[0032] Reference Figure 1 and Figure 3 As shown, the utility model provides a technical solution: a brushless motor capable of dissipating heat, comprising a brushless motor body 1, a heat dissipation device 2 is provided on the outside of the brushless motor body 1, and a protective device 3 is provided on the outside of a square cover 202.

[0033] The specific settings and functions of the heat dissipation device 2 and the protective device 3 are described in detail below.

[0034] Reference Figure 2 and Figure 5 As shown, in this embodiment, the heat dissipation device 2 includes a mounting base 201, the top of which is fixedly connected to the brushless motor body 1. A square cover 202 is fixedly connected to the top of the mounting base 201. A plurality of heat dissipation holes 213 are formed on both sides of the square cover 202, and the plurality of heat dissipation holes 213 are evenly distributed on the square cover 202. A cooling fan 203 is fixedly connected to the outside of the cooling fan 203. A fixing frame 206 is fixedly connected to one side of the fixing frame 206. Two T-shaped slots 207 are formed on one side of the fixing frame 206. T-shaped plates 208 are slidably connected to the inside of the T-shaped slots 207. A connecting frame 214 is fixedly connected to one side of the two T-shaped plates 208. A dust filter 205 is fixedly connected to the inside of the connecting frame 214. When the cooling fan 203 is activated, airflow is generated. The airflow passes through the dust filter 205 to filter dust. The filtered air is then directed from the output end of the cooling fan 203 to the brushless motor body 1, thereby dissipating heat from the brushless motor body 1. A handle 209 is fixedly connected to one side of the connecting frame 214. The handle 209 has a U-shaped cross-section. This allows the handle 209 to move the connecting frame 214 when subjected to tension. A top plate 210 is fixedly connected to one end of the square cover 202. One side of the top plate 210 is fixedly connected to the brushless motor body 1. This secures the top plate 210 to the square cover 202, further securing the brushless motor body 1. Four fixing blocks 211 are fixedly connected to the inner side of the square cover 202. L-shaped heat conducting plates 212 are fixedly connected to one side of the fixing blocks 211. One side of each of the four L-shaped heat conducting plates 212 is fixedly connected to the brushless motor body 1. This secures the L-shaped heat conducting plates 212 to the brushless motor body 1, improving heat dissipation from the brushless motor body 1. Protective plates 204 are fixedly connected to the adjacent sides of the two cooling fans 203. This secures the protective plates 204 to the cooling fans 203, providing a certain degree of protection for the cooling fans 203.

[0035] Reference Figure 4As shown, in this embodiment, the protective device 3 includes four curved plates 31, one side of each of which is fixedly connected to the square cover 202. A stop plate 36 is fixedly connected to one side of each of the curved plates 31. This achieves the effect of securing the stop plate 36 to the curved plates 31, and the curved plates 31 to the square cover 202. Two telescopic rods 32 are fixedly connected to one side of the curved plates 31, and the output ends of the two telescopic rods 32 are fixedly connected to a protective plate 34. This achieves the effect of transmitting pressure applied to the protective plates 34 to the telescopic rods 32, causing the telescopic rods 32 to contract. The arc surface of the telescopic rods 32 is covered with springs 33, one end of each of the two springs 33 being fixedly connected to the protective plate 34 and the curved plate 31, respectively. This achieves the effect of preventing the springs 33 from deforming during extension or contraction of the telescopic rods 32. A rubber pad 35 is fixedly connected to one side of the protective plate 34. This achieves the effect of increasing friction.

[0036] Working principle: When it is necessary to dissipate heat for the started brushless motor, the operator first starts the cooling fan 203 through the heat dissipation device 2. The cooling fan 203 draws air from the dust filter 205. When the air passes through the dust filter 205, the dust in the air is filtered by the dust filter 205. The filtered air forms cold wind and blows toward the brushless motor body 1, thereby completing the heat dissipation of the brushless motor body 1. The heat dissipation device 2 solves the problem that the traditional brushless motor generates heat internally during operation. If it relies solely on itself for heat dissipation, the brushless motor cannot operate stably. If the heat is not dissipated in time, the service life of the brushless motor will be reduced.

[0037] Through the protective device 3, when it is necessary to prevent the brushless motor from being damaged after falling, when the brushless motor body 1 falls, the rubber pad 35 first contacts the surface of the falling place. The rubber pad 35 can offset a certain amount of impact, and the impact is transmitted to the protective plate 34, and then transmitted to the spring 33 and the telescopic rod 32 by the protective plate 34. At this time, the spring 33 and the telescopic rod 32 contract, so that the elastic force and the impact generated by the spring 33 when it contracts cancel each other out, thereby preventing the impact from being transmitted to the brushless motor body 1 and causing damage to internal components. The protective device 3 solves the problem that the traditional brushless motor is not provided with a protective component for the brushless motor, resulting in damage to the internal components of the brushless motor due to the impact when the brushless motor falls.

[0038] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
