the axial extent of the machine that is greater than 30 Nm/m, preferably greater than 100 Nm/m, particularly preferably greater than 200 Nm/m. m. The axial extent is parallel to the machine axis. In particular, this ratio can be greater than 50 Nm/m, preferably greater than 70 Nm/m, particularly preferably greater than 150 Nm/m. In particular, the electric machine can have a torque density, i.e. torque to motor volume, of greater than or equal to 6000 Nm/m^3, preferably greater than or equal to 15000 Nm/m^3 and particularly preferably greater than or equal to 20000 Nm/m^3 and/or or have a torque constant of greater than or equal to 0.1 Nm/A, preferably greater than or equal to 0.2 Nm/A and particularly preferably greater than or equal to 0.3 Nm/A. This refinement enables a compact design of the transmission and such small transmission ratios, while still enabling the door to be closed reliably, with the drive device being of compact construction overall.

In particular, the electrical machine configured as an axial flux machine can have a ratio between the extent of at least one stator tooth in the axial direction of the electrical machine as a dividend and the extent of the stator base in the axial direction of the electrical machine, with the ratio being greater than or equal to 2, in particular greater than or equal to be equal to 3, in particular greater than or equal to 4, in particular greater than or equal to 5, in particular greater than or equal to 6.

In particular, the drive device can be used in a swing door drive.

In a rotary leaf drive, a leaf is pivoted from a closed position, in which the leaf rests against a frame or frame, to an open position about a leaf axis by means of the drive device, with the torque being transferred by means of a lever from the output shaft of the drive device to the door or to the door Frame is transferred. The drive device can be mounted on the wing, in which case a running rail can be arranged on the frame, or on the frame, in which case a running rail can be arranged on the wing. In addition to the drive device, the swing leaf drive can also include the lever and/or the running rail and/or the leaf. In particular when used on fire protection leaves, the drive device can have a closer module. In the event of a fire, the closer module ensures that the fire protection leaf closes, in particular without manual operation.
