Description

[0002] A brushless DC motor (BLDC: Brushless Direct Current Motor), also known as an electronically commutated motor (ECM or EC motor) or a synchronous DC motor, is a synchronous motor that uses a direct current (DC) power supply.

[0026] 4. By adopting the brushless DC (BLDC) method in the in-wheel motor, the efficiency is higher, the energy consumption is lower, and rubber shock-absorbing sleeves are added to both shaft sleeves. At the same time, the motor is brushless DC with variable frequency and speed regulation, so as to control the wind speed, reduce the generated noise and achieve low energy consumption.

[0042] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination can be formed among the following-described embodiments or technical features to form new embodiments. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0043] Please refer to Figures 1 to 14 , the present invention provides a technical solution: as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, it includes a driving mechanism 2, and this driving mechanism 2 is composed of a hub motor assembly;

[0044] A wind power mechanism 4, and this wind power mechanism 4 is used for wind power transmission processing inside the equipment;

[0045] A housing 1 is fixedly installed on the outside of the wind power mechanism 4, the driving mechanism 2 is arranged inside the housing 1, and a filter screen 3 is fixedly connected to the outside of the housing 1.

[0046] Among them, the driving mechanism 2 includes a blowing housing 21. One side of the blowing housing 21 close to the filter screen 3 is fixedly connected with a partition plate 22. The bottom of the blowing housing 21 is fixedly installed with a base 23, and the base 23 is fixedly installed at the bottom of the inner cavity of the housing 1. One end of the blowing housing 21 far from the partition plate 22 is fitted with a flow blocking disc 24. A stator assembly 25 is arranged inside the blowing housing 21. A support plate 26 is installed at the central part of the inner cavity of the stator assembly 25. A rotor assembly 27 is installed inside the support plate 26. One end of the rotor assembly 27 is connected with a connecting piece 28, and one end of the connecting piece 28 far from the rotor assembly 27 is connected with a circuit 29. In addition, the in-wheel motor adopts a DC brushless method, BLDC, with higher efficiency and lower energy consumption. Rubber shock-absorbing sleeves are added to both shaft sleeves, and at the same time, the motor is DC brushless and frequency-converted with speed regulation.

[0047] The outer side of the connecting piece 28 is rotatably connected with a second shaft sleeve 209. The outer side of the second shaft sleeve 209 is fixedly connected with a first hub body 20. One end of the first hub body 20 far from the second shaft sleeve 209 is fixedly connected with a first end face plate 201, and the first end face plate 201 is fixedly connected to the outer side of the blowing housing 21. One end of the rotor assembly 27 far from the connecting piece 28 is connected with a driving shaft 202. One end of the driving shaft 202 far from the rotor assembly 27 is fixedly connected with a compensating shaft 203. One end of the compensating shaft 203 far from the driving shaft 202 is connected with a coupling 204. One end of the coupling 204 far from the compensating shaft 203 is connected with a first fan 205. The outer side of the driving shaft 202 is rotationally fitted with a first shaft sleeve 208. The outer side of the first shaft sleeve 208 is fixedly connected with a second hub body 206. One end of the second hub body 206 far from the first shaft sleeve 208 is fixedly connected with a second end face plate 207, and the second end face plate 207 is fixedly connected to the outer side of the partition plate 22. By energizing the circuit 29, then the rotor assembly 27 will rotate forward in the stator assembly 25. Among them, the driving shaft 202 connected to the stator assembly 25 will drive the compensating shaft 203 to rotate forward, and the other end of the compensating shaft 203 is connected with the first fan 205 through the coupling 204. Therefore, the first fan 205 will rotate forward, and the wind towards the filter screen 3 will be sucked into the blowing housing 21, and then discharged from the air outlet of the blowing housing 21, so as to achieve the purpose of air intake and air outlet.

[0048] Such as Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, the wind power mechanism 4 includes a first traction plate 40 and a second traction plate 401. Both the first traction plate 40 and the second traction plate 401 are fixedly connected to the inner side of the housing 1. A support rod 41 is arranged between the first traction plate 40 and the second traction plate 401. One end of the support rod 41 is fixedly connected to the outer side of the blowing housing 21. The end of the support rod 41 away from the blowing housing 21 is fixedly connected with a servo motor 42. The outer side of the output end of the servo motor 42 is fixedly connected with a quadrilateral plate 43. A wind power component 44 is arranged beside the quadrilateral plate 43. The wind power component 44 is fixedly installed on the inner side of the housing 1. The outer end of the output end of the servo motor 42 is connected with a second fan 45. The outer side of the housing 1 is fixedly connected with an inclined rod 46. The end of the inclined rod 46 away from the housing 1 is fixedly connected with a limiting ring 47. An elastic filter screen 48 is slidably fitted on the outer side of the inclined rod 46. One side of the elastic filter screen 48 away from the limiting ring 47 is fixedly connected with an elastic ring piece 49. A slit is formed at the bottom of the elastic ring piece 49. As the threaded hollow rod 442 spirally moves inward, the extension rod 441 connected to the other end no longer presses the elastic filter screen 48, but moves toward the housing 1 together with the threaded hollow rod 442. The elastic ring piece 49 connected to the inner side of the elastic filter screen 48, under the elastic force of its compression, makes the elastic filter screen 48 move along the inclined rod 46 and toward the housing 1. At this time, the diameter of the holes on the surface of the elastic filter screen 48 will shrink, so as to play a role in filtering impurities in the wind blown by the second fan 45. When the elastic ring piece 49 is in the extended state, the diameter of the holes on the surface of the elastic filter screen 48 will become larger, which is convenient for the operator to clean the impurities at the holes.

[0049] In addition, a slit is formed at the bottom of the elastic ring piece 49, which is convenient for discharging impurities downward.

[0050] The wind power assembly 44 includes an extension rod 441. One end of the extension rod 441 is in pressing fit with the inner side of the elastic filter screen 48. The end of the extension rod 441 away from the elastic filter screen 48 is fixedly connected with a threaded hollow rod 442. The threaded hollow rod 442 is threadedly connected to the outer side of the housing 1. A tapered head 443 is slidably fitted inside the threaded hollow rod 442. The end of the tapered head 443 away from the threaded hollow rod 442 is fixedly connected to a connecting plate 444. The connecting plate 444 is fixedly connected to the inner side of the housing 1. The outer side of the tapered head 443 is in pressing fit with a bottom curved block 445. The bottom curved block 445 penetrates through the outer side of the threaded hollow rod 442 and extends into its interior. Both ends of the bottom curved block 445 are symmetrically connected with side plates 446. The bottom of the side plate 446 is fixedly connected with a return spring 447. The bottom end of the return spring 447 is fixedly connected to the outer side of the threaded hollow rod 442. Immediately afterwards, start the servo motor 42, and the second fan 45 connected to its output end will rotate, thereby sucking the wind on the other side of the housing 1 into its interior. In addition, as the output end of the servo motor 42 rotates, the quadrilateral plate 43 fixedly connected to its outer side will rotate forward and strike the bottom curved block 445. The struck bottom curved block 445 will give a driving force to the threaded hollow rod 442. Since the bottom curved block 445 penetrates through the threaded hollow rod 442, the threaded hollow rod 442 will rotate spirally inward along the surface of the housing 1. Therefore, the bottom curved block 445 inserted inside the threaded hollow rod 442 will rotate inward accordingly. However, one end of the bottom curved block 445 inside the threaded hollow rod 442 is in pressing fit with the tapered head 443. The contact surfaces between the bottom curved block 445 and the tapered head 443 are both curved surfaces, and the tapered head 443 is fixed through the connecting plate 444. Therefore, as the bottom curved block 445 spirally moves towards the tapered head 443 and under the compression force of the return spring 447, the original shape of the return spring 447 is in a compressed state, and it plays a role in resetting the bottom curved block 445, making the bottom curved block 445 gradually extend into the threaded hollow rod 442. At this time, the part of the bottom curved block 445 extending out of the threaded hollow rod 442 will gradually shorten until the quadrilateral plate 43 can no longer squeeze it. At this time, the threaded hollow rod 442 and the bottom curved block 445 will no longer continue to rotate, thus playing a role in the preliminary treatment of subsequent filtration.

[0051] As Figure 11 , Figure 12 , Figure 13 and Figure 14 shown, the water cooling mechanism 5 is used for water cooling and heat dissipation treatment of the hub motor assembly;

[0052] The water cooling mechanism 5 is fixedly installed inside the housing 1;

[0053] Among them, the water cooling mechanism 5 includes an outlet pipe 51. The outlet pipe 51 is sleeved outside the housing 1. The inner end of the outlet pipe 51 is fixedly connected with a through pipe 52. The through pipe 52 penetrates through the bottom of the housing 1. A wet curtain 53 is fixedly connected inside the through pipe 52. A transition plate 54 is arranged directly above the wet curtain 53. The transition plate 54 is fixedly installed at the top of the through pipe 52. The top of the transition plate 54 is fixedly connected with a double-connected pipe 55. A porous pipe 56 is inserted into the top of the double-connected pipe 55. The bottom end of the porous pipe 56 is inserted into a water tank 57. The water tank 57 is fixedly installed at the bottom of the housing 1. Among them, the porous pipe 56 and the water tank 57 are connected by a water pump. At the same time, the top of the water tank 57 is interconnected with the through pipe 52. The wind drawn in by the second fan 45 will blow into the through pipe 52 along the first traction plate 40 and the second traction plate 401 respectively. And a plurality of wet curtains 53 are fixedly connected inside the through pipe 52. Then, start the water pump inside the water tank 57, so that the water pump will pump the water inside the water tank 57 into the porous pipe 56. Among them, the bottom of the porous pipe 56 is connected with a plurality of double-connected pipes 55, and the bottom of each double-connected pipe 55 is fixedly connected with a transition plate 54. And directly below each transition plate 54 is the wet curtain 53. Therefore, water is sprinkled on the wet curtain 53, and the wind blows through the wet curtain 53, so that the temperature of the wind will be greatly reduced and it will carry a little moisture. At this time, the flowing wind not only plays a role in dissipating heat from the hub motor assembly inside the blowing shell 21, but also plays a role in humidifying and cooling the wind blown out by the hub motor assembly.

[0054] When the present invention is in use: First, the circuit 29 is powered on. Subsequently, the rotor assembly 27 will rotate forward within the stator assembly 25. Among them, the drive shaft 202 connected to the stator assembly 25 will drive the compensation shaft 203 to rotate forward. The other end of the compensation shaft 203 is connected to the first fan 205 through a coupling 204. Therefore, the first fan 205 will rotate forward and suck the wind towards the filter screen 3 into the blowing shell 21, and then discharge it from the air outlet of the blowing shell 21, so as to achieve the purpose of air intake and air outlet. Immediately afterwards, the servo motor 42 is started, so that the second fan 45 connected to its output end will rotate, thereby realizing sucking the wind on the other side of the housing 1 into its interior. In addition, as the output end of the servo motor 42 rotates, the quadrilateral plate 43 fixedly connected to its outer side will rotate forward and hit the bottom curved block 445. The hit bottom curved block 445 will drive the threaded hollow rod 442 to rotate forward. The bottom curved block 445 is inserted into the threaded hollow rod 442, causing the threaded hollow rod 442 to rotate spirally inward along the surface of the housing 1. Therefore, the bottom curved block 445 inserted into the threaded hollow rod 442 will rotate spirally inward accordingly. However, one end of the bottom curved block 445 inside the threaded hollow rod 442 is in pressing fit with the conical head 443, and the conical head 443 is fixed. Therefore, as the bottom curved block 445 moves spirally towards the conical head 443 and under the compression force of the return spring 447, the bottom curved block 445 will gradually extend into the threaded hollow rod 442. At this time, the part of the bottom curved block 445 extending out of the threaded hollow rod 442 will gradually shorten until the quadrilateral plate 43 can no longer press it. At this time, the threaded hollow rod 442 and the bottom curved block 445 will no longer rotate. At the same time, the extension rod 441 connected to the other end of the threaded hollow rod 442 will no longer press the elastic filter screen 48, but move towards the housing 1 together with the threaded hollow rod 442. Finally, under the elastic force of the elastic ring 49, the elastic filter screen 48 will move along the inclined rod 46 and towards the housing 1. At this time, the diameter of the holes on the surface of the elastic filter screen 48 will shrink to achieve the subsequent function of filtering impurities in the wind.

[0055] The wind drawn in by the second fan 45 will blow into the middle through pipe 52 along the first guiding plate 40 and the second guiding plate 401 respectively. A number of wet curtains 53 are fixedly connected inside the middle through pipe 52. Then, start the water pump inside the water tank 57, so that the water pump will pump the water inside the water tank 57 into the porous pipe 56. The bottom of the porous pipe 56 is connected with a number of double-connection pipes 55, and the bottom of each double-connection pipe 55 is fixedly connected with a transition plate 54. Below each transition plate 54 is directly opposite to the wet curtain 53. Therefore, water is sprinkled on the wet curtain 53, and the wind blows through the wet curtain 53, so that the temperature of the wind will be greatly reduced and it will carry a little moisture. At this time, the flowing wind will not only dissipate heat from the hub motor assembly inside the blowing shell 21, but also humidify and cool the wind blown out by the hub motor assembly.

[0056] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Those of ordinary skill in the art, starting from the above concepts and without creative labor, make various changes, which all fall within the scope of protection of the present invention.
