The transmission between each channel is not interfered with each other, and the implementation principle is analyzed below.
Applying an alternating current I to the transmitting terminal P When the resonance angular frequency omega is higher than the resonance angular frequency I, the transmitting end current I is transmitted to the closed coil (receiving coil) to generate an induced electromotive force U according to the Lenz law when the total magnetic field intensity is not 0 P Under the fixed condition, the induced electromotive force is in direct proportion to the mutual inductance M, the mutual inductance M is determined by the characteristics of the two energy coils, and under the conditions that the relative angle of the two energy coils is fixed and the central distance is not changed, the value of the mutual inductance M is still unchanged, namely the induced electromotive force is unchanged, so that stable energy can be picked up at any angle.
U＝jωMI p (1)
Firstly, analyzing the application of alternating current I to the first path of transmitting coil P1 And the other 7 coils are influenced by the first path of transmitting coil, and because the winding method of each group of transmitting coil is consistent with that of the receiving coil, the method can be analogized by only analyzing the influence among the transmitting coils. As shown in fig. 6, the first path of transmitting coil and the second path of transmitting coil are overlapped at an angle of 90 ° in a crossing manner, and both the first path of transmitting coil and the second path of transmitting coil are wound in an 8-shaped manner. Taking the first path of transmitting coil as an example, an alternating current I is applied to the first path of transmitting coil P1 When the magnetic field is applied, the left part and the right part generate an alternating magnetic field with consistent strength and opposite directions; receiving the magnetic field of the first path of transmitting coilThe magnetic field intensity is 0 within the range of the upper half part of the second path of transmitting coil. In the same way, the alternating magnetic field intensity of the first transmitting coil in the lower half range of the second transmitting coil is 0, the two are still 0 in addition, that is, the mutual inductance M is 0, the induced electromotive force is 0, which indicates that the interference of the first transmitting coil to the second transmitting coil is 0, and the analysis condition of the receiving end in the same way is similar, and the interference of the first transmitting coil to the second receiving coil is also 0.
In conclusion, the first path of transmitting coil has no interference to the second path of coil (transmitting coil and receiving coil).
Similarly, the first transmitting coil applies an alternating current I P1 Meanwhile, the magnetic field interference on the third transmitting coil is as shown in fig. 7, the range of the third transmitting coil is interfered by the magnetic fields with the same strength and opposite directions of the left part and the right part generated by the first transmitting coil, the comprehensive magnetic field strength is 0, the mutual inductance M is 0, the induced electromotive force U is 0, the analysis conditions of the receiving end are similar in the same way, and the interference of the first transmitting coil on the third receiving coil is also 0.
In conclusion, the first path of transmitting coil has no interference to the third path of coil (transmitting coil and receiving coil).
As shown in FIG. 8, a current I is applied to the first transmitting coil p1 The rear left part generates a magnetic field with a downward direction, the right part generates a magnetic field with an upward direction, and the magnetic field intensity of the two parts is consistent. The double 8-shaped coils are influenced by the 8-shaped coil magnetic field to induce corresponding current I p1-1 、I p1-2 、I p1-3 、I p1-4 And the currents are equal in magnitude. According to lenz's law, the double 8-shaped coil generates an upward magnetic field at the upper left part, a downward magnetic field at the upper right part, an upward magnetic field at the lower left part and a downward magnetic field at the lower right part. Due to the special winding mode of the double 8-shaped coil I p1-1 And I p1-4 Reverse direction, I p1-2 And I p1-3 And reversing the direction. It can be easily known from the tracking along the winding direction that the induced current of the double 8-shaped coils is 0 in total, i.e. the interference of the 8-shaped coils to the double 8-shaped coils is 0 (induced voltage)Is 0). Similarly, the receiving end has a similar analysis condition, and the interference of the first transmitting coil to the fourth receiving coil is also 0.
In conclusion, the first path of transmitting coil has no interference to the fourth path of coil (transmitting coil and receiving coil).
Because the winding mode of the second path of coil is the same as that of the first path of coil, the second path of coil and the first path of coil are placed at 90 degrees, the analysis mode is similar, and the description is omitted here.
Similarly, after the second path of coil is loaded with current, no magnetic field interference exists on other coils.
As shown in FIG. 9, the third transmitter coil applies an alternating current I P3 When the magnetic field of the first path of transmitting coil is influenced by the magnetic field of the second path of signal coil, according to Lenz's law, the left half part of the first path of transmitting coil generates a magnetic field with an upward direction, namely generates a current I in a counterclockwise direction P3-1 (ii) a Similarly, the right half of the first transmitting coil generates a magnetic field in an upward direction, i.e. generates a current I in a counterclockwise direction P3-2 The induced currents of the two parts are equal in magnitude. Since the first path of transmitting coil is reversely wound, when viewed along the winding direction of the first path of transmitting coil, I P3-1 And I P3-2 The directions are opposite, that is, the total induced electromotive force is 0, so that the interference voltage of the third path of transmitting coil to the first path of transmitting coil can be considered as 0. Similarly, the receiving end has a similar analysis condition, and the interference of the third transmitting coil to the first receiving coil is also 0.
In conclusion, the third path of transmitting coil has no interference to the first path of coil (transmitting coil and receiving coil).
As shown in FIG. 10, the third transmitting coil applies an alternating current I P3 When the first path of transmitting coil is influenced by the magnetic field of the second path of transmitting coil, according to Lenz's law, the upper half part of the first path of transmitting coil generates a magnetic field in an upward direction, i.e. generates a current I in a counterclockwise direction P3-3 (ii) a Similarly, the lower half part of the second transmitting coil generates a magnetic field in an upward direction, namely, generates a current I in a counterclockwise direction P3-4 The induced currents of the two parts are equal in magnitude. The second transmitting coil is reversely wound, so that the second transmitting coil is smoothly woundViewed in the direction of winding of the second path of the transmitting coil, I P3-3 And I P3-4 The directions are opposite, that is, the total induced electromotive force is 0, so that the interference voltage of the third path transmitting coil to the second path transmitting coil can be considered to be 0. Similarly, the receiving end has a similar analysis condition, and the interference of the third transmitting coil to the second receiving coil is also 0.
In conclusion, the third path of transmitting coil has no interference to the second path of coil (transmitting coil and receiving coil).
As shown in fig. 11, a current I is applied to the third transmitting coil p3 A downward-directed magnetic field is then generated. The double 8-shaped coils are induced to generate corresponding current I under the influence of the 8-shaped coil magnetic field P3-5 、I P3-6 、I P3-7 、I P3-8 And the currents are equal in magnitude. According to lenz's law, the double 8-shaped coil generates an upward magnetic field in all four parts. Due to the special winding mode of the double 8-shaped coil I P3-5 And I P3-6 Reverse direction, I P3-7 And I P3-8 And reversing. It is easy to know from the tracking along the winding direction that the sum of the induced currents of the double 8-shaped coils is 0, i.e. the interference of the 8-shaped coils to the double 8-shaped coils is 0 (the induced voltage is 0). Similarly, the interference of the third transmitting coil to the fourth receiving coil is also 0.
In conclusion, the third path of transmitting coil has no interference to the fourth path of coil (transmitting coil and receiving coil).
Applying an alternating current I to a fourth transmitting coil P4 Meanwhile, the magnetic field interference on the first path of transmitting coil is as shown in fig. 12, the magnetic field interference with the same strength and opposite directions on the upper and lower parts generated by the fourth path of transmitting coil is received in the left half range of the first path of transmitting coil, and comprehensively, the magnetic field strength is 0 in the left half range of the first path of transmitting coil; in a similar way, the magnetic field intensity in the right half range of the first path of transmitting coil is 0. According to the analysis, the first path of transmitting coil is not interfered by the magnetic field of the fourth path of transmitting coil, namely, the two coils are decoupled with each other. Similarly, the receiving end has a similar analysis condition, and the interference of the fourth transmitting coil to the first receiving coil is also 0.
In conclusion, the fourth transmitting coil has no interference to the first coil (the transmitting coil and the receiving coil).
The influence of the fourth transmitting coil on the second transmitting coil after applying current is similar to the influence of the fourth transmitting coil on the first transmitting coil, and the fourth transmitting coil and the first transmitting coil are decoupled from each other, which is not repeated herein.
The fourth transmitting coil applies an alternating current I similar to the effect of the fourth coil on the first coil P4 In the process, the magnetic field interference suffered by the third transmitting coil is as shown in fig. 13, the magnetic field interference which is generated by the fourth transmitting coil and has the same strength and the opposite direction is suffered within the range of the third transmitting coil, and in a comprehensive view, the magnetic field intensity suffered by the third transmitting coil is 0, that is, the two coils are decoupled with each other. Similarly, the interference of the fourth transmitting coil to the third receiving coil is also 0.
In conclusion, the fourth transmitting coil has no interference to the third coils (the transmitting coil and the receiving coil).
In summary, it can be known from the analysis that, in the 4-channel simultaneous transmission composite coupling mechanism provided herein, when any one pair of coils of the four pairs of coils works, the other three pairs of coils are not affected; the device can have the function of simultaneously transmitting energy and signals; the energy or signal transmission redundancy design is provided, namely when one path of energy or signal transmission channel fails, the other path of energy or signal transmission channel can work normally and is not affected; the 4-way channels can work simultaneously.
