Definitions
- the invention relates to a small electrical device with a drive device for generating an oscillating movement.
- the small device can in particular be an electric razor or an electric toothbrush.
- an oscillating armature drive for dry shaving devices with a reciprocating working movement of a shear knife is known.
- the known rocker arm drive has an electromagnet which is fixedly connected to the housing of the shaving device and is U-shaped.
- an oscillating compensating anchor In the vicinity of the poles of the fixed electromagnet there is a working anchor and on both sides of the working anchor there is an oscillating compensating anchor each symmetrically.
- the working anchor which drives the shear knife, swings parallel to the pole faces of the electromagnet, the compensating anchors executing an oscillation movement in phase opposition to prevent transmission of the vibrations of the working anchor to the housing of the shaving device as far as possible.
- DE 196 80 506 T1 discloses an electric shaver with an oscillating linear motor which has a stationary electromagnet and a plurality of movable components which are set into oscillatory movements in phase opposition to one another with the aid of the electromagnet. In order to maintain the phase relationship of the movable components to one another even under load, these are connected to one another by means of a link mechanism which transmits the oscillatory movement from one to the other movable component while reversing the direction.
- an electric razor with a linear drive which has a hollow cylindrical stator with an electromagnetic coil.
- Two movable elements are arranged in the stator, which are driven in phase opposition to one another and one of which drives a shear knife and the other can have a counterweight to suppress unwanted vibrations.
- the invention has for its object to generate an oscillating movement in a small electrical device in the best possible way.
- the invention is characterized in that the first drive component for executing a movement oscillating in phase opposition to the second drive component is arranged to be movable in the small electrical device and that the center of gravity of the first drive component and the second drive component including components moving with the first drive component or the second drive component move on a common straight line.
- the two drive components oscillate in phase opposition to one another, a significantly higher relative speed is achieved between the drive components than in a conventional drive in which only one drive component moves and the other drive component is at rest. Since the efficiency in such drives increases with the relative speed of the drive components to one another, the small device according to the invention achieves a higher efficiency than comparable known small devices. Furthermore, the movement of the focal points on a common straight line prevents an angular momentum from being generated by the drive and, as a result, undesirable vibrations being transmitted, for example, to the housing of the small device.
- the small device can be designed according to the invention in such a way that the pulses of the first drive component and the second drive component including components moving with the first drive component or the second drive component are opposite in the same way.
- This has the advantage that a further source for the generation of undesired vibrations, namely a resulting linear pulse, can be switched off.
- the first drive component and the second drive component mesh with one another.
- At least one of the two drive components can have one or more permanent magnets.
- at least one of the two drive components can have a winding core on which the coil is arranged. This allows a powerful drive to be implemented with relatively small dimensions, the current consumption of which is sufficiently low to allow, for example, battery operation of the small device according to the invention.
- At least one elastic element for generating restoring forces can be provided in the drive device of the small device according to the invention.
- an oscillatory system is formed, which is preferably operated under resonance conditions.
- the elastic element is designed in particular as a leaf spring which is fastened to the first drive component and to the second drive component. The leaf spring thus counteracts a deflection of the two drive components relative to each other and has the advantage that it takes up very little space.
- the first drive component and the second drive component are mechanically coupled to one another by at least one coupling element.
- the coupling element is rotatably articulated to the first drive component and to the second drive component.
- the two drive components also perform a transverse movement, ie they move slightly transversely to the direction of vibration described. It is therefore advantageous if the coupling element is articulated to at least one of the drive components with play transverse to the direction of movement of the drive components.
- the coupling element can be used to produce an antiphase between the two drive components in that the coupling element is rotatably mounted.
- the coupling element is rotatably mounted on a fastening axis for fastening the drive device to the small device according to the invention.
- the fastening axis can be arranged off-center between the articulation of the coupling element on the first drive component and on the second drive component. This has the advantage that different vibration amplitudes can be generated in a very simple manner and without an additional gear, the relationship of which to one another does not change even when the drive components are loaded.

- Fig. 6 shows the two engine components of Fig. 5 in the assembled state in a perspective view.
- FIGS. 1 and 2 are used first.
- the embodiment of an electric razor with an oscillating linear motor shown in FIGS. 3 to 6 is then discussed in more detail, with both the figurative representation and the associated description being restricted to the drive system of the razor.
- the other design of the razor can be done in the usual way and is not specifically described.
- Fig. 1 shows a schematic diagram of an embodiment for an oscillating linear motor of the small device according to the invention.
- the linear motor has two movable motor components 1 and 2, which are arranged at a short distance from one another.
- the first motor component 1 consists of a rod-shaped iron core 3 and an ner wound from wire coil 4.
- the second motor component 2 has two pairs of permanent magnets 5.
- the permanent magnets 5 of each pair are arranged next to one another on a common carrier plate 6 with polarity oriented in anti-parallel.
- the carrier plate 6, like the iron core 3, is made of an iron material and is U-shaped. As indicated in FIG. 1, the carrier plate 6 can optionally be designed as a closed, rectangular frame in order to reduce magnetic stray fields.
- the following description relates in each case to a U-shaped design of the carrier plate 6, but can be applied analogously to a design as a frame.
- the permanent magnets 5 are each attached to the inside of the two legs of the U-shaped support plate 6.
- the iron core 3 is arranged between the opposing pairs of permanent magnets 5 such that an air gap 7 exists between the two end faces of the iron core 3 and the respectively adjacent pair of permanent magnets 5.
- two springs 8 are fastened to the side of the iron core 3 and extend parallel to the legs of the carrier plate 6 to the bottom thereof and are also fastened there.
- the first motor component 1 and the second motor component 2 are movably suspended so that they can execute a movement parallel to the legs of the carrier plate 6, ie a movement in the horizontal direction in the illustration of FIG. 1. Taking the springs 8 into account, this results in an oscillatory system in which the first motor component 1 and the second motor component 2 each perform a linear oscillatory movement.
- the directions of movement of the two motor components 1 and 2 are each opposite to each other, that is. the vibrations are in phase opposition to each other.
- An essential aspect of the invention is that the center of mass of the first motor component 1 and the second motor component 2 move on a common straight line. This means that no angular momentum results from the movement of the two motor components 1 and 2.
- the two motor components 1 and 2 in the embodiment shown in FIG. 1 are each formed symmetrically and also arranged symmetrically to one another.
- the physical symmetry in the design or arrangement of the engine components 1 and 2 is, however, not absolutely necessary. If, in addition, the linear pulses of motor components 1 and 2 occurring during the movement of the two motor components 1 and 2 are opposite at all times, the linear motor generates no vibrations in a suspension that supports it, for example the housing of an electric razor.
- the linear motor is in its equilibrium position, ie the springs 8 are neither stretched nor compressed. Without the action of external forces, motor components 1 and 2 remain in this position, since restoring forces generated by springs 8 have to be overcome for a deflection in the horizontal direction. If the two motor components 1 and 2 are deflected relative to one another by the action of a force, the return forces generated by the springs 8 drive a return to the equilibrium position. In order to generate the force required for a deflection, a current flow through the coil 4 is established.
- the coil 4 acts as an electromagnet and, supported by the iron core 3, generates a magnetic field which acts on the permanent magnets 5 and results in a relative movement between the coil 4 and the permanent magnets 5. 1, the relative movement runs in the horizontal direction.
- the magnetic field generated by the coil 4 can be reversed by appropriate control, so that the first and the second motor components 1 and 2 are set in oscillations in opposite phase to one another.
- An essential aspect of the invention is that both the first motor component 1 and the second motor component 2 move, that is to say that the linear motor does not have a stator, with the aid of which a rotor is driven, but two motor components 1 and 2 which vibrate against one another, that drive each other.
- One of these motor components 1 or 2 corresponds to the rotor of a conventional linear motor.
- the other takes over the functions of the stator of a conventional linear motor, but in contrast to this is not static, but also moves.
- this also leads to the fact that, under otherwise identical conditions, the first and second motor components 1 and 2 of the linear motor according to the invention move relative to one another at a relative speed which is twice as high as the relative speed between a stator and a rotor of a conventional linear motor. As a result, a relatively high degree of efficiency can be achieved in the linear motor according to the invention.
- the frequency of the oscillatory movement of the two motor components 1 and 2 is predetermined via the control of the coil 4 and, in particular, is set so that it corresponds to the resonance frequency of the oscillation system which is formed by the two motor components 1 and 2 and the springs 8. Under resonance conditions, the vibration behavior is very robust and only a comparatively small amount of energy is required.
- Fig. 2 shows a schematic diagram of a further embodiment for an oscillating linear motor of the small device according to the invention.
- the Eisenkem 3 formed as a rectangular frame, in which one side has an opening 9. The three remaining sides of the frame are continuous and each carry a coil 4, so that a total of three coils 4 are present.
- Arranged in the opening 9 is a pair of antiparallel oriented permanent magnets 5 which are rod-shaped overall, the permanent magnets 5 in turn being separated from the iron core 3 by air gaps 7.
- the spring 8 is clamped between the side of the iron core 3 opposite the opening 9 and the permanent magnet 5.
- the permanent magnets 5 are mechanically coupled to the iron core 3 via two struts 10, each of which overcomes one of the air gaps 7.
- each strut 10 has a first bore 11 and a second bore 12 for pivotable articulation on the iron core 3 and the permanent magnet 5. Furthermore, each strut 10 in the area between the first bore 11 and the second bore 12 has a third bore 13 for fastening the linear motor, for example to a housing, not shown in the figure.
- the struts 10 serve to couple the two motor components 1 and 2 in terms of movement. This coupling causes the two motor components 1 and 2 to move exactly in phase opposition to one another at any time, since the motor fastening takes place spatially between the articulation on the first motor component 1 and the articulation on the second motor component 2. In other words, if the first motor component 1 moves to the left in the illustration in FIG.
- the second motor component 2 simultaneously moves to the right and vice versa. Since the distance between the points of the articulation on the two motor components 1 and 2 varies slightly during this movement, the bores 11 and 12 are designed as elongated holes, so that the articulation takes place with a certain amount of play.
- a special feature of the exemplary embodiment shown is that the third bore 13 is not arranged centrally between the bores 11 and 12, but closer to the first bore 11 for articulation on the iron core 3 of the first motor component 1.
- the two engine components 1 and 2 vibrate with different vibration amplitudes.
- the speeds at which the two motor components 1 and 2 move are correspondingly the opposite of one another. So that the linear impulses of the two motor components 1 and 2 can also have opposite values in this exemplary embodiment, the first motor component 1 is designed so that it has a greater mass than the second motor component 2.
- This geometry can be used, for example, in an electric razor where one or more shear knife should perform rapid oscillation movements with a large amplitude and a shaving head should oscillate in opposite phase with a small amplitude.
- the shaving knife or the shaving knives are driven by the second motor component 2 and the shaving head by the first motor component 1.
- Fig. 3 shows an embodiment of an oscillating linear motor of an electric shaver in a perspective view.
- An associated exploded view is shown in Fig. 5.
- the razor shows only a few components that are directly connected to the linear motor. For the sake of clarity, the shaving head was not shown.
- the other design of the razor can be done in a conventional manner.
- the designations according to FIG. 2 are used for corresponding components, the specific design of the components and also of the entire linear motor partly deviating considerably from FIG. 2.
- the linear motor is mounted on a base plate 14 which is firmly connected to a housing of the razor, not shown in the figure.
- Two stepped bolts 15 are let into the base plate 14 and are guided through the third bores 13 of the struts 10.
- the two motor components 1 and 2 are rotatably articulated to the struts 10 via four perforated bearing blocks 16.
- two pins 17 are provided on each strut 10, onto which the bearing blocks 16 are attached, there being a certain amount of play between the pins 17 and the bores 11 or 12 of the bearing blocks 16.
- the two bearing blocks 16 each of which is attached to a strut 10, one is fastened to the first motor component 1 and the other to the second motor component 2.
- the two motor components 1 and 2 are suspended in such a way that they can move parallel to the longitudinal side of the base plate 14 within certain limits.
- the two motor components 1 and 2 are connected to one another by a total of four springs 8 designed as leaf springs, by means of which restoring forces are generated when deflected from the equilibrium position shown.
- a shear knife 18 With the first motor component 1 and the second motor component 2, a shear knife 18 is firmly connected, so that the two shear knives 18 are driven in phase opposition to one another.
- the illustrated embodiment of the linear motor has the iron core 3 with the coil 4 and the permanent magnets 5, as well as a number of other components which are not of particular interest in the context of the invention and which are therefore not dealt with in more detail.
- FIG. 5 shows the two motor components 1 and 2 of the linear motor from FIG. 3 as separate units in a perspective view.
- Fig. 6 the two engine components 1 and 2 are shown assembled.
- FIGS. 5 and 6 it should be noted that to illustrate further details in FIGS. 5 and 6 a rear view is shown, ie the object shown is rotated by 180 ° about a vertical axis.
- the two engine components 1 and 2 are constructed in such a way that they engage in a comb-like manner.
- This makes it possible to make the linear motor very compact and still achieve the angular momentum compensation already mentioned, i. H. to design the mass distributions of the two engine components 1 and 2 in such a way that their centers of mass move on a common straight line.
- the engine is suspended on the bolts 15 in the middle between the linkage to the first engine component 1 and to the second engine component 2.
- the two engine components 1 and 2 move with the same amplitude and the same amount of speed.
