[0024] As Figures 1 to 3 shown, an embodiment of the present utility model provides a noise reduction housing for a high-speed motor, including a motor housing 2:

[0025] On both sides of the bottom end of the motor housing 2, there are T-shaped support frames 3 threadedly connected. The bottom ends of the two T-shaped support frames 3 are fixedly connected to the bottom of the inner wall of the U-shaped housing frame 1. On both sides of the inner wall of the U-shaped housing frame 1, there are a plurality of threaded holes 5. Threaded columns 7 are threadedly connected inside the plurality of threaded holes 5. One end of each threaded column 7 is fixedly provided with a buffer rubber column 4. The inner wall of the motor housing 2 is provided with a polyethylene layer 16. The inner wall of the polyethylene layer 16 is fixedly provided with a first aluminum alloy honeycomb structure layer 17. The inner wall of the first aluminum alloy honeycomb structure layer 17 is fixedly connected to the second aluminum alloy honeycomb structure layer 14 through a plurality of rubber shock absorbers 15. The inner wall of the second aluminum alloy honeycomb structure layer 14 is fixedly provided with a fiberglass layer 13. The fiberglass layer 13 is fixedly arranged on the outer wall of the high-speed motor 12.

[0026] Specifically, at the other end of each of the plurality of threaded columns 7, there is a knob column 6 fixedly provided.

[0027] Specifically, on the outer wall of the output rotor of the motor housing 2, there is an annular groove 8. The inner wall of the annular groove 8 is provided with an internal thread groove 11. The internal thread groove 11 is threadedly connected to a threaded ring column 9. The threaded ring column 9 is fixedly arranged at the tail of the sleeve column 10.

[0028] Specifically, the inner wall of the sleeve column 10 is coated with a damping coating.

[0029] Specifically, the plurality of rubber shock absorbers 15 are arranged in an array on the first aluminum alloy honeycomb structure layer 17 and the second aluminum alloy honeycomb structure layer 14.

[0030] Working principle: The vibration energy generated during the operation of the high-speed motor 12 is first transmitted to the fiberglass layer 13. The fiberglass layer 13, through its good shock absorption performance, initially absorbs a part of the vibration energy. The vibration energy is transmitted to the rubber shock absorbers 15 between the second aluminum alloy honeycomb structure layer 14 and the first aluminum alloy honeycomb structure layer 17. The rubber shock absorbers 15 absorb and convert the remaining vibration energy. The first aluminum alloy honeycomb structure layer 17 and the second aluminum alloy honeycomb structure layer 14 further disperse and reduce the vibration. The polyethylene layer 16 has good sound insulation performance and can effectively block and absorb the remaining noise, reducing the transmission of noise. The buffer rubber column 4 is fixed on the threaded column 7 and can absorb the vibration transmitted from the motor, reducing the vibration transmitted to the outside through the support structure. The damping coating on the inner wall of the sleeve column 10 absorbs the vibration energy generated by the rotation of the remaining rotor, reducing the transmission of noise and vibration. The solution can effectively absorb and convert the vibration energy generated during the operation of the high-speed motor 12, and through the blocking and absorption of multiple layers of materials, significantly reduce the noise and improve the noise reduction effect of the motor housing 2.

[0031] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other, and the key point of each embodiment is to illustrate the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can refer to the partial description of the method embodiment.

[0032] The above description is only for the embodiments of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
