Bar 50 is formed as cylindric.Bar 50 and the top of the both ends 30B of piston 30 are continuous, and along two sides of piston 30 To extension.Bar 50 extends on the central axis direction of cylinder 10, and from the respective open end 10A at the both ends of cylinder 10 to cylinder The external of body 10 protrudes.That is, piston 30 and bar 50 link.Bar guide portion 70 is formed as having flange part 70B in periphery It is discoid, and by by the respective open end 10A at the both ends of cylinder 10 it is closed in a manner of and with each open end 10A Connection.Above-mentioned bar guide portion 70 is provided with through hole 70A in a manner of perforative on plate thickness direction at discoid center. The internal diameter of through hole 70A is more slightly larger than the outer diameter of bar 50.Through hole 70A is fixed in each of the both ends of cylinder 10 in bar guide portion 70 From open end 10A in the state of, run through on the central axis direction of cylinder 10.Bar 50 is in a manner of back and forth moving freely And it is inserted through in the through hole 70A of above-mentioned bar guide portion 70.Bar 50 and piston 30 are together in cylinder 10 along cylinder 10 Mandrel direction moves back and forth freely.In addition, cylinder 10, piston 30, bar 50 and a pair of of bar guide portion 70 are nonmagnetic material.

As shown in Fig. 2, multiple magnetic-particles 90 are formed as spherical form.These magnetic-particles 90 are A type Shore durometer Measure the elastomer for the silicon rubber as elastomer that hardness (hereinafter referred to as hardness) is 60.In addition, these magnetic-particles 90 In contain neodymium (Nd) particle 90A.The amount of neodymium (Nd) the particle 90A contained in these magnetic-particles 90 is about 60wt.% (17.78vol.%).Neodymium (Nd) particle 90A has magnetism.That is, magnetic-particle 90 has magnetic and elasticity.With this These magnetic-particles 90 that kind mode is formed are magnetized have magnetic force.That is, these magnetic-particles 90 have permanent magnet Characteristic.These magnetic-particles 90 are filled in the sky surrounded by cylinder 10 and a pair of of bar guide portion 70 with 60% filling rate Interior (that is, in cylinder 10).

Here, filling rate is indicated by following mathematical expressions (1).In addition, packing volume refers to filled with magnetic-particle 90 Space volume.

Mathematical expression (1)

Coil part 20 is the component being formed as follows, that is, is coaxially twined on surface by the metal wire that insulating film covers Around multi-turn, there is scheduled width radially, and be bundled into the internal diameter cylindrical shape more slightly larger than the outer diameter of cylinder 10.In addition, The metal wire of coil part 20 becomes such as flowering structure, that is, both ends are brought out respectively, and will be based on the sense generated in coil part 20 The electric current answering electromotive force and generating supplies (not shown) to electrical equipment that the outside with generating function damper 1 is arranged in etc.. Coil part 20 is with the cylindric inside insertion cylinder 10 in coil part 20 and makes the cylindric inside of coil part 20 along cylinder The mode of the outer peripheral surface of body 10 and be configured on the outer peripheral surface of cylinder 10.

In the band generating function damper 1 being formed in this way, when piston 30 is in the central axis direction of cylinder 10 When upper reciprocating movement, scheduled gap of the magnetic-particle 90 across the outer peripheral surface of piston 30 and the inner peripheral surface of cylinder 10 and into Row movement.At this point, between the inner peripheral surface and the magnetic-particle 90 that is abutted with the inner peripheral surface of cylinder 10 of cylinder 10, adjacent magnetism Between particle 90 and the outer peripheral surface of bar 50 and piston 30 and the magnetic-particle abutted with the outer peripheral surface of bar 50 and piston 30 Frictional force can be generated between 90.In addition, being located at the magnetic-particle 90 of the mobile side of piston 30 by 30 be collapsed of piston.At this point, logical Cross the elastic recoil power caused by the magnetic-particle 90 of 30 be collapsed of piston, and by piston 30 toward pushing back.That is, with power generation Function damper 1 generates damping force based on the frictional force and elastic recoil power generated in this way.

In addition, as shown in Figure 11 (A), when being located at the magnetic-particle 90 of the mobile side of piston 30 by 30 be collapsed of piston, Pressing force F can be applied to magnetic-particle 90.The inclined surface of pressing force F being oriented relative to both ends 30B and vertical direction. Pressing force F can be divided into the component on the direction of the component F1 on the central axis direction of cylinder 10 and the central axis far from cylinder 10 F2.It is mobile to the direction of the central axis far from cylinder 10 by component F2 by the magnetic-particle 90 of 30 be collapsed of piston.

In contrast, in the case where not having piston the band generating function damper 61 as shown in Figure 11 (B), when Bar 550 when being moved on the central axis direction of cylinder 10, the magnetic-particle 90 that is abutted with the outer peripheral surface of bar 550 can by its with The frictional force that is generated between the outer peripheral surface of bar 550 and rotate or moved together with bar 550.That is, living not having In the case where plug, magnetic-particle 90 will not be carried out mobile 550 be collapsed of bar on the central axis direction of cylinder 10.Therefore, no The case where applying pressing force there are magnetropism particle 90, thus compared with the case where being provided with piston, the flowing of magnetic-particle 90 It is smaller.

That is, the magnetic-particle 90 being filled in cylinder 10 can be made more actively to carry out by setting piston 30 Flowing.

In addition, at this point, multiple magnetic-particles 90 are formed by the direction of the magnetic line of force along with the past of bar 50 and piston 30 Multiple movement and change, become so that multiple magnetic-particles 90 are formed by the magnetic line of force perforative quantity in coil part 20 Change, therefore generates induced electromotive force in coil part 20.That is, being carried out with generating function damper 1 by coil part 20 Power generation.

Next, showing expression in Fig. 3 (A), (B) by bar 50 and piston 30 with generating function damper 1 Frequency be set as the variation of the size of induced electromotive force in the case where 1Hz, generating in coil part 20 relative to the time Curve graph.Specifically, (A) indicates variation of the size of the induced electromotive force of period 1 relative to the time, (B) indicates the tenth Variation of the size of the induced electromotive force in period relative to the time.

As shown in Fig. 3 (A), (B), in bar 50 and piston 30 in the whole areas for carrying out movement on the central axis direction of cylinder 10 In domain, there is induced electromotive force.In addition, the waveform of the induced electromotive force generated within period 1 and the tenth period is each other not Together.This be considered as due to, whenever bar 50 and piston 30 on the central axis direction of cylinder 10 when repeating to move back and forth, multiple magnetic Property particle 90 possessed by the direction of the magnetic line of force can change, therefore the variation side of the quantity of the magnetic line of force in thorough coil portion 20 Formula is different.

Next, showing expression in Fig. 4 (A), (B) by bar 50 and piston 30 with generating function damper 1 Frequency be set as the variation of the size of induced electromotive force in the case where 5Hz, generating in coil part 20 relative to the time Curve graph.Specifically, (A) indicates variation of the size of the induced electromotive force of period 1 relative to the time, (B) indicates the tenth Variation of the size of the induced electromotive force in period relative to the time.

As shown in Fig. 4 (A), (B), in bar 50 and piston 30 in the whole for carrying out movement on the central axis direction of cylinder 10 In region, there is induced electromotive force.In addition, compared with the case where frequency of bar 50 and piston 30 is 1Hz, induced electromotive force Size it is larger.This is considered as due to being filled in magnetic-particle 90 in cylinder 10 more compared with the case where frequency is 1Hz It is actively flowed, so that the quantity of the perforative magnetic line of force in coil part 20 be made more actively to change.In addition, at first week The waveform of the induced electromotive force generated in phase and the tenth period is different from each other.This is considered as due to whenever bar 50 and piston 30 on the central axis direction of cylinder 10 when repeating to move back and forth, and the direction of the magnetic line of force possessed by multiple magnetic-particles 90 can be sent out Changing, therefore the variation pattern of the quantity of the magnetic line of force in thorough coil portion 20 is different.

Next, shown in Fig. 5 (A), (B) make the bar 50 with generating function damper 1 and piston 30 frequency 1~ Between 5Hz every time in each situation with 1Hz and when being changed, the induced electromotive force that is generated in coil part 20 and be based on Induced electromotive force and the size of electric power generated.Specifically, Fig. 5 (A) indicate make bar 50 and piston 30 with scheduled time The size of the average value for the induced electromotive force that number generates in coil part 20 in a period of being moved back and forth, Fig. 5 (B) are indicated The size of the electric power generated based on the induced electromotive force generated in coil part 20.Specifically, for each in Fig. 5 (A) Value obtained from the average value of induced electromotive force under frequency is squared is divided by resistance value possessed by coil part 20 (about 6.5 Ω (ohm)) obtained value.

As shown in Fig. 5 (A), (B), the frequency with bar 50 and piston 30 becomes larger, the induction generated in coil part 20 The size of electromotive force and the electric power generated based on the induced electromotive force generated in coil part 20 is become larger.This be considered as by In, the frequency with bar 50 and piston 30 becomes larger, and the magnetic-particle 90 being filled in cylinder 10 can more actively be flowed, To which the quantity of the perforative magnetic line of force more actively changes in coil part 20.

In this way, in band generating function damper 1, when bar 50 and piston 30 are reciprocal on the central axis direction of cylinder 10 When mobile, carried out in cylinder 10 by the magnetic-particle 90 being filled in cylinder 10 mobile to generate damping force.

In addition, when the direction that the multiple magnetic-particles 90 for carrying out movement in cylinder 10 are formed by the magnetic line of force changes When, the quantity of the perforative magnetic line of force can change in coil part 20.Thus induced electromotive force is generated in coil part 20.? That is band generating function damper 1 generates electricity.

Therefore, band generating function damper 1 of the invention can generate damping force well, and can carry out well Power generation.

In addition, the magnetic-particle 90 with generating function damper 1 has elasticity.Therefore, when bar 50 is reciprocal in axial direction When moving or being rotated around axis, flexible deformation can occur for the multiple magnetic-particles 90 being filled in cylinder 10.By at this time The mutual frictional force of magnetic-particle 90 of generation and the elastic recoil power of magnetic-particle 90, to make band generating function damper 1 Generate damping force.Further, since magnetic-particle 90 has elasticity, therefore elasticity can mutually occur each other for adjacent magnetic-particle 90 Deformation, thus make magnetic-particle 90 be not easy each other it is hot sticky together.Therefore, band generating function damper 1 is not easy that bar 50 is interfered to exist Reciprocating movement in axis direction or the rotation around axis.

In addition, having piston 30 with generating function damper 1, which is configured in cylinder 10, and is connected with bar 50 Knot, and moved back and forth together with bar 50.Therefore, band generating function damper 1 can make to be filled in by piston 30 Magnetic-particle 90 in cylinder 10 is more actively flowed.Therefore, in band generating function damper 1,90 institute of magnetic-particle The magnetic line of force having can be passed through more actively in coil part 20.As a result, in band generating function damper 1, in coil part 20 The quantity of the interior perforative magnetic line of force is easy to more actively change, to be easy to generate bigger induced electricity in coil part 20 Kinetic potential.
