Description
Technical Field
The utility model relates to the technical field of vibration motors, in particular to a vibrator of a flat brushless vibration motor.
Background
The brushless DC motor is composed of a motor main body and a driver, and is a typical electromechanical integrated product. Because the brushless DC motor operates in a self-control mode, a starting winding is not additionally arranged on a rotor like a synchronous motor which is started under heavy load under variable frequency speed regulation, and oscillation and step-out can not be generated when the load is suddenly changed. The permanent magnet of the brushless DC motor with small and medium capacity is mostly made of rare earth NdFeB (Nd-Fe-B) materials with high magnetic energy level. Therefore, the volume of the rare earth permanent magnet brushless motor is reduced by one base number compared with that of a three-phase asynchronous motor with the same capacity.
The core parts of the products are an eccentric unit with unbalanced mass, a rotor with a coil and a stator magnetic field, the coil is inserted into a stator magnetic field loop, when current is introduced into the coil, the energized coil is driven by Lorentz force to move together with a rotating shaft fixed by the coil, and the rotating shaft drives the eccentric unit fixed by the rotating shaft to rotate, so that vibration is formed. Such a vibration motor generates a rotational force by applying a voltage to a coil, typically through contact of brushes with a commutator, which is a brushed motor, and causes wear of the brushes and the commutator due to mechanical friction and spark generated by the brushes of gaps between segments of the commutator, typically during rotation of the brushed motor, thereby shortening the service life of the vibration motor, and causing a certain damage if the vibrator is in direct contact with a transducer of the motor.

In addition, it is preferable that the vibrator has the same height as the groove height of the spiral groove, and the brushless vibration motor commutates when the vibrator rotates to the limit position while rotating in the spiral groove.
The beneficial effects of the utility model are as follows: the vibrator inside the traditional brushless vibration motor is generally contacted with the output shaft, so that the output efficiency of the output shaft is changed along with the vibration of the vibrator, but if the vibrator is indirectly contacted with the output shaft through the lantern ring, the output efficiency of the output shaft is not affected when the vibrator vibrates, and the output efficiency of the output shaft of the brushless vibration motor is more stable.

Referring to fig. 1 to 5, a flat brushless vibration motor vibrator comprises a brushless vibration motor 1, wherein the brushless vibration motor 1 comprises an output shaft 2, the bottom of the output shaft 2 is connected with a transducer 9, the top of the output shaft 2 is provided with a connecting port 8, and the output shaft 2 is sleeved with a lantern ring 6;
The sleeve ring 6 is provided with a sliding groove 7, the sliding groove is connected with a connecting rod 5 in a sliding way, the tail end of the connecting rod 5 is connected with a vibrator 4, the vibrator 4 is arc-shaped, and the vibrator 4 is in full contact with the connecting rod 5.
Wherein, brushless vibrating motor 1 includes motor housing 11, and motor housing 11 carries out fixed mounting through set screw 3, and motor housing 11 can the inside electronic components of efficient protection brushless vibrating motor 1, prevents ageing.
Meanwhile, the inner wall of the brushless vibration motor 1 is provided with the spiral groove 10, the vibrator 4 slides in the spiral groove 10, and the spiral groove 10 can effectively limit the vibrator 4 to slide in the inner part.
Wherein, vibrator 4 is the pitch arc, and the pitch arc department of vibrator 4 passes through connecting rod 5 and slides in spout 7, so when output shaft 2 rotates, vibrator 4 drives lantern ring 6 and reciprocates at output shaft 2.
Also, the diameter of the output shaft 2 is larger from bottom to top, so the vibration frequency becomes smaller when vibrating to the middle of the output shaft 2.
Also, the vibrator 4 has the same height as the groove height of the spiral groove 10, and the brushless vibration motor 1 commutates when the vibrator 4 rotates to the limit position while rotating in the spiral groove 10.
In the present embodiment, the motor housing 11 is first removed by the fixing screw 3, then the output shaft 2 is taken out, and first, the collar 6 is fitted on the output shaft 2, and the chute 7 is opened in the collar 6.
Firstly, a connecting rod 5 is inserted into a chute 7, then the tail end of the connecting rod 5 is connected with a vibrator 4, the vibrator 4 is pressed into a spiral groove 10 formed in the inner wall of the brushless vibration motor 1, then the brushless vibration motor 1 is electrified, firstly, an output shaft 2 rotates, and the vibrator 4 is driven to spirally rise in the spiral groove 10 by the rotation of the output shaft 2.
Due to the spiral rising of the vibrator 4, the collar 6 also makes a synchronous movement by the connecting rod 5, so that the collar 6 also rises synchronously with the output shaft 2, and since the diameter of the output shaft 2 is from small to large, the brushless vibration motor 1 also works under the influence of the vibrator 4 when the collar 6 moves to the upper side.
In the present utility model, the vibrator 4 inside the conventional brushless vibration motor 1 is generally in contact with the output shaft 2, which causes the output efficiency of the output shaft 2 to change following the vibration of the vibrator 4, but if the vibrator 4 is indirectly in contact with the output shaft 2 through the collar 6, not only the output efficiency of the output shaft 2 is not affected by the vibrator 4 while vibrating, but also the output efficiency of the output shaft 2 of the brushless vibration motor 1 can be made more stable.
