Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a magnetic two-wire motor. Background Art

[0002] The traditional motor consists of a stator and a rotor. Specifically, the stator includes a stator core and a coil assembly inserted on the stator core, and the stator core is provided with a mounting hole; the rotor is inserted into the mounting hole, and the rotor includes a rotor core and a permanent magnetic force arranged on the rotor core. However, the current motor does not have a constant force to maintain directional rotation, so it needs to be improved. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a magnetic two-wire motor, which has the advantage of directional rotation.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a magnetic two-wire motor, comprising a shell, a gear set and an output gear, the shell comprising a partition and an output shaft that can rotate around its own axis, the output shaft is sleeved with a first gear, the first gear is meshed with a second gear, a first rotating shaft is arranged in the middle of the second gear, a brake pad on the other side of the partition is movably sleeved below the first rotating shaft, the output shaft is integrally connected with a baffle equidistantly distributed about the axis of the output shaft, the partition is provided with a through groove that penetrates the partition, and the brake pad is integrally connected with a brake block in the through groove.

[0005] By adopting the above technical solution, the rotation of the output shaft can drive the gear set to rotate and then drive the output gear to rotate, thereby realizing the transmission of the entire motor. In this process, the rotation of the first gear will drive the rotation of the second gear, and the rotation of the second gear will drive the first rotating shaft to rotate, thereby driving the brake pad to rotate in the direction away from the output shaft, and the brake pad drives the brake block to rotate in the direction away from the output shaft. The brake block is always in the through groove, thereby limiting the brake pad from continuing to rotate. In this process, the brake pad is not fixedly connected to the first rotating shaft, so the two will rotate relative to each other. At this time, the brake pad will not interfere with the rotation of the output shaft. When the output shaft rotates in the opposite direction, the output shaft will drive the first gear to rotate and then drive the second gear to rotate. The rotation of the second gear will drive the first rotating shaft to rotate and then drive the brake pad to rotate in the direction of the output shaft. The brake pad will move to the side of the output shaft and be between the two baffles. The output shaft is restricted and cannot rotate, thereby achieving the purpose of directional rotation.

[0006] The utility model is further configured as follows: the output shaft is connected to a first magnetic steel, the output shaft is sleeved with a fixed sleeve, a third gear is integrally connected to the top of the fixed sleeve, the fixed sleeve is clamped with a magnetic conductive sheet sleeved outside the first magnetic steel, the output shaft is passed through the center of the third gear, the third gear is meshed with a plurality of planetary gears, and the plurality of planetary gears are meshed with the same fourth gear.

[0007] By adopting the above technical solution, the fixed sleeve can rotate relative to the output shaft in the circumferential direction of the output shaft, and the output shaft will drive the first magnetic steel to rotate. At this time, the output shaft will not allow the fixed sleeve to rotate, thereby allowing the first magnetic steel to generate a magnetic field. The magnetic conductive sheet will rotate under the action of the magnetic field and then drive the fixed sleeve to rotate. The rotation of the fixed sleeve will drive the rotation of the third gear and then drive the rotation of multiple planetary gears. The multiple planetary gears jointly drive the rotation of the fourth gear, thereby achieving the partial transmission purpose of the gear set. It is worth noting that the magnetic conductive sheet does not contact the first magnetic steel during this process. A permanent magnet is fixed on the driving gear shaft in the planetary gear set. Its polarity is opposite to the direction of the permanent magnet in the motor, and the two attract each other. Its rotation direction is synchronized with the rotation direction of the motor. When the motor is powered on, the driving gear drives the planetary set to run. When the driving gear in the planetary gear set runs to a certain angle, the baffle on the driving gear shaft hits the brake pad under the first rotating shaft, and the entire gear set stops working, but the motor is still running normally. At this time, the permanent magnet fixed on the driving gear shaft acts as a clutch. Regardless of whether the motor runs clockwise or counterclockwise, the first magnet and the second magnet are attracted, and the operating power of the gear set comes from this attraction. When the gear set is blocked, but the motor can run, the first magnet at this time acts as a clutch.

[0008] The utility model is further configured as follows: the fourth gear is meshed with the fifth gear, the middle part of the fifth gear is fixedly connected with the third rotating shaft, the third rotating shaft is sleeved with the sixth gear located below the fifth gear, the sixth gear is meshed with the seventh gear, the seventh gear is fixedly connected with the fourth rotating shaft, and the fourth rotating shaft is sleeved with the output gear located above the seventh gear.

[0009] By adopting the above technical solution, the rotation of the fourth gear can drive the fifth gear to rotate and then drive the third rotating shaft to rotate, the rotation of the third rotating shaft can drive the sixth gear to rotate and then drive the seventh gear to rotate, the rotation of the seventh gear can drive the fourth rotating shaft to rotate and then drive the output gear to rotate, thereby realizing the rotation of the entire gear set.

[0010] In summary, the utility model has the following beneficial effects:

[0011] The rotation of the output shaft can drive the first gear to rotate, the rotation of the first gear will drive the second gear to rotate and then drive the first rotating shaft to rotate, the rotation of the first rotating shaft will drive the brake pad to rotate, so the brake pad rotates synchronously with the second gear. After the brake pad rotates to the first gear with the second gear, the brake pad will squeeze the second gear to play a braking role. The brake pad is between the first gear and the brake block.
