Benefits of technology

This patent invention helps to make a stronger connection between an impeller and a bearing in a way that prevents the bearing from becoming deformed. This is done by using a hub that is securely attached to the bearing using a process called cladding. This makes it easier to install and eliminates the need for extra parts.

Problems solved by technology

Therefore, the installation procedure is relatively complex and time consuming.

Embodiment Construction

[0012]With reference to FIGS. 1 and 2, a fan structure 100 in accordance with a first embodiment of the present invention includes a hollow body 110, a fixing pillar 120, a stator 130, a bearing 140, an impeller 150, a circuit board 160 and a carrier 170. The hollow body 110 comprises a bottom plate 111 and a ring wall 112 disposed on the bottom plate 111, wherein the circuit board 160 is disposed around the ring wall 112 of the hollow body 110 and is disposed on the carrier 170. The fixing pillar 120 penetrated through an axial hole 142 of the bearing 140 comprises a first end 121 and a second end 122, and the first end 121 is fixed at the bottom plate 111 of the hollow body 110. The stator 130 is installed at the ring wall 112 and electrically connects with the circuit board 160. The bearing 140 is a preformed bearing. In this embodiment, the bearing 140 is made of plastic, the bearing 140 comprises a plurality of first lodge portions 141, a top terminal 143, a bottom terminal 144...

Abstract

A fan structure includes a bearing and an impeller, wherein the bearing comprises a plurality of first lodge portions, and the impeller comprises a hub and a plurality of blades. The hub comprises a plurality of second lodge portions. The first lodge portions are cladded with the second lodge portions by means of injection molding.

Description

FIELD OF THE INVENTION[0001]The present invention is generally related to a fan structure, which particularly relates to the fan structure with simplified manufacturing process.BACKGROUND OF THE INVENTION[0002]As illustrated in FIG. 7, a conventional fan structure 10 includes a frame body 11, a tube 12, a bearing 13, a stator 14, a rotating shaft 15 and an impeller 16. The tube 12 couples to the frame body 11, the bearing 13 is disposed at the tube 12, the stator 14 couples to the tube 12, and the rotating shaft 15 is penetrated through the bearing 13. The impeller 16 comprises a plurality of blades 16a and a hub 16b coupled to the rotating shaft 15. In this case, the tube 12, the bearing 13, the stator 14, the rotating shaft 15 and the impeller 16 must be installed within the frame body 11 in sequence during the installation process of the fan structure 10. Furthermore, the hub 16b of the impeller 16 is coupled to the rotating shaft 15. Therefore, the installation procedure is rela...
