Fan base and manufacturing method thereof

Abstract

A fan base comprises a metal baseplate and a plastic bearing column formed on the metal baseplate. A plurality of bent pieces are formed on the metal baseplate, each bent piece is bent upwards from the metal baseplate, the plastic bearing column is formed on the metal baseplate by means of injection molding, the metal baseplate is attached to the bottom surface of the plastic bearing column, and the bent pieces are embedded in the plastic bearing column. Compared with a plastic bearing seat bottom wall, the bottom wall, composed of the metal baseplate, of the plastic bearing column is higher in strength, thinner and capable of meeting the requirement on thinning. The invention further provides a manufacturing method of the fan base.

Description

technical field [0001] The invention relates to a fan base and a manufacturing method thereof. Background technique [0002] A traditional fan seat includes a bottom plate and a bearing seat formed on the bottom plate, wherein the bearing seat includes a cylindrical side wall and a bottom wall. see figure 1 , in the prior art, the bottom plate 100 and the bearing seat 200 are generally integrally formed by plastic, but the integrally formed structure of plastic is used. Due to the limitation of the thickness of the plastic, the formed bottom plate 100 and the bearing seat 200 are thicker, which is difficult to Meet the requirements of thinning. see figure 2 , in the prior art, there is also a structure in which the bottom plate 100 of metal material is combined with the bearing seat 200 of plastic material. This structure is that the bearing seat 200 of plastic material is injection-molded on the bottom plate 100 of metal material, but The material of the bottom wall 21...

AI Technical Summary

Problems solved by technology

see figure 1 , in the prior art, the bottom plate 100 and the bearing seat 200 are generally integrally formed by plastic, but the integrally formed structure of plastic is used. Due to the limitation of the thickness of the plastic, the formed bottom plate 100 and the bearing seat 200 are thicker, which is difficult to Meet the requirements of thinning

see figure 2 , in the prior art, there is also a structure in which the bottom plate 100 of metal material is combined with the bearing seat 200 of plastic material. This structure is that the bearing seat 200 of plastic material is injection molded on the bottom plate 100 of metal material, but The bottom wall 210 of the bearing seat 200 of the material also has restrictions on the thickness of the molding, and it is difficult to meet the requirements of thinning the bearing seat 200

see image 3 , in the prior art, there is also a structure of riveting the bottom plate 100 of metal material and the bearing seat 200 of metal material, but this will increase a riveting process, thereby increasing the production cost of the fan seat
