Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
Embodiment one: a kind of motor-drive circuit, for drive motors running, realizes neutral gear and two grades of rotating speed functions of motor.This motor-drive circuit comprises master control circuit plate as shown in Figure 1, and this master control circuit plate is provided with the slide switch of adjustment motor gear.And slide switch comprises the switching circuit board that the slide key for carrying out slide and the gear that matched with slide key are changed, as shown in Figure 2.Concrete, slide key has the first contact sets that four contacts connect and compose, switching circuit board then comprises second contact sets that can contact with the first contact sets, when slide key slides into diverse location, it corresponds to different gears, and contacts from the different contacts in the second contact sets.
As shown in Figure 3, the second contact sets comprises No. 0 contact and some to fixed contact.No. 0 contact is strip, and its length direction is arranged along the glide direction of slide key, and it is for increasing live width, and when slide key slides, its first contact sets all the time on slide key contacts.Some the length direction of fixed contact along No. 0 contact to be arranged, in often pair of fixed contact, comprise two contact chips, and these two contact chips are distributed in the both sides in No. 0 contact length direction.
Some two groups are divided into fixed contact, in one group of fixed contact, along No. 0 contact length direction by comprise successively after forward direction corresponding to neutral gear the first neutral gear contact to, corresponding to the power contact pair of several gears, in another group fixed contact, along the length direction of No. 0 contact by the second neutral gear contact comprised successively after forward direction corresponding to neutral gear to the operating contact pair of, several gears corresponding.First neutral gear contact to the second neutral gear contact to all corresponding to neutral gear, namely under neutral state, the first contact sets on slide key and the first neutral gear contact to the second contact neutral gear to contacting.First neutral gear contact is to No. 10 contact chips and No. 3 contact chip compositions, and the second neutral gear contact forms by No. 7 contact chips and No. 6 contact chips.During neutral gear.No. 10 contact chips and No. 3 contact chips are same electrical node, and No. 7 contact chips and No. 6 contact chips are same electrical node, and these four contact chips connect altogether.
In two groups of fixed contacts, close on a pair right power contact of the first neutral gear contact to a pair operating contact right with closing on the second neutral gear contact to corresponding to a gear, when this gear, motor low-speed running.When slide key slides, the first contact sets on it by the first neutral gear contact to the second neutral gear contact to slide into close on this to power contact to the position right to operating contact with this, thus, the power contact pair corresponding to low gear should be equal to the distance in the glide direction of slide key with the second neutral gear contact with the operating contact pair corresponding to low gear to the distance in the glide direction of slide key with the first neutral gear contact.When slide key slides into low gear, power supply connects the corresponding connection of low gear with operating contact to upper circuit, thus motor tick-over.In low gear, a pair power contact is to comprising point No. 11 contact chips being positioned at both sides, No. 0 contact length direction and No. 2 contact chips; A pair operating contact centering, comprise point vacant contact chip being positioned at both sides, No. 0 contact length direction (No. 8 contact chips) and control contact chip (No. 5 contact chips), corresponding circuit is connected with control contact chip (No. 5 contact chips).During low gear, No. 8 contact chips and No. 5 contact chips are same electrical node, and No. 11 contact chips and No. 2 contact chips are same electrical node.
In two groups of fixed contacts, be positioned at aforesaid a pair power contact to opposite side another to power contact to be positioned at aforesaid a pair operating contact to another of opposite side to operating contact to corresponding to another gear of motor, i.e. high gear, now, motor runs up.Wherein, a pair power contact is to comprising point No. 12 contact chips being positioned at both sides, No. 0 contact length direction and No. 1 contact chip; A pair operating contact centering, comprise point vacant contact chip being positioned at both sides, No. 0 contact length direction (No. 9 contact chips) and control contact chip (No. 4 contact chips), similar, the distance between this pair power contact group and the power contact group in its front should be equal with the distance between this operating contact group and the operating contact group in its front.No. 12 contact chips and No. 1 contact chip are same electrical node, and No. 9 contact chips and No. 4 contact chips are same electrical node.The contact chip (No. 11 contact chips and No. 12 contact chips, No. 1 contact chip and No. 2 contact chips) being arranged in the different electrical power contact sets of No. 0 contact homonymy during gear connects as one in the glide direction of slide key, when slide key is slided, power contact can contact with the first contact sets on slide key all the time.And in the side of No. 0 contact, the vacant contact chip (No. 4 contact chips) of an operating contact centering is adjacent with the control contact chip (No. 5 contact chips) of another operating contact centering be adjacent, and forms space therebetween in the glide direction of slide key.This adjacent vacant contact chip is connected by exposed connecting line in the glide direction of slide key with control contact chip, when slide key slides, the first contact sets on slide key can contact with exposed connecting line all the time, and the conversion of the rotating speed of motor can uninterruptedly be switched.Optimum scheme is, as shown in Figure 3, the space that exposed connecting line is covered with adjacent vacant contact chip completely and controls between contact chip, realize motor by low gear to the uninterrupted switching of high gear by the wiring of such gapless, and the design of low gear can increase buck diode to realize between power supply and motor.
Above-mentioned No. 0-12 amounts to 13 contacts or contact chip and is printing and is formed on switching circuit board.By the slip of slide key, fast, the slow two grades of controlling functions to motor can be realized.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
