[0019] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.
[0020] This application discloses a connection structure between a stator and a base, including a base body 1. Two symmetrical fixing seats are provided at the bottom of the base body 1. The outer wall of the base body 1 is provided with uniformly arranged heat sinks 2. The stator body 3 is provided inside the base body 1. The inner wall of the base body 1 has four identical limiting grooves 4, which are opposite to each other in pairs. The base body 1 also has a connection structure. The stator body 3 is installed inside the base body 1 through the connection structure. The inner wall of the base body 1 is also provided with multiple heat dissipation ports 5 between the four limiting grooves 4. The heat dissipation ports 5 are connected to the heat sinks 2.
[0021] Reference 1. Figure 2 and Figure 3 The connecting structure includes four positioning posts 6, which are installed in four limiting grooves 4 opened in the inner wall of the base body 1. One end of the positioning post 6 is connected to one end of the inner wall of the base body 1, and the other end of the four positioning posts 6 passes through the through holes opened at both ends of the four protrusions 7 provided in the outer wall of the stator body 3. A fixing component is also provided on one side of the four protrusions 7 at the other end of the positioning post 6. The fixing component includes four nuts 8, which are rotatably adapted to the threaded grooves opened in one end of the four positioning posts 6. Four washers 9 are also provided on one side of the nuts 8 on the positioning post 6. The other side of the four gaskets 9 is attached to one end of the four protrusions 7. More specifically, the four protrusions 7 on the outer wall of the stator body 3 are slid along the four limiting grooves 4 opened on the inner wall of the base body 1 to the inside of the base body 1, so that one end of the four positioning pins 6 in the limiting grooves 4 passes through the fixing holes opened at both ends of the four protrusions 7, thereby limiting the stator body 3. Then, by limiting the other end of the positioning pins 6 with the four nuts 8 and the four gaskets 9, the stator body 3 is fixedly installed in the base body 1, making the stator body 3 more firmly fixed.
[0022] refer to Figure 4 The four protrusions 7 on the outer wall of the stator body 3 are adapted to the four limiting grooves 4 on the inner wall of the base body 1. The outer wall of the stator body 3 is also provided with multiple heat dissipation grooves 10 between the four protrusions 7. The heat dissipation grooves 10 correspond to the heat dissipation openings 5 on the inner wall of the base body 1. The inner wall of the stator body 3 is also provided with multiple stator grooves 11 arranged evenly. More specifically, by providing multiple heat dissipation grooves 10 on the outer wall of the stator body 3, the heat dissipation grooves 10 correspond to the heat dissipation openings 5 on the inner wall of the base body 1. Since the heat dissipation openings 5 are connected to the heat dissipation fins 2 provided on the outer wall of the base body 1, it is convenient to transfer the heat generated inside the stator body 3 to the heat dissipation fins 2 for heat dissipation, thereby improving the heat dissipation effect.
[0023] The implementation principle of the stator-base connection structure in this application embodiment is as follows: In use, the stator body 3 is slid into the base body 1 through the four limiting grooves 4 opened on the inner wall of the base body 1 via the four protrusions 7 set on the outer wall. One end of the four positioning pins 6 set in the limiting grooves 4 passes through the fixing holes opened at both ends of the four protrusions 7, thereby limiting the stator body 3. Then, the other end of the positioning pins 6 is limited by the four nuts 8 and four washers 9, thereby fixing the stator body 3 inside the base body 1, making the stator body 3 more firmly fixed. While fixing the stator body 3, the heat dissipation grooves 10 opened on the outer wall of the stator body 3 correspond to the heat dissipation vents 5 opened on the inner wall of the base body 1. Since the heat dissipation vents 5 are connected to the heat dissipation fins 2 set on the outer wall of the base body 1, the stator body 3 can easily transfer the heat generated inside to the heat dissipation fins 2 for heat dissipation, thereby improving the heat dissipation effect.
[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
