- FIGS. 1-3 A first exemplary embodiment of the invention is explained in FIGS. 1-3.
- 1 shows a plan view of the entire rotation rate sensor
- FIG. 2 shows a detailed view of part of the rotation rate sensor
- FIG. 3 shows a side view of a cross section through FIG. 2.
- FIG. 1 shows a plan view of a substrate 1, not shown in FIG. 1, in which a first Coriolis element 100 and a second Coriolis element 200 are arranged.
- the first and the second Coriolis element 100, 200 are designed as rectangular, frame-shaped structures.
- the frame-shaped Coriolis elements 100 and 200 surround detection means 101, 201, which are shown in simplified form in FIG. 1 as grid lines. The detection means are shown in the detailed view in FIG. 2 and explained in more detail below.
- the frame-shaped Coriolis elements 100, 200 are surrounded by largely rectangular, frame-shaped drive elements 102, 202, each of which is perforated on the sides facing one another. Through these openings, the Coriolis elements 100, 200 are connected to one another by means of a coupling spring 52.
- the coupling spring is designed so that it is designed to be soft both in the X direction and in the Y direction.
- the connection between the drive elements 102, 202 and the Coriolis elements is made by spiral springs 103, 203.
- the spiral springs are designed so that they are soft in the X direction and are rigid in the Y direction.
- Movable electrodes 104, 204 are fastened to the drive elements 102, 202 and engage comb-like in fixed electrodes 105, 205.
- the fixed electrodes 105, 205 are firmly connected to the substrate 1 by means of bearing blocks 106, 206.
- the drive elements te 102, 202 connected by means of springs 107, 207 to further bearing blocks 106, 206, which are also firmly connected to the substrate 1.
- the rotation rate sensor is thus only connected to the substrate 1 via the bearing blocks 106, 206. Both the Coriolis elements 100, 200 and the drive elements 102, 202 can thus be moved as desired relative to the substrate 1. The movement of these elements is only determined by the spring elements 103, 203 and 107, 207.
- the springs 107, 207 are designed so that they are soft in the Y direction and stiff in the X direction.
- the drive elements 102, 202 can thus essentially only move along paths that are parallel to the Y direction.
- the Coriolis elements 100, 200 are connected to the drive elements 102, 202 via the springs 103, 203.
- the Coriolis elements 100, 200 can thus move relative to the drive elements 102, 202 essentially only in the X direction.
- the drive elements 102, 202 move in a direction that is parallel to the Y direction, the Coriolis elements 100, 200 are of course also moved in these directions. Relative to the substrate 1, the Coriolis elements 100, 200 are thus movable both in a direction parallel to the Y direction and in the X direction.
- a center of gravity 110, 210 is also specified for each of the Coriolis elements 100, 200.
- the focal points are in the center of the frame-shaped Coriolis elements 100, 200.
- the drive elements 102, 202 are excited to vibrate. Accordingly, the Coriolis Elements 100, 200 excited to vibrate.
- the center of gravity 110, 210 of the Coriolis elements 100, 200 then moves in each case on an axis that is parallel to the Y axis.
- the movements of the two Coriolis elements 100, 200 thus take place in axes which are formed parallel to one another.
- the focal points move without the action of a Coriolis force (ie without a rotational movement of the substrate about an axis that is perpendicular to the substrate 1) on straight lines that are parallel to one another.
- Coriolis elements 100, 200 act on Coriolis forces which are perpendicular to the axis of rotation and are perpendicular to the axis of movement. These forces then act in the X direction.
- the movable electrodes 104, 204, together with the fixed electrodes 105, 205 and the drive elements 102, 202 thus form excitation means by which the Coriolis elements 100, 200 are excited to vibrate, in which the axes of vibration of the centers of gravity 110, 210 are parallel to one another are aligned. These axes are arranged at a certain distance from one another, which is at least the lateral extent of one of the Coriolis elements 100, 200 in the X direction.
- the two Coriolis elements 100, 200 are connected by means of a coupling spring 52, which is designed to be soft both in the X direction and in the Y direction.
- This coupling spring achieves a frequency separation of the vibration modes of the Coriolis elements 100, 200 in the X and Y directions.
- the spring stiffness of the springs 107, 207 must be taken into account.
- the spring stiffness of the springs 107, 207 and the spring stiffness of the coupling spring 52 in the Y direction must also be taken into account. term.
- the spring stiffness of the springs 103, 203 must be taken into account.
- the spring stiffness of the coupling spring 52 in the X direction must also be taken into account.
- the natural frequencies of the in-phase vibrations in the X and Y directions thus differ from the frequency of the antiphase vibrations, which is a targeted excitation of the different vibrations
- the coupling spring 52 is designed here as a simple clover leaf spring. But this is only one possibility. In general: 5 all elements are suitable which are soft in both the x-direction and the y-direction.
- “soft” is understood to mean a spring stiffness which allows the Coriolis elements to be deflected relative to the substrate under the forces that usually occur. What is soft
- the coupling spring is to be designed in such a way that a sufficiently strong frequency separation of the parallel and antiparallel vibration modes both in the X direction and in
- the coupling spring is to be designed in such a way that mechanical non-linearities are minimized and a stress-decoupled connection between the Coriolis elements is created.
- the movement in the X direction takes place on a common axis.
- the advantage of this principle is that a rotational acceleration around the Z axis cannot exert a direct influence on the movement of the Coriolis elements 100, 200, since these are not deflected by a rotational acceleration around the Z axis.
- the rotation rate sensor is therefore particularly insensitive to rotational accelerations around the Z axis.
- FIG. 2 shows an enlarged detailed view of the evaluation means 101 of the Coriolis element 100 from FIG. 1.
- the frame-shaped Coriolis element 100 surrounds the evaluation means 101. These are designed as grid-shaped electrodes 121, a plurality of grid-shaped electrodes 121 being provided within the frame-shaped structure of the Coriolis element 100. For stabilization, these grid-shaped electrodes 121 are also connected to one another by a central bar 130. Each of the electrodes 121 moves together with the Coriolis element 100.
- the electrodes 121 are arranged between fixed electrodes 122, 123, which are fastened on the substrate 1 by bearings 106.
- the electrodes 112, 123 are thus designed as fixed electrodes that do not move relative to the substrate.
- FIG. 3 shows a cross section along the line III-III of FIG. 2.
- FIG. 3 shows in cross section the substrate 1 and an interconnect 130 arranged on the surface of the substrate Anchors 106 attached and thus firmly connected to the substrate ' 1.
- the bearings 106 and also the electrodes attached to them are electrically conductive and are connected in parallel by the conductor 130.
- Each of the movable electrodes 121 is arranged between a fixed electrode 122 and a fixed electrode 123. In this way, two capacitors are formed, on the one hand between the movable electrode 121 and the electrodes 122 and on the other hand between the movable electrode 121 and the fixed electrodes 123.
- FIG. 3 shows in cross section very clearly that the Coriolis element 100 is arranged above the substrate 1 and that the electrodes 121 connected to the Coriolis element 100 are also arranged above the substrate 1.
- the cross section through the bearing blocks 106 of the electrodes 122 is shown, which are arranged on the conductor track 130 through the bearing blocks 106 and are thus firmly connected to the substrate 1.
- the electrodes 123 are also shown in the cross section of FIG. 3 above the substrate. However, at another point they are firmly connected to the substrate 1 via a corresponding conductor 130 for these electrodes.
- silicon is preferably used as the material, which is made conductive by appropriate doping.
- the substrate can pass through insulating layers where it is necessary to be electrically isolated.
- other materials such as ceramics, glass or metals can also be used for the senors.
- the desired antiphase vibrations can thus be generated by targeted feeding in of appropriate frequencies.
- FIG. 4 shows the supervision of a further embodiment.
- FIG. 4 shows a plan view of a substrate 1, on which, as in FIG. 1, Coriolis elements 100, 200 are arranged, which are surrounded by drive elements 102, 202, which are passed through on the respective facing sides.
- Coriolis elements 100, 200 and drive elements 102, 202 are again connected with springs 103, 203.
- the drive elements 102, 202 are connected to bearing blocks 106, 206 by means of springs 107, 207.
- a frame-shaped detection element 140, 240 is provided inside the frame-shaped Coriolis elements 100, 200 for the detection of the deflection of the Coriolis elements 100, 200.
- 15 elements 140, 240 are also rectangular frame Structures that are connected to the substrate 1 by means of spring elements 141, 241 with bearing blocks 106, 206.
- the spring elements 141, 241 are soft in the X direction and stiff in the Y direction and thus essentially only allow the detection frames 140, 240 to be deflected in the X direction.
- the detection frames 140, 240 are connected to the corresponding Coriolis elements 100, 200 by spring elements 142, 242.
- the spring elements 142, 242 are designed to be soft in the Y direction and stiff in the X direction and thus transmit the Coriolis forces particularly well in the X direction.
- Grid-shaped detection electrodes 143, 243 are again arranged in the interior of the detection frames 140, 240, which are only indicated in FIG. 4. A detailed view of these elements corresponds again to FIGS. 2 and 3.
- the advantage of this arrangement can be seen in the fact that the grid-shaped electrodes 143, 243 can essentially only be moved in the X direction and thus there is no transverse movement relative to the fixed electrodes.
- the movable electrodes 121 are connected directly to the Coriolis element 100, so that these movable electrodes carry out a movement both in the X direction and in the Y direction.
- the movement in the X direction is necessary for measuring the deflection of the Coriolis element 100 in the X direction.
- movement in the Y direction is not desirable for the measurement and can be a possible source of errors.
