Description

Technical Field

[0001] The present invention relates to the technical field of motor structures, and in particular to a motor stator and rotor structure and a motor. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (also known as the stator winding) to generate a rotating magnetic field and act on the rotor to form a magneto-electrodynamic rotating torque. The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized conductor in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field direction). The working principle of the motor is that the magnetic field acts on the current to force the motor to rotate.

[0003] When the existing motor structure is working, the motor itself will generate a certain amount of heat due to the current. The temperature rise of the motor is particularly serious when the load is large. Therefore, the heat dissipation problem is generally taken into consideration when designing the motor. For example, Chinese patent publication number CN117614162A discloses a motor stator and rotor structure and a motor. In the technical solution disclosed in this patent document, the heat inside the motor is released to the outside by adding a metal heat-conducting ring and a heat exchanger on the motor casing that can contact the stator core inside the motor. However, the contact area between the metal heat-conducting ring and the stator core is limited. At the same time, the contact with the stator core through the external heat sink can easily reduce the position stability of the stator core inside the motor, which has a certain impact on the normal output torque of the motor. Not only can the heat dissipation effect of the motor itself not be guaranteed, but it will also affect the normal output of the motor. In view of this, we propose a motor stator and rotor structure and a motor. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a motor stator and rotor structure and a motor, which have the following beneficial effects:

[0017] 1. By providing a heat dissipation structure, when the motor starts and drives the motor stator and rotor structure to rotate, the gear ring is driven to rotate. At this time, the gear ring cooperates with the transmission of the gear sleeve, causing the gear sleeve to rotate on the inner wall of the transmission cavity. Under the influence of the transmission ball and the wave groove, the movable rod installed inside the gear sleeve will move back and forth slightly in the horizontal direction. In turn, the spoiler assembly cooperates to cause the heat transfer oil filled in the heat dissipation cavity to flow, so that the heat transfer oil can more quickly dissipate the heat in the casing and ensure the stable operation of the motor stator and rotor structure.

[0018] 2. By providing a spoiler assembly, when the movable rod moves within the heat dissipation cavity, it is affected by the resistance of the thermal oil, causing the spoiler and rotating block to rotate randomly within the mounting sleeve. The restriction of the restriction bar and the restriction groove prevents the spoiler from rotating continuously 360 degrees. By rotating at a certain angle, the spoiler can better influence the thermal oil, causing it to flow within the heat dissipation cavity, thereby improving the heat dissipation effect on the motor stator and rotor structure within the casing and ensuring its normal operation.

[0019] 3. By providing a connecting component, cooperating with an arcuate groove forming an inclined curved groove on the arcuate inner wall of the casing, and a plurality of arcuate blocks provided on the inner wall of the arcuate groove, the size of the air gap between the motor stator and rotor structure and the casing on the inner surface of the casing is increased, so that flowing air can remove heat from the surface of the motor stator and rotor structure, thereby achieving a cooling and heat dissipation effect. At the same time, the arcuate outer surface of the arcuate block can disturb the airflow flowing through the arcuate groove, thereby improving the heat dissipation efficiency of the motor stator and rotor structure, ensuring that the left and right sides of the motor stator and rotor structure can maintain a good ventilation state, and cooperate with the rotation of the fan to achieve heat dissipation and cooling of the motor stator and rotor structure.

[0020] 4. By providing an external heat sink assembly, along with internal grooves on the side of the metal ring and several curved protrusions on its curved inner surface, the contact area between the metal ring and the thermal oil in the heat sink cavity is greatly increased. This improves heat dissipation from the metal ring, the external heat sink ring, and the heat sink fins, thereby increasing the heat dissipation efficiency of the thermal oil in the heat sink cavity and ensuring the heat dissipation requirements of the motor stator and rotor structure within the housing, thereby ensuring normal operation of the motor.

A gear ring 54 is coaxially fixedly installed on the stator and rotor structure 4 of the motor. A gear sleeve 55 is rotatably installed on the inner wall of the end of the transmission cavity 52. A movable rod 56 is movably installed inside the gear sleeve 55. A wave groove 57 is provided on the arc-shaped inner wall of the gear sleeve 55. A transmission ball 58 is fixedly installed on the arc-shaped outer wall of the movable rod 56. The transmission ball 58 is arranged inside the wave groove 57. A turbulent component 6 that can drive and turbulent the heat transfer oil in the heat dissipation cavity 51 is provided on the arc-shaped outer wall of the movable rod 56.

[0034] Furthermore, filter screens are provided at both ends of the casing 1 to ensure the overall ventilation effect of the casing 1, and the filter screens are waterproofed to prevent water in the external environment from directly entering the interior of the casing 1 and affecting the normal operation of the motor stator and rotor structure 4. At the same time, the heat dissipation cavity 51 is arranged in a circular ring shape on the vertical central axis of the casing 1, and the width of the heat dissipation cavity 51 is adapted to the motor stator and rotor structure 4, so as to provide a sufficiently large heat exchange contact area for the motor stator and rotor structure 4 to better meet the heat dissipation requirements of the motor stator and rotor structure 4. In addition, an annular groove is provided between the transmission cavity 52 and the internal cavity of the casing 1, and the gear ring 54 includes a sleeve and a gear ring and a connecting plate fixedly connected between the sleeve and the gear ring, and the sleeve and the motor stator and rotor The structures 4 are socketed to achieve that the motor stator and rotor structure 4 can drive the socket tube to rotate synchronously when outputting power to the outside. Specifically, the width of the annular groove is adapted to the width of the connecting plate, and the gear ring is arranged inside the transmission cavity 52, thereby ensuring the stable transmission of the gear ring 54.

[0035] In addition, the gear ring 54 meshes with the gear sleeve 55 to realize transmission. At the same time, the number of gear sleeves 55 is provided in multiple groups, and the multiple groups of gear sleeves 55 are evenly distributed in a circular array inside the transmission cavity 52. Specifically, a circular hole with a diameter matching the outer diameter of the movable rod 56 is provided on the inner wall of the heat dissipation cavity 51, and the movable rod 56 is arranged in the circular hole. Specifically, a part of the movable rod 56 is arranged in the transmission cavity 52, and the other part is arranged in the heat dissipation cavity 51. Further, a circular hole with an outer diameter matching the outer diameter of the movable rod 56 is provided on the inner wall of the spiral belt 53, and the movable rod 56 is arranged in the circular hole. At the same time, a straight bar is provided on the outer surface of the movable rod 56 at the internal position of the circular hole, and a straight groove matching the straight bar is provided on the inner wall of the circular hole, so that The movable rod 56 passes through the transmission cavity 52, the heat dissipation cavity 51 and the spiral belt 53 at the same time, and limits the movable rod 56 to move only in the horizontal direction. Specifically, when the motor is started and the motor stator and rotor structure 4 is driven to rotate, the gear ring 54 is driven to rotate. At this time, the gear ring 54 transmits the gear sleeve 55, so that the gear sleeve 55 rotates on the inner wall of the transmission cavity 52. Affected by the transmission ball 58 and the wave groove 57, the movable rod 56 installed in the gear sleeve 55 will move back and forth slightly in the horizontal direction, and then cooperate with the spoiler component 6 to make the heat transfer oil filled in the heat dissipation cavity 51 flow, so that the heat transfer oil can dissipate the heat in the casing 1 more quickly, thereby ensuring the stable operation of the motor stator and rotor structure 4.

[0036] In an embodiment of the present invention, the spoiler assembly 6 includes a mounting sleeve 61, a mounting groove is provided on the curved outer wall of the movable rod 56, the inner wall of the mounting groove is fixedly installed with the mounting sleeve 61, the inner wall of the mounting sleeve 61 is rotatably connected to a rotating block 62, the top of the rotating block 62 is fixedly connected to a spoiler 63, the inner wall of the mounting sleeve 61 is provided with a limiting groove 64, and a limiting bar 65 is fixedly installed on the curved outer wall of the rotating block 62.

[0037] Specifically, the number of spoiler assemblies 6 is provided in multiple groups, and each group of spoiler assemblies 6 includes two mounting sleeves 61 and rotating blocks 62, and the two mounting sleeves 61 and rotating blocks 62 are symmetrically arranged on the upper and lower sides of the movable rod 56 with the horizontal central axis of the movable rod 56 as the symmetry axis, and the spoilers 63 corresponding to the two rotating blocks 62 are arranged in parallel with each other to enhance the guiding and spoiling effect of the spoiler assembly 6 on the heat transfer oil in the heat dissipation cavity 51. At the same time, multiple groups of spoiler assemblies 6 are arranged in a linear array on the arc-shaped outer wall of the movable rod 56, and the spoiler assembly 6 is arranged in the gap of the spiral belt 53 to enhance the influence of the spoiler assembly 6 on the heat transfer oil. Furthermore, a quadrilateral groove is provided at the center of the spoiler 63. To prevent the spoiler 63 from being damaged by excessive resistance, at the same time, the limiting groove 64 is arranged in an arc shape, and the limiting bar 65 is adapted to the limiting groove 64. When the movable rod 56 moves inside the heat dissipation cavity 51, it is affected by the resistance of the heat transfer oil, so as to cause the spoiler 63 and the rotating block 62 to rotate disorderly inside the mounting sleeve 61. The limiting bar 65 and the limiting groove 64 limit the spoiler 63 to avoid continuous 360-degree rotation. By rotating at a certain inclination angle, the spoiler 63 can better affect the heat transfer oil, causing it to flow in the heat dissipation cavity 51, so as to enhance the heat dissipation effect on the stator and rotor structure 4 of the motor in the casing 1, and ensure its normal working effect.

[0038] In an embodiment of the present invention, the stator and rotor structure 4 of the motor includes a stator core 41, the stator core 41 is fixedly installed on the inner wall of the casing 1, a rotating rod 43 is rotatably installed on the inner wall of the casing 1, the rotating rod 43 passes through and is fixedly connected to the rotor core 42, a bearing 44 is fixedly installed on the inner wall of the end of the casing 1, the inner ring of the bearing 44 is fixedly connected to the rotating rod 43, a sleeve 45 is rotatably installed on the inner wall of the end of the casing 1 away from the bearing 44, and a fan 46 is fixedly connected to the end of the sleeve 45.

[0039] It is worth noting that the stator core 41 is detachably mounted on the inner wall of the casing 1 by means of L-shaped fasteners, and the rotor core 42 is arranged at the center of the stator core 41, and the two are arranged coaxially. At the same time, a cross connecting block is fixedly mounted on the outer wall of the end of the rotating rod 43 close to the sleeve 45, and a cross connecting groove adapted to the cross connecting block is provided on the inner wall of the end of the sleeve 45 away from the fan 46. When the motor is assembled, the cross connecting block is inserted into the cross connecting groove to enable docking between the rotating rod 43 and the sleeve 45. When the motor is started, the rotor core 42 drives the rotating rod 43 to rotate, and then drives the sleeve 45 and the fan 46 to rotate. The fan 46 is arranged in the gap between the protective cover 3 and the end of the casing 1 to generate a continuous airflow and thereby realize air cooling of the internal space of the casing 1, thereby ensuring that the stator and rotor structure 4 of the motor is in a normal working state.

[0040] Furthermore, the interior of the casing 1 is provided with a connecting component 7 that can increase the heat dissipation contact area of the stator and rotor structure 4 of the motor. The connecting component 7 includes an arc groove 71. The arc groove 71 is provided on the arc inner wall of the casing 1. An arc block 72 is provided on the bottom inner surface of the arc groove 71. Specifically, the arc groove 71 is arranged in a curve to form an inclined curved groove on the arc inner wall of the casing 1, thereby increasing the size of the leakage area between the motor stator and rotor structure 4 and the casing 1 on the inner surface of the casing 1, so that the flowing air can take away the heat from the surface of the motor stator and rotor structure 4, thereby dissipating the heat. To achieve the cooling and heat dissipation effect, at the same time, the number of arc blocks 72 is set to be several, and the several arc blocks 72 are evenly distributed on the bottom inner surface of the arc groove 71. On the one hand, the setting of several arc blocks 72 can make up for the overall strength of the casing 1 at this position after the arc groove 71 is opened. At the same time, its arc-shaped outer surface can disturb the airflow flowing in the arc groove 71 to improve the heat dissipation efficiency of the motor stator and rotor structure 4, so that the left and right sides of the motor stator and rotor structure 4 can maintain a good ventilation state, so as to cooperate with the rotation of the fan 46 to achieve heat dissipation and cooling of the motor stator and rotor structure 4.

[0041] At the same time, the outer surface of the casing 1 is provided with an external heat dissipation component 8 for quickly dissipating the heat of the stator and rotor structure 4 of the motor inside the casing 1. The external heat dissipation component 8 includes a heat dissipation ring 81. The heat dissipation ring 81 is fixedly installed on the arc-shaped outer wall of the casing 1. A plurality of heat dissipation fins 82 are fixedly installed on the arc-shaped outer surface of the heat dissipation ring 81. A metal ring 83 is fixedly installed on the arc-shaped inner surface of the heat dissipation ring 81. An inner groove 84 is provided on the side of the metal ring 83. A through hole 85 is provided at the center of the inner groove 84. A plurality of arc-shaped protrusions 86 are provided on the arc-shaped inner surface of the metal ring 83.

[0042] Specifically, the external heat dissipation component 8 is arranged on the vertical central axis of the casing 1. At the same time, a ring groove with a width that matches the width of the metal ring 83 is opened on the arc-shaped outer wall of the heat dissipation cavity 51, so that the heat dissipation ring 81 placed outside the casing 1 can extend into the heat dissipation cavity 51 through the metal ring 83 to better achieve heat transfer. At the same time, there are two groups of inner grooves 84, and the two groups of inner grooves 84 are mirror-imaged on the left and right sides of the metal ring 83, and the metal ring 83 can be made of copper sheets to better achieve heat conduction, thereby facilitating the heat dissipation of the motor stator and rotor structure 4 inside the casing 1. In addition, the inner groove 84 is arranged in an arc shape, and the through hole 85 is arranged in the inner groove 8 4 is the narrowest part to ensure that the heat-conducting oil in the left and right parts of the heat-dissipating cavity 51 can also circulate, and will not generate large lateral stress on the metal ring 83, causing damage to it and affecting the overall sealing of the heat-dissipating cavity 51. By providing an inner groove 84 on the side of the metal ring 83 and providing a plurality of arc-shaped protrusions 86 on its arc-shaped inner surface, the contact area between the metal ring 83 and the heat-conducting oil in the heat-dissipating cavity 51 is greatly increased, thereby improving the heat dissipation of the metal ring 83 and the external heat-dissipating ring 81 and the heat-dissipating fins 82 to the outside, so as to improve the heat dissipation efficiency of the heat-conducting oil in the heat-dissipating cavity 51, ensure the heat dissipation requirements of the motor stator and rotor structure 4 inside the casing 1, and thus ensure the normal operation of the motor.

[0043] In the present invention, when the motor is powered on and started, the magnetic field generated by the stator core 41 after being powered on causes the rotor core 42 at the axis of the stator core 41 to drive the rotating rod 43 to rotate at high speed, and causes the rotating rod 43 to output a rotational torque to the outside of the housing 1 through the bearing 44. When the stator rotating rod 43 rotates at high speed, it will synchronously drive the sleeve 45 and the fan 46 to rotate, so as to generate an airflow from right to left inside the housing 1, so as to achieve heat dissipation for the stator and rotor structure 4 of the motor set in the housing 1. At the same time, the rotating rod 43 The rotation will drive the gear ring 54 to rotate synchronously. At this time, the gear ring 54 transmits the gear sleeve 55, so that the gear sleeve 55 rotates on the inner wall of the transmission cavity 52. Affected by the transmission ball 58 and the wave groove 57, the movable rod 56 installed inside the gear sleeve 55 will move back and forth slightly in the horizontal direction, and then cooperate with the spoiler component 6 to make the heat transfer oil filled in the heat dissipation cavity 51 flow, so that the heat transfer oil can dissipate the heat in the casing 1 more quickly, ensuring the stable operation of the stator and rotor structure 4 of the motor.
