[0040] Specifically, the left end of the top of the rear side of the magnetic suspension clutch 1 is provided with a mounting hole 3, which provides a position for the installation of the heat dissipation assembly. Inside the mounting hole 3, the heat dissipation pipe 4 is smoothly and slidably connected. This heat dissipation pipe 4 is used for efficient heat dissipation of the magnetic suspension clutch 1. The rear end of the heat dissipation pipe 4 is provided with an air inlet 5 for air to enter. The front side of the air inlet 5 is fixedly connected with an air inlet funnel 8, which can effectively expand the air intake area of the air inlet 5, so that more air can quickly flow in.

[0041] Referring to Figure 5 , the mounting mechanism 2 includes a fixed frame 201 fixedly connected to the bottom of the outer wall of the magnetic suspension clutch 1 at the top. It provides a support for installation. The inside bottom of the fixed frame 201 is provided with a circular hole 202 at both ends. The top of the two circular holes 202 is provided with a bolt 203.

It prevents the bolt 203 from being tightened and unable to turn. The bottom of the fixed frame 201 is fixedly connected with two positioning columns 205, which are used for positioning during installation.

[0042] Specifically, the top of the fixing frame 201 is fixed at the bottom of the outer wall of the magnetic floating clutch 1, providing a stable and reliable support for the entire installation. Circular holes 202 are formed at the bottom of the inner side of the fixing frame 201, and bolts 203 are provided at the top of the two circular holes 202. By means of these bolts 203, the fixing frame 201 can be fixed at a designated position in the vehicle, ensuring the stable installation of the magnetic floating clutch 1. Threaded sleeves 204 are connected to the outer wall of the two bolts 203, which can effectively prevent the bolts 203 from being too tightly fastened and causing difficulty in rotation. The bottom of the fixing frame 201 is also fixedly connected with two positioning columns 205, which can accurately position during installation, greatly improving the accuracy and convenience of installation.

[0043] With reference to Figure 1 , Figure 2 and Figure 3 , a plurality of guide grooves 10 are formed in the middle of the front side of the magnetic floating clutch 1, and a plurality of guide strips 11 are fixedly connected to the outer wall of the two positioning columns 205 for guiding and preventing rotation. A fixed plate 12 is fixedly connected to the lower middle of the rear side of the magnetic floating clutch 1, and a warning sign 13 is fixedly connected to the rear side of the fixed plate 12 for reminding people to use safely. An inclined strut 14 is fixedly connected to the top of the rear side of the magnetic floating clutch 1, and a fixed sleeve 15 is fixedly connected to the bottom of the inclined strut 14 for fixing the position of the heat dissipation pipe 4.

[0044] Specifically, a plurality of guide grooves 10 are formed in the middle of the front side of the magnetic floating clutch 1, and a plurality of guide strips 11 are fixedly connected to the outer wall of the two positioning columns 205 for accurate guidance and preventing the magnetic floating clutch 1 from rotating during work, ensuring stable operation. A fixed plate 12 is fixedly connected to the lower middle of the rear side of the magnetic floating clutch 1, and a warning sign 13 is fixedly connected to the rear side of the fixed plate 12 for reminding people to use safely. An inclined strut 14 is fixedly connected to the top of the rear side of the magnetic floating clutch 1, and a fixed sleeve 15 is fixedly connected to the bottom of the inclined strut 14 for fixing the position of the heat dissipation pipe 4, ensuring the normal operation of the heat dissipation system and improving the safety and practicality of the magnetic floating clutch 1.

[0045] With reference to Figure 1 and Figure 4 , a protective shell 16 is fixedly connected to the top of the outer wall of the magnetic floating clutch 1. The protective shell 16 is designed to be smooth, which is used to protect the internal wires. The plurality of guide grooves 10 are arranged at equal intervals, and the sizes of the plurality of guide strips 11 are consistent. The diameter of the heat dissipation pipe 4 is smaller than the diameter of the installation hole 3, and the diameter of the rear side of the air inlet funnel 8 is equal to the diameter of the air inlet 5.

[0046] Specifically, the outer wall top of the magnetic floating clutch 1 is provided with a protective shell 16, and the smooth design can effectively protect the internal wires, prevent the wires from being damaged due to external scratching and collision, and avoid safety hazards caused by sharp corners. A plurality of guide grooves 10 are arranged at equal intervals, and a plurality of guide strips 11 with consistent sizes are matched, so as to ensure accurate guidance and stable operation. The diameter of the heat dissipation pipe 4 is smaller than that of the mounting hole 3, so that the heat dissipation pipe 4 can smoothly slide in the hole. The diameter of the rear side of the air inlet funnel 8 is equal to that of the air inlet 5, so as to ensure seamless connection during the air inlet process.

[0047] Working principle: Under the guidance of the air inlet funnel 8, a large amount of air can quickly flow into the air inlet 5 due to the expansion of the air inlet area, enter the heat dissipation pipe 4, and flow out through the evenly distributed heat dissipation holes 7 in the outer wall during the flow process in the pipe. These air flowing out of the heat dissipation holes 7 directly blows the inside of the magnetic floating clutch 1, taking away the heat generated by the operation of the clutch, realizing all-round heat dissipation of the inside. The plurality of heat dissipation fins 9 fixed on the front side of the outer wall of the magnetic floating clutch 1 greatly increase the heat dissipation area. The hot air flowing out of the heat dissipation pipe 4 and completing heat dissipation inside the clutch further dissipates heat to the surrounding environment through the heat dissipation fins 9 during passing through the heat dissipation fins 9. During the whole process, the heat dissipation pipe 4 and the heat dissipation fins 9 cooperate with each other, air continuously flows into the air inlet 5, flows out through the heat dissipation holes 7, and then is discharged from the air outlet 6 after secondary heat dissipation through the heat dissipation fins 9. The process is continuously circulated, which greatly enhances the overall heat dissipation effect of the magnetic floating clutch 1 and guarantees its stable operation.

[0048] Moreover, the two positioning columns 205 at the bottom of the fixing frame 201 fit the pre-set installation position in the vehicle, quickly determining the horizontal and vertical positions of the fixing frame 201 in the vehicle, improving the accuracy of the initial installation stage. The bolt 203 is passed through the round holes 202 at the left and right ends of the inner bottom of the fixing frame 201 and is screwed with the corresponding threaded holes in the vehicle. During the screwing process of the bolt 203, the gasket 204 plays a buffering and anti-locking role. With the gradual tightening of the bolt 203, the gasket 204 uniformly disperses the pressure applied by the bolt 203 by virtue of its elastic deformation, avoiding excessive local pressure that causes the bolt 203 to be too tightly engaged with the threaded hole. When all the bolts 203 are tightly fastened in place, the fixing frame 201 fixes the magnetic floating clutch 1 in the vehicle. The top of the fixing frame 201 stably supports the bottom of the outer wall of the magnetic floating clutch 1, resisting external disturbances such as vibration and bumping during vehicle driving, and ensuring that the magnetic floating clutch 1 always maintains a stable installation state.

[0049] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
