Description

Technical Field

[0001] The utility model relates to an end cover of a starting motor for an automobile, belonging to the technical field of automobile motor end covers. Background Art

[0002] The generator end cover is generally divided into a front cover and a rear cover, which are cast with aluminum alloy. The rear cover is equipped with a brush assembly, which consists of a brush, a brush holder and a brush spring. The composition of the generator end cover is also determined by the engine fixed generator bracket adapted to the corresponding vehicle model. The generator end cover plays the role of fixing the rotor, stator, rectifier and brush assembly. The generator end cover cast by aluminum alloy can effectively prevent magnetic leakage. Aluminum alloy has good heat dissipation performance. The generator end cover can protect the generator equipment.

[0003] In the prior art, such as the "an end cover for a motor" with Chinese patent number: CN 211151671 U, it includes an end cover body, a metal heat sink is provided on the surface of the end cover body, an integrally formed clamping block is provided at the edges of the metal heat sink, a clamping groove matching the clamping block is provided on the end cover body, the metal heat sink is connected to the clamping groove on the end cover body through the clamping block, a plurality of rows of raised fins are provided on the outer surface of the metal heat sink, a bearing mounting hole is provided in the middle of the end cover body, four screw holes are evenly distributed on the outer side of the end cover body, a screw is installed in the screw hole, a clamping block is provided at the end of the screw, the clamping block is arranged around the bearing mounting hole, a nut connecting the screw is provided on the outside of the end cover body, the outer end of the screw is fixedly connected to the limiting block, a plug cover is provided on the surface of the end cover body at the bearing mounting hole, a through hole is provided in the middle of the plug cover, and a crack connecting the through hole is provided on the surface of the plug cover. The beneficial effect is that it is composed of a metal heat sink and an injection-molded end cover body, which simplifies the motor manufacturing process, can reduce costs, and improve production efficiency. The heat inside the motor is transferred out through the heat sink, which can speed up the heat dissipation. The screw drives the clamping block to move linearly, so that the arc shape formed by multiple clamping blocks for clamping the bearing can be adjusted according to the size of different bearings. When replacing the bearing, it is only necessary to adjust the size of the clamping arc formed by all the clamping blocks. It avoids reprocessing the bearing chamber, and the replacement process is more convenient and quick, reducing the processing cost.

[0004] However, in the prior art, long-term use of a car will cause the generator to generate heat, and failure to provide a good heat dissipation effect will result in unstable vehicle driving or damage to the generator. A general heat dissipation method is to open a heat dissipation port on the motor end cover, but the heat dissipation effect is not obvious and cannot meet the use of the equipment. Therefore, a starter motor end cover for a car is designed. Utility Model Content
