Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1

[0025] like Figures 1 to 4 As shown, a non-contact transmission drone water-cooled motor according to the first aspect embodiment of the present invention includes a motor housing 1, a rotor 2 installed on the inner side of the motor housing 1, a rotating shaft 4 installed on the inner side of the rotor 2, and a stator 3 installed on the outer side of the rotor 2, forming a conventional motor.

[0026] A suspension mechanism 5 is installed on the outer side of one end of the motor housing 1 to reduce the friction between the suspension mechanism 5 and the motor housing 1. The suspension mechanism 5 includes a mounting isolation cover 501. A suspension magnet 502 is installed on the inner surface of the mounting isolation cover 501 facing the motor housing 1, and another set of suspension magnets 502 corresponding to the suspension magnets 502 is installed on the outer surface of the motor housing 1 to form a magnetic levitation structure, thereby reducing the contact between the mounting isolation cover 501 and the motor housing 1 and reducing the friction.

[0027] A first magnet 12 is installed on the outer side of the rotating shaft 4, and a second magnet 13 is installed inside the motor housing 1 at the corresponding position of the first magnet 12 to support the rotating shaft 4. By using magnetic repulsion, the rotating shaft 4 is supported inside the motor housing 1, and the friction between the rotating shaft 4 and the motor housing 1 is reduced.

[0028] A water-cooling pipe 6 is provided on the inner side of the motor housing 1. A water-cooling mechanism 7 corresponding to the opening of the water-cooling pipe 6 is installed at one end of the motor housing 1 for cooling the motor housing 1. The water-cooling mechanism 7 includes a water storage tank 701. An installation ring 702 is installed inside the water storage tank 701. Several installation rods 703 are installed at equal angles on the outer side of the installation ring 702. Rubber blocks 704 facing the water-cooling pipe 6 are installed on the surface of the installation rods 703. The rubber blocks 704 and the inner wall of the water storage tank 701 are in a close-fitting sliding connection. The installation rods 703 are asymmetrically arranged on the outer side of the installation ring 702.

[0029] The inner side of the water storage tank 701 is provided with a main shaft mounting mechanism 8 that is installed at one end of the rotating shaft 4. The main shaft mounting mechanism 8 includes a mounting main shaft 801. A connecting sleeve 802 is installed at the end of the mounting main shaft 801 facing the rotating shaft 4. A second coupling block a806 corresponding to the second coupling block b11 installed on the outer side of the rotating shaft 4 is installed on the inner side of the connecting sleeve 802. An isolation sleeve 803 installed in the connecting sleeve 802 is provided between the second coupling block a806 and the second coupling block b11 to form a magnetic coupling structure, so as to avoid contact between the rotating shaft 4 and the mounting main shaft 801, avoid wear, reduce friction, and increase the kinetic energy conversion rate.

[0030] A first coupling block b804 is installed on the outer side of the connecting sleeve 802, and a first coupling block a705 installed inside the mounting ring 702 is provided at the corresponding position of the first coupling block b804.

[0031] Specifically, after the motor is started, the rotating shaft 4 rotates, causing the connecting sleeve 802 to rotate, which in turn drives the mounting shaft 801 to rotate. At the same time, the connecting sleeve 802 can also drive the mounting ring 702 to rotate. The rotation of the mounting ring 702 can cause the rubber block 704 to rotate accordingly. By utilizing the rubber block 704 to form a close sliding connection with the inner wall of the water storage tank 701, the rubber block 704 forms a seal on one end of the water cooling pipe 6 when it passes through one end of the opening. After moving away, it generates a certain degree of suction, causing the liquid at the opening to be discharged outward with the movement of the rubber block 704. This allows the liquid to remain flowing inside the motor housing 1, improving the heat dissipation effect.

[0032] Example 2

[0033] like Figure 1 and Figure 2 As shown, a non-contact transmission water-cooled motor for unmanned aerial vehicles includes all the contents of Embodiment 1. In addition, a fixing magnet 805 is installed at the lower end of the connecting sleeve 802, and a positioning magnet 503 installed on the outside of the mounting isolation cover 501 is provided at the corresponding position of the fixing magnet 805. A matching magnet b10 is installed at the upper end of the rotating shaft 4, and a matching magnet a9 installed inside the connecting sleeve 802 is provided at the corresponding position of the matching magnet b10.

[0034] Specifically, by utilizing the attraction between opposite magnetic poles of the fixed magnet 805 and the positioning magnet 503, and the repulsion between like poles of magnet a9 and matching magnet b10, the connecting sleeve 802 and the rotating shaft 4 are suspended, avoiding direct contact. Furthermore, the positioning between the first coupling block b804 and the first coupling block a705, and the positioning between the second coupling block a806 and the second coupling block b11, can further constrain the suspended connection between the rotating shaft 4 and the connecting sleeve 802.
