According to embodiments of the invention, provide a kind of magnet spring.Described magnet spring comprises: supporting frame 40, is at least arranged at the elastic oscillation unit (such as: elastic oscillation unit 50) at one of support frame as described above 40 two ends, and is installed on the driver element between support frame as described above two ends; Described elastic oscillation unit, comprising: the linear oscillating magnetite being installed on support frame as described above end, and isolation is arranged at the upper and lower fixing magnetite group of linear oscillating magnetite respectively, makes support frame as described above end be suspended in the middle of described fixing magnetite group; Described driver element is driven, by being at least arranged at the synergy (namely by being arranged at support frame as described above two ends or being arranged at the synergy of elastic oscillation unit at one of support frame as described above two ends) of the elastic oscillation unit at one of support frame as described above two ends, support frame as described above is made to carry out straight reciprocating motion.By the driving of driver element and the synergy of elastic oscillation unit, make supporting frame carry out straight reciprocating motion, can realize straight line elastic compression or stretching, extension, energy storage capacity is strong, and assembling difficulty is little; The alternative resonant springs of this magnet spring, high to improve reliability, and increase the service life.
Particularly, described driver element, comprises the driving magnetite 42 be installed between support frame as described above two ends.Drive magnetite as driver element by adopting, can better with the acting in conjunction of elastic oscillation unit, be conducive to improving the straight line elastic movement ability of supporting frame.
In one example in which, contrary by the magnetizing direction of driver element being set to magnetizing direction that is consistent with the magnetizing direction organizing fixing magnetite and the straight-line oscillation magnetite at supporting frame two ends more, the straight reciprocating motion of straight-line oscillation magnetite can be realized better, and the good stability of motion.
Preferably, described fixing magnetite group comprises the first fixing magnetite group, described first fixing magnetite group comprises four fixing magnetites (such as: the fixing magnetite 52 of the first fixing magnetite 51, second, the 3rd fixing magnetite 53 and the 4th fixing magnetite 54), and described four fixing magnetites cover in described linear oscillating magnetite peripheral in the Vertical direction of linear oscillating magnetite in matrix pattern symmetry.By the staggered formation elastic oscillation unit of fixing magnetite and linear oscillating magnetite, the stability of magnetic intensity and reliability all can be protected.
Such as: see Fig. 4, as the major scheme one of the present invention program, on mover, monolateral magnet spring adopts 6 magnetites (such as: the first linear oscillating magnetite 61 and the second linear oscillating magnetite 62, and first fixes magnetite 51, second fixing magnetite 52, 3rd fixing magnetite 53 and the 4th fixing magnetite 54), wherein two panels magnetite (such as: the first linear oscillating magnetite 61 and the second linear oscillating magnetite 62) is fixed on mover supporting frame, 4 magnetites (such as: the first fixing magnetite 51, second fixing magnetite 52, 3rd fixing magnetite 53 and the 4th fixing magnetite 54) be fixed on corresponding fixed block (such as: compressor frame or frame extend estimates part), the magnetizing direction (such as: polarity) of magnetite as shown in Figure 4, adopt the principle design of two like magnetic poles repel each other, effectively can be suspended subpart.Wherein, drive part (such as: driver element), for simplifying replacing representation, can adopt kinds of schemes.
In one embodiment, the described first fixing magnetite group is arranged around one end of described linear oscillating magnetite.
Wherein, described fixing magnetite group also comprises the second fixing magnetite group, and the described second fixing magnetite group is identical with the described first fixing magnetite group structure, and the other end around described linear oscillating magnetite is arranged.
Thus, a linear oscillating magnetite and corresponding fixing magnetite group can be adopted to be equipped with, to realize the straight reciprocating motion of supporting frame.Such as: see Fig. 6, aforementioned body scheme one can be adjusted to, and saves a slice magnetite on mover supporting frame, and magnet spring also can work (protection derivative schemes); The magnet spring of the present embodiment adopts the motion of pole polarity tangential direction and force design, as shown in Figure 7 stressed.Because the energy density of magnetite is comparatively large, compares steel spring, volume can be accomplished less, so by the staggered formation elastic oscillation unit of magnetite, magnetic intensity is stablized.On the contrary, adopt the magnet spring as Fig. 9 conceptual design, cannot ensure that mover is stable on side direction, there will be lateral deviation, the wearing and tearing that compressor pump is larger can be caused.
In one embodiment, described linear oscillating magnetite comprises at least two, and at least two linear oscillating magnetites are arranged along the straight reciprocating motion direction of support frame as described above; Magnetite group is fixed around being provided with described in one group between every two linear oscillating magnetites.Can magnetic intensity be strengthened by least two linear oscillating magnetites, and then strengthen the reliability and stability of fixing magnetite motion.
Wherein, the spacing between every two linear oscillating magnetites, is greater than the monolateral amplitude of linear oscillating.
Such as: magnetite can use strong magnetic material, adopt the mode that polylith magnetite is staggered, as Fig. 4, the upper two panels magnetite (such as: the first linear oscillating magnetite 61 and the second linear oscillating magnetite 62) of supporting frame 40 (such as: mover supporting frame), identical and the magnetizing direction of the polarity of this two panels magnetite all upwards, magnetite spacing is greater than the monolateral amplitude of linear oscillating, and this monolateral amplitude is the ultimate range that the first elastic oscillation unit or the second elastic oscillation unit leave equilibrium position.All the other 4 magnetites (such as: the fixing magnetite 52 of the first fixing magnetite 51, second, the 3rd fixing magnetite 53 and the 4th fixing magnetite 54) cover the two panels magnetite of supporting frame 40 end winding support in covering form, all the other 4 magnetites are matrix pattern.
In one embodiment, described linear oscillating magnetite comprises at least two (such as: the first linear oscillating magnetite 61, second linear oscillating magnetite 62, the 3rd linear oscillating magnetite 63 and the 4th linear oscillating magnetite 64), and at least two linear oscillating magnetites are arranged along the straight reciprocating motion direction of support frame as described above; In identical one end of each linear oscillating magnetite around being provided with described fixing magnetite group, form cascaded structure (such as: the connect with first to fourth fixing magnetite the five to six fixing magnetite, as the 5th fixing magnetite 55, the 6th fixing magnetite 56, the 7th fixing magnetite 57 and the 8th fixing magnetite 58).Fix magnetite by expanding contrary at least one group of the magnetizing direction of fixing magnetite with original one group, can control straight reciprocating motion better, control accuracy is high, good stability.
Such as: see Figure 12, can continue to increase series connection at mover supporting frame end, thus promote the capacity of magnet spring.Figure 12 only represents monolateral increase, and be suitable for single cylinder compression occasion, the left side is exhaust end.
Wherein, by being set to by the magnetizing direction of fixing magnetite multiple in an elastic oscillation unit consistent and the magnetizing direction of two straight-line oscillation magnetites is set on the contrary, energy storage capacity and the stability of magnet spring can be improved.
In one embodiment, described linear oscillating magnetite comprises at least two row, and described linear oscillating magnetite of often going comprises a linear oscillating magnetite; At least two row linear oscillating magnetites are parallel along the straight reciprocating motion direction of support frame as described above to be arranged, and in identical one end of every row linear oscillating magnetite around being provided with described fixing magnetite group, and the fixing magnetite between two row shares, and forms parallel-connection structure.Such as: see Figure 14, mode in parallel can be adopted to increase the capacity of magnet spring.By expanding fixing magnetite and adjusting the arrangement mode of straight-line oscillation magnetite, the stored energy capacitance of magnet spring can be expanded better, and improve stable magnetic field.
In one embodiment, described linear oscillating magnetite comprises at least two row, and at least two row linear oscillating magnetites are along the parallel setting in straight reciprocating motion direction of support frame as described above; Described linear oscillating magnetite of often going comprises at least two linear oscillating magnetites, and at least two linear oscillating magnetites are arranged along the straight reciprocating motion direction of support frame as described above; Between two linear oscillating magnetites, fix magnetite group around being provided with described in one group, and the fixing magnetite between two row shares.
Thus, magnet spring capacity can adopt the form of parallel connection or series connection, increases the stored energy capacitance of magnet spring.As increased by 4 matrix pattern magnetites in Fig. 4 at mover supporting frame tail end, to increase on mover supporting frame linear oscillating magnetite 3 or more.Also can walk abreast increase by 2 magnetites on mover supporting frame, makes matrix pattern magnetite increase to 6 or more, and the energy storage realizing magnet spring increases.Increased the quantity of magnetite by adaptability, the capacity of magnet spring can be expanded, strengthen magnetic intensity, and then be more conducive to the stability and the reliability that improve straight reciprocating motion.

Such as: see Figure 13, change the scheme of magnetizing direction as above-mentioned derivative schemes one, in Figure 12, monolateral magnet spring goes out force direction both direction, is more similar to the compression stretching state of steel spring.In Figure 12, mover (such as: driver element) current position is dead-center position, to left movement, to the right stressed, moves right, left stressed.And the magnet spring in Figure 13, being equivalent to steel spring has carried out precompressed, equilibrium position shown in Figure 12, and mover left-hand component is always by active force to the right.In Figure 12, Figure 13, both sides spring is not of uniform size causes, and initial balance is not at shown position, and this form, is conducive to design particular service requirement and uses.
Thus, consistent and contrary with the magnetizing direction of a straight-line oscillation magnetite by the magnetizing direction of each fixing magnetite is set to, stability and the reliability of straight reciprocating motion can be improved.
Such as: see Fig. 5, as the two-dimensional effects figure of aforementioned body scheme one, the polar orientation of the program No. 3 magnetites (S3 see Fig. 4) can be exchanged, and obviously can promote the energy storage effect of magnet spring.
Thus, by exchanging the polar orientation of linear oscillating magnetite, the energy storage capacity of magnet spring can be promoted as required, and reduce assembling difficulty.Such as: see Fig. 7, monolateral magnet spring adopts 9 magnetite designs, and the upper employing of mover supporting frame (such as: supporting frame 40) 1 magnetite design, magnetite magnetizing direction such as Fig. 5 describes adjustable.Because the polar orientation of this magnetite can be exchanged, the energy storage effect of magnet spring obviously can be promoted.

Such as: see Figure 10, adopt the analysis of Fig. 6 model emulation to exert oneself, exert oneself with distance change as left figure.Middle magnetite position from Figure 11 is downward with the speed of 1mm/s.After being greater than 6mm, the linearity is better applicable to using very much.
In fig. 11, wherein, F1 represents the repulsive force of lower-left magnetite to it, and F2 represents the repulsive force of bottom right magnetite to it, and upwards, the power of left and right directions is balance to the resultant direction of F1, F2; N, S represent pole orientation and the polarity of magnetite, and 1mm/s to represent in emulation that model is adopted and carries out dynamic simulation in this way, just in time obtain time shaft numeral with apart from digital one_to_one corresponding.
