Embodiment
For further setting forth the technological means and effect thereof that the utility model takes, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Refer to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of contactless magnetic induction rotary switch, described contactless magnetic induction rotary switch comprises: several magnet 5 be fixed on rotating disk 4, the rotating shaft 6 fixed with described rotating disk 4 center, be fixed on circuit board 1 below described rotating disk 4, and described circuit board 1 is provided with several magnetic force induction device 2 in the region close with described rotating disk 4 edge.
Described magnet 5 has multiple, is distributed in the edge of described rotating disk 4 uniformly, and in present embodiment, preferably 3, the distance between two often adjacent magnet 5 is the length of 1/3rd circumference.
Wherein, the center of described rotating disk 4 is provided with fixing hole 41, and this rotating shaft 6 through described fixing hole 41, and is clamped on described fixing hole 41 by snap ring 7 by described rotating shaft 6, prevents described rotating shaft 6 from coming off from described fixing hole 41.
Wherein magnetic force induction device 2 is for detecting the magnetic field at described rotating disk 4 edge and output signal.The change of the angle that this concrete magnetic force induction device 2 rotates according to rotating disk 4 can detect different magnetic field intensity, and exports the signal of different amplitude, and this signal is sent to described circuit board 1.
Described circuit board 1 is for receiving described magnetic force induction device 2 signal and producing switch controlling signal.In the present embodiment, described circuit board 1 must have the control circuit making Logic judgment according to magnetic force induction device 2 signal received, make logic control, thus realize the controlling functions of switch.
Further, described rotating shaft 6 is through the shell 3 of the equipment of required control, and described circuit board 1 is fixed on described shell 3.
Further, the other end of described rotating shaft 6 is also provided with adjustment knob 8, and described adjustment knob 8 drives described rotating shaft 6 to rotate by external force.
When using this magnetic induction rotary switch, user is by the described adjustment knob 8 of twisting, and driven rotary axle 6 and rotating disk 4 rotate, thus change the magnetic field intensity around described magnetic force induction device 2, thus control judgement made by the described circuit board 1 that sets out.
Wherein, reformed magnetic field intensity not only comprises the change of the size of electromagnetic quantities, also comprises the change in the direction in magnetic field, and such as the south poles in the magnetic field be positioned at directly over circuit board 1 is reversed after rotating by rotating disk 4.
Further, described magnetic force induction device 2 has multiple, in present embodiment preferably 4.This magnetic force induction device 2 is uniformly distributed on the circuit board 1 below described rotating disk 4.
In the present embodiment, comprehensive descision can be made by the measurement of different inductors 2 arranging multiple magnetic force induction device 2 on the circuit card 1, thus reduce the probability of described circuit board 1 erroneous judgement, contribute to improving precision.
