Description

device for adjusting the angle of rotation

technical field

The invention relates to a device for adjusting the rotation angle.

Background technique

Such a device for adjusting the angle of rotation can be used as an angle of rotation encoder, wherein an electrical signal is generated which is associated with the corresponding adjustment of the angle of rotation. A rotary angle encoder, such as this one with a handle for manual adjustment of the rotary angle, can also be used in a suitable manner as an electric rotary switch.

A device in the form of an electric rotary switch for adjusting the angle of rotation can be known from US-A-4054860. This device has a stator and a rotor mounted on the stator so that it can turn. The magnets are located on the rotor and are precision permanent magnets, which means that the magnets move with the rotor. The magnetic field sensors face the magnet, they are precision Hall sensors arranged in a mount on the unit. The rotor can be moved between two or more rotational angular positions, so that the magnetic field sensor generates a signal from the magnetic field induced by the magnet, which is associated with the corresponding rotational angular position.

In an exemplary embodiment of US-A-4 054 860, the stator has a socket which is open on one side and is generally pot-shaped. The socket serves as an axis of rotation for the rotor. The magnetic field sensor is positioned on a printed circuit board, which in turn is mounted in the socket. The stator thus serves as a mount for the magnetic field sensor.

A comparable keyed switch as a starter lock for a construction machine is disclosed in WO 00/58986A. A magnetic field sensor, which operates according to Hall's principle and is produced on a chip using a complementary metal-oxide-semiconductor integrated circuit (CMOS) process, is described in: by Steiner, R. et al, "In-Plane Sensitive Vertical Trench -Hall Device," ELECTRON DEVICES MEETING, 1998, IEDM'98 TECHNICAL DIGEST., INTERNATIONAL SANFRANCISCO, CA, USA, 6-9DEC 1998, PISCATAWAY; NJ, USA, IEEE, US, December 6, 1998, pages 479 to 482. This magnetic field sensor senses parallel to its two-dimensional chip surface. However, the scientific publication does not disclose any details about the arrangement of the magnetic field sensor within such a rotary switch.

A disadvantage of these known devices has been found to be its complexity, which makes the rotary switch expensive and easily damaged. Such a device therefore requires two or more magnets and two or more magnetic field sensors. A supplementary mount is required to line up the magnetic field sensors. On the whole, it is therefore also a rotary switch with large dimensions, which cannot be used in compact electrical equipment, especially such a rotary switch is not suitable for arrangement on a printed circuit board, which holds the electronic device for evaluation in the A signal from a magnetic field sensor in the control panel of an electrical appliance, such as a washing machine or dishwasher. Furthermore, the documents dealing with these rotary switches do not contain information on tolerance problems in assembly or similar processes, which can lead to falsification of the signal generated by the magnetic field sensor when the rotor is in the starting position. Furthermore, the manufacturing process also means that the magnetic field sensor (which is an integrated semiconductor circuit) is also subject to tolerances in the generated signal. This known rotary switch is therefore not suitable for automated mass production.

US 5 644 225 discloses the calibration of a device for measuring the angle of rotation, which has a permanent magnet and a magnetic sensor, wherein the calibration process is carried out in a complicated manner by applying a relevant supplementary magnetic field to the permanent magnet, magnetizing it . This correction does not seem to be suitable for the smaller size of the rotary switch.

Contents of the invention

The object underlying the invention is to provide a device for adjusting the angle of rotation, which is suitable for being arranged in a simple manner on a printed circuit board, for example on a control panel or the like, and which is especially dimensionally very small. Furthermore, the device can be designed to allow compensation of tolerances after assembly, especially in a simple manner.

For this general-purpose device for adjusting the rotation angle, the above-mentioned purpose can be achieved by means of the following technical solutions.

In the case of the device according to the invention, in particular in the form of an electric rotary switch, the stator has a socket, open on one side and pot-shaped, and also has a the rotor, so that the rotor can rotate in the socket as a rotating bearing, so that the rotor can be moved between at least two angular positions, and has a magnet, which can be moved by means of the rotor, and has a magnetic field sensor, which is connected to the magnet Cooperating to produce a signal corresponding to the angular position, the magnetic field sensor is arranged in a socket on the stator and/or on a part mounted in the stator, so that the stator functions as a mount for the magnetic field sensor, which It is characterized in that the magnets are arranged on the rotation axis of the rotor, and that the magnetic field sensor is in the form of a Hall sensor, which two-dimensionally senses the magnetic field parallel to its chip surface, and that the magnetic field sensor is mounted on the underside of the stator The lower side is on the side remote from the open side of the receptacle.

In the case of the device according to the invention, the magnet can be similarly arranged so that it can be moved so as to adjust its position relative to the rotor, thus allowing the adjustment of the magnet relative to the signal generated by the magnetic field sensor within one rotational angular position of the rotor. Location. The mechanical zero point defined by the rotor can thus be connected to the electrical zero point defined by the magnetic field sensor during this adjustment process.

Other improvements of the present invention are preferred technical solutions.

The stator and/or the rotor can be made of plastic, in particular thermoplastics such as polyamide can be chosen for this purpose. The stator or rotor can then conveniently be produced as an injection-molded part, so that these elements can be produced in a simple and inexpensive manner.

The device for adjusting the angle of rotation can be designed to be particularly compact by virtue of its substantially complete positioning in the socket. In this modification, a surface of the socket, which is located inside the stator, acts in a direct manner as a rotational bearing.

In order to secure the rotor in the socket so that it cannot come out, cooperating locking elements can be arranged in the socket between the stator and the rotor. The magnetic field sensor can be mounted on the side of the socket away from the open side, that is to say on the lower surface of the stator.

The conductor tracks for the electrical connection of the magnetic field sensor can be arranged in a space-saving manner in the stator and the conductor tracks extend suitably into the socket. The magnetic field sensors can then be soldered, welded, bonded with conductive adhesive or the like directly to the conductor track, so that the conductor track simultaneously becomes part mounted on the stator for the alignment of the magnetic field sensor. If the magnetic field sensor is a sealed chip with connecting wires, the connecting wires can then be soldered in this case to the conductor tracks in order to establish electrical contact. To simplify the process of inclusion, the chip may use components in the form of surface mount devices (SMD). If the magnetic field sensor is a non-encapsulated chip, subsequently bonded wires, which are soldered specifically to the chip, can be used to establish electrical contact of the conductor tracks.

An inexpensive method of producing conductor tracks is to form them in the shape of a metal stamped grid. The stamped grid is then injected directly into the plastic as an injection molded part in one process of stator production. Alternatively, the conductor track can also be incorporated into the stator in the form of a molded interconnect device (MID) element. This is achieved, for example, by using metallized plastic as conductor tracks.

In order to save a separate housing, the outside of the stator can be made in the shape of a housing. The installation of the means for adjusting the angle of rotation can be simplified by means of alignment locks and/or snap-action snap rings on the housing for mounting the stator to the abutment. The open side of the receptacle in the stator suitably faces the support so that the support covers the opening of the stator and at the same time forms a housing cover. The use of a printed circuit board for the carrier is particularly advantageous with regard to price and compactness. The conductor tracks in the stator can then be made compact and the associated conductor tracks on the printed circuit board, that is to say the electrical connection for the rotary switch is established via the printed circuit board. It is also possible to arrange an electronic device on the printed circuit board in order to evaluate the signal generated by the magnetic field sensor. If desired, the printed circuit board can also be equipped with a panel for an electrical device or the like, so that the rotary switch according to the invention is suitable for being arranged directly in a simple manner on a plate of an electrical device.

For ergonomic operation of the rotary switch, the rotor can have a recess into which a handle can be inserted in the open side of the socket. For example, it may be possible to turn the handle manually by means of an axis. If the handle is located on a side of the support which is remote from the housing, then an opening, which corresponds to the open side of the receptacle in the stator, can be located in the support through which the shaft advances for insertion into the groove.

Especially when the device is used as an electric rotary switch, the rotational angular position of the rotor is preferably in the form of a locking position, thus making it possible to achieve a defined switching position in an ergonomically controlled manner. The rotary switch in particular emits a signal voltage. It is therefore advantageous to additionally position an electrical switch with a conventional electromechanical contact system in the housing of the rotary switch as a main switch, so that the rotary switch can also switch the mains voltage at the same time. Rotary switches of this type can be commonly used on electrical equipment.

As mentioned above, adjustments can be provided to compensate for possible tolerances in the production of the device for adjusting the angle of rotation according to the invention. The adjustment process can be carried out in a particularly simple manner in order to subsequently adjust the magnet to the starting position, if the magnet is installed in the rotor, so that it can rotate. A socket is suitably arranged for this purpose inside the rotor, facing the magnetic field sensor. Furthermore, an adjustment device for adjusting the position of the magnet can be arranged between the magnet and the rotor, in order in this way to ensure the possibility of proper adjustment using simple means. It is possible that the adjusting means take the form of an intermediate piece which is mounted in the socket of the rotor so that it can turn, and the magnet itself is mounted on the intermediate piece.

Despite its adjustment possibilities, the device for adjusting the angle of rotation can be designed to be particularly compact by making the magnets accessible from the outside of the stator. Access is provided through a socket in the stator, which is open on one side and serves as a rotational bearing for the rotor. A hole is then suitably positioned in the rotor extending from the surface of the rotor facing the open side of the socket to the magnet and/or to the intermediate plate. For fine adjustment, a Torx-type, cross-shaped slot or similar socket can be positioned within the magnet and/or within the middle piece, facing the hole. This allows adjustment through the bore, in this case by means of a tool which can be inserted into the socket, for example by means of a threaded taper.

In order to fix the adjusted position of the magnet, it can be attached to the rotor so that it does not rotate. This can be accomplished by adhesive bonding, welding, casting the magnets and/or intermediate pieces to the rotor, or otherwise securing after adjustment.

Magnets are manufactured from a material that has magnetic particles and plastic reinforcement, it is compact and cheap because it saves components. This material is moulded, precision formed by means of injection molding into a single piece, so that this single piece represents both the middle piece and the magnet.

The advantages obtained by the invention are, inter alia, that the stator is in the shape of a single element carrying two or more functions at the same time. Furthermore, there is no need for any separate element for supporting the sensor, for example a commonly used printed circuit board. It leads to assembly advantages and in particular allows the device to be manufactured in an automated manner. Furthermore, the device is very small in size, thus allowing it to be used even in confined spaces. Finally, the price of the device is also lower than ordinary devices.

Furthermore, placing the magnetic field sensor directly on the stator leads to a reduction of the tolerance chain. All mechanical tolerances created between the magnetic field sensor and the magnet are eliminated. If desired, the magnets can be adjusted for this purpose, during which the mechanical zero point of the device is connected with the electrical zero point. This results in a defined starting state, which makes it possible to reliably distinguish between a large number of rotational angle positions or switching positions. Thus, despite being compact in size, the device has more angular positions of rotation than conventional devices and can therefore meet more stringent requirements.

Exemplary embodiments of the present invention and various developments and improvements will be described in more detail below with reference to the accompanying drawings, wherein:

FIG. 1 shows a perspective view and a partial sectional view of a device in the form of a rotary switch for adjusting the angle of rotation.

FIG. 2 shows a perspective view of the stator of FIG. 1 as a separate component.

FIG. 3 is a cross-sectional view taken along line 3-3 of FIG. 2 . as well as

Figure 4 is a sectional view similar to Figure 3, corresponding to a different modification.

Detailed ways

FIG. 1 shows a device for adjusting the angle of rotation and its use primarily as an electric rotary switch 1 . Such a rotary switch 1 can be arranged, for example, as a program selector switch on the panel of a household electrical appliance, such as a washing machine, dishwasher or the like.

A rotary switch 1 has a stator 2 and a rotor 3, and it is mounted on the stator 2 so that it can rotate. A magnet 4 can be moved by means of the rotor 3 . The magnet 4 has an associated magnetic field sensor 5 . In particular, the magnet 4 is a cylindrical permanent magnet, which is preferably diametrically magnetized two-dimensionally, that is to say that one half of the cylinder with a semicircular cross-section represents the magnet north pole and the other half the cylinder represents the magnet south pole. Magnetic field sensors, especially Hall sensors, preferably sense two-dimensionally a magnetic field parallel to the surface of the Hall sensor chip. The rotor 3 can be moved between at least two rotational angles, thereby changing the magnetic field, which is generated by the magnet 4 in the region of the magnetic field sensor 5, so that the magnetic field sensor generates a signal corresponding to the corresponding rotational angle position.

According to the invention, the stator 2 has a socket 8 which is open on one side 6 and has approximately the shape of a pot, as can be seen from FIG. 2 or 3 . The socket 8 forms a rotational bearing for the rotor 3 . The magnetic field sensor 5 is arranged in the socket 8 directly on the stator 2 and/or mounted on a part of the stator 2 . Since the magnetic field sensor 5 is mounted on the stator, the stator 2 also serves as a mount for the magnetic field sensor 5, thereby avoiding the mounting plate that would otherwise normally be used for the magnetic field sensor in the switch. Furthermore, the stator 2 also assumes the function of a rotational bearing for the rotor 3 and, if required, the function of a housing.

Various developments and other improvements of the rotary switch 1 will be explained in more detail below.

The magnetic field sensor 5 is mounted on a side 7 of the socket 8 which is remote from the open side 6 of the rotor 3 . The rotor 3 is positioned substantially within the socket 8, as can be seen from FIG. 1 . For reasons of compactness, the rotor 3 can be positioned completely within the socket 8 . A surface 25 of the socket 8, which is positioned inside the stator 2, then functions as a rotational bearing. In order to secure the rotor 3 so that it cannot come out of the socket 8 , cooperating locking elements 26 , as shown in FIG. 3 , can be arranged between the stator 2 and the rotor 3 . Furthermore, an integrated conductor track 9 can also be positioned inside the stator 2 in order to electrically connect the magnetic field sensor 5 to the external connection 10 on the rotary switch 1 . The conductor track 9 extends into the socket 9 . The stator 2 thus advantageously becomes a multifunctional part which not only simultaneously holds the rotor 3 and the magnetic field sensor 5 but also provides the electrical connections for the magnetic field sensor 5 .

The stator 2 and/or the rotor 3 can be produced from plastic, specifically a thermoplastic, for example it can be polyamide. The stator 2 and/or the rotor 3 may suitably be produced as injection molded parts. In a refinement, the conductor track 9 is made in the form of a metal stamped grid. The stamped grid is subsequently sprayed with plastic as an injection molded part in the stator 2 production process. In this case, the magnetic field sensors 5 can also be supported by a solid stamped grid, so that the conductor tracks 9 then form part of the installation in the stator 2 in order to line the magnetic field sensors 5 . In another refinement, the conductor tracks 9 are incorporated into the stator 2 in the form of a molded interconnect device (MID). For example, the conductor track can in this case be produced from metallized plastic, which can also be injected during the production of the injection-molded part of the stator 2, and/or which can then be electrochemically treated with metal.

It can be seen from FIG. 4 that the magnetic field sensor 5 is in the form of a sealed chip, specifically in the form of a surface mount device (SMD). The chip has connecting wires 11 which are then soldered to conductor tracks 9 in order to establish electrical contact. The magnetic field sensor 5 can also be in the form of an unsealed chip, as shown in FIG. 3 . In this case, connecting wires 24 are used to establish electrical contact with the conductor track 9 and are soldered at one end to the chip and at the other end to the conductor track 9 . The situation described above in particular offers the advantage of saving space over a sealed chip, so that the rotary switch 1 can be designed more compactly.

The outside of the stator 2 can be designed in the form of a casing 12, the details of which can be seen from FIG. 2 . Locking and/or snap action clasps 13 can be used to mount the stator 2 to a standoff 14 , shown in FIG. 1 , provided on the housing 12 . The open side 6 of the receptacle 8 in the stator 2 may suitably face the seat 14 . The support 14 is a printed circuit board and brings the conductor tracks 9 in the stator 2 into contact via electrical connections 10 with the associated conductor tracks on the printed circuit board. An electronic unit 15 , which is only indicated schematically in FIG. 1 , can be positioned on the printed circuit board for evaluating the signal generated by the magnetic field sensor 5 . The printed circuit board, which is in the form of a support 14, can also be provided with a panel for an electrical device or the like. The stand 14 itself can also serve as a flat plate for the device if desired.

It can be seen from FIG. 1 that the rotary switch 1 is equipped with a handle 16 as an operating device. The handle 16 allows the rotor 3 to be turned manually. The handle 16 has a shaft 17 for insertion of the handle 16 into a recess 18 , which can be seen in FIG. 2 , and the open side 6 of the socket 8 positioned in the rotor 3 . The handle 16 is preferably positioned on that side of the support 14 facing away from the housing 12 . An opening 19 , which corresponds to the open side 6 of the socket 8 in the stator 2 , is located in the seat 14 . The shaft 17 is advanced through the opening 19 for insertion into the groove 18 .

A locking system, which is not shown in any detail, can be arranged on a plate of the electric device for changing the position of the rotary switch 1 on which the handle 16 is arranged. However, the position switching of the rotary switch 1 is preferably provided by the rotational angular position of the rotor 3 in the form of a locked position, although this too is not shown in any detail in the figures. Furthermore, a common electrical switch, not shown in any detail, can also be accommodated in the housing 12 of the rotary switch 1 and be used as the main switch of the electrical device. This main switch can likewise be conveniently switched by means of the handle 16 . Such a rotary switch 1 can then be used not only to switch the mains voltage, but also to generate a signal voltage which corresponds to the switched position of the handle 16 and which is used to initiate specific functions of the electrical device.

When the rotary switch 1 is assembled, the position of the magnet 4 is fixed relative to the magnetic field sensor 5 . The signal emitted by the magnetic field sensor 5 at the rotational angular position of the rotor 3 depends on this position. After mounting the magnetic field sensor 5 it is often possible to digitally adjust the zero position of the magnetic field sensor 5 using an appropriate signal for zero positioning. However, it will then be able to reliably reproduce only a small number of switching positions due to the tolerances of the magnetic field sensor 5 in combination with the mechanical locking of the handle 16 of the shaft 17 of the rotor 3 . According to the invention, the magnet 4 is now arranged in such a way that it can be moved relative to the rotor 3 to adjust its position in order to compensate for tolerances during assembly. This allows the position of the magnet 4 to be adjusted at one rotational angular position of the rotor 3 so that the magnetic field sensor 5 emits a signal corresponding to the zero position.

As can be seen from Figure 3, the magnet 4 is preferably mounted on the rotor 3 so that it can be rotated to adjust its position. For this purpose, a socket 20 is positioned inside the rotor 3 facing the magnetic field sensor 5 . It is then possible to arrange an adjustment device between the magnet 4 and the rotor 3 in order to adjust the position of the magnet 4 . The adjustment means take the form of an intermediate piece 21 mounted on the rotor 3 so that it can turn in the socket 20 . The magnet 4 is mounted on the intermediate piece 21 again.

The magnet 4 is now accessible from the outside of the stator 2 and thus also from the outside of the housing 12 for adjustment. The socket 8 , which is open on one side 6 , is used for this purpose and at the same time acts as a rotational bearing for the rotor 3 in the stator 2 . Furthermore, there is a bore 22 in the rotor 3 . The hole 22 extends from a surface facing the open side 6 of the socket 8 to the magnet 4 and/or the intermediate piece 21 . A Torx-type, cross-shaped slot or similar socket 23 is positioned inside the magnet 4 and/or intermediate piece 21 facing the hole 22 . This allows adjustment through the hole 22 by means of a tool which can be inserted into the socket 23, for example by means of a threaded taper.

After assembly, the rotor 3 is moved to the zero position. This tool is then used to turn the magnet 4 and the rotor 3 fixed in the zero position, for example by means of a locking system, until the magnetic field sensor 5 emits a signal corresponding to the zero position. The adjusted position of the magnet 4 is then connected to the rotor 3 such that it cannot rotate. For this purpose, the magnets 4 and/or the intermediate pieces 21 can be joined to the rotor 3 after adjustment by adhesive bonding, welding, casting or the like. After doing so, the handle 16 can then be inserted into the groove 18 . After this the hole 22 is closed.

In another refinement, although no details are shown in the figures, the magnets 4 are not arranged on the intermediate piece 21 . In this case, the magnet is manufactured from a material with magnetic particles and plastic. This material is molded as a single piece, which simultaneously assumes the corresponding functions of the magnet 4 and the intermediate piece 21 . Such a single piece represents both the intermediate piece 21 and the magnet 4 , thus saving a part of the production of the rotary switch 1 . Such a monolithic piece can be produced, for example, by injection molding of this material.

The invention should not be restricted to the described and illustrated exemplary embodiments, but rather it also includes all specific developments within the scope of the inventive concept. The invention can thus be used not only for electric rotary switches, but also for angular and/or rotary encoders, for example in machine tools, automobiles or similar vehicles.
