Insert-type positioning assembly design for motor interior

Abstract

The present invention provides an insert-type positioning assembly design for the interior of a motor housing. It includes: a motor housing, in which a motor assembly is installed, such as a stator made of silicon steel sheets, a reduction mechanism, and the like. The motor housing is configured with a cylindrical shape, and at least one outward rib or groove is provided along the axial direction of the inner wall to serve as a fixing part. On the outer edge of the outer gear seat of the stator made of silicon steel sheets and the reduction mechanism, a corresponding assembly part is provided to facilitate the assembly within the motor housing. The assembly part and the fixing part are configured as corresponding ribs or grooves, allowing the motor assembly to be directly inserted into the motor housing by aligning the assembly part with the axial fixing part. With this invention, it is simple to manufacture, with low production costs, and can be directly extruded or injection molded. There is no need to drill holes in the motor housing to secure screws, providing excellent strength and waterproof performance. This invention makes the assembly of the motor components with the motor housing easier, allowing for precise axial insertion to achieve accurate positioning. Additionally, the motor stator and the motor housing can be assembled more tightly, further improving the overall heat dissipation efficiency of the motor.
