[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0023] like Figures 1-4 As shown, a four-pole dual-control motor brush plate component proposed in an embodiment of the present invention includes a brush plate body 1, the top of the brush plate body 1 is fixedly connected with four fixing boxes 2, a fixing rod 3 is welded on the inner wall of one side of the fixing box 2, and a latch 4 is slidably connected to the fixing rod 3, and a ball 5 is embedded in the end of the latch 4, and a spring 6 is fixedly connected between the other end of the latch 4 and the inner wall of one side of the corresponding fixing box 2, and the spring 6 is movably sleeved on the corresponding fixing rod 3, and an L-shaped rod 7 is welded on the bottom of the latch 4. The end of the L-shaped rod 7 extends to the outside of the corresponding fixing box 2 and is welded with a pull block 8. There are two carbon brush box bodies 9 in movable contact on the brush plate body 1, and L-shaped blocks 10 are welded on both sides of the carbon brush box body 9. One side of the L-shaped block 10 is set as an inclined surface 11, and a card slot 12 is opened on the inclined surface 11. The card slot 12 is clamped with the corresponding card pin 4, and the limiting column 14 on the carbon brush box body 9 is inserted into the corresponding limiting groove 13. At the same time, the carbon brush box body 9 drives the corresponding When the L-shaped block 10 is inserted into the fixing box 2 through the rectangular hole 15, the inclined surface 11 on the L-shaped block 10 contacts and squeezes the corresponding ball 5. Under the action of the squeezing force, the ball 5 moves and rotates, and the ball 5 drives the corresponding latch 4 to slide on the fixing rod 3 and compresses the spring 6. When the slot 12 is aligned with the corresponding latch 4, the spring 6 in the compressed state is reset. Under the action of the spring 6's own elastic force, the spring 6 drives the latch 4 to be engaged with the corresponding slot 12, thereby fixing the carbon brush box body 9. When disassembling, the two pulling blocks 8 on the same side are pulled away from each other. The pulling block 8 drives the corresponding latch 4 through the L-shaped rod 7, and the latch 4 slides on the corresponding fixing rod 3, so that the latch 4 is separated from the corresponding slot 12. Then the carbon brush box body 9 is moved upward, and the carbon brush box body 9 drives the corresponding L-shaped block 10 to separate from the fixing box 2, thereby removing the carbon brush box body 9. The disassembly and assembly are simple and do not require the use of professional tools.

[0024] In some embodiments, the balls 5 cooperate with corresponding inclined surfaces 11 .

The top of the limiting column 14 is fixedly connected to the bottom of the corresponding carbon brush box body 9. The setting of the limiting column 14 plays a limiting role.

[0026] In some embodiments, a rectangular hole 15 is formed on the inner wall of the top of the fixed box 2, and the inner wall of the rectangular hole 15 is in movable contact with the outer side of the corresponding L-shaped block 10.

[0027] In some embodiments, a guide hole is formed on the inner wall of one side of the fixed box 2, and the fixed box 2 is connected with the corresponding L-shaped rod 7 through the guide hole. The L-shaped rod 7 is arranged to play a connecting role.

[0028] In some embodiments, a limiting hole is formed on the catch 4, and the catch 4 is connected with the corresponding fixed rod 3 through the limiting hole. The fixed rod 3 is arranged to play a positioning role.

[0029] When in use, the carbon brush box body 9 and the brush plate body 1 are in a separated state at this time. When installing, the limiting column 14 on the carbon brush box body 9 is inserted into the corresponding limiting groove 13, and at the same time, the carbon brush box body 9 drives the corresponding L-shaped block 10 to be inserted into the fixed box 2 through the rectangular hole 15. The inclined surface 11 on the L-shaped block 10 is in contact with and pressed against the corresponding ball 5. Under the action of the pressing force, the ball 5 moves and rotates. The ball 5 drives the corresponding catch 4 to slide on the fixed rod 3 and compresses the spring 6. When the catch slot 12 is matched with the corresponding catch 4, the spring 6 in the compressed state resets under the action of the spring force of the spring 6. The spring 6 drives the catch 4 to be matched with the corresponding catch slot 12, so as to fix the carbon brush box body 9. When disassembling, the two pull blocks 8 on the same side are pulled away from each other. The pull block 8 drives the corresponding catch 4 through the L-shaped rod 7. The catch 4 slides on the corresponding fixed rod 3, so that the catch 4 is separated from the corresponding catch slot 12. Then, the carbon brush box body 9 is moved upward. The carbon brush box body 9 drives the corresponding L-shaped block 10 to be separated from the fixed box 2, so as to take down the carbon brush box body 9. The disassembly and assembly are simple and do not need to use professional tools.
