Technical Field
[0001] The utility model relates to the technical field of automobile generators, in particular to a pole claw of an automobile generator. Background Art
[0002] The car generator is the main power source for the car's electrical equipment. It not only provides power for the ignition system and other electrical equipment, but also needs to recharge the car battery. The claw pole plays a magnetic role and is an important part of the car's AC generator.
[0003] With the development of the automobile industry, the power requirements for automobile generators are gradually increasing, but the space reserved for automobile generators is constantly being compressed, that is, the claw poles of automobile generators need to provide greater power within a limited space. However, it is difficult to take into account the heat dissipation of the claw poles while maintaining high power, making it difficult for the claw poles to maintain high loads for a long time. At the same time, due to the imperfect design of the claw pole air duct of the motor structure, it is easy to cause aerodynamic noise during operation, reducing the comfort performance of the entire vehicle.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
[0005] In view of the problems in the related technology, the purpose of the utility model is to provide a pole claw of an automobile generator to overcome the above technical problems existing in the existing related technology.

[0007] A pole claw of an automobile generator comprises: a claw pole seat and a plurality of claw feet, wherein the claw feet are rotating bodies, and the claw pole seat and the claw feet are integrally formed, wherein;
[0008] The diameter of the transverse section of the claw foot gradually decreases from bottom to top, the end face of the claw foot is a plane, the inner side of the claw foot is an inclined structure, and the outer side of the claw foot is provided with a convex portion.
[0009] Furthermore, an iron core is provided in the claw pole seat, and an axial hole is provided in the iron core.
[0010] Furthermore, a plurality of the claw feet are arranged in a circular shape and at equal intervals on one side of the iron core.
[0011] Furthermore, the inclination angle of the claw foot toward the inner side is 45° to 60°.
[0012] Furthermore, the convex portion is an arc-shaped convex strip structure.
[0013] Beneficial effects of the utility model:
[0014] The utility model adopts a flat end face of the claw foot and an inclined structural design on the inner side of the claw foot, which not only ensures the power generation power but also effectively reduces noise. In addition, the convex portion design on the outer side of the claw foot increases the surface area of the claw foot and the heat dissipation area while ensuring the reliability of the power generation power, thereby improving the heat dissipation effect of the pole claw and thus improving the comfort and safety of the entire vehicle.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0022] According to an embodiment of the utility model, a pole claw of an automobile generator is provided.
[0023] like Figure 1 As shown, a pole claw of an automobile generator comprises: a claw pole seat 1 and a plurality of claw feet 2, wherein the plurality of claw feet 2 are rotating bodies, and the claw pole seat 1 and the plurality of claw feet 2 are integrally formed, wherein;

[0028] In the present technical solution, specifically, the inclination angle of the claw foot 2 toward the inner side surface is preferably 45°.
[0029] Specifically, in application, the tilt angle is preferably 45°, which reduces the collision and friction surface with the air during rotation, and effectively reduces the noise generated by the pole claw during the rotation process.
