A shortcoming that has been found that these known devices is its complexity, and it causes costing an arm and a leg of rotating switch and be easy to damaging.So the two or more magnet of this matching requirements and two or more magnetic field sensor.An additional mount pad requires to be used to arrange magnetic field sensor.Generally speaking, therefore it also be the big rotating switch of size, it can not use in the electric equipment of compactness, especially like this a kind of rotating switch is not suitable for being arranged on the printed circuit board (PCB), its keeps electronic installation to be used to estimate in the control panel of electric equipment from the signal of magnetic field sensor, and these electric equipment are such as being washing machine or dishwasher.In addition, the file that relates to these rotating switches does not comprise the information of the tolerance issues in relevant assembling or the similar operation, and it can cause when rotor is in the starting position mixing by the signal of magnetic field sensor generation.In addition, manufacture process means that also magnetic field sensor (it is an integrated semiconductor circuit) also stands the tolerance of the signal that produces.Therefore this known rotating switch is not suitable for a large amount of productions of automation.
US 5 644 225 openly measures the correction of a kind of device that rotational angle uses, and it has a permanent magnet and a magnetometric sensor, and wherein trimming process is carried out with a kind of mode of complexity, by applying relevant additional magnetic field to permanent magnet, makes its magnetization.As if this correction be not suitable for the less rotating switch of size.
Summary of the invention
The present invention according to purpose provide a kind of device that rotational angle is used of regulating, it is suitable for being arranged in a simple manner on the printed circuit board (PCB), for example on a control panel or similarity piece, and it is very little especially dimensionally.In addition, device can be designed to allow after assembling tolerance compensating is especially used a kind of simple mode.
For regulating this universal device that rotational angle is used, above-mentioned purpose can reach by following technical scheme.
Under situation according to device of the present invention, especially it is the form with a kind of electric rotating switch, this stator has a socket, this socket, open and be a jar shape side, and also has a rotor that is installed on the stator, make rotor in socket, to rotate as a rotating support, thereby rotor can be moved between at least two angle positions, also has a magnet, it can move by rotor, and has a magnetic field sensor, it matches with magnet, so that produce a signal, this signal is corresponding to angle position, magnetic field sensor is arranged in the socket on the stator and/or on the part in being installed in stator, thereby stator is worked as a mount pad of magnetic field sensor, it is characterized in that, magnet array is on the rotation axis of rotor, and magnetic field sensor is the form of a Hall transducer, and described transducer is to the magnetic field of the chip surface that is parallel to it sensing two-dimensionally, and, magnetic field sensor is installed on the downside of stator, and this downside is positioned at that side away from the open side of socket.

Other improvement of the present invention is an optimized technical scheme.
Stator and/or rotor can be used the plastics manufacturing, thermoplastics especially, and for example polyamide can select to be used for this purpose.Stator or rotor can be subsequently aptly as injecting molded part productions, thereby these elements can be produced in a kind of mode of simple and inexpensive.
The device that the adjusting rotational angle is used can be designed to compact especially, and it is by especially intactly being positioned in the socket in fact.In this kind improvement, a surface of socket, it is positioned at the inside of stator, plays the effect of a rotating support in a kind of direct mode.
For fixed rotor in socket, it can not be deviate from, interactional latch member can be arranged in the socket between stator and the rotor.Magnetic field sensor can be installed on the side of socket, and it is away from open side, in other words, and on the lower surface of stator.
The conductor rail of the electrical connection usefulness of magnetic field sensor can be arranged in the stator with a kind of mode of saving the space, and makes conductor rail suitably extend into socket.Magnetic field sensor is soldering subsequently, and welding directly is engaged to conductor rail with electrically conducting adhesive connection or similar method, makes conductor rail meanwhile become a part that is installed on the stator like this, so that arrange magnetic field sensor.If magnetic field sensor is a chip that has the sealing of connecting line, connecting line can be brazed to conductor rail in the case subsequently, electrically contacts so that set up.In order to simplify the process that comprises, chip can use the element of surface-mount devices (SMD) form.If magnetic field sensor is a unsealed chip, the lead of Jie Heing subsequently, it is specifically to be soldered to chip, can be used to set up electrically contacting of conductor rail.
A kind of inexpensive conductor rail production method is the shape that is made into the metal stamping grid.The grid of punching press is directly injected subsequently and is entered plastics, as the injecting molded part in the process of stator production.The scheme that replaces is that conductor rail also can merge in the stator with the form of a molding interconnect device (MID) element.The mode that realizes this point is, for example, by the plastics that use the spray metal as conductor rail.

As mentioned above, can provide adjusting with compensation issuable tolerance when producing the device of using according to adjusting rotational angle of the present invention.Adjustment process can be carried out with simple especially mode, so that regulating magnet is to the starting position subsequently, if magnet is mounted in the rotor, it can rotate like this.A socket suitably is arranged in the rotor for this purpose, in the face of magnetic field sensor.In addition, the adjusting device that the regulating magnet position is used can be arranged between magnet and the rotor, so that guarantee to use the possibility of the suitable adjusting of simple device by this way.Possible adjusting device adopts the form of an intermediate, and it is installed in the socket of rotor, it can be rotated, and magnet self is mounted on the intermediate.
Although it has the possibility of adjusting, the device that the adjusting rotational angle is used can design compactly especially, and it is by making magnet enter adjusting by the stator outside.Entering is that a socket by in the stator provides, and it is open and use as a rotating support of rotor a side.A hole suitably is positioned in the rotor subsequently, and it extends to magnet by the surface of the rotor of faces socket open side and/or to intermediate.For meticulous adjusting, a Torx type, cross slits or similar socket can be positioned in the magnet and/or in intermediate, faces aperture.Allow like this to regulate, at this moment by an instrument that can insert socket, for example by a screw thread screw driver by the hole.
For the adjusting position of fixed magnet, can be connected to rotor it is not rotated.Realize that this point can engage by bonding agent, welding, casting magnet and/or intermediate are perhaps fixed with other method after adjusting to rotor.
Magnet is by a kind of made, and it has magnetic-particle and plastics reinforcing agent, and it is compact, also is cheap, because it has saved element.This material is a molding, by as a whole of injection-molded precision form, makes this single piece represent intermediate and magnet simultaneously.
The advantage that the present invention obtains especially, stator is the shape of an individual component, has two or more functions simultaneously.In addition, be used for supporting sensor without any need for independent element here, for example, the printed circuit board (PCB) of common use.It causes the advantage of fit on, especially allows device to make in a kind of mode of automation.Moreover, install very for a short time dimensionally, therefore allow it even in affined space, use.At last, also the device than common is low for the price of device.
Moreover, directly place magnetic field sensor causes tolerance chain on stator reduction.The whole mechanical tolerances that produce between magnetic field sensor and magnet are eliminated.If desired, magnet can be regulated for this purpose, and in this process, the mechanics of device is connected with electric zero point zero point.The initial state that causes a qualification like this, it makes might difference reliably between the rotational angle position of larger amt or the position of the switch.Therefore, although compact dimensionally, device has than the more rotational angle of common device position, and therefore can satisfy stricter requirement.

Embodiment
Fig. 1 illustrates one and regulates the device that rotational angle is used, and it uses mainly as an electric rotating switch 1.This rotating switch 1 for example can be used as a sequence selector switch and is arranged on the panel of a household electric appliances, such as washing machine, and dishwasher or similar machine.
Rotating switch 1 has a stator 2 and a rotor 3, and it is installed on the stator 2, so it can rotate.A magnet 4 can move by rotor 3.Magnet 4 has a subsidiary magnetic field sensor 5.Special is, magnet 4 is cylindrical permanent magnets, and it preferably presses the diameter magnetization two-dimensionally, and in other words, on behalf of the magnet arctic and second half cylinder, the semicolumn with semi-circular cross-section represent the magnet South Pole.Magnetic field sensor is the Hall transducer particularly, and it is preferably to the magnetic field that is parallel to Hall sensor chip surface sensing two-dimensionally.Rotor 3 can move between two rotational angles at least, thereby changes magnetic field, and it is to be produced in the zone of magnetic field sensor 5 by magnet 4, makes magnetic field sensor produce a signal that cooperates with corresponding rotational angle position like this.
According to the present invention, stator 2 has a socket 8, and it is 6 open and be roughly a jar shape a side, as by Fig. 2 or 3 findings.Socket 8 forms a rotating support of rotor 3 usefulness.Magnetic field sensor 5 is arranged in the socket 8, directly on the stator 2 and/or be installed on the part of stator 2.Because magnetic field sensor 5 is mounted on the stator, stator 2 is simultaneously also as a mount pad of magnetic field sensor 5 usefulness, thereby avoided mounting panel, otherwise it will normally be used in magnetic field sensor in switch.In addition, stator 2 is also born the function of the rotating support of rotor 3 usefulness, and if desired, also bears the function of housing.
The various development of rotating switch 1 and other improve and will explain in more detail hereinafter.
Stator 2 and/or rotor 3 can be used the plastics manufacturing, and clear and definite is a kind of thermoplastics, and for example it can be a polyamide.Stator 2 and/or rotor 3 can be aptly as injecting molded part productions.In an improvement, conductor rail 9 is forms of making a kind of metal stamping grid.The grid of punching press sprays plastics subsequently, as the injecting molded part in stator 2 production processes.In such cases, magnetic field sensor 5 also can be by firm punching press grid supporting, thereby conductor rail 9 is formed subsequently be installed in the part in the stator 2, so that arrangement magnetic field sensor 5.In another improved, conductor rail 9 was that the form with a molding interconnect device (MID) merges in the stator 2.For example, conductor rail can made by the plastics of spray metal in such cases, and it also can be injected in the production of the injecting molded part of stator 2, and/or it carries out electrochemical treatments with metal subsequently.
As seen from Figure 4, magnetic field sensor 5 is forms of the chip of a sealing, and clear and definite is the form of a surface-mount devices (SMD).Chip has connecting line 11, and it is brazed to conductor rail 9 subsequently, electrically contacts so that set up.Magnetic field sensor 5 also can be the form of a unsealed chip, as shown in Figure 3.In such cases, connect lead 24 and be used to set up and the electrically contacting of conductor rail 9, and at one end be soldered to chip and at the other end to conductor rail 9.Above-described situation provides the space-saving advantage of the chip that surpasses sealing especially, thereby makes rotating switch 1 design compactlyer.
The outside of stator 2 can be designed as the form of a housing 12, as seen from Figure 2 its details.Locking and/or quick acting clasp 13 can be used to install 2 to bearings 14 of stator, and it is shown in Fig. 1, is arranged on the housing 12.The open side 6 of stator 2 interpolation blocks 8 is faces seat 14 aptly.Bearing 14 is printed circuit board (PCB)s, and make in the stator 2 conductor rails 9 by be electrically connected 10 with printed circuit board (PCB) on relevant conductor rail foundation contact.An electronic installation 15, it only points out schematically that in Fig. 1 it can be positioned on the printed circuit board (PCB), is used to estimate the signal that is produced by magnetic field sensor 5.Printed circuit board (PCB), it also can be equipped with a panel as the form of bearing 14, is used for electric equipment or similar device.If desired, the flat board that also can be used as of bearing 14 itself is used for equipment.
As seen from Figure 1, rotating switch 1 is equipped with a handle 16, as an operating means.Handle 16 allows rotor 3 manually to be rotated.Handle 16 has an axle 17, and it is used to insert 16 to grooves 18 of handle, and it can be seen in Fig. 2, and the open side 6 that is positioned at the socket 8 in the rotor 3.Handle 16 preferably is positioned on that side away from housing 12 of bearing 14.An opening 19, it is positioned in the bearing 14 corresponding to the open side 6 of the socket 8 in the stator 2.Axle 17 advances by opening 19, so that be inserted into groove 18.
A locking system, it does not illustrate any details, and it can be arranged on the position that is used to change rotating switch 1 on the flat board of electric equipment, arranges handle 16 on this flat board.Yet, the position conversion of rotating switch 1, preferably the rotational angle position by rotor 3 provides, and it is the form that is in locked position, though this point does not illustrate any details in the drawings too.In addition, common electric switch that any details is not shown also can be contained in the housing 12 of rotating switch 1 and use as the main switch of electric equipment.This main switch can be changed equally aptly by handle 16.This rotating switch 1 can be used in subsequently not only changes principal voltage, also can produce signal voltage, and it is corresponding to the dislocation of handle 16, and it is used in the specific function of the electric equipment of beginning.
When assembling rotating switch 1, the position of magnet 4 is fixing with respect to magnetic field sensor 5.The signal of being launched by magnetic field sensor 5 in the rotational angle position of rotor 3 depends on this position.After magnetic field sensor 5 is installed, allows and often might use an appropriate signals digitlization ground to regulate the dead-center position of magnetic field sensor 5 so that zero location.Yet it will only can reproduce a spot of dislocation subsequently reliably, and this is the tolerance of the generation because magnetic field sensor 5 combines with the mechanics locking of the handle 16 of the axle 17 of rotor 3.According to the present invention, magnet 4 is arranged now like this, and it can be moved to regulate its position, so that compensate the tolerance when assembling with respect to rotor 3.Allow the position of magnet 4 to be conditioned like this in a rotational angle position of rotor 3, thus the signal that magnetic field sensor 5 emissions are matched with dead-center position.
As seen from Figure 3, magnet 4 preferably is installed on the rotor 3, and it can rotate so that regulate its position like this.For this purpose, a socket 20, it is positioned in the rotor 3 in the face of magnetic field sensor 5.An adjusting device might be arranged between magnet 4 and the rotor 3 subsequently, so that the position of regulating magnet 4.Adjusting device is used the form of an intermediate 21, and it is installed on the rotor 3, and it can rotate in socket 20 like this.Magnet 4 is installed on the intermediate 21 once more.
Magnet 4 can be arrived by the outside of stator 2 now, therefore also can be arrived by the outside of housing 12 so that regulate.Socket 8, it is 6 openings a side, are used in this purpose, and meanwhile a rotating support of the rotor 3 of conduct in stator 2 works.In addition, in rotor 3, also has a hole 22.Hole 22 extends to magnet 4 and/or intermediate 21 by a surface of the open side 6 of faces socket 8.A Torx type, cross slits or similar socket 23 are positioned at faces aperture 22 in magnet 4 and/or the intermediate 21.Allow like this to regulate, at this moment by an instrument that can insert socket 23, for example by a screw thread screw driver by hole 22.
After the assembling, rotor 3 moves to dead-center position.The rotor 3 that this instrument is used in rotor magnet 4 subsequently and is fixed on dead-center position, for example signal that matches with dead-center position up to magnetic field sensor 5 emissions by locking system.The adjusting position of magnet 4 is connected to rotor 3 subsequently, and it can not be rotated.For this purpose, magnet 4 and/or intermediate 21 can engage with bonding agent after regulating, welding, and casting or similar approach are engaged to rotor 3.After doing like this, handle 16 can insert groove 18 subsequently.Hole 22 sealings after this.
In another improved, though any details is not shown among the figure, magnet 4 was not arranged on the intermediate 21.In such cases, magnet is by the made with magnetic-particle and plastics.This material is molded as a whole, and it bears the function corresponding of magnet 4 and intermediate 21 simultaneously.Such single piece is represented intermediate 21 and magnet 4 simultaneously, has therefore saved the part that rotating switch 1 is produced.Such single piece for example can be with the injection-molded manufacturing of this material.
The present invention should not be limited to one exemplary embodiment described and explanation, and on the contrary, it also is included in the whole special development in the concept and range of the present invention.Therefore the present invention not only can be used in electric rotating switch, but also can be used in angle and/or rotary encoder, for example, is used in machine tools, automobile or similar vehicles.
