Description
Technical Field
The utility model belongs to the technical field of fans, and particularly relates to an integral rotor structure for a fan.
Background
The working principle of the air conditioner for the automobile is that the replacement of air is achieved through the operation of a fan arranged in the air conditioner (the air per se is not flowed, and the air conditioner realizes the flow conversion of cold air and hot air through the rotation of a fan of the fan, so that the change of the temperature in the automobile which is increased or decreased according to the requirement is met); the automobile air-conditioning fan consists of three parts, namely a rotor, a stator and fan blades, wherein the rotor serving as a key part consists of a central shaft, a shell, a permanent magnet (magnetic steel), a fixing clamp and 5 large parts of a fastening piece. The production and manufacturing of the traditional fan rotor can only be solved by improving the precision of parts and strengthening the quality monitoring in the installation process, but the effect is not good, and the reject ratio of the product is always high. The production cost of the enterprise is increased, and meanwhile, the reputation of the enterprise is also adversely affected
Therefore, there is a need for a rotor structure for an integrated wind turbine to solve the above problems.

Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.
Please refer to fig. 1-2. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship which the products of the present invention are usually placed in when used, which is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.
In the description of the present invention, it should be further noted that, unless otherwise specifically stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a communication between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
