In order to realize the purpose, the technical scheme of the utility model is as follows: a motor blade structure comprising: the blade disc and a plurality of blades, a plurality of blades encircle the blade disc and are arranged at equal intervals, one side of the blade disc close to the air inlet surface is a convex cambered surface, and orthographic projections of the blades, which are opposite to the air inlet side and the air outlet side, are not overlapped on a plane.

In the motor fan blade structure, a plurality of blades are all arc-shaped surfaces.

In the motor fan blade structure, the tail ends of the blades far away from one end of the blade disc form acute angles.

In the motor fan blade structure, the blade disc is provided with an installation part for connecting a motor shaft.

In the motor fan blade structure, the mounting part is a mounting hole.

In the motor fan blade structure, the mounting hole is provided with a fixing column close to the air inlet side.

In the fan blade structure of the motor, a plurality of blades rotate anticlockwise around the blade disc on the air inlet side.

In the motor fan blade structure, the ratio of the diameter length of the blade disc to the length of the blade is 4: 1.

In the motor fan blade structure, the blades are arranged into thirteen groups.

In the motor fan blade structure, the blades and the blade disc are integrally formed.

Through the technical scheme, the utility model has the beneficial effects that: according to the utility model, one side of the blade disc close to the air inlet surface is set to be the convex cambered surface, so that the wind can be guided to concentrate the wind power, and the air supply efficiency is improved. Meanwhile, the orthographic projections of the plurality of blades, which are right opposite to the air inlet side and the air outlet side, do not overlap on a plane, the cost of a production mold is greatly reduced, the air supply effect is improved, and the rotation resistance of the motor is reduced.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following describes a motor blade structure in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1-3, a fan blade structure of a motor includes: the blade disc 100 and a plurality of blades 200, a plurality of blades 200 encircle blade disc 100 equidistance and set up, and blade disc 100 is close to air inlet face one side and is the convex cambered surface, and the orthographic projection that a plurality of blades 200 just face air inlet side and air-out side all does not have the overlap on the plane. According to the utility model, one side of the blade disc 100 close to the air inlet surface is set to be the convex arc surface, so that the wind can be guided to concentrate the wind power, and the air supply efficiency is improved. Meanwhile, orthographic projections of the blades 200, which are over against the air inlet side and the air outlet side, are not overlapped on a plane, so that the cost of a production mold is greatly reduced, the air supply effect is improved, and the rotation resistance of the motor is reduced.

Referring to fig. 1, in the present embodiment, the plurality of blades 200 are all arc-shaped, and the convex surface is an air inlet side and the concave surface is an air outlet side.

Referring to fig. 1, in the present embodiment, the ends of the plurality of blades 200 far from the end of the blade disc 100 form acute angles, which can improve the radial air supply efficiency and reduce the lateral power loss.

Referring to fig. 1 and 3, in the present embodiment, a mounting portion 110 is disposed on the blisk 100 for connecting a motor shaft.

In this embodiment, the mounting portion 110 is a mounting hole through which the motor shaft can be fixed to the mounting portion.

In this embodiment, the mounting hole is equipped with a fixed column near the air inlet side, can make the motor shaft fix in the fixed column, and is more firm.

Referring to fig. 1, in the present embodiment, the plurality of blades 200 rotate counterclockwise around the blade disc 100 on the air inlet side, which is beneficial to improving the air supply efficiency.

Referring to fig. 2, in the embodiment, the ratio of the diameter length of the blisk 100 to the length of the blades 200 is 4:1, and compared with the blades of the existing motor, the diameter length of the blisk 100 in the present application is much greater than the length of the blades 200, which can greatly increase the air supply amount, reduce the mold cost of the blades 200, and reduce the wind resistance suffered by the motor.

Referring to fig. 1-2, in the present embodiment, twelve groups of blades 200 are provided, so as to have a good noise reduction effect.

Referring to fig. 1-2, in the present embodiment, the blades 200 are integrally formed with the blade disc 100, so as to increase the production efficiency and reduce the production cost.
