In this magnetic system, multiple sensors (such as 5 sensors) be will be necessary to sense or detect rotation The rotation of button, multiple sensor can be such as Hall sensor or Hall element.Due to multiple or a large amount of sensings Device, magnetic system can be complicated and expensive.
The object of the present invention is to provide the magnetic systems of a kind of reduction of complexity and cost reduction.
Summary of the invention
The embodiment of the present invention is related to a kind of magnetic knob system.Magnetic knob system includes: plate, has positioning magnet;And Knob has complementary positioning magnet.Complementation positioning magnet has complementary poles relative to the magnetic pole of positioning magnet.Magnetic knob system Knob can also onboard rotate, wherein knob is separable with plate.Knob includes vertically moving element, and magnetic rotation The magnetic sensor circuit of button system is configured as detecting the change for vertically moving caused magnetic field by vertically moving element.
Therefore, magnetic knob system mainly includes two parts or element: plate and knob.In the first mode of operation, it revolves Button can be attached to plate, and in the second mode of operation, and knob can be separated from plate.Herein, advantage may is that knob It can be removed from plate, such as in the case where not needing knob.For example, if the equipment with magnetic knob system is closed, It does not need then to adjust the equipment, so that knob can be removed and, for example, be stored.The advantage of second operator scheme may is that Even if plate is also possible to plane when knob is separated.Therefore, another advantage of second operator scheme, which may is that, works as knob When being separated, it is easy to clean plate.
Knob, which can be attached, perhaps to be separated because magnetic knob system includes positioning magnet and the rotation in plate or on plate Complementary positioning magnet in button or on knob.The two magnets are configured to attract another magnet in two magnets. Therefore, they are respectively provided with different magnetic poles on its lateral surface, and in the first mode of operation, these magnetic poles are towards magnetic rotation button system Another element.If the magnetic pole towards knob of the positioning magnet of plate is south magnetic pole, the complementary of knob positions the mutual of magnet Mending magnetic pole is magnetic north pole.Complementation positioning magnet is configured as the positioning magnet of attracting board in the first mode of operation, and therefore Knob is attracted to the center predetermined of plate or plate.
It in the first mode of operation, can be by adapting to the size of such as magnet or the material or positioning magnet of magnet The distance between, to adjust the strength of attraction or attraction.Advantage may is that can relative to knob (its it is correspondingly sized and/ Or weight and/or surface properties) setting attraction, knob is reliably attached in the first mode of operation, but is directed to second Operation mode can delamination.Attraction can also be adjusted to enable knob onboard to rotate.In other words, magnet is positioned It is sufficiently strong knob to be reliably held on plate to be configured to ensure that attraction, and again weak enough so that knob can revolve Turn, but still is attached to plate.In other words, what attraction will not be strong makes knob be fixed or glue onboard.
One aspect of the present invention is the vertically moving element of knob.The vertically moving element can be for example The side of the button that can be positioned on the side of knob, the knob deviates from plate in the first mode of operation.Therefore, first Under operation mode, vertically moving element can be moved, such as by lower button (that is, towards plate).In some embodiments, Button may include more than one vertically moving element, for example, can be movable independently of one another two, three or Four moveable elements.Although this is that possible, following description will focus on a single moveable element, always It is to consider individually may be used for this always for the greater number of vertically moving element in a knob in the same manner The device and function of mobile element are unlimitedly effective.Then, each button can be for example, control the different function of equipment Energy.
Magnetic sensor circuit is configured as detecting caused by vertically moving for vertically moving element described above The change in magnetic field.In other words, when vertically moving element moved when (such as by by lower button), magnetic field is due to that can hang down The change in location of the dynamic element of translation and (such as relative to its field strength) is changed at a certain position of magnetic sensor circuit.Example Such as, if vertically moving element itself includes changing its position and therefore when vertically moving element is moved Cause changing for the magnetic field at the position (position of magnetic sensor circuit can be fixed or immovable) of magnetic sensor circuit The magnet of change can then realize this point.In another example, moving for example, leading to magnetic field when vertically moving element Shielding, so that when vertically moving element is moved, magnetic field strength at the position of magnetic sensor circuit is due to can be vertical Mobile moving for element and when becoming stronger or weaker, can also realize this point.It can be by using the quantity of reduction Sensor (such as compared with magnetic system with such as five sensors, only two sensors) provides magnetic sensor circuit. This can have the advantage that complexity reduces and at the same time cost reduces.
The advantage for detecting the movement of vertically moving element may is that another function of magnetic knob system can be detected It surveys, that is, the not only rotation of knob, and also the movement (such as pushing of the button of knob) of moveable perpendicular elements can be detected It surveys.By being detected using only magnet assembly, magnetic knob system can be it is reliable and steady because magnet is not shown Apparent degeneration or ageing process out.In some instances, in some instances it may even be possible to, for the detection vertically moved, with progress Several sensors needed for rotation detection (in rotation detection, such as needing two Hall sensors) compare, and do not need another Outer sensor or Hall sensor.
In some instances, knob can have following advantage: knob can be designed to not need energy source (such as electricity Pond).In this manner it is achieved that knob can work independently of energy source, and therefore it is sustainable, such as does not need pair This battery is charged or is replaced.In these examples, knob can be designed by only providing mechanical organ, that is, It, can be to avoid electronic component in knob.This mechanical knob can be designed separately, without providing sky for electronic component Between, this provides individually designed freedom.Only another advantage of mechanical organ, which may is that, can need only one knob to control tool There is the distinct device of magnetic system, so, mechanical organ can provide higher flexibility, reduce with complexity and cost drops It is low.
Other examples can have following advantage: magnetic knob system can work in the position separated with electronic equipment, can To adjust the electronic equipment by using magnetic knob system.In these examples, for example, plate can be the size suitable for knob Portable plate so that knob and plate are portable.This system can be by using for example may be provided in magnetic rotation button Wireless transmitter in system sends signal to electronic equipment, which includes adjustment information.This can be to using magnetic rotation button The equipment of system provides the freedom high relative to the position of magnetic knob system.
