Mutually combination.The disclosure is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Fig. 1,2,4, the magnetic force of the disclosure vibrates linear generating set, comprising: cylinder body 1, piston 2, iron core 3, forever
Magnet 4, winding coil 5 and elastomeric element 6；Piston 2, iron core 3, permanent magnet 4 and elastomeric element 6 are arranged at the inner cavity of cylinder body 1
In；Iron core 3 is fixedly connected with piston 2, and winding coil 5 is wrapped on iron core 3, and piston 2 can carry out reciprocal along the inner wall of cylinder body 1
Movement；Permanent magnet 4 is fixed in the cavity of cylinder body 1, and elastomeric element 6 is fixed in the cavity of cylinder body 1, and permanent magnet 4 and elasticity
Component 6 is located at the two sides of piston 2.
The magnetic force vibration linear generating set of the disclosure further includes air collecting chamber 9, and air collecting chamber 9 is connected to the inner cavity of cylinder body 1.Cylinder
Exhaust outlet 11 is provided on the side wall of body 1.Elastomeric element 6 is fixed on one end of cylinder body 1 by elastomeric element seat 7, and permanent magnet 4 is logical
Permanent magnet supporting plate 8 is crossed to be fixed in the cavity of cylinder body 1.Air collecting chamber 9 is connected to by pressure maintaining valve 10 with the inner cavity of cylinder body 1.
The interior sidewall surface of cylinder body 1 is provided with left stop 12 and right stop 13, and left stop 12 and right stop 13 are for limiting work
The displacement that plug 2 moves back and forth in the cavity of cylinder body 1.When power generator works, piston 2 is between left stop 12 and right stop 13
It moves back and forth, gas in the jar can pass through the periodically discharge cylinder body of exhaust outlet 11.
It is provided with through-hole on permanent magnet supporting plate 8, for passing through for air-flow.It is fixed with one end of the cylinder body 1 of elastomeric element seat 7

Iron core 3 has cavity, and permanent magnet 4 also has cavity, and the cavity of the cavity and permanent magnet 4 of iron core 3 is oppositely arranged.
In more detail, as shown in Fig. 2, not having when speed (or speed of ship, track train, aircraft etc.) is not high enough
When reaching setting value, gas pressure is smaller in air collecting chamber 9, can not open pressure maintaining valve 10, flows into cylinder body 1 without gas, this
When, piston 2 left and right sides gas pressure, the suction of permanent magnet 4, the repulsion of elastomeric element 6, left stop 12 support force work
It is balanced with lower holding, is still in the position of left stop 12.
As shown in Figure 2,3, the active force that piston 2 is subject to has the intracorporal gas pressure F1 (to the right) of 2 left side cavity of piston, permanent magnetism
