Referring to fig. 2 and 3, the stator base 11 has an air inlet 111, a first through hole 112, a first sealing groove 113, and a second sealing groove 114. The air inlet 111 is disposed at the base of the stator base 11 and penetrates through the stator base 11, so that the inside of the stator base 11 communicates with the outside. The air inlet 111 is used for allowing external air flow to enter the interior of the stator seat 11, so that heat generated by the stator winding 12 in operation is dissipated to the outside, the temperature of the stator winding 12 is reduced, and the rotation performance of the rotor 14 is improved. The first wire through hole 112 is disposed at the bottom of the stator seat 11, the first wire through hole 112 also penetrates through the stator seat 11, and the first wire through hole 112 is used for a cable of the power supply module 30 to penetrate through the stator seat 11 so as to be electrically connected with the stator winding 12.

The second sealing element 50 may be a potting compound or a conventional rubber ring.

Referring to fig. 4, the rotor 14 is provided with a fan blade 141 and an air outlet 142. The fan blade 141 is disposed on the surface of the rotor 14 facing the stator seat 11 and protrudes toward the stator seat 11, the air outlet 142 is disposed on the edge of the rotor 14, and the air outlet 142 communicates the inside of the rotor 14 with the outside. When the rotor 14 rotates relative to the stator seat 11, the fan blades 141 may generate negative pressure, so that external airflow is sucked into a chamber enclosed by the stator seat 11 and the rotor 14 from the air inlet 111 on the stator seat 11, and heat generated by the stator winding 12 in the working process is blown out from the air outlet 142 of the rotor 14, so as to reduce the temperature in the chamber and prevent the working performance of the stator winding 12 from being affected by an excessively high temperature.

The fan blade 141 includes a first blade 1411. Wherein the first blade 1411 extends in a radial direction of the rotor 14, and both ends of the first blade 1411 are connected to an edge of the rotor 14 and a center of the rotor 14, respectively. The number of the first blades 1411 may be one, two, or more, and when the number of the first blades 1411 is two or more, for the purpose of the gravity center balance of the rotor 14 and the heat dissipation effect of the first blades 1411, a plurality of first blades 1411 may be disposed on the surface of the rotor 14 in a symmetrical or circumferential array. In order to further accelerate the heat dissipation effect in the chamber, a plurality of air outlets 142 may be provided, and preferably, one air outlet 142 may be provided between two adjacent first blades 1411, so that each first blade 1411 may correspond to one air outlet 142, thereby accelerating the circulation of the airflow.

It is understood that in other embodiments, the fan blade 141 may also include a second blade 1412. The second vane 1412 extends from an edge of the rotor 14 toward a center direction of the rotor 14, and a length of the second vane 1412 is smaller than that of the first vane 1411 in a radial direction of the rotor 14. Since the plurality of first vanes 1411 are distributed in a spot-shot manner, that is, the distance between the ends of two adjacent first vanes 1411 close to the rotation center of the rotor 14 is smaller than the distance between the ends close to the edge of the rotor 14, that is, the pressure of the airflow gradually decreases from the rotation center of the rotor 14 to the edge of the rotor 14. However, the excessive arrangement of the first blades 1411 causes the distance between two adjacent first blades 1411 near the rotation center end of the rotor 14 to be too small, and the driving pressure for the airflow is greatly reduced. Therefore, in order to ensure smooth flow of the airflow, a second vane 1412 may be disposed at one end of two adjacent first vanes 1411 near the edge of the rotor 14 to further pressurize the airflow. On the other hand, the length of the second blade 1412 is smaller than that of the first blade 1411, which can also effectively reduce the weight of the rotor 14, and thus the weight of the entire power sleeve mechanism 100, and is very beneficial to the use scenario of the power sleeve mechanism 100.
