Description

Quasi-suspension switch device

Technical Field

The present invention generally relates to a switchgear.

Background

There are various switch devices, including physical manual switches such as keys, rocker or touch switches, etc., sensing switches such as voice-operated switches, temperature-controlled switches, etc., and time-controlled switches.

CN112086312A discloses a suspension switch, which obtains a corresponding switch signal by manually operating a switch suspension body in a fully suspended state, so as to obtain a novel and convenient switch operation experience; the entire contents of which are incorporated herein by reference. However, the operation of such a float switch requires a certain level of skill, and the floating state of the switch float is easily damaged. In addition, the overall structure of the suspension switch is relatively complex, resulting in high cost.

Disclosure of Invention

It is an object of the present invention to provide a novel switching device which is easy to operate.

According to a first aspect of the present invention, there is provided a switching apparatus comprising:

a fixed base body having a first permanent magnet structure;

a movable operation switch member having a second permanent magnet structure; and

and the retaining piece is used for normally placing the switch piece at the set quasi-suspension position relative to the base body, allowing the switch piece to be manually operated relative to the base body within the set operation range, and after the manual operation is released or relieved, the switch piece can be automatically reset to the set quasi-suspension position by virtue of the magnetic field force formed by the first permanent magnet structure body and the second permanent magnet structure body.

In the invention, the quasi-suspension means that the switch piece has a visual suspension effect relative to the fixed seat body through the auxiliary deviation rectifying effect of the holding piece.

According to the switchgear of the present invention, the gravity of the switching piece is offset by the magnetic field force formed by the first permanent magnet structure and the second permanent magnet structure, thereby enhancing the visual levitation effect.

According to one embodiment of the switching installation according to the invention, the holding element is connected on the one hand to the stationary base body and on the other hand is in contact with the switching element and thus assists the switching element in balancing in the set quasi-floating position. Of course, the holding member is not limited to be connected to the fixed base body, as long as it can contact with the switch member and perform the function of assisting the correction.

According to the above embodiment of the present invention, when the switch member is in the set quasi-floating position relative to the seat body, the acting force between the retaining member and the switch member may be substantially zero or no specific biasing acting force exists. In this case, the frictional resistance to which the switch member is manually operated is minimized.

In order to achieve substantially zero force between the holding member and the switching member, the first permanent magnet structure may be a ring-shaped magnet or a plurality of magnetic blocks arranged in a ring shape, and the second permanent magnet structure may be a magnetic bead (e.g., a magnetic sphere) or a magnetic column (e.g., a cylindrical magnet) having magnetic centrosymmetric axes substantially coincident and having the same magnetic pole direction. Of course, the first and second permanent magnet structures may also take other configurations and/or arrangements to achieve this zero force effect.

According to the above embodiment of the present invention, when the switch member is in the set quasi-floating position relative to the seat body, the holding member and the switch member may have or form a bias force therebetween. In this case, it is only necessary to provide the holder in a specific orientation (it is not necessary to provide it around the switch member), so that the holder can be reduced to further enhance the floating visual effect.

In order to realize the bias acting force between the holding member and the switch member, the first permanent magnet structure body may be a ring-shaped magnet or a plurality of magnetic blocks arranged in a ring shape, and the second permanent magnet structure body may be a magnetic bead (e.g. a magnetic ball) or a magnetic column (e.g. a cylindrical magnet) having magnetic central symmetry axes which are staggered with each other and have the same magnetic pole direction. Of course, the first and second permanent magnet structures may take other configurations and/or arrangements to achieve this biasing force effect.

According to the above embodiment of the present invention, the holder may be a rigid member, and the switch member may be slidably contacted with the holder in a form-fitting manner. In this case, the retaining member may be a retaining ring or a retaining cylinder, in whole or in part, extending from the stationary housing.

According to the above-described embodiments of the present invention, the holding member may be a deformable member such as a flexible string or a wire sheet, etc., connected to the opening and closing member. This form of retainer is more concealable, enabling further enhancement of the visual suspension effect.

The switch device according to the present invention may further comprise a signal generating means disposed in the fixed base, for generating a corresponding switch signal by the movement of the switch member relative to the fixed base.

The signal generating device can be a magnetic sensor, and generates a corresponding switching signal by detecting the change of the magnetic field of the second permanent magnet structural body of the switching piece relative to the signal generating device. The signal generating device may also be an electromagnetic coil, and the current signal generated in the second permanent magnet structural body of the switching element by the movement relative thereto serves as the corresponding switching signal. Of course, the signal generating means may be other mechanical structures for switching on or off the circuit in response to the operation of the switching element.

According to a second aspect of the present invention, there is also provided an electrical appliance comprising a power consuming component and the above-mentioned switching device, wherein the switching device is configured to control a switching mode of the power consuming component.

The signal generating device of the switch device and the power consumption component can be connected in a wired mode or in a wireless mode.

According to the quasi-levitation switch device, the high-cost levitation control system is omitted, the visual levitation effect can be achieved, and the operability is greatly improved.

Detailed Description

The present invention is further described below in conjunction with the following examples and figures, which are to be understood by those skilled in the art as being solely for the purpose of better understanding the present invention and not for the purpose of limiting same.

Fig. 1 shows an embodiment of the electrical appliance according to the invention with power consuming components 80 and a switching device. The power consuming component 80 may be, for example, a lamp, a sound box, or the like. The switchgear comprises a stationary body 100, a movably operated switching element 20 and a holding element 30 for holding the switching element 20 in a set quasi-floating position with respect to the body 100.

The ring magnet 10 is fixed to the fixed base 100, and the holder 30 in the form of a cylinder is fixed to the ring magnet 10 or the fixed base 100. The switching element 20 in the form of a magnetic ball is held on top of the holder 30 with its magnetic central symmetry axis substantially coinciding with the magnetic central symmetry axis of the ring magnet 10 and with the same magnetic pole direction, i.e. the lower magnetic pole of the illustrated switching element 20 and the lower magnetic pole of the ring magnet 10 are both N and the upper magnetic pole is both S. By means of the magnet arrangement, the switch member 20 can be quasi-suspended at a set position above the ring magnet 10 or the fixed base 100. That is, the illustrated trend of the up-and-down movement and the trend of the flip-over movement of the switching member 20 with respect to the ring magnet 10 are completely eliminated, and the trend of the horizontal movement (random disturbance) of substantially zero is completely eliminated by the retainer 30 which is in surrounding contact therewith. If the switch member 20 is pressed downward, the switch member 20 will automatically rebound or return to the set quasi-floating position at the top of the holder 30 under the force of the magnetic field after releasing the hand.

A magnetic sensor or hall sensor 40 is also provided in the operating movement path of the switch member 20. The hall sensor 40 is fixed to a suitable position of the stationary base 100, for example, in a central hole of the ring magnet 10, and is connected to the switching signal circuit board 50. The magnetic field intensity of the manually operated switching member 20 relative to the hall sensor 40 changes after the manually operated switching member moves downward, and the hall sensor 40 generates a corresponding switching signal by detecting the change of the magnetic field intensity of the switching member 20.

The illustrated power consuming component 80 is also secured to the stationary housing 100 and is connected to the control circuit board 70. The switching signal circuit board 50 and the control circuit board 70 are connected by an electric wire 60. Thus, according to the position change of the switching element 20 after being manually operated, the hall sensor 40 generates a corresponding switching signal, and the switching signal is transmitted to the control circuit board 70 of the power consuming element 80 through the switching signal circuit board 50, thereby realizing the control of the switching mode of the power consuming element 80.

The embodiment shown in fig. 2 is a variation of the embodiment shown in fig. 1, wherein the switch member 20 takes the form of a cylindrical magnet and the holder member 30 takes the form of a horn.

The embodiment of fig. 3 is another variation of the embodiment of fig. 1 in which the switching element 20 is in the form of a magnetic ball and the retaining element 30 is in the form of a flared cylinder to facilitate positioning of the switching element 20 for manipulation. In addition, the ring magnet 10 is positioned to be raised from the stationary base 100 with a center height substantially the same as that of the switching element 20 or the magnetic ball. This variant allows the up-and-down offset operation of the shutter 20 to be reset equally quickly after releasing the hand.

The embodiment shown in fig. 4 is a simple variant of the embodiment shown in fig. 3, in which the switch member 20 takes the form of a cylindrical magnet.

The embodiment shown in fig. 5 is a further variant of the embodiment shown in fig. 1, in which the power consuming components 80 are not fixed to the same fixed body 100 as the switchgear, but in a more flexible and separate form. Fig. 5 employs an electromagnetic coil 41 in place of the hall sensor 40 to generate a corresponding current signal in the electromagnetic coil 41 when the switch member 20 is moved vertically relative to the electromagnetic coil 41, and a wireless signal transmitter 51 connected to the electromagnetic coil 41 to wirelessly transmit the current signal therein to a wireless signal receiver 61 connected to the control circuit board 70. The control circuit board 70 controls the power switching mode of the power consuming component 80 based on the signal received by the wireless signal receiver 61. The external power plug 90 provides an external power supply for the power consuming device 80.

The embodiment of fig. 6 is a variation of the embodiment of fig. 5 in which the switch member 20 takes the form of a cylindrical magnet and the holder member 30 takes the form of a horn.

Fig. 7 shows a biasing structural variation of the switching device used in the embodiment shown in fig. 1, in which the switching element 20 in the form of a magnetic ball is held on top of the holding element 30 in the form of an arc segment, with its magnetic central symmetry axis being offset from the magnetic central symmetry axis of the ring magnet 10, i.e. the magnetic central symmetry axis of the switching element 20 is shown as being offset to the holding element 30 side from the magnetic central symmetry axis of the ring magnet 10. In this magnet arrangement, the switching element 20 is only offset in the horizontal direction towards the holding element 30, so that the holding element 30 need not be arranged around the entire cylinder of the switching element 20, but rather only over a corresponding arc or even a supporting point. This makes the floating visual effect more realistic.

Fig. 8 shows a corresponding variant of the switching device used in the embodiment shown in fig. 5, similar to fig. 7, in which the switching element 20 is likewise arranged eccentrically with respect to the ring magnet 10.

Fig. 9 shows a similar arrangement to fig. 7, except that a deformable retaining member 31 in the form of a wire is used to achieve an eccentric arrangement of the switch member 20 relative to the ring magnet 10. The deformable retaining member 31 may take any suitable form fixedly disposed relative to the ring magnet 10 and connected to the switching element 20, such as a flexible cord or a somewhat resilient wire, etc. This variation may lead to better suspension vision in certain applications.

Fig. 10 shows a corresponding variant of the switching device used in the embodiment shown in fig. 5, similar to fig. 9, in which the switching element 20 is likewise arranged eccentrically with respect to the ring magnet 10.

Further variations on the above embodiments are possible, for example, the ring magnet 10 is not limited to the illustrated single circular magnet ring form, but may take any other suitable form, such as a ring or diamond arrangement of a plurality of magnetic blocks.
