[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 A precision axial flux stator for new energy vehicles includes a stator core 1 and several pluggable positioning blocks 2 disposed at the bottom of the stator core 1. A housing mounting plate 100 is disposed at the bottom of the stator core 1.

[0019] Furthermore, winding storage cavities 13 are evenly spaced around the inner wall of the stator core 1.

[0020] A positioning groove 3, which is adapted to the positioning block 2, is provided on the bottom surface of the stator core 1 and at the position corresponding to the positioning block 2. The side of the positioning block 2 near the positioning groove 3 passes through the positioning groove 3 and extends into the interior to contact the inner wall of the positioning groove 3. A sliding groove 4 is provided on the top of the housing mounting plate 100 and at the position corresponding to the positioning block 2. A sliding rod 5 is fixedly connected to the inner wall of the sliding groove 4. A slider 6 is slidably connected to the surface of the sliding rod 5. The top of the slider 6 is fixedly connected to the bottom of the positioning block 2, and the bottom of the positioning block 2 is in sliding contact with the top of the housing mounting plate 100.

[0021] The top of the housing mounting plate 100 has an annular groove 7. A movable annular limiting plate 8 is installed inside the annular groove 7. The top of the annular limiting plate 8 passes through the annular groove 7 and extends to its outside. The surface of the annular limiting plate 8 slides in contact with the inner wall of the annular groove 7. The side of the annular limiting plate 8 closest to the positioning block 2 contacts the positioning block 2. The annular limiting plate 8 serves to limit the movement of several positioning blocks 2. A fastening bolt 9 is provided on the left side of the annular limiting plate 8 and threadedly connected to the positioning block 2 located on the left. A movable... Block 10, the housing mounting plate 100 has a fixed groove 11 inside and corresponding to the position of the movable block 10. The bottom of the movable block 10 passes through the annular groove 7 and the fixed groove 11 from top to bottom and extends into the interior of the fixed groove 11. A movable stop 12 is fixedly connected to the bottom of the movable block 10. The surface of the movable stop 12 slides in contact with the inner wall of the fixed groove 11. By setting the movable stop 12, the annular limiting plate 8 is prevented from being pulled out of the annular groove 7. At the same time, the stability of the annular limiting plate 8 when moving up and down is improved by the movable block 10 and the movable stop 12.

[0022] Furthermore, the annular limiting plate 8 is magnetic, and can be attracted and extracted from the annular groove 7 by a magnet.

[0023] Specifically, loosen the fastening bolt 9, then push the annular limiting plate 8 downward. The annular limiting plate 8 drives the movable stop block 12 to move downward, causing the annular limiting plate 8 and the positioning block 2 to separate. The annular limiting plate 8 moves into the interior of the annular groove 7, and then the positioning block 2 can be pulled out from the positioning groove 3, so that the positioning block 2 and the positioning groove 3 are completely separated. Pull the stator core 1 upward to separate the stator core 1 from the housing mounting plate 100.

[0024] By cooperating with each other, the positioning block 2, positioning groove 3, sliding groove 4, sliding rod 5, slider 6, annular groove 7, annular limiting plate 8, fastening bolt 9, moving block 10, fixed groove 11 and movable stop 12 avoid the need for a large number of bolts to connect and fix the stator core 1 to the housing mounting plate 100, thus avoiding increasing the difficulty of installing the stator core 1 and the housing mounting plate 100 and reducing the efficiency of disassembly and assembly. The stability of the stator core 1 after installation can be guaranteed by limiting several positioning blocks 2 with annular limiting plate 8 and one bolt.

[0025] In use, place the stator core 1 on the top of the housing mounting plate 100 so that the positioning groove 3 corresponds to the position of the positioning block 2. Then push the positioning block 2 so that the positioning block 2 is inserted into the positioning groove 3. Then use the magnet to attract and pull the annular limiting plate 8 out of the annular groove 7. Then tighten the fastening bolt 9 to fix the annular limiting plate 8 to the positioning block 2 located on the left side to complete the installation.

[0026] In summary, the precision axial flux stator for new energy vehicles solves the problems mentioned in the background art through the mutual cooperation of positioning block 2, positioning groove 3, sliding groove 4, sliding rod 5, sliding block 6, annular groove 7, annular limiting plate 8, fastening bolt 9, moving block 10, fixed groove 11 and movable stop 12.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
