Description

Technical Field

[0001] The utility model relates to the technical field of generator covers, in particular to an automobile generator cover. Background Art

[0002] Automobiles are equipped with generators for providing power for on-board electronic devices. The generator includes a stator and a rotor. The rotor shaft is connected to the output shaft of the engine through a transmission mechanism to convert mechanical energy into electrical energy. The stator and the rotor are both arranged in a generator housing. In order to facilitate heat dissipation, a fan blade is arranged on the rotor shaft. The fan blade rotates with the rotor, sucking air from one end of the generator housing, passing through the stator and the rotor, and then sending air out from the other end of the generator housing, i.e., the air outlet in the cover, thereby achieving heat dissipation of the generator. However, the current generator cover cannot be docked with the rotor shaft. Therefore, as the fan blade rotates for a long time, the stability of the rotor shaft will deteriorate. Therefore, it is necessary to provide a generator cover that can support the rotor shaft on which the fan blade is installed. Utility Model Content

[0003] In view of the problems existing in the existing automobile generator cover, the utility model is proposed.

[0004] Therefore, the purpose of the utility model is to provide a car generator cover, which solves the problem that the current generator cover cannot be docked with the rotor shaft. As the fan blades rotate for a long time, the stability of the rotor shaft will deteriorate. Therefore, it is necessary to provide a generator cover that can support the rotor shaft on which the fan blades are installed.

[0005] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0006] An automobile generator cover comprises a generator cover body, wherein a first through hole is formed in the generator cover body, and a support seat is installed at the center of the generator cover body;

[0007] A second through hole is opened at the center of the support seat. When the generator cover body is installed, the second through hole is butted against the rotor shaft through the bearing.

[0008] As a preferred solution of the automobile generator cover described in the utility model, a groove is provided on the generator cover body, a first air vent is provided on the bottom wall of the groove, and a second air vent is provided on the side wall of the groove.

[0009] As a preferred solution of the automobile generator cover described in the utility model, a mounting hole is provided on the generator cover body.

[0010] As a preferred solution of an automobile generator cover described in the utility model, a first internal threaded hole is provided on the generator cover body, a second internal threaded hole with the same aperture as the first internal threaded hole is provided on the support seat, and the support seat and the generator cover body are fixed by bolts.

[0011] As a preferred solution of the automobile generator cover described in the utility model, wherein: a protrusion is integrally provided on the edge wall of the generator cover body, and the mounting hole is located on the protrusion.

[0012] Compared with existing technologies:

[0013] By opening a through hole in the center of the generator cover body and installing a support seat in the center of the generator cover body, the support seat is connected to the rotor shaft through a bearing, so that the rotor shaft can be rotatably supported, thereby ensuring the stability of the rotor shaft rotation.
