Embodiment Construction

[0025] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0026] Such as Figure 1-5 As shown, a miniature reciprocating swing motor structure includes a casing 3, a rotor and a stator, and the stator includes a cylindrical permanent magnet 4 fixedly installed in the casing 3, and the left semicircle of the permanent magnet 4 is the South Pole, and the right semicircle is the North Pole;

[0027] The rotor includes a rotating shaft 8 inserted in the permanent magnet 4, the rotating shaft 8 is provided with a rotor core 7, and the rotor core includes an iron core block 7a hooped on the rotating shaft 8, so The two sides of the iron core block 7a are respectively connected with arc-shaped plates 7b, the iron core block 7a and the two arc-shaped plates 7b are integrally formed, and together they form the rotor iron core 7 in the shape of an "I". The middle part of each arc-shaped plate 7b is respectively facing...

Abstract

The invention discloses a miniature reciprocating swinging motor structure, and the structure comprises a motor case, a rotor, and a stator. The stator comprises a permanent magnet fixedly installed in the motor case, and the left and right half circles of the permanent magnet respectively serve as a south pole and a north pole. The rotor comprises a rotating shaft inserted into the permanent magnet, and the rotating shaft is provided with a rotor core. The rotor core comprises an iron core block hooping the rotating shaft, and the two side edges of the iron core block are respectively connected with arc-shaped plates, wherein the central parts of the two arc-shaped plates face the boundary line of the south pole and north pole of the permanent magnet. The iron core is provided with coil windings, corresponding to the two arc-shaped plates, in a winding manner. The directions of magnetic fields generated by the two coil windings are the same. The stator magnet is of a complete cylindrical structure, and the swinging amplitude of the motor is larger. The structure is better in reliability. Moreover, the structure saves a spring in a conventional swinging motor, and greatly prolongsthe service life of a product. The winging device can be widely used on a face massager and a health care product.

Description

technical field [0001] The invention relates to the technical field of micro motors, in particular to a micro motor structure with reciprocating swings. Background technique [0002] The domestic market of electric toothbrushes has gradually increased in recent years, and more and more people use them. It is precisely because of the increasing number of users that there are more and more personalized requirements for electric toothbrushes. Swing frequency, swing amplitude, etc. are the main performance indicators, which are valued by different users. At present, the traditional motors that realize reciprocating swing mainly use the following methods to realize the reciprocating swing of the output: (1) install an eccentric block on the output shaft of the DC iron core motor, and the rotation of the motor drives the rotation of the eccentric block, thereby generating vibration; 2) Use the crank swing mechanism or the cam swing mechanism to convert the continuous rotation mot...
