Referring to fig. 1 to 4, according to an aspect of the present application, there is provided a turntable motor assembly 100 including a stopper 4 and two turntable motors 10 horizontally disposed, each turntable motor 10 including a stator 2 and an eccentric mover 1, the stator 2 including a coil assembly, the eccentric mover 1 including a rotation shaft 12 and an eccentric 11, the coil assembly being disposed at a top and/or bottom of the eccentric 11; the eccentric wheels 11 comprise a magnetic assembly 111 rotatably mounted on the rotating shaft 12, and the limiting piece 4 is used for abutting against the two eccentric wheels 11 to limit the rotating angle of each eccentric wheel 11.
The coil assembly of the turntable motor 10 is arranged at the top and/or the bottom of the eccentric wheel 11, the coil assembly is arranged at the top of the eccentric wheel 11, and the coil assembly can be arranged at the bottom of the eccentric wheel 11 or at both the top and the bottom of the eccentric wheel 11. The magnetic assembly 111 of the eccentric wheel 11 is magnetized firstly, specifically, the magnetizing direction can be a direction perpendicular to the paper surface, then the coil assembly is electrified, according to ampere law, the coil 21 on the coil assembly can bear torque, and the coil 21 can simultaneously apply a reaction torque force to the magnetic assembly 111 to drive the eccentric wheel 11 to rotate, the rotation center of the eccentric wheel 11 is the axis of the rotating shaft 12, the mass distribution of the eccentric wheel 11 is not uniform, so that the center of mass of the eccentric wheel 11 is not at the same point as the rotation center of the eccentric wheel 11, and a vibration sense can be generated during rotation. In this embodiment, by providing two turntable motors 10 in horizontal directions, the turntable motor 10 includes an eccentric rotor 1, the eccentric rotor 1 includes an eccentric wheel 11, the center of mass of the eccentric wheel 11 is not located at the center of a rotating shaft 12, and accelerations generated by the two eccentric wheels 11 during rotation and when the two eccentric wheels encounter a limiting member 4 to stop are asymmetrically distributed, which has the effect that asymmetric vibration is generated when the turntable motor assembly 100 works. Further, since the eccentric mover 1 has an eccentric structure, it is self-induced during rotation. Compared with the prior art that an eccentric block is additionally arranged on the rotating shaft 12, the vibration sense can be generated through the improvement of the structure of the eccentric wheel 11, the improvement of the rotating speed of the motor is facilitated, the energy consumption is reduced, and meanwhile, the asymmetric vibration can be generated in the working process through the arrangement of the two horizontally placed turntable motors 10.
In addition, in the present application, the turntable motor 10 is used, and compared with other motors, the turntable motor 10 is not provided with an iron core in structure, so that no cogging torque exists. In particular, cogging torque may cause vibration and noise to the motor, and if the cogging torque is excessive, the motor may stop rotating at a position where the cogging torque is excessive. The existence of cogging torque can also enable the motor to have rotational speed fluctuation, so that the motor can not run stably, and the performance of the motor is affected. In variable speed drive, when the torque ripple frequency coincides with the mechanical resonance frequency of the stator or rotor, vibrations and noise generated by cogging torque will be amplified. The presence of cogging torque also affects the low speed performance of the motor in the speed control system and the high accuracy positioning in the position control system. Thus, this embodiment employs turntable motor 10 to provide smoother, less noisy operation of turntable motor assembly 100.
In one embodiment, the eccentric 11 rotates and reverses to rotate in the range of 0-90 degrees; the rotation directions of the two turntable motors 10 are opposite, and the two turntable motors 10 collide with the stopper 4 at the same time. The maximum rotation angle of the eccentric 11 is 90 °, and after the rotation of 90 ° is stopped by collision with the stopper 4, the rotation can be reversely rotated by 90 ° to again stop by collision with the stopper 4. The two turntable motors 10 are identical in structure, and have the same rotation speed and torque, but opposite rotation directions, and the opposite rotation directions of the two turntable motors 10 refer to: the case where one turntable motor 10 rotates clockwise and the other turntable motor 10 rotates counterclockwise does not occur, referring to fig. 8 and 12, and the two turntable motors 10 collide with the corresponding stopper 4 at the same time, and the collision force occurs at the same time, and the centrifugal force disappears at the time of collision, leaving only the component in the y direction.

The eccentric wheel 11 may be a semicircular wheel, the central angle of the semicircular wheel is 180 degrees, the second limiting surface 42 and the first limiting surface 41 are vertically arranged to be 90 degrees, and thus the rotation and reverse rotation angle ranges of the eccentric wheel 11 can be limited to be 0-90 degrees, and asymmetric vibration can be generated.

In this way, the movements of the two eccentric wheels 11 are not affected by each other, compared to the case of only one stop 4, and the vibrations generated by one eccentric wheel 11 do not affect the other eccentric wheel 11 when the two eccentric wheels 11 simultaneously collide with one stop 4.
In an embodiment, each limiting member 4 includes a first limiting surface 41, a second limiting surface 42, and a guiding surface 43 connecting the first limiting surface 41 and the second limiting surface 42, each eccentric wheel 11 includes a first abutting surface 13 and a second abutting surface 14, the first abutting surface 13 is used for abutting against the first limiting surface 41, the second abutting surface 14 is used for abutting against the second limiting surface 42, the first limiting surface 41 and the second limiting surface 42 are vertically arranged, a perpendicular bisector of a central connecting line of the two rotating shafts 12 is used as a symmetrical line, and the two limiting members 4 are arranged in a mirror image mode relative to the symmetrical line.

The center of the rotating shaft 12, namely the rotation center of the eccentric wheel 11, connects the centers of the two rotating shafts 12 to form a line segment, namely the center connecting line of the rotating shaft 12, takes the perpendicular bisector, namely the perpendicular bisector, of the line segment as a symmetrical line, and the two limiting parts 4 are arranged in a mirror image mode relative to the symmetrical line, so that the two eccentric wheels 11 can be guaranteed to collide with the limiting parts 4 at the same time, and the centrifugal force disappears when the two eccentric wheels 11 collide with the limiting parts 4 at the same time, and only the component in the y direction is left.

The density of the mass member 1112 is much larger than that of the permanent magnet, and the mass of the mass member 1112 is set to be larger than that of the permanent magnet when the mass member 1112 is set, so that the vibration feeling can be increased by setting the mass member 1112.

Referring to fig. 7 and 8, fig. 7 shows that the eccentric 1111 rotates 90 ° to collide with the stopper 45, and fig. 8 shows a schematic diagram of resultant force applied to the turntable motor unit 100 when the collision occurs, and centrifugal force disappears when the collision occurs, and braking forces in-y directions are generated, respectively.
Referring to fig. 9 and 10, fig. 9 shows a schematic diagram of reverse rotation after the eccentric 1111 is braked, wherein the left turntable motor 10 rotates clockwise, the right turntable motor 10 rotates counterclockwise, and fig. 10 shows a schematic diagram of resultant force applied to the reverse rotation turntable motor assembly 100, wherein the x components of the torque and centrifugal force of the two eccentric movers 1 are cancelled, leaving the y component;
referring to fig. 11 and 12, fig. 11 shows that the eccentric 1111 is braked and then reversely rotated by 90 ° and returns to the initial position, and the brake collides with the stopper 45, and fig. 12 shows a schematic diagram of resultant force applied to the turntable motor unit 100 when the reverse rotation is braked, and at this time, centrifugal force is eliminated and braking forces of the movers of the turntable motors 10 cancel each other.
Since the eccentric mover 1 is provided, the vibration generated during rotation and braking is asymmetric vibration. Referring specifically to fig. 13, a curve a in fig. 13 shows an electrical signal input by the motor, a curve B in fig. 13 shows an acceleration signal acquired by the acceleration sensor for the turntable motor assembly 100, an abscissa shows time, a left ordinate shows an input voltage magnitude, and a right ordinate shows an acceleration magnitude. It can be seen that the absolute values of the electrical signals input by the motors are substantially the same, but the acceleration values of the turntable motor assembly 100 are different, and the waveforms of the acceleration signals are asymmetrically distributed, so that the turntable motor assembly 100 is said to generate asymmetric vibrations.
According to another aspect of the present application, there is also provided an electronic device including a housing and a turntable motor assembly 100 as described above disposed within the housing. Because the electronic device includes all the technical solutions of all the embodiments of the turntable motor assembly 100, all the beneficial effects of all the technical solutions described above are not described in detail herein. The electronic device may be a mobile phone or a game pad.
