Description

Technical Field

[0001] This utility model belongs to the field of starter technology, and specifically relates to a plastic brush holder device for commercial vehicle starters. Background Technology

[0002] Previously, commercial vehicle starter brush holders were assembled in reverse, with the brush holder mounting plate not contacting the starter motor rear cover, resulting in poor heat dissipation and reduced starter motor lifespan, requiring further improvement. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a plastic brush holder device for commercial vehicle starters, which can solve the problems existing in the prior art.

[0004] To solve the above problems, the technical solution provided by this utility model is as follows:

[0005] This utility model embodiment provides a commercial vehicle starter plastic brush holder device, including a starter stator (1), four plastic brush boxes (2), a brush holder fixing plate (3), and a starter aluminum rear cover (4). The four plastic brush boxes (2) are arranged in a circumferential array with the center of the starter stator (1) as the center. The brush holder fixing plate (3) is provided at the step on the surface of the four plastic brush boxes (2). The starter aluminum rear cover (4) is attached to the brush holder fixing plate (3) to improve the heat dissipation performance of the brush holder fixing plate (3).

[0006] In an optional embodiment of this utility model, the plastic brush box (2) has an opening structure (2-1) on the side facing the brush holder fixing plate (3), and the opening structure (2-1) is covered by the brush holder fixing plate (3).

[0007] Beneficial Effects: This embodiment of the invention provides a plastic brush holder device for a commercial vehicle starter motor. Four plastic brush boxes are arranged in a circular array around the center of the starter motor stator. Brush holder fixing plates are provided at the stepped areas on the surfaces of the four plastic brush boxes. An aluminum rear cover of the starter motor is attached to the brush holder fixing plate, greatly improving the heat dissipation performance of the brush holder fixing plate. This commercial vehicle starter motor plastic brush holder structure is rationally designed. Because the brush holder fixing plate is attached to the aluminum rear cover of the starter motor, heat dissipation performance is greatly improved, extending the lifespan of the starter motor.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The terms "upper," "lower," "front," "rear," "left," and "right," etc., used when describing the installation position or direction of the structure or components in this embodiment are based on the orientation shown in the accompanying drawings. They are merely for convenience of description, used to distinguish the relative positions of various components or directions, and do not represent the orientation of the plastic brush holder structure in use in this embodiment.

[0015] like Figures 1-5 As shown, this embodiment of the present invention provides a plastic brush holder device for a commercial vehicle starter motor, including a starter motor stator 1, four plastic brush boxes 2, a brush holder fixing plate 3, and a starter motor aluminum rear cover 4. The four plastic brush boxes 2 are arranged in a circumferential array around the center of the starter motor stator 1. The brush holder fixing plate 3 is located at the stepped areas on the surfaces of the four plastic brush boxes 2, and the starter motor aluminum rear cover 4 is attached to the brush holder fixing plate 3. In this embodiment, the brush holder fixing plate 3 is assembled in a forward orientation, allowing it to fit snugly against the starter motor aluminum rear cover 4, greatly improving the heat dissipation performance of the brush holder fixing plate 3. The side of the plastic brush box 2 facing the brush holder fixing plate 3 has an opening structure 2-1, which is covered by the brush holder fixing plate 3.

[0016] The plastic brush holder structure of this commercial vehicle starter has a reasonable design. Because the brush holder fixing plate is attached to the aluminum rear cover of the starter, the heat dissipation performance is greatly improved and the life of the starter is extended.

[0017] Although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
