Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1 to 5, the self-generating knob device in the present embodiment includes a knob body 100 and an electrical component 200 disposed at both sides of a panel 1. The panel 1 is a panel 1 on an electrical appliance applied to the self-generating knob device, and if the panel 1 is used on a kitchen range, the panel 1 is an upper panel 1 of the kitchen range.
The electrical component 200 includes a second magnet 10 fixedly disposed below the panel 1, a second circuit board 8 fixed below the second magnet 10, a photoelectric tube 7 electrically connected above the second circuit board 8, and a ring-shaped magnet 4 disposed at the periphery of the second magnet 10, wherein one surface of the magnet 4 is an S-pole, and the other surface is an N-pole. The magnet 4 can generate a magnetic induction line in the direction of the knob body 100.
The knob body 100 includes a housing 1, and a power generation coil 2, a first circuit board 3, a first magnet 9, a light emitting sheet, and a magnetic core 5 disposed in the housing 1. The housing 1 may also optionally be provided with functional electrical components, such as a display light, a display screen and/or operating buttons.
For convenient installation, the housing 1 comprises a bottom plate and a cover case matched and fastened with the bottom plate, and the cover case and the bottom plate are connected to form the housing 1 with an installation cavity. The first magnet 9 is fixedly arranged at the center of the bottom plate, and the first magnet 9 and the second magnet 10 are attracted with each other, so that the knob body 100 can be positioned and fixed on the panel 1.
The light emitting sheet is disposed above the first magnet 9. Reflection regions 61 capable of reflecting light perpendicularly and scattering regions 62 capable of scattering light to the outer periphery are alternately arranged on the lower surface of the light emitting sheet in the circumferential direction. In this embodiment there are two emission regions and two scattering regions 62, each occupying a 90 ° distribution space. In order to conveniently judge the rotation direction of the knob body 100, three photoelectric tubes 7 are provided in the present embodiment, three photoelectric tubes 7 are provided corresponding to the light-emitting sheets, and an included angle between two adjacent photoelectric tubes 7 relative to the center of the knob body 100 is 45 °, that is, the distribution angle of the three photoelectric tubes 7 relative to the knob body 100 is matched with the distribution angle of the reflection region 61 or the scattering region 62 on the reflection plate 6 relative to the knob body 100. In order to make the light emitted from the light emitting tube irradiate the light reflecting plate 6, the panel 1 in the present embodiment is made of a transparent plate corresponding to the region where the electrical component 200 is disposed and the bottom plate of the housing 1. The photoelectric tube 7 in this embodiment is an infrared photoelectric tube 7, and the photoelectric tube 7 can also receive light reflected by the reflective sheet. When a reflection area 61 of the reflector is arranged right above the photoelectric tube 7, the reflection area 61 vertically reflects infrared light, the photoelectric tube 7 receives the infrared light vertically reflected by the reflector, the second circuit board 8 detects an optical signal fed back by the photoelectric tube 7, and a signal is set to be 0; when the scattering area 62 is located above the photoelectric tube 7, the infrared light is scattered around, the photoelectric tube 7 cannot receive the infrared light, the second circuit board 8 cannot detect the optical signal fed back by the photoelectric tube 7, and the signal is set to 1. The signals of the three photoelectric tubes 7 jointly form a signal code. When the knob body 100 rotates by an angle of 45 degrees, the code of the signal received by the three photoelectric tubes 7 changes once. Assuming that the initial code is 001, when the knob body 100 rotates clockwise, the signal codes sequentially change according to the following rules: 001 → 100 → 110 → 011 → 001, cyclic variation. When the knob body 100 rotates anticlockwise, the signal change rule is just opposite. Thus, the rotation direction of the knob body 100 can be judged, and the rotation angle of the knob body 100 can be obtained. And the second circuit board 8 is adjusted according to the rotation direction and the rotation angle of the knob body 100. In order to obtain a more precise rotation angle, more emitting areas, reflecting areas 61 and more photoelectric cells 7 can be arranged for detection calculation.
The magnetic core 5 has a magnetic gathering function, the magnetic core 5 in the embodiment is annular and is arranged on the periphery of the first magnet 9, the generating coil 2 is attached to the lower surface of the magnetic core 5, and the magnetic core 5 can enhance the magnetic flux of the generating coil 2, so that the self-generating capacity is increased. The diameter of the core 5 matches the diameter of the magnet 4. The power generation coil 2 in this embodiment is annular as a whole and covers the lower surface of the magnetic core 5. The generating coil 2 includes a first electrode 21 having a ring shape, a second electrode 22 disposed on the outer periphery of the first electrode 21 and having a ring shape, and a plurality of wires 23 connected between the first electrode 21 and the second electrode 22 in the radial direction, and the wires 23 are uniformly distributed in the circumferential direction. The structure of the generating coil 2 greatly facilitates the connection between the first circuit board 3 and the generating coil 2, and the wire for connecting the first circuit board 3 and the generating coil 2 can be connected at any position of the first electrode 21 and the second electrode 22.
In the process that the generating coil 2 rotates along with the knob body 100, all the wires 23 are matched with the magnetic induction lines to move, the directions of the cutting magnetic induction lines are the same, the same induced electromotive force is generated, self-generation is achieved, and the self-generation is output to the first circuit board 3 through the electrodes. The structure of the generating coil 2 ensures that all the leads 23 have the same direction relative to the center of the knob body 100 and the same direction of the induced electromotive force generated by the leads when the knob body 100 rotates, and compared with the existing coil which is generally in a circular winding structure and causes the problem that the generation efficiency is reduced because the magnetic induction lines are led out inevitably when the magnetic induction lines flow in, the generating coil enhances the generation efficiency.
The first circuit board 3 in this embodiment is electrically connected to the first electrode 21 and the second electrode 22, and further receives electrical energy for the device to work. In order to facilitate the use, the first circuit board 3 is further electrically connected with an electricity storage unit, and the first electrode 21 and the second electrode 22 are connected to the electricity storage unit through an electric energy conversion circuit, so that the electric energy generated by the self-electricity generation is stored in the electricity storage unit. The electrical components electrically connected to the first circuit board 3 are operated under the power supply of the energy storage unit.
The self-generating knob device realizes self-generation by utilizing the magnet 4 and the generating coil 2, and further provides electric energy for the knob body 100, so that when some electric devices with small power supply are arranged on the knob body 100, no additional power supply is needed to be installed, and the electric quantity of the self-generating electricity is enough to provide the electric devices for working. The knob body 100 does not need to be charged during use, thereby improving the convenience of use. The knob body 100 can be correspondingly prolonged in service life without being disassembled or assembled.
