DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0019] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. Where an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can also be present. The terms "vertical", "horizontal", "left", "right" and similar expressions as used herein are for illustration purposes only and are not intended to limit the embodiments of the present application.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0021] The application discloses a high-speed fan driving motor structure, as shown in the figure, comprising a shell 1 and a rotor structure 2, a stator structure 3 and an output shaft 4 arranged in the shell 1, the rotor structure 2 is arranged outside the stator structure 3 and fixedly connected with the output shaft 4; the rotor structure 2 comprises a barrel 21 and a plurality of rotor bodies one 22 arranged on the inner wall of the barrel 21, the stator structure 3 comprises a support cylinder 31 and a plurality of stator bodies 32 arranged on the support cylinder 31, the support cylinder 31 is coaxially arranged with the barrel 21 and located on the inner side of the barrel 21, and the output shaft 4 is coaxially arranged with the support cylinder 31 and fixedly connected with the barrel 21. Figures 1 to 5

[0022] ​In the application, the output shaft 4 is used for connecting with the external fan blades; the barrel body 21 is coaxial with the output shaft 4, and the opening of the barrel body 21 is towards the tail of the motor, the barrel body 21 bottom close to the front cover 11 is fixedly connected with the output shaft 4, so that the plurality of rotor bodies 22 on the barrel body 21 can be connected with the output shaft 4; the barrel body 21 and the output shaft 4 are combined into an annular space, the annular space is used for placing the stator structure 3, so as to form the structure form of the rotor wrapping the stator, and the opening position of the barrel body 21 can be used for providing the mounting space for the mutual connection between the stator structure 3 and the shell 1, so as to avoid that when the opening position of the barrel body 21 is directly blocked, the stator structure 3 is completely located inside the barrel body 21, and the structural disadvantage that the stator structure 3 cannot be effectively supported is caused.

[0023] In the specific implementation process, the motor is energized, the interaction force between the rotor body 22 and the stator body 32 around the circumferential direction of the output shaft 4 is generated, since the stator body 32 is connected with the rear cover 12 of the shell 1 through the support cylinder 31, the acting force of the stator body 32 on the rotor body 22 drives the barrel body 21 and the output shaft 4 to rotate, so that the motor is started and drives the external fan blades to rotate; since the plurality of rotor bodies 22 wrap the stator structure 3 inside, the position of the acting force received by the rotor body 22 is the position farthest from the axis of the output shaft 4 in the motor, so as to ensure that the torque provided by the rotor body 22 for the output shaft 4 is maximum, thereby increasing the output torque of the output shaft 4.

[0024] Compared with the stator and rotor structure 2 in the traditional motor, the position between the rotor structure 2 and the stator structure 3 is exchanged in the application, so that the rotor structure 2 is located outside the stator structure 3, thereby the rotor structure 2 is arranged to the position farthest from the output shaft 4 in the motor, so that under the condition that the stator structure 3 provides the constant acting force for the rotor structure 2, the rotor structure 2 can provide greater torque for the output shaft 4, thereby improving the output torque value of the motor; by using the structure of the barrel body 21, one end of the barrel body 21 can be connected with the output shaft 4, and the opening position of the other end of the barrel body 21 can be used for providing the mounting space for the connection between the stator structure 3 and the shell 1, so as to facilitate the shell 1 to provide support for the stator structure 3, and facilitate the assembly of the overall structure of the motor.

[0025] As a preferred embodiment of the above embodiment, the rotor body 22 and the rotor body 42 are arranged in the structure matched with the winding and the permanent magnet, or arranged in the structure matched with the two windings.

[0026] When the rotor body 22 is in the form of winding of wire, the stator body 32 can also be in the form of winding of wire or the permanent magnet structure, when the rotor body 22 is in the form of permanent magnet structure, the stator body 32 is in the form of winding of wire, so that the rotor body 22 and the stator body 32 can be used in cooperation, so as to facilitate the structure form that the rotor structure 2 wraps the stator structure 3 to be applicable to most motors, thereby improving the applicability.

[0027] Further, as shown in Figure 6 The winding structure of the rotor body one 22 is set up, and the winding axis is perpendicular to and intersects with the axis of the output shaft 4.

[0028] By setting the winding axis of the rotor body one 22, the direction of the magnetic field generated by the rotor body one 22 can be limited, so that the direction of the magnetic field generated by the rotor body one 22 towards the end face of the output shaft 4 can be along the radial direction of the output shaft 4, and the acting force between the rotor body one 22 and the stator body 32 can be along the circumferential tangent direction of the output shaft 4, thereby improving the effectiveness of force transmission and avoiding the situation that when the direction of the acting force is inclined, the acting force on the rotor body one 22 in the rotation direction of the output shaft 4 is small. The above-mentioned method only limits the direction of the magnetic induction lines close to the end face of the rotor body one 22, and does not limit the magnetic induction lines far from the end face of the rotor body one 22. When the rotor body one 22 and the stator body 32 move relative to each other, the stator body 32 and the end face of the rotor body one 22 approach each other.

[0029] In the embodiment, as shown in Figure 2 and Figure 6 The front cover 11 and the rear cover 12 are respectively arranged at both ends of the shell 1, and the two ends of the output shaft 4 pass through the front cover 11 and the rear cover 12 and are rotatably connected thereto. A sleeve 41 is arranged on the output shaft 4, and a plurality of rotor bodies two 42 are arranged on the sleeve 41 corresponding to the rotor body one 22. The output shaft 4 is fixedly connected to the bottom of the barrel body 21 through the sleeve 41, and the opening end of the barrel body 21 faces the rear cover 12.

[0030] The sleeve 41 is fixedly inserted into the middle part of the barrel body 21, and the output shaft 4 passes through the sleeve 41 and is connected together by means of bolts, clamps, welding or the like. The plurality of rotor bodies two 42 are distributed in the circumferential direction around the sleeve 41, and the winding direction of the rotor bodies two 42 is consistent with that of the rotor body one 22, so that the rotor bodies two 42 and the rotor body one 22 can be used together. That is, a stable magnetic field perpendicular to the output shaft 4 can be generated between the rotor body one 22 and the rotor bodies two 42, thereby achieving the combing of the magnetic induction lines and avoiding the scattering of the magnetic induction lines far from the end of the rotor body one 22, which leads to the disorder of the magnetic field.

[0031] The rotor body one 22 and the barrel body 21 cooperate with the sleeve 41 and the rotor bodies two 42 to form a structure similar to the traditional U-shaped magnet. The magnetic induction lines between the rotor body one 22 and the rotor bodies two 42 are the external magnetic induction lines of the magnet, and the part of the magnetic induction lines is perpendicular to the output shaft 4. The internal magnetic induction lines of the magnet are transmitted through the barrel body 21 and the sleeve 41, so that the magnetic field on the rotor structure 2 is more stable.

[0032] As a preferred embodiment of the above-mentioned embodiment, as shown in Figure 6As shown, a first magnetic uniform sleeve 23 is coaxially arranged inside the barrel 21 and is fixedly connected to the barrel 21 through multiple rotor bodies 22; a second magnetic uniform sleeve 43 is coaxially arranged outside the sleeve 41 and is fixedly connected to the sleeve 41 through multiple rotor bodies 42; and a support cylinder 31 is located between the first magnetic uniform sleeve 23 and the second magnetic uniform sleeve 43.

[0033] The magnetic forces on rotor body 22 and rotor body 42 are respectively transmitted to the first magnetic equalizing sleeve 23 and the second magnetic equalizing sleeve 43. This allows the magnetic field between the two magnetic equalizing sleeves to be evenly distributed in the circumferential direction of the output shaft 4, and the magnetic field lines to be along the radial direction of the output shaft 4. When the rotor structure 2 rotates to any angle, the magnitude of the force on the rotor structure 2 remains constant. This improves the uniformity of the force on the rotor structure 2 and ensures that the rotor structure 2 can be subjected to force in the circumferential direction of the output shaft 4. This improves the stability of the output torque of the output shaft 4 and avoids the disadvantage of unstable force on the rotor structure 2 when the stator body 32 is located between two adjacent rotor bodies 22 and when the stator body 32 is aligned with the rotor body 22.

[0034] In this embodiment, as Figure 4 As shown, in order to increase the interaction force between the rotor structure 2 and the stator structure 3, the arrangement of the stator body 32 is set. Specifically, multiple stator bodies 32 are arranged circumferentially along the support cylinder 31, and adjacent stator bodies 32 are respectively set on the outer wall and inner wall of the support cylinder 31.

[0035] By adopting the above-mentioned stator body 32 arrangement method, the support cylinder 31 is fully utilized, and the number of stator bodies 32 is increased. In some embodiments, since the magnetic field between the two uniform magnetic sleeves will pass through the support cylinder 31 and act on all the stator bodies 32, in order to avoid the support cylinder 31 from interfering with the magnetic field, the support cylinder 31 can be made of high-strength, non-metallic materials, such as carbon fiber composite materials.

[0036] In this embodiment, as Figures 5 to 7 As shown, a support ring 14 is provided on the inner wall of the housing 1 corresponding to the barrel 21. A rolling element 141 is provided on the inner side of the support ring 14. The rolling element 141 is rotatably connected to the support ring 14 and multiple of them are provided in the circumference. A ring groove 215 is provided on the outer wall of the barrel 21 corresponding to the support ring 14. Multiple support rings 14 and ring grooves 215 are provided. The barrel 21 is rotatably connected to the support ring 14 through the rolling element 141.

[0037] Multiple support rings 14 and multiple ring grooves 215 are used in conjunction with each other. The rolling element 141 slides on the bottom of the ring groove 215, so that the barrel 21 can rotate with low friction on the multiple support rings 14, and the position of the barrel 21 is restricted.

[0038] As a preferred embodiment of the above, such as Figures 4 to 5 As shown, the support cylinder 31 is rotatably connected to the rear cover 12 via a transmission ring 311 at its end. A transmission wheel 121 is provided on the rear cover 12 corresponding to the transmission ring 311. A rotating wheel 44 is sleeved on the output shaft 4. The rotating wheel 44 drives the transmission ring 311 to rotate via the transmission wheel 121. Multiple transmission wheels 121 are provided around the circumference of the transmission ring 311.

[0039] When the stator structure 3 provides force to the rotor structure 2 and drives the rotor structure 2 to rotate, the stator structure 3 is also subjected to a reaction force. If the stator structure 3 is fixedly connected to the housing 1, the reaction force of the stator structure 3 will be transmitted to the housing 1, and the force will not be effectively utilized. To solve this problem, the above-mentioned structural method can be used, that is, the reaction force of the rotor structure 2 on the stator structure 3 will drive the stator structure 3 to rotate. The stator structure 3 transmits the force to the output shaft 4 through the support cylinder 31, the transmission ring 311 and the transmission wheel 121, thereby enabling both the rotor structure 2 and the stator structure 3 to drive the output shaft 4.

[0040] In this embodiment, as Figures 3 to 6 As shown, a first annular cavity 51 is formed between the support cylinder 31 and the sleeve 41, and a second annular cavity 52 is formed between the barrel 21 and the support cylinder 31. The first annular cavity 51 and the second annular cavity 52 are connected and form a flow channel with a U-shaped cross section. An air intake channel 45 is provided along its axial direction at one end of the output shaft 4 that extends out of the front cover 11, and a vent hole 46 is provided on the side wall of the output shaft 4. The air intake channel 45 is connected to the first annular cavity 51 through the vent hole 46. Multiple air guide ports 122 are provided circumferentially on the rear cover 12 located on the outer ring of the support cylinder 31. The air guide ports 122 are connected to the second annular cavity 52. ​​Multiple tail blades 47 are provided circumferentially at one end of the output shaft 4 that extends out of the rear cover 12. A tail cover 13 is provided on the housing 1 corresponding to the tail blades 47, and multiple mesh holes 131 are provided on the tail cover 13.

[0041] Secondly, a plurality of first fan plates 231 are arranged in a spiral direction on the inner wall of the first magnetic equalizing sleeve 23, and a plurality of second fan plates 431 are arranged in a spiral direction on the outer wall of the second magnetic equalizing sleeve 43. The spiral directions of the plurality of first fan plates 231 and the plurality of second fan plates 431 are opposite. An mounting sleeve 48 is provided in the air intake channel 45, and a spiral blade 481 is provided in the mounting sleeve 48.

[0042] Since the support cylinder 31 is located between the two magnetic equalizing sleeves, a transverse channel, namely the first annular cavity 51, can be formed between the support cylinder 31 and its first magnetic equalizing sleeve 23; a vertical channel is formed between the end of the support cylinder 31 and the bottom of the barrel 21, and another transverse channel, namely the second annular cavity 52, is formed between the support cylinder 31 and its outer second magnetic equalizing sleeve 43; the two transverse channels are connected by a vertical channel. For example, taking the cross-sectional structure on one side of the output shaft 4 as an example, a horizontally opening U-shaped channel is formed between the two magnetic equalizing sleeves and the support cylinder 31. One end of this U-shaped channel is connected to the vent 46, and the other end is connected to the air guide port 122; during rotation... When substructure 2 rotates, multiple fan blades on the two magnetic sleeves rotate synchronously. The multiple fan blades push the air between rotor structure 2 and stator structure 3 along the U-shaped channel trajectory. A low-pressure area is formed near the vent 46 due to the reduction of air. This low-pressure area will draw in air from the external fan through the vent 46 and the air intake channel 45. The drawn-in air is then guided into the tail cover 13 through the U-shaped channel and the air guide port 122. The rotating output shaft 4 and its multiple tail blades 47 push the air in the tail cover 13 out through the mesh 131, thereby forming a stable air path inside the motor, which facilitates continuous cooling of the motor interior using air.

[0043] Furthermore, when the output shaft 4 rotates, the mounting sleeve 48 and the spiral blade 481 inside the output shaft 4 will rotate synchronously. The spiral blade 481 will assist in pushing air through the intake channel 45 into the housing 1, thereby increasing the cooling effect.

[0044] In some embodiments, the air discharged through the mesh 131, due to its pressure, can also be used as the output airflow of the fan.

[0045] In this embodiment, see Figure 8 As shown, a sealing plate 211 is provided at one end of the barrel 21 near the rear cover 12, corresponding to the air inlet 122. The sealing plate 211 is connected to the guide seat 213 on the barrel 21 through an elastic body 212. The guide seat 213 is arranged radially along the barrel 21 and inclined toward the rear cover 12. The sealing plate 211 slides obliquely along the guide seat 213 through a slider 214 on it. The slider 214 is set as a wedge structure corresponding to the guide seat 213.

[0046] When the rotor structure 2 rotates, the barrel 21 will drive the sealing plate 211, slider 214 and guide seat 213 to rotate synchronously. Due to the centrifugal force, the sealing plate 211 and slider 214 will move away from the output shaft 4. Since the slider 214 and guide seat 213 slide relative to each other, the sealing plate 211 will also move away from the air inlet 122. At this time, the sealing plate 211 stops blocking the air inlet 122. That is, when the motor is running, the sealing plate 211 will automatically open. When the motor stops running, the elastic body 212 can be used to make the sealing plate 211 automatically close the air inlet 122, thereby preventing external impurities from entering the motor.
