Description

Technical Field

[0001] This utility model relates to the field of cooling fan technology, specifically to a stator anti-rotation structure for a cooling fan. Background Technology

[0002] With the trend of electronic products becoming thinner and more lightweight and higher performance, the heat generated by their electronic components is also gradually increasing. In order to avoid excessive heat affecting the user experience, the demand for cooling fans is also increasing. When the cooling fan is running, the stator is stationary and the rotor moves to drive the outer fan blades to rotate and generate airflow to achieve a cooling effect. However, due to the characteristics of electromagnetics, if the stator and the middle tube are not installed securely, relative motion will occur, causing the stator to rotate and affecting the subsequent cooling effect. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a stator anti-rotation structure for a cooling fan. The structure is simple and easy to use. When used inside the fan, the stator and the central tube will not move relative to each other, thus preventing the stator from rotating relative to the tube. This results in good performance.

[0004] To solve the above-mentioned technical problems, this utility model provides a stator anti-rotation structure for a cooling fan, including a stator assembly, a tube disposed inside the stator assembly, a positioning post disposed on the inner side of the stator assembly near the tube, a first groove adapted to the stator assembly near the positioning post, and a second groove adapted to the stator assembly near the positioning post.

[0005] Furthermore, the cross-section of the first groove is semi-circular.

[0006] Furthermore, the opening of the second groove corresponds to the opening of the first groove, and its cross-section is also semi-circular.

[0007] Furthermore, the bottom of the pipe is provided with an integrally formed base.

[0008] The beneficial effects of this utility model are as follows: The first groove of this structure has a semi-circular cross section, and the opening of the second groove corresponds to the first groove and also has a semi-circular cross section. It is compatible with the positioning post and ensures that the two sides of the positioning post are placed between the first groove and the second groove respectively without relative displacement. When the fan is running, the tube is fixed. Therefore, the stator will not move relative to the tube due to the locking effect of the positioning post, that is, it is locked and will not move.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0014] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0018] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0019] Reference Figures 1 to 3 As shown, an embodiment of the anti-rotation structure for a cooling fan according to the present invention includes a stator assembly 1, a tube 2 disposed inside the stator assembly 1, a positioning post 3 disposed on the inner side of the stator assembly 1 near the tube 2, a first groove 11 adapted to the stator assembly 1 near the positioning post 3, and a second groove 21 adapted to the tube 2 near the positioning post 3.

[0020] The first groove 11 has a semi-circular cross-section, and the opening of the second groove 21 corresponds to the first groove 11 and also has a semi-circular cross-section. It is adapted to the positioning post 3 to ensure that the two sides of the positioning post 3 are placed between the first groove 11 and the second groove 21 respectively without relative displacement. When the fan is running, the tube 2 is fixed. Therefore, the stator will not move relative to the tube 2 due to the locking effect of the positioning post 3, that is, it is locked and will not move.

[0021] The bottom of pipe 2 is equipped with an integrated base, which is compatible with the subsequent installation and use of the cooling fan.

[0022] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
