[0028] Please see Figure 1-7As shown, a protective assembled motor structure includes: a motor bracket 1, a motor assembly 6, a carbon brush box 3, and a baffle 5. The side wall of the motor bracket 1 is fitted with rivets 9 to limit the carbon brush box 3, and one end of the carbon brush box 3 is inserted into the side wall of the motor bracket 1. The baffle 5 is movably sleeved on the outside of the carbon brush box 3 through a snap-fit ​​assembly and is located on the inside of the motor bracket 1. The snap-fit ​​assembly includes a snap-fit ​​spring 14, a snap-fit ​​post 15, a positioning protrusion 16, and a fixing adhesive 17. The inside of the baffle 5 has a snap-fit ​​groove and an adhesive groove. The outside of the carbon brush box 3 has an adhesive application groove, a positioning groove, and a snap-fit ​​hole. The snap-fit ​​post 15 and the snap-fit ​​spring 14 are both movably installed inside the snap-fit ​​groove. One end of the positioning protrusion 16 is snapped with the snap-fit ​​spring 14, and the other end of the snap-fit ​​post 15 is snapped with the snap-fit ​​hole. The fixing adhesive 17 is applied inside the adhesive application groove and the adhesive groove. The positioning protrusion 16 is inserted into the positioning groove for limitation.

[0029] Specifically, by setting up a baffle 5 and a snap-fit ​​assembly, during use, the baffle 5 is sleeved onto the outside of the carbon brush box 3 through the snap-fit ​​assembly. The baffle 5 is made of insulating material, so the carbon powder after the carbon brush wears can be adsorbed on the baffle 5, avoiding direct contact between the carbon powder and the bracket body. This effectively prevents leakage caused by carbon powder adsorbing on the carbon brush box 3 and the bracket surface after carbon brush wear, providing good protection, ensuring the safe operation of the motor, and allowing the motor to be used continuously for a long time, avoiding economic losses. At the same time, the snap-fit ​​assembly, through the action of the snap-fit ​​spring 14, allows the snap-fit ​​post 15 to extend and retract flexibly, and the positioning protrusion 16 limits the connection between the baffle 5 and the carbon brush box 3. The fixing adhesive 17 applied inside the glue application groove and the adhesive groove further enhances the fixing effect between the baffle 5 and the carbon brush box 3. The positioning protrusion 16 is embedded in the positioning groove, ensuring the stability and reliability of the baffle 5 during operation.

[0030] In this embodiment, the bottom of the motor bracket 1 is threaded with a connecting bolt that is threaded to the motor assembly 6. The bottom wall of the motor bracket 1 has a countersunk threaded hole 8, and the connecting bolt is inserted into the countersunk threaded hole 8. The bottom of the motor bracket 1 is provided with a positioning post, and the positioning post is inserted into the motor assembly 6.

[0031] Specifically, in use, the motors are positioned and installed on the top of the motor assembly 6 using positioning pins, and the motor bracket 1 and the motor assembly 6 are fixed and limited by connecting bolts, which improves the accuracy and stability of the motor bracket 1 installation. The carbon brush is used on the commutator 7 or slip ring of the motor as a sliding contact body for conducting and introducing current. Its structural principle is existing technology.

[0032] A rotating shaft 2 is fixedly installed at the output end of the motor bracket 1. A commutator 7 is fixedly sleeved on the outside of the rotating shaft 2. A mounting groove 10 is opened inside the carbon brush box 3. A carbon brush body 11 is inserted into the mounting groove 10 and contacts the commutator 7. A insertion groove 13 is opened inside the side wall of the carbon brush box 3. A limit bracket 4 is inserted into the insertion groove 13 and limits the insertion. A limit component 12 is provided inside the mounting groove 10. One end of the limit component 12 is engaged with the carbon brush box 3, and the other end of the limit component 12 is engaged with the limit bracket 4. The limit component 12 includes a circular plate, an insertion limit post, and a limit spring. The circular plate is movably inserted into the inside of the mounting groove 10 and engaged with the limit bracket 4. One end of the insertion limit post contacts the carbon brush body 11, and one end of the limit spring is engaged with the circular plate. The other end of the limit spring is movably sleeved on the outside of the insertion limit post, and the two are engaged.

[0033] Specifically, the cooperation between the rotating shaft 2 and the commutator 7 enables the motor to achieve smooth rotation and stable current transmission, allowing the motor to operate efficiently. The limiting component 12 ensures that the carbon brush body 11 is fixed in the mounting groove 10, preventing it from moving during motor operation and thus maintaining good electrical contact. The limiting component 12 is used to fix the limiting bracket 4 and the carbon brush body 11, ensuring that the carbon brush body 11 is correctly positioned in the mounting groove 10 and preventing loosening due to vibration or contact. When the carbon brush body 11 wears, the limiting spring can automatically adjust the contact pressure to ensure the normal operation of the motor.

[0034] In summary, compared with existing technologies, this motor structure has at least the following beneficial effects: By setting up a baffle 5 and a snap-fit ​​assembly, during use, the baffle 5 is fitted onto the outside of the carbon brush box 3 through the snap-fit ​​assembly. The baffle 5 is made of insulating material, so the carbon powder after the carbon brush wears can be adsorbed on the baffle 5, avoiding direct contact between the carbon powder and the bracket body. This effectively prevents leakage caused by carbon powder adsorbing on the carbon brush box 3 and the bracket surface after carbon brush wear, providing good protection, ensuring the safe operation of the motor, and allowing the motor to be used continuously for a long time, avoiding economic losses. At the same time, the snap-fit ​​assembly, through the action of the snap-fit ​​spring 14, allows the snap-fit ​​post 15 to extend and retract flexibly, and the positioning protrusion 16 limits the connection between the baffle 5 and the carbon brush box 3. The fixing adhesive 17 applied inside the glue application groove and the adhesive groove further enhances the fixing effect between the baffle 5 and the carbon brush box 3. The positioning protrusion 16 is embedded in the positioning groove, ensuring the stability and reliability of the baffle 5 during operation.
