[0034] Specifically, the resonant reciprocating power assembly described in this embodiment is formed by integrally injecting the base 1, the bracket and the spring sheet mechanism, which can optimize the installation method of the product, reduce the use of screws and the uncertainty caused by screw installation, and improve the consistency and qualification rate of the product.

[0035] In the resonant reciprocating translational power assembly described in this embodiment, the stator mechanism comprises a first core column group and a second core column group which are arranged at intervals;

[0036] The first core column group includes a first left core column 31, a first right core column 32 and a first middle core column 33 arranged in sequence;

[0037] The second core column group includes a second left core column 41, a second right core column 42 and a second middle core column 43 which are arranged in sequence;

[0038] A coil 5 is wound between the first central core column 33 and the second central core column 43; the bracket includes a first bracket 6 and a second bracket 7; the first bracket 6 is reciprocatingly movable and arranged at the top of the first core column group; the second bracket 7 is reciprocatingly movable and arranged at the top of the second core column group;

[0039] The mover mechanism includes a first mover core 62 provided on the first bracket 6 and a second mover core 72 provided on the second bracket 7;

[0040] The magnet mechanism includes a first magnet assembly disposed on the first movable core 62 and a second magnet assembly disposed on the second movable core 72 .

[0041] Specifically, in the resonant reciprocating power assembly described in this embodiment, a first stator system is formed between the first left core column 31, the first right core column 32, the first middle core column 33 and the coil 5, and a second stator system is formed between the second left core column 41, the second right core column 42, the second middle core column 43 and the coil 5; in addition, a first mover system is formed between the first bracket 6, the first mover core 62 and the first magnet assembly, and a second mover system is formed between the second bracket 7, the second mover core 72 and the second magnet assembly.

[0042] When powered on, the first stator system and the second stator system apply horizontal excitation forces of varying sizes to the first mover system and the second mover system respectively, cooperating with the electromagnetic excitation force perpendicular to the surface of the first magnet assembly and the electromagnetic excitation force perpendicular to the surface of the second magnet assembly, thereby causing system resonance, thereby enabling the first bracket 6 and the second bracket 7 to perform reciprocating translational activities.

[0043] In this embodiment, the first core column group and the second core column group are integrated in the stator mechanism 2, and the coil 5 only needs to be wound between the first middle core column 33 and the second middle core column 43, thereby reducing the number of windings of the coil 5, reducing the production process, and effectively improving costs.

[0044] In the resonant reciprocating power assembly of the present embodiment, the first magnet assembly includes a first left magnet 63 and a first right magnet 64 disposed at the bottom of the first mover core 62; the first left magnet 63 is disposed at the top of the first left core column 31 and the top of the first middle core column 33; the first right magnet 64 is disposed at the top of the first right core column 32 and the top of the first middle core column 33;

[0045] The second magnet assembly includes a second left magnet 73 and a second right magnet 74 arranged at the bottom of the second movable core 72; the second left magnet 73 is arranged at the top of the second left core column 41 and the top of the second middle core column 43; the second right magnet 74 is arranged at the top of the second right core column 42 and the top of the second middle core column 43.

[0046] Specifically, after the coil 5 is energized, magnetic poles can be generated at the top of each iron core, so that the first bracket 6 can be driven to move laterally under the action of the first left magnet 63 and the first right magnet 64, and the second bracket 7 can be driven to move laterally under the action of the second left magnet 73 and the second right magnet 74;

[0047] When a reverse current flows through the coil 5, the magnetic poles at the top of each iron core change, thereby driving the first bracket 6 to move in the opposite direction under the action of the first left magnet 63 and the first right magnet 64, and driving the second bracket 7 to move in the opposite direction under the action of the second left magnet 73 and the second right magnet 74; by continuously changing the current direction of the coil 5, the first bracket 6 and the second bracket 7 can be made to perform reciprocating translational movements.

[0048] In the resonant reciprocating power assembly described in this embodiment, the first left magnet 63 and the first right magnet 64 are arranged in parallel at the bottom of the first mover core 62; the second left magnet 73 and the second right magnet 74 are arranged in parallel at the bottom of the second mover core 72. Through the above arrangement, the stability of the movement of the first bracket 6 and the stability of the movement of the second bracket 7 can be enhanced.

[0049] In the resonant reciprocating power assembly described in this embodiment, the first left core column 31 is arranged opposite to the second left core column 41; the first right core column 32 is arranged opposite to the second right core column 42; the first middle core column 33 is arranged opposite to the second middle core column 43;

[0050] There are gaps 21 between the first left core column 31 and the second left core column 41, between the first right core column 32 and the second right core column 42, and between the first middle core column 33 and the second middle core column 43. Specifically, through the above arrangement, the overall structure of the resonant reciprocating power assembly is more stable and reliable.

[0051] In the resonant reciprocating power assembly described in this embodiment, an insulating frame 51 is sleeved between the first central column 33 and the second central column 43; the coil 5 is wound on the insulating frame 51; specifically, through the above-mentioned insulation effect, and the insulating frame 51 is sleeved outside the first central column 33 and the second central column 43 at the same time, the stability of the overall structure can be enhanced. A first output shaft 61 is provided at the top of the first bracket 6; a second output shaft 71 is provided at the top of the second bracket 7. Specifically, the above-mentioned arrangement enables the overall output to be dual-axis.

[0052] In the resonant reciprocating power assembly described in this embodiment, a first left spring sheet 81 is provided between the first bracket 6 and the base 1 on one side of the moving direction; a first right spring sheet 82 is provided between the first bracket 6 and the base 1 on the other side of the moving direction;

[0053] A second left spring piece 91 is provided between the second bracket 7 and the base 1 on one side of the moving direction; a second right spring piece 92 is provided between the second bracket 7 and the base 1 on the other side of the moving direction;

[0054] The first left spring leaf 81 , the first right spring leaf 82 , the second left spring leaf 91 , and the second right spring leaf 92 constitute the spring leaf mechanism.

[0055] Specifically, in this embodiment, by providing a first left spring piece 81, a first right spring piece 82, a second left spring piece 91 and a second right spring piece 92, each spring piece can be deformed during the reciprocating motion of the first bracket 6 and the second bracket 7, thereby further ensuring the resonance of the first bracket 6 and the second bracket 7.

[0056] In the resonant reciprocating power assembly described in this embodiment, the first left spring piece 81, the first right spring piece 82, the second left spring piece 91 and the second right spring piece 92 are single-piece structures or are formed by stacking multiple spring pieces; the first left spring piece 81, the first right spring piece 82, the second left spring piece 91 and the second right spring piece 92 are all provided with through holes. The provision of the through holes can reduce stress concentration and increase the life of the spring pieces.

[0057] In the resonant reciprocating power assembly described in this embodiment, the magnetism at the bottom of the first left magnet 63 is opposite to the magnetism at the bottom of the first right magnet 64; the magnetism at the bottom of the second left magnet 73 is opposite to the magnetism at the bottom of the second right magnet 74;

[0058] The magnetism at the bottom of the first left magnet 63 is the same as the magnetism at the bottom of the second left magnet 73; the magnetism at the bottom of the first right magnet 64 is the same as the magnetism at the bottom of the second right magnet 74; specifically, since the coil 5 applies horizontal excitation forces of equal magnitude and opposite directions to the first bracket 6 and the second bracket 7 respectively; the above arrangement enables the first bracket 6 and the second bracket 7 to resonate and reciprocate in opposite directions.

[0059] The magnetism at the bottom of the first left magnet 63 is opposite to the magnetism at the bottom of the first right magnet 64; the magnetism at the bottom of the second left magnet 73 is opposite to the magnetism at the bottom of the second right magnet 74;

[0060] The magnetism at the bottom of the first left magnet 63 is opposite to the magnetism at the bottom of the second left magnet 73; the magnetism at the bottom of the first right magnet 64 is opposite to the magnetism at the bottom of the second right magnet 74. Specifically, since the coil 5 applies equal and opposite horizontal excitation forces to the first bracket 6 and the second bracket 7, the above arrangement enables the first bracket 6 and the second bracket 7 to resonate and reciprocate in the same direction.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
