Electrical seat

Abstract

The invention provides an electrical seat, which is an integral structural part with the structural characteristics of a rear end cover and a brush basin of a motor. A plurality of groups of inner mounting supports, a plurality of outer mounting supports and a bearing chamber are arranged on the inner lateral surface of the electrical seat. Each inner mounting support comprises two cylinders which are arranged at an interval. The structures of the two cylinders are symmetrical and the same. A groove is formed on each cylinder, and the trend of the groove is parallel to the diameter of the electrical seat. A platform is arranged on the inner side of each cylinder adjacent to the edge of a corresponding groove. An undercut is arranged on the inner side of each cylinder adjacent to the edge of a corresponding platform. The groove, the platform and the undercut are sequentially and adjacently arranged. The planes of the platforms are flush with the bottom surfaces of the grooves. The undercuts are higher than the platforms. An interval for accommodating a sliding rail is formed between each undercut and a corresponding platform. The groove, the platform and the undercut are form an 'L'-shaped mounting position for positioning the inner end of the sliding rail. The electrical seat has the advantages of a few parts, material saving, low noise and high reliability.

Description

technical field [0001] The invention relates to a motor component, in particular to an electric seat. Background technique [0002] The electrical seat of a general motor includes a rear end cover and a brush basin. The rear end cover is generally made of metal material and installed separately. The brush basin is generally made of plastic and / or metal material and installed separately. Since such an electrical seat is composed of two different parts, it needs to be molded separately during production; it needs to be installed separately during installation, which is time-consuming, laborious and costly; and it takes up more motor axial dimensions and space, hindering the miniaturization and thinning of the motor. In addition, since the rear end cover made separately is usually made of metal material, it is heavy, which not only consumes the metal material, but also increases the weight of the motor. Contents of the invention [0003] The object of the present invention ...

AI Technical Summary

Problems solved by technology

Since such an electric seat is composed of two different parts, it needs to be molded separately during production; it needs to be installed separately during installation, which is time-consuming, laborious and costly; moreover, it takes up more motor axial size and Space hinders miniaturization and thinning of motors

In addition, since the rear end cover made separately is usually made of metal material, the weight is relatively heavy, which not only consumes the metal material, but also increases the weight of the motor.
