The disclosure relates to a technical field of driving devices, in particular to a stator structure and a motor.
When a motor rotates at a high speed, there are very strict requirements on coaxiality among fan blades, a rotor, an air duct, bearings, and bearing chocks in the motor. Poor coaxiality will lead to the generation and expansion of the vibration noise of the motor and affect the service life of the motor. At present, the motor used in the ventilation duct includes an air duct and a necessary motor assembly installed in the air duct. In order to ensure the coaxial consistency between the air duct and the motor assembly, an inner wall of the air duct needs to be processed. In an existing motor processing and assembly process, the fan blades, the stator and the rotor can be assembled at the same time on both sides of the air duct, which can improve the assembly efficiency; however, the coaxiality among the fan blades, the rotor, the stator and an air duct housing is difficult to be achieved by the assembly, and processing accuracy of the inner wall of the air duct is relatively low. At present, a high speed rotation of the motor requires higher coaxial consistency and more accurate processing. The processing accuracy of the prior art can no longer meet the high requirements for the motor assembly. An existing air duct is shown in
A purpose of the disclosure is to provide a stator structure and a motor to solve technical problems described in above background.
To achieve the above purpose, the disclosure provides a technical scheme described below.
A stator structure, including an air duct housing, a fixing part, connecting components, and a mounting end cover. The fixing part is coaxially disposed in the air duct housing and configured to install a motor assembly, the connecting components are disposed between the air duct housing and the fixing part, the connecting components are configured to fix a relative position between the air duct housing and the fixing part, a position of a mounting inlet provided by the fixing part is on a same side as a position of a fan blade assembly disposed in the air duct housing, an end of the fixing part far away from the mounting inlet is provided with the mounting end cover.
A motor, including the stator structure described above. The motor further includes the motor assembly and the fan blade assembly, the motor assembly is disposed in the fixing part, an output end of the motor assembly is provided with the fan blade assembly, the fan blade assembly includes arcuate fan blades and a fan blade housing, and the fan blade assembly is disposed in the air duct housing.
The disclosure has following beneficial effects.
1. By setting the mounting inlet provided by the fixing part and the fan blade assembly disposed in the air duct housing on a same side, processing of surfaces A, B and C can be completed by one processing without secondary processing, therefore ensuring coaxiality of the air duct.
2. Since a position of the mounting inlet provided by the fixing part and a position an air inlet provided by the air duct housing are on the same side, a front end cover needs to be installed, and an installation position of the front end cover corresponds to the surface B. Therefore, the disclosure does not need to process the surface D′ surface existed in the existing air duct, therefore reducing processing steps and improving the processing efficiency and accuracy of processing coaxiality.
Other features and advantages of the disclosure will be explained in detail in specific embodiments.

The disclosure improves on a defect that the coaxial consistency of an air duct in the prior art cannot be guaranteed, the disclosure specifically includes an air duct housing 1 and a fixing part 2, the fixing part 2 is coaxially disposed in the air duct housing 1 and configured to install a motor assembly 6. An air duct of the disclosure differs from the prior art is described below. An end of the fixing part 2 far away from a mounting inlet 21 is provided with a mounting end cover 3, there is no barrier among surface A of an inner wall of the air duct housing 1, surface B of an inner wall of the fixing part 2 and surface C of an inner wall of the mounting end cover 3; the three surfaces are set on a same side while the three surfaces are coaxial surfaces, where the surface A refers to the inner wall of the air duct housing 1, the surface A can provide an installation position for a fan blade assembly 7, the surface B refers to the inner wall of the fixing part 2, the surface B can provide an installation position for the motor assembly 6, the surface C refers to the inner wall of the mounting end cover 3, the surface C can provide an installation position for a bearing 8. During processing, the processing can be carried out in the order of the surfaces A, B, and C; or in the order of the surfaces C, B, and A; or in other orders, this is not a limitation to the disclosure. It can be determined that the processing of the surfaces A, B and C can be completed by one processing without secondary processing, therefore ensuring coaxiality of the air duct.

In the disclosure, since the mounting inlet 21 provided by the fixing part 2 and an air inlet provided by the air duct housing 1 are on the same side, a front end cover 62 needs to be installed, and an installation position of the front end cover 62 corresponds to the surface B. Therefore, the disclosure does not need to process the surface D′ existed in the existing air duct. The disclosure reduces processing steps and improves the processing efficiency and accuracy of processing coaxiality.
The air duct of the disclosure needs to be used in conjunction with the motor assembly 6 to form a motor applied in a hair dryer or an air comb. An output end of the motor is provided with the fan blade assembly 7, the fan blade assembly 7 includes arcuate fan blades 71 and a fan blade housing 72, the fan blade housing 1 is configured to fix the arcuate fan blades 71. The fan blade housing 72 is sleeved at a rear end of the motor assembly 6. When the motor drives the fan blade assembly 7 to rotate, external air enters from the air inlet of the air duct through the arcuate fan blades 71 speed up the wind, the air passes through a gap between the air duct housing 1 and the fixing part 2, and then the air is blown out from an air outlet to provide faster and smoother wind, this means that air can form air flow to flow in the air duct by the arcuate fan blades 71 driven by the motor, therefore, a connection between the duct housing 1 and the fixing part 2 is not important. For example, some fixing columns (not shown in the figures) extending in an axial direction are provided on the inner wall of the air duct housing 1. The fixing columns form supports to connect and fix the air duct housing 1 to the fixing part 2. Or air deflectors 4 extending in the axial direction are provided on the inner wall of the air duct housing 1, which can also fix a relative position between the air duct housing 1 and the fixing part 2. In the embodiment, connecting components may be the air deflectors 4 arranged in a circular array to fix the relative position between the air duct housing 1 and the fixing part 2, shapes of the air deflectors 4 are arc respectively, and the air deflectors 4 are oriented in a same direction, which can achieve a good fixing effect and guide the air flow to improve the air outflow effect.

Due to the fixing method of a rear end cover used in the prior art, machining escape holes 31 at a position of the rear end cover is needed. In the embodiment, while the air duct housing 1 is assembled to obtain a complete air duct, machining and forming the escape holes 31 directly at the position of the mounting end cover. Therefore, no additional process of the front end cover 62 is required, which improves an overall production efficiency.
In the embodiment, in order to enhance the strength between the mounting end cover 3 and the fixing part 2, there are some reinforcing ribs 5 disposed at a connecting position between the mounting end cover 3 and the fixing part 2. In addition, in the disclosure, an end of the fixing part 2 far away from the air inlet is disposed outside the air duct housing 1.
