[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 4 As shown, a starter carbon brush mounting structure comprises a plurality of carbon brush boxes 2, which are cleverly mounted on a modular mounting base 1. The modular mounting base 1 is composed of a plurality of fan-shaped seats 11 and recessed grooves 12. Specifically, six carbon brush boxes 2 are respectively mounted on six fan-shaped seats 11, and there is a one-to-one correspondence between them. These fan-shaped seats 11 are designed to be a circular ring structure, and the side walls of each fan-shaped seat 11 are provided with a recessed groove 12 for easy installation and fixation. In addition, a first arc-shaped through groove 13 is provided on the end face of each fan-shaped seat 11 for easy installation and disassembly. In order to further enhance the stability and firmness of the structure, an arc-shaped connecting cover 14 is also provided on the inner wall of the fan-shaped seat 11.

[0025] The fastening docking seat 3 is another key component, comprising a fixing sleeve 31 and a top plate 32. The arcuate connecting covers 14 of the six sector-shaped seat bodies 11 together form a circular connecting cover. The fixing sleeve 31 is connected to the corresponding position of the circular connecting cover, and the upper end of the fixing sleeve 31 is a top plate 32. The end surface of the top plate 32 is provided with a second arcuate through groove 33 that adapts to the first arcuate through groove 13. By inserting bolts, anti-slip washers, and nuts into the two arcuate through grooves, the sector-shaped seat body 11 and the top plate 32 can be firmly fixed, thereby greatly enhancing the stability between the sector-shaped seat body 11 and the top plate 32.

[0026] To further enhance installation flexibility and reliability, rubber strips are installed at the joints of each sector-shaped base 11 to absorb vibration and shock. The sector-shaped base 11 and recessed slot 12 are integrated into one design, with circular holes at the bottom of the recessed slot 12 serving as mounting holes. A bracket, designed with an Ω-shaped cross-section, is mounted on the outside of the brush box 2 to provide sufficient strength and stability. The bracket is bolted to the sector-shaped base 11, while rubber gaskets are placed between the brush box 2, the bracket, and the sector-shaped base 11 to further reduce vibration and noise.

[0027] The first arcuate slot 13 has a C-shaped cross-section, with semicircular ends, ensuring perfect alignment and size with the second arcuate slot 33. This design is not only aesthetically pleasing but also ensures precise and reliable installation. The outer wall of the arcuate connecting cover 14 is threaded, while the inner wall of the fixing sleeve 31 features matching threads. This threaded connection securely connects the fixing sleeve 31 to the top plate 32. The cross-sections of the fixing sleeve 31 and top plate 32 are T-shaped, which not only aesthetically pleasing but also enhances the stability of the overall structure.

[0028] To further enhance the stability and durability of the top plate 32, a rubber ring is attached to its upper end surface via adhesive. The top plate 32's primary function is to support the six sector-shaped mounting bodies 11, ensuring stable operation of the entire starter carbon brush mounting structure. This meticulously designed structure ensures efficient and stable starter performance in a variety of operating environments.

[0029] Installation process: Make sure that the fan-shaped seat body 11 and the recessed groove 12 of the modular mounting base 1 are intact. Prepare six carbon brush boxes 2 and make sure they are in good condition. Put the outer bracket of each carbon brush box 2 on the corresponding fan-shaped seat body 11. Use rubber gaskets to fix the carbon brush box 2 to the bracket and the fan-shaped seat body 11 to reduce vibration and noise. Fix the bracket to the fan-shaped seat body 11 with bolts. Combine the arc-shaped connecting covers 14 of the six fan-shaped seat bodies 11 into a circular connecting cover. Connect the fixing sleeve 31 at the corresponding position of the circular connecting cover. Connect the top plate 32 to the upper end of the fixing sleeve 31, and ensure that the end face of the top plate 32 is provided with a second arc-shaped groove 33 that is compatible with the first arc-shaped groove 13. Insert bolts, anti-slip gaskets and nuts into the first arc-shaped groove 13 and the second arc-shaped groove 33. Ensure that the fan-shaped seat body 11 is firmly fixed to the top plate 32 by tightening with bolts. Install rubber strips at the connection of each fan-shaped seat body 11 to absorb vibration and impact. Check all connections for tightness and ensure there are no loose parts. Verify that all components are installed correctly and that nothing is missing. Perform a preliminary test to ensure the starter carbon brush mounting structure is functioning properly.
