[0015] Beneficial technical effects of the present invention: According to the new energy vehicle drive motor rotor structure of the present invention, a permanent magnet is slidably installed inside the motor rotor housing. Rotating the sleeve causes the rotating block to slide in the rotating groove, thereby driving the second connecting block to rotate. When the second connecting block rotates, it drives the connecting column to move, and when the connecting column moves, it drives the auxiliary extrusion block to move. When the auxiliary extrusion block contacts the main extrusion block, the auxiliary extrusion block continues to move and extrudes the main extrusion block. At this time, the second spring shortens, and the slip ring slides on the sliding rod, thereby driving the support column and positioning plate to move, inserting the positioning block into the slot. This facilitates the limiting of the installed permanent magnet, eliminating the need for glue to install the permanent magnet, making installation more convenient. Furthermore, when the permanent magnet is damaged, it can be disassembled and replaced. Rotating the sleeve causes the rotating block to slide in the rotating groove, thereby driving the second connecting block to rotate. When the second connecting block rotates, it drives the connecting column to move, and when the connecting column moves, it drives the auxiliary extrusion block to move. When the auxiliary extrusion block separates from the main extrusion block, the second spring extends, driving the main extrusion block to move, sliding the positioning block out of the slot, and pulling to remove the permanent magnet, facilitating the disassembly and replacement of the permanent magnet.
[0016] By setting the insert block and releasing the moving plate, the first spring extends, causing the guide ring to slide on the guide rod, which in turn moves the insert block. At this point, the insert block can be inserted into the positioning groove on the rotating block, which facilitates the limiting of the rotated sleeve, and thus facilitates the limiting of the installed permanent magnet.

At this time, the second spring 84 shortens, and the slip ring 81 slides on the slide rod 8, thereby driving the support column 91 and the positioning plate 9 to move and insert the positioning block 92 into the slot 21. This facilitates the limiting of the installed permanent magnet 2. There is no need to use glue to install the permanent magnet 2, making the installation more convenient. Moreover, when the permanent magnet 2 is damaged, the damaged permanent magnet 2 can be disassembled and replaced. The support assembly includes a support rod 3, a support frame 31, a side block 32, and a bottom block 33. The support rod 3 is installed on the first connecting block 11, and the side block 32 is installed on the support rod 3.

Multiple second connecting blocks 51 are installed on the sleeve 5. The rotating block 52 is installed on the sleeve 5. The support frame 31 has a rotating groove that cooperates with the rotating block 52. By setting the rotating block 52 to rotate in the rotating groove, the sleeve 5 can be easily rotated to drive the auxiliary extrusion block 41 to rotate. The sliding component includes a slide rod 8, a slip ring 81, a third connecting block 82, a side column 83 and a second spring 84. The slide rod 8 is installed on the first connecting block 11, and the slip ring 81 is slidably installed on the slide rod 8. A third connecting block 82 is mounted on ring 81, and a side post 83 is mounted on the third connecting block 82. The slip ring 81 is connected to the first connecting block 11 via a second spring 84. By setting the slip ring 81 to slide on the sliding rod 8, the main extrusion block 4 can be easily guided and limited. The side post 83 facilitates support for the main extrusion block 4. The extrusion assembly includes a main extrusion block 4, an auxiliary extrusion block 41, and a connecting post 42. The main extrusion block 4 is mounted on the side post 83, and the connecting post 42 is mounted on the second connecting block 51. One end of the connecting post 42 is equipped with the auxiliary extrusion block 41. The connecting post 42 facilitates support for the auxiliary extrusion block 41.

By setting the support column 91, the positioning block 92 can be easily supported. The permanent magnet assembly includes a permanent magnet 2, a slot 21, and a mounting groove 22. The motor rotor housing 1 has a mounting groove 22, and the permanent magnet 2 is slidably installed inside the mounting groove 22. Both the motor rotor housing 1 and the permanent magnet 2 have A slot 21 is provided to cooperate with the positioning block 92. Rotating the sleeve 5 causes the rotating block 52 to slide in the slot, thereby driving the second connecting block 51 to rotate. When the second connecting block 51 rotates, it drives the connecting post 42 to move. The moving connecting post 42 then drives the auxiliary pressing block 41 to move. When the auxiliary pressing block 41 separates from the main pressing block 4, the second spring 84 extends, driving the main pressing block 4 to move, thus sliding the positioning block 92 out of the slot 21 and allowing the permanent magnet 2 to be easily removed and replaced.
[0021] In this embodiment, as Figure 1 and Figure 10 As shown, the reset assembly includes a first spring 7, a guide ring 71, a guide rod 72, and a support block 73. The guide rod 72 is mounted on the first connecting block 11, and the guide ring 71 is slidably mounted on the guide rod 72. The guide ring 71 is connected to the first connecting block 11 via the first spring 7. The support block 73 is mounted on the guide ring 71.

By providing the insert block 61, the movable plate 6 is released, the first spring 7 extends, and drives the guide ring 71 to slide on the guide rod 72, which can drive the insert block 61 to move. At this time, the insert block 61 can be inserted into the positioning groove on the rotating block 52, which can facilitate the limiting of the rotated sleeve 5, and thus facilitate the limiting of the installed permanent magnet 2.
[0022] In this embodiment, as Figures 1-11 As shown in the figure, the working process of a new energy vehicle drive motor rotor structure provided in this embodiment is as follows: Step 1: Slide the permanent magnet 2 inside the motor rotor housing 1, rotate the sleeve 5, and the rotating block 52 slides in the rotating groove, thereby driving the second connecting block 51 to rotate. When the second connecting block 51 rotates, it drives the connecting column 42 to move. When the connecting column 42 moves, it drives the auxiliary extrusion block 41 to move. When the auxiliary extrusion block 41 contacts the main extrusion block 4, the auxiliary extrusion block 41 continues to move and extrudes the main extrusion block 4. At this time, the second spring 84 shortens, the slip ring 81 slides on the slide rod 8, thereby driving the support column 91 and the positioning plate 9 to move, inserting the positioning block 92 into the slot 21 to limit the permanent magnet 2 after installation.

[0023] In summary, in this embodiment, according to the rotor structure of the new energy vehicle drive motor, the permanent magnet 2 is slidably installed inside the motor rotor housing 1. Rotating the sleeve 5 causes the rotating block 52 to slide in the rotating groove, thereby driving the second connecting block 51 to rotate. When the second connecting block 51 rotates, it drives the connecting column 42 to move. When the connecting column 42 moves, it drives the auxiliary extrusion block 41 to move. When the auxiliary extrusion block 41 contacts the main extrusion block 4, the auxiliary extrusion block 41 continues to move, thereby extruding the main extrusion block 4. At this time, the second spring 84 shortens, and the slip ring 81 slides on the sliding rod 8, thereby driving the support column 91 and the positioning plate 9 to move, thus moving the positioning block 9... Inserting the sleeve 2 into the slot 21 facilitates the positioning of the installed permanent magnet 2, eliminating the need for glue and making installation convenient. Furthermore, if the permanent magnet 2 is damaged, it can be easily removed and replaced. The support rod 3 and support frame 31 work together to support the sleeve 5. The rotating block 52, rotatably connected to the rotating groove, allows the sleeve 5 to rotate, driving the auxiliary extrusion block 41. The sliding ring 81, slidably connected to the sliding rod 8, guides and limits the main extrusion block 4. The side column 83 provides support for the main extrusion block 4. The connecting column 42... The system facilitates support for the auxiliary compression block 41. The positioning block 92, in conjunction with the slot 21, facilitates the positioning of the installed permanent magnet 2. The support column 91 supports the positioning block 92. The guide ring 71, slidably connected to the guide rod 72, facilitates the guiding and limiting of the moving plate 6. The support block 73 supports the moving plate 6. The pull groove 62 facilitates pulling the moving plate 6. The insertion block 61 releases the moving plate 6, causing the first spring 7 to extend, sliding the guide ring 71 on the guide rod 72, and thus moving the insertion block 61. When the sleeve 5 is rotated, the insert 61 can be inserted into the positioning groove on the rotating block 52, which facilitates the limiting of the rotated sleeve 5 and the permanent magnet 2 after installation. When the sleeve 5 is rotated, the rotating block 52 slides in the rotating groove, thereby driving the second connecting block 51 to rotate. When the second connecting block 51 rotates, it drives the connecting column 42 to move. When the connecting column 42 moves, it drives the auxiliary extrusion block 41 to move. When the auxiliary extrusion block 41 separates from the main extrusion block 4, the second spring 84 extends, driving the main extrusion block 4 to move and slide the positioning block 92 out of the slot 21, pulling and disassembling the permanent magnet 2, which facilitates the disassembly and replacement of the permanent magnet 2.
