Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
As shown in Figures 1 to 4, electric machine assembly 100 of the present utility model, including motor 1 with in order to be located at the Novel noise reduction motor cover 2 outside described motor 1.
Described motor 1 is in column, and two brushes 11 including being arranged on opposite sides and four the second air outlets 12.Four described second air outlets 12 are separately positioned on the both sides of two brushes 11, and described second air outlet 12 is in order to discharge the air-flow of described motor 1.
Described motor cover 2 include upper outlet body 21, lower cover 22, from 23, two peristomes 24 of first gear aerofoil of the downward-sloping setting in described lower cover 22 top and two the first air outlets 25 being arranged on lower cover 22.Two described first air outlets 25 are arranged on the opposite sides of described motor cover 2, therefore, when air-flow flows out from two described first air outlets 25, and described electric machine assembly 100 still stress equalization, it is not likely to produce and rocks.Two described peristomes 24 are separately positioned on the top of two described first air outlets 25.
Described upper outlet body 21 and lower cover 22 are provided with second gear aerofoil 211, and described lower cover 22 is provided with blocking part 221, and described blocking part 221 is arranged on the top of described first air outlet 25.The quantity of described second gear aerofoil 211 is four, and described blocking part 221, upper outlet body 21 and two second gear aerofoils 211 form a peristome 24, and four described second gear aerofoils 211 are separately positioned on the both sides of two described peristomes 24.When described motor cover 2 be located at described motor 1 outer time, described brush 11 is placed in described peristome 24.
The quantity of described first gear aerofoil 23 is four, and each described first gear aerofoil 23 is all connected with a described second gear aerofoil 211.Described first gear aerofoil 23 interval arranges and is formed with two vents 28, and described vent 28 is arranged on and the described peristome 24 position in 90 °.
When described motor cover 2 be located at motor 1 outer time, described upper outlet body 21, first gear aerofoil 23 and motor 1 enclose and set formation the first air channel 26, described lower cover 22, first gear aerofoil 23 and motor 1 enclose and set formation the second air channel 27, and described vent 28 is in order to connect the first air channel 26 and the second air channel 27.Described second air outlet 12 is connected with described first air channel 26, and described first air channel 26 is connected with the second air channel 27, and described second air channel 27 is connected with the first air outlet 25.Therefore, the motor cover 2 of present patent application, form double; two air channel structure, it is possible to make the air-flow flowed out from described second air outlet 12, after flowing through the first air channel 26 and the second air channel 27, flow out from the first air outlet 25, extend air-flow outflow path.
