Referring to shown in Figure 4; N contact-type contact 31 of peripheral disposition adopted in the fan power supply, and contact-type contact 31 comprises contact reed 31B and contact flat spring 31A, and contact flat spring 31A is arranged on fan drum sidewall 11; Contact reed 31B is arranged on fan drum end face edge 12; Contact-type contact 31 is connected with fan interior section circuit, and through connecting touch contact 31 power supply of control fan and signals, contact flat spring 31A and contact reed 31B adopt the symmetric configuration setting respectively.
Certainly, it will be understood by those skilled in the art that and to adopt multi-point touch to arrange many cover shell fragment backup power supplies and control that this structural type makes fan more safe and reliable.
Certainly; It will be understood by those skilled in the art that N contact-type contact 31 can also with the docking of the outer power pack of equipment, can be when the fan rotation be installed automatic butt; Certainly; Can also on peripheral unit, adopt auxiliary clip, the face contact mode of similar wheel brake sheet realizes fan power supply, signal input output and control fan.
When a plurality of fans need be supplied power, for example system voltage was 48V and fan when being 12V, can adopt the fan in the embodiment of the invention, and four fans through being connected in series between their the contact-type contact 31, are solved the unmatched problem of power supply voltage.
In realizing process of the present invention; The inventor finds with the fan under a fans shape wheel hub many moneys are arranged in the existing technology; Except that there is the problem of internal circuit board parts selection in some high performance fans; Cause the main cause of above-mentioned many moneys fan existence to be that the inner winding length of fan is different, though use the fan of maximum (top) speed can realize the performance of slow-speed of revolution fan through the mode of regulating rotation speed of the fan, longer relatively because of the fan winding length that rotation speed of the fan is big; When using the slow-speed of revolution, there is bigger line loss, causes bigger energy consumption waste.
In order to address the above problem, present embodiment is on the basis of the foregoing description, extends the effect of contact-type contact 31.Because general line footpath is directly proportional with rotation speed of the fan, and the number of turn and rotating speed are inversely proportional to.So; Mode equivalence through changing inner coiling serial or parallel connection changes the fan inner wire footpath and the number of turn, wherein, increases the number of turn through series connection; Increase the line footpath through the parallel connection equivalence, can realize only providing a fan to select to obtain various speed demand through different overlap joints.
Particularly, as shown in Figure 5, present embodiment; Contact-type contact 31 is a plurality of; Fan comprises terminal 40, and the winding around (not shown) in the terminal 40 comprises many, and many winding around (not shown)s comprise a plurality of terminations (not shown); Different contact-type contacts 31 is connected in series or is connected in parallel in a plurality of terminations and a plurality of contact-types contact 31; The selection of the serial or parallel connection through contact-type contact 31 in order to change winding length in the said fan, realizes selecting for use of different power consumption performance fan.
Referring to shown in Figure 5, present embodiment is through being provided with the power supply mode of contact-type contact 31 on fan drum 10, and being connected on the contact-type contact 31 segmentation of fan Inside coil; Winding arounds in the fan terminal 40 are divided into a plurality of terminations of many by two terminations of one, specifically can select the canoe of former single line to become the mode of many lines, embodiment as shown in Figure 6; Coiling in the fan can become two by one, breaks off 3. locating, wherein; 1., 2. be exactly two terminations of one, 3. punishing into two sections four terminations, embodiment as shown in Figure 7 also can select a fan winding terminal to go out modes such as pair of joint; Wherein 1., 2. expression is two coilings, the different contact-types of fan outer surface contact 31 is inserted through the fan hub support in each termination, selects through the serial or parallel connection of 31 of different contact-types contacts; Realize changing the purpose of winding length in the fan; Change fan running situation adjusting function, change inner line length and realize different maximum (top) speed fan demands, even will be that a few is a kind of with the fan normalizing under a series of; Thereby realize that a fan satisfies the adjusting of different maximum speed demands; Take into account the fan of different power consumption performance and select for use, realize compatible design, solved in the existing technology and produced a plurality of model designs with the inner winding length difference of a series of fans because of the different rotating speeds demand; Cause many moneys fan design problem with a series of different rotating speeds demands down, and satisfy the big problem of line loss, power consumption that slow-speed of revolution demand exists with a high rotating speed fan.
In addition, the embodiment of the invention also can realize the direct use of fan low voltage environment (like 12V) to high voltage environment (like 48V) through string between different fan external contact or parallel connection.
Further; Referring to shown in Figure 8; Fan comprises sliding device 51, and contact-type contact 31 is a plurality of, and a plurality of contact-types contact 31 is divided into two zones; The interconnected form of regulating 31 of the contact-type contacts in two zones through sliding device 51 is in order to realize the fan type selecting of the different maximum (top) speed different power consumption of similar fan.
Further; Referring to shown in Figure 8, fan comprises sliding device 51, and contact-type contact 31 is a plurality of and flocks together; The interconnected form of regulating 31 of the contact-type contacts that flock together through sliding device 51 is in order to realize the fan type selecting of the different maximum (top) speed different power consumption of similar fan.
More specifically; In the present embodiment; Serial or parallel connection for 31 of a plurality of contact-types contacts on the fan drum 10; Can be like 31 zones, Fig. 5 separated into two parts contact-type contact; Realization overlap joint serial or parallel connection perhaps can gather Yu Yichu with a plurality of contact-types contact 31 in the periphery, makes a slide rheostat formula sliding device 51 (ginseng Fig. 8) or make a compass formula sliding device 52 (referring to Fig. 9) to be connected with contact-type contact 31; Through when using fan, regulating the scribing 51A (referring to Fig. 8) of slide rheostat or realize the interconnected form of 31 of contact-type contacts through slide bar 51B in advance, realize the purpose of the fan type selecting of the different maximum (top) speed different power consumption of similar fan through the adjusting compass 52A (referring to Fig. 9) of compass needle 52B.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
