An adjustment body connection device AV can also be realized by a connection device introduced in the adjustment body frame 11. In addition, the adjustment body connection device AV can be a section of the adjustment body frame 11 itself.
[0138] In an alternative embodiment of the adjustment device 1 which is alternative to the embodiments shown, it comprises only one drive device C and in this case only one adjustment body connection device AV.
[0139] Embodiments of the drive devices C which can be integrated in each of the embodiments of the adjustment device 1 according to the invention are described below. In the figures, the same reference numerals are used for each of the various drive devices C shown. In various embodiments of the drive devices C, the same reference numerals are used for features or components which comprises the same function.
[0140] The at least one drive device C comprises an electrical coil 71. The coil 71 comprises at least one conductor winding and preferably a plurality of conductor windings which completely surround or surround a coil axis AS of the coil 71. The coil axis AS may be defined as a geometric center of the coil 71 or may be identical in position and direction to the central curvature-free field line.
[0141] In this case, it can in particular be provided that the coil axis AS runs along the flexure hinge rotation axis D1.
[0142] At least one drive device C can also comprise a coil device 70 with a coil housing 72 which partially or entirely surrounds the coil axis AS and in which the coil 71 is structurally integrated and in particular situated or held. In particular, the coil housing 72 can be designed as a hollow-ring-shaped coil housing in which the coil 71 is arranged, wherein the circumferential direction of the coil 71 extends along the circumferential direction of the coil housing 72. The coil housing 72 can also be designed as a coil housing in the form of a hollow ring in sections, so that the coil housing is not circumferentially closed. In the design of the coil housing 72 as a coil housing in the form of a hollow ring in sections, the geometric axis of the respective hollow ring section of the coil housing 72 runs in or along the coil axis AS of the coil 71.
[0143] Each drive device C comprises a compensation component 80. In each of the embodiment s of the adjustment device 1 according to the invention, the coil 71 or the coil housing 72 and the compensation component 80 can be fixed to one another or fixed to one another directly or indirectly, that is to say via a structural component, and together form an actuator 60, since an electric magnetic field is generated when the coil 71 is energized.
[0144] The compensation component 80, as is realized in the embodiment of the actuator 60 according to
[0145] Alternatively, the actuator 60 can also be realized in such a way that the compensation component 80 is held and fixed on the coil 71 or the coil housing 72 by a single shaped piece, which can be, for example, a U-shaped shaped piece which engages around the coil 71 or the coil housing 72 and receives the compensation component 80 between leg sections. Further alternatives include the potting of the coil 71 and the compensation component 80 to form a unit, for example with epoxy resin casting compound, or the encapsulation of coil 71 and compensation component 80 with a plastic material.
[0146] The fastening or fixing of the compensation component 80 to the at least one fastening part 63, 64 can also take place by a different connection device than by at least one connecting element 65, such as, for example, a clip connection. The at least one fastening part 63, 64 can also be glued or soldered to the coil 71 or the coil housing 72, this realization being able to take place with or without a connecting element 65.
[0147] The compensation component 80 is preferably arranged outside a portion of the coil as seen in the coil axis AS. In particular, in each of the embodiments of the adjustment device, the arrangement of the compensation component can be provided according to one of the two alternatives: (K1) as seen in the coil axis AS, in the outer space surrounded by the inner circumference of the coil 71 or, in the case of an at least partially hollow-ring-shaped coil housing 72, in the outer space surrounded by the coil housing 72 (
[0148] An embodiment of the actuator 60 according to the realization alternative (K2) is illustrated in
[0149] The compensation component 80 comprises a magnetizable or a magnetized material or can be produced from a soft or hard magnetic material. Preferably, the compensation component 80 is formed as a homogeneous material block and at the same time or as an alternative. In each embodiment of the adjustment device 1, the compensation component 80 can be configured in different shapes relative to one another. In particular, the compensation component 80 can be substantially cuboid or cylindrical, For this purpose, alternatively or additionally, the compensation component 80 is elongate with different cross-sectional shapes. In an elongated shape, the compensation component 80 can comprise a cross-sectional area with a circular or elliptical or square shape, with the shape of a rectangle or generally in the form of a polygon. In the case of an elongated shape, the compensation component 80 can comprise a center line running in the longitudinal direction thereof, which runs along or in the direction of the distance between the adjustment body rotation axis D1 and the coil axis AS when this distance runs through the center Z.
[0150] The adjustment device 1 according to the invention comprises at least one permanent magnet segment MS, which is mounted movably relative to the coil 71 or to the coil housing 72, from a hard magnetic material. In the figures, the permanent magnet segment MS is shown as an one-piece or one-piece component, wherein a separation line T is introduced, which however can be a fictitious separating line, The reference sign T is entered in
[0151] In each embodiment of the adjustment device 1 according to the invention, the permanent magnet segment MS can be generally in particular plate-shaped or cuboid-shaped, but can also comprise any other spatial shape. In the case that the permanent magnet segment MS is plate-shaped, the permanent magnet segment MS extends in a direction which runs in or along the relative movement between the coil and the permanent magnet segment upon actuation of a respective drive device. Furthermore, the at least one permanent magnet segment MS comprises a surface defining the longitudinal extension thereof, the orientation of which is directed along or in the direction of the coil axis AS.
[0152] The mounting of the drive device C on the adjustment device 1 for carrying out the adjustment movement can be provided according to one of the two alternatives (a), (b): (a) the actuator 60 is coupled to the base component B1 and the permanent magnet segment (MS) is coupled to the adjustment body connection device AV (moving magnet principle), (b) the actuator 60 is coupled to the adjustment body connection device AV and the permanent magnet segment MS is coupled to the base component B1 (moving coil principle).
[0153] In the embodiments of the adjustment device 1 shown in
[0154] Optionally, the magnetic segment supports 53, 54 may be attached to each other. This fastening can be realized by means of at least one connecting piece. An example of this implementation is illustrated in the embodiment of the actuator 60 shown in
[0155] The magnetic segment support 53, 54 is preferably formed from a soft magnetic steel which readily conducts the field of the preferably glued permanent magnet segments MS on the adhesive side. Alternatively, the magnetic segment support may be formed of a non-magnetic material such as aluminum, plastic, etc. However, when using a non-magnetic material, the efficiency of the corresponding actor of the adjustment device decreases, since the magnetic field of the permanent magnet segment or permanent magnet segments are not guided, as a result of which negatively influencing stray fields form.
[0156] In the embodiments described above, it may in particular be provided that the coil axis AS runs along the flexure hinge rotation axis D1. As an alternative to this, it can be provided that the relative movement direction of the relative movement between the coil 70 and at least one permanent magnet segment of a drive device C runs transversely to a plane which is spanned by the flexure hinge rotation axis of the adjustment body and of the adjustment body connection device on which the respective actuator is coupled. In this case, it can also be provided that the coil axis runs transversely to the flexure hinge rotation axis D1.
[0157] The mode of operation of the adjustment device 1 according to the invention with the actor 60 is as follows:
[0158] The actor 60 is actuated by electrically controlling the coil 71 so that this current flows. As a result, the coil 71 generates in its interior a magnetic field whose magnetic field lines in the interior of the coil 71 or of the coil housing 72 extend in or along the coil axis AS. This coil magnetic field produces in cooperation or in interaction with the magnetic field generated by a permanent magnet segment MS, a force between the one permanent magnet segment MS and the coil 71, which provides a deflection force for the desired adjustment movement or tilting of the adjustment body, results in an attractive force between the one permanent magnet segment MS and the compensation component 80 due to the corresponding displacement between the permanent magnet segment MS and the coil 71. The actuating movement can cause the permanent magnet segment MS and the coil 71 to move relative to one another in a direction in which, as seen in the coil axis AS, the relevant permanent magnet segment MS comes to the height or into the region of the compensation component 80.
[0159] This comprises the effect that the resulting attractive force counteracts a return movement inclination of the adjustment body, caused by the deflected or elastically deformed flexure hinges.
[0160] The force (attractive force) produced during current flow in the coil between the compensation component 80 and the permanent magnet segment MS acts in a direction which is opposite to the direction of the movement of the permanent magnet segment MS generated on the basis of the deflection force relative to the coil 71. In this way, this attractive force counteracts the restoring force which the at least one flexure hinge exerts on the adjustment body 10 with the occurrence of the actuating movement of the same. In this case, the adjustment device 1 is designed in such a way that the drive device or its components, the compensation component and the permanent magnet segment MS at least partially, i.e., partially or completely, compensates the restoring force which the at least one flexure hinge exerts on the adjustment body 10.
[0161] In this context, the said two positions of the compensation component relative to the permanent magnet segment are defined in particular by: a first relative position, which is an initial relative position, which is realized in particular in the case of the reference state of the actor 60, and in which no or only very small or only very small or negligible attraction forces exist between the compensation component and the permanent magnet segment, and a second relative position, which is an adjustment relative position, in which the compensation component 80 is situated in a region in which a greater interaction between the compensation component and the permanent magnet segment exists so that there is a stronger attractive force between the permanent magnet segment and the compensation component than in the first relative position.
[0162] The reference state of the actor 60 or of the adjustment device 1 is understood here in particular to mean the state which the actor 60 assumes when the coil 71 is not electrically actuated and from which the permanent magnet segment MS and the coil 71 move relative to one another when the coil 71 is electrically activated or activated.
[0163] In each of the embodiments of the adjustment device 1 according to the invention, the at least one drive device C can each comprise at least one permanent magnet segment MS and in particular one or two or four permanent magnet segments MS, but also a different number of permanent magnet segments MS. For example, a drive device C of the adjustment device 1 according to the invention can comprise two permanent magnet segments MS, which, for example, are fastened on a magnetic segment support 53, wherein the permanent magnet segments MS are situated on the same side of the actuator 60 as seen from the center Z or the coil axis AS. The magnet segment carrier 53 can be plate-shaped. The size of the magnetic segment support 53 is preferably provided in such a way that the two permanent magnet segments MS are completely situated on an outer surface of the magnetic segment support 53. In this case, the two permanent magnet segments MS can be situated on that outer surface of the magnetic segment support 53 which is situated facing the coil 71. Thus, the two permanent magnet segments MS fastened to the magnet segment carrier 53, when viewed in a viewing direction which runs along the direction of the distance between the adjustment body rotation axis D1 and the coil axis AS, are arranged on one side of the coil 71 or of the coil housing 72. Such a configuration of the actuator 60 is illustrated in
[0164] The reference signs MS11, MS12 are assigned to the two permanent magnet segments arranged on the magnetic segment support 53. The permanent magnet segments MS11, MS12 arranged on a magnetic segment support 53 are arranged beside one another as viewed from the center Z or the coil axis AS and as seen in the direction of the coil axis AS and are arranged one behind the other in the directions of the relative movements between the coil 71 and the at least one permanent magnet segment MS. Also, the individual permanent magnet segments MS11, MS12 are arranged one behind the other in the direction of the relative movement between the coil 71 or permanent magnet segments MS11, MS12. Preferably, the two permanent magnet segments MS11, MS12 arranged on a magnetic segment support 53 are separated by a continuous gap 55, which extends in each case along the direction of the distance between the adjustment body rotation axis D1 and the coil axis AS, when this distance passes through the center Z.
[0165] In this embodiment, the permanent magnet segments MS11, MS12 are polarized from the adjustment body rotation axis D1 in different directions directed in or along the coil axis AS. This is illustrated by way of example in
[0166] The compensation component 80 may be formed or made of a soft magnetic material. Alternatively, the compensation component 80 can be formed from a hard magnetic material and comprise two polarization regions 81, 82. In this case, in the case of a reference state or the zero position of the drive device, the center line of the compensation component 80, which runs along the direction of the distance between the adjustment body rotation axis D1 and the coil axis AS, is situated between the first permanent magnet segment MS11 and the second permanent magnet segment MS12. In embodiments in which the permanent magnet segments MS11, MS12 are separated by a continuous gap 55, in the reference state or in the zero position, this center line is situated at the height of the gap 55 in the directions of the relative movements between the coil 71 and the permanent magnet segments MS11, MS12. In this zero position, a first polarization region 81 is polarized in such a way that its magnetic field line direction R81 runs along the magnetic field line direction RMS11 of the first permanent magnet segment MS11 and that its magnetic field line direction R82 runs along the magnetic field line direction RMS12 of the second permanent magnet segment MS12.
[0167] In particular in the embodiments of the adjustment device 1 with a drive device C, in which permanent magnet segments MS11, MS12, as seen from the adjustment body rotation axis D1, are located on only one side of the coil 71, the shaping of the compensation component 80 can be provided according to the compensation component shown in
[0168] In these embodiments, the side surface 111, which faces the arrangement of the permanent magnet segments MS11, MS12, can comprise two, in particular straight-surfaced or spherical partial surface portions 113, 114, the orientations of which extend at an angle between 10 degrees and 40 degrees with respect to the coil axis AS, wherein the angles in the zero position or in the reference state, viewed from the center Z, open in one direction in which the respectively closer permanent magnet segment MS11, MS12 of the arrangement of permanent magnet segments is situated.

[0187] The compensation elements 380, 390 may each be formed or made of a soft magnetic material or a hard magnetic material. In
[0188] In variants of this embodiment of the actor 60, it can be realized in such a way that. the same comprises only one of the two compensation elements 380, 390, that is to say either the compensation element 380 which is located on the first coil section 75 or the compensation element 390 which is located on the first coil section 76. This is in particular the case when the actuator 60 is realized in such a way that only one permanent magnet segment MS is arranged on one side or on both sides of the coil 71. In these variants, the respective compensation element 380, 390 is situated on that coil section 75, 76, which at least partially overlaps or covers the respective coil section 75, 76 when seen in the coil axis AS, at least in the reference state.

[0189] The embodiment of the drive device C shown in
[0190] The deflection or movement of the actor 60 in an adjustment state, caused by the energization of the coil 71 in cooperation with the permanent magnet segments, leads to magnetic field line distributions which can likewise be taken from
[0191] The force acting between the compensation component 80 and the corresponding permanent magnet segments MS11, MS12, MS21, MS22 is dependent on the deflection of the adjustment body 10 and is greater than the absolute value=0 as soon as the actor 60 is deflected out of the reference state. The deflection of the adjustment body 10 is determined by the current flowing through the coil 71: The current-dependent actor force arises from the interaction between the magnetic field of the permanent magnet segments and the current density within the coil 71 (Lorentz force). The attractive force which is produced between the compensation component 80 and the permanent magnet segments is largely independent of the electric current conducted through the coil. The force effect between the compensation component 80 and the permanent magnet segments results from the tendency of the energy minimization between the outer magnetic field, which is caused by the permanent magnet segments, and optionally the own magnetic field of the compensation component 80 or its magnetic permeability, depending on the embodiment of the actor 60.
[0192] If, on the other hand, for example, the coil 71 is electrically energized in such a way that current flows in the first coil section 75 in a direction which is directed away from the adjustment body rotation axis D1 and current in the second coil section 76 flows in a direction which is directed towards the adjustment body rotation axis D1, this together with the magnetic field line directions RMS11, RMS12, RMS21 and RMS22 causes a deflection of the actor 60 in a direction opposite to the deflection according to
