technical field

The present invention generally relates to a switchgear.

Background technique

There are various types of existing switch devices, including physical manually operated switches such as buttons, rockers or touch switches, sensor-controlled switches such as voice-controlled switches, temperature-controlled switches, etc., and time-controlled switches, and the like.

For some applications, such as a magnetic levitation globe with a built-in light bulb or a magnetic levitation speaker, since the suspension is usually accompanied by rotational motion during the suspension process, it is very inconvenient to operate the physical power supply switch provided on it. If a conventional sensor-controlled switch such as a voice-controlled switch is used, it is not only susceptible to environmental noise interference, but also has basically no novel operating experience.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a novel switching device for electrical appliances.

According to a first aspect of the present invention, a suspension switch device is provided, comprising:

switch suspension, with magnet;

Magnetic suspension support mechanism, used to support the switch suspension body in a stable suspension state relative to it;

a magnetic detector for detecting the change of the magnetic field of the switch suspension relative to it and outputting a corresponding magnetic change signal; and

The switch control circuit receives the magnetic change signal output by the magnetic detector, and generates a corresponding switch signal based on the received magnetic change signal.

According to the present invention, the switch control circuit generates a corresponding switch signal only when the magnetic change signal output by the magnetic detector exceeds the set value. The set value is greater than the disturbance value corresponding to the normal and stable suspension of the switch suspension. In other words, in the absence of artificial interference, when the switch suspension itself is disturbed by the normal air environment, the magnetic change signal or field strength signal detected and output by the magnetic detector is smaller than the above set value. When forced interference is applied to the switch suspension that is in a normal and stable suspension state or roughly suspended at the reference position, for example, by simply pressing or pushing the switch suspension to a suitable distance, such as 1-2mm, then the magnetic detector detects and outputs The magnetic change signal will be greater than or exceed the set value. This level of pushing usually does not exceed or destroy the self-balancing recovery or adjustment capability of the magnetic levitation system consisting of the switch suspension and the magnetic levitation support mechanism.

According to the suspension switch device of the present invention, the magnetic detector is preferably used to detect the change of the magnetic field when the switch suspension moves far and near relative to it. This far-near movement, or a change in the distance of both along the Z-axis, can be achieved by manually pressing the switch suspension toward the magnetic detector (or magnetic suspension support mechanism). This manual pressing simulates the manual operating experience of a conventional switch.

In addition, the magnetic detector of the present invention can also be used to detect the change of the magnetic field when the switch suspension body moves in parallel with it, and the parallel movement is also realized by toggling the switch suspension body back and forth or left and right. The magnetic field change during parallel movement can include X-axis and Y-axis magnetic field changes. In this case, the magnetic change signal output by the magnetic detector may include at least one vector signal along the X-axis, Y-axis and Z-axis directions, and the switch control circuit generates a corresponding mode of switch control signal based on each vector signal.

Corresponding currents are controlled to flow through the electromagnetic coils to return the permanent magnets of the switch suspension to their relative suspension equilibrium positions, wherein the magnetic sensor components of the magnetic suspension support mechanism double as a magnetic detector.

As an alternative embodiment, the magnetic suspension support mechanism and the switch suspension can form a magnetic suspension system, for example, the switch suspension can be stably suspended at a predetermined reference position below the magnetic suspension support mechanism. In this case, the magnet of the switch suspension body can also be a permanent magnet with opposite magnetic poles, the magnetic suspension support mechanism has a ferromagnetic element, an electromagnetic coil and a magnetic sensor, and the ferromagnetic element and the permanent magnet of the switch suspension body form a basic attractive force balance magnetic field (usually with vertical or vertical degrees of freedom), the magnetic sensor is used to detect the floating balance position offset between the ferromagnetic element and the permanent magnet of the switch suspension in real time, and the electromagnetic coil is based on the floating balance position offset detected by the magnetic sensor assembly. Corresponding currents are controlled to flow through the electromagnetic coils to return the permanent magnets of the switching suspensions to their relative suspension equilibrium positions, wherein the magnetic sensors of the magnetic suspension support mechanism double as magnetic detectors.

It should be understood by those skilled in the art that the working mode of the magnetic suspension device of the present invention is not important, as long as the suspension body contains magnets or has magnetism, so that the magnetic field change caused by the positional deviation of the suspension body can be easily Detected by magnetic detectors or Hall sensors.

According to the present invention, the suspension can be designed in any desired configuration, such as a suitably sized rubber or lighter or a globe or a toy or the like. Alternatively, the suspension itself can be designed as a sphere with opposite poles. In the present invention, the term "opposite magnetic poles" means that the N and S poles of the magnet are on the same straight line; the term "magnet" includes permanent magnets and electromagnets; the term "ferromagnetic element" means made of iron or permanent magnets, etc. The resulting element can be attracted by other magnets.

detailed description

The present invention will be further described below with reference to the embodiments and the accompanying drawings. Those skilled in the art should understand that the embodiments and the accompanying drawings are only for better understanding of the present invention and are not intended to make any limitation.

1 shows an electrical appliance according to a first embodiment of the present invention, wherein the bottom of the base or bracket A is provided with an electrical device B, such as a light bulb, and a circuit board 30, and the circuit board 30 is provided with a power supply for controlling the electrical device B to be turned on or off. Cut off switch control circuit.

The top of the bracket A is provided with a magnetic suspension support mechanism 10 . The magnetic suspension support mechanism 10 includes an iron core 11 and an electromagnetic coil 12 arranged around the iron core. A magnetic sensor (for example, a Hall sensor) 13 is provided at the lower end of the iron core 11 . The spherical suspension 20 is provided with cylindrical magnets 21 with opposite poles. Of course, U-shaped magnets can also be used in this case.

A magnetic attraction force will be generated between the magnet 21 of the suspension body 20 and the iron core 11. When the distance between the two is adjusted to an appropriate size (predetermined distance), the gravity of the suspension body 20 will be balanced by the magnetic attraction force, so that it will be supported relative to the magnetic suspension. The mechanism 10 or the iron core 11 is in a suspended equilibrium position. Once the distance between the magnet 21 of the suspension body 20 and the iron core 11 changes due to air disturbance or the like, the suspension balance of the suspension body 20 relative to the magnetic suspension support mechanism 10 will be broken. The sensor 13 detects the longitudinal (vertical) position change of the suspension 20 relative to the iron core 11 in real time and generates a corresponding signal, which is sent to a controller such as a control chip (not shown in detail) provided on the magnetic levitation support mechanism 10 . The controller controls the magnitude and direction of the current flowing in the electromagnetic coil 12 according to the position signal transmitted by the sensor 13, so that the electromagnetic coil 12 generates a corresponding electromagnetic force, which acts on the magnet 21 of the suspension body 20 to return it to the suspension equilibrium position. The structure and working principle of this magnetic suspension device can also be found in CN2561163Y, the entire contents of which are incorporated herein by reference.

Of course, in this magnetic levitation structure or system, the electromagnetic coil 12 is not limited to being arranged around the iron core 11, and it can also be arranged at the bottom of the bracket A so as to be located below the suspension body 20 during suspension; the suspension body 20 is not limited to It is spherical, and its magnet 21 is not limited to a cylindrical shape. For example, the entire suspension 20 can be a magnet with opposite magnetic poles (the up and down directions are shown in the figure); It can be arranged in any suitable location such as on the bottom of the bracket A.

In the embodiment shown in FIG. 1 , the sensor 13 also serves as a magnetic detector, although other magnetic sensors can also be provided separately or additionally to serve as the magnetic detector. The sensor 13 in the magnetic suspension system shown in FIG. 1 is usually a vertical component Hall sensor, so as to detect the change of the vertical magnetic field component. The vertical component field strength signal generated by the sensor 13 will be transmitted to the switch control circuit on the circuit board 30 through the transmission line 14 . After receiving the above-mentioned vertical component field strength signal exceeding the set value, the switch control circuit will generate a corresponding switch signal to cut off or switch on the power supply of the electrical device B, for example, when the suspension is gently pressed down or pushed up by hand 20. Make it vertically deviate from the suspension equilibrium position by a certain distance such as 1-2mm without exceeding the self-balancing capability of the device (that is, the suspension body will still return to its suspension equilibrium position after the hand is released). In this way, the power supply control to the electrical device B can be realized by manually operating the suspension body 20 .

2 shows an electrical appliance according to a second embodiment of the present invention, wherein the magnetic levitation support mechanism 10 is provided with an electrical device B such as a light bulb and a circuit board 30 , and the circuit board 30 is provided with a switch for controlling the power of the electrical device B to be turned on or off Control circuit.

The magnetic suspension support mechanism 10 is further provided with an iron core 11 and an electromagnetic coil 12 arranged around the iron core. A ring magnet 15 is arranged on the periphery of the electromagnetic coil 12 . A magnetic sensor or Hall sensor 13 is provided in the center of the ring magnet 15 . The spherical suspension 20 is provided with cylindrical magnets 21 with opposite poles.

A magnetic repulsion force will be generated between the magnet 21 of the suspension body 20 and the ring magnet 15. When the distance between the two is adjusted to a suitable size (predetermined distance), the gravity of the suspension body 20 will be balanced by the magnetic repulsion force, so that the magnetic suspension will be relative to the magnetic suspension. The support mechanism 10 or the ring magnet 15 is in a floating equilibrium position. The magnets 21 and the ring magnets 15 may adopt the adjacent matching method of the opposite poles of the small diameter cylindrical magnet and the large diameter ring magnet as shown, or the adjacent matching method of the same magnetic poles of two substantially equal diameter ring magnets. Once the distance between the magnet 21 of the suspension body 20 and the ring magnet 15 changes due to air disturbance or the like, the suspension balance of the suspension body 20 relative to the magnetic suspension support mechanism 10 will be broken. The sensor 13 detects in real time the position change of the magnet 21 of the suspension body 20 relative to the lateral direction (the horizontal direction is shown in the figure) of the ring magnet 15 and generates a corresponding signal, which is transmitted to the controller provided on the magnetic suspension support mechanism 10, such as a control chip (not shown in detail). . The controller controls the magnitude and direction of the current flowing in the electromagnetic coil 12 according to the position signal transmitted by the sensor 13, so that the electromagnetic coil 12 and its reinforcing iron core 11 generate corresponding electromagnetic force, which acts on the magnet 21 of the suspension body 20 to make It returns to the suspended equilibrium position. The structure and working principle of the magnetic repulsion type suspension device can also be found in, for example, the applicant's previous patents CN100544183C and CN105790641B, the entire contents of which are incorporated herein by reference.

In the embodiment of the magnetic repulsion type suspension system in FIG. 2 , the sensor 13 is usually a sensor component composed or integrated of a horizontal component Hall sensor and a vertical component Hall sensor. As shown in Figure 3, the horizontal component Hall sensor includes an X-axis sensor and a Y-axis sensor, and the vertical component Hall sensor is a Z-axis sensor. For example, when the electrical device B is a Bluetooth speaker, its vertical component Hall sensor or Z-axis sensor can be used to generate the main switch mode vector signal, the X-axis sensor can be used to generate the volume switch mode vector signal, and the Y-axis sensor can be selected. Used to generate the vector signal of the selection switch mode. The same view of an embodiment as a switch mode vector signal ^{^{(X +, X -, Y}} +, Y -, Z + or Z ^-) sensor 13 produced in FIG. 1 transmits 14 to switch on the circuit board 30 is controlled by the transmission line circuit. The switch control circuit will generate a corresponding switch control signal based on the received switch mode vector signal to control the operation mode of the electrical device B. Of course, only the Z-axis sensor can also be used to simply generate the switch signal.

FIG. 4 shows the electrical appliance of the third embodiment of the present invention, which is similar to the second embodiment, except that the electrical device B (illustrated as a light bulb) provided with the magnetic suspension support mechanism 10 is moved to the suspension body 20 middle.

In FIG. 4 , the suspension body 20 is further provided with a power wireless receiving coil 26 , and the power wireless receiving coil 26 is connected to the rectifier circuit board 25 to supply power to the electrical device B. As shown in FIG. The magnetic levitation support mechanism 10 is correspondingly provided with a power wireless transmitting coil 16 , and the switch circuit board 30 is used to control the power supply to the power wireless transmitting coil 16 . When the power wireless transmitting coil 16 is energized, a corresponding current can be generated in the power wireless receiving coil 26. This wireless power supply structure belongs to the conventional design in the art, and its working principle will not be described in detail here. In this way, the switch mode switching of the electrical device B or the indicator light therein can be realized by manual operation such as light pressure on the suspension body 20 as described above.

FIG. 5 shows a block schematic diagram of the switching circuit of the present invention. As shown in the figure, the sensor 13 further amplifies the detected corresponding magnetic field strength signal through the signal amplifier 19 and transmits it to the switch control circuit on the circuit board 30, and the switch control circuit can then generate the corresponding switch control signal to control the power consumption device B. Carry out the corresponding power supply control or mode switching.

Of course, the signal amplifier 19 can also be omitted or the original signal amplifier on the magnetic levitation support mechanism 10 can be used as the same. In this case, the suspension switch device of the present invention can be formed by using the self-balancing adjustment capability of the magnetic suspension system and its own sensor and signal amplifier, and connecting the corresponding switch circuit without adding any components including the return spring.

Although the suspension body 20 is designed as a spherical shape, those skilled in the art will understand that it can be designed into any desired configuration such as a suitable size rubber or lighter or a globe or a toy, etc. as required.

The annular wall light R shown in FIG. 6 can pivot up and down relative to the magnetic suspension support mechanism 10 . The suspension body 20 is suspended on the side of the magnetic levitation support mechanism 10 away from the wall, and can freely pass through or pass through the annular wall lamp R during the folding or pivoting process of the annular wall lamp R without interfering with it. This wall light is incredibly novel and easy to use.
