Description

Technical Field

[0001] This utility model relates to the field of brush installation technology, and in particular to a brush structure that prevents the connection part from falling off. Background Technology

[0002] In actual use, if the gap between the brush and the brush holder is too small, the brush will heat up during operation, and moisture will accumulate between the brush and the brush holder. Over time, rust will form between the brush and the brush holder, causing the brush spring to be unable to press the brush down, resulting in the brush getting stuck in the brush holder, poor contact between the brush and the commutator, and starter motor failure. Current solutions involve improving the corrosion resistance of the brush holder: zinc-nickel alloy plating or copper plating, but the results are not ideal; using stainless steel brush holders is too expensive.

[0003] A starter brush holder structure is proposed in patent CN216649400U. This patent includes a brush holder, brushes, brush holders, a gap drainage section, a water guide groove, a drainage channel, a brush spring, a commutator, a stator, a rotor, a first drainage column, and a second drainage column. The gap drainage section 4 consists of several drainage channels 7 formed on the inner wall of the brush holder 3. The drainage channels 7 are integrally formed with the brush holder 3 and are located on the inner wall of the brush holder 3. The drainage channels 7 on the brush holder 3 can prevent moisture and rust on the brush holder 3 and the brush 2 through the drainage channels 7. The internal structure is simple and can ensure the normal use of the brush 2. The drainage channels 7 include: a first drainage channel 701 and a second drainage channel 702. The second drainage channel 702 is located at the upper and lower ends of the inner wall of the brush holder 3, and the first drainage channel 701 is located between the second drainage channels 702. The drainage channel 701 allows water to pass through the brush holder 3 and the brush 2 through the drainage channels 702. The first drainage groove 701 and the second drainage groove 802 ensure the limiting effect of the brush holder 3 on the brush 2, ensuring a more reasonable internal structure. A first drainage column 1201 is formed between the first drainage groove 701 and the second drainage groove 702, and a second drainage column 1202 is formed between the first drainage groove 701. This allows for better drainage of water vapor generated by the brush 2 through the drainage grooves 701, thereby preventing internal corrosion and ensuring the normal use of the brush 2. By setting drainage grooves and drainage columns on the brush holder, it effectively prevents the brush and brush holder from rusting due to water vapor generated during operation over a long period of time, reducing the formation of large-area corrosion and effectively preventing the brush from jamming due to corrosion. This effectively extends the service life of the brush and ensures the normal use of the brush structure. However, the following problems still exist in this patent:

[0004] Existing brushes lack a good connection structure, which cannot ensure the stability of brush operation and makes installation and disassembly inconvenient.

[0005] To address the above problems, a brush structure that prevents the connection from detaching needs to be designed to overcome these issues. Utility Model Content
