Oscillating linear motor with rotors, stator and swing rod fixed to seat
View Patent ↗The present disclosure discloses an oscillating linear motor, including a housing. A coil fixing base for winding a coil is mounted in the housing. A stator is fixed to an interior of the coil fixing base. Rotors float at a top of the stator. Two groups of rotors are arranged symmetrically. A movable bottom seat is arranged above each group of rotors. The movable bottom seats are driven to move by respective rotors. Both sides of the movable bottom seat are connected to connecting pieces. An upper end and a lower end of the connecting piece are respectively connected to the housing and the movable bottom seat. A swing rod is fixed to an upper part of each movable bottom seat.
1 . An oscillating linear motor with rotors, stator and swing rod fixed to seat, comprising a housing ( 1 ), wherein a coil fixing base ( 21 ) for winding a coil is mounted in the housing ( 1 ); a stator is fixed to an interior of the coil fixing base ( 21 ); rotors ( 23 ) float at a top of the stator; two groups of rotors ( 23 ) are arranged symmetrically; two movable bottom seats ( 8 ) are respectively arranged above two groups of rotors ( 23 ); each of the two movable bottom seats ( 8 ) is driven to move by respective group of rotors ( 23 ); both sides of the movable bottom seat ( 8 ) are connected to connecting pieces ( 3 ); an upper end and a lower end of the connecting piece ( 3 ) are respectively connected to the housing ( 1 ) and the movable bottom seat ( 8 ); and each of two swing rods ( 4 ) is fixed accordingly to each of the two movable bottom seats ( 8 );
wherein the housing ( 1 ) is provided with a lower chamber for placing the coil fixing base ( 21 ) and an upper chamber for accommodating the swing rods ( 4 ); an upper top plate ( 13 ) is fixed to a top of the upper chamber; and an upper end of the connecting piece ( 3 ) is fixed to the upper top plate ( 13 );
wherein a linkage piece ( 6 ) is in butt-joint between the two swing rods ( 4 ); and the linkage piece ( 6 ) enables one of the swing rods ( 4 ) to drive the other swing rod ( 4 ) to move in another direction when moving; a fixed shaft ( 7 ) is arranged in a center of the linkage piece ( 6 ); the fixed shaft ( 7 ) is rotatably connected to the upper top plate ( 13 ); the linkage piece ( 6 ) is provided with a linkage groove ( 61 ) by taking the fixed shaft ( 7 ) as a center of symmetry; and linkage columns ( 41 ) that match the linkage grooves ( 61 ) are respectively arranged on the swing rods ( 4 ).
2 . The oscillating linear motor with rotors, stator and swing rod fixed to seat according to claim 1 , wherein a magnetic block ( 24 ) is fixed to a lower part of the movable bottom seat ( 8 ); and the stator is fixed to the magnetic block ( 24 ) in an embedded manner.
3 . The oscillating linear motor with rotors, stator and swing rod fixed to seat according to claim 1 , wherein one of the swing rods ( 4 ) is mounted with a drive rod ( 5 ) after upwards extending out of the housing ( 1 ).
4 . The oscillating linear motor with rotors, stator and swing rod fixed to seat according to claim 1 , wherein a reset spring ( 2 ) is arranged between each of two sides of each swing rod ( 4 ) and a wall surface of the upper chamber.
5 . The oscillating linear motor with rotors, stator and swing rod fixed to seat according to claim 1 , wherein the swing rods ( 4 ) are in an inverted T-shape and are provided with triangular reinforcement plates.
