[0058] Fig.12 Shown with Fig.11An example similar to the example shown in . DETAILED DESCRIPTION

[0059] The figures relate to exemplary embodiments and are shown schematically.

[0060] The exemplary actuator has a mainly symmetrical structure of pole plates 5 and magnets 6, which comprises a double gap with two substantially oppositely oriented magnetic fields. For example, to achieve this, the two magnets are arranged oppositely with respect to each other in their magnetization directions. At least one substantially rectangular coil is arranged in the gap, so that the outgoing winding and the return winding of the coil interact with the positively oriented magnetic field or the negatively oriented magnetic field, thereby generating a force excitation by means of the Lorentz force in the case of a current-carrying coil.

[0061] The exemplary design of the arrangement allows adhesive-free assembly. On the one hand, the frame 1 allows adhesive-free mounting of the pole plates 5 and magnets 6 by guiding them during assembly and positioning them after assembly. On the other hand, engaging the upper housing or half-shell 22 with the lower housing 23 under preload allows force-locking engagement with the spring element 18 and the coil assembly 14 including the coil carrier and the coil.

[0062] For example, the frame 1 provides the possibility of guiding the pole plates 5 and the magnets 6 on the side walls and the upper and lower defining parts of the frame during assembly. The pole plates 5 and the magnets 6 are inserted, for example, to a geometric stop, which is implemented as a spacer bar 4. In the exemplary embodiment in which the corresponding magnets 6 and two pole plates 5 (referred to as assembly A 9 or magnet pole plate group) are inserted into both sides of the frame 1 and the magnets 6 are reversed in polarization direction (the frame 1, magnets 6 and pole plates 5 after assembly are referred to as assembly B10), the magnetic force 12 acts between the opposite pole plates of the two assemblies A 9 or magnet pole plate groups. In addition, the magnetic force 11 also acts between the magnets 6 and the pole plates 5 of the corresponding assembly A 9. This causes all the pole plates 5 and magnets 6 to attract each other, so that they are fixed in this arrangement in a manner positioned by the frame 1. In the preferred case of producing frame 1 by means of plastic injection molding, the demoulding bevel of the injection molding tool has a positive effect on the fixation of pole plates 5 and magnets 6, because the insertion area into frame 1 thus narrows with increasing insertion length and additionally mechanically clamps pole plates 6 and magnets 5.

[0063] For example, the recess 3 in the frame 1 allows the insertion of a respective assembly A 9 consisting of a pole plate 5 and a magnet 6 by means of an assembly tool 13. An optional mounting chamfer 27 on the frame 1 may facilitate the insertion of the respective assembly A 9 in the assembly step A7.

[0064] By way of example, the frame 1, for example with the pole plates 5 and the magnets 6 inserted therein, is connected to the upper housing 22 and the lower housing 23 via spring elements 18. At least one stop buffer 28 is respectively fitted to the surface of the frame 1 facing the spring elements 18, which stop buffer mitigates mechanical shocks in the event of a sharp deflection of the frame 1 relative to the housings 22, 23. In this case, the stop buffer 28 can be completely integrated into the frame 1 and made of the same material, but can also be an additional component, which is connected to the frame 1, for example, by an adhesive connection.

[0065] In an exemplary assembly step C15 , the coil assembly 14 consisting of at least one coil 16 and at least one coil carrier 17 is inserted into the frame 1 through the slot 2 .

[0066] The spring element 18 is assembled to the coil assembly 14, for example in an assembly step D 21. The spring element 18 is placed on the end face of the coil assembly 14. In this case, the spring element 18 has recesses at those locations where the coil assembly 14 has mounting lugs 19, thereby allowing positioning. The spring element 18 is connected to the pole plate 5 via a connection point 20. The spring element 18 is preferably welded to the pole plate 5. As a preferred alternative, the spring element 18 is not connected to the pole plate 6 but directly to the frame 1, for example by means of heat caulking of the plastic of the frame 1.

[0067] The frame 1 with the pole plate 5 and the magnet 6 inserted is connected to the coil assembly 14, for example, via the spring element 18. The upper housing 22 and the lower housing 23 are connected in the separation plane 26. The upper housing 22 and the lower housing are joined under preload so that a static pressure 25 is generated. The static pressure 25 acts between the upper housing 22 and the lower housing 23, whereby the coil assembly 14 is clamped in the housing together with the spring element 18. This results in a force-locking connection. The mounting lug 19 of the coil assembly 14 can optionally be additionally embedded in the housing groove 24 in the upper housing 22 and the lower housing 23 to establish an additional form-locking connection. Preferably, the joining of the two housings 22, 23 for generating the static pressure 25 is performed by a friction welding process or a laser welding process, which is particularly preferably performed using a force-displacement controlled machine.

[0068] The exemplary engagement of the upper housing 22 and the lower housing 23 in the separation plane 26 generates a static pressure 25, which connects the spring element 18 and the coil assembly 14 in a force-locking manner. A compensation layer 29 containing an elastic material is preferably inserted between the spring element 18 and one of the housings 22, 23 and / or between the spring element 18 and the coil assembly 14, thereby introducing the static pressure 25 in a more evenly distributed manner over the force transmission surface. The compensation layer can contain plastic, elastomer, silicone or rubber, for example. Perforated and / or bent metal (e.g. leaf spring, disc spring) is also possible.

[0069] Figure 1 An exemplary embodiment of a frame 1 is shown, which has slots 2 for passing coils and / or coil carriers, recesses 3 for making room for assembly tools, and spacing bars 4 for positioning or orienting magnets and pole plates. The frame 1 can optionally have mounting chamfers 27 as an assembly aid, which can be formed on some or all insertion edges.

[0070] Figure 2 An exemplary embodiment of a frame 1 is shown, which surrounds pole plates 5 and magnets 6. At least one pole plate 5 is in contact with at least one magnet 6 on at least one side thereof, optionally for example via a thin intermediate layer, such as an adhesive layer. The frame 1 is realized such that it can accommodate at least one component comprising at least one pole plate 5 and at least one magnet, and completely or partially surrounds the frame on at least three sides.

[0071] Figure 3 An exemplary embodiment of mounting pole plates 5 and magnets 6 in a frame 1 is shown. In assembly step A 7, at least one pole plate 5 is connected to at least one magnet 6, thereby producing assembly A 9. The connection in assembly step A 7 can be established, for example, by means of an adhesive connection, or in an adhesive-free manner by the magnetic attraction between the pole plate 5 and the magnet 6. At the time of assembly step A7, the magnet can optionally be pre-magnetized or in an unmagnetized state. In assembly step B 8, the joined assembly A 9 is inserted into the frame 1, thereby producing assembly B10. The connection in assembly step B 8 can be established, for example, by means of an adhesive connection, or in an adhesive-free manner by the magnetic attraction between the pole plate 5 and the magnet 6.

[0072] Figure 4A cross-sectional view through a frame 1 and an exemplary embodiment of pole plates 5 and magnets 6 is shown. Magnetic forces 11 in component A hold at least one pole plate 5 and at least one magnet 6 together. Magnetic forces 12 in component B ensure that the pole plates and magnets of the respective components A attract each other. In this case, the frame 1 positions and orients the pole plates 5 and magnets 6 relative to each other. Adjacent components A are spaced apart in the frame 1 by at least one spacing bar 4. The entire component B is joined and held by the combination of the magnetic attraction forces 11, 12 and the frame 1.

[0073] Figure 5 An exemplary embodiment of the process of installing pole plates 5 and magnets 6 into a frame 1 is shown. Here, the assembly tool 13 grabs a stack (assembly A 9) comprising at least one magnet 6 and at least one pole plate 5. On the basis of assembly step B 8, at least one magnet 6 and at least one pole plate 5 are inserted into the frame 1. The recess 3 in the frame 1 allows the engagement of the assembly tool 13.

[0074] Figure 6 A cross-sectional view through the frame 1 and an exemplary embodiment of a pole plate 5 and a magnet 6 is shown. In an assembly step C15 , a coil assembly 14 consisting of at least one coil 16 and at least one coil carrier 17 is inserted into the frame 1 through the slot 2 .

[0075] Figure 7 An exemplary embodiment of an actuator with a spring element 18 is shown. In an assembly step D 21, the spring element 18 is assembled to the coil assembly 14. The spring element 18 is placed on the end face of the coil assembly 14. In this case, the spring element 18 has recesses at those locations where the coil assembly 14 has mounting lugs 19, thereby allowing positioning. The spring element 18 is connected to the pole plate 5 via a connection point 20.

[0076] Figure 8 A cross-sectional view through an exemplary embodiment of an actuator is shown. The frame 1 with the pole plate 5 and the magnet 6 inserted is connected to the coil assembly 14 via the spring element 18. The upper housing 22 and the lower housing 23 are connected in a separation plane 26. The upper housing 22 and the lower housing are joined under preload so that a static pressure 25 is generated. The static pressure 25 acts between the upper housing 22 and the lower housing 23, whereby the coil assembly 14 is clamped in the housing together with the spring element 18. This results in a force-locking connection. The mounting lugs 19 of the coil assembly 14 can optionally be additionally embedded in the housing grooves 24 in the upper housing 22 and the lower housing 23 to establish an additional form-locking connection.

[0077] Fig. 9A cross-sectional view through an exemplary embodiment of an actuator is shown. The frame 1 with the pole plates 5 and magnets 6 inserted is connected to the upper housing 22 and the lower housing 23 via spring elements 18. At least one stop buffer 28 is respectively mounted on the surface of the frame 1 facing the spring elements 18, which stop buffer reduces mechanical shocks in the event of a sharp deflection of the frame 1 relative to the housings 22, 23.

[0078] Fig.10 A cross-sectional view through an exemplary embodiment of an actuator is shown. The joining of the upper housing 22 and the lower housing 23 in the separation plane 26 generates a static pressure 25 which connects the spring element 18 and the coil assembly 14 in a force-locking manner. A compensation layer 29 containing an elastic material is preferably inserted between the spring element 18 and one of the upper housings 22, thereby introducing the static pressure 25 in a more evenly distributed manner over the force transmission surface.

[0079] Fig.11 An exemplary embodiment of a frame 1 is shown in which the recess has a chamfer, which is produced, for example, by the injection molding process and is shown here in a more pronounced manner for the sake of clarity. In addition to the form-fitting connection, the chamfer also allows the magnet pole plate sets 6, 5 to be mounted in a force-fitting manner.
