The starter motor plays a crucial role in a car, helping the engine run smoothly during startup and providing convenience for the driver. The carbon brush holder base plate is a key support structure for the starter motor carbon brush assembly, and its main function is to fix the position of the carbon brushes and ensure stable current transmission.

[0003] Prior art 1 (Chinese patent application No. CN202321476598.2, filed on 2023-06-12) discloses a carbon brush holder base plate for an automotive starter motor. During use, it includes a base plate body and a fixing frame. The base plate body is cross-shaped in top view, and multiple fixing frames are symmetrically arranged. One end of each fixing frame is connected to the lower end face of the base plate body via a hinge. By setting fixing components and limiting parts, the carbon brush holder can be easily connected to the starter motor. Through the cooperation of the fixing components and limiting parts, the fixing frame can be released simultaneously during the unlocking of the carbon brush holder, thus eliminating the need to manually remove the carbon brush and completing the disassembly of the carbon brush holder, making disassembly more convenient and faster.

[0004] Although existing technology allows for the installation of carbon brushes, the size of the fixing frame is usually fixed during operation, making it inconvenient to adjust the limit according to the different sizes of the carbon brushes. This is not only inconvenient, but also insufficient in limiting the carbon brushes, causing axial movement of the carbon brushes, resulting in current fluctuations or sparks, and a high wear rate of the carbon brushes. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-6 The present invention provides the following technical solution: an adjustable limit carbon brush holder base plate for an automobile starter, including a base plate body 1, a fixing component 2 fixedly connected to the top surface of the base plate body 1, a sliding component 3 provided on one side of the inner wall of the fixing component 2, a top cover 4 fixedly connected to the top surface of the fixing component 2, and a limiting component 5 provided inside the top cover 4.

[0020] The limiting component 5 includes an adjusting screw 501 installed inside the annular block 401. An adjusting block 502 is fixedly connected to the top end of the adjusting screw 501. A connecting block 504 is rotatably connected to one end of the adjusting screw 501. A second fixing plate 505 is fixedly connected to the bottom surface of the connecting block 504. A second rotating wheel 506 is rotatably connected to the inner wall of the second fixing plate 505. Limiting sliders 507 are provided on both sides of the second fixing plate 505.

[0021] Example 1: As Figure 1 , Figure 2 and Figure 3 The present invention provides the following technical solution: an adjustable limit carbon brush holder base plate for an automotive starter, which discloses a fixing component 2: including a mounting base 201 installed on the top surface of the base plate body 1, a groove 202 is provided on one side of the inner wall of the mounting base 201, and limit grooves 203 are provided on both sides of the inner wall of the mounting base 201. A carbon brush spring mounting rod 204 is fixedly connected to the top side surface of the mounting base 201. The groove 202 is U-shaped, and the size and structure of the limit groove 203 are consistent with the size and structure of the limit slider 507.

[0022] In use, the carbon brush retainer can be fixed on the carbon brush retainer mounting rod 204, with one end of the carbon brush retainer located inside the groove 202. The groove 202 limits the movement of the carbon brush retainer. When the second fixing plate 505 of the limiting component 5 is adjusted, the second fixing plate 505 slides in the limiting slide groove 203 through the limiting slider 507, which limits the movement of the second fixing plate 505.

[0023] Example 2: Figure 1 , Figure 2 , Figure 5 and Figure 6 The technical solution shown, based on Embodiment 1, also discloses a limiting component 5, including an adjusting screw 501 installed inside the annular block 401.

A second rotating wheel 506 is rotatably connected to the inner wall of the second fixing plate 505. Limiting sliders 507 are provided on both sides of the second fixing plate 505.

[0024] In use, the adjusting block 502 can be rotated forward or backward to drive the adjusting screw 501 to rotate, depending on the size of the carbon brush. The anti-slip groove 503 on the outer wall of the adjusting block 502 can increase the friction between the hand and the adjusting block 502, making it easy to rotate. When the adjusting screw 501 rotates, it will be constrained by the threaded groove 402 inside the annular block 401, causing the adjusting screw 501 to move downward or upward. The adjusting screw 501 is rotatably connected to the connecting block 504, causing the connecting block 504 and the second fixing plate 505 to move downward or upward. The second fixing plate 505 slides in the limiting groove 203 through the limiting slider 507. Through the cooperation of the second rotating wheel 506 and the first rotating wheel 302 on the inner wall of the first fixing plate 301 in the sliding assembly 3, the upper and lower ends of the carbon brush can be adjusted and limited, restricting the axial movement of the carbon brush, ensuring constant spring pressure, avoiding current fluctuations or sparks caused by carbon brush shaking, and suppressing uneven wear and breakage, effectively reducing the wear rate of the carbon brush.
