As shown in fig. 1 and 2, in an embodiment of the present invention, a motor base 100 is provided, where the motor base 100 includes a first housing 110, a second housing 120, and a guide vane 130, the second housing 120 is disposed around the outside of the first housing 110, the first housing 110 and the second housing 120 are disposed at intervals in a radial direction, the guide vane 130 is located between the first housing 110 and the second housing 120, and the guide vane 130 is used for guiding an airflow; the guide vanes 130 are provided with a plurality of guide vanes 130, the plurality of guide vanes 130 are distributed at intervals along the circumferential direction of the first shell 110, two radially opposite sides of each guide vane 130 are respectively connected to the first shell 110 and the second shell 120, the adjacent guide vanes 130 define a first air channel 140, and air flow entering the first air channel 140 is blown out along the axial direction under the guidance of the guide vanes 130. Further, the guide vane 130 includes a first wind guiding portion 131 and a second wind guiding portion 132, at least a portion of the first wind guiding portion 131 and at least a portion of the second wind guiding portion 132 are spaced apart along the circumferential direction of the first casing 110, and define a wind guiding cavity 133.
In general, the air flow is guided by the guide vane 130 to gradually flow from the air inlet side to the air outlet side, when the speed of the air flow is high, the air flow is not easy to change, an air compression area is easy to generate in the area of the leeward side of the guide vane 130, which is close to the air outlet 160, turbulence is easy to generate in the air compression area, the collision between the air flow and the guide vane 130 is increased, and the impact loss generated by the air flow in the first air duct 140 results in the reduction of the wind pressure and the wind speed of the air flow at the air outlet 160. From this, in this application's embodiment, through dividing into two parts with the stator 130 in circumference, have wind-guiding chamber 133 between first wind-guiding portion 131 and the second wind-guiding portion 132, the distance between two sides in the circumference of stator 130 has been increaseed, the holistic structural strength of stator 130 improves, can reduce the vibration of stator 130 when the air current collides, be favorable to reducing the noise, and the region that the leeward side of stator 130 is close to air outlet 160 is closer to the region that the air inlet side of adjacent stator 130 is close to air outlet 160, can reduce the turbulent flow of air-pressure district and air current, reduce the energy loss of air current in first wind channel 140, thereby can improve the wind pressure and the wind speed of fan.
After the high-speed airflow enters the first air duct 140, the high-speed airflow contacts the windward side of the guide vane 130 at first and gradually flows along the axial direction under the guiding of the guide vane 130, according to an embodiment of the present invention, as shown in fig. 3, the first wind guiding portion 131 is located on the windward side of the guide vane 130, and the thickness of the first wind guiding portion 131 in the circumferential direction of the first housing 110 is greater than the thickness of the second wind guiding portion 132 in the circumferential direction of the first housing 110; by increasing the thickness of the windward side of the guide vane 130, the vibration of the first wind guiding portion 131 caused when the high-speed airflow impacts the first wind guiding portion 131 can be reduced, which is beneficial to reducing noise.
As shown in fig. 4, an air inlet 150 and an air outlet 160 are defined between two ends of the first housing 110 and the second housing 120, two ends of the first air duct 140 are respectively communicated with the air inlet 150 and the air outlet 160, and air flow enters the first air duct 140 through the air inlet 150, is discharged from the air outlet 160 under the guidance of the guide vane 130 positioned in the first air duct 140, and flows along the axial direction.
In one embodiment, as shown in fig. 3, one ends of the first air guiding portion 131 and the second air guiding portion 132 facing the air inlet 150 are attached to each other in the circumferential direction of the first housing 110, and one ends of the first air guiding portion 131 and the second air guiding portion 132 facing the air outlet 160 are spaced from each other in the circumferential direction of the first housing 110. Therefore, the air guiding cavity 133 is closed at one side facing the air inlet 150, so that turbulent flow is prevented from being formed when air flows enter the air guiding cavity 133, energy loss of the air flows is caused, the whole thickness of the guide vane 130 at one side of the air outlet 160 is increased, an air compression area and turbulent flow can be reduced, and the air pressure and the air speed of the air flows are improved.
In another embodiment, along the direction of the air inlet 150 toward the air outlet 160, the distance between the surfaces of the first air guiding portion 131 and the second air guiding portion 132 facing away from each other in the circumferential direction of the first housing 110 is gradually increased, so that the thickness of the guide vane 130 on the air outlet side is increased, and the air compression area of the guide vane 130 and the air flow energy loss caused by turbulence are effectively reduced. Note that, the change in the distance between the surfaces of the first air guiding portion 131 and the second air guiding portion 132 facing away from each other may be that the thicknesses of the first air guiding portion 131 and the second air guiding portion 132 are the same, and the distance between the surfaces of the first air guiding portion 131 and the second air guiding portion 132 facing close to each other increases; alternatively, the distance between the surfaces of the first air guiding part 131 and the second air guiding part 132 that are close to each other and the thickness of the second air guiding part 132 are not changed, and the thickness of the first air guiding part 131 is gradually increased; alternatively, the thickness of the second air guiding portion 132 is not changed, and the distance between the surfaces of the first air guiding portion 131 and the second air guiding portion 132 that are close to each other and the thickness of the first air guiding portion 131 are gradually increased.
The airflow entering from the air inlet 150 has a certain component speed in the circumferential direction, so that the guide vane 130 guides the airflow and ensures the axial degree of the airflow after being blown out, the area of the guide vane 130 close to the air inlet 150 is bent, and the area of the guide vane 130 close to the air outlet 160 is straight and extends along the axial direction; thus, after the air flow enters the first air duct 140, the air flow is guided by the guide vane 130 at the air inlet side and gradually reduces the speed in the circumferential direction of the air flow, so that the air flow is gradually led out along the axial direction, and along with the continuous flow of the air flow, the air flow is finally guided by the guide vane 130 at the air outlet side, flows along the axial direction and is blown out from the air outlet 160.
Specifically, as shown in fig. 5, the first air guiding portion 131 includes a first bending section 1311 and a first axial flow section 1312 that are distributed along an axial direction of the first casing 110, the second air guiding portion 132 includes a second bending section 1321 and a second axial flow section 1322 that are distributed along an axial direction of the second casing 120, the first bending section 1311 and the second bending section 1321 are disposed near an air inlet side, the first axial flow section 1312 and the second axial flow section 1322 are disposed near an air outlet side, the first bending section 1311 and the second bending section 1321 are bent along a circumferential direction of the first casing 110 to weaken a circumferential velocity of an air flow and gradually guide the air flow along the axial direction, and an extending direction of the first axial flow section 1312 and the second axial flow section 1322 is parallel to the axial direction of the first casing 110 to ensure an axial degree of the air flow blown out from the air outlet 160.
Further, the first bending section 1311 and the second bending section 1321 are attached to each other in the circumferential direction of the first housing 110, and the first axial flow section 1312 and the second axial flow section 1322 are spaced apart from each other in the circumferential direction of the first housing 110. On the one hand, the wind guiding cavity 133 is closed towards one side of the air inlet 150, so that the air flow can be prevented from entering the wind guiding cavity 133 to form turbulence, on the other hand, the whole first bending section 1311 and the second bending section 1321 are mutually attached, the integral structural strength of the guide vane 130 can be improved, the vibration amplitude of the guide vane 130 is reduced, and the noise is reduced.
In one embodiment, the first wind guiding portion 131 is located on the windward side of the guide vane 130, the second wind guiding portion 132 is located on the leeward side of the guide vane 130, and the curvature of the connection between the first bending section 1311 and the first axial flow section 1312 is greater than the curvature of the connection between the second bending section 1321 and the second axial flow section 1322; therefore, the transition from the second bending section 1321 located on the leeward side to the second axial flow section 1322 is smoother, the airflow easily flows along the second bending section 1321 to the second axial flow section 1322, the leeward side of the guide vane 130 is not easy to generate an air compression area, and the flow loss of the airflow can be reduced.
It is conceivable that the guide vane 130, the first housing 110 and the second housing 120 are integrally connected, and the motor base 100 is integrally formed by injection molding or the like; or, the guide vane 130 is detachably connected with the first shell 110 and the guide vane 130 is detachably connected with the second shell 120, a groove body for the guide vane 130 to be inserted into or other concave-convex structures matched with the guide vane 130 are formed on the outer wall of the first shell 110 or the inner wall of the second shell 120, and the motor base 100 is formed by mutually assembling the first shell 110, the second shell 120 and the guide vane 130, so that the guide vane 130, the first shell 110 and the second shell 120 can be conveniently processed, and the processing cost of the motor base can be reduced.
Referring to fig. 6, an embodiment of the present invention further provides a motor, including the motor base 100 described above, the air guide cavity 133 extends along a radial direction of the first housing 110 and penetrates to an outer side of the second housing 120, so as to form an opening 121 at the outer side of the second housing 120, the motor further includes a stator 200 and a rotating shaft 300, the first housing 110 is annularly disposed outside the stator 200, the stator 200 is annularly disposed outside the rotating shaft 300, the stator 200 is connected with an outgoing line, the outgoing line passes through the air guide cavity 133 and the opening 121 and is led out from the opening 121, and after the outgoing line is connected with an external power source, the rotation of the rotating shaft 300 is powered.
In general, the lead wires of the windings in the stator 200 are led out from the axial end of the stator 200, and when the end of the stator 200 needs to be assembled in a matched manner with other components, the connection of the lead wires leads to complex assembly of the stator 200 and other components, and increases the assembly difficulty; in this embodiment, since the guide vane 130 has the air guiding cavity 133 inside, the lead-out wire can directly utilize the lead wire of the air guiding cavity 133 and lead out from the opening 121, so as to realize the lateral lead wire, and the defect of complex assembly of the stator 200 due to the lead-out of the motor lead-out wire is overcome on the premise of ensuring the wind pressure and wind speed of the air flow in the first air duct 140.
The radial direction, the axial direction, and the circumferential direction of the first casing 110, the second casing 120, the rotating shaft 300, the stator 200, and the guide vane 130 are the same, and the radial direction, the axial direction, and the circumferential direction may be referred to the first casing 110, the second casing 120, the rotating shaft 300, the stator 200, or the guide vane 130.
