Description

Technical Field

[0001] The present application relates to the technical field of motors, and in particular to a strong magnetic field motor with improved performance. Background Art

[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Magnetic concentration technology refers to the ingenious use of various arrangements of permanent magnets and magnetic conductors to gather as much magnetic flux as possible into the working air gap, that is, to increase the magnetic flux density of the air gap in the magnetic circuit, thereby improving the output and rapid response of the motor.

[0003] The Chinese patent with the relevant authorization announcement number CN204947759U discloses a magnetically concentrated permanent magnet motor, which is composed of a stator, a rotor, a bearing, and a control system. The stator is composed of a core shaft and a coil wound on a pole shoe on the core shaft. There are several pole shoes, which are evenly distributed along the circumference; the rotor is composed of a permanent magnet assembly fixed on the inner circle of a magnetic conductive cylinder. The permanent magnet assembly aggregates magnetic force to form strong exposed magnetic poles. The exposed magnetic poles of the permanent magnet assembly face the axis of the rotor. The number of exposed magnetic poles is the same as that of the pole shoes of the stator. The exposed magnetic poles are evenly distributed along the inner circle of the rotor and the polarities of adjacent exposed magnetic poles are opposite; the rotor is installed outside the stator with a gap, the two are coaxial, the rotor and the stator are connected by bearings, the coils on the pole shoes are connected to the control system, and the control system is connected to an external power supply; during operation, the control system alternately passes current in positive and negative directions into the coil to generate magnetic attraction or repulsion with the exposed magnetic poles to drive the rotor to rotate in the positive direction, and strong magnetic poles have been formed by the aggregation of magnetic force by the permanent magnet assembly, thereby improving the working efficiency of the motor.

[0004] With respect to the above-mentioned related technologies, the inventors believe that as the working efficiency of the motor is improved by increasing the magnetic field gathering capacity, the heat generated by the long-term rotation of the motor rotor will also increase. A large amount of heat will accumulate and cannot be discharged quickly and effectively, which will easily reduce the performance of the motor. Summary of the invention

[0005] In order to solve the technical problem in the related art that the heat generated during the operation of the motor cannot be dissipated quickly and effectively, thereby affecting the performance of the motor, the present application provides a strong magnetic field motor with improved performance.

[0006] The present application provides a strong magnetic focusing motor with improved performance, which adopts the following technical solution:

[0007] A strong magnetic motor with improved performance comprises a shell and a back cover, wherein a rotating shaft is rotatably connected inside the shell; a cavity is arranged inside the shell, and a plurality of cooling fans are rotatably connected to the inner wall of the shell, a docking hole for inserting the cooling fan is formed through the inner wall of the cavity, and a ventilation hole connected to the cavity is formed through the side wall of the shell; a cooling pipe is arranged inside the cavity, and a cooling liquid is contained in the cooling pipe; one end of the cooling pipe is fixedly connected to the end of the rotating shaft, and an internal gear is sleeved on the side wall of the cooling pipe near the cooling fan, and the cooling fan comprises a rotating rod, which is rotatably connected to the inner wall of the shell, and an external gear for meshing with the internal gear is fixedly sleeved on the outer wall of the rotating rod.

[0008] By adopting the above technical solution, when the motor is working, the shaft rotates circumferentially, and the cooling pipe makes a circular motion along the circumference of the shaft. During the rotation of the cooling pipe, the inner gear and the outer gear engage with each other to drive the cooling fan to rotate. The cooling fan promotes the circulation of air inside and outside the outer casing, and the cooling pipe is filled with coolant to cool the air passing through the cavity, thereby quickly dissipating the heat generated during the operation of the motor and ensuring the applicability of the motor.

[0009] Optionally, the heat dissipation fan further includes a blade group fixedly connected to the outer side wall of the rotating rod, and the blade group is composed of a plurality of heat dissipation aluminum sheets.

[0010] By adopting the above technical solution, the aluminum heat sink has mass and can rotate under the drive of the rotating rod, and the aluminum heat sink has the characteristic of fast heat dissipation. Therefore, using the heat sink aluminum fins as the blades of the cooling fan can further optimize the heat dissipation effect of the cooling fan and accelerate the dissipation of heat.

[0011] Optionally, a dust filter is provided on the outer wall of the shell near each of the ventilation holes.

[0012] By adopting the above technical solution, the setting of the dust filter can reduce the external dust from entering the shell through the ventilation holes, thereby causing the internal structure of the motor to be covered with dust, and then causing the normal operation of the motor, so as to further ensure the stable operation of the motor.

[0013] Optionally, the dust filter includes a docking frame and a hemispherical filter fixedly connected to the docking frame, one end of the docking frame away from the hemispherical filter is connected to the inner wall of the ventilation hole, and the outer surface of the hemispherical filter protrudes from the outside of the shell.

[0014] By adopting the above technical solution, since the outer surface of the hemispherical filter protrudes from the outside of the outer shell, dust falling on the outer surface of the hemispherical filter can fall under the guidance of the outer surface, thereby reducing the accumulation of external dust on the outer surface of the hemispherical filter, thereby reducing the possibility of clogging of the hemispherical filter.

[0015] Optionally, a cleaning brush is provided on the side wall of the internal gear facing away from the cooling fan, and the side wall of the hemispherical filter facing the cavity is in contact with the outer surface of the cleaning brush.

[0016] By adopting the above technical solution, when the cooling pipe rotates circumferentially driven by the rotating shaft, the cleaning brush on the cooling pipe will scrape the outer surface of the hemispherical filter to clean the outer surface of the hemispherical filter, thereby further reducing the possibility of clogging of the hemispherical filter.

[0017] Optionally, the docking frame is threadedly connected to the ventilation hole.

[0018] By adopting the above technical solution, by driving the docking frame to be threadedly connected in the ventilation hole, on the one hand, a detachable connection of the docking frame is realized, so that it is convenient to regularly disassemble the dust filter for replacement and cleaning; on the other hand, when the outer surface of the cleaning brush is worn and cannot fit on the outer surface of the hemispherical filter, the docking frame can be screwed into one end of the ventilation hole close to the cavity, that is, the dust filter is driven to move in the direction close to the cleaning brush, so as to ensure that the cleaning brush can fit on the outer surface of the hemispherical filter, thereby ensuring the cleaning effect of the cleaning brush on the hemispherical filter.

[0019] Optionally, a base is provided under the shell, a mounting groove for inserting the shell is provided on the base, a shock-absorbing pad is provided on the inner wall of the mounting groove, and the shock-absorbing pad is fixedly connected to the outer surface of the shell.

[0020] By adopting the above technical solution, the shock-absorbing pad can be a rubber pad. The setting of the shock-absorbing pad can reduce the conduction of vibration generated by the motor during operation, thereby reducing the noise generated by the vibration and improving the stability of the motor during operation.

[0021] Optionally, a plurality of through holes are formed through the side wall of the shock absorbing pad, and a connecting hole for communicating with the through holes is formed on the side wall of the base.

[0022] By adopting the above technical solution, when the contact surface between the shell and the shock absorbing pad generates heat due to mutual contact and friction, since the through hole and the connecting hole are connected, the heat can be dissipated, reducing the heat accumulation between the shock absorbing pad and the shell, thereby further playing a heat dissipation role.

[0023] Optionally, a connecting pad is integrally formed on the side wall of the shock-absorbing pad near each through hole, a connecting hole connected to the through hole is opened on the connecting pad, a spring is arranged in the through hole, and an end of the spring is fixedly connected to the connecting pad at a corresponding position.

[0024] By adopting the above technical solution, the arrangement of the spring, the connecting pad and the connecting hole can support the shock absorbing pad near the through hole without affecting the deformation and heat dissipation of the shock absorbing pad, thereby achieving stable support of the shock absorbing pad to the shell.

[0025] Optionally, a silencer cavity is arranged inside the shell along its circumference, and silencer cotton is arranged in the silencer cavity.

[0026] By adopting the above technical solution, the setting of the silencer cotton can further reduce the noise generated during the operation of the motor and optimize the working environment.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When the shaft rotates circumferentially, the cooling tube moves in a circular motion along the shaft. During the rotation of the cooling tube, the inner gear meshes with the outer gear to drive the cooling fan to rotate. The cooling fan promotes the circulation of air inside and outside the shell. The cooling tube is filled with coolant to cool the air passing through the cavity, so as to quickly dissipate the heat generated during the operation of the motor and ensure the applicability of the motor.

[0029] 2. When the cooling pipe rotates in the circumferential direction driven by the rotating shaft, the cleaning brush on the cooling pipe will scrape the outer surface of the hemispherical filter to clean the outer surface of the hemispherical filter, thereby further reducing the possibility of clogging of the hemispherical filter;

[0030] 3. The setting of the shock-absorbing pad can reduce the propagation of the vibration generated during the operation of the motor. In addition, the setting of the silencer cotton can reduce the propagation of the noise generated during the operation of the motor. BRIEF DESCRIPTION OF THE DRAWINGS
