[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] Embodiment 1

[0022] The present utility model provides a power motor for a drone, as Figures 1 to 5As shown in the figure, it includes a housing 1. A sealing groove 2 is provided at the top end of the housing 1. A sealing plate 3 is clamped at the position inside the sealing groove 2 at the top end of the housing 1. A sealing gasket 4 is fixedly connected to the bottom end of the sealing plate 3. A fixing cover 5 is fixedly connected to the top end of the sealing plate 3. A support frame 6 is fixedly connected to the inner bottom surface of the housing 1. A rotating shaft 8 is fixedly installed at the position inside the housing 1 and inside the support frame 6. The rotating shaft 8 is movably connected to the inside of the fixing cover 5. A first heat dissipation hole 9 is provided at the position outside the rotating shaft 8 at the top end of the fixing cover 5. A stator 10 is clamped inside the housing 1. A bearing 11 is movably connected to the inside of the stator 10. A second heat dissipation hole 12 is provided at the position outside the bearing 11 at the top end of the stator 10.

[0023] As Figure 1 and Figure 3 shown in the figure, a fixing sleeve 13 is sleeved inside the stator 10. Four positioning rods 14 are fixedly connected to the position at the top end inside the fixing sleeve 13. One end of each of the four positioning rods 14 is fixedly connected to a positioning disc 15. The bottom end surface of the bearing 11 is attached to the top end surface of the positioning disc 15. Four guiding grooves 16 are provided inside the positioning disc 15 to ensure that the clamping block 18 is clamped into the inside of the clamping groove 17 without being blocked by the positioning disc 15, ensuring the normal use of the clamping block 18.

[0024] As Figure 1 and Figure 5 shown in the figure, four clamping grooves 17 are provided inside the bearing 11. A clamping block 18 is clamped at the position of the clamping groove 17 inside the bearing 11. One end of the clamping block 18 is fixedly connected to the outer surface of the rotating shaft 8. Through the combination of the clamping block 18 and the clamping groove 17, it is ensured that the rotation of the rotating shaft 8 drives the bearing 11 to rotate synchronously.

[0025] As Figure 1 and Figure 2 shown in the figure, the sealing gasket 4 is made of rubber. Extruding the rubber can seal the sealing groove 2, enhancing the sealing performance of the fixing cover 5.

[0026] As Figure 1 and Figure 5 shown in the figure, the diameter of the bearing 11 is the same as the diameter inside the positioning disc 15. The precise fit between the bearing 11 and the positioning disc 15 can ensure that the bearing 11 is fixed inside the positioning disc 15, improving the stability of the overall structure.

[0027] As Figure 1 and Figure 3 shown in the figure, the clamping block 18 and the clamping groove 17 have the same size. The combination of the clamping block 18 and the clamping groove 17 can ensure the stable position of the rotating shaft 8 and enhance the stability of the rotating shaft 8.

[0028] Working principle: During the actual use of the device, first, the fixing sleeve 13 is sleeved onto the outer surface of the rotating shaft 8, and then the stator 10 is also sleeved onto the outer surface of the rotating shaft 8. At this time, the bottom end of the bearing 11 fits against the top surface of the positioning disk 15. Then, the clamping block 18 is snapped into the internal card slot 17. At this moment, the rotating shaft 8 is fixed. The rotation of the rotating shaft 8 can drive the bearing 11 to rotate synchronously, which can enhance the firmness inside the motor, prevent the internal components of the motor from loosening due to long-term rotation of the motor, thus affecting the normal use of the motor, and improve the stability of the motor;

[0029] Then, align the sealing plate 3 at the bottom end of the fixing cover 5 with the sealing groove 2, and press down the fixing cover 5 so that the sealing plate 3 is snapped into the internal sealing groove 2. Then, the sealing gasket 4 will completely seal the inside of the sealing groove 2, which can effectively seal, prevent dust and tiny particles from entering the inside of the motor, causing wear and blockage, and can prevent moisture from invading, protecting the motor from the influence of a humid environment, improving the reliability and durability of the motor. Then, during the use of the motor, through the first heat dissipation holes 9 and the second heat dissipation holes 12, the air circulation inside the motor can be ensured, thereby enhancing the heat dissipation efficiency of the motor.

[0030] The above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit it.
