Embodiment
Figure 1A illustrates the decomposing schematic representation of the blower module of one embodiment of the invention.Figure 1B illustrates the assembling schematic representation of the blower module of one embodiment of the invention, and Fig. 1 C illustrates the regional A of circuit board of Figure 1B and the enlarged diagram that electric connection part electrically connects.Please refer to Fig. 1 C, blower module 100 need not use insulated conductor, but utilizes the electric connection part E on one group of electric terminal S and the support plate 200 (for example host board of computer) to electrically connect.Electric terminal S for example is plane terminal (being commonly called as golden finger), in order to receive power supply and pilot signal, and electric connection part E for example is an electroconductive elastic sheet, the curved part of electroconductive elastic sheet directly contacts with the surface of electric terminal S and forms a connecting structure for electrical equipment, so need not use insulated conductor to transmit or receive signal.Below describe in detail at the structure of blower module 100.
Please refer to Figure 1A and Figure 1B, blower module 100 comprises a housing 110, a circuit board 110a, a motor (not illustrating) and a flabellum 120.Flabellum 120 and groups of motors are located at a containing space of housing 110.Circuit board 110a connects motor controlling the running of this motor, and then drives flabellum 120 rotations.For instance, flabellum 120 is fixed in the periphery of a wheel hub 130, and can produce an air-flow along the rotation of the axle center of wheel hub 130.Motor drives flabellum 120 with predetermined rotating speed rotation, and the air-flow that flabellum 120 is produced can flow towards an exhaust outlet 102, and the torrid zone that thermal source produced is walked, to reduce the temperature of system.
Though present embodiment does not illustrate a controller or a processor, well imagine that controller electrically connects circuit board 110a or support plate 200, and can control the signal between circuit board 110a and the support plate 200.For example, in case when the temperature of system was lower than default temperature, controller can cut off the power supply that is supplied to blower module 100, and the electric terminal S of circuit board 110a no longer receives power supply, so that flabellum 120 stops the rotation.In case when the temperature of system was higher than default temperature, controller was opened the power supply that is supplied to blower module 100 again, and the electric terminal S of circuit board 110a receives power supply, so that flabellum 120 rotations.
It should be noted that, for electric terminal S is revealed on the surface (for example the bottom surface 112) of circuit board 110a, circuit board 110a among the present invention is as a cover plate of housing 110, finish electric connection to make things convenient for electric terminal S directly to contact conducting with the electric connection part E of support plate 200, so do not need earlier an end of insulated conductor is welded on the electric terminal, the joint by the other end of insulated conductor is inserted on the slot of support plate again.In Fig. 1, housing comprises a fan frame 110b, and the periphery of circuit board 110a combines with the periphery of fan frame 110b, to constitute a complete housing 110.Therefore, circuit board 110a can be as the cover plate of housing 110.
In addition, in the present embodiment, the central authorities of circuit board 110a for example have a vacancy section H, but do not limit.Vacancy section H can allow air outside enter in housing 110, and produces an air-flow via the rotation of flabellum 120.The inside of vacancy section H for example has a plate body 114 and a plurality of adjutage 116, and plate body 114 is supported and forms a supporting portion in a plurality of adjutages 116 of vacancy section H by cross-over connection.The supporting portion can be in order to assemblies such as configuration wheel hub 130 and electric motors, and its configuration mode is not described in detail in this.In present embodiment, electric terminal S is positioned at bottom surface 112 near circuit board 110a peripheral region, but is not limited thereto.
Then, please refer to the exploded view and the ssembly drawing of the blower module of Fig. 2 A and Fig. 2 B, and Fig. 2 C illustrates the area B of circuit board of Fig. 2 B and the partial schematic diagram that electric connection part electrically connects.In another embodiment, the configuration mode of circuit board 110a and fan frame 110b is same as the previously described embodiments haply, and difference only is that circuit board 110a also has a protuberance P, extend the periphery of fan frame 110b, and electric terminal S is positioned at protuberance P.The shape of protuberance P is as the shape of plug, thus present embodiment can be inserted in the slot 202 by the protuberance P of side direction configuration so that electroconductive elastic sheet 204 electric connections in electric terminal S and the slot 202.Hence one can see that, and the electric connection part E of support plate 200 is made of slot 202 and a plurality of electroconductive elastic sheets 204 of being positioned at slot 202, equally need electrically connect by insulated conductor and electric terminal.
Then, please refer to the exploded view and the ssembly drawing of the blower module of Fig. 3 A and Fig. 3 B.In another embodiment, housing 110 comprises a fan frame 110b and a cover plate 110c.Cover plate 110c for example is the plastic material of insulation, and the periphery of cover plate 110c combines with the periphery of fan frame 110b.But cover plate 110c protective circuit plate 110a or the whole structural strength of increase.In addition, the shape of cover plate 110c is as the shape of the circuit board of the foregoing description, at this moment, and the dashed region shown in the shape of circuit board 110a can be reduced into, but the present invention is not limited for the combination of cover plate 110c and circuit board 110a, can be designed to different shapes yet.The central authorities of cover plate 110c for example have a vacancy section H1, can allow air outside enter in housing 110.The inside of vacancy section H1 for example has a plate body 114a and a plurality of adjutage 116a, and plate body 114a is supported by the adjutage 116a of cross-over connection in vacancy section H1 and form a supporting portion.
In order to make the circuit board 110a can be as the part of cover plate 110c, that is circuit board 110a and cover plate 110c integrate, circuit board 110a can be combined with the plate body 114a of cover plate 110c, but for example plate body 114a is hollowed out and form the fluting (not illustrating) of a containment circuit board 110a, so circuit board 110a can be revealed in the fluting, and manifests the electric terminal S of circuit board 110a.In addition, in Fig. 3 A, if circuit board 110a is not as the part of cover plate 110c, but as known fan circuit plate when being disposed on fan and the motor, circuit board 110a is folded mutually with the plate body 114a of cover plate 110a, but plate body 114a has an open C, can manifest electric terminal S.Therefore,, but, all can utilize the electric connection part E on electric terminal S and the support plate 200 to electrically connect, need not use known insulated conductor as long as the electric terminal S of circuit board 110a can reveal even housing 110 has increased cover plate 110c.
In sum, blower module of the present invention need not use insulated conductor, can avoid insulated conductor to be pullled and joint is come off, and avoid insulated conductor and flabellum in the rotation to interfere and impaired.The present invention utilizes the electric terminal of electroconductive elastic sheet and circuit board to electrically connect, that is finishes electric connection in the mode of no lead, can improve above-mentioned shortcoming, and make things convenient for blower module to be assembled on the support plate.In addition, utilize circuit board as a cover plate of housing or as the part of cover plate, escapable cost not only more can reduce the height of blower module, and the inside of reducing mobile computer takes up room, to reach the requirement of thin typeization.
Though the present invention discloses as above with embodiment; right its is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; without departing from the spirit and scope of the present invention; when doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the claim person of defining.
