Description

Technical Field

[0001] This invention relates to the field of micro motor technology, specifically to a high-efficiency heat dissipation micro motor. Background Technology

[0002] Miniature motors are a type of motor with small size and capacity, and output power generally below several hundred watts. They are a type of motor with special requirements for application, performance, and environmental conditions.

[0003] A micro motor with good heat dissipation, as described in application number CN202210213116.8, includes a base, an adjustment and fixing mechanism, a shock-absorbing support mechanism, a heat dissipation mechanism, a linkage mechanism, and a cleaning mechanism. The adjustment and fixing mechanism is located on both sides of the inner wall of the base. A shock-absorbing support mechanism is fixedly installed on the top of the shock-absorbing support mechanism, and a motor is fixedly installed on the inner side of the shock-absorbing support mechanism. A bottom opening and closing mechanism is provided on one side of the motor, and the heat dissipation mechanism is fixedly installed on the inner side of the base. In this invention, by providing a bottom opening and closing mechanism, a heat dissipation mechanism, and a linkage mechanism, the heat dissipation mesh is pushed so that the heat dissipation mesh drives the movable hook to contact the two sides of the movable block. Continuous pushing causes the two sides of the movable hook to fold inward until they pass through the movable block, and then the movable hook springs back, thereby connecting and fixing the movable block and the movable hook. This allows the heat dissipation mesh to be fixedly installed on one side of the bottom of the motor, which can more conveniently dissipate the high temperature inside the motor and avoid damage to the motor caused by prolonged high temperature.

[0004] The aforementioned existing patents use a combination of foldable heat dissipation mesh and cooling fan to assist in heat dissipation inside the micro motor. However, since the rotor inside the micro motor is running at high speed, it will be in a state of heat for a long time. Simply using the cooling fan to expel the hot air is not very efficient in helping to dissipate heat inside the micro motor, resulting in low heat dissipation efficiency. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention incorporates a heat dissipation device at the rear of the motor body. When the rotor body operates within the motor body, it drives a first fan connected to the outer end, causing the fan to rotate and aiding in the expulsion of heat from within the motor body. Simultaneously, the rotation of the rotor body enables the meshing transmission of a first bevel gear and a second bevel gear. This, in conjunction with the rotating shaft, allows the bottom-mounted air intake assembly to operate, enabling external air to quickly enter the air supply assembly and then the motor body, enhancing airflow within the motor body. Furthermore, the cooling assembly located outside the air supply assembly cools the incoming air, further enhancing the internal heat dissipation of the motor. Additionally, the rotating shaft's rotation activates an extension assembly to provide omnidirectional airflow, further strengthening the airflow within the heat dissipation area.

[0018] The connection between the housing, filter, first fan, first bevel gear, second bevel gear, and rotating shaft allows the externally connected first fan to rotate when the rotor is rotating, thus dissipating heat from the motor body. Simultaneously, the rotating rotor also enables the meshing transmission of the first and second bevel gears, thereby facilitating the coordinated rotation of the rotating shaft and driving the components connected at the bottom, improving the ease of use of the structure.

[0019] The air intake assembly is designed so that when the shaft rotates, the meshing transmission of the third and fourth bevel gears can be achieved. This drives the rotating rod connected in the middle of the fourth bevel gear, allowing the rotating rod to rotate stably with the support of the connecting plates on the front and rear sides. As a result, the scrapers and the second fan located at both ends of the rotating rod will rotate simultaneously to assist in scraping and cleaning the dust adhering to the outside of the air supply assembly, avoiding air intake blockage problems, and enabling the rapid intake of external air. This allows external air to quickly enter the motor body, improving the air circulation effect inside the motor body and meeting the requirements of efficient heat dissipation.

[0020] The air supply and cooling components are designed so that when external air enters the conveying pipe for heat dissipation, the heat dissipation fins installed on both sides of the conveying pipe absorb and cool the incoming air, thereby reducing the temperature of the air entering the motor body and improving its heat dissipation effect. At the same time, the coolant stored in the liquid tank can be circulated through the circulation structure to further aid in the heat absorption and cooling of the air and the heat dissipation fins, thus helping to strengthen and maintain the stable cooling effect of the air and the cooling effect of the heat dissipation fins.

[0021] The expansion component is designed so that when the shaft rotates, it can simultaneously drive the externally connected drive wheel. The drive wheel, in conjunction with an external belt, drives the driven wheel on the other side. As the driven wheel rotates, the rotating arm connected to the upper end of the driven wheel rotates accordingly. Through the gear set at the upper end, it drives the rotating connecting cylinder inside the connecting frame, allowing the connecting cylinder to rotate in conjunction with the connecting frame and the bracket, thus enabling omnidirectional rotation. Simultaneously, the fan blades connected to the gear set and connected to the middle of the upper end of the connecting cylinder rotate synchronously with the rotation of the connecting cylinder, enabling omnidirectional air blowing to increase the air intake range and enhance the heat dissipation effect inside the motor body.

Detailed Implementation

[0033] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0034] Please see Figure 1The present invention provides a high-efficiency heat dissipation micro motor, including a motor body 1, a rotor body 2, support legs 3 and a heat dissipation device 4. The rotor body 2 is installed inside the motor body 1. Support legs 3 are bolted to both sides of the motor body 1. The heat dissipation device 4 is connected to the side of the rotor body 2 away from the output end, and the heat dissipation device 4 is connected to the lower end of the motor body 1.

[0035] Please see Figure 2-3 In this embodiment, the heat dissipation device 4 includes a connecting shell 41, a filter 42, a first fan 43, a first bevel gear 44, a second bevel gear 45, a rotating shaft 46, an air inlet assembly 47, an air delivery assembly 48, a cooling assembly 49, and an expansion assembly 410. The connecting shell 41 is installed on the rear side of the motor body 1, and the filter 42 is installed on the side of the connecting shell 41 away from the motor body 1 to achieve dust prevention and blocking of movement. The first fan 43 is provided inside the connecting shell 41, and the middle part of the first fan 43 is connected to the rotor body 2, so that the first fan 43 can rotate synchronously with the rotor body 2 to achieve the rotation and exhaust of hot air. The first bevel gear 44 is installed on the filter 42. In the middle, the first bevel gear 44 is connected to the rotor body 2. Thus, when the rotor body 2 rotates, the first bevel gear 44 can be rotated synchronously. The lower end of the first bevel gear 44 is meshed with the second bevel gear 45, and the lower end of the second bevel gear 45 is connected to the rotating shaft 46. The lower end of the rotating shaft 46 is connected to the air inlet assembly 47 and the air delivery assembly 48. The air inlet assembly 47 is installed inside the air delivery assembly 48. The air outlet of the air delivery assembly 48 is connected to the lower end of the motor body 1. A cooling assembly 49 is installed on the outside of the air delivery assembly 48. An extension assembly 410 is installed inside the air outlet of the air delivery assembly 48, and one side of the extension assembly 410 is connected to the rotating shaft 46.

[0036] Specifically, when the rotor body 2 inside the motor body 1 is in a rotating drive state, it can realize the rotation drive of the first fan 43 connected to one side. As the first fan 43 rotates, it will help to exhaust the heat generated inside the motor body 1, thereby realizing the heat dissipation of the motor body 1 and avoiding the problem of excessive internal temperature. At the same time, when the rotor body 2 rotates, it can also realize the rotation of the first bevel gear 44 connected to the outer end, so that the first bevel gear 44 can realize the meshing transmission of the second bevel gear 45 at the bottom. In this way, the rotating shaft 46 connected to the lower end of the second bevel gear 45 can realize the linkage drive of the air intake component 47 connected to the lower end.

[0037] Please see Figure 4In this embodiment, the air intake assembly 47 includes a third bevel gear 471, a fourth bevel gear 472, a rotating rod 473, a connecting plate 474, a scraper 475, and a second fan 476. The third bevel gear 471 is connected to the lower end of the rotating shaft 46, and the lower end of the third bevel gear 471 is meshed with the fourth bevel gear 472. Both the third bevel gear 471 and the fourth bevel gear 472 are located inside the air supply assembly 48. The rotating rod 473 is longitudinally connected to the middle of the fourth bevel gear 472, and both the front and rear sides of the rotating rod 473 are connected to the interior of the connecting plate 474. The front and rear connecting plates 474 are fixedly connected to the interior of the air supply assembly 48. In this way, the rotating rod 473 can be stably supported longitudinally. The scraper 475 is bolted to the outer end of the rotating rod 473, and two second fans 476 are installed on the inner and outer sides of the rotating rod 473. With the rotation assistance of the two second fans 476, the external air can be quickly introduced for circulation and heat dissipation.

[0038] The first bevel gear 44 and the second bevel gear 45, and the third bevel gear 471 and the fourth bevel gear 472 are symmetrically arranged vertically. The shaft 46 between the second bevel gear 45 and the third bevel gear 471 is vertically rotated and inserted into the conveying pipe 481 to ensure stable linkage and transmission between the first bevel gear 44 and the second bevel gear 45, and between the third bevel gear 471 and the fourth bevel gear 472.

[0039] Specifically, when the rotating shaft 46 rotates due to the meshing transmission of the first bevel gear 44 and the second bevel gear 45, the third bevel gear 471 connected to the lower end of the rotating shaft 46 can rotate and mesh with the fourth bevel gear 472 connected to the bottom. Thus, the rotating rod 473 connected to the middle of the fourth bevel gear 472 will cooperate with the support of the connecting plates 474 connected to the front and rear sides to perform stable rotational activities. As a result, the two second fans 476 installed at the rear outer end of the rotating rod 473 will rotate simultaneously to realize the intake of external air, so that the external air enters the air supply assembly 48 and then enters the motor body 1 along the air supply assembly 48 to realize air circulation and enhance the heat dissipation effect inside the motor body 1.

[0040] Please see Figure 5 In this embodiment, the air supply assembly 48 includes a delivery pipe 481, a dust cover 482, and a connecting pipe 483. The top of the air inlet end of the delivery pipe 481 is bolted to the lower end of the connecting shell 41 via a plate. The air inlet end of the delivery pipe 481 is provided with a dust cover 482, and the outside of the dust cover 482 abuts against the scraper 475. Thus, the scraper 475 can rotate to assist in cleaning the outside of the dust cover 482. The air outlet end of the delivery pipe 481 is fixedly provided with a connecting pipe 483, and the connecting pipe 483 is bolted to the lower end of the motor body 1.

[0041] Specifically, the air drawn in by the rotation of the second fan 476 can pass through the dust cover 482 connected to the air inlet of the conveying pipe 481 to achieve filtration and prevent dust in the air from entering. The air that enters the conveying pipe 481 can enter the motor body 1 through the connecting pipe 483 connected to the upper rear side of the conveying pipe 481 to assist in the air circulation inside the motor body 1, so that the circulating air can quickly carry away the heat generated by the operation of the motor body 1 and further enhance the heat dissipation effect of the motor body 1.

[0042] Secondly, when the dust cover 482 is used for dust filtration for a long time, a certain amount of dust will adhere to its exterior, resulting in a reduction in air intake efficiency. At this time, the scraper 475, which is connected to the outside of the rotating rod 473 and abuts against the exterior of the dust cover 482, will rotate synchronously when the rotating rod 473 rotates to suck air, so as to scrape off the dust and impurities adhering to the exterior of the dust cover 482, ensuring the cleanliness of the exterior of the dust cover 482 and reducing the problem of dust adhesion affecting air intake efficiency.

[0043] Please see Figure 6-7 In this embodiment, the cooling component 49 includes a liquid storage tank 491, a circulation structure 492, and heat dissipation fins 493. The liquid storage tank 491 is installed on the upper end of the delivery pipe 481, and the circulation structure 492 is connected to the outside of the liquid storage tank 491. The heat dissipation fins 493 are installed on both sides of the outer end of the delivery pipe 481, and the outer side of the heat dissipation fins 493 is in contact with the circulation structure 492. By installing the heat dissipation fins 493, the air transmitted inside the delivery pipe 481 can absorb heat and cool down, thereby improving the subsequent heat dissipation effect.

[0044] The storage tank 491 is equipped with a pump body (not shown directly in this application), and the water outlet of the pump body is connected to the circulation structure 492. The pump body is consistent with the water pump in the prior art, so its specific structure will not be described in detail.

[0045] The circulation structure 492 includes an outlet pipe 4921, a first circulation pipe 4922, a first connecting pipe 4923, a transmission pipe 4924, a second connecting pipe 4925, a second circulation pipe 4926, and an inlet pipe 4927. The outlet pipe 4921 is connected to the outlet end of the storage tank 491, and the side of the outlet pipe 4921 away from the storage tank 491 is connected to the first circulation pipe 4922. The upper middle part of the first circulation pipe 4922 is vertically connected to the first connecting pipe 4923, and the first connecting pipe 4923 is... The end is connected to the transmission pipe 4924, and the transmission pipe 4924 is inserted into the rear side of the outlet pipe 4921 but not connected. The side of the transmission pipe 4924 away from the first connector 4923 is connected to the second connector 4925, and the lower end of the second connector 4925 is connected to the second circulation pipe 4926. The upper middle part of the second circulation pipe 4926 is connected to the inlet pipe 4927, and the inlet pipe 4927 is connected to the inlet end of the liquid storage tank 491. The lower front side of the inlet pipe 4927 is inserted into but not connected to the outlet pipe 4921.

[0046] The first circulation pipe 4922 and the second circulation pipe 4926 are both wrapped around the outside of the delivery pipe 481. At the same time, the outside of the first circulation pipe 4922 and the second circulation pipe 4926 also moves into the interior of the heat dissipation fins 493. In this way, with the circulation and transmission of the cooling liquid inside the first circulation pipe 4922 and the second circulation pipe 4926, the incoming air can be cooled down and the heat dissipation fins 493 can be cooled down by contact, thereby improving the heat dissipation efficiency of the heat dissipation fins 493.

[0047] The heat dissipation fins 493 are arranged in pairs on the left and right sides of the outer end of the conveying pipe 481, and the outer sides of the heat dissipation fins 493 on both sides are in contact with the outer sides of the first circulation pipe 4922 and the second circulation pipe 4926, so as to ensure that the heat dissipation fins 493 can achieve efficient heat absorption and cooling of the air entering the conveying pipe 481.

[0048] Specifically, when air enters the inside of the conveying pipe 481 and enters the inside of the motor body 1 with the help of wind, it will absorb heat and cool down through the heat dissipation fins 493 provided on the left and right sides of the conveying pipe 481. This will lower the temperature of the incoming air and ensure that the air entering the motor body 1 can not only carry away heat, but also improve the stability of the electronic components inside the motor body 1 in a stable state in conjunction with the temperature reduction activity.

[0049] Simultaneously, by operating the pump inside the liquid storage tank 491, the pump can transfer the cooling liquid inside the liquid storage tank 491 to the outlet pipe 4921. In this way, through the transmission and cooperation of the first circulation pipe 4922, the first connecting pipe 4923, the transmission pipe 4924, the second connecting pipe 4925, the second circulation pipe 4926 and the inlet pipe 4927, it can be reintroduced into the liquid storage tank 491, thus completing one water cooling cycle. In this way, when the cooling liquid is circulated and transferred to the transmission pipe 4924, the cooling of the air entering can be improved, thereby further reducing air problems. Secondly, when the circulating cooling liquid flows into the first circulation pipe 4922 and the second circulation pipe 4926, it will absorb heat from the externally abutting heat dissipation fins 493, so that the heat dissipation fins 493 can accelerate the heat dissipation and ensure that they are in a state of efficient air heat absorption. This makes the air entering the delivery pipe 481 absorb heat and cool down stably, thereby enhancing the subsequent heat dissipation and cooling effect on the motor body 1.

[0050] Please see Figure 8-10 In this embodiment, the expansion component 410 includes a drive wheel 4101, a belt 4102, a driven wheel 4103, a bracket 4104, a rotating arm 4105, a gear set 4106, a connecting cylinder 4107, a connecting frame 4108, and a fan blade 4109. The drive wheel 4101 is connected to the outside of the rotating shaft 46, and the belt 4102 is externally connected to the drive wheel 4101. The side of the belt 4102 away from the drive wheel 4101 is connected to the driven wheel 4103. The driven wheel 4103 is rotatably mounted in the middle of the bracket 4104, and the bracket 4104 is fixedly connected to the inside of the connecting tube 483. The upper end of 03 is connected to the rotating arm 4105, and the upper end of the rotating arm 4105 is connected to the gear set 4106. Thus, as the rotating arm 4105 rotates with the driven wheel 4103, it can drive the gear set 4106 in a coordinated manner. The gear set 4106 is installed at the bottom of the connecting cylinder 4107, and the front and rear sides of the connecting cylinder 4107 are rotatably connected to the front and rear sides inside the connecting frame 4108. The left and right sides of the connecting frame 4108 are rotatably connected to the left and right sides of the upper end of the bracket 4104, respectively. A fan blade 4109 is rotatably installed on the upper end of the connecting cylinder 4107, and the lower end of the fan blade 4109 is connected to the gear set 4106.

[0051] The gear set 4106 includes a first gear 41061, a second gear 41062, a third gear 41063, and a fourth gear 41064. The first gear 41061 is connected to the upper end of the rotating arm 4105, and the second gear 41062 is meshed with the side of the first gear 41061. Thus, during the rotation and movement of the first gear 41061 with the rotating arm 4105, the meshing and rotational transmission of the second gear 41062 can be realized. The upper end of the second gear 41062 is integrally connected to the third gear 41063, and the third gear 41063 is meshed with the fourth gear 41064 on the side. The fourth gear 41064 is installed at the bottom of the connecting cylinder 4107, and the interior of the fourth gear 41064 is connected to the lower exterior of the fan blade 4109. Thus, when the fourth gear 41064 rotates, it can synchronously drive the fan blade 4109 to perform omnidirectional rotation and air blowing, thereby improving the air intake and heat dissipation quality.

[0052] Specifically, when the rotating shaft 46 rotates with the transmission of the first bevel gear 44 and the second bevel gear 45, it can also realize the rotation of the externally connected driving wheel 4101. The driving wheel 4101 can cooperate with the externally connected belt 4102 to realize the synchronous rotation of the driven wheel 4103 connected on the other side. As the driven wheel 4103 rotates, the rotating arm 4105 connected to the upper end of the driven wheel 4103 will rotate clockwise, realizing the clockwise rotation of the upper end of the first gear 41061 connected to it. When the first gear 41061 rotates clockwise, the second gear 41062 meshing with the side of the first gear 41061 will rotate counterclockwise, and the third gear 41063 connected to the upper end of the second gear 41062 will rotate in the same direction. The rotating arm 4105 engages with the fourth gear 41064 on the transmission side, causing the fourth gear 41064 to rotate clockwise. As the fourth gear 41064 rotates clockwise, the fan blade 4109, which is connected to the middle of the fourth gear 41064, rotates clockwise to blow air. Simultaneously, driven by the rotation of the rotating arm 4105 and connected to the gear set 4106, the connecting cylinder 4107, which is rotatably mounted inside the connecting frame 4108, can rotate in all directions, allowing the fan blade 4109 to blow air in all directions. This increases the range of air entering the motor body 1, enhancing heat dissipation and air circulation. It satisfies the need for air intake for heat dissipation while also providing assistance with omnidirectional air blowing, greatly improving the heat dissipation efficiency inside the motor body 1.
