EMBODIMENT EXAMPLE

[0012] Please refer to Figures 1-4 , the present invention provides a technical solution: a multifunctional disk motor, including a disk motor body 1, whose model number is De3dfBH7. The disk motor body 1 includes a stator 2 and a rotor 3. The stator 2 is equipped with an enameled copper winding 21, and the rotor 3 is equipped with a neodymium iron boron rare earth strong magnet 31. The outer periphery between the stator 2 and the rotor 3 is screwed and connected by a plurality of columns 32, which is a prior art structure. Please refer to the disk motor with the model number De3dfBH7 on the existing market.

[0013] Regarding the disk motor with the model number De3dfBH7 on the current market, which is a micro disk motor with an iron core, the coil in the disk motor lacks an external protective shell, and the enameled copper winding 21 is exposed and prone to dust accumulation, affecting the service life. The present invention installs a protective housing 4 between the stator 2 and the rotor 3. The assembly structure of the protective housing 4 is convenient for disassembly and assembly. A shielding piece is movable on the ventilation opening 41 provided in the protective housing 4, and the shielding piece can be moved according to the ventilation needs of the disk motor, facilitating ventilation and heat dissipation and also convenient for dust shielding.

[0014] The multi-functional disc motor is an improvement based on the existing disc motor with the market model De3dfBH7. One of the improvements is the assembly structure of the protective housing 4. This application also includes a protective housing 4 installed between the stator 2 and the rotor 3. Along the outer periphery of the top surface of the stator 2, there is an extended edge 47 extending upward. Along the outer periphery of the bottom surface of the rotor 3, there is a mating extended edge 48 extending downward. The protective housing 4 is clamped outside the extended edge 47 and the mating extended edge 48. A card slot 49 is formed between the extended edge 47 extending from the top surface of the stator 2 and the outer periphery of the top surface of the stator 2. A mating card slot 50 is formed between the mating extended edge 48 extending from the bottom surface of the rotor 3 and the outer periphery of the bottom surface of the rotor 3. The outer peripheries of the top surface of the stator 2 and the bottom surface of the rotor 3 both protrude, facilitating the clamping of the protective housing 4.

[0015] The multi-functional disc motor is an improvement based on the existing disc motor with the market model De3dfBH7. Another improvement is the ventilation and heat dissipation shielding structure of the protective housing 4. Ventilation openings 41 are provided on the front and back of the protective housing 4 of this application. In this embodiment, two ventilation openings 41 are provided. An arc-shaped shielding piece 44 is movably installed on the ventilation opening 41; it matches the arc of the ventilation opening 41. Guide rails 42 for the movement of the arc-shaped shielding piece 44 are respectively provided on the top and bottom surfaces of the protective housing 4. An arc-shaped guide opening 43 for the movement of the shielding piece is provided on the bottom surface of the guide rail 42. Studs 45 passing through the arc-shaped guide opening 43 are provided at the upper and lower ends of the arc-shaped shielding piece 44, and they are fixed by fixing nuts 46. Thus, the opening and closing of the shielding piece can be manually adjusted.

[0016] Specifically, when the arc-shaped shielding piece 44 and the ventilation opening 41 are manually adjusted to move to form a closed state, it is a complete shielding; When the arc-shaped shielding piece 44 and the ventilation opening 41 are manually adjusted to move to form an adjusted shielding, it is a partial shielding; When the arc-shaped shielding piece 44 and the ventilation opening 41 are manually adjusted to move to form a completely open state, it is an unshielded ventilation state.

[0017] Working principle: During use, a guide rail 42 is provided inside the protective housing 4, and an arc-shaped guide opening 43 is provided in the guide rail 42 to facilitate the movement of the arc-shaped shielding piece 44. Studs 45 provided at the upper and lower ends of the arc-shaped shielding piece 44 pass through the arc-shaped guide opening 43 and are fixed by fixing nuts 46, thereby manually adjusting and fixing the opening or closing between the arc-shaped shielding piece 44 and the ventilation opening 41. Then, the protective housing 4 is clamped between the card slot 49 formed on the bottom surface of the stator 2 and the mating card slot 50 formed on the top surface of the rotor 3.
