Embodiment
Hereinafter with reference to relevant drawings, illustrate according to a kind of magnet module of present pre-ferred embodiments and a fan, its
Middle identical element will be illustrated with identical reference marks.
Magnet module illustrated in the present invention can be applied to centrifugal fan or aerofoil fan according to different demands, though this theory
Bright book only illustrates aerofoil fan, but the usual technical staff of this area should be appreciated that and this design is applied into centrifugal fan.Letter
Yan Zhi, fan of the present invention will not be implemented to stand as limitation with this.
First, it please refer to the first embodiment schematic diagram of Fig. 1 and Fig. 2, Fig. 1 for magnet module of the present invention.Fig. 2 is Fig. 1
Exploded perspective view.
The present invention is a kind of magnet module 1, including sintered magnet 12, magnetic conduction casing 14 and fixture 16.
Sintered magnet 12 is arranged in magnetic conduction casing 14.And during actual assembled, it is only necessary to which sintered magnet 12 is arranged in into magnetic conduction
The inner ring surface side of housing 14, it is not necessary to additionally attach sintered magnet in a manner of gluing and is fixed on inner ring surface.And can be clear from Fig. 2
Chu understands that the shape of magnetic conduction casing 14 can coordinate sintered magnet 12 to design.Sintered magnet 12 is, for example, iron oxide magnet (ferric
oxide magnet)。
Fixture 16 has multiple buckle units 162, and multiple buckle units 162 can form buckle cell body or buckle is empty
Between, fix multiple buckle units 162 of magnetic conduction casing 14 and the fixture 16 of sintered magnet 12.In other words, buckle list is passed through
The buckle cell body of member 162 or buckle space may be such that magnetic conduction casing 14 is fixed on relative position with sintered magnet 12, and may replace
Existing sintered magnet must be by being manually attached at magnetic conduction casing process.
In short, sintered magnet 12 can directly be set（Do not paste additionally）In the inner side of magnetic conduction casing 14（Inner surface）Afterwards,
Sintered magnet 12 and magnetic conduction casing 14 are set by fixed relative position by fixture 16 again.
In accordance with the above, the fixed form of the present embodiment compare existing stickup fixed form it is more firm, can also keep away
Gluing is not full when exempting from existing gluing, glue examines difficult doubt, therefore the service life of magnet module 1 can also increase.
Supplementary notes, the sintered magnet 12 of the present embodiment is permanent magnet, and at least part is by iron oxide
（Ferrite）Formed.In addition, the number of the sintered magnet 12 of the present embodiment can also be multiple（By multiple sintered magnet structures
Into）, and multiple sintered magnets annularly arrange.
Then, please also refer to the second embodiment schematic diagram that Fig. 3 and Fig. 4, Fig. 3 are magnet module of the present invention.Fig. 4 is
Fig. 3 exploded perspective view.
The present invention is a kind of magnet module 1a, including sintered magnet 12a, magnetic conduction casing 14a and fixture.
It is with previous embodiment deviation, the fixture of the present embodiment is made up of multiple assemblies.Specifically,
Fixture includes the first assembly 16a and the second assembly 16b.And first assembly 16a include multiple first buckle units
162a, the second assembly 16b include multiple second buckle unit 162b, and multiple first buckle unit 162a and the multiple second cards
Detain unit 162b and define an accommodation space.Magnetic conduction casing 14a and sintered magnet 12a is fixed in accommodation space.
Similarly, the fixture of the present embodiment also may be such that magnetic conduction casing 14a and sintered magnet 12a is fixed on relative position
Put, and may replace the process that existing sintered magnet must be by being manually attached at magnetic conduction casing.And compare previous embodiment, this implementation
Fixture is divided into two sections of making by example, may be such that die cost is relatively low, processing procedure is relatively easy to.
Relation between magnet module 1a remaining component and each component is similar to previous embodiment, therefore will not be described in great detail.
Then, arranged in pairs or groups please also refer to the magnet module 1a that Fig. 5 and Fig. 6, Fig. 5 are Fig. 3 the schematic diagram of a rotor structure 2.
Fig. 6 is diagrammatic cross-sections of the Fig. 5 along A-A secants.
The magnet module 1a of the present invention applies also for a fan, and magnet module 1a can be with rotor structure after being completed
2 combinations, its combination can be to coat magnet module 1a by projecting（insert molding）, bonding, chimeric mode with
Rotor structure 2 connects.
In addition, when magnet module 1a and rotor structure 2 assemble, the manpower on production line can return previous magnet mould
Block 1a assembling operation, so kind way can replace the process of the existing manual assemble rotor structure of palpus and magnet module.Thus, this
Embodiment is actual in production, by the use cost for the artificial and board that can be reduced in process flow.
And the mode combined after being completed magnet module 1a herein with rotor structure 2, go back Strengthenable magnet mould
The fixation of sintered magnet 12a and magnetic conduction casing 14a in block 1a, positioning states.
Supplementary notes, if the present embodiment uses the magnet module 1 of first embodiment, the only palpiform of fixture 16 is into card
Catching groove body or buckle space, after sintered magnet 12 and magnetic conduction casing 14 are positioned, by projecting cladding, bonding, chimeric side
Formula closes previous mentioned snap cell body or buckle space with rotor structure 2, so that sintered magnet 12 is fixed with magnetic conduction casing 14, positioned.
The advantages of taking such a mode is, can reduce the component of fixture 16（And then reduce the overall weight of fixture 16）, also may be used
More elastic, fixture 16 the structure of design of fixture 16 can more be simplified, and then causes the cost of manufacture drop of fixture 16
It is low, it is easier to adjust and safeguards.
Magnet module application that Fig. 7 and Fig. 8, Fig. 7 are the present invention be please then refer in the schematic diagram of a fan.Fig. 8 is
Diagrammatic cross-sections of the Fig. 7 along B-B secants.
In accordance with the above, magnet module provided by the present invention applies also for fan 3（Accompanying drawing using second embodiment as
Illustrate）, and fan 3 includes housing 31, stator structure（It is not shown）, rotor structure 2 and magnet module.Rotor structure 2 can
It is connected with housing 31, rotor structure 2 may include rotating shaft 21.
And the housing 31 of fan 3 herein is formed with rotor structure 2 with that can project cladding by same process（Housing 31
Solid memder can be integrated into rotor structure 2）, the positioning and assembling of rotor structure 2 and fan 3 can be saved by such a method
Process, thus reduce cost.
Relation between remaining component and each component of magnet module is similar to previous embodiment, therefore will not be described in great detail.
In summary, the present invention by by the sintered magnet of magnet module and magnetic conduction casing with the side of fixture pre-assembly
Formula substitution is existing must be by sintered magnet and the bonding mode of magnetic conduction casing, to be glued when improving gluing caused by gluing operation
It is incomplete, glue and examine the problem of difficult.
Illustrative is the foregoing is only, rather than is restricted.Any design without departing from the present invention, and it is carried out etc.
Effect modification or change, are intended to be limited solely by appended claims scope.
